Description

Technical Field

[0001] The present invention relates to the technical field of particle separation and capture, and in particular to a particle separation and capture device specially used for a water purifier. Background Art

[0002] With the development of industrialization and urbanization, water pollution is becoming increasingly serious, including tiny particulate matter such as mud, rust, microorganisms, etc. These particulate matter not only affect the transparency and taste of water, but also carry harmful substances or bacteria, posing a threat to human health. Therefore, particle separation and capture devices dedicated to water purifiers have emerged. Particle separation and capture devices include filter media, separation layers or other types of capture mechanisms, which are used to effectively prevent particulate matter from passing through, causing it to precipitate or be captured inside the device, thereby purifying the water source.

[0003] However, the traditional capture device is installed inside the water purifier by bolts, and some installation tools or operating steps are required for disassembly. For ordinary users, the disassembly process is relatively complicated, and the device cannot be easily pushed out of the water purifier, and it is difficult to replace the device. If the device is not replaced for a long time, too many impurities are likely to accumulate inside the device. The impurities will clog the filter holes of the capture device, causing the efficiency of filtering water quality to gradually decrease, resulting in the water purifier being unable to effectively remove impurities and pollutants in the water, thereby reducing the purification effect of the water purifier. The capture device needs to be disassembled to clean it, which requires professional personnel or maintenance services, increasing the cost and difficulty of maintenance and repair.

[0004] Therefore, the present invention proposes a particle separation and capture device specifically for a water purifier to improve the deficiencies of conventional technologies, and is capable of regularly cleaning the particles deposited or captured inside the particle separation and capture device, thereby keeping the inside of the device clean and improving separation efficiency.

[0015] The particle separation and capture device for a water purifier provided by the present invention has the following beneficial effects:

[0016] 1. The cover plate is driven downward by the particle separation filter cartridge to be installed. The second slider is parallel to the inclined surface of the first slider. The plug drives the first slider to touch and squeeze the second slider. The first slider is moved to the bottom of the second slider through the retractable action of the first spring. The plug will be inserted into the water purifier housing. When the particle separation filter cartridge is used for a long time and ages, the retractable action of the first spring causes the particle separation filter cartridge to move upward and drive the plug out of the water purifier housing.

[0017] 2. The third slider is driven to slide inside the threaded groove by moving the rotating shaft downward. During the sliding process of the third slider, the first cylinder is rotated and the rotating plate is driven to rotate. The shape of the arc groove and the vertical groove on the rotating plate makes the auxiliary plate scrape the inner wall of the particle separation filter cartridge. The scraping of the auxiliary plate gathers the particles precipitated or captured inside the particle separation filter cartridge, making it easier to clean. This helps to maintain the filtration efficiency of the particle separation filter cartridge and ensure the long-term and effective operation of the filtration system. When cleaning the particle separation filter cartridge, the particles are gathered by scraping the auxiliary plate, which can complete the cleaning work more quickly and thoroughly, thereby improving work efficiency.

[0018] 3. The auxiliary plate is driven to scrape the captured particles inside the particle separation filter cartridge by moving the rotating shaft downward, while driving the connecting column and the round cover downward. When the connecting column moves downward, it will touch the inclined block. Through the action of the reset spring installed on the square block and the inner wall of the square groove, the inclined block drives the square block to move into the square groove and the connecting column to move into the second cylinder, so that the square block and the inclined block are located in the bottom plate and the second cylinder respectively. The downward movement of the round cover will press the bottom plate downward, so that there is an opening at the bottom of the particle separation filter cartridge. The auxiliary plate scrapes the particles into the bottom cover to clean them, which can effectively remove the particles from the inside of the particle separation filter cartridge, keep the inner surface of the particle separation filter cartridge clean, improve the contact efficiency between the particles and water, and thus improve the filtration efficiency. Regular cleaning of particles can reduce their accumulation in the particle separation filter cartridge, extend the service life of the particle separation filter cartridge, reduce the frequency of maintenance and replacement of the particle separation filter cartridge, and reduce the cost of use.

