Description

Technical Field

[0001] The present invention relates to the field of sprayer equipment, and in particular to an atomizing device and a handheld beauty instrument. Background Art

[0002] With the continuous improvement of modern living standards, people pay more and more attention to health and beauty. Atomizers with various functions are sold on the market to moisturize the skin, but most atomizers can only achieve moisturizing at room temperature. Or atomizers that can achieve hot spray moisturizing require the use of high-power heating devices (such as PTC heating sheets, heating tubes, etc.) to generate heat themselves to form a high-temperature surface. When water contacts the surface of the heating element, it quickly vaporizes under high temperature conditions to form steam. The volume expansion of the water during the vaporization process is used to spray the steam out of the pipe. The hot spray moisturizing atomizer is not portable because it requires high power to support the heating of the heating device. The principle that the heat of the high-temperature device vaporizes the liquid is not applicable to other essence liquids other than water, and the materials used are relatively limited.

[0029] like Figure 1-Figure 3As shown, the present invention discloses an atomizing device 10, which includes a fixing base 11, a ceramic atomizing sheet 12, a transition metal sheet 13, a first conductive structure 14 and a second conductive structure 15. The fixing base 11 includes a first through hole 114, a second through hole 115 and a mist outlet 111. The first through hole 114 and the second through hole 115 are both arranged on the first side wall of the fixing base 11, and the mist outlet 111 is arranged on the second side wall of the fixing base 11. The first side wall and the second side wall are opposite side walls; the ceramic atomizing sheet 12 is arranged in the fixing base 11 for forming a spray. The spray is sprayed out through the mist outlet 111; the transition metal sheet 13 is fitted on the first electrode 121 of the ceramic atomizing sheet 12 and protrudes from the ceramic atomizing sheet 12; one end of the first conductive structure 14 is in close contact with the transition metal sheet 13, and the other end passes through the first through-hole 114 to be electrically connected to the outside; one end of the second conductive structure 15 is in close contact with the second electrode 122 of the ceramic atomizing sheet 12, and the other end passes through the second through-hole 115 to be electrically connected to the outside, wherein the first electrode 121 and the second electrode 122 are respectively located on the two surfaces of the ceramic atomizing sheet 12. Specifically, the first electrode 121 is a positive electrode, and the second electrode 122 is a negative electrode. The first electrode 121 is arranged on the outer edge of the first surface of the ceramic atomizing sheet 12, and the second electrode 122 is arranged in the working area of ​​the second surface of the ceramic atomizing sheet 12, and the first surface and the second surface are opposite surfaces. The second conductive structure 15 includes a conductor 151 and a spring 152. One end of the conductor 151 passes through the second through hole 115 and is electrically connected to the outside. The spring 152 is pressed between the second electrode 122 and the conductor 151. The first conductive structure 14 and the conductor 151 are both conductive spring pins. The elasticity of the conductive spring pins and the elasticity of the spring 152 are used to ensure that the first conductive structure 14 and the second conductive structure 15 are always in contact with the positive and negative electrodes of the ceramic atomizer 12, respectively, to ensure that the circuit is in a conductive state and avoid poor power supply. The ceramic atomizer sheet 12 uses electronic high-frequency oscillation (the oscillation frequency is 1.7MHz or 2.4MHz, which exceeds the human hearing range and is harmless to humans and animals) to break up the liquid water molecular structure and produce naturally floating mist. Therefore, the mist particles are small and easily absorbed by the skin. Because the oscillation frequency of the ceramic atomizer sheet 12 is 1.7MHz or 2.4MHz, which is a constant oscillation frequency, naturally floating mist is evenly generated, and the ceramic atomizer sheet 12 generates a certain amount of heat during high-frequency oscillation, which can heat the mist.

[0030] Among them, the transition metal sheet 13 includes a first annular plate 132 and a first protrusion 131. The first annular plate 132 is attached to the first electrode 121, and the first protrusion 131 is arranged on the outer edge of the first annular plate 132. The first protrusion 131 is in close contact with one end of the first conductive structure 14. Since the part of the transition metal sheet 13 attached to the first electrode 121 is the first annular plate 132, and the first annular plate 132 has a hollow part, the contact area between the transition metal sheet 13 and the ceramic atomizer sheet 12 is reduced, thereby reducing the heat conduction area of ​​the transition metal sheet 13, avoiding too fast heat dissipation after large-area metal contact and affecting the temperature of the liquid after atomization. Therefore, the transition metal sheet 13 reduces the heat dissipation of the heat generated by the ceramic atomizer sheet 12 while realizing the conductive circuit.

