[0019] The present application will be further described below in combination with the embodiments shown in the drawings.
[0020] Embodiment: A filter with filter core convenient to replace, such as Figures 1-4As shown, it comprises filter shell 1, drainage 2, upper shell 3, filter core body 4, positioning member 5, fixed disc 6, scraper 7, spring 8, handle 9, limiting port 10 and water inlet pipe 11, filter shell 1 is provided with two, two filter shell 1 bottom water outlet is connected between drainage 2, for discharging filtered water, the top of the two filter shell 1 is connected with upper shell 3 through screw thread, the inside of filter shell 1 is placed with filter core body 4, the top of filter core body 4 is connected with upper shell 3 through clamping, convenient to disassemble and replace, the inner lower part of filter shell 1 is connected with fixed disc 6, the bottom of fixed disc 6 is provided with limiting port 10, the lower part of filter core body 4 is connected with positioning member 5, positioning member 5 is composed of an elastic member and a clamping bead, when filter core body 4 is put into filter shell 1, the clamping bead of positioning member 5 is clamped in limiting port 10 on fixed disc 6, so as to realize the limiting of filter core body 4, the bottom of filter core body 4 is clamped with scraper 7, scraper 7 is located in the inside of filter shell 1 and closely adheres to the inner wall of filter shell 1, when taking out filter core body 4 upward, scraper 7 can move upward synchronously, and the dirt on the inner wall of filter shell 1 is scraped off, the bottom of scraper 7 is placed with a pad, the spring 8 is connected between the pad and the fixed disc 6, the top of the upper shell 3 is connected with the handle 9, the handle 9 is convenient to take out the filter core body 4 and the upper shell 3, the upper rear side of the filter shell 1 is communicated with the water inlet pipe 11, which is used for introducing the water to be filtered into the filter, the water inlet pipe 11 is connected by flange, which is convenient to install and disassemble.
[0021] Firstly, the water to be filtered will flow into the inside of filter shell 1 through water inlet pipe 11. In filter shell 1, filter core body 4 can retain impurities and dirt in the water on the filter core, while clean water continues to flow downward through the filter core, and finally is discharged from the water outlet at the bottom of filter shell 1 and collected and discharged through drainage 2.
[0022] The top of filter core body 4 and upper shell 3 are connected by clamping, which makes filter core body 4 easily disassembled and replaced. When the filter core needs to be replaced, the user only needs to reverse and unscrew the upper shell 3. Since the upper shell 3 and the filter core body 4 are connected by clamping, when the upper shell 3 is screwed, the filter core body 4 will rotate synchronously. At this time, the clamping bead in the positioning member 5 will rotate with the bottom of the fixed disc 6. When the upper shell 3 is completely unscrewed, the positioning member 5 will no longer be fixed by the limiting port 10. At this time, the user can hold the handle 9 and easily lift the filter core body 4 upward. In the process of lifting the filter core body 4, the scraper 7 at the bottom of the filter core body 4 will move upward synchronously. The scraper 7 closely adheres to the inner wall of the filter shell 1, so it can effectively scrape off the dirt and residues attached to the inner wall of the filter shell 1 during the movement, thereby keeping the filter shell 1 clean.
[0023] Subsequently, the user can replace the new filter core body 4. The replacement process of the filter core body 4 is also simple. When the filter core body 4 is put into the filter shell 1 and in contact with the inner wall of the fixed disc 6, the clamping beads in the positioning piece 5 are extruded, so that the elastic piece is compressed. When the filter core body 4 is completely put in, the user can rotate the upper shell 3 and tighten it. In this process, the positioning piece 5 will continue to be extruded until it rotates to the limiting port 10 on the fixed disc 6. At this time, the clamping beads in the positioning piece 5 will no longer be extruded, and will be extruded outward under the elastic force of the elastic piece, so as to be clamped in the limiting port 10 of the fixed disc 6. In this way, the positioning piece 5 realizes the limiting effect of the filter core body 4, preventing it from shaking or moving during the filtering process.
[0024] Between the pad plate at the bottom of the scraper 7 and the fixed disc 6, a spring 8 is connected. The spring 8 provides a downward elastic force for the scraper 7, so that it can tightly fit on the inner wall of the filter shell 1, thereby ensuring the effect of scraping dirt. At the same time, when the filter core body 4 is lifted, the spring 8 can also play a buffering role, reducing the friction and wear between the scraper 7 and the inner wall of the filter shell 1.
[0025] In summary, the filter with convenient replacement of filter core realizes effective filtration of water and convenient maintenance of the filter through the filtering effect of the filter core body 4, the clamping connection mode, the dirt scraping effect of the scraper 7 and the elastic force of the spring 8 and other mechanisms.
[0026] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present application. Those skilled in the art will understand that the variations of the present application will be included in the scope of the claims herein.
