Large Ultrasonic Humidifier

Analysis of the 9 common problems of humidifiers

Question 1: The fan noise of the humidifier does not turn and is damaged.

Analysis of the cause: The motor is not fixed reliably, causing the wind wheel to interfere with the air duct; if the wind resistance is too large, the speed will increase; the internal wiring will be disordered, causing the wire to interfere with the wind wheel.

The design should pay attention to: the design should consider the temperature resistance and strength, reliably fix the fan wind turbine air duct, add buffer if necessary; fully optimize the air duct, rational layout; structure reserved wiring position.

Question 2: Leakage at the seal of the transducer sheet

Analysis of the cause: The plastic parts are not flat or defective; after the repair, the screws slip and the sealing ring is not tightened.

The design should pay attention to: the plastic parts should avoid the water inlet at this place, otherwise the manual removal of the water nozzle will leave a defect, resulting in water leakage; the screw hole size is reasonably designed according to different materials.

Question 3: Water and water in the spray nozzle of the humidifier

Analysis of the cause: The most fundamental cause of water accumulation is caused by insufficient atomization; the water accumulated at the spray nozzle is caused by insufficient large particles of the water retaining plate; the water in the table area is often caused by insufficient spray height.

The design should pay attention to: improve the consistency of the performance of the transducer sheet; try to use a larger fog outlet when designing, and set the flap according to the shape of the mist outlet; under normal circumstances, the spray port height will reach 40cm. The water area of the station.

Question 4: Humidity display of the humidifier is not allowed

Analysis of the cause: The humidity sensor is not allowed to be displayed due to the environmental conditions.

The design should note that the humidity sensor is most sensitive to temperature, so the humidity sensor should be given a stable environment when designing.

Question 5: Plastic parts burn

Analysis of the cause: The components that cause burns include heating tubes, transducers, transformers, and motors.

The design should note that the design takes into account the gap between the plastic part and these components.

Question 6: Water level reed pipe rupture

Cause analysis: mostly caused by assembly, there are many reasons

The design should pay attention to: the design should make the structure reasonable and avoid the stress received during installation and fastening.

Question 7: The water tank leaks and is tightly tied to the frame

Analysis of the cause: The water leakage of the water tank is mostly caused by poor bonding and the looseness of the water cover; the tight connection between the water tank and the machine base is inconvenient due to the unreasonable size of the water tank.

The design should note that the effective thread ring that fits the water cover is preferably more than two turns; a reasonable clearance is reserved, preferably a tapered fit.

Question 8: The water tank of the humidifier is scratched and damaged

Analysis of the reasons: the water tank is mostly AS material, easy to pull and scratch; the damage of the water tank is mostly due to stress during injection molding, which leads to easy column.

Design should pay attention to: rational design of packaging materials; design symmetry when designing the water tank, to avoid sudden turning, the mold to avoid unbalance and avoid machining stress.

Question 9: The body is leaking, or leaking fog

Analysis of the cause: Most of the leakage of the fuselage leaked from the air outlet; the fog leakage of the fuselage was caused by improper setting of the water level and the air outlet, resulting in no sealing of the fog.

The design should pay attention to: the design of the site should fully consider the direction of the fog of the transducer sheet to arrange the air outlet; the windshield should be sealed by the air duct and the water level to completely avoid the leakage outside the fog to the improper area.
