[0025] As shown in Figure 3As shown, the negative oxygen ion generating mechanism 3 comprises an ionization chamber 31, a connecting pipe 32 fixedly connected to the left side of the ionization chamber 31 and penetrating the inner cavity thereof, the connecting pipe 32 being fixedly connected with the air supply pipe two 181, a V-shaped partition plate 33 fixedly installed between the inner walls of the ionization chamber 31, two inclined surfaces of the V-shaped partition plate 33 being provided with left-right penetrating installation grooves 34, the inner rings of the two installation grooves 34 being fixedly installed with a plurality of discharge needles 35, a power supply 36 provided at the top of the ionization chamber 31 for supplying power to the discharge needles 35, and an air outlet pipe 37 fixedly connected to the right end of the ionization chamber 31 and penetrating the inner cavity thereof.

[0028] The new air ventilator box 1 is sealed by the quick-release cover plate 2 from the front side by means of the pull handle 21, and the sealing rubber pad 22 is used to improve the sealing performance. When the quick-release cover plate 2 is clamped into the front side of the new air ventilator box 1, the positioning plates 23 on the left and right sides of the front end of the quick-release cover plate 2 will extrude the front side of the inclined surface of the inclined buckle 194 on the opposite surface of the locking control box 191 on the left and right sides of the front end of the new air ventilator box 1, so that the inclined buckle 194 is compressed by the pressing plate 193 to compress the compression spring 192. When the quick-release cover plate 2 is completely clamped into the front side of the new air ventilator box 1, the positioning plates 23 are aligned with the locking control boxes 191 on the left and right sides, and the inclined buckle 194 can be clamped into the buckle groove 24 under the rebounding action of the compression spring 192, thereby limiting the positioning plates 23 and the quick-release cover plate 2. When disassembling, only the pull blocks 196 on one side of the locking control boxes 191 need to be pulled at the same time, so that the pressing plate 193 and the inclined buckle 194 are pulled by the pull rod 195, the inclined buckle 194 is separated from the buckle groove 24, the positioning of the positioning plates 23 is released, and the whole quick-release cover plate 2 can be removed by the pull handle 21, so that the inner cavity of the new air ventilator box 1 is completely exposed, and the exhaust filter mechanism 13, the air supply filter mechanism 14, and the rhombic heat exchange core 12 can be easily disassembled and cleaned, or the exhaust fan 16 and the air supply fan 18 can be repaired.

[0029] The working principle of the new air device capable of providing negative oxygen ions will be described below.

[0030] As Figures 1-5As shown, when the fresh air ventilator box 1 is started, through the driving of the exhaust fan 16, the indoor hot air can be sucked into the inner cavity of the fresh air ventilator box 1 through the exhaust pipe 15, and after being filtered by the exhaust filter mechanism 13 on the right side of the baffle 11, it reaches the lower side of the left side of the baffle 11 through the rhombus heat exchange core 12, and is smoothly discharged to the outside through the exhaust pipe 16. In winter, because the indoor temperature is higher than the outdoor temperature, the heat will be exchanged through the rhombus heat exchange core 12, and the start of the supply fan 18 will heat the external cold air after being filtered and purified layer by layer through the supply filter mechanism 14, and then the air will be discharged to the negative oxygen ion generating mechanism 3 through the supply pipe 18. The air discharged to the indoor air through the supply pipe 18 will first enter the inner cavity of the ionization chamber 31 through the connecting pipe 32, and at the same time, the discharge needle 35 in the mounting groove 34 of the V-shaped baffle 33 is powered through the power supply 36. By using high-voltage electric field technology, the filtered air generates negative ions through the discharge needle 35. The negative ions will combine with the positive ions or particulate matters in the indoor air to make them electrically neutral, and will naturally diffuse with the air, effectively cleaning the air and reducing harmful particles in the air. At the same time, the shape of the V-shaped baffle 33 can make the air source evenly pass through the two mounting grooves 34 and be discharged to the indoor air through the air outlet pipe 37. At the same time, the whole quick-release cover plate 2 is clamped from the front side of the fresh air ventilator box 1 by means of the pull handle 21, so as to be sealed, and the sealing rubber pad 22 is used to improve the sealing performance. When the quick-release cover plate 2 is clamped into the front side of the fresh air ventilator box 1, the positioning plates 23 on the left and right sides of the front end of the quick-release cover plate 2 will extrude the front side of the inclined surface of the inclined surface buckle 194 on the opposite surface of the locking control box 191 on the left and right sides of the front end of the fresh air ventilator box 1, so that the inclined surface buckle 194 compresses the compression spring 192 by means of the pressing plate 193. When the quick-release cover plate 2 is completely clamped into the front side of the fresh air ventilator box 1, the positioning plates 23 are aligned with the locking control boxes 191 on the left and right sides, and the inclined surface buckle 194 can be clamped into the buckle groove 24 under the rebounding action of the compression spring 192, so as to limit the positioning plates 23 and the quick-release cover plate 2. When disassembling, only the pull blocks 196 on one side of the two locking control boxes 191 need to be pulled at the same time, so that the pressing plate 193 and the inclined surface buckle 194 are pulled by means of the pull rod 195, so that the inclined surface buckle 194 is separated from the buckle groove 24, and the positioning of the positioning plate 23 is released, so that the whole quick-release cover plate 2 can be removed by means of the pull handle 21, so that the inner cavity of the fresh air ventilator box 1 is completely exposed, and the exhaust filter mechanism 13, the supply filter mechanism 14 and the rhombus heat exchange core 12 can be disassembled and cleaned, or the exhaust fan 16 and the supply fan 18 can be repaired.

[0031] The above is a detailed description of the present application, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the present application are within the scope of the present application.
