Fig.13As shown in the figure, an ice cream scoop body 9 is arranged inside the placing cylinder 8, a matching lifting mechanism is connected between the placing cylinder 8 and the water storage cylinder 7, and a closed water inlet mechanism and an open cover drainage mechanism are connected to the water storage cylinder 7; when working, the prior art usually uses an insulating inner cavity to store the ice cream when keeping it warm, and when the ice cream is transported and sold, the heat preservation device needs to be opened and closed repeatedly, which increases the heating speed of the ice cream and affects the eating taste of the ice cream, and in the process of selling the ice cream, a spoon needs to be used to scoop out the ice cream and put it in the serving, and the spoon is difficult to collect effectively during use, and the spoon will produce sticky residues of ice cream during repeated use, thereby The above problems are affected, and the purchaser's desire to buy is reduced. The technical solution can solve the above problems, and the specific working method is as follows: the ice cream is placed inside the filling tube 4, and the top of the heat preservation box 1 is sealed with the sealing cover 5, and the internal and external temperature exchange is reduced by the heat insulation tube 2, so as to extend the heat preservation time of the ice cream, and through the contact between the multiple phase change cold storage plates 3 and the filling tube 4, when the sealing cover 5 is opened and the temperature of the filling tube 4 is increased, the phase change cold storage plates 3 release the stored cold to the filling tube 4 by contact conduction, so that the ice cream always maintains a stable storage temperature, thereby ensuring the taste of the ice cream, and in the filling tube 4, the sealing cover 5 is opened and the temperature of the filling tube 4 is increased. When the ice cream inside the filling cylinder 4 is to be sold and placed, the sealing cover 5 is opened, and the placing cylinder 8 automatically rises from the inside of the water storage cylinder 7 under the action of the lifting mechanism, thereby driving the ice cream scoop body 9 to rise from the inside of the water storage cylinder 7, making it convenient to take out and use the ice cream scoop body 9, and when the sealing cover 5 is opened, the clean water inside the water storage cylinder 7 is discharged through the action of the cover opening and drainage mechanism. After the ice cream inside the filling cylinder 4 is placed, the ice cream scoop body 9 is placed inside the placing cylinder 8 again, and the sealing cover 5 is closed. When the sealing cover 5 is closed, the placing cylinder 8 moves downward and returns to the initial position through the action of the lifting mechanism, so that the ice cream scoop body 9 is completely moved. The ice cream scoop 9 is then rinsed with water and then rinsed with the clean water. The scoop 9 is then rinsed with the clean water. The scoop 9 is rinsed with the clean water. The scoop 9 is then rinsed with the clean water. The scoop 9 is then rinsed with the clean water.

The top of the pressure rod 14 contacts and squeezes, and the L-shaped squeezing rod 14 drives the limiting ring 10 to move downward after being squeezed. The limiting ring 10 moves vertically downward along the sliding connection of the light rod 11 and squeezes the first spring 13 to produce compression deformation, thereby causing the placement tube 8 to move downward inside the water storage tube 7, and drives the ice cream scoop body 9 to move completely into the water storage tube 7 for placement. When the sealing cover 5 is opened along the hinge, the L-shaped squeezing rod 14 loses the squeezing effect of the sealing cover 5, and under the elastic stretching action of multiple first springs 13, the limiting ring 10 drives the placement tube 8 to move upward, thereby causing the ice cream scoop body 9 to rise, and the gripping end of the ice cream scoop body 9 moves to the top of the water storage tube 7, which is convenient for taking and using the ice cream scoop body 9.

[0026] As a further embodiment of the present invention, the closed water inlet mechanism comprises a water storage housing 15 (such as Fig.10 As shown in the figure, the water storage shell 15 is fixedly connected to the side of the insulation cylinder 2, and a first U-shaped tube 16 is fixedly connected between the bottom of the water storage shell 15 and the bottom of the water storage cylinder 7. A one-way valve 1601 is fixedly installed at one end of the first U-shaped tube 16 close to the water storage cylinder 7. A plug-in rod 17 is fixedly connected to the L-shaped extrusion rod 14, and the plug-in rod 17 is slidably inserted on the first U-shaped tube 16.

When the sealing cover 5 is opened along the hinge, the L-shaped extrusion rod 14 moves upward and drives the plug rod 17 to move upward synchronously. The connecting hole 18 on the plug rod 17 moves to the top of the first U-shaped tube 16, thereby releasing the internal connection of the first U-shaped tube 16, so that water cannot be replenished into the water storage cylinder 7 after the sealing cover 5 is opened, so that the drainage and water intake of the water storage cylinder 7 can be carried out separately, and the top of the sliding connection between the first U-shaped tube 16 and the plug rod 17 is blocked by the sealing ring 19 to prevent the connecting hole 18 from being synchronously connected with the inner and outer sides of the first U-shaped tube 16 during the movement, thereby ensuring the sealing during the connection process, and the one-way valve 1601 on the first U-shaped tube 16 prevents the clean water inside the water storage cylinder 7 from flowing back, thereby preventing the clean water inside the water storage shell 15 from being polluted.

