Abstract
Description
Technical Field
[0001] This invention relates to the field of air pump technology for inflation and deflation, and more specifically, to an air pump device for rapid inflation and deflation. Background Technology
[0002] Currently, existing air pumps are used in many applications with inflatable products (such as air mattresses, inflatable toys, tires, etc.). Traditional air pumps deliver airflow through a single path: air enters the inflatable product through the pump during inflation and exits through the same path during deflation. However, this single-path design can lead to low inflation and deflation efficiency, especially in situations requiring rapid inflation or deflation, resulting in longer processing times. For many inflatable products, shortening inflation and deflation times is crucial, affecting not only user experience but also pump efficiency. Traditional air pumps may be limited by exhaust pressure during inflation, resulting in a slow inflation process; similarly, the exhaust airflow may be restricted during deflation, leading to prolonged deflation times. Consequently, air pumps consume more electricity when inflating and deflation products, which contradicts the energy-saving and environmentally friendly trends in industrial products. Summary of the Invention
[0003] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a rapid inflation and deflation air pump device to achieve the effects of increasing airflow, reducing inflation and deflation time, and reducing power consumption.
[0004] The technical solution adopted by this invention is a rapid inflation / deflation air pump device, the air pump device comprising:
[0005] The housing has a vent valve on its front side for connecting the air pump device and the inflatable product;
[0006] The top cover, which cooperates with the shell to form an internal cavity, has a ventilation port on it for communicating with the outside.
[0007] A fixed bracket is disposed in the internal cavity, including several vents and several inlets, and a power switch is provided on the top of the fixed bracket;
[0008] The exhaust module, mounted on the fixed frame, includes a drive assembly and a blower assembly, used to increase the airflow at the air inlet and accelerate the gas flow in the device;
[0009] An airway switching module includes a knob assembly and an airway switching block; the airway switching block is disposed in the fixed bracket and is connected to the power switch and the ventilation valve respectively; the knob assembly is connected to the top of the airway switching block, passes through the top cover and protrudes outside the device, and is used to control the airway switching block to quickly switch the ventilation ports by operating the knob assembly outside the device, while simultaneously controlling the opening and closing of the power switch and the ventilation valve.
[0010] In this invention, by setting several vents and several inlets on the fixed bracket, and using an airway conversion module in conjunction with the fixed bracket, rapid switching of the vents is achieved. Simultaneously, a suction module is used to increase the airflow at the inlets and accelerate the gas flow rate, thereby enabling rapid inflation and deflation of the inflatable product. This effectively reduces inflation and deflation time, lowers energy consumption, and improves the efficiency and stability of the entire air pump device. Furthermore, this application utilizes the interlocking of a knob assembly, an airway conversion block, and a power switch. By turning the knob assembly to move the airway conversion block to a specific position, the vent valve is opened while the power switch is activated, causing the suction assembly to begin operation. This effectively improves the working stability of the air pump while simultaneously achieving inflation and deflation.
[0011] Preferably, the fixing bracket includes a bracket body and a back cover. The front side of the bracket body is provided with a first vent, which is connected to the vent valve. The upper rear side of the bracket body is provided with a second vent and a third vent, and the lower rear side is provided with a first air inlet. The back cover is connected to the rear side of the bracket body to form a receiving cavity. The upper part of the back cover is provided with a sealing surface and an opening. The sealing surface is connected to the second vent, and the opening is connected to the third vent. The lower part of the back cover is provided with a second air inlet.
[0012] By cooperating with the support body and the back cover, gas can flow from multiple different ports when inflating or deflating the inflatable product, thereby effectively increasing the flow rate and reducing the inflation / deflating time.
[0013] Preferably, the blower assembly is a fan blade and is disposed in the accommodating cavity, forming several air intake passages in conjunction with the first air inlet and the second air inlet.
[0014] The fan blades allow airflow to enter the blower assembly from the first and second air inlets respectively for acceleration, which not only increases the airflow velocity but also the airflow volume, achieving dual-path inflation and deflation, effectively reducing inflation and deflation time and improving work efficiency.
[0015] Preferably,
[0016] When inflating
[0017] The ventilation valve, the first ventilation port, the airway switching block, the second ventilation port, and the accommodating cavity are connected to form a first airway;
[0018] The air exchange port is connected to the gap formed by the support body and the housing and the first air inlet to form a second air passage;
[0019] The air exchange port is connected to the gap formed by the support body and the housing, the third air vent, the opening, the gap formed by the back cover and the housing, and the second air inlet to form a third air passage;
[0020] By twisting the knob assembly, the airway switching block is moved to the first airway and connected to the second air inlet. At the same time, the power switch is turned on to start the drive assembly and make the fan blade rotate. The outside air entering from the air inlet can enter the fan blade through the second and third airways for airflow acceleration, and then enter the inflatable product through the first airway.
