Description

Technical Field

[0001] The invention relates to the technical field of bathrooms, in particular to an integrated water component and an intelligent toilet using the integrated water component. Background Art

[0002] The existing toilet design requires flushing and scrubbing. When flushing, a drainage control pump is used to control the flushing to achieve the purpose of flushing. When scrubbing, a scrubbing pump is used to control the wall of the toilet. Based on the needs of the two functions, the existing drainage control pump and scrubbing pump are both independently set and arranged in the water tank, which requires a large space and is troublesome to install and after-sales.

[0003] In addition, there are the following design problems in the toilet design:

[0004] 1. When the drainage control pump is working, it is affected by the water level in the water tank. When the water level in the water tank is too low, it is lower than the interface of the water inlet of the drainage control pump, resulting in failure of suction, idling of the impeller, and failure of the drainage control pump.

[0005] 2. The design of modern toilets tends to adopt a sunken water tank design for the sake of aesthetics. The jet outlet uses the water potential energy in the sunken receiving chamber when flushing. Since the water potential energy of the sunken water tank is small, the manufacturing process of the toilet flushing pipe is required to be high. In some cases, lax control of the toilet manufacturing process may lead to insufficient flushing jet force, resulting in failure to flush cleanly.

[0006] 3. The existing micro brushless DC water pump is used in toilets. Under normal circumstances, the water inlet of the end cover outputs the water in the container to the water outlet. If the water outlet of the end cover is connected to a pipe, when the pressure of the residual liquid in the pipe at the water outlet of the end cover and the pressure of the water in the toilet at the water inlet of the end cover reach equilibrium, a sealed space filled with air is formed in the water passage cavity, which causes "air trapping". At this time, the negative pressure generated by the water pump impeller in this sealed space filled with air is not enough to break this pressure balance, which will cause the impeller to run idle, the water pump to fail to work, and it is impossible to achieve the function of outputting water from the water inlet to the water outlet.

[0007] 4. Existing toilet water fittings have a single function and cannot meet multiple functional needs.

[0008] Therefore, it is necessary to further improve the structure of existing toilet water parts and intelligent toilets to solve the above-mentioned problems. Summary of the invention

The drainage base 6 is installed below the housing, and the drainage mechanism 3, the drainage control pump 4 and the brush pump 5 are installed in the housing. When in use, the present invention is installed in the water tank of the toilet.

[0060] Combination Fig. 9 As shown, the drainage mechanism 3 includes a valve body 31, a return spring 32, a piston 33 and a water-sealing rubber 34. The return spring 32 is arranged in the inner cavity of the valve body 31, and the return spring 32 is located above the piston 33. A drainage liquid chamber 331 connected to the water inlet of the valve body is arranged below the piston 33, one end of which is slidably arranged in the valve body 31, and the other end extends out of the valve body 31 and is connected to the water-sealing rubber 34 at the end. The water-sealing rubber 34 is adapted to the outlet seal of the drainage base 6. When the piston 33 moves downward, the water-sealing rubber 34 seals the drainage base 6. When the piston 33 moves upward, the water-sealing rubber 34 opens to achieve drainage. As needed, the outlet of the drainage base 6 can also be connected to a water supply pipe 63 or a leakage pipe 64. In this embodiment, the water supply pipe 63 and the leakage pipe 64 are connected at the same time, such as Figure 3 shown.

[0061] like Figure 2 As shown, in this embodiment, the housing includes an upper housing 1 and a lower housing 2. Figure 7 As shown, the lower shell 2 is provided with a water tank 21 and a filter screen 23. The drainage control pump 4 and the valve body 31 are installed on the lower shell 2, so that the water inlet of the drainage control pump 4 (B1 in the figure) is located in the water tank 21. Figure 8 As shown, a mounting plate 311 is connected below the water inlet (A1 in the figure) of the valve body 31, a U-shaped fixing groove 312 is provided at the end of the mounting plate 311, and the drainage control pump 4 is installed on the U-shaped fixing groove 312, so that the water outlet (B2 in the figure) of the drainage control pump 4 is connected to the water inlet of the valve body 31.

[0062] In this embodiment, a water storage cover plate 7 is also installed above the water storage tank 21, and filter holes 71 are provided above the water storage cover plate 7 and the side wall of the water storage tank 21. In other embodiments, the water storage cover plate 7 and the water storage tank 21 may not be provided. The water storage cover plate 7 is provided to perform a secondary filtration on the water in the water tank, and at the same time, it plays a supporting role for the valve body 31 and the drainage control pump 4. The water storage tank 21 is provided so that the water inlet of the drainage control pump 4 is located in the water storage tank 21 and is not affected by the height of the liquid level in the water tank.

