A multifunctional cup cover

Abstract

This utility model belongs to the field of water cup lid technology, and in particular to a rotary multifunctional water cup lid, including a cup body and a lid body connected to the surface of the cup body. A diaphragm is connected to one side of the lid body, and the lid body is also connected to the surface of the top cover. This device, through the action of the diaphragm and the knob, can balance the pressure difference between the inside and outside of the cup body when there is a pressure difference. This is achieved by the air being balanced through the channel created by rotating the knob and the positioning plate, as well as the deformation of the diaphragm. This makes the pressure difference between the inside and outside of the cup almost balanced, thus preventing hot air from burning the hands or the lid body from being sucked in when separating the cup body and the lid body. This makes the use of the cup more convenient. The diaphragm can be disassembled and installed by simply rotating the top cover and the lid body, making it easy to clean.

Description

Technical Field

[0001] This utility model belongs to the technical field of water cup lids, specifically relating to a rotating multifunctional water cup lid. Background Technology

[0002] A water cup lid refers to the cap on top of a water cup. As a covering for water cups, cup lids come in a variety of designs and functions. Depending on the type and purpose of the water cup, cup lids can vary greatly. The main functions and advantages of cup lids include preventing leaks and spills, keeping the water hot or cold, preventing dust and ensuring hygiene, and facilitating drinking. Cup lids are also made of a variety of materials, including food-grade plastic, stainless steel, silicone, and wood. A water cup lid is an important component that integrates functionality, safety, convenience, and design.

[0003] According to CN222466609U, a rotating multifunctional water cup lid is disclosed. This technology discloses "a cup lid, a tea compartment, and a filter plate. The tea compartment is threadedly connected to the lower side of the cup lid, and a filter plate is installed inside the tea compartment. It also includes a mounting cover and a baffle. The mounting cover is connected to the filter plate, and the baffle is slidably connected to the lower part of the mounting cover. By rotating the rotating plate, the second protrusion is rotated to 180 degrees. The rotation of the second protrusion squeezes the first protrusion, causing the first protrusion to move the baffle along the mounting cover. The baffle moves and disengages from the filter plate. Then, the water cup is inverted, so that the water comes into contact with the tea leaves and slowly steeps them. During the steeping process, larger tea leaves and tea dregs will be steeped. The filter plate and filter screen keep the larger tea leaves and tea dregs in the tea compartment, so that there are no larger tea leaves and tea dregs in the tea water, making it convenient for users to enjoy tea water without tea dregs."

[0004] While the design allows the cup to be inverted, enabling water to come into contact with the tea leaves and slowly steep them, larger tea leaves and tea dregs will emerge during the steeping process. The filter plate and screen keep these larger tea leaves and tea dregs inside the tea container, ensuring that there are no larger tea leaves and tea dregs in the tea, making it convenient for users to enjoy tea without tea dregs, this design may cause some inconvenience when in use. Due to the phenomenon of thermal expansion and contraction of water, hot steam may be emitted when opening, burning hands, or the lid may become stuck and difficult to open, which may cause some inconvenience to users.

[0005] To address the aforementioned issues, this application proposes a rotating multifunctional water cup lid. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a rotary multifunctional water cup lid. Through the action of the diaphragm and the knob, when a pressure difference exists between the inside and outside of the cup, the air is balanced by the channels created by rotating the knob and the positioning plate, as well as the deformation of the diaphragm. This nearly balances the pressure difference between the internal and external spaces, preventing hot air from burning hands or the lid from sticking when separating the cup body and the lid. This makes the cup more convenient to use. Furthermore, the diaphragm can be easily removed and installed by simply rotating the lid and the cup body, allowing for convenient cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotating multifunctional water cup lid, including a cup body and a lid body connected to the surface of the cup body. A diaphragm is connected to one side of the lid body, and the lid body is also connected to the surface of an upper cover. The surface of the upper cover is also rotatably connected to a rotating shaft. A knob and a positioning piece are respectively installed at both ends of the rotating shaft, and an exchange hole is also provided on the surface of the upper cover.

[0008] As a preferred embodiment of the rotating multifunctional water cup lid of this utility model, the lid body and the cup body are threadedly connected, and a waterproof ring is embedded in the surface of the lid body. The waterproof ring is in close contact with the surface of the cup body. The surface of the lid body is also provided with positioning points at equal angles, and the positioning points and the lid body are an integrated structure.

