Description

Technical Field

[0001] The utility model belongs to the technical field of pulse oxygen generators, and more specifically, particularly relates to a pulse oxygen generator with accurate breathing detection. Background Art

[0002] An oxygen concentrator is a type of machine that produces oxygen. It uses air separation technology to compress air at a high density and then uses the different condensation points in the air to separate the gas and liquid, and distill it into oxygen and nitrogen. The pulse oxygen concentrator is different from the traditional oxygen concentrator. It uses a sensor to detect the pressure difference generated by breathing, so that oxygen is supplied during inhalation and oxygen is cut off during exhalation, which greatly improves the oxygen utilization rate and reduces waste. However, the existing pulse oxygen concentrator requires users to adapt to the rhythm of oxygen supply due to inaccurate breathing detection. During the inhalation stage, no oxygen is supplied or insufficient oxygen may occur, making it difficult to accurately detect breathing and pressure difference. The breathing detection component is installed close to the outside, and the air flow generated by the external air can easily affect the detection accuracy. It is difficult to install it at a position closer to the inside for breathing pressure difference detection and easy maintenance or installation. The bottom of the air compressor is protected by springs for shock absorption or buffering. Since the direction can be shaken at will, the air compressor is still likely to be damaged by collision, and it is difficult to reduce the shaking amplitude to achieve a protective effect.

DETAILED DESCRIPTION

[0025] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0026] Embodiment 1:

[0027] As attached Figure 1 To Attachment Figure 7 As shown:

[0028] The utility model provides a pulse oxygen concentrator for accurate breathing detection, comprising a machine body 1; a control panel 101 is arranged on the top of the machine body 1, a molecular sieve 102 and a shock-absorbing base 2 are arranged inside the machine body 1, and a fastener 7 is connected to the inside of the front panel of the machine body 1 through threaded engagement; two groups of connecting plates 3 are clamped on the top of the shock-absorbing base 2; a sliding groove 302 is opened inside the connecting plate 3; a spring seat 4 is slidably clamped inside the sliding groove 302; an air compressor 5 is fixedly installed on the top surface of the spring seat 4; the air outlet end of the air compressor 5 is connected to the top of the molecular sieve 102 through a pipeline; a gas tank is integrally connected between the two groups of molecular sieves 102, and the air outlet end of the molecular sieve 102 is connected to a sensor adjustment member 103 through a pipeline; the sensor adjustment member 10 3 is provided with a pressure reducing valve, an oxygen concentration sensor and a one-way valve for sensing oxygen concentration, regulating oxygen output and controlling oxygen output (this is the prior art, so it is not marked in the figure). The top of the sensor adjustment member 103 is connected to the flow meter 6 through a pipeline; the top of the flow meter 6 is provided with an oxygen outlet pipe, and the end of the oxygen outlet pipe passes through the front panel of the body 1; the inside of the fastener 7 is clamped with a breathing detection member 8; the rear circular tube structure of the breathing detection member 8 is fixedly connected by a connecting rod 802, and a connecting member 9 is clamped between the rear circular tube and the breathing detection member 8, and an air pressure sensor 801 is placed inside the breathing detection member 8, and the air pressure sensor 801, the sensor adjustment member 103 and the air compressor 5 are respectively electrically connected to the circuit integrated controller inside the control panel 101.

[0029] As attached Figure 4 and attached Figure 5 As shown, two sets of rotating plates 701 are welded on the outer wall of the fastener 7, and a limiting slot 702 is provided on the inner wall of the fastener 7. The interior of the limiting slot 702 is penetrated by the connecting member 9. By rotating the rotating plate 701, the fastener 7 can be smoothly installed on the front end of the body 1. At the same time, the connecting member 9 is limited by the limiting slot 702 and fixed to the body 1 synchronously. The fastener 7 adopts a detachable connection method, which is convenient for the inspection or replacement of the respiratory detection component 8.

[0030] As attached Figure 5 and attached Figure 6 As shown, an inner card plate 902 is welded to the inner wall of the connecting member 9, and the inner card plate 902 is clamped in the inner card slot 803. A slot 901 is provided inside the connecting member 9, and a spring plate 903 is inserted in the slot 901. A connecting rod 904 is welded inside the inner card plate 902, and a spring sleeve 905 is sleeved between the two groups of connecting rods 904. A spring is arranged inside the spring sleeve 905, and both ends of the spring are respectively fixedly connected to the inner ends of the two groups of connecting rods 904. When the connecting member 9 is squeezed toward the middle, the inner card plate 90 2 and the connecting rod 904 move toward the middle, compress the spring inside the spring sleeve 905, and at the same time reduce the outer diameter of the connecting piece 9 until the outer diameter of the connecting piece 9 is no larger than the outer diameter of the respiratory detection piece 8, and snap the connecting piece 9 and the respiratory detection piece 8 into the fastener 7 at the same time, push the respiratory detection piece 8 backward until the connecting piece 9 is snapped into the limiting slot 702, and push the connecting rod 904 and the connecting piece 9 to pop out through the spring inside the spring sleeve 905, so that the respiratory detection piece 8 and the fastener 7 are fixedly snapped.

