Description

Technical Field

[0001] The utility model relates to the field of inflation equipment, in particular to an integrated high-pressure inflation device. Background Art

[0002] Inflatable boats are a very common type of boat, which are used in rescue, entertainment, sports and other fields. Inflatable boats are equipped with corresponding inflation equipment. Existing inflation structures often only have the function of connecting to the inflation valve, and cannot detect and control the air pressure inside the airbag. When the inflation pressure is very high and the pressure inside the airbag cannot be detected, there will be a risk of bursting after exceeding the rated pressure, resulting in damage to the airbag. In severe cases, it may even cause injury to the operator, posing a serious hazard.

[0003] Taking the common inflation handle as an example, when inflating with high-pressure gas, the operator needs to use experience to test the airbag pressure by hand and manually close the inflation device. Due to the excessive gas pressure, the gas flow into the airbag is very large, and the airbag pressure cannot be well controlled. It is often not closed in time, causing the airbag to be over-pressurized. In severe cases, it may even exceed the airbag's tolerance and explode, threatening the operator's personal safety.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See also Figure 1-Figure 3 , this application provides the following technical solutions:

[0041] An integrated high-pressure inflatable device includes a main body 1 with a cavity formed therein, and an air inlet, an air outlet, a pressure relief port and a detection port are provided on the main body 1; the air inlet, the air outlet, the pressure relief port and the detection port are all connected to the interior of the cavity. The air inlet is used to connect to an external inflatable device, and the air outlet is used to connect to a device to be inflated; the external inflatable device here is generally a high-pressure inflatable tank, and the device to be inflated is based on the specific conditions of use, such as an inflatable boat, an inflatable surfboard, etc. A detection member 2 is provided at the detection port, and the air pressure in the cavity is obtained through feedback from the detection member 2. Because the cavity is connected to the interior of the device to be inflated during inflation, the air pressure inside the device airbag can be obtained based on the air pressure in the cavity. A pressure relief member is provided at the pressure relief port, and the pressure inside the cavity is relieved through the pressure relief member, thereby ensuring the safety of the airbag inside the inflatable device and avoiding overinflation.

[0042] On the basis of the above implementation scheme, the main body 1 includes a cylinder 11 with a straight cylindrical structure, and a cavity is provided inside the cylinder 11. The cavity is provided coaxially with the cylinder 11, and the cavity runs through both ends of the length direction of the cylinder 11. One end of the cylinder 11 is an air inlet, and the other end is an air outlet. A gripping structure is provided on the outside of the cylinder 11, and the gripping structure is used to facilitate the user to grasp the main body 1. The gripping structure can adopt a variety of different settings including a handle, a gripping rod, etc. according to actual conditions. The gripping structure of this scheme is a plurality of annular grooves provided on the outer wall of the cylinder 11, and the groove bottom is provided with an arc surface, which is close to the finger-imitation structure of a human hand. The pressure relief port on the main body 1 is provided near one end of the air outlet, and the gripping structure is located between the pressure relief port and the air inlet. Because a pressure relief part needs to be provided at the pressure relief port, the pressure relief part will form an extended structure on the outside of the cylinder 11, and considering the user's comfort level of force application, it is also convenient to set the gripping structure between the pressure relief port and the air inlet. Figure 1The upper area of ​​the cylinder 11 is placed in the direction of use. When in use, the user can hold the cylinder 11 and use the lower edge of the palm to push the upper end surface of the pressure relief piece to push the device toward the inflation nozzle of the device to be inflated. This structure of the device is more convenient whether it is connecting the device or applying force to maintain the connection state.

[0043] On the basis of the above implementation scheme, the detection port is opened on the wall of the cylinder 11, the detection member 2 is a digital pressure sensor, and the sensing end of the detection member 2 is set at the detection port. In addition to the digital pressure sensor, the detection member 2 can also use other forms of pressure sensing devices, as long as it can normally feedback the pressure value. Because the digital pressure sensor technology is very mature, and the display results are intuitive and accurate, this solution uses a digital pressure sensor. When in use, you only need to press the detection switch on the sensor to read the pressure value through the display screen.

[0044] On the basis of the above implementation scheme, two pressure relief ports are provided, and the pressure relief parts corresponding to the two pressure relief ports are divided into high-pressure pressure relief parts 3 and low-pressure pressure relief parts 4, and the high-pressure pressure relief parts 3 and the low-pressure pressure relief parts 4 are respectively connected to one pressure relief port. The high-pressure pressure relief parts 3 and the low-pressure pressure relief parts 4 are both pressure relief valves; and the outer ends of the high-pressure pressure relief parts 3 and the low-pressure pressure relief parts 4 are respectively provided with covers.

