[0001] The present application relates to the technical field of electronic atomization, in particular to an atomizing nozzle, an atomizer and an atomizing device. BACKGROUND

[0002] An atomizing device can atomize an aerosol generating substrate for a user to use. Generally, the atomizing nozzle of an atomizing device storing an aerosol generating substrate has a gas outlet channel that is always open.

[0003] During long-term use, dust and impurities tend to accumulate in the open gas outlet channel, which needs to be cleaned regularly by the user. In addition, the open gas outlet channel can cause the aerosol generating substrate inside the atomizing device to volatilize, resulting in a decrease in the taste concentration and a deterioration in the taste of the user. UTILITY MODEL CONTENT

[0004] The present application provides an atomizing nozzle, an atomizer and an atomizing device to solve the problems of dust accumulation and substrate volatilization in the gas outlet channel of an atomizing device.

[0005] In one embodiment, an atomizing nozzle is provided, comprising:

[0006] a main body defining a gas outlet channel;

[0007] a blocking member selectively arranged at a first assembly position or a second assembly position on the main body;

[0008] When the blocking member is at the first assembly position of the main body, the blocking member blocks the gas outlet channel; when the blocking member is at the second assembly position of the main body, the gas outlet channel is open at both ends.

[0009] In some embodiments, at least part of the blocking member is in a columnar shape; when the blocking member is at the first assembly position of the main body, at least part of the columnar structure of the blocking member is inserted into the gas outlet channel to block the gas outlet channel.

[0010] In some embodiments, when the blocking member is at the first assembly position of the main body, the blocking member is in interference fit with the main body;

[0011] and / or, a sealing ring is arranged on the peripheral side of the blocking member.

[0012] In some embodiments, the main body further defines an assembly groove; when the blocking member is at the second assembly position of the main body, the blocking member is located in the assembly groove, and the gas outlet channel is open at both ends.

[0013] In some embodiments, when the blocking member is at the second assembly position of the main body, the blocking member is in interference fit with the groove wall of the assembly groove.

[0014] In some embodiments, the main body comprises a main body portion and a gas guide portion, the gas guide portion defines the gas outlet channel, and the main body portion is arranged circumferentially around the gas guide portion.

[0015] The main body portion and the gas guide portion jointly define a cavity which is closed at a first end and open at a second end.

[0016] In some embodiments, the main body portion comprises a top wall which is annular, and a side wall which is cylindrical; the inner periphery of the top wall is connected to the end of the gas guide portion, and the outer periphery of the top wall is connected to the end of the side wall; the top wall is axially recessed to form an assembly groove; when the sealing member is in the second assembly position of the main body, the sealing member is located in the assembly groove, and the gas outlet channel is open at both ends.

[0021] The nebulizing nozzle, the nebulizer and the nebulizing device according to the above embodiments can be used to control the conduction and the closure of the gas outlet channel by the sealing member. By arranging the first assembly position on the main body, the gas outlet channel can be closed when the user does not use the nebulizing nozzle, so as to avoid as much as possible the dust and other impurities in the environment from entering the nebulizing nozzle through the gas outlet channel, and even entering the nebulizer or the nebulizing device which is in communication with the nebulizing nozzle.

[0022] By closing the gas outlet channel, the air passage in the nebulizer or the nebulizing device which is in communication with the gas outlet channel is closed, the volatilization of the aerosol generating substrate in the nebulizer or the nebulizing device is reduced, and the consistency of the taste in the process of multiple puffs is prolonged.

DETAILED DESCRIPTION

[0030] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following embodiments, many details are described in order to provide a better understanding of the application. However, a person skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for a person skilled in the art according to the description in the specification and general technical knowledge in the art.

[0031] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to a person skilled in the art. Therefore, the order in the specification and the drawings is only for the purpose of clearly describing a certain embodiment, and does not mean that it is the necessary order, unless otherwise stated that a certain order must be followed.

[0032] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meaning. The "connection" and "coupling" in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0033] As shown in Figure 1 and Figure 2 , the application provides an atomizing nozzle 1 which can be matched with components such as an atomizer 2 or an atomizing device for a user to smoke aerosol.

[0034] It needs to be understood that the atomizer 2 or the atomizing device contains liquid aerosol generating substrate. During use, the liquid aerosol generating substrate can be heated and atomized to form aerosol. The aerosol can follow the airflow generated by the user's suction and flow to the atomizing nozzle 1 and be output for the user to use.