[0040] The inclined surfaces of the first slider 63 and the second slider 67 are parallel, and the cover plate 61 is driven downward to be installed by the particle separation filter cartridge 5. The second slider 67 is parallel to the inclined surface of the first slider 63, and the plug 62 will drive the first slider 63 to touch and squeeze the second slider 67.

The user can easily replace the particle separation filter cartridge 5 by himself without the need for professionals or maintenance services, thereby reducing the cost and difficulty of maintenance and repair, improving the convenience of use, and saving the time of replacing the filter element.

[0041] The cleaning assembly 7 includes a hollow column 71, and a first cylinder 72 is rotatably connected to the top of the particle separation filter cartridge 5. A threaded groove 73 is provided on the inner wall of the first cylinder 72, and a third slider 74 is slidably connected inside the threaded groove 73. A rotating plate 75 is fixedly connected to the outer surface of the first cylinder 72, and an arc groove 76 is provided on the outer surface of the rotating plate 75. An auxiliary plate 78 is slidably connected inside the arc groove 76. The third slider 74 is driven to slide inside the threaded groove 73 by moving the rotating shaft 4 downward. During the sliding process of the third slider 74, the first cylinder 72 is rotated and the rotating plate 75 is driven to rotate.

[0042] By rotating the shape of the arc groove 76 and the shape of the vertical groove 77 on the plate 75, the auxiliary plate 78 is scraped on the inner wall of the particle separation filter cartridge 5. The scraping of the auxiliary plate 78 gathers the particles precipitated or captured inside the particle separation filter cartridge 5, making it easier to clean. This helps to maintain the filtration efficiency of the particle separation filter cartridge 5 and ensure the long-term and effective operation of the filtration system. When cleaning the particle separation filter cartridge 5, the particles are gathered by scraping with the auxiliary plate 78, which can complete the cleaning work more quickly and thoroughly, thereby improving work efficiency.

[0043] A vertical groove 77 is provided at the bottom of the inner wall of the hollow column 71, a bottom plate 79 is movably connected to the bottom of the particle separation filter cartridge 5, a second spring 710 is fixedly connected to the bottom of the bottom plate 79, and one end of the second spring 710 away from the bottom plate 79 is fixedly connected to the inner wall of the bottom of the bottom cover 8, a connecting column 711 is fixedly connected to the outer surface of the rotating shaft 4, and a round cover 712 is fixedly connected to the outer surface of the bottom end of the connecting column 711, and a second cylinder 713 is slidably connected to the inside of the bottom plate 79, and a square groove 716 is provided on the inner wall of the second cylinder 713, which penetrates the second cylinder 713 and is opened to the inside of the bottom plate 79, and an inclined block 714 and a square block 715 are slidably connected to the inside of the square groove 716, and the square block 715 is connected to the inside of the square groove 716. A return spring is fixedly connected between the square grooves 716, the bottom of the hollow column 71 is fixedly connected to the bottom inner wall of the particle separation filter cartridge 5, the first cylinder 72 passes through the hollow column 71 and is rotatably connected to the top of the inner wall of the hollow column 71, the end of the third slider 74 away from the threaded groove 73 is fixedly connected to the outer surface of the bottom end of the rotating shaft 4, the bottom of the auxiliary plate 78 slides inside the vertical groove 77, the end of the auxiliary plate 78 close to the rotating shaft 4 slides inside the arc groove 76, the bottom of the end of the auxiliary plate 78 away from the rotating shaft 4 is close to the bottom inner wall of the particle separation filter cartridge 5, the bottom of the second cylinder 713 is fixedly connected to the bottom inner wall of the bottom cover 8, and the top of the end of the inclined block 714 that is not located in the square groove 716 is provided with an inclined surface.

