Description

Technical Field

[0001] The invention relates to the technical field of water purifiers, and in particular to a multi-stage water purifier scale-inhibiting carbon rod filter element assembly and a water purifier. Background Art

[0002] The principle of a water purifier (for household or industrial use) is to obtain relatively clean water by graded filtration using various filter elements, such as PP cotton filter elements, activated carbon, ultrafiltration membranes, RO membranes, carbon rod filter elements, etc. For details, please refer to the relevant content in publication number CN111991904A.

[0003] The scale problem in the water body is one of the factors that affect the purification effect. Specifically, scale affects the water flow state due to clogging the filter material. Taking the carbon rod filter element as an example, the water purification effect of the carbon rod filter element is very good and is less affected by scale. Please refer to the relevant content in the publication number CN105771422A. However, the filter materials in other positions are relatively greatly affected by scale. Especially for the water purifier with an additional heating unit, the scale generation efficiency is relatively high. Therefore, in the overall water purification process, scale mainly affects the filter element structure except the carbon rod filter material. However, because the carbon rod filter element is the last process in the water purifier, it will also indirectly increase the influence of scale on the carbon rod filter element, thereby affecting the water purification effect. The present invention proposes a solution to this. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-stage water purifier scale-inhibiting carbon rod filter element assembly and a water purifier. According to the basic water purification principle of the water purifier, although the carbon rod filter material itself is relatively less affected by scale, because the carbon rod filter material belongs to the last process in the water purification system, the scale impact problem that may be generated by the filter material in other positions will also be indirectly fed back to the carbon rod filter material, thereby affecting the overall water purification effect.

[0005] The object of the present invention can be achieved by the following technical scheme: a multi-stage water purifier scale-inhibiting carbon rod filter element assembly, applied in the water purifier, comprising a single-stage installation sleeve, a filter material sleeve and a central lever, wherein the filter material sleeve is placed in the single-stage installation sleeve, and the interior of the filter material sleeve is used to place filter fillers, a clean water chamber is formed between the outer wall of the filter material sleeve and the inner wall of the single-stage installation sleeve, and the central internal position of the filter material sleeve is set as a cavity, and the central lever is set in the cavity along a direction parallel to the height of the filter material sleeve;

[0006] A bottom filter sleeve, a dynamic seat and a diverter seat are arranged at the lower end of the single-stage mounting sleeve. The dynamic seat is slidably connected in the cavity, and the dynamic seat and the diverter seat are slidably connected along the vertical direction. The diverter seat is located in the middle of the dynamic seat and the bottom filter sleeve.

[0007] It is further configured as follows: a plurality of arc-shaped shifting bars are installed on the outer wall of the central shifting rod, and the arc-shaped shifting bars are in contact with the inner wall of the cavity in the filter material sleeve.

[0008] It is further configured as follows: a permanent magnet block is installed at the top position of the central lever, the permanent magnet block is rotatably connected to the single-stage mounting sleeve, and an energized winding coil corresponding to the permanent magnet block is installed on the single-stage mounting sleeve.

[0009] It is further configured as follows: the lower end of the central lever is threadedly connected to the dynamic seat, a filter partition is provided at the middle end of the bottom filter sleeve, and the bottom filter sleeve is divided into a storage bin and a reflux bin from top to bottom by the filter partition.

[0010] It is further configured as follows: the bottom filter sleeve is fixedly connected to the diverter seat, and a water permeable opening is provided on the outer wall of the diverter seat corresponding to the flow storage bin.

[0011] The present invention also proposes a water purifier, comprising a mounting frame, wherein the mounting frame is used to fix a filter element module, wherein the filter element module is formed by a plurality of single-stage mounting sleeves and filter material sleeves arranged and combined along a linear equidistant arrangement, a double-way pipe is provided at the upper end of the single-stage mounting sleeve, and a positive flow pipe and a reverse flow pipe are respectively provided between the single-stage mounting sleeves at adjacent positions.

[0012] It is further configured as follows: the two ends of the positive flow pipe are respectively connected to the clean water tank and one of the interface positions in the two-way pipe, and a flow meter is provided on the positive flow pipe, and the two ends of the reverse flow pipe are respectively connected to the reflux tank and the other interface position in the two-way pipe.

