Description

Technical Field

[0001] This application relates to the field of aerosol supply, and more particularly to a cover for an aerosol supply system and an aerosol supply system. Background Technology

[0002] An aerosol supply system generates aerosols by atomizing aerosol-generating materials through electrical heating. The system includes a nozzle for passing the aerosol through which the user draws the generated aerosol into their mouth.

[0003] The nozzles of known aerosol supply systems are in an open position. When the system is idle, dust, dirt, and other contaminants can easily enter through the open nozzle. On one hand, these contaminants may cause poor electrical contact in the system's components, affecting its power supply and consequently its heating and atomization efficiency. On the other hand, these contaminants may be inhaled along with the generated aerosol, potentially impacting the user's health or vaping experience. Utility Model Content

[0004] This application aims to at least address one of the technical problems existing in the prior art. To this end, embodiments of this application propose a cover for an aerosol supply system and an aerosol supply system, with the intention of protecting the nozzle by the cover during the idle period of the aerosol supply system, preventing contaminants such as dust and dirt from entering the aerosol supply system through the nozzle and causing contamination.

[0005] In a first aspect, this application discloses a cover for an aerosol supply system, the aerosol supply system including a nozzle having an outlet channel for aerosol output and an outlet located near the end of the outlet channel; the cover is configured to cover or open the outlet.

[0006] By setting a cover that can either cover or open the nozzle's air outlet, the aerosol supply system can be used to cover the nozzle during idle periods, preventing dust, dirt, and other contaminants from entering the system. During use, the cover can be removed to open the air outlet for normal suction.

[0007] In at least some embodiments of this application, the cover has a receiving cavity configured to receive and conceal the suction nozzle within the cover.

[0008] In at least some embodiments of this application, one end of the receiving cavity has an opening for the suction nozzle to be inserted into the receiving cavity through the opening and concealed within the cover. Based on this configuration, an insertable cover is provided, which allows for convenient covering or opening of the suction nozzle's outlet through an insertion and removal operation between the suction nozzle and the receiving cavity.

[0009] In at least some embodiments of this application, the cover further includes a first connecting structure configured to secure the suction nozzle inserted into the receiving cavity. Secured by the first connecting structure, the suction nozzle is prevented from detaching from the receiving cavity.

[0010] In at least some embodiments of this application, the first connecting structure is installed in the receiving cavity.

[0011] In at least some embodiments of this application, the cover includes a cover body and a bracket connected to the cover body, wherein a first mounting structure is disposed on the bracket.

[0012] In at least some embodiments of this application, the bracket is installed in the cover body by one or more of the following methods: gluing, welding, snap-fitting, or interference fit.

[0013] In at least some embodiments of this application, the bracket has multiple elastic portions that are interference-fitted with the cover body.

[0014] In at least some embodiments of this application, the bracket is provided with one of a slot and a protrusion, and the cover body is provided with the other of a slot and a protrusion. The bracket is installed on the cover body by the snap-fit ​​of the protrusion and the slot.

[0015] In at least some embodiments of this application, the bracket is provided with one of a locking platform and a protrusion, and the cover body is provided with the other of a locking platform and a protrusion. The locking platform and the protrusion are engaged in the longitudinal axis direction of the cover to install the bracket on the cover body.

[0016] In at least some embodiments of this application, the first connection structure is magnetic, and is used to magnetically engage with the suction nozzle.

[0017] In at least some embodiments of this application, the first connection structure includes one or more first magnetic elements.

[0018] In at least some embodiments of this application, the cover includes a cover body and a bracket connected to the cover body and configured to mount a first magnetic element, the bracket being configured to be at least partially located in a receiving cavity.

[0019] In at least some embodiments of this application, the bracket is provided with one or more grooves configured to mount the first magnetic member. Mounting the first magnetic member via the grooves makes it easier to secure the first magnetic member and saves installation space on the bracket.

[0020] In at least some embodiments of this application, at least one groove forms a limiting space with the inner wall of the cover body, and the first magnetic suction member is installed within the limiting space. The limiting space can fix the first magnetic suction member and prevent it from sliding out of the receiving cavity.

[0021] In at least some embodiments of this application, the support is an annular support surrounding the receiving cavity, and at least one groove is provided on the outer peripheral wall of the support.

[0022] In at least some embodiments of this application, the grooves are at least two in number and are spaced apart circumferentially along the outer peripheral wall of the bracket. Each groove forms a limiting space with the inner wall of the cover body, and a first magnetic suction member is installed in each limiting space. By circumferentially spaced the first magnetic suction members, a more uniform magnetic force can be provided in the circumferential direction, so as to fix the suction nozzle more stably in the receiving cavity.

[0023] In at least some embodiments of this application, the groove has an insertion port facing the opening, the insertion port being configured for insertion of a first magnetic member. By providing the insertion port, the first magnetic member can smoothly enter the groove.

[0024] In at least some embodiments of this application, a support plate is mounted on the bracket, the support plate conforming to the insertion port and supporting the first magnetic member within the groove. The support plate supports and prevents the first magnetic member from falling out of the insertion port.

