Technical Field

The utility model belongs to the technical field of domestic appliance, concretely relates to disposable replacement thermos inner bag.

Background

The electric kettle is an electric appliance commonly used in life, the common electric kettle on the market comprises a tank body and a base, the base is connected with a power supply, a heating source is arranged at the bottom of the tank body, and the tank body is fixed on the base so that the heating source at the bottom of the tank body is powered on to heat liquid in the tank body.

The common self-used electric kettle is only used for heating drinking water and has single use. Meanwhile, the electric heating kettle is also provided in the hotel guest room, and although the electric heating kettle is only used as a container for heating drinking water, due to different living habits of different customers, practitioners in the hotel industry often find that many customers do things other than heating drinking water by using the electric heating kettle, and even cook other articles which do not belong to food, such as socks, underwear and the like. Although not every customer has the above-described behavior, most of the checked-in customers have a certain inherent impression due to the public facilities, resulting in the hot water kettle in the hotel not being used or being used to cook other items not belonging to the food.

Due to the above circumstances, the utilization rate of the hot water kettle in the hotel is low, and even if the shopkeeper emphasizes that the shopkeeper has been subjected to strict disinfection measures, the trust level of the client is difficult to establish. Generally, most articles in hotels are disposable products, most customers prefer to accept disposable articles with better quality, and the situation that disposable heating equipment is provided for the customers in the prior art exists. However, due to the particularity of the electric heating structure, it is required to have a relatively strict safety protection module, and the cost of the disposable electric heating device is relatively high.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical scheme that prior art does not have a disposable electric kettle heating, the utility model provides a disposable electric kettle inner bag can be applicable to present most of electric kettle through the inner bag structure that sets up the general type to thereby let the customer feel relieved more through the contact of isolation water with the electric kettle inner wall.

The utility model discloses the technical scheme who adopts does:

a disposable inner container of a replaceable hot water kettle is used for being placed in an electric kettle to heat water and the inner wall of the electric kettle in an isolation state, and comprises:

the inner container body is made of a soft heat-resistant water-proof material and is provided with a fixed opening, enters from the opening of the electric kettle and expands in the inner cavity of the electric kettle to be attached to the inner wall of the electric kettle; and

the heat conducting part is arranged on the liner body and is attached to a heating area at the bottom of the electric kettle for heat conduction after the electric kettle is placed in the liner body.

Firstly, the utility model discloses a mode through providing a disposable inner bag is solved and is had the scheme of unclean or the worry that solves the customer existence when current electric kettle used repeatedly, compares in disposable heating equipment, can utilize the heating effect and the inner chamber space of electric kettle itself, and exists ripe heating components and parts in electric kettle, has higher security, and easy and simple to handle.

The inner container body is made of soft heat-resistant water-proof material, generally adopts silicone oil paper, and the heat-conducting material frequently used in barbecue has better heat-resistant performance, and the maximum resistant temperature is generally within the range of 200-400 ℃.

The silicone oil paper has a three-layer structure, wherein the first layer of base paper is coated, the second layer of base paper is coated, and the third layer of silicone oil is coated. Because the silicone oil paper has the characteristics of high temperature resistance, moisture resistance and oil resistance, the silicone oil paper is generally used for packaging in the food industry.

And the normal temperature range of the heating part in the electric kettle is 100-120 ℃ when the heating part is heated, so that the silicone oil paper can completely resist the temperature.

And because the silicone oil of coating makes this product have better water proof performance, makes it difficult damaged through setting up suitable thickness, pours into inside back with water from the opening, and whole inner bag body can receive the gravity action line of water to expand down, and when not receiving sharp-pointed object fish tail, its own has higher stability.

