In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 As shown, the embodiment of the utility model discloses an oil leakage prevention structure, including an anti-leakage ball 1, a support frame 2 and a cover 3. The support frame 2 is used to support the anti-leakage ball 1. The cover 3 is fixed above the support frame 2. The cover 3 is provided with a fluid channel 4 for fluid to pass through. The support frame 2 has a hollow structure. Specifically, when the anti-leakage ball 1 is in the support frame, the fluid can pass through the hollow structure. When the anti-leakage structure is tilted or inverted, the anti-leakage ball 1 blocks the fluid channel 4 to prevent the essential oil from flowing out of the fluid channel 4, thereby achieving an anti-leakage effect.

[0043] In this embodiment, a receiving chamber 5 for receiving the leak-proof ball 1 is provided in the cover 3, the bottom of the receiving chamber 5 is fixed to the top of the support frame 2, a fluid channel 4 is provided above the receiving chamber 5, and the inner diameter of the fluid channel 4 is smaller than the diameter of the leak-proof ball 1; Figure 2 As shown, when the leak-proof structure is inverted, the leak-proof ball 1 is affected by gravity and moves into the accommodating chamber 5, and part of the sphere of the leak-proof ball 1 enters the accommodating ring 501. The accommodating ring 501 is provided with an elastic sealing ring 6 that fits tightly with the leak-proof ball 1 to prevent the essential oil from flowing out of the fluid channel 4. When the leak-proof structure is tilted, since the support frame 2 is a hollow structure, part of the essential oil enters from the hollow structure, and the leak-proof ball 1 is affected by the force of the tilt of the leak-proof structure and the thrust brought by part of the essential oil, so that the leak-proof ball 1 enters the accommodating chamber 5; preferably, when the leak-proof structure is tilted, the height of the leak-proof ball should at least exceed the channel opening of the fluid channel 4 in horizontal height to ensure that the essential oil cannot flow into the fluid channel 4 over the leak-proof ball 1, so as to achieve a sealing and leak-proof effect.

[0044] Preferably, the cover 3 and the support frame 2 are fixed by snap-fitting.

[0045] Preferably, the cover 3 and the support frame 2 are fixed by integral injection molding.

[0046] In this embodiment, an elastic sealing ring 6 is provided in the accommodating cavity 5, so as to achieve a better sealing effect when the anti-leakage ball 1 fits with the accommodating cavity.

[0047] In this embodiment, if Figure 1 , Figure 2 As shown, an annular containing ring 501 is provided on the inner wall of the containing chamber 5 near the fluid channel 4, and the width of the containing chamber 5 is smaller than the width of the containing ring 501, so as to place an elastic sealing ring 6. The elastic sealing ring 6 is arranged in the containing ring 501. When the oil leakage prevention structure is tilted, the anti-leakage ball 1 fits tightly with the elastic sealing ring 6, thereby achieving a good sealing effect and preventing the essential oil from entering the fluid channel 4.

[0048] In the second embodiment, if Figure 4 As shown, an extension wall 502 can also be provided between the accommodating chamber 5 and the fluid channel 4, and the extension wall 502 is a straight extension with a certain slope, preferably an upward slope. This allows a certain buffer slope to be provided at the connection between the accommodating chamber 5 and the fluid channel 4. When the leak-proof structure is tilted or inverted, the leak-proof ball 1 stays in the accommodating chamber 5, and the leak-proof ball 1 is tangent to the extension wall 502, so that the surface of the leak-proof ball 1 fits the extension wall 502, preventing the essential oil from passing through between the accommodating chamber 5 and the leak-proof ball 1, and making the leak-proof ball 1 have a better blocking effect on the fluid channel 4.

[0049] In the third embodiment, if Figure 5When the anti-leakage structure is tilted or inverted, the anti-leakage ball 1 enters the accommodating cavity 5 under the influence of external force, and since the extension wall 502 is provided with an arc-shaped extension structure, the anti-leakage ball 1 and the extension wall 502 fit better, and the sealing effect is better.

