[0043] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence unless it is stated that a certain sequence must be followed.

[0044] The serial numbers assigned to components in this text, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0045] In the related art, when condensate droplets fall onto the circuit board, it is likely to cause the problem of circuit board contamination.

[0046] In this application, the circuit board and the air flow channel are isolated to solve the above technical problem.

[0047] Please refer to Figures 3 to 10 , in one embodiment, the embodiment of this application provides a main body of an electronic atomization device, which is suitable for powering an atomizer. The main body includes:

[0048] A housing 11;

[0049] A power supply component 12, arranged inside the housing 11, including a circuit board 121 and a battery cell 122; wherein,

[0050] The housing 11 includes,

[0051] An air flow channel 1124, an air inlet hole 11241 of the air flow channel 1124 is arranged on the housing, the air flow channel 1124 and the circuit board 121 are isolated from each other, and an air outlet hole 11242 of the air flow channel 1124 is used to establish an air flow connection with the atomizer;

[0052] An air regulating valve assembly 14, at least part of which is movably arranged relative to the air inlet hole 1241, and the air regulating valve assembly 14 is configured to adjust the effective air intake area of the air inlet hole 1241 by moving.

[0053] It can be seen from the above embodiment that in the embodiment of the application, since the air inlet hole 11241 of the air flow channel 1124 is arranged on the housing, the air flow channel 1124 and the circuit board 121 are isolated from each other, and the air outlet hole 11242 of the air flow channel 1124 is used to establish an air flow connection with the atomizer, the condensate generated in the air flow channel 1124 will flow back into the air flow channel 1124 along the opposite direction of the air flow in the air flow channel 1124. At the same time, the condensate is isolated from the circuit board 121 through the middle frame support 112, avoiding the related function failure of the circuit board 121 due to the condensate. In this way, the main body provided by the embodiment of this application will not only not affect the normal use of the main body due to the inflow of condensate, but also can extend the service life of the main body.

[0054] Among them, the housing 11 in the above embodiments can be a single-layer housing 11 structure, a double-layer housing 11 structure, or other forms of housing 11 structures, which are not limited in the embodiments of the present invention. The housing 11 can be a cylindrical structure so that the housing 11 can enclose an installation cavity.

[0055] In addition, it should be noted that the mutual isolation of the air flow channel 1124 and the circuit board 121 can be understood as that the channel where the air flow channel 1124 is located and the installation cavity where the circuit board 121 is located are not in communication with each other. That is, the channel where the air flow channel 1124 is located and the installation cavity where the circuit board 121 is located are two independent cavities formed by the housing 11, and the gas and condensate flowing in the air flow channel 1124 will not enter the installation cavity where the circuit board 121 is located.

[0056] In addition, the air regulating valve assembly 13 is a component for regulating the flow rate of the air inlet hole 1421. That is, it is a control valve for realizing the entry of the gas outside the housing 11 into the air flow channel 1124. The air regulating valve assembly 13 can be movably connected to the housing 11 by means of sliding connection, hinged connection, snap connection, etc. In addition, the installation position of the air regulating valve assembly 13 on the housing 11 should correspond to the position where the air flow channel 1124 is provided on the peripheral side wall 1122 so that the air inlet hole 11241 can communicate the gas outside the housing 11 and the air flow channel 1124.

[0057] It should be noted that in the embodiments of the present application, the flow direction of the air flow is from the air inlet hole 1421 into the air flow channel 1124 and then from the air flow channel 1124 into the air outlet hole 125, while the flow direction of the condensate is opposite to the flow direction of the gas in the air flow channel 1124.

[0058] In some embodiments, as Figure 4 and Figure 5 shown, the housing 11 includes an outer shell 111 and a middle frame support 112 provided inside the outer shell 111; the middle frame support 112 includes a top wall 1121 and a peripheral side wall 1122, and the top wall 1121 and the peripheral side wall 1122 enclose a receiving cavity 1123, and the power supply assembly 12 is arranged in the receiving cavity 1123; the air flow channel 1124 is arranged on the peripheral side wall 1122, and the air outlet hole 11242 of the air flow channel 1124 is arranged on the top wall 1121.

[0059] In this embodiment, the middle frame bracket 112 installed inside the housing 111 is mainly used to install electronic devices inside the host, such as a circuit board 121 or a display module, etc. The middle frame bracket 112 has a frame-shaped structure. The plane where the top wall 1121 included in the middle frame bracket 112 is located intersects with the plane where the peripheral side wall 1122 is located. A square frame-shaped structure can be formed between the peripheral side wall 1122 and the top wall 1121, enclosing a receiving cavity 1123, and then used to install the circuit board 121.

