Description

Technical Field

[0001] The present application belongs to the technical field of inflation equipment, and specifically relates to an inflation pump. Background Art

[0002] The pump body can quickly inflate tires, outdoor inflatable products, recreational inflatable products, etc., making it the most widely used vehicle-mounted tool. Cars are usually also equipped with an on-board emergency power supply, which is a portable charger that integrates power supply and charging functions. It can be used to start the car in an emergency when the car is out of power or cannot be started for other reasons. At the same time, it can charge or provide standby power for digital devices such as mobile phones anytime and anywhere.

[0003] Usually people will bring both the pump body and the emergency power supply in the car when traveling outdoors, but the space in the trunk of the car is limited, and placing both the pump body and the emergency power supply at the same time will take up a lot of space, causing inconvenience to self-driving travel. Summary of the invention

[0004] The purpose of this application is to provide an air pump that integrates components such as a pump body, a battery, and a circuit board into a box, which greatly reduces the space occupied, is easy to carry and store, and solves the space occupation problem caused by carrying the traditional pump body and emergency power supply separately.

[0005] The technical solution adopted by the present application to solve the above-mentioned technical problems is: an air pump is proposed, including: a box body, a pump body, a battery, and a circuit board are arranged in the box body, a display screen and an indicator light are arranged on the box body, the pump body, the circuit board, the display screen and the indicator light are all electrically connected to the battery, the pump body, the battery, the display screen and the indicator light are all electrically connected to the circuit board, a first air inlet is arranged on the box body corresponding to the pump body, an inflation port and an air inlet are arranged on the pump body, the inflation port and the air inlet are both connected to the first air inlet, a power supply interface and a wiring port electrically connected to the battery are arranged on the box body, a control button assembly is also arranged on the box body, and the control button assembly is electrically connected to the circuit board.

[0006] Through the above technical features, when the user needs to use the pump body to inflate the tire or other inflatable products, the control button assembly sends a command to the circuit board. After receiving the command, the circuit board will start the pump body connected to the battery. The battery provides power to the pump body, so that the pump body starts working. The air inlet of the pump body is connected to the outside air through the first air inlet hole, and the outside air is sucked into the pump body. Then, through the mechanical action of the pump body, the air is compressed and discharged through the inflation port. Since the inflation port is connected to the external connection pipe or the inflatable product, the compressed air will enter the tire or the inflatable product to achieve rapid inflation. At the same time, when the car battery feed is damaged or the car cannot be started at low temperature, the power supply interface is used instead of the battery to start the car in an emergency; when electronic devices such as mobile phones, computers, Bluetooth headsets, digital cameras, etc. need to be charged, the wiring port can be used to provide power for digital devices such as mobile phones. In addition, when the car breaks down at night and needs to be repaired or asked for help, the indicator light can provide functions such as strong light long-range shooting, flashing warning, and SOS distress signal lights. Moreover, the display screen and indicator light can display the working status of the pump and the battery power and other information in real time, which makes it easy for users to understand the working status of the equipment, improves the convenience and safety of use, and the switch of the pump and the inflation pressure and other parameters can be easily controlled through the control button assembly, which is simple and convenient to operate.

[0007] Therefore, the air pump of the present application integrates the pump body, battery, circuit board and other components into a box, which greatly reduces the space occupied, is easy to carry and store, and solves the space occupation problem caused by carrying the traditional pump body and emergency power supply separately.

[0008] Preferably, the pump body comprises a motor, a transmission member, a piston, and a cylinder body, wherein the motor is arranged in the box body and electrically connected to the battery, the transmission member is rotatably connected to the output shaft of the motor, the piston is connected to one end of the transmission member, and the piston is slidably connected to the cylinder body, and the cylinder body is provided with an air charging port and an air inlet, and the air charging port and the air inlet are respectively provided with a first one-way valve and a second one-way valve;

[0009] When the motor drives the piston to move away from the inflation port, the first one-way valve is closed and the second one-way valve is opened to complete the suction; when the motor drives the piston to move toward the inflation port, the first one-way valve is opened and the second one-way valve is closed, and the piston compresses the gas to complete the inflation.

