[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0021] Reference Figure 1-4 The first embodiment of this utility model provides a filter assembly 1 including a water inlet 101, a water heater 102 and a support plate 103. The water inlet 101 is located at the front end of the water heater 102. The lower end of the water heater 102 is fixedly connected to the upper end of the support plate 103. A cleaning mechanism 2 and a blocking mechanism 3 are provided inside the water inlet 101. The cleaning mechanism 2 is used to clean the filter plate 208, and the blocking mechanism 3 is used to assist the cleaning mechanism 2.

[0022] Specifically, the filter assembly 1 solves the problems of inconvenient maintenance and easy leakage during cleaning of the traditional water inlet filter device of water heater 102. By integrating the cleaning mechanism 2 and the blocking mechanism 3 into the water inlet 101 at the front end of water heater 102, the filter plate 208 can be quickly disassembled and automatically sealed during the cleaning process. The blocking mechanism 3 can actively close the water flow channel before cleaning, effectively preventing water from flowing into the water heater 102 when the filter plate 208 is disassembled, thus improving operational safety.

[0023] Furthermore, when it is necessary to filter the water entering the water heater 102, the water inlet 101 is located at the front end of the water heater 102, and a filter assembly 1 is integrated inside, including a filter screen, a cleaning mechanism 2 and a blocking mechanism 3. The filter screen is installed inside the water inlet 101, and the filter plate 208 is fixed in the water inlet channel by a limiting structure. When cleaning is required, the filter plate 208 can be cleaned by the cleaning mechanism 2. To prevent water from entering the water heater 102 during cleaning, the blocking mechanism 3 can assist the cleaning mechanism 2. Example

[0024] The second embodiment of this utility model provides a cleaning mechanism 2 including a limiting rod 201, a spring 202, a guide plate 203, a fixing rod 204, a connecting plate 205, a fixing shaft 206, a limiting block 207, and a filter plate 208. The limiting rod 201 is fitted with a spring 202, the upper end of which is fixedly connected to the lower end of the guide plate 203. The lower end of the guide plate 203 is fixedly connected to the upper end of the fixing rod 204, and the lower end of the fixing rod 204 is fixedly connected to the upper end of the connecting plate 205. The inner wall of the connecting plate 205 is flush with the surface of the fixing shaft 206. The connecting plate 205 is rotatably connected to the inner wall of the connecting plate 205 and the surface of the limiting block 207. The surface of the limiting block 207 contacts the upper inner wall of the filter plate 208. The surface of the filter plate 208 is movably connected to the inner wall of the inlet 101. The lower end of the fixed shaft 206 is fixedly connected to the surface of the inlet 101. The lower end of the spring 202 is fixedly connected to the upper end of the limiting block 207. The lower end of the limiting rod 201 is fixedly connected to the upper end of the limiting block 207. The surface of the limiting rod 201 is slidably connected to the inner wall of the guide plate 203. The upper end of the filter plate 208 contacts the lower end of the connecting plate 205.

[0025] Specifically, the cleaning mechanism 2 effectively solves the problem of impurities accumulating and being difficult to clean after long-term use of the filter screen. Through the cooperation of the limiting rod 201, spring 202 and limiting block 207, the filter plate 208 can be quickly locked and released. It can still maintain stable fixation under water pressure conditions to prevent loosening and leakage. The rotating connection structure between the connecting plate 205 and the fixed shaft 206 provides rotational clearance space for the disassembly of the filter plate 208, improving maintenance accessibility. The overall structure is easy to operate. The filter plate 208 can be removed without disassembling other parts, reducing maintenance difficulty and time costs, and ensuring the continuous and efficient operation of the filtration system.

[0026] Furthermore, to ensure that water must pass through the filter screen before entering the water heater 102, a connecting plate 205 is provided above the filter plate 208 for easy maintenance. This connecting plate 205 is connected to the surface of the water inlet 101 via a fixed shaft 206 and can rotate around the shaft, thus providing operating space for disassembling the filter plate 208. Under normal operating conditions, the limiting block 207 at the lower end of the limiting rod 201 is embedded in the limiting groove on the inner wall of the filter plate 208. Combined with the spring 202 structure on the limiting rod 201, this ensures that the filter plate 208 remains stable under water pressure, preventing loosening or displacement. When the filter screen accumulates impurities due to long-term use, affecting water flow efficiency and filtration performance, it needs to be cleaned and maintained. During operation, firstly, the operator pulls the limiting rod 201 upwards, compressing the spring 202 sleeved on its surface, causing the limiting block 207 to disengage from the limiting groove of the filter plate 208, releasing the axial constraint on the filter plate 208. At this time, the connecting plate 205 can be rotated around the fixed shaft 206 to move it away from the position directly above the filter plate 208, creating an unobstructed passage for removing the filter plate 208. After that, the filter screen can be removed as a whole for rinsing or replacement, thereby restoring the filtration function. Example

[0027] The third embodiment of this utility model provides a blocking mechanism 3 including a servo motor 301, an adjusting screw 302, a connecting block 303, a guide rod 304, a fixing block 305, a blocking plate 306, and a fixing plate 307. The output end of the servo motor 301 is fixedly connected to the surface of the adjusting screw 302. The surface of the adjusting screw 302 is rotatably connected to the inner wall of the connecting block 303. The lower end of the connecting block 303 is fixedly connected to the upper end of the guide rod 304. The surface of the guide rod 304 is slidably connected to the inner wall of the fixing block 305. The surface of the fixing block 305 is fixedly connected to the surface of the blocking plate 306. The lower end of the guide rod 304 is fixedly connected to the upper end of the fixing plate 307. The surface of the servo motor 301 is fixedly connected to the surface of the connecting block 303. The surface of the adjusting screw 302 is threadedly connected to the inner wall of the fixing block 305. The lower end of the adjusting screw 302 is rotatably connected to the surface of the fixing plate 307. The surface of the fixing plate 307 is fixedly connected to the surface of the water inlet 101. The surface of the blocking plate 306 is slidably connected to the inner wall of the water inlet 101.

