[0033] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] As Figure 1 、 Figure 4 shown, a water purifier includes a body 500, a filter element 100, a limiting component 200, an identifier 300, and an identified component 400. An assembly part 51 is provided on the body 500. Both the filter element 100 and the limiting component 200 are connected to the body 500 and are disposed in the assembly part 51. The identifier 300 is also provided on the body 500 and is electrically connected to the limiting component 200. The identifier 300 can control the limiting component 200 to be in a limiting state or an assembly state. The identified component 400 is provided on the filter element 100 for the identifier 300 to perform identification and matching. The identified component 400 can be a component with unique identification information such as a chip or a bar code.

[0035] During actual use, when the recognizer 300 fails to recognize the recognized part 400, the recognizer 300 controls the limiting component 200 to be in a limiting state through a circuit or a wireless signal. The limiting component 200 in the limiting state will block or cover the part of the assembly part 51 of the body 500 for assembling the filter element 100, so that the filter element 100 cannot be assembled to the assembly part 51. When the recognizer 300 recognizes the recognized part 400, the recognizer 300 controls the limiting component 200 to change to an assembly state. At this time, the limiting component 200 will not block the part of the assembly part 51 for assembling the filter element 100, and the filter element 100 can be successfully assembled to the assembly part 51.

[0036] Through the above design, when the user assembles the filter element 100, the qualified filter element 100 can be assembled to the body 500 only after being recognized by the recognizer 300. Thus, it can effectively prevent the user from assembling the unqualified filter element 100 to the body 500 due to the inability to accurately recognize the qualified filter element 100, ensuring the water purification effect of the water purifier, avoiding the problem of deteriorated water quality caused by the unqualified filter element 100, and also avoiding damage to the body 500 caused by the inappropriate filter element 100 being forcibly assembled to the body 500.

[0037] The technical details of each component will be introduced one by one below.

[0038] In some embodiments, as Figure 2 , Figure 3 , Figure 4 shown, the above-mentioned limiting component 200 includes a lifting mechanism 21 and a limiting member 22. The lifting mechanism 21 is arranged on the body 500, and the limiting member 22 is connected to the lifting end of the lifting mechanism 21. Through the lifting mechanism 21, the limiting member 22 can be lifted to move its position. The assembly part 51 is provided with an assembly opening 511. The filter element 100 is connected to the body 500 and inserted into the assembly opening 511. A flow channel interface 53 corresponding to the pipeline inside the filter element 100 is also arranged inside the assembly opening 511. The water to be filtered flows into the filter element 100 through the flow channel interface 53 inside the assembly opening 511 for purification, and then the purified water flows out through the flow channel interface 53.

[0039] In practical applications, when the limiting component 200 is in the limiting state, the limiting member 22 moves to one end of the lifting component close to the assembly port 511 and covers the assembly port 511, thereby preventing the filter element 100 from being assembled into the assembly port 511. When the limiting component 200 is in the assembly state, the limiting member 22 moves to one end of the lifting component away from the assembly port 511. At this time, the limiting member 22 does not block the assembly port 511, and the filter element 100 can be successfully assembled into the assembly port 511. Through the above design, firstly, it can avoid assembling unqualified filter elements 100, secondly, it can protect the body 500, and thirdly, after the limiting member 22 covers the assembly port 511, it can also prevent external dust and other pollutants from entering the assembly port 511.

[0040] In some embodiments, as Figure 4 shown, the above-mentioned filter element 100 is disposed between the limiting member 22 and the assembly port 511; along the radial direction of the filter element 100, the filter element 100 includes an assembly end 11 and a abutting end 12. The assembly end 11 is used for inserting into the assembly port 511, and the abutting end 12 is used for abutting and fixing with the limiting member 22.

[0041] After the filter element 100 is assembled onto the body 500, the assembly end 11 of the filter element 100 is inserted into the assembly port 511. At this time, the limiting member 22 moves and abuts against the abutting end 12 of the filter element 100 to fix the filter element 100, so that the filter element 100 can be inserted into the assembly port 511 more stably and prevent the filter element 100 from loosening.

[0042] As Figure 3 、 Figure 4 shown, the abutting surface of the above-mentioned limiting member 22 and the abutting end 12 of the filter element 100 is provided with a recess 01, and the abutting surface of the abutting end 12 of the filter element 100 and the limiting member 22 is provided with a protrusion 02. The protrusion 02 and the recess 01 are mutually matched and fitted, which can prevent the abutting end 12 of the filter element 100 and the limiting member 22 from sliding and shifting after the limiting member 22 abuts against the abutting end 12 of the filter element 100, and further ensures the stability of the filter element 100 after being assembled onto the body 500.

[0043] In some embodiments, as Figure 4 shown, the above-mentioned identified member 400 is embedded in the contact surface between the filter element 100 and the limiting member 22. After the filter element 100 is assembled onto the body 500, the limiting member 22 can cover the identified member 400, thereby protecting the identified member 400.

