Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and particularly relates to an ear canal drying and cleaning device. Background Art

[0002] The ear canals of the elderly secrete more substances, and the ear canals are often in a greasy state. If these secretions are not cleaned in time, bacteria are likely to breed in the ear canals. The elderly have relatively poor resistance, which can easily lead to ear canal inflammation. Therefore, the elderly need to regularly clean and dry their ear canals to keep them dry and clean.

[0003] With the help of an ear canal drying and cleaning device, the dirt in the user's ear canal can be effectively cleaned. The core components of traditional ear canal drying and cleaning devices include a cotton swab part and a jet part. The ear canal of the user is wiped and cleaned by the cotton swab part, and then hot air is introduced into the user's ear canal by the jet part. The hot air is used to blow-dry the user's ear canal first, so that the user's ear canal remains clean and dry.

[0004] However, when using the above device to clean and dry the user's ear canal, when the cotton swab part cleans the user's ear canal, the cotton head of the cotton swab part easily pushes the dirt attached to the inner wall of the user's ear canal deeper into the ear canal. This not only fails to thoroughly clean the user's ear canal, but also when the dirt is hidden deeper in the ear canal, it is more likely to cause inflammation of the user's inner ear canal. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and provide an ear canal drying and cleaning device that can more thoroughly clean the user's ear canal when drying and cleaning it, and prevent the user's inner ear canal from becoming inflamed due to hidden dirt.

[0006] The present invention provides an ear canal drying and cleaning device, including a jet hose, a gas supply device, and a limit plate. The gas supply device is used to supply hot air into the jet hose. The limit plate fits with the user's auricle. The limit plate is provided with a through-axis hole, and further includes:

[0007] A rotating shaft rotatably connected in the through-axis hole. The rotating shaft is provided with a first ventilation hole, and the first ventilation hole is communicated with the jet hose;

[0008] A soft plug connected to the rotating shaft. The jet hose is arranged in the soft plug. The outer wall of the soft plug is provided with a fluff layer. The fluff layer fits with the user's ear canal. The fluff layer is provided with a spiral groove coaxially arranged with the rotating shaft, and one end of the spiral groove is communicated with the atmosphere;

[0009] A ventilation pipe arranged on the side of the limit plate opposite to the soft plug. The gas supply device is communicated with the first ventilation hole through the ventilation pipe;

[0010] A pneumatic fan is provided inside the ventilation pipe. The pneumatic fan is connected to a rotating shaft. When air enters the pipe hole of the ventilation pipe, the air flow drives the pneumatic fan to rotate.

[0011] Preferably, a turntable is fixedly connected to the rotating shaft. A slider is provided on the turntable. A cam disc is provided on the limiting plate. A sliding sleeve is provided on the limiting plate. A sliding hole coaxial with the rotating shaft is provided on the sliding sleeve. A retaining ring and a spring are provided outside the rotating shaft. The retaining ring is slidably connected inside the sliding hole. The spring abuts against the retaining ring. The spring is used to apply an elastic force along the axial direction of the rotating shaft to the rotating shaft. When the rotating shaft drives the turntable to rotate, under the action of the slider, the cam disc and the spring, the rotating shaft moves back and forth along its axial direction.

[0012] Preferably, one end of the rotating shaft is provided inside the ventilation pipe. A second ventilation hole is provided near one end of the rotating shaft close to the ventilation pipe. One end of the first ventilation hole far from the jet hose is communicated with the second ventilation hole. The second ventilation hole is communicated with the pipe hole of the ventilation pipe. A sealing block is provided inside the pipe hole of the ventilation pipe. The sealing block fits against the outer wall of the rotating shaft. When the rotating shaft moves back and forth along its axial direction, the sealing block intermittently blocks the second ventilation hole.

[0013] Preferably, a connecting shaft is rotatably connected inside the pipe hole of the ventilation pipe. The connecting shaft is coaxially arranged with the rotating shaft. The pneumatic fan is fixedly connected outside the connecting shaft. A limiting sliding hole along the axial direction of the rotating shaft is provided on the rotating shaft. A limiting sliding block is provided at one end of the rotating shaft far from the jet hose. The limiting sliding block is slidably connected inside the limiting sliding hole. The limiting sliding block and the limiting sliding hole are used to limit the relative rotation of the connecting shaft with respect to the rotating shaft.

