Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, specifically a thermos cup that facilitates fixing the filter screen. Background Technology

[0002] To isolate the inside and outside of the cup and prevent the liquid inside from rising or falling rapidly, containers made of ceramic or stainless steel with heat-insulating capabilities are often used, and are called thermos cups. Most of the cups have threads on the top of the cup so that a matching lid can be screwed on.

[0003] To enrich people's lives, many choose to use insulated cups to brew tea and enhance the flavor of drinking water. However, tea leaves float and sink with the tea water and end up in the mouth, making the tea bitter and inedible. Traditional insulated filter screens are directly attached to the cup opening, lacking a limiting and fixing function, making it difficult to ensure the stability of the filter screen. The filter screen is prone to detaching from the cup opening while drinking tea, which is quite inconvenient.

[0004] Now, a new type of thermos cup that facilitates the fixing of the filter screen is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a thermos cup with a filter that is easy to fix, so as to solve the problem mentioned in the background art that the filter is easy to detach from the cup mouth.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermos cup for easy fixing of a filter screen, comprising a cup body, a cup mouth fixed at the top of the cup body, and a metal mesh cover snapped into the inside of the cup mouth; an installation groove is provided above the center of the front end of the inside of the metal mesh cover, and a limiting block is fixed inside the installation groove; a slot is provided below the installation groove, and a second locking block is fixed inside the slot; side grooves are provided inside the two sides of the metal mesh cover, and a first locking block is fixed inside the side grooves; an elastic retaining ring is horizontally snapped into the front of the inside of the metal mesh cover, and protruding rings are provided on both sides of the elastic retaining ring; a concave ring is provided at the center of the elastic retaining ring; a metal ring is fixed around the top of the metal mesh cover; and a positioning ring is provided around the bottom of the inside of the cup mouth.

[0007] As a further technical solution of this utility model, the convex rings are all embedded in the first locking block of the side groove, and the concave rings pass through the limiting block and are embedded in the second locking block.

[0008] As a further technical solution of this utility model, the metal ring is attached to the top of the positioning ring, and the metal ring moves vertically up and down inside the cup mouth along with the metal mesh cover.

[0009] As a further technical solution of this utility model, a bottom plate is horizontally arranged inside the metal mesh cover, and mesh holes are arranged in the bottom plate. A pull ring is welded at the center of the top of the bottom plate.

[0010] As a further technical solution of this utility model, the bottom of the outer side of the cup body is provided with a cup bottom, and the top of the cup bottom is provided with a groove. A protrusion is fixed on the lower surface of the cup body, and a cavity is provided longitudinally inside the cup body.

[0011] As a further technical solution of this utility model, the protrusion is embedded in the groove, and the undulating texture of the protrusion matches the inner wall of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the thermos cup that makes it easy to fix the filter not only prevents the filter from moving and makes it easy to remove the filter, but also thickens the bottom of the cup;

[0013] (1) By horizontally engaging an elastic retaining ring inside the metal mesh cover, the metal mesh cover is inserted into the cup body from the cup mouth by pinching the pull ring. The metal ring at the top of the metal mesh cover overlaps on the positioning ring, which can prevent the metal mesh cover from falling. Then, the elastic retaining ring is engaged in the metal mesh cover. The protruding rings on both sides of the elastic retaining ring are embedded in the first retaining block in the side groove, while the concave ring at the center of the elastic retaining ring passes through the limiting block and is engaged in the second retaining block. The protruding ring can support the metal mesh cover from the bottom of the positioning ring, fixing the metal mesh cover between the cup body and the cup mouth to prevent it from falling off here.

[0014] (2) A pull ring is welded to the center of the top of the film. The pull ring has a groove inside for fingers to pass through. The pull ring is located at the center of the bottom of the inside of the metal mesh cover, which makes it easy for fingers to hook. When disassembling or installing the elastic buckle, the metal mesh cover can be inserted or pulled out longitudinally. The metal mesh cover has multiple uniform mesh holes, which can filter out tea leaves and only allow tea water to pass through for people to drink, which is very convenient.

[0015] (3) By setting a bottom at the bottom of the outside of the cup body, the groove above the bottom of the cup body matches the protrusion on the lower surface of the cup body. The two are locked together, which not only thickens the bottom of the cup body, but also stabilizes the center of gravity of the cup body. When the cup body is placed vertically on a flat surface, it can prevent the cup body from falling over automatically, avoid the liquid stored in the cavity inside the cup body from flowing out, and also prevent the cup body from transferring heat to the table below.
