[0002] As air quality declines, people breathe in harmful gases that can damage their health. In winter, windows are often closed, and with many students in a classroom, each student's exhaled air contains carbon dioxide, leading to an increase in carbon dioxide levels in the classroom. Furthermore, chalk dust from wiping the blackboard during teaching further degrades the air quality. Therefore, it is necessary to use a sterilizer to treat the air.

[0003] Currently, sterilizers in use first inhale and then exhale air to disinfect indoor air. After a period of use, the effectiveness of the filter panel decreases. Moreover, the filter panels used in current sterilizers are not easy to replace, requiring the disassembly of a large number of parts, which is time-consuming. Therefore, a filter panel replacement mechanism for sterilizers is proposed to solve the above problems. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example

[0030] Reference Figures 1-4This utility model provides a technical solution: a filter panel replacement mechanism for a sterilizer, including a housing 1, a filter plate replacement mechanism 3, and an air intake mechanism 4. An air outlet cover 2 is installed on the top of the housing 1. The filter plate replacement mechanism 3 includes a groove 31, which is located at the top of the housing 1. A connecting block 311 is installed inside the groove 31. A rotating rod 32 is rotatably mounted on the connecting block 311, and a torsion spring 321 is provided on the connecting block 311. A clamping plate 33 is mounted on the rotating rod 32, and a baffle 331 is installed on the connecting block 311 at a position opposite to the clamping plate 33. The air intake mechanism 4 is located on both sides inside the housing 1.

[0031] By providing a groove 31 inside the housing 1, and installing a connecting block 311 inside the groove 31, a baffle 331 is installed at one end of the connecting block 311, and a rotating rod 32 is rotatably installed at the other end of the connecting block 311. A torsion spring 321 is installed on the rotating rod 32, and a clamping plate 33 is installed on the rotating rod 32. The filter screen plate 43 can be clamped by the clamping plate 33. This device can not only clamp the filter screen plate 43 stably for use, but also replace the filter screen plate 43 without disassembling more parts, saving time and meeting the usage requirements.

[0032] In a preferred embodiment, the air intake mechanism 4 includes a side panel 41, a pre-filter 42, and a filter plate 43. The side panel 41 is snapped into the interior of the housing 1, and a recess 5 is provided on the top of the side panel 41 for operating the installation and removal of the side panel 41. A clamping cylinder 6 is provided on the outer surface of the clamping plate 33. A clamping block 7 is installed on the pre-filter 42. The clamping block 7 is snapped into the interior of the clamping cylinder 6 and the pre-filter 42 is positioned inside the side panel 41. The filter plate 43 is positioned inside the pre-filter 42, and the outer side of the filter plate 43 corresponds to the position of the baffle 331.

[0033] In actual use, this device is placed indoors and connected to an indoor power source. The air extraction element inside the housing 1 draws indoor air into the housing 1. The indoor air enters from the side panel 41 and passes through the pre-filter 42 and filter plate 43 in sequence. Through two filtration processes, the drawn-in air is treated. Then, the treated air is discharged from the top of the housing 1 and returned to the room by the action of the air extraction element. By repeatedly treating the indoor air in this way, indoor air disinfection can be achieved, avoiding harm to students' health.

[0034] To allow air from the classroom to enter the box 1, several air inlet holes 8 are provided on the side panel 41 and are evenly distributed on the outer surface of the side panel 41. The air inlet holes 8 penetrate the interior of the side panel 41 and are used for air intake. In actual use, the air extraction element inside the box 1 draws in the air inside the classroom, and the air enters through the air inlet holes 8, which facilitates the disinfection of the air in the classroom.

[0035] A display screen 9 is provided on the outer surface of the enclosure 1, and a control button 10 is provided on the top of the enclosure 1. A support block 11 is installed at the bottom of the enclosure 1, and the support blocks 11 are evenly distributed at the four corners of the bottom of the enclosure 1.

[0036] In actual use, to increase the air intake, two filter plates 43 are set up and installed symmetrically on the left and right sides inside the box 1. Two sets of filter plate replacement mechanisms 3 are installed inside the box 1, with two filter plate replacement mechanisms 3 in each set. When the air extraction element inside the box 1 is working, air can be introduced through the positions of the two side panels 41 to increase the air intake and quickly disinfect the air in the classroom to meet the requirements.

[0037] Specifically, the working process or working principle of a filter panel replacement mechanism for a sterilizer is as follows: Currently, when a sterilizer is in use, it first draws in air and then exhales air to sterilize the indoor air. After a period of use, the effectiveness of the filter panel decreases. The filter panels used in current sterilizers are not easy to replace, requiring the disassembly of a large number of parts, which wastes time. Therefore, this device was designed to solve this problem.

[0038] This device allows for easy replacement of the filter plate 43. Simply remove the side panel 41 and the pre-filter 42 to remove the filter plate 43. This simplifies operation and saves time. Specifically, when using this device, it can be placed indoors and connected to an indoor power source. The air extraction element inside the housing 1 draws indoor air into the housing 1. The indoor air enters from the side panel 41 and passes through the pre-filter 42 and the filter plate 43 in sequence. Through this double filtration, the drawn-in air is treated. Then, the air extraction element discharges the treated air from the top of the housing 1 and back into the room. By repeatedly treating the indoor air in this way, indoor air disinfection can be achieved, preventing harm to students' health.

[0039] After a period of use, the treatment effect of the filter plate 43 will decrease, and the filter plate 43 needs to be replaced. During the replacement operation, the operator can first remove the side panel 41. By pulling the side panel 41, it can be pulled out from the inside of the box 1. Then, the pre-filter 42 is removed. The pre-filter 42 is connected to the clamping sleeve 6 on the clamping plate 33. Pulling the pre-filter 42 to the outside of the box 1 can remove the pre-filter 42 from the clamping plate 33. At this time, the filter plate 43 will be exposed. By rotating the clamping plate 33, the clamping plate 33 is released from the clamping of the filter plate 43. Then, the filter plate 43 can be pulled out from the inside of the box 1, which is convenient for replacing the filter plate 43.

[0040] When installing the filter plate 43, the clamping plate 33 should also be rotated and lifted upwards so that the filter plate 43 can enter the interior of the housing 1. After the filter plate 43 enters the housing 1, the filter plate 43 can be pushed to move until it abuts against the outer surface of the baffle 331. At this point, the filter plate 43 will not move further. Then, the clamping plate 33 can be controlled to rotate downwards. Under the action of the torsion spring 321, the clamping plate 33 can stably clamp the filter plate 43, and the filter plate 43 is stably installed inside the housing 1. When the clamping plate 33 is adjusted to a vertical position, the clamping cylinder 6 will move to the position corresponding to the clamping block 7. The clamping block 7 on the pre-filter 42 will engage with the clamping cylinder 6, and the pre-filter 42 can be stably installed on the clamping plate 33 and stably set inside the housing 1. Then, the side panel 41 is clamped onto the housing 1 to complete the installation.
