DETAILED DESCRIPTION

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0034] This embodiment relates to an atomization assembly, referring to Figure 1-Figure 5 , including a main shell 100, a front module 200 and an atomizing module 300. Among them, a liquid storage tank 110 for storing a liquid matrix is ​​arranged inside the main shell 100; the front module 200 can be reciprocated and assembled on the main shell 100 and the front module 200 is provided with a mist outlet 230; the atomizing module 300 is placed between the main shell 100 and the front module 200, the liquid guide surface 300a of the atomizing module 300 is connected to the liquid storage tank 110, and the atomizing surface 300b of the atomizing module 300 is connected to the mist outlet 230.

[0035] The operation of removing the atomizer module 300 is as follows: move the front module 200 to the side away from the main shell 100. At this time, the distance between the main shell 100 and the front module 200 increases, and the atomizer module 300 is loosened. At this time, the atomizer module 300 can be removed from between the front module 200 and the main shell 100 without disassembling other parts. The operation is simple and convenient.

[0036] The operation of replacing the atomizer module 300 is as follows: insert the atomizer module 300 between the front module 200 and the main shell 100, and then move the front module 200 to the side close to the main shell 100. At this time, the distance between the main shell 100 and the front module 200 is reduced, and the atomizer module 300 is clamped between the main shell 100 and the front module 200, completing the replacement of the atomizer module 300. This process also does not require the removal of other parts, and the operation is simple and convenient.

[0037] In some embodiments, the front module 200 can achieve reciprocating movement by spiral rotation. If the atomizer module 300 is to be removed, the front module 200 is spirally rotated toward one end away from the main shell 100. At this time, the distance between the main shell 100 and the front module 200 increases, and the atomizer module 300 is loosened. At this time, the atomizer module 300 can be removed from between the front module 200 and the main shell 100; if the atomizer module 300 is to be replaced, the atomizer module 300 is placed between the front module 200 and the main shell 100, and then the front module 200 is spirally rotated toward one end close to the main shell 100. At this time, the distance between the main shell 100 and the front module 200 is reduced, and the atomizer module 300 is clamped between the main shell 100 and the front module 200, and the atomizer module 300 is replaced. In the process of removing and replacing the atomizer module 300, there is no need to disassemble other parts, and only the front module 200 needs to be rotated to change the distance between the front module 200 and the main shell 100, which is easy to operate. In other embodiments, the front module 200 can also be configured to be retractable relative to the main housing 100. When the front module 200 is pulled outward, the distance between the main housing 100 and the front module 200 increases, and when the front module 200 is pushed back inward, the distance between the main housing 100 and the front module 200 decreases. Furthermore, a locking and positioning structure is also provided between the main housing 100 and the front module 200, so that the front module 200 can be positioned at a set position relative to the main housing 100.

[0038] In order to better accommodate the atomization module 300 in the atomization assembly, a module cavity 120 for placing the atomization module 300 is provided between the main shell 100 and the front module 200; and in order to be able to take out and put in the atomization module 300, the main shell 100 and / or the front module 200 are provided with a channel 130 connecting the module cavity 120.

[0039] In this embodiment, refer to Figure 5 , the module cavity 120 is arranged on the main shell 100, and the channel 130 is also located on the main shell 100. Specifically, the channel 130 is opened at the lower end of the main shell 100, and it is also convenient to take out the atomization module 300 from the lower end. In other embodiments, the channel 130 can also be opened at other positions of the main shell 100; when the module cavity 120 is arranged on the front module 200, the channel 130 will also be located on the front module 200. In some embodiments, the module cavity 120 can also be partially arranged on the main shell 100 and partially arranged on the front module 200. At this time, the channel 130 is also partially opened on the main shell 100 and partially opened on the front module 200.

[0040] Reference Figure 2 and Figure 4The atomizing module 300 is provided with a raised handle 350 exposed in the channel 130. By applying force to the raised handle 350, the atomizing module 300 can be taken out more easily. Furthermore, in order to make it easier to apply force to the raised handle 350, the raised handle 350 is provided with a hook facing the main housing 100, and the user can hook the hook to more easily take out the atomizing module 300.

[0041] Reference Figure 1-Figure 3 and Figure 6 and Figure 7 The front module 200 includes a front cover 220 and a movable cover 210. The front cover 220 is fixedly mounted on the main housing 100, and the movable cover 210 passes through the front cover 220 and can move forward or backward relative to the front cover 220, thereby changing the distance between the movable cover 210 and the main housing 100.

[0042] A contact surface 213 for abutting the atomizer module 300 is provided on the side of the movable cover 210 facing the atomizer module 300. When the movable cover 210 moves away from the main shell 100, the distance between the main shell 100 and the contact surface 213 of the movable cover 210 increases, and the atomizer module 300 is loosened to facilitate the removal of the atomizer module 300; when the movable cover 210 moves close to the main shell 100, the distance between the main shell 100 and the contact surface 213 of the movable cover 210 decreases, and the atomizer module 300 is clamped between the contact surface 213 of the main shell 100 and the movable cover 210, completing the installation of the atomizer module 300. At this time, the atomizer module 300 is also not easy to be removed.

