[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figure 1-5 A spray gun connection assembly for a cleaning machine includes: a cleaning machine connection pipe 1, a spray gun body 5, and a connection component 4. One end of the cleaning machine connection pipe 1 is connected to the cleaning machine, and a handheld component is provided on the outside of the cleaning machine connection pipe 1; the connection component 4 is used to connect the spray gun body 5 to the cleaning machine connection pipe 1, and the other end of the cleaning machine connection pipe 1 is connected to the connection component 4.
[0036] The connecting component 4 includes a connecting ring 8, which is disposed between the spray gun body 5 and the cleaning machine connecting pipe 1; a plug 6, which is symmetrically disposed on the side wall of the spray gun body 5 that contacts the connecting ring 8; and a plug-in module for plugging and fixing the plug 6.
[0037] The above design connects the spray gun body 5 and the cleaning machine connecting pipe 1 by setting the connecting component 4. The insert 6 set on the side wall of the spray gun body 5 is inserted into the insertion hole 22 opened on the side wall of the connecting ring 8. The insertion hole 22 is provided with a plug-in module for fixing the insert 6, which makes it easier for users to install and disassemble the spray gun body 5.
[0038] Specifically, both sets of insert posts 6 have slots 7 on their outer arc surfaces that correspond to the locking blocks 12. A drainage hole 20 is provided in the middle of the side wall of the connecting ring 8, and an insertion hole 22 corresponding to the insert post 6 is provided outside the drainage hole 20. In this design, the slots 7 on the outer arc surfaces of the insert posts 6 are used to insert the insertion module into the slots 7 to fix the insert posts 6. Furthermore, the mounting cavity 21 is equipped with a disassembly structure that facilitates the disassembly of the spray gun body 5 by the user, allowing for faster disassembly and replacement of the spray gun body 5.
[0039] Specifically, the plug-in module includes a locking block 12, which is symmetrically arranged inside the insertion hole 22 opened on the side wall of the connecting ring 8. The locking blocks 12 are respectively arranged on the opposite side walls of the fixing frame 11. The insertion hole 22 and the mounting cavity 21 are interconnected. The mounting cavity 21 is provided with a disassembly structure to facilitate the user to disassemble the spray gun body 5.
[0040] The above design involves symmetrically setting the locking blocks 12 inside the insertion holes 22 on the side wall of the connecting ring 8, and the two sides inside the insertion holes 22 are provided with mounting cavities 21 inside the connecting ring 8. The locking blocks 12 are respectively set on the opposite side walls of the fixing frame 11, and the fixing frame 11 is placed inside the mounting cavity 21. The fixing frame 11 is driven by the disassembly structure to move the locking blocks 12 away from the inside of the locking slot 7 on the outer arc surface of the insertion post 6, which makes it convenient for the user to disassemble and replace the spray gun body 5.
[0041] Conversely, when the spray gun body 5 needs to be installed, the user presses the disassembly structure to make the fixing bracket 11 leave the inside of the insertion hole 22, so that the insertion post 6 provided on the side wall of the spray gun body 5 can be inserted into the inside of the insertion hole 22. After the insertion post 6 is inserted into the inside of the insertion hole 22, the user releases the hand, and the disassembly structure drives the locking block 12 on the side wall of the fixing bracket 11 to insert into the inside of the locking slot 7, thus completing the installation of the spray gun body 5.
[0042] Specifically, the disassembly structure includes a pressing column 16, the end of which passes through the side wall of the connecting ring 8 and connects to an L-shaped frame 15 inside the mounting cavity 21. A spring 17 is provided between the side wall of the L-shaped frame 15 and the inner wall of the mounting cavity 21. A gear 14 is rotatably disposed inside the mounting cavity 21 and located between the L-shaped frame 15 and the fixed frame 11. Toothed plates 13 are provided on the opposite side walls of the L-shaped frame 15 and the fixed frame 11. The toothed plates 13 on the side walls of the L-shaped frame 15 and the fixed frame 11 are meshed with the gear 14. A filter screen 9 is provided inside the connecting ring 8. A cleaning strip 10 for scraping off impurities on the surface of the filter screen 9 is rotatably disposed in the middle of the side wall facing the cleaning machine connecting pipe 1.
