Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarettes, and more specifically, particularly relates to a heating device for electronic cigarettes. Background Art

[0002] Electronic cigarettes are electronic products that imitate cigarettes. Although they do not contain tar, they still contain many other carcinogens and have the same appearance, smoke, taste and feel as cigarettes. Electronic cigarettes are mainly composed of four parts: smoke oil (containing nicotine, flavors, solvent propylene glycol, etc.), heating system, power supply and filter. They produce aerosols with specific smells for smokers to use through heating and atomization.

[0003] Based on the above, the inventors have found the following problems: most of the current electronic cigarette heating devices add the e-liquid directly into the device at one time, which is not convenient for controlling the amount of oil entering. At the same time, the current electronic cigarette heating devices are not convenient for monitoring the e-liquid level inside them. When there is too little e-liquid inside the heating device, the oil-conducting cotton core will burn dry during the subsequent heating process, causing the smoke to have a burnt smell, thus affecting the taste.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a heating device for an electronic cigarette is provided, in order to achieve the purpose of having more practical value. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a heating device for an electronic cigarette, comprising a main body 100 and an oil inlet mechanism 200, wherein the main body 100 comprises a heat-insulating tube 1001, wherein a flue 1003 is installed at the upper end of the heat-insulating tube 1001, and a PLC controller 1008 is installed at one side of the outside of the heat-insulating tube 1001, wherein the oil inlet mechanism 200 comprises a mounting block 2001 and an oil storage barrel 2006, wherein the mounting block 2001 is arranged at the inner bottom end of the heat-insulating tube 1001, wherein the oil storage barrel 2006 is arranged at one side of the outer wall of the heat-insulating tube 1001, wherein an oil storage ring 2003 is inserted into the interior of the mounting block 2001, wherein a liquid level sensor 2005 is installed at one side of the inner wall of the oil storage ring 2003, wherein a first connecting hole 2002 and a second connecting hole 2004 are respectively provided at one side of the outside of the mounting block 2001 and the oil storage ring 2003, wherein the first connecting hole 2002 and the ... A connecting pipe 2010 is inserted between the connecting holes 2004, a flow meter 2011 is sleeved on the outside of the connecting pipe 2010, and one end of the connecting pipe 2010 passes through the oil storage barrel 2006 and extends to the inside. A protective shell 2008 is installed at the bottom of the inside of the oil storage barrel 2006, and a micro pump 2009 is installed inside the protective shell 2008. By setting up a heat-insulating tube 1001, heat loss is avoided. By setting up the connecting pipe 2010, the smoke oil inside the oil storage barrel 2006 can enter the inside of the oil storage ring 2003 through the connecting pipe 2010. By setting up a liquid level sensor 2005, the oil level of the smoke oil inside the oil storage ring 2003 is monitored to avoid too little smoke oil inside the oil storage ring 2003 causing the oil guide cotton core 1007 to burn dry during the subsequent heating process. By setting up the flow meter 2011, the smoke oil flowing through the inside of the connecting pipe 2010 is measured, thereby achieving the purpose of quantitative oil intake.

[0026] Among them, the output end and the input end of the micro pump 2009 both extend through the protective shell 2008 to the outside, and the output end of the micro pump 2009 is connected to the connecting tube 2010. By setting the micro pump 2009, when the micro pump 2009 is started, the tobacco oil inside the oil storage barrel 2006 flows through the input end of the micro pump 2009 to the output end and then flows into the inside of the connecting tube 2010.

[0027] Among them, the micro pump 2009, the flow meter 2011 and the liquid level sensor 2005 are all electrically connected to the PLC controller 1008 through wires. By electrically connecting the micro pump 2009, the flow meter 2011 and the liquid level sensor 2005 to the PLC controller 1008, the minimum oil level of the smoke oil and the amount of smoke oil that needs to be quantitatively added can be input to the PLC controller 1008 first, and then the liquid level sensor 2005 monitors the oil level. When the minimum oil level is reached, the liquid level sensor 2005 sends a signal to the PLC controller 1008, and then the PLC controller 1008 controls the micro pump 2009 to work, so that the smoke oil flows into the oil storage ring 2003, and the flow meter 2011 monitors the amount of smoke oil. When the amount of smoke oil reaches a fixed value, the flow meter 2011 sends a signal to the PLC controller 1008, and the PLC controller 1008 controls the micro pump 2009 to close, thereby stopping the oil supply.

