[0031] See also Figures 1 to 3The utility model provides a nozzle assembly 100, including a mounting portion 1 and a working portion 2, the mounting portion 1 is formed with a mounting groove 11, and the mounting portion 1 is used to be installed on a storage component through the mounting groove 11; a flow channel 21 is formed inside the working portion 2, one end of the working portion 2 is connected to the mounting portion 1, the flow channel 21 is communicated with the mounting groove 11, and a spray hole 22 communicated with the flow channel 21 is formed at the other end of the working portion 2, and a protrusion 23 is formed on the outer surface of one end of the working portion 2 close to the spray hole 22. Specifically, the operator connects the mounting portion 1 and the operating portion 2 to each other, and then installs the container containing the sealant in the mounting groove 11 on the mounting portion 1, so that the sealant in the container can flow out of the container into the mounting groove 11. When the weld of the vehicle door needs to be sealed, the protrusion 23 is extended into the weld, and then the container is squeezed to make the sealant in the container enter the mounting groove 11, and then flow from the mounting groove 11 to the flow channel 21, and then flow out from the spray hole 22. The operator moves the nozzle assembly 100 along the weld, so that the weld is completely filled with sealant and the weld is sealed. Compared with directly squeezing the container to squeeze the sealant into the weld, the nozzle assembly 100 in this embodiment is used to spray the sealant, so that the weld can be sealed with extremely fine sealant, which not only meets the qualified standard of the product, but also improves the quality of the sealed weld. At the same time, since only a small amount of sealant is sprayed for sealing, the material cost is also greatly saved.

[0032] See also Figure 1 In one embodiment, the number of the protrusions 23 is at least four, and the four protrusions 23 are evenly distributed around the outer surface of the working part 2 and are arranged in a cross shape. By providing multiple protrusions 23, after the nozzle assembly 100 is inserted into the weld, the multiple protrusions 23 abut against the side wall of the weld, so that the nozzle assembly 100 can be prevented from slipping out of the weld. Only when the position needs to be moved, the nozzle assembly 100 is rotated so that the protrusions 23 do not abut against the side wall of the weld, so that the position of the nozzle assembly 100 can be moved.

[0033] See also Figures 1 to 3In one embodiment, the working part 2 includes a first connecting section 24 and a second connecting section 25, and the flow channel 21 includes a first flow sub-channel 211 and a second flow sub-channel 212. The first flow sub-channel 211 is arranged inside the first connecting section 24, and the second flow sub-channel 212 is arranged inside the second connecting section 25. The spray hole 22 and the protrusion 23 are both arranged in the second connecting section 25, and the spray hole 22 is connected with the second flow sub-channel 212. The second connecting section 25 is arranged in the first flow sub-channel 211, so that the first flow sub-channel 211 and the second flow sub-channel 212 are connected with each other. The nozzle assembly 100 is set as such a multi-section structure, which extends the length of the nozzle assembly 100, so that the pressure when the sealant is sprayed can be increased to ensure that the sealant enters the weld; at the same time, the multi-section setting, when one of the first connecting section 24 and the second connecting section 25 is damaged, only one of the first connecting section 24 and the second connecting section 25 needs to be replaced, and the entire working part 2 does not need to be replaced, which greatly reduces the maintenance cost.

[0034] See also Figure 1 and Figure 2 In one embodiment, a slider 241 is formed on the inner wall of the first flow sub-channel 211, and a slide groove 251 is formed on the outer surface of the second connecting section 25. The slide groove 251 extends along the length direction of the second connecting section 25, and the slider 241 is slidably installed in the slide groove 251. Through such an arrangement, the slider can move in the slide groove 251, so that the length of the nozzle assembly 100 can be adjusted, so that the nozzle assembly 100 can extend into welds of different depths, which greatly increases the applicable range of the nozzle assembly 100.

