<power supply unit>

Figure 3 is a cross-sectional view taken along line III-III of Figure 1.

As shown in FIG. 3, the power supply unit 21 includes a housing 31 and a bracket assembly 32 housed in the housing 31.

(Bracket assembly)

FIG. 4 is an exploded perspective view of the power supply unit 21.

As shown in FIGS. 3 and 4, the holder assembly 32 is configured by mounting the battery 33, the substrate module (the first substrate module 34 and the second substrate module 35) on the battery holder 36.

The battery holder 36 is formed integrally by, for example, a resin material. The battery holder 36 includes a base 40. The base 40 is formed in a semi-cylindrical shape with the axis O as the central axis. If the base portion 40 is opened outward in the radial direction to form an attachment opening 40a (see FIG. 4) into which the battery 33 or the like is installed, it may be a shape other than a semi-cylindrical shape.

An end portion of the base portion 40 on the opposite side of the holding unit 22 in the axial direction is connected to the press-fit tube portion 41. The press-fit cylinder 41 is formed in a cylindrical shape with the axis O as the central axis. A part of the circumferential direction of the press-fitting cylinder 41 is formed with a connector passage hole 42 penetrating the press-fitting cylinder 41 in the radial direction. The opening portion which is pressed into the cylindrical portion 41 and is located on the opposite side to the holding unit 22 in the axial direction is blocked by the blocking portion 43. The blocking portion 43 is formed in a circular shape having a diameter larger than that of the press-fit tube portion 41.

In the base portion 40, a button opening 44 (see FIG. 3) is formed in a portion located on the holding unit 22 side in the axial direction. The button opening 44 penetrates a part of the circumferential direction of the base 40 in the radial direction. The connector passing hole 42 and the button opening 44 are arranged at positions different from each other by 180° in the circumferential direction, for example. In this embodiment, the radial direction passing through the center of the connector passage hole 42 and the center of the button opening 44 in the circumferential direction is defined as the front and back directions. In this case, the connector passage hole 42 side is defined as the back side with respect to the axis O, and the button opening 44 side is defined as the front side with respect to the axis O. In addition, the positions of the connector passage hole 42 and the button opening 44 can be appropriately changed.

In the base 40, a button guide tube 45 extending toward the back side is formed at the opening edge of the button opening 44. The button guide cylinder 45 surrounds the button opening 44.

In the base portion 40, a partition wall 46 that axially separates the base portion 40 is formed in a portion of the button opening 44 that is closer to the opposite side of the holding unit 22 in the axial direction.

Figure 5 is a cross-sectional view taken along line V-V of Figure 1.

As shown in FIGS. 3 to 5, in the base portion 40, a step portion 47 is connected to the end portion on the holding unit 22 side in the axial direction. The step portion 47 is formed in a semi-cylindrical shape coaxially arranged with the base portion 40, and the radial distance from the axis O gradually decreases as the axial direction approaches the holding unit 22. An end edge of the stepped portion 47 located on the side of the holding unit 22 in the axial direction is connected with a connecting base 48. The connection base 48 is formed in a circular shape with the axis O as the central axis. The connection pedestal 48 is formed with a pair of electrode holding portions 50 and a communication port 51.

As shown in FIGS. 4 and 5, the pair of electrode holding portions 50 is formed in a cylindrical shape protruding toward the holding unit 22 side in the axial direction. Each electrode holding portion 50 is located on both sides in the radial direction with respect to the axis O. In this embodiment, each electrode holding portion 50 is arranged side by side in the radial direction and above The direction orthogonal to the back direction (hereinafter sometimes referred to as the left-right direction) will be described. Furthermore, each electrode holding portion 50 extends in the axial direction and is connected in the radial direction.

As shown in FIGS. 3 and 4, the communication port 51 is connected to the connection base 48 and protrudes from the portion on the radial back side with respect to the axis O toward the holding unit 22 side in the axial direction.

As shown in FIG. 5, each electrode holding portion 50 holds a thimble electrode 49. The thimble electrode 49 is a structure in which a needle-shaped electrode body is elastically supported in a cylindrical case. The thimble electrode 49 is configured such that the electrode body penetrates the electrode holding portion 50 in the axial direction when the cylindrical case is embedded in the electrode holding portion 50. Of the two axial end portions of the thimble electrode 49 (electrode body), the end portion on the opposite side to the holding unit 22 in the axial direction is connected to the first substrate (substrate) described later through electrode wiring in the battery holder 36 60 connections.

The battery 33 is formed in a cylindrical shape with the axis O as the axial direction. The battery 33 is housed in the base portion 40 on the side opposite to the holding unit 22 with respect to the partition wall 46 in the axial direction. The power supply unit mounted on the taste absorber 1 is not limited to the secondary battery such as the storage battery 33, and a super capacitor or the like can also be used as a power source that can be charged and discharged. In addition, the power supply unit may also use a primary battery.

As shown in FIGS. 3 and 4, the first substrate module 34 is disposed in the portion of the base 40 that is located on the side of the holding unit 22 in the axial direction with respect to the partition wall 46. Specifically, the first substrate module 34 includes the first substrate 60, the switching element 52 (see FIG. 3 ), and the pressure sensor 53.

The first substrate 60 is arranged so that its thickness direction becomes the front-back direction. Specifically, the first substrate 60 is fixed to the base 40 with screws or the like in a state where it is placed on the opening end surface of the mounting opening 40a. The first substrate 60 is connected to the battery 33 through the first connection wiring (not shown). In addition, in the example shown in FIG. 3, the first substrate 60 is located on the axis O.

The switching element 52 is arranged on the front surface (first main surface) of the first substrate 60 and is arranged at a position overlapping the button opening 44 when viewed from the front and back directions. In this embodiment, the switching element 52 is mounted on the first substrate 60 by surface mounting. However, the switching element 52 can also be mounted on the first substrate 60 with the connection terminal extending from the switching element 52 inserted into the through hole of the first substrate 60.

The pressure sensor 53 is arranged on the back surface (second main surface) of the first substrate 60 with respect to the switching element 52 on the holding unit 22 side in the axial direction. That is, the pressure sensor 53 is arranged at a position where it does not overlap with the switching element 52 when viewed in the plane seen from the front and back direction. In the present embodiment, the pressure sensor 53 is arranged at a position shifted toward the holding unit 22 in the axial direction with respect to the switching element 52, but it is not limited to this configuration. In other words, if the switching element 52 and the pressure sensor 53 are arranged at positions offset in the in-plane direction of the first substrate 60, they may also be arranged at positions offset in the axial direction toward the opposite side of the holding unit 22, Or, they are arranged offset in the left-right direction in the radial direction.

The pressure sensor 53 may be, for example, an electrostatic capacitance type pressure sensor. That is, the pressure sensor 53 detects the change in the diaphragm deformed as the pressure changes as a change in electrostatic capacity. The pressure sensor 53 of the present embodiment is mounted on the first substrate 60 in a state where the connection terminal pulled out from the pressure sensor 53 is inserted into the through hole of the first substrate 60. However, the pressure sensor 53 can also be mounted on the first substrate 60 by surface mounting.

The pressure sensor 53 is provided with a sensor holder (partition member) 54. The sensor holder 54 is formed of a resin material such as polysiloxane resin that is softer and more elastic than the battery holder 36. The sensor holder 54 includes an attachment portion 55 attached to the battery holder 36 and a covering portion 56 covering the pressure sensor 53.

The attachment portion 55 is formed in a semicircular shape. The attachment portion 55 is attached to the battery holder 36 in a state of being in contact with the connection base 48 from the side opposite to the holding unit 22 in the axial direction. In addition, the stepped portion 47 is formed with a clamping piece 57 (see FIG. 4 ), and the mounting portion 55 is clamped between the clamping piece 57 and the connection base 48 in the axial direction. The clamping piece 57 protrudes from the both ends of the arc of the stepped portion 47 located on the outer side in the radial direction (left-right direction) in the circumferential direction.

The covering portion 56 is formed continuously from the mounting portion 55 toward the side opposite to the holding unit 22 in the axial direction. The covering portion 56 is formed in a lid shape that is opened on the front side. The bottom wall portion 56a of the covering portion 56 is formed with a partition portion 56b that swells toward the surface side. The pressure sensor 53 is fitted into the covering portion 56 in a state of being in contact with the partition portion 56b. Therefore, a radial gap is provided between the inner surface of the bottom wall portion 56a and the pressure sensor 53. In addition, the bottom wall portion 56a is formed with an air replacement hole 58 penetrating the bottom wall portion 56a in the radial direction.

The mounting portion 55 is formed with a communication path 59 that communicates the inside of the communication port 51 and the covering portion 56. The communication path 59 extends in the axial direction in the mounting portion 55. The end of the communication path 59 on the side opposite to the holding unit 22 in the axial direction is opened on the inner peripheral surface of the covering portion 56. On the other hand, the end of the communication path 59 in the axial direction on the side of the holding unit 22 is opened on the surface of the mounting portion 55 facing the side of the holding unit 22 in the axial direction. In this embodiment, the minimum inner diameter of the communication path 59 is larger than the maximum inner diameter of the air replacement hole 58. In addition, in the communication path 59, the inner diameter of at least the end of the holding unit 22 side in the axial direction is larger than the inner diameter of the communication port 51.

In the present embodiment, the communication port 51 and the communication path 59 are arranged at positions where at least a part overlaps the pressure sensor 53 when viewed from the axial direction. However, the communication port 51 and the communication path 59 may also be arranged at positions offset from the pressure sensor 53 when viewed from the axial direction.

As shown in FIGS. 3 to 5, the second substrate module 35 is arranged on the side opposite to the first substrate module 34 in the axial direction via the battery 33. That is, the substrate modules 34 and 35 of this embodiment are arranged on both sides in the axial direction with the battery 33 interposed therebetween. The second substrate module 35 includes a second substrate 61 and a female connector 62.

The second substrate 61 is housed in the press-fit cylinder 41 with its thickness direction in the radial direction (front-back direction). As shown in FIG. 5, the second substrate 61 is placed on the convex column portion 41 a protruding radially inward from the press-fit tube portion 41, and is fixed to the convex column portion 41 a with screws or the like. The second substrate 61 is connected to the first substrate 60 through the second connection wiring 61a. That is, the second connection wiring 61a is attached to the outside of the battery holder 36, and is drawn along the axial direction around the battery 33.

As shown in FIG. 3 and FIG. 4, the female connector 62 is used to insert a male connector (not shown) drawn from an external power source when charging the battery 33. In this embodiment, the female connector 62 is, for example, a USB connector (Universal Serial Bus). However, the female connector 62 is not limited to the USB connector. In addition, the female connector 62 is not necessarily used for charging, and may also be used for communication purposes, for example.

The female connector 62 is mounted on the second substrate 61 with the opening toward the back side. The front end portion (the end portion near the opening) of the female connector 62 is inserted into the connector passing hole 42. However, the female connector 62 may also be set to retract radially inward from the connector through hole 42.

As shown in FIG. 3 and FIG. 4, the housing 31 includes an exterior cylinder 71, an intermediary member 72, and a connection mechanism 73.

