Description

Technical Field

[0001] The utility model relates to the field of disinfection devices and methods in the biomedical industry, and in particular to an air sterilization, disinfection and purification system, specifically to an air purification device capable of sterilization and disinfection. Background Art

[0002] The air purification device adopts advanced physical, chemical and biological purification technologies. Through multiple filtration and disinfection steps, it can remove pollutants such as dust, pollen, bacteria, viruses, harmful gases and odors in the air, providing people with a healthy and fresh living environment.

[0003] There are many existing technologies for air purification devices, such as:

[0004] Chinese Patent Publication No. CN110986217B discloses a sterilizable and disinfectable air purification device, comprising a filter box, an air inlet pipe fixed to one side of the filter box, a first air valve fixed to the outside of the air inlet pipe, a slot fixed to the top and bottom of the inner wall of the filter box, a connecting shell movably connected to the slot, a positioning rod fixed to the inside of the connecting shell, a first telescopic rod fixed to one end of the positioning rod, a first spring sleeved on the outside of the first telescopic rod, a connecting plate fixed to both ends of the first telescopic rod, a clamping rod fixed to one side of the connecting plate, positioning holes formed on both sides of the connecting shell, the clamping rod passing through the positioning holes, and a connecting rod fixed to the upper surface of the connecting shell. The utility model, through the function of the disinfection box, can simultaneously filter and disinfect the air, so that pathogens in the air can be eliminated, which can better protect the health of the user. In addition, the filter screen and the disinfection frame can be flexibly removed, making it easy for the user to replace and clean them.

[0005] Existing air purifiers usually need to use filters to intercept and filter solid particles such as dust and PM10 in the air. As the use time increases, the filtering effect of the filter will gradually become saturated, and the air outlet effect will also be affected, so it needs to be replaced. When replacing the filter, firstly, it is troublesome to disassemble and clean it. Even some more advanced air purifiers require professional technicians to replace and repair them on site when they are disassembled; on the other hand, frequent replacement and maintenance will generate a certain economic burden. In addition, frequent disassembly of the equipment will destroy the integrity of the air purifier and affect the service life of the machine. For example, the above-mentioned patent proposes a sterilizable and disinfecting air purification device, which improves the efficiency of replacement by setting a flexibly removable filter and disinfection frame. However, it does not provide an effective solution to the economic problems of ensuring the integrity of the device and frequently replacing the filter.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example:

[0037] See also Figures 1-8 As shown, the purpose of this embodiment is to provide an air purification device capable of sterilization and disinfection, comprising a housing 10, wherein an air inlet grille 11 and an air outlet 12 are respectively provided on two sides of the housing 10 away from each other; an air inlet assembly 20 is provided inside the housing 10 between the air inlet grille 11 and the air outlet 12, and the air inlet assembly 20 is used to extract air from the outside of the housing 10, and a purification assembly 30 is provided on the side of the air inlet assembly 20 away from the air inlet grille 11, and the purification assembly 30 is used to purify pathogens and particulate matter in the air, and the air inlet assembly 20 can gather the air, and the lower part of the purification assembly 30 is coaxially connected to the limiting assembly 60, and the purification During the air purification process of the component 30, the limit component 60 is used to ensure the stability of the horizontal position of the purification component 30; a toggle component 40 is provided in the air outlet 12, and the toggle component 40 is used to sense the wind force of the air inlet component 20 passing through the purification component 30. A hysteresis pull component 50 is movably connected between the toggle component 40 and the purification component 30. When the air inlet of the purification component 30 is blocked, the toggle component 40 can drive the hysteresis pull component 50 to drive the purification component 30 to rotate a certain angle. When the purification component 30 resumes ventilation, the toggle component 40 can drive the hysteresis pull component 50 to reset.

[0038] When the air purification device is operating normally, the air intake assembly 20 draws air from the outside of the housing 10 through the air intake grille 11, draws the air into the housing 10, and gathers the air drawn into the housing 10 so that all the air passes through the purification assembly 30, while ensuring that the air passes through the side of the purification assembly 30. The air blown out of the air intake assembly 20 is filtered by the purification assembly 30 and then blows the purified air to the outside of the housing 10 through the toggle assembly 40;

[0039] When the filter holes of the purification component 30 are clogged with dust, the wind blown out by the air intake component 20 passes through the purification component 30, and the wind force reaching the toggle component 40 becomes smaller. At this time, the toggle component 40 pulls the hysteresis pulling component 50, and the hysteresis pulling component 50 and the purification component 30 slide relative to each other. At the same time, because there is a certain friction between the hysteresis pulling component 50 and the purification component 30, the hysteresis pulling component 50 drives the purification component 30 to rotate a certain angle, and aligns the part of the purification component 30 that is not blocked by dust with the air outlet of the air intake component 20, so that the air purification device works normally. The wind blown out by the air intake component 20 passes through the purification component 30, and the wind force reaching the toggle component 40 returns to normal. Under the action of its own restoring force, the hysteresis pulling component 50 returns to its original position along the purification component 30.

[0040] First, the specific structure of the toggle assembly 40 is disclosed. The toggle assembly 40 includes a mounting frame 41 disposed in the air outlet 12. A plurality of blades 42 are rotatably connected in the mounting frame 41. A connecting rod 43 is rotatably connected between the plurality of blades 42.

