Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a switch-integrated filter. Background Technology

[0002] Filters are common water treatment devices. Their core function is to remove impurities such as suspended solids, particles, heavy metals and microorganisms from water sources through physical or chemical means. However, filters are often equipped with an inlet valve at the input end and are often connected to pipelines at the output end.

[0003] On the one hand, after the water is used up at the output end, the water in the pipe is prone to backflow due to gravity or pressure fluctuations. This causes the purified water to mix with the unfiltered original water source or pollutants in the pipe, which not only increases the risk of secondary pollution of the water source, but also easily accelerates the clogging of the filter element due to the deposition of pollutants and shortens the service life of the filter element, thus reducing the filtration quality of the filter.

[0004] On the other hand, the filter's connection pipes are cumbersome and complex, take up a lot of space, and increase the number of connection points, which increases the risk of leakage and affects the user experience of the filter. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a switch-integrated filter that not only prevents water backflow from contaminating the water source, but also improves the filter's integration, reduces the space required for installation, and enhances the user experience.

[0006] According to a first aspect of the present invention, an integrated switch filter includes a housing, a filter mechanism, and a water-stopping mechanism. The housing has an inner cavity, and an inlet pipe and an outlet pipe communicating with the inner cavity are provided in the housing. The inlet pipe is equipped with a switch valve for opening or closing the inlet pipe. The filter mechanism is detachably connected to the inner cavity and is arranged between the inlet pipe and the outlet pipe, and is used to filter water. The water-stopping mechanism includes a check valve and a sealing ring. The check valve is fixedly connected to the inlet pipe, and the switch valve is arranged between the check valve and the filter mechanism. The check valve is used to prevent water from flowing from the filter mechanism to the inlet pipe, and the sealing ring is arranged between the check valve and the inlet pipe.

Opening the switch valve allows water to flow sequentially through the inlet pipe, the filter mechanism, and the outlet pipe, thereby filtering the water. By arranging the switch valve inside the housing, not only is it convenient to open or close the water flow, but it also improves the integration of the filter, reduces the number of connecting pipes, lowers the risk of leakage, and improves the user experience. Furthermore, the check valve arranged in the inlet pipe prevents water from flowing from the filter mechanism towards the inlet pipe, preventing backflow of water in the external pipe that could flush away contaminants and reducing the possibility of contaminants adhering to the filter mechanism. Furthermore, the sealing ring is placed between the check valve and the inlet pipe, which enhances the sealing of the connection between the check valve and the inlet pipe, preventing water from flowing through the gap between the check valve and the inlet pipe. This not only enhances the filtration stability of the water flow but also prevents water from flowing back into the inlet pipe and contaminating the water source.

[0013] According to some embodiments of the present invention, the filter element is fixedly connected to a positioning ring, the positioning ring is provided with a through groove in the circumferential direction, the inner sidewall and the outer sidewall of the positioning ring are provided with positioning blocks protruding from them, and the positioning blocks are arranged adjacent to the through groove. The filter element is rotatably connected to two scale plates, the scale plates are provided with multiple positioning grooves in the circumferential direction, and the positioning blocks can be inserted into the positioning grooves.

[0014] According to some embodiments of the present invention, the housing includes a first outer shell and a second outer shell, the first outer shell and the second outer shell being threadedly connected to form the inner cavity, and the second outer shell being configured as a transparent component.

Detailed Implementation

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0024] Understandably, referring to Figures 1 to 3 The integrated filter of the present invention includes a housing 100, a filter mechanism 200, and a water-stopping mechanism 300. The housing 100 is provided with an inner cavity 110, and the housing 100 has an inlet pipe 111 and an outlet pipe 112 communicating with the inner cavity 110. The inlet pipe 111 is equipped with a switch valve 113, which is used to open or close the inlet pipe 111. The filter mechanism 200 is detachably connected to the inner cavity 110, and the filter mechanism 200 is arranged at the inlet pipe. Between pipe 111 and outlet pipe 112, filter mechanism 200 is used to filter water; water-stopping mechanism 300 includes check valve 310 and sealing ring 320. Check valve 310 is fixedly connected to inlet pipe 111, and switch valve 113 is arranged between check valve 310 and filter mechanism 200. Check valve 310 is used to block water flow from filter mechanism 200 to inlet pipe 111, and sealing ring 320 is arranged between check valve 310 and inlet pipe 111.

