[0002] The structural design of the plastic thermos cup mainly includes the outer plastic material, the inner insulation layer, the sealing cover and the sealing ring. The outer plastic material has good heat resistance and cold resistance, can isolate the influence of the external temperature on the liquid in the cup, and has a leak-proof function. The inner insulation layer adopts low thermal conductivity materials, such as double-layer glass or stainless steel, to reduce the transmission of heat and maintain the temperature of the beverage. The sealing cover and the sealing ring ensure that the liquid will not leak out and maintain a stable temperature. However, during the use of the current plastic thermos cup, especially when there is hot water in the plastic cup and the user is in urgent need of drinking water, the hot water can only be cooled by continuous blowing to achieve the purpose of preventing the mouth from being scalded. However, frequently blowing the thermos cup to lower the temperature of the hot water is a relatively cumbersome operation, especially when the user is in urgent need of drinking water, it will greatly increase the waiting time and inconvenience of the user. Moreover, if the temperature is only cooled by external airflow, the surface temperature of the hot water will drop quickly, but the internal temperature changes relatively slowly, resulting in the uneven distribution of the temperature of the hot water inside the cup, and it is difficult to quickly reach the drinkable temperature.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides an embodiment: a plastic thermos cup, comprising a plastic cup body 1 and a cup head 2 screwedly mounted on the outer wall of the top opening of the plastic cup body 1, a cup cover 3 is hinged on the top of the cup head 2, a lock buckle 4 is arranged on the outer wall of the same side of the cup head 2 and the cup cover 3, a liquid outlet pipe 5 is fixed at the center position inside the cup head 2, and the bottom end of the liquid outlet pipe 5 extends to the inside of the plastic cup body 1 and is installed with a lower speaker isolation plate 6;

[0022] At least one drainage hole 10 is provided on the outer wall of the lower speaker isolation plate 6, and a sealing plate 7 for separating the plastic cup body 1 and the internal cavity channel of the liquid outlet pipe 5 is installed at one end of the liquid outlet pipe 5, and an arc-shaped drainage groove 11 is provided on the outer wall of the liquid outlet pipe 5 above the sealing plate 7. A plurality of first cooling plates 8 for exchanging heat with the liquid are evenly provided on the outer wall of the lower speaker isolation plate 6, and a channel for the liquid to flow through the first cooling plate 8 and enter the liquid outlet pipe 5 is formed between the drainage hole 10 and the arc-shaped drainage groove 11. On the one hand, the lower speaker isolation plate 6 cooperates with the sealing plate 7 to prevent the liquid from directly entering the liquid outlet pipe 5, and on the other hand, the lower speaker isolation plate 6 also serves to isolate the first cooling plate 8 from hot water, thereby reducing the heat exchange between the first cooling plate 8 and hot water during the placement of the cup body;

[0023] The plastic cup body 1 adopts a double-layer structure, and an air insulation layer is formed between the inner layer and the outer layer of the plastic cup body 1. The double-layer plastic cup body 1 forms an air layer between the inner and outer walls. Air is a good heat-insulating material and can effectively reduce the conduction of heat. Compared with a single-layer cup, a double-layer thermos cup can better maintain the temperature stability of the liquid and extend the heat preservation time, so that the hot drink can maintain the temperature for a longer period of time.

[0024] A holder 301 and a convex seat 201 are respectively installed on the outer wall of one side of the cup head 2 and the cup cover 3. A hinge shaft 302 for penetrating the holder 301 and the convex seat 201 is installed inside the holder 301. Torsion springs 303 are installed on both ends of the surface of the hinge shaft 302. When the user releases the connection between the cup head 2 and the cup cover 3 by the lock 4, the torsion spring 303 forces the hinge shaft 302 and the cup cover 3 to flip around the holder 301 as the center of the circle, that is, the cup cover 3 bounces up quickly, so that the cup body can be opened with one hand, so that the user can easily open the cup cover 3 with one hand, which is convenient and quick, and is especially suitable for situations where other items need to be taken at the same time or the thermos cup is used while walking, when walking or driving, etc.;

[0025] The top wall of the cup head 2 is fixed with a plurality of second cooling sheets 9 at equal intervals. The second cooling sheets 9 and the first cooling sheets 8 are both made of copper. The plurality of second cooling sheets 9 on the top wall of the cup head 2 serve to improve the heat exchange capacity and further accelerate the reduction speed of the water temperature.

[0026] A sealing ring 12 is installed on the top wall of the cup head 2. The cross-sectional shape of the sealing ring 12 is U-shaped. The sealing ring 12 ensures a higher degree of tightness between the plastic cup body 1 and the cup head 2, thereby enhancing the sealing of the thermos cup, effectively preventing liquid leakage, and maintaining a stable temperature of the liquid;

[0027] A trumpet mouth 501 is installed at the top of the liquid outlet pipe 5, a circular hole is opened at the center of the sealing disk 7, a sealing plug 701 is installed inside the circular hole, a column 702 is installed at the top of the sealing plug 701, the top of the column 702 extends to the inside of the trumpet mouth 501, and the outer diameter of the sealing plug 701 is less than or equal to the inner diameter of the trumpet mouth 501;

[0028] When the plastic thermos cup contains beverages containing solid particles, such as fruit particles or pearls in fruit tea, milk tea and other beverages, the user can remove the sealing plug 701 through the column 702, so that a through hole connected to the liquid outlet pipe 5 is generated at the center position of the sealing plate 7. The beverage and solid particles in the plastic cup body 1 can directly enter the liquid outlet pipe 5 and the trumpet mouth 501 through the lower trumpet isolation plate 6, ensuring smoothness and convenience of drinking, and the user does not need to worry about blockage problems.

[0029] When the embodiment of the present application is used, the staff first unscrews the cup head 2 from the top opening of the plastic cup body 1, and injects hot water or other liquids into it, and then re-screws the cup head 2. When the user drinks, the user releases the connection between the cup head 2 and the cup cover 3 through the lock buckle 4, and flips up the cup cover 3 to allow the liquid discharge tube 5 to leak out. After the user pours the plastic cup body 1, the liquid in the plastic cup body 1 flows into the lower speaker isolation plate 6 under the action of gravity. At this time, the hot water is blocked by the blocking plate 7 and cannot continue to be poured out, that is, the liquid can only enter the lower speaker isolation plate 6 through the drainage hole 10. , the plastic cup body 1 and the cup head 2 form a cavity, and exchange heat with a plurality of first cooling sheets 8 on the outer wall of the lower horn isolation plate 6. It is in direct contact with the hot water, and can effectively absorb heat from the hot water, so that its temperature gradually drops to a suitable drinking temperature. The cooled liquid enters the liquid outlet pipe 5 through the arc-shaped drainage groove 11, thereby achieving the purpose of preventing the mouth from being scalded. In this way, the user can easily enjoy hot water at a suitable temperature without frequently blowing on the thermos cup, which improves the convenience and comfort of use. In the process, the heat exchange is uniform and the cooling is rapid, ensuring a drinking experience at a suitable temperature.
