[0002] A pet cabinet is a multifunctional cabinet used to provide rest and entertainment for pets. Depending on the type of pet, the type of pet cabinet varies. When raising a pet, the pet can be placed directly in the cabinet, which can provide a comfortable living environment for the pet.

[0003] However, the existing pet cabinets have relatively simple functions and cannot provide a suitable constant temperature environment for pets, which makes it easy for pets to develop various diseases after being in the pet cabinet for a long time. At the same time, for pets that are prone to produce strong odors, the odors are easily emitted to the environment outside the pet cabinet, affecting the surrounding environment.

[0004] Therefore, a negative pressure device is needed to prevent the discharge of odor in the pet cabinet. At the same time, a heating device is needed to provide appropriate hot air to the cabinet and adjust the temperature in the cabinet. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic structural diagram of a negative pressure heating device according to an embodiment of the utility model.

[0015] In the figure, 1 is a shell, 2 is a negative pressure unit, 3 is a heating module, 4 is a hot air delivery unit, and 5 is a mounting portion. DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0017] Example:

[0018] A negative pressure heating device for a pet cabinet is installed on the pet cabinet to achieve negative pressure and hot air delivery inside the pet cabinet, such as Figure 1 As shown, it includes a shell 1 and a negative pressure unit 2 installed on the shell. A heating module 3 and a hot air delivery unit 4 are arranged inside the shell. The negative pressure unit discharges the air in the pet cabinet, the heating module heats the air entering the shell from the outside, and the hot air delivery unit delivers the heated air into the pet cabinet.

[0019] The shell is provided with a mounting portion 5, and the mounting portion is provided with a threaded through hole. The thread passes through the threaded through hole to install the shell on the pet cabinet, so that the device and the pet cabinet are tightly combined and installed. The threaded installation is tighter to prevent air leakage from the gap. The side of the shell facing the pet cabinet is provided with an air outlet, and the side of the shell away from the pet cabinet is provided with an air inlet. The upper end of the shell is installed with a negative pressure unit. The shape of the entire shell is a rectangular structure, which has a certain space capacity, and the working unit can be installed inside. The air inlet is provided with a valve. When the valve is opened, external air enters the shell and flows through the heating module. When the valve is closed, external air cannot enter the shell.

[0020] The negative pressure unit includes a first axial flow fan and a second axial flow fan. The two groups of axial flow fans have different working powers, thereby realizing different degrees of air extraction modes. For example, only the first axial flow fan is turned on, and its air extraction speed is level a, so that the air pressure in the pet cabinet is 0.8 times the atmospheric pressure within the rated time. Only the second axial flow fan is turned on, and its air extraction speed is level b, so that the air pressure in the pet cabinet is 0.5 times the atmospheric pressure within the rated time. The first axial flow fan and the second axial flow fan are turned on at the same time, and their air extraction speed is level c, so that the air pressure in the pet cabinet is 0.2 times the atmospheric pressure within the rated time. Therefore, different degrees of negative pressure states can be achieved.

[0021] The heating module uses a PTC heating resistor. The hot air delivery unit is a fan, which is fixedly installed inside the shell. The PTC heating resistor can stably heat the external air entering from the air inlet. At the same time, the fan works to blow the heated gas remaining in the shell into the pet cabinet.

[0022] It should be noted that the negative pressure unit and heating module of the utility model are two different working modes, which work alone and do not run at the same time. When the negative pressure unit works, the valve is closed, and the air cannot enter the shell. The heating module and the fan do not work. After the negative pressure is extracted from the pet cabinet, the pet cabinet is in a normal state. When the temperature of the pet cabinet needs to be adjusted, the odor in the pet cabinet is first processed and then the valve is opened. The negative pressure unit does not work. If the heating module does not work and only the fan works, the air entering the pet cabinet is at normal temperature. If the heating module is turned on at the same time, the external air is heated, and hot air enters the pet cabinet.

[0023] In another embodiment of the utility model, in order to better coordinate the operation of the negative pressure unit, the heating module and the hot air delivery unit, a control unit is provided. The control unit is used to control the operation of the negative pressure unit, the heating module and the hot air delivery unit. The operation of different units can be performed in a conventional manner through timing control or command control, so that the pet cabinet can provide a suitable environment for the pet.

[0024] In another embodiment of the utility model, the operation of the negative pressure unit, the heating module and the hot air delivery unit can also be controlled by setting a mechanical switch. By installing the mechanical switch on the shell, different mechanical switches correspond to different working units.

[0025] The utility model forms a negative pressure state in the pet cabinet by arranging a negative pressure unit, so that the odor in the pet cabinet cannot be emitted into the external environment. After the odor in the pet cabinet is cleaned, hot air can be delivered to the pet cabinet by arranging a heating module and a hot air delivery unit. When the heating module is not turned on, normal temperature air can be delivered to the pet cabinet, which can play a role in regulating the temperature of the pet cabinet and provide a suitable temperature environment for the pet.

[0026] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
