[0040] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0042] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic atomization device according to one embodiment of the present application. In this embodiment, an electronic atomization device 100 is provided. The electronic atomization device 100 can be used to heat and atomize a herbal medicine to form an atomized gas for inhalation by the user, thereby allowing the herbal medicine to be deposited in the desired area of the patient, achieving a medical and healthcare effect.

[0043] Specifically, the electronic atomization device 100 includes an atomizer 10 and a main unit 20. The atomizer 10 and main unit 20 are detachably connected. The atomizer 10 heats and atomizes the herbal medicine when powered. The main unit 20 includes a power supply assembly. The atomizer 10 plugs into a port on one end of the main unit 20 and connects to the power supply assembly within the main unit 20, which then supplies power to the atomizer 10. When the atomizer 10 needs to be replaced, it can be removed and a new one installed on the main unit 20, allowing the main unit 20 to be reused.

[0044] Of course, the electronic atomization device 100 also includes other components in the existing electronic atomization device, such as a microphone, a bracket, etc. The specific structures and functions of these components are the same as or similar to those in the prior art. Please refer to the prior art for details and will not be repeated here.

[0045] The specific structure and function of the atomizer 10 may refer to the detailed description of the atomizer 10 in the following embodiments.

[0046] See also Figures 2 to 4b ,in, Figure 2 A schematic diagram of the overall structure of an atomizer provided in one embodiment of the present application; Figure 3 for Figure 1 a disassembled schematic diagram of the structure shown; Figure 4a Provided for an embodiment of this application Figure 1 AA sectional view of the structure shown; Figure 4b Another embodiment of the present application provides Figure 1 AA sectional view of the structure shown; in this embodiment, a nebulizer 10 is provided, which can be used to atomize herbal medicines to atomize the herbal medicines to form atomized gas for the user to inhale, so that the herbal medicines can be deposited on the desired part of the patient to achieve the effect of medical care.

[0047] Specifically, the atomizer 10 includes a housing 11, a mounting base 12, and an atomizing core 13. The mounting base 12 cooperates with the housing 11 to form a liquid storage chamber for storing herbal medicine. A liquid discharge hole 1211 is formed on the mounting base 12, communicating with the liquid storage chamber to allow the herbal medicine in the liquid storage chamber to flow out through the liquid discharge hole 1211. A blocking portion 1212 is provided on the wall of the liquid discharge hole 1211 to disrupt the surface tension of the herbal medicine flowing through the liquid discharge hole 1211, thereby preventing the formation of bubbles during the flow of the herbal medicine through the liquid discharge hole 1211. This, in turn, prevents the formation of bubbles during the gas-liquid circulation process, which could lead to poor liquid discharge.

[0048] Among them, the mounting seat 12 may specifically include a first seat body 121 and a second seat body 122; the first seat body 121 cooperates with the shell 11 to form a liquid storage chamber, which is used to accommodate herbal medicine; the first seat body 121 is arranged on the second seat body 122, and cooperates with the second seat body 122 to form an atomization chamber; specifically, the lower liquid hole 1211 is specifically opened on the first seat body 121, and the lower liquid hole 1211 has a liquid inlet 1211a and a liquid outlet 1211b. Specifically, the liquid inlet 1211a of the lower liquid hole 1211 is opposite to and connected to the liquid storage chamber, and the liquid outlet 1211b is opposite to and connected to the atomization chamber, so that when the herbal medicine needs to be atomized, the herbal medicine in the liquid storage chamber can enter the atomization chamber from the lower liquid hole 1211.

[0049] For details, see Figure 5 and Figure 6 ,in, Figure 5 A schematic structural diagram of a first seat provided in a first perspective according to an embodiment of the present application; Figure 6 This is a schematic structural diagram of the first seat under the second visual perspective provided by an embodiment of the present application; in one embodiment, the blocking portion 1212 may specifically be a blocking plate, which may be specifically arranged at a position close to the atomizer core 13 of the lower liquid hole 1211 and partially block the lower liquid hole 1211 along the radial direction of the lower liquid hole 1211; specifically, the area of the blocking plate may be larger than half of the cross-sectional area of the lower liquid hole 1211, so as to reduce the water flow cross-section of the lower liquid hole at the position corresponding to the blocking plate, thereby minimizing the probability of bubble formation.

