Description

Technical Field

[0001] This utility model relates to the field of bidirectional air pump technology, specifically a bidirectional air pump with a built-in anti-leakage device. Background Technology

[0002] A two-way air pump is a device that uses an inflation / deflation motor to expel air from or add air to a closed space. It operates by rotating the motor. One end of the two-way air pump connects to the air valve of an inflatable product via a nozzle connector to inflate the product, while the other end connects to the same valve to deflate it.

[0003] Most existing inflatable products use a valve that opens after the valve connector is inserted, and automatically closes to seal when the connector is removed. When an air pump is used to inflate the product to the specified pressure, the pump stops operating. However, because the valve is open, air inside the product flows backward and is expelled from the pump. This requires manual monitoring during inflation to ensure timely disassembly of the valve connector. Inflating products typically takes several minutes or even longer, resulting in significant waste of manpower. Furthermore, delayed disassembly of the valve connector can cause a substantial drop in pressure, making it difficult to maintain accurate pressure and affecting the product's usability, potentially even posing safety hazards.

[0004] Therefore, there is an urgent need to design a bidirectional air pump with a built-in anti-leakage device. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional air pump with a built-in anti-leakage device.

[0006] A bidirectional air pump with a built-in anti-leakage device includes a sealed housing and a cover. A partition is provided in the middle of both the housing and the cover to form a battery compartment and a charging / discharging compartment. A power supply device is provided in the battery compartment. A charging / discharging device electrically connected to the power supply device is provided in the charging / discharging compartment. An anti-leakage device is provided below the charging / discharging device.

[0007] Furthermore, the inflation / deflation device includes an inflation / deflation port one located at the bottom of the housing and an inflation / deflation port two located at the top of the cover. Both the inflation / deflation port one and the inflation / deflation port two are connected to the inflation / deflation chamber, and an inflation / deflation motor is fixedly installed inside the inflation / deflation chamber.

[0008] Furthermore, the leak-proof device includes a leak-proof bracket, which is disposed in the inflation / deflation chamber above the first inflation / deflation port and is fixedly connected to the bottom of the housing. A valve stem mounting hole is provided in the middle of the leak-proof bracket, and multiple air passage holes are provided on the leak-proof bracket outside the valve stem mounting hole. A valve stem is fixedly disposed in the valve stem mounting hole, and a one-way umbrella-shaped air valve is disposed below the leak-proof bracket and fixedly connected to the valve stem. The one-way umbrella-shaped air valve is disposed between the leak-proof bracket and the first inflation / deflation port and is sealed to the multiple air passage holes.

[0009] Furthermore, the power supply device includes a rechargeable battery fixedly installed in the battery compartment. The rechargeable battery is electrically connected to the charging and discharging motor. A charging port electrically connected to the rechargeable battery is provided on one side of the cover. A button hole is provided on the top of the cover, and a button switch electrically connected to the charging and discharging motor is provided in the button hole.

[0010] Furthermore, an indicator light electrically connected to the rechargeable battery is provided on the top of the cover.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention incorporates a leak-proof device within the inflation / deflation chamber. This device seals the chamber immediately when the inflation / deflation motor stops, preventing air from flowing back into the inflatable product and leaking out. Furthermore, this invention eliminates the need for dedicated personnel during inflation, and the pressure drop in the inflatable product will not be significantly reduced even without timely disassembly of the air nozzle connector. This ensures the accuracy of the inflatable product's pressure and guarantees its safe use. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described as follows:

[0024] A bidirectional air pump with a built-in anti-leakage device includes a sealed housing 1 and a cover 2. Both the housing 1 and the cover 2 are provided with a sealed partition 3 in the middle. The partition 3 divides the internal space of the housing 1 and the cover 2 into a battery compartment 4 and a charging / discharging compartment 5. A power supply device is provided in the battery compartment 4. A charging / discharging device electrically connected to the power supply device is provided in the charging / discharging compartment 5. An anti-leakage device is provided below the charging / discharging device.

[0025] In this embodiment, the power supply device provides the power required for the operation of the inflation / deflation device.

[0026] During inflation, connect the air nozzle connector 19 to the inflation end of the inflation / deflation device, insert the air nozzle connector 19 into the air nozzle of the inflatable product, and the air nozzle connector 19 will open the air nozzle valve to connect the components. The inflation / deflation device is started by controlling the power supply device. The anti-leakage device deforms under the action of airflow and no longer seals, and the inflation / deflation device inflates the inflatable product.

[0027] When inflation stops, the inflation / deflation device ceases operation, and the air inside the inflatable product flows in the reverse direction. This reverse airflow restores the leak-proof device to its original state and seals it, preventing airflow from entering the inflation / deflation chamber 5 and causing leakage. This invention eliminates the need for dedicated personnel to monitor inflation, and the air pressure in the inflatable product will not significantly decrease even if the air nozzle connector 19 is not disassembled in a timely manner, ensuring the accuracy of the air pressure and guaranteeing the safe use of the inflatable product.

