More specifically, the fitting portion 11 of the present embodiment is configured to be fitted into the concha CA so as to come into contact with the inner surface of the concha cavity among the inner surfaces of the concha CA. By heating the inner surface of the concha CA, particularly the inner surface of the concha cavity, by the thermal body 2 through the fitting portion 11, the internal parasympathetic nerve can be efficiently heated. Thereby, the above-mentioned relaxing effect can be further enhanced.

Hereinafter, for convenience of explanation, the extending direction of the fitting portion 11 is described as "height direction A of the fitting portion 11" or simply "height direction A". The fitting portion 11 of the present embodiment has a substantially truncated cone-shaped outer shape. Therefore, the height direction A of the fitting portion 11 of the present embodiment is the central axis direction of the annular side wall portion 15 (see FIG. 1 and the like) described later. Further, hereinafter, for convenience of explanation, the direction from the base end side to the tip end side of the fitting portion 11 in the height direction A of the fitting portion 11 may be simply referred to as "upper side". Further, in the height direction A of the fitting portion 11, the direction from the tip end side to the base end side of the fitting portion 11 may be simply described as "lower side". The upper side of the present embodiment means one end side of the annular side wall portion 15 (see FIG. 1 and the like) to which the top plate portion 16 (see FIG. 1 and the like) to be described later is connected. The lower side of the present embodiment means the other end side of the annular side wall portion 15 opposite to the one end side on which the top plate portions 16 are connected.

As shown in FIGS. 5 to 8, the fitting portion 11 of the present embodiment internally partitions a storage space 15a capable of accommodating a heating body 2 that heats the inner surface of the concha CA through the fitting portion 11. .. The fitting portion 11 of the present embodiment includes a convex surface that contacts the inner surface of the concha CA and a concave surface that partitions the accommodation space 15a on the back side of the convex surface. Specifically, the fitting portion 11 of the present embodiment includes an annular side wall portion 15 and a top plate portion 16. The annular side wall portion 15 is configured to be fitable to the concha CA. In particular, the annular side wall portion 15 of the present embodiment can be fitted so as to be sandwiched between the inner side surfaces of the concha CA. More specifically, the annular side wall portion 15 of the present embodiment can be fitted so as to be sandwiched between the inner surface of the concha cavity of the inner surface of the concha CA. The annular side wall portion 15 internally partitions a storage space 15a that can accommodate the main body portion 2a (see FIG. 4) of the thermal body 2. The top plate portion 16 is connected to one upper end (hereinafter, referred to as “upper end”) of the annular side wall portion 15. The upper end of the accommodation space 15a of the annular side wall portion 15 is closed by the top plate portion 16. In other words, the accommodation space 15a of the present embodiment is a truncated cone-shaped space partitioned by the annular side wall portion 15 and the top plate portion 16. The top plate portion 16 has a contact surface 16a that can come into contact with the bottom surface of the concha CA in a state where the annular side wall portion 15 is fitted to the concha CA. More specifically, the contact surface 16a of the present embodiment is configured to be able to contact the bottom surface of the concha cavity among the bottom surfaces of the concha CA. The contact surface 16a of the top plate portion 16 of the present embodiment is composed of a top plate upper surface 17a opposite to the top plate lower surface 17b facing the accommodation space 15a in the top plate portion 16.

The above-mentioned thermal body 2 is attached to the ear fitting 4 by accommodating the main body portion 2a in the accommodating space 15a. Specifically, the main body portion 2a of the thermal body 2 is an open end that is a lower end (hereinafter, referred to as “lower end”) on the side opposite to the upper end that is connected to the top plate portion 16 of the annular side wall portion 15. Therefore, it can be accommodated in the accommodation space 15a.

