Description

A variety of filter heads can be used

This creation is about the technical field of a filter device, in particular a water collection head that can use a variety of filter core specifications.

According to the conventional filter structure, such as the "filter structure improvement" (or the figure 7) of the Chinese Patent Publication No. M455546, the utility model generally comprises a water dividing seat 91 and a set of cylinders disposed on the water dividing seat 91. 92. A double-opening filter core 81 standing on the water dividing seat 91 and a limiting double-opening filter core 81 are used for limiting the limiting rod 93. The center of the water dividing seat 91 has a limiting tube 912 that communicates with the water outlet 911. The double-opening filter core 81 is disposed at one end and is limited to the bottom end of the double-opening filter core 81 through the limiting tube 912.

In the conventional structural design, although the benefits of filtering the water source can be achieved, there are still some defects in the implementation, for example:

1. Please refer to Fig. 7, the double-opening filter core 81 structure has an axial hole top and bottom through shaft hole 811, and the shaft hole 811 is sleeved on the outer circumference of the limiting tube 912, so that the double opening type The filter core 81 is erected on the water dividing seat 91. Therefore, it is necessary for the limit tube 912 of the water dividing seat 91 to match the hole diameter of the shaft hole 811 of the double-open type filter core 81, so that the size is fixed, and when facing the hole diameter of the different shaft hole 811, only In addition, finding a matching water dividing seat 91 is very troublesome.

2. In addition, when the conventional water filter is implemented, the limit tube of the water separator 91 912, in order to be able to penetrate the shaft hole 811 of the double-open type filter core 81, so that the diameter of the limiting tube 912 itself is necessarily smaller than the shaft hole 811, and the water discharge amount is limited by the limiting tube 912.

3. Please refer to Figure 8, the single-open type filter core 82 structure, There is an insertion section 821 (water outlet end), and a plurality of O-rings 822 are sleeved on the outer circumference of the insertion section 821. During installation, the insertion section 821 and the O-ring 822 are inserted into the inner circumference of the limiting tube 912, and the inner diameter surface of the limiting tube 912 is pressed to complete the single-opening filter core 82. However, the insertion section 821 (outlet end) of the single-open type filter core 82 and the shaft hole 811 of the double-open type filter core 81 are different in size, and the water dividing seat 91 cannot be integrally applied.

Therefore, the conventional water divider 91 can not respond to different forms of filtration. The heart (single-open type or double-open type) is used in combination with the double-open type filter core 81, but the shaft hole 811 has a different aperture. This led to the lack of many scale diseases in the production of the conventional water trap 91. The job is how to overcome the general problems of the filter water filter and the lack of water volume, which is obviously an improvement of the industry.

In view of the above problems and shortcomings of the prior art, one of the purposes of this creation is to achieve the general demand for the filter through the design and improvement of the structure, and it is not limited to the amount of shrinkage.

In order to achieve the above objectives, this creation proposes a variety of filters that can be used. The heart-sized water collecting head comprises a base, an outer cover stacked on the base, a collar ring for restraining the base and the outer cover, a shaft disposed on the base and accommodated in the outer cover, and a shaft attached to the shaft An elastic member on the outer periphery and a limiting member screwed on the top end of the shaft. The base has a base body, two inner and outer water chambers formed on the base body and separated by a surrounding wall; the inner water chamber has a hole diameter slightly larger than a single open type filter core insertion section (water outlet end). The elastic element is selected from a coil spring having a slightly elliptical profile and is sleeved on the outer circumference of the shaft. If it is a structure, it can provide different filter core specifications (single open or double open type) and the need for filter guides under the premise of unlimited water volume.
