[0032] See also Figure 1-Figure 8As shown, a toilet self-cleaning device of the utility model includes a base 1, a spray pipe 10, and a driving mechanism. The spray pipe 10 is connected to the base 1 so as to be rotatable at least around its axis and is driven to rotate by the driving mechanism. The water outlet end of the spray pipe 10 is eccentrically provided with at least one water outlet 101 for outputting water to clean or pre-moisten the pot surface of the toilet. There is a first angle α between the water outlet direction of the water outlet 101 of the spray pipe 10 and the end face 44 of the water outlet end of the spray pipe 10, and the projection (vertical projection) of the water outlet direction of the water outlet 101 on the end face 44 of the water outlet end of the spray pipe 10 forms a first direction a, and the radial direction of the water outlet 101 on the end face 44 of the water outlet end of the spray pipe 10 forms a second direction b, and there is a second angle β between the first direction a and the second direction b, as shown in FIG. Figure 6 The first angle α is an acute angle, and the second angle β is less than 90°, that is, the second angle β is also an acute angle. The water outlet end of the spray pipe 10 refers to the end of the spray pipe 10 for outputting water flow.

[0033] The number of the water outlets 101 is multiple, and the multiple water outlets 101 are arranged at intervals along the circumferential direction of the water outlet end of the injection pipe 10. Specifically, the number of the water outlets 101 is two, and the two water outlets 101 are in the same radial direction on the end surface 44 of the water outlet end of the injection pipe 10. In other embodiments, the number of the water outlet 101 is one.

[0034] Preferably, the cross-section of the water outlet 101 is in the shape of an elongated strip, so that the water outlet 101 outputs a sheet-like water flow, and the length direction of the cross-section of the water outlet 101 is located in the radial direction (i.e., the second direction b) where the end face 44 of the water outlet 101 at the water outlet end of the injection pipe 10 is located, and the two opposite wall surfaces of the water outlet 101 in its width direction are respectively inclined relative to the end face 44 of the water outlet end of the injection pipe 10, so that the water outlet direction of the water outlet 101 forms the first angle α and the second angle β.

[0035] In this embodiment, the spray pipe 10 can also be connected to the base 1 in a slidable manner along the axial direction of the spray pipe 10 relative to the base 1, and driven to slide by the driving mechanism, so that the spray pipe 10 has a telescopic function.

[0036] In this embodiment, the spray pipe 10 includes a conduit 3 and a nozzle 4. The conduit 3 is provided with a water flow channel 33. The conduit 3 is connected to the base 1 in a matching manner between the spray pipe 10 and the base 1, that is, the conduit 3 can rotate around its axial direction and can be slidably connected to the base 1 along its axial direction. The nozzle 4 is connected to one end of the conduit 3, and a seal is provided between the two. The nozzle 4 and one end of the conduit 3 cooperate with each other to form a water outlet 101, and the water outlet 101 is connected to the water flow channel 33. Specifically, the number of the water flow channels 33 is also two, and the two water flow channels 33 are connected to the two water outlets 101 one by one. In other embodiments, the nozzle 4 is provided with the water outlet 101.

[0037] Specifically, Figure 3-Figure 5 As shown, a first cut surface 31 is provided at one end of the conduit 3, and a second cut surface 41 is provided at the nozzle 4. The first cut surface 31 and the second cut surface 41 are inclined relative to the end surface 44 of the water outlet end of the spray pipe 10, respectively, and the first cut surface 31 and the second cut surface 41 are opposite to each other and are clearance-matched, and form two opposite walls of the water outlet 101 in its width direction. A first groove 32 extending along the water outlet direction of the water outlet 101 is provided in the middle position of the first cut surface 31, and a second groove 42 extending along the water outlet direction of the water outlet 101 is provided in the middle position of the second cut surface 41. The first groove 32 and the second groove 42 are arranged opposite to each other. The arrangement of the first groove 32 and the second groove 42 can increase the cross-sectional area of ​​the water outlet 101, thereby increasing the water outlet of the water outlet 101, and further improving the cleaning effect on the toilet pot surface.

[0038] In this embodiment, the nozzle 4 is detachably connected to the conduit 3. Specifically, the nozzle 4 is provided with a plurality of connecting columns 43 extending along the axial direction thereof on the side facing the conduit 3, each connecting column 43 is a hollow structure and provided with an internal thread, and one end of the conduit 3 is provided with a mounting hole 34 corresponding to each connecting column 43; the nozzle 4 is connected to one end of the conduit 3 by a plurality of screws 6, and the screw rod of each screw 6 passes through the mounting hole 34 and is threadedly connected with the internal thread of the connecting column 43. In other embodiments, the nozzle 4 is snap-connected to the conduit 3.

[0039] The utility model provides a toilet self-cleaning device. When working, water enters the water flow channel 33 of the conduit 3 and flows to the water outlet 101. Finally, water is output from the water outlet 101 at a state corresponding to the first angle α and the second angle β. Figure 7 , Figure 8 As shown, the arrows in the figure indicate the direction of water flow. Figure 8 middle, Fig. 9 The object indicated by the middle number c illustrates the water flow outputted from the water outlet 101 . It is a simple illustration and focuses on reflecting the water outlet direction rather than illustrating the sheet-like water flow.

[0040] When the utility model is applied to a toilet, the water flow c outputted from the water outlet 101 can be sprayed onto the toilet pot surface at an angle relative to the toilet pot surface, rather than vertically impacting the toilet pot surface. Therefore, the toilet self-cleaning device of the utility model can better clean the dirt on the toilet pot surface and greatly reduce the occurrence of water splashing.

[0041] See also Figure 1-Figure 10 As shown, a toilet of the utility model includes a toilet seat 7, an intelligent toilet cover, and also includes the toilet self-cleaning device of the utility model as described above, wherein the base 1 of the toilet self-cleaning device is specifically installed on the base of the intelligent toilet cover 8, and the spray pipe 10 is located at the rear top of the pot surface 71 of the toilet seat 7, the water outlet end of the spray pipe 10 faces downward, and the water flow output by the water outlet 101 of the spray pipe 10 is sprayed obliquely onto the pot surface 71 of the toilet seat 7.

[0042] When the toilet self-cleaning device is working, the water flow c output by the spray pipe 10 is sprayed obliquely onto the pot surface 71 of the toilet seat 7, such as Fig.10 As shown in FIG. 1 , the impact force of the water flow c obliquely sprayed onto the pot surface 71 can be decomposed into a component force Fy perpendicular to the pot surface 71 and a component force Fx extending along the pot surface 71. The water flow c obliquely sprayed onto the pot surface 71 is decomposed into water flow c1 and water flow c2 after impacting the pot surface 71, as shown in FIG. Fig.10 As shown, at this time, the water flows along the two streams c1 and c2. If V0, V1 and V2 are used to represent the speeds of streams c, c1 and c2 respectively, and θ is used to represent the angle between stream c and the pot surface 71, then V1 = (1 + cosθ) V0 / 2

[0043] V2=(1-cosθ)V0 / 2

[0044] Substituting θ equal to 0 into the above formula, we can get V1 = V0, V2 = 0

[0045] Substituting θ equal to 90° into the above formula, we can get V1 = V0 / 2, V2 = V0 / 2

[0046] Therefore, the present invention can conclude that the spray pipe 10 sprays the water flow c slightly at an angle, which can better clean the dirt on the pot surface 71 and the water flow is less likely to splash.

[0047] The utility model provides a toilet self-cleaning device and a toilet, and the uninvolved parts (such as the structure of the driving mechanism and its working principle, etc.) are the same as those in the prior art or can be implemented by using the prior art.
