[0038] Example 1

[0039] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a slider-free, easy-to-clean decorating valve holder, including:

[0040] The mounting mechanism 1 includes a mounting base 11 and mounting support plates 12 fixed to the top of both sides of the mounting base 11;

[0041] The drive mechanism 2 includes a rotating rod 22 rotatably mounted on the top of the two mounting plates 12, a moving block 23 rotatably mounted on the surface of the rotating rod 22, and a first gear 26 rotatably mounted on the outer side of the top of the moving block 23 for adjusting the tilt angle of the decorating valve.

[0042] The fixed installation mechanism 3 includes a mounting column 32 that rotates through the bottom of the side of the movable block 23, a fixing plate 31 fixed to the inner end of the mounting column 32, a connecting plate 34 fixedly connected to both ends of the inner side of the fixing plate 31 and used for positioning and installing the decorating valve, and a snap-fit ​​mechanism 4 snap-fit ​​connected to the outer side of the connecting plate 34 and used for quick disassembly and installation of the decorating valve.

[0043] The decorating valve mechanism 6 includes a decorating valve cylinder 61 positioned between the outer ends of two connecting plates 34, a connecting block 63 fixed between the two sides of the decorating valve cylinder 61, an insertion hole 62 opened in the middle of the connecting block 63, and a pushing mechanism 5 installed at the top of the decorating valve cylinder 61.

[0044] The device incorporates a rotating rod 22 and a moving block 23 between the mounting support plates 12. The decorating valve cylinder 61 is rotatably mounted on one side of the moving block 23 via a connecting block 63, a connecting plate 34, a fixing plate 31, and a mounting column 32. Therefore, rotating the rotating rod 22 can drive the decorating valve cylinder 61 to move to different positions. The first gear 26 meshes with the second gear 33 to rotate and adjust the tilt angle of the decorating valve cylinder 61, facilitating flexible adjustment and use of the decorating valve.

[0045] By fixing connecting blocks 63 on both sides of the decorating valve cylinder 61, and connecting blocks 63 being connected to connecting plate 34 via snap-fit ​​rod 41, it is easy to quickly disassemble and clean the decorating valve cylinder 61. Moreover, inside the decorating valve cylinder 61, piston rod 54 and piston plate 52 are installed via detachable cylinder cover 51, and ejector rod 53 is fixed at the bottom of piston plate 52, which facilitates the full ejection of raw materials inside the decorating valve cylinder 61. Therefore, it is easy to disassemble, install, and clean the decorating valve.

[0046] Specifically, the snap-fit ​​mechanism 4 includes a snap-fit ​​rod 41 snap-fitted to the outside of the connecting block 63 and the connecting plate 34, a limiting plate 43 fixedly connected to the outer end of the snap-fit ​​rod 41, and a tension spring 42 sleeved on the outer end of the surface of the snap-fit ​​rod 41.

[0047] Specifically, by elastically setting a snap-fit ​​rod 41 on the outside of the connecting block 63, the snap-fit ​​rod 41 snaps into the connection between the connecting block 63 and the connecting plate 34, thus stably snapping the decorating valve cylinder 61 into place. By pulling the snap-fit ​​rod 41 and the tension spring 42 outward by the limiting plate 43, the connecting plate 34 can be pulled out of the insertion hole 62 inside the connecting block 63, and the decorating valve cylinder 61 can be disassembled.

[0049] The cap 51 is detachably and securely connected to the top of the decorating valve cylinder 61, which facilitates opening the decorating valve cylinder 61 for disassembly and cleaning, and also facilitates cleaning the piston rod 54 and piston plate 52.

[0050] Preferably, the mounting plate 12 is vertically arranged, the rotating rod 22 is horizontally arranged, and a first motor 21 is installed at one end of the rotating rod 22. The first motor 21 is fixedly installed on the outer top of the mounting plate 12. A first rotating hole 24 is opened at the top of the surface of the moving block 23. The first rotating hole 24 is a threaded hole structure. The rotating rod 22 is a threaded rod structure, and the thread rotates through the first rotating hole 24. A guide rod 28 is fixed between the two mounting plates 12 and below the rotating rod 22, which slides through the moving block 23.

[0051] The movable block 23 is a rectangular plate structure and is vertically arranged. A second motor 27 is fixedly installed at its top. A first gear 26 is fixedly installed on the conveying end surface of the side of the second motor 27. The first gear 26 is vertically arranged. A second rotating hole 25 is opened at the bottom of the side of the movable block 23. The outer end of the mounting column 32 slides through the second rotating hole 25 and a second gear 33 is fixed at the outer end. The second gear 33 is vertically arranged and meshes with the bottom end of the first gear 26.

[0052] The first motor 21 drives the rotating rod 22 to rotate, which in turn drives the moving block 23 to move on the surface of the guide rod 28, thereby moving the decorating valve to different positions for use. In addition, the second motor 27 drives the first gear 26 to rotate, and the first gear 26 meshes with and drives the second gear 33 to rotate, which in turn drives the mounting column 32, the fixing plate 31, the connecting plate 34 and the decorating valve cylinder 61 to rotate, thereby adjusting the tilt angle of the decorating valve and making it easier to use the decorating valve flexibly.

