Description

Technical Field

[0001] The utility model relates to the field of water purification, in particular to a self-cleaning water purification device. Background Art

[0002] Water purification equipment is a process of removing rust, silt, residual chlorine, organic matter, harmful heavy metal ions, bacteria, viruses, etc. from water by physical or chemical means through corresponding filter materials according to different final water needs. Obviously, if the water purification uses physical filtration throughout the process, no new substances will be produced or added to the water, and the properties of the water will not be changed, so it is the safest way.

[0003] Most of the current water purification devices filter water through a filter. When the filter is clogged, it needs to be disassembled, cleaned and replaced, which is troublesome. Therefore, it is necessary to design a self-cleaning water purification device that can clean and drain the filter without disassembling it. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a self-cleaning water purification device to solve the technical problem that when the filter screen is blocked, it needs to be disassembled, cleaned and replaced, which is troublesome to operate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning water purification device, comprising a device body, a rotating assembly is installed inside the device body, the rotating assembly includes a rotary blade, the rear end of the rotary blade is connected to a support rod, both ends of the support rod are installed with slip rings, the center position of the support rod is connected to a brush seat via a connecting rod, and a brush is installed on the brush seat.

[0006] By adopting the above technical solution, automatic cleaning is possible, and users do not need to frequently disassemble and manually clean the filter, which can greatly simplify maintenance work and save time and labor. The rotating component can automatically rotate under the impetus of the water flow, so that the brush can continuously clean the filter, thereby avoiding the filter from being blocked due to long-term accumulation of impurities and reducing the need for manual cleaning.

[0007] Furthermore, a filter screen is installed inside the device body, a slide rail with an annular structure is installed on one side of the filter screen, the slide rail is used for the sliding of the slip ring, and flanges are installed on both sides of the device body.

[0008] By adopting the above technical solution, the filter is responsible for intercepting impurities in the water to ensure the cleanliness of the water. The design of the filter is required to effectively filter out fine particles while maintaining sufficient water flow.

[0009] Furthermore, the device body is fixedly connected to the water pipe via a flange.

[0010] By adopting the above technical solution, the flange is used to fix the device body to the water pipe. This design facilitates the installation and maintenance of the water purification device, while also ensuring the sealing and stability between the device and the water pipe.

[0011] Furthermore, a sewage pipe is connected to the top of the device body, and the sewage pipe is "Y"-shaped. The bottom end of the sewage pipe is connected to a first branch pipe and a second branch pipe respectively, and the first branch pipe and the second branch pipe are connected to the device body respectively. The connection positions of the first branch pipe and the second branch pipe with the device body are respectively located on both sides of the filter net.

[0012] By adopting the above technical solution, during the cleaning process, impurities scraped from the filter can flow to the drain pipe through the first branch pipe and the second branch pipe, and then be discharged out of the device. Since some impurities will run to the other side of the filter after brushing, the "Y"-shaped structure simplifies the drain channel, so that the sewage on both sides of the filter can be discharged at the same time, which not only balances the drain pressure, but also prevents damage to the filter during draining, which helps to improve the drain efficiency.

[0013] Furthermore, a fixing block is installed on the outer wall of the device body, a threaded rod is vertically threadedly installed on the fixing block, the threaded rod penetrates the outer wall of the device body and contacts the slip ring, and a knob is fixed on the top of the threaded rod.

[0014] By adopting the above technical solution, the fixing block provides a fixing point for the threaded rod, thereby enhancing the structural stability of the entire device. By installing the fixing block on the outer wall of the device body, a simple way is provided for limiting and fixing the rotating component.

[0015] Furthermore, the brush is rectangular, the length of the brush is smaller than the diameter of the filter, and the brush fits the filter.

[0016] By adopting the above technical solution, it is helpful to match and cover the surface of the filter. The rectangular brush can better fit the curved edge of the circular filter, thereby improving the cleaning efficiency.

[0017] Furthermore, the slip ring is matched with the slide rail, and the outer diameter of the slip ring is the same as the inner diameter of the slide rail.

