Description

Technical Field

[0001] This utility model relates to the field of water purification equipment, specifically to a portable water purification device. Background Technology

[0002] Freshwater resources remain scarce in many countries, and per capita water availability in northern my country, northwestern inland areas, and coastal regions is below the world average. Existing seawater desalination and purification devices or portable water purification devices are generally large in size, inconvenient to move or carry, and have limited application scenarios.

[0003] For example, Chinese patent CN110182873B discloses a portable seawater desalination and purification device, comprising a compressor, a sealed container for holding the compressor, and a sealed evaporation and condensation chamber. A seawater inlet copper pipe is arranged at the bottom of the inner cavity of the sealed evaporation and condensation chamber, connected to a seawater inlet pipe. A concentrated brine drain pipe, connected to the inner cavity, is connected to the bottom of the sealed evaporation and condensation chamber. The sealed container is placed inside the sealed evaporation and condensation chamber, above the seawater inlet copper pipe. A steam inlet, communicating with the inner cavity of the sealed evaporation and condensation chamber, is located at the top of the sealed container. An evaporator heat exchange tube is attached to the outer surface of the sealed container in a circumferential manner. The inlet of the evaporator heat exchange tube is connected to a steam outlet on the sealed container, and the outlet of the evaporator heat exchange tube is connected to a freshwater outlet pipe. A seawater spray head is arranged above the sealed container, connected to the seawater inlet copper pipe via a seawater supply pipe. The aforementioned invention patent has a compact structure and can effectively desalinate seawater. However, it is short of being used because it requires connection to a seawater inlet pipe and requires opening the ventilation valve on top of the device when discharging concentrated brine. This limits its application scenarios and makes it unsuitable for emergency use. Utility Model Content

[0011] The evaporator body includes a first housing and a second housing, with a gap between the first housing and the second housing, and refrigerant pipes passing through the first housing and the second housing respectively.

[0012] The suction device includes a volute and a fan. The fan is located inside the volute, and the volute includes an air intake and a return pipe. The air intake faces the evaporator body.

[0013] The electrical components and wiring harnesses of the heating device, the heat exchange device, and the suction device are all housed in the electrical box.

[0014] It also includes a housing, which is detachably connected to the base.

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0032] This invention provides a portable water purification device, and the preferred embodiments of the portable water purification device are described below.

[0033] Example 1

[0034] Reference Appendix Figure 1The portable water purification device in this embodiment includes a base 100, a heating device 200 on the base 100, an evaporation tank 201 placed on the heating device 200, a water receiving tray 500 on the base 100, the water receiving tray 500 being located above one side of the evaporation tank 201, a heat exchange device 300 on the water receiving tray 500, a suction device 400 on the side of the heat exchange device 300 facing away from the evaporation tank 201, a water outlet pipe 501 on the water receiving tray 500, and a purified water tank 502 located below the outlet of the water outlet pipe 501. The heating device 200 is located at the bottom of the evaporation tank 201, heating the evaporation tank 201 and evaporating the impurities or seawater in the evaporation tank 201 to generate steam. The steam passes through the outlet above the evaporation tank 201, and is condensed into distilled water by the airflow generated by the suction device 400 upon contact with the heat exchange device 300. The distilled water drips into the water receiving tray 500 and is collected in the purified water tank 502.

[0035] The heat exchange device 300 includes an evaporator body 301 and a compressor 302. A refrigerant tube 303 is coiled inside the evaporator body 301. The refrigerant tube 303 includes an inlet pipe 304 and a return pipe 305, which are respectively connected to the compressor 302 to form a circuit. Refrigerant circulates in the refrigerant tube 303 circuit. The coiling of the refrigerant tube 303 increases the contact area between the refrigerant tube 303 and the evaporator body 301, improving refrigeration efficiency. The evaporator body 301 rapidly cools down, absorbing heat and condensing the vapor.

[0036] The evaporator body 301 includes a first housing 307 and a second housing 308, with a gap between the first housing 307 and the second housing 308, and refrigerant pipes 303 passing through the first housing 307 and the second housing 308 respectively. The gap between the first housing 307 and the second housing 308 increases the overall surface area of ​​the evaporator body 301, thereby improving the condensation efficiency of the steam.

[0037] In this embodiment, when the portable water purification device is running, the electric heating device 200 heats the water in the evaporation tank 201 until it evaporates to produce steam. The steam is guided by the airflow of the suction device 400 to contact the evaporator body 301 of the heat exchange device 300. The refrigerant pipe 303 circulates and cools under the drive of the compressor 302, which lowers the temperature of the inner wall of the evaporator body 301. The steam condenses into liquid water upon contact with the condenser, flows into the water receiving pan 500, and then enters the purification water tank 502 through the water outlet pipe 501.

[0038] This utility model is small in size and has high water purification efficiency, and can be used as an emergency device in environments with high air humidity.

