[0056] The present application will be described in detail below with reference to the accompanying drawings.

[0057] In order to solve the above technical problems, in combination with Figures 1-16As shown, the embodiment of the present application provides a shower head, which comprises a shell 1 and a cover 2, the shell 1 is provided with a water inlet 131, and the shell 1 and the cover 2 are detachably connected to form a filtering cavity 114, and a filter core 3 is accommodated in the filtering cavity 114, so that the filter core 3 can be replaced and cleaned by detaching the cover 2. The filter core 3 has a water inlet end 31 and a water outlet end 32, and unfiltered water flows into the water inlet 131 on the shell 1, reaches the cover 2, is blocked by the cover 2 and changes the flow direction, bends and enters the water inlet end 31 of the filter core 3, at this time, the cover 2 is only a component for blocking and guiding water flow, so when the cover 2 is detached, the main structure of the shell 1 is not affected, and the entire shower head does not need to be disassembled. Or preferably, the cover 2 is arranged substantially perpendicular to the water outlet direction of the water outlet end 32, a panel assembly 7 is arranged on the shell 1, and the cover 2 makes the filtered water flow out of the water outlet end 32, bend at the cover 2 and enter a shower cavity of the panel assembly 7, and finally spray out of a spray hole 71, so the cover 2 and the panel assembly 7 are independently arranged, the cover 2 is only a component for blocking and guiding water flow and is not located in a spray cavity 72 of the panel assembly 7, and the cover 2 does not need to open the panel assembly 7 when it is detached, so that the filter core 3 can be quickly and conveniently replaced and cleaned.

[0058] In an embodiment of the present application, in combination with Figure 2 Figure 3 , Figure 10 and Figure 16 As shown, the cover 2 comprises a first end wall 23 and a first side wall 24, the first side wall 24 is a circumferential side wall arranged around the first end wall 23, the first end wall 23 is arranged towards a port of the water inlet end 31 of the filter core 3, and the cover 2 is arranged spaced apart from the water inlet end 31 of the filter core 3, so that the first side wall 24 and the first end wall 23 form a first water passage 4 bent between the water inlet end 31 of the filter core 3, and the unfiltered water is conveyed from the first water passage 4 to the space between the cover 2 and the water inlet end 31 of the filter core 3 after entering the filtering cavity 114 from the water inlet 131, at this time, the first end wall 23 plays a blocking role to prevent the water flow from directly passing through, but guides the water flow to change the direction and enter the water inlet end 31 of the filter core 3. It can be understood that the first water passage 4 can be formed by arranging the filter core 3 and the end cover to be spaced apart, or the water flow can be directly conveyed by arranging a pipeline. In the present application, the water inlet pipe wall 13 is connected through the filter wall 11 and located close to the cover 2. In addition, the water inlet pipe wall 13 can also be directly communicated with the first side wall 24 of the cover 2, and the unfiltered water directly enters the space between the cover 2 and the water inlet end 31 through the first side wall 24.

[0059] In an embodiment of the present application, in combination with Figures 2-4As shown, the shell 1 comprises a filter wall 11, a water inlet pipe wall 13 and a mounting wall 12, the filter wall 11 is detachably connected with the cover 2 to form a filter cavity 114, the filter core 3 is located in the filter cavity 114, the water inlet pipe wall 13 is communicated with the filter wall 11, the water inlet 131 is arranged in the water inlet pipe wall 13, and the unfiltered water enters the filter cavity 114 through the water inlet 131 of the water inlet pipe wall 13. Optionally, the filter wall 11 is provided with an opening structure 1201 near one end of the water inlet end 31, the cover 2 is detachably connected with the opening structure 1201, and the first end wall 23 of the cover 2 is substantially perpendicular to the water inlet direction of the water inlet end 31, so that after the unfiltered water enters the filter cavity 114, it is blocked by the cover 2 and changes the flow direction, and under the guidance of the cover 2, it enters the water inlet end 31 of the filter core 3 to start the filtering process. By arranging the water inlet 131 in the water inlet pipe wall 13 instead of being directly connected with the cover 2, the interference of the water inlet 131 when the cover 2 is detached is avoided. When replacing or cleaning the filter core 3, the user only needs to detach the cover 2, without the need to disassemble the entire shell 1. The mounting wall 12 comprises an extension wall 121 and an outwardly extending wall 122, the extension wall 121 is arranged around the filter wall 11, and the outwardly extending wall 122 extends outwardly to form a mounting opening, and the panel assembly 7 is mounted on the mounting opening. The panel assembly 7 is adjacent to the water outlet end 32 of the filter core 3, facilitating the communication between the spray cavity 72 and the water outlet end 32, and the water is sprayed through the spray hole 71. In addition, the filter core 3 has a cavity 34, and the cavity 34 is suitable for filling filter cotton, activated carbon, gravel, ceramic filter core 34, fiber filter material or ion exchange resin and other filtering materials to filter fluid.

