Description

Technical Field

[0001] The invention relates to the technical field of bathrooms, in particular to an integrated water fitting. 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 requirements 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, high cost, and troublesome installation 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

DETAILED DESCRIPTION

[0048] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Embodiment 1

[0050] like Figure 1-Figure 3 As shown, this embodiment discloses an integrated water device, including a housing 1, a drainage mechanism 2, a dual-way lift flow distribution assembly 3, a micro pump 4 and a drainage base 5. When in use, the present invention is installed in a water tank or a sunken water cavity of a toilet.

[0051] The dual-path lift flow distribution component of the present embodiment adopts an existing three-way valve, which includes a flow water inlet 31, a washing water outlet 32 ​​and a drainage control water outlet 33 which are interconnected.

[0052] The drainage mechanism 2, the dual-way lift flow distribution assembly 3, and the micro pump 4 are installed in the housing 1, the drainage base 5 is installed below the housing 1, and the water inlet of the micro pump 4 is connected to the water source. The flow inlet 31 is connected to the water outlet of the micro pump, the washing outlet 32 ​​extends to the outside of the housing 1, and the drainage control outlet 33 is connected to the drainage mechanism 2.

[0053] Combination Figure 6As shown, the drainage mechanism 2 includes a valve body 21, a return spring 22, a piston 23 and a water-sealing rubber 24. The return spring 22 is arranged in the inner cavity of the valve body 21, and the return spring 22 is located above the piston 23. A drainage liquid chamber 231 connected to the water inlet of the valve body is arranged below the piston 23, one end of which is slidably arranged in the valve body 21, and the other end extends out of the valve body 21 and is connected to the water-sealing rubber 24 at the end. The water-sealing rubber 24 is adapted to the outlet seal of the drainage base 5. When the piston 23 moves downward, the water-sealing rubber 24 seals the drainage base 5. When the piston 23 moves upward, the water-sealing rubber 24 opens to achieve drainage. As needed, the outlet of the drainage base 5 can also be connected to a water supply pipe 51 or a leakage pipe 52. In this embodiment, the water supply pipe 51 and the leakage pipe 52 are connected at the same time, such as Figure 3 The water supply pipe 51 is connected to the water inlet valve 102 of the smart toilet to realize the water supply function of the toilet. The leakage pipe 53 is connected to the cover plate of the smart toilet to realize the function of collecting and discharging the water on the toilet cover plate.

[0054] In this embodiment, the housing includes an upper housing 11 and a lower housing 12. The micro pump 4 and the valve body 21 are mounted on the lower housing 12. The lower housing 12 is provided with a filter screen 13 at a position corresponding to the water inlet of the micro pump 4. Figure 2 shown.

[0055] Combination Figure 8 As shown, a micropump water chamber is provided inside the micropump 4, the impeller of the micropump is located in the micropump water chamber, a third pressure relief hole 41 is provided on the side wall of the micropump water chamber, and the water inlet, water outlet and third pressure relief hole 41 of the micropump 4 are all connected to the micropump water chamber.

[0056] The upper shell 11 is provided with a clip 14 on both sides of the outer wall. The middle of the clip 14 is fixed to the upper shell 11, and the two ends are cantilevered. The upper end of the clip 14 is a pressing portion 141 for hand pressing. The lower end of the clip 14 is provided with a clip 142, and the outer periphery of the drain base 6 is provided with a flange 53, and the clip 142 is clamped on the flange 53, thereby realizing the connection between the drain base 5 and the upper shell 11.

[0057] 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 11 is gently pried upward to realize the disassembly of the upper shell 1 and the lower shell 2.

[0058] The integrated drainage device of the present invention is a dual control mode: Figure 6As shown, when the valve body 21 is in the closed state, the water-sealing rubber 24 seals the outlet of the drain base 5. When the mechanical control method is adopted, it is only necessary to pull the wire control pull rope to drive the piston 23 to move upward, so that the water-sealing rubber 24 is separated from the drain base 5, and then the outlet of the drain base 5 is opened, and the water in the water tank is flushed into the toilet from the outlet of the drain base 5. When the electric control method is adopted, the micro pump 4 is started, and a part of the water in the water tank is pumped out by the micro pump 4 from the drainage control outlet 33 into the drainage liquid cavity 231, and the other part of the water enters the toilet's washing pipe 103 from the washing outlet 32. Figure 7 As shown, as water enters the drainage liquid chamber 231, the entire piston 23 inside the valve body 21 slides upward under the action of water pressure, and the return spring 22 is compressed, thereby opening the outlet of the drainage base 5, and the water source in the water tank flows from the drainage base 5 into the toilet. Fig.13 As shown, the water from the washing water outlet 32 ​​flows into the toilet seat cavity wall through the washing pipe 103 to wash the toilet seat cavity.