The exterior cylindrical portion 71 is formed in a cylindrical shape with the axis O as the central axis. The holder assembly 32 is inserted into the exterior cylindrical portion 71 through an opening on the side opposite to the holding unit 22 in the axial direction. Specifically, the holder assembly 32 is assembled into the exterior cylindrical portion 71 in a state where the press-fitting cylindrical portion 41 of the battery holder 36 is pressed into the end portion of the exterior cylindrical portion 71 on the side opposite to the holding unit 22. Therefore, the bracket assembly 32 is housed in the exterior cylindrical portion 71 in a state where the end portion on the holding unit 22 side in the axial direction protrudes from the exterior cylindrical portion 71. In addition, the opening of the exterior cylindrical portion 71 on the side opposite to the holding unit 22 in the axial direction is blocked by the blocking portion 43 of the battery holder 36.

The outer cylindrical portion 71 has an end portion on the opposite side to the holding unit 22 in the axial direction, and a connector exposure hole 75 is formed in a portion overlapping the connector passing hole 42 and the female connector 62 when viewed from the radial direction . The connector exposure hole 75 penetrates the exterior cylindrical portion 71 in the radial direction. In this embodiment, the configuration in which the female connector 62 opens in the radial direction is described, but the configuration in which the female connector 62 opens in the axial direction may also be used.

The end portion of the exterior cylindrical portion 71 in the axial direction on the side of the holding unit 22 has a button exposure hole 76 formed at a portion overlapping the button opening 44 when viewed from the radial direction. The button exposure hole 76 penetrates the exterior cylindrical portion 71 in the radial direction.

Button 78 is accommodated in button exposure hole 76 and button opening 44. The button 78 is configured to be movable in the radial direction while being supported by the button guide cylinder 45. The button 78 presses the operation switch element 52 as it moves radially inward. The surface of the button 78 is exposed through the button exposure hole 76 to expose the outer peripheral surface of the exterior cylinder 71. The button 78 is not limited to moving in the radial direction, and may also slide in the axial direction, for example. In addition, it is also possible to use a touch sensor or the like instead of the button 78 to operate the taste absorber 1.

The interposing member 72 is formed in a cylindrical shape with the axis O as the central axis. The interposition member 72 is fitted between the holder assembly 32 and the exterior cylinder 71 from the axial holding unit 22 side. borrow Thus, the gap between the bracket assembly 32 and the exterior cylindrical portion 71 is sealed at the opening of the exterior cylindrical portion 71 on the holding unit 22 side in the axial direction.

As shown in FIG. 3, in the housing 31, the space surrounded by the sensor holder 54 is configured to change in pressure through the communication port 51 as the taster 1 is used (suction). Room S1. On the other hand, in the housing 31, the space other than the pressure fluctuation chamber S1 is configured as a normal pressure chamber S2 communicating with the atmospheric pressure. In this embodiment, of the battery 33 and the substrate modules 34 and 35, components other than the pressure sensor 53 are housed in the normal pressure chamber S2. However, if at least the pressure sensor 53 is accommodated in the pressure fluctuation chamber S1, parts other than the pressure sensor 53 may also be accommodated in the pressure fluctuation chamber S1. In addition, in the case 31, in order to confirm whether liquid enters the case 31, a liquid detection seal or the like may be provided.

<connecting mechanism>

As shown in FIGS. 4 and 5, the connection mechanism 73 includes a connection cover 80, a first connection member 81, and an annular piece 82.

The connection cover 80 is formed of a resin material such as polysiloxane resin that is softer and more elastic than the battery holder 36. The connection cover 80 is attached to the connection base 48 from the axial holding unit 22 side. The connection cover 80 has a base portion 91, a flange portion 92, and a surrounding convex portion 93.

As shown in FIG. 5, the base 91 is formed in a cylindrical shape with the axis O as the central axis. In the base portion 91, at positions overlapping with the electrode holding portions 50 when viewed in plan, storage recesses 95 that are recessed toward the holding unit 22 side in the axial direction are respectively formed. Each receiving recess 95 extends in the axial direction and is connected in the radial direction. In the base portion 91, an electrode insertion hole 97 is formed at a position overlapping with each storage recess 95 when viewed in plan. The electrode insertion hole 97 penetrates the base portion 91 in the axial direction and communicates with the inside of the housing recess 95.

As shown in FIG. 3, in the base 91, a port insertion hole 99 is formed at a position overlapping with the communication port 51 when viewed in plan. The port insertion hole 99 penetrates the base 91 in the axial direction.

As shown in FIGS. 3 and 5, in the connection cover 80, the electrode holding portion 50 is accommodated in each accommodating recess 95, and the communication port 51 is inserted into the port insertion hole 99. Therefore, the connection cover 80 is attached to the battery holder 36 in a state of being in contact with the end surface of the connection pedestal 48 toward the holding unit 22 side in the axial direction. In this state, the thimble electrode 49 protrudes from the base 91 toward the holding unit 22 in the axial direction through the electrode insertion hole 97, and the communication port 51 is a holding unit toward the axial direction from the base 91 through the port insertion hole 99 22 side protruding. That is, in the connection cover 80 (base portion 91 ), the surface facing the holding unit 22 side is configured as a base surface 91 a that protrudes with the thimble electrode 49 and is opened by the communication port (communication port) 51.

The flange portion 92 is at the end of the base portion 91 on the side opposite to the holding unit 22 in the axial direction, and protrudes outward in the radial direction.

The surrounding convex portion 93 protrudes in the axial direction from the end surface of the base portion 91 toward the holding unit 22 side in the shaft. Specifically, the surrounding convex portion 93 is formed in a ring shape that protrudes along the outer peripheral edge of the base portion 91. That is, the surrounding convex portion 93 is positioned radially outward from the thimble electrode 49 and the communication port 51 and is generally surrounded by the thimble electrode 49 and the communication port 51. In addition, if the surrounding convex portion 93 is configured to generally surround the thimble electrode 49 and the communication port 51, it may be located radially inward with respect to the outer peripheral edge of the base portion 91. In addition, the surrounding convex portion 93 is not limited to a ring shape, and may be polygonal or the like. In the present embodiment, the so-called "surround" is not limited to continuous extension, but also includes intermittent extension. That is, the surrounding convex portion 93 in the present embodiment as a whole can be appropriately changed as long as it is configured to surround the thimble electrode 49 and the communication port 51.

The surrounding convex portion 93 is formed into a triangular shape which is tapered toward the holding unit 22 side in the axial direction when viewed in the longitudinal cross-sectional view along the axial direction. The protrusion height from the base portion 91 around the convex portion 93 is higher than the communication port 51 and lower than the thimble electrode 49. However, the protruding height around the convex portion 93 may also be higher than the thimble electrode 49. In addition, the shape when viewed around the longitudinal section of the convex portion 93 is not limited to a triangle.

The first coupling member 81 includes a base cylindrical portion 100, a vertical engaging convex portion (first vertical engaging convex portion 101a to third vertical engaging convex portion 101c), and a horizontal engaging convex portion 102.

The base cylindrical portion 100 is formed in a multi-stage cylindrical shape centered on the axis O and gradually decreasing in diameter toward the holding unit 22 side in the axial direction. The end of the base cylinder portion 100 on the opposite side to the holding unit 22 is embedded inside the interposition member 72. In this state, the end portion of the base cylinder portion 100 in the axial direction on the holding unit 22 side surrounds the connection cover 80 with the flange portion 92 sandwiched between the connection base 48 and the axial direction in the axial direction. An end portion of the base cylinder portion 100 on the axial side of the holding unit 22 side is formed with an outer flange portion 105 that protrudes outward in the radial direction.

FIG. 6 is a perspective view of the power supply unit 21.

As shown in FIGS. 5 and 6, the vertical engagement convex portions 101 a to 101 c protrude from the base cylindrical portion 100 toward the holding unit 22 side in the axial direction. Each of the vertical engagement convex portions 101a to 101c is formed at intervals in the circumferential direction. In the present embodiment, the vertical engaging convex portions 101a to 101c are arranged at equal intervals of 120° in the circumferential direction. In addition, the vertical engagement convex portions 101a to 101c may be single or plural. In addition, the pitch of the vertical engagement convex portions 101a to 101c can be appropriately changed. At this time, the plural vertical engagement convex portions 101a to 101c may be arranged unevenly.

FIG. 7 is a plan view when the power supply unit 21 is viewed from the axial holding unit 22 side.

As shown in FIG. 7, the vertical engagement convex portions 101a to 101c are arranged so that the thimble electrode 49 is not positioned on an imaginary straight line connecting the circumferential center of the vertical engagement convex portions 101a to 101c with the axis O La~Lc. Specifically, the thimble electrode 49 is arranged at a position symmetrical with respect to an imaginary straight line La connecting the first vertical engagement convex portion 101a and the axis O. That is, the virtual straight line T1 connecting the two thimble electrodes 49 and the virtual straight line La are orthogonal to each other, and the distance from the virtual straight line La to each thimble electrode 49 is equal.

As shown in FIGS. 5 and 6, the end edges of the vertical engagement convex portions 101 a to 101 c on the axial holding unit 22 side are located on the axial holding unit 22 side more than the thimble electrode 49. When viewed from the side in the radial direction, the vertical engagement convex portions 101a to 101c have a rectangular shape. In the end portions of the longitudinal engagement convex portions 101a to 101c in the axial direction on the holding unit 22 side, the surface toward the radial inner side is formed to be inclined with the radial thickness gradually decreasing toward the axial side of the holding unit 22 side surface. This inclined surface functions as a guide member for smoothly guiding the vertical engagement convex portions 101 a to 101 c to the engagement concave portion 210 described later of the cassette 11.

The lateral engagement convex portion 102 protrudes radially outward from the outer flange portion 105. When viewed in a plane, the lateral engagement convex portion 102 is formed into a rectangular shape. The plurality of lateral engagement convex portions 102 are formed at intervals in the circumferential direction. In the present embodiment, each lateral engagement convex portion 102 is evenly arranged at 90° intervals in the circumferential direction. In this embodiment, one horizontal engagement convex portion 102 is arranged at the same position as the first vertical engagement convex portion 101a in the circumferential direction. In addition, the lateral engagement convex portions 102 may be single or plural. In addition, the pitch of the lateral engagement convex portions 102 can be appropriately changed. At this time, the plurality of lateral engagement convex portions 102 may be unevenly arranged.

The ring-shaped piece 82 is formed into a thin ring shape. The ring-shaped piece 82 is inserted into the above-mentioned base cylinder portion 100 from the axial holding unit 22 side, and is sandwiched between the interposing member 72 and the outer flange portion 105. As shown in FIG. 5, in the ring-shaped piece 82, a flexure 106 is formed in a part of the circumferential direction. The flexure 106 is formed into an arch shape that bulges outward in the radial direction. The flexure 106 is configured to be elastically deformable in the radial direction. The flexure 106 is more radially inward than the radially outer end surface of the lateral engagement convex portion 102.

