[0038] In a water purifier, the connector of the water outlet pipe is an important connecting device of the water purifier. The connection structure of the water outlet pipe connector in the related art is simple, the connection is not reliable enough, and it is easy to loosen or leak after long-term use, affecting the normal use of the water purifier. It is also more troublesome to replace and the installation efficiency is low.

[0039] In view of this, the present embodiment provides a water purifier 100. The water outlet pipe connector 30 of the water purifier 100 can be quickly replaced.

[0040] See also Figures 1 to 3 A water purifier 100, comprising a heating tank 10, includes:

[0041] A clamping member 20 is provided at the bottom of the heating tank 10. The clamping member 20 is provided with a connection port 21. The axis of the connection port 21 is perpendicular to the axis of the heating tank 10. The clamping member 20 is provided with grooves 22 on both sides of the connection port 21. A limit member 40 is provided in the groove 22.

[0042] The connecting member 30 is detachably connected to the connecting port 21 and is provided with a plurality of protrusions 31 along the length direction. When the connecting member 30 is installed to the connecting port 21, the protrusions 31 cooperate with the limiting member 40 to realize the displacement of the connecting member 30.

[0043] The bottom of the heating tube in the above-mentioned water purifier 100 is provided with a snap-fitting part 20, which has a connecting port 21, and in order to facilitate the connection between the connecting port 21 and the connecting part 30, the connecting port 21 is set in a direction perpendicular to the heating tube; the connecting part 30 and the connecting port 21 are detachably connected. When the connecting part 30 and the connecting port 21 are connected, the multiple protrusions 31 provided on the connecting part 30 cooperate with the grooves 22 on both sides of the connecting port 21 to restrict the connecting part 30 in the grooves 22, so that the connecting part 30 cannot move, and the multiple protrusions 31 can also be fully adapted to the connecting port 21 and play the role of sealing the connecting port 21, that is, the convenience of connecting the water outlet pipe on the water purifier 100 is improved, so that the connecting port 21 on the water purifier 100 can be quickly disassembled.

[0044] It can be understood that the clamping member 20 is arranged at the bottom of the heating tank 10, so that the water flow in the heating tank 10 can be completely discharged from the bottom of the heating tank 10. A connecting port 21 is provided on the clamping member 20, and the connecting port 21 is provided on one side of the clamping member 20, and the connecting port 21 is provided perpendicular to the clamping member 20. A groove 22 is provided on the connecting port 21, and the groove 22 is provided at the end of the connecting port 21, and the groove 22 is connected to the interior of the connecting port 21; a limiting member 40 is provided in the groove 22, and the limiting member 40 is provided in the groove 22. The limiting member 40 is used to limit the connecting member 30 installed in the connecting port 21. When the connecting member 30 is installed in the connecting port 21, the limiting member 40 can play a role in limiting the movement of the connecting member 30, so that the connecting member 30 can be more firmly matched with the clamping member 20.

[0045] It can be understood that the above-mentioned connecting member 30 is detachably connected to the connecting port 21. Specifically, a plurality of protrusions 31 are provided in the length direction of the connecting member 30. The protrusions 31 are used to cooperate with the clamping member 20. The protrusions 31 are inserted into the clamping member 20 to limit the water outlet pipe, and one of the protrusions 31 away from the clamping member 20 can cooperate with the limiting member 40. A slot is formed in the middle of the plurality of protrusions 31. The limiting member 40 is inserted into the slot between the protrusions 31, which can limit the movement of the connecting member 30 so that the clamping member 20 cannot be displaced, thereby playing a better limiting role on the connecting member 30.

[0046] See also Figures 1 to 4 In some embodiments, the limiting member 40 includes a first limiting portion 41, a second limiting portion 42 and a connecting portion 43;

[0047] The first limiting portion 41 and the second limiting portion 42 are respectively disposed on both sides of the connecting portion 43 . The first limiting portion 41 and the second limiting portion 42 are respectively disposed in the grooves 22 on both sides of the connecting port 21 .

