Description

Technical Field

[0001] Embodiments of the present invention are directed to a lightweight pressurized gas supply system that includes a noise suppression mechanism and a heat dissipation mechanism. Background Art

[0002] Conventional lightweight pressurized gas supply systems, such as desktop or portable air pumps, generally have many disadvantages. For example, conventional lightweight air pumps generally do not have an effective mechanism for shielding the noise generated during operation. The noise generated by the air pump can cause discomfort and annoyance to the user and nearby people.

[0003] Furthermore, the heat generated during the operation of conventional lightweight air pumps is often difficult to effectively control. The air pump may need to be shut down after long periods of continuous use. Such a shutdown would disrupt the continuity of the working process.

[0004] Traditional lightweight air pumps also have problems with inaccurate and inconsistent output air pressure control. For example, some traditional lightweight air pumps control air pressure by stopping the air pump when the air pressure reaches a target value and restarting the air pump operation when the air pressure is insufficient. Frequent starting and restarting of the air pump will cause instantaneous high current, which will affect the life of the air pump parts. Therefore, it is necessary to improve the design and operation of traditional lightweight air pumps. Summary of the invention

[0036] The structural principle and working principle of the present invention are described in detail below in conjunction with the accompanying drawings:

[0037] The specific details of the present invention will be presented in the subsequent description. However, it is understood that embodiments of the present invention can be implemented without these specific details. In other cases, circuits, structures and techniques are not disclosed in detail to avoid obscuring the understanding of the content. However, it is clear to those skilled in the art that the present invention can be implemented without these specific details. It is clear to those of ordinary skill in the art that appropriate functions can be achieved from the description provided without undue experimentation.

[0038] The present invention describes a programmable pressure-regulated gas supply system. The system provides pressurized air (pressurized air) to a spraying device, which can be a handheld spraying device or a spraying device for an automatic makeup machine. The gas supply system of the present invention includes an air pump assembly, which is coupled to a programmable control device. A detector measures the characteristics (e.g., air pressure) of the compressed gas in the gas outlet pipe of the gas supply system in real time. The detected air pressure is sent back to the control device for interpretation, and a control signal is sent to the air pump assembly to adjust the air pressure based on the interpretation of the control device. When the air pressure is below a low threshold, the control signal increases the speed of the air pump motor. When the air pressure is below a high threshold, the control signal decreases the speed of the air pump motor. The control device also sends instructions to a gas outlet valve (e.g., a solenoid valve) to control the opening and closing of the gas outlet valve. The solenoid valve can be driven by an electric current or air pressure. The gas supply system can be connected to the spraying device. When the output port of the valve is open, the gas supply system outputs compressed gas to the spraying device. When the output port of the valve is closed, the flow of compressed gas to the spraying device stops. In one embodiment, the valve further includes an exhaust port, which is used to release the gas into the environment. Therefore, the air pump can continue to operate during use, thereby extending the life of the air pump components. There is no need to frequently start and shut down the air pump.

[0039] In one embodiment, the air pump assembly includes an air pump device, which is located inside two or more sealed boxes (e.g., an inner sealed box and an outer sealed box). The sealed box can be made of metal or hard plastic to reduce the resonance effect of sound waves on the material. A first set of springs is arranged between the air pump device and the inner sealed box, and a second set of springs is arranged between the outer sealed box and the inner sealed box. The first set of springs absorbs the vibrations generated during the operation of the air pump device to reduce the vibrations transmitted to the inner sealed box. The inner sealed box limits the noise generated by the operation of the air pump to the inner sealed box. The second set of springs absorbs the vibrations of the inner sealed box to reduce the vibrations transmitted to the outer sealed box. The outer sealed box limits the noise generated by the vibration of the inner sealed box to the outer sealed box to achieve a noise reduction effect. In one embodiment, the air pump device can be arranged in more than two sealed boxes. The sizes of these sealed boxes gradually decrease and form a set of nested boxes. A set of springs is arranged between any two adjacent sealed boxes. The sizes of these sealed boxes are close. For example, the diameter or diagonal length of the inner sealed box may be 100 mm to 150 mm, and the height may be 150 mm to 200 mm, while the diameter or diagonal length of the outer sealed box may be 150 mm to 200 mm, and the height may be 200 mm to 250 mm.

