Abstract
Description
Technical Field
[0001] This invention relates to the field of controller technology, and in particular to a controller and a gas-using device. Background Technology
[0002] In related technologies, the controllers of existing gas-using equipment are generally closed structures, which results in high pressure inside the controller and high temperature rise after long-term use. This affects the switching function of the solenoid valve and the reliability and stability of the controller, leaving room for improvement. Summary of the Invention

[0006] According to the controller of the present invention, the gas in the flow channel can overflow and be depressurized by passing through the heat dissipation hole that connects the flow channel and the mounting cavity in sequence. The overflowed and depressurized gas can flow through the solenoid valve and circuit board in the mounting cavity for heat dissipation. At the same time, the heat dissipation hole can spontaneously leak gas when the flow channel pressure is high to keep the flow channel pressure stable.

[0009] In some embodiments, each of the valve bodies has at least one heat dissipation hole in its air inlet and air outlet portions.
[0010] In some embodiments, the valve body includes a plurality of valve bodies, the plurality of valve bodies including: a first valve body, the first valve body being disposed upstream of the flow channel, the air inlet of the first valve body communicating with the outside of the control housing, and the air outlet of the first valve body communicating with the flow channel; and a second valve body, the second valve body being disposed downstream of the flow channel, wherein in two adjacent sections of the flow channel, the air inlet of the second valve body is communicating with one of the two sections, and the air outlet of the second valve body is communicating with the other of the two ends.
[0011] In some embodiments, a port is formed at the connection between two adjacent sections of the flow channel for installing the valve body; the control component further includes: at least one plug, the sum of the number of the plug and the valve body is equal to the number of the ports, and each plug is used to plug the port.
[0012] In some embodiments, each of the sealing members is provided with at least one of the heat dissipation holes.
[0013] In some embodiments, the heat dissipation holes include a plurality of holes, and the valve body includes a plurality of valve bodies. The plurality of heat dissipation holes are partitioned and disposed on the plurality of valve bodies for partitioned heat dissipation of the plurality of valve bodies.
[0014] According to some embodiments of the present invention, the wall of the flow channel is provided with at least one of the heat dissipation holes.
[0015] According to a second aspect of the present invention, a gas-using device includes: an airbag and a controller according to a first aspect of the present invention, wherein the airbag is connected to the downstream of the flow channel, and the controller is adapted to control the inflation and deflation of the airbag. By employing the above-mentioned controller, the response speed of the opening and closing of multiple valves can be improved, and the reliability and stability of the gas-using device can be improved.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] The following is for reference. Figures 1-17 A controller 100 according to an embodiment of the present invention is described.
[0023] like Figures 1-17As shown, the controller 100 according to an embodiment of the present invention includes: a control housing 10, which may define a flow channel 111 and a mounting cavity 12. The flow channel 111 is used to transport gas. The mounting cavity 12 may house control components such as a solenoid valve and a circuit board. The circuit board can control the opening and closing of the solenoid valve. For example, the solenoid valve may be a valve body disposed in the flow channel 111, so that the circuit board can control the opening and closing of the valve body to control the flow of gas along the flow channel 111. Alternatively, the solenoid valve may be a component outside the flow channel 111, and the solenoid valve may be linked with the component outside the flow channel 111, so that the circuit board can control the opening and closing of the solenoid valve to achieve other functions.
[0024] The flow channel 111 and the mounting cavity 12 can be connected through at least one heat dissipation hole 30, and the mounting cavity 12 can be connected to the outside of the control housing 10. This allows the gas in the flow channel 111 to overflow and be depressurized sequentially through the heat dissipation hole 30 and the mounting cavity 12, achieving stable overflow of the gas in the flow channel 111. That is, the heat dissipation hole 30 can spontaneously leak gas when the pressure in the flow channel 111 is high, so as to keep the gas pressure in the flow channel 111 stable. This achieves constant pressure reduction of the gas in the flow channel 111 and ensures the safe operation of the controller 100. It can also improve the pressure relief effect of the controller 100. At the same time, the depressurized gas can flow through the solenoid valve and circuit board in the mounting cavity 12, which can achieve heat dissipation of the solenoid valve and circuit board, improve the cooling effect of the controller 100, and thus ensure the normal operation of the controller 100 and improve the reliability and stability of the controller 100.