A plurality of the above-mentioned flexures 106 are formed at intervals in the circumferential direction. For example, the flexure 106 is disposed at the same position in the circumferential direction as the pair of lateral engagement convex portions 102 facing the radial direction (left-right direction) of each lateral engagement convex portion 102. However, the number of flexures 106 can be changed as appropriate. For example, the flexure 106 may be formed corresponding to each lateral engagement convex portion 102, or may be formed corresponding to only one lateral engagement convex portion 102.

<hold unit>

FIG. 8 is an exploded perspective view of the holding unit 22.

As shown in FIG. 8, the holding unit 22 is attached to and detachable from the body unit 10. Specifically, the holding unit 22 includes a container holding cylinder 120, a transparent cylinder 121, a second coupling member 122, and a sleeve 123.

The container holding cylinder 120 is formed in a cylindrical shape with the axis O as the central axis. An observation hole 130 is formed in the central portion of the container holding cylinder 120 in the axial direction. The observation hole 130 penetrates the container holding cylinder 120 in the radial direction. The observation hole 130 is formed in an oblong shape with the axial direction as the long side direction. The observation holes 130 are attached to the container holding cylinder 120, and form a pair in the radially opposed portions. The number, position, shape, etc. of the observation holes 130 can be changed as appropriate.

A vent 131 is formed in a portion of the container holding cylinder 120 that is closer to the power supply unit 21 side than the observation hole 130 in the axial direction. The vent 131 penetrates the container holding cylinder 120 in the radial direction. The vent 131 communicates the inside and outside of the holding unit 22. The vent 131 is held by the container In the cylinder 120, a pair is formed in a portion facing each other in the radial direction (front-back direction). The number, position, shape, etc. of the vent 131 can be changed as appropriate.

The transparent cylinder 121 is formed of a material having light transmittance. The transparent cylinder 121 is inserted into the container holding cylinder 120. Specifically, the transparent cylinder 121 is housed in the container holding cylinder 120, is closer to the suction nozzle 23 side than the vent 131 in the axial direction, and covers the observation hole 130 from the radially inner side. That is, the user can see the inside of the holding unit 22 through the observation hole 130 and the transparent tube 121. The holding unit 22 may be configured without the observation hole 130 and the transparent tube 121.

The second coupling member 122 is engaged with the first coupling member 81 when the holding unit 22 is attached to the body unit 10. Specifically, the second coupling member 122 includes a fitting tube 140, a guide tube 141, and a locking piece 142.

The fitting tube 140 is formed in a cylindrical shape with the axis O as a central axis. The fitting cylinder 140 is fitted into the container holding cylinder 120 by press-fitting or the like, and is a portion closer to the power supply unit 21 side than the transparent cylinder 121 in the axial direction.

The guide tube 141 is arranged coaxially with the fitting tube 140. The guide cylinder 141 extends from the fitting cylinder 140 toward the suction nozzle 23 side in the axial direction. The guide cylinder 141 is formed in a tapered cylindrical shape that gradually enlarges as the inner diameter of the suction nozzle 23 side in the axial direction increases. The outer diameter of the guide cylinder 141 is smaller than the outer diameter of the fitting cylinder 140. In the guide tube 141, when viewed from the side in the radial direction, a retracted portion 145 is formed at a position overlapping with the vent 131. The retracted portion 145 is formed into, for example, a U shape that opens toward the suction nozzle 23 side in the axial direction. The vent 131 is opened in the holding unit 22 through the retracted portion 145. In addition, the shape of the retracted portion 145 may be a shape that can expose at least a part of the vent 131 in the holding unit 22. In addition, when the guide cylinder 141 and the vent 131 are arranged at different positions in the axial direction, the guide cylinder 141 may not have a retracted portion 145.

FIG. 9 is a perspective view showing the connection structure of the first connection member 81 and the second connection member 122.

As shown in FIGS. 8 and 9, the locking piece 142 protrudes from the fitting tube 140 toward the power supply unit 21 side in the axial direction. When viewed from the side in the radial direction, the locking piece 142 is formed into an L-shape. Specifically, the locking piece 142 has a vertically extending portion 150 and a laterally extending portion 151.

The vertically extending portion 150 protrudes from the fitting tube 140 toward the power supply unit 21 side in the axial direction.

As shown in FIG. 9, the horizontally extending portion 151 extends from the end of the longitudinally extending portion 150 on the power supply unit 21 side in a cantilever manner in one direction in the circumferential direction.

FIG. 10 is a plan view of the holding unit 22 and the case 11 viewed from the power supply unit 21 side in the axial direction.

As shown in FIG. 9 and FIG. 10, an end portion in one direction in the circumferential direction of the laterally extending portion 151 is formed with an engagement recessed portion 155 recessed outward in the radial direction. The engaging recess 155 is formed in a semicircle toward the outside in the radial direction.

The locking pieces 142 are formed at intervals in the circumferential direction. In the present embodiment, the locking pieces 142 are arranged at equal intervals of 90° in the circumferential direction. An engaging groove 158 into which the above-mentioned horizontal engaging convex portion 102 is inserted is formed between the engaging pieces 142 adjacent in the circumferential direction. When viewed from the side, the engaging groove 158 is formed into an L shape.

As shown in FIG. 2 and FIG. 9, the power supply unit 21 and the holding unit 22 are detachable because the locking piece 142 is connected to the lateral engagement convex portion 102. That is, when connecting the power supply unit 21 and the holding unit 22, the horizontal engagement convex portion 102 is inserted into the engagement groove 158 in the axial direction, and then the power supply unit 21 and the holding unit 22 are relatively rotated about the axis O as the center. In this way, the lateral engagement convex portion 102 is axially engaged between the lateral extension portion 151 and the fitting tube 140. Moreover, in the power supply unit 21 During the relative rotation of the holding unit 22 about the axis O, the flexure 106 of the ring-shaped piece 82 is fitted into the engagement recess 155. As a result, the flexure 106 is engaged with the engagement recess 155 in the circumferential direction. As a result, the power supply unit 21 and the holding unit 22 are combined in a state where both the axial direction and the circumferential direction are positioned.

As shown in FIG. 9, in the engagement groove 158 of this embodiment, the width between the fitting cylinder 140 and the laterally extending portion 151 is formed to gradually change from one direction to another direction in the circumferential direction Narrow inclined shape. Specifically, the end surface of the suction nozzle 23 in the axial direction of the laterally extending portion 151 is formed as an inclined surface that extends toward the power supply unit 21 side in the axial direction as it goes from one direction in the other circumferential direction to one direction.

The lateral engagement convex portion 102 is formed in an inclined shape in which the width in the axial direction gradually narrows from one direction to the other in the circumferential direction. Specifically, the end surface of the lateral engagement convex portion 102 on the side opposite to the holding unit 22 in the axial direction is formed as a suction nozzle toward the axial direction from one direction in the circumferential direction to the other direction Inclined surface extending on 23 sides. Thereby, when the power supply unit 21 and the holding unit 22 are connected, interference between the laterally extending portion 151 and the laterally engaging convex portion 102 can be suppressed, and the assembly can be improved.

As shown in FIG. 8, the sleeve 123 is embedded in the container holding cylinder 120 by press-fitting or the like, and is located on the suction nozzle 23 side of the transparent cylinder 121 in the axial direction. The transparent tube 121 is axially held between the second coupling member 122 and the sleeve 123. A female screw portion 123a is formed on the inner circumferential surface of the sleeve 123.

The male screw portion 160a of the suction nozzle body 160 is detachably screwed to the female screw portion 123a of the sleeve 123. In addition, the suction nozzle body 160 may be configured to attach and detach the sleeve 123 by a method other than screwing (for example, fitting).

In the suction nozzle body 160, a contact flange 165 is formed at a portion on the opposite side of the holding unit 22 with respect to the axial direction of the male screw portion 160a. The contact flange 165 is formed in a ring shape protruding radially outward. The contact flange 165 is axially contacted with the holding unit 22 in a state where the suction nozzle 23 is attached to the holding unit 22. In addition, the outer diameter of the contact flange 165 gradually decreases as it moves away from the holding unit 22 in the axial direction.

An end portion of the suction nozzle body 160 on the axial holding unit 22 side is formed with a partition portion 167 that axially separates the space in the suction nozzle body 160. In the partition 167, a through hole 168 penetrating the partition 167 in the axial direction is formed at a position overlapping the axis O. The through hole 168 is formed in an oblong shape with one direction in the radial direction as the longitudinal direction, for example. In addition, when viewed in a plane, the shape of the through hole 168 may be a perfect circle or a polygon.

The first anti-slip member 161 is integrally formed of a resin material such as silicone resin. The first anti-slip member 161 includes a ring portion 169, a fitting protrusion 170, and an abutment protrusion 171.

The ring portion 169 is fitted into the suction nozzle body 160 from the holding unit 22 side in the axial direction. In addition, the first anti-slip member 161 is axially positioned with respect to the suction nozzle body 160 with the ring portion 169 abutting on the partition portion 167 in the axial direction.

A communication hole 169a is formed in the center of the ring portion 169. The communication hole 169a communicates the inside of the holding unit 22 and the inside of the suction nozzle body 160 through the through hole 168 described above.

The fitting protrusions 170 are formed at a position facing radially in the inner peripheral edge of the ring portion 169, and form a pair so as to sandwich the communication hole 169a therebetween. The fitting protrusion 170 protrudes from the ring portion 169 toward the side opposite to the holding unit 22 in the axial direction. Each fitting protrusion 170 is fitted into both ends of the through hole 168 in the radial direction. Thereby, the first anti-slip member 161 is positioned relative to the circumferential direction of the suction nozzle body 160. In this embodiment, the configuration in which the fitting protrusion 170 is fitted into the through hole 168 is described. However, the fitting protrusion 170 may be fitted in a hole other than the through hole 168.

The abutment protrusion 171 protrudes from the ring portion 169 toward the holding unit 22 side in the axial direction. The contact protrusion 171 is formed in a circular shape centered on the axis O. In this embodiment, the abutment protrusions 171 are formed as two concentric circles. In addition, the first anti-slip member 161 may not have the contact protrusion 171.

The second anti-slip member 162 is integrally formed of a resin material such as silicone resin. The second anti-slip member 162 is inserted into the suction nozzle body 160 from the side opposite to the holding unit 22 in the axial direction. In addition, the second anti-slip member 162 is positioned relative to the axial direction of the suction nozzle body 160 by abutting the partition 167 in the axial direction.

As shown in FIGS. 13 to 15, the peripheral wall 191b of the storage tank 191 is slightly closer to the bottom 191c than the opening 191a, and two engagement holes 198 are formed. The engaging hole 198 is used to fix the heater bracket 196 to the storage tank 191. The engaging hole 198 is formed to extend in the circumferential direction and has a rectangular shape when viewed from the radial direction. The two engaging holes 198 are arranged opposite to each other across the axis Q of the storage tank 191 side. In addition, in a state where the case 11 is housed in the transparent tube 121, the axis Q coincides with the axis O of the body unit 10. The axis Q constitutes an axis common to each part of the case 11. Hereinafter, the axis Q is not limited to the axis Q of the storage tank 191, but is also used for the description of each part constituting the cassette 11.

