Abstract
Description
Technical Field
[0001] This application relates to the field of diffuser technology, and in particular to a diffuser that prevents oil leakage. Background Technology
[0002] A diffuser, a device used for indoor fragrance diffusion, transforms essential oils or solutions into fine fragrance particles that disperse into the air, creating a comfortable and pleasant atmosphere. Early diffusers mostly used a simple evaporation principle, allowing the perfume to evaporate freely. However, this method resulted in insufficient atomization of the essential oils, limiting the diffusion effect. Later, various technologies were developed, such as using an air compressor to introduce high-pressure compressed air into the atomizing head, causing the high-pressure air to impact the essential oils at high speed to achieve atomization; and ultrasonic atomization technology that uses ultrasonic vibration to break down liquids into tiny particles.
[0003] In existing technology, aroma diffusers mainly consist of a liquid storage bottle, an atomizing device, a control circuit, and a housing. The liquid storage bottle is used to store aroma essential oils and is connected to the diffuser body via an interface; the atomizing device is responsible for converting the essential oils into mist and generally consists of components such as an atomizing plate and a fan.
[0004] Regarding the aforementioned technologies, the inventors believe that the connection between the liquid storage bottle and the diffuser body is prone to leakage due to loose connection, which wastes essential oils and reduces the user experience. Utility Model Content
[0005] The purpose of this application is to provide a leak-proof diffuser to improve the problem of leakage caused by loose connection between the liquid storage bottle and the diffuser body.
[0006] This application provides a diffuser for preventing oil leakage, which adopts the following technical solution:
[0007] A leak-proof aroma diffuser includes a diffuser body with a mounting frame. An atomizer is mounted on the mounting frame above the diffuser body. The atomizer is connected to a storage bottle and has a straw. The storage bottle has a mouth and a ring plate coaxial with the mouth, with a gap groove between the ring plate and the mouth. A connecting ring plate is mounted on the bottom surface of the atomizer, fitting against both sides of the gap groove. The inner wall of the ring plate is threadedly connected to the outer wall of the connecting ring plate. A sealing gasket is located inside the connecting ring plate within the atomizer, and the sealing gasket abuts against the mouth.
[0008] By adopting the above technical solution, a ring plate coaxial with the bottle opening is attached to the inner and outer sides of the ring plate as an auxiliary fixing and sealing structure. The ring plate at the bottom of the atomizer is threadedly connected to the ring plate of the liquid storage bottle, which not only enhances the stability of the connection and reduces the impact of shaking, but also effectively reduces gaps and lowers the risk of oil leakage. The sealing gasket inside the atomizer abuts against the bottle opening, improving the sealing performance of the bottle opening and helping to prevent essential oil leakage.
[0009] Optionally, the sealing gasket is provided with a groove for engaging the bottle opening.
[0010] By adopting the above technical solution, the sealing gasket is set with a groove to engage with the bottle mouth, so that the sealing gasket fits more tightly with the bottle mouth and the positioning is more accurate, thereby further enhancing the sealing effect.
[0011] Optionally, a raised ring is provided in the slot, and a ring groove is provided at the bottle mouth for the raised ring to be inserted.
[0012] By adopting the above technical solution, a raised ring is set in the slot and a corresponding ring groove is set at the bottle mouth. The two cooperate with each other, and the raised ring in the slot and the ring groove at the bottle mouth fit together, which not only enhances the sealing effect, but also improves the stability of the connection between the sealing gasket and the bottle mouth.
[0013] Optionally, the inner wall of the connecting ring plate is provided with a plurality of sealing rings I that abut against the outer wall of the bottle opening in the vertical direction, and the outer wall of the bottle opening is provided with a plurality of sealing rings II that abut against the inner wall of the connecting ring plate in the vertical direction.
[0014] By adopting the above technical solution, sealing ring one and sealing ring two apply pressure to the connection from both the inside and outside directions to form a tight seal, which greatly enhances the ability to resist essential oil leakage and ensures tightness of the connection.
[0015] Optionally, the outer wall of the bottle opening is provided with a plurality of sealing grooves one corresponding to the sealing ring one, and the inner wall of the connecting ring plate is provided with a sealing groove two corresponding to the sealing ring two.
[0016] By adopting the above technical solution, after the sealing ring is embedded in the sealing groove, not only is the sealing contact area increased, but the sealing groove can also restrict the movement of the sealing ring, so that it always maintains a good sealing state and further reduces the chance of oil leakage.
[0017] Optionally, the first sealing ring and the second sealing ring are staggered.
[0018] By adopting the above technical solution, the staggered arrangement avoids the overlap of weak points in the seal, making the entire sealing structure more stable and comprehensive. Even if one part of the seal is slightly inadequate, the staggered seal can still play a supplementary protective role.
[0019] Optionally, the outer wall of the bottle opening is provided with a first mounting groove for the two sets of sealing rings to engage, and the inner wall of the connecting ring plate is provided with a second mounting groove for the one set of sealing rings to engage.
[0020] By adopting the above technical solution, the installation and disassembly of sealing ring one and sealing ring two are facilitated, the operation is convenient, and the maintenance cost is reduced; on the other hand, the mounting groove can fix the position of the sealing ring and improve the fixing stability of the sealing ring.
[0021] Optionally, the top of the ring plate abuts against the mounting bracket.
[0022] By adopting the above technical solution, the rigid support of the mounting bracket is used to apply an additional downward pressure to the ring plate of the liquid storage bottle, making the threaded connection between the ring plate and the connecting ring plate tighter. At the same time, it also helps to stabilize the overall position of the liquid storage bottle, further strengthens the seal, and reduces the oil leakage problem that may be caused by loosening.
[0023] Optionally, the height of the connecting ring plate is less than the depth of the spacer groove.
[0024] By adopting the above technical solution, even if a small amount of essential oil leaks from other sealing links, it can be temporarily contained in the spacer, which helps to prevent leakage from flowing to other parts of the diffuser and causing pollution.
[0025] In summary, this application includes at least one of the following beneficial technical effects of an oil-leakage-proof diffuser:
[0026] 1. By setting a ring plate that fits on the inner and outer sides of the ring plate coaxial with the bottle mouth, it serves as an auxiliary fixing and sealing structure. The ring plate on the bottom of the atomizer is connected to the ring plate of the liquid storage bottle by threads, which not only enhances the stability of the connection and reduces the impact of shaking, but also effectively reduces gaps and reduces the risk of oil leakage. The sealing gasket inside the atomizer abuts against the bottle mouth, improving the sealing performance of the bottle mouth and helping to prevent essential oil leakage.
[0027] 2. By utilizing the rigid support of the mounting bracket, an additional downward pressure is applied to the ring plate of the liquid storage bottle, making the threaded connection between the ring plate and the connecting ring plate tighter. This also helps to stabilize the overall position of the liquid storage bottle, further strengthening the seal and reducing oil leakage problems that may be caused by loosening.
[0028] 3. Even if a small amount of essential oil leaks from other sealed parts, it can be temporarily contained in the spacer, which helps prevent leakage from flowing to other parts of the diffuser and causing contamination. Attached Figure Description
