Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water purifiers, in particular to a water purifier and a filter element clamping structure thereof. Background Art
[0002] The filter bottle is an important part of the water purifier. Different filter materials, such as PP cotton, activated carbon, ultrafiltration membrane or reverse osmosis membrane, etc., are installed in the filter bottle. These filter materials can remove harmful substances such as impurities, residual chlorine, peculiar smell, heavy metals, etc. in water, and provide cleaner and healthier drinking water. When installing the filter bottle, generally, a sealing ring or gasket of the filter bottle is installed on the filter bottle, and the filter bottle is inserted into the water purifier interface to ensure a tight connection.
[0003] In the existing market, for RO reverse osmosis water purifiers, in the design of the rotating buckle of the filter bottle, most are two-buckle rotating locking structures.

The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.
[0028] Below in conjunction with Figures 1 to 3 , the filter element clamping structure 100 provided by the embodiments of the present application will be described in detail through specific embodiments.
[0029] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the filter element clamping structure provided by the present utility model; Figure 2 which is a schematic structural diagram of the base of the filter element clamping structure provided by the present utility model; Figure 3 which is a schematic structural diagram of the filter element of the filter element clamping structure provided by the present utility model. The filter element clamping structure 100 provided by one embodiment of the present utility model includes a base 10 and a filter element 20. An installation port 11 is provided on the base 10, and a fixing groove 111 is provided on the installation port 11; the filter element 20 includes a head 21, a sealing ring 22 is provided on the outer side of the head 21, and a fixing part 211 is also provided on the outer side of the head 21; wherein, when the filter element 20 is arranged on the base 10, the head 21 is installed in the installation port 11 so that the fixing part 211 is received in the fixing groove 111.
[0030] The filter element 20 is fixed on the base 10 by installing the head 21 of the filter element 20 in the installation opening 11 of the base 10 and accommodating the fixing member 211 in the fixing groove 111. This clamping structure is relatively simple, and the filter element 20 is easy to install and remove, which is convenient for users to replace and maintain.
[0031] In addition, the sealing ring 22 of the head 21 follows the filter element 20 and enters the installation opening 11 of the base 10 at the same time. At this time, the filter element 20 can be prevented from moving up and down in the installation opening 11 of the base 10 due to its own gravity through the clamping connection between the fixing piece 211 and the fixing groove 111, thereby more effectively ensuring the sealing of the mating position between the sealing ring 22 of the filter element 20 and the installation opening 11 of the base 10, and solving the problem of water leakage at the mating position of the sealing ring 22 caused by the downward swing of the center of gravity of the filter element 20 when loading in a horizontal insertion manner.
[0032] In some embodiments, the fixing groove 111 is disposed on a side wall of the mounting opening 11 , and the base 10 is disposed on an outer peripheral side of the head 21 .
[0033] When the filter element 20 is installed on the base 10, the head 21 is first aligned with the installation opening 11 and inserted. As the head 21 is further inserted, the sealing ring 22 contacts the inner wall of the installation opening 11 to form a seal. At the same time, the fixing member 211 also enters the fixing groove 111 and is fixed in the fixing groove 111 by snapping or other means, thereby achieving the installation and fixing of the filter element 20. When removing the filter element 20, just apply appropriate force to pull the filter element 20 out of the installation opening 11.
[0034] By setting the base 10 on the outer peripheral side of the head 21 and setting the fixing groove 111 on the side wall of the installation opening 11, the installation of the filter element 20 can be made more convenient. It is only necessary to align the head 21 with the installation opening 11 and insert it, without the need for complicated alignment and fixing operations. Since the fixing member 211 is accommodated in the fixing groove 111, the cooperation between the fixing member 211 and the fixing groove 111 can provide better stability and prevent the filter element 20 from loosening or falling off during use. , thereby improving the connection stability and effectively preventing the relative movement of the filter element 20 and the base 10 from causing fluid leakage.
[0035] In some embodiments, a guide portion 112 is disposed on a side wall of the installation opening 11 , and the guide portion 112 is connected to a notch of the fixing groove 111 .
