[0030] Figure 5The front view after installation of a cleaning filter element and a water purifier filter element provided by an embodiment of the present utility model is shown. Detailed implementation manners

[0031] To more clearly illustrate the present utility model, the present utility model will be further described below in conjunction with embodiments and drawings. Similar components in the drawings are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present utility model.

[0032] As Figure 1 shown, the present utility model provides a cleaning filter element, including:

[0033] A filter element body 1;

[0034] The filter element body 1 includes a first channel 2 and a second channel 3 that are in communication with each other;

[0035] The first channel 2 is in communication with the raw water inlet on the water purifier;

[0036] The second channel 3 is in communication with the wastewater outlet on the water purifier.

[0037] Since scale in the water purifier is often located in the raw water channel and the wastewater channel, the present disclosure connects the raw water inlet and the wastewater outlet on the water purifier through the connected first channel 2 and second channel 3. Compared with the current empty shell filter element structure, the structure of the present disclosure is simpler, smaller in volume, and lower in production and manufacturing costs.

[0038] The water purifier in the present disclosure can be a tabletop water purifier or an under-counter water purifier. Any water purifier that can filter water and may have scale in the wastewater channel and the raw water channel of the water purifier can use the cleaning filter element of the present disclosure, and it is not limited here.

[0039] In a possible implementation manner, in this embodiment, considering that the user may need to flush the pure water channel in the water purifier at the same time when removing scale (for example, when the water purifier has not been used for a long time, the pure water channel will also become dirty or the water quality will change, so it is necessary to flush the raw water channel, the wastewater channel and the pure water channel of the water purifier at the same time); based on this, the filter element body 1 in the present disclosure further includes a third channel 4 that is in communication with the pure water outlet on the water purifier. The third channel 4 is in communication with the first channel 2 and the second channel 3 respectively.

[0040] To prevent water from flowing out of the pure water outlet of the water purifier or the pure water outlet of the water circuit board on the water purifier when the filter element body 1 is installed in the water purifier or on the water circuit board of the water purifier, the present disclosure additionally provides a third channel 4;

[0041] In addition, since a water circuit board structure often exists during the installation of the water purifier, the raw water inlet, the wastewater outlet, and the pure water outlet on the water circuit board need to be inserted into the corresponding channels of the filter element body 1 and fixed to the filter element body 1. Among them, the three-channel fixed on the water circuit board or the water purifier has a more stable structure compared to the two-channel fixed on the water circuit board or the water purifier.

[0042] In a specific embodiment, a cavity 11 is provided inside the filter element body 1, and the first channel 2, the second channel 3, and the third channel 4 are communicated through the cavity 11. The cavity 11 can buffer the water flowing in or out of each water port, avoiding the water flowing out between the water purifier and the filter element body 1 due to too fast water flow; on the other hand, the cavity 11 is convenient to process and the presence of the cavity 11 makes the overall filter element material less, which can reduce the production cost.

[0043] In a possible implementation manner, in this embodiment, since scale in the water purifier is often located in the raw water channel and the wastewater channel, especially during flushing, if the flushing is not sufficient, citric acid and scale will inevitably exist in the pure water channel of the water purifier. Therefore, to avoid this situation, simplify the operation during flushing, and reduce the flushing duration, some users may not want to flush the pure water channel; thus, the filter element body 1 further includes a third channel 4 communicated with the pure water outlet on the water purifier; the third channel 4 is not communicated with the first channel 2 or the second channel 3. In a specific embodiment, stop valves are respectively arranged at the channel openings of the third channel 4. When the pure water outlet of the water purifier or the pure water outlet of the water circuit board on the water purifier is inserted into the third channel 4, the stop valves can also block the third channel 4.

[0044] In this embodiment, the pure water channel is not communicated, but only the raw water channel and the pure water channel on the water purifier are communicated through the first channel 2 and the second channel 3. Compared with the structure of the raw water channel and the wastewater channel with the pure water channel communicated, the structure of the present disclosure is simpler, and the flushing process is more convenient, and the flushing duration can also be appropriately shortened.

