Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and more specifically, it relates to a water treatment device. Background Technology

[0002] Gravity-based water purifiers are widely used in both home and outdoor settings because they require no external power supply and rely on natural gravity for water filtration. Current gravity filters generally use a single filter element structure, such as a ceramic or PP cotton filter. While these can remove some suspended particles, they have the following significant drawbacks:

[0003] 1. The filter cartridge itself does not have a sterilization function, and bacteria, viruses and other microorganisms may still remain in the filtered water, posing a risk of secondary pollution;

[0004] 2. The filter element is a single encapsulated unit, which needs to be replaced as a whole when its lifespan expires, resulting in high maintenance costs and making it inconvenient to clean or replace the filter media;

[0005] 3. The filter element and the housing are designed as one piece, which is large in size and concentrated in weight. During transportation or carrying, the filter element is easily damaged or the housing is cracked due to vibration or collision.

[0006] 4. The lack of real-time water volume display makes it difficult for users to determine the remaining purified water volume, affecting the user experience.

[0007] Therefore, the market urgently needs a new type of water treatment equipment that can both filter efficiently and sterilize instantly, while also being easy to transport and maintain. Utility Model Content

An external power source can charge the battery 32 through the charging port 37. Furthermore, the air inlets / outlets 38 are several circular holes formed on the side wall of the ozone base 30, arranged in a matrix. The air inlets / outlets 38 are used to balance the air pressure in the ozone generator 31's air path, ensuring stable ozone output. Furthermore, in order to strengthen the support of the ozone base 30 for the water storage tank 20 and the filter water tank 10, a plurality of support rods 54 are provided on the inner bottom wall of the ozone base 30, and the two ends of the support rods 54 are respectively connected to the ozone base 30 and the water storage tank 20.

[0044] Specifically, the ozone generator 31 is fixed to the bottom of the water storage tank 20 via the ozone base 30, and the aeration head 35 extends into the water storage tank 20 to evenly diffuse ozone into the water. The ozone switch 36 is a push-button type, the battery 32 is a rechargeable lithium battery, and the charging port 37 is a commonly used Type-C interface or DC power interface.

[0045] Specifically, battery 32 supplies power to ozone generator 31, and charging port 37 is electrically connected to battery 32; air inlet and outlet 38 are connected to the air passage of ozone generator 31 and are used for external air input and ozone gas output to aeration head 35.

[0046] Specifically, the ozone base has a support 50 at its bottom, which includes a support net 51 and at least three legs 52 located around the support net 51. A silicone pad 53 is placed between the ozone base 30 and the support 50. The outer ring of the support net 51 is circular, and the inside of the ring is a grid formed by multiple long strips connected in an intersecting pattern. The legs 52 have a certain height, and their upper ends are fixedly connected to the support net 51 to provide support, ensuring that the ozone base 30 is kept at a certain distance from the surface where the equipment is placed. The bottom of the legs 52 is provided with an anti-slip pad, such as a rubber pad. The silicone pad 53 is a cylindrical shape with openings at both the top and bottom, with the top opening being larger than the bottom opening. During installation, it is fitted onto the ozone base 30 from the bottom, providing a cushioning and protective effect.

[0047] Specifically, one end of the filter 40 extends into the water filter tank 10, and the other end extends into the water storage tank 20. The filter 40 is sealed to the bottom of the water filter tank 10. The filter 40 includes a primary filter 41 and a secondary filter 42. The bottom of the water filter tank 10 has a mounting hole matching the filter 40, and the filter 40 is a vertically arranged tubular structure. The primary filter 41 and the secondary filter 42 are coaxially arranged. The primary filter 41 has an external thread at its bottom, and the secondary filter 42 has an internal thread at its top. The primary filter 41 is threadedly connected to the top of the secondary filter 42. Furthermore, the externally threaded portion of the primary filter 41 extends through the bottom wall of the water filter tank 10 and communicates with the secondary filter 42. The joints between the primary filter 41 and the secondary filter 42 and the bottom of the water filter tank 10 are sealed with a sealing ring to prevent water leakage.

[0048] Specifically, the primary filter 41 is a coarse filtration structure, and the secondary filter 42 is a fine filtration structure. The raw water in the filter tank 10 flows into the secondary filter 42 for fine filtration after being coarsely filtered by the primary filter 41. Finally, the filtered water flows out to the storage tank 20 and mixes with the ozone generated by the ozone component for disinfection. The secondary filter 42 includes a detachably connected upper shell 421, a lower shell 422, and a detachable filter element 423 encapsulated in the shell.

[0049] The primary filter 41 is located inside the water filter tank 10. It employs a coarse filtration structure, such as a ceramic filter or ultrafiltration, with a filtration accuracy of 5-10μm. It is used to intercept large particulate impurities in the raw water, such as silt, rust, and suspended solids. After the raw water is injected through the first opening 11 at the top of the water filter tank 10, it undergoes coarse filtration through the primary filter 41, removing most of the visible impurities.

