Description

Technical Field

[0001] The present invention relates to a pulsating pressure control device, and more particularly to a device for regulating a corresponding receiving device, such as one or more air bags or airbag inflation devices, through a fluid control method. Background Art

[0002] Conventional massage devices typically use motors to drive rollers to apply varying pressures. These devices require complex motors, gears, and rollers with varying shapes. However, rigid rollers are not capable of providing a soft, pressing effect.

[0003] In addition, the air bags of existing devices that utilize pressure frequency adjustment, such as car seats, sitting massage chairs, and medical beds, can only be slowly adjusted to a fixed state and cannot provide a massage function.

[0004] Therefore, how to improve the software and hardware design structure, integrate fluid to provide the effect of fluctuating pulsation frequency, enhance the effect of pulsation massage, and then apply it to various massage product devices has become an important issue to be solved in this technical field. Utility Model Content

[0005] The technical problem addressed by this invention is to address the shortcomings of the existing technology by providing a cyclical pulsating pressure control device that utilizes fluid to instantaneously increase the volume of a fluid receiving device, thereby providing a pulsating effect with varying fluctuations. To address the aforementioned technical problem, one of the technical solutions employed by this invention is to provide a cyclical pulsating pressure control device comprising a supply unit, a switching unit, a first path, a second path, a fluid receiving device, and a return path. The supply unit outputs a pulsating control signal based on a default pressure and flow rate. The switching unit is a switch located between the first path and the second path. The first path connects between the supply unit and the switching unit. The second path connects between the switching unit and the fluid receiving device, where the fluid receiving device receives fluid output from the supply unit through the switching unit. The return path connects to another path between the switching unit and the supply unit. When the switching unit closes the connection between the first and second paths, the supply unit opens to supply fluid to the first path, thereby increasing the fluid pressure in the first path. When the switching unit is activated to connect the first and second paths, the pressurized fluid volume is instantly released through the second path to the fluid receiving device, causing the volume within the fluid receiving device to change. When the fluid receiving device is depressurized, the switching unit connects the second path to the return path, transferring the fluid to the supply unit through the second and return paths.

[0006] One of the beneficial effects of this invention is that, through the cyclical pulsating pressure control device of this invention, when the gas output by the fluid supply unit is supplied to the first path to increase the gas volume of the first path, the switching unit is turned on, allowing the pressurized gas volume to be instantly released to the fluid receiving device through the second path, thereby causing a momentary change in the volume within the fluid receiving device, thereby producing a tapping and pressing effect similar to a massage function. When the fluid receiving device is depressurized, the switching unit opens the connection between the second path and the return path, transferring the fluid through the return path to the original supply unit, thereby repeating the cycle of fluid pressurization and depressurization.

[0028] First embodiment

[0029] like Figure 1 As shown, the present invention provides a cyclic pulsation pressure control device, which includes a supply unit 10, a switching unit 20, a first path P1, a second path P2, a fluid receiving device 30, and a return path P3. The supply unit 10 provides a pulsation control signal output based on a default pressure and flow rate. The switching unit 20 is a switch located between the first path P1 and the second path P2. The first path P1 is connected between the 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; and the return path P3 is connected to another path between the switching unit 20 and the supply unit 10.

[0030] Specifically, the supply unit 10 in this embodiment can be a pump, primarily used to supply fluid. The pump has an outlet 101 and an inlet 102. The inlet 102 is connected to a gas or liquid supply source, such as atmospheric pressure or a fluid container (not shown), while the outlet 101 is connected to the first path P1.

[0031] The first path P1, the second path P2 and the return path P3 are a kind of pipeline communication device, such as a hollow tube body. The first path P1 of the hollow tube body is connected between the supply unit 10 and the switching unit 20, the second path P2 of the hollow tube body is connected between the switching unit 20 and the fluid receiving device 30, and the return path P3 of the hollow tube body is connected to another return path P3 between the switching unit 20 and the supply unit 10. The first path P1 and the return path P3 are different pipeline communication paths.

