Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic atomization, and in particular to an electronic atomizer and an atomization device. Background Art

[0002] With the development of electronic cigarettes, or electronic atomizers, technology has led to the emergence of various types of e-cigarettes on the market, such as extended-life e-cigarettes and lightweight e-cigarettes. However, regardless of the type of e-cigarette, when users use the e-cigarette, they cannot know the current level of e-liquid, and therefore cannot know when the e-liquid will run out. Consequently, if the e-cigarette is used when the e-liquid is too low or exhausted, a burnt smell will be produced, affecting the user experience.

[0003] To solve the problem of not being able to promptly inform users when the e-liquid is exhausted or too low, many companies have developed different solutions to achieve real-time monitoring of the e-liquid level and inform users, such as the existing patents CN204599332U and CN204540815U.

[0004] For example, the prior art CN115778018A discloses a method for counting the remaining usage times of an electronic cigarette, which is applied to electronic cigarettes. This technology estimates the remaining number of inhalations of e-liquid based on the number of times a user inhales e-liquid. That is, the total number of inhalations that a cigarette cartridge can provide can be determined based on a preset e-liquid amount and a first e-liquid inhalation amount. After determining the total number of inhalations, the remaining number of inhalations can be determined based on the cumulative number of inhalations, and the remaining number of inhalations can be output. However, the amount of e-liquid inhaled by the user is determined by the output power and duration, and the cumulative number of inhalations and the remaining number of inhalations are also affected by the duration of a single inhalation of e-liquid by the user. Thus, when there is a time difference between the duration of the last e-liquid inhalation and the duration of the current e-liquid inhalation, and the difference between the durations of each e-liquid inhalation is large, there will be a large error between the determined remaining number of inhalations and the actual remaining number of inhalations, resulting in an inaccurate estimated number of remaining inhalations. Consequently, this solution still cannot determine the remaining amount of e-liquid.

[0005] In addition, some e-cigarettes check the oil level by using the usage time. However, the usage time of e-cigarettes will be affected by the amount of oil in a single puff and the atomization power of the oil. Therefore, there is a large error between the read oil level and the actual oil level, which in turn leads to inaccurate oil level data. Utility Model Content

The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0036] like Figure 1 and Figure 2 As shown, the present disclosure provides an electronic atomizer 10 according to an embodiment, comprising an atomizing body 100 , a control component 200 and a liquid level sensor 300 .

[0037] The atomizer body 100 includes a main shell 110 and a smoke liquid atomizer assembly 120. The main shell 110 defines a main cavity 1101, and the smoke liquid atomizer assembly 120 is located in the main cavity 1101. The control assembly 200 includes a shell 210, a battery 220, and a control board 230. The shell 210 is connected to the main shell 110. The shell 210 defines a receiving cavity 2101. The battery 220 and the control board 230 are located in the receiving cavity 2101. The charging and discharging terminals of the battery 220 are electrically connected to the power control terminal of the control board 230. The working control end of the control board 230 is electrically connected to the smoke oil atomizer assembly 120, so that the control board 230 drives the smoke oil atomizer assembly 120 to work according to the power status of the battery 220; the monitoring end of the liquid level sensor 300 is located in the atomization chamber of the smoke oil atomizer assembly 120 to collect the height of the smoke oil liquid level in the atomization chamber of the smoke oil atomizer assembly 120. The liquid level sensor 300 is also sequentially inserted into the through hole of the main shell 110 and the through hole of the shell 210, and the output end of the liquid level sensor 300 is electrically connected to the sampling input end of the control board 230. It can be understood that the liquid level sensor 300 is electrically connected to the control board 230 via a wireless module, and can also be electrically connected to the control board 230 via a wire. The control board 230 is also electrically connected to the smoke oil atomizer assembly 120 via the wireless module to control the atomization state of the smoke oil atomizer assembly 120.

[0038] In this embodiment, the electronic atomizer 10 uses a liquid level sensor 300 to monitor the amount of oil in the oil atomization assembly 120 in real time. The capacitive liquid level sensor calculates the change in liquid level height based on the measured capacitance change, based on the correlation between the laws of the spatial electromagnetic field and the physical changes of the measured liquid. This is a non-contact sensing method that can achieve continuous liquid level and single-point liquid level measurement, providing users with a good experience. Compared to the existing technology, the liquid level sensor 300 used in this solution is used to collect the liquid level information of the oil in the atomization chamber of the oil atomization assembly 120, and transmit the collected oil level height information to the control board 230, so that the control board 230 outputs the liquid level information based on the height to inform the user. Thus, this solution accurately measures the amount of oil by sensing the oil state through capacitance. It is understood that when the liquid level sensor 300 cannot sense the liquid in the atomization chamber, the control board 230 feeds back the received liquid level status, i.e., the liquid level is too low. At this time, the control board 230 controls the battery 220 to stop supplying power to the liquid atomization assembly 120, thereby interrupting the heating and atomization of the liquid in the atomization chamber. When the liquid level sensor 300 senses the liquid in the atomization chamber, the control board 230 controls the battery 220 to continue supplying power to the liquid atomization assembly 120, thereby continuing the heating and atomization of the liquid in the atomization chamber.

