Description

Technical Field

[0001] This application relates to the field of water purifiers, and more particularly to a water purifier. Background Technology

[0002] Water purification is necessary in food safety production. Purified water can remove impurities, microorganisms and other harmful substances from the water, thereby avoiding food contamination caused by water quality problems and ensuring food hygiene and safety. Generally, water purifiers are equipped with activated carbon filters to purify the water.

[0003] However, traditional water purifiers require shutdown during activated carbon filter replacement, during which water purification cannot be carried out, thus preventing food production and delaying food processing efficiency. Utility Model Content

[0004] In order to ensure the efficiency of food processing without stopping the machine when replacing the activated carbon filter, this application provides a water purifier.

[0005] This application provides a water purifier that adopts the following technical solution: A water purifier includes a support base with a purification structure. The purification structure includes a first connecting cylinder and a second connecting cylinder. Multiple first connecting cylinders are fixedly connected to the support base. A second connecting cylinder is threaded to the bottom end of each first connecting cylinder. A filter element abuts between the first and second connecting cylinders. A connecting sleeve is fixedly connected between two adjacent first connecting cylinders. Two connecting pipes are fixedly connected to the connecting sleeves. One end of each connecting pipe is fixedly connected to an adjacent first connecting cylinder. A one-way valve is installed on each connecting pipe. An inlet pipe is fixedly connected to one of the connecting sleeves located on the leftmost side of the support base. One end of each of the two connecting pipes located on the rightmost side of the support base is fixedly connected to the same drain pipe. A valve block is rotatably connected inside the connecting sleeve. The valve block has a through groove inside and a limiting structure on the valve block.

[0006] By adopting the above technical solution, the valve block is rotated. When the valve block is rotated 90 degrees and then stopped, the position of the through groove changes. After the position of the through groove changes, the water flow path will change, allowing filtration through another filter element. At the same time as filtration through the other filter element, the filter element that needs to be replaced can be removed and replaced. This process does not require stopping the machine, thus enabling continuous water purification and avoiding delays in food production due to filter element replacement, thereby effectively ensuring the efficiency of food production.

[0007] Optionally, one of the positioning rings is fixedly connected to the first connecting cylinder, and another positioning ring is fixedly connected to the second connecting cylinder. One end of the filter element is engaged with one of the positioning rings, and the other end of the filter element is engaged with the other positioning ring.

[0008] By adopting the above technical solution, during the installation of the filter element, one end of the filter element can be engaged with the positioning ring on the second connecting cylinder, thereby achieving the positioning of the filter element. After installation, the other end of the filter element will be engaged with another positioning ring on the first connecting cylinder, thereby achieving further positioning of the filter element.

[0009] Optionally, the outer side of the second connecting cylinder is provided with a plurality of protrusions, which are arranged in a circumferential array about the middle of the second connecting cylinder.

[0010] By adopting the above technical solution, multiple protrusions can prevent hand slippage during the rotation of the second connecting cylinder, thereby effectively improving the stability of use.

[0011] Optionally, the transverse cross-section of the through groove has an L-shaped structure, and the top of the valve block extends to the outside of the connecting sleeve.

[0012] By adopting the above technical solution, the path of water flow can be changed when the channel is rotated 90 degrees.

[0013] Optionally, the limiting structure includes a connecting block and an insert block. The connecting block is fixedly connected to the valve block, and the insert block is slidably connected to the connecting block. The connecting sleeve is provided with two slots, and the bottom end of the insert block engages with one of the slots.

[0014] By adopting the above technical solution, when the valve block needs to be rotated, the insert block can be pulled. When the insert block is not engaged with one of the slots, the valve block can be rotated. Since the connecting block and the valve block are perpendicular, the lever arm can be increased, thus making it easier to rotate the valve block. When the valve block is rotated exactly 90 degrees, the insert block will engage with the other slot, thereby achieving precise control of the valve block rotation angle and effectively improving the stability of use.

[0015] Optionally, a spring is sleeved on the outside of the insert block, with one end of the spring resting on the connecting block and the other end of the spring abutting against the insert block.

[0016] By adopting the above technical solution, when the end of the plug is facing the slot, the spring will extend and drive the plug to move automatically toward the slot, and under the action of the spring force, the plug and the slot will be more firmly engaged.

[0017] Optionally, the vertical cross-section at the bottom of the insert block is trapezoidal, and the vertical cross-section at the top of the insert block is convex.

[0018] By adopting the above technical solution, it is not only convenient to pull the plug, but also to guide the movement of the plug during the engagement process between it and the slot.

[0019] Optionally, the valve block is provided with a blocking structure, the blocking structure including a connecting shaft and a connecting plate. The bottom end of the valve block is fixedly connected to the connecting shaft, and the connecting shaft is rotatably connected to the connecting sleeve. The bottom end of the connecting shaft is fixedly connected to the connecting plate, and the connecting plate is provided with two protrusions, one of which abuts against the first connecting cylinder.

