Description

[Technical field]

[0001] The present invention relates to a split type electronic cigarette, more specifically, a split type ultrasonic atomization type electronic cigarette or other types of electronic cigarettes.

Technical Background

[0002] Chinese patents CN107752129A, CN105876873B, CN205432145U, CN105962421B, etc. disclose an ultrasonic atomizer for electronic cigarettes, or ultrasonic atomization electronic cigarettes.

[0003] During use or research, it was found that the ultrasonic atomizer head in the ultrasonic atomization electronic cigarette is extremely susceptible to damage compared with other electronic cigarettes or ultrasonic atomization electrical appliances for other purposes (such as humidifiers, water replenishing devices, etc.) (due to high-frequency use every day), and more than 80% of the damage is to the ultrasonic atomization head, mechanical damage such as switch failure and shell damage accounts for less than 1%, and the rest is damage to electronic components. The service life of the ultrasonic atomization head is much lower than that of other components, while the cost of other components, especially circuit boards, is much higher than that of the ultrasonic atomization head. The damage to electronic components is mainly caused by circuit boards, or the cost of circuit boards is higher than that of electronic components such as batteries.

[0004] The damage of other types of electronic cigarettes is similar to that of ultrasonic atomizer electronic cigarettes, but the damage rate of atomizers is much lower than that of ultrasonic atomizers. Among other types of electronic cigarettes, the damage rate of atomizers is about 50%, the damage rate of other electronic components is about 30-40%, and the damage rate of non-electronic components is about 10-20%. The cost and / or damage rate of circuit boards are generally higher than other electronic components such as batteries.

[0005] The reason for the damage of ultrasonic atomizer head is that the micropores with a diameter of only several microns in the key microporous component that assists atomization are blocked by the components in the atomized liquid, especially the insoluble components, especially the inevitable insoluble particles. The soluble solid components may precipitate solids or crystallize due to the volatilization of solvents, which may also block the micropores and make it difficult to reopen them for a while. The lower the solubility, the more difficult it is to reopen them. Insoluble droplets, such as oil, can also block the micropores. It is basically difficult to reopen the micropores after being blocked by insoluble particles or insoluble droplets. Therefore, its damage rate is extremely high.

[0006] The reason for the damage of other types of electronic cigarette atomizer heads is basically that the heating wire is burned out. The main reason is that the smoke oil is carbonized on the surface of the heating wire, which makes the heat dissipation of the heating wire poor and the heating wire temperature is too high and melts. Therefore, its damage rate is lower than that of ultrasonic atomizer heads.

[0007] The current ultrasonic atomization electronic cigarette is designed to fix the atomizer head and other components, especially the circuit board, in an integrated design. When the atomizer head fails, maintenance is extremely inconvenient, and usually the entire electronic cigarette or the atomizer head and the circuit board (such as the electronic cigarette disclosed in CN211631789U) or the battery and the circuit board can only be discarded together, which causes a serious waste of resources and seriously increases the cost of use. In addition, excessive disposal of the battery will also cause environmental pollution.

[0008] Therefore, in reality, there is a need for an ultrasonic atomization electronic cigarette that is easy to maintain, has low usage costs, reduces resource waste, and has high resource utilization efficiency. [Summary of the invention]

[0009] The purpose of the present invention is to provide an ultrasonic atomization electronic cigarette, which is easy to maintain, has a lower use cost, higher resource utilization efficiency, and less resource waste.

[0010] The inventors of the present invention unexpectedly discovered that by using a separate structure for the ultrasonic atomization head and the body containing the circuit board in the ultrasonic atomization electronic cigarette, or by using a separate structure for them and other electronic components such as a battery, part or all of the above-mentioned purposes can be achieved.

[0011] The present invention has been accomplished based on the above findings.

[0012] The present invention relates to an ultrasonic atomization electronic cigarette, which comprises an ultrasonic atomization head and a body containing a circuit board (for driving the ultrasonic atomization head), wherein the ultrasonic atomization head and the body containing the circuit board adopt a split structure.

