Description

Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to an airflow sensor and atomization equipment. Background Art

[0002] Atomizer is a device that atomizes liquid substances into small particles. It produces mist substances by generating high-speed airflow. Atomization can be used in many aspects such as spraying, spraying, drying, etc. in industrial processes. It is also widely used in agriculture, such as spray irrigation, insecticide, sterilization, etc., to atomize pesticides or fertilizers into very small particles to improve absorption effect and reduce pollution to the environment.

[0003] The invention with announcement number CN114947240A discloses an atomizing device, including a main body and a base. The upper end of the main body is provided with a mist outlet, and the lower end is open. An atomizing assembly and a power supply electrically connected thereto are provided inside the main body. The power supply drives the atomizing assembly to atomize the solution to be atomized stored therein, and the generated aerosol is discharged from the mist outlet. The base includes a seat body provided with an installation space, a circuit board fixed in the seat body, and a sealing cover; the seat body is plugged into the opening by interference sealing, and a charging plug port and an air inlet connecting the outside and the installation space are provided on the lower end surface of the seat body; a charging plug socket is electrically integrated on one side of the circuit board, and is correspondingly plugged into the charging plug port; the sealing seat is sleeved on the outer periphery of the charging plug socket, and its lower end seals the edge of the inner side of the charging plug port, and the upper end elastically interferes with the circuit board; the air inlet is connected to the internal atomizing gas path airflow of the atomizing assembly;

[0004] The above technical solution, by opening a charging insertion port and an air inlet on the lower end surface of the seat body, allows the circuit board to be away from the atomization component, reduces the condensate and waste liquid generated by the atomization component from leaking into the circuit board and causing damage to the circuit board, and the sealing seat prevents external airflow from flowing in from the gap between the charging insertion port and the charging socket, so that the external airflow only flows into the interior of the main body through the air inlet and is precisely controlled, thereby ensuring the consistency of the product's suction resistance and taste quality; however, the power supply drives the atomization component to atomize the solution to be atomized stored therein, which is not convenient for continuous solution delivery and coordination, and it is not convenient to adjust the size of the atomized particles during atomization.

The spring 182 has telescopic elasticity, which helps the sealing column 183 to return to its initial position.

[0082] When the atomizing device of this embodiment is used, the user first plugs the piston rod 111 with the rubber pad 1110 into the squeeze box 10 with the liquid level window 12 through the movable rod 11, and the housing 20 with the drive motor 21 is assembled with the squeeze box 10, and the rotating shaft 22 with the crankshaft 220 is coaxially connected with the output shaft of the drive motor 21, and then one end of the connecting rod 23 is rotatably connected to the crankshaft 220, and the other end is rotatably connected to the hinge seat 110 at the top of the movable rod 11, and the connecting box 50 with the air inlet pipe 51 is connected to the right side of the housing 20, and the rotating shaft 22 extends into the connecting box 50, and the fan blade 221 is sleeved on the connecting box 50. On the internal rotating shaft 22, the guide ring 53 with the guide hole 530 is fixed inside the connection box 50, and then the nozzle 4 and the disperser 61 are installed at the right end of the connection box 50, and the cylinder 70 with the adjustment hole 72 is threadedly connected to the right end of the connection box 50. The top cover 32 with the air inlet pipe 321 and the water inlet bucket 323 is plugged and matched with the water storage tank 30 with the transparent window 300, one of the blocking pieces 18 is installed on the inner side of the water outlet 16, and the other blocking piece 18 is installed on the outer side of the water inlet 17. The water storage tank 30 is connected to the delivery pipe 15 at the water inlet 17 through the guide pipe 31, and the delivery pipe 15 at the water outlet 16 is connected to the nozzle 4;

[0083] Working principle: the driving motor 21 is connected to the external power supply, the output shaft rotates to drive the rotating shaft 22 to rotate, and then drives the crankshaft 220 to rotate, the connecting rod 23 rotates around the crankshaft 220, drives the movable rod 11 to move up and down, and then prompts the piston column 111 with the rubber pad 1110 to move inside the extrusion box 10, state one: when the crankshaft 220 rotates to the highest point, the piston column 111 moves to the top of the extrusion box 10, under the pressure change, the pressure at the bottom of the extrusion box 10 decreases, and the internal pressure balance is maintained, wherein the sealing column 183 in the sealing member 18 at the water outlet 16 is tightly plugged and sealed with the water outlet 16, wherein the sealing member at the water inlet 17 Under the action of pressure, the sealing column 183 in 18 moves upward, so that the bottom of the extrusion box 10 extracts the solution inside the water storage tank 30 through the guide pipe 31. State 2: When the crankshaft 220 rotates to the lowest point, the piston column 111 moves to the lower part of the extrusion box 10, and the internal pressure is balanced under the pressure change, wherein the sealing column 183 in the plugging member 18 at the water outlet 16 is separated from the water outlet 16, and the sealing column 183 moves downward, so that the solution inside the extrusion box 10 is discharged from the nozzle 4, wherein the sealing column 183 in the plugging member 18 at the water inlet 17 is tightly plugged and blocked with the water inlet 17 under the action of pressure;

[0084] The faster the output shaft of the driving motor 21 rotates, the faster the pumping and draining frequency inside the extrusion box 10 is. With the cooperation of the fan blades 221, the air circulation inside the connection box 50 is accelerated. With the cooperation of the guide holes 530, the air inside the connection box 50 is forced to rotate and be discharged to the right, thereby accelerating the internal ventilation and increasing the spraying of the solution at the end of the nozzle 4. On the contrary, the slower the output shaft of the driving motor 21 rotates, the lower the pumping and draining frequency is, the slower the air circulation inside the connection box 50 is, and the slower the atomization spraying is.

[0085] During the working process, without interrupting the overall operation, the atomized solution is continuously replenished through the water inlet 323. With the cooperation of the water inlet pipe 13, the spray solution is replenished into the extrusion box 10, which helps to maintain the pressure balance inside the extrusion box 10 in the initial state, and is convenient for pumping or draining. The cylinder 70 is threadedly connected to the right end of the connection box 50 with the cooperation of the external thread 60. According to the size of the atomized particles required, the cylinder 70 is close to the connection box 50, the gap between the adjustment hole 72 and the disperser 61 is reduced, and the solution passing pressure is increased, which helps to accelerate the atomization and spraying of the solution, and the atomized particles are reduced. When the cylinder 70 is away from the connection box 50, the gap between the adjustment hole 72 and the disperser 61 is increased, the solution passing pressure is reduced, and the atomized particles are increased;

With the cooperation of the connecting ring 52, it is convenient to combine the air shell 6 and the right end of the connection box 50 for installation. The adjustment distance between the adjustment hole 72 and the disperser 61 will not change due to the increase of the shell 6. With the cooperation of the shell 6, the air inside the connection box 50 continues to pass through the inside of the shell 6, and the air intake in the middle of the shell 6 changes the resistance of the air flow meter, changes the current, and converts the inhaled air flow into an electrical signal and sends it to the chip 62 control unit, thereby realizing the detection of the amount of air passing through.
