[0041] Figure 1 and Figure 2 The atomizer in the first embodiment of the present invention is shown. The atomizer can form an electronic atomization device together with a battery device, and is used to provide atomization for liquid media such as cigarette liquid or liquid medicine. In this embodiment, the atomizer may include an atomizer seat 1 for mechanically and electrically connecting to the battery device, an atomizer assembly 2 installed in the atomizer seat 1, and a shell 3 sleeved on the atomizer seat 1. Among them, a liquid storage chamber 4 for storing liquid media is defined between the atomizer seat 1 and the shell 3. The atomizer assembly 2 is connected to the liquid storage chamber 4 in a liquid-conducting manner, and defines an atomizer chamber between the atomizer seat 1, and the atomizer chamber is used to mix the medium heated and atomized after the atomizer assembly 2 is powered on with the outside air.

[0042] Read also Figure 3 and Figure 4In this embodiment, the atomizer seat 1 includes a lower seat body 10 for mechanically and electrically connecting to the battery device, and an upper seat body 11 embedded on the top of the lower seat body 10, and the upper seat body 11 is used to carry the atomizer assembly 2. In this embodiment, an air inlet channel 100 connected to the outside is opened on the lower seat body 10. The lower seat body 10 includes a cylindrical seat body with an inner cavity, and the inner cavity is used to accommodate the lower part of the upper seat body 11. In this embodiment, the inner cavity of the lower seat body 10 is divided by a vertical partition 101, and the positive and negative electrode sheets that penetrate the bottom wall of the lower seat body 10 are respectively arranged on the two side walls of the partition 101, and the lower part of the upper seat body 11 has a cross-shaped groove. The first groove 119 is plug-fitted with the partition 101 to fix the upper seat body 11 on the lower seat body 10. The air inlet passage 100 may include a pair of air inlets opened on the side wall of the lower seat body 10 and a chamber formed between the second groove 120 and the inner cavity of the lower seat body 10 when the upper seat body 11 is embedded in the lower seat body 10 .

[0043] In this embodiment, the atomizer assembly 2 is supported in the upper seat body 11. The upper seat body 11 may be an inverted truncated cone with an inner cavity, and a supporting portion 121 for supporting the bottom edge of the atomizer assembly 2 is provided at the upper portion of the inner cavity of the upper seat body 11. In some embodiments, the upper seat body 11 may include a bottom wall 110, at least one air inlet hole 111 penetrating the bottom wall 110 near the edge, an airflow collection chamber 112 provided in the middle of the bottom wall 110 for collecting and guiding out a mixture of air and mist overflowing from the atomization surface, and a guide channel 113 extending from the air inlet hole 111 along the inner wall surface of the upper seat body 11 for a distance and then connected to the airflow collection chamber 112. Among them, the air inlet hole 111 is connected to the second groove 120 at the lower portion of the upper seat body 11, thereby connecting the air inlet channel 100.

[0044] like Figure 5 and Figure 6 As shown, in some embodiments, a section of arc-shaped wall 114 is provided on the bottom wall 110 of the upper body 11, extending from the inner wall surface of the upper body 11 along the air inlet 111 to the inner common tangent direction to the middle of the bottom wall, and a flow guide channel 113 is defined between the arc-shaped wall 114 and the inner wall surface of the upper body 11, and because the flow guide channel 113 corresponds to the atomizing surface of the atomizing assembly 2, the mist overflowing from the atomizing surface is mixed with the air from the outside through the flow guide channel 113, so the flow guide channel 113 forms the atomizing chamber of the atomizer. In addition, an airflow collection chamber 112 with a flow guide port 115 is formed between the arc-shaped wall 114 at the middle of the bottom wall, and the flow guide channel 113 is connected to the airflow collection chamber 112 through the flow guide port 115. In some embodiments, there is a gap between the arc-shaped wall 114 at the air inlet 111 and the atomizing surface, so that the atomizing surface and the arc-shaped wall 114 are not in contact with each other, thereby preventing the arc-shaped wall 114 from being in contact with each other and causing the arc-shaped wall 114 to be overheated.

[0045] In this embodiment, the upper body 11 includes two opposite air inlet holes 111 that penetrate the edge of the bottom wall 110, and two arc-shaped wall bodies 114 are formed from the inner wall surface of the upper body 11 along the inner common tangent direction of the air inlet holes 111 to the center circle of the bottom wall 110. The two arc-shaped wall bodies 114 and the inner wall surface of the upper body 11 define two flow guide channels 113, and the two arc-shaped wall bodies 114 form a cylindrical airflow collection chamber 112 with two opposite flow guide ports 115 around the center circumference of the bottom wall 110. In some embodiments, the upper body 11 is made of soft materials such as silicone, while the lower body 10 can be made of hard materials such as metal and plastic.

