Detailed Description
The utility model provides a can dismantle fan blade's fan, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following refers to the drawing and the embodiment of lifting is the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 6, the present invention provides a fan with detachable fan blades.
A fan with detachable fan blades comprises a base 1, a supporting arm 2, a fan head, fan blades 5, a front cover 61 and a rear cover 62, wherein the fan head comprises a rear cover 31, and a motor (not visible in the drawing) arranged in the rear cover, and a chuck 4 (shown in figure 5) is connected to a main shaft of the motor; the fan blade 5 comprises a fan hub 51 and a plurality of blades 52 arranged on the side wall of the fan hub; the fan hub and the chuck are detachably connected; the front cover and the rear cover are detachably coupled (preferably, screwed), and the rear cover 62 is provided on the rear cover 31. Different from the prior art, the chuck is arranged on the main shaft of the motor, and the fan hub is detachably connected with the chuck, so that the fixed connection between the fan hub and the main shaft of the motor is avoided; when the fan blade needs to be cleaned, the whole fan blade can be taken out only by detaching the front cover and separating the fan hub from the chuck, and the fan blade can be quickly reassembled after cleaning.
The fan hub and the detachable connection of the chuck are various, and can be arranged as follows: the chuck is provided with a boss 41, and the boss is provided with a plurality of clamping teeth 42; the fan hub 51 is provided with a concave cavity 510, and the inner wall of the concave cavity is provided with a plurality of barrier strips 53; the latch of the chuck can be inserted into the cavity of the fan hub. That is, the latch of the chuck can be quickly inserted into the cavity of the fan hub to achieve the connection between the two. In addition, because the inner wall of the concave cavity is provided with a plurality of baffle strips, the number of the baffle strips is twice of the number of the clamping teeth. When the latch is inserted into the cavity, two circumferential sides of each latch 42 are limited by the corresponding stop strips 53, so that the fan hub cannot displace circumferentially relative to the chuck during actual operation of the fan. Preferably, the boss is provided with 4 latch teeth, and the cavity is correspondingly provided with 8 stop bars.
Furthermore, a center hole 410 is formed in the boss 41, a core bar 54 is arranged in the middle of the fan hub, and an inverted hook 541 is arranged at the end of the core bar. This arrangement can prevent the fan hub from being displaced axially in actual operation.
Preferably, the motor is a mute brushless motor, and can ensure enough air volume and avoid noise during operation.
Further, the fan head is rotatably connected with the supporting arm, and the fan head can rotate up and down around a horizontal shaft. In actual use, the fan head can be locally adjusted upwards or downwards according to requirements, and the rotation of the fan head is stepless adjustment.
Preferably, the fan head can be rotated 65 ° upwards about the horizontal axis and 15 ° downwards about the horizontal axis.
As shown in the drawings, the fan with the detachable fan blade can be further improved. The base is internally provided with a lithium battery (which cannot be observed in the figure), and the front side of the base is provided with an LED lamp (as indicated by a reference numeral 11), and the LED lamp is electrically connected with the lithium battery. The lithium battery is a rechargeable battery, can be used for supplying power to a motor of the fan, can also be used for supplying power to LEDs and the like, fully utilizes the space of the base and plays a role in illumination.
Further, a USB interface 101 and a micro USB interface 102 are disposed on the base. In practical applications, a charging circuit and a discharging circuit are also arranged in the base, and since the charging and discharging circuit is a prior art, the charging and discharging circuit is not limited in detail here. During practical use, the charging device can be connected with an external power supply through a USB interface to realize charging. And external electronic equipment (such as a mobile phone, a tablet personal computer and the like) is inserted into the corresponding micro USB interface through a data line, and the lithium battery discharges to charge the corresponding electronic equipment. According to actual requirements, a Type-C interface (not shown in the figure) can be arranged on the base to adapt to different electronic equipment.
Through the analysis, in the fan with the detachable fan blades, the fan hub and the main shaft of the motor are not directly connected; but set up the chuck on the main shaft of motor, be connected fan hub and chuck detachably again, consequently, the dismouting of fan leaf does not take place to interfere with the motor main shaft, can conveniently take out the fan leaf in order to wash, can adorn again fast after the washing. Further, an LED lamp may be provided on the base, and a lithium battery may be provided in the base, so that the fan has a lighting function. Furthermore, a charging circuit is arranged in the base, so that the charging circuit can be used for charging common electronic equipment, and the functions of the fan are expanded.
It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
