Description

Technical Field

[0001] This invention relates to the field of atomization technology, and more particularly to an atomization device capable of atomizing oily or viscous liquids. Background Technology

[0002] Atomizing devices are devices that atomize liquids. For water or dilute drug solutions, existing atomizing devices typically use piezoelectric ceramic atomizing plates combined with electrical properties to achieve high-frequency oscillation for atomization. They also employ relatively large-diameter circular liquid outlets to ensure that the liquid flowing out of the circular outlet has a larger contact surface with the atomizing plate, thereby expanding the final atomized spray area. However, for highly viscous or oily liquids, such as essential oils, the high viscosity makes it difficult to atomize them using existing atomizing devices with piezoelectric ceramic atomizing plates. Therefore, existing atomizing devices for highly viscous or oily liquids typically employ a high-pressure air pump combined with a nozzle, or a two-fluid technology. Compared to existing atomizing devices with piezoelectric ceramic atomizing plates, these devices have the following problems: higher production costs, resulting in higher market prices and significantly increasing the burden on consumers; and because they all require air pumps, they generate considerable noise and are relatively large, making them inconvenient for consumers to use and store.

[0003] Therefore, it is necessary to provide an atomizing device that can atomize oily or viscous liquids with low production cost and small size. Summary of the Invention

[0004] The purpose of this invention is to provide an atomizing device for atomizing oily or viscous liquids that has low production cost and small size.

[0005] To achieve the above objectives, the present invention provides an atomizing device for atomizing oily or viscous liquids, comprising a liquid storage chamber, a flow guide, and an atomizing plate assembly. The liquid storage chamber has a storage space for storing oily or viscous liquids. The flow guide has a flow channel connected to the liquid storage chamber, with one end of the flow channel communicating with the storage space and the other end of the flow channel forming a liquid outlet hole on the flow guide. The atomizing plate assembly is disposed on the flow guide and includes an atomizing plate and a wrapping soft body. The wrapping soft body wraps around the atomizing plate and exposes the atomizing plate. The atomizing plate has an exposed metal area facing the liquid outlet hole, and the area of ​​the liquid outlet hole is smaller than the area of ​​the exposed metal area.

[0006] Preferably, the atomizing plate includes a vibrating metal plate and a piezoelectric ceramic ring. The piezoelectric ceramic ring is disposed on the vibrating metal plate. The area surrounded by the piezoelectric ceramic ring on the vibrating metal plate is the exposed metal area. A recessed area is provided in the exposed metal area. A microporous area is provided in the recessed area. The area of ​​the liquid outlet is smaller than the area of ​​the recessed area.

[0007] Preferably, the atomizing plate includes a vibrating metal plate and a piezoelectric ceramic ring, the piezoelectric ceramic ring is disposed on the vibrating metal plate, the area surrounded by the piezoelectric ceramic ring on the vibrating metal plate is the exposed metal area, the exposed metal area is provided with a microporous area, and the area of ​​the liquid outlet hole is smaller than the area of ​​the microporous area.

[0008] Preferably, the liquid outlet is circular in shape.

[0009] Preferably, the outlet hole has a sharp angle to disrupt the surface tension of the liquid.

[0010] Preferably, the liquid outlet is triangular, cross-shaped, elongated, or polygonal in shape.

[0011] Preferably, the guide member has a guide groove on the surface forming the liquid outlet hole, and the guide groove extends to the liquid outlet hole.

[0012] Preferably, the inner wall of the flow channel is provided with a first protrusion or depression structure for disrupting the surface tension of the liquid.

[0013] Preferably, the inner wall of the flow channel is provided with a second protrusion for limiting the flow rate.

[0014] Preferably, the second protrusion extends into the liquid storage space.

[0015] Preferably, the axis of the center point of the liquid outlet is different from the axis of the center point of the exposed metal area of ​​the atomizing plate.

[0016] Preferably, the flow guide has several third protrusions arranged around the liquid outlet on the surface forming the liquid outlet, the third protrusions being used to create a squeezing effect between the flow guide and the wrapping soft material.

[0017] Compared with the prior art, the atomizing device for atomizing oily or viscous liquids of the present invention sets the area of ​​the liquid outlet hole of the guide member to be smaller than the area of ​​the exposed metal area of ​​the atomizing plate facing the liquid outlet hole. This avoids the oily or viscous liquid flowing out of the liquid outlet hole from covering the exposed metal area of ​​the atomizing plate facing the liquid outlet hole, and reduces the pressure of the flowing oily or viscous liquid on the atomizing plate. This allows the atomizing plate to have enough space to vibrate the oily or viscous liquid, thereby breaking up and atomizing the oily or viscous liquid. Furthermore, since the atomizing device for atomizing oily or viscous liquids of the present invention adopts the structure of atomizing plate vibration atomization, it has the characteristics of low production cost and small size.

