Description

[0002] The air pump is also called an air pump, an air pump, or an inflator. It works by running a motor and is an inflating tool. The working principle of the air pump: when the motor is running and the air is pumped out, the valve of the communicating vessel is opened by the atmospheric pressure, and the gas enters the cylinder.

DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown, an integrated inflation and deflation air pump device includes a shell 7, a two-way control valve, a control component 8 and a motor 6, wherein the number of the two-way control valves is two, and the two two-way control valves are respectively arranged on both sides of the motor, the two-way control valve and the motor 6 are respectively arranged inside the shell 7, and the control component 8 is connected to the two-way control valve and the motor 6 respectively; the two-way control valve is provided with a first air vent 11, a third air vent 12 and a second air vent 21, the first air vent 11 and the second air vent 21 are not opened at the same time, when the first air vent 11 of one of the two-way control valves is connected with the third air vent 12, the third air vent 12 of the other two-way control valve is connected with the second vent 21, and the first vent 11 and the motor 6 are arranged correspondingly. The control component 8 is used to control the switch of the two-way control valve and the motor 6. The control component 8 executes the inflation command, controls the third vent 12 of one of the two-way control valves (located on the left side of the motor 6) to be connected to the first vent 11, and controls the third vent 12 of another two-way control valve (located on the right side of the motor 6) to be connected to the second vent 21 to inflate the device; the control component 8 executes the deflation command, controls the third vent 12 of one of the two-way control valves (located on the right side of the motor 6) to be connected to the first vent 11, and controls the third vent 12 of another two-way control valve (located on the left side of the motor 6) to be connected to the second vent 21 to deflate the device. When inflation or deflation is required, there is no need to manually replace the inflation pump, which improves work efficiency.

[0022] like Figure 1 and 2As shown, the two-way control valve includes a first valve body 1, a second valve body 2, a first transmission assembly 3 and a second transmission assembly. The interior of the first valve body 1 is connected to the interior of the second valve body 2. The first valve body 1 is provided with the first air vent 11 at one end, and the third air vent 12 is provided at the other end of the first valve body 1. The second valve body 2 is provided with the second air vent 21. The first transmission assembly 3 is movably matched with the first air vent 11 and the second air vent 21 respectively. One end of the second transmission assembly is connected to the first transmission assembly 3, and the other end of the second transmission assembly is movably matched with the third air vent 12. The first transmission assembly 3 includes a screw motor 31, a first sealing gasket 32 ​​and a second sealing gasket 33. The screw motor 31 is installed outside the second valve body 2. The screw shaft 34 of the screw motor 31 enters the second valve body 2. The first sealing gasket 32 ​​and the second sealing gasket 33 are respectively sleeved on the screw shaft 34. The first sealing gasket 32 ​​is movably matched with the first vent 11, and the second sealing gasket 33 is movably matched with the second vent 21. The second transmission assembly includes a transmission rod group 4 and an airtight assembly 5. One end of the transmission rod group 4 is connected to the first sealing gasket 32, and the other end of the transmission rod group 4 is movably abutted against the airtight assembly 5. The airtight assembly 5 is movably matched with the third vent 12. The first sealing gasket 32 ​​and the second sealing gasket 33 are respectively installed on the screw shaft 34 through connecting accessories. One end of the transmission rod group 4 is connected to the connecting accessories, and the other end of the transmission rod group 4 is movably abutted against the airtight assembly 5. The connecting fitting can be a metal gasket, which fixes the first sealing gasket 32 ​​and the second sealing gasket 33 on the screw shaft 34. The first sealing gasket 32 ​​and the second sealing gasket 33 are both made of rubber.

[0023] like Figure 3 As shown, the transmission rod assembly 4 includes a first transmission rod 41 and a second transmission rod 42, the first transmission rod 41 is hinged to the connection fitting, one end of the second transmission rod 42 is hinged to the first transmission rod 41, and the other end of the second transmission rod 42 is movably abutted against the airtight component 5. The screw shaft 34 of the screw motor 31 is set at an angle with the first valve body 1, the diameter of the first sealing gasket 32 ​​is larger than the diameter of the first vent 11, a first limit plate 13 is provided at the connection between the first valve body 1 and the second valve body 2, a second limit plate 14 is provided on the bottom plate of the first valve body 1, the length of the first limit plate 13 is smaller than the length of the second limit plate 14, and the first sealing gasket 32 ​​is movably abutted against the first limit plate 13 and the second limit plate 14 respectively. The screw shaft 34 is tilted relative to the first valve body 1. When the first sealing gasket 32 ​​abuts against the first limit plate 13 and the second limit plate 14, the first sealing gasket 32 ​​and the bottom plate of the first valve body 1 and the first air vent 11 are arranged in a triangle shape to prevent the first air vent 11 from communicating with the second air vent 21.

