Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde purification, and more specifically, to a purification device suitable for formaldehyde. Background Art

[0002] Formaldehyde is commonly found in some house decorations. It is extremely harmful to the human body. Before moving in, a formaldehyde purification device is needed to remove the formaldehyde.

[0003] In this regard, China has applied for patent number: CN202222977501.8, which discloses a formaldehyde purification device for indoor use. In view of the fact that most of the existing formaldehyde purification devices for indoor use are not convenient for rapid disassembly and assembly of the formaldehyde purification board, which results in a relatively time-consuming replacement of the formaldehyde purification board, the following scheme is proposed, which includes a shell, a suction fan and a formaldehyde purification board. The suction fan is fixedly mounted on the bottom inner wall of the shell, and a placement groove is provided on the bottom inner wall of the shell. The outer side of the formaldehyde purification board is movably connected to the placement groove. A connecting plate is fixedly mounted on the top of the formaldehyde purification board, and a baffle is fixedly mounted on the top of the connecting plate. Positioning plates are fixedly mounted on both sides of the bottom of the baffle. The utility model has a reasonable structural design. Through the abutment and cooperation between the abutment plate and the baffle, the formaldehyde purification board can be quickly installed and disassembled, thereby facilitating the replacement of a new formaldehyde purification board, and the operation is convenient and the reliability is high.

[0004] The purification device can quickly disassemble and assemble the formaldehyde purification plate through the cooperation of the abutment plate and the baffle plate. However, before the formaldehyde purification plate is installed, the abutment plate and the baffle plate still need to be operated, and it cannot be guaranteed that the formaldehyde purification plate fits the inner wall of the shell, so that some formaldehyde in the air enters the shell and is not discharged by the formaldehyde purification plate, which will affect the purification effect.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a purification device suitable for formaldehyde. Utility Model Content
