Referring to fig. 1 to 3, and referring to fig. 4 and 5, in some embodiments of the present application, an atomizer 100 is provided, the atomizer 100 includes a main body 100a and a nozzle assembly 10, the main body 100a has a liquid storage chamber 20a, the nozzle assembly 10 includes a base 11 and an atomizing member 12, the base 11 has a nozzle 13, the base 11 is configured with an atomizing channel 11a, the nozzle 13 is located at an outlet side of the atomizing channel 11a, and the atomizing member 12 is at least partially located in the atomizing channel 11 a. Wherein the base 11 is configured to be detachably assembled with the main body 100a, and the liquid storage chamber 20a communicates with the inlet a2 of the atomizing passage when the two are assembled together.

The reservoir 20a is a space on the body 100a for storing a liquid aerosol-generating substrate. When the nozzle assembly 10 is assembled to the body 100a, the aerosol-generating substrate within the reservoir 20a is able to flow into the nebulization channel 11a of the cartridge 11. Further, the main body 100a serves as a mounting base of the nozzle assembly 10, and when the nozzle assembly 10 is mounted to the main body 100a, the main body 100a can supply power to the atomizing member 12 to support the atomizing member 12 for atomizing operation.

In the present embodiment, the housing 11 includes the nozzle 13, that is, the atomizing passage 11a may be provided to extend into the interior of the nozzle 13. Of course, the atomizing passage 11a may not extend into the nozzle 13.

The nozzle 13 may be made of soft rubber (such as silica gel, rubber, etc.), so as to be convenient for sealing and fitting with the face (including mouth, nose, etc.) of the user. The atomizing member 12 may be configured as an atomizing sheet, an atomizing net, an atomizing block, or the like, and is not particularly limited. The atomizing member 12 may be a resistive atomizing member 12, an ultrasonic atomizing member 12, a piezoelectric atomizing member 12, or the like, and the specific atomizing manner of the atomizing member 12 is not limited in the embodiment of the present application, as long as the atomizing function can be achieved. Illustratively, the atomizer 12 includes liquid-conducting wool disposed within the atomizing channel 11a and a resistive heating wire disposed on the liquid-conducting wool. Also illustratively, the atomizing member 12 comprises an ultrasonic micro-mesh atomizing sheet.

The nozzle 13 can be detachably arranged as a single structure on the base 11, so that the nozzle 13 can be replaced independently, and the nozzle 13 and the base 11 can be replaced together. The atomizing piece 12 and the base 11 may be detachably connected, so that the atomizing piece can be replaced independently, or may be fixedly connected, and the atomizing piece 12 and the base 11 are replaced together, which is not limited in the embodiment of the present application.

The seat 11 is detachably connected to the main body 100a, specifically, may be detachably connected by a buckle, may be detachably connected by a screw thread, or may be detachably connected by other means, and the specific means is not limited in the embodiment of the present application.

Above-mentioned atomizer 100, atomizing piece 12 and nozzle 13 integrate on this removable module of nozzle assembly 10, when needs change atomizing piece 12/nozzle 13, only need with this module of nozzle assembly 10 follow main part 100a detach can, the nozzle assembly 10 of detaching does not include stock solution structures such as stock solution cup 20, can not cause the waste and the consumption of stock solution structures, can reduce the consumable cost that produces in the atomizer 100 use, alleviate the waste of consumptive material.

In some embodiments, referring to fig. 2 and 3, the main body 100a has a mating portion 20b, the base 11 has a knob portion 11b rotatably sleeved on the mating portion 20b about a set axial direction X, and the knob portion 11b is configured to switch between a first position in which the two portions are separable and a second position in which the two portions are fixed during rotation relative to the mating portion 20 b.

The coupling portion 20b may be integrally formed with the main body 100a, or may be configured as a separate structure on the main body 100a, which is not particularly limited. In practice, the nozzle assembly 10 may be disposed entirely axisymmetrically with respect to the set axial direction X.

