Description

Technical Field

[0001] The utility model relates to the technical field of water purifier bottle caps, in particular to an L-shaped pre-treatment device for a water purifier Background Art

[0002] The filter bottle of a water purifier is an important component in the water purifier, mainly used to hold the filter element and filter the water quality to prevent secondary pollution of the water source. It is made of materials such as PP and ABS plastics, and its structure includes a filter bottle cap, a bottle body and an internal filter element structure; in existing water purifiers, the filter bottle cap already has a three-way structure, such as the utility model patent with the patent number CN217961613U and the patent name "A multi-in and multi-out three-way filter bottle cap"; however, the internal space of some water purifiers is limited, and the installation space of such ordinary three-way structures is restricted. Therefore, only the method of installing a single filter bottle cap separately can be forced. This method has a high cost, and it takes time and effort to connect and fix in a narrow space. Summary of the Utility Model

[0003] In order to solve the technical problem that the existing ordinary three-way filter bottle cap cannot be installed due to the limitation of the internal space of the water purifier, and only the method of installing separately has to be adopted, which increases the cost and takes time and effort, the utility model provides an L-shaped pre-treatment device for a water purifier.

[0004] The technical solution of the utility model is realized through the following scheme: An L-shaped pre-treatment device for a water purifier includes a first filter bottle cap, a second filter bottle cap and a third filter bottle cap connected in series in sequence; the first filter bottle cap, the second filter bottle cap and the third filter bottle cap are of an integral structure; a first filter water pipeline is integrally arranged on the first filter bottle cap and the second filter bottle cap; a second filter water pipeline is integrally arranged on the second filter bottle cap and the third filter bottle cap; first filter water hole groups, second filter water hole groups and third filter water hole groups are respectively arranged on the first filter bottle cap, the second filter bottle cap and the third filter bottle cap; it is characterized in that: the first filter bottle cap and the second filter bottle cap are arranged along a first direction; the second filter bottle cap and the third filter bottle cap are arranged along a second direction, and the first direction intersects with the second direction; the first filter water hole group communicates with the first filter water pipeline; the second filter water hole group communicates with the first filter water pipeline and the second filter water pipeline; the third filter water hole group communicates with the second filter water pipeline.

[0005] By using the above technical solution, the structure of the original product is designed, and the position of the original three-way filter bottle caps arranged in parallel in sequence is adjusted, so as to reduce the axial occupied space of the filter bottle cap. Under the condition of meeting the installation space of a small-capacity water purifier, the radial width is increased, which can not only avoid the increase in the installation cost of a single filter bottle cap, but also reduce the installation and connection difficulty of each module with the installation structure of the three-way structure, and is convenient for installation and use.

[0006] Preferably, the angle between the first direction and the second direction is 90°.

[0007] Preferably, the second water filter hole group includes a second water inlet hole and a second water outlet hole, the second water inlet hole is connected to the first water filter pipeline; the second water outlet hole is connected to the second water filter pipeline.

[0008] By using the above technical solution, different from the original structural design, due to the non-connected structural design of the first water filter pipeline and the second water filter pipeline, there is no need to add a second blocking hole.

[0009] Preferably, the first water filter hole group includes a first water inlet hole, a first water outlet hole and a first blocking hole; the first water inlet hole, the first water outlet hole and the first blocking hole are respectively connected to the first water filter pipeline; the first blocking hole is located between the first water inlet hole and the first water outlet hole.

[0010] By using the above technical scheme, the first water inlet hole is used to infuse the water in the first water filter pipeline into the filter bottle under the first filter bottle cover; the first water outlet hole is used to allow the water in the filter bottle filtered by the filter element to enter the secondary filtration process through the first water filter pipeline, and the first blocking hole is used to block the first water inlet hole and the second water outlet hole, so as to achieve the purpose of water filtration.

[0011] Preferably, the first water filtering hole group and the third water filtering hole group have the same structure.

[0012] Preferably, a water inlet is provided at one end of the first water filter pipeline away from the second filter bottle cover.

[0013] Preferably, a water outlet is provided at one end of the second water filter pipeline away from the second filter bottle cover.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The utility model provides an L-shaped pre-treatment device for a water purifier. By structurally designing the original product, the positions of the original triple filter bottle covers arranged in parallel are adjusted, thereby reducing the axial space occupied by the filter bottle covers. While meeting the installation space of a small-capacity water purifier, the radial width is increased, which can avoid the increase in the installation cost of a single filter bottle cover. At the same time, the triple installation structure reduces the difficulty of installing and connecting each module, making it convenient to install and use.

[0016] 2. Furthermore, the first water inlet hole is used to infuse the water in the first water filter pipeline into the filter bottle under the first filter bottle cover; the first water outlet hole is used to allow the water in the filter bottle filtered by the filter element to enter the secondary filtration process through the first water filter pipeline, and the first blocking hole is used to block the first water inlet hole and the second water outlet hole to achieve the purpose of water filtration.

[0017] 3. Again, different from the original structural design, due to the non-connected structural design of the first filter water pipeline and the second filter water pipeline, there is no need to add a second blocking hole anymore. BRIEF DESCRIPTION OF THE DRAWINGS
