The invention provides an atomization device 10 which is applied to a mobile portable charging atomization aromatherapy machine 1000.

Referring to fig. 1 to 3, in an embodiment of the present invention, an atomizing device 10 includes: the water tank 11 is provided with an atomizing cavity 11a, the bottom of the water tank 11 is provided with a through hole 11b communicated with the atomizing cavity 11a, and the top of the water tank 11 is provided with a mist outlet 11c communicated with the atomizing cavity 11 a; and the atomizing sheet 12 is arranged at the bottom of the water tank 11, the atomizing sheet 12 is covered on the through hole 11b, and the surface of the atomizing sheet 12 facing the water tank 11 is concave.

Specifically, an atomization cavity 11a is formed inside the water tank 11, and the through hole 11b may be circular, is formed at the bottom of the water tank 11, penetrates through the water tank 11, and is communicated with the atomization cavity 11 a; the mist outlet 11c is arranged at the top of the water tank 11 and is also communicated with the atomizing cavity 11 a. The atomizing plate 12 is generally made of a piezoelectric ceramic body, and is mounted on the bottom of the water tank 11 to cover the through hole 11b, and the surface of the atomizing plate 12 facing the water tank 11 is concave. When atomizing, add water in the water tank 11, water flows to the atomizing piece 12 of bottom by through-hole 11b, and atomizing piece 12 produces the ultrasonic wave and atomizes water, and the steam after the atomizing flows out by atomizing chamber 11a and mist export 11c to adjust the humidity of outside air. Compared with the planar atomizing sheet 12, the ultrasonic atomizing device has the advantages that the concave atomizing sheet 12 is adopted, and the emitted ultrasonic waves are high-intensity focused ultrasonic waves, so that the energy of the ultrasonic waves is improved, the atomizing amount is larger, the atomizing efficiency is higher, the energy consumption is reduced, and the energy-saving effect is achieved.

It should be noted that, the frequency of the atomizing plate 12 is 2.4-3.3MHZ, and the power of 2W-5W is adopted for driving, the particle diameter of the particles atomized by the atomizing plate 12 can reach 3 μm, the atomizing effect is fine and smooth, the absorption by the user is facilitated, and the user experience effect is good.

Therefore, it can be understood that, in the technical solution of the present invention, the atomizing device 10 includes a water tank 11 and an atomizing sheet 12, the water tank 11 is provided with an atomizing cavity 11a, a through hole 11b communicated with the atomizing cavity 11a is formed at the bottom of the water tank, a mist outlet communicated with the atomizing cavity 11a is formed at the top of the water tank, the atomizing sheet 12 is installed at the bottom of the water tank 11 and covers the through hole 11b, and the surface of the atomizing sheet 12 facing the water tank 11 is concave. When the humidity of air is adjusted by adopting the atomization device 10, water is introduced into the water tank 11, the water flows to the atomization sheet 12 from the through hole 11b at the bottom of the water tank 11, the atomization sheet 12 generates ultrasonic waves to atomize the water, and atomized mist enters the atomization cavity 11a and then flows out from the mist outlet 11c at the top to enter the air to adjust the humidity. Because the concave atomizing sheet 12 is adopted in the invention, the emitted ultrasonic waves are high-intensity focused ultrasonic waves, so that the energy of the ultrasonic waves is improved, the atomizing amount is larger, the atomizing efficiency is higher, the energy consumption is favorably reduced, and the energy-saving effect is achieved.

Alternatively, referring to fig. 10 and 11, the atomizing plate 12 is a circular atomizing plate 12, and the surface of the atomizing plate 12 facing the water tank 11 is disposed in a concave spherical surface.

The atomizing sheet 12 is a circular atomizing sheet, and the surface of the atomizing sheet facing the water tank 11 is a concave spherical surface, so that the ultrasonic waves emitted by the atomizing sheet 12 are focused ultrasonic waves with higher intensity, the energy of the ultrasonic waves is effectively improved, the atomizing amount and the atomizing efficiency of the ultrasonic waves are further improved, and the energy-saving effect is effectively achieved.

The size of the circular atomizing plate 12 is suitably controlled for achieving the best atomizing efficiency. The radius of curvature of the atomizing plate 12 is defined as R, the diameter is defined as D, the thickness is defined as T, R is 2 times to 2.5 times the thickness of D, and T is 0.08 times to 0.15 times the thickness of D. The radius of curvature R, the diameter D and the thickness T of the circular atomizing plate 12 are in a proportional relationship, and the diameter of the atomizing plate 12 is usually 12mm to 20mm, for example, D is 12mm, 14mm, 16mm, 18mm or 20 mm.

When the atomization is performed, the atomization sheet 12 is electrically connected to the circuit board, the input current range of the atomization sheet 12 is 0.3A to 2A, and the input power range is 1.5W to 5W.

