Description

Technical Field

[0001] This application relates to the field of evaporator device technology, and more particularly to an adjustable conical evaporator. Background Technology

[0002] Currently, most water purification products on the market use filtration to separate and obtain pure water. Filter membranes are mainly divided into ultrafiltration membranes and RO reverse osmosis membranes. Filter cartridges, with the filter membrane at their core, typically need to be replaced periodically, usually every 3-18 months, depending on the local water quality. This filtration method not only has expensive filter cartridges but also requires external electrical power to operate.

[0003] In traditional solar evaporators, the condensation of steam typically occurs on a transparent plate at the top of the evaporator. This plate, usually made of plastic or glass, causes the steam vapor to condense on its inner surface, reducing its light transmittance and consequently decreasing the evaporation rate and condensation efficiency. Simultaneously, the increased condenser temperature during evaporation hinders the condensation process, further reducing the amount of water collected. Summary of the Invention

[0004] The main objective of this application is to provide an adjustable conical evaporator, which aims to solve the technical problem in the prior art that the condensation of steam generally occurs on the transparent plate at the top of the evaporator, and the water vapor condensed on the transparent plate reduces the light transmittance of the transparent plate, resulting in a decrease in evaporation rate and condensation efficiency.

[0005] To achieve the above objectives, this application provides an adjustable conical evaporator, comprising: A condenser, which has a condensation section; An evaporator having an evaporation section, wherein an evaporation space is formed between the evaporation section and the condensation section; The evaporator has a groove at its upper end, and the area formed by the cross-sectional contour of the groove gradually decreases from top to bottom. The evaporator is provided with a light-transmitting plate that can block the groove, and light can shine into the groove through the light-transmitting plate to heat the evaporation section. The evaporation section is connected to a guide member, which is used to guide the water to be purified to the surface of the evaporation section. The evaporation section can be heated so that the water to be purified on its surface evaporates into the evaporation space. The condensation section is used to condense the water vapor in the evaporation space.

[0006] Optionally, the evaporation section has a first wall located within the evaporation space, the first wall being configured as annular, and the area of ​​the region enclosed by the cross-sectional contour of the first wall gradually decreasing from top to bottom.

[0007] Optionally, the condensation section has a second wall located within the evaporation space, and the distance between the second wall and the first wall is equal everywhere.

[0008] Optionally, the condenser has a receiving cavity, which includes a condensing cavity and a water collecting tank that are interconnected. The space enclosed by the condensing section constitutes the condensing cavity. The evaporating section is at least partially located within the condensing cavity. Water condensed by the condensing section can enter the water collecting tank along the condensing section.

[0009] Optionally, it also includes a water storage tank for holding water to be purified. The water collection tank is provided with a water inlet pipe. The first end of the diverting component is connected to the evaporator, and the second end of the diverting component is immersed in the water to be purified in the water storage tank through the water inlet pipe.

[0010] Optionally, the water collection tank is connected to a water outlet pipe, the water outlet end of the water outlet pipe is located outside the water storage tank, the water inlet pipe is located below the evaporator, and the pipe opening of the water inlet pipe near the evaporator is located above the pipe opening of the water inlet end of the water outlet pipe.

[0011] Optionally, the water storage tank is provided with a rotating shaft assembly, which is used to adjust the relative position of the evaporator. The rotating shaft assembly includes a clamp and rotating shafts. The clamp is used to connect to the outer wall of the condenser. One end of the two rotating shafts is connected to the clamp, and the other end is rotatably connected to the water storage tank.

[0012] Optionally, the clamp includes a first clamp body and a second clamp body, which are fastened together to form a limiting space for holding the condenser, and the inner sidewalls of the first clamp body and the second clamp body are provided with protective pads.

[0013] Optionally, the evaporation section includes a photothermal layer, a conductive layer, and a flow-guiding layer arranged sequentially along the condensation section.

[0015] Optionally, a light-transmitting plate is provided at the upper end of the evaporator.

[0016] Optionally, the upper end of the condenser has an annular first flange, and the upper end of the evaporator has an annular second flange, with a sealing gasket provided between the first flange and the second flange.

