DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0032] like Figure 1-Figure 15 As shown, the present invention provides an ice cream machine, including a chassis 1, wherein a system assembly is arranged inside the chassis 1, a heat dissipation assembly plate 58 is arranged on the system assembly, a heat dissipation device matched with the heat dissipation assembly plate 58 is arranged on the inner wall of the rear end of the chassis 1, and the heat dissipation device includes a rotatable main shaft 8, and a plurality of evenly distributed fan-shaped leaves 26 are arranged at the periphery of the main shaft 8. When the main shaft 8 rotates, the fan-shaped leaves 26 can form a structure in which the fan-shaped leaves 26 rotate in a circular shape and deflect to open the heat dissipation device, and when the main shaft 8 stops rotating, the fan-shaped leaves 26 can be turned to a horizontal state and stop rotating to close the heat dissipation device.

[0033] like Figure 1-Figure 7As shown, the chassis 1 is used to install and seal the entire device. The system assembly includes a refrigeration system, a stirring system, a mixture container and a control system. The refrigeration system is usually composed of a compressor, a condenser, an evaporator and a refrigerant. The compressor is responsible for compressing the refrigerant and transmitting it to the condenser. The condenser dissipates heat to the surrounding environment, and the evaporator absorbs heat to evaporate the refrigerant to achieve refrigeration. The stirring system is used to stir the ice cream mixture evenly to prevent the ice crystals from being too large, thereby ensuring the fine texture of the ice cream. The stirrer is usually driven by an electric motor and can stir while cooling. The mixture container is where the ice cream mixture is stored. It is usually an insulated container that can maintain temperature and prevent external heat from affecting the production of ice cream. The control system is the brain of the ice cream machine, including various electronic components and sensors, which can monitor parameters such as temperature, stirring speed, and time. , and automatically adjust to ensure that the ice cream making process meets the requirements. The system assembly belongs to the prior art and will not be described in detail; the heat dissipation device can dissipate heat inside the chassis 1 when working, and the heat dissipation device is in a closed state when idle, which can play a sealing role, thereby reducing the entry of dust, improving the sealing effect, extending the service life, and preventing product pollution; through the cooperation of the main shaft 8 and the fan-shaped leaves 26, when the main shaft 8 rotates, the fan-shaped leaves 26 can be driven to rotate in a circle, and the fan-shaped leaves 26 will deflect a certain angle, which is more conducive to exhaust and accelerates heat dissipation. At this time, the heat dissipation device is in an open state; when the main shaft 8 stops rotating, the corresponding fan-shaped leaves 26 will stop moving in a circle, and the fan-shaped leaves 26 will flip to a horizontal state. At this time, the heat dissipation device is in a closed state, that is, it can play a better sealing effect when the ice cream machine is idle, thereby reducing dust pollution.

[0034] The inner wall of the main shaft 8 is provided with a driving disk 22 that can move forward and backward, and the inner ends of the fan-shaped leaves 26 are respectively rotatably connected to the outer surface of the main shaft 8. The heat dissipation device also includes an outer ring 63, and the outer ends of the fan-shaped leaves 26 are respectively rotatably connected to the inner wall of the outer ring 63. Cranks 25 are respectively fixed on the inner end surfaces of the fan-shaped leaves 26. A plurality of evenly distributed second connecting rods 24 are provided at the rear end of the driving disk 22, and one end of the second connecting rod 24 is respectively hinged on the corresponding crank 25, and the other end of the second connecting rod 24 is respectively hinged on the rear end surface of the driving disk 22.

[0035] like Figure 6-Figure 9 As shown, the drive disk 22 can be slidably connected to the inner wall of the main shaft 8, and the drive disk 22 can move forward and backward on the inner wall of the main shaft 8; the outer ring 63 is rotatably connected to the inner wall of the rear end of the chassis 1, and the outer ring 63 can limit the outer end of the fan-shaped leaf 26; the installation and shape of the drive disk 22, the second connecting rod 24, the crank 25, and the fan-shaped leaf 26 are as shown Fig. 9 As shown, when the driving disk 22 moves forward or backward, it can drive one end of the second connecting rod 24 to move, and the other end of the second connecting rod 24 will drive the crank 25 and the fan-shaped blades 26 to deflect and rotate, that is, control the heat dissipation device to open or close.

