The second sealing ring 3 has the function of preventing water from flowing into the drip coffee pipeline when making capsule coffee and also preventing water from flowing into the capsule coffee pipeline when making drip coffee.
In this embodiment the circumferential wall of the valve stem 2 to the left of the first annular groove 14 is not completely sealed from the circumferential wall of the cavity, so that communication between the first annular groove 14 and the balancing chamber 9 is achieved.
In this embodiment, the right end of the cavity is open, the right end of the cavity is closed by using an end cover 5, and in this embodiment, the right end of the valve rod 2 is contacted with the left side wall of the end cover 5 through a connecting rod. The right side of the end cap 5 in this embodiment is fixed by a snap ring 6. In this embodiment, the right end of the first flow channel 16 is open, and the right end of the first flow channel 16 is closed by using the steel ball 7. In this embodiment, the top end of the second flow channel 17 is open, and the top end of the second flow channel 17 is closed by using a first steel ball. Thereby facilitating the production and installation of the whole product.
In this embodiment, a blind hole is formed at the left end of the valve rod 2, the right end of the spring 1 is connected with the right wall of the blind hole, and the left end of the spring 1 is connected with the left wall of the balance cavity 9. To achieve that the left end of the valve stem 2 is in contact with the left wall of the cavity when making drip coffee, facilitating the arrangement of the whole device, e.g. the valve stem 2 in relation to the second flow channel 17.
The specific working principle is as follows: when the electromagnetic water heater is used, the electromagnetic pump pumps water from the water tank to enter the boiler, the outlet of the boiler is connected with the water inlet hole 11, water enters the power cavity 8 after being heated by the boiler, the flow of the water inlet hole 11 is controlled to realize different flow outputs, so that different coffee types are manufactured, and the control mode can be to regulate and control the flow of the boiler output, the flow of the electromagnetic pump and the like.
The first outlet 12 is connected to the capsule coffee line. The second outlet opening 13 is connected to the drip coffee line.
When the capsule coffee is to be made, the electromagnetic pump is in low flow mode, and when the flow rate of the water flow is low, the low flow rate water can completely pass through the throttle orifice 10, and the first annular groove 14 is completely isolated from the second annular groove 15 because the balance cavity 9 is communicated with the first annular groove 14. The pressure in the power chamber 8 is kept consistent with the pressures in the water inlet 11, the first flow passage 16, the second flow passage 17, the first annular groove 14 and the balance chamber 9 by Bernoulli equation, and is in a low pressure state. According to the stress condition (F bullet+p balance cavity) P power cavity (a, P are equal) of the valve rod 2, both ends of the valve rod 2 are subjected to the same hydraulic force, so that the valve rod 2 keeps the original state, and the valve rod 2 cannot be shifted and switched. When the pressure of the capsule is slow, the pressure of the whole pipeline is established, but the pressures at the two ends of the valve rod 2 are kept consistent, so that the valve rod 2 cannot move, and the making of the capsule coffee is realized.
The water flow path is that the low-flow-rate water enters the power cavity 8 through the water inlet hole 11, then enters the first flow passage 16 through the throttle hole 10, then enters the second flow passage 17, then enters the first annular groove 14, and then enters the capsule coffee pipeline through the first liquid outlet hole 12.
When drip coffee is desired, the electromagnetic pump is in a high flow mode. High flow rate water enters the power chamber 8 through the water inlet hole 11, and the diameter of the water inlet hole 11 is larger than that of the throttle hole 10 due to the throttle hole 10. As can be seen from the bernoulli equation, the volume is fixed, the mass is proportional to the pressure, and because the flow rate of water is high, the orifice 10 cannot discharge all the water rapidly entering the power chamber 8 into the first flow channel 16, which results in the inflow mass in the power chamber 8 being greater than the outflow mass, the pressure in the power chamber 8 rapidly rises, the pressure in the power chamber 8 is greater than the pressures in the first flow channel 16, the second flow channel 17, the first annular groove 14 and the balance chamber 9, at this time, the stress condition of the valve rod 2 (fbullet+p balance chamber < P power chamber a), the valve rod 2 is subjected to a leftward force, the valve rod 2 moves leftward until the left end of the valve rod 2 contacts the left wall of the cavity, at this time, the second annular groove 15 communicates with the second flow channel 17, and the second liquid outlet hole 13 communicates with the second annular groove 15.
The flow of water at this time is: the high-flow-rate water enters the power cavity 8 through the water inlet hole 11, then enters the first flow passage 16 through the throttle hole 10, then enters the second flow passage 17, then enters the second annular groove 15, and then enters the drip coffee pipeline through the second liquid outlet hole 13, so that the drip coffee is manufactured.
When the drip coffee working mode is finished, the electromagnetic pump stops working, and the pressure of the power cavity 8 is reduced, and when the left side of the valve rod 2 is stressed more than the right side, the valve rod 2 is reset and returns to the initial state.
The device does not need to switch pipelines like an electromagnetic valve, only needs to adjust the output of the electromagnetic pump, is convenient to use, does not need expensive manufacture of the electromagnetic valve, has a pure mechanical structure, and is simple to produce and low in price.
It is emphasized here that it is necessary to ensure that the balance chamber 9 communicates with the first annular groove 14, so that the pressure in the balance chamber 9, the first annular groove 14 and the power chamber 8 is uniform and that the valve stem 2 does not move during the slow pressure. If the balance chamber 9 is directly communicated with the outside, after the pressure of the power chamber 8 is increased, the pressure is larger than the pressure of the balance chamber 9, and the valve rod 2 is still caused to move leftwards, so that the making of the capsule coffee cannot be realized. If the balancing chamber 9 is in a completely closed state, when making drip coffee, the pressure will increase rapidly due to the compression of the balancing chamber 9, so that when P balancing chamber a+f bullet=p power chamber a, the valve rod 2 cannot move any more, and because the pressure of the high flow rate water flow in the power chamber 8 is limited, the compression space will bring about a rapid pressure rise, so that the valve rod 2 can move only a little distance to the left, which is insufficient to realize the communication between the second annular groove 15 and the second flow channel 17, and thus the making of drip coffee cannot be realized.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