Referring to fig. 12, fig. 12 is a graph illustrating the comparison between the atomization efficiencies of the conventional planar atomization sheet 12 and the concave atomization sheet 12 of the present invention. As can be seen from the figure, the planar atomizing plate 12 with the conventional frequency of 3MHZ needs the input power of 2.5W or more to atomize the liquid, and when the input power is 3.5W or more, the maximum atomizing amount is 40ml/h or more when the liquid level is at the optimum resonance point. In contrast, the input current range of the concave atomizing plate 12 of the present invention is 0.3A to 2A, the input power range is 1.5W to 5W, the input current is usually set to 0.4A to 0.6A, and the input power is set to 2W to 3W, the maximum atomizing amount at the optimum resonance point of the liquid level is 20ml/h to 40ml/h, and thus it can be seen that the atomizing efficiency of the concave atomizing plate 12 of the present invention is improved by about 1 time or more than that of the planar atomizing plate 12.

As can be understood, referring to fig. 13, the energy transfer mode of the conventional 3MHz planar atomizing plate 06 is an ultrasonic field emitted in parallel, and it is usually necessary to add an energy gathering device (energy gathering nozzle 02) on the atomizing plate 01 to atomize the liquid, the energy gathering device is usually a narrow cavity, when water is added, bubbles are generated due to impact of water flow, when the liquid is heated, bubbles are generated and attached around the energy gathering device, and the bubbles seriously affect the cavitation efficiency of the ultrasonic wave, thereby affecting the atomization generation or even no atomization. The invention adopts the concave atomizing sheet which has the function of high-intensity focused ultrasonic waves, so that an energy gathering device (energy gathering nozzle 02) is not needed, and the atomizing efficiency is not influenced by bubbles.

It should be noted that, when the input current of the concave atomizing plate 12 of the present invention is increased to 0.8A to 1A and the input power is increased to 4W to 5W, the atomizing amount can be increased to more than 60 ml/h.

Further, the through hole 11b is a circular hole, and the diameter of the through hole 11b is smaller than the diameter of the concave spherical surface of the atomizing plate 12. The diameter of the through hole 11b is set to be smaller than the diameter of the concave spherical surface of the atomizing plate 12, so that the water in the water tank 11 can smoothly and effectively flow into the concave surface 25 of the atomizing plate 12 from the through hole 11b, the energy generated by the atomizing plate 12 of the concave surface 25 is transmitted through the liquid in an ultrasonic mode, and cavitation is generated on the liquid surface to tear liquid drops, thereby achieving the atomization effect.

Further, referring to fig. 3 to 5, the bottom of the water tank 11 is provided with a guide groove 1111, and the through hole 11b is opened at the bottom wall of the guide groove 1111. Here, the guide groove 1111 is formed in a substantially circular stepped groove shape, and a recess is formed in the bottom of the water tank 11, and the through hole 11b is opened in the bottom wall of the guide groove 1111, so that water in the water tank 11 can first flow into the guide groove 1111 and then flow from the through hole 11b in the bottom wall of the guide groove 1111 to the atomizing plate 12 for atomization. So can atomize more fully and effectively for the remaining water yield after the atomizing is less.

Referring to fig. 10 again, the atomizing plate 12 includes an atomizing plate body 121 and a connecting electrode 122, the surface of the atomizing plate body 121 facing the water tank 11 is concave, and the connecting electrode 122 is disposed around the outer side of the atomizing plate body 121 along the circumference of the atomizing plate body 121 for electrically connecting to the circuit board.

The atomizing sheet body 121 is made of ceramic, and is usually formed by sintering after being molded by a special mold, the outer contour of the atomizing sheet body 121 is circular and is a concave spherical surface, the connecting electrode 122 is generally a silver electrode, and the connecting electrode 122 is generally manufactured by spraying because the atomizing sheet body 121 is a concave spherical surface and has a certain curvature. It should be noted that an electronic wire is further soldered to the connecting electrode 122 for connecting to a driving circuit board to control the input voltage of the atomizing plate 13.

Further, the atomizing plate 12 further includes a protective layer (not shown), and the protective layer is disposed on a surface of the atomizing plate body 121 facing the water tank 11.

The protective layer can be a glaze protective layer, and is generally formed by spraying the protective layer on the concave surface 25 of the atomizing sheet body 121 in a spraying mode, drying, sintering and forming, and polarizing at high temperature after forming. The setting of inoxidizing coating has played better guard action to atomizing piece body 121 to avoid influencing the atomizing effect because of being destroyed.

Referring to fig. 3 to 5 again, a mounting ring 1113 is convexly disposed at the bottom of the water tank 11, and the through hole 11b is located in the mounting ring 1113; the atomization device 10 further comprises a mounting bracket 13 and a sealing ring 14, the mounting bracket 13 is fixedly connected to the bottom of the water tank 11 and encloses with the mounting ring 1113 to form a mounting space, the sealing ring 14 is arranged in the mounting space, and the atomization sheet 12 is arranged in the sealing ring 14.

