High-efficiency heat-conduction glass heating container and manufacturing method thereof

Technical Field

The invention relates to a high-efficiency heat-conduction glass heating container and a manufacturing method thereof.

Background

At present, the existing kettles on the market are various, such as stainless steel kettles, glass kettles and IH heating kettlesMilk mixing kettles, full glass kettles and the like, but the kettles all have more or less defects: heating components of stainless steel kettles and glass kettles are arranged at the bottom of a kettle body, the bottom of the kettle body is generally made of stainless steel materials which are contacted with water, the surface of the kettle body needs to be polished, and the polishing process is difficult to avoid dust brought in after polishing, so that rusts with different degrees can be caused to appear in the heating process to pollute the water; since the water is generally weakly alkaline, it contains Ca (HCO)₃)₂Dirt such as incrustation scale and the like generated after the kettle body is heated is easy to deposit on the heating plate, the kettle body cannot be completely put into water for thorough cleaning, and the drinking water quality cannot be guaranteed due to the dirt carried by the kettle body all the year round.

The IH heating milk mixing device is characterized in that a magnetic conductive material is fixed on the bottom of the glass cup body, so that liquid in the glass cup is electromagnetically heated through the heating base with the electromagnetic heating function, and the IH heating milk mixing device has the following defects: electromagnetic radiation can be generated during electromagnetic heating, the nursing device can bring physical injury to pregnant women and infants, is not suitable for the requirements of the nursing device in the field of mother and infant products on human health, and is high in manufacturing cost by adopting the electromagnetic heating technology, and restriction on wide use and sale of products is generated.

As another example, the whole glass kettle is made of whole glass, so that the whole glass kettle is highly attractive, and is purchased by customers due to the love to the appearance of the kettle, but tests show that 1200ml of water filled in the whole glass kettle needs more than one hour when the temperature is increased from 25 ℃ to 100 ℃, the heating efficiency is extremely low, and in order to improve the heating efficiency, for example, the glass heating container and the manufacturing method thereof in the invention of chinese application No. 202010692045.5, the coating is plated on the bottom of the glass cup, so that the heating time can be prolonged, but the processing cost is high, the manufacturing process is complex, and in the heating process, a small amount of coating molecules pollute water sources due to the molecular motion phenomenon, and the whole glass kettle is particularly not suitable for the requirements of milk conditioners in the mother and baby fields on the health of human bodies.

(1) blowing the glass heating container into a blank according to the shape requirement, wherein the bottom surface of the blank is flat, and the flatness tolerance of the bottom surface of the blank is about 0.3 mm;

(2) carrying out water grinding and flattening treatment on the bottom surface of the blank body to control the flatness of the blank body to be 0.03-0.2 mm;

(3) finally, grinding and polishing the bottom surface of the blank to ensure that the bottom surface is kept flat and bright and the flatness tolerance is controlled to be less than 0.02 mmmm;

(4) the plastic handle is designed into a certain shape according to human engineering, and then is bonded on the glass body through a high-strength adhesive, and the contact area between the glass body and the plastic handle is 30cm²The gap can not exceed 0.3 mm.

Further, the high strength adhesive is required to have water and temperature resistance of more than 100 ℃ and simultaneously to have a property of per cm²The adhesion pull is greater than 1 kgf.

(III) advantageous effects

Compared with the prior art, the invention has obvious advantages and beneficial effects, particularly, the flatness tolerance of the bottom surface of the glass cup is smaller than 0.02mm, the heating disc surface heating with the same surface flatness is matched, the time for heating 1200ml of water from 25 ℃ to 100 ℃ in the glass heating container is only within 15 minutes, the heat conduction efficiency is improved by nearly 4 times compared with the heat conduction efficiency of the common heating glass, the heating glass container can be directly used for liquid heating, a metal heating disc is not required to be installed in a hollow manner at the bottom of the glass cup, the timeliness is poor, the advantages of subversion are realized, the bottom of the glass cup is not provided with the metal heating disc, a silica gel sealing ring of the heating disc is not required, the complex installation process and cost are avoided, the quality problems of poor sealing of the glass cup, the rusting of the heating disc and the smell of silica gel are avoided, the structure is simple, and the glass cup can be directly and wholly, the glass cup has the advantages that the glass is safe and environment-friendly, the hidden danger that the heavy metal of water or food exceeds the standard caused by the fact that metal contacts water and food does not exist, the glass cup is simple to process, low in manufacturing cost and easy to sell, the water pollution to a human body cannot be caused, and meanwhile, the heating efficiency is high.
