[0042] Water purifiers are widely used in daily life and other fields. However, the water inlet and outlet of the water purifier are currently connected to the water equipment through hoses, which makes the internal pipes of the water purifier complicated, making it very inconvenient during installation and maintenance, and seriously affecting the production and maintenance efficiency of the water purifier.

[0043] Water purifiers are widely used in daily life and other fields. In the process of purifying water, the water purifier needs to clean the filter element. After cleaning the filter element, the water purifier will produce a large amount of wastewater. These wastewaters are often discharged directly to the outside of the water purifier and discharged as polluted water, which causes the water purifier to waste more water resources.

[0044] In view of this, this embodiment provides a water purifier 100. The water purifier 100 can reduce the waste of water resources.

[0045] See also Figure 1 , a water purifier 100, comprising:

[0046] The filter element 10 has a filter element water inlet 11, a filter element water outlet 12, and a filter element wastewater outlet 13;

[0047] The valve body 20 includes a first water inlet 21, a second water inlet 22, a first water outlet 23, and a second water outlet 24; the first water inlet 21 is connected to the first water outlet 23; the second water inlet 22 is connected to the second water outlet 24; the first water inlet 21 is connected to the filter element water outlet 12, and the second water inlet 22 is connected to the filter element water inlet;

[0048] The valve body 20 in the above-mentioned water purifier 100 includes a first water inlet 21 and a first water outlet 23. The first water inlet 21 is connected to the filter element water inlet 11, and the first water outlet 23 is connected to the water-using equipment to transport the pure water generated by the water purifier 100 to the water-using equipment for use. The valve body 20 also includes: a second water inlet 22 and a second water outlet 24. The second water outlet 24 is connected to the municipal pipeline. In this way, the water flows into the valve body 20 through the second water outlet 24 and is discharged through the second water inlet 22. During installation, the first water inlet 21 is directly connected to the filter element water inlet 11, and the second water inlet 22 and the filter element water outlet 12 are connected through a customized pipe. This can reduce the length of the pipes required to be connected in the water purifier and the number of pipes, which is convenient for connecting and maintaining the water channels in the water purifier.

[0049] As can be understood, the filter element 10 has a filter element water inlet 11, a filter element water outlet 12, and a filter element wastewater outlet 13, wherein the filter element water inlet 11 is connected to the booster pump 50, which is used to provide pressurized municipal water to the filter element 10; the filter element 10 also includes a filter element water outlet 12 and a filter element wastewater outlet 13, wherein the filter element water outlet 12 is used to discharge pure water, and the filter element water outlet 12 is connected to the first water inlet 21 to provide pure water to the valve body 20 and the connecting valve 30. The filter element wastewater outlet 13 is used to discharge wastewater from the filter element 10. In this embodiment, the second water inlet 22 is connected to the booster pump 50, which inputs the pressurized municipal water into the filter element 10 after the booster pump 50 has increased the pressure.

[0050] See also Figure 1 and Figure 2 , in some embodiments, further comprising a connecting valve 30 and a heating tank 40;

[0051] The connecting valve 30 includes a connecting valve water inlet 31, a first connecting valve water outlet 32, and a second connecting valve water outlet 33; the connecting valve water inlet 31 is connected to the first connecting valve water outlet 32 ​​and the second connecting valve water outlet 33 respectively;

[0052] The heating tank 40 has a heating tank water inlet 41 , and the heating tank water inlet 41 is connected to the first connecting valve water outlet 32 ​​.

[0053] It can be understood that the water inlet 31 of the first connecting valve is connected to the first water outlet 23. When the water flows into the first connecting valve 30, the first connecting valve 30 divides the water flow into two paths, one of which is discharged through the first connecting valve water outlet 32, and the other is discharged through the second connecting valve water outlet 33. The water equipment can use multiple channels to utilize the water flow in the water purifier 100 to achieve multiple functions.

[0054] It can be understood that the valve body 20 and the connecting valve 30 are connected together so that the connecting valve 30 and the valve body 20 form a whole. The above-mentioned valve body 20 can connect the water channels on each device through a hose, which can effectively optimize the internal space occupancy of the water purification equipment and make the water purification equipment more convenient during maintenance, so as to reduce the maintenance cost of the water purifier 100 and improve the maintenance efficiency of the water purifier 100.

[0055] It can be understood that the heating tank 40 has a heating tank water inlet 41, which is arranged at the top of the heating tank 40. The heating tank water inlet 41 is connected to the first connecting valve water outlet 32, so that pure water can be input into the heating tank 40; when the water flows into the heating tank 40, the heating tank 40 starts to heat the pure water in the heating tank 40, and heats the water to a preset temperature (the preset temperature can be 40°~90°, and the user can set it according to actual conditions). When the user needs to use hot water, it can be transported to the water-using equipment through the water outlet waterway of the heating tank 40.

[0056] Optionally, the valve body 20 and the connecting valve 30 may both be solenoid valves or other valves.