[0018] By adopting the above technical solution, the precise matching relationship between the slip ring and the slide rail ensures that the rotating assembly can rotate smoothly and unhindered inside the device body. This design reduces friction and wear and increases the service life of the device.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model provides a rotating assembly. When cleaning the filter, the user only needs to open the sewage pipe to allow the water to flow. The water flow will stir the rotary blades to rotate, and the rotary blades drive the support rods to rotate, so that the support rods rotate on the slide rails through the slip rings, and then drive the brushes to rotate. The brushes fit the filter and can scrape the impurities on the surface of the filter to make the impurities fall off. At this time, under the action of water pressure, the impurities and sewage pass through the first branch pipe and the second branch pipe, and are finally discharged through the sewage pipe. There is no need for staff to disassemble and clean, which improves the automation of cleaning and has a good cleaning effect.

[0021] 2. The utility model installs a fixing block on the outer wall of the device body. When in normal use, the user rotates the knob to move the threaded rod downward, so that the end of the threaded rod abuts against the slip ring, limiting the slip ring, thereby fixing the rotating component, and water flows through the filter screen for normal water use.

[0031] See also Figure 1 , Figure 2 , a filter screen 11 is installed inside the device body 1, and a slide rail 12 of an annular structure is installed on one side of the filter screen 11. The slide rail 12 is used for the sliding ring 53 to slide. Flanges 3 are installed on both sides of the device body 1. The filter screen is responsible for intercepting impurities in the water to ensure the cleanliness of the water. The design of the filter screen requires that it can effectively filter out fine particles while maintaining sufficient water flow. The slide rail of the annular structure provides a sliding track for the sliding ring 53 in the rotating component 5, so that the rotating component can rotate smoothly, thereby driving the brush 56 to clean the filter screen. The sliding ring slides on the slide rail, and the support rod 52 is connected to the rotating component 5 through the sliding ring, and the rotational power is transmitted to the brush 56 to realize automatic cleaning of the filter screen.

Since some impurities will run to the other side of the filter after brushing, the "Y"-shaped structure simplifies the sewage discharge channel, so that the sewage on both sides of the filter 11 can be discharged at the same time, which can not only balance the sewage discharge pressure, but also prevent the filter from being damaged during sewage discharge, which is helpful to improve the sewage discharge efficiency and ensure that during the cleaning process of the filter 11, no matter which side the impurities fall off from, they can be effectively guided into the sewage discharge system, thereby improving the cleaning efficiency.

[0033] Embodiment 2:

[0034] See also Figure 2 The outer wall of the device body 1 is installed with a fixing block 6, and a threaded rod 62 is installed on the fixing block 6 with a vertical thread. The threaded rod 62 penetrates the outer wall of the device body 1 and contacts the slip ring 53. A knob 61 is fixed on the top of the threaded rod 62.

[0036] See also Figure 2The slip ring 53 is matched with the slide rail 12, and the outer diameter of the slip ring 53 is the same as the inner diameter of the slide rail 12. The precise matching relationship between the slip ring 53 and the slide rail 12 ensures that the rotating component 5 can rotate smoothly and unhindered inside the device body 1. This design reduces friction and wear and increases the service life of the device. The outer diameter of the slip ring 53 is the same as the inner diameter of the slide rail 12. Such size matching allows the slip ring to slide smoothly on the slide rail while avoiding instability or offset caused by excessive clearance.

[0037] Embodiment three:

When the filter screen 11 is saturated with impurities, the user opens the sewage pipe 4 to allow the water to flow, and rotates the knob 61 in the opposite direction to make the threaded rod 62 away from the slip ring 53. The water flow will stir the rotary blade 51 to rotate, and the rotary blade 51 drives the support rod 52 to rotate, so that the support rod 52 rotates on the slide rail 12 through the slip ring 53, and then drives the brush 56 to rotate. The brush 56 fits the filter screen 11 and can scrape the impurities on the surface of the filter screen 11, so that the impurities fall off. At this time, under the action of water pressure, the impurities and sewage pass through the first branch pipe 41 and the second branch pipe 42, and are finally discharged through the sewage pipe 4.
