DETAILED DESCRIPTION

[0021] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] The utility model is further described in detail below:

[0023] like Figure 1The figure shows a micro diaphragm pump, comprising an electric motor 1 and a diaphragm core 2, wherein the electric motor 1 is connected to the diaphragm core 2, and an electrode 12 is provided at the tail end of the electric motor 1, and the electrode 12 is used for electrical connection. The electric motor 1 is used to drive the diaphragm core 2 to work to pump fluid, and a first air outlet pipe 3 is provided at the front end 14 of the diaphragm core 2, and a second air outlet pipe 4 is also provided. The second air outlet pipe 4 is plugged into the first air outlet pipe 3 to form a front end column structure, or a connecting pipe 5 is provided between the first air outlet pipe 3 and the second air outlet pipe 4, and the connecting pipe 5 One end of the connecting pipe 5 is sealed and sleeved with the first air outlet pipe 3, and the other end of the connecting pipe 5 is sealed and sleeved with the second air outlet pipe 4. The connecting pipe 5 is used to axially connect the first air outlet pipe 3 and the second air outlet pipe 4 together and support to form a front end column structure; an air nozzle 6 is provided at the outer end of the second air outlet pipe 4, and an annular end surface 8 is provided in the circumference of the air nozzle 6 at the outer end. The air nozzle 6 is used to push open the valve 7 of the inflated object. The electric motor 1, diaphragm movement 2, first air outlet pipe 3, and second air outlet pipe 4 are distributed in sequence along the axial direction and form an overall columnar shape.

[0024] The second air outlet pipe 4 can be plugged into the first air outlet pipe 3 by a large pipe covering a small pipe. The second air outlet pipe 4 is set as a large pipe, and the first air outlet pipe 3 is set as a small pipe. The large pipe covering the small pipe can form a sealing structure through tight fit.

[0025] The electric motor 1 and the diaphragm movement 2 can adopt existing technology. The front end 14 of the diaphragm movement 2 is also provided with an air intake port 15. In this example, the air intake port 15 is located on an axially arranged air intake pipe connected to the front end 14. Of course, it can also be other structures. For example, instead of using an air intake pipe, an opening directly opened on the front end 14 serves as the air intake port 15.

[0026] In this example, if Figure 1 、 3 As shown, the first air outlet pipe 3, the connecting pipe 5, and the second air outlet pipe 4 are sequentially arranged along the axial direction to form a first cylinder 10, and the electric motor 1 and the diaphragm movement 2 are sequentially arranged along the axial direction to form a second cylinder 11. The first cylinder 10 and the second cylinder 11 are coaxially arranged, and the diameter of the first cylinder 10 is smaller than the diameter of the second cylinder 11. This makes the structure compact and all cylindrical, so there is no additional structure on the periphery that increases the volume.

[0027] Preferably, the connecting tube 5 is made of a silicone tube or a rubber tube, which is low in cost and convenient to assemble.

[0028] Furthermore, the silicone tube or rubber tube is tightly fitted onto the first air outlet pipe 3 and the second air outlet pipe 4 to achieve a sealed connection, thereby simplifying the sealing and further reducing the cost.

[0029] A magnet 9 is further provided in the circumferential direction of the gas nozzle 6 , and an annular end surface 8 of the magnet 9 serves as an annular end surface 8 at the outer end.

[0030] In this example, the second air outlet pipe 4 is integrally injection-molded with the air nozzle 6 , and the magnet 9 is a magnetic ring that is sleeved on the air nozzle 6 , so that the annular end face 8 of the magnet 9 serves as the annular end face 8 of the outer end.

[0031] like Figure 3 As shown, the valve 7 includes a valve core 17 and a docking end 18 located circumferentially of the valve core 17. When the air nozzle 6 is docked with the valve 7, the annular end face 8 docks with the docking end 18, and the valve 7 pushes open the valve core 17, thereby connecting the second air outlet pipe 4 and the valve 7 for inflation.

[0032] When the magnet 9 is used, the butt end 18 is magnetically butted against the annular end face 8 , thereby maintaining the butt joint between the air nozzle 6 and the valve 7 .

[0033] like Figure 2 、 3 The figure shows a micro diaphragm pump, comprising an electric motor 1 and a diaphragm movement 2. The electric motor 1 is connected to the diaphragm movement 2 and is used to drive the diaphragm movement 2 to pump fluid. The front end 14 of the diaphragm movement 2 is integrally provided with an air outlet pipe 13 extending forward. The outer end of the air outlet pipe 13 is provided with an air nozzle 6. The outer end is provided with an annular end surface 8 in the circumference of the air nozzle 6. The air nozzle 6 is used to push open the valve 7 of the inflated object. The electric motor 1, diaphragm movement 2 and air outlet pipe 13 are sequentially distributed along the axial direction and form a columnar structure. In this way, compared with the conventional diaphragm movement, the diaphragm movement 2 and the air outlet pipe 13 are sequentially distributed along the axial direction and form a columnar structure. Figure 1 The structure of the micro diaphragm pump shown is simpler. The outlet pipe 13 completely replaces the first column 10 composed of the first outlet pipe 3, the connecting pipe 5, and the second outlet pipe 4 distributed in sequence along the axial direction.

[0034] The air outlet pipe 13 constitutes the first column 10 , and the electric motor 1 and the diaphragm movement 2 are sequentially distributed along the axial direction to constitute the second column 11 . The first column 10 and the second column 11 are coaxially arranged, and the diameter of the first column 10 is smaller than the diameter of the second column 11 .

[0035] In some embodiments, as Figure 2 、 3 As shown, the diaphragm movement 2 includes a rear shell (16), and the front end portion 14 is integrally formed with an air outlet pipe 13 and an air nozzle 6 by injection molding to form a front end component, which is connected to the rear shell (16).

[0036] Furthermore, if Figure 2 As shown, it also includes a magnet 9, which is a magnetic ring. The magnetic ring is sleeved on the gas nozzle 6 of the front end component, so that the annular end surface 8 of the magnet 9 serves as the annular end surface 8 of the outer end.

[0037] In summary, the present disclosure includes an electric motor 1 and a diaphragm movement 2. The first air outlet pipe 3, the connecting pipe 5, and the second air outlet pipe 4 provided at the front end 14 of the diaphragm movement are distributed in sequence along the axial direction to form a first column 10, or the front end 14 is integrally provided with an air outlet pipe 13 extending forward as the first column 10. The electric motor 1 and the diaphragm movement 2 are distributed in sequence along the axial direction to form a second column 11. The second column 11 and the first column 10 are distributed in sequence along the axial direction to form a column structure, and an air nozzle 6 is provided at the outer end of the first column 10, and an annular end face 8 is provided at the outer end in the circumference of the air nozzle 6, thereby forming a micro diaphragm pump with a higher degree of completion, which is conducive to the subsequent further manufacture of a small air pump.

[0038] When understanding the present invention, if necessary, the above structure can refer to other appendixes. Figure 1 And understand, no further elaboration here.

[0039] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the scope of protection of the present invention are included in the scope of protection of the present invention.
