DETAILED DESCRIPTION

[0048] In order to make the purpose, technical scheme and advantages of the utility model more clearly understood, the utility model is further described in detail below in combination with the drawings and embodiments.

[0049] Embodiment one

[0050] As Figures 1 to 15 shown, the embodiment discloses an integrated water piece, which comprises a shell 91, a drainage mechanism 92, a drainage base 93 and a water pump 1. The water pump 1 and the drainage mechanism 92 are installed in the inner cavity of the shell 91. The drainage base 93 is installed below the shell 91.

Through this arrangement, the filter cover 911 can realize the water flow to meet the needs of the water source entering the water pump 1, and by being arranged in the form of the filter cover 911, it can also block the impurities in the water from entering the shell 91 and blocking the water inlet 15 of the water pump 1.

[0052] The drainage mechanism 92 is a mechanism that can realize the opening and plugging of the drainage base to realize the opening and closing control of water flow. The commonly used drainage valve on the market can also be used, and the structures disclosed in the public numbers CN115262718A, CN103074926A, CN219909210U, etc. can also be used.

[0053] Combining Figures 7 to 9 As shown in the figure, the water pump 1 includes a pump body 10, a motor 2 and an impeller 3. The pump body 1 includes 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 both ends of the pump shell 12, and a pump cavity 14 is formed inside the pump body 1. The motor 2 is detachably connected in the pump shell 12, or the shell of the motor 2 is integrally formed with the pump shell 12.

[0054] The water outlet cover 11 is provided with a water inlet 15, a first water outlet channel 16, a second water outlet channel 17 and a third water outlet channel 18. The water inlet 15 is arranged on one side of the water outlet cover 11, and the first water outlet channel 16, the second water outlet channel 17 and the third water outlet channel 18 are arranged on the side wall of the water outlet cover 11. The water inlet 15, the first water outlet channel 16, the second water outlet channel 17 and the third water outlet channel 18 are all connected to the pump cavity 14.

[0055] Combining Figure 10 As shown in the figure, the water inlet 15 of the water outlet cover 11 is provided with a connecting frame 111, and the end of the connecting frame 111 is provided with an assembly hole 112. 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 112 of the connecting frame 111. The cross section of the assembly hole 112 and the motor shaft 22 is D-shaped, which can prevent the motor shaft 22 from rotating axially in the assembly hole 112. The impeller 3 is built in the pump cavity 14, and the impeller 3 includes a first connecting plate 31, a second connecting plate 32 and a plurality of blades 33 uniformly arranged between the first connecting plate 31 and the second connecting plate 32. Combining Figure 9 As shown in the figure, the middle part of the first connecting plate 31 is provided with an opening 34, and the diameter of the opening 34 is greater than that of the water inlet 15. The end of the opening 34 is provided with an arc guide surface 35 for guiding water flow, which facilitates the water flow from the water inlet 15 to enter the impeller 3 through the opening 34, and the impeller 3 rotates to guide the water flow to the first water outlet channel 16, the second water outlet channel 17 and the third water outlet channel 18.

[0056] Combination Figure 12 As shown, motor 2 is a reversible motor, and motor 2 drives impeller 3 to rotate in either a first direction or a second direction. The first direction is clockwise, as shown below. Figure 12 In the middle W1, the second direction is counterclockwise, such as... Figure 13 W2. In other embodiments, the first direction may also be counterclockwise, and the second direction may be clockwise.

[0057] The first water outlet channel 16 is connected to the drainage mechanism 92. When water flows out of the first water outlet channel 16, the piston inside the drainage mechanism 92 of the water pump 1 moves upward under the action of water pressure, thereby opening the water-sealing rubber 921 below the drainage mechanism 92, that is, opening the water inlet of the drainage base 93, so that water can flow out from the drainage base 93. The second water outlet channel 17 is connected to the outside of the housing 91 to connect with the external washing pipe 6. The third water outlet channel 18 is connected to the flushing aid pipe 94, and the other end of the flushing aid pipe 94 is connected to the outlet of the drainage base 93.