[0014] Preferably, a soft pad is provided at one end of the soft plug far from the rotating shaft. The large head end of the soft pad is connected to one end of the soft plug far from the rotating shaft. A plurality of jet ports are provided on the side wall of the tip of the soft pad. The jet ports are communicated with the jet hose. A spiral ring plate is provided on the outer wall of the soft pad. The spiral direction of the spiral ring plate is the same as that of the spiral groove. The spiral ring plate is used to guide the hot air ejected from the plurality of jet ports, so that the hot air flows from the tip of the soft pad into the spiral groove. When the spiral ring plate is rotated, the spiral ring plate can push the dirt in the user's ear canal into the spiral groove.

[0015] Preferably, the soft plug has a certain taper. The large head end of the soft plug is connected to the rotating shaft. The small head end of the soft plug is connected to the soft pad.

[0016] Preferably, a baffle is provided at the tip of the soft pad. The baffle is used to prevent the hot air ejected from the jet port from directly blowing on the eardrum.

[0017] Preferably, a pressing block is provided on the limiting plate. The pressing block has a certain elasticity. The pressing block is used to press the user's auricle against the limiting plate.

[0018] Preferably, a heat insulation layer is provided on the outer wall of the ventilation pipe.

[0019] Preferably, the soft plug is detachably connected to the rotating shaft.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: In an ear canal drying and cleaning device of the present invention, a driving part drives a rotating shaft to rotate, the rotating shaft drives a soft plug connected thereto to rotate, thereby driving a fluff layer outside the soft plug to rotate, and the fluff layer is used to clean the inner wall of the user's ear canal. Since the fluff layer is provided with spiral grooves, the dirt cleaned from the inner wall of the user's ear canal by the fluff layer will slide into the spiral grooves. By controlling the rotation direction of the soft plug, as the soft plug rotates, the spiral grooves will push the dirt out of the user's ear canal. At the same time, the hot air sprayed into the user's ear canal will be discharged from the user's ear canal through the spiral grooves, and the hot air in the spiral grooves will carry the dirt in the spiral grooves and move out of the user's ear canal, thereby cleaning the dirt in the user's ear canal completely and preventing the dirt in the user's ear canal from being pushed deeper into the ear canal, so that the user's ear canal can be cleaned more thoroughly and prevent the inner ear canal of the user from becoming inflamed due to hiding dirt.

[0021] By setting a slider, a cam disk and a spring, under the action of the cam disk, the fluff layer moves back and forth along the axial direction of the rotating shaft, so that the fluff layer not only rotates around the axis of the rotating shaft, but also moves back and forth along the axial direction of the rotating shaft. Under the action of the combined movement of the fluff layer, the cleaning effect of the fluff layer can be improved, thereby further improving the thoroughness of cleaning the user's ear canal. By setting a sealing block, under the action of the sealing block, the hot air entering the user's ear canal is an intermittent hot air flow with a relatively high pressure. Under the impact of the intermittent high-pressure hot air flow, the impact force of the hot air flow on the dirt in the spiral grooves can be improved, thereby preventing the dirt from blocking the spiral grooves, and thus ensuring the cleaning effect of the device on the user's ear canal.

"Inside", "outside", "above", "below", "far", "near", "front", "rear", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0032] Such as Figures 1-6As shown in the figure, the ear canal drying and cleaning device provided by the present invention includes a jet hose 101, a gas supply device, and a limiting plate 102. The gas supply device is used to supply hot air into the jet hose 101. The limiting plate 102 fits with the auricle of the user. The limiting plate 102 is provided with a through-axis hole, and further includes: a rotating shaft 103, a soft plug 105, a ventilation pipe 301, and a pneumatic fan 402. The rotating shaft 103 is rotatably connected in the through-axis hole. The rotating shaft 103 is provided with a first ventilation hole 104, and the first ventilation hole 104 communicates with the jet hose 101. The soft plug 105 is connected to the rotating shaft 103. The jet hose 101 is arranged inside the soft plug 105. The outer wall of the soft plug 105 is provided with a fluff layer 106. The fluff layer 106 fits with the ear canal of the user. The fluff layer 106 is provided with a spiral groove 107 coaxially arranged with the rotating shaft 103. One end of the spiral groove 107 communicates with the atmosphere. The ventilation pipe 301 is arranged on the side of the limiting plate opposite to the soft plug. The gas supply device is connected to the first ventilation hole 104 through the ventilation pipe 301. The pneumatic fan 402 is arranged inside the ventilation pipe 301. The pneumatic fan 402 is connected to the rotating shaft 103. When air enters the pipe hole of the ventilation pipe 301, the air flow drives the pneumatic fan 402 to rotate.