In addition, the peripheral wall 191b of the reservoir 191 is formed on the inner peripheral surface slightly deviated from the engagement hole 198 toward the opening 191a, and a guide recess 198a is formed. The guide recess 198a also opens toward the opening 191a side. The guide recess 198a has a function of guiding the engaging piece 206 described later when the heater bracket 196 is fixed to the storage tank 191.

The bottom portion 191c of the reservoir 191 is formed with a through hole 191d penetrating the bottom portion 191c at the center in the radial direction. An annular flow path tube 197 protruding from the inner surface of the bottom portion 191c to the inside of the storage tank 191 is integrally formed on the peripheral edge of the through hole 191d. Furthermore, the inside of the flow path tube 197 communicates with the through hole 191d. The flow path tube 197 is a flow path atomized into mist. The flow path tube 197 extends from the bottom 191c to be slightly closer to the opening 191a than the axial center of the reservoir 191.

Between the inner peripheral surface of the peripheral wall 191b and the outer peripheral surface of the flow channel tube 197, a plurality of (three in this embodiment) ribs 199 spanning between the peripheral wall 191b and the channel tube 197 are integrally formed. The ribs 199 are arranged at equal intervals in the circumferential direction so as to be radial when viewed from the axial direction. In addition, the rib 199 extends from the bottom 191c of the tank 191 to be flush with the end (front end) of the flow path tube 197 on the opening 191a side. The rib 199 is used to support the flow path tube 197.

The inner peripheral surface of the peripheral wall 191b is integrally formed with a convex portion 201 where the rib 199 is formed. The convex portion 201 extends in the axial direction so as to follow the rib 199. The convex portion 201 is formed from the bottom portion 191c of the storage tank 191 to the end portion (front end) of the rib 199 on the opening 191a side and the front end of the flow path tube 197. The convex portion 201 has the function of improving the mechanical strength of the storage tank 191 and the function of positioning the washer 192.

The washer 192 is formed so that its outer diameter is substantially the same as the inner diameter of the reservoir 191. The washer 192 performs positioning of the porous body 193 described later and maintains the posture of the porous body 193. In other words, the gasket 192 supports the porous body 193 described later. In the radial center of the gasket 192, an insertion hole 192a into which the flow path tube 197 can be inserted is formed. The gasket 192 is accommodated in the storage tank 191 so that the flow path tube 197 is inserted into the insertion hole 102a. In addition, the washer 192 is positioned in the storage tank 191 with one surface 192b abutting on the end surface 201a of the convex portion 201. In the state where the washer 192 is positioned, the outer peripheral surface of the washer 192 is in contact with the inner peripheral surface of the storage tank 191. Furthermore, the insertion hole 192a of the gasket 192 is in contact with the outer peripheral surface of the flow path tube 197.

A plurality of (four in this embodiment) openings 192c are formed in most of the space between the insertion hole 192a of the gasket 192 and the outer peripheral surface. The opening 192c is formed in an arc shape when viewed from the axial direction. The openings 192c are arranged at equal intervals in the circumferential direction. The spaces on both sides of the gasket 192 in the reservoir 191 are communicated through the opening 192c. A porous body 193 is arranged on the other surface 192d of the gasket 192 opposite to the one surface 192b.

The porous body 193 is a porous and liquid-absorbing member. The porous body 193 is formed of, for example, cotton fiber material. The porous body 193 is formed in substantially the same shape as the gasket 192. That is, the porous body 193 is also formed so that the outer diameter is substantially the same as the inner diameter of the storage tank 191. In the radial center of the porous body 193, an insertion hole 193a into which the flow path tube 197 is inserted is formed. The position of the porous body 193 is positioned by inserting the flow channel tube 197 into the insertion hole 193a and overlapping one surface 193b of the porous body 193 with the other surface 192d of the gasket 192. The outer peripheral surface of the porous body 193 is in contact with the inner peripheral surface of the storage tank 191. Furthermore, the insertion hole 193a of the porous body 193 is in contact with the outer peripheral surface of the flow path tube 197.

The inside of the storage tank 191 is partitioned by the porous body 193 into a liquid storage chamber 202 on the bottom 191c side and an opening chamber 203 on the opening 191a side. The liquid storage chamber 202 is a source of mist for storing liquid. The opening chamber 203 is a space for atomizing the mist gas source absorbed by the porous body 193.

The other surface 193c of the porous body 193 opposite to the one surface 193b is exposed in the opening chamber 203. The heating portion 194 is provided to be connected to the other surface 193c of the porous body 193 exposed in the opening chamber 203.

The heating portion 194 is used to atomize the mist source of the liquid. The heating unit 194 is housed in the opening chamber 203. The heating unit 194 includes a liquid-absorbent wick 204 formed in a substantially U-shape, and an electric heating wire 205 that heats the liquid-absorbent wick 204. The liquid absorbing core 204 is a porous and generally cylindrical member having liquid absorption properties. The liquid absorbing core 204 is bent into a substantially U-shape.

More specifically, the wick 204 is composed of two axially extending portions 204a extending axially and a radially extending portion 204c connecting one end of the two axially extending portions 204a to each other via a curved portion 204b. Furthermore, the other end of the axially extending portion 204a is connected to the porous body 193. By this, the mist source absorbed by the porous body 193 is sucked into the liquid absorbing core 204.

The heating wire 205 has a heating wire body 205a formed in a spiral shape around the radially extending portion 204c of the liquid absorbing core 204, and a heater holder 196 along the axial direction from both ends of the heating wire body 205a Two terminal portions 205b extending sideways. When the electric heating wire 205 heats the liquid-absorbent core 204, the mist gas source sucked into the liquid-absorbent core 204 will be atomized. The front ends of the two terminal portions 205b are folded back toward the porous body 193 side. The two terminal portions 205b are connected to the heater bracket 196.

Fig. 16 is a perspective view of the heater holder 196 viewed from the power supply unit 21 side (the first side in the axial direction).

As shown in FIGS. 13 and 16, the heater holder 196 is formed into a substantially cylindrical shape with a bottom. Furthermore, the opening 196a of the heater holder 196 is directed to the reservoir 191 side, and the opening 191a of the reservoir 191 is blocked.

The peripheral wall 196b of the heater holder 196 is formed so that the outer diameter is substantially the same as the outer diameter of the peripheral wall 191b of the storage tank 191. The outer peripheral surface of the peripheral wall 196b is formed from a substantially axial center to the opening 196a, and a reduced-diameter fitting portion 196d is formed across the stepped surface 196c. The fitting portion 196d is fitted to the inner peripheral surface of the peripheral wall 191b of the storage tank 191. In addition, the end of the peripheral wall 191b of the reservoir 191 on the opening 191a side abuts on the stepped surface 196c of the peripheral wall 196b. With this, the axial positioning of the heater bracket 196 of the storage tank 191 is performed.

In addition, the end of the fitting portion 196d on the opening 196a side is integrally formed with two engagement pieces 206 at positions corresponding to the two engagement holes 198 of the reservoir 191. The two engaging pieces 206 protrude toward the corresponding engaging holes 198. That is, the two engaging pieces 206 are arranged on both sides across the axis Q of the heater bracket 196.

The engaging piece 206 is engaged with the engaging hole 198 of the storage tank 191 to integrate the storage tank 191 and the heater bracket 196. The engaging piece 206 is formed to be elastically deformable in the radial direction. The front end of the engaging piece 206 protrudes outward in the radial direction with an engaging claw 207 formed with an engaging hole 198 that can be inserted into the reservoir 191.

The engaging claw 207 is formed so that the cross-sectional shape of the plane along the axial direction and the radial direction is substantially triangular. That is, the engagement claw 207 is configured such that the surface on the tip side thereof is an inclined surface 207a inclined toward the base end side (the fitting portion 196d side) as it goes radially outward. On the other hand, the flat surface 207b on the base end side of the engaging claw 207 is orthogonal to the axial direction.

In addition, the peripheral wall 196b of the heater holder 196 has a concave portion 208 aligned with the engaging claw 207 in the axial direction on the outer peripheral surface avoiding the fitting portion 196d. The recess 208 is directed radially outward And the stepped surface 196c side is opened. The concave portion 208 is formed with a first suction hole 209 penetrating the peripheral wall 196b in the thickness direction. The inner and outer systems of the peripheral wall 196b communicate with each other through the first suction hole 209.

Furthermore, the peripheral wall 196b of the heater holder 196 is formed with three engaging recesses 210 on the bottom 196e side. The three engagement recesses 210 are arranged at equal intervals in the circumferential direction (120° apart in the circumferential direction), and are arranged to avoid the formation position of the recess 208. The engaging recess 210 is formed to open radially outward and at the bottom 196e. On the bottom 196e side of the engagement recess 210, a beveled corner 210a in which the width of the engagement recess 210 in the circumferential direction gradually widens toward the bottom 196e is formed.

The vertical engagement convex portions 101 a to 101 c of each first coupling member 81 are inserted into the three engagement concave portions 210 formed in this way. Thereby, the heater holder 196 (casing 11) and the first coupling member 81 are coupled, and the heater holder 196 (casing 11) and the first coupling member 81 are positioned in the circumferential direction.

The bottom portion 196e of the heater holder 196 is integrally formed with a substantially plate-shaped connecting wall 211 that is upright from the inner surface in the axial direction. Furthermore, the connecting wall 211 extends along the radial direction of the axis Q passing through the heater holder 196, and both ends in the longitudinal direction of the radial direction are connected to the inner surface of the peripheral wall 196b. The connecting wall 211 divides the space in the heater bracket 196 into two parts.

Furthermore, the bottom 196e of the heater holder 196 is formed with two slits 212. The two slits 212 are arranged along both sides of the connecting wall 211 in the thickness direction.

Electrodes 213 and 214 are provided on both sides of the connecting wall 211 in the thickness direction. The electrodes 213 and 214 have: lead electrode portions 213a and 214a provided on the connection wall 211; and the lead electrode portions 213a and 214a are bent and extend to the bottom portion 196e through corresponding slits 212, respectively The outer connection electrode portions (planar electrodes) 213b and 214b. In addition, the two terminal portions 205b of the heating wire 205 constituting the heating portion 194 are connected to the respective lead electrode portions 213a and 214a.

The connection electrode portions 213b and 214b are formed in a substantially semicircular shape on both sides in the radial direction with the insulating portion 215 described later sandwiched therebetween. Specifically, when viewed from the axial direction, the two connecting electrode portions 213b and 214b are arranged such that the linear sides 213c and 214c face each other in the radial direction. In addition, when viewed from the axial direction, the arc-shaped edges 213d and 214d of the two connecting electrode portions 213b and 214b constitute an outer peripheral portion. Between the sides 213c and 214c of the two connection electrode portions 213b and 214b, the end portion with the connection wall 211 interposed therebetween. In a state where the heater holder 196 (casing 11) is connected to the first connecting member 81, the tip of the thimble electrode 49 (electrode body) held by each electrode holding portion 50 is in contact with each connecting electrode portion 213b, 214b. That is, the bottom portion 196e of the heater holder 196 functions as an electrode arrangement surface facing the base surface 91a in the axial direction with the casing 11 attached to the body unit 10.

