Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to a portable air pump. Background Technology

[0002] An air pump, also known as an air compressor or tire inflator, is an inflation tool that works by using a motor. Its working principle is as follows: when the motor is running, the valve of the pump is opened by atmospheric pressure, allowing air to enter the cylinder; when inflating a tire, the valve is closed by the air pressure inside the cylinder, allowing air to enter the tire. This design utilizes the principle of atmospheric pressure to achieve the inflation function.

[0003] Air pumps are widely used for various inflation needs, including car tires, motorcycles, bicycles, balls, inflatable boats, and more. Their efficient working principle and portable design allow users to easily inflate various devices, ensuring their proper functioning. Especially for car tires, air pumps not only ensure proper tire pressure and improve driving safety, but also solve problems such as temporary tire blowouts in emergencies, providing drivers with greater safety assurance.

[0004] Air pumps have a wide range of applications, and the most common air pumps on the market are mainly divided into electric air pumps and manual air pumps. However, both electric and manual air pumps are relatively large or long in size and have a heavy overall weight. Because they take up a lot of space, they are not convenient to carry. Therefore, a portable air pump needs to be designed. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a portable air pump to more accurately resolve the issue of pressure inability to adjust during use of the nasal irrigator.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a portable air pump, including a pump body. One side of the inner wall of the pump body is provided with an operating area for mechanical operation, and the other side of the inner wall of the pump body is provided with a storage area for storing items. An air pumping mechanism is provided on the inner wall of the pump body, wherein one end of the air pumping mechanism is exposed outside the pump body, and the other end of the air pumping mechanism is located inside the operating area.

[0008] Furthermore, the air pumping mechanism consists of a handle, a connecting rod, a telescopic column, a piston, and an air pump. The handle is rotatably connected to the top inner wall of the operating area, the connecting rod is hinged to one end of the bottom outer wall of the handle, the telescopic column is hinged to one end of the bottom of the connecting rod, the piston is fixedly connected to one end of the outer wall of the telescopic column, and the air pump is installed inside the pump body, with the piston slidably connected to the inner wall of the air pump. The piston consists of a hard plate fixedly connected to one end of the outer wall of the telescopic column and a rubber cup disposed on one side of the hard plate.

[0009] Furthermore, a one-way valve is fixedly connected to the inner wall of one end of the air pump, and an air outlet pipe with an air nozzle is fixedly connected to the inner wall of the one-way valve. An air vent is provided at equal intervals on the outer wall of the other end of the air pump. The air venting direction of the one-way valve is from the air pump to the air outlet pipe.

[0010] Furthermore, a rubber sleeve is bonded to one end of the outer wall of the top of the pump body, and the rubber sleeve covers the outside of the handle. The rubber sleeve can seal the top of the pump body without hindering the rotation of the handle, preventing dust from entering the pump body from the bottom of the rubber sleeve.

[0011] Furthermore, handle areas are provided through the outer walls on both sides of the pump body. Users can hold the handle areas to carry the pump body to different locations.

[0012] Furthermore, a material inlet is provided at the other end of the top outer wall of the pump body, and a screw cap is screwed onto the outer wall of the material inlet. After unscrewing the screw cap, it is convenient for the user to take out the air outlet pipe from the storage area.

[0013] Furthermore, a bottom frame is provided at the center of the outer wall of the pump body, and the bottom frame is provided with heat dissipation strips distributed at equal intervals. The bottom frame is located at the bottom of the air pump. During the back-and-forth movement of the piston, friction generates heat, causing the air pump to heat up. The heat dissipation strips can absorb some of the heat, improving the service life of the air pump.

[0014] Furthermore, support blocks are provided at both ends of the bottom outer wall of the pump body, and symmetrically distributed through slots are provided on both sides of the outer wall of the pump body. The support blocks are used to support the entire pump body, and the through slots not only save materials but also improve the strength of the pump body shell.

[0015] The beneficial effects of this utility model are:

[0016] This utility model proposes a portable air pump with an integrated pump body. The pump body is mainly divided into an operation area and a storage area, providing ample internal space for convenient air pumping. The pump body features a double inverted cone structure on the outside and a heat dissipation strip at the center of the bottom, ensuring overall structural stability and heat dissipation. Additionally, a handle area is provided on the outside of the pump body, with a large bearing area to prevent the pump from slipping off when carried. The pump has a simple and elegant appearance, is lightweight and convenient, and its overall design is compact and easy to carry.

[0017] In the air inflator mechanism, the handle, connecting rod, telescopic column, piston, and air pump work together to control the connecting rod to tilt back and forth when the handle is repeatedly pressed. This, in turn, controls the telescopic column to extend and retract inside the air pump, allowing the piston to continuously push and draw air, thus completing the air inflator operation. This device uses a manual mechanical pressing method to inflate tires at any time, is low in cost, and is easy to use. Attached Figure Description

[0024] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0025] Please refer to Figures 1-4This utility model proposes a portable air pump, including a pump body 1. One side of the inner wall of the pump body 1 is provided with an operation area 2 for mechanical operation, and the other side of the inner wall of the pump body 1 is provided with a storage area 3 for storing items. An air pumping mechanism 4 is provided on the inner wall of the pump body 1, wherein one end of the air pumping mechanism 4 is exposed outside the pump body 1, and the other end of the air pumping mechanism 4 is located inside the operation area 2.

