Description

Technical Field

[0001] The invention belongs to the technical field of intelligent hardware, and in particular relates to a heating and cooling thermos cup. Background Art

[0002] In recent years, with the improvement of the quality of life, people pay more and more attention to health, especially more and more people pay attention to disease prevention and healthy drinking water. Drinking warm water regularly helps prevent colds, pharyngitis, cerebral hemorrhage, myocardial infarction and certain skin diseases. In addition, gradually developing the habit of drinking warm water in daily life plays a significant role in protecting human health. Therefore, the demand for the use of thermos cups in travel, office and home life has been continuously strengthened, and the demand for the long-term heat preservation of thermos cups and the continuous provision of warm water has been increasing.

[0003] Common thermos cups only have the function of keeping warm, and the temperature of the warm water will continue to decrease over time and eventually turn into cold water. At the same time, only one cup of warm water when traveling is often not enough to meet the drinking needs of long-distance sports. At the same time, the water in the thermos cup is often boiled water, which can easily burn your hands and feet when you collect the water. In addition, the boiled water in the thermos cup needs to wait for a long time to cool down before you can drink the warm water. These are important factors that affect the satisfaction of the thermos cup experience.

[0004] At present, most thermos cups are insulated by double-layer glass or double-layer stainless steel. This type of cup is easy to burn your hands when adding boiling water, and it is not possible to drink quickly. The water in the cup will eventually turn into cold water, which leads to the risk of getting sick from drinking cold water. Some use alternating current to heat the cup to achieve the insulation effect. This cup can only be used at home or outdoors, and requires a large mobile power supply to heat it. Another problem is that this type of heatable thermos cup has a large base that takes up space in order to solve the problem of heating control components. The disadvantages of the above prior art are: 1. The storage cup is a double-layer integrated structure, which cannot heat or cool the water in the cup; 2. It needs to be connected to an external alternating current for heating, which is bulky, expensive, and inconvenient to carry when traveling.

[0005] Therefore, in order to solve the above problems, providing a thermos cup with heating and cooling is the subject to be studied by the present invention. It is necessary to add heating and cooling functions to the thermos cup, increase battery energy storage and battery usage time, so that users can continue to drink warm water or cooled ice water outdoors or indoors, so as to improve the user's quality of life experience, reduce the risk of illness caused by long-term drinking of cold water, and reduce the manufacturing cost of the thermos cup.

[0014] The relevant contents in the above technical solution are explained as follows.

[0015] 1. In the above scheme, the cup body is divided into a lower cup seat and an upper cup body; the lower cup seat includes a lithium battery pack, a lower cup seat shell and a lower cup seat bottom cover; several conductive metal contact posts are embedded in the bottom of the lower cup seat bottom cover, and the conductive metal contact posts are connected to the operation control circuit board through wires; two bottom cover magnets are fixed on the inner side of the lower cup seat bottom cover to facilitate the attraction with the external charging seat; the lithium battery pack is composed of several lithium battery cells combined in parallel or series to achieve sufficient power, and is supported and limited on the upper side of the induction coil by the limiting ribs of the lower cup seat bottom cover; the induction coil is located at the center of the inner circle of the lower cup seat bottom cover, and a pre-stressed shock-absorbing cotton is provided on the top to press the induction coil with the lithium battery pack so that the induction coil is closely attached to the lower cup seat bottom cover; the assembly of the operation control circuit board on the lower cup seat bottom cover is limited by the limiting ribs of the lower cup seat bottom cover; the fixing of the lower cup seat bottom cover and the lower cup seat outer shell is glued by glue, and a bottom cover overflow glue sealing groove is provided at the connection position of the lower cup seat bottom cover to prevent the glue from flowing out when gluing.

The shape of the airway is that the openings at both ends are large, the opening in the middle is small, and the side walls of the airway are arc-shaped; there is a concave surface on the bottom surface of the airway, and a raised circular concave platform is provided in the center of the concave surface.

