Description

Technical Field

[0001] This invention relates to the field of thermos cups, specifically a temperature-controlled thermos cup. Background Technology

[0002] A thermos is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a lid that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping the water warm. A thermos is a cup that can keep the temperature of the drinking water in the cup changing slowly. A thermos consists of a cup body and a cup lid. There are double-walled thermos cups, vacuum thermos cups, and foam thermos cups, etc. The cup body of a double-walled thermos cup consists of an inner layer, an outer layer, and a gap between the inner and outer layers. The inner layer of the double-walled thermos cup is where the drinking water is placed. The gap in the double-walled thermos cup is filled with air. Air has a low density and is not good at conducting heat, so air is chosen as the insulation material.

[0003] However, when using a thermos, the water inside is often too hot to drink, causing burns. When drinking after it cools down, both the drinkable and undrinkable portions cool down, resulting in some water in the thermos completely cooling down and not reaching the desired drinking temperature. This necessitates adding or changing the water, leading to significant waste. Furthermore, it's difficult to control the overall cooling of the drinkable portion, potentially causing it to cool down excessively and reducing drinking comfort. Summary of the Invention

[0014] In summary, the beneficial effects of this invention are:

[0015] 1. This invention features a separate water separator inside the thermos to control the temperature of the drinking portion of the water from the remaining water. This allows for individual cooling and temperature control of the drinking portion while maintaining the temperature of the remaining water. When the water temperature is high, a control knob can be opened to accelerate the cooling of the drinking water in the separator. Once the temperature reaches a certain level, the thermos will maintain the temperature of the drinking portion, effectively preventing excessive cooling and thus achieving temperature control. This avoids scalding the drinker or causing the water to be too cold when drinking.

[0016] 2. If there is still water left in the dispensing chamber but you don't want to drink it anymore, you can turn the bottom cover clockwise to allow the hot water vapor in the thermos to enter the insulation chamber and keep the water in the dispensing chamber warm. This will ensure that the remaining drinking water in the dispensing chamber will still have a certain temperature when you drink it next time. Attached Figure Description

Detailed Implementation

[0029] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0030] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two elements or the interaction relationship of at least two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] The following is combined Figure 1-10 The present invention will be described in detail below. For ease of description, the directions referred to below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of front, back, left, right, up, and down in the view are consistent. Figure 1 The directions shown are consistent with the front-to-back, left-to-right, up-down directions of the device of the present invention when viewed from the front.

[0033] Please see Figure 1-10 This invention provides an embodiment of a temperature-controlled thermos cup, comprising a cup body 4 and a cup base 5. The inner end face of the upper region of the cup body 4 is provided with an inner annular groove 41, and the outer end face is provided with an outer annular groove 40. An annular mounting cavity 32 is provided in the adjusting base cover 3. The inner annular wall of the annular mounting cavity 32 is tightly embedded in the inner annular groove 41, and the outer annular wall of the annular mounting cavity 32 is tightly embedded in the outer annular groove 40, allowing the adjusting base cover 3 to rotate. The adjusting base cover 3 has a central... Air inlets 34 are evenly distributed on the bottom plate 33 of the part, and a central hole is provided through the center. A water distribution cylinder body 2 is provided in the adjusting bottom cover 3. The bottom of the water distribution cylinder body 2 fully abuts against the upper surface of the bottom plate 33. A water distribution cavity 20 is provided in the water distribution cylinder body 2. A heat preservation cavity 21 is provided on the lower side of the water distribution cavity 20. A water inlet pipe 25 is installed through the center of the bottom wall of the water distribution cavity 20. The water inlet pipe 25 passes through the central hole. A one-way valve 26 is fixedly installed in the water inlet pipe 25. The bottom end face of the water distribution cylinder body 2 is provided with air inlets 22 evenly distributed, each air inlet 22 extending through into the insulation cavity 21. Each air inlet 22 corresponds to a corresponding air inlet 34. The outermost two rings of air inlets 22 and air inlets 34 each have eight holes, and the innermost ring each has four holes, thus facilitating control of whether the connection is open or closed. On the upper end face of the adjusting bottom cover 3, two cylindrical parts 31 are fixedly provided. Two arc-shaped grooves 23 are provided at the bottom end of the protruding part on the side of the cylinder body 2. Each cylindrical part 31 is slidably embedded in the corresponding arc-shaped groove 23. When the adjusting bottom cover 3 is rotated counterclockwise, the cylindrical part 31 will drive the water distribution cylinder body 2 to rotate together. When the adjusting bottom cover 3 is rotated clockwise, the adjusting bottom cover 3 will rotate independently. This can control the connection between the second air inlet 34 and the first air inlet 22. In the initial state, the first air inlet 22 and the second air inlet 34 are not connected.

