Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a countertop water purifier. Background Technology

[0002] Currently, water purifiers on the market can be divided into various types according to different usage scenarios, such as built-in, under-sink, and countertop. Among them, countertop water purifiers are widely popular due to their easy installation and multiple functions.

[0003] Countertop water purifiers typically use a water tank for water supply. For countertop water purifiers using reverse osmosis or nanofiltration filters, the water tank stores not only the raw water used for purification but also the concentrated water generated during purification. When installing a new machine or replacing a new filter, users are generally required to rinse continuously for 30-60 minutes because the new filter (especially reverse osmosis or nanofiltration filters) contains a certain amount of protective fluid. During this process, the water in the tank needs to be repeatedly poured out and changed. The protective fluid flushed out in the concentrated water will be repeatedly carried to the front end of the reverse osmosis membrane for further filtration due to the backflow of the concentrated water, and then return to the original water tank with the wastewater. This prolongs the overall rinsing time and increases the number of water tank changes, making the rinsing process of countertop water purifiers cumbersome, time-consuming, and requiring a large amount of water to be changed, causing inconvenience to users. Utility Model Content

[0004] The purpose of this utility model is to propose a countertop water purifier that can effectively solve the problems of cumbersome rinsing process, long rinsing time, and large water exchange volume in countertop water purifiers.

[0005] To achieve the above objectives, this utility model proposes: A countertop water purifier includes a water tank with an inlet and an outlet; it also includes a filter assembly, which is detachably installed inside the water tank and connected to the inlet. The filter assembly includes a housing and a filter element, which is disposed in the housing and is replaceable. The filter element includes a hydrophilic and oil-absorbing filter element.

[0006] Based on the above technical means, the hydrophilic oil-absorbing filter element can intercept and adsorb the protective liquid in the concentrated water returned from rinsing the new filter element, thereby shortening the overall rinsing time and reducing the number of times the water in the water tank needs to be changed.

[0007] Furthermore, the filter element also includes one of a FOF scale inhibitor filter element and a softening resin filter element.

[0008] Based on the above technical means, FOF scale inhibitor filter cartridges or softening resin filter cartridges can reduce the risk of scale buildup and blockage at the concentrate outlet due to excessive scale hardness, while optimizing the raw water quality and reducing the filtration burden on new filter cartridges.

[0009] Furthermore, the water tank is equipped with a filter element holder, which is connected to the water inlet, and the housing is attached to the filter element holder by snap-fit ​​or threaded connection.

[0010] Furthermore, the filter assembly also includes a protective component disposed on the housing.

[0011] Furthermore, the protective component is made of stainless steel wire mesh or non-woven fabric.

[0012] Furthermore, the housing is a perforated plastic bracket or a stainless steel wire mesh bracket.

[0013] Furthermore, the water tank is equipped with a baffle that divides the inner cavity of the water tank into two parts.

[0014] Furthermore, the water tank is equipped with a float.

[0015] Furthermore, the water tank is equipped with a handle.

[0016] The beneficial effects of this utility model are: When users install and flush a new machine or replace a new filter cartridge, a hydrophilic oil-absorbing filter cartridge is installed inside the filter cartridge assembly. This cartridge intercepts and adsorbs the protective liquid in the flushing concentrate of the new filter cartridge (reverse osmosis or nanofiltration cartridges contain protective liquid, which generates a large amount of foamy wastewater during flushing). This effectively shortens the overall flushing time and reduces the number of times the water in the tank needs to be changed. It solves the problems of cumbersome flushing process, long flushing time, and large water volume in tabletop machines, making it more convenient for users.

[0017] After rinsing, remove the hydrophilic oil-absorbing filter cartridge and replace it with an FOF scale-inhibiting filter cartridge or a softening resin filter cartridge. This can optimize the composite antibacterial material or other filter media. When the concentrated water flows back to the water tank, it is blocked or softened by the filter cartridge before flowing back to the raw water tank. This reduces the risk of scale buildup and blockage at the concentrated water outlet due to excessively hard scale, while also optimizing the raw water quality, reducing the filtration burden on the reverse osmosis or nanofiltration filter cartridges, extending the lifespan of the countertop water purifier, and improving the user experience.

[0024] like Figure 1-4 As shown, one or more preferred embodiments of the countertop water purifier of this application will be disclosed and described in the following description.

[0025] A countertop water purifier includes a water tank 1 with an inlet 101 and an outlet 102. Both the inlet 101 and the outlet 102 are located at the bottom of the water tank 1 and are connected to it. Concentrated water enters the water tank 1 through the inlet 101. The purifier also includes a filter assembly 2, which is detachably installed inside the water tank 1 and connected to the inlet 101. The filter assembly 2 includes a housing 201 and a filter element 202. The housing 201 is a hollow cylindrical structure with openings at both ends. The filter element 202 is located inside the housing 201 and is replaceable. The filter assembly 2 is used to intercept and adsorb the protective liquid in the concentrated water returning from rinsing the new filter element or to reduce the risk of scale buildup and blockage at the concentrated water outlet due to excessively high water hardness.

