Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conveying equipment, in particular to an air pump suitable for outdoor inflatable products. Background Art
[0002] An air pump is an inflatable tool. Its working principle is that when the motor is running, the air pressure opens the valve of the connecting device, allowing air to enter the cylinder. When the air is inflated, the air pressure in the cylinder closes the valve, allowing air to enter the object being inflated. Air pumps are widely used to inflate cars, motorcycles, bicycles, balls, rubber boats, and other items.
[0003] In the existing technology, the air pump is usually a low-pressure air pump with a large flow rate, while the high-pressure air pump has a small flow rate. The use scenarios of a single type of air pump are relatively limited. In addition, some existing technical structures use an integrated high-pressure and low-pressure air pump. For example, one motor is used to drive the high and low-pressure air pumps to work at the same time. This method not only increases functional loss, but may also cause motor overload. There are also devices that work separately for high and low-pressure air pumps (a low-pressure air pump is used when the air pressure is low, and a high-pressure compression pump is used when high air pressure is required), but the high-pressure pump (compression pump module) is usually detachable, resulting in poor air tightness. At the same time, the air pump requires the air pump motor to reverse to perform the vacuum function, which increases the complexity of the operation. Utility Model Content
[0004] In order to solve the problems in the prior art of insufficient integration of the high-pressure and low-pressure parts of the air pump, resulting in poor air tightness, high energy consumption, and complicated air pumping operations, the utility model provides an air pump suitable for outdoor inflatable products.
[0005] The technical solution adopted in this utility model is:
[0006] An air pump suitable for outdoor inflatable products, comprising an air pump module and a compression pump module, wherein the air pump module and the compression pump module are connected to the same air blowing housing, and an air outlet is provided on the air blowing housing;
[0007] The air pump module is provided with an air inlet, which is connected to the air outlet through an air pump one-way valve, and an air pump wheel is provided in the air pump module;
[0008] Wherein, a compression pump one-way valve is provided on the compression pump module, a piston rod compression mechanism is provided in the compression pump module, and an air outlet end of the piston rod compression mechanism is communicated with the air outlet.
[0009] Furthermore, the air pump module includes an air suction shell and an air pump motor connected to the air suction shell, the air pump wheel is arranged in the air suction shell, and the motor shaft of the air pump motor is connected to the air pump wheel.
[0010] Furthermore, the compression pump module includes a compression housing and a compression motor connected to the compression housing, and the compression motor is connected to the piston rod compression mechanism through a reduction transmission mechanism.
[0011] Furthermore, the piston rod compression mechanism includes a cylinder connected between the compression shell and the blowing shell and a piston rod arranged in the cylinder. A piston sealing ring is slidably connected between the piston rod and the inner wall of the cylinder, and the end of the piston rod is connected to the reduction transmission mechanism.
[0012] Furthermore, the reduction transmission mechanism includes a first gear and a second gear, and the first gear and the second gear are arranged in the compression housing;
[0013] The second gear is connected to the motor shaft of the compression motor, the second gear is meshed with the first gear, the first gear is connected to the eccentric shaft, and the eccentric shaft is connected to the end of the piston rod.
[0014] The beneficial effects of the utility model are:
[0015] The air pump of the present invention comprises a high-pressure output compression pump module and a low-pressure output air pump module. The two modules are integrally connected and have the same air outlet, which has a stronger air tightness than the air pumps of the prior art. During inflation, the air pump can start the air pumping of the two modules separately according to the pressure requirement of the pumped air without affecting each other, thereby avoiding excessive motor load and excessive unnecessary functional loss. The high-pressure output compression pump module compresses air through a piston rod compression mechanism, and a high-torque motor and a reduction mechanism can be used to achieve compression to obtain a higher pressure, while the air pump module delivers air through an air pump wheel, which can obtain a larger air intake volume and can be applied to more scenarios with different needs. The air inlet and the air charging port provided in the air pump of the present invention can realize the exhaust function without reversing the motor. When exhaust is required, the pipes connected to the air inlet and the air outlet are removed and exchanged and then connected to change the air inlet and outlet directions of the external device, thereby realizing the function of exhausting air even when the motor direction remains unchanged. Compared with the prior art, this structure further enhances the air tightness and convenience of the air pump. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0022] Example 1
[0023] Please refer to Figure 1-Figure 3 The utility model is an air pump suitable for outdoor inflatable products, including an air pump module and a compression pump module. The air pump module and the compression pump module are connected to the same blowing shell 6, and the blowing shell 6 is provided with an air outlet 15; the air pump module is provided with an air inlet 16, and the air inlet 16 is connected to the air outlet 15 through an air pump one-way valve 7, and an air pump wheel 14 is provided in the air pump module; the compression pump module is provided with a compression pump one-way valve 8, and a piston rod compression mechanism is provided in the compression pump module, and the air outlet end of the piston rod compression mechanism is connected to the air outlet 15. When the air pump is working, when low-pressure inflation is required, the driving mechanism of the air pump module is started to drive the air pump wheel 14 to rotate, and air enters from the air inlet 16 of the air pump module, passes through the air pump one-way valve 7, and is output from the air outlet 15 to achieve pumping. When high-pressure inflation is required, the driving mechanism of the compression pump module is started to drive the piston rod compression mechanism to start moving, and air enters from the compression housing 4 of the compression pump module, passes through the compression pump one-way valve 8 and enters the cylinder 5 of the piston rod compression mechanism. The air is compressed by the movement of the piston rod 10, and the compressed high-pressure air is then pumped out through the air outlet 15 to achieve inflation. The air pump of the present invention also has an air suction function, and it can be achieved without turning the motor over. Specifically, when it is necessary to pump air, the pipes connected to the air inlet 16 and the air outlet 15 are removed and exchanged with each other and then connected, so as to change the air inlet and outlet direction of the external device, and achieve the function of pumping air even when the motor direction remains unchanged.
