An embodiment of the utility model provides a filter core of water purifier to carry out depth filter to quality of water, the filter core includes casing 10, check valve 20 and gland 40, casing 10 one end has installation head 11, installation head 11 is equipped with recess 111, check valve 20 sets up in recess 111, gland 40 compresses tightly check valve 20, gland 40 is located installation head 11, and with the inner wall butt of installation head 11 or be close to the inner wall of installation head 11, and be equipped with spacing portion on the inner wall of installation head 11 or the lateral wall of gland 40.

The filter element of the water purifier comprises a shell 10, a one-way valve 20 and a gland 40, wherein the shell 10 is provided with a groove 111 at one end of a mounting head 11, the one-way valve 20 is arranged in the groove 111 to control the opening and closing of a water path, and the gland 40 is also arranged to press the one-way valve 20 to limit the axial movement of the one-way valve 20. Because the inner wall of the mounting head 11 or the side wall of the gland 40 is provided with the limiting part, the mounting head 11 limits the gland 40, and the poor welding effect caused by deviation of the gland 40 during welding is effectively avoided. Moreover, the gland 40 abuts against the inner wall of the mounting head 11 or is close to the inner wall of the mounting head 11, so that the coaxiality of the gland 40 and the shell 10 is ensured, the gland 40 axially limits the one-way valve 20 and the sealing ring 30, meanwhile, the shell 10 also radially limits the gland 40, the gland 40 is prevented from radially moving, and the deviation of the gland 40 is further effectively avoided. In addition, when the gland 40 is installed in the installation head 11, the limiting part can prevent the direct surface-to-surface contact between the gland 40 and the installation head 11, on one hand, the installation of the gland 40 is more convenient, and on the other hand, the damage to the shell 10 or the gland 40 during the installation is avoided.

It should be noted that, when the water purifier is in normal use, the one-way valve 20 is opened to connect the internal and external water paths of the filter element, so that the filtered water can be output to meet different water requirements, such as domestic water, drinking water, and the like; when the filter element is disassembled and assembled, the one-way valve 20 is closed to isolate the inner and outer water paths of the filter element, so that the phenomenon that the residual water in the filter element flows out to wet the external environment or other structures of the water purifier is avoided, and inconvenience is brought to users or even the water purifier is damaged.

In the present embodiment, the sidewall of the pressing cover 40 is provided with a position-limiting portion, and the position-limiting portion extends from the bottom of the pressing cover 40 to the top of the pressing cover 40. Because the limiting part extends from the bottom of the gland 40 to the top of the gland 40, the direct contact between the gland 40 and the shell 10 and the contact between the gland 40 and the shell 10 through the limiting part in a larger area are avoided, and when the welding operation of the gland 40 is carried out, the upper end of the gland 40 is ensured not to deviate while the lower end of the gland 40 is ensured to be normal, so that the welding effect of the gland 40 is effectively ensured. And the limiting part is positioned on the side wall of the gland 40, so that the production and the processing are more convenient. Of course, in other embodiments, the inner wall of the mounting head 11 may be provided with a limiting portion, and the length of the limiting portion is not limited.

In the present embodiment, the stopper is a stopper rib 41. By adopting the limiting ribs 41, the cost is lower, and the production and the processing are convenient. Of course, in other embodiments, the limiting portion is not limited to the limiting rib 41, and may be a protrusion, a bump, or the like.

Further, in the present embodiment, the longitudinal direction of the stopper rib 41 is parallel to the axial direction of the gland 40. So, spacing effect of the spacing muscle 41 of assurance that on the one hand can the preferred avoids gland 40 to take place the off normal when the welding, and on the other hand is convenient for gland 40's integrated into one piece processing, reduces the processing cost.

In this embodiment, the length of the position limiting rib 41 is less than 0.6 mm. Because the length of spacing muscle 41 is less, not only can avoid gland 40 to take place the off normal when the welding, can avoid moreover because the length overlength of spacing muscle 41 for the clearance between gland 40 and casing 10 is great, influences the whole aesthetic property of filter core.

In the present embodiment, the plurality of stopper ribs 41 are uniformly arranged around the axis of the gland 40. Because a plurality of spacing muscle 41 on the gland 40 are the axisymmetric evenly distributed, when welding gland 40, a circumference of gland 40 passes through spacing muscle 41 and casing 10 even contact to make gland 40 better cooperate with casing 10, effectively avoid gland 40 to take place the off normal when the welding.

Further, in the present embodiment, the number of the limiting ribs 41 is at least four. Specifically, in the present embodiment, the number of the limiting ribs 41 is eight, and the eight limiting ribs 41 are uniformly arranged around the axis of the gland 40, so as to ensure the coaxiality of the gland 40 and the housing 10, and further prevent the gland 40 from deviating when the gland 40 is subjected to ultrasonic welding. Of course, in other embodiments, the number of the limiting ribs 41 is not limited to eight, and may also be five, six, seven, and the like, and specifically may be set according to actual needs.

In this embodiment, the filter element further includes a sealing ring 30, the sealing ring 30 is located between the check valve 20 and the pressing cover 40, the plurality of grooves 111, the plurality of check valves 20 and the plurality of sealing rings 30 are provided, the grooves 111, the plurality of check valves 20 and the plurality of sealing rings 30 are correspondingly arranged one by one, and the pressing cover 40 presses the plurality of check valves 20 and is provided with a plurality of water inlets and water outlets 42 facing the grooves 111 one by one. The water inlet and outlet 42 on the gland 40 can realize the communication between the filtering channel in the filter element and the water channel in the water purifier, when in normal use, the water flow can flow into the filter element through the water inlet and outlet 42, and flows out through the water inlet and outlet 42 after the filter element is filtered to output treated water, and at least one of the water inlet and outlet 42 is a water inlet and one is a water outlet. In addition, the sealing ring 30 is arranged, so that the water path is sealed, and water leakage is avoided.

In the present embodiment, the opening of the water inlet/outlet port 42 is provided with a chamfer 421. Specifically, in the present embodiment, the rounding process is performed at the orifice circumference of the front face of the gland 40. The chamfer 421 is arranged at the hole of the water inlet/outlet 42, so that on one hand, the guide effect can be achieved during assembly, the pressing cover 40 is convenient to mount, and on the other hand, the whole filter element looks more beautiful.

In this embodiment, the back surface of the gland 40 further has a rib 43 capable of welding the gland 40 to the mounting head 11. Specifically, in the present embodiment, a plurality of ribs 43 are provided on the back surface of the gland 40, and a rib 43 is provided at each water inlet/outlet 42 for ultrasonic welding, so as to connect the gland 40 to the mounting head 11. In addition, in the present embodiment, the back surface of the gland 40 further has a support rib to support the gland 40 and ensure that the gland 40 presses the check valve 20.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