[0027] As a further embodiment of the present invention, the cover opening drainage mechanism includes a drainage pipe 21, which is fixedly connected to the axis of the bottom of the water storage cylinder 7, one end of the drainage pipe 21 passes through the insulation box 1 and extends to the outside of the insulation box 1, and a sealing piston 22 (such as Fig.13 As shown in the figure, one end of the sealing piston 22 is slidably sealed at the fixed connection between the water storage cylinder 7 and the drain pipe 21; during operation, when the sealing cover 5 is closed on the top of the heat preservation box body 1 along the hinge, the placement cylinder 8 is located at the bottom surface inside the water storage cylinder 7, and one end of the sealing piston 22 is slidably sealed at the fixed connection between the water storage cylinder 7 and the drain pipe 21. When the sealing cover 5 is opened along the hinge, the placement cylinder 8 moves upward along the inside of the water storage cylinder 7, thereby driving one end of the sealing piston 22 to disengage from the fixed connection between the water storage cylinder 7 and the drain pipe 21, so that the clean water inside the water storage cylinder 7 is discharged along the drain pipe 21, and the clean water in the placement cylinder 8 flows into the inside of the water storage cylinder 7 along the water inlet groove 20, and is discharged along the drain pipe 21, thereby emptying the clean water inside the water storage cylinder 7 after use.

[0028] As a further embodiment of the present invention, a second U-shaped tube 23 (such as Figure 7 As shown in the figure, one end of the second U-shaped tube 23 is fixedly connected to the bottom of the water storage shell 15, and the other end of the second U-shaped tube 23 is located outside the water storage shell 15 and is fixedly connected to a funnel 24, and the second U-shaped tube 23 is made of transparent plastic. When working, clean water is poured into the second U-shaped tube 23 through the funnel 24, and through the fixed connection between the second U-shaped tube 23 and the bottom of the water storage shell 15 and the transparent material of the second U-shaped tube 23, as the liquid level inside the water storage shell 15 decreases, the liquid level of the second U-shaped tube 23 decreases synchronously. According to the liquid level of the second U-shaped tube 23, the amount of water stored in the water storage shell 15 can be intuitively seen, so that the clean water is added to the water storage shell 15 in time.

The shielding cover 25 is opened along the hinge to replenish the clean water into the funnel 24.

[0030] As a further implementation scheme of the present invention, the insulation tube 2 has an inner and outer double-layer structure, and there is a vacuum state between the inner and outer double layers of the insulation tube 2; when working, the heat is isolated by the vacuum insulation layer of the insulation tube 2, which effectively reduces the heat conduction caused by contact conduction and increases the insulation time of the ice cream.

[0031] As a further embodiment of the present invention, the snap-fit ​​positioning mechanism includes two movable grooves 26 (such as Figure 2 As shown, two movable grooves 26 are provided on one side of the sealing cover 5, the hinged positions of the movable groove 26 and the sealing cover 5 are arranged opposite to each other, a connecting frame 27 is arranged inside the movable groove 26, one end of the connecting frame 27 is fixedly connected with a buckle 28, and two connecting pins 29 are slidably inserted on the connecting frame 27 (as shown in FIG. Fig. 9As shown in the figure, the connecting pins 29 are all fixedly connected to the corresponding movable grooves 26, and the connecting pins 29 are all sleeved with second springs 30, which are fixedly connected between the corresponding connecting frame 27 and the connecting pins 29.

[0032] As a further implementation scheme of the present invention, the two buckles 28 are of an arc-wrapped edge structure, and a pull rod 32 is fixedly connected between the two buckles 28; when working, the two buckles 28 are driven to move synchronously by pulling the pull rod 32, thereby synchronously releasing the clamping and positioning between the two buckles 28 and the corresponding limit blocks 31.

[0033] Working principle of the present invention: The ice cream is placed inside the filling cylinder 4, and the top of the heat preservation box 1 is sealed with a sealing cover 5, and the temperature exchange between the inside and the outside is reduced by the heat insulation cylinder 2, so as to prolong the heat preservation time of the ice cream, and through the contact between the multiple phase change cold storage plates 3 and the filling cylinder 4, when the sealing cover 5 is opened and the temperature of the filling cylinder 4 is increased, the phase change cold storage plates 3 release the stored cold to the filling cylinder 4 by contact conduction, so that the ice cream always maintains a stable storage temperature, so as to ensure the taste of the ice cream, and when the ice cream inside the filling cylinder 4 is sold and served, by opening the sealing cover 5, the placing cylinder 8 automatically rises from the inside of the water storage cylinder 7 under the action of the lifting mechanism, thereby driving the ice cream scoop body 9 to rise from the inside of the water storage cylinder 7, so as to facilitate the taking and use of the ice cream scoop body 9, and when the sealing cover 5 is opened, the clean water inside the water storage cylinder 7 is discharged by the action of the cover opening drainage mechanism, and the ice cream scoop body 9 is discharged when the sealing cover 5 is opened. After the ice cream in the cylinder 4 is filled, it is placed again in the placement cylinder 8 and the sealing cover 5 is closed. When the sealing cover 5 is closed, the placement cylinder 8 moves downward and returns to the initial position by cooperating with the lifting mechanism, so that the ice cream scoop body 9 is completely moved into the water storage cylinder 7. After the sealing cover 5 is closed, the drainage effect of the open cover drainage mechanism on the inside of the water storage cylinder 7 is released, and clean water is transported to the inside of the water storage cylinder 7 through the action of the closed water inlet mechanism, so that the filling end of the ice cream scoop body 9 is immersed in the clean water in the water storage cylinder 7 for cleaning, ensuring that the ice cream adhered to the surface of the ice cream scoop body 9 is effectively cleaned before the next use, and through the cooperation of the closed water inlet mechanism and the open cover drainage mechanism, the clean water in the water storage cylinder 7 can be replaced each time the ice cream scoop body 9 is used, ensuring the cleaning effect and aesthetics of the ice cream scoop body 9, and reducing the impact of the repeated use of the ice cream scoop body 9 on the purchaser's desire to buy.
