As shown in fig. 1 to 8, an electromagnetic valve 100 according to an embodiment of the present invention includes a main body 110, a first electromagnetic drainage unit, and a second electromagnetic drainage unit.

Specifically, referring to fig. 3 to 6, the main body 110 has a first chamber 111, a second chamber 112, a first communicating channel 114 communicating the first chamber 111 and the second chamber 112, a second communicating channel 115 communicating the second chamber 112, a water inlet 116 communicating with the first chamber 111, a first water outlet 117 communicating with the first chamber 111, a second water outlet 118 communicating with the second chamber 112, and a third water outlet 119 communicating with the second communicating channel 115.

The first electromagnetic drainage unit can be selectively switched between a first state and a 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 communicated with the first cavity 111, so that the fluid entering the first cavity 111 from the water inlet 116 flows out from the first water outlet 117, as shown in fig. 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 communicated through the first communication channel 114, so that the fluid entering the first cavity 111 from the water inlet 116 flows to the second cavity 112 from the first communication channel 114, see fig. 7 and 8.

The second electromagnetic drainage unit can be selectively switched between a third state and a 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 communicated with the second cavity 112, so that the fluid flowing into the second cavity 112 flows out from the second water outlet 118, referring to fig. 7. When the second electromagnetic drainage unit is in the fourth state, the second water outlet 118 is sealed, and the second cavity 112 and the third water outlet 119 are communicated through the second communication channel 115, so that the fluid flowing into the second cavity 112 flows to the third water outlet 119 through the second communication channel 115, and then flows out of the third water outlet 119, referring to fig. 8.

It is understood that the first chamber 111 and the second chamber 112 are communicated, so that the fluid introduced from the water inlet 116 can sequentially flow into the first chamber 111 and the second chamber 112 in case that the first communication passage 114 is not blocked. When the first electromagnetic drainage unit is in the first state, the fluid flows out of 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 of 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.

Therefore, the electromagnetic valve 100 can make the liquid entering from the water inlet 116 flow out from one of the first water outlet 117, the second water outlet 118 and the third water outlet 119 by adjusting the states of the first electromagnetic drainage unit and the second electromagnetic drainage unit, i.e. the liquid can flow out from one of at least three water outlets, thereby achieving the effect of one inlet and multiple outlets. Therefore, the requirement of a complex waterway with one inlet and multiple outlets can be realized by one electromagnetic valve 100, the phenomenon that a plurality of electromagnetic valves 100 are connected in series or in parallel is avoided, the occupied space is small, and the cost is low.

Further, in the present embodiment, the main body 110 further has a third cavity 113. The third chamber 113 is communicated with the second chamber 112 through a second communication passage 115, and the third water outlet 119 is directly communicated with the third chamber 113. Therefore, when the second electromagnetic drainage unit is in the fourth state, the second water outlet 118 is sealed, and the second cavity 112 and the third cavity 113 are communicated through the second communicating channel 115, so that the fluid flowing into the second cavity 112 flows to the third cavity 113 through the second communicating channel 115, and then flows out from the third water outlet 119, referring to fig. 8.

Of course, it is understood that in other possible embodiments, the main body 110 may further have more cavities, electromagnetic drainage units and water outlets, and the same arrangement is adopted, so that the liquid entering from the water inlet 116 can flow out from one of more water outlets, such as one-in-four-out, one-in-five-out, and the like.

As shown in fig. 1 and 2, in the present 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 bracket 50 disposed on a side of the lower valve body 40 away from the upper valve body 30. And the support bracket 50 is fixedly connected with the lower valve body 40. Wherein, the water inlet 116, the first water outlet 117 and the second water outlet 118 are arranged on the upper valve body, and the third water outlet 119 is arranged on the lower valve body. And, the liquid flowing in from the inlet 116 can flow out from one of the first outlet 117, the second outlet 118 and the third outlet 119, so that the upper valve body 30 and the lower valve body 40 have the butt joint of the flow passage and/or the butt joint of the chamber when they are fixedly connected. Therefore, when the upper valve body 30 and the lower valve body 40 are fixedly connected, a sealing structure needs to be arranged between the upper valve body 30 and the lower valve body 40 to prevent water from flowing out from the butt joint position of the upper valve body and the lower valve body. Specifically, in the present 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 seal ring 60 at different positions can be set as desired. Similarly, in this embodiment, a sealing ring 60 is disposed between the lower valve body 40 and the supporting frame 50. Of course, if the main body is provided with an opening for communicating the cavity or the communication channel with the outside, the opening needs to be sealed while the opening needs to be sealed. Such as seal 70 in fig. 2.

It will be appreciated that in other possible embodiments, the main body may be in two halves or be split into several components in other ways, so as to satisfy the relationship among the cavity, the flow channel, the water inlet and the water outlet in the present application.

