Description

Technical Field

[0001] The present invention relates to an electronic device, and in particular to an electronic atomization device. Background Art

[0002] An electronic atomization device is an electronic device that operates by supplying power to an aerosol generator and heating the aerosol-generating material to generate an atomization effect. Common electronic atomization devices include electronic aerosol-generating devices containing nicotine. A button is usually provided on the surface of the device, and the aerosol generator (also known as a nebulizer) is activated by pressing the button. Another activation scheme is to have an airflow sensor in the electronic aerosol-generating device. When the user needs to use it, he or she can inhale slightly at the outlet of the aerosol. The airflow sensor senses the airflow and turns on the power to make the nebulizer work.

[0003] However, aerosol generating devices are generally designed to be compact, and when buttons are provided, the size of the buttons is also relatively small. This makes it difficult for users, who are usually males, to press the buttons because the buttons are too small for their fingers to feel.

[0004] For atomization devices that use airflow sensors, although the button for starting the atomizer is eliminated, as an electronic product, there is still a need for other electronic functions, such as display / indication functions, atomization volume adjustment, etc., so there is still a need to set buttons or other control methods.

[0005] Therefore, it is necessary to design a design solution that can replace buttons, provide a better user experience, and even better if it can integrate more functions under the conditions of small size and limited design space of electronic atomization devices. Summary of the Invention

[0006] The present invention protects an electronic atomization device, characterized by comprising:

[0007] an atomizing chamber having a cavity for accommodating an aerosol-generating material;

[0008] an aerosol generator for heating the aerosol-generating material to form an aerosol;

[0009] a power source for providing power for heating the aerosol generator;

[0012] The function implementation mechanism enables the electronic atomization device to switch from a first functional state to a second functional state when the outer shell moves from a first position to a second position relative to the inner shell.

[0013] Furthermore, the inner shell and the atomization chamber are an integrated structure.

[0014] Furthermore, the function implementation mechanism includes an airway, which is located on the inner shell for the aerosol to form and flow through. In the first position, the inlet and outlet of the airway are closed by the outer shell and blocked from the atmosphere, so that the electronic atomization device is in a first functional state in which the airway is closed; in the second position, the inlet and outlet of the airway are connected to the atmosphere, so that the electronic atomization device is in a second functional state in which the airway is open.

[0015] Furthermore, the outer shell is provided with an air inlet and / or an air outlet, and the inlet and / or outlet on the inner shell are offset from the air inlet and / or the air outlet and blocked from the atmosphere when the outer shell is located in the first position, and are aligned with the air inlet and / or the air outlet and connected to the atmosphere when the outer shell moves to the second position.

[0016] Furthermore, the outer shell only covers a partial area of the inner shell, and the inlet and / or outlet on the inner shell is located within the covering area of the outer shell and is blocked from the atmosphere when the outer shell is located in the first position, and moves out of the covering area of the outer shell and is connected to the atmosphere when the outer shell moves to the second position.

[0017] Furthermore, the outer shell includes a structural area for forming an air inlet and / or an air outlet, the structural area having an inner wall surface facing the inlet and / or outlet of the inner shell and having a connecting space therewith, and also having a lateral wall surface connecting the inner wall surface and the outer surface of the outer shell.

[0018] Furthermore, the outer shell is tubular, and the inner shell is located inside the tubular outer shell; at least one end of the outer shell is an inclined surface inclined relative to the axial direction, and the function implementation mechanism causes the outer shell to rotate around the axial direction, and the inlet and / or outlet of the airway on the inner shell is located in the space enclosed by the rotation trajectory of the inclined surface.

[0019] Furthermore, the inner shell is also provided with a slope, which is accommodated inside the outer shell when the outer shell is in the first position. When the outer shell reaches the second position with the cooperation of the function implementation mechanism, the slope moves to be coplanar with the slope of the outer shell.

[0020] Furthermore, the distance between the inner surface of the outer shell and the outer surface of the inner shell is less than 0.3 mm, or they are made of different materials.

[0021] Furthermore, at least one of the four is provided with a seal between the air inlet of the outer shell and the inlet of the inner shell, between the air outlet of the outer shell and the outlet of the inner shell, between one end surface of the covering area of the outer shell and the inlet of the inner shell, and between the other end surface of the covering area of the outer shell and the outlet of the inner shell.

[0022] Further, the outer shell includes a first part and a second part, and the first part moves from the first position to the second position relative to the second part or relative to the inner shell;

[0023] In the first position, the first portion and the second portion are axially assembled to form a closed curved surface as a whole or together with a portion of the surface of the inner shell to form a closed curved surface, thereby isolating the air passage of the inner shell from the atmosphere;

[0024] In the second position, the first portion is axially separated relative to the second portion or relative to the inner casing, thereby forming a separation area to allow atmospheric air to enter from the outer casing and communicate with the air passage of the inner casing.

[0025] Furthermore, the first part rotates axially or moves linearly along the axial direction relative to the second part or the inner shell.

[0026] Furthermore, there is a distance between the inner surface of the outer shell and the outer surface of the inner shell, and the distance is greater than 0.3 mm.

[0027] Furthermore, the function realization mechanism also includes a transmission mechanism for guiding the outer shell to move from the first position to the second position, and the transmission mechanism is a slide groove, a key, a gear, a cam or a connecting rod mechanism.

[0028] Furthermore, the function implementation mechanism includes a switch connected to the aerosol generator, and when the outer shell is in the first position, the switch is powered off, and the electronic atomization device is in a first functional state in which the circuit is disconnected; when the outer shell reaches the second position, the switch is powered on, and the electronic atomization device is in a second functional state in which the circuit is connected.

[0029] Furthermore, the switch is a touch switch, an electromagnetic switch, a photoelectric switch, a delay switch or a proximity induction switch.

[0030] Furthermore, a first contact and a second contact are provided on the inner shell or the outer shell. When the outer shell is located at the first position relative to the inner shell, the switch contacts or passes through the first contact to de-energize the switch; when the outer shell is located at the second position relative to the inner shell, the switch contacts or passes through the second contact to energize the switch.

[0031] Furthermore, the switch is located on the inner housing, and the first contact and the second contact are located on the outer housing; or the switch is located on the outer housing, and the first contact and the second contact are located on the inner housing; the first and second contacts are located on a relative movement trajectory of the switch as the outer housing moves relative to the inner housing.

[0032] Further, when the outer shell is located between the first position and the second position relative to the inner shell, the electronic atomization device is in the first functional state.

[0033] Furthermore, the function implementation mechanism enables the relative movement of the outer shell to move from a position between the first position and the second position to the second position, and the electronic atomization device still maintains the first functional state.

[0034] Furthermore, the function implementation mechanism also includes a position detection component, which detects and determines the starting position of the relative movement of the outer shell.

[0035] Furthermore, the function implementation mechanism further includes a time detection element, which detects and determines the time interval between the time point when the outer shell moves relatively to the second position this time and the time point when it last moved to the second position.

[0036] Furthermore, the function implementation mechanism enables the electronic atomization device to maintain the first functional state when the time interval between the time point when the outer shell moves relative to the second position and the time point when it last moved to the second position is less than a preset time interval.

[0037] Furthermore, the function implementation mechanism includes a reset component, and the reset component enables the outer shell to automatically reset to the first position when the outer shell moves away from the second position relative to the inner shell.

