Particularly, the existing dust collector is improved according to the invention, so that indoor ventilation can be realized at low cost, indoor cleanness can be kept, and the prevention and treatment effect of new crown epidemic situation can be improved.
Description
Technical Field
The invention relates to a dust collector, in particular to a dust collector capable of avoiding secondary pollution, which is used for families, offices, hotels, large halls and the like, and is particularly used for high-end people residences or office places.
According to the invention, the main machine of the dust collector is not in the same space with a room needing dust collection, but is separated by the space, so that dirty air discharged by the dust collector cannot be fed back to the room needing dust collection, secondary pollution can be avoided, operators can avoid sucking turbid air discharged by the dust collector, and noise emitted by the dust collector is avoided.
In particular, according to the invention, the dust suction corrugated hose of the dust suction pipe is longer than that of the traditional dust collector (for example, 10-20 m), but a low-pressure remote control method can be adopted, the main machine of the dust collector can be conveniently opened and closed in a remote control way, and the environmental protection requirements of cleanness, sanitation, high efficiency, energy conservation, safety, low noise and the like can be met.
Technical Field
In the prior art, the hose of the dust collector is only 1.5 meters generally, and the operator of the dust collector is beside the dust collector.
In the prior art, a turbine blade which runs at a high speed is used for generating negative pressure in a dust suction pipe, visible garbage and dust are sucked away through the dust suction pipe, large-particle dust and garbage are left in a filter screen bag, and small-particle dust and the like are discharged into a room at a high speed, as shown in figure 1. The filtering capacity of the filter screen is very limited, and tiny particles, formaldehyde, harmful gases, mould fungi and the like can be discharged back to the room from the exhaust port of the dust collector; the large volume and high velocity of the exhaust air can cause the originally relatively stationary space to become unusually turbid and, as a result, the operator of the cleaner will draw in this turbid air. Severe discomfort can be caused if the operator of the cleaner is allergic; asthma patients may develop the disease immediately; even if healthy operators without anaphylaxis inhale dirty air which is much more turbid than before dust collection, some people often have no help when wearing the mask because the dust collector is operated to cause asthma attacks. The filter screen can not filter the micro-particles and the mask can not filter the micro-particles; the concentration of the pollution particles discharged by the dust collector is higher than that of the static air in the original room, and the high-speed turbid air discharged by the dust collector becomes full of the room; microparticles are difficult to expel after inhalation into the lung and are more harmful.
In the prior art, a split type dust collector is conceived, a filter screen is connected in series with a dust collecting pipe which is left for indoor operation, and special vacuum generating equipment and a machine room thereof are built outdoors. Such vacuum equipment needs to be redesigned, the manufacturing and selling cost is high, the vacuum equipment is not movable, a large number of users have to abandon the original dust collector, huge waste is caused, and large capital investment is needed. Because the basic concept is not feasible and the market promotion is hopeless, the split type dust collector in the prior art is bound to be abandoned.
No one has long recognized that secondary pollution of a vacuum cleaner is not an attempted solution, but rather a technical problem that must be solved, and no one has considered how to solve such a problem at low cost, in a manner that is easy to implement and acceptable to the user at large. Under the guidance of the traditional inertial thinking, no one considers the following technical scheme: the original various dust collectors can be continuously used and still can be movably used; the method is easy to implement for new buildings and old houses; the dust collector can be lengthened to each corner of a room conveniently to be cleaned by connecting one or more dust collection corrugated hoses in series according to the requirement; the cost of the remote switch additionally installed on the dust collector is very low.
For the health of all levels of public affairs personnel and people, government agencies, large halls, national hotels, gymnasiums, art halls, exhibition halls, starry hotels, villas, high-end apartments, mansion and mansion for outmen, dry houses, residential houses and the like have urgent needs for dust collectors with the functions and effects.

Detailed Description
According to one embodiment of the invention, the cleaner is placed outdoors in a yard, balcony, patio, or terrace, preferably more than 60cm from the wall; the lengthened corrugated hose of the dust collector is fed into a room through a special wall hole (or a window or a door is opened and a seam is reserved). The remaining gaps are preferably blocked by curtains, curtains or the like to prevent the exhaust gas from flowing back through the dust collector. In one embodiment, a remote power switch system controlled by low voltage is installed inside the cleaner, the power supply of the cleaner is plugged in, the remote switch of the cleaner is turned on, whether the remote switch of the cleaner is effective or not is checked, and if all the functions are normal, the next step is operated. The working suction head to be cleaned is selected, the remote switch of the dust collector is pressed, the dust collector can work, and the dust collector stops working when the remote switch is released.
