The locking plate 4 is annular and surrounds the connecting portion 11 in the assembled state. The locking plate 4 reciprocates vertically relative to the waterway plate 3 to lock or unlock the connecting portion 11.

[0036] The utility model provides a connection part 11 at one end of the filter element 1 to be plugged with the waterway plate 3 in the installation cavity 21 of the machine body 2, and provides a locking plate 4 to reciprocate vertically relative to the waterway plate 3, so as to achieve locking or unlocking of the connection part 11 by the locking plate 4; since the main force point of the filter element 1 is on the side when it is placed horizontally, the side of the filter element 1 is locked by providing a buckle structure. Therefore, the utility model ensures that the filter element 1 is installed horizontally and stably in the water purifier by double locking one end and the side of the filter element 1, and the locking structure is simple, the operation is convenient, and the filter element 1 is convenient to replace.

[0037] See also Figure 1 and Figure 4 In the present utility model, the filter element 1 includes a cylindrical filter element body 16 and an end cap 17. The filter element body 16 is arranged horizontally, the connection part 11 is arranged at one end of the filter element body 16, and the end cap 17 is arranged at the other end of the filter element body 16. The connection part 11 is a hexahedral structure and is arranged in the middle area of ​​one end of the filter element body 16. The connection part 11 is provided with three waterway interfaces, which are used for raw water, pure water and concentrated water to flow through respectively. The arrangement of the three waterway interfaces is not specifically limited and is arranged according to the waterway connection method of the water purification equipment.

[0038] The body 2 is provided with a cylindrical installation cavity 21 to adapt to the filter element 1 , and one end of the installation cavity 21 is provided with an installation position to install the waterway plate 3 , and the installation opening of the installation cavity 21 faces upward to facilitate the user to install, lock, unlock or remove the filter element 1 .

[0039] See also Figure 6The middle area of ​​the waterway plate 3 is recessed toward one end of the installation cavity 21 to form a receiving groove 31 with an opening toward the other end of the installation cavity 21. The receiving groove 31 is provided with a raw water inlet, a pure water outlet and a concentrated water outlet to be connected to the three waterway interfaces of the connection part 11 in the assembled state. Two side plates 32 are arranged in parallel and at intervals on the waterway plate 3. The two side plates 32 are arranged along the vertical movement direction of the locking plate 4, and the two side plates 32 extend from the end surface of the waterway plate 3 away from one end of the installation cavity 21 toward the other end of the installation cavity 21 to form a guide space for the vertical movement of the locking plate 4 between the two side plates 32, and the locking plate 4 is arranged in the guide space. The utility model forms a guide space between the two side plates 32 to limit the movement direction of the locking plate 4 to ensure the smooth locking or unlocking of the connection part 11.

[0040] Based on the above structure, see Figure 1 and Figure 4 The buckle structure includes a buckle 12 and a buckle hole 22 that are correspondingly arranged and adapted. The buckle 12 is arranged on the side of the filter element 1, and the buckle hole 22 is opened on the side wall of the installation cavity 21. During assembly, the filter element 1 is horizontally installed in the installation cavity 21, and the buckle 12 is locked in the buckle hole 22, so that the side of the filter element 1 and the body 2 are locked to prevent the filter element 1 from horizontally reciprocating relative to the body 2 along the extension direction of the installation cavity 21.

[0041] Since the point of gravity of the filter element 1 is concentrated at the bottom of the side, especially the middle area of ​​the bottom, when the filter element 1 is placed horizontally, the buckle 12 is preferably arranged in the middle of the side of the filter element 1 and at the bottom when it is placed horizontally to lock the filter element 1 more stably.

[0042] See also Figure 6 and Figure 7 The top of the locking plate 4 is provided with a pull-out portion 41, which extends upward to exceed the upper end of the waterway plate 3. The external force lifts the pull-out portion 41 upward to drive the locking plate 4 to move upward to achieve unlocking. In the utility model, the user can directly pull the locking plate 4 upward by hand through the pull-out portion 41.

[0043] The drawer portion 41 is provided with a drawer hole 42, and the drawer hole 42 horizontally penetrates the drawer portion 41. When the user pulls the locking plate 4 upward, the finger can be inserted into the drawer hole 42, so as to facilitate the upward pulling of the locking plate 4 and facilitate the use of force.