Here, the connection electrode portions 213b and 214b are formed at least when the power supply unit 21 and the casing 11 relatively rotate about the axis O (axis Q) when the thimble electrode 49 (the first thimble electrode 49a and the second thimble electrode 49b) rotates On track. That is, each connection electrode portion 213b, 214b is formed to include a first imaginary circle C1 passing through the first thimble electrode 49a centered on the axis O and a second imaginary circle passing the second thimble electrode 49b centered on the axis O The area on both sides of the circle C2. In the present embodiment, since the thimble electrodes 49a and 49b are arranged in a line-symmetrical manner, the virtual circles C1 and C2 overlap.

Also, the end of the connecting wall 211 between the sides 213c, 214c of the two connecting electrode portions 213b, 214b extends along the radial direction passing through the axis Q of the heater holder 196, in other words, the connecting wall 211 Set on an imaginary straight line T1 connecting two thimble electrodes 49 The imaginary straight line T1 in the predetermined direction. This predetermined direction coincides with an imaginary straight line T2 passing through the center of the circumferential direction of one of the three engagement recesses 210 formed in the heater bracket 196 and the axis Q of the heater bracket 196. The width of the connecting wall 211 in the short side direction (the circumferential direction around the axis Q) is formed to be slightly larger than the axial diameter of each thimble electrode 49.

The end portion of the connecting wall 211 arranged in this way functions as an insulating portion 215 that partitions the connecting electrode portions 213b and 214b in the circumferential direction. The insulating portion 215 is arranged on an imaginary straight line T2 passing through the circumferential center of the one engaging recess 210 and the axis Q of the heater holder 196, whereby the heater holder 196 (casing 11) and the first connecting member 81 face each other In the connected state, the tip of each thimble electrode 49 is surely in contact with the two connection electrode portions 213b and 214b, respectively. In other words, there will be no situation where the two thimble electrodes 49 are in contact with one of the two connection electrode portions 213b, 214b at the same time. As described above, the connection electrode portions 213b and 214b of the present embodiment are formed on both sides in the radial direction of the virtual straight line T2 (insulating portion 215), and are formed to include virtual circles C1 and C2 with respect to the virtual circle C1. , C2 expands to a semicircular shape on the radially outer side (arc sides 213d, 214d) and the inner side (sides 213c, 214c).

Further, the arc sides 213d and 214d of the two connecting electrode portions 213b and 214b are formed approximately at the center in the circumferential direction, and concave portions 213e and 214e which are recessed radially inward are formed. Among the bottom portions 196e of the heater holder 196 corresponding to the recesses 213e and 214e connecting the electrode portions 213b and 214b, a second air intake penetrating in the thickness direction of the bottom portion 196e is formed at a portion corresponding to one recess 213e孔216. The inner and outer parts of the bottom 196e communicate with each other through the second suction hole 216.

In addition, the bottom portion 196e corresponds to the connection electrode portions 213b and 214b, and has a concave portion 196f having the same shape as the connection electrode portions 213b and 214b when viewed from the axial direction. even The contact electrode portions 213b and 214b are accommodated in this concave portion 196f. By forming the concave portion 196f, the surface of the connection electrode portions 213b, 214b and the surface of the bottom portion 196e where the two connection electrode portions 213b, 214b are not disposed are on the same plane. A part of the atomizing container 195 is housed so as to be fitted on the inner peripheral surface of the peripheral wall 196b of such a heater holder 196.

As shown in FIG. 11, in a state where the cassette body 11 is attached in the holding unit 22, the outer peripheral portion of the bottom portion 196 e abuts on the surrounding convex portion 93 in the axial direction. Therefore, the space enclosed by the bottom portion 196e and the connection cover 80 (the base surface 91a and the surrounding convex portion 93) forms a buffer space S3 that allows the communication port 51 to communicate with the second suction hole 216. In the example of FIG. 11, the communication port 51 and the second suction hole 216 are arranged at positions separated in the axial direction and shifted in the circumferential direction. In addition, the communication port 51 and the second suction hole 216 may be disposed at positions offset in the radial direction.

The communication port 51 of this embodiment communicates into the flow path tube 197 through the buffer space S3, the second suction hole 216, and the like. In addition, in the bottom portion (second surface) 196e, a portion around the convex portion 93 abutting is formed as a flat surface orthogonal to the axial direction. In the bottom portion 196e, the portion that abuts on the convex portion 93 may be a convex surface, a concave surface, an inclined surface, or the like.

In this embodiment, the casing 11 is pressed by the suction nozzle 23 around the convex portion 93, and is in close contact with the bottom 196e in an elastically deformed state. However, the surrounding convex portion 93 and the bottom portion 196e are not necessarily in close contact but may be separated. That is, if negative pressure can be generated in the pressure fluctuation chamber S1 through the communication port 51 during suction, there may be a slight gap between the surrounding convex portion 93 and the bottom portion 196e.

FIG. 17 is a perspective view of the atomizing container 195 viewed from the porous body 193 side (second side in the axial direction).

The atomizing container 195 shown in FIGS. 13, 14 and 17 is an elastic member and is formed of a resin material such as silicone resin. The atomizing container 195 is set in the axial direction Between the other surface 193c of the porous body 193 and the vicinity of the bottom 196e of the heater holder 196. That is, the atomizing container 195 is formed in a substantially cylindrical shape surrounding the heating portion 194, and integrally formed with the cylindrical portion 217 fitted to the inner peripheral surface of the peripheral wall 191b of the storage tank 191, and fitted to the heating The inner peripheral surface of the peripheral wall 196b of the device holder 196 is a substantially block-shaped fitting portion 218.

The end portion of the cylindrical portion 217 on the porous body 193 side is formed with a stepped surface 217a at most of the radial center. By forming the stepped surface 217a, an annular protruding portion 219 in which the outer peripheral portion of the cylindrical portion 217 protrudes toward the porous body 193 side is formed. The end of the protruding portion 219 abuts on the other surface 193c of the porous body 193. The outer diameter of the protrusion 219 is approximately the same as or slightly smaller than the inner diameter of the peripheral wall 191b of the reservoir 191.

Most of the stepped surface 217a corresponds to the shape of the heating portion 194, and a storage recess 220 is formed. The storage recess 220 is an atomization chamber M that stores the mist atomized by the heating unit 194. The atomizing chamber M is in communication with the flow channel 197 of the storage tank 191.

The storage recess 220 is formed with a seating surface 221 on which the curved portion 204b of the liquid wick 204 constituting the heating portion 194 is placed. The radially inner surface of the seat surface 221 is formed with a concave portion 221 a so as not to interfere with the terminal portion 205 b of the electric heating wire 205 constituting the heating portion 194.

A sealing portion 222 is formed on the outer peripheral surface of the cylindrical portion 217 near the fitting portion 218. The sealing portion 222 is formed to protrude outward in the radial direction around the entire circumference except for the notch portion 222a described later. The sealing portion 222 has the function of ensuring the sealing between the cylindrical portion 217 and the peripheral wall 191b of the storage tank 191, and the function of suppressing the atomization container 195 from falling off from the storage tank 191.

The outer diameter of the sealing portion 222 is slightly larger than the inner diameter of the peripheral wall 191b of the reservoir 191. Therefore, in a state where the atomizing container 195 is stored in the storage tank 191, the sealing portion 222 is compressed in the radial direction. Thereby, the sealing property of the sealing portion 222 can be ensured, and the frictional resistance of the sealing portion 222 can prevent the atomizing container 195 from falling off from the storage tank 191.

In addition, the sealing portion 222 is formed with two notch portions 222a. The two notch portions 222a are arranged facing each other across the axis Q of the storage tank 191. The notch portion 222a allows the outside air to communicate with the liquid accumulation portion 223 described later.

The outer peripheral surface of the cylindrical portion 217 is connected between the front end of the protruding portion 219 and the sealing portion 222, and a liquid accumulating portion 223 is formed. The liquid accumulation part 223 is temporarily accumulated when the porous body 193 and the wick 204 are saturated, and the mist source of the liquid stored in the liquid storage chamber 202 of the storage tank 191 leaks through the inner peripheral surface of the peripheral wall 191b of the storage tank 191. The location of the leaking mist source.

The liquid accumulating portion 223 forms the entire outer peripheral surface of the cylindrical portion 217 so that the gap between the outer peripheral surface of the cylindrical portion 217 and the peripheral wall 191b of the reservoir 191 gradually narrows from the sealing portion 222 toward the front end of the protruding portion 219. A concave portion formed by inclining. In other words, the liquid accumulating portion 223 is a concave portion where the gap between the outer peripheral surface of the cylindrical portion 217 and the peripheral wall 191b of the reservoir 191 gradually widens toward the opening 191a of the reservoir 191. Since such a liquid accumulating portion 223 is formed, a narrow portion 279 that forms a minute gap between the protruding portion 219 and the peripheral wall 191 b of the reservoir 191 is formed near the protruding portion 219 of the cylindrical portion 217.

Here, the end of the protruding portion 219 of the cylindrical portion 217 abuts on the other surface 193c of the porous body 193. Moreover, the outer peripheral surface of the porous body 193 is in contact with the inner peripheral surface of the storage tank 191. Therefore, the narrow portion 279 formed between the protruding portion 219 of the cylindrical portion 217 and the peripheral wall 191b of the reservoir 191 is covered (closed) by the outer peripheral portion of the porous body 193.

In addition, the outer peripheral surface of the cylindrical portion 217 is formed on the heater holder 196 side of the sealing portion 222 at a position corresponding to the engaging piece 206, and a recess for receiving the engaging piece 206 is formed 部224. By inserting the engaging piece 206 into the concave portion 224, the atomizing container 195 and the heater holder 196 are positioned in the circumferential direction. In addition, the bottom surface 224 a of the concave portion 224 of the cylindrical portion 217 abuts on the inner surface in the radial direction inside of the engaging piece 206.

The fitting portion 218 of the atomizing container 195 is formed in a substantially cylindrical shape that can be fitted to the inner peripheral surface of the peripheral wall 196b of the heater holder 196. That is, the fitting portion 218 is formed with a stepped portion 217b to reduce the outer diameter from the outer diameter of the cylindrical portion 217. The fitting portion 218 is formed with a slit 225 into which the connecting wall 211 of the heater bracket 196 can be inserted. In addition, the fitting portion 218 is also formed with a slit for a heating wire (not shown) that communicates with the slit 225 and into which the terminal portion 205 b of the heating wire 205 can be inserted. The terminal portion 205b of the electric heating wire 205 is inserted into the slit for the electric heating wire, and the terminal portion 205b is held in the atomizing container 195. Then, the lead electrode portions 213a and 214a provided in the connection wall 211 are connected to the terminal portion 205b of the heating wire 205.

