Description

Double-cavity vacuum cup

Technical Field

The invention relates to the technical field of vacuum cups, in particular to a double-cavity vacuum cup.

Background

The vacuum cup is a cup capable of slowly reducing the temperature of drinking water in the cup, and comprises a cup body and a cup cover. The vacuum cup with good working performance can slow down and even block the heat transfer between the liquid in the cup and the outside, achieves the effect of keeping the temperature of the liquid in the cup for a longer time, and provides convenience for storing and drinking the liquid with different temperatures. Common vacuum cups for drinking water include two types, namely double-layer vacuum cups and vacuum cups. The cup body of the double-layer vacuum cup comprises an inner layer, a shell and a gap layer (gap) between the inner layer and the shell, wherein the inner layer of the double-layer vacuum cup is a place for containing drinking water, and the gap layer of the double-layer vacuum cup is filled with air, so that the air density is low, the heat transfer is difficult, and the air is a heat insulation material. The vacuum cup is a vacuum cup, and the vacuum cup has the advantages that the vacuum cup is not conducted in vacuum and has good heat preservation performance due to no convection. The foam vacuum cup is a vacuum cup with an air foam insulating layer.

Although the thermos cup brings convenience to life of people, the function of the traditional thermos cup is only limited to delay heat exchange of solution in the cup body, and the thermos cup has singleness and has various inconveniences and insecurities in the use process. The best known hot water brewing temperature of coffee is 85 degrees, the best hot water brewing temperature of tea is generally above 90 degrees, and the recommended temperature of coffee liquid or water at a drinking port is generally 55-65 degrees. For the liquid such as boiling hot water, tea, coffee and the like which is just poured in, people usually need to have a long waiting time when drinking so as to wait for the temperature of the liquid in the cup to drop, and if drinking too hot water for a long time, the digestion system is not favorable. Because the thermos cup has good heat preservation effect, in order to obtain the temperature suitable for drinking as soon as possible, people can open the lid with the thermos cup and dispel the heat usually, and the thermos cup that the lid was opened and is placed falls because of the mistake easily, takes place the accident.

In order to solve the problem that liquid with proper temperature needs to be drunk in a short time, a heat phase change heat absorption material technology is adopted in the prior art, a phase change energy storage material capable of absorbing heat is added into a gap layer, and the heat of the liquid in the cup is rapidly absorbed through shaking so as to reduce the temperature. However, almost half of the space of the vacuum cup is used for storing the phase change energy storage material, almost half of the space is left for containing liquid, and the cup body is heavy. Meanwhile, the temperature of the vacuum cup is reduced by simultaneously reducing the temperature of all liquid in the cup, so that the long-acting heat preservation function of the vacuum cup is lost. In addition, after the vacuum cup is used for the first time, if the vacuum cup is used again in a short time, the temperature reduction effect is poor because the phase change energy storage material cannot release heat to be reduced to the room temperature. In addition, when hot water is added, a user often cannot see the hot water until the hot water is filled, so that the hot water is easy to overflow, and the user is scalded.

Therefore, there is a need for a thermos cup that can rapidly lower the temperature of the liquid to be drunk while maintaining a long-term insulation, so as to make it suitable for drinking and safe, which is also overlooked and lacking in the prior art.

Referring to fig. 4-6, wherein fig. 4 is a perspective view of the outer cover of the first embodiment of the dual-cavity vacuum cup of the present invention, fig. 5 is a top view of the embodiment of fig. 4, and fig. 6 is a cross-sectional view of the embodiment of fig. 4. In this embodiment, the outer lid 40 is adapted to be sealingly connected to the second cavity of the cup body, and a passage sealing plug 49 is provided in the outer lid 40 for opening or sealing the liquid passage 13

