DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0028] The embodiment of the present invention provides a vehicle air conditioning filter replacement device and an operating method thereof, including a filter frame 1 and an air conditioning filter 2. For example, Figure 1-Figure 5 shown.

[0029] A first connecting groove 31 is provided on the inner side of the filter element frame 1, a connecting plate 32 is fixedly connected to one side of the air conditioning filter element 2, and the connecting plate 32 is slidably connected to the inner side of the first connecting groove 31. A hollow groove 6 is provided on the lower side of the filter element frame 1, and a replacement mechanism 4 is provided between the filter element frame 1 and the connecting plate 32.

[0030] The replacement mechanism 4 includes a pull rod 41 slidably connected to the inner side of the filter element frame 1, a mounting groove 42 is provided on the inner side of the filter element frame 1, and the mounting groove 42 is communicated with the first connecting groove 31, the pull rod 41 is slidably connected to the inner side of the mounting groove 42 and the hollow groove 6, and a return spring 43, a pushing spring 46 and a limiting plate 47 are fixedly connected to the inner side of the filter element frame 1, the return spring 43 is arranged on the inner side of the mounting groove 42, and a clamping block 44 is fixedly connected to the upper end of the return spring 43, a clamping groove 45 is provided on the lower side of the connecting plate 32, and the clamping block 44 is movably clamped on the inner side of the clamping groove 45, the pushing spring 46 and the limiting plate 47 are both arranged on the inner side of the first connecting groove 31, and the limiting plate 47 is arranged between the connecting plate 32 and the air conditioning filter element 2.

[0031] One end of the pushing spring 46 is fixedly connected to a fixing plate 81 , and one side of the fixing plate 81 is fixedly connected to a first limiting rod 82 . The first limiting rod 82 is disposed on the inner side of the pushing spring 46 .

[0032] Specifically, the filter element frame 1 can be connected to the connecting plate 32 through the first connecting groove 31, and the connecting plate 32 and the air conditioning filter element 2 are connected, so that the air conditioning filter element 2 can be installed, so that the air conditioning filter element 2 can be used smoothly. The filter element frame 1 can be connected to the pull rod 41 through the hollow groove 6 and the installation groove 42. The reset spring 43 can reset the block 44 after being squeezed while connecting to the block 44. At the same time, the pull rod 41 can limit the reset spring 43 to reduce the possibility of bending of the reset spring 43 when it is stretched.

[0033] In addition, the block 44 can limit the connection plate 32 through the slot 45, so as to realize the installation and restriction of the connection plate 32 and the air conditioning filter element 2, and the hollow groove 6 can facilitate people to pull the pull rod 41, and when the pull rod 41 is pulled, it will drive the block 44 to move downward, so that the block 44 moves out from the inner side of the slot 45, and the limit reset spring 43;

[0034] In addition, after the connecting plate 32 is installed to the inner side of the filter element frame 1, the pushing spring 46 will be squeezed. When the block 44 no longer limits the slot 45, the pushing spring 46 can use its own elasticity to pop out the connecting plate 32 and the air-conditioning filter element 2, thereby realizing the disassembly of the air-conditioning filter element 2 and facilitating the replacement of the air-conditioning filter element 2. At the same time, the limiting plate 47 can limit the extension and contraction of the pushing spring 46, thereby reducing the possibility of deformation of the pushing spring 46 during extension and contraction.

[0035] The inner side of the connecting plate 32 is fixedly connected with a rubber filling block 7. Figure 2-Figure 6 shown.

[0036] The rubber filling block 7 is arranged on the inner side of the slot 45, and the rubber filling block 7 is arranged on the outer side of the block 44. A reciprocating spring 91 is fixedly connected to the inner side of the filter element frame 1, and a movable plate 92 is fixedly connected to one end of the reciprocating spring 91. A disturbance plate 93 is fixedly connected to the upper side of the movable plate 92, and a plurality of disturbance plates 93 are arranged, and the disturbance plate 93 is arranged on the lower side of the air conditioning filter element 2.

[0037] A second limit plate 10 is fixedly connected to the inner side of the filter element frame 1 . The second limit plate 10 is arranged on the inner side of the reciprocating spring 91 and the movable plate 92 . The movable plate 92 is slidably connected to the outer side of the second limit plate 10 .

