Accompanying drawing explanation
Fig. 1 is the schematic diagram of the air purifier according to the utility model embodiment.
Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to the accompanying drawings describe in detail according to air purifier of the present utility model.
As shown in Figure 1, according to air purifier of the present utility model, comprising: housing 10, blower fan 20, filter element 30 and pressure indicator 40.
Specifically, in housing 10, there is air channel 100.Be understandable that, the both ends open in air channel 100 is all communicated with air.Further, the axis in air channel 100 can be straight line, also can be L shape line or U-shaped line.
Blower fan 20 and filter element 30 interval are arranged in air channel 100.Filter element 30 filter element 30 is not particularly limited to, as long as can play the effect of the suspended particulate substance in filtered air.Preferably, filter element 30 can be selected from any combination of any one or they in non-woven fabrics filter core, active carbon filter core or glass fibre filter core.
Pressure indicator 40 is connected with air channel 100 outside housing 10.
Wherein, pressure indicator 40 comprises: body 401, piston 402 and elastic component 403.
The first end (i.e. the left end of body 401 as shown in Figure 1) of body 401 is communicated with air channel 100 and between blower fan 20 and filter element 30.Second end (i.e. the right-hand member of body 401 as shown in Figure 1) of body 401 is in communication with the outside, that is, be communicated with air.Body 401 is transparent tube body, the periphery wall of described transparent tube body has the scale of the motion track of display piston 401.
Piston 402 is located in body 401 movably.Advantageously, body 401 is transparent tube body, the periphery wall of transparent tube body has the scale of the motion track of display piston 402.
The first end of elastic component 403 is connected with piston 402 and the second end of elastic component 403 is connected with the second end of body 402 often to promote second end of piston 402 away from body 401.Elastic component 403 can be Compress Spring.
According to air purifier of the present utility model operationally, because filter element 30 is when filtered air, certain resistance can be produced to air-flow.Further, along with the service time of air purifier increases, the particles such as the dust of interception on filter element 30 increase, and filter element 30 can increase for the resistance of air-flow.
In air channel 100, when air-flow is blowed to filter element 30 by blower fan 20 by blower fan 20, elastic component 403 is moved by the direction compressing to make piston 402 towards the second end near body 401.Because the first end of body 401 to be communicated with air channel 100 and between blower fan 20 and filter element 30.Second end of body 401 is in communication with the outside.So, when air purifier works, air pressure in air channel 100 between blower fan 20 and filter element 30 is greater than atmospheric pressure, cause the air pressure of the first end of body 401 to be greater than the air pressure of the second end of body 401, so will promote the elastic force that piston 402 overcomes elastic component 403 and move towards the direction of the second end near body 401 in body 401.
In air channel 100, when air-flow is pumped to blower fan 20 by filter element 30 by blower fan 20, elastic component 403 is stretched piston 402 is moved towards the direction of the second end away from body 401.In other words, blower fan 20 now plays and takes out wind action.Because the first end of body 401 to be communicated with air channel 100 and between blower fan 20 and filter element 30.Second end of body 401 is in communication with the outside.In this case, during air purifier work, air pressure in air channel 100 between blower fan 20 and filter element 30 is negative pressure, and filter element 30 is due to the cause of filtered air, this negative pressure can be aggravated further, cause the air pressure of the first end of body 401 to be less than the air pressure of the second end of body 401, so will promote the pulling force that piston 402 overcomes elastic component 403 and move towards the direction of the second end away from body 401 in body 401.
And no matter piston 402 moves towards the direction of the second end near body 401, or piston 402 is towards the direction of the second end away from body 401, the displacement of piston 401 and the actual resistance of filter element 30 all present positive correlation, thus, the actual resistance of filter element 30 can be reflected exactly by the movement of piston 401.
And when air purifier does not work, piston 402 can reset under the effect of elastic component 403 restoring force.Thus, the use habit of user and the impact of environment for use can not be subject to.
When the amount of movement of piston 401 when air purifier works reaches certain numerical value, then show that the resistance of filter element 30 has reached its maximum critical value, user should change filter element 30, to ensure that air purifier can normally work.
According to air purifier of the present utility model, being provided with the pressure indicator for measuring filter element resistance, accurately can reflecting the actual resistance of filter element, structure is simple, and cost is low.
According to an example of the present utility model, described air purifier also comprises outer cover 50.Outer cover 50 is connected with housing 10 spatial accommodation 500 limiting pressure indicator 40.Pressure indicator 40 is contained in spatial accommodation 500.Wherein, outer cover 50 is provided with the observation window 501 of the motion track for observing piston 402.Thus, can protect pressure indicator 40, and make the good looking appearance of air purifier complete machine.
Certainly, replace as one, housing 10 and outer cover 50 can be integratedly.Such as, housing 10 and outer cover 50 form body, limit in body apart from one another by air channel and the spatial accommodation of pressure indicator.For can be observed the amount of movement of piston 402 by the observation window 501 on outer cover 50, judge the service condition of filter element thus.This is understandable to those skilled in the art.
