[0034] Please refer to Figure 3 andFigure 4 Now, the atomizing device 100 provided by the embodiments of the present application will be described. The atomizing device 100 includes a liquid storage chamber 10, an atomizing element 30, and a fog guiding tube 20.

[0035] The liquid storage chamber 10 has an inner cavity 11, and the inner cavity 11 is adapted to store the atomizing liquid 70. At least a part of the atomizing element 30 is arranged in the liquid storage chamber 10 and is adapted to atomize the atomizing liquid 70 to form a mist.

[0036] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the liquid storage chamber 10 is a thin-walled hollow structure, and an inner cavity 11 is formed inside the liquid storage chamber 10. The atomizing liquid 70 such as aromatherapy essential oil can be stored in the inner cavity 11. The atomizing element 30 can be an ultrasonic atomizer or an electric heating atomizer. At least a part of the atomizing element 30 is communicated with the inner cavity 11 and contacts the atomizing liquid 70 in the inner cavity 11, so as to atomize the atomizing liquid 70 in the inner cavity 11 into a mist by ultrasonic vibration or heating.

[0037] The fog guiding tube 20 extends along the z direction in the figure, and the z direction in the figure is the vertical up and down direction. The fog guiding tube 20 communicates the inside and outside of the liquid storage chamber 10, and one end of the fog guiding tube 20 extends into the liquid storage chamber 10. The atomizing element 30 is arranged on one side in the radial direction of the fog guiding tube 20. An opening 21 is provided on the tube wall of the fog guiding tube 20 close to the atomizing element 30 for the mist generated by the atomizing element 30 to be discharged through the fog guiding tube 20.

[0038] Specifically, as Figure 3 and Figure 4 shown, one end of the fog guiding tube 20 is connected to the outer wall of the liquid storage chamber 10 and connects the inside of the fog guiding tube 20 and the outside of the liquid storage chamber 10. The other end of the fog guiding tube 20 extends into the inner cavity 11 and communicates the inside of the fog guiding tube 20 and the inner cavity 11 to connect the outside of the liquid storage chamber 10 and the inner cavity 11 through the fog guiding tube 20.

[0039] The atomizing element 30 is arranged on one side of the fog guiding tube 20 in the x direction. Thus, when the atomizing element 30 atomizes the atomizing liquid 70 to form a mist, the mist condenses on one side of the fog guiding tube 20 facing the atomizing element 30 in the x direction. An opening 21 is provided on the tube wall of the fog guiding tube 20 facing the atomizing element 30 in the x direction to communicate the inside of the fog guiding tube 20 and the inner cavity 11, so that the mist condensed on one side of the fog guiding tube 20 facing the atomizing element 30 in the x direction can timely enter the fog guiding tube 20 through the opening 21 to avoid the mist from escaping into the inner cavity 11.

[0040] The beneficial effects of the atomizing device 100 provided by the present application are as follows: Compared with the prior art, on the side of the guiding fog tube 20 facing the atomizing element 30 of the atomizing device 100 of the present application, there is an opening 21 for the mist generated by the atomizing element 30 to enter the guiding fog tube 20 from the opening 21 and be discharged from the liquid storage chamber 10, reducing the path length of the mist flowing from the atomizing element 30 into the guiding fog tube 20. On the one hand, the concentration of the mist discharged from the guiding fog tube 20 is increased, improving the user experience. On the other hand, the retention of the mist in the inner cavity 11 is reduced, improving the atomization efficiency.

[0041] In some embodiments provided by the present application, as Figure 3 and Figure 4 shown, the end of the guiding fog tube 20 extends into the atomizing liquid 70, and at least part of the opening 21 is above the liquid surface 71 of the atomizing liquid 70.

