Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, further describes to the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With new, it is not used to limit the utility model.
Fig. 1 to Fig. 3 is referred to, the utility model is a kind of wind speed air volume sampling device applied in kitchen appliance, if
It is placed on kitchen appliance, it includes：Governor circuit on wind pressure sensor 100, the wind pressure sensor 100 and kitchen appliance
It is connected by electric signal between 200；The governor circuit 200 enters for collecting differential pressure signal to positive and negative thief hatch
Row analysis simultaneously will be provided with governor circuit in the data is activation after analysis to electrical equipment main body；
Malleation chamber 101 and negative pressure cavity 102, the malleation chamber 101 and negative pressure cavity 102 are provided with the wind pressure sensor 100
On be respectively equipped with malleation mouth 103 and negative pressure mouth 104；And connected by wireway 112 respectively on malleation mouth 103 and negative pressure mouth 104
There are positive sampling needle 105, negative sampling needle 106；And the positive and negative sampling needle 105,106 may be contained within the air exhaust passage of kitchen appliance；
The positive sampling needle 105 is provided with positive thief hatch 107, and the positive thief hatch 107 is towards the air intake direction in the air exhaust passage, institute
State negative sampling needle 106 and be provided with negative thief hatch 108, the direction of the negative thief hatch 108 is different from the direction of positive thief hatch 107.
The positive thief hatch 107 is angle, and it is adopted just to the set-up mode of airflow direction.
Further, the negative thief hatch 108 is toward the air-out direction in air exhaust passage.The negative thief hatch 108 of institute is angle,
It adopts the set-up mode back to airflow direction.
Further, the negative thief hatch 108 is toward the madial wall in air exhaust passage.Institute's thief hatch is flat mouth, and it is adopted
Set-up mode of the side to airflow direction.Because this negative thief hatch 108 is toward the madial wall in air exhaust passage, it can effectively prevent
The blocking of negative thief hatch 108 is only caused because of the drippage of top greasy dirt.
Further, flexible partition 109 is provided between the malleation chamber 101 and negative pressure cavity 102, the flexible partition 109
Lower section is provided with for the bracing frame of the support flexible partition 109, and magnet ring 110, support frame as described above bottom are fixed with support frame as described above
