When the water pump 150 is started to supply water, the water purifier 100 stops the first sterilizing lamp 171 when the external air cannot enter the water outlet member 110. When the water pump 150 is stopped, the external air is likely to enter the water outlet member 110 and bacteria are grown, and the first sterilizing lamp 171 is turned on to sterilize the inside of the water outlet member 110. Compared with the prior art, the first disinfection lamp 171 is turned on when the water pump 150 stops, that is, the water purifier 100 does not discharge water, so that bacteria growing in the water outlet member 110 can be avoided, the bacteria are prevented from entering water flow and being taken by a user when the water is used next time, and the health of the user is further protected. The first sterilizing lamp 171 is not turned on when the water pump 150 is started, so that power consumption can be saved, and energy loss can be reduced.

The first sterilizing lamp 171 may be a lamp that emits ultraviolet rays, or may be a lamp that emits a sterilizing substance, and is not limited to the above.

In some embodiments, referring to fig. 2, the water outlet pipe f includes a cold water pipe f1 and a hot water pipe f2, the hot water pipe f2 is provided with a heating device 140, inlets of the cold water pipe f1 and the hot water pipe f2 are both communicated with an outlet of the water pump 150, and outlets of the cold water pipe f1 and the hot water pipe f2 are both communicated with the water outlet 110. At this moment, the cold and hot water pipelines are separately arranged, the water outlet part 110 can be provided with a cold water taking port and a hot water taking port, cold water and hot water are convenient to take, and water using modes of users are various.

With continued reference to fig. 2, the water purifier 100 further includes a first valve element 120. The first valve element 120 has a first inlet 121, a first outlet 122, and a second outlet 123, the first inlet 121 being connected to an outlet of the water pump 150, the first outlet 122 being connected to the cold water line f1, and the second outlet 123 being communicated with the heating device 140. The first valve element 120 controls the first inlet 121 to alternatively conduct with the first outlet 122 and the second outlet 123. At this time, after entering the first valve element 120 through the first inlet 121, the water flows out through the first outlet 122 to directly flow to the cold water pipeline f1 and then flow to the water outlet element 110; or, after flowing out through the second outlet 123, the water is heated by the heating device 140 and then flows to the water outlet member 110, and hot water flows out of the water outlet member 110, so that cold water or hot water can be discharged through one water outlet member 110, and the structure of the water outlet member 110 is simplified.

With reference to fig. 2, the water purifying machine further includes a second valve element 130, the second valve element 130 has a second inlet 131, a third outlet 132 and a water return port 133, the second inlet 131 is connected to the outlet of the heating device 140 and the cold water pipe f, the third outlet 132 is connected to the water outlet element 110, the water return port 133 is connected to the inlet of the water pump 150 through a water return pipe g, wherein the second valve element 130 controls the second inlet 131 to alternatively conduct with the third outlet 132 and the water return port 133.

Therefore, when the water purifier 100 uses cold water, the first inlet 121 and the first outlet 122 are connected, the second outlet 123 is cut off, the second inlet 131 and the third outlet 132 are connected, and the water return port 133 is cut off, and at this time, the water flows through the first inlet 121, the first outlet 122, the cold water pipe f1, the second inlet 131, and the third outlet 132, and then flows out to the water outlet 110. When the water purifier 100 uses hot water, the first outlet 122 is closed, the first inlet 121 and the second outlet 123 are opened, the third outlet 132 is closed, and the second inlet 131 and the return port 133 are opened at an initial stage, so that water flowing out of the purified water tank 181 and residual water such as pipes and valves are circulated through a circulation circuit formed by the first inlet 121, the second outlet 123, the heating device 140, the second inlet 131, the return port 133, the return pipe g, and the water pump 150 and are continuously heated and warmed by the heating device 140. When the water temperature reaches a preset condition, the second inlet 131 and the third outlet 132 are connected, and the water return port 133 is cut off, so that the hot water flowing out of the heating device 140 can flow to the water outlet member 110 for the user to take. In this way, the hot water taken at the water outlet member 110 is completely heated by the heating means 140, rather than being mixed with the cold water and the hot water, which is more helpful to the health of the user. In addition, when taking hot water, ensure that it is hot water all the time from what go out water piece 110 department and flow out, can avoid going out water piece 110 department at first and be the remaining cold water such as pipeline, valve member, could take hot water later, cause user experience to feel not good.

In the above embodiment, the first valve member 120 and the second valve member 130 may be, but not limited to, three-way solenoid valves, which are common components in the art, and the configuration thereof is not particularly limited. The heating device 140 may be a heating wire, a heating rod, etc., and may be a heating component commonly used in the art, and is not limited in this application.

