Of course, they are only examples and are not intended to limit the present invention.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0033] An electric water heater uses electric energy as the main energy material. After being powered on, the high-temperature heat generated directly heats the water stored in the electric water heater to achieve the purpose of preparing hot water.

[0034] An electric water heater generally includes components such as a water tank, an electric heating component, and a circuit board. Among them, a water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank, and the circuit board is used to control the on / off operation of the electric heating component so that the water in the water tank is heated to a set temperature.

[0035] For the water tank of an electric water heater, the water tank generally includes a shell and an inner tank, and a heat insulation layer is formed between the shell and the inner tank. Among them, the shell is generally made of plastic material to meet the design requirements of diverse and beautiful shapes; the inner tank can be a metal tank or a plastic tank according to needs.

[0036] In addition, for the heat insulation layer formed between the shell and the inner tank, common heat insulation materials include: asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good heat insulation effect, the heat insulation layer is usually formed by foaming.

[0037] Among them, for the inner tank with a metal tank body, due to the influence of water quality, corrosion is likely to occur inside the inner tank. Therefore, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.

[0038] Since magnesium is the metal with the lowest potential in the electrochemical series and is non-toxic physiologically. Therefore, it is very ideal to use it to make the magnesium rod to protect the inner tank. The size of the magnesium rod is directly related to the length of the time to protect the inner tank and the size of the protection effect. The larger the magnesium rod, the better the protection effect and the longer the protection time.

[0039] And an inlet pipe and an outlet pipe are also configured on the water tank. The inlet pipe is used to transport cold water into the water storage cavity formed in the water tank, and the hot water in the water storage cavity is output from the outlet pipe.

[0040] For an electric heating component, an electric heating method such as an electric heating wire, magnetic energy, or silicon tube heating can be adopted to heat the water stored in the water storage cavity.

[0041] For the circuit board, it is used to receive detection signals sent by relevant sensors (such as a water temperature sensor and a flow sensor), and at the same time, control the on / off operation of the electric heating component.

[0042] When the electric water heater is working, the circuit board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the circuit board controls the electric heating component to be powered off.

[0043] Example 1, refer to Figures 17 - 22 As shown, an embodiment of the present application provides an electrical installation room assembly 120, including: An end cover 121, the end cover 121 is provided with a concave structure, a slot 1211 is provided in the concave structure, and the end cover 121 is further provided with a plugging channel 1212; An inspection cover 122, the inspection cover 122 is arranged on the end cover 121 and covers the concave structure, and an electrical installation room is formed between the inspection cover 122 and the end cover 121; A circuit board 123, the circuit board 123 is located in the electrical installation room and is inserted into the slot 1211; A fixed mounting member 124, the fixed mounting member 124 has a plugging portion 1241 and a limiting portion 1242, the plugging portion 1241 is inserted into the plugging channel 1212 of the end cover 121, and the limiting portion 1242 abuts against the edge of the circuit board 123.

[0044] Specifically, an electrical room assembly 120 is configured in the electric water heater to place the circuit board 123. During the installation process of the circuit board 123, the circuit board 123 is first inserted into the slot 1211 provided on the end cover 121, and the circuit board 123 can be pre-assembled and positioned through the slot 1211.

[0045] Then, the plugging portion 1241 of the fixed mounting member 124 is inserted into the plugging channel 1212 of the end cover 121, so that the fixed mounting member 124 is fixedly mounted on the end cover 121 through the plugging portion 1241. At the same time, the limiting portion 1242 of the fixed mounting member 124 will block and abut against the outside of the circuit board 123 to limit the circuit board 123 from disengaging from the slot 1211.

[0046] By providing a slot 1211 on the end cap 121, the slot 1211 can meet the requirements for the insertion and positioning of the circuit board 123, and the insertion channel 1212 provided on the end cap 121 can be used to connect with the fixed mounting member 124. After the insertion portion 1241 of the fixed mounting member 124 is inserted into the insertion channel 1212, the limiting portion 1242 of the fixed mounting member 124 will abut against the edge of the circuit board 123 to prevent the circuit board 123 from disengaging from the slot 1211, thereby realizing a screwless design of the circuit board 123, reducing the assembly difficulty of the electric water heater and improving the assembly efficiency.

[0047] In one embodiment, a locking portion 1213 is further provided on the end cap 121, and a locking cooperation portion 1243 is provided at the end of the insertion portion 1241. After the insertion portion 1241 is inserted into the insertion channel 1212, the locking portion 1213 is connected to the locking cooperation portion 1243.

[0048] Specifically, in order to improve the installation reliability of the fixed mounting member 124, for the insertion portion 1241, after the insertion portion 1241 is inserted into the insertion channel 1212, the locking cooperation portion 1243 will also pass through the insertion channel 1212 and cooperate with the locking portion 1213 to lock the fixed mounting member 124, so that the insertion portion 1241 of the fixed mounting member 124 will not disengage from the insertion channel 1212, thereby improving the connection reliability.

[0049] Among them, for the physical entities of the locking portion 1213 and the locking cooperation portion 1243, there can be various forms. For example, both the locking portion 1213 and the locking cooperation portion 1243 are protruding tooth structures, and the two can be engaged together to achieve a locking effect.

[0050] In another embodiment, a positioning groove 1244 is provided on the limiting portion 1242, and the edge of the circuit board 123 is stuck in the positioning groove 1244.

[0051] Specifically, in order to improve the limiting reliability of the limiting portion 1242 for the circuit board 123, a positioning groove 1244 is provided on the limiting portion 1242. After the fixed mounting member 124 is inserted into the insertion channel 1212 through the insertion portion 1241, the limiting portion 1242 will abut against the circuit board 123, and the circuit board 123 will be stuck in the positioning groove 1244.

[0052] In some embodiments, for the slot 1211, in order to improve the insertion reliability of the circuit board 123, the slot 1211 includes two relatively arranged first slot bodies, and the circuit board 123 is inserted between the two first slot bodies.

