Technical Field
The utility model relates to a photocatalyst formaldehyde scavenger belongs to environmental protection technology field.
Background
Formaldehyde is an essential binder component in many board manufacturing processes. In the home decoration process and in a period of time after decoration, formaldehyde in the board can be gradually released and dispersed in indoor air, so that the formaldehyde is harmful to the health of people. Therefore, many times, people adopt many measures to avoid the harm of formaldehyde, for example, people open a window to ventilate after finishing decoration by using decorative materials containing little formaldehyde as much as possible, and live in after a few months. However, these methods do not allow people to avoid formaldehyde damage, and sometimes cause economic loss due to the failure to live in time. How to remove the formaldehyde to cause the harm to people becomes a great problem to be solved urgently.
The currently common method is to remove formaldehyde hazards by an activated carbon adsorption method. The active carbon is internationally recognized as a drug-absorbing hand, two to three dishes are placed in each house, and indoor peculiar smell can be basically eliminated within 72 hours. The disadvantages are that: when activated carbon absorbs a certain amount of formaldehyde, the adsorption function of the activated carbon is not available, and the activated carbon cannot continuously and permanently absorb formaldehyde.
The' 200410077942.6 patent discloses a formaldehyde scavenger which contains expensive materials such as vitamin C, is expensive to manufacture, and is ineffective when a certain amount of formaldehyde reacts with the formaldehyde scavenger, and does not continuously and permanently exert its formaldehyde scavenging effect.
The patent with application number 03100568.3 discloses a formaldehyde scavenger and a manufacturing method thereof, the preparation process is complex, multiple steps of filtering, extracting, washing, reduced pressure evaporation, crystallization, drying and the like are required, the price is high, and the effect is common.
Although the types of methods for removing formaldehyde are more, the above methods have the problems of single structure, incapability of ensuring the removal effect, complex structure, high cost, high operation requirement and the like, and an ideal and perfect system tool for removing formaldehyde is not formed, so the removal effect is not good. Therefore, there is a need for a device that can be continuously used and permanently remove formaldehyde, which has a simple working principle, reliable performance and low cost.

The utility model adopts the technical proposal that:
a photocatalyst formaldehyde remover is characterized by comprising a shell, a honeycomb photocatalyst filter screen, a fan, an ultraviolet lamp and a power line, wherein the honeycomb photocatalyst filter screen, the fan and the ultraviolet lamp are all arranged in the shell, and the honeycomb photocatalyst filter screen divides the interior of the shell into two spaces; a fan and an air inlet are arranged in one space, and an air outlet is arranged in the other space; the ultraviolet lamp is arranged in any space or both spaces.
The fan is arranged in one space and provided with an air inlet, and the ultraviolet lamp is arranged in the other space and provided with an air outlet.
The fan is arranged at the bottom in the shell, and an air inlet is formed in a bottom plate of the shell.
The ultraviolet lamp is composed of a plurality of LED ultraviolet luminotrons and a circuit board, the ultraviolet lamp is arranged at the top in the shell, and the air outlet is arranged on the side surface of the shell.
The power supply voltage of the fan and the ultraviolet lamp is 220V commercial power.
The power supply voltage of the fan and the ultraviolet lamp is 12V or 5V direct current.
The utility model has the advantages that:
1. the utility model discloses photocatalyst formaldehyde cleaner utilizes photocatalyst to degrade pollutants such as formaldehyde, benzene, toluene, xylol, ammonia, TVOC to decompose toxin and innocent treatment that bacterium or fungi released.
2. Irradiating the honeycomb photocatalyst filter screen by using an ultraviolet lamp to ensure that the photocatalyst keeps activity for a long time; the formaldehyde removing efficiency is improved by adopting the fan, the air inlet and the air outlet.
3. The utility model discloses photocatalyst formaldehyde duster simple structure, small, convenient to use, good reliability, power consumption are few, do not have consumptive material with low costs, safety, durable and the effect is obvious, can be used to the indoor formaldehyde of building and in the auttombilism room and other harmful gas's cleaing away.
Drawings
Fig. 1 is a schematic structural diagram of the photocatalyst formaldehyde remover of the present invention.
Fig. 2 is an appearance schematic diagram of the photocatalyst formaldehyde remover of the present invention.
In the figure: 1. the device comprises a shell, 2, a honeycomb photocatalyst filter screen, 3, a fan, 4, an ultraviolet lamp, 5, a power line, 6, a space, 7, another space, 8, an air inlet, 9, an air outlet, 10, wind, 11 and ground feet.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 and 2 illustrate an embodiment of the present invention. In the figure, a photocatalyst formaldehyde cleaner comprises a shell 1, a honeycomb photocatalyst filter screen 2, a fan 3, an ultraviolet lamp 4 and a power line 5. The honeycomb photocatalyst filter screen 2, the fan 3 and the ultraviolet lamp 4 are all fixed in the shell 1, and the space in the shell is divided into two spaces by the honeycomb photocatalyst filter screen 2; one space 6 is provided with a fan 3 and an air inlet 8, and the other space 7 is provided with an air outlet 9.
In this embodiment, a fan 3 and an air inlet 8 are provided on the bottom plate of the housing 1 in one space 6. An ultraviolet lamp 4 is arranged in the other space 7 and is provided with an air outlet 9. The ultraviolet lamp 4 is composed of a plurality of LED ultraviolet luminotrons and a circuit board, the ultraviolet lamp 4 is arranged at the top part in the shell 1, and the air outlet 9 is arranged at the side surface of the shell 1 in the other space 7. The supply voltage for the fan 3 and the uv lamp 4 is 220V mains.
The design effectively avoids the adverse effect of ultraviolet light on users, and has simple structure and small volume.
The utility model discloses photocatalyst formaldehyde cleaner's theory of operation describes as follows: the power cord 5 is turned on, the fan 3 is rotated, and the ultraviolet lamp 4 is turned on. The higher feet 11 make the shell 1 have a certain height space with the ground, and the fan 3 rotates to suck the formaldehyde-containing air outside the bottom plate of the shell 1 into a space 6 from the air inlet 8. Known from common general knowledge: the flowing air forms wind 10, and along with the continuous rotation of the fan 3, the air containing formaldehyde in one space 6 continuously flows through the honeycomb photocatalyst filter screen 2 and enters the other space 7. Since the photocatalyst material on the honeycomb photocatalyst filter screen 2 can effectively degrade formaldehyde, a part of formaldehyde in the air containing formaldehyde flowing through the honeycomb photocatalyst filter screen 2 is degraded, and the concentration of formaldehyde in the air entering the other space 7 is reduced. With the fan 3 rotating continuously, air entering the other space 7 will flow out of the outlet 9. Because the ultraviolet lamp irradiates the honeycomb photocatalyst filter screen, the photocatalyst keeps activity for a long time.
It is thus clear that as long as keep the power supply, the utility model discloses photocatalyst formaldehyde cleaner can be with the air that contains certain concentration formaldehyde from air intake 8 by the air that inhales, degrades into the air that contains lower concentration formaldehyde from air outlet 9 outflow, and this process will continuously go on, and the formaldehyde concentration in the room air will constantly reduce, reaches the effect of cleaing away formaldehyde.