In another embodiment, a separate switch device box is provided, the power plug of the dust collector is inserted into the switch device box, then the power plug of the switch device box is inserted into a 220V standard power socket in a room, whether the remote control switch on the dust collector rod can normally start the dust collector is checked, and if all are normal, the next step is operated. The outdoor dust collector can work by selecting the working suction head required to collect dust and pressing the remote control switch of the dust collector, and the outdoor dust collector stops working by releasing the remote control switch.
In one embodiment, when the furniture needs to be moved, the remote control switch is released, the outdoor dust collector stops working, the furniture is moved well, and then the remote control switch is pressed, and the outdoor dust collector starts to work again immediately.
In another embodiment, when the furniture needs to be moved, the suction head stops working, and the main machine of the dust collector can temporarily stop supplying power to the dust collector when detecting the working condition, so that the energy is saved, the noise is reduced, and the service life of the dust collector is prolonged. For example, the switch device is automatically turned on when a dust suction operation is performed and is automatically turned off when a dust suction operation is not performed by sensing a pressure between the suction cup and the surface to be cleaned. Those skilled in the art can design specific circuits based on this concept, and will not be described herein.
For a new decorated house, the dust collector placed outdoors according to the invention can greatly reduce harmful substances and peculiar smell left by formaldehyde, paint, coating, glue and the like in a building. The operator of the cleaner, the person with allergic constitution or asthma, the old and the weak, and the baby have no discomfort. In summary, the vacuum cleaner according to the invention is a clean, healthy, hygienic, efficient, energy-saving, safe, low-noise vacuum cleaner.
At present, the dust catcher is various, including conventional 220V interchange dust catcher, wireless dust catcher that charges, intelligent dust absorption sweeper etc. but the theory of operation of all kinds of dust catchers among the prior art is unanimous basically, and in fact, as shown in figure 1, only visible thing has entered the filter screen, can pierce through the tiny particle of filter screen, still has got back to the room with higher speed, and fly in full house from static, can also smell the person's of chocing peculiar smell that the dust catcher discharged, what the people who operates the dust catcher sucked is this kind of air that is stained. The problem of secondary pollution of the dust collector is not solved internationally.
If the formaldehyde is contacted for a long time with low dosage, chronic respiratory diseases can be caused, and the physique reduction and chromosome abnormality of the newborn can be caused. If exposed to high concentration formaldehyde for a long time, the formaldehyde has toxic and harmful effects on nervous system, immune system and liver, and can cause carcinogenesis of nasal cavity, oral cavity, nasopharynx, skin and digestive tract.
For a new decorated house, volatile organic compounds can induce stimulation of eyes and respiratory tracts, causing headache, dizziness, visual impairment, memory impairment, cancer and the like; benzene volatilization from glue, paint and plywood can cause acute benzene poisoning of central nerves, mild benzene poisoning can cause headache, dizziness, nausea, vomiting and the like, and severe patients can have respiratory circulation failure and ventricular fibrillation; radiation hazards in natural stone can generate in vivo radiation and in vitro radiation; radon radiation damage to humans accounts for over 55% of all radiation damage to humans during their lifetime, the first leading "killer" of human lung cancer, which is classified by the world health organization as one of the 18 carcinogenic substances.
As shown in figures 2, 3 and 4, the invention overcomes the inertia of the traditional thinking, gets rid of the prior technical bias, realizes that the secondary pollution caused by the dust collector during the operation is the technical problem which needs to be thoroughly solved, therefore, the dust collector (together with the filter bag) is separated from the room needing dust collection in space, the dust collector is placed outdoors or in non-living areas such as a parking garage, and then is connected to each room by the dust collection corrugated hose; an air suction opening (a socket with a dust collection corrugated hose) and a remote control switch of the dust collector (a large current loop for driving the dust collector by small current) are arranged and are closed when not in use; when dust is required to be sucked, the air suction port and the remote control switch are opened, the air suction pipe is inserted, and the dust collector starts to work, so that all garbage, dust, formaldehyde, harmful gas, glue and the like are conveyed from the indoor to the outdoor, and the indoor is cleaned, and secondary pollution caused by the dust collector is avoided.
