[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "multiple" means two or more.

[0039] Reference Figures 1 to 4The atomizing bomb shown in the figure includes a base 10, an atomizing bin 20 and an atomizing assembly 30. The atomizing assembly 30 and the atomizing bin 20 are both mounted on the base 10. The atomizing bin 20 has a first chamber 21 and a second chamber 22 that are connected to each other. The side surface of the atomizing bin 20 is also provided with an air inlet channel 23, which is connected to the first chamber 21. The upper end of the second chamber 22 is also connected to an air outlet 41. The atomizing assembly 30 is located at the bottom of the first chamber 21. When in use, the atomizing assembly 30 atomizes the essential oil and disperses it in the first chamber 21. The air flow is blown into the first chamber 21 from the air inlet channel 23, mixed with the atomized particles, and then blown out from the air outlet 41 through the second chamber 22 for release. The atomizing assembly 30 includes a fixing seat 31, an atomizing sheet 32 , electrical connection line 33 and oil guide member 34, wherein one end of the oil guide member 34 can be inserted into the liquid storage tank 50, and the other end is installed in the fixed seat 31. In this embodiment, the oil guide member 34 can be a conventional cotton swab, which can be divided into a vertical section inserted into the liquid storage tank 50 and a horizontal section that can be installed in the fixed seat 31. The atomizer 32 is installed on the horizontal section away from one end of the vertical section. In this embodiment, the liquid storage tank 50 can be a conventional essential oil bottle. The liquid storage tank 50 and the base 10 can be detachably connected through a threaded structure. Specifically, the lower part of the base 10 is in the shape of a sleeve with one end open. The lower end of the base 10 is provided with an internal thread, and the bottle mouth of the liquid storage tank 50 is provided with an external thread matching therewith. A through hole 12 is also provided on the base 10. The oil guide member 34 It can pass through the through hole 12 and be inserted into the liquid storage tank 50. The electrical connection line 33 includes a first wire and a second wire. The first wire is used to connect the positive / negative pole of the atomizing piece 32, and the second wire is correspondingly connected to the negative / positive pole of the atomizing piece 32. When in use, one end of the oil guide member 34 can be extended into the liquid storage tank 50, and then the liquid storage tank 50 and the base 10 are screwed and fixed. After the essential oil in the liquid storage tank 50 is used up, the liquid storage tank 50 can be screwed and removed for replacement or essential oil can be added to the liquid storage tank 50 for reuse. The oil guide member 34 absorbs the essential oil in the liquid storage tank 50 and guides the essential oil to flow to one end of the oil guide member 34 located in the fixing seat 31. The electrical connection line 33 is used to connect the atomizing piece 32 to an external power supply component, and the power supply component supplies the mist through the electrical connection line 33. The atomizing sheet 32 ​​provides energy to enable the atomizing sheet 32 ​​to work, thereby vibrating and atomizing the essential oil on the oil guide 34, and releasing the atomized essential oil particles into the first chamber 21. The first end of the electrical connection line 33 is connected to the atomizing sheet 32, and the second end is connected to the external power supply component after passing through the air inlet channel 23. In this embodiment, when the air flow blows into the first chamber 21 from the air inlet channel 23, the atomized particles attached to the electrical connection line 33 can be blown off, preventing the atomized particles from gathering into droplets on the surface of the electrical connection line 33 and seeping along the electrical connection line 33 to the external electrical components, thereby contaminating or corroding and damaging the electrical components. Therefore, the atomizing structure of the present invention has the advantages that the electrical components are not easily contaminated by essential oils, thereby keeping the atomizing bomb clean and having a long service life.

[0040] In some possible implementations, refer to Figure 5 and Figure 6 As shown, the air inlet channel 23 is integrally formed and arranged at the upper part of the atomization bin 20, and the electrical connection line 33 is suspended in the air inlet channel 23. Such a design can prevent the atomized particles from gathering and accumulating at the junction of the electrical connection line 33 and the inner wall of the air inlet channel 23, and can also avoid the problem that the airflow is difficult to blow to the junction of the electrical connection line 33 and the inner wall of the air inlet channel 23, causing the atomized droplets to seep along the surface of the electrical connection line 33; in this embodiment, the electrical connection line 33 preferably adopts a hard conductor, that is, a plastic copper wire. The advantage is that the electrical connection line 33 can be bent into a fixed shape to ensure that the electrical connection line 33 will not be deformed and contact the inner wall of the air inlet channel 23 during transportation and use.

