Description

Technical Field

[0001] This utility model relates to the field of thermos bottle technology, and in particular to a thermos bottle anti-overflow structure. Background Technology

[0002] The main function of a thermos flask is to maintain a stable liquid temperature, unaffected by the external environment. It can keep hot drinks at a certain high temperature, allowing users to enjoy hot water at an ideal temperature for a long time. However, when hot water is filled into the thermos flask, there is a possibility of overflowing and spilling into the outside.

[0003] Chinese patent discloses a method for manufacturing a thermos flask (authorization announcement number CN202086323U). This patented technology mainly consists of a thermos flask cap, a cap insulation layer, a flask shell, an upper insulation layer of the inner liner, a stopper, an inner liner, a lower insulation layer of the inner liner, and a bottom of the flask shell. The thermos flask can be a hot water bottle or a thermos cup. The inner liner can be a glass vacuum liner, a stainless steel vacuum liner, a regular glass liner, or a ceramic liner. This thermos flask features good heat retention and impact resistance; water boiled at 100℃ can maintain its temperature at approximately 92℃ after 24 hours.

[0004] This patented technology has the advantage of good heat preservation during use, but there are still shortcomings. When hot water is filled into the thermos, the water level is difficult to observe due to the small opening of the thermos, and it is easy for the water to overflow and spill into the outside, causing burns or splashing and wetting the table and items. Therefore, those skilled in the art have provided a thermos anti-overflow structure to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an anti-overflow structure for a thermos bottle, comprising:

[0008] The thermos bottle structure includes a bottle body, a bottle mouth located at the upper end of the bottle body, an inner liner located inside the bottle body with its opening in the bottle mouth, a bottom cap threaded to the lower end of the bottle body, and a flared spout located at the upper end of the bottle mouth.

[0009] The anti-overflow structure includes an annular inner cavity formed on the inner wall of the bottle mouth, an annular groove formed on the inner wall of the flared mouth, an overflow hole formed on the inner wall of the annular groove and communicating with the inner cavity and distributed in an annular array, a through-hole formed on the bottle mouth and communicating with the inner cavity, and a sealing plug located inside the through-hole.

[0010] as well as;

[0011] An opening and closing structure, including a stopper located inside the bottle opening.

[0012] Furthermore, a handle is provided at one end of the bottle body, and a pouring spout is provided at one end of the flared mouth.

[0013] Specifically, the handle makes it easy to apply force to move the bottle, and when pouring water, the spout guides the water flow.

[0014] Furthermore, the outer wall of the bottom cover is provided with anti-slip textures arranged in a ring array, and an anti-slip pad is provided at the lower end of the bottom cover, with several through holes at the lower end of the anti-slip pad;

[0015] Specifically, when the bottom cap is rotated, the anti-slip texture increases the friction with the hand. When the bottle is placed, the anti-slip pad improves the adhesion and firmness between the bottom and the table. The through hole, located at the lower end of the protective pad, acts as an adsorption force on the table when the bottle is squeezed.

[0016] Furthermore, the inner wall of the horn mouth is provided with symmetrically distributed support blocks, and a damping sleeve is embedded in the support block. A stopper rod is provided at the upper end of the stopper, and a rotating shaft is provided at both ends of the stopper rod and rotatably installed inside the damping sleeve.

[0017] Specifically, the plunger rotates inside the damping sleeve via a pivot. During rotation, the damping force of the damping sleeve applies resistance to the pivot after rotation, thereby positioning the pivot.

[0018] Furthermore, a frame-shaped lever is provided at the upper end of the rotating shaft, and a flow guide ring is provided at the upper end of the bottle mouth, with the inner diameter of the flow guide ring gradually decreasing from top to bottom;

[0019] Specifically, when rotating the shaft, gripping the lever facilitates applying rotational force to the shaft, and the water poured from the bottle opening is guided directly into the flared mouth through the guide ring, preventing water from entering the ring groove.

[0020] Furthermore, the inner wall at the lower end of the inner cavity is provided with a flow guiding surface, one end of the bottle mouth is provided with an operating groove that communicates with the opening, and one end of the sealing plug is provided with a pull handle located inside the operating groove;

[0021] Specifically, the flow guide is used to guide the activated carbon particles, and the operating groove facilitates the gripping of the handle, which in turn facilitates the application of force to the sealing plug.

[0022] 2. Beneficial effects

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] In this invention, boiling water is poured into the inner liner through the bottle mouth, and the bottle stopper closes the opening of the inner liner, thus sealing the hot beverage after filling and keeping it warm.

[0025] Meanwhile, during the thermoforming filling process, water overflowing from the bottle mouth enters the inner cavity inside the bottle mouth through the overflow hole, preventing hot water from spilling directly to the outside. The desiccant in the inner cavity absorbs the overflowing water, and the desiccant is replaced regularly, making it easy to handle the overflowing water and preventing hot water from spilling directly, thus improving the safety and reliability of the thermos bottle.

