Description

Technical Field

[0001] This invention relates to air conditioning and purification, and mainly to a high-frequency ultrasonic atomizer. Background Technology

[0002] Ultrasonic atomizers for air disinfection are suitable for use in various places such as public places, hospitals or factories. However, existing ultrasonic atomizers use high air pressure to discharge water mist when working, which makes the structure complex and the disinfection effect poor. Summary of the Invention

[0003] The purpose of this invention is to provide a high-frequency ultrasonic atomizer with good disinfection effect.

[0004] The high-frequency ultrasonic atomizer of the present invention includes a housing. Inside the housing, from top to bottom, are a vaporization chamber and a water tank. A steam outlet is provided on the front side plate of the vaporization chamber. The vaporization chamber is connected to the water tank. An ultrasonic atomizer is installed inside the water tank. A horizontally arranged "T"-shaped central partition is provided inside the vaporization chamber. Elongated through holes are provided on the left, right, and rear sides of the central partition. A vertical side plate facing the steam outlet and an inclined side plate connected to the vertical side plate are provided inside the vaporization chamber. The vertical and inclined side plates divide the space inside the vaporization chamber into a positive pressure air chamber. A fan is provided on the side wall of the positive pressure air chamber. The air outlets of the positive pressure air chamber are respectively located on the left side of the vertical side plate. The right side and the left and right sides of the inclined side plate allow air to be blown from the left and right sides towards the steam outlet and towards the central partition. The steam outlet of the vaporization box is located at the top of the front side wall of the vaporization box. A guide baffle is provided at the top of the vaporization box. The guide baffle includes a first inclined plate and a second inclined plate. One end of the first inclined plate is connected to the top of the positive pressure air chamber, and one end of the second inclined plate is connected to the top of the vaporization box. The other ends of the first inclined plate and the second inclined plate are both inclined downwards. The other end of the first inclined plate is connected to the other end of the second inclined plate to form a downward protrusion, so as to guide the water mist blown by the fan in the positive pressure air chamber to the steam outlet of the vaporization box.

[0005] In the high-frequency ultrasonic atomizer of the present invention, the second inclined plate forms an angle of less than 60 degrees with the vertical direction to prevent the rising airflow from flowing back into the vaporization chamber.

[0006] The high-frequency ultrasonic atomizer of the present invention further includes a lower water tank disposed below an upper water tank. The upper water tank and the lower water tank are connected by a water level drain pipe, which is vertically disposed at the bottom of the upper water tank. A water pump is disposed below the upper water tank, and the water pump is connected to the upper water tank and the lower water tank respectively through pipelines.

[0007] In the high-frequency ultrasonic atomizer of the present invention, gaps are left between the upper water tank, the lower water tank, the vaporization box and the front panel of the outer shell, and a blower is provided below the lower water tank. The blower is used to blow air through the gaps to the steam outlet of the vaporization box to form an air curtain.

[0008] In the high-frequency ultrasonic atomizer of the present invention, an electrical compartment is provided between the rear panel of the outer shell and the upper water tank for housing a power supply and a control board. Waterproof pressure strips are provided on the upper part and both sides of the front partition of the electrical compartment, and the power supply and control board are located on the inner side of the front partition.

[0009] In the high-frequency ultrasonic atomizer of the present invention, a water injection pipe is provided above the electrical chamber, one end of the water injection pipe extends into the lower water tank, and the other end of the water injection pipe is connected to the water receiving tray on the top of the outer shell.

[0010] The high-frequency ultrasonic atomizer of the present invention can effectively make the fine water mist particles preferentially discharged from the steam outlet and dispersed in the external environment, thereby improving work efficiency and enhancing disinfection effect.

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the high-frequency ultrasonic atomizer of the present invention includes a housing 1, and a vaporization box 2 and an upper water tank 3 are arranged from top to bottom inside the housing. A steam outlet 7 is provided on the front side plate of the vaporization box. The vaporization box is connected to the upper water tank, and an ultrasonic atomizer 4 is arranged inside the upper water tank.

[0016] Figure 3 This is a three-dimensional half-sectional view of the high-frequency ultrasonic atomizer of the present invention, showing half of the structure of the internal components of the housing.

[0017] The vaporization chamber is provided with a horizontally arranged "T"-shaped central partition 30, and the left, right and rear sides of the central partition 30 are respectively provided with elongated through holes 31.

[0018] The vaporization chamber is provided with a vertical side plate 41 facing the steam outlet and an inclined side plate 42 connected to the vertical side plate. The vertical side plate 41 and the inclined side plate 42 divide the space inside the vaporization chamber into a positive pressure air chamber 5. A fan 6 is provided on the side wall of the positive pressure air chamber. The air outlets 51 of the positive pressure air chamber are respectively provided on the left and right sides of the vertical side plate and the left and right sides of the inclined side plate to blow air from the left and right sides to the steam outlet and from the left and right sides to the central partition.

[0019] The vapor outlet of the vaporization chamber is located at the top of the front side wall of the vaporization chamber.

[0020] There are gaps between the upper water tank, the vaporization box and the front panel of the outer shell. A blower 8 is provided below the upper water tank. The blower is used to blow air through the gap to the steam outlet of the vaporization box to form an air curtain to guide the water mist upward.

