The utility model discloses the designer carries out the analysis of tracing to a great deal of shortcoming that current commonly used filter core filtration formula and electron collection dirt formula new trend clarification plant exposed in long-term use to the part structure research and development that causes to use inconveniently and install other unfavorable nature improves, and the innovation has proposed a new trend purifier who possesses self-cleaning function, with the experience that obtains the practicality stronger, new trend purifying effect is more superior, consumptive material and energy consumption are more saved.

In order to understand the innovative nature of the solution according to the invention, the following details of the structural features of the device and of the operating states of the purification method in the different phases of use are respectively described below.

In general, the fresh air purification device can be understood as a basically closed cavity and is communicated with the inside and the outside of the room through an air inlet and an air outlet. There is necessarily a fan for introducing outdoor air into the device, and as an alternative outlet for directing the air flow, there is also an alternative air valve in the device to exhaust air to the outside during maintenance or other specific phases. As shown in fig. 1 to 5, respectively, the structure improvement of the new air purifying device of the present invention is mainly: a composite purification component 2 which is used as a main core and takes sterilization and dust collection as main functions is arranged between the fan 1 and the alternative air valve, and the composite purification component has the functions of automatically spinning a waterproof breathable nanofiber membrane, automatically cleaning and the like. From the module structure, the composite purification component 2 is composed of a spinning liquid supply unit, a coating unit, a positive high-voltage generation polar filament 5, a negative dust collection substrate 6, an automatic cleaning brush 8, a waste film collection box 9 and a sensor module. The main component of the core, which replaces the traditional filter element, is a waterproof breathable nanofiber membrane 7 which is automatically formed by spinning and can automatically clean and fall off after failure, while the spinning solution used as the raw material is attached to the anode high-voltage generating polar filament 5 by a spinning solution supply unit and a coating unit which are driven by a main control part, and a nano-scale drawn wire 36 is adsorbed on a cathode dust collection substrate 6 and is formed into the waterproof breathable nanofiber membrane 7 which can clean and fall off by spinning in an disordered way. The fresh air purification device does not require protection, only meets the requirements of receiving signals, processing and operating with preset parameters and controlling the driving of asynchronous output on-off power supplies of various motors, fans, pumps and the like, and therefore, a circuit diagram and related detailed descriptions are omitted.

It is not difficult to understand, the utility model discloses the device filters the filter core ingeniously and fuses with the advantage of electronic dust collection mutually, and as the scheme of replacing the filter core moreover, not directly adopt ready-made filter screen, but built-in integrated the component that can automatic weaving shaping filter screen and can be under necessary user state automatic clearance filter screen on the negative pole collection dirt base plate to the realization lasts, keeps filter core cleanness and air purification effect high-efficiently.

From the details of the components of the composite purification assembly: first, the spinning solution supply unit is composed of a solution storage tank 31, a solution supply pump 32, a solution supply pipeline 33 and an electric heater 34. This reservoir 31 is filled with a sufficient amount of spinning solution and is maintained in the liquid state by the energization of the electric heater during operation of the apparatus. The spinning solution is a hydrophobic material and satisfies a stock solution capable of nano-scale spinning, and is driven by a liquid supply pump 32 through a liquid supply pipeline 33 to circularly flow between the coating unit and the liquid storage tank 31. As further optional optimization, a liquid level sensor can be additionally arranged in the liquid storage tank, so that when the allowance of the spinning solution is lower than the lower limit, a signal is given an alarm to remind maintenance personnel to replenish consumables.

Next, the coating unit is composed of the coating motor 41 and the coating module 42, and the coating module 42 is prepared as a precondition for spinning, in which the coating motor 41 is driven to move laterally along the positive electrode high voltage generating electrode wire and the spinning solution is coated on the positive electrode high voltage generating electrode wire 5 to form the droplet-like 35 which is slightly condensed and does not drip. Here, the positive high voltage generating electrode wires 5 are arranged laterally in parallel at intervals, and the coating modules 42 are matched one-to-one with each of the positive high voltage generating electrode wires and driven to laterally displace. And a liquid outlet is arranged in the transverse moving path of the liquid supply pipeline corresponding to each coating module and used for supplying liquid to the coating modules to keep sufficient wettability.