[0058] Combination Figure 6 As shown, the flushing aid pipe 94 includes a support pipe 941, an inverted U-shaped pipe 942, and a flushing aid pipe 943. One end of the support pipe 941 is detachably connected to the third outlet 181, and the other end is connected to the inverted U-shaped pipe 942. The other end of the inverted U-shaped pipe 942 is connected to one end of the flushing aid pipe 943, and the other end of the flushing aid pipe 943 is connected to the outlet of the drain base 93. The inverted U-shaped pipe 942 is provided with an anti-siphon hole 944, which is positioned higher than the working water level in the water tank to reduce the influence of negative pressure in the pipe and prevent siphoning. The flushing aid pipe 943 is inserted into the drain base 93 and communicates with the outlet of the drain base 93. The flushing aid pipe 943 can be assembled separately from the drain base 93, or it can be integrally formed with the drain base 93. The diameter of the flushing aid pipe 943 gradually decreases to increase the fluid velocity at the outlet.

[0059] like Figure 7 As shown, the third water outlet channel 18 includes a cylindrical inner tube 182, with an outer tube 183 coaxially connected to the end of the inner tube 182. The outer tube 183 has two travel grooves, each including a vertical groove section 184 and a rotating groove section 185 connected to the vertical groove section. Figure 6 As shown, a protruding post 945 is provided at the end of the support pipe 941, and an L-shaped bracket 946 is provided at the bottom of the support pipe 941. The protruding post 945 is inserted into the end of the vertical groove section 184 along the vertical groove section 184 (as shown by arrow ① in the figure). Then, the support pipe 941 is rotated so that the protruding post 945 enters the rotating groove section 185 (as shown by arrow ② in the figure), thereby realizing the quick connection between the support pipe 941 and the third water outlet channel 18.

[0060] The principle of the water outlet is: 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 directed to the tangent direction parallel to the outer edge of the corresponding pump cavity (along the current rotation 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 directed to the tangent direction parallel to the outer edge of the corresponding pump cavity (against the current rotation direction), or is arranged at a small included angle α with the tangent direction. When the opening of the water outlet is directed to the tangent direction at a large included angle β with the outer edge of the corresponding pump cavity, and the included angle β>α, no matter whether the rotation is in the first direction or in 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°.

[0061] Combining Figure 14a 、 Figure 14b 、 Figure 14c 、 Figure 15 as shown, the setting principle of the first water outlet passage 16, the second water outlet passage 17 and the third water outlet passage 18 of the utility model is explained and illustrated by simple drawings. The first water outlet passage 16 comprises a first water outlet 161, the opening of the first water outlet 161 is directed to 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, and 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, the first water outlet passage 16 only needs to be provided with one first water outlet 161. In some embodiments, the first water outlet passage 16 is also provided with other water outlets, the flow of the other water outlets is extremely small, and also does not affect the realization of the effect of the application. The second water outlet passage 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 passage 17 is connected to the outside of the shell. The third water outlet passage 18 comprises a third water outlet 181, the opening of the third water outlet 181 is directed to 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; and the direction of the third 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, the third water outlet passage 18 only needs to be provided with one third water outlet 181. In some embodiments, the third water outlet passage 18 is also provided with other water outlets, the flow of the other water outlets is extremely small, and also does not affect the realization of the effect of the application.

[0062] As Figures 14a-14cIn this system, the first water outlet channel 16 has one first water outlet 161, the second water outlet channel 17 has two second water outlets 171, and the third water outlet channel 18 has one third water outlet 181. The outer edge of the pump chamber corresponding to the first water outlet 161 is point P1, and the tangent line along P1 (following the direction of W1) is the orientation of the first water outlet 161. The outer edge of the pump chamber corresponding to the third water outlet 181 is point P4, and the tangent line along P4 (following the direction of W1) is the orientation of the third water outlet 181.

[0063] The two second water outlets 171 of the second water outlet channel 17 are generally implemented in the following three ways:

[0064] (1) such as Figure 14a As shown, the second water outlet channel includes a second outlet A and a second outlet B; a second outlet A1711 and a second outlet B1712. The opening of the second outlet A1711 is set at an angle β with the tangent direction of the outer edge of the corresponding pump chamber. In the figure, the point on the outer edge of the pump chamber corresponding to the second outlet A1711 is P2. A tangent q1 is drawn along P2, and the opening of the second outlet A1711 is at an angle β1 = 52° with the tangent q1. The opening of the second outlet B1712 is parallel to the tangent direction of the outer edge of the corresponding pump chamber, or set at an angle α with the tangent direction, and the orientation of the second outlet B1712 is along the water flow direction of the impeller 3 rotating in the second direction. In the figure, the outer edge of the pump chamber corresponding to the second outlet B1712 is point P3. The tangent along P3 is the setting direction of the second outlet B, at which time the second outlet B is parallel to the second outlet A. When impeller 3 rotates along the W2 direction, water flows out from the second outlet A 1711 and the second outlet B 1712. Since the first outlet 161 and the third outlet 181 are tangentially opposite to the rotation direction at this time, water flow is basically not from the first outlet 161 and the third outlet 181. When impeller 3 rotates along the W1 direction, water flows out from the first outlet 161, the second outlet A 1711, and the third outlet 181. Since the second outlet B 1712 is tangentially opposite to the rotation direction at this time, water flow is basically not from the second outlet B 1712.

