Description

Technical Field

[0001] This utility model relates to the technical field of filters, and in particular to a multifunctional filter. Background Technology

[0002] A pre-filter, also known as a filter, is a water purification product for the main pipeline. It is installed on the water pipe from the water meter to the first water tap in the house. The pre-filter can ensure that impurities in the water supply network will not cause harm to the human body and play a pre-protection role for indoor water-related equipment (such as water softeners, water purifiers, pure water machines, direct drinking water machines, etc.).

[0003] After use, impurities filtered from the raw water are collected inside the pre-filter. When a large amount of impurities accumulate, the pre-filter needs to be cleaned to ensure its filtration efficiency. Existing filters only have filtration and rinsing functions, which are limited. When the filter element is clogged, the filter cannot flow water. Furthermore, the sewage discharge channel and the inlet / outlet water channel in existing filters are set far apart. For example, the inlet / outlet water channel is located in the filter valve body, while the sewage discharge channel is located at the bottom of the filter cartridge. This requires corresponding valve devices for the sewage discharge channel and the inlet / outlet water channel, resulting in a complex overall filter structure.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] This invention addresses the shortcomings of existing filters mentioned above by proposing a multifunctional filter.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A multifunctional filter, comprising:

[0008] A valve seat is provided for connecting to a filter element. The valve seat has an inlet channel, an outlet channel, a drain channel, and a regulating chamber. The regulating chamber is located between the inlet channel, the outlet channel, and the drain channel.

[0009] A conversion assembly is rotatably disposed within the regulating cavity. The conversion assembly includes a conversion water passage communicating with the regulating cavity. The conversion assembly rotates relative to the valve seat within the regulating cavity, thereby driving the conversion water passage to rotate relative to the inlet channel, outlet channel, and sewage discharge channel.

[0010] As described above, in a multifunctional filter, the conversion assembly includes a first adjusting member rotatably disposed within the adjusting chamber and a second adjusting member connected to the first adjusting member. The conversion water passage is disposed between the first and second adjusting members. The conversion water passage includes a first opening and a first inner cavity connected in communication with the first adjusting member, and a second opening and a second inner cavity connected in communication with the second adjusting member. The first inner cavity is connected to the raw water end of the filter element through the adjusting chamber. The second adjusting member extends at least partially into the first inner cavity and is rotatably connected to the valve seat. The second opening is disposed away from the first opening and isolated from the first inner cavity. The second inner cavity is connected to the clean water end of the filter element, and the second opening is connected to the adjusting chamber.

[0011] As described above, the multifunctional filter further includes a water inlet channel located outside the first adjusting member. The water inlet channel communicates with the second opening and the adjusting cavity. A water-stop wall located on one side of the water inlet channel is also provided outside the first adjusting member. The water-stop wall and the water inlet channel are arranged circumferentially along the first adjusting member. The first opening is located between the water-stop wall and the water inlet channel.

[0012] As described above, in a multifunctional filter, the first adjusting member is further provided with a limiting boss located on the upper part of the water stop wall and the water inlet channel. The valve seat is provided with a first positioning block on the side of the water inlet channel and a second positioning block on the side of the water outlet channel. The limiting boss is rotatably abutted against the upper part of the first positioning block and the second positioning block. The switching water passage further includes a first water guide port located on the upper part of the water inlet channel and outside the first adjusting member. The first water guide port is located in the limiting boss and is opposite to the water inlet channel. The first water guide port is connected to the adjusting cavity and the water inlet channel.

[0013] In a multifunctional filter as described above, the second opening is higher than the water inlet tank.

[0014] As described above, in a multifunctional filter, the conversion assembly further includes a first drive member connected to the second adjustment member. The first drive member is rotatably connected to the top of the valve seat. The first drive member drives the second adjustment member to rotate relative to the valve seat within the adjustment chamber, and the second adjustment member drives the first adjustment member to rotate synchronously within the adjustment chamber.

[0015] The multifunctional filter described above further includes an exhaust assembly connected to the conversion assembly. The exhaust assembly includes a second driving member and a third adjusting member connected to the second driving member. The second adjusting member also has an exhaust chamber located on the upper side of the second inner cavity and a connecting portion located between the second inner cavity and the exhaust chamber. The connecting portion has a communication port communicating with the exhaust chamber and the second inner cavity. The third adjusting member is slidably disposed in the communication port. The second driving member drives the third adjusting member to slide relative to the communication port, so that the communication port is opened or closed, thereby controlling the connection between the second inner cavity and the exhaust chamber.