[0010] Through the above technical features, when inhaling, when the motor drives the piston to move to the side away from the inflation port, the gas pressure in the cylinder body decreases, causing the second one-way valve to open, allowing external air to enter the cylinder body through the air inlet. At the same time, due to the decrease in pressure in the cylinder body, the first one-way valve is closed to prevent gas from flowing out of the inflation port; when inflating, when the motor drives the piston to move to the side close to the inflation port, the gas in the cylinder body is compressed, causing the first one-way valve to open, allowing the compressed gas to be discharged through the inflation port. At the same time, due to the increase in pressure in the cylinder body, the second one-way valve is closed to prevent external air from entering the cylinder body again. By driving the piston to reciprocate through the motor, an efficient intake-inflation cycle is realized, the inflation speed is fast, and the work efficiency is improved. The one-way flow of gas during the intake and inflation process is ensured by setting a one-way valve, avoiding gas backflow and improving the stability of the system.

[0011] Preferably, a plurality of second air inlet holes are arranged around the first air inlet hole and are distributed in a spiral shape along the circumferential direction.

[0012] Through the above technical features, the spirally distributed second air inlet holes increase the air inlet area, so that more external air can be inhaled in the same time, thereby improving the air intake efficiency of the air pump. At the same time, due to the improvement of the air intake efficiency, the cylinder can be filled with compressed gas more quickly, thereby increasing the inflation speed and shortening the inflation time.

[0013] Preferably, a fan is rotatably connected to one end of the motor away from the transmission member, the fan is rotatably connected to an output shaft of the motor, and a heat dissipation hole is provided on the box body corresponding to the fan.

[0014] Through the above technical features, since the fan is directly connected to the motor output shaft, it can ensure that the fan speed matches the motor speed, making the heat dissipation more timely and effective. When the motor is running, the heat generated can be quickly dissipated to the external environment through the heat dissipation holes through the rotation of the fan, effectively reducing the motor temperature and preventing overheating.

[0015] Preferably, an air pressure sensor is provided in the pump body, and the air pressure sensor is electrically connected to the circuit board.

[0016] Through the above technical features, when the air pump is working, the motor drives the piston to reciprocate in the cylinder to compress or release the gas. In this process, the air pressure sensor will monitor the air pressure changes in the cylinder in real time. The air pressure sensor senses the strength of the air pressure, converts it into electrical signals, and transmits these signals to the circuit board. After receiving these signals, the circuit board will perform corresponding processing, such as displaying them on the display screen, controlling the working status of the air pump, etc. Through the electrical connection between the air pressure sensor and the circuit board, the air pump can be automatically controlled. When the air pressure reaches the preset value, the circuit board can automatically shut down the air pump to avoid safety problems caused by over-inflation.

[0017] Preferably, a storage cavity is provided on one side of the box body, an inflation hose and a connector are placed in the storage cavity, the connector includes several different types of connectors, and a cover plate is also provided on the outside of the storage cavity.

[0018] Through the above technical features, when the user needs to use the air pump, he can open the cover of the storage cavity, select the appropriate inflation hose and connector, and then connect them to the main part of the air pump to perform the inflation operation. By setting up a special storage cavity, the inflation hose and connector can be neatly placed in the box, avoiding the problems of clutter and loss, and also making it easier for users to carry and move the air pump. In addition, a variety of different types of connectors are placed in the storage cavity, which can meet the inflation needs of inflatable equipment or items of different specifications and types. Users do not need to purchase or carry other adapters, which improves the versatility and practicality of the air pump.

[0019] Preferably, the wiring port includes a charging and discharging interface and a USB interface electrically connected to the battery.

[0020] Through the above technical features, the charging and discharging interface makes the charging and discharging operations of the battery simple and direct. The user only needs to connect the charger or power-consuming device to the corresponding interface to realize the charging or discharging function without additional conversion equipment or operation steps; the USB interface is a widely used standard interface with high versatility. It supports charging and data transmission of multiple devices, providing great convenience for users, especially for modern electronic devices, many of which are equipped with USB interfaces, which makes charging through the USB interface possible.

[0021] Preferably, the indicator light includes a headlight and a side light, the headlight is a high beam light, and the side light is a flood light.

[0022] Through the above technical features, during use, when the car breaks down at night and needs repair or help, the headlights can be used to provide strong long-range light, flashing warning, SOS distress signal and other functions. When soft and wide-area lighting is required, the side lights can be used for lighting. Therefore, the indicator light of this application can provide efficient, uniform and multifunctional lighting effects to meet the lighting needs of different occasions.

[0023] In summary, this application has the following beneficial effects:

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present application and combined with the accompanying drawings to further describe the technical solution of the present application, but the present application is not limited to these embodiments.

