Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vehicle-mounted liquid bag, and concretely relates to a vehicle compartment liquid bag facilitating rapid liquid discharge. BACKGROUND

[0002] With the rapid development of social economy and the increasing frequency of global trade, the logistics and transportation industry is facing higher efficiency and safety requirements. The vehicle compartment liquid bag, as an innovative liquid transportation solution, is gradually becoming an important part of the logistics chain. The vehicle compartment liquid bag is a flexible container for one-time use, usually made of high-strength, leak-proof materials such as polyethylene or polypropylene. Its design purpose is to safely and efficiently transport liquid goods from one place to another.

[0003] There are some problems when using the vehicle-mounted liquid bag. When the vehicle-mounted liquid bag is used to transport some high-viscosity liquids such as honey or thick lubricating oil, the high-viscosity liquid is more difficult to flow than the low-viscosity liquid such as water. This phenomenon directly affects the liquid discharge efficiency of the vehicle-mounted liquid bag, causing slow liquid discharge speed or even complete failure to discharge. Secondly, environmental factors also affect the liquid discharge speed, and temperature is an important factor affecting the viscosity of the liquid. The viscosity of the liquid usually increases with the decrease of temperature, resulting in a decrease in the liquid discharge speed. SUMMARY

[0004] Therefore, the utility model provides a vehicle compartment liquid bag facilitating rapid liquid discharge, which can solve the problem of slow liquid discharge speed of the existing vehicle compartment liquid bag.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a vehicle compartment liquid bag facilitating rapid liquid discharge, which comprises a liquid bag, a flexible diaphragm, a liquid discharge port assembly, a reinforcing rib, a lifting ring and a gas valve, wherein the liquid bag is in the shape of a flat rectangular cuboid structure and is used for containing liquid, the flexible diaphragm divides the internal space of the liquid bag into two chambers, one of which is used for storing liquid and the other of which is used for storing compressed gas, and the shape of the flexible diaphragm is matched with the shape of the internal cavity of the liquid bag.

[0007] The liquid discharge port assembly is fixedly installed at the lowermost position of the side wall of the liquid bag, the liquid discharge port assembly comprises a liquid discharge port, a quick connector and a sealing ring, and the liquid discharge port assembly is used for connecting external pipelines or equipment for liquid discharge;

[0008] The reinforcing rib is divided into an external reinforcing rib and an internal reinforcing rib, the external reinforcing rib is arranged along the height direction and the width direction of the liquid bag and is used for supporting the pressure in the vertical direction and the horizontal direction of the liquid bag, and the internal reinforcing rib is arranged inside the flexible diaphragm and is used for preventing the flexible diaphragm from being broken;

[0009] The lifting ring is arranged on the top of the liquid bag, and the lifting ring is slidably installed with the buckle of the top of the liquid bag, and the lifting ring is used for lifting and transporting the liquid bag.

[0010] The top of the liquid bag is provided with a liquid inlet.

[0011] The technical effects of the car compartment liquid bag for quick liquid discharge provided by the utility model are as follows: flexible diaphragm and compressed gas chamber: the flexible diaphragm in the liquid bag divides the liquid bag into a liquid chamber and a compressed gas chamber. By inflating the compressed gas chamber, pressure can be applied to the liquid chamber, thereby pushing the liquid to be discharged quickly, improving the liquid discharge efficiency and reducing residual liquid. This is more effective than relying on gravity or simple extrusion, especially in the case of needing to be quickly emptied or the liquid having high viscosity. The air pressure can extrude the liquid from all corners of the liquid bag, reducing the amount of residual liquid and improving the emptying efficiency; by controlling the inflation pressure, the liquid discharge speed can be adjusted to achieve precise control.

[0012] The design of the liquid discharge port assembly includes a quick connector and a liquid discharge valve, which can quickly connect external pipelines or equipment and accurately control the discharge of liquid, further improving the liquid discharge efficiency.

