[0003] The atomizing body of the aforementioned atomizing nozzle is equipped with an air intake pipe. Large liquid particles in the atomizing chamber can be recovered into the container through the air intake pipe. At the same time, during operation, the air intake pipe can balance the air pressure in the container. However, if the container is tilted or inverted, the liquid in the container will quickly enter the atomizing chamber through the air intake pipe, resulting in leakage. Utility Model Content

[0004] The main purpose of this invention is to provide an atomizing head and atomizing device, which can slow down the leakage rate of liquid when the atomizing head is inverted.

[0005] According to a first aspect of the present invention, an atomizing head is provided, including an atomizing seat and a cover disposed on the atomizing seat. The atomizing seat is provided with a groove, and the cover cooperates with the groove to surround an atomizing cavity. An atomizing nozzle is provided in the atomizing cavity.

[0006] The bottom of the atomizing base is provided with a protrusion for entering an external essential oil bottle. The protrusion has a cavity, and the top of the cavity is provided with a first protrusion. The first protrusion has a first return hole, which connects the groove and the cavity. The bottom of the cavity is provided with a second return hole, which connects the cavity and the external essential oil bottle. There is a gap between the bottom of the first protrusion and the bottom of the cavity.

[0007] In the atomizing head described above, the bottom of the groove is recessed in a direction away from the atomizing cavity to form the protrusion. The atomizing cavity is provided with a plug, and the plug and the protrusion cooperate to form the cavity. The first protrusion is disposed on the plug.

[0008] In the atomizing head described above, the atomizing base is provided with a second protrusion, a third protrusion, and an air inlet. The second protrusion is provided with a first gas channel, and the third protrusion is provided with a first liquid flow channel. The first gas channel is connected to the air inlet.

[0009] The atomizing nozzle is provided with an air outlet and a liquid outlet. The air outlet is connected to the first gas channel, and the liquid outlet is connected to the first liquid flow channel. The air outlet sprays air to allow the liquid outlet to spray out liquid and atomize it.

[0010] In the aforementioned atomizing head, the plug is sleeved on the second protrusion and the third protrusion. The plug is provided with a second gas channel and a second liquid flow channel. The atomizing nozzle is fixed on the plug. The second gas channel connects the first gas channel and the gas outlet, and the second liquid flow channel connects the first liquid flow channel and the liquid outlet.

[0011] In the atomizing head described above, the third protrusion and the protrusion are an integral structure.

[0012] In the atomizing head described above, the bottom of the groove is a slope, which slopes downwards in the direction close to the plug, and the first return hole is lower than the slope.

[0013] According to a second aspect of the present invention, an atomizing device is provided, comprising an atomizing head and an essential oil bottle, wherein the atomizing head is as described in the first aspect, the atomizing base is connected to the essential oil bottle, the protrusion is inserted into the essential oil bottle, and the second return hole connects the cavity and the essential oil bottle.

Through the first and second return liquid holes, the essential oil bottle can be connected to the atomizing chamber to maintain the air pressure inside the essential oil bottle. The liquid remaining in the atomizing chamber can also flow into the concave cavity through the first return liquid hole and then return to the essential oil bottle through the second return liquid hole. When the atomizing head is inverted, the liquid in the essential oil bottle will enter the concave cavity through the second return liquid hole. The liquid will only enter the first return liquid hole and leak into the atomizing chamber after the liquid height in the concave cavity is greater than the height of the first protrusion. This can slow down the leakage rate of the liquid when the atomizing head is inverted. Attached Figure Description

[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Reference Figures 1 to 6 As shown, an atomizing head includes an atomizing base 1 and a cover 2 disposed on the atomizing base 1. The atomizing base 1 has a groove 11, and the cover 2 cooperates with the groove 11 to form an atomizing chamber 3. An atomizing nozzle 4 is disposed in the atomizing chamber 3. The cover 2 has a mist outlet, and the atomizing base 1 also has a mist outlet tube. The atomized essential oil produced by the atomizing nozzle 4 is released into the atomizing chamber 3 and then diffused out through the mist outlet and the mist outlet tube.

[0028] The bottom of the atomizing base 1 is provided with a protrusion 5 that enters the essential oil bottle 8. The protrusion 5 has a cavity 51. The top of the cavity 51 is provided with a first protrusion 6. The first protrusion 6 has a first return hole 61. The first return hole 61 connects the groove 11 and the cavity 51. The bottom of the cavity 51 is provided with a second return hole 52. The second return hole 52 connects the cavity 51 and the essential oil bottle 8. There is a gap between the bottom of the first protrusion 6 and the bottom of the cavity 51.

