[0029] The advantages and features of the present invention and methods for achieving them will become apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in a variety of different forms. These embodiments are provided merely to complete the disclosure of the present invention and enable those skilled in the art to fully understand the scope of the present invention. The present invention is limited only by the scope of the claims. The same reference numerals represent the same components throughout the specification.

[0030] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0031] like Figures 2 to 6 As shown, the handheld cleaning device of an embodiment of the present invention is used to clean the workbench 100 of the panel production equipment. A plurality of support rods 200 for supporting the panel are arranged at intervals on the workbench 100. The support rods 200 extend in the vertical direction (the vertical direction is the Z direction in the figure). The handheld cleaning device includes a base 1, a handle 2 and a cleaning head 3. The handle 2 is arranged on the base 1, and the cleaning head 3 is rotatably arranged at the bottom of the base 1. The rotation axis of the cleaning head 3 extends in the vertical direction. The size of the cleaning head 3 in the vertical direction is larger than the size of the support rod 200.

[0032] It can be understood that by rotatably arranging the cleaning head 3 and the base 1, and the size of the cleaning head 3 in the vertical direction is larger than the size of the support rod 200, the operator can avoid the base 1 and the support rod 200 from colliding during the movement of the workbench 100 by pushing the base 1 through the handle 2, and when the cleaning head 3 abuts the support rod 200, as the operator continues to push the cleaning head 3, it can rotate around the support rod 200 under the pressing force of the support rod 200, reducing the hard collision between the cleaning head 3 and the support rod 200, ensuring the safety of the handheld cleaning device and the structural stability of the support rod 200, thereby ensuring the stability of the support rod 200 supporting the panel, and the cleaning head 3 can rotate around the support rod 200 to clean the support rod 200, thereby improving the cleanliness of the support rod 200.

[0033] Furthermore, if Figure 5 and Figure 6 As shown, the base 1 is provided with a liquid storage chamber 11 for containing cleaning liquid, and the cleaning head 3 is provided with a linkage chamber 31. The liquid storage chamber 11 and the linkage chamber 31 are connected. A plurality of liquid outlets 32 are provided at intervals on the outer periphery and bottom of the cleaning head 3. The cleaning liquid in the liquid storage chamber 11 is used to replenish the cleaning head 3, preventing the cleaning head 3 from drying out and making it difficult to remove impurities, thereby ensuring the cleaning effect of the cleaning head 3. Of course, the liquid outlets 32 can be provided only on the outer periphery or the bottom of the cleaning head 3.

[0034] Furthermore, the length of the liquid storage chamber 11 extends along a first direction and passes through a side surface of the base 1 to form a first communication port 12 (the first direction is the X direction shown in the figure, i.e., the horizontal direction). One end of the handle 2 is slidably arranged in the liquid storage chamber 11, and the other end of the handle 2 extends to the outside of the first communication port 12. The first direction is arranged perpendicular to the vertical direction. By setting the handle 2 and the liquid storage chamber 11 to be slidably connected, the length of the handle 2 inserted into the liquid storage chamber 11 can be adjusted to achieve the adjustment of the length of the entire handheld cleaning device, thereby improving the adaptability of the handheld cleaning device. Of course, the space in the liquid storage chamber 11 can also be squeezed by pushing the handle 2, so that the cleaning liquid in the liquid storage chamber 11 can flow to the cleaning head 3, thereby ensuring the liquid discharge effect of the cleaning liquid.

[0035] It should be noted that the first connecting port 12 is arranged at one end of the base 1 along the first direction, and the cleaning head 3 is adjacent to the other end of the base 1 along the first direction, so as to ensure that when the handle 2 is inserted toward the cleaning head 3, the linkage cavity 31 in the cleaning head 3 is always connected with the liquid storage cavity 11.

[0036] Optionally, the handheld cleaning device further includes a sealing ring 4. The sealing ring 4 is provided at one end of the handle 2 located within the liquid storage chamber 11, and the sealing ring 4 abuts against the wall of the liquid storage chamber 11. The provision of the sealing ring 4 can strengthen the sealing between the handle 2 and the wall of the liquid storage chamber 11, thereby preventing the cleaning liquid from flowing out from between the handle 2 and the wall of the liquid storage chamber 11.

[0037] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 As shown, the wall of the liquid storage chamber 11 and the handle 2 are both cylindrical. A snap-fitting portion 13 protrudes from the wall of the liquid storage chamber 11, adjacent to the first communication port 12. A guide groove 21 is recessed into the outer peripheral wall of the handle 2, extending in a first direction. The snap-fitting portion 13 slidably engages with the guide groove 21. The coordination of the snap-fitting portion 13 and the guide groove 21 enhances the stability of the connection between the handle 2 and the base 1 and the guidance of the handle 2 during movement. Of course, the liquid storage chamber 11 and the handle 2 can also be configured as equivalent quadrilaterals, pentagons, or other polygonal shapes.

[0038] Furthermore, a plurality of engaging grooves 22 are provided on a groove wall arranged along the second direction of the guide groove 21, all of which are arranged at intervals along the first direction, and the engaging grooves 22 extend along the circumference of the handle 2. The engaging portion 13 can be engaged with the engaging groove 22, and the second direction is perpendicular to the first direction. The handle 2 is rotated forward to engage the engaging portion 13 with the engaging groove 22. At this time, the engaging portion 13 is blocked by two groove walls arranged along the first direction on both sides of the engaging groove 22, so that the base 1 and the cleaning head 3 can be pushed by pushing the handle 2; the handle 2 is rotated backward to slide the engaging portion 13 out of the engaging groove 22 and into the guide groove 21. At this time, the handle 2 can be pulled or pushed to move relative to the base 1. After adjusting the length of the handle 2 extending relative to the base 1, the handle 2 is rotated forward to engage the engaging portion 13 with the engaging groove 22, and the workbench 100 can be cleaned by the handheld cleaning device again. The handle 2 is highly adjustable.

