The box body 410 is not directly connected with the inner container 220, so that the box body 410 is prevented from being worn due to frequent contact connection between the box body 410 and the inner container 220.
Referring to fig. 11, the cassette 410 is slidably coupled to the mounting base 470 in a horizontal direction to facilitate the taking and placing of the cassette 410.
Specifically, the mounting seat 470 has a bottom surface 471, side walls are disposed on the left side, the right side and the rear side of the bottom surface 471, the front side of the bottom surface 471 is open and has no side wall, the box body 410 is placed on the bottom surface 471, and the open structure on the front side of the bottom surface 471 facilitates the insertion and removal of the box body 410.
A certain gap is formed between the sidewall of the mounting seat 470 and the box body 410, so that the box body 410 can be smoothly placed, and friction between the box body 410 and the sidewall can be avoided. Referring to fig. 12, a second protrusion 4711 is disposed on a bottom surface 471 of the mounting seat 470, which contacts the cartridge 410, the cartridge 410 (specifically, a bottom surface of the lower cartridge 412) is correspondingly provided with a second recess 418, the second protrusion 4711 is located in the second recess 418, and by the cooperation between the second protrusion 4711 and the second recess 418, the positioning of the cartridge 410 on the mounting seat 470 is realized, so as to prevent the cartridge 410 from moving or sliding off the mounting seat 470.
The outer perimeter of the second raised portion 4711 is spaced from the inner perimeter of the second recessed portion 418 by a gap, such as 3-5mm, that allows the cartridge 410 to be moved a small amount from the mounting block 470 to adjust the position of the cartridge 410 to facilitate easy access of the tip assembly 421 when the tip assembly 421 is attached to the cartridge 410.
The mounting seat 470 and the inner container 220 are detachably connected by means of splicing, third splicing parts 472 are respectively arranged on the left side wall and the right side wall of the mounting seat 470, second splicing parts 221 are correspondingly arranged on the inner container 220 of the door body, and the third splicing parts 472 are detachably spliced with the second splicing parts 221.
The third inserting portion 472 and the second inserting portion 221 are both inserting structures extending along the vertical direction, the mounting seat 470 and the inner container 220 are inserted and fixed along the vertical direction, and the box body 410 is in horizontal sliding contact with the mounting seat 470 when being taken or placed, so that the influence on the connection between the mounting seat 470 and the inner container 220 when the box body 410 is taken or placed can be avoided.
Referring to fig. 11, the third mating portion 472 includes a third mating rib 4721 and third recesses 4722 disposed on left and right sides of the third mating rib 4721, and a lower portion of the third recess 4722 is open to facilitate mating with the second mating portion 221; referring to fig. 9, the second socket 221 includes two first protrusions 2211 corresponding to the third recesses 4722, and a socket gap 2212 is formed between the two first protrusions 2211; when the mounting seat 470 is assembled, the third concave portion 4722 is matched with the first convex portion 2211, the first convex portion 2211 is inserted into the third concave portion 4722 from bottom to top, and the third plugging rib 4721 is inserted into the plugging gap 2212 from top to bottom, so that the connection between the mounting seat 470 and the liner 220 is realized, the plugging action is simple, and the structure is reliable.
The third inserting portion 472 is arranged to be a concave portion and convex rib structure, the outer side surface of the third inserting rib 4721 and the outer side surface of the mounting seat 470 are located on the same plane, and therefore the overall outer contour of the mounting seat 470 does not have an obvious protruding structure, and when the mounting seat 470 is moved, foreign objects can be prevented from being scraped to the third inserting portion 472, so that the third inserting portion 472 is broken and fails, and the assembly between the mounting seat 470 and the liner 220 is affected.
At least one surface of the matching surface of the third inserting-connecting part 472 and the second inserting-connecting part 221 is provided with a wave clamping groove 450, so that the connection reliability between the third inserting-connecting part 472 and the second inserting-connecting part 221 is improved.
The wave locking groove 450 also has the function that the installation height of the installation seat 470 can be adjusted through the wave locking groove 450, so that the suction head assembly 421 can be smoothly butted with the suction head connection part 414, and the phenomenon that the pipeline 422 is stretched or bent due to improper height of the installation seat 470 is avoided.
The number of the wave slots 450 is not too large, so as to avoid affecting the convenient insertion between the third insertion portion 472 and the second insertion portion 221.
In some embodiments of the present application, the wave locking grooves 450 are respectively formed on the side of the third inserting rib 4721 facing the one of the third concave portions 4722, the side of the one of the first convex portions 2211 facing the inserting gap 2212, and the wall of the liner 220 at the inserting gap 2212.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