[0057] See also Figure 8 , in some embodiments, the water purifier 100 further includes: a booster pump 50;

[0058] The booster pump 50 includes a booster pump water inlet 51 and a booster pump water outlet 52 ; the booster pump water inlet 51 is connected to the municipal water pipe, and the booster pump water outlet 52 is connected to the filter element water inlet 11 .

[0059] It can be understood that the booster pump 50 is used to increase the pressure of the water flow that has not entered the filter element 10, so that the water flow can evolve through the filter element 10 and flow out of the filter element 10; this is because the filter element 10 is provided with an RO (Reverse Osmosis) membrane. Generally, the water pressure of the water flow itself may not be sufficient to allow the water flow to pass through the RO filter element. In order to allow the water flow to pass through the RO filter element smoothly, the booster pump 50 is provided to increase the pressure of the water flow so that the water flow can flow through the RO filter element to ensure the purification efficiency of the filter element 10.

[0060] It can be understood that the booster pump 50 includes a booster pump water inlet 51 and a booster pump water outlet 52, wherein the booster pump water inlet 51 is connected to the second water inlet 22, and the booster pump water outlet 52 is connected to the filter element water inlet 11. After being pressurized by the booster pump 50, domestic water is discharged through the booster pump water outlet 52 and flows into the filter element 10.

[0061] See also Figure 3 、 Figure 6 , in some embodiments, further comprising a pipe assembly 60;

[0062] The drainage pipe assembly 60 includes a fixing member 61, a drainage pipe 62, a connecting plate 90, and a water outlet waterway;

[0063] The fixing member 61 is fixedly arranged on the connecting plate 90 , and a plurality of slots 63 are provided along the length direction of the fixing member 61 . The drain pipe 62 is arranged in the slot 63 , and the drain pipe 62 is respectively connected to the water outlet channel and the first connecting valve outlet 32 ​​.

[0064] As can be understood, the fixing member 61 is fixedly mounted in the housing 70. A plurality of slots 63 are provided on the fixing member 61. The slots 63 are arranged along the length of the fixing member 61. The number of slots 63 can be set according to the number of connectors. The slots 63 are used to limit the movement of the drain pipe 62 so that the pipe can be smoothly connected to the connector, thereby improving the installation efficiency of the water purifier 100. The drain pipe 62 has a first connection port and a second connection port relative to each other; the first connection port is used to connect to the pipeline inside the water purifier 100; the second connection port is used to connect to the municipal water pipe.

[0065] See also Figure 5 , in some embodiments, further comprising: a housing 70;

[0066] The housing 70 includes a first baffle 71, a second baffle 72, and a third baffle 73;

[0067] The first baffle 71 and the second baffle 72 are spaced apart in a first direction within the housing 70 , and the third baffle 73 is disposed in a direction perpendicular to the first baffle 71 and / or the second baffle 72 within the housing 70 .

[0068] It can be understood that the shell 70 is provided with a first baffle 71, a second baffle 72 and a third baffle 73, wherein the third baffle 73 is arranged in the shell 70 along the second direction (the thickness direction of the third baffle 73), and the third baffle 73 divides the shell 70 into two parts, upper and lower; wherein the first baffle 71 and the second baffle 72 are arranged at intervals in the upper part of the shell 70 along the first direction (that is, the length direction of the shell 70), and the first baffle 71 and the second baffle 72 divide the upper part into three accommodating chambers; that is, the lower part of the shell 70 is one accommodating chamber, and the upper part of the shell 70 includes three accommodating chambers.

[0069] See also Figure 5 In some embodiments, the first baffle 71 and the side wall of the housing 70 enclose a first accommodating cavity 74, and the second baffle 72 and the side wall of the housing 70 enclose a second accommodating cavity 75; a mounting cavity 76 is provided on a side of the housing 70 away from the second accommodating cavity 75;

[0070] The filter element 10 is disposed in the installation cavity 76 , the booster pump 50 is disposed in the first accommodating cavity 74 , and the heating tank 40 is disposed in the second accommodating cavity 75 .

[0071] It can be understood that the above-mentioned shell 70 is divided into an installation chamber 76 (for installing the filter element 10), a first accommodating chamber 74 (for installing the boost pump 50), and a second accommodating chamber 75 (for installing the heating tank 40). The above-mentioned installation chamber 76, the first accommodating chamber 74, and the second accommodating chamber 75 are arranged in sequence along the first direction. This arrangement can separate the hot tank and the filter element 10. This is because the heating tank 40 will generate a large amount of heat when heating the filtered water, and the active substance in the filter element 10 will change its properties under high temperature environment, which will affect the service life of the filter element 10. After isolating the heating tank 40 and the filter element 10, the influence of the high temperature generated by the heating tank 40 on the filter element 10 can be greatly reduced, so as to ensure the service life and normal use of the filter element 10.

[0072] The mounting cavity 76 is semi-enclosed, with both the top and the side of the mounting cavity 76 away from the heating tank 40 being open, which facilitates installation and removal of the filter element 10. The mounting cavity 76 being located on the side away from the heating tank 40 also isolates the heat generated by the heating tank 40, preventing the heat from affecting the filter element 10 and deteriorating the filter material therein, thereby affecting the normal use of the filter element 10.

