[0066] Combine the following Figure 1-Figure 14 Describe the water purifier of the utility model. It can be understood that the water purifier is a water purification device, which is a water treatment equipment that deeply filters and purifies the water according to the requirements for water use. The water purifier can effectively filter out rust, sand, colloids in the water, and adsorb residual chlorine, odor, discoloration, pesticides and other chemical agents in the water. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in the water. It is widely used in both civil and commercial use. The under-kitchen water purifier is a water purifier installed at the water supply terminal in the kitchen, which can bring clean water to every family, and the installation is very simple, convenient, reasonable and does not take up space. When using it, just turn on the faucet to get clean water, which is quick and convenient.

[0067] See also Figure 1 As shown, the water purifier according to the embodiment of the utility model includes a housing 100 , a waterway plate 300 , a filter element 200 , a booster pump 410 and a control board 420 .

[0068] Specifically, the housing 100 can provide an installation position and a space for accommodating the filter element 200, the waterway plate 300, the booster pump 410 and the control board 420. Fig. 9 As shown, the housing 100 is provided with a filter element support 120, a first mounting seat 130, a second mounting seat 140 and a third mounting seat 150. The housing 100 is provided with an installation space, and the filter element support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 are all located in the installation space.

[0069] The waterway plate 300 is disposed in the first mounting seat 130 and connected to the first mounting seat 130, and the filter element 200 is disposed in the filter element support 120, and the filter element 200 is used to filter water. Fig.10As shown, the filter element support 120 has a cylindrical storage cavity, one end of which is open to form a first opening 121. The filter element 200 is suitable for installation or removal from the first opening 121. The first opening 121 is provided on the peripheral wall of the housing 100. The filter element 200 can be installed from the direction facing the peripheral wall of the housing 100, which is convenient for users to replace it later. The filter element 200 is movable along the axial direction of the storage cavity so that the filter element 200 is plugged and connected with the waterway plate 300. That is to say, during the installation process, the filter element 200 as a whole moves linearly along the axial direction of the storage cavity, and does not need to rotate as a whole, thereby simplifying the connection structure between the filter element 200 and the waterway plate 300 and avoiding the complication of the structure of the waterway plate 300. The waterway plate 300 may include a plurality of pipes and valves. The waterway plate 300 may be connected to a water source to supply water to the water purifier; at the same time, the waterway plate 300 may also discharge the sewage generated in the filter element 200. The waterway plate 300 is connected and communicated with the filter element 200 , and water enters the filter element 200 through the waterway plate 300 to be filtered and then provided to the user.

[0070] The booster pump 410 is connected to the waterway plate 300, and is used to increase the pressure of the water in the waterway plate 300 so that the water can flow smoothly between the waterway plate 300 and the filter element 200. The booster pump 410 is disposed in the second mounting seat 140 and connected to the second mounting seat 140. The control board 420 is disposed in the third mounting seat 150 and connected to the third mounting seat 150. The control board 420 can be connected to the booster pump 410 or the valve on the waterway plate 300 to control the working state of the booster pump 410 or control the opening of the valve.

[0071] See also Fig.10 As shown, according to some embodiments of the utility model, the housing 100 further includes a panel 110, and an installation space is constructed in the panel 110, and the filter element support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 are all located in the panel 110, wherein one end of the filter element support 120 is connected to the panel 110, and the first opening 121 is located on the panel 110. At least two of the panel 110, the filter element support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 are formed into an integrated part through an integrated molding process. Thereby reducing the number of parts that need to be assembled on the housing 100, reducing the production steps and the required production machines, so as to reduce costs. At the same time, the assembly steps of the housing 100 are simplified, and the production efficiency is improved. In addition, during the assembly process, it is not necessary to turn over the panel 110 multiple times to install it, which simplifies the installation steps.

