  The mesh body 193 is a porous member having liquid absorbency. The mesh body 193 is formed of, for example, a cotton-based fiber material. The mesh body 193 is also formed in substantially the same shape as the gasket 192. That is, the mesh body 193 is formed so that the outer diameter is substantially the same as the inner diameter of the tank 191. At the radial center of the mesh body 193, an insertion hole 193a into which the flow path pipe 197 can be inserted is formed. The flow path pipe 197 is inserted into the insertion hole 193 a, and the one surface 193 b of the mesh body 193 overlaps the other surface 192 d of the gasket 192 to determine the position of the mesh body 193. The outer peripheral surface of the mesh body 193 is in contact with the inner peripheral surface of the tank 191. Further, the insertion hole 193 a of the mesh body 193 is in contact with the outer peripheral surface of the flow path pipe 197.

The mesh body 193 divides the inside of the tank 191 into a liquid storage chamber 202 on the bottom 191 c side and an opening chamber 203 on the opening 191 a side. The liquid storage chamber 202 stores an aerosol source of liquid. The opening chamber 203 is a chamber for atomizing the aerosol source absorbed by the mesh body 193.
The other surface 193 c opposite to the one surface 193 b of the mesh body 193 is exposed to the opening chamber 203. A heating unit 194 is provided so as to be connected to the other surface 193 c of the mesh body 193 exposed to the opening chamber 203.

The heating unit 194 is for atomizing a liquid aerosol source. The heating unit 194 is housed in the opening chamber 203. The heating unit 194 includes a wick 204 formed in a substantially U shape, and a heating wire 205 for heating the wick 204. The wick 204 is a porous, substantially cylindrical member having liquid absorption. Such a wick 204 is curved and deformed into a substantially U shape.
More specifically, the wick 204 includes: two axially extending portions 204a extending in the axial direction; and a radially extending portion 204c connecting one ends of the two axially extending portions 204a via the bending portion 204b. , Is composed of. The other end of the axially extending portion 204 a is connected to the mesh body 193. As a result, the aerosol source absorbed by the mesh body 193 is absorbed by the wick 204.

  The heating wires 205 are directed toward the heater holder 196 along the axial direction from both ends of the heating wire main body 205a spirally formed so as to surround the periphery of the radially extending portion 204c of the wick 204 and the heating wire main body 205a. And two terminal units 205b extending out. When the wick 204 is heated by the heating wire 205, the aerosol source absorbed by the wick 204 is atomized. The tips of the two terminal portions 205 b are folded back toward the mesh body 193. The two terminal units 205 b are connected to the heater holder 196.

FIG. 16 is a perspective view of the heater holder 196 as viewed from the side of the power supply unit 21 (the first side in the axial direction).
As shown in FIGS. 13 and 16, the heater holder 196 is formed in a substantially bottomed cylindrical shape. The opening 191 a of the tank 191 is closed by turning the opening 196 a of the heater holder 196 toward the tank 191.

  The peripheral wall 196 b of the heater holder 196 is formed such that the outer diameter thereof is substantially the same as the outer diameter of the peripheral wall 191 b of the tank 191. On the outer peripheral surface of the peripheral wall 196b, a fitting portion 196d reduced in diameter via the step surface 196c is formed between the substantially central portion in the axial direction and the opening 196a. The fitting portion 196 d is fitted to the inner peripheral surface of the peripheral wall 191 b of the tank 191. Further, an end portion on the opening 191 a side of the peripheral wall 191 b of the tank 191 is in contact with the step surface 196 c of the peripheral wall 196 b. Thereby, axial positioning of the heater holder 196 with respect to the tank 191 is performed.

Further, two engagement pieces 206 are integrally formed at positions corresponding to the two engagement holes 198 of the tank 191 at the end of the fitting portion 196d on the opening 196a side. The two engagement pieces 206 project toward the corresponding engagement holes 198. That is, the two engagement pieces 206 are disposed opposite to each other on both sides of the axis line Q of the heater holder 196.
The engagement piece 206 is engaged with the engagement hole 198 of the tank 191 to integrate the tank 191 and the heater holder 196. The engagement piece 206 is formed to be elastically deformable in the radial direction. At the tip of the engagement piece 206, an engagement claw 207 which can be inserted into the engagement hole 198 of the tank 191 is formed so as to protrude radially outward.

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

  Further, in the peripheral wall 196b of the heater holder 196, a recessed portion 208 aligned with the engaging claw 207 in the axial direction is formed on the outer peripheral surface avoiding the fitting portion 196d. The concave portion 208 is open at the radially outer side and the step surface 196 c side. In the recess 208, a first intake hole 209 which penetrates the peripheral wall 196b in the thickness direction is formed. The inside and the outside of the peripheral wall 196 b are in communication with each other through the first air intake hole 209.

Furthermore, in the peripheral wall 196b of the heater holder 196, three engagement recesses (regulating portions) 210 are formed on the bottom portion 196e side. The three engagement recesses 210 are arranged at equal intervals in the circumferential direction (120 degrees in the circumferential direction) and so as to avoid the formation position of the recesses 208. The engagement recess 210 is formed such that the radially outer side and the bottom 196 e are open. On the bottom portion 196e side of the engagement recess 210, a tapered flat portion (taper portion) 210a is formed, in which the circumferential width of the engagement recess 210 gradually increases toward the bottom portion 196e.
The longitudinal engagement convex portions (convex portions) 101 a to 101 c of the first connection member 81 are inserted into the three engagement concave portions 210 formed in this manner. Accordingly, the heater holder 196 (the cartridge 11) and the first connecting member 81 are connected, and the circumferential positioning of the heater holder 196 (the cartridge 11) and the first connecting member 81 is performed.

A substantially plate-like connecting wall 211 erected along the axial direction from the inner surface is integrally formed on a bottom portion 196 e of the heater holder 196. The connection wall 211 extends in the radial direction passing through the axis Q of the heater holder 196, and both longitudinal ends in the radial direction are connected to the inner surface of the peripheral wall 196b. The inside of the heater holder 196 is divided into two rooms by such a connecting wall 211.
Furthermore, two slits 212 are formed in the bottom portion 196 e of the heater holder 196. The two slits 212 are disposed along the both sides in the plate thickness direction of the connection wall 211.

  Electrodes 213 and 214 are provided on both surfaces in the thickness direction of the connection wall 211, respectively. The electrodes 213 and 214 are connected to the lead electrode portions 213a and 214a provided on the connection wall 211 and the connection electrode portion bent and extended from the lead electrode portions 213a and 214a to the outer surface of the bottom portion 196e via the corresponding slits 212 ( A first planar electrode and a second planar electrode) 213b and 214b. The two terminal portions 205b of the heating wire 205 constituting the heating unit 194 are separately connected to the lead-out electrode units 213a and 214a.

  The connection electrode portions 213 b and 214 b are formed substantially in a semicircular shape on both sides in the radial direction with an insulating portion 215 described later interposed therebetween. Specifically, the two connection electrode portions 213b and 214b are arranged in a shape in which straight sides 213c and 214c in the axial direction are opposed in the radial direction. Further, in the two connection electrode portions 213b and 214b, arc side arcs 213d and 214d having a circular arc shape viewed from the axial direction form an outer peripheral portion. An end of the connection wall 211 is interposed between the sides 213c and 214c of the two connection electrode portions 213b and 214b. In the state where the heater holder 196 (the cartridge 11) and the first connection member 81 are connected to each of the connection electrode portions 213b and 214b, the tip of the pin electrode 49 (electrode body) held by each electrode holding portion 50 contacts Be done. That is, the bottom portion 196e of the heater holder 196 functions as an electrode disposition surface (second electrode disposition surface) axially opposed to the above-described base surface 91a in the mounting state of the cartridge 11 to the main body unit 10.

