Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomizer with uniform heating. Background Technology

[0002] Electronic atomizers generally refer to electronic cigarettes. An electronic cigarette is an electronic product that mimics a cigarette, having the same appearance, smoke, taste, and feel. It is an atomizer powered by a rechargeable lithium polymer battery.

[0003] In existing technology, electronic atomizers typically include a battery, a heating wire, and a fuel tank. The atomized liquid in the fuel tank permeates to the surface of the heating wire through the wicking cotton. The battery powers the heating wire, which directly heats the atomized liquid at a high temperature. During the high-temperature heating process, the temperature of the heating wire inside the atomizer can usually reach several hundred degrees (usually around 200 degrees) or higher. The vapor is then expelled from the atomizer through its exhaust channel for the user to inhale.

[0004] Regarding the aforementioned technologies, during the process of smoke being transmitted to the outside world, varying degrees of heat loss occur due to differences in ambient temperature, resulting in a poor taste for users. Therefore, there are drawbacks such as difficulty in controlling the smoke temperature and a poor user experience. Summary of the Invention

[0005] In order to make vapor temperature control more precise and improve the user experience of using the atomizer, this application provides an electronic atomizer with uniform heating.

[0006] This application provides an electronic atomizer with uniform heating, employing the following technical solution:

[0007] An electronic atomizer with uniform heating includes a housing and an air outlet disposed at one end of the housing. The housing includes an atomizing section and a vapor delivery section. The atomizing section includes a battery, a main control board, an atomizing core, and a liquid storage chamber. The battery supplies power to the main control board, which is electrically connected to the atomizing core. The atomizing core is connected to the liquid storage chamber, which stores atomized liquid. The main control board drives the atomizing core to generate vapor from the atomized liquid. The vapor delivery section is disposed between the atomizing core and the air outlet, and is used to guide the vapor generated by the atomizing core to the air outlet. The vapor delivery section contains a temperature measuring element and a heating element. The temperature measuring element measures the temperature of the vapor and feeds back the information to the main control board. The heating element is electrically connected to the main control board and is used to heat the vapor delivered within the vapor delivery section.

[0008] By adopting the above technical solution, when the electronic atomizer needs to adjust the temperature, the shell is divided into two parts: the atomizing section and the vapor delivery section. The atomizing section contains a battery, a main control board, an atomizing core, and a liquid storage chamber. The battery supplies power to the main control board, which drives the atomizing core to work and generate heat. The atomizing core heats and vaporizes the atomized liquid in the liquid storage chamber. The vapor enters the vapor delivery section and is guided to the air outlet. The temperature sensor measures the temperature of the vapor in the vapor delivery section and transmits the temperature information to the main control board for data processing. The main control board determines the degree of heat loss of the vapor at the ambient temperature and controls the heating element to work, heating the vapor delivered in the vapor delivery section to compensate for the temperature loss during the vapor delivery process. Finally, the vapor at a suitable temperature is delivered to the user through the air outlet, thereby adjusting the vapor to the predetermined temperature and improving the user's experience of using the atomizer.

[0009] Optionally, the temperature measuring element includes at least a first temperature sensor and a second temperature sensor. The first temperature sensor is disposed at one end of the smoke conveying section near the atomizing core, and the second temperature sensor is disposed at one end of the smoke conveying section near the air outlet. Both the first temperature sensor and the second temperature sensor are electrically connected to the main control board.

[0010] By adopting the above technical solution, when it is necessary to test the temperature inside the smoke conveying section, the temperature measuring element includes a first temperature sensor and a second temperature sensor. The first temperature sensor measures the temperature of the smoke entering the smoke conveying section from the atomizing core, obtains the initial smoke temperature, and feeds it back to the main control board. The second temperature sensor measures the temperature of the smoke entering the exhaust port from the smoke conveying section, obtains the final smoke temperature, and feeds it back to the main control board. The main control board combines the initial smoke temperature and the final smoke temperature to determine the heat loss during the transmission process, making the heating element's temperature adjustment more precise and improving the user's taste experience.

