Detailed Implementation

[0029] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example: An easily removable air conditioner filter, referring to Figures 1-5, includes,

[0032] The air conditioner body 100 includes a housing 110, a push-pull block 120 disposed on the outside of the housing 110, a filter screen 130 fixedly connected to the outer surface of the push-pull block 120, and a fresh air inlet 140 connected to the bottom of the housing 110.

[0033] It should be noted that the outer casing 110 is the main frame of the air conditioner body 100, which is used to provide installation support for internal components. The push-pull block 120 allows the user to manually push and pull the filter 130. The filter 130 is used to intercept dust and impurities in the air to ensure the cleanliness of the air outlet of the air conditioner body 100. The fresh air inlet 140 is used to introduce external air. After being filtered by the filter 130, the external air enters the interior of the air conditioner body 100, and is then processed and blown out by the internal system of the air conditioner body 100. The air conditioner body 100 is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0034] The disassembly and assembly mechanism 200 includes a positioning component 210 for initially positioning the filter screen 130 inside the housing 110, a snap-fit ​​component 220 for fixing the positioned filter screen 130, and a locking component 230 for preventing the snap-fit ​​component 220 from loosening.

[0035] The positioning component 210 is located on the outside of the filter screen 130, the snap-fit ​​component 220 is located on the outer surface of the housing 110, and the locking component 230 is located on the outer surface of the snap-fit ​​component 220.

[0036] The positioning component 210 includes a fixing plate 211 fixedly connected to the outer surface of the filter screen 130, a perforated plate 212 fixedly installed inside the fixing plate 211, and a plug groove 213 penetrating the surface of the housing 110 and used in conjunction with the fixing plate 211.

[0037] It should be noted that the shape of the fixing plate 211 matches the insertion slot 213. After the fixing plate 211 is inserted into the insertion slot 213, it can restrict the longitudinal movement of the filter screen 130, so that the filter screen 130 can only move horizontally. The perforated plate 212 is used to cooperate with the snap-fit ​​assembly 220 to restrict the horizontal movement of the filter screen 130, so as to ensure the positional stability of the filter screen 130.

[0038] Specifically, the filter screen 130 is inserted into the inner wall of the outer casing 110, and the fixing plate 211 is inserted into the inner wall of the insertion slot 213.

[0039] Furthermore, the snap-fit ​​assembly 220 includes a fixed sleeve 221 fixedly installed on the outer surface of the housing 110, a rotating rod 222 rotatably connected to the inner surface of the fixed sleeve 221, a threaded rod 223 fixedly connected to the outer end face of the rotating rod 222, and an internally threaded post 224 threadedly connected to the outer surface of the threaded rod 223.

[0040] Preferably, the snap-fit ​​assembly 220 also includes a plurality of levers 225 hinged to the inner surface of the internal threaded post 224, and a snap hook 226 integrally formed on the outer end face of the lever 225 and used in conjunction with the insertion slot 213.

[0041] It should be further explained that the fixed sleeve 221 is used to support the various components of the snap-fit ​​assembly 220 to ensure the stable operation of each component. When the rotating rod 222 is rotated, it can drive the threaded rod 223 to rotate synchronously, so that the threaded rod 223 drives the internal threaded column 224 to move vertically axially. Then, the internal threaded column 224 drives the swing rod 225 and the hook 226 to move synchronously. When the inclined surface of the hook 226 moves to the position of contacting the inner wall of the perforated plate 212, it will be squeezed by the inner wall of the perforated plate 212, so that the hook 226 drives the swing rod 225 to swing. Then, the swing rod 225 stretches the first spring 227. When the plane of the hook 226 moves to the position of contacting the bottom of the perforated plate 212, the reaction force of the first spring 227 drives the swing rod 225 and the hook 226 to return to the original position, so that the hook 226 engages with the perforated plate 212.

