Description

Technical Field

[0001] The present invention relates to the technical field of air pumps for inflating and deflation of air, and more particularly to an air pump device for fast inflating and deflation of air. Background Art

[0002] At present, air pumps in the prior art are used in conjunction with inflatable products (such as air mattresses, inflatable toys, tires, etc.) in many applications. Traditional air pumps transmit airflow through a single path. When inflating, air enters the inflatable product through the air pump, and when deflated, the air is discharged through the same path. However, this single airway design may lead to low efficiency of inflation and deflation, especially in situations where rapid inflation or deflation is required, which consumes a long time. For many inflatable products, shortening the time of inflation and deflation is very important, which not only affects the user experience, but also affects the working efficiency of the air pump. Traditional air pumps may be restricted by exhaust pressure when inflating, resulting in a slow inflation process; when deflated, the flow rate of the exhaust airflow may also be limited, resulting in a long deflation time. Therefore, when the air pump inflates and deflates the inflatable product, more electricity is consumed, which is not in line with the energy-saving and environmental protection trend of industrial products. Summary of the invention

[0003] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide an air pump device for rapid inflation and deflation, which is used to increase the air flow rate, reduce the inflation and deflation time, and reduce the electrical energy.

[0010] In the present invention, a plurality of vents and a plurality of air inlets are arranged on the fixed bracket, and an airway conversion module is used in cooperation with the fixed bracket to realize rapid switching of the vents. At the same time, an exhaust module is used to increase the air inlet flow and accelerate the gas flow rate, thereby realizing rapid inflation and deflation of the inflatable product, effectively reducing the inflation and deflation time, reducing energy consumption, and improving the efficiency and stability of the entire air pump device; and in the present application, the mutual linkage of the knob assembly, the airway conversion block and the power switch is also utilized, and the knob assembly is twisted to move the airway conversion block to a specific position, and the ventilation valve is opened while the power switch is turned on, so that the exhaust assembly starts to operate, and the inflation and deflation are realized while the working stability of the air pump is effectively improved.

[0011] Preferably, the fixed bracket includes a bracket body and a back cover, the front side of the bracket body is provided with a first air vent, and the first air vent is connected to the ventilation valve; the upper rear side of the bracket body is provided with a second air vent and a third air 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 and forms an accommodating cavity, the upper part of the back cover is provided with a closed surface and an opening, the closed surface is communicated with the second air vent, and the opening is connected with the third vent; and the lower part of the back cover is provided with a second air inlet.

[0012] Through the cooperation between the bracket body and the back cover, gas can flow from multiple different ports when the inflatable product is inflated or deflated, thereby effectively increasing the flow rate and reducing the inflation and deflation time.

[0013] Preferably, the air blowing assembly is a fan blade, and is disposed in the accommodating cavity, and cooperates with the first air inlet and the second air inlet to form a plurality of air inlet passages.

[0014] The fan blades can be used to allow the air flow to enter the blower assembly from the first air inlet and the second air inlet respectively for acceleration, which can not only increase the air flow velocity but also increase the air flow rate, realize dual-path inflation and deflation, effectively reduce the inflation and deflation time, and improve 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 chamber are connected to form a first airway;

[0018] The ventilation port is connected with the gap formed by the bracket body and the shell and the first air inlet to form a second air passage;

[0019] The ventilation port, the gap formed by the bracket body and the shell, the third ventilation port, the opening, the gap formed by the back cover and the shell, and the second air inlet are connected to form a third air passage;

[0020] By twisting the knob assembly to move the airway switching block to the first airway and connect it to the second vent, the vent valve is opened and the power switch is turned on to start the driving assembly to rotate the fan blade, and the external air entering from the ventilation port can enter the fan blade through the second airway and the third airway to accelerate the airflow, and then enter the inflatable product through the first airway;

[0021] When deflation is performed,

[0022] The vent valve, the first vent, the airway conversion block, the third vent, the opening, the gap formed by the back cover and the shell, and the second air inlet are connected to form a fourth airway;

[0023] The vent valve, the gap formed by the bracket body and the shell, 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 bracket body and the shell, and the ventilation port are connected to form a sixth airway;

[0025] The airway switching block is moved to the fourth airway and connected to the third vent by twisting the knob assembly, and the vent valve is opened while the power switch is turned on to start the drive assembly to rotate the fan blade. The gas exhausted from the inflatable product can enter the fan blade through the fourth airway and the fifth airway to accelerate the airflow, and then be discharged to the outside through the sixth airway.