[0025] It is understandable that the heat dissipation hole 30 can be set relative to or adjacent to the control element that needs to be dissipated, which can improve the heat dissipation effect of the control element. Furthermore, the heat dissipation hole 30 can include multiple holes, and the multiple heat dissipation holes 30 can be set in zones, so that the number and area of the heat dissipation hole 30 can be allocated according to the heat generation of different control elements, and the zoned heat dissipation and cooling of the control element can be realized.
[0026] For example, for control components with low heat generation, the number of heat dissipation holes 30 can be reduced and the multiple heat dissipation holes 30 can be appropriately dispersed. For control components with high heat generation, the number of heat dissipation holes 30 can be increased and the multiple heat dissipation holes 30 can be appropriately concentrated. This can make the allocation of heat dissipation resources more reasonable, improve the heat dissipation effect of control components, and save resources.
[0027] According to the present invention, the controller 100, through a heat dissipation hole 30 connecting the flow channel 111 and the mounting cavity 12, allows gas in the flow channel 111 to overflow and depressurize sequentially through the heat dissipation hole 30 and the mounting cavity 12. The overflowed and depressurized gas can flow through the solenoid valve and circuit board in the mounting cavity 12 for heat dissipation. At the same time, the heat dissipation hole 30 can spontaneously leak gas when the pressure in the flow channel 111 is high, so as to keep the gas pressure in the flow channel 111 stable. This can achieve constant pressure reduction of the gas in the flow channel 111 and ensure the safe operation of the controller 100, thereby improving the pressure relief effect of the controller 100, improving the cooling effect of the controller 100, and improving the reliability and stability of the controller 100. Compared with the solution of using an overflow valve for pressure reduction, the pressure relief by opening the heat dissipation hole 30 can reduce the abnormal noise caused by gas pressure relief, reduce the noise of the controller 100, and improve the user experience.
[0028] like Figure 1 As shown, according to some embodiments of the present invention, the flow channel 111 may include multiple segments, and the multiple flow channels 111 may be connected in sequence. The controller 100 may also include a control component 20, which may be connected to the control housing 10. The control component 20 may block or connect any two adjacent flow channels 111, thereby enabling the control component 20 to control the opening and closing of the flow channel 111 to control the flow of gas along the flow channel 111, which can ensure the normal operation of the controller 100.
[0029] like Figure 1 As shown, in some embodiments, the control component 20 may include at least one valve body, each valve body may be connected to the control housing 10. For example, the flow channel 111 may have a reserved mounting groove, the valve body may be snapped into the mounting groove, and the valve body may be fastened to the control housing 10 by fasteners (such as screws, bolts or bolts). Each valve body may have an air inlet 211 and an air outlet 221, the air inlet 211 is used for air intake of the valve body, and the air outlet 221 is used for air exhaust of the valve body.
[0030] In this configuration, in two adjacent flow channels 111, the air inlet 211 of the valve body can be connected to one flow channel 111, and the air outlet 221 of the valve body can be connected to the other flow channel 111, so that the valve body can control the opening and closing of the two adjacent flow channels 111 to control the flow of gas along the flow channel 111. Alternatively, the air inlet 211 of the valve body can be connected to the outside of the control housing 10, and the air outlet 221 can be connected to the flow channel 111, so that the valve body can control the air intake of the flow channel 111 to control the flow of gas along the flow channel 111.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, each valve body's air inlet 211 and air outlet 221 can be provided with at least one heat dissipation hole 30, that is, each valve body can be provided with at least one heat dissipation hole 30, so that the valve body can be part of the flow channel 111 to open at least one heat dissipation hole 30 for pressure relief and heat dissipation, so that the gas in the flow channel 111 can be depressurized through the heat dissipation hole 30 and the mounting cavity 12 in sequence, and the gas in the flow channel 111 can achieve stable overflow of gas, that is, the heat dissipation hole 30 can spontaneously leak gas when the pressure in the flow channel 111 is high so that the flow channel 111 can maintain stable gas pressure.
[0032] This allows for constant pressure reduction of the gas within the flow channel 111, ensuring the safe operation of the controller 100 and improving its pressure relief effect. Simultaneously, the depressurized gas can flow through the solenoid valve and circuit board within the mounting cavity 12, facilitating heat dissipation for the solenoid valve and circuit board. It also prevents the accumulation of heat-absorbing gas within the mounting cavity 12, further enhancing the heat dissipation of the control components and improving the cooling effect of the controller 100. Consequently, this ensures the normal operation of the controller 100 and improves its reliability and stability.
