Description

Technical Field

[0001] The present invention relates to the technical field of thermos cups, and in particular to a thermos cup with double drinking spouts. Background Art

[0002] A thermos cup is a cup that uses a vacuum layer between the inner liner and the cup body to achieve thermal insulation, slowing the dissipation of liquids such as water, thereby achieving the purpose of heat preservation. Although existing thermos cups can meet the function of keeping liquids warm, the poor insulation effect means that the water temperature cannot be quickly cooled, making it difficult to drink comfortably.

[0003] The structure of the existing thermos cup that can be drunk quickly is usually equipped with a water diversion chamber on the outside of the inner liner. The space in the water diversion chamber is a fast cooling space, which drains the high-temperature water in the inner liner into the water diversion chamber. The water diversion chamber has the effect of fast cooling, which is convenient for users to drink in time and quench their thirst. However, this type of thermos cup still has shortcomings: 1. The thermos cup can only be used by oneself and is difficult to share. That is, the thermos cup is usually a personal item. In order to avoid the spread of disease, it can only be used by individuals for fast cooling. 2. When the inner liner drains water into the water diversion chamber, the water drainage speed is too slow, and the operation is inconvenient. 3. The inner liner does not have the effect of slow cooling. That is, when the water in the inner liner needs to be slowly cooled, the usual way of handling it is to unscrew the cover of the inner liner. The cover is located at the top of the inner liner. After unscrewing, the diameter of the mouth of the inner liner is large, which not only dissipates heat quickly, but also makes it easy for foreign objects to fall into the inner liner and pollute the water.

[0004] To this end, the present invention provides a thermos cup with double drinking spouts. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-3A double drinking spout thermos cup, comprising an inner liner 1 and a cup lid 2. The inner liner is made of stainless steel and has a hollow insulation structure. The outer surface of the inner liner 1 is covered with an insulation shell 3, which is an insulating shell made of insulation material. It also includes a sub-cup body 5. The sub-cup body 5 is smaller in size. A touch valve body 4 is provided at the bottom of the inner liner 1. One end of the sub-cup body 5 is connected to a switching valve head 6 with the function of opening and closing the sub-cup body 5. One end of the sub-cup body 5 is also rotatably connected to the switching valve head 6. When the switching valve head 6 rotates relative to the sub-cup body 5, the sub-cup body 5 is in two states: connected to the outside world and opened and closed. The sub-cup body 5 is connected to the inner cavity of the inner tank 1 through the adapter valve head 6 and the touch valve body 4. That is to say, the touch valve body 4 is connected to the sub-cup body 5 and the inner cavity of the inner tank 1 only when it is plugged into the adapter valve head 6. The touch valve body 4 adopts a common plug-in connecting valve body. In summary, in the above technical solution, when the sub-cup body 5 is connected to the inner tank 1, the hot water in the inner tank 1 enters the sub-cup body 5 through the touch valve body 4 and the adapter valve head 6 in sequence. After the sub-cup body 5 is filled with water, the sub-cup body 5 is screwed to be in a closed state. At this time, the sub-cup body 5 can be cooled quickly alone. When it is used, the connection The transfer valve head 6 of the sub-cup body 5 can be manually pulled out to drink through the transfer valve head 6, wherein the number of the sub-cup bodies 5 can be multiple, that is, multiple sub-cup bodies 5 can be installed on an inner tank 1, and each sub-cup body 5 corresponds to a touch valve body 4 and a transfer valve head 6, which is convenient for sharing drinking water or beverages with others; the bottom of the insulation shell 3 is connected to a base 102 located below the sub-cup body 5 through a support column, and a guide seat 8 is provided on the base 102, and a transmission shaft 9 is rotatably connected to the guide seat 8. One end of the transmission shaft 9 is fixedly connected to an eccentric disc 91, and the transfer valve head 6 A groove 64 that cooperates with the eccentric disc 91 is provided on one side of the eccentric disc 91. Manually rotating the transmission shaft 9 can drive the eccentric disc 91 to rotate. When the switching valve head 6 is plugged into the touch valve body 4, the groove 64 on it is buckled on the outside of the eccentric disc 91, and then the transmission shaft 9 is manually rotated. The center disc 91 will push the switching valve head 6 to move upward to complete the plugging with the touch valve body 4. A limiting groove can be provided on the guide seat 8 to guide the switching valve head 6, so that the switching valve head 6 moves up and down along the limiting groove, further improving the convenience of the switching valve head 6 in docking with the touch valve body 4.

