The speed regulating switch valve includes a valve body, a connector, a valve core, a water outlet structure, a T-pin and a handle. When the handle is rotated to a certain state (such as a horizontal state), the first channel and the third channel are directly connected, the second channel and the fourth channel are directly connected, and the material liquid flow rate is the fastest; the rotating handle can be stopped at any other position so that the outlet of the first channel is not directly opposite the inlet of the third channel, and the inlet of the second channel is not directly opposite the outlet of the fourth channel, thereby achieving primary adjustment of the material flow rate; when the material passes through the water outlet structure, due to the reduction in the aperture of the water outlet hole, the material pressure pushes the T-pin in the opposite direction, causing the T-pin to slide along the axial direction of the material outlet channel toward the second channel, so that the distance between the T-pin and the second channel outlet is reduced, and the material flow rate is adjusted again, thereby achieving two adjustments to the material flow rate.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0039] This embodiment provides a speed regulating switch valve to solve the problem of unclear speed regulation in existing switch valves.

[0040] Specifically, if Figures 1 to 3 As shown, the speed regulating switch valve is used to adjust the flow rate of the gas-liquid mixture flowing out of the bubble machine. The speed regulating switch valve includes a valve body 1, a connecting piece 62, a valve core 2, a water outlet structure 3, a T-pin 4 and a handle 5. A cavity 11, a first channel 12 and a second channel 13 are provided in the valve body 1. The cavity 11 is connected to the outside of the valve body 1 through the first channel 12 and the second channel 13 respectively. The outlet end of the second channel 13 is connected to the material outlet channel 14. The inner diameter of the material outlet channel 14 is larger than the inner diameter of the second channel 13; the valve core 2 is rotatably set in the cavity 11, and the outer surface of the valve core 2 is slidably connected to the inner wall of the cavity 11. The valve core 2 opens A third channel 21 and a fourth channel 22 are provided that are interconnected, and when the valve core 2 rotates to the point where the third channel 21 is directly connected to the first channel 12, the fourth channel 22 is directly connected to the second channel 13; the water outlet structure 3 is connected to the outer wall of the second channel 13, and a first through hole and a water outlet hole are provided in the water outlet structure 3. The first through hole is connected to the second channel 13, and the inner diameter of the water outlet hole is smaller than the inner diameter of the second channel 13; the head of the T-pin 4 is slidably connected to the inner wall of the material outlet channel 14, and the tail of the T-pin 4 is gap-fitted with the inner wall of the first through hole; one end of the handle 5 is fixedly connected to the valve core 2 for adjusting the rotation position of the valve core 2.

[0041] Reference Figure 3The material flow rate is adjusted to the highest possible value. The handle 5 can be rotated to any other position, so that the outlet of the first channel 12 is not directly opposite the inlet of the third channel 21, and the inlet of the second channel 13 is not directly opposite the outlet of the fourth channel 22, thereby achieving a primary adjustment of the material flow rate. When the material passes through the water outlet structure 3, the water outlet aperture is reduced, so that the material pressure pushes the T-pin 4 in the opposite direction, causing the T-pin 4 to slide along the axial direction of the material outlet channel 14 toward the second channel 13, thereby reducing the distance between the T-pin 4 and the outlet of the second channel 13 and adjusting the material flow rate again, thereby achieving a secondary adjustment of the material flow rate. In addition, after the primary deceleration, the material passes through the gap between the T-pin 4 and the outlet of the second channel 13. The small gap excites the food-grade gas in the material from the material, further improving the stability of the material flow rate. In other embodiments, when the handle 5 is rotated to a vertical state, the third channel is directly connected to the first channel, and the fourth channel is directly connected to the second channel.

In other embodiments, one of the adapter 61 and the inner wall of the first passage 12 is provided with a slot, and the other is provided with a buckle, and the buckle and the slot are engaged with each other.

[0048] Furthermore, the connecting structure 6 also includes a fifth seal 64, which is interference fit with the adapter 61. The fifth seal 64 is located between the outer wall of the adapter 61 and the inner wall of the first channel 12, limiting the radial displacement of the adapter 61 so that the material flowing out of the bubble machine can accurately flow into the second through hole.

[0053] Optionally, the fixing structure 7 also includes a seventh sealing member 73. The fixing member 71 is provided with a third through hole, and a groove is provided on the wall of the third through hole. The seventh sealing member 73 is located in the groove and has an interference fit with the valve core 2 to prevent the material in the opening cavity from flowing out, and further limit the radial displacement of the fixing member 71, so that the connection between the fixing member 71 and the valve core 2 is more secure.