[0033] like Figure 1 As shown, in some embodiments, the valve body may include multiple valve bodies, which may include at least one first valve body 21 and at least one second valve body 22. The first valve body 21 may be located upstream of the flow channel 111. The air inlet 211 of the first valve body 21 may be connected to the outside of the control housing 10, and the air outlet 221 of the first valve body 21 may be connected to the flow channel 111, so that the opening and closing of the first valve body 21 can control the air intake of the flow channel 111 to control the flow of gas along the flow channel 111.
[0034] It is understood that the first valve body 21 may be provided with at least one heat dissipation hole 30, so that the first valve body 21 can be part of the flow channel 111 to open at least one heat dissipation hole 30 for pressure relief and heat dissipation, which can improve the pressure relief effect of the controller 100, improve the cooling effect of the controller 100, improve the reliability and stability of the controller 100, and at the same time ensure the structural strength of the flow channel 111 and improve the service life of the flow channel 111.
[0035] The second valve body 22 can be located downstream of the first valve body 21 in the flow channel 111. In two adjacent flow channels 111, the air inlet 211 of the second valve body 22 can be connected to one flow channel 111, and the air outlet 221 of the second valve body 22 can be connected to the other flow channel 111, so that the valve body can control the opening and closing of the two adjacent flow channels 111 to control the flow of gas along the flow channel 111.
[0036] It is understood that the second valve body 22 can be provided with at least one heat dissipation hole 30, so that the second valve body 22 can be part of the flow channel 111 to open at least one heat dissipation hole 30 for pressure relief and heat dissipation, which can improve the pressure relief effect of the controller 100, improve the cooling effect of the controller 100, improve the reliability and stability of the controller 100, and at the same time ensure the structural strength of the flow channel 111 and improve the service life of the flow channel 111.
[0037] like Figure 1 As shown, in some embodiments, the control component 20 may further include at least one sealing element 23. The connection between two adjacent sections of the flow channel 111 may be formed with an opening for installing the valve body and the sealing element 23. For example, an installation groove may be reserved between two adjacent sections of the flow channel 111. The two adjacent sections of the flow channel 111 may be connected through the installation groove, and the installation groove may be opened through the opening. The valve body may be snapped into the installation groove through the opening. When the valve body is installed, the air inlet 211 and the air outlet 221 of the valve body may be connected to the two adjacent sections of the flow channel 111 in the installation groove, so that the opening and closing of the valve body can control the flow of gas along the flow channel 111.
[0038] The sealing component 23 can be snapped into the mounting slot through the port, and the sealing component 23 can be fastened to the control housing 10 by fasteners (such as screws, bolts or bolts). After the sealing component 23 is installed, the sealing component 23 can block the port. For example, the sealing component 23 can block the port where no valve body is installed, which can prevent the flow channel 111 from leaking gas when the number of valve bodies is less than the number of ports, and can ensure that the flow channel 111 can transport gas normally under the control of the valve body.
[0039] Specifically, the sum of the number of sealing components 23 and valve bodies can be equal to the number of ports, so that each valve body can be installed in the corresponding position to control the normal flow of gas in the flow channel 111, and each sealing component 23 can block excess ports, which can prevent the flow channel 111 from leaking due to idle ports. At the same time, it can make the disassembly and assembly of valve bodies more convenient, and the layout of valve bodies more flexible. Thus, the flow channel 111 can be redesigned by increasing or decreasing the number of valve bodies or by adjusting the position of the valve bodies, and it is easy to maintain.
[0040] like Figure 1 , Figure 9 and Figure 10 As shown, in some embodiments, each sealing element 23 may be provided with at least one heat dissipation hole 30, so that the sealing element 23 can be part of the flow channel 111 to open at least one heat dissipation hole 30 for pressure relief and heat dissipation, which can improve the pressure relief effect of the controller 100, improve the cooling effect of the controller 100, improve the reliability and stability of the controller 100, and at the same time ensure the structural strength of the flow channel 111 and improve the service life of the flow channel 111.
[0041] In some embodiments, the number of heat dissipation holes 30 may include multiple ones, the number of valve bodies may include multiple ones, and the multiple heat dissipation holes 30 may be partitioned and disposed on multiple valve bodies for partitioned heat dissipation of multiple valve bodies. The multiple valve bodies may be solenoid valves or other forms of control valves that generate heat during operation, and the functions implemented by different valve bodies may be different. For example, the massage air circuit of the controller 100 may be opened and closed by certain valve bodies, or the heating air circuit of the controller 100 may be opened and closed by certain valve bodies.
