[0027] The structure of the present application will be described below based on the drawings, but the following description is not intended to limit the present application, and each component in the technical solution can be changed, replaced, combined, deleted, etc. without departing from the gist of the present application.

[0028] <Overall structure of cup>

[0029] In Figure 1 , a perspective view of a cup 1 of the present application is shown, as Figure 1 indicated, the cup 1 has a lower case 3 and an upper case 2, the lower case 3 is a cylinder with an open upper end, for receiving liquid therein, the upper case 2 is a cylinder with an open lower end opposite to the lower case 3, the upper case 2 is connected to the lower case 3 via a connecting member 4, whereby the open upper end of the lower case 3 is closed by the upper case 2 to prevent liquid from flowing out.

[0030] In Figure 2 , a plan view of the cup 1 is shown, Figure 2 the A-A view is a view passing through the center of the cup 1, i.e., in the plan view, Figure 2 in Figure 3 , the A-A view is a cross-sectional view angle bisecting the cup 1. In , the structure observed by the view angle of the A-A view is shown.

[0031] Figure 3 As indicated, the connecting member 4 is a cylinder with open upper and lower ends, and is mounted on the lower case 3 from above in a detachable manner, and the upper case 2 is mounted on the connecting member 4 from above in a detachable manner.

[0032] <Filter structure>

[0033] Inside the connecting member 4, a filter mesh 8 is mounted in a manner movable along the vertical direction, the filter mesh 8 has a mesh structure, the space inside the cup 1 on the upper side of the filter mesh 8 and the space on the lower side of the filter mesh 8 are communicated via the mesh of the filter mesh 8. There is a gap between the connecting member 4 and the filter mesh 8.

[0034] In this case, the structure that enables the filter screen 8 to move in the up-and-down direction is not limited, for example, as shown in Figure 3 the outer peripheral portion of the filter screen 8 has a guide protrusion 14, which can be formed in a part of the circumferential direction of the upper end of the filter screen 8, or can be formed in the entire circumferential direction of the upper end of the filter screen 8, that is, the guide protrusion 14 is continuously formed in the entire circumferential direction.

[0035] The connecting member 4 is formed with a boss 12 that protrudes inward, and the boss 12 is engaged by the guide protrusion 14, whereby the filter screen 8 can be mounted to the connecting member 4. The boss 12 can be formed in a part of the circumferential direction of the connecting member 4, or can be formed in the entire circumferential direction of the connecting member 4, that is, the boss 12 is continuously formed in the entire circumferential direction.

[0036] As shown in Figure 3 at a position outward of the boss 12, an inner peripheral wall 13 is extended upward, and the inner peripheral wall 13 is located outward of the guide protrusion 14, whereby the filter screen 8 can move in a space surrounded by the inner peripheral wall 13. Alternatively, the connecting member 4 can be provided with a guide groove 11 that extends upward and downward at the inner peripheral wall 13, and the guide protrusion 14 formed in the outer peripheral portion of the filter screen 8 is engaged with the guide groove 11 with a clearance, whereby the filter screen 8 can move upward and downward freely.

[0037] Alternatively, a guide rib that extends upward and downward can be provided at the inner peripheral wall of the connecting member 4, and a guide recess that engages with the guide rib with a clearance can be provided at the outer peripheral portion of the filter screen.

[0038] <Sealing structure>

[0039] As shown in Figure 3 at the lower portion of the upper housing 2, a groove that opens downward is formed, and the first sealing ring 9 is accommodated in the groove. When the upper housing 2 and the connecting member 4 are screwed together, the connecting member 4 can abut against the first sealing ring 9, whereby the first sealing ring 9 is mounted between the upper housing 2 and the connecting member 4, and it is preferable that the groove and the first sealing ring 9 are formed in the entire circumferential direction, whereby sealing is achieved in the entire circumferential direction.

[0040] The first sealing ring 9 can serve as the upper stop point of the filter screen 8, that is, when the filter screen 8 moves in the up-and-down direction and reaches the upper stop point of the up-and-down movement, the filter screen 8 comes into contact with the first sealing ring 9.

[0041] As shown in Figure 3As shown, a downward-opening groove is formed at the lower part of the connector 4, in which the second sealing ring 10 is housed. When the connector 4 is threaded together with the lower housing 3, the lower housing 3 can abut against the second sealing ring 10, thereby installing the second sealing ring 10 between the connector 4 and the lower housing 3. Preferably, the groove and the second sealing ring 10 are formed over the entire circumference, thereby achieving a seal over the entire circumference.

[0042] The above structure allows for sealing of the connection between the upper housing 2 and the connector 4, and the connection between the connector 4 and the lower housing 3, preventing liquid leakage.

[0043] <The process and effects of using cups>

[0044] like Figure 3 As shown, the cup 1 of this application may have: an ultrasonic transducer 6 disposed in the upper housing 2, the ultrasonic transducer 6 being used to generate ultrasonic vibration; an ultrasonic carrier 7 disposed in the upper housing 2, the ultrasonic carrier 7 being exposed at the lower end opening of the upper housing 2; and a control board 5 disposed in the upper housing 2, for controlling the vibration of the ultrasonic transducer 6.

