As shown in fig. 1 and 2, the heating appliance 100 includes: a warmer 2, a cover member 3, and an ear wearing tool 4 as an embodiment of the ear wearing tool of the present invention. Fig. 1 is an exploded perspective view of a warming appliance 100. Fig. 2 is a perspective view of the warming appliance 100 in a use state. The warming tool 100 can be distributed on the market in a state in which the warming body 2, the lid member 3, and the ear wearing tool 4 are separated into individual units (see fig. 1), or in a state in which the warming body 2 and the lid member 3 are attached to the ear wearing tool 4 (see fig. 2). The warmer 2, the lid member 3, and the ear wearing tool 4 constituting the warmer 100 may be distributed separately on the market.
Fig. 3 is a view showing a state in which the warming appliance 100 in the use state shown in fig. 2 is worn on the ear of the user. As shown in fig. 3, the warming device 100 of the present embodiment can be used by being worn on the ear. The warming tool 100 is capable of warming a predetermined portion of the ear by the warming body 2 in a state of being worn on the ear of the user, and a detailed structure will be described below. By warming ears, poor blood circulation can be improved, and symptoms such as dizziness, tinnitus, headache, and shoulder stiffness (hereinafter referred to as "dizziness and the like") can be expected to be improved. In addition, by warming the ears, the parasympathetic nerves inside can be stimulated by heating, and a relaxation effect can be obtained.
As shown in fig. 3, in the warming device 100 of the present embodiment, the lid member 3 is inserted into an external auditory meatus EA, so-called an ear hole, and the ear wearing device 4 is fitted into a concha ca (concha auriculae) of an auricle au (auricle) and can be fixed to an ear. The warming device 100 of the present embodiment is fixed to the ear in this manner, and thereby worn on the ear. However, the fixing method of the warming device 100 is not particularly limited as long as it can be worn on the ear. The warming tool 100 may be fixed to the ear only by being inserted into the external ear cavity EA and closely fitting to the inner surface of the external ear cavity EA, for example. The warming tool 100 may be fixed to the ear only by being fitted into the concha CA and closely attached to the inner surface of the concha CA. The heating tool 100 may be fixed to the ear by holding any part of the auricle AU other than the concha CA.
The warmer 2, the lid member 3, and the ear wearing device 4 of the warmer 100 will be described in detail below.
[ Warm body 2]
Fig. 4 is a diagram showing an individual body of the thermal body 2. The warmer 2 of the present embodiment is a disposable warming sheet (warmer). The warmer 2 is sealed in an air-tight film bag before use. The warmer 2 before use can be sealed in the film bag as the warmer 2 alone, or can be sealed in the film bag together with the ear wearing tool 4 in a state of being attached to the ear wearing tool 4 in advance.
The warmer 2 according to the present embodiment includes: a heat generating composition 5 which causes a chemical reaction accompanied by heat generation when it comes into contact with air, and a container 6 which contains the heat generating composition 5 therein. The heat-generating composition 5 may contain, for example, in appropriate amounts: oxidizable metal (iron powder, etc.), activated carbon, carbon black, water-retaining agent (wood powder, vermiculite, diatomaceous earth, perlite, silica gel, alumina, water-absorbent resin, etc.), metal salt (salt, etc.), water, etc. The housing 6 of the present embodiment includes a1 st sheet 6a and a 2 nd sheet 6b, and the 1 st sheet 6a and the 2 nd sheet 6 sandwich the heat generating composition 5 therebetween and house the heat generating composition. The 1 st sheet 6a and the 2 nd sheet 6b are joined at their peripheral edges by, for example, joining, welding, or the like, with the heat-generating composition 5 interposed therebetween.
The 1 st sheet 6a is hat-shaped, the 2 nd sheet 6b is circular flat, and the 1 st sheet 6a and the 2 nd sheet 6b sandwich the heat-generating composition 5 therebetween. The thermal body 2 of the present embodiment is attached to the ear wearing tool 4 in such a manner that the 1 st sheet 6a is covered with the ear wearing tool 4 (see fig. 9), and the detailed structure will be described later. On the other hand, the warmer 2 of the present embodiment is attached to the ear wearing tool 4 with the 2 nd sheet 6b exposed to the outside (see fig. 3 and 9).
In the present embodiment, the air permeability of the 1 st sheet 6a is higher than that of the 2 nd sheet 6 b. In this way, in a state where the warmer 2 is attached to the ear wearing device 4, heat dissipation through the second sheet 6b exposed to the outside can be suppressed. In particular, in the present embodiment, the 1 st sheet 6a is preferably a moisture-permeable sheet, and the 2 nd sheet 6b is preferably a non-moisture-permeable sheet.
The 1 st sheet 6a may be made of a material having high air permeability, for example, or may be made of a material having a vent hole formed therein as appropriate. As examples of the material constituting the 1 st sheet 6a, there can be cited: woven cloth, non-woven cloth, synthetic resin, rubber, elastomer, and the like. The 2 nd sheet 6b may be made of a material having low air permeability, for example. As examples of the material constituting the 2 nd sheet 6b, there can be cited: synthetic resin, a laminate of synthetic resin and woven or nonwoven fabric, and the like.
