Description

Technical Field

[0001] The invention relates to the field of solenoid valves, and in particular to a solenoid valve and a beverage machine. Background Art

[0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] Solenoid valves are basic automation components that control fluid flow through electromagnetics and are actuators. They are generally used to control fluid flow direction, flow rate, speed and other parameters. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed.

[0004] Traditional solenoid valves are mostly one-inlet-one-outlet or one-inlet-two-outlet, so a single solenoid valve cannot meet the needs of complex waterways. For complex waterways with one inlet and multiple outlets, multiple solenoid valves are usually connected in series or in parallel. However, using multiple solenoid valves takes up a lot of space and is costly. Summary of the invention

[0005] Based on this, it is necessary to provide a solenoid valve that can meet the needs of a complex water circuit with one inlet and multiple outlets without the need for multiple solenoid valves to be connected in series or in parallel.

[0016] In one of the embodiments, a second flow blocking member is further included in the second cavity to prevent the fluid flowing into the second cavity from directly impacting the second plug.

[0037] like Figures 1 to 8 As shown, a solenoid valve 100 provided in one embodiment of the present invention includes a main body 110, a first electromagnetic drainage unit and a second electromagnetic drainage unit.

[0038] Specifically, see Figures 3 to 6 The main body 110 has a first cavity 111, a second cavity 112, a first connecting channel 114 connecting the first cavity 111 and the second cavity 112, a second connecting channel 115 connecting the second cavity 112, a water inlet 116 connecting to the first cavity 111, a first water outlet 117 connecting to the first cavity 111, a second water outlet 118 connecting to the second cavity 112, and a third water outlet 119 connecting to the second connecting channel 115.

[0039] The first electromagnetic drainage unit can selectively switch between the first state and the second state to selectively block the first communication channel 114 and the first water outlet 117. When the first electromagnetic drainage unit is in the first state, the first communication channel 114 is blocked, and the first water outlet 117 is connected to the first cavity 111, so the fluid entering the first cavity 111 through the water inlet 116 flows out through the first water outlet 117. Figure 3 When the first electromagnetic drainage unit is in the second state, the first water outlet 117 is blocked, and the first cavity 111 and the second cavity 112 are connected through the first connecting channel 114. Therefore, the fluid entering the first cavity 111 through the water inlet 116 flows from the first connecting channel 114 to the second cavity 112. Figure 7 and Figure 8 .

[0040] The second electromagnetic drainage unit can selectively switch between the third state and the fourth state to selectively block the second communication channel 115 and the second water outlet 118. When the second electromagnetic drainage unit is in the third state, the second communication channel 115 is blocked, and the second water outlet 118 is connected to the second cavity 112, so the fluid flowing into the second cavity 112 flows out from the second water outlet 118. Figure 7When the second electromagnetic drainage unit is in the fourth state, the second water outlet 118 is blocked, and the second cavity 112 and the third water outlet 119 are connected through the second connecting channel 115. Therefore, the fluid flowing into the second cavity 112 flows through the second connecting channel 115 to the third water outlet 119, and then flows out from the third water outlet 119. Figure 8 .

[0041] It can be understood that the first cavity 111 and the second cavity 112 are connected, so when the first connecting channel 114 is not blocked, the fluid entering through the water inlet 116 can flow into the first cavity 111 and the second cavity 112 in sequence. When the first electromagnetic drainage unit is in the first state, the fluid flows out from the first water outlet 117; when the first electromagnetic drainage unit is in the second state and the second electromagnetic drainage unit is in the third state, the fluid flows out from the second water outlet 118; when the first electromagnetic drainage unit is in the second state and the second electromagnetic drainage unit is in the fourth state, the fluid flows out from the third water outlet 119.

[0042] Therefore, the electromagnetic valve 100 can adjust the states of the first electromagnetic drainage unit and the second electromagnetic drainage unit so that the liquid entering from the water inlet 116 flows out from one of the first water outlet 117, the second water outlet 118 and the third water outlet 119, that is, the liquid can flow out from one of at least three water outlets, achieving the effect of one inlet and multiple outlets. Therefore, the requirements of a complex waterway with one inlet and multiple outlets can be met through one electromagnetic valve 100, avoiding the phenomenon of multiple electromagnetic valves 100 being connected in series or in parallel, taking up less space and having low cost.