The outer shape of the fitting portion 11 of the present embodiment is a truncated cone shape, but the outer shape is not particularly limited. The outer shape of the fitting portion 11 may be, for example, a cylindrical shape. Further, the outer shape of the fitting portion 11 may be, for example, a shape corresponding to the inner surface of the instep CA. Therefore, the annular side wall portion 15 in the fitting portion 11 is not limited to the tapered tubular shape of the present embodiment. The annular side wall portion 15 may have a cylindrical shape having a uniform inner diameter and outer diameter regardless of the position in the central axial direction. However, the outer surface of the annular side wall portion 15 has a tapered shape that tapers from the lower end on the side opposite to the upper end where the top plate portions 16 are connected toward the upper end where the top plate portions 16 are connected, as in the present embodiment. Is preferable. By doing so, it becomes easy to fit the fitting portion 11 into the instep CA. Further, the annular side wall portion 15 does not have to have a circular outer shape in a cross section orthogonal to the height direction A, and the outer cross section may have an endless shape corresponding to the inner surface of the concha CA. Further, the top plate portion 16 of the present embodiment is configured by a circular flat flat plate portion that closes the upper end of the tapered tubular annular side wall portion 15, but is not limited to this configuration. The top plate portion 16 is preferably configured so that the area where the contact surface 16a contacts the bottom surface of the concha CA can be increased. Therefore, the top plate portion 16 may be configured by, for example, a curved plate portion curved in a dome shape so that the contact surface 16a is a convex surface. Further, the accommodation space 15a of the present embodiment is a space having a substantially truncated cone shape, but the shape of the accommodation space 15a is not particularly limited. The accommodation space 15a of the present embodiment may be configured so that at least a part of the heating body 2 can be accommodated and the auricle AU can be heated through the fitting portion 11. In the present embodiment, the main body portion 2a of the thermal body 2 is accommodated in the accommodation space 15a, so that the main body portion 2a is covered with the annular side wall portion 15 and the top plate portion 16.

<Insert part 12>

As shown in FIGS. 5 and 6, the insertion portion 12 protrudes from the fitting portion 11. The insertion portion 12 is configured to be insertable into the external ear canal EA (see FIG. 3) together with the cover member 3 to be attached. Specifically, the insertion portion 12 of the present embodiment faces outward from the fitting portion 11 in a plan view (see FIGS. 5A and 5B) seen in the height direction A of the fitting portion 11. Is protruding. More specifically, the insertion portion 12 of the present embodiment projects from the annular side wall portion 15 of the fitting portion 11 to the outside of the annular side wall portion 15 in the radial direction B. Hereinafter, for convenience of explanation, the radial direction B of the annular side wall portion 15 may be simply referred to as “diameter direction B”.

The insertion portion 12 of the present embodiment has a base end portion 12a connected to the annular side wall portion 15 and a tip end portion 12b connected to the base end portion 12a and inserted into the mounting cylinder portion 3a (see FIG. 9) of the cover member 3. And. The tip portion 12b has a substantially columnar outer shape. The central axial direction C, which is the extending direction of the tip portion 12b, is inclined with respect to the height direction A of the fitting portion 11. The tip portion 12b can be inserted into the mounting cylinder portion 3a of the cover member 3 so as to push the mounting cylinder portion 3a outward in the radial direction. As a result, the outer surface of the tip portion 12b is in close contact with the inner surface of the mounting cylinder portion 3a. As a result, the cover member 3 is held by the insertion portion 12 of the ear wearer 4. Further, in addition to the close contact between the outer cylinder portion 3b and the inner surface of the outer ear hole EA, the outer surface of the tip portion 12b and the inner surface of the mounting cylinder portion 3a can further close the outer ear hole EA, and the sound insulation by the heating tool 100 can be achieved. Can be further enhanced.

Further, the tip portion 12b of the present embodiment includes an annular convex portion 12b1 protruding outward in the radial direction. When the tip portion 12b of the insertion portion 12 is inserted into the mounting cylinder portion 3a of the cover member 3, the annular convex portion 12b1 of the tip portion 12b is provided with the annular recess 3a1 on the inner surface of the mounting cylinder portion 3a (see FIG. 9). ). This makes it difficult for the mounting cylinder portion 3a to come off from the tip portion 12b. Therefore, the holdability of the cover member 3 by the insertion portion 12 can be improved.