In the first embodiment, the dust collector is placed outdoors, a dust collection pipeline is laid in each room, a dust collection corrugated hose air inlet is arranged in each room, a dust collector starting switch (a remote control switch or a microswitch) is arranged at the same time, a dust collector power supply is plugged when dust collection is needed, and a dust collector corrugated hose air inlet is opened; after finishing sucking, turning off the power supply and turning off the air suction inlet; the room is changed and repeated again, thus thoroughly solving the problem of secondary pollution of the dust collector, sending garbage, dust, harmful gas, mites, mould, micro-particles and the like to the outside, and leading the indoor air to be cleaner and cleaner. In particular, the technical solution of the present invention can be applied in newly built high-end apartments, villas, halls, government office buildings, gymnasiums, dry resorts, exhibitions, for example.
Some cleaner manufacturers have attempted to solve the secondary pollution problem, and some cleaner manufacturers even call PM2.5 particles filtered (filter screens get clogged quickly, which increases motor load). However, how to solve the problems of particles smaller than PM2.5, harmful gas, formaldehyde, mites and mould is still unfortunate. In particular, there is no published document on how to avoid secondary pollution when using a vacuum cleaner for families with allergic constitution.
In the second embodiment, for most of the well-finished residential houses, the renovation cannot be carried out any more, but according to the research results of the inventors, the transmission pressure loss of the gas in the corrugated pipe is very small. Therefore, in the invention, as shown in fig. 2, the main cleaner body is placed outdoors, and the corrugated hose with the length of 10-20 meters is used for communicating the main cleaner body with the room for dust collection; a low-voltage low-current remote control switch system is arranged at the outer side or the inner side of the corrugated hose so as to remotely control the operation and the shutdown of the dust collector; the remote control switch can be arranged at a hard bent pipe at the tail end of the dust collection rod and can be turned on and off by a user operating the dust collector according to needs; the vacuum cleaner pipeline can select hoses (preferably 10-20 meters) with different lengths according to the indoor area size, so that the hoses penetrate through the wall or enter the room from a door window or a door gap, and other gaps are blocked by other things. Therefore, the dust collector is arranged outdoors, the suction pipe is arranged indoors, and garbage, harmful gas, formaldehyde, mites, mould and dust sucked by the dust collector are conveyed outdoors in a unified way, so that the problem of secondary pollution caused by the fact that the dust collector is arranged indoors for work is thoroughly eliminated, and the indoor environment is cleaner and cleaner; meanwhile, the original indoor dirty air is sent to the outside, and fresh air is supplemented from the door and the window, so that the indoor air is cleaned, and the indoor air is replaced once.
According to the dust collector, the special suction head is replaced, the mattress and the bed sheet can be sucked, the bed sheet can be sucked cleanly, the dandruff and the body debris are all sent to the outside without leaving traces, and on the contrary, if the bed sheet is brushed by a hairbrush, the hairbrush is found to be full of dandruff, body debris and creeper; and another special suction head can suck dust on the blanket and the wall.
In a third embodiment, the vacuum cleaner according to the invention can be remotely controlled, and a remote switch can be used to control the solid state relay, for example, a low voltage (3-30V) DC power control block 10-20A solid state relay can be used to drive the vacuum cleaner. Therefore, 3V direct current can be used as a control power supply, the device is safe and convenient, the remote control switch is pressed when dust is required to be sucked, when furniture is moved, the suction head temporarily has no pressing force on the surface to be sucked, and the remote control switch can be designed to automatically recover, so that the dust collector automatically stops working; when dust collection is not needed, the remote switch can be released, and the dust collector stops working. Therefore, the dust collector can rest, the utilization rate of the dust collector is improved, and electricity and energy are saved. In addition to the solid-state relay controlled by a wired remote switch, the solid-state relay may also be remotely controlled by radio.
According to the invention, the dust collector is placed outdoors, and the noise generated when the high-speed motor drives the turbine to rotate in the dust collecting room is obviously reduced.
The remote control switch comprises a low-voltage direct current driving circuit, wherein a high-power and high-current circuit is triggered by low voltage and low current to replace a traditional manual switch, so that electric arc can not fly, and the remote control of the dust collector is realized; the remote control voltage is low voltage, the dynamic range is large, and the voltage ranges from direct current 3-30V to safe use voltage;
according to the invention, the pressure loss of air in the lengthened bellows is very small, and the problem that a large number of old houses cannot be provided with fixed dust suction pipelines at present and actually the problem that dust suction is seriously needed to cause secondary pollution is solved.
