It should be understood that these directional terms are intended solely to facilitate the description of this application and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used solely to distinguish between different objects and do not imply similarity or connection between them.

[0033] One aspect of an embodiment of the present application provides a flow regulating assembly 100 , as shown in FIG. 1 to FIG. 4 , including a housing 1 and a regulating member 2 .

[0034] A main flow channel 1a is formed in the housing 1; a first flow port 1b is formed on an axial sidewall of the housing 1, and a second flow port 1c is formed on the circumferential sidewall of the housing 1. The first flow port 1b and the second flow port 1c are both connected to the main flow channel 1a. Specifically, taking the perspective of Figure 4 as an example, the housing 1 is generally a hollow tubular structure, with the axial direction being the same as the up-down direction. The first flow port 1b and the second flow port 1c can both be used for connecting pipes. Liquid medium can flow into the main flow channel 1a from the first flow port 1b and flow out from the second flow port 1c. Alternatively, the liquid medium can also flow into the main flow channel 1a from the second flow port 1c and flow out from the first flow port 1b.

[0035] At least a portion of the regulating member 2 is disposed within the main channel 1a. The regulating member 2 rotates about the axial direction of the housing 1 to adjust the flow rate of the first flow opening 1b entering the main channel 1a. In other words, the regulating member 2 can be partially disposed within the main channel 1a or completely disposed within the main channel 1a. For example, the lower end of the regulating member 2 is disposed within the main channel 1a and can rotate about the axial direction of the housing 1. During this rotation, the regulating member 2 can completely close the first flow opening 1b or change the liquid outlet area of ​​the first flow opening 1b, thereby adjusting the flow rate of the first flow opening 1b entering the main channel 1a.

[0036] The flow regulating assembly 100 can be used in an electronic atomization device 1000. Taking the flow regulating assembly 100 of an embodiment of the present application as an example, refer to FIG8 . On the other hand, the present application provides an electronic atomization device 1000, including an air pump 200, an atomization chamber 210, a liquid storage chamber 220, an air supply channel 230, a liquid supply channel 240, and any one of the flow regulating assemblies 100 described in the embodiments of the present application.

[0037] The air pump 200 supplies air to the atomizing chamber 210 through the air supply channel 230, and the liquid storage chamber 220 supplies liquid to the atomizing chamber 210 through the liquid supply channel 240. The airflow and the atomized liquid meet and mix in the atomizing chamber 210 to form atomized liquid droplets. The flow regulating component 100 is arranged on the liquid supply channel, the first flow port 1b is connected to the liquid storage chamber 220, and the second flow port 1c is connected to the atomizing chamber 210 to regulate the flow of the liquid supply channel. Specifically, the electronic atomizing device 1000 also includes an atomizing component having an atomizing chamber 210 and a liquid storage tank component having a liquid storage chamber 220. The liquid storage chamber 220 is used to accommodate and store atomized liquid. The atomized liquid includes but is not limited to liquid media such as liquid medicine, beauty liquid, and smoke liquid. In other words, the electronic atomizing device 1000 can be used in the field of beauty atomization, the field of liquid medicine atomization, and the field of smoke liquid atomization. The atomized liquid is atomized in the atomizing chamber 210, and the liquid supply channel 240 is used to introduce the atomized liquid in the liquid storage chamber 220 into the atomizing chamber 210. The two ends of the air supply channel 240 are respectively connected to the atomizing chamber 210 and the pumping port of the air pump 200 to deliver the air flow pumped by the air pump 200 into the atomizing chamber 210. The first flow port 1b is connected to the liquid storage chamber 220, and the second flow port 1c is connected to the atomizing chamber 210. During use, the user can adjust the flow rate of the atomized liquid flowing from the liquid supply channel 240 into the atomizing chamber 210 by controlling the flow regulating component 100 to change the mist output of the atomizing component, thereby improving the user experience.