[0040] In one embodiment, the system includes an air inlet pipe and an air outlet pipe to transfer air into or out of the air pump device through the inner and outer sealed boxes. The system also includes a liquid circulation pipe, which carries a coolant to discharge the heat generated by the air pump device to the outside of the outer sealed box. In one embodiment, the air inlet pipe, the air outlet pipe, and the liquid circulation pipe are all made of flexible materials to reduce vibration transmission. These pipes pass through corresponding holes on the walls of the inner and outer sealed boxes. Any gaps between the pipes and the holes are tightly sealed.

[0041] Figure 1Schematic diagram of one embodiment of a programmable pressure regulated gas supply system (system 10). In this embodiment, system 10 includes a programmable control device 100 ("control device 100") and an air pump assembly 200. Control device 100 includes a programmable control board 101, which includes a circuit board including processing circuits for processing input instructions and signals and generating output control signals and commands. Control device 100 further includes a memory storage device 103, which is used to store the configuration of system 10 and instructions that can be executed by programmable control board 101. Control device 100 receives input from air pressure detector 102, which detects the air pressure of pressurized air output by air pump assembly 200. In addition, system 10 may include an air flow meter to measure the flow rate of compressed gas during operation of the air pump device. Air pressure detector 102 may be replaced by a different detector or a different measuring device. The programmable control board 101 can convert the measured value or detected data into an air pressure value or other quantifiable index to adjust the speed of the air pump motor.

[0042] In one embodiment, the programmable control board 101 may include a microprocessor, a microcontroller, a digital signal processor, a microcomputer, a central processing unit, a logic circuit, an analog circuit, a digital circuit, and any device that operates according to an operation instruction. The memory storage device 103 may be a read-only memory, a non-permanent memory, a permanent memory, a static memory, a dynamic memory, a flash memory, and any device that can store digital information.

[0043] The air pump assembly 200 can supply compressed air to the spraying device 300, which can be part of an automatic makeup machine. The air pump assembly 200 is equipped with a mechanism for noise reduction and heat dissipation, and these details will be described in detail later.

[0044] In one embodiment, the air pump assembly 200 receives power from a power source, such as a power distribution board 500. In one embodiment, the power distribution board 500 can be attached to the air pump assembly 200. The power distribution board 500 can supply power to the entire system 10.

[0045] Figure 21 is a more detailed schematic diagram of an embodiment of the system 10. In this embodiment, the programmable control board 101 receives the air pressure measurement value sent back by the air pressure detector 102, and compares the air pressure measurement value with a preset value. When the air pressure measurement value is greater than the preset value or greater than the high threshold, the programmable control board 101 sends a control signal to the air pump controller 111 to reduce the speed of the air pump motor 209. When the air pressure measurement value is less than the preset value or less than the low threshold, the programmable control board 101 sends a control signal to the air pump controller 111 to increase the speed of the air pump motor 209. The control signal is a programmable value for setting the motor speed. In order to reduce noise, the air pump assembly 200 includes a noise reduction component 240, such as a spring, and allows the air pump device 229 to be housed in two or more sealed boxes. In order to dissipate heat, the air pump assembly 200 includes a liquid cooling component 250 to take away the heat generated by the air pump device 229. The water filter cup 112 collects water condensed due to gas pressurization. The pressurized gas is output to the spraying device 300 through the gas outflow valve 113 (e.g., solenoid valve). The programmable control board 101 controls the operation of the gas outflow valve 113 according to the instructions in the program. In one embodiment, the gas outflow valve 113 can be a three-way solenoid valve with a spraying mode and an idle mode. In the spraying mode, the programmable control board 101 switches the output of the valve to the spraying device 300 and increases the speed of the air pump motor 209 to increase the air pressure. In the idle mode, the programmable control board 101 switches the output of the valve to the exhaust port, releases the gas into the environment and reduces the speed of the air pump motor 209.

