The operation principle of the gas pump is mainly to use the alternating electromagnet, with two irons, and the electromagnets provide a fixed frequency to change with the alternating current. The magnets continuously reciprocate, and the magnets can continuously move the air chamber to the air. Gas, and then can lose;: moving air. For example, the Taiwan side of the announcement. One example is the previous case, "Inflating the pump to prevent backflow and closing the valve." % 凊 Refer to the first chart - 冈^ - 丄 brother - figure, air pump 1, including gas to the body 2, pumping body 3 盥 diaphragm /, diaphragm group 4 and so on. Wherein the gas chamber body 2 can be further divided into an inlet chamber 21 and a pumping palace? 9 s ^ ^ is rolled to 22, as for the pumping body 3, covering the outside of the oxygen chamber body 2; when the pumping pain is too g, the pumping hole body 3 moves outward relative to the air chamber body 2, and can be forced to advance The air inlet 2 of the air chamber 21 draws in air, and when the pump body 3 moves inward relative to the air member's hole to the body 2, the air can be discharged from the pumping gas π 221; , T will be inside the m. π 911, ^ buckle 'value this over every 'to prevent air from flowing back from the inlet and outlet 211, need to be in the intake group 4. The conventional diaphragm group 4, including the two bodies 212, has a diaphragm 41 and a plug body 42. The diaphragm 41 and the plug body 42 have respective μ f ° and each of the holes 411 and 421. The diaphragm 41 and the plug can be clamped by the holes 411 m 3 201144604, 421, and placed on the shaft body 212 when the hole is closed; for example, the film group 4 can provide only a valve function. The one-way conventional membrane group 4, which can not be vented, is quite small because of the relatively small size of the diaphragm 41 and the smear. It is easy to assemble when the size and the body structure of the second 42 are assembled. For the split type 41, the person moves outward, causing the diaphragm 41 to close. Inaccurate, the formation of air may be like. In view of the structure of the conventional diaphragm group, there is a lack of Mg puller L > eight-, outer vortex 'inventors based on the accumulation of decades of rich vertical brakes in the industry* qt , 1 test, and a number of domestic and foreign patents and experience, strive to solve the problem, the completion of the invention. The inventor hopes that with this: P., Er Gu Shi < disciple' can do its best, and Bai Xian's own talents can be returned to the industry. SUMMARY OF THE INVENTION The present invention is directed to an "improvement of the structure of an anti-air recirculation diaphragm for a pump", and its main object is to provide an improved diaphragm structure which has the advantages of easy assembly, reliable closure, and difficulty in detachment. In order to achieve the above object, the present invention specifically provides that the diaphragm component body is formed with a membrane body, and an extension body is convexly disposed on one side of the membrane body, and a perforation is formed in the center of the body and the extension body to facilitate assembly. Axle body. [Embodiment] The following is a detailed description of the preferred embodiment of the present invention, which is described in detail below with respect to the details of the modification of the anti-air recirculation slab structure of the present invention, and the effects thereof. /, 201144604 '•月> Read the second and fourth pictures. (5) When weeping, from the ice case, "Improve the structure of the air-proof machine for the pump", the air chamber is pumped in the air chamber 22, The body 2 can be divided into the inlet chamber 21 ” to 22 and the shaft chamber 212 is provided with a shaft body 212. The diaphragm element 5 of the present invention is integrated with 匍, 〇, 3i ^ co. The membrane body 51 and the extension body are formed. The 52 I stretched body 52 is disposed on the film body 51 — ^ ^ c〇 ^ , and the center of the film body 51 and the extension body 52 is provided with a through hole 53 for the shaft body 212 . Since the film body 51 and the extension body 52 of the present invention are attached to the shaft body 212, the assembler only needs to perform one, # / , which can increase the productivity, and further, due to the film body. Although the process is convenient, the m μ body 51 and the extension body 52 are integrally formed into a film piece 5, and the overall volume thereof is large, and it is highly desirable to invade and obtain the assembly. In summary, the present invention "intelligence: the improvement of the structure of the anti-air recirculation diaphragm of the tiantian β ¥ seat", according to the forty-fourth article of the current patent law _ $ . 丄/<r 卞馀 疋, not yet Violation of Articles 21 to 24 of the same law, -+ ' - brothers one, ten, thirty, first, = ten, twenty-two or fourth Article 19, Item 4, 4 stipulations. This case is indeed (4), which was not seen in the publication or publicly used before the application, and is not a technology known to the public. Furthermore, the present invention effectively solves the problem of prior art _ long-standing problems and achieves long-term needs of related users and consumers, and it is corroborated that the present invention is not easily accomplished. The case is in full compliance with the "industry utilization" of the Patent Law, "newness" and "progressiveness", etc., and the patents should be submitted in accordance with the law, and the court should check the patents and approve the patents as soon as possible to protect the application. The intellectual property rights encourage innovation. [S] The present invention has been described with respect to the foregoing embodiments, but it can be changed without departing from the spirit of the invention, and can be understood by those skilled in the art. The foregoing preferred embodiment of the present invention is only one of the ways in which the principle of the present invention can be specifically implemented, but is not limited thereto, and should be defined in the scope of the appended patent application.