[0060] Furthermore, as Figure 8 and Figure 9 shown, an air flow channel 1124 is formed on the peripheral side wall 1122. The air flow channel 1124 is a through-hole structure formed on the peripheral side wall 1122. One end of the air flow channel 1124 is configured as an air outlet 11242, and the other end of the air flow channel 1124 is configured to be communicated with an air inlet 11241.

[0061] It should be noted that the through-hole structure extends to the position where the air outlet 125 formed on the top wall 1121 is located, so as to enable communication between the air flow channel 1124 and the air outlet 125. In some embodiments, a conductive electrode of the host is also provided at the top wall 1121. Therefore, an avoidance structure, such as a through groove or a notch structure, needs to be formed on the periphery of the conductive electrode to ensure the communication between the air flow channel 1124 and the air outlet 125. In addition, the air flow channel 1124 is formed in the peripheral side wall 1122, that is, the peripheral side wall 1122 can cover the air flow channel 1124, so that a part of the structure of the peripheral side wall 1122 is also provided between the air flow channel 1124 and the receiving cavity 1123 for shielding, so as to isolate the air flow channel 1124 and the receiving cavity 1123 from each other, that is, to achieve the effect of isolating the air flow channel 1124 and the circuit board 121 from each other. In addition, it should be further noted that in addition to condensate that can be accommodated in the air flow channel 1124, oil leakage generated by the host can also be accommodated in the air flow channel 1124, and the embodiments of the present application do not limit this.

[0062] In one embodiment, as Figure 10 shown, for the structure of the adjustment assembly, the air regulating valve assembly 13 may include an adjustment block 131 and an air flow control plate 132; the air flow control plate 132 has at least one air flow adjustment hole 1321, and the adjustment block 131 is configured to drive the air flow control plate 132 to move relative to the air inlet 11241 to adjust the overlapping area between the air flow adjustment hole 1321 and the air inlet 11241.

[0063] It should be noted that in this embodiment, the adjusting block 131 can be in a rod-shaped or block-shaped structure, and thus a stable force application point can be provided for the operator through the adjusting block 131. The air flow control plate 132 is in a plate-shaped structure, and this plate-shaped structure can be a strip-shaped plate structure, a circular plate-shaped structure or a plate-shaped structure of other shapes. The overlapping area between the air flow control plate 132 and the air inlet hole 11241 can be adjusted by means of relative movement such as sliding and rolling between the air flow adjusting hole 1321 and the air inlet hole 11241. That is to say, the conduction area between the air flow adjusting hole 1321 and the air inlet hole 11241 can be adjusted to change the size of the gas flow entering the air inlet hole from the air flow adjusting hole 1321, so as to meet different gas flow requirements and improve the use experience of the host.

[0064] In some embodiments, the position where the installation through groove 1111 is opened on the housing 11 should be in a relative position with the position where the sliding groove 1125 is opened on the middle frame bracket 112. The positive projection of the adjusting block 131 in the first direction is located within the positive projection of the installation through groove 1111 in the first direction, and the area of the positive projection of the installation through groove 1111 in the first direction should be larger than the area of the positive projection of the adjusting block 131 in the first direction. In other words, there should be enough space between the adjusting block 131 and the groove wall of the installation through groove 1111 to facilitate sufficient movement space of the adjusting block 131 in the installation through groove 1111. The positive projection of the air flow control plate 132 in the first direction is located within the positive projection of the sliding groove 1125 in the first direction, and the area of the positive projection of the sliding groove 1125 in the first direction should be larger than the area of the positive projection of the air flow control plate 132 in the first direction. In other words, there should be enough space between the air flow control plate 132 and the groove wall of the sliding groove 1125 to facilitate the sliding of the air flow control plate 132 in the sliding groove 1125. In addition, the area of the positive projection of the air flow control plate 132 in the first direction should be larger than the area of the positive projection of the installation through groove 1111 in the first direction, so that the air flow control plate 132 can be located between the housing 11 and the bottom of the sliding groove 1125, facilitating the sliding of the air flow control plate 132 in the sliding groove 1125.

