Description

Technical Field

[0001] This utility model belongs to the field of rescue equipment technology, specifically an underwater rescue mask. Background Technology

[0002] Currently, rescue equipment, as a crucial specialized tool, is widely used in fields such as deep-sea diving, emergency rescue, maritime rescue, and healthcare. Among these, water rescue equipment is typically used in flood relief and disaster response operations to promptly rescue individuals who have fallen into the water. Common examples include lifeboats, life jackets, and life rings, which are widely used in shipping, fishing, water and dock operations, and water sports. This equipment generally ensures that a person who has fallen into the water floats safely on the surface, thus preventing drowning.

[0003] However, for some emergencies, such as when someone is drowning and unable to breathe, how to provide timely underwater rescue becomes a crucial issue. Therefore, the existing technical solutions mentioned above have the following shortcomings: Currently, in the field of rescue equipment technology, most common rescue equipment is water rescue equipment such as life jackets. When someone is drowning and unable to breathe, rescuers usually cannot perform inflatable resuscitation in the water. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an underwater rescue mask to solve the problem mentioned in the background art that most existing water rescue equipment cannot be used by rescuers to blow air into the water.

[0005] This utility model embodiment is implemented as follows: an underwater rescue mask, including an airbag, and further comprising:

[0006] An air intake pipe is provided on the airbag and is used to communicate with the airbag;

[0007] An inflation port, fitted onto the air inlet pipe, is used for inflation to allow gas to enter the airbag through the air inlet pipe; and an inflation valve structure, disposed between the airbag and the air inlet pipe, is used to create a certain gap inside the inflation valve structure under gas compression when the inflation port is inflated, thereby allowing gas to enter the airbag.

[0008] Preferably, the inflation valve structure includes a sealing ring, a soft rubber plug, and a soft rubber outer tube, wherein the lower end of the soft rubber outer tube is connected to the airbag, the lower end of the air inlet pipe is attached to the inner wall of the soft rubber outer tube, and the lower half of the sealing ring and the soft rubber plug are fitted onto the inner wall of the soft rubber outer tube.

[0009] The beneficial effects of this utility model are:

[0010] Compared with the prior art, the underwater rescue mask provided by this utility model includes an airbag, an air inlet pipe, an inflation port, and an inflation valve structure. The device forms a seal between the air inlet pipe and the airbag through the setting of the inflation valve structure. When the inflation port is inflated, a certain gap can be formed inside the inflation valve structure under gas compression or manual compression, which cannot form a seal, and gas enters the airbag to complete the inflation. When someone is drowning and cannot exhale, the rescuer can cover the person's mouth and nose with the underwater rescue mask, and the edge of the airbag will block the nose. The rescuer can then perform inhalation resuscitation in the water, which solves the problem that most existing water rescue equipment cannot allow the rescuer to perform inhalation resuscitation in the water.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

In addition, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figure 1-5 The diagram shown is a structural diagram of an underwater rescue mask according to an embodiment of the present invention. The underwater rescue mask includes an airbag 1 and further includes:

[0026] An air intake pipe 2 is disposed on the airbag 1 and is used to communicate with the airbag 1;

[0027] Inflation port 3, sleeved on the air inlet pipe 2, is used for inflation to allow gas to enter the airbag 1 through the air inlet pipe 2; and

[0028] An inflation valve structure is located between the airbag 1 and the air inlet pipe 2. When the inflation port 3 is inflated, the inflation valve structure can form a certain gap under the pressure of gas, so that gas can enter the airbag 1 and complete the inflation of the airbag 1.

[0029] In this embodiment of the invention, specifically, under normal conditions, due to the setting of the inflation valve structure, a seal is formed between the air inlet pipe 2 and the airbag 1. When the inflation port 3 is inflated, gas enters the air inlet pipe 2. The internal structure of the inflation valve can form a certain gap under gas compression or manual compression, and cannot form a seal. The gas then enters the airbag 1, completing the inflation of the airbag 1. When someone is drowning and unable to exhale, the rescuer can cover the person's mouth and nose with the underwater rescue mask, and the edge of the airbag 1 will block the nose. The rescuer can then perform inflatable rescue in the water, solving the problem that most existing water rescue equipment cannot perform inflatable rescue in the water.

