[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] An air pump that is easy to maintain, such as Figures 1 to 5 As shown, the device includes a housing 1, a motor 2, a circuit board 3, and an inflation device 4. The motor 2, circuit board 3, and inflation device 4 are all housed inside the housing 1. The motor 2 drives the inflation device 4. The motor 2 is electrically connected to the circuit board 3. The inflation device 4 is preferably a piston cylinder structure. During operation, the motor 2 drives the piston of the piston cylinder to reciprocate. It should be noted that how the motor 2 drives the piston of the movable cylinder to reciprocate to achieve inflation is existing technology and will not be described in detail here.
[0025] The housing 1 is composed of an upper cover 5 and a lower shell 6. An inflation tube 24 is connected to the inflation device 4. The lower shell 6 has a receiving groove 23 for accommodating the inflation tube 24. By storing the inflation tube 24 in the receiving groove 23, the overall structure is more compact and convenient to take out and use at any time.
[0026] The upper cover 5 is provided with several positioning protrusions 15, and the lower shell 6 is provided with several positioning protrusions 16. Each of the positioning protrusions 16 has a positioning groove 17 that is adapted to the positioning protrusion. When the upper cover 5 and the lower shell 6 are assembled, the positioning protrusions are inserted into the positioning grooves 17 respectively. Through the cooperation between the positioning protrusions 15 and the positioning grooves 17, the relative stability of the upper cover 5 and the lower shell 6 is ensured, the overall structural strength of the shell 1 is improved, and the assembly of the shell 1 is more efficient.
[0027] Furthermore, each of the ends of several positioning protrusions 15 is provided with a magnetic ring 18, and each of the ends of several positioning protrusions 16 is provided with a magnetic ring 19. The magnetic rings 18 and 19 are magnetically attracted to each other. Through the magnetic attraction between the magnetic rings 18 and 19, the relative stability between the upper cover 5 and the lower shell 6 can be further ensured, which further improves the overall structural strength of the shell 1. Moreover, it can help the positioning protrusions to be inserted into the positioning grooves 17, thereby improving the assembly efficiency of the shell 1.
[0028] Several heat dissipation holes 22 are provided on both sides of the lower shell 6, and the several heat dissipation holes 22 are evenly distributed. The heat inside the shell 1 can be discharged to the outside through the heat dissipation holes 22, so as to avoid the normal operation of various components due to excessive temperature.
[0029] Both sides of the upper cover 5 are provided with protrusions 7, which are distributed along the diagonal direction of the upper cover 5. Both sides of the lower shell 6 are provided with clearance openings 9 to avoid the protrusions 7. The clearance openings 9 are adapted to the protrusions 7 and correspond to each other. The protrusions 7 are accommodated through the clearance openings 9, so that the upper cover 5 and the lower shell 6 can be smoothly assembled.
[0030] The protrusion 7 has a through hole 8, and the lower shell 6 has through holes 10 on both sides. When the upper cover 5 and the lower shell 6 are assembled, the through hole 8 and the through hole 10 are coaxially arranged. The corresponding positioning rods 11 are movably inserted into the through hole 8 and the through hole 10. The positioning rods 11 are adapted to the through hole 8 and the through hole 10. It should be noted that when the positioning rods 11 pass through the through hole 8 and the through hole 10, the upper cover 5 and the lower shell 6 cannot be separated. However, when the positioning rods 11 are disengaged from the through hole 10, the upper cover 5 and the lower shell 6 can be separated by external force.
[0031] A positioning plate 12 is snapped onto the protrusion 7. The positioning plate 12 is connected to the positioning rod 11. A pull ring 13 is provided on the positioning plate 12. The pull ring 13 allows the user to apply external force. The positioning plate 12 can drive the positioning rod 11 to move so that it disengages from the through hole 2 10 or passes through the through hole 2 10.
[0032] The upper cover 5 is provided with a support protrusion 14 for supporting the positioning rod 11. The positioning rod 11 is movably inserted through the support protrusion 14. After the positioning rod 11 is disengaged from the through hole 10, the support protrusion 14 supports the positioning rod 11 to prevent the positioning rod 11 from falling. The positioning rod 11 can be taken away from the lower shell 6 along with the upper cover 5.
[0033] The positioning plate 12 is provided with a positioning block 20, and the outer wall of the protrusion 7 is provided with a slot 21. The positioning block 20 can be engaged with the slot 21. The positioning block 20 is made of rubber.
[0034] It should be noted that the positioning block 20 is engaged with the slot 21 to ensure the stability of the positioning plate 12, thereby preventing the positioning rod 11 from moving arbitrarily and ensuring the stability of the positioning rod 11.
[0035] When disassembling the shell 1, first pull the pull ring 13 with external force to move the positioning plate 12 and make the positioning block 20 disengage from the slot 21. The positioning plate 12 drives the positioning rod 11 to move, and the positioning rod 11 disengages from the through hole 2 10. Then, the upper cover 5 and the lower shell 6 can be separated by external force.
[0036] When assembling the housing 1, first assemble the upper cover 5 and the lower housing 6, then move the positioning plate 12 so that the positioning block 20 is engaged in the slot 21. The positioning plate 12 drives the positioning rod 11 to move, and the positioning rod 11 is inserted into the through hole 2 10.
[0037] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
