Anti-scalding thermos bottle

Technical Field

An anti-scald thermos bottle belongs to the technical field of thermos bottle structures.

Background

Thermos bottles are common hot water storage and containing tools in life. The thermos bottle generally comprises a shell and an inner container, wherein the inner container is generally made of silver-plated glass, and the shell is made of plastic.

When the thermos bottle is heated inequality, the cold and hot difference in temperature is too big, or the base is ageing etc., all lead to the burst of inner bag easily, burst the condition and send out especially many splendid attire hot water in-process or carry the removal process, because there is higher pressure difference, can have the inner bag piece and the hot water condition of splashing when exploding to split the emergence, soften the shell in hot water, under the pressure inflation, the shell can be propped easily and split and explode the bits, the piece splashes and can lead to serious user skin fish tail, and hot water can lead to burning and scalding, be serious bodily injury, and inner bag and shell piece are because of tiny, sharp, difficult processing, also can cause secondary hazard and potential safety hazard.

One of the solutions commonly adopted in the prior art is to adopt a metal shell, but the metal shell has good heat-conducting property and poor heat-insulating property on the one hand, and is heavy on the other hand, high in manufacturing cost, not suitable for being used at home, easy to rust, not corrosion-resistant and not in line with the requirements of use environment.

Detailed Description

The present invention will be further described with reference to the accompanying drawings 1-2.

Example 1

Referring to the attached figures 1-2: an anti-scald thermos bottle comprises a shell 1, a buffer shell 2 and an inner container 3 from outside to inside in sequence.

Buffer shell 2 sets up between inner bag 3 and shell 1, is equipped with 5cm clearance between buffer shell 2 and the shell 1, and shell 1 is hollow cylindric, and the top is equipped with the diameter from bottom to top and reduces gradually compresses tightly portion 6, 6 central opening of portion that compresses tightly, and the opening part is equipped with annular guard shield 7. The shape that the 2 tops of buffering shell correspond to clamping part 6 also is equipped with reducing structure, and reducing structure contact extrusion clamping part 6, reducing structure top central point puts and corresponds the opening, and the opening edge is upwards protruding. The opening outer wall of the reducing structure of the buffer shell 2 is provided with threads, the inner wall of the protective cover 7 of the shell 1 is provided with corresponding threads, and the shell 1 is connected with the buffer shell 2 through threads.

2 lateral walls of buffer shell and bottom all are equipped with a plurality of through-holes, and 2 bottoms of buffer shell still are equipped with buffer base 21 simultaneously, and buffer base 21 bearing inner bag 3 bottoms, 1 bottom of shell are equipped with outer shell base 11, and outer shell base 11 extrusion contact buffer shell 2 bottoms surfaces.

The bottom of shell 1 and buffer shell 2 is connected with respective casing can be dismantled, and the bottom is established connection shell 1 and buffer shell 2 lateral wall through the screw thread is twisted respectively. The top opening of the inner container 3 is provided with a bottle cap. In buffer shell 2 upwards put into shell 1 from 1 bottom opening of shell, buffer shell 2 is upwards put into to inner bag 3 from 2 bottom openings of buffer shell, screws up the bottom of buffer shell 2 and shell 1 in proper order, utilizes the portion of compressing tightly 6 of shell 1 and the fixed buffer shell 2 of bottom extrusion, and then stabilizes inner bag 3.

The shell 1 and the buffer shell 2 are made of PP materials, and the inner container 3 is made of vacuum glass materials.

When this prevent scalding thermos bottle splendid attire hot water, it is uneven to be heated, and the cold and hot difference in temperature is too big, or reasons such as the base is ageing, when the emergence inner bag 3 explodes and splits, buffer shell 2 will cushion first momentary pressure, and thoroughly parcel makes hot water and atmospheric pressure partly can flow away to between shell 1 and buffer shell 2 through the through-hole, and the cracked piece of inner bag 3 will be blockked in buffer shell 2. Because of the buffering effect of buffering shell 2, 3 pieces of inner bag can not direct contact shell 1, avoid sharp piece fish tail or the shell 1 that the striking shell 1 leads to cracked, realized guaranteeing the integrality of shell, improve protectiveness.

The buffer shell 2 with the drainage function is selected instead of simply adding a layer of inner shell, and the proper buffer function is used for replacing the situation that the pressure, the hot water and the fragments of the inner container 3 are completely wrapped, so that the safety performance of the thermos bottle is improved, and the buffer shell 2 is smaller in weight, lighter and lower in manufacturing cost due to the through holes, and better meets the daily use and low-price product attributes of the thermos bottle, thereby achieving multiple purposes; the PP plastic is heat-resistant, has stronger mechanical property, low cost and higher cost performance, is not easy to crack, and can be repeatedly used after the inner container 3 is cracked.

Example 2

Referring to FIG. 3: the utility model provides a prevent scalding thermos bottle, on embodiment 1's basis, simultaneously the bottleneck department at the inner bag sets up photoelectric sensing ware 5, set up alarm lamp 4 in 1 top outside of shell, 5 transmitting probe of photoelectric sensing ware is towards the bottleneck centre of a circle, alarm lamp 4 is connected to photoelectric sensing ware 5, when 3 water-logging of inner bag are full to 5 detection position of photoelectric sensing ware, trigger photoelectric sensing ware 5, light signal turns into the signal of telecommunication and triggers alarm lamp 4, in dark environment, under steam environment or the user wears glasses and has hazed the condition, bright alarm lamp 4 will indicate that water is full, in time close out tap.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