[0050] In one specific embodiment, the blocking plate is specifically arranged at the position where the liquid outlet 1211b of the lower liquid hole 1211 is located to prevent the herbal medicine from forming bubbles at the position where the liquid outlet 1211b of the lower liquid hole 1211 is located, thereby blocking the lower liquid hole 1211 and causing the problem of poor liquid discharge. The following embodiments all take this as an example.

[0051] In one embodiment, see Figure 5 and Figure 6 The first base body 121 is an annular structure, and a mounting portion 1213 is formed on the first base body 121. The mounting portion 1213 and the inner side wall of the first base body 121 define two lower liquid holes 1211. A blocking portion 1212 is provided on the hole wall of each lower liquid hole 1211. The blocking portion 1212 is specifically provided on the inner side wall of the lower liquid hole 1211 away from the outer side wall of the mounting portion 1213. The blocking portion 1212 defines a liquid outlet 1211b with the outer side wall of the mounting portion 1213 for the herbal medicine to pass through. For details, see Figure 6 The blocking portion 1212 may also be arranged along the inner wall of the first seat body 121 and cooperate with the outer wall of the mounting portion 1213 to define and form two liquid outlets 1211b. The following embodiments take this as an example.

[0052] To reduce the adhesion of the herbal medicine to the surface of the barrier 1212, the upper surface of the barrier 1212 in contact with the herbal medicine is preferably roughened. This reduces the adhesion of the herbal medicine to the barrier 1212, thereby facilitating the herbal medicine's dispensing. This allows airflow between the herbal medicine and the barrier surface, preventing the formation of a vacuum and a tight fit that could hinder dispensing. In practice, the roughened surface can be formed using a sun-texturing process.

[0053] Specifically, in order to reduce the resistance of the blocking plate to the downward flow of the herbal medicine as much as possible, the extension direction of the blocking plate can be tilted toward the downward flow direction of the herbal medicine, that is, the blocking plate is tilted in the direction away from the liquid storage chamber, so as to facilitate the flow of the herbal medicine to the atomization chamber; specifically, the side surface of the blocking portion 1212 facing the liquid storage chamber has a first edge portion and a second edge portion that are relatively arranged; wherein the first edge portion is connected to the inner side wall of the downward liquid hole 1211, and the second edge portion extends toward the mounting portion 1213, and is defined with the outer side wall of the mounting portion 1213 to form a liquid outlet 1211b; in a specific embodiment, the straight-line distance between the first edge portion and the liquid inlet 1211a of the downward liquid hole 1211 is less than the straight-line distance between the second edge portion of the downward liquid hole 1211 and the liquid inlet 1211a of the downward liquid hole 1211, so that the blocking portion 1212 is tilted toward the downward flow direction of the herbal medicine.

[0054] Of course, in other embodiments, the blocking portion 1212 may also be a plurality of protrusions arranged on the inner wall of the lower liquid hole 1211. The plurality of protrusions may be evenly distributed on the inner wall of the lower liquid hole 1211, so as to destroy the surface tension of the herbal medicine entering the lower liquid hole 1211 through the protrusions, thereby effectively preventing the problem of poor liquid discharge and dry burning.

[0055] Among them, the atomizing core 13 is arranged in the atomizing chamber, and is used to heat and atomize the herbal medicine entering the atomizing chamber when power is turned on; in a specific embodiment, the first base body 121 is specifically sleeved on the atomizing core 13, and a first pressure relief groove 1215 is opened on the surface of the first base body 121 facing the atomizing core 13, one end of the first pressure relief groove 1215 is connected to the atomizing chamber, and the other end is connected to the liquid discharge hole; the first pressure relief groove 1215 is used to prevent the generation of bubbles during the ventilation process, and circulate with the gas in the liquid storage chamber, thereby reducing the pressure difference between the liquid storage chamber and the atomizing chamber, and facilitating liquid discharge.

