[0006] A fan guard includes a front guard, a rear guard, a barrier rod, and a protective net. The rear guard is provided on one side of the front guard. An annular groove for inserting a connecting ring is opened on one side of the front guard. The connecting ring is fixed to the rear guard. Air delivery slots are opened at equal intervals in the middle of the rear guard and the front guard. Spokes are fixedly installed inside each air delivery slot. A groove for installing an adsorption shell is opened in the middle of the outer surface of the front guard and the rear guard. A first adsorption block is fixed on both the front and rear ends of one adsorption shell, and a second adsorption block is fixed on both the front and rear surfaces of the other adsorption shell. Magnetic blocks are provided inside the two first adsorption blocks and the two second adsorption blocks. Barrier rods are fixed at equal intervals on the outside of the two adsorption shells.

[0007] Both the first and second adsorption blocks are magnetically attached to an outer cover. A protective net is fixed in the middle of the outer cover. The protective net has a honeycomb design. The edge of the outer cover is integrally formed with a plug end. A magnetic ring is fixed to the top of the plug end. The magnetic ring is wrapped with a rubber sleeve.

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 7 This utility model provides a technical solution: a fan guard, including a front guard 1, a rear guard 2, a barrier rod 11 and a protective net 13. The rear guard 2 is provided on one side of the front guard 1. An annular groove 4 for inserting a connecting ring 3 is opened on one side of the front guard 1. The connecting ring 3 is fixed to the rear guard 2. Air delivery grooves 5 are opened at equal intervals in the middle of the rear guard 2 and the front guard 1. Spokes 6 are fixedly installed inside each air delivery groove 5. A groove for installing an adsorption shell 7 is opened in the middle of the outer surface of the front guard 1 and the rear guard 2. A first adsorption block 8 is fixed on both the front and rear ends of one adsorption shell 7. A second adsorption block 9 is fixed on both the front and rear surfaces of the other adsorption shell 7. Magnetic blocks 10 are provided inside the two first adsorption blocks 8 and the two second adsorption blocks 9. Barrier rods 11 are fixed at equal intervals on the outside of the two adsorption shells 7.

[0030] External protective covers 12 are magnetically attached to the outside of the first adsorption block 8 and the second adsorption block 9. A protective net 13 is fixed in the middle of the external protective cover 12. The protective net 13 has a honeycomb design. An insert end 14 is integrally formed on the edge of the external protective cover 12. A magnetic ring 15 is fixed on the top of the insert end 14. The magnetic ring 15 is wrapped with a rubber sleeve 16. Considering that there are large gaps between the spokes 6 of the fan cover, some curious children may easily stick their fingers in and get their fingers injured by the fan blades. This utility model effectively prevents children from sticking their fingers into the fan cover and getting injured by the fan blades by using the spokes 6 of the front and rear protective covers 2, the multiple blocking rods 11 on the outside of the adsorption shell 7, and the protective net 13 on the surface of the external protective cover 12. In addition, magnetic adsorption is used between the adsorption shell 7 and the external protective cover 12 for easy cleaning later.

[0031] Each barrier rod 11 has a groove at its end that matches the outer contour of the silicone ring 27. There are two silicone rings 27, which are respectively bonded to the inner walls of the front cover 1 and the rear cover 2. By setting the silicone rings 27, the grooves at the ends of each barrier rod 11 are abutted, thus allowing for secondary fixation using the above structure. This ensures that the adsorption shell 7 will not fall off due to vibration during use. The first fixation is achieved by the magnetic block 10 magnetically adsorbing the front cover 1 or the rear cover 2, and the second fixation is achieved by the end of the barrier rod 11 abutting against the end of the silicone ring 27.

[0032] In this design, the inner walls of the tanks of the front cover 1 and the rear cover 2 are each bonded with a first rubber ring 18 at equal intervals. The first rubber ring 18 abuts against the second rubber ring 19, and multiple second rubber rings 19 are respectively fixedly sleeved on the outside of the side end of the adsorption shell 7. By setting the first rubber ring 18 in conjunction with the second rubber ring 19, the adsorption shell 7 inserted into the tank body plays a role in increasing the friction force, thereby further improving the stability of the adsorption shell 7 after it is inserted into the front cover 1 or the rear cover 2. That is, after the adsorption shell 7 is inserted into the front cover 1 or the rear cover 2, the first rubber ring 18 and the second rubber ring 19 can be used to abut against each other by misalignment.

[0033] Each front cover 1 is fixed with multiple spring pins 20 at equal intervals on its exterior. The pin head of each spring pin 20 passes through the relief groove 21 in the middle of the front cover 1 and the insertion ring 3. The spring pins 20 fix the front cover 1 and the rear cover 2 after they are closed. The pin head of the spring pin 20 passes through the insertion ring 3 and is fixed to the relief groove 21 of the front cover 1.

[0034] The spring pin 20 is fitted with an anti-accidental contact cover 22, and the inner wall of the anti-accidental contact cover 22 abuts against the bracket 23 of the spring pin 20. By setting the anti-accidental contact cover 22 to abut against the outer bracket 23 of the spring pin 20, children are prevented from pulling the spring pin 20. Since the front cover 1 and the rear cover 2 are fixed by the spring pin 20, it is convenient for the user to disassemble the front cover 1 for cleaning.

[0035] The second adsorption block 9 and the magnetic block 10 are both provided with a through hole 24 for the fan head to pass through. The rear cover 2, the second adsorption block 9 and the magnetic block 10 are provided with a through hole for the threaded post 25 to pass through. The threaded post 25 is fixedly installed on the outside of the fan head housing. Each threaded post 25 is provided with a limit nut 26. By providing through holes in the rear cover 2, the magnetic block 10 and the second adsorption block 9, it is convenient for the user to align and install the cover 2 with the threaded post 25 of the fan head.

[0036] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