[0029] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please see Figures 1 to 3 The atomizing device 100 for atomizing oily or viscous liquids of the present invention includes a liquid storage chamber 1, a flow guide 2, and an atomizing plate assembly 3. The liquid storage chamber 1 has a storage space 11 for storing the oily or viscous liquid. The flow guide 2 has a flow channel 21 connected to the liquid storage chamber 1, with one end of the flow channel 21 communicating with the storage space 11 and the other end forming a liquid outlet hole 211 on the flow guide 2. The atomizing plate assembly 3 is disposed on the flow guide and includes an atomizing plate 31 and a wrapping soft body 32. The wrapping soft body 32 wraps around the atomizing plate 31 and exposes the atomizing plate 31. The atomizing plate 31 has an exposed metal area 311 facing the liquid outlet hole 211, and the area of ​​the liquid outlet hole 211 is smaller than the area of ​​the exposed metal area 311. Figure 3 As shown in the figure, S1 represents the area of ​​the liquid outlet 211, and S2 represents the area of ​​the exposed metal area 311, with S1 being smaller than S2. By setting the area of ​​the liquid outlet 211 of the guide member 2 to be smaller than the area of ​​the exposed metal area 311 of the atomizing plate 31 facing the liquid outlet 211, the oily or viscous liquid flowing out of the liquid outlet 211 is prevented from covering the exposed metal area 311 of the atomizing plate 31 facing the liquid outlet 211, and the pressure of the flowing oily or viscous liquid on the atomizing plate 31 is reduced. This allows the atomizing plate 31 to have enough space to vibrate the oily or viscous liquid, thereby breaking up and atomizing the oily or viscous liquid.

[0031] Please see Figure 4 and Figure 11 In one embodiment, the atomizing plate 31 includes a vibrating metal plate 314 and a piezoelectric ceramic ring 315. The piezoelectric ceramic ring 315 is disposed on the vibrating metal plate 314. The area surrounded by the piezoelectric ceramic ring 315 on the vibrating metal plate 314 is an exposed metal area 311. A recessed area 312 is provided within the exposed metal area 311, and a microporous area 313 is provided within the recessed area 312. The area of ​​the liquid outlet 211 is smaller than the area of ​​the recessed area 312. Figure 4As shown in the figure, S1 represents the area of ​​the liquid outlet 211, and S3 represents the area of ​​the recessed area 312, with S1 being smaller than S3. By setting the area of ​​the liquid outlet 211 to be smaller than the area of ​​the recessed area 312, the pressure exerted on the atomizing plate 31 by the oily or viscous liquid flowing out of the liquid outlet 211 is further reduced, as is the contact area between the oily or viscous liquid flowing out of the liquid outlet 211 and the atomizing plate 31. This further facilitates the atomizing plate 31 in breaking down and atomizing the oily or viscous liquid.

[0032] Please see Figure 5 and Figure 11 In one embodiment, the atomizing plate 31 includes a vibrating metal plate 314 and a piezoelectric ceramic ring 315. The piezoelectric ceramic ring 315 is disposed on the vibrating metal plate 314, and the area surrounded by the piezoelectric ceramic ring 315 on the vibrating metal plate 314 is an exposed metal area 311. The exposed metal area 311 is provided with a microporous area 313, and the area of ​​the liquid outlet 211 is smaller than the area of ​​the microporous area 313. Figure 5 As shown in the figure, S1 represents the area of ​​the liquid outlet 211, and S4 represents the area of ​​the microporous region 313, with S1 being smaller than S4. By setting the area of ​​the liquid outlet 211 to be smaller than the area of ​​the microporous region 313, the pressure exerted on the atomizing plate 31 by the oily or viscous liquid flowing out of the liquid outlet 211 is further reduced, as is the contact area between the oily or viscous liquid flowing out of the liquid outlet 211 and the atomizing plate 31, which is more conducive to the atomizing plate 31 breaking down and atomizing the oily or viscous liquid.

[0033] Please see Figure 6 In one embodiment, the liquid outlet 211 is circular in shape.

[0034] Please see Figure 7 and Figure 8 In one embodiment, the liquid outlet 211 has a sharp corner 211a to disrupt the surface tension of the liquid. Because the area of ​​the liquid outlet 211 of the guide member 2 is set to be at least smaller than the area of ​​the exposed metal region 311 of the atomizing plate 31 facing the liquid outlet 211, the liquid outlet 211 is relatively small. Although the pressure exerted on the atomizing plate 31 by the oily or viscous liquid flowing through the liquid outlet 211 is reduced, insufficient pressure may still cause the oily or viscous liquid to easily form surface tension at the location of the liquid outlet 211, preventing it from flowing out. Therefore, by setting the shape of the liquid outlet 211 to have a sharp corner 211a, the surface tension can be disrupted, allowing the oily or viscous liquid to flow out through the small-diameter liquid outlet 211. Specifically, the shape of the liquid outlet 211 can be triangular, cross-shaped, elongated, or polygonal. Figure 8 As shown, the liquid outlet 211 is cross-shaped. However, this is not a limitation; for example, as... Figure 7 As shown, the liquid outlet 211 is shaped like a five-pointed star.