With reference to fig. 2, the water purifying machine further includes a temperature sensing element 160, the temperature sensing element 160 is disposed on the hot water pipe f2 or the heating device 140, and is used for measuring the water temperature of the hot water pipe f2 or the heating device 140, and the second inlet 131 is controlled to be switched and communicated with the third outlet 132 or the water return port 133 along with the water temperature change of the hot water pipe f2 or the heating device 140.

In the embodiment, the temperature sensing element 160 is disposed on the hot water pipe f2 or the heating device 140 to measure the water temperature of the hot water pipe f2 or the heating device 140, and the on state of the second valve element 130 is switched according to the water temperature of the hot water pipe f2 or the heating device 140, so that the control is more precise. The temperature sensing element 160 can be a temperature sensing member commonly used in the art, such as a water temperature meter, and is not described herein in detail. In practical application, the water temperatures of a plurality of gears can be set. When a user selects a target water temperature and the water temperature in the heating device 140 reaches the target water temperature, the temperature sensing element 160 controls the second valve element 130 to switch to the on state.

In some embodiments, referring to fig. 7 to 10, the water pump 150 includes a housing 151, the housing 151 defines a water inlet cavity 1512, a water outlet cavity 1513, and a water passage 1511 communicating the water inlet cavity 1512 and the water outlet cavity 1513, a resilient check structure 152 is disposed in the water passage 1511, the check structure 152 can hermetically space an outlet of the water inlet cavity 1512 from an inlet of the water outlet cavity 1513, and the check structure 152 can conduct the outlet of the water inlet cavity 1512 and the inlet of the water outlet cavity 1513 under the action of water pressure in the water inlet cavity 1512.

In actual use, the drain chamber 1513 is in communication with the first inlet 121, and the inlet chamber 1512 is in communication with the fresh water tank 181. When the water pump 150 is not operating (e.g., when the user is not taking water), the check structure 152 prevents water entering the water chamber 1512 from flowing into the water discharge chamber 1513, thereby greatly reducing the possibility of water accidentally flowing out of the water outlet s of the water outlet member 110.

Specifically, the outlet of the inlet chamber 1512 and the inlet of the drain chamber 1513 are formed on the side wall of the overflow passage 1511. The check structure 152 includes a check member 1521 and an elastic member 1522, and the check member 1521 covers the outlet of the water inlet chamber 1512 and/or the inlet of the water discharge chamber 1513. The check member 1521 seals the outlet of the water inlet cavity 1512 and/or the inlet of the water discharge cavity 1513 under the pressure of the elastic member 1522, and moves away from the outlet of the water inlet cavity 1512 and/or the inlet of the water discharge cavity 1513 against the pressure of the elastic member 1522 under the action of the water pressure in the water inlet cavity 1512, and conducts the water inlet cavity 1512 and the water discharge cavity 1513.

When the water pressure in the water inlet cavity 1512 is smaller than the pressure applied by the elastic member 1522, the check member 1521 blocks the outlet of the water inlet cavity 1512 and/or the inlet of the water discharge cavity 1513, so that the water inlet cavity 1512 and the water discharge cavity 1513 are not communicated. Thus, when the water pump 150 is not activated, the water automatically (e.g., under the pressure generated by its own weight) pushing the check member 1521 to be conducted into the water chamber 1512 and the water discharge chamber 1513, which may cause the water outlet s of the water outlet member 110 to drip water, can be avoided. When the water pump 150 works, water in the water inlet cavity 1512 is pressurized, the water pressure in the water inlet cavity 1512 is greater than the pressure applied by the elastic member 1522, and then the check member 1521 is pushed away to conduct the water cavity and the water discharge cavity 1513, so that smooth water discharge is realized.

The elastic member 1522 may be a spring, a rubber pad, or the like. Understandably, the elastic member 1522 is limited between the check piece 1521 and the inner wall of the flow passage 1511.

Further, the periphery of the check piece 1521 is limited on the housing 151, and the elastic member 1522 is connected between the middle of the check piece 1521 and the housing 151. The middle portion of the check piece 1521 may be elastic or rigid. In other embodiments, the check 1521 can be a rigid plate. The anti-stop piece 1521 is switched between a blocking state and a conducting state when moving integrally under the combined action of the pressure of the elastic piece 1522 and the water pressure of the water inlet cavity 1512. Specifically, the water pump 150 further includes a water inlet nozzle 153 and a water outlet nozzle 154, the water inlet nozzle 153 is communicated with the water inlet cavity 1512 and is connected with the purified water tank 181 through the water outlet pipeline f, and the water outlet nozzle 154 is communicated with the water outlet cavity 1513 and is connected with the first inlet 121.

