Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, and in particular to a shower head with a filter. Background Technology

[0002] Most showerheads on the market that offer filtration achieve their effect by installing an additional filter cartridge outside the showerhead. Replacing the filter cartridge requires tools for disassembly and installation, increasing the risk of water leakage. Furthermore, even with a filter cartridge and showerhead containing it (CN207734695U) that allows for relatively quick filter cartridge replacement, the inlet and outlet ports of this cartridge are located at two spaced-apart positions on the same end face. This means that the water flow, viewed longitudinally, is inside the cartridge, moving from one side to the other, which can easily lead to water pressure imbalance. Moreover, since showerheads are generally small, the corresponding filter cartridges are also small. Using two thin connecting posts for the inlet and outlet ports makes these posts prone to breakage, affecting filter replacement and usability. Utility Model Content

[0003] This invention provides a shower head with a filter, which can effectively solve the above problems.

[0004] This utility model is implemented as follows: A shower head with a filter, comprising: The main component has a water inlet, at least two water outlet channels, and a filter chamber. The filter chamber is disposed between the water inlet and the water outlet channels, and has an opening at one end away from the water inlet. A fixing part is provided at one end of the filter chamber. A filter element assembly is pluggably connected to the filter chamber and movably fixed to the fixing part. A flow channel is formed between the filter element assembly and the filter chamber. Water flows from the water inlet through the filter element assembly for filtration and then flows through the flow channel to any of the water outlet channels for water discharge.

[0005] As a further improvement, the inner wall of the filter chamber is provided with a first sealing surface and a second sealing surface that are far apart from each other. At least one first sealing ring and at least one second sealing ring are respectively provided at both ends of the filter element assembly. The first sealing ring corresponds to the first sealing surface, and the second sealing ring corresponds to the second sealing surface, so that the filter element assembly is sealed in the filter chamber.

[0006] As a further improvement, the filter element assembly includes a filter rod and a first knob detachably connected to the filter rod. The filter rod has spaced-apart filter media chambers, an inlet, and an outlet. The first knob is located at one end of the opening and closes one side of the filter media chamber. Water flows from the inlet through the inlet, through the filter media chamber, through the outlet, and into the flow channel.

[0007] As a further improvement, two of each of the first and second sealing rings are provided. The two first sealing rings are located on the outer wall surface of the first knob, and the two second sealing rings are located on the filter rod near the water inlet. The first sealing surface is located on the inner wall surface near the opening, and the second sealing surface is located on the inner wall surface near the water inlet. The water outlet is located on the side near the water inlet, thereby extending the flow length of the filter media chamber.

[0008] As a further improvement, the filter media chamber has two cavities, an inner and an outer, with the lower ends of the two cavities communicating with each other. The water inlet communicates with the inner cavity, and the water outlet communicates with the outer cavity. The second knob is located at one end of the opening to close the lower end of the filter media chamber.

[0009] As a further improvement, the inlet and the outlet are respectively located on different surfaces that are offset from each other, or the inlet and the outlet are respectively located on different surfaces that are at an angle to each other.

[0010] As a further improvement, the inlet and the outlet are located at the same end of the filter rod. The filter rod has a stepped surface with different outer diameters at the end near the inlet. The inlet is located on the first stepped surface, and the outlet is located on the second stepped surface. The first stepped surface is located above the second stepped surface, and the outer diameter of the first stepped surface is smaller than the outer diameter of the second stepped surface.

[0011] As a further improvement, at least two mutually spaced positioning platforms are provided on the outer side wall of the first knob, and a positioning groove corresponding to the positioning platform is provided on the inner side wall of the filter cavity. The positioning platform is movably disposed in the positioning groove, so that the filter rod is movably fixed in the filter cavity along with the first knob.