[0035] See also Figure 1 and Figure 2 In one embodiment, there are multiple sliders 241, and the multiple sliders 241 are evenly distributed along the inner wall of the first flow sub-channel 211. There are multiple slide grooves 251, and the multiple slide grooves 251 are evenly distributed along the outer surface of the second connecting section 25. The multiple sliders 241 are arranged in a one-to-one correspondence with the multiple slide grooves 251. By providing multiple sliders 241 and multiple slide grooves 251, the second connecting section 25 can be prevented from moving in the first flow sub-channel 211 in a direction perpendicular to the sliding direction during the sliding process.

[0036] See also Figure 1 and Figure 3In one embodiment, an inner wall of the first flow sub-channel 211 is formed with an inner thread 242, and an outer surface of the second connection section 25 is formed with an outer thread 252, and the outer thread 252 is threadedly connected with the inner thread 242, so that the second connection section 25 is installed in the first flow sub-channel 211. Specifically, the inner thread 242 covers the inner wall of the first flow sub-channel 211, so that when the outer thread 252 is threadedly connected with the inner thread 242, the outer thread 252 can be threadedly connected with the inner thread 242 at different positions, which is equivalent to the second connection section 25 sliding in the first flow sub-channel 211, so that the length of the nozzle assembly 100 can be adjusted, and the application range of the nozzle assembly 100 is greatly increased.

[0037] In one embodiment, the first connecting section 24 is formed with a first mounting hole communicating with the first flow sub-channel 211, the second connecting section 25 is formed with a second mounting hole communicating with the second flow sub-channel 212, and the nozzle assembly 100 further includes a locking member, which passes through the first mounting hole and is installed in the second mounting hole. The second connecting section 25 is connected to the first connecting section 24 by the locking member, so that the connection between the second connecting section 25 and the first connecting section 24 can be made more secure.

[0038] See also Figure 1 In one embodiment, the spray hole 22 is elliptical. The spray hole 22 is set to be elliptical. Compared with the circular spray hole 22 in the prior art, under different spray pressures, the speed of the sealant sprayed from the circular spray hole 22 is always greater than that of the elliptical spray hole 22. Therefore, the amount of sealant sprayed from the circular spray hole 22 is more difficult to control, resulting in a significant increase in waste. The use of the elliptical spray hole 22 can better control the amount of sealant sprayed; and as the major-minor axis ratio of the elliptical spray hole 22 increases, the speed of the sealant sprayed from the spray spray hole 22 also decreases.

[0039] In one embodiment, the nozzle assembly 100 further includes a dredging member, the outer diameter of which is smaller than the length of the minor axis of the spray hole 22. Specifically, after the nozzle assembly 100 is used, there will be pure sealant remaining in the flow channel 21, so that after a period of time, the sealant will block the spray hole, so that the operator can extend the dredging member from the spray hole 22 into the flow channel 21, so that the spray hole 22 can be dredged.

[0040] In one embodiment, the major axis of the spray hole 22 is 1mm to 2mm, and the minor axis of the spray hole 22 is 0.2mm to 0.8mm. In the prior art, the diameter of the spray hole 22 is 9mm, so that when in use, the spray hole 22 will spray a large amount of sealant, causing waste, and will also greatly increase the number of repairs. When the major axis of the spray hole 22 is 1mm to 2mm and the minor axis of the spray hole 22 is 0.2mm to 0.8mm, the amount of sealant used can be greatly reduced while ensuring the sealing quality, reducing waste and repairs; preferably, when the major axis of the spray hole 22 is 1.5mm and the minor axis of the spray hole 22 is 0.5mm, the effect is best.

[0041] In one embodiment, the length of the working portion 2 is 50 mm to 70 mm. When the length of the working portion 2 is 50 mm to 70 mm, it can adapt to the depth of the existing weld and ensure that the sealant can be filled into the weld; preferably, when the length of the working portion 2 is 60 mm, the effect is best.

[0042] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
