Technical Field

[0002] With the improvement of living standards, health has become the most concerned issue for people. Environmental pollution is getting worse, especially water problems. Water purifiers have provided healthy water to many families, reducing the harm of water pollution to health. For most families, water purifiers have become a necessity.

[0003] Currently, water purifiers can produce hot water, cold water and room temperature water. However, medium temperature water (25°C to 40°C) suitable for users to drink cannot be produced by current water purifiers, which reduces the user experience. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect of the prior art that medium-temperature water suitable for users to drink cannot be discharged from current water dispensers, and to provide a solenoid valve and a water purification device containing the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model discloses a solenoid valve, which is applied to a water purification device. The solenoid valve comprises a first channel, a second channel, a connecting channel and a blocking member. The blocking member is arranged in each of the first channel and the second channel, and is used to control the opening and closing of the first channel and the second channel. The outlet of the first channel and the outlet of the second channel are connected through the connecting channel. The outlet of the solenoid valve is arranged on the connecting channel. The inlet of the first channel is used to connect to a normal temperature water source, and the inlet of the second channel is used to connect to a hot water source. A flow limiting member is connected to the inner wall surface of the connecting channel close to the second channel and / or the outlet of the second channel close to the second channel. The projection of the flow limiting member in the axial direction of the connecting channel and / or the second channel covers part of the connecting channel and / or the second channel, so that the flow rate flowing through the flow limiting member is less than the flow rate of the first channel.

[0007] In this solution, when the user wants to use normal temperature water, the blocking member located in the first channel is opened, and the first channel is connected to the outlet of the solenoid valve through the connecting channel. At this time, the normal temperature water flows out from the outlet of the solenoid valve after passing through the first channel and the connecting channel in sequence, so that the user can receive normal temperature water from the outlet of the solenoid valve; when the user wants to use hot water, the blocking member located in the second channel is opened, and the second channel is connected to the outlet of the battery valve through the connecting channel. At this time, the hot water flows out from the outlet of the solenoid valve after passing through the second channel and the connecting channel in sequence, so that the user can receive hot water from the outlet of the solenoid valve; in addition, under the action of the flow limiting member, the flow rate flowing through the flow limiting member is less than the flow rate of the first channel, which reduces the flow rate of the hot water outflow, thereby reducing the probability of the user being scalded; when the user wants to use medium temperature water, the blocking members located in the first channel and the second channel are both opened, and the first channel and the second channel are both connected to the outlet of the solenoid valve through the connecting channel. At this time, the normal temperature water and the hot water will flow out from the outlet of the battery valve after mixing in the connecting channel. With the above structure, normal temperature water and hot water are mixed, and the temperature of the hot water is lowered, so that the temperature of the water flowing out of the outlet of the solenoid valve is suitable for users to drink, which improves the user experience. In addition, under the action of the flow limiting component, the flow rate of hot water is less than the flow rate of normal temperature water, so that after the two are mixed, they can reach medium normal temperature water to meet the needs of users.

[0008] Preferably, the solenoid valve further includes a third channel, a blocking member is provided in the third channel for controlling the on-off of the third channel, the inlet of the third channel is used to connect to a hot water source, and the outlet of the third channel is connected to the first channel and the second channel through the connecting channel;

[0009] The flow rate of the third channel is greater than the flow rate flowing through the flow limiting member.

[0010] In this solution, when the user wants to use hot water, the blocking piece in the third channel is opened, and the third channel is connected to the outlet of the battery valve through the connecting channel. At this time, the hot water flows out from the outlet of the solenoid valve after passing through the third channel and the connecting channel in sequence, so that the user can get hot water from the outlet of the solenoid valve. In addition, the flow rate of the third channel is greater than the flow rate flowing through the flow limiting piece, so that the flow rate of hot water flowing out of the third channel is greater than the flow rate of hot water flowing out of the second channel, and then the water temperature after the normal temperature water flowing out of the first channel and the hot water flowing out of the second channel are mixed is lower than the water temperature after the normal temperature water flowing out of the first channel and the hot water flowing out of the third channel are mixed.

