Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, in particular to a water purifier and a direct drinking machine. Background Art

[0002] There are various types of water purifiers on the market. According to different application scenarios, they basically include three categories: household, commercial and portable. Among them, household types focus on silent technology and miniaturized design. In addition to the initial miniaturization of portable types, they also focus on breakthroughs in power supply methods and battery life. Among them, commercial models are mainly suitable for public places with large traffic flow, such as office buildings, schools, hotels, restaurants, and passenger stations. They need to meet the needs of many people concentrated and high-frequency drinking. In particular, these occasions often have a peak water consumption period, and a large amount of purified water needs to be quickly provided in a short period of time. In addition, although the current water supply facilities are basically complete and the quality of tap water sources is basically guaranteed, there is still the problem of uneven water quality. Therefore, compared with other water purifiers, users have higher requirements for the water output per unit time, water purification quality and speed of this type of commercial water purifier.

[0003] The core of a water purifier product is the filtration system, and it is often a composite filtration system with multi-stage filter elements, such as PP cotton, activated carbon, RO membrane filter elements and ultraviolet sterilization, so as to adapt to complex water quality. The RO membrane filter element is the core of the filtration system, with a filtration accuracy of up to micron level, which can remove heavy metals, viruses, bacteria and soluble salts, and can directly produce pure water. At present, commercial water purifiers still have some defects. For example, in order to consider the convenience of space and maintenance, the RO reverse osmosis filter element of the water purifier is generally only set up one, resulting in the water production capacity being limited by the RO filter element, which cannot meet the short-term, large water production, and high-frequency water extraction and drinking needs of certain scenarios. If multiple sets of RO filter element pipelines are directly installed, this will not only increase the complexity of the pipelines and electrical connections, but also increase the processing difficulty and maintenance costs.

[0048] In some existing water purifier solutions, to increase water output, if multiple RO membrane filters are connected in parallel directly to the raw water pipeline, this not only reduces the internal space of the purifier, but also requires changes to other component configurations. More importantly, it is difficult to maintain a balanced water resistance between the multiple RO membrane filters, which can damage individual membranes and reduce water purification efficiency. Therefore, to provide a solution, this application provides the following implementation method.

[0049] See also Figure 1 、 Figure 2 and Figure 3 In some embodiments, the present application provides a water purifier, comprising:

[0050] The first filter element group 200 includes a PP cotton filter element 202 and an activated carbon filter element 203 connected in sequence;

[0051] The second filter element group 300 includes a booster pump 303, a pressure stabilizer 3031, a water inlet 304, a water outlet 305, and a plurality of RO membrane filter elements 302. The water inlet 304 is arranged in a long strip shape, and a water diversion cavity 3043 is constructed inside the water inlet 304;

[0052] Among them, the water inlet end of the PP cotton filter element 202 is connected to the water source, the water outlet end of the activated carbon filter element 203 is connected to the water inlet end of the booster pump 303, the booster pump 303, the pressure stabilizer 3031 and the water inlet part 304 are connected in sequence; the water inlet ends of several RO membrane filter elements 302 are respectively connected to the water diversion cavity 3043 of the water inlet part 304, and the water production ends of several RO membrane filter elements 302 are connected and merged to produce pure water.

[0053] In this example, the water purifier uses a PP cotton filter element 202 as the first-stage coarse filter element, which physically intercepts large impurities, provides preliminary water purification, and protects subsequent filter elements. The activated carbon filter element 203 serves as the second-stage filter element, adsorbing residual chlorine, organic matter, and odors. The second filter element assembly 300, which includes an RO membrane filter element 302, deeply desalinates the water purified by the first filter element assembly 200, removing heavy metals, viruses, and soluble contaminants, ultimately producing pure drinking water.

[0054] Furthermore, the second filter element assembly 300 comprises several RO membrane filter elements 302 arranged in parallel, which not only multiplies water production but also eliminates water pressure loss. Furthermore, even if a single membrane fails, it does not affect the overall operation of the filtration system and can be replaced directly. Furthermore, due to the structural characteristics of the RO membrane, its impact resistance is relatively weak. For example, frequent starts and stops of the booster pump 303 can cause water hammer, which can directly damage and render the filter element inoperable, reducing its filtration efficiency and service life. Therefore, the present application incorporates a pressure stabilizer 3031 at the outlet of the booster pump 303 to stabilize inlet pressure fluctuations and prevent damage to the filter element. The pressure stabilizer 3031 can be a pressure regulating valve, a pressure regulating tank, or other device. Furthermore, a water inlet element 304 with a water distribution chamber 3043 is provided. The water distribution chamber 3043 is sized appropriately according to the water inlet requirements of the RO membrane. This ensures that the incoming water is evenly distributed to each RO membrane filter element 302, thereby maintaining a balanced pressure during operation. This improves the water purification efficiency of the filtration system and extends its service life.

[0055] The water inlet 304 is a structural component formed from an integral molding process, such as by injection molding or casting. This not only provides a stable and sturdy structure, stably supporting the filter element structure, but also allows for complete disassembly. For example, by separating the water inlet 304 from the pressure regulator 3031 and its mounting, the filter elements can be removed for easy disassembly. To facilitate processing, the water diversion chamber 3043 can be configured to extend through both ends of the water inlet 304, with plugs 3042 provided at both ends to seal the water inlet 304.

