Description

Technical Field

[0001] This utility model relates to the field of portable oxygen tank technology, and in particular to a breathing mask suitable for portable oxygen tanks. Background Technology

[0002] A portable oxygen cylinder is an oxygen cylinder that can be carried around. It uses a pressurizing device to compress oxygen into the cylinder, forming a small device. It is characterized by its small size, large capacity, portability, and high concentration of pure oxygen. Generally, portable oxygen cylinders are filled with oxygen with a purity of over 95%, making them convenient for emergency treatment and daily health care. For example, after long hours of work or strenuous physical exertion, a portable oxygen cylinder can be used to replenish oxygen, allowing the body to replenish energy and restore physical strength.

[0003] Patent No. 202222297529.7 discloses a comfortable oxygen inhalation mask for a portable oxygen tank, including a mask body, a valve control mechanism for controlling the opening or closing of the oxygen tank valve, and an oxygen slow-flow box for oxygen delivery. The mask body includes an oxygen delivery mask that can fit against the face of the user during use, a mounting sleeve that can be installed on the top of the oxygen tank, and a mask body positioning plate with a circular plate structure located in the middle of its inner cavity. The valve control mechanism is connected to the end of the mask body positioning plate facing the oxygen delivery mask, and the oxygen slow-flow box is connected to the valve control mechanism. The oxygen slow-flow box includes a slow-flow box body and a slow-flow box cover. The slow-flow box cover has multiple oxygen delivery slow-flow holes spaced around its circumference, penetrating its thickness direction and communicating with the inner cavity of the slow-flow box body.

[0004] The aforementioned patent has the following shortcomings: 1. The mounting sleeve in the aforementioned patent is a slip-on structure, which has problems such as unreliable fixation and easy detachment or loss during use. When the mounting sleeve is not tightened, its air valve control mechanism cannot function, resulting in situations such as the oxygen user not receiving oxygen in time; 2. The air valve control mechanism in the aforementioned patent uses a foot rod as a base point. The oxygen slow-flow box is pressed down by the action of the pressing rod to open and close the air valve of the oxygen tank. This method utilizes the elasticity of the foot rod itself, which may break after long-term use, causing the air valve control mechanism to fail and become unusable; 3. The air valve control mechanism and the mask body in the aforementioned patent are an integrated structure that cannot be separated. When a component is damaged, the entire unit needs to be replaced, resulting in high usage costs. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the above-mentioned technology and provide an oxygen tank breathing mask that works with a portable oxygen tank. The connection method is simple and the connection is firm. At the same time, it has a long service life and is easy to disassemble and replace parts.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] An oxygen tank breathing mask, characterized in that it includes a mask body and an air valve control mechanism disposed within the mask body. The mask body, from top to bottom, includes an oxygen delivery mask that fits against the mouth and nose of the user, a dividing plate, and a mounting sleeve that can be installed on the top of the oxygen tank. The inner wall of the mounting sleeve is provided with several claws that engage with the edge of the top of the oxygen tank for snap-fit ​​assembly. The air valve control mechanism includes a pressure plate and pressing rods and connecting rods disposed on both sides of the pressure plate. The pressure plate is disposed above the dividing plate, and a valve for supplying air is disposed at the center of its bottom surface. The connecting sleeve is inserted into the oxygen cylinder valve port. The pressure plate has an air outlet hole in the center that communicates with the inner cavity of the connecting sleeve. The dividing plate has a clearance hole in the center for the connecting sleeve to pass through. One end of the connecting rod is connected to the pressure plate, and the other end is provided with a cylindrical clamp. The cover is provided with a fastener that cooperates with the clamp to achieve a snap-fit ​​assembly. The clamp and the fastener are rotatably connected, so that the valve control mechanism can rotate up and down with the clamp as the base point. One end of the pressing rod is connected to the pressure plate, and the other end is a free end that extends out of the outside of the cover.

