Description

Heat radiation structure of cleaning machine

Technical Field

The invention relates to the technical field of cleaning equipment, in particular to a heat dissipation structure of a cleaning machine.

Background

Along with the development of society, people are increasingly conscious of environmental protection, and the requirements of people on garbage collection are higher and higher. At present, dust collecting equipment is mainly adopted for garbage collection, and the working principle of the dust collecting equipment is that an impeller rotates at a high speed generally, air negative pressure is generated in a sealed shell, and dirt such as dust and garbage is sucked into the dust collecting equipment. Then the dirt is separated from the air in the interior, the dirt is kept at the designated position, and simultaneously the clean air is discharged out of the dust collector. When heavy garbage is treated, such as some glass bottles, the small dust suction equipment is often insufficient in suction force, so that an engine is used as power to enable the dust suction equipment to generate larger suction force.

The problem that the engine has high noise when the dust collection equipment adopts the engine as power is solved, so that the noise generated when the dust collection equipment is used is reduced by arranging a silencer on the engine. The engine can generate larger heat when in work, and the heat dissipation treatment needs to be carried out on the engine and a silencer connected with the engine. The prior art mainly deals with the heat dissipation of the silencer by adding a structure of a heat shield or a heat dissipation plate of the silencer. In the structure, the problem that extra structures and installation spaces are required to be added to the heat dissipation of the silencer is solved, dynamic adjustment cannot be achieved on the heat dissipation of the silencer, and the heat dissipation effect is poor.

Disclosure of Invention

The purpose of the invention can be realized by the following technical scheme: the utility model provides a heat radiation structure of cleaner, includes dust collection bucket and sets up the engine in dust collection bucket below, the engine on be connected with the muffler, be connected with the fan on the output shaft of engine, its characterized in that, dust collection bucket below still is equipped with first casing and second casing, first casing and second casing fixed connection form the installation cavity, the fan setting in the installation cavity, first casing and second casing still form the air-out passageway and with the air outlet of air-out passageway intercommunication, second casing and engine housing connect, the second casing on be provided with the hole of induced drafting, hole and air-out passageway of induced drafting be linked together, the muffler be located the below of air-out passageway and be close to the hole of induced drafting muffler and form the wind channel between the hole of induced drafting.

In this scheme, the cleaner during operation, start the engine, the pivot of engine begins to rotate, the pivot drives the fan rotation, blade on the fan belongs to the antecurvature blade, the flow direction of wind is in the installation cavity again behind the straw of cleaner to the dust collection bucket, enter into the air-out passageway again in the installation cavity, discharge from the air outlet at last, the hole of induced drafting is located the air-out passageway and is facing to the muffler, according to bernoulli's principle, the wind speed on the air-out passageway is very fast, pressure is less, have great heat on engine and the muffler, pressure is great, consequently can form the wind channel between muffler and the hole of induced drafting, the direction of wind flows to the hole of induced drafting from the surface of muffler promptly, discharge from the air outlet through the air-out passageway again.

In the scheme, no additional structure is needed for heat dissipation of the engine and the silencer, and no additional installation space is needed to be added in the cleaning machine; through set up the hole of induced drafting on air-out passageway for heat on engine and the muffler is discharged the outside of cleaner through the mode of absorbing, compares in air-out passageway the wind of going out and directly blows away the heat towards engine and muffler, makes the heat dissipation on engine and the muffler more concentrated, and sets up air-out passageway in the top of muffler, utilizes steam toward the principle that rises, and is better to the radiating effect of engine and muffler. This scheme still has a dynamic adjustment's effect to the heat dissipation of muffler, and when the cleaner needed great suction, engine power was great, can produce more heat on engine and muffler, and the rotational speed of fan was also very fast this moment, and pressure on the air-out passageway is just also less, and the wind-force in wind channel between muffler and the hole of induced drafting is just also big more, just also is better to the radiating effect of muffler.

In the heat dissipation structure of the cleaning machine, the second shell is positioned below the first shell, the air suction hole is connected with the guide pipe, and the guide pipe extends towards the silencer. The stand pipe extends towards the muffler direction for the heat on the muffler is more concentrated is inhaled in the air-out passageway and is discharged outside the cleaner from the air outlet.

In the heat dissipation structure of the cleaning machine, the air outlet channel is in a flaring shape. The air outlet channel is in a flaring shape, so that the flow of the air outlet channel is increased.

In the heat dissipation structure of the cleaning machine, a housing is further arranged below the dust collection barrel, a first ventilation groove is formed in the housing, the first ventilation groove faces the air outlet, the second ventilation groove faces the silencer, and the second ventilation groove is located below the first ventilation groove. The air outlet discharges air out of the cleaning machine through the first ventilation groove on the shell, and cold air is sucked into the shell of the dust collection barrel from the outside of the dust collection barrel through the second ventilation groove, so that the heat dissipation effect on the silencer is improved; the second ventilation groove is arranged below the first ventilation groove, and according to the principle that hot air rises, the hot air discharged from the first ventilation groove is reduced and enters the dust collection barrel through the second ventilation groove, so that the heat dissipation of the silencer is facilitated.

In the heat dissipation structure of the cleaning machine, the number of the second vent grooves is at least one, and the second vent grooves are positioned on the side wall and the bottom of the shell. The number of the second ventilating grooves is multiple, so that the air inlet amount of external cold air is increased, and the heat dissipation of the silencer is facilitated; part second ventilation groove is located the bottom of shell for the cold wind that gets into in the cleaner from the bottom can not receive the steam interference that first ventilation groove came out, is favorable to the heat dissipation to the muffler.

In the heat dissipation structure of the cleaning machine, the second shell is further provided with ribs, and the ribs are connected with the guide pipe. The ribs are used for increasing the strength of the guide tube.

In the heat dissipation structure of the cleaning machine, the silencer is provided with a silencer shell, and the silencer shell is provided with a notch. The surface of the shell of the silencer is provided with the notch, so that air can conveniently enter the surface of the silencer from the notch, and the heat dissipation effect on the silencer is improved.

Compared with the prior art, the invention has the following advantages:

1. this scheme is through setting up the hole of induced drafting on the air-out passageway for heat on engine and the muffler is discharged the outside of cleaner through the mode that absorbs, makes the heat dissipation on engine and the muffler more concentrated, and sets up the air-out passageway in the top of muffler, utilizes steam toward the principle that rises, and is better to the radiating effect of engine and muffler.