[0017] The beneficial effects that this application can achieve are: This application proposes an adjustable conical evaporator. By setting up a condenser and evaporator separated from each other, and connecting a guide to the evaporator, purified water is guided to the surface of the evaporator located within the evaporation space via capillary action. The evaporator is heated, causing the water to be purified adhering to its surface to vaporize. The vaporized water condenses at the condenser and then moves along the inner wall of the condenser for collection. By vaporizing and condensing the water, the purification of the water is achieved. By setting the wall of the evaporator for receiving sunlight on an inclined plane, the area exposed to sunlight is increased, which is more conducive to the heating of the evaporator. The inclusion of a light-transmitting plate ensures that sunlight can reach the evaporator while preventing rainwater from entering the recess and affecting the evaporator's sunlight reception. The recess and the evaporation space are independent, ensuring that water mist does not adhere to the light-transmitting plate during evaporation, thus not affecting the light transmittance of the light-transmitting plate. The evaporator of this application has a simple structure, compact layout, high space utilization, and eliminates the need for frequent replacement of filters, making it economical and environmentally friendly.

[0025] Example 1 Reference Figures 1-6 The first embodiment of this application provides an adjustable conical evaporator 1010, comprising: Condenser 20, which has a condensation section 21; Evaporator 10 has an evaporation section, and an evaporation space 30 is formed between the evaporation section and the condensation section 21; The evaporator 10 has a groove at its upper end. The area formed by the cross-sectional contour of the groove gradually decreases from top to bottom. The evaporator 10 is provided with a light-transmitting plate 90 that can seal the groove. Light can pass through the light-transmitting plate 90 to irradiate the groove and heat the evaporation section. The evaporation section is connected to a guide member 40, which guides the water to be purified to the surface of the evaporation section. The evaporation section can be heated so that the water to be purified on its surface evaporates into the evaporation space 30. The condensation section 21 is used to condense the water vapor in the evaporation space 30.

[0026] In this embodiment, the upper end of the evaporator 10 has a groove, which can be conical. Figure 1 The groove can also be trapezoidal. The evaporator section has a uniform thickness, meaning the thickness remains consistent at all locations. The evaporator 10 has a conical shape, and similarly, its cross-sectional shape can also be trapezoidal, with the lower end being the shorter side of the trapezoid. A light-transmitting plate 90 is positioned at the upper end of the evaporator 10. The light-transmitting plate 90 can be installed on the evaporator 10 by adhesive bonding or by bolting for detachable connection.

[0027] Sunlight can pass through the light-transmitting plate 90 and shine onto the inner wall of the groove, heating the evaporator 10. By designing the groove as a cone or trapezoid and tilting its inner wall, the area of ​​the inner wall receiving sunlight can be increased. Compared to a smaller light-receiving area, under the same conditions, the light-receiving area is larger, resulting in higher heating efficiency for the evaporator 10. The light-transmitting plate 90 is located at the upper end of the evaporator 10, and a sealing ring can be installed between the light-transmitting plate 90 and the evaporator 10 to ensure the airtightness of the space formed between the groove and the light-transmitting plate 90. This prevents water vapor from entering the space enclosed by the groove and the light-transmitting plate 90, thus preventing water vapor from adhering to the inner wall surface of the light-transmitting plate 90 and affecting the light transmittance during sunlight exposure. The light-transmitting plate 90 is located above the evaporator 10. The evaporation and condensation process of the water to be purified occurs within the evaporation space 30. The evaporator 10 separates the light-transmitting plate 90 from the evaporation space 30, ensuring that water vapor in the evaporation space 30 does not enter the groove during the evaporation process. This also ensures that water vapor does not adhere to the inner wall surface of the light-transmitting plate 90 near the groove, effectively ensuring that water vapor does not affect the light transmittance of the light-transmitting plate 90 during the evaporation process of the water to be purified.