[0048] It can be understood that the limiting member 40 includes a first limiting portion 41 and a second limiting portion 42, wherein the first limiting portion 41 is arranged on one side, and the second limiting portion 42 is arranged on a side opposite to the first limiting portion 41, and the connecting portion 43 is used to connect the first limiting portion 41 and the second limiting portion 42, connecting the first limiting portion 41 and the second limiting portion 42, and the first limiting portion 41 and the second limiting portion 42 are both elastic, and the first limiting portion 41 and the second limiting portion 42 are respectively inserted into the grooves 22 on both sides of the connecting port 21.

[0049] When the connecting member 30 is inserted into the connecting port 21, the position of the slot between the two protrusions 31 corresponds to the position of the groove 22, and the first limiting portion 41 and the second limiting portion 42 pass through the groove 22 and are inserted into the slot, thereby limiting the connecting member 30 and preventing the connecting member 30 from being rushed out of the connecting port 21 due to excessive water pressure.

[0050] See also Figure 4 In some embodiments, the first limiting portion 41 and the second limiting portion 42 are both bent.

[0051] It can be understood that the first limiting portion 41 and the second limiting portion 42 are bent so that the first limiting portion 41 and the second limiting portion 42 can adapt to the size of the connecting member 30, so that the first limiting portion 41 and the second limiting portion 42 can fit the clamping portion between the protrusions 31 on the connecting member 30 after being connected to the groove 22, so that the first limiting portion 41 and the second limiting portion 42 can play a better limiting role.

[0052] In some embodiments, the first limiting portion 41 and the second limiting portion 42 are both elastic;

[0053] It can be understood that the above-mentioned first limiting portion 41 and second limiting portion 42 are both set to elastic materials, so that the first limiting portion 41 and second limiting portion 42 can clamp the connecting member 30 in the clamping member 20 when cooperating with the card slot, so that the limiting member 40 has self-locking ability to avoid the first limiting portion 41 and second limiting portion 42 falling off after long-term use.

[0054] See also Figure 1 In some embodiments, the inner diameter of the clamping member 20 is larger than the outer diameter of the connecting member 30 .

[0055] It can be understood that the inner diameter of the clip 20 is larger than the outer diameter of the connector 30, which makes it easier for the connector 30 to be installed in the clip 20; the connector 30 and the clip 20 can be matched in a transition fit to ensure that the connector 30 will not leak after being installed in the clip 20.

[0056] See also Figure 1In some embodiments, a baffle is provided at a position of the clamping member 20 corresponding to the groove 22 , and the baffle is used to limit the rotation of the limiting member 40 .

[0057] It can be understood that the baffle partially covers the groove 22, and the baffle is set on the clamping part 20. When the limit member 40 is installed on the clamping part 20, the baffle can limit the limit member 40, thereby preventing the limit member 40 from rotating. At the same time, it can also limit the opening and closing degree of the limit member 40, thereby preventing the limit member 40 from falling off after long-term use.

[0058] See also Figure 5 and Figure 6 , in some embodiments, further comprising a drainage assembly 50;

[0059] The drainage assembly 50 has a water inlet 51, a first drain outlet 52, and a second drain outlet 53. The water inlet 51 is connected to the connecting member 30. The first drain outlet 52 is used to supply water to the water-using equipment. The second drain outlet 53 is used to discharge the water in the heating tank 10. The first drain outlet 52 is perpendicular to the second drain outlet 53.

[0060] It can be understood that the drainage component 50 is used for diversion, and the drainage component 50 includes a first drain port 52 and a second drain port 53; wherein, the water inlet 51 is connected to the water outlet, the first drain port 52 is used to supply water to the water-using equipment, and the second drain port 53 is used to discharge the hot water in the heating tank 10; the position of the first drain port 52 is arranged perpendicular to the second drain port 53, so that the water flow that has not been discharged in the first drain port 52 can flow back to the second drain port 53, and then be discharged through the second drain port 53, so that the liquid in the drainage component 50 and the heating tank 10 can be completely discharged, avoiding residual liquid in the drainage component 50 and the heating tank 10, thereby improving the discharge efficiency of the water flow.

