[0031] 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 .

[0032] A main flow channel 1a is formed in the casing 1. A first flow port 1b is formed on one axial side wall of the casing 1, and a second flow port 1c is formed on the circumferential side wall of the casing 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 in Figure 4 as an example, the casing 1 is a roughly hollow tubular structure, and the axial direction is the same as the up-down direction. The first flow port 1b and the second flow port 1c can both be used for docking pipes. The 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.

[0033] At least a portion of the regulating member 2 is disposed within the main flow channel 1a. The regulating member 2 slides axially along the housing 1 to adjust the flow rate of the first flow opening 1b entering the main flow channel 1a. That is, the regulating member 2 can be partially or completely disposed within the main flow channel 1a. For example, the lower end of the regulating member 2 is disposed within the main flow channel 1a and can slide axially relative to the housing 1 to open or close the first flow opening 1b located on the sidewall of the lower end of the housing 1. The regulating member 2 can adjust the distance between the regulating member 2 and the first flow opening 1b to adjust the flow rate of the first flow opening 1b entering the main flow channel 1a.

[0034] The flow regulating assembly 100 can be used in an electronic atomization device 1000. Taking the flow regulating assembly 100 used in the electronic atomization device 1000 according to an embodiment of the present application as an example, refer to FIG6 . Another aspect of the present application provides an electronic atomization device 1000, comprising 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.

[0035] 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 230 are respectively connected to the atomizing chamber 210 and the pump air 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.

[0036] In one embodiment, please refer to Figure 7, 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.

[0037] 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 slide axially along the housing 1 to directly regulate the flow of the first flow port 1b into the main flow 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.

[0038] There is no special limitation on the form in which the adjusting member 2 slides in the axial direction. The user can manually apply a sliding force in the axial direction to operate the adjusting member 2 to slide, or the user can convert the rotational motion into linear motion through mechanical transmission methods such as threaded fitting, worm gear fitting, gear rack fitting, etc. to achieve relative sliding between the adjusting member 2 and the relative housing 1.

[0039] For example, in one embodiment, referring to Figures 4 and 5 , the regulating member 2 has a fully closed position that closes the first flow port 1b and a fully open position that avoids the first flow port 1b in the axial sliding direction of the housing 1. The regulating member 2 is threadedly engaged with the housing 1 so that during the circumferential rotation of the regulating member 2 relative to the housing 1, the regulating member 2 can continuously slide axially relative to the housing 1 between the fully closed position and the fully open position to adjust the liquid outlet area of ​​the first flow port 1b. When the regulating member 2 continuously slides axially relative to the housing 1 between the fully closed position and the fully open position, the liquid outlet area of ​​the first flow port 1b continuously changes as the regulating member 2 slides. Therefore, the flow regulating assembly 100 of the present application can achieve stepless regulation of the flow rate.

[0040] The relative position of the threaded connection between the adjusting member 2 and the housing 1 is not particularly limited. In one embodiment, the adjusting member 2 can be a rod-shaped structure with an external thread on the circumferential side wall, and the inner circumferential wall of the main channel 1a is provided with an internal thread that cooperates with the external thread of the adjusting member 2. The internal thread of the main channel 1a is threadedly engaged with the external thread of the adjusting member 2, so that the adjusting member 2 can rotate circumferentially relative to the sleeve while continuously sliding along the axial direction of the housing 1.

[0041] In one embodiment, referring to Figures 3 and 4 , the adjusting member 2 includes a rod 21 and a cover 22. An installation opening 1d is formed at one axial end of the housing 1 away from the first flow port 1b. One end of the rod 21 extends into the main flow channel 1a through the installation opening 1d. The cover 22 is connected to the axial end of the rod 21 away from the first flow port 1b. The cover 22 includes a cover plate 221 connected to one end of the rod 21 and a surrounding plate 222 disposed around the outer periphery of the cover plate 221. The inner circumferential wall of the surrounding plate 222 is threadedly engaged with the outer circumferential wall of the housing 1. With this arrangement, a user can directly operate the cover 22 to drive the rotation of the entire adjusting member 2. Since the cover 22 is threadedly engaged with the housing 1, the adjusting member 2 will also slide along the axial direction of the housing 1 as a whole during rotation. Specifically, the flow rate adjustment process from small to large is as follows: in the fully closed position, the end of the rod body 21 away from the installation port 1d abuts against the first flow port 1b of the casing 1 to close the connection between the first flow port 1b and the main channel 1a. In the process of switching from the fully open position to the fully open position, the end of the rod body 21 away from the installation port 1d separates from the casing 1 and slides relative to the casing 1 in the axial direction away from the first flow port 1b. The gap between the rod body 21 and the first flow port 1b also gradually increases. Finally, in the fully open position, when the gap between the rod body 21 and the first flow port 1b reaches the maximum value. Exemplarily, in one embodiment, the height of the enclosure 222 along the axial direction of the casing 1 is 6mm to 8mm; and / or the height of the internal thread of the enclosure 222 along the axial direction of the casing 1 is 5mm to 7mm.