Examples of the fibrous material constituting the woven or nonwoven fabric having high air permeability include: synthetic fibers such as nylon, vinylon, polyester, rayon, acrylic, polyethylene, polypropylene, acetic acid, polyvinyl chloride, and polybutylene terephthalate, natural fibers such as cotton, hemp, silk, and paper, and mixed fibers of synthetic fibers and natural fibers. These fiber materials may be used alone, or 2 or more kinds may be used in combination.
As the material constituting the synthetic resin having low air permeability, for example, the same material as the resin material exemplified in the above-described fiber material can be used. Therefore, the 2 nd sheet 6b may be, for example, a resin film made of a resin material exemplified as the above-described fiber material. The 1 st sheet 6a may be a resin film similar to the 2 nd sheet 6b, which is formed with vent holes as appropriate.
As described above, the heat generating body 2 of the present embodiment is configured to include the heat generating composition 5 that causes a chemical reaction involving heat generation when it comes into contact with air, but is not limited to such a configuration. The thermal body 2 may be any structure that can store heat for a predetermined period of time, and may be used by being heated in a microwave oven, for example. The warm body 2 may use the heat of solidification of an aqueous solution of sodium acetate that is in a supercooled state at room temperature, for example.
In the heat generating body 2 of the present embodiment, the housing 6 for housing the heat generating composition 5 is composed of the 1 st sheet 6a and the 2 nd sheet 6b, but is not limited thereto. The structure of the housing 6 is not particularly limited as long as the heat generating composition 5 is housed and held in a manner corresponding to the structure of the ear wearing device 4.
Hereinafter, a portion of the thermal body 2 of the present embodiment, which accommodates the heat generating composition 5, is referred to as a body portion 2a of the thermal body 2. The main body 2a of the present embodiment has an outer shape of a substantially truncated cone shape, but the outer shape is not particularly limited. In addition, hereinafter, a portion of the thermal body 2 of the present embodiment that protrudes from the main body portion 2a is referred to as a held portion 2 b. The held portion 2b of the present embodiment is a flange portion that protrudes outward in the radial direction from the end portion on the large diameter side of the main body portion 2a in the shape of a truncated cone. The held portion 2b of the present embodiment is formed by the peripheral edge portions of the 1 st sheet 6a and the 2 nd sheet 6 b.
[ cover Member 3]
As shown in fig. 1 and 2, the cover member 3 is configured to be attachable to an insertion portion 12 of the ear wearing device 4, which will be described later. More specifically, the lid member 3 of the present embodiment includes: a mounting cylindrical portion 3a into which the insertion portion 12 of the ear wearing device 4 is fitted (see fig. 9); and an outer covering tube portion 3b connected to the mounting tube portion 3a so as to be folded back from the distal end of the mounting tube portion 3 a.
The insertion portion 12 of the ear wearing device 4 is inserted from the opening of the cap member 3 on the proximal end side of the mounting cylindrical portion 3a toward the inside. The insertion portion 12 is in close contact with the inner surface of the mounting cylindrical portion 3a, and can hold the mounting cylindrical portion 3 a. The insertion portion 12 of the ear wearing device 4 of the present embodiment includes the annular protrusion 12b 1. The annular convex portion 12b1 of the insertion portion 12 is fitted into an annular concave portion 3a1 (refer to fig. 9) provided on the inner surface of the mounting cylinder portion 3a, and the detailed structure will be described later. This can improve the holding property of the cover member 3 by the insertion portion 12.
The outer cylindrical portion 3b covers the outer side in the radial direction of the mounting cylindrical portion 3 a. An annular space is defined between the mounting tube 3a and the outer tube 3 b. Therefore, when inserted into the external ear hole EA as shown in fig. 3, the external cylindrical portion 3b is pressed against the inner surface of the external ear hole EA, and thus, while elastically deforming radially inward so as to approach the outer surface of the mounting cylindrical portion 3a, comes into close contact with the inner surface of the external ear hole EA. As described above, by attaching the cover member 3 to the ear wearing device 4, the cover member 3 is fitted in the external ear hole EA so as to be in close contact with the inner surface of the external ear hole EA, and the fixing property of the warming device 100 to the external ear hole EA can be improved. Further, by using the cover member 3, the external ear hole EA can be closed, and the sound insulation can be improved. This can block external noise and the like, and can make the user wearing the warming device 100 easily relax.
The material constituting the lid member 3 is not particularly limited, and examples thereof include: rubbers, elastomers, synthetic resins including soft resins and hard resins, and the like. Examples of the synthetic resin include polypropylene (PP), Polyethylene (PE), and polyethylene terephthalate (PET). In the lid member 3 of the present embodiment, the mounting tube portion 3a and the outer tube portion 3b are integrally formed of the same material, but may be formed of different materials. The lid member 3 may be formed by mixing a metal, carbon, or other material into a base material such as rubber, elastomer, or synthetic resin. Further, the cover member 3 may be formed of a thermally conductive resin.
[ ear wearing device 4]
The ear wearing device 4 is configured to be able to attach the above-described warmer 2 and the cover member 3. The ear wearing tool 4 is configured to be worn on the ear together with the thermal body 2 and the cover member 3 attached thereto. The phrase "the ear wearing tool 4 can be worn on the ear" includes not only the ear wearing tool 4 itself directly fixed to the ear but also the ear wearing tool 4 indirectly fixed to the ear through another member such as the cover member 3 that can be fixed to the ear.