In addition, the fitting portion 218 is formed at a position corresponding to the first air intake hole 209 and the second air intake hole 216 of the heater holder 196, and an air passage 226 is also formed. In addition, the fitting portion 218 is formed with a slit 225 and a slit 218 a in which the air passage 226 communicates with the atomizing chamber M (storage recess 220) of the cylindrical portion 217. The ventilation path 226 communicates with the atomization chamber M (storage recess 220) of the atomization container 195 through the slit 218a. Therefore, the atomization chamber M (storage recess 220) of the atomization container 195 communicates with the first air intake hole 209 and the second air intake hole 216 of the heater holder 196 through the air passage 226 and the slit 218a.

<Assembly structure of the whole taster>

Figure 18 is a front view of the taster 1.

As shown in FIG. 18, the main body unit 10 of the taster 1 is provided with a connecting portion that connects the power supply unit 21, the holding unit 22, and the suction nozzle 23 along the axial direction extending along the axis O (center axis) 300. The connection part 300 has a first rotation connection part 301 connecting the power supply unit 21 and the holding unit 22 and a second rotation connection part 302 connecting the holding unit 22 and the suction nozzle 23.

In the following description, when the power supply unit 21 side is viewed from the suction nozzle 23 side along the axis O, the direction rotating clockwise around the axis O among the circumferential directions around the axis O is referred to as the rotation direction M1, The direction of turning counterclockwise around the axis O is called the turning direction M2.

The first rotation connection portion 301 is for connecting and disconnecting the power supply unit 21 and the holding unit 22 by relative rotation of the power supply unit 21 and the holding unit 22 about the axis O. When the power supply unit 21 is used as a reference, the holding unit 22 is rotated relative to the power supply unit 21 in the direction of rotation M1, and the power supply unit 21 and the holding unit 22 are connected to rotate the holding unit 22 relative to the power supply unit 21 in the direction of rotation M2. The connection between the unit 21 and the holding unit 22 is released.

The first rotation connection portion 301 includes a rotation connection mechanism 310 constituted by the first connection member 81 and the second connection member 122 shown in FIG. 9 above, and the one shown in the above FIGS. 9 and 10 The lock mechanism 311 constituted by the ring-shaped piece 82 and the second coupling member 122. Specifically, as shown in FIG. 9, the rotation connection mechanism 310 inserts the lateral engagement convex portion 102 of the first connection member 81 provided in the power supply unit 21 into the second connection member 122 provided in the holding unit 22 in the axial direction After engaging the groove 158, the holding unit 22 is rotated with respect to the power supply unit 21 in the rotation direction M1 (see FIG. 18), so that the horizontal engagement convex portion 102 is locked to the locking piece 142, so that the power supply unit 21 Connected to the holding unit 22.

The lock mechanism 311 restricts the rotation of the holding unit 22 in the rotation direction M2 that releases the connection caused by the rotation connection mechanism 310. Specifically, as shown in FIGS. 9 and 10, the lock mechanism 311 is provided with an annular piece 82 provided on the power supply unit 21, The flexure 106 protruding outward in the radial direction; and the second coupling member 122 provided in the holding unit 22 protrude inward in the radial direction relative to the bottom of the engaging piece 142 relative to the bottom of the engaging recess 155. The front end portion 142 a of the locking piece 142 is located on the movement path of the flexure 106 around the axis O.

When the rotation connection mechanism 310 is connected (when the holding unit 22 is rotated in the rotation direction M1 relative to the power supply unit 21), the flexure 106 contacts the front end 142a of the catch piece 142, and the flexure 106 is directed radially inward It elastically deforms and passes over the tip portion 142a. After passing through the front end portion 142a, the flexure 106 rebounds and deforms radially outward and engages with the engagement recess 155. When the flexure 106 is engaged with the engagement recess 155, the flexure 106 is opposed to the front end 142 a of the locking piece 142 in the rotation direction M1 and is caught. Therefore, the connection between the power supply unit 21 and the holding unit 22 cannot be released without applying a certain level of force.

According to the first rotary connection portion 301, in order to improve manufacturing efficiency and the like, as in the present embodiment, even when the power supply unit 21 and the holding unit 22 are separable, it is possible to achieve the power supply unit 21 and the holding by the rotary connection mechanism 310 The connection of the unit 22 is facilitated, and the reliability (connection strength) of the connection state of the power supply unit 21 and the holding unit 22 is improved by the lock mechanism 311. In addition, the connection by the rotation connection mechanism 310 and the locking by the locking mechanism 311 are also performed, so that the usability of assembly can be improved.

In the lock mechanism 311, as shown in FIG. 10, the elastically deformed flexure 106 is disposed radially inward of the buckle piece 142 having a material layer thicker than the ring piece 82 and having a higher rigidity. Therefore, in a state where the power supply unit 21 and the holding unit 22 are connected, the flexure 106 is covered and protected from the outside by the latching piece 142. Therefore, even if there is a fall, impact, etc., the flexure 106 damage will also be reduced. Therefore, the strength for repeated assembly use can be ensured, and the reliability of locking can also be improved.

As shown in FIG. 9, the engaging piece 142 engaged by the flexure 106 is formed with an engaging groove 158 for engaging the lateral engaging convex portion 102 of the rotation connection mechanism 310. Therefore, the latching piece 142 not only forms a part of the rotation connection mechanism 310 (engagement groove 158), but also forms a part of the lock mechanism 311 (front end portion 142a (convex portion)), so it is easier to improve the reliability of the connection state ( Connection strength).

As shown in FIG. 18, the second rotation connection portion 302 connects and disconnects the holding unit 22 and the suction nozzle 23 by relative rotation of the holding unit 22 and the suction nozzle 23 about the axis O. When the holding unit 22 is used as a reference, the suction nozzle 23 is rotated in the rotation direction M1 relative to the holding unit 22, and the holding unit 22 and the suction nozzle 23 are connected. In addition, the suction nozzle 23 is rotated in the rotation direction M2 relative to the holding unit 22, and the connection between the holding unit 22 and the suction nozzle 23 is released.

As shown in FIG. 11 above, the second rotary connection portion 302 includes a male screw portion 160a provided in the suction nozzle 23 and a female screw portion 123a provided in the holding unit 22. Specifically, the second rotation connecting portion 302 rotates the male screw portion 160a provided in the suction nozzle 23 with respect to the female screw portion 123a provided in the holding unit 22 in the direction of rotation M1 to rotate the holding unit 22 It is connected to the suction nozzle 23. Then, by rotating the male screw portion 160a provided in the suction nozzle 23 relative to the female screw portion 123a provided in the holding unit 22 in the rotation direction M2, the connection between the holding unit 22 and the suction nozzle 23 is released.

As shown in FIG. 18, the rotation direction M1 is not only the connection direction with respect to the holding unit 22 of the power supply unit 21, but also the connection direction with respect to the suction nozzle 23 of the holding unit 22 to. In addition, the rotation direction M2 is not only the direction of disconnection relative to the holding unit 22 of the power supply unit 21 but also the direction of disconnection relative to the suction nozzle 23 of the holding unit 22. In this way, in the first rotation connection portion 301 and the second rotation connection portion 302, the rotation directions of the connection and disconnection around the axis O are the same. Therefore, it is possible to give the user a sense of unity in assembling the unit and improve the usability.

The frequency of releasing the connection between the suction nozzle 23 and the holding unit 22 for replacement of the cartridge 11 is higher than the frequency of releasing the connection between the power supply unit 21 and the holding unit 22. The present embodiment is designed such that: in the first rotation connection portion 301, a first torque 301T is applied around the axis O to release the connection between the power supply unit 21 and the holding unit 22, and in the second rotation connection portion 302, the first rotation is applied The second torque 302T with a smaller moment 301T releases the connection between the holding unit 22 and the suction nozzle 23. Therefore, it is possible to prevent the holding nozzle 22 from rotating together with the power supply unit 21 when the suction nozzle 23 is detached from the holding unit 22.

The first torque 301T is the peak value of the torque value when the power supply unit 21 rotates the holding unit 22 in the direction of rotation M2, and corresponds to the radial elastic deformation of the flexure 106 shown in FIGS. 9 and 10 The elastic coefficient is related. The second torque 302T is the peak value of the torque value when the suction nozzle 23 is rotated in the rotation direction M2 with respect to the holding unit 22, and the static friction force between the male screw portion 160a and the female screw portion 123a shown in FIG. related. In addition, the first torque 301T may be, for example, 1.5 times or more the second torque 302T.

Since the first rotating connection portion 301 and the second rotating connection portion 302 have different connection structures, it is easy to adjust the magnitude relationship between the first torque 301T and the second torque 302T. For example, when the material of the flexure 106 (ring-shaped piece 82) forming the lock mechanism 311 of the first rotary connection 301 is selected and the thickness is adjusted, the elasticity corresponding to the radial direction of the flexure 106 can be changed The elastic coefficient of elastic deformation can easily adjust the magnitude of the first torque 301T relative to the second torque 302T.

FIG. 19 is a cross-sectional view along the axial direction when the suction nozzle 23 is removed from the taste absorber 1.

As shown in FIG. 19, in the taster 1, the suction nozzle 23 is detached from the body unit 10, and the cartridge body 11 can be attached and detached in the axial direction. The portion where the suction nozzle 23 is detached from the main body unit 10 is referred to as a cassette housing portion 320. That is, the box housing portion 320 includes the holding unit 22 and the power supply unit 21.

The box housing portion 320 is formed with a bottomed box housing space 321. The peripheral wall of the box storage portion 320 forming the box storage space 321 is formed by the holding unit 22. In addition, the bottom of the box storage portion 320 forming the box storage space 321 is formed by the power supply unit 21. That is, the peripheral wall (holding unit 22) of the box storage portion 320 can be detachable with respect to the bottom of the box storage portion 320 (power supply unit 21 ).

The bottom of the cassette housing portion 320 is provided with a vertical engagement convex portion 101 provided on the first coupling member 81 in the axial direction (the symbols of the vertical engagement convex portions 101a to 101c are shown in the figures after FIG. 19 and after For 101). The longitudinal engagement convex portion 101 is arranged so as to be able to be inserted into the engagement concave portion 210 provided in the casing 11 in the axial direction. That is, the longitudinal engagement convex portion 101 and the engagement concave portion 210 are arranged on the same radius with the axis O as the center. The longitudinal engagement convex portion 101 and the engagement concave portion 210 form a first rotation restricting portion 330 that restricts the relative rotation of the case 11 relative to the case receiving portion 320 (the case receiving space 321) about the axis O.

In the first rotation restricting portion 330, when the casing 11 and the casing accommodating portion 320 relatively rotate about the axis O, the longitudinal engagement convex portion 101 provided on the same radius is inserted into the engagement concave portion 210 to perform the winding of the casing 11 Limitation of axis O rotation. With this, the circumferential position of the casing 11 is fixed To ensure electrical connection between the connecting electrode portions 213b and 214b (see FIG. 10) of the bottom portion 196e of the casing 11 and the thimble electrode 49 of the power supply unit 21.

