Rotatable dust removal tool

Abstract

The rotatable dust removal tool comprises a handle and a cleaning head, a containing cavity is formed in the handle, the cleaning head is rotatably installed at the front end of the containing cavity so as to adjust the angle between the cleaning head and the handle, the cleaning head comprises a first supporting arm and a second supporting arm, and the first supporting arm and the second supporting arm are connected through a connecting rod. The first supporting arm and the second supporting arm can be adjusted in relative position so as to change the width of the cleaning head, and the first supporting arm and the second supporting arm can be mutually opened to detachably support the wiping object and can be mutually contracted to move backwards to enter the containing cavity. According to the dust removal tool, the containing cavity is formed in the handle, the cleaning head can be contained in the containing cavity, the overall containing length and size of the dust removal tool are shortened, and the phenomenon that the sheet-shaped cleaning head is exposed outside and broken is avoided; the cleaning head and the handle are rotationally connected so that the cleaning angle of the dust removal tool can be adjusted to adapt to to-be-cleaned areas at different positions.

Claims

1. A rotatable dust removal tool, comprising a handle and a cleaning head, characterized in that: A storage cavity is provided in the handle, and the cleaning head is rotatably mounted at the front end of the storage cavity to adjust the angle between the cleaning head and the handle. The cleaning head comprises a first supporting arm and a second supporting arm. The relative positions of the first supporting arm and the second supporting arm can be adjusted to change the width of the cleaning head. The first supporting arm and the second supporting arm are open to each other to support a detachable wipe, and close together when moving backward to enter the storage cavity.

2. The rotatable dust removal tool according to claim 1, characterized in that: The first supporting arm and the second supporting arm are staggered with each other, and when the cleaning head moves into the storage chamber, the first supporting arm and the second supporting arm are deformed toward each other by the abutment of the entrance of the storage chamber, and enter the storage chamber in a state of being stacked up and down.

3. The rotatable dust removal tool according to claim 2, characterized in that: A slide groove is provided on the handle, and a sliding assembly is provided between the handle and the cleaning head. The sliding assembly includes a sliding sleeve, a guide rod and a fixed seat. The sliding sleeve is located on the outside of the handle, and the fixed seat is located on the inside of the handle. The first supporting arm and the second supporting arm are both rotatably mounted on the front end of the fixed seat. The guide rod passes through the slide groove to connect the sliding sleeve and the fixed seat, so as to control the sliding sleeve from the outside to drive the cleaning head to enter or leave the storage cavity.

4. The rotatable dust removal tool according to claim 3, characterized in that: The sliding assembly also includes a locking mechanism, which includes a slot and a block. The slot is arranged at the front end of the slot, and the block is movably installed between the sliding sleeve and the sliding sleeve and the fixed seat. A spring is provided between the block and the fixed seat, and the elastic force of the spring causes the block to automatically move upward into the slot when it moves to the slot position, so as to keep the cleaning head in an outwardly extended cleaning state. A button is provided on the block, and the button is located on the sliding sleeve. When the button is pressed, the block moves downward to leave the slot, and the cleaning head can move backward into a storage state.

5. The rotatable dust removal tool according to claim 4, characterized in that: When the cleaning head is in a cleaning state of extending outward, at least a portion of the fixing seat extends out from the front end of the storage cavity, and the cleaning head can be rotated relative to the fixing seat to adjust the cleaning angle.

6. The rotatable dust removal tool according to claim 5, characterized in that: Slide rails extending into the storage cavity are provided on both sides of the slide groove, the length of the slide rails is adapted to the slide groove, and a step is provided at the front end of the slide rails, the position of the step forms the slot, and when the fixed seat moves to the slot position, the block automatically enters the slot for positioning under the action of a spring.

7. The rotatable dust removal tool according to claim 6, characterized in that: The fixing seat is provided with a groove, the slide rail can be inserted into the groove to fix the fixing seat and the handle circumferentially, and the fixing seat moves forward and backward in the storage cavity, and the groove changes its front and rear position relative to the slide rail.

8. The rotatable dust removal tool according to claim 7, characterized in that: The wipe is sleeved on the cleaning head, and a mounting section and a storage section are respectively provided on both sides of the first supporting arm and the second supporting arm. When the first supporting arm and the second supporting arm are opened, the two mounting sections are separated from each other and can cooperate with the wipe to spread the wipe. The mounting section includes a plurality of mounting blocks protruding outward, and the storage section is configured as a straight surface or an arc surface. When the cleaning head enters the storage cavity, the storage section is close to or in contact with the side wall of the storage cavity, and the storage section reduces the resistance with the side wall of the storage cavity.

9. The rotatable dust removal tool according to claim 8, characterized in that: The wipe is arranged in a bag, surrounded on three sides and open on one side, the cleaning head enters the wipe from the opening, the first supporting arm and the second supporting arm are opened and contact the inner surface of the wipe, so that a cleaning surface is formed on the width of the wipe.

10. The rotatable dust removal tool according to claim 9, characterized in that: An inclined surface is provided at the bottom of the mounting block, and the inclined surface cooperates with the receiving cavity to enable the first supporting arm and the second supporting arm to deform and move toward each other when they move backward.
