Description

Technical Field

[0001] The utility model belongs to the field of filter elements, and in particular relates to a 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 filter element locking mechanism, which is based on the contact bevel matching arrangement 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 filter element locking mechanism of the utility model includes a filter element seat provided with a button slider and a push rod that abuts against the end of the button slider; the end surface of the button slider is an inclined surface, and the end surface of the push rod abutting against the button slider is an inclined surface, so that the push rod can vertically push and squeeze the button slider to slide left and right.

[0007] Furthermore, a water flow passage is provided in the filter element seat of the filter element locking mechanism, and a locking device is provided on the filter element seat to achieve a detachable connection between the filter element and the filter element. The locking device includes a slide fixing cover installed at the bottom end of the filter element seat and having a central through hole.

[0008] Furthermore, the button slider of the filter element locking mechanism has a central through hole and is fixed between the filter element seat and the slide plate fixing cover in a manner that allows it to slide back and forth.

[0009] 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 the connection and separation of the filter element and the filter element seat are achieved through the cooperation of the protrusion and the groove.

[0010] Furthermore, fixing cover grooves for the protrusions to pass through are provided on both sides of the central through hole of the slide fixing cover of the filter element locking mechanism.

[0011] Furthermore, the other end of the button slider of the filter element locking mechanism is connected to an elastic element, and the other end of the elastic element is against the inner wall of the filter element seat.

[0012] Beneficial effect: Compared with the prior art, the advantages of the present invention are as follows: the filter element locking mechanism is configured with a button slider end face and a push rod end face both having inclined surfaces, so that the inclined surfaces of the push rod and the button slider are against or in contact with each other, and then in the vertical pushing process of the push rod, the inclined surface of the push rod is pushed to squeeze the button to slide left and right, and finally the filter element and the filter element seat are locked and unlocked conveniently.

[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 4As shown, the locking device includes a slide fixing cover 5 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 5 and the filter element seat 2 in a manner that can slide back and forth. Both the slide fixing cover 5 and the button slider 1 are provided with a central through hole for the filter element to pass through. A plurality of grooves 6 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 7 corresponding to the plurality of grooves 6, and the surface where the grooves 6 meet the protrusions 7 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 7 and the grooves 6. Fixed cover grooves 8 for the protrusions 7 to pass through are provided on both sides of the central through hole of the slide fixing cover 5.

[0021] The tail end of button slider 1 is connected to an elastic element 9, the other end of which abuts against the inner wall of filter cartridge holder 2. The top end of button slider 1 extends beyond filter cartridge holder 2 and engages with push rod 3. The top end of button slider 1, where it contacts push rod 3, is inclined. Similarly, the end end of push rod 3, where it contacts button slider 1, is also inclined. This means that the contact surfaces of button slider 1 and push rod 3 form an inclined contact. As push rod 3 moves vertically, the inclined surface of push rod 3 compresses the inclined surface of button slider 1, pushing button slider 1 back and forth, creating a sliding motion.

[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 3 is pushed upward, and the vertical movement of the push rod 3 drives the button slider 1 to slide backward, so that the groove 6 on the button slider 1 is connected with the fixing cover groove 8 to form a passage, and the filter element is replaced.
