Referring to fig. 1 and fig. 2, fig. 1 is a schematic block diagram of a nutritional solid soluble water dispenser 10 in the present embodiment, and fig. 2 is a schematic structural diagram of a particulate matter detection device 13 in the present embodiment.
The nutrient solid soluble type water dispenser 10 comprises a water dispenser body 11, a grinder 12, a particle detection device 13, a first electromagnetic valve 14, a second electromagnetic valve 15, an air flow system and a mixing box 16.
The water dispenser body 11 is provided with a water storage tank 110, a heating tank 111, a controller 112, and a water outlet 113.

Referring to fig. 3, grinder 12 has a feed opening 120, a feed inlet 121, and a pellet outlet 122. The operator puts the nutrient solid, such as dried Chinese angelica, ginseng or donkey-hide gelatin or other nutrient solid capable of being ground into powder, into the grinder 12 from the feeding port 120 for grinding. The ground particles or ground powder are discharged from the particle outlet 122 into the particle detector 13, and the particles that fail to be detected by the particle detector 13 enter the grinder 12 again through the feed inlet 121 for grinding.
Particulate matter detection device 13 has granule import, feed back mouth and dust export, and granule export 122 communicates with the granule import, and the feed back mouth communicates feed inlet 121 through first solenoid valve 14, and the dust export communicates mixing box 16 through second solenoid valve 15.

When the particle detecting device 13 detects that the particles in the air flow are larger than the preset size, the controller 112 controls the first electromagnetic valve 14 to be opened, so that the ginseng particles are ground by the grinder 12 again and discharged into the particle detecting device 13 along the air flow loop again through the action of the air flow system until the ginseng particles in the air flow detected by the particle detecting device 13 are equal to or smaller than the preset size (at this time, the particles are ground into ginseng powder conforming to the preset size), the controller 112 controls the second electromagnetic valve 15 to be opened, and the ginseng powder is discharged into the mixing box 16 and mixed with the water discharged into the mixing box 16 from the water storage tank 110, so that mixed water with nutrition is obtained. The mixed water may be controllably delivered through a valve structure to one of the intermediate heating tank 111 and the spout 113 for consumption by a person.
Referring to fig. 2, the particle detector 13 includes a housing 130, a light source 131, a photoelectric sensor 132, an airflow partition 133, and a reflow chamber 134.

The controller 112 calculates the size of the particles in the airflow based on the first temperature signal, the second temperature signal, and the electrical signal.
During the particle size detection operation, the heater 139 heats the air in the serpentine airflow channel, and the temperature of the air upstream and downstream of the heater 139 is different, and generally, the temperature detected by the first temperature sensor 137 is lower and the temperature detected by the second temperature sensor 138 is higher. The controller 112 can calculate the temperature difference between the air upstream and downstream of the heater 139 according to the temperatures detected by the two temperature sensors.

The controller 112 calculates the particle size based on the air flow value and the corresponding output electrical signal of the photoelectric sensor 132 after receiving the scattered light.
In the present embodiment, the air flow system is an air blowing structure disposed between the grinder 12 and the particle detector 13, the air blowing structure connects the particle outlet 122 of the grinder 12 and the particle inlet of the particle detector 13 through a pipeline, and provides an air flow along the direction from the particle outlet 122 of the grinder 12 to the particle inlet of the particle detector 13.
