Description
Technical Field

[0002] Currently, pet drying boxes are used to dry pets' fur. For example, the Chinese invention patent application publication number CN118923556A, "A Pet Fur Care Dryer," describes a pet drying box with an internal cavity for holding the pet. A circulating fan is located on the top of the cavity to supply air into it. The circulating fan includes a cross-flow impeller and a fan cover. The cross-flow impeller is located inside the fan cover, which is situated inside the pet drying box. The lower end of the fan cover connects to the upper part of the cavity. Because the pet moves around inside the cavity, and the circulating fan causes the air inside to circulate, dirt (including pet hair) easily accumulates on the cross-flow impeller and the inner wall of the cavity. Currently, the method involves opening the corresponding door for the pet to enter and exit, then cleaning the cavity by hand with a cloth, and opening the fan door to wipe the cross-flow impeller. However, this cleaning method is labor-intensive and does not improve the cleaning effect. Summary of the Invention

Detailed Implementation
[0018] The present invention will now be further described with reference to the accompanying drawings.
[0019] The spray cleaning system of this utility model, such as Figures 1 to 3 As shown, it includes a chamber spray head 1 located on the upper part of the chamber 99 and an impeller cleaning nozzle 2 correspondingly located on the outside of the impeller 97. To allow the impeller cleaning nozzle 2 to directly spray the impeller 97, the impeller cleaning nozzle 2 extends into the corresponding fan cover 98. Furthermore, since the impeller 97 is a cross-flow impeller, as... Figure 4 As shown, three impeller cleaning nozzles 2 are distributed on the main water spray pipe 20, and the main water spray pipe 20 extends approximately parallel to the axis of the impeller 97. That is, each of the two impellers 97 has a corresponding main water spray pipe 20, which is located outside the fan cover 98. The spray cleaning system of this utility model also includes a water pump 3, a steam generator 4, a water tank 5, an ozone generator 6, and a Venturi mixer 9. The input end of the water pump 3 is connected to the water tank 5, the output end of the water pump 3 is connected to the liquid input end of the Venturi mixer 9, the liquid output end of the Venturi mixer 9 is connected to the input end of the steam generator 4, the air intake end of the Venturi mixer 9 is connected to the ozone generator 6, and the output end of the steam generator 4 is connected to the chamber spray head 1 and the impeller cleaning nozzles 2. It also includes a controller 100, which controls the water pump 3, the steam generator 4, and the ozone generator 6. The ozone generator 6 and the Venturi mixer 9 are existing technologies.
[0020] The working principle of the spray cleaning system of this utility model is briefly explained below: Figure 1 As shown, the pet drying box has a cavity 99 for accommodating the pet. Two sets of circulating fan assemblies are located on the upper side of the cavity 99. Each circulating fan assembly includes a fan cover 98 and an impeller 97. The lower end of the fan cover 98 connects to the upper part of the cavity 99. Since the two impellers 97 are respectively equipped with water spray pipes 20, the two water spray pipes 20 can be connected to the output end of the steam generator 4 using a T-fitting. Figure 3As shown, when the pet drying box needs cleaning, the controller 100 controls the water pump 3 to operate. The water pump 3 draws water from the water tank 5 and outputs the water to the Venturi mixer 9. The ozone generator 6 generates ozone, which is drawn into the suction end of the Venturi mixer 9 and then mixed into the water. The water then flows to the steam generator 4, where the electric heater heats the water to form a mixture of steam and liquid water. This mixture is then sprayed through the spray nozzle 1 in the box cavity. Inside the chamber 99, a high-temperature spray cleaning and ozone disinfection effect is achieved. The mixture of steam and liquid water is also sprayed onto the impeller 97 through the impeller cleaning nozzle 2, washing away pet hair from the blades of the impeller 97. The water then flows down into the chamber 99 through the lower end of the fan cover 98, further cleaning and disinfecting the impeller 97. During this process, the circulating fan assembly can be powered on, causing the impeller 97 to rotate and splashing water onto it, enhancing the rinsing effect. During the cleaning process, the controller 100 can also deactivate the electric heater of the steam generator 4, thus providing a cold water cleaning effect for the chamber 99 and impeller 97. Alternatively, the controller 100 can control the steam generator 4 to operate at a lower power to avoid generating high-temperature steam, providing a warm water cleaning effect for the chamber 99 and impeller 97. For example, the steam generator 4 can raise the water temperature to approximately 50°C to 70°C. This invention features a chamber spray head 1 for cleaning the chamber 99 and an impeller cleaning spray head 2 for cleaning the impeller 97. This eliminates the need for manual cleaning of the chamber and impeller, and facilitates more effective cleaning of the interior of the pet drying box.
