Utility model content

The utility model provides a kind of cleaner for clean indoor equipment, to solve the non-dust cloth in toilet Wipe the problem of bad to the dust removing effects of equipment, existing cleaner is not suitable for equipment cleaning in toilet.

The technical solution adopted in the utility model is as follows:

A kind of cleaner for clean indoor equipment, including pressure-vaccum head, vacuum pump group and it is set to pressure-vaccum head and vacuum Pressure-vaccum pipe group between pump group；The vacuum pump group at least contains a vacuum pump；The center of the pressure-vaccum head is provided with air blowing Runner；Several air-breathing runners are evenly arranged with around air blowing runner on the pressure-vaccum head；The pressure-vaccum pipe group includes and air blowing The gas blow pipe of runner connection and the air intake duct being connected to each air-breathing runner；The gas outlet of the gas blow pipe and any vacuum pump It is connected；Having heaters and air blowing filter are set gradually along gas flow direction on the gas blow pipe；The air intake duct with appoint The air inlet of one vacuum pump is connected.

The working principle and the course of work of the technical program are as follows:

Firstly, it is necessary to it is clear that, the technical program intermediate pump is a kind of rotated conducive to impeller so that air generates stream Dynamic existing equipment；It is provided with air inlet and air outlet, the negative pressure of vacuum generated by the rotation of impeller, so that outside air Out of air inlet sucking vacuum pump, and generated centrifugal force is rotated using impeller, the air of sucking is discharged from gas outlet； The power of usual vacuum pump is bigger, and the suction generated is bigger, and the flow velocity that air is discharged is higher；Because of its air-breathing venting principleand and Self structure and control method are the prior art, therefore this will not be repeated here.Secondly, its role is to heat about heater The air of heater is flowed through, so that air heats heat up, structure can be but be not limited to the resistive heater of coiling, and pass through The in-fighting that access DC power supply is run through resistance converts electrical energy into thermal energy, this has had a large amount of utilizations in the prior art, Therefore this will not be repeated here；Certainly, in view of in toilet by the temperature resistant capability of cleaning electrical equipment and to the heating of dust particles Removal effect, by repetition test, the watt level of heater is excellent so that the temperature of heated air stream is no more than 50 DEG C and is advisable Select temperature within the scope of 40~50 DEG C.In addition, how to connect with multiple air-breathing runners about air intake duct, water delivery engineering can be referred to The shunt method of middle water pipe is configured, and belongs to the prior art, and corresponding example has also been made in illustrations, therefore It does not repeat them here.Finally, gas blow pipe filter, its role is to filter dust particles entrained in adsorption purge gas, structure It can be constituted for multi-layer nonwoven fabrics, or ceramic filter grid also or polymer adsorption film, but is not limited to above-mentioned act Example structure；Again since the filter device of dust particles, equipment or device belong to the prior art, therefore do not repeat them here equally.

It is emphasized that in the technical program, although not to the specific electric connection mode of the electrical equipment and its Control method is described, but according to above-mentioned analysis it is found that these electrical equipments belong to existing equipment, and in this technology side Its existing function is played in case, in particular, function used in vacuum pump is pump drainage air to form air stream, heater Used function is to heat to substance.And above-mentioned function is documented in detail in the prior art, therefore it is specific Embodiment can be carried out referring in particular to the prior art, especially when the circuit connection and electrical equipment control for designing above-mentioned two component When.

