Description

Technical Field

[0001] The present invention relates to the technical field of portable microwave devices, and in particular to a portable microwave atomization device. Background Art

[0002] Atomization is a technology that disperses liquid into fine mist particles. There are many ways to achieve atomization, including pressure, vibration, and thermal energy. These methods break down the liquid into uniform small particles by increasing the flow rate on the surface of the liquid or destroying its surface tension. Traditional thermal atomization devices mainly rely on heating wire heating and magnetic induction heating. These methods heat the liquid by directly contacting a heating element to reach the temperature required for atomization. However, this heating method is prone to uneven heating. Local overheating not only affects the atomization effect of the liquid, but also may cause uneven particle size. For example, in medical scenarios, uneven distribution of drug particles will directly affect the absorption efficiency and reduce the treatment effect. In addition, the heating efficiency is low, and part of the energy is lost in the device itself, further increasing the energy consumption of the device operation. Not only that, the operating temperature of the atomizer is generally required to be between 35-50°C to ensure the atomization effect while avoiding adverse changes in the liquid. If the temperature is too high, some drugs may decompose, fail, or even produce white foam, significantly reducing the atomization efficiency.

[0003] Therefore, a portable microwave atomization device is proposed to solve the above problems. Summary of the invention

This design principle can be explained by the following formula:

[0013]

[0014] Among them, λ eff is the effective wavelength after filling the medium, λ0 is the wavelength in free space, ε r is the relative dielectric constant of the wave-transmitting material. By selecting a high dielectric constant material (ε r >1), which can significantly shorten the effective wavelength in the resonant cavity and thus reduce the operating frequency while maintaining the compactness of the device.

[0034] The microwave generator 9 is used to emit microwaves. The microwave shielding cover 2 absorbs and reflects microwave energy to improve energy utilization efficiency and reduce microwave radiation. The microwaves enter the cavity 7 through the coaxial line 8. The heat-insulating and wave-transmitting material in the cavity 7 facilitates the passage of microwaves. The microwaves then enter the second heating cavity 3. The heat-insulating and wave-transmitting material in the second heating cavity 3 insulates the first heating cavity 4 and the microwave shielding cover 2. The upper cover body and the lower cover body are connected by a threaded connection 5.

[0035] The coaxial line 8 is a microwave transmission device in the microwave field. Its structure is a hollow metal cylinder with a metal column placed at the axis. Microwaves propagate in the space between the hollow metal cylinder and the metal column.