[0035] The atomizing nozzle 1 can include a main body 10 and a blocking piece 20. The main body 10 defines an air outlet channel 121. When the atomizing nozzle 1 is used with the atomizer 2 or the atomizing device, the air outlet channel 121 can be in communication with the air passage in the atomizer 2 or the atomizing device. The aerosol generated in the atomizer 2 or the atomizing device can follow the user's suction and flow out of the air outlet channel 121 for the user to use.

[0036] The blocking piece 20 can be selectively arranged on the first assembly position or the second assembly position of the main body 10. As shown in Figure 4 , when the blocking piece 20 is located at the first assembly position of the main body 10, the blocking piece 20 can block the air outlet channel 121. As shown in Figure 5 , when the blocking piece 20 is located at the second assembly position of the main body 10, both ends of the air outlet channel 121 are penetrated.

[0037] By arranging the blocking piece 20, the user can independently control the conduction and closing of the air outlet channel 121. By arranging the first assembly position on the main body 10, the air outlet channel 121 can be blocked when the user does not use the atomizing nozzle 1 (atomizer 2 or atomizing device), so as to avoid as much as possible the dust and other impurities in the environment during storage from entering the atomizing nozzle 1 through the air outlet channel 121, and even entering the atomizer 2 or the atomizing device connected thereto. In addition, by blocking the air outlet channel 121, the air passage in the atomizer 2 or the atomizing device connected with the air outlet channel 121 is blocked, the volatilization of the aerosol generating substrate in the atomizer 2 or the atomizing device is reduced, and the consistency of the taste in the process of multiple suction is prolonged.

[0038] By arranging the second assembly position on the main body 10, the blocking piece 20 can be temporarily stored during the user's suction, so as to avoid potential problems such as easy loss of the blocking piece 20 caused by being placed alone.

[0039] It should be understood that the first assembly position and the second assembly position can be a single fixed position or a non-single fixed position.

[0040] As shown in FIGS. 1 and 2, in some embodiments, the plug 20 can be at least partially cylindrical, and the first assembly position can be the gas outlet end of the gas outlet passage 121 or the first assembly position can be defined by the sidewall of the gas outlet passage 121. When the plug 20 is in the first assembly position of the main body 10, at least a portion of the cylindrical structure of the plug 20 is inserted into the gas outlet passage 121 to seal the gas outlet passage 121. Figure 1 Figure 2 As shown in FIGS. 1 and 2, in some embodiments, the plug 20 can be at least partially cylindrical, and the first assembly position can be the gas outlet end of the gas outlet passage 121 or the first assembly position can be defined by the sidewall of the gas outlet passage 121. When the plug 20 is in the first assembly position of the main body 10, at least a portion of the cylindrical structure of the plug 20 is inserted into the gas outlet passage 121 to seal the gas outlet passage 121.

[0041] Further, when the plug 20 is in the first assembly position of the main body 10, the plug 20 can be in interference fit with the main body 10 to ensure the sealing performance of the gas outlet passage 121.

[0042] For example, the plug 20 can be entirely cylindrical, and the cross-sectional dimension of the plug 20 can gradually change along the axial direction. The cross-sectional dimension of a portion of the plug 20 can be equal to or less than the cross-sectional dimension of the gas outlet passage 121, and the cross-sectional dimension of the remaining portion of the plug 20 can be greater than the cross-sectional dimension of the gas outlet passage 121. When the plug 20 is inserted into the gas outlet passage 121, a portion of the plug 20 can be located inside the gas outlet passage 121, and a portion of the plug 20 can be located outside the gas outlet passage 121.

[0043] For another example, the plug 20 can further include at least one sealing ring arranged on the main body portion of the plug 20 to seal the gap between the main body portion of the plug 20 and the gas outlet passage 121 when the plug 20 is inserted into the gas outlet passage 121. The sealing ring can be arranged at any position along the axial direction of the plug 20, which is not specifically limited herein.

[0044] When the user needs to use the atomizing mouthpiece 1, the shape and size of the plug 20 can facilitate the user to remove the plug 20 from the gas outlet passage 121 by grabbing the cylindrical segment located outside the gas outlet passage 121. In this embodiment, when the plug 20 is inserted into the gas outlet passage 121, the user can also control the force to achieve the interference fit between the plug 20 and the sidewall of the gas outlet passage 121, thereby improving the sealing performance of the plug 20.