[0025] The housing 100 has an inner cavity 110, and the filter mechanism 200 is detachably connected to the inner cavity 110. Both the inlet pipe 111 and the outlet pipe 112 are connected to the inner cavity 110. A switch valve 113 is arranged in the inlet pipe 111. Opening the switch valve 113 allows water to flow sequentially through the inlet pipe 111, the filter mechanism 200, and the outlet pipe 112, thereby filtering the water. By arranging the switch valve 113 within the housing 100, not only is it convenient to turn the water flow on or off, but it also improves the integration of the filter, reduces the number of connecting pipes, lowers the risk of leakage, reduces the space required for installation, and enhances the user experience.

[0026] The check valve 310 is arranged in the inlet pipe 111, which can block the flow of water from the filter mechanism 200 to the inlet pipe 111. This not only prevents backflow of water from contaminating the inlet pipe 111 side, keeping the water source isolated from the outside world and avoiding secondary pollution, but also prevents backflow of water in the external pipe from washing away contaminants, reducing the possibility of contaminants adhering to the filter mechanism 200. Furthermore, the sealing ring 320 is arranged between the check valve 310 and the inlet pipe 111, which enhances the sealing of the connection between the check valve 310 and the inlet pipe 111, preventing water from passing through the gap between them. This not only enhances the filtration stability of the water flow but also prevents backflow of water to the inlet pipe 111 from contaminating the water source. Moreover, after the switch valve 113 is closed, it also prevents water from flowing towards the check valve 310, further preventing backflow. This helps extend the service life of the filter mechanism 200 and improves the reliability of the filter.

[0027] It should be noted that the outlet pipe 112 is connected to a pipeline, so after water flows from the outlet pipe 112 into the pipeline, impurities deposited in the pipeline and external pollutants will mix with the water. This may result in the water containing substances that the filter mechanism 200 cannot filter. When the water flows back into the inner cavity 110 along the pipeline, it will cause cross-contamination of the water on the inlet pipe 111 side, which will not only affect the filtration effect of the filter mechanism 200, but may also clog or even damage the filter mechanism 200. The check valve 310 can prevent the backflow of water, and the sealing ring 320 can seal the gap between the housing 100 and the check valve 310, preventing water from seeping in through the gap between the housing 100 and the check valve 310, thus ensuring the filtration effect and enhancing the reliability of the filter.

[0028] In addition, the switch valve 113 is arranged inside the housing 100 so that the external water source can be directly connected to the water inlet pipe 111 without the need to install a water inlet valve between the water source and the filter. This enables the filter to have a water flow cut-off control function, which not only improves the convenience of water circuit connection, but also reduces the space required to install the filter. It is easy to adapt to installation in narrow spaces such as the back of the washing machine and the bottom of the sink, thus improving the user experience.

[0029] Specifically, the switching valve 113 can be a ball valve, angle valve, butterfly valve, plug valve, etc., which will not be described in detail here.

[0030] Specifically, the filter mechanism 200 is detachably connected to the inner cavity 110, and its service life can be extended by replacement, thereby reducing the maintenance cost of the filter and improving the convenience of use.

[0031] Specifically, the filtration mechanism 200 may include a filter screen, activated carbon, scale inhibitor, etc., which will not be described in detail here.

[0032] Understandably, referring to Figure 3 and Figure 4 The filtration mechanism 200 includes a filter element 210 and a filter screen 220. The filter element 210 has a cavity 211 and a through hole 212. The cavity 211 houses filter media (not shown in the attached figure) and is connected to the inlet pipe 111. The two sides of the through hole 212 are connected to the cavity 211 and the outlet pipe 112, respectively. The filter screen 220 is fixedly connected to the side of the through hole 212 away from the cavity 211. Both the filter media and the filter screen 220 are used to filter water. The filter element 210 is arranged in the inner cavity 110, and the filter media is arranged in the cavity 211. When water flows through the filtration mechanism 200, the water flows sequentially through the cavity 211, the through hole 212, the filter screen 220, and the outlet pipe 112. The filter media and the filter screen 220 can filter the water, allowing the filter media to remove most pollutants and improve the basic purity of the water. Furthermore, the filter screen 220 can further intercept tiny impurities, improving the quality of the output water.

[0033] In addition, the filter screen 220 can block backflow water from entering the chamber 211, preventing impurities from adhering to the filter media, thereby maintaining the filtration effect of the filter media and extending its service life.

[0034] Specifically, refer to Figure 3 and Figure 4 The outer wall of the filter element 210 has a groove 213, and a through hole 212 is arranged in the groove 213 so that the filter screen 220 and the through hole 212 are arranged at intervals. The through hole 212 is arranged in the groove 213, so that the filter screen 220 and the through hole 212 are arranged at intervals. This allows the water flow to be contained in the groove 213 after passing through the through hole 212, so as to buffer the impact of the water flow on the filter screen 220 and make the water flow evenly distributed on the surface of the filter screen 220. This avoids the water flow from concentrating and impacting the filter screen 220 locally, which would cause premature clogging in that area, thus extending the service life of the filter screen 220 and improving the filtration efficiency.

