Description

Technical Field

[0001] This utility model belongs to the field of drinking water cups, and in particular relates to a water cup with a dual filtration structure. Background Technology

[0002] As a container specifically designed for holding liquids, water cups with filtration functions are becoming increasingly widely used in daily life as people become more aware of healthy drinking water.

[0003] Currently, the filtration structure used in water filter cups on the market is usually a filter screen or filter cartridge set at the mouth of the cup. Generally, the filter screen used for brewing tea has a relatively large pore size, which allows tea water to seep out, but cannot intercept fine coffee powder. On the other hand, the filter screen used for brewing coffee has a very small pore size, which can block coffee powder, but it is very easy to be blocked by tea leaves when used for brewing tea, affecting the seepage of tea water.

[0004] In summary, if the filter mesh has too large a pore size, fine particles cannot be effectively intercepted, affecting the filtration effect; if the pore size is too small, it is easily clogged by large particles, reducing the water flow rate. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a water cup with a dual filtration structure, which aims to solve the problems of easy clogging of the mesh, poor flowability, and incomplete filtration in the prior art.

[0006] This utility model embodiment is implemented as follows: the water cup with the dual filtration structure includes: a cup body, a cup lid, and a filter assembly; The cup body is a hollow cylindrical structure with an opening at the top, used to contain liquid; The cup lid is connected to the opening at the top of the cup body; The filter assembly includes an upper filter assembly and a lower filter assembly.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 The diagram shown is a structural diagram of a water cup with a dual filtration structure provided in an embodiment of the present invention, including: a cup body, a cup lid, and a filtration assembly; The cup body is a hollow cylindrical structure with an opening at the top, used to contain liquid; The cup lid is connected to the opening at the top of the cup body; The filter assembly includes an upper filter assembly and a lower filter assembly. The upper filter assembly is detachably installed at the connection between the cup lid and the cup body. The lower filter assembly is detachably installed in the middle of the cup body. The filter pore sizes of the upper filter assembly and the lower filter assembly are different.

[0019] In this embodiment of the invention, the cup body is a hollow cylindrical structure with an opening at the top, which is used to hold drinking water, tea or other liquids; the cup body is made of titanium metal.

[0020] The cup lid is sealed to the opening at the top of the cup body by screwing or snapping to prevent liquid leakage and make it easy to carry.

[0021] The upper filter assembly is a detachable structure, specifically installed at the connection between the lid and the body of the cup. The upper filter assembly can be a ring-shaped filter screen, with its outer edge fixed to the inside of the opening in the cup body, located below the lid. When the user unscrews the lid to drink, the liquid passes through the upper filter assembly, which intercepts larger suspended particles such as tea leaves and fruit pieces.

[0022] The lower filter assembly is also a detachable structure, installed in the middle of the cup body. The lower filter assembly can be a bowl-shaped filter screen or filter basket, with a different pore size than the upper filter assembly, suitable for intercepting fine suspended matter.

[0023] In one embodiment of this invention, there are two brewing methods for tea. One method involves placing the tea leaves between the upper and lower filter components, then pouring in an appropriate amount of hot water and covering the cup. In this case, the tea leaves are confined to the area between the upper and lower filter components. When drinking, the upper filter removes larger tea leaves, while the lower filter traps finer tea hairs, preventing them from entering the mouth and affecting the taste.

[0024] Secondly, the upper filter component can be used independently. Simply put the tea leaves directly into the upper filter component, pour in hot water to brew, and then remove the upper filter component directly. This effectively separates the tea leaves from the tea soup, preventing the tea from becoming too strong due to prolonged steeping. Users can flexibly choose the method of use according to their own preference for the strength of the tea.

[0025] When using it to brew coffee, the bottom filter can be used independently. Place the coffee grounds in the bottom filter and then pour hot water into the cup. The small pores of the bottom filter effectively trap the coffee grounds, allowing the extracted coffee liquid to collect at the bottom of the cup. The bottom filter can also be removed directly to separate the coffee grounds.

[0026] In one embodiment of this utility model, after use, the filter components can be disassembled for individual cleaning, making it easy to thoroughly clean every corner inside the water cup and maintain its hygiene.

[0027] This utility model provides a water cup with a dual-filtration structure. By setting up upper and lower filter components with different pore sizes, users can selectively install and combine them according to the beverage being brewed, such as tea or coffee powder. For example, when brewing tea, the upper filter component with a suitable pore size can be used alone or in combination with the lower filter component to effectively intercept tea leaves while ensuring a smooth flow of tea soup; when brewing coffee, the lower filter component can be used alone to effectively block fine coffee powder. This method improves the water cup's adaptability to different beverages and the filtration quality.