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 resetting member 137; the first coil 133 is not energized, and the first mover 131 is reset under the action of the first resetting 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, see fig. 7. The first coil 133 is powered on, and the first mover 131 moves to drive the first plug 135 to move, so that the first communication channel 114 is plugged by the first plug 135, that is, the first electromagnetic drainage unit is in the first state, see fig. 3.

Further, in this embodiment, referring to fig. 3, the first electromagnetic drainage unit further includes a first connecting member 139 movably disposed in the first communicating channel 114. Two ends of the first connecting member 139 are respectively and fixedly connected to the first plug 135 and the first mover 131. The first connection member 139 has a sectional area smaller than that of the first communication passage 114 in a direction perpendicular to the direction in which the first communication passage 114 extends. Therefore, when the first plug 135 does not block the first communicating channel 114, the fluid in the first cavity 111 can flow to the second cavity 112 through the space between the first connecting member 139 and the sidewall of the first communicating channel 114.

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. The first connecting member 139 connecting the first movable element 131 and the first plug 135 is inserted into the first communicating channel 114, i.e., it is not necessary to additionally provide a through 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 element 139 is spaced from the side wall of the first communicating channel 114, and friction between the first connecting element 139 and the side wall of the first communicating channel 114 can be avoided, so that the first movable element 131 can more smoothly drive the first plug 135 to move.

In this embodiment, the first mover 131 and the first connector 139 are integrally formed. Of course, in another possible embodiment, the first mover and the first connector may also be separately provided and fixedly connect the first mover and the first connector. Or the first rotor and the first connecting piece are connected through other connecting structures, so that the first rotor and the first connecting piece can be linked.

In this embodiment, the main body 110 further has a first accommodating space 102, and the first accommodating space 102 is spaced from the first communicating channel 114 in a sealing manner, i.e. the liquid in the first communicating channel 114 does not flow into the first accommodating space 102. The first mover 131 is partially inserted into the first receiving space 102, the first coil 133 is disposed in the first receiving space 102, and the first coil 133 is sleeved on the first mover 131. On the one hand, the first coil 133 is electrified to drive the first mover 131 to move; on the other hand, the fluid can be prevented from flowing to the first accommodating space 102 to cause the short circuit of the first coil 133. It can be understood that the first accommodating space 102 is located on a side of the first communicating channel 114 away from the first cavity 111.

In this embodiment, the first restoring member 137 is an elastic member disposed in the first accommodating space 102. Specifically, the first restoring member 137 has one end abutting the main body 110 and the other end abutting the first mover 131. The first mover 131 moves upward along the view direction shown in fig. 3 under the elastic force of the first restoring member 137 until the first plug 135 plugs the first water outlet 117, so that the first electromagnetic drainage unit is in the second state. Correspondingly, after the first coil 133 is powered on, the first mover 131 overcomes the elastic force of the first resetting member 137 and moves downward along the direction of the view shown in fig. 3 under the magnetic force of the magnetic field generated by the first coil 133, and the first plug 135 plugs the first communication channel 114, so that the first electromagnetic drainage unit is in the first state.

More specifically, in the present embodiment, the first accommodating space 102 is enclosed by the supporting frame 50. It is understood that, in another possible embodiment, the first accommodating space may be provided on the upper valve body or the lower valve body. Of course, in another feasible embodiment, if the structure of the main body is two-half or is decomposed into a plurality of elements by other decomposition methods, the first accommodating space is disposed on one or more of the elements constituting the main body, and the requirements of the positions and activities of the structures such as the first mover and the first coil are satisfied.

In this embodiment, the first accommodating space 102 is further fixedly provided with a frame 80, the frame 80 is sleeved on the first rotor 131, and the first coil 133 is sleeved on the frame 80. On one hand, the first mover 131 can be more stably inserted into the first accommodating space 102, so as to avoid the inclination of the first mover 131; on the other hand, the first mover 131 and the first coil 133 can be isolated from each other by the frame 80.

Specifically, first piece 137 one end that resets and skeleton 80 butt, skeleton 80 are fixed locate in first accommodation space 102 to realize first piece 137 that resets and the butt of support frame 50, realize first piece 137 that resets and the butt of support frame 50 promptly.

In this embodiment, the supporting frame 50 is further provided with a pressing plate 90 for sealing the first accommodating space 102. On one hand, the support frame 40 and the lower valve body 40 are conveniently in sealed butt joint, and on the other hand, the first coil and other structures in the first accommodating space 102 except the first mover 131 can be effectively prevented from sliding out of the first accommodating space 102.

Of course, it can be understood that, in another possible embodiment, the first coil is not powered on, the first mover is reset under the action of the first resetting member, and the first communication 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 electrified, the first rotor moves to drive the first plug to move, so that the first water outlet is plugged by the first plug, and at the moment, the first electromagnetic drainage unit is in the second state. Of course, in comparison to the electromagnetic valve 100, the position of the first resetting member needs to be adjusted at this time to change the direction of the resetting force of the first resetting member acting on the first mover.

In addition, it is understood that, in another possible 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.

