DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-Figure 3 As shown, a filter device for convenient installation of filter bags includes a device connection end 1, a support component 3 and a mounting component 4. A slide groove 2 is opened inside the device connection end 1, and the support component 3 is penetrated on the left side of the device connection end 1. The support component 3 includes a left spring rod 301, a force plate 302 and a left hook 303. The right end of the left spring rod 301 is connected to the force plate 302, and the left end of the left spring rod 301 is connected to the left hook 303. The mounting component 4 is slidably connected to the inner side of the slide groove 2. The installation assembly 4 includes a plug plate 401, a placement hole 402, a filter bag body 403, a bag side hook 404, a spring strut 405 and a right hook 406. The middle surface of the plug plate 401 is provided with a placement hole 402, and the filter bag body 403 is penetrated inside the placement hole 402. The filter bag body 403 is provided with bag side hooks 404 on both sides. The spring struts 405 are penetrated inside the two sides of the plug plate 401, and the right end of the spring strut 405 is connected to the right hook 406;

[0023] The specific operation is as follows: when replacing and installing the filter bag body 403, the filter bag body 403 is passed through the placement hole 402, and the bag side hooks 404 on both sides of the filter bag body 403 are manually hooked with the right hook piece 406 and the left hook piece 303, and then the plug plate 401 is inserted into the slide groove 2. During the insertion process, the left end of the spring support rod 405 contacts the left side of the inside of the device connection end 1, so that the spring support rod 405 is shifted to the right in disguise and extends from the right side of the plug plate 401, so that the right hook piece 406 carries the filter bag body The right side of the filter bag body 403 moves to the right, and at the same time, the force-bearing plate 302 on the right side of the left spring rod 301 is subjected to the force of the plug plate 401 moving to the left, so that the left spring rod 301 moves to the left and extends from the left side of the device connection end 1, so that the left hook 303 carries the left side of the filter bag body 403 to move to the left, thereby when the plug plate 401 carries the filter bag body 403 and inserts it into the slide groove 2 to complete the insertion, the closed part of the lower part of the filter bag body 403 can be pulled open, so that the internal space of the filter bag body 403 can be expanded.

[0024] like Figure 1-Figure 3As shown, at least two bag side hooks 404 are provided, and the bag side hooks 404 are symmetrically distributed about the central axis of the filter bag body 403, the left hook 303 is elastically connected to the device connection end 1 through the left spring rod 301, and the left hook 303 is hooked with the bag side hook 404 on the left side of the filter bag body 403, the right hook 406 is elastically connected to the plug plate 401 through the spring support rod 405, and the right hook 406 is hooked with the bag side hook 404 on the right side of the filter bag body 403, the plug plate 401 is slidably connected to the device connection end 1 through the slide groove 2, and the bottom of the device connection end 1 is a hollow structure, the left end of the spring support rod 405 is in contact with the left side of the inner wall of the device connection end 1, and the left side of the inner wall of the device connection end 1 is a "concave"-shaped structure;

[0025] The specific operation is as follows: after the filter bag body 403 is inserted into the placement hole 402 on the surface of the plug plate 401, the installation of the filter bag body 403 can be completed by simply inserting the plug plate 401 into the chute 2. The installation method is simple to operate. When the plug plate 401 is inserted into the chute 2, the left hook 303 and the right hook 406 are pre-connected with the bag side hooks 404 on both sides of the filter bag body 403. During the insertion of the plug plate 401, the spring support rod 405 and the left spring rod 301 make the left hook 303 and the right hook 406 carry the two sides of the filter bag body 403 away from each other, and pull the filter bag body 403 open to expand its internal space for better use;

[0026] Among them, the number of bag side hooks 404 is at least two and there is no upper limit. The specific number needs to be configured according to the size of the filter bag body 403. When the number of corresponding bag side hooks 404 increases, the end length of the left hook 303 and the right hook 406 may be extended to ensure that the left hook 303 and the right hook 406 can hook all the bag side hooks 404.

[0027] like Figure 1-Figure 3 As shown, through holes 5 are provided on both sides of the upper surface of the device connection end 1, and elastic plug blocks 6 are embedded on both sides of the surface of the plug plate 401. The elastic plug blocks 6 are elastically connected to the plug plate 401, and the outer opening size of the elastic plug block 6 is adapted to the inner opening size of the through hole 5;

[0028] The specific operation is as follows: when the plug plate 401 carries the filter bag body 403 and is inserted into the slide groove 2, the elastic plug block 6 first contacts the top of the inner wall of the device connection end 1. At this time, the elastic plug block 6 is in a compressed structure. After the elastic plug block 6 coincides with the perforation 5, the elastic plug block 6 is lifted up and reset to pass through the perforation 5, so that the plug plate 401 is engaged with the device connection end 1, thereby preventing the plug plate 401 from loosening or moving outward for no reason. When the filter bag body 403 needs to be replaced later, the filter bag body 403 can be replaced by simply pressing down the elastic plug block 6 and pulling out the plug plate 401, thereby facilitating the replacement and installation of the filter bag body 403.

[0029] In summary, if Figure 1-Figure 3 As shown, the filter device for convenient installation of filter bags, when in use, first when replacing and installing the filter bag body 403, the filter bag body 403 is passed through the placement hole 402, and the bag side hooks 404 on both sides of the filter bag body 403 are manually hooked with the right hook piece 406 and the left hook piece 303;

[0030] Then, the plug plate 401 is inserted into the chute 2. During the insertion process, the left end of the spring support rod 405 contacts the left side of the device connection end 1, so that the spring support rod 405 moves rightward in disguise and extends from the right side of the plug plate 401, so that the right hook 406 carries the right side of the filter bag body 403 to move rightward. At the same time, the force-bearing plate 302 on the right side of the left spring rod 301 is subjected to the force of the plug plate 401 moving leftward, so that the left spring rod 301 moves leftward and extends from the left side of the device connection end 1, so that the left hook 303 carries the left side of the filter bag body 403 to move leftward. Therefore, when the plug plate 401 carries the filter bag body 403 and inserts it into the chute 2 to complete the insertion, the closed part of the lower part of the filter bag body 403 can be pulled open, so that the internal space of the filter bag body 403 can be expanded.

[0031] When the plug plate 401 carrying the filter bag body 403 is inserted into the chute 2, the elastic plug block 6 first contacts the top of the inner wall of the device connection end 1. At this time, the elastic plug block 6 is in a compressed structure. After the elastic plug block 6 coincides with the through hole 5, the elastic plug block 6 is lifted up and reset to pass through the through hole 5, so that the plug plate 401 is engaged with the device connection end 1, thereby preventing the plug plate 401 from loosening or moving outward for no reason. When the filter bag body 403 needs to be replaced later, the filter bag body 403 can be replaced by simply pressing down the elastic plug block 6 and pulling out the plug plate 401.
