Description

Technical Field

[0001] The invention relates to the field of toilets, and in particular to a water conveying system for toilets. Background Art

[0002] At present, the water transport system of toilets usually adopts a water distributor similar to a tee. The water distributor is provided with a water inlet for communicating with the main water outlet pipe, and the two water outlets correspond to two water distribution channels respectively. The water terminals are connected through the water distribution channels. The water distributor is installed on the water channel, and the water channel is switched by operating the switching device in the water distributor. However, compared with the traditional toilet, the existing toilet has added genital and anal flushing devices. Once the required water channel is added, it is necessary to add the corresponding water distributor for control, which not only increases the corresponding cost, but also is not conducive to the actual application of the user. In addition, the existing water transport system has a single structure and cannot realize the functions of heating and multi-water channel switching at the same time. Summary of the invention

[0005] Preferably, the end surface of the ceramic stator is provided with a third arc groove, and the two second water outlets are interconnected through the third arc groove. The side of the ceramic stator is provided with a plurality of arc-shaped concave positioning grooves, and the positioning grooves and the arc-shaped protrusions provided on the inner wall of the first shell body form a snap fit, thereby limiting the rotational freedom of the ceramic stator. The upper end of the first water outlet pipe is provided with an arc tube portion, and the arc tube portion covers and connects the two first water outlets, and also includes a sealing gasket, which is located between the ceramic stator and the bottom of the first shell body, and the sealing gasket is provided with each through hole corresponding to the first arc hole and the second through hole group, and the sealing gasket is provided with a third arc hole corresponding to the two first water outlets, and the two first water outlets are interconnected through the third arc hole. The provision of the sealing gasket can not only connect the two second water outlets, but also effectively improve the sealing performance of the first through hole group and the second through hole group.

[0006] Preferably, the knob includes a wrench assembly, a rotating shaft, and a fixing frame. The wrench assembly, the rotating shaft, and the ceramic movable plate are fixedly connected in sequence. The rotating shaft passes through a center hole provided on the fixing frame. The fixing frame is fixedly connected to the upper end of the first outer shell. An eccentric groove is provided on the side of the fixing frame relative to the center hole. An elastic top position assembly is installed in the eccentric groove. The upper end of the elastic top position assembly and the arc-shaped limit groove provided on the lower end of the wrench assembly form abutment fit. The arc-shaped limit groove is provided with three evenly distributed gear slots. Adjacent gear slots are directly separated by an arc-shaped buffer portion provided. The elastic top position assembly includes a first spring and a top position member installed on the first spring. The top position member can move between three different gear slots. The user directly rotates the wrench assembly, and the wrench assembly drives the rotating shaft, and the rotating shaft drives the ceramic movable plate to rotate relative to the ceramic fixed plate. The presence of the elastic top position assembly and the arc-shaped limit groove can effectively prevent the wrench assembly from rotating at an excessive angle. When the top position piece moves among the three different gear slots, it will pass through the arc-shaped buffer portion and enter different gear slots. At this time, the top position piece will feedback appropriate damping to the knob, so that the user can feel whether the gear adjustment is completed. In addition, the existence of the arc-shaped buffer portion can also effectively prevent the top position piece from automatically detaching from its existing gear slot, thereby avoiding affecting the use of the product.

[0007] Preferably, the wrench assembly includes a T-shaped wrench and a bracket cover fixed to each other, the bracket cover is fixedly sleeved on the rotating shaft, the upper end of the T-shaped wrench is provided with a mounting slot, the mounting slot is provided with a control module electrically connected to each other and a display screen located above the control module, the control module is connected to the pressure sensors respectively provided in the three gear slots, and the pressure sensors form abutment with the elastic top position assembly. Through the pressure signals fed back by the pressure sensors on different gear slots, the control module can directly analyze which gear slot the top position piece is in, and then display the result on the display screen, so that the user can directly and clearly observe which gear state the product is in.

