Description

Technical Field

[0001] This utility model relates to the field of blower technology, and in particular to a blower with a plug to prevent accidental opening. Background Technology

[0002] A blower is an industrial cleaning tool primarily used in factories, installation, and maintenance settings to remove dust and impurities from hard-to-reach areas. Blower guns are used to clean narrow crevices, high places, inside pipes, or precision parts that are difficult to reach by hand, such as removing dust, powder, processing debris, and water droplets. They can also be used for air cleaning, drying, and cooling equipment. Blower guns utilize the principle of air amplification to effectively reduce the consumption of compressed air, thereby generating a powerful and precise airflow that drives the surrounding air to work together.

[0003] In existing technology, dust blowers on the market need to be connected to a compressor for use. When the dust blower is turned on, a strong airflow is generated at the outlet. After one use, the dust blower is placed aside to await the next use. During the user's activities, it is inevitable that the handle switch of the dust blower will be touched. This can cause the strong airflow generated after the dust blower is turned on to blow the product unintentionally, causing the product to fall or be damaged. If it is directed at the human body, it may cause damage to the eyes, skin, or respiratory tract. Although separating the dust blower from the compressor can prevent this accident, the assembly and disassembly of the dust blower and the compressor is inconvenient due to the sealing. Moreover, the dust blower is used frequently, and the assembly and disassembly of the dust blower will greatly reduce production efficiency. Therefore, it is necessary to improve the dust blower by introducing a plug-type dust blower to prevent accidental opening and solve the above problems. Utility Model Content

[0004] To overcome the problem that users will inevitably touch the handle switch of the blow gun during their activities, which could not only cause the product to fall or be damaged, but also cause injury to the user.

[0005] The technical solution of this utility model is as follows: a dust blower with a plug to prevent accidental opening, including a dust blower body, a barrel, and a mounting assembly. The mounting assembly is provided at the left end of the dust blower body, and the barrel is fixedly connected to the left end of the dust blower body. The barrel has an internal thread, and a plug body is provided inside the barrel. The plug body has an external thread, and the external thread is threaded into the internal thread. A stop block is fixedly connected to the left end of the plug body, and a first knob is fixedly connected to the left end of the stop block.

[0006] Preferably, a connecting strip is fixedly connected to the left end of the first knob, and an elastic rope is fixedly connected inside the connecting strip. A lower mounting frame is provided on the outside of the barrel, and a semi-circular bracket is fixedly connected to the bottom of the lower mounting frame. The elastic rope is located inside the semi-circular bracket, and a rotating disk is fixedly connected to the outside of the elastic rope. The rotating disk is rotatably connected inside the semi-circular bracket.

[0007] Preferably, the semicircular bracket has a matching groove at the corresponding position of the rotating disk, and the rotating disk rotates within the groove of the semicircular bracket.

[0008] Preferably, the lower mounting frame has a matching through hole at the corresponding position of the gun barrel, and the gun barrel is placed inside the through hole of the lower mounting frame.

[0009] Preferably, the mounting assembly includes a semicircular block, which is fixedly connected to the top of the upper mounting frame. A rotating block is rotatably connected inside the semicircular block. The top of the rotating block is fixedly connected to the upper mounting frame. A second fixing block is fixedly connected to the bottom of the upper mounting frame at the end away from the rotating block. A first fixing block is fixedly connected to the top of the lower mounting frame at the end away from the semicircular block. Threaded rods are provided inside the first and second fixing blocks. Nuts are threadedly connected to the outside of the threaded rods. A second knob is fixedly connected to the top of the threaded rods.

[0010] Preferably, the upper mounting frame has a matching through hole at the corresponding position of the gun barrel, and the gun barrel is placed inside the through hole of the upper mounting frame.

[0011] Preferably, the second fixing block and the first fixing block have matching through holes at corresponding positions of the threaded rod, and the threaded rod is disposed inside the through holes of the second fixing block and the first fixing block.

[0012] The beneficial effects of this utility model are as follows: Since users inevitably touch the handle switch of the blower gun during their activities, by threading the plug body into the inside of the gun barrel using external and internal threads, the plug body is inserted into the gun barrel, preventing the product from falling or being damaged when the user touches the handle switch. This improves the usability of the blower gun, prevents injury to the user, enhances the stability of the blower gun, and improves the practicality of the device. It avoids the problems of not only easily causing the product to fall or be damaged, but also causing injury to the user. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of a dust blower with a plug to prevent accidental opening. It includes a dust blower body 1, a barrel 21, and a mounting assembly. The mounting assembly is located at the left end of the dust blower body 1. The barrel 21 is fixedly connected to the left end of the dust blower body 1. An internal thread 26 is formed inside the barrel 21. A plug body 24 is located inside the barrel 21. An external thread 25 is formed on the outside of the plug body 24. The external thread 25 is threaded into the internal thread 26. A stop block 27 is fixedly connected to the left end of the plug body 24. A first knob 28 is fixedly connected to the left end of the stop block 27. By aligning the plug body 24 with the inside of the barrel 21 and threading the external thread 25 into the internal thread 26, the plug body 24 is inserted into the inside of the barrel 21. To prevent users from accidentally touching the handle switch of the blower body 1, thus avoiding damage to the product, the use of the blower body 1 is improved, preventing injury to the user, enhancing the stability of the blower body 1, and improving the practicality of the device. The mounting assembly involves rotating the upper mounting frame 33 within the semi-circular block 31 via the rotating block 32, causing the through hole inside the upper mounting frame 33 to contact the gun barrel 21. Then, the threaded rod 36 and nut 37 engage to fix the lower mounting frame 22 and the upper mounting frame 33, allowing for convenient adjustment of the fixed position as needed, thus improving usability. A connecting strip 29 is fixedly connected to the left end of the first knob 28, and an elastic rope 210 is fixedly connected inside the connecting strip 29. The barrel 21 is externally mounted with a lower mounting frame 22. A semi-circular bracket 23 is fixedly connected to the bottom of the lower mounting frame 22. An elastic rope 210 is disposed inside the semi-circular bracket 23. A rotating disk 211 is fixedly connected to the outside of the elastic rope 210. The rotating disk 211 is rotatably connected inside the semi-circular bracket 23, so that by rotating the first knob 28, the plug body 24 is inserted into the barrel 21 and its internal threads 26 are threaded together, thus inserting the plug body 24 into the barrel 21. This prevents the user from touching the handle switch of the blower body 1, which could cause the product to fall or be damaged. This improves the usability of the blower body 1, prevents injury to the user, and enhances the stability of the blower body 1 during use. To improve the practicality of the device, a corresponding groove is provided on the semi-circular bracket 23 at the corresponding position of the rotating disk 211. The rotating disk 211 rotates within the groove of the semi-circular bracket 23, limiting the elastic rope 210 through the groove. This prevents the elastic rope 210 from tangling while the first knob 28 is rotated, allowing the elastic rope 210 to rotate within the semi-circular bracket 23 via the rotating disk 211. A corresponding through hole is provided on the lower mounting frame 22 at the corresponding position of the gun barrel 21. The gun barrel 21 is placed inside the through hole of the lower mounting frame 22. By placing the gun barrel 21 inside the lower mounting frame 22 and rotating the upper mounting frame 33 within the semi-circular block 31 via the rotating block 32, the through hole inside the upper mounting frame 33 comes into contact with the gun barrel 21.The threaded rod 36 and nut 37 are threaded together to secure the lower mounting frame 22 and the upper mounting frame 33.

