[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Directional terms mentioned in this invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only used with reference to the directions of the drawings. The directional terms used are used to illustrate and understand the invention, and are not intended to limit the invention.

[0030] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.

[0031] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two components or an interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0032] Existing rotary valves feature a shared volume chamber, connecting the input and output ports. All fluids flow through and are stored within this shared volume chamber. However, over time, some fluids can deteriorate. For example, when a rotary valve is used in an automatic cooking machine, various seasonings can easily mix and remain in the volume chamber. Over time, this can breed bacteria and cause mold, potentially impacting human health.

[0033] In addition, since the stepper motor does not have a signal feedback device like the servo motor, when the motor gets stuck and loses steps during rotation, the motor will have inaccurate positioning problems, which will affect the docking of the input hole and the output hole and affect the normal use of the rotary cutting valve.

[0034] The following is a first embodiment of a multi-channel rotary cutting valve with independent water outlet pipes provided by the present invention, which can solve the above technical problems.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 In the figures, units with similar structures are represented by the same reference numerals.

[0036] This embodiment provides a multi-channel rotary cutting valve with independent water outlet pipes, which includes: a valve housing 11, a rotary drive mechanism 12, a rotary shaft 13, a connecting pipe 16, a rotary cutting piece 15, and an elastic member 17.

[0037] A rotating shaft 13 rotates and extends through the valve housing 11. One end of the rotating shaft 13 is connected to the output end of the rotary drive mechanism 12. The other end of the rotating shaft 13 is provided with an output hole 131 that connects the interior and exterior spaces of the valve housing 11. The valve housing 11 is provided with multiple input holes 141 that connect the interior and exterior spaces of the valve housing 11. The rotary drive mechanism 12 can be a motor that drives the rotating shaft 13 to rotate.

[0038] The rotary section 15 and connecting pipe 16 are located within the valve housing 11. The rotary section 15 is slidably mounted on the outer periphery of the rotating shaft 13 and is in transmission engagement with the rotating shaft 13, rotating synchronously with the rotating shaft 13. The rotary section 15 covers multiple input holes 141 and is provided with a transfer hole 151. The connecting pipe 16 connects one end of the transfer hole 151 to the output hole 131, and the other end of the transfer hole 151 connects to the input hole 141. Rotation of the rotary section 15 causes the transfer hole 151 to switch between connecting with different input holes 141, thereby switching different input holes 141 to communicate with the output hole 131. Fluid can be fully discharged through the connecting pipe 16, reducing residual fluid and minimizing bacterial growth and mold.

[0039] A stopper protrusion 132 is provided on the outer circumference of the rotating shaft 13. An elastic member 17 is positioned between the stopper protrusion 132 and the side of the rotating section 15 facing away from the input hole 141. This elastic member 17 compresses the rotating section 15, ensuring that it closes the remaining input holes 141 not connected to the transfer hole 151. In this embodiment, the elastic member 17 is a spring. The rotating section 15 comprises a plate and a column, and the elastic member 17 is positioned around the outer circumference of the column.

[0040] Please refer to Figure 3 Optionally, the output hole 131 includes an axial hole section 1311 parallel to the axis of the rotating shaft 13, and a radial hole section 1312 perpendicular to the axis of the rotating shaft 13. The connecting pipe 16 is a hose, and the connecting pipe 16 connects the axial hole section 1311 and the transfer hole 151 by bending.

[0041] It should be noted that in this embodiment, the output hole 131, the input hole 141 and the transfer hole 151 are all extended with a tube body, which is convenient for connecting with the corresponding connecting pipe, input pipe, or output pipe. The radial hole section 1312 is located in the tube body of the output hole 131.

[0042] Please refer to Figure 4Optionally, an L-shaped protruding tube 133 protrudes from one side of the rotating shaft 13. The output hole 131 includes a first axial hole segment 1311 and a second axial hole segment 1313 parallel to the axis of the rotating shaft 13, and a radial hole segment 1312 perpendicular to the axis of the rotating shaft 13. The first axial hole segment 1311 is located within the rotating shaft 13, and the second axial hole segment 1313 is located within the protruding tube 133. The radial hole segment 1312 connects between the first axial hole segment 1311 and the second axial hole segment 1313. The second axial hole segment 1313 is opposite the transfer hole 151, and the connecting tube 16 connects the second axial hole segment 1313 and the transfer hole 151. In this way, the connecting tube 16 can connect the output hole 131 and the transfer hole 151 without bending.

[0043] Please refer to Figure 1 In this embodiment, a plurality of input holes 141 are provided at one end of the valve housing 11 away from the rotary drive mechanism 12 , and the axes of the input holes 141 are parallel to the axis of the rotating shaft 13 .

[0044] Among them, the valve housing 11 includes a main shell and a valve cover 14 (the reference numeral 11 also refers to the main shell). One end of the main shell is an opening, and the valve cover 14 is closed and arranged on the opening. The output hole 131 and multiple input holes 141 are located on the end face of the valve cover 14, and the multiple input holes 141 are distributed in a ring around the output hole 131.

[0045] Please refer to Figure 2 and Figure 3 In this embodiment, the multi-channel rotary cutting valve with independent water outlet pipes also includes a water pass plate 18, which is arranged between the rotary cutting piece 15 and the inner wall of the valve housing 11 where the input hole 141 is located. The water pass plate 18 is provided with first through holes 181 corresponding to the multiple input holes 141 one by one. The rotary cutting piece 15 and the water pass plate 18 are made of ceramic material, preferably a high-hardness and high-wear-resistant ceramic material, which can well ensure the sealing of the rotary cutting part. The rotary switching life of the rotary cutting piece 15 and the water pass plate 18 is long and will not rust.