[0008] Preferably, the nozzle unit comprises an arc-shaped outer tube, a baffle, and an arc-shaped inner tube. The arc-shaped outer tube is provided with an arc-shaped cavity that forms a sliding fit with the arc-shaped inner tube, and the bottom of the arc-shaped cavity is provided with a through hole that sleeves the arc-shaped inner tube; the front end of the arc-shaped inner tube is provided with a water inlet, the front end of the water inlet is provided with an outer ring that radially protrudes outward, and the outer ring is provided with two symmetrical hooks, the baffle is provided with and has only two openings that form a clearance limit fit with the hooks, the baffle forms a piston fit with the arc-shaped cavity, the baffle is provided with a first plug that cooperates with the water inlet, the baffle and the first step provided in the arc-shaped cavity form a limit abutment fit, the outer sleeve of the arc-shaped inner tube is provided with a return spring, the rear end of the return spring forms abutment fit with the bottom of the arc-shaped cavity, the return spring forms abutment fit with the arc-shaped inner tube, and the rear end of the arc-shaped inner tube is provided with a radial water outlet. 1. By setting one or more nozzle units, multiple different positions can be cleaned. 2. When water enters the water inlet, the water will directly impact the back of the baffle, the first plug will block the water inlet, the baffle will drive the entire arc inner tube to slide downward, and then the baffle will lean against the first step, the liquid will continue to enter from the gap between the hook and the baffle, the liquid will push the arc inner tube to continue to move downward, the lower end of the arc inner tube will pass through the through hole, and the water outlet will be exposed. At this time, the liquid will spray out from the water outlet along the arc inner tube, so as to clean the private parts conveniently and quickly. 3. The baffle has only two symmetrical openings, so that the contact area between the water flow and the baffle is large, thereby significantly improving the sealing of the baffle, so that the baffle has a stronger force on the arc inner tube, thereby shortening the reaction time of the arc inner tube without reducing the service life of the product. If the elastic force of the reset spring is reduced, the reaction time of the arc inner tube can also be shortened, but the reduction of the elastic force of the reset spring will seriously affect the service life of this product. Once the reset spring ages, the elastic force will be further reduced, which will cause the arc inner tube to move downward, causing the water outlet to leak. 4. The overall structure of this product is an arc-shaped structure. When the water flows into the arc-shaped inner tube, it will continuously impact the inner wall of the arc-shaped inner tube, thereby alleviating the instantaneous impact force of the water flow, so that the flow rate of the water flowing out of the outlet remains in a stable state. If this product is a straight tube structure, the water flow will not be eased layer by layer. At this time, the water flow sprayed from the outlet may be fast or slow because it has not been eased, resulting in insufficient stability; when the water inlet stops flowing, the water flow remaining in the arc-shaped cavity will continue to impact the inner wall of the arc-shaped inner tube according to inertia, delaying the contraction of the arc-shaped inner tube and avoiding excessive water stains in the arc-shaped inner tube.

[0009] Preferably, a radially protruding inner ring is provided near the outer ring on the outer surface of the arc-shaped inner tube, the inner side of the inner ring forms abutment with the reset spring, a first elastic sealing ring is provided between the inner ring and the outer ring, the outer diameter of the first elastic sealing ring is smaller than the baffle, the first elastic sealing ring forms a sealing abutment with the second step provided in the arc-shaped cavity, and the second step is located below the first step. The cross section of the first elastic sealing ring is an L-shaped structure, which includes an axially extending cylinder and a radially inwardly extending ring, the cylinder and the ring are an integrated structure, the ring is plugged and fixed between the inner ring and the outer ring, the cylinder is sleeved with the inner ring and the reset spring, the axial length of the cylinder is greater than the thickness of the inner ring, the arc-shaped inner tube is provided with a shrinkage tube portion fixedly sleeved on the inner wall of the arc-shaped inner tube near the water outlet, the shrinkage tube portion is provided with a third step at one end corresponding to the water inlet, the shrinkage tube portion is provided with an inner shrinkage hole, and the diameter of the inner shrinkage hole is smaller than the diameter of the arc-shaped inner tube. First, when the baffle is pressed against the first step and the arc-shaped inner tube continues to move downward, the first elastic sealing ring is sealed against the second step structure. At this time, the first elastic sealing ring improves the sealing between the arc-shaped inner tube and the arc-shaped cavity, avoiding water leakage and also avoiding water direct contact with the reset spring; second, the first elastic sealing ring is sleeved with the reset spring, which has a restraining force on the reset spring, effectively avoiding the displacement and dislocation of the reset spring due to aging; third, the axial length of the cylinder is greater than the thickness of the inner ring, so that the first elastic sealing ring is directly sealed against the second step structure, and the first elastic sealing ring itself has a good elastic buffering effect, thereby effectively improving the service life of the product and avoiding the noise generated by the inner ring contacting the arc-shaped cavity. When the water flow impacts, the water flow will directly impact the third step, thereby driving the arc-shaped inner tube to move downward, increasing the force of the water flow on the arc-shaped inner tube, so that the arc-shaped inner tube can directly overcome the force of the reset spring and move downward quickly, thereby improving the reaction efficiency of the arc-shaped inner tube.