[0059] Embodiment 2

[0060] like Figure 4-12 As shown, this embodiment discloses an integrated water fitting, and the difference between this embodiment and the first embodiment is that the dual-way lift flow distribution assembly 3 of this embodiment includes a distribution body 34 with a hollow cavity and a delay mechanism 6 located inside the distribution body 34. A mounting plate 25 is connected below the water inlet of the outer wall of the valve body 21 of the drainage mechanism 2, and the dual-way lift flow distribution assembly 3 is fixed on the mounting plate 25, so that the drainage control water outlet 33 is connected to the water inlet of the valve body 21.

[0061] Combination Figure 8 As shown, the delay mechanism includes a water-dividing piston 61, a delay spring 62 and an adjusting member. The adjusting member includes an adjusting knob 63 and an adjusting plate 64 fixedly connected to the adjusting knob. The adjusting plate 64 is located inside the distribution body 34, and the adjusting knob 63 extends out of the distribution body 34. The adjusting member is installed on the distribution body 34 so as to be movable up and down. For example, in this embodiment, a spiral transmission connection is adopted: a threaded hole is provided above the distribution body 34, and an external thread is provided on the outer wall of the adjusting knob 63. The adjusting knob 63 is inserted into the threaded hole and is spirally connected to the distribution body 34. Other up and down movement methods can also be adopted, such as controlling the up and down movement of the adjusting plate by a motor push rod.

[0062] The water-dividing piston 61 divides the hollow cavity of the distribution body 34 into an upper cavity and a lower cavity, the delay spring 61 is located in the upper cavity, the upper end of the delay spring 62 abuts against the adjustment plate 64, and the lower end of the delay spring 62 abuts against the water-dividing piston 61. A piston limiting boss 341 is provided in the distribution body cavity, and the water-dividing piston 61 is limited above the piston limiting boss 341.

[0063] like Figure 8 As shown, when the delay spring 62 is in the initial state, the water-dividing piston 61 is located between the washing water outlet 32 ​​and the drainage control water outlet 33. In this embodiment, the washing water outlet 32 ​​is located below the drainage control water outlet 33, and only the washing water outlet 32 ​​is connected to the flow water inlet 31. Fig. 9 As shown in the figure, after the water pressure acts on the water-dividing piston 61 to compress the delay spring 62, the washing water outlet 32 ​​and the drainage control water outlet 33 are both connected to the flow water inlet 31. In this embodiment, the toilet is controlled to wash first, and then the water is drained. By exchanging the positions of the washing water outlet 32 ​​and the drainage control water outlet 33, it is also possible to control the drainage of the toilet first, and then wash. Fig.10 As shown, by moving the adjustment knob 63 up and down, the compression length of the delay spring 62 can be adjusted, thereby adjusting the elastic force of the delay spring 62 to achieve different delay requirements.

[0064] like Fig.11 , Fig.12 As shown, in other embodiments, the delay mechanism may only include the water-dividing piston 61 and the delay spring 62, the upper end of the delay spring 62 abuts against the upper wall of the distribution body 34, and the lower end of the delay spring 62 abuts against the water-dividing piston 61. By selecting a suitable delay spring, the requirement of upper outlet delay is achieved.

[0065] like Fig. 9 As shown, in order to prevent "air entrapment" caused by excessive air in the distribution body, a first pressure relief hole 35 is provided above the distribution body 34, and a second pressure relief hole 36 is provided on the water distribution piston 61, so that the air can be discharged to the outside of the distribution body in time.

[0066] By reasonably setting the internal cavity volume flow rate, water inlet diameter, washing outlet diameter and drainage control outlet diameter of the dual-way lift flow distribution component, the lift of the micro pump outlet can be 4-12 meters, the flow rate can be 15-25L / minute; the lift of the drainage control outlet can be 3-10 meters, the flow rate can be 3-10L / minute; the lift of the washing outlet can be 3-5 meters, and the flow rate can be 12-18L / minute. This meets the needs of smart toilet washing and drainage.

