Description

Technical Field

[0001] This utility model belongs to the technical field of straw caps, specifically relating to a multifunctional plastic water cup straw cap with adjustable flow rate. Background Technology

[0002] The existing straw cup lid mainly consists of three parts: a bottom cover, a top cover, and an upper straw. The bottom cover and the top cover are hinged together by a hinge structure, and the bottom cover and the top cover are locked and unlocked by a latch. The bottom cover is provided with an upper straw hole, a pressure relief hole, and an upper straw gate. The top cover is provided with a pressure relief hole plug and an upper straw gate seal. The upper straw is inserted into the upper straw hole. The water in the cup can be drunk through the upper straw. The pressure relief hole is used to add air into the cup when drinking to maintain a constant pressure in the cup with atmospheric pressure. When the top cover is used to seal the bottom cover, the upper straw gate seal presses the upper straw tightly against the upper straw gate, sealing the outlet of the upper straw. The pressure relief hole plug is inserted into the pressure relief hole to seal the pressure relief hole.

[0003] For certain groups, such as the elderly, children, or people with health conditions, drinking too quickly may cause choking. The flow rate adjustment function can help them control their drinking speed and reduce the risk of choking, while the existing straw cap does not have the function of adjusting the flow rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional plastic water cup straw cap with adjustable flow rate.

[0005] To achieve the above objectives, this utility model provides a multifunctional plastic water cup straw cap with adjustable flow rate, including a cap body, a flip cover rotatably connected to the cap body, a fastener provided on one side of the cap body, an inner cavity fixedly connected inside the cap body, an upper straw inserted and fixedly connected inside the inner cavity, a reinforcing part fixedly connected inside the inner cavity and communicating with the upper straw, a lower straw fixedly connected to the bottom of the reinforcing part, and a flow rate adjustment component provided in the inner cavity;

[0006] The flow regulating component is used to regulate the flow rate of the upper straw.

[0007] In the above technical solution, the flow regulating component further includes a transmission rod rotatably connected to the inner cavity, a cam rotatably connected to the transmission rod, a protrusion fixedly connected to one side of the cover, a first gear and a second gear rotatably connected to the protrusion from top to bottom via a shaft, the second gear being connected to the transmission rod, the first gear and the second gear meshing with each other, an insert block fixedly connected to the first gear, the insert block penetrating the protrusion and rotatably connected, an insert rod inserted and slidably connected to the insert block, and an adjustment key fixedly connected to one end of the insert rod.

[0008] In the above technical solution, further, the outer wall of the insert block is symmetrically provided with protruding holes, a movable plate corresponding to the insert block is slidably connected inside the insert block, a vertical plate is slidably connected to the bottom of the movable plate and the vertical plate is fixed to the inner wall of the insert block, a guide rod is fixedly connected to the upper part of the movable plate and is inserted through the vertical plate and slidably connected, a spring is sleeved on the outside of the guide rod, a cone block is fixedly connected to the other end of the insert rod, a lever block is fixedly connected to one side of the movable plate, magnetic mating blocks are symmetrically arranged on the outer wall of the insert block, and magnetic blocks are symmetrically fixed on the adjustment key, and the magnetic blocks and magnetic mating blocks correspond to each other.

[0009] In the above technical solution, the lever is further configured as an elastic structure.

[0010] In the above technical solution, a weakening band is further provided on the reinforced part.

[0011] In the above technical solution, the number of teeth of the first gear is greater than the number of teeth of the second gear.

[0012] In the above technical solution, the top of the movable plate is further configured as a wedge shape.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The weakening band is more flexible than the reinforcing section and has stronger deformation and tensile properties, effectively reducing the force required for the user to turn the cam. Turning the adjustment key drives the transmission rod to rotate, ultimately rotating the cam. The protrusion on the cam gradually contacts the weakening band and compresses its outer wall, causing deformation. As the weakening band deforms internally, the channel for liquid flow narrows, thus adjusting the liquid flow rate. Through the transmission of several gears, a locking force is achieved, maintaining pressure on the weakening band and preventing rebound. Simultaneously, the torque is converted through the first and second gears, enabling more precise control of the cam's rotation, resulting in finer flow control. With this design, precise flow adjustment can be achieved simply by turning the adjustment key. The structure is simple and durable, with a locking effect that effectively maintains pressure on the weakening band. Furthermore, when the cam rotates to a certain extent, it causes the weakening band to adhere to the inner wall of the reinforcing section, achieving a sealing effect, preventing moisture loss, and extending the insulation time. It offers multiple functions.

