[0030] As mentioned in the background technology, in order to solve the problems in the prior art, this embodiment provides a double-head air pump, comprising:

[0031] A driving member 3, the driving member 3 having two driving ends;

[0032] A first sub-pump body 1 is provided with at least one first air inlet 101 and at least one first air outlet 102;

[0033] The second sub-pump body 2 is provided with at least one second air inlet 201 and at least one second air outlet 202;

[0034] The first sub-pump body 1 and the second sub-pump body 2 are respectively arranged on both sides of the driving member 3 and are transmission connected to different driving ends. The driving member 3 is used to simultaneously drive the first sub-pump body 1 and the second sub-pump body 2, so that the first sub-pump body 1 inhales air from the first air inlet 101 and outputs the first pressurized gas from the first air outlet 102 after pressurization, and also enables the second sub-pump body 2 to inhale air from the second air inlet 201 and output the second pressurized gas from the second air outlet 202 after pressurization. The flow value or pressure value of the first pressurized gas and the second pressurized gas are different.

[0035] like Figure 1 and Figure 2 As shown, the driving member 3 adopts a dual-output shaft motor for providing torque and speed for the first sub-pump body 1 and the second sub-pump body 2. The first sub-pump body 1 and the second sub-pump body 2 are respectively arranged on both sides of the driving member 3. The first sub-pump body 1 is provided with at least one first air inlet 101 and at least one first air outlet 102, and the second sub-pump body 2 is provided with at least one second air inlet 201 and at least one second air outlet 202; when the driving member 3 is started, the first sub-pump body 1 and the second sub-pump body 2 run simultaneously, and the gas enters the first sub-pump body 1 from the first air inlet 101, and outputs the first pressurized gas from the first air outlet 102 after pressurization, and the gas enters the second sub-pump body 2 from the second air inlet 201, and outputs the second pressurized gas from the second air outlet 202 after pressurization. By changing the internal air path structure of the two sub-pump bodies, the first pressurized gas and the second pressurized gas are made to have different states, and the two can have different flow rates or air pressures, and can thus be applied to different scenarios respectively.

[0036] By using a driving member 3 with dual driving ends to simultaneously drive the first sub-pump body 1 and the second sub-pump body 2, a double-headed air pump can be formed. Compared with the traditional air pump with only a single pump body, the double-headed air pump can maximize the use of the kinetic energy of the driving member and improve the energy utilization efficiency. At the same time, the two sub-pump bodies can respectively output pressurized gas in different states, further expanding the scope of application of the double-headed air pump, taking up less space and being more flexible.

[0037] In a preferred embodiment, the volume of the first pressurizing chamber 103 is different from the volume of the second pressurizing chamber 203 .

[0038] As shown in the figure, by changing the volume of the first boost chamber 103 and the volume of the second boost chamber 203, a difference is created between the two, so that the gas pressure or flow output by the first sub-pump body 1 and the second sub-pump body 2 can be different, thereby improving the applicability of the double-head air pump. Furthermore, by respectively adjusting the diameters of the first air outlet 102 and the second air outlet 202, the gas pressure or flow output by the first sub-pump body 1 and the second sub-pump body 2 can be different.

The second base 21 is arranged on the side of the driving member 3 away from the first base 11. A second pump body mechanism is provided between it and the second cover body 22. The second pump body mechanism has at least one second boosting chamber 203 inside. The second air inlet 201, the second boosting chamber 203 and the second air outlet 202 are connected in one direction in sequence. The second pump body mechanism can inhale air from the second air inlet 201 when driven by the driving member 3, and output it from the second air outlet 202 after being pressurized in the second boosting chamber 203.

