Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of an acid-proof electronic atomization controller with good consistency, and particularly relates to an acid-proof electronic atomization controller with good consistency. BACKGROUND

[0002] A conventional acid-proof electronic atomization controller with good consistency has a flat plate capacitor composed of a polar plate, a gasket and a copper ring film in its internal structure. The polar plate is generally a porous polar plate, and the copper ring film is composed of a copper ring and a diaphragm attached to one end of the copper ring. When smoking, a negative pressure is provided through an air hole at the bottom of the shell to make the diaphragm close to the porous polar plate, so that the capacitance of the flat plate capacitor is increased, and thus the chip in the acid-proof electronic atomization controller with good consistency can output a high level when detecting the increased capacitance, indicating that the atomizer of the electronic cigarette has completed atomization.

[0003] The tobacco oil of the electronic cigarette contains acidic components. After being atomized, the tobacco oil flows through the inside of the acid-proof electronic atomization controller with good consistency, which causes the metal layer on the diaphragm to be corroded, and the diaphragm to become loose, resulting in the failure of the electronic cigarette after smoking, such as the delay of the indicator light.

[0004] Therefore, the acid-proof electronic atomization controller with good consistency needs to be designed to be acid-proof. The conventional acid-proof design can change the material of the diaphragm, such as changing the metal layer from nickel plating to other acid-resistant materials to improve the corrosion resistance. However, due to the structural limitation of the large inner diameter of the diaphragm, the area of the diaphragm bonded to the copper ring is small, especially the part bonded between the diaphragm and the copper ring is easily corroded, which makes the diaphragm more likely to become loose, and the acid-proof ability needs to be optimized.

[0005] REFERENCE Figure 1 FIG. 1 shows an existing acid-proof electronic atomization controller with good consistency. The structure of the acid-proof electronic atomization controller with good consistency is that the diaphragm 01 is attached to the 0.2 mm thick copper ring 02. Among them, the chip 04 on the circuit board (PCB) 03 generally has a large volume, and the circuit board 03 also needs to be opened with an air hole and needs to pass through a wire, which causes the inner diameter of the copper ring 02 to be relatively large, thereby limiting the thickness of the copper ring 02 to be relatively thin. Therefore, the bonding area of the diaphragm 01 and the copper ring 02 is relatively small, and the area of the diaphragm 01 is relatively large, which makes the bonding part easy to be corroded, and the diaphragm 01 is very easy to become loose after being corroded. CONTENT OF THE INVENTION

[0006] The technical problem solved by the present application is to provide an acid-proof electronic atomization controller with good consistency to help improve the looseness of the diaphragm caused by acid corrosion and improve the consistency.

[0007] The application discloses an acid-proof electronic atomization controller with good consistency, which comprises a diaphragm assembly, wherein the diaphragm assembly comprises a diaphragm ring in the shape of a bottomed cylinder, and a diaphragm is attached to the bottom of the diaphragm ring and covers a through hole in the bottom.

[0008] In some optional embodiments, the diaphragm ring comprises an integrally formed cylinder wall and a cylinder bottom, and the inner diameter of the cylinder wall is greater than the diameter of the through hole.

[0009] In some optional embodiments, the distance from the outer edge of the diaphragm ring to the through hole is D1, and the thickness of the cylinder wall is D2, and D1 is greater than or equal to 2*D2.

[0010] In some optional embodiments, the cylinder wall and the cylinder bottom are in the shape of L in the longitudinal section direction.

[0011] In some optional embodiments, the material of the diaphragm ring is copper.

[0012] In some optional embodiments, both sides of the diaphragm are provided with a plating layer, and the material of the plating layer is nickel-phosphorus alloy or stainless steel.

[0013] In some optional embodiments, the diaphragm assembly further comprises a porous electrode plate below the diaphragm, and a gasket between the diaphragm and the porous electrode plate, wherein the diameter of the through hole is less than or equal to the inner diameter of the gasket.

[0014] In some optional embodiments, the diaphragm assembly further comprises a housing accommodating the diaphragm assembly, the gasket and the porous electrode plate, a cavity between the housing and the diaphragm ring, and a circuit board closing the housing, wherein the inner side of the circuit board is attached with a chip, and the outer side of the circuit board is provided with an indicator light.

[0015] In some optional embodiments, the bottom of the housing is provided with a front air hole, and a dustproof net covering the front air hole is attached to the bottom.

[0016] In some optional embodiments, the circuit board is provided with a rear air hole.

[0017] From the above technical solutions, it can be seen that the application has the following advantages:

[0018] The acid-proof electronic atomization controller with good consistency provided by the application has a bottomed cylinder-shaped membrane ring, so the area of the bottom used for bonding the diaphragm is increased, the bonding force between the diaphragm and the membrane ring is enhanced, the diaphragm can be better tensioned, and the diaphragm is prevented from becoming slack; in addition, due to the increased bonding area, the contact resistance between the diaphragm and the membrane ring is reduced, and the performance consistency of the acid-proof electronic atomization controller with good consistency can be improved. Therefore, the acid-proof electronic atomization controller with good consistency provided by the application has a larger bonding area of the diaphragm and the membrane ring, the bonding is more reliable, the acid corrosion bonding area is almost negligible relative to the entire bonding area, so the diaphragm is less likely to become slack, thereby improving the corrosion resistance of the diaphragm and improving the consistency of the disclosed product. For the current customer requirements for acid-proof and sensitivity, the acid-proof electronic atomization controller with good consistency provided by the application can quickly solve the problem, can improve the storage time of the product at the customer end, and reduce the risk of defects at the customer end. At the same time, the acid-proof electronic atomization controller with good consistency provided by the application improves the structure of the membrane ring, but does not increase the cost technology, and can be solved by using existing equipment and process technology.