[0045] In a specific embodiment, in this embodiment, a cavity 11 is provided inside the filter element body 1, and the first channel 2 is communicated with the second channel 3 through the cavity 11. The cavity 11 can buffer the water flowing in or out of each water port, avoiding the water flowing out between the water purifier and the filter element body 1 due to too fast water flow. On the other hand, the cavity 11 is convenient to process and the presence of the cavity 11 makes the overall filter element material less, which can reduce the production cost.

[0046] In a possible implementation manner, as Figure 2 shown, the cavity 11 includes a cavity 112 with one end open formed by the filter element body 1 and an end cover 111 detachably connected to the filter element body 1 and located at the opening. The end cover 111 is hermetically connected to the filter element body 1.

[0047] In the present disclosure, the detachable connection mode of the end cap 111 facilitates the user to drain the water in the cavity 11, which is convenient for cleaning each channel in the cavity 11.

[0048] In a specific embodiment, the end cap 111 is snap-connected to the opening of the cavity 112, and the end cap 111 is hermetically connected to the cavity 112.

[0049] Since there will be scale and citric acid in the cavity during the flushing of scale, the detachable connection mode of the end cap 111 facilitates the cleaning of the cavity 11 in the filter element body 1 after the flushing is completed, and the water in the cavity 11 of the filter element body 1 can be quickly drained by opening the end cap 111 after the flushing of the water purifier filter element is completed.

[0050] In a possible implementation manner, in this embodiment, the filter element body 1 can be directly installed on the water purifier. However, due to the limited space at the position where the original filter element 5 is installed in the water purifier, and the filter element body 1 in the present disclosure is usually shorter in processing than the filter element 5, the too short filter element body 1 causes the user to need to hold the filter element body 1 and reach deep into the position of the original filter element 5 to install the cleaning filter element on the water purifier, so the installation is difficult; therefore, in this embodiment, the filter element 5 of the water purifier is detachably installed on the filter element body 1; the filter element body 1 is detachably installed on the connection port of the water purifier for connecting the filter element 5. To extend the length of the cleaning filter element, the user can directly use the combined body of the installed filter element body 1 and the filter element 5 to install the cleaning filter element on the water purifier, and the installation of the cleaning filter element is more convenient.

[0051] It should be noted that the filter element 5 in the present disclosure refers to the original filter element for filtration connected to the water purifier.

[0052] In a preferred embodiment, the length of the filter element 5 is greater than the length of the cleaning filter element; to further extend the length of the filter element body 1, which is convenient for installing the filter element body 1 on the water purifier, and to avoid the situation that it is difficult for the user to reach into the position of the water purifier at the connection of the original filter element 5 due to the too short length of the filter element body 1.

[0053] In a specific embodiment, as Figure 3 shown, the filter element body 1 is detachably installed on the connection port of the water purifier for connecting the filter element 5. Specifically, the outer side surface of the filter element body 1 is provided with a first engaging convex block 12 that cooperates with the water purifier, and the filter element body 1 rotates relative to the water purifier so that the filter element body 1 is buckled or separated from the water purifier.

[0054] At the bottom of the water purifier where the original filter element 5 is accommodated, a water circuit board structure is usually provided. The first engaging protrusion 12 provided on the outer side of the filter element body 1 is engaged with the engaging groove on the inner side of the water circuit board, so as to fix the filter element body 1 on the water purifier through the water circuit board. In another specific embodiment, there is no water circuit board structure on the water purifier, and an engaging groove that cooperates with the first engaging protrusion 12 is provided on the water purifier to directly fix the filter element body 1 on the water purifier; in the present utility model, the filter element body 1 should have the same connection structure as the original filter element 5, so that the filter element body 1 can also be connected to the water purifier at the position where the original filter element 5 is accommodated. Therefore, the present disclosure can be more conveniently installed and disassembled from the water purifier.

[0055] In a preferred implementation manner, a snap mechanism 13 and a limiting mechanism 14 that cooperate with the filter element 5 of the water purifier are provided on the filter element body 1. In addition to using the snap mechanism 13 and the limiting mechanism 14 for connection, the present disclosure can also connect the filter element 5 of the water purifier and the filter element body 1 in a threaded manner or the like. And in the present disclosure, direct plugging can be used for installation or disassembly during installation. Compared with other connection methods, the connection method of the present disclosure is simpler.