[0011] Optionally, the smoke conveying section is provided with a straight pipe and a spiral pipe, the spiral pipe is wrapped around the periphery of the straight pipe, and a heating mesh is provided inside the straight pipe, the heating mesh being electrically connected to the main control board.

[0012] By adopting the above technical solution, when using the electronic atomizer at different ambient temperatures, the smoke delivery section includes a straight pipe and a spiral pipe. A heating mesh is fixedly embedded inside the straight pipe, while the spiral pipe coils around the periphery of the straight pipe, increasing the smoke delivery path. When the smoke needs to be kept warm or heated, it is quickly guided from the atomizer core to the outlet through the straight pipe. The heating mesh heats the smoke within the straight pipe, compensating for heat loss during transmission and facilitating smoke warming or heating. When the smoke needs to be cooled, it is coiled and transported from the atomizer core to the outlet through the spiral pipe, extending the transmission path and thus increasing heat loss, which is beneficial for cooling the smoke.

[0013] Optionally, a vacuum layer is provided around the periphery of the straight pipe, and ventilation holes are provided on the side wall of the smoke conveying section.

[0014] By adopting the above technical solution, when the smoke is transmitted in the straight pipe, a vacuum layer is set around the straight pipe to reduce the heat exchange between the straight pipe and the outside, thereby reducing the heat loss of the smoke in the straight pipe; when the smoke is transmitted in the spiral pipe, ventilation holes are opened on the side wall of the smoke conveying part, so that the airflow from the outside enters the smoke conveying part and exchanges heat with the side wall of the spiral pipe, thereby increasing the heat loss of the smoke in the spiral pipe and thus improving the cooling effect.

[0015] Optionally, a switching element is provided at one end of the smoke delivery section near the atomizing core. The switching element is used to connect the straight pipe or the spiral pipe, and the switching element is electrically connected to the main control board.

[0016] By adopting the above technical solution, when the smoke needs to be kept warm or heated, the main control board drives the switching component to open the straight pipe and block the spiral channel, so that the smoke is guided from the atomizing core to the outlet through the straight pipe, reducing heat loss during the smoke transmission process; when the smoke needs to be cooled, the main control board drives the switching component to open the spiral pipe and block the straight pipe, so that the smoke is guided to the second air chamber through the spiral pipe, extending the smoke transmission path and increasing heat loss during the smoke transmission process. Thus, the main control board can control the switching component to change the smoke propagation path to meet the temperature regulation requirements of the smoke, which is conducive to more precise smoke temperature control and improves the user's taste experience.

[0017] Optionally, a miniature cylinder is provided at the end of the smoke delivery section away from the atomizing core. The miniature cylinder is electrically connected to the main control board, and a blocking plate is fixedly connected to the piston rod of the miniature cylinder. The blocking plate is used to open and close the air outlet.

[0018] By adopting the above technical solution, when the temperature of the smoke at the outlet differs significantly from the preset taste temperature, the main control board drives the micro cylinder to close the outlet, causing the smoke to linger in the smoke conveying section, thus prolonging the heating or cooling time of the smoke. When the temperature information from the second temperature sensor is close to the preset taste temperature, the main control board drives the micro cylinder to open the outlet, thereby delivering smoke that meets the user's needs and improving the user's taste experience.

[0019] Optionally, a resistor disk is electrically connected between the main control board and the atomizing core. The resistor disk is embedded with multiple resistor blocks of different resistance values, and an insulating sheet is provided between two adjacent resistor blocks.

[0020] By adopting the above technical solution, when the main control board controls the heating of the atomizing core, a resistance disk is electrically connected between the main control board and the atomizing core. By moving the position of the resistance disk, different resistance blocks are connected between the main control board and the atomizing core, changing the current flowing through the atomizing core, thereby changing the heating efficiency of the atomizing core, and thus changing the rate of vapor production, meeting the needs of different users and improving the user experience of using the atomizer.

[0021] Optionally, the atomizing core is a ceramic heating core, and the ceramic heating core is honeycomb-shaped.

