The direction in which the spindle O extends is referred to as the spindle direction (Z-axis direction described above), the direction orthogonal to the spindle O is referred to as the radial direction, and the direction around the spindle O is referred to as the circumferential direction.

<Cartridge>
The cartridge 3 stores a liquid aerosol source and atomizes the liquid aerosol source. As shown in FIG. 5, the cartridge 3 is formed in a columnar shape and is accommodated inside the cartridge accommodating portion 10 from the cartridge insertion / removal port 10a described above.

FIG. 6 is a cross-sectional view taken along the line AA shown in FIG.
As shown in FIG. 6, the cartridge 3 includes a tank 21, a gasket 22, a mesh body 23, an atomizing container 24, a heating unit 25, and a heater holder 26. The tank 21 stores an aerosol source. The tank 21 has translucency, and the remaining amount of liquid in the aerosol source can be confirmed.

Here, "translucency" is a property of a substance through which light passes, which has an extremely high transmittance and allows light to pass through the substance in the same manner as "transparent" and "transparent". However, unlike "transparent", the shape of the other side cannot be clearly recognized through the material because the transmitted light is diffused or the transmission rate is low. That is, even frosted glass, milky white plastic, or the like has translucency.

The tank 21 is formed in a climax cylinder shape. A through hole 21b is formed in the top wall 21a of the tank 21. A flow path pipe 21c (also referred to as an inner peripheral wall) connected to the through hole 21b is vertically installed on the top wall 21a. The flow path tube 21c serves as a flow path for the atomized aerosol. The flow path pipe 21c is connected to the outer peripheral wall 21d of the tank 21 via a plurality of ribs 21e. The ribs 21e are arranged at equal intervals in the circumferential direction so as to be radial when viewed from the main axis direction (see FIG. 29 described later).

As shown in FIG. 6, the outer peripheral wall 21d of the tank 21 extends below (-Z side) from the lower end of the flow path pipe 21c. Two engaging holes 21f are formed in the vicinity of the lower end portion of the outer peripheral wall 21d. The two engagement holes 21f are for fixing the heater holder 26 to the tank 21. The two engaging holes 21f are arranged to face each other on both sides of the outer peripheral wall 21d with the main shaft O interposed therebetween. In the state where the cartridge 3 is housed in the cartridge housing part 10, the central axis of the cartridge 3 coincides with the spindle O of the cartridge housing part 10.

The gasket 22 is an annular plate member that covers the bottom of the annular space (liquid storage chamber 21 g) formed between the outer peripheral wall 21d of the tank 21 and the flow path pipe 21c. The gasket 22 positions the mesh body 23 and maintains the posture of the mesh body 23. A plurality of openings 22a are formed in the gasket 22. The openings 22a are arranged at equal intervals in the circumferential direction. The mesh body 23 is in contact with the liquid storage chamber 21g through the opening 22a of the gasket 22 and is wet.

The mesh body 23 is a porous and liquid-absorbent member. The mesh body 23 is formed of, for example, a cotton-based fiber material or a glass-based fiber. The mesh body 23 is also formed in an annular shape substantially the same as the gasket 22. That is, the flow path tube 21c can be inserted in the radial center of the mesh body 23. The mesh body 23 closes the opening 22a of the gasket 22 and forms a liquid storage chamber 21g inside the tank 21. A liquid aerosol source is stored in the liquid storage chamber 21 g.

The atomizing container 24 is made of an elastic member, for example, a resin material such as silicone resin. The atomizing container 24 is formed in the shape of a bottomed cylinder. The upper end opening edge of the peripheral wall 24a of the atomizing container 24 is in contact with the outer peripheral edge of the mesh body 23 in the main axis direction. That is, the mesh body 23 is sandwiched between the gasket 22 and the atomizing container 24. On the outer surface of the peripheral wall 24a of the atomizing container 24, a fitting portion 24b that fits into the inner surface of the outer peripheral wall 21d of the tank 21 is formed.

An atomization chamber 24c is formed inside the peripheral wall 24a of the atomization container 24. The atomization chamber 24c communicates with the flow path pipe 21c of the tank 21. An opening 24e is formed in the bottom wall 24d of the atomizing container 24. A heating unit 25 is arranged in the atomization chamber 24c.
The heating unit 25 is for atomizing a liquid aerosol source. The heating unit 25 includes a wick 25a connected to the mesh body 23 and a heating wire 25b for heating the wick 25a.

The wick 25a is a substantially columnar member that is porous and has liquid absorbency. The wick 25a is curved and deformed in a substantially U shape. More specifically, the wick 25a has two spindle extending portions extending in the spindle direction and a radial extending portion connecting the two spindle extending portions to each other. The two spindle-oriented extending portions are arranged so as to overlap each other in the X-axis direction (front-back direction in FIG. 6), and each is connected to the mesh body 23. As a result, the aerosol source absorbed by the mesh body 23 is sucked up by the wick 25a.

The heating wire 25b is spirally wound around the radial extension portion of the wick 25a. Both ends of the heating wire 25b extend toward the heater holder 26 side along the main axis direction. Both ends of the heating wire 25b are electrically connected to two flat electrodes 26h provided on the lower surface of the bottom wall 26d of the heater holder 26, respectively. When the heating wire 25b is energized through the two planar electrodes 26h, the wick 25a is heated. When the wick 25a is heated, the aerosol source absorbed by the wick 25a is atomized.

The heater holder 26 is formed in the shape of a bottomed cylinder. The peripheral wall 26a of the heater holder 26 is inserted outside the peripheral wall 24a of the atomizing container 24 and inside the outer peripheral wall 21d of the tank 21. The upper end opening edge of the peripheral wall 26a abuts on the fitting portion 24b of the atomizing container 24 in the main axis direction. At the upper end of the peripheral wall 26a, two engaging pieces 26b that engage with the two engaging holes 21f of the outer peripheral wall 21d of the tank 21 are formed. A gasket 22, a mesh body 23, and an atomizing container 24 are incorporated in this order between the tank 21 and the heater holder 26 in the main axis direction.

The lower side of the peripheral wall 26a of the heater holder 26 is exposed from the tank 21. The lower side of the peripheral wall 26a has substantially the same outer diameter as the outer peripheral wall 21d of the tank 21. Further, two intake holes 26c penetrating in the radial direction are formed on the lower side of the peripheral wall 26a. The two intake holes 26c are arranged to face each other on both sides of the peripheral wall 26a with the main shaft O interposed therebetween. The two intake holes 26c communicate the outside of the cartridge 3 (inside the cartridge accommodating portion 10) with the atomization chamber 24c. The bottom wall 26d of the heater holder 26 may also have an intake hole 26e penetrating in the main axis direction, but may not be formed. The intake hole 26e also communicates the outside of the cartridge 3 (inside the cartridge accommodating portion 10) with the atomization chamber 24c.

On the bottom wall 26d of the heater holder 26, a plate-shaped isolation wall 26f is erected in the main axis direction. Further, the isolation wall 26f extends in the radial direction, and both ends thereof are connected to the inner surface of the peripheral wall 26a. The bottom wall 26d is formed with two slits 26g penetrating in the main axis direction. The two slits 26g are arranged so as to sandwich the isolation wall 26f. Bent portions of the two plane electrodes 26h are inserted into the two slits 26g. The isolation wall 26f prevents short circuits at both ends of the heating wire 25b connected to the two planar electrodes 26h and the two planar electrodes 26h.

Returning to FIG. 5, three engaging groove portions 26i are formed on the bottom wall 26d of the heater holder 26. The three engaging groove portions 26i are arranged at equal intervals in the circumferential direction (at intervals of 120 ° in the circumferential direction). The engaging groove portion 26i is formed so as to open the outer side in the radial direction and the lower side in the main axis direction. The engaging groove portion 26i is formed in an isosceles trapezoidal shape when viewed from the radial direction, and has a tapered leg (slope) whose width in the circumferential direction gradually increases toward the lower side in the main axis direction. The number of the engaging groove portions 25i may be 2 or more, and is not limited to 3. For example, the number of engaging grooves 25i may be six.

<Flavor source container>
The flavor source container 4 houses the flavor source, and the flavor is added to the aerosol atomized by the cartridge 3. As the raw material piece constituting the flavor source, chopped tobacco or a molded product obtained by forming the tobacco raw material into granules can be used. Further, the flavor source may be composed of plants other than tobacco (for example, mint, Chinese herbs, herbs, etc.). Further, a fragrance such as menthol may be added to the flavor source. Further, the flavor source may be a carrier derived from a plant (cellulose or the like) or another carrier (including an inorganic carrier) on which the fragrance is supported. The flavor source container 4 is attached to the mouthpiece 11 of the main body unit 2.

