[0002] Industrial fans are a common industrial machine widely used in large spaces such as industrial plants, logistics warehouses, exhibition halls, and gymnasiums for space ventilation and personnel cooling. They can most efficiently promote large amounts of air movement, generate large air volumes, and form a moving and circulating airflow field in the space, which can effectively regulate the air circulation problem in industrial production workshops.

[0003] In order to reduce the noise of industrial fans at work, noise reduction structures are usually added in today's industrial fans. These noise reduction structures mostly include sound-absorbing cotton and other noise-reducing structures, and the shell is generally fixed to the shell by screws. After long-term work in an industrial environment, the sound-absorbing cotton is easily contaminated with a lot of dirt, and the shell needs to be disassembled to take out the sound-absorbing cotton for cleaning or replacement, which leads to low disassembly efficiency and inconvenient cleaning. Therefore, a noise-reducing industrial fan with high safety, easy installation and cleaning, and strong practicality is proposed. Utility Model Content

[0021] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0022] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0023] One of the preferred embodiments of the present application is as follows: Figures 1 to 5 As shown, a noise reduction industrial fan comprises a shell 1 and an opening and closing piece 2 rotatably arranged on the side of the shell 1; the side of the opening and closing piece 2 and the shell 1 are matched through a locking structure 3, and a placement cavity 11 for placing sound-absorbing cotton is opened inside the shell 1, and the opening and closing piece 2 can fix the sound-absorbing cotton placed in the placement cavity 11; when replacing or installing the sound-absorbing cotton, the locking structure 3 can be used to release the lock of the opening and closing piece 2, and then the opening and closing piece 2 can be rotated to a certain angle along the installation position to open the placement cavity 11, and then the sound-absorbing cotton can be placed in or taken out of the placement cavity 11, so as to facilitate better installation and disassembly, and facilitate better cleaning or replacement, thereby improving the convenience and practicality of the device.

[0024] In this embodiment, Figure 3 and Figure 4As shown, a transverse groove 12 is provided on the side of the shell 1, and the transverse groove 12 is provided for placing the opening and closing piece 2, and the opening and closing piece 2 includes a shell 21 and a pair of connecting rods 22; the pair of connecting rods 22 are installed on both sides of the shell 21, one of the connecting rods 22 is rotatably installed in the transverse groove 12, and the other connecting rod 22 cooperates with the shell 1 through a locking structure 3; when the placement cavity 11 is opened, the lock of the other connecting rod 22 is released by the locking structure 3, and then the shell 21 is driven, so that the shell 21 can be rotated to a certain angle along a connecting rod 22 at the installation position, and then the connecting rod 22 can slide into the transverse groove 12 with the shell 21 for placement, so as to facilitate opening the placement cavity 11 to place or replace the sound-absorbing cotton, facilitate opening and replacement, facilitate cleaning work, and improve the convenience and safety of the device.

[0025] In this embodiment, Figure 2 and Figure 3 As shown, it should be known that a limiting groove 13 is provided on both sides of the transverse groove 12, and a connecting rod 22 is installed in the limiting groove 13, so that the connecting rod 22 can better rotate and slide in the transverse groove 12, and then the opening and closing part 2 can better slide into the transverse groove 12, so as to facilitate the replacement or installation of the sound-absorbing cotton.

[0026] In this embodiment, Figure 1 and Figure 4 As shown, it can be understood that in order to better make the shell 21 be at the same horizontal plane with the shell 1 after installation, thereby improving the aesthetics of the overall device after installation, a closing groove 14 is opened on the side of the shell 1, and the closing groove 14 cooperates with the shell 21, and then extends into the closing groove 14 after the shell 21 is installed and locked, so that the shell 21 is flush with the shell 1, making the overall device beautiful and safe.

[0027] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, it should be known that in order to prevent the shell 21 from slipping out of the transverse groove 12 and falling when the shell 21 is opened and placed, causing adverse effects, a connecting groove that cooperates with another connecting rod 22 is opened on the side of the shell 1, and the connecting rod 22 arranged in the transverse groove 12 is shorter than the other connecting rod 22, so that when the shell 21 is rotated and moved with one connecting rod 22, when the shell 21 extends into the transverse groove 12 to the limit, the longer connecting rod 22 cannot pass through the transverse groove 12, thereby improving the safety of the device.

[0028] It is understandable that in order to better grasp the longer connecting rod 22, a handle is installed on the side of the connecting rod 22, so that the connecting rod 22 can be better operated through the handle.

[0029] It should be known that if Figures 2 to 4As shown, a motor and fan blades are arranged inside the housing 1, and the fan blades are installed at the output end of the motor. The outer shell 21 is arranged on the side of the housing 1, and a slot for air outlet is opened on the outer shell 21.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, it should be known that in order to prevent or reduce the pollution of the sound-absorbing cotton, which leads to a reduction in the noise reduction effect, a dust-proof net is installed at the groove on the outer shell 21 to better prevent external dust from entering the shell 1 and then polluting the sound-absorbing cotton.

[0031] In this embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the locking structure 3 includes a locking rod 31 elastically arranged on the side of the housing 1 by a spring, and a locking groove 32 opened on the side of another connecting rod 22; the locking rod 31 and the locking groove 32 cooperate with each other; when locking is performed, the housing 21 can be driven at this time, and the housing 21 slides from the transverse groove 12 to the extreme position. At this time, the shorter connecting rod 22 at the upper end of the housing 21 slides in the limiting groove 13 to the rotation position of the housing 21, and the connecting rod 22 rotates in the limiting groove 13 to The outer shell 21 is driven to extend into the closed groove 14. When the outer shell 21 is fully extended into the closed groove 14, the longer connecting rod 22 at the lower end of the outer shell 21 extends into the connecting groove opened on the side of the shell 1. At this time, the side of the connecting rod 22 will elastically squeeze the locking rod 31. The locking rod 31 is elastically squeezed, and then the connecting rod 22 can continue to move to the extreme position. At this time, the locking rod 31 just elastically resets to extend into the longer locking groove 32, thereby locking and fixing the outer shell 21.

[0032] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
