Description

Technical Field

[0001] This utility model belongs to the field of air pump technology, and specifically relates to an air pump that is easy to assemble. Background Technology

[0002] Air pumps, as commonly used gas delivery and compression devices, are widely used in medical, household, power tool, and automotive parts industries. Traditional air pumps generally suffer from a completely enclosed housing or fixed, non-removable components. This means that during daily use, when internal components such as control circuit boards or batteries malfunction or require cleaning or replacement, users often cannot disassemble them themselves and must rely on professionals for repairs, increasing maintenance costs.

[0003] In addition, existing air pumps also have certain defects in terms of structural stability. Since the top and bottom covers of the housing are mostly connected by snap-fit ​​or threaded screws, they lack precise positioning structures and stable limiting connections. During operation, vibration, impact, or airflow fluctuations can easily cause the connections to loosen or become misaligned, affecting the air pump's sealing performance and overall operational stability.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0005] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide an air pump that is easy to disassemble from the top cover and bottom cover of the housing for inspection, cleaning or replacement of the internal components of the housing, thereby improving the maintainability and service life of the air pump. Through positioning connection, it is more stable to use and easy for users to quickly identify and operate the air pump, thus solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an air pump, comprising a mounting housing, a bottom cover, and a top cover. The bottom cover is installed at the bottom of the mounting housing, and the top cover is installed at the top of the mounting housing. A plurality of connecting through-posts are evenly distributed on the inner side of the bottom cover, and a plurality of fixing through-posts are evenly distributed on the inner side of the top cover. The fixing through-posts and the connecting through-posts are connected one-to-one and fixed by fasteners passing through the connecting through-posts and the fixing through-posts, thereby allowing the bottom cover and the top cover to be detachably and fixedly installed at the upper and lower ends of the mounting housing, respectively.

[0007] Furthermore, the upper edge of the mounting housing is recessed with a first positioning groove, and the lower edge of the housing top cover is protruded with a first positioning edge. The first positioning edge can be embedded in the first positioning groove, thereby realizing the positioning connection between the housing top cover and the mounting housing.

[0008] Furthermore, the upper inner side of the mounting housing is uniformly recessed with several limiting slots, and the inner side of the housing top cover is uniformly provided with several limiting blocks. The several limiting blocks and the several limiting slots are connected one-to-one to form a limiting snap-fit ​​structure.

[0009] Furthermore, the lower edge of the mounting housing is provided with a second positioning clip, and the upper edge of the housing bottom cover is provided with a second positioning groove. The second positioning clip can be embedded in the second positioning groove, thereby realizing the positioning connection between the housing bottom cover and the mounting housing.

[0010] Furthermore, a control circuit board and a battery are installed inside the housing. The inner sides of the housing top cover are symmetrically provided with mounting posts, and the surface of the control circuit board is symmetrically provided with mounting holes on both sides. The mounting holes correspond to the mounting posts, and are connected and fixed by fasteners passing through the mounting holes and mounting posts, thereby fixing the control circuit board to the inner lower side of the housing top cover.

[0011] Furthermore, the inner sides of the top cover of the housing are symmetrically provided with positioning protrusions, and the control circuit board is symmetrically provided with positioning through holes on both sides of its surface. The positioning protrusions and the positioning through holes are inserted one-to-one to achieve positioning of the control circuit board.

[0012] Furthermore, the size of the first positioning slot is larger than the size of the first positioning edge.

[0013] Furthermore, the size of the second positioning slot is larger than the size of the second positioning edge.

[0014] The present invention has the following advantages: the inner side of the bottom cover of the housing is uniformly provided with a plurality of connecting through-posts, and the inner side of the top cover of the housing is uniformly provided with a plurality of fixing through-posts. The plurality of fixing through-posts and the plurality of connecting through-posts are connected one-to-one, and fasteners are used to pass through the connecting through-posts and connect and fix them to the fixing through-posts. Thus, the bottom cover and the top cover of the housing are detachably and fixedly installed at the upper and lower ends of the mounting housing, respectively. The air pump of the present invention allows for easy disassembly of the top cover and the bottom cover of the housing to inspect, clean or replace the internal components of the mounting housing, thereby improving the maintainability and service life of the air pump. Furthermore, the positioning connection makes it more stable to use and facilitates quick identification and operation by the user. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 5 As shown, an air pump includes a mounting housing 10, a housing bottom cover 20, and a housing top cover 30, wherein the housing bottom cover 20 is detachably mounted on the bottom of the mounting housing 10, and the housing top cover 30 is detachably mounted on the top of the mounting housing 10.