The insertion portion 12 of the present embodiment is formed separately from the cover member 3 so that the cover member 3 described above can be attached, but may be integrally formed. Therefore, the tip portion 12b of the insertion portion 12 of the present embodiment may be formed so as to be integrally connected with the mounting cylinder portion 3a of the cover member 3, for example.

Further, the ear fitting 4 of the present embodiment includes an insertion portion 12, but is not limited to this configuration. The ear fitting 4 of the present embodiment is configured to be fixed to the ear by being in close contact with the inner surface of the external ear canal EA. For example, if the ear fitting 4 is fixed only to the auricle AU, the ear is fixed. The fitting 4 does not have to include the insertion portion 12. However, from the viewpoint of the relaxing effect due to the sound insulation, the heating device 100 preferably includes an insertion portion 12 that can be inserted into the external ear canal EA. Further, it is preferable that the heating tool 100 further includes a cover member 3 attached to the insertion portion 12 in order to enhance the adhesion of the external ear hole EA to the inner surface. By doing so, the relaxing effect due to the sound insulation can be further enhanced. Although the insertion portion 12 of the present embodiment is integrally formed with the fitting portion 11, it may be formed separately from the fitting portion 11 and detachably attached to the fitting portion 11.

<Holding unit 13>

The holding portion 13 can hold the thermal body 2 that heats the inner surface of the auricle CA of the auricle AU through the fitting portion 11.

In particular, in the ear fitting 4 of the present embodiment, a collar that protrudes outward in the radial direction B from the opening end that is the lower end of the fitting portion 11 and connects the fitting portion 11 and the second regulating wall portion 19b of the holding portion 13. A connecting flange portion 20 is provided as a portion. Then, in the present embodiment, the connecting flange portion 20, together with the lower end of the fitting portion 11, restricts the movement of the held portion 2b of the thermal body 2 on the upper side in the height direction A. However, the ear fitting 4 may have a portion connecting the fitting portion 11 and the holding portion 13, and the configuration thereof is not limited to the connecting flange portion 20 of the present embodiment. Therefore, the movement of the held portion 2b of the thermal body 2 on the upper side in the height direction A may be restricted by the lower end of the fitting portion 11 described above, and the regulation by the connecting flange portion 20 is not essential.

In the ear fitting 4 of the present embodiment, the fitting portion 11 is connected to the second regulation wall portion 19b via the connecting flange portion 20. A support protrusion 18b projects from the second regulation wall portion 19b to the inside in the radial direction B. Further, the second regulation wall portion 19b is connected to the support plate portion 18a. The first regulation wall portion 19a is connected to the outer edge of the support plate portion 18a. As described above, in the ear fitting 4 of the present embodiment, the fitting portion 11 and the holding portion 13 are connected to each other via the connecting flange portion 20. In the present embodiment, the fitting portion 11 and the holding portion 13 are integrally formed via the connecting flange portion 20, but at least one of the fitting portion 11, the holding portion 13 and the connecting flange portion 20 is formed as a separate body. , May be joined by adhesion, welding or the like.

As shown in FIG. 6, the support plate portion 18a of the present embodiment faces the lower surface of the base end portion 12a of the above-mentioned insertion portion 12 with a gap in the height direction A. Between the lower surface of the base end portion 12a of the insertion portion 12 and the upper surface of the support plate portion 18a, the held portion 2b of the thermal body 2 can be inserted from the inside to the outside in the radial direction B. As shown in FIG. 6, the first regulation wall portion 19a extends upward from the outer edge portion outside the radial direction B of the support plate portion 18a and is connected to the base end portion 12a of the insertion portion 12.