[0042] In one embodiment, the thread diameter is M4 to M36. That is, the outer diameter of the thread on the outer peripheral wall of the housing 1 ranges from M4 to M36. Specifically, the outer diameter of the thread on the outer peripheral wall of the housing 1 can be M4, M8, M12, M18, M27, M36, or other values. Specifically, when the user rotates the adjusting member 2 for a certain arc length, a larger thread diameter results in a smaller angle of rotation of the adjusting member 2, a smaller change in flow rate regulation, and a lower adjustment sensitivity. In this case, flow rate regulation is relatively slow and flow rate regulation accuracy is relatively high. Conversely, when the user rotates the adjusting member 2 for a certain arc length, a smaller thread diameter results in a larger angle of rotation, a larger change in flow rate regulation, and a higher adjustment sensitivity. In this case, flow rate regulation is relatively fast. Therefore, the sensitivity of flow rate changes can be adjusted by setting an appropriate thread diameter. Setting the thread diameter to M4 to M36 can achieve an appropriate flow rate regulation sensitivity.

[0043] In one embodiment, the thread pitch is 0.5 mm to 3 mm. The axial distance traveled by any point on the thread during one rotation along the same spiral line is defined as follows: For a given rotation angle of the adjusting member 2, a smaller thread pitch results in a smaller axial sliding distance of the adjusting member 2, a smaller change in flow regulation, and a lower adjustment sensitivity. In this case, flow regulation is relatively slow, and flow regulation accuracy is relatively high. Conversely, for a given rotation angle of the adjusting member 2, a larger thread pitch results in a larger axial sliding distance of the adjusting member 2, a greater change in flow regulation, and a higher adjustment sensitivity. In this case, flow regulation is relatively rapid.

[0044] In one embodiment, the flow regulating assembly 100 includes an elastic member 3. The elastic force of the elastic member 3 is used to ensure tight contact between the threads of the regulating member 2 and the housing 1. In other words, the elastic force generated by the elastic member 3 can maintain close contact between the threaded connection surfaces of the regulating member 2 and the housing 1, effectively preventing thread stripping. This ensures that each time the regulating member 2 rotates at any slight angle relative to the housing 1, the regulating member 2 can slide axially relative to the housing 1, thereby ensuring regulation accuracy.

[0045] The structural form of the elastic member 3 is not particularly limited. The elastic member 3 may include, but is not limited to, a spring, a spring sheet, a bellows, or other elastic structures with recoverable deformation. For example, in one embodiment, as viewed from the perspective of Figure 4 , the inner circumferential wall of the main channel 1a is formed with a stepped surface 1f, and the ends of the elastic member 3 are respectively connected to the cover plate 221 and the stepped surface 1f. Specifically, the elastic member 3 may be a compression spring or a tension spring sleeved on the rod body 21. When the ends of the elastic member 3 are respectively connected to the lower end surface of the cover plate 221 and the stepped surface 1f, they provide an elastic force to maintain the threaded connection surface in close contact.