[0044] The downward movement of the locking plate 4 needs to be achieved with the help of other external forces. The locking plate 4 is elastically connected to the waterway plate 3 through the elastic member 5. The elastic member 5 is vertically arranged. When the connection part 11 is unlocked, the elastic member 5 is in a compressed state. When the elastic member 5 is in a natural state, the locking plate 4 locks the connection part 11. When the user pulls the locking plate 4 upward to the unlocked state, the elastic member 5 is compressed. Therefore, the utility model realizes the vertical reciprocating movement of the locking plate 4 with the help of the user's pulling force and the elastic force of the elastic member 5.

[0045] In the present invention, the elastic member 5 is a spring.

[0046] A filter element seat 6 is provided on one side of the waterway plate 3 facing away from one end of the installation cavity 21, and a locking plate 4 is provided between the waterway plate 3 and the filter element seat 6. The filter element seat 6 is provided with a guide groove 61 adapted to the connection portion 11, and the guide groove 61 is arranged horizontally opposite to the receiving groove 31. The guide groove 61 is provided in the middle area of ​​the filter element seat 6, and the central axis of the filter element seat 6, the waterway plate 3 and the filter element 1 are in a straight line to improve the stability of the installation of the filter element 1. During installation, the connection portion 11 passes through the locking plate 4 horizontally through the guide groove 61 and is inserted into the receiving groove 31.

[0047] On the one hand, the locking plate 4 is sandwiched between the filter element seat 6 and the waterway plate 3, so as to limit the locking plate 4 in the horizontal installation direction through the filter element seat 6 and the waterway plate 3. On the other hand, the connecting portion 11 is connected to the waterway plate 3 through the guide groove 61 of the filter element seat 6, which can improve the accuracy and stability of the plugging of the connecting portion 11 and the receiving groove 31. Therefore, the setting of the filter element seat 6 can improve the stability of the installation of the filter element 1.

[0048] The filter element seat 1 is a semi-enclosed structure with an opening toward the other end of the installation cavity 21 and is adapted to one end of the filter element 1. A clamping protrusion 18 is protruded outwardly from the side wall of one end of the filter element 1, and the filter element seat 6 is provided with a matching clamping groove 63 corresponding to the clamping protrusion 18. Specifically, the semi-enclosed structure of the filter element seat 6 is a cylindrical structure with an opening toward the other end of the installation cavity 21 to enclose one end of the filter element body 16, thereby improving the stability of the connection between the filter element 1 and the waterway plate 3. The clamping protrusion 18 is provided on the side wall of one end of the filter element body 16, and the clamping structure of the clamping protrusion 18 and the clamping groove 63 can prevent the filter element 1 from rotating relative to the filter element seat 6, thereby further improving the stability of the installation of the filter element 1.

[0049] On the basis of the above structure, at least one limit block 13 is provided on the vertically extending side of the connection part 11, the inner wall of the locking plate 4 is concave to form an unlocking channel 43 for the limit block 13 to pass through, and the groove wall of the guide groove 61 is concave to form a guide channel 62 for the limit block 13 to pass through, and the number of unlocking channels 43 and the number of guide channels 62 are equal to the number of limit blocks 13. In the assembled state, the guide channel 62 is horizontally arranged relative to the corresponding limit block 13, and the locking plate 4 reciprocates vertically relative to the waterway plate 3 so that the corresponding unlocking channel 43 and the limit block 13 are horizontally arranged relative to each other or horizontally misaligned, thereby unlocking or locking the connection part 11. Therefore, the utility model realizes the horizontal relative or horizontal misalignment of the unlocking channel 43 with the corresponding limit block 13 and the guide channel 62 through the vertical reciprocating motion of the locking plate 4, thereby realizing the unlocking or locking of the connection part 11 by the locking plate 4, and then realizing the unlocking or locking of one end of the filter element 1.

[0050] In addition to the locking structures at one end and the side of the filter element 1, the other end of the filter element 1 is also provided with a locking structure. Figure 1-5 A handle 14 is rotatably mounted on the other end of the filter element 1. In the assembled state, the handle 14 is rotated toward the body 2 to a vertical state and is connected to the body 2 through a snap-fit ​​structure.

