(1) humidification mechanism

It includes a main water tank that meets the water volume required for one cleaning. The main water tank has a built-in ultrasonic atomizer, and the water mist is guided to the front end of the cleaning mechanism and the wiping mechanism of the sweeper through the water mist pipeline. The cleaning process includes: vacuuming first, then humidifying, then cleaning and wiping, which can remove dust and stains and improve the cleaning effect. The humidity of the water mist can be adjusted by adjusting the power of the ultrasonic nebulizer. Users can choose to automatically or manually adjust the reasonable humidity to achieve the best cleaning effect. The humidification function can also be turned off.

(2) Spray mechanism.

The water spray device has a separate water spray chamber connected to the main water tank through a solenoid valve, and the conduction time of the solenoid valve determines the amount of water sprayed.

The air pressure at the air outlet of the vacuum cleaner activates the water spray. When the vacuum cleaner is working, negative pressure is generated at the suction port and positive pressure is generated at the air outlet. When spraying water is required, open the air outlet to the electromagnetic valve of the water spray chamber, and the air pressure at the outlet of the vacuum cleaner will form a spray pressure in the water spray chamber, and spray water to the front end of the cleaning mechanism of the cleaning machine, using the momentum of water and cleaning The chemical action of the agent moisturizes and loosens the stains, and the subsequent cleaning mechanism and wiping mechanism are responsible for cleaning to complete the entire cleaning process.

If the air pressure water spraying device is not used, it is also possible to directly use a high-pressure water pump to absorb water from the main water tank or connect an external water pipe to form a spray.

The humidification mechanism and the water spray mechanism are placed in front of the C-shaped front baffle to prevent the diffusion of water vapor and water splashes.

The working process of the cleaning machine is:

(1) The rotary dust collection device rotates, and the vacuum cleaner works while sweeping the dust, absorbing and cleaning the dust and sundries; the sundries are rolled into the dustbin. Dust is sucked through the suction hole and enters the dust cavity of the vacuum cleaner.

Choose one of steps (2) and (3):

(2) When water spraying is required. In the following order:

A) Close the electromagnetic air valve, open the electromagnetic water valve, and put an appropriate amount of water into the water spray chamber according to the water spray volume requirements;

B) Close the electromagnetic water valve, open the electromagnetic air valve, the air pressure at the exhaust port of the vacuum cleaner is transmitted to the water spray chamber through the water spray air pressure branch pipe, and the water flows through the water spray pipe to spray to the working surface.

(3) When spray humidification is required. The ultrasonic atomizer is powered on, and the power is adjusted with the power adjustment knob to adjust the humidity of the water vapor output through the same water mist pipe.

(4) The wiping sponge rotates to wipe off the stains diluted and dissolved by water on the ground, and the dirty water on the sponge is collected by the dirty water absorption device.

(5) After steps (1)-(4), a cleaning process is completed. When the cleaning machine is advancing, the above process is constantly repeated.

In addition to the method of ultrasonic atomization, several other methods can be used to achieve air humidification.

1. Replace the ultrasonic nebulizer with a pure humidifier. Pure humidification technology can also remove calcium and magnesium ions in water through molecular sieve evaporation technology, completely solving the problem of "white powder". There is neither "white powder" phenomenon nor scaling, and the power is small.

2. Replace the ultrasonic nebulizer with a thermal evaporation humidifier. Its working principle is to heat water to 100 degrees in the heating body, generate steam, and send the steam out with a fan. The disadvantages are high energy consumption, no dry burning, low safety factor, and easy fouling on the heater.

3. The ultrasonic atomizer is replaced by the water pump method, and the water in the condensation water tray is pumped through the water pump and then sprayed to the air outlet, and the water mist is realized at the air outlet to achieve the purpose of humidification.

4. Use a high-pressure water pump to replace the air pressure at the air outlet of the vacuum cleaner to activate the water spray method.

Referring to Fig. 2, Fig. 2 is a block diagram of the control system of the adjustable humidifying water spraying device for the cleaning machine, and the functions of each main functional module are as follows:

(1) The power module provides power for each part;

(2) The microcontroller reads the water level and temperature signals in the water tank. When heating is required, the relay is turned on to make the electric heating element work and heat the water in the water tank to an appropriate temperature;

(3) The operation panel and display device are the human-computer interaction mechanism of the cleaning machine;

(4) Four PWM signals, respectively control the work of the traveling motor, cleaning motor, wiping motor and atomizer;

(5) Two relays respectively control the switch of the electromagnetic water valve and the electromagnetic air valve;

(6) The system is equipped with a voice prompt function to reduce the difficulty of operation.
