Technical Field
[0001] This utility model belongs to the field of protective technology, specifically relating to a waterproof packaging container. Background Technology
[0002] During floods, cars in parking spaces and underground parking lots, as well as furniture and appliances, are submerged and floating in the water, creating a desolate and regrettable scene with huge losses. Current waterproofing measures simply involve wrapping items in waterproof bags. These items vary in size and shape, and when sealed, their overall density is less than water. As water levels rise, the sealed bags float and drift away with the current, or they may rupture and leak due to collisions, failing to achieve the intended waterproofing. Summary of the Invention
[0003] The purpose of this utility model is to provide a waterproof bag for use in automobiles, furniture, and appliances. The bag, which is sealed inside the vehicle, is connected and fixed to the ground by a connecting component, so that it does not float up with the rising water level or drift away with the current.
[0004] This utility model also provides a fluid discharge device for a waterproof bag, which prevents the waterproof bag from expanding due to the buoyancy of rising water after it is wrapped and sealed in a car, thus affecting vehicles next to the parking space, and also makes the waterproof bag suitable for installation in water.
[0005] The technical solution of this utility model is as follows:
[0006] A fluid discharge device for a waterproof bag includes a waterproof bag body, an electric fluid discharge component, and a connecting component. The device is characterized in that a one-way valve assembly is connected through the waterproof bag body, with the discharge end of the one-way valve assembly located outside the waterproof bag body and the inlet end located inside the waterproof bag body, thereby enabling the discharge of pressurized fluid from inside the waterproof bag body.
[0007] The device is characterized in that the connecting component is combined with the inner side and / or outer side of the waterproof bag body, and the connection point has a stepped hole; the one-way valve assembly passes through the stepped hole connecting the waterproof bag body. The connecting component is a connecting gasket, which does not have connecting elements. The connecting gasket is adhesively connected to the waterproof bag body, and the adhesive connection point has a stepped hole located at the top of the waterproof bag. The one-way valve assembly only allows fluid to flow unidirectionally from the inside to the outside of the waterproof bag.
[0008] The feature is that the one-way valve assembly access end extends to the bottom of the waterproof bag body, and its function is to allow the water to be discharged first and then the air to be discharged under pressure inside the waterproof bag, so that the waterproof bag is suitable for water-related installation applications.
[0009] The fluid discharge device is characterized by discharging in either a non-powered or electrically driven mode. In the non-powered mode, a pressure difference is created by the combined effect of the weight of the items inside the waterproof bag and the buoyancy of the water, causing the fluid inside the waterproof bag to be pressurized and discharged outwards. In the electrically driven mode, the fluid inside the waterproof bag is forcibly discharged through an electric fluid discharge component.
[0010] The one-way valve assembly is characterized by being connected to an electric fluid discharge component, or an electric fluid discharge component with a liquid level sensor, which automatically discharges fluid upon detecting a leakage risk.
[0011] A waterproof bag includes a waterproof bag body, an opening and closing component, and a fluid discharge device, characterized in that a connecting component is coupled to the inner side and / or outer side of the waterproof bag body, and the connecting component is anchored to an article inside the waterproof bag body and a fastener outside the waterproof bag body.
[0012] The feature is that the connecting component is coupled to the inner and outer sides of the waterproof bag, or the inner and outer sides of the waterproof bag, or between the inner and outer sides of the waterproof bag. The connecting component is a connecting gasket, which is adhesively connected to the inner or outer side of the waterproof bag, between the inner and outer sides, or between the inner and outer sides. The telescopic seal and the corrugated hose pass through the waterproof bag body, and their outer edges are adhesively connected to the waterproof bag body.