[0073] See also Figure 4 and Figure 7 , in some embodiments, further comprising: a connecting plate 90;

[0074] The connecting plate 90 is disposed in the housing 70 , and the valve body 20 and the connecting valve 30 are both disposed on the connecting plate 90 .

[0075] It can be understood that the connecting plate 90 is used to carry the valve body 20, the connecting valve 30, and the drain pipe assembly 60. The valve body 20, the connecting valve 30, and the drain pipe assembly 60 are all detachably arranged on the connecting plate 90, and the valve body 20 and the connecting valve 30 are connected, that is, the water flow from the valve body 20 can flow into the connecting valve 30. By arranging the valve body 20, the connecting valve 30, and the drain pipe assembly 60 on the connecting plate 90, the valve body 20, the connecting valve 30, and the drain pipe assembly 60 form a whole. During the manufacturing process of the water purifier 100, the valve body 20, the connecting valve 30, and the drain pipe assembly 60 can be directly installed on the connecting plate 90, thereby improving the installation efficiency of the water purifier 100.

[0076] See also Figure 4 , in some embodiments, further comprising: a flow sensor 80;

[0077] The flow sensor 80 is disposed on the connecting plate 90 , and the flow sensor 80 is disposed at the connection between the valve body 20 and the connecting valve 30 .

[0078] It can be understood that the flow sensor 80 is used to detect the flow rate flowing from the first water outlet 23 into the first connecting valve 30. The flow rate entering the first connecting valve 30 is the flow rate of the purified water of the filter element 10; therefore, the service life of the filter element 10 can be judged according to the flow sensor 80. When the filter element 10 purifies a preset amount of water flow, the user can be reminded to replace the filter element 10. At the same time, the flow meter can also detect the current amount of purified water of the filter element 10.

[0079] See also Figure 7 In some embodiments, the connecting plate 90 includes a connecting portion 91, a first limiting portion 92, and a second limiting portion 93;

[0080] The first limiting portion 92 and the second limiting portion 93 are spaced apart on both sides of the connecting portion 91 and correspond to the position of the flow sensor 80 . The first limiting portion 92 and the second limiting portion 93 are both perpendicular to the connecting portion 91 .

[0081] It can be understood that the limiting member includes a first limiting portion 92 and a second limiting portion 93, wherein the first limiting portion 92 is arranged on one side, and the second limiting portion 93 is arranged on a side opposite to the first limiting portion 92, and the connecting portion 91 is used to connect the first limiting portion 92 and the second limiting portion 93, and the first limiting portion 92 and the second limiting portion 93 are vertically arranged on the connecting portion 91;

[0082] Among them, the connecting part 91 is used to support the valve body 20, the connecting valve 30 and the drain pipe assembly 60, and the first limiting part 92 and the second limiting part 93 are located at the connection between the valve body 20 and the connecting valve 30, and are used to protect the flow sensor 80; this is because the connection between the valve body 20 and the connecting valve 30 is relatively fragile. In order to improve the stability of the connection between the valve body 20 and the connecting valve 30, the first limiting part 92 and the second limiting part 93 are set to improve the structural strength of the connecting plate 90, thereby improving the stability of the entire water purifier 100.

[0083] See also Figure 2 In some embodiments, the water purifier 100 further includes: a one-way valve 43 ; an exhaust port 42 is provided on the top of the heating tank 40 , and the exhaust port 42 is provided with a one-way valve 43 .

[0084] It can be understood that the top of the heating tank 40 is provided with an exhaust port 42. When the water in the heating tank 40 is heated, water vapor is generated in the heating tank 40, which increases the water vapor in the heating tank 40 and thus increases the air pressure in the heating tank 40. The exhaust port 42 is provided at the top of the heating tank 40 so that the water vapor can be smoothly discharged to the outside of the heating tank 40 without affecting the storage of hot water in the heating tank 40. A one-way valve 43 is provided at the exhaust port 42. The one-way valve 43 can be a safety valve or a one-way safety valve. When the pressure in the heating tank 40 is greater than a preset value, the valve core of the one-way valve 43 is pushed up by the air pressure, that is, the one-way valve 43 is opened, so that the water vapor in the heating tank 40 can be discharged.

[0085] It should be noted that the water flow direction in this application is that the municipal pipeline is connected to the drain pipe 62, the water flows into the water purifier through the drain pipe 62, then enters the second water outlet 24, and is discharged from the second water inlet 22, and then enters the booster pump 50 for pressurization, and after pressurization, enters the valve body 20 through the first water inlet 21 and flows out of the valve body through the first water outlet 23, and enters the connecting valve 30. The connecting valve 30 divides the pure water into two paths, one path flows out from the first connecting valve outlet 32 ​​and flows into the heating tank 40, and the other path flows out from the second connecting valve outlet 33 for direct use by users.