[0028] Specifically, the blocking mechanism 3 effectively solves the problem that the water source cannot be completely cut off during the filter cleaning process, which can easily lead to water flowing into the water heater 102. The servo motor 301 drives the adjusting screw 302 to rotate, which drives the fixed block 305 and the blocking plate 306 to move smoothly along the guide rod 304, thereby achieving automatic sealing of the water inlet 101. The blocking plate 306 slides and seals with the inner wall of the water inlet 101 to ensure no leakage when closed, thus ensuring the reliability and convenience of the maintenance process.

[0029] Furthermore, to ensure that no water enters the water heater 102 during the removal and cleaning of the filter plate 208, the system is equipped with an automatic sealing blocking mechanism 3. This mechanism is driven by a servo motor 301, with the motor output end connected to an adjusting screw 302. The adjusting screw 302 is threadedly engaged with a connecting block 303 and linked to a fixed rod 204 through the connecting block 303, thereby driving the fixed blocks 305, which have blocking plates 306 fixed at both ends, to move synchronously. The adjusting screw 302 and the guide rod 304 are set in parallel. The fixed blocks 305 are threadedly connected to the adjusting screw 302 and slidably engaged with the guide rod 304 to ensure smooth movement. When the servo motor 301 is started, the adjusting screw 302 rotates, pushing the fixed blocks 305 to move axially, thereby driving the blocking plates 306 to move towards the center of the inlet 101 until their sealing surfaces are tightly fitted against the inner wall of the inlet 101, achieving complete sealing of the water flow channel.

[0030] When filtration of the water entering the water heater 102 is required, the inlet 101 is located at the front end of the water heater 102 and integrates a filter assembly 1, including a filter screen, a cleaning mechanism 2, and a blocking mechanism 3. The filter screen is installed inside the inlet 101, and the filter plate 208 is fixed in the water inlet channel by a limiting structure to ensure that the water flow must pass through the filter screen before entering the water heater 102. For easy maintenance, a connecting plate 205 is provided above the filter plate 208. The connecting plate 205 is connected to the surface of the inlet 101 through a fixed shaft 206 and can rotate around the shaft, thereby facilitating the disassembly of the filter plate 208. The limit rod 201 provides operating space. Under normal operating conditions, the limit block 207 at the lower end of the limit rod 201 is embedded in the limit groove on the inner wall of the filter plate 208. This, along with the spring 202 on the limit rod 201, ensures the filter plate 208 remains stable under water pressure, preventing loosening or displacement. When impurities accumulate on the filter screen due to long-term use, affecting water flow efficiency and filtration performance, cleaning and maintenance are required. During operation, the operator first pulls the limit rod 201 upwards, compressing the spring 202 on its surface, causing the limit block 207 to disengage from the limit groove of the filter plate 208, thus releasing the pressure on the filter plate 208. With the axial constraint removed, the connecting plate 205 can be rotated around the fixed shaft 206 to move it away from the position directly above the filter plate 208, creating an unobstructed channel for removing the filter plate 208. Afterward, the entire filter screen can be removed for rinsing or replacement, thus restoring the filtration function. To ensure that no water enters the water heater 102 during the removal and cleaning of the filter plate 208, the system is equipped with an automatic sealing blocking mechanism 3. This mechanism is driven by a servo motor 301, with the motor output connected to an adjusting screw 302. The adjusting screw 302 is threadedly engaged with the connecting block 303, and the mechanism is connected to the connecting block... 303 is linked with the fixed rod 204, which drives the fixed block 305, which has the baffle plate 306 fixed at both ends, to move synchronously. The adjusting screw 302 and the guide rod 304 are set in parallel. The fixed block 305 is threadedly connected to the adjusting screw 302 and slidably engaged with the guide rod 304 to ensure smooth movement. When the servo motor 301 is started, the adjusting screw 302 rotates, pushing the fixed block 305 to move axially, which in turn drives the baffle plate 306 to move towards the center of the inlet 101 until its sealing surface is tightly fitted with the inner wall of the inlet 101, thus completely blocking the water flow channel.

[0031] In summary: the mechanical limiting and disassembly structure of the limiting rod, spring, connecting plate, and filter plate enables rapid unlocking and safe disassembly of the filter plate; the coordinated action of the automatic sealing mechanism composed of servo motor, adjusting screw, guide rod, fixing block, and blocking plate achieves dynamic sealing of the inlet during filter cleaning; overall, the orderly linkage between the cleaning mechanism and the blocking mechanism ensures safe maintenance and continuous sealing protection of the water heater inlet filtration system, effectively improving the maintainability and operational reliability of the filtration system.
