Measures must be taken to prevent fluid from leaking out of the box. One of the countermeasures is to use a method of ultrasonic welding of two box members. This ultrasonic fusion: It is the method of adding the ultrasonic connection with a certain pressure at the predetermined position of the Jiang Yu ^ ^ pieces, and the connection parts of the:, phase, and the pieces melt instantly and then follow. The structure of ultrasonic welding parts such as pumps and pump boxes. It is located in the first box 2: The first part of the wall: The flange 12 is formed, and the fitting groove 13 is provided at the opposite part of the flange η member 2. In the aspect, ί = ί = the opposite part of the first box member 1 is provided with a convex portion 23 embedded in the second box. The front end ☆ of this & part 23 is further provided with a slightly king-shaped protrusion 24. The first box member 1 ditch 13 toilets inside and outside the box + is also a rain box member 丨, 2 of 2: two: two. Therefore, the convex portion 23 is inserted while the fitting groove 13 is almost inserted, although some clearance is necessary. … After ’, so that the convex portion 23 is inserted into the inlay, and the cover ^ ^ ^, p 24 is connected to the posterity to check 1ς ^ by ten ei /, t.

V. Description of the invention (2) σ 'will push the supporting platform 3] side, that is, the state where the convex portion 23 is pushed = ^] 2, and the inner 32 of the second box member is added at the same time; The protrusion ^ of the connection part of the hone member 1 and the second box member 2 and the part of the box structure will melt, and the first box member 1 side box member 1 and The second box member / heart is solid. This result is in the ith closed pump box in the figure. To be integrated, it can become an internal space. [The problem to be solved by the invention] lies in the fact that there is a lifetime of so-called welding flashover. The flashover is a public one. ^ = ^ Pump box, the welding process is 24. And the i-th box member} repeating part of the white ', that is, as shown in Fig. 4, the resin) will melt, which will become (drag = the part shown by the thin section line, that is, reduce the amount of melted resin, clear that Welding flash. The strength of this repeated part is weakened. Therefore, the occurrence of ^ flash will be reduced, but the welded part will be taken from Ambassador Resin and the strength of this weld will have but the 'dissolved tree above' The meaning of the month is the amount of space), so the ratio of the fitting groove 13 and the second box of hibiscus resin (flash) in the melting section (resin melting section of the box member 1) will squeeze through the first gap. Squeeze through the narrow space between the two box members 1, 2 and phase 2 of the convex portion 23 (refer to arrows X, Y in Figure 4). That is, seven people's faces reach inside and outside the pump box. When narrow, even a small amount of welding Overfill: 2: The gap between 13 and convex part 23 is narrowly released to the inside and outside of the pump box. &Amp; As a result, it is easy to fill the gap. The described welding flash will prevent the impeller from rotating. Put it out of the pump box or if it is solidified there, it will go to the impeller to cut the welding flash.

498139 V. Description of the invention (3), and mixed with beverages and water will be related to major children and children. On the one hand, if the special material f is solidified there from the outside of the pump box, it will not worsen, and it will also bring a bad effect on the appearance of the pump box. Therefore, the purpose of the present invention is to provide 1 ;; The material is prevented from being released inside and outside the box, and it does not give a bad influence on this connection / benefit view, and for the size of the product ;: $ action and the outer structure of the box and the pump installation4.彳 Accuracy does not result in incorrect welding. [Method to solve the problem] In order to achieve this purpose, the integrated box structure of the fusion of the present invention, in order to make the box research = ^ 1 and the welding structure connected by a plurality of, lies in the first丨 Box_ The workshop uses ultrasonic waves to fuse into the convex groove structure of the fitting groove. ^ The relative position of the first box member is formed in the direction of the inside and outside of the box to form a pre-protrusion into the fitting groove. The pile 1 r Μ puts the gap between the present and the same, and at the same time, it is connected to the inner or outer side of the first phase member in the second box member, and then the second box member is located inside and outside the box and the first is recognized. With respect to the positioning member, the positioning member is positioned outside the vending bucket. Therefore, during the ultrasonic welding, the fitting groove of the i-box member and the overflow of the first birth are retained in the first solidification. This gap is because: even if there is more melting in the predetermined gap between the convex parts-the point is almost dissolved = the dazzling structure is set to be very large. That is, it is possible that all of the materials may stay in this gap than before. Therefore, a sufficient escape area is provided in the welding position during welding. It can increase the pressure of the welding or it can also apply a longer vibration when the body leaks. Π-bit strength is required to prevent the flow inside the box.

Furthermore, 'the gap between the fitting groove and the convex portion is set to be large, since it is not the positioning portion', it does not position the inside and outside directions of the two boxes. And 'another invention is to add the above-mentioned smelting structure, and then use ultrasonic waves to connect the inner bottom surface of the fitting groove, and at the same time, the gap in the direction of the inside and outside of the box formed while inside the groove, see The gap formed in the inner direction of the box is the same size as the gap formed in the outer box. Therefore, the flash material occurring at the front end of the convex portion and within the fitting groove will be uniformly retained in the inner and outer gaps of the convex portion. Therefore, the gap on one side is narrow, and the risk of the discharge of the spilled material to the inside or outside of the box will be further reduced. Moreover, another invention is that the above welding structure is added, and the component is connected to the first box. Opposite parts of the member are provided with either or both directions from the inward or outward direction of the embossed surface, as the overflow t generated when the member is ultrasonically welded to the second box member. Concave recess. Therefore, even if it cannot be accommodated in the gap formed between, it will stay in the vicinity of the root of the convex part and will not be released to the inside or outside of the box.
