DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

In order to make the invention purpose, the technical scheme and the technical effect more clearly be understood, the invention is further explained in combination with the concrete embodiment below. It should be understood that the specific embodiments described herein are only used to interpret the invention and are not used to limit the invention.

Referring to FIG. 1-10, the present invention provides an oil leaking prevention structure and an aromatherapy machine with the same.

Referring to FIG. 1, FIG. 2, FIG. 4 and FIG. 8, the oil leaking prevention structure is mainly used in the aromatherapy machine in car or in room, the aromatherapy machine includes the spraying, port 110 and the liquid reservoir 120. Specifically, the oil leaking prevention structure includes a rectifying chamber 200 arranged in the aromatherapy machine, one side of the rectifying chamber 200 is communicated with the spraying port 110, the other end thereof is communicated with the liquid reservoir 120. Some essential oil is stored in the liquid reservoir 120 and atomized into mist. The mist enters the rectifying chamber 200 and is ejected from the spraying port 110. The rectifying chamber 200 can reduce the flowing rate of the mist and make it flow evenly, and keeps the flowing amount of the mist stable when it is ejected from spraying port 110, thereby improving the fluency of atomization and improving the user's experience.

Referring to FIG. 4, FIG. 5 and FIG. 8, the rectifying chamber 200 contains a rectifying portion 210 and a leak-proof portion 220, the rectifying portion 210 is disposed at a side of the spraying port 110. When the mist enters the rectifying chamber 200, it enters the rectifying portion 210 firstly. The leak-proof portion 220 is disposed between the spraying port 110 and the rectifying portion 210. Specifically, the rectifying chamber 200 is communicated with the leak-proof portion 220, which ensures that the mist in the rectifying chamber 200 can enter the leak-proof portion 220 and is ejected from the spraying port 110, and avoids the leak-proof portion 220 from affecting the flowing amount of the mist. The rectifying portion 210 is communicated with the leak-proof portion 220, a part of the mist in the liquid reservoir 120 can enter the leak-proof portion 220 directly by passing through the rectifying portion 210 and is ejected from the spraying port 110. The two flowing paths of the mist ensures the mist at the spraying port 110 to keep stable flowing rate at any time, thereby stabilizing the flowing amount of the mist ejected from the spraying port 110.

The leak-proof portion 220 is also used for preventing the essential oil from leaking from the spraying port 110 when the liquid reservoir 120 is topple and fall.

When the aromatherapy machine is topple and fall, the essential oil in, the liquid reservoir 120 will enter the rectifying chamber 200, at this time, the leak-proof portion 220 can block the spraying port 110 and avoid the essential oil from flowing out from the spraying port 110. The leak-proof portion 220 in the present invention can keep the flowing rate of the mist in the spraying port 110 consistent while ensuring the leakage proof function, which ensures the incense effect and the user's experience. Compared with the oil leaking prevention structure disclosed in Chinese Utility Model Patent No.: ZL201921251007.5, the oil leaking prevention structure of aromatherapy machine in present invention has better leakage proof effect and better user's experience.

In some embodiments, referring to FIG. 4FIG. 5 and FIG. 8, the leak-proof portion 220 includes a leak-proof tube 221, one end thereof is communicated with the spraying port 110, the other end thereof is connected with a centre of a bottom 212 of the rectifying portion 210. The sidewall 224 of the leak-proof tube 221 adopts a hollowed-out structure, and the mist in rectifying chamber 200 enters the leak-proof tube 221 from the hollowed-out structure. The bottom 212 of the rectifying portion 210 also adopts the other hollowed-out structure 214, the mist in the liquid reservoir 120 enters the rectifying chamber 200 from the other hollowed-out structure 214.

In some embodiments, referring to FIG. 4, FIG. 5 and FIG. 8, a steel ball 222 is disposed in the leak-proof tube 221, the diameter of the steel ball 222 is not less than that of the leak-proof tube 221. Specifically, the steel ball 222 is limited to move in the leak-proof tube 221. When the steel ball 222 rolls in the leak-proof tube 221, the leak-proof tube 221 is communicated with the rectifying chamber 200 through the hollowed-out structure of the leak-proof tube 221, the rolling of the steel ball 222 does not affect the mist to enter the leak-proof tube 221 from the hollowed-out structure. The steel ball 222 rolls in the leak-proof tube 221 under the control of the gravity, when the aromatherapy machine is toppled and fall, the steel ball 333 moves toward the spraying port 110 under the function of the gravity and blocks the spraying port 110 so that the mist can not be ejected from the spraying port 110. That the diameter of the steel ball 222 is not less than that of the leak-proof tube 221 also can prevent the steel ball 222 from rolling out of the leak-proof tube 221 a to enter the rectifying chamber 200.