[0016] As described above, in a multifunctional filter, the exhaust assembly further includes a reset member disposed within the exhaust chamber, the reset member being sleeved on the outside of the third adjusting member and abutting between the second driving member and the connecting portion.

[0017] As described above, a multifunctional filter has an assembly portion at the bottom of the valve seat for connecting a second adjusting member and a filter element, and a second water guide port located outside the assembly portion. The assembly portion extends at least partially into the first inner cavity. The second adjusting member is rotatably disposed inside the assembly portion. The assembly portion has a third inner cavity, and the second inner cavity communicates with the clean water end of the filter element through the third inner cavity. Several second water guide ports are provided and are evenly distributed along the circumference of the bottom of the valve seat.

[0018] The multifunctional filter described above also includes an indicator plate connected to the valve seat. The top of the indicator plate is provided with a plurality of working status indicators, which are spaced apart around the circumference of the indicator plate. The conversion component is provided with a directional indicator on its exterior. The conversion component rotates relative to the valve seat, thereby causing the directional indicator to rotate synchronously to point to different working status indicators.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The multifunctional filter provided by this utility model includes a valve seat and a switching component. The valve seat is used to connect with the filter element. The valve seat is provided with an inlet channel, an outlet channel, a sewage discharge channel, and a regulating chamber. The regulating chamber is located between the inlet channel, the outlet channel, and the sewage discharge channel. The switching component is rotatably disposed in the regulating chamber. The switching component includes a switching water passage communicating with the regulating chamber. By rotating the switching component relative to the valve seat in the regulating chamber, the switching water passage is driven to rotate relative to the inlet channel, the outlet channel, and the sewage discharge channel, thereby controlling the on / off connection between the switching water passage and the inlet channel, the outlet channel, the sewage discharge channel, and the filter element, realizing the switching of different working water passages in the filter. By setting a rotatable switching component between the inlet channel, the outlet channel, and the sewage discharge channel, the user can directly rotate the switching component to switch the on / off connection between different channels, thereby realizing the switching of multiple working water passages, which is beneficial to enhancing the functionality of the filter and is simple to operate.

[0021] 2. By setting the inlet, outlet, and sewage channels in the valve seat, it is beneficial to centrally install the conversion components, simplify the filter structure, and improve the convenience of filter connection pipelines, making it easier for users to install the filter.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0039] like Figure 1 As shown in Figure 13, this utility model provides a multifunctional filter, wherein... Figure 5 and Figure 6 A schematic diagram of the water circuit in the filtration process. Figures 7 to 9 A water circuit diagram showing the filter cartridge flushing status. Figure 10 This is a schematic diagram of a waterway in bypass mode. Figure 11 A schematic diagram of the waterway in a stopped state.

[0040] The filter includes a valve seat 1 and a switching assembly 22. The valve seat 1 is used to connect with the filter element 5. The valve seat 1 has an inlet channel 11, an outlet channel 12, a sewage discharge channel 13, and a regulating chamber 14. The regulating chamber 14 is located between the inlet channel 11, the outlet channel 12, and the sewage discharge channel 13. The switching assembly 22 is rotatably disposed in the regulating chamber 14. The switching assembly 22 includes a switching water passage communicating with the regulating chamber 14. By rotating the switching assembly 22 relative to the valve seat 1 within the regulating chamber 14, the switching water passage is driven to rotate relative to the inlet channel 11, the outlet channel 12, and the sewage discharge channel 13, thereby controlling the switching water passage relative to the inlet channel 11. The switching between different working water paths in the filter is achieved by opening and closing the water outlet channel 12, the sewage discharge channel 13, and the filter element 5. This multifunctional filter of the present invention, by setting a rotatable switching component 22 between the water inlet channel 11, the water outlet channel 12, and the sewage discharge channel 13, allows the user to directly rotate the switching component 22 to switch between different channels, thereby realizing the switching of multiple working water paths, which is beneficial to enhancing the functionality of the filter and is easy to operate. In addition, by setting the water inlet channel 11, the water outlet channel 12, and the sewage discharge channel 13 in the valve seat 1, it is beneficial to centrally set the switching component 22, simplify the structure of the filter, and also improve the convenience of connecting the filter pipeline, making it convenient for users to install the filter.