[0022] In practical implementation, the inner side of the bottom cover 20 of the housing is uniformly provided with a plurality of connecting through-posts 21, and the inner side of the top cover 30 of the housing is uniformly provided with a plurality of fixing through-posts 31. The fixing through-posts 31 and the connecting through-posts 21 are connected one-to-one, and fasteners are used to connect and fix them to the fixing through-posts 31 through the connecting through-posts 21. This allows the bottom cover 20 and the top cover 30 of the housing to be detachably and fixedly installed at the upper and lower ends of the mounting housing 10, respectively. The above structural design is simple, the assembly process is convenient, and it is beneficial for product manufacturing and subsequent maintenance. During use, the user can easily disassemble the top cover 30 and the bottom cover 20 of the housing to inspect, clean, or replace the internal components of the mounting housing 10, thereby improving the maintainability and service life of the air pump.

[0023] In practical implementation, the upper edge of the mounting housing 10 is recessed with a first positioning groove 11, and the lower edge of the housing top cover 30 is protruding with a first positioning edge 32. The size of the first positioning groove 11 is larger than the size of the first positioning edge 32. During assembly, the first positioning edge 32 can be embedded in the first positioning groove 11, thereby achieving a positioning connection between the housing top cover 30 and the mounting housing 10. This positioning structure effectively avoids problems such as offset or rotational misalignment of the housing top cover 30 during installation, improving overall assembly accuracy. In use, this structure not only ensures the stability of the top cover but also facilitates subsequent quick disassembly, assembly, and maintenance operations, improving the practicality and reliability of the equipment.

[0024] In practical implementation, the upper inner side of the mounting housing 10 is uniformly recessed with several limiting slots 12, and the inner side of the housing top cover 30 is uniformly provided with several limiting blocks 33. Each limiting block 33 corresponds one-to-one with a limiting slot 12. During assembly, each limiting block 33 is inserted into its corresponding limiting slot 12, forming a limiting engagement structure. This makes the connection between the housing top cover 30 and the mounting housing 10 more stable and reliable. This limiting engagement structure not only further enhances the fixing effect of the housing top cover 30 in the vertical and horizontal directions, preventing the top cover from loosening or shifting due to vibration or airflow fluctuations during use, but also provides clear positioning feedback during disassembly, facilitating quick identification and operation by maintenance personnel.

[0025] In practical implementation, the lower edge of the mounting housing 10 is provided with a second positioning retaining edge 13, and the upper edge of the housing bottom cover 20 is provided with a second positioning retaining groove 22. The size of the second positioning retaining groove 22 is larger than the size of the second positioning retaining edge 13. During assembly, the second positioning retaining edge 13 can be embedded in the second positioning retaining groove 22, thereby achieving a positioning connection between the housing bottom cover 20 and the mounting housing 10. In use, this structural design not only simplifies the installation process of the housing bottom cover 20 and ensures the orientation accuracy during assembly, but also improves the stability and consistency of the connection. In use, the second positioning retaining edge 13 and the second positioning retaining groove 22 work together to effectively prevent the housing bottom cover 20 from shaking or misaligning during operation, thereby ensuring that the air pump still has good structural stability and sealing performance under vibration, high load and other working conditions.

[0026] In practical implementation, a control circuit board 40 and a battery 50 are respectively installed inside the mounting housing 10. The control circuit board 40 is used to control the start and stop of the air pump and its operating parameters, and the battery 50 is used to provide power to the control circuit board 40 and other electrical components. The inner sides of the housing top cover 30 are symmetrically provided with mounting posts 34, and the surface of the control circuit board 40 is symmetrically provided with mounting holes 41. The mounting holes 41 correspond to the mounting posts 34, and are connected and fixed by fasteners passing through the mounting holes 41 and the mounting posts 34, thereby fixing the control circuit board 40 to the inner lower side of the housing top cover 30. The structure is simple and the installation is convenient.

[0027] In practical implementation, the inner sides of the top cover 30 of the housing are symmetrically provided with positioning protrusions 35, and the two sides of the surface of the control circuit board 40 are symmetrically provided with positioning through holes 42. During assembly, the positioning protrusions 35 and the positioning through holes 42 are inserted one-to-one to achieve precise positioning of the control circuit board 40. In use, this positioning structure can effectively prevent the control circuit board 40 from rotating or shifting due to vibration, drops or impacts during the operation of the air pump, further improving the reliability of the circuit connection and electrical safety. At the same time, this structure provides preliminary positioning assistance during the circuit board installation process, making the subsequent fastener installation smoother and improving the overall assembly efficiency.

[0028] In summary, the inner side of the bottom cover 20 of the housing is uniformly provided with a plurality of connecting through posts 21, and the inner side of the top cover 30 of the housing is uniformly provided with a plurality of fixing through posts 31. The plurality of fixing through posts 31 are connected one-to-one with the plurality of connecting through posts 21, and are fixed by fasteners passing through the connecting through posts 21 and the fixing through posts 31. Thus, the bottom cover 20 and the top cover 30 of the housing are detachably and fixedly installed at the upper and lower ends of the mounting housing 10, respectively. The air pump of this utility model allows for easy disassembly of the top cover and bottom cover of the housing to inspect, clean or replace the internal components of the mounting housing, thereby improving the maintainability and service life of the air pump. Furthermore, the positioning connection makes it more stable to use and facilitates quick identification and operation by the user.
