Description

[0046] See also Figures 1 to 18, a filter element pull-out type water purifier, comprising a filter element housing 1, a core barrel 11 is sleeved in the filter element housing 1, and mesh leakage ports 12 are opened on the outer sides of both ends of the core barrel 11, and a two-way liquid spraying assembly 2 is arranged inside the filter element housing 1, and the two-way liquid spraying assembly 2 comprises a driving motor 21, and the driving motor 21 is movably connected to the left inner wall of the core barrel 11, and the output end of the driving motor 21 is fixedly connected with a screw rod 1 22 and a screw rod 23, and the threaded surface of the screw rod 23 is threadedly connected with a slider 1 24 and a slider 25, and the front and rear sides of the slider 1 24 and the slider 25 are fixedly connected with a support rod 26, and the support rod 26 is provided with four, and the four support rods 26 are symmetrically distributed in pairs, and the tops of the four support rods 26 are rotatably connected with an L-shaped movable plate 28, and the L-shaped movable plates 28 are provided with two, and the tops of the two L-shaped movable plates 28 are fixedly connected with an I-shaped spray head 29.

[0047] The outer surface of the spiral rod 23 passes through and is rotatably connected to an annular movable plate 212. Two annular movable plates 212 are provided, and the two annular movable plates 212 are respectively sleeved on the inner walls of the left and right ends of the core barrel 11. The outer surface of the driving motor 21 is fixedly connected to the top left side of the annular movable plate 212.

[0048] A fixing plate 27 is fixedly connected between the inner sides of the tops of the four support rods 26 , and two fixing plates 27 are provided, and the two fixing plates 27 are symmetrically distributed.

[0049] The tops of the slider 1 24 and the slider 2 25 are both fixedly connected with a white vinegar liquid tank 210 , and a drainage tube 1 211 is inserted through the left side of the white vinegar liquid tank 210 , and the output end of the drainage tube 1 211 is inserted through the top of the I-shaped spray head 29 .

[0050] In view of the prior art, the filter element water purifier filters impurities in unfiltered tap water by filtering through the core tube 11 and the mesh water leakage port 12 by self-priming water flow. This method will not only cause scale and bacteria residues to appear on the surface of the core tube 11 in contact with the filter element mesh, but also the mesh water leakage port 12 at both ends of the core tube 11 will accumulate excessive residual heavy metal substances after being in contact with the unfiltered water source for a long time, resulting in rust and odor adhesion at both ends of the core tube 11, and then the problem of excessive heavy metal content in drinking water and increased drinking water safety hazards will occur. In this application, a two-way liquid spraying assembly 2 is set. When in use, first, power is turned on to drive the output shaft of the driving motor 21 to rotate, and then the fixedly connected spiral rod 1 22 and the spiral rod 23 are driven to rotate. Rotate, and make the spiral rod 23 drive the slider 1 24 to move leftward, then make the slider 1 24 drive the support rod 26 and the fixed plate 27, the L-shaped movable plate 28, the white vinegar liquid tank 210 and the drainage pipe 1 211 to move leftward, and then make the L-shaped movable plate 28 drive the I-shaped spray head 29 to move leftward, so that the I-shaped spray head 29 can perform a mobile spraying white vinegar dilution operation on the bacterial scale attached to the surface of the core barrel 11, avoid the problem of excessive accumulation of residual bacterial scale, causing the filter blockage on the surface of the core barrel 11, reduce the possibility of bacteria causing secondary pollution to the tap water being filtered, improve the efficiency of the core barrel 11 in filtering water sources, enhance the strength of the core barrel 11 in aseptic filtering of water sources, and ensure the normal use of the water filtering process;

[0051] Synchronously, the spiral rod 23 rotates to drive the slider 25 to move rightward, and the slider 25 drives the symmetrically arranged support rod 26 and fixed plate 27, L-shaped movable plate 28, white vinegar liquid tank 210 and drainage tube 1 211 to move rightward, and then the L-shaped movable plate 28 drives the I-shaped spray head 29 to move rightward, so that the I-shaped spray head 29 arranged on the top of the slider 25 can perform a mobile spraying white vinegar dilution operation on the surface of the core barrel 11, thereby avoiding incomplete dilution of bacteria and dirt on the surface of the core barrel 11, causing secondary pollution of the core barrel 11, increasing the dilution force of dirt on the surface of the core barrel 11, enhancing the sterilization and descaling effect of the core barrel 11, and ensuring the normal pollution-free filtration of tap water.

