Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the priority of application number CN202311152297.9 filed with the China Patent Office on September 7, 2023 and entitled “An integrated high-pressure and high-flow air pump”. Technical Field

[0003] The present application relates to the field of air pumps, and in particular to an air pump integrating high pressure and high flow. Background Art

[0004] The prior art has two motors, one for driving a high-flow pump and the other for driving a high-pressure pump, which are connected together through a structure, resulting in high cost and low inflation efficiency. Only one of the two motors is working, and the utilization rate is not high.

[0005] For example, a high-pressure and high-flow inflatable core with a publication number of CN218760360U uses a double air intake manifold to connect both the fan air supply device and the piston air supply device. The fan air supply device is used to output a large flow of gas to the double air intake manifold, and the piston air supply device is used to output high-pressure gas to the double air intake manifold, and under the action of the first one-way valve and the second one-way valve, cross-wind is avoided; if the air pressure value of the inflatable product is low, the fan air supply device is started to output a large flow of gas to the double air intake manifold to fill a large amount of gas and improve the inflation efficiency. When the air pressure value of the inflatable product is high and the inflation volume of the fan air supply device is greatly reduced, the fan air supply device is turned off, and the piston air supply device is started to output high-pressure gas to the double air intake manifold until the expected high air pressure value is reached. It can be seen from the above content that only one of the fan air supply device and the piston air supply device can work, and only one of the corresponding two motors can be in operation, resulting in low inflation efficiency and low utilization rate.

[0006] The solution of the present invention is to improve the existing air pump in view of the above-mentioned problems. Summary of the invention

[0007] In order to overcome the deficiencies in the prior art, the present invention provides an integrated high-pressure and high-flow air pump to solve the problems of low inflation efficiency, only one of the two motors working and low utilization rate in the prior art air pump.

[0008] In order to achieve the above-mentioned invention object, the technical solution adopted to solve the technical problem is as follows:

[0009] An integrated high-pressure and high-flow air pump includes an air pump housing, an air outlet, an air inlet, a high-flow pump, a motor, a high-flow air duct, a gear set, a high-pressure pump, a one-way valve and a two-in-one air flow channel, wherein:

[0010] The high-flow pump is connected to the high-flow air duct;

[0011] The motor is placed inside the air pump housing and built into the high-flow air duct, and is connected to the air inlet;

[0012] One end of the motor output shaft is connected to the high-flow pump, and the other end of the motor output shaft is connected to the high-pressure pump through a gear set;

The motor drives the gear set to decelerate, and passes through the high-pressure pump, the two-in-one air flow channel and the air outlet in sequence to provide high-pressure inflation to the inflated object.

[0016] Furthermore, it also includes a pressure relief valve, which is arranged on the high-flow pump. When the internal pressure of the inflated object reaches a certain value, the one-way valve is closed so that the compressed air generated by the high-flow pump is discharged into the interior of the inflation pump through the pressure relief valve to dissipate heat for the inflation pump.

[0017] Furthermore, the high-pressure pump includes a cylinder and a piston and a connecting rod arranged inside the cylinder, one end of the connecting rod is connected to the gear set, and the other end of the connecting rod is connected to the piston, which is used to drive the connecting rod to reciprocate in the cylinder through the rotation of the gear set.

[0018] Furthermore, the two-in-one airflow channel includes a high-flow channel and a high-pressure channel. The high-flow channel is sleeved on the periphery of the high-pressure channel. The high-flow channel is unidirectionally connected to the high-flow air duct through a one-way valve, and the high-pressure channel is connected to the high-pressure pump through a cylinder:

[0019] When the high-flow pump and the high-pressure pump are working, the motor starts, the air is sucked in through the air inlet, and the air flow passes through the high-flow pump, the high-flow air duct, the one-way valve, the high-flow channel and the air outlet in sequence to provide high-flow inflation to the inflated object. The motor drives the gear set to decelerate, and passes through the high-pressure pump, the high-pressure channel and the air outlet in sequence to provide high-pressure inflation to the inflated object.

[0020] Preferably, the high-flow channel and the high-pressure channel have the same center, and the two are arranged in concentric circles.

[0021] Furthermore, it also includes a high-flow pump connector, a first high-flow air duct connector and a first sealing ring. The high-flow pump connector is connected to the first high-flow air duct connector, and the first sealing ring is sealed between the high-flow pump connector and the first high-flow air duct connector.

[0022] Furthermore, it also includes a second connecting piece of the high-flow air duct, a first connecting piece of the two-in-one airflow channel and a second sealing ring. The second connecting piece of the high-flow air duct is connected to the first connecting piece of the two-in-one airflow channel, and the two sealing rings are sealed between the second connecting piece of the high-flow air duct and the first connecting piece of the two-in-one airflow channel.

[0023] Furthermore, it also includes an air outlet connector, a second connector of the two-in-one airflow channel and a third sealing ring. The air outlet connector is connected to the second connector of the two-in-one airflow channel, and the third sealing ring is sealed between the air outlet connector and the second connector of the two-in-one airflow channel.