The knob portion 11b is not limited to being fitted in the mating portion 20b or being fitted out of the mating portion 20 b. It is understood that the mating portion 20b and the knob portion 11b are each disposed axisymmetrically with respect to the set axial direction X.

The knob portion 11b may be a single member provided on the housing 11, or may be a partial structure of the housing 11. In one embodiment, the base 11 includes a knob portion 11b and a nozzle 13, and the knob portion 11b is rotatably disposed on the nozzle 13 about a set axial direction X with respect to the nozzle 13. In another embodiment, the knob portion 11b and the nozzle 13 are integrally formed as the housing 11. The specific configurations of the base 11, the knob 11b, and the nozzle 13 are not limited in the embodiment of the present application. The rest of the nozzle assembly 10 may rotate along with the knob portion 11b or may remain stationary as the knob portion 11b rotates.

In actual operation, when the nozzle assembly 10 needs to be detached from the main body 100a, the knob portion 11b is turned to the first position, and when the nozzle assembly 10 is installed, the knob portion 11b is sleeved on the coupling portion 20b, and the knob portion 11b is turned to the second position, so that the nozzle assembly 10 is fixed with the main body 100 a.

At this time, the main body 100a and the nozzle assembly 10 can be detached by simply turning the knob portion 11b, which is convenient to operate and contributes to the quick detachment of the nozzle assembly 10 and the main body 100 a.

In some embodiments, the knob portion 11b is configured to generate a set stroke amount in the set axial direction X when switching from one of the first position and the second position to the other.

That is, the knob portion 11b changes its position in the set axial direction X during rotation. Specifically, the arrangement for realizing the rotation of the knob portion 11b around the setting axis direction X while being able to be changed in position in the setting axis direction X may be, but not limited to, that the knob portion 11b is screwed with the mating portion 20 b. The screw thread extends in a spiral shape, and can support the knob portion 11b and the coupling portion 20b to approach each other in the set axial direction X when they are rotated relative to each other. Understandably, when the knob portion 11b is turned to the second position, the fitting length of the knob portion 11b and the mating portion 20b increases.

When the knob portion 11b is changed in position in the set axial direction X in the rotation process, the sleeve length of the knob portion 11b and the mating portion 20b can be changed, when the sleeve length is increased, the knob portion 11b is connected with the mating portion 20b more reliably, and when the sleeve length is reduced, the knob portion 11b can be removed from the mating portion 20b more easily.

Of course, in other embodiments, the knob portion 11b may be rotated about the setting axis X relative to the mating engagement without being rotated in the setting axis X.

In some embodiments, referring to fig. 2, 3 and 6, one of the socket surface of the knob portion 11b and the socket surface of the mating portion 20b has a concave structure 11c, the other has a convex structure 23, the concave structure 11c has an open groove c1 and a guide groove c2, one end of the guide groove c2 is communicated with the open groove c1, and the guide groove c2 has a set length in the set axial direction X. The guide groove c2 is used for guiding the protruding structure 23 to move around the set axial direction X, and the open groove c1 is used for allowing the protruding structure 23 to enter or exit the recessed structure 11c.

The socket surface of the knob portion 11b and the socket surface of the mating portion 20b are both disposed around the set axial direction X. When the knob portion 11b is sleeved in the coupling portion 20b, the sleeved surface of the knob portion 11b is an outer wall surface thereof, and the sleeved surface of the coupling portion 20b is an inner wall surface thereof. When the knob portion 11b is sleeved outside the coupling portion 20b, the sleeved surface of the knob portion 11b is an inner wall surface thereof, and the sleeved surface of the coupling portion 20b is an outer wall surface thereof.

The concave structure 11c is concavely arranged on the socket surface along the radial direction perpendicular to the set axial direction X, and the convex structure 23 is convexly arranged on the socket surface along the radial direction perpendicular to the set axial direction X.