[0017] 3. In the above scheme, the magnetic power fan blade is provided with two balancing magnets on the central symmetry line of the circle, which are fixed on the magnetic power fan blade by gluing, and an O-shaped magnet is fixed in the center. The magnetic poles of the three magnets are the same as the driving magnets and the main shaft magnets fixed behind the concave surface of the connecting ring, so as to realize the mutually repulsive force to drive and support the magnetic power fan blade; the blade of the magnetic power fan blade is formed by an even number of pairs of arc-shaped thin-walled ribs, which drive the gas around the heat sink fins to flow outward when the blade is rotated, so as to realize the heat dissipation function of the heat sink.

[0018] 4.

[0019] 5. In the above scheme, the semiconductor refrigeration sheet is a thermocouple formed by connecting a piece of N-type semiconductor material and a piece of P-type semiconductor material. When current passes through a thermocouple pair, heat transfer will occur between the two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference to form the characteristics of hot and cold ends; one side of the semiconductor refrigeration sheet is in contact with the heat sink, and the other side is connected to the stainless steel water cup through thermal grease.

[0021] 7. In the above scheme, the stainless steel water cup is divided into a stainless steel water cup body and a stainless steel water cup outlet ring; the outer shell insulation cavity is a closed cavity formed by connecting the stainless steel water cup, the upper cup body outer shell and the connecting ring. The heat on the stainless steel water cup body cannot be directly transferred to the upper cup body outer shell through other media. There is only air in the outer shell insulation cavity. The air has a low thermal conductivity and can be used to isolate heat transfer, thereby realizing the insulation function of the outer shell insulation cavity; the upper cup body outer shell, the connecting ring and the stainless steel water cup are fixed by gluing, and the connecting ring and the stainless steel outlet ring are provided with glue overflow grooves.

[0022] 8. In the above scheme, the handle cover heat insulation cavity is a cavity formed by the handle cover and the stainless steel water cup outlet ring after being tightened with the drinking water cover, and the low thermal conductivity of air can be used to isolate the transfer of heat, thereby realizing the heat preservation function of the handle cover heat insulation cavity. The sealing of the handle cover and the stainless steel water cup outlet ring is achieved by the mutual compression of the stainless steel water cup outlet ring and the handle cover sealing gasket on the inner top surface of the handle cover during the tightening process.

[0023] 9. In the above scheme, the water suction pipe can be extended 1 to 2 times in length by two folded ring walls that open outward and stretch in a superimposed manner when pulled outward. The drinking water cover is provided with a water inlet; the drinking water cover is provided with a silicone connecting cover, which is divided into a water suction pipe silicone cover and a water inlet silicone cover and is respectively covered on the water suction inlet and the water inlet; the drinking water cover is fixed and sealed by mutual extrusion with the outlet ring of the stainless steel water cup through an O-ring.

[0024] 10. In the above scheme, the handle bracket is limited on the handle cover by the handle rotating shaft and the hook-shaped limiting rod; the handle bracket can support tilted objects, and the line texture on the top of the handle cover is used to prevent the tilted objects from sliding, and the object placement area formed when the handle bracket is rotated to a certain angle can effectively prevent any tilted objects from sliding; after the hook-shaped limiting rod is mutually limited with the handle bracket when rotating to a certain angle, the opened hook-shaped limiting rod can hook a certain light object. The handle opening on the handle bracket is convenient for picking up the cup body.

[0025] The working principle and advantages of the present invention are as follows.

[0026] 1. The charging method of the lithium battery samples wired and wireless charging solutions and is implemented on a lower cup holder bottom cover, which is convenient for charging flexibility. At the same time, a lithium battery pack composed of multiple cells can provide sufficient power for the insulation of the cup body. The ribs of the lower cup holder bottom cover are used as limiters for the lithium battery pack and the operation control circuit board, which can realize multi-function and effectively reduce the space of the lower cup holder.

[0027] 2. Through the semiconductor refrigeration sheet, the heat transfer tool is utilized. When the current flows through the thermocouple formed by a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends. The heat will be transferred from one end to the other end, thereby generating a temperature difference to form the characteristics of the hot and cold ends. This characteristic is utilized to heat or cool the stainless steel water cup, realize the heat preservation function of the cup body and the cooling function of the stainless steel water cup body, so that you can drink warm water multiple times or in a short time.