[0046] Read also Figure 2 and Figure 7 In this embodiment, the atomizer assembly 2 may include an atomizer core 20 supported in the upper seat body 11, a first air outlet channel 21 longitudinally penetrating the atomizer core 20, and a heating plate 22 disposed at the bottom of the atomizer core 20. In this embodiment, the first air outlet channel 21 in the atomizer core 20 is connected to the airflow collection chamber 112 for air conduction. The atomizer core 20 is an annular porous ceramic body supported on a supporting portion 121 at the upper part of the inner cavity of the upper seat body 11. An annular heating plate is disposed at the bottom of the atomizer core 20 that is not in contact with the upper seat body 11. The connecting pipe penetrates the bottom wall 110 of the upper seat body 11 and is electrically connected to the positive and negative electrodes on the lower seat body 10. The positive and negative electrodes are connected to an external power supply device to heat the heating plate and atomize the liquid medium at the bottom of the atomizer core 20, thereby forming an atomization surface.

[0047] As shown in the figure, in this embodiment, the shell 3 is sleeved on the upper seat body 11 and the lower seat body 10, and a liquid storage chamber 4 is defined between the shell 3 and the upper seat body 11, and the shell 3 and the lower seat body 10 are snap-fitted. In this embodiment, a buckle portion 118 is provided on the side wall of the lower seat body 10, which cooperates with the snap hole on the shell 3, so that the shell 3 is sleeved and fixed on the lower seat body 10. In addition, a second air outlet channel 30 is also provided in the shell 3, which is air-conductingly connected to the first air outlet channel 21 of the atomizer assembly 2, and the two form a complete air outlet channel. The smoke delivery channel of the present invention includes an air inlet channel 100, an air inlet hole 111, a guide channel 113, an airflow collection chamber 112, a first air outlet channel 21 and a second air outlet channel 30 that are connected in sequence.

[0048] In this embodiment, the atomizer may further include a seal 5, one end of which is embedded in the first air outlet channel 21 of the atomizer assembly 2, and abuts against the arc-shaped wall 114 at the middle of the bottom wall 110 of the upper seat body 11, that is, abuts against the arc-shaped wall 114 forming the airflow collection chamber 112, and is connected to the airflow collection chamber 112. The other end of the seal 5 is sleeved on the top of the atomizer core 20, and is plugged into the second air outlet channel 30 of the housing 3 for air-guiding connection, and defines a liquid suction groove 51 between the inner wall surface of the upper seat body 11, and the atomizer core 20 absorbs the liquid medium in the liquid storage chamber 4 through the liquid suction groove 51. In some embodiments, the seal 5 is a soft material.

[0049] By implementing the present invention, when a user inhales, air can enter from the air inlet 111, and after the airflow is guided by the guide channel 113 to flow along the atomization surface for a certain distance, the mixture of air and the mist overflowing from the atomization surface is collected in the airflow collection chamber 112, and then discharged, thereby bringing out the mist to the maximum extent, increasing the amount of smoke brought out by each puff of cigarette, and improving the smoker's satisfaction.

[0050] In addition, the present application guides the airflow to flow along the atomizing surface for a distance through the guide channel 113, fully mixes the air with the mist overflowing from the atomizing surface, collects it in the airflow collection chamber 112, and then guides it out. It can also minimize the formation of condensate, avoid users from inhaling condensate, and improve user experience.

[0051] In addition, in this embodiment, the atomizer includes a liquid storage chamber 4 for storing liquid, and a ventilation channel connecting the liquid storage chamber 4 with the outside world. The ventilation channel includes: an air inlet 63 connected to the outside world, a cavity 61 connected to the air inlet 63, and a ventilation groove 62 connecting the cavity 61 and the liquid storage chamber 4. The ventilation channel is used to connect the liquid storage chamber 4 with the outside world, replenish air to the liquid storage chamber 4, achieve gas-liquid balance, and make the liquid in the liquid storage chamber 4 flow more smoothly.

[0052] In some embodiments, the cavity 61 is ring-shaped or part of a ring-shaped shape, and the end of the cavity 61 close to the ventilation groove 62 has a capillary force. When the liquid in the liquid storage chamber 4 overflows into the cavity 61, the end of the cavity 61 close to the ventilation groove 62 locks the liquid through the capillary force, thereby achieving liquid locking in a standby state, and also achieving the recycling of the leaked liquid at the end of the cavity 61 close to the ventilation groove 62 in a suction state.

[0053] Furthermore, the atomizer further comprises an atomizing core 20, and the cavity 61 can be a closed loop or a one-segment or segmented ring, and the cavity 61 surrounds or partially surrounds the atomizing core 20, thereby making full use of the space. In this embodiment, the cavity 61 is a closed loop.

