It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0042] In view of this, the present embodiment provides a water purifier 100. The water purifier 100 can extend the service life of the water purifier 100.

[0043] See also Figures 1 to 3 , a water purifier 100, comprising: a housing 10, a fixing member 20, and a connecting member 30;

[0044] The housing 10 has a cavity 11, and a through hole 12 communicating with the cavity 11 is provided on a side wall of one side of the housing 10; the fixing member 20 is fixedly disposed in the cavity 11, and the fixing member 20 is provided with a plurality of slots 21 spaced apart along its length direction;

[0045] The connector 30 is provided in each of the plurality of slots 21 ; the connector 30 is partially located outside the cavity 11 ; a first connecting port 31 and a second connecting port 32 are provided at opposite ends of the connector 30 ;

[0046] The first connection port 31 is located in the cavity 11 , and the second connection port 32 is partially located in the through hole 12 .

[0047] The above-mentioned water purifier 100 includes a shell 10, a cavity 11 is provided inside the shell 10, a fixing part 20 is fixedly provided in the cavity 11, and the fixing part 20 is provided with multiple slots 21 in its length direction, and a connecting part 30 is provided in each of the multiple slots 21. The connecting part 30 is respectively provided with a first connecting port 31 and a second connecting port 32 at the opposite ends, wherein the first connecting port 31 is used to connect the water inlet pipe and the water outlet pipe of the water purifier 100; the connecting part 30 is partially located outside the cavity 11, and the second connecting port 32 is used to connect the pipeline outside the water purifier 100. The provided connecting part 30 can not only improve the installation efficiency of the water purifier 100, but also make the water purifier 100 not easily damaged after multiple installations, thereby improving the service life of the water purifier 100.

[0048] It can be understood that the water purifier 100 includes a shell 10, the shell 10 has a cavity 11, and a fixing part 20 is arranged in the cavity 11. The fixing part 20 is fixed in the cavity 11, and the fixing part 20 is arranged in the shell 10 along the width direction of the shell 10, and a plurality of card slots 21 are provided on the fixing part 20. The card slots 21 are arranged along the length direction of the fixing part 20. The number of card slots 21 can be based on the number of connecting parts 30. The card slots 21 are used to limit the displacement of the connecting part 30 in the cavity 11 so that the pipeline can be smoothly connected to the connecting part 30, thereby improving the installation efficiency of the water purifier 100 during installation.

[0049] It can be understood that the above-mentioned connecting member 30 is arranged in the slot 21, and the first connecting port 31 and the second connecting port 32 are respectively provided at the opposite ends of the connecting member 30, wherein the first connecting port 31 is located in the cavity and is used to connect to the pipeline inside the water purifier 100, and the second connecting port 32 is located outside the cavity 11 and is used to connect to the pipeline outside the water purifier 100. During the production process of the water purifier 100, the pipeline inside the water purifier 100 can be connected to the first connecting port 31. Later, when the user installs the water purifier 100, he only needs to install the relevant pipeline on the second connecting port 32, which can greatly improve the installation efficiency of the water purifier 100.

[0050] For example: the first connection port 31 is used to connect the water inlet pipe inside the water purifier 100 to provide water source for the water purifier 100 and the water outlet pipe to provide pure water to the user; the second connection port 32 is used to connect the municipal pipe outside the water purifier 100 and the connecting pipe of the water equipment.

[0051] See also Figure 3 , in some embodiments, further comprising a clamping member 40;

[0052] A plurality of protrusions 33 are provided at intervals on one side of the connecting member 30 close to the second connecting port 32 . A groove 34 is provided on one side of the connecting member 30 close to the second connecting port 32 . A clamping member 40 is provided in the groove 34 . The clamping member 40 is used to limit the movement of the water pipe.

[0053] It can be understood that a plurality of protrusions 33 are provided on one side of the connecting member 30 close to the second connecting port 32. The protrusions 33 are used to cooperate with the pipeline outside the water purifier 100. The protrusions 33 are inserted into the pipeline and have an interference fit with the pipeline, thereby limiting the movement of the pipeline along its axis and also sealing the pipeline.

[0054] A groove 34 is provided on one side of the connecting member 30 close to the second connecting port 32. The groove 34 is provided on the side walls on opposite sides of the connecting member 30, and the groove 34 is communicated with the interior of the connecting member 30. When the second connecting port 32 is connected to the pipeline, the clamping member 40 is clamped into the groove 34, which can further improve the connection reliability of the pipeline and enable the clamping member 40 to play a better limiting role on the pipeline.

[0055] Optionally, the side of the connector 30 close to the second connection port 32 can be made of an elastic material or a material with a higher hardness. The elastic material is used to accommodate PVC hard pipes, and the material with a higher hardness is used to accommodate some PVC hoses.

[0056] See also Figure 4In some embodiments, the limiting member 50 is detachably connected to the fixing member 20, and a fixing groove 51 adapted to the card slot 21 is provided on the limiting member 50. The fixing groove 51 and the card slot 21 are combined to form a limiting portion 52, and the limiting portion 52 is used to fix the water pipe.