[0036] A circular baffle 16 is also fixedly connected to the inner wall of the main shaft 8, a second spring 23 is fixedly connected to the middle of the rear end surface of the circular baffle 16, the rear end of the second spring 23 is fixedly connected to the driving disk 22, and the inner walls at the upper and lower ends of the circular baffle 16 are slidably connected with a movable long slider 17, and the inner walls at the rear end of the long slider 17 are respectively fixedly connected to the first sliding pin 18, and two guide plates 19 matching the first sliding pin 18 are respectively fixedly connected to the upper and lower sides of the front end surface of the driving disk 22.

[0037] like Figure 7 As shown, the circular baffle 16 can block and support the second spring 23. The second spring 23 has a backward driving force on the driving disk 22 under normal conditions, even if the driving disk 22 is in the rearmost state under normal conditions, that is, the fan-shaped leaves 26 can be in a horizontal state under normal conditions, so that the heat dissipation device is closed; the two long sliders 17 can move inward or outward synchronously, and the installation and shape of the guide plate 19 and the first sliding pin 18 are as shown in FIG. Figure 8 As shown, the guide plate 19 is provided with an inclined surface 20 and a straight surface 21. When the long slider 17 and the first sliding pin 18 move inward, the first sliding pin 18 is engaged with the inclined surface 20, so that the guide plate 19 and the driving disk 22 can be driven to move forward, even if the fan-shaped leaf 26 is deflected, when the first sliding pin 18 moves inward to contact with the straight surface 21, the guide plate 19 and the driving disk 22 no longer move forward, that is, the corresponding driving disk 22 can be moved forward and backward in the specified space, that is, the corresponding fan-shaped leaf 26 is deflected and swung within the specified angle range, that is, the fan-shaped leaf 26 is deflected within the range of 0-45 degrees; when the long slider 17 and the first sliding pin 18 move inward to contact with the straight surface 21, the guide plate 19 and the driving disk 22 no longer move forward, that is, the corresponding driving disk 22 can be moved forward and backward in the specified space, that is, the corresponding fan-shaped leaf 26 is deflected and swung within the specified angle range, that is, the fan-shaped leaf 26 is deflected within the range of 0-45 degrees; When the block 17 and the first sliding pin 18 move outward to reset, the corresponding guide plate 19 and the driving disk 22 will move backward to reset under the elastic force of the second spring 23, that is, the corresponding fan-shaped leaf 26 can be flipped to a horizontal state and reset; under the elastic force of the second spring 23 itself, when the first sliding pin 18 moves inward or outward, the inclined surface 20 of the guide plate 19 can always be in contact and engage with the first sliding pin 18; through the cooperation of the guide plate 19 and the first sliding pin 18, when the driving disk 22 and the guide plate 19 move forward alone, they will be out of contact with the first sliding pin 18 and will not cause motion interference with the first sliding pin 18.

[0038] The inner walls at the left and right ends of the main shaft 8 are respectively slidably connected with second guide rods 10, the outer ends of the two second guide rods 10 are respectively fixed with centrifugal balls 11, the inner ends of the two second guide rods 10 are respectively fixed with connecting seats 14, and the connecting seats 14 are respectively hinged with two first connecting rods 15 opened outward, and the other ends of the first connecting rods 15 are respectively hinged on the corresponding long sliders 17, and the outer surfaces of the second guide rods 10 are also respectively covered with first springs 13 that cooperate with the connecting seats 14.

