Description

Technical Field

[0001] The utility model relates to the technical field of oxygen supply therapy equipment, in particular to a micro-hyperbaric oxygen chamber. Background Art

[0002] With the development of modern medical technology and the improvement of people's living standards, oxygen therapy has become a common method to improve physical functions. Especially in some scenarios where physical and mental strength needs to be restored quickly, such as athletes recovering after training, health care for the elderly, and people with related diseases, the need for oxygen therapy is increasing.

[0003] The emergence of micro-hyperbaric oxygen chambers has well met people's needs for oxygen therapy. Its working principle is to place people in a closed cabin, provide high-purity oxygen to the interior and maintain a stable air pressure. Usually the cabin is pressurized to 1.1-1.3 standard atmospheric pressures. Hyperbaric oxygen can greatly increase the dissolved oxygen in the plasma, thereby ensuring the normal operation of cells and promoting blood oxygenation, thereby relieving fatigue and symptoms of some diseases.

[0004] The applicant believes that the current micro-hyperbaric oxygen chamber has the following defects during use: First, when a person enters the oxygen chamber, he needs to use his hands to continuously push the door from the inside to the outside, so as to press the door against the door frame to achieve a preliminary seal and provide necessary protection for pressurizing the chamber. When the pressure in the oxygen chamber increases to a level that can force the door to automatically press against the door frame under the pressure, the person can stop pushing the door. The above-mentioned process of pushing the door lasts for a long time and requires a lot of physical strength, resulting in a poor user experience. Second, when the micro-hyperbaric oxygen chamber is placed in a family for use, children often enter the chamber privately. Due to the children's activeness, it is very easy for them to lock the door from the inside of the oxygen chamber after closing the door, thereby trapping the children in the oxygen chamber, which poses certain safety hazards. In view of this, it is necessary for the applicant to provide a micro-hyperbaric oxygen chamber with a good user experience and the ability to prevent children from accidentally locking the door. Utility Model Content

Based on this, the present invention provides a micro-hyperbaric oxygen chamber with a strong user experience and high safety.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a micro-hyperbaric oxygen chamber, comprising a chamber body and a chamber door, the chamber door is rotatably mounted on the chamber body to close the inlet and outlet of the chamber body, a sealing strip is arranged around the inlet and outlet on the chamber body, an annular cavity is arranged in the sealing strip, and the chamber door can press against the sealing strip when it is closed, a pressurization hole is arranged on the chamber body, the annular cavity and the pressurization hole are both connected to a pressurization pump, an oxygen storage tank is connected to the chamber body, a slider is slidably arranged on the chamber body at one side of the chamber door, a limit block is rotatably arranged on the slider, a baffle is fixedly connected to the limit block, a limit groove matched with the limit block is arranged on the chamber body, and after the limit block is rotated to align with the limit groove, the slider is slid along the limit groove so that the baffle can be pressed on the chamber door.

[0007] Furthermore, an annular installation groove is provided on the inner wall of the cabin body around the inlet and outlet, the sealing strip is fixedly installed in the installation groove, and an annular ridge is provided on the surface of the cabin door facing the inlet and outlet corresponding to the installation groove, and the cross-section of the ridge is an arc-shaped structure.

[0008] Furthermore, a slide groove is provided on the inner wall of the cabin body in a horizontal direction, and the sliding block cooperates with the slide groove and is slidably installed in the slide groove.

[0009] Furthermore, a limiting member is protrudingly provided on the inner wall of the cabin on both sides of the slide groove, and the limiting member includes a horizontal plate and a vertical plate, one side of the horizontal plate is fixedly connected to the inner wall of the cabin, and the other side of the horizontal plate is fixedly connected to the vertical plate, and the sliding block is in contact with the surface of the vertical plate facing the slide groove.

[0010] Furthermore, the space sandwiched between the two longitudinal plates constitutes the limiting groove, the limiting block is in a waist-shaped structure, and two opposite planes on the limiting block can fit with the groove wall of the limiting groove.

[0011] Furthermore, the length of the limiting block is greater than the width of the limiting block.

[0012] Furthermore, a rotation space for the limit block to rotate is formed on the end of the slide groove located at the limit piece.

[0013] Furthermore, the baffle is located outside the limiting groove.

[0016] The beneficial effects of the utility model are as follows: the micro-hyperbaric oxygen chamber of the utility model first places the door against the inlet and outlet, and locks it to the cabin body through the baffle, and then pressurizes the sealing strip. After the sealing strip expands, it is tightly pressed against the door, realizing the sealing function of the door before pressurizing the cabin body, and the user does not need to continuously push the door, which greatly saves manpower and improves the user experience. At the same time, the locking operation of the door is completed by rotating and sliding, which increases the difficulty of accidentally locking the door for children, thereby effectively preventing children from accidentally locking the door, eliminating safety hazards, and making it safer to use and easy to promote.