[0038] Furthermore, the function implementation mechanism includes a display element that indicates the working status of the electronic atomization device. When the outer shell is in the first position relative to the inner shell, the effective display area of the display element is shielded, and the electronic atomization device is in a first functional state that does not display the working status; when the outer shell is in the second position relative to the inner shell, the effective display area of the display element is exposed, and the electronic atomization device is in a second functional state that displays the working status.

[0039] Furthermore, the display element is a marking area having a boundary. When the outer shell moves to the second position relative to the inner shell, the boundary of the marking area is revealed, indicating that the relative movement is completed.

[0040] Furthermore, the display element is a display screen element, which obtains parameters related to the working state of the electronic atomization device through electrical elements and displays them on the screen.

[0042] Furthermore, the outer shell includes a first part and a second part, and the first part moves axially apart relative to the second part or the inner shell; in the first position, the first part and the second part of the outer shell are spliced together; in the second position, the first part and the second part of the outer shell are separated to produce a separation area, and one end of the first part leaves the inner shell to produce a drop area.

[0043] Furthermore, the light of the lighting element is guided to the separation area or the drop area, so that the light is shielded in the first position and is displayed in the separation area or the drop area in the second position.

[0044] The beneficial effects of the present invention are as follows: the present invention enables the electronic atomization device to switch from a first functional state to a second functional state by moving the outer shell covering the inner shell relative to the inner shell, so that it moves from a first position to a second position, thereby achieving functional switching; the movement of the outer shell of the present invention can be achieved by the user with one hand, and the surface area of the outer shell is relatively large, which is more convenient for the user to operate. In addition, the movement of the shell not only causes changes in the mechanical structure, but also drives the switching of electrical functions, thereby easily achieving the simultaneous realization of multiple functions and being more conducive to further miniaturization.

[0053] The present invention relates to an electronic atomization device, such as Figure 1 As shown, it at least includes an atomizing chamber 40, an aerosol generator and a power supply 30 to realize the function of electronic atomization. The atomizing chamber 40 has a cavity for accommodating an aerosol generating material. The aerosol generating material can be any liquid that can be atomized, such as water, milk, essential oil, toner or moisturizing lotion for skin moisturizing, or therapeutic drugs, such as ambroxol and chymotrypsin for treating children's cough, or nicotine-containing oil for relieving smoking addiction or replacing smoking, etc., which are not limited in this article. The aerosol generating material can also be a solid, which has one or more components that can be heated and evaporated and atomized, such as a tobacco paste (a material with nicotine in the form of a paste), or tobacco leaves, tobacco powder or tobacco particles, etc., or other solid materials that can be heated to form smoke or aerosols, which are not limited in this article.

[0054] The aerosol generator operates under the power supply of power source 30 to heat the aerosol-generating material, causing it to evaporate and vaporize, thereby forming an aerosol. The heating and evaporation principles of an aerosol generator can be implemented in various ways, such as resistance heating, electromagnetic induction heating, microwave heating, light heating, phase change reaction heating, or chemical reaction heating.

[0055] Resistive heating utilizes the thermal effect of current passing through a resistor to electrically heat a material. For example, an aerosol generator consists of a resistor wire with a specific resistance value and a liquid-conducting core. The liquid-conducting core guides the aerosol-generating material to the resistor wire. When powered, the resistor wire generates heat, heating the aerosol-generating material until it evaporates. The liquid-conducting core can also be omitted, and the resistor can be directly inserted into the aerosol-generating material for heating, especially when the aerosol-generating material is solid.

[0056] The resistance wire is a spiral coil, or a serpentine structure, or other shapes and structures such as a mesh, strip, rod, sheet, etc. The material of the resistance wire can be at least one of metal materials such as iron-chromium-aluminum alloy, nickel-chromium alloy or stainless steel.

[0057] The liquid-conducting core contacts or even immerses in the aerosol-generating material, and has one end or surface close to the resistance wire, thereby guiding the aerosol-generating material to the resistance wire. Here, "guiding to" can mean that the aerosol-generating material is directly in contact with the resistance wire, or it can be close to the resistance wire with a distance therebetween. The liquid-conducting core can be a fiber bundle, such as a cotton bundle or a glass fiber bundle. The liquid-conducting core can also be other columnar or block structures, such as oil-conducting cotton, porous ceramic rings or ceramic blocks. The liquid-conducting core can be located on the outer surface of the resistance wire, such as above, below, left and right, or it can be located on the inside of the resistance wire in whole or in part. For example, a liquid-conducting core made of a cotton bundle has a resistance wire with a spiral coil structure on one end or a mesh resistance wire on one end, and the other end is immersed in the aerosol-generating material; or a liquid-conducting core with a ceramic ring structure has a spiral coil on the inner side wall or the outer ring wall, etc. This article does not limit this.

[0058] Electromagnetic induction heating uses electromagnetic induction to generate electric currents within the heated material, relying on the energy of these eddy currents to achieve heating. Aerosol generators based on this principle generally consist of an induction unit and a magnetic field generator. The magnetic field generator, when powered in a specific manner, generates an alternating magnetic field, which creates eddy currents within the induction unit within the magnetic field, generating heat. This heat then heats the aerosol-generating material. The induction unit can be comprised of multiple discrete small components dispersed throughout the aerosol-generating material, or it can be constructed as an induction coil, nestled within the aerosol-generating material, or placed near the aerosol-generating material or atomizing chamber.

[0059] Microwave heating and light heating are two other possible heating methods. One method uses the energy characteristics of microwaves to heat objects, and the other method uses a light source with a high energy density, such as an LED or LD, to irradiate the liquid to heat it. Other possible heating methods include phase change reaction heating and chemical reaction heating. Phase change reaction heating uses phase change materials to convert between solid, liquid, and gas states to store or release heat. Chemical reaction heating relies on the heat released by chemical reactions to heat aerosol-generating materials. Patents have been described in the prior art, and the details will not be repeated here.

[0060] Regardless of which of the above heating methods or other heating methods is used, as long as the aerosol generator heats the aerosol generating material, causing the aerosol generating material to increase in temperature and vaporize and evaporate, that is, the aerosol generating material changes from liquid phase to gas phase, such heating method falls within the scope of heating evaporation of the present invention.

[0061] The electronic atomization device of the present invention also includes an inner shell 20, an outer shell 10 and a function implementation mechanism. The inner shell 20 accommodates the aforementioned atomization chamber 40 and the aerosol generator, wherein the aerosol generator may be located in the atomization chamber 40 in whole or in part. The atomization chamber 40 may be located in the inner shell 20 having an inner cavity, or the cavity wall of the atomization chamber 40 may constitute a part of the wall of the inner shell 20. For example, the bottom of the atomization chamber 40 is connected to the power supply shell or power supply fixing frame equipped with the power supply 30, then the cavity wall of the atomization chamber 40 and the surface layer of the power supply shell or power supply fixing frame together constitute the inner shell 20. The outer shell 10 is arranged on the periphery of the inner shell 20 and at least partially covers the surface of the inner shell 20. Or the outer wall of the cavity of the atomization chamber 40 extends directly to the inner cavity accommodating the power supply, that is, the inner shell 20 is an integrated structure with the atomization chamber 40.

