The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, so that the technical solutions and the advantages thereof will be more clearly understood. It is to be understood that the drawings are provided for purposes of reference and illustration only and are not intended as a definition of the limits of the invention, but are shown in the drawing only and are not intended to be limiting.

Referring to fig. 1 and 2, an electrically heated atomizer 100 according to a first embodiment of the present invention includes an atomizer 10 and a battery pack 20 arranged axially opposite to each other.

The atomizer 10 is used to store a liquid, such as tobacco tar, and to heat the liquid to atomize it. Specifically, the atomizer 10 includes a liquid storage element 11 for storing liquid, a support member 12 provided inside the liquid storage element 11, a liquid absorbing element 13 fixed to the support member 12, a heating element 14 fixed to the liquid absorbing element 13, and a temperature sensing element 15.

The battery assembly 20 includes a battery 21 and a control circuit board 22 electrically connected. The battery 21 is used for power supply. The control circuit board 22 is electrically connected with the temperature sensing element 15 and the heating element 14 of the atomizer 10, and is used for controlling the operation of the temperature sensing element 15 and the heating element 14.

Referring to fig. 3 and 4, in particular, the liquid storage element 11 has a receiving cavity 111, and the supporting element 12 is disposed in the receiving cavity 111, dividing the receiving cavity 111 into a liquid storage cavity 1111 for storing liquid and an air flow channel 1112 for allowing air flow to pass through. The support 12 defines a bore 1211 that communicates with the reservoir 1111 and the air flow channel 1112. Liquid in the reservoir 1111 can flow from the channel 1211 into the gas flow channel 1112. The wicking element 13 is disposed in the air flow channel 1112 for absorbing liquid flowing in from the orifice 1211. The heating element 14 is disposed within the wicking element 13 for heating the absorbed liquid. The air flow channel 1112 of the temperature sensing element 15 is disposed on the wicking element 13 and spaced a predetermined distance from the heating element 14. In this embodiment, the temperature sensing element 15 is at least partially wrapped around the outer surface of the wicking element 13. Preferably, at least one end portion 151 of the temperature sensitive element 15 extends from said aperture 1211.

When the electric heating atomization device 100 of this embodiment operates, the liquid in the liquid storage chamber 1111 enters the support member 12 through the hole 1211, is absorbed by the liquid absorption element 13, and is heated and atomized by the heating element 14 fixed in the liquid absorption element 13. When the liquid in the liquid storage cavity 1111 is sufficient, the temperature sensing element 15 is submerged in the liquid, the temperature of the temperature sensing element 15 will not rise significantly, and the control circuit board 22 will not send an alarm signal. During the heating and atomizing process, the liquid in the liquid storage chamber 1111 is gradually reduced, and when the liquid is reduced to the temperature sensing element 15, the temperature sensing element is exposed. In the case of continued energization, the temperature of the temperature sensing element 15 rises, and the control circuit board 22 issues an alarm signal to prompt the user in advance that the liquid is about to be exhausted and that the liquid needs to be added. A small amount of liquid remains in the wicking element 13 so that continued heating of the heating element 14 will not cause dry burning, effectively avoiding the generation of burnt and harmful gaseous substances.

It should be noted that, the temperature sensing element 15 and the heating element 14 are spaced apart from each other by a predetermined distance, so that the heating element 14 and the temperature sensing element 15 are prevented from being in direct contact, thereby avoiding interference with the temperature sensing element 15. Preferably, the temperature sensing element 15 is located outside the heating element 14 in a radial direction of the reservoir element 11.

Preferably, the support seat 122 has a through hole 1221 penetrating in the axial direction. The axial top end of the liquid storage component 11 is provided with a suction port 113. A hollow air flow conduit 1131 extends from the suction port 113 toward the interior of the receiving chamber 111. The two axial ends of the supporting cylinder 121 are respectively connected to the bottom end of the air flow conduit 1131 and the through hole 1221. To define the air flow channel 1112. That is, the supporting member 12 and the air flow channel 1131 together divide the accommodating chamber 111 into a liquid storage chamber 1111 for storing liquid and an air flow channel 1112 for ventilation.

