Specific embodiments

[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] See Figures 1 to 3 , the present utility model provides a trunk lid 1 with an underwater breathing device 3, including the trunk lid 1. The trunk lid 1 is provided with a circular hole 12, and the underwater breathing device 3 is arranged below the circular hole 12. The underwater breathing device 3 includes a placement box 31, a buoyancy ball 32, an air inlet pipe 33, a forward one-way valve 332, a water storage tank 34, an intermediate pipe 35, a breathing nozzle 36, an air outlet pipe 37, and a reverse one-way valve 371. The placement box 31 is fixed on the trunk lid 1. The circular hole 12 provided on the trunk lid 1 enables the internal space of the placement box 31 of the underwater breathing device 3 located below the circular hole 12 to communicate with the external space of the car, so that the air inlet pipe 33 and the buoyancy ball 32 placed in the placement box 31 are located outside the overall closed structure of the car. When the car falls into the water, the buoyancy ball 32 can smoothly drive the air inlet pipe 33 to float, so that the air inlet of the air inlet pipe 33 can reach above the water level 4, and an air passage is formed in the air inlet pipe 33 between the car at the bottom of the water.

[0023] See Figures 2 to 4, Further, a buoyancy ball 32 is provided at the top of the intake pipe 33. The buoyancy ball 32 is responsible for driving the intake pipe 33 to float, so that the air inlet of the intake pipe 33 is located above the horizontal plane 4. A forward one-way valve 332 is provided on the intake pipe 33. The forward one-way valve 332 is in an open state when a person inhales, allowing outside air to smoothly enter the intake pipe 33. When a person exhales, the forward one-way valve 332 is in a closed state. When the forward one-way valve 332 is in a closed state, there is originally air (with a certain pressure) in the internal space connected from the position of the forward one-way valve 332 of the intake pipe 33 to the breathing nozzle 36. Under the action of the pressure, the waste gas exhaled by a person needs to be discharged from the position of the outlet pipe 37. The existence of the forward one-way valve 332 can prevent the waste gas exhaled by a person from accumulating in the intake pipe 33.

[0024] See Figures 2 to 4 , Further, the bottom of the intake pipe 33 passes through the placement box 31 and then connects to the top of the water storage device 34. The top of the water storage device 34 is connected to the intermediate pipe 35. The water storage device 34 serves to store water. The water that enters the intake pipe 33 will first enter the water storage device 34. Therefore, the water will not enter the intermediate pipe 35 that is also connected to the top of the water storage device 34 immediately. Only when the inside of the water storage device 34 is completely filled with water will the water enter the intermediate pipe 35. The setting of the water storage device 34 can largely prevent water choking. The intermediate pipe 35 is connected to the breathing nozzle 36. The breathing nozzle 36 is connected to the outlet pipe 37. A reverse one-way valve 371 is provided on the outlet pipe 37. The breathing nozzle 36 is connected to the intermediate pipe 35 and the outlet pipe 37. When a person inhales, outside air enters the human body through the intermediate pipe 35 and then through the breathing nozzle 36. When a person exhales, the waste gas enters the breathing nozzle 36 and is then discharged outside the underwater breathing device 3 through the outlet pipe 37. The reverse one-way valve 371 is in an open state when a person exhales, allowing the waste gas exhaled by a person to be smoothly discharged outside the underwater breathing device 3. When a person inhales, the reverse one-way valve 371 is in a closed state, which can prevent water from entering the inside of the underwater breathing device 3.

