Fig. 1 is a schematic structural view of a cup with free temperature access according to an embodiment of the invention.
Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
The invention is described in further detail below with reference to the figures and specific examples.
Referring to fig. 1, an embodiment of the present invention provides a water cup with free temperature access, which mainly includes two parts, namely an inner container 11 and an outer shell 12, wherein the inner container 11 and the outer shell 12 are both in a cylindrical cup shape, the top is open, the bottom is closed, and the whole body around the inner container is cylindrical. The periphery of inner bag 11 is less than the periphery of shell 12, arranges inner bag 11 in the inside of shell 12, and the opening top of both adopts welding sealing to link together, forms the rim of a cup part of drinking cup, preferably, upwards extends behind the integrative welding of the opening top of inner bag 11 and shell 12 and forms an annular rim of a cup part, and the outside cover of rim of a cup part is equipped with a bowl cover 13 for solution to the holding in the inner bag 11 keeps warm or keeps cold. The connection between the rim portion and the lid 13 is a conventional design of a vacuum cup, such as a threaded screw.
The height of the inner container 11 is less than that of the shell 12, after the cup openings of the inner container and the shell are welded, a sealing space 14 is formed between the inner container 11 and the shell 12 and between the whole body and the bottom of the shell 12, the inner container 11 and the shell 12 are separated from each other by the sealing space 14, the sealing space 14 is in a vacuum or semi-vacuum state, and the temperature of the inner container 11 is prevented from being transmitted to the shell 12, so that the heat preservation effect is achieved. The low boiling point liquid 15 is filled in the sealed space 14, and the height of the low boiling point liquid 15 (the amount of the low boiling point liquid) is such that the liquid surface can not contact the inner container 11 when the cup is placed, so that the sealed space 14 separates the low boiling point liquid 15 from the inner container 11 to play a role of heat preservation when the cup is placed, and the liquid in the inner container 11 is kept warm for a long time.
Wherein, the boiling point temperature (at normal temperature and normal pressure) of the low boiling point liquid 15 should be lower than 60 degrees celsius, preferably, the boiling point temperature of the low boiling point liquid 15 is between 30 and 60 degrees celsius, such as: the specific gravity of the liquid such as perfluorohexanone, low-boiling perfluorohexanone and the like is greater than that of air after the liquid is heated and vaporized. The materials of the inner container 11 and the outer shell 12 can be selected from: such as stainless steel, aluminum, copper, etc. The bottom of the casing 12 is filled with the low boiling point liquid 15 through a liquid filling hole 16, and after the low boiling point liquid 15 is filled, the liquid filling hole 16 is not immediately sealed, but the cup is turned upside down (the cup mouth part faces downwards), so that the low boiling point liquid 15 is positioned at the cup mouth part, the low boiling point liquid 15 is gradually gasified or partially gasified by heating the cup, because the specific gravity of the gasified low boiling point liquid 15 is greater than that of the air, the air in the sealed space 14 can be lifted upwards, and after most or all of the air is discharged from the sealed space 14, the liquid filling hole 16 is sealed, so that the inside of the sealed space 14 is in a vacuum or semi-vacuum state. Therefore, the problem that the traditional vacuumizing process cannot vacuumize the sealed space 14 after liquid injection is effectively solved, and the traditional vacuumizing process can cause the sealed space 14 to form pressure difference with the external atmospheric pressure in the process of enabling the sealed space 14 to form vacuum, so that the liquid low-boiling-point liquid 15 can be extracted. And because the air pressure of the vacuum environment is low, the boiling point temperature of the low boiling point liquid 15 can be reduced, so that the low boiling point liquid is more easily extracted along with air, and the low boiling point liquid with enough quantity in the sealed space can not be left after the vacuum-pumping treatment is ensured, so that the heat preservation effect of the water cup is damaged.
