[0032] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0033] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 14 As shown, a humidifier provided in this embodiment includes a shell, an atomization device (not shown), a blower 20 and an aromatherapy box 30, the shell having a water storage chamber 151, an atomization groove 124, an air inlet channel and a mist outlet channel 105, the water outlet of the water storage chamber 151 is connected to the atomization groove 124, the atomization sheet of the atomization device is arranged in the atomization groove 124, the mist outlet channel 105 has a mist inlet 1321 and an air inlet 1323, and the mist inlet 1321 of the mist outlet channel 105 corresponds to the atomization groove 124.

[0035] The blower 20 and the aromatherapy box 30 are both arranged on the air inlet channel, and the air outlet of the air inlet channel is connected to the air inlet 1323 of the mist outlet channel. Specifically, in the present embodiment, the air inlet channel has two sections, namely, the air inlet front section 101 and the air inlet rear section. The aromatherapy box 20 is arranged in front of the air inlet front section 101, and the blower 20 is arranged between the air inlet front section 101 and the air inlet rear section to drive the air flow through the aromatherapy box 20, the air inlet front section 101 and the air inlet rear section in sequence to the mist outlet channel 105. Of course, in other embodiments, the setting positions of the air inlet channel, the blower 20 and the aromatherapy box 30 are not limited thereto, and the blower 20 and the aromatherapy box 30 may be both arranged at the front end position of the air inlet channel, or the aromatherapy box 30 may be arranged between the air inlet front section 101 and the blower 20, and so on.

[0036] The air intake passage also has a buffer section, specifically, the buffer section is located on the air intake rear section of the air intake passage. The buffer section at least includes an air intake deceleration tube 102, the air intake deceleration tube 102 has a lateral breach 1021 for air outlet and an arc-shaped guide wall 1022 for guiding the airflow in the tube body to the lateral breach 1021.

[0037] When working, the blower 20 drives the airflow to flow in the air inlet channel to achieve air intake. In the process, the volatilized aroma gas in the aroma box 30 is brought in; when passing through the air inlet deceleration tube 1021, the airflow in the air inlet deceleration tube 1021 is blown out from the side breach 1021 under the guidance of the arc-shaped guide wall 1022, which can effectively decelerate the airflow and has a simple structure; the decelerated airflow enters the mist outlet channel 105 through the air inlet 1323 of the mist outlet channel 105, and can be fully mixed with the mist for a long time, so that the aroma effect is better. At the same time, the deceleration buffer airflow can effectively reduce noise and vibration; the stability is better, and the user experience effect is effectively improved.

[0038] More specifically, in order to further decelerate and guide the airflow, in this embodiment, the buffer section further includes a lateral breach 1021 connected to the intake deceleration pipe 102 and a reflux section 103 extending in a direction opposite to the intake deceleration pipe 102. The airflow forms a return transmission on the intake deceleration pipe 102 and the reflux section 103, and the deceleration effect is better.

[0039] The buffer section further includes a transition section 104, through which the reflux section 103 and the air inlet 1323 of the mist outlet channel 105 are connected to each other, so as to guide the airflow to the mist outlet channel 105; further, the air inlet 1323 of the mist outlet channel 105 is away from the outlet of the reflux section 103 (such as Figure 5 As shown in FIG. 1 , the transition section 104 passes through the side end of the mist outlet channel 105 and goes around to the side of the air inlet 1323 corresponding to the mist outlet channel 105 to connect with the air inlet 1323 of the mist outlet channel 105. In this way, the airflow flowing out of the reflux section 103 will be guided and buffered by the transition section 104 and then enter the mist outlet channel 105 in the reverse direction, and the airflow will be decelerated and buffered again.

[0040] More specifically, in this embodiment, the intake deceleration tube 102 extends upward, the reflow section 103 extends downward, and the transition section 104 extends horizontally; by the intake deceleration tube 102 and the reflow section 103 reflowing up and down, the channel for deceleration and buffering can be extended within a limited space, and the structure is more compact. At the same time, the setting of the transition section 104, on the one hand, plays the role of transition connection, and on the other hand, can also make the airflow turn back and decelerate again in the horizontal direction, so that the airflow can achieve the best deceleration and buffering within a limited space. Of course, in other embodiments, the buffer structure of the buffer section is not limited to this, and the deceleration at the rear end of the intake deceleration tube 102 is replaced by other structures, such as multiple bent S-shaped sections, etc.; or, when the intake deceleration tube 102 can achieve good deceleration, the deceleration structure of the intake deceleration tube 102 can also be set separately.

[0041] Specifically, in order to realize the above-mentioned buffer section, the present embodiment provides a more preferred structural layout; the shell includes an outer shell 11, an inner shell 12, an air inlet cover 13, an aerosol mixing chamber 14 and a water tank 15, and the inner shell 12 is arranged in the outer shell 11, so that an isolation space 100 is formed between the inner shell 12 and the outer shell 11, and the blower 20, the aromatherapy box 30 and other components for realizing humidification and atomization (such as circuit boards, sensors, etc.) are all arranged in the isolation space 100.