<Connecting collar 20>

As described above, the ear fitting 4 of the present embodiment includes a connecting collar portion 20 as a flange portion in addition to the fitting portion 11, the insertion portion 12, and the holding portion 13. The connecting flange portion 20 of the present embodiment is connected to the fitting portion 11. More specifically, the connecting flange portion 20 of the present embodiment projects outward from the lower end of the fitting portion 11 in the radial direction B, and connects the fitting portion 11 and the second regulating wall portion 19b of the holding portion 13. As shown in FIG. 5A and the like, the outer edge of the connecting flange portion 20 is the second regulating wall portion 19b of the regulating wall portion 19 that covers the periphery of the held portion 2b of the thermal body 2 in the housed state (FIG. 5). In addition to the wall connecting end portion 20b connected to (b)), a free end portion 20a not connected to the second regulated wall portion 19b of the regulated wall portion 19 is provided. Further, the length L1 in the radial direction B of the connecting flange portion 20 at the position of the free end portion 20a is shorter than the length L2 in the radial direction B of the connecting flange portion 20 at the position of the wall connecting end portion 20b. As shown in FIGS. 5B, 6 and 7, a ventilation groove 21 extending from the position of the free end portion 20a to the accommodation space 15a is formed on the lower surface of the connecting flange portion 20. Therefore, in the present embodiment, the ventilation groove 21 connects the ventilation path 30 from the position of the free end portion 20a of the connecting flange portion 20 to the recess provided at the opening end which is the lower end of the fitting portion 11 and communicates with the accommodation space 15a. It is partitioned. Therefore, in a state where the main body 2a of the heat body 2 is housed in the storage space 15a, the held portion 2b of the heat body 2 is in contact with the opening end of the fitting portion 11 and the lower surface of the connecting flange portion 20. However, air can be taken into the accommodation space 15a through the ventilation groove 21. Therefore, even when the main body portion 2a including the heat generating composition 5 (see FIG. 4) that generates heat when it comes into contact with air is accommodated in the accommodation space 15a, the air is taken into the accommodation space 15a through the ventilation groove 21. , Can be heated. In the ear fitting 4 of the present embodiment, the ventilation passage 30 is partitioned by the ventilation groove 21, but the ventilation passage 30 is not limited to the configuration of the present embodiment (see FIGS. 11 and 12). The details of the ventilation path 30 of this embodiment will be described later.

Further, as shown in FIG. 2, in the present embodiment, in a state where the thermal body 2 is attached to the ear fitting 4, a part of the held portion 2b of the thermal body 2 is radially B from the free end portion 20a. Exposed to the outside. Therefore, when the thermal body 2 is removed from the ear wearing tool 4, the portion of the held portion 2b of the thermal body 2 exposed from the free end portion 20a may be grasped and operated. By doing so, the thermal body 2 can be easily removed from the ear fitting 4.

Further, as shown in FIG. 5A, the connecting flange portion 20 of the present embodiment is in the circumferential direction D of the fitting portion 11 (in the present embodiment, the same direction as the circumferential direction of the annular side wall portion 15, and hereinafter, simply In the "circumferential direction D"), it is not provided at the positions on both sides of the insertion portion 12. Therefore, the ear fitting 4 of the present embodiment is configured so that the upper surface of the support plate portion 18a can be visually recognized in the top view shown in FIG. 5A. In the thermal body 2 of the present embodiment, the held portion 2b is inserted between the lower surface of the base end portion 12a of the insertion portion 12 and the upper surface of the support plate portion 18a from the inside to the outside in the radial direction B. , Attached to the ear wearer 4. Therefore, since the connecting flange portions 20 are not provided on both sides of the insertion portion 12 in the circumferential direction D, the held portion 2b of the thermal body 2 is the lower surface of the base end portion 12a of the insertion portion 12 and the support plate portion 18a. Whether or not it is properly inserted between it and the upper surface can be visually recognized from the outside.