The boiling temperature of the low boiling liquid 15 is best at a temperature in the preferred range of 30-60 degrees celsius. Wherein, the upper limit of the boiling point is set to be 60 ℃ because the hot drink is not suitable for direct drinking and is easy to cause esophageal injury when exceeding 60 ℃; the lower limit of the boiling point is set to 30 ℃ because the effect is not good when the temperature is lower than 30 ℃, if the temperature is lower than the body temperature and heat release is continued, the temperature is very low, the heat preservation effect is poor, and the heat preservation effect is greatly influenced by the external temperature.
As further shown in fig. 1, the bottom surface of the casing 12 is formed with one or more concave pits 17 for forming the liquid injection hole 16 and being concave toward the inside of the casing 12, and the concave pits 17 are in the shape of a truncated cone, and the inner diameter thereof is gradually reduced from the bottom to the inside of the casing 12. Preferably, a positioning tip 171 which is continuously recessed toward the inside of the housing 12 is further formed at the middle position of the truncated cone surface of the recess 17, and is in a pointed shape, and is matched with the shape of a drill rod tip of a drilling instrument, such as a drilling machine, so that the drilling position can be better positioned and the deviation can be avoided. And through setting up above-mentioned pit 17, can make the position of punching be restricted in the pit scope, can not damage the other parts of the shell bottom outside the pit, play the guard action to the drinking cup.
In addition, a bottom cover 18 is covered on the outer side of the bottom of the shell 12 for covering the bottom of the shell operated in the process of making the water cup, so as to achieve the effects of beauty and further leakage prevention.
The traditional vacuumizing mode cannot vacuumize a conventional hand warming cup or an ice compress cup after heat conducting liquid is filled in the cup, the vacuum-pumping method skillfully utilizes the principle that the gasification temperature of low-boiling-point liquid 15 is not high, and gasified gas is heavier than air to evacuate, and the specific method comprises the following steps:
firstly, a liquid injection hole 16 is formed in the bottom of a shell 12 of a water cup, and the liquid injection hole 16 can be quickly and accurately formed through a concave pit 17 which is arranged in the bottom of the shell 12 in advance;
then, a liquid injection machine is inserted into the liquid injection hole 16, the liquid injection hole 16 is utilized to inject the low-boiling-point liquid 15 into the sealed space 14 between the inner container 11 and the shell 12, the liquid level of the low-boiling-point liquid 15 injected into the sealed space 14 is controlled to be lower than the bottom surface of the inner container 11 when the water cup is placed right, namely the low-boiling-point liquid 15 is controlled not to be in contact with the inner container 11, and the inner container 11 can continuously release heat because the low-boiling-point liquid 15 is vaporized due to hot water filled after the contact so as to lose the heat preservation effect;
after the liquid injection is finished, the cup opening part of the water cup is placed downwards, and the low-boiling-point liquid 15 flows to the lower cup opening part;
then, the whole cup filled with the low boiling point liquid 15 is heated, preferably, the cup mouth part below the cup when the cup is inverted at the moment can be heated, because the low boiling point liquid is closer to the cup mouth part, the low boiling point liquid 15 is gasified and turns into gaseous low boiling point liquid after being gasified, the low boiling point liquid is preferably low boiling point liquid such as perfluorohexanone with the boiling point temperature between 30 and 60 ℃, and after being gasified, the specific gravity is greater than that of air, so that the air in the sealed space 14 can be lifted upwards and discharged out of the sealed space 14 through the liquid injection hole;
after heating for a certain period of time, the pour hole 16 is sealed by soldering, and a vacuum or semi-vacuum state is formed in the sealed space.
The heating time is related to the heating temperature, the shape design of the inner container, the material selection of the cup body and the like, specific data can be obtained by repeated tests of the designed cup body, and meanwhile, the sealed space can be ensured to reach a vacuum or semi-vacuum state.
Therefore, on one hand, the invention provides a novel water cup structure with free temperature access, which has a simple structure, but has complete functions and has the functions of heat preservation, cold insulation, hand warming and ice compress. On the other hand, the method is suitable for discharging vacuum after liquid is injected into the sealed space in the water cup with free temperature access.
