[0002] As urban air pollution worsens, the levels of pollutants such as inhalable particulate matter and dust in urban atmospheres are rising daily. As a result, central air conditioning systems are increasingly being used in large public places. These systems can not only effectively regulate the temperature and humidity of the air in these places, but also filter and purify the air, thereby improving the freshness of the air.

[0003] According to Chinese Patent No. CN217402717U, a micro-electrostatic air intake purification device for central air conditioning is proposed, which includes a shell, a primary filter and a micro-electrostatic module. The shell includes a shell frame, and a control box is fixedly installed at one end of the inner cavity of the shell frame. The primary filter and the micro-electrostatic module are sequentially and detachably installed at the other end of the inner cavity of the shell frame.

[0004] Although the aforementioned patent effectively purifies the air entering the central air conditioning system through the micro-electrostatic module, improving the purification effect, the entire device requires installation bolts and mounting clips for connection and installation when installed with the central air conditioning system. Furthermore, auxiliary tools are needed during installation, making the entire installation process time-consuming and labor-intensive, thus reducing the ease of installation. Utility Model Content

[0005] The purpose of this utility model is to provide a micro-electrostatic filtration device for central air conditioning systems, thereby solving the problems mentioned in the background section. To solve these technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a micro-electrostatic filtration device for central air conditioning, comprising:

[0007] A micro-electrostatic filter frame, wherein fixed covers are fixedly provided on both sides of the micro-electrostatic filter frame;

[0008] The mounting assembly includes a connecting rod, a pressing block fixedly provided at the top of the connecting rod, an elastic block fixedly provided on the outer wall of the pressing block, a first connecting block fixedly provided at the bottom of the connecting rod, a spring fixedly provided at the bottom of the first connecting block, two rotating rods rotatably provided on both sides of the first connecting block, two second connecting blocks provided together by the four rotating rods, and a mounting rod fixedly provided on the opposite side of the two second connecting blocks.

[0009] Furthermore, a fixing groove is provided on both sides of the top of the micro electrostatic filter frame, and the outer wall of the connecting rod penetrates the bottom end of the fixing groove and slides with the fixing groove.

[0010] Furthermore, the bottom end of the spring is fixedly connected to the inner bottom end of the fixing cover.

[0011] Furthermore, the mounting assembly also includes two vertical rods, the top ends of which are respectively fixedly disposed at the bottom ends of the two second connecting blocks, and a slider is fixedly disposed at the bottom end of each of the two vertical rods, the outer wall of which is slidably connected to the inner bottom end of the fixing cover.

[0012] Furthermore, the outer walls of the two mounting rods respectively penetrate both sides of the fixing cover and slide in conjunction with the fixing cover.

[0013] Furthermore, a baffle is slidably provided on one side of the fixing groove, and the length of the baffle is longer than the length of the fixing groove. A lever is fixedly provided on the side of the top of the baffle.

[0014] Furthermore, two auxiliary rods are provided through the other two sides of the top of the micro-electrostatic filter frame, and a horizontal plate is fixed to the bottom of each of the two auxiliary rods.

[0015] This utility model has the following beneficial effects:

[0016] This invention, by incorporating a push block and an installation rod, allows the micro-electrostatic filter frame to be engaged with the bottom of a central air conditioner. Pressing the push block upwards causes it to move upwards, which in turn moves the connecting rod upwards. This upward movement of the connecting rod compresses a spring via a first connecting block. Simultaneously, the upward movement of the first connecting block causes two second connecting blocks to move in opposite directions via four rotating rods, bringing the installation rod into contact with the inner bottom of the central air conditioner until the elastic block engages with the locking holes on both sides of the micro-electrostatic filter frame. This method facilitates the installation of the micro-electrostatic filter frame, saving time and effort throughout the installation process without the need for auxiliary tools, thus improving the ease of installation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a micro electrostatic filtration device for central air conditioning, comprising:

[0027] Micro-electrostatic filter frame 1, with fixed covers 2 fixed on both sides of the micro-electrostatic filter frame 1;

[0028] The micro-electrostatic filter frame 1 is used to filter and purify air. It uses a high-voltage electric field (such as positive corona discharge or dielectric strong electric field) to charge particulate matter (PM2.5, pollen, etc.) in the air, and then adsorbs the charged particles through the dust collection plate or honeycomb electric field structure.

