[0033] Please see Figure 1 This utility model embodiment provides a toilet with a foam sprayer, including a toilet body 100 and a foam sprayer 200. The toilet body 100 contains a bowl 110, and a seat ring 120 is rotatably connected to the top of the toilet body 100. The foam sprayer 200 is installed inside the toilet body 100 and is used to spray foam water onto the inner wall of the bowl 110 to pre-wet the inner wall of the bowl 110.

[0034] In this embodiment, the upper surface of the seat ring 120 is the seating surface 121 that comes into contact with the user. A seating sensor 130 is disposed on the seating surface 121. The seating sensor 130, such as a weight sensor, is used to sense whether the user is sitting on the toilet. The seating sensor 130 may be installed on the left or right side of the seat ring 120, for example. When the user sits down, the seating sensor 130 receives a seating signal. When the user leaves the seat after use, the seating sensor 130 receives an leaving signal.

[0035] Please see Figure 2 The foam ejector 200 is installed inside the toilet body 100. It includes a foam connecting pipe 210, a foam nozzle 220, and a spray control 230. The spray control 230 is connected to the foam connecting pipe 210 to supply foam water to the foam connecting pipe 210. The foam nozzle 220 is connected to the water outlet of the foam connecting pipe 210. The spray end of the foam nozzle 220 faces the inner wall of the toilet bowl 110 and sprays the foam water in a projectile manner.

[0036] Please see Figures 3-6Furthermore, in one embodiment, the spray control unit 230 may include a foaming device and a control device, with the foam connecting pipe 210 connected to the foaming device. The foaming device generates foam water, which is then introduced into the foam connecting pipe 210. The specific structure of the foaming device can refer to existing structures; for example, it may include an air pump and a foaming chamber, with one or more foaming filters inside the foaming chamber. Clean water and cleaning fluid enter the foaming chamber through pipes, and the air pump injects air into the foaming chamber, thereby impacting the liquid inside to form foam water. The control device may include a solenoid valve controller, integrated circuitry, etc., to control the flow of liquid and the opening and closing of the foaming device, thereby achieving on / off control of the foam sprayer 200.

[0037] It is understood that in other embodiments, the foaming device may also be of other structures, as long as it can produce foamy water.

[0038] Furthermore, in one embodiment, the seat sensor 130 is electrically connected to the spray control unit 230 to control the opening and closing of the foam sprayer 230. Specifically, when the seat sensor 130 receives a seat signal, it sends a signal to the foam sprayer 230 to activate the foam sprayer 230 and spray foam water into the toilet bowl.

[0039] Furthermore, in one embodiment, a mounting base 140 is provided above the toilet bowl 110, and a mounting hole 141 is provided on the mounting base 140. One end of the foam nozzle 220 passes through the mounting hole 141 and is connected and fixed to the mounting base 140.

[0040] Furthermore, referring to the figure, in one embodiment, the foam nozzle 220 is detachably connected to the mounting base 140 for easy installation and maintenance. Specifically, the foam nozzle 220 includes a spray end 221 and an interface end 222. The spray end 221 and the interface end 222 are integrally formed and have a generally T-shaped tube structure. The radial length of the spray end 221 is greater than the diameter of the mounting hole 141. The interface end 222 passes through the mounting hole 141, so that the spray end abuts against the front side of the mounting base 140 (the side facing the inner cavity of the toilet bowl), and the interface end 222 is detachably connected to the mounting base 140 by fasteners 223, thereby realizing the connection and fixation between the foam nozzle 220 and the mounting base 140.

[0041] In one embodiment, a seal 225 is provided at the connection between the ejector end 221 and the mounting base 140. The seal 225 is, for example, a sealing gasket. The sealing gasket is fitted at the connection between the ejector end 221 and the interface end 222, and the outer wall of the sealing gasket has a stepped surface, thereby forming a better sealing effect.