[0030] Furthermore, in a preferred embodiment of this utility model, an air inlet 4 is also provided at the axis of the airbag 1, and the use of the air inlet 4 can be selected as needed. In practical applications, the upper end of the air inlet 4 passes through the airbag 1 and is detachably equipped with a sealing cover. The lower air inlet of the air inlet 4 is used to aim at the mouth of the drowning person. The sealing cover can be implemented using existing technologies such as threaded caps. When the air inlet 4 needs to be used, the sealing cover can be opened to blow air; when the air inlet 4 does not need to be used, the sealing cover can be closed to seal the upper opening of the air inlet 4. When someone is drowning and unable to exhale, the rescuer can cover the person's mouth and nose with a mask, aim the lower air inlet of the air inlet 4 at the mouth of the drowning person, and block the nose with the edge of the airbag 1, allowing the rescuer to perform air resuscitation in the water.

[0031] Furthermore, in a preferred embodiment of this utility model, the inflation valve structure includes a sealing ring 5, a soft rubber plug 6, and a soft rubber outer tube 7, wherein the lower end of the soft rubber outer tube 7 is connected to the airbag 1, the lower end of the air inlet pipe 2 is attached to the inner wall of the soft rubber outer tube 7, the lower half of the sealing ring 5 and the soft rubber plug 6 are fitted onto the inner wall of the soft rubber outer tube 7, the inner wall of the air inlet pipe 2 is provided with multiple air guiding grooves 8, and the outer side wall of the soft rubber plug 6 is provided with a ventilation groove 10.

[0032] In one embodiment of this utility model, specifically, under normal conditions, since the inner side of the sealing ring 5 is fitted on the upper part of the soft rubber plug 6, and the outer side of the sealing ring 5 is fitted on the inner wall of the soft rubber outer tube 7, the contact point between the sealing ring 5 and the inner cavity of the soft rubber outer tube 7 forms a seal. Combined with the function of the upper part of the soft rubber plug 6, water can be prevented from entering the airbag 1. When the inflation port 3 is inflated, gas enters the inner cavity of the soft rubber outer tube 7 from the air guide groove 8 on the inner wall of the air inlet pipe 2. As the gas is compressed, the contact point between the sealing ring 5 and the inner cavity of the soft rubber outer tube 7 can no longer form a seal, forming a certain gap. The gas then enters the airbag 1 through the ventilation groove 10 of the soft rubber plug 6, completing the inflation of the airbag 1.

[0033] Furthermore, in a preferred embodiment of this utility model, an oxygen-enhancing port 9 is also provided on the upper side of the air blowing port 4, and a sealing element 11 is installed on the oxygen-enhancing port 9.

[0034] In this embodiment of the invention, specifically, during underwater emergency rescue in shallow water, when someone is drowning and unable to breathe, the rescuer can cover the victim's mouth and nose with the underwater rescue mask. That is, the side of the airbag 1 furthest from the air inlet 4 is placed against the drowning victim's mouth and nose. At this time, the lower air inlet of the air inlet 4 is aligned with the drowning victim's mouth, and the edge of the airbag 1 blocks the nose. The rescuer can then perform inhalation resuscitation underwater. If high oxygen is needed, oxygen can be injected through the high oxygen inlet 9, and combined with the rescuer's inhalation, the oxygen will be delivered into the drowning victim's mouth and lungs. Furthermore, the high oxygen inlet 9 can be sealed with a sealing element 11. The sealing element 11 can be a sealing plug, a cap, or other sealing structure, selected according to need; no limitation is made here. When it is necessary to inject oxygen through the high oxygen inlet 9, the sealing element 11 can be opened for use.