The outer cover 40 is provided with a first lever mechanism 41, a first drinking hole 42 and a first drinking switch button 43 which are oppositely arranged, and a passage sealing plug 49 is connected with the outer cover 40 through an elastic part 491. In the first lever mechanism 41, the power arm 411 is connected to the first drinking switch button 43, and a first air inlet hole 419 for communicating the first cavity 11 with the outside air is formed in the power arm, the lever center shaft 412 is fixed to the outer cover 40, and a first sealing plug 418 for sealing the first drinking hole 42 is formed in the resistance arm 413. A connecting rod 414 is fixedly connected below the power arm 411 of the first lever mechanism 41, the lower end of the connecting rod 414 is in press-connection with a power arm 4151 of a first sub-lever mechanism 415, a lever middle shaft 4152 of the first sub-lever mechanism 415 is fixed on the outer cover 40, a resistance arm 4153 of the first sub-lever mechanism 415 is connected with the passage sealing plug 49, and the first sub-lever mechanism 415 compresses or expands through an elastic component 491 driving the passage sealing plug 49 to open or seal the liquid passage 13. The resistance arm 4153 of the first sub-lever mechanism 415 can be movably connected with the passage sealing plug 49, at this time, a protrusion can extend outwards from the passage sealing plug 49 near the elastic member 491, and a corresponding protrusion also extends from the resistance arm 4153 of the first sub-lever mechanism 415 to clamp the passage sealing plug 49, so as to ensure that the passage sealing plug 49 can only be driven by the elastic member 491 and the resistance arm 4153 to move up and down; thereby causing the elastic member 491 of the passage sealing plug 49 to compress to open the liquid passage 13 when the resistance arm 4153 of the first sub-lever mechanism 415 moves upward, and the elastic member 491 of the passage sealing plug 49 falls back and expands downward to close the liquid passage 13 when the resistance arm 4153 of the first sub-lever mechanism 415 moves downward. Resistance arm 4153 of first sub-lever mechanism 415 may also be fixedly connected to passage seal plug 49.

That is, the opening (pressing)/sealing (lifting) of the first drinking switch button 43 on the cover controls the passage sealing plug 49 to open/seal the passage for the liquid communication between the two chambers. The elastic member 491 may be a spring.

It is preferred. The passage sealing plug 49 can be a telescopic or sectional passage sealing plug, so that inconvenience caused by too long a passage sealing plug is avoided, and the use experience of a user is improved.

Specifically, when the first drinking switch button 43 (i.e., the warm water switch button) is pressed, the power arm 411 of the first lever mechanism 41 moves downward to drive the resistance arm 413 of the first lever mechanism 41 to move upward, so that the first sealing plug 418 is lifted to open the first drinking water hole 42, and the first air inlet hole 419 allows external air to enter the first cavity 11; meanwhile, the power arm 411 of the first lever mechanism 41 drives the connecting rod 414 to move downwards, the connecting rod 414 drives the power arm 4151 of the first sub-lever mechanism 415 to move downwards, and the power arm 4151 of the first sub-lever mechanism 415 drives the resistance arm 4153 of the first sub-lever mechanism 415 to move upwards, so as to drive the elastic part 491 of the passage sealing plug 49 to compress to open the liquid passage 13; after the high-temperature liquid flows into the first cavity 11 from the second cavity 12 through the liquid passage 13 and dissipates heat, the liquid with a proper temperature can flow out from the first drinking water hole 42 (i.e., the warm water outlet) for a user to drink. Lifting the first drinking switch button 43, the power arm 411 of the first lever mechanism 41 moves upwards, and drives the resistance arm 413 of the first lever mechanism 41 to move downwards, so that the first sealing plug 418 falls down to close the first drinking hole 42; meanwhile, the power arm 411 of the first lever mechanism 41 drives the connecting rod 414 to move upwards, the connecting rod 414 drives the power arm 4151 of the first sub-lever mechanism 415 to move upwards, and the power arm 4151 of the first sub-lever mechanism 415 drives the resistance arm 4153 of the first sub-lever mechanism 415 to move downwards, so as to drive the elastic component 491 of the channel sealing plug 49 to extend to close the liquid channel 13; no liquid flows between the second chamber 12 and the first chamber 11.