[0043] In the above design, a gear 14 is rotatably installed inside the mounting cavity 21. Simultaneously, the ends of the pressing posts 16 penetrate the side walls of the connecting ring 8 and connect to the L-shaped frame 15 inside the mounting cavity 21. The outer side walls of the L-shaped frame 15 are connected to the inner wall of the mounting cavity 21 via springs 17. Furthermore, toothed plates 13 are provided on the opposite side walls of the L-shaped frame 15 and the fixed frame 11. The toothed plates 13 on the opposite side walls of the L-shaped frame 15 and the fixed frame 11 mesh with the gear 14. When the user needs to spray... When the gun body 5 is disassembled and replaced, the pressing column 16 is pressed, which compresses the spring 17 and drives the L-shaped frame 15 to move into the mounting cavity 21. At this time, the toothed plate 13 on the side wall of the L-shaped frame 15 drives the gear 14 to rotate. The gear 14 further drives the toothed plate 13 on the side wall of the fixing frame 11 to move, thereby causing the fixing frame 11 to drive the locking block 12 to leave the inside of the locking slot 7 on the outer arc surface of the insert 6. At this time, the spray gun body 5 is pulled out from the side wall of the connecting ring 8, thus realizing the disassembly of the spray gun body 5.
[0044] Specifically, the spray gun body 5 is provided with an outer insert ring 23 and an inner insert ring 24 on the side wall facing the connecting ring 8. The side wall of the connecting ring 8 is provided with an outer slot 18 and an inner slot 19 corresponding to the outer insert ring 23 and the inner insert ring 24. A sealing ring is provided inside the outer slot 18 and the inner slot 19.
[0045] The above design features an outer insert ring 23 and an inner insert ring 24 on the sidewall of the spray gun body 5 facing the connecting ring 8. The outer insert ring 23 and the inner insert ring 24 are respectively inserted into the outer slot 18 and the inner slot 19 opened on the sidewall of the connecting ring 8. The outer slot 18 and the inner slot 19 are provided with sealing rings. The outer insert ring 23 and the inner insert ring 24 are respectively inserted into the outer slot 18 and the inner slot 19 to ensure the sealing between the spray gun body 5 and the connecting ring 8 during installation, thereby further ensuring the performance of the spray gun body 5.
[0046] Specifically, the handheld component includes a fixing sleeve 2, which is fixedly fitted onto the outside of the cleaning machine connecting pipe 1. A handle 3 is provided at the bottom of the fixing sleeve 2. The cleaning machine connecting pipe 1 is threadedly connected to the connecting ring 8. This design allows the user to easily connect the cleaning machine connecting pipe 1 by holding the fixing sleeve 2, rotating the threaded connection between the cleaning machine connecting pipe 1 and the connecting ring 8, and then rotating the pipe.
[0047] Working principle: In use, after the cleaning machine connecting pipe 1 is threadedly connected to the connecting ring 8, the user presses the pressing post 16 by hand to move the locking block 12 on the side wall of the fixing bracket 11 away from the inside of the insertion hole 22 and into the installation cavity 21. The insertion post 6 on the side wall of the spray gun body 5 is inserted into the insertion hole 22 on the side wall of the connecting ring 8. After insertion, the pressing post 16 is released. Under the elastic force stored in the spring 17, the fixing bracket 11 drives the locking block 12 to be inserted into the locking slot 7 on the outer arc surface of the insertion post 6, so as to realize the installation of the spray gun body 5. The outer insertion ring 23 and the inner insertion ring 24 are inserted into the outer slot 18 and the inner slot 19 on the side wall of the connecting ring 8 to ensure the sealing between the spray gun body 5 and the connecting ring 8 during installation.
