[0058] Please refer to Figure 17 and Figure 18 , the nozzle assembly 100 further comprises a disassembly support 30, the disassembly support 30 is provided with a nozzle avoiding part 31 and a plurality of disassembly parts 32 arranged around the nozzle avoiding part 31, and the disassembly part 32 is provided with a second guide inclined surface 33. The clamping mechanism 20 is also used to carry the connected nozzle assembly 10 to press down on the disassembly support 30, so that the nozzle 110 is aligned with the nozzle avoiding part 31, and the second guide inclined surface 33 guides the clamping jaw 22 to open when it is extruded, thereby releasing the nozzle assembly 10 from the base 21. That is, during the disassembly and placement of the nozzle assembly 100 connected with the nozzle assembly 10 on the disassembly support 30, because the clamping mechanism 20 in the nozzle assembly 100 is connected with the nozzle assembly 10, the clamping jaw 22 cooperates with the side of the movable top plate 120 of the nozzle assembly 10 away from the fixed seat 11, and the first matching inclined surface 221 of the clamping jaw 22 contacts and cooperates with the side of the movable top plate 120 away from the fixed seat 11, so that the nozzle assembly 100 is used to disassemble the nozzle assembly 10, so that the plurality of clamping jaws 22 are pressed against each other with the disassembly part 32 of the disassembly support 30, and the first matching inclined surface 221 of the clamping jaw 22 and the second guide inclined surface 33 slide together, that is, the second guide inclined surface 33 extrudes the clamping jaw 22 upward to guide the clamping jaw 22 to open, thereby achieving the purpose of releasing the nozzle assembly 10 from the base 21.

[0059] It should be noted that when the nozzle assembly 10 is assembled on the disassembly support 30, the edge of the second guide inclined surface 33 of the disassembly part 32 exceeds or is flush with the edge of the first guide inclined surface 122, so that the second guide inclined surface 33 can extrude the clamping jaw 22 and guide the clamping jaw 22 to open. The second guide inclined surface 33 is used to open the clamping jaw 22, so that the clamping jaw 22 and the movable top plate 120 of the nozzle assembly 10 are decoupled.

[0060] Please refer to Figure 17 and Figure 18Further, in some preferred embodiments, the dismounting part 32 further comprises a side flat surface 34 connected with the second guide slope 33. When the nozzle assembly 10 is assembled on the dismounting support 30, the edge of the second guide slope 33 is beyond or flush with the edge of the first guide slope 122, and the side flat surface 34 of the dismounting part 32 is located outside the first guide slope 122 of the movable top plate 120 or flush with the edge of the first guide slope 122. By designing the edge of the second guide slope 33 to be beyond or flush with the first guide slope 122, it can be ensured that the second guide slope 33 presses and guides the clamping jaw 22 to open, and by designing the side flat surface 34 to be located outside the first guide slope 122 or flush with the edge of the first guide slope 122, it can be ensured that the dismounting part 32 has sufficient space to open the plurality of clamping jaws 22, and after the nozzle 11 is aligned with the nozzle avoiding part 31 of the dismounting support 30, the clamping jaw 22 and the nozzle assembly 10 can be fully decoupled by using the second guide slope 33 to open the clamping jaw 22 or further using the side flat surface 34 to open the clamping jaw 22.

[0061] Further, as mentioned above, Figure 17 The dismounting support 30 further comprises a magnetic piece 35, which is arranged on both sides of the nozzle avoiding part 31. The magnetic piece 35 is arranged on the upper surface of the dismounting support 30 and is located between the nozzle avoiding part 31 and the dismounting part 32. Specifically, the magnetic piece 35 is a magnet. When the clamping mechanism 20 presses the connected nozzle assembly 10 carried thereby downwardly toward the dismounting support 30, the nozzle 11 is aligned with the nozzle avoiding part 31, the magnetic piece 35 is used to contact and fix the movable top plate 120, the clamping jaw 22 is in contact with the side surface of the movable top plate 120 away from the fixed base 11, and then the clamping jaw 22 is in sliding contact with the second guide slope 33 of the dismounting part 32, so that the second guide slope 33 presses and guides the clamping jaw 22 to open, thereby releasing the nozzle assembly 10 from the base 21. During the process of pressing and guiding the clamping jaw 22 to open by the second guide slope 33, the magnetic piece 35 is used to prevent the nozzle assembly 10 from moving in the nozzle avoiding part 31.

[0062] Further, as mentioned above, Figure 17 and Figure 18 The dismounting support 30 further comprises a first guide groove 36 arranged on one side of the nozzle avoiding part 31. When the guide piece 14 of the nozzle assembly 10 is fitted in the first guide groove 36, the nozzle 11 is aligned with the nozzle avoiding part 31. Through the guide cooperation between the first guide groove 36 and the guide piece 14, the positioning and guiding effect during the alignment of the nozzle 11 with the nozzle avoiding part 31 is achieved.