[0025] In at least some embodiments of this application, the bracket is an annular bracket surrounding a receiving cavity. The end of the bracket near the opening has a flange edge extending inwards towards the bracket. The inner peripheral wall of the bracket has one or more elastic elements inclined inwards towards the bracket along the direction towards the opening. A receiving space is formed between the flange edge and the elastic elements, and a first magnetic member is installed within the receiving space. Based on this configuration, when the first magnetic member moves from the end of the bracket away from the opening towards the end near the opening into the receiving space, it passes through and compresses the elastic elements, causing the elastic elements to move outwards from the bracket. This allows the first magnetic member to pass through the location of the elastic elements and enter the receiving space until it reaches the flange edge. The flange edge forms a limiting element that restricts the first magnetic member from continuing to move towards the opening. After the first magnetic member enters the receiving space, the elastic elements reset, i.e., the elastic elements incline inwards towards the bracket along the direction towards the opening, forming a limiting element that restricts the first magnetic member from moving away from the opening.

[0026] In at least some embodiments of this application, the elastic element is an integrally formed annular elastic element, or multiple elastic elements are spaced apart along the inner peripheral wall of the bracket.

[0027] In at least some embodiments of this application, the first connection structure includes a first elastic gripper that provides elastic gripping force for gripping the nozzle.

[0030] In at least some embodiments of this application, the bracket has an elastic wall that forms a first elastic gripper and frictionally contacts the nozzle for an interference fit.

[0031] In at least some embodiments of this application, the first connection structure includes a connecting pin configured to be inserted from the outlet of the nozzle into the outlet channel of the nozzle.

[0032] In at least some embodiments of this application, the connecting pin is configured to seal the outlet channel when inserted. The connecting pin simultaneously seals the outlet channel and connects the nozzle to the cap, thus simplifying the cap's structure. Sealing the outlet channel prevents or reduces the leakage of condensate from the outlet within the aerosol supply system.

[0033] In at least some embodiments of this application, the connecting pin is interference-fitted with the nozzle to provide a seal.

[0034] In at least some embodiments of this application, the connecting pin has a raised edge, which seals the nozzle.

[0035] In at least some embodiments of this application, the cover includes a cover body and a bracket, with a connecting pin mounted on the bracket.

[0036] In at least some embodiments of this application, a connecting pin is mounted on a bracket, the connecting pin has an insertion groove, the cover body has a pin that matches the insertion groove, and the bracket is mounted on the cover body through the insertion groove and the pin.

[0037] In at least some embodiments of this application, the cover also includes a sealing pin configured to be inserted into the vent passage to seal the vent passage.

[0038] In at least some embodiments of this application, the cover includes a movable component configured to switch between a covered position and an uncovered position via a preset movement pattern.

In some embodiments, the carrier includes a receptor. In some embodiments, the receptor is embedded within the material. In some alternative embodiments, the receptor is located on one or both sides of the material.

[0129] Consumables

[0130] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0131] receptors

[0132] A sensor is a material that can be heated by being penetrated by a changing magnetic field (such as an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0133] Aerosol Modifier

[0134] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. Aerosol modifiers can be disposed in aerosol modifier release components operable to selectively release the aerosol modifier. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0135] Aerosol generator

[0136] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0137] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0138] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge parts. Typically, the replaceable cartridge part will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power supply) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0139] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on aerosol delivery systems that are operatively configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0140] Example 1

[0141] Figure 1 and 2 An aerosol supply system according to at least some embodiments of this application is shown. For example... Figure 1 and 2 As shown, the aerosol supply system 10 includes a main body 13. The main body 13 includes a proximal end 11 and a distal end 12 disposed opposite to each other along its own length direction.

[0142] Between the proximal end 11 and the distal end 12, the main body 13 also includes a liquid reservoir 14, an atomizer 15, a controller 16, and a battery 17. The liquid reservoir 14 is configured to store liquid or gel-state aerosol-generating material. The atomizer 15 is configured to heat and atomize the aerosol-generating material to produce an aerosol. Specifically, the atomizer 15 may include a heating element and a liquid guide. The liquid guide is configured to deliver the aerosol-generating material in the liquid reservoir 14 to the heating element. The heating element is configured to be electrically energized to atomize the aerosol-generating material; specifically, a metal heating mesh may be selected. The battery 17 is configured to supply power to the atomizer 15, thereby energizing and heating the heating element in the atomizer 15. The controller 16 is configured to control the power supply from the battery 17 to the atomizer 15, such as controlling the on / off state of the power supply from the battery 17 to the atomizer 15, or controlling the magnitude of the power supplied by the battery 17 to the atomizer 15.

[0143] In one embodiment, the main body 13 is generally elongated, with the liquid reservoir 14, atomizer 15, controller 16, and battery 17 arranged sequentially along the direction extending from the proximal end 11 to the distal end 12 of the main body 13. It is understood that in alternative embodiments, the main body 13 may be arranged in other shapes, such as a box shape. The liquid reservoir 14, atomizer 15, controller 16, and battery 17 may also be arranged in other positional relationships.

