Technical Field

The invention relates to daily supplies, in particular to a plastic thermos bottle plug.

Background

The heat preservation effect of plastics thermos bottle plug is better, but a period of time after the hot water in the bottle is used up, internal pressure diminishes along with the reduction of in-bottle temperature, the atmospheric pressure difference of outer big-end-up will appear inside and outside the thermos bottle, it often is more strenuous when the thermos bottle plug inward filling hot water is expected to take off again, this is that the atmospheric pressure difference leads to, wide thermos bottle plug almost all has such a problem, simultaneously, the thermos bottle after the hot water of just filling also often can appear gathering and the condition of pressure increase because of rising of the thermos bottle plug steam in the short time, then the phenomenon that the pressure differential that leads to because of big-end-up the thermos bottle plug top falls can appear this moment.

Disclosure of Invention

The invention aims to provide a novel technical scheme of a plastic thermos bottle plug, which can solve the disadvantages.

The technical scheme of the invention comprises the following steps: the novel gas plug comprises a plug body and a knob, wherein a round hole, namely an air passage, which penetrates through the plug body from top to bottom is processed in the center of the plug body, and the air passage is continuously extended upwards until the top surface of the knob is below the top surface of the knob; the handle knob is provided with a through hole which penetrates through the vertical wall of the handle knob along the radial direction and the transverse direction to form a slideway, a rod-shaped object, namely a pull rod, the two ends of which are exposed out of the slideway is arranged in the slideway in a penetrating way, the pull rod is connected with the pull rod in a T shape, the pull rod extends downwards into the lower part of the air flue, the middle section of the pull rod is provided with a boss, the upper part of the connecting rod is sleeved with a spring in a penetrating way, the upper end of the spring is embedded and connected onto the inner wall of the air flue, and; the lower end of the connecting rod is connected with a spherical ball head with the diameter smaller than that of the air passage, the air passage below the ball head is processed into a beam diameter, namely the thickness of the lower part of the air passage is reduced, and meanwhile, the pipe wall of the air passage at the diameter-reducing part is processed into a curved surface matched with the spherical surface of the ball head; when the air pressure below the thermos bottle plug in the thermos bottle is large, the pressure of air can upwards jack the bulb in the air passage, the airtight state of the air passage is relieved, a part of air is discharged to avoid the whole thermos bottle plug to be jacked, when the air pressure below the thermos bottle plug is small, when the operation of outwards taking down the thermos bottle plug is carried out, a finger can firstly grab a handle pinching part and incidentally lift the pull rod along the slide way, the pull rod drives the connecting rod and the bulb below the connecting rod to lift up to relieve the airtight state, the air inside and outside the thermos bottle exchanges pressure difference through the air passage to be balanced, and the thermos bottle plug can be easily taken down.

The invention has the beneficial effects that: it can easily take off the thermos bottle plug and can release high-pressure gas to prevent the thermos bottle plug from falling.

Drawings

Fig. 1 is a sectional elevation view of the thermos stopper of the present design (the main view shows the air passage in a sealed condition and the upper view shows the unsealed condition).

In the figure, 1 is a plug body, 2 is a knob, 3 is an air passage, 4 is a ball head, 5 is a connecting rod, 6 is a spring, 7 is a pull rod, and 8 is a slideway.

Detailed Description

The design is illustrated below with reference to the accompanying drawings.

As shown in the figure, the thermos bottle stopper comprises a stopper body 1 and a knob 2, wherein a round hole (namely an air passage 3) which penetrates through the stopper body 1 from top to bottom is processed in the center of the stopper body, and the air passage 3 continues to extend upwards until the position below the top surface of the knob 2; the handle knob 2 is provided with a through hole which penetrates through the vertical wall of the handle knob along the radial direction and the transverse direction to form a slide way 8, a rod-shaped object with two ends exposing out of the slide way, namely a pull rod 7, penetrates through the slide way 8, a connecting rod 5 which is connected with the pull rod 7 in a T shape and extends downwards to the lower part of the air passage and is provided with a boss at the middle section is connected with the pull rod 5, a spring 6 penetrates through the upper part of the connecting rod, the upper end of the spring is embedded on the inner wall of the air passage 3, and the lower end of the spring is elastically tensioned and clamped on; the lower end of the connecting rod 5 is connected with a spherical ball head 4 with the diameter smaller than that of the air passage, the air passage below the ball head 4 is processed into a beam diameter, namely the thickness of the lower part of the air passage 3 is thinned, and meanwhile, the wall of the air passage at the diameter-variable part is processed into a curved surface matched with the spherical surface of the ball head, so that the joint surface at the position can realize the sealing effect under the tensioning action of a spring; when the air pressure below the thermos bottle plug in the thermos bottle is large, the pressure of the air can push the bulb 4 in the air passage upwards to release the closed state of the air passage, and a part of high-pressure hot air is released from the slide way 8 from bottom to top along the air passage to prevent the whole thermos bottle plug from being pushed down; when the air pressure below the thermos bottle plug is small, when the thermos bottle plug is taken down outwards, the fingers can firstly grab the side wall part of the knob 2 and incidentally lift the pull rod 7 along the slide way, at the moment, the pull rod 7 can drive the connecting rod and the ball head below the connecting rod to lift up to remove the sealing state, the air inside and outside the thermos bottle can be fully exchanged through the air passage, the pressure difference inside and outside the thermos bottle can be balanced, and the thermos bottle plug can be easily taken down.