[0051] Specifically, the handle 14 is rotatably mounted on the end cover 17, and the handle 14 is an arc-shaped structure, which is convenient for users to grasp. The radial outer periphery of the end cover 17 is relatively provided with two convex connecting shafts 171, and the two ends of the handle 14 are provided with through holes 141 adapted to the connecting shafts 171. The positions of the through holes 141 correspond to the positions of the connecting shafts 171 one by one. The through holes 141 are rotatably sleeved outside the corresponding connecting shafts 171 so that the handle 14 is rotatably mounted on the end cover 17, and the handle 14 is located outside the installation cavity 21. Before installation, the user rotates the handle 14 to a horizontal state or an inclined state to lift the filter element 1 by the handle 14 and install it in the installation cavity 21. After installing the filter element 1, the user releases the handle 14, and the handle 14 automatically rotates to a vertical state due to gravity and is locked with the body 2. The handle 14 is located outside the installation cavity 21 to facilitate users to lift the handle 14 in a vertical state.

[0052] Regarding the clamping structure between the handle 14 and the body 2, the handle 14 is provided with a clamping block 142, and the body 2 is provided with a blocking member 23 corresponding to the clamping block 142. The blocking member 23 is arranged on the outer peripheral side of the other end of the installation cavity 41. In the locked state, the clamping block 142 is clamped under the blocking member 23 to prevent the clamping block 142 from moving upward through the blocking member 23, thereby preventing the other end of the filter element 1 from being lifted upward, and then locking the other end of the filter element 1.

[0053] The other end of the filter element 1 is provided with a receiving groove 15 adapted to the handle 14, and the receiving groove 15 is provided at the lower edge of the other end of the filter element 1. Therefore, when the handle 14 is rotated to a vertical state, it is stored in the receiving groove 15 and will not swing back and forth, thereby improving the locking stability of the handle 14. In addition, the setting of the receiving groove 15 limits the rotation angle of the handle 14, so that the handle 14 can only rotate within a range of 90° horizontally and vertically downward, and will not rotate upward, so as not to affect the smoothness of the handle 14 automatically rotating to a vertical state.

[0054] Therefore, the principle of the filter element locking assembly of the utility model is:

[0055] In the unassembled state, the locking plate 4 is in a locked state with the unlocking channel 43 and the guide channel 62 being horizontally offset due to the natural extension of the elastic member 5 .

[0056] When installing the filter element 1, the user pulls the locking plate 4 upward and compresses the elastic member 5 so that the unlocking channel 43 and the guide channel 62 are arranged horizontally relative to each other to reach the unlocking state. The user lifts the filter element 1 through the handle 14 and places it horizontally in the installation cavity 21, so that the connecting portion 11 is inserted into the receiving groove 31, and the buckle 12 is clamped in the clamping hole 22. The user releases the handle 14 and the locking plate 4, and the elastic force of the elastic member 5 to restore the deformation pushes the locking plate 4 to move downward until the unlocking channel 43 and the guide channel 62 are arranged horizontally offset, thereby locking the connecting portion 11. The handle 14 automatically rotates to a vertical state due to gravity and is stored in the storage groove 15, and the blocking member 23 blocks the top of the block 142 to prevent the filter element 1 from being lifted upward. In this way, the two ends and the bottom side of the filter element 1 are locked.

[0057] When removing the filter element 1, the user pulls the locking plate 4 upward and compresses the elastic member 5 so that the unlocking channel 43 and the guide channel 62 are arranged horizontally opposite to each other to achieve an unlocking state. The user rotates the handle 14 and slightly lifts the filter element 1 upward through the handle 14 to disengage the buckle 12 from the clamping hole 22, and then pulls the handle 14 horizontally to disengage the connecting portion 11 from the locking structure, thereby realizing the removal of the filter element 1.

[0058] In addition to the above filter element locking assembly, the utility model also provides a water purifier, which includes a sealing plate 7 and the above filter element locking assembly, and the sealing plate 2 is installed at the opening of the body 4. When the filter element 1 needs to be installed or removed, the sealing plate 7 is removed from the body 2, and the filter element 1 can be operated.

[0059] The filter element 1 in the water purifier of the present invention is designed with locking structures at both ends and the bottom side, so that the filter element 1 can be installed horizontally and stably in the water purifier, ensuring the smooth use of the water purifier.

[0060] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
