Description

The efficient ultrasonic atomizer

Technical field

The utility model relates to a kind of atomizing utensil, especially for the ultrasonic ultrasonic delay line memory of sterilization or humidifying air, belongs to the atomising device technical field.

Background technology

Atomising device be with liquid to atmosphere or indoor discharge droplet to form the device of vaporific or analog, it has purposes very widely in industry, medical and health and life.Such as spraying disinfection, humidifying air, its importance is not only well-known, and range of application is more and more wider.The press atomization that tradition is used utilizes High-Pressure Water bump air or high pressure draught bump current, and current are ground into droplet and are sprayed by nozzle.Droplet that this class mechanical impact method is produced, its diameter is roughly about 50 microns, and the major diameter droplet is difficult in aerial floating delay, has influenced the effect of air wetting, sterilization.Discover that water can atomize under the vibration of 1700 khz frequencies, the droplet that ultrasonic atomizatio produced, its diameter are the 1-5 micron only, and fog is soft, can floating aloft for a long time delay.Ultrasonic atomizatio noiseless, pollution-free, and be swift in response, from the inactive state to the rated value, only need 0.8 second, produce 1 kilogram of mist and only need 0.1 degree electricity, very energy-conservation.All advantages of ullrasonic spraying have made it develop into an industry.But ultrasonic atomizatio requires transducer apart from the size of liquid level strict requirement to be arranged, and is generally about 40mm, and size difference can influence its nebulization efficiency.For this reason, the core of ultrasonic atomizer must be provided with water level automatic control device, someone had once designed a kind of multi-functional atomization disinfection device, its main composition is ultrasonic atomizatio sheet, blower fan and liquid-storage box, liquid-storage box is communicated with the ultrasonic atomizatio chamber by valve, the sterilization soup is housed in the spray chamber, sprays after with medical liquid atomizing, article are carried out disinfection by atomising device.In use, frequent Open valve to dose soup, make liquid level and transducer keep certain distance with the continuous ejection of mist body, one time liquid feeding can not be too much, avoid transducer and liquid level distance excessive, influence the normal operating conditions of sterilizer, it is very inconvenient therefore to use.The atomizer that also has, liquid level adopts fluid infusion pump and Electronic Control, and its consequence is that mechanism's complexity, cost increase.

Summary of the invention

Technical problem to be solved in the utility model is: overcome the defective of above-mentioned prior art and provide a kind of simple and can reliably control the efficient ultrasonic atomizer of transducer and liquid level distance.

The alleged problem of the utility model is solved by following technical scheme:

A kind of efficient ultrasonic atomizer, comprise housing, spray chamber, transducer, blower fan, spray chamber is arranged in housing, transducer is set in the spray chamber, transducer immerses in the liquid, blower fan is communicated with pipeline with spray chamber, and its special feature is: set up float mechanism, described float mechanism is by supporting plate, float is formed, float is fixed on the supporting plate, described transducer and spray chamber all are fixed on the supporting plate, and the distance that keeps between transducer and the liquid level is set by float, and the upper end of spray chamber is communicated with two pipelines and leads to hull outside, article one, be intake stack, another is a spray pipe, two pipelines all with the spray chamber servo-actuated, described blower fan is arranged on the blast pipe road junction.

Above-mentioned efficient ultrasonic atomizer, be equipped with interface on described intake stack and the spray pipe, be connected to intake stack in the air intake interface, the spraying interface is external in spray pipe, described two interfaces are all fixed with housing, and two interfaces form with two pipelines respectively and are slidingly connected.

Above-mentioned efficient ultrasonic atomizer, the mouth of pipe and the housing of described intake stack and spray pipe are fixed, and scalable corrugated flexible hose is adopted at the middle part of two pipelines.

Above-mentioned efficient ultrasonic atomizer is provided with baffle plate in the described housing, and two baffle plates vertically are arranged on the both sides of float mechanism.

Above-mentioned efficient ultrasonic atomizer, described housing is provided with link plate or bearing.

The efficient ultrasonic atomizer of the utility model design utilizes float mechanism can control the distance of transducer and liquid level easily and reliably.It has overcome the control device baroque weak point that atomizer in the prior art needs continuous human intervention liquid level or employing, no matter topping up what, transducer and liquid level remain optimum distance, and therefore, described atomizer is always operating in the state of high-efficient atomizing.Can once be full of soup during use, long-time continuously the use.The utility model is simple in structure, and is reasonable in design, is suitable for the usefulness of air sterillization in the various occasions, humidification, and the atomizing utensil that also can be used as other liquid uses.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of another embodiment of the utility model.

The specific embodiment

Referring to Fig. 1, formation of the present utility model comprises housing 1, spray chamber 2, transducer 3, blower fan 4, and transducer is dipped in the thimerosal 13.Set up float mechanism, float mechanism is made up of supporting plate 5, float 6, and it is hollow that float can be designed to ring-type, also can be designed to a plurality of floats and evenly be fixed on the supporting plate, and transducer and spray chamber are fixed on supporting plate middle part, spray chamber should be positioned at transducer directly over.The upper end of spray chamber is communicated with two pipelines and leads to hull outside respectively, and one is intake stack 8; Another is a spray pipe 7.Float and supporting plate adopt light material to make.During transducer work, should keep a rational distance with liquid level, this distance is if bigger, and the fog-like body that is inspired by transducer can be absorbed by liquid, influences nebulization efficiency.The key point of this design is: the buoyancy of appropriate design float, transducer not only had been dipped in the liquid but also keeps the atomization distance an of the best with liquid level, float, supporting plate drive spray chamber, transducer rises synchronously or descends with liquid level, no matter liquid level just, the distance between transducer and the liquid level is constant all the time, therefore, described atomizer is always operating in the state of high-efficient atomizing, and atomizing effect is good, and medicine droplet footpath is light thin, suspension time is long in air, and sinking speed is slow.Can once be full of soup during use, long-time continuously the use is depleted to bottom line until soup, needn't repeatedly add liquid midway.

When float, supporting plate move with liquid level, air intake passage that is communicated with spray chamber and spray channel synchronous follow-up.For this reason, the utility model has designed two kinds of schemes, scheme shown in Figure 1, described two pipelines all adopt connected structure, be respectively equipped with air intake interface 10 and spraying interface 9, the size of two interface sizes and pipeline joint is complementary and can forms and is slidingly connected, and joint should not cause the resistance of motion when pipeline moved up and down.Scheme shown in Figure 2, scalable corrugated flexible hose 16 is adopted at the pipeline middle part, and flexible pipe ripple place should guarantee capable of expansion and contraction, to satisfy the needs that spray chamber fluctuates.Baffle plate 17-1,17-2 play position-limiting action in the time of can be to the float mechanism kinematic.

Blower fan 4 is installed on the fixed cap 15 that is connected with case top lid, and blower fan is positioned at place, blast pipe road junction.Housing is provided with filling opening 13, is convenient and installs that the utility model also is provided with link plate 12 and support 14, and low power atomizer can hang over it on wall, and powerful atomizer can utilize support 14 that it is laid in place.
