Description

[Technical field]

[0001] The invention relates to the field of automatic temperature protection and automatic dispensing containers, in particular to a switch device with automatic temperature protection and applied to automatic dispensing, and a water cup and an electrolysis cup for automatically dispensing temperature-sensitive tea, milk powder or medicine at an appropriate temperature. [Background technology]

[0002] The water cup insulation bag container is generally a container made of ceramic or stainless steel with a vacuum layer, such as a sealed container, such as a sealed container for holding water, such as a thermos cup or a thermos pot. Since the vacuum insulation layer can delay the heat dissipation of the liquid inside, such as water, this type of insulation container has the function of long-term and efficient heat preservation.

[0003] At present, large-capacity thermal insulation containers such as thermos cups or thermos pots, especially travel thermos cups or thermos pots, generally have a drinking lid. The lid is removed, the sealing valve is opened, and hot water is poured into the lid for drinking. However, due to the good thermal insulation performance of the thermos cup or thermos pot, the water just poured into the drinking lid is too hot to be drunk immediately, and a long time is required, which does not achieve the effect of drinking water immediately to quench thirst.

[0004] Moreover, in order to cater to the market, many thermos cup products are now provided with an interlayer for placing tea leaves, medicines, etc., so that users can use them directly through the thermos cup. However, the existing thermos cups cannot achieve the function of isolating the liquid in the cup from contacting the objects placed in the interlayer. In daily use, it is often found that the brewing temperatures of medicines, tea leaves, milk powder, food, instant powders and some civilian products are different. The soaking temperature and time will affect the use effect and the taste of the drinker. However, in daily life, people wait for the water to boil and then let it stand for a while to cool naturally. When the water temperature is suitable, they will pour it directly into the cup, which will directly contact with the instant powders and other materials in the cup, and they cannot control the suitable water temperature, which affects the use effect and the taste of the drinker. [Summary of the invention]

[0005] In order to solve the problem that the thermos cup in the prior art cannot achieve the function of isolating the liquid in the cup from the contact between the interlayer placed objects, the present invention provides an automatic temperature control switch device applied to a water cup, an electrolytic cup that can cool down quickly, and an electrolytic cup that can cool down quickly.

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The present invention is achieved through the following technical solutions:

[0032] like Figure 1 , Figure 5 , Figure 6 As shown, the switch device for automatic temperature protection and automatic dispensing comprises a base 1, a channel is provided on the base 1, and an automatic switch 2 is also provided on the base 1, which is opposite to the channel and automatically opens or closes the channel according to the temperature outside the base 1. The present invention provides a switch device for automatic temperature protection and automatic dispensing, which can be directly applied to the interlayer in the water cup, and the automatic switch is used to automatically open or close according to the water temperature in the cup, so as to isolate or connect the liquid in the cup with the interlayer. Moreover, the device can be used alone in the existing water cup, and its structure is simple, which is convenient for wide use.

[0033] Moreover, a temperature control layer of a temperature-controllable phase change material is provided on the shell 1, and the liquid entering the shell can be quickly cooled down. For example, by selecting the opening temperature of the automatic switch to be between 60 and 80°C, when 80°C water enters the shell, the temperature control layer can be used to quickly cool the water in the shell, for example, to 60°C, so that the drinker can drink quickly.

[0034] Furthermore, the phase change material is selected from a higher aliphatic hydrocarbon having 18 to 26 carbon atoms, such as a higher aliphatic hydrocarbon having 18, 19, 20, 21, 22, 23, 24, 25 or 26 carbon atoms, an alkane type paraffin having a melting point of 30°C to 60°C, such as an alkane type paraffin having a melting point of 30, 40, 50 or 60°C, a fatty alcohol having 13 to 18 carbon atoms, such as a fatty alcohol having 13, 14, 15, 16, 17 or 18 carbon atoms. The phase change material is selected from the group consisting of an alcohol, a polyethylene glycol with a molecular weight of 800 to 6000, such as a polyethylene glycol with a molecular weight of 800, 900, 1000, 2000, 4000 or 60000; more preferably, the phase change material is selected from the group consisting of a higher aliphatic hydrocarbon with a carbon number of 18 to 26 and an alkane type paraffin with a melting point of 30°C to 60°C; further preferably, the phase change material is an alkane type paraffin with a melting point of 30°C to 60°C.