As shown in FIG. 6, the flavor source container 4 includes a bottomed cylindrical container body 27 and a filter 28 that covers the opening of the container body 27. The peripheral wall 27a of the container body 27 is inserted inside the peripheral wall 11a1 of the mouthpiece 11. The upper side of the peripheral wall 27a of the container body 27 is exposed from the peripheral wall 11a1 of the mouthpiece 11. The upper side of the peripheral wall 27a has substantially the same outer diameter as the peripheral wall 11a1 of the mouthpiece 11. A step 27b is formed on the outer surface of the peripheral wall 27a so as to abut on the upper end opening edge of the peripheral wall 11a1 of the suction port portion 11.

A flavor source storage chamber 27c is formed inside the peripheral wall 27a of the container body 27. A plurality of micropores 27e penetrating in the main axis direction are formed on the bottom wall 27d of the container body 27.
The filter 28 is made of, for example, a non-woven fabric. The filter 28 is arranged inside the peripheral wall 27a of the container body 27. The filter 28 closes the opening of the container body 27, and the flavor source storage chamber 27c is formed inside the flavor source container 4.

In the embodiment, the main plate 41 extends in the thickness direction (X-axis direction). The first rib 42C and the second rib 42D extend in parallel with the longitudinal direction (Z-axis direction) of the main plate 41, and are arranged so as to face each other in the lateral direction (Y-axis direction) of the main plate 41. The sub-plate 42 is common to the first rib 42C and the second rib 42D in the sense of a "main plate intersection" extending from the end of the main plate 41 in a direction intersecting the plate surface of the main plate 41. However, it differs from the first rib 42C and the second rib 42D in that it holds parts such as the input device 15 and the display device 33. It was

As shown in FIG. 10, a plurality of substrate support pieces 41d are formed on the main plate 41 along the peripheral edge of the first plate surface 41a. The substrate support piece 41d supports the peripheral edge of the main substrate 31 (see FIG. 7) and forms a space between the substrate support piece 41d and the first plate surface 41a. As a result, the holder 30 can hold the main board 31 to which the electronic components are mounted on both sides.

On the first rib 42C (not shown, the same applies to the second rib 42D) surrounding the first plate surface 41a, a holding piece 42a that sandwiches the main substrate 31 supported by the substrate supporting piece 41d in the thickness direction (X-axis direction) is provided. It is formed. Further, a substrate support piece 41d is also formed in the vicinity of the second rib 42D in the same arrangement as the first rib 42C. The bottom wall 43b of the receiving portion 43 is also formed with a substrate support piece 43e that supports the main substrate 31 and a holding piece 43f that sandwiches the main substrate 31 in the thickness direction (X-axis direction).

Two engaging claws 41f for engaging the tray 44 described above with the opening 41c (see FIG. 7) of the main plate 41 are formed on the upper side (+ Z side) of the first plate surface 41a in the longitudinal direction. The two engaging claws 41f are arranged to face each other in the longitudinal direction (Z-axis direction) of the main plate 41 at the peripheral edge portion of the opening 41c. The tray 44 is formed in a rectangular shape extending in the Z-axis direction when viewed from the X-axis direction.

FIG. 12 is a cross-sectional view taken along the line BB shown in FIG. FIG. 12 shows a cross section passing through the two engaging claws 41f and the tray 44.
As shown in FIG. 12, the two engaging claws 41f are engaged with the peripheral portions of the tray 44 on the upper side (+ Z side) and the lower side (−Z side) in the longitudinal direction. The peripheral portions of the tray 44 not engaged with the two engaging claws 41f on the right side (+ Y side) and the left side (−Y side) in the lateral direction are placed on the first plate surface 41a.

The tray 44 is recessed on the −X side with respect to the first plate surface 41a of the main plate 41 in order to escape from the thickness of the vibrator 36 in the X-axis direction. The sub-board 32 is arranged in the recessed portion of the tray 44. The sub-board 32 is electrically connected to a connection terminal (not shown) of the vibrator 36. Further, the sub-board 32 is formed with an opening 32b for avoiding interference with the eccentric weight 36a of the vibrator 36. As shown in FIG. 12, it is not necessary to bring the sub-board 32 into contact with the vibrator 36, and only the connection terminals (not shown) of the vibrator 36 need be electrically connected to the sub-board 32.

The main board 31 extends in the Z-axis direction so as to overlap a part of the sub board 32 (tray 44) in the X-axis direction. That is, a part of the main board 31 is arranged so as to overlap with a part of the sub board 32 in the Z-axis direction. A connection terminal 32c is provided at a portion where the main board 31 and the sub board 32 overlap. The connection terminal 32c electrically connects the main board 31 and the sub board 32.

FIG. 13 is a perspective view showing a mounting structure of the vibrator 36 according to the embodiment.
As shown in FIG. 13, the first case 13A is formed with a mounting portion 13D for mounting the vibrator 36. The mounting portion 13D is formed on the facing surface 13a1 facing the second main surface portion 12A2 in the first main surface portion 12A1 in the first case 13A. The facing surface 13a1 is an inner wall surface facing the inside (-X side) of the outer case 12.

The mounting portion 13D has a mounting wall 13d1 that surrounds the main body portion (motor portion) of the vibrator 36, and a cutout portion 13d2 that cuts out a part of the mounting wall 13d1 and passes the rotation axis of the vibrator 36.

The cutout portion 13d2 is formed in the wall portion on the −Z side of the mounting wall 13d1. The eccentric weight 36a is arranged outside the mounting wall 13d1.

The main body of the vibrator 36 is fitted inside the mounting wall 13d1. An adhesive sheet or an adhesive may be interposed between the main body of the vibrator 36 and the first case 13A. In order to facilitate transmission of the vibration of the vibrator 36 to the first case 13A, a part or all of the main body of the vibrator 36 may be brought into direct contact with the first case 13A.

Returning to FIG. 10, the sub-plate 42 extends in a direction (X-axis direction) orthogonal to the plate surface (first plate surface 41a, second plate surface 41b) of the main plate 41. The sub-plate 42 of the present embodiment extends on both sides (+ X side and −X side) in a direction orthogonal to the plate surface of the main plate 41 (see FIG. 12). As a result, the cross section of the holder 30 becomes T-shaped, and the rigidity of the holder 30 can be increased.

As shown in FIG. 10, the sub-plate 42 is adjacent to the first sub-plate 42A provided on the first end side 41h1 of the end portion of the main plate 41 and the first end side 41h1 of the end portion of the main plate 41. It has a second sub-plate 42B provided on the second end side 41h2. The first end side 41h1 extends parallel to the XY plane at the upper end (+ Z side) in the longitudinal direction of the main plate 41.

The second end side 41h2 is tilted approximately 45 ° around the Z axis with respect to the XY plane from the left end (-Y side) of the first end side 41h1.

It can be said that the second end side 41h2 is a notch extending diagonally so as not to interfere with the rounded first corner portion 12C1 shown in FIG.

As shown in FIG. 11, the first sub-plate 42A provided on the first end side 41h1 and the second sub-plate 42B provided on the second end side 41h2 are connected to each other. By connecting the first sub-plate 42A and the second sub-plate 42B having a T-shaped cross section to each other, the rigidity of the holder 30 can be further increased. The first sub-plate 42A and the second sub-plate 42B are connected at an obtuse angle. As a result, the second subplate 42B can be slanted so as to face the rounded first corner portion 12C1 to hold the input device 15.

The angle formed by the first sub-plate 42A and the second sub-plate 42B is the angle formed by the first end side 41h1 and the second end side 41h2 in the main plate 41. That is, the first sub-plate 42A and the second sub-plate 42B are connected at an obtuse angle of approximately 135 °. The first sub-plate 42A and the second sub-plate 42B are not limited to a configuration in which they are connected at approximately 135 ° as long as they are connected within a range larger than 90 ° and smaller than 180 °.

As shown in FIG. 11, a positioning convex portion 42a1 is formed on the first sub-plate 42A. The positioning protrusion 42a1 is a protrusion for positioning the frame-shaped display device holder 33b (see FIG. 7) described above. As shown in FIG. 12, the positioning convex portion 42a1 forms the same plane (XY plane) as the display device holder 33b. This makes it easier to attach the adhesive sheet 45 that adheres the display device body 33a.

Further, as shown in FIG. 11, a sub-plate extending portion 42a2 is formed on the first sub-plate 42A. The sub-plate extending portion 42a2 is arranged at the end of the first sub-plate 42A on the side opposite to the end connected to the second sub-plate 42B. The sub-plate extending portion 42a2 extends to the + Y side of the second rib 42D. As shown in FIG. 8, the engaging claw 14b1 of the display cover 14 engages with the sub-plate extending portion 42a2.

