[0041] A water purifier stores and purifies the water source so that users can directly drink clean water when using the water purifier. The water purifier has gradually become an indispensable small household appliance in people's daily lives, providing convenience for people to obtain water. In the past few decades, with the improvement of the living standards of Chinese people, the sales volume of water purifiers has increased year by year, and the safety and function issues of water purifiers have also attracted more and more attention.

[0042] Most traditional water purifiers are designed for a single water source and are difficult to adapt to the changes in the characteristics of different water sources. Especially when facing the switching of multiple water sources, their purification effect and water supply stability are often affected, and the usage scenarios are limited.

[0043] Refer to Figures 1 to 14 , the present application provides a water production device with multiple water source mode switching, including a main machine 100, a source water tank 200, a water inlet pipe 300, a water outlet pipe 400, and a solenoid valve 500.

[0044] The main machine 100 is provided with a water inlet 110 and a water outlet 120. The source water tank 200 includes a water tank 210 and a mounting seat 220. The water tank 210 is detachably connected to the main machine 100 through the mounting seat 220. The mounting seat 220 is provided with a first connecting pipe 221 and a second connecting pipe 222 that communicate with the inside of the water tank 210. The first connecting pipe 221 is cooperatively connected with the water inlet 110, and the second connecting pipe 222 is cooperatively connected with the water outlet 120. The water inlet pipe 300 is detachably installed at the water inlet 110, the water outlet pipe 400 is detachably installed at the water outlet 120, and the solenoid valve 500 is detachably installed on the main machine 100. The solenoid valve 500 is communicated with the water inlet 110 through a hose 510.

[0045] During use, after the inside of the water tank 210 is filled with water, it is installed on the main machine 100 through the mounting seat 220. The first connecting pipe 221 is connected to the water inlet 110, and the second connecting pipe 222 is connected to the water outlet 120, thereby realizing Figure 2 the water production device in the source water tank mode as shown; when both the water inlet pipe 300 and the water outlet pipe 400 are installed on the water inlet 110 and the water outlet 120, the water inlet pipe 300 can be connected to a water-containing container, a stream, a river, a lake, etc., thereby realizing Figure 5 the water production device in the external water pumping mode as shown; after the water inlet pipe 300 and the water outlet pipe 400 are installed on the water inlet 110 and the water outlet 120 of the main machine 100, the solenoid valve 500 is installed on the main machine 100 again. The solenoid valve 500 is connected to the water inlet 110 through the hose 510. In this way, by utilizing the high-pressure resistance performance of the solenoid valve 500, Figure 6 the water production device in the tap water connection mode as shown is realized. Through the detachable structure setting of the present application, the switching of three water inlet modes can be realized to adapt to the changes of different water sources, making the adaptability of the present application better and the applicable range wider.

[0046] Referring to Figure 4 、 Figure 7 、 Figure 8 In some embodiments, the mounting seat 220 is provided with a first assembly hole 223 and a second assembly hole 224. A first control valve 225 and a second control valve 226 are arranged inside the mounting seat 220. The first connecting pipe 221 is communicated with the first assembly hole 223 through the first control valve 225, and the second connecting pipe 222 is communicated with the second assembly hole 224 through the second control valve 226. A water outlet nozzle 212 and a water inlet nozzle 213 that communicate with the inside of the water tank are arranged at the bottom of the water tank 210. The water outlet nozzle 212 cooperates with the first assembly hole 223, and the water inlet nozzle 213 cooperates with the second assembly hole 224.

[0047] Specifically, the mounting base 220 is of a box structure. A first assembly hole 223 and a second assembly hole 224 with a through-hole structure are formed in the top of the mounting base 220. A cavity 211 for mating with the mounting base 220 is formed in the bottom of the water tank 210. The water outlet nozzle 212 and the water inlet nozzle 213 are both arranged in the cavity 211. During the installation process, the cavity 211 at the bottom of the water tank 210 mates with the mounting base 220, so that the water outlet nozzle 212 and the water inlet nozzle 213 are respectively inserted into the first assembly hole 223 and the second assembly hole 224, thereby realizing the mating connection between the water tank 210 and the mounting base 220. The first connecting pipe 221 and the second connecting pipe 222 on the mounting base 220 are respectively assembled into the water inlet 110 and the water outlet 120 to realize the connection between the mounting base 220 and the host 100.

