Description

Technical Field

[0001] This application relates to the field of smart bathroom technology, and more particularly to a water spray mechanism and a smart toilet. Background Technology

[0002] Currently, the variable water spray function of smart toilets on the market is mainly achieved by designing a sliding component inside the nozzle that connects to a motor outside the nozzle. The motor directly drives the sliding component to slide back and forth, thereby changing the water outlet cross section of the nozzle.

[0003] However, the solution of directly driving the sliding parts with a motor usually has the following disadvantages: during the process of the motor driving the sliding parts, it is not possible to respond quickly, and it takes a certain amount of time to switch the water spray. Moreover, due to the use of a stepper motor, it is not possible to switch at high speed; the motor occupies a large space inside the spray bar, making the internal space cramped and affecting the pipeline layout. Summary of the Invention

[0004] The water spray mechanism and smart toilet provided in this application can solve the problems in the prior art where the change of the water outlet cross section of the nozzle of the water spray mechanism needs to be achieved by the motor directly driving the sliding part to slide back and forth, which makes it impossible to respond quickly, requires a certain amount of time to switch the water spray, and cannot switch at high speed due to the use of a stepper motor, and the motor occupies a large space inside the spray bar, making the internal space cramped and affecting the pipeline layout.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a water spraying mechanism, wherein the water spraying mechanism includes: a housing with an internal cavity, a first water inlet pipe and a first water outlet pipe respectively provided on the adjacent first and second sides of the housing, the cavity connecting the first water inlet pipe and the first water outlet pipe; a rotating member disposed in the cavity, the rotating member having an acute angle between the third side of the rotating member facing the first water outlet pipe and a set direction; the set direction being parallel to the central axis of the first water outlet pipe; a push rod, one end of the push rod abutting against the third side of the rotating member, the other end of which extends along the set direction, so that when the rotating member rotates around the set direction, the third side of the rotating member will drive the push rod to extend into the first water outlet pipe and move back and forth along the set direction; wherein the central axis of the push rod coincides with the central axis of the first water outlet pipe, and the push rod is spaced apart from the inner wall of the first water outlet pipe.

[0006] The shell also has a sliding groove and a first water flow channel formed inside. The sliding groove connects the receiving cavity with the first water outlet pipe, and the first water flow channel connects the receiving cavity with the first water outlet pipe. The other end of the push rod is embedded in the sliding groove.

[0007] Among them, a stop block is also provided on the side wall of the push rod in the vertical setting direction, and the stop block abuts against the inner side wall of the sliding groove.

[0008] The rotating component includes a control part and a connecting part connected to each other. The control part includes a first sidewall and a second sidewall. The first sidewall is partially cylindrical. The second sidewall is connected to the opening at one end of the first sidewall. The angle between the second sidewall and the set direction is an acute angle. One end of the push rod passes through the opening at the other end of the first sidewall and abuts against the second sidewall. One end of the connecting part is connected to the middle position of the side of the second sidewall opposite to the push rod, and the other end extends in the opposite direction of the set direction.

[0009] The water spraying mechanism also includes a bottom cover and a connecting shaft. The bottom cover is connected to the fourth side of the housing to close the accommodating cavity. The bottom cover is provided with a limiting hole. The connecting part is provided with a mounting hole corresponding to the limiting hole. The two ends of the connecting shaft are respectively embedded in the mounting hole and the limiting hole. An impeller is also provided on the side wall of the connecting part in the parallel setting direction. The fourth side of the housing and its second side are opposite sides.

[0010] The bottom cover has a limiting notch at its edge, and the fourth side of the shell has a limiting step corresponding to the limiting notch. The limiting step is embedded in the limiting notch.

[0011] The water spraying mechanism also includes a drive shaft. The other end of the connecting part away from the push rod is connected to one end of the drive shaft, and the other end of the drive shaft is connected to an external drive mechanism.

[0012] The push rod abuts against the third side of the rotating part, which is arc-shaped.