[0039] It is worth noting that in the example of this embodiment, the second direction is the same as the vertical direction. Of course, as the angle of rotation of the handle 2 changes, the second direction can also be perpendicular to the vertical direction and the first direction.

[0040] Optionally, the handheld cleaning device further includes a traction rope, one end of which is fixed to the base 1, and the other end of which is connected to the end of the handle 2 located outside the liquid storage chamber 11. When the handle 2 is telescopically adjusted, the base 1 and the cleaning liquid contained therein are relatively heavy, so when the handle 2 is pushed out to lengthen the overall length of the handheld cleaning device, it can be directly dragged, which will not cause a large amount of movement of the base 1. However, when the handle 2 needs to be inserted into the liquid storage chamber 11 to shorten the overall length of the handheld cleaning device, there is a certain pressure in the liquid storage chamber 11. If the handle 2 is directly pushed, it is easy to push the base 1 to move. Therefore, the setting of the traction rope enables the operator to pull the traction rope with one hand and push the handle 2 with the other hand, so that the position of the base 1 connected to the traction rope is relatively fixed. At this time, pushing the handle 2 can further insert it into the liquid storage chamber 11, thereby improving the convenience of adjusting the handle 2.

[0041] In addition, a reel structure can be provided at the end of the handle 2 away from the base 1, so that the traction rope is connected to the reel structure, so that no matter how long the handle 2 is extended, the traction rope can still remain taut at both ends. The reel structure is relatively existing and is not the focus of this solution, so a specific structural example is not provided. Of course, a dust removal port can also be provided at the bottom of the base 1 and adjacent to the side of the base 1 away from the handle 2. The dust removal port is connected to an external negative pressure device to enable the handheld cleaning device to first remove dust and then apply cleaning when it is pushed on the workbench 100, thereby improving the usability of the handheld cleaning device.

[0042] In some embodiments, as Figure 5 and Figure 6As shown, a connecting portion 15 is protruding from the bottom of the base 1, and the cleaning head 3 is rotatably connected to the connecting portion 15. For example, a linkage cavity 31 vertically passes through the top of the cleaning head 3, and the connecting portion 15 is inserted into the linkage cavity 31, and the outer peripheral wall of the connecting portion 15 is rotatably connected to the inner side wall of the linkage cavity 31. Of course, a bearing 8 can be provided between the outer peripheral wall of the connecting portion 15 and the inner side wall of the linkage cavity 31 to improve the rotation convenience of the cleaning head 3.

[0043] Furthermore, the handheld cleaning device also includes an elastic plug 5. A second connecting port 14 is provided at the bottom of the base 1. The second connecting port 14 connects the liquid storage chamber 11 and the linkage chamber 31. The elastic plug 5 is provided at the second connecting port 14, and a liquid outlet groove 51 is provided vertically through the elastic plug 5. To prevent the cleaning liquid in the liquid storage chamber 11 from actively flowing into the linkage chamber 31 for release, the second connecting port 14 is blocked by the elastic plug 5. In its natural state, the elastic plug 5 has a certain elasticity. The cavity wall of the second connecting port 14 squeezes the elastic plug 5 to compress and close the liquid outlet groove 51, thereby reducing the connection between the liquid storage chamber 11 and the linkage chamber 31. When it is necessary to add cleaning liquid to the cleaning head 3, the handle 2 is pushed to squeeze the cleaning liquid in the liquid storage chamber 11, so that the cleaning liquid can open the liquid outlet groove 51 and flow into the linkage chamber 31. The provision of the elastic plug 5 can effectively improve the storage stability of the cleaning liquid in the liquid storage chamber 11.

[0044] The handheld cleaning device also includes a cover 6. The top of the base 1 is provided with a liquid filling port communicating with the liquid storage chamber 11. The cover 6 is used to seal the liquid filling port. The provision of the liquid filling port facilitates the addition of cleaning fluid to the liquid storage chamber 11. It is understood that the cover 6 is detachably connected to the base 1 to enable the liquid filling port to be opened or closed. For example, the inner sidewall of the liquid filling port is provided with an internal thread, and the outer peripheral wall of the cover 6 is provided with an external thread. The internal and external threads cooperate, and the threaded connection facilitates assembly and disassembly.

[0045] In other embodiments, the cleaning head 3 includes a connector 33 and a cleaning cloth 34. The connector 33 is rotatably connected to the base 1, and the cleaning cloth 34 is detachably connected to the outer side of the connector 33. By detachably connecting the cleaning cloth 34 to the connector 33, it is convenient to replace and clean the cleaning cloth 34. For example, a circle of mounting grooves 35 are formed on the outer wall of the cleaning head 3. The cleaning cloth 34 wraps around the bottom of the cleaning head 3 while the circumference of the cleaning cloth 34 is sleeved on the outer periphery of the cleaning head 3. The cleaning cloth 34 is bound by a strap 7, and the strap 7 is clamped in the mounting groove 35, thereby improving the convenience and stability of the connection between the cleaning cloth 34 and the connector 33.

[0046] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be manufactured in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or basic features of the present invention. Therefore, it should be understood that the above embodiments are illustrative and not restrictive in all aspects.