[0041] In this embodiment, the filter has at least a filtration state, a filter element flushing state, and a bypass state. Specifically, when the conversion component 22 rotates to the point where the conversion water passage connects with the inlet channel 11, the filter element 5, and the outlet channel 12, the filter switches to the filtration state. At this time, the sewage discharge channel 13 is blocked by the conversion component 22. The inlet channel 11 is connected to the raw water end 51 of the filter element 5 through the conversion water passage, and the clean water end 52 of the filter element 5 is connected to the outlet channel 12 through the conversion water passage. Raw water can be input into the filter element 5 for filtration through the inlet channel 11. The filtered water can flow to the outlet channel 12 and be output, thereby realizing the filtration function of the filter; when the conversion component 22 rotates to connect the conversion water passage with the inlet channel 11, the filter element 5, and the sewage discharge channel 13, the filter switches to the filter element flushing state. At this time, the outlet channel 12 is blocked by the conversion component 22, the inlet channel 11 is connected to the filter element 5 through the conversion water passage, and the filter element 5 is connected to the sewage discharge channel 13 through the conversion water passage. Raw water can be input into the filter element 5 through the inlet channel 11 for flushing, and the concentrated water formed after flushing can be discharged through the sewage discharge channel 13. This enables the filter element to be flushed, which is beneficial for cleaning the filter element and improving the filtration performance of the filter element 5. Optionally, the filter element flushing can be performed by forward flushing or backwashing. If the filter uses forward flushing, the inlet channel 11 is connected to the raw water end 51 of the filter element 5 through a switching water path, and the clean water end 52 of the filter element 5 is connected to the sewage discharge channel 13 through a switching water path. If the filter uses backwashing, the inlet channel 11 is connected to the clean water end 52 of the filter element 5 through a switching water path, and the raw water end 51 of the filter element 5 is connected to the sewage discharge channel 13 through a switching water path. This embodiment does not specify... Specifically, when the conversion component 22 rotates to connect the conversion water passage with the inlet channel 11 and the outlet channel 12, the filter switches to a bypass state. At this time, the sewage discharge channel 13 and the filter element 5 are blocked by the conversion component 22. Raw water can enter the conversion water passage through the inlet channel 11 and flow to the outlet channel 12 for output. In practical applications, when the filter element 5 becomes clogged and fails, the filter can switch to the bypass state to ensure the normal flow of water in the filter. At the same time, users can directly disassemble and replace the new filter element 5, improving the convenience of water use for users.

[0042] In other alternative embodiments, such as Figure 4As shown, the inlet channel 11, outlet channel 12, and sewage discharge channel 13 are distributed circumferentially around the valve seat 1, which simplifies the water path layout in the switching assembly 22. The switching assembly 22 can rotate relative to the inlet channel 11, outlet channel 12, and sewage discharge channel 13 within the regulating chamber 14 under force, thus directly switching between different water paths. The inlet channel 11 and outlet channel 12 are symmetrically arranged on both sides of the valve seat 1, and the sewage discharge channel 13 is located between the inlet channel 11 and outlet channel 12, so that the inlet channel 11 and outlet channel 12 can be on the same straight line, which helps to shorten the water path length between the inlet channel 11 and outlet channel 12 and improve the water conveyance efficiency of the filter.

