[0024] This embodiment is a connection device between a condenser and a water jet ejector.

[0025] like Figure 1-4 As shown, the device includes an inverted U-shaped pipe 1, with brackets 2 installed on the outer walls of both ends of the inverted U-shaped pipe 1. The inverted U-shaped pipe 1 includes a first bend 3, a second bend 4, an inspection pipe 5, and a connecting flange 6. The bracket 2 includes a support block 7, an arc-shaped plate 8, and an ear plate 9. An arc-shaped groove 10 is provided at one end of both the support block 7 and the arc-shaped plate 8. A rubber liner 11 is installed in the arc-shaped groove 10. A snap-fit ​​assembly 12 connects the arc-shaped plate 8 and the support block 7. The arc-shaped plate 8 is connected to the support block 7 through the snap-fit ​​assembly 12. The snap-fit ​​assembly 12 includes a slot 13, a snap-fit ​​hole 14, an insert 15, a mounting cavity 16, a compression spring 17, a limit block 18, a snap-fit ​​block 19, and a through hole 20. The slot 13 is opened on the upper and lower sides of the outer surface of one end of the support block 7. The snap-fit ​​hole 14 is opened on the upper and lower ends of the outer surface of the support block 7 near the arc-shaped groove 10. The insert 15 is fixedly installed on the upper and lower ends of the outer surface of one end of the arc-shaped plate 8.

[0026] The lower end of the snap-fit ​​hole 14 communicates with the slot 13, and the inverted U-shaped pipe 1 is located in the arc groove 10; the inspection pipe 5 is connected between the first bend 3 and the second bend 4 through the connecting flange 6; the ear plate 9 is fixedly installed on the outer surface of the upper and lower ends of the support block 7 at the end away from the arc groove 10, and the arc plate 8 is located on the outer surface of one end of the support block 7; the outer wall of the insert block 15 is inserted into the slot 13, and the upper outer wall of the snap-fit ​​block 19 is snapped into the snap-fit ​​hole 14; the mounting cavity 16 is opened inside the insert block 15, and the through hole 20 is opened in the... The lower end of the through hole 20 is connected to the mounting cavity 16 at the middle of the upper outer surface of the insert block 15. The compression spring 17 and the limiting block 18 are both located in the mounting cavity 16. The lower outer surface of the snap-fit ​​block 19 is fixedly connected to the middle of the upper outer surface of the limiting block 18. The compression spring 17 is fixedly installed between the bottom of the mounting cavity 16 and the lower outer surface of the limiting block 18.

[0027] It should be noted that this utility model is a connection device for a condenser and a water jet ejector. The original design connected the condenser and the water jet ejector through a straight pipe. The inverted U-shaped pipe 1, connected to the original straight pipe, can block working water from entering the condenser, preventing condensate contamination. Furthermore, to address the difficulty of cleaning the U-shaped pipe, a maintenance pipe 5 is provided. Disassembling the maintenance pipe 5 facilitates cleaning of the interior of the inverted U-shaped pipe 1 and the support 2, reducing cleaning difficulty. The support 2, fixed to an external wall or bracket, confines the inverted U-shaped pipe 1 between the support block 7 and the arc-shaped plate 8. When the arc plate 8 is in place, the snap-fit ​​block 19 is pressed and slides along the through hole 20. The snap-fit ​​block 19 drives the limiting block 18 to press the compression spring 17 in the mounting cavity 16. Then, the insert block 15 is inserted into the slot 13. When the snap-fit ​​block 19 reaches the lower part of the snap-fit ​​hole 14, the upper part of the snap-fit ​​block 19 is driven into the snap-fit ​​hole 14 due to the reaction force of the compression spring 17, thereby limiting the arc plate 8 and the arc groove 10 on the inverted U-shaped pipe 1. The inverted U-shaped pipe 1 is supported by the bracket 2. The rubber liner 11 can increase the stability of the connection between the bracket 2 and the inverted U-shaped pipe 1 and facilitate disassembly.