In some embodiments, referring to fig. 3 to 6, the water discharging member 110 is configured with a water passing cavity 111 and a gas passing cavity 114 separated from the water passing cavity 111, and the top of the water passing cavity 111 is communicated with the gas passing cavity 114. The inlet of the water passing chamber 111 is configured with a water inlet I connected with the cold water pipe f1 and the hot water pipe f2, and the outlet of the water passing chamber 111 is configured with a water outlet nozzle 112. The air passing chamber 114 further has an air passing nozzle 114 to communicate with the outside, and an air outlet q of the air passing chamber 114 communicates with the fresh water tank 181.

When water is used, the water flows into the water outlet member 110 through the water inlet I and flows out through the water outlet nozzle 112 for the user to take. Then, the outside air flows into clean water tank 181 through air chamber 114 and exhaust port q, and the pressure in clean water tank 181 is maintained in balance, so that clean water tank 181 can smoothly discharge water. Like this, hot steam can not directly be discharged to the external world and influence the user, improves user's use and experiences, has also guaranteed that the water in the water purification case 181 outflows smoothly. Meanwhile, when hot water is taken, hot steam in the hot water leaves the water flow through the exhaust port q of the air cavity 114 when entering the water passing cavity 111, so that the influence of the hot steam on the water flow stability of the water outlet s can be greatly reduced.

Specifically, the top of the water outlet member 110 has a mounting opening, and the first sterilizing lamp 171 is mounted at the mounting opening and at least partially located in the water passing cavity 111 to sterilize the water passing cavity 111. Further, the first disinfection lamp 171 faces the water outlet nozzle 112, so as to ensure the disinfection effect on the water outlet nozzle 112.

Specifically, referring to fig. 5 and 6, the inside of the water outlet member 110 is configured with a partition 110a, and the partition 110a partitions the inside of the water outlet member 110 to form a water passing cavity 111 and an air passing cavity 114. Further, specifically, the water outlet member 110 is covered by the body 110b and the mounting seat 110c to form an inner cavity, and the partition 110a is disposed in the inner cavity and partitions the inner cavity to form the water passing cavity 111 and the air passing cavity 114. The first sterilizing lamp 171 is mounted at a mounting port on the mounting seat 110 c.

With continued reference to fig. 3 and 5, a vertical drainage channel 113 is disposed in the water passing cavity 111, and the drainage channel 113 is communicated with the water outlet nozzle 112. When water is used, water flows out through the water inlet I, the drainage channel 113 in the water passing cavity 111 and the water outlet nozzle 112, and due to the fact that the drainage channel 113 is vertically arranged, water flow can completely flow out of the water passing cavity 111 under the action of gravity and cannot be retained in the water passing cavity 111, and bacteria breeding can be avoided.

"the drainage duct 113 is vertically disposed" includes that the drainage duct 113 extends in the vertical direction, and the drainage duct 113 extends in the direction intersecting with the vertical direction and has a height difference at both ends in the vertical direction (for example, the drainage duct 113 is an oblique flow passage).

Understandably, the water outlet nozzle 112 has a water outlet s of the water outlet member 110.

With continued reference to fig. 3 and 4, the aeration nozzle 115 at least partially surrounds the outlet nozzle 112, and the exhaust port q is located at an upper portion of the aeration chamber 114. At this time, the air outlet q is located at the upper part of the water outlet member 110, so that the flow path of the hot steam in the water outlet cavity 111 into the air passing cavity 114 can be shortened, and the outflow of the hot air flow can be accelerated. In addition, the structure of the water outlet member 110 can be simplified, and the occupied space of the water outlet member 110 can be reduced.

In some embodiments, referring to fig. 1 and 2, a second sterilizing light 172 is provided in the fresh water tank 181. Therefore, the purified water in the purified water tank 181 can be sterilized by the second sterilizing lamp 172, which is beneficial to water safety and user health. Specifically, the second sterilizing lamp 172 may be provided at the bottom of the fresh water tank 181. The second sterilizing lamp 172 may have the same configuration as the first sterilizing lamp 171, and thus, a detailed description thereof will be omitted.

In some embodiments, referring to fig. 1, the water purification assembly includes a water source 182 and a filter assembly 190 connected to the water source 182, the filter assembly 190 having a raw water inlet and a purified water outlet, the purified water outlet being connected to a purified water tank 181, the raw water inlet being connected to the water source 182. At this time, raw water supplied from the water source 182 is filtered by the filter unit 192 to obtain purified water, and is stored in the purified water tank 181. When the user uses the purified water in the purified water tank 181, the health of the user is greatly improved.

The raw water refers to water that is not filtered and purified by the filter unit 192, such as tap water. The water source 182 is raw water tank or kitchen water. The raw water tank 182 is a tank body storing raw water. The kitchen water can be water flowing out of a kitchen faucet or water obtained after being directly connected into a kitchen water pipe.

Referring to fig. 1, the filter assembly 192 includes a first activated carbon filter element 191, a reverse osmosis membrane filter element 192, and a second activated carbon filter element 193, which are connected in series in this order.
