Description

Technical Field

[0001] This application relates to the field of physical therapy and healthcare, and in particular to a foldable ear dryer. Background Technology

[0002] In daily life, we often get water into our ear canals due to activities such as swimming and bathing. Due to the special structure of the ear canal, it is usually difficult to clean the water out. The common way to deal with this is to clean it with cotton swabs, but the ear canal is still difficult to dry.

[0003] Therefore, ear dryers have appeared on the market to dry the ear canal. These dryers work by drying the ear canal, keeping it dry and preventing bacterial growth and infection. Common ear dryers mainly consist of a housing and a mouthpiece. The dryer is built into the housing, and a control switch is located on the outer shell. Simply hold the housing, point the mouthpiece at your ear, and turn it on to use.

[0004] Although this ear dryer has a simple structure, it is bulky and inconvenient to carry. Furthermore, because the mouthpiece is exposed, it is easily damaged by external pressure. When traveling or on business trips, it is inconvenient to store the ear dryer separately if you need to carry cleaning supplies. Utility Model Content

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0030] This application discloses a foldable ear dryer. (See also...) Figure 1 and Figure 2 The foldable ear dryer includes a housing 1 and a nozzle 2. The housing 1 has cavities for accommodating the various components of the ear dryer, and the nozzle 2 is fixed to the housing 1. The housing 1 includes an upper housing 11 and a lower housing 12. One end of the upper housing 11 and one end of the lower housing 12 are hinged together. The nozzle 2 is fixed to the upper housing 11. The lower housing 12 has a receiving cavity 13 for storing the nozzle 2. The upper housing 11 or the lower housing 12 can be rotated around the hinge axis of the upper housing 11 and the lower housing 12 to fold the ear dryer, and the nozzle 2 is stored in the receiving cavity 13.

[0031] Reference Figure 3 The upper housing 11 includes an upper sleeve 111 and an upper side plate 112, and the lower housing 12 includes a lower sleeve 121 and a lower side plate 122. The upper sleeve 111 and the upper side plate 112 are fixedly connected and form a cavity for accommodating some components of the ear dryer. Similarly, the lower sleeve 121 and the lower side plate 122 are fixedly connected and form a cavity for accommodating some components of the ear dryer. The mouthpiece 2 is fixed to the upper side plate 112, and the receiving cavity 13 is formed on the lower side plate 122. The hinge axis of the upper housing 11 and the lower housing 12 is located at the junction of the upper side plate 112 and the lower side plate 122. The upper side plate 112 and the lower side plate 122 rotate around the hinge axis of the upper housing 11 and the lower housing 12 to open or fold the ear dryer. A fixing mechanism is provided between the upper side plate 112 and the lower side plate 122 to fix them together, so that the ear dryer can remain relatively fixed in the open or folded state.

[0032] Reference Figure 4 and Figure 5The upper side plate 112 includes an integrally formed upper bottom plate 113 and upper back plate 114, and the lower side plate 122 includes an integrally formed lower bottom plate 123 and lower back plate 124. When the upper side plate 112 or the lower side plate 122 is rotated to the point where the upper back plate 114 abuts against the lower back plate 124, it is in the retracted state of the ear dryer. When the upper side plate 112 or the lower side plate 122 is rotated to the point where the upper bottom plate 113 abuts against the lower bottom plate 123, it is in the open state of the ear dryer. The nozzle 2 is fixed on the upper back plate 114, and the lower back plate 124 is recessed towards the cavity of the lower housing 12 to form a receiving cavity 13. Preferably, the nozzle 2 is fixed at the end of the upper back plate 114 away from the hinge axis of the upper housing 11 and the lower housing 12, and the receiving cavity 13 is located at the end of the lower back plate 124 away from the hinge axis of the upper housing 11 and the lower housing 12.

[0033] Reference Figure 6 The fixing structure includes a first fixing component and a second fixing component. The first fixing component is used to fix the upper housing 11 and the lower housing 12 in the stored state, and the second fixing component is used to fix the upper housing 11 and the lower housing 12 in the open state. In one embodiment, the first fixing component is a magnetic block 31, which is respectively disposed on the upper back plate 114 and the lower back plate 124. The upper housing 11 and the lower housing 12 are fixed relative to each other by the attraction between the magnetic blocks 31. The magnetic blocks 31 can be fixed to the upper back plate 114 and the lower back plate 124 by means of adhesive or bolts. The magnetic blocks 31 can be disposed on the side of the upper back plate 114 facing the cavity of the upper housing 11 and the side of the lower back plate 124 facing the cavity of the lower housing 12, or they can be disposed on the outer side of the upper back plate 114 and the lower back plate 124. As a preferred embodiment, the magnetic blocks 31 are respectively inserted from the side of the upper back plate 114 facing the cavity of the upper housing 11 and the side of the lower back plate 124 facing the cavity of the lower housing 12 to the outer side of the upper back plate 114 and the outer side of the lower back plate 124, so that the magnetic blocks 31 on the upper back plate 114 and the lower back plate 124 can directly contact each other, thereby achieving a better fixing effect on the upper housing 11 and the lower housing 12.