[0041] In some possible implementations, refer to Figure 3 and Figure 6 As shown, a partition 24 is provided on the atomizing bin 20, and the partition 24 divides the atomizing bin 20 into a first chamber 21 and a second chamber 22. A guide hole 241 is provided in the middle of the lower end of the partition 24, and the first chamber 21 and the second chamber 22 are connected through the guide hole 241, that is, the airflow entrained with the atomized particles can flow from the first chamber 21 to the second chamber 22 through the guide hole 241. The bottom of the first chamber 21 is hollowed out. After the atomizing assembly 30 is fixedly mounted on the base 10, the atomizing bin 20 is mounted on the base 10 and encloses the four sides of the atomizing assembly 30 through the first chamber 21. A guide portion 242 is provided at the bottom of the second chamber 22, and the guide portion 242 is inclined from the partition 24 to the side away from the first chamber 21. The upper portion 242 extends upward, that is, the droplets gathered in the second chamber 22 can flow back to the guide hole 241 along the guide portion 242. A clearance gap 311 is further provided at the upper end of the fixing seat 31 corresponding to the guide hole 241. The purpose is to ensure that the droplets can flow back to the oil guide member 34 through the guide hole 241. The specific process is that when the atomized particles follow the air flow from the first chamber 21 through the guide hole 241 into the second chamber 22, some of the atomized particles may gather into large particles or droplets in the second chamber 22 and drip to the bottom of the second chamber 22. At this time, the droplets can flow back to the oil guide member 34 from the guide portion 242 through the guide hole 241 and the clearance gap 311 in sequence, thereby preventing large particles of liquid or droplets from being released and sprayed out from the air outlet 41.

[0042] In some possible implementations, refer to Figure 5 As shown, the upper surface of the guide portion 242 is an arc surface or is formed by bending and connecting several planes, and the lowest end of the guide portion 242 is located at the guide hole 241; further, the inclination angle of the guide portion 242 relative to the horizontal plane is 45° to 55°.

[0043] In some possible implementations, refer to Figure 4 and Figure 8As shown, the atomizer bomb of the present application also includes a shell 40, which can be covered on the base 10 to form a cavity between the inner surface of the shell 40 and the upper end surface of the base 10, and the atomizer bin 20 and the atomizer assembly 30 are both installed in the cavity. The side surface of the shell 40 is also provided with an air inlet 42, one end of the air inlet 42 is connected to the external blowing component, and the other end is connected to the air inlet channel 23; in this embodiment, the upper end of the atomizer bin 20 is open and sealed by the shell 40. Such a design has the advantage of convenient assembly of the electrical connection line 33. In the present application, the electrical connection line 33 can be loaded from top to bottom and accommodated in the air inlet channel 23, and then the upper end of the first chamber 21, the second chamber 22 and the air inlet channel 23 are closed by the shell 40.

[0044] In some possible implementations, refer to Figure 6 As shown, a horizontal extension portion 231 is formed on the outer side surface of the upper part of the atomizing bin 20, and a vertical extension portion 232 protruding upward is formed on the end of the horizontal extension portion 231 away from the atomizing bin 20. The horizontal extension portion 231, the vertical extension portion 232, the outer wall of the atomizing bin 20 and the inner wall surface of the top of the shell 40 are enclosed to form an air inlet channel 23, and the vertical extension portion 232 protrudes upward to be flush with the upper end surface of the atomizing bin 20; the horizontal extension portion 231 has a first arc surface and a first plane connected in sequence from the first chamber 21 to the outside of the atomizing bin 20, and the vertical extension portion 232 is formed. The extending portion 232 has a second curved surface and a second plane connected in sequence from the first chamber 21 to the outside of the atomization chamber 20. The radii of the first curved surface and the second curved surface are equal and both are smaller than the radius of the curved inner wall of the first chamber 21, and the center of the second curved surface does not coincide with the center of the curved inner wall of the first chamber 21. The purpose is to ensure that the path of the air inlet channel 23 connecting one end of the first chamber 21 is not tangent to the curved inner wall of the first chamber 21, so as to avoid the airflow from rotating along the curved inner wall of the first chamber 21 after entering with the air inlet channel 23 to form a vortex.

[0045] In some possible implementations, refer to Figure 4 and Figure 8As shown, the outer shell 40 is provided with an air outlet channel 43 extending vertically downward from the upper end face of the outer shell 40 to the bottom near the second chamber 22, and the air outlet 41 is arranged at one end of the air outlet channel 43. Specifically, the air outlet 41 can be considered as the end of the air outlet channel 43 near the bottom of the second chamber 22, or as the end of the air outlet channel 43 at the upper end face of the outer shell 40. Such a design has a flow guiding effect on the airflow, so that the airflow carrying the atomized particles can be quickly released from the air outlet channel 43 to disperse to the outside. That is, the airflow flows obliquely upward from the flow guiding hole 241 through the flow guiding portion 242 and then quickly enters the air outlet channel 43 to be quickly released from the air outlet channel 43. Further, the lower end of the air outlet channel 43 is provided with a baffle 44 located on the side of the air outlet channel 43 away from the first chamber 21. Such a design can gather more airflow and blow it out from the air outlet channel 43. Of course, the airflow carrying the atomized particles hits the baffle, causing some liquid droplets to gather and fall from the baffle to the flow guiding portion 242 and then flow back to the oil guiding member 34 along the flow guiding portion 242.

