Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of domestic water treatment, and particularly relates to a physical principle bathing water optimization processor. BACKGROUND

[0002] The current basic washing hair and bathing relies on shampoo, shower gel, hair conditioner, and soap, etc. The washing products are all synthesized from various application demand substances and chemical products, and most of the components are chemical synthetic preparations. No matter how much the content is, through skin absorption and blood transportation, accumulation will cause harm to human skin and organs (see dermal toxicology). In order to inhibit bacterial growth, chlorine is added to tap water as a bacterial killing inhibitor. During the bathing process, the residual chlorine in the water will be absorbed through the skin pores and transported by the blood, causing harm to the skin and internal organs (see dermal toxicology). Symptoms such as repeated dandruff, more keratin layer on the skin after bathing (dandruff), and back itching indicate the side effects of washing products. According to statistics, domestic sewage discharge pollution accounts for 70% of water pollution in China. Washing with washing products and chemical preparations for cleaning tableware, etc. The chemical components in the sewage discharge cannot be completely removed. After a certain level of treatment in the sewage treatment plant, it is discharged into rivers. Water with chemical components continues to pollute surface and underground water sources. Pollutants circulate continuously, and human harm cannot be stopped.

[0003] The existing filtering equipment mainly optimizes the bathing water such as washing hair and bathing by physical principle. The equipment contains mineral composition functional filler, which is not only used for water filtration, but also can achieve other effects through part of the functional filler, for example: energy ceramics and other materials can not only adsorb small volume impurities in water through the porous surface of the material, thereby achieving a certain physical filtering effect. At the same time, due to different application scenarios, the subdivision requirements for water quality are gradually increasing, for example, bathing water and laundry water. In addition to other corresponding water quality indicators, the hardness of the water will also be required. The water stain generated by softening treatment will be reduced, especially for bathing water, which can avoid the blockage of the small gap of the shower head after long-term use. At the same time, soft water has good foaming effect, which can reduce the amount of surfactant used, and has good body comfort.

[0004] However, the existing soft water machine structure is relatively complex, and needs to be modified to the water supply pipeline, which not only has high cost, but also does not have installation conditions for part of the old houses. SUMMARY

[0046] Embodiment 1:

[0047] The present embodiment discloses a physical principle shower water optimization processor for filtering and treating domestic water, which is mainly arranged directly on the shower pipeline, and generally on the pipeline above the ball valve of the shower. In order to be compatible with the existing pipeline, it has a universal connector, which is connected in series in the pipeline through cutting or disassembly, and a valve is further arranged on the pipeline after the water outlet to guide the water flow to the overhead shower head or handheld shower head.

[0048] Specifically, the optimization processor of the present embodiment comprises a filter part 1, which has a filter channel for water flow in the filter part 1, the filter channel has at least two ports for connecting external pipelines, namely a filter water inlet 3 and a filter water outlet 4, and a filter core is arranged in the filter channel; it also comprises a backwashing part 2, which has a backwashing channel in the backwashing part 2, and the backwashing channel has two ports: a backwashing water inlet 5 and a backwashing water outlet 6.

[0049] The filter part 1 is movably connected with the backwashing part 2, the filter part 1 and the backwashing part 2 have at least two fixed relative positions, and the filter part 1 is provided with a communication port for connecting the backwashing channel and the filter channel; when the filter part 1 and the backwashing part 2 are in the first relative position, the two ports of the backwashing channel are blocked by the filter part 1; when the filter part 1 and the backwashing part 2 are in the second relative position, the filter water inlet 3 of the filter channel is communicated with the backwashing water inlet 5 of the backwashing part 2, and the backwashing water outlet 6 is communicated with the communication port of the filter part 1.

[0051] A separate water inlet cavity is arranged at the inlet pipe of the filter part 1, a three-way valve is arranged in the water inlet cavity, and the three-way valve is connected with the backwashing part 2, the filter part 1 and the inlet pipe through pipelines. The control part of the three-way valve is linked with the backwashing part 2. Since the filter part 1 is fixed on the external structure, i.e. the wall surface or the pipeline, and remains in a fixed state, and the backwashing part 2 is movably connected with the filter part 1, the backwashing part 2 can be moved to drive the three-way valve to link, so as to change the direction of water flow in the water inlet port from the filter part 1 to the backwashing part 2, and then the water flows into the filter part 1 through the backwashing water outlet 6 of the backwashing part 2.