When the second coil is energized, the magnetism of the second coil is opposite to the magnetism of the first end of the second armature, so that the second armature is attracted by the second armature under the magnetism of the second coil, so that the second armature can drive the second blocking part to move in the direction away from the outlet of the second channel, so that the inlet of the second channel and the outlet of the second channel are connected, and the movement efficiency of the second armature is improved.

[0086] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0087] like Figures 1 to 6As shown, this embodiment provides a solenoid valve 1, which is applied to a water purification device 100. The solenoid valve 1 includes a first channel 11, a second channel 12, a connecting channel 13 and a blocking member 14. The first channel 11 and the second channel 12 are both provided with the blocking member 14 for controlling the on-off of the first channel 11 and the second channel 12; the outlet 112 of the first channel and the outlet 122 of the second channel are connected through the connecting channel 13, the outlet 19 of the solenoid valve is provided on the connecting channel 13, the inlet 111 of the first channel is used to connect to a normal temperature water source, and the inlet 121 of the second channel is used to connect to a hot water source; the flow limiting member 15 can have the following embodiments. In the first embodiment, the connecting channel 13 is close to the inner wall of the second channel 12. A flow limiting member 15 is connected to the wall surface, and the projection of the flow limiting member 15 in the axial direction of the connecting channel 13 covers part of the connecting channel 13; in the second embodiment, the flow limiting member 15 is connected to the outlet 122 of the second channel near the second channel, and the projection of the flow limiting member 15 in the axial direction of the second channel 12 covers part of the second channel 12; in the third embodiment, the flow limiting member 15 is connected to the inner wall surface of the connecting channel 13 near the second channel 12 and the outlet 122 of the second channel near the second channel, and the projection of the flow limiting member 15 in the axial direction of the connecting channel 13 covers part of the connecting channel 13 and the projection of the flow limiting member 15 in the axial direction of the second channel 12 covers part of the second channel 12. In this embodiment, the flow limiting member 15 is connected to the inner wall surface of the connecting channel 13 near the second channel 12, and the projection of the flow limiting member 15 in the axial direction of the connecting channel 13 covers part of the connecting channel 13, so that the flow rate flowing through the flow limiting member 15 is less than the flow rate of the first channel 11. Specifically, when the user wants to use normal temperature water, the blocking member 14 located in the first channel 11 is opened, and the first channel 11 is connected to the outlet 19 of the solenoid valve through the connecting channel 13. At this time, the normal temperature water flows out from the outlet 19 of the solenoid valve after passing through the first channel 11 and the connecting channel 13 in sequence, so that the user can receive normal temperature water from the outlet 19 of the solenoid valve; when the user wants to use hot water, the blocking member 14 located in the second channel 12 is opened, and the second channel 12 is connected to the outlet of the battery valve through the connecting channel 13. At this time, the hot water flows out from the outlet 19 of the solenoid valve after passing through the second channel 12 and the connecting channel 13 in sequence. Hot water flows out from the outlet 19 of the solenoid valve, so that the user can get hot water from the outlet 19 of the solenoid valve; in addition, under the action of the flow limiting member 15, the flow rate flowing through the flow limiting member 15 is less than the flow rate of the first channel 11, which reduces the flow rate of the hot water outflow, thereby reducing the probability of the user being scalded; when the user wants to use medium-temperature water, the blocking members 14 located in the first channel 11 and the second channel 12 are opened, and the first channel 11 and the second channel 12 are connected to the outlet 19 of the solenoid valve through the connecting channel 13. At this time, the room temperature water and the hot water will mix in the connecting channel 13 and then flow out from the outlet of the battery valve.With the above structure, normal temperature water and hot water are mixed, and the temperature of the hot water is lowered, so that the temperature of the water flowing out of the outlet 19 of the solenoid valve is suitable for users to drink, thereby improving the user experience. In addition, under the action of the flow limiting member 15, the flow rate of hot water is less than the flow rate of normal temperature water, so that after the two are mixed, they can reach medium normal temperature water, meeting the needs of users.

