Technical field
The present invention relates to a kind of ultrasonic atomizer device, it is 3.0MHz or 5.0MHz and the ultrasonic atomizer device that contains one or more piezoelectric patches that You Zhiyi has the concussion frequency.
Background technology
The ultrasonic atomizer device is to utilize concussion power drives one piezoelectric patches (piezoelectric ceramic oscillator) producing mechanical oscillation, and vibrational energy is coupled in the liquid and at liquid surface produces capillary ripple (capillary wave) to produce the ultrasonic droplet.This droplet can be used for drug therapy or produces moisture.Its concussion frequency of existing ultrasonic atomizer is generally 1.6MHz or 2.4MHz.As shown in Figure 1, the average grain diameter size of 1.6MHz or 2.4MHz droplet that ultrasonic atomizer produces is about 2.3 μ m and 1.7 μ m respectively.Be applied to when the lung administration, these two kinds of its mist droplet particle sizes of atomizer are excessive.General mist droplet particle size size need approximately is easier to enter alveolar region less than 1.0 μ m and then is absorbed; And it is promptly adsorbed by bronchus or bronchiole easily before entering alveolar greater than the droplet of 1.0 μ m.Because of ultrasonic atomizer, as shown in Figure 1, existing concussion frequency is that time micron droplet total amount that ultrasonic atomizer produced of 2.4MHz is extremely rare, and absorbed droplet amount is also relatively extremely rare so can enter alveolar region at last.Yet in the time of the concussion frequency of atomizer if can being increased to 5MHz, as shown in Figure 1, time micron droplet total amount that this moment, ultrasonic atomizer produced just can improve in a large number, to improve result of treatment.Therefore, aforementioned existing ultrasonic atomizer device has improved necessity really.
As shown in Figure 1, when the concussion frequency is increased to 3.0MHz, its average grain diameter that produces droplet can be reduced to 1.5 μ m.When the concussion frequency is increased to 5.0MHz again, more average grain diameter can be reduced to about 1.0 μ m, and the ratio of time micron droplet also improves in a large number at this moment.Yet when the concussion frequency of piezoelectric patches is increased to 5.0MHz, though can improve time ratio of micron droplet in a large number, the spray amount that is produced this moment also relatively reduces.
Summary of the invention
The purpose of this invention is to provide a kind of ultrasonic atomizer that produces high-load time micron droplet, its concussion frequency is 3.0MHz or 5.0MHz, and contains one or more piezoelectric patches, the problem of spray amount deficiency when being 3.0MHz or 5.0MHz to overcome the concussion frequency.The concussion frequency is that the ultrasonic atomizer of 5.0MHz can produce average grain diameter at 1.0 μ m, and contains the droplet of time micron at high proportion.
The present invention is intended to improve the average grain diameter size of the concussion frequency of ultrasonic atomizer with the reduction droplet, and a large amount of time ratio of micron droplet that improves.
For reaching aforesaid purpose, the ultrasonic atomizer device that a tool of the present invention produces high-load time micron droplet mainly comprises: an ac/dc conversion equipment, and it is to convert alternating voltage to DC voltage, so that an operation DC voltage to be provided; One oscillating circuit, it produces the required concussion frequency of piezoelectric patches; One power amplifier device, it should shake frequency and be amplified; One concussion liquid storaging device, it has a container to store the liquid of desire atomizing; At least one piezoelectric patches is to be positioned at this container bottom below, is that the oscillator signal that is connected to after this amplifications shakes to produce.
The present invention constructs novelty, can provide on the industry to utilize, and can promote effect really.
For further understanding structure of the present invention, feature and purpose thereof, conjunction with figs. and specific embodiment, describe in detail as after.

The specific embodiment
The ultrasonic atomizer device of relevant high-load of the present invention time micron droplet, please be earlier with reference to shown in Figure 2, wherein, this ultrasonic atomizer device with high-load time micron droplet has an ac/dc conversion equipment 21, an oscillating circuit 22, a power amplifier device 23, concussion liquid storaging device 24 and at least one piezoelectric patches 25.
It is to convert an alternating voltage to a direct current voltage for this ac/dc conversion equipment 21, to provide a direct current voltage to this oscillating circuit 22, it is 3.0MHz or 5.0MHz that this oscillating circuit 22 produces the required concussion frequency of piezoelectric patches, the signal that will shake frequency via power amplifier device 23 is amplified, at least one piezoelectric patches 25 is to be positioned at this below, concussion liquid storaging device 24 bottoms, its oscillator signal that is electrically connected to after this amplification shakes to produce, this concussion liquid storaging device 24 is to store liquid to be atomized, produces the ultrasonic droplet because of the piezoelectric patches of its bottom produces to shake.
An exemplary circuit diagram of ultrasonic atomizer device that shows the high-load time micron droplet of present embodiment as Fig. 3, in Fig. 3, ac/dc conversion equipment 21 by 4 diode D1-D4, and 1 resistance R 6 formed, diode D1-D4 forms a Qiao Shi fairing and is used for producing a direct current voltage; Oscillating circuit 22 is made up of resistance R 1-R3, capacitor C 1-C3, a variable resistor VR1 and a concussion transistor OSC1, to produce the required concussion frequency of piezoelectric patches; Power amplifier device 23 is made up of resistance R 5, capacitor C 4-C6, inductance L 1-L2, diode D5 and power amplifying transistor Q2, amplified with the concussion frequency that oscillating circuit 22 is produced, be used for driving piezoelectric patches, it is shaken under the frequency of being desired.
In the circuit diagram of Fig. 3, when concussion transistor OSC1 was 5MHz, oscillating circuit 22 produced the concussion frequency of a 5MHz, after amplifying via power amplifier device 23, promptly can be used to drive piezoelectric patches, to make its concussion frequency be 5MHz, produce average grain diameter at the droplet of 1.0 μ m to carry out various application.Because when using the concussion frequency of higher 5MHz to produce the ultrasonic droplet, the spray amount that it produced is also used the ultrasonic atomizer of 1.6MHz or 2.4MHz relatively to reduce and is produced the phenomenon of spray amount deficiency, but in the present invention, shown in Figure 4 as 4, be to use a plurality of at least piezoelectric patches 25 to be arranged at this below, concussion liquid storaging device 24 bottoms, to improve the problem of atomizer spray quantity not sufficient when using 5MHz concussion frequency, can overcome the situation that the spray amount that produced this moment reduces.
By above explanation as can be known, the inferior micron of high-load of the present invention droplet ultrasonic atomizer really can produce the droplet of high-load time micron, overcomes the problem of the spray amount minimizing that is produced this moment simultaneously.
To sum up institute is old, and no matter the present invention all shows it be different from the feature of prior art with regard to purpose, means and effect, in fact is one to have the creation of practical value.
But above-mentioned many embodiment only be for convenience of explanation and for example, the rights protection that the present invention advocated should be as the criterion so that claim is described.