[0028] The condenser 20 is located inside the evaporator 10. The upper surface of the condenser 20 is exposed to sunlight, and an evaporation space 30 is formed between the lower surface of the condenser 20 and the upper surface of the evaporator 10. The evaporator 10 can be conical in shape. The guide element 40 can be made of a highly absorbent material, such as cotton cloth or absorbent paper, and guides the water to be purified to the lower surface of the evaporator 10 through capillary action. The upper surface of the evaporator 10 is exposed to sunlight. When the evaporator 10 is heated, the water to be purified on its surface vaporizes. The vaporized water vapor is located within the evaporation space 30, and condenses on the surface of the condenser 20. After condensation, the water vapor moves along the surface of the condenser 20 and is collected. It should be noted that a condensation layer (not shown in the figure) is provided on the outer wall of the condenser 20. This condensation layer is made of a highly absorbent material, such as cotton cloth or absorbent paper. The condensation layer is located within the water to be purified in the water storage tank 50. Through capillary action, the water to be purified in the water storage tank 50 is guided to the surface of the condenser 20, maintaining the condenser 20 at a lower temperature. This improves efficient in-situ latent heat transfer and enhances the steam condensation rate. The evaporator 10 has a ring-shaped structure. The evaporation section can be a part of the evaporator 10. For example, the lower part of the evaporator 10 may be conical, with the evaporation section itself, while the upper part is made of ceramic or similar materials. In this case, only the lower part has a photothermal layer 11, a conductive layer 12, and a flow-guiding layer 13. If the entire evaporator 10 is configured with a three-layer structure consisting of the photothermal layer 11, the conductive layer 12, and the flow-guiding layer 13, then the evaporator 10 is equivalent to the evaporation section.

[0029] Compared to existing solar evaporators 10, where condensation occurs on a transparent plate at the top, resulting in steam mist that condenses on the inner surface of the plate, some of this water vapor blocks sunlight, reducing the plate's light transmittance and consequently decreasing the evaporation rate and condensation efficiency of the water to be purified. Furthermore, the condenser 20 in the traditional evaporator 10 experiences temperature increases during the evaporation process, hindering condensation and further reducing water collection. In this example, the enclosed condenser 20 minimizes heat loss during evaporation, resulting in a higher purified water collection rate.

[0030] Example 2 As an optional implementation, this embodiment provides a specific structure of an evaporation section, including: the evaporation section having a first wall surface located within an evaporation space 30, the first wall surface being configured as annular, and the area of ​​the region enclosed by the cross-sectional contour of the first wall surface gradually decreasing in the direction from top to bottom.

[0031] Specifically, the first wall of the evaporator is also conical in shape, and the taper of the outer wall of the evaporator is consistent with the taper of the groove. Figure 1(As shown in the diagram), the thickness of the evaporation section is uniform at this point. Compared to the case where the thickness of different parts of the evaporation section is inconsistent, the uniform thickness is more conducive to heat conduction, allowing the heat from the photothermal layer 11 to be transferred more evenly to the guiding layer. The inner wall of the groove is the surface of the photothermal layer 11, and the surface of the guiding layer 13 is the first wall surface.

[0032] Optionally, the condenser 21 has a second wall located within the evaporation space 30, and the distance between the second wall and the first wall is equal everywhere.

[0033] Specifically, the condenser 21 is located on the inner wall of the evaporation space 30, which is the second wall surface. The second wall surface is located on the outer periphery of the first wall surface, and the space between the first wall surface and the second wall surface is the evaporation space 30. By limiting the distance between the second wall surface and the first wall surface to be equal everywhere, that is, the second wall surface is also conical, when water vapor is condensed through the second wall surface, the water vapor can move downward along the inner wall of the second wall surface, so as to facilitate the collection of the condensed water.

[0034] Example 3 As an optional implementation, this embodiment provides a specific structure of a condenser 20, including: the condenser 20 has a receiving cavity, which includes a condensing cavity and a water collecting tank 22 that are interconnected; the space enclosed by the condensing section 21 constitutes the condensing cavity; the evaporating section is at least partially located within the condensing cavity; and the water condensed by the condensing section 21 can enter the water collecting tank 22 along the condensing section 21. That is, the projected height of the condensing section 21 in the height direction is the height of the condensing cavity; and the condensing section 21 is arranged in a ring shape, forming the inner edge wall of the condensing cavity.

[0035] Specifically, the condenser 20 can be a thin copper or stainless steel sheet with a thickness of 1-10 mm. The condenser 20 comprises two parts: an upper annular section with a conical shape, and a lower cylindrical section. The upper part is the condenser section 21, and the lower part is the water collection tank 22. Both the outer walls of the condenser section 21 and the water collection tank 22 are provided with the condensation layer described in Embodiment 1 to ensure that the water to be purified in the water storage tank 50 can cool the condenser section 21, maintaining it within a low temperature range. The conical shape of the condenser section 21 allows the condensed water, after condensation of water vapor, to move along its inner wall and enter the water collection tank 22 for collection.