[0062] In the present invention, the outer shell 10 can move relative to the inner shell 20, so that the relative position of the outer shell 10 moves from a first position to a second position. Specifically, the outer shell 10 can move while the inner shell 20 is stationary, or the inner shell 20 can move while the outer shell 10 is stationary, or both can move but not synchronously, resulting in relative displacement. For the sake of convenience of description, the present invention is described as the inner shell 20 being in a relatively stationary state, but it does not mean that the inner shell 20 is absolutely stationary. The mode of movement can be that the outer shell 10 as a whole or in part moves relative to the inner shell 10 along a specific motion trajectory on the inner shell 20 or on the rest of the electronic atomization device. The displacement motion has a specific starting point, end point and motion trajectory, and the displacement does not cause the outer shell 10 to separate from the overall structure of the electronic atomization device itself. This makes the outer shell 10 of the present invention essentially different from the detachable or flip-up box cover of traditional electronic products.

[0063] In addition, the outer shell 10 of this article should be distinguished from the button, because the outer shell 10 here is a ring surface or a near-ring surface structure that covers the inner shell 20, so it can be in a covering state; in addition, the outer shell 10 of this article serves as the appearance structure of the entire electronic atomization device, and its covering area should be significantly larger than the inner shell 20, for example, the surface area of the inner shell covered is more than 50%, or it constitutes the main appearance feature of this device.

[0064] The inventive point of the present invention is that the present invention also includes a function implementation mechanism, which moves the outer shell 10 from a first position to a second position relative to the inner shell 20, so that the function of the electronic atomization device related to the function implementation mechanism is switched from a first functional state to a second functional state.

[0065] For example, the function realization mechanism of the electronic atomization device includes an airway for air to enter to cool the evaporated aerosol-generating material, which is cooled and forms an aerosol before escaping. The electronic atomization device of the present invention switches the airway from a first functional state of being closed and isolated from the atmosphere to a second functional state of being open and connected to the atmosphere after the outer shell 10 moves relative to the inner shell 20.

[0066] Alternatively, the function realization mechanism of the electronic atomization device of the present invention includes a switch, which connects the aerosol generator and the power supply 30. When the outer shell 10 of the device is in a first position, the switch is disconnected, so that the electronic atomization device is in a first functional state in which the circuit is disconnected; when the outer shell 10 is in a second position relative to the inner shell, the switch is connected, so that the electronic atomization device is in a second functional state in which the circuit is connected;

[0067] Alternatively, the function implementation mechanism of the electronic atomization device includes an indicator light, the lighting, flashing or light color change of the indicator light can indicate the operating status of the device to the user. When the outer shell of the device is in the first position 10, the indicator light is turned off or its light is blocked, and the device is in a first functional state without operating status indication; and when the outer shell 10 moves relatively to the second position, the indicator light is turned on or revealed, and the device is in a second functional state of indicating the operating status; similarly, the function implementation mechanism can also be a display screen, which is blocked or turned off in the first position and turned on and displays relevant information in the second position.

[0068] Therefore, this electronic atomization device, which is usually an electronic device that can be operated with one hand, can easily move the outer shell from a first position to a second position relative to the inner shell through manual operation, such as twisting, pushing, pulling and other actions, thereby increasing the playability of the device; and while operating, certain function switching can also be achieved, and the switching of this function can further increase the necessity of play and at the same time reduce the operating steps.

[0069] Below, the electronic atomization device of the present invention will be described through specific embodiments and drawings, in which similar elements in different embodiments use associated similar element numbers. It should be noted that the common and common technical features of each embodiment and the embodiments not listed have been fully described above. In the absence of clear contrary instructions or contradictions, all the above contents can be applied to the following specific embodiments, and it cannot be considered that the above technical features and contents can only exist independently of the embodiments. Moreover, in the following embodiments, many detailed descriptions are intended to enable this application to be better understood. However, those skilled in the art can easily realize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods, and cannot be regarded as necessary limitations on this embodiment.

[0070] Example 1:

[0071] Figures 2a to 2c The figure shows the structure of the electronic atomization device of the first embodiment of the present invention. Figures 2a to 2c As shown, the electronic atomization device includes a housing, an atomization chamber 40, an aerosol generator, and a power supply 30. The atomization chamber 40 contains an aerosol-generating material, which is a liquid containing nicotine or other medications to be atomized. When connected to the power supply 30, the aerosol generator heats the aerosol-generating material, vaporizing it and mixing it with air to form an aerosol. After escaping from the housing, the aerosol can be inhaled through the user's mouth or nose, where it can be absorbed by the body and have certain effects on the airway, such as relieving smoking cravings, treating asthma or epilepsy, or relieving coughs.

[0072] Wherein the housing comprises an inner housing 20 and an outer housing 10. In this embodiment, the aerosol generator is located inside the atomizing chamber 40 and is not shown. The atomizing chamber 40 and the power supply 30 are located inside the inner housing 20 or the outer wall is an integral structure with the inner housing and is not shown. An airway is provided on the atomizing chamber 40, which is the function implementation mechanism in this embodiment. The airway is located on the inner housing 20 and passes through the atomizing chamber 40, and at least includes an inlet and an outlet and an air flow channel between the inlet and the outlet. Of course, the outlet, inlet and air flow channel here do not necessarily have a specific structure. As long as there is a position or area on the atomizing chamber that allows air to enter and contact the aerosol-generating material, and air can flow and escape therein, for example, only by the presence and penetration of air itself and flowing inside and outside the atomizing chamber, it is also considered that the atomizing chamber has the airway described in the present invention, and the airway has an inlet and an outlet. When the atomizing chamber 40 is located in the inner housing 20, there is an inlet and an outlet on the corresponding inner housing that allow air to enter and escape the atomizing chamber. This article does not limit its position and form.

[0073] like Figure 2aAs shown, in this embodiment, the inner housing 20 is cylindrical, and the outer housing 10 is also similarly cylindrical, including a cylindrical side surface 17 and end portions 16 at both ends, which entirely cover the inner housing 20. The outer housing 10 includes a first portion 12 and a second portion 14, which are joined together along the axial direction L of the housing. The joining surface 13 is a plane or curved surface that forms a certain angle with the axial direction L. The angle here is between 0 and 90 degrees, that is, the joining surface 13 is inclined relative to the axial direction L. At this time, the outer housing 10, especially the first portion 12 of the outer housing 10, is located in a first position relative to the inner housing 20.

[0074] In addition, a spacing is provided between the inner wall of the outer shell 10 and the outer wall of the inner shell 20, and the spacing is at least greater than 0.3 mm, so that air can flow in the spacing space, and the gas is connected to the airway on the inner shell 20. A vent 11 is provided at the end of the first part 12. When the first part 12 is in the first position, the vent 11 is blocked by a raised structure 22 provided at the corresponding end of the inner shell 20. At the same time, the first part 12 and the second part 14 are spliced together, so that the entire outer shell 10 cooperates with the end of the inner shell 20 to form a closed shell, blocking the atmosphere outside the outer shell 10 from the atmosphere inside it, and the airway cannot be connected to the external atmosphere. Therefore, when the first part 12 is in the first position, the electronic atomization device is in the first functional state of airway closure.