The heat conducting part is a structure which is arranged for enhancing the heat conducting efficiency between the water in the inner container body and the electric heating kettle, and because the heating part of the electric heating kettle is mostly arranged at the lower part and is usually a circular plane, when the electric heating kettle is used for boiling water, part of water in contact with the bottom is heated to a boiling state and then moves upwards, and the water with lower temperature sinks and contacts with the bottom, thereby forming a heating state of turning up and down until a certain amount of water vapor generated on the water surface is guided into the heating structure at the bottom to heat, separate and power off the metal sheet in the heating structure to complete the heating process.

When the inner container body extends into the electric kettle, the inner container body is firstly expanded downwards by hands, so that the heat conducting part is in fit contact with the bottom in the electric kettle, and then the rest inner container body is expanded towards the periphery and is fit on the vertical inner wall of the inner container body. Because the heat conducting part is completely attached to the bottom, the heat productivity of the electric kettle can be rapidly conducted into the inner container body, and a uniform heating effect is achieved.

It is worth to be noted that the heat conducting portion is arranged only for improving the heat conducting efficiency, and since the thickness of the silicone oil paper adopted by the heat conducting portion is relatively low and the silicone oil has a certain heat conducting effect, the bottom of the heat conducting portion only needs to be completely covered on the bottom surface of the electric kettle as far as possible.

Further, the height of the liner body when the liner body is completely unfolded is larger than the height of the inner cavity of the electric kettle;

when the inner container body is put into the electric kettle, the opening of the inner container body is left outside the electric kettle.

The inner container body is of an integrated structure made of single-layer or multi-layer films, and can be folded to form a small containing volume due to the adoption of soft materials. When in use, the package is torn open and is pre-unfolded to form a columnar structure, and then the columnar structure is stretched into the electric kettle and is completely unfolded to fit the inner wall.

When partially or fully deployed, it has only one opening and forms a cavity inside for containing the water to be heated.

However, during operation, the opening of the electric kettle needs to be expanded first and then water is injected inwards, and the electric kettle can be further expanded and attached to the inner wall under the action of the gravity of the water. If the height of whole inner bag body is less than the height of kettle mouth, then water can drag the opening of inner bag body downwards and make it get into the electric kettle completely, not only probably can not separate water and electric kettle inner wall contact completely, also can not directly take out the inner bag body simultaneously and outwards pour out hot water.

The height of the inner container is higher than that of the inner cavity of the whole electric kettle, so that the opening of the inner container can be kept at the upper part of the opening of the electric kettle even if water is injected into the inner container body.

At the moment, the inner wall of the electric kettle provides a supporting effect for the injected water, and the inner container body keeps a fixed state after the electric kettle is stabilized.

And the inner container body has better water repellency, so that the structural stability of the inner container body is prevented from being influenced by infiltration when water is contacted, and the silicon oil layer enables the paper to have certain plasticity, so that the paper can be kept stable when no external force is received at the part without water.

Simultaneously, because be soft thin layer structure, then can not cause great hindrance to the top cap lock of electric kettle to can carry out whole inner bag body after accomplishing the heating process through dragging the part that exposes the electric kettle, or directly outwards pour out after compressing tightly its opening can.

Furthermore, the inner container further comprises a mouth restraining part which is an annular structure arranged at the opening of the inner container body.

Furthermore, the opening edge of the inner container inner body is embedded into the binding opening part, the binding opening part is also provided with a groove, and the binding opening part is embedded in the opening of the electric kettle for fixing.

The groove is used for clamping the groove part on the edge of the opening when the binding opening part is nested on the opening of the electric kettle, so that a limiting effect is formed.

Furthermore, the opening edge of the inner container body is nested on the mouth restraining part, and at least two hanging lugs used for hanging on the opening edge of the electric kettle are arranged on the mouth restraining part.

The opening height position of the liner body is different from that of the whole annular structure, and the whole annular binding opening part is arranged outside the opening of the electric kettle and is embedded or hung on the edge of the opening for fixing. The hanging lugs are arranged in a manner that the opening of the inner container body is arranged in the electric kettle, and then a plurality of hanging lugs are upwards extended to be hung on the edge of the opening of the electric kettle for limiting.