[0045] When using the cup 1 of this application, the user first places the cup 1 upright, adds coffee powder or tea powder to the filter screen 8, and adds water to the lower housing 3. After adding all the ingredients, the user screws the connector 4 onto the lower housing 3 and the upper housing 2 onto the connector 4. Alternatively, the user can add coffee powder or tea powder to the filter screen 8 and add water while the connector 4 is screwed onto the lower housing 3, and then screw the upper housing 2 onto the connector 4. The user then inverts the cup 1 to mix the water and the powder, and then powers on the cup. The control board 5 controls the ultrasonic transducer 6 to vibrate. The ultrasonic transducer 6 transmits the vibration to the mixture of water and powder through the ultrasonic carrier 7 to achieve ultrasonic extraction. After the extraction is complete, the user places the cup 1 upright, allowing the extracted solution (coffee or tea) to fully mix with the water. The user then unscrews the upper housing 2 or the connector 4 and drinks the beverage.

[0046] When the cup 1 is placed upright, the filter screen 8 is located at the lower stop point of its vertical movement, i.e., the boss 12. As the cup 1 is inverted, the filter screen 8 moves towards... Figure 3 The filter 8 moves upward (in reality, downward), and the guide protrusion 14 on the outer periphery of the filter 8 is supported by the first sealing ring 9, thus stopping at the top dead center. After the ultrasonic extraction is completed, the user places the inverted cup 1 upright, and with this action, the filter 8 moves towards... Figure 4As the lower portion (the real lower portion) of the filter 8 moves upward, the space above the filter 8 communicates with the space below the filter 8 via the gap between the connecting member 4 and the filter 8, avoiding the situation that the liquid cannot pass through the filter 8 due to the surface tension and pressure of the liquid, so that the liquid can smoothly pass through the filter 8 and flow into the lower housing 3, and the filtering effect is achieved.

[0047] In addition, if a surface tension liquid film is formed on the mesh structure of the filter 8 due to the surface tension of the liquid, the movement of the filter 8 up and down can also generate a force on the surface tension liquid film, causing the surface tension liquid film to break and allowing the liquid to move smoothly.

[0048] <Modified Example>

[0049] The above describes the structure of the cup 1 having the upper housing 2, the lower housing 3, and the connecting member 4 for improving the user's operation experience. However, the present application can also not have the connecting member 4. That is, only the upper housing 2 and the lower housing 3 are provided.

[0050] In Figure 4 , a schematic view of the cup 1' having only the upper housing 2 and the lower housing 3 is shown, Figure 4 , the B-B view is a view that bisects the cup 1'. In Figure 5 , the B-B view is a view that bisects the cup 1'. In Figure 5 , the structure observed by the B-B view is shown.

[0051] As shown in Figure 5 , the cup 1' of the modified example includes a lower housing 3 in the shape of a cylinder with an open upper end, an upper housing 2 in the shape of a cylinder with an open lower end, which is mounted to the lower housing 3 from above in a detachable manner, and a filter 8 having a mesh structure, which is mounted to the lower housing 3 in a detachable and movable manner along the up-down direction, and the space above the filter 8 and the space below the filter 8 inside the cup 1 communicate via the mesh of the filter 8. There is a gap between the lower housing 3 and the filter 8.

[0052] A boss 15 protruding inward is formed on the lower housing 3, and the boss 15 is used to guide the locking of the protruding portion 14, so that the filter 8 can be mounted to the lower housing 3. The boss 15 can be formed on a part of the circumference of the lower housing 3, or can be formed on the entire circumference of the lower housing 3, that is, the boss 15 is continuously formed on the entire circumference.

[0053] As shown in Figure 5As shown, an inner peripheral wall 16 extends upward from a position outside the boss 15. The inner peripheral wall 16 is located outside the guide protrusion 14, thereby allowing the filter screen 8 to move within the space surrounded by the inner peripheral wall 16. Alternatively, the lower housing 3 may have a vertically extending guide groove 11 on the inner peripheral wall 16, and the guide protrusion 14 formed on the outer periphery of the filter screen 8 may be in clearance fit with the guide groove 11, thereby allowing it to move freely up and down.

[0054] Alternatively, guide ribs extending vertically are provided on the inner peripheral wall of the lower housing 3, and guide recesses that fit with the guide ribs are provided on the outer peripheral part of the filter screen.

[0055] In addition, such as ​ As shown, a downward-opening groove is formed in the lower part of the upper housing 2, and a first sealing ring 9 is housed in the groove. When the upper housing 2 and the lower housing 3 are threaded together, the lower housing 3 can abut against the first sealing ring 9, thereby installing the first sealing ring 9 between the upper housing 2 and the lower housing 3. Preferably, the groove and the first sealing ring 9 are formed over the entire circumference, thereby achieving a seal over the entire circumference.

[0056] The first sealing ring 9 can serve as the upper stop point of the filter screen 8, that is, when the filter screen 8 moves in the vertical direction and is located at the upper stop point of its vertical movement, the filter screen 8 contacts the first sealing ring 9.

[0057] By adopting the modified structure, the same effect as the above-described embodiment can be obtained.