[0010] Preferably, the arc-shaped outer tube is provided with an end cap at one end corresponding to the water inlet of the arc-shaped inner tube, the end cap and the arc-shaped outer tube form a sealed engagement, the end cap is provided with a water inlet pipe connected to the outside, the outer side of the end cap is provided with a water filter, the water filter is connected to the water inlet pipe and the water inlet respectively, and is used to filter the water flow at the water inlet pipe to prevent the water flow from clogging the arc-shaped inner tube, one side of the arc-shaped outer tube is provided with a convex rail extending along the main line of the arc-shaped outer tube, and the other side of the arc-shaped outer tube is provided with a track groove that is detachably engaged and fixed with the convex rail of the adjacent arc-shaped outer tube. The nozzle unit can be used alone, or the corresponding number of arc-shaped nozzles can be assembled by mutually engaging and fixing the arc-shaped outer tubes of different nozzle units, so it has better flexibility and can adapt to more practical needs. Different nozzle units can be used for different cleaning parts.

[0011] Preferably, the pressure reducing control device comprises a liquid flow channel, a control center, and a control valve, a pressure reducing valve, and an anti-backflow device which are sequentially installed in the liquid flow channel, the control center is connected to the control valve and the main control board box, the anti-backflow device comprises a second outer shell, an air inlet pipe, a liquid outlet pipe, and an anti-backflow core, the second outer shell is provided with a liquid outlet cavity whose bottom is connected to the liquid flow channel, the air inlet pipe is connected to the upper end of the liquid outlet cavity, the air inlet pipe is connected to the outside, the liquid outlet pipe is connected to the side of the liquid outlet cavity, the anti-backflow core is slidably installed in the liquid outlet cavity, the anti-backflow core can slide up and down along the liquid outlet cavity, the upper and lower ends of the anti-backflow core are respectively provided with second plugs corresponding to the air inlet pipe and the liquid flow channel, the anti-backflow core package The invention comprises a core body respectively connected to two second plugs, the core body comprises two integral disk parts and a cross plate part located in the middle of the two disk parts, the two disk parts respectively connect to two second plugs, the cross plate part is composed of two integral vertically crossed vertical plates, the second plug comprises a fixing ring and a second elastic sealing ring, the fixing ring is connected to the fixedly connected disk part, a plurality of guide rods extending outward are provided at the outer end of the fixing ring, a plurality of guide rods are circumferentially distributed at the upper end of the fixing ring to form a guiding part, the guiding part is plugged into and matched with a liquid flow channel or an air intake pipe, the second elastic sealing ring is fixedly installed between the disk part and the fixing ring, and the second elastic sealing ring is adapted to the liquid flow channel or the air intake pipe. During normal water discharge, the liquid flows along the liquid flow channel in sequence through the control valve, the pressure reducing valve, and enters the liquid outlet cavity. At this time, the liquid presses against the second plug at the lower end of the anti-backflow core, so the anti-backflow core moves up along the liquid outlet cavity to block the air inlet pipe opening; in the anti-backflow state, the liquid flow channel does not discharge water at this time, and the bottom of the anti-backflow core does not have the upward force of the liquid, so the anti-backflow core moves down due to gravity, and the external gas enters from the air inlet pipe, thereby destroying the vacuum environment in the liquid outlet cavity. The anti-backflow core continues to move down due to gravity to block the bottom water inlet of the liquid outlet cavity. In this environment, even if some liquid refluxes in the liquid outlet pipe, it will gather in the liquid outlet cavity and will not reflux along the liquid flow channel to the pressure reducing valve or the control valve. In the case of the vacuum destruction of the liquid outlet cavity, a large amount of liquid reflux will not occur, but even if a large amount of liquid reflux occurs due to abnormal reasons, the liquid can be discharged through the air inlet pipe without corresponding backflow.

