Description

Technical Field

[0001] The present invention relates to the technical field of dew collecting devices, in particular to a foldable dew collecting device for outdoor survival. Background Art

[0002] Outdoor survival (outdoor survival, wilderness survival) is a practical activity that relies on limited resources or skills to complete survival challenges in a natural environment. It can not only exercise personal abilities, but also cultivate teamwork and emergency response capabilities.

[0003] In outdoor survival activities, water is the most critical resource for maintaining life, and its importance even exceeds that of food. Scientific research shows that humans can survive for three weeks without food, but only three days without water. Water shortage can lead to dehydration, organ failure and even death. When surviving in the wild or in a water-scarce environment, dew is an important source of water, especially in arid areas such as the Gobi and deserts, or in isolated areas where surface water cannot be found. Collecting dew can alleviate short-term water shortages and increase the probability of survival. When the environment permits (humidity, temperature difference) and other water sources are inaccessible or high-risk, collecting dew is a safe, high-efficiency, and low-energy water-collecting option.

[0004] After searching, the Chinese invention patent with publication number CN112878427B discloses a dew collection device, including a liquid collecting body, a filter cover and a liquid collector: the liquid collecting body has an upper end and a lower end, wherein the cross-sectional diameter from the upper end of the liquid collecting body to the middle of the liquid collecting body gradually increases, and the cross-sectional diameter from the middle of the liquid collecting body to the lower end of the liquid collecting body gradually decreases, thereby expanding the contact area with the air and preventing water from accumulating on the inner wall and being unable to flow to the water bag. The outer wall of the liquid collecting body is provided with a plurality of liquid guide grooves extending from the upper end and the lower end, wherein each of the liquid guide grooves of the liquid collecting body is provided with a water leakage hole. This application absorbs water vapor in the air through a hydrophilic skin to achieve the purpose of collecting dew, but for outdoor activities, the hanging placement and exposed design of the device are not conducive to portability, and therefore it is difficult to bring convenience to outdoor water collection.

DETAILED DESCRIPTION

[0029] The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the present invention description are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0030] Example 1

[0031] Refer to the attached Figure 1 The present application provides a foldable dew collection device for outdoor survival, comprising a base 1 for storing water and a capture net 4 for collecting water. The base 1 is provided with a storage mechanism, which comprises a sleeve 2, a frame 5, a fixed block 7, and a central axis 8. The central axis 8 is provided with a movable sleeve 6 on its outer sleeve, and the frame 5 is provided on the movable sleeve 6 and the fixed block 7. The sleeve 2 is rotatably connected to a plurality of shells 3, and the capture net 4 is provided on the shells 3 and the frame 5. The movable sleeve 6 folds the frame 5 by moving on the central axis 8 to store the capture net 4. The shell 3 is used to protect the capture net 4 and divert dew. A window is provided on the base 1, and a transparent cover with a scale on the surface is fixedly connected to the base 1 at the window. When in use, the amount of water collected can be intuitively understood through the scale on the transparent cover.

[0032] Preferably, the capture net 4 is a flexible polyethylene net, which has fast thermal conductivity and a faster dew collection rate. The mesh of the capture net 4 is diamond-shaped, and the condensed dew can flow downward quickly. A filter layer for filtering dew is provided in the base 1. The filter layer includes three parts from top to bottom: a high-precision hollow fiber ultrafiltration membrane, silver-loaded activated carbon and ion exchange resin, to filter and sterilize the collected dew, thereby ensuring outdoor drinking water safety. The outer shell 3 is in the shape of a quarter of a circle, and its inner side is coated with a hydrophobic coating to ensure that the dew formed on the capture net 4 can flow down quickly after dripping onto the outer shell 3, without forming water marks or being retained and gathered into water droplets. The sleeve 2 is threadedly connected to the top of the base 1.

[0033] The capture net 4 can be unfolded in all directions, and the unfolded capture net 4 not only has a larger surface area for collecting dew, but also allows wind speed conditions in each direction to benefit from dew collection, thereby further improving the dew collection rate.

