[0042] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further explained in detail by combining with the figures and embodiments.

[0043] Embodiment one

[0044] As Figures 1-4 ​​​As shown in the drawings, the embodiment discloses a water pump, which comprises a pump body 1, a motor 2 and an impeller 3. The pump body 1 comprises a water outlet cover 11, a pump shell 12 and an end cover 13. The water outlet cover 11 and the end cover 13 are respectively installed at two ends of the pump shell 12, and a pump cavity 14 is formed in the pump body 1. The motor 2 is detachably connected in the pump shell 12, or the motor 2 is integrally formed with the pump shell 12.

[0045] The water outlet cover 11 is provided with a water inlet 15, a first water outlet channel 16 and a second water outlet channel 17. The water inlet 15 is arranged at one side of the water outlet cover 11, and the first water outlet channel 16 and the second water outlet channel 17 are arranged on the side wall of the water outlet cover 11. The water inlet 15, the first water outlet channel 16 and the second water outlet channel 17 are all communicated with the pump cavity 14.

[0046] The water inlet 15 of the water outlet cover 11 is provided with a connecting frame 18, and the connecting frame 18 is provided with an assembly hole 181 at the end. The rotor 21 of the motor 2 is fixedly connected with the impeller 3, and the motor shaft 22 is connected with the assembly hole 181 of the connecting frame 18. The cross section of the assembly hole 19 connected with the motor shaft 22 is in D shape, which can prevent the motor shaft 22 from rotating axially in the assembly hole 181. The impeller 3 is arranged in the pump cavity 14, and the impeller 3 comprises a first connecting plate 31, a second connecting plate 32 and a plurality of blades 33 arranged uniformly between the first connecting plate 31 and the second connecting plate 32. Figure 4 As shown in the drawings, the middle part of the first connecting plate 31 is provided with an opening 34, and the end of the opening 34 is provided with an arc-shaped guide surface 35 for guiding water flow. The water flow can enter the impeller 3 through the opening 34 after entering the water inlet 15, and the water flow is guided to the first water outlet channel 16 or the second water outlet channel 17 by the rotation of the impeller 3.

[0047] In combination Figure 6 As shown in the drawings, the motor 2 is a reversible motor, and the motor 2 drives the impeller 3 to rotate in a first direction or a second direction. The first direction is the clockwise direction, and the second direction is the counterclockwise direction. Figure 6 W1, and the second direction is the counterclockwise direction. Figure 7 W2. In other embodiments, the first direction can also be the counterclockwise direction, and the second direction is the clockwise direction.

[0048] The principle of the water outlet is as follows: when the impeller 3 rotates in a direction, the water flow is easy to flow out along the tangent direction, and is not easy to flow out against the tangent direction. The tangent direction along which the opening of the water outlet is defined as: the opening of the water outlet is arranged in the tangent direction parallel to the outer edge of the corresponding pump cavity (along the current rotating direction), or is arranged at a small included angle α with the tangent direction. The tangent direction against which the opening of the water outlet is defined as: the opening of the water outlet is arranged in the tangent direction parallel to the outer edge of the corresponding pump cavity (against the current rotating direction), or is arranged at a small included angle α with the tangent direction. When the opening of the water outlet is arranged in the tangent direction at a large included angle β with the tangent direction parallel to the outer edge of the corresponding pump cavity, the included angle β > α, no matter whether the rotating direction is the first direction or the second direction, the water flow can flow out from the current outlet. The included angle defined in the application is an angle less than 90 degrees, in order to make the corresponding flow meet the requirements, the included angle α ≤ 30°, and the included angle β > 30°; more preferably, the included angle α ≤ 10°, and the included angle β > 45°.

[0049] In combination Figures 8a-8e The setting principle of the first water outlet channel 16 and the second water outlet channel 17 of the utility model is explained by using simple drawings. The first water outlet channel 16 comprises a first water outlet 161, the opening of the first water outlet 161 is arranged in the tangent direction parallel to the outer edge of the corresponding pump cavity, or is arranged at an included angle α with the tangent direction, the included angle α ≤ 30°; and the direction of the first water outlet 161 is along the water flow direction of the impeller 3 rotating in the first direction. In order to meet the design requirement of miniaturization, generally only one first water outlet 161 needs to be arranged in the first water outlet channel 16. In some embodiments, the first water outlet channel 16 is further provided with other water outlets, the flow of the other water outlets is extremely small, and the realization of the effect of the application is not affected. The second water outlet channel 17 is provided with one or more second water outlets 171, so that at least one second water outlet 171 discharges water when the impeller rotates in the first direction or in the second direction, and the second water outlet channel 17 is connected to the outside of the shell. Through such a principle, when the impeller 3 rotates in the first direction, the water flow flows out along the first water outlet 161 and at least one second water outlet 171. When the impeller 3 rotates in the second direction, the water flow basically flows out along the second water outlet 171, and does not flow out from the first water outlet 161, or only a small amount of water flows out from the first water outlet 161. Through such a structure, the water pump of the utility model is suitable for two application scenarios of the closestool: when it is required to enter the drainage mode, the water flow needs to discharge water from the first water outlet channel and the second water outlet channel at the same time; and when it is required to enter the washing, water supplementing and wall moistening mode, the water flow only discharges water from the second water outlet channel, so as to save the water consumption. The water pump of the utility model can also be suitable for other similar application scenarios.

