Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water cups, in particular to a double-cavity vacuum cup convenient to drink. BACKGROUND

[0002] The evaluation of the quality of vacuum cup products mainly compares the length of the heat preservation time. However, better heat preservation performance makes the tea in the vacuum cup always at a relatively high temperature, which is not directly drinkable at the temperature suitable for the oral cavity. The problem of traditional vacuum cups is not only that the heat preservation time is not enough, but also that the tea cannot be directly drunk when needed, which even has the risk of scalding.

There is a temperature difference between the first water storage cavity and the second water storage cavity.

The pressure in the first water storage cavity is released to the second water storage cavity, and the pressure can cause hot water to splash at the moment of opening the cover to drink water, which has the risk of scalding. Therefore, the prior art still needs to be improved and developed. SUMMARY

DETAILED DESCRIPTION

[0024] The technical solutions of the present application will be described below in combination with the drawings and embodiments.

[0025] For example, Figures 1-5As shown, the double-cavity thermos cup for convenient drinking provided by the present application comprises a first cup body 1 and a second cup body 2. The first cup body 1 forms a first cavity 12 with a first opening 11, and has a heat-insulating layer. The second cup body 2 forms a second cavity 22 with a second opening 21. The bottom of the second cup body 2 is provided with a heat-insulating base 3, which is arranged on the first opening 11, so that the first cavity 12 and the second cavity 22 are arranged adjacently in an up-down manner. The heat-insulating base 3 is provided with a cut-off piece 43 and a water-permeable structure. The cut-off piece 43 is movably arranged in the first cavity 12 and always tends to close the water-permeable structure, so that the first cavity 12 and the second cavity 22 are not in communication. The thermos cup further comprises a trigger piece 23, which can drive the cut-off piece 43 to move away from the water-permeable structure. When the thermos cup is inverted or inclined, the water in the first cavity 12 can enter the second cavity 22 through the water-permeable structure to be cooled.

[0026] It can be understood that the first cup body 1 has a heat-insulating layer and forms the first cavity 12 for water heat preservation. The specific structure of the first cup body 1 and the heat-insulating layer is the prior art, which will not be described here. The second cup body 2 does not have a heat-insulating structure but forms the second cavity 22 for storing water and providing a heat dissipation effect, so that the water in the second cavity 22 can be cooled to a suitable drinking temperature, and the user can drink water at any time through the second opening 21.

[0027] Further, the heat-insulating base 3 covers the lower end of the second cup body 2 to form the second cavity 22. The second cup body 2 and the first cup body 1 can be provided with threads, so that the lower end of the second cup body 2 is inserted into the first opening 11, and the heat-insulating base 3 is arranged to seal the first opening 11. In particular, the heat-insulating base 3 separates the adjacent first cavity 12 and the second cavity 22. The heat-insulating base 3 has heat-insulating properties and cooperates with the first cup body 1 to serve as a heat-insulating structure of the first cavity 22.

[0028] The thermos cup is generally in a normal upright state, such as being placed on a table or being held in hand. In this case, the second cavity 22 is above the first cavity 12, and the water can flow from the second cavity 22 to the first cavity 12 under the action of gravity. When the thermos cup is inverted, the first cavity 12 is above the second cavity 22, and the water can flow from the first cavity 12 to the second cavity.

[0029] Preferably, the heat-insulating base 3 is provided with the water-permeable structure and the cut-off piece 43. The cut-off piece 43 always tends to the water-permeable structure on the heat-insulating base 3 in the normal state, so that the water-permeable structure is always closed. In any state of the thermos cup, the first cavity 12 and the second cavity 22 are not in communication, and the water in the first cup body 1 and the second cup body 2 cannot flow in both directions. In short, no matter whether the thermos cup is in a normal upright state, an inverted state or a side-inclined state, the water in the second cavity 22 will not flow back to the first cavity 12.

[0030] Further, since the second cup body 2 does not have heat preservation, the water in the second cavity 22 will gradually cool down over time, and the pressure in the second cavity 22 will be less than that in the first cavity 12. The normally closed water permeable structure prevents the pressure in the first cavity 12 from being released to the second cavity 22, so the pressure in the second cavity 22 is closer to the external atmospheric pressure. When drinking water from the second opening 21, there will be no hot water splashing, and the use is safer.