[0032] Specifically, the return path P3 of the hollow tube can be divided into a first return path P31 and a second return path P32. The first return path P31 runs from the fluid receiving device 30 to the switching unit 20, and the second return path P32 runs from the switching unit 20 to the supply unit 10. During pressure increase, the fluid volume passing through the first path P1 is pressurized and then instantly released to the fluid receiving device 30 through the second path P2. During pressure reduction, the fluid receiving device 30 transfers the fluid from the fluid receiving device 30 to the switching unit 20 via the first return path P31 and the second return path P32, and then returns the fluid to the supply unit 10.

[0033] The switching unit 20 has a switch form (but not limited to this). The switching unit 20 is connected between the first path P1 and the second path P2, thereby controlling the opening or closing between the first path P1 and the second path P2. The switching unit 20 is connected between the second path P2 and the return path P3, thereby controlling the opening or closing between the second path P2 and the return path P3. 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 through 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 micro-control.

[0034] The fluid receiving device 30 is connected to one end of the second path P2. The fluid receiving device 30 receives the fluid output by the supply unit 10 through the switching unit 20. The fluid receiving device 30 can be an expandable or contractible filling device such as an air bag or bladder.

[0035] The return path P3 serves to recover fluid during pressure relief. In this embodiment, the return path P3 can be divided into a first return path P31 and a second return path P32. The inlet end 102 of the supply unit 10 is connected to the second return path P32, and the outlet end 101 is connected to the first path P1. Specifically, the second return path P32 connects the switching unit 20 to the supply unit 10. The switching unit 20 can provide a bypass channel as the first return path P31. When the switching unit 20 is closed and does not supply fluid to the fluid receiving device 30, the first return path P31 can serve as part of the return path P3. When the fluid receiving device 30 is depressurized, the fluid can flow through the second path P2, the switching unit 20, and the second return path P32 to the supply unit 10.

[0036] When the gas output from the supply unit 10 is supplied to the first path P1 to increase the gas volume within the first path P1, the switching unit 20 is activated, allowing the pressurized gas to be instantly released to the fluid receiving device 30 through the second path P2. This instantaneous change in volume within the fluid receiving device 30 creates a massaging effect within the fluid receiving device 30. The fluid receiving device 30 then transfers the pressurized gas from the fluid receiving device 30 via the return path P3 to the supply unit 10 via the first return path P31 and the second return path P32. This cyclic expansion and contraction design creates a cyclical actuation of the pulsating pressure control device.

[0037] The pressures P1 within the first path, P2 within the second path, and P3 within the return path vary in a cycle as follows. During pressure increase, the pressure path changes to the first path P1. When the pressure within the first path P1 is higher than that within the second path P2 (i.e., P1>P2), the switching device 20 opens the connection between the first path P1 and the second path P2, allowing the pressure within the first path P1 to push the fluid toward the second path P2. This allows the second path P2 to fill the fluid receiving device 30 with fluid. During pressure reduction, the pressure within the second path P2 is higher than that within the return path P3 (i.e., P2>P3). The switching device 20 opens the connection between the second path P2 and the return path P3, allowing the pressure within the second path P2 to push the fluid toward the return path P3, thereby allowing the fluid to flow back to the supply unit 10. This cyclical, pulsating pressure cycle causes the fluid receiving device 30 (air bag or bladder) to repeatedly expand and contract.

[0038] Thus, the pulsating pressure control device of the present invention can instantly control the fluid receiving device 30 to produce a cyclic expansion and contraction motion in a very short period of time, for example, 10 cycles in 1 second, or 50 cycles in 10 seconds. Through the instantaneous repeated expansion and contraction, the user experiences a pulse massage effect similar to that of a pulse massage. The pulsating pressure control device of the present invention can be used, for example, as a seat massage device in transportation vehicles.

[0039] Second embodiment

[0040] like Figure 2As shown, compared to the first embodiment, the pulsating pressure control device of the present invention can also include a pressure regulating space 40 to provide an additional pressure boosting function. In the diagram of this embodiment, the pressure regulating space 40 is connected to the switching unit 20, wherein the fluid volume in the pressure regulating space 40 is pressurized and can be transmitted to the switching unit 20. When the switching unit 20 is turned on, the pressurized fluid volume in the pressure regulating space 40 is transmitted to the fluid receiving device 30 via the second path P2, causing the volume of the fluid receiving device 30 to immediately expand, providing another pressure regulating function, creating an effect similar to adding force during a massage.

