Description

Heat preservation device

Technical Field

The invention relates to the technical field of daily necessities, in particular to a heat preservation device.

Background

In cold seasons, due to low air temperature; when food is exposed to air, the temperature drops more rapidly. For infants, the overall eating time is long; therefore, the problem that the appetite of the people is influenced due to the excessively low temperature of the food exists, and the gastrointestinal function of the people can be influenced after the people eat the food for a long time.

Furthermore, for numerous office workers; lunch is usually solved by taking the lunch with the lunch box. The problem that comes with is how to keep the temperature. Therefore, a plurality of optional heat preservation lunch boxes are available to solve the problem of food heat preservation.

The existing heat preservation lunch boxes and the like have various modes such as hot water heat preservation, vacuum isolation heat preservation, heating material heat preservation and the like. For the hot water heat preservation structure, the following are typical: 1. the Chinese patent application with publication numbers CN104586014A and CN105768453A adopts a double-layer box body, and hot water is injected between the double layers of the box body through a water injection port for heat preservation. 2. In the Chinese patent application with publication number CN108851447A, a heating box structure is arranged at the bottom of a lunch box; the heating box is connected with the lunch box through threads.

In the first structure, there is a problem that the water is not smoothly supplied or easily spills out to scald the hand due to the restriction of the size of the water supply port. After the water in the double-layer structure is cooled, pouring out the water if necessary; there is also a problem that it is difficult to completely pour out. In addition, the interior of the double-layer structure cannot be cleaned.

With the second structure, although the defects caused by the water injection port do not exist; however, the sealing performance is difficult to guarantee due to the threaded connection; the requirements for manufacturing are also high.

The two structures also have the problems of universality and the like; the heat preservation structure can not be adapted to different food containers. When the heat preservation is not needed, the integrated design of the heat preservation structure makes the heat preservation structure redundant. In addition, the infant is not convenient to use independently.

The invention is described in detail below with reference to the accompanying drawings:

FIG. 1 is a front cross-sectional view of the present invention;

fig. 2 is a schematic top view of the present invention.

Detailed Description

The embodiments described below are preferred specific examples of the present invention, and various limitations that are technically preferable are added thereto. However, this preferred embodiment is not intended to limit the present invention; but equivalent variations can be obtained in accordance with the foregoing description; all fall within the scope of the present invention.

Referring to fig. 1 and 2, the heat preservation device of the invention mainly comprises an encapsulation 1, a sealing ring 2, a gland 3 and a locking piece 4. The shape of the encapsulation 1 is substantially the same as the stainless steel bowl 5 that it needs to keep warm (in the present invention, the stainless steel bowl 5 is one of the containers 5, and the container 5 can be made of other materials with better thermal conductivity). The middle part is approximately planar and the periphery is obliquely upward. After the rubber coating 1 is obliquely upwards provided with a certain depth, the rubber coating horizontally spreads to the periphery to form a horizontal spreading part 11. The starting portion 111 of the horizontal spreading portion 11 horizontally spread all around corresponds to the top edge 51 of the stainless bowl 5. The gasket 2 is provided at a position of the horizontally expanded portion 11 near the starting portion 111. The top edge 51 of the stainless steel bowl 5 can be brought into sealing engagement with the horizontal development 11 by means of the sealing ring 2. The horizontally developed sections 11 continue to expand around, around the top edge 51 and curve upwardly so that the upper surface of a subsequent horizontally developed section 11 is coplanar with the upper surface of the top edge 51. The outer contour of the horizontal development 11 is slightly larger than the outer diameter of the top edge.

When the top edge 51 of the stainless steel bowl 5 is in sealing fit with the horizontal development by the sealing ring 2, a sealed space 6 is formed between the encapsulation 1 and the stainless steel bowl 5.

The horizontal spreading portion 11 is symmetrically provided with two locking lug parts 112 along the circumference, and the locking lug parts 112 have the functions of realizing a locking structure and holding. The outermost edge of the horizontal expanse 11 may be formed downwardly and inwardly with a barb 113. The gland 3 is substantially in the form of a planar ring; the outer edge of the horizontal expansion part corresponds to the outermost edge of the horizontal expansion part, and a barb 31 can also be formed downwards and inwards. Barbs 31 of gland 3 may hook over barbs 113 of horizontal deployment section 11. The inner edge of the gland 3 corresponds to the top rim 51 of the stainless steel bowl 5 and has a diameter slightly larger than the inner diameter of the top rim 51. The edge 32 of the inner edge of the gland 3 is bent downwards; pressing against the upper surface of the top rim 51 of the stainless steel bowl 5.