DETAILED DESCRIPTION

[0026] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0027] See also Figure 1-Figure 7 The utility model provides a micro-hyperbaric oxygen chamber, comprising a chamber 1 and a door 2 installed on the chamber 1. The chamber 1 is a hollow box structure, and an inlet and outlet 11 are provided on the side wall of the chamber 1. One side of the door 2 is rotatably installed inside the chamber 1. A sealing strip 3 is fixedly installed along the edge of the inlet and outlet 11 on the inner wall of the chamber 1. A hollow annular cavity 31 is provided in the sealing strip 3. When the door 2 is closed, the sealing strip 3 can be pressed against. A pressurizing hole 12 is provided on the side wall of the chamber 1. The annular cavity 31 and the pressurizing hole 12 are connected to a booster pump 4 through a pipeline. An oxygen storage tank (not shown in the figure) is connected to the chamber 1. An air compressor (not shown in the figure) is installed on the oxygen storage tank for controlling the filling of oxygen into the chamber 1. A slider 6 is slidably provided on the cabin body 1 at one side of the cabin door 2, a limit block 7 is rotatably provided on the slider 6, a baffle 8 is fixedly connected to the limit block 7, and a limit groove 13 cooperating with the limit block 7 is provided on the cabin body 1. After the limit block 7 is rotated to align the limit block 7 with the limit groove 13, the slider 6 is slid along the limit groove 13 to press the baffle 8 on the cabin door 2.

[0028] The micro-hyperbaric oxygen chamber of the utility model is used in the following process: the user enters the interior of the cabin body 1 through the inlet and outlet 12, then rotates the cabin door 2 from the inside, so that the cabin door 2 presses against the sealing strip 3; then, the limit block 7 is rotated to drive the baffle 8 to rotate together, and the baffle 8 is adjusted to a horizontal state. At this time, the limit block 7 is aligned with the limit groove 13. When the slider 6 is slid, the limit block 7 can be driven to move along the limit groove 13 to the side close to the cabin door 2, so that the baffle 8 moves to the side of the cabin door 2 away from the inlet and outlet 11, and the baffle 8 is at least partially opposite to the cabin door 2 and presses against the cabin door 2. Then, the booster pump 4 is controlled to first increase the pressure in the annular cavity 31 of the sealing strip 3. After the pressure in the annular cavity 31 is increased, the sealing strip 3 will press the cabin door 2 against the baffle 8 due to outward expansion, thereby achieving the sealing between the cabin door 2 and the cabin body 1. When the sealing between the hatch door 2 and the cabin body 1 is completed, the boosting pump 4 is controlled to increase the pressure in the cabin body 1. As the pressure in the cabin body 1 continues to increase, the hatch door 2 gradually moves outward under the action of the cabin pressure and is further pressed against the sealing strip 3, thereby further improving the sealing between the hatch door 2 and the cabin body 1. It can be understood that the greater the internal pressure of the cabin body 1, the better the sealing at the hatch door 2.

[0029] The micro-hyperbaric oxygen chamber of the utility model can not only seal the cabin door 2, but also prevent children from accidentally locking the cabin door 2 from the inside. Specifically, when the cabin door 2 needs to be locked, the limit block 7 needs to be rotated relative to the slider 6 so that the limit block 7 is aligned with the limit groove 13, and then the limit block 7 can be slid along the limit groove 13 to move the baffle 8 to the position of the cabin door 2 and press it on the cabin door 2. The above operation process needs to be completed by rotating and sliding in sequence, which increases the difficulty of accidentally locking the cabin door 2 for children, thereby effectively preventing children from accidentally locking the cabin door 2.

[0030] See also Figure 4 As a preferred embodiment, an annular mounting groove 14 is provided on the inner wall of the cabin body 1 around the inlet and outlet 11, and the sealing strip 13 is fixedly installed in the mounting groove 14. The mounting groove 14 is used to install and fix the sealing strip 13 on one hand, and can also play a certain guiding role in the deformation of the sealing strip 3 when the pressure inside the annular cavity 31 increases, so that the sealing strip 3 can be pressed against the cabin door 2 as much as possible after expansion. An annular convex ridge 21 is convexly provided on the surface of the cabin door 2 facing the inlet and outlet 11 corresponding to the mounting groove 14, and the convex ridge 21 forms a closed circle corresponding to the mounting groove 14, and the cross section of the convex ridge 21 is an arc-shaped structure. When the cabin door 2 is closed, the sealing strip 3 after pressurization and expansion can be in close contact with the convex ridge 21, and the convex ridge 21 with an arc-shaped cross section can increase the mutual extrusion area between the convex ridge 21 and the sealing strip 13, thereby improving the sealing performance and making the sealing more reliable. Further, the sealing strip 13 is made of sealing materials such as silicone or rubber.