[0046] Figure 3 : is a schematic diagram of an embodiment of the system 10 connected to the automatic makeup machine 400. The system 10 can be externally connected to the automatic makeup machine 400. The automatic makeup machine 400 can spray the skin spray product onto the user's face. The automatic makeup machine 400 includes a three-dimensional moving device 401, a spraying device 300, and a control circuit 403. The control circuit 403 is electrically connected to the three-dimensional moving device 401 to control the movement of the three-dimensional moving device 401 and the spraying device 300. The control circuit 40 is also electrically connected to the control device 100 of the system 10. The air pressure output by the air pump assembly 200 can be detected in real time through the air pressure detector 102. The control device 100 provides a control signal to the air pump assembly 200 according to the program instructions and the air pressure. The air pump assembly 200 outputs compressed gas to the spraying device 300. Please refer to Figure 1 The programmable control board 101 in the control device 100 can receive program instructions from the control circuit 403 or the memory storage device 103 to deliver the compressed gas to the spray device 300. The compressed gas generated by the air pump assembly 200 can be directly delivered to the spray device 300 without being stored in a gas tank.

[0047] The control circuit 403 can be implemented by coupling a processing unit to a storage unit. The processing unit can be a microprocessor, a microcontroller, a digital signal processor, a microcomputer, a central processing unit, a logic circuit, an analog circuit, a digital circuit, and any device that can operate according to an operation instruction. The storage unit can be a read-only memory, a non-permanent memory, a permanent memory, a static memory, a dynamic memory, a flash memory, and any device that can store digital information.

The air pump assembly 200 includes an outer sealed box 211, and the outer sealed box 211 includes a power input hole 201A for receiving input power, a gas outflow pipe 202 for outputting compressed gas, and a gas inflow hole 203A. The air pump assembly 200 further includes a liquid cooling assembly 250 (such as a liquid cooling assembly 250) located outside the outer sealed box 211. Figure 2 213). The internal components of the outer sealed box 211 are not drawn. The liquid cooling assembly 250 includes a heat sink 213, a liquid pump 214, and a liquid circulation pipe 204. A cooling fan 218 is located on top of the heat sink 213. The liquid circulation pipe 204 includes a first section connecting the liquid pump 214 to the interior machinery, a second section connecting the interior machinery to the heat sink 213, and a third section connecting the heat sink 213 to the liquid pump 214. The liquid pump 214 sends cooling into the liquid circulation pipe 204 so as to transfer the heat generated by the internal equipment of the air pump assembly 200 to the heat sink 213.

[0049] Figure 5 2 is a schematic diagram of an embodiment of the inner sealed box 210. The inner sealed box 210 is located inside the outer sealed box 211 and contains the air pump device 229 (such as Figure 2 The inner sealed box 210 includes a power input hole 201B for receiving input power, a gas outflow pipe 202 for outputting compressed gas, and a gas inflow hole 203B. The gas inflow pipe passes through the gas inflow hole 203A on the outer sealed box 211 (as shown in FIG. Figure 4 As shown) and the gas inlet hole 203B on the inner sealed box 210 provide input gas to the air pump device 229. Figure 5 A portion of the liquid circulation pipe 204 and a portion of the gas outflow pipe 202 are shown. A set of springs 212B are provided on all sides of the inner sealed box 210 and between the inner sealed box 210 and the outer sealed box 211 to absorb air vibrations generated when the inner sealed box 210 vibrates.

[0050] Figure 6 for Figure 5Schematic diagram of an embodiment of an air pump device 229 in an inner sealed box 210. The air pump device 229 includes an air pump motor 209, a compressor 219, and a heat-conducting metal box ("metal box 205"). The air pump motor 209 receives power from a power input line 201, and the power input line 201 is respectively connected to the power input hole 201A (such as Figure 4 ) and the power input hole 201B (as shown Figure 5 The compressor 219 receives gas from the gas inlet pipe 203, and the gas inlet pipe 203 respectively passes through the gas inlet holes 203A (as shown in FIG. Figure 4 ) and the gas inlet hole 203B (as shown Figure 5 210) enters the outer sealed box 211 and the inner sealed box 210. A set of springs 212C surrounds all sides of the air pump device 229 and is disposed between the air pump device 229 to absorb vibrations generated during the operation of the air pump device 229. In this way, the springs 212C reduce the vibrations transmitted to the inner sealed box 210, achieving a noise reduction effect.

[0051] In one embodiment, the liquid circulation pipe 204 includes a metal section (referred to as "metal pipe 206") that partially surrounds the air pump motor 209. The coolant in the liquid circulation pipe 204 flows through the metal pipe 206 to remove the heat generated by the air pump motor 209, and continues to flow through the metal box 205 for cooling. The coolant in the liquid circulation pipe 204 continues to flow to the heat sink 213 (such as Figure 4 During the operation of the air pump assembly 200, the coolant in the liquid circulation pipe 204 continues to circulate.

