[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. Since the operation of the solenoid valve is controlled by the on and off of the winding coil, the solenoid valve is used in an environment where there is a power outage, that is, the winding coil cannot be energized. In this way, the solenoid valve will be in a closed state driven by the core spring, so that the flow path of the equipment equipped with the solenoid valve cannot be opened. Utility Model Content

[0003] In view of this, it is necessary to provide a solenoid valve and a water dispenser that can solve the above technical problems.

[0004] In order to solve the above technical problems, this application provides the following technical solutions:

[0005] A solenoid valve, characterized in that the solenoid valve comprises:

[0006] a valve body, forming a valve port;

[0007] The core assembly comprises a movable core and a fixed core arranged face to face, wherein the movable core can make a reciprocating motion relative to the fixed core to control the on / off of the valve port;

[0008] A connecting rod passes through the fixed iron core and is inserted into the movable iron core along the movement direction of the movable iron core, wherein a first limit piece is provided on the connecting rod, the first limit piece is provided in the movable iron core and can abut against the movable iron core, and the connecting rod can drive the movable iron core to move toward the fixed iron core through the first limit piece, so that the movable iron core releases the blockage of the valve port.

[0009] It can be understood that the connecting rod is used to drive the movable iron core to move toward the fixed iron core, so as to release the blocking of the valve port by the movable iron core, so that once the solenoid valve is powered off during use, people can manually pull the connecting rod to drive the movable iron core to open the valve port. In this way, the flow path controlled by the solenoid valve can be opened to meet emergency needs. At the same time, since the connecting rod and the movable iron core are limited by the first limiting member, the connecting rod can pass through the movable iron core and be limited by the first limiting member to achieve assembly between it and the movable iron core. In this way, the coordination between the connecting rod and the movable iron core can be facilitated.

[0010] In one embodiment, the first stopper is configured as a first retaining ring, and the first retaining ring is connected to the connecting rod in a clamping manner;

[0011] Wherein, a step surface is formed on the movable iron core, and the first retaining ring can abut against the step surface.

[0012] It can be understood that the first retaining ring is connected to the connecting rod in a clamping manner, and the first retaining ring can abut against the step surface, so that the assembly of the connecting rod on the movable iron core can be facilitated.

[0013] In one embodiment, the connecting rod is further provided with a second limiting member, which is provided on the outer side of the fixed iron core and is used to limit the depth of the connecting rod inserted into the movable iron core;

[0014] The maximum movement stroke of the connecting rod when it moves relative to the fixed iron core is greater than or equal to the movement stroke of the movable iron core when it moves relative to the fixed iron core.

[0015] It can be understood that the second limit member is used to limit the depth of the connecting rod inserted into the movable iron core. In this way, the maximum stroke of the connecting rod when moving relative to the fixed iron core can be limited, so that the connecting rod is at least partially on the outside of the fixed iron core. In this way, it is convenient for the subsequent pulling and driving of the connecting rod; and the maximum movement stroke of the connecting rod when it moves relative to the fixed iron core is greater than or equal to the movement stroke of the movable iron core when it moves relative to the fixed iron core. The setting of the connecting rod will not affect the blocking of the valve port by the movable iron core, thereby ensuring that the solenoid valve can be used normally when the power is on.

[0016] In one of the embodiments, the solenoid valve further includes a sealing assembly, which is disposed on a portion of the connecting rod located inside the fixed iron core and is used to assemble and seal the connecting rod and the fixed iron core.

[0017] In one embodiment, the sealing assembly includes a first sealing ring, a gasket, a second sealing ring and a plug. Along the movement direction of the movable iron core, the first sealing ring, the gasket, the second sealing ring and the plug are sequentially mounted on the connecting rod, and the first sealing ring and the second sealing ring are deformed under pressure.

[0018] It can be understood that the first sealing ring and the second sealing ring are used to achieve the assembly seal between the connecting rod and the fixed iron core, so that the assembly seal between the connecting rod and the fixed iron core can be ensured to avoid leakage.

[0019] In one of the embodiments, the solenoid valve further includes a gland, which is threadably connected to the fixed core and is used to limit the sealing assembly to the fixed core.

[0021] In one embodiment, the solenoid valve further comprises a magnetic isolation tube, and the magnetic isolation tube is fixedly connected to the valve body;

[0022] Wherein, the fixed iron core is at least partially inserted into the magnetic isolation tube and connected to the magnetic isolation tube, and the movable iron core is movably installed in the magnetic isolation tube.

[0023] In one of the embodiments, the solenoid valve further includes an elastic member, which is sleeved on the movable iron core and respectively abuts against the magnetic isolation tube and the movable iron core, so as to drive the movable iron core to elastically return to its original position.

