Through the technical means adopted by the present invention, the user does not need to use any disassembly tool, that is, the cleaning disc mechanism with the cleaning harness can be easily removed from the driving mechanism for maintenance or repair. It is also very easy and quick to assemble the cleaning disk mechanism back to the drive mechanism, greatly reducing the time required for replacement.

Since the engaging projection of the elastic member is deformed only when pressed in the direction along the shaft body, it is sufficient to bear a certain force in other directions while remaining undeformed. Therefore, when the driving mechanism rotates the cleaning disc mechanism, the engaging convex portion secures the buckle to the buckle recess without being loosened. In an embodiment of the invention, the design of the transmission shaft and the angular cylinder shape strengthens the coupling force between the transmission shaft and the receiving shaft in the rotation direction compared with the cylindrical shape, and there is no connection between the transmission shaft and the transmission shaft. Slippage occurs between the shafts, and the drive shaft slips and idling occurs.

Further, in an embodiment of the present invention, the cleaning harness is positioned by the positioning opening provided on the outer ring surface of the turntable of the cleaning disc mechanism, so that the cleaning harness is not entangled and entangled with each other due to the rotation causing deviation from the original setting position. Keep it in the designed position and maintain a good cleaning effect.

The specific embodiments of the present invention will be further described by the following examples and the accompanying drawings.

Referring to Figures 1 and 2, there are shown perspective views of a first embodiment of the present invention and an exploded view of a first embodiment of the present invention. As shown, the quick release cleaning apparatus 100 according to an embodiment of the present invention includes a drive mechanism 1 and a cleaning disk mechanism 2.

The drive mechanism 1 has an operatively rotatable drive shaft 11, and the cleaning disc mechanism 2 includes a turntable 21, a receiving shaft 22 disposed at the axis of the turntable 21, and a plurality of cleaning harnesses radially connected to the turntable 21. twenty three. The drive shaft 11 can be coupled to the receiving shaft 22. Thereby, the driving mechanism 1 can drive the cleaning disk mechanism 2 to rotate through the transmission shaft 11, and the cleaning wire harness 23 can clean or wipe the ground by the rotary motion.

In this embodiment, the transmission shaft 11 is a shaft and the receiving shaft 22 is a sleeve. Of course, those skilled in the art are aware that the concave-convex fit between such shafts and bushings can be easily replaced with each other. That is to say, the drive shaft can be changed into a bushing, and the receiving shaft is a shaft.

In the shape of the transmission shaft 11 and the receiving shaft 22, the transmission shaft 11 has a angular column shape, and the receiving shaft 22 has a corner-shaped sleeve corresponding to the transmission shaft 11. By the combination of the angular cylindrical design and the shaft and the sleeve of the generally cylindrical design, the coupling force between the transmission shaft 11 and the receiving shaft 22 in the rotational direction is strong, and the receiving shaft 22 and the transmission shaft 11 can be avoided. Slippage occurs so that the drive shaft 11 does not slip turn.

In addition, the outer ring surface of the turntable 21 has a plurality of positioning ports 211 disposed at intervals, and a plurality of cleaning wire harnesses 23 are respectively passed through the respective positioning ports 211. Thereby, the cleaning harness 23 does not deviate from the original setting position when cleaning or wiping the floor, and entangles and knots each other, maintaining a good cleaning effect. Since the conventional turntable is usually provided with a complete one-turn opening, all the cleaning harnesses are passed out from this opening, so when cleaning or wiping the ground, the cleaning harnesses often entangle and tie each other, or gather in the same In the direction, there will be problems with poor cleaning. Of course, the distance between each positioning port 211 can be changed according to different needs, and the size of the positioning port 221 can also be adjusted according to different size cleaning harnesses.

Referring to Figure 3, there is shown a cross-sectional view of the drive shaft and the receiving shaft of the first embodiment of the present invention. The outer surface of the transmission shaft 11 is provided with an elastic member 12 covering the transmission shaft 11. The elastic member 12 is elastically deformed by the force and elastically recovers after the force is released. In this embodiment, it is a metal reed, of course. It can be replaced by a material of the same nature.

The elastic member 12 extends along the shaft of the transmission shaft and is respectively bent at opposite sides of the shaft body of the transmission shaft to form a fastening protrusion 121 (only one is shown), and the fastening protrusion 121 and the transmission shaft 11 are respectively A compression deformation space is formed between the outer surfaces, and the fastening convex portion 121 is an arcuate projection in this embodiment. Such a shape causes the engaging convex portion 121 to be flattened when it is biased from the curved arc surface, and it is not easily deformed if it is biased from other directions. The elastic member 12 is fixed on the transmission shaft 11 by a locking member 13. The locking member 13 is a screw in this embodiment. Of course, it can be replaced by other components or fixed by other means (such as welding). Combine. The receiving shaft 22 is provided with a buckled recess 221 corresponding to the engaging convex portion 121 along the receiving shaft shaft, and the buckled recess 221 has a concave corresponding to the engaging convex portion 121. The body shape is completely covered by the snap protrusions 121 after assembly.