In the prior art, a central dust collector is adopted, and a dust collecting pipeline with the diameter of 50mm is embedded in a partition wall, but for a wider old building, plastic hard pipes with the diameter of 50mm cannot be embedded in brick walls and floor slabs; for new buildings, the cost is too high, and the market popularization is difficult.
On the contrary, the invention has low implementation cost, is easy to be adopted in old buildings, the original dust collector can be continuously used, the corrugated drain pipes of the washing machine are mutually inserted, the dust collection hose can be lengthened by 10 to 20 meters, the pressure loss of the dust collector is very small, and the dust collection effect is almost the same as that of the original dust collection hose with the length of 1.5 meters.
In the prior art, half an hour to one hour is required to start a dust collector; in the invention, if the outdoor hand is used for operating the 220V high-voltage switch to control the dust collector, the operation is inconvenient and unsafe, and the invention uses a simple and low-cost circuit to realize the wireless and remote control of the outdoor dust collector indoors.
As shown in FIG. 5, in one embodiment of the present invention, the suction cup 2, the dust collection pipe 6, and the plurality of dust collection hoses 4 connected in series are placed in a room with the wall 3 as a partition; while the main body 1 and the filter bag 5 of the cleaner are placed outdoors. The dust collector can be a common household dust collector, the economic burden of a user does not need to be increased when the dust collector is implemented, and economic loss caused by the fact that the dust collector is eliminated.
The dust collection hose 4 can adopt a corrugated drain pipe of a washing machine, and the length of each section of the dust collection hose 4 is about 1.5 m. Depending on the furthest distance of suction in the room from the hole 12 of the suction hose through the wall 3, the lengths of suction hose 4 can be connected in series to a total length of 10m, or even 20 m. In the invention, under the condition that a plurality of sections of dust collection hoses 4 are connected in series, a dust collector or a filter is not suggested to be connected between two adjacent sections of dust collection hoses 4 in series, and the 'convenience' brought by the dust collector or the filter is not seen so as to prevent indoor pollution caused by accidental disconnection of the two adjacent sections of dust collection hoses 4. In addition, under the condition of two lengthened dust collection hoses 4, two adjacent dust collection hoses 4 can not be accidentally disconnected, and a dust collector or a filter can be connected between the two adjacent dust collection hoses 4 in series, so that convenience can be brought, and indoor pollution cannot be caused.
According to the present invention, the cleaner body 1 is placed outdoors, but the operator does not need to frequently go outdoors to operate the cleaner body 1 because the present invention can remotely control the cleaner body 1 outdoors on the hand-held cleaner handle 6. Specifically, the switch control device 11 of the present invention is electrically connected with the main machine 1 of the vacuum cleaner, the power supply 13 (such as 220V ac power supply) and the remote microswitch 7 respectively. Wherein, the switch control device 11 is provided with a switch device 89, the switch device 89 is provided with a capacitor 80 and a pair of power contacts 9, the capacitor 80 is electrically associated with the pair of electric contacts 9, the pair of electric contacts 9 are plugged on the power supply 13 through a power plug 10, and the main machine 1 of the dust collector is connected in series in the circuit 9 between the pair of electric contacts 9 and the plug 10; a low-voltage control power supply 8 of a capacitor 80 is also arranged in the switch device 89, and a remote-control microswitch 7 is arranged at the joint of the dust collection hard pipe 7 and the dust collection hose 4; the microswitch 7 and the low voltage control power supply 8 form a charging circuit of the capacitor 80, and the capacitor 80 is charged or cut off by a low voltage direct current circuit.
The microswitch 7 is connected in series in the low voltage dc charging circuit, driving the capacitor 80 with a micro current. The connecting line between the microswitch 7, the low voltage control power supply 8 and the capacitor 80 can be attached to the corrugated suction pipe 4, preferably arranged on the outer surface of the dust collector hose 4 or in the dust collector hose 4; alternatively, the charging circuit may be controlled wirelessly, and the wireless signal transmitter 71 is provided at the microswitch 7, and the wireless signal receiving device 81 is provided at the low-voltage control power supply 8.
