[0002] Car air conditioning is one of the important comfort features in a car. Its function is to adjust the temperature, humidity and air quality in the car to provide a comfortable driving environment for the driver and passengers. In the car air conditioning system, the air filter is an indispensable component. It can effectively filter out dust, pollen, bacteria and other impurities in the air entering the car to ensure the cleanliness and health of the air in the car.

[0003] At present, the existing air filter devices for automobile air conditioners have some shortcomings in actual use. For example, it is inconvenient to replace the filter elements of some air filter devices. Usually, tools are needed to disassemble multiple parts to replace the filter elements. The operation process is cumbersome and time-consuming, which brings inconvenience to users. In addition, the connection structure between the splints of some air filter devices is not stable enough. During the driving of the car, due to factors such as vibration, the splints are easily loosened, thereby affecting the fixing effect of the filter element and reducing the filtering efficiency. Some air filter devices have poor sealing performance, so that some unfiltered air may enter the car, affecting the air quality in the car. Summary of the invention

[0023] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, a technical solution provided by the present invention is:

[0025] An air filter device for automobile air conditioner, comprising a clamping plate 1 and a clamping plate 2, wherein the clamping plate 1 is arranged just above the top end of the clamping plate 2, a filter element 3 is arranged between the inner sides of the clamping plate 1 and the clamping plate 2, a positioning mechanism is arranged between the outer sides of the clamping plate 1 and the clamping plate 2, the positioning mechanism comprising a sleeve 4, a plurality of sleeves 4 are arranged vertically outside the bottom end of the clamping plate 1, a top rod 5 movably sleeved with the sleeve 4 is arranged outside the top end of the clamping plate 2, a spring 6 is arranged at one end inside the sleeve 4, a movable disk 7 is fixedly installed at the other end of the spring 6, a slot 8 is arranged on the same side of the clamping plate 1 and the clamping plate 2, and the filter element 3 matches the slots 8 on both sides;

[0026] In this embodiment, when installing the filter element 3, through the cooperation of the sleeve 4, the push rod 5, the spring 6 and the movable disk 7, it is only necessary to place the clamping plate 1 and the clamping plate 2 corresponding to each other, so that the push rod 5 is inserted into the sleeve 4, and the quick positioning can be achieved under the action of the spring 6. In actual operation, the maintenance personnel or users do not need to use additional tools or perform complicated operating steps. The initial positioning of the clamping plate 1 and the clamping plate 2 can be completed by a simple pressing action, which greatly saves the installation time. Similarly, when disassembling the filter element 3 for replacement or cleaning, the clamping plate 1 and the clamping plate 2 can be easily separated, and the filter element 3 can be taken out conveniently and quickly.

[0027] like Figure 2 and Figure 5As shown, a locking mechanism is provided between the two sides of the clamping plate 1 and the clamping plate 2, and the locking mechanism includes a side strip 9, and the side strips 9 are provided at both ends of the middle part of the same side of the clamping plate 1 and the clamping plate 2, and a fixing strip 10 is provided on both sides of the middle part of the clamping plate 2 and close to the left side of the side strip 9, and a positioning hole 11 is provided at the end of the side strip 9, and a fixing block 12 is provided on the outer side of the side strip 9 and the fixing strip 10, and positioning rods 13 matching the positioning holes 11 are provided on both sides of the back of the fixing block 12, and the locking mechanism also includes an insert block 14, and a rectangular groove 15 matching the insert block 14 is provided in the middle of the fixing strip 10, and the locking mechanism further includes a bolt 16, and the bolt 16 is movably provided in the middle of the front of the fixing block 12, and a threaded groove 17 is provided inwardly in the middle of the rectangular groove 15, and the end of the bolt 16 passes through the insert block 14 and is threadedly connected with the threaded groove 17;

[0028] In this embodiment, the locking mechanism makes the connection between the clamping plate 1 and the clamping plate 2 more stable through the mutual cooperation of the side strip 9, the fixing strip 10, the fixing block 12, the positioning rod 13, the plug block 14 and the bolt 16. The positioning rod 13 is inserted into the positioning hole 11 of the side strip 9 to achieve the preliminary positioning of the fixing block 12 and the side strip 9. The plug block 14 is inserted into the rectangular groove 15 of the fixing strip 10 to further limit the relative movement of the clamping plate 1 and the clamping plate 2. Finally, the plug block 14 is tightly connected to the fixing strip 10 by the bolt 16. The connection method of coordinated cooperation of multiple components can effectively prevent the clamping plate from loosening due to vibration, bumps and other factors during the driving of the car, thereby ensuring the structural stability of the entire air filter device.

[0029] Working principle: When the filter element 3 needs to be installed, first place the filter element 3 at a suitable position on the inner side of the second clamp plate 2, so that the filter element 3 matches the slot 8 on one side of the second clamp plate 2, and then place the first clamp plate 1 just above the top of the second clamp plate 2, so that the sleeve 4 on the first clamp plate 1 corresponds to the push rod 5 on the second clamp plate 2. At this time, press the first clamp plate 1 downward, and the push rod 5 will gradually insert into the sleeve 4. The push rod 5 will squeeze the movable disk 7 during the insertion process. After being squeezed, the movable disk 7 will compress the spring 6. The spring 6 will produce elastic deformation during the compression process to store a certain amount of elastic potential energy, and the filter element 3 is clamped between the inner sides of the first clamp plate 1 and the second clamp plate 2. After the clamping plates 1 and 2 clamp the filter element 3, the positioning hole 11 and the rectangular groove 15 are on the same horizontal line, and then the fixing block 12 is placed on the outside of the side strip 9 and the fixing strip 10, so that the positioning rods 13 on both sides of the back of the fixing block 12 are inserted into the positioning holes 11 at the end of the side strip 9, to achieve the initial positioning of the fixing block 12 on the side strip 9, and the insert block 14 is inserted into the rectangular groove 15 in the middle of the fixing strip 10, so that the insert block 14 matches the rectangular groove 15, and the relative movement between the clamping plates 1 and 2 is further restricted, and the bolt 16 movably arranged in the middle of the front side of the fixing block 12 is passed through the insert block 14 and is threadedly connected with the threaded groove 17 arranged inwardly in the middle of the rectangular groove 15. During the process of tightening the bolt 16, the bolt 16 will gradually penetrate into the thread groove 17, making the connection between the fixing block 12, the insert block 14 and the fixing strip 10 tighter, thereby firmly connecting the clamping plate 1 and the clamping plate 2 together to prevent the clamping plate from loosening due to vibration and other factors during the driving of the car, thereby ensuring the fixing effect and filtering efficiency of the filter element 3.