As shown in FIG. 11, the wiring groove 42b1 and the substrate holding piece 42b2 are formed on the second sub-plate 42B. The substrate holding piece 42b2 is four L-shaped protrusions that hold the four corners of the switch substrate 15b (see FIG. 7) described above. The wiring groove 42b1 is a groove through which the wiring connecting the switch board 15b and the main board 31 is passed. The wiring groove 42b1 is formed so as to cross the region surrounded by the four substrate holding pieces 42b2.

Further, the sub-plate extending portion 42b3 is also formed on the second sub-plate 42B. The sub-plate extending portion 42b3 is arranged at the end of the second sub-plate 42B on the side opposite to the end connected to the first sub-plate 42A. The sub-plate extending portion 42b3 extends to the −Y side with respect to the first rib 42C. As shown in FIG. 8, another engaging claw 14b2 of the display cover 14 engages with the sub-plate extending portion 42b3.

FIG. 14 is a perspective view showing a mounting structure of the display cover 14 according to the embodiment.
As shown in FIG. 14, the display cover 14 has a convex curved shape on the upper side (+ Z side). The above-mentioned engaging claw 14b1 is arranged at the right end (+ Y side) of the display cover 14. The above-mentioned engaging claw 14b2 is arranged at the left end (—Y side) of the display cover 14 on the opposite side of the engaging claw 14b1.

The engaging claw 14b1 engages with the sub-plate extending portion 42a2 of the first sub-plate 42A. Further, the engaging claw 14b2 engages with the sub-plate extending portion 42b3 of the second sub-plate 42B. As shown in FIG. 8, the assembled display cover 14 is engaged with the holder 30 so as to straddle the first sub-plate 42A and the second sub-plate 42B from end to end.

As shown in FIG. 14, the display cover 14 is formed with a through hole 14a in which the switch button 15a of the input device 15 is arranged. The switch button 15a has a base portion 15a1 that abuts on the switch substrate 15b, and a columnar button portion 15a2 that protrudes from the base portion 15a1. The button portion 15a2 is arranged by inserting the through hole 14a.

The button portion 15a2 is formed of, for example, a hard resin material. An elastic body (spring or the like) (not shown) is provided inside the button portion 15a2 so that the button portion 15a2 returns to its original position when the button portion 15a2 is released. The button portion 15a2 may be an elastic body that can be elastically deformed by pressing. In that case, a rigid body that can be displaced by pressing (such as a prism that assists in pushing the switch substrate 15b) may be included inside the elastic body. An insertion hole 15a3 is formed on the peripheral surface of the button portion 15a2. The insertion hole 15a3 is formed at the root portion of the button portion 15a2 (near the connection portion of the button portion 15a2 with the base portion 15a1).

The switch holder 15c is formed in an annular shape that can be externally fitted to the button portion 15a2. The switch holder 15c is made of a flexible material that can be deformed in response to pressing of the button portion 15a2. The switch holder 15c may be made of an elastically deformable material. On the inner diameter side of the switch holder 15c, an inner diameter side protrusion piece 15c1 that can be inserted into the insertion hole 15a3 of the button portion 15a2 is formed. Further, on the outer diameter side of the switch holder 15c, two outer diameter side protrusion pieces 15c2 protruding on both sides in the X-axis direction are formed. The inner diameter side protrusion piece 15c1 and the two outer diameter side protrusion pieces 15c2 are 90 ° out of phase around the central axis of the switch holder 15c. The switch holder 15c covers the base portion 15a1 of the switch button 15a. Therefore, the base portion 15a1 can be hidden from the display cover 14 side.

Side walls 14c are vertically installed on both sides in the X-axis direction near the through hole 14a of the display cover 14. The side wall 14c is formed with two insertion holes 14c1 into which two outer diameter side projection pieces 15c2 of the switch holder 15c can be inserted. The components other than the switch holder 15c and the switch button 15a, that is, the switch board 15b of the input device 15, are assembled on the display cover 14 side. When the display cover 14 to which the switch holder 15c and the switch button 15a are assembled engages with the holder 30, the switch button 15a is placed on the switch board 15b and the input device 15 is assembled.

Returning to FIG. 11, the first rib 42C of the holder 30 extends in the longitudinal direction (Z-axis direction) along the −Y side end of the main plate 41. The upper end (+ Z side) of the first rib 42C in the longitudinal direction is connected to the second subplate 42B. By connecting the first rib 42C having a T-shaped cross section together with the main plate 41 to the second sub-plate 42B, the rigidity of the holder 30 can be further increased. A case fitting portion 42E is projected from the side surface of the first rib 42C facing the opposite side (−Y side) to the main plate 41.

The case fitting portion 42E is formed with a first fitting hole 42e1 and a second fitting hole 42e2. The first fitting hole 42e1 and the second fitting hole 42e2 are open on the −Y side. The first fitting hole 42e1 is arranged on the + X side of the case fitting portion 42E. The above-mentioned first case 13A is claw-fitted into the first fitting hole 42e1. The second fitting hole 42e2 is arranged on the −X side of the case fitting portion 42E. The above-mentioned second case 13B is claw-fitted into the second fitting hole 42e2.

Two case fitting portions 42E are formed so as to be separated from each other in the longitudinal direction of the first rib 42C. A set of a first fitting hole 42e1 and a second fitting hole 42e2 are formed in the case fitting portion 42E arranged on the lower side (−Z side) in the longitudinal direction of the first rib 42C. A plurality of sets of first fitting holes 42e1 and second fitting holes 42e2 are formed in the case fitting portion 42E arranged on the upper side (+ Z side) in the longitudinal direction of the first rib 42C so as to be separated from each other in the longitudinal direction. .. The case fitting portion 42E arranged on the + Z side is formed with a through hole 30a for screwing the holder 30.

The case fitting portion 42E arranged on the + Z side is provided with a sandwiched piece 42e3 that linearly partitions between the first fitting hole 42e1 and the second fitting hole 42e2. The sandwiched piece 42e3 is sandwiched between the first peripheral wall portion 12B1 of the first case 13A and the second peripheral wall portion 12B2 of the second case 13B. As shown in FIG. 1, the sandwiched piece 42e3 is not exposed on the outer surface 12b1 of the peripheral wall portion 12B of the outer case 12. That is, a step is formed inside the first peripheral wall portion 12B1 and the second peripheral wall portion 12B2 to sandwich the sandwiched piece 42e3.

As shown in FIG. 11, the second rib 42D of the holder 30 extends in the longitudinal direction (Z-axis direction) along the + Y-side end of the main plate 41. The upper end (+ Z side) of the second rib 42D in the longitudinal direction is connected to the first subplate 42A. By connecting the second rib 42D having a T-shaped cross section together with the main plate 41 to the first sub-plate 42A, the rigidity of the holder 30 can be further increased.

The second rib 42D has a branch portion 42D1 bent in an L shape toward the opposite side (+ Y side) of the main plate 41. The branch portion 42D1 is connected to the peripheral wall 43a of the receiving portion 43. As a result, the rigidity of the connecting portion between the main plate 41 and the receiving portion 43 can be increased. As shown in FIG. 10, a through hole 30a for screwing the holder 30 is formed in the connection portion between the main plate 41 and the receiving portion 43.

The second rib 42D is formed with a stepped notch 42d. The notch 42d has a first notch 42d1 and a second notch 42d2. The first notch 42d1 is formed from the + X-side end of the second rib 42D toward the −X-side end to the front of the main plate 41. The second notch 42d2 is arranged on the −Z side of the first notch 42d1. The second cutout portion 42d2 is formed from the + X side end portion of the second rib 42D toward the −X side end portion to the back surface side (position exceeding the second plate surface 41b) of the main plate 41 (position exceeding the second plate surface 41b). See FIG. 11).

The first notch 42d1 is formed in order to avoid interference with the optical path of the light source 52 (see FIG. 29 described later) provided on the main board 31. The light source 52 is, for example, an LED light or the like. As shown in FIG. 29, the second notch 42d2 is formed to avoid interference with the sensor holder 35 attached to the cartridge accommodating portion 10 and the sensor 34 held by the sensor holder 35.

FIG. 15 is a plan view of the holder 30 according to the embodiment. FIG. 16 is a cross-sectional view taken along the line CC shown in FIG.
As shown in FIG. 15, the receiving portion 43 of the holder 30 is formed in a bottomed cylindrical shape. The bottom wall 43b of the receiving portion 43 is formed with two insertion holes 43c for arranging two projecting electrodes 50 (see FIG. 7) inside the cartridge accommodating portion 10.

The two insertion holes 43c are arranged so as to be separated from each other in the Y-axis direction with the main shaft O interposed therebetween. The two insertion holes 43c penetrate the bottom wall 43b in the main axis direction (Z-axis direction). As shown in FIG. 10, an annular wall 43d is provided so as to project on the lower surface side (−Z side) of the bottom wall 43b. The annular wall 43d surrounds the two insertion holes 43c. The annular wall 43d is formed in a long hole shape in which both ends of two parallel lines extending in the Y-axis direction are connected by an arc in the bottom view.