[0034] When the device is in use, the outer shell 3 can be opened after standing on the ground, and then the frame 5 can be driven to open by moving the movable sleeve 6 to unfold the capture net 4. The capture net 4 can be used to capture water vapor to condense into dew, and after condensation, it falls on the inner side of the outer shell 3 under the action of gravity and finally flows into the sleeve 2. After that, the filter layer can be used to filter the water body, and the clean water body is gathered in the base 1, thereby completing the collection and filtration of dew, so as to facilitate water collection and use in outdoor activities.

[0035] Refer to the attached Figure 2 The skeleton 5 includes a first link 501, a second link 502, a third link 503, a fourth link 504, a fifth link 505 and a sixth link 506. One end of the first link 501 is rotatably connected to the movable sleeve 6, one end of the sixth link 506 is rotatably connected to the fixed block 7, the other end of the sixth link 506 is rotatably connected to the rod body of the first link 501, the fourth link 504 is rotatably connected to the other end of the first link 501, the fifth link 505 is rotatably connected between one end of the fourth link 504 and the rod body of the sixth link 506, the other end of the fourth link 504 is rotatably connected to the rod body of the third link 503, the second link 502 is rotatably connected between one end of the third link 503 and the rod body of the first link 501, and the capture net 4 is fixedly connected between the first link 501, the third link 503 and the shell 3.

[0036] The structure of the assembly for storing the capture net 4, which is composed of a skeleton 5 consisting of six connecting rods, a movable sleeve 6, and a central axis 8, is the same as the principle of an existing folding umbrella. It is conventional technical content and will not be repeated here.

[0037] Example 2

[0038] Refer to the attached Figure 3-5 The present application provides a foldable dew collection device for outdoor survival. Compared with Example 1, in order to facilitate the filtering of collected dew, a plurality of grooves are equidistantly provided at the bottom end of the base 1. The base 1 is provided with a threaded rod 102 in the groove. One end of the threaded rod 102 is fixedly connected to a pad 103, and the other end of the threaded rod 102 is externally threadedly connected to a threaded sleeve 101. The threaded sleeve 101 is rotatably connected to the base 1 at the inner wall of the groove through a damping shaft.

[0039] When the device is placed for use, the threaded sleeve 101 can be pulled to deflect downward. After all the threaded sleeves 101 are pulled out, the pad 103 can be twisted to rotate. The pad 103 drives the threaded rod 102 to rotate, and the total length of the threaded sleeve 101 and the threaded rod 102 can be adjusted. The height and position of the pad 103 are adjusted to ensure the verticality of the device when it is placed on uneven ground outdoors, so as to maintain the stability of the device when it is placed for use.

[0040] Preferably, a bearing 10 is fixedly connected to the top end of the inner part of the base 1, and a drum 9 is fixedly connected to the inner side of the bearing 10. The bearing 10 includes an inner ring, an outer ring and several steel balls therebetween. The inner ring is fixedly connected to the drum 9, and the outer ring is fixedly connected to the base 1, so as to ensure that the drum 9 can be made and driven to rotate. Several water filter ports are equidistantly provided on the outside of the drum 9. The drum 9 is fixedly connected to a filter screen 11 at the water filter port. A water inlet is provided at the top of the drum 9. A funnel 201 is fixedly connected to the inner side of the sleeve 2. The bottom end of the funnel 201 extends into the drum 9 at the water inlet. The diameter of the water inlet is larger than the diameter of the narrow mouth of the funnel 201. In this case, the drum 9 will not contact the funnel 201 when rotating, so as to avoid the possibility of the sleeve 2 loosening. A net box 18 is fixedly connected to the inside of the base 1 below the drum 9, and the filter layer is arranged in the net box 18.

[0041] When the outer shell 3 guides the dew into the sleeve 2, the funnel 201 can collect the water and introduce it into the drum 9. In this case, the motor in the housing 13 is started to drive the bevel gear 16 to rotate. The bevel gear 16 can drive the drum 9 to rotate through the bevel gear ring 17. Therefore, the drum 9 can generate centrifugal force through its own rotation and actively filter the water through the filter 11 to ensure the cleanliness of the collected dew.