[0056] See also Figure 2 、 Figure 3 and Figure 6 In some embodiments, the water purifier of the present application further includes: a water outlet member 305, which is constructed in a long strip shape. A water production chamber 3051 and a sewage discharge chamber 3052 are respectively constructed inside the water outlet member 305. The water production ends of the plurality of RO membrane filter elements 302 are respectively connected to the water production chamber 3051 of the water outlet member 305, and one end of the water production chamber 3051 is provided with a water production port 3053 for outputting the pure water produced by the plurality of RO membrane filter elements 302. The sewage ends of the plurality of RO membrane filter elements 302 are respectively connected to the sewage discharge chamber 3052 of the water outlet member 305, and one end of the sewage discharge chamber 3052 is provided with a sewage discharge port 3054 for discharging wastewater discharged by the RO membrane filter element 302.

[0057] The water outlet 305 is designed for the parallel-connected RO membrane filter elements 302 and includes adjacent water production chambers 3051 and sewage discharge chambers 3052. These chambers 3051 and sewage discharge chambers 3052 are positioned to correspond to the water production and sewage discharge ends of the RO membrane filter elements 302, respectively. Water produced by the water production ends of each RO membrane filter element 302 is collected within the water production chamber 3051 and then discharged through a water production port 3053 at one end of the water production chamber 3051. Wastewater produced by each RO membrane filter element 302 is collected within the sewage discharge chamber 3052 and then discharged from the water purification system through a sewage discharge port 3054 at one end of the sewage discharge chamber 3052.

[0058] The water production chamber 3051 and the sewage discharge chamber 3052 are located on the same water outlet member 305, eliminating the need for complex piping and facilitating easy installation and maintenance. The water outlet member 305 is a one-piece structural component, such as one-piece injection molding or casting, which not only provides high structural strength but also excellent sealing performance.

[0059] See also Figure 4 and Figure 5In some embodiments, the projection of the water diversion chamber 3043 in the length direction of the water inlet member 304 is circular, and a first water inlet 3044 in the form of a circular hole is provided on one side of the water inlet member 304.

[0060] The inner diameter of the water diversion chamber 3043 is larger than the sum of the inner diameters of the water inlets of each RO membrane filter element 302, that is, the inner diameter of the water diversion chamber 3043 is larger than the sum of the inner diameters of each first water outlet 3045, thereby ensuring balanced water pressure across each RO membrane filter element 302. The outlet of the pressure regulator 3031 is connected to the first water inlet 3044 via a pipeline, and the water inlet of the RO membrane filter element 302 is connected to the first water outlet 3045 via a pipeline, facilitating connection and disassembly.

The pressure regulating valve 3046 and the pressure gauge 3047 are used to adjust the water pressure at the water inlet of the RO membrane filter element 302, thereby ensuring that the water inlet pressure of each RO membrane filter element 302 is consistent, thereby protecting the efficiency and life of the water purifier.

[0066] The water inlet pump 205 can be a variable frequency pump for pumping water. The outlet of the water inlet pump 205 is connected to the inlet of the PP cotton filter element 202. The inlet of the taste filter element 204 is connected to pure water.

During peak water consumption, the water outlet pump 206 is used to increase the water outlet pressure and speed of the taste filter 204, further supporting the demand for high-volume water purification in a short period of time.

[0068] See also Figure 8 、 Figure 9 and Figure 10In some embodiments, the present application provides a direct drinking machine, comprising the above-mentioned water purifier; a shell, wherein a first filter chamber 2, a second filter chamber 3, a water storage chamber 5 and a water intake chamber 4 are provided inside the shell; a water storage tank 500 and a water intake tank 400; a water intake level 6 is provided on one side of the shell, and the water intake level 6 is provided with a water intake platform 601 located below and a plurality of water intake ports 401 located above, the water storage chamber 5 is located below the water intake platform 601, and the water intake chamber 4 is located above the water intake port 401; the first filter chamber 2 is located on the side adjacent to the water intake chamber 4, and the second filter chamber 3 is located on the side adjacent to the water storage chamber 5; wherein, the first The filter element group 200 is arranged in the first filter chamber 2, the second filter element group 300 is arranged in the second filter chamber 3, the water storage tank 500 is arranged in the water storage chamber 5, and the water intake tank 400 is arranged in the water intake chamber 4; the water inlet end of the second filter element group 300 is connected to the water outlet end of the first filter element group 200, the water outlet end of the second filter element group 300 is connected to the water storage tank 500, the water outlet end of the water storage tank 500 is connected to the taste filter element 204, and the outlet end of the taste filter element 204 is respectively connected to the water intake pump and the water intake tank 400, the outlet end of the water intake pump is connected to the water intake tank 400, and the water intake 401 is connected to the water intake tank 400.

Based on the outlet water pressure and the liquid level in the water intake tank 400, the outlet pump 206 and the opening and closing of valves SV1 and SV2 can be regulated to accommodate different water intake and drinking frequency requirements. For example, when the outlet water pressure of the taste filter cartridge 204 and the water level in the water intake tank 400 are sufficient, the water intake pump does not operate, valve SV2 is closed, and SV1 is opened, allowing the water from the taste filter cartridge 204 to naturally enter the water intake tank 400. When the outlet water pressure of the taste filter cartridge 204 and the water level in the water intake tank 400 are insufficient, the water intake pump is activated, valve SV2 is opened, and SV1 is closed, allowing the water intake pump to pressurize and replenish the water.

[0073] A valve SV3 may be provided on the water intake 401 to facilitate the user to operate the valve SV3 to open and close to take water.