[0075] Since the inner shell 20 and the outer shell 10 are cylindrical, and the joint surface 13 is inclined, the joint surface 13 is approximately an inclined elliptical surface. Figure 2b 、 Figure 2c As shown, the second part 14 and the inner shell 20 are fixed together in a relatively static manner, and the first part 12 can move relative to the second part 14, that is, relative to the inner shell 20. In this embodiment, the rotation around the axis and the axial displacement ultimately produce a spiral motion. The spiral shape here is not necessarily a spiral shape in the strict geometric sense, that is, a situation where a circular motion also has a uniform linear motion. In the present invention, as long as a component has an axial displacement while rotating, it can be understood as a spiral shape. After the first part 12 rotates to a predetermined second position, a separation area is formed between the joint surface 18 of the first part 12 and the joint surface 19 of the second part 14. This area constitutes an air inlet 21, which is connected to the air inside the outer shell 10 to form an air inlet channel.

[0076] At the same time, because the first portion 12 is axially displaced relative to the second portion 14, the vent 11 at the end of the first portion 12 is no longer blocked due to its upward movement away from the end of the inner housing 20, becoming an air outlet 15. This allows the atmosphere outside the outer housing 10 to communicate with the atmosphere inside the outer housing 10 through the air outlet 15, forming an air outlet passage. At this point, the first portion 12 moves to the second position, and the electronic atomizer device is in its second functional state, with the airway open.

[0077] Therefore, in this embodiment, when the first portion 12 is in the first position relative to the inner housing 20, the outer housing is a closed space, and the inlet and outlet of the internal atomizing air passage are both closed. When the outer housing 10 is moved to the second position through relative displacement, an air inlet 21 and an air outlet 15 are formed on the outer housing 10, and are connected to the inlet and outlet of the internal air passage through the gap between the inner housing 20 and the outer housing 10, that is, the air passage is open. Obviously, the positions of the air inlet 21 and the air outlet 15 are interchangeable.

[0078] The inlet and outlet of the airway are closed before the action, and are not opened until the user performs a hand action when using it. This can bring very great beneficial effects in practical applications. Because the airway is an indispensable structure for the atomization device that evaporates by heating, the airway is introduced through the airway to quickly cool the steam downstream of the aerosol generator, so that it condenses the nominal aerosol. However, whether it is liquid or gas, as long as there is a physical gap, it is likely to cause problems such as liquid leakage and air leakage. The user's inhalation experience of liquid or droplets is very bad, which should be avoided as much as possible; in addition, during the transportation of the equipment, due to the existence of the airway, when the air pressure in the atomization chamber connected to the airway is inconsistent with the ambient air pressure, such as during air transportation, it is easy to cause leakage, affecting the use of the product. In the present invention, the airway is completely closed and isolated from the atmosphere before use, which completely avoids the occurrence of these situations.

[0079] Therefore, the present invention protects such an electronic atomization device, which forms an enclosed space when the first part 12 of the outer shell 10 is in the first position, or cooperates with a partial area of the inner shell 20 to form a enclosed space, and forms an air inlet 21 and an air outlet 15 in the second position so that the internal air duct is connected to the atmosphere.

[0080] In this embodiment, the functional implementation mechanism includes, in addition to the airway, a transmission mechanism that guides the first portion 12 from the first position to the second position. The transmission mechanism's positional constraints ensure that the first portion 12 always moves along the mating surface 19 of the second portion 14. This means that at least one point on the first portion 12 maintains contact with the mating surface 19 of the second portion 14, thereby maintaining a compact structure and a comfortable feel for the user. This transmission mechanism can be implemented through various structural designs, such as spring pressure, slideway and rail positional constraints, key engagement, gears, pulleys, or linkages, though these are not limited herein.

[0081] Furthermore, in this embodiment, the joint surface 13 can be a plane, that is, the joint surface 13 has a projection plane such that its projection on the projection plane is a straight line. In this case, the movement of the first portion 12 relative to the inner housing 20 is a standard spiral. When the projection of a joint surface 13 on the projection plane is a curve, such a joint surface is actually a curved surface. Preferably, the joint surface is a curved surface with a symmetric plane, in which case the symmetric plane can be the projection plane of the joint surface. In this case, the relative movement is a spiral in a broad sense.

[0082] In the cylindrical shell structure of this embodiment, the projection of the joint surface 13 onto the symmetry plane is preferably a curve, and the curve is rotationally symmetrical. The inclination angle of the end curves of the curve relative to the axial direction is greater or less than the inclination angle of the middle curve relative to the axial direction, that is, the degree of inclination of the two ends of the curve relative to the middle portion is different. This structure reduces the axial displacement of the first part 12 when it is separated along the axial direction, that is, the user does not need to make large movements during operation, which is conducive to miniaturization and convenient operation. When the user holds the second part, pinching the first part with the thumb and index finger, applying force to rotate it, the fingers will not be pushed too far upward, resulting in an unnatural feel, and the user experience is good. For similar reasons, the inclination angle of the joint surface relative to the axial direction is preferably greater than 45 degrees and less than 90 degrees, for example 60 degrees. In addition, the variation of the curves at the two ends is also conducive to designing the contour shape of the separation area enclosed after displacement.

[0083] The movement of the first portion 12 from the first position to the second position can not only switch the airway opening and closing functions, but also switch other functional states. For example, the movement of the first portion 12 relative to the inner housing 20 can be used to determine the action of starting the electronic atomization device.

[0084] Specifically, in another embodiment of the present invention, the electronic atomization device has a structure as in the above embodiment, such as the first part 12 and the second part 14, the inner shell 20, the aerosol generator and the atomization chamber 40, etc. The structural features of the above embodiment can all be cited in this embodiment and will not be repeated below.

[0085] Unlike the previous embodiment, the function-enabling mechanism in this embodiment is a switch, located between the power source 30 and the aerosol generator. When the first portion 12 is in the first position relative to the second portion 14, the switch is off, and the aerosol generator is in a first functional state with a disconnected circuit and unable to operate. When the first portion 12 moves to the second position, the switch is on, causing the aerosol generator to begin operating or enter a second functional state in which it is ready for operation.

[0086] There are many types of switches that can achieve this functional state switching, such as touch switches, electromagnetic switches, photoelectric switches, delay switches, proximity induction switches, etc. The above-mentioned switch switching function can be achieved by designing a corresponding transmission mechanism in combination with the type of switch. For example, in one embodiment, a touch switch is used, and a contact is provided on the inner shell 20 or the outer shell 10. In the first position, the switch does not contact the contact and the switch is disconnected; in the second position, the switch moves to connect with the contact, so that the switch is connected and the aerosol generator starts working. Alternatively, in another embodiment, a photoelectric switch is used. In the first position, the first part 12 blocks the photoelectric switch, resulting in the inability to receive light, and the photoelectric switch is disconnected. In the second position, the first part 12 no longer blocks the photoelectric switch, and the photoelectric switch is connected, and the aerosol generator starts working or enters the standby state, etc. This article will not go into details.

[0087] Of course, it should be noted that in this embodiment, the airway does not need to be switched between open and closed functional states. Therefore, the end of the first portion in this embodiment does not necessarily require a vent 11. Furthermore, when the first portion 12 is in the first position, it does not necessarily form an enclosed space with the second portion 14, or in other words, the first portion 12 does not necessarily need to be seamlessly connected to the second portion 14. Similarly, when the first portion 12 moves to the second position, it does not necessarily create a separate area from the second portion 14. Instead, it can move to a structure that still seamlessly connects with the second portion 14, or partially overlaps and nests with the second portion 14, or other structures.