[0050] In this embodiment, the anti-leakage ball 1 is made of stainless steel, which can be immersed in essential oils for a long time and has better durability.

[0051] In this embodiment, if Figures 6 to 9 As shown, the support frame 2 includes a side wall 21 and a support bottom surface 22 connected to the bottom of the side wall, and the side wall 21 and / or the support bottom surface 22 are provided with a through hole 23.

[0052] Specifically, the through hole 23 may be provided only on the side wall 21, and the shape of the through hole 23 includes but is not limited to an elongated shape, a dot shape, such as Figure 6 , Figure 7 As shown, the supporting bottom surface 22 of the supporting frame 2 is used to support the anti-leakage ball 1. When the anti-leakage structure is in a normal placement state, the anti-leakage ball 1 rests on the supporting bottom surface 22, and the anti-leakage ball 1 does not block the through hole 23 provided on the supporting frame 2, so as to ensure that the fluid can normally pass through the through hole 23 and flow into the fluid channel 4.

[0053] Alternatively, the through hole 23 may also be provided only on the support bottom surface 22, and the shape of the through hole 23 includes but is not limited to an elongated shape, a dot shape, such as Figure 6 , Figure 7 As shown, when the leak-proof structure is in a normal placement state, the leak-proof ball 1 rests on the bottom of the support frame 2, and the leak-proof ball 1 does not block the several small holes on the surface of the support frame 2, and the fluid can pass through the through hole 23 of the support bottom surface 22.

[0054] Alternatively, the through hole 23 can also be provided on the side wall 21 and the support bottom surface 22 at the same time. The shape of the through hole 23 includes but is not limited to an elongated shape, a dot shape, such as Figure 6 , Figure 7 The anti-leakage ball 1 is placed on the supporting bottom surface 22, and the fluid can pass through the through hole 23.

[0055] Preferably, an elastic convex ring 601 is provided in the elastic sealing ring 6. When the leak-proof structure is inverted, the leak-proof ball 1 is moved to the accommodating chamber 5 due to gravity, and part of the ball body of the leak-proof ball 1 enters the accommodating ring 501 and fits with the elastic sealing ring 6. The elastic convex ring 601 is squeezed and deformed by the leak-proof ball 1, and the sealing effect is better.

[0056] In addition, if Figure 2As shown, the utility model also provides a fragrance diffuser including the above-mentioned anti-oil leakage structure, and the anti-oil leakage structure is located in the atomizing chamber 7. Specifically, the fragrance diffuser includes an essential oil bottle 9, a specific device for atomizing the essential oil in the essential oil bottle 9, and an anti-oil leakage structure provided in the atomizing chamber 7. The anti-oil leakage structure is applied to the fragrance diffuser. The atomizing device inside the fragrance diffuser generates a fluid, and the fluid moves upward, passes through the support frame 2 with a hollow structure, enters the accommodating chamber 5 in the cover 3, and finally overflows through the fluid channel 4. Specifically, the working principle of the fragrance diffuser is to generate high-speed and high-pressure gas through the atomizing device to crush the essential oil in the essential oil bottle 9 into fine fluids, which overflow into the atomizing chamber 7 through the atomizing core 10. The fluid moves upward and enters the atomizing chamber 7. A leak-proof device is provided on the top of the atomizing chamber 7. The fluid enters the accommodating chamber 5 through the hollow support frame 2. Under normal conditions, the leak-proof ball 1 will not block the fluid channel 4, and the fluid can overflow the fragrance diffuser from the fluid channel 4. As shown Figure 2 As shown in a, when the aroma diffuser is tilted, the leak-proof ball 1 moves from the support frame 2 to the accommodating chamber 5, and fits with the elastic sealing ring 6 in the accommodating ring 501. The essential oil in the essential oil bottle 9 flows into the atomization chamber 7, and then flows into the hollow structure of the support frame 2 and stays in the accommodating chamber 5. Since the leak-proof ball 1 fits tightly with the elastic sealing ring 6 and blocks the fluid channel 4, the essential oil will not flow into the fluid channel, thereby avoiding the waste of essential oil and the outflow of essential oil to contaminate external objects, which makes the user experience better.

