Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to a liquid supply component and atomizer with a rotary switch. Background Technology

[0002] To meet user needs, existing atomizers offer additional e-liquid supply structures to increase e-liquid storage capacity. These structures include a tank with a reservoir and a switch mechanism to control the e-liquid outlet. The switch mechanism is often a sealing plug inserted into the outlet; moving the plug inwards or outwards opens the outlet, or even puncturing the plug with a wicking element. These outlet opening and closing methods not only make the e-liquid flow uncontrollable but also make them difficult to reuse. Utility Model Content

[0003] The main purpose of this invention is to propose a liquid supply component and atomizer with a rotary switch to solve the problem of uncontrollable oil output in the existing liquid supply structure.

[0004] To achieve the above objectives, in one aspect, this application provides a liquid supply assembly for a rotary switch, the liquid supply assembly comprising:

[0005] Liquid supply tank, with an installation port on one side of the tank body;

[0006] A sealing seat, assembled at the mounting port to cooperate with the liquid supply tank to form a liquid supply chamber for storing liquid, the sealing seat comprising:

[0007] The fixing part has a top wall and a side wall connected to the edge of the top wall. The top wall has an oil outlet on the side facing the liquid supply chamber. The outer wall of the side wall is connected to the inner wall of the mounting port. The top wall has an annular receiving cavity with an opening facing outward on the side away from the liquid supply chamber.

[0008] The movable part includes a ring-shaped enclosure plate that is rotatably mounted in the receiving cavity about the axis of the receiving cavity. The enclosure plate has a sealing part on the side facing the top wall. The outer peripheral wall of the enclosure plate is provided with an upwardly inclined first guide surface. The first guide surface is used to withstand external pressure and convert it into rotational torque to drive the movable part to rotate about the axis, thereby causing the sealing part to rotate to a position that coincides with or is offset from the oil outlet.

[0009] Understandably, in the above embodiments, when the first guide surface of the liquid supply assembly is subjected to external pressure, the movable part is forced to rotate around the axis of the receiving cavity to the inclined side under pressure, thereby causing the sealing part to rotate to a position that coincides with or is offset from the oil outlet; the amount of oil supplied by the liquid supply cavity varies with the proportion of the sealing part coinciding with or offset from the oil outlet.

[0010] In some embodiments, the liquid supply assembly further includes a vent pipe, the liquid supply chamber is provided with a vent that communicates with the outside atmosphere, one end of the vent pipe is connected to the vent, and the other end of the vent pipe passes through the sealing seat to form an air inlet exposed outside the liquid supply chamber and communicating with the outside atmosphere.

[0011] Furthermore, the sidewall includes an outer sidewall and an inner sidewall, the outer sidewall abutting against the inner wall of the mounting port, the inner sidewall forming a mounting hole for the air guide tube to pass through, and the top wall connecting the outer sidewall and the inner sidewall.

[0012] In some embodiments, the oil outlet has a first end face and a second end face at the opening edge facing the liquid supply chamber, wherein the first end face is located on a first horizontal plane, the second end face is located on a second horizontal plane, and the first horizontal plane is lower than the second horizontal plane.

[0013] In some embodiments, at least two sealing portions are provided, and the gap between adjacent sealing portions is used to expose the oil outlet when the movable portion rotates.

[0014] In some embodiments, the sealing portion has a rib protruding into the inner wall of the receiving cavity. When the sealing portion coincides with the oil outlet, the rib abuts against the edge of the oil outlet to seal the oil outlet.

[0015] Furthermore, the receiving cavity is provided with an annular guide rail, and the outer wall of the enclosure is provided with an annular protrusion. The protrusion cooperates with the guide rail to rotatably connect the movable part and the fixed part.

[0016] On the other hand, this application also provides an atomizer, which includes an atomizing component and a liquid supply component as described in any of the above claims. The atomizing component has a second guide surface that mates with the first guide surface. When pressure is applied to the first guide surface through the second guide surface, the movable part rotates and the sealing part coincides with or is offset from the oil outlet. The liquid stored in the liquid supply chamber can flow to the atomizing component through the oil outlet. The atomizing component absorbs and heats the liquid to generate an aerosol.

