Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to an atomizer. Background Technology

[0002] Existing ultrasonic atomization technology typically converts liquid into mist through the high-frequency vibration of an atomizing plate, such as in household humidifiers and landscape atomizers. Current atomizers with frequencies around 108kHz use a water-absorbing rod for liquid supply, which often results in a small mist output due to the small contact area. To achieve a larger mist output, the vibration frequency of the atomizing plate needs to be increased, but high-frequency atomization devices are expensive, making equipment with a large atomization volume very costly.

[0003] Therefore, to solve the above-mentioned technical problems, a new technical solution is needed, specifically, an atomizer. Summary of the Invention

[0004] This invention provides an atomizer to solve the technical problem of low mist output in existing atomizers.

[0005] To achieve the above objectives, the following technical solution is provided: an atomizer, comprising a liquid storage device, a secondary liquid supply device, and an ultrasonic atomizing device, characterized in that: the secondary liquid supply device is disposed on the liquid storage device, the liquid storage device is provided with a water pump, the water pump inlet is connected to the bottom of the liquid storage device, and the water pump outlet is connected to the secondary liquid supply device; the ultrasonic atomizing device comprises an atomizing plate.

[0006] The secondary liquid supply device has a reflux gap at its edge, through which un-atomized liquid flows back into the liquid storage device. The secondary liquid supply device has an installation groove, and an atomizing plate is installed in the installation groove. The atomizing plate is in contact with the water-absorbing material below, and the water-absorbing material is in communication with the interior of the secondary liquid supply device.

[0007] Preferably, the secondary liquid supply device includes an atomizing cover and a liquid supply cover disposed below the atomizing cover. The liquid supply cover has a receiving cavity, which is connected to a liquid supply port. The atomizing cover has an installation groove, and a reflux gap is provided between the atomizing cover and the liquid supply cover, or the liquid supply cover has a reflux gap.

[0008] Preferably, the mounting groove of the atomizing cover is provided with a limiting step, and a receiving hole is provided below the limiting step. The receiving hole communicates with the receiving cavity, the water-absorbing material is disposed in the receiving hole, and the atomizing plate is disposed on the limiting step and in contact with the water-absorbing material.

[0009] Preferably, the receiving hole is a through hole or a blind hole, and when the receiving hole is a through hole, it communicates with the receiving cavity.

[0010] Preferably, the edge of the receiving hole is provided with a channel, and the channel communicates with the receiving cavity.

[0011] Preferably, the atomizing cover is further provided with an upper cover, the upper cover having mist outlet holes, the position and number of which correspond to the mounting groove.

[0012] Preferably, the liquid storage device includes a box body, and the box body is provided with a liquid storage chamber.

[0013] Preferably, a windproof cover is also provided above the upper cover, and the fog outlet is located inside the windproof cover; Beneficial effects

[0014] This invention adds a secondary liquid supply device and uses a water pump to provide atomizing liquid to the secondary liquid supply device, ensuring a sufficient supply of atomizing liquid below the atomizing plate. This allows the atomizing plate to effectively generate mist with each vibration, thereby increasing the atomization volume of the atomizer without the need for a high-frequency atomizing plate and reducing the production cost of high-atomization atomizers. Simultaneously, the secondary liquid supply device is equipped with a reflux gap. When there is excessive un-atomized liquid supplied by the water pump, the un-atomized liquid in the secondary liquid supply device flows back to the storage chamber through the reflux gap, creating a continuous circulation.