[0024] like Figure 3As shown, the airtight component 5 includes a sealing plug 51, a connecting rod 52, a limit block 53 and a spring 54. The sealing plug 51 and the spring 54 are respectively slidably arranged on the outer peripheral wall of the connecting rod 52. The limit block 53 is fixedly connected to the connecting rod 52. One end of the spring 54 abuts against the sealing plug 51, and the other end of the spring 54 abuts against the limit block 53. One end of the sealing plug 51 away from the spring 54 movably abuts against the transmission rod group 4. The sealing plug 51 movably cooperates with the third vent 12, and the elastic force value of the spring 54 is less than the pressure value of the airflow. When the screw shaft 34 of the screw motor 31 of one of the two-way control valves (located on the left side of the motor 6) is shortened, the second sealing gasket 33 abuts against the second vent 21 to seal the screw shaft 34, and the screw shaft 34 pushes the second transmission rod 42 to move backward through the first transmission rod 41, so that the second transmission rod 42 abuts against and pushes the sealing plug 51 to move backward, and the spring 54 is compressed to separate the sealing plug 51 from the third vent 12, and the air flows in from the third vent 12 and flows out from the first vent 11, and the screw motor of the other two-way control valve (located on the right side of the motor 6) drives the screw shaft 34 to extend, and the first sealing gasket 32 ​​abuts against the first limit plate 13 and the second limit plate 11 respectively. 4. The second sealing pad 33 is separated from the second vent 21, and the screw shaft 34 drives the first transmission rod 41 and the second transmission rod 42 to move forward. The sealing plug 51 moves forward under the reset force of the spring 54, so that the sealing plug 51 abuts against the third vent 12 to seal, ensuring that the inflatable device does not leak and the gas does not flow back. When the pressure value of the airflow entering the second vent 21 accumulates to a certain level, the airflow pushes the sealing plug 51 and flows out from the third vent 12. Therefore, in the inflated state, the airflow enters from the third vent 12 of the left two-way control valve, flows through the first vent 11 on the left, the second vent 21 on the right, and flows out from the third vent 12 on the right. Similarly, in the deflated state, the airflow enters from the third vent 12 of the right two-way control valve, flows through the first vent 11 on the right, the second vent 21 on the left, and flows out from the third vent 12 on the left. One end of the third vent 12 away from the sealing plug 51 may be provided with a support rod for supporting the second transmission rod 42 , and the second transmission rod 42 is slidably connected to the support rod.

[0025] like Figure 1As shown, the motor 6 includes a first blower 61, a main unit 62 and a second blower 63. The first blower 61 is arranged on one side of the main unit 62, and the second blower 63 is arranged on the other side of the main unit 62. The first vent 11 is connected to the first blower 61 and the second blower 63 respectively. The main unit is a unidirectional motor, and the direction of the blades of the first blower is opposite to that of the blades of the second blower; or, the main unit is a bidirectional motor, and the direction of the blades of the first blower is the same as that of the blades of the second blower. The first blower 61 is located on the left side of the main unit 62, and the second blower 63 is located on the right side of the main unit 62. When inflating, the first vent 11 on the left side is connected to the third vent 12, and the airflow enters the first blower 61. Since the first vent 11 on the right side is closed, the airflow bypasses the second blower 63, enters from the second vent 21, and flows out from the third vent 12 on the right side. When deflated, the first vent 11 on the right is connected to the third vent 12, and the air flows into the second air drum 63. Since the first vent 11 on the left is closed, the air flows around the first air drum 61, enters from the second vent 21, and flows out from the third vent 12 on the left.

[0026] In this embodiment, if Figure 4 As shown, the control assembly 8 includes a first air pressure sensor 81, a second air pressure sensor 82 and a control circuit 84. The first air pressure sensor 81 is used to collect the air pressure value inside the housing 7, and the second air pressure sensor 82 is used to collect the air pressure value inside the device to be inflated and deflated. The control circuit 84 is connected to the first air pressure sensor 81, the second air pressure sensor 82, the two-way control valve, and the motor 6 respectively. The control circuit 84 is used to control the switch of the screw motor 31 and the motor 6. When inflating, the control circuit 84 performs the inflation function, and adjusts the opening / closing of the vents of the two two-way control valves to achieve air pressure saturation of the inflatable device. When the air pressure of the inflatable device is saturated, the airtight air nozzle in the control valve is sealed, the inflatable device does not leak, and the gas does not flow back. When deflated, the control circuit 84 performs the deflation function, and adjusts the opening / closing of the vents of the two two-way control valves to achieve deflation of the deflated device. When the deflation device is finished, the airtight air nozzle in the control valve is sealed, and the gas of the deflated device does not flow back. The control assembly 8 includes a control shell 85 and a display screen 83 . The first air pressure sensor 81 , the second air pressure sensor 82 , the control circuit 84 and the display screen 83 are respectively arranged inside the control shell 85 . The control shell 85 is provided with a through hole that cooperates with the display screen 83 .