[0017] In some embodiments, the atomizing assembly includes an atomizing base, which is detachably mounted to the receiving cavity and seals the receiving cavity to form a liquid storage cavity that is communicative to the liquid supply cavity; the atomizing base has a top surface disposed opposite to the first guide surface, and a second guide surface is disposed on the top surface to cooperate with the first guide surface.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. When the atomizing component and the liquid supply component are assembled, the atomizing component applies pressure to the first guide surface through the second guide surface, causing the moving part to rotate to one side around the axis of the receiving cavity under the action of pressure, thereby making the sealing part coincide with or stagger the oil outlet, so as to realize the outflow or sealing of the liquid in the liquid supply cavity.

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. For illustrative purposes, specific structures and details are presented in the description to provide a thorough understanding of the embodiments. Those skilled in the art will readily recognize that some features may be omitted in different circumstances, or may be replaced by their components, materials, or methods. In some cases, to make the described embodiments clear, well-known features are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description, which is not necessary for those skilled in the art to describe these related operations in detail.

[0036] This application provides a liquid supply assembly for a rotary switch, the liquid supply assembly 10 as follows: Figure 1-7 As shown, it includes a liquid supply chamber 11 and a sealing seat 12. The liquid supply chamber 11 has an open side to form an installation port. The sealing seat 12 is fitted into the installation port to seal the open side, so as to form a liquid supply cavity 110 for storing liquid (e-liquid) inside the liquid supply chamber 11.

[0037] The liquid supply chamber 11 can be cylindrical, square, oval, rhomboid, etc. For example, refer to... Figures 2-4 As shown, the liquid supply chamber 11 is roughly cylindrical, with a hollow annular cavity inside, and an open design on one side to form an annular installation port.

[0038] The inner wall of the liquid supply chamber 11 at the installation port is provided with a slot 111, which can be engaged with the sealing seat 12.

[0039] The sealing seat 12 includes a fixed part 120 and a movable part 121. The fixed part 120 is interference-fitted to the mounting port, and the movable part 121 is rotatably connected to the fixed part 120.

[0040] For example, the fixing part 120 is annular, having a top wall D for closing the mounting opening and an annular side wall that abuts against the inner wall of the mounting opening. The side wall is connected to the edge of the top wall D, and the side wall surrounds an annular receiving cavity 1203, which has an axis Z. The side wall and the top wall D can be integrally formed.

[0041] The top wall D is provided with at least one oil outlet 1201, which is connected to the liquid supply chamber 110. For example, the top wall D is provided with at least two arc-shaped oil outlets 1201, which are distributed in a ring on the top wall D.

[0042] In some embodiments, the sidewall includes an outer sidewall B and an inner sidewall C, the outer sidewall B enclosing an annular receiving cavity 1203, the inner sidewall C enclosing an mounting hole 1204, and the top wall D connected to the upper part of the outer sidewall B and the inner sidewall C.

[0043] The outer side of the outer wall B is provided with a protrusion 1202 that engages with the slot 111. The protrusion 1202 engages with the slot 111 to connect and fix the fixing part 120 to the body of the liquid supply chamber 11.

[0044] An annular guide rail 1205 is provided on the inner side of the outer wall B. The guide rail 1205 can support the movable part 121 to rotate around axis Z within the receiving cavity 1203.

[0045] The oil outlet 1201 has an open end face facing the liquid supply chamber 110. See also Figure 4 As shown, the open end face includes a first end face 12010 near the outer side wall B and a second end face 12011 near the inner side wall C, wherein the horizontal plane of the first end face 12010 is lower than the horizontal plane of the second end face 12011. When the bubble flows to the oil outlet 1201, the height difference formed by the first end face 12010 and the second end face 12011 can generate different pulling forces on the bubble, causing the bubble to break.

[0046] The movable part 121 has a shape adapted to the contour of the receiving cavity 1203. The movable part 121 includes a surrounding plate adapted to the annular receiving cavity 1203, the surrounding plate forming a cylindrical structure. The cylindrical surrounding plate is rotatably fitted inside the receiving cavity 1203. The surrounding plate has a sealing part 1211 that abuts against a portion of the inner wall of the receiving cavity 1203 to seal the oil outlet 1201. When the surrounding plate (movable part 121) rotates, the sealing part 1211 can rotate to a position corresponding to the oil outlet 1201 to close the oil outlet 1201, or the sealing part 1211 can rotate to a position offset from the oil outlet 1201 to expose the oil outlet 1201. Figure 3 As shown, the cross-section of the sealing part 1211 is arc-shaped, and its arc length is greater than or equal to the arc length of the oil inlet 220.