[0020] By adopting the above technical solution, during the rotation of the valve block, the valve block will drive the connecting shaft to rotate, the connecting shaft will drive the connecting disc to rotate, and the rotation of the connecting disc will drive the two protrusions to rotate. Before the connecting disc rotates, one of the protrusions blocks one of the second connecting cylinders, while the other protrusion blocks the other second connecting cylinder. When the connecting disc rotates 90 degrees, one of the protrusions no longer blocks one of the second connecting cylinders, while the other protrusion blocks the other second connecting cylinder. Therefore, when it is necessary to rotate one of the second connecting cylinders to replace its internal filter element, the other second connecting cylinder cannot be rotated, thus avoiding incorrect rotation and effectively improving the stability of use.

[0021] In summary, this application includes at least one of the following beneficial technical effects: When the filter element needs to be replaced, rotate the valve block 90 degrees. Rotating the valve block 90 degrees will change the position of the through groove, and the water flow path will change after the position of the through groove changes. At this time, it can be filtered through another filter element. While filtering through another filter element, the filter element that needs to be replaced can be removed and replaced. This process does not require stopping the machine, thus enabling continuous water purification and avoiding delays in food production due to filter element replacement, thereby effectively ensuring the efficiency of food production. Setting multiple filter cartridges can improve the water purification effect. When replacing the filter cartridge, the second connecting tube can be twisted off from the first connecting tube, and the filter cartridge will be removed together with the second connecting tube, thus realizing quick disassembly of the filter cartridge and facilitating filter cartridge replacement. During the rotation of the valve block, the valve block drives the connecting shaft to rotate, which in turn drives the connecting disc to rotate. The rotation of the connecting disc causes two protrusions to rotate. Before the connecting disc rotates, one protrusion blocks one of the second connecting cylinders, while the other protrusion blocks the other second connecting cylinder. When the connecting disc rotates 90 degrees, one of the protrusions no longer blocks one of the second connecting cylinders, while the other protrusion blocks the other second connecting cylinder. Therefore, when it is necessary to rotate one of the second connecting cylinders to replace its internal filter element, the other second connecting cylinder cannot be rotated, thus avoiding incorrect rotation and effectively improving the stability of use.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a water purifier. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A water purifier includes a support base 1, on which a purification structure 2 is provided.

[0026] In use, the water delivery pipe can be connected to the inlet pipe 206 and the drain pipe 212 respectively, and then the water enters the inside of the inlet pipe 206. The water will then flow into the inside of one of the connecting sleeves 207. During the flow, the water can be guided through the through groove 209 and flow into the inside of one of the first connecting cylinders 201. Then the water will be purified through the filter element 205. Finally, it will flow from the inside of one of the connecting pipes 210 into the inside of the next connecting sleeve 207 for the next purification. The water purified through multiple times will finally be discharged from the drain pipe 212, thus achieving multiple purification of water and effectively improving the water purification effect. When filter element 205 needs to be replaced, first ensure that the insert block 302 is not locked to the slot 304. Then, rotate valve block 208 90 degrees. This rotation will change the position of through groove 209, altering the water flow path. Water will then flow into the other first connecting cylinder 201 and be filtered through another filter element 205. Simultaneously, the filter element 205 that needs replacement can be removed and replaced without stopping the machine. This enables continuous water purification, preventing food production delays caused by filter element 205 replacement and effectively ensuring production efficiency. When replacing filter element 205, the second connecting cylinder 202 can be unscrewed from the first connecting cylinder 201. Multiple protrusions 203 prevent hand slippage during rotation of the second connecting cylinder 202, thus improving stability. Filter element 205 is removed along with the second connecting cylinder 202, enabling quick disassembly and easy replacement.

[0027] Reference Figure 3 and Figure 4 One of the positioning rings 204 is fixedly connected to the first connecting cylinder 201, and another positioning ring 204 is fixedly connected to the second connecting cylinder 202. One end of the filter element 205 is engaged with one of the positioning rings 204, and the other end of the filter element 205 is engaged with the other positioning ring 204.

[0028] During the installation of filter element 205, filter element 205 can be taken into the interior of the second connecting cylinder 202, and one end of filter element 205 can be engaged with the positioning ring 204 on the second connecting cylinder 202 to achieve positioning of filter element 205. Then, the second connecting cylinder 202 is twisted onto the first connecting cylinder 201. When the second connecting cylinder 202 and the first connecting cylinder 201 are in contact, one end of filter element 205 will be in contact with the second connecting cylinder 202, and the other end will be in contact with the first connecting cylinder 201. At this time, the installation of filter element 205 is completed. After the installation is completed, the other end of filter element 205 will be engaged with another positioning ring 204 on the first connecting cylinder 201 to achieve further positioning of filter element 205.

[0029] Reference Figure 2 and Figure 4 The limiting structure 3 includes a connecting block 301 and an insert block 302. The connecting block 301 is fixedly connected to the valve block 208, and the insert block 302 is slidably connected to the connecting block 301. The connecting sleeve 207 is provided with two slots 304. The bottom end of the insert block 302 is engaged with one of the slots 304. A spring 303 is sleeved on the outside of the insert block 302. One end of the spring 303 is located on the connecting block 301, and the other end of the spring 303 abuts against the insert block 302. The vertical cross-section of the bottom end of the insert block 302 is trapezoidal, and the vertical cross-section of the top end of the insert block 302 is convex.

