Description

Technical Field

[0001] The present invention relates to the technical field of expectoration machines, and more particularly to a transmission flexible shaft and a vibrating expectoration machine based thereon. Background Art

[0002] A vibrating expectorant uses vibration to loosen sputum and facilitate coughing. The power of the vibrating expectorant is transmitted to the treatment head via a flexible shaft. The flexible shaft consists of a connecting sleeve, a flexible shaft sleeve, and a flexible shaft body. The flexible shaft body inside the flexible shaft sleeve is susceptible to wear and tear on the connecting sleeve connected to the instrument during rotation. This poses a risk of rupture with long-term use, which can affect the lifespan of the flexible shaft. Summary of the Invention

[0003] The purpose of the present invention is to provide a transmission flexible shaft and a vibrating expectorant based thereon, so as to solve the technical problems existing in the above-mentioned background technology.

[0004] The technical solution of the present invention provides a transmission flexible shaft, comprising a connecting sleeve, a flexible shaft sleeve, and a flexible shaft body passing through the connecting sleeve and the flexible shaft sleeve, wherein a reinforcement sleeve and a protective component fixedly connected to the reinforcement sleeve and arranged inside the reinforcement sleeve are arranged in the connecting sleeve, and the flexible shaft body passes through the protective component;

[0005] The protection component includes two bearings arranged at intervals, and the two bearings are respectively arranged close to the two ends of the connecting sleeve.

[0006] In a preferred embodiment, two slots are provided on both sides of the connecting sleeve, which are respectively plugged and fixed with the instrument and the flexible sleeve. A plug connector is provided at one end of the flexible sleeve, and the plug connector is inserted into the slots.

[0007] In a preferred embodiment, the flexible shaft sleeve includes an outer plastic soft sleeve and an inner metal soft sleeve, and the flexible shaft body is arranged through the inner metal soft sleeve.

[0008] In a preferred embodiment, the reinforcement sleeve is a metal sleeve.

[0009] A vibrating expectorant comprises the above-mentioned flexible transmission shaft.

[0010] The beneficial effects of the technical solution of the present invention are:

[0011] The flexible shaft body passes through the bearing, and two bearings are set to limit the flexible shaft body so that the flexible shaft body will not contact the connecting sleeve during rotation, thereby protecting the connecting sleeve, avoiding wear of the connecting sleeve, and extending the service life of the connecting sleeve.

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and convenience of description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0018] like Figure 1-4 As shown, the technical solution of the present invention provides a transmission flexible shaft, including a connecting sleeve 1, a flexible shaft sleeve 2, and a flexible shaft body 3 that passes through the connecting sleeve 1 and the flexible shaft sleeve 2. One end of the flexible shaft body 3 is connected to the transmission assembly on the instrument, and the other end is connected to the treatment head to achieve power transmission. The connecting sleeve 1 facilitates the connection of the entire transmission flexible shaft to the instrument end, and the flexible shaft sleeve 2 wraps and protects the flexible shaft body 3.

[0019] The connecting sleeve 1 is provided with a reinforcement sleeve 11 and a protective assembly disposed within the reinforcement sleeve 11 and fixedly connected to the reinforcement sleeve 11. The flexible shaft body 3 is disposed through the protective assembly. The reinforcement sleeve 11 is a metal sleeve that serves to enhance the overall strength of the connecting sleeve 1 while facilitating the installation of the bearing 12. During rotation, the flexible shaft body 3 generates friction with the interior of the connecting sleeve 1. Over time, the interior of the connecting sleeve 1 may wear and tear, potentially leading to rupture. Therefore, the protective assembly is provided to protect the interior of the connecting sleeve 1 and extend its service life.

[0020] The protective assembly includes two bearings 12 spaced apart, and the two bearings 12 are respectively arranged near the two ends of the connecting sleeve 1. The flexible shaft body 3 passes through the bearings 12. The two bearings 12 are provided to limit the flexible shaft body 3 so that the flexible shaft body 3 does not contact the connecting sleeve 1 during rotation, thereby protecting the connecting sleeve 1 and preventing wear of the connecting sleeve 1.

[0021] The connecting sleeve 1 is provided with two slots 13 on both sides for respectively plugging and fixing with the instrument and the flexible sleeve 2. A plug connector 23 is provided at one end of the flexible sleeve 2, and the plug connector 23 is inserted into the slots 13. The slots 13 facilitate the connection of the connecting sleeve 1 with the instrument and the flexible sleeve 2, and are also easy to disassemble.

[0022] The flexible shaft sleeve 2 includes an outer plastic soft sleeve 21 and an inner metal soft sleeve 22, and the flexible shaft body 3 is arranged through the inner metal soft sleeve 22. The inner metal soft sleeve 22 has a protective effect on the outer plastic soft sleeve 21 to prevent the outer plastic soft sleeve 21 from being worn.

[0023] A vibrating expectorant comprises the above-mentioned flexible transmission shaft.

[0024] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