[0013] The feature is that the connecting component has a one-sided connecting structure or a two-sided connecting structure; wherein, the one-sided connecting structure is that the connecting component forms a mesh structure on the outside of the waterproof bag through the connecting element; the two-sided connecting structure is that the connecting component simultaneously connects the items inside the waterproof bag and the fixings outside the waterproof bag through the connecting element, and the connecting component and the connecting element are integrally formed, built-in, or fixedly connected. The one-sided connecting structure is as follows: the connecting component is a connecting gasket, each connecting gasket has one side connected to the inner and / or outer side of the waterproof bag, and the other side connected to one connecting element. The 12 connecting gaskets are respectively connected to the top outer surface and both sides of the waterproof bag, and the connecting elements of these connecting gaskets are interconnected to form a mesh structure. This mesh structure is used to anchor and fix the waterproof bag to the fixings of the parking space. The two-sided connecting structure is as follows: the connecting component is a connecting gasket, and each connecting gasket has one connecting element on each of its two sides. The outer edge of the connecting gasket is attached to the wall of the waterproof bag. One side of the gasket has a connecting element for anchoring items inside the waterproof bag, while the other side has a connecting element for connecting to external fasteners. In this way, the four connecting gaskets can simultaneously secure the inside and outside of the waterproof bag. The connection between the connecting parts and connecting elements includes, but is not limited to, integral molding, built-in, or fixed connections. The connecting elements include, but are not limited to, rigging, shackles, or buckles. The rigging includes, but is not limited to, ropes, wire ropes, or chains. When the connecting part is a connecting gasket, it does not have a connecting element when connected to the one-way valve assembly.
[0014] The connecting component is characterized by being any one of the following: a connecting gasket, a telescopic seal, a corrugated hose, or the extended cavity of the waterproof bag. The connecting gasket may have a one-sided or two-sided connecting structure. The telescopic seal, corrugated hose, or extended cavity of the waterproof bag may have a two-sided connecting structure. The connecting component can only employ one of either a one-sided or two-sided connecting structure; it cannot possess both structures simultaneously.
[0015] The waterproof bag is characterized by being applied to automobiles, specifically as a car waterproof bag. The opening and closing component is used to open or close the waterproof bag body. This component is connected to the edge of the opening of the waterproof bag body. The opening and closing component, corresponding to the car interior, is configured in any of the following ways: horizontally positioned above the front bumper; horizontally positioned below the rear trunk lid; vertically positioned along the roof centerline; vertically positioned from the front to the rear of the car near the window edge; surrounding the car body at the tire contact patch; surrounding the car body at the lower edge of the window frame; or surrounding the car body at the junction of the tire upper edge and the fender. The opening and closing component divides the waterproof bag body into a top cover and a bottom cover, which can be closed to form a sealed waterproof bag body. The top cover can be used independently as a car cover; or a parking space can be used as a component that cooperates with the top cover to achieve a sealing function, with the parking space and the top cover forming a sealed waterproof bag body.
[0016] The feature is that the opening and closing component includes a zipper, a drawstring sealing structure, or a magnetic sealing structure. The zipper includes an airtight zipper or a watertight zipper. The teeth of the airtight zipper are respectively connected to the two sides of the waterproof bag opening, and the two teeth match each other, sealing the waterproof bag body. The drawstring sealing structure involves rolling the edge of the waterproof bag opening inward and sewing it in place, forming a small cavity around the bag opening. This small cavity serves as a drawstring channel, through which a drawstring is threaded. Pulling the drawstring causes the waterproof bag opening to contract and seal. The magnetic sealing structure consists of magnetic sheets connected to both sides of the waterproof bag opening. These magnetic sheets are matched to each other, and when the waterproof bag opening is closed, the magnetic sheets attract each other magnetically, thus sealing the waterproof bag opening. To prevent the magnetic sheets from adhering to the car surface, each magnetic sheet is covered with a non-magnetic isolation layer. When sealing is required, the two magnetic sheets are aligned, and the isolation layer is removed, causing the magnetic sheets to attract each other, thereby sealing the waterproof bag. The magnetic sheets include flexible neodymium iron boron soft magnetic sheets, which have good flexibility and strong magnetism, ensuring sealing performance.
[0017] The waterproof bag is characterized by having a polyurethane elastic transparent sheet attached to its side, which is sufficient to cover the license plate area inside the waterproof bag, making it easy to see the license plate from the outside.
