Description

Technical Field

[0001] The utility model belongs to the technical field of water cups and relates to a knob-type tea brewing cup. Background Art

[0002] Existing fully functional tea sets have many functional parts, the brewing process is complicated, and the volume after storage is relatively large. For tea lovers who like to travel, they will encounter problems such as inconvenience in carrying and easy restrictions on brewing conditions. On the other hand, single-function tea sets cannot control the tea brewing time and speed at will, cannot enjoy the fun of the brewing process, and are inconvenient to clean.

[0003] For example, the tea brewing cup with application number 2016210860155 has two cup bodies respectively arranged at both ends of the valve body. After brewing through one of the cup bodies, the valve body is turned on and the tea flows into the other cup body for drinking. The brewing time and the concentration of the tea can be conveniently controlled, and the two cup bodies can be removed separately, which is convenient for cleaning.

[0004] However, in actual use, this type of tea cup has the following disadvantages: the internal water retaining member used for sealing is lifted by a lever connected to the button.

[0027] A mounting portion 7 integrally formed with the connecting sleeve 3 is fixedly provided on the connecting sleeve 3 . A mounting hole 8 is provided on the mounting portion 7 . The knob assembly is horizontally rotatably disposed in the mounting hole 8 .

[0028] like Figure 7 As shown, the knob assembly includes a knob rod 10, a knob sleeve 11 fixed to the outer end of the knob rod 10, and an indicator key 20 is provided on the outer surface of the knob sleeve 11. The indicator key 20 is used to indicate the direction of the water hole 6. It is convenient for the user to judge whether the state of the water passage is open or closed at this time.

[0029] like Figure 5 As shown, a plurality of stop rods 12 are fixedly provided at the inner end of the knob rod 10, and a stop protrusion 13 is fixedly provided on the stop rod 12. When the knob stem is pushed laterally into the mounting hole 8, the inner wall of the mounting hole 8 squeezes the stop protrusion 13 and the stop rod 12 to deform until the stop protrusion 13 extends out of the mounting hole 8. The stop rod 12 recovers its deformation, and the stop protrusion 13 can be blocked by the mounting portion 7 to prevent the knob assembly from escaping from the mounting hole 8.

[0030] like Figure 6 As shown, an angle limiting mechanism for limiting the rotation angle of the knob assembly is also provided between the knob assembly and the mounting portion 7. The angle limiting mechanism includes a limiting arc groove 14 provided on the inner wall of the mounting hole 8 and a limiting block 15 fixed on the knob rod 10.

The limiting block 15 is rotatably arranged in the limiting arc groove 14. The knob assembly is rotated back and forth 90°, and the corresponding limiting blocks 15 are respectively rotated to abut against the two side walls of the limiting arc groove 14. Two limiting convex strips 16 are also fixed on the inner wall of the limiting arc groove 14. The knob assembly is rotated so that the limiting block 15 passes over the corresponding limiting convex strips 16 and abuts against the side wall of the limiting arc groove 14. The limiting block 15 can be blocked by the limiting convex strips 16 to limit the position of the knob assembly after rotation.

[0031] like Figure 4 As shown, a filter screen 17 is embedded on the top of the connecting sleeve 3, and an installation slot is provided on the inner top surface of the connecting sleeve 3. A sealing ring 18 is fixedly embedded in the installation slot. A circle of limiting bosses is fixed on the inner side wall of the sealing ring 18. The filter screen 17 presses the limiting boss downward, and the filter screen 17 can be blocked by the limiting boss after passing over the limiting boss. The upper cup body 1 is connected to the connecting sleeve 3 by threads, and the bottom of the upper cup body 1 extends downward into the connecting sleeve 3 and presses against the sealing ring 18, so that a circumferential seal is formed between the upper cup body 1 and the connecting sleeve 3. The filter screen 17 is detachably fixed with a handle 19 for the user to grasp.

[0032] It should be understood that in the claims and description of the utility model, all "including..." should be understood as an open-ended meaning, that is, its meaning is equivalent to "at least contains...", and should not be understood as a closed meaning, that is, its meaning should not be understood as "only includes...".