[0021] When deflation occurs
[0022] The ventilation valve, the first ventilation port, the airway conversion block, the third ventilation port, the opening, the gap formed by the back cover and the housing, and the second air inlet are connected to form a fourth airway;
[0023] The gap formed by the ventilation valve, the support body and the housing and the first air inlet are connected to form a fifth air passage;
[0024] The accommodating cavity, the second vent, the gap formed by the support body and the housing, and the air exchange port are connected to form a sixth air passage;
[0025] By turning the knob assembly, the air duct switching block is moved to the fourth air duct and connected to the third air inlet. At the same time, the power switch is turned on to start the drive assembly and make the fan blade rotate. The gas discharged from the inflatable product can enter the fan blade through the fourth and fifth air ducts for airflow acceleration, and then be discharged to the outside through the sixth air duct.
[0026] In this application, the inflation and deflation of the inflatable product can be achieved by moving the airway switching block to connect it to the second or third airway. Moreover, whether it is inflation or deflation, air can be circulated through multiple airways, thereby effectively increasing the airflow and reducing the inflation and deflation time, achieving rapid inflation and deflation of the inflatable product, and effectively reducing power consumption.
[0027] Preferably, the airway switching block has a front-to-back connected structure and an internal partition plate. The partition plate has an "M" shaped structure and is connected to the ventilation valve to control the opening and closing of the ventilation valve. A protrusion is also provided on the top of the airway switching block to cooperate with the power switch to control the power switch.
[0028] The partition plate in the airway conversion block can effectively control the gas to enter the blower assembly through different routes for airflow acceleration. It can also realize the opening and closing of the ventilation valve. Furthermore, the top protrusion of the airway conversion block can control the power switch when the airway conversion block moves, thus making the structure of the entire air pump more compact. Only the control knob component is needed to control the inflation, deflation, or stop status of the entire device, simplifying operation and improving the user experience.
[0029] Preferably, the vent valve includes a push rod, the bottom of which is provided with a control rod. The top of the control rod is in contact with the partition plate. When the control rod abuts against the top two sides of the partition plate, the partition plate exerts a forward force on the push rod, causing the vent valve to open and the air pump device to be in an inflating or deflating state. When the control rod abuts against the recess in the middle of the partition plate, the partition plate retracts the force exerted on the push rod, causing the vent valve to close and the air pump device to stop working.
[0030] By utilizing the partition plate and the top rod to abut against each other, when the airway conversion block moves to the second or third airway, the control rod abuts against both sides of the top of the partition plate, and the air valve is opened to allow inflation or deflation. When the airway conversion assembly is moved between the second or third airway, the control rod abuts against the recess in the middle of the partition plate, and the air valve is closed. At this point, the entire device is in a stopped working state, effectively enhancing the stability and reliability of the air pump.
[0031] Preferably, the vent valve further includes a cover, a spring, and a pressure plate connected in sequence. The cover has a hole for ventilation. The pressure plate passes through the spring and is connected to the cover. A sealing ring is also fitted on the pressure plate to prevent gas leakage. The pressure plate is snapped into the top rod. When the exhaust module is working, the spring is compressed under the pressure of the top rod, causing the pressure plate to move toward the cover, thereby opening the vent valve.
[0032] In this application, when the vent valve is opened, the pressure plate is compressed by the top rod, causing the spring to be compressed and thus the pressure plate moves toward the cover to open the vent valve, thereby realizing the rapid inflation and deflation of the inflatable product.
[0033] Preferably, the knob assembly includes a knob cap, a rotating rod, a positioning ball, and a positioning spring. The knob assembly is connected to the airway conversion block via the rotating rod. The rotating rod has three sequentially connected recessed positions. The positioning ball is placed in the recessed position and connected to the knob cap via the positioning spring. The recessed position in the middle gradually increases in depth from both sides towards the middle. The recessed positions on both sides are spherical and their size matches that of the positioning ball.
[0034] By using the positioning ball, the entire device can be controlled to be in an inflated, deflated, or stopped state when the knob is turned, thus meeting different user needs and improving the user experience.
[0035] Preferably, a pressure regulating component is also provided on the top of the fixed bracket to monitor the air pressure of the airway during inflation and deflation, so that the air pump can automatically stop inflation and deflation. The pressure regulating component includes a pressure regulating plate, a cap, and a screw. The screw is located in the cap and passes through the bottom of the cap. The distance between the bottom of the screw and the pressure regulating plate can be adjusted by turning the screw to preset the pressure value at which the air pump will automatically stop inflation and deflation.