[0026] In the present application, the inflation and deflation of the inflatable product can be achieved by moving the airway switching block to connect it to the second vent or the third vent, and ventilation can be performed through multiple airways regardless of whether it is air intake, inflation or deflation, thereby effectively increasing the airflow rate, reducing the inflation and deflation time, achieving rapid inflation and deflation of the inflatable product, and effectively reducing electrical energy.

[0027] Preferably, the airway switching block is a front-to-back connected structure, and a partition plate is provided inside it. The partition plate is 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] In the airway conversion block, the partition plate provided can effectively control the gas to enter the blowing assembly from different routes for airflow acceleration, and can also realize the opening and closing of the ventilation valve. The top protrusion of the airway conversion block can also control the power switch when the airway conversion block moves, thereby making the structure of the entire air pump more compact. Only the knob assembly needs to be controlled to control the inflation, deflation or stop state of the entire device, thereby simplifying the operation and improving the user experience.

[0029] Preferably, the ventilation valve includes a push rod, a control rod is provided at the bottom of the push rod, and the top of the control rod is connected to the partition plate. When the control rod abuts against the two sides of the top of the partition plate, the partition plate will give the push rod a forward force to open the ventilation valve, and the air pump device is in an inflated or deflated state; when the control rod abuts against the middle recess of the partition plate, the partition plate retracts the forward force on the push rod to close the ventilation valve, and the air pump device is in a stopped working state.

[0030] By utilizing the abutment between the partition plate and the top rod, when the airway conversion block moves to the second vent or the third vent, the control rod abuts against the two sides of the top of the partition plate, and the ventilation valve will be opened for inflation or deflation. When the airway conversion assembly is moved between the second vent or the third vent, the control rod abuts against the middle recess of the partition plate, and the ventilation valve is closed. Here the entire device is in a stopped working state, effectively enhancing the stability and reliability of the air pump.

[0031] Preferably, the ventilation valve also includes a cover body, a spring and a pressure plate which are connected in sequence, the cover body is provided with a hole for ventilation, the pressure plate is connected to the cover body through the spring, and a sealing ring is also provided on the pressure plate to prevent gas leakage; the pressure plate is connected to the push rod by a clamping connection, and when the exhaust module is working, under the squeezing of the push rod, the spring is compressed to move the pressure plate toward the cover body so that the ventilation valve opens.

[0032] In the present application, when the vent valve is opened, the pressure plate compresses the spring under the pressure of the push rod, so that the pressure plate moves toward the cover body to open the vent valve, thereby realizing rapid inflation and deflation of the inflatable product.

[0033] Preferably, the knob assembly includes a knob cap, a rotary rod, a positioning ball and a positioning spring. The knob assembly is connected to the airway switching block via the rotary rod. The rotary rod is provided with three recessed positions connected in sequence. The positioning ball is placed in the recessed position and is connected to the knob cap via the positioning spring. The recessed position located in the middle position gradually increases in depth from both sides to the middle; the recessed positions located on both sides are spherical recessed shapes, and their size fits the positioning ball.

[0034] By positioning the positioning ball, the entire device can be controlled to be in an inflated, deflated or stopped working state when twisting the knob cap, meeting the different needs of users and improving the user experience.

[0035] Preferably, a pressure regulating assembly is also provided on the top of the fixed bracket, which is used to monitor the air pressure of the airway airflow during inflation and deflation so that the air pump automatically stops inflating and deflation; the pressure regulating assembly includes a pressure regulating plate, a buckle cap and a screw, and the screw is arranged in the buckle cap and passes through the bottom of the buckle cap. The distance between the bottom of the screw and the pressure regulating plate can be adjusted by twisting the screw to preset the pressure value at which the air pump automatically stops inflating and deflation.

[0036] Therefore, the air pressure in the air pump can be monitored by the pressure regulating assembly to automatically stop inflation and deflation. During inflation, the airway pressure in the device gradually increases, slowly pushing the pressure regulating plate upward. When the pressure regulating plate abuts against the screw, it indicates that inflation is completed. At this time, the positioning ball of the knob assembly slides to the recessed position in the middle position to stop the air pump device; during deflation, the airway pressure in the device gradually decreases, and the pressure regulating plate slowly moves downward from the abutting state with the screw. When the pressure regulating plate and the screw are separated to the maximum distance, it indicates that deflation is completed. At this time, the positioning ball of the knob assembly slides to the recessed position in the middle position to stop the air pump device; thereby effectively saving electric energy and ensuring that the air pump can work smoothly and efficiently.