[0024] In one embodiment, the solenoid valve further includes a diaphragm, which is at least partially disposed in the movable iron core and connected to the movable iron core, and the movable iron core can be pressed against the valve port edge of the valve port through the diaphragm to seal the valve port.

[0025] The present application also seeks protection for a water dispenser, comprising the solenoid valve described above.

[0026] Compared with the prior art, the present application has the following advantages:

[0027] The solenoid valve and water dispenser for which protection is sought in the present application utilize a connecting rod to drive the movable iron core to move toward the fixed iron core, thereby releasing the blockage of the valve port by the movable iron core, so that if a power outage occurs during the use of the solenoid valve, people can manually pull up the connecting rod to drive the movable iron core to open the valve port, thereby opening the flow path controlled by the solenoid valve to meet emergency needs; at the same time, since the connecting rod and the movable iron core are limited by a first limiting member, the connecting rod can pass through the movable iron core and be limited by the first limiting member to achieve assembly between the connecting rod and the movable iron core, thereby facilitating the coordination between the connecting rod and the movable iron core.

[0037] The solenoid valve 100 for which protection is requested in this application is used in a water dispenser.

[0038] like Figure 1 to Figure 2 As shown, the solenoid valve 100 provided in one embodiment of the present application includes a valve body 10, an iron core assembly 20 and a connecting rod 30, wherein the valve body 10 is formed with a valve port 11; the iron core assembly 20 includes a movable iron core 21 and a fixed iron core 22 arranged face to face, wherein the movable iron core 21 can make a reciprocating motion relative to the fixed iron core 22 to control the on / off of the valve port 11; the connecting rod 30 passes through the fixed iron core 22 and is inserted into the movable iron core 21 along the moving direction of the movable iron core 21, wherein a first stopper 31 is provided on the connecting rod 30, wherein the first stopper 31 is provided in the movable iron core 21 and can collide with the movable iron core 21, and the connecting rod 30 can drive the movable iron core 21 to move toward the fixed iron core 22 through the first stopper 31, so that the movable iron core 21 releases the blocking of the valve port 11. That is to say, when the solenoid valve 100 of the present application is working, the connecting rod 30 can be used to control the on / off of the valve port 11.

[0039] It can be understood that the connecting rod 30 is used to drive the movable iron core 21 to move toward the fixed iron core 22, so as to release the blockage of the valve port 11 by the movable iron core 21, so that once the solenoid valve 100 is powered off during use, people can manually pull up the connecting rod 30 to drive the movable iron core 21 to open the valve port 11. In this way, the flow path controlled by the solenoid valve 100 can be opened to meet emergency needs; at the same time, since the connecting rod 30 and the movable iron core 21 are limited by the first limiting member 31, the connecting rod 30 can pass through the movable iron core 21 and be limited by the first limiting member 31 to achieve assembly between it and the movable iron core 21, so that the coordination between the connecting rod 30 and the movable iron core 21 can be facilitated.

[0040] like Figure 1 , Figure 2As shown, in one embodiment, the first stopper 31 is configured as a first retaining ring, and the first retaining ring is connected to the connecting rod 30 in a snap-fit ​​manner; wherein, a step surface 211 is formed on the movable iron core 21, and the first retaining ring can abut against the step surface 211. In other words, the first retaining ring is connected to the connecting rod 30 in a snap-fit ​​manner, and the first retaining ring can abut against the step surface 211, so that the assembly of the connecting rod 30 on the movable iron core 21 can be facilitated. It should be noted that the first stopper 31 is not limited to being connected to the connecting rod 30 in a snap-fit ​​manner. For those skilled in the art, the first stopper 31 can also be connected to the connecting rod 30 in a welding manner, which will not be elaborated here.

[0041] like Figure 1 , Figure 2 As shown, in one embodiment, a second limit member 32 is further provided on the connecting rod 30, and the second limit member 32 is provided on the outer side of the fixed iron core 22, and is used to limit the depth of the connecting rod 30 inserted into the movable iron core 21. That is to say, the second limit member 32 is used to limit the depth of the connecting rod 30 inserted into the movable iron core 21. In this way, the maximum stroke of the connecting rod 30 when moving relative to the fixed iron core 22 can be limited, so that the connecting rod 30 is at least partially on the outer side of the fixed iron core 22, so that the subsequent pulling and driving of the connecting rod 30 can be facilitated; wherein, the maximum movement stroke of the connecting rod 30 when moving relative to the fixed iron core 22 is greater than or equal to the movement stroke of the movable iron core 21 when moving relative to the fixed iron core 22, so that the setting of the connecting rod 30 will not affect the blocking of the valve port 11 by the movable iron core 21, and the solenoid valve 100 can be used normally when powered on.