[0065] In one embodiment, the air regulating valve assembly 13 further includes a friction sliding plate 133; the friction sliding plate 133 is arranged between the air flow control plate 132 and the air inlet hole 11241, and a gas through hole 1331 communicating with the air flow adjusting hole 1321 is opened on the friction sliding plate 133, and the adjusting block 131 is connected to both the air flow control plate 132 and the friction sliding plate 133 at the same time; wherein, the material damping of the friction sliding plate 133 is greater than the material damping of the air flow control plate 132.

[0066] In this embodiment, the friction sliding plate 133 can be connected between the air flow control plate 132 and the air inlet hole 11241 by means of snap connection, bonding, screw connection, etc. The number of gas through holes 1331 formed on the friction sliding plate 133 is equal to the number of air flow adjustment holes 1321 formed on the air flow control plate 132, and any one of the gas through holes 1331 has a corresponding air flow adjustment hole 1321. In other words, any one of the gas through holes 1331 has an air flow adjustment hole 1321 that is in the same straight line in the first direction. The adjustment block 131 is connected to both the air flow control plate 132 and the friction sliding plate 133, so that the adjustment block 131 can drive the air flow control plate 132 and the friction sliding plate 133 to slide simultaneously. Since the material damping of the friction sliding plate 133 is greater than that of the air flow control plate 132, and the friction sliding plate 133 is arranged between the air flow control plate 132 and the sliding groove 1125, the friction force during the sliding of the air flow regulating valve assembly 13 can be increased through the friction sliding plate 133, thereby enhancing the damping feeling during the sliding of the air flow regulating valve assembly 13 and improving the operation experience of the host. It should be noted that the friction sliding plate 133 can be made of materials such as butyl, acrylate, polysulfide, nitrile and silicone rubber, polyurethane, polyvinyl chloride and epoxy resin, and the embodiments of the present application do not limit this.

[0067] In some embodiments, an installation through groove 1111 is formed on the outer shell 111, a sliding groove 1125 is formed on the middle frame bracket 112, the air flow control plate 132 is arranged between the middle frame bracket 112 and the outer shell 111, and is movably arranged in the sliding groove 1125.

[0068] It should be noted that the position of the installation slot 1111 provided on the housing 111 should be in a relative position to the position of the sliding slot 1125 provided on the middle frame bracket 112. The orthographic projection of the adjustment block 131 in the second direction is located within the orthographic projection of the installation slot 1111 in the second direction, and the area of ​​the orthographic projection of the installation slot 1111 in the second direction should be larger than the area of ​​the orthographic projection of the adjustment block 131 in the second direction. In other words, there should be enough space between the adjustment block 131 and the groove wall of the installation slot 1111 so that the adjustment block 131 has sufficient movement space in the installation slot 1111. The orthographic projection of the airflow control plate 132 in the second direction is located within the orthographic projection of the sliding slot 1125 in the second direction, and the area of ​​the orthographic projection of the sliding slot 1125 in the second direction should be larger than the area of ​​the orthographic projection of the airflow control plate 132 in the second direction. In other words, there should be enough space between the airflow control plate 132 and the groove wall of the sliding slot 1125 so that the airflow control plate 132 can slide in the sliding slot 1125. In addition, the area of ​​the direct projection of the airflow control plate 132 in the second direction should be larger than the area of ​​the direct projection of the mounting slot 1111 in the second direction, so that the airflow control plate 132 can be located between the outer shell 111 and the bottom of the sliding slot 1125, facilitating the sliding of the airflow control plate 132 in the sliding slot 1125.

[0069] The multiple airflow adjustment holes 1321 provided on the airflow control plate 132 are used to control the flow rate of the gas outside the housing 111 entering the airflow channel 1124. Specifically, when the adjustment block 131 controls the airflow control plate 132 in the first state (the adjustment block 131 drives the airflow control plate 132 to slide to a predetermined position in the sliding groove 1125), the orthographic projections of the multiple airflow adjustment holes 1321 in the second direction are located outside the orthographic projections of the installation slot 1111 in the second direction, that is, the airflow control plate 132 can cover the installation slot 1111, thereby making the installation slot 1111 non-conductive. In this state, the gas outside the housing 111 cannot enter the airflow channel 1124. When the adjustment block 131 controls the airflow control plate 132 to be in the second state (the adjustment block 131 drives the airflow control plate 132 to slide to a predetermined position in the sliding groove 1125), the orthographic projection of at least one airflow adjustment hole 1321 in the second direction is located within the orthographic projection of the mounting groove 1111 in the second direction, that is, at least one airflow adjustment hole 1321 and a partial area of ​​the mounting groove 1111 are in the same straight line in the second direction, so that the airflow outside the housing 111 can pass through the mounting groove 1111 via the airflow adjustment hole 1321 and flow into the airflow channel 1124.

