The hook is located at the sliding groove 611, and the end of the pull rod 641 away from the hook 642 is fixed to the outer sleeve 61. When the inner sleeve 62 slides to the bottom of the outer sleeve 61, the locking groove 622 is locked by the hook 642 to lock the inner sleeve 62 in the outer sleeve 61. The atomization device following with the inner sleeve 62 slides to the inside of the outer sleeve 61 along the outer sleeve 61 axial direction, so that the atomization device is built in and hidden in housing 1 for use. When the atomization device needs to be repaired or replaced, the hook 642 only needs to be released from the locking groove 622 and the inner sleeve 62 is unlocked, the spring 63 (upward) elastically pushes the inner portion by the spring 63. The inner sleeve 62 is elastically pushed from the bottom of the outer sleeve 61 toward the top of the outer sleeve 61, so that the atomization device following with the inner sleeve 62 slides to the outside of the outer sleeve 61 along the outer sleeve 61 axial direction, and then the accommodation slot is ejected. So that atomization device could be easily removed from the accommodation slot for maintenance and replacement of the atomization device.

According to an embodiment, referring to FIGS. 4, 8, and 9, as a specific implementation of the aromatherapy machine for air purification provided in the present application, a slider 621 is provided with a limiting groove 623, configured for guiding the hook 642 to move in or out of the of the locking groove 622, the locking groove 622 is located inside the limiting groove 623.

In this embodiment, a slider 621 is provided with a limiting groove 623, configured for guiding the hook 642 to move in or out of the locking groove 622, the locking groove 622 is located inside the limiting groove 623. The movement path of the hook 642 is guided by the limiting groove 623, so that the hook 642 can smoothly move in or out of the locking groove 622, and the inner sleeve 62 can be locked or unlocked and the smoothness and stability of the hook 642 to be moved in or out of the locking groove 622 could be enhanced, which facilitates the installation and detachment of the atomization device.

According to an embodiment, referring to FIGS. 4, 8, and 9, as a specific implementation of the aromatherapy machine for air purification provided in the present application, the limiting groove 623 is provided with a limiting spring arm 65 configured for stopping the hook 642 and defining the movement path of the hook 642 in the limiting groove 623.

In this embodiment, a limiting spring arm 65 is arranged in the limiting groove 623, and the hook 642 can be stopped by the limiting spring arm 65 to limit the movement path of the hook 642 in the limiting groove 623, thereby further making the hook 642 capable of moving in or out of the locking groove 622 quickly and smoothly, to achieve the locking or unlocking of the inner sleeve 62 and to enhance the smoothness and stability of the hook 642 moving in or out of the locking groove 622, thus facilitating the installation and detachment of the atomization device.

According to an embodiment, referring to FIGS. 4, 8, and 9, as a specific implementation of the aromatherapy machine for air purification provided in the present application, an inner wall of the limiting groove 623 is convex to form a limiting block 66 for stopping the hook 642 and defining a movement path of the hook 642, and the position of the limiting block 66 correspond to the opening position of the locking groove 622.

In this embodiment, a limiting block 66 is protruded on the inner side wall of the limiting groove 623, and when the hook 642 moves out of the locking groove 622, the limiting block 66 is used to stop hook 642 coordinately, the movement path of the hook 642 is limited, so that the hook 642 can move out of the lock groove 622 quickly and stably, and the inner sleeve 62 can be quickly unlocked. The efficiency of the installation and detachment of the atomization device can be improved, and the stability of installation and detachment of the atomization device can be enhanced.

According to an embodiment, referring to FIG. 7, as a specific implementation of the aromatherapy machine for air purification provided in the present application, the slider 621 is provided with a slot 624 for inserting the top end of the spring 63, and the slot 624 extends along an axial direction of the inner sleeve 62, and a bottom end of the spring 63 is connected to the inner bottom surface of the outer sleeve 61.

In this embodiment, the slider 621 is provided with a slot 624 for inserting the top end of the spring 63, and the slot 624 extends along the axial direction of the inner sleeve 62, and the top end of the spring 63 is arranged in the slot 624. The bottom end of the spring 63 is connected to the inner bottom surface of the outer sleeve 61, so that the spring 63 is defined by the slot 624, which enhances the stability of the spring 63 to push the inner sleeve 62 elastically.

The above description is only the preferred embodiments of this application, and is not intended to limit this application. Any modification, equivalent replacement, and improvement made within the spirit and principle of this application shall be included in the protection range of this application.