[0015] By connecting the plug rod, pressing the adjustment key can cause the cone block to squeeze the moving plate and move the moving plate to one side, thereby pushing the dial block out of the plug block. At this time, the magnetic block attracts the magnetic mating block to maintain the position of the cone block. The flow rate can then be adjusted by flicking the dial block with your finger. The above structure provides a second flow rate adjustment method for users to choose from, which can effectively avoid user hand fatigue. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-5The multi-functional plastic water cup straw cap with adjustable flow rate shown includes a cap body 1, a flip cover 2 rotatably connected to the cap body 1, a fastener 3 on one side of the cap body 1, an inner cavity 4 fixedly connected inside the cap body 1, an upper straw 5 inserted and fixedly connected inside the inner cavity 4, a reinforcing part 18 fixedly connected inside the inner cavity 4 and communicating with the upper straw 5, a lower straw 25 fixedly connected to the bottom of the reinforcing part 18, and a flow rate adjustment component for adjusting the flow rate of the upper straw 5. The flow rate adjustment component includes a transmission rod 17 rotatably connected inside the inner cavity 4. A cam 16 is rotatably connected to rod 17. A protrusion 6 is fixedly connected to one side of cover 1. A first gear 14 and a second gear 19 are inserted and rotatably connected from top to bottom through a shaft inside the protrusion 6. The second gear 19 is connected to the transmission rod 17. The first gear 14 and the second gear 19 mesh with each other. A plug 7 is fixedly connected to the first gear 14. The plug 7 passes through the protrusion 6 and is rotatably connected. A plug rod 8 is inserted and slidably connected to the plug 7. An adjusting key 9 is fixedly connected to one end of the plug rod 8. The first gear 14 has more teeth than the second gear 19. (Reinforcement part) A weakening band 15 is provided on 18. The weakening band 15 is more flexible than the reinforcing part 5 and has stronger deformation and tensile properties. It can effectively reduce the force required for the user to turn the cam 16. When the user turns the adjustment key 9, it will drive the transmission rod 17 to rotate, which will eventually drive the cam 16 to rotate. The protrusion on the cam 16 gradually contacts the weakening band 15 and compresses its outer wall, causing it to deform. When the inside of the weakening band 15 is deformed, the channel for liquid flow will narrow, thus adjusting the liquid flow rate accordingly. Through the transmission of several gears, it has a certain locking force, which can maintain the weakening band. The pressure of cam 15 prevents it from rebounding. At the same time, the torque is converted through the first gear 14 and the second gear 19 to achieve more precise control over the rotation of cam 16, thereby achieving more refined flow control. With the above design, the flow rate can be precisely adjusted by simply turning the adjustment key 9. The structure is simple and durable, and has a locking effect, which can effectively maintain the pressure on the weakening band 15. At the same time, when cam 16 rotates to a certain extent, it will cause the weakening band to adhere to the inner wall of the reinforcing part 15, thereby achieving a sealing effect, preventing water vapor from escaping, extending the heat preservation time, and having a multi-functional effect.

[0024] Symmetrical protrusion holes 12 are provided on the outer wall of the insertion block 7. A movable plate 21 corresponding to the insertion block 7 is slidably connected inside the insertion block 7. A vertical plate 22 is slidably connected to the bottom of the movable plate 21 and is fixed to the inner wall of the insertion block 7. A guide rod 23 is fixedly connected to the upper part of the movable plate 21 and passes through the vertical plate 22 and is slidably connected. A spring 24 is sleeved on the outside of the guide rod 23. A cone block 20 is fixedly connected to the other end of the insertion rod 8. A lever block 13 is fixedly connected to one side of the movable plate 21. Magnetic mating blocks 11 are symmetrically arranged on the outer wall of the insertion block 7. The adjustment key 9 is... A magnetic block 10 is fixed in place, and the magnetic block 10 corresponds to the magnetic mating block 11. Through the connection of the plug rod 8, pressing the adjustment key 9 can cause the cone block 20 to squeeze the moving plate 21 and move the moving plate 21 to one side, thereby pushing the lever 13 out of the plug block 7. At this time, the magnetic block 10 attracts the magnetic mating block 11 and keeps the position of the cone block 20. The flow rate can be adjusted by flicking the lever 13 with a finger. The above structure provides a second flow rate adjustment method for users to choose from, which can effectively avoid user hand fatigue.

[0025] The lever 13 is designed as an elastic structure. With this design, the lever 13 can be stored inside the protrusion 6 by bending, thereby avoiding motion interference when the excessively long lever 13 enters the protrusion 6.

[0026] The top of the movable plate 21 is designed with a wedge shape. This design makes it easier for its wedge surface to fit into the cone block 20, making the transmission effect of the cone block 20 more obvious.

[0027] Working principle:

[0028] The weakening band 15 is more flexible than the reinforcing part 5, and has stronger deformation and tensile properties. It can effectively reduce the force required for the user to twist the cam 16. When the user twists the adjustment key 9, it drives the transmission rod 17 to rotate, which in turn drives the cam 16 to rotate. The protrusion on the cam 16 gradually contacts the weakening band 15 and compresses its outer wall, causing it to deform. When the interior of the weakening band 15 is deformed, the channel for liquid flow narrows, thus adjusting the liquid flow rate accordingly. Furthermore, through the transmission of several gears, it has a certain locking force, which can maintain pressure on the weakening band 15. To prevent rebound, and with the torque converted through the first gear 14 and the second gear 19, more precise control of the rotation of the cam 16 is achieved, thereby enabling more refined flow control. With the above design, precise flow adjustment can be achieved simply by turning the adjustment key 9. The structure is simple and durable, with a locking effect, which can effectively maintain the pressure on the weakening band 15. At the same time, when the cam 16 rotates to a certain extent, it will cause the weakening band to adhere to the inner wall of the reinforcing part 15, thereby achieving a sealing effect, preventing water vapor from escaping, extending the heat preservation time, and having multiple functions.

[0029] By connecting the plug rod 8, pressing the adjustment key 9 can cause the cone block 20 to press against the moving plate 21 and move the moving plate 21 to one side, thereby pushing the lever 13 out of the plug block 7. At this time, the magnetic block 10 attracts the magnetic mating block 11 to maintain the position of the cone block 20. The flow rate can be adjusted by flicking the lever 13 with your finger. The above structure provides a second flow rate adjustment method for users to choose from, which can effectively avoid user hand fatigue.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