[0053] Specifically, during assembly, both side edges of the circuit board 123 are inserted into the corresponding first slots, and the circuit board 123 can be effectively positioned by the first slots on both sides. In addition, the slot 1211 further includes a second slot, which is distributed between the two first slots and is arranged opposite to the limiting portion 1242, and the circuit board 123 is also inserted into the second slot.

[0054] After the circuit board 123 is inserted into the first slot and assembled in place, the corresponding edges of the circuit board 123 will also be located in the slot. In this way, in cooperation with the limiting portion 1242, the four edges of the circuit board 123 are effectively positioned.

[0055] In another embodiment, positioning ribs 1214 may also be provided on the side wall of the recessed structure, and the positioning ribs 1214 abut against the circuit board 123.

[0056] Specifically, the positioning ribs 1214 can abut against the surface of the circuit board 123. The positioning ribs 1214 and the positioning grooves 1244 can play a further limiting role on the circuit board 123. The circuit board 123 is located in the area between the positioning ribs 1214 and the positioning grooves 1244, reducing the shaking of the circuit board 123.

[0057] Embodiment 2, referring to Figures 1 - 8 As shown, an embodiment of the present application provides an electric water heater, including: A housing 100; An inner tank 200, on which a water inlet pipe 210 and a water outlet pipe 220 are provided; A cover assembly 400, which includes an electric shock prevention wall cover 410 and a cover plate 420. A first installation opening 411 is provided on the electric shock prevention wall cover 410, and at least an installation hole 421 is provided on the cover plate 420. The cover plate 420 is detachably arranged in the first installation opening 411; Wherein, the inner tank 200 is arranged in the housing 100, the electric shock prevention wall cover 410 is arranged on the housing 100, the water inlet pipe 210 and the water outlet pipe 220 extend to the outside of the housing 100, and the water inlet pipe 210 and the water outlet pipe 220 are respectively inserted into the installation hole 421.

[0058] Specifically, during the actual assembly process, the inner tank 200 will be first assembled into the housing 100, and a heat insulation layer will be formed by foaming between the inner tank 200 and the housing 100. Then, the electric shock prevention wall cover 410 in the cover assembly 400 is snap-fitted onto the housing 100.

[0059] During the card - mounting process, the water inlet pipe 210 and the water outlet pipe 220 will be inserted into the relatively large - sized first mounting opening 411 formed by the anti - electric - shock wall cover 410. Since the relative movement distance of the water inlet pipe 210 and the water outlet pipe 220 in the first mounting opening 411 is relatively large, in this way, when assembling the anti - electric - shock wall cover 410, the position of the anti - electric - shock wall cover 410 can be adjusted as needed to facilitate reliable assembly onto the housing 100, thereby avoiding the increase in assembly difficulty caused by the interference between the water inlet pipe 210 and the water outlet pipe 220 and the anti - electric - shock wall cover 410.

[0060] After completing the assembly operation of the anti - electric - shock wall cover 410, the cover plate 420 is then assembled onto the anti - electric - shock wall cover 410 to cover the first mounting opening 411, and the water inlet pipe 210 and the water outlet pipe 220 pass through the corresponding mounting holes 421.

[0061] By providing a first mounting opening 411 on the anti - electric - shock wall cover 410 and a detachable cover plate 420 in the first mounting opening 411, during the actual assembly process, when assembling the anti - electric - shock wall cover 410 onto the housing 100, the cover plate 420 is first detached from the anti - electric - shock wall cover 410. In this way, the water inlet and outlet pipes 220 can first be inserted into the first mounting opening 411, and the opening size of the first mounting opening 411 can be large enough to meet the displacement requirements during the assembly of the anti - electric - shock wall cover 410. After the anti - electric - shock wall cover 410 is assembled in place, the cover plate 420 is then assembled onto the anti - electric - shock wall cover 410 to meet the covering requirements around the water inlet and outlet pipes 220, achieving the reduction of the assembly difficulty of the electric water heater and improving the assembly quality.

[0062] In an embodiment of the present application, the first mounting opening 411 is of a strip - shaped structure and extends along the length direction of the housing 100. At least two mounting holes 421 are provided on the cover plate 420. The water inlet pipe 210 is inserted into one of the mounting holes 421, and the water outlet pipe 220 is inserted into the other mounting hole 421.

[0063] Specifically, for the cover plate 420, at least two mounting holes 421 are provided, and thus the installation requirements of the water inlet pipe 210 and the water outlet pipe 220 are respectively met through the mounting holes 421. Regarding the structural shape of the first mounting opening 411, in order to increase the adjustment range of the anti - electric - shock wall cover 410, the first mounting opening 411 is of a strip - shaped structure and extends along the length direction of the housing 100. In this way, when the anti - electric - shock wall cover 410 is card - mounted, it can be card - mounted onto the housing 100 from one side along the length direction of the housing 100. And since the length of the first mounting opening 411 is relatively long, it can also meet the requirement that there is no interference between the anti - electric - shock wall cover 410 and the water inlet pipe 210 or the water outlet pipe 220 during the card - mounting process.

[0064] In some embodiments, there can be various structural forms for the specific assembly method of the shielding cover 420. For example: The shielding cover 420 is fixedly connected to the electric shock protection wall cover 410 by screws, or the shielding cover 420 is snap-fitted onto the electric shock protection wall cover 410.

[0065] In another embodiment, the electric shock protection wall cover 410 has a front panel 412, side panels 413, and a bottom panel 414. The front panel 412 is disposed at the front edge of the bottom panel 414, the side panels 413 are disposed at the corresponding side portions of the front panel 412 and the bottom panel 414, the first mounting opening 411 is provided on the bottom panel 414, the front panel 412 is snap-fitted onto the housing 100, and the edge of the side panel 413 that fits with the housing 100 matches the outer contour of the housing 100.