[0031] Also, see Figure 7, the cabin body 1 is connected with a first pipe 15 and a second pipe 16, the first pipe 15 is connected with the annular cavity 31, the second pipe 16 is connected with the boosting hole 12, the boosting pump 4 is connected with a third pipe 41, and a three-way valve 9 is connected between the first pipe 15, the second pipe 16 and the third pipe 41. In this embodiment, the three-way valve 9 is a one-inlet and two-outlet three-way solenoid valve. Among them, the first pipe 15 and the second pipe 16 are connected with the two outlets of the three-way valve 9, and the third pipe 41 is connected with the inlet of the three-way valve 9. In this way, when working, when the solenoid valve coil is energized, the annular cavity 31 is charged with pressure through the first pipe 15, and the second pipe 16 is closed; when the solenoid valve coil is de-energized, the cabin body 1 is charged with pressure through the second pipe 16, and the first pipe 15 is closed. Furthermore, a sealed pressure relief valve 17 connected to the annular cavity 31 is installed on the cabin 1 for relieving pressure in the annular cavity 31; an emergency pressure relief valve 18 is installed inside the cabin 1, and the emergency pressure relief valve 18 is for user operation. When the user feels uncomfortable and needs pressure relief, the emergency pressure relief valve 18 can be operated to quickly release the pressure in the cabin 1 to the outside of the cabin 1.

[0032] As a preferred embodiment, one side of the hatch 2 is connected to the inner wall of the cabin body 1 via a hinge 10 to achieve the opening and closing action of the hatch 2.

[0033] See also Figure 6 As a preferred embodiment, a slide groove 101 is provided on the inner wall of the cabin 1 in the horizontal direction. The slide groove 101 and the limiting groove 13 are parallel to each other. The slider 6 cooperates with the slide groove 101 and is slidably installed in the slide groove 101. Limiting members 102 are convexly provided on both sides of the slide groove 101 on the inner wall of the cabin 1. The cross section of the limiting member 102 is an L-shaped structure. The limiting member 102 includes a horizontal plate 1021 and a vertical plate 1022. One side of the horizontal plate 1021 is fixedly connected to the inner wall of the cabin 1, and the other side of the horizontal plate 1021 is fixedly connected to the vertical plate 1022. The slider 6 is in contact with the surface of the vertical plate 1022 facing the slide groove 101. In this way, the slider 6 and the slide groove 101 can be restricted from being separated from each other.

[0034] Furthermore, the space sandwiched between the two longitudinal plates 1022 constitutes the limiting groove 13, and the limiting block 7 is in an oval shape. The two opposite planes on the limiting block 7 can fit with the groove wall of the limiting groove 13, so that the limiting block 7 slides along the limiting groove 13. It should be noted that the length of the limiting block 7 (i.e., the distance between the two arc-shaped surfaces on the limiting block 7) is greater than the width of the limiting block 7 (i.e., the distance between the two planes on the limiting block 7). In this way, only when the limiting block 7 rotates to a horizontal position relative to the slider 6 and is aligned with the limiting groove 13, the limiting block 7 can slide into the limiting groove 13, while the limiting block 7 at other positions cannot enter the limiting groove 13, thus preventing the baffle 8 from locking the cabin door 2 on the cabin body 1.

[0035] In addition, a rotation space 1011 is formed on the slide groove 101 at the end of the limit member 102. When the slider 6 is slid to drive the limit block 7 to move into the rotation space 1011, the limit block 7 is disengaged from the limit groove 13, and the rotation space 1011 can be used for the limit block 7 to rotate.

[0036] Furthermore, the baffle plate 8 is located outside the limiting groove 13 to prevent the baffle plate 8 from interfering with the limiting member 102 , thereby preventing the limiting block 7 from rotating in the rotation space 1011 .

[0037] As a preferred embodiment, a pin shaft 61 is fixedly mounted on the slider 6 , and the limit block 7 is rotatably sleeved on the outside of the pin shaft 61 . In a specific implementation, a bearing is provided between the limit block 7 and the pin shaft 61 .

[0038] In this embodiment, the cabin door 2 is made of transparent glass material, which is convenient for outsiders to observe the status of the user in the cabin 1.

[0039] As a preferred embodiment, a human-machine interactive display screen 19 is also installed on the inner wall of the cabin 1. The human-machine interactive display screen 19 is a touch screen. The human-machine interactive display screen 19 can display the oxygen cabin operation information including air pressure and oxygen content inside the cabin 1, so that the user can adjust and control the cabin environment. In addition, an oxygen sensor for monitoring the oxygen content in the cabin and a pressure sensor for monitoring the air pressure in the cabin are installed in the cabin 1.

[0040] The micro-hyperbaric oxygen chamber of the utility model first places the door 2 against the inlet and outlet 11, and locks it on the cabin body 1 through the baffle 8, and then pressurizes the sealing strip 3. After the sealing strip 3 expands, it is tightly pressed against the door 2, realizing the sealing function of the door 2 before pressurizing the cabin body 1. The user does not need to continuously push the door 2, which greatly saves manpower and improves the user experience. At the same time, the locking operation of the door 2 is completed by rotating and sliding, which increases the difficulty of accidentally locking the door 2 for children, thereby effectively preventing children from accidentally locking the door 2, eliminating safety hazards, and making it safer to use and easy to promote.

[0041] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