Fig. 5(a) is a plan view of the ear wearing device 4 alone as viewed from the upper surface side. Fig. 5(b) is a bottom view of the individual ear-worn device 4 viewed from the lower surface side. Here, the "upper surface" of the ear wearing device 4 refers to a surface located on the auricle AU (see fig. 3) side in a state where the ear wearing device 4 is worn on the ear. The "lower surface" of the ear wearing device 4 refers to a surface on the opposite side of the upper surface. Fig. 6 is a cross-sectional view of the ear wearing device 4 at the position of line I-I shown in fig. 5(a) and 5 (b). Fig. 7 is a sectional view of the ear wearing device 4 at the position of line II-II shown in fig. 5(a) and 5 (b). Fig. 8 is a cross-sectional view of the ear wearing device 4 at the position of line III-III shown in fig. 5(a) and 5 (b). The ear wearing device 4 will be described in detail below with reference to fig. 1 to 3 and 5 to 8.
As shown in fig. 1 and the like, the ear wearing device 4 of the present embodiment includes: an insertion portion 11, an insertion portion 12, a holding portion 13, and a connecting flange portion 20.
< insert part 11 >
The fitting portion 11 can be fitted into the concha CA of the auricle AU in a state where the ear wearing device 4 is worn on the ear (see fig. 3). The insertion portion 11 is configured to come into contact with the inner surface of the concha CA of the auricle AU in a state where the ear wearing device 4 is worn on the ear (see fig. 3). The insertion portion 11 of the thermal body 2 warms the inner surface of the concha CA of the auricle AU, thereby improving poor blood circulation and improving symptoms such as dizziness. In addition, the heating stimulates the parasympathetic nerves inside, thereby obtaining a relaxing effect.
More specifically, the insertion portion 11 of the present embodiment is configured to contact the inner surface of the concha cavity in the inner surface of the concha CA by being inserted into the concha CA. The thermal body 2 can effectively heat the parasympathetic nerves inside by heating the inner surface of the concha CA, particularly the inner surface of the concha cavity, by the insertion portion 11. Thereby, the relaxation effect described above can be further improved.
Hereinafter, for convenience of explanation, the extending direction of the fitting portion 11 is referred to as "height direction a of the fitting portion 11", or simply as "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 below. Hereinafter, for the sake of convenience of explanation, a 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". In addition, a direction from the distal end side to the proximal end side of the fitting portion 11 in the height direction a of the fitting portion 11 may be simply referred to as "lower side". The upper side of the present embodiment is an end side of the annular side wall portion 15 (see fig. 1 and the like) connected to a top plate portion 16 (see fig. 1 and the like) as described below. The lower side of the present embodiment refers to the annular side wall portion 15 on the other end side opposite to the one end side connected to the top plate portion 16.
As shown in fig. 5 to 8, the fitting portion 11 of the present embodiment defines a housing space 15a therein, and the housing space 15a can house the warmer 2 that heats the inner surface of the concha CA by the fitting portion 11. The insertion portion 11 of the present embodiment includes: a convex surface contacting the inner surface of the concha CA, and a concave surface defining the housing 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 fitted to the concha CA. In particular, the annular side wall portion 15 of the present embodiment can be fitted so as to be sandwiched by the inner surfaces of the conchas CA. More specifically, the annular side wall portion 15 of the present embodiment can be fitted so as to be sandwiched between the inner surfaces of the concha cavities among the inner surfaces of the conchas CA. The annular side wall portion 15 defines a housing space 15a in which the main body portion 2a (see fig. 4) of the thermal body 2 can be housed. The top plate 16 is connected to one end (hereinafter, referred to as "upper end") of the annular side wall 15 on the upper side. The upper end of the housing space 15a of the annular side wall 15 is closed by a top plate 16. In other words, the housing space 15a of the present embodiment is a truncated conical space defined by the annular side wall portion 15 and the top plate portion 16. The top plate 16 has a contact surface 16a, and the contact surface 16a can contact 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 conchas CA. The contact surface 16a of the top plate 16 of the present embodiment is constituted by a top plate upper surface 17a on the opposite side of the top plate lower surface 17b facing the housing space 15a in the top plate 16.
The above-described warmer 2 can be attached to the ear wearing device 4 by housing the main body 2a in the housing space 15 a. Specifically, the main body 2a of the thermal body 2 can be housed in the housing space 15a from an open end of the annular side wall portion 15, which is an end (hereinafter, referred to as "lower end") on a lower side of the annular side wall portion 15 on a side opposite to an upper end connected to the top plate portion 16.
