The utility model content

The purpose of this utility model is, provide a kind of tool to block the air filter machine of deixis, be to include one to go out, the casing of air intake vent, the side plate of its adjacent inlet and outlet in casing surface is provided with a window, one is positioned at, filter between air intake vent, one is positioned at the exhaust blower between this filter and air outlet, it has a cover body that exhaust blower is coated, this cover body has two air inlets and an exhaust outlet that communicates with air inlet, and exhaust outlet communicates with the air outlet of casing, this gas outlet and this air outlet are provided with an airflow sensing apparatus, this airflow sensing apparatus has a pedestal, articulate a body of rod on this pedestal, the other end of this a body of rod and indicator board is fixed joins, this indicator board is located in the casing corresponding with the window of casing, and its indicator board plate face is provided with different marks, and its body of rod is along its axial binding one blinker.

Tool of the present utility model blocks the air filter machine of deixis; its air filter machine is when start; when then the air-flow of exhaust blower was through exhaust outlet when if filter did not block as yet; being enough to order about blinker is moved to and the airflow direction parallel position; blinker drives the mark rotation that the body of rod makes the color block on the indicator board simultaneously; the mark of seeing the color block of its casing window can be understood the situation of its internal blocking; window has a transparent coversheet to cover outward; can avoid between indicator board and the window crack to have that dust is dirty to be adhered to; indicator board is installed in can protect indicator board not to be subjected to the outer foreign object strike of casing on the interior body of rod of casing; and its indicator board does not join with casing inner wall; rocking when it can avoid mobile makes the continuous body of rod produce crooked infringement.

Feature of the present utility model and attainable expection effect thereof are presented below:

1. the utility model judges that according to color on the indicator board in the window filter blocks situation, can filter be taken out cleaning when taking place in blocking situation, avoids the clear damage with exhaust blower of filter effect.

2. the utility model is located at machine shell inside with indicator board, and it can avoid indicator board to be subjected to external force collision to produce damage.

3. the utility model covers window surface and can avoid dust impurity to be attached to crack between indicating piece and the window with backplate.

4. as mark, look by in bright gay color promptly distinguishing easily at a distance with color for indicator board of the present utility model, so the user is very convenient in the use as long as the color of watch window can be understood the degree that air filter machine blocks.
