[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0034] Addressing the current problems of incomplete pet ear cleaning, complex operation, and pet discomfort, this utility model provides a preferred embodiment of a pet ear cleaning device, for example... Figures 1-6 As shown: A pet ear cleaning device includes a liquid storage handle portion 21 and a main structure portion 22. The liquid storage handle portion 21 has a connecting thread on the inner wall of its top end, which matches the thread at the bottom end of the main structure portion 22. By rotating the connection, the liquid storage handle portion 21 and the main structure portion 22 are tightly fixed.

[0035] The main structural part 22 adopts a circular + cylindrical design. A circular groove is provided on the front of the circular portion of the main structural part 22, and a controller 23 is sealed inside the groove. The controller 23 contains a microprocessor, and its surface has a display screen 231 electrically connected to the microprocessor and touch buttons. The touch buttons include a power switch button 232, a washing mode selection button 233, and a drying mode selection button 234. Earmuffs 24 are installed on one side of the circular portion of the main structural part 22. The earmuffs 24 are made of skin-friendly silicone, and double ear cups are installed in the center of the earmuffs. The double-channel connector 25 is fitted with an mounting block 26 on its exterior. Miniature red light sources 29 electrically connected to the drying mode selection button 234 are evenly installed on the mounting block 26. The mounting block 26 has a built-in double-cavity flow channel that communicates with the double-channel connector 25 to form independent cleaning and drying channels. The intersection of the cleaning and drying channels is connected to the soft silicone nozzle body structure 28 threadedly connected to the center of the mounting block 26. One-way valves 27 are installed inside the cleaning and drying channels to ensure unidirectional flow of liquid and gas and prevent backflow.

[0036] It should be noted that the design of the earcups 24 takes into full consideration the structure of the pet's ears, ensuring a close fit without damaging the ear canal. The miniature red light source 29 provides a sterilization function during the drying process, using red light in the 650-nanometer band. The specific power can be adjusted according to the size of the pet's ear canal, such as between 0.5W and 1W, to meet the needs of different pets' ear canals. Since this is an existing publicly available technology, it will not be described in detail here.

[0037] A filter 31 is installed at the bottom of the cylindrical part of the main structure 22. The filter 31 has a built-in flow channel and a filter element cotton is installed in the flow channel, which can effectively filter impurities in the cleaning fluid. A liquid pipe 32 is connected to the bottom of the filter 27. A micro hydraulic valve 33 electrically connected to the microprocessor is installed on the liquid pipe 32. The micro hydraulic valve 33 controls the flow rate and pressure of the cleaning fluid through the cleaning mode selection button 233.

[0038] The main structure 22 is equipped with a cleaning pipeline 34 and a drying pipeline 46. One end of the cleaning pipeline 34 is connected to a one-way valve 27, and the other end extends to the cleaning channel inlet on the double-hole connector 25.

[0039] The cylindrical part of the main structure 22 has a hollow interior design. An air inlet slot is provided on one side of the exterior, and a filter screen 41 is installed inside the air inlet slot. A filter element 42 is provided on the inner surface of the filter screen 41. A miniature fan 43 is also provided inside the cylindrical part. The fan blades are driven by a motor to generate directional airflow. The air is purified by the filter element 42 and enters the interior. An air duct 45 is also provided inside the cylindrical part. One end of the air duct 45 is connected to the air inlet slot, and a heating element 44 is built into the air duct 45. The heating element 44 is electrically connected to the drying mode selection button 234. The airflow is heated by the heating element 44. The other end of the air duct 45 is connected to the drying pipe 46 through the heating cylinder structure. The drying pipe 46 extends to the drying channel inlet of the double-hole connector 25.

