Description

Technical Field

[0001] The utility model relates to the technical field of thermos cups, in particular to a tea cup with a liftable tea strainer. Background Art

[0002] Commercially available thermoses are often fitted with filters to facilitate the removal of tea leaves after steeping. Currently, conventional filters are secured in a predetermined position by a filter retainer that snaps onto the cup body. This snap-on design facilitates quick removal of the filter to complete tea brewing. Due to its excellent performance, this design has become widely used. However, during use, some thermoses lack a proper seal and securement between the tea strainer and the inner wall of the cup body. This allows for the strainer to easily detach from the cup body when drinking, causing a large amount of boiling water to gush out and burn the lips.

[0003] In order to solve this technical problem, patent 201720629258.7 discloses a thermos cup with a tea strainer, comprising a cup body, a cup lid threadedly connected to the cup mouth of the cup body, a tea strainer sleeved on the cup mouth, a first sealing flange provided on the tea strainer, a sealing ring sleeved on the first sealing flange, a first sealing groove provided in the sealing ring; a crimping ring provided on the tea strainer, a second sealing flange provided on the crimping ring, the second sealing flange clamped in the first sealing groove, and a second sealing groove provided on the crimping ring. The first sealing ring is sleeved in the second sealing groove; a crimping flange is provided on the side of the crimping ring, and the crimping flange is buckled on the side edge of the opening of the cup body. The sealing ring seals and buckles the tea strainer with the crimping ring, and the crimping flange is buckled on the opening of the cup body to fix the position of the tea strainer, and the first sealing ring is used to seal the gap between the crimping ring and the cup body, so that the water in the cup body can only overflow from the tea strainer; the crimping flange covers the outward side edge of the cup body. When drinking water, the lips do not need to directly touch the cup body to avoid scalding the lips, which is convenient and practical.

[0004] Although the above-mentioned existing technology can solve the problem of burning the mouth due to accidental detachment during leak detection, there are still some problems in actual use. Since the tea leaves are placed between the tea strainer and the bottom of the cup, and as the soaking time increases, the tea leaves will gradually sink to the bottom of the cup, which will cause the tea leaves to be unable to move up and down with the changes in the water level in the cup. However, during the actual soaking process, the soaking time required for the tea leaves varies depending on the type of tea, the temperature of the water, and the taste requirements of the tea drinker. However, at this time, the tea leaves in the cup body are always immersed in water, and it is impossible to adjust the corresponding soaking time in time to meet the corresponding tea drinking requirements. Therefore, it is urgent to solve this problem. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a teacup with a liftable tea strainer.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A teacup with a liftable tea strainer comprises a cup body, a bracket mounted on the cup body, and a tray that can slide linearly up and down inside the cup body and divide the interior of the cup body into two upper and lower chambers. The tray is used to hold tea leaves and is provided with a water filter hole for filtering the tea leaves. A straw that extends into the bottom of the cup is rotatably mounted on the bracket, and the rotation axis of the straw is parallel to and spaced apart from the axis of the cup body. The straw is a hollow threaded tube, and a threaded hole is provided at an eccentric position of the tray. The straw is coaxially inserted into the threaded hole and forms a threaded transmission fit with the threaded hole.

[0008] As a further solution of the present invention: a water filter tray is coaxially elastically interference-fitted at the bottom of the cup cavity, which divides the lower chamber into two sub-chambers; the water filter tray is provided with a filter hole for filtering tea leaves; a guide hole is penetrated by an eccentric part of the water filter tray, and an axially extending guide groove is provided on the hole wall of the guide hole; the bottom end of the straw is coaxially connected and fixedly connected to a cylinder with a clearance fit in the guide hole, and a protrusion is installed on the outer circumferential surface of the bottom end of the cylinder, which can pass through the guide hole along the guide groove.

[0009] As a further solution of the present invention: the cup mouth is coaxially elastically interfering with the cup cover, and a rotating hole is opened at the eccentric position of the cup cover; the top end of the straw is coaxially connected and installed with a rotating sleeve, and the rotating sleeve is coaxially rotatably installed in the rotating hole, and the cup cover constitutes the bracket.

[0010] As a further solution of the present invention: the rotary sleeve is a three-section stepped shaft with a thin middle and thick ends. The rotary hole is installed between the two shaft shoulders of the rotary sleeve, and a driving part for rotating the straw is also installed on the rotary sleeve.

[0011] As a further solution of the present invention: the driving part includes paddles installed on the outer circular surface of the top of the rotating sleeve in sequence along the circumference of the rotating sleeve, and a rotating sleeve coaxially fixedly sleeved on the top of the rotating sleeve after the paddles are installed; the bottom end of the catheter passes through the sleeve hole of the guide rotating sleeve and is coaxially elastically interference fit in the rotating sleeve, and a limiting ring is also installed on the tube body of the catheter to press the rotating sleeve onto the rotating sleeve when the catheter is inserted into the rotating sleeve.

[0012] As a further solution of the present invention, a snap-in hole is formed at the bottom end of the rotating sleeve, the shape of which matches the shape of the top of the rotating sleeve after the paddle is installed, so as to drive the rotating sleeve to rotate.

