Detailed Description

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 illustration and description only and are not intended as a definition of the limits of the invention, but the dimensions shown in the drawings are for convenience and are not to be taken as limiting the scale.

Referring to fig. 1 and 2, an electrically heated atomizer according to a first embodiment of the present invention includes an atomizer 10 and a battery pack 20 arranged axially opposite to each other. Preferably, the atomizer 10 is plugged into the battery assembly 20 and is fixedly connected to the battery assembly 20 by a magnet, which will be described in detail below.

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 reservoir member 30 for storing a liquid, a liquid absorbing member 40 fixed in the reservoir member 30 for absorbing the liquid, a heating member 50 fixed to the liquid absorbing member 40 for heating the absorbed liquid, and a temperature sensing member 60 fixed to the liquid absorbing member 40. In particular, the temperature sensing elements 60 are positioned above the heating element 50 in an axial direction of the reservoir element 30 and are spaced apart from each other by a predetermined distance such that liquid in the reservoir element 30 flows past the temperature sensing elements 60 and then toward the heating element 50.

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 to the temperature sensing element 60 and the heating element 50 of the atomizer 10, and is used for controlling the operation of the temperature sensing element 60 and the heating element 50.

In the heating atomization process of the electric heating atomization device of the embodiment, the tobacco tar in the liquid storage element 30 gradually decreases. When the tobacco tar floods the temperature sensing element 60, the temperature of the temperature sensing element 60 does not rise significantly and the control circuit board 22 does not issue an alarm signal. When the soot is reduced below the temperature sensing element 60, the temperature sensing element 60 is exposed. With continued power, the temperature sensing element 60 increases in temperature and the control circuit board 22 sends an alarm signal to prompt the user in advance that the tar is about to be depleted and that the tar needs to be added. At this time, since a small amount of smoke remains in the liquid absorbing member 40, the heating member 50 will not be burned, and the generation of burnt smell and harmful gas substances can be effectively avoided.

Referring to fig. 2 to 4, preferably, the liquid absorbing member 40 is made of one or more of ceramics, microporous ceramics, and diatomaceous earth, and includes axially upper and lower surfaces 41 and 42 opposed in the axial direction of the liquid storage member 30, and a liquid containing groove 43 recessed from the axially upper surface 41 toward the axially lower surface 42. Preferably, the temperature sensing element 60 is flush with the axially upper surface 41 of the wicking element 40. Preferably, the heating element 50 is located on the axially lower surface 42 of the wicking element 40. When the smoke oil is reduced to the lower part of the temperature sensing element 60, because part of the smoke oil is accumulated in the liquid containing groove 43, the heating element 50 will not be burnt, and the generation of burnt smell and harmful gas substances can be effectively avoided. Preferably, the cross section of the opening of the liquid containing groove 43 is gradually reduced from top to bottom, and the heating element 50 corresponds to the position right below the liquid containing groove 43, which is beneficial to gathering tobacco tar to the heating element 50.

Preferably, the resistance of the material constituting the temperature sensing element 60 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 60. For example, when the smoke oil is reduced to below the temperature sensing element 60, the resistance value of the temperature sensing element 60 is increased, and the control circuit board 22 detects that the resistance value of the temperature sensing element 60 is greater than the preset resistance value of the temperature sensing element 60, and then sends out an alarm signal. Preferably, the temperature sensing element 60 is made of a material such as nickel or stainless steel. In this embodiment, the temperature sensing element 60 is in the shape of a long strip. Both ends of the temperature sensing element 60 are connected to the control circuit board 22 through first pins 61, respectively. Preferably, said first leg 61 is at least partially embedded in the wicking element 40 to improve the fixing effect of the temperature sensing element 60 on the wicking element 40. As shown, the first lead 61 in this embodiment is bent and includes a first horizontal section 610 and a second vertical section 611 connected vertically, wherein the first horizontal section 610 is connected to one end of the temperature sensing element 60, and the second vertical section 611 penetrates the wicking element 40 to be connected to the control circuit board 22.

