Example

[0038] Please see Figure 1 and Figure 2 This embodiment provides a pet hair drying device 10, which can be used in a drying system to dry pets after washing and grooming.

[0039] The pet hair drying device 10 provided in this embodiment includes a nozzle body 100, a nozzle cover 200, and a heater 300. The nozzle body 100 has a connector end 100a and a mounting end 100b. The connector end 100a is used to connect to the hot air pipe of the hot air supply subsystem 400 and the return air pipe of the suction subsystem 500. The nozzle body 100 has a hot air supply channel 100c and a hot air return channel 100d inside.

[0040] The nozzle cover 200 is disposed at the mounting end 100b of the nozzle body 100. The nozzle cover 200 is provided with a plurality of hot air holes 210 that connect to the hot air supply channel 100c and a return air hole 220 that connects to the hot air return channel 100d. The plurality of hot air holes 210 are arranged around the return air hole 220.

[0041] Furthermore, the area of ​​the return air hole 220 is larger than that of the hot air hole 210, so that the return air hole 220 can accommodate more hair during drying, and can also promptly remove shed hair and impurities.

[0042] In this embodiment, a number of hot air holes 210 are distributed on the outer edge of the nozzle cover 200, and the return air hole 220 is located in the middle of the nozzle cover 200, realizing a three-dimensional air duct and improving drying efficiency.

[0043] Optionally, the hot air hole 210 can be a round hole, a square hole, or an elongated arc-shaped hole, or other irregular holes.

[0044] When the pet hair drying device 10 provided in this embodiment is connected to the drying system for drying operations, hot air is sprayed from the hot air supply channel 100c to the hot air hole 210 of the nozzle cover 200 for drying. At the same time, hot air return channel 100d draws in air, and the pet's hair and the surrounding hot air are drawn into the return air hole 220, thereby forming a vortex airflow, so that the hair is dried again in the return air hole 220. The heater 300 is set in the hot air return channel 100d and close to the return air hole 220, thereby providing the temperature required for re-drying, thereby improving drying efficiency and greatly shortening drying time.

[0045] Please see Figure 1 and Figure 2 The nozzle body 100 includes an outer shell 110 and an inner shell 120. The inner shell 120 is located inside the outer shell 110. One end of the outer shell 110 is the mounting end 100b. The cavity formed between the inner shell 120 and the outer shell 110 is a hot air supply channel 100c, and the inner cavity of the inner shell 120 is a hot air return channel 100d. The ends of the inner shell 120 and the outer shell 110 furthest from the mounting end 100b are connector ends 100a. In this embodiment, connector end 100a is provided with a hot air interface 101 and a suction interface 102. The hot air interface 101 is disposed inside the suction interface 102. Thus, the cross-sectional area of ​​the suction interface 102 is larger than the cross-sectional area of ​​the hot air interface 101, effectively preventing the suction interface 102 from becoming clogged.

[0046] Understandably, the hot air inlet 101 is used to connect to an external hot air duct, and the air intake inlet 102 is used to connect to a return air duct. In this way, the hot air duct and the return air duct can be integrated into a sleeve structure using a pipe-in-pipe method, and the diameter of the return air duct should be designed to be larger to prevent the intake of fallen hair from being blocked.

[0047] The heater 300 is positioned within the hot air return air duct 100d and close to the return air hole 220. This ensures that the heat generated by the heater 300 can be drawn closer to the pet's fur through the return air hole 220, improving the drying effect and shortening the drying time.

[0048] In some embodiments, the heater 300 is selected as a heating wire.

[0049] Optionally, the heating wire is arranged around the return air vent 220 to ensure that the heat radiated to the center of the return air vent 220 is uniform.

[0050] In other embodiments, the heater 300 may be a heating element disposed on the inner wall of the hot air return air duct 100d.

[0051] Optionally, multiple heating elements can be provided, and the heating elements are arranged around the return air vent 220 to ensure that the heat radiated to the center of the return air vent 220 is uniform.

[0052] In some embodiments, a first temperature sensor (not shown) is also provided within the hot air return air duct 100d. Along the airflow direction within the hot air return air duct 100d, the first temperature sensor is arranged downstream of the heater 300 to detect the temperature within the hot air return air duct 100d in real time. Thus, the drying system can control the temperature of the heater 300 based on the temperature feedback from the first temperature sensor to ensure temperature stability within the return air vent 220. Optionally, the temperature of the return air vent 220 can be controlled between 35 and 47°C.