[0008] A further improvement of this utility model is that the fastener includes a lower fastener claw disposed on the side wall of the mounting sleeve and an upper fastener claw disposed on the side wall of the oxygen supply hood. A snap-fit ​​relief groove for inserting the end of the connecting rod is provided on the dividing plate between the upper and lower fastener claws. The upper and lower fastener claws are arranged in parallel, and a pair of lower fastener claws are provided on both sides of the lower fastener claw. When the snap-fit ​​is inserted into the fastener, the lower fastener claws play the role of supporting the snap-fit, and the upper fastener claws play the role of limiting the two ends of the snap-fit, so that the cylindrical snap-fit ​​can rotate between the upper and lower fastener claws without affecting the movement of the connecting rod.

[0009] A further improvement of this utility model is that a pressing relief groove is provided on the side wall of the oxygen supply hood, and the free end of the pressing rod extends out of the outside of the hood through the pressing relief groove.

[0010] A further improvement of this utility model is that the connecting rod and the pressure plate are vertically connected, and when the clip at the end of the connecting rod is embedded in the fastener, the pressure plate and the dividing plate are in a close fit.

[0011] A further improvement of this utility model is that the cover and the air valve control mechanism are both integrally injection molded structures.

[0012] A further improvement of this utility model is that the pressure plate is circular, and the pressure plate is provided with several vent holes that are directly opposite the relief hole. When the oxygen output speed of the oxygen tank is greater than the output speed of the vent hole, the excess oxygen is discharged through the bottom of the connecting sleeve and then through the relief hole and discharged through the vent hole.

[0013] A further improvement of this utility model is that a reinforcing ring is provided along the edge on the top surface of the pressure plate to strengthen the overall air valve control mechanism and prevent it from breaking under pressure.

[0014] A further improvement of this invention is that the free end of the pressing rod has an arc-shaped structure, which facilitates pressing with the fingers.

[0015] A further improvement of this utility model is that four vent holes are provided and are evenly distributed around the outer periphery of the connecting sleeve.

[0016] A further improvement of this utility model is that the claws are provided in three places and are evenly distributed along the circumferential direction of the inner wall of the mounting sleeve.

[0017] The beneficial effects of this utility model are as follows:

[0018] The mounting sleeve in this utility model adopts a snap-on structure. The clips can be firmly snapped and fastened to the edge of the oxygen cylinder mouth to prevent it from falling off and being lost due to unreliable fixation, as well as to prevent oxygen from being dispensed in a timely manner due to insufficient pressure.

[0019] The air valve control mechanism of this utility model has a snap-fit ​​rotating connection structure for its connecting rod, which allows the air valve control mechanism to rotate up and down around the snap-fit ​​point, resulting in better performance, longer service life, and less risk of breakage.

[0020] The air valve control mechanism and the cover in this utility model are connected separately. When a certain part is damaged, it can be easily replaced without replacing the whole thing, thus saving on usage costs.

[0021] This invention has a simple structure, and users do not need to exert much effort to open the oxygen tank to inhale oxygen. It is not only beneficial for users in emergency situations, but also applicable to a wider age range, and is more suitable for users with weaker physical strength or younger age.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0030] like Figure 1-6 As shown, an oxygen tank breathing mask includes a mask body 1 and an air valve control mechanism 2 disposed within the mask body 1. The mask body 1, from top to bottom, includes an oxygen delivery mask 3 that can be placed against the mouth and nose of the oxygen user, a dividing plate 4, and an installation sleeve 5 that can be installed on the top of the oxygen tank. The inner wall of the installation sleeve 5 is provided with several claws 6 that cooperate with the top edge of the oxygen tank to achieve a snap-fit ​​assembly. The air valve control mechanism 2 includes a pressure plate 7 and pressing rods 8 and connecting rods 9 disposed on both sides of the pressure plate 7. The pressure plate 7 is disposed above the dividing plate 4, and the bottom center of the pressure plate 7 is provided with a valve port for the oxygen tank to be inserted. The connecting sleeve 10 is inserted, and the pressure plate 7 has an air outlet 11 in the center that communicates with the inner cavity of the connecting sleeve 10. The dividing plate 4 has a clearance hole 12 in the center for the connecting sleeve 10 to pass through. One end of the connecting rod 9 is connected to the pressure plate 7, and the other end is provided with a cylindrical clip 13. The cover 1 is provided with a fastener 14 that cooperates with the clip 13 to achieve a snap-fit ​​assembly. The clip 13 and the fastener 14 are rotatably connected, so that the air valve control mechanism 2 can rotate up and down with the clip 13 as the base point. One end of the pressing rod 8 is connected to the pressure plate 7, and the other end is a free end that extends out of the outside of the cover 1.