[0144] like Figure 1 and 2As shown, the aerosol supply system 10 has a nozzle 18 at its proximal end 11. The nozzle 18 has an outlet channel 181 through which the aerosol passes and an outlet 182 located at the outlet end of the outlet channel 181. The aerosol generated by the atomizer 15 heating and atomizing the aerosol generating material is delivered to the outlet channel 181 and inhaled by the user through the outlet 182.

[0145] Contaminants can easily enter the aerosol supply system through the outlet 182 of the nozzle 18, causing contamination. Therefore, this application provides a cover for the aerosol supply system 10 and an aerosol supply system 10 including the cover. The cover can either cover or open the outlet 182 to prevent contaminants from entering when the aerosol supply system 10 is idle, and to open the outlet 182 when the aerosol supply system 10 is in use, allowing the user to perform normal suction.

[0146] The cover for the aerosol supply system 10 can have a variety of possible structures. The following will describe in detail the insert-type cover and the telescopic movable cover through specific embodiments and accompanying drawings.

[0147] Figures 3 to 14 The specific structure of the insert-type cover 20 is shown. For example... Figures 3 to 14 As shown, the so-called insertable cover 20 refers to a cover with a receiving cavity 21 for inserting the nozzle 18. Specifically, one end of the receiving cavity 21 has an opening 22, through which the nozzle 18 can be inserted into the receiving cavity 21 or removed from the receiving cavity 21. Understandably, based on the insertable cover 20, the user can cover or open the nozzle's outlet through a simple insertion and removal operation. Specifically, when the aerosol supply system is not in use, the nozzle 18 is inserted into the receiving cavity 21 through the opening 22 to conceal the nozzle's outlet 182 within the receiving cavity 21. When the aerosol supply system needs to be used, the nozzle is pulled out from the opening 22 to expose the nozzle's outlet 182. Figure 15 The illustration shows the aerosol supply system 10 with its nozzle 18 inserted into the receiving cavity 21 through the opening 22 and then hidden inside the receiving cavity 21. Figure 16 The illustration shows the situation after the nozzle 18 of the aerosol supply system 10 is removed from the receiving cavity 21 through the opening 22.

[0148] To facilitate the smooth insertion and removal of the suction nozzle 18 from the receiving cavity 21, the opening 22 may be configured to have a shape adapted to the suction nozzle 18. For example, if the cross-section of the suction nozzle 18 is circular, the cross-section of the opening 22 may also be circular. The opening 22 may include an inclined guide surface configured to guide the suction nozzle 18 smoothly into or out of the receiving cavity 21. It is understood that the opening 22 may simultaneously have a shape adapted to the suction nozzle 18 and an inclined guide surface.

[0149] In this embodiment, the cover 20 can open the air outlet 182 of the suction nozzle 18 in various ways. In one embodiment, the cover 20 is configured to remain connected to the body 13 of the aerosol supply system 10 even when the suction nozzle 18 is pulled out of the receiving cavity 21 of the cover 20. Understandably, in this manner, the cover 20 is less likely to be lost. In another implementation, the cover 20 is flip-type and rotatably connected to the aerosol supply system 10. When the cover 20 is flipped to the covered position, the suction nozzle 18 is received inside the receiving cavity 21, thereby covering the air outlet 182. When the cover 20 is flipped to the uncovered position, the suction nozzle 18 is moved out of the receiving cavity, thereby opening the air outlet 182.

[0150] In another alternative embodiment, the cap 20 is configured to completely separate from the body 13 of the aerosol supply system 10 when the nozzle 18 is pulled out of the receiving cavity 21 of the cap 20. The manner in which complete separation can be achieved is described below.

[0151] To prevent the nozzle 18 from slipping out of the receiving cavity 21, such as Figures 3 to 14 As shown, the cover 20 includes a first connecting structure 23 for securing the nozzle inserted into the receiving cavity 21. The first connecting structure 23 is configured to be detachable so that the cover 20 is completely separated from the body 13 of the aerosol supply system 10 when the nozzle 18 is removed from the receiving cavity 21. When the nozzle 18 is inserted into the receiving cavity 21, the cover 20 is connected to the nozzle 18 via the first connecting structure 23. When the nozzle 18 is removed from the receiving cavity 21, the cover 20 is completely separated from the nozzle 18 and no longer maintains a connection. By way of example and not limitation, the detachable connection method includes, but is not limited to, magnetic attraction, snap-fit, interference fit, and elastic connection.

[0152] Understandably, the cap 20, once detached from the nozzle 18, is easily lost. Therefore, in a further embodiment of this application, the cap 20 includes a second connecting structure configured to engage with a distal end of the aerosol supply system. For example... Figure 17 This illustrates the configuration where the cap 20 is connected to the distal end 12 of the aerosol supply system 10. Specifically, the second connection structure can be a detachable connection structure that detachably connects the cap 20 to the distal end 12. Through the detachable first and second connection structures, when the aerosol supply system 10 is in use, the cap 20 can be removed from the nozzle 18 and installed on the distal end 12 to prevent loss; when the aerosol supply system 10 is idle, the cap 20 can be removed from the distal end 12 and installed on the nozzle 18 to cover the outlet 182 to prevent contamination.