[0060] In an embodiment of the present application, in combination with Figure 2 As shown, the water inlet direction of the water inlet 131 is the water inlet direction of the water inlet pipe wall 13, and optionally, the water inlet direction is arranged at an angle with the axial direction of the filter core 3, preferably, an acute angle. When the unfiltered water enters the filter cavity 114 from the water inlet 131, it is forced to change the flow path into the first water passage 4 due to the blocking effect of the filter core 3, and finally enters the water inlet end 31 by detouring under the blocking of the cover 2. Through this arrangement, the volume of the filter cavity 114 can be reduced, thereby reducing the volume of the entire shower head. In the present application, a gap is left between the side wall of the filter core 3 and the filter wall 11 and the cover 2, so that when the unfiltered water enters the filter cavity 114 from the water inlet 131, it will surge in the gap, enter the water inlet end 31 through the cooperation of the filter core 3, the filter wall 11 and the cover 2. The arrangement of the gap can optimize the distribution and flow state of the water flow, so that the shower head can have a large water inflow.

[0061] In an embodiment of the present application, in combination with Figure 3 、 Figure 7 and Figure 8As shown, at least one first water passing hole 111 is formed on the filter wall 11, and at least one second water passing hole 73 is formed on the panel assembly 7, and the first water passing hole 111 selectively communicates with the second water passing hole 73. The water filtered by the filter element 3 first flows out from the water outlet end 32 of the filter element 3, and then sequentially passes through the first water passing hole 111 and the second water passing hole 73, and finally enters the spray cavity 72. The communication between the first water passing hole 111 and the second water passing hole 73 can further optimize the distribution of water flow, so as to avoid the situation that the water flow is too large or unevenly distributed when entering the spray cavity 72. In addition, by reasonably setting the number, position and size of the first water passing hole 111 and the second water passing hole 73, the water flow speed and flow can be accurately controlled, so as to improve the use effect and user experience of the shower head. In addition, in the present application, the second water passing hole 73 in communication with the first water passing hole 111 can be switched by rotating the panel assembly 7, and different second water passing holes 73 correspond to different spray cavities 72, so that the user can select different spray holes 71 to water by rotating the panel assembly 7, forming multiple water modes for the user to choose.

[0062] In an embodiment of the present application, in combination with Figure 1 and Figure 7 As shown, preferably, the filter wall 11 is provided in a hollow cylindrical structure, and the filter wall 11 comprises a second end wall 113 and a second side wall 112, and the second side wall 112 is a circumferential side wall. The second side wall 112 comprises a first end 1122 and a second end 1121, and the first end 1122 is provided in an open manner, and the cover 2 can be detachably plugged on the first end 1122, and the second end wall 113 is located on the second end 1121, so that the cover 2 and the second end wall 113 can jointly limit the two ends 33 of the filter element 3, so as to ensure the stable installation and accurate positioning of the filter element 3 in the filter cavity 114. When the user needs to replace or clean the filter element 3, only the cover 2 needs to be disassembled, without the need to disassemble the entire shell 1. It can be understood that the filter wall 11 can also be provided in other shapes, and in the present application, the filter element 3 is provided in a columnar structure, and the filter wall 11 is provided in a cylindrical structure in cooperation, and when the filter element 3 is provided in other states, the filter wall 11 can also change the shape, as long as the internal filter cavity 114 can be formed.

[0063] In an embodiment of the present application, in combination with Figure 3 As shown, the filtering direction of the filter element 3 is consistent with the water outlet direction of the panel assembly 7, and at this time the second end wall 113 is arranged close to the water outlet end 32 of the filter element 3. Therefore, preferably, the first water passing hole 111 is formed on the second end wall 113, and the panel assembly 7 is arranged in abutment with the second end wall 113, and at this time the first water passing hole 111 and the second water passing hole 73 are directly connected. Alternatively, the first water passing hole 111 can also be formed at the position of the second side wall 112 close to the panel assembly 7, and the first water passing hole 111 and the second water passing hole 73 can also be communicated by setting a pipeline.

[0064] In another embodiment of the present application, as shown in Figure 10 , Figure 14 and Figure 16 , the cover 2 comprises a first end wall 23 and a first side wall 24, the first side wall 24 being a circumferential side wall arranged around the first end wall 23, the first end wall 23 being arranged towards the port of the water outlet end 32 of the filter element 3, the cover 2 being arranged spaced apart from the water outlet end 32 of the filter element 3, so that the first side wall 24 and the first end wall 23 form a second water passage 5 bent between the water outlet end 32 of the filter element 3, the filtered water is conveyed from the second water passage 5 to the spray cavity 72 after passing through the water outlet end 32, at this time the first end wall 23 plays a blocking role to prevent the water flow from passing directly, but to guide the water flow to change direction. Similarly, the second water passage 5 can be formed by spacing between the filter element 3 and the cover 2, or by arranging a pipeline to directly convey the water flow. It can be understood that the second water passage 5 formed by the first side wall 24 and the first end wall 23 together provides a space for the water flow to buffer and turn. The water flow is bent in the passage, which can reduce the water flow speed and reduce the impact force of the water flow on the inner wall of the spray cavity 72, while making the water flow more evenly distributed, creating better conditions for the subsequent spraying process.