[0028] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the upper filter assembly includes a filter support and a first filter screen; The filter support has a ring structure with a boss at the top. The outer diameter of the boss is smaller than the inner diameter of the opening at the top of the cup body. A sealing ring that seals with the cup body is provided in the middle of the filter support. At least two L-shaped slots distributed along the axial direction of the filter support are also provided at the bottom of the filter support. The first filter screen has a hollow cylindrical structure with multiple filter holes on its side walls and bottom; the top side of the first filter screen has buckles that protrude inwards, the same number as the L-shaped slots, and the buckles are used to cooperate with the L-shaped slots on the filter screen support.

[0029] In this embodiment of the utility model, the filter support and the cup lid are either integrally formed or separate structures; When the filter holder and the cup lid are integrally molded, they are made of the same material using a one-piece molding process. This structure eliminates any seams between the filter holder and the cup lid, resulting in high overall strength and reducing the likelihood of breakage or loosening. It also simplifies the assembly process. During installation, simply screw the cup lid onto the cup body; there is no need to install the filter holder separately, enhancing user convenience.

[0030] When the filter holder and lid are separate components, the assembly process is relatively flexible. Insert the filter holder through the top opening of the cup body, allowing it to fall under its own weight until it overlaps the top port of the cup body. At this point, the filter holder is supported at the step at the top of the cup body, while the first filter screen hangs inside the cup body. Then, screw the lid into the upper cup body; the bottom edge of the lid contacts the upper surface of the filter holder and applies downward pressure, pressing the filter holder between the step at the top port of the cup body and the bottom of the lid, preventing it from shaking, tilting, or shifting inside the cup body.

[0031] In one embodiment of this invention, the first filter screen is made of titanium or stainless steel. When installing the first filter screen, align the clips on the first filter screen with the L-shaped groove at the bottom of the filter screen bracket, then push the first filter screen upwards so that the clips move along the vertical part of the L-shaped groove to the top. Next, rotate the first filter screen so that the clips enter the horizontal part of the L-shaped groove, thereby securely installing the first filter screen onto the filter screen bracket. This installation method is simple to operate and ensures the stability of the connection between the first filter screen and the filter screen bracket.

[0032] like Figure 1 As shown in the preferred embodiment of this utility model, the cup body includes an upper cup body and a lower cup body; the lower filter assembly is detachably installed at the connection between the upper cup body and the lower cup body, the lower filter assembly has a bowl-shaped structure, and its side walls and bottom are provided with multiple filter holes; the top opening of the lower filter assembly is provided with an outwardly extending annular flange, the annular flange is used to place the lower filter assembly at the connection between the upper cup body and the lower cup body, the top of the lower filter assembly fits against the bottom of the upper cup body, thereby achieving a tight connection between the two and preventing the lower filter assembly from shaking or shifting.

[0033] In this embodiment of the utility model, the cup body is either an integral structure or a split structure; When the cup body is a detachable structure, it consists of an upper cup body and a lower cup body. The upper cup body and the lower cup body can be detachably assembled together by means of threads, snaps, or other conventional connections.

[0034] The lower filter assembly has a bowl-shaped structure and is detachably installed at the connection between the upper and lower cup bodies. Multiple filter holes are evenly distributed on the side walls and bottom of the lower filter assembly. During installation, the lower filter assembly is inserted through the top opening of the lower cup body, allowing it to fall under its own weight until the annular flange overlaps the top port of the lower cup body. At this point, the annular flange is supported at the step at the top of the lower cup body, and the main body of the lower filter assembly hangs inside the lower cup body. Then, the upper cup body is screwed into the lower cup body; the bottom edge of the upper cup body contacts the upper surface of the annular flange and applies downward pressure, pressing the annular flange between the top port step of the lower cup body and the bottom of the upper cup body. This effectively prevents it from shaking, tilting, or shifting inside the cup body.

[0035] When the cup body is a single piece, an annular support platform is provided inside for installing the lower filter assembly. This support platform is arranged circumferentially along the inner wall of the cup, and its height is located at the middle of the cup body. The lower filter assembly also has a bowl-shaped structure, with its top side wall extending outward to form an annular flange. During installation, the lower filter assembly is inserted through the top opening of the cup body, allowing it to fall under its own weight until the annular flange overlaps the annular support platform. At this point, the main body of the lower filter assembly hangs in the lower space inside the cup body.

[0036] like Figure 1 As shown, in a preferred embodiment of the present invention, the cup body includes an upper cup body and a lower cup body; the upper cup body and the lower cup body, and the upper cup body and the cup lid are connected by threads; and sealing gaskets for preventing leakage are provided on the contact surfaces of the upper cup body and the lower cup body, and the upper cup body and the cup lid.