[0025] See Figure 3 and Figure 4, Further, a water outlet pipe 341 is provided at the bottom of the water storage tank 34. Switch valves 38 are provided on the water outlet pipe 341, the intermediate pipe 35, and the air outlet pipe 37. A water outlet pipe 341 is provided at the bottom of the water storage tank 34. The setting of the water outlet pipe 341 enables the water in the water storage tank 34 to be discharged from the water storage tank 34. The setting of the switch valve 38 can control the opening and closing of the pipeline. The switch valve 38 on the water outlet pipe 341 is in a closed state when the water in the water storage tank 34 does not need to be discharged. In the closed state of the switch valve 38 on the water outlet pipe 341, it can prevent the outside water from entering the water storage tank 34. The switch valve 38 on the intermediate pipe 35 is in a closed state when a person does not need to breathe through the breathing nozzle 36, which can prevent water from entering the water storage tank 34 through the intermediate pipe 35. When a person needs to breathe through the breathing nozzle 36, it needs to be in an open state so that fresh air can pass through the switch valve 38 smoothly. The switch valve 38 on the water outlet pipe 341 can be in an open state for a long time. The air outlet pipe 37 is short, and whether water enters its interior does not affect the use of the underwater breathing device 3. When water enters the air outlet pipe 37, a person can exhale to discharge the water in the air outlet pipe 37 from the air outlet pipe 37. When the water in the water storage tank 34 is full, the switch valve 38 on the water outlet pipe 341 needs to be opened, the switch valve 38 on the intermediate pipe 35 needs to be opened, and the switch valve 38 on the air outlet pipe 37 needs to be closed. At this time, a person can blow air into the breathing nozzle 36, and the air enters the water storage tank 34 through the intermediate pipe 35, squeezing out the water in the water storage tank 34. When the water in the water storage tank 34 cannot be discharged at one time, only the switch valve 38 on the water outlet pipe 341 can be closed. At this time, a person inhales, and after inhaling, the switch valve 38 on the water outlet pipe 341 is opened again, and air is blown into the breathing nozzle 36 again. This process can be repeated multiple times until the water in the water storage tank 34 is completely discharged. After the water in the water storage tank 34 is discharged, (at this time, the switch valve 38 on the intermediate pipe 35 is in an open state) the switch valve 38 on the water outlet pipe 341 is closed, and the switch valve 38 on the air outlet pipe 37 is opened, and then smooth breathing can be carried out again. The water storage tank 34 is in a transparent state. The transparent water storage tank 34 is convenient for observing the water level inside the water storage tank 34, avoiding a person's inability to judge the water level in the water storage tank 34 and causing water choking due to the full water in the water storage tank 34.

[0026] See Figure 1 and Figure 2, Further, the upper part of the intake pipe 33 located above the placement box 31 is regularly stored in the placement box 31 in a disc shape. The buoyancy ball 32 is located above the intake pipe 33 regularly stored in a disc shape. Placing the buoyancy ball 32 above the intake pipe 33 is conducive to the buoyancy ball 32 floating upward immediately in water. When the buoyancy ball 32 floats upward, it drives the intake pipe 33 to float upward. When the buoyancy ball 32 drives the intake pipe 33 to float upward, the intake pipe 33 regularly placed in a disc shape can be unfolded more smoothly, avoiding the intake pipe 33 being knotted due to being randomly placed, which may cause the buoyancy ball 32 to not float smoothly on the water surface 4. The placement box 31 is in a conical shape with a thick top and a thin bottom. The thick top and thin bottom of the placement box 31 enable the intake pipe 33 to avoid friction with the inner wall of the placement box 31 as much as possible when floating upward, and can reduce the influence of the placement box 31 on the intake pipe 33 when floating upward. Since the placement box 31 is conical and the intake pipe 33 is also in a disc shape inside the placement box 31, the conical placement box 31 can prevent the distance between the outer circle of the disc-shaped intake pipe 33 and the side wall of the placement box 31 from being inconsistent, which may cause extrusion at the position where the distance between the two is relatively close.

[0027] See Figure 3 and Figure 4 , Further, the breathing nozzle 36 is provided with two nasal plugs 361, and the nasal plugs 361 are used to block the nostrils to prevent water from entering the nostrils. The buoyancy ball 32 is elliptical, and a counterweight 321 is provided at the bottom of the buoyancy ball 32. The buoyancy ball 32 with the counterweight 321 at the bottom is similar to a tumbler. The bottom of the buoyancy ball 32 with the counterweight 321 is always located below, and the top of the buoyancy ball 32 with the air inlet of the intake pipe 33 is always located above. When the counterweight 321 is not provided on the buoyancy ball 32, the intake pipe 33 connected to the bottom of the buoyancy ball 32 can also play a role similar to that of the counterweight 321, making the bottom of the buoyancy ball 32 always located below.

