DETAILED DESCRIPTION

In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments are only used to explain the present application, rather than to limit the present application. In addition, it should be noted that, for the sake of ease of description, only partial structures related to the present application are shown in the accompanying drawings, rather than all structures.

The present application provides an electronic atomization device. Referring to Figures 1 to 6, the electronic atomization device 100 includes a mounting base 110, a heating element 120 and a battery 101. As shown, a liquid storage chamber 111 is defined in the mounting base 110. The liquid storage chamber 111 is used to store a liquid matrix. The liquid matrix may include, for example, one or more components such as glycerin, propylene glycol, nicotine preparations, flavors and fragrances, flavor additives, and other types of liquid matrix.

As shown in FIG5 , the heating element 120 is arranged on the mounting base 110, and the heating element 120 is used to heat the liquid matrix to generate an aerosol. The heating element 120 has a first side and a second side that are separated in the longitudinal direction. As shown in FIG5 , the first side is a liquid absorption surface 121, and the second side is an atomization surface 122. The atomization surface 122 is used to release the aerosol. A heating element such as a heating wire, a heating circuit or a heating film is arranged on the atomization surface 122, so that the liquid matrix can be atomized. The heating element 120 can be a porous member. As shown in FIG5 , the liquid absorption surface 121 is close to the liquid storage chamber 111 and contacts the liquid matrix in the liquid storage chamber 111. After the liquid absorption surface 121 contacts the liquid matrix in the liquid storage chamber 111, the liquid matrix flows from the liquid absorption surface 121 along the holes in the heating element 120 to the atomization surface, and is heated and atomized on the atomization surface 122. The atomization surface 122 heats the liquid matrix to generate an aerosol.

The battery 101 is arranged at intervals along the lateral direction on one side of the liquid storage chamber 111, and is used to power the heating element 120. In the embodiment of the present application, the lateral direction can be understood as the X direction shown in the drawings, the longitudinal direction can be understood as the Z direction shown in the drawings, and the thickness direction can be understood as the Y direction shown in the drawings. The Z direction, X direction, and Y direction shown in the drawings can also be understood as the up-down direction, left-right direction, and front-back direction of the electronic atomization device 100.

Referring to FIG5 , the electronic atomization device 100 further includes an air inlet duct 130 and an air outlet duct 140. The air inlet duct 130 serves as a channel for directing outside air to the atomization surface 122, and the air outlet duct 140 serves as a channel for outputting the atomized aerosol to the outside. In the embodiment of the present application, as shown in FIG3 and FIG5 , at least a portion of the air outlet duct 140 is disposed between the liquid storage chamber 111 and the battery 101. With such a design, after the user has finished inhaling, the residual heat of the battery 101 can be used to continue to heat the air outlet duct 140. The aerosol retained in the battery 101 can avoid or slow down the condensation of the aerosol in the outlet airway 140. The aerosol heated by the battery 101 can also be discharged outwardly in part, which alleviates the generation of condensate in the outlet airway 140. As shown in Figure 5, the heating element 120 has a first side and a second side relative to each other. The first side and the second side can be understood as the two sides of the heating element 120 in the horizontal direction (X direction) in Figure 5. The atomization surface is defined between the first side and the second side. The air inlet airway 130 is close to the first side, and the air outlet airway 140 is close to the second side. The air inlet airway 130 and the air outlet airway 140 are respectively located on both sides of the heating element 120. As shown by the dotted arrows in Figure 5, the airflow from the air inlet airway 130 flows from the first side to the second side and passes through the atomization surface 122, which makes the airflow from the air inlet airway 130 flow through the atomization surface 122 in parallel, and the airflow is relatively stable, which can take away more atomized aerosol.

At the same time, the air inlet duct 130 and the air outlet duct 140 are arranged on both sides of the heating element 120, so that the air outlet duct 140 is far away from the liquid storage chamber 111, so that there is no central air pipe in the liquid storage chamber 111, which will not affect the user's observation of the liquid matrix in the liquid storage chamber 111.

