Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette substitute technical field, especially a kind of oil content detection atomizer and electronic atomization device. BACKGROUND

[0002] Electronic atomization device is an electronic product that simulates cigarette, which can atomize tobacco tar into smoke for users to smoke. Due to the similar taste and convenience of electronic atomization device to cigarette, electronic atomization device is rapidly promoted and used.

[0003] The existing electronic atomization device generally includes a battery host and an atomizer. The atomizer is a smoke generating part of the electronic atomization device, and the atomizer stores tobacco tar. High temperature can atomize the tobacco tar into smoke. The battery host is the control center and power supply part of the electronic atomization device. The amount of tobacco tar in the oil tank of the atomizer gradually decreases with high-temperature atomization. However, for the electronic atomization device, since most of the oil tanks are built-in the shell, the amount of tobacco tar in the oil tank cannot be seen from the outside. If the electronic atomization device is used without knowing the amount of tobacco tar, the oil wick and heating wire in the atomizer can be easily burned out due to insufficient oil, the smoker can smoke to a bad taste, the smoker's health can be harmed, and the electronic atomization device can be damaged.

[0004] Currently, the judgment methods for the amount of tobacco tar in the industry include: 1. Software calculation. The amount of tobacco tar consumed in a unit of time at a specific power is fixed, and the approximate relationship between the total amount of tobacco tar and the smoking time can be calculated. During the smoking process, the time of each smoking is accumulated, and the remaining oil amount is obtained by subtracting the time of the smoking process from the total time. 2. Float ball liquid level detection. The amount of liquid is determined by the up-and-down floating of the float ball. When the liquid level rises, the float ball floats up. When the liquid level decreases, the float ball sinks. 3. Pressure type liquid level detection. The pressure type liquid level meter determines the liquid level height by measuring the liquid pressure. It converts the pressure signal into a liquid level height value through a formula. 4. Capacitive liquid level detection. The liquid level height is determined by measuring the change of the capacitance value. The electrodes are installed inside and outside the container. When the liquid level rises or falls, the capacitance value changes. According to this change, the height of the liquid level can be determined. 5. Ultrasonic liquid level detection. The transmission time of ultrasonic waves is used to measure the liquid level height. The transmission time of ultrasonic waves from the transmitter to the liquid surface is measured by emitting ultrasonic wave pulses. According to the wave speed and transmission time, the height of the liquid level can be determined.

[0005] However, the software calculation cannot accurately evaluate the amount of tobacco tar because the amount of tobacco tar consumed in a unit of time at full battery is more than that at not full battery. The float ball liquid level detection structure is complex and cannot be sealed. The pressure type liquid level detection has high implementation cost and difficult structure implementation. The capacitive liquid level detection and ultrasonic liquid level detection have complex electronic circuit design and high cost. They cannot well meet the needs of actual use. Utility Model Content

[0006] Therefore, it is necessary to provide an atomizer and electronic atomization device for detecting e-liquid inventory that is simple to implement, low in cost, and capable of accurately assessing the above problems, with both structural and electronic design being uncomplicated.

[0007] An e-liquid level detection atomizer includes a housing, a base, and an atomizing assembly. The housing includes a mouthpiece end and an open end. The base is inserted into the open end of the housing and forms an e-liquid storage chamber and an atomizing chamber inside the housing. The e-liquid storage chamber is connected to the atomizer via an oil guide hole. The atomizing assembly is disposed within the atomizing chamber and guides e-liquid into the e-liquid storage chamber via the oil guide hole. The atomizer also includes an e-liquid level detection assembly, which includes a Hall sensor and a magnetic dipole. The magnetic dipole is disposed within the e-liquid storage chamber and floats up and down with the e-liquid level in the storage chamber. The Hall sensor is disposed outside the e-liquid storage chamber and outputs an analog voltage signal based on the magnetic field strength generated by the magnetic dipole to determine the e-liquid level in the storage chamber.

[0008] In one embodiment, the Hall sensor is a linear Hall sensor, the magnetic dipole is a bar magnet including an N pole and a S pole, and the N pole and the S pole are located below the liquid surface and above the liquid surface in the oil storage cavity, respectively, and the linear Hall sensor is directly opposite the magnetic dipole.

[0009] In one embodiment, the oil quantity detection component is provided with two linear Hall sensors, which are respectively disposed at the bottom and top of the oil storage chamber, and the magnetic dipole is located between the two Hall sensors.

[0010] In one embodiment, a limiting element is provided in the oil storage cavity, which restricts the magnetic dipole to float only in the direction of the liquid level in the oil storage cavity.

[0011] In one embodiment, the limiting member is provided with a limiting groove extending from the bottom of the oil storage cavity to the top of the oil storage cavity, and the magnetic dipole is partially embedded in the limiting groove, and the magnetic dipole moves within the limiting groove.