[0048] In order to improve the connection performance between the mounting base 220 and the host 100, in some embodiments, slots 130 are formed above the water inlet 110 and above the water outlet 120 on the host 100. Hooks 227 are installed on the side plates of the mounting base 220 where the first connecting pipe 221 and the second connecting pipe 222 are arranged. The hooks 227 can cooperate with the slots 130. Thereby realizing the detachable connection between the mounting base 220 and the host 100.

[0049] In some embodiments, the first control valve 225 includes an outer sleeve 2250, an inner sleeve 2251 and a valve core 2252. One end of the outer sleeve 2250 is of an open structure and the other end is of a closed structure. The first connecting pipe 221 is connected to the closed end of the outer sleeve 2250. Both ends of the inner sleeve 2251 are of open structures. The inner sleeve 2251 is assembled in the outer sleeve 2250. One end of the inner sleeve 2251 extends into the interior of the outer sleeve 2250 and the other end is located outside the open end of the outer sleeve 2250. The end of the inner sleeve 2251 extending into the interior of the outer sleeve 2250 is spaced from the closed end of the outer sleeve 2250. The valve core 2252 includes a movable column 22520 and a spring 22521. A sealing pad 22522 is arranged at one end of the movable column 22520, and a limit end 22523 is arranged at the other end of the movable column 22520. The movable column 22520 is arranged in the inner sleeve 2251. The spring 22521 is sleeved on the movable column 22520. One end of the spring 22521 abuts against the closed end of the outer sleeve 2250 and the other end abuts against the limit end 22523. The sealing pad 22522 is pressed against the end of the inner sleeve 2251 extending into the interior of the outer sleeve 2250 by the elastic force of the spring 22521. A cross docking head 22524 is arranged on the limit end 22523, and the cross docking head 22524 is inserted into the water outlet nozzle 212.

[0050] The second control valve 226 is the same as the first control valve 225. The outer sleeve of the second control valve 226 is communicated with the second connecting pipe 222, and the docking head of the second control valve 226 is inserted into the water inlet nozzle 213.

[0051] Specifically, the upper end of the outer sleeve 2250 is open and the lower end is closed. The first connecting pipe 221 is horizontally connected to the lower end of the outer sleeve 2250 and extends out from the side of the mounting base 220. The water tank 210 is fitted with the mounting base 220. After the water outlet nozzle 212 on the water tank 210 is inserted into the first assembly hole 223, the cross docking head 22524 on the first control valve 225 will be inserted into the water outlet nozzle 212. At the same time, the water tank 210 will push the movable column 22520 downward under its own gravity, and the spring 22521 will be compressed between the limit end 22523 and the closed end of the outer sleeve 2250. When the movable column 22520 is pressed downward, the gasket 22522 will separate from one end of the inner sleeve 2251 located inside the outer sleeve 2250, so that the inner sleeve 2251 communicates with the outer sleeve 2250. At this time, the water in the water tank 210 will flow out from the water outlet nozzle 212, enter the outer sleeve 2250 through the inner sleeve 2251, and then enter the main machine 100 through the first connecting pipe 221. The water filtered by the main machine 100 flows back into the outer sleeve 2250 of the second control valve 226 through the second connecting pipe 222, then passes through the inner sleeve 2251 of the second control valve 226, and finally enters the water tank 210 through the water inlet nozzle 213. When the water tank 210 is separated from the mounting base 220, since the pressure on the movable column 22520 is released, the compressed spring 22521 will rebound at this time, driving the movable column 22520 to move upward, so that the gasket 22522 on the movable column 22520 is pressed against one end of the inner sleeve 2251 located inside the outer sleeve 2250, so as to close the inner sleeve 2251 and the outer sleeve 2250 and play a role in stopping water. Therefore, in this application, the first control valve 225 and the second control valve 226 are arranged inside the mounting base 220, which can cooperate with the water tank 210 to realize automatic water supply and water stop. When the water tank 210 is installed on the mounting base 220, it will automatically supply water, and when the water tank 210 is separated from the mounting base 220, it will automatically stop water. Compared with the scheme of realizing automatic water supply and water stop by electronic means, the structure of realizing automatic water supply and water stop by pure mechanical structure in this application is more robust and durable.