[0054] In this embodiment, the cavity 61 gradually narrows toward the ventilation groove 62, so that the end of the cavity 61 close to the ventilation groove 62 has a capillary force. In addition, preferably, the longitudinal cross section of the cavity 61 is in an inverted V shape.

[0055] The atomizer in this embodiment may include an atomizer seat 1 for mechanically and electrically connecting to the battery device, an atomizer assembly 2 installed in the atomizer seat 1, and a shell 3 sleeved on the atomizer seat 1. A liquid storage chamber 4 for storing liquid medium is defined between the atomizer seat 1 and the shell 3. The atomizer assembly 2 is connected to the liquid storage chamber 4 in a liquid-conducting manner, and defines an atomizer chamber between the atomizer seat 1, and the atomizer chamber is used to mix the medium heated and atomized after the atomizer assembly 2 is powered on with the outside air.

[0056] In this embodiment, the cavity 61 is surrounded by the inner wall of the housing 3 and part of the outer wall of the atomizer seat 1. In other embodiments, the cavity 61 can also be formed inside the atomizer seat 1, and the atomizer seat 1 and the housing 3 are closely connected to form an air inlet 63 connected to the cavity 61, and a ventilation groove 62 connected to the liquid storage chamber 4 is opened on the top of the atomizer seat 1.

[0057] Read also Figure 3 and Figure 4 In this embodiment, the atomizer seat 1 includes a lower seat body 10 for mechanically and electrically connecting with the battery device, and an upper seat body 11 embedded on the top of the lower seat body 10, and the upper seat body 11 is used to carry the atomizer assembly 2. The shell 3 is sleeved on the upper seat body 11 and the lower seat body 10, and the liquid storage chamber 4 and the ventilation channel are defined between the shell 3 and the upper seat body 11, and the shell 3 and the lower seat body 10 are snap-fitted.

[0058] like Figure 2 and 7 As shown, specifically, the upper seat body 11 includes an outer peripheral surface, the shell 3 includes an inner peripheral surface corresponding to the upper seat body 11, and the ventilation channel includes a cavity 61 defined by the outer peripheral surface of the upper seat body 11 and the inner peripheral surface of the shell 3, at least one ventilation groove 62 provided on the upper seat body 11 or the shell 3, and at least one air inlet 63 provided on the shell 3. Among them, the ventilation groove 62 is connected with the liquid storage chamber 4 and the cavity 61, and the air inlet 63 is connected with the cavity 61 and the outside.

[0059] When the user draws air, the air pressure inside the atomizing chamber is negative, and the air enters the atomizing chamber from the air inlet channel 100. The control circuit starts the heating plate to atomize the liquid medium adsorbed in the porous ceramic body. The liquid medium in the porous ceramic body is reduced, and under the action of capillary force, the porous ceramic body absorbs oil from the liquid storage chamber 4, and then continues to atomize. The liquid medium in the liquid storage chamber 4 is reduced, the gas space is increased, and the air pressure in the liquid storage chamber 4 is too negative. The air enters the cavity 61 from the air inlet 63 of the shell, and then enters the liquid storage chamber 4 through the ventilation groove 62, achieving gas-liquid balance, so that the speed of liquid down is adapted to the speed at which the liquid medium is atomized.

[0060] For example Figure 5 , Figure 6 and Figure 7 As shown, in the present embodiment, the upper portion of the upper seat body 11 includes an inverted frustoconical outer circumferential surface, the shell body 3 includes a cylindrical inner circumferential surface, and an annular boss 116 is provided in the middle portion of the upper seat body 11. The top of the inverted frustoconical outer circumferential surface and the outer circumferential surface of the annular boss 116 are respectively abutted against the cylindrical inner circumferential surface to form a cavity 61 which gradually narrows toward the ventilation groove 62, and whose longitudinal cross-section is narrow at the top and wide at the bottom.

[0061] Reference Figure 8a-8c Due to capillary force, the smoke liquid in the liquid storage chamber 4 entering the cavity 61 through the ventilation groove 62 will be adsorbed on the top of the inverted V shape, and thus stored in the cavity 61. When the user inhales, the liquid in the liquid storage chamber 4 decreases, the air pressure drops, and the smoke liquid adsorbed on the top of the inverted V shape will flow back from the ventilation groove 62 to the liquid storage chamber 4. This inverted V-shaped structural design can prevent the smoke liquid from flowing out of the shell on the one hand, and on the other hand, it can also allow the smoke liquid at the bottom of the cavity 61 to flow back to the liquid storage chamber 4 along the inverted V-shaped structure. Among them, Figure 8a-8c A in the figure is the amount of liquid adsorbed on the top of the inverted V-shape under different conditions, specifically:

[0062] Figure 8a When the liquid storage chamber 4 is in a standby state and the internal pressure is the same as the external pressure, the smoke oil forms an oil film at the ventilation groove 62 to generate tension, thereby locking the liquid and being in a vapor-liquid equilibrium state.

