[0032] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0033] A snow melting machine for preventing snow accumulation, as shown in Figures 1 to 5, includes a body 1, a rear seat 2, and a material tank 3. The rear seat 2 and the material tank 3 are respectively disposed on the upper part of the body 1, with the rear seat 2 located at the rear of the body 1 and the material tank 3 located at the front of the body 1. The rear part of the material tank 3 is sealed to the rear seat 2. A drive mechanism is disposed inside the rear seat 2, and a discharge chamber 31 is disposed inside the material tank 3. The discharge chamber 31 is provided with an evaporator 61 and a spiral scraper 7 rotatably mounted around the evaporator 61. The spiral scraper 7 is connected to the drive mechanism. The upper part of the discharge chamber 31 is provided with a front guide arc surface 32 and two rear guide arc surfaces 33. The front part of the front guide arc surface 32 is connected to the front side wall of the discharge chamber 31, the rear part of the front guide arc surface 32 is connected to the front part of the two rear guide arc surfaces 33, the upper part of the two rear guide arc surfaces 33 is connected to the upper wall of the discharge chamber 31, and the lower part of the two rear guide arc surfaces 33 is connected to the left and right side walls of the discharge chamber 31. In traditional slush machines, slush tends to accumulate at the front and top of the material container 3, preventing the spiral scraper 7 from completely extruding it and causing residue. This invention addresses this by using two rear guide arc surfaces 33 to guide the slush downwards from the top of the discharge chamber 31, preventing it from accumulating above the spiral scraper 7. A front guide arc surface 32 guides the slush downwards from the front of the discharge chamber 31, preventing it from accumulating in front of the spiral scraper 7. The front guide arc surface 32 and the two rear guide arc surfaces 33 form a continuous curved flow channel, covering the upper and front areas of the discharge chamber 31, guiding the slush to slide naturally along the arc surface. This prevents slush from accumulating at the top or front wall corner of the discharge chamber 31 when the spiral scraper 7 rotates, reducing residue. When changing flavors, there is no need to manually scrape off the residue, preventing flavor mixing.

[0034] Specifically, the upper parts of the two rear guide arc surfaces 33 are connected and tangent to each other, and the lower parts of the two rear guide arc surfaces 33 are tangent to the left and right side walls of the discharge cavity 31, respectively. The upper wall of the discharge cavity 31 is formed by the two rear guide arc surfaces 33, forming a semi-circular cross-section of the upper wall of the discharge cavity 31. The tangency of the arc surfaces ensures that the flow path of the ice slush has no abrupt changes or sharp angles, reducing frictional resistance and ensuring that the ice slush smoothly transitions to the lower part of the discharge cavity 31. The tangential connection between the rear guide arc surfaces 33 and the side walls prevents ice slush from remaining at the junction of the left and right side walls and the cavity.

[0035] Specifically, chamfers 34 with smooth transitions are provided between the front guide arc surface 32 and the two rear guide arc surfaces 33, and between the front guide arc surface 32 and the front sidewall of the discharge chamber 31. The chamfers 34 further eliminate the small sharp edges at the connection of each arc surface, prevent ice sand particles from getting stuck at the joints, ensure that the ice sand flows without resistance after being peeled off from the spiral scraper 7, and improve the smoothness of discharge.

[0036] Specifically, a connecting portion 321 extends downward from the left and right sides of the front part of the guide arc surface 32. The front parts of the two connecting portions 321 are connected to the front sidewall of the discharge cavity 31, and the rear parts of the two connecting portions 321 are connected to the left and right sidewalls of the discharge cavity 31, respectively. The connecting portions 321 extend to form a flow guiding structure, which further guides the ice sand diverted by the guide arc surface 32 to the left and right sides of the discharge cavity 31, avoiding the accumulation of ice sand at the front end; it also enhances the structural continuity between the guide arc surface 32 and the cavity wall, preventing ice sand from seeping into the gap between the guide surface and the cavity wall.

[0037] Specifically, the inner diameter of the front end of the discharge chamber 31 is smaller than the inner diameter of the rear end of the discharge chamber 31. By utilizing the tapered structure, the extrusion pressure is increased as the slush moves forward, accelerating the speed at which the slush is extruded forward. The reduced inner diameter at the front end decreases the diffusion space of the slush at the front end, thus reducing the probability of accumulation.

[0038] Specifically, a converging arc surface 35 is provided at the lower part of the discharge chamber 31. The left and right sides of the converging arc surface 35 are connected to and tangent to the left and right side walls of the discharge chamber 31, respectively. The converging arc surface 35 gathers the dispersed ice sand towards the center, forming a concentrated flow path and increasing the discharge density. The tangent design between the arc surface and the chamber wall prevents the ice sand from being stuck at the bottom of the side wall during the gathering process.