[0013] It is further configured as follows: the filter material sets are numbered i in sequence along the linear direction, where i is a natural positive integer; the positive flow pipe is used to connect the filter material sets numbered i-1 and i along the water flow direction; and the water flow direction in the reverse flow pipe is opposite to that in the positive flow pipe.

[0014] It is further configured that: the filter filler in the filter material sleeve in the last position is a carbon rod.

[0015] The present invention has the following beneficial effects:

[0016] 1. Based on the structure of conventional water purifiers, the water purifier in the present invention is formed by combining multiple filter material sleeves. The type of filter filler can be selected according to the actual application environment, and the positive flow pipe is used as the direct connection structure between each single-stage installation sleeve to ensure the normal flow of water during the water purification process. Specifically, a central lever is added to the center position inside the filter material sleeve. The central lever can switch the action process according to the degree of scale influence during the actual operation process. When it is in a static state, it will not affect the filtering effect of the filter material sleeve at this location. On the contrary, when it is in a dynamic state, the scale attached to the inner wall of the filter material sleeve can be peeled off and shaken off by the rotation process of the central lever;

[0017] 2. Explanation in combination with the above content: The key is to use the flow meter on the positive flow pipe as a key structure to feedback whether there is a scale effect. Its essence is: without considering the filter filler, the water flow direction is in a relatively constant state, on the contrary, after the scale effect appears, it will produce an obvious fluctuation state, and the center lever is mainly used as the electromagnetic induction phenomenon as the power source to maintain the normal rotation of the center lever pair. In the rotation process of the center lever, the combined operation form of spiral + sliding is also used to drive the dynamic seat to have the ability to slide up and down. Its purpose is to transfer the peeled scale mixed water to the storage bin for direct filtration;

[0018] 3. It should also be noted that the filtration environment in each filter material set is set independently, and the scale stripping process does not interfere with each other, and further limits the direction of the water in the reflux pipe. Its essence is to use the reflux pipe to "return" the water that has not been filtered in a certain level of filter material set to the previous level, and the scale problem in the previous level of filter material set will not affect the filter material set in the next level. Its key purpose is to avoid the scale impact in each level of filter material set from "superposition" and aggravate the impact on subsequent carbon rod filter materials.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: In view of the basic water purification principle of the water purifier, although the carbon rod filter material itself is relatively less affected by scale, because the carbon rod filter material belongs to the last process in the water purification system, the scale problem that may be generated by the filter material in other positions will also be indirectly fed back to the carbon rod filter material, thereby affecting the overall water purification effect. The following technical solutions are proposed:

[0029] Reference Figures 1 to 6 In this embodiment, a multi-stage water purifier scale-inhibiting carbon rod filter element assembly is used in a water purifier, and includes a single-stage installation sleeve 2, a filter material sleeve 6 and a central lever 8. The filter material sleeve 6 is placed in the single-stage installation sleeve 2, and the filter material sleeve 6 is used to place filter fillers. A clean water chamber is formed between the outer wall of the filter material sleeve 6 and the inner wall of the single-stage installation sleeve 2, and the central internal position of the filter material sleeve 6 is set as a cavity, and the central lever 8 is set in the cavity along a direction parallel to the height of the filter material sleeve 6;

[0030] A bottom filter sleeve 9, a dynamic seat 12 and a diverter seat 11 are arranged at the lower end of the single-stage mounting sleeve 2. The dynamic seat 12 is slidably connected in the cavity, and the dynamic seat 10 and the diverter seat 11 are slidably connected in the vertical direction. The diverter seat 11 is located in the middle position between the dynamic seat 12 and the bottom filter sleeve 9. A plurality of arc-shaped strips are installed on the outer wall of the center lever 8, and the arc-shaped strips are in contact with the inner wall of the cavity in the filter material sleeve 6.