[0041] like Figure 3As shown, the first base 11, the first cover 12, the second base 21 and the second cover 22 are all shells with open ends. The first base 11 and the second base 21 are fixed on both sides of the driving member 3 as supporting parts of the pump body. The first cover 12 and the second cover 22 are provided with a silencer air duct on the side close to the driving member 3. The silencer air duct is used to eliminate the airflow noise generated when the first sub-pump body 1 and the second sub-pump body 2 are in operation. The first pump body mechanism and the second pump body mechanism have the same structure, both include a torsion shaft 31, and the two torsion shafts 31 are respectively sleeved on the two driving ends of the driving member 3, and the torsion shaft 31 is rotatably connected to the swing plate 32, and the swing plate 32 is approximately a cross-shaped structure, and the side away from the torsion shaft 31 is connected to the boosting component 33, and the outer periphery of the boosting component 33 is sleeved with a fixed seat 34 for fixing and supporting the boosting component 33, and the side of the boosting component 33 away from the swing plate 32 is provided with a gas distribution component. In this embodiment, the boosting component 33 has 4 leather cups 331, and the volume of the leather cup 331 is the volume of the first boosting chamber 103 or the second boosting chamber 203. The gas distribution component is provided with a first one-way valve and a second one-way valve. The first one-way valve of the first sub-pump body 1 connects the first air inlet 101 with the first boosting chamber 103 in one direction, and the second one-way valve connects The first boost chamber 103 and the first air outlet 102, the first one-way valve of the second sub-pump body 2 are unidirectionally connected to the second air inlet 201 and the second boost chamber 203, and the second one-way valve is unidirectionally connected to the second boost chamber 203 and the second air outlet 202; the torsion shaft 31 is driven to rotate by the driving member 3, driving the swing plate 32 to compress / pull up the four leather cups 331 of the boost assembly 33 in sequence along the rotation direction of the torsion shaft 31, so that the first sub-pump body 1 is inhaled from the first air inlet 101, and is pressurized in the first boost chamber 103 and then output from the first air outlet 102, the second sub-pump body 2 is inhaled from the second air inlet 201, and is pressurized in the second boost chamber 203 and then output from the second air outlet 202; the first base 11 and the first cover body 12 can be interlocked through 4 clips 39 to relatively fix the fixing seat 34 and the gas distribution assembly.

[0042] The air distribution assembly includes an upper air distribution layer 36, an air distribution cushion 35 and a lower air distribution layer 37 which are arranged in sequence from the side away from the supercharging assembly 33 to the side close to the supercharging assembly 33. The lower air distribution layer 37 and the upper air distribution layer 36 are used to support the air distribution cushion 35 and assist the air distribution cushion 35 in air distribution. The types of the first one-way valve and the second one-way valve are not particularly limited, and umbrella nails 38 can be used, such as Figure 4 and Figure 5As shown, mounting holes and air inlet holes are correspondingly provided on the lower air distribution layer 37 and the air distribution pad 35. The mounting holes and the air inlet holes are respectively provided in the two pump bodies corresponding to the first boosting chamber 103 and the second boosting chamber 203. The mounting holes are used to set an umbrella nail 38. The umbrella nail 38 includes a nail cap and a nail column. The nail cap is provided on the side of the air distribution component close to the boosting chamber. The air inlet holes can respectively connect the first air inlet 101 and the first boosting chamber 103, as well as the second air inlet 201 and the second boosting chamber 203. When the boosting component 33 contracts, the nail cap is pushed by the gas to cover the air inlet hole, so that the air inlet hole is closed. When the boosting component 33 expands, the gas is affected by the pressure and enters the boosting chamber from the side of the air inlet hole away from the nail cap through the air inlet hole. The above-mentioned umbrella nail 38 can realize the function of one-way communication.

[0043] Further, such as Figure 4 As shown, the first one-way valve and the second one-way valve can also be in the form of a pendulum. The pendulum is arranged on the air distribution cushion 35 and can swing in one direction. The lower air distribution layer 37 and the upper air distribution layer 36 are provided with air inlet holes and air outlet holes at positions corresponding to the pendulum. The pendulum can swing in one direction under the gas pressure in a fixed direction, thereby realizing the function of one-way connection.

Out; the second air inlet path is unidirectionally connected to the second boosting chamber 203 through the first one-way valve, and the second boosting chamber 203 is unidirectionally connected to the second air outlet path through the second one-way valve. When the boosting component 33 of the second sub-pump body 2 expands, the first one-way valve in the second sub-pump body 2 opens, and the second one-way valve closes. The gas enters the second boosting chamber 203 from the second air inlet port 201 through the second air inlet path. When the boosting component 33 of the second sub-pump body 2 contracts, the second one-way valve in the second sub-pump body 2 opens, and the first one-way valve closes. The gas in the second boosting chamber 203 is pressurized and output from the second air outlet port 202 through the second air outlet path.

[0046] In a preferred embodiment, the overall flow direction of the gas in the first sub-pump body 1 is opposite to the overall flow direction of the gas in the second sub-pump body 2 .