[0039] Specifically, a discharge port 36 is provided at the lower part of the front end face of the material barrel 3, and an upward-opening feeding box 37 is provided at the upper part of the material barrel 3. The feeding box 37 is located at the rear of the material barrel 3, and a strip-shaped feeding port 371 is opened at the bottom of the feeding box 37. A central filter bar 361 and two side filter bars 362 are vertically arranged at the discharge port 36. The two side filter bars 362 are symmetrically arranged on both sides of the central filter bar 361. The rear of the central filter bar 361 is provided with two backward-inclined cutting surfaces to form a triangular cross-sectional shape. The central filter bar 361 forms a blade through the inclined cutting surfaces, which performs secondary crushing when the ice slush passes through the discharge port 36, improving the fineness of the ice slush. The side filter bars 362 and the central filter bar 361 cooperate to form a uniform screening structure, avoiding blockage of the discharge port 36 and ensuring uniform extrusion of the ice slush.

[0040] Specifically, the feed inlet 371 is located at the rear of the bottom surface of the discharge box 37, and the feed inlet 371 extends horizontally through the bottom surface of the discharge box 37. The bottom surface of the discharge box 37 is inclined downwards from front to back. A cover plate 372 is pivotally connected to the upper part of the discharge box 37, and the cover plate 372 is snap-fitted to the discharge box 37. The inclined bottom surface of the discharge box 37 guides the raw material to flow automatically to the feed inlet 371, avoiding the accumulation of raw material at the front of the discharge box 37. The snap-fit ​​design of the cover plate 372 facilitates quick opening and closing, prevents external contamination, and ensures convenient feeding.

[0041] Specifically, a discharge assembly 4 is provided on the front end face of the material barrel 3. The discharge assembly 4 includes a discharge cylinder, a discharge handle 42, a connecting rod 43, a return spring 44, and a sealing plug 45. The discharge cylinder is provided with an outer cylinder 411 and two connecting side plates 412. The two connecting side plates 412 are spaced apart on the front end face of the material barrel 3 and located on the left and right sides of the discharge port 36. The outer cylinder 411 is snapped into the front part of the two connecting side plates 412. The sealing plug 45 and the discharge handle 42 are rotatably installed between the two connecting side plates 412. The discharge handle 42 is located above the sealing plug 45. The sealing plug 45 is sealed to the discharge port 36. The upper end of the connecting rod 43 is hinged to the discharge handle 42, and the lower end of the connecting rod 43 is hinged to the sealing plug 45. A hinge and a return spring 44 are provided between the sealing plug 45 and the material barrel 3; the upper part of the machine body 1 is provided with an arc-shaped mounting groove 11, and at least one connecting slide groove 12 with a front opening is provided on the left and right sides of the arc-shaped mounting groove 11; at least one connecting protrusion 38 is provided on the left and right sides of the outer wall of the material barrel 3, and each connecting protrusion 38 is inserted into the corresponding connecting slide groove 12; a snap-fit ​​knob 8 is rotatably installed on the left and right sides of the rear seat 2, and a snap-fit ​​slide groove 81 is provided on the inner side of the snap-fit ​​knob 8; a snap-fit ​​post 39 is provided on the left and right sides of the corresponding outer wall of the material barrel 3, and the two snap-fit ​​posts 39 are snap-fitted to the corresponding snap-fit ​​slide groove 81; a sealing ring 22 is provided between the material barrel 3 and the rear seat 2. During the discharge operation, by rotating and pressing the discharge handle 42 backward, the discharge handle 42 rotates, driving the connecting rod 43, which in turn drives the sealing plug 45 to rotate, moving the sealing plug 45 away from the discharge port 36, thus discharging the material. After discharging, releasing the discharge handle 42 causes the sealing plug 45 to return to its original position under the action of the return spring 44, thereby sealing the discharge port 36 and achieving precise opening and closing control. The outer cylinder 411 is disassembled to expose the sealing plug 45, facilitating cleaning of the sealing plug 45 and the discharge port 36, avoiding cleaning dead spots, and preventing bacterial growth. The material bucket 3 is positioned and limited by the connecting slide 12, and then locked and fixed by the snap-fit ​​knob 8, enabling quick assembly and disassembly. The sealing ring 22 ensures a tight seal between the material bucket 3 and the rear seat 2, facilitating thorough cleaning and convenient use.

[0042] Specifically, the interior of the body 1 is equipped with a condenser 62 and a compressor 63. The evaporator 61 is connected to the compressor 63, the compressor 63 is connected to the condenser 62, and the condenser 62 is connected to the evaporator 61. A control panel 13 is provided on the front side of the body 1. The drive mechanism includes a drive motor 51, a reducer 52, and a transmission shaft 53. The drive motor 51 is connected to the reducer 52, and the reducer 52 is connected to the transmission shaft 53. The rear end of the evaporator 61 is fixedly installed on the front end face of the rear seat 2. The front end of the transmission shaft 53 passes through the evaporator 61 and is fixedly connected to the front end of the spiral scraper 7. A control circuit 21 is provided inside the rear seat 2. The control panel 13, the compressor 63, and the drive motor 51 are electrically connected to the control circuit 21. The drive motor 51 is reduced in speed by the reducer 52 and then drives the spiral scraper 7 through the transmission shaft 53. The structure is simple and the cost is low. The speed of the drive motor 51 and the cooling power of the compressor 63 are adjusted by the control panel 13 to adapt to different beverage viscosities and avoid the spiral scraper 7 from getting stuck due to being too hard or piling up due to being too soft.
