Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bathroom, in particular to a filter element assembly and a bathroom device. BACKGROUND

[0002] Now the popular intelligent toilet has the functions of washing buttocks, drying and deodorizing. At present, the water source directly from the water supply system usually contains impurities, which will reduce the service life of the booster device or even damage it if not filtered.

[0003] In the related art, a filter device is usually added to the intelligent toilet to filter the water. The filter device is generally composed of a filter element and a mounting assembly. The filter element is fixed by the mounting assembly, so that the water can be filtered under the action of the filter element. Due to the limited water filtering capacity of the filter element, the filter element needs to be replaced after long-term continuous work. A waterway switching valve core is generally provided to switch the waterway, so that the water can be conducted through another waterway in the absence of the filter element, thereby ensuring the water supply state during replacement or removal of the filter element.

[0004] However, the sealing ring for realizing the relative sealing of the two waterways on the valve core in the related art adopts an O-shaped sealing ring for radial sealing. Since the friction force is large when the valve core moves axially, the force requirement of the return spring is large in the case of limited stroke space. In addition, when the switching valve core moves at different pipe outlet places, the sharp burrs at the places will scratch the O-shaped ring, which will damage the O-shaped ring and cause the risk of sealing failure in the long term. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a filter element assembly and a bathroom device to solve the problem of easy sealing failure of the sealing ring.

[0006] In a first aspect, the present application provides a filter element assembly, comprising a cylinder assembly and a valve core.

DETAILED DESCRIPTION

[0038] To make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme in the embodiments of the application will be described clearly and completely below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are some of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0039] The embodiments of the application will be described below in conjunction with Figures 1 to 9 .

[0040] According to the embodiment of the present application, in one aspect, a filter cartridge assembly is provided, comprising a cartridge assembly 1 and a valve core 8, the side wall of the cartridge assembly 1 is provided with a water inlet channel 2 and a water outlet channel 3, the cartridge assembly 1 is provided with a connecting channel 4 and a cavity 5 inside, the first end of the connecting channel 4 is provided with a first annular boss 6, the annular space of the first annular boss 6 is adapted to communicate the connecting channel 4 and the cavity 5, the second end of the connecting channel 4 is provided with a second annular boss 7, the annular space of the second annular boss 7 is adapted to communicate the water outlet channel 3 and the connecting channel 4, and the connecting channel 4 communicates with the water inlet channel 2. The valve core 8 is arranged in the connecting channel 4 and can slide along the axial direction of the connecting channel 4 between a first position and a second position. In the state of the first position, the valve core 8 abuts against the second annular boss 7 and is adapted to block the annular space of the second annular boss 7. In the state of the second position, the valve core 8 abuts against the first annular boss 6 and is adapted to block the annular space of the first annular boss 6.

[0041] It can be understood that the water inlet channel 2 is used to introduce water to be filtered into the cartridge assembly 1, the water outlet channel 3 is used to discharge the water entering the cartridge assembly 1, the filter cartridge body 14 for filtering the introduced water to be filtered is arranged in the cavity 5, and the position movement of the valve core 8 is realized by the joint action of the filter cartridge body 14 and the spring. Specifically, when the filter cartridge body 14 is arranged in the cavity 5, the water inlet of the filter cartridge body 14 is positioned to penetrate the annular space of the first annular boss 6, which not only realizes the communication between the water inlet and the connecting channel 4, but also realizes the pushing effect on the valve core 8, so that the valve core 8 can be separated from the annular space of the first annular boss 6 and block the annular space of the second annular boss 7, thereby ensuring that the water entering the water inlet channel 2 can enter the water inlet through the connecting channel 4, and the water flowing out of the water outlet of the filter cartridge body 14 can compress the one-way valve 11, so that the one-way valve 11 is separated from the through hole 12, thereby realizing that the water in the water outlet can pass through the through hole 12 and enter the water outlet channel 3 and be discharged. When it is necessary to replace the filter cartridge body 14, i.e. when the cavity 5 is not arranged with the filter cartridge body 14, the valve core 8 can be lifted upward under the action of the first spring 10 to block the annular space of the first annular boss 6, at this time, the annular space of the second annular boss 7 is in an open state, and the water introduced from the water inlet channel 2 can directly enter the water outlet channel 3 through the annular space of the second annular boss 7 and be discharged.