[0031] In this embodiment, the fastener 14 includes a lower fastener 15 disposed on the side wall of the mounting sleeve 5 and an upper fastener 16 disposed on the side wall of the oxygen supply hood 3. A snap-fit ​​relief groove 17 for inserting the end of the connecting rod 9 is provided on the dividing plate 4 between the upper fastener 16 and the lower fastener 15. The upper fastener 16 and the lower fastener 15 are arranged in parallel, and a pair of lower fasteners 15 are provided on both sides of the lower fastener 15. When the clip 13 is inserted into the fastener 14, the lower fastener 15 plays the role of supporting the clip 13, and the upper fastener 16 plays the role of limiting the two ends of the clip 13, so that the cylindrical clip 13 can rotate between the upper fastener 16 and the lower fastener 15 without affecting the movement of the connecting rod 9.

[0032] In this embodiment, a pressing relief groove 18 is provided on the side wall of the oxygen supply hood 3, and the free end of the pressing rod 8 extends out of the outside of the hood 1 through the pressing relief groove 18.

[0033] In this embodiment, the connecting rod 9 is vertically connected to the pressure plate 7. When the clip 13 at the end of the connecting rod 9 is embedded in the fastener 14, the pressure plate 7 and the dividing plate 4 are in a close fit.

[0034] In this embodiment, both the cover 1 and the air valve control mechanism 2 are integral injection molded structures.

[0035] In this embodiment, the pressure plate 7 is circular, and the pressure plate 7 is provided with a number of vent holes 19 that are directly opposite the relief hole 12. When the oxygen output speed of the oxygen tank is greater than the output speed of the vent hole 11, the excess oxygen is discharged through the bottom of the connecting sleeve 10 and then through the relief hole 12 and discharged from the vent hole 19.

[0036] In this embodiment, a reinforcing ring 20 is provided along the edge on the top surface of the pressure plate 7 to reinforce the air valve control mechanism 2 as a whole and prevent it from breaking under pressure.

[0037] In this embodiment, the free end of the pressing rod 8 has an arc-shaped structure, which makes it easy for the fingers to press.

[0038] In this embodiment, there are four vent holes 19, which are evenly distributed around the outer periphery of the connecting sleeve 10.

[0039] In this embodiment, three claws 6 are provided and are evenly distributed along the circumferential direction of the inner wall of the mounting sleeve 5.

[0040] Working principle of this utility model:

[0041] When the user needs to inhale oxygen, the mounting sleeve 5 of the cover 1 is connected to the mouth of the oxygen cylinder, and the oxygen cylinder is fastened by the claw 6. At this time, the valve port of the oxygen cylinder is inserted into the connecting sleeve 10 of the pressure plate 7, and the pressure plate 7 is lifted up. In this state, the pressure rod 8 is raised, and the pressure plate 7 is tilted.

[0042] The user will fasten the oxygen mask 3 to the mouth and nose area of ​​the face. After the mask is fitted, press the lever 8 with your finger to press down the pressure plate 7 and the connecting sleeve 10, which in turn presses down the oxygen tank valve. At this time, the oxygen tank valve is opened, and oxygen is sprayed out from the oxygen tank and from the vent 11. When the lever 8 is pressed again, the amount of oxygen sprayed out will increase and spray out from the vent 19.

[0043] After oxygen administration is complete, release the pressing lever 8. The connecting sleeve 10 will separate from the oxygen tank valve port, and the oxygen tank valve port will reset and close automatically, thus preventing oxygen from leaking out.

[0044] When the cover 1 or the valve control mechanism 2 is damaged, simply replace the corresponding cover 1 or valve control mechanism 2, and separate the clip 13 on the valve control mechanism 2 from the fastener 14 on the cover 1 to complete the separation of the cover 1 and the valve control mechanism 2.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