In the course of work, connects external power supply and make cleaner access power supply and enter working condition.When entrance work shape After state, vacuum pump is started to work, and impeller starts to rotate, and gets rid of the air acceleration entered inside vacuum pump while generating suction Out；By the size of design control input power, the size of the output power of vacuum pump can be controlled, to obtain difference simultaneously The suction and air of intensity throw away speed；Significantly, since in the technical scheme, the air inlet of vacuum pump is connected with Air intake duct, gas outlet are connected with gas blow pipe, and therefore, the suction that vacuum pump generates can be conducted by air intake duct to pressure-vaccum head, and Negative pressure field is formed in the end of each air-breathing runner, and the air stream being thrown out of can equally flow to pressure-vaccum head by gas blow pipe, from And purge gass are formed in the end of air blowing runner.Again since air-breathing runner and air blowing runner are to be disposed adjacent, can blow The end of suction nozzle forms a stable air flow field；In this air flow field, by blowing for quickly flowing of throwing away of vacuum pump Scavenging is flowed out from air blowing runner, is then recycled back to vacuum pump from air-breathing runner under the influence of negative pressure field.The same time, due to The connection of power supply, heater also synchronize and start to work and the temperature of purge gass is made to increase.It is removed when needing to carry out equipment cleaning When dust particles, by the terminal surface of pressure-vaccum head close to the workspace for needing dedusting.At this point, the purge gass meeting blown out from air blowing runner It is applied on workspace, using the heat effect of own temperature, so that dust particles heat up, so that the surface of dust particles It can rise；Adhesive capacity decline between the dust particles that surface can rise, with workspace surface, thus the work of atmospheric pressure Fugitive dust is formed with lower disengaging workspace surface and is entered in purge gass；With purge gass by workspace surface blocking and four When each air-breathing runner of entrance that overflows is formed by negative pressure field areas, carrier's dust particles are formed by fugitive dust with negative pressure field naturally Air-breathing runner is flowed into, the pump chamber of vacuum pump is then recycled back to by air intake duct；When one carries the purge gass of dust particles for this It is thrown away again by vacuum pump after entering gas blow pipe from gas outlet, when by air blowing filter, dust particles therein are blown Air filter absorption so that purging device is clean once again and is blown out again by air blowing runner, with continue to workspace surface into Row cleaning；It recycles repeatedly, has been finally reached and clean purpose is carried out to workspace surface.

Side during above-mentioned clean work area surface dust particle, with the common non-woven fabrics wiping in existing toilet The method that method is dusted is different.The former is easy to produce electrostatic if direct xerotripsis and may cause the scuffing on workspace surface, And it is not in place to the control of fugitive dust, air can partially be diffused into again by wiping the dust particles to get off, easily cause secondary pollution；As It improves, has and the easy volatile solvents such as alcohol wetting non-woven fabrics is selected to be wiped, control fugitive dust to a certain degree in this way and reduce Friction between working face, but solvent volatilization needs the time, and residual solvent may threaten the operating of equipment, if furthermore primary Less clean position, remaining dust particles are easier to bond fouling with workspace surface under the action of the solvent.And this technology side Case makes to be attached to work by the principle of gas purging suction using the percussion that high-speed air generates workspace surface The dust particles on area surface are detached from and form fugitive dust with the drive of purge gass, then generate the negative pressure that suction generates using vacuum pump Fugitive dust area periphery by air-breathing runner in formation forms negative pressure field, so that fugitive dust can be empty under the action of negative pressure Gas, which stays, takes back vacuum pump, and is further insufflated filter and is adsorbed and removed；During this, due to only having air and workspace table Face contact, thus there is no to workspace surface scratching the problem of.In addition to this, it only acts on, makes by the purging of air The ability that dust particles fall off is significant not enough, therefore is provided with heating also on the route of gas blow pipe in the technical scheme Device enables the surface for the dust particles for tightly investing workspace surface to rise, to make the latter more by the heating to purge gass Easily it is detached from.I other words the purge gass in the technical program, are provided simultaneously with the double function of purging and heating, exactly the two function The combination of energy, so that it is significant to the cleaning effect of dust particles.In addition, being blown in the technical program by the addition of heater Device is swept with certain temperature, one side can play the function of promoting dust particles to be detached from, on the other hand again can be as one kind The means for assisting dehumidifying, are dried the surface of workspace.The benefit of this desiccation is mainly reflected in terms of two: one It is, so that gluing the obstinate dust drying sticked in workspace surface due to wetting action and being easier to blow down；Second is that can be used as makes Secondary cleaning after being cleaned with the non-woven fabrics of wet with solvent enables to solvent for use thoroughly to volatilize in secondary cleaning Without remaining, so that dust particles be avoided to adhere to, and then the thorough cleaning on workspace surface is realized.And above-mentioned function is also existing General deduster or dust suction especially under the action of single vacuum pumps, are formed simultaneously purging and suction two not available for it A movement, substantially reduces the volume of cleaner, while significantly reducing the power consumption of cleaner.