[0038] Specifically, the rubber filling block 7 can be used to fill the gap between the card block 44 and the card slot 45, so that the connection between the connecting plate 32 and the card block 44 can be more tightly connected, and the connecting plate 32 is not easy to shake when in use;

[0039] In addition, the filter element frame 1 can connect the movable plate 92 and the disturbance plate 93 through the reciprocating spring 91. After people push the movable plate 92, the reciprocating spring 91 can be squeezed by itself, and drive the movable plate 92 to reset, so as to realize the reciprocating movement of the disturbance plate 93, so that the disturbance plate 93 can smoothly disturb the air conditioning filter element 2, and make the leaves and other debris fall to the inner side of the air conditioning filter element 2, which is convenient for subsequent removal;

[0040] In addition, the second limiting plate 10 can limit the extension and contraction of the reciprocating spring 91 and the sliding of the movable plate 92, thereby reducing the possibility of bending of the reciprocating spring 91 when it is extended and contracted, and increasing the stability of the movable plate 92 when it is sliding.

[0041] The upper side of the filter element frame 1 is provided with a second connecting groove 121. Figure 1-Figure 6 shown.

[0042] A first connecting rod 122 is fixedly connected to the inner side of the filter element frame 1, and the first connecting rod 122 is arranged on the inner side of the second connecting groove 121. A shielding plastic sheet 123 is fixedly connected to the outer side of the first connecting rod 122, and a second connecting rod 124 is fixedly connected to the side of the shielding plastic sheet 123 away from the first connecting rod 122.

[0043] A slot 131 is provided on the upper side of the filter element frame 1 , and an insert block 132 is fixedly connected to the outer side of the second connecting rod 124 . The insert block 132 is movably inserted into the inner side of the slot 131 .

[0044] A limiting block 11 is fixedly connected to the inner side of the filter element frame 1 . The limiting block 11 is arranged on the lower side of the air conditioning filter element 2 . The limiting block 11 is arranged on one side of the moving plate 92 .

[0045] Specifically, the filter element frame 1 can be connected to the first connecting rod 122 through the second connecting groove 121, and the shielding plastic sheet 123 can shield the upper side of the air conditioning filter element 2 to a certain extent, so that when people pop out the air conditioning filter element 2 from the inner side of the filter element frame 1, the dust generated when the air conditioning filter element 2 is ejected is not easy to float into the air in large quantities, thereby reducing the situation where people inhale a large amount of dust;

[0046] In addition, the second connecting rod 124 can be connected to the plug block 132. After the plug block 132 is connected to the inner side of the slot 131, people do not need to manually pull the second connecting rod 124 when using the shielding plastic sheet 123.

[0047] In addition, the limiting block 11 can play a certain limiting role on the movable plate 92, so that the movable plate 92 is not easy to slide out from the inner side of the filter element frame 1 due to the shaking of the vehicle when not in use.

[0048] A vehicle air-conditioning filter replacement device and an operating method thereof are proposed by an embodiment of the present invention, and their working principles are as follows: when the device is in use, the staff can remove the used air-conditioning filter 2 from the inner side of the filter frame 1. When removing it, the second connecting rod 124 can be first removed from the inner side of the second connecting groove 121, and the plug 132 can be plugged into the inner side of the slot 131 to block dust. Then, the pull rod 41 can be pulled. After the pull rod 41 drives the block 44 to move down to a certain distance, the block 44 will move out from the inner side of the slot 45. At this time, the pushing spring 46 can push the air-conditioning filter 2 through its own elasticity, so that the air-conditioning filter 2 pops out from the inner side of the filter frame 1. If the air-conditioning filter 2 is not completely popped out, people can pour out the air-conditioning filter 2 by turning one side of the air-conditioning filter 2 downward.

[0049] When it is necessary to install a new air-conditioning filter element 2, people can align the connecting plate 32 with the first connecting groove 31, and push the connecting plate 32 after alignment. When the connecting plate 32 slides on the inner side of the first connecting groove 31, it will squeeze the pushing spring 46, and after moving to a certain distance, it will squeeze the block 44, and the block 44 will move downward due to the squeezing force. Thereafter, when the connecting plate 32 is fully inserted into the inner side of the first connecting groove 31, the block 44 can be reset by the elasticity of the reset spring 43, and be snapped to the inner side of the slot 45, thereby realizing the installation of the new air-conditioning filter element 2. At the same time, the squeezing of the pushing spring 46 can also facilitate the next replacement of the air-conditioning filter element 2.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
