Description

Technical Field

[0001] This utility model relates to the field of ear cleaning equipment technology, and in particular to an ear dryer for ear cleaning. Background Technology

[0002] Currently, with the development of the ear-cleaning industry, especially visual ear-cleaning technology, the demand for ear canal cleaning and care is increasing. In daily life, water entering the ear canal after swimming or bathing, or after rinsing with liquid during ear cleaning, can easily breed bacteria and cause inflammatory problems such as otitis media, especially for people with oily ears. Traditional methods often rely on wiping with cotton swabs, which not only has limited effectiveness but also carries the risk of damaging the ear canal skin or pushing in earwax.

[0003] Most existing home ear dryers on the market are handheld designs with built-in motors that operate close to the ear, generating noticeable noise and resulting in a poor user experience. Furthermore, there is a lack of professional-grade equipment to meet the ear cleaning service industry's demands for efficiency, quiet operation, and multi-functionality. Therefore, there is an urgent need for a professional-grade, low-noise, and multi-functional ear canal care device to address these technical pain points. Summary of the Invention

[0004] The main purpose of this utility model is to overcome the shortcomings of the existing technology and provide an ear dryer for ear cleaning.

[0005] The technical solution adopted by this utility model to achieve its technical purpose is: an ear dryer for ear cleaning, including a housing, a drying air tube, a handheld pen body, an ear canal tube, a power supply, etc. The chassis is equipped with an air pump power switch, a circuit control board, and a drying air pump. A heat-conducting pipe is installed inside the pen body. One end of the heat-conducting pipe is connected to a drying air pipe, and the other end is connected to an ear canal tube. One end of both the ear canal tube and the drying air pipe is fixed inside the outer shell of the pen body. One end of the drying air pipe is connected to the heat-conducting pipe, and the other end is connected to the drying air pump. The drying air pipe is connected to the air outlet of the drying air pump through an air pipe connector on the chassis.

[0006] A heating element is attached to the outside of the heat pipe, and a heat insulation layer is wrapped around the heating element. The outer shell of the pen body is located outside the heat insulation layer. The heating element is connected to the power switch of the air pump via a power cord on the drying air pipe. The power cord can be fixedly installed inside or outside the drying air pipe.

[0007] The power supply is fixed inside the chassis to provide electricity. The gas flow rate is adjusted by regulating the speed of the drying air pump, thereby regulating the temperature of the air inside the pen body. The air pump power switch also controls the start and stop of the heating element. When the air pump power switch is turned on, the heating element also starts heating. The gas delivered by the drying air pump passes through the drying air pipe and heat conduction pipe, and is heated by the heating element before being output through the ear canal tube. Therefore, the gas flow rate can be adjusted by regulating the speed of the drying air pump, thereby controlling the temperature of the air inside the pen body.

[0008] The chassis is equipped with a heat setting button, which is connected to a drying air pump via a circuit control board. The heat setting button has two settings, positive and negative. The air pump power switch controls the start and stop of the drying air pump. When the air pump power switch is turned on, the drying air pump runs, simultaneously energizing the heating element to heat the heat pipe. This heat is then transferred to the air flowing inside the pipe, creating hot air that enters the ear canal and dries the moisture inside. The air flow rate is adjusted by regulating the speed of the drying air pump using the heat setting button, thereby controlling the temperature entering the ear canal. The setting display screen shows the setting.

[0009] Preferably, the heat pipe is a bent copper tube or a spiral tube, which can improve the heat conduction efficiency and enhance the heating effect. The spiral or bent structure can increase the heat exchange area.

[0010] Preferably, the ear canal is covered with a soft tube, which can protect the ear skin and can provide heat insulation or be used for single purposes.

[0011] Preferably, the ear canal tube is made of stainless steel and has multiple small ventilation holes on the side of the head end to allow air to pass through. Stainless steel is corrosion resistant, and the ventilation holes ensure even airflow distribution, avoiding discomfort caused by direct airflow.

[0012] Preferably, a main power switch is also fixedly installed on the chassis. The main power switch is connected to the power circuit inside the chassis, and the main power switch allows for convenient one-button operation.

[0013] Preferably, the pen body is equipped with a pen body power switch, which can independently control the heating element to start and stop. The user can control the heating element to start and stop by hand, making the operation more convenient.

[0014] Preferably, an electric fan is fixedly installed on one side of the chassis to provide ventilation and heat dissipation, thereby preventing overheating of internal circuit components, drying air pumps, and other parts, and extending the equipment's lifespan.

[0015] Preferably, the chassis is equipped with a flushing air pump, the flushing air pump is connected to a flushing air pipe, and the flushing air pipe is connected to a negative pressure water spray device; The water spraying device includes a water bottle, a rinsing air tube connected to the water bottle, and a water suction tube inside the water bottle, which is sealed and connected to the spraying tube. When air pressure enters the water bottle, it compresses the water inside, causing the water to enter the spraying tube and rinse the ear canal. The air pressure drives the water flow to clean the ear canal, thus achieving the ear canal rinsing function. The length of the rinsing tube is the same as the length of the drying air tube for ease of operation.

[0016] Preferably, the water spray pipe is equipped with a pneumatic control valve. When the pneumatic control valve is opened, the water spray pipe sprays water. When the pneumatic control valve is released, the water spray pipe stops rinsing. The pneumatic control valve can control the start and stop of water flow and the amount of water, so as to achieve precise rinsing and avoid waste or over-rinsing.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This ear dryer effectively reduces noise: by placing the drying air pump inside the casing and connecting it to the handheld pen body via a long air tube, the motor in the drying air pump is kept away from the ear, which not only significantly reduces the noise during operation and improves the user experience, but also reduces the size and weight of the handheld pen body, making it easier to hold and operate and observe the ear canal.

