Problems solved by technology

When the water purifier is shut down, the reverse osmosis membrane is always soaked in the mixed solution of raw water and waste water, which will cause a lot of salt and heavy metal ions to penetrate into the water collection pipe of the pure water, causing the water purifier to shut down for a period of time. It is difficult to guarantee the cleanliness of the first glass of water when the machine is turned on

Embodiment 1

[0034] like figure 1 and figure 2 As shown, the filter element provided in this embodiment includes a housing 1 and a membrane assembly 2 fixed in the housing 1. The membrane assembly 2 divides the interior of the housing 1 into an inner cavity and an outer cavity 14; the housing 1 is provided with The raw water inlet 12 communicated with the inner chamber, the waste water outlet 13 communicated with the inner chamber and the purified water outlet 11 communicated with the outer chamber 14; the first end of the membrane module 2 is communicated with the raw water inlet 12, and the second end is communicated with the The waste water outlet 13 is connected; after the raw water enters from the first end of the membrane module 2, part of the raw water can enter the outer cavity 14 after being filtered by the membrane module 2, and the other part is discharged from the waste water outlet 13 after passing through the membrane module 2.

Embodiment 2

[0066] The water purifier provided in this embodiment includes a control chip and the filter element provided in Embodiment 1, and a water inlet control valve is arranged on the water inlet channel of the filter element, and a drainage control valve is arranged on the waste water drainage channel of the filter element. Both the valve and the drainage control valve are connected with the control chip; the water purifier also includes a high pressure switch for detecting the pressure data of the purified water outlet 11, the high pressure switch is connected with the control chip, and the control chip receives the pressure data sent by the high pressure switch, and When the pressure data reaches the preset threshold value, the water inlet control valve is controlled to be closed. The drain control valve is normally open.

[0067] The filter element is a key component in the water purifier, and its cleanliness directly affects the cleanliness of the produced water, so it is very ...

Abstract

The invention provides a filter element and a water purifier, and relates to the technical field of filter elements. The filter element comprises a shell and a membrane component fixedly arranged in the shell, wherein the membrane component is used for dividing the inner part of the shell into an inner cavity and an outer cavity; the shell is provided with a raw water inlet communicated with the inner cavity, a waste water outlet communicated with the inner cavity, and a purified water outlet communicated with the outer cavity; the first end of the membrane component is communicated with the raw water inlet, and the second end is communicated with the waste water outlet. After the raw water enters from the first end of the membrane component, one part of membrane component is filtered by the membrane component to enter the outer cavity, and the other part passes through the membrane component to be discharged out of the waste water outlet. According to the filter element and the waterpurifier, the technical problems in the prior art that a reverse osmosis membrane is dipped in mixed solution of raw water and waste water during water purifier halting, a great quantity of salt and heavy metal ions can be permeated into a collector pipe for discharging pure water, and therefore, the clean degree of the first cup of water of the water purifier is difficult to be guaranteed when the water purifier is started after the water purifier halts for a period of time are mitigatedcan be solved.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a filter element and a water purifier. Background technique [0002] Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform deep filtration and purification of water quality according to the requirements for water use. [0003] In the prior art, the reverse osmosis membrane filter element used in the water purifier collects and discharges pure water from a central water collection pipe. When the water purifier is shut down, the reverse osmosis membrane is always soaked in the mixed solution of raw water and waste water, which will cause a lot of salt and heavy metal ions to penetrate into the water collection pipe of the pure water, causing the water purifier to shut down for a period of time. When starting up, the cleanliness of the first cup of water is difficult to guarantee. Contents of the invention [0004] T...
