The solenoid valve 100 of the water dispenser 1000 according to an embodiment of the present invention will be described with reference to fig. 1 to 5. It should be noted that the water dispenser 1000 has the water tank 200 for storing water, and in the process of using the water dispenser 1000 for a long time, the water tank 200 may have a problem of scale residue, and in order to ensure the quality and health of the drinking water, the water tank 200 needs to be cleaned periodically. By providing the solenoid valve 100 of the water dispenser 1000, it is possible to control the washing water for cleaning the water tank 200 to be discharged to the external water storage tray 300.

As shown in fig. 1 to 5, a solenoid valve 100 of a water dispenser 1000 according to an embodiment of the present invention is provided. Including a valve seat 110 and a valve element 120.

Specifically, as shown in fig. 1, the valve seat 110 has a mounting cavity 111 therein, and the valve seat 110 has an overflow passage 112, a water inlet passage 113, and a drain passage 114. The water inlet channel 113 may be in communication with the installation cavity 111, the water discharge channel 114 may be in selective communication with the installation cavity 111, the overflow channel 112 may be in constant communication with the water discharge channel 114, and both the water inlet channel 113 and the overflow channel 112 may be in communication with the water tank 200 of the water dispenser 1000, and the water discharge channel 114 may be in communication with the external water storage tray 300.

It should be noted that the water dispenser 1000 may be provided with a control device, the control device may be in communication connection with the electromagnetic valve 100, when the water tank 200 is cleaned, the control device may send an instruction to the electromagnetic valve 100, and the electromagnetic valve 100 may control the water inlet channel 113 to communicate with the water outlet channel 114, so as to remove the cleaning water in the water tank 200. In addition, in consideration of the fact that the solenoid valve 100 is powered off or the water inlet channel 113 is damaged in the practical application process, the cleaning water in the water tank 200 cannot be discharged to the outside through the communication between the water inlet pipeline and the water outlet pipeline. Therefore, the overflow cavity 220 may be formed in the water tank 200, the overflow hole may be formed at the upper end of the overflow cavity 220, and the overflow hole may be formed at the lower end of the overflow cavity 220. When the water level in the water tank 200 exceeds the height of the overflow through which the washing water in the water tank 200 flows to the overflow chamber 220, the overflow passage 112 may communicate with the overflow to discharge the water in the overflow chamber 220 to the outside, preventing the water tank 200 from overflowing.

It should be noted that, in the normal use process of the water dispenser 1000, there may also be a problem that the control device is damaged, so that the water in the water tank 200 cannot flow out normally, and the water level line is too high, and at this time, the overflow channel 112 may also discharge the water in the overflow cavity 220 outwards, so as to prevent the water tank 200 from overflowing.

As shown in fig. 1, a valve spool 120 is movably provided in the installation cavity 111 to control communication or disconnection of the drain passage 114 and the installation cavity 111. It should be noted that, after the water tank 200 is cleaned, the control device may send a command to the electromagnetic valve 100, the electromagnetic valve 100 controls the valve core 120 to move, so that the drainage channel 114 is communicated with the installation cavity 111, and at this time, the water inlet channel 113 is communicated with the drainage channel 114 through the installation cavity 111, so that the water in the water tank 200 may be drained to the external water storage tray 300 through the communication between the water inlet channel 113 and the drainage channel 114.

After the cleaning water in the water tank 200 is drained, the electromagnetic valve 100 may control the valve core 120 to fall back, so as to disconnect the communication between the drain channel 114 and the installation cavity 111, at this time, the communication between the water inlet channel 113 and the drain channel 114 is disconnected, and the electromagnetic valve 100 enters a state to be triggered.

For example, as shown in fig. 1 and 2, the valve seat 110 may define a mounting cavity 111, a lower end portion of the valve seat 110 is provided with an overflow passage 112, a water inlet passage 113, and a drain passage 114, and as shown in fig. 1 and 2, a front end of the overflow passage 112 communicates with the water tank 200, a rear end of the overflow passage 112 penetrates the mounting cavity 111, and a rear end of the overflow passage 112 communicates with a left end of the drain passage 114, and a left end of the drain passage 114 may communicate with the mounting cavity 111. The left end of inhalant canal 113 communicates with water tank 200, and installation cavity 111 is worn to locate by the right-hand member of inhalant canal 113, and the right-hand member of inhalant canal 113 can communicate with installation cavity 111.

