The specific embodiment
Core of the present utility model is to provide a kind of air purifier, the accuracy detecting to improve its dust sensor.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to shown in Fig. 1-Fig. 3, the utility model embodiment discloses a kind of air purifier, comprises the air intake passage 1 with air inlet, and it also comprises: the dust sensing device 4 that is arranged on the wallboard outside, air channel of air intake passage 1; Be opened on the air channel wallboard of air intake passage 1, for being communicated with the ventilative window 2 of dust sensing device 4 and air intake passage 1; Be arranged on the wallboard inner side, air channel of air intake passage 1, for the abat-vent of window 2 that the air guide in air intake passage 1 is breathed freely.
When reality is used, after air purifier is opened, outside air enters air intake passage 1 by air inlet, under the effect of keeping out the wind of abat-vent, part flowing gas in air intake passage 1 is caused and stopped, make this part air moving to refluxing, and under the mobile impact of integrated air, make return air pass to dust sensing device 4 by the ventilative window 2 being arranged on the wallboard of air channel, so that air is detected.By above-mentioned setting, can make the gas in air purifier quick, and a large amount of pass through ventilative window 2 and enter dust sensing device 4, thereby improve the accuracy of dust sensing device 4, avoid occurring air purifier maloperation or delay-action problem.
In preferred embodiment, dust sensing device 4, ventilative window 2 and abat-vent are all arranged on to the air inlet end of air intake passage 1.Because the air velocity of the air inlet end of air intake passage 1 is very fast, and more can embody the quality of outside air, therefore, by above-mentioned parts being arranged on to air inlet end, can further improve by ventilative window 2 and enter the flow of dust sensing device 4, and can improve the accuracy that dust sensing device 4 detects.
In specific embodiment, this dust sensing device 4 is dust sensor, it will be appreciated by persons skilled in the art that in actual production and can different dust sensing devices 4 need to be set according to different, to realize different functions.
Further, on dust sensing device 2, offer the detection mouth 41 relative with ventilative window 2.In testing process, by abat-vent by the ventilative window 2 of the air guide in air intake passage 1, and by ventilative window 2 by the detection mouth 41 of air guide dust sensing device 4.Particularly, dust sensor is fixed on the air channel wallboard of air intake passage 1, and guarantees to detect mouthful 41 and connections relative with ventilative window 2.For detect mouthfuls 41 and shape and the large I of ventilative window 2 set arbitrarily, preferably, detect the size that mouthfuls 41 size is set to be less than ventilative window 2.
A kind of structure of abat-vent is provided in one embodiment, particularly, above-mentioned abat-vent is the deep bead being arranged on the air channel wallboard of air intake passage 1, and deep bead is arranged perpendicular to air channel wallboard, on the wallboard of the air channel of air intake passage 1, increases the deep bead of the window 2 of air guide can being breathed freely.In practice, deep bead arranges along ventilative window 2, and the direction that guarantees circulation of air in air intake passage 1 has opening near one end of air inlet, so that air can reach ventilative window 2.
Particularly, above-mentioned deep bead comprises: the first deep bead and the second deep bead.Wherein, the first deep bead be positioned at ventilative window 2 along air intake passage 1 axially and away from a side of air inlet, the setting by the first deep bead can guarantee that the air in air intake passage 1 can and be stopped and reflux by the first deep bead through ventilative window 2; The second deep bead is positioned at the side radially along air intake passage 1 of ventilative window 2, by the setting of the second deep bead, can further lead to the air refluxing, and prevents from flowing away from side, thereby has further increased by the flow of the air of ventilative window 2.
In practice, deep bead can be communicated with the top end face of air intake passage 1, when along radially the arranging of air intake passage 1, can be only in a side of the top end face away from air intake passage 1, the second deep bead be set, and a side of the top end face of close air intake passage 1 does not arrange, thereby realize, be communicated with.
A kind of structure of abat-vent is also provided in another specific embodiment, it particularly, this abat-vent is the groove being opened on air intake passage 1, in the present embodiment, is by offer groove on air intake passage 1, the air in air intake passage 1 is led by cell wall.This groove comprise the diapire 32 that keeps out the wind away from air inlet, with vertical keep out the wind sidewall 33 and the diapire 31 relative with dust sensing device 4 being connected of the diapire 32 that keeps out the wind, wherein, ventilative window 2 is arranged on diapire 31.Above-mentioned setting can be regarded as, and at air intake passage 1, near a side of air inlet, has offered a L-type groove, so that the air entering from air inlet can be kept out the wind, diapire 32 stops, thereby enters ventilative window 2 on diapire 31.Height for the diapire 32 that keeps out the wind of groove can need to be set according to difference, at this, is not specifically limited.
The abat-vent of the form of grooves providing in the present embodiment is identical with the above-mentioned mode core that deep bead is set, and its similar place can use for reference mutually.
In practice, groove can be communicated with the top end face of air intake passage 1.While being convenient to groove and air intake passage integrated injection molding, groove and air intake passage, from same direction depanning, are simplified mould, are beneficial to depanning.
On the basis of technique scheme, the window 2 of breathing freely is set to square orifice, it will be appreciated by persons skilled in the art that ventilative window for other shapes is also in protection domain.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
