Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to an air pump with a stepless speed regulation function. Background Art

[0002] An air pump is a mechanical device used to pump gas in or out, and it can transport gas from one place to another. It mainly changes the pressure of the gas through mechanical movement (such as rotation or reciprocating motion) to achieve the function of gas transportation, vacuum or pressurization. Air pumps are commonly used in various industrial, laboratory, medical, environmental control and other applications.

[0003] However, the speed control buttons of existing air pumps are usually smooth or rough in structure. The smooth speed control buttons have poor anti-slip performance and are inconvenient to use in humid environments or environments where hands are prone to sweating. The rough speed control buttons are difficult to clean and easily accumulate dust and dirt. The structure of the speed control buttons cannot be adjusted as needed according to the use environment.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1 and Figure 7 The utility model provides a technical solution: an air pump with a stepless speed regulation function, comprising an air pump body 1, a control groove 2 is provided on the upper surface of the air pump body 1, a speed regulating knob 3 is provided inside the control groove 2, an adjusting component is provided inside the speed regulating knob 3, a storage groove 14 is provided inside the speed regulating knob 3, and a locking component is provided inside the storage groove 14;

[0036] See also Figure 1-Figure 3 The adjusting assembly includes a fixed block 4, a driving block 10 and a driving disk 11. A limiting groove 5 is provided inside the fixed block 4. A driven rod 6 is connected inside the limiting groove 5. A closing block 7 is fixedly connected to one end of the driven rod 6. A protrusion 9 is fixedly connected to the upper surface of the driven rod 6. The driving disk 11 is sleeved on the outer surface of the driving block 10. A sliding groove 12 is provided inside the driving disk 11.

[0037] It is worth mentioning that the speed knob 3 is a stepless frequency conversion speed control button, which facilitates the air pump to achieve a smooth and continuous speed regulation process, and is convenient for the user to adjust the operating speed of the equipment very accurately according to needs, so as to better meet specific needs.

[0038] See also Figure 1-Figure 3 A notch 8 is provided on the outer surface of the speed regulating knob 3 , and the notch 8 is tightly fitted with the closing block 7 .

[0039] It should be noted that: the closing block 7 and the notch 8 fit tightly together to form a smooth outer surface structure of the speed knob 3, which is convenient for improving the comfort of the user in adjusting the speed knob 3, and is easier to clean and not easy to accumulate dust and dirt. After the closing block 7 and the notch 8 are separated from each other, the notch 8 on the outer surface of the speed knob 3 is exposed, so that the outer surface of the speed knob 3 presents an uneven structure, which is convenient for improving the anti-slip performance of the speed knob 3 and providing the user with better operational feedback.

[0040] See also Figure 1-Figure 4 The lower surface of the driven rod 6 is connected with a push rod 13, and the push rod 13 is in an inverted "L" shape.

[0041] The function of the push rod 13 is to connect the adjustment component and the locking component, which is conducive to improving the convenience of adjustment for the user.

[0042] See also Figure 1-Figure 6 There are eight closing blocks 7, which are centrally symmetrically distributed about the center of the speed regulating knob 3. The closing blocks 7 correspond to the notches 8 one by one. The slide groove 12 is an arc-shaped structure when viewed from above, and the connection between the protrusion 9 and the slide groove 12 is a sliding connection.

[0043] The principle of being able to adjust the outer surface structure of the speed control knob 3 is: the user can rotate the driving block 10, the driving block 10 drives the driving disk 11 to rotate, the driving disk 11 drives the protrusion 9 to move, and the protrusion 9 drives the driven rod 6 to make a linear motion inside the limiting groove 5, thereby adjusting the position of the closing block 7 connected to the driven rod 6. When the closing block 7 is tightly fitted with the notch 8, a smooth outer surface structure of the speed control knob 3 is formed. When the closing block 7 and the notch 8 are separated from each other, the outer surface of the speed control knob 3 presents an uneven structure.

[0044] See also Figure 5-Figure 7 The locking assembly includes a spring 15 and a positioning block 16. One end of the spring 15 is connected to the speed knob 3, and the other end of the spring 15 is fixedly connected to the positioning block 16. The diameter of the positioning block 16 is larger than the diameter of the push rod 13. The push rod 13 is connected to the receiving groove 14 in a sliding manner. The positioning block 16 forms a telescopic structure inside the receiving groove 14 through the spring 15. The positioning block 16 corresponds to the closing block 7 one by one.

[0045] The principle of locking the speed control knob 3 is as follows: when the closing block 7 is tightly fitted with the slot 8, the driving block 10 is further rotated to make the closing block 7 extend from the inside of the slot 8. At this time, the push rod 13 connected to the driven rod 6 will push the positioning block 16, so that the positioning block 16 extends from the inside of the storage groove 14 and fits tightly with the control groove 2. The speed control knob 3 is locked by the friction force between the positioning block 16 and the control groove 2, which helps to avoid the situation where the speed control button is accidentally touched and the output flow of the air pump changes.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