[0043] Specifically, such as Figures 1 to 13 As shown, the conversion assembly 22 includes a first adjusting member 21 rotatably disposed within the adjusting cavity 14 and a second adjusting member 22 connected to the first adjusting member 21. The first adjusting member 21 and the second adjusting member 22 are fixedly connected. The conversion water passage is disposed between the first adjusting member 21 and the second adjusting member 22. The conversion water passage includes a first opening 201 and a first inner cavity 202 connected in communication with the first adjusting member 21, and a second opening 203 and a second inner cavity 204 connected in communication with the second adjusting member 22. The first opening 201 corresponds to the circumferential surface of the inlet channel 11, the outlet channel 12, and the sewage discharge channel 13. The first inner cavity 202 is connected to the raw water end 51 of the filter element 5 through the adjusting cavity 14. The second adjusting member 22 extends at least partially into the first inner cavity 202 and is rotatably connected to the valve seat 1. The second opening 203 is located away from the first opening 201 and isolated from the first inner cavity 202. The second inner cavity 204 is connected to the purified water end 52 of the filter element 5. The second opening 203 is connected to the adjusting cavity 14, and after assembly, the second opening 203 is separated from the first inner cavity 202. In this embodiment, the second adjusting member 22 can rotate within the adjusting cavity 14 under force, and drive the first adjusting member 21 to rotate synchronously. During this process, the first adjusting member 21 drives the first opening 201 to rotate, and the second adjusting member 22 drives the second opening 203 to rotate. Figure 5 and Figure 6As shown, when the first opening 201 rotates to face the inlet channel 11 and the second opening 203 rotates to face the outlet channel 12, the filter switches to the filtration state. At this time, the inlet channel 11, the first opening 201, the first inner cavity 202, the regulating cavity 14, and the raw water end 51 of the filter element 5 are connected, so that the valve seat 1 can input raw water to the filter element 5 through the switching water path. The clean water end 52, the second inner cavity 204, the second opening 203, and the regulating cavity 14 of the filter element 5 are connected to the outlet channel 12, so that the filter element 5 can output clean water to the valve seat 1 through the switching water path. This forms the working water path of the filter in the filtration state, and the filter can normally use the filter element 5 to perform filtration and water purification. In addition, the sewage discharge channel 13 is closed by the outer wall of the first regulating member 21 to separate it from the regulating cavity 14, so as to prevent water from being lost through the sewage discharge channel 13, thereby increasing the clean water output of the filter.

[0044] Furthermore, such as Figure 3 As shown, the conversion water passage also includes a water inlet trough 205 disposed outside the first adjusting member 21. The water inlet trough 205 communicates with the second opening 203 and the adjusting cavity 14. A water-stop wall 211 located on one side of the water inlet trough 205 is also provided outside the first adjusting member 21. The water-stop wall 211 and the water inlet trough 205 are arranged circumferentially along the first adjusting member 21. The first opening 201 is disposed between the water-stop wall 211 and the water inlet trough 205. In this embodiment, a portion of the outer wall of the first adjusting member 21 is recessed inward to form the water inlet trough 205, and the water inlet trough 205 extends circumferentially along the first adjusting member 21. Another portion of the outer wall of the first adjusting member 21 forms the water-stop wall 211, and the water inlet trough 205 and the water-stop wall 211 are located in the same circle within the first adjusting member 21. The first opening 201 is radially disposed at one end of the water-stop wall 211 along the first adjusting member 21, and the first opening 201 is close to the water inlet channel 205. The periphery of the first opening 201 is separated from the water inlet channel 205 by the water-stop wall 211. The first adjusting member 21 rotates within the adjusting cavity 14 relative to the water inlet channel 11, water outlet channel 12 and sewage discharge channel 13 to adjust the positional relationship between the first opening 201, water inlet channel 205 and water-stop wall 211 and the water inlet channel 11, water outlet channel 12 and sewage discharge channel 13, thereby connecting different water paths and realizing multiple functions of the filter such as filtration, filter element rinsing, bypassing and water stop, which is beneficial to enhancing the functionality of the filter. Moreover, the user can switch between different water paths by directly rotating the conversion component 22, which is simple to operate.