Further, the number of the vacuum pump group intermediate pump is 1；The gas outlet of the gas blow pipe and vacuum pump is The blowing end of vacuum pump group；The air intake duct is connected with the air inlet of vacuum pump.When vacuum pump group only includes a vacuum pump When, realize that air-breathing required for cleaning function and air inlet function are realized by the same vacuum pump.At this point, cleaner can consume energy Relatively small degree is arrived in enough control, to realize energy-efficient purpose；At the same time, the volume and weight of vacuum pump are opposite Smaller, so that the cleaner volume and weight of designed manufacture also decreases, this has been considerably improved the convenience of cleaner.

Further, the number of the vacuum pump group intermediate pump is two, including the second vacuum pump and third vacuum pump； The air intake duct is connected with the air inlet of the second vacuum pump；The gas outlet of second vacuum pump, which is provided with, to be in communication with the outside Vacuum pump discharges pipe；The gas blow pipe is connected with the gas outlet of third vacuum pump；The air inlet of the third vacuum pump is arranged There is the vacuum pump air inlet pipe being in communication with the outside.For the general daily cleaning in toilet, pass through single pump realize simultaneously air blowing with The scheme of air-breathing can either meet cleaning and require, while can be effectively reduced energy consumption.But in face of large area and dust compared with Serious region, the power singly pumped may not be able to meet demands.As an improvement, by adding third vacuum pump, to be formed double Pump design.Wherein, the second vacuum pump is exclusively used in providing air-breathing power for air intake duct, and third vacuum pump is exclusively used in providing for gas blow pipe The power of purge gass., can be mutually indepedent between air-breathing and air blowing under such design, so as to more efficiently improve pump The utilization rate of power, and then more powerful air-breathing and blowing effect are improved, finally obtain better cleaning effect.It is being cleaned Essentially identical when work original example functionally is with single pump operation, it is true from different two that difference is only that purge gass and suction are generated Sky pump, therefore, no longer repeats herein.

Further, vacuum pump discharges filter is provided on the vacuum pump discharges pipe.At this point, vacuum pump discharges pipe In air be directed to the pump chamber of the second vacuum pump, that is, have the air stream of dust particles.So when cleaning starts Afterwards, in order to avoid this part dust particles enters again in toilet with discharge gas, by vacuum pump tracheae It installs vacuum pump discharges filter additional, absorption can be made to the dust particles in discharge gas, so as to avoid the latter to cleaning The pollution again of room, further improves cleaning effect.

Further, distributing T-pipe is provided on tube body of the gas blow pipe between vacuum pump group blowing end and heater Valve, the air inlet of the three-way flow divider valve and any gas outlet are connected to gas blow pipe, be connected on another gas outlet with outside The shunting exhaust tube of boundary's connection.It, can be by being set to bypass by the way that the setting of three-way flow divider valve is arranged on gas blow pipe It shunts exhaust tube to shunt purge gass, to controlledly reduce the flow of purge gass in gas blow pipe.What is done so is good Be in, widened the difference of pressure-vaccum head end air-blowing quantity and inspiratory capacity so that inspiratory capacity be greater than air-blowing quantity, with guarantee blow Suction nozzle end forms stronger negative pressure field, and then guarantees that fugitive dust caused by purging workspace surface dust particle can be inhaled It walks, to reach better cleaning action and effect.

Further, flow divider discharge filter is provided on the shunting exhaust tube.At this point, shunting exhaust tube In air be directed to work and remove surface and its air near it, that is, have the air stream of dust particles.So when clear After clean work starts, in order to avoid this part dust particles enters again in toilet with discharge gas, by dividing It flows and installs flow divider discharge filter on exhaust tube additional, absorption can be made to the dust particles in discharge gas, to avoid Again pollution of the latter to toilet, further improves cleaning effect.