As shown in FIG. 16, a step 43 g (annular receiving surface) that abuts with the cartridge accommodating portion 10 in the spindle direction (Z-axis direction) is formed inside the peripheral wall 43a of the receiving portion 43. The peripheral wall 43a on the lower side (−Z side) of the step 43g has a smaller diameter than the upper side (+ Z side) of the step 43g. As shown in FIG. 15, the peripheral wall 43a below the step 43 g has an inner diameter D1. The inner diameter D1 corresponds to the inner diameter of the cartridge accommodating portion 10.

On the upper surface side (+ Z side) of the bottom wall 43b of the receiving portion 43, an engaging protrusion 43h that engages with the engaging groove portion 26i (see FIG. 5) of the cartridge 3 described above is formed. The engaging groove portion 26i and the engaging protrusion portion 43h form a positioning mechanism 90 for positioning the cartridge 3 in the circumferential direction and the radial direction. Three engaging protrusions 43h are formed at equal intervals in the circumferential direction (at intervals of 120 ° in the circumferential direction). The number of engaging protrusions 43h is not limited to the same number of engaging groove portions 26i. The number of engaging protrusions 43h may be the same as or less than the number of engaging groove portions 26i.

As shown in FIG. 16, the engaging protrusion 43h has a curved surface shape protruding upward (+ Z side) in the main axis direction. That is, the width of the engaging protrusion 43h in the circumferential direction becomes smaller toward the upper side in the main axis direction. The engaging protrusion 43h may have an isosceles trapezoidal shape similar to that of the engaging groove 26i, or an isosceles triangle, as long as the width in the circumferential direction decreases toward the upper side in the main axis direction. .. Further, the engaging protrusion 43h may have an asymmetrical shape such as a right triangle. For example, when the engaging protrusion 43h is a right triangle, when the mouthpiece 11 is connected to the cartridge accommodating part 10, the side facing the rotation direction of the mouthpiece 11 may be the right angle side. This makes it difficult for the cartridge accommodating portion 10 to get over the engaging protrusion 43h when the suction port portion 11 is connected to the cartridge accommodating portion 10.

As shown in FIG. 15, the outer diameter D2 of the cartridge 3 accommodated inside the cartridge accommodating portion 10 is smaller than the inner diameter D1 of the cartridge accommodating portion 10. The gap generated between the inner diameter D1 of the cartridge accommodating portion 10 (that is, the inner diameter D1 below the step 43 g of the receiving portion 43) and the outer diameter D2 of the cartridge 3 is 2.6% of the inner diameter D1 of the cartridge accommodating portion 10. It should be big. As a result, the clearance between the cartridge accommodating portion 10 and the cartridge 3 becomes large, and it becomes easy to lure the engaging protrusion 43h into the engaging groove portion 26i when the cartridge 3 described later is set. The gap generated between the cartridge accommodating portion 10 and the cartridge 3 referred to here is calculated by the difference between the inner diameter D1 of the cartridge accommodating portion 10 and the outer diameter D2 of the cartridge 3. For example, when the inner diameter D1 is 11.8 mm and the outer diameter D2 is 11.5 mm, the gap is 0.3 mm. This gap corresponds to 2.54% of the inner diameter D1 and is excluded from the above conditions in this case.

More preferably, the gap generated between the inner diameter D1 of the cartridge accommodating portion 10 and the outer diameter D2 of the cartridge 3 is larger than 7.0% of the inner diameter D1 of the cartridge accommodating portion 10. As a result, the clearance between the cartridge accommodating portion 10 and the cartridge 3 becomes larger, and the engaging protrusion 43h can be easily attracted by the engaging groove portion 26i when the cartridge 3 described later is set. For example, when the inner diameter D1 is 12.4 mm and the outer diameter D2 is 11.5 mm, the gap is 0.9 mm. This gap corresponds to 7.26% of the inner diameter D1, and in this case, the above condition is satisfied.

It is preferable that the radial dimension D3 of the engaging protrusion 43h is larger than the gap generated between the cartridge accommodating portion 10 and the cartridge 3. The above two conditions are defined by the radial dimension D3 of the engaging protrusion 43h as follows. In the radial direction, the engaging protrusion 43h is the inner diameter D1 of the cartridge accommodating portion 10 from the inner peripheral wall of the cartridge accommodating portion 10 (that is, the inner peripheral wall of the peripheral wall 43a below the step 43 g) toward the inside of the cartridge accommodating portion 10. It is preferable that the dimension D3 is larger than 2.6% of the above. More preferably, the engaging protrusion 43h has a dimension D3 larger than 7.0% of the inner diameter D1 of the cartridge accommodating portion 10 from the inner peripheral wall of the cartridge accommodating portion 10 toward the inside of the cartridge accommodating portion 10 in the radial direction. It should be extended.

As shown in FIG. 15, an engaging protrusion 43i for positioning the cartridge accommodating portion 10 in the circumferential direction is formed on the step 43 g of the receiving portion 43. One engaging protrusion 43i is formed on the inner wall surface on the front side (+ X side) of the peripheral wall 43a of the receiving portion 43. The engaging protrusion 43i does not project radially inward from the step 43g of the receiving portion 43, and is formed to the same degree of protrusion as the peripheral wall 43a below the step 43g. As shown in FIG. 16, the engaging protrusion 43i has a curved surface shape protruding upward (+ Z side) in the main axis direction, similarly to the engaging protrusion 43h. That is, the width of the engaging protrusion 43i in the circumferential direction becomes smaller toward the upper side in the main axis direction.

<Cartridge housing>
FIG. 17 is a front view of the cartridge accommodating portion 10 according to the embodiment. FIG. 18 is a right side view of the cartridge accommodating portion 10 according to the embodiment. FIG. 19 is a left side view of the cartridge accommodating portion 10 according to the embodiment. FIG. 20 is a cross-sectional view taken along the line DD shown in FIG.
As shown in FIG. 17, the cartridge accommodating portion 10 is a cylindrical member and extends in the main axis direction (Z-axis direction). The cartridge accommodating portion 10 is made of a metal tubular member while the outer case 12 and the holder 30 are made of resin.

A cartridge insertion / removal port 10a is formed at the end of the cartridge accommodating portion 10 on the upper side (+ Z side) in the main axis direction. On the other hand, an engaging groove portion 10b that engages with the above-mentioned engaging protrusion 43i is formed at an end portion of the cartridge accommodating portion 10 on the lower side (−Z side) in the main axis direction. One engaging groove portion 10b is formed on the front side (+ X side) of the lower end portion of the cartridge accommodating portion 10.

As shown in FIG. 18, a through hole 10c and two air communication holes 10e are formed on the right side (+ Y side) of the peripheral surface of the cartridge accommodating portion 10. A cartridge accommodating portion side projection 17C, which will be described later, provided in the cover member 17 (see FIG. 7) is inserted into the through hole 10c (see FIG. 29, which will be described later). The two air communication holes 10e communicate with the two air holes 19 provided in the cover member 17 (see FIG. 29 described later).

As shown in FIG. 18, the through hole 10c is an elongated hole extending in the main axis direction (Z-axis direction). A rectangular groove 10c1 is formed at the end edge of the through hole 10c on the −X side. The rectangular groove 10c1 asymmetrics the shape of the through hole 10c in the X-axis direction in order to prevent an error in assembling the cover member 17 to the cartridge accommodating portion 10. The two air communication holes 10e are arranged so as to sandwich the through hole 10c in the X-axis direction. The air communication hole 10e is formed larger than the air hole 19 as shown in FIG. 29, which will be described later. This makes it possible to prevent non-communication between the air hole 19 and the air communication hole 10e and misalignment such that the flow path area is narrowed. That is, when assembling the main body unit 2, the air holes 19 are less likely to be closed.

As shown in FIG. 19, another through hole 10d is also formed on the left side (-Y side) of the peripheral surface of the cartridge accommodating portion 10. A cartridge accommodating portion side projection 35D, which will be described later, provided in the sensor holder 35 (see FIG. 7) is inserted into the through hole 10d (see FIG. 29, which will be described later). The through hole 10d is an elongated hole extending in the main axis direction (Z-axis direction). The through hole 10d is arranged diagonally to the left front side (+ X side) of the cartridge accommodating portion 10, and as shown in FIG. 29 described later, with respect to the through hole 10c on the right side (+ Y side), the spindle O is the center. There is no point-symmetrical positional relationship.

