Technical Field

[0001] The utility model relates to the technical field of formaldehyde removal, in particular to a formaldehyde removal and dust removal device. Background Art

[0002] Various decoration materials and furniture used in interior decoration often bring harmful substances such as formaldehyde, benzene and other volatile organic compounds. The excess of these substances will seriously affect our health and interfere with our daily life.

[0003] Especially for furniture, because a large amount of adhesives are often needed in the process of board manufacturing, the toxic and harmful substances brought in by the adhesives are hidden inside the boards. The later release of harmful substances such as formaldehyde is also a long and slow process.

[0004] At present, activated carbon with porous surface is mostly used for adsorption. In order to accelerate the adsorption of formaldehyde, a fan is usually used to drive the air flow. The flowing air passes through the activated carbon particles to achieve the adsorption of formaldehyde. However, the flowing air will drive the dust flow, which can easily cause the micropores on the surface of the activated carbon particles to be blocked, affecting the adsorption of formaldehyde by the activated carbon. Dust also fills the gaps between the activated carbon particles, affecting air flow. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a formaldehyde removal and dust removal device, which solves the problem that the flowing air will drive the dust to flow, which may easily cause the micropores on the surface of the activated carbon particles to be blocked, affecting the adsorption of formaldehyde by the activated carbon, and the dust fills the gaps between the activated carbon particles, affecting the air flow.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a formaldehyde removal and dust removal device, comprising:

[0007] Suction sleeve, suction pipe and suction fan;

[0008] The suction sleeve is hollow and has two open ends. The suction port of the suction fan is connected to one end of the suction pipe, and the other end of the suction pipe is connected to one end of the suction sleeve.

[0009] A protective cover is arranged inside the suction sleeve, and a dustproof filter plate and an activated carbon adsorption bag are arranged inside the protective cover.

[0010] Preferably, support sleeves are sleeved on the outer walls of the suction sleeve and the suction fan, and hangers are provided on the upper sides of the two support sleeves.

[0011] Preferably, the hanger includes a column connected to the upper sides of the two support sleeves, and a suspension beam is provided on the upper sides of the two columns.

[0012] Preferably, an external thread is provided on the outer wall of the protective cover, and an internal thread ring matching the external thread is provided inside the suction sleeve.

[0013] Preferably, a limiting convex ring is provided on the left side of the outer wall of the protective cover.

[0014] Preferably, an inner support frame is provided at the left end opening of the suction sleeve, and a rotating handle is provided in the middle of the inner support frame.

[0015] Preferably, a retaining frame is provided on the right side inside the suction sleeve, and the right end of the protective cover is supported on the retaining frame.

[0016] The utility model provides a formaldehyde removal and dust removal device, which has at least the following beneficial effects compared with the prior art:

[0017] When the air flows, the front side is initially filtered through the dust filter plate, and the filtered air enters the activated carbon adsorption bag, which adsorbs formaldehyde from the filtered air. This ensures the long-term use of the activated carbon adsorption bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] See also Figure 1-2 , the utility model provides a technical solution: a formaldehyde removal and dust removal device, comprising: a suction sleeve 1, a suction pipe 2 and a suction fan 3;

[0023] Among them, the suction sleeve 1 is a hollow tube with openings at both ends, the suction port of the suction fan 3 is connected to one end of the suction pipe 2, the other end of the suction pipe 2 is connected to one end of the suction sleeve 1, and a protective cover 9 is arranged inside the suction sleeve 1, and a dust filter plate 14 and an activated carbon adsorption bag 15 are arranged inside the protective cover 9.

[0024] Analysis of the above content: When in use, the suction fan 3 is powered on and starts working. The suction fan 3 sucks air, and the air flows from left to right. The air is filtered through the dust filter plate 14, so that the dust in the air is filtered out. The filtered air is adsorbed by the activated carbon adsorption bag 15 to remove formaldehyde. The principle of the activated carbon adsorption bag 15 to purify the air is to rely on the developed pore structure and surface area of ​​the carbon itself, which can contact the surrounding air to a large extent and passively adsorb some pollutants into its own pores. Therefore, the larger the surface of the activated carbon and the more developed the pore structure, the stronger the adsorption capacity. Example

[0025] See also Figure 1-2 The utility model provides a technical solution based on the first embodiment: the outer walls of the suction sleeve 1 and the suction fan 3 are sleeved with a support sleeve 4, and a hanger is arranged on the upper side of the two support sleeves 4.