[0072] For example, the enclosure 110 and the filter cartridge support 120 can be integrally formed by injection molding, that is, the enclosure 110 and the filter cartridge support 120 are molded simultaneously by a one-time injection molding process to construct an integrated component; or, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 can be integrally formed by injection molding, that is, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 are molded simultaneously by a one-time injection molding process to construct an integrated component; or, the enclosure 110, the filter cartridge support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 are integrally formed by injection molding, and the enclosure 110, the filter cartridge support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 form an integrated component. In this way, the assembly process of the enclosure 110, the filter element support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 can be omitted, thereby greatly reducing production costs, simplifying assembly steps, reducing production costs and improving production efficiency.

[0073] The storage space defined by the first mounting seat 130 is provided with an opening, through which the waterway plate 300 is installed or removed. For the convenience of description, the side wall of the first mounting seat 130 opposite to the opening is the bottom wall of the first mounting seat 130. The storage space defined by the second mounting seat 140 is provided with an opening, through which the booster pump 410 is installed or removed. The wall surface of the second mounting seat 140 opposite to the opening is the bottom wall of the second mounting seat 140. The storage space defined by the third mounting seat 150 is provided with an opening, through which the booster pump 410 is installed or removed. The wall surface of the third mounting seat 150 opposite to the opening is the bottom wall of the third mounting seat 150.

[0074] The opening of the storage space defined by the first mounting seat 130, the opening of the storage space defined by the second mounting seat 140, and the opening of the storage space defined by the third mounting seat 150 are all facing one side of the installation space, so that the waterway plate 300, the booster pump 410, and the control board 420 can all be assembled from one side of the installation space, avoiding multiple flipping of the housing 100 during the assembly process, thereby simplifying the assembly process. It is understandable that in the process of flipping the housing 100, due to factors such as the flipping speed and the limitation of the working space, the assembled parts or lines are prone to loosening and falling off, or collision damage. By setting the opening of the storage space defined by the first mounting seat 130, the opening of the storage space defined by the second mounting seat 140, and the opening of the storage space defined by the third mounting seat 150 to face one side of the installation space, the probability of damage to parts such as the waterway plate 300, the booster pump 410, and the control board 420 during the assembly process is reduced, and the yield rate is improved.

[0075] In some embodiments, one side of the installation space is open, and the opening of the storage space defined by the first mounting seat 130, the opening of the storage space defined by the second mounting seat 140, and the opening of the storage space defined by the third mounting seat 150 are all facing the open side of the installation space to allow the water circuit plate 300, the boosting pump 410, and the control panel 420 to be installed or disassembled.

[0076] like Figure 3 As shown, the shell 100 constructs a rectangular installation space, wherein the installation space has two opposite and largest first side surfaces and a second side surface, at least one of the first side surface and the second side surface is open, and the opening of the storage space defined by the first mounting seat 130, the opening of the storage space defined by the second mounting seat 140, and the opening of the storage space defined by the third mounting seat 150 can all face the open first side surface or the second side surface, which facilitates the installation or disassembly of the waterway plate 300, the booster pump 410 and the control panel 420.

[0077] For example, when the first side is open, the opening of the storage space defined by the first mounting seat 130, the opening of the storage space defined by the second mounting seat 140, and the opening of the storage space defined by the third mounting seat 150 are all facing the first side. In this way, during the assembly of the water purifier, the water circuit plate 300, the booster pump 410 and the control board 420 can all be assembled from the first side, which is convenient for adjusting the connection structure between the water circuit plate 300, the booster pump 410 and the control board 420, and reduces the frequency of flipping the shell 100, improves the assembly efficiency, and at the same time can reduce the probability of damage to the assembled parts during the assembly process, thereby improving the yield rate.

[0078] According to the water purifier of the embodiment of the utility model, the filter element 200 is arranged to move along the axial direction of the storage chamber so that the filter element 200 is plugged and connected with the waterway plate 300, which simplifies the movement of the filter element 200 during the installation process, thereby simplifying the connection structure between the filter element 200 and the waterway plate 300 and avoiding the complication of the structure of the waterway plate 300. In addition, at least two of the enclosure 110, the filter element support 120, the first mounting seat 130, the second mounting seat 140 and the third mounting seat 150 are formed into an integrated part through an integrated molding process. Thereby reducing the number of parts that need to be assembled on the housing 100, reducing the production steps and the required production machines, so as to reduce costs. At the same time, the assembly steps of the housing 100 are simplified and the production efficiency is improved. In addition, during the assembly process, it is not necessary to flip the enclosure 110 multiple times to install it, which simplifies the installation steps.