[0050] The secondary filter 42 is located above the water storage tank 20 and is connected to the lower end of the primary filter 41. It adopts a fine filtration structure, specifically a multi-layer filter element 423 composite structure. The filter element 423 material can be activated carbon, maifan stone balls, quartz sand, alkaline balls, adsorption resin, or other materials with impurity filtration and adsorption functions. In specific applications, the filter element 423 can be selected with more effective filtration materials according to the different pollutants in the water source. For example, a composite filter element 423 of activated carbon filter element 423 and ceramic membrane has a filtration accuracy of 0.1-1μm and is used to further adsorb organic matter, residual chlorine, and intercept fine particles. After the water passes through the primary filter, it flows into the secondary filter 42, where it undergoes fine filtration to obtain purer water, which finally flows into the water storage tank 20 to mix with ozone. Furthermore, the secondary filter 42 adopts a detachable design. Its outer shell consists of an upper shell 421 and a lower shell 422 connected by threads or snaps. The upper shell 421 and the lower shell 422 are respectively provided with an inlet and an outlet. The internally encapsulated filter element 423 can be pulled out and replaced for easy maintenance.

[0051] Specifically, a visible water level gauge 22 is vertically installed on the outside of the water storage tank 20 and is connected to it. The visible water level gauge 22 is partially or entirely made of transparent plexiglass, and scales are marked on the outside of the visible water level gauge 22. The bottom of the visible water level gauge 22 is level with the lowest water level in the water storage tank 20, which is used to visually display the remaining water in the water storage tank 20. By observing the water level in the water storage tank 20 through the visible water level gauge 22, water can be added to the filter water tank 10 for filtration in a timely manner.

[0052] Specifically, the water storage tank 20 has a second opening 23 at its top, and the filter water tank 10 is detachably mounted on top of the water storage tank 20; the ozone base 30 has a third opening 34 at its top, and the water storage tank 20 is detachably mounted on top of the ozone base 30, facilitating regular disassembly, cleaning, and transportation. An outwardly flanged receiving portion 55 is provided at the second opening 23 at the top of the water storage tank 20, and a corresponding protruding connecting portion 56 is provided below the filter water tank 10. The outer diameter of the filter water tank 10 is smaller than the inner diameter of the water storage tank 20. After the filter water tank 10 is inserted into the water storage tank 20 through the second opening 23 for a certain distance, its connecting portion 56 abuts against the receiving portion 55, serving a positioning and support function. Similarly, an inwardly flanged receiving portion 55 is provided at the third opening 34 at the top of the ozone base 30, and a corresponding recessed connecting portion 56 is provided at the bottom of the filter water tank 10. After the water storage tank 20 is inserted into the ozone base 30 through the third opening 34 for a certain distance, its connecting portion 56 abuts against the receiving portion 55, serving a positioning and support function.

[0053] Specifically, the outlet valve 21 is located at the bottom of the water storage tank 20 and is manually controlled. Its inlet end is connected to the inside of the water storage tank 20, and its outlet end is connected to a faucet. When water is needed, the outlet valve 21 is opened, and the ozone water in the water storage tank 20 flows out under gravity. After the valve is closed, the water storage tank 20 remains sealed to prevent ozone leakage.

[0054] The water treatment process of this equipment is as follows:

[0055] Raw water injection and coarse filtration: Open the lid 12 of the filter water tank 10 and inject raw water into it. The raw water is coarsely filtered by the primary filter 41 to remove large particulate impurities and then flows into the secondary filter 42.

[0056] Fine filtration and purified water storage: The water after coarse filtration enters the secondary filter 42, which adsorbs organic matter and residual chlorine and traps small particles to obtain finely filtered purified water; the finely filtered purified water flows into the water storage tank 20 and mixes with ozone generated by the ozone component at the bottom of the water storage tank 20 for disinfection.

[0057] Water usage: After disinfection, open the water outlet valve 21, and the ozone-sterilized water in the storage tank 20 will flow out through the water outlet pipe; after use, close the valve, and the ozone component can be restarted as needed to disinfect the water in the storage tank 20 a second time (if it has not been used for a long time).

[0058] This utility model discloses a water treatment device that achieves efficient purification and disinfection of raw water through a layered structural design, multi-stage filtration, and ozone disinfection. At the same time, the device's ease of use and maintenance are improved through its detachable and visual functional design. It can be used in scenarios such as home use, camping, and field operations to perform coarse filtration, fine filtration, and ozone sterilization treatment on rivers, lakes, rainwater, or municipal tap water to obtain clean water that can be directly consumed.
