[0031] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0032] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0033] In this embodiment of the invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] In this embodiment of the invention, the term "multiple" refers to two or more, and other quantifiers are similar.

[0036] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0037] Please see Figures 1 to 3 This utility model provides an interface structure 100 for a diaphragm pump 200. The interface structure 100 includes a cylindrical structure 1. The cylindrical structure 1 has a through vent 11 along the axial direction. The through vent 11 has a closed end 111 and an open end 112 at both ends. The cylindrical structure 1 also has a plurality of branch vents 12, which communicate with the through vent 11. The open end 112 of the through vent 11 is used to connect with a pipeline by thread and / or snap-fit.

[0038] This utility model, by setting an interface structure 100, allows both the air inlet 210 and the exhaust port 220 of the diaphragm pump 200 to adopt this interface structure 100. Each interface structure 100 includes a cylindrical structure 1, the cylindrical structure 1 having a through air hole 11 along the axial direction, the through air hole 11 having a closed end 111 and an open end 112 at both ends, the cylindrical structure 1 also having a plurality of branch air holes 12, the plurality of branch air holes 12 communicating with the through air hole 11, the open end 112 of the through air hole 11 being used to connect with the pipeline by thread and / or snap-fit, so that the air inlet 210 and the exhaust port 220 do not need to be located on both sides of the diaphragm pump 200.

[0039] Specifically, the interface structure 100 can be connected to other pipelines via internal and external threads. The open end 112 can have external threads on its outer wall or internal threads on its inner wall. In this embodiment, the inner wall of the open end 112 of the through-hole 11 has internal threads. By having internal threads on the inner wall of the open end 112 of the through-hole 11, the outer wall of the open end 112 can also be connected in other ways (e.g., snap-fit), allowing for selection based on specific requirements.

[0040] In other embodiments, the cylindrical structure 1 is recessed inward on the outer wall surface of the open end 112 to form an installation step 1121. The installation step 1121 has a recessed wall surface 1121a near the outer wall surface of the open end 112 and a step surface 1121b connected to the recessed wall surface 1121a. The interface structure 100 further includes a snap-fit ​​member 2, which is sleeved on the recessed wall surface 1121a and supported on the step surface 1121b.

[0041] It should be noted that, while the inner wall of the open end 112 of the through-hole 11 is provided with internal threads, the outer wall surface of the cylindrical structure 1 is recessed inward to form an installation step 1121, and the open end 112 is detachably connected to other pipelines by pressing the installation step 1121 against the clamping fitting 2; alternatively, only the inner wall of the open end 112 of the through-hole 11 may be provided with internal threads; or only the installation step 1121 may be used to press the clamping fitting 2 to achieve detachable connection between the open end 112 and other pipelines. The specific method can be selected according to the requirements, and by setting multiple methods, various different pipeline connection methods can be adapted.

[0042] Specifically, when using a snap-fit ​​connection method, such as... Figure 5 and Figure 6 As shown, the snap-fit ​​component 2 includes a first connecting arm 21 and a second connecting arm 22. One end of the first connecting arm 21 and one end of the second connecting arm 22 are rotatably connected together, and the other end of the first connecting arm 21 and the other end of the second connecting arm 22 are selectively clamped together. After the first connecting arm 21 and the second connecting arm 22 are respectively sleeved on the recessed wall surface 1121a, the other end of the first connecting arm 21 and the other end of the second connecting arm 22 are clamped together.

[0043] After the other ends of the first connecting arm 21 and the second connecting arm 22 are clamped together, they can be fixed to the stepped surface 1121b, thus making the connection more secure and further preventing the snap-fit ​​2 from coming off. More specifically, the other ends of the first connecting arm 21 and the second connecting arm 22 are fixed together with bolts and fixed to the stepped surface 1121b.

[0044] More specifically, such as Figure 3 As shown, the cylindrical structure 1 also includes an end cap 3, which has the mounting step 1121 and the recessed wall surface 1121a, and the end cap 3 is fitted onto the open end 112.

[0045] like Figure 1 and Figure 2 As shown, this utility model also provides a diaphragm pump 200 with an interface structure. The diaphragm pump 200 includes an air inlet 210 and an exhaust port 220, wherein the air inlet 210 and the exhaust port 220 adopt the interface structure 100 described above. It should be noted that the embodiments of the diaphragm pump 200 include embodiments of the interface structure 100 described above; the beneficial effects of the interface structure 100 can be applied to the diaphragm pump 200.

[0046] The air inlet 210 and the exhaust outlet 220 are located on the same wall surface of the diaphragm pump 200, and are spaced apart. Having the air inlet 210 and the exhaust outlet 220 on the same wall surface of the diaphragm pump 200, compared to the conventional method where the air inlet 210 and the exhaust outlet 220 can only be located on different wall surfaces, can more effectively reduce the radial dimension.

[0047] In a specific configuration, an installation gap is provided between the air inlet 210 and the exhaust outlet 220; the multiple branch air holes 12 on the air inlet 210 and the multiple branch air holes 12 on the exhaust outlet 220 are all arranged to avoid the installation gap, so as to avoid interference when the air inlet 210 and the exhaust outlet 220 are connected to the pipeline.

[0048] More specifically, the multiple branch air holes 12 on the air inlet 210 and the multiple branch air holes 12 on the exhaust outlet 220 are arranged alternately in the circumferential direction.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