[0018] The waterproof bag is characterized by having a protective pad around its outer perimeter, which is fixed to the outside of the waterproof bag by Velcro or rope.
[0019] The size and thickness of the connecting gasket are determined according to the needs of the contact area. By reasonably balancing the appropriate size and thickness, the impact of the size and thickness on the core technical effect and the realization of the invention objective is minimal. For example, the size of the gasket located under a car tire needs to be determined according to the size of the tire. In the description of this utility model, it should be noted that the terms "through connection," "pipe connection," and "joint connection" should be interpreted broadly. For example, the through connection can be a through-and-adhesive connection or a through-and-adhesive connection; the joint connection can be a sewn-on connection, a fusion connection, or an adhesive connection; the pipe connection can be a spiral joint connection, a thermoplastic bonding connection, a socket connection, or a snap-fit connection; it can also be an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Attached Figure Description

[0032] As shown in Figure (1), the connecting component is connected to the inner side and / or outer side of the waterproof bag body. The connecting component is a connecting gasket 7, which does not include the rigging 8. The one-way valve assembly 3 penetrates the waterproof bag body 6 and is connected to the connection point between the connecting component and the waterproof bag body. The connecting gasket 7 is circular, with a thickness not exceeding 5 times the thickness of the waterproof bag body, and a diameter of 5 cm to 10 cm. The connecting gasket 7 is made of soft, elastic material. The connecting gasket 7 is connected to the inner side and / or outer side of the waterproof bag body 6. A stepped hole 22 is opened at the connection point. The stepped hole 22 consists of two holes of different diameters, one large and one small, which are glued and overlapped to form a two-layer stepped structure. The large hole and the small hole are coaxial, and the small hole is located at the center of the large hole. The waterproof bag body first has a large hole, which matches the outer edge of the one-way valve assembly 3. Then, the connecting gasket 7 covers and connects beyond the large hole. After the connecting gasket 7 covers the large hole, a small hole is made on the connecting gasket 7, coaxial with the large hole. The small hole is smaller than the outer edge of the one-way valve assembly 3, and the diameter difference between the large hole and the small hole is 0.5 cm to 1 cm. The one-way valve assembly 3 penetrates the waterproof bag body 6 and passes through and connects to the stepped hole 22 of the waterproof bag body 6, and is then glued and sealed. Because the connecting gasket 7 has elasticity, it can better fit and seal the one-way valve assembly 3, enhancing the tightness of the through-connection. The connection between the waterproof bag body 6, the connecting gasket 7, and the one-way valve assembly 3 enhances the stability and sealing of the connection between the waterproof bag body and the one-way valve assembly 3. The discharge end of the one-way valve assembly 3 is located outside the waterproof bag body, while its inlet end is located inside the waterproof bag body 6. The combined effect of the weight of the items inside the waterproof bag and the buoyancy of the water creates a pressure difference, which drives the fluid inside the waterproof bag to be pressurized and discharged outwards. Furthermore, the inlet end of the one-way valve assembly 3 extends to the bottom inside the waterproof bag. When the waterproof bag is installed in water, if there is water accumulation inside the waterproof bag, the pressure inside the waterproof bag will first discharge the accumulated water and then discharge the air. The fluid can be water or air.
