[0030] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1 , Figure 2 As shown, this embodiment provides a composite ceramic heating sheet, including a ceramic heating sheet 11 and a titanium copper layer 12, wherein the ceramic heating sheet 11 has a heating surface 111, and the titanium copper layer 12 is attached to the heating surface 111 of the ceramic heating sheet 11 by a spraying process (the spraying process is an existing spraying process). The composite ceramic heating sheet can achieve a good noise reduction effect when heated and atomized, and generates lower noise, which is more suitable for environments that require quietness, such as bedrooms.

[0033] Preferably, the thickness of the titanium copper layer 12 is 15 μm-25 μm, and its gram weight is less than 1 g / mm 2 , which can achieve good noise reduction without affecting the heating atomization of the ceramic heating plate 11.

[0034] Specifically, the titanium copper layer 12 is attached to the heating surface of the ceramic heating plate 11 by the existing spraying process, and has uniform thickness, mature preparation and high efficiency. Of course, in other embodiments, the titanium copper layer 12 can also be prepared by printing, coating and other methods in the existing technology, which can also achieve a good noise reduction effect.

[0035] Continue to refer to Figures 3 to 13 As shown, this embodiment also provides an atomizer, including a shell, an electronic system 30 and a receiving tank body 100 arranged in the shell; the bottom of the receiving tank body 100 is composed of an atomizing sheet, and the atomizing sheet 10 is a ceramic heating sheet of the composite material described above, and the titanium-copper layer 12 of the atomizing sheet 10 is located on the bottom surface of the receiving tank body 100; the electronic system 30 is electrically connected to the ceramic heating sheet 11 of the atomizing sheet 10 to control the heating of the ceramic heating sheet 11.

[0036] When in use, the container body 100 is used to contain the liquid to be atomized, and the electronic system 30 controls the ceramic heating plate 11 to heat, and the heating surface 111 of the ceramic heating plate 11 forms thermal contact with the liquid to heat and atomize the liquid. The titanium copper layer 12 effectively reduces the noise caused by the heating and atomization of the ceramic heating plate 11, and the noise generated is lower, which is more suitable for environments that require quietness, such as bedrooms.

[0037] Specifically, the specific structure of the electronic system 30, the connection method with the ceramic heating plate 11, and the working principle of controlling the heating of the ceramic heating plate 11 are all existing technologies, which have been mastered and applied by technicians in this field long ago, and will not be described in detail here.

[0038] Furthermore, in the present embodiment, the accommodating tank body 100 specifically includes: a cylindrical tank wall 14, a mounting ring 13 and the atomizing sheet 10, the inner ring wall surface of the mounting ring 13 is recessed with a limiting groove 131, the atomizing sheet 10 is assembled in the limiting groove 131 of the mounting ring 13, and forms a sealing fit with the mounting ring 13. The titanium copper layer 12 of the atomizing sheet 10 is located in the center hole of the mounting ring 13 and is arranged upward, and the lower open end of the cylindrical tank wall 14 is sealed to the upper surface of the mounting ring 13. The cylindrical tank wall 14, the mounting ring 13 and the atomizing sheet 10 are enclosed together to form a tank body for accommodating liquid. The accommodating tank body 100 adopts a combined assembly structure, and the atomizing sheet 10 can be prepared separately, which is convenient for preparation.

[0039] Furthermore, in the present embodiment, an annular groove 132 is recessed on the upper surface of the mounting ring 13, and the outer groove wall of the annular groove 132 is an arc-shaped groove wall. The lower open end of the cylindrical groove wall 14 has an arc-shaped section 141 extending inwardly, and the arc-shaped section 141 of the lower open end of the cylindrical groove wall 14 is sealed and abuts against the annular groove 132 on the upper surface of the mounting ring 13, and the upper surface of the arc-shaped section 141 is flush with the upper surface of the mounting ring 13; thereby, a smooth arc-shaped transition is formed between the groove bottom surface and the groove side wall surface of the accommodating groove body 100, which facilitates cleaning of the transition area and maintains cleanliness.

[0040] To be more specific, in the present embodiment, the middle portion of the ceramic heating plate 11 of the atomizing plate 10 has a boss 112 protruding upward and matching with the center hole of the mounting ring 13, the boss surface of the boss 112 is flush with the upper surface of the mounting ring 13, and the titanium-copper layer 12 is attached to the boss surface of the ceramic heating plate 11, that is, the boss surface is the heating surface 111 (the thickness of the titanium-copper layer 12 can be directly ignored), thereby making the bottom surface of the accommodating tank body 100 a plane, which facilitates cleaning of the bottom surface of the accommodating tank body 100 and maintains cleanliness.

[0041] Furthermore, in this embodiment, the materials of the cylindrical groove wall 14 and the mounting ring 13 are both heat-conducting materials, such as metal materials. The heat generated by the ceramic heating plate 11 can be transferred to the cylindrical groove wall 14 through the mounting ring 13, and then transferred from the cylindrical groove wall 14 to the liquid. In this way, the heat received by the liquid is more uniform, the overall temperature is higher, it is easier to be atomized, and the effect is better.

[0042] Of course, in other embodiments, the structure of the receiving tank 100 is not limited thereto.

