The invention relates to methods and devices for collecting dust - vacuum cleaners for cleaning, electronic devices, industrial equipment.

A known way of cleaning off dust with a vacuum cleaner which is part of the cleaned object creates a suction directed flow of air, breathtaking dust particles, which is then directed through the hose to the filter of the vacuum cleaner and discharged purified remote from the cleaned object. This method is implemented by a device in the form of cleaner containing an inlet and outlet located in the housing of the dust collector, air filter, air suction unit, suction hose (see the patent of Russia №2019121, A 47 L 5/14 from 15.09.84).

The disadvantage of this method and device is the inability to clean hard to reach places, especially in electronic equipment, industrial equipment, crevices, recesses, etc.

A known way of cleaning off dust with a vacuum cleaner which is part of the cleaned object by moving the brush within the area of the suction effect on the dust attached to the surface of an object, mix this with air, creating a suction directed flow of air, breathtaking dust particles, which is then directed through the hose to the filter of the vacuum cleaner and discharged purified remote from the cleaned object. This method implements the I device in the form of a vacuum cleaner, contains the input and output nozzle located in the housing of the dust collector, air filter, air suction unit, suction hose connected to the inlet side, a brush connected with the suction hose (see the patent of Russia №2181252, A 47 L 5/14, B. I. No. 11, 11.2002,).

This method and the design of the cleaner have the advantage over the above analogy, because the brush effect on the dusty, hard-to-reach places and promotes evacuation of dust in the zone of capture its flow of intake air.

Lack of fashion and design is the inability to clean hard to reach, geometrically-complex parts products especially electronic equipment, industrial equipment, crevices, recesses, etc. where brush or can't get in dusty places, or may cause damage to the parts (components), the exact mechanisms (various instruments, watch movements). It should be noted that often the dust can be electrified (in electronic devices, for example) and because of this very firmly attached to the dielectric material. From the point of view of aerodynamics, in the border with solid surfaces areas and the speed of the suction flow is low. Therefore, to tear such particles suction flow is very difficult, because the flow velocity decreases in proportion to the square of the distance from the edge of the suction hole is (nozzle), and closer to the edge of the suction holes not possible due to the complex profile of the surface being cleaned.

A known method of cleaning dust with a vacuum cleaner, in which a part of the cleaned object in the zone of the suction effect of the pulses directed flows of compressed air, a compressed air blow off dust particles from the surface, mixing them with air to create suction directional airflow that captures and directs the dust particles to the filter of the vacuum cleaner (see A.S. USSR №1664423).

However, the range of the purified products by this method is limited, because in this way does not change the characteristics of the compressed air pulses: frequency, duty cycle, amplitude of the flow velocity and pressure of the compressed air from the condition of maximum activation dust without damaging the elements of the surface being cleaned, and the pause is not evacuated activated dust airborne dust particles.

A known way of cleaning off dust with a vacuum cleaner, according to which part of the cleaned object in the zone of the suction effect on attached to the surface of the dust pulses directed flows of compressed air, a compressed air blow off dust particles from the surface, mixing them with air to create a suction directed flow of air, breathtaking dust particles, and send it to the filter of the vacuum cleaner, and in% the SSE processing will change the characteristics of the pulses of compressed air, the orientation and shape of the jets, while changing the frequency of the pulses of compressed air, the duty cycle, the amplitude of the flow rate and pressure of the compressed air from the condition of maximum activation of the dust without damaging the elements of the surface being cleaned, and in the pause between pulses carry a complete evacuation of activated suspended dust particles (see published application RU # 2002119198/12 from 05.01.04). The disadvantage of this method is that the momentum directed flow of compressed air and suction air flow is continuous. This leads to weak activation of dust and to the deviation of the flow directed flow of compressed air, the loss of energy of the pulse, increases the activation time of dust, which reduces the speed and quality of cleaning dusty surfaces of the parts.

The objective of the invention is improving the quality and speed of cleaning complex profile products.