  Here, each connection electrode portion 213b, 214b rotates the pin electrode 49 (first pin electrode 49a and second pin electrode 49b) when the power supply unit 21 and the cartridge 11 rotate relative to each other about the axis O (axis Q). It is formed at least on the trajectory. That is, each connection electrode portion 213b, 214b has a first imaginary circumference C1 passing through the first pin electrode 49a about the axis O and a second imaginary circumference C2 passing through the second pin electrode 49b about the axis O. It is formed in the area | region containing both. In the present embodiment, since the pin electrodes 49a and 49b are disposed in line symmetry, the imaginary circumferences C1 and C2 coincide with each other.

  In addition, since the end of the connection wall 211 interposed between the sides 213c and 214c of the two connection electrode portions 213b and 214b extends in the radial direction passing through the axis Q of the heater holder 196, in other words, For example, it can be said that the connection wall 211 is provided on the virtual straight line T1 in a predetermined direction among the virtual straight lines T1 connecting the two pin electrodes 49. The predetermined direction coincides with an imaginary straight line T2 passing through the circumferential center of one of the three engaging recesses 210 formed in the heater holder 196 and the axis Q of the heater holder 196. . The connection wall 211 is formed such that the width in the short direction (the circumferential direction around the axis Q) is slightly larger than the axial diameter of each pin electrode 49.

  The end portion of the connection wall 211 thus arranged functions as an insulating portion 215 that divides the connection electrode portions 213 b and 214 b in the circumferential direction. The heater holder 196 (the cartridge 11) and the first connecting member 81 are connected by arranging the insulating portion 215 on an imaginary straight line T2 passing through the circumferential center of one engaging recess 210 and the axis Q of the heater holder 196. In the set state, the tip of each pin electrode 49 reliably contacts the two connection electrode parts 213b and 214b separately. That is, the two pin electrodes 49 do not simultaneously contact with one of the two connection electrode parts 213b and 214b. As described above, the connection electrode portions 213b and 214b of the present embodiment include virtual circles C1 and C2 on both sides in the radial direction across the virtual straight line T2 (insulation portion 215), and the virtual circle C1. , And C2 are formed in a semicircular shape spreading radially outward (arc side 213d, 214d) and inside (sides 213c, 214c).

  Further, concave portions 213e and 214e that are recessed inward in the radial direction are formed at substantially the center in the circumferential direction on the arc sides 213d and 214d of the two connection electrode portions 213b and 214b. In the bottom portion 196e of the heater holder 196, of the portions corresponding to the concave portions 213e and 214e of the connection electrode portions 213b and 214b, the second suction holes 216 penetrating in the thickness direction of the bottom portion 196e at the portions corresponding to one concave portion 213e. Is formed. The inside and the outside of the bottom portion 196 e are in communication with each other through the second air intake holes 216.

  Further, in the bottom portion 196e, concave portions 196f having the same shape as the connection electrode portions 213b and 214b as viewed from the axial direction are formed at locations corresponding to the connection electrode portions 213b and 214b. The connection electrode portions 213b and 214b are accommodated in the recess 196f. By forming the concave portion 196f, the surfaces of the connection electrode portions 213b and 214b and the surface of the bottom portion 196e where the connection electrode portions 213b and 214b are not disposed are positioned on the same plane. A part of the atomization container 195 is accommodated so as to be fitted to the inner peripheral surface of the peripheral wall 196 b in the heater holder 196.

  As shown in FIG. 11, in the state where the cartridge 11 is mounted in the holding unit 22, the outer peripheral portion of the bottom portion 196e axially abuts on the above-mentioned surrounding convex portion 93. Thus, a space surrounded by the bottom portion 196e and the connection cap 80 (the base surface 91a and the surrounding convex portion 93) forms a buffer space S3 for communicating the inside of the communication port 51 with the second intake hole 216. In the example of FIG. 11, the communication port 51 and the second air intake hole 216 are axially separated from each other, and are disposed at positions mutually offset in the circumferential direction. The communication port 51 and the second intake holes 216 may be arranged at positions mutually offset in the radial direction.

  The communication port 51 of the present embodiment communicates with the inside of the flow path pipe 197 through the buffer space S3, the second intake hole 216, and the like. In the bottom portion (second surface) 196e, the portion in contact with the surrounding convex portion 93 is formed to be a flat surface orthogonal to the axial direction. Of the bottom portion 196e, the portion with which the surrounding convex portion 93 abuts may be a convex surface, a concave surface, an inclined surface or the like.

  In the present embodiment, the surrounding convex portion 93 is in close contact with the bottom portion 196 e in a state of being elastically deformed by the cartridge 11 being pressed by the mouthpiece 23. However, the surrounding convex portion 93 and the bottom portion 196 e do not necessarily have to be in close proximity, and may be separated. That is, as long as negative pressure can be generated in the pressure fluctuation chamber S1 through the communication port 51 at the time of suction, a minute gap may be generated between the surrounding convex portion 93 and the bottom portion 196e.

FIG. 17 is a perspective view of the atomization container 195 as seen from the mesh body 193 side (the second side in the axial direction).
The atomization container 195 shown in FIG. 13, FIG. 14, FIG. 17, etc. is formed of a member having elasticity, for example, a resin material such as silicone resin. The atomization container 195 is provided between the other surface 193 c of the mesh body 193 and the vicinity of the bottom portion 196 e of the heater holder 196 in the axial direction. That is, the atomization container 195 is formed in a substantially cylindrical shape so as to surround the periphery of the heating portion 194, and the cylindrical portion 217 fitted to the inner peripheral surface of the peripheral wall 191b in the tank 191 and the peripheral wall 196b in the heater holder 196 A substantially block-shaped fitting portion 218 fitted to the circumferential surface is integrally formed.

  A step surface 217 a is formed at a large part in the center in the radial direction at an end of the cylindrical portion 217 on the mesh body 193 side. By forming the stepped surface 217a, a ring-shaped protruding portion 219 is formed in which the outer peripheral portion of the cylindrical portion 217 protrudes toward the mesh body 193 side. The end of the protrusion 219 abuts on the other surface 193 c of the mesh 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 191 b of the tank 191.

A storage recess 220 is formed on most of the step surface 217 a so as to correspond to the shape of the heating portion 194. The storage recess 220 serves as an atomization chamber M in which the aerosol atomized by the heating unit 194 is stored. The atomization chamber M is in communication with the flow path pipe 197 of the tank 191.
In the housing recess 220, a seat surface 221 on which the bent portion 204b of the wick 204 constituting the heating unit 194 is placed is formed. A recess 221 a for avoiding interference with the terminal portion 205 b of the heating wire 205 constituting the heating unit 194 is formed on the radial inner surface of the seat surface 221.

A seal portion 222 is formed on the outer peripheral surface of the cylindrical portion 217 near the fitting portion 218. The seal portion 222 is formed so as to protrude radially outward over the entire circumference except for a notch portion 222a described later. The seal portion 222 has a role of ensuring a sealing property between the cylindrical portion 217 and the peripheral wall 191 b of the tank 191, and also has a role of suppressing removal of the atomization container 195 from the tank 191.
The outer diameter of the seal portion 222 is slightly larger than the inner diameter of the peripheral wall 191 b of the tank 191. For this reason, in the state where the atomization container 195 is housed in the tank 191, the seal portion 222 is compressed in the radial direction. As a result, the sealability of the seal portion 222 is secured, and the frictional resistance of the seal portion 222 suppresses the detachment of the atomization container 195 from the tank 191.

  Further, in the seal portion 222, two notches 222a are formed. The two notches 222 a are disposed opposite to each other on both sides of the axis line Q of the tank 191. Outside air and the below-mentioned liquid reservoir part 223 are connected by notch part 222a.

