[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a manual shut-off valve, including a manual shut-off valve body 1; a protective shell 11 is provided on the side wall of the manual shut-off valve body 1; a drive motor 12 is fixedly connected to the inner side wall of the protective shell 11; a fan blade 13 is fixedly connected to the output end of the drive motor 12; a heating wire 14 is fixedly connected to the inner side wall of the protective shell 11; a pair of guide pipes 15 are fixedly connected to the side wall of the protective shell 11; the guide pipes 15 are symmetrically arranged on both sides of the protective shell 11 and have the same structure; a guide plate 16 is fixedly connected to the end of the guide pipe 15; in use, by starting the drive motor 12, the drive motor 12 drives the fan blade 13 to rotate and generate airflow, blowing air towards the manual shut-off valve body 1. At this time, the airflow will pass through the heating wire 14, which can heat the passing airflow. Finally, when passing through the guide plate 16, the airflow is heated by the guide plate 16. The flow plate 16 can guide and disperse the airflow, while some of the airflow will enter the guide pipe 15. The guide pipe 15 is used to guide the airflow and blow it onto the manual shut-off valve body 1 on the side away from the protective shell 11. This will dry the moisture adhering to the surface of the manual shut-off valve body 1. The protective shell 11 can protect the drive motor 12 during use and prevent foreign objects from contacting it. In this process, it plays a drying role when the manual shut-off valve body 1 is used in a humid environment, reducing the corrosion caused by prolonged moisture adhesion and thus improving the service life of the manual shut-off valve body 1. At the same time, the guide pipe 15 and the flow plate 16 can increase the contact area between the airflow and the manual shut-off valve body 1, increase the drying speed, and the protective shell 11 can also increase the safety of the drive motor 12 during use.

[0025] Furthermore, such as Figures 1-4As shown, a pair of mounting blocks 2 are fixedly connected to the side wall of the manual shut-off valve body 1; the mounting blocks 2 are symmetrically arranged on both sides of the manual shut-off valve body 1 and have the same structure; the side wall of the mounting block 2 has an insertion hole 21; a pair of fixing posts 22 are fixedly connected to the side wall of the protective shell 11; the fixing posts 22 are symmetrically arranged on both sides of the protective shell 11 and have the same structure; the fixing posts 22 and the insertion holes 21 are in sliding fit; multiple elastic plates 23 are evenly fixed to the side wall of the fixing posts 22; in use, by holding the protective shell 11, the fixing posts 22 are inserted into the side wall of the insertion holes 21, and the inclined surfaces of the elastic plates 23 can be used to... The fixing post 22 moves toward the center of the insertion hole 21. At the same time, the elastic plate 23 is squeezed by the wall of the mounting block 2 and moves toward the side wall of the fixing post 22. After the elastic plate 23 passes through the insertion hole 21, it can automatically reset and abut against the side wall of the mounting block 2, thus fixing the protective shell 11. This process facilitates the installation and disassembly of the protective shell 11, making it easier to disassemble and collect. This increases the flexibility and practicality of the protective shell 11 during use. The elastic plate 23 can also limit the insertion of the fixing post 22 into the side wall of the insertion hole 21.

[0026] Furthermore, such as Figures 1-4 As shown, the side wall of the fixed post 22 has a groove 3; a spring rod 31 is fixedly connected to the side wall of the groove 3; a pressing rod 32 is fixedly connected to the end of the spring rod 31; a connecting rope 33 is fixedly connected between the pressing rod 32 and the elastic plate 23; the connecting rope 33 passes through the wall of the fixed post 22 and is slidably connected to it; in use, by directly pressing the pressing rod 32, as the pressing rod 32 moves into the groove 3, the connecting rope 33 can be pulled to move, and the connecting rope 33 can be used to pull the surrounding elastic plates 23 closer, and then the fixed post 22 can be pulled out from the side wall of the insertion hole 21. After use, the pressing rod 32 can be released directly. At this time, the elasticity of the spring rod 31 can push the pressing rod 32 to reset. In this process, it facilitates the simultaneous operation of the surrounding elastic plates 23, improves the disassembly speed of the protective shell 11, reduces the workload caused by the difficulty in operating multiple elastic plates 23, and further increases the practicality of the protective shell 11 in use.

