[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0064] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the accompanying drawings.Where possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0065] In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the specification of the present invention may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0066] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings contained in each term.

[0067] like Figure 1 and Figure 2 As shown, the utility model discloses a multi-way fluid connector, which includes: a connector body 10, a mounting plate 20, a water inlet connection pipe 30 and a fixing member 40. Among them, the upper part of the connector body 10 is provided with multiple access terminals 11 for connecting multiple sensors. The mounting plate 20 is provided with a rotation limit hole 21, and a plurality of mutually spaced limit portions 22 are provided at the inner edge of the rotation limit hole 21.

[0068] like Figure 3 and Figure 4 As shown, the water inlet connecting pipe 30 includes a first connecting portion 31, a mounting portion 32 and a second connecting portion 33 which are connected in sequence, and the first connecting portion 31 and the second connecting portion 33 are mutually connected. The water inlet of the joint body 10 is connected to the first connecting portion 31. The mounting portion 32 is installed in the rotation limiting hole 21 and is clamped with the corresponding limiting portion 22. The second connecting portion 33 is mainly used to connect an external joint.

[0069] Preferably, a plurality of mutually spaced limiting grooves 321 are provided on the outer wall surface of the mounting portion 32, and the limiting grooves 321 correspond to and match the limiting portion 22. The mounting portion 32 is fixed to the mounting plate 20 by the clamping of the limiting portion 22 and the limiting grooves 321. A groove is formed between two adjacent limiting portions 22, and the groove may preferably be in an arc shape. Accordingly, a convex portion is formed between two adjacent limiting grooves 321. The convex portion corresponds to and matches the groove. In this way, the mounting portion 32 corresponds to and matches the rotation limiting hole 21 and is connected.

[0070] In addition, the mounting portion 32 may preferably be in a circular ring shape, surrounding the outer circumference of the water inlet connecting pipe 30 and extending outward.

[0071] More preferably, a boss 34 protruding outward is further provided on the outer periphery of the water inlet connecting pipe 30, and the boss 34 is arranged close to the mounting portion 32. For example, the boss 34 can also be arranged in a circular ring shape, surrounding the outer periphery of the water inlet connecting pipe 30.

[0072] When the water inlet connecting pipe 30 rotates along the inner edge of the rotation limiting hole 21 to the corresponding limiting portion 22, the mounting portion 32 is engaged with the rotation limiting hole 21. The fixing member 40 is sleeved on the first connecting portion 31 to fix the water inlet connecting pipe 30 to the mounting plate 20.

[0073] When the water inlet connecting pipe 30 is fixedly connected to the mounting plate 20, the boss 34 and the fixing member 40 are respectively located on two opposite sides of the mounting plate 20. For example, the boss 34 and the fixing member 40 are respectively located at the upper and lower end surfaces of the mounting plate 20. In this way, the water inlet connecting pipe 30 and the mounting plate 20 can be firmly connected.

[0074] like Figure 5 As shown, preferably, the joint body 10 is a stepped structure, including an upper portion 12, a middle portion 13 and a lower portion 14 connected in sequence. The upper portion 12, the middle portion 13 and the lower portion 14 here can be set as cylindrical structures with successively smaller diameters.

[0075] At the same time, a plurality of mutually spaced mounting end surfaces 15 are provided on the upper outer wall surface of the joint body 10, and the connection hole of the access end 11 is provided on the mounting end surface 15. For example, the access end 11 surrounds the upper outer wall surface of the joint body 10. In this embodiment, the access end is not provided on the top of the joint body 10, which can effectively compress the axial volume.

[0076] The sensor installed at the access end 11 may include various forms, such as a pressure switch 50, a pressure gauge 60, and a water outlet quick connector 70, etc. Of course, this is only an example, and the sensor may also be in other forms, all of which are adapted to the multi-way fluid connector of the present application.

[0077] A flat clamping portion 16 may be provided on the outer wall surface of the middle portion 13 of the connector body 10 , for example in a C-shape, or a flat concave groove, to facilitate clamping and applying force by an external tool when installing or removing the connector body 10 .

[0078] like Figure 6 As shown, the limiting portion 22 on the mounting plate 20 may preferably be a protrusion, which protrudes outward along the inner edge of the rotation limiting hole 21 (along the direction close to the center position of the rotation limiting hole 21).