[0063] Combination Figure 5As shown, the upper shell 1 is provided with a through hole 11 for water source in the water supply tank to enter. A mounting portion 17 is also provided below the upper shell 1, and the scrubber pump 5 is fixed to the mounting portion 17. The water inlet of the scrubber pump 5 (C1 in the figure) faces downward, and the filter screen 23 is correspondingly arranged at the position of the water inlet of the scrubber pump 5 to filter the water source entering the water inlet of the scrubber pump 5. The water outlet of the scrubber pump 5 (C2 in the figure) extends out of the upper shell 1. Fig.11 As shown, a water passage chamber 51 is provided inside the scrubbing pump 5, an impeller 52 of the scrubbing pump 5 is located in the water passage chamber 51, a pressure relief hole 53 is provided on the side wall of the water passage chamber 51, and the water inlet, water outlet and pressure relief hole 53 of the scrubbing pump 5 are all connected to the water passage chamber 51.

[0064] like Figure 5 , Figure 7 As shown, the upper shell 1 and the lower shell 2 are positioned and connected by the following structure:

[0065] (1) A plurality of positioning pins 12 are provided on the inner wall of the upper shell 1, and a plurality of positioning columns 24 are provided on the edge of the lower shell 2. The positioning pins 12 cooperate with the positioning columns 24 for positioning.

[0066] (2) A concave point 13 is provided on the inner wall of the upper shell 1 , and an elastic hook 25 is provided on the edge of the lower shell 2 , and the elastic hook 25 is engaged with the concave point 13 .

[0067] The outer wall of the upper shell is provided with a snap-on 14 on both sides. The middle of the snap-on 14 is fixed to the upper shell 1, and the two ends are cantilevered. The upper end of the snap-on 14 is a pressing portion 141 for hand pressing. The lower end of the snap-on 14 is provided with a snap-on 142. The outer periphery of the drain base 6 is provided with a flange 62. The snap-on 142 is clamped on the flange 62, thereby realizing the connection between the drain base 6 and the upper shell 1.

[0068] When disassembly is required, the pressing parts 141 of the two buckles 14 are pressed by hand at the same time, the upper end of the buckle 14 is pressed inward, and the lower end is tilted outward, so that the buckle 142 at the lower end is separated from the flange 62. The upper shell 1 is gently opened upward to separate the elastic hook 25 from the concave point 13, thereby realizing the disassembly of the upper shell 1 and the lower shell 2.

[0069] like Figure 2 As shown, a plurality of evenly distributed convex ribs 27 are provided at the connection between the lower shell 2 and the drain base 6, and a plurality of corresponding grooves 61 are provided on the drain base 6. The grooves 61 of the drain base 6 are clamped at the convex ribs 27. By setting the convex ribs 27 and the grooves 61 together, the anti-rotation effect can be achieved. When rotating manually, a certain force needs to be applied, and there is a clamping prompt sound when rotating.

[0070] Combination Fig. 9 As shown, a wire control pull rope 81 and a wire control device 82 are also connected to the valve body 31. A decorative cover 9 is also provided on the upper shell 1 and is connected to the upper shell 1. A wire outlet hole 91 is provided on the decorative cover 9. Figure 6 As shown, a wire outlet hole 15 and a wire groove 16 are provided on the upper shell 1. The wire control pull rope 81 and the connection wires of the drainage control pump 4 and the washing pump 5 pass through the wire outlet hole 15 and are gathered along the wire groove 16 to the wire outlet hole 91 of the decorative cover 9 and extend out. The wire control pull rope 81 is connected to the wire control device 82.

[0071] The installation process of the present invention is as follows:

[0072] 1. Install the drainage control pump 4 on the connecting plate 311, and connect the water outlet of the drainage control pump 4 to the water inlet of the valve body 31. Install and fix the drainage control pump 4 and the valve body 31 to the lower shell as a whole, so that the drainage control pump 4 is located in the water storage tank 21.

[0073] 2. Install the water storage cover plate 7 so that the water storage cover plate 7 is snap-connected to the water storage tank 21 .

[0074] 3. Install the scrubbing pump 5 on the mounting portion 17 of the upper shell 1 . The water inlet of the scrubbing pump 5 is located above the filter screen 23 .

[0075] 4. Connect the drain base 6 to the lower shell 2 so that the groove 61 of the drain base 6 is snap-fitted to the convex rib 27 .

[0076] 5. Install the upper shell 1 and the washing pump 5 on the lower shell 2 so that the upper shell 1 and the lower shell 2 are fixed together, and the upper shell 1 is connected to the drainage base. Pass the wire control pull rope 81 and the connection wires of the drainage control pump 4 and the washing pump 5 through the outlet hole 15 and gather along the wire groove 16.