[0045] In this embodiment, the circumferential surfaces of the waterstop wall 211, the water inlet channel 205, and the first opening 201 are opposite to the circumferential surfaces of the inlet channel 11, the outlet channel 12, and the sewage discharge channel 13; in practical applications, such as Figure 5 and Figure 6 As shown, when the filter is in the filtration state, the first opening 201 is directly connected to the inlet channel 11, and the second opening 203 is connected to the outlet channel 12 through the regulating chamber 14. At this time, raw water can be sequentially input into the raw water end 51 of the filter element 5 through the inlet channel 11, the first opening 201, the first inner cavity 202, and the regulating chamber 14, and filtered by the filter element 5. The purified water formed by the filter element 5 can be output through its purified water end 52 into the second inner cavity 204, and sequentially output through the second inner cavity 204, the second opening 203, the regulating chamber 14, and the outlet channel 12. At the same time, the water-stop wall 211 is opposite to the inlet end of the sewage discharge channel 13, and the sewage discharge channel 13 is sealed by the water-stop wall 211 to prevent water from flowing out through the sewage discharge channel 13, thereby increasing the purified water output of the filter; Figures 7 to 9 As shown, when the filter is in the filter element flushing state, the water inlet trough 205 rotates to face the water inlet channel 11, and the first opening 201 rotates to face the sewage discharge channel 13. At this time, the water inlet channel 11 is connected to the clean water end 52 of the filter element 5 through the water inlet trough 205 and the second opening 203, and the raw water end 51 of the filter element is connected to the sewage discharge channel 13 through the regulating chamber 14, the first inner chamber 202 and the first opening 201. The raw water can sequentially pass through the water inlet channel 11, the water inlet trough 205, and the second opening 201. 3. The second inner cavity 204 is fed into the filter element 5, and flows from the clean water end 52 of the filter element 5 to the raw water end 51 to achieve backwashing of the filter element. The concentrated water formed by backwashing flows sequentially through the regulating cavity 14, the first inner cavity 202 and the first opening 201 to the sewage discharge channel 13 and is output. At the same time, the water-stop wall 211 rotates to be opposite to the water inlet end of the outlet channel 12, and closes the outlet channel 12 through the water-stop wall 211 to prevent concentrated water from being output through the outlet channel 12, prevent users from accidentally using concentrated water, and help improve the backwashing efficiency of the filter element; Figure 10As shown, when the filter is in bypass mode, the water inlet trough 205 rotates to face the inlet channel 11 and outlet channel 12. At this time, raw water can flow directly through the inlet channel 11 and the water inlet trough 205 to the outlet channel 12 and be output. Simultaneously, the first opening 201 rotates to face the wall in the valve seat 1 located between the inlet channel 11 and the drain channel 13, and the first opening 201 is blocked by the water-stop wall 211, preventing the first opening 201 from communicating with the inlet channel 11, thereby preventing raw water from entering the filter element 5. When the filter element 5 becomes clogged and fails, the filter can be adjusted to bypass mode to ensure normal water flow, thus guaranteeing the user's water supply. The user can also directly replace the filter element 5. In this embodiment, as... Figure 11 As shown, the filter also has a water-stop state, that is, the water-stop wall 211 rotates to be opposite to the water inlet channel 11, and blocks the raw water from entering the regulating chamber 14 and the conversion water path through the water-stop wall 211, thereby stopping the filter from flowing water.

[0046] In other alternative embodiments, to improve the rotational stability of the first adjusting member 21 and the second adjusting member 22, such as Figure 3As shown, the first adjusting member 21 is further provided with a limiting boss 212 located on the upper part of the waterstop wall 211 and the water inlet channel 205. The valve seat 1 is provided with a first positioning block 15 on one side of the water inlet channel 11 and a second positioning block 16 on one side of the water outlet channel 12. The limiting boss 212 rotatably abuts against the upper part of the first positioning block 15 and the second positioning block 16. The first positioning block 15 is fixedly set at the water outlet end of the water inlet channel 11, and the second positioning block 16 is fixedly set at the water inlet end of the water outlet channel 12. The first adjusting member 21 rotatably abuts against the upper part of the first positioning block 15 and the second positioning block 16 through the limiting boss 212, so as to reduce the rotation contact surface of the first adjusting member 21, thereby improving the rotational smoothness of the first adjusting member 21, so that the conversion component 22 can rotate smoothly. The first adjusting member 21 can be supported by the first positioning block 15 and the second positioning block 16, thereby improving the stability of the first adjusting member 21. Furthermore, in order to ensure the smooth flow of the switching water path, the switching water path also includes a first water guide port 206 located outside the first adjusting member 21 and above the water inlet trough 205. The first water guide port 206 is located in the limiting boss 212 and is opposite to the water inlet trough 205. The first water guide port 206 is connected to the adjusting cavity 14 and the water inlet trough 205. The first water guide port 206 connects the water inlet trough 205 and the second opening 203 to ensure that the backwash water path in the switching water path can be connected, thereby ensuring the normal use of the filter element flushing function. Further, optionally, there are several first water guide ports 206, which is beneficial to improving the water conveying efficiency in the first adjusting member 21.