[0044] In some embodiments, as Figure 4 、 Figure 5As shown in the figure, the above-mentioned lifting mechanism 21 includes a track 211, a threaded rod 212, a lifting part 213 and a rotating mechanism. The track 211 is arranged on the machine body 500. The threaded rod 212 is arranged inside the track 211 and is connected to the output end of the rotating mechanism. The rotating mechanism can be specifically a kind of motor and is arranged inside the machine body 500. At the same time, the rotating mechanism is also electrically connected to the identifier 300. The lifting part 213 is threadedly connected to the threaded rod 212 and fits against the inner wall of the track 211. The limiting part 22 is fixedly connected to the lifting part 213. It can be understood that when the rotating mechanism drives the threaded rod 212 to rotate, the lifting part 213 can drive the limiting part 22 to slide along the track 211. When the limiting part 22 follows the lifting part 213 and slides along the track 211 to one end of the track 211 close to the assembly port 511, the limiting component 200 is in a limiting state. When the limiting part 22 follows the lifting part 213 and slides along the track 211 to one end of the track 211 away from the assembly port 511, the limiting component 200 is in an assembly state.

[0045] When the identifier 300 fails to identify the identified part 400, the identifier 300 controls the rotating mechanism to rotate so that the lifting part 213 drives the limiting part 22 to move to the assembly port 511 to cover and block the assembly port 511, thereby avoiding the unqualified filter element 100. When the identifier 300 identifies the identified part 400, the identifier 300 controls the rotating mechanism to rotate so that the lifting part 213 drives the limiting part 22 to move to one end of the track 211 away from the assembly port 511. At this time, the filter element 100 can be smoothly inserted into the assembly port 511. Through the above method, it can help the user to distinguish the filter element 100 and ensure the water purification effect of the water purifier.

[0046] In some embodiments, such as Figure 4 、 Figure 5 As shown in the figure, the above-mentioned track 211 includes a main slideway 2111 and an auxiliary slideway 2112. The main slideway 2111 is communicated with the auxiliary slideway 2112 and arranged in parallel. Correspondingly, a sliding head 2131 is arranged at one end of the lifting part 213 away from the limiting part 22. The sliding head 2131 is slidably arranged inside the auxiliary slideway 2112 and can slide along the auxiliary slideway 2112. The side wall of the sliding head 2131 and the auxiliary slideway 2112 can be abutted along the connection direction of the limiting part 22 and the lifting part 213. Through the above design, after the sliding head 2131 abuts against the auxiliary slideway 2112, the swing of the limiting part 22 can be reduced, so that the limiting part 22 can more stably hold and fix the filter element 100 or cover and protect the assembly port 511.

[0047] In some embodiments, such as Figure 4 、 Figure 5As shown, the above-mentioned identifier 300 includes electronic components and an identification unit 31. The identification unit 31 is electrically connected to the electronic components, and the electronic components are electrically connected to the lifting mechanism 21. The identification unit 31 is used to identify the item to be identified 400. After the identification unit 31 identifies the item to be identified 400, it transmits a signal to the electronic components. The electronic components control the lifting component to move the restricting member 22 from the assembly port 511 to a side away from the assembly port 511 through a circuit or a wireless signal, that is, to change the restricting component 200 from the restricting state to the assembly state. Through the above process, it can help the user to distinguish the filter element 100 and ensure the water purification effect of the water purifier.

[0048] In some embodiments, as Figure 2 , Figure 3 shown, a ring convex 54 is provided on the outer periphery of the open end of the above-mentioned assembly port 511. When the restricting component 200 is in the restricting state, the edge of the side surface of the restricting member 22 opposite to the assembly port 511 abuts and fits tightly against the ring convex 54. Thus, the tightness of the restricting member 22 covering and protecting the assembly port 511 can be improved, so that when the filter element 100 is not assembled at the assembly port 511, external pollutants can be prevented from entering the assembly port 511 through the restricting member 22.

[0049] In some embodiments, as Figure 6 shown, a pipeline cavity 52 is formed on the bottom surface of the above-mentioned body 500. An interface 53 connected to the body 500 is provided inside the pipeline cavity 52. The interface 53 is used to connect an external pipeline to the pipeline inside the body 500. A plurality of bayonet openings 521 are also formed on the side wall of the pipeline cavity 52. The bayonet openings 521 are communicated with the external space. The bayonet openings 521 are used to clamp and fix the external pipeline. The bayonet openings 521 are formed on the side walls of the pipeline cavity 52 in all directions. In this way, it is convenient to connect the external pipeline from all directions at the bottom of the body 500, improving the convenience of connecting the external pipeline.

[0050] Please refer to Figure 7 , the water flow inside the water purifier flows in the direction shown in Figure 7 . The interface 53 includes a water inlet 001, a pure water outlet 002, and a wastewater outlet 003. External water flow enters the body 500 through the water inlet 001, then flows through the body 500 into the filter element 100 for filtration, and the purified water and wastewater generated after filtration are discharged through the pure water outlet 002 and the wastewater outlet 003 respectively.

[0051] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "installed", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0052] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