[0034] This allows drinking water to enter the water distribution chamber 20 through the inlet pipe 25 for a certain degree of cooling, while the remaining water in the thermos cup body 4 remains warm, making it convenient for people to drink. When the water temperature in the water distribution chamber 20 drops to the desired temperature, if you don't want it to drop any lower, you can turn the adjusting bottom cover 3 clockwise, which will rotate the bottom plate 33, thereby connecting the air inlet 22 and the air inlet 34. This allows hot water vapor from the thermos cup body 4 to enter the heat preservation chamber 21 to keep the water in the water distribution chamber 20 warm, thus controlling the water temperature of the drinking portion in the water distribution chamber 20.

[0035] The upper end of the main body 2 of the water distribution cylinder is equipped with a cup lid assembly for adjusting the cooling efficiency of the water inside the cup. The cup lid assembly includes a cup lid 1. An elastic plate 14 is provided in the right side area of ​​the inner cavity of the cup lid 1. The front and rear end faces of the elastic plate 14 slide against the inner wall of the cup lid 1. The upper end of the elastic plate 14 is rotatably connected to the top of the inner cavity of the cup lid 1. An end fixing plate 16 is fixedly connected to the lower end of the elastic plate 14. The end fixing plate 16 is slidably installed in the inner groove 15 in the exhaust cavity 17 opened on the right side. This creates a cavity between the elastic plate 14 and the inner wall of the cup lid 1. A soft airbag 13 is provided in the cavity. The bottom of the soft airbag 13 is fixed. On the elastic plate 14, the air inlet at the upper end of the soft airbag 13 is embedded in the adjustment hole opened at the top of the cup lid 1. A knob 12 is rotatably connected to the adjustment hole. An exhaust groove 10 is provided on the left side of the adjustment hole. A honeycomb exhaust hole component 11 is installed at the lower opening of the exhaust groove 10. A circular partition 101 is fixedly provided in the inner cavity of the cup lid 1. Through holes 102 are evenly distributed in the circular partition 101. Through holes 202 are evenly distributed in the top plate portion 201 of the water distribution cylinder body 2. Through holes 102 correspond to through holes 102. In the initial state, through holes 102 and through holes 202 are interconnected.

[0036] When you need to drink water, first turn the adjusting bottom cover 3 counterclockwise, which will cause the water distribution cylinder body 2 to rotate together, thus disconnecting the connection between the first through hole 202 and the second through hole 102. Then, invert the thermos cup, allowing the hot water in the thermos cup body 4 to enter the water distribution chamber 20 through the one-way valve 26. Then, invert the thermos cup back to its original position, so that the water distribution chamber 20 is full of the water you need to drink. At this time, turn the adjusting bottom cover 3 clockwise again to disconnect the connection between the first through hole 202 and the second through hole 102. Connect 102 and simultaneously release the top knob 12, turning it outwards. At this time, the hot water vapor in the water distribution chamber 20 enters the inner cavity of the cup lid 1 through the top connecting hole, causing the gas inside the cup lid 1 to expand and press the elastic plate 14 inwards to the right, causing the soft airbag 13 to contract. The gas inside the soft airbag 13 is then released into the exhaust groove 10 and ejected through the honeycomb exhaust hole 11. Simultaneously, the end fixing plate 16 slides to the right along the inner sliding groove 15. The movement causes the exhaust chamber 17 to open. The size of the opening is related to the contraction of the soft airbag 13. If the water temperature in the water distribution chamber 20 is high, more hot air is generated, and the soft airbag 13 contracts more, resulting in a larger opening. The greater the contraction of the soft airbag 13, the greater the airflow discharged through the honeycomb exhaust vent 11, thus carrying away all the hot air from the cup lid 1 through the exhaust chamber 17 to accelerate cooling. Conversely, when the water temperature in the water distribution chamber 20 is low, the generated hot air is insufficient to cool the cup lid 1. When the soft airbag 13 contracts, the exhaust chamber 17 does not open, thus maintaining a certain level of heat preservation. This allows the water temperature to be accelerated by opening the knob 12 when it is high, thereby accelerating the cooling of the water in the water distribution chamber 20. When the temperature drops to a certain level, the generated heat is insufficient to open the exhaust chamber 17, so heat preservation is maintained, thus ensuring the water temperature of the drinking portion. This effectively avoids the phenomenon of excessively low temperature, thereby achieving the purpose of temperature control and preventing scalding or excessively low water temperature when drinking.