[0042] The atomization groove 124 is formed in the inner shell 12, and the intake deceleration tube 102 is formed by an integral protrusion extending from the inner shell 12. Specifically, the air outlet of the blower 20 is directly connected to the bottom port of the intake deceleration tube 102, and the lateral breach 1021 and the arc-shaped guide wall 1022 are formed at the top position. The air intake hood 13 is arranged in the inner shell 12, and has a cover 131 covering the air intake deceleration tube 102 and a hollow cylinder section 132 located above the atomization groove 124. The remaining space in the cover 131 (i.e., half of the space remaining after covering the air intake deceleration tube 102) forms the reflux section 103. The lower end opening of the hollow cylinder section 132 corresponds to the atomization groove 124 to serve as a mist inlet 1321 of the mist outlet channel 105. The hollow cylinder section 132 is provided with a lateral opening at the side end away from the cover 131, and the lateral opening serves as an air inlet 1323 of the mist outlet channel 105. The bottom of the air intake hood 13 is also recessed upward to have a concave cavity 133 connecting the cover 131 and the lateral opening of the hollow cylinder section 132, and the concave cavity 133 is the transition section 104. By adopting the cooperation of the inner shell 12 and the air intake cover 13, all the structures of the buffer section are realized at the same time, the structural cooperation is simple and the design is ingenious.

[0043] More specifically, the aerosol mixing chamber cover 14 is on the air inlet cover 13, and is formed with an aerosol mixing tube 141 connected to the upper end opening 1322 of the hollow cylinder section 132. The spliced ​​hollow cylinder section 132 and the aerosol mixing tube 141 together form the aerosol outlet channel 105. The water mist and the airflow carrying the volatile gas of the essential oil enter the aerosol outlet channel 105 through the lower end opening (i.e., the mist inlet 1321) and the side opening (i.e., the air inlet 1323) of the hollow cylinder section 132, respectively, and are fully mixed at the position of the aerosol mixing tube 141; the structure is simple and easy to implement. A mist outlet nozzle 142 is also provided at the top of the aerosol mixing tube 141 to control the amount of mist or the direction of mist outlet, etc.

[0044] The water tank 15 is assembled in the inner shell 12, and the inner cavity of the water tank 15 is the water storage chamber 151. The inner shell 12 is also formed with a water inlet 121 for connecting the water tank 15, a water outlet 122 connecting the water inlet 121, and a connecting groove 123 connecting the water outlet 122 and the atomizing groove 124. Specifically, a filter element (not shown) is provided on the water tank 15 to play the role of filtering and water outlet. The water inlet 121 on the inner shell 12 is connected to the filter element, and the water in the water tank 15 flows into the water inlet 121 of the inner shell 12 after being filtered by the filter element; more specifically, the water inlet 121 and the water outlet 122 of the inner shell 12 are connected by a water pipe. A heating plate 1231 is provided on the connecting groove 123 for heating the atomized water. Of course, the opening of the heating plate 1231 can be selected by the user.

[0045] Thus, the structure of the outer shell 11, the inner shell 12, the air inlet cover 13, the aerosol mixing chamber 14 and the water tank 15 constitutes a complete shell structure of the present invention, and the various parts are detachably connected to facilitate cleaning, maintenance and replacement. Of course, in other embodiments, the structure of the shell is not limited to this, and other structures can also be used instead.

[0046] Furthermore, a mounting frame 40 is provided on the air inlet passage, and a receiving cavity 41 for inserting the aromatherapy box 30 and a through hole 42 connecting the receiving cavity 41 and the air inlet passage are provided on the mounting frame 40. The aromatherapy box 30 is detachably inserted into the receiving cavity 41 of the mounting frame 40 to realize the assembly of the aromatherapy box 30, so that the aroma gas volatilized by the essential oil in the aromatherapy box 30 can flow into the air inlet passage.

[0047] Specifically, the aromatherapy box 30 includes a box body 31 and filter cotton 33. The box body 31 has an essential oil receiving tank 311, a double-layer plywood 312 located outside the essential oil receiving tank 311, and an air inlet grille 313 located outside the double-layer plywood 312. The air inlet grille 313 plays an isolation and protection role. The double-layer plywood 312 is provided with a vent for ventilation. The filter cotton 33 is arranged in the double-layer plywood 312. When the blower 20 is running, the external air enters from the air inlet grille 313, enters the essential oil receiving tank 311 after being filtered by the filter cotton 33, mixes with the volatilized aroma gas in the essential oil receiving tank 311, and then enters the air inlet channel from the through hole 42 of the mounting frame 40. The structural design is simple and the essential oil volatilization effect is good.

[0048] More specifically, an essential oil adsorption pad 32 is provided in the essential oil containing groove 311 of the aromatherapy box 30. When the essential oil is dripped onto the essential oil adsorption pad 32, the essential oil can be better adsorbed and the essential oil can be better helped to volatilize.

[0049] More specifically, a clearance opening is provided at the bottom of the housing 11 for the installation and removal of the aromatherapy box 30 . Thus, when adding essential oil, the aromatherapy box 30 can be directly taken out, which makes the operation more convenient.

[0050] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
