In order to achieve the above purposes and effects, the technical means and structures adopted by the present invention, the features and functions of the present invention are described in detail with reference to the drawings and the preferred embodiments of the present invention so as to fully understand the present invention.

FIGS.1to4show a three-dimensional external view, a three-dimensional exploded view, another three-dimensional exploded view and a side sectional view of the portable brewing and heat preservation device of the present invention. It can be clearly seen from the drawings that the portable brewing and heat preservation device of the present invention includes: a body1, a push-pull assembly2, a top cover3and a bottom cover4, and the detailed structure and connection relationships are as follows:

The body1has a hollow accommodating space10inside, and a first positioning part11and a second positioning part12are respectively arranged on both sides of the body1.

The push-pull assembly2includes a cylindrical bracket21positioned at the inner side of the first positioning part11of the body1; the bracket21has a plurality of liquid channels210; and a push-pull rod22stored in the accommodating space10is penetrated in the center of the bracket21. One end of the push-pull rod22is assembled with a holding block221, and the other end of the push-pull rod22is assembled with a filter-pressing sheet222without any through hole, and a preset gap for liquid circulation is formed between the periphery of the filter-pressing sheet222and the inner wall surface of the body1.

The top cover3is penetrated and assembled on the inner wall surface of the first positioning part11of the body1.

The bottom cover4is penetrated and assembled on the inner wall surface of the second positioning part12of the body1and is internally provided with a holding space40in which a brewed substance5is placed. The brewed substance5refers to tea or ground coffee beans, but the embodiment of the present invention is described with tea, and is not limited to this.

The filter-pressing sheet222is made of ceramic, glass or stainless steel material coated with a ceramic coating, and the range of a preset gap between the periphery of the filter-pressing sheet222and the inner wall surface of the body1is between 0.01 mm and 0.5 mm. The structure of the circular filter-pressing sheet222without any through hole does not build up residue easily and is easier to clean. After the tea (the brewed substance5) and the tea liquor are separated, both cannot communicate through holes or filter screens. Therefore, the release rate of solutes in the tea (the brewed substance5) is effectively slowed down, preventing tea to get any stronger or bitterer, thus more control of the taste. The outer edge of the filter-pressing sheet222is further provided with cotton cloth, nylon cloth or silica gel material with small gaps, so as to provide a better effect for filtering the tea (the brewed substance5). At the same time, the friction between the filter-pressing sheet222and the inner wall surface of the body1can be reduced.

A first internal thread13and a first external thread31that can be screwed mutually are respectively arranged between the first positioning part11of the body1and the top cover3, or positioning ribs (not shown in the drawings) that can engage the first positioning part11of the body1and the top cover3are arranged. A second internal thread14and a second external thread41that can be screwed mutually are respectively arranged between the second positioning part12of the body1and the bottom cover4, or positioning ribs (not shown in the drawings) that can engage the second positioning part12of the body1and the bottom cover4are arranged. The above internal thread, external thread and positioning ribs are all common structural designs for assembling two circular bodies, and should be included within the protection scope of the present invention. In addition, the inner wall surface of the second positioning part12of the body1is further provided with a waterproof gasket15sleeved and positioned on the upper edge of the bottom cover4. The waterproof gasket15can prevent the liquid filled in the accommodating space10from leaking to the outside from the joint between the body1and the bottom cover4.

To assemble the portable brewing and heat preservation device of the present invention, the push-pull rod22of the push-pull assembly2and the bracket21need to be assembled at first, so that the push-pull rod22penetrates through the center of the bracket21and then the push-pull assembly2is fixed to the inner side of the first positioning part11of the body1. At this time, the filter-pressing sheet222on the bottom side of the push-pull rod22is accommodated in the accommodating space10, and the holding block221on the top side of the push-pull rod22protrudes from the outside of the body1. Then, the bottom cover4is fixed at the second positioning part12of the body1in a screwing or clamping manner. The top cover3is also fixed at the first positioning part11of the body1in a screwing or clamping manner, so as to complete the assembly of the portable brewing and heat preservation device of the present invention.

FIGS.5-9show all action diagrams of the operation of the portable brewing and heat preservation device of the present invention. In the actual operation of the portable brewing and heat preservation device of the present invention, after the top cover3is opened at first, the push-pull assembly2should be taken out from the body1; the brewed substance such as the tea is put into the holding space40of the bottom cover4from the first positioning part11of the body1; and then preset hot water or cold water is poured into the holding space40. At this time, the brewed substance5will stretch out in the accommodating space10and the holding space40, and components are released to form a tea liquor. After a preset time is reached, the push-pull assembly2is screwed on the inner side of the first positioning part11, and a force is applied to the holding block221on the top side of the push-pull rod22downward so that the filter-pressing sheet222on the bottom side can press down the stretched tea (the brewed substance5) into the holding space40of the bottom cover4. During the pressing process, the tea liquor continuously flows upward from the preset gap between the periphery of the filter-pressing sheet222and the inner wall surface of the body1to enter the accommodating space10above the filter-pressing sheet222. After the tea (the brewed substance5) is separated from the tea liquor, the user can drink the tea liquor. After several times of brewing, the flavor of the brewed substance5has become weak. At this time, it is necessary to clean the brewed substance5. The specific practice is to remove the bottom cover4at first, so that most of the brewed substance5is removed along with the bottom cover4. At this time, the push-pull rod22is pressed down again to push all the remaining brewed substance5out of the body1, and then the brewing and heat preservation device can be cleaned. Through the above operation, a device with simple operation, convenient carrying and moderate tea taste can be achieved.