[0013] The shell has a second water inlet pipe on its first side, spaced apart from the first water inlet pipe, and a second water outlet pipe on its second side, spaced apart from the first water outlet pipe. A second water flow channel is also formed inside the shell, which connects the second water inlet pipe and the second water outlet pipe.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide an intelligent toilet, wherein the intelligent toilet includes: a water spraying mechanism and a water storage mechanism, the water spraying mechanism includes a first water inlet pipe, the first water inlet pipe being connected to the water storage mechanism; wherein the water spraying mechanism is the water spraying mechanism as described in any of the preceding claims.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, the water spraying mechanism provided in this application has a receiving cavity inside its housing. A first inlet pipe and a first outlet pipe are respectively provided on the adjacent first and second sides of the housing. A rotating component is disposed within this receiving cavity. The angle between the third side of the rotating component facing the first outlet pipe and the set direction is an acute angle; that is, the third side of the rotating component is specifically an inclined plane relative to the opening of the first outlet pipe. One end of the push rod abuts against the third side of the rotating component, and its other end extends along the set direction to allow the rotating component to rotate around the set direction. During rotation, the distance between the area on the third side of the rotating component corresponding to the push rod and the opening of the first water outlet pipe changes continuously with the rotation. This allows the push rod to extend back and forth into the first water outlet pipe in a set direction, constantly adjusting the depth of the push rod's insertion into the first water outlet pipe. This enables the water to be introduced from the first water inlet pipe into the internal cavity of the housing and sprayed out from the first water outlet pipe, rapidly changing the water outlet cross-section to generate different water spray patterns. Furthermore, the periodic back-and-forth movement of the push rod driven by the uniformly rotating component also creates a pulse effect. Moreover, compared to directly driving the push rod with a separate power unit, using the rotating component to drive the push rod obviously simplifies the overall structure of the water spray mechanism, makes it easier to install, and reduces implementation costs.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please see Figures 1-3 ,in, Figure 1 This is an exploded schematic diagram of one embodiment of the water spraying mechanism of this application. Figure 2 yes Figure 1 Assembly diagram of the central water jet mechanism. Figure 3 yes Figure 2 A cross-sectional view of the water spray mechanism in operation. In this embodiment, the water spray mechanism 1 includes: a housing 10, a rotating component 20, and a push rod 30.

[0034] Specifically, the water spray mechanism 1 provided in this application can be applied to a smart toilet to draw water from the water storage mechanism of the smart toilet and spray it out in a directional manner to clean specific parts of the user's body. Of course, in other embodiments, the water spray mechanism 1 can also be used in any other reasonable mechanical device such as a toy water gun or a sprayer, and this embodiment does not limit it in this way.

[0035] Specifically, the housing 10 of the water spraying mechanism 1 has a cavity 111 inside, which serves as a water flow channel inside the water spraying mechanism 1. A first water inlet pipe 11 is also provided on the first side of the housing 10, and a first water outlet pipe 12 is also provided on the second side of the housing 10 corresponding to the first water inlet pipe 11.

[0036] Furthermore, the first water inlet pipe 11 is connected to the first water outlet pipe 12 through the accommodating cavity 111, so that after the water flow from the external water channel or the external water storage mechanism is introduced into the accommodating cavity 111 inside the housing 10 through the first water inlet pipe 11, it can then be sprayed out from the pipe opening of the first water outlet pipe 12 to clean specific parts of the user.

[0037] It should be noted that the first side and the second side of the housing 10 are specifically adjacent sides, so as to facilitate the installation and layout of the water flow channel and corresponding components in the water spray mechanism 1.

[0038] Furthermore, the rotating component 20 of the water spray mechanism 1 is specifically disposed in the receiving cavity 111 of the housing 10, and as shown... Figure 4 As shown, Figure 4 yes Figure 3A detailed sectional view of the rotating component in the water spray mechanism shows that the angle σ between the third side of the rotating component 20 facing the first water outlet pipe 12 and the set direction Z is specifically an acute angle.

[0039] The set direction is parallel to the central axis of the first water outlet pipe 12, that is, the third side of the rotating member 20 is set at an angle relative to the opening of the first water outlet pipe 12.