[0065] (2) For example Figure 14bAs shown, the second water outlet channel includes a second outlet B1712 and a second outlet C1713. The opening of the second outlet B1712 is oriented parallel to the tangent direction of the corresponding outer edge of the pump chamber, and the orientation of the second outlet B is along the water flow direction as the impeller rotates in the second direction. The opening of the second outlet C is oriented parallel to the tangent direction of the corresponding outer edge of the pump chamber, and the orientation of the second outlet C is along the water flow direction as the impeller rotates in the first direction. When the impeller 3 rotates in the W2 direction, water flows out from the second outlet B1712. Since the first outlet 161, the second outlet C, and the third outlet 181 are in the opposite tangent direction of rotation at this time, water does not flow out from the first outlet 161, the second outlet C, and the third outlet 181. When the impeller 3 rotates along the W1 direction, water flows out from the first outlet 161, the second outlet C 1713, and the third outlet 181. Since the second outlet B 1712 is in the opposite direction of the rotation at this time, water does not flow out from the second outlet B 1712.

[0066] (3) such as Figure 14c As shown, the second water outlet channel includes a second outlet B1712 and a second outlet D1714. The opening of the second outlet B1712 is parallel to the tangent direction of the corresponding outer edge P3 of the pump chamber (along W2), that is, the orientation of the second outlet B1712 is along the direction of water flow as the impeller rotates in the second direction. The opening of the second outlet D1714 forms an angle β5 = 48° with the tangent direction of the corresponding outer edge P3 of the pump chamber (along W1). When the impeller 3 rotates along the W2 direction, water flows out from the second outlet B1712 and the second outlet D. Since the first outlet 161 and the third outlet 181 are in the opposite direction of rotation at this time, water does not flow out from the first outlet 161 and the third outlet 181. When the impeller 3 rotates along the W1 direction, water flows out from the first outlet 161, the second outlet D 1714, and the third outlet 181. Since the second outlet B 1712 is in the opposite direction of the rotation tangent at this time, water does not flow out from the second outlet B 1712.

[0067] like Figure 15As shown, in this embodiment, the first water outlet channel 16 is provided with a first water outlet 161, the second water outlet channel 17 is provided with a second water outlet 171, and the third water outlet channel 18 is provided with a third water outlet 181. The first water outlet 161 corresponds to a point P5 on the outer edge of the pump cavity, and the tangent line along P5 (in the direction of W1) is the setting direction of the first water outlet 161. The opening direction of the second water outlet 171 is set at an angle β with the tangent direction of the corresponding pump cavity outer edge, and the angle β > 30°. In the figure, the point corresponding to the pump cavity outer edge of the second water outlet 171 is P6, and a tangent line q2 is drawn along P6, and the opening direction of the second water outlet 171 is at an angle β2 = 60° with the tangent line q2. The third water outlet 181 corresponds to a point P7 on the outer edge of the pump cavity, and the tangent line along P7 (in the direction of W1) is the setting direction of the third water outlet 181. When the impeller 3 rotates in the direction of W1, the water flow mainly flows out from the first water outlet 161 and the third water outlet 181, and some flows out from the second water outlet 171. When the impeller 3 rotates in the direction of W2, the water flow flows out from the second water outlet 171, and since the first water outlet 161 and the third water outlet 181 are opposite to the tangent direction of rotation at this time, the water flow basically does not flow out from the first water outlet 161 and the third water outlet 181.