[0009] In a preferred embodiment of the rotating multifunctional water cup lid of this utility model, the positioning point and the surface of the diaphragm are fitted together, and the surface of the diaphragm is provided with a through hole that matches the positioning point. The surface of the lid body is also threadedly connected to the upper cover, and one side surface of the upper cover is fitted together with the diaphragm.

[0010] As a preferred embodiment of the rotating multifunctional water cup lid of this utility model, the diaphragm and the waterproof ring are made of food-grade silicone.

[0011] As a preferred embodiment of the rotating multifunctional water cup lid of this utility model, a positioning groove is also provided on one side of the upper cover. The upper cover is also rotatably connected to the rotating shaft and the knob. A positioning piece is also fixedly connected to one end of the rotating shaft, and through holes with the same position are provided on the surfaces of the positioning piece and the knob.

[0012] In a preferred embodiment of the rotary multifunctional water cup lid of this utility model, the positioning piece and the positioning groove are slidably connected, and the positioning piece is shaped like a body of water. The knob, the positioning piece, and the exchange hole are connected, and the channel formed by the knob, the positioning piece, and the exchange hole is connected to the cavity formed inside the upper cover above the diaphragm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: through the action of the diaphragm and the knob, when there is a pressure difference between the inside and outside of the cup, the air can be balanced through the channel created by rotating the knob and the positioning plate, as well as the deformation of the diaphragm, so that the pressure difference between the inside and outside spaces is almost balanced. This can prevent hot air from burning the hands or the cup lid from being sucked on when separating the cup body and the cup lid body, making the use of the cup body more convenient. The diaphragm can be disassembled and installed by simply rotating the top cover and the cup lid body, making it easy to clean. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 As shown:

[0026] A rotating multi-functional water cup lid includes a cup body 1.

[0027] In this implementation plan: The existing announcement number: CN222466609U discloses a rotating multi-functional water cup lid. This patent discloses a cup lid. The cup lid body 2 in this application adopts the same technical means as the prior art. The technical means will not be described in detail here. For details on the improvement of the prior art, please refer to the disclosed technology below. In order to solve the technical problems existing in the prior art, such as the "when the design is used, due to the phenomenon of thermal expansion and contraction of water, hot air may be emitted when opening, which may burn the hands, or the cup lid may be sucked up and difficult to open, which will cause certain inconvenience to use" in terms of use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, a diaphragm 5 and a knob 8 are added on the basis.

[0028] Furthermore:

[0029] like Figure 1 - Figure 6 As shown:

[0030] In conjunction with the above, it also includes a cup lid body 2 connected to the surface of the cup body 1. A diaphragm 5 is connected to one side of the cup lid body 2. The cup lid body 2 is also connected to the surface of the upper cover 6. The surface of the upper cover 6 is also rotatably connected to the rotating shaft 9. A knob 8 and a positioning piece 10 are respectively installed at both ends of the rotating shaft 9. An exchange hole 11 is also provided on the surface of the upper cover 6.

[0031] In this implementation scheme: by simply rotating the knob 8, the air pressure difference between the inside and outside of the cup body 1 can be kept almost uniform, which can prevent the high-temperature gas from being ejected or the cooled air from sucking the cup lid body 2 and making it difficult to open during use.

[0032] Furthermore:

[0033] In an optional embodiment, the cup lid body 2 and the cup body 1 are threaded together, and a waterproof ring 3 is embedded in the surface of the cup lid body 2. The waterproof ring 3 and the surface of the cup body 1 are fitted together. The surface of the cup lid body 2 is also provided with positioning points 4 at equal angles. The positioning points 4 and the cup lid body 2 are an integrated structure.

[0034] In this embodiment, the cup body 1, the cup lid body 2, and the waterproof ring 3 enable the cup body 1 to be used normally with the correct polarity, while the cup lid body 2 and the positioning point 4 enable the diaphragm 5 to obtain a stable connection space and effectively generate deformation.

[0035] Furthermore:

[0036] In an optional embodiment, the surfaces of the positioning point 4 and the diaphragm 5 are fitted together, and the surface of the diaphragm 5 is provided with a through hole that matches the positioning point 4. The surface of the cup lid body 2 is also threadedly connected to the upper cover 6, and one side surface of the upper cover 6 is fitted together with the diaphragm 5.