[0063] Figure 8b When the external environment changes in the standby state, for example, negative pressure appears, and the internal pressure of the liquid storage chamber 4 is greater than the external pressure, the smoke liquid further leaks from the ventilation groove 62 to the cavity 61. Since the cavity 61 is an inverted V-shaped structure, the smoke liquid is pulled by the maximum capillary force and tension at the top gap of the cavity 61, thereby achieving the liquid locking function. The capillary force and tension pull the smoke liquid less downward until the tension is cut off. At this time, a small part of the smoke liquid will be retained on the annular boss 116, and the annular boss 116 prevents the smoke liquid from flowing out of the air inlet 63.

[0064] Figure 8cWhen the inhalation state occurs, the liquid medium in the liquid storage chamber 4 decreases, the gas space increases, and the air pressure in the liquid storage chamber 4 becomes too negative. When the internal pressure of the liquid storage chamber 4 is less than the external pressure, the external pressure breaks through the tension of the smoke oil at the ventilation groove 62, allowing the external air to enter the liquid storage chamber 4, completing the ventilation operation. At the same time, the smoke oil adsorbed on the top of the inverted V shape can be squeezed back into the liquid storage chamber 4, thereby realizing the recycling of the leaked liquid.

[0065] In some embodiments, the ventilation groove 62 is provided on the upper seat 11 or the housing 3 at the junction of the top of the inverted truncated cone outer circumference and the cylindrical inner circumference. In this embodiment, the ventilation groove 62 is provided on the upper seat 11 at the junction of the top of the inverted truncated cone outer circumference and the cylindrical inner circumference. In addition, the depth of the ventilation groove 62 is gradually reduced toward the cavity 61, and the ventilation groove 62 is small enough to have capillary force. Preferably, the opening size of the top of the ventilation groove 62 is 1.0 mm*0.3 mm.

[0066] In some embodiments, the air inlet 63 and the ventilation groove 62 are arranged vertically and staggered in the circumferential direction. Preferably, in this embodiment, in order to further prevent the smoke liquid from flowing out of the air inlet 63, the air inlet 63 and the ventilation groove 62 are designed to be arranged opposite to each other in the circumferential direction. The liquid medium needs to flow a half-circle distance from the ventilation groove 62 to the air inlet 63, so the smoke liquid can be prevented from flowing out to the greatest extent.

[0067] In this embodiment, the atomizer further includes at least one snap hole provided on the housing 3, at least one snap-fit ​​portion 118 provided on the atomizer seat 1 and snap-fitted with the snap hole, and a ventilation channel connected to the liquid storage chamber 4; the ventilation channel is also connected to the outside world through at least one snap hole. Moreover, an air intake gap may be formed between the snap hole and the snap-fit ​​portion 118, and the ventilation channel is connected to the outside world through the air intake gap. In other embodiments, a hole may be opened at the snap-fit ​​portion 118 as an air intake hole 111, and the ventilation channel is connected to the outside world through the air intake hole 111.

[0068] In the present invention, the card hole can be used as the air inlet 63 of the ventilation channel, thereby reducing the number of holes opened on the shell, improving the aesthetics, and enhancing the user experience.

[0069] When the housing 3 is sleeved on the lower seat 10, the buckle portion 118 of the lower seat 10 is snapped on the air inlet 63 to form an air inlet gap, which is connected to the cavity 61. In addition, in this embodiment, when the annular boss 116 is opposite to the air inlet 63, an air inlet groove 117 connected to the cavity 61 may be provided at the annular boss 116, and the air inlet groove 117 is connected to the air inlet 63 or the air inlet gap.

[0070] The present invention designs a ventilation channel, including: an air inlet 63, which is connected to the outside world; a cavity 61, which is connected to the air inlet 63; and a ventilation groove 62, which connects the cavity 61 and the liquid storage cavity 4, so as to connect the liquid storage cavity 4 with the outside world, replenish air for the liquid storage cavity 4, achieve gas-liquid balance, and make the liquid in the liquid storage cavity 4 more unobstructed. In addition, the cavity 61 is annular or a part of annular, and one end of the cavity 61 close to the ventilation groove 62 has a capillary force, which simultaneously realizes the locking of liquid in the standby state and the recovery of leaked liquid in the suction state.

[0071] In the second embodiment, the present invention further constructs an electronic atomization device in which an atomizer and a battery device are integrated. All the above embodiments are applicable to the embodiments of the integrated electronic atomization device. The electronic atomization device includes all the above implementation methods of the atomizer, which will not be repeated here.

In addition, various modifications may be made to the present invention for specific situations or specific circumstances without departing from the scope of the present invention.