[0044] The auxiliary plate 78 is driven to scrape the captured particles inside the particle separation filter cartridge 5 by the downward movement of the rotating shaft 4, and the connecting column 711 and the round cover 712 are driven to move downward. When the connecting column 711 moves downward, it touches the inclined block 714. Through the action of the reset spring installed on the inner wall of the square block 715 and the square groove 716, the inclined block 714 drives the square block 715 to move into the square groove 716, and the connecting column 711 moves into the second cylinder 713, so that the square block 715 and the inclined block 714 are respectively located in the bottom plate 79 and in the second cylinder 713.

Regular cleaning of particulate matter can reduce its accumulation in the particle separation filter cartridge 5, extend the service life of the particle separation filter cartridge 5, reduce the frequency of maintenance and replacement of the particle separation filter cartridge 5, and reduce the cost of use.

[0045] The following is the entire working process and working principle of the above embodiment:

[0046] First, connect the water pipe to the top of the particle separation filter cartridge 5. When water passes through the water purifier, it will flow into the particle separation filter cartridge 5. In the process of water flowing through the particle separation filter cartridge 5, the particle separation filter cartridge 5 will play a filtering role, separating and capturing particles in the water (such as mud, rust, particulate matter, etc.), which helps to improve the water purification effect and make the water cleaner and more transparent. When the impurities separated and captured inside the particle separation filter cartridge 5 are too much, they are deposited at the bottom of the particle separation filter cartridge 5, and the efficiency of filtering water quality gradually decreases. The user starts the electric telescopic rod, and the electric telescopic rod drives the rotating shaft 4 to move downward when it is extended. The rotating shaft 4 moves downward and drives the third slider 74 to slide downward inside the thread groove 73. The third slider 74 squeezes the inner wall of the thread groove 73 to make the first cylinder 72 rotate slightly. When the first cylinder 72 rotates, it drives the rotating plate 75 to rotate slightly. When the rotating plate 75 rotates, the auxiliary plate 78 moves. Through the arc groove 76 and the vertical groove 77 The auxiliary plate 78 can only move horizontally due to the limitation. Since the bottom of the end of the auxiliary plate 78 away from the rotating shaft 4 is close to the bottom inner wall of the particle separation filter cartridge 5, the auxiliary plate 78 scrapes the impurities deposited at the bottom of the particle separation filter cartridge 5 toward the bottom center of the particle separation filter cartridge 5 when it moves, and drives the third slider 74 to slide inside the threaded groove 73 by moving the rotating shaft 4 downward. During the sliding process of the third slider 74, the first cylinder 72 rotates and drives the rotating plate 75 to rotate. The shape of the arc groove 76 and the shape of the vertical groove 77 on the rotating plate 75 enable the auxiliary plate 78 to scrape the inner wall of the particle separation filter cartridge 5. The scraping of the auxiliary plate 78 gathers the particles precipitated or captured inside the particle separation filter cartridge 5, making it easier to clean. This helps to maintain the filtration efficiency of the particle separation filter cartridge 5 and ensure the long-term and effective operation of the filtration system. When cleaning the particle separation filter cartridge 5, the particles are gathered by scraping the auxiliary plate 78, so that the cleaning work can be completed more quickly and thoroughly, thereby improving work efficiency.

