Description

Technical Field

[0001] The utility model relates to the technical field of bathroom product production, in particular to a switchable water outlet valve for an intelligent toilet. Background Art

[0002] At present, the water tank of the smart toilet generally adopts a low water tank method, which makes the overall aesthetics better. However, the problem brought by the low water tank method is that the flushing potential energy is insufficient. Therefore, it is generally necessary to use a water pump to pump the water in the water tank to the brush ring waterway, the main flushing waterway, etc. in sequence, and use the position change of the float in the water tank to switch and control the water flow to the brush ring waterway or the main flushing waterway. That is, when the water level is at the original position or high position, the brush ring waterway is flushed first, and then the water in the water tank is continuously pumped out. When the water level drops, the position of the float also drops. When it reaches a certain lower water level, the lever-type switching structure is used to open the main flushing waterway and close the brush ring waterway.

[0003] Although the above method realizes the switching water discharge and the structure has a certain stability, it still has some shortcomings: (1) The volume is too large; the entire water outlet valve includes a float and a main body with a water outlet pump, which causes a large space to be occupied in the water tank, thereby reducing the water storage space of the water tank, and it is easy for a tank of water to not be completely flushed clean; (2) The switching part is linked with the float; the overall volume of the float must be large enough, otherwise it cannot drive the lever to switch, and there will be a situation where the switching response is slow and the switching is delayed, and the volume of the float cannot be reduced; more importantly, the function of the float itself for water intake is restricted, and it is impossible to achieve flushing and replenishing the water tank at the same time; (3) The movement of the float needs to be restricted, and it cannot swing too much as the water level changes, otherwise it will affect the switching;

[0004] In summary, the existing switchable water outlet valve structure needs to be further improved. Utility Model Content

[0013] Furthermore, the pressure-bearing cover is driven by water pressure to move along the axial direction of the shell, and the pressure-bearing cover is driven to spirally drop and stop in the lower pressure-releasing state through the cooperation of the connecting piece and the guide column.

[0014] Furthermore, the guide column is formed with at least two inclined parts, and the guide rails are arranged around the inclined parts; wherein, the connecting member moves along the guide rails and runs along the inclined parts to each of the parking positions in a pressure-released state.

[0033] See also Figure 1-4 The switchable water outlet valve for an intelligent toilet described in this embodiment is installed in the water tank of the intelligent toilet and is used to switch the water in the water tank between the brush ring water channel and the main flushing water channel to flush away waste.

[0034] The water outlet valve described in this embodiment includes: a housing 1, a water pumping member (not shown in the figure) and a switching group 2;

[0035] The shell 1 is injection molded and has a water inlet 11, a pressure chamber 12 and two water outlets 13 and 14 respectively connected to the brush ring water channel and the main flushing water channel; it should be noted that the shell 1 is installed in the water tank, and the two water outlets 13 and 14 are respectively installed through hoses or directly corresponding to the brush ring water channel and the main flushing water channel; in this embodiment, the two water outlets 13 and 14 are respectively located at the top and side of the pressure chamber 12; the connecting parts 211 and 212 on the pressure sealing cover 21 are opened on the top and side corresponding to the two water outlets 13 and 14, so that water distribution is simpler and more stable.

[0036] The pumping component is installed at the water inlet part 11, and the control component is used to control the pumping component to power on and pump water or to power off and stop water supply; the pumping component in this embodiment is illustrated by a water pump, which is installed at the bottom of the water tank and is used to pump water in the water tank to the water inlet part 11 to supply water to the brush circle water channel and the main flushing water channel for flushing.

[0037] The switching group 2 includes a pressure-bearing cover 21, a connector 22, and a guide post 23. The pressure-bearing cover 21 moves within the pressure-bearing chamber 12 under the action of water pressure and is provided with connecting portions 211 and 212. The pressure-bearing cover 21 is provided with at least two connecting portions 211 and 212, i.e., the two connecting portions 211 and 212 correspond to the two water outlets 13 and 14 of the brush ring water channel and the main flushing water channel on the housing 1, respectively.

[0038] The outer wall of the guide column 23 is formed with a guide rail 231 and at least two parking positions 232, 233 located on the guide rail 231; the parking positions 232, 233 here refer to the positions where the pressure-bearing cover 21 stops after vertical displacement and circumferential rotation; the guide column 23 is formed with at least two inclined portions 234, 235, and the guide rail 231 is arranged around the inclined portions 234, 235; wherein, the connecting member 22 moves along the guide rail 231 and moves along the inclined portions 234, 235 to stop at the parking positions 232, 233 in the pressure-release state, thereby ensuring that the connecting member 22 can rotate circumferentially during use and return to its original position when the power is turned on and used again after a sudden power failure.

