Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] like figure 1 , figure 2 and image 3 As shown, the adjustable thickness cleaning head brush stick in this embodiment includes a connecting rod 4, a hose 5, a support rod 6, a positioning plate 2, a ratchet 3 and a motor 1, and the connecting rods 4 are arranged in parallel and arranged at intervals. It is ring-shaped; the hose 5 is ring-shaped and has elasticity in the radial direction, there are two and are respectively connected to the two ends of the connecting rod 4 .

[0024] There are multiple support rods 6, which are arranged radially in each hose 5 in a radial shape, and each support rod 6 is also connected to one end of the connecting rod 4; Inside, each positioning plate 2 is provided with a pin shaft that is movably connected to the middle of the support rod 6; connecting cylinders 8 are provided between the positioning...

Abstract

A thickness-adjustable cleaning head brush rod is characterized by comprising a plurality of connecting rods, hoses, supporting rods, positioning discs, ratchet wheels and a motor; the connecting rods are arranged in parallel at intervals to form a ring; the two hoses are annular, have elasticity in the radial direction and are connected to the two ends of the connecting rod respectively; the supporting rods are radially arranged in each hose and are in a radial shape; a pin shaft movably connected with the middle part of each supporting rod is arranged on the positioning disc; the ratchet wheels are rotatably arranged on the corresponding positioning discs, each ratchet wheel is provided with a plurality of ratchets which are arranged in the circumferential direction, tooth grooves with the gradient of the inner wall changing are formed among the ratchets, and the bottom ends of the supporting rods abut against the inner walls of the tooth grooves; and the motor can drive the ratchet wheels to rotate. The motor drives the ratchet wheels to rotate and drives the supporting rods to swing around the pin shaft, the supporting rods further drive the hoses to retract inwards or extend outwards, and therefore thickness adjustment of the brush rod is achieved.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a brush rod applied to a cleaning head. Background technique [0002] Brush bars are used in vacuum cleaners as part of the cleaning head to agitate the dirt on the surface to be cleaned. The agitation helps the dust to rise from the table so that it can then be sucked into the separator. At present, the size of the brush rod in the current suction head is fixed, so the gap between the brush rod and the housing is also fixed, so the suction head can only suck the dust smaller than the gap, and cannot do anything for larger particles of dust. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cleaning head brush rod with adjustable thickness in view of the above-mentioned technical status quo. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning head brush ...