[0035] The number of through holes 212 is set to multiple, and the multiple through holes 212 are arranged at intervals in the filter element 210 to disperse the flow of water, so that the water can pass through the filter screen 220 evenly, making it easier for the water to cover the entire filtration area of ​​the filter screen 220 and extend the service life of the filter screen 220.

[0036] Specifically, refer to Figure 3 and Figure 4 The filtration mechanism 200 also includes a water distribution block 230, which is fixedly connected to the water inlet end of the filter element 210. The water distribution block 230 has multiple water distribution holes 231 spaced apart, and the multiple water distribution holes 231 are connected to the cavity 211. The water distribution block 230 is fixedly connected to the water inlet end of the filter element 210. When water flows in from the water inlet pipe 111, it first passes through the water distribution block 230, and the multiple water distribution holes 231 evenly disperse the water flow into multiple fine streams before flowing into the cavity 211, so that the water flow can fully contact the filter material, thereby improving the filtration efficiency and effect.

[0037] At the same time, the evenly distributed water flow reduces the impact on the filter media, avoiding the possibility of damage and failure caused by concentrated water flow, extending the service life of the filter media, and thus extending the service life of the entire filtration mechanism by 200, reducing the maintenance cost of the filter.

[0038] Specifically, refer to Figure 3 and Figure 4The filter element 210 is provided with a connecting cylinder 214. The side wall of the connecting cylinder 214 has a connecting hole 215 that connects to the cavity 211. The water distribution block 230 is provided with an adjusting pipe 232. The adjusting pipe 232 has an adjusting hole 233. The adjusting pipe 232 is rotatably connected inside the connecting cylinder 214 so that the adjusting hole 233 can communicate with the connecting hole 215. The filter element 210 is provided with a connecting cylinder 214, which is located in the middle of the cavity 211. The adjusting pipe 232 is rotatably connected inside the connecting cylinder 214. By driving the water distribution block 230 to rotate, the adjusting pipe 232 can rotate inside the connecting cylinder 214, so that the adjusting hole 233 can communicate with or be offset from the connecting hole 215, thereby guiding the flow path of the water and adjusting the filtration intensity of the filtration mechanism 200.

[0039] When the regulating hole 233 is misaligned with the connecting hole 215, the water flows in from the water distribution block 230 and is dispersed into multiple fine streams through the water distribution hole 231, which then enter from the end of the cavity 211 and are output from the through hole 212 after passing through the filter material. When the regulating hole 233 is connected to the connecting hole 215, water flows in from the water distribution block 230. Part of the water passes through the water distribution hole 231, and the other part of the water enters the regulating pipe 232. The water passing through the water distribution hole 231 enters at the end of the cavity 211, and the water passing through the regulating pipe 232 enters the middle of the cavity 211 through the regulating hole 233. Then all the water passes through the filter material and is output from the through hole 212. It should be noted that by rotating the water distribution block 230, the regulating hole 233 can be connected to the connecting hole 215, thereby allowing at least a portion of the water to flow to the middle of the cavity 211, which prolongs the contact time between the water and the filter media, enhances the filtration effect, and improves reliability.

[0040] Specifically, refer to Figure 3 and Figure 4The filter element 210 has multiple adjustment grooves 216 arranged circumferentially. The water distribution block 230 is slidably connected to the adjustment block 234 in the radial direction. An elastic element 235 is provided between the water distribution block 230 and the adjustment block 234. The elastic element 235 is used to drive the adjustment block 234 to move away from the water distribution block 230 so that the adjustment block 234 can be inserted into the adjustment groove 216. The adjusting block 234 is slidably connected to the filter element 210 so that the adjusting block 234 can slide radially along the filter element 210. The filter element 210 has multiple adjusting grooves 216 circumferentially. One end of the elastic member 235 abuts against the filter element 210 and the other end abuts against the adjusting block 234 so as to push the adjusting block 234 to move away from the filter element 210 so that the adjusting block 234 can be inserted into the adjusting groove 216 so that the water distribution block 230 can be stably placed on the filter element 210, preventing the water distribution block 230 from shaking or shifting in the filter element 210, so that the position of the adjusting hole 233 and the connecting hole 215 can be kept stable, thereby enabling the adjusting hole 233 and the connecting hole 215 to be connected or misaligned, or adjusting the opening of the connecting hole 215, improving the reliability of the filtration mechanism 200.