[0024] Furthermore, it also includes a cylinder connector, a third connector of the two-in-one airflow channel and a fourth sealing ring. The cylinder connector is connected to the third connector of the two-in-one airflow channel, and the fourth sealing ring is sealed between the cylinder connector and the third connector of the two-in-one airflow channel.

[0025] Preferably, the air inlet and the air outlet are located on the same side of the air pump.

[0026] Optionally, a connecting portion is provided at the air outlet, and the two-in-one airflow channel is connected to the inflated object via the connecting portion.

[0027] Optionally, the connecting portion is a connecting thread arranged at the air outlet.

[0028] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0029] 1. The present invention is an integrated high-pressure and high-flow air pump. The high pressure and high flow are in the same channel. The high pressure and high flow are driven by the same motor and can be quickly switched. One motor can be used for two purposes, thereby realizing the universal inflation function of the product, saving cost and space, greatly improving the inflation efficiency, and being able to quickly inflate paddle boards, tires, tents, etc. At the same time, it solves the problem of long inflation time and inconvenient user operation of traditional inflatables.

[0030] 2. The present invention is an integrated high-pressure and high-flow air pump. Since only one motor is used, the internal structure of the air pump is more compact, the design is more reasonable, the cost is lower, and the overall volume is smaller. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] like Figure 1-3 As shown, this embodiment discloses an integrated high-pressure and high-flow air pump, including an air pump housing (not shown), an air outlet 1, an air inlet 2, a high-flow pump 3, a motor 4, a high-flow air duct 5, a gear set 6, a high-pressure pump 7, a one-way valve 8 and a two-in-one air flow channel 9, wherein:

[0060] The high-flow pump 3 and the high-flow air duct 5 are connected by screws or buckles;

[0061] The motor 4 is horizontally placed at the lower part of the air pump housing and built into the high-flow air duct 5 and communicated with the air inlet 2;

[0062] One end of the output shaft of the motor 4 is connected to the high-flow pump 3, and the other end of the output shaft of the motor 4 is connected to the high-pressure pump 7 through the gear set 6. For example, the first output shaft of the motor 4 is connected to the high-flow pump 3, and the second output shaft is connected to the high-pressure pump 7 through the gear set 6;

[0063] The high-pressure pump 7 is vertically placed at the lower part of the air pump housing and is connected to the two-in-one air flow channel 9;

[0064] The high-flow air duct 5 is connected to the two-in-one air flow channel 9 through a one-way valve 8;

[0065] When the high-flow pump 3 and the high-pressure pump 7 work at the same time, the motor 4 starts, and the air inlet 2 sucks in air. The airflow passes through the high-flow pump 3, the high-flow air duct 5, the one-way valve 8, the two-in-one airflow channel 9 and the air outlet 1 in sequence to provide high-flow inflation to the inflated object. At the same time, the motor 4 drives the gear set 6 to decelerate, and passes through the high-pressure pump 7, the two-in-one airflow channel 9 and the air outlet 1 in sequence to provide high-pressure inflation to the inflated object.

[0066] Furthermore, the air pump further includes a pressure relief valve 10, which is disposed at the lower part of the high-flow pump 3 and is used to close the one-way valve 8 when the internal pressure of the inflated object reaches a certain value, so that the compressed air generated by the high-flow pump 3 is discharged into the air pump through the pressure relief valve 10 to dissipate heat for the air pump. Figure 2 In the embodiment, the pressure relief valve 10 is arranged on the side wall of the high flow air duct 5. Further, as Figure 2 In the figure, the pressure relief valve 10 is located next to the gear set 6 and the high-pressure pump 7, so that the compressed air generated by the high-flow pump 3 can dissipate heat for the gear set 6 and the high-pressure pump 7 after being discharged through the pressure relief valve 10.

[0067] In this embodiment, the high-pressure pump 7 includes a cylinder (not shown) and a piston (not shown) and a connecting rod (not shown) arranged inside the cylinder. One end of the connecting rod is connected to the gear set 6, and the other end is connected to the piston, which is used to drive the connecting rod to reciprocate in the cylinder through the rotation of the gear set 6.

[0068] Furthermore, the two-in-one airflow channel 9 includes a high-flow channel 11 and a high-pressure channel 12, the high-flow channel 11 is sleeved on the periphery of the high-pressure channel 12, the high-flow channel 11 is unidirectionally connected to the high-flow air duct 5 through the one-way valve 8, and the high-pressure channel 12 is connected to the high-pressure pump 7 through the cylinder. Preferably, the center of the high-flow channel 11 and the high-pressure channel 12 is the same, and the two are arranged in concentric circles, which greatly reduces the space and makes the structure more compact. In actual operation, it is only necessary to sleeve the high-pressure channel 12 on the periphery of the high-flow channel 11.