The open groove c1 is in an open form, the protruding structure 23 can enter and exit the recessed structure 11c via the open groove c1, and when the knob portion 11b is rotated to the first position, the protruding structure 23 is located in the open groove c1. When the knob portion 11b is rotated from the first position to the second position, the protruding structure 23 enters the guide groove c2 from the open groove c1, and moves around the setting axial direction X while being guided by the guide groove c2 (i.e., the knob portion 11b changes its position in the setting axial direction X when rotated). The guide track presented by the guide groove c2 may be spiral. The helix angle of the guide slot c2 may be, but is not limited to, less than 90 degrees, i.e. the length of the guide slot c2 may be less than a quarter of a helix length.

When the knob portion 11b is turned to the second position, the projection structure 23 reaches at least partially the end of the guide groove c2 and is restrained from moving by the end. Illustratively, the entirety of the projecting structure 23 can be accommodated in the guide groove c2, and upon rotation of the knob portion 11b, the entirety of the projecting structure 23 can be moved to the distal end thereof along the guide groove c2 and caught at the distal end. The end can be an open end or a closed end, according to the practical situation.

The concave structures 11c and the convex structures 23 may be provided in pairs, and the pairs are at least one pair. When there are a plurality of pairs of concave structures 11c and convex structures 23, each concave structure 11c may be disposed symmetrically with respect to the set axial direction X, and the convex structures 23 may be disposed symmetrically with respect to the set axial direction X. Of course, not limited to this arrangement, the skilled person can flexibly set.

When the nozzle assembly 10 is installed, the knob portion 11b is moved in the set axial direction X until the protruding structure 23 enters the recessed structure 11c through the open groove c1 of the recessed structure 11c, and then the knob portion 11b is rotated so that the protruding structure 23 on the knob portion 11b moves along the guide groove c2, and when the protruding structure 23 reaches the end of the guide groove c2, the knob portion 11b is rotated into place (i.e., into the second position). Conversely, when the knob portion 11b is reversely rotated while the nozzle assembly 10 is disassembled, the protrusion structure 23 moves from the end of the guide to the open groove c1 along the guide groove c2, and when the protrusion structure 23 exits the guide groove c2 and enters the open groove c1, the knob portion 11b is positioned at the first position, the protrusion structure 23 may exit the recess structure 11c, so that the knob portion 11b may be separated from the coupling portion 20 b.

At this time, the fixing of the knob portion 11b and the detachment of the knob portion 11b are facilitated by the movement of the protruding structure 23 within the recessed structure 11 c. Meanwhile, the position of the protruding structure 23 is changed in the set axial direction X during movement, so that the sleeving length of the knob part 11b and the matching part 20b can be changed, and the disassembly and assembly of the knob part 11b and the matching part 20b are facilitated.

The guide groove c2 has a set length in the set axial direction X corresponding to a set formation amount of the knob portion 11b in the set axial direction X.

Further, referring to fig. 6, the guiding groove c2 has a guiding section c21, a compressing section c22 and a working section c23 sequentially arranged, the compressing section c22 is obliquely arranged around the set axial direction X, the guiding section c21 is communicated with the open groove c1, and the groove width of the compressing section c22 decreases in a direction from the guiding section c21 to the working section c 23.

The pressing section c22 is obliquely arranged around the set axial direction X, which means that the pressing section c22 has a certain length in the set axial direction X while being arranged around the set axial direction X, and when the protruding structure 23 moves along the pressing section c22, a position change in the set axial direction X can occur. The groove width of each segment of the guide groove c2 refers to the distance between the opposite inner walls in the set axial direction X.

The introduction section c21 communicates with the open groove c1, and when the mounting base 32 body 11 is mounted on the main body 100a, the protrusion 23 on the knob portion 11b initially enters the open groove c1, and then can smoothly enter the pressing section c22 under the guidance of the introduction section c 21. As the notch of the pressing section c22 continuously becomes smaller, the knob portion 11b continues to rotate toward the second position, the protruding structure 23 is gradually pressed in the pressing section c22, and when the protruding structure 23 enters the working section c23, the pressing degree is not increased and enters the stationary phase, so that the moving resistance of the protruding structure 23 can be reduced, and the user operation is not so laborious.

