Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to a novel feeding bottle. Background Art

[0002] Current baby bottles are often made of plastic. When placed on a heated base, they form a milk warmer, typically using a heating tube, hot air heating (ceramic heater with fan), or steam heating. These heating methods transfer heat to the bottle, heating the liquid inside. This results in a low heat transfer rate and heating efficiency, as the liquid inside is heated through the bottle. Since the bottle is made of plastic, hot air heating (ceramic heater with fan) or steam heating (boiling water) also have low thermal conductivity.

[0003] In addition, the bottom of the feeding bottle is usually not detachable, and if milk powder is deposited on the bottom of the feeding bottle, it is difficult to clean.

[0004] Therefore, further improvement is needed. Utility Model Content

[0005] The present invention discloses a new type of baby bottle with a metal heat conductor installed at the bottom of the bottle body. A liquid storage chamber is formed between the metal heat conductor and the inner cavity of the bottle body. The baby bottle can be heated directly on an induction cooker, or equipped with a corresponding induction heating base. This utilizes the same principle as induction cookers heating stainless steel, based on electromagnetic induction. When the induction cooker is powered on, the coil inside it generates a high-frequency alternating magnetic field. When a baby bottle with a ferromagnetic metal heat conductor is placed on the induction cooker, this alternating magnetic field passes through the bottom of the bottle, causing eddy currents to form within the iron atoms within the metal heat conductor. These eddy currents are converted into heat energy by the electrical resistance of the stainless steel or titanium (metal heat conductor), thereby heating the liquid within the bottle. Direct contact and heating of the liquid within the bottle with the metal heat conductor ensures high heat conduction and transfer efficiency, as well as efficient conversion and utilization of thermal energy.

[0006] The bottle can also be placed directly on an electric ceramic stove or a heating base with a heating tube for heating. The metal heat conductor directly transfers heat to the liquid in the bottle, with high thermal conductivity efficiency.

[0007] A new type of feeding bottle designed for this purpose includes a metal heat conductor and a bottle body with a through opening at the bottom. The metal heat conductor is arranged at the through opening at the bottom of the bottle body, and a liquid storage cavity is formed between the bottle body and the metal heat conductor.

[0008] The bottle body is made of PP, PPSU, silicone or glass, and the metal heat-conducting component is made of food-grade 304 stainless steel, food-grade 316 stainless steel or pure titanium.

[0009] A positioning groove is provided on the bottom opening of the bottle body, and the metal heat conducting member is positioned on the positioning groove;

[0010] The bottom of the metal heat conducting member is a planar structure, or the bottom of the metal heat conducting member includes a planar segment and an arc segment forming a transition connection with the planar segment.

[0011] The metal heat conducting member is arranged at the bottom opening of the bottle body, and the metal heat conducting member serves as the bottom surface supporting the bottom of the bottle body;

[0012] Alternatively, a bottom cover is provided on the bottom of the bottle body, and the metal heat conducting member is arranged between the bottle body and the bottom cover.

[0013] A portion of the bottom of the metal heat conductor is suspended on the bottom cover, and another portion of the bottom of the metal heat conductor is supported on the bottom cover;

[0014] Alternatively, the bottom of the metal heat conducting member is completely supported on the bottom cover.

[0015] A suspended space L is provided between the bottom of the metal heat conductor and the top of the bottom cover to form a heat insulation layer;

[0016] The bottom cover is provided with a recessed portion for forming a suspended space L with the bottom of the metal heat conducting member;

[0017] The bottom cover is provided with air holes communicating with the outside air, and the air holes are arranged on the bottom and / or side of the bottom cover.

[0018] A positioning groove for mounting a metal heat conductor is provided on the bottom opening of the bottle body, and a sealing ring or injection molding glue is used to form a sealing fit between the metal heat conductor and the positioning groove.

[0019] The outer diameter of the metal heat conductor is larger than the inner diameter of the positioning groove, so that an interference seal is formed between the metal heat conductor and the positioning groove; or, a sealing ring is provided on the outer peripheral side of the metal heat conductor, and the metal heat conductor abuts against the inner peripheral side of the positioning groove through the sealing ring, so that a sealing fit is formed between the metal heat conductor and the positioning groove through the sealing ring.

[0020] The bottle body, the metal heat-conducting member and the bottom cover are formed into an inseparable whole by gluing or injection molding;

[0021] Alternatively, the metal heat conducting element itself is elastically deformed, and the sealing ring or threaded structure is detachably mounted on the bottom opening of the bottle body;

[0022] The metal heat conductor is provided with a connecting portion that is threadedly connected to the bottle body, and the connecting portion is provided with an external thread or an internal thread that is connected to the bottle body, and the connecting portion and the metal heat conductor are formed into an inseparable whole;

[0023] The feeding bottle further comprises a nipple detachably connected to the opening at the top of the bottle body, and a milk cap, the milk cap being covered on the bottle body and covering the nipple;

[0024] The feeding bottle further comprises a heat-insulating shell which is sleeved on the outer side of the bottle body.