[0063] The assembly relationship between the nozzle assembly 10, the clamping mechanism 20 and the dismounting bracket 30 of the nozzle complete set device 100 of the present application is utilized to realize that the clamping mechanism 20 releases the connected nozzle assembly 10 to the dismounting bracket 30. See Figure 18 , refer to Figure 21 and Figure 23 , the specific process of the clamping mechanism 20 dismounting the nozzle assembly 10 is as follows:

[0064] Step 11: The clamping mechanism 20 carries the connected nozzle assembly 10 to move to the dismounting bracket 30, during which the plurality of clamping claws 22 are clamped on the side of the movable top plate 120 away from the fixed seat 11;

[0065] Step 12: The clamping mechanism 20 carries the connected nozzle assembly 10 to press down to the dismounting bracket 30, the guide 14 of the nozzle assembly 10 is adapted in the first guide groove 36, the nozzle 11 of the nozzle assembly 10 is aligned in cooperation with the nozzle avoiding part 31, the magnetic force piece 35 is fixedly connected with the movable top plate 120, the clamping claws 22 of the clamping mechanism 20 are extruded and opened by the dismounting part 32 of the dismounting bracket 30, specifically, the second guide inclined surface 33 of the dismounting part 32 extrudes the first cooperation inclined surface 221 of the clamping claw 22 and guides the clamping claw 22 to open, and then the clamping claw 22 is buckled on the side of the movable top plate 120 away from the fixed seat 11, so as to release the nozzle assembly 10 from the base 21.

[0066] In step 11 and step 12, the nozzle assembly 10 is a nozzle quick-change material to be cleaned.

[0067] Therefore, through the above design of the nozzle avoiding part 31, the dismounting part 32, the second guide inclined surface 33, the side plane 34, the magnetic force piece 35 and the first guide groove 36 of the dismounting bracket 30, and the assembly design between any one of the dismounting bracket 30 and the clamping claw 22, the movable top plate 120, the first guide inclined surface 122 and the guide 14, the effect of improving the quick dismounting between the nozzle assembly 10 and the clamping mechanism 20 and the quick assembly between the nozzle assembly 10 and the dismounting bracket 30 is realized.

The nozzle mounting portion 41 is used to accommodate the new nozzle assembly 10. The second positioning member 42 is arranged on one side of the nozzle mounting portion 41. The second positioning member 42 is used to be connected with the movable top plate 120, so that the new nozzle assembly 10 is aligned with the nozzle mounting portion 41. The second positioning member 42 plays a role of positioning connection, and is used to realize the installation and positioning of the new nozzle assembly 10 on the nozzle mounting portion 41. The second guide groove 43 is arranged on one side of the nozzle mounting portion 41. When the new nozzle assembly 10 is installed on the nozzle mounting portion 41, the guide member 14 is adapted in the second guide groove 43. The mutual adaptation between the second guide groove 43 and the guide member 14 realizes the accurate positioning between the new nozzle assembly 10 and the mounting bracket 40.

[0070] The assembly relationship between the nozzle assembly 10, the clamping mechanism 20 and the mounting bracket 40 of the nozzle complete device 100 of the present application realizes the purpose that the clamping mechanism 20 loads the new nozzle assembly 10 through the mounting bracket 40. Continued from Figure 20 、 Figure 22 and Figure 23 The specific process that the clamping mechanism 20 installs the new nozzle assembly 10 through the mounting bracket 40 is as follows:

[0071] Step 21: After the original nozzle assembly 10 is released, the clamping mechanism 20 moves above the mounting bracket 40 and presses downward on the mounting bracket 40;

[0072] Step 22: The plurality of clamping claws 22 of the clamping mechanism 20 are pressed by the new nozzle assembly 10. Specifically, the first guide inclined surface 122 of the new nozzle bracket 10 presses and guides the plurality of clamping claws 22 to be mutually opened. With the downward pressing of the clamping mechanism 20, the plurality of clamping claws 22 are clamped on the side of the movable top plate 120 away from the fixed base 11. Then, the plurality of clamping claws 22 cooperatively connect the nozzle assembly 10 to the base 21;

[0073] Step 23: The clamping mechanism 20 carrying the new nozzle assembly 10 rises away from the side of the mounting bracket 40.

[0074] In the above steps 21 to 23, the new nozzle assembly 10 is a cleaned nozzle quick-change material.

[0075] Therefore, through the above design of the nozzle mounting portion 41, the second positioning member 42 and the second guide groove 43 of the mounting bracket 40, and the assembly design between the clamping mechanism 20 and any one of the clamping claw 22, the movable top plate 120, the first guide inclined surface 122 and the guide member 14 of the nozzle assembly 10, the embodiment of the present application realizes the quick installation effect between the new nozzle assembly 10 and the clamping mechanism 20.

[0076] In contrast to the prior art, the present application discloses a nozzle complete set 100. By defining the clamping mechanism 20 to include a base 21 and a plurality of clamping claws 22 movably arranged on the base 21, and defining the clamping mechanism 20 to be pressed downward towards the nozzle assembly 10 so that the plurality of clamping claws 22 are mutually opened under the pressing of the nozzle assembly 10, and then the plurality of clamping claws 22 cooperatively connect the nozzle assembly 10 to the base 21, thereby achieving the purpose of clamping and fixing the nozzle assembly 10 by the plurality of clamping claws 22 of the clamping mechanism 20; and defining the clamping mechanism 20 to be opened by external extrusion, such as the dismounting support 30, to open the plurality of clamping claws 22, so as to release the nozzle assembly 10 from the base 21, thereby achieving the purpose that the plurality of clamping claws 22 of the clamping mechanism 20 can release the nozzle assembly 10 from the base 21 when being extruded and opened, and thus the effect of quick dismounting between the nozzle assembly 10 and the clamping mechanism 20 can be achieved.
