Description

Technical Field

[0001] The utility model relates to the technical field of rubber boat inflation, in particular to an electric automatic inflation device for falling into water and a rubber boat. Background Art

[0002] Inflatable boats are lightweight, foldable, easy-to-carry and transport small watercraft, typically made of high-strength, wear-resistant synthetic rubber. Due to their versatility and flexibility, they are widely used in various water activities, including but not limited to river rafting, lake fishing, offshore exploration, rescue operations, and water sports.

[0003] Before using a rubber boat, it needs to be inflated. Currently, the known automatic inflation mechanism of inflatable products is composed of a disposable water-sensitive element, a disposable gas cylinder membrane, a high-pressure gas cylinder, a carbon dioxide mixture, a trigger mechanism and an inflation pipeline. After the inflatable product falls into the water, the disposable water-sensitive element melts when it encounters water, and the trigger mechanism punctures the membrane on the high-pressure gas cylinder. The carbon dioxide mixture directly enters the airbag of the inflatable product through the inflation pipeline to realize the automatic inflation of the inflatable product when it falls into the water. The inflation structure needs to strictly calculate the gas volume of the gas cylinder and consider the effect of temperature on the air pressure. Otherwise, it is easy to cause the airbag to be not fully inflated or the airbag to be inflated too much and the pressure is too high to explode. Among them, high-pressure gas cylinders are dangerous goods. They need to be stored, inflated and transported by dedicated personnel. The risk factor is relatively high. In addition, the water-sensitive element and the diaphragm are disposable products with high cost of use. Moreover, if the inflatable product leaks during use, it cannot be refilled.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Example 1

[0028] Reference Figures 1-4 As shown, the utility model discloses an electric automatic inflatable device for falling into water, comprising:

[0029] The support portion 1 includes a housing 11 and a pressure cover 12. The pressure cover 12 is buckled on one end of the housing 11. The other end of the housing 11 is provided with an air outlet 111.

[0030] The inflation part 2 is arranged inside the shell 11, and the inflation part 2 includes a one-way valve 22 and a suction fan 21. The outlet end of the one-way valve 22 is connected to the air outlet 111, the inlet end of the one-way valve 22 is connected to the outlet end of the suction fan 21, and the air inlet end of the suction fan 21 is in contact with the pressure cover 12; a control panel is provided inside the suction fan 21;

[0031] The detection unit 3 includes a water contact sensor 31 and a pressure sensor 32 . The water contact sensor 31 and the pressure sensor 32 are electrically connected to the control board.

[0032] As can be seen, the automatic inflation device of the present invention uses a water contact sensor 31 to detect water contact signals and determine whether the inflatable boat has been launched. Specifically, during actual installation, the water contact sensor 31 is installed at the bottom of the inflatable boat and is electrically connected to the suction fan 21. The suction fan 21 draws air from the outside into the inflatable boat to inflate the inflatable boat. To prevent the air injected into the inflatable boat from escaping, a one-way valve 22 is installed at the air outlet 111 of the suction fan 21, creating a one-way air path that prevents the air sucked into the inflatable boat from escaping. In the present invention, the housing 11 and the gland 12 serve as the support for the entire structure. The one-way valve 22 and the suction fan 21 are installed within the housing 11 and secured by the gland 12. During actual installation, the housing 11 is mounted on the top of the inflatable boat, with the air outlet 111 end of the housing 11 connected to the inflatable boat. The suction fan 21 draws air from the outside, which then passes through the one-way valve 22 and enters the inflatable boat from the air outlet 111, completing the inflation process. As a preferred solution of the present invention, the detection component also includes a pressure sensor 32. During the actual installation process, the pressure sensor 32 is installed inside the rubber boat. The specific location is selected on the air intake pipe of the rubber boat. It can be selected to be connected in series with the air intake pipe of the rubber boat to detect the pressure inside the rubber boat. When the air pressure inside the rubber boat reaches the set value, the suction fan 21 stops working. Similarly, when the air pressure inside the rubber boat is lower than the set value, the suction fan 21 is turned on again to inhale air. Preferably, a control board (PCB circuit board) is installed in the above-mentioned suction fan 21, which has a built-in control system, which can not only exchange signals but also realize remote control of the suction fan 21.

