In order to prevent the handle 8 from dropping due to its own weight on the long-handle side after the transparent throat 2 is removed and to allow the upper plunger 6 to be driven to slide upward by the short-handle side, a spring seat 11 is mounted above the valve seat 4, and a compression spring 12 is abutted between the spring seat 11 and the upper end of the upper plunger 6.

In order to avoid the situation that the lower plunger 3 is clamped and connected with the upper plunger 6, the lower plunger 3 excessively slides downwards through the upper plunger 6 by the compression spring 12, the first snap ring 13 with the outer diameter larger than the diameter of the discharging channel is annularly arranged on the surface of the plunger at the lower end of the ball head 9, the first snap ring 13 plays a role in limiting the downward sliding stroke of the lower plunger 3, and the lower plunger 3 is convenient to clean the transparent throat seat 2 and the lower plunger 3.

In order to avoid that the upper plunger 6 is pressed by the compression spring 12 to slide downwards excessively when the transparent throat seat 2 and the lower plunger 3 are disassembled and cleaned, the surface of the upper end part of the upper plunger 6 is provided with a second snap ring 14 with the outer diameter larger than the diameter of the sliding hole 5, the bottom of the compression spring 12 is abutted to the top of the second snap ring 14, meanwhile, in order to guide the compression spring 12, the compression spring 12 is prevented from being dislocated in the stress compression process, and the upper plunger 6 upwards extends from the upper end part to form a guide rod 31 with the outer diameter smaller than the outer diameter of the second snap.

In order to select the color and the taste of the ice cream conveniently, the discharging channel comprises a direct current channel 15 corresponding to the mixing drums and a mixing channel 16 corresponding to the mixing drums, the direct current channel 15 is connected with the corresponding mixing drums through a feeding port 17 at the back of the transparent throat seat 2, and the mixing channel 16 is respectively connected with the feeding ports 17 of the two adjacent direct current channels 15 through two material guide pipes 18.

Because the ice cream in the mixing drum, the feeding opening 17 and the material guide pipe 18 can reach higher pressure when the mixing drum is used for mixing, in order to enhance the sealing performance of the direct current channel 15, the mixing channel 16 and the lower plunger 3, avoid the leakage of the high-pressure ice cream from gaps among the lower plunger 3, the direct current channel 15 and the mixing channel 16 and avoid the influence on taste and appearance experience caused by the mixing of two ice creams with different colors in the mixing channel 16, the lower plunger 3 comprises a first lower plunger 19 and a second lower plunger 20 which are respectively installed in the direct current channel 15 and the mixing channel 16 in a sliding manner, first sealing grooves 21 are annularly formed in the surfaces of the first lower plunger 19 above and below the feeding opening 17, and first sealing rubber rings 22 are sleeved in the first sealing grooves 21; the surface of the second lower plug is provided with a second sealing groove 23 which comprises two transverse grooves 24 corresponding to the upper part and the lower part of the discharge end of the material guide pipe 18 and two vertical grooves 25 communicated with the two transverse grooves 24, the two vertical grooves 25 and the discharge end of the material guide pipe 18 are arranged in a staggered manner, an I-shaped sealing rubber ring 26 is sleeved in the second sealing groove 23, flowing ice cream flowing into a gap between the second lower plunger 20 and the mixing channel 16 from the material guide pipes 18 on the two sides of the mixing channel 16 is blocked by the I-shaped sealing rubber ring 26, and the flowing ice cream is prevented from being tainted by mixing.

Meanwhile, in order to improve the sealing performance between the transparent throat seat 2 and the mixing drum, a second sealing rubber ring 32 is arranged between the transparent throat seat 2 and the mixing drum.

In order to enable ice cream to smoothly flow into the feeding port 17 from the inside, the feeding port 17 is generally large in opening, the first lower plunger 19 slides up and down and can slide in a deviation manner at the feeding port 17, the deviation sliding enables the edge of the feeding port 17 to rub two first sealing rubber rings 22, so that the first sealing rubber rings 22 are abraded due to friction, the sealing performance and the service life are affected, a vertical guide column 27 used for being in sliding contact with the first sealing rubber rings 22 is arranged on the inner wall surface of the feeding port 17 along the direct current channel 15, when the first lower plunger 19 slides up and down and the two first sealing rubber rings 22 pass through the feeding port 17, the vertical guide column 27 can effectively and slidably contact with the first sealing rubber rings 22, so that the first lower plunger 19 vertically slides up and down, the abrasion of the two first sealing rubber rings 22 caused by the sliding deviation of the first lower plunger 19 is reduced, and the sealing performance of the first sealing rubber rings 22 is improved.

In order to enable the ice cream in the material guide pipe 18 to flow back to the mixing drum and avoid the ice cream from staying in the material guide pipe 18 for a long time and being melted by the external temperature, the ice cream mixer is further provided with a material return pipe 28, one end of the material return pipe is communicated with the material guide pipe 18, the other end of the material return pipe 28 is communicated with the discharge end of the mixing drum, the pipe diameter of the material return pipe 28 is smaller than that of the material guide pipe 18, and the ice cream at the discharge end of the mixing drum can smoothly flow to the material return pipe 28 and flow back to the mixing drum along the material guide pipe 18 due to the fact that the.

In order to enrich the shape of the ice cream bar flowing out from the bottom ends of the direct flow channel 15 and the mixing channel 16, the bottom parts of the direct flow channel 15 and the mixing channel are embedded with discharging nozzles 7 with discharging holes 33 of different shapes.