[0056] In a specific implementation manner, as Figure 4 and Figure 5 shown, a groove for accommodating part of the filter element 5 is provided on the filter element body 1;

[0057] The snap mechanism 13 includes at least one fixed snap 131 provided on the inner wall of the groove and cooperating with the second engaging protrusion 51 on the filter element 5;

[0058] The limiting mechanism 14 includes limiting ribs 141 provided on the inner wall of the groove and located on both sides of the snap for cooperating with the second engaging protrusion 51 on the filter element 5.

[0059] The snap mechanism 13 can tightly clamp the filter element body 1 and the filter element 5, and the limiting mechanism 14 is used to prevent relative rotation between the two when the filter element body 1 and the filter element 5 are tightly clamped. The cooperation of the snap mechanism 13 and the limiting mechanism 14 strengthens the connection between the filter element body 1 and the filter element 5.

[0060] The present disclosure does not need to remove the filter material in the original filter element 5 in the water purifier, but a cleaning filter element is provided between the original filter element 5 and the water purifier. Therefore, the structure of the present disclosure is simpler, the volume is smaller, the production and manufacturing costs are low, and the cooperation of the snap mechanism 13 and the limiting mechanism 14 makes the connection between the filter element body 1 and the filter element 5 firm and there is no relative rotation. Therefore, the cooperation of the filter element body 1 and the filter element 5 extends the length of the present disclosure and solves the problem that the filter element body 1 in the present disclosure is not easy to be installed on the water purifier due to its short length.

[0061] In a possible implementation, a water stop valve assembly for preventing water from overflowing from the channel openings is further provided at the channel openings of the first channel 2 and the second channel 3.

[0062] In a possible implementation, a water stop valve assembly is further provided at the channel openings of the first channel 2, the second channel 3, and the third channel 4.

[0063] The water stop valve assembly includes

[0064] a water stop valve body;

[0065] a sealing ring sleeved on the outer wall of the water stop valve body and sealingly connected to the inner wall of the first channel 2 or the second channel 3 or the third channel 4 where the water stop valve body is located;

[0066] a return spring for pushing the water stop valve body outwards in the direction away from the channel openings of the first channel 2 or the second channel 3 or the third channel 4 where the water stop valve body is located.

[0067] The working principle of cleaning the filter element in the present disclosure is specifically as follows:

[0068] Unscrew the original filter element 5 in the water purifier from the water purifier, insert the side of the filter element 5 with the second engaging convex block into the cleaning filter element, and fix the filter element 5 through the fixing buckle 131 and the limiting rib 141 of the cleaning filter element; hold one side of the filter element 5 in the combination of the filter element 5 and the cleaning filter element, and rotate and screw the fixed combination of the filter element 5 and the cleaning filter element into the water purifier, so that the raw water inlet on the water circuit board in the water purifier is inserted into the first channel 2, the wastewater outlet is inserted into the second channel 3, and / or the pure water outlet is inserted into the third channel 4; each water inlet pushes the water stop valve assembly into each channel, so that the raw water inlet of the water purifier communicates with the first channel 2, the wastewater outlet communicates with the second channel 3 and / or the pure water outlet communicates with the third channel 4, turn on the water production function of the water purifier, the water pump on the raw water channel in the water purifier pumps water from the raw water tank, passes through the first channel 2 and the cavity 11 in sequence and then is discharged to the wastewater outlet on the water purifier through the second channel 3, and is discharged to the pure water outlet through the third channel 4, or close the faucet of the pure water outlet, the water pump on the raw water channel in the water purifier pumps water from the raw water tank and passes through the first channel 2 and the cavity 11 in sequence and then is discharged to the wastewater outlet on the water purifier through the second channel 3, and continuously rinse until the scale in the water purifier is rinsed clean. In a possible implementation, the water in the raw water tank is a mixture of citric acid and raw water.
