Description

Technical Field

[0001] The present invention relates to the technical field of atomizing devices, and in particular to an atomizing assembly and a humidifier. Background Art

[0002] The atomizer assembly is a common device for atomizing water. Current atomizer assemblies consist of a housing, atomizer disc, sealing ring, pressure ring, and float. The atomizer disc is installed within the atomizer chamber of the housing. The pressure ring is screwed to the atomizer chamber to pressurize and secure the disc within the chamber. To quickly dissipate the heat generated by the atomizer disc during operation, the housing and pressure ring are made of metal materials such as copper or stainless steel.

[0003] Because the atomizer assembly must be fully or partially submerged in liquid during operation, the metal housing and metal pressure ring are susceptible to corrosion. Even stainless steel housings can be corroded in some special applications due to prolonged contact with corrosive liquids, such as disinfectants. Currently, plastic is generally not considered for atomizer assembly housings. Although plastic offers low cost, light weight, and corrosion resistance, plastic housings made entirely of plastic have poor heat dissipation performance and cannot meet operational requirements.

[0035] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0036] In the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions of various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0037] One embodiment of the present invention, as Figures 1 to 5 As shown, an atomization assembly is provided, including a plastic outer shell 100, a metal inner shell 200, an atomization element 300, a pressure ring and a sealing structure.

[0038] The plastic housing 100 is provided with a structural hole 110. Optionally, the material of the plastic housing 100 is selected from any one of ABS material, PP material, PC material, and PC / ABS material, but is not limited to the above materials. The shape of the structural hole 110 is preferably a circular hole, but other shapes are also possible.

[0039] The metal inner shell 200 has a first shell wall 210 and a second shell wall 220 connected to each other. The first shell wall 210 is embedded in the plastic shell 100. The first shell wall 210 serves to increase the heat dissipation area. The heat of the first shell wall 210 can be conducted outward through the plastic shell 100. Although the thermal conductivity of the plastic shell 100 is relatively weak, by embedding the first shell wall 210 in the plastic shell 100, the thickness (wall thickness) of the plastic shell 100 can be reduced while ensuring structural strength. The thinner the thickness of the plastic shell 100, the better its thermal conductivity.

[0040] The second shell wall 220 protrudes from the structural hole 110 and forms a receiving cavity 221 below the structural hole 110. Specifically, the metal inner shell 200 is made of any one of aluminum, steel, or copper, or alloys thereof, but is not limited thereto.

[0041] The atomizing element 300 is disposed in the accommodating chamber 221. Optionally, the atomizing element 300 is an atomizing sheet.

[0042] The pressing ring includes a metal pressing ring 400 and a plastic pressing ring 500. Optionally, the material of the metal pressing ring 400 is selected from any one of aluminum, steel or copper, or an alloy of the above materials, but not limited to the above materials. The material of the plastic pressing ring 500 is selected from any one of ABS material, PP material, PC material, PC / ABS material, but not limited to the above materials. The metal pressing ring 400 includes a connecting ring 410 and a pressing ring head 420. The pressing ring head 420 is embedded in the plastic pressing ring 500. The connecting ring 410 protrudes from the plastic pressing ring 500. The connecting ring 410 is connected to the second shell wall 220 through the structural hole 110 and abuts the atomizer 300 to fix the atomizer 300 in the accommodating chamber 221. Compared with the pressing ring of the integral plastic, the metal pressing ring 400 has the advantage of not being easy to loosen, and at the same time, the thermal conductivity is higher, and it can dissipate heat quickly. In particular, the atomizer generally breaks up the liquid water molecular structure through high-frequency resonance to produce naturally flowing water mist. The metal pressure ring 400 can avoid loosening due to high-frequency resonance, thereby improving the working stability of the atomizer component.

[0043] The sealing structure is provided on the outside and inside of the connecting ring 410 to prevent the liquid from contacting the connecting ring 410 and the second shell wall 220 from the outside and inside of the pressing ring, and the liquid contacts the atomizer 300 through the plastic pressing ring 500.

[0044] The accommodating chamber 221 for accommodating the atomizer 300 in the atomizer assembly is made of a second shell wall 220 made of metal. In this way, the heat generated by the atomizer 300 during operation can be quickly dissipated through the metal inner shell 200. By embedding the first shell wall 210 of the metal inner shell 200 into the plastic outer shell 100, and then using a sealing structure to prevent the liquid from contacting the connecting ring 410 and the second shell wall 220 from the outside and inside of the pressing ring, the metal outer shell and the metal pressing ring 400 are prevented from contacting the liquid and being corroded. The assembly has the characteristics of good heat dissipation performance and good corrosion resistance. In addition, the use of plastic instead of part of the metal material can reduce material costs.

[0045] In some embodiments, a mounting cavity 140 is formed in the plastic housing 100 , and the second housing wall 220 is exposed outside the mounting cavity 140 . Heat generated by the atomizer 300 during operation can be dissipated to the mounting cavity 140 through the second housing wall 220 .