[0031] Basic principle: briefly explain the water purifier, its key structure is the filter element inside it, there are many types of filter materials, which can be selected according to the actual application environment, such as paper filter element, chemical fiber filter element, metal mesh filter element, metal powder sintered filter element, PP filter element, line gap filter element, activated carbon filter element, etc., the filter material sleeve 6 proposed in the present invention is mainly used to hold one of the above filter materials to form a filter element, this part is not explained in detail in the present invention;

[0032] It should be noted that most water bodies will have the problem of scale, especially for water purifiers with additional heating structures. Although the filter element can filter the water body to obtain relatively clean pure water, scale will slowly accumulate during the filtration process. The scale is mainly attached to one side of the filter element, which directly affects the filtering effect of the filter element.

[0033] Refer to this Figures 3 to 5 To illustrate, the water body enters directly from the upper end of the single-stage installation sleeve 2 into the cavity of the filter material sleeve 6. After being filtered by the filter filler, the water body enters the clean water tank, and the scale that may be produced is mainly attached to the inner wall of the cavity. During normal operation, Figure 5 The central lever 8 does not rotate. On the contrary, when scaling occurs, the central lever 8 rotates in a directional manner, the purpose of which is to break up and peel off the scale attached to the inner wall of the cavity. This part is the basic content of the present invention.

[0034] Example 2: Based on Example 1, the scale stripping process is supplemented:

[0035] A permanent magnet block 10 is installed at the top position of the center lever 8, and the permanent magnet block 10 is rotatably connected to the single-stage mounting sleeve 2. The single-stage mounting sleeve 2 is installed with an energized winding coil 7 corresponding to the permanent magnet block 10. The lower end of the center lever 8 is threadedly connected to the dynamic seat 12. A filter baffle is provided at the middle end position of the bottom filter sleeve 9, and the bottom filter sleeve 9 is divided into a storage bin 901 and a reflux bin 902 from top to bottom by the filter baffle. The bottom filter sleeve 9 is fixedly connected to the diverter seat 11, and a water permeable port 13 is provided on the outer wall of the diverter seat 11 corresponding to the storage bin 901.

[0036] Solution description: As shown in the first embodiment, a permanent magnet block 10 is installed on the upper end of the center lever 8, and the permanent magnet block 10 is limited to a ring shape, so that the center lever 8 has the ability to rotate through the permanent magnet block 10 and the single-stage mounting sleeve 2, and a powered winding coil 7 is further provided, and the powered winding coil 7 in the powered state is used as a power source structure, so that the permanent magnet block 10 is directional rotated under the action of the electromagnetic field generated by the powered winding coil 7, thereby maintaining the directional rotation of the center lever 8;

[0037] The key contents of the present invention can be referred to Figure 6 ,from Figure 6 It can be understood that: both ends of the cavity are open, but the lower end of the cavity can be temporarily blocked by the dynamic seat 10, which is specifically manifested as: in the initial state, that is, the center lever 8 does not rotate, then the dynamic seat 10 maintains the state of blocking the lower end of the cavity, and when the center lever 8 starts to rotate, it includes the following contents:

[0038] S1: First, the threaded connection between the lower end of the central lever 8 and the dynamic seat 10 is maintained. In essence, the dynamic seat 10 is spirally moved under the action of the central lever 8, but the dynamic seat 10 is affected by the interference from the shunt seat 11. The dynamic seat 10 can only be slidably connected on the shunt seat 11, so the spiral movement is coordinated to ensure that the dynamic seat 10 can only move linearly up and down;

[0039] S2: Secondly, it is necessary to limit the distance between the dynamic seat 10 and the lower end of the cavity, and the purpose is that during the process of the dynamic seat 10 slowly moving downward, the dynamic seat 10 still maintains the blocking action on the cavity, and the purpose is to prolong the time for the central lever 8 to perform the stripping action on the scale attached to the cavity, so as to ensure that the scale is broken up and falls and is concentrated at the upper end of the dynamic seat 10;

[0040] S3: After the dynamic seat 10 continues to move downward and opens the lower end channel of the cavity, the water mixed with scale flows into the storage bin 901 through the water permeable port 13 and is directly filtered. The scale is isolated in the storage bin 901. Finally, the dynamic seat 10 is driven to reset upward again through the reverse rotation process of the center lever 8 to resume the blocking process of the cavity.

