Example 1
The purifier that this embodiment provided is suitable for and is connected with outside water source to filter the water source, thereby get rid of the filtration of floater, heavy metal, bacterium, microorganism etc. in the water source, guarantee that user's drinking water is healthy. The water source may be lake water, groundwater, rainwater, etc., and may be selected according to actual conditions, and is not specifically limited herein.
The above determination of drinking water health is based on TDS values. TDS (total dissolved solids) is the total dissolved solids, also known as total dissolved solids, and higher TDS values indicate more dissolved material and more impurities in the water.
Specifically, this purifier includes leading filter assembly 1, reverse osmosis filter assembly 2 and first water route conveyor components 6, leading filter assembly 1 and water source intercommunication are suitable for and filter the water source. And the reverse osmosis filter assembly 2 is communicated with the preposed filter assembly 1 through a conveying pipeline 3, and the water source filtered by the preposed filter assembly 1 is filtered again under the action of pressure difference, so that pure water is obtained. Wherein, the pure water is the water meeting the drinking water requirement. Then, the pure water is delivered out of the water purifier through the first waterway delivery assembly 6 communicated with the pure water port of the reverse osmosis filtering assembly 2, thereby completing the process of filtering and purifying the water source.
The prefilter assembly 1 may be composed of one or more filter elements, for example, one or more filter elements selected from PP cotton, carbon fiber, granular carbon, compressed carbon, and activated carbon, according to actual filtering requirements, and is not limited herein. Through the arrangement, the front-end filter assembly 1 can filter and remove large-particle impurities contained in the water source. Alternatively, the pre-filter assembly 1 may also comprise a composite filter element of UFC, etc., in order to reduce the overall volume of the water purification device.
The reverse osmosis filter assembly 2 includes a reverse osmosis filter element 22, and a high pressure pump 21 communicating the reverse osmosis filter element 22 and the communication line, the high pressure pump 21 being adapted to increase the water source filtered by the pre-filter assembly 1 to create a sufficient pressure differential within the reverse osmosis filter element 22 to enable the water source to be filtered by the reverse osmosis filter element 22. In this embodiment, the reverse osmosis filter element 22 may be an RO reverse osmosis membrane or an ultrafiltration membrane. Taking RO reverse osmosis membrane as an example, RO reverse osmosis membrane is a high and new membrane separation technology, the filtration pore diameter of RO reverse osmosis membrane is as small as nanometer, under certain pressure, water molecule can pass through the membrane surface, and inorganic salt, heavy metal ion, organic matter, colloid, bacteria, virus and other impurities can not pass through, thus achieving the purpose of removing impurities in water source 2, therefore, the water purification device using reverse osmosis membrane has the advantages of good water quality, low energy consumption, no pollution, simple process, simple and convenient operation and the like.
The first water path conveying assembly 6 comprises a first water path conveying pipeline 61, a second one-way valve 62 communicated with the first water path conveying pipeline 61 and a high-pressure switch 63, wherein the first water path conveying pipeline 61 is communicated with a pure water outlet of the reverse osmosis filtering assembly 2, and the prepared pure water is conveyed. The high voltage switch 63 can cut off the power supply to stop the water production when the pure water produced is full. Accordingly, when the amount of pure water produced becomes small, the high-voltage switch 63 is turned on to continue the production of water. And second check valve 62 sets up on first water route pipeline 61 to prevent the pure water backward flow, and then lead to high-pressure switch 63 to open and stop repeatedly, the energy saving and extension purifier's life.
The water purifying device also comprises a second water path conveying component 7 communicated with the wastewater outlet of the reverse osmosis filtering component 2, and the second water path conveying component 7 comprises a second water path conveying pipeline 71 and a wastewater valve 72 connected with the second water path conveying pipeline 71. One end of the second waterway transmission pipeline 71 is connected with the waste water outlet, and the other end of the second waterway transmission pipeline 71 is connected with the sewage discharging part or the sewage discharging pipeline. Wherein, the waste water valve 72 is in an open state, and the waste water filtered by the pre-filter assembly 1 and the reverse osmosis filter assembly 2 is directly discharged into a sewage discharging part or a sewage discharging pipeline through the second waterway transmission pipeline 71 and the waste water valve 72. When the water purifying device needs to be refitted or the second waterway delivery pipeline 71 is not communicated with the sewage discharging part or the sewage discharging pipeline, the waste water valve 72 is adjusted to be in a closed state so as to ensure that waste water does not flow out of the second waterway delivery pipeline 71, and therefore the waste water is prevented from polluting the installation environment of the water purifying device.
The water purification device also comprises a second switch part 8 arranged on the communication pipeline. In this embodiment, the second switch 8 is an electromagnetic valve, which can be opened or closed according to actual requirements to obtain the final pure water.
Among the prior art, when purifier is made water once more after a period of shutting down, the TDS value of the first cup of water that the user connects can be higher than the TDS value of healthy drinking water, therefore is unfavorable for that drinking water is healthy.
To solve this technical problem, the following measures are generally taken: 1. when the water source is tap water, the tap water is used for flushing after the water is produced by the water purifying device, so that the tap water replaces concentrated water in the water purifying device; 2. the water storage tank is added on the basis of the original water purifying device to contain pure water, and the water purifying device dilutes the pure water with high TDS with the pure water in the water storage tank or carries out backwashing of the pure water during water production; 3. the waterway system of the water purifying device is changed. Namely, the high-pressure pump 21 continues to work, and the water storage environment of the reverse osmosis filter assembly 2 is relieved; 4. and adding a software control program so as to indirectly flush the pure water side of the reverse osmosis filtering component 2. However, the above measures may increase the cost of the water purifying device, or the flushing effect is not ideal, or the water purifying device often works to cause the aging of the components in the water purifying device, shorten the service life of the water purifying device, and reduce the user experience.
Therefore, in order to avoid the emergence of above-mentioned condition, and can make purifier after a period of shutting down, the first cup water that the user connects when launching again accords with the quality of water requirement of healthy drinking water, the utility model discloses a purifier still includes detection module 5 and circulation water route subassembly 4.

Moreover, the increase of the components affects the whole volume of the water purifying device, the cost is low, and the burden on a user can not be caused.
In another embodiment, the second sensing member 52 is a target trigger sensor adapted to be triggered by an external force. That is, when the user applies an external force to the second sensing member 52, the second sensing member 52 is triggered.