[0036] Optionally, a water storage tank 50 is also included, which is used to hold the water to be purified. A water inlet pipe 60 is provided through the water collection tank 22. The first end of the diverting component 40 is connected to the evaporator 10, and the second end of the diverting component 40 is immersed in the water to be purified in the water storage tank 50 through the water inlet pipe 60.

[0037] Specifically, the water storage tank 50 is used to hold water to be purified. This water can come from artificial injection or naturally collected rainwater. An inlet pipe 60 is installed through the lower end of the water collection tank 22. The inlet pipe 60 is located below the evaporator 10, and a space is formed between the outer wall of the inlet pipe 60 and the inner wall of the water collection tank 22 to hold the condensed water. It should be noted that the upper end of the guide member 40 is the first end, and the lower end is the second end. The second end of the guide member 40 can be located inside the inlet pipe 60, or it can penetrate the inlet pipe 60 and protrude from its lower end. When the condenser 20 is installed inside the water storage tank 50, if the liquid level of the water to be purified in the water storage tank 50 is higher than the lower end of the inlet pipe 60, then the second end of the guide component 40 can be located inside the inlet pipe and extend into the water to be purified. If the water to be purified is located below the condenser 20, then the lower end of the guide component 40 needs to penetrate the inlet pipe 60 and extend into the water to be purified. The length of the guide component 40 can be set according to the actual situation. The liquid level in the water storage tank 50 will not be higher than the upper end of the inlet pipe 60, that is, the water to be purified in the water storage tank 50 will not enter the water collection tank 22 through the inlet pipe 60. The inlet pipe 60 is only for the guide component 40 to guide the water to be purified to the surface of the evaporator 10 through capillary action.

[0038] Optionally, the water collection tank 22 is connected to a water outlet pipe 70, the water outlet end of the water outlet pipe 70 is located outside the water storage tank 50, the water inlet pipe 60 is located below the evaporator 10, and the pipe opening of the water inlet pipe 60 near the evaporator 10 is located above the pipe opening of the water inlet end of the water outlet pipe 70.

[0039] Specifically, by installing a water outlet pipe 70 on the water collection tank 22, the water condensed by the condenser 20 becomes purified water, which is discharged through the water outlet pipe 70. The water outlet pipe 70 can be a flexible hose, and its outlet end is located outside the water storage tank 50. The water inlet pipe 60 is located below the evaporator 10, with its upper end higher than the inlet end of the water outlet pipe 70, ensuring that the purified water in the water collection tank 22 can be discharged through the water outlet pipe 70, rather than being discharged into the water storage tank 50 through the water inlet pipe 60. It should be noted that the water outlet pipe 70 can be a single, integral structure, with its outlet end penetrating through the water storage tank 50. The outlet end of the water outlet pipe 70 can be connected to a collection device for collecting purified water, or a faucet for dispensing water can be installed at the outlet end of the water outlet pipe 70, or a water supply line can be connected to the outlet end of the water outlet pipe 70. The outlet pipe 70 may also include at least three branch pipe structures. The first branch pipe is connected to the water collection tank 22, the third branch pipe passes obliquely through the water storage tank 50, and the second branch pipe connects the first branch pipe and the third branch pipe. The second branch pipe can be a flexible hose. In this case, when the condenser 20 and the evaporator 10 are rotated around the axis of the rotating shaft 81, the third branch pipe will not change, and the second branch pipe can bend or twist adaptively.

[0040] Example 4 Based on Embodiment 2, this embodiment provides a specific structure of a rotating shaft assembly 80, including: a rotating shaft assembly 80 is provided on a water storage tank 50, the rotating shaft assembly 80 is used to adjust the relative position of the evaporator 10, the rotating shaft assembly 80 includes a clamp and rotating shafts 81, the clamp is used to connect with the outer wall of the condenser 20, one end of the two rotating shafts 81 is connected to the clamp, and the other end is rotatably connected to the water storage tank 50.

