Description

Technical Field

[0001] This utility model belongs to the field of dental technology, specifically a dental handpiece air gun drying waste liquid collector. Background Technology

[0002] Dental handpieces are the most commonly used and important instruments in dentistry. Cleaning and maintaining dental handpieces is a key aspect of ensuring medical quality. However, due to the structural characteristics of dental handpieces, a significant amount of liquid residue remains after cleaning and lubrication.

[0003] Residual liquid inside a dental handpiece can lead to sterilization failure and increase the risk of hospital-acquired infections. Effectively removing residual liquid from the dental handpiece can improve the sterilization quality of the handpiece and reduce the risk of damage to the handpiece bearings.

[0004] Currently, air gun drying of the dental handpiece lumen is one of the commonly used methods to remove residual liquid in the handpiece lumen before and after cleaning and lubrication. When the air gun dries the dental handpiece lumen, waste liquid in the lumen will be sprayed out from the insertion hole at the front end of the dental handpiece, generating aerosols and polluting the environment. Therefore, a dental handpiece air gun drying waste liquid collector is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a dental handpiece air gun drying waste liquid collector.

[0007] Preferably, the top of the transparent funnel lid is hinged with a clamping rod by a torsion spring, and the rods are arranged in a circumferential array.

[0008] Preferably, a protective plate is fixed to the inner side wall of the clamping rod; a friction pad is provided at the end of the protective plate.

[0009] Preferably, a support pad is fixed to the end of the liquid collection bottle.

[0010] Preferably, a sealing ring is installed at the bottom of the transparent funnel lid; the diameter of the insertion hole is 13mm.

[0011] The beneficial effects of this utility model are:

[0012] This invention provides a waste liquid collector for dental handpiece air gun drying. When guiding the liquid inside the dental handpiece air gun, the lower section of the collection bottle is a container for collecting the accumulated liquid, and the upper section is a hollow frame to support the sealing ring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a dental handpiece air gun drying waste liquid collector, including a collection bottle 1. A perforated frame is installed on the inner wall of the collection bottle 1. A transparent funnel 23 is installed on the top of the perforated frame. A transparent funnel cover 21 is installed on the top of the collection bottle 1. An insertion hole 22 is provided on the top of the transparent funnel cover 21. An exhaust port 11 is provided at the end of the collection bottle 1, located at the end of the transparent funnel 23. During operation, when guiding the liquid inside the dental handpiece air gun, the lower section of the collection bottle 1 is a container for collecting the accumulated liquid, and the upper section is a perforated frame for supporting the sealing ring 24. The transparent funnel cover 21 is circular and has six insertion holes 22 in the center, primarily for inserting the dental handpiece. By assembling the collection bottle 1, transparent funnel 23, and transparent funnel cover 21 together, the dental handpiece is inserted... Inside the insertion port 22, the cavity of the dental handpiece is dried with an air gun. The liquid inside the dental handpiece flows out from the front port and flows down into the collection bottle 1 through the transparent funnel 23 under the action of gravity. During the air gun drying process, the color of the liquid blown out of the dental handpiece inside the transparent funnel 23 can be observed with the naked eye to judge the cleanliness of the dental handpiece, reducing aerosol generation and environmental pollution. This collection device has a diameter of 20 cm, occupies a small area, and is easy to operate. During the operation, the flow of waste liquid from the dental handpiece cavity can be observed, which helps to judge the cleanliness of the dental handpiece cavity and reduce aerosol generation. The collection bottle 1 is detachable for easy cleaning. Several vent holes 11 are opened at the end of the collection bottle 1 to ensure equal internal and external pressure, preventing the transparent funnel cover 21 from being lifted by air pressure when the air gun blows air into the cavity.

[0025] Furthermore, such as Figures 1-3 As shown, the top of the transparent funnel cover 21 is hinged with a clamping rod 25 by a torsion spring and arranged in a circumferential array. During operation, when the dental handpiece is inserted into the insertion hole 22, the clamping rod 25 is squeezed, causing it to rotate towards its end, thereby squeezing the torsion spring to generate elastic force. The clamping rod 25 is then clamped to the outer wall of the dental handpiece by the elastic force of the torsion spring for clamping and fixing.

[0026] Furthermore, such as Figures 1-3As shown, a protective plate 26 is fixed to the inner wall of the clamping rod 25; a friction pad 27 is provided at the end of the protective plate 26; during operation, by installing the protective plate 26 and the friction pad 27 on the inner wall of the clamping rod 25, the protective plate 26 protects the clamped mobile phone air gun, and the friction pad 27 increases the friction between the protective plate 26 and the mobile phone air gun, thereby improving the clamping effect of the protective plate 26.

[0027] Furthermore, such as Figures 1-3 As shown, a support and fixing pad 28 is fixed to the end of the liquid collection bottle 1. During operation, by installing the support and fixing pad 28 at the end of the liquid collection bottle 1, the liquid collection bottle 1 is placed against the table, which provides support and reduces the problem of the liquid collection bottle 1 tilting due to table shaking.

[0028] Furthermore, such as Figures 1-2 As shown, a sealing ring 24 is installed at the bottom of the transparent funnel lid 21; the diameter of the insertion hole 22 is 13mm; during operation, by installing the sealing ring 24 at the bottom of the transparent funnel lid 21, the transparent funnel lid 21 can achieve a sealing effect when covering the top of the collection bottle 1.

[0029] Working Principle: When guiding the liquid inside the dental handpiece air gun, the lower section of the collection bottle 1 is a container for collecting the liquid, and the upper section is a hollow frame to support the sealing ring 24. The transparent funnel cover 21 is circular with six insertion holes 22 in the center, which are mainly used as insertion holes for the dental handpiece. By assembling the collection bottle 1, transparent funnel 23, and transparent funnel cover 21 together, the dental handpiece is inserted into the insertion holes 22. The air gun is used to dry the cavity of the dental handpiece. The liquid inside the dental handpiece flows out from the front end of the handpiece and flows down into the collection bottle 1 under gravity in the transparent funnel 23. During the air gun drying process, the color of the liquid blown out of the dental handpiece inside the transparent funnel 23 can be visually observed to determine the cleanliness of the dental handpiece, reducing aerosol generation and environmental pollution. This collection device has a diameter of 20 cm, occupies a small area, and is easy to operate. During operation, the flow of waste liquid from the dental handpiece cavity can be observed, which helps to determine the cleanliness of the dental handpiece cavity and reduce aerosol generation. The collection bottle 1 is detachable for easy cleaning. When the dental handpiece is inserted into the socket 22, the clamping rod 25 is squeezed, causing it to rotate towards its end. This squeezes the torsion spring, generating elastic force, which clamps the clamping rod 25 against the outer wall of the dental handpiece for clamping and fixing. A protective plate 26 and a friction pad 27 are installed on the inner wall of the clamping rod 25. The protective plate 26 protects the clamped handpiece air gun, and the friction pad 27 increases the friction between the protective plate 26 and the handpiece air gun, improving the clamping effect of the protective plate 26. A support and fixing pad 28 is installed at the end of the collection bottle 1, allowing the collection bottle 1 to adhere to the table during placement, thus reducing the problem of tilting caused by table shaking. A sealing ring 24 is installed at the bottom of the transparent funnel lid 21, which seals the top of the collection bottle 1 when the transparent funnel lid 21 is covering it.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