Specifically, the mounting ring 1113 is disposed corresponding to the guide groove, and the through hole 11b is located in the mounting ring 1113. The mounting bracket 13 is fixedly connected to the bottom of the water tank 11 by screws and forms a mounting space with the mounting ring 1113, the sealing ring 14 is fixed in the mounting space, and the atomizing plate 12 is mounted in the sealing ring 14. The water in the water tank 11 first flows into the guide groove, then flows into the mounting ring 1113 through the through hole 11b, and flows toward the atomizing plate 12.

It can be understood that the sealing ring 14 is located between the atomizing plate 12 and the bottom bracket of the water tank 11, and can play a role of sealing, thereby effectively preventing water leakage during atomization.

Further, in order to improve the installation steadiness and the sealing performance of sealing washer 14, sealing washer 14 protruding is equipped with spacing muscle (not marking), and the part that the water tank 11 bottom is located the installation space has seted up draw-in groove (not marking) correspondingly, and spacing muscle joint is in the draw-in groove. Optionally, the limiting ribs are of annular structures, and the number of the limiting ribs can be two or three.

Referring to fig. 3 and 4, in an embodiment of the present invention, the atomizing device 10 further includes a water blocking member 15, and the water blocking member 15 is disposed in the atomizing chamber 11a and above the atomizing plate 12.

Because the atomizing sheet 12 can produce like fountain water column in the atomizing chamber 11a during ultrasonic atomization, set up water blocking member 15 here to play the effect of manger plate, lead the water column to the water tank 11 in effectively, produce the noise in order to reduce the water column nature falls into the water tank 11 during atomizing.

It can be understood that the mist generated by the operation of the atomizing plate 12 will preferentially adhere to the water-blocking member 15 after entering the atomizing area, so as to effectively avoid the situation that the inner wall of the atomizing chamber 11a adheres more water.

In an embodiment of the present invention, the bottom wall of the water tank 11 is convexly provided with a fixing column 1114, the water blocking member 15 includes a drainage column 151 and a water blocking sheet 152, the drainage column 151 is fixed to the fixing column 1114, the water blocking sheet 152 is disposed at an end of the drainage column 151 away from the fixing column 1114 and is located above the atomizing sheet 12, and the surface of the water blocking sheet 152 facing the atomizing sheet 12 is concave.

The protruding diapire of locating water tank 11 of fixed column 1114, fixed column 1114 can be that the diapire of grafting or joint water tank 11 is fixed, also can be with water tank 11 structure as an organic whole, here utilizes fixed column 1114 to fix water blocking piece 15, and the design is comparatively reasonable, and the structure is comparatively simplified. The drainage column 151 is fixed in the upper end of fixed column 1114, and the water blocking piece 152 is located in one side of the drainage column and above the atomizing piece 12, and the surface of the water blocking piece 152 facing the atomizing piece 12 is a concave surface 25. Thus, when the atomizing sheet 12 is used for ultrasonic atomization, the generated water column is sprayed to the inner concave surface of the water blocking sheet 152, flows to the edge of the water blocking sheet 152 along the inner concave surface, and then flows back to the water tank 11 along the flow guiding column 151, so that the noise generated when the water column falls into the water tank 11 during atomization can be effectively reduced.

Optionally, the concave surface of the water blocking sheet 152 is a concave arc surface to facilitate the water flow to smoothly flow to the edge thereof and flow back to the water tank 11 along the drainage column 151.

Optionally, the drainage column 151 and the fixed column 1114 are fixedly connected in an inserting manner, that is, an inserting groove (not marked) is formed in an end portion of the fixed column 1114, which is away from the bottom wall of the water tank 11, an inserting column (not marked) is formed at one end of the drainage column 151, and the inserting column is fixedly connected in the inserting groove in an inserting manner, so that the drainage column 151 and the fixed column 1114 can be fixedly connected. The insertion column may be a stepped column, and accordingly, the insertion groove is a stepped hole, and the sizes of the insertion groove and the stepped hole are matched, so that the fixation of the drainage column 151 and the fixing column 1114 can be enhanced. Of course, the insertion column may also be configured as a fool-proof structure, or the insertion column and the insertion groove may be fixed in an interference fit, which is within the protection scope of the present invention.

Further, referring to fig. 3, the plane of the outer edge of the water-blocking sheet 152 is inclined to define an included angle a between the plane of the outer edge of the water-blocking sheet 152 and the horizontal plane, where a is greater than or equal to 5 ° and less than or equal to 60 °. Here, the outer edge of the water blocking plate 152 is slightly inclined, so that the surface tension between the water and the water blocking plate 152 is greater than the gravity, and the water flows along the inclined edge to the drainage column 151 and finally flows back to the water tank 11.

In order to achieve a better water retaining effect, a concave spherical surface (not shown) is formed in the middle of the concave surface 25 of the water retaining sheet 152 facing the atomizing sheet 12, the distance between the deepest part of the concave spherical surface and the outer edge of the concave surface 25 of the water retaining sheet 152 ranges from 30mm to 120mm, and the diameter range of the concave spherical surface ranges from 15mm to 100 mm.