[0033] As shown in Figure (6), the opening and closing component is a drawstring sealing structure 16. A drawstring channel is provided around the edge of the waterproof bag opening. The drawstring sealing structure 16 is formed by rolling the edge of the waterproof bag opening inward and sewing it in place, forming a small cavity around the waterproof bag opening as a drawstring channel. A rope is threaded through the drawstring channel. By pulling the rope, the waterproof bag opening can be contracted and sealed. As shown in Figure (12), the opening and closing component is a magnetic sealing structure 29. The magnetic sealing structure 29 consists of magnetic sheets 30 connected to both sides of the opening of the waterproof bag. The magnetic sheets match each other. When the opening of the waterproof bag is closed, the two magnetic sheets 30 attract each other through magnetic force, thereby sealing the opening of the waterproof bag. To prevent the magnetic sheets from adsorbing onto the car surface, the magnetic sealing structure 29 is equipped with a non-magnetic isolation layer sleeve. Each of the magnetic sheets 30 on both sides of the opening of the waterproof bag is fitted with a non-magnetic isolation layer sleeve. The non-magnetic isolation layer sleeve is made of plastic and matches the size of the magnetic sheet 30. When sealing is required, the magnetic sheets on both sides of the waterproof bag are aligned, and the isolation layer sleeve is pulled out so that the magnetic sheets attract each other, thereby sealing the waterproof bag. The magnetic sheets include flexible neodymium iron boron soft magnetic sheets, which have good flexibility and strong magnetism, and can ensure the sealing of the waterproof bag. Detailed Implementation
[0034] This utility model of a waterproof bag is applicable to furniture, appliances, and vehicles. When water levels rise, water enters the car. At this time, the overall density of the car and water is greater than that of water, so the car will not float. However, when the waterproof bag seals the car, no water enters. At this time, the overall density of the car is less than that of water, so the car will float when water levels rise. Therefore, to prevent water damage, it is necessary to secure the car inside the waterproof bag to a parking space. Because the weight of the car inside the waterproof bag, the buoyancy of the water, or the scouring effect of the water flow can easily cause tearing and leakage at the fixing joints, it is necessary to use a specific connection and fixing method. To make the purpose, technical solution, and advantages of this utility model clearer, the following detailed description, using a car as an example, is provided in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.
[0035] Implementation Case 1
[0036] As shown in Figures (1) and (11), the fluid discharge device 1 is a one-way valve assembly 3 that penetrates the waterproof bag body. The one-way valve assembly 3 penetrates the stepped hole 22 of the waterproof bag body. The one-way valve assembly 3 is a flexible round tube connected to the one-way valve 2 by a pipe connection. The one-way valve assembly only allows fluid to flow unidirectionally from the inside of the waterproof bag to the outside. The pipe connection includes socket connection and spiral joint connection. One end of the one-way valve assembly 3 is the flexible round tube, and the other end is the one-way valve 2. The inlet end of the one-way valve assembly 3 is the flexible round tube, and the outlet end of the one-way valve assembly 3 is the one-way valve 2. The length of the elastic tube is sufficient to reach the bottom of the waterproof bag. The inlet of the one-way valve assembly 3 is located inside the waterproof bag, extending naturally to the bottom of the waterproof bag, or the inlet of the one-way valve assembly 3 is connected and fixed to the bottom of the waterproof bag with a pipe clamp. The outlet of the one-way valve assembly 3 is located outside the waterproof bag, which is the outer side of the waterproof bag. A stepped hole 22 is opened at the top of the waterproof bag, and the outlet of the one-way valve assembly 3 passes through the stepped hole 22 and is sealed by adhesive. The one-way valve 2 consists of a shell, a valve seat, a spring, and a valve core. The valve core 25, the spring 30, and the valve seat 27 are fixedly connected inside the shell. One end of the spring 26 is fixedly connected to the valve seat 27, and the other end of the spring 26 is fixedly connected to the valve core 25. The valve core 25 seals the fluid passage of the one-way valve 2 under the elastic force of the spring 26. The valve seat 27 has a hole in the middle as the discharge end. The valve core 25 and the spring 26 of the one-way valve 2 jointly control the fluid flow direction. When the fluid flows in the forward direction, the fluid pressure overcomes the spring force and pushes the valve core 25 to open, allowing the fluid to pass smoothly through the fluid passage. When the fluid flows in the reverse direction, the valve core 25 closes the one-way valve 2 under the combined action of the spring force and the reverse fluid pressure, preventing the fluid from flowing in the reverse direction. The valve core is used to open or close the one-way valve 2, and the spring is used to help the valve core close the one-way valve 2 quickly. The fluid overcomes the elastic force of the valve core and spring to push open the valve core and discharge outward. The fluid is discharged outward through the one-way valve assembly 3 under the pressure inside the waterproof bag. When the pressure is released, the valve core closes the one-way valve assembly 3 under the action of the spring to prevent fluid backflow. As the water level rises, the waterproof bag is submerged. The weight of the items inside the bag exerts downward pressure, while the buoyancy of the water acts upward on the bag. This interaction creates a pressure difference, generating additional pressure inside the bag. This pressure compresses the fluid within, driving it to be discharged through the one-way valve assembly 3. A one-way valve 2 prevents backflow. This process is completed as the water level gradually rises. The fluid is air.The one-way valve assembly 3 extends to the bottom of the waterproof bag body, and a filter screen is provided at the port. When the waterproof bag is installed in water, water accumulates inside. As the water level rises, the pressure difference gradually increases. The water inside the waterproof bag preferentially enters through the one-way valve assembly and then exits outward. After the water is discharged, air is also discharged. The discharge component 1 automatically discharges the fluid outward. The discharge method of the discharge component 1 is a non-powered discharge mode.