In one embodiment, as shown in FIG5 , the electronic atomization device 100 further includes a mounting seat 150. The mounting seat 150 is disposed on one side of the atomization surface 122 of the heating element 120. As shown in FIG5 , the mounting seat 150 is spaced apart from the atomization surface 122 of the heating element 120, thereby forming an atomization chamber 151 between the mounting seat 150 and the heating element 120. The heating element 120 is located above the atomization chamber 151, and the atomization chamber 151 provides an atomization space for the heating element 120. It is understandable that both the air inlet duct 130 and the air outlet duct 140 are connected to the atomization chamber 151. As shown in FIG5 , the air inlet airflow of the air inlet duct 130 enters from the left side of the atomization chamber 151, flows through the atomization surface 122 in parallel, takes away the atomized aerosol, and flows out from the air outlet duct 140 on the right side of the atomization chamber 151.

3 and 5 , the air inlet passage 130 is disposed on the mounting seat 150, and the air outlet passage 140 is disposed on the mounting base 110. No other components are required to form the air passage. In the embodiment of the present application, both the mounting base 110 and the mounting seat 150 can be made of plastic material, and corresponding air passages are formed on the mounting base 110 and the mounting seat 150 by means of integral injection molding.

In order to prevent the user from being unable to inhale the aerosol due to blockage of the air outlet duct 140, as shown in Figures 3 and 6, two air outlet ducts 140 can be provided. That is, the air outlet duct 140 includes a first air outlet duct and a second air outlet duct, and the first air outlet duct and the second air outlet duct extend in parallel within the mounting base. In this way, when one air outlet duct 140 is blocked, the other can still be used normally. The two air outlet ducts 140 extend along the Z direction. Of course, in other embodiments, a duct with a larger cross-section can also be directly provided to replace the two air outlet ducts 140 in this embodiment.

In conjunction with FIG. 5 and FIG. 8 , the mounting base 110 is further provided with a mounting cavity 112 and a battery cavity 113. The mounting cavity 112 and the liquid storage cavity 111 are arranged in sequence along the longitudinal direction, and the battery cavity 113 is located on one side of the mounting cavity 112 and the liquid storage cavity 111 along the transverse direction. It can also be said that the mounting cavity 112 is located below the liquid storage cavity 111, and the battery cavity 113 is located on the right side of the mounting cavity 112 and the liquid storage cavity 111. The mounting seat 150 is arranged in the mounting cavity 112, and the battery 101 is installed in the battery cavity 113.

As shown in FIG5 , an air hole 102 may be provided at the bottom of the electronic atomization device 100, and the air hole 102 connects the outside and the mounting cavity 112, so that the outside air enters the mounting cavity 112, and then the air flows to the atomization surface 122 through the air inlet duct 130 on the mounting seat 150 in the mounting cavity 112. The air hole 102 is provided at the bottom to make the appearance of the electronic atomization device 100 more beautiful.

FIG7 is a schematic diagram of the structure of an embodiment of the mounting base. As shown in FIG7 , a ventilation channel 1112 is provided on the mounting base 110. One end of the ventilation channel 1112 is connected to the liquid storage chamber 111, and the other end is connected to the atomization chamber 151. The ventilation channel 1112 is used to replenish gas into the liquid storage chamber 111 when the liquid matrix in the liquid storage chamber 111 flows out and causes negative pressure in the liquid storage chamber 111, so as to balance the pressure in the liquid storage chamber 111. As shown in FIG7 , a liquid outlet hole 1111 is also provided on the mounting base 110. Liquid outlet hole 1111 It is used to allow the liquid matrix in the liquid storage chamber 111 to flow to the heating element 120. One end of the liquid outlet 1111 is connected to the liquid storage chamber 111, and the other end extends to the heating element 120. In the embodiment of the present application, the port 1112a of the ventilation channel 1112 located in the liquid storage chamber is spaced apart from the liquid outlet 1111, that is, the ventilation port in the liquid storage chamber is far away from the liquid outlet 1111, so that the risk of ventilation bubbles blocking the liquid outlet 1111 can be reduced, ensuring that the liquid matrix is discharged from the liquid outlet 1111 normally, and preventing the heating element 120 from burning.

As shown in FIG. 7 , the port of the ventilation channel 1112 at one end of the liquid storage chamber 111 is disposed close to the inner wall of the liquid storage chamber 111 , so that the ventilation port can be as far away from the liquid outlet 1111 as possible.

In the embodiment of the present application, as shown in FIG9 , the electronic atomization device 100 further includes a flow guiding structure 152. The flow guiding structure 152 is used to guide the airflow to the heating element 120. Referring to FIG9 , the flow guiding structure 152 can be disposed on the mounting base 150. In other embodiments, the flow guiding structure 152 can also be a separately disposed structure, such as a separately disposed flow guiding plate.

