Description

Cream knife with quick thawing function

This creation is about a cream knife, especially a cream knife that uses the principle of a heat pipe to conduct body temperature to the blade and quickly unfreeze the cream piece.

According to the cream, the cream is a daily food in many parts of the world. It is mainly made from milk or fresh cream. It can be directly used as a seasoning on food and used in cooking, because the cream is dispersed in The composition of tiny droplets in milk fat will soften at about 15 degrees Celsius, becoming a smearable state, that is, a state of eating, and melting into a thin liquid at about 32 to 35 degrees Celsius. Therefore, the cream is usually placed in the refrigerator freezer to maintain its solid state to extend its shelf life, but this also makes the cream block often too hard to be eaten immediately when it is just taken out of the refrigerator, which is busy and demanding. For the users of aging, it is really a big problem.

Therefore, in order to overcome the problem that the conventional cream knife is not easy to cut the cream piece or to quickly thaw and melt it to the smearable state, a manufacturer has developed a cream knife which is automatically heated, and has a heating button on the handle. When you use it, just press and hold the heating button, the front end of the knife will heat up, put it on the frozen cream to heat it and melt it, which has good convenience. However, this design can solve the above-mentioned conventional problems and seems to be very convenient, but because it needs to be equipped with a heating device inside, and must rely on the battery or external power supply for heating, not only will the manufacturing, use and subsequent maintenance costs be improved. And it is completely inconsistent with the modern people's pursuit of environmental protection and energy saving and carbon reduction.

In view of this, the creator adheres to the spirit of research and innovation, and strives for improvement, and then improves the lack of the aforementioned products, and finally develops a cream knife with a quick thawing function.

The technical problem to be solved by the present invention is to overcome the disadvantages of the conventional cream knife which is not easy to thaw and melt the cream piece, and needs to be heated by the heating device. The main purpose of this creation is to use the principle of heat pipe, so that the cream knife can be quickly thawed by hand warming, which has the practical functions of saving time and energy saving and carbon reduction.

In order to achieve the above objectives, the technical problem of the creation is achieved by the following technical solutions. According to the present invention, a "cream knife with a quick defrosting function" is proposed, which comprises a cutter body, which is integrally formed by metal machining, and includes a shank portion and a blade portion, and the shank portion is disposed at the blade portion One of the main features is that the cutter body is internally provided with a closed cavity connecting the shank portion and the blade portion, and the closed cavity system is evacuated and sealed with a proper amount of working fluid therein. The fluid is pure water or natural cold coal.

Further, the blade portion can be set as a single edge or a double edge to meet the needs of different users.

Furthermore, the closed cavity is provided with a capillary structure to improve heat transfer efficiency.

In summary, this creation can mainly achieve the following advantages and effects:

1. This creation uses the principle of heat pipe. When the user holds the shank, the heat generated by the body temperature will be thermally transferred by the phase change of the working fluid, so that the blade portion and the shank portion form an isothermal state. After the warming of the blade, the melted and cut cream pieces can be easily thawed, which saves the time for waiting for the cream block to be warmed and thawed, and has excellent convenience.

2. The working fluid sealed in the closed cavity of the tool body is pure water or natural cold coal which is harmless to the human body and the environment, and has the practicality of improving the heat conduction efficiency, thereby enhancing the industrial value of the creation.

3. Through the structural improvement, the creation only needs to use the human body temperature for heat conduction to solve the long-standing problem. Moreover, the creation does not need to provide a heating device, and does not need to be connected to a battery or an external power supply, in addition to reducing manufacturing and maintenance. Cost, and can meet the environmental protection concept of modern people's energy saving and carbon reduction.

4. The creation is made of metal processing. It can be made of copper or aluminum with good thermal conductivity and heat dissipation. The formed tool body can be surface-processed by electroplating or antibacterial treatment to enhance the resistance of the finished product. Corrosive, durable and textured.

In the following, the specific embodiments and the accompanying drawings are explained in detail, and it is easier to understand the purpose, technical content, characteristics and effects achieved by the present invention.

First, as shown in Figures 1 to 3-4, the present invention is a cream knives having a quick defrosting function, which includes a cutter body 1 which is integrally formed by metal processing, which can be copper. Or a material having good thermal conductivity and heat dissipation, such as aluminum, the tool body 1 includes a shank portion 11 and a blade portion 12, and the shank portion 11 is provided at one end of the blade portion 12, and the blade portion 12 can be set to be unilateral The cutting edge 121 has a closed cavity 13 connecting the shank portion 11 and the blade portion 12, and the closed cavity 13 is vacuumed and sealed in the closed cavity 13 A suitable amount of working fluid (not shown) is pure water or natural cold coal.

Referring to Figures 4 and 5, another embodiment of the present invention differs from the previous embodiment in that the blade portion 12a of the tool body 1a is provided with a bilateral blade 121a to cater for different users. Further, the present invention can further provide a capillary structure (not shown) in the closed cavity 13, and the capillary structure can be a sintered type, a groove type or a metal mesh type, thereby effectively improving The heat transfer efficiency, but the capillary structure is a well-known technique, so it will not be repeated here.

In addition, the surface of the formed tool body 1, 1a can be processed by surface treatment technology, such as electroplating or antibacterial treatment such as nickel plating or gold plating, on the one hand, the product can be rustproof and corrosion resistant, and more Durable; on the other hand, it can make the finished product more beautiful and improve the texture of the finished product.

With the above structural design, when the user takes out the cream piece which is hard from the refrigerator and presents a hard shape, the user only needs to hold the shank portion 11 of the present cream knife, and the heat generated by the human body temperature passes through the closed cavity. The phase change of the working fluid in the body 13 is rapidly conducted, and the blade portion 12 and the shank portion 11 are isothermally formed in a short time, and the blade portion 12 after the temperature rise is sufficient for easy cutting or making the cream block. Thawing and melting, which is convenient for users to apply cream on food, can save time and convenience and meet the practical effect of energy saving and carbon reduction.

In summary, the creation of "a cream knife with a quick defrosting function" can eliminate the drawbacks of the traditional ones, and enhance the practicality and progress without any doubt, and the technical means and structural features disclosed in the foregoing embodiments. It has never been disclosed before, and it does not lose its novelty. However, the above is only the preferred embodiment of this creation. When it is not possible to limit the scope of this creation, the scope of application of this new patent and The simple equivalent changes and modifications made by the new description are still within the scope of this new patent.