[0043] Furthermore, in this embodiment, the main body 110 also has a third cavity 113. The third cavity 113 is connected to the second cavity 112 through the second connecting channel 115, and the third water outlet 119 is directly connected to the third cavity 113. Therefore, when the second electromagnetic drainage unit is in the fourth state, the second water outlet 118 is blocked, and the second cavity 112 and the third cavity 113 are connected through the second connecting channel 115. Therefore, the fluid flowing into the second cavity 112 flows to the third cavity 113 through the second connecting channel 115, and then flows out from the third water outlet 119. Figure 8 .

[0044] Of course, it is understandable that in other feasible embodiments, the main body 110 can also have more cavities, electromagnetic drainage units and water outlets, and adopt the same setting method as mentioned above, so that the liquid entering through the water inlet 116 can flow out through one of more water outlets, such as one inlet and four outlets, one inlet and five outlets, etc.

[0045] Depend on Figure 1 and Figure 2It can be seen that in this embodiment, the main body 110 includes an upper valve body 30, a lower valve body 40 fixedly connected to the upper valve body 30, and a support frame 50 provided on a side of the lower valve body 40 away from the upper valve body 30. And the support frame 50 is fixedly connected to the lower valve body 40. Among them, the water inlet 116, the first water outlet 117 and the second water outlet 118 are provided on the upper valve body, and the third water outlet 119 is provided on the lower valve body. And the liquid flowing in from the water inlet 116 can flow out from one of the first water outlet 117, the second water outlet 118 and the third water outlet 119, so that when the upper valve body 30 and the lower valve body 40 are fixedly connected, there is a connection of the flow channel and / or a connection of the cavity. Therefore, when the upper valve body 30 and the lower valve body 40 are fixedly connected, it is necessary to set a sealing structure between the upper valve body 30 and the lower valve body 40 to prevent water from flowing out from the position where the upper valve body and the lower valve body are connected. Specifically, in this embodiment, the sealing structure between the upper valve body 30 and the lower valve body 40 is a sealing ring 60. Of course, the size of the sealing ring 60 at different positions can be set as needed. Similarly, in this embodiment, a sealing ring 60 is also provided between the lower valve body 40 and the support frame 50. Of course, if an opening is provided on the main body to connect the cavity or the communication channel with the outside world, the opening needs to be sealed while the opening needs to be sealed. For example, Figure 2 The seal 70 in.

[0046] It is understandable that in other feasible embodiments, the main body can also be in two halves, or can be decomposed into several components using other decomposition methods, as long as the relationship between the cavity, the flow channel, the water inlet and the water outlet in the present application is satisfied.

[0047] In this embodiment, the first electromagnetic drainage unit includes a first mover 131, a first coil 133 sleeved on the first mover 131, a first plug 135 located in the first cavity 111 and fixedly connected to the first mover 131, and a first reset member 137; the first coil 133 is not energized, and the first mover 131 is reset under the action of the first reset member 137, so that the first water outlet 117 is blocked by the first plug 135, that is, the first electromagnetic drainage unit is in the second state, reference Figure 7 The first coil 133 is energized, and the first mover 131 moves to drive the first plug 135 to move, so that the first connecting channel 114 is blocked by the first plug 135, that is, the first electromagnetic drainage unit is in the first state. Figure 3 .

[0048] Furthermore, in this embodiment, Figure 3, the first electromagnetic drainage unit also includes a first connector 139 movably inserted into the first connecting channel 114. The two ends of the first connector 139 are fixedly connected to the first plug 135 and the first mover 131 respectively. In the direction perpendicular to the extension of the first connecting channel 114, the cross-sectional area of ​​the first connector 139 is smaller than the cross-sectional area of ​​the first connecting channel 114. Therefore, when the first plug 135 does not block the first connecting channel 114, the fluid in the first cavity 111 can flow to the second cavity 112 through the space between the first connector 139 and the side wall of the first connecting channel 114.

[0049] It should be noted that the first coil 133 needs to be isolated from water, so the first coil 133 cannot be directly located in the first cavity 111. In this embodiment, the first coil 133 is located outside the first cavity 111, and correspondingly, the first mover 131 is also located outside the first cavity 111. By passing the first connecting member 139 connecting the first mover 131 and the first plug 135 through the first connecting channel 114, there is no need to set up another channel for the first connecting member 139, so that the structure of the main body 110 is simpler. In addition, in this embodiment, the first connecting member 139 is spaced from the side wall of the first connecting channel 114, and the friction between the first connecting member 139 and the side wall of the first connecting channel 114 can also be avoided, so that the first mover 131 can drive the first plug 135 to move more smoothly.