[0056] In one embodiment, the atomizer core 13 includes an absorbent body 131 and a heating element 132 . Among them, the liquid absorbing liquid 131 is specifically arranged on the second base body 122 to support it through the second base body 122; the first base body 121 is specifically sleeved on the liquid absorbing liquid 131; specifically, a surrounding portion 1214 is formed on the side surface of the first base body 121 facing the second base body 122, and the surrounding portion 1214 is arranged on the side surface of the blocking portion 1212 away from the liquid storage cavity, and cooperates with the blocking portion 1212 to form a receiving groove. In a specific embodiment, the first base body 121 is sleeved on the liquid absorbing liquid 131 through the receiving groove, that is, the liquid absorbing liquid 131 is snapped into the receiving groove, which not only limits and fixes the liquid absorbing liquid 131, but also allows the liquid outlet 1211b defined by the blocking portion 1212 and the mounting portion 1213 to be directly opposite to the liquid absorbing liquid 131, so that the herbal medicine flowing out of the liquid outlet 1211b can directly enter the liquid absorbing liquid 131, avoiding leakage problems.

[0057] It can be understood that during the atomization process, the atomized herbal medicine is heated in the atomization chamber, which increases the air pressure in the atomization chamber and is greater than the air pressure in the liquid storage chamber, thereby making it difficult for the herbal medicine in the liquid storage chamber to flow into the atomization chamber through the lower liquid hole 1211 under the action of the pressure difference. In order to reduce the pressure difference between the liquid storage chamber and the atomization chamber during the atomization process and facilitate the liquid discharge of the herbal medicine, the present application can further provide a first pressure relief groove 1215 at the position where the first seat body 121 contacts the liquid absorption liquid 131, and one end of the first pressure relief groove 1215 is in contact with the atomization chamber. The first pressure relief groove 1215 is connected to the cavity, and the other end is connected to the liquid lowering hole 1211, so as to prevent the generation of bubbles during the ventilation process through the first pressure relief groove 1215, and circulate with the gas in the liquid storage cavity, thereby reducing the pressure difference between the liquid storage cavity and the atomization cavity, and facilitating the liquid lowering; in one embodiment, the first pressure relief groove 1215 is specifically opened on the side surface of the blocking portion 1212 away from the liquid storage cavity, and there are multiple first pressure relief grooves 1215, and the multiple first pressure relief grooves 1215 are spaced apart along the circumferential direction of the liquid absorption liquid 131, and are symmetrically distributed on the blocking portion 1212.

[0058] The heating element 132 is disposed on a side of the absorbent body 131 away from the first base 121 and is used to heat and atomize the herbal medicine on the surface of the absorbent body 131 when powered on. Specifically, the heating element 132 can be a heating film disposed on the absorbent body 131.

[0059] The atomizer 10 provided in this embodiment is provided with a shell 11 and a mounting base 12, wherein the mounting base 12 is provided to include a first base body 121 and a second base body 122, and the first base body 121 cooperates with the shell 11 to form a liquid storage cavity to store the herbal medicine through the liquid storage cavity; at the same time, the first base body 121 and the second base body 122 cooperate to form an atomization cavity, and a lower liquid hole 1211 is formed on the first base body 121 to connect the liquid storage cavity and the atomization cavity, so that the herbal medicine in the liquid storage cavity can be discharged through the lower liquid hole 1211. The liquid flows through the liquid hole 1211 into the atomizing chamber; in addition, a blocking portion 1212 is provided on the hole wall of the lower liquid hole 1211 to destroy the surface tension of the herbal medicine flowing through the lower liquid hole 1211 through the blocking portion 1212, thereby avoiding the formation of bubbles in the process of the herbal medicine flowing through the lower liquid hole 1211, resulting in the problem of poor liquid flow; in addition, an atomizing core 13 is provided in the atomizing chamber to heat and atomize the herbal medicine entering the atomizing chamber when power is turned on to generate atomized gas for the user to inhale.