[0045] ​In some alternative embodiments, the blocking member 20 can further comprise a top wall arranged at the top end of the columnar structure. When the blocking member 20 is in the first assembly position of the main body 10, the columnar structure of the blocking member 20 is inserted into the air outlet passage 121, and the top wall is arranged at the top end of the air outlet passage 121 and can be arranged in abutment with the outer wall of the main body 10. When the user needs to use the atomizing mouthpiece 1, the top wall outside the air outlet passage 121 can be pulled to remove the blocking member 20 from the air outlet passage 121.

[0046] In some embodiments, the blocking member 20 can be inserted into the partial section of the air outlet passage 121, and at least one annular protruding rib can be arranged to realize the interference fit between the blocking member 20 and the side wall of the air outlet passage 121, thereby further improving the sealing performance of the air outlet passage 121.

[0047] In some alternative embodiments, the blocking member 20 can be integrally arranged in a cover-like structure. When it is in the first position of the main body 10, it can be arranged on the main body 10 and block the air outlet passage 121. In this embodiment, the blocking member 20 can be assembled with the main body 10 by interference fit, and can be assembled with the main body 10 by a buckle structure or other connecting structure, which is not limited herein.

[0048] It should be understood that when the blocking member 20 is in the first assembly position of the main body 10, the "blocking" of the air outlet passage 121 can be understood as sealing, or can be understood as shielding the outlet of the air outlet passage 121 to a certain extent. For example, when the blocking member 20 is arranged in a cover-like manner on the main body 10, the arrangement state can not completely seal the air outlet passage 121. However, the arrangement of the blocking member 20 at the outlet of the air outlet passage 121 can reduce the volatilization of the aerosol generating substrate to a certain extent and prevent dust and impurities from entering the air outlet passage 121. For another example, when the blocking member 20 is arranged in a columnar structure and is interference-fitted with the side wall of the air outlet passage 121, the air outlet passage 121 can be sealed by the blocking member 20, which can further prevent the volatilization of the aerosol generating substrate.

[0049] It should be understood that the blocking member 20 can be at least partially made of a material with certain elastic properties, such as rubber, to facilitate the interference fit.

[0050] In some embodiments, the main body 10 further defines an assembly groove 111. When the blocking member 20 is in the second assembly position of the main body 10, the blocking member 20 is arranged in the assembly groove 111, and the air outlet passage 121 is through at both ends.

[0051] By setting the assembly groove 111, a temporary storage space can be provided for the blocking piece 20. When the user needs to use the atomizing nozzle 1 (the blocking piece 20 is taken out from the first assembly position), the blocking piece 20 can be placed in the assembly groove 111 to avoid the loss of the separately arranged blocking piece 20.

[0052] In other optional embodiments, the atomizing nozzle 1 can further include a flexible connecting piece, one end of which is connected to the main body 10 and the other end of which is connected to the blocking piece 20. When the blocking piece 20 is taken out from the first assembly position of the main body 10, the blocking piece 20 is arranged on the main body 10 through the connecting piece to avoid the loss of the blocking piece 20. At this time, it can also be considered that the blocking piece 20 is in the second assembly position. In this embodiment, since the connecting piece is flexible, the second assembly position of the blocking piece 20 is not unique.

[0053] In some embodiments, when the blocking piece 20 is in the second assembly position of the main body 10, the blocking piece 20 can be in interference fit with the groove wall of the assembly groove 111 to facilitate the positioning of the blocking piece 20 in the assembly groove 111. The risk of the blocking piece 20 being taken out of the assembly groove 111 and lost is reduced.

[0054] In other optional embodiments, the main body 10 can also be provided with an assembly cavity instead, which can include a closable opening. When the blocking piece 20 is arranged in the second assembly position of the main body 10, the blocking piece 20 can be located in the assembly cavity through the opening, and the blocking piece 20 can be limited in the assembly cavity by closing the opening to avoid being taken out and lost. In this embodiment, the cavity wall of the assembly cavity and the blocking piece 20 can be in interference fit or non-interference fit.

[0055] As shown in Figure 2 In some embodiments, the main body 10 can include a main body part 11 and a gas guide part 12. The gas guide part 12 defines the gas outlet channel 121. The main body part 11 is circumferentially arranged around the gas guide part 12 and, together with the gas guide part 12, defines a cavity 112 which is closed at a first end and penetrable at a second end. The first end and the second end are opposite ends of the cavity 112.

[0056] The main body part 11 circumferentially arranged around the gas guide part 12 can be regarded as the shell of the main body 10. By making the main body part 11 and the gas guide part 12 together define the cavity 112, the main body part 11 and the gas guide part 12 can be at least partially spaced apart. During use by the user, the influence of the airflow with a certain temperature on the user can be reduced, the touch temperature of the atomizing nozzle 1 can be prevented from being too high, and the user experience can be improved.

