Description

Technical Field

[0001] The utility model relates to the technical field of expectoration devices, in particular to a back-knocking vibration expectoration device. Background Art

[0002] Sputum is a liquid secreted after the respiratory tract is irritated. It usually contains mucus, foreign matter, pathogenic microorganisms, inflammatory cells, and necrotic and detached mucosal epithelial cells. If the sputum cannot be coughed up in time, it will block the respiratory tract, affect respiratory function, and cause symptoms such as difficulty breathing, wheezing, and coughing to worsen. However, the elderly, children, and people with lung and tracheal diseases such as chronic obstructive pulmonary disease and bronchiectasis cannot expel sputum in time and need help from outsiders or auxiliary equipment to expel sputum.

[0003] Chinese patent publication number CN 211675300 U discloses an airbag-type back-slapping expectoration device, comprising a cylindrical handle and a back-slapping airbag. A support rod is connected to the interior of the cylindrical handle end. A speed control knob is embedded on the surface of the support rod near the cylindrical handle. A switch control button is embedded on the surface of the support rod above the speed control knob. A control mainboard is disposed inside the support rod and corresponding to the speed control knob and the switch control button.

[0004] The above-mentioned back-slapping phlegm-exorcising device utilizes a small engine to drive an electrically operated vibration motor. The operation of the vibration motor generates forward and backward vibrations, and a hollow palm-shaped air bag is connected to the front to promote phlegm exorcism by vibrating on the patient's back. However, the small engine and vibration motor of the above-mentioned back-slapping phlegm-exorcising device are located in the palm-shaped air bag. When the palm-shaped air bag slaps the patient's back, a certain reaction force will be generated. The reaction force not only acts on the palm-shaped air bag, but also acts on the small engine and vibration motor in the air bag, so that the small engine and vibration motor will be subjected to impact force. After long-term use, the small engine and vibration motor will be damaged due to the impact force, thereby reducing the service life of the small engine and vibration motor. Utility Model Content

[0005] The purpose of the utility model is to provide a back-tapping vibration expectoration device, in which a flat motor drives a driven disk to rotate through an active disk, and the driven disk continuously pushes a fixed disk during rotation, so that the fixed disk drives a hammer block to perform reciprocating motion, thereby achieving tapping of the patient's back. The flat motor is far away from the hammer block, and the reaction force generated when the hammer block taps the patient's back will not act on the flat motor, so as to solve the technical problems raised by the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A back-tapping vibration expectoration device comprises a driven disk, one side of which is symmetrically provided with two top blocks; a fixed disk is provided on the side of the driven disk close to the top blocks, and two arc-shaped blocks are symmetrically provided on the side of the fixed disk close to the top blocks, and the positions of the top blocks correspond to the positions of the arc-shaped blocks;

[0012] As a further technical solution of the present invention, two straps are provided on the side of the back plate close to the hammer block, and the two ends of the two straps are respectively fixedly connected to multiple ends of the back plate; the middle sections of the two straps are fixedly connected with buckles; the multiple ends of the back plate close to the straps are fixedly connected with positioning rods, and the ends of the multiple positioning rods away from the back plate are respectively fixedly connected to multiple buffer blocks.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model comprises a switch electrically connected to the flat motor. When the flat motor is used, the switch is used to turn on the flat motor, and the flat motor drives the active disk to rotate. The active disk drives the driven disk to rotate through multiple active disks. When the driven disk rotates, the top block rotates synchronously until the top block moves to the arc block of the fixed disk, and the top block pushes the arc block, thereby pushing the fixed disk, so that the fixed disk moves in the direction away from the driven disk; the driven disk drives the hammer block to move through the connecting shaft, and the hammer block compresses the spring when moving; the top block then moves away from the arc block, and the push of the top block is lost. The elastic force generated by the spring drives the hammer block to return to its original position, and the fixed disk is also reset synchronously; under the cooperation of the top block and the spring, the hammer block continuously reciprocates, thereby achieving patting the patient's back; the flat motor is far away from the hammer block and is separated by the driven disk, the fixed disk and the active disk. The reaction force generated when the hammer block pats the patient's back will not be transmitted to the flat motor, thereby ensuring stable use of the flat motor and extending the service life of the flat motor.

[0016] 2. In the present invention, the user carries the backboard on his back via a shoulder strap. The multiple buffer blocks on the backboard can not only ensure the stability of the backboard, but also reduce the user's discomfort and enhance the user's experience. The outer shell protects the driven disk, the fixed disk, the active disk and the flat motor, preventing the driven disk, the fixed disk, the active disk and the flat motor from being affected by the external environment, and also preventing people from being hurt by accidental touch. In addition, the multiple heat dissipation slots can promptly discharge the heat generated by the flat motor during operation, preventing the flat motor from being affected by high temperature and extending the service life of the flat motor.
