Description

Technical Field

[0001] The invention relates to the technical field of inflatable boats, in particular to a multi-air chamber communication device for inflatable boats. Background Art

[0002] An inflatable boat is an inflatable boat, mostly made of rubber, so it is also called a rubber boat. It can be compressed when not inflated. It is driven by a motor or manpower. In order to improve the safety of the inflatable boat's navigation, improve the reliability of the inflatable boat, and prevent the sudden damage of the air chamber and the leakage of all the gas, the air chamber is usually divided into several sealed compartments of similar volume by elastic partitions, each of which is equipped with an inflation device. In the existing multi-chamber inflatable boat, each air chamber is equipped with an air nozzle or inflation device, and the user needs to inflate and deflate multiple air chambers one by one, which is inconvenient to operate.

[0003] The Chinese patent utility model with the publication number of CN220884721U discloses a multi-chamber inflatable boat communication device, including a bottom plate, two push-type inflating nozzles are arranged on the bottom plate, and a push switch is arranged at the upper end of the push-type inflating nozzle, and the push switch is located at the top of the bottom plate. An elastic cover is arranged above the bottom plate, and the elastic cover is sealed and connected with the bottom plate, and a cavity channel is arranged between the elastic cover and the bottom plate. The utility model connects multiple air chambers, and arranges the cavity channel outside the air chamber. At the same time, a push-type inflating nozzle is used to replace the valve body located in the air chamber and the knob located outside the inflatable boat. However, after the device is installed on an inflatable boat with multiple air chambers, all the push switches need to be opened one by one to perform the inflation and deflation operation, which is complicated to operate, and the elastic cover is exposed to the outside of the inflatable boat and is easily damaged. Frequent opening and closing of the elastic cover also causes the elastic cover to have poor sealing with the bottom plate, which is easy to leak, affecting the inflation and deflation effect. Summary of the invention

[0004] The object of the present invention is to provide a multi-air chamber communication device for an inflatable boat.

[0005] A multi-chamber communication device for an inflatable boat comprises a shell, wherein an air charging and discharging passage is arranged inside the shell, a one-way valve device is arranged on one side of the shell, and a driving device for controlling the movement of the one-way valve device is arranged inside the shell.

[0006] Furthermore, the one-way valve device includes a bracket seat fixed on one side of the shell, a sliding hole is opened in the middle of the bracket, a sliding rod is slidably arranged in the sliding hole, a plurality of charging and discharging holes are opened on the bracket outside the sliding hole, a card slot is opened on the side of the bracket seat away from the shell, a silicone umbrella valve is arranged in the card slot, one end of the sliding rod is fixedly connected to the silicone umbrella valve, and the other end of the sliding rod cooperates with the driving device.

[0007] Furthermore, the driving device includes a driving motor, which is fixedly arranged inside the shell, and a connecting rod is fixedly arranged at the output end of the driving motor. A toggle rod is arranged on the connecting rod, and a toggle groove is opened at one end of the sliding rod away from the silicone umbrella valve. The toggle rod is movably arranged in the toggle groove and contacts and cooperates with both ends thereof.

[0008] Furthermore, the driving device also includes a control switch, and the control switch is electrically connected to the driving motor.

[0009] In summary, the beneficial effects of the present invention are as follows: the present invention is arranged on the partition inside the inflatable hull, is not easy to be damaged, has a long service life, has good sealing performance, is operated with one button, and is easy to use. The present invention connects multiple air chambers to inflate and deflate the inflatable hull with multiple air chambers. When the pumping and inflating device inflates the multiple air chambers, the one-way valve device automatically opens under the action of the airflow, and the pumping and inflating device controls the airflow from the air chamber relatively close to the pumping and inflating device through the one-way valve device to enter the air chamber relatively far away from the pumping and inflating device, thereby completing the inflation of the inflatable hull. After the inflation is completed, the one-way valve device is automatically closed by the air pressure in the air chamber relatively far away from the pumping and inflating device, and the air in the two adjacent air chambers cannot circulate through the one-way valve device. When the pumping and inflating device deflates the multiple air chambers, the driving device controls the one-way valve device to move and open the one-way valve device, and the pumping and inflating device controls the airflow from the air chamber relatively far away from the pumping and inflating device through the one-way valve device to enter the air chamber relatively close to the pumping and inflating device, and then discharges from the pumping and inflating device, thereby completing the deflation of the inflatable hull.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The following is combined with Figure 1-4 The present invention is further described as follows: a multi-chamber communication device for an inflatable boat comprises a shell 1, an interior of the shell 1 is provided with an air charging and discharging passage 2, a one-way valve device is provided on one side of the shell 1, and a driving device for controlling the movement of the one-way valve device is provided inside the shell 1.

[0017] In this embodiment, the overall structure of the inflatable hull 14 and the pumping and inflating device 17 are derived from the Chinese invention patent "A multi-chamber inflatable boat and its inflation and deflation method" with publication number CN115675730A, and the specific structure is not repeated. The outer wall of the shell 1 is sealed and connected to the partition 15 of the two adjacent air chambers 16 inside the inflatable hull 14. The two ends of the shell 1 are respectively arranged in the two air chambers 16 on both sides of the partition 15, and the inflation and deflation channel 2 connects the two air chambers 16. The one-way valve device is arranged in the air chamber 16 relatively far away from the pumping and inflating device 17.