[0050] The two second water outlets 171 of the second water outlet channel 17 are generally arranged in the following several embodiments:

[0051] (1) asFigure 8a In the embodiment, the first water outlet channel 16 is provided with a first water outlet 161, and the second water outlet channel 17 is provided with two second water outlets 171. The first water outlet 161 corresponds to a point P1 on the outer edge of the pump cavity, and the tangent line along P1 is the setting direction of the first water outlet 161. The two second water outlets 171 are respectively a second water outlet A 1711 and a second water outlet B 1712. The opening of the second water outlet A 1711 is arranged at an angle β to the tangent direction of the corresponding outer edge of the pump cavity, and the angle β is greater than 30°. In the figure, the point corresponding to the second water outlet A 1711 on the outer edge of the pump cavity is P2, and a tangent line q2 is drawn along P2. The opening of the second water outlet A 1711 is arranged at an angle β1=52° to the tangent line q2. The opening of the second water outlet B 1712 is parallel to the tangent direction of the corresponding outer edge of the pump cavity, or is arranged at an angle α to the tangent direction, and the angle α is less than or equal to 30°. The direction of the second water outlet B 1712 is along the water flow direction of the impeller 3 rotating in the second direction. In the figure, the point corresponding to the second water outlet B 1712 on the outer edge of the pump cavity is P3, and the tangent line along P3 is the setting direction of the second water outlet B. In other embodiments, as shown in Figure 8b the figure, the first water outlet 161 and the second water outlet B 1712 can also have a slight angle deviation from the tangent direction (the tangent line q1 corresponding to the first water outlet 161, and the tangent line q2 corresponding to the second water outlet B 1712), that is, the control deviation angle α1\α2 is within 30 degrees. When the impeller 3 rotates along the W1 direction, the water flow mainly flows out from the first water outlet 161 and the second water outlet A 1711. Since the second water outlet B 1712 is opposite to the tangent direction of rotation at this time, the water flow is basically not discharged from the second water outlet B 1712. When the impeller 3 rotates along the W2 direction, the water flow flows out from the second water outlet A 1711 and the second water outlet B 1712. Since the first water outlet 161 is opposite to the tangent direction of rotation at this time, the water flow is basically not discharged from the first water outlet 161.

[0052] (2) as Figure 8cAs shown, the second water outlet channel includes a second water outlet B 1712 and a second water outlet C 1713. The opening of the second water outlet B 1712 is directed along a tangent direction of W2 parallel to the corresponding pump cavity outer edge P3, i.e. the direction of the second water outlet B 1712 is along the water flow direction of the impeller rotating in the second direction. The opening of the second water outlet C 1713 is directed along a tangent direction of W1 parallel to the corresponding pump cavity outer edge P2, i.e. the direction of the second water outlet C is along the water flow direction of the impeller rotating in the first direction. When the impeller 3 rotates in the direction of W2, water flows out from the second water outlet B 1712, and since the first water outlet 161 and the second water outlet C 1713 are against the tangent direction of rotation at this time, water basically does not flow out from the first water outlet 161 and the second water outlet C 1713. When the impeller 3 rotates in the direction of W1, water flows out from the first water outlet 161 and the second water outlet C 1713, and since the second water outlet B 1712 is against the tangent direction of rotation at this time, water basically does not flow out from the second water outlet B 1712.

[0053] (3) as shown in Figure 8d As shown, the second water outlet channel includes a second water outlet B 1712 and a second water outlet D 1714. The opening of the second water outlet B 1712 is directed along a tangent direction of W2 parallel to the corresponding pump cavity outer edge P3, i.e. the direction of the second water outlet B 1712 is along the water flow direction of the impeller rotating in the second direction. The opening of the second water outlet D 1714 is directed along a tangent direction of W1 parallel to the corresponding pump cavity outer edge P2 at an angle β3 = 90°. When the impeller 3 rotates in the direction of W2, water flows out from the second water outlet B 1712 and the second water outlet D 1714, and since the first water outlet 161 is against the tangent direction of rotation at this time, water basically does not flow out from the first water outlet 161. When the impeller 3 rotates in the direction of W1, water flows out from the first water outlet 161 and the second water outlet D 1714, and since the second water outlet B 1712 is against the tangent direction of rotation at this time, water basically does not flow out from the second water outlet B 1712.

[0054] As shown in Figure 8eAs shown, in the embodiment, the first water outlet channel 16 is provided with a first water outlet 161, and the second water outlet channel 17 is provided with a second water outlet 171. The corresponding pump cavity outer edge of the first water outlet 161 is point P1, and the tangent line along P1 is the setting direction of the first water outlet 161. The opening direction of the second water outlet 171 is arranged at an angle β with the tangent direction of the corresponding pump cavity outer edge. In the figure, the point of the second water outlet 171 corresponding to the pump cavity outer edge is P3, a tangent line q3 is drawn along P3, and the opening direction of the second water outlet 171 is at an angle β2=60° with the tangent line q2. When the impeller 3 rotates along the W1 direction, the water flow flows out from the first water outlet 161 and the second water outlet 171 at the same time. When the impeller 3 rotates along the W2 direction, the water flow flows out from the second water outlet 171. Since the first water outlet 161 is opposite to the tangent direction of rotation at this time, the water flow basically does not flow out from the first water outlet 161.