[0026] The air pumping mechanism 4 consists of a handle 5, a connecting rod 6, a telescopic column 7, a piston 8, and an air pump 9. The handle 5 is rotatably connected to the top inner wall of the operating area 2. The connecting rod 6 is hinged to one end of the bottom outer wall of the handle 5. The telescopic column 7 is hinged to one end of the bottom of the connecting rod 6. The piston 8 is fixedly connected to one end of the outer wall of the telescopic column 7. The air pump 9 is installed inside the pump body 1, and the piston 8 is slidably connected to the inner wall of the air pump 9. The piston 8 consists of a hard plate fixedly connected to one end of the outer wall of the telescopic column 7 and a rubber cup disposed on one side of the hard plate.

[0027] In this embodiment, the pump body 1 adopts an integrated structure, which is mainly divided into an operation area 2 and a storage area 3. The internal space is large, which facilitates the air pumping mechanism 4 to perform air pumping operations. In addition, the pump body 1 adopts a double inverted cone structure on the outside, and a heat dissipation strip 16 is set in the middle of the bottom. The overall structure is stable and facilitates heat dissipation. Furthermore, a handle area 13 is provided on the outside of the pump body 1. The handle area 13 has a large force-bearing area, which can prevent the user from falling off when carrying the pump body 1. The pump body 1 has a simple and elegant appearance, is lightweight and convenient, and has a compact overall design that is easy to carry.

[0028] In the air pumping mechanism 4, through the cooperation of the handle 5, connecting rod 6, telescopic column 7, piston 8 and air pump 9, the connecting rod 6 can be controlled to tilt back and forth during the repeated pressing of the handle 5, thereby controlling the telescopic column 7 to extend and retract inside the air pump 9, so that the piston 8 can continuously push and suck air to complete the air pumping operation. This device adopts manual mechanical pressing air pumping, which can replenish tire pressure at any time, has low manufacturing cost and is easy to use.

[0029] A one-way valve 10 is fixedly connected to the inner wall of one end of the air pump 9, and an air outlet pipe 11 with an air nozzle is fixedly connected to the inner wall of the one-way valve 10. The outer wall of the other end of the air pump 9 has equidistantly distributed air vents. The airflow direction of the one-way valve 10 is from the air pump 9 to the air outlet pipe 11. The one-way valve 10 controls the airflow direction, ensuring that airflow can only enter the air outlet pipe 11 from the air pump 9, preventing airflow from flowing back from the air outlet pipe 11 into the air pump 9, thereby preventing airflow from the tire from flowing back into the air pump 9.

[0030] A rubber sleeve 12 is bonded to one end of the top outer wall of the pump body 1, and the rubber sleeve 12 covers the outside of the handle 5. The rubber sleeve 12 can seal the top of the pump body 1 without hindering the rotation of the handle 5, thus preventing dust from entering the pump body 1 from the bottom of the rubber sleeve 12.

[0031] The pump body 1 has handle areas 13 extending through its two outer walls. Users hold the handle areas 13 to carry the pump body 1 to different locations.

[0032] A material inlet is provided at the other end of the top outer wall of the pump body 1, and a screw cap 14 is screwed onto the outer wall of the material inlet. After unscrewing the screw cap 14, it is convenient for the user to take out the air outlet pipe 11 from the storage area 3.

[0033] A bottom frame 15 is provided at the center of the bottom outer wall of the pump body 1, and the bottom frame 15 is provided with heat dissipation strips 16 distributed at equal intervals. The bottom frame 15 is located at the bottom of the air pump 9. During the back-and-forth movement of the piston 8, friction generates heat, causing the air pump 9 to heat up. The heat dissipation strips 16 can absorb some of the heat, thereby improving the service life of the air pump.

[0034] Support blocks 17 are provided at both ends of the bottom outer wall of the pump body 1, and symmetrically distributed through grooves 18 are provided on both sides of the outer wall of the pump body 1. The support blocks 17 are used to support the entire pump body 1, and the through grooves 18 not only save materials, but also improve the strength of the outer shell of the pump body 1.

[0035] When using this air pump, the user can first hold the handle area 13 and carry the pump body 1 to the designated position. Then, unscrew the screw cap 14 to expose the material inlet, take out the air outlet pipe 11 with the air nozzle from the storage area 3, and then install the air nozzle onto the tire valve. After that, by repeatedly pressing the handle 5 to control the connecting rod 6 to tilt back and forth, the telescopic column 7 can be controlled to extend and retract inside the air pump 9, so that the piston 8 can continuously push and suck air. During the pushing process, the rubber cup will fit against the inner wall of the air pump 9 under the limit of the hard plate, and the air will enter the tire through the air outlet pipe 11. During the sucking process, the rubber cup will deform, allowing external air to enter the air pump 9 through the air vent at one end of the air pump 9. At this time, the one-way valve 10 can prevent the airflow in the tire from flowing back into the air pump 9. The cycle can be repeated to complete the inflation operation.

[0036] The pump body 1 adopts an integrated structure, which is mainly divided into an operation area 2 and a storage area 3. The internal space is large, the overall structure is stable and facilitates heat dissipation, and the handle area 13 has a large bearing area, which can prevent the user from falling off when carrying the pump body 1. The appearance is simple and elegant, lightweight and convenient, and the overall design is compact and easy to carry.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