[0048] like Figure 5 As shown, the double-head air pump can adopt a structure with air outlet at both ends and air intake in the middle. A first air inlet path is formed between the air distribution component of the first sub-pump body 1 and the first base 11, and a first air outlet path is formed between the air distribution component of the first sub-pump body 1 and the first cover body 12. When the booster component 33 of the first sub-pump body 1 expands, the first one-way valve in the first sub-pump body 1 opens, and the second one-way valve closes. The gas enters the first boosting chamber 103 through the first air inlet path from the first air inlet 101 on the first base 11. When the booster component 33 of the first sub-pump body 1 contracts, the second one-way valve in the first sub-pump body 1 opens, and the first one-way valve closes. The gas in the first boosting chamber 103 is pressurized and then discharged to the first cover body 12 through the first air outlet path. The air is then pumped out of the first outlet 102 of the second sub-pump body 2; a second air inlet path is formed between the air distribution component of the second sub-pump body 2 and the second base 21, and a second air outlet path is formed between the second cover body 22. When the boosting component 33 of the second sub-pump body 2 expands, the first one-way valve in the second sub-pump body 2 opens, and the second one-way valve closes. The gas enters the second boosting chamber 203 through the second air inlet path from the second air inlet 201 on the second base 21. When the boosting component 33 of the second sub-pump body 2 contracts, the second one-way valve in the second sub-pump body 2 opens, and the first one-way valve closes. The gas in the second boosting chamber 203 is pressurized and then output through the second air outlet path to the second air outlet 202 on the second cover body 22.

[0049] like Figure 4As shown, the double-head air pump can also adopt a structure of air intake at both ends and air outlet in the middle. A first air inlet path is formed between the air distribution component of the first sub-pump body 1 and the first cover body 12, and a first air outlet path is formed between the air distribution component of the first sub-pump body 1 and the first base 11. When the booster component 33 of the first sub-pump body 1 expands, the first one-way valve in the first sub-pump body 1 opens, and the second one-way valve closes. The gas enters the first boosting chamber 103 through the first air inlet path from the first air inlet port 101 on the first cover body 12. When the booster component 33 of the first sub-pump body 1 contracts, the second one-way valve in the first sub-pump body 1 opens, and the first one-way valve closes. After being pressurized, the gas in the first boosting chamber 103 is discharged to the first base 11 through the first air outlet path. The air is output from the first air outlet 102; a second air inlet path is formed between the air distribution component of the second sub-pump body 2 and the second cover body 22, and a second air outlet path is formed between the second sub-pump body 2 and the second base 21.

[0050] Furthermore, the above structure can connect the air pipe with the third air outlet between the first air outlet 102 and the second air outlet 202, so that the pressurized gas output from the first air outlet 102 and the second air outlet 202 can be output from the third air outlet together, thereby realizing the parallel connection of the air paths of the first sub-pump body 1 and the second sub-pump body 2.

[0051] In a preferred embodiment, the overall flow direction of the gas in the first sub-pump body 1 is the same as the overall flow direction of the gas in the second sub-pump body 2 .

[0052] In a preferred embodiment, the first air inlet 101 is opened on the first cover 12, the first air outlet 102 is opened on the first base 11, the second air inlet 201 is opened on the second base 21, and the second air outlet 202 is opened on the second cover 22; or the first air inlet 101 is opened on the first base 11, the first air outlet 102 is opened on the first cover 12, the second air inlet 201 is opened on the second cover 22, and the second air outlet 202 is opened on the second base 21.

A first air inlet path is formed between the air distribution component of the first sub-pump body 1 and the first cover body 12, and a first air outlet path is formed between the first sub-pump body 1 and the first base 11. When the booster component 33 of the first sub-pump body 1 expands, the first one-way valve in the first sub-pump body 1 opens and the second one-way valve closes, and gas enters the first booster chamber 103 through the first air inlet port 101 on the first cover body 12 through the first air inlet path. When the booster component 33 of the first sub-pump body 1 contracts, the second one-way valve in the first sub-pump body 1 opens, the first one-way valve closes, and the gas in the first booster chamber 103 After being pressurized, the gas is output from the first air outlet 102 on the first base 11 through the first air outlet route; a second air inlet route is formed between the air distribution component of the second sub-pump body 2 and the second base 21, and a second air outlet route is formed between the second cover body 22.