[0042] Furthermore, the air circuits such as the massage air circuit and the heating air circuit can be divided into multiple branches according to the functional location. For example, multiple branches that can massage or heat the user's head, waist and legs can be opened and closed by certain dedicated valves to achieve functional zoning. Thus, according to the different heat generated by different functional valves, different numbers or positions of heat dissipation holes 30 can be opened for different valves, which can make the heat dissipation resources more reasonable, improve the heat dissipation effect of the valve, and save resources.
[0043] like Figure 9 and Figure 11 As shown, according to some embodiments of the present invention, the pipe wall of the flow channel 111 can be provided with at least one heat dissipation hole 30, so that the body of the flow channel 111 can directly open at least one heat dissipation hole 30 for pressure relief and heat dissipation, which can improve the pressure relief effect of the controller 100, improve the cooling effect of the controller 100, improve the reliability and stability of the controller 100, facilitate processing, and reduce the processing cost of the control component 20.
[0044] In some embodiments, the controller 100 may further include an air supply component, which may be disposed within the control housing 10 and may be disposed adjacent to the heat dissipation hole 30. The air supply component may be connected to the heat dissipation hole 30 and may control the opening and closing of the heat dissipation hole 30. The air supply component may also drive gas to be injected through the heat dissipation hole to the control element for heat dissipation. The air supply component may be an intake valve disposed within the control housing 10, and the gas in the flow channel 111 may serve as the air source for the intake valve. The air supply component may also serve as a switch valve to open and close the heat dissipation hole 30, so that the heat dissipation hole 30 injects airflow to the control element by depressurization. Alternatively, the air supply component may serve as an active valve to actively drive gas to be injected through the heat dissipation hole to the control element.
[0045] According to some embodiments of the present invention, the controller 100 may further include an air supply component, which may be disposed on the control housing 10 and may be connected to the heat dissipation hole 30 through an air supply channel. The air supply channel may be an internal structure of the control housing 10, and the air supply path may be extended to enrich the air source, so that the air supply component may drive the gas outside the control housing 10 to be injected into the control element through the heat dissipation hole 30.
[0046] Of course, the gas source can also be the gas in the flow channel 111 of the control housing 10. The gas supply channel can connect the flow channel 111 and the mounting cavity 12 through the heat dissipation hole 30. The gas supply channel can also connect the flow channel 111 and the mounting cavity 12 separately. That is, the gas in the flow channel can flow to the mounting cavity 12 through the gas supply channel and the heat dissipation hole 30, and then flow back to the flow channel through the gas supply channel. Thus, the gas can circulate through the heat dissipation hole 30 through the gas supply channel to achieve the same part of the gas to circulate heat dissipation for the control element. Furthermore, the control housing 10 can be provided with a separate gas storage structure as a gas source. The gas storage structure is connected to the heat dissipation hole 30 through the gas supply channel, which can improve the sealing of the controller 100 and improve the protection effect of the control element.
[0047] In some embodiments, the controller 100 may further include an exhaust component, at least a portion of which may be disposed within the mounting cavity 12. The mounting cavity 12 may be connected to the external space of the controller 100 via the exhaust component. This exhaust component is used to discharge the heat dissipation exhaust gas that has absorbed heat from the control element within the mounting cavity 12. This can prevent the heat dissipation exhaust gas from accumulating in the mounting cavity 12, improve the heat dissipation effect of the control element, and facilitate the subsequent use of the controller 100. It is understood that the exhaust component may be an air pump.
[0048] like Figure 16 and Figure 17 As shown, according to some embodiments of the present invention, the valve body (such as the first valve body 21 and the second valve body 22) can be a solenoid valve. A heat dissipation hole 30 can be opened at the skeleton 24 of the solenoid valve. When the pressure in the flow channel 111 reaches the set value, the flow channel 111 can overflow through the heat dissipation hole 30, which can reduce the temperature of the enameled wire, improve the heat dissipation effect of the solenoid valve, and realize the overflow of the air-using component (such as the air bag 200). At the same time, it can provide assistance in the initial stage of exhaust in the flow channel 111 to enable it to exhaust quickly.
[0049] like Figure 1 and Figure 9 As shown, according to some embodiments of the present invention, the control housing 10 may include a first housing 11 and a second housing (not shown in the figure). The first housing 11 may define a flow channel 111. The second housing may be connected to the first housing 11, and at least a portion of the second housing and the first housing 11 may be arranged at intervals to form a mounting cavity 12. The mounting cavity 12 may communicate with the outside of the control housing 10 through the gap between the first housing 11 and the second housing.