[0039] Example 2

[0040] Reference Appendix Figure 2 , 3In embodiment 4, the portable water purification device includes a base 100, which is square in shape, with a caster wheel 111 at each of the four corners of the bottom. A heating device 200 is located on one side of the base 100. The heating device 200 is electrically heated, circular in shape, and embedded in a tray 109, with its top surface flush with the top surface of the heating device 200. An evaporation tank 201 is placed on the heating device 200. The evaporation tank 201 is made of a metal material with high thermal conductivity. The bottom surface of the evaporation tank 201 is in contact with the heating device 200 and is supported by the tray 109. The evaporation tank 201 is a rectangular metal container with a steam outlet on one side of its top surface. The heating device 200 heats the impurity water or seawater in the evaporation tank 201 to generate steam, which is discharged through the steam outlet. Water is also added to the evaporation tank 201 through the steam outlet. A water collection tray 500 is provided on the base 100. The water collection tray 500 is located above one side of the evaporation tank 201, and its bottom surface is inclined to facilitate the centralized collection of condensate. A heat exchange device 300 is provided on the water collection tray 500 to cool the steam discharged from the evaporation tank 201 into distilled water, which drips and is collected in the water collection tray. A suction device 400 is provided on the side of the heat exchange device 300 facing away from the evaporation tank 201 to generate airflow to guide the steam to the heat exchange device 300, thereby improving condensation efficiency. The water collection tray 500 is provided with a water outlet pipe 501. A purified water tank 502 is located below the outlet of the water outlet pipe 501. The condensate in the water collection tray 500 is collected in the purified water tank 502 through the water outlet pipe 501.

[0041] The evaporation tank 201 has a handle that allows it to be pulled off the tray 109 for easy cleaning of the interior of the evaporation tank 201.

[0042] Reference Appendix Figure 2 and 5 The heat exchange device 300 includes an evaporator body 301 and a compressor 302. A refrigerant pipe 303 is coiled inside the evaporator body 301. The refrigerant pipe 303 includes an inlet pipe 304 and a return pipe 305, which are respectively connected to the compressor 302 to form a loop. A filter 310 is installed on the loop of the refrigerant pipe 303 to filter impurities during the refrigerant circulation process; this filter is removable. The refrigerant tubes pass through and are coiled in the evaporator body 301. The inlet pipe 304 and return pipe 305 of the refrigerant tubes are respectively connected to the compressor 302, forming a refrigerant circulation loop. The compressor 302 delivers refrigerant to the refrigerant tubes, and the large-area contact between the refrigerant tubes 303 and the evaporator body 301 cools the evaporator body 301.

[0043] Both the intake pipe 304 and the return pipe are equipped with shock-absorbing bends 306, and the return pipe is equipped with a refrigerant charging pipe 309. The intake pipe 304 and the return pipe 305 extend from the evaporator body 301, bypass the suction device 400, and connect to the compressor 302 located below the suction device 400. The shock-absorbing bends 306 are located on one side of the suction device 400 and are inclined. The refrigerant charging pipe 309 extends from a section above the shock-absorbing bend 306 of the return pipe 305 and is sealed. When refrigerant needs to be added, it is added to the refrigerant pipe 303 circuit through the charging pipe 309.

[0044] Reference Appendix Figure 2 and 7 The suction device 400 includes a volute 401 and a fan 402. The fan 402 is located inside the volute 401, and the volute 401 includes an air intake 403 and an air outlet 404. The air intake 403 faces the evaporator body 301. When the fan 402 operates, it draws in gas from the side of the evaporator body 301, accelerating the discharge of the low-temperature gas after condensation. A partition 107 is provided between the volute 401 and the evaporator body 301 to separate the interior of the volute 401 from the evaporator body 301. An opening is provided on the partition 107 to connect the volute 401 and one side of the evaporator body 301. A connecting plate is provided on the side of the evaporator body 301. The partition plate 107 is connected to the evaporator body 301 through the connecting plates on both sides of the evaporator body 301, so that there is a gap between the partition plate 107 and the evaporator body 301. The steam drawn in by the suction device 400 is condensed into condensate on the surface of the evaporator body 301. Some low-temperature gas enters the interior of the volute 401 through the gap between the partition plate 107 and the evaporator body 301 and is discharged from the outlet 404 of the suction device 400.

[0045] The partition 107 connects to the base 100 below, separating the suction device 400, purification water tank 502, and compressor 302 from the evaporator body 301, water tray 500, evaporation water tank 201, and heating device 200. The purification water tank 502 is equipped with a baffle 110, which separates the evaporation water tank 201 into an independent space. The outlet pipe 501 passes through the baffle 110, connecting this independent space to the water tray 500. The distilled water collected in the water tray 500 flows directly into the purification water tank 502 through the outlet pipe 501. The purification water tank 502 is an evaporator body 301 with several openings and a handle. The purification water tank 502 is placed inside the independent space of the baffle 110 from the outside, with one of the larger openings located below the outlet pipe. This design facilitates the replacement of the purification water tank 502.