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 insertion portion 11 may be, for example, a cylindrical shape. The outer shape of the insertion portion 11 may be, for example, a shape matching the inner surface of the concha CA. Therefore, the annular side wall portion 15 of the fitting portion 11 is not limited to the tapered cylindrical shape of the present embodiment. The annular side wall portion 15 may have a cylindrical shape having the same inner diameter and outer diameter at any position in the central axis direction. However, the outer surface of the annular side wall portion 15 preferably has a tapered shape that tapers from a lower end opposite to the upper end connected to the top plate portion 16 toward the upper end connected to the top plate portion 16, as in the present embodiment. This facilitates the fitting of the fitting portion 11 to the concha CA. The annular side wall portion 15 may have a cross-sectional outer shape perpendicular to the height direction a, which is not circular, but may be an amorphous shape matching the inner surface of the concha CA. Further, the top plate 16 of the present embodiment is constituted by a flat plate portion having a circular flat shape that closes the upper end of the annular side wall portion 15 having a tapered cylindrical shape, but is not limited to this configuration. The top plate 16 is preferably configured to increase the area of the contact surface 16a that contacts the bottom surface of the concha CA. Therefore, the top plate 16 may be formed of a curved plate portion curved in a dome shape, for example, so that the contact surface 16a is convex. Further, although the housing space 15a of the present embodiment is a space having a substantially truncated cone shape, the shape of the housing space 15a is not particularly limited. The housing space 15a of the present embodiment may be configured to be able to house at least a part of the thermal body 2 and to be able to heat the auricle AU through the insertion portion 11. In the present embodiment, the main body 2a of the heater 2 is housed in the housing space 15a, and is covered with the annular side wall portion 15 and the top plate portion 16.
< insertion part 12 >
As shown in fig. 5, 6, and the like, the insertion portion 12 protrudes from the insertion portion 11. The insertion portion 12 is configured to be insertable into an external ear hole EA (see fig. 3) together with the cover member 3 attached thereto. Specifically, the insertion portion 12 of the present embodiment protrudes outward from the fitting portion 11 in a plan view (see fig. 5(a) and 5(b)) viewed in the height direction a of the fitting portion 11. More specifically, the insertion portion 12 of the present embodiment is provided to protrude from the annular side wall portion 15 of the fitting portion 11 toward the outside in the radial direction B of the annular side wall portion 15. Hereinafter, for convenience of explanation, the radial direction B of the annular side wall portion 15 may be simply referred to as "radial direction B".
The insertion portion 12 of the present embodiment includes: a proximal end portion 12a connected to the annular side wall portion 15, and a distal end portion 12b connected to the proximal end portion 12a and insertable into an attachment cylindrical portion 3a (see fig. 9) of the lid member 3. The distal end portion 12b has a substantially cylindrical outer shape. The central axis direction C as the extending direction of the distal end portion 12b is inclined with respect to the height direction a of the fitting portion 11. The distal end portion 12b is insertable into the mounting cylindrical portion 3a of the cover member 3 to press and expand the mounting cylindrical portion 3a outward in the radial direction. Thereby, the outer surface of the distal end portion 12b is brought into close contact with the inner surface of the mounting tube portion 3 a. As a result, the cover member 3 is held by the insertion portion 12 of the ear wearing device 4. In addition to the outer tubular portion 3b being in close contact with the inner surface of the external ear hole EA, the external ear hole EA can be further closed by the close contact between the outer surface of the distal end portion 12b and the inner surface of the mounting tubular portion 3a, and the sound insulation of the warming tool 100 can be further improved.
Further, the distal end portion 12b of the present embodiment includes an annular convex portion 12b1 that protrudes outward in the radial direction. When the distal end portion 12b of the insertion portion 12 is inserted into the mounting cylindrical portion 3a of the lid member 3, the annular convex portion 12b1 of the distal end portion 12b fits into the annular concave portion 3a1 (see fig. 9) provided on the inner surface of the mounting cylindrical portion 3 a. This makes it difficult for the mounting tube 3a to fall off from the distal end portion 12 b. Therefore, the holding property 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 lid member 3 so as to be able to attach the lid member 3 described above, but may be formed integrally. Therefore, the distal end portion 12b of the insertion portion 12 of the present embodiment may be formed to be integrally connected to the mounting cylindrical portion 3a of the lid member 3, for example.
The ear wearing device 4 of the present embodiment includes the insertion portion 12, but is not limited to this configuration. The ear wearing device 4 of the present embodiment is configured to be fixed to the ear by being brought into close contact with the inner surface of the external auditory meatus EA, but if the ear wearing device 4 fixed only by the auricle AU is used, for example, the ear wearing device 4 may not include the insertion portion 12. However, from the viewpoint of relaxation effect due to sound insulation, the warming tool 100 preferably includes an insertion portion 12 that can be inserted into the external ear cavity EA. The heating tool 100 preferably further includes a lid member 3 that can be attached to the insertion portion 12, from the viewpoint of improving the adhesion to the inner surface of the outer ear hole EA. In this way, the relaxation effect due to the sound insulating property can be further improved. Although the insertion portion 12 of the present embodiment is formed integrally with the insertion portion 11, it may be formed separately from the insertion portion 11 and detachably attached to the insertion portion 11.
< holding part 13 >
The holding portion 13 can hold the warmer 2 that heats the inner surface of the concha CA of the auricle AU by the insertion portion 11. In other words, the thermal body 2 held by the holding portion 13 of the present embodiment can heat the inner surface of the concha CA of the auricle AU through the fitting portion 11.
As shown in fig. 5(b), the holding portion 13 of the present embodiment includes: a support portion 18 that supports the thermal body 2 from below, and a restriction wall portion 19 that restricts movement of the thermal body 2 in a direction orthogonal to the height direction a.