[0039] Further, if Figure 2 As shown, the smoke oil atomization assembly 120 includes an atomization shell 121, an atomization seat 122, a central tube 123, a heating wire (not shown) and oil-absorbing cotton 124. The atomization seat 122 is installed on the inner wall of the atomization shell 121, and the central tube 123 is connected to the atomization seat 122. An atomization bin is formed between the atomization shell 121, the atomization seat 122 and the central tube 123. The atomization bin is connected to the central tube 123. The oil-absorbing cotton 124 is located in the atomization bin. The monitoring end of the liquid level sensor 300 is electrically connected to the oil-absorbing cotton 124. The heating wire is arranged on the inner wall of the central tube 123, and the heating enabling end of the control board 230 is electrically connected to the heating wire. Figure 6As shown, the liquid level sensor 300 includes a sensing unit and differential capacitors C1, C2, C3, and C4. The sensing unit is electrically connected to the control board 230. The monitoring terminal of the liquid level sensor 300 is a differential capacitor, which uses the positive and negative plates of the capacitor to detect the remaining amount of tobacco oil absorbed by the oil-absorbing cotton pad 124. The differential capacitor uses the difference in dielectric constant of different substances. Through amplification, digital conversion, and compensation calculation of small changes in capacitance by the sensing unit, it senses the material composition and then converts the current data into liquid level data. Finally, the sensing unit of the liquid level sensor 300 transmits the data to the control board 230 via IIC communication, allowing the control board 230 to accurately read the current liquid level information and output the data. The tobacco oil acts as a medium between the positive and negative plates of the differential capacitor, allowing the current remaining tobacco oil amount to be calculated based on the dielectric constant of the tobacco oil, thereby enabling the control board 230 to accurately read the tobacco oil level information with minimal error. Furthermore, the model of the sensing unit is MDC04. In this embodiment, a portion of the structure of the liquid level sensor 300 abuts against the inner wall of the central tube 123 .

[0040] like Figure 3 and Figure 4 As shown, in one embodiment, the main shell 110 is provided with a first opening 1102, the housing 210 is provided with a second opening 2102, and the smoke oil atomizing assembly 120 is provided with a third opening 1201. Figure 2 As shown, the liquid level sensor 300 is sequentially disposed through the third port 1201, the first port 1102, and the second port 2102, and is electrically connected to the control board 230. It can be understood that the first port 1102, the second port 2102, and the third port 1201 all serve to provide a safe position for the liquid level sensor 300, ensuring that the connection between the atomizer body 100 and the control assembly 200 does not affect the overall structure of the electronic atomizer 10, preventing any structural distortion, and thus improving the flatness of the electronic atomizer 10. In this embodiment, the third port 1201 is disposed on the atomizer housing 121.

[0041] In one embodiment, the control assembly 200 further includes a power socket (not shown) disposed within the housing 210. The power connection terminal of the power socket is electrically connected to the sensing control terminal of the control board 230, and the liquid level sensor 300 is also electrically connected to the contact terminal of the power socket. It will be understood that after the liquid level sensor 300 makes electrical contact with the power socket, the e-liquid level information read by the liquid level sensor 300 will be transmitted to the control board 230 through the power socket, allowing the control board 230 to receive the corresponding information. Furthermore, the power socket is electrically connected to the control board 230 via a wire.