[0041] When the purification component 30 is not blocked and the wind force blowing onto the blades 42 by the air intake component 20 is normal, the blades 42 are blown up by the wind and parallel to the horizontal plane. The air purified by the purification component 30 passes through the air outlet 12 to the outside of the shell 10. When the purification component 30 is blocked by air, the wind blown out by the air intake component 20 passes through the purification component 30 and the wind force reaching the blades 42 will become smaller. The wind force is not enough to blow up the blades 42. The weight of the part of the blade 42 close to the outside of the shell 10 is greater than the weight of the part close to the inside of the shell 10. Under the action of its own gravity, the part of the blade 42 close to the outside of the shell 10 rotates downward. Accordingly, the part close to the outside of the shell 10 drives the connecting rod 43 to move upward. The connecting rod 43 pulls the lagging pulling component 50 to move, so that it drives the purification component 30 to rotate a certain angle until the unblocked part of the purification component 30 is aligned with the air outlet of the air intake component 20, thereby increasing the service life of the purification component 30 and reducing the replacement frequency.

[0042] Next, the specific structure of the hysteresis pull assembly 50 is disclosed. The hysteresis pull assembly 50 includes a clamping block 51 slidably connected to the clamping slot 33. A side of the clamping block 51 away from the filter element 32 is rotatably connected to an elastic cord 52. The elastic cord 52 is slidably connected to a limit pin on its periphery. The bottom of the limit pin is fixedly connected to the housing 10.

[0043] Furthermore, the elastic rope 52 is made of polyurethane rubber, and the surfaces of the block 51 and the slot 33 are provided with an asymmetric texture structure. Due to the material characteristics of the elastic rope 52, when the elastic rope 52 is pulled by the connecting rod 43, the texture of the elastic rope 52 is relatively soft, and it can drive the purification component 30 to rotate a certain angle through the block 51. The texture of the elastic rope 52 is relatively hard when it rebounds, and it can drive the block 51 to reset on the purification component 30. In addition, the surfaces of the block 51 and the slot 33 are treated with a special asymmetric structure, so that when the block 51 is pulled by the elastic rope 52, the friction force when sliding in the slot 33 is relatively large, and when the elastic rope 52 rebounds and drives the block 51 to reset, the friction force between the block 51 and the slot 33 is relatively small.

[0044] Since it is necessary to ensure that the air extracted from the outside of the shell 10 by the air intake assembly 20 can all pass through the purification assembly 30, the air intake assembly 20 includes a limit frame, in which a fan 21 is rotatably connected. The limit frame is provided with a gathering cover 22 on the side away from the air intake grille 11, and the fan 21 is driven by a motor.

[0045] The improvement is that after the power is turned on, the motor drives the fan 21 coaxially connected to its own output shaft to rotate, and the fan 21 draws the air outside the shell 10 into the shell 10, and blows it into the purification component 30 after being gathered by the gathering cover 22. The gathering cover 22 is set to a duckbill shape, so that all the air drawn into the shell 10 by the fan 21 can pass through the eccentric part of the purification component 30.

[0046] Since it is necessary to purify the indoor air and absorb the solid particles and pathogens therein, the purification component 30 includes a base, a main rod 31 is provided at the top center of the base, a filter element 32 is rotatably connected to the top of the main rod 31, and a card slot 33 is provided at the bottom edge of the filter element 32.

[0047] The improvement is that the filter element 32 is provided with replaceable activated carbon, which can purify the indoor air by removing solid particles such as dust, pollen, bacteria, and harmful gases such as volatile organic compounds in the air. Activated carbon purification belongs to the existing technology and will not be elaborated on here.

[0048] Since it is necessary to ensure the stability of the horizontal position of the purification component 30 during operation, the limiting component 60 includes a ratchet 61 coaxially connected to the main rod 31, and an annular frame is provided on the periphery of the ratchet 61. A plurality of pawls 62 are rotatably connected inside the annular frame, and the ends of the plurality of pawls 62 away from the annular frame are clamped with the periphery of the ratchet 61.

[0049] The improvement lies in that the ratchet 61 is fixed by the main rod 31, and its outer ring has a series of ratchet teeth arranged at even intervals. When an external force acts on the ratchet 61, the ratchet teeth will start to rotate under the action of torque. The special shape of the ratchet teeth makes them only able to rotate in one direction and be blocked in the other direction. When the ratchet 61 rotates, they will pass through the adjacent ratchet teeth one by one. This transmission method effectively transmits the input torque to the next ratchet tooth, realizing power transmission. This transmission method of only transmitting one ratchet tooth at a time makes the ratchet 61 have higher accuracy and stability when transmitting power.

[0050] In summary, the working principle of this solution is as follows: when the filter element 32 is not blocked, the fan 21 rotates, drawing air outside the housing 10 into the housing 10 through the air inlet grille 11. The fan 21 blows the air toward the eccentric portion of the filter element 32. After being purified by the activated carbon and other substances inside the filter element 32, the fan 21 blows the blades 42 upward when the wind force is sufficient, thereby blowing the purified air to the outside of the housing 10.

[0051] When the filter element 32 is clogged with dust, the wind blown by the fan 21 passes through the filter element 32, and the wind force reaching the blades 42 will become smaller, and the wind force will be insufficient to blow up the blades 42. The weight of the blades 42 close to the outside of the shell 10 is greater than the weight of the blades 42 close to the inside of the shell 10. Under the action of its own gravity, the blades 42 close to the outside of the shell 10 rotate downward. Accordingly, the blades 42 close to the outside of the shell 10 will drive the connecting rod 43 to move upward. The connecting rod 43 pulls the elastic rope 52, and the elastic rope 52 drives the block 51. The block 51 drives the filter element 32 to rotate a certain angle until the unblocked part of the filter element 32 is aligned with the gathering cover 22. At this time, the wind force blown by the fan 21 to the blades 42 is restored, thereby increasing the service life of the filter element 32 and reducing the replacement frequency.