[0038] In one embodiment, please refer to Figure 9, the electronic atomization device 1000 also includes a heater 250. After the airflow and the atomized liquid meet and mix in the atomizing chamber 210, atomized liquid droplets are formed and sprayed out from the atomizing chamber 210. The heater 250 can further heat the atomized liquid droplets sprayed from the atomizing chamber 210 to atomize them to form an aerosol with smaller particle size. In particular, when the atomized liquid is a medicinal liquid or a smoke liquid, the secondary atomization by the heater 250 can further improve the user experience.

[0039] The embodiment of the present application provides a flow regulating assembly 100, which, on the one hand, has a regulating member 2 and a housing 1. The regulating member 2 only needs to rotate axially around the housing 1 to directly regulate the flow of the first flow port 1b into the main channel 1a. Compared with complex structures that require more energy and time to adjust, the overall structure of the flow regulating assembly 100 of the present application is simple and compact, the flow regulation changes are more linear and smooth, the corresponding time of flow regulation is shorter, and the working reliability of the flow regulating assembly 100 is high. On the other hand, the flow regulating assembly 100 can be set on the liquid supply flow channel of the electronic atomization device 1000. During use, the user can adjust the flow of the atomized liquid flowing from the liquid supply channel into the atomization chamber by controlling the flow regulating assembly 100, so that the liquid supply flow rate and the heating power of the atomization assembly are within a reasonable range, thereby realizing the active control of the electronic atomization device 1000 over the flow regulation, and the quality of the aerosol generated after atomization is more stable, thereby improving the user experience.

[0040] In one embodiment, as shown in Figures 4 to 7 , the regulating member 2 has a fully closed position and a fully open position. When the regulating member 2 is in the fully closed position, the regulating member 2 seals the first flow port 1b. When the regulating member 2 is in the fully open position, the liquid outlet area of ​​the first flow port 1b reaches its maximum. The regulating member 2 continuously rotates between the fully closed and fully open positions to adjust the liquid outlet area of ​​the first flow port 1b. In other words, when the regulating member 2 continuously rotates axially relative to the housing 1 between the fully closed and fully open positions, the liquid outlet area of ​​the first flow port 1b continuously changes with the rotation of the regulating member 2. Therefore, the flow regulating assembly 100 of the present application can achieve stepless flow regulation.

[0041] In one embodiment, referring to Figures 5 to 7, a flow groove 2a is formed on a portion of the circumferential surface of one end of the adjusting member 2 facing the first flow outlet 1b, and the end surface of the adjusting member 2 facing the first flow outlet 1b is an adjusting surface 2b; when the adjusting member 2 is in a fully open position, the adjusting surface 2b is misaligned with at least a portion of the first flow outlet 1b, and when the adjusting member 2 is in a fully closed position, the adjusting surface 2b closes the first flow outlet 1b.

[0042] Specifically, the regulating member 2 is a rod-shaped structure, with a flow groove 2a for connecting to the first flow port 1b, and an adjusting surface 2b for adjusting the liquid outlet area of ​​the first flow port 1b. The housing 1 forms a flow plate 121 at one axial end of the first flow port 1b. The regulating surface 2b of the regulating member 2 abuts against the flow plate 121. During the circumferential rotation of the regulating member 2, the regulating surface 2b can completely close the first flow port 1b, partially close the first flow port 1b, or completely displace from the first flow port 1b, thereby continuously changing the liquid outlet area of ​​the first flow port 1b. When the regulating member 2 is in the fully open position, the liquid outlet area of ​​the first flow port 1b flowing into the flow groove 2a reaches its maximum on a projection plane perpendicular to the axial direction of the housing 1. When the regulating member 2 is in the fully closed position, the regulating surface 2b completely closes the first flow port 1b.

