[0030] See also Figure 1-3 The utility model provides a technical solution: a vehicle-mounted air pump with a hose reel, comprising:

[0031] The housing comprises a base 1, a baffle 2 and a top cover 3 which are mutually snap-fitted or screwed together;

[0032] A hose reel 4 is disposed within the housing and includes a base plate 41 positioned on the base 1 and a hose reel 42 connected to the base plate 41 via a coil spring. The base plate 41 and the hose reel 42 have interconnected cavities. A locking plate 43 is disposed on the base plate 41, a locking element 7 being slidably disposed on the locking plate 43, and a locking groove 45 is disposed on the hose reel 42 for correspondingly locking with the locking element 7.

[0033] The inflation tube 5 is passed through the housing through the opening 21 and is wound around the hose reel 42 , with its inner end positioned on the positioning tube of the hose reel 42 and its inner wall communicating with the inner cavity of the hose reel 42 ;

[0034] The air pump 6 is positioned on the base plate 41 and communicated with the inner cavity thereof through a connecting pipe 61 .

[0035] In addition, if Figure 1 、2 As shown, a mounting box is provided on the base 1 and the enclosure 2, and accessories such as an inflation tube 5 and an inflation joint are provided inside. The bottom of the mounting box of the base 1 is connected with a flip cover by a snap buckle, and heat dissipation holes are provided on the mounting box and the flip cover.

[0036] The base 1 is provided with an arc-shaped partition 11 between the hose reel 4 and the air pump 6 , with the concave surface facing the hose reel 4 .

[0037] The locking slot 45 is a ratchet-like structure. A slide 44 is radially disposed on the locking disc 43 and extends through one side of the housing. The locking element 7 slides within the slide 44 via a pressing block 72. A resilient reset element is disposed between the outer side of a side plate 73 of the pressing block 72 and the slide 44. This design, combined with the reel's rotating structure, allows for multi-point locking of the locking element 7 and the reel 42, improving ease of use.

[0038] The inner end of the locking element 7 extends downward and penetrates the locking disk 43 to provide an arc-shaped locking block 71 , and the ratchet structure is provided with a bayonet 46 that abuts against the arc-shaped locking block 71 to improve the locking stability of the structure.

[0039] The opening 21 is located in an annular positioning groove 22 circumferentially provided on the enclosure 2 , and the outer end of the inflation tube 5 is embedded and positioned in the annular positioning groove 22 , so as to facilitate the storage and positioning of the outer end of the inflation tube 5 .

[0040] The base 1 is provided with a first heat dissipation hole 12 with an L-shaped distribution corresponding to the appearance of the air pump 6 at the bottom, and a second heat dissipation hole 23 is provided on the annular positioning groove 22 to improve the heat dissipation efficiency of the heating components in the air pump and ensure efficient and safe use.

[0041] The working principle of a vehicle-mounted air pump with a hose reel of this embodiment includes the following: when the length of the air tube 5 needs to be controlled, the pressing block 72 is pressed, so that the locking member 7 is pushed inward, and the arc-shaped locking block 71 moves radially and disengages from the bayonet 46. At this time, the hose reel 42 can rotate and rewind the air tube 5 through the coil spring, or pull the outer end of the air tube 5 outward to lengthen it; releasing the pressing block 72 causes the reset elastic member to move the locking member 7 outward to reset, and the arc-shaped locking block 71 moves outward and is guided by the arc-shaped guide surface of the ratchet structure and is engaged in the bayonet 46 to achieve structural locking. When restarting, the operation panel on the top cover 3 is operated to make the air pump pressurize the gas and perform the inflation operation through the connecting pipe 61, the inner cavity of the base plate 41, the inner cavity of the hose reel 42, and the air tube 5.

[0042] In summary, due to the adoption of the above technical solution, the vehicle-mounted air pump with a hose reel of this embodiment has the following beneficial effects compared to the prior art:

[0043] The utility model provides a hose reel between the inflation tube and the inflation pump, and the three are connected in sections. The gas in the inner cavity of the hose reel is guided to realize the functions of inflation and inflation tube length retraction and extension. The multi-point locking structure of the ratchet structure and the arc-shaped locking block is combined to improve the locking stability of the structure. Based on the inflation pump and other heat-generating accessories in the vacuum cleaner, the heat dissipation holes on the shell are designed to ensure safe and efficient inflation and improve the convenience of using the vehicle-mounted air pump.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
