Description

Technical Field

[0001] The utility model belongs to the technical field of air purification, and in particular relates to a cabinet-type air purification device. Background Art

[0002] Cabinet air purification equipment is a device used to clean indoor air. Its main function is to remove pollutants such as dust, pollen, bacteria, viruses, volatile organic compounds (VOCs) and other pollutants in the air through filtering and purification technology. The air purification equipment has a built-in fan and several filters. After the fan is started, the air enters the equipment from the bottom and is purified when passing through the filter. The purified gas is discharged from the upper part of the equipment, thereby providing a cleaner indoor environment, reducing the occurrence of allergic reactions and respiratory diseases, and improving the quality of life.

[0003] However, the existing cabinet air purification equipment still has some shortcomings in purification methods. Although the existing air purification equipment is equipped with a variety of filter components, its purification method is relatively simple, mainly relying on the physical filtration and chemical adsorption of each filter. When the filter is clogged, if it is not replaced in time, the purification capacity of the air purification equipment will be greatly reduced, and it is easy to produce odor. Therefore, the cabinet air purification equipment still has shortcomings in the comprehensive purification effect, and it is difficult to fully deal with complex air pollution problems. In order to improve the purification effect, it is urgent to develop a more diversified and efficient air purification equipment. Utility Model Content

During the air purification process, after the fan is started, the air at the bottom of the cabinet enters from the air inlets around it, and passes through multiple filter components in turn. The filter components physically filter and chemically adsorb the air to obtain primary purified air. The primary purified air flows to the air outlet of the cabinet under the action of the fan and the guide plate. The airflow blows a large number of positive and negative oxygen ions stimulated by the positive and negative oxygen ion generator into the air, and performs secondary purification on the primary purified air. It can further purify odors, harmful gases, bacteria, viruses and microorganisms in the air, and can eliminate static electricity, and gather positively charged fine dust, pollen, smoke and other pollutant particles, so that the pollutant particles remaining in the primary purified air are easier to settle, thereby obtaining comprehensive purified air. When the filter component is blocked, the cabinet air purification equipment can still maintain a good purification effect.

[0015] As a further optimization solution of the utility model, a mounting frame for fixing the fan and the positive and negative oxygen ion generators is provided inside the cabinet, and three rows of positive and negative oxygen ion generators are arranged on the mounting frame.

[0028] Example

[0029] like Figure 1-3As shown, a cabinet-type air purification device includes a cabinet 1 and a fan 2. The bottom and top of the cabinet 1 are respectively provided with an air inlet 3 and an air outlet 4, and also includes a plurality of filter components 5. The filter components 5 are detachably arranged on the inner side of the cabinet 1, and the fan 2 is located above the filter components 5 in the cabinet 1. A plurality of positive and negative oxygen ion generators 6 are arranged on one side of the air outlet 4, and an arc-shaped guide plate 7 is arranged between the air outlet 4 and the air outlet of the fan 2. A mounting frame 9 for fixing the fan 2 and the positive and negative oxygen ion generators 6 is provided on the inner side of the cabinet 1. The positive and negative oxygen ion generators 6 on the mounting frame 9 are arranged in three rows, and each row is provided with two positive and negative oxygen ion generators 6. A through slot corresponding to the fan 2 is provided on the mounting frame 9. During the air purification process, after the fan 2 is started, the air at the bottom of the cabinet 1 enters from the air inlets 3 around it, and passes through multiple filter components 5 in sequence. The filter components 5 physically filter and chemically adsorb the air to obtain primary purified air. The primary purified air flows to the air outlet 4 of the cabinet 1 under the action of the fan 2 and the guide plate 7. The airflow blows a large number of positive and negative oxygen ions stimulated by the positive and negative oxygen ion generator 6 into the air, and performs secondary purification on the primary purified air. It can further purify odors, harmful gases, bacteria, viruses and microorganisms in the air, and can eliminate static electricity, gather pollutant particles such as dust, pollen, bacteria, smoke, etc. with positive charges, and make the pollutant particles remaining in the primary purified air easier to settle, thereby obtaining comprehensive purified air. When the filter component 5 is blocked, the equipment can still maintain a good purification effect.

[0030] Specifically, a slide groove 8 for positioning the filter assembly 5 is arranged opposite to each other on the inner wall of the cabinet 1. The filter assembly 5 includes a first filter component 51 and a second filter component 52, wherein the first filter component 51 is used to filter out large particle pollutants, and the second filter component 52 is used to perform secondary filtering on the air. The second filter component 52 is provided with a filter interlayer 53 for diverting air on the upper and lower sides, and a plurality of through holes are evenly arranged on the filter interlayer 53. By providing the filter interlayer 53, the air entering the cabinet 1 is evenly distributed in the first filter component 51 and the second filter component 52 during the rising process, thereby avoiding uneven air purification.

[0031] Furthermore, the first filter component 51 includes a first frame structure 511 and a zigzag filter screen 512 disposed inside the first frame structure 511. A shaping frame 513 is disposed on the filter screen 512, and a fixing member 514 for fixing the shaping frame 513 is disposed on the first frame structure 511. The fixing member 514 is fixedly disposed at the middle of the top of the first frame structure 511 and is fixedly connected to the shaping frame 513 below. The shaping frame 513 cooperates with the fixing member 514 to fix the filter screen 512 in a zigzag shape, thereby increasing the filtering area of ​​the filter screen 512 and preventing the filter screen 512 from affecting the filtering effect due to abnormal deformation.

[0032] The second filter component 52 includes a second frame structure 521 and a plurality of filter elements 522 disposed inside the second frame structure 521. The cross section of the filter element 522 is rectangular or spindle-shaped. The filter element 522 can be a physical filtration type filter element or a chemical adsorption type filter element, wherein the material of the physical filtration type filter element can be porous fiber material, activated carbon, etc., and the material of the chemical adsorption type filter element can be a porous material containing an adsorbent. In addition, the spindle-shaped filter element 522 can prevent part of the air from passing through the second filter component 52 without being filtered by the filter element 522.

[0033] The chute 8 is divided into a pair of first trough bodies 81, a pair of second trough bodies 82 and two pairs of third trough bodies 83. The first trough body 81, the second trough body 82 and the third trough body 83 correspond to the first filter component 51, the second filter component 52 and the filter interlayer 53 respectively. The pair of second trough bodies 82 is located between the two pairs of third trough bodies 83, and the two pairs of third trough bodies 83 are located above the pair of first trough bodies 81. After the rear cover of the cabinet 1 is opened, the first filter component 51, the second filter component 52 and the filter interlayer 53 can be inserted or removed from the corresponding chute 8 to facilitate the replacement of the filter. The corresponding filter assembly 5 can also be selected according to the actual application scenario of the air purification equipment to avoid filter blockage and improve the adaptability of the equipment to the environment.