[0050] In this embodiment, the first mover 131 and the first connecting member 139 are integrally formed. Of course, in other feasible embodiments, the first mover and the first connecting member can also be separately provided, and the first mover and the first connecting member are fixedly connected. Alternatively, the first mover and the first connecting member are connected by other connecting structures, so that the first mover and the first connecting member can be linked.

[0051] In this embodiment, the main body 110 also has a first accommodating space 102, and the first accommodating space 102 is sealed with the first connecting channel 114, that is, the liquid in the first connecting channel 114 will not flow into the first accommodating space 102. The first mover 131 is partially inserted in the first accommodating space 102, and the first coil 133 is arranged in the first accommodating space 102, and the first coil 133 is sleeved on the first mover 131. On the one hand, the first coil 133 can drive the first mover 131 to move when it is energized; on the other hand, it can also prevent the fluid from flowing into the first accommodating space 102 and causing the first coil 133 to short-circuit. It can be understood that the first accommodating space 102 is located on the side of the first connecting channel 114 away from the first cavity 111.

[0052] In this embodiment, the first restoring member 137 is an elastic member disposed in the first accommodation space 102. Specifically, one end of the first restoring member 137 abuts against the main body 110, and the other end abuts against the first mover 131. The first mover 131 moves along the elastic force of the first restoring member 137. Figure 3 The first electromagnetic drainage unit is in the second state. Correspondingly, after the first coil 133 is energized, the first mover 131 overcomes the elastic force of the first reset member 137 under the action of the magnetic force of the magnetic field generated by the first coil 133. Figure 3 The direction of the view shown moves downward until the first plug 135 blocks the first connecting channel 114, so that the first electromagnetic drainage unit is in the first state.

[0053] More specifically, in this embodiment, the first accommodation space 102 is surrounded by the support frame 50. It is understandable that in other feasible embodiments, the first accommodation space can also be provided on the upper valve body or the lower valve body. Of course, in other feasible embodiments, if the structure of the main body is a two-half type, or is decomposed into several components by other decomposition methods, the first accommodation space is provided on one or several components constituting the main body, and the position and activity requirements of the first mover, the first coil and other structures are met.

[0054] In this embodiment, a frame 80 is fixedly disposed in the first accommodation space 102, and the frame 80 is sleeved on the first mover 131, and the first coil 133 is sleeved on the frame 80. On the one hand, the first mover 131 can be more stably inserted in the first accommodation space 102 to avoid the first mover 131 from tilting; on the other hand, the first mover 131 and the first coil 133 can be isolated by the frame 80.

[0055] Specifically, one end of the first restoring member 137 abuts against the frame 80 , and the frame 80 is fixed in the first accommodating space 102 , thereby achieving abutment between the first restoring member 137 and the support frame 50 , that is, achieving abutment between the first restoring member 137 and the support frame 50 .

[0056] In this embodiment, a pressing plate 90 is further provided on the support frame 50 for covering the first accommodation space 102. On the one hand, it facilitates the sealing connection between the support frame 40 and the lower valve body 40, and on the other hand, it can effectively prevent the first coil and other structures in the first accommodation space 102 except the first mover 131 from slipping out of the first accommodation space 102.

[0057] Of course, it is understandable that in another feasible embodiment, the first coil is not energized, the first mover is reset under the action of the first reset member, and the first connecting channel can also be blocked by the first plug, that is, the first electromagnetic drainage unit is in the first state at this time. Correspondingly, the first coil is energized, the first mover moves, to drive the first plug to move, so that the first water outlet is blocked by the first plug, that is, the first electromagnetic drainage unit is in the second state at this time. Of course, compared with the solenoid valve 100, it is necessary to adjust the position of the first reset member at this time to change the direction of the reset force of the first reset member acting on the first mover.

[0058] In addition, it can be understood that, in another feasible embodiment, the first electromagnetic drainage unit is not limited thereto, and it is sufficient that the first electromagnetic drainage unit can be switched between the first state and the second state.

[0059] In this embodiment, the second electromagnetic drainage unit includes a second mover 151, a second coil 153 sleeved on the second mover 151, a second plug 155 located in the second cavity 112 and fixedly connected to the second mover 151, and a second reset member 157; the second coil 153 is not energized, and the second mover 151 is reset under the action of the second reset member 157, so that the second water outlet 118 is blocked by the second plug 155, that is, the second electromagnetic drainage unit is in the fourth state, reference Figure 8 The second coil 153 is energized, and the second mover 151 moves to drive the second plug 155 to move, so that the second connecting channel 115 is blocked by the second plug 155, that is, the second electromagnetic drainage unit is in the third state. Figure 7 .