[0012] Preferably, the control valve is an electromagnetic control valve, the liquid flow channel is provided with a valve cavity, the valve cavity includes a water outlet at the bottom and a water inlet at the side, the control valve includes a valve core, a valve bonnet, a second spring, and a thrust device, the valve core and the valve cavity form a sliding fit, the valve core and the water outlet form a piston fit, the upper end of the valve core and the groove provided in the valve bonnet form a limiting fit, the valve bonnet is limitedly installed in a slide groove provided on the top wall of the valve cavity, the valve bonnet is covered with a second spring, the upper end of the second spring is connected to the top wall of the valve cavity, the lower end of the second spring is connected to the valve core, the thrust device is connected to the upper end of the valve bonnet, and is used to push the valve bonnet to move up and down; the thrust device is connected to the control center, which includes a shell body, a thrust cylinder, and a piston assembly, the piston assembly and the piston cavity provided in the shell body form a sealed piston fit, the thrust cylinder is connected to the control center, the thrust cylinder is connected to the piston assembly, and is used to push the piston assembly to move up and down in the piston cavity, and the piston assembly and the raised portion provided on the upper end of the valve bonnet form abutment fit. The piston assembly is directly connected to the raised portion instead of the upper end surface of the valve cap, which can effectively avoid the wear of the valve cap by the piston assembly. When the thrust device pushes the valve cap downward, the valve core is limited to the bottom of the valve cavity, the liquid flow channel is closed, and the second spring mainly generates a downward elastic force on the valve core.

[0013] Preferably, a center groove is provided in the middle of the two fixing rings, and a first pressure sensor is provided in each of the two center grooves, and the first pressure sensor is connected to the control center. The valve core and the valve bonnet are respectively provided with a first center hole and a second center hole, and the valve core is sleeved with a first sealing ring. The valve core and the valve bonnet form a sealing piston fit, and the first center hole, the second center hole, and the piston cavity are connected in sequence. The piston assembly includes a piston rod, a piston head, and a second pressure sensor installed on the side of the piston head. One end of the piston rod is connected to the piston head and the other end is connected to the thrust cylinder, and the second pressure sensor is connected to the control center. In the circulation state, the second pressure sensor can monitor the hydraulic pressure of the water flow in real time. When the second pressure sensor detects that the hydraulic pressure of the water flow is too large, the control center can control the closure of the liquid flow channel to prevent excessive liquid flow from causing damage to the equipment.

[0014] Beneficial effect: the user drives the ceramic movable plate to rotate relative to the ceramic fixed plate by turning the knob of the manual water distributor, so that the manual water distributor has three states: the first state: the first water inlet pipe and the first water outlet pipe are isolated, and the second water inlet pipe and the two second water outlet pipes are isolated; the second state: turn the knob to make the ceramic movable plate rotate relative to the ceramic fixed plate, and the liquid water in the water tank flows into the first water inlet pipe through the pressure reducing control device, and the first water inlet pipe is connected to the first water outlet pipe through the first arc hole, the first arc groove, and the first water outlet, and the liquid water enters the heater through the first water outlet pipe, and the hot water heated by the heater flows into the second water inlet pipe, and the second water inlet pipe is connected to one of the second water outlet pipes through the second arc hole, the second arc groove, and one of the second water outlets, and the second water outlet pipe sprays out through the corresponding nozzle unit to clean the corresponding private part; the third state: the process is the same as the second state, the difference is that it sprays out from another second water outlet pipe, and the second water outlet pipe sprays out through the corresponding nozzle unit to clean another corresponding part.

