Detailed Description

The utility model is further described below with reference to the drawings and examples, which are not to be construed as limiting the utility model.

The air purifying device is arranged between the air conditioning panel of the courtyard machine and the air conditioning main body of the courtyard machine. As shown in fig. 1a, 1b and 2, the air purifying device provided by the embodiment of the utility model comprises a fresh air foam frame 1, wherein the middle of the fresh air foam frame 1 is a square return air inlet 2, and eight air outlets 3 are arranged on the peripheral body. The fresh air foam frame 1 can also be made of a lightweight material with relatively heat insulation according to the requirement; the return air inlet 2 may be arranged in other rectangular shapes, such as rectangular; the number of the air outlets 3 may also be selected, for example, one air outlet or three air outlets on each side. A filter screen component 4 is assembled in the air return opening 2 in the middle of the fresh air foam frame 1, and the filter screen component 4 is fixedly connected with the fresh air foam frame 1 through screws. And the filter screen assembly 4 comprises a filter screen frame 5 and an adsorption net member 6, wherein the adsorption net member 6 comprises a frame and an adsorption net adhered on the frame. The frame of the adsorption net member 6 can be quickly connected with or detached from the filter screen frame 5 through an elastic shifting piece mechanism 7 arranged on the periphery.

In the embodiment of the air purifying device provided by the utility model, as shown in fig. 2 to 4b, the filter screen frame 5 of the filter screen assembly 4 is formed by butt joint of four filter screen frame edges 8 with the same length end to form a frame adapting to the shape of the air return opening 2 of the fresh air foam frame 1. In this embodiment, one end of the filter screen frame edge 8 is a protruding structure 9 provided with a screw via hole 10, the other end of the filter screen frame edge 8 is a groove structure 11, and screw holes 12 are provided in the groove structure 11 along the axial direction (length direction) of the filter screen frame edge 8. After the protruding structure 9 at one end of one filter screen frame edge 8 is inserted into the groove structure 11 at one end of the other filter screen frame edge 8, two adjacent filter screen frame edges 8 can be fixedly connected at right angles through the screw through holes 10 and screw holes 12 by using screws. Thus, the four filter screen frame edges 8 are connected end to end, and the filter screen frame 5 can be installed. The external dimension of the adsorbing net member 6 corresponds to the shape and dimension of the inner ring of the filter screen frame 5, the adsorbing net member 6 is clamped in the inner ring of the filter screen frame 5, and the adsorbing net member 6 and the filter screen frame 5 can be completely fixed by the elastic pulling piece mechanism 7 (as shown in fig. 5). In addition, one side of the filter screen frame edge 8 is provided with a wiring stop block 13; the other side edge of the filter screen frame edge 8 is provided with two countersunk through holes 14 which are used for being connected with the fresh air foam frame 1, and two boss countersunk screw holes 15 are also arranged separately, namely an annular boss 19 is arranged on the surface of the boss countersunk screw holes 15 (refer to fig. 4b and 5). The screen frame 5 is mainly used as an intermediate connecting member between the adsorption screen member 6 and the fresh air foam frame 1. The integrated frame structure can also be adopted for manufacturing, but the size is larger, the die cost is higher, and the preparation difficulty is higher.

As shown in fig. 2 and 5, the elastic tab mechanism 7 includes: the lower half is threaded and the upper half is a self-tapping screw 16 with a pad of the polish rod, while the diameter of the polish rod section is larger than the diameter of the threaded section to form a polish rod step. The polished rod of the tapping screw 16 is sequentially sleeved with a spring washer 17 and a sheet metal elastic pulling piece 18. The tapping screw 16 is screwed into the boss countersunk head screw hole 15 on one side of the filter screen frame edge 8, and when the polished rod step contacts with the countersunk head step of the boss countersunk head screw hole 15, the screw is connected in place. The spring washer 17 and the metal plate elastic poking piece 18 are sleeved on the polish rod of the self-tapping screw 16, and the metal plate elastic poking piece 18 is driven to rotate around the self-tapping screw 16, so that the adsorption net member 6 and the filter screen frame 5 can be connected or detached and inclined. In this embodiment, the sheet metal elastic pulling piece 18 is in a strip shape with two bent ends, and when the sheet metal elastic pulling piece 18 is assembled and disassembled, the sheet metal elastic pulling piece 18 is convenient to rotate. The surface of the sheet metal elastic poking piece 18 facing the frame of the adsorption net member 6 is provided with positioning convex points 20. After the installation, the positioning convex points 20 on the side surface of the metal plate elastic poking piece 18 elastically press the frame of the adsorption net member 6, so that abnormal sound generated by vibration of the adsorption net member 6 during the operation of the unit can be prevented.