[0039] like Figure 7As shown, the second guide rod 10 can slide around the inner wall of the main shaft 8. Through the centrifugal balls 11, when the main shaft 8 rotates, the two centrifugal balls 11 can rotate in a circle and move outward under the action of centrifugal force; the installation and shape of the connecting seat 14, the first connecting rod 15, the second guide rod 10, and the first spring 13 are as shown Figure 7 As shown, the outer ends of the first springs 13 are respectively fixed to the inner wall of the main shaft 8, and the other ends of the first springs 13 are respectively fixed to the corresponding connecting seats 14. The first springs 13 always have an inward driving force on the connecting seats 14. Even if the connecting seats 14 are at the innermost end under normal conditions, when the connecting seats 14 and the first connecting rods 15 move outward, they can drive the corresponding long sliders 17 to move inward. When the connecting seats 14 and the first connecting rods 15 move inward, they can drive the corresponding long sliders 17 to move outward. When the main shaft 8 rotates, It can drive the two centrifugal balls 11 to move outward, and can also drive the corresponding connecting seat 14 to move outward and the long slider 17 to move inward. When the long slider 17 moves inward, it will drive the first sliding pin 18 to move inward, so that the driving disk 22 moves forward, and the corresponding fan-shaped leaves 26 are deflected and opened. When the main shaft 8 stops rotating, the corresponding centrifugal balls 11 and the driving disk 22 will be reset to the initial state under the elastic force of the first spring 13 and the second spring 23, that is, the corresponding fan-shaped leaves 26 are flipped and reset to the horizontal state; Figure 4 or Figure 5 As shown, a motor bracket 5 is fixedly connected to the rear inner wall of the chassis 1, a first motor 4 is fixedly connected to the inner wall of the motor bracket 5, and a main shaft 8 is fixedly connected to the output end of the first motor 4. The function of the motor is to provide rotational force for the main shaft 8. The motor is existing technology and will not be described in detail.

[0040] A rectangular rod 27 is slidably connected to the inner wall of the rear end of the main shaft 8, and the rectangular rod 27 is fixedly connected to the rear end surface of the driving disk 22. A rotatable handle 28 is provided at the rear end of the rectangular rod 27, and two first discs 29 are coaxially fixedly connected to the front end of the handle 28. Wedge blocks 33 are slidably connected to the inner walls of the left and right ends of the rectangular rod 27, and third guide rods 35 are fixedly connected to the inner ends of the two wedge blocks 33, and second sliding pins 31 are fixedly connected to the inner ends of the third guide rods 35, and inclined grooves 30 matching the second sliding pins 31 are respectively provided on the first discs 29.

[0041] like Figure 8-Figure 10 As shown, the handle 28 and the inner wall of the first disc 29 are fixedly connected with a rotating shaft, which is rotatably connected to the inner wall of the rectangular rod 27, limiting the first disc 29 and the handle 28 to be able to rotate; the wedge block 33, the first disc 29, and the third guide rod 35 are installed and shaped as shown in FIG. Fig.10As shown, the wedge block 33 can slide left and right on the inner wall of the rectangular rod 27, and the third spring 34 is respectively sleeved on the outer surface of the third guide rod 35. The inner walls of the left and right ends of the rectangular rod 27 are respectively fixed with square baffles 32, and the third guide rod 35 is respectively slidably connected to the inner wall of the square baffle 32. One end of the third spring 34 is fixed to the square baffle 32, and the other end of the third spring 34 is fixed to the wedge block 33. The function of the third spring 34 is to drive the wedge block 33 to have a driving force outward, so that the wedge block 33 is in the outermost end state under normal conditions. When the handle 28 is turned, the first disc 29 can be driven to rotate. When the first disc 29 rotates, the third guide rod 35 and the wedge-shaped block 33 are driven to move inward or outward synchronously through the engagement of the inclined groove 30 and the second sliding pin 31. When a large amount of dust adheres to the fan-shaped leaves 26 and needs to be cleaned, since the heat dissipation device is in a closed state under normal conditions, the corresponding driving disc 22 can be driven to move forward by driving the handle 28 and the rectangular rod 27 forward, and the driving disc 22 will compress the second elastic member when it moves forward. The wedge-shaped block 33 is provided with a spring 23. When the rectangular rod 27 is driven to make the wedge-shaped block 33 contact the main shaft 8, it can move inward under the action of the inclined end surface of the wedge-shaped block 33. When the wedge-shaped block 33 moves inward to break away from the inner wall of the rear end of the main shaft 8, the wedge-shaped block 33 will move outward to reset under the elastic force of the third spring 34. Since the rear end surface of the wedge-shaped block 33 is arranged parallel to the inner wall of the rear end of the main shaft 8, the wedge-shaped block 33 will prevent the rectangular rod 27 from resetting backward. At this time, the corresponding driving disk 22 can drive the fan-shaped leaf 2 6 is flipped 90 degrees to make the fan-shaped leaves 26 in a vertical state, which is convenient for cleaning the dust on the surface of the fan-shaped leaves 26. When the fan-shaped leaves 26 need to be reset, the driving handle 28 is rotated to move the two wedge-shaped blocks 33 inwardly into the inner wall of the rectangular rod 27. At this time, the wedge-shaped blocks 33 are no longer in contact with the inner wall of the main shaft 8, and the corresponding driving disk 22 and the rectangular rod 27 will move backwards and reset to the initial state under the elastic force of the second spring 23. No more details will be given, that is, the corresponding fan-shaped leaves 26 are flipped and reset to the horizontal state.

