Description

Water purifier and modular split water storage device

The invention relates to the field of electrical appliances, in particular to household drinking water purifier electrical equipment, specifically a drinking water purifier and a modular split water storage device thereof.

As people's quality of life improves, their awareness of drinking water safety has gradually increased. Household water purifiers have been rapidly promoted because the water they purify is of good quality and suitable for direct drinking. Initially, household portable water purifiers generally have a raw water tank for raw water and a purified water tank for filtered water. The raw water tank is generally detachably mounted on the body for easy access, while the purified water tank is only used to store filtered water and is often fixed inside the body without disassembly, resulting in the problem that the water tank of the water purifier is difficult to clean. If the water purifier is used for a long time, bacteria are easily bred in the water tank, which is unsafe for users to use.

In order to improve the above problems, the existing water purifiers are designed to have both the raw water tank and the purified water tank in a detachable manner. For example, the Chinese patent publication number is CN 115043511 A, the publication date is September 13, 2022, and the name is: Patent application for invention of water purifier, which includes a body, and a drinking water outlet is formed on one side of the body; a filter element assembly is arranged on the body, and the filter element assembly has a raw water inlet, a pure water outlet and a waste water outlet; the raw water tank is detachably arranged on the body, and the raw water tank has a raw water tank inlet and a raw water tank outlet, and the raw water tank outlet is connected to the raw water inlet The pure water tank is detachably connected to the machine body, the pure water tank and the drinking water outlet are located on the same side of the machine body, the pure water tank has a pure water tank inlet and a pure water tank outlet, the pure water tank inlet is connected to the pure water outlet, the pure water tank outlet is connected to the drinking water outlet, the pure water tank includes a pure water tank body and a pure water tank cover, the top of the pure water tank body is open, and the pure water tank cover is detachably connected to the top of the pure water tank body. The water purifier of this scheme detachably installs the raw water tank and the pure water tank on the machine body, so that the pure water tank is easy to clean and can also be used as a water storage container alone.

However, this solution still has disadvantages. The raw water tank and pure water tank are located at the front and rear sides of the water purifier respectively, which are far apart and inconvenient to operate. To a certain extent, it leads to the complexity of the internal water connection and divides the body into multiple areas, which is not conducive to the full utilization of the body space. If it is installed directly on the body, the body must reserve an adaptive space. It cannot be adapted for use with water purifiers of different specifications and models, and its versatility is relatively poor.

The purpose of the present invention is to provide a modular split water storage device for a water purifier, which solves the problem that the detachable raw water tank and the water purification tank body of the existing water purifier are divided into multiple areas, which is not conducive to the full utilization of the body space and the problem of relatively weak versatility.

In order to achieve the above-mentioned purpose, the present invention provides a modular split water storage device for a water purifier, comprising: a raw water tank, which has a raw water area for storing raw water, and a raw water outlet connected to the raw water area at the bottom; a clean water tank, which is used to store clean water after being purified by the water purifier, and has a clean water cavity for storing clean water, and a clean water inlet connected to the clean water cavity at the bottom; a water storage tank seat, which is used to carry the raw water tank and the clean water tank, and the raw water tank and the clean water tank are both supported and placed on the water storage tank seat in a removable manner; the water storage tank seat comprises a plastic material injection-molded integrally formed The base and the side stand are arranged in a horizontal position, and the side stand is arranged vertically on the front side of the base; the raw water tank and the clean water tank are arranged side by side on the base of the water storage tank seat in the left-right direction, with their front sides leaning against the side stand of the water storage tank seat, and the side surfaces of the two adjacent boxes are close to each other; the base of the water storage tank seat is provided with a raw water outlet matched with the raw water outlet of the raw water tank, and a clean water outlet matched with the clean water inlet hole of the clean water tank; the bottom of the base of the water storage tank seat is provided with a connector for detachably mounting the water storage tank seat on the frame of the water purifier.