[0035] Furthermore, in a preferred embodiment of this utility model, the oxygen-enhancing port 9 is connected to the air-blowing port 4 via a connector 12. Specifically, the lower end of the oxygen-enhancing port 9 is connected to the connector 12, and the connector 12 is connected to the air-blowing port 4, thereby enabling oxygen injection through the oxygen-enhancing port 9. Additionally, the connector 12 can be a detachable pipe structure or a sealed pipe installed by welding, bonding, or other methods; the choice is based on specific needs and is not limited here.

[0036] It should be noted that, in the structure of the underwater rescue mask, the inflation valve structure of the airbag 1 is particularly important to protect. Broadly speaking, this includes the inflation port 3, which is fitted onto the air inlet pipe 2. The lower half of the air inlet pipe 2, the sealing ring 5, and the soft rubber plug 6 are fitted onto the inner wall of the soft rubber outer tube 7. The inner wall of the air inlet pipe 2 has multiple air guiding grooves 8. In practical applications, air can be blown into the inflation port 3 manually, or an external inflation device can be used to inflate the inflation port 3. This allows gas to enter the inner cavity of the soft rubber outer tube 7 from the air guiding grooves 8. As the gas is compressed, the contact point between the sealing ring 5 and the inner cavity of the soft rubber outer tube 7 cannot form a seal, creating a certain gap. The gas then enters the airbag 1 through the venting groove 10 of the soft rubber plug 6, completing the inflation of the airbag 1.

[0037] Additionally, when someone is drowning and unable to breathe, the rescuer can cover the person's mouth and nose with the underwater rescue mask, and block the nose with the edge of the airbag 1. The rescuer can then perform inflatable resuscitation underwater. By blowing air into the airbag, the rescuer uses their fingers to pinch the sealing ring 5 through the soft rubber outer tube 7, deforming it into an oval shape. This prevents a seal, allowing air to enter the airbag 1 through the gaps and inflate it. To deflate the airbag, the rescuer uses their fingers to pinch the sealing ring 5 through the soft rubber outer tube 7, deforming it into an oval shape, and squeezes the airbag 1 with their other hand to expel the air.

[0038] Furthermore, as a preferred embodiment of this utility model, the air intake direction of the underwater rescue mask during inflating and the exhaust flow direction during deflating are as follows: Figure 6-9 As shown. Specifically, Figure 6 and Figure 8 These are schematic diagrams illustrating the air intake direction during inflating and the exhaust flow direction during deflating, respectively, of an underwater rescue mask according to one embodiment of this utility model. Figure 7 for Figure 6 A partial schematic diagram. Figure 9 for Figure 8 A partial schematic diagram is shown. During air intake, an external inflation device is used to inflate the air inlet 3, allowing gas to enter the inner cavity of the soft rubber outer tube 7 through the air guide groove 8. As the gas is compressed, the contact point between the sealing ring 5 and the inner cavity of the soft rubber outer tube 7 cannot form a seal, creating a gap. The gas then enters the airbag 1 through the vent groove 10 of the soft rubber plug 6, completing the inflation of the airbag 1. Alternatively, air can be blown in with the mouth, and the fingers can be used to pinch the sealing ring 5 through the soft rubber outer tube 7, deforming it into an oval shape. This prevents a seal, allowing gas to enter the airbag 1 through the gap for inflation. During deflation, the fingers can be used to pinch the sealing ring 5 through the soft rubber outer tube 7, deforming it into an oval shape, while the other hand squeezes the airbag 1 to expel the gas, facilitating storage.

[0039] The implementation principle of this embodiment is as follows: When someone is drowning and unable to exhale, the rescuer can cover the person's mouth and nose with an underwater rescue mask, with the air inlet at the bottom of the inflator 4 aligned with the drowning person's mouth, and the edge of the airbag 1 blocking the nose. The rescuer can then perform inflator resuscitation in the water. If high oxygen is required, oxygen can be injected through the high oxygen inlet 9, and the rescuer can work together to deliver the oxygen into the drowning person's mouth and lungs.