[0037] Optionally, as shown in Figures (2) and (11), the one-way valve assembly 3 is connected to an electric fluid discharge component, or an electric fluid discharge component with a liquid level sensor. The electric fluid discharge component includes a pipe exhaust fan 4 and a water pump 5. Each of the pipe exhaust fan 4 and the water pump 5 is connected to one of the one-way valve assemblies 3, and the connection method is a pipe connection. The pipe exhaust fan 4 and the water pump 5 are a miniature pipe exhaust fan and a miniature water pump. The pipe exhaust fan 4 and the water pump 5 are fixedly connected together by a plastic connector 17. The plastic connector 17 has a cavity inside suitable for installing the pipe exhaust fan 4 and the water pump 5. The fixed connection is a self-tapping screw connection. The plastic connector 17 is a trapezoidal shell. The top of the plastic connector 17 is connected to the top of the waterproof bag body. The pipe exhaust fan 4 and the water pump 5 are fixedly connected inside the trapezoidal shell. The water pump 5 has an outlet and an inlet. The inlet of the one-way valve assembly 3 is connected to the outlet of the water pump 5, and the inlet of the water pump 5 is connected to a section of flexible round pipe. The connection method is a pipe connection, and the inlet end of the flexible round pipe is located at the bottom of the waterproof bag body. The duct-type exhaust fan 4 has an outlet and an inlet. The inlet of the one-way valve assembly 3 is connected to the outlet of the duct-type exhaust fan 4. The connection method is a pipe connection, and the inlet of the duct-type exhaust fan 4 is located on the car hood inside the waterproof bag body. The top of the waterproof bag body has two stepped holes 22. The discharge ends of the two one-way valve assemblies 3 pass through and connect to the two stepped holes 22. The discharge ends of the duct-type exhaust fan 4 and the water pump 5 are located outside the waterproof bag body. The outside of the waterproof bag body is the outer side of the waterproof bag body. The duct-type exhaust fan 4 and the water pump 5 are located inside the waterproof bag body. A control switch 23 is fixedly connected between the discharge ends of the two one-way valve assemblies 3 to control the duct-type exhaust fan 4 and the water pump 5. The control switch 23 is located on the outside of the waterproof bag. The duct-type exhaust fan 4 and the water pump 5 are connected to the control switch 23 and the vehicle power supply to control the opening and closing of the duct-type exhaust fan 4 and the water pump 5. The fluid is water or air. When the waterproof bag is installed in water, water accumulates inside the waterproof bag. The control switch controls the water pump 5 to force the water out. When the water pump 5 is working, the pump body generates negative pressure. The inlet of the water pump 5 is connected to the elastic round tube located at the bottom of the waterproof bag. The water accumulated at the bottom of the waterproof bag enters the pump body under the action of negative pressure and is then discharged outside the waterproof bag. The control switch controls the duct-type exhaust fan 4 to force the air out of the waterproof bag, and a one-way valve 2 prevents water and air from flowing back into the waterproof bag.The discharge device 1 operates in an electrically driven mode. The fluid discharge device 1 prevents the waterproof bag 6 from expanding due to rising water levels, thus avoiding impact on nearby vehicles, and also reduces buoyancy caused by rising water levels by expelling excess air. When installing the waterproof bag in wading, the fluid discharge device 1 facilitates the timely drainage of water entering the bag, creating favorable conditions for securing the car inside the bag in the parking space and simplifying the installation and application of the waterproof bag. Optionally, the electric fluid discharge component's pump is equipped with a liquid level sensor, such as DLK201 or PY201. The inlet of the electric fluid discharge component and the liquid level sensor are fixed to the bottom of the waterproof bag, and the liquid level sensor is used to monitor changes in the liquid level inside the waterproof bag in real time. When liquid is detected inside the waterproof bag, the pump is triggered to start, draining the accumulated water and preventing accidental leakage that could soak the car chassis. The liquid level sensor in the water pump utilizes mature and widely used technology. The fluid discharge device simply combines the function of the liquid level sensor with the water pump. The liquid level sensor itself is outside the scope of this invention. However, the combined use of the electric fluid discharge component with the liquid level sensor and the waterproof bag adds an important protective measure to the waterproof bag. The duct-type exhaust fan, water pump, and liquid level sensor are purchased accessories. Their structural functions will not be detailed here, as these are common knowledge to those skilled in the art.

