[0061] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0062] like Figure 1 and Figure 2As shown, this embodiment provides a solenoid valve 1 for a water purification device, the solenoid valve 1 includes a main body 11 and a water nozzle 12, the water nozzle 12 is sleeved on the water outlet 112 of the main body, the solenoid valve 1 also includes a first sealing member 13, the first sealing member 13 is arranged between the main body 11 and the water nozzle 12, and the first sealing member 13 is sealed and connected to the main body 11 and the water nozzle 12 respectively; the water retaining member 19 is rotatably connected to the water outlet 121 of the water nozzle through a rotating shaft, and the extension direction of the water outlet 121 of the water nozzle near the water retaining member 19 is not parallel to the extension direction of the rotating shaft, so that the water retaining member 19 can switch between closing the water outlet 121 of the water nozzle and opening the water outlet 121 of the water nozzle. Specifically, the first sealing member 13 can effectively seal the water spout 12 and the water outlet 112 of the main body, so that the external atmospheric pressure cannot enter the water spout 12, thereby forming a vacuum inside the water spout 12, preventing the water outlet 121 of the water spout from dripping, reducing the possibility of scalding the user, and improving the user experience. In addition, the water can be sealed inside the water spout 12 by the water retaining member 19, thereby preventing the water in the water spout 12 from dripping. Specifically, when the user needs to use water, the water retaining member 19 allows the water retaining plate to rotate around the rotating shaft under the action of the water flow, so that the water retaining member 19 opens the water outlet 121 of the water spout, and at this time, the water source can flow from the main body 11 into the water spout 12 and flow out from the water outlet 121 of the water spout. When the user does not need to use water, the projection of the water stop 19 completely covers the water outlet 121 of the water nozzle in the axial direction of the area near the water baffle plate, so that the water stop 19 can close the water outlet 121 of the water nozzle to prevent dripping in the water nozzle 12, thereby reducing the risk of scalding the user and improving the user experience.

[0063] It should be specifically stated that the diameter of the first seal 13 close to the body 11 is smaller than the diameter of the first seal 13 close to the water spout 12, and the first seal 13 is preferably trumpet-shaped. Specifically, the inner wall of the water outlet 112 of the body is truncated cone-shaped, that is, it is a structure that is small at the top and large at the bottom. The first seal 13 is also truncated cone-shaped, that is, it is also a structure that is small at the top and large at the bottom, and the structure of the first seal 13 that is small at the top and large at the bottom fits tightly with the inner wall surface of the larger diameter in the water outlet 112 of the body, so that the water from the water outlet 112 of the body to the water spout 12 is effectively filled through the first seal 13, so that no excess air is generated in the water spout 12, avoiding the problem of dripping from the water outlet 121 of the water spout.

[0064] In this embodiment, the material of the first sealing member 13 is rubber material, and in other embodiments, the material of the first sealing member 13 is not limited. In addition, the blocking member 16 is provided at the water outlet 121 of the faucet, and the area of ​​the blocking member 16 close to the moving member 14 is smaller than the area of ​​the blocking member 16 close to the water outlet 121 of the faucet, thereby effectively preventing the blocking member 16 from falling off, and improving the effect of the blocking member 16 in blocking the water outlet 121 of the faucet, thereby avoiding the problem of dripping.

[0065] like Figure 1 As shown, the solenoid valve 1 also includes a reset spring 21, and the reset spring 21 is arranged in the area of ​​the water retaining member 19 close to the rotating shaft, so that when the water flow impact is small or there is no water flow, the reset spring 21 can drive the water retaining member 19 to reset quickly, so that the water in the water spout 12 is sealed inside the water spout 12, further reducing the risk of scalding the user and improving the user experience.