[0043] The shape of the first flow outlet 1b is not particularly limited, and the first flow outlet 1b can be circular, elliptical, square, polygonal, etc. In one embodiment, please refer to Figure 5. On the projection plane perpendicular to the axial direction of the housing 1, the projection of the first flow outlet 1b is an arc extending in the circumferential direction. The first flow outlet 1b has an arc-shaped structure, which can ensure that the change in the liquid outlet area of ​​the first flow outlet 1b remains stable each time the adjusting member 2 rotates a preset angle. The user can accurately determine the current liquid outlet area of ​​the first flow outlet 1b according to the rotation angle of the adjusting member 2. Exemplarily, in one embodiment, the curvature range of the arc is 120° to 180°. Specifically, the curvature range of the arc can take values ​​such as 120°, 130°, 140°, 150°, 160°, 170°, and 180°.

[0044] In one embodiment, please refer to Figures 5 to 7. On the projection plane perpendicular to the axis of the adjusting rod, the projection of the through-flow groove 2a is fan-shaped. Each time the preset angle is rotated, the radius edge of the fan cooperates with the arc structure of the first flow outlet 1b to uniformly change the liquid outlet area of ​​the first flow outlet 1b, so that the change in the liquid outlet area of ​​the first flow outlet 1b each time remains stable, further ensuring that the current liquid outlet area of ​​the first flow outlet 1b can be accurately determined by the rotation angle of the adjusting member 2, thereby achieving precise adjustment of the liquid supply flow rate. Exemplarily, in one embodiment, the angle range of the fan is 100° to 150°. Specifically, the angle range of the fan can take values ​​such as 100°, 110°, 120°, 130°, 140°, and 150°.

[0045] In one embodiment, the radius of the inner arc edge 1ba of the first flow outlet 1b is 0.5 mm to 0.7 mm. Specifically, the radius of the inner arc edge 1ba can be 0.5 mm, 0.6 mm, or 0.7 mm. In one embodiment, the radius of the outer arc edge 1bb of the first flow outlet 1b is 0.9 mm to 1.1 mm. Specifically, the radius of the outer arc edge 1bb can be 0.9 mm, 1.0 mm, or 1.1 mm.

[0046] Because fluid can pass through the gap between the inner arc edge 1ba and the outer arc edge 1bb of the first flow outlet 1b, the larger the gap between the inner arc edge 1ba and the outer arc edge 1bb, the greater the change in the liquid outlet area of ​​the first flow outlet 1b each time the adjusting member 2 rotates by a preset angle. The smaller the gap between the inner arc edge 1ba and the outer arc edge 1bb, the smaller the change in the liquid outlet area of ​​the first flow outlet 1b each time the adjusting member 2 rotates by a preset angle. Therefore, by appropriately setting the dimensions of the inner arc edge 1ba and the outer arc edge 1bb, the change in the liquid outlet area of ​​the first flow outlet 1b each time the adjusting member 2 rotates by a preset angle can be effectively adjusted.

[0047] The flow regulating assembly 100 provided in the embodiment of the present application can achieve precise regulation within a flow range of no more than 0.1 ml / s by reasonably setting the shape and size parameters of the first flow port 1b, the regulating surface 2b and the flow groove 2a.

[0048] In one embodiment, referring to Figures 3 and 4 , the flow regulating assembly 100 includes an elastic member 3, the ends of which are respectively connected to the housing 1 and the regulating member 2, so that the regulating member 2 maintains contact with the axial sidewall of the housing 1 where the first flow opening 1b is formed. In other words, the elastic force generated by the elastic member 3 constantly keeps the regulating surface 2b in contact with the flow plate 121, preventing the regulating member 2 from sliding axially during rotation about the housing 1. This prevents the regulating surface 2b from axially separating from the flow plate 121, thereby preventing the first flow opening 1b from directly communicating with the main flow channel 1a, thereby ensuring the operational reliability of the flow regulating assembly 100.