[0057] The main body 10 can be generally flat and cylindrical. The air guide 12 can be cylindrical with both ends open. The main body 11 can include a top wall and side walls. The top wall is annular, and the side walls are cylindrical. The inner circumference of the annular top wall is connected to the top end of the air guide 12, and the outer circumference is connected to the top end of the cylindrical side wall. The side walls of the main body 11 surround the air guide 12 circumferentially and are spaced apart from the air guide 12.

[0058] In this embodiment, the air guide 12 is generally cylindrical, defining an air outlet channel 121 with a circular cross-section, and is coaxially arranged with the main body 11. The sealing member 20 is correspondingly cylindrical. The horizontal cross-sectional outer contour of the main body 11 is generally elliptical, resembling a runway.

[0059] like Figure 4 and Figure 5 As shown, the common axis of the main body 11 and the air guide 12 is defined as axis M. Then, the first end and the second end of the cavity 112 can be respectively the two opposite ends along the direction of axis M. The first end of the cavity 112 is defined as the top end of the cavity 112, and the second end is defined as the bottom end of the cavity 112.

[0060] In some other optional embodiments, the air guide 12 may be arranged parallel to and spaced apart from the axis of the main body 11, or the axes of the two may be arranged at a certain angle. The air guide 12 may also be configured as a bent or curved tubular structure. The shape of the air guide 12 may also be configured as a polygonal tubular shape. The cross-sectional shape of the air outlet channel 121 may also be configured as a polygon, ellipse, irregular shape, or other shapes. When the sealing member 20 is at least partially inserted into the air outlet channel 121 in a columnar shape, the shape of its cross-section may also be adaptively adjusted to follow the change in the cross-sectional shape of the air outlet channel 121. The cross-sectional profile of the air guide 12 may correspond to the cross-sectional shape of the air outlet channel 121, or it may be configured as a different shape.

[0061] In some other alternative embodiments, the main body 11 and the air guide 12 may also be fitted together to fill the cavity between them.

[0062] In some other alternative embodiments, the main body 10 may also be cylindrical, polygonal columnar, disc-shaped, hemispherical, irregular, or other shapes. The main body portion 11 may be configured with different shapes and structures accordingly.

[0063] like Figure 1 As shown, in this embodiment, the assembly groove 111 can be formed on the top wall of the main body 11, and its shape can also be set to a cylindrical shape so as to correspond to the cylindrical sealing member 20.

[0064] The assembly groove 111 can be arranged parallel to the air outlet channel 121, or can be arranged at an angle with the air outlet channel 121.

[0065] In some alternative embodiments, the assembly groove 111 can also be formed on the sidewall of the main body 11.

[0066] Referring to Figure 2 In some embodiments, the main body 10 can further include an assembly portion 13. The assembly portion 13 can be arranged at the end away from the outlet of the air outlet channel 121, i.e. the bottom end of the main body 11 in the extending direction of the axis M, for assembly with the atomizer 2 or other components of the atomization device.

[0067] The assembly portion 13 can be arranged in a ring shape (or a cylinder shape) and connected to the bottom end of the cylindrical sidewall of the main body 11. The assembly portion 13 can further include at least one snap structure 131 arranged on the inner wall surface or the outer wall surface of the assembly portion 13.

[0068] In some alternative embodiments, the assembly portion 13 can be arranged on the inner wall or the outer wall of the assembly portion 13, and at least one assembly structure such as a protruding rib can be arranged to achieve the assembly effect with other components.

[0069] It should be understood that the assembly structure such as the snap structure 131 or the protruding rib can be arranged on the inner wall surface or the outer wall surface of the assembly portion 13, which needs to be adjusted flexibly according to the structure of the atomizer 2 or the atomization device to be assembled, and is not limited herein.

[0070] As shown in Figure 4 and Figure 5 The present application further provides an atomizer 2 which can include the atomizing nozzle 1 of any of the above embodiments. The atomizer 2 can define an atomization channel 203. The air outlet channel 121 is in communication with the atomization channel 203. The aerosol formed by atomization can flow out through the atomization channel 203 and the air outlet channel 121 in sequence.

[0071] In some embodiments, the atomizer 2 can include a housing 201 and can further define a liquid storage cavity 202. The liquid storage cavity 202 contains an aerosol generating substrate. The main body 10 of the atomizing nozzle 1 can be detachably connected with the housing 201, thereby achieving assembly of the atomizing nozzle 1 with other parts of the atomizer 2.