Preferably, the heating element 50 is substantially wave-shaped and includes a plurality of elongated body portions 51 arranged at intervals, and a plurality of connecting portions 52 connecting the body portions 51 end to end. The heating element 50 thus constructed has a large contact area with the soot and heats uniformly. It will be appreciated that in other embodiments, the main body 51 and the connecting portion 52 may have a curved configuration instead of a long strip configuration. For example, one body portion 51 and the connection portions 52 connected to both ends thereof together form an S-shaped configuration and are cyclically reciprocated thereby to form the wavy heating element 50. More preferably, the heating element 50 is formed with a plurality of micro-holes 53 through its thickness. The arrangement of the plurality of micro holes 53 may be adapted as desired, and the illustrated arrangement of micro holes 53 is shown as an example only. The plurality of micro-holes 53 increase the contact area of the soot with the heating element 50, thereby increasing the atomization area and providing more uniform heating. In this embodiment, both ends of the heating element 50 are connected to the control circuit board 22 through second pins 54, which are preferably long rod-shaped, respectively.

The heating element 50 is made of an electrically conductive material, and may include, for example, one or more of nickel, nickel foam, steel, nichrome, iron-chromium-aluminum alloy, and titanium. Preferably, the wicking element 40 and the heating element 50 are integrally formed by die casting and sintering. Specifically, the heating element 50 may be fixed in the mold cavity, one or more of ceramic, microporous ceramic, and diatomite may be die-cast into the mold cavity, and the die-cast heating element 50 and the liquid absorbing element 40 may be sintered to form an integral structure. Alternatively, the heating element 50 may be formed on the axially lower surface 42 of the liquid absorbing element 40 by thick film printing or silk screening. Specifically, the liquid absorbing member 40 made of ceramic may be used as a substrate, and the material of the heating element 50, for example, a conductor such as nickel, may be printed on the axially lower surface 42 of the liquid absorbing member 40 by screen printing.

Referring to fig. 2, 5 and 6, the atomizer 10 of the present embodiment further includes a mounting bracket 70 for securing the wicking element 40 within the reservoir element 30. In this embodiment, the liquid storage element 30 is substantially cylindrical with one open end and one closed end. The connecting frame 70 is fixed to a substantially central portion of the interior of the liquid storage member 30 to divide the cavity of the interior of the liquid storage member 30 into a liquid storage chamber 31 for storing liquid and an air inlet chamber 32 for introducing air.

Specifically, the connecting frame 70 includes a base portion 71 having a substantially hollow cylindrical shape, and a bridge portion 72 connected between opposite inner sides of the base portion 71. The upper section of base 71 and the corresponding bridge 72 enclose two spaced drainage lumens 710, and the lower section of base 71 is adapted to receive the wicking element 40. The top end of the liquid guide cavity 710 is communicated with the liquid storage cavity 31, and the bottom end of the liquid guide cavity 710 is communicated with the liquid containing groove 43 of the liquid absorbing element 40.

The bridge portion 72 is shaped like a hollow rectangular parallelepiped, and two ends thereof respectively penetrate through two opposite side walls of the base portion 71 and are integrally connected to form a transverse channel 720. Preferably, two opposite side walls of the lower section of the base 71 are also recessed to form a vertical channel 711, respectively, the vertical channel 711 extending from a corresponding end of the transverse channel 720 to a corresponding axial bottom end of the through base 71. Thus, the transverse channel 720 and the vertical channels 711 at both ends thereof together form an inverted U-shaped channel. The U-shaped channel communicates with the inlet chamber 32. In this embodiment, a through air hole 721 is formed on the top wall of the bridging portion 72. The reservoir member 30 has an exhaust tube 33 positioned within the reservoir chamber 31. The vent hole 721 communicates with the exhaust pipe 33, and therefore, the air in the intake chamber 32 can be discharged into the exhaust pipe 33 through the inverted U-shaped passage, the vent hole 721.

Preferably, the atomizer 10 in the present embodiment further includes a plug 34 inserted into an exhaust port (i.e., an axially upper end) of the exhaust pipe 33. When the device is not in use, a plug 34 is inserted into the exhaust port of the exhaust pipe 33 to isolate dust from the outside. Preferably, the insertion end of the plug 34 is recessed to form a relief opening 340 so that the plug 34 can be more easily inserted into the exhaust pipe 33.

To improve the seal between the attachment frame 70 and the wicking member 40, a first generally annular sealing boot 73 can also be disposed between the wicking member 40 and the attachment frame 70. Similarly, to improve the seal between the attachment frame 70 and the reservoir member 30, a second generally annular sealing boot 74 may be disposed between the attachment frame 70 and the reservoir member 30.