[0037] Preferably, a wire storage box is provided inside the housing to store wires and other small parts, and a cover is provided on the top cover, and items can be stored in the wire storage box by opening the cover. In the present application, a special storage box is provided to store wires and some small parts, so that the wires inside the air pump are neater and easier to inspect.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] The present invention realizes the inflation and deflation of inflatable products by setting multiple airways, effectively increases the airflow rate, reduces the inflation and deflation time, reduces energy consumption, and improves the working efficiency and stability of the entire air pump device. In addition, by utilizing the mutual linkage of components such as the knob assembly, the airway conversion block, and the power switch, the structure of the entire air pump is made more compact. Only the knob assembly needs to be controlled to control the inflation, deflation, or stop working state of the entire device, which simplifies the operation and improves the user experience.

[0064] Preferably, if Figure 5-Figure 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 air vent 43, and the first air vent 43 is connected to the ventilation valve 8; the upper rear side of the bracket body 41 is provided with a second air vent 44 and a third air 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 and forms a accommodating cavity, and the upper part of the back cover 42 is provided with a closed surface 47 and an opening 48, the closed surface 47 is connected to the second air vent 44, and the opening 48 is connected to the third air vent 45; the lower part of the back cover 42 is provided with a second air inlet 49.

[0065] Through the cooperation between the support body 41 and the back cover 42, gas can flow from multiple different ports when the inflatable product is inflated or deflated, thereby effectively increasing the flow rate and reducing the inflation and deflation time.

[0066] Preferably, if Figure 5 and Figure 6 As shown, the blowing assembly 62 is a fan blade and is arranged in the accommodating cavity. Furthermore, in this embodiment, the fan blade can be arranged as a double-sided fan blade. By setting a baffle in the middle of the fan blade, the fan blade is divided into two left and right parts, and cooperates with the first air inlet 46 and the second air inlet 49 to form two air inlet passages.

[0068] Preferably,

[0069] like Fig.13 As shown, Fig.13 This is a schematic diagram of the explosion in the inflated state. When inflating,

[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 ventilation port is connected to the gap formed by the bracket body 41 and the shell 1 and the first air inlet 46 to form a second air passage;

[0072] The ventilation port is connected with the gap formed by the bracket body 41 and the shell 1, the third ventilation port 45, the opening 48, the gap formed by the back cover 42 and the shell 1, and the second air inlet 49 to form a third air passage;

[0073] By twisting the knob assembly 71 to move the airway switching block 72 to the first airway and connect it to the second vent 44, the vent valve 8 is opened and the power switch 5 is turned on to start the driving assembly 61 to rotate the fan blade, and the external air entering from the ventilation port can enter the fan blade through the second airway and the third airway to accelerate the airflow, and then enter the inflatable product through the first airway;

[0074] like Fig.14 As shown, Fig.14 This is a schematic diagram of the explosion in the deflated state. When deflated,

[0077] The accommodating cavity, the second vent 44, the gap formed by the bracket body 41 and the shell 1, and the ventilation port are connected to form a sixth airway;

[0078] The airway switching block 72 is moved to the fourth airway and connected to the third vent 45 by twisting the knob assembly 71, and the vent valve 8 is opened while the power switch 5 is turned on to start the drive assembly 61 to rotate the fan blade. The gas exhausted from the inflatable product can enter the fan blade through the fourth airway and the fifth airway to accelerate the airflow, and then be discharged to the outside through the sixth airway.

[0079] In the present 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 vent 44 or the third vent 45, and whether it is air intake, inflation or deflation, ventilation can be performed through multiple airways, thereby effectively increasing the airflow rate, reducing the inflation and deflation time, achieving rapid inflation and deflation of the inflatable product, and effectively reducing electrical energy.

[0080] Preferably, if Figure 8 As shown, the airway switching block 72 is a front-to-back connected structure, and a partition plate 721 is provided inside thereof. The partition plate 721 is an "M"-shaped structure, and is connected to the ventilation valve 8 for controlling the opening and closing of the ventilation valve 8. A protrusion 722 is also provided on the top of the airway switching block for cooperating with the power switch 5 to control the power switch 5.

[0081] In the airway conversion block, the partition plate 721 provided can effectively control the gas to separate and enter the blowing assembly 62 from different routes for airflow acceleration, and can also realize the opening and closing of the ventilation valve 8. The top protrusion 722 of the airway conversion block can also control the power switch 5 when the airway conversion block moves, thereby making the structure of the entire air pump more compact. Only the knob assembly 71 needs to be controlled to control the inflation, deflation or stop state of the entire device, thereby simplifying the operation and improving the user experience.

