Description

Technical Field

[0001] The present invention relates to the technical field of health care equipment, and in particular to a micro-pressure oxygen chamber system that takes into account both positive and negative pressure dual-mode oxygen inhalation. Background Art

[0002] The micro-pressure oxygen chamber is a health care equipment that supplies rich oxygen after being pressurized. As the air pressure in the cabin increases, the oxygen partial pressure in the air also increases, the physical dissolved oxygen in the blood and tissues increases, the alveolar oxygen partial pressure increases significantly, the oxygen permeability increases, the blood oxygen content increases, and the blood oxygen diffusion effect restores cell vitality, quickly eliminates sports fatigue, and effectively improves the body's antioxidant capacity.

[0003] According to the size of the internal pressure compared to the external pressure, it is divided into positive pressure type and external pressure type. The positive pressure type is the cabin pressurization, the pressure is greater than the atmospheric pressure, while the negative pressure type is the cabin decompression, the pressure is lower than the atmospheric pressure. Due to the different working modes, the force directions of the sealed doors are completely opposite, so there is currently no micro-pressure oxygen chamber that takes into account both pressure modes. This is because the swing door design of the inner and outer double doors means that the internal door can only be opened inward, and the internal space of the micro-pressure oxygen chamber is very limited, which will greatly occupy the internal space. At the same time, because the micro-pressure oxygen chamber is closed inside, it will amplify the noise generated by the boost oxygen host and oxygen supply, which will bring a bad experience to customers.

DETAILED DESCRIPTION

[0024] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1-9 As shown:

[0026] A micro-pressure oxygen chamber system that takes into account both positive and negative pressure dual-mode oxygen inhalation, includes a cabin 11, a pressure-boosting oxygen host 4 and a display control screen, the oxygen supply pipe 41 and the air pipe 42 of the pressure-boosting oxygen host 4 are respectively connected to the interior of the cabin 1, the display control screen is installed one inside and one outside the cabin 1, and is electrically connected to the pressure-boosting oxygen host 4 and the sensor integrated module in the cabin 1, a door frame 15 is provided on the side of the cabin 1, sealing strips 151 are installed on the inside and outside of the door frame 15, and a negative pressure sealing door assembly 2 is installed on the outside of the door frame 15, and a positive pressure sealing door assembly 3 is installed on the inside of the door frame 15, and the positive pressure sealing door assembly 3 is installed on the inside of the door frame 15, and the positive pressure sealing door assembly 3 is a sliding structure; a first silencer assembly is installed on the side of the air outlet of the pressure-boosting oxygen host 4, which is connected to the inlet of the oxygen supply pipe 41, and a second silencer assembly is provided inside the cabin 1, which is connected to the outlet of the oxygen supply pipe 41.

[0027] The present invention adopts a double sealing door design. A sliding positive-pressure sealing door assembly 3 is adopted on the inner side of the door frame 15 for sealing during positive-pressure oxygen inhalation. The sliding design can avoid the use of a flat opening method and occupying the space inside the cabin 11. The negative-pressure sealing door assembly 2 arranged on the outer side of the door frame 15 is used for negative-pressure oxygen inhalation. This design enables the present invention to perform oxygen inhalation in both negative-pressure and positive-pressure modes. At the same time, in order to reduce the noise generated during oxygen supply that affects the user experience, the present invention installs a first silencer assembly and a second silencer assembly at both ends of the oxygen supply pipe 41, respectively.

[0028] The first silencer component is a noise reduction box A5, and opposite surfaces of the noise reduction box A5 are respectively provided with an air intake connector A51 and an exhaust connector 52, and the air intake connector A51 is connected to the exhaust pipe 42 of the supercharged oxygen main engine 4; the second silencer component is a noise reduction box B6, and an air intake connector B61 is provided on its side, and a plurality of pneumatic silencers 62 are installed at intervals on the top surface, and the oxygen supply pipe 41 is installed between the exhaust connector 52 and the air intake connector; the noise reduction box A5 and the noise reduction box B6 are both filled with steel wool (the steel wool can be filled in the box body, not shown in the figure).

[0029] The noise is generated because the oxygen generator generates high-frequency vibration and noise, which will be transmitted to the micro-pressure oxygen chamber along with the oxygen, thereby forming a larger noise in the micro-pressure oxygen chamber. Secondly, when the oxygen is directly discharged into the micro-pressure oxygen chamber, the airflow is concentrated and the flow rate is too high, which will also generate noise, greatly affecting the product experience. By filling steel wool in the noise reduction box A5 and the noise reduction box B6, when the high-frequency vibrating oxygen flows through the steel wool, the steel wool will also generate high-frequency vibration. The dense steel wires in the steel wool will rub against each other and vibrate autonomously to convert the vibration energy into heat consumption. The pneumatic muffler 62 disperses the discharge of oxygen, increases the discharge surface, and reduces the flow rate, thereby avoiding the "hissing" noise.