[0055] Through the above principle description, combined with Figures 6-7 , in the embodiment of the utility model, the second water outlet channel 17 is arranged as a cylindrical pipe body, the cylindrical pipe body is provided with a pump cavity connecting section 172 and a confluence section 173, the pump cavity connecting section 172 is provided with a through second water outlet A 1711 and a second water outlet B 1712, and the second water outlet A 1711 and the second water outlet B 1712 are arranged in axial parallel. The confluence section 173 has a confluence outlet 1731, the confluence section 173 is integrally formed with the pump cavity connecting section 172, or the confluence section 173 is sealingly assembled to the pump cavity connecting section 172. The confluence outlet 1731 is communicated with the second water outlet A 1711 and the second water outlet B 1712. By arranging the confluence section 173, only one pipeline needs to be connected in specific application, the convenience of connection is improved, and the volume of the water pump is reduced. For example, Figure 6 When the impeller 3 rotates along the W1 direction, the water flow mainly flows out from the first water outlet 161 and the second water outlet A 1711 (the solid line arrow direction in the figure is the water flow direction), since the second water outlet B 1712 is opposite to the tangent direction of rotation at this time, the water flow basically does not flow out from the second water outlet B 1712. Figure 7 When the impeller 3 rotates along the W2 direction, the water flow flows out from the second water outlet A 1711 and the second water outlet B 1712 (the dotted line arrow direction in the figure is the water flow direction), since the first water outlet 161 is opposite to the tangent direction of rotation at this time, the water flow basically does not flow out from the first water outlet 161.

[0056] Combined with Figure 5 , Figure 8aAs shown, in order to make the impeller 3 along the second direction (W2 direction) rotation, the water flow from the first water outlet 161 as far as possible, the inner wall of the pump cavity 14 is also provided with a wedge block 19. The wedge block 19 is provided at the end of the first water outlet 161, the wedge block 19 is inclined to the inner wall of the pump cavity 14, the wedge block 19 front end face protruding from the first water outlet 161 is provided, the rear end surface and the inner wall of the pump cavity 14 is smoothly connected. Through this setting, when rotating along the second direction, the water flow is blocked by the wedge block 19, which can further avoid flowing out from the first water outlet 161, but along the wedge block to cross the first water outlet 161.

Alternatively, the outer pipe 53, the inner pipe 51, and the mounting hole 41 cooperate to confine the connecting fitting to the tank wall. The anti-siphon port 55 is set higher than the working water level of the tank 4. When the position of the toilet's wash opening is higher than the working water level in the tank 4, the anti-siphon port 55 does not need to be provided on the wash pipe 6; that is, only an opening needs to be provided on the drain pipe 5, and no opening needs to be provided on the wash pipe 6. By providing the anti-siphon port 55, water backflow into the tank 4 can be prevented.

[0062] The ends of the drainage pipe 5 and the washing pipe 6 can also be connected to the nozzle 61 to increase the water pressure and adjust the water angle.

[0063] Water tank 4 is equipped with a water supply port and an inlet valve 7. Water is supplied to water tank 4 by connecting to an external water source through the inlet valve 7. Water tank 4 is not equipped with an overflow port 42. When the inlet valve 7 malfunctions and the water tank 4 is too full, water will flow out from the overflow port 42.

[0064] Example 3

[0065] like Figures 13-15 As shown, this embodiment discloses a toilet, including a toilet body 8, which includes a toilet seat cavity 81 and an installation cavity 82. The water tank 4 of the flushing system is disposed in the installation cavity 82. The wall surface of the toilet seat cavity 81 is provided with a plurality of washing holes 811, and the bottom of the toilet seat cavity 81 is provided with a drain outlet 812. The ends of the drain pipe 5 and the washing pipe 6 are also connected to nozzles 61. The nozzles 61 of the drain pipe 5 are installed at the drain outlet 812, and the nozzles 61 of the washing pipe 6 are installed at the washing holes 811, so that the water flow of the drain pipe 5 is connected to the drain outlet 812, and the water flow of the washing pipe 6 is connected to the washing holes 811.

[0066] When motor 2 controls impeller 3 to rotate in the W1 direction, water flows out from both the first water outlet channel 16 and the second water outlet channel 17, washing the wall above the toilet chamber 81 and simultaneously flushing the drain outlet 812. Water splashes and dirt on the wall during flushing are also cleaned by the water flowing from the washing hole 811. When motor 2 controls impeller 3 to rotate in the W2 direction, water flows only from the second water outlet channel 17, washing, moisturizing, or replenishing the wall above the toilet chamber 81. In this mode, the first water outlet channel 16 is not flushed, saving water and offering flexible usage scenarios.