[0029] When the atomizing head is engaged with the essential oil bottle 8, the protrusion 5 enters the essential oil bottle 8. Through the first return hole 61 and the second return hole 52, the essential oil bottle 8 can be connected to the atomizing chamber 3, thereby maintaining the air pressure inside the essential oil bottle 8. The liquid left in the atomizing chamber 3 can also flow through the first return hole 61 into the concave cavity 51, and then return to the essential oil bottle 8 through the second return hole 52. When the atomizing head is inverted, the liquid in the essential oil bottle 8 will enter the concave cavity 51 through the second return hole 52. The liquid will only enter the first return hole 61 and leak into the atomizing chamber 3 after the height of the liquid in the concave cavity 51 is greater than the height of the first protrusion 6. This can slow down the leakage rate of the liquid when the atomizing head is inverted.

[0030] In this embodiment, the gap between the bottom of the first protrusion 6 and the bottom of the cavity 51 is sufficient to allow liquid to flow. The higher the first protrusion 6 is, the larger the volume of the cavity 51 when inverted. The first protrusion 6 should be as high as possible while ensuring that the gap allows liquid to flow.

[0031] In this embodiment, the bottom of the groove 11 is recessed into a protrusion 5 in the direction away from the atomizing cavity 3, so that the protrusion 5 and the atomizing seat 1 are an integral structure. The atomizing cavity 3 is provided with a plug 7, and the plug 7 and the protrusion 5 cooperate to form a concave cavity 51. The first protrusion 6 is provided on the plug 7.

[0032] The atomizing base 1 is provided with a second protrusion 12, a third protrusion 13 and an air inlet 14. The second protrusion 12 is provided with a first gas channel 121 and the third protrusion 13 is provided with a first liquid flow channel 131. The first gas channel 121 is connected to the air inlet 14.

[0033] The plug 7 is fitted onto the second protrusion 12 and the third protrusion 13. The plug 7 is provided with a second gas channel 71 and a second liquid flow channel 72. The atomizing nozzle 4 is provided with an air outlet 41 and a liquid outlet 42. The atomizing nozzle 4 is fixed on the plug 7. The second gas channel 71 connects the first gas channel 121 and the air outlet 41. The second liquid flow channel 72 connects the first liquid flow channel 131 and the liquid outlet 42.

[0034] The shape of the plug 7 is designed according to the opening of the second protrusion 12, the third protrusion 13 and the protrusion 5, so that the plug 7 can be fitted on the second protrusion 12 and the third protrusion 13, and at the same time block the opening of the protrusion 5. The air inlet 14 is connected to an external air pump. After the gas passes through the first gas channel 121 and the second gas channel 71, it is discharged from the air outlet 41, thereby forming a negative pressure at the output end of the liquid outlet 42, causing the liquid outlet 42 to draw liquid. The liquid passes through the first liquid flow channel 131 and the second liquid flow channel 72 and is discharged from the liquid outlet 42, and is atomized under the impact of the gas.

[0035] The plug 7 is provided with a protrusion for the atomizing nozzle 4 to be fitted. The second gas channel 71 and the second liquid flow channel 72 are located in the protrusion. The plug 7 is tightly fitted with the second protrusion 12, the third protrusion 13 and the atomizing seat 1. The atomizing nozzle 4 is also tightly fitted with the plug 7, thereby preventing liquid from leaking from the connection position.

[0036] The specific structure of the atomizing nozzle 4 in this application can be referred to the atomizing nozzle structure of patent 201920706850.1, and will not be described in detail here.

[0037] In this embodiment, the first liquid flow channel 131 is generally connected to the essential oil bottle 8 through a suction tube. The liquid in the essential oil bottle 8 is drawn through the suction tube. Therefore, when the bottle is inverted, only the liquid in the suction tube will flow to the liquid outlet 42. The amount of liquid in the suction tube is small, and the liquid outlet 42 is small. In addition, the air pressure inside the essential oil bottle 8 is balanced, so the liquid leakage is relatively small.

[0038] In this embodiment, the third protrusion 13 and the protrusion 5 are an integral structure, which can improve the strength of both the third protrusion 13 and the protrusion 5.

[0039] In this embodiment, the bottom of the groove 11 is a slope, which slopes downwards along the direction close to the plug 7. The first return hole 61 is lower than the slope. If the atomized essential oil does not diffuse out of the atomizing chamber 3, it will be collected back to the bottom of the groove 11, flow along the bottom of the groove 11 to the plug 7, and then enter the first return hole 61.

[0040] Reference Figure 7 According to a second aspect of the present invention, an atomizing device is provided, including an atomizing head and an essential oil bottle 8. The atomizing seat 1 is threadedly connected to the essential oil bottle 8, so that the essential oil bottle 8 is replaceable. The protrusion 5 is inserted into the essential oil bottle 8, and the second return hole 52 connects the cavity 51 and the essential oil bottle 8.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
