The control unit 7 is internally preset with preset atomization rates which correspond to different liquid levels one by one, and the preset atomization rates can be automatically modified according to the needs of users or the environmental requirements of the atomization device, so as to meet the needs of different users and achieve the most appropriate control effect. The control unit 7 sets certain actual intervals of atomization, and the atomization time intervals can be set to be 1s, 2s, 3s, 4s, 5s, 6s and the like. The control unit 7 detects the first liquid level and the second liquid level in the atomization time interval according to the principle, calculates the actual atomization rate of the floating ball type atomization device according to the liquid level difference between the first liquid level and the second liquid level and the atomization time interval, compares the actual atomization rate with the preset atomization rate, transmits a rotation speed signal to the atomization motor 204, changes the rotation speed of the atomization motor 204, and adjusts the actual atomization rate.
In this embodiment, the control unit 7 adjusts the rotation speed of the atomizing motor 204 by changing the driving voltage of the atomizing motor 204, and if the actual atomizing rate is greater than the preset atomizing rate, the control unit 7 transmits a voltage reduction signal to the atomizing motor 204, and reduces the rotation speed by reducing the driving voltage of the atomizing motor 204; if the actual atomization rate is smaller than the preset atomization rate, the control unit 7 transmits a pressurization signal to the atomization motor 204, and increases the rotation speed by increasing the driving voltage of the atomization motor 204.
Still arranged display screen 8 on bottle 2, display screen 8 and the display module 201 signal connection of the control unit 7, display screen 8 are used for receiving and show the liquid level signal and the atomizing rate signal of the control unit 7 transmission, the actual rotational speed of feedback atomizing motor 204.
The working process of the invention is as follows: the power cord is connected to the power interface 5, the output port 6 is connected with the atomizing motor 204, the switch button 4 is started, the floating ball type atomizing device starts to atomize, the atomizing motor 204 pumps atomized liquid in the bottle body 2 to the external environment, and the actual atomizing rate of the atomizing device is always kept at the preset atomizing rate to atomize by means of closed-loop control of liquid level-atomizing motor rotating speed.
When the control unit 7 detects the liquid level and adjusts the rotating speed of the atomizing motor 204, the method comprises the following steps:
step 301, an operator inputs a preset atomization rate according to a use environment. The preset atomization rate can be automatically modified according to the requirements of users or the environmental requirements of the atomization device, so as to meet the requirements of different users and achieve the most appropriate control effect.
Step 302, the control unit 7 is set to read the atomization time interval of the liquid level.
A certain atomization time interval is set, and the control unit 7 reads the liquid level of the mixed liquid in the bottle bodies at the head end and the tail end of the atomization time interval. The atomization time interval may be set to 1s, 2s, 3s, 4s, etc. The size of the atomization time interval determines that the closer the total actual atomization time is to the preset atomization time, the shorter the atomization time interval is, the closer the total actual atomization time is to the preset atomization time, but the more calculation of the required program is, the more appropriate atomization time interval should be selected. In the embodiment of the present invention, the atomization time interval is set to 5 s.
Step 303, the control unit 7 obtains a first liquid level. The control unit 7 reads the liquid level at the head of the set atomization time interval as the first liquid level. When the floating ball type atomization device starts atomization, the control unit 7 takes the liquid level of the mixed liquid 203 in the bottle body 2 as a first liquid level.
In step 304, the control unit 7 determines whether the first level is zero.
The specific determination method is that when the liquid level h is zero, no medium is conducted between the floating ball 9 and the metal probe 10, so that the control unit 7 detects that no current flows between the floating ball 9 and the metal electrode, namely, the resistance R between the floating ball 9 and the metal electrodexInfinite, output voltage
Figure BDA0002645134370000091
Step 305a, if the first liquid level is not zero, the control unit 7 inputs a driving voltage to the atomizing motor 204 according to a preset atomizing rate, and the atomizing motor 204 is started in a matching manner with a corresponding rotating speed.
According to the atomization rate set by the user, the control unit 7 automatically matches the corresponding rotation speed of the atomization motor 204, and the rotation speed of the atomization motor 204 can achieve the purpose by controlling the driving voltage of the motor.
Step 305b, if the first liquid level is zero, the control unit 7 controls the atomizing motor 204 to stop working, and the control unit 7 reminds the user to add liquid through the display screen 8 and the alarm.
In step 306, the control unit 7 obtains a second liquid level.
The control unit 7 reads the liquid level of the mixed liquid 203 in the bottle 2 after the atomization time interval, and takes the liquid level as a second liquid level, that is, the liquid level at the end of the set atomization time interval is taken as the second liquid level.
In step 307, the control unit 7 determines whether the second level is zero. The judging method is consistent with the judging method of the first liquid level.
Step 308a, if the second liquid level is not zero, the control unit 7 calculates the actual atomization rate according to the liquid level difference between the first liquid level and the second liquid level and the atomization time interval.
The actual rate of atomization is calculated by dividing the difference between the first and second levels by the time it takes for the level of the liquid atomized in the bottle 2 to atomize from the first level to the second level, i.e., the set atomization time interval.
And 308b, if the second liquid level is zero, stopping the work of the atomizing motor 204, and reminding a user to add liquid through the display screen 8 and the alarm.
Step 309, the control unit 7 compares the actual atomization rate with a preset atomization rate, adjusts the driving voltage of the atomization motor 204, and the atomization motor 204 continues to atomize at the preset atomization rate.
If the actual atomization rate is greater than the preset atomization rate, the control unit 7 transmits a voltage reduction signal to the atomization motor 204, and reduces the rotation speed by reducing the driving voltage of the atomization motor 204. If the actual atomization rate is smaller than the preset atomization rate, the control unit 7 transmits a pressurization signal to the atomization motor 204, increases the rotation speed by increasing the driving voltage of the atomization motor 204, and continues atomization when the driving voltage is adjusted.
Finally, steps 303-309 are repeated in sequence until atomization is complete.
To sum up, the embodiment of the present invention provides a floating ball type atomization device, wherein when the liquid level of the atomized liquid changes, the ratio of different solutions in the mixed solution changes, and the concentration of conductive ions in the solution changes, so that the conductivity of the mixed solution changes; the polarity of the floating electrode is opposite to that of the fixed electrode, the height of the floating electrode changes when the liquid level changes, the control unit detects the numerical value of the conductivity between the floating electrode and the fixed electrode, so that the liquid level of the mixed solution is determined, the actual atomization rate can be obtained according to the change rate of the liquid level, the control unit compares the actual atomization rate with the preset numerical value of the atomization rate and transmits a rotating speed signal to the atomization motor, the rotating speed of the atomization motor is adjusted, the closed-loop control of the liquid level and the rotating speed of the atomization motor is realized, the self-adaptive adjustment of the atomization rate is realized, the same solute concentration is output under different liquid levels, and the physical health of.
