It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0039] like Figures 1 to 3 As shown, a water inlet filtration device includes:

[0040] The main body 10 is provided with a water passage cavity 11, and a water inlet end 12 and a water outlet end 13 respectively connected to the water passage cavity 11;

[0041] The control valve 20 includes a water supply channel connected to the water outlet 13. The control valve 20 can control the opening and closing of the water supply channel. The control valve 20 is a solenoid valve, which is used to supply water to the toilet's cleaning water circuit, which includes a bidet water circuit, a feminine wash water circuit, etc.

[0042] The filter assembly 30 is detachably installed in the water passage chamber 11. The filter assembly 30 includes a filter element 31. The inlet 32 ​​of the filter element 31 is connected to the water inlet end 12. The gap between the filter element 31 and the inner wall of the water passage chamber 11 forms a purified water channel 14 connected to the water outlet end 13. The outlet 33 of the filter element 31 is connected to the purified water channel 14. The filter element 31 is filled with filter media and / or scale inhibitor. In this embodiment, the filter element 31 is filled with filter media and scale inhibitor, which can both filter impurities in the water and inhibit scale to improve water quality.

[0043] In this embodiment, the water inlet 12 is provided with a water valve 40, the filter assembly 30 is installed in the water passage chamber 11, the filter assembly 30 presses against the water valve 40 to open the water inlet 12, and after the filter assembly 30 is removed, the water valve 40 closes the water inlet 12; the bottom of the filter assembly 30 is provided with a pressure rod 34 that cooperates with the water valve 40 to press against it.

[0044] Specifically, the water valve 40 is a reverse-installed check valve. After the filter assembly 30 is installed, the pressure rod 34 pushes open the check valve to enable automatic water intake after the filter assembly 30 is installed. Conversely, after the filter assembly 30 is removed, the check valve closes to automatically cut off the water circuit after the filter assembly 30 is removed.

[0045] In this embodiment, the water passage cavity 11 is provided with an installation port 15, and the filter assembly 30 is installed into the water passage cavity 11 through the installation port 15. A sealing ring is provided between the filter assembly 30 and the installation port 15 for a sealing fit.

[0046] In this embodiment, the filter assembly 30 is provided with an external thread, the mounting port 15 is provided with an internal thread, and the filter assembly 30 is threadedly connected to the water passage cavity 11.

[0047] In other embodiments, the filter assembly 30 is provided with a snap-fit ​​part, and the mounting port 15 is provided with a limiting part, and the filter assembly 30 is snap-fitted into the water passage cavity 11.

[0048] In this embodiment, the filtration assembly 30 further includes a filter 35, which is installed upstream of the filter element 31. Water from the inlet 12 enters the filter element 31 after being filtered by the filter 35, thus achieving multi-stage filtration and good filtration effect.

[0049] In this embodiment, the filter 35 includes a filter frame, the bottom of which is provided with an inlet 36 connected to the water inlet 12. The filter frame is also provided with a filter screen 37 arranged longitudinally. The filter screen 37 is located between the inlet 36 and the inlet 32 ​​of the filter element 31. Water from the water inlet 12 enters the filter frame through the inlet 36 and flows to the inlet 32 ​​of the filter element 31 after being filtered by the filter screen 37. The filter 35 and the filter element 31 are engaged and matched.

[0050] The specific working process of this embodiment is as follows:

[0051] Water from the water supply pipe enters the main body 10 through the braided tube. Water from the inlet 12 of the main body 10 enters the filter frame through the inlet 36 of the filter 35 after passing through the water valve 40. After primary filtration through the filter screen 37, the water flows to the inlet 32 ​​of the filter element 31. After secondary filtration through the filter element 31 and contact with the internal scale inhibitor, the water exits from the outlet 33 of the filter element 31. Then, it flows through the clean water channel 14 to the outlet 13 and enters the solenoid valve. When the solenoid valve is opened, water is supplied to the toilet cleaning water circuit.

[0052] When the filter assembly 30 is assembled, it is connected to the main body 10 by rotating the thread. During the rotation, as the thread is turned in, the pressure rod 34 of the filter assembly 30 pushes open the water valve 40, and the water valve 40 opens the water inlet. Conversely, when the filter assembly 30 is turned out, the water valve 40 closes, so that the water valve 40 automatically cuts off the water circuit after the filter assembly 30 is removed.

[0053] like Figure 4 and Figure 5 As shown, this utility model also proposes an intelligent toilet, including a base 60 installed on a toilet seat 50, and a water inlet filter device as described above. The filter device is installed inside the base 60. The base 60 includes a fixed seat and a rear shell 61. The rear shell 61 has a clearance hole 62, and the filter device can be removed from the clearance hole 62.
