Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to a novel electronic cigarette oil supply device and an electronic cigarette. Background Art

[0002] The electronic cigarette injects the smoke oil into the atomization chamber, and the heating wire in the atomization chamber heats the liquid smoke oil to atomize it into steam. In the prior art, the smoke oil is usually injected into the atomization chamber by using oil-absorbing cotton or an oil pump.

[0003] For example, a Chinese patent with publication number CN217089595U discloses a double-oil cup electronic cigarette, including a main body, multiple heaters, a fluid transfer element, a counter chip and a controller, the main body has a suction port and an air inlet leading to the main body and connected to each other, a plurality of oil cups are arranged in the main body, and the oil cups respectively have an atomization chamber for receiving removable consumables, and the atomization chamber is connected to the suction port and the air inlet; multiple heaters are used to vaporize the consumables; the fluid transfer element is used to transfer the consumables from the atomization chamber to the corresponding heater through capillary action; the counter chip is configured to count the number of puffs of each oil cup after the heater is started; the controller is configured to selectively trigger one of the groups of heaters to start according to the number of counts of the counter chip after the external airflow enters from the air inlet; the utility model proposes a double-oil cup electronic cigarette, the purpose of which is to be able to maintain the taste restoration for a longer time without attenuation, so as to improve the customer experience. The oil is injected into the atomizer chamber by means of oil-absorbing cotton. Since the capillary suction principle is adopted, the concentration of the oil in the atomizer chamber is relatively high when it is used for the first time. After the oil is atomized, the oil in the atomizer chamber is reduced. Since the oil-absorbing cotton absorbs oil relatively slowly, the oil in the atomizer chamber cannot be replenished in time, resulting in a higher concentration of the first atomization and a lower concentration of the second atomization. And when used continuously, the concentration of the oil in the atomizer chamber will become lower and lower. The user's taste will become worse and worse, and even cause the heating wire in the atomizer chamber to dry burn.

[0004] And the Chinese patent with publication number CN208850681U discloses a new type of electronic cigarette, including a shell, an oil storage tank, an atomizer core assembly, and a power supply. A separation ring is provided between the atomizer core assembly and the shell, a baffle is provided in the oil storage tank, the upper part of the baffle is a collection tank with a cavity structure, and an electromagnetic valve connecting the collection tank and the oil storage tank is provided on the baffle. A suction nozzle is provided at one end of the cover body away from the shell, and a condensation cap is provided at the upper end of the atomizer core assembly. A one-way oil pump is provided in the oil storage tank, and an oil pipe is connected to the one-way oil pump. A control panel is provided on the outside of the shell, and the control panel is electrically connected to the power supply, and the power supply is electrically connected to the atomizer core assembly and the one-way oil pump. The utility model can adjust the oil intake at any time according to personal preferences and taste, bringing more personalized experience to users; it can prevent fried oil and large-particle oil mist from being directly inhaled into the mouth, improving user experience, and can condense and divert; it can recycle condensed oil and seepage oil to avoid overflow, improve user experience, and reduce waste. The oil pump is used to inject the e-liquid into the atomizer chamber. Although the oil pump can inject the e-liquid into the atomizer chamber in time, when the oil pump stops working, the e-liquid in the atomizer chamber will flow back along the oil pump pipe or evaporate from the atomizer chamber and fall outside the atomizer chamber. Therefore, the e-liquid content in the atomizer decreases after the oil pump stops working. When the user uses it for the first time, the reaction time required for the oil pump to inject the e-liquid into the atomizer chamber is greater than the reaction time for the heating wire in the atomizer chamber to atomize. That is to say, when the atomizer chamber has begun to atomize the residual e-liquid in the atomizer chamber for the first time, the oil pump has not yet injected the e-liquid into the atomizer chamber in time. As a result, the concentration of the first atomization is lower, and the concentration of the second atomization is higher than that of the first atomization. This affects the user experience.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] For example, see Figure 1-2 As shown, the utility model relates to a novel electronic cigarette oil supply device, which has a shell composed of an upper shell 01 and a lower shell 02, and an atomizer column 03 is integrally formed on the top of the upper shell 01. An upper chamber is provided in the upper shell 01, and a lower chamber is provided in the lower shell 02. A mounting plate 04 is provided in the upper chamber. The outer surface of the mounting plate 04 is fixedly connected to the inner wall of the upper chamber. An atomizer assembly 05 is fixedly mounted on the mounting plate 04. The end of the atomizer assembly 05 is fixedly connected to the atomizer column 03. The opening of the upper chamber is sealed by the mounting plate 04. A sealed soaking chamber 06 is formed in the upper shell 01. By storing tobacco oil in the soaking chamber 06, the atomizer core in the atomizer assembly 05 is in contact with the tobacco oil in the soaking chamber 06 regardless of whether it is in a working state or a non-working state. When the atomizer assembly 05 is working, since the atomizer core in the atomizer assembly 05 is in contact with the e-liquid all the time, the atomizer assembly 05 can atomize the e-liquid in the soaking chamber 06 immediately, and there is no need to wait for the e-liquid to enter the atomizer assembly 05 before atomization. At the same time, the concentration of a single atomization is basically the same. In addition, the dry burning of the atomizer assembly 05 is avoided, so the response speed is faster than the traditional atomizer assembly 05 through the capillary effect or the oil pump 18 directly supplies oil to the atomizer assembly 05.