[0043] In this embodiment, refer to Figure 6-Figure 7 , a first arc segment 211 protruding outward is provided on the outer peripheral wall of the movable cover 210, and a second arc segment 221 protruding inward and having a length greater than the first arc segment 211 is provided on the inner wall of the front cover 220; the first arc segment 211 can rotate on the second arc segment 221, thereby realizing that the movable cover 210 can rotate in the front cover 220. In this embodiment, a surface of the first arc segment 211 facing away from the main shell 100 contacts a surface of the second arc segment 221 facing the main shell 100, and if the movable cover 210 moves toward an end away from the main shell 100, the first arc segment 211 of the movable cover 210 will hit the second arc segment 221 of the front cover 220, thereby limiting the movable cover 210 from being separated from the front cover 220 from the end away from the main shell 100.

[0044] In order to achieve an adjustable distance between the movable cover 210 and the main shell 100, the first arc segment 211 is flat on the side facing away from the main shell 100, and the second arc segment 221 has a side facing the main shell 100 having: a plane corresponding to the first arc segment 211, and a slope 225 inclined toward the side of the main shell 100; the slope 225 is configured to have one side connected to the plane of the first arc segment 211, which side is the lowest point of the slope 225, and the other side inclined toward the side of the main shell 100 is the highest point.

[0045] When the atomizer module 300 is to be locked, the movable cover 210 is rotated toward the inclined surface 225, and the height of the inclined surface 225 gradually squeezes the first arc segment 211 and the corresponding plane thereof. At this time, the movable cover 210 moves toward the main shell 100, and the distance between the movable cover 210 and the main shell 100 gradually decreases. The atomizer module 300 is clamped by the movable cover 210 and the front module 200, and the replacement of the atomizer module 300 is completed without disassembling other components; when the atomizer module 300 is to be removed, the movable cover 210 is rotated in the other direction of the inclined surface 225, and the first arc segment 211 gradually moves away from the inclined surface 225. At this time, the movable cover 210 moves toward the direction away from the main shell 100, and the distance between the movable cover 210 and the main shell 100 gradually increases, and the atomizer module 300 is released. At this time, the atomizer module 300 can be removed from between the front module 200 and the main shell 100 without disassembling other components. The operation is simple, easy to understand, and convenient and fast.

[0046] In this embodiment, in order to make the user know the direction of locking and releasing more clearly, an arrow is provided on the outer surface of the front cover 220, and the direction of the arrow is consistent with the direction of transition from the plane to the inclined surface 225, that is, consistent from the lowest point to the highest point of the inclined surface 225. When the user wants to lock the atomization module 300, he only needs to rotate the movable cover 210 clockwise in the direction of the arrow, and the movable cover 210 moves toward the main shell 100, and the distance between the movable cover 210 and the main shell 100 is reduced to clamp the atomization module 300, and the replacement of the atomization module 300 is completed; when the user wants to remove the atomization module 300, he only needs to rotate the movable cover 210 in the opposite direction of the arrow direction, and the movable cover 210 moves away from the main shell 100, and the distance between the movable cover 210 and the main shell 100 becomes larger to release the atomization module 300, and the user can remove the atomization module 300. The arrow direction setting makes the user more clear about the rotation direction of the movable cover 210 during the process of removing and replacing the atomization module 300. In other embodiments, other markings similar to arrow directionality can also be set on the front cover 220.

[0047] In order to prevent the movable cover 210 from falling off in the direction close to the main housing 100 during the movement, Figure 7A limiting protrusion 222 protruding inward is provided on the inner wall of the front cover 220, and the limiting protrusion 222 cooperates with the second arc segment 221 to sandwich the first arc segment 211 in the middle. In the direction of the mobile cover 210 approaching and moving away from the main shell 100, the movement range of the mobile cover 210 is limited, so as to better protect the atomization module 300 and prevent the mobile cover 210 from falling off. Furthermore, a guiding inclined surface 226225 is provided on the limiting protrusion 222, so as to more conveniently and smoothly pass the mobile cover 210 through the front cover 220, so that the first arc segment 211 smoothly enters between the limiting protrusion 222 and the second arc segment 221, and the mobile cover 210 is sleeved on the front cover 220.

