Description

Technical Field

[0001] This utility model relates to the field of electric air pump technology, specifically an electric air pump that can rotate 360 ​​degrees. Background Technology

[0002] An electric air pump is an electrically driven inflation device. It primarily uses an electric motor to drive a cylinder piston, thus supplying gas to tires or other items that need inflation. Electric air pumps are typically connected to the power source of an electric vehicle, using the motor to inflate the tires. This design makes the inflation process more efficient and convenient. The advantages of electric air pumps include high-efficiency inflation, ease of operation, accurate tire pressure monitoring, and emergency practicality. Driven by electricity, electric air pumps are far more efficient than foot-operated air pumps, capable of inflating tires in just a few minutes. They are particularly suitable for emergency use, saving a significant amount of time. Furthermore, electric air pumps are simple to operate; simply insert the valve into the tire and press a button for automatic inflation, greatly reducing physical exertion.

[0003] As per application number CN202222234547.0, this utility model embodiment provides an electric air pump. The cylinder contains several air inlet slots located at a predetermined distance from the lower end of the cylinder. These slots connect to the outside environment and the cylinder. When the piston moves downwards to the upper apex of the air inlet slot, outside air is drawn into the cylinder. When the piston moves upwards to cover the upper apex of the air inlet slot, the cylinder is isolated from the outside environment. The piston compresses the gas within the cylinder, performing work. When the gas pressure within the cylinder reaches the pressure threshold of the outlet valve, the gas within the cylinder moves outwards through the outlet valve. Through a unique air intake structure, when the piston reciprocates within the cylinder, the air inlet slots are exposed when it moves downwards to a predetermined position, allowing air to be drawn in. When it moves upwards to a predetermined position, the air inlet slots are covered, sealing the gas within the cylinder and thus achieving gas compression.

[0004] The above applications currently have the following shortcomings:

[0005] The inflation angle is relatively fixed, making it inconvenient to adjust the angle at will, which limits its application range.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an electric air pump that can rotate 360 ​​degrees, in order to achieve a more practical purpose. Utility Model Content

[0007] The purpose of this invention is to provide an electric air pump that can rotate 360 ​​degrees to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electric air pump that can rotate 360 ​​degrees, comprising an air hose assembly and a silicone O-ring. An air hose connector is installed at the upper end of the air hose assembly, and an air nozzle is provided at the bottom of the air hose assembly. A fixing nut is provided on the rear side of the air hose connector, and the silicone O-ring is located on the rear side of the fixing nut. An adapter ball is provided on the rear side of the silicone O-ring.

[0009] Furthermore, a silicone pad is provided on the rear side of the adapter ball head, and a spring retaining cap is provided on the rear side of the silicone pad.

[0010] Furthermore, a spring is provided on the rear side of the spring fixing cap, and a core assembly is installed on the rear side of the spring.

[0011] Furthermore, a rotating sleeve is provided on the outer side of the tracheal assembly, and a strap is provided on the left side of the rotating sleeve.

[0012] Furthermore, a second strap is provided on the right side of the rotating sleeve, and an installation notch is provided on the rear side of the rotating sleeve.

[0013] Furthermore, a rubber sleeve is installed inside the rotating sleeve, and the rubber sleeve is connected to the rotating sleeve by a sleeve connection.

[0014] Furthermore, the rotating sleeve is C-shaped, and the outer diameter of the rubber sleeve is the same as the outer diameter of the rotating sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model allows for complete rotation without dead angles during the assembly and use of the air tube assembly and air tube connector, making it more convenient to use and suitable for more scenarios. The air flow rate remains unaffected. The sleeve connection between the rotating sleeve and the rubber sleeve facilitates the assembly of the rubber sleeve. Simultaneously, rotating the rotating sleeve connects it to the air tube assembly, while the rubber sleeve protects the outer wall of the air tube assembly, preventing direct contact between the inner wall of the rotating sleeve and the air tube assembly, thus ensuring the integrity of the air tube assembly. Straps one and two secure the air tube assembly to the outside of the mechanism assembly, ensuring its stability and effectively preventing shaking. The mechanism assembly is driven by an electric motor, which rotates the gears, causing the connecting rod to reciprocate within the cylinder and generate gas. Attached Figure Description