[0022] By adopting the above technical solution, when the atomizing core needs to heat the atomizing liquid, a ceramic heating core is used, and the ceramic heating core is honeycomb-shaped. On the one hand, the ceramic heating core has the characteristics of strong adsorption and high heat conduction efficiency, which can quickly absorb the atomizing liquid and heat it to form smoke. On the other hand, the honeycomb shape of the ceramic atomizing core can absorb and store more atomizing liquid, so that the air and the atomizing liquid can fully contact each other under the heating action of the ceramic heating core, thereby improving the atomization efficiency of the atomizing liquid.

[0023] Optionally, the ceramic heating core is provided with a protective sleeve around its periphery, the protective sleeve is provided with an oil guide hole around its periphery, and the ceramic heating core is provided with an oil guide protrusion on its side wall. The oil guide protrusion is embedded in the oil guide hole and is used to contact the atomizing liquid.

[0024] By adopting the above technical solution, when a ceramic heating core is required, a protective sleeve is provided around the ceramic heating core. Since the ceramic heating core is relatively brittle, the protective sleeve can protect the ceramic heating core from cracking. At the same time, the ceramic heating core can pass through the oil guide hole through the oil guide protrusion and contact the atomizing liquid, increasing the atomizing liquid absorption rate and improving the atomization efficiency of the atomizing liquid.

[0025] Optionally, the housing is hinged to a movable door at one end near the battery.

[0026] By adopting the above technical solution, when the e-atomizer needs to be used multiple times, a movable door is hinged at the end of the shell near the battery. By opening the movable end of the movable door, the battery can be removed from the shell for replacement, thereby improving the battery life of the e-atomizer.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the electronic atomizer needs to adjust the temperature, the housing is divided into two parts: the atomizing section and the vapor delivery section. The atomizing section contains a battery, a main control board, an atomizing core, and a liquid storage chamber. The battery supplies power to the main control board, which drives the atomizing core to heat up. The atomizing core heats and vaporizes the atomized liquid in the liquid storage chamber. The vapor enters the vapor delivery section and is guided to the air outlet. The temperature sensor measures the temperature of the vapor in the vapor delivery section and transmits the temperature information to the main control board for data processing. The main control board determines the degree of heat loss of the vapor at the ambient temperature and controls the heating element to work, heating the vapor delivered in the vapor delivery section to compensate for the temperature loss during the vapor delivery process. Finally, the vapor at the appropriate temperature is delivered to the user through the air outlet, thereby adjusting the vapor to the preset temperature and improving the user's experience of using the atomizer.

[0029] 2. When it is necessary to test the temperature inside the smoke delivery section, the temperature measuring element includes a first temperature sensor and a second temperature sensor. The first temperature sensor measures the temperature of the smoke entering the smoke delivery section from the atomizing core, obtains the initial smoke temperature, and feeds it back to the main control board. The second temperature sensor measures the temperature of the smoke entering the exhaust port from the smoke delivery section, obtains the final smoke temperature, and feeds it back to the main control board. The main control board combines the initial smoke temperature and the final smoke temperature to determine the heat loss during the transmission process, making the heating element's heating temperature adjustment more precise and improving the user's taste experience.

[0030] 3. When using the electronic atomizer under different ambient temperatures, the vapor delivery section includes a straight pipe and a spiral pipe. A heating mesh is fixedly embedded inside the straight pipe, while the spiral pipe coils around the periphery of the straight pipe, increasing the vapor delivery path. When the vapor needs to be kept warm or heated, it is quickly guided from the atomizer core to the outlet through the straight pipe. The heating mesh heats the vapor within the straight pipe, compensating for heat loss during delivery and facilitating vapor warming or heating. When the vapor needs to be cooled, it is coiled and delivered through the spiral pipe from the atomizer core to the outlet, extending the delivery path and thus increasing heat loss, which is beneficial for vapor cooling.

