The utility model discloses a core innovation point lies in:
(1) to the big or small rubbish of different specific gravities, divide the inner chamber of dustbin into the compartment of left, middle, three different appearance chamber size in the right side, wherein, to the less rubbish of specific gravity, for example: leaves, dust and the like are sucked into a left compartment and a right compartment with larger volume of the containing cavity by utilizing a front pure suction type suction nozzle mechanism; for waste with a low specific gravity, for example: scrap iron, soil and stone particles and the like are sucked into a middle compartment with a small volume of the containing cavity by a rear blowing-sucking suction nozzle mechanism with the help of the blowing-assisting power of a fan;
because the volume of the containing cavities of the left compartment and the right compartment is larger, the air flow rate in the compartments is smaller, and the garbage with small specific gravity is convenient to settle; although the volume of the cavity in the middle compartment is smaller, the air flow rate in the compartment is higher, the baffle is separated from the left and right compartments, so that the disturbance of the air flow to the garbage with small contrast can be effectively avoided, and secondly, the partition net is arranged on the upper parts of the left and right compartments and the middle compartment to block, so that the flaky light-bubble garbage in the left and right compartments can be effectively prevented from entering the middle compartment along with the air flow, and further the air outlet partition net of the garbage can is blocked, and a large amount of dust is prevented from entering the fan along with the air flow to damage the fan;
(2) the classified suction of the garbage with different specific gravity is completed by utilizing the suction and pickup pressure difference generated by the front suction nozzle mechanism and the rear suction nozzle mechanism (namely, the pure suction nozzle mechanism and the blow-suction nozzle mechanism); the light garbage with small specific gravity is sucked and picked up by utilizing the small sucking and picking pressure generated by the front suction nozzle mechanism; the heavy garbage with large specific gravity is sucked and picked up by utilizing larger sucking and picking pressure generated by a rear blowing and sucking suction nozzle mechanism;
the suction and pick-up pressure difference generated by the front suction nozzle mechanism and the rear suction nozzle mechanism (namely the pure suction type suction nozzle mechanism and the blowing and sucking type suction nozzle mechanism) is formed according to the following specific principle:
because the front suction nozzle mechanism (namely, the pure suction nozzle mechanism) is only communicated with the external atmosphere, when the fan sucks the air in the dustbin, the air pressure in the dustbin is lower than the external atmosphere pressure, and the generated internal and external pressure difference is the suction and pickup pressure of the front suction nozzle mechanism (namely, the pure suction nozzle mechanism);
because the rear suction nozzle mechanism (i.e. the blowing-sucking suction nozzle mechanism) is not only communicated with the external atmosphere, but also communicated with the outlet of the fan, when the fan sucks the air in the dustbin, and the air pressure in the dustbin is lower than the external atmospheric pressure, part of high-pressure air flow blown out by the fan can be blown into the blowing-assisting cavity of the rear suction nozzle mechanism (i.e. the blowing-sucking suction nozzle mechanism), so that the air pressure in the blowing-assisting cavity of the rear suction nozzle mechanism (i.e. the blowing-sucking suction nozzle mechanism) is far higher than the external atmospheric pressure, and the internal and external pressure difference formed between the blowing-assisting cavity and the dustbin is the suction pressure of the rear suction nozzle mechanism (i.e. the blowing-sucking suction nozzle mechanism);
therefore, the suction and pickup pressure of the rear suction nozzle mechanism (namely the blowing-sucking suction nozzle mechanism) is far greater than that of the front suction nozzle mechanism (namely the pure sucking suction nozzle mechanism) due to the function of the blowing-assisting cavity;
the principle is the suction and pickup pressure difference formation principle of the front and the rear suction nozzle mechanisms (namely the pure suction type suction nozzle mechanism and the blowing and sucking type suction nozzle mechanism).
(3) According to the requirements of application occasions, the suction and pickup pressure difference between the front suction nozzle mechanism and the rear suction nozzle mechanism can be changed by adjusting the caliber of the circulating air port of the air guide cover;
the suction-pickup differential pressure regulation principle between the front suction nozzle mechanism and the rear suction nozzle mechanism is as follows:
when the rotating speed of the fan is unchanged, if the opening degree of the circulating air opening of the air guide cover is increased, the high-pressure air flow blown into the blowing-assisting cavity of the blowing-sucking suction nozzle mechanism is increased, and the suction pressure of the blowing-sucking suction nozzle mechanism is increased; meanwhile, as the airflow entering the dustbin from the blowing-sucking type suction nozzle mechanism is increased, the internal and external pressure difference of the dustbin is reduced, and the suction pressure of the pure-sucking type suction nozzle is reduced.
On the contrary, if the opening of the circulating air opening of the air guide cover is reduced, the suction pressure of the blowing-suction type suction nozzle is reduced, and the suction pressure of the pure suction type suction nozzle is increased.
By analogy, when the rotating speed of the fan and the opening degree of the circulating air opening of the air guide cover are changed simultaneously, the variation ranges of the suction pressure and the suction pressure difference of the two suction nozzle mechanisms are wider.
(4) For the higher specific gravity, the blowing-sucking type suction nozzle mechanism is adopted to suck the garbage into the middle compartment with the smaller volume of the containing cavity by means of the circulating blowing-assisting power of the fan, so that the power for sucking the garbage by only depending on the blowing-sucking type suction nozzle mechanism is reduced, and the energy consumption required by the sweeper is greatly reduced.
Compared with the prior art, the utility model discloses an advantage and beneficial effect are:
(1) the novel differential pressure type garbage classification suction and pickup technology is adopted to suck and pick up the garbage with different specific weights, so that the structure is greatly simplified, and the operation power consumption and the oil consumption are reduced;
(2) the suction and pickup pressure difference of the front suction nozzle mechanism and the rear suction nozzle mechanism can be adjusted to achieve the best suction and pickup effect and meet different working requirements
(3) The garbage can is divided into separate bins which are respectively communicated with different garbage suction and pickup mechanisms, so that the sedimentation of the light foam garbage is facilitated
(4) The abrasion of the fan is reduced, and the service life of the fan is prolonged;
(5) the cleaning efficiency and the cleaning cleanliness are greatly improved, and secondary dust emission is reduced.