Furthermore, the negative dust collecting substrate 6 is seated in the waste film collecting box 9 and has a vertical rod in the middle, and the automatic cleaning brush 8 is attached to the vertical rod and is driven to clean the negative dust collecting substrate 6 from top to bottom, so that the failed waterproof breathable nanofiber film 7 falls into the waste film collecting box 9. The part mainly plays a role as a carrier for automatically weaving and cleaning the filter element substitute and separating dust, particles and the like in airflow in the actual operation process of the device.

And finally, as a basis for switching the running state of the device, a sensor module comprising a combined air quality sensor and an air pressure sensor for sensing wind resistance is arranged in the device. And because of the state detection demand before and after the compound purification subassembly is handled along the air current, this sensor module includes and locates the front end sensing module before anodal high pressure emergence utmost point silk 5 along the wind direction, locates the rear end sensing module behind negative pole dust collecting substrate 6, and the main control part presets corresponding front and rear end sensing module induction signal difference range of judging waterproof ventilative nanofiber membrane inefficacy. The air quality sensor includes but is not limited to devices for detecting the content of PM2.5, carbon dioxide, oxygen, hydrogen sulfide, ammonia odor and the like.

As can be seen from the schematic block diagram shown in fig. 2, after the untreated outdoor air (containing bacteria, viruses, small flying insects, water vapor or small droplets) enters the device, the high voltage is generated around the filament array by the high voltage of the positive electrode, so that bacteria, viruses, small flying insects and the like in the air can be killed and carbonized, and meanwhile, the dust particles in the air are positively charged after passing through the high voltage electric field of the positive electrode; the air after the positive high-pressure treatment reaches the waterproof breathable nanofiber membrane, the waterproof breathable nanofiber membrane is formed by weaving nano-wires with extremely small diameters, dust particles or carbonized substances in the air can be blocked, meanwhile, the wires forming the waterproof breathable nanofiber membrane are formed by weaving hydrophobic materials, the diameters of the wires are very small, a plurality of tiny pores are formed in a woven net for gas to flow through, and the pores are far smaller than the size of water drops, so that water vapor and small liquid drops can be effectively blocked outside the waterproof breathable nanofiber membrane, and the waterproof breathable effect is achieved.

If a hole appears in the waterproof breathable nanofiber membrane in the using process or the density of a certain part of the waterproof breathable nanofiber membrane cannot meet the requirement during spinning, part of micro-dust particles can escape. At the moment, because the escaping dust particles have positive charges, the dust particles are firmly adsorbed when passing through the high-voltage negative generating pole plate, and thus, the dried and purified air can be obtained. In order to monitor whether the working state of the fresh air purification device is normal or not, front and rear end sensing modules are respectively arranged in front of and behind the composite purification assembly and used for feeding back air quality to the main control part and automatically judging whether the waterproof breathable nanofiber membrane is invalid or not.

On the basis of the description of the clear and complete device structure improvement embodiment, the state characteristics of the fresh air purification device in different stages during working and operation are further understood, the fresh air purification device mainly comprises three stages of operation processes of waterproof breathable nanofiber membrane spinning, sterilization and dust removal and automatic cleaning, and the requirements of automatically responding to air outlet change and switching the operation processes can be basically met.

