Description

Technical Field

[0001] This utility model relates to the field of daily necessities, and in particular to a lightweight thermos cup with an integrated structure and a filtration function. Background Technology

[0002] With the diversification of user needs, insulated cups with filtering functions are gradually gaining popularity. They achieve functions such as tea-water separation and fruit particle filtering through built-in or external filter components, meeting the usage needs in scenarios such as tea brewing and beverage preparation. However, the design of existing filtering functions still has significant limitations and urgently needs technological improvement.

[0003] Currently, most mainstream insulated water bottles with filters on the market use an independent funnel structure to achieve their filtration function. This funnel is typically a plate-shaped or cone-shaped component with filter holes, fixed to the inner wall or outer rim of the cup via a physical locking mechanism. In use, the user needs to manually press the funnel into the cup rim, using the friction of the rim's edge for temporary fixation, then pour in the materials to be filtered, such as tea leaves or fruit pieces, and finally add the liquid to complete the brewing process. While this design fulfills basic filtration needs, its fixing method and user experience have significant shortcomings.

[0004] The stability of existing funnel-type filter structures is highly dependent on the force of manual clamping. If the clamping is insufficient, the funnel is prone to displacement or even detachment during water diversion due to liquid impact, cup tilting, or shaking, leading to filtration failure, contamination of the beverage, or accidental funnel fall. This problem not only affects ease of use but also poses a risk of burns due to a detached funnel. Furthermore, repeated disassembly and reassembly of the funnel can cause wear on the cup rim, further reducing the reliability of the fixation. Therefore, improving the installation stability and safety of the filter assembly has become crucial for optimizing the filtration function of insulated cups. Utility Model Content

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] This embodiment mainly describes the structure of the thermos cup, as follows: A lightweight, integrated thermos with a filter function, such as Figures 1-5 As shown, the device includes a thermos cup 1, a lid 101, a mounting ring 2, a thread 3, a filter screen 4, a fixing rod 5, and an adjusting screw 6. The lid 101 is located on the top of the thermos cup 1. The thread 3 is located on the inner side of the mouth of the thermos cup 1 and on the outer side of the mounting ring 2. The thermos cup 1 and the mounting ring 2 are fastened together by the thread 3. The vertical fixing rod 5 is connected inside the mounting ring 2, and the adjusting screw 6 is rotatably connected inside the mounting ring 2. The filter screen 4 is slidably connected inside the mounting ring 2. One end of the filter screen 4 is slidably connected to the fixing rod 5, and the other end is connected to the thread 3 of the adjusting screw 6. The fixing rod 5 and the adjusting screw 6 are symmetrically arranged about the mounting ring 2, which ensures that the filter screen 4 can be raised and lowered smoothly.

[0021] like Figure 3As shown, it also includes an operation plate 7 and a reset spring 8. The operation plate 7 is slidably connected to the top of the adjusting screw 6 in a vertical direction. The reset spring 8 is provided in the adjusting screw 6 in a vertical direction. The upper end of the reset spring 8 is connected to the bottom of the operation plate 7, and the bottom of the reset spring 8 is connected to the adjusting screw 6. The top of the operation plate 7 is pressed against the inner side of the cup lid 101.

[0022] like Figure 4 As shown, it also includes a sealing gasket 9. The sealing gasket 9 is connected to the outer ring of the bottom of the mounting ring 2. The sealing gasket 9 is squeezed and fitted with the inner side of the thermos cup 1. The sealing gasket 9 is made of flexible silicone material. It fills the connection gap between the mounting ring 2 and the thermos cup 1 by compression deformation, effectively preventing liquid leakage.

[0023] like Figure 4 As shown, it also includes a flow guide ring 11, which is connected inside the thermos cup 1. The flow guide ring 11 is provided with a slope with the same thickness as the mounting ring 2 to ensure a smooth transition of the liquid flow path. The equal-thickness slope design of the flow guide ring 11 can reduce liquid residue and improve cleaning convenience.

[0024] like Figure 4 As shown, it also includes a spring pad 10, which is connected to the bottom of the mounting ring 2. The spring pad 10 is pressed and engaged with the guide ring 11.

