Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermos cup technology, and in particular to a car thermos cup with a rotating filter structure. Background Technology
[0002] With the continuous growth in car ownership and the increasing demand for long-distance travel, insulated car bottles, as key devices for ensuring the quality of beverages during journeys, are experiencing a surge in market demand. Users not only require long-lasting heat retention but also expect precise solid-liquid separation when brewing tea, fruit tea, or coffee. This makes filtration a crucial indicator of the practicality of insulated car bottles, placing higher demands on the flexibility and adaptability of the filtration structure.
[0003] The most common car thermos cup filter structure on the market is a fixed filter screen design. This type of structure usually fixes the filter screen to the inside of the cup lid or the bottom of the tea strainer by welding, nesting or threading. Once the filter screen pore size is formed, it cannot be changed. Its working principle is to use the liquid to flow into the cup body through the filter screen pores under the action of pouring or siphoning, while solids such as tea leaves and fruit pieces are intercepted because their size is larger than the mesh.
[0004] Existing car thermos cups with fixed filter structures cannot flexibly adapt to the different filtration precision requirements of various beverages. When users use fine-pore filters to brew fruit tea, larger fruit pieces and petals easily accumulate and clog the mesh, causing the liquid to flow slowly or even not be poured out. When switching to coarse-pore filters to brew fine tea leaves or coffee powder, it is difficult to effectively intercept impurities, resulting in a cloudy taste. Frequently changing filters of different pore sizes is not only cumbersome, but also prone to losing parts in the shaking environment of a car, affecting the user experience. Therefore, a car thermos cup with a rotating filter structure is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a car thermos cup with a rotating filter structure, aiming to improve the problem that the existing technology cannot flexibly adapt to the different filtration accuracy requirements of different beverages, thus affecting the user experience.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A car thermos cup with a rotating filter structure includes a cup body, a cup lid threadedly connected to the side wall of the cup body, a tea strainer threadedly connected inside the cup lid, and an adjustment component provided inside the tea strainer;
[0008] The adjustment component includes a rotating frame, the side wall of which is rotatably connected to the inside of the tea strainer. A filter screen is fixedly connected inside the rotating frame, and a mounting base is fixedly connected inside the rotating frame. A spring is fixedly connected to the side wall of the mounting base, and a locking block is fixedly connected to one end of the spring.
[0009] As a further description of the above technical solution:
[0010] A limiting ring is fixedly connected to the side wall of the rotating frame, and the side wall of the limiting ring is rotatably connected inside the tea strainer.
[0011] As a further description of the above technical solution:
[0012] The limiting ring is used to limit the axial displacement of the rotating frame, preventing the rotating frame from wobbling up and down or detaching from the tea strainer during rotation.
[0013] As a further description of the above technical solution:
[0014] The internal holes of the tea strainer are the same as the holes of the filter screen, and the tea strainer has multiple fixing grooves inside.
[0015] As a further description of the above technical solution:
[0016] The fixed grooves, from left to right, correspond to three modes: coarse pore filtration, fine pore filtration, and completely closed, to meet different filtration needs.
[0017] As a further description of the above technical solution:
[0018] The sidewall of the card block is slidably connected inside the rotating frame, and the sidewall of the card block is slidably connected inside the fixing groove.
[0019] This utility model has the following beneficial effects:
[0020] In this invention, by rotating the rotating frame, the locking block slides within the rotating frame. The tea infuser has multiple fixing slots inside, corresponding to three states: coarse pore filtration, fine pore filtration, and fully closed. When the rotating frame rotates to the appropriate filtration mode position, the locking block engages with the corresponding fixing slot under the elastic force of spring one, thus fixing the position of the rotating frame and determining the state of the filter. This solves the problem that some car thermos cup filters cannot flexibly adapt to the different filtration precision requirements of different beverages, affecting the user experience. The above structure improves the practicality of the device. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0030] Reference Figures 1-6 The present invention provides an embodiment of a car thermos cup with a rotating filter structure, comprising a cup body 1, a cup lid 2 threadedly connected to the side wall of the cup body 1, a tea strainer 3 threadedly connected inside the cup lid 2, and an adjustment component inside the tea strainer 3. The cup body 1 is used to hold beverages, serving to store liquids and maintain temperature, thus realizing the basic functions of a thermos cup. The cup lid 2 is threadedly connected to the side wall of the cup body 1 to seal the cup body 1, preventing beverages from spilling and heat loss. The tea strainer 3 is used to hold solid beverage ingredients such as tea leaves and fruit pieces, preventing solids from directly entering the cup and affecting drinking.
[0031] The adjusting assembly includes a rotating frame 4, whose sidewall is rotatably connected to the inside of a tea strainer 3. A filter screen 5 is fixedly connected inside the rotating frame 4 to intercept solid impurities such as tea leaves and fruit particles, achieving solid-liquid separation. A mounting base 7 is fixedly connected inside the rotating frame 4, and a spring 8 is fixedly connected to the sidewall of the mounting base 7. A locking block 9 is fixedly connected to one end of the spring 8, providing elasticity to the locking block 9 and fixing the position of the rotating frame 4. A limiting ring 6 is fixedly connected to the sidewall of the rotating frame 4, rotatably connected to the inside of the tea strainer 3, and used to limit the axial movement of the rotating frame 4. The displacement mechanism prevents the rotating frame 4 from wobbling up and down or detaching from the tea strainer 3 during rotation. The internal holes of the tea strainer 3 are consistent with the holes of the filter screen 5, facilitating accurate switching of the filtration mode when the filter screen 5 rotates. The tea strainer 3 has multiple fixing slots inside, which correspond to three modes from left to right: coarse pore filtration, fine pore filtration, and fully closed filtration, to meet different filtration needs. Users can flexibly adjust according to the type of beverage. The locking block 9 cooperates with the fixing slots, and under the elastic force of the spring 8, it achieves precise positioning of the rotating frame 4 in different filtration modes, achieving a reliable and stable filtration effect.
[0032] Working principle: When using this thermos, three fixing grooves are opened along the circumference of the inner wall of the tea infuser 3, corresponding to three modes from left to right: coarse pore filtration, fine pore filtration, and completely closed. When the rotating frame 4 rotates, the locking block 9 slides along the inner wall of the rotating frame 4 under the action of centrifugal force and is locked into the corresponding fixing groove under the action of the spring 8. When the locking block 9 is locked into the leftmost fixing groove, the large-diameter area of the filter screen 5 is completely aligned with the holes of the tea infuser 3, which is suitable for filtering large particles such as fruit pieces. The rotating frame 4 rotates clockwise until the locking block 9 is locked into the middle fixing groove. At this time, the fine area of the filter screen 5 coincides with the holes of the tea infuser 3, which can intercept small particles such as tea leaves and coffee grounds. Continue to rotate until the locking block 9 is locked into the rightmost fixing groove. The solid part of the filter screen 5 completely covers the holes of the tea infuser 3, realizing unfiltered direct drinking or heat preservation function. The limiting ring 6 on the side wall of the rotating frame 4 is embedded in the annular groove on the inner wall of the tea infuser 3 to ensure axial stability during the rotation process.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