[0052] Further, the filter part 1 has a separate backflow channel 8, the communication port is communicated with the backflow channel 8, and the backflow channel 8 further has a backflow port 7 communicated with the filter channel, and the backflow port 7 is arranged at the filter water inlet 3 of the filter channel.

[0053] In another embodiment, the filter part 1 has a leakage port, when the filter part 1 and the backwashing part 2 are in the first relative position, the leakage port is blocked and closed by the backwashing part 2, and when the filter part 1 and the backwashing part 2 are in the second relative position, the water from the backwashing channel into the filter channel falls out of the leakage port after passing through the filter core.

[0054] Further, the backwashing part 2 and the filter part 1 are both cylindrical structures, the backwashing part 2 is sleeved outside the filter part 1 and slides reciprocally along the outer wall of the filter part 1, at least two sets of clamping limiting components are arranged on the backwashing part 2 and the filter part 1, and the filter part 1 and the backwashing part 2 are limited to be in the first relative position or the second relative position through the clamping limiting components.

[0055] The communication port is arranged on the outer wall of the filtering part 1 and is blocked and closed by the rubber sealing element arranged on the communication port and matched with the outer surface of the shell of the moving backwashing part 2; when the filtering part 1 and the backwashing part 2 are in the second relative position, the port arranged on the outer wall of the shell of the backwashing part 2 is aligned with the communication port and is in communication.

[0056] The filtering water inlet 3 of the filtering part 1 is arranged on the outer wall covered by the backwashing part 2, the inner side of the filtering water inlet 3 is in communication with the external pipeline, and a flow switching port 9 is further arranged on the covered outer wall; a first communication part is arranged on the outer wall of the shell of the backwashing part 2 and the filtering part 1, when the filtering part 1 and the backwashing part 2 are in the first relative position, the filtering water inlet 3 and the flow switching port 9 are connected by the first communication part, and the water flow enters the flow switching port 9 from the inner side of the filtering water inlet 3 through the first communication part and then enters the filtering channel; when the filtering part 1 and the backwashing part 2 are in the second relative position, the backwashing water inlet 5 arranged on the outer wall of the shell of the backwashing part 2 and the filtering part 1 is in communication with the filtering water inlet 3, the flow switching port 9 is blocked and sealed by the rubber sealing element arranged on the outer wall of the shell of the backwashing part 2, the water flow enters the backwashing channel from the filtering water inlet 3 and then enters the filtering channel through the backflow channel 8, contacts the filter core and finally flows out from the filtering water outlet 4.

[0057] Since the backwashing part 2 in the embodiment has a large cavity, the filter core in the filtering part 1 is washed by the water flow through the backwashing part 2, the impurities attached to the surface of the filter core are removed after the cleaning of the filter core structure of some grating type, and the filter core can be cleaned and sterilized by adding part of the cleaning agent into the backwashing part 2.

[0058] Further, if a material for softening water is arranged in the filtering part 1 to soften the entering water, the material can be periodically washed and restored by the backwashing part 2. Specifically, the filter core of the filtering part 1 is active resin filler, and a plurality of granular displacement salt blocks are arranged in the backwashing part 2. Meanwhile, the filtering part 1 has a water outlet cavity and a water inlet cavity, the water outlet cavity is provided with a sensor for detecting the salinity of the outlet water, and a display screen is arranged on the exposed end surface of the filtering part 1.

[0059] Embodiment 2:

[0060] The embodiment is further optimized and defined based on the structure of the above-mentioned embodiment 1.

[0061] Specifically, as shown in Figures 1-5 the embodiment, the structure is shown in the figure, which is a cylindrical structure, and the water entering the top shower head or handheld shower head is filtered by being arranged on the shower pipeline, which avoids additional increase and adjustment of other structures and has good convenience.

[0062] As can be seen from the figure, the structure comprises a filter part 1 and a backwashing part 2 which are sleeved with each other, the filter part 1 has two upper and lower ports for connecting the shower pipe as water outlet port and water inlet port, and the water flow enters the filter part 1 from the lower faucet and then flows out from the water outlet port at the upper part of the filter part 1, and the water flow is controlled by the ball valve to flow into the top shower head or the handheld shower head respectively.