[0031] 4. When smoke is transmitted in the straight pipe, a vacuum layer is provided around the straight pipe to reduce heat exchange between the straight pipe and the outside, thereby reducing heat loss of smoke in the straight pipe; when smoke is transmitted in the spiral pipe, ventilation holes are opened on the side wall of the smoke conveying part, allowing the outside airflow to enter the smoke conveying part and exchange heat with the side wall of the spiral pipe, thereby increasing the heat loss of smoke in the spiral pipe and improving the cooling effect.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses an electronic atomizer that provides uniform heating. (Refer to...) Figure 1 and Figure 2The electronic atomizer includes a housing 1, which is elongated and has an air outlet 11 at one end. The housing 1 includes two parts: an atomizing section 2 and a vapor delivery section 3. The atomizing section 2 includes, from bottom to top, a battery 21, a main control board 22, an atomizing coil 23, and a liquid storage chamber 24. The battery 21 is installed at the bottom of the housing 1, and a hinged door 8 is installed on the side wall of the housing 1 near the battery 21 to facilitate battery replacement and improve the battery life of the electronic atomizer. The main control board 22 is installed on and in contact with the battery 21, so that the battery 21 supplies power to the main control board 22. The main control board 22 is a circuit board with an MCU chip (microcontroller unit) installed, and the user can set the desired flavor temperature on the main control board 22 as a temperature reference value for comfortable vapor flavor. The atomizing core 23 is installed on the end of the main control board 22 away from the battery 21. An air inlet 12 is provided on the side wall of the housing 1 around the atomizing core 23. The liquid storage chamber 24 is installed on the side wall of the atomizing core 23 and communicates with the atomizing core 23. The liquid storage chamber 24 stores atomizing liquid. The atomizing core 23 absorbs the atomizing liquid and heats it, so that the atomizing liquid produces smoke which is guided to the smoke conveying section 3. The smoke delivery section 3 is located between the atomizing core 23 and the air outlet 11. The smoke is guided to the air outlet 11 through the smoke delivery section 3. It is worth noting that a temperature measuring element 31 and a heating element 32 are fixedly embedded in the smoke delivery section 3. The temperature measuring element 31 measures the temperature of the smoke delivered in the smoke delivery section 3 and feeds the temperature information back to the main control board 22 for comparison with the temperature reference value on the main control board 22. At the same time, the heating element 32 is electrically connected to the main control board 22. In this embodiment, the heating element 32 is a wavy heating wire. The main control board 22 drives the heating element 32 to heat up according to the comparison result, thereby heating the smoke delivered in the smoke delivery section 3, compensating for the heat loss of the smoke during the transmission process, and raising the temperature of the smoke to a level close to the preset temperature. This makes the smoke temperature control more precise and improves the user's experience of using the atomizer.

[0038] Reference Figure 2 Furthermore, the temperature measuring element 31 includes at least a first temperature sensor 311 and a second temperature sensor 312. The first temperature sensor 311 is installed at the end of the smoke conveying section 3 near the atomizing core 23. The first temperature sensor 311 tests the temperature of the smoke introduced into the smoke conveying section 3 by the atomizing core 23, obtains the initial smoke temperature, and feeds it back to the main control board 22. The main control board 22 compares the initial smoke temperature with the temperature reference value and determines whether the smoke entering the smoke conveying section 3 needs to be heated, kept warm, or cooled based on the result. The second temperature sensor 312 is installed at the end of the smoke conveying section 3 near the air outlet 11. The second temperature sensor 312 tests the temperature of the smoke guided from the smoke conveying section 3 to the air outlet 11, obtains the final smoke temperature, and feeds it back to the main control board 22. The main control board 22 compares the final smoke temperature with the temperature reference value and determines whether the smoke has reached the desired taste temperature for the user, thereby making the smoke temperature control more precise.