[0066] Specifically, for the electric shock protection wall cover 410, it is snap-fitted onto the housing 100 through the front panel 412. Among them, an insertion hole 110 is provided on the housing 100, the insertion hole 110 is a strip-shaped hole, and the width of one end of the insertion hole 110 is smaller than that of the other end; a tongue 415 is provided on the front panel 412, and the tongue 415 is inserted into the insertion hole 110.

[0067] The insertion hole 110 extends along the length direction of the housing 100. During assembly, the tongue 415 is inserted into the end with a larger width of the insertion hole 110, and then the electric shock protection wall cover 410 is pushed so that the tongue 415 is stuck on the end with a smaller width of the insertion hole 110 to complete the assembly.

[0068] In order to improve the reliability of the snap-fit, tongues 415 can also be additionally configured on the side panels 413 to assist the front panel 412 in snap-fitting connection through the side panels 413 to improve the reliability of the assembly.

[0069] In an embodiment of the present application, a second mounting opening 416 is provided on the front panel 412, and a detachable control panel 430 is provided in the second mounting opening 416.

[0070] Specifically, the second mounting opening 416 provided on the front panel 412 is used to mount the control panel 430, and the control panel 430 is mounted in the second mounting opening 416 by means of snap-fit screw connection or the like.

[0071] In another embodiment of the present application, a hidden cover 440 is further included. The hidden cover 440 is detachably disposed at the bottom of the electric shock protection wall cover 410 and covers the water inlet pipe 210 and the water outlet pipe 220.

[0072] Specifically, in order to optimize the overall appearance effect, a hidden cover 440 can be provided on the electric shock protection cover 410. The hidden cover 440 can block the parts of the water inlet pipe 210 and the water outlet pipe 220 that extend outside the electric shock protection cover 410, thereby optimizing the overall appearance effect of the water heater.

[0073] In an embodiment of the present application, the inner tank 200 includes an upper tank body 230 and a lower tank body 240. The upper tank body 230 is disposed above the lower tank body 240. The water inlet pipe 210 extends into the lower tank body 240, and the water outlet pipe 220 extends into the upper tank body 230.

[0074] Specifically, in order to increase the water storage capacity, the inner tank 200 includes an upper tank body 230 and a lower tank body 240 arranged up and down. The upper tank body 230 and the lower tank body 240 are disposed in the outer shell 100. Moreover, electric heating devices 300 are arranged in the upper tank body 230 and the lower tank body 240 to meet the requirements of water heating.

[0075] Among them, in order to enrich the heating mode and improve the user experience, a first electric heating tube 310 is arranged in the lower tank body 240, and the first electric heating tube 310 extends and is arranged at the bottom of the lower tank body 240; a second electric heating tube 320 and a third heating tube 330 are arranged in the upper tank body 230. The second electric heating tube 320 extends and is arranged at the bottom of the upper tank body 230, and the third heating tube 330 extends to the upper pipe orifice of the water outlet pipe 220.

[0076] Specifically, there are 2 heating tubes in the upper tank body 230. The third heating tube 330 is close to the water outlet of the water outlet pipe 220, and the second electric heating tube 320 is located on the lower side of the upper tank body 230. When the user uses hot water, the third heating tube 330 close to the water outlet starts to heat, quickly discharging hot water. When a large amount of water is needed, the second heating tube on the lower side of the upper tank body 230 starts to heat. The lower tank body 240 is configured with a first heating tube close to the bottom of the tank to achieve the purpose of increasing the hot water capacity.

[0077] In an embodiment of the present application, an insertion port 130 is provided on the end cover 121; the electric water heater further includes a magnesium rod 250. A cap 260 is provided at the end of the magnesium rod 250, and the cap 260 is clamped in the insertion port 130.

[0078] Specifically, in order to reduce the formation of scale in the inner tank 200, a magnesium rod 250 is usually arranged in the inner tank 200 for water quality treatment, and the magnesium rod 250 needs to be replaced and maintained regularly. For this purpose, in order to meet the requirements for the disassembly and assembly of the magnesium rod 250, an insertion port 130 is provided on the end cover 121 to meet the installation requirements of the magnesium rod 250. The magnesium rod 250 passes through the insertion port 130 and is fixedly connected to the inner tank 200. Moreover, a cap 260 is provided at the end of the magnesium rod 250, and the insertion port 130 is covered by the cap 260 to reduce the leakage of heat in the inner tank 200 to the outside through the magnesium rod 250, so as to improve the heat preservation performance.

[0079] Among them, a handle can be provided on the cap 260. The cap 260 is sleeved on the nut configured for the connection between the magnesium rod 250 and the inner tank 200. By rotating the cap 260 through the handle, the nut can be driven to rotate, so that the operator can disassemble and assemble the magnesium rod 250 without the aid of other tools.

[0080] Embodiment 2: In some embodiments, in order to improve the water quality of the water entering the inner tank and reduce the scale generated in the inner tank, a filter 500 can also be provided on the water inlet pipe, and the hidden cover 440 also covers the filter 500.

[0081] Specifically, in order to optimize the water quality entering the inner tank, the water entering the inner tank through the water inlet pipe can be first filtered through the filter to improve the water quality of the water entering the inner tank. At the same time, for the filter, since it is hidden behind the hidden cover, the aesthetic requirements of the overall appearance of the water heater can be met.

[0082] In another embodiment of the present application, for the filter, in order to extend its service life, the following structural improvements can also be made to the filter.

[0083] As Figures 9 - 14 shown, generally, the filter includes an installation main body 1 and a filtering component. The filtering component includes a filter element 2 and a filter bottle 3. The installation main body 1 is used to meet the connection requirements between the water inlet pipe of the water heater and the water supply pipe in the user's home. At the same time, the installation main body 1 is also used to install the filter element 2 and the filter bottle 3 of the filtering component.

