Description

Technical Field

[0001] The present invention relates to the technical field of inflatable equipment, in particular to an inflatable pump which uses a roller to adjust the air pressure value, aiming to provide an inflatable equipment which is easy to operate and has comprehensive functions. Background Art

[0002] In daily life and industrial production, air pumps, as an important pneumatic tool, are widely used in various scenarios such as tire inflation, air mattress inflation, and sports equipment inflation. Traditional air pumps mostly rely on push buttons or knob switches to adjust the air pressure. These designs meet basic inflation needs to a certain extent, but there are still many shortcomings in actual operation and user experience.

[0003] The way to adjust the air pressure by pressing a button is usually to control the on and off of the airflow by frequently pressing the button, thereby increasing or decreasing the air pressure. Although this method is simple to operate, it has obvious disadvantages: first, the button is easily worn out due to long-term use, resulting in a decrease in sealing performance and affecting the inflation effect; second, the accuracy of air pressure regulation is limited, and it is difficult for users to accurately control the air pressure value by pressing the button several times, especially when fine-tuning is required, the operation is particularly difficult.

[0004] Although the knob switch method of adjusting air pressure improves the continuity of adjustment to a certain extent, it also has some problems. There is often a lack of intuitive correspondence between the rotation angle of the knob and the change in air pressure value. Users need to try and debug repeatedly to find the required air pressure value, which not only reduces the operating efficiency but also increases the difficulty of operation. In addition, after long-term use, the knob switch may also affect the adjustment accuracy and stability due to wear or looseness.

[0005] Therefore, the market is in urgent need of a new type of air pump that can accurately adjust the air pressure while maintaining ease of operation. This type of air pump needs to have a more durable and precise adjustment mechanism, as well as a more intuitive and user-friendly interface to meet the inflation needs of different users in different scenarios.

[0039] 2. Roller adjustment mechanism

[0040] (1) Structural composition

[0041] The roller adjustment mechanism 40 includes a pair of roller brackets 41, a roller 42 and a fixed frame 43. The two end shafts of the roller 42 are respectively set as a large shaft 421 and a small shaft 422, and are respectively mounted on the roller bracket 41 with an opening corresponding to the diameter thereof. A touch sensor 60 is installed at the bottom of the large shaft 421 for detecting the rotation of the roller 42 and transmitting the signal to the intelligent microprocessor on the control circuit board 17 for processing. The outer shaft end of the small shaft 422 is connected to the roller bracket 41 through a bearing seat 70 to ensure that the roller 42 can rotate stably.

[0042] The fixed frame 43 covers the outside of the roller bracket 41 and the roller 42, and reserves the upper half of the roller 42 for user operation. The user can adjust the air pressure value by rolling the roller 42. The rotation of the roller 42 will be captured by the intelligent microprocessor in real time and converted into corresponding air pressure value adjustment instructions.

[0043] (2) Working principle

[0044] When the user rotates the roller, the large shaft drives the touch sensor to generate an electrical signal, which is received by the microprocessor control unit and converted into an air pressure adjustment instruction. The microprocessor accurately calculates the required air pressure value based on the angle and speed of the roller rotation, and drives the compressor to adjust the output air pressure through a brushless DC motor (which can be a brushless or brushed DC motor). In addition, the roller bracket is designed with a U-shaped structure to ensure that the roller remains stable during rotation, reducing noise and wear.

[0045] 3. Control button assembly

[0046] The control button assembly 50 includes a power switch 51, a light switch 52 and a setting key 53. These buttons are all installed on the control circuit board 17, and touch sensors 60 are installed at corresponding positions. Users can press the corresponding buttons to turn on or off the air pump, control the switch of the emergency lighting device, or enter the setting interface to adjust parameters and other operations.

[0047] 4. Other functions