[0066] like Figure 1 As shown, the solenoid valve 1 further includes a moving part 14, a driving part 15 and a blocking part 16. The water inlet 111 of the body is connected to the water outlet 112 of the body through a connecting passage 116. The moving part 14, the driving part 15 and the blocking part 16 are arranged in the body 11. A first magnetic surface 141 and a second magnetic surface 151 are respectively arranged on the surface of the moving part 14 facing the driving part 15 and the surface of the driving part 15 facing the moving part 14. The end of the moving part 14 away from the driving part 15 is connected to the blocking part 16. The first magnetic surface 141 and the second magnetic surface 151 are magnetically matched to enable the blocking part 16 to move in opening or closing the connecting passage 116. Specifically, through the magnetic matching of the first magnetic surface 141 and the second magnetic surface 151, the moving part 14 can move relative to the driving part 15, and then the blocking part 16 can be driven by the moving part 14 to move in the connecting passage 116, so as to achieve the connection or closing of the water inlet 111 of the body and the water outlet 112 of the body. Furthermore, when the user needs to get water from the water outlet 121 of the water spout, the blocking member 16 opens the connecting channel 116, so that the water outlet 112 of the main body is connected with the water inlet of the main body 11, so that the water inlet 111 of the main body and the water spout 12 are connected, and the water passes through the water inlet 111 of the main body and the connecting channel 116 in turn to reach the water outlet 112 of the main body, and can flow out from the water outlet 121 of the water spout; when the user does not need to get water, the blocking member 16 closes the connecting channel 116, so that the water inlet 111 of the main body and the water outlet 112 of the main body are closed, so that the water inlet 111 of the main body and the water spout 12 are closed, so that water cannot flow out from the water outlet 121 of the water spout, thereby preventing dripping or flowing out in streams, reducing the risk of scalding the user and improving the safety of user use.

[0067] When it is necessary to explain in detail, the magnetic cooperation of the first magnetic surface 141 and the second magnetic surface 151 means that the magnetic forces of the first magnetic surface 141 and the second magnetic surface 151 can be opposite, so that the first magnetic surface 141 and the second magnetic surface 151 generate attraction when power is turned on, so that the first magnetic surface 141 and the second magnetic surface 151 move in the direction of approaching each other; the magnetic forces of the first magnetic surface 141 and the second magnetic surface 151 can also be the same, so that the first magnetic surface 141 and the second magnetic surface 151 generate repulsion when power is turned on, so that the first magnetic surface 141 and the second magnetic surface 151 move in the direction away from each other. In short, the magnetic cooperation of the first magnetic surface 141 and the second magnetic surface 151 refers to the movement relationship between the first magnetic surface 141 and the second magnetic surface 151 generated by utilizing the magnetic relationship between the first magnetic surface 141 and the second magnetic surface 151.

[0068] In this embodiment, the driving member 15 is a coil and the moving member 14 is an armature. The coil has magnetism when powered, and the magnetism is opposite to that of the armature. In other embodiments, the types of the driving member 15 and the moving member 14 can be adjusted according to actual needs, and the types of the driving member 15 and the moving member 14 are not specifically limited here.

[0069] like Figure 1 As shown, the driving member 15 is provided with a first accommodating cavity 152, and the outer wall surface of the moving member 14 is slidably matched with the inner wall surface of the first accommodating cavity 152; wherein the extension direction of the first accommodating cavity 152 is the same as the movement direction of the blocking member 16; or, the moving member 14 is provided with a second accommodating cavity, and the outer wall surface of the driving member 15 is slidably matched with the inner wall surface of the second accommodating cavity; wherein the extension direction of the second accommodating cavity is the same as the movement direction of the blocking member 16. With the above-mentioned structural form, the first accommodating cavity 152 or the second accommodating cavity can provide guidance for the movement of the moving member 14, so that the moving member 14 can move in a preset direction, and then can drive the blocking member 16 to move in a preset direction, thereby improving the stability and reliability of the movement of the blocking member 16, and improving the stability and reliability of the movement of the blocking member 16 in the connecting channel 116, and then can be conducive to the stability and reliability of closing the connecting channel 116 when the user does not receive water, further reducing the possibility of the user being scalded.

[0070] In this embodiment, the driving member 15 defines a first accommodating cavity 152 , and the outer wall surface of the moving member 14 is slidably matched with the first accommodating cavity 152 .

[0071] The magnetism of the first magnetic surface 141 and the second magnetic surface 151 are opposite. When the blocking member 16 closes the connecting channel 116, the first magnetic surface 141 and the second magnetic surface 151 have a gap 17 in the movement direction of the blocking member 16; specifically, when the first magnetic surface 141 and the second magnetic surface 151 are not energized, there is a gap 17 between the first magnetic surface 141 and the second magnetic surface 151; after power is supplied, the magnetism generated by each other is opposite, so that the first magnetic surface 141 and the second magnetic surface 151 move towards each other, so that the gap 17 is reduced, so that the moving member 14 can drive the blocking member 16 to move.

[0072] The second magnetic surface 151 is arranged at the bottom of the first accommodating cavity 152, and the first magnetic surface 141 is arranged at one end of the moving member 14 accommodated in the first accommodating cavity 152; or, the first magnetic surface 141 is arranged at the bottom of the second accommodating cavity, and the second magnetic surface 151 is arranged at one end of the driving member 15 accommodated in the second accommodating cavity. The above structural form improves the compactness of the overall structure of the solenoid valve 1.