[0042] In one embodiment, the fastener 223 is locked into the outer surface of the mounting base 140. Specifically, the side wall of the interface end 222 is provided with external threads, and the fastener 223 is configured as a nut, which locks the interface end 222 onto the mounting base 140. Furthermore, a washer 224 is provided between the fastener 223 and the mounting base 140 to further improve the stability of the connection.

[0043] It should be noted that the foam nozzle 220 and the mounting base 140 can also be connected and fixed in other ways, such as by welding, or by setting a snap-fit ​​assembly to achieve a detachable connection with the mounting base 140.

[0044] Furthermore, in one embodiment, the foam connecting pipe 210 and the interface end 222 of the foam sprayer head 220 are detachably connected via an outer sleeve 226. Specifically, the outlet end of the foam connecting pipe 210 is provided with a T-shaped connector 211, and the outer sleeve 226 is rotatably fitted over the connector 211. The end of the outer sleeve 226 near the foam nozzle 220 is provided with an internal thread, and the outer sleeve 226 and the interface end 222 of the foam nozzle 220 are threaded together, thereby locking and fixing the interface end 222 and the foam connecting pipe 210.

[0045] Furthermore, in one embodiment, the spray end 221 of the foam nozzle 220 has an end face 227, on which a plurality of spray holes 228 are formed, through which foam water is sprayed into the inner cavity of the toilet bowl 110. Specifically, the end face 227 is arc-shaped and protrudes towards the inner cavity of the toilet bowl 110. The plurality of spray holes 228 are linearly arranged on the central axis of the end face 227, and the spray holes 228 are funnel-shaped, narrowing along the spray direction. With the above configuration, a jet of water can be generated in a radial pattern, and a large-angle spray range can be formed to quickly wet the inner wall of the toilet bowl 110.

[0046] It should be noted that in other embodiments, the multiple injection holes 228 may also be arranged in an array, and this disclosure does not impose specific limitations.

[0047] Please see Figure 2 and Figure 7In one embodiment, the toilet body 100 is further provided with a flushing assembly 300. The flushing nozzle 310 of the flushing assembly 300 is located at the end opposite to the foam nozzle 220. The flushing nozzle 310 provides flushing water to the inner wall of the toilet bowl 110, and the flushing water vortexes to flush the inner wall of the toilet bowl. The flushing assembly 300 can also be electrically connected to the seat sensor 130 to control the opening and closing of the flushing assembly 300. For example, when the seat sensor 110 receives a seat signal, it controls the flushing assembly 300 to start, spraying a small amount of water onto the inner wall of the toilet bowl 110 for wetting. When the seat sensor 110 receives a seat signal, it controls the flushing assembly 300 to start, spraying a large amount of flushing water onto the inner wall of the toilet bowl 110.

[0048] The working principle of the toilet with a foam ejector provided in this embodiment is as follows:

[0049] When the user sits down, the seating sensor 130 receives the seating signal, and the spray control unit 230 controls the foam sprayer 200 to start, spraying foam water onto the inner wall of the toilet bowl 110 for pre-wetting. The spraying continues for a certain period of time and then stops, for example, spraying continuously for 3 to 10 seconds and then stopping.

[0050] Alternatively, when the user sits down, the seating sensor 130 receives a seating signal, and the flushing assembly 300 is activated. First, a small amount of water is sprayed onto the inner wall of the toilet bowl 110 for wetting. Then, the foam sprayer 200 is activated, spraying foam water for a period of time. In this way, a foam layer is added on top of the initial wetting, more effectively reducing the adhesion of excrement to the inner wall of the toilet bowl and further improving the cleaning effect.

[0051] It should be understood that the various examples described above can be utilized in multiple directions (e.g., tilted, inverted, horizontal, vertical, etc.) and in multiple configurations without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and the invention is not limited to any specific details of these embodiments.

[0052] Of course, upon careful consideration of the above description of the representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and that such changes are within the scope of the principles of this invention. Therefore, the foregoing detailed description should be clearly understood as being given by way of illustration and example only, and the spirit and scope of this invention are defined solely by the appended claims and their equivalents.
