[0037] like Figures 1 to 4 The built-in structure of an air pump shown in the figure includes an air pump and an inner air membrane 5 and an outer air membrane 6 arranged outside the air pump. The air pump includes a housing 1, including the housing 1, an air pump body 2 composed of a diaphragm pump and a driving motor, a battery assembly 3 providing power for the air pump body 2, and an air nozzle assembly 4 connected to an external device to be inflated 7. The housing 1 is a roughly cylindrical structure, and the battery assembly 3, the air pump body 2, and the air nozzle assembly 4 are arranged in the inner cavity of the housing 1 from top to bottom.

[0038] A battery holder 11 for accommodating the battery assembly 3 is provided on the peripheral wall of the shell 1, one end of the battery holder 11 extends outward from the shell 1 and is open at the end, forming a connecting portion 111 protruding from the surface of the shell 1; the other end of the battery holder 11 extends toward the inner cavity of the shell 1, forming a fixing portion 112 for fixing the position of the battery assembly 3; an air guide gap 113 is provided between the peripheral wall of the battery holder 11 and the battery assembly 3, and an air guide hole 114 connecting the air guide gap 113 and the inner cavity of the shell 1 is provided on the peripheral wall of the battery holder 11. The air guide gap 113 is the air flow inlet of the entire air pump. When the air pump is working, the external air flow is sucked into the battery holder 11 through the air guide gap 113, and then guided to the inner cavity of the shell 1 through the air guide hole 114.

[0039] The air pump is built into the inner air membrane 5, and the outer air membrane 6 is sleeved on the outside of the inner air membrane 5. The outer air membrane 6 is connected to the part to be inflated, and the air pump fills gas into the to-be-inflated equipment 7 through the outer air membrane 6; for example, in the field of outdoor inflatable tents, the outer air membrane 6 and the air column of the inflatable tent are sleeved, and the air flow can be transmitted to the air column through the outer air membrane 6 to complete the inflation process of the air column.

[0040] A notch 61 for the connecting portion 111 to extend out is provided on the surface of the inner air film 5 and the outer air film 6 , and the edges of the notch 61 of the inner air film 5 and the outer air film 6 are sealed and connected by heat pressing.

[0041] A gland 17 is also sleeved on the connection portion 111 of the battery holder 11, and the gland 17 covers the surface of the outer air film 6 located at the notch 61 to fix the position of the outer air film 6. Specifically, an external thread is arranged around the circumference of the connection portion 111, and a fastening nut 18 is threadedly mounted on the external thread, and the gland 17 is located between the fastening nut 18 and the outer air film 6. Rotating the fastening nut 18 can make it move along the connection portion 111, press tightly against the surface of the gland 17, apply a fastening force to the gland 17, and prevent the gland 17 and the outer air film 6 from moving.

[0042] like Figure 5 and Figure 7 As shown, the battery assembly 3 is a lithium power battery, including a battery casing 31, a battery board 32 and a control panel 33 arranged in the battery casing 31. The energy supply of lithium power batteries has been widely used in the prior art, and can realize the power supply of electrical equipment. The battery casing 31 makes the entire battery assembly 3 form an integrated structure, which is convenient for the entire battery assembly 3 to be taken out, charged and replaced in the battery holder 11.

[0043] The battery case 31 is provided with a plurality of groups of jacks 35, and the battery holder 11 is provided with a limiting end hole 115 corresponding to the position of each group of jacks 35. The jacks 35 are correspondingly plugged into and matched with the limiting end holes 115. When the battery assembly 3 is inserted into the outer notch 61 of the battery holder 11, the limiting end holes 115 can quickly locate the position of each group of jacks 35, so that the jacks 35 are engaged with each limiting end hole 115 to fix the position of the battery case 31; in addition, the corresponding relationship between the limiting end holes 115 and the jacks 35 can prevent the battery assembly 3 from being installed incorrectly.

[0044] Furthermore, a plurality of conductive electrode sheets 34 are extended from the control panel 33 and extend into the corresponding sockets 35; the limiting end holes 115 are connected to the conductive parts electrically connected to the air pump body 2 through cables and terminals. When the socket 35 is plugged into the limiting end holes 115, the conductive electrode sheets 34 can quickly conduct electricity between the battery assembly 3 and the air pump body 2.

[0045] Furthermore, a button 36 is provided at one end of the battery assembly 3 away from the inner cavity, and the button 36 is connected to the control panel 33 via a push switch 37. The activation of the entire inflation pump is controlled by pressing the button 36.

[0046] Furthermore, a waterproof cover 38 is clamped at one end of the battery assembly 3 near the notch 61 of the battery seat 11, and the waterproof cover 38 covers the outer end surface of the battery casing 31. The waterproof cover 38 can prevent external water vapor from flowing into the battery assembly 3 through the notch 61 of the battery seat 11 and causing damage to the electrical components in the battery casing 31. A pull ring 39 is further provided on the waterproof cover 38, and the entire battery assembly 3 can be taken out of the battery seat 11 by pulling the pull ring 39.