[0073] In this embodiment, a first accommodating cavity 152 is opened on the coil, one end of the armature extends into the first accommodating cavity 152 from the opening of the first accommodating cavity 152, and a gap 17 is provided between the bottom of the first accommodating cavity 152 and the end face of the armature extending into the first accommodating cavity 152.

[0074] The solenoid valve 1 further comprises an elastic member 18 , which is disposed in the gap 17 , and whose opposite ends are respectively connected to the first magnetic surface 141 and the second magnetic surface 151 , thereby improving the efficiency of the moving member 14 returning to the initial position through the elastic member 18 .

[0075] See also Figure 1 It is understood that the elastic member 18 includes an elastic portion 181 and a buffer portion 182, the buffer portion 182 is connected to one of the first magnetic surface 141 and the second magnetic surface 151, one end of the elastic portion 181 is connected to the buffer portion 182, and the other end of the elastic portion 181 is connected to the other of the first magnetic surface 141 and the second magnetic surface 151. The above-mentioned structural form prevents the moving member 14 from generating a large impact force when moving, thereby helping to reduce the possibility of the electromagnetic valve 1 generating noise, and improves the service life of the moving member 14 and the driving member 15, thereby helping to improve the overall service life of the electromagnetic valve 1.

[0076] In this embodiment, the buffer portion 182 is connected to the first magnetic surface 141, and both ends of the elastic portion 181 are respectively connected to the buffer portion 182 and the second magnetic surface 151. In other embodiments, the connection positions of the buffer portion 182 and the elastic portion 181 can be adjusted according to actual needs, and are not specifically limited here.

[0077] like Figure 1As shown, the solenoid valve 1 further includes a guide rib 20, which is connected to at least part of the surface of the water nozzle 12, and the extension direction of the guide rib 20 is the same as the extension direction of the surface connected to the guide rib 20. With the above-mentioned structural form, the guide rib 20 can prevent the water flowing out of the water outlet 121 of the water nozzle from splashing, thereby helping to avoid splashing to the user and causing scalding, thereby improving the user's experience.

[0078] It should be specifically explained that there are multiple guide ribs 20, and the multiple guide ribs 20 are arranged at intervals in the circumferential direction of the water outlet 121 of the faucet.

[0079] like Figure 1 As shown, the body 11 includes a first body 113 , a second body 114 and a second sealing member 115 . The first body 113 and the second body 114 are sealed and connected via the second sealing member 115 , thereby preventing water from overflowing and facilitating improving the sealing performance of the body 11 as a whole.

[0080] The solenoid valve 1 further includes a filter 22, which is disposed at the water inlet 111 of the body and is used to filter the water source of the water inlet 111 of the body. Specifically, the filter 22 is sleeved on the water inlet 111 of the body, and a filter hole 221 is provided on the filter 22 for filtering impurities. With the above-mentioned structural form, some foreign matter can be intercepted by the filter 22 to prevent the moving part 14 from being stuck and unable to move, thereby facilitating the stability and reliability of the movement of the moving part 14, and further facilitating the stability and reliability of the movement of the blocking part 16.

[0081] The present embodiment also provides a water purification device, which includes a solenoid valve 1. The solenoid valve 1 is applied to the water purification device by adopting the above-mentioned structural form, so that the first sealing member 13 can effectively seal the water spout 12 and the water outlet 112 of the main body, so that the atmospheric pressure of the outside cannot enter the water spout 12, so that a vacuum can be formed inside the water spout 12, and the water outlet 121 of the water spout is prevented from dripping, which reduces the possibility of scalding the user and improves the user experience. In addition, the water can be sealed inside the water spout 12 by the water retaining member 19, so that the water in the water spout 12 can be prevented from dripping. Specifically, when the user needs to use water, the water retaining member 19 allows the water retaining plate to rotate around the rotating shaft under the action of the water flow, so that the water retaining member 19 opens the water outlet 121 of the water spout, and the water source can flow from the main body 11 into the water spout 12 and flow out from the water outlet 121 of the water spout. When the user does not need to use water, the projection of the water stop 19 completely covers the water outlet 121 of the water nozzle in the axial direction of the area near the water baffle plate, so that the water stop 19 can close the water outlet 121 of the water nozzle to prevent dripping in the water nozzle 12, thereby reducing the risk of scalding the user and improving the user experience.
