As shown in fig. 1 to 14, a drinking apparatus 200 according to an embodiment of the present utility model includes a water tank 210 and a water source switching mechanism 100, wherein the water tank 210 includes a water tank outlet 211.

Specifically, the water source switching mechanism 100 includes a first waterway assembly 110, a first valve 120, a booster pump (not shown), a second valve 140, a water pressure monitoring assembly 150, a second waterway assembly 160, a third valve 180, a first sealing cover 20, and a second sealing cover 30.

Referring to fig. 4 to 7, the first waterway assembly 110 has a tap water inlet 111, a tank water inlet 112, and a water outlet 113. The tap water inlet 111 communicates with the water outlet 113 such that a water flow entering from the tap water inlet 111 can flow out through the water outlet 113. The water tank inlet 112 communicates with the water outlet 113 such that water flow entering from the water tank inlet 112 can also flow out through the water outlet 113. The first sealing cover 20 is detachably provided at the tap water inlet 111. The first sealing cap 20 is installed at the tap water inlet 111 such that the tap water inlet 111 is closed. After the first sealing cap 20 is removed, the tap water inlet 111 is opened so that tap water or the like can flow in through the tap water inlet 111. The first valve 120 is disposed at the tank inlet 112. The first valve 120 is opened and water flowing out of the water tank 210 may flow in through the water tank water inlet 112. The first valve 120 is closed such that the tank inlet 112 is closed.

Thus, the first sealing cover 20 is covered at the tap water inlet 111, and when the first valve 120 is opened, the water tank outlet 211 of the water tank 210 may flow to the water outlet 113 through the water tank inlet 112. When the first sealing cover 20 is lifted from the tap water inlet 111 and the first valve 120 is closed, tap water can flow to the water outlet 113 through the tap water inlet 111.

The water source switching mechanism 100 controls the opening and closing of the tap water inlet 111 and the water tank inlet 112 through the first sealing cover 20 and the first valve 120, respectively, so that the water flow can be selected to enter from the tap water inlet 111 or the water tank inlet 112 according to the needs, and the tap water or the water in the water tank can be selected to be used according to the needs.

Referring to fig. 8a and 8b, the first valve 120 has a first valve water inlet 121. The water source switching mechanism 100 further includes a first adapter 10. One end of the first adapter 10 is abutted with the first valve water inlet 121 of the first valve 120, and the other end is abutted with the water tank water outlet 211 of the water tank 210. It is understood that the water tank outlet 211 is an opening in the water tank 210 for water to flow out.

Of course, the first valve 120 also has a first valve outlet 122. It will be appreciated that the first valve outlet 122 interfaces with the tank inlet 112. Accordingly, the water flow flowing into the first valve 120 can flow into the water source switching mechanism 100 through the water tank water inlet 112. In the embodiment shown in fig. 8, the water flowing into the first valve 120 can flow into the second chamber 115 of the water source switching mechanism 100 through the water tank inlet 112. The arrangement of the second chamber 115 will be described in detail later.

Optionally, the water source switching mechanism 100 further includes a booster pump (not shown), and the booster pump (not shown) is disposed at the water outlet 113. The booster pump can convert low-pressure liquid into high-pressure liquid, namely, through the arrangement of the booster pump (not shown), the flow speed of water flow can be increased, and then proper water pressure and water flow are provided for the subsequent filter element filtration.

Referring to fig. 4-7, 9-11, the water source switching mechanism 100 further includes a second valve 140. The second valve 140 is positioned between the tap water inlet 111 and the water outlet 113, i.e., the water flowing into the tap water inlet 111 flows to the water outlet 113 after passing through the second valve 140. The second valve 140 is opened and the water flowing into the tap water inlet 111 can flow to the water outlet 113. The second valve 140 is closed, and the flow path between the tap water inlet 111 and the water outlet 113 is cut off, so that the water flowing into the tap water inlet 111 cannot flow to the water outlet 113.

Specifically, the water source switching mechanism 100 includes two second valves 140. One of the two second valves 140 is a normally open valve and the other is a normally closed valve. Providing two second valves 140 may better provide dual protection for the flow path between the tap water inlet 111 and the water outlet 113. Even if one of the second valves 140 is damaged, the other second valve 140 can be controlled to be closed so as to avoid water overflow. So that the safety of the water source switching mechanism 100 can be better ensured. Accordingly, when the water source switching mechanism 100 is mounted on the drinking apparatus, the safety of the drinking apparatus can be better ensured.