[0039] One end of the connecting member 22 is connected to the pressure-bearing cover 21, and the other end is placed in the guide rail 231; the connecting member 22 is configured as a pin or a ball, and a pin 22A is used as an example in this embodiment; wherein, the pressure-bearing cover 21 is pressurized or released by the water flow, and the connecting member 22 connected thereto moves axially and circumferentially along the guide rail 231, and when it falls at the parking position 232, 233, the connecting parts 211, 212 of the pressure-bearing cover 21 correspond to the brush ring water channel or the main flushing water channel.

[0040] It also includes two water outlet pipes, which are respectively arranged corresponding to the two water outlet parts 13 and 14 and are connected; the water outlet direction of the water outlet pipe 6 connected to the top is perpendicular to the axis of the shell 1, and the water outlet direction of the water outlet pipe connected to the side is arranged at an acute angle to the axis of the shell 1.

[0041] The pressure-bearing sealing cover 21 is driven by water pressure to move axially along the shell 1, and the pressure-bearing sealing cover 21 is driven to spirally drop and stop in the lower pressure-releasing state through the cooperation of the connecting piece 22 and the guide column 23.

[0042] To facilitate molding and assembly, the shell 1 includes an outer shell 1A and a base 1B, and the outer shell 1A and the base 1B are sealed together to form a pressure-bearing chamber 12; the base 1B is formed with the water inlet part 11 and the fixing part 15 for attaching the guide column 23; the fixing part 15 is formed with an inclined surface 236 for guiding the connecting part 22 to return to the original parking position 232.

[0043] In order to ensure the stability of the entire structure and the reliability of the reset, an elastic member 4 can be added, which is arranged between the inner top surface of the pressure-bearing chamber 12 and the outer top surface of the pressure-bearing cover 21 to drive the pressure-bearing cover 21 to reset in the pressure-release state;

[0044] More specifically, it also includes a water inlet pipe 5, which is detachably mounted on the shell 1; the water inlet pipe 5 includes an outer tube body 51 and an inner tube body 52, the water inlet end of the inner tube body 52 is connected to the pumping member, and the water outlet end is axially higher than the two water outlet parts 13 and 14 of the shell 1, and is connected to the outer tube body 51, and the outer tube body 51 is connected to the water inlet part 11 of the shell 1; such a setting ensures that the water in the water tank can be replenished to a high position, and the water tank will not be unable to be filled with water. If the position of the water inlet pipe 5 is lower than the water outlet parts 13 and 14, the water tank will directly enter the pressure chamber 12 as soon as it is replenished. By designing the outer tube body 51 and the inner tube body 52 in this way, this situation is prevented from happening.

[0045] During actual assembly and use,

[0046] (1) The guide column 23 is installed at the center of the corresponding pressure-bearing cover 21 and a pin 22A is inserted inward from the outer wall of the pressure-bearing cover 21, wherein one end (outer end) of the pin 22A is attached to the pressure-bearing cover 21 and the other end (inner end) is placed on the guide rail 231 of the guide column 23, so that the pressure-bearing cover 21 can move along the track of the guide rail 231 through the pin 22A, that is, it can move up and down and can rotate a certain angle along the circumference of the guide column 23;

[0047] (2) The guide column 23 and the pressure-bearing cover 21 are mounted on the fixed portion of the base 1B, and the guide column 23 and the base 1B are assembled so as to be non-rotatable, that is, a cross column is formed at the position where the guide column 23 and the base 1B meet, thereby ensuring that the guide column 23 is fixed and cannot rotate; in addition, inclined portions 234 and 235 are formed at the fixed portion for guiding the pin 22A to return to the original parking position 232 and 233, that is, a complete running track is constructed by the guide column 23 and the inclined portions 234 and 235 on the base 1B;

[0048] (3) The housing 1A and the base 1B are sealed and assembled together by means of screws, snaps, or other connection methods to form a complete pressure-bearing cavity 12, so that the pressure-bearing cover 21 can move within the pressure-bearing cavity 12;

[0049] (4) Assemble the water inlet pipe 5, place the sealing sleeve of the outer tube body 51 on the outer periphery of the inner tube body 52, and make the water outlet position of the inner tube body 52 located inside the outer tube body 51, forming an n-shaped water passage inside the outer tube body 51, and the water outlet of the outer tube body 51 and the water inlet part 11 of the outer shell 1A are quickly assembled through the C-shaped clamping ring 7, and the water inlet of the inner tube body 52 is connected to the water pump inside the water tank.