[0067] Embodiment 3

[0068] like Fig.14 , Fig.15 As shown, this embodiment discloses an integrated water device, which has the functions of drainage, washing and flushing. This embodiment adds a flushing pump 7 and a flushing pipe 8 on the basis of the first or second embodiment. The flushing pump 7 and the flushing pipe 8 are connected by a flushing pipe 9. The inlet end of the flushing pipe 8 is connected to the pressurized water source end, and the outlet end thereof is inserted into the drainage base 5 and communicates with the water outlet of the drainage base 5.

[0069] like Fig.14 As shown, the booster pump 7 is installed on the side of the drainage base 5, and a mounting frame is provided on the drainage base 5 for installing the booster pump 7. A filter screen 71 can be provided at the water inlet of the booster pump 7. In other embodiments, the booster pump 7 can also be integrated in the housing 1, and the water outlet of the booster pump 7 extends out of the housing 1.

[0070] like Fig.15 As shown, a water passage cavity is provided inside the flushing pump 7, and the impeller of the brush-assisting pump 7 is located in the water passage cavity. A fourth pressure relief hole 72 is provided on the side wall of the water passage cavity, and the water inlet, water outlet and fourth pressure relief hole 72 of the flushing pump 7 are all connected to the water passage cavity of the flushing pump. The principle of setting the fourth pressure relief hole 72 is similar to the third pressure relief hole 41 of the micro pump: the water passage cavity of the flushing pump 7 and the water in the water tank 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 7.

[0071] like Fig.15 As shown, the boosting pipe 9 is set to be U-shaped, one end of the boosting pipe 9 is connected to the boosting pump 7, and the other end is connected to the boosting pipe 8. In this embodiment, the boosting pipe 8 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.15 Two are arranged in the middle). If there is more than one venturi tube, several branch pipes can be connected to the end of the auxiliary flushing pipe 9 through an adapter, and each branch pipe can be connected to the venturi tube separately. The venturi tube can be integrally formed or assembled from several sections of pipe body. The assembly form allows the venturi tube to be assembled with structures of different materials as needed, and can also be set in different directions according to different needs. The venturi tube can be made into a U-shape or an L-shape as needed, so that the water flow at the outlet end of the venturi tube is sprayed in different directions.

[0072] An anti-siphon hole 91 is provided above the flushing-assisting pipe 9. The anti-siphon hole 91 is higher than the working water level set in the water cavity to prevent siphoning.

[0073] When the smart toilet starts flushing, the main control unit independently drives the flushing pump 7 to work as needed. The flushing pump 7 pumps the water in the water cavity of the toilet into the flushing pipe 8. The flow rate of the flushing water flow at the inlet end of the flushing pipe 8 is a. The outlet end of the flushing pipe 8 is sprayed out after passing through the small cross-section pipe diameter. The flow rate of the flushing water flow increases to a'. Due to the increase in the flow rate at the outlet end, the flow rate of the water flow discharged from the drainage base 5 is also increased, so that the water flow rate increases from b to b', thereby effectively improving the flushing capacity of the toilet cavity.

[0074] Embodiment 4

[0075] like Fig.16As shown, this embodiment discloses an integrated water fitting, which has the functions of drainage, washing and flushing. This embodiment adds a flushing pipe on the basis of the first or second embodiment, and the inlet end of the flushing pipe 8 is connected to the water inlet valve 102 of the toilet through the water supply pipe 10, and the water supply pipe 10 is provided with a solenoid valve 101 for controlling the water flow in the water supply pipe 10.

[0076] When the smart toilet starts flushing, the main control unit independently drives the solenoid valve 101 to work as needed, and the water in the water inlet valve 102 enters the flushing-assisting pipe 8 through the water supply pipe 10. The diameter of the outlet end of the flushing-assisting pipe 8 gradually decreases. Due to the reduction in the diameter, the restricted flow increases in velocity when passing through the reduced flow section. The flushing-assisting water flow of the flushing-assisting pipe 8 is ejected from the pipe mouth, driving the water flow velocity in the drainage base 5 to increase, further driving the water flow velocity in the flushing pipe of the smart toilet, thereby increasing the jet force for flushing the toilet cavity.

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.
