[0003] A thermos cup, referring to Figure 1 , comprising a cup body 1 and a cup cover 2; a filter cup 3 is arranged in the cup body 1, and filter holes are arranged through the filter cup 3. When using, the filter cup 3 can be taken out first, and then tea leaves are put into the cup body 1 and hot water is poured; and then the filter cup 3 is put into the cup body 1. When drinking water, the filter cup 3 can block the tea leaves in the cup body 1; the tea water flows out from the filter holes for drinking, thereby reducing the possibility of the tea leaves flowing into the mouth of the drinker along with the tea water.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the tea in the cup is generally drunk in multiple times. After each drinking, the remaining tea in the cup continues to soak the tea leaves. However, the tea soaked in tea leaves for a long time tends to become bitter, so there is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a thermos cup, so as to control the time for the tea in the thermos cup to soak the tea leaves.

[0006] The present application provides a thermos cup adopting the following technical solution:

[0008] By adopting the above technical solution, the operation block and the magnetic part are magnetically attracted to attract the tea brewing net cup, so that static friction is generated between the tea brewing net cup or the magnetic part and the inner side wall of the cup body, and between the operation block and the outer side wall of the cup body, so that the operation block and the tea brewing net cup can be fixed at any position of the cup body at the same time. By moving the operation block, the operation block can drive the magnetic part and the tea brewing net cup to move, so that the tea brewing net cup can be moved to a position above the liquid level in the cup body, so that the tea brewing object in the tea brewing net cup is separated from the tea in the cup body, so as to control the time for the tea brewing object to be soaked in the tea, which is conducive to reducing the possibility of bitterness caused by long-term soaking of tea leaves in the tea water.

[0009] Optionally, the outer side wall of the cup body is provided with a clearance hole, and the operating block is located in the clearance hole.

[0010] By adopting the above technical solution, the operation block is located within the relief hole, which is conducive to reducing the distance between the operation block and the magnetic member, increasing the interaction force between the magnetic member and the operation block, and thus improving the stability of the operation block driving the magnetic member and the tea brewing net cup to move. At the same time, the operation block being located within the relief hole is conducive to reducing the possibility of the operation block being accidentally touched and moving.

[0011] Optionally, the cup body includes an inner housing and an outer housing sleeved outside the inner housing, and the inner side wall of the outer housing is connected to the outer side wall of the inner housing; the cup lid is used to be sleeved outside the inner housing or outside the outer housing; the relief hole is provided through the outer side wall of the outer housing; a heat insulation groove body is inserted into the inner side wall of the relief hole, and the heat insulation groove body abuts against the outer side wall of the inner housing; the operation block is located within the heat insulation groove body.

[0012] By adopting the above technical solution, the inner housing and the outer housing cooperate with each other to improve the heat preservation effect of the cup body. The operation block can move along the inner bottom wall of the heat insulation groove body to drive the magnetic member and the tea brewing net cup to move. The heat insulation groove body can block the gap between the inner housing and the outer housing at the position of the relief hole to reduce the heat exchange between the gas between the inner housing and the outer housing and the external gas, thereby being conducive to ensuring the heat preservation effect.

[0017] Optionally, a docking sleeve is provided along the circumference of the mouth of the tea brewing net cup, and a cover body for blocking the docking sleeve is provided on the inner peripheral wall or the outer peripheral wall of the docking sleeve.

[0018] By adopting the above technical solution, the cover body is sleeved on the outer wall of the docking sleeve to block the mouth of the tea brewing net cup, which is conducive to reducing the risk of tea brewing materials being dispersed in the inner shell and accidentally ingested by the drinker. When the tea brewing materials need to be cleaned, the tea brewing net cup only needs to be poured out and the cover body removed to clean out the tea brewing materials, which is simple and quick to operate.

[0020] By adopting the above technical solution, when installing the cover body, first insert the cover body into the docking sleeve, and then rotate the cover body until the docking protrusion is tightly pressed against the side wall of the mounting block close to the tea brewing net cup; at this time, the cover body is tightly pressed against the end wall of the docking sleeve, and an interaction force is generated between the docking protrusion and the mounting block, thereby increasing the friction between the docking protrusion and the mounting block, and reducing the possibility of the cover body rotating and separating from the docking sleeve. When the cover body is installed, when the docking protrusion is in contact with the side wall of the mounting block on the side away from the tea brewing net cup, the docking protrusion can automatically slide along the side wall of the mounting block to drive the cover body to rotate until the docking protrusion is separated from the mounting block, so that the end wall of the cover body is in contact with the end wall of the tea brewing net cup. At this time, the cover body can be tightened, which is simple and convenient to operate.

[0025] Optionally, a contact protrusion is provided between the magnetic member and the inner side wall of the cup body, and the contact protrusion is connected to the magnetic member.

[0026] By adopting the above technical solution, the contact protrusion can reduce the contact area between the magnetic member and the inner side wall of the cup body, so as to reduce the friction force between the magnetic member and the inner side wall of the cup body, thereby facilitating the movement of the magnetic member along the inner side wall of the cup body with the operation block.

[0027] The attraction of the operation block to the magnetic member and the friction force between the magnetic member and the inner side wall of the cup body cooperate with each other to keep the magnetic member fixed to the inner side wall of the cup body; by increasing the magnetism of the magnetic member to increase the attraction of the operation block to the magnetic member, the stability of the magnetic member and the tea brewing net cup being fixed can be ensured.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By moving the operation block, the tea brewing net cup can be moved to a position above or below the liquid level in the cup body to control the time for the tea brewing material to be soaked in the tea water, thereby facilitating reducing the possibility of the tea water being bitter.
