Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat-preserving water cups, in particular to a vacuum heat-preserving water cup with two heat-preserving modes. Background Technique
[0002] In order to more comprehensively and conveniently adapt to the usage scenarios of heat-preserving water cups by people; for example: making coffee, tea, etc., people need boiling water, but the suitable temperature for the oral cavity is 35°C - 50°C. Therefore, when coffee or tea is brewed, we hope the temperature can quickly drop to the suitable temperature for the oral cavity; after the water temperature drops to the suitable temperature for the oral cavity, we hope the water cup can restore its heat-preserving function so as to maintain within this suitable temperature range for a long time, especially in winter. For people who like to drink cold drinks, they also have the same need. They can freely switch the heat-preserving mode of the heat-preserving cup so as to enjoy the cold drinks they have prepared earlier for a longer time. Therefore, people more hope that the heat-preserving mode of the water cup can be dynamically adjusted according to their own needs to meet their requirements for water temperature.
[0003] The heat-preserving cups on the market all have only one heat-preserving mode, and usually achieve the heat-preserving effect through the form of vacuum pumping, but they do not have the function of freely switching the heat-preserving mode. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a vacuum heat-preserving water cup with a freely switchable heat-preserving mode.
[0005] To solve the above problems, the technical solution of the utility model is: a vacuum heat-preserving water cup with two heat-preserving modes, including a water cup outer shell and a vacuum inner cavity. An inner container is connected and arranged inside the water cup outer shell. The vacuum inner cavity is located between the water cup outer shell and the inner container. A filling base is arranged at the bottom of the water cup outer shell. Filling materials and isolation materials are arranged inside the filling base. A heat pipe is arranged inside the vacuum inner cavity.
[0006] Further, the filling materials are selected as pure iron powder of % mesh, silicon carbide of % mesh, and graphite powder of % mesh.
[0007] Further, the isolation material is selected as ceramic fiber.
[0008] Further, a cup cover is connected to the top of the water cup outer shell by a thread.
[0009] The advantages of the present utility model compared with the existing technology are as follows: Between the inner liner and the outer shell of the vacuum heat-insulating cup of the present utility model, a heat-dissipating area is isolated by a material with high temperature resistance and low heat conduction coefficient. When the heat-insulating cup works in the heat-preserving temperature mode, this area is in a vacuum state, so as to keep the water temperature from losing heat. When the heat-insulating cup works in the heat-dissipating temperature mode, this area is filled with a material with high heat conduction coefficient and high heat radiation efficiency. Coupled with the heat pipes arranged on the inner wall of the outer shell, the temperature of the hot water contained in the inner liner can be quickly transferred to the outer shell for heat dissipation through the filling material. The heat radiation effect of the filling material will also transfer the heat in the form of radiation, and the high heat conduction effect of the heat pipes will further transfer the heat. The combined action of the three paths can quickly reduce the temperature of the water. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will further illustrate the specific embodiments of the present utility model with reference to the attached drawings. Among them, the same components are denoted by the same reference numerals.
[0015] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
[0016] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the attached drawings in the embodiments of the present utility model.
[0017] Such as Figures 1 to 3As shown in the figure, there is a vacuum insulated water cup with two heat preservation modes, including a water cup outer shell 1 and a vacuum inner cavity 3. An inner container 2 is connected inside the water cup outer shell 1. The vacuum inner cavity 3 is located between the water cup outer shell 1 and the inner container 2. A filling base 4 is provided at the bottom of the water cup outer shell 1. A filling material 5 and an insulating material 6 are provided inside the filling base 4. A heat pipe 7 is provided inside the vacuum inner cavity 3. The heat pipe 7 needs to be specially customized. Originally, it was a bending process in the post-processing process. It needs to be bent and formed in advance after cutting the pipe. Because if the heat pipe is bent in the later stage, the outer wall at the bending part will become thinner, and it is very easy to explode and leak liquid during the processing of the vacuum cup - high-temperature vacuum pumping. When the thermos cup works in the heat dissipation temperature mode, this area is filled with materials with high thermal conductivity and high heat radiation efficiency. Coupled with the heat pipe 7 provided on the inner wall of the outer shell, the temperature of the hot water contained in the inner container 2 can be quickly transferred to the outer shell through the filling material 5 for heat dissipation. The heat radiation effect of the filling material 5 will also transfer the heat in the form of radiation. The high heat conduction effect of the heat pipe will further transfer the heat. The three paths work together to quickly reduce the temperature of the water.
[0018] The filling material 5 is selected as 42% of 40-mesh pure iron powder, 34% of 80-mesh silicon carbide, and 24% of 320-mesh graphite powder. Such a filling material has excellent performance in terms of fluidity, thermal conductivity, heat radiation efficiency, overall total amount, etc.
[0019] The insulating material 6 is selected as ceramic fiber. It has a low heat conduction coefficient and is heat-resistant. At 600 °C, its physical properties are stable and it hardly deforms.
[0020] A cup cover 10 is connected to the top of the water cup outer shell 1 by screw threads.
[0021] Working principle: Through the three ways of heat transfer: heat convection, heat conduction and heat radiation, an insulating heat dissipation area is separated between the inner container 2 and the water cup outer shell 1 of the vacuum thermos cup with materials that are heat-resistant and have a low heat conduction coefficient. When the thermos cup works in the heat preservation temperature mode, this area is in a vacuum state, so as to keep the water temperature from losing heat. When the thermos cup works in the heat dissipation temperature mode, this area is filled with materials with high thermal conductivity and high heat radiation efficiency. Coupled with the heat pipe provided on the inner wall of the outer shell, the temperature of the hot water contained in the inner container can be quickly transferred to the outer shell through the filling material 5 for heat dissipation. The heat radiation effect of the filling material 5 will also transfer the heat in the form of radiation. The high heat conduction effect of the heat pipe will further transfer the heat. The three paths work together to quickly reduce the temperature of the water.
[0022] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the purpose of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