It should be understood that the diameter of the steel ball 222 is not less than that of the leak-proof tube 221 is not the only implementation, in some other embodiment, the diameter of the steel ball 222 is bigger than that of the leak-proof tube 221, and the diameter of the steel ball 222 is bigger than that of the hollowed-out structure of the leak-proof tube 221, thereby ensuring the steel ball 222 is limited to active in the leak-proof tube 221. The present invention does not limit the diameter specifications of the leak-proof tube 221. Without leaving the basic idea of the present invention, the change of the diameter specifications of the steel ball 222 should be deemed to be within the protection scope defined by the present invention.

Specifically, the steel ball 222 is made from stainless steel, it should be understood that, the steel ball 222 using stainless steel material is not the only implementation, in some other embodiments, the steel ball 222 has an internal metal covered by fluorine adhesive layer (i.e. fluorine rubber), which ensures that the steel ball 222 has a certain mass and can roll under gravity. The structure and the materials of the steel ball 222 are not limited herein, it should be understood that without leaving the basic idea of the present invention, the change of the structure and the materials of the steel ball 222 should be deemed to be within the protection scope defined by the present invention.

In some embodiments, referring to FIG. 4, FIG. 5 and FIG. 8, the bottom 212 of the rectifying, portion 210 is provided with a hole 211 at a corresponding position to the leak-proof tube 221, but the hole 211 is off: center of the bottom. Specifically, the hole 221 is communicated with the leak-proof tube 221, the mist in the liquid reservoir 120 also can enter the leak-proof tube 221 from the hole 211 except entering the rectifying chamber 200 from the other hollowed-out structure 214 of the rectifying portion 210.

When the steel ball 222 contacts with the rectifying portion 210, it contacts the centre of the bottom 212 of the rectifying portion 210, the hole 211 is communicated with the leak-proof tube 221. The hole 211 in the bottom 212 of the rectifying portion 210 is arranged at an off-center position thereof. When the aromatherapy machine work normally, the steel ball 222 is located at the bottom of the leak-proof tube 22, that is to say that the steel ball 222 is attached to the bottom 2120 of the rectifying chamber 210, but does not block the hole 211. At this time, the a part of the mist in the liquid reservoir 120 enters the leak-proof tube 221 from the hole 211, after the mist touches the steel ball 222, it moves along a gap between the steel ball 222 and the leak-proof tube 221 toward the spray port 110. The hole 211 provides one more flowing path, and assists the flow amount of the mist of the spraying port 110 consistent to ensure the quality of the spraying mist. When the mist enters the leak-proof tube 221 from the hole 211 and touches the steel ball 222, the mist also can lubricate the steel ball 222, ensuring that the steel ball 222 rolls smoothly in the leak-proof tube 221, and ensuring that the steel ball 222 can still fit with the spray port 110 after it is used for along time, and ensuring the leakage prevention effect.

In some embodiments, referring to FIG. 4, FIG. 5 and FIG. 8, the rectifying portion 220 is a recessing structure, that is the middle of the rectifying portion 210 is recessed towards the liquid reservoir 120 so that the essential oil in the rectifying chamber 200 reflow into the liquid reservoir 120. Specifically, the bottom 212 of the rectifying portion 210 is flat and the middle thereof is concave toward the liquid reservoir 120. When the mist is liquid accumulation in the rectifying chamber 200, the liquid accumulation can gather at the recessing structure, then reflow into the liquid reservoir 120 from the hole 211, for atomization again.

In some embodiments, referring to FIG. 4, FIG. 5 and FIG. 8, the leak-proof portion 220 includes an elastic ring 223 arranged at a side of the leak-proof tube 221 close to the spraying port 110, one side of the elastic ring 223 is connected with the spraying port 110, the other side thereof is horn-shaped and contacts with the steel ball 222 elastically. However when the steel wall 222 and the elastic ring 223 contacts, the rectifying chamber 200 is separated with the spraying port 110 so as to prevent the essential oil in the liquid reservoir 120 from leaking from the spraying port 110. Specifically, the elastic ring 223 is horn-shaped, the diameter of the elastic ring 223 is bigger than that of the steel wall 222. And the elastic ring 223 is made from fluorine rubber or butyl fine rubber, which has good corrosion resistance to the essential oil, which can avoid increasing the gap between the elastic ring 233 and the steel ball 222 after being used for a long time, and ensure the oil leakage sealing performance of the elastic ring 233.