[0034] Reference Figure 5 and Figure 7 In one specific implementation, the second fixing component includes a buckle 41 and a slot 42. The buckle 41 is disposed on the lower base plate 123, and the slot 42 is disposed on the upper base plate 113. When the upper base plate 113 and the lower base plate 123 abut, the buckle 41 engages with the slot 42, thereby fixing the upper housing 11 and the lower housing 12 relatively. In one implementation, the cross-sectional width of the buckle 41 gradually decreases in the direction away from the lower base plate 123, and the buckle 41 and the slot 42 are interference-fitted to achieve fixation. Obviously, the buckle 41 can also be disposed on the upper base plate 113, and the slot 42 can be disposed on the lower base plate 123.

[0035] A pin 115 is fixed on the upper base plate 113, and the pin 115 is connected to the circuit board inside the upper housing 11. A contact 125 is fixed on the lower base plate 123, and the contact 125 is connected to the circuit board inside the lower housing 12. The pin 115 extends from inside the upper housing 11 to the outside of the upper base plate 113, and the contact 125 extends from inside the lower housing 12 to the outside of the lower housing 12. When the upper base plate 113 and the lower base plate 123 are in contact, the pin 115 contacts the contact 125, thus connecting the circuits inside the upper housing 11 and the lower housing 12. When in the retracted state, the pin 115 and the contact 125 are disconnected, thus disconnecting the circuits between the upper housing 11 and the lower housing 12, which reduces the possibility of accidentally turning on the ear dryer when in the retracted state.

[0036] The upper base plate 113 also has a guide boss 116, on which the pin 115 is fixed. Specifically, one end of the guide boss 116 protrudes from the upper base plate 113 toward the contact point 125 and forms a guide slope 117, with the pin 115 perpendicular to the guide slope 117. The lower base plate 123 has a guide groove 126, in which the contact point 125 is located. The guide boss 116 is engaged in the guide groove 126, causing the pin 115 to abut against the contact point 125.

[0037] Reference Figure 8 and Figure 9 The lower sleeve 121 is provided with a dust plug 5, which is used to prevent water and dust from entering the charging port of the ear dryer. The dust plug 5 includes a through part 51 and a dust cover 52. The dust cover 52 is used to block the charging port of the ear dryer. The lower sleeve 121 is provided with an insertion port 53 for inserting the plug of the dust cover 52. The material of the dust cover 52 is preferably rubber. The insertion part 51 is inserted into the lower sleeve 121. The lower sleeve 121 is provided with an insertion opening 54 for the insertion part 51 to pass through. The insertion part 51 is provided with a fixing protrusion 511. After the insertion part 51 passes through the lower sleeve 121, the fixing protrusion 511 is located inside the lower sleeve 121. The cross-sectional width of the end of the fixing protrusion 51 that is away from the insertion direction of the insertion part 51 is greater than the insertion opening 54. The fixing protrusion 511 abuts against the inner wall of the lower sleeve 121 to prevent the insertion part 51 from falling out of the lower sleeve 121, thereby making the dust plug 5 relatively fixed on the lower sleeve 121.

[0038] One embodiment of the fixing protrusion 511 is that the fixing protrusion 511 extends outward from the outer periphery of the through portion 51, the cross-sectional width of the fixing protrusion 511 gradually decreases along the through direction of the through portion 51, and a guide surface is formed on the outer periphery of the fixing protrusion 511 so that the fixing protrusion 511 can pass from the outside of the lower sleeve 121 into the lower sleeve 121.

[0039] The implementation principle of a foldable ear dryer according to an embodiment of this application is as follows: the upper side plate 112 and the lower side plate 122 are hinged together. The upper side plate 112 or the lower side plate 122 rotates around the hinge axis of the upper side plate 112 and the lower side plate 122. When the upper back plate 114 and the lower back plate 124 abut together, the mouthpiece 2 is stored in the receiving cavity 13. The magnetic blocks 31 of the upper back plate 114 and the lower back plate 124 attract each other, so that the upper shell 11 and the lower shell 12 are folded and fixed, thereby realizing the storage of the ear dryer. When the upper bottom plate 113 and the lower bottom plate 123 abut together, the pin 115 contacts the contact point 125, so that the circuit of the upper shell 11 and the circuit of the lower shell 12 are connected. The buckle 41 is inserted into the slot 42 to fix the upper shell 11 and the lower shell 12 relatively, thereby switching the ear dryer to the open state.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