[0017] This e-liquid level detection atomizer uses an e-liquid level detection component. A magnetic dipole, positioned on the e-liquid surface within the reservoir, floats up and down with the e-liquid level. The entire height from the bottom to the top of the reservoir defines the dipole's range of movement. The dipole generates a magnetic field within the reservoir. A Hall sensor, located outside the reservoir, detects the strength of this magnetic field. As the dipole floats up and down, the analog voltage output by the Hall sensor changes; a stronger magnetic field results in a higher analog voltage. The Hall sensor determines the e-liquid level based on the magnitude of this output voltage signal. The structural and electronic design of this e-liquid level detection component is simple, cost-effective, and does not compromise the reservoir's sealing performance. It accurately detects the e-liquid level within the atomizer, preventing burnt-out components that could affect its lifespan and vaping experience. Attached Figure Description

[0026] Please see Figure 1 This is a schematic diagram of the electronic atomizing device in one embodiment.

[0027] Please see Figure 1 , Figure 2 The atomizer 10 is an aerosol generator in an electronic atomization device, used to generate heat when powered on, causing the e-liquid inside the atomizer 10 to form an aerosol for the user to inhale. This e-liquid level detection atomizer 10 includes a housing 12, a base 14, and an atomizing assembly 16. The housing 12 includes a mouthpiece end and an open end. The base 14 is inserted into the open end of the housing 12 and forms an oil storage chamber 122 and an atomizing chamber 124 inside the housing 12. The oil storage chamber 122 is connected to the atomizer 10 via an oil guide hole. The atomizing assembly 16 is disposed within the atomizing chamber 124, and the atomizing assembly 16 guides oil to the oil storage chamber 122 via the oil guide hole. The atomizer also includes an e-liquid level detection function. The detection component 18 includes a Hall sensor 182 and a magnetic dipole 184. The magnetic dipole 184 is disposed inside the oil storage cavity 122 and floats up and down with the height of the e-liquid in the oil storage cavity 122. The Hall sensor 182 is disposed outside the oil storage cavity 122. The Hall sensor 182 outputs an analog voltage signal based on the magnetic field strength generated by the magnetic dipole 184 to determine the amount of e-liquid in the oil storage cavity 122.

[0028] The e-liquid level detection atomizer 10 incorporates an e-liquid level detection component 18. A magnetic dipole 184 is positioned on the e-liquid surface within the e-liquid reservoir 122, floating up and down with the e-liquid level. The entire height from the bottom to the top of the reservoir 122 defines the floating range of the magnetic dipole 184, which generates a magnetic field within the reservoir 122. A Hall sensor 182 is positioned outside the reservoir 122 to detect the strength of the magnetic field generated by the magnetic dipole 184. As the magnetic dipole 184 floats up and down on the e-liquid surface, the analog voltage output by the Hall sensor 182 changes; the stronger the magnetic field, the higher the analog voltage. The Hall sensor 182 determines the e-liquid level within the reservoir 122 based on the magnitude of the output analog voltage signal. The structure and electronic design of the oil level detection component 18 are not complicated, making it simple to implement and low in cost. It does not affect the sealing performance of the oil storage chamber 122 and can accurately detect the e-liquid level in the atomizer 10, thereby avoiding the burning of the atomizer component 16, which would affect its service life and the vaping experience.

[0029] Please see Figure 3 In this embodiment, the Hall sensor 182 is a linear Hall sensor, and the magnetic dipole 184 is a bar magnet including an N pole and a S pole, with the N pole and S pole located below and above the liquid surface in the oil reservoir 122, respectively. The linear Hall sensor is directly opposite the magnetic dipole 184. The magnetic dipole 184 generates a magnetic field within the oil reservoir 122, with magnetic field lines flowing from the S pole to the N pole. In the field of the magnetic dipole 184, the magnetic induction intensity is inversely proportional to the square of the distance, and the magnetic induction intensity is almost zero at locations far from the magnetic dipole 184. As the magnetic dipole 184 floats up and down with the liquid surface in the oil reservoir 122, the distance between it and the Hall sensor 182 also changes, thereby affecting the analog voltage output by the Hall sensor 182.

[0030] Specifically, using a linear Hall sensor (IC HAL4901), the strength of an external magnetic field can be detected, and an analog voltage signal can be output. The stronger the external magnetic field, the larger the output analog voltage. The magnetic field range of the linear Hall sensor is ±100GS; the sensitivity is 15mV / GS. For this linear Hall sensor package, pin 1 (VDD) is connected to the positive power supply; pin 2 (GND) is connected to the negative power supply; pin 3 is the analog voltage output pin, which outputs different analog voltage values ​​depending on the strength of the magnetic field detected by the linear Hall sensor. For example, if VDD is 5V, the output voltage at pin 3 (OUT) will be as follows: Figure 4 As shown. The closer the S pole of the magnet is to the linear Hall sensor, the smaller the output voltage at pin 3 (OUT), which is close to 0V; the closer the N pole is to the linear Hall sensor, the larger the output voltage at pin 3 (OUT), which is close to 5V.

