[0011] Beneficial effects
[0012] This invention employs an internal circulation design. When the pet needs drying after washing, the fan is activated. The fan draws air from the pet washing chamber through the air inlet pipe. The drawn-in air enters the heater area and is heated to a preset temperature. The heated air is then blown back into the pet washing chamber through the air outlet pipe to dry the pet. A temperature sensor inside the pet washing chamber continuously monitors the internal temperature. The thermostat adjusts the working state of the heating element in real time according to the set temperature target to ensure that the blown air maintains a constant temperature. The entire process forms a closed loop, with air constantly being drawn in, heated, and blown out, thus ensuring that the ambient temperature inside the pet washing chamber remains constant. Furthermore, the air inlet filter prevents hair or other debris from being drawn into the fan, affecting the lifespan of the equipment or causing secondary pollution. The fan speed is also adjustable via a driver to accommodate pets of different sizes and hair lengths. Since the blowing process generates moisture, a dehumidifier can be used to improve drying efficiency and comfort. Attached Figure Description