As shown in FIG. 20, in the cartridge accommodating portion 10, the insert ring 10A is internally fitted by press fitting on the upper side (+ Z side) in the main axis direction with respect to the through hole 10c and the through hole 10d. The insert ring 10A is a resin tubular member. The insert ring 10A is formed with a suction port connection portion 10B for connecting the suction port portion 11 (see FIG. 5) to the cartridge insertion / removal port 10a. A recess 10f is formed on the inner wall surface of the cartridge accommodating portion 10 on the upper side (+ Z side) in the main axis direction so that the inner diameter is not reduced by the inner fitting of the insert ring 10A.

Two mouthpiece connection portions 10B are formed at equal intervals (180 °) in the circumferential direction of the insert ring 10A. The mouthpiece connection portion 10B is a groove (notch) formed in the insert ring 10A. The mouthpiece connecting portion 10B has a first groove portion 10b1, a second groove portion 10b2, and a third groove portion 10b3. The width of the first groove portion 10b1 increases in the circumferential direction toward the upper side (+ Z side) in the main axis direction. The second groove portion 10b2 extends downward (−Z side) in the main axis direction with a constant width from the lower end of the first groove portion 10b1. The third groove portion 10b3 is bent 90 ° in the circumferential direction from the lower end of the second groove portion 10b2, and rotates the insert ring 10A approximately 1/4 in a constant width.

<Mouthpiece>
FIG. 21 is a right side view of the mouthpiece portion 11 according to the embodiment. FIG. 22 is a cross-sectional view taken along the line EE shown in FIG. 21.
As shown in FIG. 21, the mouthpiece 11 has a protrusion 11b1 that engages with the mouthpiece connection portion 10B of the cartridge accommodating portion 10 described above. The mouthpiece 11 includes a resin mouthpiece main body 11A and, as shown in FIG. 22, a metal cylinder 11B having two protrusions 11b1 formed therein.

As shown in FIG. 22, the mouthpiece main body 11A is formed in a bottomed cylindrical shape. The above-mentioned flavor source container 4 (see FIG. 6) is inserted inside the peripheral wall 11a1 of the mouthpiece main body 11A. On the outer surface of the peripheral wall 11a1, a flange portion 11a2 extending radially outward is provided in an annular shape. As shown in FIG. 6, the flange portion 11a2 abuts on the upper end opening edge of the cartridge accommodating portion 10 (opening edge of the cartridge insertion / removal port 10a) in the spindle direction (Z-axis direction).

A through hole 11a4 penetrating in the main axis direction is formed in the bottom wall 11a3 of the mouthpiece main body 11A. A cartridge contact portion 60 is internally fitted in the through hole 11a4 (see FIG. 6). The cartridge contact portion 60 is an elastic body formed of a resin material such as a silicone resin. The cartridge contact portion 60 includes a first ring portion 60a, a cylindrical portion 60b, and a second ring portion 60c.

The first ring portion 60a is arranged on the upper side (+ Z side) in the main axis direction from the bottom wall 11a3 of the mouthpiece portion main body 11A. The first ring portion 60a has a larger outer diameter than the through hole 11a4 and extends to the inner wall surface of the peripheral wall 11a1 of the mouthpiece main body 11A. The first ring portion 60a abuts on the bottom wall 27d of the flavor source container 4 inside the peripheral wall 11a1. The side of the first ring portion 60a facing the bottom wall 27d of the flavor source container 4 may be a flat surface, or a groove may be formed according to the shape of the legs of the bottom wall 27d. The first ring portion 60a serves as a non-slip in the circumferential direction of the flavor source container 4 and a seal chamber of the fine holes 27e of the flavor source container 4. The first ring portion 60a does not have to come into contact with the bottom wall 27d of the flavor source container 4. In that case, a seal portion that prevents the introduction of outside air can be formed at the contact portion between the flavor source container 4 and the mouthpiece portion 11 at the step 27b. The cylindrical portion 60b is arranged by inserting the through hole 11a4 of the bottom wall 11a3. The cylindrical portion 60b connects the inner diameter side of the first ring portion 60a and the inner diameter side of the second ring portion 60c in the main axis direction.

The second ring portion 60c is arranged on the lower side (-Z side) in the main axis direction from the bottom wall 11a3 of the mouthpiece portion main body 11A. The second ring portion 60c has a larger outer diameter than the through hole 11a4 and extends to the inner wall surface of the tubular body 11B. The second ring portion 60c is formed with an annular protrusion 61 projecting downward in the main axis direction toward the cartridge 3. Due to the annular projection 61, the contact of the second ring portion 60c with the cartridge 3 is no longer a planar contact, the contact pressure with respect to the cartridge 3 increases, and the frictional force in the circumferential direction and the pressing force in the spindle direction, which will be described later, are likely to occur.

A communication hole 62 is formed at the center of the first ring portion 60a, the cylindrical portion 60b, and the second ring portion 60c. The communication hole 62 communicates the through hole 21b of the tank 21 of the cartridge 3 described above with the fine hole 27e of the flavor source container 4. The annular projection 61 of the second ring portion 60c is formed in a double annular shape. The annular protrusion 61 abuts on the top wall 21a of the tank 21 around the through hole 21b of the cartridge 3, so that a highly airtight double seal can be formed.

Returning to FIG. 22, the tubular body 11B is fitted onto the peripheral wall 11a1 below the flange portion 11a2 of the mouthpiece main body 11A by press fitting. Two protrusions 11b1 are arranged on the peripheral surface of the tubular body 11B at equal intervals (180 °) in the circumferential direction. The tubular body 11B extends downward (−Z side) in the main axis direction from the peripheral wall 11a1 of the mouthpiece main body 11A. The above-mentioned second ring portion 60c is arranged in the space below the bottom wall 11a3 surrounded by the tubular body 11B. As shown in FIG. 6, the inner diameter of the tubular body 11B is larger than the outer diameter of the cartridge 3. As a result, even if the mouthpiece portion 11 is strongly pushed toward the cartridge 3 and the second ring portion 60c is elastically deformed so as to be crushed in the main axis direction in a state as shown in FIG. 37, which will be described later, the cylinder body 11B remains in the cartridge. It is designed not to interfere with 3.

<Main board>
FIG. 23 is a perspective view of the main substrate 31 according to the embodiment. FIG. 24 is a perspective view showing a state in which the protrusion electrode cover 51 is removed from the protrusion electrode 50 of the main substrate 31 according to the embodiment.
As shown in FIG. 23, the main substrate 31 has a plate shape extending along a YZ plane, and has a first plate surface 31a facing the front side (+ X side) and a first plate surface 31a facing the rear side (−X side). It has two plate surfaces 31b. The second plate surface 31b of the main board 31 illuminates the protrusion electrode 50 inserted into the cartridge storage chamber, which is an internal space formed by the cartridge housing portion 10 and the receiving portion 43 described above, and the inside of the cartridge housing portion 10. The light source 52 and the light source 52 are arranged. The protruding electrode 50 may reach the inside of the cartridge accommodating portion 10 in the cartridge accommodating chamber, or may reach only the inside of the receiving portion 43. Further, when the receiving portion 43 has a flat plate shape, the protruding electrode 50 can easily reach the inside of the cartridge accommodating portion 10.

Here, the "main board" means the largest board among the boards housed inside the outer case 12. The main board 31 is larger than the sub board 32 and the switch board 15b of the input device 15 described above. When only one substrate is housed inside the outer case 12, the substrate is the "main substrate". When two boards of the same size are housed inside the outer case 12, a board provided with an electronically controlled arithmetic unit such as a CPU or a microcomputer is referred to as a "main board".

The main board 31 has a first portion 31A extending in the main axis direction (Z-axis direction) and a second portion 31B extending in a direction intersecting the first portion 31A. The second portion 31B extends in the Y-axis direction orthogonal to the direction in which the first portion 31A extends. That is, the main substrate 31 is formed in an L shape when viewed from the X-axis direction. The second portion 31B does not necessarily have to be bent at a right angle to the first portion 31A as long as it can extend to the lower side (−Z side) of the receiving portion 43 shown in FIG. That is, the shape of the main board 31 is not limited to the L shape.

The first portion 31A is a portion that overlaps with the main plate 41 of the holder 30 shown in FIG. The first portion 31A is held on the main plate 41 by the substrate support piece 41d and the holding piece 42a. The first portion 31A extends in the main axis direction along the main plate 41. That is, the first portion 31A extends in parallel with the cartridge accommodating portion 10. The light source 52 is arranged on the cartridge accommodating portion 10 side (+ Y side) of the first portion 31A (see FIG. 23).