[0053] The nozzle cover 200 is recessed inward on the side opposite to the nozzle body 100 to form a concave cavity 230, and the return air hole 220 is disposed at the bottom of the concave cavity 230. The concave cavity 230 can accommodate more hair, improving drying efficiency; and the depth of the concave cavity 230 allows the hair to spread out inside, resulting in faster moisture evaporation and further improving drying efficiency.

[0054] In some embodiments, the nozzle cover 200 is trumpet-shaped. The inner diameter of the concave cavity 230 gradually decreases from the surface of the nozzle cover 200 to the return air hole 220.

[0055] In some embodiments, the nozzle cover 200 is detachably connected to the mounting end 100b. The detachable connection can be achieved through snap-fit, plug-in, or threaded connection, among other methods. It should be understood that the above are merely illustrative examples and are not intended to limit the scope of protection of this application.

[0056] Please refer to the following: Figure 3 and Figure 4 Furthermore, this embodiment also provides a drying system, including a hot air supply subsystem 400, a suction subsystem 500, and a pet hair drying device 10 provided above. The connector end 100a of the nozzle body 100 in the pet hair drying device 10 is connected to the hot air pipe of the hot air supply subsystem 400 and the return air pipe of the suction subsystem 500.

[0057] The aforementioned hot air supply subsystem 400 includes a drying execution module 410 and an air supply module 420, which are sequentially connected via hot air ducts. The drying execution module 410 heats the airflow supplied by the second air supply module 420 to the pet hair drying device 10, causing the pet hair drying device 10 to spray hot air for drying pet hair.

[0058] The drying execution module 410 is an electric heating device with a hot air outlet, which is connected to the nozzle body 100 via a hot air pipe.

[0059] Furthermore, the air supply module 420 includes an air supply filter 424, an air supply device 421, a hot air flow regulating valve 423, and a hot air flow sensor 422, which are connected sequentially through an air supply duct. The hot air flow sensor 422 is connected to the air inlet of the drying execution module 410. A second temperature sensor 411 is also provided at the air outlet of the drying execution module 410. The second temperature sensor 411 is used to detect the air temperature in the air supply duct, the hot air flow sensor 422 is used to detect the hot air flow in the air supply duct, and the hot air flow regulating valve 423 can adjust the flow rate of the air supply duct. Optionally, the hot air flow regulating valve 423 is a solenoid valve.

[0060] In some embodiments, a manual regulating valve may also be provided between the air supply duct between the air supply device 421 and the drying execution module 410.

[0061] The aforementioned suction subsystem 500 includes a suction fan 510, a water collection tank 520, and a hair collector 530. The suction fan 510, the water collection tank 520, the hair collector 530, and the nozzle body 100 are connected in sequence through a suction pipe.

[0062] When drying a pet, the suction fan 510 can be started simultaneously. The suction fan 510 creates negative pressure in the suction pipe and draws in water (moisture) and hair through the return air hole 220. The drawn water and hair will first pass through the hair collector 530 to separate the hair from the water, and the water will further enter the water collection tank 520 for collection.

[0063] The water collection tank 520 can be equipped with a sewage level sensor 540 to determine the sewage level in the water collection tank 520. After the level reaches a preset height, drainage will be initiated to prevent water from overflowing. The drain outlet of the water collection tank 520 can be equipped with a controllable drain valve 590, which can be selected as an electromagnetic drain valve or an electric valve.

[0064] The suction duct between the suction fan 510 and the water collection tank 520 is also equipped with a suction flow sensor 550, a manual suction regulating valve 580, a suction solenoid regulating valve 560, and a suction filter 570. The suction flow sensor 550 is used to detect the gas flow signal in the suction duct in real time to determine the blockage status of the suction filter 570. The suction solenoid regulating valve 560 can adjust the suction flow rate.

[0065] Alternatively, the suction fan 510 can be an air pump.

[0066] The drying system provided in this embodiment simultaneously activates the hot air supply subsystem 400 and the suction subsystem 500 during the drying operation. The hot air supply subsystem 400 generates hot air and sprays it through the hot air delivery channel 100c in the nozzle body 100 to the hot air hole 210 of the nozzle cover 200 for drying. At the same time, the suction subsystem 500 generates negative pressure in the hot air return channel 100d and draws air through the return air hole 220. The pet's fur and the surrounding hot air are drawn into the return air hole 220, thereby forming a vortex airflow, which allows the fur to be dried again in the return air hole 220. The heater 300 is set in the hot air return channel 100d and close to the return air hole 220, thereby providing the temperature required for re-drying, thereby improving drying efficiency and greatly shortening drying time.