[0070] In this embodiment, when the number of air flow adjustment holes 1321 whose partial areas aligned with the installation through slot 1111 in the second direction is different, the gas flow rate entering the air flow channel 1124 from outside the housing 111 is also different. In other words, the more the number of air flow adjustment holes 1321 whose partial areas aligned with the installation through slot 1111 in the second direction, the greater the gas flow rate entering the air flow channel 1124 from outside the housing 111; the fewer the number of air flow adjustment holes 1321 whose partial areas aligned with the installation through slot 1111 in the second direction, the smaller the gas flow rate entering the air flow channel 1124 from outside the housing 111. Exemplarily, taking the air flow control plate 132 including three air flow adjustment holes 1321 as an example, when the adjustment block 131 drives the air flow control plate 132 to slide in the sliding slot 1125 until the orthographic projection of one air flow adjustment hole 1321 in the second direction is located within the orthographic projection of the installation through slot 1111 in the second direction, the gas flow rate entering the air flow channel 1124 from outside the housing 111 is only the flow rate corresponding to the aperture size of one air flow adjustment hole 1321. When the adjustment block 131 drives the air flow control plate 132 to slide in the sliding slot 1125 until the orthographic projections of two air flow adjustment holes 1321 in the second direction are located within the orthographic projection of the installation through slot 1111 in the second direction, the gas flow rate entering the air flow channel 1124 from outside the housing 111 is only the flow rate corresponding to the aperture sizes of two air flow adjustment holes 1321. When the adjustment block 131 drives the air flow control plate 132 to slide in the sliding slot 1125 until the orthographic projections of three air flow adjustment holes 1321 in the second direction are located within the orthographic projection of the installation through slot 1111 in the second direction, the gas flow rate entering the air flow channel 1124 from outside the housing 111 is only the flow rate corresponding to the aperture sizes of three air flow adjustment holes 1321.

[0071] In summary, in this embodiment, the adjustment block 131 can drive the air flow control plate 132 to slide to different positions in the sliding slot 1125, thereby changing the gas flow rate entering the air flow channel 1124 from outside the housing 111 to meet different gas flow rate requirements and improve the usage experience of the host.

[0072] In addition, it should be noted that in the embodiment of the present application, the orthographic projection in the second direction can be understood as the projection on a plane perpendicular to the second direction, and the plane perpendicular to the second direction is a virtual plane. The above-mentioned second direction is the direction intersecting with the air flow direction in the air flow channel 1124.

[0073] In one embodiment, the air flow control plate 132 includes a plurality of air flow adjustment holes 1321. The hole pitch between every two adjacent air flow adjustment holes 1321 is equal. Among the plurality of air flow adjustment holes 1321, the hole pitch between every two adjacent air flow adjustment holes 1321 is equal. In this way, when increasing or decreasing the intake air flow corresponding to each air flow adjustment hole 1321, the distance that the adjustment block 131 controls the air flow control plate 132 to slide in the sliding groove 1125 is equal. Furthermore, it is convenient to control the magnitude of the air flow entering the air flow channel 1124 from outside the housing 111.

[0074] In one embodiment, an intake air groove 1126 is formed at the bottom of the sliding groove 1125. An air flow channel 1124 is formed in the groove wall of the intake air groove 1126 in the first direction, where the first direction is the flowing direction of the air flow in the air flow channel 1124.

[0075] It should be noted that in this embodiment, during intake, at least one air flow adjustment hole 1321, a partial position of the installation through groove 1111, and the intake air groove 1126 are in a straight line in the first direction. In this way, by forming the air flow channel 1124 in the groove wall of the intake air groove 1126 in the first direction, the airtightness of the air flow channel 1124 can be ensured, and it can be ensured that the gas can reach the air outlet hole 125 through the air flow channel 1124.

[0076] In one embodiment, a receiving groove is further formed in the groove wall of the intake air groove 1126 in the first direction. The groove wall where the receiving groove is located and the groove wall where the air flow channel 1124 is located are two opposite groove walls of the intake air groove 1126 in the first direction. In this way, since the groove wall where the receiving groove is located and the groove wall where the air flow channel 1124 is located are two opposite groove walls of the intake air groove 1126 in the first direction, when the condensate formed after gas condensation flows back to the intake air groove 1126 through the air flow channel 1124, it can further flow into the receiving groove, thereby improving the condensate collection capacity. At the same time, it is avoided that the condensate accumulates in the intake air groove 1126 and affects the intake.

