The fluid supply unit 10 outputs fluid according to a pulsation signal of a preset pressure and flow rate. The first path is connected between the fluid supply unit 10 and the switching unit 20; the second path P2 is connected between the switching unit 20 and the fluid receiving device 30.

[0028] Specifically, the fluid supply unit 10 in this embodiment can be a pump to supply gas. The pump has an inlet and an outlet, the inlet is connected to a gas or liquid supply source, and the outlet is connected to the first path P1.

[0029] The first path P1 may be a hollow tube, one end of which is connected to the fluid supply unit 10 , and the other end of which is connected to the switching unit 20 .

[0030] The switching unit 20 has a switch form (not limited thereto). The switching unit 20 is connected to the first path P1 and the second path P2 to control the opening or closing between the first path P1 and the second path P2. The switching unit 20 of this embodiment can be a solenoid valve or an electromagnet, which controls the opening or closing of the switching unit 20 by electricity. Alternatively, the switching unit 20 can also be a motor-controlled dispensing valve, which uses motor control to control the opening or closing and flow direction of the fluid. The switching unit 20 can also be a piezoelectric valve, which can provide more precise control.

[0031] The second path P2 may be a hollow tube, one end of which is connected to the switching unit 20 , and the other end of which is connected to the fluid receiving device 30 .

[0032] The fluid receiving device 30 is connected to the other end of the second path P2. The fluid receiving device 30 can receive the fluid output by the fluid supply unit 10 through the switching unit 20. The fluid receiving device 30 can be an air bag, an air bag, etc., a filling device with an expandable or contractible volume.

[0033] Among them, when the gas output by the fluid supply unit 10 is supplied to the first path P1 to pressurize the gas volume of the first path P1, the switching unit 20 is turned on, so that the pressurized gas volume can be instantly released to the fluid receiving device 30 through the second path P2, so that the volume in the fluid receiving device 30 changes instantly to produce a knocking and pressing effect like a massage function.

[0034] Thus, the pulsation control device of the utility model can instantly control the fluid receiving device 30 to produce a cyclic action of expansion and contraction in a very short time, for example, 10 cycles in 1 second, or 50 cycles in 10 seconds, and through instantaneous repeated cyclic expansion and contraction, the pulse massage user can feel the effect of pulse massage.

When the switching unit 20 is turned on, the pressurized fluid volume of the pressure regulating space 40 can be transmitted to the fluid receiving device through the second path P2, so that the volume of the fluid receiving device 30 can expand, providing another pressure regulating function, so as to produce an effect of increasing force during massage.

[0039] [Fourth embodiment]

[0040] like Figure 4 As shown, compared with the first embodiment, the pulsation control device of this embodiment can also include a pressure regulating space 40 to serve as an additional pressurization function. The difference from the second embodiment is that the pressure regulating space 40 is connected to the first path P1, wherein the fluid volume of the pressure regulating space 40 can be transmitted to the switching unit 20 through the first path P1 after being pressurized. When the switching unit 20 is turned on, the pressurized fluid volume of the pressure regulating space 40 can be transmitted to the fluid receiving device 30 through the second path P2, so that the volume of the fluid receiving device 30 can expand, providing another pressure regulating function, so as to produce an effect of increasing force during massage.

Specifically, the switching unit 20 is provided with a second outlet 21, and the second outlet 21 is connected to the atmosphere to release the fluid volume into the atmosphere through the second outlet 21. In this way, the volume of the fluid receiving device 30 can be shrunk to produce an effect similar to loosening the force during massage.

[0045] [Seventh embodiment]

The control circuit 221 controls a plurality of valves 222 with a switch function, and each valve 222 can control at least one fluid receiving device 30, such as an airbag on a vehicle. This can provide a user input / output interface to control the pulsation control device of this embodiment, such as the operating time, pulse massage intensity, etc. of the seat massage device on the vehicle.

Specifically, Figure 8 As shown, the pulsation signal of the preset pressure and flow is a control value generated according to a pulsation curve of a pressure and a corresponding capacity. The pulsation curve can have different preset curves, such as curve A or curve B, which can correspond to the same pressure Pb and have an expected flow Fa or flow Fb, which is transmitted to the fluid supply unit 10, and then provide different fluid volumes to the fluid receiving device, forming instantaneous expansion effects of different sizes, which function like providing different massage effects. Curve A and curve B can have the same expected flow Fc at the same pressure Pc. The pulsation curve can be set in the electronic control unit C, specifically, it can be stored in a memory, and through a human-machine interface, the user can select different pulsation curves corresponding to different massage modes.

[0050] Using the switching unit 20 to close the connection between the first path P1 and the second path P2;

[0051] Turning on the fluid supply unit 10 to supply fluid to the first path P1 to increase the fluid volume of the first path P1; and

[0052] The switching unit 20 is turned on to connect the first path P1 and the second path P2, so that the pressurized fluid volume is instantly released to the fluid receiving device 30 through the second path P2, thereby changing the volume in the fluid receiving device 30.

[0053] In summary, through the pulsation control device of the utility model, when the gas output by the fluid supply unit 10 is supplied to the first path P1 to pressurize the gas volume of the first path P1, the switching unit 20 is turned on, so that the pressurized gas volume can be instantly released to the fluid receiving device 30 through the second path P2, so that the volume in the fluid receiving device 30 changes instantaneously to produce a knocking and pressing effect like a massage function.