[0028] 3. The airway side wall of the connecting ring is set to be in an arc shape, and the airway shape is formed with large openings at both ends of the airway and a small opening in the middle, which is convenient for gas to pass through the airway. At the same time, when the heat of the semiconductor refrigeration chip is transferred to the heat sink, the high-heat area will be transferred to the heat sink fins of the heat sink to transfer heat with the surrounding air. The temperature difference caused by the uneven heating of the air in the airway, the hot air is light and rises, and the cold air flows to supplement it, forming a convective gas to achieve the cooling function of the heat sink.

[0029] 4. The magnetic power fan blades rotate under the mutual repulsion of the driving magnet at the bottom of the connecting ring and the same magnetic poles of the balancing magnet on the magnetic power fan blades. No additional power is needed to drive the magnetic power fan blades. When the magnetic power fan blades rotate, the gas in the airway is thrown out. During the flow of gas, the heat of the heat sink fins is taken away and the heat dissipation function is realized. This solves the problem that the heat generated at the other end of the semiconductor refrigeration plate when cooling the stainless steel water cup body cannot be dissipated, resulting in overheating of the outer wall of the connecting ring. At the same time, it speeds up the cooling speed when adding boiling water into the stainless steel water cup, so that the time for drinking warm water can be achieved quickly.

[0030] 5. When the temperature at the other end of the semiconductor refrigeration chip is too high, the heat sink cannot dissipate the temperature in time. The heat transfer causes the temperature of the connecting ring to be too high, which can easily scald the user. At this time, the radiator temperature sensor on the side of the heat sink is used to monitor the temperature on the heat sink. The software algorithm is used to control the length of time the semiconductor refrigeration chip cools the stainless steel water cup, so as to reduce the excessive temperature of the semiconductor refrigeration chip that affects the surface temperature of the connecting ring.

[0031] 6. The water temperature in the stainless steel water cup is monitored by the temperature sensor of the water cup body. At the same time, the semiconductor refrigeration chip is controlled by the software algorithm to automatically control the heating or cooling of the stainless steel water cup, thereby ensuring that the water temperature can be stabilized within a temperature value to achieve a long-term heat preservation effect. In addition, the digital tube can display the current water temperature value in the cup in real time, allowing users to observe the water temperature more intuitively.

[0032] 7. The outer shell insulation cavity forms a circular air cavity through the upper cup shell, the stainless steel water cup and the connecting ring. In the absence of other connecting media, the heat on the stainless steel cup body can be reduced and transferred to the cup shell through the medium, thereby achieving the insulation function. In addition, by monitoring the temperature of the radiator and the stainless steel water cup body, the software algorithm is used to control the semiconductor refrigeration sheet to heat or cool the stainless steel water cup body to achieve a constant temperature, thereby achieving a double-layer insulation effect.

[0033] 8. The top of the drinking cover is equipped with a foldable suction tube, which can be extended 1 to 2 times in length to facilitate drinking and prevent the user's mouth from colliding with the outlet ring of the stainless steel cup. At the same time, the drinking cover can prevent the user from choking due to the excessive opening of the outlet ring of the stainless steel cup when drinking water. The suction tube can be folded back to facilitate the covering of the handle cover to reduce the space in the cup body; an insulating cavity of the handle cover is formed between the drinking cover and the handle cover, which can effectively prevent the heat of the water in the cup body from being directly transferred to the outside through the single-layer cover, thereby better realizing the insulation function.

[0034] 9. The drinking cap and the stainless steel water cup are sealed and fixed by squeezing the O-ring. The drinking cap can be quickly disassembled by buckling the water inlet inward and then pulling it out. The drinking cap can be removed to clean the remaining stains in the stainless steel water cup.

