Description

Technical Field

[0001] This utility model relates to the field of filters, and more particularly to a concealed filter. Background Technology

[0002] Tap water used in daily life contains varying degrees of impurities. Sometimes, we find that showerheads in the bathroom become clogged with impurities after a period of use, causing the water flow to be uneven and the direction of the water flow to be skewed. Furthermore, long-term use of tap water containing impurities may have varying degrees of impact on skin health, especially for people with sensitive or fragile skin. Currently, most existing showerhead water supply pipes are concealed, and these pipes only have a water flow distribution function, lacking a filtration module. They cannot directly filter impurities or purify the water. Traditional filtration devices, on the other hand, are exposed, connected to pipes on the exterior wall, or integrated into the showerhead. These exposed filtration devices cannot meet the requirements of compactness and concealment. Utility Model Content

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] refer to Figures 1 to 3 In some embodiments, the concealed filter kit includes: a filter element 2; and a housing 1, at least partially embedded in a wall 10. The filter element 2 is detachably installed within the housing 1. The housing 1 has an inlet 111 and an outlet 112. The inlet 111 is connected to a pipe 9 inside the wall 10, and water in the pipe 9 flows from the inlet 111 through the filter element 2 to the outlet 112. The outlet 112 can be connected to a shower pipe (not shown), etc. Figure 1 As shown, the left side of the wall 10 represents the interior of the wall 10, and the right side of the wall 10 represents the exterior of the wall 10. The filter kit is installed by pre-embedding, resulting in a compact installation structure and a concealed, aesthetically pleasing layout.

[0025] refer to Figures 1 to 3 In some embodiments, the housing 1 further includes a main body base 11 and a maintenance module 12. The main body base 11 and the maintenance module 12 are sealed together. The inlet 111 and the outlet 112 are located on the main body base 11, which is located inside the wall 10. The maintenance module 12 is at least partially located outside the wall 10, for maintaining the filter element 2 outside the wall 10. The design of the maintenance module 12 allows for maintenance and replacement of the filter element 2 without damaging the wall 10, thus combining the aesthetics and practicality of the concealed filter kit.

[0026] refer to Figure 1 In some embodiments, the maintenance module 12 includes a cylinder 121 and an end cap 122. The cylinder 121 has a maintenance port 123, and the end cap 122 is detachably installed on the maintenance port 123. In use, the end cap 122 is opened, and the filter element 2 to be replaced is rotated off through the maintenance port 123. The new filter element 2 is then installed into the housing 1 through the maintenance port 123 and secured with a rotating buckle. The end cap 122 is then installed back onto the maintenance port 123 to seal the housing 1. The maintenance port facilitates the inspection and maintenance of the installed filter, avoids dismantling the wall for maintenance, and reduces operating costs.

[0027] refer to Figure 1 In some embodiments, at least two threaded seats 124 are respectively provided on the outer ring of the contact surface of the main body 11 and the cylinder 121 for fastening the main body 11 and the cylinder 121 together with nuts 8. During pre-embedding, the main body 11 can be first connected to the pipe 9 inside the wall 10, and after adjusting the installation position, the cylinder 121 can be fixedly connected to the main body 11 to seal the wall surface, making the installation process convenient. Two, three, or four pairs of threaded seats 124 can be provided, depending on different fixing requirements.

[0028] refer to Figures 1 to 3 In some embodiments, an indicator cover 3 is rotatably provided on the outer side of the end cap 122, and the indicator cover 3 is marked with a month number. During daily use of the concealed filter, the filter element 2 needs to be replaced regularly to ensure the quality of daily water use. If the filter element 2 is not replaced for a long time, not only will the water quality deteriorate, but the water output may also decrease due to excessive accumulation of impurities inside the filter element 2, affecting the user experience. The indicator cover 3 can be rotated to the corresponding month to record the replacement month of the filter element 2, allowing the filter element 2 to be replaced every 1 to 3 months to ensure water quality.

[0029] refer to Figures 1 to 3In some embodiments, a switch 4 is also included, which is connected to the end cap 122 and used to rotate and open the end cap 122. The design of the switch 4 makes it convenient for ordinary users to manually unscrew the end cap 122 without the aid of other tools, making it more convenient and time-saving each time the filter element 2 is replaced.

[0030] refer to Figure 1 In some embodiments, the maintenance module 12 is provided with a first set of sealing rings 5, which are located at the connection between the main body 11 and the maintenance module 12. In this embodiment, there are two first set of sealing rings 5, which are used to increase the sealing between the main body 11 and the maintenance module 12 and prevent water leakage.

[0031] refer to Figure 1 In some embodiments, the maintenance module 12 is provided with a cylinder body sleeve 126 and a second set of sealing rings 6. The cylinder body sleeve 126 is located outside the cylinder body 121, covering the cylinder body 121, and the second set of sealing rings 6 is located between the cylinder body 121 and the cylinder body sleeve 126. In this embodiment, there are three second set of sealing rings 6, which are used to increase the sealing between the cylinder body sleeve 126 and the cylinder body 121 and prevent water from leaking outward from the wall 10.

[0032] refer to Figure 1 In some embodiments, the end cap 122 is provided with a third set of sealing rings 7, which are located at the connection between the end cap 122 and the cylinder body 121. In this embodiment, there are two third set of sealing rings 7, which are used to increase the sealing between the end cap 122 and the cylinder body 121 and prevent water from leaking out of the cylinder body 121.

[0033] In some embodiments, the filter element 2 includes multiple physical filtration layers, which may include PP cotton, a coarse filter layer, an activated carbon adsorption layer, an ion exchange resin layer, etc. Through a series design, it can effectively intercept particulate impurities, adsorb residual chlorine, and soften water.

[0034] The concealed filter kit of this utility model, by being pre-embedded in the wall 10, can meet the requirements of compact structure and concealment. It is equipped with an inspection port to achieve maintenance without dismantling the wall, and the maintenance and replacement of the filter element is very convenient. The multi-layer physical filtration layer in the filter element can also achieve high-efficiency filtration.