The second portion 31B is a portion extending from the main plate 41 of the holder 30 shown in FIG. 10 to the receiving portion 43 side (+ Y side). The second portion 31B is held by the substrate support piece 43e and the holding piece 43f of the bottom wall 43b of the receiving portion 43. The second portion 31B is arranged so as to face the receiving portion 43 (that is, the end portion of the cartridge accommodating portion 10) in the spindle direction (Z-axis direction). In other words, the second portion 31B is arranged side by side with the receiving portion 43 in the main axis direction. The projecting electrode 50 is arranged on the side (+ Z side) facing the receiving portion 43 of the second portion 31B (see FIG. 23).

As shown in FIG. 24, the protruding electrode 50 is supported by a pedestal portion 50A provided on the second plate surface 31b of the main substrate 31. The pedestal portion 50A supports the protruding electrode 50 so as to be parallel to the plate surface (first plate surface 31a, second plate surface 31b, that is, the YY plane) of the main substrate 31. That is, the two + and-terminals of the projecting electrode 50 supported by the pedestal portion 50A extend in parallel along the YZ plane.

The main substrate 31 is provided with a protruding electrode cover 51 that covers a portion where the protruding electrode 50 is provided. The portion where the protrusion electrode 50 is provided includes the pedestal portion 50A. Specifically, the portion where the protrusion electrode 50 is provided includes the pedestal portion 50A, the root portion of the protrusion electrode 50, and the peripheral region of the pedestal portion 50A on the second plate surface 31b. The projectile electrode cover 51 is formed in a substantially box shape with an opening on the side facing the second plate surface 31b. The projectile electrode cover 51 has a cover end wall 51a arranged on the −X side of the pedestal portion 50A, and a cover peripheral wall 51b that surrounds both sides of the pedestal portion 50A in the Y-axis direction and both sides in the Z-axis direction. ..

Two through holes 51c are formed in the wall portion on the + Z side of the cover peripheral wall 51b through which the protruding electrode 50 is arranged. The tip portion of the projecting electrode 50 is urged to the + Z side by a spring member (not shown) housed in the root portion of the projecting electrode 50, and is freely displaceable in the Z-axis direction. That is, the protruding electrode 50 extends toward the cartridge 3 and is displaced in the −Z direction when the cartridge 3 is inserted. Even in that state, the protruding electrode 50 is urged in the + Z direction, so that contact with the cartridge 3 can be ensured. The inner wall surface of the through hole 51c is in close contact with a portion that does not constrain the displacement of the tip portion of the protrusion electrode 50, for example, the outer periphery of the root portion of the protrusion electrode 50 in the present embodiment.

FIG. 25 is a cross-sectional view taken along the line FF shown in FIG.
As shown in FIG. 25, the protruding electrode cover 51 is in contact with the receiving portion 43 of the holder 30 in which the insertion hole 43c is formed. The protruding electrode 50 is inserted into the insertion hole 43c. The + Z side wall portion of the cover peripheral wall 51b of the projectile electrode cover 51 is in contact with the annular wall 43d of the bottom wall 43b of the receiving portion 43 in the main axis direction. The projectile electrode cover 51 is made of a silicone resin. The wall portion on the + Z side of the cover peripheral wall 51b is elastically deformed due to contact with the annular wall 43d.

A substrate contact portion 43j is provided on the bottom wall 43b of the receiving portion 43. The substrate contact portion 43j is arranged on the + X side of the annular wall 43d. The board contact portion 43j is provided so as to project from the bottom wall 43b of the receiving portion 43 toward the −Z side, and is in contact with the main board 31 in the main axis direction. As shown in FIG. 10, the substrate contact portion 43j is arranged between the substrate support piece 43e and the holding piece 43f provided on the bottom wall 43b, and extends linearly in the Y-axis direction.

As shown in FIG. 25, the annular wall 43d extends to the −Z side with respect to the substrate contact portion 43j. The elastic deformation of the protruding electrode cover 51 due to the annular wall 43d is limited to a certain amount by the contact between the substrate contact portion 43j and the main substrate 31. That is, the contact pressure between the annular wall 43d and the projecting electrode cover 51 can be managed by the substrate contact portion 43j. Therefore, the sealing property between the annular wall 43d and the projecting electrode cover 51 can be ensured without excessively pressing the projecting electrode cover 51 against the annular wall 43d.

The projectile electrode cover 51 is provided on the main substrate 31 together with the projectile electrode 50. That is, the protruding electrode cover 51 is not held by a structure other than the main substrate 31 (for example, the outer case 12 or the like). Further, as shown in FIG. 25, the protruding electrode cover 51 is incorporated in the outer case 12 in a non-contact state. As a result, the protruding electrode cover 51 can be prevented from coming into contact with the outer case 12 and being deformed or misaligned, so that the sheath property is not impaired.

<Cover member>
FIG. 26 is a view of the cover member 17 according to the embodiment as viewed from the outside in the radial direction. FIG. 27 is a view of the cover member 17 according to the embodiment as viewed from the inside in the radial direction. FIG. 28 is a perspective view of the cover member 17 according to the embodiment.
As shown in FIG. 26, the cover member 17 is provided with a main body case side protrusion 17A on the outer side in the radial direction, that is, on the right side (+ Y side) facing the main body case 13. As shown in FIG. 2, the main body case side protrusion 17A is inserted into the opening 13a of the main body case 13. The cover member 17 has translucency, and the remaining amount of the aerosol source of the cartridge 3 housed in the cartridge housing portion 10 can be confirmed through the main body case side projection 17A.

The main body case side protrusion 17A is formed in a long hole shape extending in the main axis direction (Z-axis direction) like the opening 13a of the main body case 13. The main body case side protrusion 17A is slightly smaller than the opening 13a. An air inlet 18 is formed in the gap between the main body case side protrusion 17A and the opening 13a. A part of the main body case side protrusion 17A may be in contact with the inner wall surface of the opening 13a. The air inlet 18 is an inlet of an intake flow path that takes in outside air into the inside of the outer case 12 by suction of the user.

The air inlet 18 is formed in an annular shape along the opening edge (also referred to as the peripheral edge of the main body case side protrusion 17A) of the opening portion 13a of the main body case 13. The size of the air inlet 18 should be such that it cannot be completely blocked by the user's finger. For example, the dimension of the air inlet 18 in the spindle direction (Z-axis direction) may be equal to or larger than the first finger indirect width (for example, 2.0 cm or more) of the average thumb of a general adult. Further, the distance between the two slits extending parallel to the main axis of the air inlet 18 in the X-axis direction may be greater than or equal to the indirect width of the first finger of the average thumb of a general adult.
The air inlet 18 may have only one or two slits extending in parallel in the main axis direction as long as the size is not blocked by the user's finger. That is, the air inlet 18 may be formed in a slit shape along the opening edge of the opening portion 13a of the main body case 13.

As shown in FIG. 28, the cover member 17 has a plate portion 17B that supports the main body case side protrusion 17A. The plate portion 17B is arranged so as to overlap the inside of the main body case 13. The plate portion 17B is interposed between the main body case 13 and the cartridge accommodating portion 10. The cartridge accommodating portion 10 side (−Y side) of the plate portion 17B is curved along the peripheral surface of the cartridge accommodating portion 10. Further, the main body case 13 side (+ Y side) of the plate portion 17B is curved along the inner wall surface of the peripheral wall portion 12B (see FIG. 2). The curved shape (curvature, etc.) of the plate portion 17B is different between the cartridge accommodating portion 10 side (−Y side) and the main body case 13 side (+ Y side).

Further, the upper side (+ Z) in the main axis direction of the plate portion 17B on the main body case 13 side is curved along the inner wall surface of the second corner portion 12C2 of the peripheral wall portion 12B. That is, the thickness of the plate portion 17B decreases toward the upper side (+ Z) in the main axis direction. The above-mentioned air hole 19, the air groove 70, and the case fitting hole 17b1 are formed in the plate portion 17B. Two air holes 19 are formed so as to sandwich the main body case side protrusion 17A in the X-axis direction.

FIG. 29 is a cross-sectional view taken along the line GG shown in FIG.
As shown in FIG. 29, the air holes 19 are arranged at locations where the cover member 17 and the main body case 13 overlap. That is, the air holes 19 are arranged inside the main body case 13 and are covered with the main body case 13. Therefore, the air hole 19 cannot be visually recognized from the outside of the main body case 13. Further, the air hole 19 cannot be directly closed with a finger unless the main body case 13 is removed.

The air hole 19 allows fluid communication between the air inlet 18 and the inside of the cartridge accommodating portion 10. The air hole 19 is a main flow path of an intake flow path that takes in outside air inside the outer case 12. The air hole 19 of the present embodiment communicates with the air communication hole 10e formed in the cartridge accommodating portion 10, and allows the air inlet 18 and the inside of the cartridge accommodating portion 10 to communicate with each other in a short distance. When the air communication hole 10e is not formed, the air taken into the inside of the outer case 12 from the air hole 19 flows into the inside of the cartridge accommodating portion 10 through all the gaps of the cartridge accommodating portion 10.

