[0002] In situations such as field work or camping, when taking water from a stream or a puddle, water containers such as buckets or water bottles are generally used. When the operator's arm can reach the water surface, the operator can conveniently take water. When the water surface height is lower than the reach of the human arm and it is difficult to smoothly take water, if a bucket or a water bottle is hung by a rope and immersed in the water to take water, since the upper end of the bucket or the water bottle is open and the lower end has a bottom plate, generally the lower half is heavier, so its center of gravity is generally above 1 / 2 of its height, that is, the center of gravity is relatively high. Also, since the density of the bucket or the water bottle itself is generally less than that of water, when the bucket or the water bottle hanging in contact with the water surface, due to the buoyancy force, in the case where the bucket or the water bottle is not filled with water, it is difficult for the bucket or the water bottle to be completely immersed in the water, resulting in difficulty in taking water. Therefore, a more effective and portable water intake device is needed. Summary of the Utility Model

Detailed implementation manners

[0029] The following specifically describes the portable water drawing device of the present application with reference to the accompanying drawings.

[0030] Please refer to Figure 1 , a portable water drawing device, including a water bag 100 and a base 200.

[0031] The mass of the base 200 is greater than the mass of the water bag 100 to maintain a lower center of gravity and is not easily overturned.

[0032] The density of the base 200 is greater than that of water, so that the base 200 can quickly sink into the water when drawing water.

[0033] The average density of the portable water drawing device is greater than that of water, so that the whole can sink into the water when drawing water.

[0034] The water bag 100 includes a bag body 101, an upper cover 102, a lower ring 103 and a tied member 104. The bag body 101, the upper cover 102 and the lower ring 103 are all preferably cylindrical. The lower ring 103 is a ring body with a hollow structure. The upper cover 102, the lower ring 103 and the tied member 104 are all preferably made of rigid materials. Both the upper end and the lower end of the bag body 101 are open; the upper cover 102 is seamlessly connected to the upper end of the bag body 101; the upper cover 102 has an air hole 1021; the lower ring 103 is seamlessly connected to the lower end of the bag body 101; the tied member 104 is installed on the upper cover 102; the tied member 104 has a point for connecting a rope; the lower ring 103 is provided with a first connection structure 1031.

[0035] The base 200 includes a seat body 201 and a check valve 202. The seat body 201 is preferably cylindrical. The seat body 201 has a water storage tank 2011 with an open upper end; the check valve 202 is installed at the bottom of the seat body 201; the allowable water flow direction of the check valve 202 is from outside the seat body 201 towards the water storage tank 2011, and the blocking water flow direction of the check valve 202 is from the water storage tank 2011 towards outside the seat body 201; the base 200 is provided with a second connection structure 2012.

[0036] It is possible that the first connection structure 1031 is an internal thread, and the second connection structure 2012 is an external thread. The internal thread matches the external thread, so that the water bag 100 and the base 200 can be conveniently connected and disassembled.

[0037] After the first connection structure 1031 is connected to the second connection structure 2012, the bag body 101 communicates with the water storage tank 2011. The center of gravity of the portable water pumping device is located within the lower 1 / 3 section of the total height of the unfolded water bag 100 and the base 200. A low center of gravity is not easily overturned.

[0038] When using the above-mentioned portable water pumping device to draw water, the water bag 100 and the base 200 are connected and fixed, and the air hole 1021 of the upper cover 102 is kept open. The portable water pumping device is placed in water, and the base 200 can quickly sink into the water. Water enters the water storage tank 2011 through the check valve 202 and then enters the bag body 101. The portable water pumping device can quickly sink completely into the water, making it convenient to draw water.

[0039] The bag body 101 is preferably an axially foldable cylindrical structure, and the axis is the height direction of the cylindrical structure. The bag body 101 includes a flexible cylindrical film 1011, and the cylindrical film 1011 is preferably cylindrical. The bag body 101 further includes one or more rigid rings 1012, and each rigid ring 1012 is embedded in the cylindrical film 1011 along the circumferential direction of the cylindrical film 1011. The cylindrical film 1011 between the rigid rings 1012, or the cylindrical film 1011 between the rigid ring 1012 and the upper cover 102 and the lower ring 103 can be folded for convenient storage. It should be understood that the cylindrical film 1011 is waterproof.

[0040] The portable water pumping device may further include a plugging assembly 105. The plugging assembly 105 includes a soft plug and a thin strip. The soft plug is fixed to one end of the thin strip, and the other end of the thin strip is fixed to the upper cover 102. The soft plug can completely close the air hole 1021. The air hole 1021 can be opened when drawing water, and can be closed when storing the device filled with water.