[0040] Furthermore, one end of the push rod 30 of the water spraying mechanism 1 is in contact with the third side of the rotating member 20, while the other end extends along the set direction Z. When the rotating member 20 is driven by an external force to rotate around the set direction Z, the distance between the part of the third side of the rotating member 20 where the push rod 30 is located and the opening of the first water outlet pipe 12 will change continuously with the rotation. This allows the push rod 30 to be driven to extend into the first water outlet pipe 12 along the set direction and move back and forth, so as to continuously adjust the depth of the push rod 30 extending into the first water outlet pipe 12.

[0041] Specifically, the central axis of the push rod 30 coincides with the central axis of the first water outlet pipe 12, and the cross-sectional dimension of the push rod 30 is smaller than the inner diameter of the first water outlet pipe 12.

[0042] Understandably, after the push rod 30 is inserted into the first water outlet pipe 12, it will partially fill and block the first water outlet pipe 12. The depth to which the push rod 30 is inserted into the first water outlet pipe 12 will result in different degrees of blockage, and the water sprayed from the first water outlet pipe 12 will have different water outlet cross sections.

[0043] It is worth noting that by continuously adjusting the depth of the push rod 30 inserted into the first water outlet pipe 12, the water outlet cross-section of the first water outlet pipe 12 can be continuously adjusted accordingly. Figure 3 As shown, when the distance between the portion of the rotating component 20 corresponding to the area where the push rod 30 is located and the opening of the first water outlet pipe 12 is at its maximum, the push rod 30 will either not extend into the first water outlet pipe 12, or will extend into the first water outlet pipe 12 to its minimum depth. In this case, if... Figure 5 As shown, Figure 5 yes Figure 3 The schematic diagram of the water outlet section of the water spray mechanism in its current operating state shows that the water sprayed from the first water outlet pipe 12 will be cylindrical, and the water outlet section will be circular. At this time, the water output per unit time is the maximum.

[0044] Furthermore, such as Figure 6 and Figure 7 As shown, where, Figure 6 yes Figure 2 A cross-sectional view of the central water spray mechanism in another operating state. Figure 7 yes Figure 6 A schematic diagram of the water outlet cross section of the water spraying mechanism in its current operating state. When the distance between the part of the third side of the rotating component 20 where the push rod 30 is set and the opening of the first water outlet pipe 12 is at its minimum, the depth of the push rod 30 extending into the first water outlet pipe 12 will be at its maximum. At this time, the water sprayed from the first water outlet pipe 12 will be in the shape of a circular tube, and the water outlet cross section will be in the shape of a ring. At this time, the water output per unit time will be at its minimum.

[0045] Therefore, as the rotating component 20 rotates continuously around the set direction Z, the cross-section of the water sprayed from the first water outlet pipe 12 will periodically change from a circle to an annulus. The inner diameter of this annulus will gradually increase and then gradually decrease until it becomes a circle again, and then repeat the next cycle, thereby enabling the water outlet of the first water outlet pipe 12 to have a pulse effect.

[0046] It is worth noting that when the actual application scenario of the water spray mechanism 1 requires obtaining water spray of other shapes, it can be achieved by designing the push rod 30 with different shapes, cross-sectional dimensions, lengths, and the ability to extend into the first water outlet pipe 12 to different depths, or by adjusting the angle σ between the third side of the rotating member 20 facing the first water outlet pipe 12 and the set direction. This application does not limit this.

[0047] In the above scheme, as the rotating component 20 rotates around a set direction, the distance between the portion of the third side of the rotating component 20 corresponding to the push rod 30 and the opening of the first water outlet pipe 12 changes continuously. This causes the push rod 30 to extend back and forth into the first water outlet pipe 12 along the set direction, thereby continuously adjusting the depth of the push rod 30 into the first water outlet pipe 12. This allows external water to be introduced into the receiving cavity 111 inside the housing 10 through the first water inlet pipe 11 and sprayed out from the first water outlet pipe 12, rapidly changing the water outlet cross-section to generate different water sprays. Furthermore, the periodic back-and-forth movement of the push rod 30 driven by the uniformly rotating rotating component 20 also provides a pulse effect. Compared to directly driving the push rod 30 to perform the corresponding back-and-forth movement with a separate power device, using the rotating component 20 to drive the push rod 30 obviously simplifies the overall structure of the water spray mechanism 1, makes it easier to install, and reduces the implementation cost.