[0043] like Figure 1-Figure 3As shown in Figures 1 and 11, the storage box 39 can store ice cream raw materials, and a variety of ice cream raw materials can be stored through the storage slots. A cover plate 2 is placed on the upper end of the storage box 39, and the cover plate 2 can seal the storage slots. A bracket 38 is also fixedly connected to the inner wall of the upper end of the chassis 1, and the bracket 38 plays a supporting role for the storage box 39. Through the provided measuring device, the raw materials in the storage box 39 can be measured in real time, which is convenient for timely filling the storage box 39 with ice cream raw materials. When the main shaft 8 is working, the measuring device can be opened to perform real-time measurement and monitoring of the inside of the storage box 39.

The fourth spring 46 always has an upward driving force on the anti-drop pad 47, so that the arrow 48 and the short guide rod 45 are in the topmost state under normal conditions. By setting the scale plate 49 and the arrow 48 in cooperation, the descent amount of the arrow 48 can be observed in real time; the long guide rod 42 can move back and forth on the inner wall of the sleeve 43, and the small slider 41 can move up and down on the T-shaped seat 40, that is, when the extension frame 6 moves forward or backward, it can drive the small slider 41, the long guide rod 42, and the first tooth plate 44 to move forward or backward, and when the first tooth plate 44 and the long guide rod 42 move downward or upward, it can drive the sleeve 43, the short guide rod 45, the small slider 41, the arrow 48, etc. to move upward or downward, and the two do not affect each other.

[0049] like Fig.12 or Fig.13As shown, the buoyancy ball 51 can detect the height of the water level in the storage tank, the T-shaped rod 52 can be slidably connected to the inner wall of the storage box 39, and the U-shaped plate 55 can be slidably connected to the rear end surface of the storage box 39. When the buoyancy ball 51 moves up and down, it can drive the long connecting rod 50 to swing up and down. When the long connecting rod 50 swings up and down, the corresponding T-shaped rod 52 can be driven to move forward and backward through the engagement of the first live pin 53 and the short key groove 54. When the T-shaped rod 52 moves forward and backward, it can drive the second live pin 56 to move forward and backward.

When the main shaft 8 rotates the extension frame 6 to move forward, the L-shaped baffle rod 36 can be driven to move forward. When the L-shaped baffle rod 36 moves forward to the upper end position of the baffle seat 37, it can block the baffle seat 37 from moving upward, thereby preventing the storage box 39 from accidentally detaching.

The wire grooves 60 are provided to facilitate the installation of the wires 62, so that the thermoelectric chip is electrically connected to the battery, that is, the thermoelectric chip can store electrical energy when generating electricity. By loading the thermoelectric chip onto the heat dissipation assembly plate 58, the heat generated by the equipment can be converted into electrical energy for storage and reuse, thereby saving energy and reducing emissions.

[0052] When the present invention is in use, the heat dissipation device can dissipate heat inside the chassis 1 when working, and is in a closed state when idle, which can play a sealing role, thereby reducing the entry of dust, improving the sealing effect, extending the service life, and preventing product contamination; through the cooperation of the set main shaft 8 and fan-shaped leaves 26, when the main shaft 8 rotates, the fan-shaped leaves 26 can be driven to rotate in a circle, and the fan-shaped leaves 26 will deflect a certain angle, which is more conducive to exhaust and accelerates heat dissipation. At this time, the heat dissipation device is in an open state; when the main shaft 8 stops rotating, the corresponding fan-shaped leaves 26 will stop moving in a circle, and the fan-shaped leaves 26 will flip to a horizontal state. At this time, the heat dissipation device is in a closed state, that is, it can play a better sealing effect when the ice cream machine is idle, thereby reducing dust pollution.