When the microswitch 7 is closed, the low-voltage direct-current circuit charges the capacitor 80, so that the switching device 89 and the 220V alternating-current power supply 13 form a loop, and the main machine 1 of the dust collector is started; when the microswitch 7 is opened, the low-voltage direct-current circuit is disconnected, the capacitor 80 loses charge, the switching device 89 is disconnected from the 220V alternating-current power supply, and the main machine 1 of the dust collector is stopped. Preferably, the switch device 89 is automatically turned on during a dust suction work and is automatically turned off when a dust suction work is not performed by sensing a pressure between the suction cup 2 and the surface to be dust-sucked.
In fig. 4-5, the remote switch 7 has a safe low voltage, and the 10-20A large current conduction of the dust collector is driven by micro current, tests prove that enough power is enough for controlling one dust collector, and the control power supply of the remote switch 7 adopts 3-28V voltage to be very safe. Tests show that the 9V standard battery can be used for about 2 years generally, and is convenient, economic and safe. The switching device 89 may be, for example, a solid-state relay, a safety low-voltage micro-current control module, or a safety low-voltage micro-current control switch.
In the test, a relay is used for driving a high-power electric appliance, for example, an operation switch with 12V safe voltage is used for controlling the high voltage of 220V or even 380V, and the coil of the relay consumes large power due to an electromagnet coil; the high-power triode is triggered by low current and low voltage, no electric contact is used for ignition, no electromagnetic coil is used, and the energy-saving and safe effects are achieved.
When the remote control switch 7 is closed, the electronic switch formed by the pair of electric contacts 9 is also closed, the dust collector 1 and the 220V power supply form a loop, the 220V mains supply supplies power to the dust collector 1, and the dust collector 1 starts to work. When the remote switch 7 is released, the electronic switch formed by the pair of electric contacts 9 is turned off, and the dust collector 1 is powered off and stops working.
Tests show that even if the inner diameter of the compressed air conveying pipe is about 12 mm, the pressure loss of air in the pipeline is very small; the air resistance of the corrugated pipe with the same inner diameter is smaller than the resistance loss of the light pipe; with the corrugated pipe with the diameter of 32mm and the length of 50 meters, the suction force in the corrugated pipe is hardly reduced; the corrugated drainage hose of the washing machine can be used as a dust collection hose, the length of a single hose can reach 30 meters or even 50 meters, a plastic pipe with the diameter of 32 millimeters can be connected with the dust collector, transition tapers can be arranged at two ends of the plastic pipe, and the plastic pipe is sleeved in the corrugated hose and is very firm.
If the high-power small switch of the 220V power supply is directly controlled by hand, the safety is very unsafe. According to an embodiment of the remote control switch 7, a relay controlled by 12V direct current is adopted to remotely control the outdoor dust collector, so that the safety is achieved, however, the electromagnet coil of the relay is driven by 12V direct current, the power consumption is high, and the battery is frequently replaced; and the relay has complex structure and high cost, can generate electric arc and generate electromagnetic interference.
In another embodiment, the washing machine has good effect and saves electricity by adopting a corrugated hose and a low-voltage control solid-state relay (SOLlD STATE RELAY or GB15600-601 relay manufactured by Hitachi company), and the 9V square battery can be used for at least more than 1 year. The solid-state relay has a semiconductor element therein, and the cost is relatively high.
According to another embodiment of the switching device of the present invention, a set of low voltage dc driving circuits is provided inside to trigger a high power transistor with low voltage and low current as a switch to be remotely controlled, since the control voltage is low voltage and the dynamic range is large, and 3-30V dc is in the safe use voltage range. In particular, the present invention utilizes the electrical association of a capacitor with a pair of electrical contacts to implement a novel electronic switch that is simple, reliable, and inexpensive.
The dust collector with the lengthened dust collection hose solves the problems that fixed pipelines cannot be installed and 50mm plastic hard pipes cannot be pre-embedded in brick walls and floor slabs at all in a large number of houses at present, and solves the defect of secondary pollution caused by squeak dust collection at low cost.
At present, the power of the household dust collector is 800- & gt 1400W, a washing machine water outlet hose which is about 32mm in diameter and is not cut and is 10-30 meters long can be used as the dust collection hose 4, while the diameter of the hose of the household dust collector 1 is about 40mm, so that the air is reduced from 40mm to 32mm, the diameter is reduced by 20%, the air flow speed of the dust collector is improved by about 50%, and therefore, the high-power dust collector can generate some noises.