[0048] In one embodiment, the interior of the housing 10 is further provided with a sliding channel 112 and a first water flow channel 113 spaced apart. One end of the sliding channel 112 is specifically connected to the accommodating cavity 111 inside the housing 10, while the other end is connected to the first water outlet pipe 12. That is, the accommodating cavity 111 is specifically connected to the first water outlet pipe 12 through the sliding channel 112.

[0049] Furthermore, one end of the first water flow channel 113 corresponds to the accommodating cavity 111 inside the housing 10, while the other end is connected to the first water outlet pipe 12, so as to connect the accommodating cavity 111 and the first water outlet pipe 12 through the first water flow channel 113.

[0050] One end of the push rod 30 abuts against the third side of the rotating member 20, while the other end is embedded in the sliding groove 112, so that it can pass through the sliding groove 112 and extend into the first water outlet pipe 12 in the set direction Z to move back and forth. The sliding groove 112 provides a sliding channel and limiting support. The water in the accommodating cavity 111 of the housing 10 can enter the first water outlet pipe 12 through the bypass first water flow channel 113 and be sprayed out from the first water outlet pipe 12.

[0051] In one embodiment, a stop 31 is also provided on the side wall of the push rod 30 in the vertical setting direction, and the stop 31 abuts against the inner side wall of the sliding groove 112.

[0052] Understandably, the internal shape of the sliding groove 112 is specifically defined by the push rod 30 and the stop block 31, so that when the push rod 30 moves back and forth in the sliding groove 112, it can slide more stably with the help of the stop block 31.

[0053] In one embodiment, the first side of the housing 10 is provided with a second water inlet pipe 13 spaced apart from the first water inlet pipe 11, and the second side of the housing 10 is provided with a second water outlet pipe 14 spaced apart from the first water outlet pipe 12. The housing 10 also has a second water flow channel 131 inside, and the second water inlet pipe 13 is specifically connected to the second water outlet pipe 14 through the second water flow channel 131.

[0054] It is understood that the water spray channel formed by the second water inlet pipe 13, the second water flow channel 131 and the second water outlet pipe 14 is independent of and not connected to the water spray channel formed by the first water inlet pipe 11, the accommodating cavity 111 and the first water outlet pipe 12, so that water spray control can be performed independently and used to clean different parts of the user.

[0055] In other embodiments, the water spraying mechanism 1 may be further provided with another water spraying channel consisting of a third water inlet pipe 15, a third water flow channel 151 and a third water outlet pipe 16, or other more independent water spraying channels, which will not be described in detail here.

[0056] In one embodiment, an air intake groove 121 is also provided on the side wall of the first water outlet pipe 12 so that when the first water outlet pipe 12 sprays water outward, the air intake groove 121 can inject air into the water spray using the Venturi principle, thereby increasing the cleaning power.

[0057] It should be noted that the Venturi principle can be explained as follows: when wind blows over an obstruction, the air pressure near the upper port on the leeward side of the obstruction is relatively low, which creates an adsorption effect and causes airflow.

[0058] Please continue to refer to the following: Figure 8 and Figure 9 ,in, Figure 8 yes Figure 1 A detailed structural diagram of the first outer shell of the housing in the central water spray mechanism. Figure 9 yes Figure 1 A detailed structural diagram of the second outer shell of the housing in the central water spray mechanism.

[0059] In one embodiment, the housing 10 of the water spraying mechanism 1 may specifically include a first outer shell 101 and a second outer shell 102, and the first outer shell 101 and the second outer shell 102 can cover and connect with each other to form the accommodating cavity 111, sliding groove 112, first water flow channel 113, second water inlet pipe 13, second water flow channel 131, second water outlet pipe 14, third water inlet pipe 15, third water flow channel 151 and third water outlet pipe 16 inside the housing 10, etc., which will not be described in detail here.