In addition, if a second valve is provided, when the purified water in the purified water tank is excessively purified and the second valve is damaged, the purified water in the purified water tank is easily returned to the tap water inlet 111. If two second valves 140 are provided, even if one of the second valves 140 is damaged, the other second valve 140 can be controlled to be closed so as to prevent the water in the clean water tank from flowing back to the tap water inlet 111. Therefore, even if the first sealing cap 20 at the tap water inlet 111 is not in the closed state, or the first sealing cap 20 is damaged, the flow of water in the fresh water tank can be prevented from flowing out through the tap water inlet 111.

In addition, one of the two second valves 140 is a normally open valve, and the other is a normally closed valve. Thus, when not in operation, the normally open valve remains in a normally open state, and the normally closed valve remains in a normally closed state, i.e., the flow path between the tap water inlet 111 and the water outlet 113 is cut off. In operation, the flow path between the tap water inlet 111 and the water outlet 113 can be opened by simply opening the normally closed valve. Thus, when both second valves 140 are available, only the normally closed valve needs to be operated, either to shut off or open the flow path between the tap water inlet 111 and the water outlet 113.

The first waterway assembly 110 is a waterway plate assembly, and the first waterway assembly 110 has a first chamber 114, a second chamber 115, and a third chamber 116. The tap water inlet 111 communicates with the first chamber 114. Two second valves 140 are provided, one of which communicates with the first chamber 114 and the third chamber 116, respectively, and the other of which communicates with the third chamber 116 and the second chamber 115, respectively. The water outlet 113 communicates with the second chamber 115. Referring to fig. 7, 9 to 11, the flow path of the water flow entering from the tap water inlet 111 is: the water flow entering from the tap water inlet 111 sequentially passes through the first chamber 114, the second valve 140, the third chamber 116, the second valve 140 and the second chamber 115, and then flows out from the water outlet 113, and the flow path is shown by arrows in fig. 7, 10 and 11.

More specifically, referring to fig. 4-7, 9-11, first waterway assembly 110 has a first valve pair interface 40 in communication with first chamber 114, a second valve pair interface 50 in communication with third chamber 116, a third valve pair interface 60 in communication with third chamber 116, and a fourth valve pair interface 70 in communication with second chamber 115. Two second valves 140, one of which is in communication with the first chamber 114 and the third chamber 116 through the first valve pair interface 40 and the second valve pair interface 50, respectively, referring to fig. 10; the other end communicates with the third chamber 116 and the second chamber 115 through the third valve pair interface 60 and the fourth valve pair interface 70, respectively, see fig. 11. The flow path of the water flow entering through the tap water inlet 111 is: tap water enters the first chamber 114 through the tap water inlet 111, see fig. 7; a second valve 140 is entered through the first valve interface 40, see fig. 10; through the second valve pair interface 50 into the third chamber 116, see fig. 10; through the third valve interface 60 into another second valve 140, see fig. 11; through the fourth valve pair interface 70 into the second chamber 115; out through the water outlet 113, see fig. 7.

Optionally, the second valve 140 is a solenoid valve, which is conveniently controlled by a control system. It will be appreciated that in other embodiments, the second valve is not limited to a solenoid valve, but may be other types of valves.

Referring to fig. 7, the water tank inlet 112 communicates with the second chamber 115. The water flow entering from the water inlet 112 of the water tank passes through the second chamber 115 and then flows out from the water outlet 113.

Of course, it is understood that in other possible embodiments, the number of second valves is not limited to two, but may be one, three, or more than three. Correspondingly, the structure of the first waterway assembly is correspondingly adjusted. For example, when the number of the second valves is one, the first waterway assembly has a first chamber and a second chamber. The tap water inlet is communicated with the first chamber. And two ends of the second valve are respectively communicated with the first chamber and the second chamber. The water inlet of the water tank is communicated with the second chamber. The water outlet is communicated with the second chamber. Therefore, the water flow entering from the tap water inlet sequentially passes through the first chamber, the second valve and the second chamber and then flows out from the water outlet. And water flow entering from the water inlet of the water tank flows out from the water outlet after passing through the second cavity.

