[0021] 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.

[0022] Example 1

[0023] Please see Figures 1-5 The present invention provides the following technical solution: a novel detachable filter straw, including a straw 1, a mounting base 2 fixedly connected to the lower part of the straw 1, a filter nozzle 3 threadedly connected to the lower part of the mounting base 2, a filter screen 4 placed inside the filter nozzle 3, a straw 2 5 installed above the straw 1, a suction nozzle 7 fixedly connected above the straw 2 5, an anti-backflow component 6 installed between the straw 1 and the straw 2 5, and a protective component 8 sleeved on the top of the suction nozzle 7.

[0024] Specifically, the anti-backflow assembly 6 includes an anti-backflow seat 61, a support seat 62, a sealing ball 63, a mesh plate 64, and an installation assembly 65. The anti-backflow seat 61 is installed between the first straw 1 and the second straw 5. The installation assembly 65 is provided at both ends of the anti-backflow seat 61. The support seat 62 is fixedly connected to the lower part of the inside of the anti-backflow seat 61. The sealing ball 63 abuts against the upper part of the support seat 62. The mesh plate 64 is fixedly connected to the upper part of the inside of the anti-backflow seat 61.

[0025] By adopting the above technical solution, when in use, suction is generated, which moves the sealing ball 63 in the anti-backflow seat 61, causing the sealing ball 63 and the support seat 62 to separate. Water then flows through the gap between them and out through the mesh plate 64. When suction is not applied, the sealing ball 63 automatically falls back and fits tightly against the support seat 62 to prevent water from flowing back from above.

[0026] Specifically, the mounting component 65 includes an internal thread seat 651, an external thread seat 652, an external thread seat 653, and an internal thread seat 654. The internal thread seat 651 is fixedly connected to the lower part of the anti-backflow seat 61. The internal thread of the internal thread seat 651 is connected to the external thread seat 652, and the lower part of the external thread seat 652 is fixedly connected to the suction tube 1. The external thread seat 653 is fixedly connected to the upper part of the anti-backflow seat 61. The internal thread seat 654 is connected to the surface of the external thread seat 653, and the upper part of the internal thread seat 654 is fixedly connected to the suction tube 2 5.

[0027] By adopting the above technical solution, the anti-backflow seat 61 and the suction tube 1 can be easily spliced ​​by the internal thread seat 651 and the external thread seat 652, and the anti-backflow seat 61 and the suction tube 2 can be easily spliced ​​by the external thread seat 653 and the internal thread seat 654.

[0028] Specifically, guide sliders 66 are fixedly connected to both sides of the sealing ball 63, and the anti-backflow seat 61 has a guide groove inside that matches the sealing ball 63.

[0029] By adopting the above technical solution, the guide slider 66 and the guide groove cooperate to facilitate the stable sliding of the sealing ball 63, thereby preventing left and right wobbling.

[0030] In this embodiment, during use, suction is generated, which moves the sealing ball 63 within the anti-backflow seat 61, causing the sealing ball 63 to separate from the support seat 62. Water then flows through the gap between them and out through the mesh plate 64. When suction ceases, the sealing ball 63 automatically falls back and fits tightly against the support seat 62, preventing water from flowing back. The internal thread seat 651 and external thread seat 652 facilitate the connection between the anti-backflow seat 61 and the suction tube 1. Similarly, the external thread seat 653 and internal thread seat 654 facilitate the connection between the anti-backflow seat 61 and the suction tube 5. This design prevents the sucked-out water from flowing back during use, thus preventing water backflow contamination and improving practicality.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the protective component 8 includes a support block 81, a rubber sleeve 82, a rubber connecting rod 83, and a protective cover 84. The support block 81 is fixedly connected to the surface of one upper end of the straw 5. The rubber sleeve 82 is abutted against the upper part of the support block 81, and the rubber sleeve 82 and the straw 5 are tightly fitted together. The rubber connecting rod 83 is fixedly connected to one side of the rubber sleeve 82. The protective cover 84 is fixedly connected to the end of the rubber connecting rod 83 away from the rubber sleeve 82, and the protective cover 84 and the nozzle 7 are tightly fitted together.

[0033] By adopting the above technical solution, the rubber sleeve 82 is tightly fitted onto the straw 5, and the support block 81 facilitates the limitation of the fitting range of the rubber sleeve 82, thereby completing the installation of the protective cover 84, which can then be used. When in use, the protective cover 84 is simply fitted onto the suction nozzle 7, thus facilitating the protection of the suction nozzle 7 when it is no longer in use.

[0034] Specifically, the inner wall of the protective cover 84 is fixedly connected with anti-slip texture 85.

[0035] By adopting the above technical solution, the anti-slip texture 85 facilitates the improvement of the stability of the connection between the protective cover 84 and the nozzle 7.

[0036] In this embodiment, when in use: the rubber sleeve 82 is tightly fitted onto the second straw 5, and the support block 81 facilitates the limitation of the fitting range of the rubber sleeve 82, thereby completing the installation of the protective cover 84, which can then be used. When in use, the protective cover 84 is simply fitted onto the suction nozzle 7, thereby facilitating the protection of the suction nozzle 7 when it is no longer in use. This allows the device to protect the suction head during use, preventing the suction nozzle 7 from being exposed to the outside world and contaminated.

[0037] The structure and working principle of the filter screen 4 in this utility model have been disclosed in a filter straw disclosed in Chinese patent application number 202121420060.0. Its working principle is that the filter screen 4 facilitates the filtration of water.

[0038] The working principle and usage process of this utility model are as follows: In use, the filter screen 4 facilitates water filtration, and the suction tube allows for easy removal, cleaning, and replacement of the filter screen 4. The anti-backflow component 6 prevents water backflow and contamination. The protective component 8 protects the suction nozzle 7. When in use, the anti-backflow component 6 generates suction, moving the sealing ball 63 within the anti-backflow seat 61, separating the sealing ball 63 from the support seat 62. Water then flows through the gap between them, through the mesh plate 64, and out. When suction is stopped, the sealing ball 63 automatically falls back and tightly adheres to the support seat 62, preventing water backflow. The internal threaded seat 651 and external threaded seat 652 facilitate the adjustment of the anti-backflow seat 6. The device is spliced ​​with the straw 1 using the external threaded seat 653 and the internal threaded seat 654, which facilitates the splicing of the anti-backflow seat 61 and the straw 5. This prevents the sucked water from flowing back during use, thus preventing water backflow contamination and improving the practicality of use. When using the protective component 8, the rubber sleeve 82 is tightly fitted onto the straw 5, and the support block 81 facilitates the limitation of the fitting range of the rubber sleeve 82, thereby completing the installation of the protective cover 84. After that, it can be used. When in use, the protective cover 84 is simply fitted onto the suction nozzle 7, which facilitates the protection of the suction nozzle 7 when it is no longer in use. This allows the device to protect the suction head during use, preventing the suction nozzle 7 from being exposed to the outside world and contaminated.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