Preferably, the outer cover 40 is further provided with a second lever mechanism 44, a second drinking hole 45 and a second drinking switch button 46 which are oppositely arranged. In the second lever mechanism 44, the power arm 441 is connected to the second drinking switch button 46, and a second air inlet hole 449 for communicating the second cavity 12 with the outside air is formed thereon, the lever central shaft 442 is fixed to the outer cover 40, and the resistance arm 443 is provided with a second sealing plug 448 for sealing the second drinking hole 45.

Specifically, when the second drinking water switch button 46 (i.e. hot water switch button) is pressed, the power arm 441 of the second lever mechanism 44 moves downward to drive the resistance arm 443 of the second lever mechanism 44 to move upward, so that the second sealing plug 448 is lifted to open the second drinking water hole 45, and the second air inlet hole 449 allows external air to enter the second cavity 12, i.e. to flow out liquid with higher temperature from the second drinking water hole 45 (i.e. hot water outlet). When the second drinking switch button 46 is lifted, the power arm 441 of the second lever mechanism 44 moves upward to drive the resistance arm 443 of the second lever mechanism 44 to move downward, so that the second sealing plug 448 falls down to close the second drinking hole 45, thereby ensuring the sealing, leakage-proof and heat-preserving effects of the water cup. In other embodiments, the cover 40 may have only one drinking hole in the lever manner, for example, the hot water outlet may be a simple plug or a toggle switch on a commercially available cup cover, since the hot water does not need to be drunk while opening the liquid passage connecting the first and second chambers.

When a user uses the double-cavity vacuum cup, the outer cover 40 is unscrewed, the second water outlet hole 212 at the upper part of the second cavity 12 of the vacuum cup body can be used for conveniently pouring liquid, and the outer cover 40 is screwed after the user adds the liquid with the temperature required to be kept; when the user needs to drink warm water, the user can drink a few mouths of liquid with a volume suitable for drinking after being cooled in the first cavity 11 through the first drinking hole 42 by pressing the first drinking switch button 43 on the outer cover 40; then, the high-temperature liquid in the second cavity 12 flows into the first cavity 11 through the liquid channel 13 for supplement, and the high-temperature liquid performs rapid heat dissipation and cooling in the first cavity 11, so that the circulation is performed, and the user can continuously drink the liquid with the temperature suitable for drinking. When hot water is needed, the second drinking switch button 46 on the outer cover 40 is pressed, and the high-temperature liquid in the second cavity 12 flows out through the second drinking hole 45. When the cup is not needed to be drunk, the buttons on the outer cover are all in a sealing state, and the sealing, leakage prevention and heat preservation effects of the cup can be guaranteed. The second cavity 12 is vacuum heat-insulated, so that heat dissipation of high-temperature liquid can be effectively prevented, long-acting heat preservation of liquid in the vacuum cup is guaranteed, and the drinking time of the liquid in the whole vacuum cup is prolonged.

Preferably, the outer cover may be provided with a sealing switch for controlling the expansion and contraction of the passage sealing plug. Pressing or rotating the sealing switch can retract the passage sealing plug, and pressing or rotating the sealing switch can extend the passage sealing plug to the original position. In winter, the warm water in the first cavity can become cold water after a long time, and the water in the second cavity is still very hot. Through add sealed switch on the enclosing cover, increase and to let hot water and cold water mix harmonious function, convenience of customers decides whether need change the temperature through mixing. Specifically, the cup body is inclined downwards at the upper warm water outlet of the inner cover and one side of the liquid channel until the upper warm water outlet of the inner cover is downward; because a relatively large space is formed among the inner cover, the second cavity and the first cavity, and a relatively large space is also formed between the outer cover and the inner cover, most of or even all of the liquid in the first cavity can flow into the space; then, press or rotatory sealing switch can make the passageway sealing plug retract for hot water can flow out from the liquid passage and get into first cavity in the second cavity, mixes with the cold water in the first cavity, thereby forms the warm water of suitable temperature and supplies the use. Preferably, the outer cover is further provided with a temperature sensor for displaying the liquid temperature of the first cavity and the second cavity.