[0088] It should be specifically explained that the blocking member 14 controlling the on-off of the first channel 11 is used as an example for detailed description. The blocking member 14 can be arranged at the inlet 111 of the first channel, or between the inlet 111 of the first channel and the outlet 112 of the first channel, or at the outlet 112 of the first channel to cut off the connection between the inlet 111 of the first channel and the outlet 112 of the first channel. In order to achieve the connection between the inlet 111 of the first channel and the outlet 112 of the first channel, the blocking member 14 can move above or below the inlet 111 of the first channel and the outlet 112 of the first channel. In addition, for the flow limiting member 15, the outer wall surface of the flow limiting member 15 is completely connected to the inner wall surface of the first channel 11 and the second channel 12, and a through hole is provided on the flow limiting member 15 to achieve flow limiting. In other embodiments, the specific flow limiting form of the flow limiting member 15 may not be limited.

Specifically, when the user wants to use hot water, the blocking member 14 in the third channel 16 is opened, and the third channel 16 is connected to the outlet of the battery valve through the connecting channel 13. At this time, the hot water flows out from the outlet 19 of the solenoid valve after passing through the third channel 16 and the connecting channel 13 in sequence, so that the user can receive hot water from the outlet 19 of the solenoid valve. In addition, the flow rate of the third channel 16 is greater than the flow rate flowing through the flow limiting member 15, so that the flow rate of hot water flowing out of the third channel 16 is greater than the flow rate of hot water flowing out of the second channel 12, and thus the water temperature after the normal temperature water flowing out of the first channel 11 and the hot water flowing out of the second channel 12 are mixed is lower than the water temperature after the normal temperature water flowing out of the first channel 11 and the hot water flowing out of the third channel 16 are mixed. With the above structure, users can choose to open the blocking members 14 in different channels according to actual needs to meet the drinking water needs of different water temperatures, thereby improving the user experience.

[0091] It should be specifically explained that the blocking member 14 located in the third channel 16 can achieve the connection or disconnection of the channel in the same manner as the blocking member 14 located in the first channel 11 or the second channel 12. In other words, the blocking member 14 includes a third driving portion 145 and a third blocking portion 146, the third blocking portion 146 is disposed at the outlet 162 of the third channel, and the third driving portion 145 is connected to the third blocking portion 146 to drive the third blocking portion 146 to move toward or away from the outlet 162 of the third channel, so as to connect or disconnect the inlet 161 of the third channel and the outlet 162 of the third channel.

[0092] In this embodiment, the first driving portion 141 includes a first coil 1411 and a first armature 1412. The first coil 1411 is sleeved on a first end of the first armature 1412. The first coil 1411 and the first end of the first armature 1412 have opposite magnetic properties.

The second end of the first armature 1412 extends out of the first coil 1411 and the first blocking portion 1412. 2 connection; the second driving part 143 includes a second coil 1431 and a second armature 1432, the second coil 1431 is sleeved on the first end of the second armature 1432, the second coil 1431 and the first end of the second armature 1432 have opposite magnetic properties, the inner wall of the second coil 1431 and the first end of the second armature 1432 have a second gap 114 in the moving direction of the second blocking part 144, and the second end of the second armature 1432 extends out of the second coil 1431 and is connected to the second blocking part 144. Specifically, when the first coil 1411 is energized, the magnetism of the first coil 1411 is opposite to the magnetism of the first end of the first armature 1412, so that the first armature 1412 is adsorbed by the first armature 1412 under the magnetic effect of the first coil 1411, so that the first armature 1412 can drive the first blocking portion 142 to move in a direction away from the outlet 112 of the first channel, thereby achieving connection between the inlet 111 of the first channel and the outlet 112 of the first channel, and improving the movement efficiency of the first armature 1412. When the second coil 1431 is energized, the magnetism of the second coil 1431 is opposite to the magnetism of the first end of the second armature 1432, so that the second armature 1432 is adsorbed by the second armature 1432 under the magnetic effect of the second coil 1431, so that the second armature 1432 can drive the second blocking portion 144 to move in a direction away from the outlet 122 of the second channel, thereby achieving connection between the inlet 121 of the second channel and the outlet 122 of the second channel, and improving the movement efficiency of the second armature 1432.

[0093] In other embodiments, the first driving part 141 and the second driving part 143 may also be motors, so that the first blocking part 142 and the second blocking part 144 are driven by the motors to move, so as to realize the on-off switching of the first channel 11 and the second channel 12 .