As shown in fig. 1, a valve core 120 is disposed above the drain passage 114, and the valve core 120 may be fitted to a left end of the drain passage 114 to open or close the communication between the drain passage 114 and the installation cavity 111.

According to the utility model discloses solenoid valve 100 of water dispenser 1000, through setting up overflow channel 112 and drainage channel 114 and often communicate, intake passage 113 and drainage channel 114 are optionally communicated, both can make the washing water in the water tank 200 in time discharge, reduce the probability that the overflow appears in water tank 200 to improve water dispenser 1000's reliability, can optimize water dispenser 1000's drainage line's overall arrangement again, save the cost.

As shown in fig. 1, according to some embodiments of the present invention, the drainage channel 114 may include a first drainage section 1141 and a second drainage section 1142. The first water discharge section 1141 may be disposed at the bottom of the valve seat 110, and one end of the first water discharge section 1141 is communicated with the outside to discharge water in the water discharge passage 114 to the outside. One end of the second drainage section 1142 is communicated with the other end of the first drainage section 1141, and the other end of the second drainage section 1142 is higher than the other end of the first drainage section 1141, and the valve core 120 is suitable for opening or closing the other end of the second drainage section 1142 to control the communication or disconnection of the second drainage section 1142 and the installation cavity 111.

It can be understood that the communication end of the second drainage section 1142 with the cavity is higher than the connection end of the second drainage section 1142 with the first drainage section 1141, so that when the water tank 200 drains through the drainage channel 114, the height difference of the two ends of the second drainage section 1142 facilitates the flow of water in the drainage channel 114, thereby improving the reliability of the drainage channel 114.

Further, the other end of the second drain section 1142 may be opened upward, and the valve core 120 may be moved in an up and down direction to open or close the other end of the second drain section 1142. Therefore, when the solenoid valve 100 controls the valve core 120 to disconnect the second drainage section 1142 from the installation cavity 111, the gravity of the valve core 120 may act on the valve core 120 to move downwards to shield the opening of the second drainage section 1142, thereby saving energy.

For example, as shown in fig. 1, the right end of the first drainage section 1141 is communicated with the outside, and the left end of the first drainage section 1141 is inserted into the installation cavity 111. The second drainage section 1142 is disposed in the mounting cavity 111, the second drainage section 1142 is disposed in an up-down direction, a lower end of the second drainage section 1142 is communicated with a left end of the first drainage section 1141, an upper end of the second drainage section 1142 has an open opening opened upward, and the valve core 120 is disposed above the open opening.

As shown in fig. 1, according to some embodiments of the present invention, the valve seat 110 may have a sliding groove for the movement of the valve element 120. Therefore, the sliding groove is arranged, so that the movement of the valve core 120 can be limited, the probability that the upper end of the second drainage section 1142 cannot be closed due to the deviation of the movement track of the valve core 120 in the long-term use of the electromagnetic valve 100 is reduced, and the reliability of the electromagnetic valve 100 is improved.

As shown in fig. 1, the valve spool 120 may include a body 121, a sealing member 122, and an elastic member 123. The body 121 is slidably disposed in the sliding groove, the sealing member 122 is disposed at an end of the body 121, the elastic member 123 is disposed in the sliding groove, and the elastic member 123 and the body 121 can abut against each other to normally push the body 121 to move toward the drainage channel 114; and the sealing member 122 may seal the drain passage 114 to close the drain passage 114 when the drain passage 114 is disconnected from the mounting cavity 111.

It can be understood that when the solenoid valve 100 controls the drain passage 114 to communicate with the mounting cavity 111, the solenoid valve 100 controls the body 121 to move upward along the sliding groove to separate the sealing member 122 from the drain passage 114, and in the process, the body 121 compresses the elastic member 123 to generate elastic stress. When the solenoid valve 100 controls the drain passage 114 to be disconnected from the mounting chamber 111, the solenoid valve 100 may control the body 121 to move downward along the sliding groove to contact the sealing member 122 with the drain passage 114 and seal the drain passage 114, during which the elastic stress of the elastic member 123 may be converted into a power to push the body 121 to move downward. Therefore, the elastic piece 123 abutting against the body 121 is arranged in the sliding groove, so that energy and cost can be saved.