[0047] A sealing part 1211 is protrudingly disposed on the side of the enclosure plate corresponding to the oil outlet 1201. The number of sealing parts 1211 corresponds to the number of oil outlets 1201, and the gap 1212 between adjacent sealing parts 1211 is greater than or equal to the opening size of the oil outlet 1201. When any sealing part 1211 coincides with an oil outlet 1201, the sealing parts 1211 at other positions should also coincide with the oil outlets 1201 at their corresponding positions.

[0048] For example, the top wall D of the fixing part 120 is provided with two arc-shaped oil outlets 1201, and the surrounding plate is provided with only two arc-shaped sealing parts 1211, the arc length of the sealing part 1211 being greater than the arc length of the oil outlet 1201.

[0049] See Figure 5 The movable part 121 (enclosure) rotates around axis Z to a position where it is blocked by the top wall D of the fixed part 120. The sealing part 1211 is covered (blocked) by the top wall D. The sealing part 1211 and the oil outlet 1201 are completely misaligned. The gap 1212 between the two sealing parts 1211 exposes the oil outlet 1201, and the liquid stored in the liquid supply chamber 110 can flow out from the oil outlet 1201.

[0050] See Figure 6 The movable part 121 (enclosure) rotates around axis Z to a position partially blocked by the top wall D of the fixed part 120. A portion of the sealing part 1211 is covered (blocked) by the top wall D. The sealing part 1211 abuts against the inner wall of the receiving cavity 1203 near the oil outlet 1201, causing part of the oil outlet 1201 to be exposed and partially blocked by the sealing part 1211. The liquid flow rate from the oil outlet 1201 is less than... Figure 5 The state shown.

[0051] See Figure 7 The movable part 121 (enclosure) rotates around axis Z to a position where it is partially covered or not covered by the top wall D of the fixed part 120. Both ends of the sealing part 1211 are covered by the top wall D, while the other parts are exposed from the oil outlet 1201. The sealing part 1211 abuts against the inner wall of the receiving cavity 1203 near the oil outlet 1201. The sealing part 1211 completely seals the oil outlet 1201, preventing liquid from flowing out through the oil outlet 1201, and the liquid supply cavity 110 is in a closed state.

[0052] The sealing part 1211 can completely abut against the inner wall of the receiving cavity 1203, but the increased contact area will increase the rotational resistance of the movable part 121. See also Figure 3As shown, a rib 12110 is protruding from the sealing part 1211, protruding from the outer wall, top wall D, and inner wall of the upper part of the enclosure plate. When the movable part 121 is assembled into the receiving cavity 1203, the rib 12110 abuts against the inner wall of the receiving cavity 1203, forming a closed annulus with a shape similar to that of the oil outlet 1201, and the annulus formed by the rib 12110 is larger than that of the oil outlet 1201. When the sealing part 1211 rotates with the movable part 121 to a position coinciding with the oil outlet 1201, the rib 12110 abuts against the inner wall of the receiving cavity 1203 at the oil outlet 1201, sealing the oil outlet 1201.

[0053] The rotatable connection between the enclosure and the receiving cavity 1203 includes various methods. For example, see... Figure 9 As shown, the outer side of the enclosure is provided with a protrusion 1214 that slides with the guide rail 1205. The protrusion 1214 is engaged within the guide rail 1205 on the inner wall of the receiving cavity 1203. The enclosure can rotate around the axis Z along the annular guide rail 1205 within the guide rail 1205 via the protrusion 1214, and the contact area between the enclosure and the fixed part 120 can be reduced, thereby reducing the rotational resistance of the movable part 121.

[0054] The protrusion 1214 can be a complete ring structure or a multi-segmented, ring-shaped protrusion. See also Figure 3 As shown, the outer perimeter wall of the enclosure is provided with a protruding arc-shaped protrusion 1214.

[0055] The movable part 121 can be operated externally and rotates around axis Z within the receiving cavity 1203.