[0077] 6. Install the decorative cover 9 so that the wire control cord 81 and the connecting wire pass through the wire outlet hole 91.

[0078] The drainage device of the present invention is a dual control mode: Fig. 9 As shown, the water in the water tank passes through the through hole 11 and the filter hole 71 to fill the water tank 21. When the valve body 31 is in the closed state, the water sealing rubber 34 seals the outlet of the drain base 6. When the mechanical control method is adopted, it is only necessary to pull the wire control pull rope 81 to drive the piston 33 to move upward, so that the water sealing rubber 34 is separated from the drain base 6, and then the outlet of the drain base 6 is opened, and the water in the water tank is flushed into the toilet from the outlet of the drain base 6. Fig.10As shown, when the electric control method is adopted, the drainage control pump 4 is started, and the water in the water storage tank 21 is pumped out by the drainage control pump 4 and enters the drainage liquid chamber 331 from the water outlet of the drainage control pump 4. Under the action of water pressure, the entire piston 33 slides upward, and the reset spring 32 is compressed, thereby opening the outlet of the drainage base 6, and the water source in the water tank flows from the drainage base 6 into the toilet. When the liquid level of the water in the water tank is lower than the water inlet of the drainage control pump 4, since the water source is originally stored in the water storage tank 21, the normal operation of the drainage control pump 4 is guaranteed and is not affected by the water level in the water tank. When the toilet is washed, the scrubbing pump 5 is started, and the water in the water tank is pumped out by the scrubbing pump 5 and flushed out from the water outlet of the scrubbing pump 5 into the scrubbing pipe to scrub the inner wall of the toilet.

[0079] Embodiment 2

[0080] like Figure 12-13 As shown, this embodiment discloses a smart toilet, including a toilet body 10, a water inlet valve 20 and the integrated water fittings of the first embodiment.

[0081] The toilet body 10 is divided into a toilet chamber 101 and a water receiving chamber 102. A washing hole 103 is provided on the partition wall between the toilet chamber 101 and the water receiving chamber 102. The water inlet valve 20 and the integrated water parts are arranged in the water receiving chamber 102. The water inlet valve 20 delivers water to the water receiving chamber 102.

[0082] The working principle of the drainage of the integrated water component in this embodiment has been described in detail in the first embodiment, and will not be repeated here. The following further explains the principle of the washing process.

[0083] The washing pipe 30 is fixed to the inner wall of the toilet body 10 by a fixing buckle or a connecting belt, so that the position of the washing pipe 30 is higher than the working water level set in the receiving water chamber 102. Fig.11 The water source flows upward from the outlet of the scrubbing pump 5 into the scrubbing pipe 30 and is higher than the working water level in the receiving water cavity, and then flows into the scrubbing hole 103, which can prevent siphoning and avoid water backflow.

[0084] When the smart toilet starts flushing, the main control unit of the smart toilet drives the scrubber pump 5 to work according to actual needs to achieve the best flushing and scrubbing effect. Since the scrubber pump 5 with the pressure relief hole 53 is used, the water passage chamber 51 of the scrubber pump 5 (i.e., the impeller working space) and the water receiving chamber 102 of the smart toilet form a communicating vessel. Therefore, when the water level in the water receiving chamber 102 rises, even if there is residual water in the scrubber pipe 30, the air in the water passage chamber 51 will be discharged from the pressure relief hole 53 as the water level at the water inlet of the scrubber pump 5 rises. Fig.11The water flows normally into the water chamber 51 from the water inlet, and the impeller 52 rotates normally to drive the water out from the water outlet, thereby preventing the water chamber 51 from being affected by the residual water in the washing pipe 30 and causing air to be trapped, causing the impeller 52 to run idle. The water discharged from the water outlet of the washing pump 5 flows into the toilet chamber 101 through the washing pipe 30 to wash the toilet chamber 101.

[0085] like Fig.12 As shown, a water supply pipe 63 and a water leakage pipe 64 are provided on the drainage base 6. One end of the water supply pipe 63 is connected to the drainage base outlet, and the other end is connected to the water inlet valve 20 through a water supply conduit 40, so as to realize the water supply function of the toilet. One end of the water leakage pipe 64 is connected to the drainage base outlet, and the other end is connected to the cover plate of the smart toilet (not shown in the figure) through a water leakage conduit 50, so as to realize the function of collecting and discharging the water on the toilet cover.

[0086] Embodiment 3

[0087] This embodiment discloses an integrated water device, which has the functions of drainage, washing and flushing. The difference between this embodiment and the first embodiment is that it also includes a flushing pump 60 and a flushing pipe 70, and the flushing pump 60 and the flushing pipe 70 are connected through a flushing pipe. The inlet end of the flushing pipe 70 is connected to the pressurized water source end, and the outlet end thereof is inserted into the drainage base 6 and communicates with the water outlet of the drainage base 6.