This objective is achieved in that in the method of cleaning dust from a vacuum cleaner, according to which part of the cleaned object in the zone of the suction effect on attached to the surface of the dust pulses directed flows of compressed air, a compressed air blow off dust particles from the surface, mixing them with air to create a suction directed flow of air, breathtaking dust particles, and send it to the filter of the vacuum cleaner, and in the process of processing the TCI will change the characteristics of the pulses of compressed air, the orientation and shape of the jets, while changing the frequency of the pulses of compressed air, the duty cycle, the amplitude of the flow rate and pressure of the compressed air from the condition of maximum activation of the dust without damaging the elements of the surface being cleaned, the flow pulse flow of compressed air, carry packs, and in the cleaning process change: the number in packs, shape, duty cycle, shape, frequency, and duty cycle of repetition of the pulse packet, from the condition of maximum speed activation dust, and the evacuation of the carry pulses directed suction air flows, and in the cleaning process change the orientation, the shape of the suction air flows, the form, frequency, duty cycle pulses, the amplitude of the flow rate and pressure of suction air to the suction air flow from the condition of maximum speed the evacuation of the dust without damaging the elements of the surface being cleaned, in addition:

- change the characteristics of the pulses directed and suction air flow is produced on the basis of the analysis of the dust concentration in the air when it is activated and evacuation;

- applying pulses of suction air flows is carried out in the intervals between the packets of pulses flow of compressed air;

in the activation process and the evacuation of the dust and changing the distance between the nozzles of the flow of compressed air, suction sweat the ka air and surface which is cleaned from dust, from the condition of maximum speed activation and evacuation of dust.

The essence of the method of cleaning dust from a vacuum cleaner is to use a controlled pulses of compressed air for removing dust particles from solid surfaces in hard to reach places that remove then directed pulses of suction flow air cleaner.

In parts of the cleaned object in the zone of the suction effect on attached to the surface of the dust pulses directed flows of compressed air, a compressed air blow off dust particles from the surface, mixing them with air. The pulse flows of compressed air serves packets in the activation phase dust. In the cleaning process change the number in packs (1...100, for example), shape, duty cycle, pulse frequency and form, the duty cycle of repetition of the pulse packet, from the condition of maximum speed activation dust on the surface. The advantage of filing a series of short pulses in the phase of activation dust before applying one long pulse is to create a pulsating flow of compressed air with variations in pressure, allowing you to more quickly tear off the attached dust particles through the creation of pulsating turbulent flow of air near the surface. New is also the change in the shape of a single pulse and forms bundle is mulsow. May be sinusoidal shape - soft effect on the dust and parts (for damageable parts). Rectangular shape with a steep front and rear fronts creates a powerful vibration in the air due to the sudden pressure drop between pulses allows to reduce the time and improve the quality of activation dust. The steepness of the front and back edge of the pulse of change, this allows you to change the speed of the rise and fall of air pressure in the air flow, pulsation and turbulence of the compressed air stream and differently affect the dust and parts that are cleaned. Dust is activated and is in a suspended state.

Create a suction directed flow of air, which produces the activated capture dust particles (suspended in air), and evacuate him to the filter of the vacuum cleaner, the suction of the dust-Laden air is realized by the pulses directed suction air flow that is new. In the particular case of pulses directed suction air flow can be out of phase (pauses) between phases activation dust (single pulse or packet of pulses). But the temporal length of the pulse may be greater than the length of the pause between pulses or packets of pulses directed flows of compressed air activation phase, which leads to the curvature of the trajectory directed the x flow of compressed air in the activation phase dust at some point in time, that speeds up the activation process dust (pulse suction flow time overlaps with the temporal space of the pulse stream of compressed air). In the cleaning process change the orientation and shape of the suction air flows, the form, frequency, duty cycle, amplitude of the flow velocity and pressure of suction air to the suction air flow from the condition of maximum speed the evacuation of the dust without damaging the elements of the surface.

In the activation process and the evacuation of the dust and changing the distance between the nozzles of the flow of compressed air, the intake air flow and the surface, which is cleaned from dust, from the condition of maximum speed activation and evacuation of dust. The closer to the surface with dust nozzle flows of compressed air and discharged air, the higher the air speed is there when you activate dust and evacuation of airborne dust, than on the contrary. This allows you to create a ripple in the amplitude of the flow velocity and pressure, bringing and removing the nozzle to dust the surface, it further accelerates the activation process and the evacuation of dust. This is ensured by the movement mechanisms of these nozzles.

The change of the characteristics of the pulses directed and suction air flow is produced on the basis of the analysis of the dust concentration in the air when activated and evacuation. Uh what about the possible if the dust concentration is evaluated using sensors dust in the air. The received data is analyzed by the control unit and accounted for the formation of pulses of the air flow for activation and evacuation of dust from the ground up to ensure maximum speed and quality of cleaning, evacuation of dust. The device of the vacuum cleaner, a control unit, sensors may be different and the modern development of technology can be implemented in different ways, can be used microprocessors, impulse control valves, pneumobilia, vakuutusyhtio etc..
