Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, and more specifically, to an axial flow fan that is easy to clean. Background Technology

[0002] An axial flow fan is a device that can circulate a large amount of air.

[0003] Existing axial flow fans are usually used in industrial production and other areas with high concentrations of people or equipment. After long-term use, the fan blades of axial flow fans are prone to accumulating deposits, and the rotation of the fan blades can cause inconvenience when cleaning them.

[0004] Therefore, a new solution is needed to supplement the existing axial flow fan category. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an axial flow fan that is easy to clean.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an easy-to-clean axial flow fan, comprising a fan with fan blades, a shield fixedly mounted on the fan, and a plurality of abutment rods rotatably mounted on the shield, the plurality of abutment rods being able to abut against the fan blades, a sliding plate slidably mounted on the shield, a pulling member for controlling the rotation of the abutment rods being provided between the sliding plate and the abutment rods, a mesh cover detachably connected to the fan, and a switch being provided on the shield that can abut against the sliding plate.

[0007] The present invention is further configured such that: the pulling member is configured as a plurality of first magnets, the first magnets are respectively disposed in the slide plate and at one end of the abutment rod near the blocking member, and the first magnets disposed in the slide plate and the first magnets disposed in the abutment rod correspond one-to-one and attract each other.

[0008] The present invention is further configured such that: a cylinder is fixedly provided on the slide plate, a circular hole is provided on the shield for the cylinder to pass through, and positioning rings are fixedly provided at both ends of the cylinder.

[0009] The present invention is further configured such that when the sliding plate and the blocking member are in contact with each other, the surface formed by the central axis of the several abutting rods is parallel to the bottom surface of the blocking member and the bottom surface of the sliding plate.

[0010] The present invention is further configured such that a second magnet capable of attracting each other is provided on both the side of the shielding member facing the slide plate and the side of the slide plate facing the shielding member.

[0011] The present invention is further provided with a handle on the side of the skateboard away from the obstruction.

[0012] In summary, this utility model has the following beneficial effects: when the user needs to clean the fan blades, by pulling the sliding plate, the abutment rod enters the rotating area of ​​the fan, forming a blockage on the fan blades, thereby facilitating the user to clean the fan blades.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] An easy-to-clean axial flow fan, such as Figures 1-6As shown, the device includes a fan 2 with fan blades 1. A shield 3 is fixedly mounted on the fan 2, and several abutment rods 4 are rotatably mounted on the shield 3. The abutment rods 4 can abut against the fan blades 1. The abutment rods 4 are designed to intrude into the position of the fan blades 1 when the fan 2 is stopped and the fan blades 1 are stationary. Thus, when the user needs to clean the fan blades 1, the abutment rods 4 form a barrier against the fan blades 1, preventing the fan blades 1 from rotating during the user's wiping and cleaning process. After cleaning, the user will... Once the abutment rod 4 is reset to a position where it will not interfere with the fan blade 1, the fan 2 can be powered on and operated. A sliding plate 5 is slidably mounted on the shield 3. A pulling member is provided between the sliding plate 5 and the abutment rod 4 to control the rotation of the abutment rod 4. The pulling member consists of multiple first magnets 8, which are respectively located inside the sliding plate 5 and at one end of the abutment rod 4 near the shield 3. The first magnets 8 on the sliding plate 5 and the first magnets 8 on the abutment rod 4 correspond one-to-one and attract each other. The first magnets 8 are positioned between the sliding plate 5 and the abutment rod 4... The control of the first magnet 8 by the sliding plate 5 is specifically designed so that when the user pulls the sliding plate 5 away from the shield 3, the first magnet 8 attracts the end of the abutment rod 4 towards the shield 3 and moves with the sliding plate 5, thereby causing the abutment rod 4 to rotate in the direction of the fan and eventually enter the area that the fan can pass through when it rotates. A mesh cover 6 is detachably connected to the fan 2. The shield 3 is provided with a switch 7 that can abut against the sliding plate 5. The switch 7 is located in the circuit area and is one of the circuit control structures in the fan 2. The operation and adjustment of the fan 2 are controlled by another circuit control structure when the switch 7 is in the closed state. When the sliding plate 5 is away from the shield 3, the switch 7 is open and the fan 2 does not run. When the sliding plate 5 is in contact with the shield 3, the switch 7 is connected and the fan 2 can run under the control of the user. The setting of this switch 7 is to prevent the fan 2 from running when the abutment rod 4 is inserted into the fan rotation area, so as to minimize the damage between the fan blade 1 and the abutment rod 4.

[0017] A cylinder 9 is fixedly installed on the slide plate 5. A circular hole 13 is opened on the blocking member 3 for the cylinder 9 to pass through. Positioning rings 10 are fixedly installed at both ends of the cylinder 9. The cylinder 9 is used to restrict the movement between the blocking member 3 and the slide plate 5, so that the slide plate 5 can only slide along the cylinder 9. When the slide plate 5 and the blocking member 3 are in contact with each other, the surface formed by the central axis of several abutting rods 4 is parallel to the bottom surface of the blocking member 3 and the bottom surface of the slide plate 5. In this state, the abutting rods 4 are pushed by the slide plate 5 to the state of being away from the rotation area of ​​the fan blade 1, so as to avoid the abutting rods 4 abutting against the fan blade 1.

[0018] Both the side of the shield 3 facing the slide plate 5 and the side of the slide plate 5 facing the shield 3 are provided with second magnets 11 that can attract each other. The second magnets 11 are provided to fix the slide plate 5 and the shield 3 together when they are in contact. When the distance between the slide plate 5 and the shield 3 is separated to the maximum, the attraction force formed by the second magnets 11 on the shield 3 and the second magnets 11 on the slide plate 5 is much smaller than the friction force between the cylinder 9 and the shield 3, the friction force between the slide plate 5 and the cylinder 9, and the sum of the friction forces formed by several first magnets 8. A handle 12 is provided on the side of the slide plate 5 away from the shield 3. The handle 12 is provided to allow the user to separate and pull out the slide plate 5 and the shield 3. At the same time, the attraction of the first magnets 8 forms the insertion of the abutment rod 4 into the rotation area of ​​the fan blade 1.