[0060] For details, see Figure 4a and Figure 7 ,in, Figure 7A schematic diagram of the structure of a first sealing member provided in one embodiment of the present application. To prevent the herbal medicine from flowing out of the gap between the first base 121 and the atomizing core 13 during the atomization process, specifically, from the gap between the first base 121 and the absorbing liquid 131, a first sealing member 14 may be further provided between the first base 121 and the absorbing liquid 131 to seal the gap therebetween. Specifically, the first sealing member 14 may include a bottom wall 141 and a side wall 142 disposed around the outer edge of the bottom wall 141. The bottom wall 141 may be provided with a through hole to expose the lower liquid hole 1211. In one specific embodiment, the first sealing member 14 may be made of silicone to enhance the sealing effect.

[0061] In a specific embodiment, to accelerate the gas flow rate between the liquid storage chamber and the atomizing chamber, thereby further improving the liquid delivery rate of the herbal medicine, a second pressure relief groove 143 may be further provided on the surface of the first sealing member 14 that contacts the atomizing core 13, i.e., the surface that contacts the liquid absorption liquid 131. One end of the second pressure relief groove 143 is connected to the atomizing chamber, and the other end is connected to the liquid delivery hole 1211.

[0062] Specifically, the second pressure relief groove 143 may include a first groove 143a and a second groove 143b that are connected to each other, the first groove 143a is connected to the lower liquid hole 1211, and the second groove 143b is connected to the atomization chamber; wherein the first groove 143a is opened on the side surface of the bottom wall 141 facing the liquid absorbing liquid 131, and the first groove 143a extends from the outer edge of the bottom wall 141 to the inner edge of the bottom wall 141 to communicate with the lower liquid hole 1211; of course, the first groove 143a can also be connected to the lower liquid hole 1211 by punching a hole on the bottom wall 141, and the present application is not limited to this; specifically, the second groove 143b is opened on the side surface of the side wall 142 facing the liquid absorbing liquid 131, and the second groove 143b extends from the end where the side wall 142 is connected to the bottom wall 141 to the end of the side wall 142 away from the bottom wall 141 to communicate with the atomization chamber.

[0063] In specific embodiments, see Figure 3 、 Figure 4a as well as Figure 8 and Figure 9 ,in, Figure 8 A schematic structural diagram of a second sealing member provided in one embodiment of the present application; Figure 9This is a schematic diagram of the structure of a second sealing member provided in another embodiment of the present application. Since the herbal medicine contains terpenes, which can corrode metal and plastic, in order to prevent the herbal medicine in the liquid storage chamber from contacting the absorbing liquid 131 for a long time when the atomizer 10 is idle, thereby corroding the absorbing liquid 131, a second sealing member 15 can be further provided on the atomizer 10. When the atomizer 10 is idle, the second sealing member 15 blocks the lower liquid hole 1211 to prevent the herbal medicine from flowing out of the lower liquid hole 1211 and contacting the absorbing liquid 131. When the atomizer 10 is in use, the lower liquid hole 1211 is exposed to allow the herbal medicine to be discharged through the lower liquid hole 1211.

[0064] Specifically, the second sealing member 15 can be slidably connected to the mounting base 12 and can be located in a first position or a second position. When the second sealing member 15 is located in the first position, it is used to block the lower liquid hole 1211 on the first base body 121 to prevent the herbal medicine from flowing out of the lower liquid hole 1211; when the second sealing member 15 is located in the second position, it is used to expose the lower liquid hole 1211 on the first base body 121, so that the herbal medicine can flow out of the lower liquid hole 1211 and enter the atomization chamber. Specifically, the product structure when the second sealing member 15 is in the first position can be seen in Figure 4a The product structure when the second sealing member 15 is in the second position can be seen in Figure 4b .