[0084] The filter bottle 3 and the filter element 2 are arranged on the installation main body 1. The filter bottle 3 covers the filter element 2. The water inlet connecting pipe 11 is communicated with the inlet, and the water outlet connecting pipe 12 is communicated with the outlet. Among them, a water inlet connecting pipe 11 and a water outlet connecting pipe 12 are provided on the installation main body 1; the filter element 2 includes a shell 21 and a filter net 24. The shell 21 is provided with an inlet and an outlet, and the filter net 24 covers the inlet.

[0085] In addition, since the filter element 2 is installed between the installation main body 1 and the filter bottle 3, in order to meet the requirement of regularly cleaning the filter screen 24 on the filter element 2, the filter further includes a cleaning component 6, and the cleaning component 6 is provided with a first water flow driving part 61 and a first cleaning part 62.

[0086] The cleaning component 6 is rotatably sleeved on the housing 21, the first water flow driving part 61 is configured to be driven by water flow to drive the cleaning component 6 to rotate on the housing 21, and the first cleaning part 62 is configured to rotate along with the cleaning component 6 to scrape the filter screen 24 on the housing 21.

[0087] Correspondingly, in order to discharge the sewage formed by cleaning in time after the filter element 2 is cleaned by the cleaning component 6, a sewage discharge connecting pipe 17 is further arranged on the installation main body 1, and the sewage discharge connecting pipe 17 is communicated with the inner space of the filter bottle 3.

[0088] Specifically, during actual use, when the filter is in normal filtering use, water enters the installation main body 1 through the water inlet connecting pipe 11 and flows into the filter bottle 3. The water is filtered by the filter screen on the housing 21 in the filter bottle 3, flows into the housing 21 through the inlet on the housing 21, and finally is output from the outlet of the housing 21; the water output from the outlet of the filter element 2 will enter the water outlet connecting pipe 12 and be output for use in the water heater.

[0089] After long-term use, the surface of the filter screen will be covered with dirt such as sediment filtered out. In this way, the filtering ability of the filter screen will decline, and then the filtering efficiency will be reduced. At this time, the sewage discharge connecting pipe 17 can be opened to clean the filter screen of the filter element 2 through the cleaning component 6.

[0090] Specifically, first, the sewage discharge connecting pipe 17 is opened, and the water introduced by the water inlet connecting pipe 11 enables the water in the filter bottle 3 to be discharged through the sewage discharge connecting pipe 17. During the process of water flow in the filter, the water flow acts on the first water flow driving part 61 of the cleaning component 6, so that the first water flow driving part 61 drives the cleaning component 6 to rotate. In this way, the dirt on the surface of the filter screen can be scraped by the first cleaning part 62 on the rotating cleaning component 6, so as to clean the dirt on the surface of the filter screen, and then the filtering ability of the filter screen is restored again, so as to ensure that the filter can maintain a high filter screen ability stably for a long time, and then the overall service life of the filter is extended.

[0091] Among them, when the sewage connection pipe 17 is in an open state, the water introduced from the water inlet connection pipe 11 enters the installation main body 1, and at least part of the water flows from the installation main body 1 into the filter bottle 3 and drives the first water flow driving part 61 to drive the cleaning component 6 to rotate on the housing 21 so as to clean the filter net 24 through the first cleaning part 62. The water flowing into the filter bottle 3 flows through the surface of the housing 21 into the sewage connection pipe 17 and is discharged.

[0092] Specifically, during use, when the sewage connection pipe 17 is opened, the water introduced by the water inlet connection pipe 11 will enter the filter bottle 3. In addition, there will also be part of the water flow introduced by the water inlet connection pipe 11 directly discharged from the sewage connection pipe 17 inside the installation main body 1 under the action of the water discharged from the sewage connection pipe 17.

[0093] By configuring a cleaning component 6 on the filter element 2, the cleaning component 6 is provided with a first water flow driving part 61 and a first cleaning part 62. The first water flow driving part 61 can drive the cleaning component 6 to rotate on the filter element 2 by using the water flow flowing in the filter. In this way, when it is necessary to clean the surface of the filter element 2 in the filter, the sewage connection pipe 17 is opened, and the water flow flowing into the filter is used to drive the cleaning component 6 to rotate to clean the filter net 24 of the filter element 2, reducing the reduction of the filtration efficiency of the filter caused by the blockage of the filter net 24 of the filter element 2 by dirt, and realizing the improvement of the filtration efficiency of the filter and the extension of the service life.

[0094] In one embodiment, in order to ensure that the cleaning component 6 can rotate reliably on the housing 21 of the filter element 2, a first supporting part 63 is provided at one end of the cleaning component 6. The first supporting part 63 abuts against the outer surface of the housing 21 and is configured to support the cleaning component 6 to rotate on the housing 21.

[0095] Specifically, the cleaning component is supported on the housing 21 through the first supporting part 63 to meet the requirement that the cleaning component can rotate on the housing 21. The first supporting part 63 is installed on the side close to the installation main body 1. Moreover, the first supporting part 63 and the first cleaning part 62 abutting against the filter net cooperate to meet the requirement that the cleaning component rotates on the housing 21.

[0096] In some embodiments, in order to improve the supporting reliability of the first supporting part 63, the first supporting part 63 is of a sleeve structure. The first supporting part 63 will be sleeved outside the housing 21 to support the rotation of the cleaning component.

[0097] In addition, in order to improve the rotational driving force generated by the cleaning component under the action of the water flow, a second water flow driving part 64 is provided on the outer surface of the first supporting part 63. The first water flow driving part 61 and the second water flow driving part 64 are arranged adjacent to each other along the rotation axis direction of the cleaning component 6; Wherein, the first water flow driving part 61 is configured to be driven by the water flow flowing towards the filter bottle 3 to drive the cleaning component 6 to rotate; The second water flow driving part 64 is configured to be driven by the water flow flowing towards the sewage connection pipe 17 to drive the cleaning component 6 to rotate.

