the long strip-shaped dust-absorbing cleaning head is hereinafter referred to as a suction cleaning head, and the suction cleaning head is transversely arranged at the front end of the pushing frame; the structure of the suction and sweeping head is that the suction and sweeping head consists of a long strip slit shell, a plurality of direct current ducted booster fans and a brush roller; the slit shell is characterized in that a slit with the width of 1-2cm communicated with the ground is arranged in a strip-shaped shell, the slit is formed by a shell rear wall and a partition plate which is upwards extended from a shell bottom plate, a certain distance is reserved between the upper edge of the partition plate and the top of the shell, the distance is the same as the width of the slit, the partition plate and the front wall of the shell form a static pressure settling bin, an air draft hole is formed in the top surface of the shell at intervals of 20-25cm, the air draft hole is deviated from the corresponding position of the slit, a direct current ducted booster fan is installed on the air draft hole, and negative pressure is generated at the bottom of the suction sweeping head through the backward suction force of the fan; each direct current duct booster fan is connected with an upper air pipe, the air outlet end of each air pipe is inserted into the dust collection barrel, and the outlet of each air pipe is close to the dust filtration water liquid level; the brush roller is arranged in parallel with the shell, two ends of the brush roller are connected with the shell through a connecting plate, the brush roller is structured in such a way that a plurality of rows of bristles are arranged in the length direction of the shaft roller, and the number of rows of bristles is preferably that at least one row of bristles contacts the ground when the brush roller rotates; the shaft end of the brush roller is connected with a 12V brush driving motor, the brush driving motor drives the brush roller to rotate, the rotating direction is opposite to the walking theory, and the rotating linear speed is higher than the forward normal walking speed of the whole machine.
Furthermore, in order to clean the dust particles in the dust chamber, a cleaning door or a drawer box is arranged in front of the shell; when the drawer box is arranged, the rear wall of the drawer box is tightly attached to the partition plate; it should also ensure the tightness of the cleaning door or drawer box against air leakage.
The power supply and the control box are arranged at proper positions of the chassis; the power supply is a storage battery; a power supply control panel and a motor control panel are arranged in the control box; the power supply control board is provided with a voltage transformation and stabilization circuit, a battery protection circuit and the like; the motor control board is provided with a dust collection fan and a stepless speed regulation circuit and a control circuit of a brush roller driving motor, and is used for controlling the starting, the stopping and the stepless speed regulation of the motor, and a starting, stopping and stepless speed regulation switch is arranged on a hand-held handlebar; the above-mentioned stepless speed-regulating switch is a rotating-handle type speed-regulating switch like an electric bicycle.
Furthermore, in order to ensure the suction force of the suction and sweeping head and the ejection force of the bristles, the bristles are bristles with certain elasticity, and the height between the bottom surface of the suction and sweeping head and the ground is not more than the width of the slit.
Furthermore, in order to prevent larger particle impurities from being sucked into the fan to damage fan blades of the fan, a filter screen is arranged below the hole, and the meshes of the filter screen are smaller than 1/4-1/5 of the gaps of the fan blades.
The working principle is that when the power supply is turned on and the dust collector is pushed to move forward, the mixed dust particles on the ground of a workshop are sucked into the slit at a high speed under the action of the suction force of the suction head, after the dust particles come out of the slit, fine dust is sprayed into filter water of the dust collecting barrel along with high-pressure air flow to be humidified, heavier particles can be thrown out of the high-pressure air flow to be settled and enter the static-pressure settling bin, and larger particles are blocked by the filter screen. When some heavy sundries are not sucked completely, particularly ground-adhering fragments and particles which are not easy to suck are stirred forwards by the brush roller to generate the motive force of being separated from the ground, the heavy sundries are easily sucked away, and the heavy sundries which are not sucked are continuously swept forwards by the brush roller to be concentrated at the corners of a workshop.
The advantages are that: because the fans of the suction and sweeping head are uniformly distributed in the length direction, the suction force is large, the suction force is uniform in the whole suction and sweeping width, the large and small debris and dust particles are swept at one time, the dust and the particles are separated, the small dust enters the filtered water of the dust collection barrel and does not fly upwards when being poured out, and the large particles cannot enter the fans to prevent the fan blades from being damaged; because the suction cleaning head is in a long strip shape, the length of the suction cleaning head can be designed according to the specific space condition of a workshop, the length can reach several meters, the cleaning width is large once, the whole workshop can be cleaned once after several times of cleaning, the suction cleaning head belongs to a semi-automatic tool, and the use is convenient.
The direct-current ducted fan adopted by the invention is also called a brushless ducted fan, is generally used for a small unmanned aerial vehicle, can generate larger lift force compared with an isolated fan with the same diameter, and the fan is annularly enclosed in a duct, so that the pneumatic sound of the fan can be prevented from being spread outwards, the structure is compact, the safety is high, the suction and sweeping head is light and convenient, the suction force is large, generally, metal small blocks with the weight of more than ten grams can be sucked, and the noise is low.