[0069] In a preferred embodiment, the inflation pump also includes a high-flow pump connector 13, a high-flow air duct first connector 14 and a first sealing ring (not shown in the figure). The high-flow pump connector 13 and the high-flow air duct first connector 14 are connected by screws or snaps. The first sealing ring is airtightly connected between the high-flow pump connector 13 and the high-flow air duct first connector 14, which can well ensure the air tightness between the high-flow pump 3 and the high-flow air duct 5.

[0070] Secondly, the air pump also includes a second connecting piece 15 of the high-flow air duct, a first connecting piece 16 of the two-in-one airflow channel and a second sealing ring (not shown in the figure). The second connecting piece 15 of the high-flow air duct and the first connecting piece 16 of the two-in-one airflow channel are connected by screws or snaps. The second sealing ring is airtightly connected between the second connecting piece 15 of the high-flow air duct and the first connecting piece 16 of the two-in-one airflow channel, which can well ensure the air tightness between the high-flow air duct 5 and the two-in-one airflow channel 9.

[0071] Furthermore, the air pump also includes an air outlet connector 17, a two-in-one airflow channel second connector 18 and a third sealing ring (not shown). The air outlet connector 17 and the two-in-one airflow channel second connector 18 are connected by screws or snaps. The third sealing ring is airtightly connected between the air outlet connector 17 and the two-in-one airflow channel second connector 18, which can well ensure the air tightness between the air outlet 1 and the two-in-one airflow channel 9.

[0072] Furthermore, the air pump also includes a cylinder connector 19, a two-in-one airflow channel third connector 20 and a fourth sealing ring (not shown). The cylinder connector 19 and the two-in-one airflow channel third connector 20 are connected by screws or snaps. The fourth sealing ring is airtightly connected between the cylinder connector 19 and the two-in-one airflow channel third connector 20, which can well ensure the air tightness between the cylinder and the two-in-one airflow channel 9.

[0073] Preferably, the air inlet 2 and the air outlet 1 are located on the same side of the air pump, which makes it more convenient for users to operate. Preferably, the air inlet 2 and the air outlet 1 are arranged vertically or left and right. In this embodiment, since the shell of the inflatable treasure is a vertical structure, the air inlet 2 and the air outlet 1 are arranged vertically, and the product structure is more compact and slim.

[0074] In some possible implementations, a connection portion is provided at the air outlet so that the connection portion is relatively exposed, which facilitates its connection with the inflatable object, avoids the need to first use an adapter to lead out the non-exposed connection portion and then connect it to the inflatable object through the adapter, and helps to improve the convenience of use for users. Figure 2 As shown, a connection portion may be provided at the left port of the air outlet.

[0075] It can be understood that when the air outlet is connected to the inflated object through the connecting portion, the connecting portion can be connected to the inflation nozzle of the inflated object so that the inflation nozzle is directly connected to the air outlet.

[0076] In actual settings, the connecting part can be set to a universal structure, which is convenient for the connecting part to adapt to the inflation nozzle of universal specifications and realize a stable connection between the two, so that the air pump can be connected to most inflated objects, thus avoiding the use of an adapter to connect the inflation nozzle.

[0077] In some possible embodiments, the connection portion may be a connection thread provided at the air outlet, and the connection thread may be a universal thread, so that it can be screwed together with the universal thread provided on the inflation nozzle to achieve a stable connection. It should be understood that the connection thread at the air outlet may be an internal thread or an external thread, and the present application does not impose any specific limitation thereto.

[0078] Specific working principle:

[0079] When the high-flow pump 3 and the high-pressure pump 7 work at the same time, the motor 4 starts, and the air inlet 2 sucks in air. The airflow passes through the high-flow pump 3, the high-flow air duct 5 in the two-in-one airflow channel 9, the one-way valve 8, the high-flow channel 11 and the air outlet 1 in sequence to provide high-flow inflation to the inflated object. At the same time, the motor 4 drives the gear set 6 to decelerate, and passes through the high-pressure pump 7, the high-pressure channel 12 in the two-in-one airflow channel 9 and the air outlet 1 in sequence to provide high-pressure inflation to the inflated object.

[0080] When the internal pressure of the inflated object reaches a certain value, the one-way valve 8 is closed so that the compressed air generated by the high-flow pump 3 is discharged into the interior of the inflation pump through the pressure relief valve 10 to dissipate heat for the inflation pump.

[0081] When inflation is performed in high-pressure mode alone, the motor 4 starts, air is sucked in through the air inlet 2, and the airflow passes through the one-way valve 8, the high-flow channel 11 and the air outlet 1 in sequence. The port of the high-flow channel 11 is closed, and the airflow is reversed to dissipate heat for the high-pressure channel 12. At the same time, the motor 4 drives the gear set 6 to slow down, and passes through the high-pressure pump 7, the high-pressure channel 12 and the air outlet 1 in sequence, and finally enters the inflated object to provide high pressure.

[0082] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
