Description

Technical Field

[0001] This utility model belongs to the technical field of tooth powder spraying, and specifically relates to a moisture-proof tooth powder spraying device. Background Technology

[0002] In traditional oral hygiene, tooth powder is mostly applied by dipping a toothbrush in, which leads to problems such as inaccurate dosage, powder splattering and waste, and uneven cleaning. Tooth powder spraying devices have emerged to address this issue. These devices use air pressure or mechanical pumps to precisely spray a measured amount of tooth powder in atomized form onto the tooth surface, achieving efficient and uniform coverage. They aim to improve cleaning efficiency and enhance the user experience, representing an important technological attempt to automate oral care.

[0003] Existing tooth powder spraying devices require the device to be turned on first, and an appropriate amount of tooth powder to be added to the powder storage tank, ensuring sufficient powder quantity. Then, align and position the nozzle inlet into the mouth, aiming it at the tooth surface. Next, start spraying: Press the start button, and the internal micro-pump or pneumatic system will operate, spraying a measured amount of tooth powder evenly onto the tooth surface in an atomized form. Following this, after spraying, remove the device. At this point, the tooth powder has adhered to the teeth; use a damp toothbrush to brush your teeth as usual to complete the cleaning process. Finally, clean and maintain: Clean the nozzle after use to prevent residual tooth powder from clogging it, and store the equipment properly.

[0004] The biggest problem with existing tooth powder spraying devices is that the amount of tooth powder added at one time cannot be fixed. If it is not used up at once, it will absorb moisture from the air inside the chamber and clump together. This will result in: the tooth powder becoming damp and unable to be sprayed properly; and the humid environment inside the chamber easily breeding microorganisms, causing the tooth powder to mold. Long-term use can harm the user's health.

[0005] To address this issue, a moisture-proof tooth powder spraying device is proposed, which solves the problem of tooth powder getting damp in the storage silo from the root. A device is designed that pre-packages the tooth powder in an independent, sealed, disposable capsule, making it a standard "consumable unit" that achieves "plug and play, use and discard," and is hygienic and has excellent moisture-proof effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a solution that can fundamentally solve the problem of tooth powder getting damp in the storage silo. The design of disposable tooth powder capsules ensures that the powder is completely sealed from the time it leaves the factory until it is used, thus fundamentally avoiding the problem of clumping and deterioration due to air humidity.

[0007] To address one or more of the above-mentioned defects or improvement needs in the existing technology, this utility model provides a moisture-proof tooth powder spraying device, including a shell and a capsule shell. The capsule shell has a hollow structure and is filled with a fixed amount of tooth powder.

[0009] In some embodiments, a nozzle is attached to the end of the nozzle away from the diffuser section.

[0010] In some embodiments, the connecting tube, constriction section, throat, and diffuser section are internally connected and integrally formed into a Venturi tube.

[0011] In some embodiments, an air pump is fixed to the bottom of the contraction section by bolts, the outer wall of the air pump is fixedly connected to the inner wall of the housing by bolts, an air inlet pipe is fixedly connected to the bottom of the air pump by bolts, and an air inlet is provided at the bottom of the housing.

[0022] Please refer to Figure 1-6 A moisture-proof tooth powder spraying device includes a housing 1 and a capsule shell 3. The capsule shell 3 is a hollow structure, filled with a fixed amount of tooth powder. A capsule thread 4 is fixed to the top side of the capsule shell 3, and a hole is opened at the top of the capsule shell 3. A sealing film 5 is adhered to the hole at the top of the capsule shell 3. The housing 1 has a hollow cavity structure. The side of the housing 1 has a concave cavity 21, which fits the shape of the top of the capsule shell 3. The inner wall of the concave cavity 21 has an installation thread 7. The capsule shell 3 and the concave cavity 21 are connected by the capsule thread 4 and the installation thread 7. A star-shaped spike 8 is engaged at the bottom of the concave cavity 21, and a connecting tube 9 is sleeved in the middle of the star-shaped spike 8. The connecting tube 9 extends through the bottom of the concave cavity 21 into the interior of the housing 1. During installation, the capsule shell 3 can be easily installed by rotating the capsule thread 4 and the installation thread 7. During installation, the star-shaped spike 8 at the bottom of the concave hole 21 will puncture the sealing film 5 at the top of the capsule shell 3, allowing the tooth powder to be delivered through the connecting tube 9. The design of the capsule shell 3 ensures that the tooth powder remains completely sealed from the time of manufacture until the moment of use, fundamentally preventing the problem of clumping and deterioration due to humidity. It also ensures consistent dosage each time, avoiding the problem of users misjudging the amount used. The capsule replacement process is simple, clean, and quick, greatly improving the user experience.

[0023] In this embodiment, a throat 13 is fixed to the end of the connecting pipe 9 away from the concave cavity 21. A diffuser section 12 is fixed to the top of the throat 13, and a constriction section 14 is fixed to the bottom of the throat 13. The connecting pipe 9, the constriction section 14, the throat 13, and the diffuser section 12 are internally connected and integrally formed into a Venturi tube.