[0013] The present invention also relates to an ultrasonic atomization electronic cigarette, which comprises an ultrasonic atomization head, a body containing a circuit board (for driving the ultrasonic atomization head) and a body containing a battery. The ultrasonic atomization head, the body containing the circuit board and the body containing the battery adopt a split structure, and the body containing the circuit board and the body containing the battery also adopt a split structure.

[0026] The ultrasonic atomization head comprises an ultrasonic atomization sheet and further comprises a component containing micropores for assisting atomization.

[0027] The body containing the circuit board also includes a battery, such as a lithium battery.

[0028] A preferred embodiment is:

[0029] 1) The ultrasonic atomizing head is connected and fixed to the body containing the circuit board through a connecting sleeve thread, and the electrical connection between the two is achieved through a metal contact connection.

[0032] Preferably, the electrical connection point on the bottom surface or the top surface of the connecting sleeve is a metal block with magnetic induction, and the electrical connection point on the bottom surface or the top surface of the other connecting sleeve is a magnet block.

[0033] Because the split is more convenient and quick, another more preferred implementation is:

[0034] 2) The ultrasonic atomizing head is connected and fixed to the body containing the circuit board by plug-in connection, plug-in connection or magnetic attraction, and the electrical connection between the two is achieved by contact connection of electrical connection points (such as metal contacts) or plug-in connection of electrical conductors (such as metal).

[0035] The bottom end of the ultrasonic atomizer shell is provided with a lower connecting sleeve, and the top of the body shell containing the circuit board is provided with an upper connecting sleeve, one of which is a hollow sleeve and the other is a solid sleeve; when the ultrasonic atomizer head is connected to the body containing the circuit board, one connecting sleeve is inserted into the other connecting sleeve. Preferably, there is also a clamping structure in the connecting sleeve to connect in a fixed direction.

[0036] A more preferred embodiment is as follows,

[0037] The above-mentioned body containing the circuit board is provided with a recessed snap-in groove, the inner diameter of which is substantially the same as the outer diameter of the lower connecting portion of the above-mentioned ultrasonic atomizing head, and is in an interference fit with the lower connecting portion of the above-mentioned ultrasonic atomizing head, and the lower connecting portion of the above-mentioned ultrasonic atomizing head is snapped into the snap-in groove.

[0040] Preferably, the above-mentioned snap-in groove also has a snap-in for fixing the direction, and the above-mentioned connecting portion also has a protrusion for fixing the direction which basically matches the above-mentioned (fixing) snap-in.

[0045] Beneficial effects:

[0046] Compared with other components such as circuit boards, ultrasonic atomizer heads have a much higher (accounting for more than 80%) damage rate and / or lower production cost; compared with non-electronic components such as ultrasonic atomizer heads, circuit boards have a higher production cost and / or lower damage rate; compared with other electronic components such as batteries, circuit boards have a higher damage rate and / or higher production cost.

[0047] Therefore, by separating the ultrasonic atomizer head from the body containing the circuit board or separating them from other electronic components such as a battery, there is no need to discard the entire electronic cigarette or the atomizer head and the circuit board or the battery and the circuit board together when a failure occurs, which is conducive to preserving components with higher costs and / or less prone to failure; removing broken or old components with lower costs and / or prone to failure; replacing them with new components with lower costs; reducing the cost of use and reducing resource waste; making more efficient use of resources; and making maintenance more convenient.

[0048] Due to higher frequency of use or different atomization mechanisms, the ultrasonic atomizer head for electronic cigarettes has a higher damage rate (more than 50% higher than their atomizer heads) compared to other ultrasonic atomizer appliances or other electronic cigarettes. Therefore, separating the ultrasonic atomizer head for electronic cigarettes from the body containing the circuit board or separating them from other electronic components such as batteries is more conducive to preserving components with higher costs and / or less prone to failure; more conducive to removing broken or old components with lower costs and / or prone to failure; more conducive to replacing with new components with lower costs; more conducive to reducing use costs and reducing resource waste; more conducive to more efficient use of resources; and more convenient maintenance.