[0035] 10. The bottom cover of the lower cup holder, the connecting ring and the outer connecting position of the stainless steel water cup outlet ring are all equipped with glue storage sealing grooves, which can effectively seal the connecting positions when the glue is connected to each part to prevent liquid from entering the cup body during the cleaning process and causing a short circuit in the electronic devices. The glue storage sealing groove can prevent the glue from overflowing when bonding the glue. At the same time, the high glue content in the glue sealing groove can enhance the firmness of the bonding. At the same time, the touch switch can facilitate user operation and can put the cup body in the sink for cleaning, which can effectively prevent water from entering the cup body.

[0036] 11. When the handle bracket is rotated to a certain angle, the line texture on the top of the handle cover is used to increase the roughness of the top of the handle cover, and objects placed obliquely on the handle cover and leaning on the handle bracket will not slip. The handle bracket is convenient for users to pick up the cup body through the handle opening. In addition, rotating the hook-shaped limit rod to a certain angle can be used to hook some light objects for use, thereby realizing the multi-functional role of the handle bracket.

The two balancing magnets 30 are fixed to the magnetic power fan blade 20 by means of adhesive. An O-shaped magnet 31 is fixed in the center. The magnetic poles of the three magnets are the same as the magnetic poles of the driving magnet 29 fixed by the connecting ring 3, so as to realize the mutually repulsive force to drive the magnetic power fan blade 20. The blade 64 of the magnetic power fan blade 20 is formed by an even number of pairs of arc-shaped thin-walled ribs, which drives the gas to flow outward when the blade 64 is rotated. The support shaft 32 passes through the O-shaped magnet 31 of the magnetic power fan blade 20 and is positioned inside the circular concave platform 48. The top of the support shaft 32 is pressed by the heat dissipation fin 63 so that the magnetic power fan blade 20 is located on the middle bottom surface of the airway 40. The support shaft 32 is used as a limit shaft when the magnetic power fan blade 20 rotates.

[0045] according to Figure 5 , 6When the magnetically powered fan blades 20 rotate clockwise, the gas enters from the air duct 40 on the right side of the connecting ring 3 and passes through the heat dissipation fins 63. At the same time, under the action of the magnetic force, the fan blades 64 drive the gas to be thrown out to the left side of the connecting ring 3. Under the shape of the concave surface 47, the gas will pass through the heat dissipation fins 63 again. In addition, when the heat dissipation fins 63 transfer heat to the surrounding air, the air in the air duct 40 is heated unevenly and causes a temperature difference. The hot air of the concave surface 47 is light and rises, and the cold air flows to supplement the concave surface 47, forming convection to accelerate the rotation of the fan blades 64. At this time, the high-temperature gas around the heat dissipation fins 63 will continuously throw the fan blades 64 out of the left side of the connecting ring 3, thereby realizing the heat dissipation function of the heat dissipation fins 63.

[0046] The heat sink 33 has a heat conducting plane 62 on one side, which is in contact with the semiconductor refrigeration sheet, and a heat dissipation fin 63 on the other side. When the heat sink 33 is installed in the connecting ring 3 and fixed in position, the heat dissipation fin 63 extends into the air passage 40, so that the heat on the heat sink 33 is transferred to the flowing gas through the heat dissipation fin 63. A square groove 61 is provided at the fixing position of the connecting ring 3 and the heat sink 33, and the square groove 61 facilitates the fixing of the connecting ring 3 and the heat sink 33 by gluing.

[0047] One side of the semiconductor refrigeration sheet 35 is in contact with the heat-conducting plane 62 of the heat sink 33, and the other side is connected to the bottom of the stainless steel water cup body 12 through thermal grease. The thermal grease can eliminate the processing error and flatness of the stainless steel water cup. The heat preservation of the cup body 100 is to heat the stainless steel water cup 5 through the characteristics of the semiconductor refrigeration sheet 35. The water cup body temperature sensor 16 is used to control the heating or cooling time of the semiconductor refrigeration sheet 35. The radiator temperature sensor 34 is used to control the cooling time of the stainless steel water cup body 12 by the semiconductor refrigeration sheet 35 to avoid the side wall temperature of the connecting ring 3 being too high.