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; when the second coil 153 is not energized, the second mover 151 is reset under the action of the second resetting member 157, so that the second water outlet 118 is plugged by the second plug 155, that is, the second electromagnetic drainage unit is in the fourth state, referring to fig. 8. When the second coil 153 is energized, the second mover 151 moves to drive the second plug 155 to move, so that the second communicating channel 115 is plugged by the second plug 155, that is, the second electromagnetic drainage unit is in the third state, see fig. 7.

In this embodiment, the second electromagnetic drainage unit and the first electromagnetic drainage unit have the same structure, and are not described herein again. Of course, it is understood that in another possible embodiment, the structures of the second electromagnetic drainage unit and the first electromagnetic drainage unit may be different, and respective flow guiding functions may be achieved.

Of course, in another possible embodiment, the second coil is not energized, the second mover is reset under the action of the second reset piece, and the second communication channel can be plugged by the second plug, that is, the second electromagnetic drainage unit is in the third state. Correspondingly, the second coil is electrified, and the second rotor moves to drive the second plug to move, so that the second water outlet is plugged by the second plug, namely the second electromagnetic drainage unit is in the fourth state.

In this embodiment, referring to fig. 3 to 6, the main body 110 further includes an intermediate cavity 101, and the first cavity 111, the intermediate cavity 101 and the second cavity 112 are sequentially communicated. The first chamber 111 and the intermediate chamber 101 communicate through a first communication passage 114. The fluid in the first chamber 111 first flows to the intermediate chamber 101 through the first communicating channel 114, and then flows from the intermediate chamber 101 to the second chamber 112. Due to the arrangement of the first connecting member 139, the structure of the first communicating channel 114 can only extend along a straight line, or have a small bending or bending amplitude, so that the first connecting member 139 can move in the first communicating channel 114. Therefore, if the second chamber 112 is directly connected to the first chamber 111 through the first communicating passage 114, the relative positional relationship between the first chamber 111 and the second chamber 112 is limited. In the present application, the position of the second cavity 112 can be freely selected according to the requirement by the arrangement of the middle cavity 101, so that the second water outlet 118 can be freely arranged at the required position.

More specifically, the intermediate chamber 101 communicates with the second chamber 112 through an intermediate communication passage. In addition, since the intermediate chamber 101 is located on the lower valve body 40, and the second chamber 112 is located on the upper valve body 30 in the present embodiment. The intermediate communication passage 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 segment 102a is connected with the middle cavity 101 in an abutting mode, and the second segment 102b is connected with the second cavity 112 in an abutting mode, so that liquid in the middle cavity 101 can flow into the second cavity 112 through the middle communication channel due to the fact that the first segment 102a is connected with the second segment 102b in an abutting mode.

In this embodiment, the electromagnetic valve 100 further includes a first flow blocking member 10 disposed in the first cavity 111 and partially located on a 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 inclined or deformed due to the impact of the fluid, and ensuring the blocking effect of the first electromagnetic flow guiding unit in the first state and the second state respectively.

In this embodiment, the first baffle 10 extends at least partially around the first plug 135. Of course, it will be appreciated that in other possible embodiments, the first baffle 10 may be located only on the side of the first plug 135 adjacent the water inlet 116.

Similarly, in this embodiment, the electromagnetic valve 100 further includes a second flow blocking member 20 disposed in the second cavity 112 to block the fluid flowing into the second cavity 112 from directly impacting the second plug 155, so as to prevent the second plug 155 from being inclined or deformed due to the impact of the fluid, and ensure the blocking effect of the second electromagnetic drainage unit in the second state and the third state, respectively.

It is understood that the temperature of the liquid placed in the thermal container 210 is decreased with time because the thermal container 210 has a thermal effect. The liquid pumped out of the thermal container 210 flows through the heating mechanism 270 so that the temperature of the liquid reaches a higher temperature. Of course, the beverage maker 200 may also control whether the heating mechanism 270 operates. That is, when the liquid needs to be heated, the heating mechanism 270 is controlled to operate; when the liquid is not needed for heating, the heating mechanism 270 is controlled not to operate.

Specifically, in this embodiment, the inlet pipe 290 is directly connected to the outlet of the first water pump 250, and a section of the inlet pipe 290 is covered by the heating mechanism 270, so as to heat the liquid flowing through the section of the inlet pipe 290. Of course, in another possible embodiment, the heating mechanism may be provided with a heating cavity, and the first water pump pumps out the liquid in the heat preservation container and conveys the liquid into the heating cavity of the heating mechanism. The liquid heated by the heating cavity is conveyed to the water inlet through the water inlet pipe.

Of course, it is understood that in the present embodiment, the beverage machine 200 further includes a water storage container 240 and a second water pump 260. The second water pump 260 may pump the liquid in the reservoir 240 through the heating mechanism 270, and the inlet pipe 290 may deliver the liquid heated by the heating mechanism 270 to the inlet 116.