[0041] Embodiment 3: After Embodiment 1 and Embodiment 2 are put into a water purifier, the operation process thereof is described:

[0042] A water purifier includes a mounting frame 1, the mounting frame 1 is used to fix a filter element module, the filter element module is formed by a plurality of single-stage mounting sleeves 2 and filter material sleeves 6 arranged and combined along a linear equidistant arrangement, a double-pass pipe is provided at the upper end of the single-stage mounting sleeve 2, and a positive flow pipe 3 and a reverse flow pipe 5 are respectively provided between the single-stage mounting sleeves 2 at adjacent positions, and both ends of the positive flow pipe 3 are respectively connected to a water purification tank and one of the interface positions in the double-pass pipe;

[0043] A flow meter 4 is provided on the positive flow pipe 3, and both ends of the reverse flow pipe 5 are respectively connected to the reflux bin 902 and another interface position in the two-way connecting pipe. The filter material sleeves 6 are numbered i in the linear direction, where i is a natural positive integer. The positive flow pipe 3 is used to connect the filter material sleeves 6 numbered i-1 and i along the water flow direction. The water flow direction in the reverse flow pipe 5 is opposite to that of the positive flow pipe 3. The filter filler in the filter material sleeve 6 in the last position is a carbon rod.

[0044] Solution description: Conventional water purifiers require multi-stage filtration structures to cooperate with each other, but the filter element in the last stage of filtration must be a carbon rod, because carbon rods have multiple effects such as removing odors, removing organic matter, and removing heavy metals. Figure 1 For example, each filter material set 6 is specifically numbered as i from right to left, i=1, 2, 3...i, and the filter material in the filter structure before the carbon rod filter element is not described in detail in the present invention, and is described in combination with the first and second embodiments as follows:

[0045] S4: Under normal conditions, the water body is first directly injected into the first-stage filter structure. Taking a household water purifier as an example, without adding a booster pump, the water body injected into the filter structure has a certain pressure. After multiple filtrations, although the water body pressure decreases, the decrease will not be significantly different. For this, the present invention mainly uses the positive flow pipe 3 as a connecting pipe structure between each filter material set 6. For example, when the water body flowing out of the i-1-stage filter structure flows into the i-stage filter structure, if the values ​​detected by the flow meter 4 between the two are significantly different, it can be directly indicated that the filter material set 6 in the i-1-stage filter structure has an obvious scale problem. The value of the flow meter 4 and the judgment basis are determined according to the actual application environment and are not limited in the present invention.

[0046] S5: As for the carbon rod filter element structure, although it has a good scale inhibition effect, it will also indirectly affect the carbon rod filter element structure due to the scale problem in the previous filter element structure. In this regard, each filter element structure independently completes the parts of S1 to S3 in Example 2, which are specifically manifested as follows: According to the content in S4, when there is an obvious fluctuation in the flow meter 4 between the filter material sleeves 6 in two adjacent positions, the filter element structure in the corresponding stage will undergo a scale stripping process, and this process is explained: When the dynamic seat 10 blocks the cavity, the water body can use the filter material sleeve 6 as a medium channel under its own pressure to complete the filtering action, but when the dynamic seat 10 is in an open state, it is difficult for the water body to maintain the pressure environment and return to the filter material sleeve 6 in the previous stage along the water permeable port 13-storage chamber 901-reflux chamber 902-reflux pipe 5. It can be understood that the stripped scale is mainly retained in the storage chamber 901. On the one hand, it reduces the filtering effect in the single-stage filter element structure. The key lies in reducing the "superposition effect" in the carbon rod filter element structure.

[0047] In summary: the improvement is based on the conventional principle of the water purifier. Its essence is to add positive flow pipes and reverse flow pipes according to the setting position of each filter material set. The positive flow pipe is used to maintain the direction of water flow in each stage of water filtration, and judge the influence of scale in the single-stage filter material according to the flow feedback. The center lever is used as the actuating part to shake off the attached scale, and return the scale to the storage bin for direct filtration. Finally, the reverse flow pipe is used to "return" the water that has not been filtered in a certain level of filter material set to the previous level. Its key purpose is to avoid the influence of scale in each level of filter material set from "superposition" and aggravate the influence on subsequent carbon rod filter materials, and reduce the degree of influence between each level of filter materials on the basis of maintaining normal water purification effect.