[0041] In addition to being connected to the switching unit 20, the pressure-regulating space 40 can also be connected to the supply unit 10 or the first path P1. When the pressure-regulating space 40 is directly connected to the supply unit 10, the pressurized fluid in the pressure-regulating space 40 is transferred to the switching unit 20 via the first path P1. When the switching unit 20 is turned on, the pressurized fluid in the pressure-regulating space 40 is transferred to the fluid receiving device 30 via the second path P2, similarly providing a massage effect that increases massage force.

[0042] Furthermore, when the pressure-regulating space 40 is connected to the first path P1, the fluid volume in the pressure-regulating space 40 is pressurized and then transmitted to the switching unit 20 via the first path P1. When the switching unit 20 is turned on, the pressurized fluid volume in the pressure-regulating space 40 is transmitted to the fluid receiving device 30 via the second path P2, similarly producing an effect similar to adding force to a massage. Therefore, regardless of whether the pressure-regulating space 40 of the present invention is connected to the supply unit 10, the first path P1, or the switching unit 20, the effect similar to adding force to a massage can be achieved, and further details will not be provided here.

[0043] Third embodiment

[0044] like Figure 3As shown, the pulsating pressure control device of the present invention also includes a control unit 22, which is disposed between the switching unit 20 and the fluid receiving device 30. More specifically, the control unit 22 is an electronic control unit (ECU) controller that can be used in a vehicle. The control unit 22 includes at least one control circuit 221 and at least one valve 222 with a switching function. The valve 222 in this embodiment can be any valve with a switching function. The control circuit 221 can be a microcontroller (MCU). More specifically, the control circuit 221 can integrate a central processing unit (CPU), memory, input / output interfaces, and a timer / counter on a single semiconductor circuit board. The control circuit 221 controls multiple valves 222 with a switching function. Each valve 222 can control at least one fluid receiving device 30, such as an airbag in a vehicle. This provides a user with a control interface corresponding to input / output, thereby enabling individual control of the pulsating pressure control module of this embodiment, such as the airbag position, operation time, massage intensity, etc. of a seat massage system in a vehicle.

[0045] According to the above-mentioned pulsating pressure control device, the operation steps of the pulsating pressure control device of the present invention are as follows: a pulsating signal of a default pressure and flow is provided to the supply unit 10, and the supply unit 10 outputs the fluid according to the default pressure and flow of the pulsating pressure signal. Specifically, Figure 4 As shown, the pulsating pressure signal of the preset pressure and flow is a control value generated based on a pulsating curve of real-time pressure and corresponding capacity. The pulsating curve can have different default 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, transmitted to the supply unit 10, and then provide different fluid volumes to the fluid receiving device 30, forming an instantaneous expansion effect of different volumes, which functions like providing different massage effects. Curve A and curve B can have the same expected flow Fc at the same pressure Pc. The pulsating curve can be set in the electronic control unit C, specifically, it can be stored in a memory, and can be used through a human-machine interface for the user to select different pulsating curves corresponding to different massage modes.

[0046] In summary, with the cyclical pulsating pressure control device of this invention, when gas output from the fluid supply unit is supplied to the first path to increase the gas volume in the first path, the switching unit is activated, allowing the pressurized gas volume to be instantly released to the fluid receiving device through the second path, thereby causing a momentary change in the volume within the fluid receiving device, producing a percussive and pressing effect similar to a massage function. When the fluid receiving device releases pressure, the switching unit opens the connection between the second path and the return path, transferring the fluid through the return path to the original supply unit, thus repeating the cycle of fluid pressurization and depressurization.

[0047] [Beneficial Effects of Embodiments]

[0048] In this way, the pulsating pressure control device of the present invention can instantly control the fluid receiving device 30 to produce a cyclic action of expansion and contraction in a very short period of time, for example: 10 cyclic actions are produced in 1 second, or 50 cyclic actions are produced in 10 seconds. Through the instantaneous repeated expansion and contraction, the pulse massage user can feel the effect of a pulse massage. At the same time, the cyclic expansion and contraction design is utilized to make the pulsating pressure control device produce a cyclic cyclic action.

Anyone with ordinary skill in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention.