[0060] In this embodiment, the structure of the second electromagnetic drainage unit is exactly the same as that of the first electromagnetic drainage unit, which will not be described in detail here. Of course, it can be understood that in other feasible embodiments, the structure of the second electromagnetic drainage unit and the first electromagnetic drainage unit can also be different, as long as they can achieve their own diversion functions.

[0061] Of course, in another feasible embodiment, the second coil is not energized, and the second mover is reset under the action of the second reset member, so that the second communication channel can be blocked by the second plug, that is, the second electromagnetic drainage unit is in the third state. Correspondingly, the second coil is energized, and the second mover moves to drive the second plug to move, so that the second water outlet is blocked by the second plug, that is, the second electromagnetic drainage unit is in the fourth state.

[0062] In this embodiment, see Figures 3 to 6The main body 110 also includes an intermediate cavity 101, and the first cavity 111, the intermediate cavity 101 and the second cavity 112 are connected in sequence. The first cavity 111 and the intermediate cavity 101 are connected through the first connecting channel 114. The fluid in the first cavity 111 first flows to the intermediate cavity 101 through the first connecting channel 114, and then flows to the second cavity 112 from the intermediate cavity 101. Due to the setting of the first connecting member 139, the structure of the first connecting channel 114 can only extend in a straight line, or have a small bend or bend, so that the first connecting member 139 can move in the first connecting channel 114. Therefore, if the second cavity 112 is directly connected to the first cavity 111 through the first connecting channel 114, the relative position relationship between the first cavity 111 and the second cavity 112 is limited. In the present application, through the setting of the intermediate cavity 101, the position of the second cavity 112 can be freely selected as needed, so that the second water outlet 118 can be freely set at the required position.

[0063] More specifically, the middle cavity 101 is connected to the second cavity 112 through the middle communication channel. In addition, in this embodiment, the middle cavity 101 is located on the lower valve body 40, and the second cavity 112 is located on the upper valve body 30. Therefore, the middle communication channel includes a first section 102a provided on the lower valve body 40 and a second end 102b provided on the upper valve body 30. The first section 102a is connected to the middle cavity 101, and the second section 102b is connected to the second cavity 112, so that the liquid in the middle cavity 101 can flow into the second cavity 112 through the middle communication channel through the connection between the first section 102a and the second section 102b.

[0064] In this embodiment, the solenoid valve 100 also includes a first flow baffle 10 which is arranged in the first cavity 111 and partially located on the side of the first plug 135 close to the water inlet 116, so as to prevent the fluid flowing from the water inlet 116 to the first cavity 111 from directly impacting the first plug 135, thereby preventing the first plug 135 from being skewed or deformed due to the impact of the fluid, so as to ensure the sealing effect of the first electromagnetic drainage unit in the first state and the second state respectively.

[0065] In this embodiment, the first baffle 10 extends to at least partially surround the first plug 135. Of course, it can be understood that in other feasible embodiments, the first baffle 10 may be located only on one side of the first plug 135 close to the water inlet 116.

[0066] Similarly, in this embodiment, the solenoid valve 100 also includes a second flow baffle 20 arranged in the second cavity 112 to block the fluid flowing into the second cavity 112 from directly impacting the second plug 155, thereby preventing the second plug 155 from being skewed or deformed due to the impact of the fluid, so as to ensure the sealing effect of the second electromagnetic drainage unit in the second state and the third state respectively.

[0067] In this embodiment, the second flow blocking member 20 is also at least partially disposed around the second plug 155. Similarly, in other feasible embodiments, the second flow blocking member 20 is not limited to being disposed around the second plug 155, and can block the fluid flowing into the second cavity 112 from directly impacting the second plug 155.

[0068] like Fig. 9 A beverage machine 200 provided by an embodiment of the present invention includes a solenoid valve 100 .

[0069] The beverage machine 200 can realize the demand for a complex water circuit with one inlet and multiple outlets through one solenoid valve 100, avoiding the phenomenon of multiple solenoid valves being connected in series or in parallel, occupying a small space, thereby meeting the demand for increasingly miniaturized beverage machines 200, reducing the number of solenoid valves, and reducing costs.