[0042] like Figure 1 and Figure 2As shown, in one embodiment, the control component 200 also includes a display screen 240, and the display screen 240 is installed on the outside of the shell 210, and the display screen 240 is electrically connected to the status information display enable end of the control board 230. It can be understood that the display screen 240 is located on the outside of the shell 210. After the liquid level sensor 300 obtains the current smoke oil liquid level height information, it sends the data to the control board 230 through IIC communication, so that the control board 230 can accurately read the current liquid level status information and display the relevant information on the display screen 240, so that the user can know the current remaining oil amount of the smoke oil. Therefore, when the smoke oil content in the atomization bin is too low or insufficient, the display screen 240 will display the information that the current liquid level is too low or exhausted, thereby achieving the purpose of promptly informing the user when the smoke oil is insufficient, and avoiding the user from continuing to use the smoke oil when the smoke oil is insufficient, resulting in a burnt smell when the smoke oil is atomized. Of course, the display screen 240 will also display the power information and atomization power of the electronic atomizer 10, which also serves to inform the user. Further, as Figure 5 As shown, the outer wall of the housing 210 is provided with a receiving groove 2103, and the display screen 240 is installed in the receiving groove 2103. When the display screen 240 is installed in the receiving groove 2103, the overall structure of the electronic atomizer 10 is relatively flat, and no part of the structure is abrupt. This also makes it easier for the user to hold the electronic atomizer 10 without feeling uncomfortable.

[0043] like Figure 2 As shown, in one embodiment, the control component 200 further includes a control button 250, which is embedded in the housing 210, and the control button 250 is electrically connected to the key signal enable end of the control panel 230. In this embodiment, the control button 250 is an information status switching button. It can be understood that by clicking the control button 250, that is, the information status switching button, information related to the electronic atomizer 10, such as the battery 220 power, atomization power, current amount of e-liquid, current working status, etc., the user can know the current relevant information and perform corresponding processing according to the current information, such as charging the electronic atomizer 10, adjusting the atomization power, adding e-liquid, replacing the oil-absorbing cotton 124, etc.

[0044] Further, if Figure 2 and Figure 5 As shown, the control assembly 200 also includes a charging port 260, which is located outside the housing 210 and is electrically connected to the charging enable terminal of the control board 230. It will be understood that the charging port 260 is used for wiring, allowing the battery 220 to be charged while connected. Typically, when not connected to the charging port 260, the battery 220 provides power to the control board 230. When the battery 220 is low or depleted, the user can recharge the battery 220 by connecting a charging cable.

[0045] like Figure 2 As shown, in one embodiment, the liquid level sensor 300 is located at the connection point between the atomization bin and the central tube 123. It can be understood that since the liquid level sensor 300 is used to collect the information of the liquid level of the e-liquid and send it to the control panel 230 so that the control panel 230 displays the liquid level information, and the connection point between the atomization bin and the central tube 123 is located near the atomization seat 122, the liquid level sensor 300 can accurately collect the liquid level of the e-liquid. When the liquid level of the e-liquid is higher than the connection point, the control panel 230 obtains the liquid level of the e-liquid and outputs information that the liquid level is sufficient. At this time, the user can continue to use the electronic atomizer 10. When the liquid level of the e-liquid is lower than the connection point, the control panel 230 obtains the liquid level of the e-liquid and outputs information that the liquid level is too low or insufficient, so as to promptly inform the user and prevent the control panel 230 from stopping the atomization of the e-liquid in the atomization bin, thereby preventing the heating wire from continuing to heat and causing a burnt smell when the e-liquid is atomized.

[0046] like Figure 2 As shown, in one embodiment, the atomizing body 100 further includes an atomizing nozzle 130, part of the structure of the atomizing nozzle 130 is located in the main body cavity 1101, and the atomizing nozzle 130 is respectively connected to the main body shell 110 and the smoke oil atomizing assembly 120. In this embodiment, the atomizing nozzle 130 is connected to the central tube 123. It can be understood that when the user draws the action of the electronic atomizer 10 toward the atomizing nozzle 130, the control board 230 senses the action of drawing the electronic atomizer 10, and then drives the heating wire to heat and atomize the smoke oil, so that the atomized smoke oil enters the central tube 123, and finally enters the user's mouth through the atomizing nozzle 130, completing the action of drawing the smoke oil.

[0047] The present disclosure also provides an atomization device, comprising the electronic atomizer 10 of any one of the above embodiments.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] The electronic atomizer 10 uses a liquid level sensor 300 to monitor the amount of oil in the oil atomization assembly 120 in real time. It uses a capacitive liquid level sensor based on the correlation between the laws of the spatial electromagnetic field and the physical changes of the measured liquid. The change in the liquid level is calculated based on the measured capacitance value change. This is a non-contact sensing method that can achieve continuous liquid level and single-point liquid level measurement, providing users with a good experience. Compared with the existing technology, the liquid level sensor 300 used in this solution is used to collect the liquid level information of the oil in the atomization chamber of the oil atomization assembly 120, and transmit the collected oil level height information to the control board 230, so that the control board 230 outputs the liquid level information based on the height to inform the user. Thus, this solution accurately measures the amount of oil by sensing the oil state through capacitance.

[0050] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