[0042] Specifically, in the figure, the z direction is the vertical up and down direction. The atomizing liquid 70 accumulates on the lower side in the inner cavity 11 under the action of gravity. One end of the guiding fog tube 20 extending into the inner cavity 11 extends along the z direction in the figure to below the liquid surface 71 of the atomizing liquid 70, and the upper end of the opening 21 is on the upper side of the liquid surface 71 of the atomizing liquid 70 to connect the inner side of the guiding fog tube 20 and the space above the liquid surface 71 of the atomizing liquid 70. The mist generated by atomizing the atomizing liquid 70 by the atomizing element 30 floats to the upper side of the liquid surface 71 of the atomizing liquid 70. The upper end of the opening 21 being on the upper side of the liquid surface 71 of the atomizing liquid 70 enables the mist to enter the guiding fog tube 20 through the opening 21 and be discharged from the atomizing device 100 after floating to the upper side of the liquid surface 71 of the atomizing liquid 70.

[0043] Thus, during the process of the atomizing element 30 atomizing the atomizing liquid 70 into mist, the liquid surface 71 of the atomizing liquid 70 gradually descends, so that the part of the opening 21 for the mist to pass through is always above the liquid surface 71 of the atomizing liquid 70, facilitating the collection of the mist floating from the atomizing liquid 70 to the liquid surface 71.

[0044] In some embodiments provided by the present application, as Figure 3 shown, the opening 21 extends along the length direction of the guiding fog tube 20 to the end of the guiding fog tube 20.

[0045] Specifically, the opening 21 is connected to the lower end of the guiding fog tube 20, so that the area of the opening 21 gradually becomes larger in the direction from top to bottom until the opening 21 is connected to the pipe orifice of the guiding fog tube 20. During the process of the atomizing element 30 atomizing the atomizing liquid 70 into mist, the liquid surface 71 of the atomizing liquid 70 gradually descends, so that the flow-through area of the opening 21 located above the liquid surface 71 of the atomizing liquid 70 gradually increases, making it easier for the mist to enter the guiding fog tube 20 through the opening 21.

[0046] Thus, by connecting the lower end of the opening 21 to the pipe orifice at one end of the fog guide pipe 20 extending into the inner cavity 11, the flow efficiency of the fog at the opening 21 is increased, thereby increasing the concentration of the fog entering the fog guide pipe 20. Furthermore, the atomizing device 100 of the embodiment of the present application has the advantage of a relatively high fog output volume.

[0047] In some embodiments provided by the present application, as Figure 3 shown, the dimension of the opening 21 in the circumferential direction of the fog guide pipe 20 gradually increases in the direction close to the end of the fog guide pipe 20.

[0048] Specifically, during the process of the atomizing element 30 atomizing the atomizing liquid 70 into fog, the liquid level 71 of the atomizing liquid 70 gradually drops, increasing the gas volume in the inner cavity 11, thereby increasing the probability of the fog staying in the inner cavity 11. The circumferential direction of the fog guide pipe 20 is as Figure 3 shown by the a direction in the figure. The dimension of the opening 21 in the circumferential direction of the fog guide pipe 20 gradually increases from top to bottom, so that the flow area of the fog at the opening 21 gradually increases during the process of the atomizing element 30 atomizing the atomizing liquid 70 into fog, making it easier for the fog to enter the fog guide pipe 20 and be discharged from the inner cavity 11, reducing the probability of the fog staying in the inner cavity 11. Thus, the concentration of the fog entering the fog guide pipe 20 is increased, and furthermore, the atomizing device 100 of the embodiment of the present application has the advantage of a relatively high fog output volume.

[0049] In some embodiments provided by the present application, as Figure 3 and Figure 4 shown, a baffle 12 is provided in the liquid storage chamber 10. The baffle 12 is located on the side of the fog guide pipe 20 facing the atomizing element 30, and the opening 21 is located between the baffle 12 and the atomizing element 30.