[0021] Please see Figure 2 , Figure 5 In this embodiment, the mounting assembly includes a semicircular block 31, which is fixedly connected to the top of the upper mounting frame 33. A rotating block 32 is rotatably connected inside the semicircular block 31, and the top of the rotating block 32 is fixedly connected to the upper mounting frame 33. A second fixing block 35 is fixedly connected to the bottom of the upper mounting frame 33 at the end away from the rotating block 32. A first fixing block 34 is fixedly connected to the top of the lower mounting frame 22 at the end away from the semicircular block 31. Threaded rods 36 are provided inside the first fixing block 34 and the second fixing block 35. Nuts 37 are threadedly connected to the outside of the threaded rods 36, and a second knob 38 is fixedly connected to the top of the threaded rods 36. The mounting assembly rotates the upper mounting frame 33 inside the semicircular block 31 via the rotating block 32, causing the through hole inside the upper mounting frame 33 to contact the gun barrel 21. Then, the threaded rods 36 and the nut 37 engage in threaded engagement, causing the lower mounting frame 22 and the upper mounting frame 23 to be connected in a tandem. The mounting frame 33 is fixed in place, allowing for easy adjustment of its position as needed, thus improving its usability. The upper mounting frame 33 has a corresponding through hole at the corresponding position of the barrel 21. The barrel 21 is placed inside the through hole of the upper mounting frame 33. By rotating the upper mounting frame 33 inside the semi-circular block 31 via the rotating block 32, the through hole inside the upper mounting frame 33 is brought into contact with the barrel 21, facilitating its fixation. The second fixing block 35 and the first fixing block 34 have corresponding through holes at the corresponding positions of the threaded rod 36. The threaded rod 36 is placed inside the through holes of the second fixing block 35 and the first fixing block 34. By aligning and inserting the threaded rod 36 into the through holes of the second fixing block 35 and the first fixing block 34, and then threading it onto the outside of the threaded rod 36 via the nut 37, the lower mounting frame 22 and the upper mounting frame 33 are fixed to the outside of the barrel 21.

[0022] During operation, the barrel 21 is placed inside the lower mounting frame 22. The upper mounting frame 33 is rotated inside the semi-circular block 31 via the rotating block 32, causing the through hole inside the upper mounting frame 33 to contact the barrel 21. The threaded rod 36 is then inserted into the corresponding through holes of the second fixing block 35 and the first fixing block 34. The nut 37 is then fitted onto the bottom of the threaded rod 36. By rotating the second knob 38, the upper mounting frame 33 and the lower mounting frame 22 are fixed to the outside of the barrel 21, allowing for easy adjustment of the fixed position as needed, thus improving usability. After the lower mounting frame 22 and the upper mounting frame 33 are fixed, they are rotatably connected to the inside of the semi-circular bracket 23 via the rotating disk 211, allowing the elastic rope 210 to pass through. The plug body 24, equipped with the first knob 28 and the stop block 27, is restrained. By aligning the plug body 24 with the inside of the barrel 21, the first knob 28 is rotated to cause the external thread 25 and the internal thread 26 to connect, thus inserting the plug body 24 into the barrel 21. The stop block 27 then contacts the barrel 21, limiting and fixing the plug body 24. When the blow gun body 1 needs to be used, the first fixing block 34 is disassembled by rotating the first knob 28 in the opposite direction. After the plug body 24 is disassembled, the elastic rope 210 retracts the first knob 28, the stop block 27, and the plug body 24 through its self-locking elasticity, bringing them closer to the semi-circular bracket 23 for easy storage.

[0023] Through the above steps, by aligning the plug body 24 with the inside of the barrel 21 and connecting it with the external thread 25 and the internal thread 26, the plug body 24 is inserted into the inside of the barrel 21. This prevents the user from touching the handle switch of the blow gun body 1, which could cause the product to fall or be damaged. This improves the usability of the blow gun body 1 and prevents injury to the user, thus solving the problem that not only is the product easily dropped or damaged, but it can also cause injury to the user.