[0153] In one optional embodiment, the first connecting structure 23 is also the second connecting structure, meaning the cover 20 is detachably connected to the nozzle 18 and the distal end 12 via the same connecting structure. In another optional embodiment, the first connecting structure 23 and the second connecting structure are independently configured, and their connection methods or specific structures are the same, such as both using magnetic attraction. In yet another optional embodiment, the first connecting structure 23 and the second connecting structure are independently configured, and their connection methods or specific structures are different. For example, the first connecting structure 23 uses an interference fit connection, while the second connecting structure uses a magnetic attraction.

[0154] The following description uses a detachable connection as an example to further describe the first connecting structure 23. It should be noted that when the cover 20 includes a second connecting structure, the description of the first connecting structure 23, except for the connecting pin method, also applies to the second connecting structure. For example, the second connecting structure can be a second magnetic suction element that is the same as or similar to the first magnetic suction element, or a second elastic gripper that is the same as or similar to the first elastic gripper. The difference is that the second connecting structure does not fix the suction nozzle 18, but rather the distal end 12 inserted into the receiving cavity 21.

[0155] The first connecting structure 23 can be positioned anywhere on the cover 20 as needed. For example... Figures 3 to 14 As shown, the first connecting structure 23 is installed in the receiving cavity 21. Understandably, this arrangement of the first connecting structure avoids exposure, making the cover 20 and the aerosol supply system 10 more aesthetically pleasing. Furthermore, it allows the suction nozzle 18 to be simultaneously installed and fixed when inserted into the receiving cavity 21, simplifying the nozzle fixing process. Of course, in alternative configurations, the first connecting structure can be located outside the receiving cavity 21 of the cover 20, for example, on the end face of the cover 20 with the opening 22.

[0156] The first connecting structure 23 can be installed on any part of the cover 20 as needed. For example... Figures 3 to 14 As shown, the cover 20 includes a cover body 24 defining a receiving cavity 21. In one optional embodiment, a first connecting structure 23 may be disposed on the cover body 24, such as on the inner wall of the cover body 24. Specifically, the first connecting structure 23 may be disposed on the inner wall of the cover body 24 by means of welding, snap-fitting, etc. The first connecting structure 23 may also be wholly or partially embedded in the cover body 24.

[0157] It is understandable that the overall size of the cover is generally small, therefore, it is somewhat difficult to directly install the first connecting structure 23 on the inner wall of the cover body 24. Therefore, this application provides... Figures 4 to 14 The first connection structure 23 is installed as shown. (As illustrated...) Figures 4 to 14As shown, the cover 20 includes a cover body 24 and a bracket 25 connected to the cover body 24. The bracket 25 is configured to be at least partially located in the receiving cavity 21. A first connecting structure 23 is mounted on the bracket 25. In this way, it is only necessary to install the first connecting structure 23 on the bracket 25 in advance, and then install the bracket 25 in the receiving cavity 21. Compared with installing the first connecting structure 23 directly on the inner wall of the cover body 24, the difficulty of installing the first connecting structure 23 in the receiving cavity is reduced.

[0158] The support 25 can be of any feasible shape, such as a plate-shaped support or an annular support surrounding the receiving cavity 21. The annular support can be a closed annular support, which can be integrally formed or formed by splicing multiple annular support segments. The annular support can also be a non-closed annular support, which can be integrally formed or formed by splicing multiple annular support segments. This application does not impose specific limitations in this regard.

[0159] The bracket 25 can be connected to the cover body 24 via either a detachable or non-detachable connection, as needed. By way of example and not limitation, the bracket 25 can be connected to the cover body 24 via one or more of the following methods: gluing, welding, snap-fit, pin connection, or interference fit. In one such method, such as... Figures 4 to 6 As shown, the cover body 24 can be sleeved outside the bracket 25. The outer peripheral wall of the bracket 25 has one or more elastic portions 257, and is interference-fitted with the inner peripheral wall 241 of the cover body 24 through the elastic portions 257. In another embodiment, as... Figures 7 to 9 As shown, the bracket 25 has a slot 258, and the cover body 24 has a first protrusion 243. The bracket 25 is mounted on the cover body 24 by the engaging engagement of the first protrusion 243 and the slot 258. It is understood that the slot 258 can be provided on the cover body, and the first protrusion 243 can be provided on the bracket 25, which will also allow the bracket 25 to be mounted on the cover body 24. In another embodiment, the bracket 25 may have a locking platform, and the cover body 24 may have a second protrusion. The bracket 25 is mounted on the cover body 24 by the engaging engagement of the locking platform and the second protrusion along the longitudinal axis of the cover. It is understood that the locking platform can be provided on the cover body 24, and the second protrusion can be provided on the bracket 25, which will also allow the bracket 25 to be mounted on the cover body 24.