The mode that adopts the hangers can be better be applicable to the electric kettle of polytypic, because different electric kettles have different opening structure and top cap structure, then can enough fix through a plurality of hangers, can dodge some parts again simultaneously, for example the pivot to accomplish the minimum to the closed hindrance of top cap.

It is worth explaining that the hangers are made of edible stainless steel materials and generally adopt metal sheets with certain shaping capacity, and can be conveniently bent, so that the hangers can be better hung according to the shape of the edge of an opening of the electric kettle, and meanwhile, the hangers can be bent when the top cover is buckled.

Further, the heat conducting part and the inner container body are integrally formed.

Further, the heat conducting part is a metal disc arranged at the bottom of the inner container body when the inner container body is completely unfolded, and the inner container body is directly nested in the metal disc or is fixedly connected with the metal disc through heat-resistant viscose glue.

The metal disc is made of soft bendable thin sheet materials and is only used for increasing the heat conduction efficiency.

Further, the heat conduction part is a metal mesh grid arranged at the bottom of the inner container body when the inner container body is completely unfolded, and the metal mesh grid is fixedly connected with the inner container body through heat-resistant viscose glue.

Example 1:

the embodiment mainly relates to a disposable inner container structure of a hot water kettle.

The existing electric kettle (mainly exemplified by a structure adopting an electric heating mode to heat liquid in the embodiment, and is suitable for all container structures with heated liquid) mostly adopts a split structure design, and comprises a base and a kettle body, wherein a heating structure is arranged in the bottom of the kettle body, the base is used for connecting an external power supply, and the base supplies power to the heating structure of the kettle body through a special plug-in conductive mode.

The kettle body is provided with a switch button for controlling the heating structure to be switched on and off.

The kettle body is made of double-layer stainless steel materials, and heat-resistant plastics are sleeved outside the kettle body to wrap the kettle body. The upper part of the bracket is provided with an opening, and a top cover is rotatably connected at the opening for fixing.

The steam channel is integrated in the top cover of the existing electric kettle, and the steam channel guides the generated steam into the area provided with the heating structure, and two metal sheets 4 are arranged in the area. The metal sheet 4 is deformed after being heated, so that the trip and the circuit break are realized to complete the heating process.

The principle of the thermal trip structure is similar to that of the existing circuit breaker, and after the steam quantity and the temperature reach certain threshold values, the deformation quantity of the metal sheet is enough to form a circuit break, which indicates that the water in the kettle body is heated to the target temperature.

The above-mentioned contents are to explain the structure and heating principle of the existing electric kettle, and the embodiment discloses a disposable liner structure specially arranged in the electric kettle, as shown in fig. 1-3.

The figure shows an electric kettle structure with a top cover, and an inner container body 1 is sleeved inside the electric kettle structure. The inner container body 1 is of a single-layer or double-layer silicone oil paper structure, has good heat resistance and water repellency, and can keep good water insulation rate and structural stability in a high-temperature environment.

The disposable liner structure is mainly used in a plurality of hotels or public places, and as part of customers in the scene have greater resistance to repeated use of the electric kettle, the requirement of water boiling can be met through the disposable liner structure, and water and the electric kettle can be completely isolated in the heating process.

The liner body 1 in this embodiment has a circular opening, and a mouth-tying portion 2 is provided at the opening for restricting the circular opening to be stable.

The bottom of the inner container body 1 is provided with a heat conducting part which is directly contacted with the bottom in the electric kettle, so that the heat at the bottom is rapidly transferred to the water at the bottom of the inner container body 1 as much as possible by increasing the heat exchange efficiency, and the original form of up-and-down circular heating in the electric kettle can be achieved.

The scheme disclosed by the embodiment can be directly arranged in the prior art, namely, the inner container body 1 made of silicone oil paper has a foldable characteristic, so that the volume of the inner container body is variable, and the inner container body can adapt to electric kettle structures with different sizes and shapes.