[0098] Specifically, for the water flow flowing inside the filter, it is divided into the water flow that enters the installation main body 1 from the water inlet connection pipe 11 and flows towards the filter bottle 3, and this water flow can act on the first water flow driving part 61.

[0099] At the same time, for the water flow flowing inside the filter, it is also divided into the water flow that flows from the filter bottle 3 to the installation main body 1 and is discharged from the sewage connection pipe 17, and this water flow can act on the second water flow driving part 64.

[0100] In this way, under the driving action of the water flow, both the first water flow driving part 61 and the second water flow driving part 64 will drive the cleaning component to rotate effectively on the housing 21, so as to drive the first cleaning part 62 to effectively clean the filter screen.

[0101] In some embodiments, the first water flow driving part 61 and the second water flow driving part 64 are respectively a plurality of guiding rib strips formed on the outer peripheral direction of the cleaning component 6.

[0102] Specifically, the water flow in the filter acts on the guiding rib strips, and the guiding rib strips will generate resistance to the water flow, and use the reaction force of the water flow to drive the cleaning component to rotate.

[0103] Wherein, the guiding rib strips are arranged obliquely with respect to the rotation axis of the cleaning component 6. The inclined arrangement direction of the guiding rib strips is matched with the water flow acting on them, so that the guiding rib strips respectively constituting the first water flow driving part 61 and the second water flow driving part 64 can apply the rotational driving force in the same direction to the cleaning component.

[0104] In another embodiment, the other end of the cleaning component 6 is provided with a second supporting part 65, and the second supporting part 65 abuts against the outer surface of the housing 21 and is configured to cooperate with the first supporting part 63 to support the cleaning component 6 to rotate on the housing 21.

[0105] Specifically, the other end of the cleaning component 6 is further configured with a second supporting part 65, and the first supporting part 63 and the second supporting part 65 cooperate with each other to effectively mount the cleaning component 6 on the housing 21.

[0106] Among them, there are multiple forms for the specific structural manifestation of the second support portion 65. For example, the second support portion 65 can also adopt a sleeve structure to be sleeved on the housing 21, or the second support portion 65 is a plurality of support columns 503 to abut against the housing 21.

[0107] In another embodiment, the cleaning component 6 is integrally in a sleeve structure, and the first cleaning portion 62 is arranged on the inner wall of the cleaning component 6.

[0108] Specifically, in order to enable the cleaning component 6 to thoroughly clean the housing 21, the cleaning component 6 is in a sleeve structure to be sleeved on the outside of the housing 21, and a plurality of first cleaning portions 62 can be arranged on the inner wall of the cleaning component 6.

[0109] In addition, a second cleaning portion 66 can also be arranged on the outer wall of the cleaning component 6, and the second cleaning portion 66 abuts against the inner wall of the filter bottle 3 to clean the inside of the filter bottle 3 through the second cleaning portion 66.

[0110] The first cleaning portion 62 and the second cleaning portion 66 are in a strip structure and extend along the rotation axis direction of the cleaning component 6. Moreover, the first cleaning portion 62 and the second cleaning portion 66 can be made of a flexible material such as silica gel or rubber to enable the first cleaning portion 62 and the second cleaning portion 66 to closely adhere to the surface to be cleaned.

[0111] The surface of the cleaning component 6 is provided with a hollow structure to allow the water in the filter bottle 3 to enter the inside of the cleaning component 6 through the hollow structure for filtration by the filter element 2.

[0112] In another embodiment of the present application, for the sewage discharge connecting pipe 17, an independent valve assembly 7 can be externally connected to control the opening and closing of the controller, or a valve assembly 7 can also be integrally provided on the sewage discharge connecting pipe 17.

[0113] Specifically: The valve assembly 7 includes a valve body 71 and a rotating member 72. The valve body 71 is rotatably arranged in the sewage discharge connecting pipe 17, the rotating member 72 is arranged on the valve body 71, and the rotating member 72 extends out of the pipe wall of the sewage discharge connecting pipe 17; the valve body 71 is configured to open and close the sewage discharge connecting pipe 17.

[0114] Specifically, the valve body 71 is located in the sewage discharge connecting pipe 17 and can rotate in the sewage discharge connecting pipe 17 to control the opening and closing of the sewage discharge connecting pipe 17 through the rotating valve body 71. The rotating member 72 for driving the valve body 71 to rotate extends outside the pipe wall of the sewage discharge connecting pipe 17, and then drives the valve body 71 in the sewage discharge connecting pipe 17 to rotate by driving the rotating member 72 to rotate.

[0115] Among them, for the specific structure of the valve body 71, the structure of the valve body 71 in a conventional valve can be adopted. For example: the valve body 71 can be a spherical structure, and a water flow hole is arranged vertically on the sphere perpendicular to its axis, and the sphere is rotated to control the position of the water flow hole to realize the on-off of the exhaust connection pipe; or, the valve body 71 can be a valve plate, and the valve plate is rotated to control the opening and closing of the exhaust connection pipe.

[0116] In one embodiment, in order to facilitate the user to open and close the valve body 71 during actual use, the valve assembly 7 further includes a driving handle 73, and the driving handle 73 is rotatably arranged on the sewage discharge connection pipe 17 and is configured to drive the rotating member 72 to rotate.

[0117] Specifically, the driving handle 73 is rotatably installed on the exhaust connection pipe. When the user rotates the driving handle 73 by hand, the rotating member 72 can be driven to drive the valve body 71 to rotate, so as to realize the opening and closing of the sewage discharge connection pipe 17.

[0118] In some embodiments, in order to meet the user's labor-saving operation and achieve a compact structure design, a passive gear structure 74 is provided on the rotating member 72, and an active gear structure 75 is provided on the driving handle 73, and the passive gear structure 74 and the active gear structure 75 are engaged.