[0160] Understandably, when there are multiple first connecting structures 23, some of the first connecting structures 23 can be installed on the cover body 24, and other parts of the first connecting structures 23 can be installed on the bracket 25.

[0161] The following provides exemplary descriptions of several specific connection methods for the detachable first connection structure 23.

[0162] like Figures 4 to 14 In the illustrated embodiment, the first connecting structure 23 includes a magnetic attraction mechanism. The magnetic attraction requires mutual cooperation; that is, the suction nozzle 18 needs to be provided with a magnetic attraction structure that cooperates with the first connecting structure 23 to fix the suction nozzle 18 within the receiving cavity 21. The first connecting structure 23 can be an active magnetic attraction component capable of attracting other objects, such as a magnet. The first connecting structure 23 can also be a passive magnetic attraction component capable of being attracted, such as a metal part. It is understood that at least one of the first connecting structure 23 and the magnetic attraction structure on the suction nozzle 18 is an active magnetic attraction component capable of attracting other objects.

[0163] The first magnetic connection structure 23 may specifically include one or more first magnetic elements 231. When the first connection structure 23 includes multiple first magnetic elements 231, all of the first magnetic elements 201 may be active magnetic elements, all of them may be passive magnetic elements, or some of the first magnetic elements 231 may be active magnetic elements and some of them may be passive magnetic elements.

[0164] The first magnetic component 231 can be configured into a corresponding shape as needed, such as a ring, strip, column, or sheet. In a specific embodiment, the first magnetic component 231 can be selected to match the shape of the mounting location. For example, the shape of the first magnetic component 231 may match the shape of the groove described later.

[0165] As described above regarding the first connecting structure 23, the first magnetic member 231 can be disposed at any possible location on the cover 20, or on any possible component of the cover 20, as needed. The following description uses the example of the first magnetic member 231 being disposed on the bracket 25 as an example.

[0166] like Figure 5 , Figure 6 as well as Figures 10 to 13 As shown, the bracket 25 has one or more grooves 251, and the first magnetic member 231 is installed in the groove 251. It is understood that the grooves 251 can be formed at any location on the bracket 25, such as the inner circumferential wall, outer circumferential wall, end face, etc. The grooves 251 can also be arranged in any possible configuration, such as circumferential arrangement, axial arrangement, or random arrangement. The grooves 251 can also be of any shape, such as annular grooves, cylindrical grooves, strip grooves, etc. Figure 5In the illustrated embodiment, the bracket 25 is an annular bracket with an outer peripheral wall and an inner peripheral wall. Multiple grooves 251 are spaced apart circumferentially on the outer peripheral wall. These spaced-apart grooves define circumferentially spaced first magnetic suction members 231. The spaced-apart first magnetic suction members 231 provide a more uniform magnetic attraction force in the circumferential direction, thus more stably fixing the suction nozzle 18 within the receiving cavity 21. In addition to the spaced arrangement of multiple grooves 251, in optional embodiments of this application, annular grooves 251 arranged along the entire circumference can also be formed on the outer peripheral wall to define the first magnetic suction members 231 arranged along the entire circumference, thereby providing a continuous and uniform magnetic attraction force in the circumferential direction.

[0167] like Figure 5 , Figure 11 In the illustrated embodiment, the groove 251 is formed on the outer peripheral wall of the bracket 25, and the opening 2511 of the groove 251 faces the inner peripheral wall 241 of the cover body 24, and the opening 2511 of the groove 251 is set close to the inner peripheral wall 241 of the cover body 24. This makes the inner peripheral wall 241 of the cover body 24 and the groove 251 form a limiting space, restricting the first magnetic member 231 from sliding out of the opening 2511.

[0168] Figures 10 to 12 In the illustrated embodiment, the groove 251 is an annular groove extending circumferentially along the bracket 25, and has a large opening 2511, allowing the first magnetic member 231 to be easily installed into the groove 251 from the opening 2511. Figures 4 to 6 In the illustrated embodiment, the groove 251 is a cylindrical groove extending along the length of the bracket 25, and the opening 2511 is relatively small, making it difficult for the first magnetic member 231 to enter the groove 251 from the opening 2511. Therefore... Figure 6 In the illustrated embodiment, the groove 251 is further provided with an insertion port 2512 having an overhanging opening 22, so that the first magnetic member 231 enters the groove 251 through the insertion port 2512. To prevent the first magnetic member 231 from sliding out of the groove 251 from the insertion port 2512, the cover 20 may also include one or more support pieces 26 that conform to the insertion port 2512 to support the first magnetic member 231 within the groove 251. Correspondingly Figures 4 to 6 The cover 20 can be provided with multiple circumferentially spaced support pieces 26, each support piece 26 supporting one groove 251. In an alternative embodiment, the cover 20 can also be provided with a single support piece 26 that is arranged around the entire circumference.