[0088] like Fig.14 As shown, the flushing pump 60 can be integrated in the housing, and the water outlet of the flushing pump 60 extends out of the housing.

The upper housing 1 and the lower housing 2 are assembled, so that the drainage mechanism 3, the drainage control pump 4, the scrubbing pump 5 and the flushing pump 60 are all arranged in the housing.

[0089] like Fig.15 , Fig.16 As shown, the booster pump 60 may not be integrated in the housing, and a mounting frame is provided on the side of the drainage base 6 for installing the booster pump 60. A filter screen 23 may be provided at the water inlet of the booster pump 60.

[0090] A water passage cavity is provided inside the flushing pump 60, and the impeller of the brush pump 60 is located in the water passage cavity. A flushing pump pressure relief hole 601 is provided on the side wall of the water passage cavity. The water inlet, water outlet and flushing pump pressure relief hole 601 of the flushing pump 60 are all connected to the water passage cavity of the flushing pump. The principle of providing the flushing pump pressure relief hole 601 is similar to the pressure relief hole 53 of the brush pump 5: the water passage cavity of the flushing pump 60 and the receiving water cavity 102 of the smart toilet form a communicating vessel to avoid air entrapment in the water passage cavity and ensure the normal operation of the impeller in the flushing pump 60.

[0091] Embodiment 4

[0092] like Fig.17 As shown, this embodiment discloses a smart toilet, which has the functions of drainage, washing and flushing. The difference between this embodiment and the second embodiment is that this embodiment includes the integrated water parts of the third embodiment.

[0093] The working principle of the drainage process of the smart toilet has been described in detail in Example 1, and the principle of the washing process has been described in detail in Example 2. The following further describes the principle of flushing assistance.

[0094] Combination Fig.18 As shown, the boosting pipe 80 is set to be U-shaped, one end of the boosting pipe 80 is connected to the boosting pump 60, and the other end is connected to the boosting pipe 70. In this embodiment, the boosting pipe 70 uses a venturi tube, and the diameter of the outlet end of the venturi tube gradually decreases, which can better increase the flow rate of the fluid and achieve a better boosting effect. The venturi tube can be set with several ( Fig.17 Set one in the middle, Fig.18 Two are provided in the middle). If there is more than one venturi tube, several branch tubes can be connected to the end of the booster pipe 80 through an adapter, and each branch tube can be connected to the venturi tube separately. The venturi tube can be integrally formed or assembled from several sections of the tube body. By adopting the assembly form, the venturi tube can be assembled with structures of different materials as needed, and can also be arranged in different directions according to different needs. Fig.18 In the embodiment, the venturi tube can be made into a U-shape or an L-shape as required, so that the water flow at the outlet end of the venturi tube is sprayed in different directions.

[0095] An anti-siphon hole 801 is provided above the flushing-assisting pipe 80 . The anti-siphon hole 801 is higher than the working water level set in the water receiving chamber 102 , so as to prevent siphoning.

[0096] When the smart toilet starts flushing, the main control unit independently drives the flushing pump 60 to work as needed. The flushing pump 60 pumps the water in the water receiving chamber 102 of the toilet into the flushing pipe 70. The flow rate of the flushing water flow at the inlet end of the flushing pipe 70 is a. The outlet end of the flushing pipe 70 passes through the small cross-section pipe diameter and then sprays out. The flow rate of the flushing water flow increases to a'. As the flow rate at the outlet increases, the flow rate of the water flow discharged from the drainage base 6 also increases, so that the water flow rate increases from b to b', thereby effectively improving the flushing capacity of the toilet chamber 101.

[0097] Embodiment 5

[0098] This embodiment discloses a smart toilet that has the functions of drainage, washing and flushing. Fig.19As shown, the difference from the second embodiment is that a flushing pipe 70 is provided on the drainage base 6 of the integrated water fitting, the inlet end of the flushing pipe 70 is connected to the water inlet valve 20 through a water supply pipe 90, and the water supply pipe 90 is provided with a solenoid valve 100 for controlling the water flow in the water supply pipe 90.

[0099] When the smart toilet starts flushing, the main control unit independently drives the solenoid valve 100 to work as needed, and the water in the water inlet valve 20 enters the flushing pipe through the water supply pipe 90. The diameter of the outlet end of the flushing pipe 70 gradually decreases. Due to the reduction in the diameter, the restricted flow increases in velocity when passing through the reduced flow section. The flushing water flow of the flushing pipe 70 is ejected from the pipe mouth, driving the water flow velocity in the drainage base 6 to increase, and further driving the water flow velocity in the flushing pipe of the smart toilet, thereby increasing the jet force for flushing the toilet chamber 101.

[0100] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