[0053] Preferably, the mounting post 32 is horizontally set, the fixing plate 31 and the connecting plate 34 are both rectangular plate structures and are both horizontally set, the outer end of the connecting plate 34 slides through the insertion hole 62, the outer end surface of the connecting plate 34 has a first snap-fit ​​hole 35, the outer middle of the insertion hole 62 has a second snap-fit ​​hole 64, the inner end of the snap-fit ​​rod 41 slides through the second snap-fit ​​hole 64 and inserts into the first snap-fit ​​hole 35, the snap-fit ​​rod 41 is horizontally set, and the two ends of the tension spring 42 are respectively connected to the inner side of the limiting plate 43 and the outer side of the connecting block 63.

[0054] The snap-fit ​​rod 41 is snapped into place between the connecting plate 34 and the connecting block 63, which facilitates quick disassembly and installation of the decorating valve cylinder 61.

[0055] It should be noted that the outer top of the decorating valve cylinder 61 has an external threaded surface, and the inner surface of the cylinder cover 51 has an internal threaded surface. The cylinder cover 51 and the decorating valve cylinder 61 are connected by a threaded fit. A lifting hole 55 is opened in the middle of the cylinder cover 51. The piston rod 54 slides through the lifting hole 55. The cross-section of both the lifting hole 55 and the piston rod 54 is rectangular. The piston plate 52 is tightly slidably inserted into the interior of the decorating valve cylinder 61. Its bottom end is fixed with an ejector rod 53 for fully ejecting the raw materials inside the decorating valve.

[0056] The push-pull bar 57 is perpendicular to the piston rod 54, and the electric push rod 56 is parallel to the piston rod 54, with its top end fixed to the top end of the cylinder cover 51.

[0057] The electric push rod 56 drives the piston rod 54 and piston plate 52 to slide tightly inside the decorating valve cylinder 61, pushing the raw material out of the decorating valve. In addition, the ejector rod 53 can fully eject the raw material at the bottom of the decorating valve cylinder 61, reducing the amount of raw material remaining inside the decorating valve cylinder 61 and making it easier to clean the decorating valve.

[0058] In use, a rotating rod 22 and a moving block 23 are set between the mounting support plates 12, and the decorating valve cylinder 61 is rotatably mounted on one side of the moving block 23 through the connecting block 63, the connecting plate 34, the fixing plate 31 and the mounting column 32. The first motor 21 drives the rotating rod 22 to rotate, driving the moving block 23 to move on the surface of the guide rod 28, thereby moving the decorating valve to different positions for use.

[0059] The second motor 27 drives the first gear 26 to rotate, and the first gear 26 meshes with and drives the second gear 33 to rotate, which in turn drives the mounting column 32, the fixing plate 31, the connecting plate 34 and the decorating valve cylinder 61 to rotate, thereby adjusting the tilt angle of the decorating valve and making the decorating valve easy to use.

[0060] Furthermore, the snap-fit ​​rod 41 snaps into the connection between the connecting block 63 and the connecting plate 34, thus ensuring a stable snap-fit ​​installation of the decorating valve cylinder 61. By pulling the snap-fit ​​rod 41 and the tension spring 42 outward through the limiting plate 43, the connecting plate 34 can be pulled out of the insertion hole 62 inside the connecting block 63, allowing the decorating valve cylinder 61 to be disassembled.

[0061] Additionally, the cap 51 is detachably and securely connected to the top of the decorating valve cylinder 61, and the electric push rod 56 drives the piston rod 54 and piston plate 52 to slide tightly inside the decorating valve cylinder 61, pushing the raw material out of the decorating valve.

[0062] Moreover, the ejector rod 53 can fully eject the material from the bottom of the decorating valve cylinder 61, reducing the amount of material remaining inside the decorating valve cylinder 61, making it easier to open the decorating valve cylinder 61 for disassembly and cleaning, and also making it easier to clean the piston rod 54 and piston plate 52.

[0063] In summary, by setting a rotating rod 22 and a moving block 23 between the mounting support plates 12, and by rotatably mounting the decorating valve cylinder 61 on one side of the moving block 23 via the connecting block 63, connecting plate 34, fixing plate 31 and mounting column 32, the decorating valve cylinder 61 can be moved to different positions by rotating the rotating rod 22, and the tilt angle of the decorating valve cylinder 61 can be adjusted by the first gear 26 meshing with the second gear 33, making it easy to flexibly adjust and use the decorating valve.

[0064] By fixing connecting blocks 63 on both sides of the decorating valve cylinder 61, and connecting blocks 63 being connected to connecting plate 34 via snap-fit ​​rod 41, it is easy to quickly disassemble and clean the decorating valve cylinder 61. Moreover, inside the decorating valve cylinder 61, piston rod 54 and piston plate 52 are installed via detachable cylinder cover 51, and ejector rod 53 is fixed at the bottom of piston plate 52, which facilitates the full ejection of raw materials inside the decorating valve cylinder 61. Therefore, it is easy to disassemble, install, and clean the decorating valve.