[0045] The high-pressure relief member 3 and the low-pressure relief member 4 can be selected as pressure relief structures that can be automatically opened under the push of the internal gas pressure. The high-pressure relief member 3 and the low-pressure relief member 4 use springs with different elasticity. According to the actual inflatable equipment, if the air pressure requirement is low, only the cover of the low-pressure relief member 4 can be opened. In this state, whether the cover of the high-pressure relief member 3 is opened or closed, it does not affect the use. Different from this, if the air pressure requirement is high, the cover of the low-pressure relief member 4 needs to be closed to ensure that the position of the low-pressure relief member 4 will not leak. Only the high-pressure relief member 3 is used for work.

[0046] Based on the above implementation scheme, see Figure 4 and Figure 5 The air outlet of the main body 1 is threadedly connected to the inflatable member 5; the inflatable member 5 includes a first inflatable connection part, a second inflatable connection part and an inflatable grip part. The first inflatable connection part is used to connect with the inflatable port of the device to be inflated; the second inflatable connection part is used to connect with the air outlet of the main body 1; the inflatable grip part is arranged between the first inflatable connection part and the second inflatable connection part, and the inflatable grip part is provided with an anti-slip structure for increasing the friction force when twisting. In this solution, the inflatable grip part is annular as a whole, and groove structures are evenly arranged on its outer side.

[0047] The first inflatable connection part of the inflatable member 51 adopts a connection structure with an internal thread, and the air outlet of the cylinder 11 is correspondingly provided with an external thread. The first inflatable connection part is screwed on the outside of the air outlet of the cylinder 11, and a sealing ring is provided at the connection between the two to prevent air leakage. The inflatable member 51 can be provided with a variety of different structural forms so that it can be applied to different inflatable devices. Only one structure is given in the drawings of this scheme, but it is not limited to this one in actual production.

[0048] On the basis of the above implementation scheme, an inner core 7 is arranged in the cavity of the main body 1, and the inner core 7 is a straight tubular structure made of metal material; a clamping structure is arranged in the middle of the inner core 7, which can be clamped with the inside of the main body 1; one end of the inner core 7 extends to the air outlet of the main body 1, and the other end extends to the outside of the air inlet of the main body 1. In this solution, the clamping structure of the inner core 7 is an annular boss arranged on the outside of its tube body, and a clamping groove is arranged inside the cylinder 11 corresponding to the annular boss.

[0049] An air intake assembly 6 is provided at the air intake port of the main body 1, and the air intake assembly 6 includes an air intake connector 61 and an air intake pipeline 62. One end of the air intake connector 61 is detachably connected to the main body 1; the other end is connected to the air intake pipeline 62. An internal thread is provided at the air intake port of the main body 1, and an external thread is provided at one end of the inner core 7 close to the air intake port. The air intake connector 61 of the air intake assembly 6 is sleeved between the inner core 7 and the main body 1, and the inner side wall and the outer side wall of the air intake connector 61 are respectively provided with an internal thread and an external thread, which are threadedly connected to the main body 1 and the inner core 7. A sealing ring is provided at the connection between the air intake connector 61 and the cylinder 11. Through this structure, it can be ensured that the air intake connector 61 and the cylinder 11 are firmly connected.

[0050] The main body 1 has a first cavity and a second cavity. One end of the first cavity extends to the air inlet, and the inner diameter of the first cavity corresponds to the outer diameter of the inner core 7. The second cavity is connected to the first cavity and is arranged at the end of the first cavity facing the air outlet. The inner diameter of the second cavity is larger than the outer diameter of the inner core 7, and the detection port and the pressure relief port are both arranged on the wall of the second cavity. The aforementioned card slot is arranged in the first cavity. The second cavity of this scheme is Figure 5 In the lower cavity structure, the airflow in the airbag of the inflatable device can enter the interior of the device from the air inlet, that is, the lower port in the figure, and a part of the airflow contacts the detection member 2 and the two pressure relief members through the second cavity.

[0051] Through this structural form of the present solution, a metal inner core 7 is arranged inside the cylinder 11, which can well enhance the pressure bearing effect of the present device. The inner core 7 extends to the outside of the air inlet of the cylinder 11, and the airflow of the high-pressure gas tank directly enters the inner core 7 through the air inlet connector 61, thereby not causing impact force on the cylinder 11. The airflow fed back from the airbag of the self-contained inflatable device can be passed into the detection component 2 and the two pressure relief components at the second cavity.

[0052] On the basis of the above embodiment, a gas nozzle is provided at the end of the air inlet pipeline 62, one of which is connected to the air outlet of the high-pressure gas tank, and the other is connected to the air inlet connector 61. The gas nozzle of the air inlet pipeline 61 adopts a rugby-shaped structure, with a convex middle and narrowed ends. An airway is provided inside the gas nozzle, and the inner diameter of the airway is smaller than the inner diameter of the inner core 7, which is about one-third to one-quarter of the inner diameter of the inner core 7. In this way, while ensuring that the overall strength of the gas nozzle is sufficient, it has a greater output force during inflation, ensuring good inflation efficiency.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
