Technical Field
[0001] The utility model relates to the technical field of daily necessities, in particular to an intelligent constant temperature bowl with multiple heat preservation functions. Background Art
[0002] A constant temperature bowl, also known as a heat preservation bowl, is a tableware that keeps food at a desired temperature. A constant temperature bowl consists of an electric heating plate, a bowl holder, a stainless steel small bowl, a sealed bowl cover and a heat preservation cover. In recent years, with the continuous improvement of people's living standards, constant temperature bowls have developed from ordinary water heat preservation to three types: electrically heated constant temperature bowls and multifunctional constant temperature bowls. Multifunctional constant temperature bowls have also extended to intelligent constant temperature bowls, also called intelligent heat preservation bowls, that is, on the premise of originally having a constant temperature function, high-temperature warning, tipping protection and automatic start functions are added.

[0004] For the above-mentioned prior art constant temperature bowls, they all have a single inner liner, and the heating mechanism is placed between the inner liner and the outer bowl. Although the heating effect is good, the heat preservation effect of the food in the bowl is poor. Summary of the Utility Model
[0005] In order to overcome the deficiencies of the prior art, the utility model provides an intelligent constant temperature bowl with multiple heat preservation functions, which has a simple structure and two inner liners that can both hold food.

[0024] Wherein, there are a bowl body 1, an installation cavity 11, a fixing ring 2, a first inner liner 3, a flanging 31, a heat insulation layer 32, a second inner liner 4, a heating mechanism 5, a sealing ring 6, a bowl cover 7, an outer cover 71, an inner cover 72, a silica gel plug 8, a cut 81, a wavy structure 82, and a power supply 9. Specific embodiments
[0025] In combination with the attached drawings, a further description is given to an intelligent constant temperature bowl with multiple heat insulations provided by the present utility model.
[0026] Example 1, as Figures 1-5 shown, an intelligent constant temperature bowl with multiple heat insulations includes a bowl body 1 and an inner liner arranged inside the bowl body 1. The inner liner is arranged inside the bowl body 1 through a fixing ring 2. Among them, the fixing ring 2 is made of plastic.
[0027] Specifically, the inner liner includes a first inner liner 3 and a second inner liner 4. A heating mechanism 5 is arranged on the first inner liner 3. A gap is left between the first inner liner 3 and the second inner liner 4 to form a heat insulation layer 32. The heat insulation layer 32 is filled with air, and heat insulation is carried out through the air layer.
[0028] Furthermore, a sealing ring 6 is arranged between the upper edges of the first inner liner 3 and the second inner liner 4, so as to further improve the heat insulation effect.
[0029] Furthermore, the second inner liner can be made of materials such as stainless steel and PPSU.
[0030] Furthermore, the heating mechanism 5 is arranged on the bottom surface and side surface of the first inner liner 3, so that the heat transfer of the heating mechanism 5 is faster and more uniform, and it will not be heated only from the bottom of the bowl from bottom to top.
[0031] Furthermore, the heating mechanism 5 can be a heating film, or a heating coating, or a ceramic heating sheet, or a combination of a heating film and a heating coating, or a combination of a heating film and a ceramic heating sheet, etc. It only needs to realize the heating of the first inner liner 3. Among them, the heating film, etc. are prior arts and will not be elaborated here.
[0032] Furthermore, the first inner liner 3 is made of stainless steel material. It can not only serve as a heat conduction transfer component, but also transfer heat to the second inner liner through the stainless steel body. And due to the safety of the stainless steel material, the first inner liner 3 can be used directly.
[0033] Furthermore, the upper mouth edge of the first inner liner 3 is provided with a turned-out flange 31, and the first inner liner 3 is made of stainless steel material.
[0034] Furthermore, the fixation between the first inner liner 3 and the fixing ring 2 can be achieved by the following processes without setting a support piece at the bottom of the bowl:
[0035] Firstly, the flange 31 can be strongly buckled on the fixing ring 2 by a cylinder pressing process to be connected with the fixing ring 2. Secondly, the flange 31 and the fixing ring 2 can be connected by an adhesive process. Thirdly, the flange 31 and the fixing ring 2 can be melted and integrated by a hot melting process.
[0036] Furthermore, a bowl cover 7 can be detachably covered on the bowl body 1, and a ventilation valve is provided on the bowl cover 7, and a silica gel plug 8 is arranged inside the ventilation valve.
[0037] Furthermore, the silica gel plug 8 is provided with a cut 81, and the cut can be a linear cut or a cross-shaped cut. The bottom surface of the silica gel plug 8 is a wavy structure 82, so that the valve surface has a certain supporting force and is not easy to deform. When the food in the bowl has a high temperature and the air pressure in the bowl is large, air can be exhausted through the cut to achieve the effect of stable air pressure. At the same time, due to the self-adhesive property of the silica gel material of the silica gel plug 8, when the air pressure in the bowl is the same as the atmospheric pressure outside the bowl, the cut will recover automatically to achieve a closed effect.
[0038] Furthermore, the bowl cover 7 includes a connected outer cover 71 and an inner cover 72, and a gap is left between the outer cover 71 and the inner cover 72 to form a vacuum layer. Through the design of the double-layer upper cover, the effect of 360° surrounding three-dimensional double-layer heat preservation can be achieved. At the same time, through ultrasonic technology or encapsulation technology, a vacuum layer is designed between the outer cover 71 and the inner cover 72, which is more conducive to the heat preservation of the overall bowl.
[0039] Furthermore, a gap is left between the bowl body 1 and the first inner liner 3 to form an installation cavity 11. A circuit board and a power source 9 are arranged in the installation cavity 11, and the heating mechanism 5 is electrically connected to the circuit board through a wire. The installation cavity 8 itself is also an air layer, which can not only conduct heat preservation, but also leave a certain space between the electronic components and the heating element. While serving as a heat preservation layer surrounding the bottom of the bowl three-dimensionally, it is also beneficial to reduce the heat dissipation of the first inner liner 3 and save the battery at the same time. Among them, the power source 9 can be a lithium battery, a single conventional battery or a rechargeable battery, etc., as long as it can provide power for the heating mechanism 5.
[0040] Embodiment 2: The first inner liner 3 and the second inner liner 4 are in contact and overlapped inside the bowl body 1, and heat transfer is carried out through wall-to-wall contact. The others are the same as those in Embodiment 1.
[0041] Embodiment 3: A gap is left between the first inner liner 3 and the second inner liner 4 to form a heat insulation layer, and the heat insulation layer is filled with water to form a water bath principle for heat preservation. The others are the same as those in Embodiment 1.
[0042] Embodiment 4: The heating mechanism 5 is only provided on the bottom surface of the first inner liner 3. The others are the same as those in Embodiment 1.
[0043] Embodiment 5: The heating mechanism 5 is only provided on the side surface of the first inner liner 3. The others are the same as those in Embodiment 1.
[0044] The present utility model has been illustrated and described by referring to the preferred embodiments. However, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
