[0022] Example 1
[0023] See also Figure 1-5 The utility model provides an embodiment: a fresh tobacco leaf tissue grinding device, including a grinding bin 1 and a pad 16. The top of the grinding bin 1 is open and equipped with a cover. The tops of multiple pads 16 are fixedly connected to a support frame 18. Multiple pads 16 are symmetrical about the vertical center line of the support frame 18. The device can be placed on an external horizontal plane through the pads 16 to prevent wear between the bottom of the support frame 18 and the external water surface. A cover 11 is threadedly connected to the open top of the grinding bin 1. A handle 12 is fixedly connected to the top of the cover 11. The outer size of the cover 11 matches the outer size of the grinding bin 1. By rotating the cover 11 with the handle 12, the grinding bin 1 can be opened and the fresh tobacco leaves to be ground can be placed in the grinding bin 1, and the cover 11 can be closed.
[0024] In this embodiment, an annular ice groove 2 is provided on the outside of the grinding bin 1, and a ring cover 10 is movably connected to the top of the annular ice groove 2, and a plurality of vertical pipes 3 are evenly distributed in a ring shape about the central axis of the annular ice groove 2, and the inner side of the annular ice groove 2 is in contact with the outer side of the grinding bin 1, and the bottom of the annular ice groove 2 is connected with a plurality of vertical pipes 3, and one side of the vertical pipes 3 is in contact with the outer side of the grinding bin 1, and the bottom ends of the plurality of vertical pipes 3 are connected with the same annular cooling box 4, and the top surface of the annular cooling box 4 is in contact with the bottom surface of the grinding bin 1, and one side of the annular cooling box 4 is connected with a drain pipe 9, and the ring cover 10 is removed. When the ice cubes melt, they absorb heat, so that the top of the grinding bin 1 can be cooled by absorbing heat. When the ice cubes melt into ice water, they flow into the annular cooling box 4 through the vertical pipe 3. When the ice water flows through the vertical pipe 3, it can absorb heat from the side wall of the grinding bin 1, so as to reduce the internal temperature of the grinding bin 1, prevent the internal temperature of the grinding bin 1 from being too high, which may cause the chemical components inside the fresh tobacco leaves to denature at high temperature, and ensure the quality of tobacco leaf grinding. When the ice water flows into the annular cooling box 4, it can cool the bottom of the grinding bin 1. The bottom end of the annular cooling box 4 is fixedly connected with a plurality of connecting columns 5, and the bottom ends of the plurality of connecting columns 5 are fixedly connected with the same motor 6. The output shaft end of the motor 6 is fixedly connected with a connecting shaft 7. The output shaft of the motor 6 passes through the bottom of the annular cooling box 4 and the grinding chamber 1, and the inner ring of the annular cooling box 4 fits with the outer side of the output shaft of the motor 6. The outer side of the connecting shaft 7 is fixedly connected with a plurality of blades 8. The central axis of the connecting shaft 7 coincides with the vertical center line of the grinding chamber 1. The plurality of blades 8 are evenly distributed in a ring shape about the central axis of the connecting shaft 7. One side of the support frame 18 A control box 17 for controlling the rotation of the motor 6 is fixedly connected, and the control box 17 and the motor 6 are electrically connected. Starting the motor 6 causes the connecting shaft 7 to rotate, which can drive the blade 8 to rotate, thereby facilitating the grinding of the fresh tobacco leaves in the grinding bin 1. The start and speed of the motor 6 can be controlled by the control box 17. The annular cooling box 4 filled with ice water, in conjunction with the use of the connecting column 5, can isolate the heat from the motor 6 when it is working from being transmitted into the grinding bin 1, thereby further improving the heat dissipation performance of the device. The water in the annular cooling box 4 can be discharged by using the drain pipe 9.
[0025] In this embodiment, a support frame 18 is provided at the bottom of the motor 6, and round shafts 13 are threadedly connected on both sides of the motor 6, and the two round shafts 13 are coaxially arranged, and the round shafts 13 and the support frame 18 are rotatably connected. A knob 14 is fixedly connected to the end of the round shaft 13 on one side of the motor 6, and a locking nut 15 is threadedly connected to the end of the round shaft 13 on the other side of the motor 6. By loosening the locking nut 15 and rotating the knob 14, and using the round shaft 13, the motor 6 can be slightly rotated up and down, thereby driving the grinding bin 1 to rotate, which is convenient for shaking the tobacco leaves in the grinding bin 1, which is beneficial to the uniform grinding of the tobacco leaves. At the same time, after the grinding is completed, it is also convenient to pour the tobacco leaves out of the grinding bin 1.
[0026] Working principle: When using the device, firstly, the device can be placed on the external horizontal plane through the feet 16 to prevent the bottom of the support frame 18 from being worn between the external water surface, and the top opening of the grinding bin 1 can be opened by turning the cover 11 through the handle 12, and the fresh tobacco leaves to be ground are placed in the grinding bin 1, and the cover 11 is closed, and the motor 6 is started to rotate the connecting shaft 7, which can drive the blade 8 to rotate, so as to grind the fresh tobacco leaves in the grinding bin 1, and the start and speed of the motor 6 can be controlled by the control box 17, and the locking nut 15 is loosened, and the knob 14 is rotated, and the use of the round shaft 13 can make the motor 6 rotate slightly up and down, so as to drive the grinding bin 1 to rotate, so as to shake the tobacco leaves in the grinding bin 1, which is conducive to the uniform grinding of the tobacco leaves, and at the same time, after the grinding is completed, it is also convenient to pour the tobacco leaves out of the grinding bin 1. When the tobacco leaves are ground, the ring cover 10 is removed and the annular ice trough 2 can be opened. Ice cubes can be placed in the annular ice trough 2. The ice cubes in the annular ice trough 2 absorb heat when they melt, so that the top of the grinding bin 1 can be cooled by absorbing heat. When the ice cubes melt into ice water, they flow into the annular cooling box 4 through the vertical pipe 3. When the ice water flows through the vertical pipe 3, it can absorb heat from the side wall of the grinding bin 1, thereby reducing the internal temperature of the grinding bin 1, preventing the temperature in the grinding bin 1 from being too high, causing the internal chemical components of the fresh tobacco leaves to denature at high temperature, and ensuring the quality of tobacco leaf grinding. When the ice water flows into the annular cooling box 4, it can cool and dissipate heat from the bottom of the grinding bin 1. At the same time, the annular cooling box 4 equipped with ice water, in conjunction with the use of the connecting column 5, can isolate the heat from the motor 6 when it is working and transfer it into the grinding bin 1, further improving the heat dissipation performance of the device. The water in the annular cooling box 4 can be discharged by the drain pipe 9.
[0027] Example 2
[0028] The difference between this embodiment and embodiment 1 is that a water inlet hole is further provided on the annular ice trough, and a water outlet hole is provided on the annular cooling box. The water inlet hole and the water outlet hole are respectively connected to an external ice water tank through a hose provided with a micro pump. In this way, the low-temperature water in the ice water tank can be pumped into the annular ice trough by the micro pump and then refluxed into the ice water tank through the vertical pipe and the annular cooling box in sequence.

It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