Specifically, the liquid storage element 11 is substantially hollow and cylindrical, and the suction port 113 is opened in the middle of the axial upper end of the liquid storage element 11 for the user to suck. The axial lower end of the liquid storage element 11 is an opening end. The cross section of the lower middle section of the liquid storage element 11 is approximately elliptical. The supporting seat 122 is disposed at a middle lower section of the liquid storage element 11. And is also approximately ellipsoidal so as to tightly abut against the inner wall of the liquid storage element 11 at the corresponding position of the lower middle section. The through hole 1221 is circular and located in the center of the supporting base 122. The support cylinder 121 is substantially cylindrical and is vertically connected to the support base 122. The inner diameter of the supporting cylinder 121 is not smaller than the diameter of the through hole 1221, and preferably, the inner diameter of the supporting cylinder 121 is equal to the diameter of the through hole 1221. So as to improve the air tightness between the supporting base 122 and the supporting cylinder 121.

Preferably, the resistance of the material constituting the temperature sensing element 15 changes as the temperature increases. In other words, the control circuit board 22 determines whether to send an alarm signal by detecting the resistance value of the temperature sensing element 15. For example, when the liquid is reduced to below the temperature sensing element 15, the resistance value of the temperature sensing element 15 is increased, and the control circuit board 22 detects that the resistance value of the temperature sensing element 15 is greater than the preset resistance value of the temperature sensing element 15, and then sends out an alarm signal. Preferably, the temperature sensing element 15 is made of a material such as nickel or stainless steel.

In this embodiment, the support cylinder 121 is generally cylindrical and the wicking element 13 mates with the support cylinder 121 and is correspondingly cylindrical, allowing gas to pass through the inner wall thereof.

In this embodiment, the heating element 14 is provided on the inner surface of the wicking element 13. Preferably, the heating element 14 is spirally attached to the inner surface of the heating element 14. The heating element 14 thus constructed has a large contact area with the liquid and is heated uniformly. It will be appreciated that in other embodiments, other curvilinear configurations may be used instead of the spiral configuration.

In this embodiment, referring to fig. 6 to 8, the temperature sensing element 15 includes a middle portion 152 and two end portions 151 connected to the middle portion 152, the middle portion 152 extends along the circumferential direction of the liquid absorbing member 13, and the two end portions 151 extend from the orifice 1211. Preferably, the middle portion 152 is embedded in the inner layer of the liquid absorbing member 13, and the two end portions 151 extend from the liquid absorbing member 13 and continue to the respective orifice 1211.

As shown in fig. 6, the present embodiment is further provided with a fixing portion 131 for fixing the temperature sensing element 15, and the fixing portion 131 is connected to the liquid absorbing element 13 and extends outward in the radial direction of the liquid absorbing element 13. The fixing portion 131 extends from the duct 1211. In this embodiment, there are two fixing portions 131, and correspondingly, two passages 1211 are also disposed on the supporting member 12, and the two end portions 151 of the temperature sensing element 15 are respectively fixed to the two fixing portions 131. In this embodiment, the two fixing portions 131 are symmetrically disposed with respect to the axis of the liquid absorbing member 13. Preferably, the fixing portion 131 is integrally formed with the liquid absorbing member 13.

It is understood that when there is only one of the passages 1211, there is one of the fixing portions 131. One end 151 of the temperature sensing element 15 is fixed to the fixing portion 131, and the other end 151 can be embedded in the liquid absorbing element 13. Preferably, the aperture 1211 of the present embodiment is a circular aperture 1211. The fixing portion 131 has a cylindrical shape. Preferably, the diameter of the duct 1211 corresponds to the diameter of the fixing portion 131, so that the fixing portion 131 with the end portion 151 fixed thereto is in close abutment with the inner wall of the duct 1211. It is understood that, in other alternative embodiments, the fixing portion 131 may have a shape such as a rectangular parallelepiped, a cylinder, etc., as long as the end portion 151 can be fixed.

The temperature sensing element 15 includes a middle portion 152 connected between two end portions 151, the middle portion 152 is preferably semi-circular, and extends and winds a half turn along the circumference of the liquid absorbing element 13, and the two end portions 151 extend from the two ends of the middle portion 152 in a direction away from each other, and are fixed to the two corresponding fixing portions 131.

Preferably, the two end portions 151 are spirally wound around the two corresponding fixing portions 131, respectively, so as to improve the effect of fixing the end portions 151 on the fixing portions 131. Preferably, the middle portion 152 is a semi-circular shape annularly disposed on the inner layer of the liquid absorbing element 13, and the two end portions 151 respectively extend from the two ends of the middle portion 152 in the radial direction away from each other and spirally wind around the fixing portion 131. It will be appreciated that in other embodiments, the middle section may have other shapes such as a wave shape, an S shape, etc., and the two end portions 151 may also extend in other directions such as an oblique upward direction, an oblique downward direction, etc., as long as the temperature sensing element 15 is spaced apart from the heating element 14 and the temperature sensing element 15 is spaced apart from the supporting seat 122. Therefore, when a certain amount of liquid remains in the liquid storage cavity 1111, the user can be warned in advance that the liquid is about to be exhausted, and the dry burning of the heating element 14 can be avoided.