[0072] Specifically, for the embodiments with the assembly portion 13, the assembly portion 13 can be detachably connected with the housing 201.

[0073] In some embodiments, the atomizer 2 can further include an atomization assembly 204, which can be disposed in the atomization channel 203 and in communication with the liquid storage cavity 202. The atomization assembly 204 is configured to heat the aerosol generating substrate flowing out of the liquid storage cavity 202 to form an aerosol after being powered. The aerosol can flow out through the atomization channel 203 and the air outlet channel 121.

[0074] It should be understood that the liquid storage cavity 202 can be a single cavity or a plurality of pores defined in a porous structure, which is not limited herein.

[0075] As shown in FIG. 1, the present application also provides an atomization device, which can include the atomization mouthpiece 1 of any of the above embodiments. Figures 3 to 5

[0076] In some embodiments, the atomization device can further include the atomizer 2 of any of the above embodiments.

[0077] When the atomizer 2 includes the liquid storage cavity 202 and the atomization channel 203, the atomization device can further include the atomization assembly 204, the power supply module 3, and a housing. The atomization assembly 204 is electrically connected to the power supply module 3 and disposed in the housing. The housing can be detachably connected to the outer shell 201 of the atomizer 2. The power supply module 3 is configured to provide power to the atomization assembly 204. The atomization assembly 204 can be disposed in the atomization channel 203 after assembly or in an air passage in communication with the atomization channel 203 to enable the aerosol to flow out of the atomization channel 203.

[0078] When the atomizer 2 includes the liquid storage cavity 202, the atomization channel 203, and the atomization assembly 204, the atomization device can further include the power supply module 3 and the housing. When the outer shell 201 of the atomizer 2 is assembled with the housing of the atomization device, the atomization assembly 204 in the atomizer 2 can be electrically connected to the power supply module 3 in the atomization device.

[0079] In some embodiments, the atomization device can include only one housing, in which the liquid storage cavity 202, the atomization channel 203, the atomization assembly 204, and the power supply module 3 are disposed. The atomization mouthpiece 1 can be detachably connected to the housing.

[0080] As shown in FIG. 1, the present application also provides an atomization device, which can include the atomization mouthpiece 1 of any of the above embodiments. Figure 4 Figure 5 As shown in FIG. 1, the present application also provides an atomization device, which can include the atomization mouthpiece 1 of any of the above embodiments.

[0081] ​​The air inlet hole 2011 can be in communication with the atomization channel 203, and the air inlet hole 2011, the atomization channel 203 and the air outlet channel 121 together define an air passage through the atomization device. In the process of using the atomization device by a user, air can enter the atomization channel 203 through the air inlet hole 2011, and mix with the atomized aerosol in the atomization channel 203 to form a mixed gas, which then enters the air outlet channel 121 and flows out.

[0082] By arranging the air inlet valve 205, the air passage can be closed and opened from both ends by cooperating with the blocking member 20 of the atomization mouthpiece 1. When the atomization device is not used, the air passage can be blocked from both ends to isolate the outside air. Such an arrangement can alleviate the oxidation and metamorphosis of the aerosol generating substrate.

[0083] In some embodiments, the air inlet valve 205 is movably arranged on the shell 201. The moving path of the air inlet valve 205 can include a first moving position and a second moving position. When the air inlet valve 205 is in the first moving position, the air inlet hole 2011 is in communication with the outside. When the air inlet valve 205 is in the second moving position, the air inlet hole 2011 is blocked by the air inlet valve 205.

[0084] Specifically, the air inlet valve 205 can move on the shell 201 by arranging a guide rail groove on the shell 201, so that the air inlet valve 205 moves back and forth along the extension direction of the guide rail. Alternatively, a rotating shaft can be arranged on the shell 201, so that the air inlet valve 205 rotates back and forth around the rotating shaft. No specific limitation is made herein.

[0085] In other optional embodiments, the air inlet valve 205 and the shell 201 can be detachably connected. When the air inlet valve 205 is in the first moving position, the air inlet valve 205 is separated from the shell 201, and the air inlet hole 2011 is in communication with the outside. When the air inlet valve 205 is in the second moving position, the air inlet valve 205 is assembled to the shell 201, and the air inlet hole 2011 is blocked by the air inlet valve 205.

[0086] The above application of specific examples is used to illustrate the present application and is not intended to limit the present application. According to the idea of the present application, those skilled in the art can make several simple deductions, modifications or substitutions.