[0047] In other alternative embodiments, such as Figure 1 and Figure 2 As shown, the first adjusting member 21 is further provided with a first engaging portion 213 located on the upper part of the limiting boss 212, and the second adjusting member 22 is provided with a second engaging portion 224 corresponding to the first engaging portion 213. The first engaging portion 213 and the second engaging portion 224 are engaged to achieve a fixed connection between the first adjusting member 21 and the second adjusting member 22. Optionally, in the first engaging portion 213 and the second engaging portion 224, one engaging portion is configured as a locking block and the other engaging portion is configured as a locking groove adapted to the locking block, so as to facilitate the assembly and disassembly of the first adjusting member 21 and the second adjusting member 22. Furthermore, the second opening 203 is provided on one side of the second engaging portion 224 along the circumference of the second adjusting member 22, so as to improve the structural compactness of the second adjusting member 22 and thereby reduce the volume of the second adjusting member 22.

[0048] In other alternative embodiments, such as Figure 6As shown, the second opening 203 is higher than the water inlet trough 205; after assembly, the second opening 203 is higher than the water inlet end of the water outlet channel 12. When the filter is in the filtration state, the purified water formed by the filter element 5 is output from the purified water end 52 of the filter element 5 to the second inner cavity 204, and the purified water flows sequentially through the second inner cavity 204, the second opening 203, and the regulating cavity 14 to the water outlet channel 12 and is output. By setting the second opening 203 on the upper side of the water inlet end of the water outlet channel 12, it is beneficial to increase the water flow speed by using gravity, thereby improving the output efficiency of purified water.

[0049] On the other hand, in some alternative embodiments, the present invention also provides a driving method for the conversion component 22, such as... Figure 6 As shown, the conversion assembly 22 further includes a first driving member 23 connected to the second adjusting member 22. The first driving member 23 is rotatably connected to the top of the valve seat 1. The first driving member 23 drives the second adjusting member 22 to rotate relative to the valve seat 1 within the adjustment cavity 14, and the second adjusting member 22 drives the first adjusting member 21 to rotate synchronously within the adjustment cavity 14. In practical applications, the user can directly rotate the first driving member 23 to drive the first adjusting member 21 and the second adjusting member 22 to rotate synchronously relative to the valve seat 1 within the adjustment cavity 14, thereby switching different working water paths in the filter and switching different working states of the filter, which is convenient for user operation. It should be noted that the user can rotate the first driving member 23 clockwise or counterclockwise to drive the first adjusting member 21 and the second adjusting member 22 to rotate. This utility model does not make specific limitations, as long as it can achieve the filtration, filter element flushing, bypass and water stop states of the filter described above.

[0050] On the other hand, in some alternative embodiments, in order to maintain stable internal pressure of the filter, the filter of this invention is also provided with an exhaust assembly 3, such as... Figure 12 and Figure 13As shown, the filter also includes an exhaust assembly 3 connected to the conversion component 22. The exhaust assembly 3 includes a second drive member 31 and a third adjustment member 32 connected to the second drive member 31. The second adjustment member 22 also has an exhaust chamber 221 located on the upper side of the second inner cavity 204 and a connecting portion 222 located between the second inner cavity 204 and the exhaust chamber 221. The connecting portion 222 has a communication port 223 communicating with the exhaust chamber 221 and the second inner cavity 204. The third adjustment member 32 is slidably disposed in the communication port 223. The second drive member 31 drives the third adjustment member 32 to slide relative to the communication port 223, so that the communication port 223 opens or closes, thereby controlling the connection between the second inner cavity 204 and the exhaust chamber 221. The user can exhaust the filter through the exhaust assembly 3, which can prevent air accumulation inside the filter, maintain stable internal pressure, prevent residual air bubbles inside the filter element 5, and improve filtration efficiency. In this embodiment... The second driving member 31 is slidably disposed on the top of the valve seat 1, that is, the second driving member 31 can be configured as a pressing member. The third adjusting member 32 can be configured as a valve stem with a cap, which is slidably disposed through the communication port 223, and the cap portion of the valve stem is located in the second inner cavity 204. The stem body portion extends into the exhaust cavity 221 and is fixedly connected to the second driving member 31. In practical applications, the user can directly press the second driving member 31 to drive the third adjusting member 32. The sliding of the connecting port 223 causes it to open or close. Specifically, when the third adjusting member 32 moves downward relative to the connecting port 223, the connecting port 223 opens, allowing the exhaust chamber 221 and the second inner cavity 204 to communicate, and the gas can be discharged through the assembly gap between the second driving member 31 and the inner wall of the exhaust chamber 221. When the third adjusting member 32 moves upward relative to the connecting port 223, the connecting port 223 closes, separating the exhaust chamber 221 and the second inner cavity 204.

