[0074] like Figure 1 As shown, in this embodiment, the blocking member includes a first driving part and a first blocking part, the first blocking part is arranged at the first outlet, the first driving part is connected to the first blocking part, and is used to drive the first blocking part to move in a direction close to or away from the first outlet, and is used to control the opening and closing of the first accommodating chamber, and the blocking member also includes a second driving part and a second blocking part, the second blocking part is arranged at the second outlet, the second driving part is connected to the second blocking part, and is used to drive the second blocking part to move in a direction close to or away from the second outlet, and is used to control the opening and closing of the second accommodating chamber. With the above-mentioned structural form, the first driving part drives the first blocking part to move, so that the first blocking part can open and close the first accommodating chamber, and further realize the opening and closing of the first inlet and the first outlet; the second driving part drives the second blocking part to move, so that the second blocking part can open and close the first accommodating chamber, and further realize the opening and closing of the second inlet and the second outlet.

[0075] There are several implementations for driving the first blocking part and the second blocking part.

[0077] When it is necessary to explain in detail, the magnetic coordination of the first magnetic surface and the second magnetic surface means that the magnetic forces of the first magnetic surface and the second magnetic surface can be opposite, so that the first magnetic surface and the second magnetic surface generate attraction when power is turned on, so that the first magnetic surface and the second magnetic surface move in the direction of approaching each other; the magnetic forces of the first magnetic surface and the second magnetic surface can also be the same, so that the first magnetic surface and the second magnetic surface generate repulsion when power is turned on, so that the first magnetic surface and the second magnetic surface move in the direction of moving away from each other. In short, the magnetic coordination of the first magnetic surface and the second magnetic surface refers to the motion relationship between the first magnetic surface and the second magnetic surface generated by utilizing the magnetic relationship between the first magnetic surface and the second magnetic surface. The same is true for the magnetic coordination of the third magnetic surface and the fourth magnetic surface.

[0078] There are several implementations for the first drive unit and the second drive unit.

[0085] The area of ​​the first blocking part close to the first outlet is larger than the area of ​​the first blocking part close to the first driving part. The above structure can prevent the first blocking part from falling off from the first accommodating cavity, and the above structure improves the stability and reliability of the first blocking part closing the first accommodating cavity.

[0086] The area of ​​the second blocking part close to the second outlet is larger than the area of ​​the second blocking part close to the second driving part. The above structure can prevent the second blocking part from falling off from the second accommodating cavity, and the above structure improves the stability and reliability of the second blocking part closing the second accommodating cavity.

[0087] There are several implementation methods for the solenoid valve. In a first implementation method, the solenoid valve also includes a first filter element, which is disposed at the first inlet and is used to filter water at the first inlet; in a second implementation method, the solenoid valve also includes a second filter element, which is disposed at the second inlet and is used to filter water at the second inlet; in a third implementation method, the solenoid valve also includes a first filter element, which is disposed at the first inlet and is used to filter water at the first inlet, and the solenoid valve also includes a second filter element, which is disposed at the second inlet and is used to filter water at the second inlet.

[0088] like Figure 1 As shown, in this embodiment, the solenoid valve further includes a first filter element, which is disposed at the first inlet and is used to filter water at the first inlet, and the solenoid valve further includes a second filter element, which is disposed at the second inlet and is used to filter water at the second inlet. With the above-mentioned structural form, the first water inlet and the second water inlet are filtered, so that some foreign matter can be intercepted by the first filter element and the second filter element, preventing the first blocking part and the second blocking part from being stuck and unable to move, thereby facilitating the stability and reliability of the movement of the first blocking part and the second blocking part.

[0089] This embodiment also provides a water purification device, which includes a solenoid valve. With the above-mentioned structural form, the blocking member moves in the first accommodating chamber and the second accommodating chamber to achieve the connection or closure between the first inlet and the first outlet and between the second inlet and the second outlet. Further, when the user needs to receive water from the outlet of the solenoid valve, the blocking member located in the first accommodating chamber opens the first accommodating chamber, so that the first inlet and the first outlet are connected, and at this time, the water flows out from the outlet of the solenoid valve after passing through the first inlet, the first accommodating chamber and the first outlet in sequence, so that the user can receive water from the outlet of the solenoid valve; the blocking member located in the second accommodating chamber opens the second accommodating chamber, so that the second inlet and the second outlet are connected, and at this time, the water flows out from the outlet of the solenoid valve after passing through the second inlet, the second accommodating chamber and the second outlet in sequence, so that the user can receive water from the outlet of the solenoid valve. In addition, the blocking member located in the first accommodating chamber opens the first accommodating chamber, so that the first outlet is connected to the first inlet and the exhaust hole at the same time, so that when the first outlet stops releasing water, the atmospheric pressure will also instantly release the water in the first accommodating chamber, thereby making it possible for no residual water to be contained in the first accommodating chamber, thereby ensuring that the first outlet will not drip, and reducing the risk of scalding the user. The blocking member located in the second accommodating chamber opens the second accommodating chamber, so that the second outlet is connected to the second inlet and the exhaust hole at the same time, so that when the second outlet stops releasing water, the atmospheric pressure will also instantly release the water in the second accommodating chamber, thereby making it possible for no residual water to be contained in the second accommodating chamber, thereby ensuring that the second outlet will not drip, and reducing the risk of scalding the user.

[0090] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