More specifically, as shown in fig. 6 to 8, the support portion 18 of the present embodiment includes: a flat plate-like support plate portion 18a located below the lower end of the fitting portion 11 and extending in a direction orthogonal to the height direction a; and a support protrusion 18B protruding from the limiting wall 19 inward in the radial direction B. The held portion 2b of the thermal body 2 is supported from below by the support plate portion 18a and the support protrusion portion 18b in a state where the main body portion 2a is accommodated in the accommodation space 15a (hereinafter, may be simply referred to as an "accommodated state"). Therefore, the support plate portion 18a and the support protrusion portion 18b are provided at positions that do not overlap with the housing space 15a in the height direction a. More specifically, the support plate portion 18a and the support projection 18B of the support portion 18 of the present embodiment are provided at positions outside the housing space 15a in the radial direction B.
The restricting wall 19 is connected to the outside of the support portion 18 in the radial direction B and extends upward in the height direction a. More specifically, as shown in fig. 6 to 8, the restricting wall 19 of the present embodiment includes: a1 st regulating wall portion 19a connected to the outer side of the support plate portion 18a in the radial direction B and extending upward in the height direction a; and a 2 nd regulating wall portion 19B connected to the outer side of the support protrusion portion 18B in the radial direction B and extending upward in the height direction a. The 1 st and 2 nd limiting wall parts 19a and 19B are located outside the held part 2B in the radial direction B in a state where the held part 2B of the thermal body 2 is supported from below by the support plate part 18a and the support protrusion part 18B. Therefore, in a state where the main body portion 2a is accommodated in the accommodation space 15a and the held portion 2b is supported from below by the support plate portion 18a and the support protrusion portion 18b, the movement of the held portion 2b of the thermal body 2 in the direction orthogonal to the height direction a is restricted by the 1 st restriction wall portion 19a and the 2 nd restriction wall portion 19 b.
As described above, the holding portion 13 of the present embodiment can hold the thermal body 2 by restricting the movement of the lower side of the held portion 2b of the thermal body 2 in the height direction a and the movement in the direction orthogonal to the height direction a by the support portion 18 and the restricting wall portion 19. The movement of the held portion 2b of the thermal body 2 to the upper side in the height direction a is restricted by the lower end of the fitting portion 11 described above. In particular, in the ear wearing device 4 of the present embodiment, the connection flange portion 20 is provided as a flange portion that protrudes outward in the radial direction B from the open end that is the lower end of the fitting portion 11 described above and connects the fitting portion 11 and the 2 nd regulating wall portion 19B of the holding portion 13. In the present embodiment, the flange portion 20 is connected to restrict movement of the held portion 2b of the thermal body 2 upward in the height direction a together with the lower end of the fitting portion 11. However, the ear wearing device 4 is not limited to the connection flange portion 20 of the present embodiment as long as it has a portion for connecting the fitting portion 11 and the holding portion 13. Therefore, the movement of the held portion 2b of the thermal body 2 upward in the height direction a may be restricted by the lower end of the fitting portion 11 described above, and is not necessarily restricted by the connecting flange portion 20.
In the ear wearing device 4 of the present embodiment, the fitting portion 11 is connected to the 2 nd regulating wall portion 19b via the connecting flange portion 20. A support protrusion 18B protrudes from the 2 nd regulating wall 19B inward in the radial direction B. The 2 nd restricting wall 19b is connected to the support plate 18 a. Further, a1 st regulating wall portion 19a is connected to an outer edge of the support plate portion 18 a. In this manner, in the ear wearing device 4 of the present embodiment, the fitting portion 11 and the holding portion 13 are connected by the connecting flange portion 20. Although the fitting portion 11 and the holding portion 13 are integrally formed with the connecting flange portion 20 interposed therebetween in the present embodiment, at least one of the fitting portion 11, the holding portion 13, and the connecting flange portion 20 may be formed separately and joined by bonding, 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 insertion portion 12 described above with a gap therebetween in the height direction a. The holding portion 2B of the thermal body 2 can be 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 toward the outside in the radial direction B. As shown in fig. 6, the 1 st regulating wall portion 19a extends upward from the outer edge portion of the support plate portion 18a on the outer side in the radial direction B, and is connected to the base end portion 12a of the insertion portion 12.
< connecting flange portion 20 >
As described above, the ear wearing device 4 of the present embodiment includes the connection flange portion 20 as the flange portion in addition to the fitting portion 11, the insertion portion 12, and the holding portion 13. The connection flange portion 20 of the present embodiment is connected to the insertion portion 11. More specifically, the connecting flange portion 20 of the present embodiment projects outward in the radial direction B from the lower end of the fitting portion 11, and connects the fitting portion 11 and the 2 nd 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 includes a wall connecting end portion 20b connected to the 2 nd limiting wall portion 19b (see fig. 5 b) of the limiting wall portion 19 that covers the periphery of the held portion 2b of the heating body 2 in the stored state, and further includes a free end portion 20a that is not connected to the 2 nd limiting wall portion 19b of the limiting wall portion 19. Further, a 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 a 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 fig. 5(b), 6, and 7, a vent groove 21 extending from the position of the free end portion 20a to the housing space 15a is formed in the lower surface of the connecting flange portion 20. Therefore, in the present embodiment, the vent groove 21 defines the vent path 30, and the vent path 30 is connected from the position where the free end portion 20a of the flange portion 20 is connected to the recess provided at the opening end of the lower end of the fitting portion 11, and communicates with the housing space 15 a. Therefore, even when the held portion 2b of the thermal element 2 is in contact with the open end of the fitting portion 11 and the lower surface of the connecting flange portion 20 in the accommodated state in which the main body portion 2a of the thermal element 2 is accommodated in the accommodating space 15a, air can be made to enter the accommodating space 15a through the vent groove 21. Therefore, even when the main body 2a containing the heat generating composition 5 (see fig. 4) that generates heat by contacting air is housed in the housing space 15a, air can be caused to enter the housing space 15a by the ventilation groove 21, and heat can be generated. In the ear-worn device 4 of the present embodiment, the ventilation channel 30 is defined by the ventilation groove 21, but the ventilation channel 30 is not limited to the configuration of the present embodiment (see fig. 11 and 12). The detailed structure of the ventilation path 30 of the present embodiment will be described below.