[0036] The pressure regulating component monitors the air pressure inside the air pump, automatically stopping inflation and deflation. During inflation, the air pressure in the device gradually increases, slowly pushing the pressure regulating plate upward. When the pressure regulating plate abuts against the screw, inflation is complete. At this point, the positioning ball of the knob component slides to the recessed position in the middle, stopping the air pump. During deflation, the air pressure in the device gradually decreases, and the pressure regulating plate slowly moves downward from its abutment against the screw. When the pressure regulating plate separates from the screw to its maximum distance, deflation is complete. At this point, the positioning ball of the knob component slides to the recessed position in the middle, stopping the air pump. This effectively saves energy and ensures the air pump operates smoothly and efficiently.
[0037] Preferably, the housing also includes a wire storage box for storing wires and other small parts, and a cover plate is provided on the top cover, which can be opened to store items into the wire storage box. This application provides a dedicated storage box for storing wires and small parts, making the wires inside the air pump neater and easier to maintain.
[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0039] This invention utilizes multiple air channels to inflate and deflate inflatable products, effectively increasing airflow, reducing inflation / deflation time, lowering energy consumption, and improving the overall efficiency and stability of the air pump device. Furthermore, by employing the interlocking of components such as the knob assembly, air channel switching block, and power switch, the entire air pump structure is made more compact. Controlling only the knob assembly is sufficient to control the inflation, deflation, or shutdown status of the entire device, simplifying operation and improving the user experience.

Detailed Implementation
[0055] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0056] Example 1
[0057] like Figures 1-14 As shown, this embodiment provides a rapid inflation / deflation air pump device, the air pump device comprising:
[0058] Housing 1, with a vent valve 8 on the front side of the housing 1 for connecting the air pump device and the inflatable product;
[0059] Top cover 2, which cooperates with housing 1 to form an internal cavity, and the top cover 2 is provided with a ventilation port for communicating with the outside;
[0060] A fixed bracket 4 is disposed in the internal cavity and includes several vents and several inlets, and a power switch 5 is provided on the top of the fixed bracket 4;
[0061] The exhaust module 6, mounted on the fixed frame, includes a drive assembly 61 and a blower assembly 62, used to increase the airflow at the air inlet and accelerate the gas flow in the device;
[0062] The airway switching module 7 includes a knob assembly 71 and an airway switching block 72. The airway switching block 72 is disposed in the fixed bracket 4 and is connected to the power switch 5 and the ventilation valve 8 respectively. The knob assembly 71 is connected to the top of the airway switching block 72, passes through the top cover 2 and protrudes outside the device. It is used to control the airway switching block 72 to quickly switch the airway openings by operating the knob assembly 71 from outside the device, while simultaneously controlling the opening and closing of the power switch 5 and the ventilation valve 8.
[0063] In this embodiment, by setting several vents and several inlets on the fixed bracket 4, and using the airway conversion module 7 in conjunction with the fixed bracket 4, rapid switching of the vents is achieved. At the same time, the exhaust module 6 is used to increase the airflow at the inlets and accelerate the gas flow rate, thereby enabling rapid inflation and deflation of the inflatable product, effectively reducing inflation and deflation time, reducing energy consumption, and improving the efficiency and stability of the entire air pump device. Furthermore, in this application, the mutual linkage of the knob assembly 71, the airway conversion block, and the power switch 5 is utilized. By turning the knob assembly 71 to move the airway conversion block to a specific position, the vent valve 8 is opened and the power switch 5 is turned on, causing the exhaust assembly to start operating. This effectively improves the working stability of the air pump while achieving inflation and deflation.
[0064] Preferably, such as Figures 5-9 As shown, the fixed bracket 4 includes a bracket body 41 and a back cover 42. The front side of the bracket body 41 is provided with a first vent 43, which is connected to the vent valve 8. The upper rear side of the bracket body 41 is provided with a second vent 44 and a third vent 45, and the lower rear side is provided with a first air inlet 46. The back cover 42 is connected to the rear side of the bracket body 41 to form a receiving cavity. The upper part of the back cover 42 is provided with a sealing surface 47 and an opening 48. The sealing surface 47 is connected to the second vent 44, and the opening 48 is connected to the third vent 45. The lower part of the back cover 42 is provided with a second air inlet 49.
[0065] The cooperation between the support body 41 and the back cover 42 allows gas to flow from multiple different ports when inflating or deflating the inflatable product, thereby effectively increasing the flow rate and reducing the inflation / deflating time.