The ear fitting 4 of the present embodiment includes a connecting flange portion 20 protruding outward in the radial direction B from the opening end which is the lower end of the fitting portion 11 in order to connect the fitting portion 11 and the holding portion 13. As long as the fitting portion 11 and the holding portion 13 are connected to each other, the configuration is not limited to the configuration of the connecting flange portion 20 of the present embodiment. However, as in the present embodiment, it is preferable to use the connecting flange portion 20 having a lower surface in which the lower end of the fitting portion 11 and the position in the height direction A are equal to each other. By doing so, the flange-shaped held portion 2b of the thermal body 2 moves so as to be tilted with respect to the height direction A in the accommodation state in which the main body portion 2a of the thermal body 2 is accommodated in the accommodation space 15a. Can be suppressed. As a result, the main body 2a of the thermal body 2 does not easily come off from the accommodation space 15a. Therefore, the positional stability of the thermal body 2 in the state where the held portion 2b of the thermal body 2 is held by the holding portion 13 can be further improved.

The material constituting the ear fitting 4 is not particularly limited, and examples thereof include synthetic resins including rubber, elastomers, soft resins, and hard resins. More specifically, polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), elastomer and the like can be mentioned. The material constituting the ear fitting 4 may be a material having high thermal conductivity in terms of efficiently transferring the heat of the thermal body 2 to the pinna AU (see FIG. 3). Examples of such a material include those in which a material having a high thermal conductivity such as metal and carbon is mixed with a base material such as rubber, an elastomer, and a synthetic resin to increase the thermal conductivity. Further, a heat conductive resin having a high thermal conductivity may be used.

[Ventilation channel 30]

Next, the ventilation passage 30 that communicates the outside with the accommodation space 15a in a state where the thermal body 2 is accommodated in the accommodation space 15a will be described. FIG. 9 is a cross-sectional view of the heating tool 100 in a used state in which the heating body 2 and the cover member 3 are attached to the ear wearing tool 4. FIG. 9 shows a cross section at the same position as the position of line II in FIG. 5 in a state where the heating body 2 and the cover member 3 are attached to the ear fitting 4. Further, FIG. 10 is a cross-sectional view taken at the same position as FIG. 9, showing a state in which the thermal body 2 is being attached to the ear wearing tool 4.

First, the details of the holding state of the thermal body 2 by the ear fitting 4 shown in FIG. 9 will be described. As shown in FIG. 9, the holding portion 13 of the present embodiment can hold the heating body 2 that heats the inner surface of the auricle CA (see FIG. 3) of the auricle AU (see FIG. 3) through the fitting portion 11. Is. In the present embodiment, as described above, the support portion 18 and the regulation wall portion 19 of the holding portion 13 are the held portions of the heating body 2 in the accommodation state in which the main body portion 2a of the heating body 2 is accommodated in the accommodation space 15a. Hold 2b.

Here, the holding portion 13 limits the movement of the heat body 2 with respect to the ear wearer 4 within a predetermined range so that the heat body 2 does not separate from the ear wearer 4. That is, the configuration of the holding portion 13 is not limited to the configuration in which the heating body 2 is held so as not to move with respect to the ear fitting 4.

As shown in FIG. 9, the holding portion 13 of the present embodiment holds the held portion 2b of the thermal body 2 so as to be movable within a predetermined range in the height direction A. Specifically, in the holding portion 13 of the present embodiment, the upper surface of the held portion 2b is fitted into the holding portion 11 from a position where the lower surface of the held portion 2b is in contact with and supported by the support plate portion 18a and the support protrusion portion 18b. The thermal body 2 is held so that the thermal body 2 can move in the height direction A within the range up to the position where it contacts the lower end of the joint portion 20 and the lower surface of the connecting flange portion 20. In FIG. 9, the uppermost holding position of the heating body 2 is such that the upper surface of the held portion 2b of the heating body 2 is in contact with the opening end which is the lower end of the fitting portion 11 and the lower surface of the connecting flange portion 20. Shows.