Specifically, compared with Chinese Utility Model Patent No.: ZL201921251007.5, which discloses oil leaking prevention structure, the steel ball directly contacts with the spraying port 110. As the increase of service time, the aging of spray nozzle 110 is easy to cause cracks in the blocking state. While in the embodiments in the present invention, the elastic ring 223 as a medium between the spraying port 110 and the steel ball 222, the steel ball 222 contacts the elastic leak ring 223 to enable sealing of the spraying port 110. The elastic ring 223 is made from fluorine rubber or butyl fine rubber, which has good corrosion resistance to the essential oil, which can avoid the oil leakage sealing performance of the elastic ring 233 from reducing. The essential oil at the surface of the steel ball 222 can lubricate the steel ball 222, keep the elasticity of the elastic leakage ring 223 for a long time and not easy to age.

In some embodiments, referring to FIG. 4, FIG. 5 and FIG. 8, the sidewall 224 of the leak-proof tube 221 closed to the elastic ring 223 is provided with a limited portion 221-1 for the steel ball, the limited portion 221 is disposed around the inner wall of the leak-proof tube 221. When the steel wall 222 and the elastic ring 223 contacts, the limited portion 221-1 limits the steel ball 222 and defines a deformation degree of the elastic ring 223.

Specifically, the steel ball 222 contacts the elastic ring 223 to deform it, when the steel ball 222 compresses the limited portion 221-1, the maximum stroke of the steel ball 222 is reached, at this time, the elastic ring 223 reaches the optimal deformation, the limited portion 221-1 prevents the deformation of the elastic ring from becoming too large and causes the steel ball 222 to be unable to fall back when the aromatherapy machine is placed upright.

In some embodiments, referring to FIG. 1-4, FIG. 8 and FIG. 9, the aromatherapy machine includes the above oil leak prevention structure, a shell 100 and a pump mechanism 130 disposed in the shell 100. The pump mechanism 130 is wrapped with by materials such as cotton and velvet cloth that can reduce the noise and reduce the working noise of the pump mechanism 130. The pump mechanism 130 is communicated with the liquid reservoir 120, the pump mechanism 130 is used for atomizing the essential oil in the liquid reservoir 120.

Referring to FIG. 7, a leak-proof ring 140 is disposed between the rectifying chamber 200 and the liquid reservoir 120, the leak-proof ring 140 is used for preventing the essential oil in the liquid reservoir 120 from leaking from a connection gap. Specifically, the elastic ring 223 is made from fluorine rubber or butyl fine rubber, which has good corrosion resistance to the essential oil and can avoid the oil leakage sealing performance of the elastic ring 233 from reducing.

The connecting tube 230 is made of polypropylene (PP), which has good corrosion resistance to essential essential oil and ensures the service life of the atomized connection pipe 230.

Specifically, the connecting tube 230 and the rectifying chamber 240 are connected by plugging and pulling ways, which is convenient for users to disassemble the connecting tube 230 and clean it. Compared with a threaded connection, the plugging and pulling ways in the present invention can pull the connecting tube 230 directly, which is faster.

Referring to FIG. 7, the end section of the delivering hose 240 is V-shaped, that is two sides of the end of the delivering hose 240 is open. When the end of the delivering hose 240 is attached to the bottom of the liquid reservoir 120, the essential oil in the liquid reservoir 120 can enter the delivering hose 240 from the two sides of the end thereof, which prevents the delivering hose 240 from being blocked by the sidewall of the liquid reservoir 120, resulting in the essential oil can not be extracted.

Referring to FIG. 6, the pore size of the positive pressure hole 234 is gradually narrowed from a side close to the oil outlet hole 233 to a side away from the oil outlet hole 233. It can make the essential oil spray faster from the positive pressure hole 234, reduce the flow amount, thereby making the essential oil better contact with the high-speed airflow and atomize.

Referring to FIG. 4 and FIG. 7, the delivering hose 240 and the oil outlet hole 233 are connected bu an inner plugging way, that is the delivering hose 240 inserts into the oil outlet hole 233, which can effectively prevent air leakage at the joins of the oil outlet hole 233 and the delivering hose 240. In some other embodiments, it may be possible that the delivering hose 240 surrounds the oil outlet hole 233 to make the two more closely connect.

Specifically, the pore size of the increasing pressure hole 232 is gradually narrowed to increase the gas flow rate in the increasing pressure hole 232 to blow away the air near the positive pressure bore 234. At this time, a side of the positive pressure hole 234, blown away the air, is in a low pressure state, and the side of the positive pressure hole 234, connected to the oil outlet hole 233, is communicated with the essential oil in the liquid reservoir 120. A pressure of the liquid surface of the essential oil causes the essential oil to enter the oil hole 233 through the delivering hose 240 and then be ejected through the positive pressure hole 234. The essential oil ejected from the positive pressure hole 234 meets the gas from the increasing pressure hole 232, causing the essential oil to atomize into the mist.