[0066] Preferably, such as Figure 5 and Figure 6 As shown, the blower assembly 62 is a fan blade and is disposed in the accommodating cavity. Further, in this embodiment, the fan blade can be configured as a double-sided fan blade. By setting a baffle in the middle of the fan blade, the fan blade is divided into left and right parts, which respectively cooperate with the first air inlet 46 and the second air inlet 49 to form two air intake passages.
[0067] like Figure 10 As shown, by setting a baffle in the middle of the fan blade, the airflow can enter the fan blade from the first air inlet 46 and the second air inlet 49 respectively for acceleration. This not only increases the airflow velocity but also the airflow volume, realizing dual-path inflation and deflation, effectively reducing inflation and deflation time and improving work efficiency.
[0068] Preferably,
[0069] like Figure 13 As shown, Figure 13 This is a diagram illustrating an explosion during inflation.
[0070] The ventilation valve 8, the first ventilation port 43, the airway switching block 72, the second ventilation port 44 and the accommodating cavity are connected to form a first airway;
[0071] The air exchange port is connected to the gap formed by the support body 41 and the housing 1 and the first air inlet 46 to form a second air passage;
[0072] The air exchange port is connected to the gap formed by the support body 41 and the housing 1, the third air vent 45, the opening 48, the gap formed by the back cover 42 and the housing 1, and the second air inlet 49 to form a third air passage;
[0073] By twisting the knob assembly 71, the airway switching block 72 is moved to the first airway and connected to the second air port 44. At the same time, the power switch 5 is turned on to start the drive assembly 61 and make the fan blade rotate. The outside gas entering from the air port can enter the fan blade through the second and third airways for airflow acceleration, and then enter the inflatable product through the first airway.
[0074] like Figure 14 As shown, Figure 14 This is a schematic diagram of an explosion in a vented state. During venting...
[0075] The ventilation valve 8, the first ventilation port 43, the airway conversion block, the third ventilation port 45, the opening 48, the gap formed by the back cover 42 and the housing 1, and the second air inlet 49 are connected to form a fourth airway;
[0076] The gap formed by the ventilation valve 8, the support body 41 and the housing 1 and the first air inlet 46 are connected to form a fifth air passage;
[0077] The accommodating cavity, the second vent 44, the gap formed by the support body 41 and the housing 1, and the air exchange port are connected to form a sixth air passage;
[0078] By turning the knob assembly 71, the airway switching block 72 is moved to the fourth airway and connected to the third air port 45. At the same time, the power switch 5 is turned on to start the drive assembly 61 and make the fan blade rotate. The gas discharged from the inflatable product can enter the fan blade through the fourth and fifth airways for airflow acceleration, and then be discharged to the outside through the sixth airway.
[0079] In this application, the inflation and deflation of the inflatable product can be achieved by moving the airway switching block 72 to connect it to the second airway 44 or the third airway 45. Whether it is inflation or deflation, air can be circulated through multiple airways, thereby effectively increasing the airflow and reducing the inflation and deflation time, achieving rapid inflation and deflation of the inflatable product, and effectively reducing power consumption.
[0080] Preferably, such as Figure 8 As shown, the airway switching block 72 has a front-to-back connected structure and is provided with a partition plate 721 inside. The partition plate 721 has an "M" shaped structure and is connected to the ventilation valve 8 to control the opening and closing of the ventilation valve 8. A protrusion 722 is also provided on the top of the airway switching block to cooperate with the power switch 5 to control the power switch 5.
[0081] In the airway conversion block, the partition plate 721 can effectively control the gas to enter the blower assembly 62 from different routes for airflow acceleration, and can also realize the opening and closing of the ventilation valve 8. Furthermore, the top protrusion 722 of the airway conversion block can control the power switch 5 when the airway conversion block moves, thereby making the structure of the entire air pump more compact. Only the control knob assembly 71 is needed to control the inflation, deflation, or stop status of the entire device, simplifying operation and improving the user experience.
[0082] Preferably, such as Figure 7 As shown, the vent valve 8 includes a push rod 81, and a control rod 82 is provided at the bottom of the push rod 81. The top of the control rod 82 is connected to the partition plate 721. When the control rod 82 abuts against the top two sides of the partition plate 721, the partition plate 721 will exert a forward force on the push rod 81 to open the vent valve 8, and the air pump device is in an inflation or deflation state. When the control rod 82 abuts against the middle recess of the partition plate 721, the partition plate 721 will retract the force exerted on the push rod 81 to close the vent valve 8, and the air pump device will stop working.