In this embodiment, the atomizer 10 further includes a base 80 fixed to the open end of the reservoir member 30, and two first electrodes 81 and two second electrodes 82 fixed to the base 80. In this embodiment, the base 80 is substantially ellipsoidal, and two engaging portions 83 facing each other are formed on the outer peripheral wall thereof. The liquid storage element 30 has a bayonet 35 formed corresponding to the engagement portion 83. When the base 80 is inserted into the liquid storage element 30, the engaging portion 83 engages with the bayonet 35, thereby fixing the base 80 to the liquid storage element 30. The base 80 is formed at its middle with an air inlet 84 extending axially therethrough. The intake port 84 communicates with the intake chamber 32. Two second electrodes 82 are respectively inserted into two opposite sides of the air inlet 84. The two first electrodes 81 are respectively inserted on both sides of the two second electrodes 82. The aforementioned first pins 61 connected to the temperature sensing element 60 are inserted into the corresponding first electrodes 81, and the second pins 54 connected to the heating element 50 are inserted into the corresponding second electrodes 82. Preferably, two first magnets 85 respectively located at two sides of the two first electrodes 81 are further fixed in the base 80.

Referring to fig. 2 and 7, the battery pack 20 of the present embodiment includes a cylindrical housing 23 having an open end and a closed end, a hollow bracket 24 accommodated in the housing 23 and having a substantially semi-cylindrical shape, and the battery 21 and the control circuit board 22 fixed in the bracket 24. Preferably, two second magnets 240 corresponding to the two first magnets 85, respectively, are also fixed to the axial top end of the bracket 24. When the assembled nebulizer 10 is inserted into the assembled battery pack 20, the first magnet 85 and the second magnet 240 attract each other, thereby fastening the nebulizer 10 and the battery pack 20 together. It is also preferable that the second magnet 240 slightly protrudes from the axial top end of the bracket 24 to form an air inlet gap 25 between the base 80 and the bracket 24, and the housing 23 is formed with an air inlet hole 230 penetrating through a sidewall thereof corresponding to the air inlet gap 25.

When a user sucks on the air outlet of the air discharge pipe 33, the external air enters the air inlet gap 25 through the air inlet hole 230 of the housing 23 and then enters the air inlet chamber 32 through the air inlet 84 of the base 80. At the same time, the wicking element 40 adsorbs the tobacco smoke and is heated by the heating element 50 to form a vapor that mixes with air in the intake chamber 32 and then enters the exhaust tubing 33 via the inverted U-shaped channel of the attachment frame 70, the vent 721, for ingestion by the user.

In this embodiment, the battery assembly 20 further includes a plurality of pogo pins 26 corresponding to the first electrode 81 and the second electrode 82. After the atomizer 10 is inserted into the battery pack 20, one end of the electrode abuts against the top end of the elastic needle 26, so that the electrode is electrically connected with the elastic needle 26. The bottom end of the bullet pin 26 is electrically connected to the control circuit board 22 by a wire or the like. In other words, the temperature sensing element 60 is electrically connected to the control circuit board 22 through the first pin 61, the first electrode 81, and the corresponding pogo pin 26. The heating element 50 is electrically connected to the control circuit board 22 through the second pin 54, the second electrode 82, and the corresponding pogo pin 26.

In this embodiment, the elastic needle 26 includes a sleeve 260 fixed in the base 80, a core shaft 261 movably accommodated in the sleeve 260, and a spring 262 abutting against between the core shaft 261 and the sleeve 260. When the electrode abuts against the mandrel 261, the mandrel 261 moves in the sleeve 260 and abuts against the electrode under the support of the spring 262, thereby achieving stable connection of the electrode and the elastic needle 26.

In this embodiment, the control circuit board 22 is connected with a microphone 27 as a switch. When the user sucks, the microphone 27 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 27 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 27 and a plurality of first posts 242 for fixing the control circuit board 22. Preferably, the bracket 24 in this embodiment further includes a fixing block 28 for fixing the control circuit board 22, and the fixing block 28 is formed with a plurality of second insertion posts 280. During assembly, after the control circuit board 22 with the microphone 27 is inserted into the first plug 242, the second plug 280 of the fixing block 28 penetrates the control circuit board 22 to be inserted into the bracket 24, so as to fixedly connect the control circuit board 22 to the bracket 24.

