In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example one
Referring to fig. 1 to 6, the present embodiment provides an air purifier, including:
an air purifier, comprising:
an air cleaner body 10;
an air inlet 11; and
and the humidity sensor 20 is arranged inside the air purifier and close to the air inlet 11.
Preferably, be provided with in the air purifier electric purification module 30, when the pollutant in the air passes through the wind channel and gets into electric purification module, move to the negative electrode by the positive electrode under the drive of fan, the pollutant receives positive polarity strong electric field to influence by the field and charged, become the particle of positive charge, and in the electric field, receive coulomb force according to the electric polarity and influence the direction of motion and deflect, strike negative electrode plate dust collecting plate promptly, the particulate matter that is positive electric and the polar plate of negative electric carry out the electric bonding, produce adhesive force, make the particulate matter adsorbed, thereby realized the purification to the pollutant in the air.
Specifically, the electrical purification module 30 includes a generator unit and a collector unit, and the generator unit mainly discharges air to make particles in the air attach electric charges; correspondingly, the collector unit is used for capturing the charged particles. The generator unit comprises at least one corona wire, which acts as a discharge to air, and in some embodiments is preferably a tungsten wire. When a dc voltage of a certain polarity (positive and negative) is applied to the corona wire, the corona wire can discharge the surrounding air and generate plasma of the corresponding polarity, thereby charging the particles around the electric field. The collector unit includes at least one electrode plate, and the electrode plate of the collector unit may be applied with a voltage of opposite polarity to the corona wire. The trapping of particulate matter is achieved when the charged particulate matter is in close proximity to the electrode plates, which in some embodiments are preferably aluminum plates.
Preferably, a fan is further disposed in the air purifier, and the fan rotates to attract air to enter from the air inlet 11 of the air purifier, and in the air flowing process, the air passes through the electrical purification module 30, specifically, the air moves from the positive electrode to the negative electrode under the driving of the fan. Correspondingly, the air purifier is also provided with an air outlet. In this embodiment, it is preferable that the air inlet 11 is disposed at the bottom of the air purifier, and the air outlet is disposed at the top of the air purifier or near the top.
Although the electric purification module 30 that sets up in the air purifier can play better absorption of disinfecting, nevertheless has certain risk equally in the use, when humidity in the air is too big, after the temperature value reached certain numerical value, air purifier electric purification module was because of moisture height in the dust appears electric conductivity can take place to strike sparks phenomenon with the positive pole, has the potential safety hazard. Therefore, it is necessary to correspondingly adjust the discharge voltage of the purification module according to the humidity value in the air, and even to turn off the electrical purification module.
Preferably, a humidity sensor 20 is disposed inside the air purifier and near the air inlet 11, and the humidity sensor 20 is configured to detect the humidity of the air. This embodiment is through adding humidity transducer in air purifier for the humidity in the detection air, and prevent the protection of striking sparks according to the humidity value. When the humidity value in the air is detected to be too large, the discharging voltage of the electric purification module is adjusted until the electric purification module is closed, so that the anti-ignition protection is realized.

As the humidity in the air changes, the insulation effect of the air as an insulation layer changes along with the change of the humidity in the air, the insulation effect is worse when the humidity is higher, and the conductive effect is better; the smaller the humidity is, the better the insulation effect is, and the poorer the conductive effect is; therefore, the conduction voltage between the generator unit and the collector unit of the electrical purification module 30 will change, and the higher the humidity is, the more easily the conduction is, and the lower the humidity is, the less easily the conduction is, under the condition that the discharge voltage of the electrical purification module 30 is not changed.
Therefore, in order to avoid sparking, the discharge voltage is adaptively adjusted based on the air humidity detected by the humidity sensor 20, so as to avoid the occurrence of sparking due to conduction between the generator unit and the collector unit.
However, after the discharge voltage of the electrical purification module 30 is lowered, the efficiency of purifying air is also lowered accordingly, and in order to maintain the purification effect, the air volume needs to be reduced accordingly, so that the volume of air entering the air purifier per unit time is reduced, and the purification effect is ensured.
The air purifier that this embodiment provided is through being close to in its inside 11 positions of air intake are provided with humidity transducer 20 for detect the humidity of air to adjust the discharge voltage of electric purification module according to the humidity value, thereby realize preventing the protection of striking sparks, solved because humidity is too big in the air, the problem of air purifier electric purification module emergence potential safety hazard of striking sparks, improve air purifier's security, guarantee safe in utilization.
As a variation, the humidity sensor 20 may also be a temperature and humidity sensor, and the temperature and humidity sensor is used to detect the temperature and humidity of the air.

The support frame assembly 12 and the base 40 are abutted against each other at the central position and are separated from each other at the edge area, so that the air inlet 11 is formed at the gap between the support frame assembly 12 and the base 40. Support frame subassembly 12 sets up air purifier body 10's bottom, through with humidity transducer 20 install in on the support frame subassembly 12 for humidity transducer 20 is close to air intake 11 position more, thereby makes humidity that humidity transducer 20 detected accord with the true humidity in the air more, makes error control within 5%.
Specifically, the method further comprises the following steps: the support frame assembly 12 is formed with a mounting position 13, and the humidity sensor 20 is disposed in a mounting groove 14 of the mounting position 13.
Specifically, the bottom of the mounting position 13 is closed, and the upper part is open, so as to form the mounting groove 14.
Specifically, a buckle 15 is arranged in the mounting position 13, and the buckle 15 is suitable for clamping the humidity sensor 20.

When humidity transducer 20 installs, put into humidity transducer 20 along the guide of direction muscle 16 and press to the end for buckle 15 carries out the joint to humidity transducer 20, thereby dies humidity transducer 20 card in mounting groove 14, in order to reach fixed mounting's purpose.
Specifically, the installation site 13 is disposed on an air guide path of the air purifier. Through setting up installation position 13 air purifier's wind-guiding route for humidity transducer 20 is in the wind-guiding route equally, and does not have the structure around humidity transducer 20 to block, and the air that the air intake came in can the convection current flow, makes the air very fast contact with humidity transducer 20.
Specifically, the bottom surface of the mounting position 13 is a windward surface.
Specifically, the mounting locations 13 are disposed on the cross arm of the support frame assembly 12.
By installing the humidity sensor 20 in the air guiding path of the air cleaner at the upper portion of the air inlet, the sensing surface of the sensor can be sufficiently contacted with the ambient air. Inside back of air purifier is got into from the air intake to moist air, enters into support frame upper portion simultaneously very fast, installs the humidity transducer on the xarm and detects the humidity in the air, sets up humidity transducer 20 at the leeward side, and its detection state is closer to natural environment, avoids detecting the influence of authenticity to humidity transducer 20 under the windward state, makes things convenient for humidity transducer 20's installation simultaneously.

For another example, when the RH is 85%, the difference between the RH and the first threshold is 5%, the discharge voltage may be reduced to 8kv, and the rotation speed of the fan is adjusted to 3500 r/min; when the RH is 90%, the difference value between the RH and the first threshold is 10%, the discharge voltage can be reduced to 6kv, and the rotating speed of the fan is adjusted to 3000 r/min.
For another example, when the RH is 75%, the difference between the RH and the first threshold is 15%, and the difference between the RH and the second threshold is 5%, the optimal operation state may be adjusted according to the current value, so as to reduce power consumption.
