Description

Technical Field

[0001] The invention relates to the field of disinfection and sterilization of dental equipment, in particular to a protective cover used for disinfection and sterilization of dental mobile phones. Background Art

[0002] Dental handpieces are commonly used tools in dental clinics. They have drive components and rotating parts. To ensure the normal operation of the components, lubricating oil is added to the rotating parts. Dental handpieces need to be disinfected and sterilized after use. The sterilization method is 134℃ pre-vacuum pressure steam sterilization.

[0003] However, during the sterilization of dental handpieces, the lubricating oil inside the handpiece may overflow during the vacuum process (the amount of lubricating oil inside the dental handpiece is not large, so no large amount of spraying will occur). The overflowing lubricating oil will soak into the paper-plastic sterilization bag that packages the dental handpiece, thereby contaminating the sterilization bag and causing the entire sterilization process to fail to meet the requirements. At the same time, the bearing at the end of the dental handpiece is easily damaged by collision.

[0004] To overcome the above-mentioned shortcomings, the existing method is to wrap the upper and lower ends of the dental handpiece (the parts where lubricating oil may overflow) with paper. However, this method has the following disadvantages: it increases the workload of the operator. If the amount is large, the operator cannot handle it in time, and paper is wasted. At the same time, the paper is opaque, which affects the user's choice of handpiece type. Summary of the Invention

[0005] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a device with reasonable design, simple structure and easy use for disinfecting dental mobile phones, which solves the problem of lubricating oil contaminating the sterilization bag during the disinfection of dental mobile phones. Through the reasonable design of the sleeve, the sleeve is installed at the upper end and / or lower end of the dental mobile phone to prevent the lubricating oil of the dental mobile phone from contaminating the sterilization bag. At the same time, an oil baffle ring is provided on the inner wall of the sleeve, and the oil baffle ring and the inner wall of the sleeve form an oil collecting area. Under the obstruction of the oil collecting area and the oil baffle ring, the lubricating oil can be prevented from overflowing from the sleeve.

[0006] The present invention is achieved by constructing a dental handpiece protective cover, which includes a cover body with one end open and the other end closed. An oil deflector ring extending inward and tilted toward the inner bottom is provided on the inner wall of the cover body near the open end, and the oil deflector ring and the inner wall form an oil collection area.

[0007] Preferably, the inner wall of the open end of the sleeve body is provided with a plurality of radially extending stabilizing teeth.

[0008] Preferably, the radial extension distance of the stabilizing teeth from the inner wall of the sleeve is greater than the radial extension distance of the oil deflector ring from the inner wall of the sleeve.

[0009] Preferably, the inner wall of the sleeve is provided with a plurality of guide grooves extending toward the open end and converging into the oil collecting area.

[0010] Preferably, the sleeve is integrally formed of a transparent soft material. The transparent sleeve makes it easy for dental handpiece users to distinguish between types of dental handpieces, allowing them to quickly select a suitable dental handpiece. The sleeve is made of soft material, which makes it easy for the protective cover to be installed on the head or tail of the handpiece and is also easy to disassemble. The sleeve made of soft material can play a protective role. When the dental handpiece collides, the soft sleeve can buffer the dental handpiece, reducing the risk of damage to internal components of the dental handpiece due to collision.

[0011] Preferably, the outer wall of the sleeve is a frosted surface, which can increase friction and make installation and disassembly more convenient.

[0012] The present invention has the following beneficial effects:

[0013] The present invention has a reasonable design, a simple structure, and is easy to use. The protective cover for dental handpiece disinfection solves the problem of lubricating oil contaminating the sterilization bag during dental handpiece disinfection. The cover is reasonably designed and mounted on the upper end and / or lower end of the dental handpiece to prevent the lubricating oil of the dental handpiece from contaminating the sterilization bag. At the same time, an oil baffle ring is provided on the inner wall of the cover. The oil baffle ring and the inner wall of the cover form an oil collecting area. Under the obstruction of the oil collecting area and the oil baffle ring, the lubricating oil can be prevented from overflowing from the cover.

[0014] At the same time, a reasonable arrangement of stabilizing teeth is provided on the inner wall of the sleeve, which can ensure that the sleeve is stably mounted on the dental handpiece and can solve the problem of preventing it from falling off;

[0015] In addition, a guide groove is reasonably provided on the inner wall of the sleeve, which extends along the open end and gathers in the oil collection area, and can guide the lubricating oil overflowing from the mobile phone dental to the oil collection area, so as to make its protection effect better and prevent the lubricating oil from overflowing everywhere.

[0016] The present invention has an ingenious structure, is easy to install and disassemble, and is made of soft transparent material, which makes it easy for dental mobile phone users to choose the type of dental mobile phone. At the same time, the soft material can play a buffering role, reducing the risk of bearing damage when the dental mobile phone collides. It is low in cost and has good use effect, which reduces the labor intensity of workers during disinfection and improves their work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the Figure 1-Figure 7 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Embodiment 1 (optimum embodiment),

[0027] like Figure 1-Figure 5 As shown, a dental handpiece protective cover comprises a cover body 1 which is open at one end and closed at the other end. An oil deflector ring 2 which extends inward and tilts toward the inner bottom is provided on the inner wall of the cover body near the open end. The oil deflector ring and the inner wall form an oil collecting area 2.1.

[0028] In this embodiment, the inner wall of the open end of the sleeve body 1 is provided with a plurality of radially extending stabilizing teeth 3 .

[0029] In this embodiment, the radial extension distance of the stabilizing teeth 3 from the inner wall of the sleeve is greater than the radial extension distance of the oil deflector ring 2 from the inner wall of the sleeve, so that the stabilizing teeth fit against the outer wall of the mobile phone while the oil deflector ring does not contact the outer wall of the mobile phone.

[0030] In this embodiment, the inner wall of the casing 1 is provided with a plurality of guide grooves 4 extending toward the open end and converging into the oil collecting area.

[0031] In this embodiment, the sleeve body 1 is integrally formed of a transparent soft material.

[0032] In this embodiment, the outer wall of the sleeve body 1 is a frosted surface.

[0033] like Figure 6-Figure 7As shown, when the present invention is in use, the sleeve 1 is installed on the upper end and / or lower end of the dental handpiece 5 to prevent the lubricating liquid in the dental handpiece from overflowing into the sterilization bag when the dental handpiece is disinfected. When installing the present invention, the end or tail of the dental handpiece is inserted from the open end of the sleeve, and the mouth with overflowing liquid is put into the sleeve through the sleeve and fixed by the stabilizing teeth. The inner wall of the stabilizing teeth fits with the outer wall of the clamping handpiece to achieve the stability of the sleeve and prevent the sleeve from slipping. When the dental handpiece with a protective sleeve overflows lubricating liquid, the lubricating liquid will overflow on the inner wall of the sleeve, or be collected in the oil collection area through the guide groove. Under the action of the oil retaining ring, the lubricating liquid is guaranteed not to overflow the protective sleeve, thereby ensuring that the sterilization bag will not be contaminated by the lubricating oil.
