And if the test is not passed, the total replacement cost is too high.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the smoke purifier with the filter element saturation self-checking function can automatically detect whether a plurality of filter elements in the smoke purifier are saturated or not in real time, saves time and labor, and does not need to stop running because of detecting the saturation state of the filter elements.
In order to solve the technical problem, the technical scheme of the utility model is that:
smoke purifier with filter element saturation self-checking function, including fan and filter unit, filter unit includes that one, two or a plurality of filter element cross, the entrance point of fan with filter unit's the end of giving vent to anger is connected, every be connected with a pressure differential sensor between filter element's the inlet end and the end of giving vent to anger, the display element is connected to the pressure differential sensor electricity, display element electricity connects the alarm element.
Preferably, the differential pressure sensor is a piezoresistive pressure sensitive element.
Preferably, the differential pressure sensor is an XGZP190 pressure sensor.
Preferably, the alarm element is an alarm signal lamp and/or a buzzer.
Preferably, the display element is a display screen, a touch screen or a computer, a pressure gauge.
Preferably, a plurality of the filter elements are connected in series.
Preferably, the fan is electrically connected with a fan controller.
After the technical scheme is adopted, the beneficial effects of the utility model are that:
the utility model discloses a smoke purifier with filter core saturation self-checking function, every filter core's inlet end and give vent to anger and be connected with a pressure differential sensor between the end, the display element is connected to the pressure differential sensor electricity, and the alarm element is connected to the display element electricity. When one of the filter elements is saturated, the pressure difference sensor which is correspondingly connected with the filter element detects that the pressure difference between the air inlet end and the air outlet end of the filter element is too high and is higher than a saturation value, the display element visually displays the pressure difference and transmits the pressure difference to the alarm element to give an alarm, so that a worker can timely know the saturation condition of the filter element to replace the corresponding saturated filter element in time, and the smoke purifier starts from the working principle of the smoke purifier and combines the use characteristics of the filter element and a fan control system. A plurality of differential pressure sensors are employed to monitor the usage status of each filter element. Can judge which layer of filter element reaches saturation according to the air pressure and needs to be changed, reach the purpose of using clearly, practicing thrift filter element replacement cost. The smoke purifier with the function of self-checking the saturation of the filter element can automatically detect whether a plurality of filter elements in the smoke purifier are saturated or not in real time, saves time and labor, and does not need to stop running because of detecting the saturation state of the filter elements.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the smoke purifier with a filter saturation self-checking function of the present embodiment includes a fan 1 and a filter unit 3, where the filter unit 3 includes one, two, or more filter elements 31, and the filter elements 31 are connected in series. The smoke to be purified is pumped into the multistage filter element 31 by the fan 1, and is purified by multistage filtration. The fan 1 is electrically connected to a fan controller 2. The operating speed of the fan 1 can be controlled by the fan controller 2. The outlet end of the fan 1 is connected with the air inlet end of the filtering unit 3, a pressure difference sensor 4 is connected between the air inlet end and the air outlet end of each filtering core 31, the pressure difference sensor 4 is electrically connected with a display element 5, and the display element 5 is electrically connected with an alarm element 6.
The differential pressure sensor 4 may be a piezoresistive pressure sensitive element, such as a XGZP190 pressure sensor.
The alarm element 6 may select an alarm signal lamp and/or a buzzer. The display element 5 can be a display screen, a touch screen, a computer or a pressure gauge, and can be purchased in the market, and is not described in detail herein.
The utility model discloses a smoke purifier with filter core saturation self-checking function at first selects traditional experiment to confirm the filter core 31 that has saturated, at the inlet end of filter core 31 and give vent to anger and connect differential pressure sensor 4 between the end, detects out the air pressure difference between the inlet end of saturated filter core 31 and the end of giving vent to anger, as the saturated air pressure difference value of filter core 31.