  A liquid reservoir portion 223 is formed on the outer peripheral surface of the cylindrical portion 217 from the tip of the projecting portion 219 to the seal portion 222. In the liquid reservoir portion 223, when the mesh body 193 and the wick 204 are saturated, the aerosol source of the liquid stored in the liquid storage chamber 202 of the tank 191 leaks along the inner peripheral surface of the peripheral wall 191b of the tank 191 In this case, it is a site for temporarily storing the leaked aerosol source.

In the liquid reservoir portion 223, the gap between the outer peripheral surface of the cylindrical portion 217 and the peripheral wall 191b of the tank 191 gradually narrows as the entire outer peripheral surface of the cylindrical portion 217 moves from the seal portion 222 toward the tip of the projecting portion 219. It is a recess formed by forming obliquely. In other words, the liquid reservoir portion 223 is a recessed portion in which the gap between the outer peripheral surface of the cylindrical portion 217 and the peripheral wall 191b of the tank 191 gradually becomes wider as it goes to the opening 191a of the tank 191. Thus, since the liquid reservoir portion 223 is formed, in the vicinity of the projecting portion 219 of the cylindrical portion 217, a narrow portion 279 in which a small gap is formed between the projecting portion 219 and the peripheral wall 191b of the tank 191 is formed.
Here, the end of the projecting portion 219 in the cylindrical portion 217 is in contact with the other surface 193 c of the mesh body 193. The outer peripheral surface of the mesh body 193 is in contact with the inner peripheral surface of the tank 191. For this reason, the narrow portion 279 formed between the protrusion 219 of the cylindrical portion 217 and the peripheral wall 191 b of the tank 191 is covered with the outer peripheral portion of the mesh body 193 (closed).

  Further, on the outer peripheral surface of the cylindrical portion 217, a concave portion 224 for receiving the engagement piece 206 is formed at a position corresponding to the engagement piece 206 closer to the heater holder 196 than the seal portion 222. Positioning of the atomization container 195 and the heater holder 196 in the circumferential direction is performed by inserting the engagement piece 206 into the recess 224. Further, the bottom surface 224 a of the concave portion 224 in the cylindrical portion 217 is in contact with the inner surface in the radial direction of the engagement piece 206.

  The fitting portion 218 of the atomization container 195 is formed in a substantially cylindrical shape that can be fitted to the inner peripheral surface of the peripheral wall 196 b of the heater holder 196. That is, the fitting portion 218 is formed such that the outer diameter thereof is smaller than the outer diameter of the cylindrical portion 217 via the step portion 217 b. The fitting portion 218 is formed with a slit 225 into which the connection wall 211 of the heater holder 196 can be inserted. Further, the fitting portion 218 is formed with a heating wire slit (not shown) which communicates with the slit 225 and into which the end portion 205b of the heating wire 205 can be inserted. The terminal portion 205b of the heating wire 205 is inserted into the slit for the heating wire, whereby the terminal portion 205b is held by the atomization container 195. Further, the lead-out electrode portions 213 a and 214 a provided on the connection wall 211 and the terminal portion 205 b of the heating wire 205 are connected.

  Further, in the fitting portion 218, an air passage 226 is formed at a position corresponding to the first intake hole 209 and the second intake hole 216 of the heater holder 196. Furthermore, the fitting portion 218 is formed with a slit 218 a that communicates the slit 225 and the air passage 226 with the atomization chamber M (the housing recess 220) of the cylindrical portion 217. The air passage 226 and the atomization chamber M (the housing recess 220) of the atomization container 195 are communicated with each other through the slit 218a. As a result, the atomization chamber M (the storage recess 220) of the atomization container 195 and the first intake hole 209 and the second intake hole 216 of the heater holder 196 are communicated with each other through the air passage 226 and the slit 218a.

<Assembly structure of entire aspirator>
FIG. 18 is a front view of the suction device 1.
As shown in FIG. 18, the main body unit 10 of the aspirator 1 includes a connecting portion 300 that connects the power supply unit 21, the holding unit 22, and the mouthpiece 23 in the axial direction in which the axis O (central axis) extends. . The connection unit 300 includes a first rotation connection unit 301 connecting the power supply unit 21 and the holding unit 22 and a second rotation connection unit 302 connecting the holding unit 22 and the mouthpiece 23.

  In the following description, among the circumferential directions around the axis O, in a plan view in which the power supply unit 21 side is viewed from the mouthpiece 23 side along the axis O, the direction of circling the axis O clockwise is the rotation direction M1. The direction in which the axis O orbits counterclockwise is referred to as a rotational direction M2.

  The first rotation connection unit 301 performs connection and disconnection between the power supply unit 21 and the holding unit 22 by relative rotation around the axis O of the power supply unit 21 and the holding unit 22. When the holding unit 22 is rotated in the rotational direction M1 with respect to the power supply unit 21 based on the power supply unit 21, the power supply unit 21 and the holding unit 22 are connected. Further, when the holding unit 22 is rotated in the rotational direction M2 with respect to the power supply unit 21, the connection between the power supply unit 21 and the holding unit 22 is released.

  The first rotary connection portion 301 includes the rotary connection mechanism 310 by the first connection member 81 and the second connection member 122 shown in FIG. 9 described above, and the annular piece 82 and the second connection member 122 shown in FIG. 9 and FIG. The lock mechanism 311 is provided. Specifically, as shown in FIG. 9, the rotational connection mechanism 310 is provided with the lateral engagement convex portion 102 provided on the first connection member 81 of the power supply unit 21 on the second connection member 122 of the holding unit 22. After the holder unit 22 is rotated in the rotational direction M1 (see FIG. 18) with respect to the power supply unit 21 after being inserted in the engaging groove 158 in the axial direction, the lateral engagement convex portion 102 is engaged with the engagement piece 142. Power supply unit 21 and holding unit 22 are connected.

  The lock mechanism 311 regulates the rotation of the holding unit 22 in the rotational direction M2 in which the connection by the rotational connection mechanism 310 is released. Specifically, as shown in FIGS. 9 and 10, the lock mechanism 311 is provided on the annular piece 82 attached to the power supply unit 21 and includes a bending portion 106 protruding outward in the radial direction, and a holding unit 22. And a tip portion 142a which is provided on the second connection member 122 and which protrudes inward in the radial direction relative to the bottom portion of the engagement recess 155 in the locking piece 142. The tip end portion 142 a of the locking piece 142 is located on the movement path of the bending portion 106 around the axis O.

  At the time of connection in the rotary connection mechanism 310 (when the holding unit 22 is rotated in the rotational direction M1 with respect to the power supply unit 21), the bending portion 106 and the tip portion 142a of the locking piece 142 contact and the bending portion 106 The tip end portion 142a is climbed while being elastically deformed inward in the radial direction. After passing over the tip end portion 142 a, the bending portion 106 restores and deforms outward in the radial direction, and engages with the engagement recess 155. When the bending portion 106 engages with the engagement recess 155, the bending portion 106 faces and locks the tip portion 142a of the locking piece 142 in the rotational direction M1. As a result, the connection between the power supply unit 21 and the holding unit 22 can not be released unless a certain amount of force is applied.

  According to the first rotation connection portion 301, even in the case where the power supply unit 21 and the holding unit 22 can be divided as in the present embodiment for improvement of manufacturing efficiency etc., the power supply unit by the rotation connection mechanism 310 The connection between the power supply unit 21 and the holding unit 22 can be facilitated by the locking mechanism 311, and the reliability (connection strength) of the connection between the power supply unit 21 and the holding unit 22 can be improved. In addition, since the locking by the lock mechanism 311 is performed simultaneously with the connection by the rotational connection mechanism 310, the convenience of the assembly (usability) can be improved.