[0119] Specifically, a passive gear structure 74 is provided at the end of the rotating member 72 extending outside the sewage discharge connection pipe 17. At the same time, an active gear structure 75 is configured on the driving handle 73, and the driving handle 73 is rotated to drive the rotating member 72 to rotate labor-savingly through the meshing cooperation of the active gear structure 75 and the passive gear structure.

[0120] In another embodiment, in order to conveniently integrate and assemble the driving handle 73 onto the sewage discharge connection pipe 17, the valve assembly 7 further includes a connecting member 76. The connecting member 76 is arranged at the pipe orifice of the sewage discharge connection pipe 17. A sewage discharge hole 761 is provided on the connecting member 76, and the sewage discharge hole 761 is communicated with the sewage discharge connection pipe 17; an installation hole 731 is provided on the driving handle 73, and the connecting member 76 and / or the sewage discharge connection pipe 17 are inserted into the installation hole 731; the connecting member 76 is configured to prevent the driving handle 73 from falling off the sewage discharge connection pipe 17.

[0121] Specifically, the driving handle 73 needs to be integrally installed on the sewage connection pipe 17 and can rotate on the sewage connection pipe 17. For this purpose, an installation hole 731 is provided on the driving handle 73, and by means of the installation hole 731, the driving handle 73 can rotate relative to the sewage connection pipe 17. The connecting piece 76 is connected to the pipe orifice of the sewage connection pipe 17 so that the driving handle 73 is located between the connecting piece 76 and the passive gear structure 74. On the one hand, it can ensure that the active gear structure 75 can reliably mesh with the passive gear structure 74. On the other hand, the connecting piece 76 can ensure that the driving handle 73 is reliably installed on the sewage connection pipe 17 to meet the requirements of integrated installation.

[0122] Among them, for the driving handle 73, it can be directly sleeved outside the sewage connection pipe 17 to meet the requirement of rotatable installation. Or, a stepped structure can be provided on the connecting piece 76, and the driving handle 73 is rotatably installed on the stepped structure through the installation hole 731 to limit the driving handle 73 by the stepped surface of the stepped structure.

[0123] In another embodiment, as Figures 9 - 16 shown, in the filter provided by another embodiment of the present application, in order to facilitate the connection between different waterways in the installation main body 1, based on the above-mentioned first embodiment, a water distributor 5 is further provided, and the water distributor 5 is used to meet the waterway connection requirements between the water inlet connection pipe 11, the water outlet connection pipe 12, the sewage connection pipe 17 and the filter element 2.

[0124] Specifically: The installation main body 1 is provided with an open installation cavity, and a first connection port 13 is provided at the open end of the installation cavity. A second connection port 14 is further provided inside the installation cavity at the position of the first connection port 13.

[0125] The water distributor 5 is provided with a first water flow interface 55, a second water flow interface 57 and a third water flow interface 56.

[0126] Among them, the water distributor 5 is arranged on the second connection port 14, the filter bottle 3 is arranged on the first connection port 13 and is hermetically connected to the water distributor 5. An outlet water cavity is formed between the water distributor 5 and the inner wall of the installation main body 1, and an inlet water cavity is formed between the water distributor 5 and the filter bottle 3; the filter element 2 and the cleaning component 6 are arranged between the water distributor 5 and the filter bottle 3, and the cleaning component 6 is rotatably sleeved on the housing 21; The water inlet connection pipe 11 is communicated with the inlet through the first water flow interface 55, the water outlet connection pipe 12 is communicated with the outlet through the second water flow interface 57, and the sewage connection pipe 17 is communicated with the internal space of the filter bottle 3 through the third water flow interface 56.

[0127] Specifically, a water distributor 5 is built into the installation main body 1. The water distributor 5 forms an independent water outlet cavity in the installation main body 1 to be directly connected to the water outlet connecting pipe 12, and a water inlet cavity is formed between the water distributor 5 and the outer filter bottle 3 in the installation main body 1 to meet the requirement of connecting to the water inlet connecting pipe 11.

[0128] Correspondingly, a first water flow interface 55, a second water flow interface 57, and a third water flow interface 56 are provided on the water distributor 5 to meet the water connection requirements of the water inlet connecting pipe 11, the water outlet connecting pipe 12, and the sewage connecting pipe 17 configured on the installation main body 1.

[0129] During use, the water flowing into the inner side of the water distributor 5 through the first water flow interface 55 will act on the first water flow driving part 61, causing the first water flow driving part 61 to drive the cleaning part 6 to rotate on the housing 21 under the drive of the water flow. Furthermore, the first cleaning part 62 is driven to rotate with the cleaning part 6 to scrape the filter net 24 on the housing 21.

[0130] In some embodiments, for the water distributor 5, it has an end plate part 501 and an annular part 502. The first water flow interface 55 and the third water flow interface 56 are provided on the annular part 502, and the second water flow interface 57 is provided on the end plate part 501.

[0131] Specifically, the water distributor 5 is in the shape of a cover shell. The end plate part 501 of the water distributor 5 is used to form a water outlet cavity at intervals inside the installation cavity of the installation main body 1. And the water outlet cavity can be connected to the inlet of the filter element 2 through the second water flow interface 57.

[0132] On the annular part 502 of the water distributor 5, a first water flow interface 55 and the third water flow interface 56 are configured to connect the water inlet connecting pipe 11 and the sewage connecting pipe 17 respectively.

[0133] Among them, after the water distributor 5 is installed in the installation main body 1, the end of the filter element 2 with an inlet is connected to the second water flow interface 57 and is surrounded by the annular part 502. And a connection and cooperation structure with a sealed connection is formed between the annular part 502, the filter bottle 3, and the installation main body 1, so that a water inlet cavity is formed between the water distributor 5 and the filter bottle 3. In this way, the water conveyed by the water inlet connecting pipe 11 enters the water inlet cavity, the water in the water inlet cavity is filtered by the filter net 24 of the filter element 2 and is output from the outlet of the filter element 2. The water output from the filter element 2 flows into the water outlet cavity through the second water flow interface 57 and is finally output from the water outlet connecting pipe 12.

