Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] This application provides an embodiment of a slit nozzle structure; please refer to the details below. Figures 1 to 6 .

[0044] The slit nozzle structure in this embodiment includes: a cavity 1 and a nozzle body 2. The cavity 1 has an installation groove 12, the shape of which matches the shape of the nozzle body 2. The inner walls on both sides of the installation groove 12 have symmetrical first pin mating surfaces 13. The nozzle body 2 has a corresponding second pin mating surface 22 for mating with the first pin mating surface 13 to form a pin hole. The nozzle body 2 is detachably installed in the installation groove 12 by means of a pin 3. The bottom of the installation groove 12 has a first slit channel 11 that communicates with the inside of the cavity 1. The nozzle body 2 has a second slit channel 21 that communicates with the first slit channel 11.

[0045] It should be noted that this slit nozzle structure enables quick installation and disassembly of the nozzle body 2 and the cavity 1 by using the pin 3, and the size and direction of the nozzle can be adjusted by replacing different nozzle bodies 2, thereby avoiding adverse effects on the film layer. It can save time in replacing the nozzle body 2, reduce operating and maintenance costs, and is irreplaceable.

[0046] The above is Embodiment 1 of a slit nozzle structure provided in this application. The following is Embodiment 2 of a slit nozzle structure provided in this application. Please refer to the following for details. Figures 1 to 15 .

[0047] The slit nozzle structure in this embodiment includes a cavity 1 and a nozzle body 2. The cavity 1 has a mounting groove 12, the shape of which matches the shape of the nozzle body 2. First pin mating surfaces 13 are symmetrically formed on the inner walls of both sides of the mounting groove 12. The nozzle body 2 has corresponding second pin mating surfaces 22 for mating with the first pin mating surfaces 13 to form pin holes. The nozzle body 2 is detachably mounted in the mounting groove 12 via pins 3. A first slit channel 11 communicating with the interior of the cavity 1 is formed at the bottom of the mounting groove 12. A second slit channel 21 is formed on the nozzle body 2, communicating with the first slit channel 11. Specifically, the number of pins 3 is at least two.

[0048] Understandably, when the nozzle body 2 is installed in the mounting slot 12 via the pin 3, the pin 3 will bear the weight of the nozzle body 2 to prevent the nozzle body 2 from falling off under the influence of gravity.

[0049] like Figure 1 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, the mating surface between the nozzle body 2 and the mounting groove 12 can be arc-shaped.

[0050] It is understandable that the mating surface between the nozzle body 2 and the mounting groove 12 can also be rectangular (e.g., Figure 12 As shown), trapezoidal (as shown) Figure 14 (as shown) or other combinations thereof, without limitation.

[0051] like Figures 7 to 9 As shown, multiple first pin mating surfaces 13 are symmetrically provided on the inner walls of both sides of the mounting groove 12. The number of second pin mating surfaces 22 is equal to the number of first pin mating surfaces 13, and they are arranged in a one-to-one correspondence. Preferably, the multiple first pin mating surfaces 13 are evenly distributed.

[0052] It should be noted that by setting multiple first pin mating surfaces 13 and corresponding second pin mating surfaces 22, the nozzle body 2 and the cavity 1 can be fixed by a greater number of pins 3, effectively increasing the connection strength between the two. Furthermore, when the contact surface between the nozzle body 2 and the mounting groove 12 is arc-shaped, the angle of the nozzle body 2 can be adjusted. Specifically, for example... Figure 10 and Figure 11 As shown, the nozzle body 2 can be rotated at a certain angle and then the pin 3 can be inserted to fix it, thereby realizing the angle adjustment of the nozzle body 2.

[0053] like Figure 5 As shown, the pin 3 is a circular pin 3, and both the first pin mating surface 13 and the second pin mating surface 22 can be arc-shaped. It is understood that the pin 3 can also be other regular or irregular shapes, which can be specifically set according to the actual situation, and are not limited here.

[0054] like Figure 1 As shown, a medium 4 is provided inside the cavity 1, and the medium 4 can be connected through the first slit channel 11 and the second slit channel 21.

[0055] In specific implementation, the nozzle body 2 is connected to the cavity 1, the nozzle body 2 is embedded in the mounting groove 12, and the first pin mating surface 13 on the mounting groove 12 and the second pin mating surface 22 on the nozzle body 2 are mated to form a pin hole. Then, the pin 3 is inserted into the pin hole to fix the cavity 1 and the nozzle body 2. At this time, the medium 4 in the cavity 1 can be connected through the first slit channel 11 and the second slit channel 21.

[0056] When it is necessary to change the nozzle inner diameter (i.e., the width of the second slit channel 21), the first slit channel 11 and the second slit channel 21 can be connected by changing the nozzle body 2 with a different inner diameter (e.g., ...). Figure 6 (As shown).

[0057] When it is necessary to adjust the nozzle spray angle, this can be achieved by replacing different nozzle bodies 2. Specifically, when the contact surface between the nozzle body 2 and the mounting groove 12 is arc-shaped, and there are multiple first pin mating surfaces 13 and second pin mating surfaces 22, the angle of the nozzle body 2 can also be adjusted by rotating the nozzle body 2 by a certain angle and fixing it (e.g., Figure 10 and Figure 11 (As shown).

[0058] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