[0041] The tied member 104 can be a linear handle. Both ends of the handle are fixed to the upper cover 102.

[0042] Please refer to Figure 2 , the portable water pumping device may further include a lifting rope 300. The lifting rope 300 is tied to the handle, and hereinafter, the lifting rope 300 is used to control the portable water pumping device to draw water and discharge water.

[0043] The base 200 may further include a water faucet 203. The water faucet 203 is installed on the side wall of the seat body 201. The water inlet end of the water faucet 203 communicates with the water storage tank 2011, and the water outlet end is located outside the seat body 201. When water is needed, the water faucet 203 is opened to take out the water inside the device.

[0044] To further improve the connection sealing performance between the seat body 201 and the lower ring 103, a sealing ring 204 is embedded in the upper end surface of the seat body 201, and a blocking ring 1032 perpendicular to the inner peripheral wall is integrally provided on the inner peripheral wall of the lower ring 103. Connecting the seat body 201 to the lower ring 103 enables the sealing ring 204 to seamlessly abut against the blocking ring 1032, so that the seat body 201 and the lower ring 103 form a seamless connection. Thus, the sealing performance between the seat body 201 and the lower ring 103 is further improved.

[0045] The base 200 further includes a plurality of identical feet 205, such as 3 or 4 feet 205, which are all fixed on the outer bottom surface of the seat body 201; the centers of gravity of the plurality of feet 205 are located at the center of the outer bottom surface of the seat body 201; the same perforations 2051 are provided at the same positions of each foot 205. The feet 205 can support the device for easy placement, and the perforations 2051 of the feet 205 can also hang heavy objects 500 to increase the speed at which the device sinks into the water and improve the water intake speed.

[0046] Please refer to Figure 3 , the portable water pumping device may include a hanging rope 400 and a heavy object 500. The hanging rope 400 passes through each perforation 2051, and the hanging rope 400 is connected to the heavy object 500; the density of the heavy object 500 ≥ the density of the base 200. Hanging the heavy object 500 on the perforations 2051 of the feet 205 further increases the speed at which the device sinks into the water and improves the water intake speed.

[0047] The base 200 further includes a filter screen 206, and the filter screen 206 covers the outer end inlet of the check valve 202. The filter screen 206 can prevent large particles from entering the device.

[0048] The following are several working states of the portable water pumping device.

[0049] 1. Water entry process: Open the soft plug to make the air hole 1021 ventilable, release the lifting rope 300, and let the device contact the water surface in a vertical state. At this time, the heavy object 500 hanging on the feet 205 can preferably keep the device from tilting.

[0050] 2. Water drawing process: Continue to release the lifting rope 300. The heavy object 500 guides the device to continue sinking while ensuring that the device does not tilt. During the sinking process, the internal water pressure of the device is less than the external water pressure, and the check valve 202 opens. Water flows into the device after passing through the filter screen 206.

[0051] 3. Water discharging process: After the device is full of water, lift the lifting rope 300 to drive the device to rise and keep it in a vertical state. When the internal water level is higher than the external water level, the internal water pressure is greater than the external water pressure, and the check valve 202 automatically closes, so that water will not flow out of the device.

[0052] 4. Transportation process: Cover the air hole 1021 with a soft plug, and the device can be carried by hand or placed on a vehicle for transportation. Since the bag body 101 is an axially foldable cylindrical structure, under the pressure of the upper cover 102, the bag body 101 has a tendency to fold axially (i.e., vertically), and it is not easy to tilt, so that the device remains in a vertical state during this process.

[0053] 5. Water using process: Hang the device by the handle or place it through the support feet 205, open the soft plug to ventilate the air hole 1021, and water can be taken through the faucet 203. The device remains in a vertical state during this process.

[0054] 6. Storage process: Drain the water in the device through the faucet 203, remove the water bag 100 from the base 200, pour out the remaining water in the base 200, and then it can be stored in a smaller volume. Under appropriate conditions, the water bag 100 and the base 200 can be cleaned separately.

[0055] The portable water drawing device is integrally detachable and foldable, which is convenient for carrying, storage and cleaning. It is convenient to draw water. During the whole process of entering water, drawing water, discharging water, transportation, use, etc., the device basically remains in a vertical state, is not easy to tilt and turn over, and the water contained inside is not easy to pour out.

[0056] The above are only some embodiments of the present application. The protection scope of the present application is not limited to the above embodiments. For those of ordinary skill in the art of this technology, several improvements and retouches without departing from the creative design of the present application should also fall within the protection scope required by the present application.