[0046] In some embodiments, as Figure 2 and Figure 3 As shown, the sealing structure includes a first sealing ring 600, which is arranged between the plastic housing 100 and the plastic pressing ring 500 to prevent liquid from contacting the connecting ring 410 (metal) and the second shell wall 220 (metal) from the outside of the pressing ring.

[0047] Further, if Figure 2 and Figure 3 As shown, a first rib 120 is provided on the plastic housing 100 . The first rib 120 is arranged around the outer side of the structural hole 110 . A first sealing surface 130 is provided between the first rib 120 and the edge of the structural hole 110 .

[0048] A circle of second ribs 510 is provided on the bottom side of the plastic pressing ring 500, and the second ribs 510 are located on the inner side of the first ribs 120. A second sealing surface 520 is provided between the second ribs 510 and the bottom outer peripheral edge 530 of the plastic pressing ring 500, and the second sealing surface 520 is located above the first sealing surface 130.

[0049] The first sealing ring 600 is disposed between the first sealing surface 130 and the second sealing surface 520 and between the first rib 120 and the second rib 510 .

[0050] In this way, the liquid outside the pressing ring cannot flow into the gap between the pressing ring and the plastic housing 100, thereby playing an anti-corrosion role.

[0051] In some embodiments, as Figure 2 and Figure 3 As shown, the sealing structure includes a second sealing ring 700, which is arranged between the plastic pressing ring 500, the atomizer 300 and the metal pressing ring 400 to prevent liquid from contacting the connecting ring 410 and the second shell wall 220 from the inner side of the pressing ring.

[0052] Furthermore, if Figure 2 and Figure 3 As shown, a circle of third ribs 550 is provided along the circumference of the inner peripheral edge 540 of the bottom side of the plastic pressing ring 500 , and a third sealing surface 560 is provided on the bottom side of the plastic pressing ring 500 outside the third ribs 550 .

[0053] The second sealing ring 700 is disposed between the third sealing surface 560 , the top surface of the atomizer 300 , and the inner wall surface of the metal pressing ring 400 .

[0054] In this way, the liquid inside the pressing ring cannot flow in through the gap between the pressing ring and the atomizer 300, which also plays a role in corrosion prevention. Combined with the first sealing ring 600, liquid is blocked from both the inside and the outside.

[0055] In some embodiments, as Figure 2 and Figure 3 As shown, in order to improve the bonding strength between the plastic pressure ring 500 and the metal pressure ring 400, a first flange 421 extending outward is provided at the top of the pressure ring head 420, and the first flange 421 is combined in the plastic pressure ring 500; a second flange 422 extending inward is provided below the top of the pressure ring head 420, and the second flange 422 is combined in the plastic pressure ring 500.

[0056] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 As shown, to prevent liquid intrusion from affecting the normal operation of the electronic components, the atomizer assembly also includes a third sealing ring 800. The third sealing ring 800 is disposed within the accommodating chamber 221 and abuts the bottom surface of the atomizer 300. The bottom of the accommodating chamber 221 is provided with a through hole 222, and the bottom of the third sealing ring 800 is provided with a sealing plug 810. The sealing plug 810 is disposed through the through hole 222, and the bottom surface of the third sealing ring 800 is in close contact with the bottom surface of the accommodating chamber 221. The atomizer 300 is connected to an elastic conductive member 310, which passes through the sealing plug 810.

[0057] Optionally, the elastic conductive member 310 is a spring connected to an electrode of the atomizer 300. If the atomizer has two electrodes, there should be two elastic conductive members 310 connected to the two electrodes respectively. The spring passes through the sealing plug 810 and is connected to the circuit board 900, which is disposed within the plastic housing 100.

[0058] In some embodiments, as Figure 4 and Figure 5As shown, the top surface of the plastic pressing ring 500 is provided with a first concave notch 570, and the first concave notch 570 is used for inserting a tool to rotate the plastic pressing ring 500. The top surface of the metal pressing ring 400 is provided with a second concave notch 430, and the first concave notch 570 is embedded in the second concave notch 430 to enhance the bonding strength between the plastic pressing ring 500 and the metal pressing ring 400.

[0059] In some embodiments, as Figure 5 As shown, the plastic outer shell 100 and the metal inner shell 200 have the same shape. The plastic outer shell 100 includes a first top wall and a first side wall. Correspondingly, the first shell wall 210 includes a second top wall and a second side wall. The second top wall is embedded in the first top wall, and the second side wall is embedded in the first side wall.

[0060] Another embodiment of the present invention provides a humidifier, comprising a water tank and an atomizing assembly disposed within the water tank. The specific structure of the atomizing assembly is similar to that of the above embodiments. Since this humidifier utilizes all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, and therefore will not be further elaborated here.

[0061] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