[0051] Furthermore, in order to improve the reset efficiency of the exhaust assembly 3 and further enhance the convenience of the user's exhaust operation, such as... Figure 13As shown, the exhaust assembly 3 further includes a reset member 33 disposed within the exhaust chamber 221. The reset member 33 is sleeved on the outside of the third adjusting member 32 and abuts against the second driving member 31 and the connecting portion 222. Optionally, the reset member 33 can be configured as an elastic element such as a spring, which is not specifically limited in this utility model. In practical applications, when the third adjusting member 32 moves downward relative to the connecting port 223 via the second driving member 31, the reset member 33 is simultaneously pressed by the second driving member 31, so that the reset member 33 generates elastic energy. When the user cancels the force applied to the second driving member 31, the elastic force of the reset member 33 can react on the second driving member 31 to drive the second driving member 31 upward, thereby realizing the automatic reset of the second driving member 31.

[0052] In some alternative embodiments, the second drive member 31 is slidably disposed inside the first drive member 23, and the first drive member 23 is provided with a mounting cavity 231 that can accommodate the second drive member 31, so as to simplify the structure of the valve seat 1, make the filter structure more compact and small, and reduce the volume of the filter.

[0053] On the other hand, in some alternative embodiments, such as Figure 6 As shown, the valve seat 1 has an assembly part 17 at its bottom for connecting the second adjusting member 22 and the filter element 5, and a second water guide 18 located outside the assembly part 17. The assembly part 17 extends at least partially into the first inner cavity 202. The second adjusting member 22 is rotatably disposed inside the assembly part 17. The assembly part 17 has a third inner cavity 171. The second inner cavity 204 communicates with the clean water end 52 of the filter element 5 through the third inner cavity 171. Several second water guides 18 are provided and are evenly distributed along the circumference of the bottom of the valve seat 1. In this embodiment, the bottom of the assembly part 17 extends outside the valve seat 1, and the filter element 5 can be engaged with the bottom of the assembly part 17. The top of the assembly part 17 extends into the first inner cavity 202. The component 22 can be snapped into the top of the assembly part 17, which is simple in structure and convenient for users to disassemble and assemble the filter element 5. The assembly part 17 has a third inner cavity 171 along the axial direction. The third inner cavity 171 connects the second inner cavity 204 and the clean water end 52 of the filter element 5. It is also sealed to the assembly part 17 through the second adjusting component 22 to isolate the first inner cavity 202 and the second inner cavity 204, thereby avoiding the confusion of the water path inside the first adjusting component 21 and the second adjusting component 22. In addition, the bottom periphery of the valve seat 1 is provided with a number of second water guide ports 18. The first inner cavity is connected to the raw water end of the filter element through the adjusting cavity and the second water guide ports, which is conducive to the uniform delivery of water flow between the filter element and the valve seat and improves the water delivery efficiency between the filter element and the valve seat.

[0054] On the other hand, in some alternative embodiments, to further facilitate user operation of the conversion component 2, such as... Figure 4 As shown, the filter also includes an indicator plate 4 connected to the valve seat. The top of the indicator plate 4 is provided with several operating status indicators 41, which are spaced circumferentially around the indicator plate 4. The conversion component 2 has directional indicators on its exterior. Rotation of the conversion component 2 relative to the valve seat causes the directional indicators to rotate synchronously, pointing to different operating status indicators 41. In this embodiment, the several operating status indicators 41 include at least a filtration status indicator, a backwash status indicator, a bypass status indicator, and a stop status indicator. The filtration status indicators face the inlet water channel. The backwash status indicator faces the sewage discharge channel, the bypass status indicator is located between the filter status indicator and the backwash status indicator, and the stop status indicator is radially positioned relative to the backwash status indicator. The directional indicator is located outside the first drive component to facilitate direct observation by the user. In practical applications, when the user rotates the first drive component to drive the conversion component 2, the user can point to the filter status indicator, backwash status indicator, bypass status indicator, or stop status indicator according to the directional indicator to identify the driving status of different working water paths of the filter, thereby further facilitating the user's operation of the conversion component 2.

Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
