Description

Technical Field

[0001] The utility model belongs to the field of filter elements, and in particular relates to a push-type filter element locking mechanism. Background Art

[0002] Currently, filtration devices are widely used, especially in the huge market for water purification and drinking water equipment. With the development of science and technology, more and more filtration devices and other products have emerged. The filter element is the core of the filtration device. The filter element needs to be replaced, repaired or cleaned after a period of use. This requires removing the filter part of the filter element from the filtration device. Currently, the filter element is mostly fixed with connectors, rotating snap connections, and threaded connections. Therefore, it is inconvenient to install and requires tools, the installation torque is large, and the water supply or water outlet cannot be automatically disconnected. Each replacement requires manual switching of the water supply locking device, and water leaks when the filter element is inverted or horizontal. These problems make the removal of the filter element inefficient, time-consuming and labor-intensive, and the connectors are easy to lose, making it difficult for non-professionals to operate.

[0003] Existing technologies such as announcement number CN108686414B, entitled "A device for conveniently replacing filter cartridges", disclose the use of a connecting rod drive method to achieve convenient replacement of filter cartridges, but it adopts a concave slope set on the connecting rod to lock and unlock the filter cartridge and the filter cartridge seat through the base of the slope and the button slider.

[0004] Based on this, there is an urgent need for another filter element locking mechanism that can also easily replace or disassemble the filter element. Utility Model Content

[0005] Purpose of the utility model: The technical problem to be solved by the utility model is to provide a push-type filter element locking mechanism, which is based on the cooperation between the push rod of the filter element device and the locking device, so that the filter element can be easily replaced and disassembled.

[0006] Technical solution: The push-type filter element locking mechanism of the utility model includes a filter element seat provided with a button slider, a rotating block rotatably arranged on the filter element seat and forming an inclined surface against the end of the button slider, and a push rod against the rotating block. The push rod moves vertically to push the rotating block to rotate and then drives the button slider to slide back and forth, thereby realizing locking and unlocking of the filter element.

[0007] Furthermore, a connecting rod is horizontally provided on the filter element seat of the filter element locking mechanism to realize the rotation connection of the rotating block, and the rotating block is rotatably provided on the connecting rod.

[0008] Furthermore, the rotating block of the filter element locking mechanism is a polygonal structure, and its end surface that abuts against the button slider is an inclined surface.

[0009] Furthermore, a passage for water flow is provided in the filter cartridge seat of the filter cartridge locking mechanism, and a locking device is provided on the filter cartridge seat to realize a detachable connection between the filter cartridge seat and the filter cartridge, and the locking device includes a slide plate fixing cover installed at the bottom end of the filter cartridge seat and having a central through hole, the button slider has a central through hole and is fixed between the filter cartridge seat and the slide plate fixing cover in a manner that can slide back and forth, and the other end of the button slider is connected to an elastic element.

[0010] Furthermore, grooves are provided on both sides of the central through hole of the button slider of the filter element locking mechanism, and a protrusion corresponding to the groove is provided at the upper end of the filter element. The surface of the groove that contacts the protrusion is an inclined surface, and is connected to and separated from the filter element seat through the cooperation of the protrusion and the groove; fixing cover grooves for the protrusion to pass through are provided on both sides of the central through hole of the slide plate fixing cover.

[0011] Furthermore, hooks are provided on both sides of the push rod extending from the filter element seat of the filter element locking mechanism, and the connecting rod spans the hooks on both sides.

[0012] Beneficial effect: Compared with the prior art, the advantages of the present invention are as follows: the filter element locking mechanism realizes the rotation of the rotating block by setting a rotating block and combining the linkage between the push rod and the button slider during the vertical pushing process of the push rod, and then realizes the left and right sliding of the button through the inclined contact between the rotating block and the button slider, and finally achieves the convenient locking and unlocking of the filter element and the filter element seat.

[0019] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the push-type filter element locking mechanism of the present invention includes a filter element seat 2 with a water flow passage provided therein, and a locking device that realizes the connection between the filter element seat 2 and the filter element in a detachable manner. Figures 2 to 4 As shown, the locking device includes a slide fixing cover 6 provided at the bottom end of the filter element seat 2 and having a central through hole, and a button slider 1 fixed between the slide fixing cover 6 and the filter element seat 2 in a manner that can slide back and forth. Both the slide fixing cover 6 and the button slider 1 are provided with a central through hole for the filter element to pass through. A plurality of grooves 8 are provided on both sides of the central through hole of the button slider 1. The upper end of the filter element is provided with a plurality of protrusions 11 corresponding to the plurality of grooves 8, and the surface where the grooves 8 meet the protrusions 11 is an inclined surface, and the connection and separation between the filter element and the filter element seat 2 are achieved by the cooperation between the protrusions 11 and the grooves 8. Fixed cover grooves 9 for the protrusions 11 to pass through are provided on both sides of the central through hole of the slide fixing cover 6.

[0021] The tail end of the button slider 1 is connected to an elastic element 7, while the top end of the button slider 1 extends out of the filter cartridge seat 2 and is linked to the push rod 4 through a rotating block 3. That is, the push-type filter cartridge locking mechanism also includes a rotating block 3 that abuts against the top end of the button slider 1. The rotating block 3 can be rotatably mounted on the filter cartridge seat 2 via a connecting rod 5. The rotating block 3 can be a polygonal structure, and the contact surface between the rotating block 3 and the button slider 1 is an inclined surface. The bottom end of the rotating block 3 abuts against the push rod 4. That is, through the vertical movement of the push rod 4, the rotating block 3 is pushed to rotate around the connecting rod 5, and then the inclined surface abutting against the button slider 1 applies a horizontal force to the button slider 1 to drive the button slider 1 to slide left and right. Hooks 10 can be extended on both sides of the filter cartridge seat 2 on the push rod 4. The connecting rod 5 horizontally spans and runs through the hooks 10 on both sides to realize that the rotation of the rotating block 3 drives the button slider 1 to slide left and right.

[0022] Working principle: Figure 5 and Figure 6 As shown, when the filter element connected to the filter element seat 2 needs to be replaced or disassembled, the push rod 4 is pushed upward, and the vertical movement of the push rod 4 drives the rotating block 3 to rotate, and then based on the inclined contact between the rotating block 3 and the button slider 1, the button slider 1 is driven to slide backward, so that the groove 8 on the button slider 1 is connected with the fixed cover groove 9 to form a passage, and the filter element is replaced.
