Description

A kind of interior decoration air purifier and indoor purifying method
Technical field
The present invention relates to the technical fields of interior decoration equipment, more specifically, it relates to which a kind of interior decoration air is net Change device and indoor purifying method.
Background technique
Indoor nocuousness gas mainly has formaldehyde, benzene, dimethylbenzene, TVOC (total volatile organic compounds) etc., and formaldehyde is by generation Boundary's health organization is confirmed as carcinogenic and teratogen, and finishing material and furniture are the main sources for causing formaldehyde pollution.Therefore, newly After family's finishing completion, it is quite important to moving at home to eliminate formaldehyde.
In the prior art, Authorization Notice No. is a Chinese patent document of CN205919435U, discloses one kind and is used for Indoor air cleaner after finishing, including fuselage, the fuselage bottom is equipped with wheel, and the fuselage is connected with power supply and inserts Head, and fuselage two sides are separately installed with air intake window and outlet window.
But this clarifier is as common clarifier, be need it is artificial clarifier is moved to it is right in house Corresponding room in the position or house answered, even can the same house, also have the different place of concentration of formaldehyde, And clarifier can be only positioned a certain fixed position in house, cause to purify required time increase, purification efficiency reduces.
Summary of the invention
In view of the deficienciess of the prior art, the invention reside in provide a kind of interior decoration air purifier and indoor net Change method has the effect of improving purification efficiency.
To achieve the above object, the present invention provides the following technical scheme that a kind of interior decoration air purifier, includes To the ontology that air is purified, ontology lower end is equipped with the mobile device for moving ontology in the horizontal direction, described Ontology is equipped with multiple detection devices for detecting indoor formaldehyde concentration and exporting detection signal, and multiple detection devices are along horizontal Direction is simultaneously arranged towards all directions;It further include thering is the detection signal for exporting multiple detection devices to be compared and select The control centre in the maximum direction of concentration, the control centre connect with mobile device and drive mobile device maximum to concentration Direction is mobile.
By using above-mentioned technical proposal, ontology detects the gas to come in multiple directions, and by multiple directions Air in concentration of formaldehyde detected, in the concentration of formaldehyde highest for judging which direction, ontology passes through mobile device Move to the device, realizes the purpose that ontology is found concentration of formaldehyde highest and automatically moved, improve purification efficiency, and Ontology is moved without personnel, facilitates operation.
The present invention is further arranged to: there are four the detection device settings and the formaldehyde of four different directions of detection is dense Degree, four detection devices are rectangular around being arranged in the horizontal direction.
By using above-mentioned technical proposal, the rectangular setting of four direction, four detection devices are to four different sides It is detected to air, four direction just can be for ontology all around, and equal to the direction in four orientation, total is more Adduction reason, it should be mentioned that, ontology later can be by giving off clean gas by air cleaning upwards.
The present invention is further arranged to: placing groove there are four opening on the ontology, four placing grooves and four detections Device is arranged in a one-to-one correspondence, and the ventilating board for protecting detection device is slidably equipped on the ontology.
By using above-mentioned technical proposal, placing groove plays the role of stable detection device, while ventilating board plays protection The effect of detection device.
The present invention is further arranged to: being fixed with multiple protection branch being arranged along the vertical direction on the leaning to one side of the ontology Frame.
By using above-mentioned technical proposal, since ontology can move freely in house, protective cradle plays protection ontology Effect.
The present invention is further arranged to: the protective cradle is arranged in a ring, and is arranged on the outer ring of the protective cradle There is rubber layer.
By using above-mentioned technical proposal, convenient for ontology the movement on position occurs when hitting for annular setting, Play the role of letting out power, to play protection ontology.Rubber layer has the function of buffering, protects to protective cradle Shield, further strengthens the protection to ontology, so that ontology is more stable when moving.
The present invention is further arranged to: flexible net arranged in a crossed manner between two adjacent protective cradles.
By using above-mentioned technical proposal, elastic network(s) has elastic force, since ontology needs to detect the gas in all directions The concentration of middle formaldehyde, so the surrounding of ontology cannot have too many entity to prevent the circulation of air, therefore protective cradle Setting in the vertical direction cannot be blocked up, can not be excessive, at this time arranged in a crossed manner between two adjacent protective cradles Flexible net plays the role of protecting ontology, prevents some articles from passing through between two brackets, and stretch cord has bullet Property, it is not easily broken, there is certain deformability, also act as the effect of buffering, reinforce the protection to ontology.
The present invention is further arranged to: the mobile device includes to be rotatablely connected rotating member with ontology and drive rotation The servo motor of part rotation;The rotating member is equipped with rotating wheel and for driving rotating wheel rotational drive motor.
By using above-mentioned technical proposal, control centre can control the rotation side of rotating wheel by controlling servo motor To the moving direction of ontology being adjusted to towards the highest direction of concentration of formaldehyde to control the moving direction of ontology.Control Center passes through control driving motor again and rotating wheel is rotated, and realizes the movement of ontology.
The present invention is further arranged to: the rotating member is equipped with the protective cover for protecting rotating wheel.
By using above-mentioned technical proposal, the setting of protective cover is played the role of protecting rotating wheel, prevents rotating wheel from turning Some a lower height of objects are directly hit in dynamic process, so that ontology is more stable in moving process.
To achieve the above object, the present invention provides the following technical scheme that a kind of indoor purifying method, includes following step It is rapid: S1, point and multiple and different directions of datum mark to be carried out with the detections of concentration of formaldehyde on the basis of select a position in house; S2, the concentration of formaldehyde that each different directions detect is subjected to real time contrast and selects the highest direction of concentration;S3, by datum mark It is mobile towards the highest direction of concentration selected.
By using above-mentioned technical proposal, a position on the basis of point is selected in house, which carries out air net Change, then more side directions of the datum mark are detected, then judge the highest direction of concentration, finally controls datum mark towards dense It is mobile to spend highest direction, has the effect of improving purification efficiency.
In conclusion the invention has the following advantages:
1. air of the ontology in the house side Nei Duisi is judged in real time, and according to judging result to concentration of formaldehyde highestly Fang Yidong is improved to house purifying efficiency;
2. ventilating board, protective cradle, rubber layer, elastic network(s) and protective cover play the role of protecting ontology, to play Protect the effect of detection device;
3. the method for indoor purifying has the effect of constantly looking for the higher position of concentration in house and be purified, improve Purification efficiency.