  In the lock mechanism 311, as shown in FIG. 10, the elastically deforming flexible portion 106 is disposed radially inward of the locking piece 142 whose thickness is higher than that of the annular piece 82. Therefore, in the state where the power supply unit 21 and the holding unit 22 are connected, the bending portion 106 is covered from outside by the locking piece 142 and protected. Therefore, even if there is a drop, a collision or the like, the number of cases in which the bending portion 106 is damaged is reduced. This ensures strength against repeated assembly use and improves the reliability of the lock.

  As shown in FIG. 9, the locking piece 142 locked by the bending portion 106 forms an engagement groove 158 with which the lateral engagement convex portion 102 of the rotational connection mechanism 310 engages. Thus, the locking piece 142 forms a part (engaging groove 158) of the rotary connection mechanism 310 and a part (tip end 142a (convex part)) of the locking mechanism 311, The reliability of the connection state (connection strength) can be relatively easily improved.

  As shown in FIG. 18, the second rotational connection portion 302 performs connection and disconnection between the holding unit 22 and the mouthpiece 23 by relative rotation around the axis O of the holding unit 22 and the mouthpiece 23. When the holding unit 22 is used as a reference, when the mouthpiece 23 is rotated in the rotational direction M1 with respect to the holding unit 22, the holding unit 22 and the mouthpiece 23 are connected. Further, when the mouthpiece 23 is rotated in the rotational direction M2 with respect to the holding unit 22, the connection between the holding unit 22 and the mouthpiece 23 is released.

  As shown in FIG. 11 described above, the second rotary connection portion 302 includes an external thread portion 160 a provided on the mouthpiece 23 and an internal thread portion 123 a provided on the holding unit 22. Specifically, the second rotational connection portion 302 rotates the male screw portion 160a provided on the mouthpiece 23 in the rotational direction M1 with respect to the female screw portion 123a provided on the holding unit 22 to thereby hold the holding unit 22 and the male screw portion 160a. Connect the mouthpiece 23. Further, the male screw portion 160a provided on the mouthpiece 23 is rotated in the rotational direction M2 with respect to the female screw portion 123a provided on the holding unit 22, thereby releasing the connection between the holding unit 22 and the mouthpiece 23.

  As shown in FIG. 18, the rotational direction M1 is the connection direction of the holding unit 22 to the power supply unit 21 and is also the connection direction of the mouthpiece 23 to the holding unit 22. Further, the rotational direction M2 is a connection release direction of the holding unit 22 with respect to the power supply unit 21 and is also a connection release direction of the mouthpiece 23 with respect to the holding unit 22. Thus, in the first rotational connection portion 301 and the second rotational connection portion 302, the rotational directions of the connection and disconnection around the axis O coincide with each other. For this reason, it is possible to give the user a sense of unity in unit assembly work and to improve the convenience (usability).

  The frequency of releasing the connection between the mouthpiece 23 and the holding unit 22 for replacement of the cartridge 11 or the like is higher than the frequency of releasing the connection between the power supply unit 21 and the holding unit 22. In this embodiment, in the first rotational connection portion 301, the connection between the power supply unit 21 and the holding unit 22 is released by applying a first torque 301T around the axis O, and in the second rotational connection portion 302, The connection between the holding unit 22 and the mouthpiece 23 is released by applying a second torque 302T smaller than the first torque 301T. Accordingly, it is possible to prevent the co-rotation of the holding unit 22 and the power supply unit 21 when the mouthpiece 23 is removed from the holding unit 22.

  The first torque 301T is a peak value of a torque value when the holding unit 22 rotates in the rotational direction M2 with respect to the power supply unit 21, and for the elastic deformation in the radial direction of the bending portion 106 shown in FIGS. It depends on the spring coefficient etc. The second torque 302T is a peak value of a torque value when the mouthpiece 23 rotates in the rotational direction M2 with respect to the holding unit 22, and the static friction force between the male screw 160a and the female screw 123a shown in FIG. Depends on The first torque 301T may be, for example, 1.5 times or more than the second torque 302T.

  Since the first rotational connection portion 301 and the second rotational 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 sorting or adjusting the thickness of the material of the flexible portion 106 (annular piece 82) forming the lock mechanism 311 of the first rotational connection portion 301, the spring coefficient for the elastic deformation in the radial direction of the flexible portion 106 is changed, The magnitude of the first torque 301T with respect to the second torque 302T can be easily adjusted.

FIG. 19 is a cross-sectional view along the axial direction when the mouthpiece 23 is removed from the aspirator 1.
As shown in FIG. 19, in the suction unit 1, the cartridge 11 can be attached and detached in the axial direction by removing the mouthpiece 23 from the main body unit 10. In addition, what removed the mouthpiece 23 from the main body unit 10 is called the cartridge accommodating part 320. That is, the cartridge housing portion 320 includes the holding unit 22 and the power supply unit 21.

  The cartridge housing portion 320 forms a bottomed cylindrical cartridge housing space 321. The peripheral wall of the cartridge housing portion 320 forming the cartridge housing space 321 is formed by the holding unit 22. Further, the bottom of the cartridge accommodating portion 320 forming the cartridge accommodating space 321 is formed by the power supply unit 21. That is, the peripheral wall (holding unit 22) of the cartridge housing portion 320 is attachable to and detachable from the bottom portion (power supply unit 21) of the cartridge housing portion 320.

  At the bottom of the cartridge housing portion 320, the longitudinal engagement convex portion 101 (the longitudinal engagement convex portions 101a to 101c are denoted by the reference numeral 101 in FIG. 19 and later) provided on the above-described first connection member 81 is an axis. Standing in the direction. The longitudinal engagement convex portion 101 is arranged to be insertable in the axial direction with respect to the engagement concave portion 210 provided in the cartridge 11. That is, the vertical engagement convex portion 101 and the engagement concave portion 210 are disposed on the same radius centering on the axis O. The vertical engagement convex portion 101 and the engagement concave portion 210 form a first rotation restricting portion 330 which restricts relative rotation around the axis O with respect to the cartridge accommodating portion 320 (cartridge accommodating space 321) of the cartridge 11.

  In the first rotation restricting portion 330, when the cartridge 11 and the cartridge accommodating portion 320 are relatively rotated about the axis O, the vertical engagement convex portion 101 provided on the same radius is inserted into the engagement concave portion 210, and the cartridge Rotational regulation about the axis O of 11 is performed. Thereby, the cartridge 11 is positioned in the circumferential direction, and electrical continuity between the connection electrode portions 213 b and 214 b (see FIG. 10) of the bottom portion 196 e of the cartridge 11 and the pin electrode 49 of the power supply unit 21 is secured.

  The first rotation restricting portion 330, together with the mouthpiece 23, interlocks with the screw attachment of the mouthpiece 23 to the cartridge accommodating portion 320 (holding unit 22) to position the cartridge 11 relative to the cartridge accommodating portion 320. It is formed. According to this positioning mechanism 340, the positioning of the cartridge 11 can be performed simultaneously with the screwing of the mouthpiece 23 to the cartridge housing portion 320. Therefore, positioning of the removable cartridge 11 with respect to the cartridge housing portion 320 is facilitated, and assembly complexity is eliminated. In addition, it is not necessary to directly rotate the cartridge 11 by hand.

  Specifically, the mouthpiece 23 includes the above-described first anti-slip member (cartridge contact portion) 161 that rotates the cartridge 11 about the axis O with respect to the cartridge storage portion 320. The first anti-slip member 161 is attached to the mouthpiece body 160 and abuts on the cartridge 11 while the mouthpiece body 160 is connected to the holding unit 22. When the first anti-slip member 161 abuts on the cartridge 11, the cartridge 11 starts to rotate with the mouthpiece 23, and the circumferential position of the engagement recess 210 and the longitudinal engagement protrusion 101 coincide with each other. The cartridge 11 is positioned in the circumferential direction by the fall of the force of gravity toward the bottom side of the cartridge housing portion 320 and the longitudinal engagement convex portion 101 being inserted into the engagement concave portion 210.

