Description

Technical Field

[0001] The invention belongs to the technical field of zero-stale water RO reverse osmosis water purifiers, and in particular relates to an anti-fouling device for a water purifier. Background Art

[0002] A water purifier is a device used to purify water. Its main purpose is to remove impurities, pollutants, harmful substances in water and improve the taste of water, so that the water meets certain quality standards and is suitable for people to drink or other specific purposes. Some water purifiers contain activated carbon filters. Activated carbon has a rich pore structure and a strong adsorption capacity. It can adsorb residual chlorine, odorous substances, organic pollutants (such as some pesticide residues) in water. For example, if there is chlorine smell produced by bleaching powder in water, activated carbon can adsorb it and improve the taste of water. In the reverse osmosis water purifier, there is a semipermeable membrane. Under pressure, only water molecules can pass through this membrane, while tiny particles such as salt and heavy metal ions in the water are retained. For example, for heavy metals such as lead and mercury in water, reverse osmosis membranes can effectively block them to ensure the safety of drinking water.

[0003] When a water purifier is purifying water containing impurities, dirt easily adheres to and accumulates in the filter box, which is a technical problem that affects the purification effect and service life of the water purifier. Summary of the invention

[0004] In view of this, the present invention provides a water purifier anti-fouling device, which aims to solve the technical problem that dirt is easily attached and accumulated in the filter box during the process of purifying water containing impurities by the water purifier, thereby affecting the purification effect and service life of the water purifier.

[0005] The present invention is achieved in that: The present invention provides an anti-fouling device for a water purifier, which comprises a filter box, a water inlet hole, a spoiler, a filter screen, a safety valve and a box cover; the filter box is a square hollow structure; the box cover is arranged above the filter box; the water inlet holes are opened below the left and right side walls of the filter box; the spoiler is fixedly arranged on the inner wall of the box cover to disrupt the water flow in the filter box and prevent dirt from adhering; the water inlet hole is used to pass the water to be purified into the filter box.

[0006] On the basis of the above technical solution, the anti-fouling device for a water purifier of the present invention can also be improved as follows: Wherein, the filter screen is arranged inside the water inlet hole; an opening is arranged on the filter box; and the safety valve is arranged in the opening.

[0007] Furthermore, there are multiple spoilers, and the heights of the spoilers are different.

[0008] Furthermore, the mesh diameter of the filter is 0.5-0.8 mm; and the water to be purified is water containing impurities.

[0009] Furthermore, the spoiler is triangular.

[0010] Furthermore, the spoiler is trapezoidal.

[0011] Furthermore, the spoiler is wavy.

[0012] Furthermore, the filter is made of polyetheramide.

[0013] Compared with the prior art, the anti-fouling device for a water purifier provided by the present invention has the following beneficial effects: Improve purification effect: By setting spoilers of different shapes (triangle, trapezoid, wave) and heights on the inner wall of the box cover, the water flow can be effectively disrupted, forming a complex flow path in the filter box, reducing the chance of dirt adhering to the box wall, allowing impurities to be more fully intercepted by the filter, thereby improving the purification effect and ensuring that the output water quality is purer.

[0014] Extend the service life of the equipment: The filter screen is set at the water inlet to initially filter out larger particles of impurities, prevent them from entering the filter box, and reduce damage to internal components. At the same time, the safety valve can release the pressure in time when the internal pressure of the equipment is too high, avoiding damage to the equipment due to excessive pressure and extending the overall service life of the water purifier.

[0015] Reduce maintenance costs: The synergistic effect of the spoiler and the filter reduces the accumulation of dirt in the filter box and reduces the frequency of equipment maintenance. In addition, the filter made of polyetheramide has good durability and is not easy to damage, which further reduces maintenance costs.

[0016] The invention can solve the technical problem that during the process of purifying water containing impurities, dirt is easily attached and accumulated in the filter box, thus affecting the purification effect and service life of the water purifier. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4 As shown, it is a first embodiment of a water purifier anti-fouling device provided by the present invention. In this embodiment, it is provided with a filter box 1, a water inlet hole 2, a spoiler 3, a filter screen 4, a safety valve 5 and a box cover 6; the filter box 1 is a square hollow structure; a box cover 6 is arranged above the filter box 1; water inlet holes 2 are opened below the left and right side walls of the filter box 1; a spoiler 3 is fixedly arranged on the inner wall of the box cover 6 for disrupting the water flow in the filter box 1 and preventing dirt from adhering; the water inlet hole 2 is used to pass the water to be purified into the filter box 1.

[0021] When in use, open the water inlet valve, and the water to be purified containing impurities enters the filter box 1 through the water inlet hole 2. During the water inlet process, the filter 4 in the water inlet hole will preliminarily filter the larger particles of impurities in the water. After the water enters the filter box, it is affected by the spoiler 3, and the direction and speed of the water flow are constantly changed, forming a complex water flow state, making it difficult for impurities in the water to adhere to the box wall and easier to be intercepted by the filter. The purified water flows out from the water outlet of the filter box for users to use.

[0022] Among them, in the above technical solution, a filter screen 4 is arranged inside the water inlet hole 2; an opening is arranged on the filter box 1; and a safety valve 5 is arranged in the opening.

[0023] Furthermore, in the above technical solution, there are multiple spoilers 3; and the heights of the spoilers 3 are different.

[0024] Furthermore, in the above technical solution, the diameter of the holes of the filter screen 4 is 0.5-0.8 mm; the water to be purified is water containing impurities.

[0025] Furthermore, in the above technical solution, the spoiler 3 is triangular.

[0026] like Figure 52 is a second embodiment of a water purifier anti-fouling device provided by the present invention. In this embodiment, the spoiler 3 is trapezoidal.

[0027] like Figure 6 2 is a third embodiment of a water purifier anti-fouling device provided by the present invention. In this embodiment, the spoiler 3 is wavy.

[0028] Furthermore, in the above technical solution, the filter screen 4 is made of polyetheramide.

[0029] Specifically, the principle of the present invention is: open the water inlet valve, and the water to be purified containing impurities enters the filter box 1 through the water inlet hole 2. During the water inlet process, the filter screen 4 in the water inlet hole will preliminarily filter the larger particles of impurities in the water. After the water enters the filter box, it is affected by the spoiler 3, and the direction and speed of the water flow are constantly changed, forming a complex water flow state, so that the impurities in the water are not easy to adhere to the box wall, and are more easily intercepted by the filter screen. The purified water flows out from the water outlet of the filter box for users to use.