[0050] When using,

[0051] (1) Figure 5 As shown, when the water pump is turned on, water flows upward from the inner tube body 52, then flows downward from the water passage between the inner tube body 52 and the outer tube body 51 into the water inlet portion 11 of the housing 1, and then enters the pressure chamber 12;

[0052] (2) After water enters the pressure-bearing chamber 12, the water flow gradually fills the pressure-bearing chamber 12, and the water pressure impacts the pressure-bearing cover 21, causing it to move upward along the guide rail 231 of the guide column 23 (that is, point A of the guide rail 231 moves upward to 232). At this time, the connecting portion 211 on the top surface of the pressure-bearing cover 21 is connected with the water outlet portion 13 at the top of the pressure-bearing chamber 12 (that is, the water outlet portion 13 of the brush ring water channel), and the water flows out from here. At the same time, the connecting portion 212 on the side of the pressure-bearing cover 21 and the water outlet portion 14 on the side of the shell 1 (that is, the water outlet portion 14 of the main flushing channel) are in a dislocated state, and then in a closed state, so as to realize the separate flushing of the brush ring water channel;

[0053] (3) Figure 6As shown, after a certain flushing time is set by the controller, the water pump is turned off. At this time, the water pump does not work, and the pressure-bearing cover 21 is no longer impacted by the water flow and falls back. During the falling process, the pin 22A moves along the motion trajectory of the guide rail 231 (that is, point 232 of the guide rail 231 moves downward to the inclined portion 235), thereby driving the pressure-bearing cover 21 to rotate a certain angle during the falling process; at this time, the connecting portion 211 on the top surface of the pressure-bearing cover 21 is misaligned with the water outlet 13 at the top of the pressure-bearing chamber 12 (that is, the water outlet 13 of the brush ring water channel), and the connecting portion 212 on the side corresponds to the water outlet 14 on the side of the shell 1 (that is, the water outlet 14 of the main flushing channel);

[0054] (4) The controller turns on the water pump again, and water flows into the pressure chamber 12 again. At this time, the pressure cover 21 moves upward again (i.e., the pin 22 of the guide rail 231 moves upward, from the inclined portion 235 to the parking position 233), and is held against the inner top surface of the pressure chamber 12. However, due to the misalignment of the water outlet 13 on the top surface, the water flows out only from the side water outlet 14, thereby realizing the flushing of the main flushing channel. After flushing for a certain period of time, the water pump is turned off again;

[0055] (5) The water flow from the water inlet pipe 5 and the pressure chamber 12 is gradually discharged into the toilet to form a water seal (i.e., water seal replenishment is achieved);

[0056] (6) The pressure-bearing cover 21 falls back again due to the lack of water pressure impact. At this time, the pressure-bearing cover 21 is reset to its original position through the inclined surface 236. Even if there is a sudden power outage during use, the pressure-bearing cover 21 can be returned to its original position through the inclined surface 236, avoiding the main flushing channel from flowing out when it is opened next time, which affects the user experience.

[0057] The utility model provides a switching water outlet valve for an intelligent toilet, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problem that the switching water outlet valve used in the existing intelligent toilet can only be switched by the height of the float bucket, the entire water outlet valve is large in size, and it is difficult to achieve water replenishment at the same time as flushing; the utility model breaks the limitation of switching by the float bucket used for water replenishment in the water tank in conjunction with the lever structure, reduces the volume of the switching structure, and uses the impact force of the water pressure to intermittently push the pressure-bearing cover to achieve sequential brush ring flushing and main flushing, that is, after the water flow lifts the pressure-bearing cover, it is first flushed from the water outlet part of the main flushing channel, and after the pumping part is paused, the pressure-bearing cover falls and is guided by the connecting part and the guide rail. With the cooperation of the pumping part, the pressure-bearing cover is rotated to a certain angle; when the pumping part is opened again to let water in, the water flows from the other connecting part of the pressure-bearing cover to the water outlet to form the main flushing; this method can not only reduce the volume (that is, the volume of the switching water outlet valve and the float bucket can be reduced, thus reducing the space occupied by the water tank and increasing the water storage capacity of the water tank), but also is not associated with the float bucket used to replenish water in the water tank. During the switching water outlet process, the float bucket can be replenished without reaching the lowest water level, so that there is sufficient water in the water tank for flushing; more importantly, even if the power is cut off during use, the switching group of this new type can still be reset, and flushing will be carried out from the brush circle waterway when it is opened again to avoid the occurrence of accidental flushing.

[0058] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation on the protection scope of the present utility model.