At this time, the provision of the pressing section c22 can enhance the connection tightness of the protruding structure 23 and the recessed structure 11c, enhancing the connection stability of the knob portion 11b and the mating portion 20 b.

Further to the embodiment, the groove width of the lead-in section c21 and the groove width of the working section c23 are equal everywhere.

The groove width of the introduction section c21 is the distance between the opposite inner walls of the introduction section c21 in the set axial direction X, and the groove width of the working section c23 is the distance between the opposite inner walls of the working section c23 in the set axial direction X. The groove widths of the introduction section c21 are equal everywhere, that is, the groove widths of the introduction section c21 are equal everywhere in the extending direction of the guide groove c 2. The groove width of the working section c23 is equal everywhere, i.e., the groove width of the working section c23 is equal everywhere in the extending direction of the guide groove c 2.

When the equal groove widths of the leading-in section c21 and the working section c23 are set, the convex structure 23 moves smoothly in the leading-in section c21 and the working section c23, and the user operation is more labor-saving.

In particular, referring to fig. 6, the guide groove c2 has a guide surface y and a pressing surface j disposed opposite to each other in the set axial direction X, the protrusion 23 moves along the guide surface y, the pressing surface j is disposed perpendicular to the set axial direction X, the guide surface y has a first plane section y1 and a second plane section y2 parallel to the pressing surface j, and a slope section y3 disposed obliquely to the pressing surface j and located between the first plane section y1 and the second plane section y 2. At this time, the first flat surface section y1 and the pressing surface j surround the introduction section c21 of the guide groove c2, the second flat surface section y2 and the pressing surface j surround the working section c23 of the guide groove c2, and the inclined surface section y3 and the pressing surface j surround the pressing section c22 of the guide groove c 2. Of course, the specific configuration of the guide groove c2 is not limited to the above-described manner.

In some embodiments, referring to fig. 2 and 7, the protruding structure 23 includes a first protruding portion 23a and a second protruding portion 23b connected at an angle, the first protruding portion 23a is movably limited in the open groove c1 around the set axial direction X, and the second protruding portion can move along the guiding groove c 2.

The first protruding portion 23a and the second protruding portion 23b may be connected to each other in a split manner, or may be integrally formed, and are not limited. When the protruding structure 23 is inserted into the recessed structure 11c, the first protruding portion 23a and the second protruding portion 23b are both located in the open groove c1, and when the abutting rotation, the first protruding portion 23a moves in the open groove c1, and the second protruding portion 23b moves in the guide groove c 2.

In the circumferential direction around the set axial direction X, the open groove c1 has opposite first and second inner surfaces, with the second inner surface being located between the first inner surfaces.

The matching surface m1 and the abutting surface m2 are oppositely arranged in the set axial direction X, an outlet a1 of the liquid storage cavity penetrates through the matching surface m1, and an inlet a2 of the atomization channel penetrates through the abutting surface m2. The leakage preventing member 14 has a ring-shaped structure (such as a ring, a square ring, etc.), and the leakage preventing member 14 may be a member capable of sealing such as a silicone member or a rubber member.

The leakage preventing member 14 is provided on the knob portion 11b and at least partially protrudes out of the abutment surface m2, and the inlet a2 of the atomizing passage is surrounded by the leakage preventing member 14.

In a possible manner, when the knob portion 11b is rotated from the first position to the second position, no positional displacement occurs in the set axial direction X, and the leakage preventing member 14 can be considered to be compressed at the beginning of insertion of the knob portion 11b into the mating portion 20 b.

In an embodiment, when the knob portion 11b rotates from the first position to the second position, the position moves in the set axial direction X, and the portion of the leakage preventing member 14 protruding out of the abutting surface m2 is gradually compressed during the abutting rotation, so that the compression of the leakage preventing member 14 can be achieved along with the rotation of the knob portion 11b, which is more labor-saving. Further, the compression amount of the leakage preventing member 14 corresponds to the set stroke amount of the knob portion 11b in the set axial direction X, and at this time, the compression amount of the leakage preventing member 14 is large, and the sealing performance is good.
