[0028] This utility model provides a couple's shower head, which mainly includes a top spray and a shower head. The top spray can be fixed on the wall, and the shower head can be detachably connected to the top spray. The shower head and the top spray can be combined to form a larger water outlet panel.

[0029] Referring to the accompanying drawings, a filtered couple's shower head includes a shower head 10 and a top spray 20. The top spray has a groove 21 with its opening facing downwards. A filter element can be inserted into the groove from bottom to top. The shower head can be positioned at the opening of the groove, allowing the shower head and top spray's water outlet panels to be configured as a single unit, forming a larger water outlet panel that simultaneously covers the groove. The combined shower head and top spray create a combined water outlet pattern, integrating a shower device with a large water outlet area. It also includes a filter element 30, which is detachably positioned within the groove for easy filter replacement. The shower head is positioned at the opening of the groove after the filter element is positioned there. The filter element can be concealed by the shower head, making it invisible; the overhead shower has an inlet 22 that connects to the water inlet of the filter element and can connect to a 7-shaped bend in the wall. The overhead shower also has a water path switching component 40. The inlet 41 of the water path switching component is connected to the water outlet of the filter element. The first outlet of the water path switching component is connected to the water outlet panel of the overhead shower, and the second outlet of the water path switching component is connected to the water outlet panel of the shower head. The water path between the first outlet of the water path switching component and the overhead shower can be designed inside the overhead shower, while the second outlet of the water path switching component can be connected to the shower head via a hose.

[0030] Preferably, the filter element includes a housing on which filter media can be disposed, the filter media being one type or a combination of multiple types. A guide post 31 is provided on the outer periphery of the housing, and a guide groove 50 is provided on the inner peripheral wall of the groove. The guide post is configured to move within the guide groove to realize the installation or removal of the filter element from the groove. A spring 60 is also disposed in the groove to push the housing out of the groove. The spring is disposed between the groove and the housing. During removal, the spring can hold the filter element out of the groove.

[0031] Specifically, the guide groove includes at least two interconnected sliding grooves, which are M-shaped and apply axial force to the filter element. The guide post moves unidirectionally within the guide groove. The two ends of the sliding groove are configured as openings 56 for the guide post to enter or exit the sliding groove. A fixed area 51 is configured at the corner below the middle of the sliding groove. When the guide post is configured in the fixed area, the filter element is fixed in the groove under the action of a spring. A pair of transition areas 52 are configured at the upper corner of the sliding groove between the fixed area and the opening. The guide post in the transition area can move towards the fixed area and the opening under the action of a spring to realize the installation or removal of the filter element relative to the top spray.

[0032] During installation, the filter element is introduced through the opening at one end of the chute and moved upwards to the first transition zone. At this point, the force is released, and under the action of the spring, the filter element is pushed downwards, causing the guide post to fall into the fixed zone, thus completing the installation of the filter element and maintaining this state. During disassembly, an upward force is applied to the filter element, causing the guide post to move upwards from the fixed zone to another transition zone. Then, the force is released, and under the action of the spring, the filter element is pushed downwards, causing the guide post to move to the opening, thus completing the disassembly of the filter element. It should be noted that during the installation and disassembly process, the filter element undergoes axial (upward) movement and rotation.

[0033] To allow the filter element to be inserted into the groove from any position for installation, guide ramps 53 are provided on both sides below the opening. The two guide ramps form a conical angle. When the filter element is installed or removed from the groove, the guide post can be configured to cooperate with the guide ramp so that the guide post can be guided into the opening. This eliminates the need for manual alignment of the guide post and the opening, simplifying and reducing the work required for filter element installation.

[0034] Meanwhile, the slide groove is also provided with a first guide surface 54. When the guide post slides into the slide groove from the opening, the guide post can slide to the transition area via the first guide surface. The slide groove is also provided with a second guide surface 55. When the filter element is pressed, the guide post can slide from the fixed area to another transition area via the second guide surface, so that the guide post can move in one direction within the slide groove.

[0035] To ensure that the spring force is evenly distributed on the filter element, a stepped surface 23 is provided around the groove. A tray 70 is also placed inside the groove, and the outer edge of the tray can abut against the stepped surface to prevent the tray from being pushed out of the groove. The spring is positioned between the tray and the bottom of the groove. When the filter element is installed in the groove, the water inlet end of the filter element abuts against the lower end face of the tray and pushes and compresses the spring. The tray and the filter element achieve end-face contact, which makes the force exerted by both parties more even.

[0036] In one embodiment, the top spray located on the periphery of the groove is provided with an inner ring 24 and an outer ring 25. A water passage 26 is formed between the outer ring and the inner ring. The outer ring and the inner ring may have overlapping portions in the vertical direction. The water inlet end of the water passage is configured to connect to the water outlet end of the filter element, and the water outlet end of the water passage is configured to connect to the water inlet end of the water path switching component. The housing is provided with an inner shell 32 and an outer shell 33 that can be distributed vertically. The inner shell and the outer shell can be disassembled and fitted together. The main component of the filter element is the inner shell with filter media. The outer shell mainly realizes the trajectory configuration of movement. Moreover, the outer shell can be separately removed into the groove, so that the couple's shower head can also output water without filtration. A flow channel 34 for purified water to flow is formed between the inner shell and the outer shell. The water outlet end of the flow channel can be kept in communication with the water inlet end of the water passage.

[0037] To prevent water leakage, a first sealing ring 81 is provided between the inner shell and the inner ring, and a second sealing ring 82 is provided between the outer shell and the outer ring. Of course, other sealing elements can also be provided at other water-passing connection points, which will not be described in detail here.

[0038] The filter element can be configured such that the filter media can be disposed inside the inner shell to form the core component of the filter element, the inner shell can be inserted into the inner periphery of the outer shell, the outer shell has an opening facing upward for the inner shell to be installed, and the guide post is disposed on the outer peripheral wall of the outer shell.

[0039] This utility model designs a couple's shower head with a built-in filter component. The couple's shower head consists of at least two water outlet devices, a filter element, and a water path switching component. The water path switching component can be a three-way valve or other existing water path switching structure. By using a small number of simple parts, a hidden, removable built-in filter element structure can be achieved in the couple's shower head. Filter element removal is extremely simple, and subsequent removal of the filter element (filter media) does not affect the normal use of the couple's shower head. Simultaneously, the filter element can filter both water outlet devices, as well as allow individual and combined water output from the water outlet devices. The implementation scheme is as follows: 1. The filter element is installed inside the couple's shower head, and water flows in through the inlet. After filtration, the water flows through the water path switching component, which the user can manually switch between (shower head only, shower head + overhead spray simultaneously, overhead spray only); 2. When the filter needs to be replaced or removed, simply remove the shower head and then remove the filter to complete the replacement. Repeat the above operation to complete the installation of the filter and reset of the shower head. During this process, simply apply upward pressure to the filter (bottom of the outer casing); After the filter is removed, whether the filter is installed or not does not affect the normal switching operation of the water path switching component. As long as the outer casing is put back into the groove, that is, even without the inner casing containing the filter media installed, the three water path modes can still be switched normally.

[0040] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
