Since during the flushing process of the device, some flocculent foreign matters or water scales are easy to accumulate inside the filter cartridge and are not easy to be effectively flushed away, which will continue to affect the filtering effect and performance of the equipment.

[0006] Therefore, there is an urgent need for a reverse flushing type purifier filter cartridge to solve the above problems. Summary of the Utility Model

[0007] The object of the present utility model is to address the problem that it is currently inconvenient to thoroughly flush the interior of the device. During the use of the device, most of the water flow enters the interior of the device through the unobstructed areas on the surface of the filter cartridge, which easily leads to a low flushing intensity in some areas, making it impossible to effectively remove the impurities intercepted on the filter media in these areas and reducing the cleaning effect of the device.

[0008] In order to achieve the above-mentioned invention object, the present utility model provides the following technical solutions:

[0015] Through the above technical solution, a set of connecting shafts is driven to rotate by the connecting seat, causing the two baffles to unfold. At the same time, high-pressure water flows out from the diversion groove to scour the interior of the filter cartridge, ensuring the flushing effect.

[0016] As a preferred technical solution of the present application, the adjacent two groups of semi-gears are meshed with each other, and the connecting shafts are symmetrically distributed on the vertical center line of the positioning frame.

[0017] Through the above technical solution, the rotational force of a single set of connecting shafts is transmitted through the meshing of the adjacent two groups of semi-gears, causing the two connecting shafts to rotate in opposite directions simultaneously.

[0018] As a preferred technical solution of the present application, a number of inclined plates are arranged inside the baffle, and the number of inclined plates is equally spaced inside the baffle.

[0019] Through the above technical solution, the water flow is guided by the inclined plates, causing the water flow to scour in a spiral shape, generating a shearing and sweeping effect on the solid-phase particle impurities adhering to the surface of the filter cartridge.

[0020] As a preferred technical solution of the present application, the cleaning structure includes a chassis installed inside the water inlet, a rotating shaft rotatably connected to the top of the chassis, a fixing rod fixed to the outside of the rotating shaft, a guiding plate fixed to one side of the fixing rod, a support frame sleeved on the outside of the top of the rotating shaft, and a positioning block fixed to the top of the rotating shaft.

[0021] Through the above technical solution, the water flow is made to flow in a spiral shape through the guiding plate, so that the filter cartridge can better play its filtering role. During backwashing, the water flow scours the guiding plate to push the rotating shaft to rotate, so that the rotating guiding plate scrapes off foreign matters on the inner wall of the filter cartridge.

[0022] As a preferred technical solution of the present application, the rotating shaft passes through the support frame and is connected to the positioning block, and the rotating shaft is located on the vertical center line inside the filter cartridge.

[0023] Through the above technical solution, the support frame supports and limits the rotating shaft, so that the rotating shaft is not easily tilted or shaken.

[0024] Compared with the prior art, the beneficial effects of the present utility model are:

[0025] In the solution of the present application:

[0026] The connecting seat drives a group of connecting shafts to rotate, so that the two groups of baffles are unfolded. At the same time, high-pressure water flows out from the diversion grooves to scour the inside of the filter cartridge, ensuring the flushing effect. Thus, the high-efficiency flushing function of this device is realized, increasing the pressure and flow rate of the water flow entering the device, and at the same time guiding the water flow, so that the water flow flushes the inside of the filter cartridge violently, improving the cleaning effect of the filter cartridge and enhancing the functionality of this device;

[0027] The water flow is made to flow in a spiral shape through the guiding plate, so that the filter cartridge can better play its filtering role.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0034] As Figures 1-4 shown, a reverse flushing type purifier filter cartridge proposed in this embodiment includes a water inlet 1, and further includes,

[0035] A filter cartridge 2, fixed at the top end of the water inlet 1, and a top shell 5 is installed at the top end of the filter cartridge 2;

[0036] A protective net 3, fixed at the middle position between the water inlet 1 and the top shell 5;

[0037] A guide structure 4, arranged at the bottom end of the top shell 5, wherein the guide structure 4 includes a positioning frame 403 fixed at the bottom end of the top shell 5, a filling block 404 fixed at one side of the positioning frame 403, a transmission component installed on both sides inside the positioning frame 403, a baffle 401 fixed at one side of the transmission component, a flow guide groove 402 opened inside the baffle 401, and an inclined plate 405 fixed inside the flow guide groove 402;

[0038] A cleaning structure 6, arranged inside the filter cartridge 2, for cleaning the inside of the filter cartridge 2 during the flushing process of the device.