[0040] It should be noted that the heating element 44 is a heating wire. The heating wire is made of high-resistance alloy material and consists of two or more layers (such as a main heating wire and a voltage-reducing heating wire). The operation of different layers of heating wire is controlled by a selector switch. By combining different layers of heating wire, multiple temperature settings such as low temperature, medium temperature, and high temperature can be achieved. This is a publicly available technology, including its specific installation layout and working principle. The related linkage principles involving temperature controllers, overheat protection systems, etc., will not be elaborated here. Example

[0041] Please see Figures 1-6 Furthermore, based on Embodiment 1, the following is further obtained: the soft silicone nozzle main body structure 28 specifically includes a soft silicone nozzle main body threaded section 281, which is tightly connected to the central thread of the mounting block 26 to achieve a stable seal and prevent liquid leakage. It also includes a soft silicone nozzle channel 282 located inside, with a liquid flow nozzle at the head end and a graphene oxide film 283, which effectively prevents gas from accidentally entering the nozzle. This film is formed by stacking graphene oxide sheets and contains oxygen-containing functional groups such as hydroxyl and epoxy groups on its surface. Functional groups provide steric hindrance, resulting in a larger interlayer spacing and reserved gaps, forming a graphene capillary network. This allows water molecules to slide through with low friction, while the interaction between oxygen-containing functional groups and intercalated water hinders the passage of gas molecules. The soft silicone nozzle channel 282 has equidistantly spaced gas nozzles 284 on its inner circumference, each with a hydrophobic microporous membrane 285. This effectively prevents liquid from accidentally entering the nozzle. The membrane has low surface tension, making it difficult for liquid to form a continuous liquid film on its surface, thus preventing liquid permeation. Simultaneously, gas molecules, due to their small size and low surface tension, can pass through the tiny pores in the membrane.

[0042] The heating cylinder structure specifically includes a heating cylinder body 471, a heat-conducting cavity 472, and a heating coil 473. A heat insulation cavity is provided between the heating cylinder body 471 and the heat-conducting cavity 472. The heating coil 473 is surrounded on the outside of the heat-conducting cavity. The heating coil 473 is electrically connected to the drying mode selection button 234. The heat generated by the heating coil 473 is transferred to the heat-conducting cavity 472, thereby ensuring the preheating of the temperature of the heat-conducting cavity 472. The outer wall of the heat insulation cavity is made of a ceramic material with a low thermal conductivity to effectively isolate heat leakage, and the inner wall of the heat insulation cavity is made of a nanomaterial with a high thermal conductivity to ensure that the heat is concentrated and transferred to the heat-conducting cavity.

[0043] When using this product to clean a pet's ears, first fill the liquid reservoir handle 21 with liquid, then slowly insert the soft silicone nozzle body 28 into the pet's ear canal (the pet's ear can be tilted to facilitate better drainage of wastewater). Turn on the power switch 232 and click the cleaning mode selection button 233. There are five adjustable modes:

[0044] Level 1: Sensitive Mode;

[0045] Level 2: Gentle mode;

[0046] 3rd gear: Standard mode;

[0047] 4th gear: Power mode;

[0048] Level 5: Deep Cleaning Mode;

[0049] Subsequently, the liquid enters the filter 27 through the liquid pipe 32 and the micro hydraulic valve 33 for filtration, then enters the cleaning channel inlet on the dual-channel connector 25 through the cleaning pipe 34, and finally is evenly sprayed out from the liquid flow nozzle of the soft silicone nozzle channel 282 to gently clean the pet's ear canal.

[0050] After cleaning, the dirt produced falls from the pet's ear canal into the ear cover 24, which can then be cleaned and disinfected, as well as the nozzle is removed for cleaning and disinfection.

[0051] Finally, you can click the drying mode selection button 234, which has three adjustable modes:

[0052] Level 1: Gentle drying; Level 2: Standard drying; Level 3: Rapid drying; Simultaneously, the miniature red light source 29, heating element 44, miniature fan 43, and heating coil 473 all start up. The miniature fan 43 rotates to generate directional airflow, which enters the interior after being purified by the filter 42. After being heated by the heating element 44 in the air duct 45, the air enters the heat conduction chamber 472 and is heated by the heating coil 473, forming a warm and dry airflow channel in the drying pipe 46. The air then enters the drying channel inlet of the dual-channel connector 25 and is finally evenly sprayed out from the gas nozzle 284 of the soft silicone nozzle channel 282, acting evenly on the pet's ear canal to effectively remove residual moisture. At the same time, the red light emitted by the miniature red light source 29 helps to reduce inflammation and kill bacteria, further protecting the health of the pet's ear canal.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