When water enters the water inlet 36, the water will directly impact the back of the baffle 33, and the first plug 40 will block the water inlet 36. The baffle 33 will drive the entire arc-shaped inner tube 34 to slide downward, and then the baffle 33 will lean against the first step 41. The liquid will continue to enter from the gap between the hook 38 and the baffle 33, and the liquid will push the arc-shaped inner tube 34 to continue to move downward. The lower end of the arc-shaped inner tube 34 passes through the through hole, and the water outlet is exposed to the outside. At this time, the liquid will be sprayed out from the water outlet along the arc-shaped inner tube 34, so as to clean the private parts conveniently and quickly. 3. The baffle 33 has only two symmetrical openings 39, so that the contact area between the water flow and the baffle 33 is larger, thereby significantly improving the sealing of the baffle 33, so that the baffle 33 has a stronger force on the arc-shaped inner tube 34, thereby shortening the reaction time of the arc-shaped inner tube 34 without reducing the service life of the product. If the elastic force of the return spring 42 is reduced, the reaction time of the arc inner tube 34 can also be shortened. However, the reduction of the elastic force of the return spring 42 will seriously affect the service life of this product. Once the return spring 42 ages, the elastic force will be further reduced, which will cause the arc inner tube 34 to move downward, causing the water outlet to leak. 4. This product is an arc-shaped structure as a whole. When the water flows into the arc inner tube 34, it will continuously impact the inner wall of the arc inner tube 34, thereby alleviating the instantaneous impact force of the water flow, so that the flow rate of the water flowing out of the water outlet remains in a stable state. If this product is a straight tube structure, the water flow will not be eased layer by layer. At this time, the water flow sprayed from the water outlet may be fast and slow due to the lack of ease, resulting in insufficient stability; when the water inlet 36 stops inletting water, the water flow remaining in the arc cavity 35 continues to impact the inner wall of the arc inner tube 34 according to inertia, delaying the contraction of the arc inner tube 34, and avoiding excessive water stains in the arc inner tube 34.

First, when the baffle 33 rests on the first step 41 and the arc-shaped inner tube 34 continues to move downward, the first elastic sealing ring 44 seals against the second step 45. At this time, the first elastic sealing ring 44 improves the sealing between the arc-shaped inner tube 34 and the arc-shaped cavity 35, avoiding water leakage and also avoiding water directly contacting the reset spring 42; second, the first elastic sealing ring 44 is sleeved on the reset spring 42, which has a restraining force on the reset spring 42, effectively avoiding the displacement and dislocation of the reset spring 42 due to aging; third, the axial length of the barrel 441 is greater than the thickness of the inner ring 43, so that the first elastic sealing ring 44 directly seals against the second step 45, and the first elastic sealing ring 44 itself has a good elastic buffering effect, thereby effectively improving the service life of the product and avoiding the noise generated by the inner ring 43 contacting the arc-shaped cavity 35. When the water flow impacts, the water flow will directly impact the third step 47, thereby driving the arc-shaped inner tube 34 to move downward, increasing the force of the water flow on the arc-shaped inner tube 34, so that the arc-shaped inner tube 34 can directly overcome the force of the return spring 42 and move downward quickly, thereby improving the reaction efficiency of the arc-shaped inner tube 34.

During normal water discharge, the liquid flows along the liquid flow channel 51 in sequence through the control valve 52, the pressure reducing valve 53, and into the liquid outlet cavity 59. At this time, the liquid presses on the second plug 60 at the lower end of the anti-backflow core 58, so the anti-backflow core 58 moves up along the liquid outlet cavity 59 to block the air inlet pipe 56; in the anti-backflow state, the liquid flow channel 51 does not discharge water, and the bottom of the anti-backflow core 58 does not have the upward force of the liquid. Therefore, the anti-backflow core 58 moves downward due to gravity, and external gas enters from the air inlet pipe 56, thereby destroying the vacuum environment in the liquid outlet cavity 59. The anti-backflow core 58 continues to move downward due to gravity to block the bottom water inlet 36 of the liquid outlet cavity 59. In this environment, even if some liquid refluxes from the liquid outlet pipe 57, it will gather in the liquid outlet cavity 59 and will not flow back along the liquid flow channel 51 to the pressure reducing valve 53 or the control valve 52. When the vacuum of the liquid outlet cavity 59 is destroyed, a large amount of liquid will not flow back. However, even if a large amount of liquid flows back due to abnormal reasons, the liquid can be discharged through the air inlet pipe 56 without corresponding backflow.