[0068] By such a principle, when the impeller 3 rotates in the first direction, the water flow flows out from the first water outlet 161, the third water outlet 181, and at least one second water outlet 171 at the same time, and at this time the water flow of the second water outlet channel > 5L / min. When the impeller 3 rotates in the second direction, the water flow basically flows out from the second water outlet 171, and the water flow of the second water outlet channel > 8L / min; does not flow out from the first water outlet 161 and the third water outlet 181, or only a small amount of water flows out from the first water outlet 161 and the third water outlet 181. Through such a structure, the water pump of the utility model is suitable for two application scenarios of the closestool: when it is necessary to enter the drainage mode, the water flow needs to flow out from the first water outlet channel, the second water outlet channel, and the third water outlet channel at the same time; and when it is necessary to enter the washing, water replenishing, and wall moistening mode, the water flow only flows out from the second water outlet channel alone, so as to save the water consumption. The water pump of the utility model can also be suitable for other similar application scenarios.

[0069] Through the above principle description, combined with Figure 12 , 13, in the embodiment of the utility model, the second water outlet channel 17 is set 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. 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 setting 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. Figure 12 When the impeller 3 rotates along the W1 direction, water flows out from the first water outlet 161, the second water outlet A 1711 and the third water outlet 181 (the solid arrow direction in the figure is the water flow direction), and the water basically does not flow out from the second water outlet B 1712 at this time because the second water outlet B 1712 is opposite to the tangent direction of rotation. Figure 13 When the impeller 3 rotates along the W2 direction, water flows out from the second water outlet A 1711 and the second water outlet B 1712 (the dotted arrow direction in the figure is the water flow direction), and the water basically does not flow out from the first water outlet 161 and the third water outlet 181 at this time because the first water outlet 161 and the third water outlet 181 are opposite to the tangent direction of rotation.

[0070] As shown in Figure 11 and Figure 14a , in order to make the water not flow out from the first water outlet 161 and the third water outlet 181 when the impeller 3 rotates along the second direction (W2 direction), a wedge-shaped block 19 is further arranged on the inner wall surface of the pump cavity 14. The wedge-shaped block 19 is arranged at the end of the first water outlet 161 or the third water outlet 181, or two wedge-shaped blocks 19 are arranged at the same time, the wedge-shaped block 19 is arranged obliquely along the inner wall of the pump cavity 14, the front end surface of the wedge-shaped block 19 protrudes from the first water outlet 161 or the third water outlet 181, and the rear end surface is smoothly connected with the inner wall of the pump cavity 14. Through this arrangement, when rotating along the second direction, the water is blocked by the wedge-shaped block 19, which can further avoid flowing out from the first water outlet 161 or / and the third water outlet 181, but flow along the wedge-shaped block to pass the first water outlet 161 or / and the third water outlet 181.

[0071] Embodiment two

[0072] As shown in Figures 16-17 , the embodiment discloses an integrated water piece, which is different from the embodiment one in that: the embodiment does not arrange the flushing pipe, the water inlet 15, the first water outlet channel 16 and the second water outlet channel 17 are arranged on the water outlet cover 11 of the water pump, and the third water outlet channel 18 is not arranged.

[0073] The first water outlet channel 16 is connected to the drainage mechanism 92. When the first water outlet channel 16 is draining water, the drainage mechanism 92 of the water pump moves upward under the action of water pressure, and the piston in the drainage mechanism 92 moves upward, thereby opening the water sealing rubber 921 below the drainage mechanism 92, i.e. opening the water inlet of the drainage base 93, and the water source can flow out of the drainage base 93. The second water outlet channel 17 is connected to the outside of the shell 91 to be connected to the external washing pipeline 6.

[0074] As Figure 18 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 the tangent of the outer edge of the pump cavity P8, and the setting direction of the first water outlet 161 is along the tangent of P8 (in the direction of W1). The two second water outlets 171 are respectively a second water outlet A 1711 and a second water outlet B 1712. The opening direction of the second water outlet A 1711 is set at an angle β with the tangent direction of the corresponding pump cavity outer edge, and the angle β is greater than 30°. In the figure, the point of the second water outlet A 1711 corresponding to the pump cavity outer edge is P9, and a tangent q3 is drawn along P9. The opening direction of the second water outlet A 1711 is at an angle β3=50° with the tangent q3. The opening direction of the second water outlet B 1712 is parallel to the tangent direction of the corresponding pump cavity outer edge, or is set at an angle α with the tangent direction, and the angle α is less than or equal to 30°, and 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 of the second water outlet B 1712 corresponding to the pump cavity outer edge is P10, and the setting direction of the second water outlet B is along the tangent of P10. When the impeller 3 rotates in the direction of W1, the water flow mainly flows out of the first water outlet 161, and some water flow flows out of 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 out of the second water outlet B 1712. When the impeller 3 rotates in the direction of W2, the water flow flows out of 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 out of the first water outlet 161.

