The technical field is as follows:

the invention relates to the technical field of tea cups, in particular to a self-heating disposable tea cup.

Background art:

the disposable tea cup is a common container in our lives, can be used for containing beverage or liquid, can also realize the brewing of tea, is very convenient for people who love drinking tea, and has low cost and low manufacturing cost; at present, along with the improvement of living standard of people, more and more people can go out to travel or step on green in the field after being idle, the demand for hot water is generally solved by carrying a thermos cup, but the capacity of the thermos cup is certain, after the hot water in the thermos cup is drunk, no hot water exists, and if tea or coffee beverage is wanted to be drunk in the field, the hot water is needed to be infused through a disposable teacup, but the field is relatively remote, and the hot water cannot be supplemented, so that the tea or infused beverage cannot be drunk in the field, although the heatable cup exists in the market at present, the structure of the existing heatable cup is relatively complex, the price is relatively expensive, and the cost for the disposable teacup is relatively high.

The invention content is as follows:

the invention provides a self-heating type disposable tea cup, which can not only self-heat to obtain hot water in the field and other situations without power, but also can brew tea or drinks by the self-heating obtained hot water, and is convenient to use and low in cost.

The technical scheme adopted by the invention for solving the technical problems is as follows: a self-heating disposable teacup comprises a cup body, wherein a sealing layer is arranged at the bottom of the cup body, a filter layer is arranged inside the cup body and fixed with the inner peripheral side wall of the cup body, a heat conduction layer is arranged below the filter layer in a sealing manner and is connected with the inner peripheral side wall of the cup body in a sealing manner, a tea cavity is formed by the filter layer and the heat conduction layer, and a tea bag is placed in the tea cavity; the heat conducting layer and the sealing layer at the bottom of the cup body form a heat source accommodating cavity, a self-heating bag is arranged in the heat source accommodating cavity, a self-heating bag conveying channel is arranged on the inner side of the cup body, and the self-heating bag conveying channel penetrates through the tea leaf cavity and is communicated to the heat source accommodating cavity; a tea conveying channel is also arranged in the cup body and penetrates through the filter layer to be communicated with the tea cavity.

Furthermore, the self-heating bag conveying channel and the tea conveying channel are flush with the cup mouth of the cup body.

Furthermore, the tea leaf conveying device also comprises a sealing plug which is matched with the sealing clamp sleeve in the tea leaf conveying channel and the top end of the tea leaf conveying channel.

Further, the heat conducting layer is made of aluminum foil paper.

Furthermore, the material of the filter layer is a corn fiber membrane.

The invention also provides a preparation process of the self-heating disposable teacup, which is characterized in that the inner cup, the middle cup and the outer cup are fixed together by heat seal or adhesive sleeve to form a composite cup body, the bottom of the inner cup is a filter layer, the bottom of the middle cup is a heat conduction layer, the bottom of the outer cup is a sealing layer, and the height h of the outer cup is₁Height h of TsBg middle cup₂Height h of inner cup₃Thereby forming a tea water cavity positioned at the upper side of the filter layer, a tea cavity positioned between the filter layer and the heat conduction layer and a heat source accommodating cavity positioned between the heat conduction layer and the sealing layer; the side wall of the inner cup is respectively provided with an inwards concave groove A and a concave groove B₁The side wall of the middle layer cup is provided with an inward concave groove B₂After the three layers of cups are combined, B₁And B₂The tea cup is sleeved and fixed together in a matching way, so that a tea conveying channel enclosed by the groove A and the middle cup is formed, and the bottom of the tea conveying channel is communicated with the tea cavity; and form a groove B₂And the bottom of the self-heating bag conveying channel is communicated with the heat source accommodating cavity.

Further, the inner layer cup cylinder is a non-woven fabric cup, the middle layer cup cylinder is an aluminum foil paper cup, and the outer layer cup cylinder is a paper cup.

Furthermore, the wall surface of the non-woven fabric cup of the inner layer is coated with a wax material.

Furthermore, a material conveying pipe is sleeved in the tea conveying channel or the self-heating bag conveying channel in a matching mode and used for supporting all the channels to keep the unfolded shape.

The invention has the beneficial effects that: the present invention has four benefits.

First, simple structure, reasonable in design under the circumstances that does not have hot water, through adding cold water to from hot packet transfer passage, cold water just can flow to heat source and hold the chamber through from hot packet transfer passage, cold water just can send a large amount of heats with from hot packet to accomplish and heat teacup normal water, accomplish the bubble to tealeaves or drink, convenient to use.

Secondly, the inner cup, the middle cup and the outer cup are bonded together by heat seal or adhesion, so that the lime water generated after the water contacts with the self-heating bag in the heat source accommodating cavity can be prevented from leaking out, and the sealing plug arranged at the head end of the heat source accommodating cavity can prevent the lime water after the chemical reaction in the heat source accommodating cavity from possibly flowing out of the self-heating bag conveying channel when the teacup is used.

Thirdly, different tea leaves can be put into the tea conveying channel according to the taste of the user for brewing, so that the tea conveying channel is suitable for drinkers with different tea tastes; when a drinker does not want to drink tea water but hot water, the tea leaves do not need to be put into the tea leaf cavity through the tea leaf conveying channel, the use is flexible, and the situation that the tea water possibly flows out of the tea leaf conveying channel when the drinker uses the tea cup can be prevented through the sealing plug at the head end of the tea leaf conveying channel.

Fourthly, the teacup is convenient to carry, does not occupy space, is made of environment-friendly materials, and does not pollute the environment.