Further, as shown in FIG. 9, the holding portion 13 of the present embodiment holds the held portion 2b of the thermal body 2 in a state of being immovable in a direction orthogonal to the height direction A. Specifically, in the present embodiment, the first regulation wall portion 19a and the second regulation wall portion 19b of the regulation wall portion 19 are around the held portion 2b of the heating body 2 in the direction orthogonal to the height direction A. Is located. Therefore, the first regulation wall portion 19a and the second regulation wall portion 19b of the regulation wall portion 19 come into contact with the outer edge of the held portion 2b of the heat body 2, so that the heat body is orthogonal to the height direction A. The movement of 2 is regulated. However, as described above, the holding portion 13 may hold the held portion 2b of the thermal body 2 so as to be movable within a predetermined range in the direction orthogonal to the height direction A.

Here, as shown in FIG. 9, the holding portion 13 may hold the thermal body 2 in a state where the holding portion 13 is separated from the fitting portion 11 by a gap X. When the holding portion 13 movably holds the thermal body 2 within a predetermined range as in the present embodiment, the thermal body 2 at an arbitrary position within the movable predetermined range is fitted. The space X may be separated from the portion 11 so as to be separated from the portion 11. FIG. 9 shows a state in which the heating body 2 is in the uppermost holding position. Even in this state, the main body portion 2a of the heating body 2 of the present embodiment is the annular side wall portion 15 of the fitting portion 11 and the ceiling. The state of being separated from the plate portion 16 by the gap X is maintained. By doing so, it is possible to suppress a rapid temperature rise of the fitting portion 11 due to the thermal body 2 and to prevent burns from occurring on the inner surface of the auricle CA of the auricle AU to which the fitting portion 11 comes into contact.

Further, the holding portion 13 of the present embodiment is housed inside the annular side wall portion 15 from the top plate lower surface 17b side, which is the back surface side of the top plate upper surface 17a, which is the contact surface 16a of the top plate portion 16. In the state, the thermal body 2 is held. The holding portion 13 is configured to hold the heating body 2 housed in the housing space 15a in the annular side wall portion 15 as described above, so that the heating body 2 can be easily attached to the ear fitting 4. Can be done.

More specifically, as shown in FIG. 9, in the holding portion 13 of the present embodiment, the main body portion 2a of the thermal body 2 is housed inside the annular side wall portion 15 from the top plate lower surface 17b side of the top plate portion 16. In this state, the held portion 2b protruding from the main body portion 2a of the thermal body 2 is held. By doing so, as described above, the thermal body 2 can be easily attached to the ear fitting 4. Further, the held portion 2b of the thermal body 2 comes into contact with the lower end of the annular side wall portion 15 which is the lower end of the fitting portion 11, so that the amount of pushing of the main body portion 2a into the annular side wall portion 15 can be regulated. .. As a result, a gap X can be easily secured between the main body portion 2a of the thermal body 2 and the top plate portion 16.

As shown in FIG. 10, in the heating tool 100 of the present embodiment, the flange portion as the held portion 2b of the heating body 2 is placed in the gap between the support plate portion 18a and the insertion portion 12 in the radial direction B. The main body portion 2a of the thermal body 2 is accommodated in the accommodation space 15a inside the annular side wall portion 15 from the lower end side of the annular side wall portion 15 while being inserted from the inside to the outside. The main body portion 2a is housed in the annular side wall portion 15, except for the portion of the held portion 2b of the thermal body 2 that is inserted into the gap between the support plate portion 18a and the insertion portion 12, the support protrusion portion 18b. That is, it is completed when the held portion 2b is held by the holding portion 13.

Further, as shown in FIG. 9, the holding portion 13 of the present embodiment holds the heating body 2 in a state where the main body portion 2a of the heating body 2 is covered with the fitting portion 11. In this way, the fitting portion 11 covers the main body portion 2a of the heating body 2, so that the heat generated in the main body portion 2a is not consumed due to the heating of the fitting portion 11 and is wasted. Can be suppressed.