[0065] In one embodiment, at least one sliding groove is provided on the mounting seat 12; the second sealing member 15 includes a sliding portion 151 and a sealing portion 152 provided on the sliding portion 151; the sliding portion 151 extends into the sliding groove to be slidably connected with the mounting seat 12, and the sealing portion 152 is located in the first position or the second position under the drive of the sliding portion 151.

[0066] In a specific embodiment, two sliding grooves are opened on the mounting seat 12, and the sliding part 151 includes two sliding rods 151a, and the two sliding rods 151a are symmetrically arranged on the two side edges of the sealing part 152, and one end of each sliding rod 151a is connected to the sealing part 152, and the other end extends into the sliding groove to be slidably connected with the mounting seat 12; specifically, the two sliding rods 151a correspond one-to-one to the two sliding grooves, that is, one sliding rod 151a is inserted into one sliding groove.

[0067] In a specific embodiment, the sliding portion 151 is slidably connected to the mounting base 12 along a vertical direction, wherein the vertical direction specifically refers to the direction indicated by B, which is the same as the direction in which the atomizer 10 is inserted into the host 20.

[0068] Specifically, in this embodiment, see Figure 8 and Figure 9 The sliding portion 151 and the sealing portion 152 of the second sealing member 15 are arranged perpendicularly, that is, the extending direction of the sliding portion 151 is perpendicular to the plane where the sealing portion 152 is located.

[0069] Specifically, the mounting seat 12 has a first surface and a second surface arranged opposite to each other along the direction shown in the B direction. The first surface of the mounting seat 12 cooperates with the shell 11 to form a liquid storage chamber, and the slide groove extends along the axial direction of the mounting seat 12 (the B direction) and extends from the first surface of the mounting seat 12 to the second surface; in a specific embodiment, the axial dimension of the slide rod 151a is greater than the axial dimension of the slide groove, and the end of the slide rod 151a away from the sealing portion 152 extends from the first surface of the mounting seat 12 into the slide groove and extends from the second surface of the mounting seat 12; when the atomizer 10 is idle, the second sealing member 15 is in the first position. At this time, the sealing portion 152 is located on the side surface of the first seat body 121 away from the second seat body 122, that is, the sealing portion 151 ... 52 is located on the first surface of the mounting seat 12 and covers the lower liquid hole 1211, and part of the two slide rods 151a of the sliding portion 151 extends out of the second surface of the mounting seat 12; and when the atomizer 10 needs to be used, that is, when the atomizer 10 is inserted into one end port of the host 20, the two slide rods 151a on the atomizer 10 extend out of the part of the mounting seat 12 and abut against one end port of the host 20, and move in the direction away from the atomizer 10 and inserted into the host 20 under the reaction force of the host 20, so that the sealing portion 152 is spaced apart from the first seat body 121 and the lower liquid hole 1211 is exposed, so that the herbal medicine in the liquid storage chamber can flow out through the lower liquid hole 1211; at this time, the second sealing member 15 is located in the second position.

[0070] It should be noted that the housing 11 is further formed with an air outlet channel 111 along its axial direction (direction B), and the air outlet channel 111 has an air inlet end and an air outlet end. The air inlet end of the air outlet channel 111 is specifically mounted on the mounting portion 1213 of the first seat body 121, and the air inlet end of the air outlet channel 111 is communicated with the atomization chamber, and the air outlet end is communicated with the outside air. In a specific embodiment, the sealing portion 152 may be an integrally formed plate-like structure. In order to prevent the air outlet channel 111 from obstructing the sliding of the second sealing member 15, an avoidance hole 152a may be formed on the sealing portion 152 to avoid the position of the air outlet channel 111 through the avoidance hole 152a. For the specific structure, please refer to Figure 8 In another embodiment, see Figure 9 The sealing portion 152 may include two sealing portions 1521 and a sleeve portion 1522 arranged between the two sealing portions 1521; in this embodiment, the two sliding rods 151a are respectively connected to the two sealing portions 1521, and the projection of one of the two sealing portions 1521 can cover at least one of the lower liquid holes 1211, and the projection of the other sealing portion 1521 can cover at least the other lower liquid hole 1211; an avoidance hole 152a is provided on the sleeve portion 1522, and the sleeve portion 1522 is sleeved on the outer wall of the air outlet channel 111 through the avoidance hole 152a.