[0037] It should be noted that, in order to facilitate people's drinking, a drinking spout 19 is installed on the left side of the cup lid 1. The drinking spout 19 is connected to the inner cavity of the cup lid 1, and the rubber nozzle on the outside of the drinking spout 19 is set at an upward tilt of 45°.

[0038] It is worth mentioning that in this embodiment, rubber protrusions 30 are evenly distributed on the outer end face of the adjustment base 3, which facilitates control of rotation and avoids scalding.

[0039] It should be noted that, in order to facilitate the water in the thermos cup to enter the water distribution chamber 20, in this embodiment, the bottom of the bottom plate 33 is provided to be in the shape of an inwardly concave arc, so that water can more easily enter the water distribution chamber 20 when the cup is inverted.

[0040] In another embodiment, an exhaust protection cover 18 is installed on the right end face of the cup lid 1 at the opening of the exhaust chamber 17. A honeycomb exhaust is added to diffuse and discharge the hot air, which can effectively prevent dust from entering and prevent the concentrated discharge of hot air from causing harm to people.

[0041] In another embodiment, the honeycomb exhaust vent 11 is funnel-shaped, and the air outlet of the honeycomb exhaust vent 11 faces the exhaust chamber 17, so that the airflow generated by the contraction of the soft airbag 13 is diffused and discharged, thereby increasing the airflow area and carrying away the generated heat.

[0042] In another embodiment, the diameters of the through hole 1 202 and the through hole 2 102 in the central region are smaller than the diameters in the outer region. The larger diameter of the outer holes facilitates the flow of water from the water distribution chamber 20 into the inner cavity of the cup lid 1 corresponding to the drinking spout 19 when drinking. The smaller diameter of the middle holes, however, is dense, thus not hindering the passage of hot air.

[0043] Initially, the first air inlet 22 and the second air inlet 34 are not connected, while the first through hole 202 and the second through hole 102 are interconnected.

[0044] When you need to drink water, first turn the adjusting bottom cover 3 counterclockwise, which will cause the water distribution cylinder body 2 to rotate together, disconnecting the connection between the first through hole 202 and the second through hole 102. Then, invert the thermos cup, allowing the hot water in the thermos cup body 4 to enter the water distribution chamber 20 through the one-way valve 26. Then, invert the thermos cup back to its original position, filling the water distribution chamber 20 with the water you need to drink. Now, turn the adjusting bottom cover 3 clockwise again to connect the first through hole 202 and the second through hole 102. At the same time, loosen the top knob 12 and pull it outwards. The hot water vapor in the water-distributing chamber 20 enters the inner cavity of the cup lid 1 through the top-connecting hole, causing the gas inside the cup lid 1 to expand and compress the elastic plate 14 to the right, causing the soft airbag 13 to contract. The gas inside the soft airbag 13 is then discharged into the exhaust groove 10 and ejected through the honeycomb exhaust hole 11. At the same time, the end fixing plate 16 slides to the right along the inner sliding groove 15, thereby opening the exhaust chamber 17. The size of the opening is related to the size of the contraction of the soft airbag 13. If the water temperature in the water-distributing chamber 20 is higher and more hot water is generated, the soft airbag 13 will contract more, and the opening will be smaller. The larger the air bladder 13, the greater its contraction, and the greater the airflow discharged through the honeycomb exhaust vent 11. This draws all the hot air from the cup lid 1 out through the exhaust chamber 17, accelerating cooling. When the water temperature in the water distribution chamber 20 is low, the generated heat is insufficient to cause the air bladder 13 to contract, so the exhaust chamber 17 remains closed, thus providing some insulation. This allows for faster cooling of the drinking water in the water distribution chamber 20 when the water temperature is high, by controlling the knob 12 to open. Once the temperature drops to a certain level, the generated heat is insufficient to open the exhaust chamber 17, thus maintaining the temperature. It can ensure the water temperature for the portion that needs to be drunk, effectively avoiding excessive cooling and thus achieving the purpose of temperature control. This prevents scalding or excessively cold water when drinking. If there is still water left in the water distribution chamber 20 but you don't want to drink it anymore, you can rotate the adjusting bottom cover 3 clockwise, which will rotate the bottom plate 33 and connect the first air inlet 22 and the second air inlet 34. This allows the hot water vapor in the thermos cup body 4 to enter the heat preservation chamber 21 to keep the water in the water distribution chamber 20 warm, so that the remaining drinking water in the water distribution chamber 20 will still have a certain temperature when you drink it next time.

[0045] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the invention. Therefore, the scope of protection of the invention should be determined by the scope defined in the claims.