Meanwhile, because the heating structures of the existing electric kettle are arranged at the bottom, heat can be transferred to the injected water as far as possible through the heat conducting part arranged at the bottom of the existing electric kettle, and a heating circulation effect of turning up and down is formed.

Example 2:

the embodiment discloses a disposable thermos liner, the main structure of which is also a liner body 1 made of silicone oil paper, the liner body 1 has an opening, and the opening is used as the top end to form a cylinder-like structure when the liner body is completely unfolded.

The opening of the liner body 1 is provided with a circular ring-shaped mouth part 2, and the mouth part 2 is a metal ring which has better flexibility and can be conveniently shaped. The inner container body 1 is nested on the mouth restricting part 2 by folding, and can be fixedly connected by adopting a mode of viscose or suture.

As can be seen in figure 2, the radius of the whole beam opening part 2 is larger than the opening radius of the electric kettle, so that the beam opening part is exposed outside, and the opening of the liner body 1 is turned outwards to form a structure nested at the opening of the electric kettle.

Because the binding opening part 2 has certain flexibility, the binding opening part can be adjusted according to different opening sizes, and is generally larger than the opening of the existing electric kettle, and the binding opening part needs to be stuck to the outer wall of the opening of the electric kettle as far as possible in a folding or bending mode, so that a better fixing effect is formed.

Although the top cover is connected with the electric kettle in a sealing way, the inner container body 1 is fixed at the opening of the electric kettle in an outward turning way and has a thinner thickness, so that the top cover can be directly buckled at the opening of the electric kettle without causing great influence on the electric kettle.

The binding opening part 2 in the embodiment can limit and fix the upper end of the whole inner container body 1, so that the condition that the opening of the inner container body 1 sinks into an electric kettle due to the characteristics of the adopted soft material when water is injected or heated is prevented, and the injected water below the water level is prevented from contacting with the inner wall.

In actual operation, although the silicone oil paper has certain plasticity, the silicone oil paper can keep stable when not receiving the action of external force. However, in the steaming process, water is continuously boiled in the inner container body 1, so that the inner container body may be influenced by vibration to cause the above situation, and the mouth-tying portion 2 can better solve the above problems.

Example 3:

the embodiment discloses a disposable inner container of a hot water kettle, which is shown in figures 4 and 5, wherein the matching relationship between the inner container and the hot water kettle is shown.

Specifically, the electric kettle comprises an inner container body 1 and a binding opening part 2 for mounting the inner container body on a bottle opening of the electric kettle.

The inner container body 1 is made of soft heat-resistant waterproof materials, belongs to food-grade products and particularly is silicone oil paper or a multilayer composite material. The multilayer composite material adopts the materials including tin foil paper, silicone oil paper and food-grade glass fiber cloth. This kind of multilayer combined material can adopt the tin foil paper to wrap up in the bottom to be equipped with glass fiber cloth at its inboard or outside and carry out the structure and strengthen, thereby form the heat-conducting part that has higher heat conduction efficiency at 1 bottoms of whole inner bag body.

Because the electric kettle in the embodiment also adopts a bottom heating mode, the tin foil paper layer completely covers the bottom surface of the electric kettle to conduct heat, and the heat consumption can be reduced as far as possible.

Fig. 5 shows a structure of a mouth portion 2 arranged at an opening of the liner body 1, wherein the mouth portion 2 is an annular metal piece, and three hanging lugs 3 are arranged on the metal piece.

The hanging lug 3 is a metal sheet structure with an S-shaped section, one end of the hanging lug is fixedly connected with the binding opening part 2, and the other end of the hanging lug is hung on the opening end face of the electric kettle. The opening of the inner container body 1 in the embodiment is completely sunk into the electric kettle when the inner container body is installed in the electric kettle, but the water level injected into the inner container body is lower than the opening plane of the inner container body 1.