[0169] This application embodiment also provides another bracket 25 for mounting the first magnetic member 231. For example... Figures 7 to 9 As shown, the cover 20 includes a cover body 24 and a support 25. The support 25 is an annular support with a cavity 252 and openings at both ends. Figures 4 to 6 , Figures 8 to 10 The bracket 25 shown differs in that it has a flange edge 254 extending toward the cavity 252 of the bracket 25 at the end near the opening 22, and one or more elastic elements 253 are provided on the inner peripheral wall 255 of the bracket 25. Each elastic element 253 has a free end 2531 and a fixed end 2532, wherein the free end 2531 is positioned near the opening 22 relative to the fixed end 2532 and is inclined toward the cavity 252 relative to the fixed end 2532. In this configuration, by adjusting the size of the first magnetic member 231, when the first magnetic member 231 enters the cavity 252 from the end of the bracket 25 away from the opening 22, it passes through and presses the elastic element 253 outwards along the cross-sectional direction of the bracket 25. The pressed free end 2531 deforms outwards from the bracket 25, thereby causing the first magnetic member 231 to pass through the elastic element 253 and continue moving toward the flange edge 254 until it contacts the flange edge 254. After the external force on the elastic member 253 disappears, the free end 2531 will reset. The reset free end 2531 will tilt back towards the cavity 252 and together with the flange edge 254 and the inner peripheral wall 255 between them, form a limiting receiving space, restricting the first magnetic member 231 from moving out of the receiving space.

[0170] The elastic element 253 can be one in number, specifically a one-piece molded annular elastic element or a non-annular elastic element. The elastic element 253 can also be multiple, and can be distributed circumferentially.

[0171] Unlike the magnetic attraction methods mentioned above, such as Figures 4 to 6 , Figure 8 As shown, the first connection structure 23 may include a first elastic gripper 232 that provides elastic gripping force. The first elastic gripper 232 is configured to hold the nozzle 18 by elastic deformation when the nozzle 18 is inserted into the receiving cavity 21.

[0172] Referring to the previous description of the first connecting structure 23, the first elastic gripper 232 can be set at any possible location on the cover 20 as needed, or it can be set on any possible component of the cover 20 as needed.

[0173] In optional embodiments, such as Figure 8 As shown, the first elastic gripper 232 is disposed on the cover body 24.

[0174] In another alternative embodiment, the first elastic gripper 232 may also be disposed on the bracket 25. The bracket 25 has an inner peripheral wall and an outer peripheral wall, wherein the inner peripheral wall is at least partially elastic, through which the first elastic gripper 232 is formed and frictionally contacts the suction nozzle 18 to allow for an interference fit mounting of the suction nozzle 18. As an example and not a limitation, there may be multiple elastic arms, which may be spaced apart along the inner peripheral wall of the bracket 25.

[0175] In another alternative embodiment, such as Figures 4 to 6 As shown, the support 25 includes a support body 256 and a plurality of first elastic grippers 232 extending along the length of the support body 256. The first elastic grippers 232 can deform under external force and generate an elastic force in the direction of the longitudinal axis of the support 25. When the suction nozzle 18 passes through the receiving space formed by the plurality of first elastic grippers 232 along the longitudinal axis of the support 25, the first elastic grippers 232 are squeezed by the suction nozzle 18 and generate an elastic force in the direction of the longitudinal axis of the support 25, thereby clamping the suction nozzle 18 located at the longitudinal axis of the support 25.

[0176] Unlike the magnetic attraction method and elastic gripper mentioned above, such as Figures 10 to 14 As shown, in another optional embodiment of this application, the first connection structure 23 includes a connecting pin 233. The connecting pin 233 is configured to be inserted from the air outlet 182 of the nozzle 18 into the air outlet channel 181 of the nozzle 18.

[0177] Considering that condensate in the aerosol supply system 10 may flow out from the outlet 182, in a further embodiment of this application, the connecting pin 233 is configured to seal the outlet channel 181 when inserted into it, so as to avoid or reduce the outflow of condensate. In this embodiment, the connecting pin 233 simultaneously seals the outlet channel and connects the nozzle 18 to the cover 20, simplifying the structure of the cover 20.

[0178] As an example and not a limitation, the connecting pin 233 may have a flexible outer peripheral wall, and the flexible outer peripheral wall may be used to connect with the air outlet 182 through an interference fit. Alternatively, the connecting pin may be made entirely of soft rubber to achieve an interference fit.

[0179] As another example, and not a limitation, the connecting pin 233 has a raised edge that, when inserted into the nozzle, seals the outside of the nozzle's outlet 182, thus preventing condensate from flowing out and effectively sealing the nozzle 18. Furthermore, the connecting pin can be made of a hard plastic material.

[0180] It should be noted that, in this embodiment of the application, the cover 20 may include a sealing pin configured to seal the vent passage 181 when inserted, so as to avoid or reduce the outflow of condensate. However, the sealing pin may not be used as a connecting structure.

[0181] Referring to the preceding description of the first connecting structure 23, the connecting pin 233 can be disposed at any possible location on the cover 20, or on any possible component of the cover 20, as needed. In one embodiment, such as Figure 10 , Figure 11 As shown, the connecting pin 233 is located on the inner wall of the end of the cover body 24 away from the opening 22, and the connection between the cover body 24 and the nozzle 18 is achieved through the connecting pin 233.