[0031] As attached Figure 3 As shown, the two groups of connecting plates 3 are connected by setting an inner spring connecting sleeve rod 301. The inner spring connecting sleeve rod 301 is a two-stage sleeve rod structure and is connected internally by a spring. When a collision occurs in the left and right directions, the shaking is transmitted to the connecting plate 3 through the shock-absorbing base 2. When the connecting plate 3 shakes left and right, the inner spring connecting sleeve rod 301 is compressed. Through the elastic action of the spring, it is compressed and at the same time generates an outward thrust, thereby offsetting the thrust generated by the connecting plate 3 on it, thereby achieving a shock-absorbing protective effect.

[0032] As attached Figure 3 As shown, a spring is provided on the outside of the spring seat 4, and a connecting rod 401 is movably connected inside the spring seat 4. The top end of the connecting rod 401 is fixedly connected to the bottom surface of the air compressor 5, and the spring seat 4 is movably connected to the inside of the sliding groove 302 in the front-to-back direction. When a collision occurs in the front-to-back or up-to-down direction, the spring on the top of the spring seat 4 is repeatedly compressed and stretched to reduce the shaking amplitude, and the limit between the spring seat 4 and the connecting rod 401 is used to offset the shaking in the front-to-back direction, thereby achieving a protective effect.

[0033] As attached Figure 5and attached Figure 7 As shown, the inner wall of the breathing detection component 8 is provided with an inner card groove 803, and the inner card groove 803 is located on the front and rear sides of the cross section. The inner card groove 803 is used to allow the connecting component 9 to have a maximum outward movement distance, thereby ensuring the sealing connection between the connecting component 9 and the breathing detection component 8. When the breathing becomes weaker, the installation position of the air pressure sensor 801 is deepened, thereby reducing the interference of the air flow outside the body 1 on the air pressure, thereby ensuring the accuracy of the breathing detection.

[0034] As attached Figure 3 As shown, a slot 201 is provided on the top surface of the shock-absorbing base 2, and the connecting plate 3 is movably connected to the left and right directions inside the slot 201. The bottom surface of the shock-absorbing base 2 is welded to the inner bottom surface of the body 1. When the body 1 is hit, it shakes in the left and right directions, and the connecting plate 3 slides in the left and right directions inside the slot 201, thereby reducing damage to the air compressor 5 and playing a protective role.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In the present invention, after squeezing the connecting member 9 toward the middle, the inner clamping plate 902 and the connecting push rod 904 are driven to move toward the middle, compressing the spring inside the spring sleeve 905, and reducing the outer diameter of the connecting member 9 at the same time, until the outer diameter of the connecting member 9 is no larger than the outer diameter of the breathing detection member 8, the connecting member 9 and the breathing detection member 8 are simultaneously clamped into the inside of the fastener 7, and the breathing detection member 8 is pushed backward until the connecting member 9 is clamped into the inside of the limit clamping groove 702, and the connecting push rod 904 and the connecting member 9 are pushed outward by the spring inside the spring sleeve 905, so that the breathing detection member 8 and the fastener 7 are fixedly clamped;

[0037] The rotating plate 701 allows the fastener 7 to be smoothly installed on the front end of the body 1, and the installation of the breathing detection component 8 is completed at the same time. When the user breathes, the pressure difference at both ends of the breathing detection component 8 is sensed by the air pressure sensor 801, and the sensor adjustment component 103 and the flow meter 6 are started. While outputting oxygen to the outside, the oxygen concentration and flow are displayed on the display screen of the control panel 101.

[0038] Embodiment 2, based on embodiment 1, as shown in the attached Figure 6 As shown, the outer wall of the spring plate 903 is provided with an outer slot 9031, and the inner part of the outer slot 9031 is connected to the connecting rod 802. The two ends of the spring plate 903 are integrally provided with plug rods 9032, and the plug rods 9032 are inserted into the slot 901. When the connecting member 9 is pressed inward, the spring plate 903 is bent through the slot 901 and the plug rod 9032, thereby reducing the outer diameter. When the connecting member 9 is released, the spring plate 903 is reset by its own elastic action, and at the same time, the auxiliary spring sleeve 905 makes the connecting member 9 spring outward, so that it is clamped into the inside of the limit slot 702 to achieve a fixed connection.