[0033] Now briefly describe the working principle of the above embodiment:

[0034] When the device is in use, the limiting plate 102 is fixed on the auricle of the user, and the soft plug 105 is inserted into the ear canal of the user until the limiting plate 102 fits with the auricle of the user. Then, control the gas supply device to act. The gas supply device passes hot air into the jet hose 101 through the ventilation pipe 301. The temperature of the hot air is generally maintained at 35 - 40 degrees. The jet hose 101 located inside the soft plug 105 sprays the hot air into the ear canal of the user to blow-dry the ear canal of the user. At the same time, when the gas supply device passes hot air into the pipe hole of the ventilation pipe 301, the air flow formed by the hot air drives the pneumatic fan 402 to rotate. The pneumatic fan 402 drives the rotating shaft 103 to rotate. The rotating shaft 103 drives the soft plug 105 connected to it to rotate, thereby driving the fluff layer 106 outside the soft plug 105 to rotate. The fluff layer 106 is used to clean the inner wall of the ear canal of the user. Since the fluff layer 106 is provided with a spiral groove 107, the dirt cleaned from the inner wall of the ear canal by the fluff layer 106 will slide into the spiral groove 107. By controlling the rotation direction of the soft plug 105, as the soft plug 105 rotates, the spiral groove 107 will push the dirt out of the ear canal of the user. At the same time, the hot air sprayed into the ear canal of the user will be discharged from the ear canal of the user through the spiral groove 107. The hot air in the spiral groove 107 will carry the dirt in the spiral groove 107 and move out of the ear canal of the user, thereby cleaning the dirt in the ear canal of the user. Further, by passing the medicated atomized gas into the jet hose 101 through the gas supply device of the present device, it can play an auxiliary treatment role for users with inflamed ear canals.

[0035] The ear canal drying and cleaning device of the present invention can avoid pushing the dirt in the user's ear canal deeper into the ear canal when drying and cleaning the user's ear canal, so that the user's ear canal can be cleaned more thoroughly, and prevent the inner ear canal of the user from becoming inflamed due to the hiding of dirt.

[0036] On the basis of the above embodiments, in order to enhance the cleaning effect of the fluff layer 106, and thus further enhance the thoroughness of the user's ear canal cleaning.

[0037] As shown in Figure 2 、 Figures 4-6 , a turntable 201 is fixedly connected to the rotating shaft 103, a slider 202 is arranged on the turntable 201, a cam disk 207 is arranged on the limiting plate 102, a sliding sleeve 203 is arranged on the limiting plate 102, a sliding hole 204 coaxial with the rotating shaft 103 is arranged on the sliding sleeve 203, a retaining ring 205 and a spring 206 are arranged outside the rotating shaft 103, the retaining ring 205 is slidably connected in the sliding hole 204, the spring 206 abuts against the retaining ring 205, and the spring 206 is used to apply an elastic force along the axial direction of the rotating shaft 103 to the rotating shaft 103 through the retaining ring 205. Under the action of the elastic force of the spring 206, the slider 202 abuts against the cam disk 207. When the rotating shaft 103 drives the turntable 201 to rotate, under the action of the slider 202, the cam disk 207 and the spring 206, the rotating shaft 103 moves axially back and forth along its axis.

[0038] When the rotating shaft 103 rotates, it will drive the turntable 201 to rotate, thereby driving the slider 202 on the turntable 201 to rotate around the axis of the rotating shaft 103. Due to the elastic force of the spring 206, the slider 202 slides on the cam disk 207. Under the action of the cam disk 207, the slider 202 drives the turntable 201 to move axially back and forth along the rotating shaft 103. The turntable 201 drives the rotating shaft 103 to move axially back and forth along its own axis, thereby driving the soft plug 105 to move axially back and forth along the rotating shaft 103. The soft plug 105 drives the fluff layer 106 to move axially back and forth along the rotating shaft 103, so that the fluff layer 106 not only rotates around the axis of the rotating shaft 103, but also moves axially back and forth along the rotating shaft 103. Under the action of the combined movement of the fluff layer 106, the cleaning effect of the fluff layer 106 can be enhanced, and thus the thoroughness of the user's ear canal cleaning can be further enhanced. A humidity sensor is arranged on the sliding sleeve 203, and the humidity of the air discharged from the spiral groove 107 is detected through the humidity sensor, and the humidity of the discharged air can be used to know whether the inner wall of the ear canal is dry.