[0028] See Figure 3 and Figure 5, Further, a dust-proof seal cover 13 is provided at the circular hole 12 of the trunk lid 1. One end of the dust-proof seal cover 13 is hinged to the trunk lid 1 through a hinge 14, and an ejector 2 fixed to the trunk lid 1 is provided at the other end of the dust-proof seal cover 13. The dust-proof seal cover 13 is used for the normal sealing, dust-proof and waterproof of the vehicle. One end of the dust-proof seal cover 13 being hinged to the trunk lid 1 can prevent the loss of the seal cover and facilitate the opening of the dust-proof seal cover 13. An ejector 2 fixed to the trunk lid 1 is provided at the other end of the dust-proof seal cover 13. The ejector 2 and the placement box 31 are fixed to the trunk lid 1 through a fixing frame 11. The ejector 2 includes an ejector body 23, a sliding rod 22, a retaining piece 21, and a handle 24. The sliding rod 22 passes through the ejector body 23. A retaining piece 21 is provided at the top position of the sliding rod 22, and a handle 24 is provided at the bottom of the sliding rod 22. The retaining piece 21 prevents the sliding rod 22 from detaching from the ejector body 23, and the handle 24 is convenient for people to hold. When it is necessary to open the dust-proof seal cover 13, a person holds the handle 24 and pushes it upwards with force to open the dust-proof seal cover 13. When the dust-proof seal cover 13 is opened, water enters the placement box 31, and the buoyancy ball 32 starts to float under the buoyancy of the water.

[0029] In summary, the present utility model provides a vehicle anti-drowning breathing device, including a trunk lid. The trunk lid is provided with a circular hole, and an underwater breathing device is arranged below the circular hole. The circular hole provided in the trunk lid enables the underwater breathing device below the circular hole to communicate with the outside of the vehicle, facilitating the buoyancy ball to drive the air inlet pipe to float upward in the water. The underwater breathing device includes a placement box, a buoyancy ball, an air inlet pipe, a forward one-way valve, a water storage device, an intermediate pipe, a breathing mouthpiece, an air outlet pipe, and a reverse one-way valve. The underwater breathing device can rely on the buoyancy of the buoyancy ball to drive the pipe orifice of the air inlet pipe to emerge from the water surface, forming a passage connecting the underwater space inside the vehicle and the outside air. The placement box is used to store the buoyancy ball and the air inlet pipe. The air inlet pipe can be regularly placed in the placement box, is not easily touched, and can avoid knotting, resulting in the air inlet pipe not being able to emerge from the water surface smoothly. A buoyancy ball is arranged at the top of the air inlet pipe, and the buoyancy ball can drive the top of the air inlet pipe to emerge from the water surface. A forward one-way valve is arranged on the air inlet pipe. The setting of the forward one-way valve enables the forward one-way valve to be in an open state when a person inhales, and can smoothly inhale the outside air into the body. When a person exhales, the forward one-way valve closes, which can prevent the waste gas exhaled by the person from being discharged into the air inlet pipe, and can avoid the situation where a person repeatedly inhales waste gas due to a too long pipeline and cannot inhale fresh air. The bottom of the air inlet pipe passes through the placement box and is connected to the top of the water storage device, and the top of the water storage device is connected to the intermediate pipe. The bottom of the air inlet pipe passes through the placement box and enters the interior of the vehicle. The water storage device can store the water entering from the air inlet pipe. The top of the water storage device is respectively connected to the air inlet pipe and the intermediate pipe, so that the water entering from the air inlet pipe immediately falls to the bottom of the water storage device. The intermediate pipe will only enter air before the water in the water storage device is full, which can prevent the person from choking due to the sudden water inlet of the air inlet pipe. The intermediate pipe is connected to the breathing mouthpiece. A person bites the breathing mouthpiece, and the breathing mouthpiece is a bridge for the person to exchange gases with the underwater breathing device. The breathing mouthpiece is connected to the air outlet pipe, and a reverse one-way valve is arranged on the air outlet pipe. The air outlet pipe is responsible for discharging the waste gas exhaled by the person from the underwater breathing device. The setting of the reverse one-way valve can prevent water from entering the interior of the air outlet pipe when a person inhales.