[0046] For example, in one embodiment, referring to FIG4 , the axial section of the housing 1 between the stepped surface 1f and the first flow port 1b is the first sleeve section 11, and the axial section of the housing 1 between the stepped surface 1f and the mounting opening 1d is the second sleeve section 12. Specifically, the first sleeve section 11 is used to guide the flow at the first flow port 1b, while the second sleeve section 12 is used for threaded connection with the cover 22 and for mounting the elastic member 3. Therefore, the precision of the threaded connection between the second sleeve section 12 and the cover 22 directly affects the accuracy of flow rate regulation. This arrangement allows for fine flow rate regulation during the processing of the housing 1 by only ensuring the processing precision of the second sleeve section 12, thereby reducing the overall processing cost and difficulty of the housing 1. For example, in one embodiment, the height of the first sleeve section 11 along the axial direction of the housing 1 is 14 mm to 20 mm; and / or the outer diameter of the first sleeve section 11 is 5 mm to 8 mm; and / or the inner diameter of the first sleeve section 11 is 3 mm to 4 mm; and / or the height of the second sleeve section 12 along the axial direction of the housing 1 is 8 mm to 12 mm; and / or the outer diameter of the second sleeve section 12 is 8 mm to 12 mm; and / or the inner diameter of the second sleeve section 12 is 5 mm to 8 mm. In other words, the overall structural dimensions of the second sleeve section 12 are larger than those of the first sleeve section 11, thereby facilitating assembly of the rod body 21 and the elastic member 3.

[0047] For example, in one embodiment, referring to Figures 3 and 4 , the rod body 21 is a cylindrical structure comprising a first rod segment 211 and a second rod segment 212. One end of the first rod segment is located near the first flow opening 1b, while both ends of the second rod segment 212 are connected to the cover 22 and the end of the first rod segment 211 located away from the first flow opening 1b. Specifically, the first rod segment 211 is used to adjust the flow rate at the first flow opening 1b, while the second rod segment 212 is used to connect to the cover 22 and the sleeved elastic member 3. This arrangement allows for precise flow rate adjustment during machining of the rod body 21, requiring only the machining accuracy of the first rod segment 211 to be ensured, thereby reducing the overall machining cost and difficulty of the rod body 21. Exemplarily, in one embodiment, the height of the first rod segment 211 along the axial direction of the casing 1 is 5 mm to 8 mm; and / or, the outer diameter of the first rod segment 211 is 2 mm to 4 mm; and / or, the height of the second rod segment 212 along the axial direction of the casing 1 is 10 mm to 14 mm; and / or, the outer diameter of the second rod segment 212 is 3 mm to 5 mm.

[0048] In one embodiment, referring to Figures 3 and 4, a first frustum 1e is formed on the outer peripheral side of the first flow port 1b, the cross-sectional diameter of which gradually increases in the direction away from the first flow port 1b. A second frustum 2a is formed on the peripheral side wall of the adjusting member 2 near one axial end of the first flow port 1b. The first frustum 1e and the second frustum 2a abut against each other to close the first flow port 1b. The first frustum 1e and the second frustum 2a cooperate with each other to ensure that the adjusting member 2 can effectively close the first flow port 1b each time they abut. Compared with a plane abutment perpendicular to the axial direction, the sealing performance is better and the gapless contact between the adjusting member 2 and the housing 1 is better ensured. For example, in one embodiment, the height of the first frustum 1e along the axial direction of the housing 1 is 1 mm to 2 mm.

[0049] 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 pitch of the thread, the diameter of the thread, the shape and size parameters of the first flow port 1b, and the shape and size parameters of the rod body 21.

[0050] 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 3 mm to 5 mm.

[0051] 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.

[0052] 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, interference-fitting between the outer circumferential wall of the second rod segment 212 and the inner circumferential wall of the first sleeve segment 11. 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.

[0053] For example, in one embodiment, referring to Figures 3 and 4 , a limiting annular groove 2b 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 2b. In other words, the limiting annular groove 2b can be provided on the adjusting member 2 or on the inner circumferential wall of the main flow channel 1a. The limiting annular groove 2b is used to define the relative position of the sealing member 5 during the sliding movement of the adjusting member 2 relative to the housing 1, thereby preventing the sealing member 5 from wearing or slipping during the axial reciprocating sliding of the adjusting member 2 along the housing 1, thereby improving the sealing reliability of the sealing member 5.

[0054] 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.

[0055] 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. The overall structural dimensions of the flow regulating component 100 of the present application are smaller and the structure is more compact, and can be applied to a portable electronic atomization device 1000. In addition, the flow regulating component 100 provided in the embodiment of the present application can also be used in micro-flow regulation fields such as syringe flow regulation and physical and chemical analysis tests.

[0056] The flow regulating component 100 provided in the embodiment of the present application reasonably sets the relevant parameters of the flow regulating component 100 within the above-mentioned size range, has a simple and compact structure, can achieve precise regulation within a flow range of no more than 0.1 ml / s, and occupies a small overall space, and can be used in syringe flow regulation, physical and chemical analysis tests and other micro flow regulation fields.