[0061] See also Figure 9 , in some embodiments, the drainage assembly 50 further includes a first solenoid valve 54 and a second solenoid valve 56;

[0062] The first solenoid valve 54 is disposed at the first drain port 52 , and the second solenoid valve 56 is disposed at the second drain port 53 . The first solenoid valve 54 is connected to a first drain pipe 55 , and the second solenoid valve 56 is connected to a second drain pipe 57 .

[0063] It can be understood that the drainage assembly 50 also includes a first solenoid valve 54 and a second solenoid valve 56, wherein the first solenoid valve 54 is arranged at the first drain port 52, and a first drain pipe 55 is arranged on the first solenoid valve 54, and the first solenoid valve 54 is used to control the opening or closing of the first drain port 52 to allow the water in the heating tank 10 to flow to the water-using equipment or to close the water flow to the water-using equipment; the second solenoid valve 56 is arranged on the second drain port 53, and a second drain pipe 57 is arranged on the second solenoid valve 56, and the second solenoid valve 56 is used to control the opening and closing of the second drain port 53 to discharge the water in the heating tank 10.

[0064] The above solenoid valve has the following working states:

[0065] When the first solenoid valve 54 is open and the second solenoid valve 56 is closed, water can be discharged through the first drain port 52 into the first drain pipe 55 and then output to the water-using equipment through the first drain pipe 55;

[0066] When the first solenoid valve 54 is closed and the second solenoid valve 56 is opened, the water can be discharged through the second drain port 53 to discharge the water in the heating tank 10 .

[0067] When the first solenoid valve 54 and the second solenoid valve 56 are both opened, water flows out through the second drain port 53 , and the water remaining in the first drain pipe 55 also flows back into the drain assembly 50 and then flows out through the second drain port 53 .

[0068] See also Figure 8 and Figure 9 , in some embodiments, further comprising a pressurizing pump 60;

[0069] The pressure pump 60 is connected to the connecting member 30 , the pressure pump 60 is connected to the connecting member 30 , and the pressure pump 60 is connected to the connecting member 30 .

[0070] It can be understood that the liquid level sensor 82 is arranged inside the heating tank 10. The liquid level sensor 82 is mainly used to detect the height of the current liquid level in the heating tank 10. When the liquid level sensor 82 detects the current liquid level of the heating tank 10, 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 replenish liquid to the heating tank 10.

[0071] It can be understood that one end of the pressure pump 60 is connected to the water outlet of the heating tank 10, and the other end is connected to the drainage component 50. In actual usage scenarios, the water purifier 100 is mostly placed in a lower position, such as: in a cabinet; in order to enable the water flow in the heating tank 10 to be smoothly transported to the water-using equipment, a pressure pump 60 is set to pressurize the water flow out of the heating tank 10; specifically, the hot water in the heating tank 10 flows out through the water outlet of the heating tank 10 and flows into the pressure pump 60, and then the water flow is pressurized by the pressure pump 60 and transported to the user end for user use. The pressure pump 60 can ensure that the setting position of the heating tank 10 is not affected by the water pressure, and can smoothly transport the hot water in the heating tank 10 to the water-using equipment to enhance the user experience.

[0072] See also Figure 7 and Figure 8 , in some embodiments, the water purifier 100 further includes: a housing 70;

[0073] The housing 70 includes an installation cavity 71 , a first accommodating cavity 72 , and a second accommodating cavity 73 . The installation cavity 71 , the first accommodating cavity 72 , and the second accommodating cavity 73 are sequentially arranged along a first direction.