As shown in fig. 5, when the polished rod step of the tapping screw 16 contacts with the step of the boss countersunk head screw hole 15, the screw is fixed in place, and the tapping screw 16 can not rotate downwards any more, i.e. the screw can be prevented from rotating downwards all the time to flatten and compress the spring washer 17, so that the sheet metal elastic poking piece 18 is not easy to rotate. At this time, the metal plate elastic poking piece 18 connects and fixes the adsorption net member 6 and the filter screen frame 5, and the spring washer 17 is only in a half-compressed state. The elastic force of the spring washer 17 enables the metal plate elastic poking piece 18 to be pressed on the table surface of the boss 19 of the boss countersunk head screw hole 15, so that certain static friction force exists between the metal plate elastic poking piece and the boss countersunk head screw hole, and the friction force can prevent the metal plate elastic poking piece 18 from freely rotating so as to prevent the adsorption net member 6 from falling off. Because the spring washer 17 separates the sheet metal elastic poking piece 18 from the head of the tapping screw 16, the pretightening force of the tapping screw 16 is larger than the friction force between the spring washer 17 and the head of the tapping screw 16 in the rotation process of the sheet metal elastic poking piece 18, and therefore the tapping screw 16 cannot be loosened to cause connection failure no matter how the sheet metal elastic poking piece 18 rotates back and forth. Therefore, the self-tapping screw 16 is not required to be removed when the adsorbing net member 6 is detached after sales.

As shown in fig. 2, screw hole members are provided around the inner periphery of the return air inlet 2 of the fresh air foam frame 1 of the air purification device of the present utility model. Referring to fig. 1a, in this embodiment, the screw hole members are three sets of sheet metal fixing parts, namely, a first sheet metal fixing part 21 and a second sheet metal fixing part 22 which are arranged on two corners of the upper side of the lee surface of the fresh air foam frame 1; and a third sheet metal fixing part 23 arranged on the lower side of the lee surface of the fresh air foam frame 1. The three sets of sheet metal fixing part bodies are fixed on the fresh air foam frame 1, and threaded holes 24 for connecting the filter screen assembly 4 extend from the bodies of the three sets of sheet metal fixing part bodies to the inner side of the air return opening 2 of the fresh air foam frame 1. During installation, the filter screen assembly 4 is embedded into the air return opening 2 of the fresh air foam frame 1 from the windward side of the fresh air foam frame 1, and is connected with the threaded holes 24 of the screw hole members through the countersunk through holes 14 of the filter screen frame edge 8 in a screwed mode, so that the filter screen assembly 4 is fixed with the fresh air foam frame 1 (as shown in fig. 1 b), and the plane of the filter screen assembly 4 can be flush with the plane of the fresh air foam frame 1 at the windward side. Because the countersunk through holes 14 of the filter screen frame edge 8 and the elastic shifting piece mechanism 7 are positioned on the windward side of the fresh air foam frame 1 to face outwards, the filter screen assembly 4 does not need to be detached integrally when the adsorption net member 6 is maintained or replaced on a daily basis. The adsorption net member 6 and the filter screen frame 5 can be connected or detached by only rotating the sheet metal elastic pulling piece 18. If the whole filter screen assembly 4 needs to be removed for maintenance, the screws in the countersunk through holes 14 are removed. The other surface (lee surface) of the filter screen frame 5 is provided with a plurality of wiring stoppers 13 for restricting wires of the negative ion generating carbon brush 25.

As shown in fig. 1a and 1b, one to two carbon brushes 25 for generating negative ions are arranged at the air outlets 3 around the lee side of the fresh air foam frame 1, and the matched adsorption net adopts an electrostatic adsorption net. Because anion generation carbon brush 25 can be to the air emission anion, according to the air supply principle of the air conditioner of the raise-air machine, locate the air outlet 3 of fresh air foam frame 1 leeward face with anion generation carbon brush 25, the high-speed air current that blows out carries the anion together to enter into indoor to with the particulate matters in the air, like particulate matters such as PM2.5, PM10 adhere to, when the air that carries the pollutant particulate matter passes through return air inlet 2 of fresh air foam frame 1, will be adsorbed on the net face by the electrostatic adsorption net to reach the effect of air-purifying. In addition, if ventilation is required when the indoor carbon dioxide concentration is too high, the user can open the fresh air ports 27 on the upper two corners of the fresh air foam frame 1 to suck a small amount of fresh air. Due to the combined action of the adsorption net member 6 and the negative ion carbon brush 25, the concentration of dust, PM2.5 and the like in the indoor air can be kept at a very low level. The inner wall of the air return opening 2 of the fresh air foam frame is also provided with a semicircular main wire passing groove 26 for the connecting wires between the main body and the panel of the air conditioner of the courtyard machine to pass through, and a plurality of small wire passing grooves for the insulating wires of the negative ion generating carbon brush 25 to pass through are arranged on the leeward surface of the fresh air foam frame 1. The width and the height of all the trunking are smaller, only wires are allowed to pass through, and the trunking is sealed as much as possible, so that condensate water generated by cold air at the air outlet 3 flowing back to the air return opening 2 during the refrigeration of the raise boring machine can be effectively prevented.

According to the utility model, the filter screen component is arranged at the return air inlet of the fresh air foam frame, and the adsorption net component in the filter screen component can be quickly and conveniently connected with or detached from the filter screen frame by rotating the metal plate elastic shifting plate in the elastic shifting plate mechanism, so that the operation is reliable, and the structure is simple. So that the cleaning and maintenance of the adsorbing net member can be easily replaced. The whole filter screen assembly can be easily assembled, disassembled, maintained or replaced through screw connection. In addition, the indoor circulating air can be purified still under the severe climate environment where the traditional fresh air input device cannot work, so that the excellent air environment is maintained.
