Abstract
A kind of ventilating fan, including cabinet, top surface are provided with air duct, and air duct top surface is provided with air change outlet, and blower is provided in cabinet, and blower is located under air change outlet, it is characterised in that: the baffle of equidistant interval is provided in the air change outlet；The air duct top surface is provided with strainer mounting rack, and strainer mounting rack center is fixed with motor bottom end, and the motor other end is fixedly connected with strainer center；Strainer shape is identical as baffle interval shape size, and motor is able to drive strainer rotation, when strainer is located at the interval location of baffle, can cover the interval of baffle；Air quality monitor is additionally provided on strainer mounting rack, air quality monitor can control the switch of motor.Air quality is detected, is directly largely entered the wind by the interval between baffle in the case where air quality is good, when air quality is bad, is spaced and filters the air between strainer covering baffle；Saving strainer reduces cost using the time.
Description
Technical field
The utility model relates to a kind of ventilating fans.
Background technique
Grease tank is exactly the dedicated well for leaving grease, sundries and the moisture in a large amount of waste water released in life；It utilizes
The specific gravity of suspended matter and water is different and reach water-oil separating in waste water, the purpose that sundries is separated from water；After grease tank is used for a long time
Oil-isolating device in oil separator can adhere to considerable grease, influence oil removal effect, need to clear up it, at present to oil removal
The cleaning of well is long to need to clear up entire grease tank, and cleaning efficiency is low, time-consuming and laborious.
Summary of the invention
To solve the above problems, the utility model provides following scheme:
A kind of ventilating fan, including cabinet, top surface are provided with air duct, and air duct top surface is provided with air change outlet, is provided in cabinet
Ventilating fan, ventilating fan are located under air change outlet, and the baffle of equidistant interval is provided in the air change outlet；The air duct top surface is provided with
Strainer mounting rack, strainer mounting rack center are fixed with motor bottom end, and the motor other end is fixedly connected with strainer center；Strainer shape
Identical as baffle interval shape size, motor is able to drive strainer rotation, when strainer is located at the interval location of baffle, can cover
The interval of lid baffle；Air quality monitor is additionally provided on strainer mounting rack, air quality monitor can control motor
Switch.
Further, the baffle is made of three pieces fan shape baffle, and fan shape baffle inner end is overlapped, equidistant between fan shape baffle
It is separated by.
Further, the motor is stepper motor.
Start ventilating fan, air quality monitor detects air, if air quality is preferable, without being filtered
When, blower starting is directly pumped into air and carries out ventilation work；When air quality is poor, starting stepper motor band electric filter turns
Dynamic, until strainer covers baffle interval, the air being pumped at this time reduces the impurity in air through filter screen filtration.It is big when needing
When amount air inlet, then blower directly carries out air extraction, without filtering the air.It can so select according to the actual situation
It selects and whether needs to carry out air filtration, reduce the use of strainer, save electric energy, reduce use cost.
The utility model has the following beneficial effects:
1. judging whether to filter the air using strainer according to air quality, the use of strainer is reduced, reduces and uses
Cost.
2. structure is simple, easy to use.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
1. cabinet；2. air duct；3. baffle；4. strainer mounting rack；5. strainer；6. stepper motor；7. air quality monitoring
Device.
Specific embodiment
The utility model is described in detail now in conjunction with attached drawing:
Embodiment 1: as shown in Figure 1, a kind of ventilating fan, including cabinet 1, box top are provided with air duct 2,2 top surface of air duct
It is provided with air change outlet, ventilating fan is provided in cabinet 1, ventilating fan is located under air change outlet, and equidistant interval is provided in air change outlet
Baffle 3；Baffle 3 is made of three pieces fan shape baffle, and fan shape baffle inner end is overlapped, and is equidistantly separated by between fan shape baffle.1 top surface of air duct
It is provided with strainer mounting rack 4,4 center of strainer mounting rack is fixed with 6 one end of stepper motor, in 6 other end of stepper motor and strainer 5
The heart is fixedly connected；5 shape of strainer is identical as the interval shape size of baffle 3, and stepper motor 6 is able to drive the rotation of strainer 5, when
When strainer 5 is located at the interval location of baffle 3, the interval of baffle 3 can be covered；Air quality is additionally provided on strainer mounting rack 4
Monitor 7, air quality monitor 7 can control the switch of stepper motor 6.
Start ventilating fan, air quality monitor 7 detects air, if air quality is preferable, without being filtered
When, blower starting is directly pumped into air and carries out ventilation work；When air quality is poor, start stepper motor 6 with 5 turns of electric filter
Dynamic, until strainer 5 covers the interval of baffle 3, the air being pumped at this time is filtered through filter screen 5, reduces the impurity in air.When
When needing largely to enter the wind, then blower directly carries out air extraction, without filtering the air.It so can be according to reality
Situation chooses whether to need to carry out air filtration, reduces the use of strainer 5, saves electric energy, reduces use cost.