To this end, a simple air flow rate dispenser comprising a dispenser body plastic tube 100 of about 200mm length may be installed at the junction of the washer hose 32mm to the vacuum cleaner 40mm as shown in FIGS. 6A-6D.
The first end 101 and the second end 103 of the plastic pipe 100 of the blending main body are respectively provided with a small taper 102 and a small taper 104;
the diameter of the first end 101 is slightly smaller than 40mm (in a frustum cylindrical working condition) or 32mm (in a cylindrical working condition, the end part of a dust collector hose with a necking hard pipe) and is used for connecting a hose of 40mm of a dust collector;
the diameter of the second end 103 is slightly smaller than 32mm, and the second end is used for connecting a corrugated hose with the diameter of 32 mm;
the middle position of the plastic pipe 100 of the blending main body is provided with 2 blending holes 105 and 106 which are about 20mm apart and have the diameter of about 8-10 mm;
in addition, the plastic pipe 100 for preparing the main body is also provided with a section of plastic preparing sleeve 200 with the inner diameter of 32mm and the length of about 100 mm.
An inclined notch 201 is provided at an angle of about 15-20 degrees to the longitudinal axis of the plastic dispensing sleeve 200, so that the plastic dispensing sleeve 200 can be sleeved on the outer surface of the plastic pipe 100 of the dispensing body having a diameter of about 32mm and two dispensing holes 105, 106, and the size of the area of the dispensing air inlet hole can be adjusted in two directions along the direction indicated by the arrow X-X, so as to eliminate noise.
Experiments show that by adopting the air flow rate regulator, the air flow areas between the regulating holes 105 and 106 and the outside are slightly reserved, so that some air is slightly leaked, the dust collection effect is not obviously reduced, and the noise at the dust collection opening can be obviously reduced or even eliminated. For example, when the vacuum cleaner 1 is placed on a terrace of the third floor under a state of no noise, smooth soybeans, mung beans and peanuts placed on the ground of the first floor can be easily sucked into the vacuum cleaner 1 of the third floor.
In another embodiment, the diameter of the corrugated hose of the dust collector is about 40mm, and two hard plastic pipe joints are arranged at two ends of the corrugated hose; the bayonet 101 at one end of the plastic pipe 100 of the blending main body and the corrugated hose of the dust collector can be conveniently and quickly assembled and disassembled, the buckle 103 at the other end can be quickly connected with the hard plastic dust collection pipe, the connecting port is just a conical hole with the diameter slightly smaller than 32mm, and the hard plastic dust collection pipe can be inserted into the conical hole during dust collection, so that the plastic pipe is convenient to assemble and disassemble. The diameter of the corrugated hose of the washing machine is slightly smaller than 32mm, so that a small cone 104 is machined at the two ends of the plastic pipe with the diameter of 32mm and can be just inserted into the corrugated hose of the washing machine.
In one embodiment, the connection of a 40mm diameter dust collector hose and a 32mm diameter drainage corrugated pipe for a washing machine can be conveniently realized by processing a chamfer at two ends of a section of 32mm diameter plastic pipe, and if a dust suction port is noisy, a plurality of 2mm diameter leakage holes are used, and the noise can disappear.
In one embodiment, the diameter of the dispensing holes 105, 106 isAt 8mm, about half of the opening, the noise disappears. The area of the 40mm diameter hole is about 1256mm2The area of the 32mm diameter hole is about 803mm2The area of the hole with a diameter of 8mm is about 50mm2Even if the hole with the diameter of 8mm is fully opened, the total area of the corrugated hose of the dust collector is about 853mm2Compare area 1256mm of 40mm diameter hole2And about 403mm more2Therefore, the dust suction force is not reduced. Thus, the diameter of the dispensing orifice can be as high as 8 mm.
The dispenser set 200 may be made of the same plastic tubing having a diameter of 32mm and a wall thickness of about 1.7mm as the dispenser body 100. After the adjusting sleeve 200 is cut into the gap 201, the adjusting sleeve 200 is wrapped outside the plastic pipe of the adjuster main body 100, the wrapping force is large, the contained contact area is large, the rotating friction force is large, a certain external torque is needed to enable the adjusting sleeve 200 to rotate, and after manual adjustment, the fixed position is stable, and circumferential or circumferential displacement cannot be generated due to vibration.
