Description

Technical Field

[0001] This invention relates to the field of thermos cups, and more specifically, to a stainless steel thermos cup that displays temperature. Background Technology

[0002] Currently, many thermos flasks can display temperature; however, the batteries that power the temperature display need to be replaced. Furthermore, if the battery leaks, harmful substances inside can seep into the beverage inside the thermos, posing a health risk.

[0003] In addition, existing insulated cups use sealing rings, which are mostly made of silicone. Generally, silicone is harmless to the human body; however, a small percentage of people may experience allergic reactions, such as itchy, red, and rashes, as well as difficulty breathing and dizziness. Furthermore, although silicone is normally harmless, using inferior silicone or adding substandard ingredients during manufacturing can still pose certain health risks.

[0004] Another problem with silicone sealing rings is that after a period of use, mold can grow on or near the silicone sealing ring, forming a black, unclean substance. If not cleaned promptly, this can pose a health hazard. Unfortunately, many people do not regularly remove and clean the sealing ring inside their thermos. Summary of the Invention

[0005] To overcome the shortcomings of existing thermos cups, this invention provides a thermos cup with a temperature display that does not require battery replacement. Furthermore, this thermos cup does not use any sealing rings, and all materials used in contact with liquid beverages are food-grade stainless steel.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A stainless steel thermos cup for displaying temperature includes a stainless steel lid 1, a stainless steel protrusion 2, a photovoltaic chip 3, a voltage amplifier 4, a rechargeable battery 5, a temperature display 6, a temperature sensor 7, a sealing thread 8, and a stainless steel cup body 9.

[0008] The stainless steel cup lid 1 is equipped with a temperature display 6 and a photovoltaic power generation chip 3.

[0009] The stainless steel cup lid 1 has a tapered stainless steel protrusion 2 below it. The stainless steel protrusion 2 has a vacuum chamber 2A inside it, and the outer tapered surface of the stainless steel protrusion 2 is polished.

[0010] The stainless steel cup body 9 includes a vacuum chamber 9A and a stainless steel inner wall 9B.

[0011] The inner side of the stainless steel cup lid 1 is machined with a female thread 8B for sealing pipe threads.

[0012] The outer side of the top of the stainless steel cup body 9 is machined with a male thread 8A for sealing pipe threads, and the top of the stainless steel cup body 9 is polished.

[0013] The temperature display 6 is placed above the rechargeable battery 5, which is placed above the voltage amplifier 4, which is placed above the thermal photovoltaic chip 3.

[0014] The temperature sensor 7 is placed on the side of the thermal photovoltaic chip 3. The positive and negative terminals of the rechargeable battery 5 are connected to the positive and negative terminals of the temperature display 6, and the positive and negative terminals of the thermal photovoltaic chip 3 are connected to the positive and negative terminals of the rechargeable battery (5).

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The thermoelectric power generation technology utilizes the temperature difference between the liquid beverage inside the thermos and the ambient temperature to generate electricity, powering the rechargeable battery of the temperature display unit, which does not need to be replaced. This makes the temperature display unit maintenance-free. Because the all-steel thermos does not use any sealing rings, and all materials in contact with the liquid beverage are made of food-grade stainless steel, it will not produce any harmful substances that are detrimental to health, making it clean and hygienic.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0023] like Figures 1 to 3 As shown, a stainless steel thermos cup with temperature display includes a stainless steel lid 1, a stainless steel protrusion 2, a photovoltaic chip 3, a voltage amplifier 4, a rechargeable battery 5, a temperature display 6, a temperature sensor 7, sealing threads 8, and a stainless steel cup body 9. Each time hot water is poured into the thermos cup, a temperature difference exists between the upper and lower surfaces of the photovoltaic chip, generating electricity to charge the battery, thus eliminating the need for battery replacement. The battery powers the temperature display, and the voltage amplifier increases the voltage of the photovoltaic chip to the minimum voltage required by the temperature display.

[0024] Preferably, the top surface of the temperature display 6 is placed on top of the cup lid so that the user can see the displayed temperature. The bottom surface of the temperature display 6 is placed above the rechargeable battery 5 so that the positive and negative terminals of the battery can be connected to the positive and negative terminals of the temperature display. The rechargeable battery 5 is placed above the voltage amplifier 4, which in turn is placed above the photovoltaic chip 3. This placement method helps to reduce the length of the conductive wire. The temperature sensor 7 is placed on the side of the photovoltaic chip 3 to measure the temperature of the liquid inside the thermos.

[0025] Preferably, the positive and negative terminals of the rechargeable battery 5 are connected to the positive and negative terminals of the temperature display 6 to power the temperature display. The positive and negative terminals of the thermal photovoltaic chip 3 are connected to the positive and negative terminals of the voltage amplifier, which boosts the voltage of the thermal photovoltaic chip to the minimum voltage required by the temperature display.

[0026] Preferably, a tapered stainless steel protrusion 2 is provided at the bottom of the stainless steel lid 1. The outer tapered surface of the stainless steel protrusion 2 is polished. Due to the tapered nature and polishing of this stainless steel protrusion, when the lid 1 is tightened downwards, the outer side of the stainless steel protrusion 2 contacts the top of the thermos body, achieving a seal and ensuring that the liquid inside the cup does not leak. A vacuum chamber 3A is provided inside the stainless steel protrusion 2. This vacuum layer can act as insulation in the upper part of the thermos, preventing heat loss from the top and achieving a heat preservation effect. At the same time, the design of the vacuum chamber 3A not only saves stainless steel material but also gives the stainless steel protrusion 2 better elasticity. When the lid 1 is tightened downwards, the outer side of the stainless steel protrusion can achieve stronger contact and a better seal with the top of the thermos body.

[0027] Preferably, the inner side of the stainless steel cup lid 1 is machined with a female thread 8B for sealing pipe threads. This female thread and the male thread 8A on the outer side of the top of the stainless steel cup body 9 can form a further seal to ensure that the liquid inside the cup body does not leak.

[0028] Preferably, the stainless steel cup body 9 has a vacuum chamber 9A inside. This vacuum layer can provide insulation on the sides of the thermos cup, preventing heat loss from the surrounding area of ​​the cup body. All materials in contact with the liquid are made of food-grade stainless steel, while other parts can be made of ordinary stainless steel.

[0029] Preferably, the outer side of the top of the stainless steel cup body 9 is machined with a male thread 8A for sealing pipe threads. This male thread 8A and the female thread 8B on the outer side of the top of the stainless steel cup body 9 can form a further seal, ensuring that the liquid inside the thermos does not leak. The top of the stainless steel cup body 9 is polished, and when the cup lid 1 is tightened, it contacts the outer side of the stainless steel protrusion 2 to achieve a seal and ensure that the liquid inside the cup does not leak. To prevent the stainless steel thermos from slipping easily when held, the cup body 9 can also be curved.

[0030] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