[0052] In some embodiments, the limit end 22523 is a cross structure, and the outer end of the inner sleeve 2251 located outside the outer sleeve 2250 is provided with avoidance grooves 22510 distributed in a cross shape. The avoidance grooves 22510 extend along the length direction of the inner sleeve 2251, and the limit end 22523 is fitted in the avoidance grooves 22510 of the inner sleeve 2251. The avoidance grooves 22510 play a role in limiting the movable column 22520. After the limit end 22523 is assembled into the avoidance grooves 22510, the limit end 22523 can only move up and down within the stroke range of the avoidance grooves 22510 and will not rotate left and right, thereby improving the lifting stability of the movable column 22520.

[0053] ​In some embodiments, the movable column 22520 has a cross-columnar structure. This can prevent the gasket 22522 from shrinking.

[0054] In some embodiments, the outer sleeve 2250 is provided with a first connecting plate 22500 extending outward, the inner sleeve 2251 is provided with a second connecting plate 22510 extending outward, and a connecting column is provided inside the mounting seat 220. The first connecting plate 22500 and the second connecting plate 22510 cooperate and are fixed on the connecting column.

[0055] Specifically, two connecting columns are provided on both sides of the first assembly hole 223 inside the mounting seat 220. Both the first connecting plate 22500 and the second connecting plate 22510 of the first control valve 225 are fixed on the two connecting columns by bolts. Similarly, since the structure of the second control valve 226 is the same as that of the first control valve 225, the second control valve 226 is also connected to the connecting columns on both sides of the second assembly hole 224 in the same way.

[0056] In some embodiments, the second connecting plate 22510 is provided with a support sleeve 22511. The support sleeve 22511 surrounds the periphery of one end of the inner sleeve 2251 where the avoidance groove 22510 is provided. The support sleeve 22511 is concentric with the inner sleeve 2251, and a sealing sleeve 22512 is installed on the support sleeve 22511.

[0057] After the water tank 210 is fitted onto the mounting seat 220, the water outlet nozzle 212 on the water tank 210 is inserted into the first assembly hole 223 and the sealing sleeve 22512 on the first control valve 225. The sealing sleeve 22512 functions to seal and prevent the water coming out of the water tank 210 from flowing out from the side of the water outlet nozzle 212. Similarly, the water inlet nozzle 213 on the water tank 210 is inserted into the second assembly hole 224 and the sealing sleeve on the second control valve 226. The sealing sleeve on the second control valve 226 also functions to prevent the water flowing into the water inlet nozzle 213 from the side of the inner sleeve 2251 from flowing out.

[0058] In some embodiments, the water tank 210 is provided with a handle 214, the handle 214 is provided with a clamping plate 215, and the main body 100 is provided with a card slot 140. The clamping plate 215 is inserted into the card slot 140.

[0059] Specifically, two card slots 140 are provided on the upper part of the main body 100, and two clamping plates 215 are provided on the handle 214 of the water tank 210. After the water tank 210 is connected to the water inlet 110 and the water outlet 120 at the bottom of the main body 100 through the mounting seat 220, the two clamping plates 215 on the handle 214 are respectively inserted into the two card slots 140. In this way, the upper and lower ends of the water tank 210 are more stably connected to the main body 100.