Referring to fig. 4, 5 and 12, the water source switching mechanism 100 further has a water pressure monitoring assembly 150, and the water pressure monitoring assembly 150 is configured to monitor the water pressure in the first chamber 114. According to the monitoring result of the water pressure monitoring assembly 150, it can be more accurately known whether the water flow smoothly enters the first chamber 114.

Specifically, in the embodiment shown in fig. 9 and 12, first waterway assembly 110 has a water pressure monitoring port 117. The water pressure monitoring port 117 communicates with the first chamber 114. The water pressure monitoring assembly 150 interfaces with the water pressure monitoring port 117.

More specifically, referring to fig. 7, 9 and 12, the first chamber 114 includes a main flow region 1141 and a water pressure monitoring region 1142, with the water pressure monitoring port 117 being located on a side wall of the water pressure monitoring region 1142. Along the depth direction of the first chamber 114, the height of the water pressure monitoring area 1142 is greater than the height of the main flow area 1141, and the starting height h1 of the water pressure monitoring port 117 is higher than the height h2 of the main flow area 1141. Therefore, only when the water level in the first chamber 114 is greater than the main flow area 1141, the water pressure monitoring assembly 150 can monitor the change of the water pressure, so as to avoid the impact of the water flow to influence the monitoring result of the water pressure monitoring assembly 150, and to more accurately monitor whether the water flow smoothly enters the first chamber 114.

Optionally, the water source switching mechanism 100 further comprises a control assembly. The control assembly is configured to receive the monitoring result of the water pressure monitoring assembly 150 and to control the second valve 140 to be opened when the monitoring result reaches a preset water pressure value. It is understood that the control assembly described herein controls the second valve 140 to open, meaning that the second valve 140 is controlled to close to open. Of course, if the monitoring result does not reach the preset water pressure value, the normally open second valve 140 is closed, and then the normally open second valve 140 is controlled to be opened; if the monitoring result does not reach the preset water pressure value, the normally closed second valve 140 is closed, and the normally closed second valve 140 is controlled to be opened at the moment. Thus, when the monitoring result reaches the preset water pressure value, both the second valves 140 are controlled to be in an opened state. It will be appreciated that in a possible embodiment, the water source switching mechanism 100 may also share a control assembly with the drinking appliance as a whole.

Of course, if in another embodiment, there is only one second valve, the control component may control the second valve to open when the monitored result reaches the preset water pressure value.

Alternatively, the water tank 210 is a raw water tank. The water outlet 113 interfaces with the filter assembly. So that the water flowing out of the water outlet 113 is filtered through the filter assembly and reused.

Optionally, a booster pump is provided at the water outlet 113.

Further optionally, the drinking apparatus further comprises a clean water tank. The water purifying tank is internally provided with a water level monitoring mechanism. The control component is configured to receive the monitoring result of the water level monitoring mechanism, and control the booster pump to operate when the monitoring result is lower than a preset low water level value, so as to produce water, thereby ensuring the timely supply of purified water; when the monitoring result rises to a preset high water level value, the booster pump is controlled to stop running, so that excessive water in the water purifying tank is prevented from overflowing.

Still further, optionally, an anti-overflow electrode is provided in the clean water tank. The control assembly is further configured to receive a signal of whether the anti-overflow electrode is on, and when receiving the signal of whether the anti-overflow electrode is on, control the booster pump to stop running and control the second valve to be closed. Stopping operation of the booster pump and stopping water production, so that the continuous increase of purified water in the purified water tank is avoided, and the overflow of purified water in the purified water tank is further avoided; by controlling the second valve to be closed, the reverse flow of the purified water in the purified water tank is avoided, and the purified water flows out through the tap water inlet. Here, the second valve closing means that 2 second valves are closed to avoid a failure of one second valve, causing water to flow out through the tap water inlet.

Referring to fig. 3-7, 9 and 13, the water source switching mechanism 100 further includes a second waterway assembly 160, and a flush valve (not shown), a third valve 180 and a second seal cap 30. The second waterway assembly 160 has a waste inlet 161, a first waste outlet 162, and a second waste outlet 163. The first waste outlet 162 and the second waste outlet 163 are both in communication with the waste inlet 161, so that water flowing in through the waste inlet 161 can be discharged through the first waste outlet 162 or through the second waste outlet 163. A flush valve (not shown) is provided at the wastewater inlet 161. The first waste outlet 162 is adapted to communicate with the tank. The second waste outlet 163 is in communication with the external environment. Thus, the water flow entering through the waste water inlet 161 can flow out through the first waste water outlet 162 and flow into the water tank of the drinking water device, so that the water can be reused, and the waste of water resources is avoided. Of course, the water flow entering through the waste inlet 161 may also be discharged via the second waste outlet 163.