[0025] The application will be described in detail below with specific embodiments.

[0026] Reference Figure 2 and Figure 3 The application provides an acid-proof electronic atomization controller with good consistency.

[0027] The acid-proof electronic atomization controller with good consistency comprises a diaphragm assembly, which comprises a diaphragm ring 11 and a diaphragm 12. The diaphragm ring 11 is in the shape of a bottomed cylinder, and a through hole 111 is formed in the bottom of the diaphragm ring 11. The diaphragm 12 is attached to the bottom of the diaphragm ring 11 and covers the through hole 111.

[0028] Here, the diaphragm ring 11 in the shape of a bottomed cylinder can comprise an integrally formed cylinder wall 112 and a cylinder bottom 113, and the through hole 111 is formed in the cylinder bottom 113. The inner diameter of the cylinder wall 112 is greater than the diameter of the through hole 111.

[0029] Optionally, the distance between the outer edge of the diaphragm ring 11 and the through hole 111 is D1, and the thickness of the cylinder wall 112 is D2. Therefore, D1 is greater than D2, and preferably, D1 is greater than or equal to 2*D2.

[0030] Optionally, in the longitudinal cross-sectional direction, the cylinder wall 112 and the cylinder bottom 113 are in the shape of L.

[0031] Optionally, the diaphragm ring 11 is made of metal, such as copper.

[0032] Optionally, one side surface or both side surfaces of the diaphragm 12 has a plating layer, and the material of the plating layer can be nickel, or a nickel-phosphorus alloy or stainless steel with better acid-proof performance.

[0033] Reference Figure 1 The acid-proof electronic atomization controller with good consistency further comprises a porous electrode plate 13 below the diaphragm 12 and a gasket 14 between the diaphragm 12 and the porous electrode plate 13. Optionally, the diameter of the through hole 111 is less than or equal to the inner diameter of the gasket 14. The gasket 14 is made of insulating material, such as plastic, and is used to separate the porous electrode plate 13 and the diaphragm 12.

[0034] Further, the membrane ring 11 is accommodated in a housing 15, and a gasket 14 and a porous electrode plate 13 are accommodated in the housing 15. A cavity 16 is formed between the housing 15 and the membrane ring 11. A circuit board 17 is arranged in the housing 15, and a chip 18 is arranged on an inner side of the circuit board 17. An indicator lamp 19 is arranged on an outer side of the circuit board 17. An upper end of the membrane ring 11 is electrically connected to the circuit board 17.

[0035] Further, a front air hole is formed in a bottom of the housing 15, and a dustproof screen 20 is arranged on the front air hole.

[0036] Further, a rear air hole is formed in the circuit board 17.

[0037] In the embodiment, the radius of the membrane ring is r, and the area of the bottom of the membrane ring 11 that can be used to bond the diaphragm 12 is:

[0038] S=πr 2 -π(r-D1) 2 =2rD1-D1 2 ;

[0039] The area of the bottom of the conventional membrane ring that can be used to bond the diaphragm 12 is:

[0040] S’=πr 2 -π(r-D2) 2 =2rD2-D2 2 ;

[0041] Therefore, the bondable area S of the application is much larger than the bondable area S’ of the conventional membrane ring.

[0042] For example, in a commonly used product, r=3mm, D2=0.2mm, and if D1=0.5mm, then:

[0043] S=2.75mm 2 , S’=1.16mm 2 , S is 2.37 times S’.

[0044] In summary, the application provides an acid-proof electronic atomization controller with good consistency. The membrane ring is improved from a bottomless cylinder to a bottomed cylinder. Therefore, the area of the bottom used for bonding the diaphragm increases, the bonding force between the diaphragm and the membrane ring increases, the diaphragm can be better tensioned, and the diaphragm can be prevented from becoming loose. In addition, due to the increase in the bonding area, the contact resistance between the diaphragm and the membrane ring is reduced, and the performance consistency of the acid-proof electronic atomization controller can be improved. Therefore, the diaphragm of the acid-proof electronic atomization controller has a larger bonding area with the membrane ring, the bonding is more reliable, and the acid corrosion bonding area is almost negligible relative to the entire bonding area. Therefore, the diaphragm is less likely to become loose, thereby improving the corrosion resistance of the diaphragm and the consistency of the disclosed product. For the current customer requirements for acid resistance and sensitivity, the acid-proof electronic atomization controller can quickly solve the problem, can improve the storage time of the product at the customer end, and can reduce the risk of defects at the customer end. At the same time, although the structure of the membrane ring is improved, the cost and technology of the acid-proof electronic atomization controller are not increased, and the existing equipment and process can be used to solve the problem.