[0015] The atomizing fluid supplied to the atomizing plate via a water pump and a secondary liquid supply device is designed to prevent the fluid, which has low flowability, from clogging the supply channels when impurities are present. Existing atomizing fluids, such as disinfectants used in hospitals, often contain high-molecular-weight moisturizing ingredients to address dryness caused by the removal of excess oil from the skin during disinfection. In such cases, traditional supply methods can easily lead to insufficient supply and blockage of the supply channels. Furthermore, some disinfectants contain organic solvents that can cause swelling of existing absorbent swabs, also resulting in poor absorption. However, this invention, with its combination of a water pump and a secondary liquid supply device, avoids these problems of poor flowability and inadequate supply. The change in the composition of the atomizing fluid does not affect the supply volume, and therefore, does not affect the final atomization output of the product. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1 to 6 As shown, an atomizer includes a liquid storage device, a secondary liquid supply device, and an ultrasonic atomizing device. The secondary liquid supply device is mounted on the liquid storage device, and the ultrasonic atomizing device includes an atomizing plate. A water pump is installed inside the liquid storage device. The water pump inlet is connected to the interior of the liquid storage device, and the water pump outlet is connected to the secondary liquid supply device. The water pump outlet is connected to the liquid supply port below the secondary liquid supply device via a water pipe. A reflux gap 8 is provided at the edge of the secondary liquid supply device, through which the atomized liquid in the secondary liquid supply device flows back to the liquid storage device. An installation groove 21 is provided on the secondary liquid supply device, and an atomizing plate 5 is installed within the installation groove 21. The atomizing plate 5 is in contact with an absorbent material 6 below, and the absorbent material 6 is connected to the interior of the secondary liquid supply device. The absorbent material can be a soft, flocculent absorbent material such as absorbent cotton.

[0028] The storage device contains atomizing liquid. A water pump draws the atomizing liquid into a secondary liquid supply device. The absorbent material conducts the atomizing liquid in the secondary liquid supply device to the area below the atomizing plate. The high-frequency vibration of the atomizing plate converts the atomizing liquid in the absorbent material into mist.

[0029] like Figure 2 and Figure 3 As shown, the secondary liquid supply device includes an atomizing cover 2 and a supply cover 3 located below the atomizing cover 2. The supply cover 3 has a receiving cavity 31 for holding the atomized liquid pumped up by the water pump. The receiving cavity 31 is connected to a supply port 7. The atomized liquid in the storage device is pumped into the supply port by the water pump and stored again in the receiving cavity 31. The surface of the atomizing cover 2 has a downwardly recessed mounting groove 21, and a reflux gap 8 is provided between the atomizing cover 2 and the supply cover 3, or the supply cover 3 has a reflux gap 8. Figures 4 to 6 As shown, the reflux gap is used to return excess atomized liquid from the receiving cavity to the storage device. The location of the reflux gap can be replaced with other equivalent options. For example... Figure 3As shown, the mounting groove 21 of the atomizing cover 2 is provided with a limiting step 211, and a receiving hole 212 is provided below the limiting step 211. The receiving hole 212 communicates with the receiving cavity 31. The water-absorbing material 6 is disposed in the receiving hole 212, and the atomizing plate 5 is disposed on the limiting step 211 and contacts the top of the water-absorbing material 6. The receiving hole 212 is a through hole or a blind hole. When the receiving hole 212 is a through hole, it communicates with the receiving cavity 31. A channel 213 is provided on the edge of the receiving hole 212, and the channel 213 communicates with the receiving cavity 31. In this embodiment, the receiving hole 212 is preferably a through hole.

[0030] like Figure 2 As shown, the atomizing cover 2 is also provided with an upper cover 1, and the upper cover 1 is provided with mist outlet holes 11. The position and number of the mist outlet holes 11 correspond to those of the mounting groove 21. Multiple mist outlet holes can be set; the specific number is not limited. In this embodiment, eight are set. The liquid storage device includes a box body 4, and the box body 4 is provided with a liquid storage chamber 41 for holding the atomizing liquid. Figure 1 As shown, a windproof cover 9 is also provided above the secondary liquid supply device, and the mist outlet 11 is located inside the windproof cover 9. The windproof cover is detachably connected to the top cover 1 and is used to collect mist during hand sanitizing to improve the sterilization effect.

[0031] This invention provides an effective liquid supply system that avoids insufficient supply due to obstructed flow caused by changes in the composition of the atomizing liquid. It ensures that each vibration of the atomizing plate is effective and generates mist, thereby increasing the atomization volume. Devices producing the same mist output do not require high-frequency atomizing plates, reducing manufacturing costs and expanding the application range of atomizers. The atomizing device of this invention uses a commercially available ultrasonic atomizing device. This atomizer can be used in hand sanitizing, indoor air disinfection, and indoor humidification applications.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