[0070] Specifically, in this embodiment, the beverage machine 200 further includes a heat preservation container 210 and a beverage processing container 230. The first water outlet 117 is a water intake outlet, the second water outlet 118 is connected to the heat preservation container 210, and the third water outlet 119 is connected to the beverage processing container 230. Thus, when water is introduced into the water inlet 116 and the first electromagnetic drainage unit is in the first state, water is discharged from the first water outlet 117. When water is introduced into the water inlet 116, the first electromagnetic drainage unit is in the second state, and the second electromagnetic drainage unit is in the third state, water is discharged from the second water outlet 118, and the water flowing out of the second water outlet 118 flows into the heat preservation container 210. When water is introduced into the water inlet 116, the first electromagnetic drainage unit is in the second state, and the second electromagnetic drainage unit is in the fourth state, water is discharged from the third water outlet 119, and the water flowing out of the third water outlet 119 flows into the beverage processing container 230.

[0071] Therefore, if there is a need for direct drinking, the water entering through the water inlet 116 can be controlled to be in the first state so that it flows out through the first water outlet 117; if there is a need to process into beverages such as tea or juice, the water entering through the water inlet 116 can be controlled to be in the second state and the second electromagnetic drainage unit can be controlled to be in the fourth state so that it flows out through the third water outlet 119; if there is no need for direct drinking or processing into beverages such as tea or juice, and only the heated water needs to be stored in a heat preservation manner, the water entering through the water inlet 116 can be controlled to be in the second state and the second electromagnetic drainage unit can be controlled to be in the third state so that it flows out through the second water outlet 118 and flows into the heat preservation container 210 for heat preservation and storage. The beverage machine provided in this embodiment uses the above-mentioned solenoid valve, combined with the beverage processing container, water intake outlet and heat preservation container, so that the beverage machine can provide purified water, beverages and other liquids, and can quickly provide water at a higher temperature, saving the time used by the user to connect hot water or brew beverages.

[0072] Of course, it is understandable that in other feasible embodiments, the correspondence between the heat preservation container, the beverage processing container and the water outlet can be readjusted according to the positions of the heat preservation container and the beverage processing container relative to the solenoid valve.

[0073] In this embodiment, the beverage machine 200 further includes a first water pump 250, a heating mechanism 270, and a water inlet pipe 290 connected to the water inlet 116. The first water pump 250 can pump out the liquid in the heat preservation container 210 and flow through the heating mechanism 270, and the water inlet pipe 290 can transport the liquid after flowing through the heating mechanism 270 to the water inlet 116. It can be understood that the heat preservation container 210 has a heat preservation effect, and the temperature of the liquid placed in the heat preservation container 210 will also decrease as time goes by. Therefore, the liquid pumped out from the heat preservation container 210 flows through the heating mechanism 270 so that the temperature of the liquid reaches a higher temperature. Of course, the beverage machine 200 can also control whether the heating mechanism 270 is running. That is, when the liquid needs to be heated, the heating mechanism 270 is controlled to run; when the liquid does not need to be heated, the heating mechanism 270 is controlled not to run.

[0074] Specifically, in this embodiment, the water inlet pipe 290 is directly connected to the water outlet of the first water pump 250, and a section of the water inlet pipe 290 is covered by the heating mechanism 270, thereby heating the liquid flowing through the section of the water inlet pipe 290. Of course, in other feasible embodiments, the heating mechanism can also be provided with a heating chamber, and the first water pump pumps out the liquid in the heat preservation container and transports it to the heating chamber of the heating mechanism. The liquid heated in the heating chamber is transported to the water inlet through the water inlet pipe.

[0075] Of course, it is understandable that in this embodiment, the beverage machine 200 further includes a water storage container 240 and a second water pump 260. The second water pump 260 can pump the liquid in the water storage container 240 and flow it through the heating mechanism 270, and the water inlet pipe 290 transports the liquid heated by the heating mechanism 270 to the water inlet 116.

[0076] Similarly, in this embodiment, the water inlet pipe 290 is also connected to the water outlet of the second water pump 260 .

[0077] In this embodiment, the first water pump 250 and the second water pump 260 are both diaphragm pumps. It is understandable that in other feasible embodiments, the first water pump and the second water pump are not limited to diaphragm pumps, but may also be reciprocating pumps, plunger pumps or piston pumps.

[0078] Optionally, in another feasible embodiment, the beverage machine may not be provided with a water storage container, but may be provided with a delivery pipe that can be connected to the water source outlet to directly deliver the water source and flow it through the heating mechanism.

[0079] It can be understood that, in other feasible embodiments, the solenoid valve in the beverage machine is not limited to the solenoid valve 100, but can also be any solenoid valve provided by the present invention.

[0080] 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.

[0081] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