[0047] After the external airflow flows into the inner cavity, it flows in through the air inlet end of the air pump body 2, and then flows out through the air outlet end of the air pump body 2. The air nozzle assembly 4 is connected to the air outlet end of the air pump body 2 to output the inflation airflow. Figure 8 and Fig. 9 As shown, the air nozzle assembly 4 includes an air valve seat 41 and an air nozzle connector 42, one end of the air valve seat 41 is sealed and docked with the air pump body 2, the interior of the air valve seat 41 is connected with the air outlet end, so that the gas ejected from the air pump body 2 flows into the air valve seat 41, and an air cavity for accommodating gas is formed inside the air valve seat 41; the air nozzle connector 42 is sealed and docked with one end of the air valve seat 41 away from the air pump body 2, and an air outlet 43 communicating with the internal air cavity of the air valve seat 41 is provided at the center of the air nozzle connector 42.

[0048] The inner air film 5 is provided with a nozzle fitting 44 connected to the nozzle connector 42. The center of the nozzle fitting 44 is connected to the air outlet 43 of the nozzle connector 42 and the outer air film 6, respectively, and the inner air film 5 and the outer circumference of the nozzle fitting 44 are sealed and connected. After the nozzle connector 42 and the nozzle fitting 44 are connected, since the outer air film 6 is sealed and connected to the inner air film 5 at the notch 61, the external air flow can only enter the outer air film 6 and the inflatable device 7 through the connected nozzle fitting 44; the outer circumference of the inner air film 5 and the nozzle fitting 44 is also sealed and connected, which can prevent the gas between the inner air film 5 and the outer air film 6 from flowing mutually, thereby ensuring the airtightness of the inflation process.

[0049] The air nozzle fitting 44 and the air nozzle connector 42 may be connected to each other through a silicone air tube, or may be directly connected through a common plug-in air nozzle structure or a rotary air nozzle structure.

[0050] Furthermore, the outer air film 6 is provided with an exhaust port 63, and an exhaust cover is detachably connected to the exhaust port 63. By opening the exhaust cover, the gas in the outer air film 6 and the device can be quickly released.

[0051] Furthermore, the outer air film 6 and the inner air film 5 are provided with a penetrating pump port 62 on their surfaces, and the outer air film 6 and the inner air film 5 are sealed and docked at the edge of the pump port 62 by means of heat pressing. The pump port 62 is used to facilitate the placement and removal of the housing 1 in the inner air film 5, so that the air pump can be quickly replaced when a failure occurs. The pump port 62 is not connected to the notch 61, and the gland 17 presses the notch 61, so that the external airflow can completely flow into the inner cavity of the housing through the air guide gap 113 during inflation.

[0052] In order to facilitate the installation of the components in the housing 1, the housing 1 in this embodiment is composed of two radially divided half shells. The two half shells can be disassembled to conveniently install the air pump body 2 into the inner cavity. Connecting columns 12 for plug-in matching are provided at the corresponding positions of the two half shells. One set of connecting columns 12 is inserted into the other set of connecting columns 12, and the two half shells are assembled into an integral structure. The center of the connecting column 12 is provided with a threaded hole 13, and at least one set of threaded holes 13 extends out of the circumferential end face of the half shell. The threaded fasteners are installed from the end face of the half shell to fasten the position of the two half shells.

[0053] Furthermore, the inner wall of the half shell is provided with a positioning ring 14 on the outer side of the air pump body 2. The size of the positioning ring 14 is set according to the outer wall size of the diaphragm pump or the drive motor. After assembly, the air pump body 2 is clamped in the positioning ring 14 to limit the radial movement of the air pump body 2. At the same time, due to the different radial dimensions of the air pump body 2, a step surface will be formed at the location where the size changes. Part of the positioning ring 14 is arranged on the step surface, which limits the radial movement of the air pump body 2 while limiting its axial movement, thereby maintaining the stability of the air pump body 2 in the housing 1.

[0054] Similarly, this embodiment is also provided with a structure for limiting the position of the air nozzle connection member 42. Figure 6 and Fig. 9 As shown, the air nozzle connector 42 includes a connecting ring 45 arranged around the air outlet 43, and the shell 1 is provided with an annular boss 15 at a position corresponding to the circumferential end surface of the connecting ring 45; a clamping rib 46 is protrudingly provided on the surface of the connecting ring 45, and a clamping groove 16 for the clamping rib 46 to extend into is provided on the inner side of the annular boss 15, and the position of the air nozzle connector 42 is further limited by the cooperation of the clamping rib 46 and the clamping groove 16.

[0055] The working process of this embodiment is as follows: the air pump body 2 and the air nozzle assembly 4 are assembled in the housing 1 to form a whole; the assembled housing 1 is installed in the self-placed pump port 62, the connecting portion 111 of the battery holder 11 extends out of the notch 61 of the outer air film 6, and the air nozzle connector 42 is connected to the air nozzle fitting 44 on the inner air film 5, so that the housing 1 can be built into the inner air film 5, and a gas flow path is formed in sequence through the outside, the air guide gap 113, the air guide hole 114, the air pump body 2, the air nozzle connector 42, the air nozzle fitting 44, the outer air film 6, and the inflatable device 7. Then the battery assembly 3 is installed in the battery holder 11, and the fastening nut 18 and the pressure cap 17 are tightened to fix the position of the housing 1 to prevent the battery holder 11 from being separated from the notch 61 of the outer air film 6. When the air pump fails, it is only necessary to separate the air nozzle connector 42 and the air nozzle fitting 44 and then remove the housing 1 from the pump port 62 to replace the air pump without destroying the outer air membrane 6 and the inner air membrane 5.

[0056] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
