The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0030] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show the layers related to the present invention rather than being drawn according to the number, shape and size of the layers in actual implementation. In actual implementation, the type, quantity and proportion of each layer may be changed arbitrarily, and the layer layout may also be more complicated.

[0031] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention; however, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details.

[0032] Figure 1 FIG. 1 is a schematic diagram of a structurally reinforced built-in tent pump in one embodiment of the utility model. Figure 1 As shown, the housing 1 includes an inner housing 11 arranged inside the air column of the inflatable tent and an outer housing 12 arranged outside the air column of the inflatable tent. A soft rubber layer is provided at the edge of the inner housing 11, and the soft rubber layer is welded to the air column of the inflatable tent; specifically, the soft rubber layer is welded to the PVC bonding material arranged on the inner wall of the air column.

[0033] Specifically, a partition 13 is provided between the inner shell 11 and the outer shell 12, and the partition 13 is used to separate the space of the inner shell 11 from the space of the outer shell 12. The space in the inner shell 11 is used as the installation space of the inflatable component, and the space in the outer shell 12 is used as the installation space of the electronic device.

[0034] An outer protective shell 14 for strengthening the structure is provided on the top of the outer shell 12. The outer protective shell 14 fixes the outer wrapping cloth of the tent air column, so that the air pump body, the air column and the wrapping cloth are integrated, and the anti-explosion performance of the air column is enhanced.

[0035] The outer shell 12 is provided with an air inlet, and the inner shell 11 is provided with an air outlet; the partition 13 is provided with a through hole, and air flows into the inner shell 11 from the air inlet-through hole, and the air pump 2 in the inner shell 11 blows the air into the air outlet.

[0036] The inner shell 11 is provided with an air pump 2 for inflating the air column and an air pressure switch 3 for collecting the air pressure inside the air column and automatically closing when the air pressure inside the air column is greater than a preset threshold, and the air pressure switch 3 is connected to the air pump 2. Specifically, the air pump 2 is a diaphragm pump.

[0037] A one-way valve 4 is provided at the air outlet, the one-way valve 4 is provided with an air intake pipe 41, a detection pipe 42 is provided on the side of the air intake pipe 41, and the air pressure switch 3 is connected to the detection pipe 42 through a hose.

[0038] A power source 5 is provided inside the outer shell 12 , and a power supply end of the power source 5 is connected to the air pump 2 and the air pressure switch 3 .

[0039] The power source 5 includes a battery holder 51 and a detachable battery pack 52. The battery holder 51 is provided with a metal electrode sheet 511. The detachable battery pack 52 is connected to the metal electrode sheet 511. The power source 5 is powered by the metal electrode sheet 511. The metal electrode sheet 511 is connected to the air pump 2 and the air pressure switch through a wire.

[0040] The top of the detachable battery pack 52 is provided with a cover plate 521, one side of the cover plate 521 is provided with an elastic buckle 5211, and the corresponding position of the battery holder 51 is provided with a buckle slot 512, and the elastic buckle 5211 is detachably connected to the buckle slot 512. The present application utilizes the buckle and the buckle slot to realize the detachable connection between the detachable battery pack 52 and the battery holder 51.

[0041] In addition, the removable battery pack 52 is provided with a battery 522 and a charging switch circuit board 523. The bottom surface of the removable battery pack 52 is provided with a plurality of connection slots 524 corresponding to the positions of the metal electrode sheet 511. The connection slots 524 are provided with metal contacts, which are connected to the battery 522. The charging switch circuit board 523 is connected to the battery 522. The present application utilizes the connection slots 524 and the metal electrode sheet 511 to realize the electrical connection between the removable battery pack 52 and the battery holder 51.

[0042] The present application adopts a detachable battery pack to continue to supply power, which solves the problem that the built-in battery is inconvenient to charge. The air pump in the present application can directly replace the battery when it runs out of power.

[0043] In addition, the cover plate 521 is also provided with a switch button 5212 and a charging interface 5213, both of which are connected to the charging switch circuit board 523. When the switch button 5212 is pressed, the power supply 5 supplies power to the air pump 2 to start inflation.

[0044] When the present application is inflating, the air pump 2 works, and the air flow path of the air is: air inlet-through hole-one-way valve-air outlet. During the inflation process, the air pressure switch 3 collects the air pressure of the air inlet pipe 41 of the one-way valve 4 (at this time, the one-way valve 4 is open, and the air pressure in the air column is consistent with the air pressure of the air inlet pipe 41). When the air pressure reaches a preset threshold, the air pressure switch 4 automatically turns off the air pump 2 to prevent overcharging.

[0045] The invention welds the edge of the inner shell to the air column of the inflatable tent, so that the pump body and the air column are completely sealed as one. In addition, the invention also sets an outer protective shell on the outside of the pump body, so that the air pump body, the air column and the wrapping cloth are integrated, and the explosion-proof performance of the air column is enhanced.