Referring to FIG9 , the guide structure 152 includes a first guide wall 1521 and a second guide wall 1522. The first guide wall 1521 and the second guide wall 1522 are arranged opposite to each other along the width direction of the heating element, and the width direction is the Y direction shown in FIG9 . In other words, the first guide wall 1521 and the second guide wall 1522 are respectively located on both sides of the heating element 120 along the Y direction. The rear ends of the first guide wall 1521 and the second guide wall 1522 extend to the opposite side to gather the airflow. The "rear end" mentioned here refers to the rear end along the approximate flow direction of the airflow there. As shown in FIG9 , the rear end of the first guide wall 1521 extends toward the second guide wall 1522, and the rear end of the second guide wall 1522 extends toward the first guide wall 1521, so that the rear ends of the two guide walls are gathered, and the airflow is gathered to the heating element 120.

In one embodiment, as shown in FIG9 , in the embodiment of the present application, the guide structure 152 is disposed on the mounting seat 150. The first guide wall 1521 and the second guide wall 1522 are both arc-shaped. The front end of the first guide wall 1521 is connected to the front end of the second guide wall 1522, and the connection at least partially surrounds the mouth of the air inlet duct 130, thereby enveloping the airflow flowing in from the air inlet duct 130 to prevent airflow leakage. The rear end of the first guide wall 1521 and the rear end of the second guide wall 1522 are both gathered toward the center of the atomizing chamber 151 to guide the airflow to the center of the atomizing chamber 151, that is, to the atomizing surface 122, so that the airflow passing through the atomizing surface 122 is larger, and part of the airflow is prevented from flowing away without passing through the atomizing surface 122.

As shown in FIG9 , the end surface height of the first guide wall 1521 and the second guide wall 1522 at one end close to the heating element 120 in the longitudinal direction (Z direction) is higher than the end surface height of the inlet air duct 130 at one end close to the heating element 120 in the longitudinal direction. That is, the top of the first guide wall 1521 and the second guide wall 1522 is higher than the top of the inlet air duct 130, so that the first guide wall 1521 and the second guide wall 1522 have a better guiding effect. When the airflow comes out from the mouth of the inlet air duct 130, it is surrounded and guided away by the guide wall, so as to avoid the airflow from being too dispersed after coming out of the inlet air duct 130. Referring to FIG3 , the mounting base 110 has a first end a and a second end b that are opposite to each other in the longitudinal direction. As shown in FIG3 , the first end a of the mounting base 110 is provided with an open port 1113. The open port 1113 is connected to the liquid storage chamber 111, and the liquid storage chamber 111 is injected with liquid through the open port 1113.

In the finished product of the electronic atomization device 100 of the embodiment of the present application, the nozzle 160 is separated from the main body of the electronic atomization device 100, and the open opening 1113 at the top of the liquid storage chamber 111 is exposed to the outside. When in use, liquid is injected into the liquid storage chamber 111, and the nozzle 160 is snapped onto the mounting base 110 to complete the assembly and form an integral electronic atomization device 100.

Referring to FIG. 3 and FIG. 5 , the electronic atomization device 100 further includes a first sealing member 161. The first sealing member 161 is disposed at the opening 1113 and is used to seal the opening 1113. During assembly, after the liquid storage chamber 111 is filled with liquid, the first sealing member 161 is firstly covered on the opening 1113 on the liquid storage chamber 111 to seal the liquid storage chamber 111, and then the suction nozzle 160 is covered on the first end of the mounting base 110 and clamped. The suction nozzle 160 can press the first sealing member 161 to prevent the liquid storage chamber 111 from leaking.

As shown in FIG. 1 and FIG. 3 , the electronic atomization device 100 further includes a bottom cover 170 and a housing 180. The housing 180 is used to accommodate the mounting base 110. The bottom cover 170 is covered at the second end b of the mounting base 110. The housing 180 is sleeved around the mounting base 110. The nozzle 160, the housing 180 and the bottom cover 170 jointly define the outer surface of the electronic atomization device 100.

As shown in FIG. 4 , the bottom end of the battery cavity 113 on the mounting base 110 is open. After the battery 101 is installed in the battery cavity 113 , the bottom of the battery 101 is fixed by the bottom cover 170 .