[0042] In this embodiment, the second stopper 32 is configured as a second retaining ring, and the second retaining ring is connected to the connecting rod 30 in a clamping manner. It should be noted that the second stopper 32 is not limited to being connected to the connecting rod 30 in a clamping manner. For those skilled in the art, the second stopper 32 can also be connected to the connecting rod 30 in a welding manner, which will not be elaborated here.

[0043] like Figure 1 , Figure 2 As shown, in one embodiment, the solenoid valve 100 further includes a sealing assembly 40 , which is disposed on a portion of the connecting rod 30 located inside the fixed iron core 22 , and is used to assemble and seal the connecting rod 30 and the fixed iron core 22 .

[0044] In this embodiment, the sealing assembly 40 includes a first sealing ring 41, a gasket 42, a second sealing ring 43 and a plug 44. The first sealing ring 41, the gasket 42, the second sealing ring 43 and the plug 44 are sequentially mounted on the connecting rod 30 along the moving direction of the movable iron core 21, and the first sealing ring 41 and the second sealing ring 43 are deformed under pressure. The first sealing ring 41 and the second sealing ring 43 are used to realize the assembly seal between the connecting rod 30 and the fixed iron core 22, so that the assembly seal between the connecting rod 30 and the fixed iron core 22 can be ensured to avoid leakage.

[0045] like Figure 1 , Figure 2 As shown, in one embodiment, the solenoid valve 100 further includes a gland 50, which is connected to the fixed core 22 in a threaded manner, and is used to limit the sealing assembly 40 to the fixed core 22. In other words, the gland 50 is connected to the fixed core 22 in a threaded manner, so that the gland 50 can be easily assembled and connected to the fixed core 22 while ensuring hard support for the sealing assembly 40.

[0046] like Figure 2 As shown, in one embodiment, the solenoid valve 100 further includes a diaphragm 60 , which is at least partially disposed in the movable iron core 21 and connected to the movable iron core 21 , and the movable iron core 21 can be pressed against the valve port edge of the valve port 11 through the diaphragm 60 to seal the valve port 11 .

[0047] like Figure 2 As shown, in one embodiment, the solenoid valve 100 also includes a gasket 70, which is arranged between the movable iron core 21 and the diaphragm 60. When the movable iron core 21 is pressed against the valve port edge of the valve port 11 through the diaphragm 60 to block the valve port 11, the movable iron core 21 can support the diaphragm 60 through the gasket 70 to prevent the diaphragm 60 from being pressurized and falling into the movable iron core 21 when blocking the valve port 11.

[0048] like Figure 2 As shown, in one embodiment, the solenoid valve 100 also includes a magnetic isolation tube 80 and a winding coil 110. The magnetic isolation tube 80 is fixedly connected to the valve body 10, and the winding coil 110 is mounted on the magnetic isolation tube 80; wherein the fixed iron core 22 is at least partially inserted into the magnetic isolation tube 80 and connected to the magnetic isolation tube 80, and the movable iron core 21 is movably installed in the magnetic isolation tube 80.

[0049] In this embodiment, the solenoid valve 100 further includes an elastic member 90, which is mounted on the movable iron core 21 and respectively contacts the magnetic isolation tube 80 and the movable iron core 21, and is used to drive the movable iron core 21 to elastically reset. In this way, when the solenoid valve 100 is working, once the winding coil 110 is energized, a magnetic field will be generated, and the movable iron core 21 will overcome the elastic force of the elastic member and move toward the fixed iron core 22. At the same time, the movable iron core 21 will drive the diaphragm 60 to release the blockage of the valve port 11 of the valve body 10, and open the flow path controlled by the solenoid valve 100; and when the winding coil 110 is de-energized, the movable iron core 21 will elastically reset under the action of the elastic member, and the valve port 11 will be re-blocked, and the flow path will be cut off.

[0050] In this embodiment, the elastic member 90 may be specifically configured as a spring. Of course, for those skilled in the art, the elastic member 90 may also be configured as other rubber sleeves with higher elasticity, etc., which will not be elaborated here.

[0051] The present application also provides a water dispenser (not shown), comprising the solenoid valve 100 described above.

[0052] In summary, the solenoid valve 100 and water dispenser for which protection is requested in the present application utilize the connecting rod 30 to drive the movable iron core 21 to move toward the fixed iron core 22, so as to release the blocking of the valve port 11 by the movable iron core 21, so that once a power outage occurs during the use of the solenoid valve 100, people can manually pull up the connecting rod 30 to drive the movable iron core 21 to open the valve port 11, so that the flow path controlled by the solenoid valve 100 can be opened to meet emergency needs; at the same time, since the connecting rod 30 and the movable iron core 21 are limited by the first limiting member 31, the connecting rod 30 can pass through the movable iron core 21 and be limited by the first limiting member 31 to realize the assembly between it and the movable iron core 21, so that the coordination between the connecting rod 30 and the movable iron core 21 can be facilitated.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
