They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figures 1 to 3A preferred embodiment of the floating connecting pipe assembly according to this application will be described in detail below. The floating connecting pipe assembly includes a main body 10, the main body 10 having a flow channel 101 and at least one side hole 102 located radially on and communicating with the flow channel 101, the flow channel 101 for fluid flow. The main body 10 also has at least one through-hole 103, each through-hole 103 located on the side of a side hole 102 away from the flow channel 101 and communicating with the corresponding side hole 102.

[0025] The floating connecting pipe assembly includes at least one sealing component 20 and at least one connector body 30. The sealing component 20 includes a first sealing element 21, which has a mounting cavity 2101. Each first sealing element 21 is installed in a side hole 102 such that the mounting cavity 2101 corresponds to a through port 103, and the inner wall of each side hole 102 near the flow channel 101 abuts against the first sealing element 21 disposed in the corresponding side hole 102. The connector body 30 has a through hole 301. Each connector body 30 is partially inserted into the first sealing element 21 in a side hole 102 and extends out from the corresponding mounting cavity 2101 through the corresponding through port 103. The through hole 301 of the connector body 30 inserted into the first sealing element 21 communicates with the flow channel 101. The portion of the connector body 30 located in the opening 103 is smaller than the size of the opening 103. Each connector body 30, at its end furthest from the corresponding first seal 21, is sealed to a pair of connecting pipes. Each first seal 21 is capable of elastic deformation, allowing the connector body 30 to be inserted into it to deflect, causing its axis to deviate from the axis of the corresponding opening 103. In this way, the main body 10 can be floatingly connected to the connecting pipe via the connector body 30, meaning the connecting pipe can be connected to the main body 10 on opposite axes, increasing assembly convenience and reducing assembly difficulty.

[0026] Preferably, each of the connector bodies 30 is deflected such that the angle between its axis and the axis of the corresponding port 103 is 2°.

[0027] refer to Figure 2Preferably, the two inner walls of each side hole 102 located in the direction of extension of the flow channel 101 abut against the first sealing member 21 placed in the side hole 102, and each first sealing member 21 is elastically deformed by the corresponding two side walls of the side hole 102. In this way, by sealing the first seal 21 to the side wall of the side hole 102 near the flow channel 101, fluid guided from the flow channel 101 to the through hole 301 is prevented from flowing through the gap between the first seal 21 and the side wall of the side hole 102 near the flow channel 101 to the side hole 102, causing fluid leakage; by sealing the first seal 21 to the side wall of the side hole 102 where the through opening 103 is formed, external dust is prevented from entering the side hole 102 through the gap between the part of the connector body 30 located in the through opening 103 and the edge of the through opening 103, and the gap between the first seal 21 and the side wall of the side hole 102 where the through opening 103 is formed, so as to avoid dust accumulating in the space of the side hole 102 outside the first seal 21 and affecting the deflection of the connector body 30.

[0028] refer to Figures 2 to 4 The connector body 30 includes a head 31 and a rod 32. One end of the rod 32 expands radially to form the head 31. The rod 32 and the head 31 together form the through hole 301. The size of the rod 32 is smaller than the size of the through hole 103. Each connector body 30 is assembled to the main body 10 such that the head 31 is inserted into the first sealing member 21 located in a side hole 102 and the rod 32 extends from the corresponding mounting cavity 2101 through the through hole 103.

The first sealing member 21 is assembled with the head 31 such that each inserting portion 212 is inserted into one of the through holes 3101 and the two abutting portions 211 are respectively placed on both sides of the head 31. The first sealing member 21 is disposed in the side hole 102 such that the two abutting portions 211 respectively abut against the two inner walls of the side hole 102 in the direction extending from the flow channel 101 and are compressed to undergo elastic deformation. The first sealing member 21 is injection molded into the head 31 of the connector body 30. In this way, the first seal 21 and the connector body 30 are interlocked, which increases the firmness of the connection between the two, while the connector body 30 provides support for the first seal 21.

[0030] Preferably, the head 31 forms a groove 3102 at one end away from the rod 32, which communicates with the through hole 3101. The groove 3102 is located on the outer periphery of the through hole 301, and one end of the abutment portion 211 near the inner insertion portion 212 is engaged with the groove 3102 to increase the firmness of the connection between the first seal 21 and the first seal 22.

When the main tube 11 and the cover plate 12 are welded together, the welding overflow groove 104 is filled with the portion of the cover plate 12 and / or the main tube 11 that has been heated and melted, so as to prevent the molten portion from flowing into the side hole 102 and reducing the actual moving space of the joint body 30.

[0035] In another embodiment, the cover plate 12 is detachably connected to the main tube 11 so that when the first seal 21 fails to seal, the first seal 21 and the joint body 30, which are integrally injection molded with the joint body 30, can be replaced as a whole by removing the cover plate 12.

[0036] In a preferred embodiment of the above embodiments, the cover plate 12 is threadedly connected to the main tube 11.