[0042] Preferably, a motor is fixedly connected to the inner wall of one side of the base 1, a power supply electrically connected to the motor is provided inside the base 1, the inner wall of the base 1 is fixedly connected to the organic shell 13 at the outside of the motor, one end of the output shaft of the motor is connected to a bevel gear 16 through a key, the bottom end of the drum 9 is fixedly connected to the rotating drum, and the rotating outside is connected to a bevel gear ring 17 through a key, and the bevel gear 16 is engaged with the bevel gear ring 17.

[0043] Preferably, the inner wall of the base 1 is provided with several pressure-touch components on the outer side of the drum 9, and the pressure-touch components include two side plates 19, both of which are fixedly connected to the inner wall of the base 1, and a stainless steel roller 20 is rotatably connected between the two side plates 19, so that the strength of the pressure-touch component can be ensured, and the outer sleeve of the roller 20 is provided with a rubber sheath 21, so that mechanical damage between the roller 20 and the spring sheet 12 can be avoided, and the roller 20 can also convert the friction between it and the spring sheet 12 into its own rotation, so as to further avoid wear between parts, and several spring sheets 12 are equidistantly fixedly connected to the outer side of the drum 9, and the spring sheets 12 are inclined, and the height of the spring sheets 12 is the same as the height of the roller 20.

[0044] Since the rotation of the drum 9 can drive the spring sheet 12 to rotate, and the roller 20 can squeeze it during its rotation, the spring sheet 12 will deform and accumulate energy when it contacts the roller 20. When the spring sheet 12 continues to move until it separates from the roller 20, the spring sheet 12 can vibrate due to its own elastic force.

[0045] Preferably, a pendulum rod 14 is fixedly connected to the outside of the output shaft of the motor, and a pendulum 15 is fixedly connected to one end of the pendulum rod 14. The pendulum rod 14 and the pendulum 15 are both made of rubber material. The length of the pendulum rod 14 is equal to the distance between the output shaft of the motor and the rotating drum 9. Therefore, when the pendulum rod 14 swings the pendulum 15, it is certain that it can contact the rotating drum 9 and ensure the generation of vibration by hitting it.

[0046] In addition, when the motor drives the bevel gear 16, the pendulum 15 is also driven to rotate through the pendulum rod 14, so the pendulum 15 can be used to continuously hit the drum 9. At the same time, the shaking of the spring sheet 12 can cause the drum 9 to vibrate. The use of this vibration can not only improve the filtering effect of the water body, but also prevent the filter from being blocked, thereby maintaining the water filtering efficiency.

[0047] Example 3

[0048] Refer to the attached Figure 6 The present application provides a foldable dew collection device for outdoor survival. In order to facilitate the carrying of the device and the convenience of collecting dew, it also includes an outer tube 22 mounted on the outside of the base 1, and an inner bag 23 is provided inside the outer tube 22. The tube mouth of the outer tube 22 is fixedly connected to the bag mouth of the inner bag 23, and the inner bag 23 is made of food-grade TPU. A cloth pull ring 24 is fixedly connected to the inside of the inner bag 23. The outer tube 22 is provided with a tube cover 26 at the tube mouth, and the tube cover 26 is fixedly connected to the outer tube 22 by a zipper.

[0049] When carrying the device, the inner bag 23 can be pushed into the outer tube 22, then put on the outside of the device, and the zipper can be pulled to close the outer tube 22. At this time, the outer tube 22 and the inner bag 23 can protect the device to ensure safety when carrying it outdoors.

[0050] Since the space for accommodating the device formed by the outer tube 22 and the inner bag 23 is not connected to the water storage space, the cleanliness of the collected dew can be guaranteed and it can be prevented from being contaminated.

[0051] Preferably, a water outlet is provided at one side of the top end of the outer cylinder 22 and at the bottom end of the base 1. The top end of the outer cylinder 22 is fixedly connected to a material pipe 25 at the water outlet. Sealing plugs are provided on the material pipe 25 and on the base 1 at the water outlet. Connecting ropes are fixedly connected between the outer cylinder 22 and the base 1 and the two sealing plugs respectively.

[0052] When the device is unfolded to collect dew, the inner bag 23 can be pulled outward to the outside of the outer tube 22 through the pull ring 24, and then the material tube 25 can be connected to the water outlet on the base 1 after removing the sealing plug. The outer tube 22 and the inner bag 23 can then be used to store the collected dew, thereby ensuring convenient water storage.

[0053] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention.