[0052] The inner sealed box 210 and the outer sealed box 211 are sealed. That is, all gaps between the pipes / tubes and the corresponding holes on the walls of the inner sealed box 210 and the outer sealed box 211 are tightly sealed, and there are no other openings on the inner sealed box 210 and the outer sealed box 211. The inner sealed box 210 and the outer sealed box 211 provide a closed environment to isolate the noise generated by the air pump device 229 to achieve a noise reduction effect. In some embodiments, the air pump assembly 200 may include more than two sealed boxes to accommodate the air pump device 229, and a group of springs are provided between any two adjacent sealed boxes and between the air pump device 229 and the innermost sealed box.

[0053] Figure 7 yes Figure 4 Schematic diagram of an embodiment of the air pump assembly 200. In order to more clearly present the liquid circulation pipe 204 and the connection between the liquid circulation pipe 204 and the air pump device 229, the inner sealed box 210 and the outer sealed box 211 are presented in the form of transparent boxes drawn with dotted lines. It is understandable that the inner sealed box 210 and the outer sealed box 211 can be made of opaque materials. Figure 4 , Figure 5 and Figure 7 In the illustrated embodiment, the inner sealed box 210 and the outer sealed box 211 can each be in the shape of a cube or a cuboid. In alternative embodiments, the sealed box can be any three-dimensional shape that can accommodate the air pump device 229. Non-limiting examples of three-dimensional shapes include squares (e.g., cubes), rectangles (e.g., cuboids), circles (e.g., cylinders or spheres), parallelograms, ellipses, and irregular shapes.

[0054] Figure 8 800 is a schematic diagram of another embodiment of the air pump assembly 800. Please refer to Figures 4 to 7 , except that the shape of the sealed box and the arrangement of the air pump device 229 and the liquid circulation pipe 204 are different, the air pump assembly 800 has the same elements as the air pump assembly 200. In this embodiment, the air pump assembly 800 includes an inner sealed box 810 and an outer sealed box 811, wherein the inner sealed box 810 and the outer sealed box 811 are both cylindrical. In order to simplify the drawings and facilitate understanding, Figure 8 The inner sealed box 810 and the outer sealed box 811 are both presented as transparent boxes drawn with dotted lines. It is understandable that the inner sealed box 810 and the outer sealed box 811 can be made of opaque materials. In the present embodiment, the metal box 205 is located below the compressor 219 and the air pump motor 209. The liquid cooling components (such as the liquid pump 214 and the heat sink 213) not shown in this figure can be located on the top of the outer sealed box 811. The liquid circulation pipe 204 is led out from the opposite sides of the inner sealed box 810 and the outer sealed box 811 to reach the liquid cooling components; that is, the liquid circulation pipe 204 passes through the bottom surface of the inner sealed box 810 and the top surface of the outer sealed box 811. Therefore, the liquid circulation pipe 204 passes through the space between the inner sealed box 810 and the outer sealed box 811 at least along the entire length (i.e., height) of the inner sealed box 810. As shown Figure 8 As shown, increasing the length of the liquid circulation pipe 204 can further enhance the noise reduction effect, because the elasticity of the liquid circulation pipe 204 can suppress the vibration generated by the inner sealed box 810 and transmitted to the outer sealed box 811.

[0055] Fig. 9 This is a schematic diagram of another embodiment of the air pump assembly. Please refer to Figures 4 to 7, except that the arrangement of the air pump device 229 and the liquid circulation pipe 204 is different, the air pump assembly 900 has the same elements as the air pump assembly 800. In this embodiment, the metal box 205 is located above the compressor 219 and the air pump motor 209. The liquid cooling components (such as the liquid pump 214 and the heat sink 213) not shown in this figure can be located on the top of the outer sealed box 811. The liquid circulation pipe 204 is led out from the same side of the inner sealed box 810 and the outer sealed box 811 to reach the liquid cooling components; for example, it passes through the top surface (round side) of the inner sealed box 810 and the outer sealed box 811 shown in the figure. This arrangement is a variation of the air pump assembly 200, in which the liquid circulation pipe 204 passes through the same side of the inner sealed box 210 and the outer sealed box 211 (such as: both from the top surface). In another embodiment, the liquid circulation pipe 204 can pass through the same side of the inner sealed box 210 and the outer sealed box 211 other than the top surface.
