Description

Shell for water purifier

Technical Field

The present utility model relates to a water purifier, and more particularly, to a housing for a water purifier.

Background

The water purifier is also called a water purifier, and can purify raw water (such as tap water) according to the requirements of users so as to meet the needs of people. In many countries, especially in developing countries, water pollution problems become more and more serious with the continuous development of industry and agriculture, and the water source of domestic water for people is also affected by light or heavy weight. In addition, the quality of tap water is affected by the external environment and the water supply pipeline. For example, excessive sand content in the tap water source, ageing of the pipe network, poor quality of the tap water pipe, lack of cleaning of the water supply pipe network for a long time and the like can affect the quality of tap water. Therefore, tap water in many countries is of poor quality and unsuitable for direct drinking under the influence of many factors. The water purifier can effectively remove impurities such as sediment, colloid, rust, bacteria, even heavy metal ions and the like in raw water through the filtering effect of the purification device, so that the quality of domestic water is improved and improved, and the water purifier is increasingly favored by consumers. The existing household water purifier for purifying tap water mainly comprises a kitchen ultrafiltration water purifier, an RO membrane water purifier, a water softener and the like.

The water purifier (or water purifier) is used for treating raw water, water purification materials such as ultrafiltration membrane wires, activated carbon and the like are placed in the shell of the water purifier, and the raw water is purified after flowing through the water purification materials to obtain purified water. Raw water, particularly tap water, has a large water pressure, after raw water to be treated flows into the housing of the water purifier, the water pressure acts on the housing of the water purifier, and the housing of the water purifier needs to bear pressure for a long time. In addition, the water pressure of tap water often fluctuates, and a water hammer generated by the fluctuation of the water pressure also acts on the shell of the water purifier. In other words, the outer casing of the water purifier should have good flexibility to prevent it from being broken after being pressed for a long time or being subjected to a water hammer, thereby ensuring the safety of the water purifier. Therefore, many cases for water purifiers exist which have better flexibility. In addition, many cases for water purifiers are currently made of opaque materials having superior flexibility in view of manufacturing costs.

The housing for the water purifier, which is made of an opaque material, is flexible, but it is inconvenient for a user to view the use state of the filter cartridge of the water purifier. For example, many users are concerned about whether the water purification material has accumulated dirt and the color of the purification material has yellow and black due to long-term use, so that the filter element can be replaced in time. In order to meet the demands of users for observing the use state of the water purifier and replacing the filter element in time, many manufacturers use transparent materials to manufacture the shell for the water purifier, but most of transparent materials, such AS AS, PC, transparent ABS, PET and the like, have over-high rigidity and insufficient flexibility, and are easy to break when subjected to long-time action of external stress or water hammer caused by water pressure change. In order to ensure the safety of the water purifier, manufacturers have to increase the thickness of the water purifier housing or make it of an expensive transparent material which is particularly resistant to stress for a long period of time, resulting in a significant increase in the manufacturing cost thereof.

Therefore, there is a need in the market for a housing for a water purifier that can withstand water pressure, stress and water hammer for a long period of time to ensure safe use of the water purifier, that is convenient for a user to observe the use of the water purification material within the housing of the water purifier, and that is inexpensive.