For example, as shown in fig. 1, the valve seat 110 may define a sliding groove extending in the up-down direction, the body 121 may be provided in the sliding groove, and the body 121 may move in the up-down direction along the sliding groove, a sealing member 122 may be provided below the body 121, and an upper end surface of the sealing member 122 may be connected to a lower end surface of the body 121. An elastic member 123 is disposed above the body 121, a lower end of the elastic member 123 contacts an upper end surface of the body 121, and an upper end of the elastic member 123 contacts the valve seat 110.

As shown in fig. 1, according to some embodiments of the present invention, the end of the body 121 may have a flange 1211, and the sealing member 122 may have a groove 1221 adapted to the flange 1211. Therefore, when the sealing member 122 is mounted on the end portion of the body 121, the flange 1211 can be engaged with the groove 1221, so that the sealing member 122 can be easily aligned with the mounting position, and the assembling efficiency of the sealing member 122 can be improved. And through the matching connection of the flange 1211 and the groove 1221, the connection between the sealing element 122 and the body 121 can be limited in the horizontal direction, so that the probability of deviation of the sealing element 122 can be reduced, and the stability and reliability of the connection between the sealing element 122 and the body 121 are improved.

As shown in fig. 1, according to some embodiments of the present invention, the solenoid valve 100 of the water dispenser 1000 may further include a first water jacket 115, and the first water jacket 115 may be attached to an inner wall of the sliding groove. It should be noted that the water in the water tank 200 may flow into the mounting cavity 111 through the water inlet channel 113, and the water in the mounting cavity 111 may flow into the sliding groove along with the movement of the valve core 120, so that the first water jacket 115 is disposed on the inner wall of the sliding groove to prevent the water in the mounting cavity 111 from leaking to other components through the sliding groove, which may cause damage to some components of the solenoid valve 100, thereby improving the reliability of the solenoid valve 100.

Further, the electromagnetic valve 100 of the water dispenser 1000 may further include a second water jacket 116, one end of the second water jacket 116 may be connected to the first water jacket 115, and the second water jacket 116 may be attached to an inner wall surface of the mounting cavity 111. The waterproof structure formed by connecting the second water jacket 116 and the first water jacket 115 can cover the inner wall of the mounting cavity 111, so that the waterproof performance of the inner wall of the mounting cavity 111 can be further improved, and the probability of water leakage in the mounting cavity 111 can be reduced.

As shown in fig. 1, according to some embodiments of the present invention, the inner wall surface of the mounting cavity 111 may have an embedded groove 117, and the other end of the second water jacket 116 may be disposed in the embedded groove 117. Therefore, by forming the embedded groove 117 in the inner wall surface of the mounting cavity 111, which can be matched with the end of the second water jacket 116, the second water jacket 116 can be conveniently aligned with the mounting position, and the assembly efficiency of the second water jacket 116 can be improved. And the second water jacket 116 can be limited by the engagement of the embedded groove 117 with the end of the second water jacket 116, so that the probability of the second water jacket 116 shifting can be reduced, and the reliability of the solenoid valve 100 can be improved.

For example, as shown in fig. 1, the first water jacket 115 is attached to an inner wall of the sliding groove, the second water jacket 116 is located below the first water jacket 115, and an upper end of the second water jacket 116 may be connected to a lower end of the first water jacket 115. An embedded groove 117 is configured on the inner wall surface of the mounting cavity 111 at a position corresponding to the lower end of the second water jacket 116, and the lower end portion of the second water jacket 116 can be inserted into the embedded groove 117.

As shown in fig. 1, according to some embodiments of the present invention, a sealing ring 130 may be disposed in the insertion groove 117, and the sealing ring 130 may be interposed between the other end of the second water jacket 116 and the inner bottom wall of the insertion groove 117. Thus, by providing the seal ring 130 in the fitting groove 117, the sealing property in which the end portion of the second water jacket 116 is fitted into the fitting groove 117 can be improved, and the probability of water in the mounting cavity 111 leaking to the outside through the fitting groove 117 can be reduced.

In some embodiments, the first water jacket 115 and the second water jacket 116 may be an integrally formed piece. Therefore, the cost waste caused by the independent development of the first water jacket 115 or the second water jacket 116 can be avoided, the tightness of the connection between the first water jacket 115 and the second water jacket 116 can be improved, and the water in the mounting cavity 111 can be prevented from leaking from the connection position of the first water jacket 115 and the second water jacket 116.