[0046] Furthermore, a sealing gasket 19 is provided between the water-passing plate 18 and the inner wall of the valve housing 11 where the input holes 141 are located. The sealing gasket 19 is provided with second through holes 191 corresponding to the plurality of input holes 141 on a one-to-one basis.

[0047] Please refer to Figure 2In this embodiment, a microswitch 1A is mounted on the inner wall of the valve housing 11, and a lever 1B is fixedly connected to the rotary shaft 13. The microswitch 1A is located along the rotational trajectory of the lever 1B. Before each rotation of the rotary section 15 switches to another input port 141 for docking, the rotary shaft 13 rotates, driving the lever 1B. This squeezes and triggers the microswitch 1A. At this point, the host control board receives a signal indicating that the rotary drive mechanism 12 has returned to its origin, thus calibrating the origin. After calibration, the rotary drive mechanism 12 can accurately drive the rotary section 15 to the desired position, eliminating errors during multiple rotary rotations. This ensures that the transfer port 151 precisely docks with the input port 141, ensuring stable fluid delivery.

[0048] The working principle of the multi-channel rotary cutting valve with independent water outlet pipes in this embodiment is as follows: the rotary drive mechanism 12 drives the rotary shaft 13 to rotate, and the rotary shaft 13 drives the rotary cutting section 15 to rotate, so that the transfer hole 151 switches to dock with different input holes 141, thereby switching different input holes 141 to connect with the output hole 131, and the fluid is transported between the transfer hole 151 and the output hole 131 through the connecting pipe 16 to realize multi-channel switching.

[0049] Before each peeling, the rotary drive mechanism 12 drives the rotating shaft 13 to rotate and drives the lever 1B to rotate until it contacts the micro switch 1A to calibrate the initial position. After calibration, the peeling section 15 rotates to the required position.

[0050] The following is a second embodiment of a multi-channel rotary cut valve with independent water outlet lines, which solves the above technical problems. The main difference between the second embodiment and the first embodiment lies in the different placement of the input holes. The remaining structural principles are essentially the same, and the common parts will not be further described in this embodiment. The following mainly describes the placement of the input holes in the second embodiment.

[0051] Please refer to Figure 5-Figure 7 This embodiment provides a multi-channel rotary cutting valve with independent water outlet pipes, which includes: a valve housing 11, a rotary drive mechanism 12, a rotating shaft 13, a connecting pipe 16, a rotary cutting piece 15, and an elastic member 17.

[0052] A rotating shaft 13 rotates and extends through the valve housing 11. One end of the rotating shaft 13 is connected to the output end of the rotary drive mechanism 12. The other end of the rotating shaft 13 is provided with an output hole 131 that connects the interior and exterior spaces of the valve housing 11. The valve housing 11 is provided with multiple input holes 141 that connect the interior and exterior spaces of the valve housing 11. The rotary drive mechanism 12 can be a motor that drives the rotating shaft 13 to rotate.

[0053] The rotary section 15 and the connecting pipe 16 are located in the valve housing 11. The rotary section 15 is slidably sleeved on the outer periphery of the rotating shaft 13, and the rotary section 15 and the rotating shaft 13 are in transmission cooperation. The rotary section 15 and the rotating shaft 13 rotate synchronously. The rotary section 15 covers multiple input holes 141. A transfer hole 151 is provided on the rotary section 15. The connecting pipe 16 connects one end of the transfer hole 151 and the output hole 131, and the other end of the transfer hole 151 is connected to the input hole 141. The rotation of the rotary section 15 causes the transfer hole 151 to switch to dock with different input holes 141, thereby switching different input holes 141 to be connected with the output hole 131.

[0054] A stopper protrusion 132 is provided on the outer circumference of the rotating shaft 13. An elastic member 17 is positioned between the stopper protrusion 132 and the side of the rotating section 15 facing away from the input hole 141. This elastic member 17 compresses the rotating section 15, ensuring that it closes the remaining input holes 141 not connected to the transfer hole 151. In this embodiment, the elastic member 17 is a spring. The rotating section 15 comprises a plate and a column, and the elastic member 17 is positioned around the outer circumference of the column.

[0055] Please refer to Figure 5 and Figure 6 In this embodiment, a plurality of input holes 241 are provided on the circumferential side of the valve housing 11 close to one end of the rotary drive mechanism 12 , and the axes of the input holes 241 are perpendicular to the axis of the rotary shaft 13 .

[0056] Specifically, the valve housing 11 includes a main body and a valve cover 24. The main body has an opening at one end, and the valve cover 24 is disposed to seal the opening. Multiple input holes 241 are disposed on the circumferential side of the valve cover 24. In combination with the input holes 141 in the first embodiment, the multi-channel rotary cut valve with independent water outlet pipes of the present invention can be provided with input holes in different positions to meet different user needs.

[0057] The rotary drive mechanism 12 is located on the side of the valve cover 24 away from the main housing, and the rotary drive mechanism 12 is connected to the valve cover 24 through the bracket 21. Figure 7 The lever 1B and the micro switch 1A are arranged between the bracket 12 and the valve cover 24.

[0058] The multi-channel rotary cutting valve with independent water outlet pipes of the utility model is connected to the output hole and the transfer hole by arranging a connecting pipe in the valve shell. The fluid can be better and completely output through the connecting pipe, which reduces residue and reduces bacterial growth and mildew.

[0059] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