[0034] like Figure 1 , Figure 2As shown, the present application discloses an air pump, comprising: a box body 1, a display screen 6 and a control button assembly 14 are provided at the upper end of the box body 1, a pump body 2, a battery 3, and a circuit board 4 are provided in the box body 1, the pump body 2, the circuit board 4, the display screen 6, and the control button assembly 14 are electrically connected to the battery 3, and the battery 3 provides power for them, and the pump body 2, the battery 3, the display screen 6, and the control button assembly 14 are all electrically connected to the circuit board 4, and the operation of each component is controlled by the circuit board 4.

[0035] When the user needs to use the pump body 2 to inflate a tire or other inflatable product, the user sends an instruction to the circuit board 4 through the control button assembly 14. After receiving the instruction, the circuit board 4 will start the pump body 2 connected to the battery 3. The battery 3 provides power to the pump body 2, so that the pump body 2 starts working. The pump body 2 sucks external air into the pump body 2, and then, through the mechanical action of the pump body 2, the air is compressed and discharged. Since the pump body 2 is connected to the external connecting pipe or the inflatable product, the compressed air will enter the tire or inflatable product to achieve a quick inflation function.

[0036] The box body 1 is provided with a power supply interface 12 electrically connected to the battery 3. When the car battery 3 is damaged or the car cannot be started due to low temperature, the power supply interface 12 replaces the battery to start the car in an emergency, thereby realizing the function of emergency power supply.

[0037] The display screen 6 is used to display the working status of the pump body 2 and the power level of the battery 3 in real time, so that the user can understand the working status of the equipment and improve the convenience and safety of use.

[0038] The control button assembly 14 can easily control parameters such as the switch of the inflation pump and the inflation pressure, and the operation is simple and convenient.

[0039] In order to facilitate the charging and discharging of the battery 3 , a connection port 13 electrically connected to the battery 3 is provided on the box body 1 . The connection port 13 includes a charging and discharging interface 131 and a USB interface 132 electrically connected to the battery 3 , respectively.

[0040] The charge and discharge interface 131 makes the charging and discharging operations of the battery 3 simple and direct. The user only needs to connect the charger or power-consuming device to the corresponding interface to realize the charging or discharging function without the need for additional conversion equipment or operating steps; the USB interface 132 is a widely used standard interface with high versatility. It supports charging and data transmission of multiple devices, providing great convenience for users, especially for modern electronic devices, many of which are equipped with a USB interface 132, which makes charging through the USB interface 132 possible.

[0041] like Figure 3As shown, in order to facilitate the lighting function, the box body 1 of the present application is provided with an indicator light 5, and the indicator light 5 includes a headlamp 51 and a sidelamp 52 arranged on two connected sides of the box body 1. In the present application, the headlamp 51 is a long-range lamp, and the sidelamp 52 is a floodlight. When the car breaks down at night and needs maintenance or help, the headlamp 51 can be used to provide functions such as strong long-range light, flashing warning, and SOS distress signal. When soft and wide-area lighting is required, the sidelamp 52 can be used for lighting, so the indicator light 5 of the present application can provide multi-functional lighting effects to meet the lighting needs of different occasions.

[0042] like Figure 3 , Figure 4 As shown, the pump body 2 of the present application includes a motor 23, a transmission member 24, a piston 25, and a cylinder body 26. The motor 23 is arranged in the box body 1 and is electrically connected to the battery 3. The transmission member 24 is rotatably connected to the output shaft of the motor 23. The piston 25 is connected to one end of the transmission member 24. The piston 25 is slidably connected in the cylinder body 26. The cylinder body 26 is provided with an inflation port 21 and an air inlet 22.

[0043] The box body 1 is provided with a first air inlet 11 corresponding to the pump body 2 , the inflation port 21 and the air inlet 22 are both connected to the first air inlet 11 , and a plurality of second air inlet holes 15 are provided around the first air inlet 11 and are distributed in a spiral shape along the circumference.

[0044] In the present application, a first one-way valve and a second one-way valve (not shown in the figure) are respectively provided at the inflation port 21 and the air inlet 22 .

