The positioning step 21 is pressed against the edge of the upper end opening of the machine body 1, and the second sealing ring 5 of the end cover 2 is partially squeezed into the brewing cavity 10. One end of the body 1 is provided with a filter cover 3 which can cover the opening of the other end of the brewing chamber 10 and can move into the brewing chamber 10. The filter cover 3 can move and seal the opening of the other end of the brewing chamber 10 to prevent water from flowing out. The filter cover 3 is covered with a first sealing ring 4 which can be squeezed with the inner wall of the brewing chamber 10. The side wall of the filter cover 3 is provided with a first sealing ring groove 32 for the first sealing ring 4 to be installed. The first sealing ring 4 is arranged on the filter cover 3, so that the brewing chamber 10 can form a relatively closed space. The filter cover 3 is provided with a filter hole 31. When brewing tea, coffee, etc., the cup squeezes the filter cover 3 to move toward the brewing chamber 10, and the tea and coffee water are filtered out from the filter hole 31 and enter the cup. As the filter cover 3 is squeezed into the brewing chamber 10, the pressure in the brewing chamber 10 increases, and the tea, coffee, etc. flow out from the filter hole 31 and enter the cup body.

[0030] When in use, there are two ways of using. In one way, filter paper 36 is placed on the filter cover 3, coffee powder, tea leaves, tea bags, etc. are placed on the filter paper 36, and the filter cover 3 is loaded from the lower end of the body 1 (the lower end of the brewing chamber 10) (or filter paper 36 is placed on the filter cover 3, the filter cover 3 is loaded from the lower end of the body 1, and coffee powder, tea leaves, tea bags are put in from the upper end of the brewing chamber 10), water is put into the upper end of the brewing chamber 10, and the upper end of the body 1 is covered with the upper end cover 2, so that the filter cover 3 is at the bottom, the upper end opening of the cup is pressed against the bottom of the filter cover 3, and the body 1 is pressed down to squeeze the filter cover 3 upwards for brewing. Cavity 10, allowing tea or coffee to flow into the cup; another way of using is to cover the upper end cover 2 of the body 1, turn it upside down, remove the filter cover 3, expose the opening of the brewing cavity 10, and then put coffee or tea bags and water into the opening, cover the filter cover 3, and for the convenience of filtering, set filter paper 36 on the filter cover 3 during brewing, press the opening of the cup against the filter cover 3, and finally turn it upside down, let the filter cover 3 and the cup at the bottom, and then let the cup and the filter cover 3 be squeezed together, so that tea or coffee can flow into the cup, and no water will pour out in this way.

[0031] Embodiment 2, as Figure 6-9As shown, the lower end portion in the figure is divided into a cup. The difference from the first embodiment is that the second sealing ring is installed at a position and an exhaust structure is provided.

The end cover 2 is inserted so that the inner side of the end cover 2 and the outer wall of the body 1 squeeze the second sealing ring 5 to achieve sealing. The second sealing ring 5 is outside the body 1, which can increase a certain space of the brewing chamber 10. An air discharge hole 33 for discharging air in the cup is provided at one end where the filter cover 3 is squeezed with the cup body. When the opening of the cup abuts against the filter cover 3, the air discharge hole 33 can be connected with the inside of the cup, so that the space in the cup is connected with the outside, which is convenient for discharging air in the cup. A further structure is that the filter cover 3 is provided with a support step 34 for the cup to support and a guide ring 35 that can be inserted into the cup, and the air discharge hole 33 is provided on the support step 34 and the guide ring 35. When the open end of the cup is supported on the support step 34, the support step 34 and the air discharge hole 33 on the guide ring 35 are connected, and the guide ring 35 can be close to the inner wall of the cup, which is convenient for positioning and use. The use method of this embodiment is the same as that of the first embodiment, and there are two use methods, that is, the cup can be on the top or the bottom when filling water, coffee, tea, etc.

[0032] Embodiment three, as Figure 10-12 As shown, the difference from the second embodiment is that the connection method of the end cover 2 is different. A positioning boss 11 is provided on the outer wall of the upper end of the body 1, and the upper end opening of the brewing chamber 10 is inserted into the end cover 2, and the lower end of the end cover 2 is against the positioning boss 11. A convex buckle 23 is provided on the inner wall of the end cover 2. The outer wall of the body 1 is provided with a buckle groove 12 for the convex buckle 23 to buckle when the end cover 2 rotates.