[0029] Mounting component 3 includes a connecting rod 31, a pressing block 32 fixedly provided at the top of the connecting rod 31, an elastic block 33 fixedly provided on the outer wall of the pressing block 32, a first connecting block 34 fixedly provided at the bottom of the connecting rod 31, a spring 35 fixedly provided at the bottom of the first connecting block 34, two rotating rods 36 rotatably provided on both sides of the first connecting block 34, two second connecting blocks 37 are provided together by the four rotating rods 36, and mounting rods 38 are fixedly provided on opposite sides of the two second connecting blocks 37.

[0030] When the top of the first connecting block 34 contacts the inner top of the micro-electrostatic filter frame 1, one end of the mounting rod 38 is on the same vertical plane as one side of the fixed cover 2, and the rotating rod 36 is rotatably connected to the second connecting block 37.

[0031] The top two sides of the micro-electrostatic filter frame 1 are provided with fixing grooves 11, and the outer wall of the connecting rod 31 passes through the bottom end of the fixing groove 11 and slides with the fixing groove 11.

[0032] The top of both sides of the micro-electrostatic filter frame 1 are provided with a card hole that matches the elastic block 33, and the card hole is connected to one side of the fixing groove 11.

[0033] The bottom end of the spring 35 is fixedly connected to the inner bottom end of the fixed cover 2.

[0034] The mounting assembly 3 also includes two vertical rods 39, the top ends of which are fixedly mounted on the bottom ends of the two second connecting blocks 37 respectively, and the bottom ends of the two vertical rods 39 are each fixedly mounted with a slider 310, the outer wall of the slider 310 being slidably connected to the inner bottom end of the fixing cover 2.

[0035] The slider 310 is T-shaped and is used to assist in the movement and limit the second connecting block 37. The second connecting block 37 moves stably. The bottom of the fixed cover 2 has grooves on both sides that are adapted to the slider 310.

[0036] The outer walls of the two mounting rods 38 pass through both sides of the fixed cover 2 and slide in fit with the fixed cover 2.

[0037] Working principle: After the micro-electrostatic filter frame 1 is snapped into the bottom of the central air conditioner, the two push blocks 32 are pressed upwards respectively. The push blocks 32 move upwards, which in turn drives the elastic block 33 and the connecting rod 31 to move upwards respectively. The upward movement of the connecting rod 31 compresses the spring 35 through the first connecting block 34. At the same time, the upward movement of the first connecting block 34 drives the four rotating rods 36 to rotate. The rotation of the four rotating rods 36 drives the two second connecting blocks 37 to move in opposite directions, which in turn drives the two mounting rods 38 to move outwards, so that the mounting rods 38 contact the inner bottom of the central air conditioner until the elastic block 33 engages with the snap holes on both sides of the micro-electrostatic filter frame 1. This method facilitates the installation of the micro-electrostatic filter frame 1. The entire installation process is time-saving and labor-saving, and no auxiliary tools are needed, which improves the convenience of device installation.

[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] A baffle 12 is slidably provided on one side of the fixed groove 11, and the length of the baffle 12 is longer than the length of the fixed groove 11. A toggle block 13 is fixedly provided on the side of the top of the baffle 12.

[0040] When the elastic block 33 engages with the locking holes on both sides of the micro-electrostatic filter frame 1, the bottom end of the baffle 12 and the top end of the pressure block 32 are at the same horizontal plane.

[0041] Two auxiliary rods 4 are provided through the top two sides of the micro electrostatic filter frame 1, and a horizontal plate 5 is fixed at the bottom of each of the two auxiliary rods 4.

[0042] The auxiliary rod 4 is rotatably engaged with the micro-electrostatic filter frame 1, and the auxiliary rod 4 can only rotate outward by ninety degrees.

[0043] Working principle: After the micro-electrostatic filter frame 1 is installed at the bottom of the central air conditioner, rotate the two auxiliary rods 4. The rotation of the auxiliary rods 4 drives the horizontal plate 5 to rotate, so that the horizontal plate 5 contacts the bottom of the central air conditioner. This can help to install and fix the micro-electrostatic filter frame 1, thereby improving its installation firmness. Then, move the toggle block 13 outward. The outward movement of the toggle block 13 drives the baffle 12 to move outward until the baffle 12 covers the fixing groove 11. This not only improves the overall aesthetics, but also helps to limit the position of the push block 32, thereby improving the overall stability of the installation component 3 after installation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
