Abstract
The utility model discloses a kind of filter and change alarm set, described air filter is arranged in the groove of upper cover, removable cover is stuck in and covers, air filter is fixed, described circuit board is arranged on down and covers, and described circuit board is provided with dust investigating and gas-detecting device, and described motor is arranged on the centre position of lower cover, described lower cover is stuck in the bottom of upper cover, and circuit board and motor are wrapped in the inside of lower cover and upper cover.Alarm set changed by this filter, sensing device and gas detect sensing device is detected by installing dust additional in clarifier inside, thus can judge the need of replacing filter accurately, when needing to change, the mode reminding user to replace such as clarifier can be sounded by loudspeaker, indicator lamp, display screen display.
Description
Technical field
The utility model relates to filter technology field, is specially a kind of filter and changes alarm set.
Background technology
The filter (being generally made up of HEPA, active carbon, photocatalyst, silver ion, cold catalyst, electrostatic case etc.) of air purifier, its quality directly will have influence on clean-up effect.Filter needs irregular replacing or cleaning, and environment for use air quality is different, and the time of use is also different.Judge whether that the method needing to change filter has two kinds: the first at present, changed by the dirty degree of filter that visually observes of people.Shortcoming is: 1, judge with the subjective sensation of people completely, and be difficult to set up unified standard, error is very large.2, people can only judge the saturation degree of filter dust, and various toxic gas also can be adsorbed on filter, and the naked eyes of saturated people but cannot judge.The second, the time adding up to use by calculated device judges (regularly) such as 500 hours.Shortcoming is: 1, due to the environment difference that clarifier uses, the time that filter is changed also is different.Such as, same specification clarifier, one uses in bedroom, and another uses in office.Because clerk is more, the life-span (time) that clarifier filter uses is certain to a lot short.So timing is changed filter and is and unscientific, the waste of filter and the situation of secondary pollution can be caused to occur.
Utility model content
The purpose of this utility model is to provide a kind of filter to change alarm set, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: alarm set changed by a kind of filter, comprise removable cover, air filter, upper cover, circuit board, motor and lower cover, described air filter is arranged in the groove of upper cover, removable cover is stuck in and covers, air filter is fixed, described circuit board is arranged on down and covers, described circuit board is provided with dust investigating and gas-detecting device, described motor is arranged on the centre position of lower cover, described lower cover is stuck in the bottom of upper cover, circuit board and motor are wrapped in the inside of lower cover and upper cover.
Preferably, described dust investigating coordinates by jack and latch the left lower being arranged on upper cover.
Preferably, described circuit board is electrically connected with display screen, and display screen spills lower cover and upper cover.
Preferably, described circuit board is provided with single-chip microcomputer, and described dust investigating and gas-detecting device are connected in series on circuit boards, and described circuit board also electrically picks out motor, indicator lamp and loudspeaker, and the circuit that picks out of motor is provided with a control valve, for controlling motor operation.
Compared with prior art, the beneficial effects of the utility model are: alarm set changed by this filter, sensing device and gas detect sensing device is detected by installing dust additional in clarifier inside, the fine or not degree (concentration of dust concentration and toxic gas) of detection air quality that can be real-time, and the service time of the data detected and filter is carried out scientific and reasonable computing, thus can judge the need of replacing filter accurately, when needing to change, clarifier can be sounded by loudspeaker, indicator lamp, the mode reminding user to replace such as display screen display.
