Description

Technical Field

[0001] The utility model belongs to water purification equipment, in particular to a household water purifier, in particular to a water purifier controlled by a float valve. Background Art

[0002] A water purifier is a treatment device that filters and purifies water. As people's requirements for quality of life become higher and higher, small purifiers suitable for home use are becoming more and more popular. Traditional water purifiers usually need to be powered on, and use electrically driven power devices such as pumps to control water intake and water shut-off. Sometimes, due to problems with electricity or water pressure, water intake and water shut-off cannot be reliably controlled, and the working noise is loud. In order to overcome the above problems of traditional water purifiers, there are also some water purifiers without pumps and electricity in the prior art. For example, a float can be used to control the water level and the on-off of the waterway. However, the structure of the existing water purifiers that control the on-off by a float is complex, and sometimes it is sucked or stuck, making it difficult to disconnect the waterway.

[0003] CN213865640U discloses a float valve assembly and a water purifier, wherein the float valve assembly comprises a water purification cavity, a floating block, a lever and a valve body; the water purification cavity is provided with a water purification inlet and outlet; the floating block can float up and down in the water purification cavity; the lever is hinged in the water purification cavity, the first end of the lever is driven to move by the floating block, the second end of the lever can move with the first end of the lever, and the second end of the lever is provided with a magnet; the valve body comprises a valve body pipeline and an iron body at least partially located in the water purification cavity, and when the magnet approaches or leaves the iron body, the iron body moves to open or close the valve body pipeline. The float valve assembly of this scheme has a simple structure, can effectively control the on-off of the water path, and is suitable for water purifiers without electricity and pumps. The disadvantage is that the second end of the lever with a magnet is arranged in the water purification cavity, and there is always water in the cavity. The magnet end is soaked in water for a long time, which is prone to rust and the like, and will also affect the water quality in the cavity, thereby affecting the water quality of the entire water purifier. Summary of the invention

[0004] The purpose of the utility model is to overcome the above defects and provide a water purifier controlled by a float valve.

[0005] To this end, the technical solution adopted by the utility model is as follows: a water purifier controlled by a float valve, comprising a filter element, pure water produced by the filter element enters a pure water kettle, the pure water kettle is connected to a float valve, and the float valve controls the on-off of the water path entering the filter element, characterized in that: the float valve comprises a cavity, the water path of the pure water kettle is connected to the cavity, a valve seat is installed on one side of the cavity, the valve seat is installed on the side facing away from the cavity, the water inlet pipeline passes through the valve body, and the on-off of the water inlet pipeline is controlled by a movable ferromagnetic valve core in the valve body; a longitudinal U-shaped groove is opened on the side of the cavity where the valve seat is installed, and the lower edge of the U-shaped groove is higher than the highest liquid level of the pure water kettle; the valve seat is provided with a pivot or a pivot hole, a lever is hinged on the pivot or the pivot hole and can rotate relatively, the first end of the lever extends into the cavity, the second end of the lever is provided with a magnet, and can cooperate with the ferromagnetic valve core in the valve body; a float is provided in the cavity, and the first end of the lever is pushed when the float rises.

[0006] The water purifier includes a pre-filter element and an RO filter element. The float valve is arranged on the water path between the pre-filter element and the RO filter element to control the on-off of the water inlet pipeline entering the RO filter element.

[0007] The cavity is connected with the pure water kettle through a water pipe below the cavity.

[0008] The use process of the utility model is as follows: when the water level of the pure water kettle rises, the water level in the cavity also rises, the float rises to push the first end of the lever, so that the lever rotates, and its second end is separated from the ferromagnetic valve core, so that the water inlet pipeline is cut off, and the filter element stops making water; when the water level of the pure water kettle drops, the water level in the cavity also drops, and after the float drops, the lever rotates in the opposite direction under the action of gravity, and its second end is attracted to the ferromagnetic valve core, so that the water inlet pipeline is opened, and the filter element starts making water. In this cycle, the automatic operation of the water purifier can be realized.

[0009] Compared with the prior art, the valve core and the iron body of the lever of the utility model are both arranged outside the cavity, that is, they will not contact the water in the cavity; since the lower edge of the U-shaped groove is also higher than the highest liquid level, water will not leak from the cavity, ensuring safe and reliable use.

DETAILED DESCRIPTION

[0015] See also Figure 1 The water purifier of this embodiment includes a raw water end 1. After the raw water enters, it first passes through the pre-filter element 2, and then enters the RO filter element 3 under the control of the float valve 5. The pure water produced by the RO filter element 3 enters the pure water kettle 4, and the waste water generated is discharged from the waste water end 6. The pure water kettle 4 is connected to the float valve 5, as described below.

[0016] See also Figures 2 to 4 . The float valve includes a cavity 51, the bottom end of which is connected to the pure water kettle through a pure water pipe 52, so that the water level in the cavity is consistent with that in the pure water kettle; there is a float 53 in the cavity, floating above the water level in the cavity. A valve seat 54 is installed on one side of the cavity; a U-shaped groove 55 is provided on the cavity on the side where the valve seat 54 is installed. It can be inferred that when the entire cavity is filled with water, the water will flow out of the U-shaped groove 55, so in fact the lower edge of the U-shaped groove is higher than the highest water level of the cavity, so that water leakage will not occur. A valve body 56 is installed on the side of the valve seat facing away from the cavity, and a raw water pipe 57 passes through the valve seat 56. It should be noted that the water in the raw water pipe this time is not the same as the water at the raw water end 1, and has been purified by the pre-filter 2, but for the RO filter element 3, the water in 57 is still the raw water entering the RO filter element, so 57 is still called the raw water pipe. The valve body 56 is provided with a valve core 561, which moves in translation under the action of a magnet to control the on-off of the raw water pipe 57. The upper end of the valve seat 54 is provided with a pivot hole for installing a lever 58; the lever 58 includes a pivot 580, which is installed in the pivot hole of the valve seat so that the lever can rotate around the pivot; the lever includes a first end 581 and a second end 582, the first end 581 extends into the cavity and cooperates with the float 53, and when the float rises, it pushes the first end 581 to rotate the lever; the second end 582 is provided with a magnet 583, which can cooperate with the valve core 561 to make the valve core move in translation relative to the valve body, thereby controlling the on-off of the raw water pipe 57.