[0031] Further, the cutoff piece 43 is in the first cavity 12, and the internal pressure of the first cavity 12 can make the cutoff piece 43 more tightly and firmly close the water permeable structure.

[0032] The second cup body 2 is provided with a trigger 23, and pressing the trigger 23 can drive the cutoff piece 43 to open the water permeable structure. At this time, the first cavity 12 and the second cavity 22 are in communication, and the hot water in the first cavity 12 can flow into the second cavity 22. Releasing the trigger 23 resets the cutoff piece 43, and the water permeable structure returns to the normally closed state. The first cavity 12 and the second cavity 22 are not in communication, and the vacuum cup can be placed or carried in any state, making the use more convenient.

[0033] It can be understood that the volume of the second cavity 22 should be more than 40ml, which can meet the user's single drinking water demand. The volume of the first cavity 12 should be much larger than that of the second cavity 22, and the volume ratio of the two should be more than 3 times, which is best to meet the user's carrying capacity when going out, so as to meet the user's multiple drinking water demand.

[0034] The heat insulation base 3 is provided with a water permeable plate 41, and the water permeable structure is arranged on the water permeable plate 41. The second cavity 22 is provided with a moving piece 42 matched with the cutoff piece 43. The water permeable plate 41 is provided with a connecting rod 44, and the two ends of the connecting rod 44 are connected with the moving piece 42 and the cutoff piece 43 respectively. The moving piece 42 and the water permeable plate 41 are provided with a spring 45 abutting with each other, and the spring 45 drives the moving piece 42 to drive the cutoff piece 43 to always tend to the water permeable plate 41 to close the water permeable structure.

[0035] The moving piece 42 and the cutoff piece 43 are arranged in the first cavity 12 and the second cavity 22 respectively on both sides of the water permeable plate 41, and the cutoff piece 43 and the moving piece 42 are connected by the connecting rod 44 and realize synchronous action. Further, the spring 45 is arranged between the moving piece 42 and the water permeable plate 41, and the spring 45 can be used to drive the moving piece 42 to move away from the water permeable plate 41, and correspondingly the cutoff piece 43 tends to the water permeable plate 41 to close the water permeable structure. Of course, the trigger 23 can drive the moving piece 42 to overcome the force of the spring 45, so that the cutoff piece 43 moves away from the water permeable plate 41 to open the water permeable structure.

[0036] It can be understood that the heat insulation base 3 is arranged between the first cavity 12 and the second cavity 22, and the heat insulation base 3 is arranged in the first opening 11, so that the heat insulation base 3 can meet the sealing and blocking function design through the wall feature and the cooperation of the stop piece 43.

[0037] Specifically, the water permeable plate 41 and the stop piece 43 adopt a face-to-face cooperation mode, so that the water permeable plate 41 also has a wall feature, and thus the water permeable plate 41 can be directly arranged on the heat insulation base 3 to form an integrated structure. Since the second cavity 22 and the first cavity 12 are arranged adjacent to each other in an up-down manner, the stop piece 43 can be moved up and down to cooperate with the water permeable plate 41 to realize the on-off control of the water permeable structure.

[0038] Preferably, the stop piece 43 is arranged in the first cavity 12. Due to the heat preservation of the first cup body 1, the water temperature in the first cavity 12 is very high and the pressure is large. The second cup body 2 does not have heat preservation, and the water in the second cavity 22 gradually cools down over time. The pressure of the second cavity 22 is smaller than that of the first cavity 12. The pressure in the first cavity 12 can make the stop piece 43 more closely fit the water permeable plate 41, so that the sealing property of the stop valve 4 is enhanced.

[0039] The water permeable plate 41 is provided with a plurality of guide holes 411, a connecting rod 44 is arranged in the guide hole 411, and a spring 45 is sleeved on one of the connecting rods 44. It can be understood that a plurality of connecting rods 44 can be arranged between the action piece 42 and the stop piece 43, and the spring 45 can be sleeved on one of the connecting rods 44. In the embodiment, the number of connecting rods 44 is three, which corresponds to the arrangement of three guide holes 411 on the water permeable plate 41. The three guide holes 411 are distributed in a triangular positioning mode on the water permeable plate 41, so as to ensure the connection strength and action synchronization between the stop piece 43 and the water permeable plate 41.

