[0024] Reference Figure 1As shown, the rotary sealed evaporator for the snow ice machine according to the embodiment of the present invention includes an evaporator roller body 100, a bearing seat 200, an air intake rod 300 and a sealing member 300. The present invention is provided with a sealing member 300. In order to prevent the refrigerant inside the evaporator roller body 100 from leaking from the gap between the bearing seat 200 and the air intake rod 300, the left side of the bearing seat 200 is connected to the evaporator roller body 100, and the bearing seat 200 has a mounting cavity 210. The air intake rod 300 is located in the mounting cavity 210 and is rotatably connected to the bearing seat 200. The inner wall of the mounting cavity 210 includes an abutment wall 211 extending in the front-to-back direction; the air intake rod 300 00 has a protrusion 310 located in the installation cavity 210, and the abutment wall 211 and the protrusion 310 are spaced apart along the left-right direction; the sealing component 300 is located between the outer wall of the intake rod 300 and the inner wall of the installation cavity 210, and the sealing component 300 includes two pressure covers 310 spaced apart along the left-right direction and movable left-right and an elastic member 320 located between the two pressure covers 310, and the two pressure covers 310 are both provided with a first sealing member 330 on the side away from the elastic member 320, one of the first sealing members 330 can abut against the abutment wall 211, and the other first sealing member 330 can abut against the side of the protrusion 310 close to the abutment wall 211.

[0025] By arranging an elastic member 320, two pressure covers 310 and two first sealing members 330 between the air intake rod 300 and the bearing seat 200, the two pressure covers 310, under the action of the elastic member 320, drive the two first sealing members 330 to abut against the abutment wall 211 and the side wall of the protrusion 310 respectively, and then the first sealing member 330 located on the left, driven by the pressure cover 310, performs a first seal on the space between the air intake rod 300 located at the abutment wall 211 and the bearing seat 200, and the first sealing member 330 located on the right, driven by the pressure cover 310, performs a second seal on the space between the air intake rod 300 located at the protrusion 310 and the bearing seat 200, thereby achieving a good sealing effect; when the refrigerant inside the evaporator roller body 100 enters the installation cavity 210 from the left end of the bearing seat 200, due to the provision of the first seal and the second seal, even if the first seal fails, there is still a second seal to seal and avoid refrigerant leakage.

[0026] In some embodiments of the present invention, Figure 1 、 2As shown, the installation cavity 210 includes a first cavity 212 and a second cavity 213 located on the right side of the first cavity 212. The sealing component 300 is located in the second cavity 213. There is a gap 2121 between the inner wall of the first cavity 212 and the outer wall of the air intake rod 300. The gap 2121 gradually increases from left to right. By providing the gap 2121, the gap 2121 can reduce part of the pressure of the refrigerant, and then reduce the pressure of the refrigerant, thereby reducing the influence of the refrigerant on the sealing component 300, thereby ensuring the sealing effect of the sealing component 300.

[0027] In a further embodiment of the present invention, Figure 1 As shown, it also includes a second seal 400, which is arranged between the inner wall of the installation cavity 210 and the outer wall of the air intake rod 300. The second seal 400 is arranged on the right side of the protrusion 310. The second seal 400 is used to seal the space between the inner wall of the installation cavity 210 and the outer wall of the air intake rod 300. By providing the second seal 400, a third seal is formed between the inner wall of the installation cavity 210 and the outer wall of the air intake rod 300, thereby improving the sealing effect.

[0028] During operation, the high-pressure refrigerant first passes through the gap 2121 to reduce part of the refrigerant pressure, and then passes through the sealing component 300 to reduce part of the refrigerant pressure. Since the high-pressure refrigerant is depressurized twice, the second seal 400 is less affected by the refrigerant. The second seal 400 can better seal the space between the bearing seat 200 and the air intake rod 300 to ensure that the refrigerant will not leak.

[0029] In a further embodiment of the present invention, Figure 1 As shown, the bearing assembly also includes a first bearing 500 and a second bearing 600, spaced apart in the left-right direction. Both the first bearing 500 and the second bearing 600 are sleeved around the intake rod 300 and located within the mounting cavity 210. The presence of the first bearing 500 and the second bearing 600 aligns the axis of the bearing seat 200 with the axis of the intake rod 300. The concentricity of the bearing seat 200 ensures consistent and stable rotation of the bearing seat 200 relative to the intake rod 300. This ensures that the seal within the bearing seat 200 cavity is aligned with the outer diameter of the intake rod 300 in a highly precise, concentric axis, effectively sealing the assembly. This significantly improves the life of the entire sealing assembly.

[0030] In a further embodiment of the present invention, Figure 1As shown, the first bearing 500 is arranged on the left side of the sealing member 300, or the first bearing 500 is arranged between the pressure cover 310 located on the left side of the elastic member 320 and the first sealing member 330 located on the left side of the elastic member 320, and the second bearing 600 is located on the right side of the protrusion 310. The two bearings are arranged in this way to ensure that the rotation between the bearing seat 200 and the intake rod 300 can run at high speed and ensure the sealing effect;

[0031] The first arrangement of the first bearing 500 is: arranged on the left side of the sealing member 300;

[0032] The second arrangement of the first bearing 500 is: arranged between the pressure cover 310 located on the left side of the elastic member 320 and the first sealing member 330 located on the left side of the elastic member 320 .

[0033] In a further embodiment of the present invention, Figure 1 As shown, the inner wall of the mounting cavity 210 has a card groove, the second seal 400 is located between the protrusion 310 and the second bearing 600, and a retaining spring 700 connected to the card groove is installed on the right side of the second bearing 600, so that under the action of the spring, the first seal 330 on the right is clamped between the right pressure cover 310 and the protrusion 310, and the second seal 400 is clamped between the protrusion 310 and the second bearing 600 to ensure the sealing effect.

[0034] In some embodiments of the present invention, Figure 1 As shown, a third seal 800 is provided between the outer side of the bearing seat 200 and the evaporator roller body 100 to prevent the refrigerant from leaking from the gap between the bearing seat 200 and the evaporator roller body 100 .

[0035] In a further embodiment of the present invention, Figure 1 As shown, the evaporator roller body 100 has a mounting hole 110, and the bearing seat 200 is inserted into the mounting hole 110 and welded to the evaporator roller body 100, so that the evaporator roller body 100 and the bearing seat 200 can be processed separately, and it is convenient to install the sealing component 300 on the bearing seat 200.

[0036] In some embodiments of the present invention, Figure 1 As shown, the elastic member 320 is a spring.

[0037] In a further embodiment of the present invention, Figure 1 As shown, the first chamber 212 is conical, ensuring the pressure relief effect.