[0042] It should be noted that the first annular boss 6 and the second annular boss 7 are arranged such that the area of the connection channel 4 communicating with the cavity 5 and the water outlet channel 3 is smaller than the inner diameter of the connection channel 4 (i.e. the diameter of the annular space of the first annular boss 6 and the second annular boss 7 is smaller than the inner diameter of the connection channel 4), which can make the valve core 8 abut against the side wall of the first annular boss 6 or the second annular boss 7, thereby sealing the annular space, and eliminate the prior art mode in which the sealing ring is arranged in the circumferential direction of the valve core 8, and the sealing ring is always in contact with the inner wall of the connection channel 4, thereby prolonging the service life.

[0043] In the embodiment, the filter core assembly is provided with the cylinder assembly 1 and the valve core 8, which can ensure flexible switching of the water path, and the valve core 8 can axially slide in the connection channel 4 to switch between the first position and the second position, thereby effectively blocking or communicating different water paths, and ensure continuous water supply when the filter core is replaced or removed. The end face abutting sealing mode is adopted to avoid the sealing failure problem caused by friction and sharp edge scraping of the traditional O-shaped sealing ring.

[0044] In one embodiment, the side of the valve core 8 facing the first annular boss 6 is provided with a gasket 9, and in the second position, the gasket 9 abuts against the first annular boss 6 to block the annular space of the first annular boss 6.

[0049] It should be noted that the abutting portion 8001, the limiting portion 8002 and the guiding portion 8003 are configured in an integrated structure, which can enhance the structural strength and further prolong the service life. At the same time, the annular space of the second annular boss 7 can guide the guiding portion 8003, so as to ensure that the guiding portion 8003 can slide along the axial direction of the connecting channel 4.

[0050] Optionally, the bottom end of the limiting portion 8002 facing the first annular boss 6 can be provided with a limiting protrusion 8005 protruding in the circumferential direction of the limiting portion 8002, so that the limiting portion 8002 between the limiting structure and the abutting portion 8001 forms a necked structure, which limits the annular gasket 9 and ensures the stability of the first gasket 9.

[0051] Optionally, the peripheral surface of the guiding portion 8003 can be spaced apart along the circumferential direction and provided with a plurality of strip-shaped protrusions, the strip-shaped protrusions are in sliding fit with the annular space of the second annular boss 7, and the through grooves 8004 are formed between adjacent two strip-shaped protrusions for communicating the connecting channel 4 and the water outlet channel 3.

[0052] In this embodiment, the abutting portion 8001, the limiting portion 8002 and the guiding portion 8003 of the valve core 8 are reasonably designed, which not only ensures the effective plugging of the valve core 8 at different positions, but also realizes the flexible communication between the water outlet channel 3 and the connecting channel 4 through the sliding fit of the guiding portion 8003 with the second annular boss 7 and the arrangement of the through grooves 8004.

[0053] In one embodiment, a first spring 10 is further arranged in the water outlet channel 3, the first end of the first spring 10 is connected to the guiding portion 8003, the second end of the first spring 10 abuts against the inner wall of the water outlet channel 3, and the first spring 10 has a tendency to drive the abutting portion 8001 away from the second annular boss 7.

The first end of the first spring 10 is located in the annular space of the second annular boss 7, and the part of the guide portion 8003 facing the first spring 10 is provided in a tapered structure, which can fix the first end of the first spring 10.

[0055] In this embodiment, the first spring 10 is arranged so that the valve core 8 can automatically reset to the initial position, i.e. the second position, when not subjected to external force, thereby ensuring the continuous water supply function of the filter element assembly when the filter element is missing, and simplifying the operation of waterway switching.

[0059] In one embodiment, the one-way valve 11 includes a valve body 1101 and a valve cap 1102, the valve cap 1102 is connected to one end of the valve body 1101 facing the through hole 12, in the first position, the valve cap 1102 is separated from the through hole 12, and the valve body 1101 abuts the first end of the reversing channel 15, in the second position, the valve cap 1102 blocks the through hole 12.

[0060] Optionally, the valve cap 1102 is provided with a rubber valve cap 1102 or a silica gel valve cap 1102, and the size of the valve cap 1102 is larger than the size of the through hole 12, so that the valve cap 1102 can block the through hole 12.

[0061] It should be noted that the bonnet 1102 and the valve body 1101 are in a split structure, the valve body 1101 is provided with a limiting block 1103 at one end thereof towards the bonnet 1102, the cross section of the limiting block 1103 along the axis thereof is in a T-shaped structure, at the same time, the bonnet 1102 is provided with a limiting groove at one end thereof towards the valve body 1101, the limiting groove is adapted to the limiting block 1103, the limiting block 1103 and the limiting groove are in a clamping connection, thereby realizing the connection of the two.