As shown in fig. 1, according to some embodiments of the present invention, the water inlet channel 113 may be disposed at the bottom of the valve seat 110, and the water inlet channel 113 may communicate with the bottom of the installation cavity 111. It should be noted that, in this embodiment, the electromagnetic valve 100 and the water tank 200 may be mounted on the same mounting platform, and the water inlet channel 113 is disposed at the bottom of the valve seat 110, so that the communication position between the water inlet channel 113 and the water tank 200 may be also located at the bottom of the water tank 200, thereby optimizing the layout and facilitating the clean discharge of the cleaning water in the water tank 200.

As shown in fig. 1 and 4, according to some embodiments of the present invention, the valve seat 110 may have a water inlet connection pipe 118 and an overflow connection pipe 119, the water inlet passage 113 may penetrate the water inlet connection pipe 118, the overflow passage may penetrate the overflow connection pipe 119, the water inlet connection pipe 118 may be communicated with the water tank 200 of the water dispenser 1000, and the overflow connection pipe 119 may be communicated with the overflow port of the water tank 200.

It can be understood that when the inlet connection pipe 118 is connected to the water tank 200, the inlet channel 113 can be connected to the water tank 200, and the water in the water tank 200 can flow into the installation cavity 111 through the inlet channel 113. The overflow passage 112 may communicate with the overflow of the water tank 200 when the overflow connection pipe 119 is connected with the overflow, and at this time, when the water in the water tank 200 reaches the overflow water level, it may flow to the overflow passage 112 through the overflow chamber 220, and the overflow passage 112 may discharge the water to the external water storage tray 300 through the drain passage 114. Thus, the water inlet connection pipe 118 may serve as a connection structure of the water inlet passage 113 to communicate with the water tank 200, and the overflow connection pipe 119 may serve as a connection structure of the overflow passage 112 to communicate with the overflow.

Further, as shown in fig. 3 and 4, the water inlet connection pipe 118 and the overflow connection pipe 119 may be located on the same side of the valve seat 110, and it should be noted that "on the same side" herein may be understood that, when the water inlet connection pipe 118 and the overflow connection pipe 119 are located on the same side of the valve seat 110, the extending direction of the water inlet connection pipe 118 towards the water tank 200 is the same as the extending direction of the overflow connection pipe 119 towards the water tank 200, that is, as shown in fig. 4, when the water inlet connection pipe 118 is connected to the water tank 200, the overflow connection pipe 119 may also be connected to the water tank 200.

In addition, in order to improve the stability of the connection between the water inlet connection pipe 118 and the overflow connection pipe 119 and the water tank 200, in this embodiment, a first connection column 230 and a second connection column 240 may be disposed on the water tank 200, wherein the first connection column 230 may be inserted into the water inlet connection pipe 118, the first connection column 230 has a first through hole communicating the inside of the water tank 200, and the water inlet channel 113 may be communicated with the first through hole. The second connecting column 240 may be inserted into the overflow connecting pipe 119, the second connecting column 240 may form a second through hole communicating with the overflow, and the overflow passage 112 may communicate with the second through hole.

Therefore, when the water inlet connecting pipe 118 and the water overflow connecting pipe 119 are located on the same side of the valve seat 110, correspondingly, the first connecting column 230 and the second connecting column 240 can also be arranged on one side of the water tank 200 facing the electromagnetic valve 100, at this time, the water inlet connecting pipe 118 can be directly plugged with the first connecting column 230, the water overflow connecting pipe 119 can also be directly plugged with the second connecting column 240, and then the layout of the pipeline connection of the electromagnetic valve 100 and the water tank 200 can be optimized, and the cost is saved.

For example, when more parts are disposed on one side of the water inlet connection pipe 118, the overflow connection pipe 119 may be disposed on the other side of the valve seat 110, and the overflow connection pipe 119 may be communicated with the overflow through a hose.

In addition, in some embodiments, a waterproof ring may be disposed at the connection end of the water inlet connection pipe 118 and the first connection column 230, so that the waterproof property of the connection of the water inlet connection pipe 118 and the first connection column 230 may be improved.