[0035] Further, in the present invention, a phase change material with high thermal conductivity can be used. In some preferred embodiments, the thermal conductivity of the temperature control layer is 0.2 to 20 W / m·K, for example, 0.2, 0.4, 0.8, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 W / m·K. In order to improve the thermal conductivity of the phase change material so that the drinking water thermos cup or the thermos pot lid can quickly cool the contents therein, in some preferred embodiments of the present invention, a filler with high thermal conductivity, sometimes referred to herein as a "high thermal conductivity filler" or "thermally conductive filler", is mixed or compounded with a phase change material such as the above-mentioned phase change material to obtain a high thermal conductivity phase change material with the above-mentioned thermal conductivity. In this case, the above-mentioned temperature control layer comprises a phase change material and a thermally conductive filler.

[0036] In addition, the thermally conductive filler is selected from the group consisting of aluminum powder, copper powder, graphite powder, nano aluminum nitride, carbon fiber, graphene, and expanded graphite. More preferably, the thermally conductive filler is selected from the group consisting of carbon fiber, graphene, and expanded graphite; further preferably, the thermally conductive filler is selected from the group consisting of graphene and expanded graphite, because such a material has a flaky structure, and each flaky structure overlaps each other and exists in the material, so it has a more superior thermal conductivity than, for example, a material that exists in spherical particles. This may be because the contact area between each particle of the spherical particle material is small, and sometimes there is even a situation where adjacent particles do not contact each other inside the material. In addition to improving thermal conductivity, thermally conductive fillers can also be used to change the phase change state of phase change materials, for example, solid-liquid phase change materials can be changed into solid-solid phase change materials, thereby reducing the fluid of the phase change material.

[0037] Furthermore, the base 1 includes a shell 11 having a accommodating cavity 101, a lower shell 12 detachably sealed and connected to the shell 11, the channel is arranged on the lower shell 12, and the automatic switch 2 is a bimetallic strip arranged on the lower shell 12 and deformed according to the temperature. The bimetallic strip used in this metal strip is also called a thermal bimetallic strip. Since the thermal expansion coefficients of each component layer are different, when the temperature changes, the deformation of the active layer is greater than the deformation of the passive layer, so that the whole bimetallic strip will bend toward the passive layer, and the curvature of this composite material will change to produce deformation. Among them, the one with a higher expansion coefficient is called the active layer; the one with a lower expansion coefficient is called the passive layer. A simple structure is used to realize automatic switching according to the temperature of the liquid in the cup.

[0038] Furthermore, the lower shell 12 can be connected to the outer wall of the accommodating chamber 101 through a threaded connection portion and further sealed by a sealing ring, so that the interior of the accommodating chamber can be easily disassembled and cleaned.

[0039] Of course, the lower shell 12 can also be sealed and connected by a snap-fit ​​structure.

[0040] Specifically, the automatic switch 2 includes a first bimetallic strip 31 and a second bimetallic strip 32 provided on the lower housing 12, the first bimetallic strip 31 is located in the accommodating cavity 101, the second bimetallic strip 32 is located outside the accommodating cavity 101, and the first bimetallic strip 31 and the second bimetallic strip 32 are both opposite to the channel on the lower housing 12. A connecting hole is provided in the middle of the first bimetallic strip 31 and the second bimetallic strip 32, and the first bimetallic strip 31 and the second bimetallic strip 32 are both circular bimetallic strips, the first bimetallic strip 31 includes a deformable bending deformation portion 311, and a circular ring portion 312 provided outside the bending deformation portion 311 for contacting with the end surface of the lower housing 12 to form a seal; the second bimetallic strip 32 includes a deformable second bending deformation portion 321, and a second circular ring portion 322 provided outside the second bending deformation portion 321 for contacting with the end surface of the housing 21 to form a seal. The overall outer diameter of the first metal sheet 31 is larger than the diameter of the channel on the lower shell 12 and smaller than the inner diameter of the accommodating chamber 101. The channel on the lower shell 12 is also an annular opening, or an opening composed of multiple holes, which ensures that after the first bimetallic sheet 31 or the second bimetallic sheet 32 ​​is deformed, it can be within the range covered by the metal sheet.

[0041] Moreover, by utilizing the characteristic that the bimetallic strip deforms only at different temperatures, the device can be opened only within a specific temperature range. For example, the first bimetallic strip is made of a metal that opens only at temperatures above 40°C, and the second bimetallic strip is made of a metal that opens only at temperatures below 60°C and closes at temperatures above 60°C. The water temperature can be controlled to be between 40°C and 60°C to pass through the device.

