New description: [New technical field] This creative system belongs to the field of piston pump in daily life auxiliary products, especially refers to a piston pump with integrated cylinder, which is different from traditional split body. In terms of the assembled cylinder structure, it has the advantages of simple structure, convenient processing and assembly, and low cost. [Prior Art] It is well known that the 'inflator' has been widely used in people's daily life to inflate appliances such as bicycle tires, motorcycle tires, balls, etc., to bring convenience to people. At present, the structure of the pump seen on the market is as shown in the first figure, which mainly comprises a cylinder and a piston element. «The sinusoidal piston element includes a piston rod 21 〇a and an operating handle 22〇a and a piston head 23〇a fixed to the lower end of the piston rod 210a, and the cylinder body includes a split upper cover 110a, a barrel 120a and a foot Step on the base i3〇a. The tubular body 120a has an upper and lower end opening structure, and the upper cover 11a is hermetically sealed to the upper end opening of the tubular body 12a via the seal ring 141a. The pedal base i3〇a is hermetically sealed to the lower end opening of the barrel 12〇a by the sealing ring 142a, and the piston rod 21〇a in the piston τ is extended by the through hole 111a in the cylinder upper cover 11a In the inner cavity of the barrel 120a, by operating the operating handle 220a, the piston head 23〇a can be slid up and down in the inner cavity of the barrel 12〇a, and the outside air is drawn into the inner cavity from the inlet on the barrel. Then, it is pressed into the appliance that needs to be pumped through the other air outlet on the cylinder to realize the function of inflation. However, the aforementioned conventional pump can realize the function of inflation, but the M363516 still has many problems to be improved. Among them, especially for the structural design of the body, one has formed a kind of field - which is considered as the split type in the above-mentioned content, and the habitually set the μ-shaped body H to produce the upper cover 11〇a, the body (10) and After the pedal base 13Ga components, and through the various airtight knots I, the split cylinder structure exists: the foot is mainly in the following aspects, one of which is the production of the mold More and more excessive molds are added into the ^ ^ + noon to make the mouth of the inventory and transport into = "the competitive disadvantage of the cost of printing; secondly, the parts will inevitably exist in the assembly of the planting quality; It is bound to bring about product defects and increase the defective rate of finished products, which will affect the quality of the products. 筒 In the process of production, the cylinders have to undergo the production of parts and components, and then assemble the two processes, which increases the complexity of production. The production cycle is prolonged, which seriously affects the production efficiency of the product. 13 [New content] ^The creator has the disadvantage that the traditional pump is assembled with separate components to create the 屮: and the non-performing rate is too high. U lacks and lacks, and then creates a piston pump with a one-piece cylinder. The m, the original design provides a body-shaped cylinder, "打乳涛" which contains a piston element and a cylinder a body, the cylinder body having an air storage chamber, the piston component comprises: an operating handle, a piston rod and a piston head, the piston head is located in a gas storage chamber of the cylinder body, the handle is located outside the cylinder body, and the piston rod is connected Between the operating handle and the piston head, and the pedal base and a bottom end, the cylinder body comprises an upper cover, a barrel body, and a M363516 cover, wherein the upper cover, the barrel body and the pedal base are integrally formed A through hole for mounting the piston rod is disposed at a center of the upper cover, and an opening for facilitating assembly of the piston head is disposed on the bottom surface of the pedal base, and the bottom end cover is integrally sealed to the opening. The size of the aforementioned opening is the same as the inner diameter of the barrel. The cover, the barrel body, the pedal base and the bottom end cover are all made of plastic material. In the piston element, the piston rod includes an inner tube and an outer tube, and an intake gap is maintained between the inner s and the outer tube; the piston head divides the gas storage chamber into an upper air chamber and a lower air chamber. The piston head has a first intermediate rotation chamber and a second intermediate rotation chamber separated from each other, and the side surface of the piston head is provided with an annular groove and a vent hole. The annular groove is provided with an upper and lower movable sealing ring. The vent hole communicates with the first-rotation cavity, and a plurality of upper through holes and a plurality of lower through holes are formed in the upper and lower surfaces of the second intermediate rotating cavity, and the upper and lower surfaces of the rotating cavity respectively Tr_jsg_ The knife sigh has a set of process soap to the valve and an upper stroke °, the lower stroke check valve can close or open the upper through hole valve can be closed or opened ΤΓu w mad early 13⁄4 control the second ^, the lower stroke one way The opening method is provided with the isolation or communication between the P chamber and the gas storage chamber; the operating handle is provided with a valve 2 ^ port ' MW communicating with the aforementioned intake gap, and the m end is further connected to the second intermediate chamber, by the air gap , the second middle thorns and spleen heart L 疋 inter-lact air passage, · cough out", the lower stroke one-way Forming a flow-to-storage chamber into which the inlet-and-mouth port communicates with the inner tube's lower-intermediate cavity of the inner tube, and the first venting chamber, the inner tube, and the out-and-out communication channel are connected by the venting hole. The upper and lower stroke check valves are formed into a rubber nail structure. The above-mentioned technical means 'piston pump has the following advantages. M363516 simplifies the production and buckle structure, because the upper stepped base in the cylinder is integrally formed. As a body and foot cylinder structure, there is no need to increase the sealing structure between the body base and the barrel body, and the cover/, body, pedal J, and mouth structure are as follows. Sealing ring, etc., the integrated structure has better structural strength and sealing performance. And the practice is second, more cost-effective, this ^ ο Φ ^ "special split-type cylinder structure and two m-type 'body structure relative to This can not only reduce the mold: two = two zero "have, such as lowering the cost of its mold, and after the number of parts has been reduced, it can save too much inventory of 11 dry T in the parts and accessories. In the second, it helps to improve the production assembly efficiency of the product, and zero reduction makes its tradition The process of the upper cover and the cylinder, the cylinder and the pedal base is completed in the process of the body molding process, and the assembly process of the multiple parts is saved, which greatly reduces the production assembly time.