[0035] Please see Figure 10 In one embodiment, the guide member 2 has a guide groove 22 on the surface forming the liquid outlet 211, and the guide groove 22 extends to the liquid outlet 211. By providing the guide groove 22, the surface tension formed at the liquid outlet 211 by the oily or viscous liquid flowing out through the liquid outlet 211 can be broken, thereby ensuring that the oily or viscous liquid can flow out through the small-diameter liquid outlet 211.

[0036] Please see Figure 9 In one embodiment, the inner wall of the flow channel 21 is provided with a first protrusion 23 for disrupting the surface tension of the liquid. By providing the first protrusion 23, the surface tension that may be formed by oily or viscous liquids in the flow channel 21 is disrupted, further ensuring that oily or viscous liquids can flow into the outlet hole 211 through the flow channel 21. However, this is not a limitation. For example, a recessed structure may also be provided on the inner wall of the flow channel 21 to disrupt the surface tension of the liquid.

[0037] Please see Figure 2 In one embodiment, a second protrusion 212 for limiting flow rate is provided on the inner wall of the flow channel 21. By limiting flow rate through the second protrusion 212, oily or viscous liquids are facilitated to form bubbles after being vibrated by the atomizing plate 31. These bubbles further reduce the pressure on the surface of the atomizing plate 31 of the atomizing plate assembly 3, thereby facilitating the atomization and spraying of oily or viscous liquids. Furthermore, the second protrusion 212 extends into the liquid storage space 11, so that the second protrusion 212 not only serves to limit flow rate but also to guide flow.

[0038] Please see Figure 5 In one embodiment, the axis of the center point of the liquid outlet 211 is different from the axis of the center point of the exposed metal area 311 of the atomizing plate 31. Figure 5 In the diagram, L1 represents the axis where the center point of the liquid outlet 211 is located, and L2 represents the axis where the center point of the exposed metal area 311 of the atomizing plate 31 is located. L1 and L2 are different and are not on the same straight line. That is to say, the axis L1 where the center point of the liquid outlet 211 is located is offset from the axis L2 where the center point of the exposed metal area 311 of the atomizing plate 31 is located, which can further reduce the pressure of the oily or viscous liquid flowing out of the liquid outlet 211 on the atomizing plate 31.

[0039] Please see Figure 9 and Figure 10 In one embodiment, the flow guide 2 has several rings of third protrusions 24 arranged around the liquid outlet 211 on the surface of the flow guide 2. The third protrusions 24 are used to create a squeezing effect between the flow guide 2 and the wrapping soft body 32, thereby preventing leakage.

[0040] Please see Figure 1 and Figure 2 The atomizing device 100 for atomizing oily or viscous liquids of the present invention further includes a housing 5, a circuit board 6, and a spray connector 4. The housing 5 has an accommodating space, and the liquid storage tank, the flow guide, the atomizing plate 31, the spray connector 4, and the circuit board 6 are all disposed within the accommodating space. The circuit board 6 is electrically connected to the atomizing plate 31. The spray connector 4 is connected to the flow guide, and the atomizing plate 31 is located between the spray connector 4 and the flow guide. The spray connector 4 is provided with a spray port communicating with the atomizing plate 31.

[0041] In summary, the atomizing device 100 for atomizing oily or viscous liquids of the present invention, by setting the area of ​​the liquid outlet hole 211 of the guide member 2 to be smaller than the area of ​​the exposed metal area 311 of the atomizing plate 31 facing the liquid outlet hole 211, avoids the oily or viscous liquid flowing out through the liquid outlet hole 211 from covering the exposed metal area 311 of the atomizing plate 31 facing the liquid outlet hole 211, and reduces the pressure of the flowing oily or viscous liquid on the atomizing plate 31, so that the atomizing plate 31 has enough space to vibrate the oily or viscous liquid, thereby breaking up and atomizing the oily or viscous liquid. Moreover, since the atomizing device 100 for atomizing oily or viscous liquids of the present invention adopts the structure of atomizing the atomizing plate 31 through vibration, it has the characteristics of low production cost and small size. The atomizing device 100 of the present invention, which can atomize oily or viscous liquids, can be configured by setting the shape of the liquid outlet 211 to have a sharp corner 211a. The sharp corner 211a can be used to break the surface tension so that the oily or viscous liquid can flow out of the small-diameter liquid outlet 211.

[0042] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