[0012] As a further improvement, the filter element assembly also includes a second knob, which is fixed to one end of the filter rod and detachably connected to the first knob. The second knob abuts against one end of the opening and closes the filter media chamber. A limiting handle protrudes from the end of the second knob away from the filter rod, and a handle protrudes from the surface of the end of the first knob away from the filter rod. A limiting groove is recessed on the inner side of the handle. When the first knob is placed on the second knob, the limiting handle is accommodated in the limiting groove. Alternatively, when the first knob is placed on the filter rod, the handle is operated to allow the positioning platform of the first knob to be movably positioned in the positioning groove.

[0013] As a further improvement, the main component includes a body, a fixed base disposed within the body, a ball head disposed at one end of the fixed base, a water distribution body disposed at the other end of the fixed base, and a water outlet structure movably connected to the water distribution body. The water inlet is disposed at the ball head, the filter chamber is disposed on the fixed base, and the water outlet channel is disposed on the fixed base, the water distribution body, and the water outlet structure.

[0014] The beneficial effects of this utility model are: 1) The filter cartridge assembly can be integrated into the shower head, and the filter cartridge assembly can be replaced after prolonged use. Replacement is quick and easy, without removing the shower head or using auxiliary tools; the filter cartridge assembly can be replaced simply by rotating it. This solves the problem of traditional methods requiring additional filter cartridges, specialized tools for disassembling and installing filter cartridges, or cumbersome replacement procedures, which increase the risk of water leakage. It saves time and effort, reduces the risk of water leakage, and frees up space occupied by additional filter cartridge assemblies; 2) The shower head can also perform filtration while... 3) The filter media chamber of the filter element assembly is set as an inner and outer cavity, with the inlet connected to the inner cavity and the outlet connected to the outer cavity, so that the water flow can flow from the inner cavity to the outer cavity, ensuring the balance of water pressure; 4) The inlet and outlet of the filter element assembly are set on stepped surfaces with different outer diameters, which is equivalent to the first stepped surface protruding upward from the surface of the second stepped surface to form a column structure. This can ensure that the outer diameter of the first stepped surface and the diameter of the inlet are guaranteed on the filter rod with limited size, preventing the column structure from breaking due to being too thin.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Reference Figures 1-6 As shown, a shower head with a filter includes a main body component 1 and a filter element component 2 that can be quickly plugged and unplugged into the main body component 1. When the filter element component 2 reaches the end of its service life and needs to be replaced, the shower head is not flushed, and the filter element component 2 is directly pulled out of the main body component 1, and then a new filter element component 2 is inserted into the main body component 1.

[0030] Example 1: refer to Figure 3As shown, the main component 1 has a water inlet 121, at least two water outlet channels 18, and a filter chamber 131. The filter chamber 131 is disposed between the water inlet 121 and the water outlet channels 18, and has an opening 132 at one end away from the water inlet 121. A fixing part is provided at one end of the filter chamber 131. The filter element assembly 2 is provided with a positioning part corresponding to the fixing part. When the filter element assembly 2 is inserted into the filter chamber 131, it is rotated to fix the positioning part to the fixing part. A flow channel 17 is formed between the filter element assembly 2 and the filter chamber 131. Water flows from the water inlet 121 through the filter element assembly 2 for filtration, and then flows through the flow channel 17 to either of the water outlet channels 18 for outlet. When the filter element assembly 2 needs to be replaced and is pulled out of the filter chamber 131, the water supply is disconnected, and the filter element assembly 2 is rotated to separate the positioning part from the fixing part, thus separating the filter element assembly 2 from the filter chamber 131.

[0031] When the filter element assembly 2 is inserted into the filter chamber 131, the filter element assembly 2 requires a sealed fit with the filter chamber 131. Specifically, the inner wall of the filter chamber 131 is provided with a first sealing surface and a second sealing surface that are far apart from each other. At least one first sealing ring 24 and at least one second sealing ring 25 are respectively provided at both ends of the filter element assembly 2. The first sealing ring 24 corresponds to the first sealing surface, and the second sealing ring 25 corresponds to the second sealing surface, so that the filter element assembly 2 is sealed in the filter chamber 131, thereby preventing the flow channel 17 from directly communicating with the water inlet 121 and the opening 132.