It is preferable that the fitting portion 11 covers at least the surface of the heating portion of the heating body 2 that heats the fitting portion 11. Therefore, like the fitting portion 11 of the present embodiment, the surface of the main body portion 2a as the heating portion for heating the fitting portion 11 of the heating body 2 is covered, and the held portion 2b which is not the heating portion is covered. It may be a configuration that does not cover.

Next, the ventilation groove 21 for partitioning the ventilation passage 30 will be described. In the ear fitting 4, the ventilation passage 30 that communicates the outside and the accommodation space 15a is defined in a state where the thermal body 2 is accommodated in the accommodation space 15a. The ventilation passage 30 of the present embodiment is partitioned by the ventilation groove 21 described above, but is not limited to this configuration. The details will be described later (see FIG. 11 and the like). The ear fitting 4 is provided with a ventilation passage 30 capable of supplying air to the accommodation space 15a of the fitting portion 11, so that the thermal body 2 needs to supply air into the accommodation space 15a due to heat generation. Even if it exists, it can be used by attaching it to the ear fitting 4. Therefore, regardless of the type of the heating body 2, the instep CA can be efficiently heated by the heating body 2.

The thermal body 2 of the present embodiment has a configuration in which air needs to be supplied into the accommodation space 15a in order to generate heat. Specifically, the main body 2a of the thermal body 2 of the present embodiment can generate heat in the heat generating composition 5 inside by allowing air to enter from the surface of the first sheet 6a having air permeability. Therefore, when the surface of the main body portion 2a on the first sheet 6a side is accommodated in the accommodation space 15a in the fitting portion 11 as in the present embodiment, it is necessary to supply air into the accommodation space 15a from the outside. be. As described above, in the heating tool 100 of the present embodiment, the flange-shaped held portion 2b of the heating body 2 is in a state where it can contact the lower end of the fitting portion 11 of the ear fitting 4 and the lower surface of the connecting flange portion 20. , Is held by the holding portion 13. Therefore, when the entire circumferential direction of the opening end, which is the lower end of the fitting portion 11, comes into contact with the flange-shaped held portion 2b of the heating body 2, air cannot be taken into the accommodation space 15a from the opening end of the fitting portion 11. ..

Therefore, the ventilation passage 30 of the present embodiment is connected to the opening end of the fitting portion 11 facing the held portion 2b of the thermal body 2 in the accommodation state in which the main body portion 2a of the thermal body 2 is accommodated in the accommodation space 15a. It is partitioned by a ventilation groove 21 extending over the lower surface, which is the facing surface of the flange portion 20. By doing so, as shown in FIG. 9, the flange-shaped held portion 2b of the thermal body 2 is in contact with the lower end of the fitting portion 11 of the ear fitting 4 and the lower surface of the connecting flange portion 20. However, the ventilation passage 30 defined by the ventilation groove 21 is not blocked. Therefore, air can be taken into the accommodation space 15a from the outside through the ventilation passage 30.

The ventilation passage 30 of the present embodiment is partitioned by the ventilation groove 21 across both the fitting portion 11 and the connecting flange portion 20, but is not limited to this configuration. FIG. 11 is a diagram showing a modified example of the ventilation path 30. As shown in FIG. 11A, the ventilation passage 30 may be partitioned by, for example, a notch 22 formed so as to straddle the fitting portion 11 and the connecting flange portion 20. Further, the ventilation passage 30 may be partitioned by, for example, a ventilation hole extending through the fitting portion 11 and the connecting flange portion 20. Further, as shown in FIG. 11B, the ventilation passage 30 may be partitioned only by, for example, the fitting portion 11. As shown in FIG. 11B, the ventilation passage 30 partitioned only by the fitting portion 11 may be partitioned by, for example, a ventilation hole 23 penetrating the annular side wall portion 15 of the fitting portion 11 in the radial direction B. .. As described above, the shape of the ventilation path 30 is not particularly limited. Further, the size and number of the ventilation holes may be appropriately determined according to the required ventilation amount, and is not particularly limited.