[0022] In order to ensure that the atomizer core in the atomizer assembly 05 is always located in the e-liquid in the soaking chamber 06, a liquid supply device is provided in the lower shell 02 to supply oil to the soaking chamber 06 when the atomizer assembly 05 is working, thereby ensuring that the e-liquid in the soaking chamber 06 is always in a saturated state.

[0023] A partition plate 07 is vertically installed in the lower chamber, and the partition plate 07 divides the lower chamber into an installation chamber 08 and a storage chamber 09. A storage bin 10 and an oil pump 18 for storing tobacco oil are provided in the storage chamber 09, and a one-way solenoid valve 11 and a battery 12 for providing power to the solenoid valve 11 are fixedly installed in the installation chamber 08. The design of the one-way solenoid valve 11 prevents the tobacco oil in the soaking chamber 06 from flowing back into the storage bin 10. The input end of the solenoid valve 11 is connected to the output end of the oil pump 18 through a pipeline. The input end of the oil pump 18 is located at the bottom of the storage bin 10. The output end of the solenoid valve 11 is connected to the soaking chamber 06 through a pipeline.

[0024] The smoke oil in the soaking chamber 06 is atomized by the atomizing assembly 05 and sucked out from the atomizing column 03 by the user. After the smoke oil is atomized, the smoke oil in the soaking chamber 06 will decrease. During the decrease process (during the operation of the atomizing assembly 05), the oil pump 18 is started, and the smoke oil enters the soaking chamber 06 from the storage bin 10 through the one-way electromagnetic valve 11 under the action of the oil pump 18, thereby replenishing the amount of smoke oil consumed by the atomizing assembly 05 at a time. This ensures that the smoke oil in the soaking chamber 06 is always kept in a saturated state.

[0025] A PCB board 13 and a button 14 are also provided in the installation chamber 08. One end of the button 14 extends to the outside of the lower housing 02. The PCB board 13 is electrically connected to the battery 12, the atomizer assembly 05, the oil pump 18 and the solenoid valve 11. When the user presses the button 14, the oil pump 18 and the atomizer assembly 05 are simultaneously controlled to start synchronously through the PCB board 13. The purpose of the synchronous start is to ensure that the tobacco oil in the soaking chamber 06 is delivered to the soaking chamber 06 in time during the atomization process. At the same time, the purpose of controlling the extension and stop of the oil pump 18 is to ensure that the tobacco oil in the soaking chamber 06 always maintains a certain storage amount. When the oil pump 18 is just started, it takes a certain amount of time for the tobacco oil in the storage bin 10 to enter the soaking chamber 06. However, the atomizer directly atomizes the tobacco oil. Therefore, there is a time difference between the atomization component starting to atomize the e-liquid and the e-liquid in the storage bin 10 entering the soaking bin under the action of the oil pump 18. For those skilled in the art, how to control the synchronous start of the oil pump 18 and the atomization component 05 and the delayed stop of the oil pump 18 through the PCB board 13 belongs to the prior art and will not be described here. Therefore, it is necessary to control the delayed stop of the oil pump 18 through the PCB board 13 to make up for the amount of e-liquid consumed in the time difference.

[0026] For example, the capacity of the soaking chamber 06 is set to 2ML, and the capacity of the storage bin 10 is set to 10ML. During use, 2ML of e-liquid is injected into the soaking chamber 06, and 10ML of e-liquid is injected into the storage bin 10. The user starts the atomizer assembly 05 and the oil pump 18 by pressing the button 14. When the atomizer assembly 05 starts working, the e-liquid in the soaking chamber 06 is atomized, and the e-liquid in the soaking chamber 06 is reduced. During the process of atomizing the e-liquid, the oil pump 18 replenishes the e-liquid in the storage bin 10 into the soaking chamber 06 in time. The e-liquid in the soaking chamber 06 or other e-liquid is always kept at 2ML, thereby ensuring that the atomizer core of the atomizer assembly 05 is always in a soaked state.