[0039] Reference Figure 2 Furthermore, the smoke conveying section 3 also includes a straight pipe 33 and a spiral pipe 34. The straight pipe 33 is a long, straight cylinder, and a heating mesh 332 is embedded inside the straight pipe 33. The spiral pipe 34 is coiled around the periphery of the straight pipe 33. If the smoke needs to be kept warm or heated, the smoke introduced into the smoke conveying section 3 is guided from the atomizing core 23 to the air outlet 11 through the straight pipe 33, reducing heat loss during the smoke transmission process. At the same time, the heating mesh 332 can also heat the smoke transmitted in the straight pipe 33, increasing the temperature of the smoke. If the smoke needs to be cooled, it is transmitted from the atomizing core 23 to the air outlet 11 through the spiral pipe 34, extending the transmission path of the smoke in the smoke conveying section 3, increasing heat loss during the smoke transmission process, and thus enhancing the cooling effect of the smoke. Furthermore, a vacuum layer 331 is integrally formed on the periphery of the straight pipe 33. The vacuum layer 331 provides thermal insulation for the straight pipe 33, reducing heat loss during the transfer of smoke in the straight pipe 33. Meanwhile, several ventilation holes 341 are provided on the side wall of the smoke conveying section 3 located on the periphery of the spiral pipe 34, allowing external airflow to enter the smoke conveying section 3 and convect with the smoke transferred in the spiral pipe 34, which helps to enhance the cooling effect.

[0040] Reference Figure 2 Furthermore, a switching element 4 is located at the end of the smoke delivery section 3 near the atomizing core 23. The switching element 4 is located at the inlet of the straight pipe 33 and the spiral pipe 34. In this embodiment, the switching element 4 uses a two-position one-way valve. The switching element 4 is electrically connected to the main control board 22. If the main control board 22 determines that the smoke needs to be kept warm or heated, the main control board 22 sends a command to control the switching element 4 to open the straight pipe 33 and close the spiral pipe 34, so that the smoke generated by the atomizing core 23 enters the straight pipe 33 for transmission, reducing heat loss during transmission or heating the smoke. If the main control board 22 determines that the smoke needs to be cooled, the main control board 22 sends a command to control the switching element 4 to block the straight pipe 33 and open the spiral pipe 34, so that the smoke generated by the atomizing core 23 enters the spiral pipe 34, extending the transmission path, increasing heat loss during transmission, and improving the cooling effect on the smoke, thereby meeting the user's needs under different ambient temperature conditions and improving the user's taste experience.

[0041] Reference Figure 2A miniature cylinder 5 is fixedly installed on the inner wall of the smoke conveying section 3 near the air outlet 11. The miniature cylinder 5 is electrically connected to the main control board 22. A baffle plate 51, which is square in shape, is connected to the piston rod of the miniature cylinder 5. If the end temperature information obtained by the second temperature sensor 312 differs significantly from the preset taste temperature in the main control board 22, the main control board 22 controls the miniature cylinder 5 to extend. The main control board 22 drives the miniature cylinder 5 to extend its piston rod, causing the baffle plate 51 to close the air outlet 11. This causes the smoke to linger in the smoke conveying section 3, prolonging the heating or cooling time of the smoke. When the temperature information of the second temperature sensor 312 is close to the preset taste temperature, the main control board 22 drives the miniature cylinder 5 to retract its piston rod, causing the baffle plate 51 to open the air outlet 11. This ensures that the smoke delivered to the air outlet 11 meets the user's needs, thereby improving the user's taste experience.

[0042] Reference Figure 2 A resistance disk 6 is slidably mounted between the main control board 22 and the ceramic heating core 231. The resistance disk 6 includes multiple resistance blocks 61. In this embodiment, it includes three resistance blocks 61. An insulating sheet 62 is embedded between adjacent resistance blocks 61. Pins 60 are fixedly connected to both the main control board 22 and the ceramic heating core 231, and respectively abut against the upper and lower surfaces of one of the resistance blocks 61. A push rod 63 is connected to the side of the resistance disk 6. The push rod 63 can push the resistance disk 6 to slide between the main control board 22 and the ceramic heating core 231, changing the resistance block 61 connected between the upper and lower pins 60, thereby changing the current flowing into the ceramic heating core 231, thereby changing the heating efficiency of the ceramic heating core 231, and thus changing the rate of vapor production, meeting the needs of different users and improving the user experience of using the atomizer.