[0094] like Figures 1 to 3As shown, there are several embodiments for the first driving part 141 and the second driving part 143. In the first embodiment, the first driving part 141 also includes a first elastic component 1413, the first elastic component 1413 is arranged in the first gap 113, and the two ends of the first elastic component 1413 are respectively connected to the inner wall of the first coil 1411 and the first armature 1412; in the second embodiment, the second driving part 143 also includes a second elastic component 1433, the second elastic component 1433 is arranged in the second gap 114, and the two ends of the second elastic component 1433 are respectively connected to the inner wall of the second coil 1431 and the second armature 1432.

Specifically, when the first coil 1411 is powered off, under the action of the first elastic component 1413, the first armature 1412 is restored to the initial position, thereby driving the first blocking part 142 to restore to the initial position through the first armature 1412, and then the outlet 112 of the first channel can be blocked by the first blocking part 142. The above structural form improves the efficiency of the first armature 1412 restoring to the initial position. When the second coil 1431 is powered off, the second armature 1432 is restored to its initial position under the action of the second elastic component 1433, thereby driving the second blocking portion 144 to restore to its initial position through the second armature 1432, and then the outlet 122 of the second channel can be blocked by the second blocking portion 144. The above structure improves the efficiency of the second armature 1432 restoring to its initial position.

[0096] In this embodiment, in the vertical direction of the solenoid valve 1, the inlet 111 of the first channel is lower than the outlet 112 of the first channel, the first driving part 141 is connected to the end of the first blocking part 142 away from the outlet 112 of the first channel, and in the axial direction of the first channel 11, the projection of the first blocking part 142 completely covers the first channel 11; and in the vertical direction of the solenoid valve 1, the inlet 121 of the second channel is lower than the outlet 122 of the second channel, the second driving part 143 is connected to the end of the second blocking part 144 away from the outlet 122 of the second channel, and in the axial direction of the second channel 12, the projection of the second blocking part 144 completely covers the second channel 12.

The second blocking part 144 can prevent water entering the second channel 12 from soaking the second driving part 143, thereby improving the safety of use.

[0097] like Figures 1 to 3 As shown, the first blocking part 142 includes a first body 1421 and a first connecting part 1422. One of the first body 1421 and the first driving part 141 has a first protrusion, and the other has a first groove matched with the first protrusion. The first connecting part 1422 is connected to the first body 1421 and is arranged along the circumference of the first body 1421. The end of the first connecting part 1422 away from the first body 1421 is connected to the inner wall of the first channel 11. The material of the first connecting part 1422 is an elastic material. With the above structure, the first driving part 141 can be protected by the first body 1421 and the first connecting part 1422. In addition, the material of the first connecting part 1422 is an elastic material, so that the first driving part 141 can drive the first body 1421 to move in the direction away from the outlet 112 of the first channel, reducing the interference of the first connecting part 1422 on the movement of the first body 1421, which is conducive to improving the stability of the movement of the first body 1421.

[0098] like Figures 1 to 4As shown, the second blocking portion 144 includes a second body 1441 and a second connecting portion 1442. One of the second body 1441 and the second driving portion 143 is provided with a second protrusion, and the other is provided with a second groove matched with the second protrusion. The second connecting portion 1442 is connected to the second body 1441 and is arranged circumferentially along the second body 1441. The end of the second connecting portion 1442 away from the second body 1441 is connected to the inner wall of the second channel 12. The material of the second connecting portion 1442 is an elastic material. With the above-mentioned structural form, the second driving portion 143 can be protected by the second body 1441 and the second connecting portion 1442. In addition, the material of the second connecting portion 1442 is an elastic material, so that the second driving portion 143 can drive the second body 1441 to move in a direction away from the outlet 122 of the second channel, reducing the interference of the second connecting portion 1442 on the movement of the second body 1441, which is conducive to improving the stability of the movement of the second body 1441.

[0099] like Figure 4 As shown, in this embodiment, the first blocking portion 142 and the second blocking portion 144 both include a pressure ring 18, and the first connecting portion 1422 and the second connecting portion 1442 are both connected to the inner wall surface of the first channel 11 and the second connecting portion 1442 is connected to the inner wall surface of the second channel 12 through the pressure ring 18.