[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] Please see Figures 1-7 As shown, this embodiment is a thermos bottle anti-overflow structure, including,

[0045] The thermos bottle structure 100 includes a bottle body 101, a bottle mouth 109 located at the upper end of the bottle body 101, an inner liner 103 located inside the bottle body 101 with its opening located in the bottle mouth 109, a bottom cap 104 threadedly installed to the lower end of the bottle body 101, and a flared spout 111 located at the upper end of the bottle mouth 109.

[0046] The anti-overflow structure 300 includes an annular inner cavity 301 formed on the inner wall of the bottle mouth 109, an annular groove 302 formed on the inner wall of the flared mouth 111, an overflow hole 303 formed on the inner wall of the annular groove 302 and communicating with the inner cavity 301 and distributed in an annular array, a through-hole 307 formed on the bottle mouth 109 and communicating with the inner cavity 301, and a sealing plug 306 located inside the through-hole 307.

[0047] as well as;

[0048] The opening and closing structure 200 includes a stopper 201 located inside the bottle opening 109.

[0049] A handle 102 is provided at one end of the bottle body 101, and a pouring spout 108 is provided at one end of the flared mouth 111;

[0050] The outer wall of the bottom cover 104 is provided with anti-slip textures 107 arranged in a ring array, and an anti-slip pad 105 is provided at the lower end of the bottom cover 104. Several through holes 106 are opened at the lower end of the anti-slip pad 105.

[0051] A flow guide ring 110 is provided at the upper end of the bottle mouth 109, and the inner diameter of the flow guide ring 110 gradually decreases from top to bottom;

[0052] Use of anti-overflow structure 300;

[0053] Hot water is poured into the inner tank 103. When hot water overflows, it enters the ring groove 302 through the guide ring 110 and enters the inner cavity 301 through the overflow hole 303. The desiccant in the inner cavity 301 absorbs the hot water, and the overflowing hot water is intercepted and collected, preventing hot water from spilling to the outside. This avoids the problem of hot water scalding people and wetting items, which could lead to damage to items or people slipping on the wet floor, increasing the risk. Because it is not easy to observe the water level, hot water overflows frequently, and cleaning the overflowing liquid will affect the actual user experience and increase unnecessary trouble.

[0054] Meanwhile, when hot water enters the opening of the inner liner 103 without overflowing, the bottle stopper 201 will be inserted into the opening of the inner liner 103, which will squeeze the water out of the opening. At this time, the overflowing water will also enter the inner groove and overflow hole 303, and then be absorbed by the desiccant. Through the anti-overflow treatment, the risk of liquid overflow and scalding is reduced. It is suitable for families, schools and other places with children, effectively avoiding the risk of hot liquid overflow and scalding, reducing the situation of accidental overflow, and improving the comfort of use.

[0055] After use, squeeze the handle 305 through the operating port to let the sealing plug 306 overflow from the outlet 307, and pour out the desiccant and replace the desiccant.

[0056] Example 2

[0057] Please see Figures 1-7 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0058] The inner wall of the bell mouth 111 is provided with symmetrically distributed support blocks 203. A damping sleeve 204 is embedded in the support block 203. A stopper rod 202 is provided at the upper end of the stopper 201. Both ends of the stopper rod 202 are provided with rotating shafts 206 that are rotatably installed inside the damping sleeve 204.

[0059] A frame-shaped paddle 205 is provided at the upper end of the pivot 206;

[0060] The inner wall at the lower end of the inner cavity 301 is provided with a flow guide surface 308, and one end of the bottle mouth 109 is provided with an operating groove 304 that communicates with the through port 307. One end of the sealing plug 306 is provided with a pull handle 305 located inside the operating groove 304.

[0061] Use of the opening and closing structure 200;

[0062] By gripping the handle 305 and turning the shaft 206, the shaft 206 rotates within the damping sleeve 204 inside the support block 203. During rotation, resistance is applied, and the rotated shaft 206 is positioned. The shaft 206 then drives the stopper rod 202 to rotate, bringing the stopper 201 out of the opening of the inner liner 103 and into the upper part of the spout 111. Water droplets adhering to the stopper 201 are collected by the spout 111 as they drip down, and then flow through the inner wall of the spout 111 into the inner liner. After the water enters the inner cavity 301 through the overflow hole 303, the water droplets are absorbed by the desiccant, preventing the water droplets on the bottle stopper 201 from falling to the outside. When the lever 205 rotates and fits against the inner wall of the horn 111, it limits the rotation shaft 206, so that the bottle stopper 201 is at most located in the space above the horn 111, preventing the bottle stopper 201 from dripping to the outside. During use, the bottle stopper 201 will not be difficult to find due to random placement, and it is less likely to fall to the ground and be contaminated.