In this embodiment, the sidewall of the supporting cylinder 121 is further opened with a liquid inlet 1213 located below the aperture 1211. The liquid inlet 1213 is located at one end of the support cylinder 121 close to the support base 122. It should be noted that, when the supporting cylinder 121 is provided with only the hole 1211, the temperature sensing element 15 protrudes from the hole 1211 together with the fixing portion 131 of the liquid absorbing element 13, so that the amount of liquid entering the supporting cylinder 121 from the hole 1211 is limited. When the liquid in the liquid storage cavity 1111 drops to the height of the duct 1211, the end 151 of the temperature sensing element 15 is exposed out of the liquid level, and an alarm is triggered to remind a user that the liquid storage amount is insufficient. Because a small amount of liquid remains in the liquid storage cavity 1111 at this time, atomization can still be supported for a period of time, and dry burning can be avoided. However, the liquid remaining in the liquid storage chamber 1111 cannot flow into the supporting cylinder 121 through the duct 1211, and therefore, an auxiliary liquid inlet 1213 is provided near the supporting seat 122 for allowing the remaining liquid to pass through and enter the supporting cylinder 121 to be atomized by the heating element 14, thereby avoiding dry burning.

Preferably, the outer diameter of the upper section 161 of the gland is larger than the outer diameter of the lower section of the gland, and the inner diameter of the upper section 161 of the gland is also larger than the inner diameter of the lower section of the gland, so that the inner wall at the junction of the upper section 161 and the lower section 162 forms a circular ring-shaped first abutment surface 1621. The sealing boot lower segment 162 is formed by extending the first abutting surface 1621 downward in the axial direction, and the sealing boot lower segment 162 has a second abutting surface 1622 opposite to the first abutting surface 1621 in the axial direction.

The two abutting surfaces abut against the supporting cylinder 121 and the air flow channel 1131 respectively under the action of elastic force. Preferably, the lower sealing boot section 162 completely covers the liquid absorbing member 13 in the radial direction, so as to prevent the upper axial surface of the liquid absorbing member 13 from being adhered by dust or the like. Preferably, the axially upper surface of the wicking element 13 is a torus that conforms to the two abutting surfaces.

Preferably, the insertion portion 1611 is formed by protruding from the outer surface of the lower section of the sealing sleeve in the radial direction, and in this embodiment, the insertion portion 1611 extends in the axial direction. It can be understood that, when the temperature sensing element 15 is fixed to the fixing portion 131, the insertion portion 1611 abuts against the fixing portion 131 and the temperature sensing element 15 fixed thereon. This arrangement can improve the stability of the connection of the support cylinder 121 and the first seal boot 16.

When the user sucks in the suction opening 113, the outside air enters the air inlet 171 of the base 17 through the air inlet hole 231 of the housing 23, and enters the support cylinder 121 through the through hole 1221 of the support base 122. At the same time, the wicking element 13 adsorbs the liquid and is heated by the heating element 14 to form a mist, which is mixed with air in the air flow channel 1112 and then re-directed to the suction port 113 via the air flow conduit 1131 for the user to inhale.

In this embodiment, the control circuit board 22 is connected with a microphone 26 as a switch. When the user sucks, the head 26 responds to trigger the corresponding module on the control circuit board 22 to operate, and the nebulizer 10 starts to operate. When the user stops sucking, the microphone 26 is closed, the corresponding module on the control circuit board 22 stops working, and the atomizer 10 stops working. The operation is convenient, and the user experience is good.

In this embodiment, the bracket 24 is formed with a cylindrical cavity 241 for receiving the microphone 26, a battery compartment 242 for receiving the battery, a plurality of posts 243 for fixing the control circuit board 22, a partition plate 244 for separating the battery from the control circuit board, and a charging port 245 corresponding to the charging socket 232.

Preferably, the nebulizer 10 in this embodiment further comprises a plug (not shown) inserted into the suction port 113 of the reservoir member 11. When the device is not in use, a plug may be inserted into the suction port 113 to seal off dust and the like from the outside. Preferably, the insertion end of the plug is concavely formed with a relief port so that the plug can be more easily inserted into the suction port 113.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
