In an embodiment, as shown in fig. 4 and 10, the front cover inner side 111 is further protruded with two pressing strips 113, the front cover 11 presses the air inlet filter element 24 to the front side 21 of the frame 2 by the two pressing strips 113, so that the air inlet filter element 24 is sandwiched between the pressing strips 113 of the front cover inner side 111 and the front side 21. When the air inlet filter element 24 is to be replaced, the air inlet filter element can be easily replaced only by detaching the front cover 11.
At least one high-voltage electric field sterilization module 3 is used for electrifying the electrode plates by high voltage, so that germs in the air can be eliminated when the air passes through the electrode plates, and the purpose of high-voltage sterilization is achieved. The number of the high voltage electric field sterilization modules 3 may be one or two, and in this embodiment, two are taken as an example and are respectively configured corresponding to the two air inlet hole sets 1223.
The high-voltage electric field sterilization module 3 is also arranged in the airflow channel C. Specifically, each high-voltage electric field sterilization module 3 includes a first electrode sheet 31 and a second electrode sheet 32, wherein each first electrode sheet 31 is disposed on the front side 21 of the frame 2, and each second electrode sheet 32 is disposed on the front cover inner side surface 111 of the front cover 11. Since the front cover inner side surface 111 and the front side 21 are spaced apart from each other, the first electrode sheet 31 and the second electrode sheet 32 of each hv electric field sterilization module 3 are also spaced apart from each other (and are arranged side by side with each other), so that a space S can be formed between each first electrode sheet 31 and each second electrode sheet 32 as shown in fig. 10. As shown in fig. 10, the airflow path C passes through each of the spaces S.
The airtight cover 5 is a soft cover body, and therefore can be used to cover the nose and mouth portion directly to produce an airtight effect. The airtight cover 5 is disposed on the rear housing outer side surface 122 and has a breathing chamber 51.
The fan 4, the battery module B, the high voltage generator P, and the control module 6 are all disposed on the frame 2. Wherein, the fan 4 is communicated with the frame port 23 and the breathing cavity 51; the battery modules B are used for supplying power, and the number of the battery modules B may be one or more than two, and two are taken as an example in the present embodiment for description; the control module 6 is electrically connected with the high-voltage electric field sterilization module 3, the fan 4 and each battery module B; the high voltage generator P is electrically connected with the control module 6 and each high voltage electric field sterilization module 3.
As shown in fig. 3 and 7, the rear case 12 is further provided with a vent hole group 125 and an exhaust hole group 126. As shown in fig. 7 and 8, the ventilation hole group 125 communicates between the breathing chamber 51 and the fan 4; the exhaust hole set 126 is communicated with the breathing cavity 51.
In addition, this application wearing formula air purification device still includes bunch R as shown in fig. 11, and bunch R sets up in the both ends of shell subassembly 1 and has bunch knot subassembly (including tail-end knot and adjustable bunch knot) R1. When the wearable air purification device is worn, the user only needs to tie the wire harness R to the back brain and the back neck of the user, and then the wire harness buckle component R1 is utilized to adjust the tightening degree of the wire harness R to the user.
Thus, as shown in fig. 11, the user wears the wearable air purification device on the nose and mouth of the human face, and the airtight cover 5 covers the nose and mouth to generate airtightness. At this time, as shown in fig. 5 to 11, when the user controls the fan 4 to start operating via the control module 6, so that the outside air enters the wearable air purification apparatus of the present application from the air inlet hole sets 1223, the outside air will enter the breathing cavity 51 after passing through the separation spaces S and the air inlet filter 24. Specifically, the air flowing in the air flow channel C will pass through each of the spaces S, so that the high voltage generator P applies high voltage to the first electrode plate 31 and the second electrode plate 32 in each of the spaces S to eliminate germs in the air, thereby achieving the effect of high-pressure sterilization; then, the sterilized air after the autoclaving is filtered into clean air through the air inlet filter element 24; finally, the sterilized and filtered air will be inhaled into the respiratory cavity 51 through the set of ventilation holes 125 by the nose, so that the sterilized and filtered air is inhaled by the user using the wearable air purification device of the present application.
It should be noted that, because the air flow channel C of the wearable air purification device of the present invention is only V-shaped with a large included angle, and the only obstacle for the air flowing in the air flow channel C is only the air inlet filter 24 (and only some Xu Zuli is generated), when the control module 6 drives the fan 4 to suck the external air from each air inlet hole set 1223 into the breathing cavity 51 through the air flow channel C, compared with the prior art, the wearable air purification device of the present invention will only have some Xu Zuli, so that the user can inhale more smoothly.
It should be noted that, as shown in fig. 10 and fig. 11, since the air-tight cover 5 is protruded on the outer side surface 122 of the rear shell of the wearable air purification device, when a user wears the wearable air purification device on the nose and mouth of a human face, a distance D shown in fig. 11 will occur between the outer side surface 122 of the rear shell and the human face through the air-tight cover 5. The air inlet hole sets 1223 are opened on both sides of the rear case outer surface 122. Therefore, the two air inlet hole groups 1223 formed on the two sides of the outer side surface 122 of the rear housing will be away from the human face to ensure smooth air inlet, which can further improve the smoothness of the user when inhaling.
In order to prevent the external air from entering the breathing cavity 51 without sterilization and filtration, as shown in fig. 4, 8 and 9, the wearable air purification device of the present application further includes an air vent 7, a gap G is further provided on the bottom edge of the housing assembly 1 corresponding to the air vent set 126, and the air vent 7 is disposed in the housing assembly 1 corresponding to the gap G. The exhaust gate 7 is disposed at the bottom of the frame 2, and includes a check valve 71 and an exhaust filter element 72, and the flow direction of the check valve 71 is exhausted from the housing assembly 1 through the gap G. Therefore, ambient air that is not sterilized and unfiltered will never enter the breathing chamber 51 via the gap G and the set of exhaust holes 126.
In order to prevent the fan 4, the control module 6, the battery modules B, and the high voltage generator P from obstructing the airflow channel C, as shown in fig. 2, 4, 5, and 10, the rear side 22 of the frame 2 is formed with a middle concave portion 221 and two side concave portions 222 respectively located at two sides of the middle concave portion 221, the middle concave portion 221 is opened with the frame through opening 23, the fan 4 is disposed in the middle concave portion 221, each battery module B is disposed in each side concave portion 222, and the control module 6 and the high voltage generator P are respectively disposed at two sides of the bottom side of the frame 2 to avoid the exhaust damper 7 (the exhaust damper 7 is disposed in the middle of the bottom side of the frame 2).
