Detailed ways

The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the embodiments of the present utility model, and should not be understood as a limitation to the present utility model.

As shown in FIGS. 1 to 3, an embodiment of the present invention provides a filter assembly 600 including a filter tray 610 and a filter 620.

The filter tray 610 includes a bottom frame 611 and a support ring 612. The connection between the bottom frame 611 and the support ring 612 may be integrally formed, such as injection molding, die-casting or forging.

The bottom frame 611 includes a bottom plate 6111 and a supporting wall 6112. The supporting wall 6112 surrounds the periphery of the bottom plate 6111 and extends upward. Generally, when the filter tray 610 is installed in the portable water feeder, it is portable When the water feeder is placed vertically, the bottom plate 6111 is in a horizontal state, and the supporting wall 6112 is in a vertical state. In addition, the supporting wall 6112 and the bottom plate 6111 jointly enclose a filter element installation cavity 6113, and the filter element installation cavity 6113 can limit the filter element 620 contained therein. The filter element 620 is accommodated in the filter element installation cavity 6113. A number of filter holes 6114 are provided on the bottom plate 6111. The filter holes 6114 may be arranged at even intervals along the ring, and the shape of the filter holes 6114 may be a regular shape or an irregular shape.

The support ring 612 is arranged above the bottom frame 611, and the support ring 612 is connected to the top of the support wall 6112 and extends in a horizontal direction facing away from the filter installation cavity 6113. The support ring can be erected at a specific position in the portable water feeder. First, ensure that the installation of the filter tray 610 is completed.

In another embodiment of the present invention, as shown in FIGS. 1 to 3, the central portion of the bottom plate 6111 of the provided filter assembly 600 is provided with a central hole 6115 with a diameter of 13 mm to 17 mm. Specifically, the central hole 6115 is set to allow water to pass through on the one hand, and on the other hand, the bottom plate 6111 can be manipulated by reaching into it with a finger to realize the loading and unloading of the filter tray 610, thus facilitating the installation and installation of the filter tray 610. Disassemble. Specifically, the aperture of the central hole 6115 can be 13mm, 14mm, 15mm, 16mm or 17mm, etc. This size design avoids that the aperture of the central hole 6115 is too large to affect the support of the bottom plate 6111 to the filter 620, and at the same time, it will not If it is too small, it affects the penetration of the fingers, which not only ensures that the bottom plate 6111 plays its supporting role, but also facilitates its assembly and disassembly.

In another embodiment of the present invention, as shown in FIGS. 1 to 3, the inner wall of the central hole 6115 of the filter assembly 600 is provided with a bottom edge and a top edge that smoothly transition to the central hole 6115 The arc surface 6116. Specifically, the arc surface 6116 provided on the inner wall of the central hole 6115 is a rounded structure, which can chamfer the corner structure of the bottom edge of the inner wall of the central hole 6115 and the corner structure of the top edge to form an arc surface. When the user inserts a finger into the central hole 6115 and pulls the bottom plate 6111, the contact between the finger and the arc surface 6116 is smooth, which reduces the discomfort of the finger and improves the comfort of use.

In another embodiment of the present invention, as shown in FIGS. 1 to 3, the filter holes 6114 of the filter assembly 600 are provided in a strip structure, and the filter holes 6114 in a strip structure are formed by the bottom plate 6111. Extend to the supporting wall 6112. Specifically, the filter holes 6114 are arranged in a strip structure and extended to the supporting wall 6112, so as to increase the effective filtering area of the entire filter tray 610 and improve the filtering effect of the water flow.

The width of the filter hole 6114 in a strip structure gradually increases from the direction from the bottom plate 6111 to the supporting wall 6112. Specifically, the width of the filter holes 6114 of the strip structure on the bottom plate 6111 is smaller than the width of the position on the support wall 6112, and along the sequence from the bottom plate 6111 to the support wall 6112, the filter holes of the strip structure The width of 6114 gradually increases to increase the filtering speed of the water flow.

The long wall surface of the filter hole 6114 in a strip structure is an inclined curved surface. Specifically, the long wall surface in the filter hole 6114 is designed as an inclined curved surface, so that the water flow passing therethrough can be guided through the inclined curved surface to allow the water flow to flow more smoothly and improve the water outlet effect.

In another embodiment of the present invention, as shown in FIGS. 1 to 3, the long wall surface of the filter hole 6114 in the strip structure of the filter assembly 600 provided is an inclined curved surface. Specifically, the long wall surface in the filter hole 6114 is designed as an inclined curved surface, so that the water flow passing therethrough can be guided through the inclined curved surface to allow the water flow to flow more smoothly and improve the water outlet effect.

The outer end of the support ring 612 is provided with a plurality of annular protrusions 6121 arranged at equal intervals. Specifically, the arrangement of the protrusion 6121 can facilitate the clamping of the support ring 612 on the installation cover 200, which is beneficial to improve the stability of the installation of the filter tray 610. Further, the number of the protrusions 6121 can be four, six, eight, etc.
