Description

Technical Field

[0001] The utility model relates to the field of pure water machines, in particular to a pure water machine with a composite filter element. Background Art

[0002] A water purifier with a composite filter element usually combines multiple filtration technologies to provide efficient and multi-layer filtered pure water. When selecting a composite filter element, water quality issues should be taken into consideration, and suitable filter elements should be selected to perform good water filtration work.

[0003] The internal filter element of the existing pure water machine is usually fixed in length. When the currently used filter element cannot filter the water quality well, the only option is to purchase a longer filter element, which will undoubtedly increase the cost. After using the existing pure water machine for a long time, the internal filter element usually needs to be replaced as a whole. Even if the part is still in good condition, it cannot complete the subsequent filtering work well, which will further increase the cost. Since it is impossible to select the most suitable filter element configuration plan according to the water quality, its flexibility of use is extremely limited.

[0004] Therefore, those skilled in the art provide a water purifier with a composite filter element to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the prior art and to propose a water purifier with a composite filter element. The device can perform DIY assembly design on the filter element module according to the water quality, so that the filtration work can be carried out while minimizing resource allocation, which greatly saves the filtration cost. Moreover, through the modular design, the filter element module with poor filtration performance can be replaced in a targeted manner without replacing the entire unit, which further saves costs. At the same time, the device will perform targeted treatment on the first cup of water, which is convenient for detecting the internal cleanliness and improving safety.

[0006] To achieve the above-mentioned object, the utility model provides the following technical scheme: a water purifier of a composite filter element, comprising a water purifier body, a filter element module and a water blocking body, wherein the rear end of the water purifier body is penetrated by a water inlet, the rear end of the water purifier body is provided with multiple water receiving ports near the top of the water inlet, multiple water receiving ports are fixedly provided with a fixing groove at the center of one end near the water inlet, multiple sliding plates are slidably provided inside the filter element modules, multiple sliding plates are fixedly provided with a slide plate protrusion at the center of one end away from the water inlet, multiple sliding plates are provided with compression bodies on both sides of the slide plate protrusion on the same side of the slide plate protrusion, multiple support plates are fixedly provided inside the filter element modules near the compression body, multiple inner filter elements are sleeved around the slide plate protrusions, multiple inner filter elements are penetrated by T-shaped blocks, and multiple T-shaped blocks are provided with rubber protrusions on both sides of one end near the slide plate protrusion;

[0007] A top body is slidably provided inside each of the multiple water-blocking bodies, a water pipe is provided inside the water purifier body, a measuring body is fixedly provided on the water purifier body above the multiple measuring bodies on the same side of the multiple water inlets, a measuring bottle is slidably provided inside the measuring body, a water level measuring device is provided on the inner wall of the measuring bottle near the opening, a three-way valve is provided inside the water purifier body, a pure water chamber is provided inside the water purifier body away from the water inlet, two water outlets are provided inside the water purifier body near the bottom of the pure water chamber, water valves are provided inside the two water outlets near the pure water chamber, and a booster valve is provided inside the water purifier body near the water inlet;

[0008] Through the above technical solution, when the main body of the water purifier is working daily, the filter element modules can be matched according to the selection. All filter element modules are consistent, and multiple filter element modules can be connected in pairs. They all adopt threaded connection. After the connection, the internal T-shaped block or top body will push out the sliding plate. When each T-shaped block pushes out the sliding plate, the rubber protrusion will contact the slide plate protrusion and water cannot pass through it. The internal rubber protrusion of the filter element module connected to the last one will not contact the slide plate protrusion. At this time, the water will flow back to the water pipe from the other half chamber of the filter element module after flowing through the last filter element module, and enter the next water inlet through the water pipe.

[0009] Furthermore, the plurality of filter cartridge modules are all threadedly arranged inside the corresponding water inlet, and the plurality of filter cartridge modules are connected to each other by threaded connection;

[0010] Through the above technical solution, the threaded connection is quick and convenient, making it easier to assemble and design each filter element module.

[0011] Furthermore, the plurality of water-blocking bodies are all threadedly arranged inside the water inlet, and the plurality of water-blocking bodies only need to be arranged at the rear end of the last filter element module of a group of filter element modules;

[0012] Through the above technical solution, the internal sliding plate is kept stable, water leakage is prevented, and the sealing performance is improved.

[0013] Furthermore, the plurality of inner filter elements are assembled in different steps. There are three types of the plurality of inner filter elements, namely, PP cotton filter element, granular activated carbon filter element and compressed activated carbon filter element. The plurality of inner filter elements can be slightly compressed.