Continuing to refer to FIG. 4 , one side of the battery cavity 113 can also be open, so that the side wall of the battery cavity 113 can be in a hoop shape, which can make the battery cavity 113 deformable to adapt to the size of the battery 101 and clamp the battery 101. In addition, it can save materials.

In the implementation of the present application, referring to FIG. 2 and FIG. 3 , the mounting seat 150 is connected to the mounting base 110 by snapping. A snap hole is provided on the wall surface of the mounting cavity 112 of the mounting base 110, and a snap protrusion is provided on the mounting seat 150. The snap protrusion snaps into the snap hole to fix the mounting seat 150 on the mounting base 110. As shown in FIG. 2 and FIG. 3 , the bottom cover 170 is snapped with the mounting seat 150. A snap buckle is provided at one end of the mounting seat 150 close to the base, and a snap hole is provided on the bottom cover 170.

As shown in FIG3 , in the embodiment of the present application, as shown in FIG3 , the mounting base 110 is at least partially configured as a transparent structure A, so that the liquid matrix in the liquid storage chamber 111 can be observed through the transparent structure A. At the same time, a window 181 corresponding to the transparent structure A can be provided on the housing 180. The transparent structure can be exposed, so that the liquid matrix in the liquid storage cavity 111 can be observed through the window 181 and the transparent structure. As shown in FIG3 , the transparent structure A can be arranged on at least one of the two sides of the mounting base 110 along its thickness direction (Y direction), that is, the transparent structure A can be arranged on the front side and/or the rear side of the mounting base 110. In the embodiment of the present application, since there is no central air pipe in the liquid storage cavity 111, when the liquid storage cavity is observed through the transparent structure A on the front side and/or the rear side of the mounting base 110, it will not be disturbed by the central air pipe, so the situation of the liquid matrix can be observed more clearly.

As shown in FIG5 , in the embodiment of the present application, the electronic atomization device 100 further includes a circuit board 190 and an airflow sensor 191. The circuit board 190 and the airflow sensor 191 are both mounted on the mounting seat 150. Thus, the mounting cavity 112 is used to accommodate the circuit board 190 and the airflow sensor 191. The airflow sensor 191 is connected to the circuit board 190, and the heating element 120 is also connected to the battery 101 through the circuit board 190. The airflow sensor 191 is used to detect the inhaled airflow. When the airflow sensor 191 detects the airflow, the circuit on the circuit board 190 is turned on, so that the heating element 120 is powered on.

Continuing to refer to FIG5, the mounting base 150 is provided with an airflow sensor mounting cavity 155 and an airflow channel 156. The airflow sensor mounting cavity 155 is used to mount the airflow sensor 191. The airflow channel 156 connects the airflow sensor mounting cavity 155 with the atomizing cavity 151. Referring to FIG5, one side of the airflow sensor 191 is connected to the outside atmosphere. As shown in FIG5, the other side of the airflow sensor 191 is enclosed in the airflow sensor mounting cavity 155, and the airflow sensor mounting cavity 155 is connected to the atomizing cavity 151. The airflow sensor mounting cavity 155 can be closed by a third sealing member 1551. When the user draws from the suction nozzle 160, a vacuum is formed in the atomizing cavity 151, that is, a vacuum is formed in the airflow sensor mounting cavity 155, so that an air pressure difference is generated on both sides of the airflow sensor 191, so that the airflow sensor 191 can realize the detection function.

More specifically, referring to Figures 3 and 5, an electrode column 153 is provided at one end of the mounting base 150 close to the heating element 120, and the electrode column 153 is connected to the circuit board 190. When the mounting base 150 is installed in the mounting cavity 112, the electrode column 153 contacts the heating element 120, so that the heating element 120 can be powered on.

As shown in FIG3 and FIG5 , the electronic atomization device 100 further includes a second sealing member 123. The second sealing member 123 is disposed between the mounting base 110 and the heating element 120 to seal the gap between the mounting base 110 and the heating element 120, thereby preventing the liquid matrix flowing out of the liquid outlet 1111 from leaking between the mounting base 110 and the heating element 120.

As shown in Fig. 3 and Fig. 5, the mounting seat 150 is provided with a fixing column 154, and the fixing column 154 is used to press against the second sealing member 123. Referring to Fig. 5, after the mounting seat 150 is installed in the mounting base 110, the fixing column 154 on the mounting seat 150 presses against the second sealing member 123, and the electrode column 153 on the mounting seat 150 presses against the heating element 120.