This kind of fixed mode compares in complete cyclic annular fastener structure, can dodge its part of electric kettle originally to the lock of top cap is convenient for.

The top cap of current electric kettle rotates with the kettle body to be connected, then can have certain occupy-place in pivot department, and whole annular fixed knot constructs can form the extrusion portion here, can cause the influence to the lock effect of top cap. The multipoint hanging lug 3 structure can effectively avoid the connecting part and the water outlet, and is fixedly connected with the internal binding opening part 2 to form a better fixing effect.

As can be seen in figure 10, the opening of the liner body 1 is folded outwards and wraps the tying part 2, and then heat-resistant food-grade glue is coated on the connecting part to form a stable connecting relation.

Example 4:

the embodiment discloses a disposable thermos liner, the main structure of which is also a liner body 1 made of silicone oil paper, the liner body 1 has an opening, and the opening is used as the top end to form a cylinder-like structure when the liner body is completely unfolded. The opening of the liner body 1 is provided with a circular ring-shaped mouth part 2, and the mouth part 2 is a metal ring which has better flexibility and can be conveniently shaped. The inner container body 1 is nested on the mouth restricting part 2 by folding, and can be fixedly connected by adopting a mode of viscose or suture.

The lower part of the inner container body 1 in the embodiment is provided with a metal disc 5, and the metal disc 5 replaces the original silicon oil paper layer to directly heat the water injected into the inner container body 1.

As can be seen in fig. 6, the metal plate 5 projects outwards and forms a joint connection with the silicone paper at the edge. The silicone oil paper of the present embodiment differs from the above-described embodiments in that it has two openings, wherein the opening at the top is provided with a constricted portion 2 and the lower opening is covered by a metal disc 5.

The inside border department of metal disc 5 is equipped with the recess, through embedding the opening border of silicone oil paper in this recess and the centre gripping of buckling to have better connection stability. Meanwhile, food-grade heat-resistant glue is coated at the bending part to improve the sealing effect.

During actual test, the food-grade heat-resistant glue is silica gel water, is a two-component semitransparent body, is heated and quickly cured, and has no peculiar smell. Can resist high temperature of more than two hundred degrees, and has mature application on glass hot water kettles and glass health preserving kettles.

Thereby directly laminating the contact through metal disc 5 and the interior bottom of electric kettle directly has better heat transfer effect, and the direct contact heat transfer with the water that pours into inner bag body 1 into is also direct to its inside simultaneously, can reduce the heat loss.

It should be noted that, in order to be suitable for electric kettles of different sizes, the metal plate 5 is also designed to have a smaller thickness and a certain bending performance, but unlike tin foil paper, the metal plate cannot have a higher bending degree of freedom, and the area size of the metal plate needs to be controlled and is generally smaller than the area of the bottom surface.

Example 5:

As shown in fig. 7-10, the liner body 1 in a fully expanded state is shown separately in the figures, and it can be seen that the bottom of the liner body is provided with a metal net 6, the structure is composed of a plurality of concentric metal rings and a plurality of metal strips perpendicular to the concentric metal rings, and the structures are all adhered to the bottom surface of the liner body 1 through food-grade heat-resistant silica gel water.

The metal mesh 6 structure forms a heat conducting part of the inner container body 1, and conducts heat through direct contact with the inner bottom of the electric kettle. Different from the structure of the metal sheet body 4 or the metal disc 5, the structure has a certain heat conduction area and better bending property, and can greatly reduce the sectional area so as to be convenient for being inserted into electric kettles of different sizes.

Example 6:

As shown in fig. 11, similarly to the structure of the above embodiment 5, a plurality of metal sheet bodies 4 are uniformly arranged at the bottom of the liner body 1, and a heat conducting matrix is formed by the plurality of metal sheet bodies 4.

The same as the embodiment 5, the electric kettle has better bending property, and can greatly change the surface shape, thereby being suitable for various electric kettles with different bottom sizes and shapes.