[0057] It can be understood that the limiting member 50 is detachably connected to the fixing member 20, and a fixing groove 51 adapted to the fixing member 20 is provided on the limiting member 50. The fixing groove 51 cooperates with the card slot 21 to form a limiting portion 52. The limiting portion 52 is used to fix the water pipe. Specifically, during installation, the pipe is first fixed to the card slot 21, and then the limiting member 50 is installed on the fixing member 20. Since the fixing groove 51 on the fixing member 20 corresponds to the position of the card slot 21, when the limiting member 50 is installed on the fixing member 20, the fixing groove 51 and the card slot 21 can be enclosed to form the limiting portion 52. The limiting portion 52 can play a better limiting role on the pipe, so as to clamp the pipe and prevent the pipe from moving, thereby achieving fixation and limitation of the pipe.

[0058] See also Figure 5 In some embodiments, the water purifier 100 further includes a heating tank 60 and a drainage assembly 70;

[0059] The heating tank 60 is disposed in the cavity 11 , and a water outlet 61 is provided at the bottom of the heating tank 60 ; the drainage assembly 70 is disposed below the heating tank 60 , and the drainage assembly 70 is connected to the heating tank 60 .

[0060] It can be understood that the water purifier 100 also includes a heating tank 60, which is fixedly arranged in the cavity 11. The heating tank 60 is used to heat the pure water in the water purifier 100 so that the water purifier 100 can discharge both hot pure water and pure water at room temperature. In order to facilitate the discharge of the pure water in the heating tank 60, a water outlet 61 is provided at the bottom of the heating tank 60. The water outlet 61 is used to discharge the hot water in the heating tank 60. A drainage component 70 is connected to the water outlet 61. The drainage component 70 is used to divert the hot water discharged from the heating tank 60 into multiple paths, thereby improving the diversity of water use for users.

[0061] See also Figure 6 In some embodiments, the drainage assembly 70 includes: a water inlet 71, a first drainage outlet 72, and a second drainage outlet 73;

[0062] The water inlet 71 is connected to the water outlet 61 , the first drain outlet 72 is arranged perpendicular to the second drain outlet 73 , and the first drain outlet 72 is arranged parallel to the water inlet 71 .

[0063] It can be understood that the drainage component 70 includes a first drain port 72 and a second drain port 73; wherein the water inlet 71 is connected to the water outlet 61, the first drain port 72 is used to supply water to the water-using equipment, and the second drain port 73 is used to discharge the hot water in the heating tank 60; the first drain port 72 is arranged at a position perpendicular to the second drain port 73, so that the water that has not been discharged in the first drain port 72 can flow back to the second drain port 73, and then be discharged through the second drain port 73, so as to avoid the liquid in the drainage component 70 and the heating tank 60 from being completely discharged, and to avoid residual liquid in the drainage component 70, so that the residual liquid flows back into the heating tank 60 or the liquid in the heating tank 60 is not completely discharged, thereby improving the water discharge efficiency and facilitating the cleaning or maintenance of the heating tank 60.

[0064] In some other embodiments, the first drain port 72 and the second drain port 73 can jointly supply water to the water-using equipment.

[0065] See also Figure 9 , in some embodiments, the drainage assembly 70 further includes a first solenoid valve 74 and a second solenoid valve 76;

[0066] The first solenoid valve 74 is provided at the first drain port 72 , and the first drain port 72 is provided with a first drain pipe 75 , which connects the connecting member 30 and the first drain port 72 ;

[0067] The second solenoid valve 76 is disposed at the second drain port 73 . The second drain port 73 is provided with a second drain pipe 77 . The second drain pipe 77 connects the connector 30 and the second drain port 73 .

[0068] It can be understood that the drainage assembly 70 also includes a first solenoid valve 74 and a second solenoid valve 76, wherein the first solenoid valve 74 is arranged at the first drain port 72, and a first drain pipe 75 is arranged on the first solenoid valve 74, and the first solenoid valve 74 is used to control the opening or closing of the first drain port 72 to allow the water in the heating tank 60 to flow to the water-using equipment, or to close the water flow to the water-using equipment; the second solenoid valve 76 is arranged on the second drain port 73, and a second drain pipe 77 is arranged on the second solenoid valve 76, and the second solenoid valve 76 is used to control the opening and closing of the second drain port 73 to discharge the water in the heating tank 60.

[0069] When the first solenoid valve 74 is open and the second solenoid valve 76 is closed, water can be discharged through the first drain port 72 into the first drain pipe 75 and then output to the water-using equipment through the first drain pipe 75;

[0070] When the first solenoid valve 74 is closed and the second solenoid valve 76 is opened, water can be discharged through the second drain port 73 to discharge the water in the heating tank 60 .

[0071] When the first solenoid valve 74 and the second solenoid valve 76 are both opened, water flows out through the second drain port 73 , and the water remaining in the first drain pipe 75 also flows back into the drain assembly 70 and then flows out through the second drain port 73 .