As shown in fig. 3, 4 and 5, in the spinning stage of the waterproof and breathable nanofiber membrane, the fan is controlled to stop rotating, and the alternative air valve is switched to the outdoor channel, so that the smell of the spinning solution or the nano-filaments is prevented from being blown into the room. And then spinning is performed in an environment with no or weak air flow. Specifically, the electric heater starts to work to heat the liquid storage tank, the spinning solution is heated and kept in a liquid state in the liquid storage tank and the liquid supply pipeline communicated with the liquid storage tank, the spinning solution is driven by the liquid supply pump to be sent to the coating unit through the liquid supply pipeline, and redundant spinning solution flows back to the liquid storage tank to be recycled. And starting a coating motor to operate, and transversely moving the coating unit on the positive high-voltage generating polar filament and coating the spinning solution. Because the anode high-voltage generating polar wire is connected with the anode high voltage, and the cathode dust collecting substrate is connected with the cathode high voltage, the liquid drops of the spinning solution are also provided with positive charges, and are adsorbed to the cathode dust collecting substrate in a nano-scale wire drawing manner under the action of the electric field force of high-voltage static electricity, the tension of the liquid drops and the gravity, and finally the waterproof breathable nanofiber membrane is formed by disordered spinning.

Since the weaving process is influenced to a certain extent by the effect of gravity, necessary distribution adjustments are also proposed for the feed strength of the aforementioned coating units in order to maintain the web-wise uniformity of the resulting waterproof breathable nanofibrous membrane: the high-voltage generating electrode wire is transversely and uniformly distributed along the length direction of the positive electrode high-voltage generating electrode wire, and the vertical direction vertical to the length is distributed in a descending manner from top to bottom. The quantity of the liquid drops coated on the uppermost or the last positive electrode high-voltage generating electrode wire is large, the quantity of the formed drawn wires is relatively large, and the quantity of the liquid drops coated on the lower or the last positive electrode high-voltage generating electrode wire is small, and the quantity of the liquid drops can be adjusted and set according to the width of the electric field.

When the weaving of the fiber membrane is finished on the negative electrode dust collecting substrate, the operation state can be switched to a sterilization and dust removal stage. At this time, as shown in fig. 6, the fan is started to operate, outdoor air is pumped into the device for waiting for treatment, the spinning liquid supply unit, the coating unit and the automatic cleaning electric brush are all stopped to operate, and the alternative air valve is switched to an indoor channel so as to send out purified fresh air indoors. In the process, the anode high-voltage generating electrode wire loads anode high voltage, air led into the device by the fan is sterilized, virus-killed and deinsectized (killed and carbonized), the cathode dust collecting substrate loads cathode high voltage, and dehumidification and adsorption of micro-dust particles are carried out based on the waterproof breathable nanofiber membrane until the fiber membrane is induced to lose efficacy.

Generally, after a certain period of use, the fiber membrane fails along with the overload of the adsorbed dust particles or the wind erosion of pores, and the fiber membrane needs to be replaced by a new one. And the utility model discloses the device then provides the self-cleaning technical solution who need not manual intervention and go on: in the stage, the sensor module detects the air flowing through to judge the failure state of the waterproof breathable nanofiber membrane, and signals are fed back to the main control part. The air valve of the main control part is switched to an outdoor channel, the operation of the fan is stopped firstly, the automatic cleaning electric brush is driven to repeatedly clean the negative dust collecting substrate from top to bottom, the invalid waterproof breathable nanofiber membrane falls into the waste membrane collecting box, the fan is started to operate after the controlled operation of the automatic cleaning electric brush is finished, and the negative dust collecting substrate is blown clean. And after the negative electrode dust collecting substrate is purified, the spinning stage of the waterproof breathable nanofiber membrane can be shifted to, a new waterproof breathable nanofiber membrane is formed by spinning, and then sterilization and dust removal are performed again.

To sum up, the detailed description of the embodiment combined with the drawings shows that the technical solution of the fresh air purification of the utility model has substantial characteristics. And the application embodies the advancement: by introducing the electromechanical component for automatically spinning and cleaning the nanofiber membrane into the fresh air purification device, the characteristics of large surface area, strong adsorption capacity and environmental friendliness of the waterproof breathable nanofiber membrane are utilized, the consumable replacement rate is reduced, the use cost is saved, the air outlet effect of the device and the service life of a fan can be effectively kept, and the energy consumption is reduced; meanwhile, the volume of the waste is small and the waste is easy to treat after being used, so that secondary pollution to the environment is avoided.