[0025] The beneficial technical effects of the utility model are as follows:

[0026] A metal heat conductor is provided on the bottom of the bottle body of the feeding bottle, and a liquid storage cavity is formed between the metal heat conductor and the inner cavity of the bottle body. When the metal heat conductor serves as the supporting surface of the bottom of the bottle body, the feeding bottle can be directly placed on an induction cooker, an electric ceramic cooker, and a heating base with a heating tube for heating, or the feeding bottle can be equipped with a corresponding electromagnetic heating base, and the liquid in the feeding bottle is directly in contact with the metal heat conductor for heating, so that the heat conduction and heat transfer efficiency is high, and the heat energy conversion and utilization efficiency is high.

[0027] When the metal heat conductor is placed between the bottom of the bottle and the bottom cap, the bottle can be placed directly on an induction cooker, or the bottle can be equipped with a corresponding induction heating base. This utilizes the same principle as induction cookers heating stainless steel, based on the phenomenon of electromagnetic induction. When the induction cooker is powered on, the coil inside it generates a high-frequency alternating magnetic field. When a bottle with a ferromagnetic metal heat conductor is placed on the induction cooker, this alternating magnetic field passes through the bottom of the bottle, causing eddy currents to form within the iron atoms inside the metal heat conductor. These eddy currents are converted into heat energy by the electrical resistance of the stainless steel or titanium (metal heat conductor), thereby heating the liquid in the bottle. The liquid in the bottle is directly in contact with the metal heat conductor and heated, resulting in high thermal conductivity and heat transfer efficiency, as well as high thermal energy conversion and utilization efficiency.

In this way, the metal heat conductor can be removed from the bottom opening of the bottle body for cleaning, which is convenient for users to clean the bottom of the bottle, prevent stains on the electric heat conductor, and ensure the cleanliness of drinking.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all the embodiments. In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0040] First embodiment:

[0041] See also Figure 1 A new type of feeding bottle includes a metal heat conductor 2 and a bottle body 1 with a through opening at the bottom. The metal heat conductor 2 is arranged at the through opening at the bottom of the bottle body 1, and a liquid storage cavity is formed between the bottle body 1 and the metal heat conductor 2.

[0042] The bottle body 1 is made of PP, PPSU, silicone or glass, and the metal heat conductor 2 is made of food-grade 304 stainless steel, food-grade 316 stainless steel or pure titanium.

[0043] The bottom of the metal heat conductor 2 is a planar structure, or the bottom of the metal heat conductor 2 includes a planar segment and an arc segment forming a transition connection with the planar segment. The combination of the planar segment and the arc segment effectively increases the heat conduction area of ​​the metal heat conductor 2.

[0044] The metal heat conducting member 2 is arranged at the bottom opening of the bottle body 1 , and the metal heat conducting member 2 serves as the bottom surface supporting the bottom of the bottle body 1 .

[0045] When the metal heat conductor 2 serves as the support surface for the bottom of the bottle body 1, the bottle can be placed directly on an induction cooker, an electric ceramic cooker, or a heating base with a heating pipe for heating. Alternatively, if the bottle is equipped with a corresponding electromagnetic heating base, the liquid in the bottle directly contacts the metal heat conductor for heating, resulting in high heat conduction and heat transfer efficiency and high thermal energy conversion and utilization efficiency. The metal heat conductor 2 directly contacts the heat conducting surface of the induction cooker, electric ceramic cooker, or heating base with a heating pipe.

[0046] In this embodiment, the metal heat conductor 2 is provided with a step portion at the bottom. When the metal heat conductor 2 is placed on the mold cavity of the injection-molded bottle body 1, the molten plastic flows to the step portion, so that the bottom of the injection-molded bottle body 1 covers the step portion of the metal heat conductor 2. Figure 1 As shown, the metal heat conductor 2 and the bottle body 1 are formed into a whole through injection molding.

[0047] Second embodiment:

[0048] See also Figure 2 , the inner cavity of the bottle body 1 is provided with an internal thread. When the connecting part 11 is made of plastic, the metal heat conductor 2 is provided with a connecting part 11 through an injection molding process. The connecting part 11 is provided with an external thread 12. The connecting part 11 of the metal heat conductor 2 is inserted into the inner cavity of the bottle body 1.
