Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a vacuum non-tumbler cup. Background Art

[0002] Cups are common daily necessities. However, during use, cups often tip over, causing problems such as breakage or damage, spillage of water, and other inconveniences for users. Therefore, improvements to the cup's bottom structure are needed. To address this pain point, a current solution involves adding a suction cup made of silicone or soft material to the bottom of the cup. This suction cup's properties and the pressure difference within the suction chamber create a secure bond between the cup and the tabletop.

[0003] Currently, the most common non-tumbler structure in the industry uses a silicone suction cup to adhere to a flat surface, and then releases the cup through pressure relief. There are two ways to release pressure: one is to directly pull up the cup through external force, but in this process, the liquid in the cup can easily spill due to inertia. The other is to control the cup's adhesion and release to the flat surface through mechanical structures such as buttons, such as those shown in patent application publication number CN109316012A. This is relatively cumbersome to operate, and the mechanical structures such as buttons on the outside can also detract from the overall aesthetic. To overcome these issues, a vacuum non-tumbler that automatically adheres and releases is needed. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the figures only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0030] Example 1:

[0031] like Figures 1 to 7As shown, a vacuum tumbler includes a cup body 1, which is used to hold liquid; it also includes an exhaust valve 2, a motor 3, a control module 4, a suction cup 5, a sensing module 6 and a power supply 7 for forming adsorption; the suction cup 5 is arranged at the bottom of the cup body 1, and is provided with an air hole 51 connected to the exhaust valve 2 inside the cup body 1. The air hole 51 is connected to the exhaust valve 2, and the exhaust valve 2 extracts the gas between the suction cup 5 and the table to form a low-pressure environment; in this example, the air hole 51 is located at the center of the circular suction cup 5; the exhaust valve 2 is arranged at the bottom of the cup body 1, and the exhaust valve 2 is also connected to the motor 3 for transmission, and the exhaust is controlled by the motor 3 to achieve exhaust; the motor 3 is also connected to the control module 4, which controls the start and stop of the motor 3, and the control module 4 is also connected to the sensing module 6 and the power supply 7 respectively; the sensing module 6 is arranged in the cup body 1, and the sensing module 6 is used to sense the grasping of the water cup; it should be noted that the way in which the sensing module 6 senses the grasping of the hand is an existing way, including but not limited to the existing pressure sensing, human body inductance sensing, etc.

[0032] In this example, human body inductance sensing is used, wherein when the skin touches the cup, the sensing module 6 will sense a change in the inductance value. The sensing module 6 is located inside the cup wall of the cup body 1, and the sensing module 6 includes an inductor element. The sensing module 6 also includes a plurality of inductive sensing lines 61, which are spirally distributed inside the side wall of the cup body 1 or vertically distributed inside the side wall of the cup body 1; the plurality of sensing lines 61 are arranged at equal angles, and adjacent sensing lines 61 are spaced at a set angle. When two or more sensing lines 61 sense a change in the inductance coefficient, it is considered that the cup will be picked up, and then the exhaust valve 2 is controlled to remove the low-pressure environment inside the suction cup 5, so that the cup body 1 is desorbed from the desktop.

[0033] The exhaust valve 2 includes a cavity 21, a pull rod 22, a piston 23 and a sealing ring 24; one end of the pull rod 22 is fixedly connected to the piston 23, and the piston 23 is slidably arranged in the cavity 21; the cavity 21 is also connected to the air hole 51 on the suction cup 5; the other end of the pull rod 22 passes through the cavity 21 and is transmission-connected to the motor 3 outside the cavity 21, and the sealing ring 24 is slidably arranged on the pull rod 22, and the sealing ring 24 is located in the cavity 21; an elastic member is also provided between the sealing ring 24 and the piston 23; in this example, the elastic member is a spring 26, and one end of the spring 26 is against the piston 23. When adsorption is required, the motor 3 controls the pull rod 22 to pull out of the cavity 21. The pull rod 22 will first drive the piston 23 to move. Due to the action of the spring 26, the sealing ring 24 will be pressed against the inner wall of the cavity 21 after moving a certain distance, so that the inside of the cavity 21 forms a closed space except for the air hole 51. As the piston 23 continues to move, the excess gas will be discharged from the air hole 51. Finally, when the motor 3 releases the pull rod 22, due to the action of the spring 26, the piston 23 is pushed away from the motor 3, so that a low-pressure environment is formed in the cavity 21, cooperating with the suction cup 5 to form adsorption. When the adsorption needs to be released, the motor 3 controls the pull rod 22 to move in the opposite direction until the spring 26 can no longer press the sealing ring 24 against the inner wall of the cavity 21. At this time, gas enters the cavity 21 from the part of the cavity 21 where the pull rod 22 passes, so that the air pressure inside the cavity 21 is balanced with that of the external space, and the adsorption state between the suction cup 5 and the desktop is released.

[0034] The pull rod 22 is provided with a rack 25 that cooperates with the motor 3. The output end of the motor 3 is provided with a gear 31. The gear 31 is engaged with the rack 25 to facilitate the control of the telescopic movement of the pull rod 22 through the forward and reverse rotation of the motor 3.

[0035] The suction cup 5 is arranged in the circular recessed area at the bottom of the cup body 1. An air hole 51 is provided in the middle position of the suction cup 5. The air hole 51 passes through the bottom of the cup body 1 and is connected to the cavity 21 in the cup body 1. The lower surface of the suction cup 5 is set to be flat, which facilitates the discharge of the gas compressed by the piston 23 through the air hole 51.

[0036] The control module 4 is arranged in a circular shape inside the cup body 1, and a motor 3 and an exhaust valve 2 are provided in the middle area of ​​the control module 4; the control module 4 is arranged in a ring shape, which facilitates the connection between the control module 4 and the sensing module 6 set on the cup body 1, making the overall structure more reasonable and reducing the space occupied in the cup body 1; the cup body 1 is also provided with a charging port 11 for charging the power supply 7, and the charging port 11 is connected to the control module 4.

[0037] During the implementation process, the motor 3 is set to control the action of the exhaust valve 2 to realize automatic adsorption or desorption of the suction cup 5. On the one hand, the water cup can be sucked on the table to prevent the water cup from tipping over when placed. On the other hand, it is convenient to use; by setting the structure of the exhaust valve 2 and cooperating with the motor 3, a low-pressure environment is formed in the control cavity 21 or it is connected to the external atmosphere; by setting the charging port 11, the power supply 7 is repeatedly charged and used to improve the overall service life.

[0038] The above description is merely a specific example of the present invention and does not constitute any limitation thereto. It is obvious that those skilled in the art, after understanding the content and principles of the present invention, may make various modifications and changes in form and details without departing from the principles and structure of the present invention. However, such modifications and changes based on the concept of the present invention are still within the scope of protection of the claims of the present invention.