[0033] The present invention uses a water contact sensor 31 to feed back a water contact signal to the suction blower 21, enabling automatic inflation of the inflatable boat when it lands in the water. The entire structure eliminates the need to calculate the air volume, making it reusable and cost-effective, and unaffected by air pressure. Furthermore, through detection by the pressure sensor 32, the suction blower 21 can be remotely controlled to automatically refill air during use, ensuring the boat's normal operation.

[0034] Furthermore, the one-way valve 22 includes a first valve body 221, a second valve body 222 and a valve core 223, the valve core 223 is arranged between the first valve body 221 and the second valve body 222, the first valve body 221 is connected to the air outlet end of the suction fan 21, and the second valve body 222 is connected to the air outlet 111.

[0035] Specifically, the suction fan 21 sucks in the one-way valve 22, and the valve core 223 of the one-way valve 22 opens, and the gas enters from one side of the first valve body 221 and is output from one side of the second valve body 222. In the present invention, a guide rod 224 is provided at one end of the valve core 223 close to the second valve body 222. The guide rod 224 passes through the second valve body 222. An elastic element 225 is sleeved on the outer side of the guide rod 224, and the two ends of the elastic element 225 are respectively in contact with the valve core 223 and the second valve body 222. When the suction fan 21 is not working, the tension of the elastic element 225 itself presses the valve core 223 against the first valve body 221, and the two sides are not connected. When the suction fan 21 is working, the air pressure presses the valve core 223, the elastic element 225 is compressed, and the valve core 223 leaves the first valve body 221, completing the unidirectional delivery of gas.

[0036] Furthermore, as a preferred solution of the present invention, the side of the valve core 223 away from the guide rod 224 is a spherical surface, and one side of the spherical surface of the valve core 223 abuts against the first valve body 221. The spherical sealing improves the sealing effect of the one-way valve.

[0037] Furthermore, a sealing ring 226 is provided at one end of the first valve body 221 that is in contact with the suction fan 21 , and the sealing ring 226 is provided between the housing 11 and the first valve body 221 .

[0038] Specifically, the sealing ring 226 is sleeved on the outside of one end of the first valve body 221 and is pressed tightly between the housing 11 and the first valve body 221 during the assembly process, thereby improving the sealing performance of the entire one-way valve 22 after assembly.

[0039] Furthermore, the inflatable portion 2 further includes at least two inflatable hoses 15, which are in communication with the air outlet 111 of the housing 11. The air outlet 111 is provided with a multi-way connection valve 14, and the inflatable hoses 15 are connected to the multi-way connection valve 14 via a clamp 16.

[0040] Furthermore, the present invention adopts a multi-way connecting valve 14 disposed at the air outlet 111 of the housing 11, connecting multiple inflation hoses 15, thereby achieving simultaneous inflation from multiple air holes and improving inflation efficiency. As a preferred embodiment of the present invention, a clamp 16 is used to detachably connect the air pipe to the multi-way connecting valve 14.

[0041] Furthermore, the detection unit 3 further includes a battery 33 , and the battery 33 is electrically connected to the suction fan 21 .

[0042] Specifically, the battery 33 provides power to the suction fan 21 to meet the normal use of the suction fan 21, and the battery 33 can also provide power to the pressure sensor 32 and the water contact sensor 31 to ensure the normal use of the pressure sensor 32 and the water contact sensor 31.

[0043] Furthermore, a first mounting slot 112 and a second mounting slot 113 are provided inside the housing 11 , the one-way valve 22 cooperates with the first mounting slot 112 , and the suction fan 21 cooperates with the second mounting slot 113 .

[0044] Furthermore, an air filter 13 is provided at the air inlet end of the suction fan 21 , and the air filter 13 is inserted into the pressure cover 12 .

[0045] Specifically, an air filter 13 is provided at the air inlet end of the suction fan 21, which can effectively filter out impurities in the air. On the one hand, it can prevent impurities from being sucked into the rubber boat, and on the other hand, it can prevent impurities from blocking the internal suction fan 21 and the one-way valve 22.

This device utilizes a water contact sensor 31 to feed back a water contact signal to a suction blower 21, achieving automatic inflation of the inflatable boat. The entire structure eliminates the need to calculate air volume, enabling repeated use at low cost and unaffected by air pressure. Furthermore, through pressure sensor 32 detection, the suction blower 21 can be remotely controlled to automatically inflate the inflatable boat during use, ensuring normal operation.