The first rotation restricting portion 330 forms a positioning mechanism 340 together with the suction nozzle 23, and the positioning mechanism 340 is screwed with the suction nozzle 23 relative to the cassette housing portion 320 (holding unit 22) to make the cassette 11 It is positioned relative to the cassette housing 320. According to this positioning mechanism 340, the positioning of the casing 11 can be performed simultaneously with the screwing of the suction nozzle 23 with respect to the casing accommodating portion 320. Therefore, the positioning of the cartridge 11 that can be attached to and detached from the cartridge housing portion 320 becomes easy, and the complexity of assembly is eliminated. In addition, there is no need to directly turn the cassette body 11 by hand.

Specifically, the suction nozzle 23 is provided with the above-mentioned first anti-slip member (cassette contact portion) 161 that rotates the cassette 11 about the axis O with respect to the cassette housing portion 320. The first anti-slip member 161 is attached to the suction nozzle body 160 and abuts against the cartridge 11 while the suction nozzle body 160 is connected to the holding unit 22. When the first anti-slip member 161 abuts on the cassette body 11, the cassette body 11 starts to rotate together with the suction nozzle 23, and when the circumferential positions of the engaging concave portion 210 and the vertical engaging convex portion 101 coincide, the cassette body 11 will sink to the bottom side of the case accommodating portion 320 due to gravity, so that the vertical engagement convex portion 101 is inserted into the engagement concave portion 210 to position the case 11 in the circumferential direction.

In addition, when the suction nozzle 23 is locked, the first anti-slip member 161 is compressed in the axial direction between the casing 11 and the suction nozzle body 160 supported by the power supply unit 21 (vertical engagement convex portion 101, etc.) . As shown in FIG. 11, the first anti-slip member 161 presses the cartridge 11 toward the power supply unit 21 with the suction nozzle 23 screwed to the holding unit 22. With this, the axial positioning of the casing 11 is performed.

The first anti-slip member 161 is formed of polysiloxane resin as described above, so it is easy to generate frictional force to rotate the casing 11 in the circumferential direction and to press the casing 11 in the axial direction The pressure. In addition, as shown in FIG. 19, the first anti-slip member 161 is formed with an abutment protrusion 171 on the facing surface 161 a facing the case 11. By contacting the protrusion 171, the contact between the first anti-slip member 161 and the case 11 is not in surface contact, so if the contact pressure increases, it will be easier to generate circumferential frictional force and axial pressing force.

Also, as shown in FIG. 11, when the contact protrusion 171 is crushed in the axial direction, the gap between the through hole 191d of the case 11 and the communication hole 169a of the first anti-slip member 161 is hermetically sealed. The body 11 communicates with the flow path of the suction nozzle 23, and the mist generated in the cartridge 11 can be sucked through the suction nozzle 23. Since the contact protrusion 171 is formed in a double ring shape (see FIG. 12), a double seal with high airtightness can be formed.

As shown in FIG. 19, the suction nozzle 23 is provided with a second rotation restricting portion 350 that restricts the relative rotation of the first anti-slip member 161 relative to the suction nozzle body 160. The second rotation restricting portion 350 is formed by the fitting protrusion 170 (refer to FIG. 12) provided at the first anti-slip member 161 and the elongated through hole 168 (refer to FIG. 12) provided at the suction nozzle body 160 form. The fitting protrusions 170 extend a pair in the axial direction toward the suction nozzle body 160 and are fitted to both ends of the through hole 168 in the longitudinal direction.

According to the second rotation restricting portion 350, even if condensed mist stays between the suction nozzle body 160 and the first anti-slip member 161, the idling of the first anti-slip member 161 relative to the suction nozzle body 160 can be prevented ( slide). Therefore, the positioning of the casing 11 in the circumferential direction can be surely performed. In addition, the through hole 168 may be formed as a long hole and integrated with the suction port 23a.

<Assembly method of sucker>

Next, a method of assembling the above-mentioned taste absorber 1 will be described.

As shown in FIG. 2, when assembling the taste absorber 1 of this embodiment, first, the holding unit 22 is assembled to the power supply unit 21. Specifically, after inserting the lateral engagement convex portion 102 into the engagement groove 158 in the axial direction, the power supply unit 21 and the holding unit 22 are relatively rotated about the axis O. In this way, the power supply unit 21 and the holding unit 22 are combined in the axial and circumferential directions with the first rotary connection portion 301 positioned. In addition, when the power supply unit 21 and the holding unit 22 are disassembled, an operation opposite to the above operation is performed.

Next, the cartridge 11 is inserted into the holding unit 22. Specifically, the case 11 is inserted into the holding unit 22 with the connection electrode portions 213b and 214b of the case 11 facing the holding unit 22 side in the axial direction. When the longitudinal engagement convex portions 101 a to 101 c of the power supply unit 21 and the circumferential position of the engagement concave portion 210 of the case 11 coincide, the respective longitudinal engagement convex portions 101 a to 101 c are inserted into the corresponding engagement concave portions 210. The engaging concave portion 210 is formed with a beveled portion 210a, and on the other hand, the front end of the vertical engaging convex portions 101a to 101c is formed with an inclined surface. Therefore, the vertical engagement convex portions 101a to 101c can be smoothly inserted into the engagement concave portion 210. Thereby, the circumferential direction and the axial direction of the casing 11 of the power supply unit 21 are positioned, and the casing 11 is attached to the regular position of the power supply unit 21.

That is, one of the thimble electrodes 49 of the power supply unit 21 is connected to one of the connection electrode portions 213 b and 214 b of the connection electrode portions 213 b and 214 b of the casing 11, and the other thimble electrode 49 is connected to the casing 11 Of the connecting electrode portions 213b and 214b, the other connecting electrode portions 213b and 214b are connected. The power of the power supply unit 21 can be supplied to the heating wire 205 of the heating unit 194 through the connection electrode portions 213b, 214b (electrodes 213, 214). In addition, the bottom portion 196e of the casing 11 abuts on the surrounding convex portion 93 to partition the buffer space S3 by the casing 11 and the connection cover 80.

Next, the suction nozzle 23 is assembled to the holding unit 22 using the above-mentioned second rotating connection portion 302. Specifically, the male screw portion 160a of the suction nozzle body 160 is locked to the female screw portion 123a of the sleeve 123. In this way, the first anti-slip member 161 of the suction nozzle 23 is in contact with the bottom 191c of the casing 11. In this state, when the suction nozzle 23 is further locked, the first anti-slip member 161 is elastically deformed, pressing the cartridge 11 toward the power supply unit 21 side in the axial direction, and holding the cartridge 11 in the holding unit 22 in this state Inside. In addition, the case 11 is restricted from moving in the circumferential direction with respect to the power supply unit 21 by the vertical engagement convex portions 101 a to 101 c. Therefore, the frictional force acting between the first anti-slip member 161 and the casing 11 prevents the casing 11 from rotating together with the suction nozzle 23.

Next, the tobacco capsule 12 is inserted into the suction nozzle 23. Specifically, the tobacco capsule 12 is fitted into the suction nozzle body 160 with the mesh opening facing the suction nozzle 23.

At this point, the assembly of the taste absorber 1 is completed.

In addition, when the case 11 is inserted, along with the circumferential direction of the case 11, the circumferential engagement positions 101 a to 101 c of the power supply unit 21 and the circumferential position of the engagement recess 210 of the case 11 do not match. Situation. In this case, the bottom 196e of the case 11 is superposed on the vertical engagement convex portions 101a to 101c (hereinafter referred to simply as "stacked state").

FIG. 20 is an explanatory diagram showing a state where the cassette body 11 is stacked on the vertical engagement convex portion 101. FIG.

As shown in FIG. 20, the stacked state of the casing 11 restricts the movement of the casing 11 relative to the power supply unit 21 in the axial direction of the power supply unit 21 side. Therefore, the thimble electrode 49 and the connection electrode portions 213b and 214b are axially separated, and the conduction between the power supply unit 21 and the casing 11 cannot be ensured. In the stacked state, even if the thimble electrode 49 is in contact with the connection electrode portions 213b and 214b, There is a possibility that the thimble electrode 49 and the connection electrode portions 213b and 214b are not arranged at a desired circumferential position.

FIG. 21 is an explanatory diagram showing how the suction nozzle 23 is locked when the cassette 11 is stacked.

As shown in FIG. 21, when the rotating suction nozzle 23 is locked to the holding unit 22 in the stacked state of the case 11, as shown in FIG. 22 described later, at least before the locking, the first anti-slip member 161 is Would be in contact with the box 11. Specifically, as shown in FIG. 21, when the male screw portion 160a of the suction nozzle 23 locks the female screw portion 123a of the holding unit 22, the first anti-slip member 161 has not yet contacted the case 11, However, as shown in FIG. 22, when the male screw portion 160a locks the female screw portion 123a half a turn to about one or two turns, the first anti-slip member 161 abuts the case 11.

FIG. 22 is an explanatory diagram showing how the suction nozzle 23 and the casing 11 rotate together.

As shown in FIG. 22, when the first anti-slip member 161 is in contact with the case 11, when the locking operation of the suction nozzle 23 is continued, it will act on the first anti-slip member 161 and the case 11. The frictional force between them causes the suction nozzle 23 to rotate together with the casing 11. That is, by the locking operation of the suction nozzle 23, the casing 11 is pushed toward the power supply unit 21 side in the axial direction, and rotates in the circumferential direction (locking direction (rotation direction M1)).

Then, when the circumferential positions of the engagement recesses 210 of the case 11 and the longitudinal engagement protrusions 101a to 101c of the power supply unit 21 become coincident, the longitudinal engagement protrusions 101a to 101c enter the corresponding engagement recesses 210 Inside. That is, the axial movement of the cartridge 11 relative to the power supply unit 21 is allowed, so that the cartridge 11 is assembled to a regular position. Therefore, it becomes In a state where movement in the circumferential direction of the power supply unit 21 is restricted, the thimble electrode 49 is in contact (conduction) with the connection electrode portions 213b and 214b.

FIG. 23 is an explanatory diagram showing how the suction nozzle 23 is locked to the end.

As shown in FIG. 23, when the circumferential positioning of the vertical engaging convex portion 101 and the engaging concave portion 210 allows the axial movement of the cassette 11, the suction nozzle 23 can be further locked. When the suction nozzle 23 is locked to the end, the connecting electrode portions 213b and 214b will press against the ejector pin electrode 49, and at the same time, the first anti-slip member 161 is between the casing 11 supported by the power supply unit 21 and the suction nozzle body 160 Compressed in the axial direction, the cartridge body 11 is positioned in the axial direction. Therefore, by locking the suction nozzle 23, positioning of the casing 11 in the circumferential direction and the axial direction, and electrical conduction between the casing 11 and the power supply unit 21 can be performed. In addition, since the abutment protrusion 171 of the first anti-slip member 161 is compressed in the axial direction, the gap between the casing 11 and the suction nozzle 23 can be sealed.

In addition, as described above, when the case 11 is assembled to a regular position, the surrounding convex portion 93 of the connection cover 80 is in contact with the case 11. Therefore, a buffer space S3 (see FIG. 3) surrounded by the surrounding convex portion 93 is formed between the bottom 196 e of the heater bracket 196 of the casing 11 and the connection cover 80.

<Assembly method of case>

Next, a method of assembling the above-mentioned case 11 will be described.