[0049] The structural form of the elastic member 3 is not particularly limited. The elastic member 3 includes, but is not limited to, a spring, a spring sheet, a bellows, or other elastic structures with recoverable deformation. For example, in one embodiment, referring to Figures 3 and 4 , the housing 1 includes a cover 11 and a sleeve 12. A main flow channel 1a is formed in the sleeve 12. A first flow port 1b and a mounting port 1d are formed at both axial ends of the sleeve 12. The end of the regulating member 2 adjacent to the first flow port 1b extends into the main flow channel 1a through the mounting port 1d. The cover 11 is disposed on the mounting port 1d. A stepped surface 2c is formed on the peripheral side wall of the regulating member 2. The ends of the elastic member 3 are respectively connected to the cover 11 and the stepped surface 2c. Specifically, the connection method between the cover 11 and the sleeve 12 is not particularly limited, including but not limited to clamping, bolt and screw connection, welding, gluing and the like. For example, in one embodiment, please refer to Figure X, the cover 11 includes a cover plate 111 provided at the installation port 1d and a surrounding plate 112 provided around the outer peripheral side of the cover plate 111, the inner peripheral wall of the surrounding plate 112 is formed with an internal thread and the outer peripheral wall of the sleeve 12 is formed with an external thread, and the surrounding plate 112 is threadedly connected to the sleeve 12. The cover 11 and the sleeve 12 are threadedly connected, which can facilitate the disassembly and maintenance of the adjustment member 2 and the elastic member 3. The elastic member 3 can be a compression spring provided on the adjustment member 2, when the two ends of the elastic member 3 are respectively connected to the lower end surface of the cover plate 111 and the step surface 2c, so that the adjustment member 2 and the flow plate 121 are kept in contact. For example, in one embodiment, the inner diameter of the sleeve 12 is between 3 mm and 7 mm; and / or the height of the sleeve 12 in the axial direction is between 14 mm and 20 mm.

[0050] There is no particular limitation on the form in which the adjusting member 2 rotates around the axial direction of the casing 1. The user can manually apply a force to rotate around the axial direction of the casing 1 to operate the adjusting member 2 to rotate, or can operate the adjusting member 2 to rotate through mechanical transmission methods such as threaded engagement, gear engagement, etc., or can control the rotation of the adjusting member 2 through motor drive or other methods.

[0051] Exemplarily, in one embodiment, please refer to Figures 1 and 4, the end of the adjusting member 2 away from the first flow port 1b extends out of the main channel 1a and is formed with an operating portion 21 for cooperating with a tool. Specifically, a through hole 111a is formed on the cover plate 111 of the sleeve 11, and the operating portion 21 extends out of the main channel 1a through the through hole 111a. The operating portion 21 is used to provide a force point for the tool to operate the adjusting member 2 to rotate. The user can directly cooperate with the operating portion 21 through the tool to manually rotate the adjusting member 2. Alternatively, the operating portion 21 can also be directly adapted to the motor, and the adjusting member 2 can be electrically driven by the motor to rotate. The structural form of the operating portion 21 is not particularly limited, please refer to Figure 1, the operating portion 21 is a platform surface formed on the outer peripheral wall of the adjusting member 2. Similarly, the operating portion 21 can also be set to a toothed surface or other special-shaped surface adapted to manual or electric operating tools.

[0052] In one embodiment, referring to Figures 3 and 4 , the regulating member 2 is a cylindrical structure comprising a first rod segment 22 and a second rod segment 23. An adjusting surface 2b and a flow channel 2a are formed at one end of the first rod segment 22. The other end of the first rod segment 22 is connected to the second rod segment 23. A stepped surface 2c is formed between the first and second rod segments 22, 23. An operating portion 21 is formed at the end of the second rod segment 23 distal from the first rod segment 22. Specifically, the first rod segment 22 is used to adjust the flow rate at the first flow port 1b, while the second rod segment 23 is used to sleeve the elastic member 3 and drive the first rod segment 22 to rotate. This arrangement allows for precise flow rate adjustment during the machining of the regulating member 2, requiring only the machining accuracy of the first rod segment 22 to be ensured, thereby reducing the overall machining cost and difficulty of the regulating member 2. Exemplarily, in one embodiment, the height of the first rod segment 22 along the axial direction of the casing 1 is 5 mm to 10 mm; and / or, the outer diameter of the first rod segment 22 is 2.9 mm to 6.9 mm; and / or, the height of the second rod segment 23 along the axial direction of the casing 1 is 15 mm to 20 mm; and / or, the outer diameter of the second rod segment 23 is 3 mm to 5 mm.

