Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to a pre-wetting device and a toilet. Background Technology

[0002] Pre-wetting of ceramics involves spraying water onto the sidewalls of the ceramic surface before use to enhance its stain resistance. This is especially important for bathroom products like toilets, as pre-wetting the ceramic part improves its stain resistance and prevents dirt from adhering to the inner ceramic wall, making cleaning easier. Currently, toilets on the market are divided into smart and non-smart types. Smart toilets generally have a pre-wetting function, while non-smart toilets (also known as ordinary or conventional toilets) typically do not. For non-smart toilets, pre-wetting can be achieved by pressing a flush button, but this has the following drawbacks: a larger flush volume, which is not water-saving; and the tank needs to be refilled during use, which generates noise and affects the user experience.

[0029] Please see Figures 1-6 As shown, this utility model discloses a pre-wetting device for a toilet. The toilet includes a toilet seat 8 and a water tank 9 located at the rear top of the toilet seat 8. The toilet seat 8 has a brush ring water passage 81, and the water tank 9 has a water inlet valve 7. The pre-wetting device of this utility model includes a pre-wetting pipe 1 and a control valve. The inlet end of the control valve is connected to the inlet channel of the water inlet valve 7, and the outlet end of the control valve is connected to one end of the pre-wetting pipe 1. The other end of the pre-wetting pipe 1 is connected to the brush ring water passage 81 of the toilet seat 8. Therefore, this utility model enables ordinary toilets to achieve a pre-wetting function, and its simple structure does not affect the normal flushing function of the water tank 9, greatly improving the user experience.

[0030] As a preferred embodiment, the pre-wetting device of this invention also includes a foaming module 3, which can also be called a foam generator or foam generating device. It is positioned between the water outlet of the control valve and one end of the pre-wetting pipe 1. Water from the control valve enters the foaming module 3 and mixes with the foaming agent stored within it, generating foam. This foam is then output through the pre-wetting pipe 1. Therefore, this invention can use foam to lubricate the ceramic inner wall, significantly improving the pre-wetting effect compared to directly using water, thereby enhancing the toilet's stain resistance. Furthermore, the foam can also act as an odor barrier, further improving the user experience.

[0031] The pre-wetting device of this invention also includes a water pipe 4, one end of which is connected to the outlet of the control valve, and the other end of which is connected to the pre-wetting pipe 1. Therefore, this invention can use the action of water flow to carry foam to the toilet bowl surface, so that the foam can be quickly sprayed onto the parts of the toilet bowl surface that need to be pre-wetted in a short time.

[0032] Furthermore, the pre-wetting device of this utility model also includes a three-way pipe 5. The first end of the three-way pipe 5 is connected to the water inlet of the control valve, the second end of the three-way pipe 5 is connected to the water inlet of the foaming module 3, and the third end of the three-way pipe 5 is connected to one end of the water pipe 4. The three-way pipe 5 is integrated into the foaming module 3, which makes the overall modularity high and facilitates transportation and installation.

[0033] The foaming module 3 is provided with a foaming channel 31 and a water inlet 32 ​​connected to the foaming channel 31. The other end of the water pipe 4 is connected to the water inlet 32. The foaming end of the foaming channel 31 of the foaming module 3 is connected to one end of the pre-wetting pipe 1, which is a flexible hose. The other end of the pre-wetting pipe 1 is connected to a foaming nozzle 6, which is connected to the side wall where the brush ring pipe 81 is located. Figure 5 As shown.

[0034] The pre-wetting device of this invention also includes a pre-wetting button 20, which is installed on the cover 91 of the water tank 9. When the pre-wetting button 20 is pressed, it triggers the control valve located inside the water tank 9 to open. Preferably, the control valve is a pulse-type solenoid valve 3, which is electrically connected to a control board (not shown in the figure). The control board has a self-resetting microswitch. When the pre-wetting button 20 is pressed, it triggers the microswitch, causing the control board to control the solenoid valve 3 to open. This invention also includes a battery (not shown in the figure) that powers the solenoid valve 3 and the control board. Both the control board and the solenoid valve 3 are located inside the water tank 9 and are above the highest water level in the tank 9. In other embodiments, the control valve is a mechanical valve.

[0035] Please see Figures 1-6 As shown, a toilet of the present invention includes a toilet seat 8 and a water tank 9 located at the rear top of the toilet seat 8. The toilet seat 8 is provided with a brush ring water passage 81. The water tank 9 is provided with an inlet valve 7 and a drain valve 10. The water tank 9 and the toilet seat 8 are integrally formed, but are not limited thereto. It also includes a pre-wetting device as described in the present invention.

[0036] In this embodiment, the side wall of the water inlet valve 7 is provided with a water inlet 71 that connects to its water inlet channel. The water inlet 71 is connected to the water inlet of the control valve (i.e., the solenoid valve 3) by a water pipe 72.

[0037] In this embodiment, the present invention further includes a filling port for adding foaming agent to the foaming module 3. The filling port is located on the cover 91 of the water tank 9 and communicates with the liquid storage chamber of the foaming module 3. A decorative cover 30 for opening and closing the filling port is provided on the cover 91 of the water tank 9. In other embodiments, the filling port is located on the foaming module 3.

[0038] In this embodiment, the bottom wall of the water tank 9 is provided with an installation port 92 corresponding to the foaming module 3. The foaming module 3 is sealed and connected to the installation port 92, and the pre-wetting pipeline 1 is located below the water tank 9.

[0039] This utility model discloses a pre-wetting device and toilet. When the pre-wetting function needs to be activated, pressing the pre-wetting button 20 opens the solenoid valve 3. Tap water then flows through the inlet of the inlet valve 7 and the water pipe to the solenoid valve 3, and is divided into two streams through the three-way pipe 5. One stream enters the foaming module 3 for foaming (the foaming module 3 uses the Venturi effect to mix the foaming agent with the water), and the resulting foam enters the foam outlet channel 31 of the foaming module 3. The other stream enters the foam outlet channel 31 through the pressurized water path and the inlet 32, merges with the foam, and enters the brush ring water path 81 through the pre-wetting pipe 1 and the foaming nozzle, finally spraying onto the pre-wetting area 82 of the toilet bowl. Figures 4-6 As shown in the diagram, the arrows indicate the direction of water flow and foam. When the pre-wetting button 20 is released, it automatically rebounds, the microswitch on the control panel automatically resets, and the solenoid valve 3 closes.

[0040] This invention relates to a pre-wetting device and toilet, enabling ordinary toilets to perform a pre-wetting function. Specifically, this invention uses foam to moisten the toilet bowl surface, preventing stool from sticking, improving cleaning efficiency, and providing splash prevention and odor control. Furthermore, this invention allows control over the opening duration of the solenoid valve 3 via a control panel, thereby controlling water usage. This means that during pre-wetting, only a specific area of ​​the toilet bowl surface needs to be sprayed, rather than the entire surface, thus saving water.

[0041] The pre-wetting device and toilet of this utility model are identical to or can be implemented using existing technologies in parts not covered herein (such as the structure and working principle of the foaming module 3).

[0042] The above embodiments are only used to further illustrate a pre-wetting device and toilet of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