[0052] It should be noted that since the slider 2 25 and the slider 1 24 are symmetrically arranged, while the slider 1 24 indirectly drives the I-shaped spray head 29 to the left to spray white vinegar to dilute the bacteria, the slider 2 25 can also indirectly drive the I-shaped spray head 29 to the right to perform the same effect of spraying white vinegar to dilute the surface of the core tube 11, thereby achieving a complete sterilization and descaling effect on the outer surface of the core tube 11.

[0053] This solution provides a two-way liquid spraying assembly 2. Under the action of the synchronous movement of the slider 1 24 and the slider 2 25, one left and one right, the two I-shaped spray heads 29 can be indirectly driven to perform a two-way mobile spraying of white vinegar dilution to dissolve the bacteria and dirt attached to the surface of the core tube 11, thereby avoiding the phenomenon that the bacterial impurities accumulated on the surface of the core tube 11 due to long-term filtration cannot be removed, causing the water source filtration to be blocked, affecting the water quality safety, enhancing the accuracy of the filtration on the surface of the filter screen of the core tube 11, improving the quality of the water source after filtration, and ensuring the normal filtration of the filter element water purifier.

[0054] like Figures 5 to 9 As shown, a corner assembly 3 is provided inside the filter element housing 1;

[0055] The corner assembly 3 includes a cylinder 31, the outer surface of which is rotatably connected to the top of the fixed plate 27, and the output end of the cylinder 31 is rotatably connected to a concave rod 33, and the front and rear sides of the concave rod 33 are fixedly connected to the L-shaped movable plate 28.

[0056] The outer surface of the spiral rod 1 22 is threadedly connected with a concave rod 2 36, the left end of the spiral rod 23 penetrates and is rotatably connected with a spur gear 32, the bottom of the spur gear 32 is meshedly connected with a ring gear 34, and the ring gear 34 is fixedly connected to the inner wall of the left end of the core barrel 11, and an arc groove 35 is opened between the left and right sides of the core barrel 11, and the left and right ends of the spiral rod 23 penetrate the core barrel 11 and are slidably connected to the inside of the arc groove 35.

[0057] By setting the corner assembly 3, when in use, the I-shaped spray head 29 on the top of the slider 24 can be moved to the left to the left end surface of the core barrel 11, and the bacteria on the surface of the core barrel 11 are diluted. At this time, the output end of the cylinder 31 on the top of the slider 24 can be driven to extend to the left, and the concave rod 33 is pushed to rotate around the top axis of the support rod 26, and the concave rod 33 pushes the L-shaped movable plate 28 to rotate, and then the L-shaped movable plate 28 pushes the I-shaped spray head 29 to rotate, and the slider is moved. After the nozzle of the I-shaped spray head 29 at the top of the core barrel 11 is rotated to be aligned with the left end face of the core barrel 11, the I-shaped spray head 29 can be used to spray the white vinegar dilution liquid on the left end face of the core barrel 11 in a mobile manner, so as to avoid the problem of excessive impurities attached to the left end face of the core barrel 11 due to long-term contact with tap water, thereby reducing the interference of residual impurities and dirt on the water filtration of the core barrel 11, improving the efficiency of the clean water filtration of the core barrel 11, increasing the strength of odor-free filtration of the water source, and ensuring the normal use of the water purification filtration process;

[0058] After the I-shaped spray head 29 at the top of the slider 25 moves to the right to be flush with the right end face of the core barrel 11, the cylinder 31 at the top of the slider 25 pushes the concave rod 1 33 to rotate, so that the concave rod 1 33 at the top of the slider 25 indirectly pushes the I-shaped spray head 29 to rotate. After the nozzle of the I-shaped spray head 29 at the top of the slider 25 rotates to be aligned with the right end face of the core barrel 11, the I-shaped spray head 29 can perform a mobile spraying operation of white vinegar dilution on the right end face of the core barrel 11, avoiding the problem that the scale impurities attached to the right end face of the core barrel 11 cannot be completely diluted, further strengthening the sterilization of the right end face of the core barrel 11, and ensuring the normal high-quality filtration of the water source;