[0057] In addition, if Figure 3 As shown in b, the utility model also provides another aroma diffuser, wherein the anti-leakage structure is located in the oil return port 8, specifically, the anti-leakage structure is arranged on the top of the essential oil bottle 9 and is connected with the atomization chamber 7; when the aroma diffuser is in a normal placement state, the anti-leakage ball rests on the bottom surface of the support frame 2; when the aroma diffuser falls over, the anti-leakage ball 1 at the oil return port 8 blocks the oil return port 8 to prevent the essential oil in the essential oil bottle 9 from flowing out of the oil return port 8; when the aroma diffuser returns to a normal placement state, the anti-leakage ball 1 returns to the support frame 2, and the essential oil in the atomization chamber 7 flows into the essential oil bottle 9 through the oil return port 8, with good sealing performance, and at the same time the essential oil in the atomization chamber 7 is recovered and reused, thereby saving costs.

[0058] like Figure 3As shown, the utility model also includes a fragrance diffuser, and both the atomizing chamber 7 and the oil return port 8 are provided with leak-proof structures. Specifically, an oil-leakage-proof structure is provided at the top of the atomizing chamber 7, and an oil return port 8 is provided at the top of the essential oil bottle 9. Another leak-proof structure is provided at the oil return port 8, and the leak-proof structure at the oil return port 8 enables the atomizing chamber 7 to communicate with the essential oil bottle 9. When the fragrance diffuser is in a normal placement state, the leak-proof structure at the top of the atomizing chamber 7 rests on the corresponding support frame 2, and the atomizing device of the fragrance diffuser will generate high-speed, high-pressure gas to crush the essential oil in the essential oil bottle 9 into fine fluids, and the fluid enters the atomizing chamber 7 through the atomizing core 10. The fluid moves upward and enters the accommodating chamber 5 inside the cover 3 through the hollow structure of the support frame 2. The leak-proof ball 1 will not block the fluid channel 4 when the fragrance diffuser is placed normally, and the fluid overflows the fragrance diffuser along the fluid channel 4. When the aroma diffuser is tilted, the anti-leakage ball 1 at the atomizing chamber 7 blocks the fluid channel 4 by the tilting force, and a small amount of essential oil flows out from the atomizing core 10 to the accommodating chamber 5. Since the anti-leakage ball 1 blocks the fluid channel 4, the essential oil will not flow out, avoiding the waste of essential oil and contamination of external objects; at the same time, the anti-leakage structure at the oil return port 8 blocks the oil return port 8 by the tilting force, preventing the essential oil in the essential oil bottle 9 from flowing out from the oil return port 8. When the aroma diffuser returns to the normal placement state, the essential oil in the accommodating chamber 5 drips into the atomizing chamber 7, the anti-leakage ball 1 returns to the support frame 2, and the anti-leakage ball 1 at the oil return port 8 returns to the corresponding support frame 2. Correspondingly, the oil return port 8 is no longer blocked by the anti-leakage ball 1, and the essential oil on the top of the atomizing chamber 7 drips down to the bottom of the atomizing chamber 7, and then flows down along the oil return port 8. Since the support frame 2 at the oil return port 8 is a hollow structure, the essential oil can return from the atomizing chamber 7 to the essential oil bottle 9.

[0059] The utility model provides a fragrance diffuser with significant advantages: when the fragrance diffuser is tilted, the leak-proof structure at the atomizing chamber 7 blocks the fluid channel 4 to prevent the essential oil from flowing out, thereby avoiding the waste of the essential oil and at the same time avoiding the leakage of the essential oil to pollute external objects, thereby improving the user's experience; the leak-proof structure at the oil return port 8 blocks the oil return port 8 to prevent the essential oil in the essential oil bottle 9 from flowing out; when the fragrance diffuser returns to a normal placement state, the oil return port 8 returns to the corresponding support frame 2, and the essential oil in the atomizing chamber 7 is recovered into the essential oil bottle 9, thereby playing a recycling role, saving materials and providing a better user experience.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
