Description

Technical Field

[0001] The invention relates to a device for detecting the heat preservation performance of a thermos cup. Background Art

[0002] The thermal insulation performance of a thermos is the core indicator of its quality. Currently, the industry mainly uses the following two methods to test it: Manual detection: After pouring hot water into a thermos, the water temperature is manually measured using a thermometer at regular intervals (e.g., 6 or 12 hours). This method suffers from low efficiency, high human error, and the inability to continuously record data.

[0003] Simple testing equipment: Some companies use a combination of fixed temperature sensors and static environmental chambers, but this has the following drawbacks: Insufficient environmental control: Testing can only be done in a constant temperature environment, which cannot simulate real-world usage scenarios (such as temperature fluctuations); Single data dimension: only records temperature changes, lacks simultaneous monitoring of the cup sealing and external environmental parameters; Low detection efficiency: only one type of thermos cup can be tested at a time.

The solenoid valve 61 is controlled by the controller 1, and the tested thermos cup is loaded into the clamping device 3. By opening the solenoid valve 61, hot water and cold water are introduced into the clamping device 3. The opening of the solenoid valve 61 is adjusted by the controller 1 so that the temperature after the hot water and cold water are mixed is the required temperature for the test.

[0026] In the above technical solution, the thermos is sealed and clamped by a special clamping device 3. After the clamping is completed, the solenoid valve 61 is opened to allow the water in the hot water pipe 4 and the cold water pipe 5 to enter the clamping device 3.

The inner bottle body 312 is provided with a first solenoid valve 315, and the inner bottle body 312 is provided with a first solenoid valve 315. The inner bottle body 312 is provided with a first solenoid valve 315, and the inner bottle body 312 is provided with a first solenoid valve 315. The inner bottle body 312 is provided with a first solenoid valve 315, and the inner bottle body 312 is provided with a first solenoid valve 315.

The inner bottle body 312 is provided with a first solenoid valve 315, and the inner bottle body 312 is provided with a first solenoid valve 315. The inner bottle body 312 is provided with a first solenoid valve 315, and the inner bottle body 312 is provided with a first solenoid valve 315.

[0035] In the above technical solution, by designing the discharge pipe 314 and the first solenoid valve 315, the test water temperature needs to be adjusted during the test process. During the adjustment, the first solenoid valve is opened to a certain degree to discharge excess water until the first electronic thermometer 323 detects that the water temperature in the inner bottle body 310 reaches the test water temperature, and then the first solenoid valve 315 is closed.

[0036] In the above technical solution, an inner bottle body 310, a thermos bottle body 311 and an outer bottle body 312 are used in combination. The thermos bottle body 311 plays the role of external insulation, and the outer bottle body 312 is used to enter hot water. After the hot water enters, it is transported into the inner bottle body 310 in a ring shape. After the hot water rises, it is effectively mixed with the original water inside, making the test water temperature in the inner bottle body 310 more stable.

[0037] See Figure 2 、 Figure 4 and Figure 5 As shown, the sliding bottle cap structure 32 includes a bottle cap 3320 and an electric servo push rod 3321, the electric servo push rod 3321 is fixed to the vertical frame 21, the bottle cap 3320 is fixed to the movable end of the electric servo push rod 3321, and the bottle cap 3320 is pushed by the electric servo push rod 3321 to move downward and cooperate with the inner bottle body 310 to form a seal, and the electric servo push rod 3321 is controlled by the controller 1; a second electronic thermometer 3322 is installed on the top of the bottle cap 3320, and the measuring end of the second electronic thermometer 3322 is inserted into the inner bottle body 310, and the tested thermos cup is fixed to the bottom of the bottle cap 3320. When the tested thermos cup is fixed to the bottle cap 3320, the measuring end of the second electronic thermometer 3322 is located inside the tested thermos cup.

[0038] In the above technical solution, the bottle cap 3320 is separated from the inner bottle body 310 upward by the retraction of the electric servo push rod 3321, and the tested thermos cup is connected to the bottle cap 3320 in a spiral manner. After the connection is completed, the detection end of the second electronic thermometer 3322 is located inside the thermos cup, and liquid can be filled in the thermos cup.

[0039] The electric servo push rod 3321 is lifted up, so that the bottle cap 3320 moves downward and the inner bottle body 310 cooperates to form a seal.

[0040] At this point, the solenoid valve is opened again to allow hot and cold water to flow in. The hot and cold water mix until the set temperature is reached. After reaching the set temperature, since the outer wall of the thermos cup is in a cold state, the solenoid valve opening needs to be adjusted slightly at the beginning of the test to allow hot water to slowly enter the inner bottle body 310, so that the test temperature inside the inner bottle body 310 is stabilized at the desired test temperature. The solenoid valve is kept at a small opening for 2 minutes. During this period, the first solenoid valve is opened to a corresponding degree, allowing excess water to drain into the return tank. After the test temperature stabilizes, the solenoid valve and the first solenoid valve are closed.

[0041] When the first electronic thermometer detects that the test water temperature in the inner bottle body 310 is 3 degrees Celsius lower than the controller set temperature, the solenoid valve is reopened to replenish hot water.

[0042] See Figure 5 As shown, the bottom of the bottle cap 3320 is processed with an embedding part 3331, the bottom of the embedding part 3331 is processed with a conical matching surface 3332, and an annular groove is processed at the outer wall of the embedding part 3331, and a sealing ring 3333 is provided in the groove. The embedding part 3331 is embedded in the inner bottle body 310, and a seal is formed between the sealing ring 3333 and the inner wall of the inner bottle body 310. An internal threaded hole 3334 is processed at the bottom of the embedding part 3331, and the bottle cap to be tested is threadedly connected to the internal threaded hole 3334. The measuring end of the second electronic thermometer 3322 passes through the axis center of the internal threaded hole 3334.

[0043] In the above technical solution, the sealing performance of the bottle cap 3320 after assembly can be increased, thereby improving the heat preservation performance of the device itself.

[0044] See Figure 5 As shown, a first slot is processed at the inner top position of the internal threaded hole 3334, and a sealing block 3335 is clamped in the first slot. The diameter of the sealing block 3335 gradually decreases downward. When the thermos cup is threadedly connected to the internal threaded hole 3334, the sealing block 3335 is elastically deformed and embedded in the cup mouth of the thermos cup. The measuring end of the second electronic thermometer 3322 passes through the sealing block 3335, and the sealing block 3335 is elastically deformed to form a seal with the second electronic thermometer 3322.

[0045] In the above technical solution, the sealing block 3335 can increase the sealing with the cup mouth of the thermos cup after elastic deformation, and the sealing block 335 is squeezed and elastically deformed after being matched with the thermos cup, so that there is sufficient sealing between the second electronic thermometer 3322 and the sealing block 3335, avoiding inaccurate measurement caused by air circulation.

[0046] See Figure 5As shown, an annular sealing sheet 3336 is fixed to the bottom of the bottle cap 3320 . As the embedded portion 3331 is inserted into the inner bottle body 310 , the sealing sheet 3336 forms a seal with the upper end surface of the thermos bottle body 311 .

[0047] The sealing sheet 3336 is intended to further improve the thermal insulation effect.

[0048] See Figure 1 As shown, it also includes a display 199 for displaying real-time temperature. The display 199 is connected to the second electronic thermometer 3322 . The detected temperature of the second electronic thermometer 3322 is directly displayed via the display 199 . The display 199 is fixed on the vertical plate 21 .

[0049] The display 199 can display the temperature detected by the second electronic thermometer 3322 in real time.