[0042] Embodiment 2

[0043] The difference from the above is that the accommodating cavity 101 on the shell 11 passes through the upper and lower end surfaces of the shell 11, and the upper end of the shell 11 is also provided with an upper shell that is detachably and sealedly connected to the shell 11, and the upper shell is also provided with the automatic switch 2. Both ends of the shell 11 are automatically opened or closed by the automatic switch 2, which can prevent the water temperature from being too high when adding water from the upper end and affecting the temperature of the existing liquid.

[0044] Moreover, the structure of the shell 11 can be as follows: the shell 1 includes an outer cylinder shell 41, an inner cylinder wall 42, and a temperature control layer 43 made of a phase change material and arranged between the outer cylinder shell 41 and the inner cylinder wall 42. The liquid entering the shell 11 can be cooled by the temperature control layer, while the liquid outside the shell is not affected.

[0045] like Figure 3 , Figure 4 As shown, the electrolysis cup capable of automatic temperature-adaptive electrolysis comprises a water cup body 5, a water storage chamber 401 is provided in the water cup body 5, an electrolysis device 6 is also provided in the water storage chamber 401, and the electrolysis device 6 is provided with an automatic switch 2 as claimed in any one of claims 1 to 7. The present invention also provides an electrolysis cup capable of automatic temperature-adaptive electrolysis, and the above-mentioned switch device is used to realize electrolysis at a specific temperature, and high-temperature protection of the electrolysis unit can be realized, and the electrolysis function can be automatically turned on at the optimal temperature. The bimetallic strip assembly comprises a soft, food-grade outer shell, and comprises: at room temperature, the bimetallic strip is tilted as a whole to realize the opening of the electrolytic cell, and at high temperature, the bimetallic strip is deformed to be straight or bent downward to realize the closing of the opening of the electrolytic cell; the bimetallic strip type temperature protection device preferably has a protection temperature range of 40-60°C, and more preferably 40-50°C.

[0046] The electrolysis device is also provided with an SPE membrane, which can play a certain filtering role and ensure the health of the drinker.

[0047] Moreover, the water cup body 5 may also be a structure including an outer cylinder shell 41, an inner cylinder wall 42 connected to each other, and a temperature control layer 43 made of phase change material disposed between the outer cylinder shell 41 and the inner cylinder wall 42. The phase change material is used to achieve the functions of rapid cooling and heat preservation.

[0048] In addition, the water cup body 5 is also provided with a temperature detector 7 for detecting the temperature in the water storage chamber 401 and a protection switch 8 opposite to the automatic switch 2. Automatic electrolysis can also be set when the set temperature is reached, and an audible and visual alarm can be sounded after the electrolysis is completed. The temperature detector can be a commonly used temperature sensor, which can be electrically connected to the circuit of the electrolysis device to set the water temperature to reach a certain value before electrolysis occurs, and can maintain the highest electrolysis efficiency. After adding the automatic switch and the protection switch 8, the temperature protection device of the bimetallic strip assembly in the cup body can be used to close the opening of the electrolytic cell. When the bimetallic strip is deformed, the protection switch is triggered to stop the electrolysis work; when the temperature protection device in the cup body opens the opening of the electrolytic cell, the protection switch is released, that is, the electrolytic cell can be electrolyzed at this time.

[0049] like Figure 2 As shown, the present invention also provides a water cup with automatic temperature-appropriate dispensing, including a water cup body 5, wherein a first chamber 501 and a second chamber 502 communicating with the first chamber 501 are provided in the water cup body 5, and an automatic switch 2 is provided at the connection between the first chamber 501 and the second chamber 502. The second chamber 502 is equivalent to an interlayer, and the switch made of a bimetallic sheet is used to automatically block the connection between the first chamber and the second chamber, so as to prevent the tea or medicine in the second chamber from being soaked all the time and affecting the taste.

[0050] The present invention provides a switch device for automatic temperature protection and automatic delivery, which can be directly applied to the interlayer in the water cup, and the automatic switch is used to automatically open or close according to the water temperature in the cup, so as to isolate or connect the liquid in the cup with the interlayer. Moreover, the device can be used alone in the existing water cup, and its structure is simple and convenient for wide use. The switch device for automatic temperature protection and automatic delivery of the present invention can be used through a shell with a accommodating cavity and a lower shell with a detachable sealing connection, and tea leaves and the like can be put into the shell, and directly thrown into the water cup or kettle container through the device. Its greatest advantage is that an automatic switch is provided on the channel between the accommodating cavity and the outside world, and it is opened only when the temperature reaches a suitable set temperature, thereby controlling a suitable tea brewing temperature.