In another embodiment, the inside diameter of the corrugated plastic tube of the washing machine is slightly smaller than 32 mm; one end of a hose with the diameter of 40mm of the dust collector is connected with the hard plastic quick bayonet of the dust collector, and the other end of the hose is connected with a conical hole with the diameter slightly smaller than 32mm of the portable dust collection hard pipe, so that two ends of the hose with the diameter of 32mm are conveniently connected by respectively processing a cone at the two ends of the plastic pipe with the diameter of 32 mm; thus, the tapered adapter body 100 is not required at all.
For a newly-built building, a hard plastic pipe with the diameter of 50mm can be pre-embedded in the wall and the ceiling of the building, and a dust collector is placed outdoors, so that the problem of secondary pollution of the dust collector is thoroughly solved; however, old houses cannot be modified to add dust collection pipes. According to the invention, the original dust collector can be slightly modified, and the problem of secondary indoor pollution of the dust collector is solved by using the lengthened corrugated hose.
Currently, the present invention helps to achieve indoor air circulation, keep clean and fresh.
At present, places with a large number of public population, such as halls, movie theaters, exhibitions, offices, research institutes, laboratories and the like, have fresh air supply and return equipment, but the equipment far exceeds the height of people and the range of motion of people. In the activity space of people below two meters, the carbon dioxide exhaled by people is heavier than air and is left in the activity space of people, more serious is below one meter, the places under tables, chairs and cabinets, which are close to the ground, are in shade places, have no sunlight places, and are poor in ventilation conditions, so that mites, molds and the like which cannot be seen by naked eyes are most easily bred and hidden, the broom cannot sweep away, the dust collector cannot suck the places, and the dust collector can also spray polluted particles into the air from an air outlet to form secondary indoor pollution of dynamic harmful substance floating, but the secondary indoor pollution is not valued in the market so far.

The vacuum cleaner of claim 7, wherein when said remote switch is closed, said low voltage dc circuit charges said capacitor such that said switching device and said 220V ac power source form a power controlled loop, whereby said vacuum cleaner is activated; when the remote control switch is turned on, the low-voltage direct current circuit is disconnected, the capacitor loses charge, the switch device is disconnected from the 220V alternating current power supply, and the dust collector is stopped (preferably, the switch device is automatically switched on during dust collection operation and is automatically switched off when dust collection operation is not performed by sensing the pressure between the suction cup and the surface to be collected).
9. Method according to claim 8, characterized in that the remote control switch, the battery compartment of the remote control switch, the switching device, the connection lines between the capacitors are attached to the bellows tube (preferably on the outer surface of the bellows tube or in the bellows tube); or a wireless signal transmitter is arranged at the remote control switch, and a wireless signal receiving device is arranged in the switch device.
10. A method of cleaning a room to avoid secondary pollution by using a cleaner as claimed in any one of claims 1 to 9, the cleaning location being under a table, a chair, a cabinet, or a floor, in addition to the floor, a carpet, or a wall; the space above the ground in the shade; and a space above the ground with poor ventilation conditions, characterized in that: the main machine of the dust collector is arranged outside a dust collection room, so that waste gas discharged by the dust collector cannot flow back into the room;
remotely controlling a remote switch device by low voltage, small direct current, wire or wireless; the traditional large-current switch directly operated by hand is changed into a small-current switch operated by hand; the micro-current button replaces the traditional manual heavy-current switch (the conventional household dust collector is frequently started and stopped by the manual heavy-current switch when being started and stopped, the service life of the switch is shortened, the dust collector idles when moving furniture, consumes electricity, shortens the service life of dust collection, has low utilization rate, is easy to strike fire and has potential safety hazard);
preferably, the corrugated hose tends to unwind from a movable reel when it is pulled and to automatically wind on said reel when it is unwound; all the dust collection corrugated hoses are sequentially connected in series, or the whole lengthened washing machine drainage corrugated hose is adopted; the dust filter screen, the dust collector or the filter bag are arranged outdoors and are not left indoors (so as to prevent indoor pollution caused by accidental disjointing of the filter bag); more preferably, the user does not eliminate the vacuum cleaner in use but modifies it, does not construct an outdoor dust-collecting machine room, and does not need a special vacuum-cleaning device (preferably, the dust-collecting hose is connected in series in multiple stages, and the total length of the dust-collecting bellows hose is appropriate according to the size of the room).