Returning to FIG. 26, two sets of case fitting holes 17b1 are formed in the plate portion 17B on the upper side and the lower side of the air hole 19 by sandwiching the main body case side protrusion 17A in the X-axis direction. The main body case 13 is claw-fitted into a total of four case fitting holes 17b1. Specifically, the fitting claw 13E of the first case 13A (see FIG. 34 described later) is claw-fitted into the two case fitting holes 17b1 arranged on the + X side of the main body case-side protrusion 17A. Further, the fitting claw 13I (see FIG. 35 described later) of the second case 13B is claw-fitted into the two case fitting holes 17b1 arranged on the −X side of the main body case-side protrusion 17A.

The air groove 70 forms a space connecting between the air inlet 18 and the air hole 19. As shown in FIG. 28, the air groove 70 has an annular groove portion 71 and two stepped groove portions 72. The annular groove portion 71 is formed in an annular shape around the main body case side protrusion 17A in the plate portion 17B. The annular groove portion 71 is recessed on the −Y side with respect to the outer surface of the plate portion 17B on the main body case 13 side (+ Y). As shown in FIG. 29, the width of the annular groove portion 71 is preferably larger than the width of the air inlet 18 (distance from the inner peripheral edge to the outer peripheral edge).

The two step groove portions 72 are formed on the + X side edge and the −X side edge of the annular groove 71. The step groove portion 72 has a lower bottom surface than the annular groove portion 71. That is, the step groove portion 72 is recessed on the −Y side with respect to the annular groove portion 71. An air hole 19 is formed on the bottom surface of the step groove portion 72. The bottom surface of the step groove portion 72 is formed wider than the opening area of the air hole 19.

As shown in FIG. 27, the cover member 17 has a cartridge accommodating portion side projection 17C on the cartridge accommodating portion 10 side (−Y side) of the plate portion 17B. The cartridge accommodating portion side protrusion 17C is inserted into a through hole 10c (see FIG. 18) formed on the peripheral surface of the cartridge accommodating portion 10. The cartridge accommodating portion side projection 17C is formed in the shape of an elongated hole extending in the main axis direction (Z-axis direction) like the through hole 10c of the cartridge accommodating portion 10.

Further, as shown in FIG. 27, the cover member 17 has a cover positioning protrusion 17D on the cartridge accommodating portion 10 side (−Y side) of the plate portion 17B. The cover positioning projection 17D is arranged on the −X side of the cartridge accommodating portion side projection 17C. The cover positioning protrusion 17D is a rectangular protrusion extending in the X-axis direction. The cover positioning protrusion 17D is inserted into the rectangular groove 10c1 of the cartridge accommodating portion 10 shown in FIG. This makes it possible to prevent an error in assembling the cover member 17 to the cartridge accommodating portion 10.

<Sensor holder>
FIG. 30 is a view of the sensor holder 35 according to the embodiment as viewed from the outside in the radial direction. FIG. 31 is a view of the sensor holder 35 according to the embodiment as viewed from the inside in the radial direction. FIG. 32 is a perspective view of the sensor holder 35 according to the embodiment.
As shown in FIG. 32, the sensor holder 35 has a curved plate portion 35A shaped along the peripheral surface of the cartridge accommodating portion 10. As shown in FIG. 29, the curved plate portion 35A is in close contact with the peripheral surface of the cartridge accommodating portion 10 via the adhesive sheet 48. The curved plate portion 35A is arranged in a narrow gap between the cartridge accommodating portion 10 and the holder 30.

As shown in FIG. 29, the sensor holder 35 is provided with a holder-side protrusion 35B protruding toward the holder 30 on the outer surface of the curved plate portion 35A on the opposite side of the cartridge accommodating portion 10. The holder side protrusion 35B is formed in a cylindrical shape. The sensor 34 is held inside the holder side protrusion 35B. The holder side protrusion 35B (and the sensor 34) is arranged so as to be inserted into the second notch 42d2 of the second rib 42D of the holder 30.

<Appearance of the main unit>
FIG. 36 is a front view of the main body unit 2 with the mouthpiece 11 according to the embodiment removed.
As shown in FIG. 36, the main body unit 2 includes a cartridge accommodating portion 10 having a cartridge insertion / removal port 10a protruding from the outer case 12. That is, a part of the cartridge accommodating portion 10 including the cartridge insertion / removal port 10a protrudes from the outer case 12, so that the place where the cartridge 3 is inserted / removed is easily visible.

A part of the cartridge accommodating portion 10 protruding from the outer case 12 includes a suction port connection portion 10B (see FIGS. 6 and 20) for connecting the suction port portion 11 to the cartridge insertion / removal port 10a. That is, at least a part of the mouthpiece connection portion 10B protrudes from the outer case 12. As a result, the first groove portion 10b1 of the suction port connection portion 10B and the like can be easily seen from the cartridge insertion / removal port 10a.

The exterior case 12 is provided with a raised portion 12D on the upper side (+ Z side) in the main axis direction. The cartridge accommodating portion 10 projects upward in the main axis direction from the deformation transient portion 12D1 of the raised portion 12D. The deformation transient portion 12D1 is a portion from the second corner portion 12C2 to the top portion P of the raised portion 12D. It can be said that the deformation transient portion 12D1 is a portion in which the dimension of the outer case 12 in the Z-axis direction increases from the second corner portion 12C2 to the top portion P of the raised portion 12D. Further, it can be said that the deformation transient portion 12D1 is a portion inclined with respect to the main axis direction. The deformation transient portion 12D1 is not limited to the curved surface as shown in FIG. 36, and may be a slope.

The deformation transient portion 12D1 forms a portion (+ Y side) that is largely exposed from the outer case 12 and a portion (-Y side) that is slightly exposed in the cartridge accommodating portion 10. The visibility of the cartridge accommodating portion 10 can be ensured in the greatly exposed portion of the cartridge accommodating portion 10. In the small exposed portion of the cartridge accommodating portion 10, the outer case 12 can secure an area for protecting the cartridge accommodating portion 10. Further, since the contact length between the edge of the outer case 12 and the peripheral surface of the cartridge accommodating portion 10 becomes long, it becomes easy to secure the connection strength when the two are bonded to each other.

As shown in FIG. 36, the cartridge insertion / removal port 10a is arranged at a position below the top P of the raised portion 12D in the main axis direction (Z-axis direction) in which the cartridge accommodating portion 10 extends. That is, the cartridge insertion / removal port 10a is lowered to the lower side (−Z side) in the main axis direction with respect to the top portion P of the raised portion 12D. For example, when the main body unit 2 is turned upside down and dropped, the raised portion 12D comes into contact with the ground or the like before the cartridge insertion / removal port 10a to protect the cartridge insertion / removal port 10a.

The raised portion 12D has a deformation transient portion 12D1 in which the input device 15 is arranged on the opposite side (−Y side) sandwiching the deformation transient portion 12D1 and the top portion P. The input device 15 is arranged at a position below the top P of the raised portion 12D in the main axis direction (Z-axis direction) in which the cartridge accommodating portion 10 extends. For example, when the main body unit 2 is turned upside down and dropped, the raised portion 12D comes into contact with the ground or the like before the input device 15 to prevent the input device 15 from malfunctioning.

The input device 15 is arranged so as to face an acute angle direction with respect to the main shaft O of the cartridge accommodating portion 10 passing through the center of the cartridge insertion / removal port 10a. Specifically, the angle θ at which the spindle O intersects the diagonal line O1 connecting the first corner portion 12C1 (input device 15) and the third corner portion 12C3 is less than 90 °. According to this configuration, it becomes easy for the user to put a finger on the input device 15 while holding the suction port portion 11 attached to the cartridge insertion / removal port 10a.

The main body unit 2 is provided with a movement restricting member (cover member 17, sensor holder 35) that restricts the movement of the cartridge accommodating portion 10 as a measure for pulling out the cartridge accommodating portion 10 that partially protrudes from the outer case 12. The movement restricting member restricts the movement of the cartridge accommodating portion 10 in the extraction direction, which is at least extracted from the outer case 12. Here, the "pull-out direction" means one direction toward the upper side (+ Z side) of the main axis direction (Z-axis direction).

As shown in FIG. 6, the outer case 12 has a main body case 13 in which the opening 13a is formed. The cover member 17 (movement limiting member) has a main body case side protrusion 17A inserted into the opening 13a. The main body case side protrusion 17A is locked to the outer case 12 at least in the extraction direction, and restricts the movement of the cartridge accommodating portion 10.

Further, the cover member 17 has a cartridge accommodating portion side protrusion 17C inserted into the through hole 10c of the cartridge accommodating portion 10. The cartridge accommodating portion side protrusion 17C is caught by the cartridge accommodating portion 10 even if the cover member 17 is peeled off from the peripheral surface of the cartridge accommodating portion 10 by pulling out the cartridge accommodating portion 10, and the cartridge accommodating from the outer case 12. Prevents the part 10 from being pulled out.

