Description

Technical Field

[0001] The utility model relates to the technical field of lung function training, in particular to a lung capacity training device. Background Art

[0002] In modern society, with the accelerated pace of life and increasing work pressure, respiratory health issues are receiving increasing attention. As one of the important indicators for measuring respiratory system function, vital capacity is of great significance for maintaining physical health, improving athletic performance, and assisting in the treatment of respiratory diseases. Traditional vital capacity training methods, such as deep breathing, blowing balloons, or running, can exercise lung function to a certain extent, but often lack precise control and quantitative evaluation, making it difficult to measure the training effect and difficult to adapt to the personalized needs of different groups of people.

[0003] Therefore, lung capacity training equipment has appeared on the market. It is usually made of transparent material. By blowing air, the small ball inside the device floats and can be observed. However, although this type of equipment is designed to be transparent, when blowing air, a large amount of mist will be generated inside it, and even the small ball inside will be blocked, affecting the accuracy and convenience of observation. Utility Model Content

[0004] The purpose of the present invention is to provide a lung capacity training device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] An air blowing nozzle, the material of which includes but is not limited to medical silicone;

[0011] The connecting pipe is provided with circular interfaces at both ends, and the two circular interfaces are matched with the adjustment base and the blowing nozzle respectively.

[0012] Preferably, the outer wall of the transparent tube is symmetrically provided with two groups of scale lines with the connecting rod as the center.

[0013] Furthermore, the outer wall of the transparent tube at the bottom is provided with a thread groove 1.

[0014] Furthermore, the blowing nozzle includes shell one and shell two, and the shell one and shell two are plugged into each other. The end side of the shell one away from the shell two is provided with a cylindrical interface, and the cylindrical interface matches one of the circular interfaces of the connecting pipe. The end side of the shell two away from the shell one is provided with an elliptical interface, and the outer wall of the shell one close to the shell two is provided with a strip groove.

[0015] Further, the adjustment base includes:

[0016] A connecting seat, wherein the inner wall of the connecting seat near the top is provided with a second thread groove, the second thread groove matches the first thread groove. An air inlet is provided on the outer wall of the connecting seat;

[0017] The inner wall of the rotating sleeve is rotatably connected to the outer wall of the connecting seat, and the outer wall of the rotating sleeve is provided with a plurality of circular notches at equal angles;

[0018] The outer cover shell is sleeved on the outer wall of the rotating sleeve. The inner wall of the outer cover shell at the top is fixedly connected to the outer wall of the connecting seat.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Through the coordinated arrangement among the transparent cylinder, scale lines, piston plate, support rod, return spring, connecting plate, connecting rod and observation block, and the flush position of the piston plate and return spring, when the piston plate moves upward along the inner wall of the transparent cylinder by blowing, the observation block located outside the transparent cylinder will also move accordingly, so that the user does not need to observe the internal situation through the mist, but can directly observe the corresponding vital capacity value through the moving observation block, which greatly improves the accuracy and convenience of measurement.

[0023] 2. By screwing the transparent cylinder and the adjustment base together, the air blowing nozzle is set as a detachable shell 1 and shell 2, so that the device is easy to disassemble and clean. Then, by distributing circular notches of successively smaller sizes in an annular array on the outer wall of the rotating sleeve, the rotating sleeve can be rotated to selectively make several circular notches of different sizes correspond to the air inlet, thereby adjusting the resistance.

A return spring 230 is fixedly connected between the inner top surface of the transparent cylinder 100 and the top surface of the piston plate 210. The end of the support rod 220 extending from the top surface of the transparent cylinder 100 is fixedly connected to Connecting plate 240, the bottom surface of the connecting plate 240 is fixedly connected to a connecting rod 250, the bottom end of the connecting rod 250 is fixedly connected to an observation block 260, the connecting rod 250 is slidably plugged into the inside of the limit ring 120, the adjustment base 300 is set on the bottom surface of the transparent tube 100, and the transparent tube 100 can be placed stably on the table, the material of the blowing nozzle 400 includes but is not limited to medical silicone, and circular interfaces are respectively provided at both ends of the connecting tube 500, and the two circular interfaces are respectively matched with the adjustment base 300 and the blowing nozzle 400, and the outer wall of the transparent tube 100 is symmetrically provided with two groups of scale lines 110 with the connecting rod 250 as the center.

[0033] When the air is blown, the piston plate 210 is driven downwards by the rebound force of the return spring 230, thereby returning the observation block 260 to its original position.

[0034] like Figure 3-5As shown, in this embodiment, the outer wall of the transparent tube 100 at the bottom is provided with a thread groove 130, the adjustment base 300 includes a connecting seat 310, the inner wall of the connecting seat 310 near the top is provided with a thread groove 2 312, the thread groove 2 312 matches the thread groove 130, the outer wall of the connecting seat 310 is provided with an air inlet 311, the outer wall of the connecting seat 310 is connected to the rotating sleeve 320, the outer wall of the rotating sleeve 320 is provided with a plurality of circular notches 321 at equal angles, and the rotating sleeve 310 is provided with a plurality of circular notches 321 at equal angles. The outer wall of 20 is sleeved with an outer cover shell 330, and the inner wall of the outer cover shell 330 at the top is fixedly connected to the outer wall of the connecting seat 310. An air inlet interface 331 is provided at a position on the outer wall of the outer cover shell 330 corresponding to the air inlet 311.

Several circular grooves 321 are distributed in a circular array on the outer wall of the rotating sleeve 320, and the sizes of the several circular grooves 321 are reduced successively. A protrusion 322 is fixedly connected to the bottom surface of the rotating sleeve 320.

[0035] In this embodiment, the thread groove 130 and the thread groove 2 312 match, so that the transparent tube 100 and the adjustment base 300 are screwed together for easy disassembly and installation.

By replacing the circular grooves 321 of different sizes and aligning them with the air inlet 311, the resistance can be adjusted. When the size of the selected circular groove 321 is larger, the resistance to blowing is smaller. When the size of the circular groove 321 is smaller, the resistance to blowing is greater.

The shape of the elliptical interface 421 is more suitable for the oral cavity. Compared with the traditional mask-type air nozzle, it is more convenient to blow gas into the transparent tube 100. Shell 1 410 and shell 2 420 are detachable, and the two can be snapped apart from the strip groove 412, making it easier to clean the inside of the blowing nozzle 400.