[0018] This ear dryer for ear cleaning features intelligent temperature control and airflow adjustment: the air pump speed can be adjusted via the heat setting button and circuit control board to achieve precise control of the air temperature and airflow, meeting the ear canal care needs of different users.

[0019] This ear dryer for ear cleaning is compact and easy to operate: the handheld pen body is lightweight, with a built-in heating element and heat insulation layer, and an external power switch. Users can operate it by hand to flexibly control the heating function and improve the convenience of operation.

[0020] This ear dryer for ear cleaning is multifunctional: it can be equipped with a flushing air pump and a negative pressure water spray device to achieve integrated operation of ear canal flushing and drying, improve nursing efficiency, and avoid cross-infection.

[0021] This ear-drying device for ear cleaning offers significantly improved safety and durability: the ear canal tube can be fitted with a disposable flexible tube, and the built-in cooling fan in the chassis effectively extends the device's lifespan while ensuring hygiene and safety during use.

[0022] This ear dryer is suitable for a wide range of scenarios: it is not only suitable for professional ear cleaning places, but also for home care, especially for patients with otitis media, people with oily ears, and for daily ear care needs after water gets into the ear canal.

A heat-conducting pipe 6 is installed inside the pen body 2. A heating element 7 is attached to the heat-conducting pipe 6, and a heat insulation layer 8 is wrapped around the heating element. The outer shell of the pen body 2 is outside the heat insulation layer. One end of the heat-conducting pipe 6 is connected to a drying air pipe 3, and the other end is connected to an ear canal tube 1. Both the ear canal tube 1 and one end of the drying air pipe 3 are fixed inside the outer shell of the pen body 2.

The heating element 7 is connected to the air pump power switch 10 through a power cord 11 on the drying air pipe 3. The power cord 11 can be located inside or outside the drying air pipe.

[0031] The heat pipe 6 can be a bent copper tube or a spiral tube to improve heat conduction efficiency and enhance heating effect. The spiral or bent structure can increase the heat exchange area.

[0032] Furthermore, in this embodiment, a gear display screen 12 and a heat level button 13 are also included. The heat level button 13 is connected to the drying air pump 5 through the circuit control board 16. The heat level button 13 is set with two gears, positive and negative. The air pump power switch 10 controls the start and stop of the drying air pump 5. When the air pump power switch 10 is turned on, the drying air pump 5 runs. The air flow rate is adjusted by adjusting the speed of the drying air pump 5 through the heat level button 13. The gear display screen 12 is used to display the gear.

[0033] Furthermore, in this embodiment, a main power switch 17 is also fixedly installed on the chassis 4. The main power switch 17 is connected to the internal power circuit of the chassis 4, and the main power switch 17 facilitates one-button operation.

[0034] Furthermore, in this embodiment, an electric fan is fixedly installed on one side of the chassis 4 to provide ventilation and facilitate heat dissipation, thereby preventing overheating of internal circuit components, drying air pumps, and other parts, and extending the equipment's lifespan.

[0035] The ear canal tube 1 is covered with a soft tube 14, which can protect the ear skin or facilitate disposable use. The ear canal tube 1 is made of stainless steel and has multiple small ventilation holes on the side of the head end to allow air to pass through.

[0038] Based on the above embodiments, the ear dryer for ear cleaning has a flushing air pump in the housing 4, which is connected to a flushing air pipe, and the flushing air pipe is connected to a negative pressure water spray device. The water spray device includes a water bottle, which is connected to the flushing air pipe. A water suction pipe is installed inside the water bottle and is sealed to the water spray pipe. When air pressure enters the water bottle, it compresses the water inside the bottle, and the water enters the water spray pipe to flush the ear canal. Thus, the water flow driven by air pressure can clean the ear canal and realize the ear canal flushing function.

[0039] The spray pipe is equipped with a pneumatic control valve. When the pneumatic control valve is opened, the spray pipe sprays water. When the pneumatic control valve is released, the spray pipe stops rinsing. The pneumatic control valve can control the start and stop of the water flow, achieving precise rinsing and avoiding waste or over-rinsing.

[0040] It should be noted that none of the above components are shown in the figure. Their related structures / components can be designed with reference to existing technologies, and will not be described in detail here.

[0041] The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0042] The working principle and specific usage process of this ear dryer are as follows: After turning on the main power switch 17, the drying air pump 5 and heating element 7 are started through the air pump power switch 10. The air pump generates airflow, which is delivered to the heat-conducting pipe 6 inside the handheld pen body 2 through the drying air pipe 3. The airflow is heated as it flows through the heat-conducting pipe 6 heated by the heating element 7, and finally the hot air is blown into the ear canal through the ear canal tube 1 for drying. The user can adjust the air pump speed to control the air volume and heat through the heat level button 13. The level information is displayed in real time on the level display screen 12. If the rinsing function is required, the rinsing air pump is started. The air pressure enters the water bottle through the rinsing air pipe, forcing the water to flow through the water suction pipe and the water spray pipe. The ear canal can be rinsed in a pulse-like manner by operating the air pressure control valve on the water spray pipe. This device integrates drying and rinsing functions. By designing the noise source air pump 5 away from the ear in a chassis-style design, the comfort and professionalism of use are significantly improved.