[0134] In certain embodiments, a plurality of support columns 503 are provided on the end plate part 501. The support columns 503 are located in the water outlet cavity and abut against the installation main body 1.

[0135] Specifically, in order to locate the installation position of the water diverter 5, a plurality of support columns 503 may be provided on the end plate portion 501. After the water diverter 5 is assembled into the installation cavity of the installation main body 1, the support columns 503 abut against the inner wall of the installation cavity to form a water outlet cavity at intervals between the water diverter 5 and the installation main body 1. Among them, the plurality of support columns 503 are distributed around the second water flow interface 57.

[0136] In some embodiments, a diversion channel 504551 is further provided on the inner wall of the annular portion 502. The diversion channel 504551 communicates with the first water flow interface 55, and the water outlet holes of the diversion channel 504551 face the first water flow driving portion 61.

[0137] Specifically, in order to effectively drive the cleaning component 6 to rotate rapidly on the filter element 2, the water flowing into the water inlet cavity needs to effectively impact the first water flow driving portion 61 on the cleaning component 6. For this purpose, a diversion channel 504551 is provided on the inner wall of the annular portion 502 to guide the water flowing in from the first water flow interface 55. The water outlet holes of the diversion channel 504551 discharge water in the direction of the first water flow driving portion 61, and the water output from the water outlet holes of the diversion channel 504551 will act on the first water flow driving portion 61, thereby ensuring that the first water flow driving portion 61 bears a sufficient large water pressure to drive the cleaning component 6 to rotate.

[0138] Similarly, one end portion of the cleaning component 6 is provided with a first support portion 63. The first support portion 63 abuts against the outer surface of the housing 21 and is configured to support the cleaning component 6 to rotate on the housing 21. The annular portion 502 is located outside the first support portion 63.

[0139] The first support portion 63 is of a sleeve structure, and a second water flow driving portion 64 is provided on the outer surface of the first support portion 63. The first water flow driving portion 61 and the second water flow driving portion 64 are arranged adjacent to each other along the rotation axis direction of the cleaning component 6; Among them, the first water flow driving portion 61 is configured to be driven by the water flow flowing in the direction of the filter bottle 3 to drive the cleaning component 6 to rotate; The second water flow driving portion 64 is configured to be driven by the water flow flowing in the direction of the sewage connection pipe 17 to drive the cleaning component 6 to rotate.

[0140] Specifically, for the first support portion 63, it is located in the space formed by the surrounding of the annular portion 502, and a third water flow interface 56 is further provided on the annular portion 502. In this way, the water flowing out from the third water flow interface 56 can be further used to act on the second water flow driving portion 64 to increase the rotation speed of the water flow driving the cleaning component 6.

[0141] In another embodiment, in order to reduce the mutual influence between the water flows received by the first water flow driving part 61 and the second water flow driving part 64, the cleaning component 6 is integrally of a sleeve structure, and the first cleaning part 62 is arranged on the inner wall of the cleaning component 6; a plurality of connecting ribs 67 are provided between the first supporting part 63 and the cleaning component 6, and a water flow interval is formed between two adjacent connecting ribs 67, and the water flow interval is configured to output water flow towards the second water flow driving part 64.

[0142] Specifically, for the diversion channel 504551, the water outlet direction of its diversion channel 504551 is towards the water outlet of the filter bottle 3 to generate a water flow impact on the first water flow driving part 61 in its water outlet direction. The water entering the filter bottle 3 can flow between the cleaning component 6 and the filter element 2 and flow back to the third water flow interface 56 of the water distributor 5. During the process of the water flowing back to the water distributor 5, it can flow out through the water flow interval between the two connecting ribs 67 to avoid the first water flow driving part 61 on the outer wall of the cleaning component 6; moreover, the water flowing out from the water flow interval flows onto the surface of the first supporting part 63 to generate a water flow impact on the second water flow driving part 64, thereby better meeting the requirement of using the water flow to drive the cleaning component 6 to rotate.

[0143] In some embodiments, a second cleaning part 66 is further provided on the outer wall of the cleaning component 6, and the second cleaning part 66 abuts against the inner bottle wall of the filter bottle 3. The first cleaning part 62 and the second cleaning part 66 are in a strip structure and extend along the rotation axis direction of the cleaning component 6. A hollow structure is provided on the surface of the cleaning component 6. And, in order to ensure reliable support for both ends of the cleaning component 6 respectively, a second supporting part 65 can be provided at the other end of the cleaning component 6, and the second supporting part 65 abuts against the outer surface of the housing 21 and is configured to cooperate with the first supporting part 63 to support the cleaning component 6 to rotate on the housing 21. For specific details, reference can be made to the description in the first embodiment above, and details will not be elaborated here.

[0144] In some embodiments, in order to facilitate the user to directly observe the usage state of the filter element 2 in the filter bottle 3 and replace the filter element 2 in time when the water quality is poor, the filter bottle 3 is of a transparent structure or a semi-transparent structure.

[0145] Specifically, since the filter bottle 3 is made of a transparent or semi-transparent material, when the user uses it, the state of the filter element 2 in the filter bottle 3 can be directly observed, and thus, when the water quality condition is poor, the replacement cycle of the filter element 2 can be shortened.

[0146] Embodiment 3, in another embodiment of the present application, for the installation main body, it can be of an integral structure, and for the convenience of processing, the installation main body can also adopt a split structure, which will be described below with reference to the drawings.