[0056] In some embodiments, the lower part of the enclosure is provided with an operating position for receiving external operations. For example... Figure 3 As shown, the lower part of the enclosure is provided with an operating port, which has a first guide surface 1213 extending obliquely, and the first guide surface 1213 is inclined towards the upper part of the enclosure. Exemplarily, when the first guide surface 1213 is subjected to longitudinal pressure applied to the enclosure, the enclosure converts the pressure into rotational torque, and the enclosure rotates about axis Z to the side away from the first guide surface 1213.

[0057] The operating port is roughly triangular in shape, with its hypotenuse being the first guide surface 1213.

[0058] In some embodiments, the liquid supply assembly 10 may form a mouthpiece for the user to aspirate, and the liquid supply assembly 10 may be provided with an air passage for gas to pass through. For example, see... Figure 2As shown, the liquid supply chamber 11 has an air outlet 113 on one side of the chamber body, and an air guide pipe 112 connected to the air outlet 113 on the side opposite to the air outlet 113. The air guide pipe 112 passes through the liquid supply chamber 110 and is connected to the atomizing component 20 of the atomizer, so that the aerosol and air generated by the atomizing component 20 can pass through the air guide pipe 112 and be discharged from the air outlet 113.

[0059] Specifically, the air guide tube 112 passes through a mounting hole 1204 located at the top of the fixing part 120. After passing through the mounting hole 1204, the air inlet end of the air guide tube 112 is exposed within the receiving cavity 1203. Understandably, the air guide tube 112 and the mounting hole 1204 are interference-fitted to prevent liquid from leaking out through the gap 1212 between the air guide tube 112 and the mounting hole 1204. The inner wall C of the fixing part 120 surrounds the mounting hole 1204, forming an inner wall that abuts against the outer wall of the air guide tube 112.

[0060] See Figures 8 to 11 As shown, this application also provides an atomizer, which includes an atomizing component 20 and a liquid supply component 10 as described in the above embodiments, wherein the liquid supply component 10 is detachably connected to the atomizing component 20.

[0061] The atomizing assembly 20 includes an atomizing base 21, which is fitted into the receiving cavity 1203 of the liquid supply assembly 10. When the atomizing base 21 is fitted into the receiving cavity 1203, the atomizing base 21 closes the receiving cavity 1203 and defines a liquid storage cavity 200 between itself and the fixing part 120.

[0062] See Figure 10 As shown, the atomizing base 21 includes a top surface and an annular side surface connected to the edge of the top surface. The side surface is connected to the inner wall of the receiving cavity 1203, and the top surface corresponds to the top wall D of the fixing part 120. The top surface is provided with a number of second guide surfaces 23 equal to the number of first guide surfaces 1213, and each second guide surface 23 cooperates with a corresponding first guide surface 1213.

[0063] The inclined surface of the second guide surface 23 extends in a spiral shape and has an inclination that fits with the first guide surface 1213.

[0064] For example, when the atomizing base 21 is engaged with the liquid supply assembly 10 along the Z-axis, the second guide surface 23 applies axial pressure to the first guide surface 1213. The first guide surface 1213 converts the pressure into rotational torque. The movable part 121 rotates around the Z-axis within the receiving cavity 1203 on the side opposite to the first guide surface 1213. The relative position of the sealing part 1211 and the oil outlet 1201 changes with the rotation of the movable part 121. (Reference) Figures 5 to 7The fixed part 120 and the movable part 121 are shown in three position states. The liquid supply chamber 110 and the liquid storage chamber 200 can be kept in a connected or disconnected state. In the connected state, the oil output of the oil outlet 1201 is also affected by the overlap ratio between the sealing part 1211 and the oil outlet 1201.

[0065] The atomizing assembly 20 also includes an atomizing tube 22. One end of the atomizing tube 22 is axially inserted into the atomizing base 21 and communicates with the external atmosphere. The other end of the atomizing tube 22 is connected to the air guide tube 112 after the atomizing assembly 20 and the liquid supply assembly 10 are assembled. The atomizing tube 22 defines the atomizing chamber of the atomizing assembly 20. The tube wall of the atomizing tube 22 is provided with an oil inlet 220, and the atomizing chamber communicates with the liquid storage chamber 200 through the oil inlet 220. Liquid enters the atomizing chamber through the oil inlet 220 and is atomized by the atomizing core disposed in the atomizing chamber to form an aerosol.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