Therefore, when the cleaning disc mechanism 2 is assembled to the driving mechanism 1, the engaging convex portion 121 is subjected to the biasing force of the receiving shaft shaft body and is pressed and deformed (as described above from the curved arc surface), so that the receiving shaft 22 is placed on the drive shaft 11. Until the engagement convex portion 121 reaches the position of the buckled concave portion 221, the fastening convex portion 121 is no longer pressed and elastically restored to its original shape, thereby engaging the buckled concave portion 221 to couple the receiving shaft 22 to the transmission shaft 11.

When the driving mechanism 1 drives the cleaning disk mechanism 2 to rotate by the transmission shaft 11, the fastening convex portion 121 is not easily deformed by the force applied at this time, so that the buckled concave portion 221 is still caught, and the receiving shaft 22 is smoothly passed. Driven by the drive shaft 11.

When the cleaning disc mechanism 2 is detached from the driving mechanism 1, the engaging convex portion 121 is also subjected to the urging force of the receiving shaft body to be deformed under pressure (as described above, from the curved arc surface), so that the receiving shaft 22 can be The drive shaft 11 is disengaged.

Referring to Figure 4, there is shown a cross-sectional view of a drive shaft and a receiving shaft of a second embodiment of the present invention. As shown, the drive shaft 11a is provided with two latching recesses 111 (only one of which is shown) along the shaft of the drive shaft. The outer surface of the receiving shaft 22a is provided with an elastic member 24 covering the receiving shaft 22a. The elastic member 24 is fixed on the receiving shaft 22a by a locking element 13a, and the elastic member 24 extends along the receiving shaft body and is bent to form a corresponding In the engaging convex portion 241 of the buckled concave portion 111, the buckled concave portion 111 has a concave shape corresponding to the engaging convex portion 241, and completely covers the engaging convex portion 241 after assembly.

Similar to the foregoing first embodiment, when the cleaning disc mechanism 2 is assembled to the driving mechanism 1, the engaging convex portion 241 is deformed by the urging force of the shaft portion of the transmission shaft until the engaging convex portion 241 is engaged with the buckled concave portion. 111, the receiving shaft 22a is coupled to the transmission shaft 11a. When the cleaning disc mechanism 2 is detached from the driving mechanism 1, the engaging convex portion 241 is deformed by the urging force of the shaft of the transmission shaft, so that the receiving shaft 22a can be received. The drive shaft 11a is disengaged.

Referring to Figure 5, there is shown a cross-sectional view of a drive shaft and a receiving shaft in accordance with a third embodiment of the present invention. The constituent elements of this embodiment are substantially the same as those of the first embodiment described above, and the same elements are denoted by the same reference numerals. The difference is that the receiving shaft 22b is provided with a buckle member 25 extending along the receiving shaft body and having a buckled recess 251 corresponding to the fastening protrusion 121.

Since the buckled recessed portion 251 is positioned on the buckled member 25 by the provision of the buckled member 25, the structure of the receiving shaft 22b can be simplified, and it is more convenient and easy to manufacture. The buckle member 25 may be made of a material that is not easily deformed for the snap protrusion 121 to be buckled. The buckle member 25 can also use an elastic material so that both the buckle member 25 and the elastic member 12 have elasticity, and the force can be saved during assembly and disassembly.

Similar to the first embodiment described above, when the cleaning disk mechanism 2 is assembled to the driving mechanism 1, the engaging convex portion 121 is deformed by the urging force of the receiving shaft body until the engaging convex portion 121 is engaged with the buckled concave portion. 251, the receiving shaft 22b is coupled to the transmission shaft 11. When the cleaning disk mechanism 2 is detached from the driving mechanism 1, the engaging convex portion 121 is deformed by the urging force of the receiving shaft body, and the receiving shaft 22b is detached from the transmission shaft 11.

Although in the above various embodiments, the engaging convex portion and the engaging concave portion are both two, the actual number is not limited thereto. Further, the shape of the engaging convex portion and the engaging concave portion is also not limited to an arc shape, and other shapes such as a triangle, a trapezoid or the like may be used as long as a similar effect can be achieved.

Further, in the above-described respective embodiments, only the case where the transmission shaft is the shaft and the receiving shaft is the sleeve will be described. However, as mentioned earlier, the concave-convex fit between the shaft and the sleeve can be easily replaced with each other. In practice, it is only necessary to directly replace the shaft and the sleeve of the above embodiment. However, the description of the case where the transmission shaft is a sleeve and the receiving shaft is a shaft is not described in detail, but these changes are included in the scope of the patent defined by the present invention.

It can be seen from the above embodiments that the quick release cleaning device provided by the present invention has industrial utilization value, and therefore the present invention has met the requirements of the patent. The above description is only for the preferred embodiment of the present invention, and those skilled in the art can make other various improvements according to the above description, but these changes still belong to the inventive spirit of the present invention and the following definitions.