[0027] In order to accelerate the diffusion of the gas flowing out of the atomizing assembly 05, the atomizing column 03 is provided with an air outlet 15 which is connected to the atomizing assembly 05, and the air outlet 15 is arranged in a trumpet shape in the atomizing column 03. When the gas atomized by the atomizing assembly 05 passes through the air outlet 15, the gas can diffuse quickly in the air outlet 15, thereby improving the user's experience.

[0028] In order to facilitate the injection of tobacco oil into the storage bin 10, a filling pipe 16 is provided in the installation chamber 08, one end of which is connected to the bottom of the storage bin 10, and the other end of which is located at the top of the installation chamber 08. In order to prevent tobacco oil from flowing out from the end of the filling pipe 16, a connector 17 adapted to the filling pipe 16 is fixedly mounted on the installation plate 04. One end of the connector 17 is located in the soaking chamber 06. The design of the connector can not only seal the filling pipe 16, but also prevent the tobacco oil in the storage bin 10 from flowing out of the filling pipe 16. When the connector is removed from the installation plate, it is also convenient for the user to inject liquid into the soaking chamber 06.

[0029] In order to ensure that the pressure in the storage bin 10 is balanced after the smoke oil in the storage bin 10 is reduced, so that the oil pump 18 can smoothly transport the smoke oil in the storage bin 10 to the soaking chamber 06, an air inlet is provided at the top of the storage bin 10, and a one-way valve or a one-way cloth is fixedly installed in the air inlet. The one-way valve can be a manual one-way valve or an electromagnetic one-way valve. The one-way valve or the one-way cloth ensures the pressure balance in the storage bin 10 and prevents the smoke oil in the storage bin 10 from flowing out of the air inlet.

[0030] It should be noted that the smoke oil described in this application can be other liquids. The same effect can also be achieved. At the same time, the above-mentioned atomization component 05 is a prior art. A Chinese patent disclosed as CN117441955A can be used to disclose an electronic cigarette oil atomizer, including a main body component, wherein the main body component includes a shell, an internal thread, a base, an oil storage tank, an oil inlet channel, a first spring, a baffle, an oil guide cotton core, a scale line, an oil storage chamber, an oil guide cotton plate, a first sealing ring, a second sealing ring, a partition, an electric heating wire, a heating chamber and a smoke pipe; the present invention stores part of the electronic cigarette oil through the oil storage tank. When the atomizer as a whole tilts, the spring pushes the baffle to close the oil inlet channel, and the oil will be stored in the oil storage tank. Therefore, the oil inside the oil storage tank can still maintain contact with the oil guide cotton core, ensuring that the cotton core can conduct oil normally, and avoiding the oil guide cotton core from being affected by its life due to failure to be fully wetted. By arranging the oil guide cotton core inside the electric heating wire and arranging the arc-shaped oil guide cotton plate outside it, the heat generated by the electric heating wire can be fully utilized, the heat loss is reduced, the heat utilization rate is improved, and the battery life of the battery 12 is improved.

[0031] See also Figure 3 As shown, the second embodiment is different from the above embodiments in that an oil pump 18 is fixedly installed in the soaking chamber 06, a one-way solenoid valve 11 and a battery for providing power to the solenoid valve 11 are fixedly installed in the installation chamber 08, and the soaking chamber 06 is connected to the storage bin 10 by a filling pipe 16. It should be noted that the soaking chamber 06 and the storage bin 10 can be connected by providing a connecting hole in the connector described in the first embodiment. The input port of the oil pump 18 is connected to the connector by a pipeline. The output port of the oil pump 18 is connected to the soaking chamber 06. The output end of the solenoid valve 11 is connected to the storage bin 10 by a pipeline, and the input end of the solenoid valve 11 is connected to the atmosphere. When in use, the atomizer assembly 05, the oil pump 18 and the solenoid valve 11 are started at the same time. When the solenoid valve 11 is opened, the air in the atmosphere enters the storage bin 10 through the solenoid valve 11, ensuring the atmospheric pressure balance in the storage bin 10. Under the action of the oil pump 18, the tobacco oil in the storage bin 10 enters the soaking chamber 06 in turn through the filling pipe 16 and the connector, thereby replenishing the tobacco oil consumed by the atomizer assembly 05 at a time. This ensures that the atomizer assembly 05 is always immersed in the tobacco oil in the soaking chamber 06. It should be noted that the solenoid valve 11 described in this application can be a one-way valve or a multi-position solenoid valve and other valve bodies that can realize the forward, reverse, closed and other directional control of fluid media such as liquids and gases.