[0065] In an embodiment of the present application, as shown in Figure 10 , Figure 11 , Figure 14 , Figure 15 and Figure 16 , the filter wall 11 and the cover 2 are detachably connected to form a filter cavity 114, the cover 2 is adjacent to the water outlet end 32 of the filter element 3, and the first end wall 23 of the cover 2 is arranged substantially perpendicular to the water outlet direction of the water outlet end 32, so that the filtered water is blocked and changes direction by the cover 2 after entering the filter cavity 114, and enters the spray cavity 72 under the guidance of the cover 2; the mounting wall 12 extends outwardly around the filter wall 11 and is used to support and fix the panel assembly 7. The panel assembly 7 is tightly connected with the shell 1 through the mounting wall 12, so as to realize the stability and aesthetics of the overall structure. The design of the mounting wall 12 not only enhances the structural strength of the shell 1, but also provides a reliable mounting basis for the panel assembly 7, so that the panel assembly 7 can be firmly mounted on the shell 1, and the user can easily disassemble and maintain it.

[0066] In an embodiment of the present application, as shown in Figure 15 and Figure 16As shown, the filtering direction of the filter element 3 is consistent with the water outlet direction of the panel assembly 7, at this time, the panel assembly 7 is provided with an opening structure 1201, the cover 2 is embedded in the opening structure 1201 and detachably connected with the opening structure 1201, when the cover 2 is installed in the opening structure 1201, the first end wall 23 of the cover 2 blocks the water outlet end 32 of the filter element 3, at least one third water passing hole 231 can be provided on the first side wall 24 of the cover 2, the panel assembly 7 is provided with a gap or a water inlet channel relative to the third water passing hole 231, thereby being capable of conveying the filtered water into the spray cavity 72 of the panel assembly 7. When the filter element 3 needs to be replaced or cleaned, the cover 2 can be detached, at this time, the panel assembly 7 does not need to be opened as a whole, which is convenient and fast. It can be understood that the opening structure 1201 can also be provided on the water outlet end 32 of the filter element 3, the cover 2 is embedded in the panel assembly 7 and detachably connected with the water outlet end 32 of the filter element 3, which also facilitates the detachment of the cover 2.

[0067] In an embodiment of the present application, in combination with Figure 16 As shown, the water inlet pipe wall 13 is arranged along the filtering direction of the filter element 3, and the water inlet 131 is arranged in the water inlet pipe wall 13, so that the unfiltered water can directly flow into the water inlet end 31 of the filter element 3 after coming out of the water inlet 131, thereby ensuring the large-flow water inlet of the shower head.

[0068] In an embodiment of the present application, in combination with Figures 9-14 As shown, the filtering direction of the filter element 3 is substantially perpendicular to the water outlet direction of the panel assembly 7. It can be understood that at this time, the filter element 3 is vertically arranged, so that the filtering wall 11 forms a vertical approximately cylindrical structure, the filter element 3 is installed in the filtering wall 11, and the cover 2 is detachably arranged on the bottom end opening of the filtering wall 11, so that the filter element 3 can be replaced and cleaned by detaching the cover 2, thereby not needing to detach the entire shower head. The filtered water is folded back to the spray cavity 72 of the panel assembly 7 under the blockage of the cover 2. The vertically arranged cylindrical structure can provide sufficient installation space for the filter element 3 and can provide a buffer area for the water flow, so that the water flow can be further stabilized and uniformly distributed before entering the panel assembly 7.

[0069] In an embodiment of the present application, in combination with Figure 10 As shown, optionally, the cover 2 is located on the bottom end opening of the filtering wall 11, and the spray cavity 72 is located at the middle position of the panel assembly 7, the filter element 3 and the filtering wall 11 can be spaced apart to form a third water passing channel 6, after the filtered water is folded back under the blockage of the cover 2, that is, after passing through the second water passing channel 5, the filtered water enters the third water passing channel 6 and is conveyed to the vicinity of the spray cavity 72 through the backfolding of the third water passing channel 6. It can be understood that the third water passing channel 6 can also be arranged through a pipeline.

[0070] In an embodiment of the present application, in combination with Figures 10-12 andFigure 14 As shown, the spray cavity 72 is located in the middle of the panel assembly 7, and the second water passing hole 73 is also located in the middle of the panel assembly 7, so a water passing cavity 115 needs to be arranged above the filter element 3. The filtered water is transported into the water passing cavity 115 through the second water passing channel 5 and the third water passing channel 6, gathered in the water passing cavity 115, and then enters the first water passing hole 111, and then enters the second water passing hole 73 through the first water passing hole 111. The water passing cavity 115 is formed by the space left after the filter wall 11 is installed with the filter element 3. It can be understood that the water passing cavity 115 can also not be arranged.