[0028] Among them, the oil storage barrel 2006 is embedded with an observation window 2007 on the side away from the thermal insulation tube 1001, and the upper end of the oil storage barrel 2006 is installed with an oil inlet pipe 2012, and the internal thread of the oil inlet pipe 2012 is connected with a plugging cover 2013. By setting the observation window 2007, it is convenient to observe the oil amount inside the oil storage barrel 2006 at any time. By setting the oil inlet pipe 2012, it is convenient to inject smoke oil. By setting the plugging cover 2013, the sealing performance of the oil storage barrel 2006 is improved.

[0029] Among them, a heating tube 1004 is installed at the bottom end of the flue 1003, and an electric heating wire 1005 is installed on the inner wall of the heating tube 1004. An oil-conducting cotton core 1007 is inserted at the bottom end of the heating tube 1004, and the bottom end of the oil-conducting cotton core 1007 extends to the inside of the oil storage ring 2003. By setting the oil-conducting cotton core 1007, the oil-conducting cotton core 1007 will absorb the smoke oil inside the oil storage ring 2003, which is convenient for heating the smoke oil through the electric heating wire 1005 to atomize the smoke oil.

[0030] Among them, a temperature sensor 1006 is installed at the upper end of the interior of the heating tube 1004. The temperature sensor 1006 and the electric heating wire 1005 are electrically connected to the PLC controller 1008 through wires. By connecting the temperature sensor 1006, the electric heating wire 1005 and the PLC controller 1008, the temperature sensor 1006 monitors the temperature inside the heating tube 1004 and transmits the signal to the PLC controller 1008. When the temperature is too high or too low, the electric heating wire 1005 can be controlled by the PLC controller 1008 to achieve temperature regulation.

[0031] Among them, a circular hole 1002 is provided at the upper end of the thermal insulation tube 1001, and the circular hole 1002, the flue 1003 and the heating tube 1004 are located on the same axis. By setting the circular hole 1002 and the flue 1003, the smoke generated by the heating of the tobacco oil inside the heating tube 1004 can float out from the circular hole 1002 through the flue 1003.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using this product, first check whether the internal mechanisms of the heating device of the electronic cigarette are complete. After ensuring that they are complete, first input the minimum oil level of the smoke oil and the amount of smoke oil that needs to be quantitatively added to the PLC controller 1008. When heating the smoke oil, by setting the oil guide cotton core 1007, the oil guide cotton core 1007 will absorb the smoke oil inside the oil storage ring 2003, so that the smoke oil is heated by the electric heating wire 1005 to atomize the smoke oil and float out from the round hole 1002 through the flue 1003. At the same time, the temperature sensor 1006 monitors the temperature inside the heating tube 1004 and transmits the signal to the PLC controller 1008. When the temperature is too high or too low, the electric heating wire 1005 can be controlled by the PLC controller 1008 to achieve temperature regulation. At the same time, the liquid level sensor 2005 monitors the oil level. When the lowest oil level is reached, the liquid level sensor 2005 sends a signal to the PLC controller 1008, and then the PLC controller 1008 controls the micro pump 2009 to work, so that the smoke oil inside the oil storage barrel 2006 flows through the input end of the micro pump 2009 to the output end and then flows into the inside of the connecting pipe 2010 until it enters the inside of the oil storage ring 2003. At this time, the flow meter 2011 set outside the connecting pipe 2010 monitors the amount of smoke oil. When the amount of smoke oil reaches a fixed value, the flow meter 2011 sends a signal to the PLC controller 1008, and the PLC controller 1008 controls the micro pump 2009 to close, thereby stopping the oil supply, thereby realizing quantitative oil supply, and monitoring the oil level to avoid too little smoke oil inside the oil storage ring 2003, which causes the oil guide cotton core 1007 to dry burn during the subsequent heating process.

[0034] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
