Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

The utility model relates to a water/medicine online proportioning device, which is applied to a spray deodorizer, wherein the spray deodorizer comprises the water/medicine online proportioning device, an atomizing box 1, an atomizing device 2 and a water level switch valve 3.

The water/medicine on-line proportioning device comprises a dosing tank 4, a dosing pump 5, a pulse metering valve 6 and a driver 7; the dosing box 4 is used for containing medicaments; the inlet end and the outlet end of the dosing pump 5 are respectively communicated with the dosing tank 4 and the atomization tank 1; the inlet end and the outlet end of the pulse metering valve 6 are respectively communicated to a tap water source and the atomization box 1; the driver 7 is respectively electrically connected with the dosing pump 5 and the pulse metering valve 6 and is used for counting the pulse number generated by the water quantity flowing out of the pulse metering valve 6, and starting the dosing pump 5 to add the set dose of medicament when the pulse number reaches a set value;

the atomization device 2 is arranged in the atomization box 1 and is used for atomizing and spraying liquid medicine;

the water level switch valve 3 is arranged opposite to the outlet end of the pulse metering valve 6, is set to be in a normally closed state, and is opened for water supplement when the water level of the atomization box 1 is lower than a set value.

Referring to FIG. 1, a specific embodiment of the present invention is shown. (line in the figure represents circuit connection, line with arrow represents waterway connection and direction)

Above-mentioned atomizing device 2 is the high frequency atomizer, and it is littleer to realize atomizing spun granule, reaches better deodorization effect with the air mixing more easily to be difficult to cause the water route to block up, condense into the circumstances such as drop of water dripping.

The chemical feeding pump 5 is a DC12V direct-current speed-control diaphragm pump for pumping the chemical in the chemical feeding box 4 into the atomizing box 1.

The pulse metering valve 6 mainly collects water flow signals and outputs low-voltage pulses in a pulse form for counting, and according to different flow and precision requirements, a 17000/L pulse metering valve is adopted in the embodiment to realize precise control of proportioning; after counting the number of low-voltage pulses generated by the pulse metering valve 6, when the counted number of pulses reaches a set threshold, a low-level signal is output to the driver 7 to trigger the next device (i.e., the dosing pump 5).

The utility model also comprises a water level alarm device 8, wherein the water level alarm device 8 is arranged opposite to the atomization device 2, and the alarm water level is not lower than the inlet end of the atomization device 2. Water level alarm device 8 and 3 collocation uses of water level switch valve, water level switch valve 3 can realize that the water level in the atomizer box 1 under the normal condition is in the allowable fluctuation range of setting value all the time, and when taking place conditions such as pulse metering valve 6 damage, running water cuts off the water supply and lead to no longer adding water toward atomizer box 1, in case the water level of atomizer box 1 is less than behind the warning water level of water level alarm device 8, water level alarm device 8 sends out the police dispatch newspaper and reminds the staff in time to overhaul, avoid atomizer 2 idle running and then damage.