[0021] The main function of the central baffle 30 is to "limit" the "fog surface height" after fogging. The left, right and rear sides of the central baffle 30 are respectively provided with long through holes 31, so that the positive pressure air chamber blows air down the central baffle, disturbing and activating the water mist molecules after fogging. The holes on both sides allow a large number of lighter water mist molecules to be squeezed to the top of the central baffle.

[0022] The air inlet of the positive pressure air chamber blows air from the left and right sides toward the steam outlet and from the left and right sides toward the central partition below, disturbing the water mist under the central partition and blowing up the disturbed, lighter water mist, and then blowing the mist out from the left and right sides toward the steam outlet.

[0023] In the high-frequency ultrasonic atomizer of the present invention, a flow guide baffle 20 is provided on the top of the vaporization chamber. The flow guide baffle includes a first inclined plate 21 and a second inclined plate 22. One end of the first inclined plate is connected to the top of the positive pressure air chamber, and one end of the second inclined plate is connected to the top of the vaporization chamber. The other ends of the first and second inclined plates are both inclined downwards. The other end of the first inclined plate is connected to the other end of the second inclined plate to form a downward protrusion, so as to guide the water mist blown by the fan in the positive pressure air chamber to the steam outlet of the vaporization chamber.

[0024] In the high-frequency ultrasonic atomizer of the present invention, the second inclined plate 22 forms an angle of less than 60 degrees with the vertical direction to prevent the rising airflow from flowing back into the vaporization chamber.

[0025] The high-frequency ultrasonic atomizer of the present invention further includes a lower water tank 9 disposed below an upper water tank. The upper water tank and the lower water tank are connected by a water level drain pipe 10, which is vertically disposed at the bottom of the upper water tank. A water pump 11 is disposed below the upper water tank, and the water pump is connected to the upper water tank and the lower water tank respectively through pipelines. The water pump 11 is used to pump water into the upper water tank.

[0026] In the high-frequency ultrasonic atomizer of the present invention, gaps are left between the upper water tank, the lower water tank, the vaporization box and the front panel of the outer shell. A blower 8 is provided below the lower water tank. The blower is used to blow air through the gaps to the steam outlet of the vaporization box to form an air curtain.

[0027] In the high-frequency ultrasonic atomizer of the present invention, an electrical compartment 12 is provided between the rear panel of the outer shell and the upper water tank for housing a power supply and a control board. Waterproof strips are provided on the upper part and both sides of the front partition 13 of the electrical compartment. The power supply and control board are located inside the front partition. A gap is left between the bottom surface of the electrical compartment 12 and the bottom surface of the outer shell, meaning the electrical compartment 12 is suspended.

[0028] When the high-frequency ultrasonic atomizer of the present invention tilts to the sides or backwards, the liquid in the vaporization box and the upper water tank overflows backwards, and the overflow will not easily flow into the electrical chamber; when a large amount of liquid seeps in, the liquid will not come into contact with it because the power supply and control board are suspended in the air (the power supply and control board do not contact the bottom surface of the electrical chamber).

[0029] In the high-frequency ultrasonic atomizer of the present invention, a water injection pipe 15 is provided above the electrical chamber, one end of the water injection pipe extends into the lower water tank, and the other end of the water injection pipe is connected to the water receiving tray 16 on the top of the outer shell.

[0030] When the high-frequency ultrasonic atomizer of the present invention is working, after the disinfectant water is atomized into water mist, the high-frequency ultrasonic atomizer of the present invention can effectively make the fine particulate water mist preferentially discharged from the steam outlet and dispersed in the external environment, thereby improving working efficiency and enhancing disinfection effect.

[0031] The vaporization chamber uses the principle of fractionation to separate water mist molecules into layers according to their size, with larger water mist molecules remaining at the bottom of the chamber and smaller water mist molecules near the top being carried out by a gentle breeze.

[0032] The second inclined plate 22 forms an angle of less than 60 degrees with the vertical direction so that the generated water mist has a certain angle of elevation when leaving the vaporization box. This angle of elevation is less than 60 degrees with the direction of the rising guide airflow, so as to prevent the wind of the rising guide airflow from flowing back into the vaporization box.

[0033] The vertical side plate 41 and the slanted side plate 42 serve to prevent water mist from directly contacting the fan and allow the air entering the vaporization chamber to enter from both sides. When the water mist carrying tiny molecules leaves the vaporization chamber, it will be concentrated and blown out towards the center. This allows the mist to exit from both sides of the vaporization chamber window without condensation, and it allows the water mist to concentrate in the center and be blown further.

[0034] A silent blower is built into the bottom of the casing, which generates an upward guiding airflow from inside the casing to outside the vaporization chamber.

[0035] The aforementioned vaporization chamber produces only a tiny water mist, which is extremely lightweight. The upward guiding airflow requires only a slight breeze to efficiently and quickly disperse this tiny water mist throughout the environment. This upward guiding airflow, positioned close to the narrow gap between the vaporization chamber and the outer shell, creates an airflow wall at the lower edge of the vaporization chamber, effectively preventing condensation from forming there.

[0036] A water level drain pipe is installed between the upper and lower water tanks. This water level drain pipe can ensure that the water level around the ultrasonic atomizer 4 does not become too high in the simplest and energy-saving way.

[0037] The water pump replenishes water at regular intervals during machine operation. Thanks to the drain pipe, the water level in the upper tank will not be too high. An excessively high water level would cause the ultrasonic water mist to attenuate.

[0038] The water pump is positioned below the lower water tank, effectively preventing the pump from running dry or being damaged when the lower water tank is emptied.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