[0071] In another embodiment, the sliding portion 151 can be slidably connected to the mounting base 12 along a transverse direction, wherein the transverse direction specifically refers to a direction indicated by a C direction. The C direction is perpendicular to the direction in which the atomizer 10 is inserted into the main unit 20 .

[0072] In this embodiment, see Figure 10 , Figure 10 A schematic structural diagram of a second sealing member provided for another embodiment of the present application; the sliding portion 151 of the second sealing member 15 is arranged in parallel with the sealing portion 152, that is, the extension direction of the sliding portion 151 is parallel to the plane where the sealing portion 152 is located; and in this embodiment, in order to prevent the air outlet channel 111 from obstructing the sliding process of the sealing portion 152, the sealing portion 152 can form an inwardly recessed bending portion 152b at a position corresponding to the air outlet channel 111, that is, the bending portion 152b extends in a direction away from the air outlet channel 111 to avoid the position where the air outlet channel 111 is located.

[0073] Specifically, in this embodiment, the two chutes are respectively provided on both sides of the two lower liquid holes 1211, and extend from one side edge toward the other side edge of the mounting seat 12. The extension direction is specifically the same as the radial direction (C direction) of the mounting seat 12, so that the sliding portion 151 can drive the sealing portion 152 to move toward or away from the lower liquid hole 1211 at the same time during the sliding process. It can be understood that if the two chutes extend along the D direction, during the specific sliding process, the air outlet channel 111 will block the sliding process of the sealing portion 152, so that the sealing portion 152 cannot cover the two lower liquid holes 1211 at the same time. Specifically, in this embodiment, The axial dimension of the slide groove is greater than the axial dimension of the slide rod 151a. When the atomizer 10 is not in use, the second sealing member 15 is in the first position. At this time, the sealing portion 152 is located on the side surface of the first base body 121 away from the second base body 122, and blocks the lower liquid hole 1211 on the first base body 121. The end of the slide rod 151a away from the sealing portion 152 extends from the side edge of the mounting seat 12. When the atomizer 10 is needed, the second sealing member 15 is in the second position. At this time, the sealing portion 152 is located at another position of the first base body 121 away from the lower liquid hole 1211 to expose the lower liquid hole 1211, and the slide rod 151a extends into the mounting seat 12. Of course, in other embodiments, the second sealing member 15 can also block or expose the lower liquid hole 1211 by rotating, and this embodiment is not limited to this.

[0074] In a specific embodiment, in order to improve the sealing effect of the second sealing member 15, when the second sealing member 15 is located in the first position, at least part of the sealing portion 152 can be located in the lower liquid hole 1211 and have an interference fit with the lower liquid hole 1211. For details, see Figure 4a .

[0075] For details, see Figure 3 and Figure 11 ,in, Figure 11 A cross-sectional view of a product provided on an atomizer according to an embodiment of the present application, in which a third seal and a fourth seal are provided; the atomizer 10 further includes a third seal 16 and a fourth seal 17, wherein the third seal 16 can be specifically arranged at one end of the air outlet channel 111 away from the atomizing chamber, that is, at the air outlet end of the air outlet channel 111, to seal the air outlet channel 111; an air inlet is formed on the second base 122, and the air inlet is connected to the atomizing chamber, and the fourth seal 17 can be specifically arranged at one end of the air inlet away from the atomizing chamber to seal the air inlet, thereby preventing leakage when the atomizer 10 is idle; it should be noted that when the atomizer 10 needs to be used, the third seal 16 and the fourth seal 17 are removed. The specific product structure of the atomizer 10 after removing the third seal 16 and the fourth seal 17 can be seen in FIG. Figure 4a or Figure 4b .

[0076] Specifically, the third sealing member 16 and the fourth sealing member 17 may be made of silicone.