[0040] The waterproof bag body 6 is connected to a connecting component on its outer side. This connecting component is a connecting gasket 7, and the waterproof bag is connected to 4 or 12 connecting gaskets. Taking 12 connecting gaskets as an example: the 12 connecting gaskets 7 are connected to the top outer surface of the waterproof bag body 6 and the two outer sides of the waterproof bag body 6, corresponding to the sides and top of the vehicle inside the waterproof bag body 6. The connection includes sewing, bonding, and fusion. The connecting gasket 7 is a circular, elastic gasket made of wear-resistant and pressure-resistant material, with a thickness not exceeding 5 times the thickness of the waterproof bag body 6, and a diameter of 5 cm to 10 cm. One side of the connecting gasket 7 is connected to the rigging 8, and the other side of each of the 12 connecting gaskets 7 is connected to the rigging 8. The connection is either riveting or integral molding. The integral molding is achieved by injection molding or glue injection. The rigging 8 on the 12 connecting gaskets 7 are interwoven to form a mesh-like structure. This mesh structure is then connected to four fixing members 9 on the parking space by other rigging. This connection is a binding connection. The mesh structure and the fixing members 9 form a reliable mechanical connection system to effectively secure the car inside the waterproof bag 6. The four fixing members 9 are distributed around the parking space. This connection facilitates uniform force distribution and improves the stability and reliability of the connection. The fixing members 9 are anchor bolts, which are fastened to the surface of the parking space 24.
[0041] Optionally, as shown in Figure (3), the bottom of the waterproof bag 6 is connected to four connecting gaskets 7, corresponding to the area under the car tire inside the waterproof bag 6. The connecting gaskets 7 are rectangular, with a width equivalent to the width of the car tire and a length equivalent to the tire diameter. The connecting gaskets 7 are connected to the inside or outside of the waterproof bag 6. The bottom of the waterproof bag 6 has four bottom holes 20. The connecting gaskets 7 are connected to the outside of the waterproof bag 6. One side of the connecting gasket 7 is connected to a rigging 8, which passes through the bottom hole 20 and enters the waterproof bag 6. The rigging 8 is connected to the car tire. The other side of the connecting gasket 7 is connected to a rigging 8, which is connected to a fastener 9 outside the waterproof bag 6. The connection is a binding connection. Similarly, the connecting gasket 7 is connected to the inside of the waterproof bag body 6. A rigging 8 connected to one side of the connecting gasket 7 passes through the bottom hole 20 and exits the outside of the waterproof bag body 6. The rigging 8 is connected to the fixing member 9. The rigging 8 connected to the other side of the connecting gasket 7 is connected to the tires of the car inside the waterproof bag body 6.

