Description

Technical Field

[0001] This utility model relates to the field of tea brewing cup technology, specifically to a spiral telescopic tea brewing cup. Background Technology

[0002] In China, tea drinking has always required a teapot for brewing tea and a teacup for drinking tea. A teacup is a modern tea-drinking utensil that combines a teapot and a teacup. Most are made of glass or ceramic, but some are made of low-temperature plastic. They are portable and convenient for brewing tea anytime. A search revealed an existing technology (publication number: CN202321874651.4) for a spiral telescopic teacup. The technology describes a method that "utilizes a rotating part to easily control the filter inside the cup, reducing the number of times the lid needs to be opened and effectively keeping the tea warm. The filter separates the tea from the water through telescopic movement, allowing the tea leaves to completely detach from the water surface and effectively control the brewing time. The telescopic movement relies on the change in the intersection point of the spiral groove and spiral hole during relative rotation to control the height of the filter, providing flexible control." However, this existing technology suffers from the problem that when the spiral telescopic tea filter separates from the cup body along with the lid, residual tea on the tea leaves easily drips through the filter. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a spiral telescopic tea brewing cup is provided to solve the problem that, in existing technologies, when the spiral telescopic tea filter separates from the cup body along with the lid, residual tea water on the tea leaves easily drips out through the filter.

[0004] To achieve the above objectives, a spiral telescopic tea infuser is provided, comprising: a tea infuser body and a stainless steel lid, wherein the stainless steel lid is fitted onto the upper rim of the tea infuser body.

[0005] The stainless steel cup lid has a fixed spiral cylinder welded to its inner side. The inner side of the fixed spiral cylinder is connected to a telescopic plate through a threaded groove. A rotating support is fixed to the upper end of the telescopic plate. A connecting column is axially connected to the upper end of the rotating support. A tea filter is screwed to the lower end of the telescopic plate. A filter screen is provided on the side end of the tea filter. An elastic water-blocking gasket is sleeved on the lower side wall of the tea filter.

[0006] Furthermore, the inner surface of the stainless steel cup lid is connected to the outer thread on the side wall of the tea cup via an internal thread.

[0007] Furthermore, a first sealing ring is fixedly fitted onto the outer surface of the fixed spiral cylinder; and the first sealing ring is in contact with the inner wall of the tea cup opening.

[0008] Furthermore, the upper end of the rotating support column is connected to the stainless steel cup lid through a connecting column, and a column head is fixed to the upper end of the connecting column.

[0009] Furthermore, the surfaces of the rotating support column and the connecting column are both fitted with second sealing rings, and the outer surface of the telescopic plate is provided with threads.

[0010] Furthermore, the upper end of the tea filter cylinder is connected to the telescopic plate via a threaded section, and the threaded section is welded to the upper end of the filter cylinder surface.

[0011] Furthermore, the bottom of the tea filter cylinder is convex and arc-shaped, and the side end of the tea filter cylinder is correspondingly attached to the wall of the fixed spiral cylinder groove through an elastic water-blocking washer.

[0012] The beneficial effects of this utility model are as follows: the spiral telescopic tea cup of this utility model utilizes a rotating support column, a telescopic plate, a fixed spiral cylinder, a tea filter cylinder, and an elastic water-blocking washer to form a spiral telescopic structure. By manually rotating the rotating support column, the telescopic plate is driven to move upward along the threaded groove of the fixed spiral cylinder, causing the tea filter cylinder at the lower end of the telescopic plate to move upward and completely retract into the stainless steel cup lid. At this time, the elastic water-blocking washer on the lower side of the tea filter cylinder seals the residual tea water inside the filter cylinder within the fixed spiral cylinder, effectively preventing residual tea water on the tea leaves from dripping into the external environment when the tea cup lid is separated. This reduces the leakage and dripping of tea water from the tea cup, ensuring the cleanliness and hygiene of the tea-making table or countertop, and improving the practicality of the spiral telescopic tea cup.

Detailed Implementation

[0018] Reference Figures 1 to 4 As shown, this utility model provides a spiral telescopic tea brewing cup, including: a tea brewing cup body 1 and a stainless steel cup lid 2, with the stainless steel cup lid 2 attached to the upper rim of the tea brewing cup body 1.