[0079] See also Figure 4 and Figure 5According to some embodiments of the present invention, the filter element 200 includes a main body 210 and a cover 220, the main body 210 is suitable for plugging with the waterway plate 300, and the main body 210 and the cover 220 are rotatably connected. One end of the main body 210 is connected to the cover 220, and the other end of the main body 210 may be provided with a connecting pipe, the connecting pipe is suitable for plugging and communicating with the waterway plate 300, a groove is provided on the outer circumferential surface of the connecting pipe, and a sealing ring is embedded in the groove to seal the connection between the connecting pipe and the waterway plate 300. There are multiple connecting pipes, one of which is connected to the water inlet of the filter element 200, and the waterway plate 300 transports water into the filter element 200 through the connecting pipe, and one of the connecting pipes is connected to the water outlet of the filter element 200 to transport the filtered water in the filter element 200 to the waterway plate 300. It can be understood that the connection parts of the main body 210 and the waterway plate 300 are one-to-one corresponding.

[0080] When installing the filter element 200, the cover 220 rotates relative to the main body 210 to drive the filter element 200 to move along the inner wall of the filter element support 120 as a whole, so that the main body 210 moves to the position where it is plugged into the waterway plate 300. In this way, during the process of installing or removing the filter element 200, the main body 210 moves linearly without rotating, so that the connection part on the filter element 200 is smoothly connected to the connection part on the waterway plate 300, so that the user can easily replace the filter element 200, and the waterway plate 300 does not need to be provided with a corresponding rotating mechanism, so as to avoid the complication of the structure of the waterway plate 300.

[0081] See also Figure 5 As shown, in some embodiments, the filter element 200 is cylindrical, and the filter element 200 also includes a connector 225. A center column 214 is provided on the end surface of one end where the main body 210 and the cover body 220 are connected. The axis of the center column 214 is colinear with the axis of the main body 210. The cover body 220 is provided with a center hole. The connector 225 is passed through the center hole and connected to the center column 214 to connect the cover body 220 and the main body 210. The connector 225 and the center column 214 can be threaded or interference fit, and the connector 225 can rotate relative to the center hole. Figure 7 As shown, a positioning rib 226 may be provided on the side of the cover 220 located at the center hole facing the main body 210 . The positioning rib 226 surrounds the center hole and is used to position the center column 214 .

[0082] In some embodiments, a handle 223 is provided on the side of the cover 220 facing away from the main body 210, and the filter element 200 is operated to be installed or removed by the handle 223. A cavity is formed in the handle 223, and a central hole is provided on the bottom wall of the cavity, and one side of the cavity is open for installation of a connector 225. The filter element 200 further includes an end plate 224, which is covered on the cavity, and the end plate 224 is detachably connected to the cover 220, for example, the end plate 224 is buckled with the cover 220.

[0083] See also Figure 3 and Figure 4 As shown, according to some embodiments of the utility model, the outer peripheral wall of the cover body 220 is provided with a guide block 221, and the inner wall of the filter element support 120 is provided with a guide groove 123, and the guide block 221 can slide along the guide groove 123. During the rotation of the cover body 220, the guide block 221 slides along the guide groove 123 to limit the cover body 220. In some embodiments, the guide groove 123 extends spirally along the axial direction of the storage chamber, and the guide block 221 slides along the guide groove 123 to drive the cover body 220 and the main body 210 to move along the axial direction of the storage chamber. One end of the guide groove 123 can be located at the first opening 121, and the other end of the guide groove 123 forms a fixed section with one end parallel to the first opening 121.