[0025] like Figure 2 As shown, it also includes protrusions 12. Several protrusions 12 are connected around the top of the inner ring of the mounting ring 2. The surface of the protrusions 12 is provided with anti-slip texture to enhance hand friction, making it easier for users to hold the mounting ring 2 for rotation operation and improving disassembly and assembly efficiency.

[0026] like Figure 5 As shown, it also includes a cover ring 13, which is slidably connected to the mouth of the thermos cup 1, and a plurality of protrusions 12 are arranged around the inner side of the cover ring 13.

[0027] like Figure 2 As shown, it also includes a scale ring 14. The fixed rod 5 is provided with a number of scale rings 14 at intervals. The scale rings 14 are used to mark the capacity corresponding to the height of the filter screen 4, which can intuitively quantify the height of the filter screen 4 and meet the brewing needs of different capacities.

[0028] When the filtration function is not needed, the user can insert the cover ring 13 into the mouth of the thermos cup 1. At this time, the outer edge of the cover ring 13 forms a sealing fit with the inner wall of the thermos cup 1, and its bottom fits against the top surface of the guide ring 11, effectively sealing the gap of the thread 3 between the thermos cup 1 and the mounting ring 2, preventing liquid from seeping into the groove of the thread 3 and remaining. If the filtration function needs to be activated, the user needs to pinch the protrusion 12 on the inner wall of the cover ring 13 with his / her hand, squeeze it slightly to deform the outer edge of the cover ring 13 slightly, and then rotate the cover ring 13 while pulling it upward. The friction between the protrusion 12 and the mouth of the thermos cup 1 will gradually disengage the cover ring 13, and finally the cover ring 13 can be completely removed.

[0029] When installing the filter 4, the user holds the protrusion 12 on the outer wall of the mounting ring 2, aligns it with the thread 3 groove at the mouth of the thermos cup 1, and rotates it clockwise. Through the interlocking action of the thread 3 pair, the mounting ring 2 is gradually screwed into the thermos cup 1. The sealing gasket 9 on the bottom outer ring of the mounting ring 2 always maintains sliding contact with the inner wall of the thermos cup 1, which scrapes away the residual liquid adhering to the inner wall. When the mounting ring 2 is tightened, the spring pad 10 at its bottom is deformed by the pressure of the bottom of the thermos cup 1, further filling the tiny gap between the mounting ring 2 and the guide ring 11, expelling residual water while enhancing the overall sealing. If the height of the filter screen 4 needs to be adjusted, the user can rotate the operating plate 7. The operating plate 7 rotates through the sliding cooperation with the adjusting screw 6, thereby driving the filter screen 4 to move up and down along the guide groove on the inner wall of the mounting ring 2. The other end of the filter screen 4 slides synchronously along the guide structure of the fixing rod 5. The height of the filter screen 4 can be intuitively judged by the scale rings 14 spaced apart on the surface of the fixing rod 5, meeting the brewing needs of different capacities.

[0030] When the cup lid 101 is closed, the user aligns the cup lid 101 with the mouth of the thermos 1 and presses it down. The protruding structure on the inner side of the cup lid 101 presses against the top surface of the operating plate 7, forcing the operating plate 7 to slide downward along the axis of the adjusting screw 6. At the same time, it compresses the return spring 8 inside the adjusting screw 6 to store energy. When the cup lid 101 is fully closed, the operating plate 7 is completely hidden inside the adjusting screw 6, avoiding the operation plate 7 protruding and affecting the sealing effect between the cup lid 101 and the thermos 1. When drinking water, the user opens the cup lid 101. The previously compressed return spring 8 pushes the operating plate 7 to slide upward and reset. At this time, when pouring liquid, the filter screen 4 effectively intercepts impurities such as tea leaves and fruit particles. After the water flows through the inclined structure of the guide ring 11, it flows out along the inner wall of the thermos 1, avoiding direct impact on the flat surface at the bottom of the mounting ring 2, which would cause liquid splashing and ensure a smooth and splash-free pouring process.