[0014] Through the above technical solution, since the water quality in each area is different, different filter elements can be used according to the water quality and assembled through the same filter element module, so that the filtration work can be more adapted to the water quality and avoid unnecessary costs.

[0015] Furthermore, the plurality of compression bodies are arranged on one side of the corresponding support plate close to the water inlet, and a No. 1 spring is arranged between adjacent support plates of the plurality of compression bodies;

[0016] Through the above technical solution, when the filter element module is removed, the extrusion on the internal sliding plate is released, and the sliding plate is affected by the No. 1 spring to re-seal the water outlet.

[0017] Furthermore, the dimensions of the ends of the T-shaped blocks away from the water inlet are consistent with the dimensions of the fixing groove and there is a certain friction between the ends and the fixing groove, and the material of the rubber protrusions is rubber;

[0018] With the above technical solution, when the sliding plate is squeezed, its slide plate protrusions will first contact the rubber protrusions. If it is still squeezed, its internal T-shaped blocks will slide in the fixed grooves.

[0019] Furthermore, the plurality of sliding plates are rectangular plates, and the interiors of the plurality of filter element modules are cylindrical spaces;

[0020] Through the above technical solution, when the sliding plate is squeezed, it will separate from the water outlet of the adjacent filter module, and water can flow out from the water outlet of the filter module. When the sliding plate is not squeezed, it will block the water outlet of the filter module and water cannot flow out.

[0021] Furthermore, the water level measuring device is electrically connected to the main body of the water purifier, the three-way valve is electrically connected to the main body of the water purifier, and the water valve is electrically connected to the main body of the water purifier;

[0022] Through the above technical solution, the water level meter feeds back the internal water level in real time, and sends a signal to the water purifier body when the water level reaches a predetermined threshold, so that the water purifier body controls the three-way valve to allow water to flow into the pure water chamber.

[0023] The utility model has the following beneficial effects:

[0024] 1. The utility model proposes a water purifier with a composite filter element. The device has a filter element module with the required inner filter element through modular design. The filter element modules can be assembled in combination. After assembly, the sliding plate can be controlled by the top body and the T-shaped block. Through the cooperation of the rubber protrusion and the slide plate protrusion, water will only flow from the last filter element module assembled and set at the same water inlet into the next half area of the assembled filter element module, which greatly improves the flexibility of assembly. It can be designed and assembled freely according to the water quality of the water source to be filtered, greatly saving costs and resource allocation while meeting the filtration work. At the same time, after long-term filtration, the filter element modules with poor filtration performance can be targetedly replaced according to the usage of each filter element module, further saving replacement costs and improving filtration efficiency.

[0025] 2. The utility model proposes a water purifier with a composite filter element. The device uses a designed three-way valve and a measuring bottle. When the water purifier body has not been used for a long time, the first cup of water will be directed into the measuring bottle. After the water level threshold is reached in the measuring bottle, the water can be directed into the pure water chamber. The internal filtration status and cleanliness level can be detected by the collected first cup of water. At the same time, the poor quality of the first cup of water can be avoided to affect the use and drinking, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

When assembled, the T-shaped block 23 will enter the fixing groove 10, and when the sliding plate 16 is not squeezed, it will only be in the weak friction area. When the sliding plate 16 is squeezed, the T-shaped block 23 will enter the strong friction area, so that the rubber protrusion 13 can better contact with the slide plate protrusion 12,

A compression body 15 is provided on both sides of the slide plate 12 on the same side of the slide plate 12. A support plate 14 is fixedly provided near the compression body 15 inside the multiple filter cartridge modules 3. An inner filter cartridge 11 is sleeved around the multiple slide plate 12. The inner filter cartridge 11 can be selected and matched according to the filtration process. A T-shaped block 23 is provided throughout the interior of the multiple inner filter cartridges 11, and rubber bumps 13 are provided on both sides of one end of the multiple T-shaped blocks 23 close to the slide plate 12.

A measuring bottle 18 is slidably provided inside the measuring body 4. A water level measuring device 19 is provided on the inner wall of the measuring bottle 18 near the opening.

[0037] The three-way valve 20 will first lead the water into the measuring bottle 18. When the water level in the measuring bottle 18 reaches the water level measuring device 19, a signal will be sent to the water purifier body 1 to control the three-way valve 20 to allow the water to flow into the pure water chamber 21. The three-way valve 20 is provided throughout the water purifier body 1. A pure water chamber 21 is provided in the water purifier body 1 away from the water inlet 5. Two water outlets 2 are provided in the water purifier body 1 near the bottom of the pure water chamber 21. Water valves 22 are provided in the two water outlets 2 near the pure water chamber 21. A booster valve 9 is provided in the water purifier body 1 near the water inlet 6.