[0059] At the same time, under the action of the continuous rotation of the spiral rod 22, the spiral rod 22 drives the concave rod 2 36 to rotate, and drives the concave rod 2 36 to move to the right. After the two extending ends on the right side of the concave rod 2 36 are plugged into the left recessed part of the spur gear 32, the concave rod 2 36 drives the spur gear 32 to rotate under the action of the continuous rotation of the concave rod 2 36. Since the ring gear 34 is fixed in the inner wall of the left end of the core barrel 11, when the spur gear 32 rotates, it can drive the spiral rod 1 22, the spiral rod 23 and the driving motor 21 and the concave rod 1 33 to rotate along the tooth groove of the ring gear 34, and the spiral rod 23 drives the annular movable plate 212 to rotate along the inside of the arc groove 35, and at the same time, the spiral rod The second slider 23 drives the slider 1 24 and the slider 2 25 to rotate, and the slider 1 24 and the slider 25 drive the support rod 26 and the fixed plate 27, the L-shaped movable plate 28, the cylinder 31 and the spur gear 32 to rotate, so that the L-shaped movable plate 28 drives the I-shaped spray head 29 to rotate, and further enables the I-shaped spray head 29 to perform a rotary spraying operation of white vinegar dilution on the two end surfaces of the core barrel 11, thereby avoiding the problem that the I-shaped spray head 29 cannot sterilize the bottom of the two ends of the core barrel 11 due to the limitation of the spraying area, causing the problem of bacterial growth and spread at the bottom of the core barrel 11, reducing the corrosion of bacteria on the two ends of the core barrel 11, improving the efficiency of sterilization and filtration of the core barrel 11, increasing the range of spraying sterilization of the core barrel 11, and ensuring the normal use of the complete sterilization process of the core barrel 11.

[0060] It should be noted that the rotational movement of the annular movable plate 212 is achieved after the two I-shaped spray heads 29 move and rotate to align with the two end surfaces of the core barrel 11, and then the annular movable plate 212 is synchronously driven to rotate, thereby increasing the spraying and sterilization area and force of the two I-shaped spray heads 29 on the core barrel 11, thereby completing the sterilization process at both ends of the core barrel 11.

[0061] By setting the corner assembly 3, the present solution can indirectly drive the I-shaped spray head 29 to perform a rotary spraying operation of dissolving the bacteria and dirt attached to the two ends of the core barrel 11 with the white vinegar dilution solution under the action of the continuous rotation of the spur gear 32 and the concave rod 33, so as to avoid excessive accumulation of bacteria and impurities at the two ends of the core barrel 11 for a long time, resulting in corrosion at the two ends of the core barrel 11 and pungent odor, causing the water source to become rancid after filtration and the water source cannot be drunk, thereby improving the safety of sterilization filtration at the two ends of the core barrel 11, enhancing the strength of high-quality filtration of the water source, and ensuring the normal use of the filter element water purifier for safe filtration.

[0062] like Figures 10 to 12 As shown, a heavy metal removal component 4 is disposed inside the filter housing 1;

[0063] The heavy metal removal component 4 includes a T-shaped slide 41, the top of the T-shaped slide 41 is slidably connected to the inner wall of the filter element housing 1, the outer surface of the T-shaped slide 41 is penetrated by a chelating softener box 42, and the bottom of the T-shaped slide 41 is penetrated by the outer surface of the spiral rod 23.

[0064] The left and right sides of the chelating softener box 42 are penetrated and plugged with drainage tube 2 43 and drainage tube 3 44, and the output ends of drainage tube 2 43 and drainage tube 3 44 are penetrated and plugged into the top of drainage tube 1 211. The top of the filter element housing 1 is penetrated and plugged with elastic telescopic tube 1 45 and elastic telescopic tube 2 46, and the bottom of the elastic telescopic tube 1 45 is penetrated and plugged from the top of the T-shaped slide 41 to the right side of the T-shaped slide 41. A delivery hose 47 is penetrated and plugged between the left and right sides of the two white vinegar liquid tanks 210, and the top of the delivery hose 47 is penetrated and plugged with the output end of the elastic telescopic tube 1 45, and the bottom of the elastic telescopic tube 2 46 is penetrated and plugged from the top of the T-shaped slide 41 to the inner top wall of the T-shaped slide 41, and the output end of the elastic telescopic tube 2 46 is penetrated and plugged into the top of the chelating softener box 42.

[0065] By setting up the heavy metal removal component 4, when working, the chelating agent in the chelating softening agent box 42 can be transferred to the drainage pipe 2 43 and the drainage pipe 3 44 under the transmission action of the diversion pump built in the chelating softening agent box 42, and then the drainage pipe 2 43 and the drainage pipe 3 44 will drain the transferred chelating agent into the drainage pipe 1 211, so that the diversion pump built in the white vinegar liquid box 210 will transport the white vinegar dilution liquid to the drainage pipe 1 211. At the same time, the drainage pipe 2 43 and the drainage pipe 3 44 can The white vinegar diluent after drainage in the drainage tube 211 is sprayed with a chelating agent to soften and remove heavy metals, thereby preventing residual hard heavy metal contaminants from adhering to the core tube 11 and the mesh water leakage port 12 after the I-shaped spray head 29 sprays liquid for sterilization, causing heavy metal corrosion of the core tube 11 and the mesh water leakage port 12, reducing the possibility of undrinkable water, improving the efficiency of water softening and filtration, strengthening the sterilization and descaling effect of the white vinegar diluent, and ensuring the normal safe filtration of the water source.