[0046] Reference Appendix Figure 2 and 7The evaporator body 301 is connected to a guide shroud 101, which is located above the evaporation tank 201 and is funnel-shaped, with its smaller diameter section connected to the evaporator body 301. A bracket 108 is connected to both sides of the tray 109, and the water receiving tray 500 and the guide shroud 101 are respectively connected to this bracket 108. The guide shroud 101 has a height difference between its side and the top surface of the evaporator body 301. Steam drawn in by the suction device 400 is guided by the guide shroud 101; part of it passes over the upper surface of the evaporator body 301, and the other part passes over the lower surface of the evaporator body 301. The steam contacts the evaporator body 301 to produce distilled water, while the remaining low-temperature gas enters the volute 401 through the gap between the partition 107 and the evaporator body 301 and is then discharged.

[0047] Reference Appendix Figure 5 The electrical components and wiring harnesses of the heating device 200, heat exchange device 300 and suction device 400 are all housed in the electrical box 600 for convenient centralized power supply and protection.

[0048] Reference Appendix Figure 6 The portable water purification device in this embodiment also includes a housing 102, which is detachably connected to the base 100. The portable water purification device is located inside the housing 102. The housing 102 is detachably connected to the base 100 by screws, giving the portable water purification device a certain degree of intrusion prevention capability. During the operation of the portable water purification device, it prevents accidental contact with the heat exchange device 300 or the evaporation tank 201, which could cause frostbite or burns. In addition, the portion of the housing 102 located above the evaporation tank 201 can also improve the steam collection efficiency and prevent steam from escaping. The housing 102 is fitted to the top of the aforementioned support 108 and the top of the partition 107, and the port where the air outlet 106 of the volute 401 is located is fitted to the inner surface of the housing 102.

[0049] The outer casing 102 includes an air inlet panel 103 and an air outlet panel 104. The air inlet panel 103 is close to the evaporator tank 201 and away from the heat exchanger 300, and has an air inlet 105. The air outlet panel 104 is located above the outer casing 102 and has an air outlet 106, which is located above the suction device 400. Both the air inlet 105 and the air outlet 106 are grille-shaped openings. The air inlet 105 is used to introduce outside air and also assists in steam cooling. The port where the air outlet 106 of the volute 401 is located is in contact with the inner surface of the air outlet panel 104. The steam guiding structure is formed by the cooperation of the volute 401, partition 107, guide shroud 101, outer shell 102, air inlet panel 103 and air inlet 105. The steam in the evaporation tank 201 flows upward to the cavity between the air inlet panel 103 and the guide shroud 101. The suction device 400 guides the steam and the air drawn in from the air inlet 105 to the guide shroud 101 and enters the gap between the evaporator body 301 and the outer shell 102 and the gap between the evaporator body 301 and the water receiving tray 500 respectively. The steam contacts the surface of the evaporator body 301 to form distilled water. The remaining low-temperature gas enters the suction device 400 and is discharged through the air outlet 404 of the volute 401 and the air outlet 106 of the air outlet panel 104.

[0050] The outer casing 102 also has grille-shaped openings on both sides connected to the air inlet panel 103 to improve air intake efficiency. At the same time, a handle structure is provided on each of these two sides, which, together with the casters 111 on the base 100, facilitates the movement of the water purification structure.

[0051] In this embodiment, when the portable water purification device is in operation, the heating device 200 heats the water in the evaporation tank 201 and generates steam. The suction device operates to draw the steam and the air entering through the air inlet 105 into the guide hood 101 through the steam guide structure. After passing through the guide hood 101, the steam is concentrated around the evaporator body 301. The steam is cooled into distilled water on the surface of the evaporator body 301 and drips into the water receiving tray 500 below the evaporator body 301. The water is collected in the purification tank 502 through the water outlet pipe 501. The cooled low-temperature gas is discharged through the air outlet 404 of the suction device 400.

[0052] The portable water purification device in this embodiment can be used in areas or scenarios where freshwater resources are scarce, such as islands, deserts, coastal areas, cruise ships, or remote areas. It can efficiently produce distilled water from impure water, seawater, and other non-potable water in a convenient way, which can be used for the purification of daily drinking water. In islands and coastal areas with high air humidity, water in the air can be condensed directly through the heat exchange device 300 without the need for a water tank and heating device 200.

[0053] Example 3

[0054] This embodiment further defines the structure of the evaporator body 301. (See attached diagram.) Figure 7 The evaporator body 301 includes a first housing 307 and a second housing 308, with a gap between the first housing 307 and the second housing 308, and the refrigerant pipe 303 passes through the first housing 307 and the second housing 308 respectively.

[0055] Referring to the steam guiding structure in Embodiment 2, when the steam mixture flows through the upper and lower surfaces of the evaporator body 301, some steam enters the gap between the first housing 307 and the second housing 308, which increases the contact area between the steam mixture and the evaporator body 301, resulting in higher steam condensation efficiency.

[0056] This invention features a simple and compact structure with high water purification efficiency, making it suitable for regions or scenarios where freshwater resources are scarce. Its compact design also allows for easy portability and mobility, enhancing its flexibility and providing emergency preparedness.

[0057] The above description is a preferred embodiment of the present utility model, used to illustrate the present utility model and its effects. It should be noted that, for those skilled in the art, for the purpose of making foreseeable improvements and modifications without departing from the principles of the present utility model, such improvements and modifications are also within the protection scope of the present utility model.
