Dust fullness reminding device of vacuum cleaner

Abstract

Disclosed is a vacuum cleaner fullness reminder which is characterized in that the vacuum cleaner fullness reminder comprises a reminder shell; an air inlet port connected with the outside is molded at the side face of one end of the shell, and an air outlet port communicated with a vacuum chamber is arranged at a position at a deflexion angle with the inlet port; a whistle which can give off reminding sound is connected with the air outlet port; correspondingly, a piston which isolates or communicates the air inlet port and air outlet port is installed at the cavity inside one end of the shell; one end of the piston is provided with an intake surface which presses in external air pressure; and a spring props up between the other end of the piston and the shell. The vacuum cleaner fullness reminder can not only remind when the vacuum degree of the vacuum chamber is too low and can also be automatically and duly communicated with the external air pressure to supplement air to get rid of the adverse factor that the vacuum degree of the vacuum chamber is too low. The vacuum cleaner fullness reminder is simple and practical and has components and is dispensed with an electronic circuit, low in cost, reliable and stable in performance and good in use effect.

Description

technical field [0001] The invention relates to a dust full reminding device for a vacuum cleaner. Background technique [0002] We know that vacuum cleaners are generally equipped with a vacuum chamber to absorb dust. Traditional vacuum cleaners are generally not equipped with a dust-full reminder device to remind whether the dust bag in the vacuum chamber is full of dust, which will affect people's normal use, so There are scientific and technical personnel to develop a reminding device to remind the vacuum degree of the vacuum cleaner, such as the Chinese patent "vacuum cleaner dust full automatic sound alarm device" as the patent No. 92237011. When the dust is full, the air pressure switch of the negative pressure sensor will make the light-emitting diode light up. When the dust is full and the blockage time is more than 10 seconds, the control circuit will make the audio circuit sound an alarm (language or music), and at the same time stop the electric fan, that is to s...

Problems solved by technology

Moreover, the dust-full reminder device of the traditional vacuum cleaner can only remind the alarm of the vacuum degree, but cannot timely eliminate the phenomenon of excessively low vacuum in the vacuum chamber, which requires manual processing to solve, and there are insurmountable disadvantages

[0003] Although there are alarm devices on the market that indicate the vacuum degree by color, in fact, people only pay attention to vacuuming during operation, and it is easy to ignore the color indicator, so the use effect is not ideal.