[0031] In this embodiment, the fixing base 11 is configured as a detachable structure, and the fixing base 11 includes a first shell 110 and a second shell 113. The first shell 110 is detachably snapped onto the second shell 113 by snapping. The fixing base 11 is modularly designed to facilitate the assembly of the atomizing device 10. The first conductive structure 14 and the second conductive structure 15 are provided on the second shell 113, respectively corresponding to the first through hole 114 and the second through hole 115, so that the internal and external circuits of the atomizing device 10 are connected, and the circuit design is simplified; the ceramic atomizing sheet 12 and the transition metal sheet 13 are sequentially connected. It is fitted and fixed between the second shell 113 and the first shell 110, and a mist outlet 111 is provided on the first shell 110 corresponding to the atomization working area 123 of the ceramic atomization piece 12. The atomization device 10 also includes a liquid guide structure 17, which is fitted on the ceramic atomization piece 12. The liquid is guided into the atomization working area 123 of the ceramic atomization piece 12 through the liquid guide structure 17. The ceramic atomization piece 12 breaks up the water molecule structure in the liquid through high-frequency oscillation to generate spray, so that the particles of the spray are smaller and easily absorbed by the skin. The spray is sprayed out through the mist outlet 111. At the same time, the ceramic atomizing plate 12 generates heat during high-frequency oscillation, and the heat can heat the spray to achieve thermal spray. While ensuring that the transition metal plate 13 can achieve conductivity, the transition metal plate 13 is set to be hollow, and the contact area between the transition metal plate 13 and the ceramic atomizing plate 12 is minimized, thereby reducing the heat conduction area, so that the heat generated by the ceramic atomizing plate 12 is not quickly dissipated due to the excessively large contact area of ​​the transition metal plate 13, affecting the temperature of the liquid after atomization.

[0032] In one embodiment, the transition metal sheet 13 includes a first annular plate 132 and a first protrusion 131, the first annular plate 132 is fitted on the first electrode 121, the first protrusion 131 is arranged on the outer edge of the first annular plate 132, and the first protrusion 131 is in tight contact with one end of the first conductive structure 14; the second conductive structure 15 includes a conductor 151 and a spring 152, one end of the conductor 151 passes through the second through hole 115 and is electrically connected to the outside, and the spring 152 is pressed between the second electrode 122 and the conductor 151; the first conductive structure 14 is a conductive spring pin.

[0033] In this embodiment, the conductor 151 and the first conductive structure 14 are both conductive spring pins. Since the atomization working area 123 of the ceramic atomizing plate 12 vibrates at a high frequency and cannot be suppressed, the second conductive structure 15 is set to a conductor 151 and a spring 152. The conductor 151 can be a conductive spring pin. One end of the conductor 151 passes through the second through hole 115 and is electrically connected to the outside. The spring 152 is pressed between the second electrode 122 and the conductor 151. Since the spring 152 is elastic, it can always be pressed against the second electrode 122 and the conductor 151 to ensure that the circuit is in a conductive state, avoiding problems such as poor power supply and inability to use and charge. By connecting the first conductive structure 14 with the first protrusion 131 of the transition metal sheet 13, the first annular plate 132 of the transition metal sheet 13 is fitted on the first electrode 121 of the ceramic atomizer sheet 12, so that the first electrode 121 of the ceramic atomizer sheet 12 is connected to the external circuit through the transition metal sheet 13 and the first conductive structure 14. At the same time, because the part of the transition metal sheet 13 fitted on the first electrode 121 is the first annular plate 132, and the first annular plate 132 has a hollow part, the contact area between the transition metal sheet 13 and the ceramic atomizer sheet 12 is reduced, thereby reducing the heat conduction area of ​​the transition metal sheet 13, avoiding too fast heat dissipation after large-area metal contact and affecting the temperature of the liquid after atomization. Therefore, the transition metal sheet 13 reduces the heat dissipation of the heat generated by the ceramic atomizer sheet 12 while realizing the conductive circuit.

[0034] In one embodiment, the fixing base 11 includes a first shell 110 and a second shell 113, the first shell 110 is detachably arranged on the second shell 113, the first through hole 114 and the second through hole 115 are both arranged on the second shell 113, and the mist outlet 111 is arranged on the first shell 110.

[0035] In one embodiment, the fixing base 11 is configured to have a detachable structure, and the fixing base 11 includes a first shell 110 and a second shell 113. The first shell 110 is detachably snapped onto the second shell 113 by snapping. The fixing base 11 is modularly designed to facilitate assembly of the atomization device 10. The first conductive structure 14 and the second conductive structure 15 are provided on the second shell 113, respectively corresponding to the first through hole 114 and the second through hole 115, so that the internal and external circuits of the atomization device 10 are connected, and the circuit design is simplified; the ceramic atomization sheet 12 and the transition metal sheet 13 are sequentially fitted and fixed between the second shell 113 and the first shell 110, and a mist outlet hole 111 is provided on the first shell 110 corresponding to the atomization working area 123 of the ceramic atomization sheet 12, so that the spray can be ejected through the mist outlet hole 111.