  Furthermore, when the mouthpiece 23 is screwed in, the first anti-slip member 161 is axially compressed between the cartridge 11 supported by the power supply unit 21 (longitudinal engagement convex portion 101 etc.) and the mouthpiece main body 160. Be done. The first anti-slip member 161 presses the cartridge 11 toward the power supply unit 21 in a state in which the mouthpiece 23 is screwed to the holding unit 22 as shown in FIG. Thereby, the axial positioning of the cartridge 11 is performed.

  Since the first antislip member 161 is formed of silicone resin as described above, it exerts a frictional force that causes the cartridge 11 to rotate in the circumferential direction, and exerts a pressing force that presses the cartridge 11 in the axial direction. Cheap. Further, as shown in FIG. 19, the first anti-slip member 161 has an abutment protrusion 171 formed on the opposing surface 161 a facing the cartridge 11. Since the contact projections 171 prevent the first anti-slip member 161 from coming into contact with the cartridge 11 in a plane contact, the contact pressure is increased, and the frictional force in the circumferential direction and the pressing force in the axial direction are more easily expressed.

  Further, as shown in FIG. 11, the contact projection 171 is axially squeezed so that the space between the through hole 191 d of the cartridge 11 and the communication hole 169 a of the first anti-slip member 161 is airtightly sealed. The flow paths of the cartridge 11 and the mouthpiece 23 communicate with each other, and the aerosol generated by the cartridge 11 can be sucked through the mouthpiece 23. The abutment projection 171 is formed in a double annular shape (see FIG. 12), so that a highly airtight double seal can be formed.

  The mouthpiece 23 includes a second rotation restricting portion 350 which restricts the relative rotation of the first anti-slip member 161 with respect to the mouthpiece body 160, as shown in FIG. The second rotation restricting portion 350 includes a fitting projection 170 (see FIG. 12) provided on the first anti-slip member 161 and a through hole 168 (see FIG. 12) of an elongated hole provided on the mouthpiece main body 160. It is formed by The fitting projections 170 extend in a pair in the axial direction toward the mouthpiece body 160 and are fitted to both longitudinal ends of the through hole 168.

  According to the second rotation restricting portion 350, even if the condensed aerosol is accumulated between the mouthpiece main body 160 and the first anti-slip member 161, the idle rotation of the first anti-slip member 161 with respect to the mouthpiece main body 160 ( Can prevent sliding. Therefore, positioning in the circumferential direction of the cartridge 11 can be performed reliably. Further, the through hole 168 may be formed in a long hole and integrated with the suction port 23a.

[Effect]
<Assembly method of aspirator>
Next, the assembling method of the suction device 1 mentioned above is demonstrated.
As shown in FIG. 2, when assembling the suction device 1 of the present embodiment, first, the holding unit 22 is assembled to the power supply unit 21. Specifically, after the lateral engagement convex portion 102 is axially inserted into the engagement groove 158, the power supply unit 21 and the holding unit 22 are relatively rotated around the axis O. Then, the power supply unit 21 and the holding unit 22 are assembled to each other in the state where the positioning in the axial direction and the circumferential direction is performed in the first rotational connection portion 301 described above. When the power supply unit 21 and the holding unit 22 are removed, an operation reverse to the operation described above is performed.

  Subsequently, the cartridge 11 is inserted into the holding unit 22. Specifically, the cartridge 11 is inserted into the holding unit 22 in a state where the connection electrode portions 213 b and 214 b of the cartridge 11 are directed to the holding unit 22 in the axial direction. When the circumferential direction positions of the longitudinal engagement convex portions 101a to 101c of the power supply unit 21 and the engagement concave portion 210 of the cartridge 11 coincide with each other, the engagement concave portion 210 corresponding to each longitudinal engagement convex portion 101a to 101c. It is inserted inside. The flat recess 210a is formed in the engagement recess 210, and an inclined surface is formed at the tip of the vertical engagement projections 101a to 101c. Therefore, the longitudinal engagement projections 101a to 101c are smoothly inserted into the engagement recess 210. Thereby, the circumferential direction and the axial direction of the cartridge 11 with respect to the power supply unit 21 are positioned, and the cartridge 11 is assembled to the power supply unit 21 at a proper position.

  That is, one pin electrode 49 of the pin electrodes 49 of the power supply unit 21 and one of the connection electrode parts 213 b and 214 b of the connection electrode parts 213 b and 214 b of the cartridge 11 are connected. Further, the other pin electrode 49 is connected to the other connection electrode portion 213 b, 214 b of the connection electrode portions 213 b, 214 b in the cartridge 11. The electric 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 213 b and 214 b (electrodes 213 and 214). Furthermore, when the bottom portion 196e of the cartridge 11 abuts on the surrounding convex portion 93, a buffer space S3 is defined by the cartridge 11 and the connection cap 80.

  Next, the mouthpiece 23 is assembled to the holding unit 22 by the above-described second rotational connection portion 302. Specifically, the male screw portion 160 a of the mouthpiece main body 160 is screwed to the female screw portion 123 a of the sleeve 123. Then, the first anti-slip member 161 of the mouthpiece 23 contacts the bottom 191 c of the cartridge 11. In this state, when the mouthpiece 23 is further tightened, the first anti-slip member 161 is elastically deformed so that the cartridge 11 is held in the holding unit 22 in a state of being pressed toward the power supply unit 21 side in the axial direction. Be done. In addition, the movement of the cartridge 11 in the circumferential direction with respect to the power supply unit 21 is restricted by the longitudinal engagement convex portions 101a to 101c. Therefore, the cartridge 11 does not rotate with the mouthpiece 23 depending on the frictional force acting between the first anti-slip member 161 and the cartridge 11.

Next, the tobacco capsule 12 is inserted into the mouthpiece 23. Specifically, with the mesh opening directed to the mouthpiece 23, the tobacco capsule 12 is fitted in the mouthpiece main body 160.
Thus, the assembly of the suction device 1 is completed.

  By the way, at the time of insertion of the cartridge 11 described above, depending on the circumferential direction of the cartridge 11, the circumferential positions of the vertical engagement convex portions 101a to 101c of the power supply unit 21 and the engagement concave portion 210 of the cartridge 11 are It may not match. In this case, the bottom portion 196e of the cartridge 11 is in a state in which it rides on the vertical engagement convex portions 101a to 101c (hereinafter, simply referred to as a "on state").

FIG. 20 is an explanatory view showing a state where the cartridge 11 rides on the vertical engagement convex portion 101. As shown in FIG.
As shown in FIG. 20, in the state in which the cartridge 11 is mounted, movement of the cartridge 11 relative to the power supply unit 21 in the axial direction toward the power supply unit 21 is restricted. Therefore, the pin electrode 49 and the connection electrode portions 213 b and 214 b are separated in the axial direction, and the conduction between the power supply unit 21 and the cartridge 11 is not ensured. Even if the pin electrode 49 and the connection electrode parts 213b and 214b contact in the riding state, the pin electrode 49 and the connection electrode parts 213b and 214b may not be disposed at desired circumferential positions.

