Description

Technical Field

[0001] This utility model relates to the field of straw technology, and in particular to a straw. Background Technology

[0002] In beverage consumption scenarios, straws, as a common auxiliary tool, are widely used in the drinking process of various beverages. Existing straws are typically structurally optimized for a single beverage type or drinking need. For example, straws for hot drinks (such as hot coffee) often use narrow diameters or multi-hole diversion structures to slow the flow rate and prevent burns from excessively fast flow. However, this design can affect the drinking experience when drinking room temperature or cold beverages due to the limited flow rate. Conversely, large-diameter straws suitable for room temperature or cold beverages, while allowing for rapid drinking, cannot effectively control the flow rate when handling hot beverages, posing a safety hazard.

[0003] As consumers increasingly demand higher standards for beverage drinking experience and safety, traditional single-function straws can no longer meet diverse usage needs. Although some multi-functional straws exist on the market, most achieve function switching through complex detachable structures or additional accessories. This not only increases the production cost and usage complexity of straws but also leads to problems such as missing parts and inconvenient cleaning, making it difficult to balance practicality and convenience. Therefore, there is an urgent need to design a straw with a simple structure that can flexibly adjust the flow channel structure according to the beverage temperature to meet different drinking needs. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a straw that can flexibly adjust the flow channel structure according to the temperature of the beverage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A straw includes a linearly extending elastic circular tube, a partition strip and a slot disposed within the elastic circular tube and extending along the length of the elastic circular tube. When the cross-section of the elastic circular tube is circular, the partition strip and the slot separate, forming a single flow channel within the elastic circular tube. When the cross-section of the elastic circular tube is flattened, the partition strip is fitted into the slot, forming a double flow channel within the elastic circular tube.

[0007] As a further improvement to the above technical solution, the slot is formed by two protrusions raised from the inner wall of the elastic cylindrical tube, and the shape of the slot is adapted to the shape of the partition strip.

[0008] As a further improvement to the above technical solution, two symmetrically arranged clamping hooks are formed on the top of the protruding strip, and a locking position is formed on the partition strip to cooperate with the clamping hooks.

[0009] As a further improvement to the above technical solution, the corners of the clamping hook are rounded.

[0010] As a further improvement to the above technical solution, the two lower corners of the partition strip are chamfered.

[0011] As a further improvement to the above technical solution, the two channels in the dual-channel system are arranged symmetrically from left to right and are separated by partition strips.

[0012] As a further improvement to the above technical solution, the elastic circular tube is a silicone tube.

[0013] The beneficial effects of this invention: The straw provided by this invention breaks through the limitations of traditional single-function straws. Through a simple structural design, it achieves the function of flexibly adjusting the flow channel structure according to the temperature of the beverage. Whether it is for quick drinking of room temperature or cold drinks, or for safe and slow drinking of hot drinks, a simple operation of squeezing the round tube body is all it takes to make the divider strip snap into the slot to form a dual-flow channel. There is no need to replace the straw or use additional accessories, which greatly satisfies consumers' diverse needs for different drinking experiences and safety. Attached Figure Description

[0017] This utility model provides a straw. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0018] Please see Figure 1 and Figure 2This utility model provides a straw, including a linearly extending elastic circular tube 1, a partition strip 2 and a groove 3 disposed inside the elastic circular tube 1 and extending along the length direction of the elastic circular tube 1. When the cross-section of the elastic circular tube 1 is circular, the partition strip 2 and the groove 3 separate, so that a single flow channel 11 is formed inside the elastic circular tube 1; when the cross-section of the elastic circular tube 1 is flat and round, the partition strip 2 is adapted to be inserted into the groove 3, so that a double flow channel 12 is formed inside the elastic circular tube 1.

[0019] When a user takes a straw to drink a room temperature or cold beverage, the flexible cylindrical tube 1 is in its natural state with a circular cross-section. At this time, the partition strip 2 and the slot 3 are separated from each other, and a single, continuous large-diameter flow channel is formed inside the entire flexible cylindrical tube 1. The large diameter of the flow channel ensures that the beverage flows through at a relatively fast speed, thereby meeting the user's need to quickly drink room temperature or cold beverages.

