Description

Technical Field

[0001] The utility model relates to the technical field of wall-type fans, in particular to a wall-type fan. Background Art

[0002] With the advent of national industrialization, fans have been widely used in industrial production. Fans are machines that rely on input mechanical energy to increase gas pressure and discharge gas. They are a type of driven fluid mechanical fan. They are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and draft of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grains, inflation and propulsion of wind tunnel wind sources and hovercraft, etc. They have the advantages of low noise, large air volume, high efficiency and stable wind pressure. Existing fans can usually only be fixedly installed in the wall or placed on the ground. Their installation method is relatively fixed and has certain requirements on the installation location. They are not very suitable for large amusement parks, farms, open-air venues and other places.

[0003] Patent CN210343791U discloses a low-noise wall-type ventilator, including an outer wall of the fan, a fixing plate welded to one end of the outer wall of the fan, a protective net fixed to the other end of the outer wall of the fan, U-shaped connecting pieces fixed to both sides of the outer wall of the fan, a support frame fixed to one side of the U-shaped connecting piece, bolts fixed to both ends of the support frame, a buckle fixed to the upper end of the support frame, sound insulation cotton fixed to the inner side of the outer wall of the fan, the inner side of the sound insulation cotton fixed to the inner wall of the fan, a fixing frame fixed to the inner side of the inner wall of the fan, and a motor fixed to one side of the fixing frame.

[0004] As can be seen from the attached drawings, the ventilator of the above patent has a protective net directly installed on the other end face of the outer wall of the fan. The protective net protrudes outward relative to the outer wall of the fan, and its aesthetics needs to be improved. There may also be a risk of pricking hands. At the same time, the protective net is fixed to the outer wall of the fan with four screws. When installing the protective net, the protective net is not positioned and needs to be positioned when the first screw is driven in. For this reason, this case was born, and a wall-mounted fan with a protective net that is both beautiful and convenient to install was designed. Utility Model Content

[0023] The utility model embodiment provides a wall-mounted fan, such as Figure 1-4 As shown, it includes a wind tube 1, a fixing frame 2 is horizontally arranged in the wind tube 1, a motor 3 is installed on the fixing frame 2, and a wind wheel 4 is connected to the output end of the motor 3: an end panel 5 is installed on the outer end surface of the wind tube 1, and a surrounding edge 6 is arranged around the end panel 5. A protective net 7 is embedded and installed in the surrounding edge 6 of the end panel 5, and a threaded hole 8 is opened on the end panel 5. Figure 2 As shown, the threaded hole 8 can be realized by welding a nut on the lower end of the end panel 5, and a mounting hole 9 is correspondingly provided on the frame of the protection net 7 for fixing the protection net 7 so that the frame of the insulation net is flush with the surrounding edge 6.

[0024] A further embodiment of the above technical solution is as follows: Figure 4 As shown, a plurality of magnetic blocks 10 are installed on the inner side of the frame of the protection net 7. When the protection net 7 is embedded in the end panel 5, the plurality of magnetic blocks 10 are adsorbed on the end panel 5 to form adhesion. Specifically, the magnetic blocks 10 can be embedded in the frame cavity, and the "small tentacles" extending outward from the frame hold the magnetic blocks 10. The screw-fastened connection and the double connection method of the magnetic blocks 10 can reduce the use of screws, realize the rapid positioning of the protection net 7 on the end panel 5, and achieve faster and more convenient installation.

[0025] In the above technical solution, the end panel 5 and the air duct 1 are integrally formed, and the overall strength is greater. In terms of technology, sheet metal stamping is considered to be used for manufacturing.

[0026] In order to make the outer end surface of the protective net 7 flush with the surrounding edge 6, the installation hole 9 can be set as a countersunk hole. When the screw passes through the countersunk hole to install the protective net 7, the top surface of the screw is flush with the frame of the protective net 7, achieving a more beautiful appearance.

[0027] As for the installation of the wind tube 1, Figure 3 As shown, a sunken frame 11 is arranged around the edge 6 of the end panel 5 , and a fixing hole 12 is opened on the sunken frame 11 . The fixing hole 12 is used for installing the wind tube 1 .

[0028] like Figure 2As shown, a number of reinforcing ribs are arranged at equal angles around the circumference of the wind tube 1 to further improve the strength of the wind tube 1;

[0029] In addition, the wind tube 1, the end panel 5, the protective net 7, the wind wheel 4, etc. can be sprayed with black protective paint to improve the anti-corrosion and anti-rust capabilities of the fan and increase its service life.

[0030] Working principle: For the wall-type fan, the fixing frame 2 in the wind tube 1 can be connected to the inner wall of the wind tube 1 by welding, the motor 3 is fixed to the fixing frame 2, the wind wheel 4 is fixed to the output shaft of the motor 3, and then the wind tube 1 is installed to the outside, and installed through the fixing hole 12 in the sunken frame 11 on the end panel 5, and then when installing the thermal insulation net, the mounting holes 9 on the frame of the protective net 7 are aligned with the threaded holes 8 on the end panel 5, and then the protective net 7 is embedded into the surrounding edge 6 of the end panel 5, and the magnetic block 10 installed on the inner side of the protective net 7 is adsorbed on the end panel 5 to generate adhesion, forming a pre-installation, and then the screws are screwed through the mounting holes 9 to engage with the threaded holes 8 to fix it, thereby completing the installation of the protective net 7, and the thermal insulation net is flush with the surrounding edge 6 of the end panel 5.

[0031] To sum up, the wall-type fan, by setting an end panel 5 on the end face of the wind tube 1, and setting a surrounding edge 6 around the end panel 5, makes the frame of the protective net 7 embedded and installed in the end panel 5, the protective net 7 is flush with the surrounding edge 6 of the end panel 5, the overall aesthetics is better, the abruptness is reduced, and the burrs on the frame of the protective net 7 can also be prevented from pricking the hands; in the wall-type fan, the protective net 7 is embedded in the end panel 5, and the magnetic block 10 on the inner side of the frame of the protective net 7 is quickly adsorbed on the end panel 5, so that the protective net 7 is quickly positioned. In the dual fixing mode of the magnetic block 10 and the screws, the number of screws used can be reduced, which is convenient for the quick installation of the thermal insulation net.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