FIG. 21 is an explanatory view showing a state in which the mouthpiece 23 is screwed in a state where the cartridge 11 is lifted.
As shown in FIG. 21, when the mouthpiece 23 is rotated while the cartridge 11 is in the mounted state, and screwed to the holding unit 22, as shown in FIG. 22 described later, at least the first slip is completed before screwing is completed. The member 161 abuts on the cartridge 11. Specifically, as shown in FIG. 21, the moment when the male screw 160a of the mouthpiece 23 is applied to the female screw 123a of the holding unit 22, the first anti-slip member 161 is not in contact with the cartridge 11, as shown in FIG. As shown in FIG. 6, when the male screw portion 160a is screwed into the female screw portion 123a and the half rotation is performed for one or two turns, the first anti-slip member 161 abuts on the cartridge 11.

FIG. 22 is an explanatory view showing how the mouthpiece 23 and the cartridge 11 rotate together.
As shown in FIG. 22, when the screwing operation of the mouthpiece 23 is continued with the first anti-slip member 161 in contact with the cartridge 11, the friction acting between the first anti-slip member 161 and the cartridge 11 The force causes the mouthpiece 23 and the cartridge 11 to rotate together. That is, the screwing operation of the mouthpiece 23 rotates the cartridge 11 in the circumferential direction (tightening direction (rotational direction M1)) while being pressed against the power supply unit 21 side in the axial direction.

  Thereafter, when the circumferential positions of the connection electrode portions 213b and 214b of the cartridge 11 and the longitudinal engagement convex portions 101a to 101c of the power supply unit 21 match, the engagement concave portion 210 corresponding to the longitudinal engagement convex portions 101a to 101c. Enter inside. That is, the axial movement of the cartridge 11 with respect to the power supply unit 21 is permitted, whereby the cartridge 11 is assembled at the correct position. Thus, the pin electrode 49 and the connection electrode portions 213b and 214b come into contact with each other in a state in which movement of the cartridge 11 in the circumferential direction with respect to the power supply unit 21 is restricted.

FIG. 23 is an explanatory view showing a state in which the mouthpiece 23 is tightened to the end.
As shown in FIG. 23, by the positioning of the longitudinal engagement convex portion 101 and the engagement concave portion 210 in the circumferential direction, if the axial movement of the cartridge 11 is permitted, further screwing of the mouthpiece 23 becomes possible. When the mouthpiece 23 is tightened to the end, the connection electrode portions 213b and 214b are pressed against the pin electrode 49, and the first anti-slip member 161 is between the cartridge 11 supported by the power supply unit 21 and the mouthpiece body 160. Axially compressed, the cartridge 11 is positioned in the axial direction. As described above, by screwing the mouthpiece 23, positioning of the cartridge 11 in the circumferential direction and the axial direction, and electrical conduction between the cartridge 11 and the power supply unit 21 are performed. In addition, the contact projection 171 of the first anti-slip member 161 is axially compressed, whereby the gap between the cartridge 11 and the mouthpiece 23 is sealed.
Further, as described above, when the cartridge 11 is assembled at the proper position, the surrounding convex portion 93 of the connection cap 80 abuts on the cartridge 11. Therefore, a buffer space S3 (see FIG. 3) surrounded by the surrounding convex portion 93 is formed between the bottom portion 196e of the heater holder 196 of the cartridge 11 and the connection cap 80.

<Assembling method of cartridge>
Next, a method of assembling the cartridge 11 described above will be described.
First, the liquid storage chamber 202 of the tank 191 is filled with an aerosol source of liquid, and then the gasket 192 and the mesh body 193 are inserted in this order from the opening 191 a of the tank 191. At this time, one surface 192 b of the gasket 192 is brought into contact with the end surface 201 a of the convex portion 201 of the tank 191. Further, one surface 193 b of the mesh body 193 is superimposed on the other surface 192 d of the gasket 192. As a result, the inside of the tank 191 is correctly divided into the liquid storage chamber 202 and the opening chamber 203 by the mesh body 193. Although the mesh body 193 itself is soft, the posture is held by the gasket 192 and positioning is performed.

  Further, in parallel with the above process, the heating unit 194 and the atomization container 195 are assembled to the heater holder 196. Specifically, first, the heating unit 194 is assembled to the storage recess 220 of the atomization container 195. Subsequently, the fitting portion 218 side of the atomization container 195 is directed to the opening 196 a of the heater holder 196, and the atomization 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 196 b of the heater holder 196. At this time, the connection wall 211 of the heater holder 196 and the slit 225 of the fitting portion 218 are aligned, and the connection wall 211 is inserted into the slit 225.

Subsequently, the heater holder 196 is attached to the opening 191 a of the tank 191. Specifically, the heater holder 196 is inserted into the opening 191 a of the tank 191 so that the engagement piece 206 of the heater holder 196 faces the opening 191 a of the tank 191. At this time, the positions of the engagement hole 198 and the guide recess 198 a formed in the peripheral wall 191 b of the tank 191 and the engagement piece 206 of the heater holder 196 are also matched.
In this state, when the heater holder 196 is inserted into the opening 191a of the tank 191, first, the inclined surface 207a formed on the engaging claw 207 of the engaging piece 206 is brought into contact with the peripheral wall 191b of the tank 191. . The engaging claws 207 smoothly abut on the guide recess 198 a of the tank 191 by the inclined surface 207 a.

  Thereafter, when the heater holder 196 is further pushed into the tank 191, the engagement claws 207 are fitted in the guide concave portions 198a. Then, the engagement piece 206 is pressed radially inward by the guide recess 198a and is elastically deformed. At this time, the engagement piece 206 is elastically deformed radially inward smoothly by the inclined surface 207 a of the engagement claw 207. Here, since the two engagement pieces 206 are disposed opposite to each other on both sides of the axis Q, the radial inward force applied to the two engagement pieces 206 is unlikely to be uneven when viewed from the entire heater holder 196. For this reason, the force at the time of elastically deforming the engagement piece 206 is balanced, and the heater holder 196 can be easily inserted into the opening 191 a of the tank 191. Further, the bottom surface 224 a of the recess 224 of the atomization container 195 is in contact with the inner surface on the inner side in the radial direction of the engagement piece 206. Therefore, when the engagement piece 206 is elastically deformed radially inward, the recess 224 of the atomization container 195 is slightly deformed radially inward.

  Thereafter, when the heater holder 196 is further pushed in, the engagement claws 207 move along the guide recess 198a. Thereafter, the engaging claws 207 ride on the end of the guide recess 198a (the end of the tank 191 on the engaging hole 198 side), and the restoring force of the engaging piece 206 and the restoring force of the recess 224 of the atomization container 195. Thus, the engagement claws 207 are inserted into the engagement holes 198 of the tank 191. Thereby, the heater holder 196 is fixed to the tank 191, and the assembly of the cartridge 11 is completed.

  Here, in a state where the heater holder 196 is fixed to the tank 191, the radial outer surface of the engagement piece 206 is covered by the peripheral wall 191b of the tank 191. Also, in order to release the engagement of one of the two engaging claws 207, for example, when trying to incline the tank 191 or the heater holder 196 so that the engaging claw 207 is disengaged from the engaging hole 198, the other engaging claw 207 will be pressed radially outward. Therefore, once engaged, it is difficult to release the engagement hole 198 and the engagement piece 206.

<How to use aspirator>
When using the aspirator 1 described above, the user presses the button 78. At this time, for example, by pressing the button 78 a plurality of times (for example, five times), the switch element 52 outputs a start preparation signal to the control unit mounted on the first substrate module 34.

  Subsequently, the user sucks the mouthpiece 23 or the tobacco capsule 12 while holding it. Then, the air in the holding unit 22 is sucked, whereby the pressure in the holding unit 22 becomes negative. When the pressure in the holding unit 22 becomes negative, the air in the pressure fluctuation chamber S1 is also sucked through the inside of the atomization container 195 of the cartridge 11 (in the atomization chamber M), the buffer space S3, and the communication port 51. The inside of the variable chamber S1 also has negative pressure. Specifically, 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 air inlet 216. The air that has flowed into the heater holder 196 passes through the air passage 226 and the atomization container 195, passes through the flow path pipe 197, and then enters the mouth of the user through the mouthpiece 23. When the pressure sensor 53 detects that the pressure in the pressure fluctuation chamber S1 has become less than, for example, a predetermined value, the pressure sensor 53 outputs a start signal to the control unit.