[0074] It can be understood that the above-mentioned shell 70 is divided into an installation chamber 71 (for installing the filter element 80), a first accommodating chamber 72 (for installing the booster pump 81), and a second accommodating chamber 73 (for installing the heating tank 10). The above-mentioned installation chamber 71, the first accommodating chamber 72, and the second accommodating chamber 73 are arranged in sequence along the first direction. This arrangement can separate the hot tank and the filter element 80. This is because the heating tank 10 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 10 and the filter element 80, the influence of the high temperature generated by the heating tank 10 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] The mounting cavity 71 is semi-enclosed, with both the top and the side of the mounting cavity 71 away from the heating tank 10 being open, which facilitates installation and removal of the filter element 80. The mounting cavity 71 being located away from the heating tank 10 also isolates the heat generated by the heating tank 10, preventing the heat from affecting the filter element 80 and deteriorating the filter material therein, thereby affecting the normal use of the filter element 80.

[0076] See also Figure 8 and Figure 9 , in some embodiments, further comprising: a filter element 80, a booster pump 81;

[0077] The filter element 80 is arranged in the installation cavity 71, the booster pump 81 is arranged in the first accommodating cavity 72, and the heating tank 10 is arranged in the second accommodating cavity 73; the booster pump 81 is connected to the filter element 80, and the filter element 80 is connected to the heating tank 10.

[0078] It can be understood that the filter element 80 is arranged in the installation cavity 71, the pressure pump 60 is arranged in the first accommodating cavity 72, and the heating tank 10 is arranged in the second accommodating cavity 73; wherein, the booster pump 81 arranged in the first accommodating cavity 72 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 80 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 80 and an RO filter element 80. When filtering water, the water flow is first coarsely filtered through the composite filter element 80, and then finely filtered through the RO filter element 80, and then flows out of the filter element 80 through the water outlet and flows into the heating tank 10; the above-mentioned PPC composite filter element 80 is a filter element 80 that combines PP cotton and activated carbon, and the RO filter element 80 is a reverse osmosis pure water machine filter element 80.

[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 10 , and is used to detect the liquid level of the heating tank 10 .

[0082] It can be understood that the liquid level sensor 82 is arranged inside the heating tank 10, and the liquid level sensor 82 is mainly used to detect the height of the current liquid level in the heating tank 10; when the liquid level sensor 82 detects the water level height of the liquid in the current heating tank 10, it can feedback relevant data to the controller 90 to display the current liquid level of the heating tube; or when the liquid level sensor 82 detects the current liquid level height of the heating tank 10, it can feedback relevant data to the controller 90, and the controller 90 outputs relevant instructions based on the input data. Specifically, when the liquid level reaches a preset height, the controller 90 controls the water supply pump to stop working, and when the liquid level is low, the controller 90 controls the water supply pump to add liquid to the heating tank 10.

[0083] The controller 90 can be disposed in the heating tank 10 . The controller 90 can be disposed at any position in the water purifier 100 and connected to the liquid level sensor 82 and the water supply pump to play a control role.

[0084] See also Figure 9 In some embodiments, the water purifier 100 further includes: a one-way valve 84 ; an exhaust port 83 is provided on the top of the heating tank 10 , and the one-way valve 84 is provided at the exhaust port 83 .

[0085] It can be understood that the top of the heating tank 10 is provided with an exhaust port 83. When the water in the heating tank 10 is heated, water vapor is generated in the heating tank 10, which increases the water vapor in the heating tank 10 and increases the air pressure in the heating tank 10. The exhaust port 83 is provided at the top of the heating tank 10 so that the water vapor can be smoothly discharged to the outside of the heating tank 10 without affecting the storage of hot water in the heating tank 10. A one-way valve 84 is provided at the exhaust port 83. The one-way valve 84 can be a safety valve or a one-way safety valve. When the pressure in the heating tank 10 is greater than a preset value, the valve core of the one-way valve 84 is lifted by the air pressure, that is, the one-way valve 84 is opened, so that the water vapor in the heating tank 10 can be discharged.