[0037] In this embodiment, the connection between the positioning point 4 and the diaphragm 5 enables a stable connection between the diaphragm 5 and the positioning point 4, preventing the diaphragm 5 from slipping off between the cup lid body 2 and the upper cover 6 under the pulling force of air pressure, thus ensuring its stability during deformation.

[0038] Furthermore:

[0039] In an optional embodiment, the diaphragm 5 and the waterproof ring 3 are made of food-grade silicone.

[0040] In this embodiment: the waterproof ring 3 and the diaphragm 5 are items that come into direct or indirect contact with water. The food-grade silicone material can ensure the safety of drinking, and the material can also make the diaphragm 5 have high toughness, so that it can deform under the action of air pressure and reduce the pressure difference between the inside and outside.

[0041] Furthermore:

[0042] In an optional embodiment, a positioning groove 7 is also provided on one side of the upper cover 6. The upper cover 6 is also rotatably connected to the rotating shaft 9 and the knob 8. A positioning piece 10 is also fixedly connected to one end of the rotating shaft 9. The surfaces of the positioning piece 10 and the knob 8 are provided with through holes in the same position.

[0043] In this embodiment: under the action of the positioning groove 7, the positioning piece 10 can obtain a limited and precise movement angle. When the positioning piece 10 moves to the end of the positioning groove 7, the positioning piece 10 can be precisely connected with the exchange hole 11, thereby forming a stable gas channel.

[0044] Furthermore:

[0045] In an optional embodiment, the positioning piece 10 and the positioning groove 7 are slidably connected, and the positioning piece 10 is water-shaped. The knob 8, the positioning piece 10 and the exchange hole 11 are connected, and the channel formed by the knob 8, the positioning piece 10 and the exchange hole 11 is connected to the cavity formed above the diaphragm 5 inside the upper cover 6.

[0046] In this embodiment, the positioning piece 10, the knob 8, and the exchange hole 11 can create a stable connection channel between the inside and outside of the cup body 1, thereby enabling the internal and external air pressures to remain nearly uniform through the formed channel, thus avoiding problems when using the cup body 1.

[0047] The working principle and usage of this utility model are as follows: After pouring hot water into the cup body 1 and tightening the cup lid body 2, a sealed space is formed between the cup body 1, the cup lid body 2, and the waterproof ring 3. The diaphragm 5 tightly pressed by the upper cover 6 also ensures the internal sealing. Two situations may occur when hot water is in the cup body 1: When hot water is poured into the cup body 1, the air inside the cup body 1 is heated and its volume expands rapidly. However, since the inside of the cup body 1 is sealed, the expanding air is trapped inside and cannot escape freely, generating expanding gas. Opening the cup body at this time may cause hot air and water vapor to spray out, potentially burning the hands. Alternatively, when hot water is poured into the cup body 1, due to thermal expansion and contraction, the air inside the cup body 1 and at the opening of the cup body 1 expands due to heat. After maintaining the seal for a period of time, the air and moisture in the cup body 1 drop to room temperature. At this time, the moisture and air inside the cup body 1 contract, and the air pressure inside the cup body 1 decreases. When the cup body 1 is lower than the outside, it will suck the lid body 2 and make it difficult to open. In the above two situations, the user can rotate the knob 8 on the surface of the upper cover 6. The knob 8 will drive the rotating shaft 9 and the positioning piece 10 to move along the positioning groove 7. When the through hole and the exchange hole 11 on the surface of the knob 8 and the positioning piece 10 are aligned, the space inside the cup body 1 and the space outside the cup body 1 are connected through the exchange hole 11. At this time, the diaphragm 5 will expand or sink under the action of hot air. When the diaphragm 5 deforms, the pressure inside the cup body 1 can be almost the same as the pressure outside. When the cup body 1 is opened, the hot air inside will not be ejected or the lid body 2 will be difficult to separate. When the cup body 1 needs to be cleaned, the upper cover 6 and the lid body 2 can be separated by rotating the screw. At this time, the diaphragm 5 is no longer under the pressure of the upper cover 6, and the diaphragm 5 can be easily removed from the positioning point 4, thus realizing convenient cleaning.

[0048] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