[0020] When using a straw to drink hot beverages, the user can apply external force with their hand to gently squeeze the elastic cylindrical tube 1. Due to the elasticity of the tube, its cross-section gradually changes from a circle to a flattened circle under the action of external force. During this deformation process, the relative position of the partition strip 2 and the slot 3 changes, and the partition strip 2 precisely fits into the slot 3, dividing the originally single large-diameter flow channel into two independent small flow channels. Compared to the single flow channel 11, the dual flow channel 12 structure reduces the cross-sectional area of ​​the beverage flow, effectively slowing down the flow rate of hot beverages, preventing users from being scalded due to excessively fast flow, achieving control over the flow rate of hot beverages, and also helping to dissipate heat quickly and lower the drinking temperature of hot beverages.

[0021] This invention provides a straw that breaks through the limitations of traditional single-function straws. Through a simple structural design, it achieves the function of flexibly adjusting the flow channel structure according to the temperature of the beverage. Whether for quick drinking of room temperature or cold drinks, or for safe and slow drinking of hot drinks, a simple operation of squeezing the round tube body allows the divider strip to engage in the slot, creating a dual-flow channel. No straw replacement or additional accessories are required, greatly satisfying consumers' diverse needs for different drinking experiences and safety. Furthermore, this straw is reusable. Due to its simple structure, cleaning the straw only requires rinsing with water to easily clean the inside, avoiding cleaning dead spots caused by complex structures and effectively ensuring the straw's cleanliness and hygiene.

[0022] Specifically, the slot 3 is formed by two protruding strips 31 protruding from the inner wall of the elastic cylindrical body 1. This structural design allows the slot 3 and the elastic cylindrical body 1 to form an integrated connection, which can better withstand the pressure generated by external extrusion and beverage flow, effectively preventing problems such as loosening or falling off during use. Since the shape of the slot 3 matches the shape of the partition strip 2, when the cross-section of the elastic cylindrical body 1 becomes flat and round, the partition strip 2 can fit tightly into the slot 3, greatly reducing the possibility of beverage leakage from the engagement point. This not only ensures the beverage diversion effect under the dual-channel 12 structure, but also prevents beverage spillage due to leakage, improving user experience and safety.

[0023] In a preferred embodiment, two symmetrically arranged clamping hooks 32 are formed on the top of the protrusion 31, and locking positions 21 that cooperate with the clamping hooks 32 are formed on the partition strip 2. The clamping hooks 32 can be embedded into the locking positions 21, which greatly increases the contact area and friction between the partition strip 2 and the slot 3, making the two lock more tightly and effectively preventing the partition strip 2 from accidentally disengaging from the slot 3. Compared with ordinary adapter structures, it can more effectively prevent beverages from leaking from the locking point, further optimize the sealing performance of the dual flow channel 12, and ensure the stability and reliability of flow rate control when drinking hot beverages.

[0024] The two channels in the dual-channel 12 are arranged symmetrically from left to right and separated by the partition strip 2. This symmetrical structure can reduce turbulence and resistance differences during fluid flow, avoid uneven flow rate caused by channel asymmetry, and ensure that the flow rate of hot beverages is stable and controllable when passing through the dual-channel 12. It can effectively slow down the flow rate to prevent scalding and ensure the smoothness of the drinking process.

[0025] In this embodiment, the elastic cylindrical tube 1 is a silicone tube. The silicone tube possesses excellent elasticity, allowing it to easily deform from a circular shape to a flattened shape when squeezed by the user, thus driving the partition strip 2 and the slot 3 to cooperate and complete the flow channel switching. When force is applied to separate the partition strip 2 and the slot 3, it can quickly return to its original shape, ensuring the straw can be reused multiple times with stable performance, effectively extending the straw's lifespan. Compared to other materials, it is better suited to frequent flow channel switching operations.

[0026] In addition, silicone has a wide temperature resistance range, capable of withstanding the high temperatures of hot beverages (such as hot coffee and hot tea) without deforming, melting, or releasing harmful components, while also adapting to the low temperatures of cold beverages, maintaining structural stability and elasticity. This ensures that the straw functions properly in both single-channel (11) and dual-channel (12) applications for beverages at different temperatures, broadening the straw's applicability. The smooth surface of silicone does not easily absorb stains and odors; cleaning simply requires rinsing with water or using simple cleaning tools to quickly remove residual beverages, and it is not prone to bacterial growth.