[0063] Further, the outer wall of the filter part 1 is a smooth cylindrical structure, and only the upper and lower end faces thereof are provided with annular clamping rings. The backwashing part 2 is sleeved on the outer wall of the filter part 1, and at least two ports, i.e. the backwashing water inlet 5 and the backwashing water outlet 6, are arranged on the surface thereof in contact with the filter part 1. The inner part of the backwashing part 2 is an annular cavity, and in order to accommodate the medicine, an annular enlarged cavity is arranged at the upper part thereof, and a cover is arranged on the annular surface of the enlarged cavity and is connected in a sealing manner through thread cooperation, so that the user can fill or replace the medicine by screwing off the cover and filling it inward.

[0064] As can be seen from the figure, the filter part 1 is divided into two chambers, i.e. a lower water inlet chamber and an upper filter chamber, by a partition plate, and a filter core is arranged in the filter chamber.

[0065] On the annular surface where the filter part 1 and the backwashing part 2 are attached, one opening is arranged on each of the upper and lower sides, i.e. the filter water inlet 3 and the backflow port 7, and the water outlet port at the center of the top of the filter part 1 is the filter water outlet 4, which is directly communicated with the filter chamber, and the water filtered by the filter core flows out from the filter water outlet 4. Due to the limitation of the partition plate, the water flowing in from the lower water inlet port cannot directly flow into the filter chamber from the inside of the filter part 1, but will first fill the entire water inlet chamber and then flow out from the filter water inlet 3 at one side of the water inlet chamber.

[0066] And an inwardly recessed annular cavity is arranged on the outer wall of the backwashing part 2 shell outside the filter part 1, which is a first communication part. The first communication part can cross the partition plate from the outside to enable the water flow in the water inlet chamber to flow into the first communication part through the filter water inlet 3. A flow diversion port 9 is also arranged on the outer surface of the filter part 1, which is also covered by the first communication part, so that the water flow flowing into the first communication part can directly enter the flow diversion port 9, and the flow diversion port 9 is communicated with the filter chamber, so that the water flow can smoothly enter the filter part 1 by bypassing the partition plate through the external first communication part structure.

[0067] The backflow port 7 at the upper part of the filter part 1 is blocked by the shell outer wall of the backwashing part 2, and the water flow entering the filter part 1 is filtered by the filter core and then directly flows out from the filter water outlet 4.

[0068] Further, since the backwashing part 2 can move along the filtering part 1, and in this embodiment, the moving mode is linear up and down along the axial direction. In order to achieve better fixing effect, the backwashing part 2 and the filtering part 1 have two relatively stable fixed positions, i.e. the first relative position and the second relative position.

[0069] The first relative position is shown in FIG. 1, and the cross-sectional view thereof is shown in FIG. 2. The second relative position is shown in FIG. 3, and the cross-sectional view thereof is shown in FIG. 4. Figure 3 The first relative position is shown in FIG. 1, and the cross-sectional view thereof is shown in FIG. 2. The second relative position is shown in FIG. 3, and the cross-sectional view thereof is shown in FIG. 4.

[0070] The first relative position is shown in FIG. 1, and the cross-sectional view thereof is shown in FIG. 2. The second relative position is shown in FIG. 3, and the cross-sectional view thereof is shown in FIG. 4. Figure 4 The first relative position is shown in FIG. 1, and the cross-sectional view thereof is shown in FIG. 2. The second relative position is shown in FIG. 3, and the cross-sectional view thereof is shown in FIG. 4.

[0071] The first relative position is shown in FIG. 1, and the cross-sectional view thereof is shown in FIG. 2. The second relative position is shown in FIG. 3, and the cross-sectional view thereof is shown in FIG. 4.

[0072] The first relative position is shown in FIG. 1, and the cross-sectional view thereof is shown in FIG. 2. The second relative position is shown in FIG. 3, and the cross-sectional view thereof is shown in FIG. 4.

[0073] In the embodiment, another communication mode is provided, i.e. the mode shown in the figure, the water inlet cavity of the filter part 1 is further provided with a separate opening, i.e. the backwashing communication port 10, which is arranged below the filter water inlet port 3 and is blocked by the outer wall of the shell of the backwashing part 2 in the first relative position. When the backwashing part 2 slides downward, the backwashing water inlet port 5 thereof is aligned with and communicated with the backwashing communication port 10, and the water in the water inlet cavity can enter the backwashing part 2 through the backwashing communication port 10. Since the upper diversion port 9 is blocked by the outer wall of the shell of the backwashing part 2, even if the water flow enters the first communication part through the filter water inlet port 3, it cannot continue to flow into the filter cavity.