In the present embodiment, as shown in fig. 2, in a state where the thermal body 2 is attached to the ear wearing device 4, a part of the held portion 2B of the thermal body 2 is exposed to the outside in the radial direction B from the free end portion 20 a. Therefore, when the thermal body 2 is to be taken out from the ear wearing device 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. In this way, the thermo-thermal body 2 can be easily taken out from the ear wearing device 4.
As shown in fig. 5a, the connecting flange portions 20 of the present embodiment are not provided at positions on both sides of the insertion portion 12 in the circumferential direction D of the fitting portion 11 (in the present embodiment, in the same direction as the circumferential direction of the annular side wall portion 15, and hereinafter, simply referred to as "circumferential direction D"). Therefore, the ear wearing device 4 of the present embodiment is configured such that the upper surface of the support plate portion 18a is visible in a plan view shown in fig. 5 (a). The thermal body 2 of the present embodiment can be attached to the ear wearing device 4 by inserting the held portion 2B from the inside toward the outside in the radial direction B between the lower surface of the proximal end portion 12a of the insertion portion 12 and the upper surface of the support plate portion 18 a. Therefore, by not providing the connecting flange portions 20 on both sides of the insertion portion 12 in the circumferential direction D, it can be confirmed from the outside whether or not the held portion 2b of the thermal body 2 is properly 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 18 a.
The ear wearing device 4 of the present embodiment includes the connecting flange portion 20 protruding outward in the radial direction B from the open end, which is the lower end of the fitting portion 11, in order to connect the fitting portion 11 and the holding portion 13, but is not limited to the configuration of the connecting flange portion 20 of the present embodiment as long as the fitting portion 11 and the holding portion 13 are connected. However, it is preferable to use the connecting flange portion 20 having a lower surface positioned flush with the lower end of the fitting portion 11 in the height direction a, as in the present embodiment. In this way, in the accommodated state in which the main body portion 2a of the thermal body 2 is accommodated in the accommodating space 15a, the flange-shaped held portion 2b of the thermal body 2 can be suppressed from moving so as to be inclined with respect to the height direction a. As a result, the main body 2a of the thermal body 2 is less likely to fall out of the housing space 15 a. Therefore, the positional stability of the thermal body 2 in the state where the holding portion 13 holds the held portion 2b of the thermal body 2 can be further improved.
The material constituting the ear wearing device 4 is not particularly limited, and examples thereof include: rubbers, elastomers, synthetic resins including soft resins and hard resins, and the like. More specifically, there may be enumerated: polypropylene (PP), Polyethylene (PE), polyethylene terephthalate (PET), elastomers, and the like. The ear wearing device 4 may be made of a material having high thermal conductivity, because the heat of the thermal body 2 is efficiently transmitted to the auricle AU (see fig. 3). Examples of such a material include a material having high thermal conductivity such as metal or carbon mixed with a base material such as rubber, elastomer, or synthetic resin, thereby improving the thermal conductivity. In addition, a thermally conductive resin having high thermal conductivity may be used.
[ air passage 30]
Next, the ventilation path 30, which communicates the outside with the housing space 15a in a state where the thermal body 2 is housed in the housing space 15a, will be described. Fig. 9 is a sectional view of the warming device 100 in a state in which the warming body 2 and the lid member 3 are attached to the ear wearing device 4. Fig. 9 shows a cross section at the same position as the line I-I in fig. 5 in a state where the warmer 2 and the cover member 3 are attached to the ear wearing tool 4. Fig. 10 is a sectional view showing a state in which the warmer 2 is attached to the ear wearing device 4 at the same position as in fig. 9.
First, a state in which the ear wearing device 4 holds the warmer 2 as shown in fig. 9 will be described in detail. As shown in fig. 9, the holding portion 13 of the present embodiment can hold the thermal body 2 that heats the inner surface of the concha CA (see fig. 3) of the auricle AU (see fig. 3) by the fitting portion 11. In the present embodiment, as described above, in the accommodated state in which the main body 2a of the thermal body 2 is accommodated in the accommodating space 15a, the support portion 18 and the regulating wall portion 19 of the holding portion 13 hold the held portion 2b of the thermal body 2.
Here, the holding portion 13 restricts the movement of the thermal body 2 relative to the ear wearing device 4 within a predetermined range so that the thermal body 2 does not separate from the ear wearing device 4. That is, the structure of the holding portion 13 is not limited to the structure that holds the warm heat body 2 so that the warm heat body 2 does not move at all with respect to the ear wearing device 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, the holding portion 13 of the present embodiment holds the thermal body 2 so that the thermal body 2 can move in the height direction a within a range from a position where the lower surface of the held portion 2b is supported in contact with the support plate portion 18a and the support protrusion portion 18b to a position where the upper surface of the held portion 2b is in contact with the lower end of the fitting portion 11 and the lower surface of the connecting flange portion 20. Fig. 9 shows a holding position in which the upper surface of the held portion 2b of the thermal body 2 is positioned on the uppermost side, and the thermal body 2 is in contact with the open end, which is the lower end of the fitting portion 11, and the lower surface of the connecting flange portion 20.