[0028] During deflation, the air nozzle connector 19 is connected to the deflation end of the inflation / deflation device. The air nozzle connector 19 is then inserted into the air nozzle of the inflatable product. The air nozzle connector 19 opens the air nozzle valve, allowing airflow within the inflatable product to flow in reverse into the inflation / deflation chamber 5. The leak-proof device deforms under the influence of the airflow and ceases to seal, allowing airflow to escape from the inflation end of the inflation / deflation device. Preferably, controlling the inflation / deflation device via a power supply device can accelerate the deflation efficiency of the inflatable product.

[0029] The inflation / deflation device includes an inflation / deflation port 12 located at the bottom of the housing 1 and an inflation / deflation port 23 located at the top of the cover 2. Both the inflation / deflation port 12 and the inflation / deflation port 23 are connected to the inflation / deflation chamber 5. An inflation / deflation motor 11 is fixedly installed inside the inflation / deflation chamber 5.

[0030] In this embodiment, during inflation, the air nozzle connector 19 is connected to the inflation / deflation interface 12. During deflation, the air nozzle connector 19 is connected to the inflation / deflation interface 13. The inflation / deflation motor 11 can be started by controlling the power supply device to perform inflation or deflation operations on the inflatable product.

[0031] The leak-proof device includes a leak-proof bracket 14, which is installed in the inflation / deflation chamber 5 above the inflation / deflation port 12 and is fixedly connected to the bottom of the housing 1. A valve stem mounting hole 15 is provided in the middle of the leak-proof bracket 14. Multiple air passage holes 16 are provided on the leak-proof bracket 14 outside the valve stem mounting hole 15. A valve stem 17 is fixedly installed in the valve stem mounting hole 15. A one-way umbrella-shaped air valve 18 is provided below the leak-proof bracket 14 and is fixedly connected to the valve stem 17. The one-way umbrella-shaped air valve 18 is located between the leak-proof bracket 14 and the inflation / deflation port 12 and is sealed to the multiple air passage holes 16.

[0032] In this embodiment, the appendix Figure 5-7 The arrows shown indicate the direction of airflow during inflation and deflation.

[0033] During inflation, connect the air nozzle connector 19 to the inflation / deflation interface 12. Insert the air nozzle connector 19 into the air nozzle of the inflatable product, and the air nozzle connector 19 will open the air nozzle valve to connect it. The inflation / deflation motor 11 is started by controlling the power supply device. The airflow generated by the inflation / deflation motor 11 passes through the air passage 16 and blows the one-way umbrella-shaped air valve 18, causing it to deform and no longer seal the air passage 16. The airflow enters the inflatable product through the air nozzle connector 19 and the air nozzle, inflating the product.

[0034] When inflation stops, the inflation / deflation motor 11 stops working, and the air inside the inflatable product will flow in reverse. The reverse airflow passes through the air nozzle and air nozzle connector 19 and blows the one-way umbrella-shaped air valve 18 to restore its original shape. The one-way umbrella-shaped air valve 18 is attached to the bottom of the leak-proof bracket 14 and seals the air passage 16, so the airflow cannot enter the inflation / deflation chamber 5 and leak.

[0035] During deflation, the air nozzle connector 19 is connected to the inflation / deflation interface 13, and the air nozzle connector 19 is inserted into the air nozzle of the inflatable product. The air nozzle connector 19 opens the air nozzle valve to establish connection. The airflow inside the inflatable product flows in reverse, passing through the air nozzle and air nozzle connector 19 to the inflation / deflation chamber 5. After passing through the air passage 16, the airflow blows the one-way umbrella-shaped air valve 18, causing it to deform and no longer seal the air passage 16. The airflow is then discharged from the inflation / deflation interface 12. Preferably, starting the inflation / deflation motor 11 via a power supply device can accelerate the deflation efficiency of the inflatable product.

[0036] The power supply device includes a rechargeable battery 6 fixedly installed in the battery compartment 4. The rechargeable battery 6 is electrically connected to the charging and discharging motor 11. A charging port 7 electrically connected to the rechargeable battery 6 is provided on one side of the cover 2. A button hole 8 is provided on the top of the cover 2. A button switch 9 electrically connected to the charging and discharging motor 11 is provided in the button hole 8. An indicator light 10 electrically connected to the rechargeable battery 6 is provided on the top of the cover 2.

[0037] In this embodiment, the rechargeable battery 6 provides the power required for the operation of the air charging / discharging motor 11. The start and stop of the air charging / discharging motor 11 can be controlled by the push-button switch 9. The rechargeable battery 6 can be charged using a charger or power bank through the charging port 7. Preferably, the real-time power level of the rechargeable battery 6 can be displayed by the indicator light 10.