[0088] Of course, in adopting Figures 2a to 2c When the outer shell structure is shown, the function switching of opening and closing the airway and whether the aerosol generator is working can be realized simultaneously. It is not only simple in structure, but also can significantly reduce the user's operation steps. At the same time, it also avoids the leakage problem caused by the airway being always open, and has a very good user experience and practical effect.

[0089] Therefore, the present invention also protects such an electronic atomization device, when the outer shell 10 is in a first position relative to the inner shell 20, the outer shell 10 as a whole or cooperates with the inner shell 20 to form a closed space so that the air inside the electronic atomization device is isolated from the atmosphere outside the outer shell 10, and the aerosol generator is powered off at this time; when the outer shell 10 moves to a second position relative to the inner shell 20, an air inlet channel and an air outlet channel are formed on the outer shell 10 or between the outer shell 10 and the inner shell 20, which are connected to the airway atmosphere on the inner shell 20, and at this time the aerosol generator starts working or enters a standby state.

[0090] On the other hand, in order to avoid misoperation, when the outer shell 10 of the electronic atomization device of the present invention moves from the first position to the second position, the device switches from the first functional state in which the aerosol generator is powered off to the second functional state in which it is powered on; when the outer shell 10 moves from the second position to the first position, the aerosol generator will switch to the first functional state in which the power is off, that is, when the outer shell 10 is located between the first position and the second position relative to the inner shell 20 and when it is in the first position, the device is in the first functional state in which the power is off. The function implementation mechanism of this embodiment, that is, the switch, has the following function, namely: when the relative movement of the outer shell 10 is from the position between the first position and the second position to the second position, the electronic atomization device still maintains the first functional state in which the power is off. That is, the electronic atomization device will switch from the first functional state to the second functional state only when the movement of the outer shell is from the first position to the second position.

[0091] The advantage of this design is that the user does not push the outer shell back to the first position after use, and may accidentally close it due to some circumstances. At this time, although the outer shell leaves the second position and the device switches to the power-off and non-working state, it remains to be determined whether the user has a clear need to restart the device. In order to avoid waste of aerosol-generated materials and equipment damage under abnormal use, it is very necessary to force the user to push the outer shell back to the first position to confirm the necessity of use.

[0092] There are many ways to implement the above functions. For example, the function implementation mechanism of this embodiment includes a switch, a first contact, and a second contact. The switch is located on the inner housing, and the two contacts are located on the outer housing 10, or vice versa. The first contact and the second contact are located on a relative movement trajectory of the switch as the outer housing 10 moves relative to the inner housing 20.

[0093] When the housing 10, for example, the first portion 12, is in the first position, it contacts or approaches the first contact, de-energizing the circuit. Then, as the housing 10 moves toward the second position, it passes the first contact and then passes or contacts the second contact, reaching the second position. At this point, the circuit energizes, and the aerosol generator is in operation or standby mode. When the housing 10 returns from the second position to the first position, whether it passes or contacts the first contact again can be determined to indicate whether it has returned to the first position. If the housing 10 does not return to the first position and moves directly from the intermediate position to the second position, the device can determine that the starting position is not the first position, thereby maintaining the first functional state rather than switching to the second functional state.

[0094] The first position and the second position can be determined by the difference between the first contact and the second contact. The distinction between the first contact and the second contact can be achieved by outputting different electrical signals each time the two contacts pass or touch each other, or by using a NAND gate algorithm, or by using a third switch that is triggered only when the two contacts work together. Corresponding technical solutions can be found in the existing technology and will not be described in detail herein.

[0095] For example, a feasible embodiment is that the electronic atomization device of the present invention also includes a microprocessor, which is connected to the switch. The switch sends a first electrical signal through a first contact and sends a second electrical signal through a second contact. The microprocessor receives the first and second electrical signals and stores and judges them. When the first electrical signal is received, the microprocessor controls the switch to be disconnected, and the device is in the first functional state; when the second electrical signal is received, the microprocessor determines that the electrical signal received before the electrical signal is the second electrical signal, and the device still maintains the first functional state. Such a design can encourage the user to fully move the device back to the first position each time to trigger the first electrical signal. Further optionally, when the second electrical signal is received, and it is detected that the electrical signal received before the electrical signal is the first electrical signal, and the time interval between the receipt of the first electrical signal and the second electrical signal is within a preset time, the device enters the second functional state. If the preset time is exceeded, the first functional state is still maintained.

[0096] In addition, whether the outer shell 10 moves to the second position from the first position rather than a position between the first position and the second position is not necessarily determined by determining whether it is in the first or second position. It can also be determined by using a position detection component to directly detect the current specific position. For example, light sensing, infrared, scanning, etc. can all be used to detect and determine the current position of the outer shell, and then further determine the relationship with the first and second positions.

[0097] On the other hand, in order to prevent excessive aerosol-generating materials from being atomized each time, especially when the aerosol-generating materials are nicotine or drug ingredients that need to be strictly controlled, the function implementation mechanism of the electronic atomization device of the present invention also includes a time detection element. The time detection element starts timing after the outer shell moves to the second position so that the device starts atomization, and after the atomization time reaches a preset value, the device stops atomization, that is, returns to the first functional state. For example, in an electronic atomization device containing nicotine, 10 seconds after the outer shell moves to the second position and the device enters the second functional state, the device will automatically return to the first functional state. At this time, the device can stop atomizing and can further control the outer shell to automatically reset to the first position.

[0098] Furthermore, the time detection element of the present invention can be used for other time detections, for example, it detects the time interval between the time point when the outer shell moves relative to the second position this time and the time point when it last moved to the second position. If the time interval is greater than the preset value, the device switches to the second functional state when it moves to the second position this time, otherwise, it still maintains the first functional state. This is because for nicotine or medicinal aerosol generating materials or other aerosol generating materials for entering the human body, the amount that can be absorbed in the human body has an upper limit, and a certain metabolic digestion time is required after each inhalation. Therefore, continuous and uninterrupted use, especially continuous use in a short period of time, should be avoided as much as possible. Setting a time interval is helpful in solving this problem. For example, for electronic atomization devices such as electronic cigarettes, the preferred time interval is more than 10 seconds.

[0099] Furthermore, the time detection element of the present invention can also be used to calculate the cumulative operating time. Specifically, the movement of the outer shell from the first position to the second position and then back to the first position is considered a cycle, and the cumulative time of each cycle is calculated. The specific calculation point can be the time between the starting point and the end point of the cycle as the effective time of a cycle, or the time spent at the second position as the effective time, or the time the device is in the second operating state during the time it stays at the second position as the effective time. When the time detection element detects that the cumulative time is less than a preset value, the outer shell moves from the first position to the second position, and the device switches to the second functional state. Conversely, even if the outer shell moves to the second position, the device maintains the first functional state.

[0100] The advantage of this design is that the amount of aerosol generating material is fixed. Usually, after a certain amount of aerosol generating material evaporates, the content of the effective ingredient decreases or the overall remaining content is too low, which may cause the atomized aerosol or aerosol to fail to achieve the expected effect, and may even cause negative effects due to reasons such as dry burning. Therefore, the above solution can remind users to replace the atomization chamber or update / add aerosol generating material as early as possible.