[0026] In this embodiment, the filter element 202 includes a hydrophilic oil-absorbing filter element, which can intercept and adsorb the protective liquid in the concentrated water returned from rinsing the new filter element, thereby shortening the overall rinsing time and reducing the number of times the water in the water tank needs to be replaced.

[0027] In this embodiment, filter element 202 also includes one of FOF scale inhibitor filter element and softening resin filter element. FOF scale inhibitor filter element or softening resin filter element can reduce the risk of scale blockage in the concentrate outlet due to excessive scale hardness, while optimizing the raw water quality and reducing the filtration burden of new filter elements.

[0028] In this embodiment, a filter element seat 103 is provided inside the water tank 1. The filter element seat 103 is located at the bottom of the water tank 1, above the water inlet 101 and connected to the water inlet 101. The housing 201 is attached to the filter element seat 103 by snap-fit ​​or threaded connection.

[0029] When the housing 201 is snapped onto the filter element holder 103, snap-fit ​​blocks and slots are provided on the housing 201 and the filter element holder 103. For example, if a snap-fit ​​block is provided at the lower end interface of the housing 201, then a corresponding slot is provided on the filter element holder 103.

[0030] When the housing 201 is threaded onto the filter element holder 103, external and internal threads are provided on the housing 201 and the filter element holder 103. For example, if an external thread is provided at the lower end interface of the housing 201, then a corresponding internal thread is provided on the filter element holder 103.

[0031] In this embodiment, the filter element holder 103 and the water tank 1 are an integral structure, cast using an integral molding method; or, the filter element holder 103 is fixedly installed in the water tank 1 by screws.

[0032] In this embodiment, the filter element assembly 2 also includes a protective component 203, which is located at the lower end of the housing 201. The protective component 203 is a stainless steel wire mesh or non-woven fabric, preferably a high-precision stainless steel wire mesh, which can reduce the resistance of concentrated water backflow and prevent the filter material from leaking out and clogging the concentrated water inlet 101, causing the whole machine to malfunction.

[0033] In this embodiment, the protective component 203 can be fixed to the lower opening of the housing 201 using screws or industrial adhesive.

[0034] In this embodiment, the housing 201 is a hollow plastic bracket or a stainless steel wire mesh bracket, which reduces the resistance to concentrated water backflow and increases the contact area between the filter element 202 and the water in the water tank, maximizing the function of the filter element 202.

[0035] In this embodiment, a baffle 104 is provided inside the water tank 1. The baffle 104 divides the inner cavity of the water tank 1 into two parts, reducing the amount of high-concentration concentrated water flowing back and isolating most of the concentrated water on the concentrated water side on the left side of the water tank 1, thereby optimizing and extending the service life of the filter element 202 of the countertop water purifier.

[0036] In this embodiment, a float 105 is provided in the water tank 1. The float 105 can rise and fall with the liquid level in the water tank 1 and can monitor the liquid level in the water tank 1.

[0037] In this embodiment, the water tank 1 is provided with a handle 106, which is rotatably connected to the top of the water tank 1, making it convenient for users to grip, lift or move the water tank 1.

[0038] It should be noted that water tank 1 is also equipped with an openable cover.

[0039] It should be noted that the water tank 1 is detachably installed on the main body of the water purifier. The new filter element is located between the water tank 1 and the main body of the water purifier. The new filter element can be a reverse osmosis filter element or a nanofiltration filter element. Since this application is an improvement on the water tank 1, the main body of the water purifier and the new filter element are not shown. This water tank 1 can be used with any water purifier main body that is compatible with this water tank 1.

[0040] This utility model is a countertop water purifier, and its operation is described in conjunction with the accompanying drawings: When installing and flushing a new machine or replacing a new filter element, the user first installs the hydrophilic oil-absorbing filter element inside the housing 201, then installs the filter element assembly 2 with the hydrophilic oil-absorbing filter element on the filter element seat 103 for flushing. The hydrophilic oil-absorbing filter element intercepts and adsorbs the protective liquid in the new filter element (reverse osmosis or nanofiltration filter elements contain protective liquid, which generates a large amount of foamy wastewater during flushing) and the protective liquid in the flushing return concentrate, effectively shortening the overall machine flushing time and reducing the number of times the water in the water tank needs to be changed, thus solving the problems of long flushing time and large water replacement volume in desktop machines.

[0041] After rinsing is complete, remove filter element assembly 2 and replace the hydrophilic oil-absorbing filter element with an FOF scale inhibitor filter element or a softening resin filter element. Reinstall the filter element assembly 202 on the filter element holder 103. When the concentrated water flows back to the water tank 1, it is scale-inhibited or softened by the filter element 202 before flowing back to the water tank 1. This reduces the risk of scale buildup and blockage at the concentrated water outlet due to excessively hard scale, while also optimizing the raw water quality, reducing the filtration burden on the new filter element (reverse osmosis filter element or nanofiltration filter element), extending the service life of the countertop water purifier, and improving the user experience.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
