Abstract
It the utility model is related to VMC technical field, more particularly to a kind of screen replacing decoration of wall-mounted new blower fan.The device includes casing and high efficiency particulate air, outdoor PM2.5 sensors are installed close to the position of fresh air air inlet in casing, indoor PM2.5 sensors are installed close to the position of waste air air inlet, outdoor PM2.5 sensors and indoor PM2.5 sensors are connected with alarm set by controller；The track of the high efficiency particulate air both sides is provided with sealing strip.The device is reasonable in design, and the METHOD FOR CONTINUOUS DETERMINATION to PM2.5 concentration can be achieved, and when PM2.5 contents are higher than setting value, controller sends signal to alarm set, and alarm set sends prompting, reminds people to change filter screen.
Description
（One）Technical field
It the utility model is related to VMC technical field, more particularly to a kind of screen replacing device of wall-mounted new blower fan.
（Two）Background technology
From outdoor introducing fresh air when New-air purifying system works, after filter screen filtration in supply chamber, room is improved with this
Interior air quality.Gradually increase with the usage time of filter screen, the pollutant accumulated on filter screen is more, can cause filter screen to air
Filtration, purification effect be gradually deteriorated, filter screen just loses normal filtration, purification function, it is necessary to change.It is usually used in prompting filter at present
The method that net is changed is the program of a built-in accumulative air purifier working time in new blower fan, when air purifier adds up
When working time reaches, suggesting that needs to change filter screen.But the air quality of various regions is different in actual conditions, good in air quality
Regional filter screen the longer point of service life, air quality difference regional filter screen the shorter point of service life, so if more
Waste screen pack is changed early, has changed evening and cause filter effect to be deteriorated, influence the output effect of new blower fan.
（Three）Utility model content
The utility model is in order to make up the deficiencies in the prior art, there is provided and it is a kind of reasonable in design, there is screen replacing to remind
The screen replacing device of the wall-mounted new blower fan of function.
The utility model is achieved by the following technical solution：A kind of screen replacing device of wall-mounted new blower fan, bag
Include casing and high efficiency particulate air, it is characterised in that：The cabinet rear panel is provided with fresh air air inlet, distinguishes on enclosure side panel
Provided with fresh air air outlet and waste air air inlet；Outdoor PM2.5 sensors are installed close to the position of fresh air air inlet in casing, leaned on
The position of nearly waste air air inlet is provided with indoor PM2.5 sensors, and outdoor PM2.5 sensors and indoor PM2.5 sensors pass through
Controller is connected with alarm set；The high efficiency particulate air is arranged close to the position of fresh air air outlet, high efficiency particulate air both sides
Track be provided with sealing strip.
Further, the alarm set is the one or more in indicator lamp and attention device.
Further, the sealing strip is wool top.
The beneficial effects of the utility model are：The device is reasonable in design, and the METHOD FOR CONTINUOUS DETERMINATION to PM2.5 concentration can be achieved, when
When the cumulative total values of PM2.5 are higher than setting value, controller sends signal to alarm set, and alarm set sends prompting, reminds people
Filter screen is changed, can also so as to avoid filter screen from being replaced wasting problem when service life is not use up
Avoid filter screen be not replaced after reaching service life cause filter effect to be deteriorated the problem of；The setting of sealing strip enhances filter screen
Sealing between track, and during replacing filter screen, filter screen is easier to extract out, is convenient for changing.
（Four）Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the schematic diagram of the utility model sealing strip.
Accompanying drawing 3 is operation principle schematic diagram of the present utility model.
In figure, 1, casing, 2, high efficiency particulate air, 3, fresh air air inlet, 4, fresh air air outlet, 5, waste air air inlet, 6, room
Outer PM2.5 sensors, 7, indoor PM2.5 sensors, 8, alarm set, 9, sealing strip.
（Five）Embodiment
The utility model is described in further detail with reference to specific embodiment.
As shown in Figure 1-Figure 3, the embodiment includes casing 1 and high efficiency particulate air 2, and the rear board of casing 1 is provided with new
Wind air inlet 3, fresh air air outlet 4 and waste air air inlet 5 are respectively equipped with the side panel of casing 1；Close to fresh air air inlet in casing 1
3 position is provided with outdoor PM2.5 sensors 6, and indoor PM2.5 sensors 7, room are provided with close to the position of waste air air inlet 5
Outer PM2.5 sensors 6 and indoor PM2.5 sensors 7 are connected with alarm set 8 by controller；The high efficiency particulate air 2 is installed
Sealing strip 9 is being provided with close to the position of fresh air air outlet 4, the track of the both sides of high efficiency particulate air 2.
The alarm set 8 is the one or more in indicator lamp and attention device.
The sealing strip 9 is wool top.
Outdoor PM2.5 sensors 6 are measured to the PM2.5 concentration in outdoor fresh air, and indoor PM2.5 sensors 7 are to entering
The PM2.5 concentration for entering the indoor waste air of casing 1 is measured, and result is fed back into controller, and controller is real by arithmetic unit
Now calculate, record and control, the data of collection in every 15 minutes, and added up in PM2.5 historical datas, work as PM2.5
When cumulative total value is higher than setting value, controller sends signal to alarm set 8, and alarm set 8 sends prompting, reminds people to height
Effect screen pack 2 is changed；The setting of sealing strip 9 enhances the sealing between filter screen and track, and during replacing filter screen, filter
Net is easier to extract out, is convenient for changing.
One kind of embodiment described above, simply the utility model more preferably embodiment, the skill of this area
The usual variations and alternatives that art personnel are carried out in the range of technical solutions of the utility model should all be included in guarantor of the present utility model
In the range of shield.