[0036] When installing the filter element 20, the head 21 of the filter element 20 will first come into contact with the guiding portion 112. The guiding portion 112 can guide the insertion direction of the filter element 20, making it easier to align with the installation opening 11 and the fixing groove 111. As the filter element 20 is further inserted, the fixing member 211 will slide along the guiding portion 112 into the fixing groove 111, thus completing the installation of the filter element 20. The setting of the guiding portion 112 can reduce the resistance and friction during the installation process, making the installation smoother. In addition, the guiding portion 112 can also play a certain sealing role. After the filter element 20 is installed in place, the guiding portion 112 can come into contact with the sealing ring 22 of the filter element 20, increasing the sealing area and further improving the sealing performance.
[0037] In some embodiments, the fixing member 211 includes a clamping portion 2111 and a connecting portion 2112. The connecting portion 2112 is connected to the clamping portion 2111, and the connecting portion 2112 is adapted to the fixing groove 111.
[0038] When installing the filter element 20, the clamping portion 2111 is guided by the guiding portion 112 into the fixing groove 111 of the installation opening 11. After the clamping portion 2111 is received in the fixing groove 111, at this time, the connecting portion 2112 abuts against the guiding portion 2113, thereby restricting the further movement of the clamping portion 2111 in the fixing groove 111. Through such a setting, the installation of the filter element 20 and the base 10 can be in place.
[0039] In some embodiments, a guiding portion 2113 is provided at one end of the clamping portion 2111 facing the fixing groove 111, and the guiding portion 2113 is inclined. Among them, the inclined surface of the guiding portion 2113 is parallel to the inclined surface of the guiding portion 112. When the filter element 20 enters the installation opening 11, the inclined surface of the guiding portion 2113 fits with the inclined surface of the guiding portion 112, making the installation smoother.
[0040] In some embodiments, three fixing members 211 are provided, and the three fixing members 211 are spaced apart on the outer peripheral side of the head 21 shown. Three fixing grooves 111 are provided, and the three fixing grooves 111 are spaced apart on the side wall of the installation opening 11, and the positions of the fixing grooves 111 correspond to the positions of the fixing members 211.
[0041] When installing the filter element 20, align the head 21 with the installation port 11 and insert it. The fixing member 211 will slide into the fixing groove 111 along the guiding portion 112. Since the position of the fixing groove 111 corresponds to the position of the fixing member 211, they will be accurately docked. The clamping portion 2111 will engage with the edge of the fixing groove 111, thereby realizing the fixation of the filter element 20. By providing three fixing members 211 on the outer peripheral side of the head 21 and providing a corresponding number of fixing grooves 111 on the side wall of the installation port 11, the connection points between the filter element 20 and the base 10 can be increased, the connection stability and reliability can be improved, and the filter element 20 can be prevented from loosening or falling off during use. The spaced arrangement of the three fixing members 211 and the fixing grooves 111 can make the force more uniform, distributed around the filter element 20, reduce local stress concentration, and thus extend the service life of the filter element 20. And more fixing points can provide a better sealing effect, ensure the reliable sealing between the filter element 20 and the base 10, and prevent fluid leakage.
[0042] Another embodiment of the present utility model further provides a water purifier, including a housing and the above-mentioned filter element clamping structure 100. The base 10 is disposed on the housing, and the filter element 20 is disposed in the housing and is clamped with the base 10.
[0043] Installing the head 21 of the filter element 20 in the installation port 11 of the base 10 and accommodating the fixing member 211 in the fixing groove 111 can realize the fixation of the filter element 20 on the base 10. This clamping structure is relatively simple, easy to install and disassemble the filter element 20, and convenient for users to replace and maintain.
[0044] Moreover, the sealing ring 22 of the head 21 enters the installation port 11 of the base 10 simultaneously with the filter element 20. At this time, through the clamping of the fixing member 211 and the fixing groove 111, the filter element 20 can be prevented from moving up and down in the installation port 11 of the base 10 due to its own gravity, thereby more effectively ensuring the sealing performance of the docking and matching position between the sealing ring 22 of the filter element 20 and the installation port 11 of the base 10, and solving the problem of water leakage at the matching position of the sealing ring 22 caused by the downward swing of the horizontal insertion loading center of the filter element 20.

It can be understood that the filter element clamping structure 100 provided by the embodiment of the present utility model further includes other structures for realizing the functions of the filter element clamping structure 100, which will not be elaborated herein one by one.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above.