[0060] Optionally, the second outer shell 102 may be detachably connected to the first outer shell 101 for easy disassembly and cleaning, or it may be fixedly connected to the first outer shell 101, for example, by ultrasonic welding. The second outer shell 102 and the first outer shell 11 may also be integrally formed components, which is not limited in this application.

[0061] Optionally, the first water inlet pipe 11, the second water inlet pipe 13, the third water inlet pipe 15, the first water outlet pipe 12, the second water outlet pipe 14, and the third water outlet pipe 16 can also be detachably connected to the outer walls of the first housing 101 and the second housing 102, so that they can be disassembled and cleaned after a period of use, thereby further reducing the possibility of water spray channel blockage.

[0062] Please continue reading. Figure 10 , Figure 10 yes Figure 1 A detailed structural diagram of an embodiment of the rotating component in the water spray mechanism.

[0063] In one embodiment, the rotating member 20 further includes a control part 21 and a connecting part 22 connected to each other, and the control part 21 further includes a first sidewall 211 and a second sidewall 212. The first sidewall 211 is specifically in the shape of a partially circular tube, and the second sidewall 212 is connected to the opening at one end of the first sidewall 211 to close the opening at one end of the first sidewall 211.

[0064] Furthermore, the angle σ between the second sidewall 212 and the set direction corresponds to an acute angle, and one end of the push rod 30 passes through the opening at the other end of the first sidewall 211 and abuts against the second sidewall 212.

[0065] In this component, one end of the connecting part 22 in the rotating component 20 is specifically connected to the middle position of the side of the second side wall 212 opposite to the push rod 30, while the other end extends in the opposite direction of the set direction Z, so that the rotating component 20 as a whole rotates around the central axis of the connecting part 22, thereby driving the push rod 30 to extend into the first water outlet pipe 12 and move back and forth in the set direction Z.

[0066] Furthermore, in one embodiment, the water spraying mechanism 1 further includes a bottom cover 40 and a connecting shaft 50, and the receiving cavity 111 inside the housing 10 forms an opening corresponding to the fourth side surface of the housing 10. The bottom cover 40 is specifically connected to the fourth side surface of the housing 10 to close the receiving cavity 111 of the housing 10. A limiting hole 401 is also provided on the bottom cover 40, and the connecting part 22 of the rotating member 20 is also provided with a mounting hole 2201 corresponding to the limiting hole 401. An impeller 23 is also provided on the side wall of the connecting part 22 in the parallel setting direction.

[0067] The fourth side of the housing 10 and its second side are opposite sides. The mounting hole 2201 in the connecting part 22 can be a blind hole, and the opposite ends of the connecting shaft 50 are respectively embedded in the mounting hole 2201 and the limiting hole 401.

[0068] In another embodiment, the mounting hole 2201 in the connecting part 22 can be a through hole, and the inner wall of the first outer shell 11 corresponding to the accommodating cavity 111 is also provided with a mating hole 114 corresponding to the mounting hole 2201. One end of the connecting shaft 50 is specifically embedded in the mating hole 114, while the other end passes through the mounting hole 2201 to be embedded in the limiting hole 401.

[0069] Understandably, by setting an impeller 23 in the rotating component 20, during the process of introducing water from the external water storage mechanism into the receiving cavity 111 of the housing 10 through the first water inlet pipe 11, the impeller 23 will be continuously impacted, thereby driving the connecting part 22 and the control part 21 of the rotating component 20 to rotate in the set direction Z, specifically around the central axis of the connecting part 22. This will drive the push rod 30 to extend into the first water outlet pipe 12 in the set direction Z and move back and forth, so that the water outlet cross section of the first water outlet pipe 12 will change periodically, producing different water splashes and a pulse effect.

[0070] Optionally, the length of the impeller 23 in the set direction Z is less than the length of the connecting part 22 in the set direction Z, and one end of the impeller 23 abuts against the second side wall 212 of the control part 21, while the other end is spaced apart from the bottom cover 40, so as to avoid the contact area between the impeller 23 and the bottom cover 40, thereby avoiding mutual friction between the impeller 23 and the bottom cover 40 during the rotation process, which would affect the rotation of the impeller 23.

