Referring to fig. 1 to 7, the present invention provides a cabinet with photocatalyst air purification, including: the cabinet body 1, the photocatalyst module 2 and the fan 3;

an air inlet is formed in the bottom of the cabinet body 1, and an air outlet is formed in the side face of the cabinet body; the photocatalyst module 2 and the fan 3 are sequentially arranged in the cabinet body 1 along the wind direction.

Therefore, the cabinet has the function of photocatalyst air purification, and compared with the traditional bathroom cabinet, the cabinet combines the air purification function into the bathroom cabinet on the premise of keeping the traditional storage function. Compared with other air purifiers, the air purification function is more suitable for being used in a bathroom humid environment, the HEPA filter screen and the active carbon lose the purification function and breed bacteria in the humid environment, and a new pollution source is formed. And photocatalyst filter screen and metal filter screen combine to can effectively avoid breeding of bacterium to the realization can wash, and no consumptive material is fit for long-term the use.

In this embodiment, the photocatalyst module 2 includes at least three layers of photocatalyst aluminum honeycomb panels 21 stacked one on another, and a UV ultraviolet lamp 22 is disposed between two adjacent layers of photocatalyst aluminum honeycomb panels 21. The aluminum honeycomb network is used as a base material, the surface of the aluminum honeycomb network is covered with a photocatalyst material with a photocatalytic function represented by titanium dioxide, and substances with strong oxidizing property (such as hydroxyl radicals, oxygen and the like) are generated under the irradiation of specific ultraviolet rays and can be used for decomposing the molecular structure of harmful components, inhibiting the growth of bacteria and the activity of viruses, thereby realizing the function of purifying air. In this embodiment, three layers of photocatalyst aluminum honeycomb panels 21 are taken as an example, and in actual use, the number of photocatalyst aluminum honeycomb panels 21 can be arbitrarily increased or decreased according to the specific design and the needs of the use scene, which belongs to the simple replacement of this embodiment.

In this embodiment, in order to increase the air filtering effect, a primary filter 4 is further disposed between the air inlet and the photocatalyst module 2, and is used for filtering large particles in the air. Such as hair, dander, suspended dust, etc.

In order to place the filtering assembly in the cabinet body 1, a first partition plate 11 and a second partition plate 12 are arranged in the cabinet body 1; the first partition plate 11 is used for dividing the space in the cabinet body 1 into a first space for installing the photocatalyst module 2 and the fan 3 along the width direction; the second partition board 12 is disposed at a side of the first partition board 11 and extends along a length direction of the cabinet 1 to form a second space above the first space.

In order to install the photocatalytic aluminum honeycomb panel 21, a plurality of installation grooves 111 are provided at intervals along the height direction on the side surface of the first partition plate 11, and one end of the photocatalytic aluminum honeycomb panel 21 is placed in the installation grooves 111.

In order to further increase the air purification effect, a negative ion generator 5 is arranged in the second space, and the negative ion generator 5 is arranged behind the air outlet surface of the fan 3 along the wind direction. The negative ion generator 5 is a device for producing negative ions, and the negatively charged negative ions and the smoke dust floating in the air and having positive charges are subjected to electrode neutralization to be naturally deposited, thereby purifying the air.

The structure can only realize manual air purification, that is, a user opens the air purification assembly when the air purification is needed. In order to realize that the air purification assembly can be automatically opened when the air quality is poor, the second space is also provided with an air detection module 6 for detecting the concentration of PM2.5, the concentration of volatile organic compounds and the concentration of ammonia in the air. Therefore, detected air quality data can be sent to the main controller, and the main controller automatically opens the air purification assembly when the air quality is poor. As a simple alternative to this embodiment, the air detection module 6 may also be mounted on the bottom plate of the cabinet 1.

In order to allow the air detection module 6 in the second space to contact the external air, an abdicating opening 112 is formed in the first partition plate 11, and the air detection module 6 contacts the external air through the abdicating opening 112. If the air detection module 6 is installed on the bottom plate of the cabinet 1, a corresponding abdication opening 112 is also required to be formed on the bottom plate.

In this embodiment, air purification needs to be opened when someone is present, and for this reason, still be provided with human microwave radar inductive switch 7 in the second space. The signal output end of the human body microwave radar inductive switch 7 and the signal output end of the air detection module 6 are respectively connected to the signal input end of the main controller, and the signal output end of the main controller is connected to the photocatalyst module 2, the fan 3 and the negative ion generator 5. Therefore, the air purification assembly can be automatically opened only when the two conditions of people and poor air quality are met. When the air quality reaches a set threshold value, the air purification assembly stops working.

In addition, it can also be set that the air purification assembly is also opened to purify air when nobody is present, and an interval time, for example, 1 hour, can be set at this moment, so that the air detection module 6 will detect the air quality once every 1 hour, and if any one of the concentration of PM2.5, the concentration of the volatile organic compound and the concentration of ammonia in the air exceeds the set threshold, the pore purification assembly will be automatically opened.

The embodiment also provides the function introduction of various keys on the control panel 8:

1. main switch key 81: clicking to start the control system, and displaying the monitoring data values of PM2.5, ammonia gas and VOC on a screen;

2. manual mode switch button 82: clicking to start the air purifier to work;

3. air volume adjusting button 83: clicking to switch air volume, and realizing three-gear adjustment of

gears

1, 2 and 3 by controlling the rotating speed of a fan 3;

4. automatic mode switch button 84: the automatic working mode is started in a single click mode, a human body microwave radar inductive switch 7 monitors whether people exist around, a sensor is started to detect the content of PM2.5, VOC and ammonia in the air under the condition that people exist, and if the content exceeds a set threshold value, an air purifier is started;

under the condition of no people, automatically detecting the content of PM2.5, VOC and ammonia gas in the air at set time intervals (such as 1 hour and 2 hours), and starting the air purifier if the content exceeds a set threshold value;

5. timing key 85: setting the working time of the manual mode: set 30 minutes, 2 hours, 4 hours.

The above, only be the embodiment of the present invention, however, the design concept of the present invention is not limited to this, and any person skilled in the art is in the technical scope of the present invention, and it is right to utilize this concept to perform insubstantial changes, all belonging to the act of infringing the protection scope of the present invention.