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 where the held portion 2b of the thermal body 2 cannot move in the direction orthogonal to the height direction a. Specifically, in the present embodiment, the 1 st and 2 nd regulating wall portions 19a and 19b of the regulating wall portion 19 are located around the held portion 2b of the thermal body 2 in the direction orthogonal to the height direction a. Therefore, the 1 st regulating wall portion 19a and the 2 nd regulating wall portion 19b of the regulating wall portion 19 come into contact with the outer edge of the held portion 2b of the thermal body 2, thereby regulating the movement of the thermal body 2 in the direction orthogonal to the height direction a. 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 can hold the thermal body 2 in a state of being spaced apart from the fitting portion 11 via the gap X. In the case where the holding portion 13 holds the thermal body 2 so as to be movable within a predetermined range as in the present embodiment, the thermal body 2 located at an arbitrary position within the predetermined movable range may be formed to be spaced apart from the fitting portion 11 via the gap X. Although fig. 9 shows a state in which the thermal body 2 is positioned at the uppermost holding position, even in this state, the main body 2a of the thermal body 2 of the present embodiment is kept spaced apart from the annular side wall portion 15 and the top plate portion 16 of the fitting portion 11 via the gap X. This can suppress a rapid temperature rise of the insertion portion 11 due to the hot body 2, and can avoid scalding of the inner surface of the concha CA of the auricle AU coming into contact with the insertion portion 11.
The holding portion 13 of the present embodiment holds the thermal element 2 in a state where the thermal element 2 is accommodated inside the annular side wall portion 15 from the side of the ceiling lower surface 17b, which is the rear surface side of the ceiling upper surface 17a, that is, the contact surface 16a of the ceiling portion 16. By adopting the structure in which the holding portion 13 holds the warm heat element 2 accommodated in the accommodation space 15a in the annular side wall portion 15 as described above, the warm heat element 2 can be easily attached to the ear wearing device 4.
More specifically, as shown in fig. 9, the holding portion 13 of the present embodiment holds the held portion 2b protruding from the main body portion 2a of the thermal body 2 in a state where the main body portion 2a of the thermal body 2 is accommodated inside the annular side wall portion 15 from the ceiling lower surface 17b side of the ceiling portion 16. Thus, as described above, the thermal body 2 can be easily attached to the ear wearing device 4. Further, the held portion 2b of the warm heat element 2 is brought into contact with the lower end of the annular side wall portion 15, which is the lower end of the fitting portion 11, whereby the amount of pressing the main body portion 2a into the annular side wall portion 15 can be limited. This can easily secure the gap X between the main body 2a of the thermal body 2 and the top plate 16.
As shown in fig. 10, in the heating tool 100 of the present embodiment, the flange portion serving as the held portion 2B of the heating element 2 is inserted into the gap between the support plate portion 18a and the insertion portion 12 from the inside toward the outside in the radial direction B, and the main body portion 2a of the heating element 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. The portion of the held portion 2b of the thermal body 2 other than the portion inserted into the gap between the support plate portion 18a and the insertion portion 12 passes over the support protrusion portion 18b, that is, the held portion 2b is held by the holding portion 13, whereby the body portion 2a is completely accommodated in the annular side wall portion 15.
As shown in fig. 9, the holding portion 13 of the present embodiment holds the thermal body 2 in a state where the main body portion 2a of the thermal body 2 is covered with the fitting portion 11. As described above, by covering the main body 2a of the thermal body 2 with the insertion portion 11, it is possible to avoid wasteful dissipation of heat generated by the main body 2a for heating the insertion portion 11 without consuming the heat.
The fitting portion 11 preferably covers at least the surface of a heating portion of the heating element 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 of the heating body 2, which is a heating portion that heats the fitting portion 11, may be covered, and the held portion 2b, which is not a heating portion, may not be covered.
Next, the vent groove 21 defining the vent passage 30 will be described. The ear wearing device 4 defines a ventilation path 30, and the ventilation path 30 communicates the outside with the housing space 15a in a state where the warmer 2 is housed in the housing space 15 a. The ventilation path 30 of the present embodiment is defined by the ventilation groove 21 described above, but is not limited to this configuration. The detailed structure thereof will be described below (refer to fig. 11 and the like). By providing the air passage 30 capable of supplying air to the housing space 15a of the fitting portion 11 in the ear wearing device 4, even the thermal body 2 that generates heat by supplying air into the housing space 15a can be used by being attached to the ear wearing device 4. Therefore, the concha CA can be heated efficiently by the thermo-thermal body 2 regardless of the kind of the thermo-thermal body 2.