[0040] The edge of the stop piece 43 is provided with a sealing ring 431. When the stop piece 43 approaches the water permeable plate 41, the sealing ring 431 is fitted to the water permeable plate 41 and surrounds the water permeable structure to make it closed. The action piece 42 and the stop piece 43 are connected through the connecting rod 44. The connecting rod 44 can slide along the guide hole 411, so that the action piece 42 and the stop piece 43 approach or move away from the water permeable plate 41. The action piece 42, the connecting rod 44 and the stop piece 43 are integrally linked, so these three components need to be made of rigid material to avoid deformation.

[0041] The stop piece 43 and the water permeable plate 41 form a face-to-face cooperation, and the cooperation between the rigid materials has a sealing problem. Therefore, the sealing ring 431 needs to be arranged on the edge of the stop piece 43. The stop piece 43 approaches and is close to the water permeable plate 41. The sealing ring 431 surrounds the water permeable structure and the guide hole 411 to realize the on-off control of the two sides of the water permeable plate 41.

[0042] It can be understood that the upper end of the cup is usually provided with a cup cover, which occupies the space of the upper end of the second cup body 2, so that the trigger 23 needs to be arranged on the side wall of the second cup body 2, and the action of the trigger 23 is generally transverse movement. If the stop piece 43 can move up and down to cooperate with the water permeable plate 41 to realize the on-off control of the water permeable structure, a change structure needs to be arranged between the trigger 23 and the action piece 42 for transmission, so that the structure becomes more complex.

[0043] The application also comprises a valve body 46, which is protrudingly arranged on the heat insulation base 3, one side wall of the valve body 46 is formed by the water permeable plate 41, and the trigger 23 is arranged on the side wall of the second cup body 2; the valve body 46, the water permeable plate 41, the action piece 42, the stop piece 43 and the spring 45 form a normally closed stop valve 4. The valve body 46 is used to build a space to install the functional components of the stop valve 4, and to separate the water permeable plate 41 from the heat insulation base 3, so as to avoid that the structure of the heat insulation base 3 is too complex. The heat insulation base 3 is provided with a drain port 461, which is communicated with the inner cavity of the valve body 46 and the first cavity 12, and the stop piece 43 is movably arranged in the inner cavity of the valve body 46.

[0044] Especially, the valve body 46 is protrudingly arranged on the heat insulation base 3, and the valve body 46 makes the water permeable plate 41 vertically arranged on the heat insulation base 3. The valve body 46 is eccentrically arranged on the heat insulation base 3, so that the water permeable plate 41 is close to the side wall of the second cup body 2, and the trigger 23 is arranged on the side wall of the second cup body 2 and is arranged in pair with the action piece 42. The action piece 42 and the stop piece 43 move along the transverse direction relative to the water permeable plate 41, so that the movement direction of the trigger 23 and the action piece 42 is the same, and the action piece 2 can be directly driven by pressing the trigger 23 on the second cup body 2, so as to realize the on-off control of the stop valve 4. Especially, the valve body 46 is protrudingly arranged, so that the water permeable plate 41 can be closer to the side wall of the second cup body 2, which is convenient for the trigger 23 to control the stop valve 4 and shortens the trigger action stroke of the trigger 23.

[0045] The water-permeable structure comprises water-permeable openings 412, and the water-permeable plate 41 is provided with at least two water-permeable openings 412, and the diameter of the water-permeable opening 412 is greater than 2 mm. The water-permeable opening 412, the inner cavity of the valve body 46 and the water outlet 461 constitute a water path for connecting the first cavity 12 and the second cavity 22, and the cutoff piece 43 is arranged in the inner cavity of the valve body 46 and cooperates with the water-permeable plate 41 to control the opening and closing of the water-permeable opening 412. As described above, when the heat preservation cup is inverted, the water in the first cavity 12 can flow into the second cavity 22. Due to the limited area of the water-permeable plate 41 and the limited diameter of the water-permeable opening 412, if there is only one water-permeable opening 412 on the water-permeable plate 41, the water tension will form a pressure barrier in the hole, making it difficult for water to pass through. In the embodiment, the water-permeable plate 41 is provided with at least two water-permeable openings 412, and a plurality of passages are arranged between the inner cavity of the valve body 46 and the second cavity 22, which can not only expand the flow of the water-permeable structure, but also avoid water path blockage through pressure difference fluctuation between the plurality of water-permeable openings 412.