[0041] It should be noted that the elastic element 235 can be a spring, or a rubber or silicone component, or other elastic element, which will not be elaborated here.

[0042] Specifically, refer to Figure 4 and Figure 5 The filter element 210 is fixedly connected to a positioning ring 240. The positioning ring 240 has a circumferentially circumferentially open through groove 241. Positioning blocks 242 protrude from both the inner and outer walls of the positioning ring 240, and are arranged adjacent to the through groove 241. The filter element 210 is rotatably connected to two scale plates 243. Multiple positioning grooves 244 are spaced apart circumferentially on the scale plates 243, and the positioning blocks 242 can be engaged in the positioning grooves 244. The positioning ring 240 is fixedly connected to the filter element 210, and the positioning blocks 242 protrude from both the inner and outer walls of the positioning ring 240. Both scale plates 243 are rotatably connected to the filter element 210. By rotating the scale plates 243, the positioning blocks 242 can be engaged in different positioning grooves 244, thus ensuring that the scale plates 243 are stably positioned within the positioning ring 240.

[0043] The scale plate 243 has multiple time markings along its circumference, such as year and month markings. The filter element 210 has a pointer marking. By rotating the scale plate 243, the pointer marking can be aligned with the time markings, so that the user can know the usage time of the filter element 210 and replace the filter element 210 in a timely manner.

[0044] It should be noted that the positioning ring 240 is made of plastic. By opening a through groove 241 on the positioning ring 240 and arranging the positioning block 242 adjacent to the through groove 241, the positioning ring 240 can be elastically deformed, allowing the positioning block 242 to move smoothly along the radial direction of the positioning ring 240. This facilitates the movement of the positioning block 242 between multiple positioning grooves 244, which not only improves the positional stability of the scale plate 243 but also enhances the rotation feel of the scale plate 243, thereby improving the user experience.

[0045] Understandably, referring to Figure 3 and Figure 6 The housing 100 includes a first outer shell 120 and a second outer shell 130, which are threadedly connected to form an inner cavity 110. The second outer shell 130 is a transparent component. By setting the first outer shell 120 and the second outer shell 130 to be threadedly connected, the filter mechanism 200 can be easily installed in or removed from the inner cavity 110, reducing the maintenance difficulty of the filter and improving the user experience.

[0046] In addition, the second housing 100 is a transparent component, which allows users to directly observe the working status of the internal filter mechanism 200 without disassembling the filter. This makes it easier for users to determine whether the filter mechanism 200 needs to be replaced, avoiding the impact on the filtration effect due to overuse or damage to the filter mechanism 200, effectively extending the overall service life of the filter and improving the filtration quality.

[0047] It should be noted that the second shell 100 can be made of transparent materials such as polydodecyl lactam, acrylic, or glass, which will not be elaborated here.

[0048] Specifically, refer to Figure 2 and Figure 6 The second housing 130 is connected to a rotating ring 131, which is fixedly connected to the second housing 130 along its circumference. A lever 132 is fixedly connected to the rotating ring 131, and the lever 132 is arranged radially along the rotating ring 131. The rotating ring 131 is connected to the second housing 130, and is fixedly connected to the second housing 130 along its circumference. The lever 132 is arranged radially along the rotating ring 131. By rotating the lever 132, the rotational arm of the second housing 130 is increased, making it easier for the user to apply force and allowing the second housing 100 to be easily removed from the first housing 100. This facilitates the assembly and disassembly of the filter and improves ease of use.

[0049] Specifically, refer to Figure 2 and Figure 6The second outer shell 130 has multiple connecting grooves 133 arranged around the circumference of the second outer shell 130. Along the axial direction of the second outer shell 130, the width of the connecting grooves 133 gradually increases towards the first outer shell 120. The inner sidewall of the rotating ring 131 is provided with a connecting part 134 protruding from it. The connecting part 134 is fitted into the connecting groove 133, and the shape of the connecting part 134 matches that of the connecting groove 133. Multiple connecting grooves 133 are arranged circumferentially along the second outer shell 130, and the width of the connecting grooves 133 gradually increases along the axial direction of the second outer shell 130 towards the first outer shell 120. By setting the shape of the connecting part 134 to match the connecting groove 133, not only can the connecting part 134 be stably placed in the connecting groove 133, increasing the contact area between the connecting part 134 and the wall of the connecting groove 133, but it also facilitates the connection of the rotating ring 131 to the second outer shell 130, improving the connection stability between the rotating ring 131 and the second outer shell 130, making it easier for the rotating ring 131 to push the second outer shell 130 to rotate, and improving the convenience of use.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