[0038] When the water purifier body 1 is in daily operation, the filter element modules 3 can be matched according to selection. All filter element modules 3 are consistent, and multiple filter element modules 3 can be connected in pairs. They all adopt threaded connection. When connected, the internal T-shaped block 23 or the top body 17 will push out the sliding plate 16. When each T-shaped block 23 pushes out the sliding plate 16, the rubber protrusion 13 will contact the slide plate protrusion 12, and water cannot pass through it. The rubber protrusion 13 inside the last filter element module 3 will not contact the slide plate protrusion 12. At this time, the water will flow back to the water pipe 8 from the other half chamber of the filter element module 3 after flowing through the last filter element module 3, and enter the next water inlet 6 through the water pipe 8;

The threaded connections are quick and convenient, making it easier to assemble and design the filter elements 3. The water-blocking bodies 7 are all threadedly arranged inside the water inlet 6. The water-blocking bodies 7 only need to be arranged at the rear end of the last filter element 3 of a group of filter elements 3 to keep the internal sliding plate 16 stable while preventing water leakage and improving the sealing performance. The multiple inner filter elements 11 are assembled differently according to the steps. There are three types of the multiple inner filter elements 11, namely, PP cotton filter element, granular activated carbon filter element and compressed activated carbon filter element. The multiple inner filter elements 11 can be slightly compressed. Since the water quality in each area is different, different filter elements can be assembled through the same filter element module 3 according to the water quality, so that the filtration work can be more adapted to the water quality and avoid unnecessary costs.

[0040] A plurality of compression bodies 15 are arranged on one side of the corresponding support plate 14 close to the water inlet 5. A number of compression bodies 15 are provided between adjacent support plates 14 with a number 1 spring. When the filter element module 3 is removed, the extrusion of the internal sliding plate 16 is released, and the sliding plate 16 is affected by the number 1 spring to re-seal the water inlet. The size of the end of the plurality of T-shaped blocks 23 away from the water inlet 5 is consistent with the size of the fixed groove 10 and there is a certain friction between them and the fixed groove 10. The plurality of rubber protrusions 13 are made of rubber. When the sliding plate 16 is squeezed, its slide plate protrusion 12 will first contact with the rubber protrusion 13. If it is still squeezed, its internal T-shaped block 23 will slide in the fixed groove 10.

[0041] Multiple sliding plates 16 are rectangular plates, and multiple filter cartridge modules 3 have cylindrical spaces inside. When the sliding plate 16 is squeezed, it will separate from the water outlet of the adjacent filter cartridge module 3, and water can flow out from the water outlet of the filter cartridge module 3.

The water level meter 19 provides real-time feedback on the internal water level, and sends a signal to the water purifier body 1 after the water level reaches a predetermined threshold, so that the water purifier body 1 controls the three-way valve 20 to allow water to flow into the pure water chamber 21.

[0042] Working principle: The device can freely assemble the filter element module 3 and the inner filter element 11 according to the water quality of the water source to be filtered, so that it can meet the filtration work at the lowest cost. The filter element module 3 can be threadedly connected to the water inlet 6, and each filter element module 3 can also be threadedly connected at the head and tail. The tail end of the last filter element module 3 in the multiple filter element modules 3 assembled at the same water inlet 6 needs to be threadedly connected to a water blocking body 7. When the assembly is completed, water will enter the interior of the filter element module 3. Due to the T-shaped block 23 and the top body 17 provided inside, they will act on the sliding plate 16, so that water can be The water flows between the two chambers. The adjacent rubber protrusions 13 of the sliding plate 16 acted upon by the T-shaped block 23 will contact the slide plate protrusions 12. At this time, water cannot pass through. The rubber protrusions 13 of the sliding plate 16 acted upon by the top body 17 will not contact the slide plate protrusions 12. At this time, the water can flow into the next half chamber of the filter element module 3 and then flow back to the water pipe 8 for subsequent work. When the water flows into the three-way valve 20 for the first time, it will be guided by the three-way valve 20 to flow into the measuring bottle 18. After the water level reaches the predetermined threshold of the water level meter 19 in the measuring bottle 18, it will send a signal to the pure water machine body 1. At this time, the pure water machine body 1 will control the three-way valve 20 to guide the water to the pure water chamber 21 for subsequent use.