[0030] The engagement between the insert 302 and the slot 304 prevents the valve block 208 from rotating. When the valve block 208 needs to be rotated, the insert 302 can be pulled, causing the spring 303 to retract. When the insert 302 is not engaged with one of the slots 304, the valve block 208 can be rotated. Since the connecting block 301 and the valve block 208 are perpendicular, the lever arm is increased, making it easier to rotate the valve block 208. When the valve block 208 has rotated exactly 90 degrees, the spring 303 will extend, causing the insert 302 to engage with the other slot 304, thereby achieving precise control of the rotation angle of the valve block 208 and effectively improving the stability of use.

[0031] Reference Figure 3 and Figure 4 The valve block 208 is provided with a blocking structure 4, which includes a connecting shaft 401 and a connecting plate 402. The bottom end of the valve block 208 is fixedly connected to the connecting shaft 401, and the connecting shaft 401 is rotatably connected to the connecting sleeve 207. The bottom end of the connecting shaft 401 is fixedly connected to the connecting plate 402, and the connecting plate 402 is provided with two protrusions 403, one of which abuts against the first connecting cylinder 201.

[0032] During the rotation of valve block 208, valve block 208 will drive connecting shaft 401 to rotate, connecting shaft 401 will drive connecting disc 402 to rotate, and connecting disc 402 will drive two protrusions 403 to rotate. Before the connecting disc 402 rotates, one of the protrusions 403 blocks one of the second connecting cylinders 202, while the other protrusion 403 blocks the other second connecting cylinder 202. When the connecting disc 402 rotates 90 degrees, one of the protrusions 403 no longer blocks one of the second connecting cylinders 202, while the other protrusion 403 blocks the other second connecting cylinder 202. Therefore, when it is necessary to rotate one of the second connecting cylinders 202 to replace its internal filter element 205, the other second connecting cylinder 202 cannot be rotated, thus avoiding incorrect rotation and effectively improving the stability of use.

[0033] This application discloses the implementation principle of a water purifier as follows: During use, a water delivery pipe is connected to an inlet pipe 206 and a drain pipe 212. Water enters the inlet pipe 206 and flows into one of the connecting sleeves 207. During flow, the water is guided through a channel 209 and flows into one of the first connecting cylinders 201. The water is then purified by a filter element 205 and finally flows from one of the connecting pipes 210 into the next connecting sleeve 207 for further purification. The purified water is then discharged from the drain pipe 212, thus achieving multiple purification processes and effectively improving the water purification effect. When replacing filter element 205, first ensure that the insert block 302 is not locked to the slot 304. Then, rotate valve block 208 90 degrees. This rotation changes the position of through groove 209, altering the water flow path. Water then flows into the other first connecting cylinder 201 and is filtered through another filter element 205. Simultaneously, the filter element 205 to be replaced can be removed and replaced without stopping the machine. This allows for continuous water purification, preventing delays in food production due to filter element 205 replacement and effectively ensuring production efficiency. The second connecting cylinder 201 can be opened during filter element replacement. The second connecting cylinder 202 is twisted off from the first connecting cylinder 201. Multiple protrusions 203 prevent hand slippage during rotation of the second connecting cylinder 202, thus improving stability. The filter element 205 is removed along with the second connecting cylinder 202, enabling quick disassembly and easy replacement. During filter element installation, the filter element 205 is taken into the second connecting cylinder 202, and one end of the filter element 205 engages with the positioning ring 204 on the second connecting cylinder 202, thus positioning the filter element 205. Then, the second connecting cylinder 202 is twisted onto the first connecting cylinder 201. When the second connecting cylinder 202 and the first connecting cylinder 201 come into contact, one end of the filter element 205 will... The filter element 205 is installed by contacting the second connecting cylinder 202 at one end and the first connecting cylinder 201 at the other. After installation, the other end of the filter element 205 engages with another positioning ring 204 on the first connecting cylinder 201, further positioning the filter element 205. It is worth noting that during the rotation of the valve block 208, the valve block 208 drives the connecting shaft 401 to rotate, which in turn drives the connecting disc 402 to rotate. The rotation of the connecting disc 402 causes two protrusions 403 to rotate. Before the connecting disc 402 rotates, one protrusion 403 blocks one of the second connecting cylinders 202, while the other protrusion 403 blocks the other second connecting cylinder 202.When the connecting disc 402 rotates 90 degrees, one of the protrusions 403 does not obstruct one of the second connecting cylinders 202, while the other protrusion 403 obstructs the other second connecting cylinder 202. Therefore, when one of the second connecting cylinders 202 needs to be rotated to replace its internal filter element 205, the other second connecting cylinder 202 cannot be rotated, thus preventing incorrect rotation and effectively improving operational stability.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