[0048] Reference Figure 6-Figure 7 Two first arc segments 211 are provided on the outer peripheral wall of the movable cover 210, and two second arc segments 221 are provided on the inner wall of the front cover 220; in order to firmly assemble the front cover 220 on the main housing 100, the front cover 220 is provided with two screw pillars 223 for screws to pass through, and the front cover 220 is screwed through the screw pillars 223 to be locked on the main housing 100 to prevent the front cover 220 from rotating when the movable cover 210 is rotated. The two screw pillars 223 separate the two second arc segments 221, and a travel space 214 is provided between the two first arc segments 211 to avoid the travel space of the screw pillars 223, so that the movable cover 210 can be rotated smoothly. The first arc segment 211, the second arc segment 221, the screw support 223 and the travel space 214 for avoiding the screw support 223 also prevent the cover 210 from being excessively moved, thereby avoiding damage to the front cover 220 and the moving cover 210; at the same time, they also have a feedback function, reminding the user not to rotate in the same direction. In other embodiments, the front cover 220 can also be fixed to the main housing 100 by other structures and methods, which are not limited here.

[0049] When the movable cover 210 is rotated, in order to give the user feedback that the movable cover 210 has been rotated to the right position, one of the outer wall of the first arc segment 211 and the inner wall of the front cover 220 is provided with an elastic protrusion 224, and the other is provided with a groove 212 corresponding to the elastic protrusion 224. Figure 6-Figure 7, an elastic protrusion 224 is arranged on the inner wall of the front cover 220, and two grooves 212 corresponding to the elastic protrusion 224 are arranged on the outer wall of the first arc segment 211. When the movable cover 210 rotates to a set position in one direction, the distance between the movable cover 210 and the main shell 100 reaches the set distance, at which time the elastic protrusion 224 is placed in one of the grooves 212, and a specific sound, such as a "click", is emitted, giving feedback to the user, reminding the user that it is not necessary to continue to rotate the movable cover 210 in the same direction at this time, and if the movable cover 210 is continued to be rotated, the atomization module 300 will be damaged at this time; when the movable cover 210 rotates to a set position in another direction, the distance between the movable cover 210 and the main shell 100 reaches the set distance, at which time the elastic protrusion 224 is placed in another groove 212, and a specific sound, such as a "click", is emitted, giving feedback to the user, reminding the user that it is not necessary to continue to rotate the movable cover 210 in the same direction at this time, and the atomization module 300 can be taken out.

[0050] In other embodiments, only one elastic protrusion 224 and one corresponding groove 212 may be provided, so that feedback is provided only when the movable cover 210 rotates to a set position in one direction.

[0051] In other embodiments, the elastic protrusion 224 may also be disposed on the outer wall of the first arc segment 211 , and the groove 212 may be disposed on the inner wall of the front cover 220 .

[0052] refer to Figure 8 In this embodiment, the atomization module 300 includes a first cover 310, a second cover 320 and an atomization sheet 330. The second cover 320 is detachably mounted on the first cover 310; the atomization sheet 330 is installed in the first cover 310 and the second cover 320. In this embodiment, the second cover 320 is detachably mounted on the first cover 310 in that the first cover 310 and the second cover 320 are snap-fitted together, so that the atomization module 300 can be easily disassembled and assembled, and the atomization sheet 330 in the atomization module 300 can be easily and quickly replaced.

[0053] In order to achieve the connection between the entire atomization component and ensure that the liquid matrix in the liquid storage tank 110 of the main shell 100 can be transported to the mist outlet 230 through atomization, one side of the atomization sheet 330 is exposed to the first cover body 310 and connected to the mist outlet 230, and the other side is exposed to the second cover body 320 and can contact the liquid matrix in the liquid storage tank 110. In this way, the liquid matrix in the liquid storage tank 110 is output to the mist outlet 230 through atomization for the patient to inhale, thereby achieving the atomization treatment effect.

[0054] This embodiment also relates to an atomizer (not shown), comprising a main unit (not shown) and an atomizer assembly, wherein the atomizer assembly is assembled on the main unit. The specific structure of the atomizer assembly is as described above.

[0055] The atomizing assembly is also provided with a conductive contact 340 for electrically connecting to the host. In this embodiment, the host further includes a control circuit panel, a battery, and a control switch exposed on the housing of the host. The operation of the entire atomizer is realized through the control of the host, and the liquid matrix in the liquid storage tank 110 is transported to the atomizing module 300, atomized by the atomizing module 300, and then transported to the mist outlet 230 in the front module 200. The patient inhales the atomized liquid matrix to achieve the purpose of treatment.

[0056] The working principle of the utility model is as follows: the liquid matrix used for the treatment of the patient is loaded into the liquid storage tank 110 in the main shell 100, and the main host of the nebulizer controls the liquid matrix to be atomized through the atomization module 300, and then outputs it through the mist outlet 230 in the front module 200 for the patient to inhale, so as to achieve the purpose of treatment; in this process, the disassembly and assembly of the atomization module 300 is achieved by adjusting the distance between the front module 200 and the main shell 100. When the front module 200 moves away from the main shell 100, the distance between the main shell 100 and the front module 200 increases, and the atomization module 300 is loosened to facilitate removal. When the front module 200 moves toward the side close to the main shell 100, the distance between the main shell 100 and the front module 200 decreases, and the atomization module 300 is clamped between the main shell 100 and the front module 200, so as to achieve the locking of the atomization module 300.

[0057] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