[0039] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the transmission assembly includes a connecting shaft 406 rotatably connected to both sides inside the positioning frame 403 and connected to the baffle 401, a semi-gear 408 fixed to the outside of the connecting shaft 406, and a connecting seat 407 installed on one side of the connecting shaft 406. The adjacent two groups of semi-gears 408 are meshed with each other. The connecting shafts 406 are symmetrically distributed on the vertical center line of the positioning frame 403. A number of inclined plates 405 are arranged inside the baffle 401, and the number of inclined plates 405 is equally spaced inside the baffle 401. The device drives the connecting shaft 406 to rotate through the connecting seat 407. At the same time, the semi-gear 408 transmits the rotational force of a single group of connecting shafts 406 through the meshing of the teeth, so that the two connecting shafts 406 rotate in opposite directions at the same time. Then, the two connecting shafts 406 drive the baffle 401 to flip, so that the baffle 401 unfolds to block the water flow inside the top shell 5, so that the water flow can only be ejected from the diversion groove 402, increasing the pressure and flow rate of the ejected water flow, ensuring the flushing effect. After the flushing is completed, the connecting seat 407 is rotated in the reverse direction to place the baffle 401 vertically, restricting the position of the positioning block 601.

[0040] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the cleaning structure 6 includes a bottom frame 605 installed inside the water inlet 1, a rotating shaft 603 rotatably connected to the top end of the bottom frame 605, a fixing rod 606 fixed to the outside of the rotating shaft 603, a diversion plate 604 fixed to one side of the fixing rod 606, a support frame 602 sleeved on the outside of the top end of the rotating shaft 603, and a positioning block 601 fixed to the top end of the rotating shaft 603. The rotating shaft 603 passes through the support frame 602 and is connected to the positioning block 601. The rotating shaft 603 is located on the vertical center line inside the filter cartridge 2. When the filter cartridge 2 is in normal use, the baffle 401 restricts the position of the positioning block 601, so that the rotating shaft 603 is fixed inside the filter cartridge 2. The water flow is guided by the diversion plate 604, so that the water flow flows in a spiral shape, improving the flow field on the surface of the filter cartridge 2, enabling the filter cartridge 2 to better play its filtering role, and improving the utilization rate and processing capacity of the filter cartridge 2. During backwashing, the positioning block 601 is unfolded, so that the rotating shaft 603 can rotate inside the support frame 602. The water flow flushes the diversion plate 604, pushing the rotating shaft 603 to rotate, so that the rotating diversion plate 604 scrapes the foreign matters on the inner wall of the filter cartridge 2, ensuring the cleaning effect.

[0041] Specifically, when the reverse flushing purifier filter cartridge is in use: by installing the device inside the purifier, the water flow is introduced into the interior of the filter cartridge 2 through the water inlet 1, and the water passes through the filter cartridge 2 for filtration. At the same time, the cleaning structure 6 is activated, causing the water flow to enter the interior of the filter cartridge 2 in a spiral shape, so that the impurities in the water flow are more evenly distributed inside the filter cartridge 2, thereby improving the filtration efficiency. During backwashing, by increasing the water pressure outside the filter cartridge 2, the water flow passes through and enters the interior of the filter cartridge 2, flushing the silt and foreign matters in the internal gaps of the filter cartridge 2. The top shell 5 is connected to the pipeline, allowing the water flow to be directly introduced into the interior of the filter cartridge 2. At the same time, the guiding structure 4 restricts the water flow, increasing the pressure and flow rate of the water flow entering the device, and guiding the water flow at the same time, so that the water flow violently flushes the interior of the filter cartridge 2.

[0042] During backwashing, the device drives the connecting shaft 406 to rotate through the connecting seat 407. At the same time, the semi-gear 408 transmits the rotational force of the single-group connecting shaft 406 through the engagement of the teeth, causing the two groups of connecting shafts 406 to rotate in opposite directions simultaneously. Immediately afterwards, the two groups of connecting shafts 406 drive the baffle 401 to flip, so that the baffle 401 unfolds to block the water flow inside the top shell 5, allowing the water flow to only spray out from the diversion groove 402, increasing the pressure and flow rate of the sprayed water flow, and ensuring the flushing effect. After the flushing is completed, the connecting seat 407 is rotated in the reverse direction, causing the baffle 401 to be placed vertically, restricting the position of the positioning block 601.

[0043] When the filter cartridge 2 is in normal use, the baffle 401 restricts the position of the positioning block 601, fixing the rotating shaft 603 inside the filter cartridge 2. The water flow is guided through the guide plate 604, causing the water flow to flow in a spiral shape, improving the flow field on the surface of the filter cartridge 2, enabling the filter cartridge 2 to better play its filtering role, and increasing the utilization rate and processing capacity of the filter cartridge 2. During backwashing, the positioning block 601 is unfolded, allowing the rotating shaft 603 to rotate inside the support frame 602. The water flow flushes the guide plate 604, pushing the rotating shaft 603 to rotate, and the rotating guide plate 604 scrapes the foreign matters on the inner wall of the filter cartridge 2, ensuring the cleaning effect.

[0044] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