[0037] In this embodiment of the utility model, in order to ensure the sealing of the connection and prevent liquid leakage, a first sealing gasket is provided at the threaded end face of the connection between the upper cup body and the lower cup body; when the upper and lower cup bodies are tightened, the gasket is compressed, effectively preventing it from leaking out from the threaded connection.

[0038] A second sealing gasket is provided between the top port of the upper cup body and the stepped surface inside the cup lid; when the cup lid is tightened, the gasket is compressed, which can effectively prevent the liquid inside the cup from overflowing from the connection between the cup lid and the upper cup body.

[0039] The first and second sealing gaskets are made of high-quality sealing materials with good corrosion resistance and anti-aging properties. In addition, the sealing gaskets can also act as a buffer to reduce rigid collisions that may occur during the tightening process of the cup body and avoid damage to the threads.

[0040] like Figure 1As shown in the preferred embodiment of this utility model, the lower cup body is a hollow columnar structure with a closed bottom, and its top is provided with an opening for connection with the upper cup body. The opening is provided with a thread for connection with the upper cup body.

[0041] In this embodiment of the invention, the hollow portion of the lower cup body is used to store liquid, and the thread at the opening of the lower cup body is adapted to the thread of the upper cup body to achieve a tight connection; the side wall of the lower cup body is provided with a textured anti-slip structure to increase the friction when the user holds the lower cup body and prevent the cup from slipping due to sweaty hands or water stains; the bottom of the lower cup body is also provided with anti-slip texture to improve the stability of placement.

[0042] like Figure 1 As shown in the preferred embodiment of this utility model, the upper cup body is a hollow columnar structure with a ring at its top. The inner arm of the top of the ring is provided with a thread for connecting with the cup lid. The connection between the ring and the upper cup body is provided with a protrusion for placing the upper filter assembly. The bottom edge of the upper cup body is provided with a thread for connecting with the lower cup body.

[0043] In this embodiment of the invention, the upper cup body is a hollow cylindrical shell with an integrally formed ring at its top. The inner wall of the top of the ring is machined with an internal thread for connecting the cup lid. The connection between the ring and the upper cup body is provided with an inwardly protruding structure. This protruding structure surrounds the inner wall of the upper cup body to form a stepped support surface. The support surface is used to place the upper filter assembly, which is placed to fall downwards during the brewing process. The outer wall of the bottom edge of the upper cup body is provided with an external thread for connecting the lower shell, thereby combining the upper cup body and the lower cup body to form a complete container.

[0044] like Figure 3 As shown in a preferred embodiment of the present invention, the water cup with the dual filtration structure is also equipped with a thermometer; The thermometer includes a dial and a temperature measuring component; the dial is located on the top of the cup lid and is used to display the water temperature inside the cup; the temperature measuring component passes through the cup lid, the filter frame, and the first filter screen and is used to detect the water temperature inside the cup.

[0045] In this embodiment of the invention, the user can understand the water temperature inside the cup without opening the lid or using external tools; the dial uses a digital or pointer display method, which makes it convenient for the user to quickly obtain water temperature information; the temperature measuring component is a slender temperature measuring probe, the top of which is connected to the dial; a first sealing ring is provided at the protrusion of the cup lid to prevent water vapor from leaking from the interface; a corresponding through hole is provided at the center of the filter frame for the temperature measuring component to pass through; the end of the temperature measuring component protrudes from the center of the bottom of the first filter screen, and a second sealing ring is provided at this through hole for sealing and fixing.

[0046] If the temperature measuring component is a mechanical thermometer, the temperature-sensing medium expands when heated, pushing the pointer to rotate on the dial to indicate the current water temperature; if it is an electronic thermometer, the temperature sensor transmits the signal to the dial, and the LCD screen displays the specific temperature value.

[0047] like Figure 3 As shown, in a preferred embodiment of the present invention, a drinking cup is also provided above the cup lid; a plurality of magnets are installed on the top of the cup lid and distributed along the axial direction of the cup lid, and a magnetic block adapted to the magnets is installed at the corresponding position on the bottom of the drinking cup.

[0048] In this embodiment of the invention, the drinking cup is an independent container with a smaller capacity than the main body, generally used to pour tea from the main body into the drinking cup for drinking. Through the distribution of multiple magnets, the connection can resist a certain degree of lateral shaking and torsion, ensuring that the drinking cup on top will not easily fall off; when it needs to be used separately, only a certain pulling or torsional force needs to be applied to easily separate the two, achieving easy assembly and disassembly.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