[0053] In one embodiment, referring to Figures 3 and 4 , the flow regulating assembly 100 includes a first connector 41 and a second connector 42. The first connector 41 communicates with the first flow port 1b, and the second connector 42 communicates with the second flow port 1c. The first connector 41 extends in the same direction as the axial direction of the housing 1, while the second connector 42 extends perpendicular to the axial direction of the housing 1. Specifically, the first connector 41 and the second connector 42 are both tubular structures with two open ends. The end of the first connector 41 away from the first flow port 1b and the end of the second connector 42 away from the second flow port 1c are both used to connect to external piping. The first connector 41 and the second connector 42 facilitate assembly and docking of external piping. For example, in one embodiment, the axial length of the first connector 41 and the second connector 42 is 5 mm to 10 mm; and / or the inner diameter of the first connector 41 and the second connector 42 is 1 mm to 3 mm; and / or the outer diameter of the first connector 41 and the second connector 42 is 4 mm to 5 mm.

[0054] For example, in one embodiment, referring to Figures 3 and 4 , a guide portion 4a is formed on the outer wall of the first connector 41 at the end away from the first flow port 1b, and / or a guide portion 4a is formed on the outer wall of the second connector 42 at the end away from the second flow port 1c. Specifically, the guide portion 4a includes, but is not limited to, a chamfered or rounded corner. The guide portion 4a further facilitates the assembly and docking of external pipelines.

[0055] In one embodiment, referring to Figures 3 and 4 , the flow control assembly 100 includes a seal 5 , which is interposed between the inner circumferential wall of the main channel 1a and the outer circumferential wall of the regulating member 2 . Specifically, the seal 5 is an annular structure, interferingly fitting between the outer circumferential wall of the second rod segment 23 and the inner circumferential wall of the first sleeve segment. The seal 5 prevents liquid in the main channel 1a from leaking through the mounting opening 1d, restricting liquid entry and exit only through the first and second flow openings 1b and 1c, thereby ensuring reliable flow control.

[0056] For example, in one embodiment, referring to Figures 3 and 4 , a limiting annular groove 2d is formed on either the outer circumferential wall of the adjusting member 2 or the inner circumferential wall of the main flow channel 1a, and the sealing member 5 is embedded in the limiting annular groove 2d. In other words, the limiting annular groove 2d can be provided on the adjusting member 2 or on the inner circumferential wall of the main flow channel 1a. The limiting annular groove 2d is used to define the relative position of the sealing member 5 during the axial rotation of the adjusting member 2 around the housing 1, preventing the sealing member 5 from sliding axially during the rotation of the adjusting member 2, thus preventing the sealing member 5 from falling off, and improving the sealing reliability of the sealing member 5.

[0057] The material of the sealing member 5 includes but is not limited to flexible materials such as rubber, silicone, latex, etc. that are tightly sealed, have certain elasticity and wear resistance.

[0058] In one embodiment, please refer to FIG4 , the width D1 of the flow regulating component 100 perpendicular to the axial direction is 10 mm to 20 mm. Specifically, the width D1 of the flow regulating component 100 perpendicular to the axial direction can take values ​​such as 10 mm, 12 mm, 15 mm, 17 mm, 19 mm, 20 mm, etc. In one embodiment, please refer to FIG4 , the height D2 of the flow regulating component 100 along the axial direction is 20 mm to 30 mm. Specifically, the height D2 of the flow regulating component 100 along the axial direction can take values ​​such as 20 mm, 22 mm, 25 mm, 27 mm, 29 mm, 30 mm, etc. In other words, by reasonably setting the structural dimensions of each component of the flow regulating component 100, the overall width of the flow regulating component 100 perpendicular to the axial direction is not greater than 20 mm, and the overall height of the flow regulating component 100 along the axial direction is not greater than 30 mm. The overall structural dimensions of the existing flow regulating device along a certain direction are usually greater than 80 mm.