In addition, because the low-boiling-point liquid is not high in gasification temperature and easy to gasify, the pressure intensity of a sealing space between the inner container and the shell of the water cup can be changed quickly by gas-liquid phase change of the low-boiling-point liquid, so that the boiling point temperature of the low-boiling-point liquid is reduced or increased, and the rapid conduction of the temperature between the inner container and the shell of the water cup is realized. After the vacuum pumping, the pressure in the sealed space is lower, and the gasification temperature of the low-boiling-point liquid is reduced, so that the gasification process is quicker than the normal pressure state when the low-boiling-point liquid contacts the high-temperature liner, and the absorbed heat is more and more quick. Meanwhile, the rapid gasification leads the sealed space to be filled with a large amount of gas, so that the pressure in the sealed space is rapidly increased, the liquefaction temperature of the heat-conducting gas after the low-boiling-point liquid is gasified is increased, the heat-conducting gas is easier to liquefy, a large amount of heat is released by liquefaction, the temperature of the shell is rapidly increased, and the effect of rapidly transmitting the heat of the liner to the shell is achieved.
Specifically, the low boiling point liquid 15 has a boiling point temperature lower than that of the normal temperature and pressure state because it is in a low pressure state (vacuum or semi-vacuum state of the sealed space), so that it is easier to gasify than that under normal pressure and the gasification process is quicker. Because the low boiling point liquid 15 can absorb a large amount of heat in the gasification process, the gasification process of the low boiling point liquid 15 is quicker, the change of the absorbed heat in the gasification process is larger, the gas after the low boiling point liquid 15 is gasified is quicker in heat conduction, and the heat conduction between the inner container and the outer shell is accelerated.
When a hot liquid (the temperature is higher than 60 ℃ or higher than the boiling point temperature of the low boiling point liquid 15 to 100 ℃) is contained in the inner container of the cup, the cup can be kept warm for a long time because the sealed space between the inner container and the shell is in a vacuum or semi-vacuum state when being placed in the forward direction.
When people want the temperature in the cup to be quickly reduced to the temperature suitable for drinking or want to warm hands by using the cup, people can shake the cup to enable the low-boiling-point liquid 15 to be in contact with the inner container 11, the inner container 11 conducts heat to the low-boiling-point liquid 15 to enable the low-boiling-point liquid 15 to be quickly gasified, the gasified heat-conducting gas fills the sealed space 14, the inner container 11 and the shell 12 conduct heat through the gas generated by gasifying the low-boiling-point liquid 15, the heat of hot liquid in the cup is conducted out, the temperature of the hot liquid is quickly reduced to the temperature suitable for drinking, meanwhile, the temperature of the shell 12 is increased, and the cup is held in hands to play a hand warming effect.
Because the pressure in the sealed space 14 is suddenly increased by the gaseous low-boiling-point liquid 15, so that the liquefaction temperature of the gasified gas of the low-boiling-point liquid 15 is increased, when the gasified gas of the low-boiling-point liquid 15 contacts the shell 12, the gaseous low-boiling-point liquid 15 exchanges heat with the shell 12, so that the temperature of the place where the gaseous low-boiling-point liquid 15 contacts the shell 12 is the same as that of the shell 12 and is lower than that of the solution contained in the inner container 11, and because the temperature of the shell 12 is usually lower than that of the heat-conducting liquid 15, when the cup is stopped to shake and is placed on the front, the gas of the low-boiling-point liquid 15 is quickly liquefied into the low-boiling-point liquid 15, and the liquefaction process is a heat-releasing process, a large amount of heat is released, and is absorbed by the shell 12 with relatively low. The low boiling point liquid 15 is liquefied into liquid and deposited at the bottom of the sealed space 14, so that the sealed space 14 is in a vacuum or semi-vacuum state, and a good heat preservation effect is achieved.
When ice water, cold water or ice water mixture is filled into the inner container 11, the filled object can keep low temperature for a long time, when people want to ice compress, the cup body is shaken, so that the low-boiling-point liquid 15 of the cup body is in back-and-forth contact between the inner container 11 and the outer shell 12, the low temperature of the inner container 11 is transferred to the outer shell 12, the temperature of the outer shell 12 is reduced, and the cup is placed at a position needing ice compress, so that comfortable ice compress can be carried out.