[0042] It should be noted that the snap-fit ​​assembly 220 also includes a first spring 227 fixedly installed on the outside of the rocker arm 225, a guide block 228 fixedly connected to the outer surface of the internal thread post 224, and a guide groove 229 penetrating the surface of the fixed sleeve 221 and used in conjunction with the guide block 228.

[0043] Furthermore, the outer end face of the hook 226 is fixedly connected to the inner wall of the fixed sleeve 221, and the outer surface of the guide block 228 slides in contact with the inner wall of the guide groove 229.

[0044] Specifically, the locking assembly 230 includes a ratchet 231 fixedly sleeved on the outer surface of the rotating rod 222, a pawl 232 engaged with the outer surface of the ratchet 231, and a second spring 233 fixedly installed on the outer surface of the fixed sleeve 221 and used in conjunction with the pawl 232.

[0045] The ratchet 231 can rotate synchronously with the rotating rod 222 and engage with the pawl 232 through its toothed structure. Under the elastic force of the second spring 233, the pawl 232 can always press against the ratchet 231 to prevent the ratchet 231 from rotating in the opposite direction, thereby locking the rotating rod 222 to ensure that the locking assembly 220 remains in the locked state.

[0046] Preferably, the outer end face of the pawl 232 is fixedly mounted on the top of the fixed sleeve 221 by a bearing, and the outer end face of the second spring 233 abuts against the outer surface of the pawl 232.

[0047] When using,

[0048] Push the push-pull block 120 to insert the filter screen 130 along the inner wall of the outer shell 110, so that the fixing plate 211 is aligned and inserted into the insertion slot 213, and the filter screen 130 is initially positioned. At this time, the control plate 212 is aligned with the center of the fixing plate 211, and the filter screen 130 can only move horizontally.

[0049] Then rotate the rotating rod 222 to drive the threaded rod 223 to rotate, driving the internal threaded column 224 and the guide block 228 to move vertically downward along the guide groove 229. At the same time, the internal threaded column 224 drives the hook 226 to extend out of the fixed sleeve 221 through the swing rod 225.

[0050] When the inclined surface of the hook 226 contacts the inner wall of the hole plate 212: the hook 226 will be squeezed and drive the rocker arm 225 to swing, and the first spring 227 will be stretched by the rocker arm 225;

[0051] When the hook 226 continues to move until its plane contacts the bottom of the perforated plate 212, the reaction force of the first spring 227 drives the swing rod 225 and the hook 226 to return to their original positions, so that the hook 226 engages with the perforated plate 212, thus completing the fixation of the filter screen 130.

[0052] During this process: the ratchet 231 rotates synchronously with the rotating rod 222, and the pawl 232, under the action of the second spring 233, always presses against the ratchet 231 to prevent it from rotating in the opposite direction, locking the rotating rod 222 and ensuring that the locking assembly 220 remains in the locked state.

[0053] Outside air enters through the fresh air inlet 140, is filtered by the filter 130, enters the air conditioner body 100, is then processed by the internal system and blown out.

[0054] When disassembling the filter screen 130, manually release the ratchet 232 to unlock the ratchet 231, and apply inward pressure to the hook 226 to prevent it from being blocked by the control plate 212. Then, rotate the lever 222 in the opposite direction to drive the internal threaded post 224, the rocker arm 225 and the hook 226 to move in the opposite direction until the hook 226 disengages from the orifice plate 212. Then, pull the push-pull block 120 to pull the filter screen 130 out of the housing 110.

[0055] In summary, by setting up the disassembly and assembly mechanism 200, not only can the longitudinal and horizontal movement of the air conditioner filter 130 be precisely restricted by the snap-fit ​​component 220 during the installation and disassembly of the air conditioner filter 130, but the locking component 230 can also be used to prevent the snap-fit ​​component 220 from loosening due to vibration of the air conditioner body 100 or external force. This achieves the effect of completing the disassembly and assembly of the filter 130 without tools while ensuring the connection stability of the filter 130.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