Further, the cover member 17 has a plate portion 17B interposed between the cartridge accommodating portion 10 and the outer case 12. The thickness of the plate portion 17B decreases toward the extraction direction of the cartridge accommodating portion 10 (see FIG. 28). The plate portion 17B has a wedge space between the cartridge accommodating portion 10 and the outer case 12 (specifically, the rounded inner wall surface of the second corner portion 12C2 of the outer case 12 gradually forms a peripheral surface of the cartridge accommodating portion 10. Is inserted into the space close to). That is, the plate portion 17B becomes a wedge to prevent the cartridge accommodating portion 10 from being pulled out from the outer case 12.

As shown in FIG. 29, a second notch 42d2 is formed in the second rib 42D in the holder 30 fixed to the outer case 12. The sensor holder 35 (movement limiting member) has a holder-side protrusion 35B inserted into the second notch 42d2. The holder-side protrusion 35B is locked to the holder 30 at least in the extraction direction to limit the movement of the cartridge accommodating portion 10.

Further, the sensor holder 35 has a cartridge accommodating portion side protrusion 35D inserted into the through hole 10d of the cartridge accommodating portion 10. The cartridge accommodating portion side protrusion 35D is caught by the cartridge accommodating portion 10 even if the sensor holder 35 is peeled off from the peripheral surface of the cartridge accommodating portion 10 by pulling out the cartridge accommodating portion 10, and the cartridge accommodating from the outer case 12. Prevents the part 10 from being pulled out.

<Assembly method of suction device>
FIG. 37 is an explanatory diagram showing a state in which the cartridge 3 is accommodated in the cartridge accommodating portion 10 according to the embodiment. FIG. 38 is an explanatory diagram showing how the mouthpiece 11 is attached to the cartridge accommodating portion 10 according to the embodiment.
As shown in FIG. 37, when assembling the aspirator 1, the cartridge 3 is accommodated in the cartridge accommodating portion 10 of the main body unit 2. As shown in FIG. 5, the cartridge 3 is inserted from the cartridge insertion / removal port 10a of the cartridge accommodating portion 10 protruding from the outer case 12 with the flat electrode 26h facing the main body unit 2.

Since the cartridge 3 is shorter than the cartridge accommodating portion 10, it freely falls when inserted. At this time, since there is nothing around the cartridge 3 that hinders the movement of the cartridge 3 in the rotational direction, and the cartridge 3 is also falling with a certain force, the engaging protrusion 43h of the positioning mechanism 90 and the engaging protrusion 43h. Even if the circumferential position of the cartridge 3 does not match the engagement groove portion 26i, the cartridge 3 bounces and rotates due to the collision with the engagement protrusion 43h, or the curved surface of the engagement protrusion 43h. As the cartridge 3 slides down along the cartridge 3, the engaging protrusion 43h enters the engaging groove 26i.

Here, in the present embodiment, the gap generated between the inner diameter D1 of the cartridge accommodating portion 10 and the outer diameter D2 of the cartridge 3 is larger than 2.6% of the inner diameter of the cartridge accommodating portion 10. Therefore, the clearance between the cartridge accommodating portion 10 and the cartridge 3 is large, and the engaging protrusion 43h can be easily attracted to the engaging groove portion 26i. That is, when the cartridge 3 is inserted, the cartridge 3 is assembled in the regular position even if the circumferential positions of the engaging protrusion 43h and the engaging groove 26i do not match. As a result, the flat electrode 26h of the cartridge 3 comes into contact with the protruding electrode 50.

Note that the cartridge 3 may not be assembled in the proper position when the cartridge 3 is inserted as described above. In this case, the cartridge 3 is in a state of riding on the engaging protrusion 43h (hereinafter, simply referred to as a “riding state”). In the mounted state of the cartridge 3, the movement of the cartridge 3 on the lower side (−Z side) in the main axis direction is restricted. Therefore, the flat electrode 26h and the protruding electrode 50 are separated from each other in the main axis direction, and the conduction between the cartridge 3 and the main body unit 2 is not ensured.

If the mouthpiece 11 is attached to the cartridge accommodating portion 10 while the cartridge 3 is in the mounted state, the cartridge contact portion 60 comes into contact with the cartridge 3 before the attachment of the mouthpiece 11 is completed. Specifically, the cartridge contact portion 60 comes into contact with the cartridge 3 while the protrusion 11b1 of the mouthpiece portion 11 passes through the first groove portion 10b1 or the second groove portion 10b2 of the mouthpiece connection portion 10B. Then, the cartridge contact portion 60 is compressed in the main axis direction, and the cartridge 3 is pressed against the engaging protrusion 43h. Since the engaging protrusion 43h has a curved surface shape, even if the center of the engaging protrusion 43h and the center of the engaging groove 26i do not match in the circumferential direction, the engaging protrusion 43h is engaged with the tip of the engaging protrusion 43h. When the groove portion 26i is engaged, the cartridge 3 slides down diagonally along the curved surface of the engaging protrusion 43h, and the cartridge 3 is assembled in the proper position.

Further, if the cartridge 3 is still in the riding state even when the cartridge 3 is pressed, as shown in FIG. 38, the mouthpiece 11 is rotated with the cartridge contact portion 60 in contact with the cartridge 3. .. Then, the cartridge 3 rotates together while the protrusion 11b1 passes through the third groove portion 10b3 of the mouthpiece connecting portion 10B. The cartridge 3 rotates due to the frictional force generated between the cartridge 3 and the cartridge contact portion 60. When the tip (apex) of the engaging protrusion 43h faces the engaging groove portion 26i due to the rotation of the cartridge 3, the cartridge 3 slides down along the curved surface of the engaging protrusion 43h, and the engaging protrusion 43h becomes the engaging groove portion. Enter within 26i. As described above, in the present embodiment, the cartridge 3 can be assembled in the proper position in three stages of free fall of the cartridge 3, pressing of the cartridge 3, and rotation of the cartridge 3.

When the mouthpiece 11 is rotated to the end and the mouthpiece 11 is attached to the cartridge accommodating portion 10, the cartridge contact portion 60 is in a compressed state in the main axis direction, the flat electrode 26h is pressed against the protruding electrode 50, and the cartridge is pressed. 3 is positioned. In this way, by mounting the suction port portion 11, the cartridge 3 is positioned, and the cartridge 3 and the main body unit 2 are electrically connected to each other. In addition, the annular projection 61 of the cartridge contact portion 60 is compressed in the main axis direction, so that the gap between the cartridge 3 and the mouthpiece portion 11 is sealed.
With the above, the assembly of the suction device 1 is completed. As shown in FIGS. 37 and 38, the flavor source container 4 may be inserted into the mouthpiece 11 in advance, but if this is not the case, the mouthpiece 11 is attached to the cartridge accommodating part 10 and then the mouthpiece 11. By inserting the flavor source container 4 into the container, the assembly of the suction cup 1 is completed.

<How to use the aspirator>
When using the aspirator 1 described above, the user first presses the input device 15 shown in FIG. At this time, for example, the main unit 2 may be programmed to start by pressing the input device 15 a plurality of times.

Subsequently, the user sucks the mouthpiece 11 or the flavor source container 4 while holding the mouthpiece 11. Then, the air inside the cartridge accommodating portion 10 flows, and the sensor 34 shown in FIG. 29 detects the puff. When the sensor 34 detects the puff, the heating wire 25b of the cartridge 3 shown in FIG. 6 is energized, and the heating wire 25b generates heat. When the heating wire 25b generates heat, the aerosol source of the liquid impregnated in the wick 25a is heated and atomized. The atomized aerosol is sucked up together with the air (outside air) taken in by suction.

As shown in FIG. 29, air (outside air) is taken in from the air inlet 18 in the gap between the main body case 13 and the cover member 17. The air taken in from the air inlet 18 flows into the inside of the cartridge accommodating portion 10 through the annular groove portion 71, the step groove portion 72, the air hole 19, and the air communication hole 10e of the air groove 70. As shown in FIG. 6, the air flowing into the cartridge accommodating portion 10 flows into the atomization chamber 24c through the intake hole 26c and the opening 24e of the cartridge 3.

The atomized aerosol fills the atomization chamber 24c, and together with the air flowing into the atomization chamber 24c, the suction port is passed through the flow path pipe 21c, the through hole 21b, and the communication hole 62 of the cartridge contact portion 60. It is sucked up to the part 11 side. After that, the atomized aerosol and the mixed gas of air enter the user's mouth through the flavor source container 4 attached to the mouthpiece 11. This allows the user to taste the flavor.