[0039] As a preferred solution, as shown in Figures 2-4 and Figure 6As shown in the figure, one end of the rotating shaft 103 is arranged in the ventilation pipe 301. A second ventilation hole 302 is provided at one end of the rotating shaft 103 close to the ventilation pipe 301. One end of the first ventilation hole 104 far from the jet hose 101 is communicated with the second ventilation hole 302, and the second ventilation hole 302 is communicated with the hole of the ventilation pipe 301. A sealing block 303 is arranged in the hole of the ventilation pipe 301, and the sealing block 303 fits against the outer wall of the rotating shaft 103. When the rotating shaft 103 reciprocates along its axis, the sealing block 303 intermittently blocks the second ventilation hole 302. By arranging the cam disk 207, under the action of the cam disk 207, the rotating shaft 103 reciprocates along its axis, so that the second ventilation hole 302 reciprocates relative to the sealing block 303, and thus the second ventilation hole 302 is intermittently blocked by the sealing block 303. When the second ventilation hole 302 is blocked by the sealing block 303, with the continuous intake of air in the hole of the ventilation pipe 301, since the second ventilation hole 302 is blocked, the air pressure in the hole of the ventilation pipe 301 continuously rises. When the rotating shaft 103 rotates to the position where the sealing block 303 no longer blocks the second ventilation hole 302, the second ventilation hole 302 is communicated with the hole of the ventilation pipe 301, and the hot air with increased pressure in the hole of the ventilation pipe 301 enters the first ventilation hole 104 in the rotating shaft 103 through the second ventilation hole 302, and then is sprayed into the ear canal of the user through the jet hose 101. Under the action of the sealing block 303, the hot air entering the ear canal of the user is an intermittent hot air flow with relatively high pressure. Under the impact of the intermittent high-pressure hot air flow, the impact force of the hot air flow on the dirt in the spiral groove 107 can be enhanced, so as to prevent the dirt from blocking the spiral groove 107, and thus ensure the cleaning effect of the device on the ear canal of the user.

[0040] As a preferred solution, as Figure 2 、 Figure 3 and Figure 6As shown in the figure, a connecting shaft 401 is rotatably connected inside the pipe hole of the ventilation pipe 301. The connecting shaft 401 is coaxially arranged with the rotating shaft 103. The pneumatic fan 402 is fixedly connected to the outside of the connecting shaft 401. A limiting sliding hole 404 along the axial direction of the rotating shaft 103 is provided on the rotating shaft 103. A limiting sliding block 403 is provided at one end of the rotating shaft 103 away from the jet hose 101. The limiting sliding block 403 is slidably connected inside the limiting sliding hole 404. The limiting sliding block 403 and the limiting sliding hole 404 are used to limit the relative rotation of the connecting shaft 401 with respect to the rotating shaft 103. When the pneumatic fan 402 rotates, the pneumatic fan 402 drives the connecting shaft 401 to rotate. Under the limiting action of the limiting sliding block 403 and the limiting sliding groove, the rotating shaft 103 can be driven to rotate, thereby driving the soft plug 105 and the fluff layer 106 to rotate. When the rotating shaft 103 reciprocates along its own axis, the rotating shaft 103 drives the limiting sliding block 403 to slide inside the limiting sliding groove, so as to ensure that the connecting shaft 401 can continuously drive the rotating shaft 103 to rotate. Driving the rotating shaft 103 to rotate by using the hot air supplied by the air supply device can drive the soft plug 105 and the fluff layer 106 to rotate without using electric components, thus avoiding the use of special electric components, which can not only improve the reliability of the device, but also prevent the safety hazards caused by the leakage of electric components.

[0041] As a preferred solution, as Figure 2 shown in the figure, a rotation speed sensor 5 is provided inside the pipe hole of the ventilation pipe 301. The rotation speed sensor 5 is used to detect the real-time rotation speed of the pneumatic fan 402. The rotation speed sensor 5 is electrically connected to a controller. A predetermined rotation speed is preset in the controller. The predetermined rotation speed is determined according to the age of the user. The older the user is, the greater the predetermined rotation speed is. The controller is electrically connected to the air supply device. The controller controls the air flow speed of the hot air supplied by the air supply device according to the real-time rotation speed and the predetermined rotation speed, so that the real-time rotation speed of the pneumatic fan 402 is equal to the predetermined rotation speed. The eardrums in the ear canals of younger users are more fragile than those of older users. When younger users use it, the jet speed of the jet hose 101 should be appropriately reduced. Since the rotation speed of the pneumatic fan 402 is proportional to the air flow speed into the pipe hole of the ventilation pipe 301, by setting the rotation speed sensor 5 and using the rotation speed sensor 5 to detect the real-time rotation speed of the fan, the air flow velocity in the pipe hole of the ventilation pipe 301 can be known, and thus the air flow speed of the hot air ejected from the jet hose 101 can be known. Therefore, the predetermined rotation speed of the pneumatic fan 402 can be set according to the age of the user. The controller controls the air flow speed of the hot air supplied by the air supply device according to the real-time rotation speed and the predetermined rotation speed, so that the real-time rotation speed of the pneumatic fan 402 is equal to the predetermined rotation speed, so that the air flow speed ejected from the jet hose 101 is suitable for users of different ages.