The third valve 180 is disposed at the first waste outlet 162. The third valve 180 is opened, and the water flow entering from the waste water inlet 161 can flow out through the first waste water outlet 162 and flow into the water tank of the drinking water device, so that the water flow can be reused, and the waste of water resources is avoided. The third valve 180 is closed so that the first waste 162 is closed to prevent water flow out through the first waste 162.

Optionally, referring to fig. 13 and 14, the third valve 180 has a third valve outlet 181. The water source switching mechanism 100 further includes a second adapter 80. One end of the second adapter 80 is abutted with the third valve water outlet 181 of the third valve 180, and the other end is abutted with the water tank water inlet 212 of the water tank.

Of course, the third valve 180 also has a third valve inlet 182, the third valve inlet 182 interfacing with the first waste outlet 162. Thus, water flow in the fourth chamber 164 may enter the third valve 180 through the third valve water inlet 182 and further into the water tank 210 through the second adapter 80.

Referring to fig. 3-7, 9 and 13, the second seal cap 30 is removably positioned at the second waste outlet 163. The second sealing cap 30 is closed at the second waste 163, and the second waste 163 is closed to prevent water from flowing out through the second waste 163. After unloading the second seal cap 30, the second waste outlet 163 is opened and water entering through the waste inlet 161 may optionally flow out through the second waste outlet 163. Further, the second waste outlet 163 is interfaced with a waste collection device or waste drain to collect or drain waste.

Accordingly, the arrangement of the second seal cap 30 and the third valve 180 allows for selection of whether the water flow entering through the waste inlet 161 is to be discharged through the first waste outlet 162 or through the second waste outlet 163, as desired.

More specifically, in the embodiments shown in fig. 3-7, 9 and 13, the height of the second waste 163 in the vertical direction is lower than the height of the first waste 162 in use. Thus, when the second sealing cap 30 is unloaded and the third valve water outlet 181 is opened, the waste water is discharged through the second waste water outlet 163.

The second waterway assembly 160 is a waterway plate assembly, and the second waterway assembly 160 has a fourth chamber 164. The waste inlet 161, the first waste outlet 162 and the second waste outlet 163 are all in communication with the fourth chamber 164. Thus, the water flowing in through the waste inlet 161 flows into the fourth chamber 164 and is discharged through the first waste outlet 162 or the second waste outlet 163.

Of course, it is understood that the structure of second waterway assembly 160 is not limited thereto, and the shape thereof may be adjusted. Of course, the second waterway assembly may also be a pipeline assembly.

In particular to the embodiment shown in fig. 4-7, first waterway assembly 110 and second waterway assembly 160 are integrally formed.

Specifically, the water source switching mechanism includes a first waterway half 118 and a second waterway half 119; the first waterway half 118 and the second waterway half 119 are butted to form the first waterway assembly 110 and the second waterway assembly 160.

In particular to the embodiment shown in fig. 4-7, first waterway half 118 and second waterway half 119 are butted by ultrasonic welding. It will be appreciated that in other embodiments, the first waterway half and the second waterway half may be further abutted by other means, and the first waterway assembly and the second waterway assembly may be formed after being abutted, and tightness of the abutted may be ensured.

It will be appreciated that in other embodiments, the first waterway assembly and the second waterway assembly may also be separately provided.

In the embodiment shown in fig. 1 and 2, the water tank 210 is detachable. Water is conveniently added to the water tank 210. Optionally, a valve is provided at the water tank water outlet 211. After the water tank 210 is installed, the valve is opened, so that water in the water tank 210 can flow out conveniently; after the water tank 210 is disassembled, the valve is closed, so that water in the water tank 210 is prevented from flowing out after the water tank 210 is disassembled.

In the embodiment shown in fig. 1 and 2, the first valve 120 and the third valve 180 are both positioned at the bottom side of the water tank 210, and the first valve 120 and the third valve 180 can be prevented from being erroneously operated by the protection of the water tank.