[0036] Example 2

[0037] See also Figure 3-5In embodiment 1, it is recorded that after the inner tank 1 is connected to the sub-cup 5 through the adapter valve head 6 and the touch valve body 4, the water in the inner tank 1 is transferred to the sub-cup 5. However, there is a problem that the water enters the sub-cup 5 slowly due to the presence of air in the sub-cup 5. In view of this, the difference between this embodiment and embodiment 1 is that a sealing hole 41 is provided at the bottom of the touch valve body 4, one end of the adapter valve head 6 is fixedly connected to a cannula 61 matched with the sealing hole 41, and a connecting hole 41 is provided at the top of the touch valve body 4. The water inlet 42 and the respiratory duct 43 of the sealed jack 41 are fixedly connected to the top of the valve body 4 with a breathing tube 44 connected to the respiratory duct 43. The top of the breathing tube 44 extends to the top of the inner tank 1. The adapter valve head 6 is provided with two channels 62 respectively opposite to the water inlet 42 and the respiratory duct 43. One end of the sub-cup body 5 is provided with a water port 51 and a vent tube 52 extending to the sub-cup body 5. The water port 51 and the vent tube 52 are respectively matched with the two channels 62. In use, that is to say, the breathing tube 44, a channel 62, and the vent tube 52 form a breathing passage, and the hollow area at the top of the inner liner 1 is connected with the air area in the sub-cup body 5 through the breathing tube 44, a channel, the vent tube 52, and the sub-cup body 5. Therefore, when the water in the inner liner 1 enters the sub-cup body 5 through the water inlet 42, another channel and the water port 51, the air in the sub-cup body 5 can quickly enter the inner liner 1 through the breathing passage, so that the water in the inner liner 1 can quickly enter the sub-cup body 5, wherein one end of the sub-cup body 5 is fixedly connected with a docking tube 53, and the water port 51 and the mouth of the vent tube 52 are located on the outer peripheral wall of the docking tube 53. The other end of the switching valve head 6 is provided with a positioning hole 63 that is rotatably sealed with the docking tube 53. The positioning hole 63 is connected with the channel 62. When the docking tube 53 is rotated until the water port 51 and the mouth of the vent tube 52 on it are opposite to the two channels 62, the sub-cup body 5 is in an open state, otherwise the sub-cup body 5 is in a closed state.

[0038] Example 3

[0039] See also Figure 3 and Figure 4 The difference from Example 2 is that the sub-cup body 5 is horizontally arranged, and the ventilation tube 52 is located at one end inside the sub-cup body 5 and extends to the other end and is located at the top. This arrangement can greatly reduce the space occupied by the entire thermos cup, that is, it can reduce the overall height of the thermos cup. One end of the insertion tube 61 is fixedly connected to a suction nozzle 611 corresponding to the ventilation tube 52, and a makeshift docking groove 411 matching the suction nozzle 611 is opened in the sealing socket 41. The suction nozzle 611 corresponds to the breathing tube 44 and the ventilation tube 52. Since one end of the ventilation tube 52 extends to the other end inside the sub-cup body 5, the user can directly drink the water or beverage in the sub-cup body 5 through the suction nozzle 611, which is more convenient to drink.

[0040] Example 4

[0041] See also Figure 4 , and the difference from Example 2 is that the middle part of the touch valve body 4 is circumferentially slidably connected to a valve shaft 45, one end of the valve shaft 45 is fixedly connected to a valve plate 451 in the inner tank 1 and opposite to the water inlet 42, and the other end of the valve shaft 45 is fixedly connected to a limit push plate 452. A clearance groove 412 is provided at the bottom of the sealing socket 41, and the valve shaft 45 is sleeved with a return spring 46 located between the clearance groove 412 and the limit push plate 452. After the cannula 61 is inserted into the sealing socket 41, it pushes the limit push plate Plate 452, at this time the return spring 46 will be compressed, the valve plate 451 will be away from the water inlet 42, and the water inlet 42 will be in an open state. When the sub-cup body 5 is removed, the return spring 46 will be reset. At this time, the valve plate 451 will block the water inlet 42. At this time, the top space of the inner cavity of the inner liner 1 is connected to the outside world through the breathing tube 44, and the high-temperature water vapor at the top of the inner liner 1 will be slowly discharged from the bottom. This valve control structure is convenient for slowly cooling the high-temperature water in the inner liner 1, and this cooling method is more hygienic.

[0042] Example 5

[0043] See also Figure 1 and Figure 2 The difference from Example 1 is that a bottle mouth 11 is provided on the top of the inner liner 1, and the cup cover 2 is screwed together with the bottle mouth 11. The outer part of the cup cover 2 is rotatably connected to a connecting rod 7, and one end of the connecting rod 7 is fixedly connected to a rubber seal 101. The top of the inner liner 1 is fixedly connected to an auxiliary drinking port 12 located on one side of the bottle mouth 11. The auxiliary drinking port 12 and the rubber seal 101 are used together. The auxiliary drinking port 12 and the bottle mouth 11 belong to a double drinking port structure. The bottle mouth 11 is convenient for drinking in large sips, and the auxiliary drinking port 12 is convenient for drinking in small sips. The rubber seal 101 plays the role of sealing the bottle mouth 11.

[0044] Working principle: During use, when it is necessary to drink low-temperature water alone, rotate the sub-cup body 5 so that the sub-cup body 5 is connected to the inner cavity of the inner liner 1 through the adapter valve head 6 and the touch valve body 4. Under the ventilation action of the respiratory tract 43, one channel 62 and the vent pipe 52, the water in the inner liner 1 quickly enters the sub-cup body 5 through the water inlet 42, another channel 62 and the vent pipe 52 in sequence and fills it. Then control the sub-cup body 5 to continue rotating so that the sub-cup body 5 and the inner liner 1 are blocked. The sub-cup body 5 is made of a material with good thermal conductivity, which facilitates rapid heat dissipation. When drinking, manually control the transmission shaft 9 to rotate, and the eccentric disc 91 pushes the groove 64 downward to disengage the touch valve body 4 and the adapter valve head 6. At this time, the water in the sub-cup body 5 can be drunk through the suction nozzle 611.