  The control unit having received the start signal energizes the heating unit 194 of the cartridge 11. In addition, when the inside of the holding unit 22 becomes negative pressure, new air is introduced into the holding unit 22 through the vent 131. Furthermore, new air is introduced into the atomization chamber M of the cartridge 11 (the opening chamber 203 of the tank 191) through the first air intake hole 209 formed in the heater holder 196 of the cartridge 11 and the air passage 226 of the atomization container 195. Be done.

  When the heating unit 194 is energized, the heating wire 205 generates heat. Then, the aerosol source of the liquid impregnated in the wick 204 through the mesh body 193 is heated and atomized. The atomized aerosol fills the atomization chamber M. Then, the atomized aerosol is sucked up to the mouthpiece 23 side through the flow path pipe 197 of the tank 191 together with the new air introduced into the atomization chamber M. Thereafter, the mixed gas of the atomized aerosol and the air enters the mouth of the user through the tobacco capsule 12. Thereby, the user can taste the flavor of tobacco.

<Function of cartridge>
By the way, in the cartridge 11, the aerosol source of the liquid stored in the liquid storage chamber 202 of the tank 191 is absorbed by the mesh body 193 and further absorbed by the wick 204. When the mesh body 193 or the wick 204 is saturated (when the liquid holding power is exceeded), the aerosol source of the liquid is transmitted along the inner peripheral surface from between the outer peripheral portion of the mesh body 193 and the inner peripheral surface of the peripheral wall 191 b in the tank 191 May leak to the heater holder 196 side.

Here, in the atomization container 195 located on the heater holder 196 side of the mesh body 193, a liquid reservoir portion 223 is formed on the outer peripheral surface. For this reason, the aerosol source of the liquid is prevented from being accumulated in the liquid reservoir 223 and leaking to the heater holder 196 side.
Specifically, in the present embodiment, the volume (space volume) of the liquid reservoir 223 is approximately 53.4 mm 3. Then, the remaining amount of liquid in the liquid storage chamber 202 of the tank 191 is set to 1/3, and the head space volume expansion rate (volume expansion rate of air in the remaining 2/3 space portion in the liquid storage chamber 202) is 6% Assuming that the air expansion in the liquid storage chamber 202 of the tank 191 expels an aerosol source of about 100 mm 3 of liquid from the liquid storage chamber 202. Among the extruded liquid aerosol sources, an aerosol source of about 20 to 30 mm 3 can be held by the mesh body 193 or the wick 204. Of the liquid aerosol source of about 100 mm 3, the remaining 70 to 80 mm 3 aerosol source accumulates in the liquid reservoir 223.

  Here, the liquid reservoir portion 223 is formed such that the gap between the outer peripheral surface of the cylindrical portion 217 and the peripheral wall 191b of the tank 191 becomes gradually narrower from the seal portion 222 toward the tip of the protrusion 219. That is, in the vicinity of the projecting portion 219 of the cylindrical portion 217, a narrow portion 279 is formed in which the gap between the projecting portion 219 and the peripheral wall 191b of the tank 191 is narrowed. For this reason, among the aerosol sources of the liquid pushed out from the liquid storage chamber 202 of the tank 191, the remaining aerosol source after the mesh body 193 and the wick 204 are saturated becomes easy to be absorbed by the narrow portion 279 The fluid flows to the reservoir portion 223 through the portion 279.

  That is, the aerosol source of the liquid stored in the liquid storage chamber 202 of the tank 191 is first absorbed by the mesh body 193 and then absorbed by the wick 204. After the mesh body 193 and the wick 204 are saturated, the aerosol source of the liquid is absorbed by the narrow portion 279 and is accumulated in the liquid reservoir 223.

  On the other hand, when the saturated state of the mesh body 193 is eliminated, the aerosol source of the liquid stored in the liquid reservoir 223 is sucked up through the narrow portion 279 (between the protrusion 219 and the peripheral wall 191b of the tank 191). Then, the aerosol source of the liquid is absorbed by the mesh body 193. That is, the aerosol source of the liquid stored in the liquid reservoir 223 is returned to the liquid storage chamber 202 of the tank 191 via the narrow portion 279. At this time, since the narrow portion 279 is covered (blocked) by the outer peripheral portion of the mesh body 193, the capillary force by the mesh body 193 also acts, and the liquid storage chamber 202 of the tank 191 is efficiently discharged. The aerosol source is refluxed.

  In addition, since two notches 222a are formed in the seal part 222 of the cylindrical part 217, the liquid reservoir 223 and the outside air, the notches 222a of the seal 222, and the engagement holes of the tank 191. Communication is made via a gap between 198 and the engagement piece 206 (the engagement claw 207) of the heater holder 196. As another example, the liquid reservoir portion 223 and the outside air may be communicated via the notch portion 222 a of the seal portion 222 and the first air inlet hole 209 of the heater holder 196. Therefore, no pressure difference occurs between the inside and the outside of the liquid reservoir 223. As a result, the aerosol source of the liquid is more efficiently returned to the liquid storage chamber 202 of the tank 191 while preventing the aerosol source of the liquid from unintentionally flowing out of the liquid reservoir 223 to the outside.

[effect]
As described above, in the present embodiment, the connection electrode portions 213b and 214b pass through the first imaginary circumference C1 passing through the first pin electrode 49a about the axis O and passing through the second pin electrode 49b about the axis O. Of the imaginary straight lines T1 formed in a region including both of the second virtual circumference C2 and connecting the pin electrodes 49, the connecting electrode portions 213b and 214b are circumferentially formed on the virtual straight line T1 (virtual straight line T2) in a predetermined direction. Insulating part 215 which divides by this was provided.
According to this configuration, it is suppressed that the two pin electrodes 49 come in contact with one connection electrode part 213b, 214b, or the one pin electrode 49 is placed across the two connection electrode parts 213b, 214b. The area of the connection electrode portions 213b and 214b can be secured above. Thus, the short circuit between the connection electrode parts 213b and 214b and the pin electrode 49 can be suppressed, and the reliability of the conduction between the connection electrode parts 213b and 214b and the pin electrode 49 can be secured.

In the present embodiment, the width in the circumferential direction around the axis Q in the insulating portion 215 (connection wall 211) is larger than the diameter (diameter) of each pin electrode 49.
According to this configuration, even if the pin electrode 49 is disposed on the insulating portion 215, it can be suppressed that the pin electrode 49 is disposed across the two connection electrode portions 213b and 214b. Thereby, a short circuit between the connection electrode portions 213b and 214b and the pin electrode 49 can be reliably suppressed.

In this embodiment, the connection electrode portions 213b and 214b are formed in a semicircular shape on both sides in the radial direction with the virtual straight line T2 interposed therebetween.
According to this configuration, the connection electrode portions 213b and 214b are radially larger than the region including both of the imaginary circumferences C1 and C2. Thus, dimensional variations and the like in the radial direction of the pin electrode 49 and the connection electrode portions 213b and 214b can be absorbed, so that the reliability of conduction between the connection electrode portions 213b and 214b and the pin electrode 49 can be secured.

In the present embodiment, one pin electrode 49 and one connection electrode portion 213b, 214b, and another pin electrode 49 and another connection electrode portion 213b, 214b overlap each other in plan view. An engagement recess 210 for restricting the rotation of the cartridge 11 is formed in the cartridge 11 (heater holder 196).
According to this configuration, the rotation of the cartridge 11 with respect to the power supply unit 21 can be restricted, and the conduction between the connection electrode portions 213 b and 214 b and the pin electrode 49 can be stably maintained.