[0050] Specifically, the baffle 12 is located in the inner cavity 11. The baffle 12 and the atomizing element 30 are both provided on the same side of the fog guide pipe 20, and the baffle 12 and the atomizing element 30 are arranged at intervals along the axial direction of the fog guide pipe 20 and are provided above the opening 21. Moreover, the baffle 12 has an angle with the z direction in the figure, so that the fog generated by the atomizing element 30 accumulates at the opening 21 and flows towards the fog guide pipe 20 during the upward floating process.

[0051] Thus, during the process of the fog generated by the atomizing element 30 floating up to the inner cavity 11, the baffle 12 can accumulate the fog at the opening 21, increasing the fog concentration at the opening 21, thereby increasing the fog concentration entering the fog guide pipe 20. Furthermore, the atomizing device 100 of the embodiment of the present application has the advantage of a relatively high fog output volume.

[0052] In some embodiments provided by the present application, as Figure 3 and Figure 4 shown, the baffle 12 is provided with a concave portion 121, and the opening of the concave portion 121 faces the atomizing element 30.

[0053] Specifically, the concave portion 121 is provided on the surface of the baffle 12 facing the atomization component side, and the opening of the concave portion 121 faces the atomization element 30, that is, the inner diameter dimension of the concave portion 121 in the x direction along the figure gradually increases in the direction towards the atomization element 30. Figure 4 Thus, during the process that the mist generated by the atomization element 30 floats up to the inner cavity 11, the mist will temporarily gather in the concave portion 121, further increasing the mist concentration at the opening 21, avoiding the mist from escaping along the surface of the baffle 12 and staying at the top of the inner cavity 11, and increasing the probability that the mist generated by the atomization element 30 enters the fog guide tube 20 through the opening 21, so that the atomization device 100 of the embodiment of the present application has the advantages of higher atomization efficiency and higher fog output.

[0054] In some embodiments provided by the present application, as

[0055] shown in Figure 3 and Figure 4 the atomization element 30 is provided with an atomization channel 31. One end of the atomization channel 31 communicates with the inner cavity 11, and the other end of the atomization channel 31 communicates with the outside of the liquid storage chamber 10. An ultrasonic atomization sheet 32 is provided in the atomization channel 31, and the atomization liquid 70 is filled on the side of the ultrasonic atomization sheet 32 facing the inner cavity 11.

[0056] Specifically, the atomization element 30 is an ultrasonic atomizer. The atomization element 30 is provided at the bottom of the liquid storage chamber 10 along the z direction in the figure, and there is a set interval between the atomization element 30 and the fog guide tube 20 along the z direction in the figure. The atomization channel 31 in the atomization element 30 penetrates the inner wall and the outer wall of the liquid storage chamber 10. An ultrasonic atomization sheet 32 is provided in the atomization channel 31. The ultrasonic atomization sheet 32 extends radially along the atomization channel 31. The ultrasonic atomization sheet 32 vibrates at a set frequency to atomize the atomization liquid 70 in contact with it into fine liquid beads, and conducts the air at the end of the ultrasonic atomization sheet 32 far from the atomization liquid 70 to the side of the ultrasonic atomization sheet 32 facing the atomization liquid 70 to form mist.

[0057] Thus, the ultrasonic atomizer can be continuously immersed in the atomization liquid 70 and atomize the atomization liquid 70 into mist in the atomization liquid 70. The density of the mist generated by the atomization element 30 is small and can float up to the upper side of the liquid surface 71 of the atomization liquid 70 and enter the fog guide tube 20 through the opening 21 and be discharged. Moreover, the position where the mist passes through the liquid surface 71 of the atomization liquid 70 is always directly above the atomization unit and has a fixed distance from the fog guide tube 20. Therefore, the concentration of the smoke entering the fog guide tube 20 remains balanced during the change of the liquid surface 71 of the atomization liquid 70, so that the atomization unit provided by the present application has the advantages of high fog output and uniform fog output while having a high fog output.