[0048] The stainless steel water cup 5 is divided into a stainless steel water cup body 12 and a stainless steel water cup outlet ring 13. The stainless steel water cup outlet ring 13 is an annular interface formed by film injection molding. Two circles of stainless steel water cup outlet ring glue storage sealing grooves 17 are arranged on the lower outer ring of the stainless steel water cup outlet ring 13. The shell heat insulation cavity 42 is a closed cavity after the stainless steel water cup 5, the upper cup body shell 4 and the connecting ring 3 are connected to each other. The heat on the stainless steel water cup body 12 of the stainless steel water cup 5 cannot be directly transferred to the upper cup body shell 4 through other media. There is only air in the shell heat insulation cavity 42. The air has a low thermal conductivity and can be used to isolate the transfer of heat, thereby realizing the heat preservation function of the shell heat insulation cavity 42; the upper cup body shell 4 is fixed to the connecting ring 3 and the stainless steel water cup 5 by gluing, and the stainless steel water cup 5 and the upper cup body shell 4 are gluingly connected through the stainless steel water cup outlet ring glue storage sealing groove 17.

[0049] according to Figure 4The fixing and sealing of the drinking water cover 22 is achieved by the mutual extrusion of the O-ring 21 and the outlet ring side wall 43, and the drinking water cover 22 is stuck on the upper side of the stainless steel water cup outlet ring 13. The handle cover heat insulation cavity 41 is a cavity formed by the handle cover 6 and the stainless steel water cup outlet ring 13 and the drinking water cover 22 after being tightened. The low thermal conductivity of air can be used as a heat insulation to achieve the heat preservation function of the handle cover heat insulation cavity 41. The handle cover sealing gasket 14 is on the top surface of the handle cover 6. During the tightening process of the handle cover 6 and the stainless steel water cup outlet ring 13, the handle cover sealing gasket 14 and the stainless steel water cup outlet ring 13 are pressed against each other to achieve a sealing effect.

[0050] according to Figure 7 The water suction pipe 50 can be extended 1 to 2 times in length by two folded ring walls 49 that open outward and stretch in a superimposed manner when pulled outward. The drinking water cover 22 is provided with a water inlet 53; the drinking water cover 22 is provided with a silicone connecting cover 23, which is divided into a water suction pipe silicone cover 51 and a water inlet silicone cover 54 and covers the water suction port 52 and the water inlet 53 respectively; the O-ring 21 is buckled in the U-shaped groove on the side edge of the drinking water cover 22, and the U-shaped groove prevents the O-ring 21 from falling out of the drinking water cover 22 during the assembly and removal of the drinking water cover 22 and the stainless steel water cup outlet ring 13.

[0051] according to Figure 8 The handle bracket 7 is limited on the handle cover 6 by the handle rotating shaft 37 and the hook-shaped limiting rod 36; the handle bracket 7 can support tilted objects, and the top line texture 55 of the handle cover 6 is used to prevent the tilted objects from sliding, and when the handle bracket 7 rotates to a certain angle, the handle bracket limiting boss 58 and the handle cover concave surface 59 are mutually limited, at this time, the handle bracket 7 can no longer rotate and form an object placement area 56, and the object placement area 56 can effectively prevent any objects placed on the handle bracket 7 at an angle from sliding. When the hook-shaped limiting rod 36 rotates to a certain angle, the rotating shaft limiting boss 60 is limited with the handle bracket 7, and at this time, the hook-shaped limiting rod 36 can hook some objects placed outside. The handle opening 57 on the handle bracket 7 is convenient for the user to pick up the cup body 100 by extending his fingers through the handle opening 57.

[0052] Embodiment 2: See attached Fig.12 As shown, the rest is the same as the first embodiment, except that: the connecting ring 2 65 does not have the pre-embedded driving magnet 29 and the concave surface 47, the radiator 66 does not have the structural shape of the cooling fins 63, the airway 2 67 does not have the magnetic power fan blades 20, and one surface of the radiator 66 will be at the top of the airway 2 67.