[0046] In some possible implementation manners, referring to Figure 8 As shown, the side of the outer shell 40 opposite to the air inlet 42 is provided with a conduction contact 45 arranged on the mounting cover. The mounting cover is detachably mounted on the side of the outer shell 40 by clamping or buckling structure. The cross section of the atomization chamber 20 is in a waist shape. The first end of the electric connecting wire 33 is connected to the atomization sheet 32, and the second end extends upward from bottom to bottom through the first chamber 21, is bent horizontally and comes out from the air inlet channel 23, is then bent in an arc shape along the outer side of the atomization chamber 20 and is connected to the conduction contact 45. The airflow is blown into the air inlet channel 23 to blow off the atomized particles attached to the electric connecting wire 33.

[0047] In some possible implementation manners, referring to Figure 5 With Figure 6 As shown, the inner wall of the first chamber 21 is further provided with a plurality of baffle ribs 211 extending in the through direction of the first chamber 21. At least one baffle rib 211 is arranged on the arc-shaped inner wall near the air inlet channel 23, that is, at least one baffle rib 211 is arranged below the port of the air inlet channel 23. The purpose is that the baffle rib 211 can disturb the airflow blown into the air inlet channel 23, avoid the airflow flowing along the arc-shaped inner wall of the first chamber 21 to form a vortex, and cause the problem that the airflow cannot flow from the flow guiding hole 241 to the second chamber 22. Further, the baffle rib 211 extends vertically downward to a position corresponding in height to the flow guiding hole 241, further avoiding the airflow from forming a vortex at the bottom of the first chamber 21.

[0048] It should be noted that the atomization assembly 30 is mounted at the bottom of the first chamber 21, and therefore the baffle rib 211 also has the effect of fixedly mounting the fixing seat 31 to the base 10.

[0049] In some possible implementations, refer to Figure 5 As shown, a protruding welding line 25 is provided at the lower end of the atomization bin 20, and a welding groove 11 is provided correspondingly on the upper end surface of the base 10. The welding groove 11 is annular, and the atomization bin 20 is ultrasonically welded to the welding groove 11 correspondingly through the protruding welding line 25, so as to be sealed and fixed to the base 10; further, at least one positioning groove is provided on the base 10, and a positioning pin is provided correspondingly at the bottom of the atomization bin 20, and the positioning pin is inserted into the positioning groove during installation.

[0050] The present invention also provides an aromatherapy machine, referring to Figure 9 As shown, the aromatherapy machine includes a host 2 and an atomizer bomb 1 as in the above embodiment. A slot 3 is provided on the host 2 to match the atomizer bomb 1. The atomizer bomb 1 is plug-in connected to the host 2. The host 2 is used to power the atomizer bomb 1 and control it. When in use, the liquid storage tank 50 is first screwed and fixed to the bottom of the atomizer bomb 1. At this time, one end of the oil guide member 34 is inserted into the liquid storage tank 50 and immersed in the stored liquid, and then the liquid storage tank 50 and the atomizer bomb 1 are inserted into the slot 3 together. After turning on the host 2, the host 2 supplies power to the atomizer plate 32, causing the atomizer plate 32 to vibrate and vibrate and atomize the liquid at one end of the oil guide member 34 away from the liquid storage tank 50. The host 2 can also guide external air to be blown into the first chamber 21 from the air inlet channel 23.

[0051] The main unit 2 is equipped with a power supply, a switch, a circuit board, and a fan. The power supply, switch, fan, and the atomizer sheet 32 ​​on the atomizer cartridge 1 are all electrically connected to the circuit board. The circuit board is equipped with a control circuit, and the switch controls the atomizer sheet 32 ​​and the fan through the control circuit of the circuit board. Specifically, an electrical interface is provided on the inner wall of the slot 3. After the atomizer cartridge 1 is inserted into the slot 3, the conductive contact 45 on the atomizer cartridge is connected to the electrical interface. The circuit board can then power the atomizer sheet 32 ​​and control the opening and closing of the atomizer sheet 32 ​​through this electrical interface.