The locking lug 112 of the horizontal spreading part 11 can be provided with a locking piece 4, and the horizontal spreading part 11 and the gland 3 are tightly locked together through the locking piece 4. The locking member 4 may be a circular lock. Specifically, a female screw hole is provided at an appropriate position of the locking lug 112, and the gland 3 is provided with a through hole corresponding to the female screw hole. The stud of the circular lock passes through the gland 3 and is screwed with the internal thread hole of the locking lug part 112. The locking cap of the circular lock is pressed against the upper surface of the gland 3. At this point, the edge 32 is pressed against the top edge 51; the lower surface of the top edge 51 is tightly sealed with the upper surface of the horizontal expansion part 11 by the sealing ring 2; the space 6 is sealed. For convenient use, a groove 41 can be arranged at the top of the round lock; the circular lock can be turned by a thin hard object such as a coin. The width of the groove 41 is slightly larger than the thickness of the one-yuan coin, so that the locking piece can be opened and closed only by the one-yuan coin, and children are prevented from opening the locking piece. The part of the gland 3, which is matched with the lock cap of the circular lock, can slightly form a concave matching table surface 33 relative to other parts; in order to prevent the locking cap of the circular lock from protruding too far into the gland 3.

A suction cup 7 can be integrally or detachably connected to the bottom of the encapsulation 1.

When in use, the sucker 7 is assembled at the bottom of the rubber coating 1 according to the requirement (in this case, the rubber coating 1 is suitable for being connected with the sucker 7 in a detachable mode; if the rubber coating is integrally formed, the step is omitted); then, a proper amount of hot water is introduced into the encapsulation 1; the hot water quantity and the hot water temperature can be adjusted according to actual needs, but the hot water quantity cannot be higher than the maximum scale marking line in the rubber coating 1. The sealing ring 2 is placed on the horizontal development 11 of the casing 1, and the sealing ring 2 is placed so that the inner side of the sealing ring 2 is generally in a relatively uniform position with respect to the initial part 111 of the horizontal development 11. In order to facilitate the positioning of the sealing ring 2, two positioning rings are convexly extended on the upper surface of the horizontal unfolding part 11; the sealing ring 2 is arranged between the positioning rings to realize convenient and accurate positioning.

After the above steps are completed, the stainless steel bowl 5 containing food (or the stainless steel bowl 5 can contain food after all the preparation steps before use are completed and the encapsulation 1 and the stainless steel bowl 5 are sealed and fixedly matched according to the preference of a user) is placed on the encapsulation 1. When the hot water bag is placed, the action is gentle, and hot water is prevented from being wrapped outside the bag 1 or being scalded. The placement position needs to be careful not to expose the seal ring 2 outside the top edge 51 of the stainless steel bowl 5.

Then the gland 3 is arranged on the rubber coating 1, and the orientation of the gland 3 is noticed during the arrangement; it is necessary to have the bent portions of the barbs 31 and the edges 32 face downward. And the barb 31 of the gland 3 is hooked with the barb 113 of the horizontal expanded portion 11. The gland 3 is then locked with the overmold 1 using the latches 4. Thus, the stainless steel bowl 5 and the rubber coating 1 are in sealing combination through the sealing ring 2; hot water seepage is avoided.

After the above assembly is completed, the hot water in the space 6 between the encapsulation 1 and the stainless steel bowl 5 conducts heat to the food through the heat conducting stainless steel material, thereby avoiding the food temperature from decreasing too fast. The material of the encapsulation 1 is rubber and other materials with slow heat conduction; thus, heat will be conducted mainly to the stainless steel bowl 5 of stainless steel material.

In addition, the utility model can be absorbed and fixed on the table top through the sucker 7; is suitable for infants.

After use, the knob locking piece 4 opens the gland 3; the stainless steel bowl 5 can be separated from the encapsulation 1. The stainless steel bowl 5, the rubber coating 1 and other heat preservation components can be cleaned as required.