[0101] The function-enabling mechanism of the present invention may further include a reset assembly that drives the outer shell back to the first position when the outer shell moves from the second position to the first position, or when the electronic atomization device is in the first functional state but the outer shell is not in the first position relative to the inner shell. The reset assembly can be implemented by elastic element abutment, electromagnetic attraction, or other methods, which will not be described in detail herein.

[0102] It should be noted that, in the above embodiment, the first functional state is that the electronic atomization device circuit is disconnected and the aerosol generator is not working, and the second functional state is that the electronic atomization device circuit is connected and the aerosol generator is working to heat and atomize; it can also be that the first functional state is that the electronic atomization device circuit is powered on, but the aerosol generator is not working, that is, the standby state, and the second functional state is that the electronic atomization device circuit is connected, and the aerosol generator is heating and atomizing; or it can also be that the first functional state is that the electronic atomization device circuit is disconnected and the aerosol generator cannot work, and the second functional state is that the electronic atomization device circuit is powered on, but the aerosol generator is not working and requires further triggering, such as mouth or nose inhalation, fingerprint or face recognition or other identity recognition, to start heating and atomization, and at this time it is in the standby state.

[0103] In another embodiment, continue to use Figures 2a to 2c As shown in the structural diagram, in this embodiment, the function of opening and closing the airway may or may not be switched, and the function of on and off the switch may or may not be switched. In this embodiment, the function of displaying the working status of the device can be switched by moving the outer shell from the first position to the second position relative to the inner shell.

[0104] Specifically, the function implementation mechanism of this embodiment includes a display element that indicates the working status of the electronic atomization device. When the outer shell is in a first position relative to the inner shell, the effective display area of the display element is shielded, and the electronic atomization device is in a first functional state that does not display the working status; when the outer shell is in a second position relative to the inner shell, the effective display area of the display element is exposed, and the electronic atomization device is in a second functional state that displays the working status of the device.

[0105] For example, the display element is an identification area, which is located on the surface of the inner shell corresponding to the joint surface of the first part and the second part, that is, on the separation area formed by the axial separation of the first part relative to the second part in the foregoing text. The identification can be a LOGO or a pattern, etc., and the identification area has a boundary. When the first part is in the initial first position, it is spliced with the second part, shielding the identification area, and the device is in a first functional state where the identification area is not displayed; when the outer shell moves to the second position relative to the inner shell, the boundary of the identification area is revealed, indicating that the second position has been reached. At this time, the electronic atomization device is in a second functional state where the identification area is displayed.

[0106] Alternatively, the display element is a display screen element, which obtains parameters related to the working state of the electronic atomization device through electrical components, such as the temperature of the aerosol generator, the remaining amount of aerosol generating material, the number of remaining puffs, the power level of the power supply, and other information, and displays this information on the screen. For example, the display screen element is located on the outer surface of the inner shell corresponding to the joint surface of the first part and the second part, that is, on the separation area. When the first part of the outer shell is in the first position, it is spliced with the second part, blocking the display screen element; when the first part moves to the second position, it is separated from the second part, and the display screen element is exposed, thereby displaying the working state of the device.

[0107] Alternatively, the display element is a lighting element, and the light emitted by the lighting element changes on and off, flickers, dims, or changes color depending on the operating state of the electronic atomization device. For example, the light is on when the aerosol generator is operating and off when it is not operating, or flickers when the remaining amount of aerosol-generating material is low. In the first functional state, the light element can be obscured or revealed by directly obscuring or revealing the lighting element, preventing it from displaying the device's operating state, or by obscuring or revealing the light emitted by the lighting element, particularly when the light is directed through a certain light-guiding element. That is, the effective display area of the lighting element is at least a portion of the light it emits. For example, the lighting element can be located below the upper end surface of the inner housing, and the light can be reflected laterally to emerge from the vent at the end of the first portion. Therefore, when the first portion is axially separated from the second portion and positioned in the second position, the vent is no longer blocked, forming a drop area between the end where the vent is located and the end of the inner housing. The light of the lighting element can then be revealed in this drop area, indicating the corresponding operating state of the device.

[0108] The aforementioned functions do not necessarily need to be implemented separately in different embodiments; they may be combined in two or three ways to achieve a single structural solution. For example, the aforementioned first portion can be separated and displaced relative to the second portion to simultaneously open the air inlet and outlet, triggering a switch to activate the aerosol generator. Furthermore, the separated area enclosed by the displacement can be used for display, such as providing a logo or lighting. Therefore, this document does not limit this function.

[0109] In the above-mentioned embodiments, the shell is cylindrical as an example. Ordinary technicians in this field can easily think of using structures of other shapes to implement it. For example, the outer contour of the shell is a triangular prism or a quadrangular prism, but the actual movement trajectory inside it is still similar to the embodiment of rotating the first part to perform spiral movement, which is still within the scope of protection of the present invention.

[0110] Example 2:

[0111] Figure 3a to Figure 3bWhat is shown is a structural diagram of the electronic atomization device of the second embodiment. Similar to the first embodiment, the shell of this embodiment also includes an inner shell 20 and an outer shell 10, and the outer shell includes a first part 12 and a second part 14. Other structural and functional features not described below can refer to the first embodiment and the previous description, and will not be repeated here.

[0112] In this embodiment, the device is an overall rectangular cylinder. The first portion 12 and second portion 14 of the outer housing 10 are axially joined, with the joining surface 13 being a curved surface. Unlike the previous embodiment, the first portion 12 of this invention moves linearly relative to the second portion 14 and the inner housing 20 from the first position to the second position, rather than rotating or spiraling around the axis. Instead, it moves linearly relative to the second portion 14 in the axial direction, separating from the second portion 14 and thereby forming a separation zone.

[0113] The relative movement between the inner shell 10 and the outer shell 20 can be achieved through a certain transmission mechanism, such as a key and keyway mechanism, a slide rail and slide groove mechanism, or it can be achieved without a transmission mechanism and only through a certain limiting structure, such as the longitudinal limiting constraint formed by the edges of the rectangular body plus the distance limiting point set inside the shell, etc., which will not be further elaborated here.

[0114] Similar to the first embodiment, a vent hole 11 is provided at the end of the first portion 12. Before the relative movement, the vent hole 11 is blocked by the raised structure 22 on the inner shell. After the relative displacement, the end of the first portion 12 moves upward and away from the raised structure 22, so that the vent hole 11 is connected to the inner and outer atmosphere of the outer shell 10 and becomes an air outlet 15.

[0115] Similar to the first embodiment, when the first part 12 is in the first position, it and the second part 14 form a closed space before relative movement, and the air vent 11 is blocked by the inner shell, so that the airway of the aerosol generator is blocked from the atmosphere, and the electronic atomization device is in the first functional state of closed airway; when moving to the second position, the separation area between the first part 12 and the second part 14 forms an air inlet 21, and the hole-shaped area at the end of the first part forms an air outlet 15, and the air inlet 21 and the air outlet 15 are connected to the airway, and the electronic atomization device is in the second functional state of open bridge.

[0116] Moreover, in this embodiment, the first embodiment, and other feasible embodiments, the hole-shaped area is arranged at one end portion of the first part. Obviously, the air inlet and the air outlet can also be replaced. For example, the separation area between the first part and the second part is used for air outlet, and the positions of the corresponding air inlet and air outlet, and the inlet and outlet of the air duct can also be replaced accordingly.