Further, as shown in FIGS. 5 (b), 9 and the like, the ventilation groove 21 of the present embodiment is connected to the outside by a free end portion 20a at the outer edge of the connecting flange portion 20 from the inner end connected to the accommodation space 15a. It extends to the edge. By doing so, the outer end of the ventilation groove 21 is not covered by the second regulation wall portion 19b of the regulation wall portion 19. Therefore, it becomes easy to secure ventilation through the ventilation passage 30 defined by the ventilation groove 21. Further, as shown in FIG. 5A, the length L1 in the radial direction B of the connecting flange portion 20 at the position of the free end portion 20a is the radial direction of the connecting flange portion 20 at the position of the wall connecting end portion 20b. It is shorter than the length L2 in B. Therefore, the length of the ventilation passage 30 partitioned by the ventilation groove 21 can be shortened, and it becomes easier to secure ventilation between the outside and the accommodation space 15a through the ventilation passage 30.

Further, as shown in FIG. 5B, the ventilation passage 30 of the present embodiment is provided at a position different from the position where the insertion portion 12 is provided in the circumferential direction D. Therefore, even when the heating tool 100 is attached to the ear, the outer end of the ventilation groove 21 is easily exposed to the outside, and it is easy to secure ventilation through the ventilation path 30 defined by the ventilation groove 21.

More specifically, as shown in FIG. 5B, the ventilation passage 30 of the present embodiment is provided at a position including the second position P2 in the circumferential direction D. Here, in the circumferential direction D, the position where the insertion portion 12 protrudes outward from the fitting portion 11 is defined as the “first position P1”, and is viewed in a plan view along the height direction A of the fitting portion 11 (FIG. 5). In (a) and FIG. 5 (b), the position on the opposite side of the first position P1 and the fitting portion 11 is referred to as the "second position P2". The first position P1 means the midpoint in the circumferential direction D of the insertion portion 12 in the plan view (see FIGS. 5A and 5B).

However, the position of the ventilation path 30 is not limited to the position of the present embodiment. The ventilation passage 30 may be provided between the first position P1 and the second position P2 in the circumferential direction D. By providing the ventilation passage 30 between the first position P1 and the second position P2 in the circumferential direction D, it becomes easy to attach the heating tool 100 to the ear with the ventilation passage 30 facing upward in the vertical direction. .. Therefore, the end portion of the ventilation passage 30 is easily exposed to the outside, and it is easy to secure ventilation, and the ventilation passage 30 is directed upward in the vertical direction, so that the ventilation passage 30 can be prevented from being clogged with water vapor.

The ear-wearing device and the heating device according to the present invention are not limited to the specific configurations shown in the above-described embodiment, and can be variously modified and modified as long as they do not deviate from the scope of claims. The ear fitting 4 of the above-described embodiment includes the connecting collar portion 20 as a flange portion, but may be configured not to include the connecting collar portion 20. In such a case, as shown in FIG. 12, the ventilation passage 30 may be partitioned by, for example, a fitting portion 11. FIG. 12 is a diagram showing an example of a ventilation path 30 partitioned by the annular side wall portion 15 of the fitting portion 11. As shown in FIG. 12A, the ventilation passage 30 may be partitioned by a ventilation groove 24 formed at the open end of the annular side wall portion 15. Further, as shown in FIG. 12B, the ventilation passage 30 may be partitioned by a ventilation hole 25 formed in the annular side wall portion 15 of the fitting portion 11 and penetrating the annular side wall portion 15 in the radial direction B. .. Further, both the ventilation groove 24 and the ventilation hole 25 shown in FIGS. 12A and 12B may be formed in the annular side wall portion 15.