[0045] During operation, when inhaling, the motor 23 drives the piston 25 to move toward the side away from the inflation port 21, and the gas pressure in the cylinder 26 decreases, causing the second one-way valve to open, allowing external air to enter the cylinder 26 through the air inlet 22. At the same time, due to the decrease in pressure in the cylinder 26, the first one-way valve is closed to prevent gas from flowing out of the inflation port 21; when inflating, when the motor 23 drives the piston 25 to move toward the side close to the inflation port 21, the gas in the cylinder 26 is compressed, causing the first one-way valve to open, allowing the compressed gas to be discharged through the inflation port 21. At the same time, due to the increase in pressure in the cylinder 26, the second one-way valve is closed to prevent external air from entering the cylinder 26 again.

[0046] Therefore, the motor 23 drives the piston 25 to perform reciprocating motion, thereby realizing an efficient suction-inflation cycle, fast inflation speed, and improved work efficiency. A one-way valve is provided to ensure one-way flow of gas during the suction and inflation process, thereby avoiding gas backflow and improving system stability.

[0047] In order to effectively reduce the temperature of the motor 23 and prevent the motor 23 from overheating in the present application, a fan 27 is rotatably connected to the end of the motor 23 away from the transmission member 24. The fan 27 is rotatably connected to the output shaft of the motor 23, and a heat dissipation hole 16 is provided on the box body 1 corresponding to the fan 27. The heat is quickly dissipated to the external environment through the heat dissipation hole 16 when the fan 27 rotates.

[0048] In order to monitor the air pressure changes in the cylinder 26 in real time, an air pressure sensor (not shown in the figure) is provided in the pump body 2 in the present application, and the air pressure sensor is electrically connected to the circuit board 4. The air pressure sensor senses the strength of the air pressure, converts it into electrical signals, and transmits these signals to the circuit board 4. After receiving these signals, the circuit board 4 will perform corresponding processing, such as displaying them on the display screen 6, controlling the working state of the air pump, etc. Through the electrical connection between the air pressure sensor and the circuit board 4, the air pump can be automatically controlled. When the air pressure reaches the preset value, the circuit board 4 can automatically shut down the air pump to avoid safety problems caused by over-inflation.

[0049] like Figure 5 As shown, a storage cavity 17 is provided on one side of the box body 1, and an inflatable hose 171 and a connector 172 are placed in the storage cavity 17. The connector 172 includes several different types of connectors 172, and a cover plate 173 is also provided on the outside of the storage cavity 17. When the user needs to use the air pump, the cover plate 173 of the storage cavity 17 can be opened, and a suitable inflatable hose 171 and connector 172 can be selected from them, and then connected to the main part of the air pump to perform the inflating operation. In addition, a plurality of different types of connectors 172 are placed in the storage cavity 17, and these connectors 172 can meet the inflatable needs of inflatable devices or items of different specifications and types. The user does not need to purchase or carry other adapters, which improves the versatility and practicality of the air pump.

[0050] Working principle: When the user needs to use the pump body 2 to inflate a tire or other inflatable product, the control button assembly 14 sends a command to the circuit board 4. After receiving the command, the circuit board 4 will start the pump body 2 connected to the battery 3. The battery 3 provides power to the pump body 2, so that the pump body 2 starts working. The air inlet 22 of the pump body 2 is connected to the outside air through the first air inlet hole 11, and the outside air is sucked into the pump body 2. Then, through the mechanical action of the pump body 2, the air is compressed and discharged through the inflation port 21. Since the inflation port 21 is connected to the external connecting pipe or the inflatable product, the compressed air will enter the tire or the inflatable product to achieve rapid inflation.

[0051] When the car battery 3 is damaged or the car cannot be started due to low temperature, the power supply interface 12 can be used to replace the battery for emergency starting of the car; when electronic devices such as mobile phones, computers, Bluetooth headsets, digital cameras, etc. need to be charged, the connection port 13 can be used to provide power for digital devices such as mobile phones.

[0052] In addition, when the car breaks down at night and needs repair or help, the indicator light 5 can provide functions such as strong light long-range shooting, flashing warning, SOS distress signal light, etc.

[0053] Therefore, the air pump of the present application integrates the pump body 2, battery 3, circuit board 4 and other components into a box body 1, which greatly reduces the space occupation, is easy to carry and store, and solves the space occupation problem caused by carrying the traditional pump body 2 and emergency power supply separately.

[0054] The specific embodiments described herein are merely examples of the present application. A person skilled in the art of the present application may make various modifications or additions to the specific embodiments described or replace them in a similar manner without departing from the scope defined in the present application.