Preferably, the bottom of the first cavity can be provided with a convex sealing switch for opening or sealing the liquid channel at the bottom of the second cavity. The liquid flow path can be sealed from the bottom by pressing or rotating the sealing switch, and the bottom of the liquid flow path can be opened by pressing or rotating the sealing switch. Therefore, if a user does not want to use the warm water function of the first cavity, the water inlet part of the first cavity can be closed, and the heat preservation function of the second cavity is only used. At this time, the outer cover can adopt a water cup cover sold in the market, and a passage sealing plug for opening or sealing the liquid passage is not required to be arranged.

Referring to fig. 7, the schematic diagram of the water full-proof prompt valve of the present invention includes a schematic diagram of a non-prompt state on the left side and a schematic diagram of a water full-proof prompt state on the right side. The water full-proof prompt valve comprises a buoy 701, a rotating shaft 703 and a metal hammer 704. The buoy 701 is much lighter than water as a whole and can be air inside; the buoy 701 is larger in volume and gravity than the metal hammer 704. The metal hammer 704 is a small hammer that strikes the cup mouth to produce sound. The rotating shaft 703 is a small rotating shaft with two protruding sides, and the protruding part of the rotating shaft 703 is hung at the cup opening of the second cavity in a non-prompting state (the cup opening can be provided with steps or corresponding grooves, so that the rotating shaft 703 can be conveniently placed). Due to the eccentric neutral design, and the volume and gravity of the float 701 are both larger than those of the metal hammer 704, when the float 701 is in a lower position in a non-prompting state (no water or the water is not full), the metal hammer 704 is in an upper position (not contacting the cup mouth), and the float 701 is basically in a vertical state and is not easy to see. When hot water is poured into the cup, the buoy 70 floats to drive the rotating shaft 703 to rotate, so that the metal hammer 704 falls down, the buoy 70 becomes a plane 702 which is easy to see, the plane 702 is thin and can be warned by bright colors (such as red), so as to remind a user to stop pouring the water immediately, and meanwhile, the metal hammer 704 can knock on the cup, so as to make a sound to further remind the user. Wherein the metal hammer 704 may be absent.

In addition, the extension of the inner cover of the invention is higher than the plane of the inner cover, so that even if the user slowly reflects, overflowed water can be absorbed by the inner cover through the water outlet of the inner cover and enters the first cavity. The first cavity body flows into liquid through the liquid channel of the second cavity body, so that the liquid flows slowly, and even if the water which overflows from the absorption part is not filled as fast as the second cavity body.

Referring to fig. 8-10, wherein fig. 8 is a sectional view of a second embodiment of the dual-cavity vacuum cup of the present invention, fig. 9 is a schematic view of the water discharged from the first cavity after the outer cover is unscrewed in the embodiment of fig. 8, and fig. 10 is a schematic view of the water discharged from the second cavity after the outer cover is unscrewed in the embodiment of fig. 8.

In the embodiment, the liquid passage 83 is disposed on the bottom of the second cavity 82 at the same side of the first outlet hole 851 (i.e., the warm water outlet hole) of the inner lid 85, and the liquid passage 83 is a tapered slope 831; the inclined plane can prevent tea leaves, coffee grounds and the like from flowing into the liquid channel and is convenient to clean. The liquid channel 83 is disposed at the bottom edge of the second cavity 82, so that when warm water is drunk through the first cavity 81, the hot water in the second cavity 82 is not easy to flow out.

In this embodiment, the passage sealing plug 89 is a telescopic segmented passage sealing plug, and includes a first cylinder 891, a second cylinder 892 and a plug 893, where the first cylinder 891 is connected to the outer cover 86, the second cylinder 892 is non-cylindrical and rigidly connected to the inner wall of the bottom of the second cavity 82, one end of the plug 893 is sleeved on the second cylinder 892 and movably connected to the first cylinder 891, and the other end of the plug 893 is a sealing surface adapted to the tapered slope 831 of the liquid passage 83. The first cylinder 891 may be one piece or segmented (the segmented pattern allows the passage seal plug 89 to be shorter). When the first cylinder 891 moves downward, the sealing surface of the plug 893 is moved downward, so that the sealing surface of the plug 893 makes seamless contact with the tapered slope 831 of the liquid passage 83, and the liquid passage 83 is sealed to block the convection of the first chamber 81 and the second chamber 82.

