[0049] A preferred embodiment is given below and combined with the accompanying drawings to more clearly and completely illustrate the present invention, but the present invention is not limited to the scope of the embodiment.

[0050] like Figure 1-Figure 7 As shown, the utility model provides a nozzle assembly 1, which includes a nozzle body 11 and an expansion piece 12. The nozzle body 11 is provided with a flow chamber 116 inside, and the flow chamber 116 is used for circulating gas; the expansion piece 12 is arranged in the wall of the nozzle body 11, and the inner side of the wall of the nozzle body 11 has a claw-type structure 111, and the position of the claw-type structure 111 is opposite to the position of the expansion piece 12 in the radial direction of the nozzle body 11; the expansion piece 12 can change its volume during the temperature change process, and the claw-type structure 111 is deformed with the volume change of the expansion piece 12, so that the flow area of ​​the flow chamber 116 changes.

[0051] In this embodiment, the position of the claw structure 111 and the position of the expansion piece 12 are directly opposite to each other in the radial direction of the nozzle body 11 so that the expansion piece 12 can fully act on the claw structure 111 when the volume changes; the volume of the expansion piece 12 changes during the temperature change, causing the claw structure 111 to deform, so that the flow area changes, thereby being able to adjust the flow rate of the gas to adjust the required temperature when the ambient temperature changes.

[0052] It should be noted that when the expansion piece 12 is heated, it expands and its volume increases, causing the claw-shaped structure 111 to deform toward the inside of the flow chamber 116. The flow area of ​​the flow chamber 116 becomes smaller, causing the gas flow to decrease and thus automatically lowering the water temperature; when the expansion piece 12 is cooled, it contracts and its volume decreases, causing the claw-shaped structure 111 to deform outwards. The flow area of ​​the flow chamber 116 becomes larger, causing the gas flow to increase and thus automatically raising the water temperature.

[0053] Reference Figure 1 and Figure 5It is understood that the expansion member 12 includes a membrane 121 and paraffin 122 disposed inside the membrane 121 , and the paraffin 122 expands when heated to deform the claw-shaped structure 111 .

[0054] In this embodiment, the wax 122 inside the expansion member 12 can expand when heated and deform the claw-shaped structure 111. The deformation of the claw-shaped structure 111 can change the flow area of ​​the flow chamber 116, that is, the wax 122 can expand when heated and adjust the temperature of the water outlet of the gas water heater.

[0055] It should be noted that the film 121 can prevent the paraffin 122 from directly contacting the claw structure 111 so as to cause the paraffin 122 to adhere to the claw structure 111, thereby preventing the paraffin 122 from entering the flow chamber 116 through the gap 1111 and causing blockage.

[0056] Reference Figure 1 and Figure 3 It is understood that the expansion member 12 is a cylindrical structure, and the expansion member 12 is arranged around the claw-shaped structure 111 .

[0057] In this embodiment, the expansion member 12 is a cylindrical structure and the arrangement of the expansion member 12 surrounding the claw-shaped structure 111 is conducive to deformation of the claw-shaped structure 111 when the volume of the expansion member 12 changes. When the volume of the expansion member 12 changes, the arrangement surrounding the claw-shaped structure 111 will result in a large contact area with the claw-shaped structure 111 and uniform contact, and such an arrangement makes it easier and better for the claw-shaped structure 111 to deform.

[0058] It should be noted that, in the present embodiment, the structure of the expansion member 12 and the position setting relative to the claw-shaped structure 111 are merely a preferred structure and position setting mode, but in any other alternative embodiment, the expansion member 12 may be any structure and position setting mode that can cause the claw-shaped structure 111 to deform.

[0059] Reference Figure 1 and Figure 3 It is understood that the claw structure 111 includes a plurality of sheets 1111 , and the plurality of sheets 1111 are arranged along the circumferential direction of the nozzle body 11 , and a gap 1112 is provided between two adjacent sheets 1111 in the circumferential direction.

[0060] In this embodiment, the claw structure 111 includes a plurality of sheets 1111, which is conducive to more uniform force applied to the claw structure 111 by the expansion member 12; and the gap 1112 between two adjacent sheets 1111 in the circumferential direction is conducive to deformation of the claw structure 111.

[0061] Reference Figure 1 and Figure 2It is understood that the claw structure 111 and the expansion member 12 are arranged at the air inlet end 114 of the nozzle body 11. The air outlet end 115 of the nozzle body 11 is provided with a guide portion 113, and the air inlet end 114 of the nozzle body 11 is provided with a threaded connection portion 112 outside.

[0062] In this embodiment, the nozzle body 11 is divided into an air inlet end 114 and an air outlet end 115. The air inlet end 114 of the nozzle body 11 is provided with a claw structure 111 and an expansion member 12 and a threaded connection portion 112 is provided on the outside. The air outlet end 115 of the nozzle body 11 is provided with a guide portion 113. The above-mentioned structure is conducive to simplifying the structure of the nozzle body 11. In addition, the threaded connection portion 112 is provided on the outside of the air inlet end 114 of the nozzle body 11, which is conducive to arranging the nozzle body 11 on the outer shell of the gas distribution pipe 2.

[0063] It should be noted that, refer to Figure 1 and Figure 4 It is further understood that a chamber for accommodating the expansion member 12 is provided at the end of the air inlet end, and a claw-shaped structure 111 is provided on the inner wall of the chamber facing the flow chamber 116 ; and an end cover 13 is provided at the end to limit the axial movement of the expansion member 12 .

[0064] Reference Figure 4 It is understood that the claw structure 111 includes four plates 1111 , and the four plates 1111 are evenly arranged along the circumferential direction of the nozzle body 11 .

[0065] In this embodiment, four plates 1111 of the claw-shaped structure 111 are evenly arranged in the circumferential direction of the nozzle body 11 .

[0066] Reference Figure 1 and Figure 2 It is understood that an end cover 13 is disposed on the outer end surface of the claw-shaped structure 111, and the end cover 13 is a circular ring structure.

[0067] In this embodiment, the provision of the end cover 13 is helpful to prevent the expansion member 12 from axially moving, so that the expansion member 12 can be reliably limited in the wall of the nozzle body 11 .

[0068] It should be noted that the end cover 13 also has the function of preventing gas leakage.

[0069] The utility model also discloses a gas distribution pipe 2, which comprises the nozzle assembly 1 as mentioned above, and a plurality of nozzle assemblies 1 are arranged at intervals on a gas distribution pipe housing 21.
