DETAILED DESCRIPTION

[0030] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] First embodiment

[0032] like Figure 1 As shown, the cup plug 100 includes:

[0033] A drinking body 110 is provided with a lower drinking port 112 , the cross-sectional dimensions of which gradually decrease from top to bottom, and a portion of the inner wall of the lower drinking port 112 is recessed to form an air guide groove 112 a;

[0034] The sealing member 120 can be plugged and removed to plug the lower drinking opening 112, and when the sealing member 120 plugs the lower drinking opening 112, the sealing member 120 can at least fit the middle section of the air guide groove 112a.

[0035] The lower end of the drinking body 110 is connected to the cup body 200, and the lower drinking spout 112 connects to the interior of the cup body 200. Thus, when a user aligns their mouth with the upper end of the drinking body 110 and pours the cup 200, the liquid in the cup body 200 enters the user's mouth through the lower drinking spout 112. The seal 120 is made of a flexible material, such as rubber. When plugged into the lower drinking spout 112, the seal 120 elastically deforms to conform to the inner wall of the lower drinking spout 112 and the air guide groove 112a, preventing liquid leakage from the body 200 when the cup is not in use. The air guide groove 112a allows for ventilation by simply loosening the seal 120, balancing the air pressure inside and outside the cup body 200 and making it easy to remove without becoming stuck.

[0036] like Figure 2 and Figure 3 As shown, the lower drinking port 112 includes a chamfered portion 112b and an opening portion 112d of different shapes, and a connecting portion 112c connected between the chamfered portion 112b and the opening portion 112d. The opening portion 112d is exposed on the lower bottom surface of the drinking body 110, and the air guide groove 112a is located on the inner walls of the chamfered portion 112b and the connecting portion 112c.

[0037] The cross section of the chamfered portion 112b is circular, and the cross section of the chamfered portion 112b gradually decreases from top to bottom. Figure 3 The connection between the chamfered portion 112b and the connecting portion 112c is an annular edge 112e. Figure 3 From the top-down angle shown, the width of the opening 112d is the largest in the middle, and the width from the middle to the left side of the opening 112d gradually decreases. There is a gap between the left side of the opening 112d and the annular edge 112e. The width from the middle to the right side of the opening 112d is roughly equal, and the right side of the opening 112d is connected to the annular edge 112e.

[0038] Continue to refer Figure 3 The upper end of the drinking body 110 is provided with a cup spout 114, wherein the cup spout 114 corresponds to the left side of the opening 112d. Thus, when the user aligns his mouth with the cup spout 114 and pours the cup body 200, the liquid in the cup body 200 flows along the left side of the opening 112d and enters the user's mouth through the cup spout 114. Since the width of the opening 112d gradually decreases from the middle to the left side, it prevents a large amount of liquid from gushing out and spilling on the user's clothes.

[0039] The height of the connecting portion 112c is greater than that of the chamfered portion 112b and the opening 112d. The connecting portion 112c is the highest and has an inner wall that is curved to accommodate connections between chamfered portions 112b and openings 112d of different shapes.

[0040] like Figure 1 and Figure 2 As shown, one end of the air guide groove 112a is located on the inner wall of the chamfered portion 112b, and the other end of the air guide groove 112a passes through the connection between the chamfered portion 112b and the connecting portion 112c and extends to the inner wall of the connecting portion 112c. The depth of the air guide groove 112a can be adjusted as needed and is not described here in detail.

[0041] The seal 120 has a hollow hemispherical structure, and the seal 120 fits with the connection between the chamfered portion 112b and the connecting portion 112c, that is, the seal 120 fits with the middle section of the air guide groove 112a, while the upper and lower sections of the seal 120 may not be filled by the seal 120. In this way, when a small force is applied to the seal 120 to pull it out, ventilation can be achieved, so that the seal 120 can be easily pulled out.

[0042] refer to Figure 2 The height of the connecting portion 112c is greater than the height of the chamfered portion 112b, so the length of the air guide groove 112a on the inner wall of the chamfered portion 112b may be less than the length of the air guide groove 112a on the inner wall of the connecting portion 112c.

[0043] like Figure 2 and Figure 3 As shown, the drinking body 110 is further provided with an upper drinking port 111, which connects the upper bottom surface of the drinking body 110 and the lower drinking port 112. The cross-sectional size of the upper drinking port 111 is larger than the cross-sectional size of the upper drinking port 111, so as to form a step 113 between the upper drinking port 111 and the lower drinking port 112.

[0044] A cup spout 114 is provided at the upper end of the upper drinking port 111, and the lower drinking port 112 can be deviated from the center of the upper drinking port 111 and provided close to the cup spout 114, thereby improving the user's drinking experience and preventing water from spilling.

[0045] Specifically, one side of the upper bottom surface of the upper drinking port 111 is raised upward to form a connecting rib 113b, and the cup spout 114 is provided on the connecting rib 113b.