[0036] In one embodiment, the second shell 113 has a third side wall 116, and the atomization device 10 also includes a buffer silicone pad 16, which includes a second protrusion 161 and a second annular plate 162, the second protrusion 161 is arranged on the outer edge of the second annular plate 162 and is located at the liquid inlet of the fixing seat 11, and the second annular plate 162 is fitted between the third side wall 116 and the ceramic atomization plate 12; the first shell 110 has a fourth side wall 112, and the fourth side wall 112 and the third side wall 116 are arranged in a coordinated and inclined manner, and the buffer silicone pad 16, the ceramic atomization plate 12 and the transition metal plate 13 are sequentially fitted and fixed between the third side wall 116 and the fourth side wall 112. In which, the first annular plate 132 has a notch 133, and the atomization device 10 also includes a liquid guide structure 17, which includes a fitting portion 172 and an extension portion 171. The fitting portion 172 is fitted on the working area of ​​the ceramic atomization plate 12 and embedded in the hollow portion of the adapter metal plate 13. The extension portion 171 extends outside the liquid inlet of the fixed seat 11 through the notch 133. The fitting portion 172 is provided with a third through hole 173, and the third through hole 173 is located in the area corresponding to the mist outlet hole 111, and is used to form a liquid film in the third through hole 173; the diameter of the third through hole 173 is 1.5mm-2.5mm.

[0037] Specifically, the material of the liquid-conducting structure 17 is non-woven fabric or absorbent cotton. Since non-woven fabric and absorbent cotton are absorbent, they are conducive to better forming a liquid film in the through hole; the mist outlet hole 111 is set to be a trumpet shape, and the small-diameter end of the mist outlet hole 111 is set inside the fixed seat 11, and the large-diameter end of the mist outlet hole 111 is set on the outer surface of the fixed seat 11, so that the spray is sprayed more evenly.

[0038] In this embodiment, the buffer silicone pad 16 is used to reduce the vibration of the ceramic atomizer piece 12 on the second shell 113, and the fourth side wall 112 and the third side wall 116 are matched and tilted, and the buffer silicone pad 16, the ceramic atomizer piece 12, the transition metal sheet 13 and the liquid guide structure 17 are sequentially fitted and fixed between the third side wall 116 and the fourth side wall 112, so that the buffer silicone pad 16, the ceramic atomizer piece 12, the transition metal sheet 13 and the liquid guide structure 17 are tilted in the fixing seat 11, and a third through hole 173 is provided on the fitting portion 172. The tilted setting of the liquid guide structure 17 is conducive to the protruding portion 171 of the liquid guide structure 17 to guide the liquid. The liquid is guided to the fitting portion 172, and the material of the liquid-guiding structure 17 is water-absorbent, which is conducive to better forming a liquid film in the third through hole 173. The third through hole 173 is located in the area corresponding to the mist outlet hole 111 and is also located in the atomization working area 123 of the ceramic atomization piece 12. Therefore, when the ceramic atomization piece 12 is working, the liquid water molecules of the liquid film in the third through hole 173 are broken up to generate spray, and the spray is ejected through the mist outlet hole 111. At the same time, the diameter of the third through hole 173 is set to 1.5mm-2.5mm. By limiting the diameter of the third through hole 173 and thus limiting the spraying amount, it is more conducive to the uniform spraying of the spray.

[0039] In this embodiment, the second protrusion 161 of the buffer silicone pad 16 is arranged on the outer edge of the second annular plate 162 and is located at the liquid inlet of the fixing seat 11. The second protrusion 161 not only reduces the vibration of the ceramic atomizing plate 12 on the second shell 113, but also supports the protruding portion 171 of the liquid guiding structure 17. Moreover, a surface of the second protrusion 161 used to support the protruding portion 171 is set to be inclined, so that the protruding portion 171 can guide the liquid to the fitting portion 172.

[0040] like Figure 4 As shown, an embodiment of the present invention further discloses a handheld beauty instrument 18, which includes the atomizing device 10. Specifically, the handheld beauty instrument 18 also includes a liquid storage box 181, a flow guide tube 182 and a third shell 183. The liquid storage box 181 is arranged on one end of the third shell 183, and the flow guide tube 182 and the atomizing device 10 are both arranged in the third shell 183. One end of the flow guide tube 182 is arranged on the liquid outlet of the liquid storage box 181, and the other end is arranged on the fixing seat 11. The flow guide tube 182 connects the liquid storage box 181 and the fixing seat 11, and the third shell 183 is provided with a mist outlet 184 that is connected to the mist outlet hole 111; the liquid can be a fluid such as water or essence.

[0041] In this embodiment, by pouring liquid into the liquid holding box 181, the liquid flows through the liquid outlet of the liquid holding box 181 and the guide tube 182 to reach the extension 171 of the liquid guide structure 17, and the extension 171 guides the liquid to the fitting portion 172 of the liquid guide structure 17, forming a liquid film in the third through hole 173. When the ceramic atomizer 12 is turned on, the ceramic atomizer 12 generates high-frequency oscillation to break up the liquid water molecular structure of the liquid film and generate self- The mist is naturally floating, so the particles of the mist are small and easily absorbed by the skin. At the same time, because the oscillation frequency of the ceramic atomizer 12 is 1.7MHz or 2.4MHz, which is a constant oscillation frequency, the spray is generated evenly, and the spray is evenly ejected through the mist outlet 111 and the mist outlet 184 in turn. The ceramic atomizer 12 generates a certain amount of heat during high-frequency oscillation, which can heat the spray, making the ejected spray a hot spray, which does not irritate the skin and improves the user experience.