[0041] Specifically, a rotating shaft 81 is connected to each of the opposite ends of the clamp. The two rotating shafts 81 are coaxially mounted on the water storage tank 50, and the condenser 20 and evaporator 10 are supported by the rotating shafts 81. By setting the clamp and rotating shafts 81, the condenser 20 and evaporator 10 can rotate around the axis of the rotating shafts 81, thereby changing the orientation of the evaporator 10. As an option, the rotating shafts 81 can be connected to a servo motor to drive the rotating shafts 81 to rotate at different times, so that the evaporator 10 can adjust its angle according to the movement of the sun, ensuring that sunlight can reach the evaporator 10 as much as possible. Similarly, a lever 84 can be installed on one of the two rotating shafts 81. The lever 84 can be welded to the rotating shaft 81, or a mounting hole for installing the lever 84 can be provided on the rotating shaft 81. This allows for manual application of a circumferential rotational force to the rotating shaft 81 via the lever 84, thereby adjusting the relative angle of the evaporator 10.

[0042] Optionally, a positioning nut 85 is provided on the rotating shaft 81. The positioning nut 85 is threaded into the rotating shaft 81. When the condenser 20 and evaporator 10 are rotated to a certain angle by the rotating shaft 81, the positioning nut 85 is screwed in to abut against the side wall of the water storage tank 50, thus fixing the condenser 20 and evaporator 10 together. It should be noted that a positioning nut 85 can be provided on each of the two bearings on both sides of the side wall of the water storage tank 50 to improve the stability of the condenser 20 and evaporator 10 after they have been rotated to a certain angle. As another method, for fixing the whole formed by condenser 20 and evaporator 10, a shaft hole for mounting shaft 81 is provided on water tank 50. The shaft 81 and the shaft hole can be an interference fit, that is, rotating shaft 81 requires overcoming a certain external force. After the whole formed by condenser 20 and evaporator 10 is rotated by a certain angle through shaft 81, the external force applied to shaft 81 is removed. The vertical component of the whole formed by condenser 20 and evaporator 10 is less than the external force that needs to be overcome by the interference fit, thus maintaining the structural stability of the whole formed by condenser 20 and evaporator 10.

[0043] Optionally, the clamp includes a first clamp body 82 and a second clamp body 83, which fasten together to form a limiting space for clamping the condenser 20, and the inner sidewalls of the first clamp body 82 and the second clamp body 83 are provided with protective pads 86.

[0044] Specifically, both the first hoop 82 and the second hoop 83 can be semi-circular, with a mounting lug at each end. The two sets of mounting lugs can be connected by bolts. Alternatively, the first ends of the first hoop 82 and the second hoop 83 can be hinged together, and the second ends can be connected by a bolt assembly. The first hoop 82 and the second hoop 83 can also be connected by a snap-fit ​​assembly. The two rotating shafts 81 can be welded to the first hoop 82 and the second hoop 83 respectively. It should be noted that a through hole is provided on the side wall of the water storage tank 50 for the first hoop 82 and the second hoop 83 to pass through. A bearing seat can be installed in the through hole, and a bearing is installed in the bearing seat. The rotating shafts 81 are mounted on the bearing. By setting a protective pad 86, when the clamps are used to tighten the outer wall of the condenser 20, the clamps make flexible contact with the outer wall of the condenser 20, avoiding damage to the outer wall of the condenser 20 by the clamps.

[0045] Example 5 As an optional implementation, this embodiment provides a specific structure of an evaporation section, including: the evaporation section includes a photothermal layer 11, a conductive layer 12 and a flow guiding layer 13 arranged sequentially along the condensation section 21.

[0046] Specifically, the conductive layer 12 can be a copper or stainless steel sheet with a thickness of 1-10 mm; the photothermal layer 11 can be made of manganese dioxide, carbon black, and varnish mixed in a certain proportion; and the drainage layer 13 covers the outer wall of the conductive layer. The drainage layer 13 can be made of a highly absorbent material, such as cotton cloth or absorbent paper. The function of the photothermal layer 11 is to absorb light energy and convert it into heat energy, providing heat for the evaporation process; the function of the conductive layer 12 is to conduct the heat generated by the photothermal layer 11 to the drainage layer 13, causing the liquid in the drainage layer 13 to evaporate; the function of the drainage layer 13 is to adsorb the liquid, allowing the liquid to fully contact the conductive layer 12, thereby absorbing the heat transferred by the conductive layer 12 for evaporation.

[0047] Optionally, the inner diameter of the evaporator 10 gradually decreases from top to bottom.

