Description

Technical Field

[0001] The utility model belongs to the technical field of spray equipment, and more specifically relates to a spray machine with the function of automatically replenishing essential oil. Background Art

[0002] A high-pressure sprayer is an air-compressed atomizer that uses compressed air to form a high-speed airflow through a small nozzle. This high-speed airflow will generate negative pressure when passing through the nozzle, thereby driving liquid or other fluids to be sprayed onto the obstruction. Under high-speed impact, the liquid splashes around, turning the droplets into mist particles. These mist particles are then ejected from the outlet pipe.

[0003] As shown in the Chinese utility model patent with announcement number CN211672074U, it records an air-conveying remote high-pressure pesticide sprayer, whose structure includes a barrel, an adjustment device, a spray barrel, a rotating shaft, a fixing rod, a supporting rod, a main frame, a connecting hinge, an inspection cover, a mobile caster, a rotating disk, and a mounting plate. The barrel is installed above the main frame, and the inspection cover is fitted with the main frame. During the spraying process, the start of the small motor is controlled by the control panel to drive the transmission half gear to rotate, so that the piston rod meshing with it moves, and through two one-way valves, when the piston rod moves upward, the internal oil pushes the adjustment rod to move upward, so that the barrel is lifted up, and when the piston rod moves downward along the protective shell, the oil will return to the bottom through the one-way valve to make the adjustment rod move downward together, thereby reducing the angle of the spray barrel.

[0004] The existing sprayer has a basically the same structure as the above-mentioned sprayer. Air purification can be achieved through the combination of essential oil and the sprayer. However, one of its defects is that it does not have the function of automatically replenishing essential oil. After the sprayer has been used for a period of time, essential oil needs to be added manually, the endurance is poor, and it is inconvenient to use. Utility Model Content

[0065] The controller of this embodiment may be a PLC controller installed on the machine body 1 to realize the control of the circuit and the gas circuit.

[0066] The working principle of the sprayer with automatic essential oil replenishment function of this embodiment is:

[0067] When in use, the concentrated essential oil tank 51 is filled with concentrated essential oil, which needs to be mixed with water when in use. The setting of the essential oil replenishing device 5 can automatically complete the replenishment operation of the concentrated essential oil, and the setting of the essential oil diluting device 4 can automatically complete the dilution of the concentrated essential oil. The specific working process is as follows:

[0068] S1, as the sprayer 3 continues to use the essential oil liquid in the liquid storage tank 41, when the first liquid level sensor 54 detects that the liquid level in the liquid storage tank 41 is lower than the first liquid level L1, a feedback signal is sent to the controller, and the controller controls the electric valve 53 to open, so that the concentrated essential oil in the concentrated essential oil tank 51 enters the liquid storage tank 41 through the first connecting pipe 52, and is replenished until the liquid level in the liquid storage tank 41 is higher than the second liquid level L2;

[0069] S2, when the second liquid level sensor 55 detects that the liquid level in the liquid storage tank 41 is higher than the second liquid level L2, a feedback signal is sent to the controller, and the controller controls the electric valve 53 to close and stop inputting concentrated essential oil;

[0070] S3, the essential oil dilution device 4 starts working. When the liquid level in the liquid storage tank 41 is higher than the second liquid level L2 and the electric valve 53 is closed, the controller controls the solenoid valve 44 to open, and water enters the liquid storage tank 41 through the water pipe 43 and the mixer 42 in sequence, and is replenished until the liquid level in the liquid storage tank 41 is higher than the third liquid level L3;

[0071] S4. When the third liquid level sensor 45 detects that the liquid level in the liquid storage tank 41 is higher than the third liquid level L3, a feedback signal is sent to the controller, and the controller controls the solenoid valve 44 to close and stop inputting water. During the replenishment process, water is continuously output from the mixer 42 and mixed evenly with the concentrated essential oil to obtain essential oil liquid for standby use.

[0072] The sprayer of this embodiment has at least the following advantages over the spray equipment on the market:

[0073] An essential oil replenishing device 5 and an essential oil diluting device 4 are provided. The essential oil replenishing device 5 can automatically replenish the concentrated essential oil when the essential oil liquid in the liquid storage tank 41 is about to be used up, and then cooperate with the essential oil diluting device 4 to directly prepare the diluted essential oil liquid suitable for spraying operation in the liquid storage tank 41, which is not only low in cost but also can greatly extend the use time of the sprayer.