[0019] A fixed spiral cylinder 4 is welded to the inner side of the stainless steel cup lid 2. A telescopic plate 33 is connected to the inner side of the fixed spiral cylinder 4 through a threaded groove 41. A rotating support column 3 is fixed to the upper end of the telescopic plate 33. A connecting column 31 is axially connected to the upper end of the rotating support column 3. A tea filter cylinder 5 is screwed to the lower end of the telescopic plate 33. A filter screen cylinder surface 51 is provided on the side cylinder end of the tea filter cylinder 5. An elastic water-blocking washer 52 is sleeved on the lower side cylinder wall of the tea filter cylinder 5.

[0020] First, place the tea leaves in the tea filter tube 5 and screw it onto the telescopic plate 33 inside the stainless steel cup lid 2. Pour water into the tea brewing cup 1 and close the lid. At this time, the tea leaves in the tea filter tube 5 are immersed in the water. After the tea leaves are soaked, rotate the rotating support column 3 to drive the telescopic plate 33 to move upward and rotate inside the fixed spiral cylinder 4. This causes the lower end of the telescopic plate 33, the tea filter tube 5, to move upward and enter the fixed spiral cylinder 4 until the tea filter tube 5 is completely inside the fixed spiral cylinder 4. Then, bend and retract the connecting column 31. When the stainless steel cup lid 2 is opened, the residual tea water in the tea filter tube 5 is sealed by the elastic water-blocking gasket 52. Then, scrape the lower end of the stainless steel cup lid 2 along the rim of the cup to remove the water from the lower end of the lid. This effectively prevents the residual tea water on the tea leaves from dripping into the external environment when the tea brewing cup lid is separated.

[0021] In this embodiment, the inner surface of the stainless steel cup lid 2 is connected to the outer thread of the side wall of the tea cup body 1 via an internal thread. The outer surface of the fixing screw cylinder 4 is fitted with a first sealing ring 21; and the first sealing ring 21 is in contact with the inner wall of the mouth of the tea cup body 1.

[0022] As a preferred embodiment, the first sealing ring 21 is flush with the lower surface of the fixed spiral cylinder 4, which serves to block water and prevent leakage. The first sealing ring 21 and the fixed spiral cylinder 4 are also flush with the lower surface of the stainless steel cup lid 2, which makes it convenient to scrape the water on the lower surface of the cup lid along the cup mouth when separating the stainless steel cup lid 2, thus preventing it from dripping to the outside.

[0023] In this embodiment, the upper end of the rotating support column 3 is connected to the stainless steel cup lid 2 through a connecting column 31, and a column head 32 is fixed to the upper end of the connecting column 31. A second sealing ring 34 is fitted onto the surface of both the rotating support column 3 and the connecting column 31, and the outer surface of the telescopic plate 33 is threaded. The upper end of the tea filter cylinder 5 is connected to the telescopic plate 33 through a threaded section 53, which is welded to the upper end face of the filter screen cylinder surface 51. The bottom of the tea filter cylinder 5 is a convex arc shape, and the side end of the tea filter cylinder 5 is correspondingly fitted to the groove wall of the fixed spiral cylinder 4 through an elastic water-blocking washer 52.

[0024] As a preferred implementation, the connecting column 31 can be folded and stowed to prevent the rotating support column 3 and the connecting column 31 from being too long. The rotating support column 3 drives the telescopic plate 33 to rotate forward and backward within the fixed spiral cylinder 4, realizing the downward extension and upward retraction of the tea filter cylinder 5. The elastic water-blocking gasket 52 on the side of the tea filter cylinder 5 can fit against the inner groove surface of the fixed spiral cylinder 4 as the tea filter cylinder 5 moves upward, blocking the tea water flowing out of the upper tea filter cylinder 5 from flowing downward, effectively preventing the tea water remaining on the tea leaves from dripping into the external environment when the tea cup lid is separated, thus reducing the leakage and dripping of tea water from the tea cup.

[0025] This utility model of a spiral telescopic tea infuser effectively solves the problem in existing technologies where residual tea leaves easily drip through the filter when the lid separates from the cup body. It effectively prevents residual tea leaves from dripping into the external environment when the lid is separated, thus reducing leakage and dripping, ensuring the cleanliness and hygiene of the tea table or countertop, and improving the practicality of the spiral telescopic tea infuser. It is suitable for spiral telescopic tea infusers.