[0013] The design of the reinforcing ribs enhances the structural strength of the liquid bag, enabling it to withstand higher pressure and thus discharge liquid more quickly. The reinforcing ribs are used to enhance the structural strength and pressure resistance of the liquid bag, preventing the liquid bag from deforming or rupturing when filled with liquid.

[0014] When the compressed gas is filled into the compressed gas chamber, the flexible diaphragm will deform towards the liquid chamber, applying pressure to the liquid and thus pushing the liquid to flow quickly to the liquid discharge port. Due to the elasticity of the flexible diaphragm, it can recover to its original shape after the liquid is emptied, facilitating the reuse of the liquid bag.

[0015] On the basis of the above technical solutions, the car compartment liquid bag for quick liquid discharge of the utility model can also be improved as follows:

[0016] Among them, the flexible diaphragm is fixedly connected to the inner wall of the liquid bag, forming a sealed liquid chamber and a compressed gas chamber, and the gas valve is installed on the inflation port of the compressed gas chamber, used for controlling the filling and discharge of compressed gas to adjust the liquid discharge speed and pressure.

[0017] Further, the liquid discharge port assembly further includes a liquid discharge valve, which is a ball valve used to prevent accidental leakage of liquid, and the number of liquid discharge port assemblies is multiple and evenly arranged on the side wall of the liquid bag.

[0018] Further, the external reinforcing ribs are arranged in a sinusoidal pattern, and the internal reinforcing ribs are arranged in a grid pattern, so as to improve the overall strength and stability of the liquid bag.

[0019] Further, the liquid bag is made of high-strength, corrosion-resistant flexible polyvinyl chloride plastic.

[0020] Further, the liquid bag is coated with a layer of anti-sticking coating inside to prevent liquid from sticking to the inner wall of the liquid bag and improve the liquid discharge efficiency. The anti-sticking coating is made of Teflon material.

[0021] Further, the liquid bag is provided with a protective layer outside, which is made of polystyrene foam.

[0022] Further, the lifting ring is made of high-strength synthetic fiber material.

[0023] Further, the flexible diaphragm is made of elastic and airtight silicone rubber.

[0024] Further, the flexible diaphragm is made of high-strength fiber material.

[0025] Compared with the prior art, the liquid bag provided by the utility model has the beneficial effects that: the flexible diaphragm and the compressed gas chamber: the flexible diaphragm inside the liquid bag divides the liquid bag into a liquid chamber and a compressed gas chamber. By inflating the compressed gas chamber, pressure can be applied to the liquid chamber, thereby pushing the liquid to be discharged quickly, improving the liquid discharge efficiency and reducing residual liquid. This is more effective than relying on gravity or simple extrusion, especially in the case of needing to be quickly emptied or the liquid having high viscosity. The air pressure can extrude the liquid from all corners of the liquid bag, reducing the amount of residual liquid and improving the emptying efficiency; by controlling the inflation pressure, the liquid discharge speed can be adjusted to achieve precise control.

[0026] The design of the liquid discharge port assembly, including the quick connector and the liquid discharge valve, can quickly connect external pipelines or equipment and accurately control the discharge of liquid, further improving the liquid discharge efficiency.

[0027] The design of the reinforcing ribs enhances the structural strength of the liquid bag, so that it can withstand higher pressure and thus discharge liquid faster. The reinforcing ribs are used to enhance the structural strength and pressure resistance of the liquid bag, preventing the liquid bag from deforming or breaking when filled with liquid.

[0028] When the compressed gas is filled into the compressed gas chamber, the flexible diaphragm will deform towards the liquid chamber, applying pressure to the liquid and thus pushing the liquid to flow quickly to the liquid discharge port. Due to the elasticity of the flexible diaphragm, it can recover to its original shape after the liquid is emptied, facilitating the reuse of the liquid bag. BRIEF DESCRIPTION OF DRAWINGS
