Description

Technical Field

[0001] The utility model relates to the technical field of travel cups, in particular to a vacuum double-layer travel cup. Background Art

[0002] A water cup is a commonly used water container with a lid on the top and a tight seal. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside it to achieve the purpose of heat preservation. This feature makes thermos cups popular among consumers, especially for the elderly and children who have poor gastrointestinal function and should not drink too much cold water. Thermos cups are a must-have item for winter travel and tourism.

[0003] Among them, travel mugs are common and frequently used cups in life. When in use, they need to be used for a long time during travel, so the heat preservation of travel mugs is very important. Existing travel mugs are mostly single-layer structures when in use, and have great defects in heat preservation and thermal insulation. They cannot meet the user's demand for water temperature during travel, which further affects the user's actual use. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a vacuum double-layer travel cup.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A vacuum double-layer travel cup comprises an outer tube, an inner tube is arranged on the inner side of the outer tube, an insulating pad is fixedly connected to one end of the inner tube close to the outer tube, an interlayer tube is fixedly connected to the inner wall of the outer tube, a plurality of circumferentially arranged diverging plates are fixedly connected to the inner side wall of the interlayer tube, the diverging plates are fitted with the inner tube, a stabilizing mechanism for keeping the cup stable is arranged at one end of the outer tube, a bottle cap is arranged at the other end of the outer tube, a stop block is fixedly connected to the inner top of the bottle cap, a sealing ring is sleeved on the side wall of the stop block, and a buffer mechanism for buffering the internal pressure of the cup is arranged at the side of the sealing ring close to the inner tube.

[0007] Preferably, the stabilizing mechanism comprises a contact pad arranged on one side of the outer tube, a side of the outer tube close to the contact pad is provided with a plurality of mounting grooves, and a side of the contact pad close to the mounting groove is fixedly connected with a plurality of mounting rings.

[0008] Preferably, the mounting groove and the mounting ring are both distributed in an annular shape, and the mounting groove is filled with glue.

[0009] Preferably, the buffer mechanism comprises a plurality of circumferentially arranged buffer tubes fixedly connected to a side of the bottle cap close to the inner tube, and a buffer rod is slidably connected to one end of the buffer tube close to the inner tube.

[0010] Preferably, a buffer spring is fixedly connected inside the buffer tube, and one end of the buffer spring away from the buffer tube is fixedly connected to the buffer rod.

[0011] Preferably, a sealing groove is provided on one side of the bottle cap close to the outer tube, a fitting ring is fixedly connected in the sealing groove, and the fitting ring fits with the outer tube.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with structures such as an inner tube, an outer tube, a barrier tube and a diverging plate. The barrier tube is provided between the outer tube and the inner tube to block the loss rate of the inner tube problem. At the same time, under the reverse diverging temperature effect of the diverging plate, the heat transmitted from the inner tube can be returned to the inner tube by way of radiation, thereby avoiding the excessive loss of hot water temperature and thus extending the insulation time of the travel cup.

[0014] 2. The utility model is provided with structures such as a stopper, a sealing ring, a buffer tube and a buffer rod. Through the sliding buffering of the buffer rod inside the buffer rod, the internal pressure of the travel cup can be adjusted to avoid the problem that the cup cover and the cup body are sucked together and cannot be opened due to a large temperature difference between the front and back of the water, thereby facilitating the use of the travel cup.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] Reference Figure 1-4 A vacuum double-layer travel cup comprises an outer tube 1, an inner tube 2 is arranged on the inner side of the outer tube 1, an insulating pad 5 is fixedly connected to one end of the inner tube 2 close to the outer tube 1, an interlayer tube 3 is fixedly connected to the inner wall of the outer tube 1, a plurality of circumferentially arranged diverging plates 4 are fixedly connected to the inner side wall of the interlayer tube 3, the diverging plates 4 are fitted with the inner tube 2, a stabilizing mechanism for keeping the cup stable is arranged at one end of the outer tube 1, the stabilizing mechanism comprises a contact pad 6 arranged on one side of the outer tube 1, a plurality of mounting grooves 8 are opened on one side of the outer tube 1 close to the contact pad 6, the mounting grooves 8 and the mounting rings 7 are both distributed in an annular manner, the mounting grooves 8 are filled with glue, and a plurality of mounting rings 7 are fixedly connected to one side of the contact pad 6 close to the mounting groove 8.

[0022] A bottle cap 9 is provided at the other end of the outer tube 1. A sealing groove 14 is provided on a side of the bottle cap 9 close to the outer tube 1. A fitting ring 15 is fixedly connected in the sealing groove 14. The fitting ring 15 fits the outer tube 1.

[0023] A stopper 10 is fixedly connected to the inner top of the bottle cap 9, and a sealing ring 11 is sleeved on the side wall of the stopper 10. A buffer mechanism for buffering the internal pressure of the cup is provided on the side of the sealing ring 11 close to the inner tube 2. The buffer mechanism includes a plurality of circumferentially arranged buffer tubes 12 fixedly connected to the bottle cap 9 close to the inner tube 2, a buffer spring is fixedly connected inside the buffer tube 12, an end of the buffer spring away from the buffer tube 12 is fixedly connected to a buffer rod 13, and an end of the buffer tube 12 close to the inner tube 2 is slidably connected to the buffer rod 13.

[0024] When the utility model is used, Figure 1-4As shown, when in use, the hot water in the inner tube 2 first transfers heat to the space between the inner tube 2 and the outer tube 1 through air transmission. At this time, the heat is isolated in the area between the inner tube 2 and the outer tube 1 through the insulating layer 3. At this time, the heat is reflected and diffused by multiple diffuser plates 4, and the dissipated heat can be diffused back to the tube wall of the inner tube 2. The temperature of the water in the inner tube 2 is ensured by reducing the heat loss, thereby reducing the speed of the hot water temperature loss in the travel cup, that is, improving the insulation effect of the travel cup. At the same time, when the bottle cap 9 is in use, the sealing ring 11 and the fitting ring 15 are in contact with the outer tube 1 to ensure the sealing between the bottle cap 9 and the outer tube 1. When the temperature difference in the inner tube 2 decreases relative to before after a long time, the pressure in the inner tube 2 and the outer tube 1 changes. At this time, the buffer rod 13 is active and buffered in the buffer tube 12 under the traction of the buffer spring, which is used to adjust the pressure in the inner tube 2 to avoid the phenomenon that the bottle cap 9 cannot be opened normally.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