[0083] By utilizing the abutment between the partition plate 721 and the top rod 81, when the airway conversion block moves to the second air port 44 or the third air port 45, the control rod 82 abuts against the top two sides of the partition plate 721, and the air valve 8 is opened to allow inflation or deflation. When the airway conversion assembly is moved between the second air port 44 and the third air port 45, the control rod 82 abuts against the recess in the middle of the partition plate 721, and the air valve 8 is closed. At this point, the entire device is in a stopped working state, effectively enhancing the stability and reliability of the air pump.
[0084] Preferably, such as Figure 7As shown, the ventilation valve 8 also includes a cover 83, a spring 84, and a pressure plate 85 connected in sequence. The cover 83 has a hole for ventilation. The pressure plate 85 passes through the spring 84 and is connected to the cover 83. A sealing ring 86 is also fitted on the pressure plate 85 to prevent gas leakage. The pressure plate 85 is snapped into the top rod 81. When the exhaust module 6 is working, the spring 84 is compressed under the pressure of the top rod 81, causing the pressure plate 85 to move toward the cover 83, thereby opening the ventilation valve 8.
[0085] In this embodiment, when the vent valve 8 is opened, the pressure plate 85 is compressed by the top rod 81, causing the spring 84 to be compressed, thereby moving the pressure plate 85 toward the cover 83 and opening the vent valve 8, thus realizing the rapid inflation and deflation of the inflatable product.
[0086] Preferably, from Figure 3 , Figure 5 , Figure 6 As can be seen, the knob assembly 71 includes a knob cap 711, a rotating rod 712, a positioning ball 713, and a positioning spring 714. The knob assembly 71 is connected to the airway conversion block via the rotating rod 712. The rotating rod 712 has three sequentially connected recessed positions. The positioning ball 713 is placed in the recessed position and connected to the knob cap 711 via the positioning spring 714. The size of the recessed position in the middle position is close to that of the positioning ball 713. When the positioning ball 713 is in the recessed positions on both sides, the rotating rod 712 drives the airway conversion block to move to the... The second vent 44 or the third vent 45 allows the air pump to be in an inflated or deflated state. The recessed position in the middle gradually increases in depth from both sides towards the middle. When the positioning ball 713 is in the recessed position in the middle, the rotating rod 712 drives the air passage conversion block to move between the second vent 44 and the third vent 45, thereby stopping the air pump. By turning the knob cap 711, the positioning ball 713 can be switched to the recessed position on both sides under the action of the positioning spring 714, thereby switching the working state of the air pump.
[0087] Thus, in this embodiment, by positioning the ball 713, the entire device can be controlled to be in an inflated, deflated, or stopped state when the knob cap 711 is turned, thereby meeting different user needs and improving user experience.
[0088] Preferably, such as Figure 2 , Figure 3 and Figure 5-6As shown, a pressure regulating component 9 is also provided on the top of the fixed bracket 4, which is used to monitor the air pressure of the airway during inflation and deflation so that the air pump can automatically stop inflation and deflation. The pressure regulating component 9 includes a pressure regulating plate 91, a cap 92 and a screw 93. The screw 93 is located in the cap 92 and passes through the bottom of the cap 92. The distance between the bottom of the screw 93 and the pressure regulating plate 91 can be adjusted by turning the screw 93 to preset the pressure value at which the air pump can automatically stop inflation and deflation.
[0089] Thus, the pressure regulating component 9 can monitor the air pressure inside the air pump and automatically stop inflation and deflation. During inflation, the air pressure in the air passage of the device gradually increases, slowly pushing the pressure regulating plate 91 upward. When the pressure regulating plate 91 abuts against the screw 93, inflation is complete. At this time, the positioning ball 713 of the knob component 71 slides to the recessed position in the middle, stopping the air pump. During deflation, the air pressure in the air passage of the device gradually decreases, and the pressure regulating plate 91 slowly moves downward from the state of abutting against the screw 93. When the pressure regulating plate 91 and the screw 93 separate to the maximum distance, deflation is complete. At this time, the positioning ball 713 of the knob component 71 slides to the recessed position in the middle, stopping the air pump. This effectively saves energy and ensures that the air pump can work smoothly and efficiently.
[0090] Preferably, such as Figure 3 As shown, the housing 1 also includes a wire storage box 10 for storing wires and other small parts. A cover plate 101 is also provided on the top cover 2, allowing items to be stored in the wire storage box 10 by opening the cover plate 101. This application incorporates a dedicated storage box to organize wires and small parts, resulting in neater wiring inside the air pump and easier maintenance.