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1-3 As shown, it includes a tracheal assembly 1 and a silicone O-ring 4. A tracheal connector 2 is installed at the upper end of the tracheal assembly 1, and an air nozzle 10 is provided at the bottom of the tracheal assembly 1. A fixing nut 3 is provided on the rear side of the tracheal connector 2, and a silicone O-ring 4 is provided on the rear side of the fixing nut 3. An adapter ball head 5 is provided on the rear side of the silicone O-ring 4.

[0025] In summary: When assembled and used with the air tube assembly 1 and air tube connector 2, it can rotate 360 ​​degrees without any blind spots, making it more convenient to use, suitable for more scenarios, and the air flow rate is not affected.

[0026] like Figures 1-3 As shown, a silicone pad 6 is placed on the rear side of the adapter ball head 5, and a spring fixing cap 7 is placed on the rear side of the silicone pad 6. A spring 8 is placed on the rear side of the spring fixing cap 7, and an engine assembly 9 is installed on the rear side of the spring 8. A rotating sleeve 11 is placed on the outer side of the air tube assembly 1, and a first strap 12 is placed on the left side of the rotating sleeve 11, a second strap 13 is placed on the right side of the rotating sleeve 11, and an installation notch 14 is opened on the rear side of the rotating sleeve 11. A rubber sleeve 15 is placed inside the rotating sleeve 11, and the rubber sleeve 15 is connected to the rotating sleeve 11 by a sleeve connection. The rotating sleeve 11 is C-shaped, and the outer diameter of the rubber sleeve 15 is the same as the outer diameter of the rotating sleeve 11.

[0027] In summary: the sleeve connection between the rotating sleeve 11 and the rubber sleeve 15 facilitates the assembly of the rubber sleeve 15. At the same time, rotating the rotating sleeve 11 connects it to the air tube assembly 1, and the rubber sleeve 15 protects the outer wall of the air tube assembly 1, preventing the inner wall of the rotating sleeve 11 from directly contacting the air tube assembly 1, thus ensuring the integrity of the air tube assembly 1. The first strap 12 and the second strap 13 can bind the air tube assembly 1 to the outside of the mechanism assembly 9, ensuring the stability of the air tube assembly 1 and effectively preventing the air tube assembly 1 from shaking. The mechanism assembly 9 is driven by an electric motor, which drives the gear to rotate, causing the connecting rod to reciprocate in the cylinder and generate gas.

[0028] Working principle: When this 360-degree rotating electric air pump is in use, it first... Figures 1-3 When the mechanism assembly 9 is opened, the electric motor drives the gear to rotate, causing the connecting rod to reciprocate in the cylinder and generate gas. The generated gas enters the air tube assembly 1 and is finally ejected from the air nozzle 10. At the same time, due to the connection between the air tube assembly 1 and the air tube connector 2, the air tube assembly 1 can rotate 360 ​​degrees without dead angles, and the airflow is not affected during the rotation, making it more convenient to use and suitable for more scenarios. The sleeve connection between the rotating sleeve 11 and the rubber sleeve 15 facilitates the assembly of the rubber sleeve 15. At the same time, rotating the rotating sleeve 11 connects it to the air tube assembly 1, and the rubber sleeve 15 protects the outer wall of the air tube assembly 1, preventing the inner wall of the rotating sleeve 11 from directly contacting the air tube assembly 1, thus ensuring the integrity of the air tube assembly 1. The first strap 12 and the second strap 13 can bind the air tube assembly 1 to the outside of the mechanism assembly 9, ensuring the stability of the air tube assembly 1 and effectively preventing the air tube assembly 1 from shaking.