[0018] like Figure 3 As shown, when the pumping and inflation device 17 inflates multiple air chambers 16, the one-way valve device automatically opens under the action of the airflow, and the pumping and inflation device 17 controls the airflow from the air chamber 16 relatively close to the pumping and inflation device 17 through the one-way valve device into the air chamber 16 relatively far away from the pumping and inflation device 17, thereby completing the inflation of the inflatable hull 14.

[0019] like Figure 2 As shown, after the inflation is completed, the one-way valve device is automatically closed by the air pressure in the air chamber 16 relatively far away from the pumping and inflating device 17, and the air in the two adjacent air chambers 16 cannot circulate through the one-way valve device.

[0020] like Figure 4 As shown, when the air pumping device 17 deflates multiple air chambers 16, the driving device controls the one-way valve device to move and open the one-way valve device. The air pumping device 17 controls the air flow from the air chamber 16 relatively far away from the air pumping device 17 through the one-way valve device into the air chamber 16 relatively close to the air pumping device 17, and then is discharged from the air pumping device 17 to complete the deflation of the inflatable hull 14.

[0021] The one-way valve device includes a bracket seat 3 fixed on one side of the shell 1, a sliding hole 4 is opened in the middle of the bracket 3, a sliding rod 8 is slidably arranged in the sliding hole 4, a plurality of charging and discharging holes 5 are opened on the bracket 3 outside the sliding hole 4, a card slot 6 is opened on the side of the bracket seat 3 away from the shell 1, a silicone umbrella valve 7 is arranged in the card slot 6, one end of the sliding rod 8 is fixedly connected to the silicone umbrella valve 7, and the other end of the sliding rod 8 cooperates with the driving device.

[0022] like Figure 3 As shown, when the pumping and inflating device 17 inflates multiple air chambers 16, the pumping and inflating device 17 controls the airflow to enter the air chamber 16 relatively close to the pumping and inflating device 17. Under the action of the airflow, the silicone umbrella valve 7 itself is deformed, and the outer side of the silicone umbrella valve 7 is separated from the card slot 6, and the inflation and discharge holes 5 are no longer sealed. The airflow in the air chamber 16 relatively close to the pumping and inflating device 17 passes through the inflation and discharge holes 5 and enters the air chamber 16 relatively far away from the pumping and inflating device 17, thereby completing the inflation of the inflatable hull 14.

[0023] like Figure 2 As shown, after the inflation is completed, the silicone umbrella valve 7 is restored to its original state by the air pressure in the air chamber 16 which is relatively far away from the pumping and inflating device 17, and the silicone umbrella valve 7 enters the card slot 6 and seals the charging and discharging holes 5, so that the air in the two adjacent air chambers 16 cannot circulate through the charging and discharging holes 5.

[0024] The driving device includes a driving motor 9, which is fixedly arranged inside the housing 1. A connecting rod 10 is fixedly arranged at the output end of the driving motor 9, and a toggle rod 11 is arranged on the connecting rod 10. A toggle groove 12 is provided at one end of the sliding rod 8 away from the silicone umbrella valve 7. The toggle rod 11 is movably arranged in the toggle groove 12 and contacts and cooperates with both ends thereof. The driving device also includes a control switch 13, which is electrically connected to the driving motor 9.

[0025] In this embodiment, preferably, the control switch 13 is disposed on the pumping and charging device 17 , and the opening and closing of the plurality of driving motors 9 can be controlled by the control switch 13 .

[0026] like Figure 4As shown, when the pumping and inflating device 17 deflates multiple air chambers 16, the output end of the driving motor 9 is controlled to rotate by the control switch 13, and the output end of the driving motor 9 drives the connecting rod 10 and the toggle rod 11 to rotate, and the rotating toggle rod 11 contacts the toggle groove 12 on the side close to the silicone umbrella valve 7, and drives the sliding rod 8 to move along the sliding hole 4, so that the silicone umbrella valve 7 is disengaged from the card slot 6, and the silicone umbrella valve 7 no longer seals the charging and discharging holes 5, and the airflow in the air chamber 16 relatively far away from the pumping and inflating device 17 passes through the charging and discharging holes 5 and enters the air chamber 16 relatively close to the pumping and inflating device 17, and then is discharged from the pumping and inflating device 17, completing the deflation of the inflatable hull 14. After deflation is completed, the output end of the motor 9 is driven by the control switch 13 to drive the connecting rod 10 and the toggle rod 11 to rotate, and the rotating toggle rod 11 contacts the toggle groove 12 away from the side of the silicone umbrella valve 7, and drives the slide rod 8 to move along the slide hole 4, so that the silicone umbrella valve 7 enters the card slot 6, and the silicone umbrella valve 7 seals the charging and discharging hole 5.
