Abstract
The utility model relates to the field of air filters, in particular to a self-reminding air filter which can remind for maintenance and replacement during use. The time for replacing, cleaning and maintaining the air filter can be more accurately determined through the self-reminding air filter. The self-reminding air filter comprises a shell with an air inlet pipe and an air outlet pipe, a filter core in the shell and an electronic alarm device, wherein the air outlet pipe of the shell is provided with a branch pipe which is communicated with the air outlet pipe; a free end of the branch pipe is provided with a trigger device for triggering the electronic alarm device to be started; the trigger device comprises a membrane for closing the free end of the branch pipe and a bracket which is arranged at the free end side in the branch pipe and is right opposite to the membrane; a fixed contact and a movable contact which are arranged right opposite to each other are fixed on the bracket and the membrane respectively; and the movable contact and the fixed contact are connected in series with a power supply loop of the electronic alarm device. The air filter has a simple and rational structure and a good effect and is convenient to use.
Description
Technical field
The utility model relates to the air-strainer field, specifically be a kind of can in use maintain, change prompting from the reminding type air-strainer.
Background technique
Air-strainer be reciprocating machine (internal-combustion engine, reciprocal compressor etc.) must establish device, in order to remove airborne granulometric impurity, avoid reciprocating machine when work to suck impurity such as containing dust in the air and aggravate the wearing and tearing of part.Comprise the housing that is provided with suction tude and steam outlet pipe, place the filter core in the housing, suction tude is communicated with housing and ambient atmosphere environment, steam outlet pipe is communicated with housing and reciprocating machine, when sucking air in the reciprocating machine work, air enters in the air filter housing via suction tude, behind filter core filtering granulometric impurity, enter reciprocating machine by steam outlet pipe at last; After long-time the use, can gather a large amount of impurity on the filter core, cause the reciprocating machine air inlet not smooth, finally influence the work of reciprocating machine.For example: if the filter core of the used air-strainer of automobile is dirty excessively, during automobile running, its motor meeting air inlet deficiency makes oil inflame incomplete, causes engine operation instability, power decline, fuel consumption to increase.We can say that the quality of air-strainer state is concerning the user mode and the working life of reciprocating machine.
Therefore, for satisfying the job requirement of reciprocating machine, must establish the mode of execution that device-air-strainer is taked periodically replacing or the maintenance of periodicity cleaning always at present to it.For the Vehicular air filter cleaner, usually the suggestion client whenever travels 1.5 ten thousand kilometers and just changes or clean, and the vehicle of work should be no more than 10,000 kilometers and just changes or clean in the rugged environment of being everlasting (desert, building site etc.), generally speaking, above-mentioned data only are theoretical presumed value, obtain according to factors " deduction " such as roughly environment, vehicle performances, as the opportunity that air-strainer is maintained and changes, be inaccurate.
Summary of the invention
The utility model provides a kind of from the reminding type air-strainer for replacing opportunity of determining air-strainer comparatively exactly, cleaning maintenance opportunity.
The utility model is to adopt following technological scheme to realize: from the reminding type air-strainer, comprise the housing that is provided with suction tude and steam outlet pipe, place the filter core in the housing, also comprise the electronic type warning device, and the steam outlet pipe of housing is provided with the arm that is communicated with steam outlet pipe, the free end of arm is provided with the flip flop equipment that is used to trigger the electronic type alarm activation, described flip flop equipment comprises the free-ended diaphragm of sealing arm and is arranged at free end side in the arm, with diaphragm over against support, be fixed with respectively on support and the diaphragm over against the fixed contact that is provided with, moving contact, and moving, fixed contact is series in the current supply circuit of electronic type warning device.Described electronic type warning device can be directly by buying, for example on the market: tutorial light early warning type, buzzer early warning type etc.
Prompting principle of the present utility model is: gather the increase of impurity level along with air cleaner cartridge, intake resistance also progressively increases, when sucking air in the reciprocating machine work, can form negative pressure in the steam outlet pipe of air-strainer, negative pressure can be impelled suction in the free-ended diaphragm of arm, when negative pressure is enough big when having reached the degree of the work of influence (air cleaner cartridge gather impurity level), moving, the fixed contact contact, make the current supply circuit conducting of electronic type warning device, the electronic type warning device gets electric alarm, reminds the car owner to clean air-strainer and maintains or changed.
The utility model is simple and reasonable for structure, and is easy to use, effective, can determine replacing opportunity, cleaning maintenance opportunity of air-strainer comparatively exactly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: the 1-suction tude; The 2-steam outlet pipe; The 3-housing; The 4-filter core; 5-electronic type warning device; The 6-arm; The 7-diaphragm; The 8-support; The 9-fixed contact; The 10-moving contact.
Embodiment
As shown in Figure 1, from the reminding type air-strainer, comprise the housing 3 that is provided with suction tude 1 and steam outlet pipe 2, place the filter core 4 in the housing 3, also comprise electronic type warning device 5, and the steam outlet pipe 2 of housing 3 is provided with the arm 6 that is communicated with steam outlet pipe 2, the free end of arm 6 is provided with and is used to trigger the flip flop equipment that electronic type warning device 5 starts, described flip flop equipment comprises sealing arm 6 free-ended diaphragms 7 and is arranged at free end side in the arm 6, with diaphragm 7 over against support 8, be fixed with respectively on support 8 and the diaphragm 7 over against the fixed contact 9 that is provided with, moving contact 10, and moving, fixed contact 10,9 are series in the current supply circuit of electronic type warning device 5.
During concrete enforcement, described electronic type warning device 5 can directly be arranged in the operator cabin, is more conducive to remind the driver should change or clean the maintenance air-strainer.