[0043] Furthermore, in this embodiment, the housing includes a lower housing 21, a base 22 and a fixing plate 23, the lower housing 21 has an upper opening and a lower opening, the base 22 covers the lower opening of the lower housing 21, the fixing plate 23 is fixed in the lower housing 21, and the lower housing 21 is divided into an upper chamber 202 and a lower chamber 201, the accommodating tank 100 is arranged in the upper chamber 202, the electronic system 30 is arranged in the lower chamber 201, and a through hole 232 is opened on the fixing plate 23, and the electrode 31 of the electronic system 30 passes through the through hole 232 of the fixing plate 23 and is connected to the ceramic heating plate 11 of the atomizing plate 10. The heating atomizing structure and the electrical structure are isolated from each other and will not affect each other.

[0044] More specifically, the fixing plate 23 has a clearance groove 231, and the through hole 232 of the fixing plate 23 is opened at the bottom of the clearance groove 231. The bottom surface of the mounting ring 13 of the accommodating tank body 100 abuts against the fixing plate 23, and the atomizing sheet 10 is located above the clearance groove 231. The electrode 31 of the electronic system 30 is fixed in the clearance groove 231, which plays a role of fixed support and makes the structure more stable.

[0045] The inner wall of the lower shell 21 also extends with a limiting convex rib 211 and an abutting convex rib 212. The outer edge of the fixing plate 23 is protruded with a convex ring 233 corresponding to the outer side wall of the mounting ring 13. The limiting convex rib 211 is inserted between the convex ring 233 of the fixing plate 23 and the outer side wall of the mounting ring 13 to limit the position of the accommodating tank 100. The abutting convex rib 212 is fixedly abutted against the upper surface of the mounting ring 13, thereby abutting and fixing the mounting ring 13. More specifically, the upper surface of the mounting ring 13 is provided with a limiting convex ring 133 protruding from the periphery of the annular groove 132, and the abutting convex rib 212 abuts against the periphery of the limiting convex ring 133. The setting of the limiting convex ring 133, on the one hand, extends the sealing contact area with the cylindrical groove wall 14, so that the assembly stability of the cylindrical groove wall 14 and the mounting ring 13 is better, and on the other hand, the cooperation with the abutting convex rib 212 also plays a limiting role, so that the assembly of the accommodating groove body 100 is more precise.

[0046] The upper opening of the lower shell 21 also extends downward with an abutment ring 213, which seals and abuts against the upper opening end of the cylindrical groove wall 14, fixes the cylindrical groove wall 14, and seals the connecting gap between the accommodating tank body 100 and the lower shell 21 to prevent atomized water vapor from entering the lower chamber 201 through the connecting gap between the accommodating tank body 100 and the lower shell 21, causing a short circuit in the electronic system 30.

[0047] At the same time, the limiting ribs 211 and the abutting ribs 212 extending from the inner wall of the lower shell 21 can limit and fix the mounting ring 13, and the abutting ring 213 extending from the upper opening of the lower shell 21 can fix the cylindrical groove wall 14, which can well fix the accommodating groove body 100 and provide better stability.

[0048] Specifically, in this embodiment, the sealing matching structure between the abutting ring 213 and the upper opening end of the cylindrical groove wall 14 is as follows: a sealing ring 15 with a "T"-shaped cross section is also provided between the abutting ring 213 and the upper opening end of the cylindrical groove wall 14, and the sealing ring 15 has a first arm (not shown) extending upward, a second arm (not shown) extending downward, and a third arm (not shown) extending inward, and the third arm is provided between the abutting ring 213 and the upper opening end of the cylindrical groove wall 14, the first arm is embedded in the lower shell 21, and the second arm is located on the outer side of the cylindrical groove wall 14, and the sealing structure is stable and has a good sealing effect. Of course, in other embodiments, the sealing structure is not limited to this.

[0049] Further, continue to refer to Fig.13 As shown, the housing further comprises an upper housing 25, an inner cover 24, a medicine box 26, a mist quantity adjusting member 27 and a mask 28. The inner cover 24 is sealed to the upper opening of the lower housing 21. The inner cover 24 has an upper opening 241. The upper housing 25 covers the outer side of the inner cover 24. The medicine box 26 is arranged on the upper housing 25 and is located at the upper end of the upper opening 241 of the inner cover 24. The upper housing 25 also has a mist outlet 251 located at the top of the medicine box 26. The mist quantity adjusting member 27 is arranged at the mist outlet 251. The mask 28 is connected to the upper housing 25, and the mist outlet 251 is located in the mask 28. The water vapor after heating and atomization flows out from the upper opening 241 of the inner cover 24, passes through the medicine box 26, and is dispersed to the mist outlet 251 of the upper housing 25. The medicine box 26 can be placed with auxiliary treatment drugs, etc. The mask 28 fits the user's face for the user to inhale. The mist volume adjustment member 27 adjusts the flow area of ​​the mist outlet 251 to adjust the mist volume. Of course, in other embodiments, the structure of the housing is not limited thereto.

[0050] Specifically, the atomizer provided by this solution and the conventional atomizer sheet (glass glaze coating heating sheet) in the prior art are used as examples. Under the condition that the structure remains unchanged, the noise test data with the atomizer sheet as a variable is shown in Table 1. The conventional atomizer uses the glass glaze coating heating sheet as an example, and the atomizer of this solution uses the ceramic heating sheet of the above-mentioned composite material. It can be clearly seen that the atomizer of this solution reduces the noise by an average of about 5bd and the maximum by 12bd compared with the conventional atomizer. It has a significant noise reduction effect.