[0047] At the same time, the rotating shaft 4 moves downward while driving the connecting column 711 to move downward. When the connecting column 711 moves downward, it drives the round cover 712 to move downward, and the connecting column 711 moves toward the inside of the second cylinder 713. When the bottom of the connecting column 711 touches the inclined surface of the inclined block 714 and squeezes it, the inclined block 714 moves toward the inside of the square groove 716 under the squeezing force. In the initial state, the two ends of the square block 715 are respectively located inside the bottom plate 79 and inside the second cylinder 713. At this time, the square block 715 blocks the bottom plate 79 to prevent the gravity of the water from driving the bottom plate 79 to move downward to open the opening at the bottom of the particle separation filter cartridge 5 when filtering water inside the particle separation filter cartridge 5, thereby avoiding leakage. Ineffective filtration is now achieved. Since a reset spring is fixedly connected between the square block 715 and the square groove 716, the inclined block 714 moves to push the square block 715 into the inside of the square groove 716 and squeeze the reset spring. When the inclined block 714 pushes all the square blocks 715 into the square groove 716 of the bottom plate 79, the connecting column 711 drives the round cover 712 to continue to move downward, and the round cover 712 pushes the bottom plate 79 downward. At this time, the square block 715 does not jam the bottom plate 79, and the bottom plate 79 moves downward to squeeze the second spring 710. When the connecting column 711 and the round cover 712 are pushed to the bottom, the opening at the bottom of the particle separation filter cartridge 5 is opened, and at this time the auxiliary plate 78 pushes the impurities into the bottom plate 7 9, impurities enter the bottom cover 8, and are discharged through the discharge pipe 2, so as to clean the bottom of the particle separation filter cartridge 5. The auxiliary plate 78 is driven downward by the rotating shaft 4 to scrape the captured particles inside the particle separation filter cartridge 5, and at the same time, the connecting column 711 and the round cover 712 are driven downward. When the connecting column 711 moves downward, it touches the inclined block 714. Through the action of the reset spring installed on the inner wall of the square block 715 and the square groove 716, the inclined block 714 drives the square block 715 to move into the square groove 716, and the connecting column 711 moves into the second cylinder 713, so that the square block 715 and the inclined block 714 are respectively located in the bottom plate 79 and the second cylinder In 713, the downward movement of the round cover 712 will press the bottom plate 79 downward, so that there is an opening at the bottom of the particle separation filter cartridge 5. The auxiliary plate 78 scrapes the particulate matter into the bottom cover 8 to clean it, which can effectively remove the particulate matter from the inside of the particle separation filter cartridge 5, keep the inner surface of the particle separation filter cartridge 5 clean, improve the contact efficiency between the particles and water, and then improve the filtration efficiency. Regular cleaning of particulate matter can reduce its accumulation in the particle separation filter cartridge 5, extend the service life of the particle separation filter cartridge 5, reduce the frequency of maintenance and replacement of the particle separation filter cartridge 5, and reduce the cost of use. The user can clean the internal impurities of the particle separation filter cartridge 5 by pushing the electric telescopic rod up and down.

[0048] When the filter element of the particle separation filter cartridge 5 is aged or reaches a certain service life, the user needs to replace the particle separation filter cartridge 5. The user starts the electric telescopic rod, which contracts and drives the rotating shaft 4 to move upward. When the rotating shaft 4 moves upward, it drives the entire particle separation filter cartridge 5, the cleaning assembly 7 and the cover plate 61 to move upward. When the cover plate 61 moves upward, it drives the plug 62 to move upward. The plug 62 moves upward and drives the first slider 63 to move upward. Since the shapes of the first slider 63 and the second slider 67 are trapezoidal, the inclined surfaces of the first slider 63 and the second slider 67 are parallel. When the first slider 63 moves upward, it touches the second slider 67 and squeezes the second slider 67. The second slider 67 is squeezed and moves toward the inside of the cylindrical groove 64 and squeezes the first spring 66. When the first slider 63 passes the second slider 67 and leaves the water purifier housing 1, the particle separation filter cartridge 5 is disassembled. The particle separation filter cartridge 5 drives the cover plate 61 to move downward and be installed. The second slider 67 is parallel to the inclined surface of the first slider 63. The plug 62 drives the first slider 63 to touch and squeeze the second slider 67. The first slider 63 is moved to the bottom of the second slider 67 through the retractable action of the first spring 66, and the plug 62 is inserted into the water purifier housing 1. When the particle separation filter cartridge 5 is used for a long time and ages, the retractable action of the first spring 66 causes the particle separation filter cartridge 5 to move upward and drive the plug 62 to leave the water purifier housing 1, so that the particle separation filter cartridge 5 can be pushed out of the water purifier housing 1 by simple movement, and the particle separation filter cartridge 5 can be easily replaced. Users can easily replace the particle separation filter cartridge 5 by themselves without the need for professionals or maintenance services, which reduces the cost and difficulty of maintenance and repair, improves the convenience of use, and saves the time of replacing the filter element.