[0117] Similar to the first embodiment, the separation area between the first part and the second part and the drop area after the first part is displaced relative to the inner shell can also be used for other functions, such as display function, for displaying lights, display screens, logos, etc., or can also be used as a trigger for starting / closing a switch, or other functional control based on displacement detection, refer to the description of the first embodiment.

[0118] Example 3:

[0119] Figures 4a to 4b 3 is a schematic structural diagram of an electronic atomization device according to a third embodiment of the present invention. Different from the above embodiments, the shell of this embodiment includes an inner shell 20 and an outer shell 10, wherein the outer shell 10 is an integrated structure.

[0120] In this embodiment, the outer shell 10 is tubular and is sleeved on the outer circumferential surface of the inner shell 20 to partially cover the inner shell 20. The atomization chamber and the aerosol generator are located in the inner shell, or the atomization chamber and the inner shell are an integrated structure so that the wall of the atomization chamber is part of the inner shell 20.

[0121] Figure 3a This is the state when the outer shell of this embodiment is in the first position. One end of the outer shell 10 has a beveled surface 110, and the beveled surface 110 forms a notch at the end of the outer shell 10, and the notch constitutes an air outlet. The other end of the outer shell 10 is open and the bottom of the inner shell 20 is exposed from here. An airway is provided on the inner shell 20, and the airway has an inlet and an outlet 210. In this first position, the inlet and outlet 210 of the airway are both located in the enclosing area of the outer shell 10 and isolated from the atmosphere. At this time, the electronic atomization device is in the first functional state of airway closure.

[0122] When the device needs to be started, the outer shell 10 is rotated relative to the inner shell 20. For example, the bottom of the inner shell 20 exposed from the outer shell 10 can be pinched and rotated to the second position, such as Figure 3b As shown, one end of the inner shell has a bevel, and after rotation, the bevel is flush with the beveled surface 110 of the outer shell, and the outlet 210 on the bevel of the inner shell 20 is exposed. At this time, the aerosol in the airway can escape through the outlet and be used by the user.

[0123] Furthermore, the lower end of the outer shell 10 also has a beveled surface 111, which is inclined at an angle of 0 to 90 degrees with respect to the axial direction. The notch formed by the beveled surface 111 in the outer shell 10 constitutes an air inlet. The inlet of the airway on the inner shell 20 is located within the space enclosed by the rotation trajectory of the beveled surface 111. Before rotation, the inlet is located within the outer shell 10 and is hidden, thereby isolating it from the atmosphere. After rotation, the inlet is exposed outside the contour space of the outer shell 10, thereby aligning with the air inlet and communicating with the atmosphere. That is, in this second position, the electronic atomization device is in the second functional state of open airway.

[0124] Therefore, through the above structure and the outer shell moving from the first position to the second position relative to the inner shell 20, the inlet and outlet 210 of the air duct can be synchronously aligned or separated with the air inlet and air outlet of the outer shell 10 respectively, thereby realizing the opening and closing of the air duct, that is, realizing the switching of the electronic atomization device from the first functional state to the second functional state.

[0125] In this embodiment, the air outlet is a beveled surface 110, but it is obvious that in order to achieve the purpose of the present invention of exposing a new area by rotation, the lower end of the outer shell here is not necessarily a beveled surface 111. As long as there is a distance from a partial area in each area of the lower end surface to a cross section perpendicular to the axial direction that is not equal to the distance from other areas of the lower end surface to the cross section, the air duct inlet and / or outlet located on the inner shell 20 is rotated out of the covering area of the outer shell 10 after the outer shell moves to the second position to thereby be exposed, such a structure can achieve the purpose of the present invention.

[0126] Another way is that the outer shell 10 may be provided with a hole-shaped air inlet and air outlet, and the inner shell 20 is also provided with an air duct inlet and outlet. When the outer shell is in a first position relative to the inner shell, the air inlet and air outlet are misaligned with the inlet and outlet, thereby blocking the air duct from the air outside the outer shell, so that the electronic atomization device is in a first functional state in which the air duct is closed; and when the outer shell is rotated to the second position, the air inlet and air outlet are respectively aligned with the inlet and outlet of the air duct, so that the air duct is connected to the external atmosphere, so that the electronic atomization device is in a second functional state in which the air duct is open.

[0127] To ensure airtightness, the spacing between the inner surface of the outer shell 10 and the outer surface of the inner shell 20 is preferably less than 0.5 mm to reduce air ingress. Alternatively, the outer shell 10 can be made of a relatively elastic material such as plastic or rubber, and directly fit over the inner shell 20 in surface contact, thereby ensuring airtightness. Alternatively, seals can be provided between the air inlet and the inlet, and between the air outlet and the outlet, to achieve airtightness.

[0128] Similarly, other structural and functional features not described in this embodiment can refer to all the corresponding descriptions above. For example, the exposed inner shell slope and the bottom area of the outer surface as new areas generated by relative displacement can also be used for display functions, switch activation or other control-related detection functions, etc. For details, please refer to the above embodiments and will not be repeated in this article.

[0129] The above embodiments further illustrate the structure, function and beneficial effects of the electronic atomization device of the present invention. It is easy for ordinary technicians in this field to combine, replace and modify based on the above structure and / or function. As long as they do not exceed the inventive concept of the present invention, they are within the scope of protection of the present invention.

[0130] In summary, in the present invention:

[0131] On the one hand, the electronic atomization device of the present invention switches from a first functional state to a second functional state by moving the outer shell from a first position to a second position relative to the inner shell; the function here can be any function related to the operation of the electronic atomization device, such as display, airway, switch, etc. As long as the function switching is achieved by the position transfer of the inner and outer shells, it falls within the scope of protection of the present invention.

[0132] On the other hand, the present invention also includes an electronic atomization device. Before use, its outer shell is in a first position. At this time, the ambient atmosphere is isolated from the atmosphere inside the shell by cooperating with the inner shell, so that a closed space is formed inside the outer shell, and the device is in a first functional state with the airway closed. When it is needed, the outer shell moves to a second position. At this time, an air inlet channel and an air outlet channel connected to the airway atmosphere are formed on the outer shell and / or the inner shell. The use of this solution can effectively avoid oil leakage and improve user experience.

[0133] On the other hand, the present invention also protects an electronic atomization device. When the outer shell is in the first position, the electronic atomization device is in a first functional state where no atomization operation is performed, which can be a power-off state or a power-on state; when the outer shell moves to a second position relative to the inner shell, the device enters a second functional state where atomization operation or waiting for atomization operation is performed.

[0134] Furthermore, when switching the functional state of the atomization operation, the electronic atomization device of the present invention also includes determining whether the displacement starting point of the outer shell when moving to the second position is the first position. If so, the device switches to the second functional state; if not, the device maintains the first functional state.

[0135] Furthermore, when the outer shell moves from the first position to the second position so that the electronic atomization device enters the second functional state, and the second functional state is the state in which the aerosol generator performs atomization work, the electronic atomization device of the present invention further includes a time detection element to detect the duration of the second functional state, or detect the time the outer shell stays since reaching the second position, and stop the atomization work when the time reaches a preset value.