The rigging 8 is connected to the four tires of the car. The rigging 8 connected to the other side of the four connecting gaskets 7 is connected to the four fixing members 9 on the parking space outside the waterproof bag body 6. Alternatively, the waterproof bag body 6 does not require openings. Two connecting gaskets 7 are used to securely bond one on the inner side and one on the outer side of the waterproof bag body 6 at the same corresponding position, forming a single connecting gasket. A small hole is made at the joint, and rigging 8 is connected using riveting or bolts. Rigging 8 is connected to both sides of the connecting gasket 7. The rigging 8 connected to both sides of the connecting gasket anchors the car tire inside the waterproof bag to the fixing components in the parking space.

[0051] This utility model of waterproof bag can be applied to furniture, appliances, and vehicles, with its shape and size determined according to the required dimensions of the items being used. For example, when applied to a car, the waterproof bag is rectangular in shape, and the bag body 6 is larger than the car, easily covering the entire vehicle. The opening and closing mechanism is used to open or seal the waterproof bag body 6, and the opening and closing mechanism can be an airtight zipper 15, a drawstring sealing structure 16, or a magnetic sealing structure 29. The waterproof bag body 6 has an opening and closing component located in any of the following positions: horizontally above the front bumper; horizontally below the rear trunk lid; vertically along the roof centerline; vertically from the front to the rear near the window edge; around the tire contact area; around the lower edge of the window frame; around the tire at the junction with the fender. The bottom of the waterproof bag body 6 has an airtight zipper 15 that divides the waterproof bag body 6 into a top cover 13 and a bottom cover 14. The bottom cover 14 extends to the upper edge of the tire and the boundary of the fender inside the waterproof bag body 6 or to the lower edge of the window frame. Optionally, the surface of the parking space 24 serves as a component that can be matched and sealed with the top cover 13, forming a sealed waterproof bag body 6 with the top cover 13. There are three ways in which the connecting component secures or connects the car inside the waterproof bag 6 to the parking space: 1. Twelve connecting pads 7 are connected to the top outer surface or outer side of the waterproof bag 6. One side of each connecting pad 7 is provided with a rigging 8. The twelve connecting pads 7 are connected to each other through the rigging 8 to form a mesh-like structure. The twelve rigging ribs of the twelve connecting pads are interwoven in a certain pattern to form a mesh structure. The mesh structure is then connected to four fixing components of the parking space by additional rigging. The mesh structure is used to secure the car inside the waterproof bag 6. 2. Four connecting gaskets 7 are connected to the inner and / or outer sides of the bottom of the waterproof bag body 6. Each of the four connecting gaskets 7 has a rigging 8 connected to both sides. One rigging 8 passes through the bottom hole 20 into the interior of the waterproof bag body 6 and connects to the four tires of the car inside the waterproof bag body 6. The other rigging 8 is located outside the waterproof bag body 6 and connects to four fixing members 9 in the parking space. 3. The connecting components are a telescopic seal 10, a corrugated hose 11, and a waterproof bag extension cavity 12. The four telescopic seals 10 are connected to the bottom of the waterproof bag body 6 corresponding to the four tires of the car. Each telescopic seal 10 has a rigging 8 connected to both sides. One rigging 8 is located outside the waterproof bag body 6 and connects to the four fixing members 9 in the parking space. The other rigging 8 passes through the side hole 21 into the waterproof bag body 6 and connects to the four tires of the car.The connection method of the corrugated hose 11 and the waterproof bag extension cavity 12 is the same as the connection method of the telescopic seal.