[0147] As shown Figure 7 in the figure, the installation main body 1 includes a first installation component 15 and a second installation component 16. The water inlet connecting pipe 11 and the water outlet connecting pipe 12 are arranged on the first installation component 15. An installation cavity is formed in the second installation component 16. A first connection port 13, a second connection port 14, and a sewage connecting pipe 17 are arranged on the second installation component 16. The first installation component 15 and the second installation component 16 are fixedly connected together. The water inlet connecting pipe 11, the water outlet connecting pipe 12, and the sewage connecting pipe 17 are respectively communicated with the installation cavity. The inlet of the filter element 2 is located in the filter bottle 3, and the outlet of the filter element 2 is located in the installation cavity.

[0148] Specifically, for the installation main body 1, since two independent water flow requirements of water inlet and water outlet need to be satisfied inside it, in order to simplify the processing difficulty, the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are arranged on the first installation component 15, and the sewage connecting pipe 17 is arranged on the second installation component 16.

[0149] In order to meet the requirements of water inlet and water outlet inside the installation main body 1 and meet the installation design requirements of structural compactness and miniaturization, the following structural improvements are made to the installation main body 1.

[0150] The first installation component 15 is a three-way pipe. The three ends of the three-way pipe respectively form the water inlet connecting pipe 11, the water outlet connecting pipe 12, and the auxiliary connecting pipe 153. The water inlet connecting pipe 11 and the auxiliary connecting pipe 153 are arranged in a back-to-back manner; A communication port is arranged on the second installation component 16, and the communication port communicates with the installation cavity.

[0151] The filter also includes an intermediate pipe 4. The intermediate pipe 4 is arranged in the water inlet connecting pipe 11. The outer end of the intermediate pipe 4 is hermetically connected to the inner pipe wall of the water inlet connecting pipe 11. The water inlet of the water inlet connecting pipe 11 communicates with the intermediate pipe 4. The inner end of the intermediate pipe 4 passes through the communication port and extends into the installation cavity. An auxiliary flow channel 111 is formed between the outer pipe wall of the intermediate pipe 4 and the inner pipe wall of the water inlet connecting pipe 11. The water outlet connecting pipe 12 communicates with the water outlet cavity through the auxiliary flow channel 111 and the communication port. The inner pipe orifice of the intermediate pipe 4 communicates with the water inlet cavity.

[0152] Specifically, for the first installation component 15, its overall structure is a three-way pipe structure, and correspondingly, the water inlet connecting pipe 11 and the water outlet connecting pipe 12 are formed. The other pipe orifice of the three-way pipe will form the auxiliary connecting pipe 153 to be connected with the communication port of the second installation component 16 through the auxiliary connecting pipe 153.

[0153] For the water inlet connecting pipe 11 and the water outlet connecting pipe 12 on the first mounting member 15, they need to meet the requirements of water inlet and outlet. By arranging an intermediate pipe 4 in the water inlet connecting pipe 11, an auxiliary flow channel 111 can be formed between the intermediate pipe 4 and the inner pipe wall of the water inlet connecting pipe 11. The first mounting member 15 has a three-way pipe structure, so that the auxiliary flow channel 111 communicates with the water outlet connecting pipe 12. After the first mounting member 15 is connected to the second mounting member 16, the auxiliary connecting pipe 153 is connected to the communication port, so that the auxiliary flow channel 111 communicates with the water outlet cavity through the communication port. At the same time, the pipe orifice at the inner end of the intermediate pipe 4 extends into the mounting cavity of the second mounting member 16 through the auxiliary connecting pipe 153 and the communication port to achieve communication with the water inlet cavity.

[0154] An auxiliary flow channel 111 is formed in the water inlet connecting pipe 11 by using the intermediate pipe 4 to meet the connection requirement between the water outlet connecting pipe 12 and the water outlet cavity, making the overall structure of the first mounting member 15 more compact and small, thereby meeting the design requirements of miniaturization.

[0155] The water distributor 5 arranged in the mounting cavity of the second mounting member 16 is used to separate the water outlet cavity and the water inlet cavity in the mounting cavity of the second mounting member 16. A protruding annular spacer 51 is arranged on the annular portion on one side of the communication port, so that the water inlet cavity and the water outlet cavity are separated in the mounting cavity of the second mounting member 16.

[0156] In some embodiments, a plugging portion 54 is arranged on the annular portion, and a first water flow interface 55 arranged opposite to the communication port is arranged on the plugging portion 54. The first water flow interface 55 communicates with a diversion channel 551 on the inner wall of the annular portion; The inner end of the intermediate pipe 4 is hermetically inserted into the first water flow interface 55, and the inner pipe orifice of the intermediate pipe 4 communicates with the water inlet cavity through the diversion channel 551.

[0157] During the assembly process, the inner end of the intermediate pipe 4 is inserted into the first water flow interface 55, so that the intermediate pipe 4 communicates with the water inlet cavity through the diversion channel 551. Moreover, the intermediate pipe 4 and the plugging portion 54 cooperate with each other so that the inner port of the intermediate pipe 4 can be isolated from the water outlet cavity, thereby meeting the effective isolation between the water inlet cavity and the water outlet cavity.

[0158] In addition, by arranging the plugging portion 54 on the annular portion, it can better meet the flow requirement of the water outlet flow by borrowing the internal flow channel of the water inlet connecting pipe 12. At the same time, during the overall assembly of the filter, it is convenient to effectively connect the inner end of the intermediate pipe 4 to the water inlet cavity while also meeting the effective isolation from the water outlet cavity, facilitating the quick and precise assembly of the filter.

[0159] In order to further increase the space at the water inlet of the water outlet connecting pipe 12, a concave structure 41 can also be provided on the intermediate pipe 4. The concave structure 41 is arranged opposite to the water inlet of the water outlet connecting pipe 12. In this way, the water collected and delivered by the auxiliary flow channel 111 can flow more smoothly into the water outlet connecting pipe 12 at the concave structure 41, so as to ensure the smooth flow of the water outlet flow.