[0136] On the other hand, the present invention also protects an electronic atomization device. When the outer shell is in the first position, it as a whole or cooperates with the inner shell to form a closed space so that the air inside the electronic atomization device is isolated from the atmosphere outside the shell, and the aerosol generator does not work at this time. This is the first functional state of the device; when the outer shell moves to the second position relative to the inner shell, an air inlet channel and an air outlet channel are formed on the outer shell or between the outer shell and the inner shell. The air inlet channel and the air outlet channel connect the airway of the inner shell with the atmosphere, and at this time the aerosol generator starts to work or enters a standby state. This is the second functional state of the device; using this solution, the patient only needs one action to open the airway and start the aerosol generator at the same time, which can maximize convenience for the patient and reduce usage operations.

[0137] Furthermore, the electronic atomization device of the present invention is preferably a nasal atomization device. That is, in the aforementioned embodiments, the area where the aerosol escapes from the housing and is directly inhaled by the user is the nasal inhalation portion, i.e., the outlet or air outlet mentioned above. The user draws the aerosol by bringing their nasal cavity close to the outlet. As a nasal atomization product, compared to oral atomization, new technical challenges arise when designing operating parameters and characteristics, thus requiring new solutions.

[0138] First, the aerosol escapes to the nasal inhalation part, where the temperature of the aerosol is lower than 55 degrees Celsius. This temperature can be measured by placing a temperature sensor in the nasal inhalation part without affecting normal puffing. Because the nasal cavity's tolerance to temperature is much lower than that of the oral cavity, the operating temperature of the nasal inhalation part in the present invention is lower than 55 degrees Celsius, and is generally preferably lower than 48 degrees Celsius. In the present invention, during use, the temperature of the nasal inhalation part can be limited to a certain range through normal puffing action, because puffing can take away some heat. Therefore, the temperature of the nasal inhalation part here is measured in the puffing state, and the measurement is made by placing the temperature sensor in the nasal inhalation part in the standard mode (ISO mode) of the smoking cycle simulator (SCS). However, in actual design, it is preferred to control the temperature of the aerosol generator or the temperature of the nasal inhalation part. For example, the aerosol generator will not be allowed to continue working for a long time without inhalation, which will cause its heat accumulation and excessive temperature. Therefore, certain measures will be taken, such as temperature monitoring and intelligent power adjustment, or directly making the aerosol generator stop working after a certain period of time until the next start. Therefore, preferably, the temperature of the nasal inhalation part of this device never exceeds 55 degrees Celsius, regardless of whether it is under normal inhalation conditions. In this case, measurement means that after the device is started, the temperature sensor is directly placed in the nasal inhalation part to detect the temperature, and the temperature should never exceed 55 degrees Celsius. For oral inhalation atomization devices, this is different, because the temperature at the mouthpiece of the mouth-inhalation device is at least higher than this range when inhaling or not inhaling, because the mouth-inhalation device has a relatively high tolerance for temperature.

[0139] In addition, since the present invention adopts the principle of heating evaporation, the temperature will usually reach above 200 degrees Celsius, and then be condensed and mixed with the air to form an aerosol within a very short time and distance, and finally escape to the nasal inhalation part, so it will still maintain a certain temperature. Especially when the device of the present invention is hand-held, its small size makes the cooling path shorter, and the degree of temperature reduction is limited. The lower limit of the temperature is 25 to 30 degrees Celsius.

[0140] To achieve miniaturization, the distance between the heating surface of the aerosol generator and the surface where the opening of the nasal inhalation hole is located is 0.5 to 3 cm, preferably 0.8 to 2.0 cm. The temperature during escape is not too low. By adjusting the distance at different values, the inventors found that the escape temperature was consistently above 30 degrees Celsius. The heating surface here refers to the surface of the aerosol generator that vaporizes the medical liquid, such as the surface where the heating wire resides. If there are multiple such surfaces, the one closest to the nasal inhalation hole is used for calculation. If there are multiple distances from this surface to the nasal inhalation hole, the closest point is used for calculation.

[0141] Furthermore, because the inhaler is designed for the nasal cavity, and the nostrils are much smaller than the mouth, the openings in the inhaler for aerosol escape should be as small as possible, preferably with a radial dimension less than 20 mm, to ensure that the aerosol does not escape excessively. In some embodiments, the inhaler preferably has circular, oval, or other similarly shaped openings, preferably with an aperture diameter less than 12 mm.

[0142] The nasal inhalation portion is the portion that delivers the above-mentioned aerosol to the nasal cavity. It can be set at the end of the shell, or it can be located on the outer surface of the shell, for example, it can be located in the middle of the outer surface of the cylindrical shell, or it can be located on the end surfaces of both ends, or other positions. The nasal inhalation portion is usually in the shape of a hole to allow the aerosol to escape, or it can be in the shape of a cavity, which can accommodate a certain amount of aerosol. The nasal inhalation portion is located on the shell area on the outer surface of the entire device, or the shell can have an outer shell and an inner shell, and the hole-shaped area on the inner shell extends to the outer shell or outside the outer shell to form the nasal inhalation portion. For example, the end of the inner shell has a straw shape, which can extend from the inside of the device to the outside of the outer shell for the user to approach and use.

[0143] Furthermore, for portability, the device is preferably hand-held, meaning that the entire device can be grasped by a single hand. The housing is preferably cylindrical, having an axially extending side surface and end surfaces at either end of the side surface. Generally, the axially extending length of the side surface is greater than the radial dimension of the end surface. The cylindrical housing may be cylindrical, square, polygonal, or any other regular or irregular shape.

[0144] To facilitate palm-sized grip, the housing is preferably an elongated cylindrical shape. For example, the axial length of the housing is at least three times the radial dimension of its cross-section. The cross-section of the housing refers to a section taken perpendicular to the axial direction. If the cross-sections of the housing along the axial direction are not constant, the cross-section with the average area is used. If there are multiple such cross-sections, the cross-section near the midpoint of the axial length is used. For a square cross-section, the radial dimension is the side length of the cross-section; for a circular cross-section, the radial dimension is the diameter of the circle; for a cross-section that is neither square nor circular, the radial dimension is the square root of the cross-sectional area. Furthermore, to prevent the device from being too slender and difficult to grasp, the axial length of the housing is preferably less than or equal to eight times the radial dimension of the cross-section.

[0145] After thorough research into user hand sizes and patient usage habits, the inventors of this invention ultimately designed the housing's axial length to be between 40 and 120 mm, preferably between 50 and 80 mm. This length allows the user's thumb and index finger to pinch the upper portion of the device, while also positioning the lower end roughly under the palm, allowing for both contact and friction with the palm while also resting squarely against it, giving the user a sense of control. Furthermore, the diameter encompassed by a palm grip generally ranges from 10 to 30 mm. Therefore, when designing this medical nasal suction device, a radial dimension of 12 to 20 mm, for example, 14 to 18 mm, is preferred.

[0146] In addition, in order to better grasp, a hand-held portion can be designed on the surface of the shell, and the hand-held portion has a protruding, concave or undulating curved surface to increase the friction with the palm.

[0147] Of course, the device of the present invention does not necessarily need to be manufactured to the size and shape restrictions of the handheld device described above. The above is only the best embodiment. Within the scope of various application scenarios and product design space, the device can be made relatively larger in size. Regardless of the size, as long as the user inhales the aerosol through nasal inhalation and the aerosol escapes from the device by evaporation due to heating for inhalation by the user, it is an electronic atomization device to be protected by the present invention.