[0182] In another way, such as Figures 12 to 14 As shown, the connecting pin 233 is located at the end of the bracket 25 away from the opening 22, and the bracket 25 can be connected to the nozzle 18 through the connecting pin 233. To finally connect the cover body 24 to the nozzle, as shown... Figures 12 to 14 As shown, the connecting pin 233 is also provided with an insertion groove 2331, and the cover body 24 has a pin 242 that matches the insertion groove 2331. In this way, the bracket 25 is connected to the cover body 24 through the cooperation of the insertion groove and the pin, and thus the cover body 24 is connected to the nozzle 18.

[0183] To further understand the working relationship between the cover 20 and the aerosol supply system 10, Figure 14 It shows the basis Figure 12 , Figure 13 The cover structure shown is connected to the aerosol supply system 10.

[0184] The embodiments described above can be applied individually to the cover 20, or they can be combined with each other in the cover 20. For example, the first connecting structure 23 can simultaneously have the following features: Figure 13 The diagram shows two connection methods: connecting pins and magnetic attraction. For example, the first connection structure 23 and the second connection structure can respectively... Figure 13 The connecting pins and magnetic attraction methods are shown.

[0185] Figure 18 The structure of a retractable cap is shown. The cap 30 includes a cap body 31 and a moving part 32. The cap body 31 has a covered position and an uncovered position. The moving part 32 can move relative to the cap body 31 in a preset manner. When it extends to the covered position, it covers the air outlet 182; when it retracts to the uncovered position, it opens the air outlet 182. Unlike insert-type caps, the retractable cap 30 does not require moving the entire cap 30 relative to the nozzle; simply moving the moving part relative to the cap body is sufficient to cover or open the air outlet 182.

[0186] The movable component 31 can be moved relative to the cover body by at least one of sliding or rotating.

[0187] The movable component may include one or more stops. When there are multiple stops, the air outlet can be covered or opened by the cooperation of the multiple stops. For example, the air outlet can be covered by multiple stops moving closer to each other, and the air outlet can be exposed by multiple movable components moving further apart. The stops can be set in any feasible shape, such as sheet-like, block-like, petal-like, spherical, etc., and this application does not impose any specific limitations on them.

[0188] The cover body can be configured in any feasible shape, such as plate-shaped, tubular, etc., and this application does not impose any specific limitations on it. The cover body can be provided with a fixed connection structure for fixed connection with the suction nozzle. This fixed connection structure can be a detachable connection structure or a non-detachable connection structure. Specifically, at least one of the following methods can be selected: welding, bolt connection, interference fit, snap-fit, magnetic attraction, etc. This fixed connection structure can also be configured with reference to the first connection structure mentioned above.

[0189] Figure 18 In the structure shown, the cover body 31 has a through hole 311, which is configured to communicate with the air outlet of the suction nozzle. The moving part 32 consists of two plate-shaped baffles 321. The two baffles 321 are configured to be slidably connected relative to the cover body 31. When the two baffles 321 slide toward each other until they contact each other, they cover the through hole 311, thereby covering the air outlet. When the two baffles 321 slide away from each other and separate, they open the through hole 311, thereby opening the air outlet.

[0190] In another alternative embodiment, it can be Figure 18 The movable component is replaced with a spherical stop with a through hole. The spherical stop is rotatably disposed in the through hole 311 of the cover body. When the spherical stop rotates to the point where the through hole is connected to the through hole, the air outlet is opened; when the spherical stop rotates to the point where the through hole is not connected to the through hole, the air outlet is covered.

[0191] In another alternative embodiment, the moving part can be a plurality of arc-shaped lobes, and the plurality of arc-shaped plates can be configured to close when rotated about their respective rotation axes to a blocking position to block the air outlet.

[0192] In a further embodiment, such as Figures 5 to 6 , Figures 8 to 13 as well as Figures 19 to 20 As shown, the cover 20 has a vent 27. The vent 27 is provided to provide airflow into the mouth when a human, especially an infant, accidentally swallows the mouthpiece, thus preventing suffocation. It also facilitates the drainage of cleaning wastewater from the vent when cleaning the cover cavity, thus avoiding or reducing the residue of wastewater in the cover cavity.

[0193] Taking Gai 20 as an example, such as Figures 5 to 6 , Figures 8 to 13As shown, the vent 27 can be provided on the end wall of the cover 20 away from the opening 22. In another alternative embodiment, as... Figure 19 , Figure 20 As shown, a vent hole 27 can be provided on the side wall of the cover 20 so that air can enter the cover 20 from the side wall.

[0194] In a further embodiment, ventilation holes 27 can be provided on both the end wall and the side wall of the cover 20 to increase the number of air intake positions on the cover 20.

[0195] This application may include a vent 27, or it may be as follows: Figure 19 , Figure 20 The diagram shows a plurality of vent holes 27. In a further embodiment, the plurality of vent holes 27 may be arranged circumferentially along the sidewall of the cover 20. The circumferentially spaced vent holes 27 allow air to enter the cover 20 from multiple circumferential locations.