[0077] In one embodiment, the adjustment block 131 includes a connected mounting portion 1311 and a connecting portion 1312; the air flow control plate 132 is provided with a first mounting hole 1322, and the friction sliding plate 133 is provided with a second mounting hole 1332. The first mounting hole 1322 and the second mounting hole 1332 are coaxially arranged in the second direction. The mounting portion 1311 sequentially passes through the first mounting hole 1322 and the second mounting hole 1332; a ring-shaped convex structure 1323 is provided on the surface of the air flow control plate 132 away from the friction sliding plate 133. The ring-shaped convex structure 1323 surrounds the first mounting hole 1322, and the ring-shaped convex structure 1323 encloses an embedded cavity. The connecting portion 1312 is embedded in the embedded cavity; the end of the connecting portion 1312 away from the mounting portion 1311 extends out of the notch of the mounting through groove 1111 away from the accommodating cavity 1123.

[0078] It should be noted that in this embodiment, the size of the mounting portion 1311 can be larger than the size of the connecting portion 1312. In this way, when the mounting portion 1311 sequentially passes through the first mounting hole 1322 and the second mounting hole 1332, and the connecting portion 1312 is embedded in the embedded cavity, while ensuring the tight connection of the air flow control plate 132, the friction sliding plate 133 and the adjustment block 131, the connecting portion 1312 can cover the mouth of the first mounting hole 1322 to ensure that the gas outside the housing 111 does not flow in through the gap between the first mounting hole 1322 and the mounting portion 1311, improving the accuracy of the air flow control plate 132 in controlling the gas flow. In addition, since the end of the connecting portion 1312 away from the mounting portion 1311 extends out of the notch of the mounting through groove 1111 away from the accommodating cavity 1123, it can ensure that the end of the connecting portion 1312 away from the mounting portion 1311 can provide a stable force application point for the operator, making it more convenient for the operator to slide.

[0079] In one embodiment, a clamping groove 1324 is provided on the surface of the air flow control plate 132 close to the sliding groove 1125, and a clamping protrusion 1333 is provided on the surface of the friction sliding plate 133 away from the sliding groove 1125; the clamping protrusion 1333 is clamped in the clamping groove 1324. In this way, the disassembly and assembly between the air flow control plate 132 and the friction sliding plate 133 are facilitated by the clamping method, and it can ensure the synchronous sliding of the air flow control plate 132 and the friction sliding plate 133. At the same time, when the friction sliding plate 133 is damaged due to long-term sliding, it is convenient to disassemble the air flow control plate 132 and the friction sliding plate 133, facilitating the replacement of the friction sliding plate 133.

[0080] In one embodiment, a plurality of sliding protrusions 1334 are provided on the contact surface between the friction sliding plate 133 and the sliding groove 1125. In this way, the plurality of sliding protrusions 1334 protrude from the surface of the friction sliding plate 133 facing the sliding groove 1125. Therefore, the sliding area of the entire friction sliding plate 133 can be reduced by the plurality of sliding protrusions 1334, the force required for the entire sliding can be reduced, and the smoothness of the sliding can be improved.

[0081] As can be seen from the above embodiments, in the application embodiments, since the air inlet holes 11241 of the air flow channel 1124 are provided on the housing, the air flow channel 1124 and the circuit board 121 are isolated from each other, and the air outlet holes 11242 of the air flow channel 1124 are used to establish an air flow connection with the atomizer. Therefore, the condensate generated in the air flow channel 1124 will flow back into the air flow channel 1124 along the opposite direction of the air flow in the air flow channel 1124. At the same time, the condensate is isolated from the circuit board 121 through the middle frame bracket 1124 to avoid contaminating the circuit board 121. In this way, the main unit provided by the application embodiments of the present application will not only not affect the normal use of the main unit due to the inflow of condensate, but also can extend the service life of the main unit.

[0082] In addition, referring to Figure 1 and Figure 2 , in some embodiments, the application embodiments of the present application further provide an atomization device 1, and the atomization device 1 includes an atomizer 2 and the main unit 1 of any of the above embodiments; the main unit 1 and the atomizer 2 are detachably electrically connected.
