Abstract

A water filter with dual mounting specifications comprises a filter shell surrounding to define a filtering space with an end wall, and a mounting unit. The mounting unit is configured on the end wall, and comprises a plurality of mounting bases configured around a center point of the end wall, a plurality of first mounting holes, and a plurality of second mounting holes. Each of the mounting bases is configured with a first mounting hole and a second mounting hole. The first mounting hole is located away from the center point than the second mounting hole. The line connecting the centers of the first mounting holes defines a first span, and the line connecting the centers of the second mounting holes defines a second span less than the first span. The present invention employs the configuration of these first and second mounting holes to provide two mounting specifications and achieve the effects of cost saving and convenient usage.

Description

Water filter with dual mounting specifications

The present invention relates to a water filter, and more particularly to a water filter having a dual installation specification.

Referring to Figure 1, a water filter 1 of the size that is common in the market is commonly used in general drinking water systems, and the water filter includes a plurality of side-by-side locks on a mounting plate (not shown). The filter housing 11 includes a filter cartridge 111 and a filter cover 112 connected to the filter cartridge 111. The filter cover 112 has a plurality of spaced apart mounting holes 113 for mounting holes. 113 respectively lock each filter housing 11 to the mounting plate (not shown).

Referring to Fig. 2, a water filter 2 belonging to the European standard is commonly used in a water filtration system for industrial water. The European water filter 2 is similar in composition to the US water filter 1, and the main difference is that The filter housing 21 of the European water filter 2 must be heavy-duty in order to handle a large amount of industrial water, so that by increasing the spacing between the mounting holes 213, the weighted filter housing 21 can be stably loaded, thereby enabling the manufacturer. In order to meet the water demand of different users, it is necessary to manufacture two different specifications of products, which in turn leads to an increase in manufacturing costs and inconvenience to users.

Accordingly, it is an object of the present invention to provide a water filter having dual installation specifications that is cost effective and convenient to use.

Thus, the present invention has a dual installation size water filter comprising a filter housing defining a filter space and a mounting unit.

The filter housing includes an end wall, a water inlet channel and a water outlet channel, and the water inlet channel and the outlet channel communicate with the filtering space and the outside.

The mounting unit is disposed on the end wall and includes a plurality of mounting bases disposed around a center point of the end wall, a plurality of first mounting holes, and a plurality of second mounting holes.

Each of the mounting bases is provided with a first mounting hole and a second mounting hole, and the first mounting hole is away from the center point than the second mounting hole, and a line connecting the centers of the first mounting holes constitutes a first A span size, the line connecting the centers of the second mounting holes constitutes a second span size that is smaller than the first span size.

The effect of the invention is that the arrangement of the first mounting holes and the second mounting holes can simultaneously provide the user with the option of double mounting specifications, thereby achieving cost saving and convenient use.

Other features and advantages of the present invention will be apparent from the embodiments of the present invention. FIG. 1 is a perspective view illustrating a conventional water filter; FIG. 2 is a perspective view illustrating a conventional An European water filter; FIG. 3 is a perspective view showing an embodiment of the water filter of the present invention having a dual installation specification; Figure 4 is a cross-sectional view showing the embodiment; Figure 5 is a plan view showing a mounting unit of the embodiment; and Figure 6 is a cross-sectional view taken along line VI-VI of Figure 5, illustrating the mounting of the embodiment a first mounting hole of the unit and a second mounting hole.

Referring to Figures 3, 4 and 5, an embodiment of the water filter of the present invention having a dual installation specification includes a filter housing 3 and a mounting unit 4 defining a filter space 31.

The filter housing 3 includes a filter cartridge 32 and a filter cover 33 connected to the filter cartridge 32. The filter cover 33 has an end wall 331 , a water inlet passage 332 and a water outlet passage 333 . The water inlet passage 332 and the inlet The outlet flow passage 333 communicates the filtration space 31 with the outside. In the present embodiment, the outer surface of the end wall 331 has an upwardly convex circular arc shape from a peripheral edge thereof toward a center point 334, and there is no problem of water accumulation.

It is worth mentioning that the filter housing 3 is not limited to being composed of the filter cartridge 32 and the filter cover 33, and may be composed of three or more components, and does not affect the efficacy of the present invention.

The mounting unit 4 is disposed on the end wall 331 and includes four mounting bases 41 disposed around the center point 334 of the end wall 331 , four first mounting holes 42 , and four second mounting holes 43 .

Each of the mounting bases 41 is provided with a first mounting hole 42 and a second mounting hole 43 , and the first mounting hole 42 is away from the center point 334 than the second mounting hole 43 . The line connecting the centers of the first mounting holes 42 constitutes a first span size L1 × W1, and the center of the second mounting holes 43 The line constitutes a second span size L2 x W2 that is smaller than the first span size L1 x W1. The filter housing 3 is adapted to lock the first mounting holes 42 when the mounting plate (not shown) of the European standard system is matched, and the filter housing 3 is matched with a mounting plate (not shown) of the US standard system. It is then suitable for locking the second mounting holes 43.

In the present embodiment, the mounting bases 41 are integrally formed upwardly from the end wall 331 of the filter cover 33, and the structural strength and the fullness of the injection material are superior to those of the conventional filter cover 112 (see FIG. 1) The mounting holes 113 are joined only by thin ribs. The geometrically symmetric centers of the first mounting holes 42 and the geometrically symmetric centers of the second mounting holes 43 substantially fall on the center point 334, so that the water inlet channels 332 and the water flow path 333 are oriented. It will not change due to the European system or the US system.

Referring to FIG. 6, in order to improve the stability of the mounting, the length of the first mounting holes 42 is greater than the length of the second mounting holes 43, and if the diameter of the first mounting holes 42 is too large, The longer length may cause the structure of the mounting base 41 to be weak. Therefore, the apertures of the first mounting holes 42 are designed to be smaller than the apertures of the second mounting holes 43, and conversely, the end wall 331 is limited. The circular arc-shaped outer surface, although the length of the second mounting holes 43 is smaller than the length of the first mounting holes 42, the mounting stability is also improved by the large hole diameter, and therefore, The first mounting hole 42 and the second mounting holes 43 can achieve a stable supporting effect by the combination of the aperture and the length thereof.

In summary, the present invention provides the user with two different mounting specifications at a time by providing the first mounting holes 42 and the second mounting holes 43 having different pitches to the filter cover 3 at the same time. Reaching savings The cost and the effect of ease of use are indeed achieved by the object of the present invention.

However, the above is only the embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and the patent specification of the present invention are still It is within the scope of the patent of the present invention.