[0052] The waterproof bag body 6 is equipped with a fluid discharge device 1, which is connected to the inside and / or outside of the waterproof bag by the one-way valve assembly 3. The discharge end of the one-way valve assembly 3 is located outside the waterproof bag, and the inlet end is located inside the waterproof bag, extending to the bottom of the waterproof bag. The weight of the items inside the waterproof bag and the buoyancy of the water work together to form a pressure difference. This pressure difference drives the fluid inside the waterproof bag to be pressurized and discharged outwards, and a one-way valve 2 prevents the fluid from flowing back. Optionally, the one-way valve assembly 3 is connected to an electric fluid discharge component, which is a water pump 5 and a pipe-type exhaust fan 4. The fluid discharge device 1 forces the fluid outwards from inside the waterproof bag through the electric fluid discharge component, and a one-way valve 2 prevents the fluid from flowing back. The fluid is water or air. The fluid discharge device can be driven in a non-powered mode or an electric mode. The waterproof bag body 6 is surrounded by a protective pad, which corresponds to the front, sides, and rear of the car inside the waterproof bag. The waterproof bag application process involves folding and placing the waterproof bag under the car chassis. Then, using a lifting device, the car is lifted so that the waterproof bag unfolds and wraps upwards from the chassis, or the waterproof bag is opened and laid flat on the ground. The car is then driven into the opening of the waterproof bag, and the waterproof bag is spirally wrapped upwards from the chassis along the car body. The four inner straps 8 of the waterproof bag are connected and secured to the four tires of the car, and the four outer straps 8 of the waterproof bag are connected to four fasteners 9 on the parking space 24. The fluid discharge device 1 is then placed on the car hood and connected to the car's power supply. The car is then sealed using an opening and closing mechanism. The fluid discharge device 1 has a control switch 23, which controls a water pump 5 and a duct-type exhaust fan 4 to forcefully expel air and water from inside the waterproof bag body 6. Finally, a protective pad is attached to the outside of the waterproof bag body 6.
[0053] Beneficial effects
[0054] This invention discloses a fluid discharge device for a waterproof bag, featuring both a non-powered and an electric-powered mode. In the non-powered mode, a pressure difference is created by the combined effect of the weight of the contents inside the waterproof bag and the buoyancy of the water, driving the fluid inside the bag to be discharged outwards. When there is water inside the waterproof bag, the water is discharged first, followed by the air. This device prevents the waterproof bag from expanding due to pressure, avoiding the risk of collisions or scratches to adjacent vehicles in narrow parking spaces, while also reducing buoyancy. In the electric-powered mode, the water and air are forcibly discharged by connecting an electric fluid discharge component, making it particularly suitable for use in wading environments when water levels are rising. Furthermore, the water pump of the electric fluid discharge component is equipped with a liquid level sensor. When a liquid leak is detected, the water pump automatically starts to discharge the water, preventing accidental leakage from the waterproof bag from flooding the car chassis and providing additional safety assurance for the application of the waterproof bag.
[0055] This utility model discloses a waterproof bag and fluid discharge device that connects a car tire inside the waterproof bag to a fixing device in a parking space via connecting components. This not only secures the car to the parking space but also prevents the waterproof bag from tearing under the influence of gravity, buoyancy, and the traction force of the rigging. The waterproof bag is connected by 12 connecting components to form a mesh structure, which secures the car inside the waterproof bag to the parking space. This multi-point connection method facilitates even force distribution. The connecting components connect the inner and / or outer sides of the waterproof bag. Each connecting component has connecting elements on both sides, which connect the car tire inside the waterproof bag to the fixing device in the parking space outside the waterproof bag. The connecting components and connecting elements are, but are not limited to, integrally formed, internally installed, or fixedly connected, maintaining both the sealing of the waterproof bag and the stability and reliability of the connection. The connecting components can be telescopic seals, corrugated hoses, or extension cavities of the waterproof bag. All telescopic seals, corrugated hoses, or extension cavities of the waterproof bag are connected to the car tire inside the waterproof bag and the fixing device in the parking space via rigging. The connecting component secures the items inside the waterproof bag to the external fixing element via connecting elements, effectively preventing the waterproof bag from floating as the water level rises, while ensuring the bag's sealing and stability. The connection has an elastic cushioning effect, preventing the waterproof bag from tearing and leaking. The fluid discharge device works in conjunction with the waterproof bag, facilitating its installation and application, especially suitable for water-related installations. It also securely holds the car inside the waterproof bag in the parking space, effectively preventing the car from floating, rupturing, or drifting away with the current when the water level rises. Moving or raising cars and other large items to prevent water damage during rising water levels is a challenging task. This invention, through innovative design, effectively solves this problem, providing efficient and reliable waterproof protection for cars and other large items, significantly reducing the risk of water damage.