[0043] Reference Figure 2 and Figure 3 To further enhance the heating efficiency of the atomizing core 23, the atomizing core 23 uses a ceramic heating core 231. The ceramic heating core 231 has a honeycomb structure with good adsorption and thermal conductivity. The ceramic heating core 231 is cylindrical in shape and has a honeycomb structure inside. The ceramic heating core 231 can quickly adsorb and store the atomizing liquid. When the current is on, the ceramic heating core 231 can heat up rapidly to over 200 degrees Celsius, so that the atomizing liquid absorbed and stored in the ceramic core combines with the air and is quickly atomized into steam, which is then directed to the first air chamber.

[0044] Reference Figure 2 and Figure 3The ceramic heating core 231 is surrounded by a protective sleeve 7, which is made of stainless steel. The protective sleeve 7 has an oil guide hole 71. The ceramic heating core 231 is integrally formed with an oil guide protrusion 232 on its periphery. The oil guide protrusion 232 is embedded in the oil guide hole 71, and the surface of the oil guide protrusion 232 is in contact with the atomized liquid in the liquid storage chamber 24. Under the adsorption of the honeycomb ceramic heating core 231, the atomized liquid enters the ceramic heating core 231 for storage. At the same time, since the ceramic heating core 231 itself is made of brittle material, the protective sleeve 7 increases the toughness of the ceramic heating core 231, making the ceramic heating core 231 less prone to breakage, thereby extending the service life of the ceramic heating core 231.

[0045] The implementation principle of a uniformly heated electronic atomizer according to an embodiment of this application is as follows: When the electronic atomizer needs to adjust the temperature, air enters the atomizing section 2 from the air inlet 12. The battery 21 powers the main control board 22, which drives the atomizing core 23 to work and heat up the atomizing core 23, causing the atomizing liquid to heat and vaporize. Smoke is introduced from the atomizing core 23 into the smoke delivery section 3. The first temperature sensor 311 measures the temperature of the smoke and feeds back the initial temperature information to the main control board 22. The main control board 22 compares the initial temperature information with the preset taste temperature and controls the switching element 4 to open the straight pipe 33 or the spiral pipe 34 of the smoke delivery section 3. If smoke needs to be kept warm or heated, it is introduced into the straight pipe 33, and after heat compensation or preheating by the heating mesh 332, it is guided to the air outlet 11. If smoke needs to be cooled, it is introduced into the spiral pipe 34, and the smoke is guided through the side of the spiral pipe 34. The air entering through the ventilation holes 341 on the side wall of the smoke delivery section 3 exchanges heat with the smoke, cooling the smoke and guiding it to the outlet 11. At the end of the smoke delivery section 3 near the outlet 11, the second temperature sensor 312 measures the temperature of the smoke again and feeds back the end temperature information to the main control board 22. The main control board 22 compares the end temperature information with the preset taste temperature. If the result is that the temperature is insufficient or too high, the main control board 22 controls the micro cylinder 5 to drive the blocking plate 51 to block the outlet 11, and at the same time controls the heating element 32 to work to heat or cool the smoke in the smoke delivery section 3 until the temperature of the second temperature sensor 312 meets the requirements. Then, the main control board 22 controls the micro cylinder 5 to retract the blocking plate 51 and open the outlet 11. Finally, the smoke at a comfortable temperature is delivered to the user through the outlet 11, improving the user's experience of using the atomizer.

[0046] The dual temperature measurement by the first temperature sensor 311 and the second temperature sensor 312 is fed back to the main control board 22, which then drives the heating element 32 or the heating mesh 332 to heat the smoke in the smoke delivery section 3, or drives the switching element 4 to guide the smoke into the spiral pipe 34 for cooling, thus adjusting the smoke to the preset taste temperature. This makes the smoke temperature control more precise and improves the user's experience of using the atomizer.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
