Description

Technical Field

[0001] The utility model belongs to the technical field of formaldehyde treatment agent spraying, and particularly relates to a formaldehyde treatment agent spraying device with an automatic feeding structure. Background Technique

[0002] The technical background of the formaldehyde treatment agent spraying device stems from the concern for indoor air quality and living environment. It usually consists of a spraying device and a medicine tank for storing the agent. This device sprays the agent into the air and uses the agent to carry out chemical reactions or adsorption on formaldehyde, thereby reducing the concentration of formaldehyde in the room. However, there are some problems with the existing formaldehyde treatment agent spraying devices. One of them is that the medicine tank is large in volume and heavy in weight, and a connecting transmission pipeline is required. Due to the large volume and heavy weight of the medicine tank, it may be difficult to carry the medicine tank, especially when operating in a narrow space. The external medicine tank needs to be replenished regularly, but due to the limitation of the medicine tank position and the need for a connecting transmission pipeline, the feeding process may be more cumbersome, increasing the maintenance cost and working difficulty. Content of the Utility Model

[0005] Preferably, the large medicine tank backpack supplies materials to the small medicine tank assembly through a separated feeding method, so as to realize that the large medicine tank backpack supplies high-pressure spray materials to the small medicine tank assembly and the spray gun assembly sprays materials externally. After disconnecting the small medicine tank assembly from the large medicine tank backpack, only relying on the small medicine tank to provide an independent feeding source for the device, it is convenient for the function of independent feeding in the construction scenario where the large medicine tank backpack is not easy to carry in a narrow spraying area, and solves the problems of the existing formaldehyde treatment agent spraying device, because its external medicine tank is large in volume and heavy in weight and requires a connecting transmission pipeline, it is difficult to carry the formaldehyde removal medicine tank in a narrow space and inconvenient to replenish materials.

[0006] As a preference, a sealing nut is arranged outside the lower end of the small medicine tank, and the sealing nut is threadedly locked and sealed with the output end of the small medicine tank and the input end of the spray gun assembly.

[0007] Preferably, a material pipe interface is provided on the upper end surface of the small material tank, and the outer wall of the material pipe interface is threadedly and sealingly connected to the output pipeline of the large material tank backpack.

[0008] Preferably, a high-pressure check valve is provided inside the material pipe interface, and the spraying inside the small material tank can only enter the inside of the small material tank from the outside. After the material pipe interface is connected to the large material tank backpack, due to the high pressure inside the large material tank backpack, the spraying passes through the high-pressure check valve along the pipeline and enters the small material tank for replenishing and feeding. When the material pipe interface is disconnected from the large material tank backpack, the high-pressure check valve is closed and sealed, so that the spraying inside the small material tank directly sprays out from the material channel for spraying operation, further improving the convenience of replenishing materials after the connection between the small material tank and the large material tank backpack.

[0009] Preferably, the spray gun assembly includes a spray gun, a trigger, a material channel, and a spring material channel plug; a material channel is provided inside the spray gun assembly, and the material channel is communicated with the output end of the small material tank.

[0010] Preferably, a spring material channel plug is provided inside the material channel, and the spring material channel plug moves along the spring piston of the material channel. One end of the spring material channel plug blocks the channel between the material channel and the output end of the small material tank. A trigger is provided at the center of the outside of the spray gun, and the trigger is rotationally and bucklingly connected to the spring material channel plug. Through the separate feeding method of replenishing materials from the large material tank backpack to the small material tank assembly, high-pressure spraying is supplied from the large material tank backpack to the small material tank assembly and then sprayed out by the spray gun. After disconnecting the small material tank assembly from the large material tank backpack, only relying on the small material tank to provide an independent feeding source for the device, it is convenient for independent replenishment in the construction scenario where the large material tank backpack is not easy to carry in a narrow spraying area.

A separate feeding method of using a large material tank backpack to supply materials to a small material tank assembly is adopted to realize that the large material tank backpack supplies high-pressure spraying materials to the small material tank assembly for the spray gun to spray externally. After disconnecting the small material tank assembly from the large material tank backpack, only relying on the small material tank to provide an independent feeding source for the device, which facilitates the independent feeding function in the construction scenario where the large material tank backpack is not easy to carry in a narrow spraying area; it solves the problems of the existing formaldehyde treatment agent spraying device that the external medicine tank is large in volume and heavy in weight and requires connecting transmission pipelines, resulting in difficulties in handling the formaldehyde removal medicine tank in narrow spaces and inconvenient feeding.

Through the setting of the high-pressure check valve, after the material pipe interface is connected to the large material tank backpack, due to the high pressure in the large material tank backpack, the spraying material passes through the high-pressure check valve along the pipeline and enters the small material tank for feeding. When the material pipe interface is disconnected from the large material tank backpack, the high-pressure check valve is closed and sealed, so that the spraying material inside the small material tank directly sprays out from the material channel for spraying operation, further improving the feeding convenience after the connection between the small material tank and the large material tank backpack.

[0015] 3.