[0046] like Figure 1As shown, the upper drinking water port 111 can be used to accommodate the lower part of the inner plug flip cover 130. Specifically, one side of the inner plug flip cover 130 is hinged to the upper bottom surface of the drinking water body 110, and the other side of the inner plug flip cover 130 is buckled with the upper bottom surface of the drinking water body 110. The sealing member 120 is provided on the lower bottom surface of the inner plug flip cover 130.

[0047] A connecting shaft 140 is provided at the hinged joint between the inner plug flip cover 130 and the upper bottom surface of the drinking body 110, so that the sealing member 120 can be rotated around the connecting shaft 140 along with the inner plug flip cover 130 to enable the sealing member 120 to be inserted and removed from the lower drinking spout 112. The connecting shaft 140 can be made of stainless steel.

[0048] refer to Figure 2 The inner plug flip cover 130 is hinged to the upper bottom surface of the drinking body 110, and it and the cup spout 114 are located on opposite sides of the upper drinking port 111. The upper bottom surface of the upper drinking port 111 is raised to form a connecting block 113a. The connecting block 113a and the cup spout 114 are located on opposite sides of the upper drinking port 111, making rational use of the space layout to prevent interference between the seal 120 and the drinking water. The connecting block 113a is provided with a through hole 113a1. When the inner plug flip cover 130 is clamped on both sides of the connecting block 113a, the connecting shaft 140 passes through the inner plug flip cover 130 and the through hole 113a1 on the connecting block 113a, allowing the inner plug flip cover 130 to rotate about the axis of the connecting shaft 140.

[0049] refer to Figure 1 、 Figure 2 、 Figure 5 The connection between the inner plug flip cover 130 and the drinking body 110 is located outside the connecting rib 113b. By pressing a button on the inner plug flip cover 130, the connection is released. The sealing member 120 rotates from left to right along with the inner plug flip cover 130 around the axis of the connecting shaft 140, thereby opening the lower drinking spout 112. When the sealing member 120 rotates from right to left along with the inner plug flip cover 130 around the axis of the connecting shaft 140 until the inner plug flip cover 130 is connected to the drinking body 110, the sealing member 120 closes the lower drinking spout 112.

[0050] Preferably, the hinged joint between the inner plug flip cover 130 and the drinking body 110 is located on the side of the sealing member 120 away from the air guide groove 112a. This allows for quick ventilation when the inner plug flip cover 130 is flipped over and the lower drinking spout 112 is opened, allowing for quick opening of the inner plug flip cover 130.

[0051] like Figure 1 As shown, the lower surface of the inner plug flap 130 is provided with a raised structure 131. The seal 120 and the raised structure 131 have an interference fit, which enhances the connection strength and prevents loosening. For example, the raised structure 131 has a plurality of holes, and the inner wall of the upper end of the seal 120 is embedded in these holes, and the fit between the two is an interference fit.

[0052] In summary, by providing the air guide groove 112a, air can be ventilated by slightly loosening the seal 120, thereby balancing the air pressure inside and outside the cup body 200, thereby achieving the purpose of making the seal 120 easy to pull out and not being sucked.

[0053] Second embodiment

[0054] like Figure 1 and Figure 4 As shown, the cup includes the cup inner plug 100 of the first embodiment, and the cup also includes:

[0055] A cup body 200 having a port 210 , wherein the lower portion of the drinking body 110 of the cup plug 100 is inserted into the port 210 of the cup body 200 ;

[0056] The cup cover 300 is screwed to the outer wall of the port 210 of the cup body 200 , and the cup cover 300 covers the cup inner plug 100 .

[0057] Since the cup includes the cup inner plug 100 of the first embodiment, the beneficial effects of the cup can refer to the cup inner plug 100 .

[0058] The cup is used as follows:

[0059] The cup cover 300 is removed.

[0060] The button on the inner plug flip cover 130 of the cup inner plug 100 is pressed to release the buckle connection between the inner plug flip cover 130 and the drinking water body 110 .

[0061] The inner plug flip cover 130 is rotated from left to right around the axis of the connecting shaft 140, so that the sealing member 120 is separated from the lower drinking spout 112 as the inner plug flip cover 130 rotates. During this process, due to the presence of the air guide groove 112a, the sealing member 120 is slightly loosened to allow air to flow and balance the air pressure inside and outside the cup body 200, thereby allowing the sealing member 120 to be pulled out from the lower drinking spout 112.

[0062] After the user aligns his mouth with the cup spout 114 and pours the cup body 200 , the liquid in the cup body 200 passes through the lower drinking port 112 and the cup spout 114 into the user's mouth.

[0063] Finally, the inner plug flip cover 130 is rotated around the axis of the connecting shaft 140 and flipped from right to left until the inner plug flip cover 130 is buckled with the drinking body 110. The sealing member 120 is then plugged with the lower drinking port 112. The cup cover 300 covers the cup inner plug 100 and is screwed to the port 210 of the cup body 200.

[0064] It should be noted that when the inner plug flip cover 130 is buckled with the drinking body 110, the inner plug flip cover 130 cannot be turned over, and the sealing member 120 is always in a state of plugging the lower drinking port 112 to prevent the sealing member 120 from being pulled out at will.

[0065] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