[0013] As a further solution of the present invention, a rotating tube is installed at the top end of the catheter.

[0014] As a further solution of the present invention, a cavity for holding tea leaves is provided on the upper surface of the tray, and a water filter hole is provided on the bottom surface of the cavity.

[0015] As a further solution of the present invention, an elastic sealing ring is coaxially sleeved on the outer circumferential surface of the cup lid inserted into the cup opening.

[0016] As a further solution of the present invention, a handle is installed on the outer circumferential surface of the cup body.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When you need to adjust the degree of tea soaking, you can move the tray up and down by rotating the straw; when the tray rises, the tea leaves are lifted and away from the water surface, reducing the contact area between the tea leaves and the water, thereby slowing down the soaking speed of the tea; when the tray drops, the tea leaves are closer to the water surface, increasing the soaking speed.

[0019] 2. The design of the water filter hole ensures that the tea can flow smoothly through the tray while preventing the tea leaves from entering the straw or the drinking part of the teacup.

[0020] 3. The diameter of the water filter hole in the utility model is larger than the diameter of the filter hole. This design allows for double filtration, preventing customers from inhaling too much tea leaves when drinking with a straw, thereby improving the comfort of tea drinking.

[0021] 4. In the present invention, the holes on the cup cover, tray, and water filter are all set in an eccentric manner. When the straw is rotated, the inner wall of the cup cavity constitutes a limiting part, and there is no need to set an additional limiting component, which simplifies the structure. Moreover, under the limiting action of the inner wall, the tray can move up and down along the inner wall, thereby adjusting the soaking time of tea leaves in the tea water.

[0022] 5. The advantage of this utility model's lifting design is that it fully takes into account the drinking preferences of modern young people, especially the trend of drinking fruit tea and milk tea with toppings. The lifting tea compartment design can easily lift ingredients that are difficult to suck out through a straw, allowing them to be eaten directly, increasing the fun and satisfaction of drinking. At the same time, this design also solves the problem of tea drinks sold in stores being inconvenient to carry after opening and difficult to distinguish the drinking state after filling ordinary cups, thereby improving the consumer's drinking experience and convenience.

[0023] 6. The curved rotating tube is swivel-mounted on the top of the conduit using a common sleeve method. After the conduit is rotated a certain angle, the rotating tube can be rotated to the appropriate drinking position on the top of the conduit. This design not only improves drinking comfort by eliminating the need for users to twist their bodies or heads due to improper straw positioning, but also greatly enhances the convenience of drinking, allowing users to easily enjoy their drinks at any angle. This user-friendly design will undoubtedly win the favor of consumers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 5 The cup cavity of the cup body 1 is a two-stage cavity that gradually shrinks from top to bottom, and the tray 3 serving as a tea strainer slides in the upper cavity, with the hole shoulder of the cup cavity being the downward limit of the tray 3. The disc-shaped water filter 4 is placed in the cup cavity, and then the water filter 4 is pressed to the bottom of the cup cavity by manual downward pressure, so that it is coaxial with the cup cavity. At the same time, the sealing ring coaxially sleeved on the outer edge of the water filter 4 forms an elastic interference fit with the bottom of the cup cavity, thereby fixing the water filter 4 to the bottom of the cup cavity. Then, the rotary plug is installed in the rotary hole 21 of the cup cover 2, and then the snap-in hole 531 on the rotating sleeve 53 is aligned with the paddle 511 on the top of the rotating sleeve 51 and plugged together. Finally, the bottom of the conduit 54 is plugged into the rotating sleeve 51, and the rotating sleeve 53 is pressed against the rotating sleeve 51 by the limiting ring 541, thereby completing the rotary matching installation of the straw 5 and the cup cover 2.

[0032] Before installing the straw 5, the tray 3 is coaxially pressed into the cup cavity, achieving an elastic interference fit with the sealing ring on the outer edge of the tray 3. The straw 5 is then inserted into the threaded hole 32 on the tray 3. Tea leaves and boiling water are poured onto the tray 3. Finally, the cylindrical portion 52 at the bottom of the straw 5 is inserted into the guide hole 42 on the drain pan 4. The protrusion 521 slides through the guide groove 421 and out of the guide hole 42. The cup lid 2 is now closed over the cup mouth, and the tea leaves are steeped. The tea leaves are steeped in the water for a certain period of time by rotating the rotating sleeve 53. To ensure the correct position of the tea leaves, the cup body 1 is made of a transparent material.

[0033] When drinking water using the straw 5 , the tea passes through the water filter holes 31 and the filter holes 41 in sequence, and then enters the oral cavity via the straw 5 , the conduit 54 and the rotating tube 55 to complete the drinking.

[0034] After brewing the tea, the straw 5 is rotated to displace the projection 521 and the guide groove 421. The projection 521 and the lower end surface of the guide hole 42 abut against each other, so that the water filter tray 4 and the tray 3 can be taken out of the cup cavity together, thereby facilitating quick cleaning.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