[0082] Preferably, if Figure 7 As shown, the ventilation 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 airway conversion assembly is moved between the second air port 44 or the third air port 45, the control rod 82 abuts against the middle recess of the partition plate 721, and the ventilation valve 8 is closed. Here the entire device is in a stopped working state, effectively enhancing the stability and reliability of the air pump.

[0084] Preferably, if Figure 7As shown, the ventilation valve 8 also includes a cover body 83, a spring 84 and a pressure plate 85 which are connected in sequence. The cover body 83 is provided with a hole for ventilation. The pressure plate 85 is connected to the cover body 83 through the spring 84. A sealing ring 86 is also sleeved on the pressure plate 85 to prevent gas leakage. The pressure plate 85 is connected to the push rod 81 by snap-fitting. When the exhaust module 6 is working, under the squeezing of the push rod 81, the spring 84 is compressed to move the pressure plate 85 toward the cover body 83, thereby opening the ventilation valve 8.

[0085] In this embodiment, when the vent valve 8 is opened, the pressure plate 85 compresses the spring 84 under the pressure of the push rod 81, so that the pressure plate 85 moves toward the cover body 83 to open the vent valve 8, thereby realizing rapid inflation and deflation of the inflatable product.

[0086] Preferably, from Figure 3 , Figure 5 , Figure 6 It can be seen that the knob assembly 71 includes a knob cap 711, a rotary rod 712, a positioning ball 713 and a positioning spring 714. The knob assembly 71 is connected to the airway switching block via the rotary rod 712. The rotary rod 712 is provided with three recessed positions connected in sequence. The positioning ball 713 is placed in the recessed position and is connected to the knob cap 711 via the positioning spring 714. The recessed position located in the middle position is sized to fit the positioning ball 713. When the positioning ball 713 is located at the recessed positions on both sides, the rotary rod 712 drives the airway switching block to move to the The second air vent 44 or the third air vent 45, so that the air pump device is in an inflated or deflated state; the recessed position at the middle position gradually increases in depth from both sides to the middle, and when the positioning ball 713 is located in the recessed position at the middle position, the rotary rod 712 drives the airway conversion block to move between the second air vent 44 and the third air vent 45, so that the air pump device is in a stopped working state, and by twisting the knob cap 711, the positioning ball 713 can be switched to the recessed position on both sides driven by the positioning spring 714, thereby switching the working state of the air pump device.

[0087] Therefore, in this embodiment, by positioning the positioning ball 713, the entire device can be controlled to be in an inflated, deflated or stopped working state when the knob cap 711 is twisted, thereby meeting different needs of users and improving user experience.

[0088] Preferably, if Figure 2 , Figure 3 and Figure 5-6As shown, a pressure regulating assembly 9 is also provided on the top of the fixed bracket 4, which is used to monitor the air pressure of the airway airflow during inflation and deflation so that the air pump automatically stops inflating and deflation; the pressure regulating assembly 9 includes a pressure regulating plate 91, a buckle cap 92 and a screw 93, and the screw 93 is set in the buckle cap 92 and passes through the bottom of the buckle cap 92. The distance between the bottom of the screw 93 and the pressure regulating plate 91 can be adjusted by twisting the screw 93 to preset the pressure value at which the air pump automatically stops inflating and deflation.

[0089] Therefore, the air pressure in the air pump can be monitored by the pressure regulating assembly 9 to automatically stop inflation and deflation. During inflation, the airway pressure in the device gradually increases, slowly pushing the pressure regulating plate 91 upward, and when the pressure regulating plate 91 abuts against the screw 93, it indicates that inflation is completed. At this time, the positioning ball 713 of the knob assembly 71 slides to the recessed position in the middle position to stop the air pump device; during deflation, the airway pressure in the device gradually decreases, and the pressure regulating plate 91 slowly moves downward from the abutting state with the screw 93. When the pressure regulating plate 91 and the screw 93 are separated to the maximum distance, it indicates that deflation is completed. At this time, the positioning ball 713 of the knob assembly 71 slides to the recessed position in the middle position to stop the air pump device; thereby effectively saving electric energy and ensuring that the air pump can work smoothly and efficiently.

[0090] Preferably, if Figure 3 As shown, the housing 1 is further provided with a wire storage box 10 for storing wires and other small parts, and the top cover 2 is further provided with a cover plate 101, and items can be stored in the wire storage box 10 by opening the cover plate 101. In the present application, a special storage box is provided to store wires and some small parts, so that the wires inside the air pump are neater and easier to inspect.