In addition, the first leads 161 in this embodiment are no longer embedded within the wicking element 40, but are inserted directly into the corresponding first electrodes 81. In this embodiment, the temperature sensing element 160 is spaced a greater distance axially from the heating element 50 on the axially lower surface 42 of the wicking element 40, and when the soot falls below the temperature sensing element 160 and the temperature sensing element 160 is exposed, the temperature of the temperature sensing element 160 will rise and the resistance will increase, and the control circuit board 22 will send an alarm signal in advance to prompt the user that the soot is about to be exhausted.

Referring to fig. 9A and 9B, the electric heating atomizer according to the third embodiment of the present invention is similar to the electric heating atomizer according to the first embodiment, and the same parts are not repeated herein. The electric atomizing device of the third embodiment of the present invention is different from the electric atomizing device of the first embodiment mainly in the construction of the heating element and the liquid absorbing element.

Specifically, the axially lower surface 142 of the liquid absorbing member 140 of the electrically heated atomizing device of the present embodiment is recessed to form a recess 141, so that a wall 143 enclosing the recess 141 is formed on the axially lower surface 142 of the liquid absorbing member 140. Preferably, the heating element 150, which is wave-shaped as a whole, is located in the groove 141, and both ends of the heating element 150 in the width direction extend into the enclosing wall 143, respectively, so as to improve the connection stability of the heating element 150 and the wicking element 140.

Referring to fig. 10A and 10B, an electric heating atomizer according to a fourth embodiment of the present invention is similar to the electric heating atomizer according to the first embodiment, and the same parts are not repeated herein. The electric atomizing device of the fourth embodiment is different from the electric atomizing device of the first embodiment in the structure of the atomizer.

Specifically, the atomizer 110 of the electrically heated atomizing device in the present embodiment includes a liquid storage element (not shown) for storing liquid, and an atomizing core accommodated in the liquid storage element.

Preferably, the pouch 111 has at least one first inlet opening 113 formed through its sidewall and diametrically opposed to the wicking element 440. The adjusting sleeve 112 is formed with at least one second inlet hole 114 corresponding to the at least one first inlet hole 113 through a sidewall thereof. The adjusting sleeve 112 can rotate relative to the fixing sleeve 111, so that the coincidence degree of the first liquid inlet hole 113 and the second liquid inlet hole 114 is changed, and the liquid flow rate of the liquid in the liquid storage element entering the liquid suction element 440 through the first liquid inlet hole 113 and the second liquid inlet hole 114 is adjusted. For example, when the first fluid inlet port 113 is fully aligned with the second fluid inlet port 114, the flow of fluid from the fluid reservoir member into the wicking member 440 is maximized. It should be noted that the atomizing core in this embodiment is adapted to adjust the overlapping degree of the first liquid inlet 113 and the second liquid inlet 114 before the liquid storage element is installed. When the adjusting sleeve 112 is rotated to the required liquid flow rate, the atomizing core is then installed in the liquid storage element.

Four electrodes 582 are fixed in the base 580, wherein two pins 552 of the heating element 550 are respectively abutted with the axial top ends of two of the electrodes 582, and two pins 563 of the temperature sensing element 560 are respectively abutted with the axial top ends of the other two electrodes 582. Preferably, the pins 552 of the heating element 550 are bent, for example, 90 degrees, to improve the stability of the electrical connection with the corresponding electrodes 582. Similarly, the two pins 563 of the temperature sensing element 560 are also bent, for example, by 90 degrees, to improve the stability of the electrical connection with the corresponding electrodes 582. The axially lower ends of the four electrodes 582 abut against the top ends of the corresponding pogo pins 26 of the battery assembly 20, and the pogo pins 26 are connected to the control circuit board. Accordingly, the temperature sensing element 560 and the heating element 550 are electrically connected to the control circuit board via the corresponding electrodes 582 and pogo pins 26, respectively. The corresponding structure of the latch 26 can refer to the first embodiment, and is not described herein.

Referring to fig. 11 and 11D, the atomizer of the present embodiment further preferably includes a sealing member 590 disposed between the bottom plate 571 of the supporting cylinder 572 and the base 580, so as to improve the sealing property and prevent the liquid in the reservoir 531 from overflowing.