First, the liquid mist chamber 202 of the storage tank 191 is filled with a mist source of liquid, and then the gasket 192 and the porous body 193 are sequentially loaded from the opening 191 a of the storage tank 191. At this time, the one surface 192b of the washer 192 is brought into contact with the end surface 201a of the convex portion 201 of the reservoir 191. Then, one side 193b of the porous body 193 overlaps the other side 192d of the gasket 192. Therefore, by storing the porous body 193 The space in the groove 191 is just divided into the liquid storage chamber 202 and the opening chamber 203. Although the porous body 193 itself is soft, the posture can be maintained and positioned by the washer 192.

In addition, in parallel with the above process, the heating unit 194 and the atomizing container 195 are assembled to the heater holder 196. Specifically, first, the heating portion 194 is assembled into the storage recess 220 of the atomizing container 195. Next, the fitting portion 218 side of the atomizing container 195 is directed toward the opening 196 a of the heater holder 196, and the atomizing container 195 is inserted into the heater holder 196. Then, the fitting portion 218 is fitted to the inner peripheral surface of the peripheral wall 196b of the heater holder 196. At this time, the connection wall 211 of the heater holder 196 is aligned with the direction of the slit 225 of the fitting portion 218, and the connection wall 211 is inserted into the insertion slit 225.

Next, the heater bracket 196 is attached to the opening 191a of the storage tank 191. Specifically, the engaging piece 206 side of the heater bracket 196 is opposed to the opening 191a side of the reservoir 191, and the heater bracket 196 is inserted into the opening 191a of the reservoir 191. At this time, the positions of the engaging holes 198 and the guide recess 198a formed in the peripheral wall 191b of the storage tank 191 and the engaging piece 206 of the heater holder 196 are also aligned.

When the heater holder 196 is inserted into the opening 191a of the reservoir 191 in this state, first, the inclined surface 207a of the engagement claw 207 formed in the engagement piece 206 abuts on the peripheral wall 191b of the reservoir 191. With the inclined surface 207a, the engaging claw 207 smoothly abuts on the guide recess 198a of the reservoir 191.

Then, when the heater holder 196 is further pressed into the reservoir 191, the engaging claw 207 enters the guide recess 198a. In addition, the engaging piece 206 is elastically deformed by being pushed radially inward by the guide recess 198a. At this time, due to the inclined surface 207a of the engaging claw 207, the engaging piece 206 smoothly elastically deforms radially inward. Here, because the two engaging pieces 206 are separated by the axis Q and Since they are arranged oppositely on both sides, the force acting on the radially inner side of the two engaging pieces 206 is not easily deviated from the whole of the heater bracket 196. Therefore, it is easy to achieve a balance of forces when elastically deforming the engaging piece 206, and the heater holder 196 can be easily inserted into the opening 191a of the storage tank 191. In addition, the bottom surface 224 a of the concave portion 224 of the atomization container 195 abuts on the inner surface in the radial direction of the engagement piece 206. Therefore, when the engaging piece 206 is elastically deformed radially inward, the concave portion 224 of the atomizing container 195 is slightly deformed radially inward.

Then, when the heater holder 196 is further pressed in, the engaging claw 207 moves along the guide recess 198a. Then, the engaging claw 207 crosses the end of the guide recess 198a (the end of the reservoir 191 on the engaging hole 198 side), and then by the restoring force of the engaging piece 206 and the restoring force of the recess 224 of the atomizing container 195 , The engaging claw 207 is inserted into the engaging hole 198 of the storage tank 191. In this way, the heater bracket 196 is fixed to the storage tank 191, and the assembly of the casing 11 is completed.

Here, in a state where the heater bracket 196 is fixed to the storage tank 191, the peripheral wall 191 b of the storage tank 191 covers the radially outer surface of the engaging piece 206. In addition, if one of the two engaging claws 207 is to be disengaged, for example, when the storage tank 191 or the heater bracket 196 is tilted to disengage the engaging claw 207 from the engaging hole 198, the other side The engaging claw 207 is pressed radially outward. Therefore, once engaged, it is difficult to disengage the engagement hole 198 and the engagement piece 206.

<How to use the sucker>

When using the above-mentioned tasting device 1, the user presses the button 78. At this time, for example, the button 78 is pressed multiple times (for example, five times) to cause the switching element 52 to output a start preparation signal to the control unit mounted on the first substrate module 34.

Next, the user sucks while holding the suction nozzle 23 or the tobacco capsule 12. In this way, the air in the holding unit 22 is sucked so that the inside of the holding unit 22 becomes negative pressure. maintain When the inside of the unit 22 becomes negative pressure, the air in the pressure fluctuation chamber S1 is also sucked through the atomization container 195 (inside the atomization chamber M) of the cartridge 11 (in the atomization chamber M), the communication space 51, and the pressure fluctuation chamber S1 The inside also becomes negative pressure. Specifically, the air in the pressure fluctuation chamber S1 flows into the buffer space S3 through the communication port 51, and then flows into the heater holder 196 through the second suction hole 216. The air flowing into the heater holder 196 passes through the air passage 226 and the atomizing container 195, and after passing through the flow passage tube 197, passes through the suction nozzle 23 and enters the mouth of the user. The pressure sensor 53 outputs a start signal to the control unit when detecting that the pressure in the pressure fluctuation chamber S1 has not reached a predetermined value, for example.

The control unit that receives the activation signal energizes the heating unit 194 of the casing 11. In addition, the negative pressure in the holding unit 22 causes new air to be introduced into the holding unit 22 through the vent 131. Then, the new air is introduced into the atomization chamber M (storage tank 191) of the cartridge 11 through the first air intake hole 209 formed in the heater holder 196 of the cartridge 11 and the ventilation path 226 of the atomization container 195 The open chamber 203).

When the heating unit 194 is energized, the heating wire 205 generates heat. In this way, the mist gas source impregnated with the liquid of the wick 204 through the porous body 193 is heated and atomized. The atomized mist is filled in the atomizing chamber M. Then, the atomized mist system is sucked to the suction nozzle 23 side through the flow path tube 197 of the storage tank 191 together with the new air introduced into the atomization chamber M. Then, the mixed gas system of the atomized mist and air enters the mouth of the user through the tobacco capsule 12. In this way, the user can taste the flavor of tobacco.

<The role of the box>

In addition, in the cartridge 11, the mist source of the liquid stored in the liquid storage chamber 202 of the storage tank 191 is sucked into the porous body 193 and then sucked into the wick 204. If porous body 193, wick 204 When saturated (more than the liquid holding capacity of both), a mist source of liquid leaks from the outer peripheral portion of the porous body 193 and the inner peripheral surface of the peripheral wall 191b of the storage tank 191 to the heater holder via the inner peripheral surface 196 side of the risk.

Here, the atomization container 195 located on the heater holder 196 side of the porous body 193 is formed with a liquid storage portion 223 on the outer peripheral surface. Therefore, the mist source of liquid is accumulated in the liquid accumulating portion 223 to prevent leakage from the heater holder 196 side.

Specifically, in the present embodiment, the capacity (space volume) of the liquid reservoir 223 is approximately 53.4 mm ³ . Further, assuming that the remaining amount of liquid in the liquid storage chamber 202 of the storage tank 191 is 1/3, the head space volume expansion rate (the volume expansion rate of air in the remaining 2/3 of the space portion in the liquid storage chamber 202) is 6 At %, the air in the liquid storage chamber 202 of the storage tank 191 expands, and a mist source of liquid of about 100 mm ³ is pushed out from the liquid storage chamber 202. Among the mist source of the extruded liquid, the mist source of about 20 to 30 mm ³ can be held by the porous body 193 and the liquid absorbing core 204. Among the mist source of liquid of about 100 mm ³ , the remaining mist source of 70 to 80 mm ³ is accumulated in the liquid accumulation part 223.

Here, the liquid storage portion 223 is formed so that the gap between the outer peripheral surface of the cylindrical portion 217 and the peripheral wall 191b of the reservoir 191 gradually narrows from the sealing portion 222 toward the front end of the protruding portion 219. In other words, in the vicinity of the protruding portion 219 of the cylindrical portion 217, a narrow portion 279 in which the gap between the protruding portion 219 and the peripheral wall 191b of the storage tank 191 becomes narrow is formed. Therefore, among the mist source of the liquid squeezed out from the liquid storage chamber 202 of the storage tank 191, the remaining mist source system after the porous body 193 and the wick 204 are saturated is easily sucked into the narrow portion 279 and actively passes through The narrow portion 279 flows to the liquid storage portion 223.

In other words, the mist source of the liquid stored in the liquid storage chamber 202 of the storage tank 191 is first sucked into the porous body 193 and then sucked into the liquid wick 204. After the porous body 193 and the liquid absorbing core 204 are saturated, the mist source system of the liquid is sucked into the narrow portion 279 and accumulated in the liquid accumulation portion 223.

On the other hand, when the saturated state of the porous body 193 is released, the mist source of the liquid stored in the liquid storage portion 223 is sucked through the narrow portion 279 (between the protruding portion 219 and the peripheral wall 191b of the storage tank 191). Then, the mist source of the liquid is sucked into the porous body 193. In other words, the mist source of the liquid accumulated in the liquid accumulation part 223 flows back to the liquid storage chamber 202 of the storage tank 191 through the narrow part 279. At this time, since the narrow portion 279 is covered (plugged) by the outer peripheral portion of the porous body 193, the capillary force of the porous body 193 also acts, and the mist source of the liquid is efficiently returned to the liquid storage chamber 202 of the storage tank 191.

In addition, since the sealing portion 222 of the cylindrical portion 217 is formed with two notch portions 222a, the liquid accumulating portion 223 and the outside air pass through the notch portion 222a of the sealing portion 222 and the engagement hole 198 of the reservoir 191 and the heater holder 196 Between the engaging pieces 206 (engaging claws 207). In another embodiment, the liquid accumulating portion 223 and the outside air may also communicate with each other through the notch portion 222a of the sealing portion 222 and the first air intake hole 209 of the heater holder 196. Therefore, there is no pressure difference between the inside and the outside of the liquid accumulation portion 223. Therefore, it is possible to prevent the liquid mist gas source from accidentally flowing out of the liquid accumulation portion 223 to the outside, and at the same time, efficiently return the liquid mist gas source to the liquid storage chamber 202 of the storage tank 191.

In this embodiment, the switching element 52 is mounted on the first substrate 60 by surface mounting, and the pressure sensor 53 is mounted on the first substrate 60 in a state of penetrating through the first substrate 60.

According to this configuration, by mounting the switching element 52 and the pressure sensor 53 so as to be offset in the in-plane direction of the first substrate 60, a space for mounting the through hole of the pressure sensor 53 can be secured on the first substrate 60. With this, the cost of the power supply unit 21 can be reduced.

In this embodiment, the casing 11 is configured to be detachable from the power supply unit 21. Therefore, the mist source can be replenished through the assembly and disassembly operations of the cartridge body 11, and the complexity of the filling operation of the mist source can be reduced. As a result, good operability can be achieved.