[0032] In this embodiment, the filter element assembly 2 includes a filter rod 23, a second knob 22 fixed to one end of the filter rod 23, and a first knob 21 detachably connected to the second knob 22. The filter rod 23 has a filter media cavity 233 spaced apart, an inlet 231, and an outlet 232. The outlet 232 is located near the inlet 231, thereby extending the flow length of the filter media cavity 233. The inlet 231 communicates with the inlet section 121, and the outlet 232 communicates with the flow channel 17. The filter media cavity 233 has inner and outer cavities, and the lower ends of the two cavities communicate with each other. The inlet 231 is located at the upper end of the inner cavity, and the outlet 232 is located at the upper end of the outer cavity. The second knob 22 is located at one end of the opening 132 and closes the lower end of the filter media cavity 233. Specifically, the filter rod 23 and the second knob 22 can be fixed by welding or by a threaded connection. Two first sealing rings 24 and two second sealing rings 25 are provided respectively. The two first sealing rings 24 are located on the outer wall surface of the first knob 21, and the two second sealing rings 25 are located on the filter rod 23 near the water inlet 121. The first sealing surface is located on the inner wall surface near the opening 132, and the second sealing surface is located on the inner wall surface near the water inlet 121. The first sealing ring 24 cooperates with the first sealing surface to seal the opening 132, and the second sealing ring 25 cooperates with the second sealing surface to seal the water inlet 231 of the filter rod 23. Water flows from the water inlet 121 to the water inlet 231, passes through the inner cavity of the filter media chamber 233 to the outer cavity of the filter media chamber 233 for filtration, flows to the water outlet 232, and then flows to the flow channel 17. In this embodiment, the first sealing element 24 and the second sealing element 25 can be either O-rings or Y-rings.

[0033] refer to Figure 5As shown, in this embodiment, the inlet 231 and the outlet 232 are located at the same end of the filter rod 23, but are offset on different surfaces. The filter rod 23 has two stepped surfaces with different upper and lower surfaces near the end of the inlet 231. The inlet 231 is located on the first stepped surface 231a, and the outlet 232 is located on the second stepped surface 232a. The first stepped surface 231a is located above the second stepped surface 232a, and the outer diameter of the first stepped surface 231a is smaller than the outer diameter of the second stepped surface 232a. Only two stepped surfaces are provided, which is equivalent to the first stepped surface 231a protruding upward from the surface of the second stepped surface 232a to form a columnar structure. This can ensure that the outer diameter of the first stepped surface 231a and the diameter of the inlet 231 are guaranteed on the filter rod 23 with limited size, and prevent the columnar structure from being too thin and breaking. In other embodiments, the inlet 231 and the outlet 232 can be respectively disposed on different surfaces at an angle to each other. For example, the inlet 231 is disposed on the upper surface, and the outlet 232 is disposed on the side surface near the end of the inlet 231. This can also extend the flow length of the filter media chamber 233, so that the water flow can be fully filtered.