[0072] See also Figure 7 In some embodiments, the housing 10 includes: a mounting cavity 13, a first accommodating cavity 14, and a second accommodating cavity 15;

[0073] The installation cavity 13, the first accommodating cavity 14, and the second accommodating cavity 15 are arranged in sequence along the length direction of the shell 10, and the heating tank 60 is arranged in the second accommodating cavity 15; the side of the installation cavity 13 away from the second accommodating cavity 15 and the side away from the bottom surface of the shell 10 are both connected to the outside of the shell 10.

[0074] It can be understood that the shell 10 is divided into an installation chamber 13 (for installing the filter element 80), a first accommodating chamber 14 (for installing the boost pump 81), and a second accommodating chamber 15 (for installing the heating tank 60). The installation chamber 13, the first accommodating chamber 14, and the second accommodating chamber 15 are arranged in sequence along the first direction. This is to separate the hot tank and the filter element 80. This is because the heating tank 60 will generate a large amount of heat when heating the filtered water, and the active substance in the filter element 80 will change its properties under high temperature environment, which will affect the service life of the filter element 80. After isolating the heating tank 60 and the filter element 80, the impact of the high temperature generated by the heating tank 60 on the filter element 80 can be greatly reduced, so as to ensure the service life and normal use of the filter element 80.

[0075] As can be understood, the installation cavity 13 is semi-enclosed, with the top and the side away from the heating tank 60 being open, which facilitates the installation or removal of the filter element 80. The installation cavity 13 is located on the side away from the heating tank 60, which can also isolate the heat generated by the heating tank 60, preventing the heat generated by the heating tank 60 from affecting the filter element 80, causing the filter material in the filter element 80 to deteriorate and affecting the normal use of the filter element 80.

[0076] See also Figure 7 and Figure 8 , in some embodiments, the water purifier 100 further includes a filter element 80 and a booster pump 81;

[0077] The filter element 80 is disposed in the installation cavity 13 , the booster pump 81 is disposed in the first accommodating cavity 14 , the booster pump 81 is connected to the filter element 80 , and the filter element 80 is connected to the heating tank 60 .

[0078] It can be understood that the filter element 80 is arranged in the installation cavity 13, the pressure pump is arranged in the first accommodating cavity 14, and the heating tank 60 is arranged in the second accommodating cavity 15; wherein, the booster pump 81 arranged in the first accommodating cavity 14 is used to pressurize the water flow entering the water purifier 100. This is because there is an RO (Reverse Osmosis) membrane in the filter element 80, and it is difficult for the source water to pass through the reverse osmosis membrane by relying on the water pressure of ordinary tap water. Therefore, the water flow is pressurized by the booster pump 81 before flowing into the filter element 80, so that the water flow can flow smoothly through the RO filter element to filter the water flow, and can also improve the purification speed of the filter element 80 to ensure the purification efficiency of the filter element 80.

[0079] It can be understood that the filter element 80 includes a PPC composite filter element and an RO filter element. When filtering water, the water flow is first coarsely filtered through the composite filter element, and then finely filtered through the RO filter element, and then flows out of the filter element 80 through the water outlet 61 and flows into the heating tank 60; the above-mentioned PPC composite filter element is a filter element 80 that combines PP cotton and activated carbon, and the RO filter element is a reverse osmosis pure water machine filter element.

[0080] See also Figure 9 , in some embodiments, further comprising a liquid level sensor 82;

[0081] The liquid level sensor 82 is disposed in the heating tank 60 , and is used to detect the liquid level of the heating tank 60 .

[0082] It can be understood that the liquid level sensor 82 is arranged inside the heating tank 60. The liquid level sensor 82 is mainly used to detect the height of the current liquid level in the heating tank 60. When the liquid level sensor 82 detects the current liquid level of the heating tank 60, it can send relevant control instructions according to the liquid level; when the liquid level reaches the preset height, the water supply pump is controlled to stop working, and when the liquid level is low, the water supply pump is controlled to add liquid to the heating tank 60.

[0083] See also Figure 9 , in some embodiments, the water purifier 100 further includes: a one-way valve 83;

[0084] An exhaust port 84 is provided on the top of the heating tank 60 , and a one-way valve 83 is provided on the exhaust port 84 .

[0085] It is understandable that the top of the heating tank 60 is provided with an exhaust port 84. When the heating tank 60 heats the water flow in the heating tank 60, water vapor is generated in the heating tank 60, which increases the pressure in the heating tank 60. The exhaust port 84 is provided at the top of the heating tank 60 so that the water vapor can be smoothly discharged to the outside of the heating tank 60 without affecting the storage of hot water in the heating tank 60. A one-way valve 83 is provided at the exhaust port 84. The one-way valve 83 can be a safety valve or a one-way safety valve. When the pressure in the heating tank 60 is greater than a preset value, the valve core of the one-way valve 83 is pushed up by the air pressure, that is, the one-way valve 83 is opened, so that the water vapor in the heating tank 60 can be discharged.