[0075] As Figure 19As 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 P11, and the tangent line along P11 (in the direction of W1) is the optimal setting direction of the first water outlet 161. Of course, in actual production, the angle may have a slight deviation, for example, the opening direction of the first water outlet 161 in the figure is at an angle α of 10° with the tangent direction q4 of the corresponding pump cavity outer edge, and the angle α = 10° can also achieve the technical effects of the utility model. The corresponding pump cavity outer edge of the second water outlet 171 in the figure is point P12, and a tangent line q5 is drawn along P12, and the opening direction of the second water outlet 171 is at an angle β4 = 90° with the tangent line q2. When the impeller 3 rotates in the direction of W1, water flows out from the first water outlet 161 and the second water outlet 171 at the same time. When the impeller 3 rotates in the direction of W2, water flows out from the second water outlet 171. Since the first water outlet 161 is opposite to the tangent direction at this time, water basically does not flow out from the first water outlet 161.

[0076] Through such a structure, the water pump of the utility model is suitable for two application scenarios of the closestool: when it is necessary to enter the drainage mode, water needs to flow out from the first water outlet channel and the second water outlet channel at the same time; and when it is necessary to enter the washing, water supplementing and wall moistening mode, water only flows out from the second water outlet channel alone, so as to save the water consumption.

[0077] Embodiment three

[0078] As Figures 20 to 21 shown, the embodiment discloses a closestool, which comprises a closestool body 8, a water inlet valve 7 and the integrated water piece of embodiment one or embodiment two.

[0079] The closestool body 8 comprises a toilet cavity 81 and a water tank 82, and a plurality of washing holes 811 are arranged on the wall surface of the toilet cavity 81, and a sewage outlet 812 is arranged at the bottom of the toilet cavity 81.

[0080] The water tank 82 can be a sunken water tank in Figures 20 to 21 , or a water tank protruding upward in a traditional closestool. When it is a sunken water tank, the potential energy of the water tank 82 is small, and therefore it is preferable to set the integrated water piece of embodiment one, so as to realize power-assisted flushing through the power-assisted pipe 94, so as to make up for the defect of insufficient force due to small potential energy.

[0081] The water tank 82 is provided with a water inlet and a drainage outlet, the water inlet valve 7 is installed at the water inlet, the water inlet valve 7 is a device for controlling water inlet, which is a general device that can be purchased on the market, and will not be described in detail here. The integrated water piece is installed in the water tank 82, and the drainage base 93 is installed at the drainage outlet.

[0082] The first water outlet channel 16 is communicated with the drainage mechanism 92, and is used for driving the drainage mechanism 92 to open, so that the water in the water tank 82 flows into the drainage base 93. The drainage base 93 is connected with the drain outlet 812 through a drainage elbow 5, so that the water flows into the drain outlet 812 to realize flushing, as shown in the figure. Figure 21 The second water outlet channel 17 is connected with a washing pipeline 6, and the other end of the washing pipeline 6 is connected to the washing hole 811, so that the water flows out through the washing hole 811 to realize water supplement or wall washing of the upper wall surface of the toilet bowl.

[0083] The third water outlet channel 18 is connected to one end of an auxiliary flushing pipeline 94, the other end of the auxiliary flushing pipeline 94 is connected to the outlet of the drainage base 93, and the auxiliary flushing pipeline 94 extends into the drainage elbow 5, so that the water flow of the third water outlet channel 18 flows out from the auxiliary flushing pipeline 94 to realize auxiliary flushing.

[0084] When the motor 2 controls the impeller 3 to rotate along the direction W1, the water flow flows out from both the first water outlet channel 16 and the second water outlet channel 17, and the wall surface above the toilet bowl 81 is washed, and at the same time, the drain outlet 812 is flushed, and the splashes and dirt splashed during flushing are simultaneously flushed away by the water flow flowing out of the washing hole 811. When the motor 2 controls the impeller 3 to rotate along the direction W2, the water flow flows out from the second water outlet channel 17, and the wall surface above the toilet bowl 81 is washed or moistened or supplemented with water. In this mode, the first water outlet channel 16 does not flush water, which saves water source and is flexible in use scenarios.

[0085] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