[0066] It should be noted that the chelating agent removes heavy metals only after the I-shaped spray head 29 rotates to align with the two end surfaces of the core barrel 11, and then the chelating agent is sprayed into the white vinegar diluent, and the heavy metal pollutants on the surface of the core barrel 11 and the mesh water leakage port 12 are simultaneously diluted, thereby ensuring that the core barrel 11 and the mesh water leakage port 12 are normally filtered without pollution;

[0067] At the same time, while the spur gear 32 indirectly drives the I-shaped spray head 29 to rotate, the T-shaped slide plate 41 can be synchronously driven to drive the chelating softener box 42, drainage pipe 2 43 and drainage pipe 3 44 to rotate along the inner wall of the filter element housing 1, thereby ensuring the chelating agent energy demand of the I-shaped spray head 29, and assisting the I-shaped spray head 29 to complete the heavy metal removal process of the core barrel 11 and the mesh leakage port 12.

[0068] By setting up the heavy metal removal component 4, the present scheme can realize the softening and heavy removal operation of the white vinegar dilution in the drainage tube 1 211 by spraying the chelating agent under the action of the continuous supply of the chelating agent by the drainage tube 2 43 and the drainage tube 3 44, so as to avoid the residual heavy metal pollutants adhering to the surface of the core tube 11 and the mesh leakage port 12 after the white vinegar diluent is sterilized, causing the heavy metal corrosion phenomenon of the mesh leakage port 12, resulting in the problem of excessive heavy metal content in the water source, reducing the possibility of the water source being undrinkable, improving the high efficiency of the softening filtration of the mesh leakage port 12, increasing the strength of the sterilization and descaling of the white vinegar diluent, and ensuring the normal sterilization and filtration of the water source.

[0069] like Figures 13 to 18 As shown, a spray speed regulating component 5 is disposed inside the filter housing 1;

[0070] The injection speed regulating assembly 5 comprises a crank sheave 51, the left side of the crank sheave 51 is fixedly connected to the screw rod 23, the interior of the crank sheave 51 is slidably connected to a slide rod 52, the right end of the slide rod 52 is fixedly connected to a piston rod 53, the piston end of the piston rod 53 is slidably and sealingly connected to a blow cylinder 54, and the output end of the blow cylinder 54 is penetrated and plugged with a pressure tank 55.

[0071] The output end of the pressure tank 55 is penetrated and plugged with a hose 56, the outer surface of which is penetrated and plugged with the annular movable plate 212, the output end of which is penetrated and plugged with the front side of the drainage tube 211, the right side of the input end of the hose 56 is penetrated and plugged with a shunt tube 57, the outer surface of which is penetrated and plugged with the annular movable plate 212, and the output end of which is penetrated and plugged with the rear side of the drainage tube 211.

[0072] By setting up the spray speed regulating component 5, when working, the screw rod 23 can drive the crank groove wheel 51 to rotate under the action of the continuous rotation force of the screw rod 23, so that the crank groove wheel 51 drives the sleeved sliding rod 52 to move forward and backward, and the sliding rod 52 drives the piston rod 53 to move forward and backward, so that the piston rod 53 can inhale the inner cavity of the air cylinder 54, so that the inner cavity of the air cylinder 54 forms a pressure-releasing suction power, and the air cylinder 54 can suck the compressed air in the pressure tank 55, so that the pressure tank 55 can The inner cavities of the hose 56 and the shunt tube 57 perform suction and pressure operations, so that the hose 56 and the shunt tube 57 can perform suction and slow flow operations on the inside of the drainage tube 211, thereby adjusting the spray speed of the nozzle of the I-shaped spray head 29 to avoid uneven spray speed of the white vinegar diluent, resulting in impurities on the surface of the core tube 11 and the mesh leakage port 12 cannot be completely removed, thereby causing the problem of water quality deterioration, improving the efficiency of complete dissolution and sterilization of the white vinegar diluent, enhancing the strength of the core tube 11 and the mesh leakage port 12 in filtering water sources, and ensuring the normal high-quality filtration of the filter element water purifier.

[0073] It should be noted that the adjustment of the spray speed of the I-shaped spray head 29 nozzle is achieved by the continuous rotation of the crank groove wheel 51, which indirectly drives the piston rod 53 to move back and forth to generate suction power for the inner cavity of the air cylinder 54, thereby providing power support for the suction, pressure and slow flow operation of the hose 56 and the diverter pipe 57, thereby completing the adjustment of the spray speed of the I-shaped spray head 29 nozzle and assisting the I-shaped spray head 29 to complete the sterilization process of the core tube 11.
