Technical Field

[0001] This utility model relates to a straw assembly with a filter and a water cup containing the same. Background Technology

[0002] Water cups with detachable straw components on the market require the straw component to be removed from the cup before water can be poured in. After pouring, the straw component must be put back into the cup. Furthermore, the straw component needs to be held in hand or placed on the countertop after being removed during the pouring process, which is inconvenient and takes up countertop space.

[0003] Furthermore, existing straw assemblies only have the single function of being used as straws; when open, the drinking part of the straw is generally upright or at a fixed angle, requiring the cup to be rotated to a specific angle or tilted to drink, making drinking inconvenient; in addition, existing straw assemblies have a relatively complex structure and are inconvenient to assemble. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a straw assembly with a filter screen that is simple in structure, easy to use and assemble, and has multiple functions, as well as a water cup containing the same assembly.

[0005] This utility model is achieved through the following technical solution: A straw assembly with a filter screen includes a filter screen with an opening at the bottom and a downwardly extending mounting sleeve. A guide tube is provided in the inner hole of the mounting sleeve, with the bottom end of the guide tube extending downward from the bottom of the mounting sleeve. A suction nozzle is rotatably connected to the top end of the guide tube, and the suction nozzle is exposed above the filter screen. An adjustable angle is formed between the suction nozzle and the filter screen. The internal channels of the guide tube and the suction nozzle are connected to form a water outlet channel.

[0008] As a preferred embodiment of the above-mentioned straw assembly with filter screen, the top of the tube is detachably connected to a cap, the lower section of the central hole of the cap and the inner cavity of the top of the tube together form a spherical cavity, and the upper section of the central hole of the cap is a frustum-shaped structure that is larger at the top and smaller at the bottom.

[0009] As a preferred embodiment of the above-mentioned straw assembly with filter screen, the internal channel of the conduit is connected to the spherical cavity by a transition channel, which is shaped like a frustum with a larger upper section and a smaller lower section.

[0010] As a preferred embodiment of the above-mentioned straw assembly with filter screen, the guide tube is provided with a limiting structure that limits the upper limit position of the guide tube's upward movement.

[0011] As a preferred embodiment of the above-mentioned straw assembly with filter screen, the bottom end of the mounting sleeve is provided with opening grooves on both sides, and the opening grooves are connected to the inner hole and bottom hole of the mounting sleeve.

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0025] See Figures 1 to 5 This embodiment discloses a suction tube assembly with a filter screen, including a filter screen 1. The filter screen 1 has an opening at its center bottom and a downwardly extending mounting sleeve 2. The filter screen 1 and the mounting sleeve 2 are integrally formed plastic parts. The inner hole of the mounting sleeve 2 is provided with a guide tube 3 that can elastically extend and retract along the axial direction of the mounting sleeve 2. The bottom end of the guide tube 3 extends downward from the bottom hole 4 on the bottom wall of the inner hole of the mounting sleeve 2 and is detachably connected to a hose 5. The inner hole of the mounting sleeve 2 is provided with an elastic element that always elastically pushes the guide tube 3 upward. The elastic element can be a spring 6 fitted on the lower section of the guide tube 3. The upper and lower ends of the spring 6 elastically press against the stepped surface 7 on the outer wall of the guide tube 3 and the bottom wall surface of the inner hole of the mounting sleeve 2, respectively. The top end of the guide tube 3 is rotatably connected to a suction nozzle 8, which is exposed above the filter screen 1. An adjustable angle is formed between the suction nozzle 8 and the filter screen 1. The bottom of the suction nozzle 8 is spherically hinged to the top of the guide tube 3. The internal channels of the hose 5, the guide tube 3, and the suction nozzle 8 are sequentially connected to form a water outlet channel 9.

[0026] The conduit 3 has an outwardly extending mounting bracket at its top end, and a spherical body 11 at the bottom of the suction nozzle 8. The spherical body 11 at the bottom of the suction nozzle 8 is spherically hinged to the spherical cavity 10 of the mounting bracket at the top of the conduit 3. A groove is formed near the lower end of the spherical cavity 10 at the top of the conduit 3, and a sealing ring 12 is embedded in the groove. The internal channel of the conduit 3 is connected to the spherical cavity 10 via a transition channel 13. The transition channel 13 is a frustum-shaped structure, wider at the top and narrower at the bottom. This design increases the water flow rate, ensuring that the internal channel of the suction nozzle 8 remains largely connected to the transition channel 13 even when tilted, preventing a reduction in water flow due to the tilt of the suction nozzle 8. A cap 14 is detachably connected to the top of the conduit 3. The lower section of the central hole of the cap 14 and the inner cavity at the top of the conduit 3 together form the spherical cavity 10. The upper section of the central hole of the cap 14 is a frustum-shaped structure, wider at the top and narrower at the bottom. This design provides sufficient space for the suction nozzle 8 to rotate. The cap 14 and the top of the guide tube 3 can be detachably connected via a threaded connection. An anti-slip groove 15 can be provided on the outer wall of the cap 14 to facilitate rotation. The cap 14 effectively prevents the spherical body 11 of the nozzle 8 from detaching upwards from the spherical cavity 10, providing excellent restraint and anti-detachment protection for the spherical body 11 of the nozzle 8. After the straw assembly is installed at the mouth of the cup body 24, when it is necessary to remove the entire straw assembly from the cup body 24, the entire straw assembly can be pulled upwards by holding the nozzle 8, ensuring that the nozzle 8 will not fall off during the upward pulling process.