The second post 892 may be a vertical, non-cylindrical, thin post rigidly attached to the inner wall of the second chamber 82 and strong enough to not easily bend and thereby conform to the shape of the corresponding hollow core portion of the plug 893 to prevent rotation of the plug 893. The plug 893 is a whole that can be taken out, which is convenient for cleaning and the shape is not limited; the inner portion of the plug 893 that is engaged with the second post 892 is a cavity into which the second post 892 is inserted (also non-circular to prevent rotation of the plug 893), and the portion that is engaged with the tapered ramp 831 of the fluid passage 83 is a tapered ramp with a concave lower portion. Thus, when the first cylinder 891 is forcibly pressed down thereon, the first cylinder 891 moves downward, and the tapered slope of the plug 893 comes into seamless contact with the tapered slope 831 of the liquid passage 83, thereby sealing it. The plug 893 is made of a material that is much lighter than water and can be air inside so that when the first cylinder 891 is released, the plug 893 will float and open the passageway. The lower portion of the plug 893 may be of various shapes to ensure that the plug 893 floats when there is no pressure and there is not much liquid in the second chamber 82. The fluid passage 83 may take other shapes and the corresponding sealing surface of the plug 893 may be adapted to fit therein. The plug 893 cannot rotate based on the second cylinder 892, but can move up and down.

In this embodiment, the outer cap 86 may be a conventional screw cap without a drinking hole, and the screw cap is used to be connected with the second cavity 82 of the cup body in a sealing manner, and the outer cap 86 is screwed to close the inner cap, so that even if warm water flows out from the first outlet hole 851, the warm water is only in the space between the outer cap 86 and the inner cap 85, and cannot overflow.

Preferably, the first outlet hole 851 of the inner cover 85 or the edge of the inner cover portion near the outlet hole 851 protrudes from the inner cover 85, and is higher than the opening of the second cavity 82 (for example, about 1 cm higher), as long as the rotary seal of the outer cover 86 is not affected, and the protruding first outlet hole 851 can prevent the nose of the user from touching the opening of the second cavity 82 when drinking warm water. The inner cap portion of the first outlet hole 851 has a semi-open cavity, i.e., the outlet hole is narrowed toward the center of the cup body, so that warm water flows into the cavity first when drinking warm water obliquely, so that the hot water of the second cavity continuously flows into the first cavity from the liquid passage, thereby partially achieving the effect of mixing the hot water and the warm water. The other part of the outer periphery of the inner lid 85 is not protruded but is lower than the opening part of the second cavity 82 by about one centimeter. Thus, if the user wants to drink warm water, the warm water in the first chamber 81 can be drunk by unscrewing the outer cover 86 from the protruding first outlet hole 851, as shown in FIG. 9; if the user wants to drink hot water, the user unscrews the cover 86 to drink the hot water in the second cavity directly from the opening of the second cavity 82 (the portion corresponding to 180 degrees of the first outlet hole 851), as shown in fig. 10.

The outer cover can be only provided with a hot water outlet or a warm water outlet, so that water with one temperature can be directly drunk without unscrewing the outer cover. When needing to drink water with another temperature, the user can drink the water directly by unscrewing the outer cover.

According to the double-cavity vacuum cup, the two cavities are arranged, the second cavity for releasing heat water has a heat preservation function, and the first cavity is free from or provided with a small amount of phase change energy storage material at the bottom; when liquid with proper temperature needs to be drunk, high-temperature liquid can flow into the first cavity from the second cavity through the liquid channel, and can be drunk after being radiated by the first cavity or being rapidly radiated by the phase change energy storage material at the bottom of the first cavity and being radiated and cooled in a short time, so that the circulation is carried out, and a user can continuously drink the liquid with proper temperature; the two cavities are insulated, so that the heat dissipation of high-temperature liquid can be effectively prevented, the long-acting heat preservation of the liquid in the vacuum cup is ensured, and the drinking time of the liquid in the whole vacuum cup is prolonged.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be construed as the protection scope of the present invention.
