[0002] A water cup is a compact container designed to hold drinking water. Some water cups feature an innovative spout design, which is designed to prevent liquid splashing even when drinking in dynamic conditions, such as walking or exercising, ensuring elegance and cleanliness, and improving the drinking experience.

[0003] Some children's water cups now use a straw design, but young children often fail to fully realize the importance of assessing the temperature of the liquid in the cup due to their lack of common sense, and then try to drink it directly without first judging its heat. In this case, they may accidentally ingest a relatively high temperature liquid, which unfortunately causes burns to the mouth and digestive tract. Therefore, a new type of water cup for children is needed. Utility Model Content

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] See also Figure 1-5 A water cup for children includes a cup body 1 and a screw cap 2 threadedly connected to the opening of the cup body 1. The edge of the screw cap 2 is provided with a number of evenly distributed protrusions, and a vent is provided at the top of the screw cap 2. The protrusion of the screw cap 2 is convenient for hand twisting, and the setting of the vent facilitates the straw 3 to suck out the liquid in the cup body 1. The screw cap 2 is penetrated by a straw 3, and the bottom of the straw 3 is connected to a temperature control switch assembly 4. The suitable drinking liquid temperature for the human body is 10 to 40 degrees Celsius, and the highest drinking water temperature that the human body can tolerate is 60 degrees Celsius. Once it exceeds 65 degrees Celsius, it may scald the mucous membrane and increase the risk of esophageal diseases. When the liquid temperature is higher than 35 degrees Celsius, the temperature control switch assembly 4 begins to close, and when the liquid temperature is higher than 45 degrees Celsius, the temperature control switch assembly 4 is completely closed. A fixed ring 5 is fixedly sleeved at the top opening of the cup body 1, and the fixed ring 5 is rotatably connected to a flip cover 6. The flip cover 6 covers the straw 3, which improves the hygiene of the straw 3. The outer cover of the cup body 1 is provided with a heat-insulating cover 7, and the heat-insulating cover 7 is made of elastic heat-insulating material, such as rubber, woven mesh, etc.

[0027] The temperature control switch assembly 4 includes: a fixed shell 401 connected to the bottom of the suction tube 3, a fixed sleeve outside the fixed shell 401 is provided with a water inlet cage 403, and a rotating shell 402 is rotatably installed in the inner cavity of the fixed shell 401. The top water outlet of the rotating shell 402 is connected to the top pipe of the fixed shell 401. The outer wall of the rotating shell 402 is fixedly connected with a first spiral metal sheet 404 and a second spiral metal sheet 405 that are bonded together, and the fixed shell 401 is provided with an opening adapted to the rotation of the first spiral metal sheet 404 and the second spiral metal sheet 405. The first spiral metal sheet 404 and the second spiral metal sheet 405 are bonded together by welding, such as laser welding, explosion welding, continuous welding, etc. At the same time, the opening of the fixed shell 401 can limit the rotation angle of the first spiral metal sheet 404 and the second spiral metal sheet 405 to push the rotating shell 402. There is a certain distance between the first spiral metal sheet 404 and the second spiral metal sheet 405 and the inner cavity top wall and bottom wall of the water inlet cage 403, which is convenient for the flow of liquid. One end of the first spiral metal sheet 404 and the second spiral metal sheet 405 away from the fixed shell 401 is fixedly connected to the inner cavity side wall of the water inlet cage 403, and the fixed shell 401 and the rotating shell 402 are both provided with water inlet holes. The water inlet hole and the opening of the fixed shell 401 are respectively arranged on both sides thereof. When the liquid temperature is lower than 35 degrees Celsius, the free ends of the first spiral metal sheet 404 and the second spiral metal sheet 405 are restricted by the opening of the fixed shell 401 and are difficult to move, and the water inlet holes of the fixed shell 401 and the rotating shell 402 are completely connected. When the liquid temperature is higher than 35 degrees Celsius, the free ends of the first spiral metal sheet 404 and the second spiral metal sheet 405 jointly drive the rotating shell 402 to rotate, so that the water inlet holes of the fixed shell 401 and the rotating shell 402 are slowly staggered, until the liquid temperature is higher than 45 degrees Celsius, the water inlet holes of the fixed shell 401 and the rotating shell 402 are completely staggered, and the temperature control switch assembly 4 is completely closed.

[0028] The side wall of the water inlet cage 403 is provided with a plurality of evenly distributed through grooves. The through grooves of the water inlet cage 403 can perform preliminary filtering to reduce the blockage of the suction tube 3.

[0029] The first spiral metal sheet 404 is arranged on a side close to the fixed shell 401, and the second spiral metal sheet 405 is arranged on a side away from the fixed shell 401. The linear expansion coefficient of the first spiral metal sheet 404 is smaller than the linear expansion coefficient of the second spiral metal sheet 405. The first spiral metal sheet 404 and the second spiral metal sheet 405 are made of two different metal materials. When heated, the volume expansion of the second spiral metal sheet 405 is greater than that of the first spiral metal sheet 404, thereby driving the rotating shell 402 to rotate.

[0030] Working principle:

[0031] During use, hot water or other liquid beverages are injected into the cup body 1. When the temperature of the liquid is lower than 35 degrees Celsius, the free ends of the first spiral metal sheet 404 and the second spiral metal sheet 405 are restricted by the opening of the fixed shell 401 and are difficult to move. The water inlet holes of the fixed shell 401 and the rotating shell 402 are completely connected, and the temperature control switch assembly 4 is fully opened. When the temperature of the liquid is higher than 35 degrees Celsius, the free ends of the first spiral metal sheet 404 and the second spiral metal sheet 405 jointly drive the rotating shell 402 to rotate, so that the water inlet holes of the fixed shell 401 and the rotating shell 402 are slowly staggered, and the temperature control switch assembly 4 is gradually closed. Until the liquid temperature is higher than 45 degrees Celsius, the water inlet holes of the fixed shell 401 and the rotating shell 402 are completely staggered, and the temperature control switch assembly 4 is completely closed. After the temperature control switch assembly 4 is completely closed, the liquid in the cup body 1 cannot be sucked through the straw 3, thereby preventing children from directly inhaling high-temperature liquid into their mouths and scalding their mouths and digestive tracts.

[0032] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