[0030] The existing negative pressure type micro-pressure oxygen chamber needs to manually support the sealing door at the initial stage of decompression, so that the door panel A21 presses the sealing strip 151 on the door frame 15. It can only be released after the internal decompression reaches a certain degree and the self-priming closure is completed. In this way, it requires external assistance for operation. In order to facilitate the customer's own single-person operation, the negative pressure sealing door assembly 2 in the present invention includes a door panel A21, one side of the door panel A21 is installed by a hinge 22, and the other side is installed with a door lock 23, and the two ends of the rotating shaft of the door lock 23 are respectively fixed with an outer handle 231 and an inner handle 232, and the opposite side of the outer handle 231 is integrally provided with a fan-shaped clamp 233; an inverted L-shaped buckle 2 is installed on the inner side of the door frame 15 corresponding to the fan-shaped clamp 233 34, the fan-shaped clamp head 233 is screwed into the locking surface 2341 of the inverted L-shaped buckle 234, and the locking surface 2341 is gradually inclined from the bottom to the rear. When decompressing, close the door and turn the inner handle 232 or the outer handle 231. At this time, the shaft drives the fan-shaped clamp head 233 to rotate, and the fan-shaped clamp head 233 is screwed into the locking surface 2341 of the inverted L-shaped buckle 234 from bottom to top, and the locking surface 2341 is gradually inclined from the bottom to the rear. When the fan-shaped clamp head 233 is rotated upward, it will be pushed back and the door panel will be driven to press the door frame 15 to complete the pre-tightening. This design can complete the pre-tightening step using the door lock 23, so that no manual pre-tightening is required in the early stage of decompression, so that single-person operation can be achieved without other personnel.

[0031] Similarly, in order to enable the positive pressure sealing door assembly 3 to slide and be attracted to the door frame 15, the positive pressure sealing door assembly 3 includes an upper slide rail 31, a lower slide rail 33 and a door panel B32, wherein the upper slide rail 31 and the lower slide rail 33 are respectively located at the top and the bottom of the rear side of the door frame 15, and are provided with slide grooves, and guide support assemblies 321 are installed on both sides of the top and the bottom of the door panel, and the guide support assemblies 321 slide or rotate along the slide grooves of the upper slide rail 31 and the lower slide rail 33, respectively, so as to realize the opening and closing of the door panel B32, wherein the slide groove is composed of a straight groove section 311, an inclined groove section 312 and a notch 314. 13, the inclined groove section 312 is connected to the end of the straight groove section 311, and the notch 313 is T-shaped and arranged on the straight groove section 311. The end of the inclined groove section 312 and the position of the notch 313 respectively correspond to the position of the guide support assembly 321 when the door panel B32 is closed (the working process is shown in the figure). When the guide support assembly 321 is respectively located at the end of the inclined groove section 312 and the position of the notch 313, the door panel B32 has the vertical degree of freedom relative to the door frame 15, so that when the cabin body 11 is pressurized, it automatically presses and seals with the sealing strip 151 on the inner side of the door frame 15 to complete the suction.

[0032] Since the micro-pressure oxygen chamber can be used for health care and recovery in addition to medical purposes, with the improvement of living standards, private individuals and some non-medical institutions have also begun to introduce the use of micro-pressure oxygen chambers. However, the previous micro-pressure oxygen chambers are integrated structural designs, which are bulky and difficult to enter the user's home, thus limiting the user group in the market. The present invention improves the cabin, and the cabin is assembled by a number of independent cabin modules 1a. A circle of connecting beams 11 are arranged on the periphery of the assembly surface of the cabin module 1a, and screw holes 12 are evenly opened on the connecting beams 11; a circle of sealing rubber rings 13 are sandwiched between adjacent butt-jointed connecting beams 11, and adjacent connecting beams 11 are fixed by bolts 14 to assemble the cabin modules 1a into a whole (in order to show the internal structure, the attached figure shows the internal skeleton, and the external decorative skin is not shown). In this way, the volume of each module is relatively small, which is convenient for transportation on the one hand, and convenient for entering the room on the other hand. The volume of each cabin module can be put into the elevator and the door, and the cabin can be quickly assembled by bolts after entering in dispersedly, so that some private owners can also enter the house, which increases the customer's choice.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