[0058] In some embodiments provided by the present application, as Figure 3 andFigure 4 As shown in the figure, the atomizing device 100 further includes a gas supply element 40. The gas supply element 40 is arranged on the side of the atomizing channel 31 away from the liquid storage chamber 10, so as to be adapted to supply gas to the side of the ultrasonic atomizing sheet 32 away from the inner cavity 11.

[0059] Specifically, the gas supply element 40 can be a device such as a fan or an air compressor. The gas supply element 40 can supply gas to the side of the atomizing channel 31 away from the liquid storage chamber 10, so as to increase the gas flow rate entering the inner cavity 11 when the ultrasonic atomizing sheet 32 is working by increasing the air pressure on the side of the ultrasonic atomizing sheet 32 away from the atomizing liquid 70.

[0060] Thus, on the one hand, the concentration of the mist generated by the ultrasonic atomizing sheet 32 is increased, and then the concentration of the mist entering the mist guide tube 20 is increased, so that the atomizing device 100 of the embodiment of the present application has the advantage of a higher mist output. On the other hand, the air pressure in the inner cavity 11 is increased, so as to increase the gas flow rate entering the mist guide tube 20 through the opening 21, and further improve the mist output of the atomizing device 100.

[0061] In some embodiments provided by the present application, as Figure 1 , Figure 3 and Figure 4 shown, the atomizing device 100 further includes a bottom case 50. The bottom case 50 is connected to the liquid storage chamber 10. A bottom cavity 51 is formed in the bottom case 50. One end of the atomizing channel 31 away from the liquid storage chamber 10 extends into the bottom cavity 51 and communicates with the bottom cavity 51. The gas supply element 40 is arranged in the bottom case 50 so as to be adapted to supply gas into the bottom cavity 51.

[0062] Specifically, the bottom case 50 is arranged on the side of the liquid storage chamber 10 facing the z direction in the figure. The bottom case 50 is connected to the liquid storage chamber 10, and an open mouth is provided on the side of the bottom case 50 facing the liquid storage chamber 10. The outer wall of a part of the liquid storage chamber 10 and the inner wall of the bottom case 50 surround to form the bottom cavity 51. One end of the atomizing channel 31 communicates with the inner cavity 11, and the other end of the atomizing channel 31 communicates with the bottom cavity 51.

[0063] The gas supply element 40 is arranged in the bottom case 50 and is adapted to supply gas into the bottom case 50, so as to increase the air pressure in the bottom case 50, that is, the air pressure on the side of the ultrasonic atomizing sheet 32 away from the inner cavity 11.

[0064] Thus, the gas supply element 40 supplies gas into the bottom case 50 to increase the air pressure on the side of the ultrasonic atomizing sheet 32 away from the inner cavity 11. On the one hand, gas leakage can be effectively avoided, and the air pressure on the side of the ultrasonic atomizing sheet 32 away from the inner cavity 11 can be further increased. On the other hand, when the gas supply element 40 is started or closed, the space in the bottom cavity 51 can be used to buffer the air pressure, so as to avoid a drastic change in the air pressure on the side of the ultrasonic atomizing sheet 32 away from the inner cavity 11.

[0065] In some embodiments provided by the present application, the atomization device 100 further includes a circuit board 60 disposed in the bottom cavity 51, and the circuit board 60 extends along the airflow direction generated by the air supply element 40.

[0066] Specifically, the airflow generated by the air supply element 40 extends along the z direction in the figure, and the circuit board 60 also generally extends along the z direction in the figure, enabling the airflow generated by the air supply element 40 to perform convective heat transfer on the circuit board 60.

[0067] Thus, when the air supply element 40 supplies air into the bottom cavity 51, the airflow generated by the air supply element 40 flows along the surface of the circuit board 60 to dissipate heat from the circuit board 60, and the fact that the circuit board 60 generally extends along the z direction in the figure can increase the contact area between the airflow generated by the air supply element 40 and the circuit board 60, thereby improving the cooling efficiency of the air supply element 40 for the circuit board 60.

[0068] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