[0100] It should also be specifically explained that the first body 1421 , the first connecting portion 1422 , the second body 1441 and the second connecting portion 1442 are all made of rubber material, thereby improving the sealing effect.

[0101] like Figure 5 and Figure 6 As shown, the solenoid valve 1 further includes a guide rib 17, which is connected to the inner wall of the communication channel 13 near the outlet 19 of the solenoid valve; the extension direction of the guide rib 17 is the same as the extension direction of at least a part of the communication channel 13. With the above structure, the guide rib 17 reduces the impact of the water flow on the communication channel 13, thereby reducing the low-frequency noise caused by the vibration of the pipeline and improving the user experience.

[0102] like Figure 5 and Figure 6As shown, the connecting channel 13 includes a horizontal portion 131 extending in the horizontal direction and a vertical portion 132 extending in the vertical direction. The horizontal portion 131 is connected to the outlet 112 of the first channel, the outlet 122 of the second channel, and the outlet 162 of the third channel, and the vertical portion 132 is connected and connected to the horizontal portion 131. It should be specifically explained that in this embodiment, the guide rib 17 is arranged on the vertical portion 132. In other embodiments, the guide rib 17 can also be arranged on the horizontal portion 131 or both the vertical portion 132 and the horizontal portion 131. The specific arrangement position of the guide rib 17 is not limited here.

[0103] like Figure 7 As shown, this embodiment continues a water purification device 100, which includes a solenoid valve 1. Specifically, when the user wants to use normal temperature water, the blocking member 14 located in the first channel 11 is opened, and the first channel 11 is connected to the outlet 19 of the solenoid valve through the connecting channel 13. At this time, the normal temperature water flows out from the outlet 19 of the solenoid valve after passing through the first channel 11 and the connecting channel 13 in sequence, so that the user can receive normal temperature water from the outlet 19 of the solenoid valve; when the user wants to use hot water, the blocking member 14 located in the second channel 12 is opened, and the second channel 12 is connected to the outlet of the battery valve through the connecting channel 13. At this time, the hot water flows out from the outlet 19 of the solenoid valve after passing through the second channel 12 and the connecting channel 13 in sequence. The outlet 19 of the solenoid valve flows out, so that the user can get hot water from the outlet 19 of the solenoid valve; in addition, under the action of the flow limiting member 15, the flow rate flowing through the flow limiting member 15 is less than the flow rate of the first channel 11, which reduces the flow rate of the hot water outflow, thereby reducing the probability of the user being scalded; when the user wants to use medium-temperature water, the blocking members 14 located in the first channel 11 and the second channel 12 are both opened, and the first channel 11 and the second channel 12 are both connected to the outlet 19 of the solenoid valve through the connecting channel 13. At this time, the normal temperature water and the hot water will flow out from the outlet of the battery valve after mixing in the connecting channel 13. With the above-mentioned structural form, the normal temperature water and the hot water are mixed, and the water temperature of the hot water is reduced, so that the water temperature flowing out from the outlet 19 of the solenoid valve can be suitable for the user to drink, which improves the user's experience. In addition, under the action of the flow limiting member 15, the flow rate of hot water is less than the flow rate of normal temperature water, so that after the two are mixed, they can reach medium normal temperature water to meet the needs of users.

[0104] The water purifier 100 further includes a filter 2, which is at least disposed at the inlet 111 of the first channel and is used to filter the room temperature water source entering the first channel 11. With the above structure, the room temperature water is filtered by the filter 2, which improves the safety of the user.

[0105] See also Figure 7It is understood that the filter element 2 includes a pre-treatment filter element 21, a reverse osmosis membrane filter element 22, a post-filter element 23 and a polypropylene container for water supply 24 which are connected and communicated in sequence. The polypropylene container for water supply 24 is used to accommodate filtered water, and an LED lamp assembly 25 is provided in the polypropylene container for water supply 24 to sterilize the water in the polypropylene container for water supply 24, and an exhaust pipe is provided in the polypropylene container for water supply 24 to exhaust the polypropylene container for water supply 24 so that the polypropylene container for water supply 24 can be used normally.
