Description
Technical Field
The invention relates to a filter screen cover, in particular to a filter screen cover with a folding bracket.
Background
With the improvement of the consumption level and the life quality of people, the outdoor activities become effective means for reducing fatigue and blood pressure after tea and meals, and the portable drinking water container becomes a necessary choice for supplementing water and nutrition during the outdoor activities of people.
At present, the drinking water container on the market is single in function and only is used for containing liquid, and a filter screen cover can be purchased independently and clamped at the mouth of the container for brewing various brewing products such as self-grinding coffee and tea, but the filter screen cover is arranged in a mode of occupying the space of the drinking water container on one hand, so that drinkable liquid amount is reduced, and on the other hand, tea and the like in the drinking water container are always in a brewing state, or steam in the container is always used for heating the tea, so that the taste of the tea is influenced. In addition, the filter screen cover has a single structure, the size of the filter screen cover is fixed, the filter screen cover can only be matched with the container liner with the same caliber, if a user needs to purchase a filter screen cover which meets the caliber of the container to reassemble when the container is replaced for use, the cost is high, and the improvement is needed.
Disclosure of Invention
Aiming at the defects that the filter screen cover in the prior art is overlarge in occupied space and cannot be matched with container liners with different calibers, beverage brewing taste in a beverage container is poor, and the like, the invention provides a novel filter screen cover with a folding bracket.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the utility model provides a filter screen lid with folding support, includes lid, filter screen piece, form accommodation space in the lid, the filter screen piece set up on the lid and with accommodation space intercommunication, rotate on the lid and be connected with folding support assembly and form accommodation position, supporting position through rotating folding support assembly, under the supporting position, folding support assembly outwards expands and supports the lid, under the accommodation position, folding support assembly inwards contracts and accommodates on the lid.
The lid is used for installing the filter screen piece to form accommodation space in its inside, the user will need filterable drink to dash accommodation space, and the folding supporting component of swivelling joint is used for supporting the lid on the lid to place the filter screen lid on bowl cover or container oral area or other containers that can hold liquid through folding supporting component, and need not to inlay in the cup like general filter screen lid must, thereby can let the use of filter screen lid more freely nimble. In addition, according to the brewing needs of different brewed beverages, the filter screen sheets on the cover body can be detached from the cover body, so that the filter screen sheets with different meshes are replaced to adapt to the filtering needs of various different beverages. When the beverage filter is used, a user can tear the package of the brewing product and pour the brewed beverage such as coffee, tea and the like into the filter screen cover, and the filter screen cover filters filter residues in the beverage, so that the beverage filtered into the container is free from impurities.
According to the invention, impurities in the beverage can be effectively removed through the filtering function of the filter screen cover, and the filter screen cover can be firmly supported on articles such as a cup cover and a cup body through the folding and supporting functions of the folding and supporting components of the filter screen cover, unlike the traditional filter screen cover which is embedded in the cup body, the use freedom of the filter screen cover is greatly improved, a user can select more when using the filter screen cover, and the beverage such as coffee, tea and the like can be well brewed and filtered, so that the daily requirements of people can be well met.
Preferably, the above-mentioned filter screen cover with folding support, folding support assembly includes two at least folding support, rotation circle, the rotation circle rotate connect in on the lid, folding support one end connect in on the lid lateral wall, folding support other end connect in on the rotation circle, be provided with the bending part on the folding support, the rotation circle drives when rotating folding support other end slip and form holding position, supporting position, when folding support is in supporting position, the bending part outwards expands and supports the lid, when folding support is in holding position, the bending part inwards contracts and holds on the lid.
The folding support is used for supporting the cover body on articles such as the cup cover and the cup body when the folding support assembly forms a support position, so that a user can pour the beverage into the cover body for filtering, and the filtered beverage is poured into the articles such as the cup cover and the cup body. One end of the folding bracket is connected with the cover body, and the other end of the folding bracket is connected with the rotating ring, so that a user can drive the folding bracket to switch between the accommodating position and the supporting position only by rotating the rotating ring, and the use convenience is improved.