[0027] Furthermore, such as Figures 1-4As shown, a filter screen plate 4 is fixedly connected to the side wall of the protective shell 11; a rotating rod 41 is rotatably connected to the side wall of the filter screen plate 4; a pair of cleaning brushes 42 are fixedly connected to the side wall of the rotating rod 41; the cleaning brushes 42 are symmetrically arranged on both sides of the rotating rod 41 and have the same structure; in use, when the airflow enters the protective shell 11, it will pass through the filter screen plate 4. The filter screen plate 4 can filter and block the dust contained in the airflow. At the same time, the rotating rod 41 can be held and rotated to make the cleaning brushes 42 clean the side wall of the filter screen plate 4, sweeping away the dust attached to the surface of the filter screen plate 4. In this process, it plays the filtering role of the fan blade 13 when drawing air, reducing the adhesion of dust on the surface of the manual shut-off valve body 1, thereby increasing the cleanliness of the surface of the manual shut-off valve body 1. At the same time, the cleaning brushes 42 can clean the surface of the filter screen plate 4, which can increase the anti-clogging effect of the filter screen plate 4 during use and improve the airflow.

[0028] Furthermore, such as Figures 1-4 As shown, a pair of elastic rods 5 are fixedly connected to the side wall of the filter screen plate 4; the elastic rods 5 are symmetrically arranged on both sides of the filter screen plate 4 and have the same structure; an elastic ball 51 is fixedly connected to the end of the elastic rod 5; in use, when the cleaning brush 42 rotates, the cleaning brush 42 will collide with the elastic ball 51, and the elastic ball 51 can knock the cleaning brush 42. Then, the elasticity of the elastic rod 5 can drive the elastic ball 51 to reset. At this time, the vibration effect of knocking can shake off the dust attached to the surface of the cleaning brush 42. In this process, it plays a role in cleaning the dust attached to the surface of the cleaning brush 42, reducing the accumulation of dust on the surface of the cleaning brush 42, thereby increasing the subsequent cleaning effect of the cleaning brush 42.

[0029] Furthermore, such as Figures 1-4 As shown, an elastic sheet 6 is fixed to the side wall of the cleaning brush 42. When in use, when the elastic ball 51 hits the wall of the cleaning brush 42, the elasticity of the elastic sheet 6 can generate resonance, which increases the vibration effect. In this process, the vibration effect of the elastic ball 51 when it hits is increased, which further improves the cleaning effect on the surface of the cleaning brush 42, thereby increasing the cleaning effect of the cleaning brush 42 on the surface of the filter screen plate 4.

[0030] Working principle: During use, the drive motor 12 is started, which drives the fan blade 13 to rotate and generate airflow. This airflow blows towards the manual shut-off valve body 1. The airflow passes through the heating wire 14, which heats the airflow. Finally, when it passes through the guide plate 16, the guide plate 16 guides and disperses the airflow. At the same time, some airflow enters the guide pipe 15, which guides the airflow towards the manual shut-off valve body 1 on the side away from the protective shell 11. This removes the air adhering to the manual shut-off valve body 1. The surface moisture is dried by the air, and the protective shell 11 protects the drive motor 12 during use, preventing foreign objects from contacting it. During use, by holding the protective shell 11, the fixing post 22 is inserted into the side wall of the insertion hole 21. The inclined surface of the elastic plate 23 allows the fixing post 22 to move towards the center of the insertion hole 21. Simultaneously, the elastic plate 23 is pressed against the side wall of the mounting block 2 by the wall of the mounting block 2. After the elastic plate 23 passes through the insertion hole 21, its elasticity allows it to automatically reset and press against the side wall of the mounting block 2, thus securing the protective shell 11 in place. By directly pressing the pressing rod 32, as the pressing rod 32 moves into the groove 3, the connecting rope 33 can be pulled to move. The connecting rope 33 can pull the surrounding elastic plates 23 closer, and then the fixing post 22 can be pulled out from the side wall of the insertion hole 21. After use, the pressing rod 32 can be released directly. At this time, the elasticity of the spring rod 31 can push the pressing rod 32 to return to its original position. During use, when the airflow enters the protective shell 11, it will pass through the filter plate 4. The filter plate 4 can filter and block the dust contained in the airflow. At the same time, the rotating rod 41 can be held and rotated. The cleaning brush 42 moves to clean the side wall of the filter screen plate 4, removing the dust attached to the surface of the filter screen plate 4. When the cleaning brush 42 rotates, it will collide with the elastic ball 51. The elastic ball 51 can knock the cleaning brush 42. Then, the elasticity of the elastic rod 5 can drive the elastic ball 51 to reset. At this time, the vibration effect of the knock can shake off the dust attached to the surface of the cleaning brush 42. When the elastic ball 51 hits the wall of the cleaning brush 42, the elasticity of the elastic sheet 6 can generate resonance, which increases the vibration effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