[0079] Of course, the structure of the limiting part 22 here can also adopt other forms, mainly playing a limiting role. The water inlet connecting pipe 30 can achieve the required rotation angle in the rotation limiting hole 21, and when it is rotated to the limiting part 22, the outer wall surface of the water inlet connecting pipe 30 and the limiting part 22 are mutually engaged, that is, the angle is adjusted to the right position. This is only an example of the structure of the limiting part 22, and it is not intended to be limiting, and all are within the protection scope of this application.

[0080] like Figure 7 and Figure 8 As shown, the water inlet connecting pipe 30 is installed in the rotation limit hole 21 of the mounting plate 20. The water inlet connecting pipe 30 rotates along the rotation limit hole 21, and after the angle is adjusted to the right position, the water inlet connecting pipe 30 is clamped and positioned with the limit part 22. The fixing member 40 is sleeved on the first connecting part 31 to fix the water inlet connecting pipe 30 and the mounting plate 20 to each other.

[0081] The fixing member 40 is preferably a locking nut. For example, the locking nut is C-shaped, and the locking nut is sleeved on the water inlet connecting pipe 30 through the opening of the C-shaped structure.

[0082] In addition, further, a plurality of notches 41 may be provided on the outer wall surface of the anti-loosening locking nut to facilitate the application of force with a wrench when removing the anti-loosening locking nut.

[0083] like Figure 1 As shown, in the present application, the first connection part 31 of the water inlet connection pipe 30 is provided with an external thread on the outside, and the inner hole of the first connection part 31 is provided with an internal thread for connecting the joint body 10. The second connection part 33 is provided with an external thread on the outside, and the inner hole of the second connection part 33 is provided with an internal thread for connecting the external joint. The first connection part 31 and the second connection part 33 are respectively provided with two sizes of threads, which can be compatible with the joints of internal and external threads. In this way, the water inlet connection pipe 30 and the external joint can have two sizes of sealed threaded connection methods.

[0084] The water inlet connecting pipe 30 and the lower part 14 of the joint body 10 can be connected in a variety of ways. For example, the first connecting part 31 of the water inlet connecting pipe 30 is provided with an external thread 311 and an internal thread 312, connected to the mounting plate 20 through the external thread 311, and connected to the lower part 14 of the joint body 10 through the internal thread 312.

[0085] Alternatively, the water inlet connecting pipe 30 and the joint body 10 may be connected by a sealed interference fit or a sealed threaded connection.

[0086] Alternatively, the water inlet connecting pipe 30 and the joint body 10 may be integrally injection molded, etc.

[0087] Of course, the connection method between the water inlet connecting pipe 30 and the joint body 10 here is only an example and is not intended to be a limitation of the connection method. Various connection methods are within the protection scope of this application.

[0088] The utility model also provides a control box, which is characterized in that the control box adopts the multi-way fluid connector as described above.

[0089] According to the above structural description, the multi-way fluid connector of the utility model is provided with a special shape of rotation limit hole (for example, a convex limit part) during installation, so that the entire connector body is connected and limited with the mounting plate through the water inlet connecting pipe. At the same time, a fixing member (for example, a locking nut) is used for fastening.

[0090] In the present application, the inlet end of the water inlet connecting pipe provides two specifications of internal and external threads (eg, G3 / 4 external thread and G1 / 4 internal thread) for connection, which can cover pipe diameters of more sizes.

[0091] For example, the multi-channel fluid connector in the above embodiment has three access ports that can simultaneously connect to a pressure switch, a pressure gauge, and a water outlet. According to the same design concept, the technical solution of the present application can be used for connecting more types of sensors to form a multi-channel adapter for easy replacement and adjustment.

[0092] In summary, the multi-way fluid connector of the utility model and the control box including the same have the following advantages:

[0093] 1. It can install multiple functional components and cover various connector requirements, thus solving the problems of poor integration and interface incompatibility of existing products.

[0094] Second, a special-shaped limiting structure is provided on the mounting plate. Through the cooperation between the multi-way fluid joint and the limiting structure, the multi-way fluid joint rotates relative to the limiting structure, thereby realizing the angle adjustment of the multi-way fluid joint.

[0095] 3. Easy to use, easy to adjust, and compatible with a variety of sensors.