[0196] In at least some embodiments of this application, the vent 27 can be configured as a circular hole, such as... Figure 19 As shown. In an alternative embodiment, the vent 27 can be a generally elongated strip-shaped vent. This strip-shaped vent may include, for example... Figure 20 The regular vertical strip-shaped holes shown may also include irregular strip-shaped holes with a tortuous extension pattern but whose overall trend extends along the height direction of the cover 20.

[0197] Understandably, the size of the vent 27 should be smaller than the size of the vent 182.

[0198] Example 2

[0199] Embodiment 2 of this application provides an aerosol supply system. The aerosol supply system includes a main body having a proximal end and a distal end opposite to the proximal end, wherein the proximal end is provided with a nozzle, the nozzle having an outlet channel for aerosol output and an outlet located at the proximal end of the outlet channel; the system also includes a cover, the cover being configured to cover or open the outlet.

[0200] In one alternative embodiment, the cap is detachably connected to the system body, and when the cap is configured to open the nozzle's air outlet, the cap is completely detached from the system body. Understandably, in this configuration, the cap, completely detached from the body, is prone to loss. Therefore, in a further embodiment, the cap, completely detached from the body when the nozzle's air outlet is opened, can be detachably reattached to the system body without affecting the opening of the air outlet. For example, it can be reattached to a remote end of the system to reduce the possibility of cap loss.

[0201] In one optional embodiment of this application, the force required to separate the cover from the body of the system is greater than the weight of the body of the aerosol supply system.

[0202] In one optional embodiment of this application, when the cap is magnetically attached to the bottom of the aerosol supply system, the adsorption force of the cap on the aerosol supply system is greater than the weight of the cap itself. Specifically, this adsorption force can be greater than 1.2 N.

[0203] In one optional embodiment of this application, the main body of the aerosol supply system includes a cartridge and an aerosol supply device. In one embodiment, the cartridge may include, for example: Figure 1 The liquid storage chamber 14 and atomizer 15 shown, the aerosol supply device may include, for example, Figure 1 The controller 16 and battery 17 are shown. The cartridge and aerosol supply device are detachably connected (e.g., by magnetic attraction). In this case, if the force required to separate the cap from the main body of the aerosol supply system is greater than the force required to separate the cartridge from the aerosol supply device, the cartridge may separate from the aerosol supply device during the cap separation process. Therefore, in a further embodiment of this application, the force required to separate the cap from the main body of the aerosol supply system is set to be less than the force required to separate the cartridge from the aerosol supply device. In one specific embodiment, the force required to separate the cap from the main body of the aerosol supply system is 0.5N to 2N.

[0204] In another alternative embodiment, the cover is configured to be connected to the main body via a connecting component when the air outlet of the suction nozzle is opened; that is, the relative position of the cover and the suction nozzle changes, but the cover does not detach from the main body. In this configuration, the cover remains connected to the main body of the system, making it less prone to loss. The cover can be entirely movable relative to the main body, for example, the cover could be two sliders movably connected within the main body via a slide rail. Alternatively, the cover can be partially movable relative to the main body, for example... Figure 18 In the structure shown, the cover body remains stationary, while only the moving parts are movable relative to the cover body, that is, relative to the main body.

[0205] In a further embodiment, the system also includes an operating terminal connected to the moving component and configured to be operated by a user to drive the moving component to move. The operating terminal can be a simple mechanical structure to drive the moving component mechanically, such as a sliding button or a pull cord. Alternatively, the operating terminal can be an electronically controlled component to drive the moving component to move via electrical signals. Specifically, the electronically controlled component can be a pressure sensor; the user pressing the pressure sensor generates an electrical signal, and the controller within the system drives the moving component to move based on this electrical signal.

[0206] The operating end can be located on the main body, such as a sliding button on the outer surface of the main body for pushing the slider. Of course, the operating end can also be located on the cover, or even on the moving part.

[0207] It should be noted that, regardless of the connection relationship between the cover and the main body, the corresponding connecting parts can be set on the cover, on the main body, or both the cover and the main body can be equipped with connecting parts to cooperate with each other.

[0209] The aerosol supply system in Embodiment 2 of this application may be the same as or similar to the aerosol supply system 10 in Embodiment 1. The identical features of the system will not be described again here.

[0210] Corresponding to the first connecting structure of the cap mentioned in Embodiment 1, the nozzle end of the aerosol supply system can be provided with a third connecting structure that cooperates with the first connecting structure. For example, when the first connecting structure is magnetic, the nozzle end of the system can be provided with a magnetic third connecting structure.

[0211] Corresponding to the second connecting structure of the cover mentioned in Embodiment 2, a fourth connecting structure that cooperates with the second connecting structure can be provided at the far end of the aerosol supply system.

[0212] Corresponding to the second connecting structure of the cover and the vent structure mentioned in Embodiment 1, the aerosol supply system is provided with an air inlet at the far end, and the vent can be set to allow normal air intake.