[0034] refer to Figure 6As shown, at least two mutually spaced positioning platforms 211 are provided on the outer side wall of the first knob 21, thereby forming the positioning part. A positioning groove 133 corresponding to the positioning platform 211 is provided on the inner side wall of the filter chamber 131, thereby forming the fixing part. The positioning platform 211 is movably disposed within the positioning groove 133, allowing the filter rod 23 to be movably fixed within the filter chamber 131 along with the first knob 21. In this embodiment, the positioning platform 211 and the positioning groove 133 can be provided with a snap-fit ​​rotating structure that engages with each other. The positioning platform 211 is configured as a snap-fit ​​structure, and the positioning groove 133 is configured as a snap-slot structure. The snap-fit ​​structure enters from the snap-fit ​​opening of the snap-fit ​​structure and engages with the snap-fit ​​structure. Of course, in other embodiments, the positioning platform 211 and the positioning groove 133 can also be configured as threaded structures. For example, the positioning platform 211 can be configured as an external thread structure and the positioning groove 133 can be configured as an internal thread structure, so that the positioning platform 211 is fixed to the positioning groove 133, thereby connecting the first knob 21 to the fixed base 13. More specifically, the second knob 22 has a limiting handle 221 protruding from the end away from the filter rod 23, and the first knob 21 has a handle 212 protruding from the surface of the end away from the filter rod 23. The inner side of the handle 212 has a limiting groove 213. When the first knob 21 is placed on the second knob 22, the limiting handle 221 is accommodated in the limiting groove 213. By operating the handle 212, the first knob 21 is rotated and the second knob 22 is driven to rotate the filter rod 23. The positioning platform 211 then rotates in the positioning groove 133, so that the positioning platform 211 can be positioned in the positioning groove 133 or disengaged from the positioning groove 133. Because the filter rod 23 and the second knob 22 are fixedly connected as one unit, and the first knob 21 and the second knob 22 are detachably connected, when the filter element assembly 2 is replaced, after removing the filter element assembly 2, simply discard the filter rod 23 and the second knob 22, and then connect the first knob 21 to the new second knob 22 and the filter rod 23.

[0035] refer to Figure 2As shown, the main component 1 includes a body 11, a fixed base 13 disposed within the body 11, a ball head 12 disposed at one end of the fixed base 13, a water distributor 14 disposed at the other end of the fixed base 13, and a water outlet structure movably connected to the water distributor 14. The water inlet 121 is disposed at the ball head 12, the filter chamber 131 is disposed on the fixed base 13, and the water outlet channel 18 passes through the fixed base 13, the water distributor 14, and the water outlet structure. The water outlet structure includes a water outlet cover 15 and a decorative cover 16 covering the water outlet cover 15. Rotating the decorative cover 16 can cause relative movement between the water outlet cover 15 and the water distributor 14, thereby enabling the switching of multiple water outlet functions. Switching between multiple water outlet functions is existing technology and will not be elaborated upon here.

[0036] Reference Figure 4 As shown, water enters from the inlet 121 of the ball head 12, passes through the inlet 231 of the filter element assembly 2, is filtered by the filter media in the filter media chamber 233, flows from the outlet 232 of the filter element assembly 2 to the flow channel 17, and then flows out through the outlet hole of the outlet cover 15. (Refer to...) Figure 5 As shown, when the filter element assembly 2 is working, water flows from the inlet 231 into the inner cavity of the filter media chamber 233, flows through the lower end face of the filter media chamber 233 to the outer cavity of the filter media chamber 233, and then flows from the outlet 232 to the flow channel 17. After a period of use, the filtration effect of the filter element assembly 2 deteriorates, and the filter element assembly 2 can be replaced. Operate the handle 212 to rotate the filter element assembly 2, so that the positioning platform 211 is disengaged from the positioning groove 133 and the filter element assembly 2 is pulled down. To replace the filter element assembly 2, insert the filter element assembly 2 into the filter chamber 131 and operate the handle 212 to rotate the filter element assembly 2, so that the positioning platform 211 is engaged in the positioning groove 133.

[0037] Example 2: refer to Figures 7-10 As shown, the filter element assembly 2 includes a filter rod 23 and a first knob 21 fixed to the filter rod 23. The knob 21 is located at one end of the opening 132 and closes the lower end of the filter media chamber 233. Specifically, the filter rod 23 and the first knob 21 can be fixed by welding or by a threaded connection. However, here, the filter rod 23 and the first knob 21 are fixedly integrated, so when replacing the filter element assembly 2, after removing the filter element assembly 2, the first knob 21 and the filter rod 23 are discarded simultaneously, and a new filter element assembly 2 consisting of the first knob 21 and the filter rod 23 can be installed. Other structures and water flow patterns are the same as in Embodiment 1, and will not be described in detail here.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