[0074] Further, since the backflow port 7 is communicated with the filter cavity, if the water is discharged from the filter water outlet port 4, the water in the backflow port 7 may not be fully contacted with the filter core before being discharged from the filter water outlet port 4, causing the problem of low salt utilization rate. In order to improve the utilization rate, a backflow channel 8 is further separately arranged in the filter part 1. As shown in the figure, the backflow channel 8 is an annular space arranged close to the inner wall of the filter cavity, and the upper portion thereof is communicated with the backflow port 7, so that the water entering from the backflow port 7 is guided to flow downward by the backflow channel 8 and flows into the filter cavity at a position close to the diversion port 9. This scheme is mainly used for the scheme of using active resin filler as the filter core, to increase the contact time of the water passing through the backwashing part 2 with the active resin filler.

[0075] It is worth noting that in the above embodiment, the openings arranged on the annular surfaces of the sliding contact between the backwashing part 2 and the filter part 1 are provided with corresponding rubber seals. Since the openings are arranged in the form of several openings with equal central angles, and the rubber seals are generally arranged on the relatively fixed openings, i.e. all the openings of the filter part 1. The rubber seal is generally an annular component arranged in contact with the opening edge, and has good stability, always maintaining contact with the outer wall of the shell of the backwashing part 2 during sliding, and filling the gap by deforming to avoid water leakage. At the same time, it should be noted that this relatively linear sliding structure will have a structure for limiting and guiding on the contact surface, such as a sliding groove. And the contact surface is also coated with a good wear-resistant smooth coating, which can reduce the friction between the rubber seal and the moving part while ensuring low sliding friction, to avoid the rubber seal being displaced when the backwashing part 2 moves and affecting the sealing performance. By arranging a sliding groove structure with small tolerance, the relative sliding stability of the backwashing part 2 and the filter part 1 can be limited to ensure that the gap remains within a certain range.

[0076] And the water leakage and structural stability are related to many factors, mainly the selection of materials, size, assembly process and other comprehensive factors. The rubber seal can provide a theoretical sealing effect, and its actual sealing performance is adjusted by the specific manufacturer according to the above factors, and the embodiment does not make corresponding limitations.

[0077] At the same time, the backwashing part 2 is controlled by the user and is used to flush and regenerate the active resin filler in the filtering part 1 according to the needs in the corresponding period. The structure is simple and stable, and the size and relative proportion of the structure space are not limited, so that the size can be optimized according to the water inflow and other parameters. At the same time, in order to reduce the water flow speed in the backwashing process, in addition to reducing the size of all openings of the backwashing part 2, the water inflow is also reduced by controlling the external valve, which can also achieve the corresponding effect.

[0078] Further, a separate chamber is arranged in the filtering part 1 for arranging a circuit board, the circuit board uses a common single-chip microcomputer as a controller, and a program can be set for controlling the display screen arranged outside to display the corresponding content. Since the filtering part 1 is provided with a sensor for detecting salinity, the sensor is connected to the controller for data transmission. At the same time, a water flow power generation device is arranged in the filtering part 1, and a small-sized storage battery and an inverter are arranged, and when the water is sprayed normally, the water flow can drive the runner of the water flow power generation device to move and generate electricity. The control module is powered by the storage battery to detect the salinity of the outlet water, which is mainly used for detecting the softening degree of the outlet water. When the salinity is reduced, it can be determined that the amount of sodium and potassium ions in the water is reduced, which indicates that the amount of sodium and potassium ions in the active resin filler has been reduced to the extent that the displacement reaction cannot be effectively carried out, and the backwashing process is needed to restore the activity. At the same time, during the backwashing process, when the salinity increases and reaches a threshold value for a period of time, it also indicates that the activity has been restored, and the backwashing process can be stopped.

[0079] The excess salt water remaining in the filtering part 1 during the backwashing process can also be prompted to the user by the display screen, and the user can open the water and wash for a period of time before bathing.

[0080] Further, in order to prompt the user to perform the backwashing process at what time, a flowmeter is arranged in the filtering part 1, and the value detected by the salinity detection sensor is judged. If the salinity is lower than the preset value or the flow exceeds the preset value, the display screen can be prompted.

[0081] The present application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the present application. The above-mentioned specific embodiments should not be understood as limiting the protection scope of the present application, and the protection scope of the present application should be defined by the claims, and the specification can be used to explain the claims.