[0042] As a preferred solution, as Figure 1 andFigure 2 As shown, one end of the soft plug 105 away from the rotating shaft 103 is provided with a soft pad 601. The soft pad 601 has a certain taper. The large end of the soft pad 601 is connected to the end of the soft plug 105 away from the rotating shaft 103. The side wall of the tip of the soft pad 601 is provided with a plurality of air jet ports 602. The air jet ports 602 are communicated with the air jet hose 101. The outer wall of the soft pad 601 is provided with a spiral ring plate 603. The spiral direction of the spiral ring plate 603 is the same as that of the spiral groove 107. The spiral ring plate 603 is used to guide the hot air ejected from the plurality of air jet ports 602, so that the hot air flows from the tip of the soft pad 601 into the spiral groove 107. When the spiral ring plate 603 rotates, the spiral ring plate 603 can push the dirt in the user's ear canal into the spiral groove 107. When the rotating shaft 103 drives the soft plug 105 to rotate, it will drive the soft pad 601 to rotate in the same direction, thereby driving the spiral ring plate 603 to rotate. And the soft pad 601 has a certain taper, and the soft pad 601 can be inserted into a deeper position of the user's ear canal. The rotating spiral ring plate 603 can clean the dirt deeper in the user's ear canal. Since the spiral direction of the spiral ring plate 603 is the same as that of the spiral groove 107, the dirt cleaned by the spiral ring plate 603 can be pushed into the spiral groove 107. Under the transportation of the spiral groove 107, it can be discharged from the user's ear canal, thereby improving the thoroughness of cleaning the user's ear canal. The tip of the soft pad 601 is provided with a camera 10. The camera 10 is used to photograph the inside of the user's ear canal. The camera 10 is connected to a display via Bluetooth. The display is used to display the picture taken by the camera 10. When the user operates the device, the camera 10 takes a real-time picture of the user's ear canal, then transmits the taken picture via Bluetooth, and then displays the picture of the patient's ear canal on the display, and operates the actions of the entire device, so as to facilitate the control of the entire device.

[0043] As a preferred solution, as Figure 1 and Figure 2 shown, wherein, the soft plug 105 has a certain taper. The large end of the soft plug 105 is connected to the rotating shaft 103. The small end of the soft plug 105 is connected to the soft pad 601. By setting the soft plug 105 to have a certain taper, it can adapt to the ear canals of most users. The soft plug 105 together with the soft pad 601 can be more easily inserted into the user's ear canal, and it can prevent the soft pad 601 from contacting the inner wall of the user's ear canal prematurely, thereby preventing the soft pad 601 from pushing the dirt in the user's ear canal deeper into the ear canal.

[0044] As a preferred solution, as Figure 1 and Figure 2 ​As shown, a pressing block 8 is provided on the limiting plate 102. The pressing block 8 has a certain elasticity and is used to press the auricle of the user against the limiting plate 102. By providing the pressing block 8, the auricle of the user is pressed against the limiting plate 102 by the pressing block 8, so as to ensure the accuracy of the insertion depth of the soft plug 105, so as to ensure that the fluff layer 106 can fit against the inner wall of the user's ear canal and ensure the cleaning effect of the device.

[0045] As a preferred solution, as Figure 1 and Figure 2 shown, a baffle 9 is provided at the tip of the soft pad 601. The baffle 9 is used to prevent the hot air ejected from the air jet port 602 from directly blowing on the eardrum. By providing the baffle 9, the hot air ejected from the air jet port 602 is blocked by the baffle 9, so as to prevent the hot air ejected from the air jet port 602 from directly blowing on the eardrum and prevent the hot air from causing harm to the eardrum of the user.

[0046] As a preferred solution, as Figure 2 shown, a heat insulation layer 7 is provided on the outer wall of the ventilation pipe 301. By providing the heat insulation layer 7 on the outer wall of the ventilation pipe 301, the hot air in the ventilation pipe 301 can be heat-insulated, so as to prevent the heat of the hot air in the ventilation pipe 301 from being dissipated, and thus ensure the drying effect of the device.

[0047] As a preferred solution, as Figure 2 shown, the soft plug 105 is detachably connected to the rotating shaft 103. By setting the soft plug 105 and the rotating shaft 103 to be detachably connected, it is convenient to replace the soft plug 105 and the fluff layer 106 when the fluff layer 106 on the soft plug 105 is excessively worn.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