[0024] The air pump of the present invention has a compression pump module with high-pressure output and an air pump module with low-pressure output. The two modules are integrally connected and have the same air outlet 15, which is more airtight than the air pumps in the prior art. When inflating, the air pump can start the pumping of the two modules separately according to the pressure requirement of the pumping air without affecting each other, avoiding excessive motor load and excessive unnecessary functional loss. The compression pump module with high-pressure output compresses the air through a piston rod compression mechanism, and a large torque motor and a reduction mechanism can be used to achieve compression to obtain a higher pressure, while the air pump module delivers air through an air pump wheel 14, which can obtain a larger air intake volume and can be applied to more scenarios with different needs. The air inlet 16 and the inflation port set in the air pump of the present invention can realize the exhaust function without reversing the motor. Compared with the prior art, this structure further enhances the airtightness and convenience of the air pump.
[0025] Example 2
[0026] This example is based on Example 1, please refer to Figure 2 、 Figure 3 The air pump module includes an air intake housing 1 and an air pump motor 2 connected to the air intake housing 1. An air pump wheel 14 is disposed within the air intake housing 1, and the motor shaft of the air pump motor 2 is connected to the air pump wheel 14. The air pump can drive the air pump wheel 14 connected thereto to rotate by rotating the motor shaft of the air pump motor 2, thereby transporting air through the air pump wheel 14. In this mode, the air pump outputs a large air flow, lower pressure, and lower power consumption. To ensure the overall air tightness of the air pump, a sealing ring and other components can also be provided at the connection between the air pump motor 2 and the air intake housing 1 to avoid air leakage, prevent pressure drop and loss of air flow, thereby improving the working efficiency of the equipment.
[0027] Example 3
[0028] This example is based on Example 1, please refer to Figure 2 、 Figure 3 The compression pump module includes a compression housing 4 and a compression motor 3 connected to the compression housing 4. The compression motor 3 is connected to the piston rod compression mechanism via a reduction gear mechanism. When the compression motor 3 is started, it transmits power to the reduction gear mechanism. After the reduction gear mechanism has a set reduction ratio, the power is transmitted to the piston rod compression mechanism, causing the piston rod 10 to perform reciprocating piston motion. The air is compressed and pumped out through a cycle of intake and exhaust, which can quickly output higher pressure air and achieve high-pressure inflation.
[0029] As a preferred embodiment, the piston rod compression mechanism includes a cylinder 5 disposed on a compression housing 4 and a piston rod 10 disposed within the cylinder 5. A piston seal 9 is slidably connected between the piston rod 10 and the inner wall of the cylinder 5, and the end of the piston rod 10 is connected to the reduction transmission mechanism. The piston seal 9 ensures the airtightness of the piston rod 10 during the air compression process. The connection between the piston rod 10 and the reduction transmission mechanism can be achieved through an eccentric wheel mechanism, an eccentric shaft 11 mechanism, a cam mechanism, and other mechanisms that can convert rotational motion into linear reciprocating motion. The specific structural setting can be reasonably selected and set by those skilled in the art based on the parameter requirements, structural distribution, etc. of the air pump design.
[0030] As a preferred embodiment, the reduction transmission mechanism includes a first gear 12 and a second gear 13, which are disposed within the compression housing 4. The second gear 13 is connected to the motor shaft of the compression motor 3, and the second gear 13 meshes with the first gear 12. The first gear 12 is connected to an eccentric shaft 11, which is connected to the end of the piston rod 10. This structure uses a gear reduction mechanism to reduce the power output by the compression motor 3. This allows the use of a high-speed, high-torque motor with a smaller reduction ratio to achieve greater torque output and faster inflation speeds. Compared to conventional air pumps, this achieves greater pressure and faster inflation.
[0031] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