[0021] Furthermore, such as Figure 2 and Figure 3As shown, the spray cleaning system of this utility model also includes at least two cleaning auxiliary material tanks 7. Each cleaning auxiliary material tank 7 is equipped with an auxiliary material pump 71. The input end of the auxiliary material pump 71 is connected to the corresponding cleaning auxiliary material tank 7, and the output end of the auxiliary material pump 71 is connected to the input end of the steam generator 4. The control system controls the auxiliary material pump 71. The auxiliary material pump 71 can be a peristaltic pump. Thus, the cleaning auxiliary material can be injected into the water flow through the corresponding auxiliary material pump 71. Then, the cleaning auxiliary material reaches the steam generator 4, and the water mixed with the cleaning auxiliary material is sprayed onto the impeller 97 and the chamber 99. For example, the cleaning auxiliary material can be disinfectant or formaldehyde removal agent, etc. For formaldehyde removal agent, refer to the Chinese invention patent application publication number CN108771961B "A biological enzyme formaldehyde removal agent and its application". Steam generator 4 can heat the mixture of disinfectant and water to 50°C to 70°C, and then spray the water containing disinfectant onto the chamber 99 and impeller 97, thereby achieving a warm water disinfection effect on the chamber 99 and impeller 97. Of course, at this time, controller 100 can also control the electric heater of steam generator 4 to not work, or control steam generator 4 to work at a higher power to generate steam. When the control system controls the auxiliary pump 71 corresponding to the cleaning auxiliary tank 7 containing disinfectant to not work, the control system controls the auxiliary pump 71 corresponding to the cleaning auxiliary tank 7 containing formaldehyde removal agent to work, thereby achieving a formaldehyde removal effect on the chamber 99 and impeller 97. Figure 2 and Figure 3 The example illustrates a scenario where there are three cleaning aid tanks 7, and correspondingly, three aid pumps 71. One cleaning aid tank 7 can hold disinfectant, the second can hold formaldehyde remover, and the third can serve as a backup, for example, holding perfume. Through the flexible control of the steam generator 4 and aid pumps 71 by the controller 100, the interior of the pet drying box can be cleaned and purified in multiple modes.
[0022] Furthermore, such as Figure 2 and Figure 3 As shown, the Venturi mixer 9 is connected in parallel with a bypass pipe 92. Since the water flow required for the Venturi mixer 9 to absorb ozone is relatively small, the water flow capacity of the Venturi mixer 9 is relatively poor. In order to meet the flow requirements, the bypass pipe 92 is set up so that the water flow output by the water pump 3 can pass through the bypass pipe 92 directly to the steam generator 4 at a relatively large flow rate, thereby meeting the water flow required for the normal operation of the chamber spray head 1 and the impeller cleaning spray head 2. At the same time, the water flow output by the water pump 3 passes through the Venturi mixer 9 at a relatively small flow rate.
[0023] Furthermore, such as Figure 2 and Figure 3As shown, the spray cleaning system of the pet drying box of this utility model also includes a four-way fitting 1001. The bypass pipe 92, the liquid output end of the Venturi mixer 9, the output end of the auxiliary pump 71, and the input end of the steam generator 4 are respectively connected to the four-way fitting 1001. More specifically, the four-way fitting 1001 is a cross-shaped four-way fitting, including a first interface, a second interface, a third interface, and a fourth interface. One end of the bypass pipe 92 is connected to the output end of the water pump 3, and the corresponding other end of the bypass pipe 92 is connected to the first interface. The liquid output end of the Venturi mixer 9 is connected to the second interface, and the input end of the steam generator 4 is connected to the third interface. The output ends of each auxiliary pump 71 are connected to the aforementioned fourth interface via a Y-shaped four-way fitting. By setting the four-way fitting 1001, it is convenient for the input end of the steam generator 4 to receive tap water, ozone, and cleaning aids. Figure 3 As shown, a check valve 13 is provided between the first interface and the bypass pipe 92, a check valve 13 is provided between the second interface and the liquid output end of the Venturi mixer 9, and a check valve 13 is provided between the fourth interface and the aforementioned Y-type four-way valve.
[0024] Furthermore, such as Figure 3 As shown, the spray cleaning system of the pet drying box of this utility model also includes a spray head solenoid valve 11 and a spray head solenoid valve 21. The output end of the steam generator 4 is connected to the box cavity spray head 1 through the spray head solenoid valve 11, and the output end of the steam generator 4 is connected to the impeller cleaning spray head 2 through the spray head solenoid valve 21. The control system controls the connection between the spray head solenoid valve 21 and the spray head solenoid valve 11. Thus, according to actual needs, the control system can only open the spray head solenoid valve 11 and close the spray head solenoid valve 21 to clean only the box cavity 99. Similarly, the control system can only open the spray head solenoid valve 21 and close the spray head solenoid valve 11, which is conducive to flexible cleaning of the pet drying box.
[0025] Furthermore, the chamber spray head 1 is configured as a rotating spray head, so the chamber spray head 1 can rotate during the spraying process, which is beneficial for the chamber spray head 1 to spray the inner wall of the chamber 99 over a larger area. The rotating spray head is a prior art. For example, see Chinese invention application publication number CN117244710A "Rotating spray head and cleaning device equipped with the rotating spray head" and Chinese utility model patent publication number CN218921196U "A durable rotating spray head".
[0026] Furthermore, such as Figure 2As shown, the water tank 5 is equipped with a float valve 52 for connecting to the tap water pipe. The float valve 52 is installed on the wall of the water tank 5. The inlet end of the float valve 52 is connected to the tap water pipe, and the outlet end of the float valve 52 is located inside the water tank 5. When tap water is injected into the water tank 5, as the water level in the water tank 5 rises, the water in the water tank 5 causes the float ball of the float valve 52 to float up, thereby causing the float valve 52 to close automatically. When the water pump 3 works, it causes the water level in the water tank 5 to drop, and the float ball of the float valve 52 to descend, causing the float valve 52 to open automatically, thereby realizing the automatic replenishment of water in the water tank 5.