[0031] Furthermore, the oil level detection assembly 18 is equipped with two linear Hall sensors, which are respectively located at the bottom and top of the oil reservoir 122, with a magnetic dipole 184 positioned between the two Hall sensors 182. That is, the linear Hall sensors include a first linear Hall sensor and a second linear Hall sensor. The first linear Hall sensor is located at the top of the oil reservoir 122, and the second linear Hall sensor is located at the bottom of the oil reservoir 122, with the first and second linear Hall sensors arranged in opposite directions. Specifically, the closer the S pole of the magnetic dipole 184 is to the first linear Hall sensor, the smaller the output analog voltage value; the farther the S pole of the magnetic dipole 184 is from the first linear Hall sensor, the larger the output analog voltage value. Similarly, the farther the S pole of the magnetic dipole 184 is from the second linear Hall sensor, the smaller the output analog voltage value; and the closer the S pole of the magnetic dipole 184 is to the second linear Hall sensor, the larger the output analog voltage value.

[0032] The magnetic dipole 184 floats up and down with the liquid level. The height from the bottom to the top of the entire e-liquid reservoir 122 is the floating range of the magnetic dipole 184, corresponding to the total liquid level of the e-liquid in the reservoir 122. When the magnetic dipole 184 floats to a certain liquid level, the output voltage of the OUT pin can be detected by two Hall sensors 182 according to the above theory. Then, by referring to the voltage-liquid level scale of the reservoir 122, the e-liquid content in the reservoir 122 can be determined. Of course, the e-liquid content in the reservoir 122 can be measured by a single Hall sensor 182. Using two Hall sensors 182 to collect data makes the measurement results more accurate and precise. Table 1 can be referenced as a table showing the correspondence between oil level and output voltage when VDD is 4V. The S pole of the magnetic dipole faces the first linear Hall sensor, and the N pole of the magnetic dipole faces the second linear Hall sensor. The magnetic dipole is tested from the moment it approaches the first linear Hall sensor to the moment it approaches the second linear Hall sensor, with a total range of 33.02mm. The distance and output voltage have an approximately linear relationship, and the spacing can be derived by following the output voltage.

[0033] Table 1:

[0034]

[0035] Please see Figure 2In this embodiment, a limiting member 126 is provided inside the oil storage cavity 122. The limiting member 126 restricts the magnetic dipole 184 to float only in the direction of the liquid level in the oil storage cavity 122. The limiting member 126 can restrict the direction and movement trajectory of the magnetic dipole 184, preventing the magnetic dipole 184 from rolling or drifting when it floats with the liquid surface. Rolling would cause the N pole and S pole of the magnetic dipole 184 to be swapped, resulting in inaccurate measurement results, or drifting would change the distance between the magnetic dipole 184 and the Hall sensor 182, resulting in inaccurate measurement results. Therefore, the limiting member 126 can make the magnetic dipole 184 move along a preset movement trajectory, thereby improving the accuracy and reliability of the results.

[0036] Preferably, the limiting member 126 is provided with a limiting groove extending from the bottom to the top of the oil storage cavity 122. The magnetic dipole 184 is partially embedded in the limiting groove, and the magnetic dipole 184 moves within the limiting groove. The distance between the limiting groove and the inner wall of the oil storage cavity 122 is slightly greater than the width of the magnetic dipole 184, so that the magnetic dipole 184 can float up and down with the liquid surface without rolling. The width of the limiting groove is slightly greater than the thickness of the magnetic dipole 184, so that it can accommodate part of the magnetic dipole 184 without affecting the up and down floating of the magnetic dipole 184 on the liquid surface, and also prevents the magnetic dipole 184 from rolling. Of course, in other embodiments, the limiting member 126 can also be other forms of limiting, such as a limiting frame, a limiting frame, or a limiting rod.

Since this electronic atomizing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0038] In this embodiment, the battery host 20 is equipped with a main control board 22. The Hall sensor 182 is electrically connected to the main control board 22, and the three pins of the Hall sensor 182 are respectively connected to the positive terminal of the power supply, the negative terminal of the power supply, and the output voltage. The main control board 22 is equipped with a program that correlates the output voltage with the e-liquid level, and the e-liquid level can be determined based on the output voltage. The connection between the Hall sensor 182 and the main control board 22 does not affect other circuits, and can achieve independent detection without affecting other performance aspects of the electronic atomization device.

[0039] In this embodiment, the battery host 20 is equipped with an indicator light that displays different colors to indicate the e-liquid level in the e-liquid reservoir 122. By displaying the color of the indicator light to remind the user of the e-liquid level, it can promptly alert them when the e-liquid is low, preventing the atomizing component 16 from dry-burning, which could lead to scorching and affect its lifespan and vaping experience. Of course, in other embodiments, the method of indicating the e-liquid level can also be voice prompts, vibration alerts, or other methods.

[0040] In this embodiment, the battery host 20 is equipped with a display screen that shows the amount of e-liquid in the oil storage chamber 122. The display screen clearly shows the amount of e-liquid, and it also makes the electronic atomizing device look more technological. Of course, the display screen can also display time, temperature, weather, voltage, and even human vital signs data as needed and according to the design of the main control board 22.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