The heating element 2 of the present embodiment is configured to generate heat by supplying air into the housing space 15 a. Specifically, in the main body 2a of the heating element 2 of the present embodiment, air enters from the surface of the air-permeable sheet 1 on the 6a side, and thus the heat generating composition 5 inside can generate heat. Therefore, as in the present embodiment, when the surface of the main body 2a on the 1 st sheet 6a side is housed in the housing space 15a in the insertion portion 11, it is necessary to supply air into the housing space 15a from the outside. As described above, in the warming tool 100 of the present embodiment, the flange-like held portion 2b of the warming body 2 is held by the holding portion 13 in a state in which it can be brought into contact with the lower end of the fitting portion 11 and the lower surface of the connecting flange portion 20 of the ear wearing tool 4. Therefore, if the entire circumferential region of the open end of the lower end of the insertion portion 11 is in contact with the flange-like held portion 2b of the heat block 2, air cannot enter the housing space 15a from the open end of the insertion portion 11.
Therefore, the vent passage 30 of the present embodiment is defined by the vent groove 21 that faces the held portion 2b of the thermal body 2 in the accommodated state in which the main body portion 2a of the thermal body 2 is accommodated in the accommodating space 15a, and extends so as to straddle the open end of the fitting portion 11 and the lower surface of the facing surface (the surface facing the held portion 2 b) of the connecting flange portion 20. As a result, as shown in fig. 9, even in a state where the flange-like held portion 2b of the warmer 2 is in contact with the lower end of the fitting portion 11 of the ear wearing tool 4 and the lower surface of the connecting flange portion 20, the ventilation path 30 defined by the ventilation groove 21 is not blocked. Therefore, air can enter the housing space 15a from the outside through the ventilation path 30.
The vent passage 30 of the present embodiment is defined by the vent groove 21 so as to extend over 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 modification of the ventilation path 30. As shown in fig. 11(a), the ventilation path 30 may be defined by, for example, a notch 22 formed across the fitting portion 11 and the connecting flange portion 20. The vent passage 30 may be defined by a vent hole extending through the fitting portion 11 and the connecting flange portion 20, for example. Further, as shown in fig. 11(b), the ventilation path 30 may be defined by only the insertion portion 11, for example. As shown in fig. 11(B), the vent passage 30 defined only by the fitting portion 11 may be defined by, for example, the vent holes 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. The size and number of the vent holes may be appropriately determined according to the required ventilation amount, and are not particularly limited.
As shown in fig. 5(b), 9, and the like, the vent groove 21 of the present embodiment extends from an inner end connected to the housing space 15a to an outer end connected to the outside at a position where the free end 20a of the outer edge of the flange portion 20 is connected. Thus, the outer end of the vent groove 21 is not covered by the 2 nd regulating wall 19b of the regulating wall 19. Therefore, ventilation by the ventilation path 30 defined by the ventilation groove 21 is easily ensured. As shown in fig. 5(a), 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. Therefore, the length of the ventilation path 30 defined by the ventilation groove 21 can be shortened, and ventilation passing through the space between the outside of the ventilation path 30 and the housing space 15a can be more easily ensured.
Further, as shown in fig. 5(b), the ventilation path 30 of the present embodiment may be provided at a position different from the position where the insertion portion 12 is provided in the circumferential direction D. Therefore, even when the warming device 100 is worn on the ear, the outer end of the air vent groove 21 is easily exposed to the outside, and ventilation by the ventilation path 30 defined by the air vent groove 21 is easily ensured.
More specifically, as shown in fig. 5(b), the ventilation path 30 of the present embodiment is provided at a position including the 2 nd position P2 in the circumferential direction D. Here, a position at which the insertion portion 12 protrudes outward from the fitting portion 11 in the circumferential direction D is referred to as "1 st position P1", and a position on the opposite side of the fitting portion 11 from the 1 st position P1 with respect to a plan view (see fig. 5a and 5 b) of the fitting portion 11 in the height direction a of the fitting portion 11 is referred to as "2 nd position P2". The 1 st position P1 is a midpoint in the circumferential direction D of the insertion portion 12 in the above-described plan view (see fig. 5(a) and 5 (b)).
However, the position of the ventilation path 30 is not limited to the position of the present embodiment. The ventilation path 30 may be provided between the 1 st position P1 and the 2 nd position P2 in the circumferential direction D. By providing the ventilation path 30 between the 1 st position P1 and the 2 nd position P2 in the circumferential direction D, the warming device 100 can be easily worn on the ear with the ventilation path 30 directed upward in the vertical direction. Therefore, the end of the ventilation path 30 is easily exposed to the outside, ventilation is easily ensured, and the ventilation path 30 is directed upward in the vertical direction, so that the ventilation path 30 can be prevented from being clogged with water vapor.
The ear wearing device and the warming device of the present invention are not limited to the specific configurations shown in the above-described embodiments, and various modifications and changes can be made without departing from the scope of the claims. The ear wearing device 4 of the above-described embodiment includes the connection flange portion 20 as the flange portion, but may be configured without the connection flange portion 20. In this case, as shown in fig. 12, the ventilation path 30 may be defined by the insertion portion 11, for example. Fig. 12 shows an example of the ventilation path 30 defined in the annular side wall portion 15 of the fitting portion 11. As shown in fig. 12(a), the vent passage 30 may be defined by a vent groove 24 formed at the opening end of the annular side wall portion 15. As shown in fig. 12(B), the ventilation path 30 may be defined 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, as shown in fig. 12(a) and 12(b), both the vent groove 24 and the vent hole 25 may be formed in the annular side wall portion 15.