[0050] This allows the gas in the flow channel 111 to be depressurized sequentially through the heat dissipation hole 30 and the mounting cavity 12, achieving a constant pressure reduction of the gas in the flow channel 111 and improving the pressure relief effect of the controller 100. At the same time, the depressurized gas can flow through the solenoid valve and circuit board in the mounting cavity 12, achieving heat dissipation of the solenoid valve and circuit board and improving the cooling effect of the controller 100. This ensures the normal operation of the controller 100 and improves the reliability and stability of the controller 100. It is understood that the side of the heat dissipation hole 30 facing the mounting cavity 12 can be connected to a nozzle or other air guiding structure (such as an air pipe), which can precisely control the flow direction of the heat dissipation gas, facilitate the discharge of the heat dissipation gas in the mounting cavity 12, prevent the reuse of heat dissipation gas, and improve the heat dissipation effect of the control components.
[0051] like Figure 1 and Figure 9 As shown, the gas-using device 1000 according to an embodiment of the present invention includes: an air bag 200 and a controller 100. The air bag 200 can be connected to the downstream of the flow channel 111. The controller 100 can control the opening and closing of multiple valves to control the inflation and deflation of the air bag 200. By using the controller 100, the response speed of the opening and closing of multiple valves can be improved, and the reliability and stability of the gas-using device 1000 can be improved.
[0052] like Figure 9 As shown, according to some embodiments of the present invention, the airbag 200 can be connected to the flow channel 111 through the connecting pipe 40. The connecting pipe 40 can be provided with at least one heat dissipation hole 30, so that the connecting pipe 40 can be part of the flow channel 111 to provide at least one heat dissipation hole 30 for pressure relief and heat dissipation. This can improve the pressure relief effect of the controller 100, improve the cooling effect of the controller 100, improve the reliability and stability of the controller 100, and at the same time ensure the structural strength of the flow channel 111 and improve the service life of the flow channel 111. The connecting pipe 40 can be a flexible pipe, which is beneficial to the deployment of the airbag 200.
[0053] like Figure 1 and Figure 9 As shown, according to some embodiments of the present invention, by opening multiple heat dissipation holes 30 (such as the heat dissipation holes 30 on the sealing member 23, valve body, flow channel 111 and connecting pipe 40) along the extension direction of the flow channel 111, the gas in the flow channel 111 can be depressurized more uniformly, the gas in the flow channel 111 can be stably overflowed, and the gas in the flow channel 111 can be kept at a constant pressure drop, which can improve the depressurization effect of the controller 100. At the same time, the depressurized gas can flow more uniformly through the solenoid valve and circuit board in the mounting cavity 12, which can achieve heat dissipation of the solenoid valve and circuit board, and improve the cooling effect of the controller 100. This can ensure the normal operation of the controller 100 and improve the reliability and stability of the controller 100.
[0054] Among them, the volume of flow channel 111 is approximately 2 cm³. 3 ~20cm 3 Within this range, the diameter of each heat dissipation hole 30 is approximately in the range of 0.05mm to 0.3mm, which can achieve constant pressure reduction of the gas in the flow channel 111, improve the pressure relief effect of the controller 100, and allow the depressurized gas to flow evenly through the solenoid valve and circuit board in the mounting cavity 12, thereby improving the cooling effect of the controller 100.
[0055] The controller 100 of this application can be used in any pneumatic system. In this application, the airbag 200 can be a massage airbag 200, and the pneumatic device 1000 can be a massage device using the massage airbag 200 or any other pneumatic device. The massage device can be a massager, or it can be a massager that is matched with other products (such as vehicle seats). By using the controller 100 described above, the massage effect of the massager can be improved. The pneumatic device can be used for the lumbar support or leg support of the seat to support the user's body parts, or the pneumatic device can be used as a position adjuster for the seat or other movable device to finely adjust, open or retract the position of the seat or other movable device (such as a table) in three-dimensional space.

[0057] According to some embodiments of the present invention, the gas-using device 1000 may further include an exhaust device. At least a portion of the exhaust device may be installed in the interior space of the seat, and the portion of the exhaust device located inside the gas-using device 1000 may be disposed adjacent to the controller 100. The interior space of the seat (the exterior space of the controller 100) may be connected to the exterior space of the seat through the exhaust device, so that the exhaust device may discharge the exhaust gas that still exists inside the seat after the controller 100 stops working. This can prevent the heat dissipation exhaust gas from accumulating in the interior space of the seat, improve the heat dissipation effect of the controller 100, and facilitate the subsequent use of the gas-using device 1000. It is understood that the exhaust device may include an air pump.