[0048] Specifically, the evaporator 10 has an inverted cone shape, and its inner diameter gradually decreases from top to bottom. This angles the portion receiving sunlight, increasing the surface area exposed to heat and improving the evaporation efficiency of the water to be purified on the surface of the evaporator 10. The condenser 20 can have the same taper as the evaporator 10. The cone design reduces the volume of the evaporation space 30, which can improve the evaporation and condensation efficiency of water.

[0049] Optionally, a light-transmitting plate 90 is provided at the upper end of the evaporator 10.

[0050] Specifically, the light-transmitting plate 90 is a transparent disc-shaped material, which can be a Fresnel lens, high-transmittance glass, or other high-transmittance acrylic or PC panels. By setting the light-transmitting plate 90, sunlight can reach the evaporator 10 while preventing rainwater from entering and accumulating inside, thus affecting the evaporation of the water to be purified on the evaporator 10's heating and evaporation process. The space between the light-transmitting plate 90 and the evaporator 10 forms a light-illuminating zone, where sunlight irradiates the evaporator 10, thereby heating it. It should be noted that the plane containing the light-transmitting plate 90 can be parallel to the horizontal plane. Figure 1 (As shown in the figure), the plane where the light-transmitting plate 90 is located can also form a certain angle with the horizontal plane (not shown in the figure).

[0051] Optionally, the upper end of the condenser 20 has an annular first flange 101, and the upper end of the evaporator 10 has an annular second flange 102, with a sealing gasket 100 provided between the first flange 101 and the second flange 102.

[0052] Specifically, by setting a sealing gasket 100, the sealing performance between the evaporator 10 and the condenser 20 is improved, forming a relatively sealed space between them, allowing the evaporation process of the water to be purified to occur within this relatively sealed space. The first flange 101 and the second flange 102 can be connected by a bolt assembly, or they can be connected by a snap-fit ​​or sliding mechanism. Through holes coaxial with the first flange 101 and the second flange 102 can also be provided on the light-transmitting plate 90. The first flange 101, the second flange 102, and the light-transmitting plate 90 are then connected by bolt assemblies, enabling the light-transmitting plate 90 to be detachably installed, allowing the evaporator 10 to be disassembled for cleaning according to actual usage. Both the first flange 101 and the second flange 102 are annular. The first flange 101 can be part of the condenser 20 or a structure welded to the condenser 20; the second flange 102 is installed in the same way. When the evaporator 10 includes a conical portion and an annular flange structure, the annular flange structure is the second flange 102, and the conical portion is the evaporation section. It should be noted that the first flange 101 and the second flange 102 can be made of heat-insulating materials, such as asbestos, glass wool, vacuum insulation panels, etc., to reduce the heat exchange between the evaporator 10 and the condenser 20 through the first flange 101 and the second flange 102.

[0053] In this embodiment, the adjustable conical evaporator is adjustable because the evaporator 10 and condenser 20 are rotated around the rotating shaft 81 driven by the rotating shaft assembly 80. Its operating principle is as follows: In use, the water storage tank 50 is placed in a location where it can receive sunlight. The water to be purified is contained in the water storage tank 50, and the water to be purified in the water storage tank 50 is guided to the guide layer of the evaporator 10 by the capillary action of the guide element 40. Sunlight shines on the photothermal layer of the evaporator section through the light-transmitting plate 90, causing the temperature of the photothermal layer to rise. Then, the heat is transferred to the guide layer through the conduction layer, evaporating the water to be purified on the guide layer. The water vapor dissipates in the evaporation space 30 and then condenses on the condenser 20 (the outer wall of the condenser 20 is provided with a condensation layer, and the water in the water storage tank 50 is guided to the condensation layer by capillary action, keeping the condenser 20 at a relatively low temperature). The generated steam will condense on the inner surface of the condenser 20 through the transfer of latent heat, and the latent heat will then be transferred to the atmosphere through convection and radiation. After the water vapor comes into contact with the inner wall of the condenser 20, its temperature decreases, and the water vapor condenses into a liquid state and adheres to the inner wall of the condenser 20. The condensed water is purified water. The purified water moves along the inner wall of the condenser 20 into the water collection tank 22, and then is delivered to the water-using equipment through the outlet end of the water outlet pipe 70. The water-using equipment can be a tap that can be used immediately or a purified water collection tank. The outlet end of the water outlet pipe 70 can also be a water supply line, and then the water is delivered to the place where it is needed through the water supply line.
