Abstract
A dust-fullness electronic display structure of a dust collector is characterized by comprising a circuit board, a gas-guide tube, a motor and a dust collecting barrel. An air inlet of the motor is communicated with an air inlet of the dust collecting barrel. The circuit board is provided with a pressure sensor and an indicator light which shines when the pressure sensor is under the action of the air pressure. An air collecting point at an air inlet end of the gas-guide tube is arranged at the air inlet of the motor, and an air outlet end of the gas-guide tube is connected with the pressure sensor. Compared with the prior art, the dust-fullness electronic display structure has the advantage that pressure change is guided by the gas-guide tube to the pressure sensor so as to trigger the indicator light to prompt, therefore the pressure sensor suffers less micro-motion interference from impurities in the air and the air pressure and the trigger is more accurate and stable.
Description
Technical field
The utility model relates to a kind of dust catcher accessory structure, relates in particular to a kind of dust-full electronics display structure of dust catcher.
Background technology
The dust-full structure of existing dust catcher has employing pressure switch mechanical structure, as the patent No. is Chinese utility model patent " dust catcher the pressure switch " (Granted publication number: CN2276663Y) of ZL96241887.0, also have and adopt pressure inductor, as the patent No. be ZL200420098123.5 Chinese utility model patent " dust-full alarm formula bag dust filter " (Granted publication number: CN2744395Y) and the patent No. be ZL92237011.7 Chinese utility model patent " the dust-full automatic audio alerting unit of dust catcher " (Granted publication number: CN2744395Y).
Analyze above-mentioned open source literature, the type of alarm of applying pressure sensor is quick on the draw than mechanical type, and installing space is less, good reproducibility, be the development trend in present technique field, but that the pressure sensor of above-mentioned document directly is used for sensed pressure as the gas production point is poor, gas neither one transition structure is designed, be easy to be subjected to the fine motion of the invasion of impurity in the air or air pressure and sensing error occurs, influence result of use.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of pressure sensor to use the dust-full electronics display structure of stable and accurate dust catcher at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of dust-full electronics display structure of dust catcher, it is characterized in that comprising wiring board, wireway, motor and control of dust tube, the air inlet of aforementioned motor communicates with the air inlet of aforementioned control of dust tube, aforesaid wiring board is provided with pressure sensor and this pressure sensor is subjected to can show shinny indicator lamp behind the gas pressure, the gas production point of aforementioned wireway inlet end is located at the air inlet of described motor, and the outlet side of aforementioned wireway then is connected with aforesaid pressure sensor.
The air inlet of described motor is provided with an extra large handkerchief filter assemblies, and this sea handkerchief filter assemblies is positioned at described control of dust tube, and this design guarantees that extra large handkerchief obstruction can cause that also indicator lamp is shinny.
Also be provided with the float that can float behind the water in the described extra large handkerchief filter assemblies.This design guarantees that control of dust tube water can cause that completely also indicator lamp is shinny.
Compared with prior art, advantage of the present utility model is: utilize wireway that air pressure change is directed on the pressure sensor and remind to trigger indicator lamp, making pressure sensor disturbed by the fine motion of impurity and air pressure in the air reduces, trigger more stable, help guaranteeing permanently effective use, the preferred arrangements of gas production point, accurately the perception air-flow changes through the pressure in extra large handkerchief filter assemblies and the control of dust tube; In addition, the pressure that water completely causes changes equally also and can be guaranteed the normal use of dust catcher by the pressure sensor perception.
Description of drawings

Fig. 2 is a circuit board structure for amplifying schematic diagram among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, dust catcher in the present embodiment comprises body 1, dust-full electronics display structure, control of dust tube 4, motor 9 and Hai Pa 5, dust-full electronics display structure comprises and is wiring board 2 and wireway, wireway comprises first tracheae 31, second tracheae 33 and the transition joint 32 that is used to be connected first tracheae 31 and second tracheae 33, motor 9 communicates with the air inlet of control of dust tube 4, as shown in Figure 2, wiring board 2 is provided with pressure sensor 7 and indicator lamp 8, pressure sensor 7 is subjected to can trigger behind the gas pressure indicator lamp 8 and shows shinny, the gas production point 34 of second tracheae, 33 inlet ends is located at motor 9 air inlets, the air inlet that sea handkerchief filter assemblies 5 is located at motor 9 is positioned at control of dust tube 4, the outlet side of first tracheae 31 pressure sensor 7 then connects, and also is provided with the float 6 that can float behind the water in the extra large handkerchief filter assemblies 5.
When extra large handkerchief filter assemblies 5 the inside dusts blocked, air pressure inside caused variation, and it is shinny that pressure sensor 7 triggers indicator lamp 8, reminds the user can clean extra large handkerchief filter assemblies 5; Dust impurity in control of dust tube 4 more for a long time, air pressure inside causes variation, it is shinny that pressure sensor 7 also triggers indicator lamp 8, reminds the user can topple over control of dust tube 4; In addition, the water in extra large handkerchief filter assemblies 5 causes float 6 come-ups more for a long time, and air pressure inside causes variation, and it is shinny that pressure sensor 7 also triggers indicator lamp 8, reminds user's water to expire.