In the present embodiment, the engagement recess 210 is configured to be recessed from the bottom portion 196 e of the heater holder 196.
According to this configuration, the power supply unit 21 is inserted by inserting the longitudinal engagement convex portion 101 into the engagement concave portion 210 in a state where the circumferential positions of the engagement concave portion 210 and the longitudinal engagement convex portion 101 coincide with each other. And the cartridge 11 can be approached in the axial direction. Thus, the pin electrode 49 and the connection electrode portions 213b and 214b can be reliably conducted to each other.

In this embodiment, on the bottom portion 196e side of the engagement recess 210, a tapered flat portion 210a is formed in which the circumferential width of the engagement recess 210 is gradually reduced as it is separated from the bottom 196e.
According to this configuration, the longitudinal engagement convex portion 101 can be easily guided into the engagement concave portion 210. This facilitates the mounting operation of the cartridge 11 to the power supply unit 21.

In this embodiment, a plurality of engaging recesses 210 are formed in the circumferential direction.
According to this configuration, in the process of rotating relative to the power supply unit 21 in a state where the cartridge 11 rides on the longitudinal engagement convex portion 101, the circumferential direction positions of the engagement concave portion 210 and the longitudinal engagement convex portion 101 coincide with each other. The rotation angle of the cartridge 11 can be reduced. This facilitates the mounting operation of the cartridge 11 to the power supply unit 21.

  The aspirator 1 of the present embodiment includes the cartridge 11 and the power supply unit 21 described above, and thus can provide the aspirator 1 with excellent reliability of conduction.

  In the present embodiment, by arranging the pin electrodes 49 in line symmetry with respect to the virtual straight line La, the manufacture of the power supply unit 21 becomes easy.

(First modification)
Next, a first modified example of the embodiment described above will be described. FIG. 24 is a plan view of a power supply unit 21 according to a modification of the embodiment. The present modification is different from the above-described embodiment in that the pin electrodes 500a and 500b are formed in the cartridge 11, and the connection electrode portions 501a and 501b are formed in the power supply unit 21. In addition, in the following description, about the structure corresponding to embodiment mentioned above, the same code | symbol may be attached | subjected and description may be abbreviate | omitted.
As shown in FIG. 24, in the suction device 1 of the present modification, the cartridge 11 is provided with a pair of pin electrodes 500a and 500b. The pin electrodes 500a and 500b axially project from the bottom (first electrode disposition surface) 196e of the heater holder 196 shown in FIG. 13, for example. Note that the pin electrodes 500a and 500b are disposed on the imaginary straight line T1 that is on both sides in the radial direction with respect to the axis line Q, passes the axis line Q, and extends in a tangential direction of the bottom portion 196e.

  The connection electrode portions 501a and 501b are formed, for example, on the base surface (second electrode disposition surface) 91a of the connection cap 80. The connection electrode portions 501a and 501b are at least formed on the rotation loci of the pin electrodes 500a and 500b when the power supply unit 21 and the cartridge 11 relatively rotate around the axis O (axis Q) in accordance with the embodiment described above. . That is, each of the connection electrode portions 501a and 501b has a first imaginary circumference C1 passing the first pin electrode 500a about the axis Q and a second imaginary circumference C2 passing the second pin electrode 500b about the axis Q. It is formed in the area | region containing both.

  In this modification, the connection electrode portions 501a and 501b are formed in a semicircular shape on both sides with the axis O interposed therebetween. Further, in the base surface 91a, a portion that passes through the axis O and is located on the imaginary straight line T2 extending in the radial direction constitutes an insulating portion 502 that divides the connection electrode portions 501a and 501b in the circumferential direction.

  Also in this modification, the same operation and effect as those of the above-described embodiment can be obtained.

(2nd modification)
Next, a second modification of the above-described embodiment will be described. FIG. 25 is a cross-sectional view of a combustor 1 according to a second modification of the embodiment. The present modification is different from the embodiment described above in that the insulating portion 510 protrudes from the bottom portion 196 e.
In the combustor 1 shown in FIG. 25, the insulating portion 510 protrudes from the bottom portion 196 e of the cartridge 11 toward the power supply unit 21 in the axial direction. The insulating portion 510 extends in the same radial direction as the sides 213 c and 214 c of the connection electrode portions 213 b and 214 b along the second imaginary straight line T 2 (see FIG. 10) described above. In addition, the insulation part 510 should just be arrange | positioned at least in the part which cross | intersects the imaginary circumferences C1 and C2 mentioned above in radial direction.

  The amount of protrusion of the insulating portion 510 in the axial direction from the bottom portion 196 e is preferably located closer to the power supply unit 21 than the pin electrode 49 when the cartridge 11 is mounted on the main body unit 10. Furthermore, it is preferable that the amount of projection of the insulating portion 510 be set to a length that does not abut on the base surface 91 a in a state where the cartridge 11 is mounted on the main body unit 10. In the present embodiment, when the cartridge 11 is not mounted, the amount of protrusion of the pin electrode 49 in the axial direction from the base surface 91 a is larger than the amount of protrusion of the insulating portion 510 from the bottom portion 196 e.

  In the peripheral wall 196b of the heater holder 196, an end portion located on the bottom portion 196e side constitutes a relief portion 514 whose outer diameter is smaller than an end portion located on the opposite side to the bottom portion 196e. Specifically, the relief portion 514 is axially recessed from the outer peripheral edge of the bottom portion 196 e and is opened to the outside in the radial direction. The relief portion 514 is formed over the entire circumference of the peripheral wall 196 b. The distance between the axis Q and the surface of the clearance portion 514 facing outward in the radial direction is shorter than the distance between the inner peripheral surface of the longitudinal engagement convex portion 101 described above and the axis O. That is, when the cartridge 11 is mounted on the main body unit 10, the clearance portion 514 accommodates the vertical engagement convex portion 101 while avoiding interference in the circumferential direction with the vertical engagement convex portion 101. Thereby, the cartridge 11 is stably held by the main body unit 10 by the longitudinal engagement convex portion 101 and the cartridge 11 being engaged in the radial direction. However, in the present modification, the vertical engagement convex portion 101 may not be provided.

According to this configuration, when the cartridge 11 is attached to the main body unit 10, even if the insulating portion 510 is in contact with the pin electrode 49 in the axial direction, the cartridge 11 is accompanied by the screwing operation of the mouthpiece 23 described above. And the mouthpiece 23 rotate together. As a result, the axial position of the cartridge 11 relative to the main unit 10 is permitted by shifting the circumferential positions of the insulating portion 510 and the pin electrode 49, and the connection electrode portions 213b and 214b are respectively guided to the corresponding pin electrodes 49. Be done.
On the other hand, when the cartridge 11 and the mouthpiece 23 rotate together with the screwing operation of the mouthpiece 23 in a state where the connection electrode portions 213b and 214b respectively contact the corresponding pin electrodes 49, the insulating portion 510 is a pin It contacts the electrode 49 in the circumferential direction. Thereby, the rotation of the cartridge 11 with respect to the power supply unit 21 is restricted.

  As described above, in the present modification, the cartridge 11 can be prevented from being attached to the main body unit 10 in a state where the pin electrode 49 and the insulating portion 510 abut in the axial direction. As a result, the reliability of conduction between the pin electrode 49 and the connection electrode portions 213b and 214b can be secured. In the present modification, even when the width in the circumferential direction of the insulating portion 510 is narrower than the axial diameter of the pin electrode 49, the pin electrode 49 is disposed across the two connection electrode portions 213b and 214b. Can be suppressed.