[0027] The conduit 3 is provided with a limiting structure to limit the upper limit position of its upward movement. In this embodiment, the limiting structure is configured as follows: the middle section of the conduit 3 is a guide section 16, and a portion of the outer side wall of the guide section 16 is longitudinally cut to form a straight guide surface 17. The bottom of the two straight guide surfaces 17 of the conduit 3 forms a limiting platform 18. The shape of the bottom hole 4 on the inner wall of the mounting sleeve 2 matches the shape of the guide section 16 of the conduit 3. By the bottom end of the mounting sleeve 2 abutting against the two limiting platforms 18 of the conduit 3, the upper limit position of the upward movement of the conduit 3 is limited. The bottom end of the mounting sleeve 2 has opening slots 19 on both sides, which are connected to the inner hole and the bottom hole 4 of the mounting sleeve 2. The two opening slots 19 at the bottom end of the mounting sleeve 2 allow the bottom end of the mounting sleeve 2 to deform under compression, facilitating the assembly and disassembly of the conduit 3 and the mounting sleeve 2.

[0028] The filter screen 1 has several evenly distributed hook springs 20 along its outer circumference. Each hook spring 20 has a lower limit protrusion 21 protruding outwards at its bottom, and an upper limit protrusion 22 protruding outwards at the top of its outer circumference. The gap between the upper limit protrusion 22 and the lower limit protrusions 21 of each hook spring 20 forms an annular groove 23. This design facilitates detachable installation and removal from the cup body 24.

[0029] This embodiment provides a straw assembly with a filter. During installation, first, the spherical body 11 of the nozzle 8 is placed in the cavity at the top of the guide tube 3. The cap 14 is then passed through the nozzle 8 and tightened onto the top of the guide tube 3, thus installing the nozzle 8 and the guide tube 3. The spring 6 is fitted onto the lower section of the guide tube 3. Then, the guide tube 3 is inserted from top to bottom into the inner hole of the mounting sleeve 2, so that the bottom of the guide tube 3 extends downwards from the bottom hole 4 on the bottom wall of the inner hole of the mounting sleeve 2 until the two limiting brackets 18 of the guide tube 3 extend downwards below the mounting sleeve 2. Finally, a flexible tube 5 is fitted onto the bottom of the guide tube 3. After installation, the spring 6 is in a compressed state, always exerting an upward elastic force on the guide tube 3, keeping the guide tube 3 in its upper limit position and the nozzle 8 in an upward-extending state. This completes the assembly of the straw assembly.

[0030] See Figure 6 and Figure 7 This embodiment also discloses a water cup, including a cup body 24 and a cup lid 25 detachably connected to the cup body 24. The cup lid 25 is threadedly connected to the mouth of the cup body 24. The aforementioned straw assembly with a filter screen is detachably installed in the inner cavity of the mouth of the cup body 24. A ring 26 is provided in the inner cavity of the mouth of the cup body 24, and the ring 26 engages with the annular groove 23.

[0031] The installation method of the straw assembly with filter screen to the cup body 24 opening is as follows: Open the cup lid 25 and insert the assembled straw assembly with filter into the cup body 24 from the opening downwards until the hook springs 20 on the outer circumference of the filter 1 pass over the hook protrusions 26 in the inner cavity of the cup body 24. At this point, the annular groove 23 of the filter 1 engages with the hook protrusions 26 in the inner cavity of the cup body 24. This completes the installation of the straw assembly with filter into the cup body 24.

[0032] When the cup lid 25 is closed, the cup lid 25 presses down on the nozzle 8, causing the nozzle 8, the guide tube 3, and the hose 5 to move down together, the spring 6 is compressed, and the main body of the nozzle 8 retracts into the filter screen 1.

[0033] When the cup lid 25 is opened, the spout 8 is released. Under the elastic force of the spring 6, the tubing 3 moves the spout 8 and the hose 5 upwards until they reach the upper limit position. At this point, the spout 8 is in an upward-extended state, allowing drinking through it. Because of the spherical hinge between the spout 8 and the tubing 3, 360-degree rotation is possible, allowing the drinker to drink from multiple angles without rotating or tilting the cup, making it very convenient.

[0034] This embodiment combines a telescopic straw with a filter 1, integrating both the drinking function of the spout 8 and the filtering function of the filter 1. During use, water can be poured into the cup 24 without removing the straw assembly with the filter from the cup body 24, making operation convenient and quick. Furthermore, the spout 8 is both telescopic and freely rotating, making drinking operation extremely convenient.

[0035] The above are merely preferred embodiments of the present utility model and are 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.
