[0020] Figure 1 This is a schematic diagram of the structure of this utility model;

[0021] The components include: box body 1, first sleeve 2 with outward protrusion 2a, second sleeve 3, third sleeve 4 with inward protrusion 4a, pipe 5, elastic ring 6, and rubber ring 7. Detailed Implementation

[0022] like Figure 1 As shown, this embodiment includes a housing 1, a first sleeve 2, a second sleeve 3, a third sleeve 4, and a pipe 5.

[0023] In this embodiment, three boxes 1 are provided. The three boxes 1 are flat and have the same specifications and dimensions. The three boxes 1 are arranged vertically in an array from top to bottom. The top of the box 1 is provided with a water inlet and the bottom of the box 1 is provided with a water outlet. The water inlet and the water outlet are staggered from left to right. In other embodiments, two or other numbers of boxes 1 may be provided, and the dimensions are not limited to flat shape.

[0024] In this embodiment, a first internal thread is provided on the inner wall of the water inlet, and a second internal thread is provided on the inner wall of the water outlet.

[0025] The outer wall of the first sleeve 2 is provided with a first external thread corresponding to the first internal thread. The lower end of the first sleeve 2 is inserted into the water inlet and threadedly connected to the water inlet. If necessary, sealing tape is wrapped around the threaded connection. The outer wall of the upper end port of the first sleeve 2 is provided with an annular protrusion 2a.

[0026] The outer wall of the second sleeve 3 is provided with a second external thread corresponding to the second internal thread. The upper end of the second external thread is inserted into the water outlet and threadedly connected to the water outlet. Similarly, if necessary, sealing tape is also wrapped around the threaded connection.

[0027] One end of the third sleeve 4 has an annular inner protrusion 4a corresponding to the outer protrusion 2a. The lower end of the third sleeve 4 is fitted onto the upper end of the first sleeve 2. The outer protrusion 2a and the inner protrusion 4a are hooked together, so that the third sleeve 4 cannot disengage from the first sleeve 2 in the upward direction. The third sleeve 4 has a third internal thread that meshes with the second external thread. The upper end of the third sleeve 4 is threadedly connected to the lower end of the second sleeve 3.

[0028] In this embodiment, rotating the third sleeve 4 causes the third sleeve 4 to move upward relative to the second sleeve 3, which in turn tightens the first sleeve 2, ultimately achieving the connection between the first sleeve 2 and the second sleeve 3.

[0029] Preferably, when the third sleeve 4 is tightened with the second sleeve 3, the opposite end faces of the second sleeve 3 and the first sleeve 2 are in contact, clamping the outer protrusion 2a between the inner protrusion 4a and the lower end face of the first sleeve 2.

[0030] Furthermore, an elastic ring 6 is provided. The elastic ring 6 can be made of rubber. The elastic ring 6 is located between the upper end face of the first sleeve 2 and the lower end face of the second sleeve 3. When the third sleeve 4 is tightened with the second sleeve 3, the opposite end faces of the second sleeve 3 and the first sleeve 2 respectively abut against the two sides of the elastic ring 6, thereby enhancing the sealing effect and tightening effect.

[0031] Furthermore, the inner diameter of the first sleeve 2 is smaller than the inner diameter of the second sleeve 3, and the inner and outer diameters of the elastic ring 6 are the same as those of the second sleeve 3. With this structure, the second sleeve 3 does not need to have a very thick wall to cover the outward protrusion 2a.

[0032] Preferably, in this embodiment, annular grooves with opposite positions and shapes are provided on the end faces where the outer convex 2a and the inner convex 4a fit together, and a rubber ring 7 is also provided. The rubber ring 7 is disposed in the annular groove to further enhance the sealing and tightening effect.

[0033] Preferably, in this embodiment, the pipe 5 is a flexible pipe, which is wound around the three boxes 1 from top to bottom. In other embodiments, the pipe 5 can also be configured to wound around the three boxes 1 in a loop from top to bottom and then from bottom to top. In yet another embodiment, the pipe 5 can first completely cover the upper box 1 before winding it around the middle box 1, and then completely cover the middle box 1 before winding it around the lower box 1.

[0034] In this embodiment, waste smoke and wastewater carrying heat pass through three boxes 1 from top to bottom, and the water flowing in the pipe 5 collects the heat from the boxes 1. The three boxes 1 can be assembled and disassembled according to the actual situation. It is possible to choose to keep only two boxes 1, or to add other numbers of boxes 1. The number of boxes 1 can be selected according to the actual heat source heat.

[0035] In this embodiment, the water level flowing from the upper tank 1 into the lower tank 1 can also be limited by the depth to which the second sleeve 3 is inserted into the tank 1.

[0036] It should be noted that the descriptions of directions such as up, down, left, right, and vertical in this application are all based on the accompanying drawings in the specification and are only for the purpose of more intuitively describing the technical solution, and do not imply any limitation on the scope of protection.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