[0046] Briefly, since the first cavity 12 and the second cavity 22 are both arranged in a sealed manner, the water in the first cavity 12 needs to flow to the second cavity 22, and the gas in the second cavity 22 needs to flow to the first cavity 12, forming water-gas exchange, and the water-permeable plate 41 has a plurality of water-permeable openings 412, which can make water and gas pass through the water-permeable openings 412 on the water-permeable plate 41 at the same time (in opposite directions), preventing the formation of a water seal (barrier) at the water-permeable plate 41.

[0047] Further, the shape of the water-permeable opening 412 does not need to be specially designed, and generally the water-permeable opening 412 can be circular, square or strip-shaped, but the water-permeable opening 412 of any shape cannot be too small, that is, the diameter of the circular water-permeable opening 412 needs to be greater than 2 mm, and the width of the square water-permeable opening 412 needs to be greater than 2 mm.

[0048] Preferably, the diameter of the water-permeable opening 412 is 3 mm, and the larger the diameter of the water-permeable opening 412, the more difficult it is for water to form a water seal (barrier) at the water-permeable opening 412.

[0049] Further, the water-permeable structure further comprises a gas return groove 413, and the water-permeable plate 41 is provided with at least one gas return groove 413, and the gas return groove 413 is arranged below the water-permeable opening 412; the gas return groove 413 is a long strip-shaped opening, and the width of the gas return groove 413 is greater than 1 mm. The water-permeable plate 41 is vertically arranged, the length direction of the gas return groove 413 is parallel to the vertical direction, and the gas return groove 413 is arranged in correspondence with the water-permeable opening 412 in the upward and downward directions.

[0050] When the cup is tilted to be inverted, the water in the first cavity 12 enters the inner cavity of the valve body 46, and the water level in the valve body 46 changes. Since the air return groove 413 is above the water permeable port 412, the water preferentially submerges the water permeable port 412. Of course, the water level fluctuation in the valve body 46 will also partially or completely immerse the air return groove 413, but due to the height difference between the air return groove 413 and the water permeable port 412, the water in the first cavity 12 preferentially enters the second cavity 22 through the water permeable port 412, and the air pressure in the second cavity 22 can enter the first cavity 12 through the air return groove 413, thereby completing the water-air exchange. If the air return groove 413 is also completely submerged, the cup can be tilted appropriately to reduce the water seal pressure at the air return groove 413 (reduced immersion depth), so that the air pressure in the second cavity 22 can break through the water seal (barrier) at the air return groove 413.

[0051] The side wall of the second cup body 2 is provided with an encapsulation groove 231 and a plastic encapsulation piece 232, and the encapsulation groove 231 is provided with a switch hole 233 penetrating the second cavity 22. The trigger piece 23 is provided with a disc-shaped cover 234, and the plastic encapsulation piece 232 fixes the disc-shaped cover 234 in the encapsulation groove 231, and the trigger piece 23 is movably arranged in the switch hole 233, and the inner end of the trigger piece 23 is paired with the action piece 42. The encapsulation groove 231 is provided with a clamping groove, and the edge of the disc-shaped cover 234 can be clamped in the clamping groove of the encapsulation groove 231 through the plastic encapsulation piece 232 to be fixed, so that the trigger piece 23 is movably arranged in the switch hole 233, and the disc-shaped cover 234 seals the switch hole 233.

[0052] As shown in Figure 5 The heat insulation base 3 is provided with a base sleeve 31, and the base sleeve 31 is provided with a channel port 32 paired with the drain port 461, and the channel port 32 is provided with a filter piece 33.