[0071] Optionally, the impeller 23 includes a plurality of blades (not shown in the figure) of any reasonable number such as 4, 6 or 5, one end of the plurality of blades is uniformly connected to the side wall of the connecting part 22, and each blade is in the shape of an arc plate. This application does not limit this.

[0072] The above-described solution simplifies the overall structure of the water spray mechanism 1, which uses the inclined surface of the impeller 23 and control unit 21 to drive the push rod 30 to move back and forth in the first water outlet pipe 12 along the set direction Z. Utilizing water as a power source eliminates the need for other power devices, effectively improving the reliability of the mechanism's operation and reducing production costs. It also avoids vibration and noise that could negatively impact the user experience and does not adversely affect the overall structural layout of the machine. Furthermore, by effectively achieving a variable water spray and pulse effect, it helps increase the cleaning area and cleaning rate of the water spray mechanism 1, thereby reducing the need for high flow rates, achieving first-level water calibration, significantly improving the user's cleaning experience, and conserving water resources.

[0073] In addition, since the water spray mechanism 1 has a rotating part 20 inside, the risk of scale buildup inside the nozzle is reduced. This also avoids the need to install other power devices, such as stepper motors, and effectively avoids the need to waterproof and dampen the stepper motor, thereby further reducing the manufacturing cost of the water spray mechanism 1.

[0074] Furthermore, in one embodiment, the bottom cover 40 is provided with a limiting notch 402 at its edge, and the fourth side of the housing 10 is provided with a limiting step 17 corresponding to the limiting notch 402, so that the limiting step 17 can be embedded in the limiting notch 402.

[0075] Understandably, when the water spray mechanism 1 requires the connecting shaft 50 to pass through the mounting hole 2201 of the connecting part 22 to be embedded in the limiting hole 401 of the bottom cover 40 to achieve a rotational connection between the rotating part 20 and the bottom cover 40, by making the limiting notch 402 of the bottom cover 40 cooperate with the limiting step 17 on the fourth side of the housing 10, it can effectively ensure that the connection alignment between the housing 10 and the bottom cover 40 is more accurate, so as to prevent the connecting shaft 50 passing through the mounting hole 2201 of the connecting part 22 from being misaligned with the limiting hole 401 and / or the mating hole 114, which would prevent the impeller 23 from rotating.

[0076] In one embodiment, the side of the push rod 30 that abuts against the third side of the rotating member 20 can be specifically arc-shaped, such as partially spherical or partially ellipsoidal, so that it can move relative to the rotating member 20 more conveniently when it abuts against the third side of the rotating member 20.

[0077] Please continue to refer to the following: Figure 11 and Figure 12 ,in, Figure 11 yes Figure 1 A detailed structural diagram of another embodiment of the rotating component in the water spray mechanism. Figure 12 yes Figure 11 Another detailed structural diagram of the rotating component.

[0078] In another embodiment, the water spraying mechanism 1 further includes a drive shaft 60, and the rotating member 20 further includes a control part 21 and a connecting part 22 connected to each other. The control part 21 further includes a first side wall 211 and a second side wall 212. The first side wall 211 is specifically partially cylindrical, and the second side wall 212 is connected to and closes one end opening of the first side wall 211.

[0079] Specifically, the angle σ between the second sidewall 212 and the set direction is an acute angle, and one end of the push rod 30 passes through the opening of the first sidewall 211 and abuts against the second sidewall 212.

[0080] Specifically, one end of the connecting part 22 in the rotating member 20 is connected to the middle of the side of the second side wall 212 away from the push rod 30, while the other end is connected to one end of the transmission shaft 60. The other end of the transmission shaft 60 is further connected to an external drive mechanism, such as a control motor, so that the transmission shaft 60 can be driven by the control motor to rotate the rotating member 20 around the central axis of its connecting part 22, and then the rotating member 20 drives the push rod 30 to extend into the first water outlet pipe 12 in a set direction Z and move back and forth.

[0081] Furthermore, in one embodiment, a sealing element is also provided between the drive shaft 60 and the connection portion 22 of the rotating member 20, and the drive shaft 60 can also be provided outside the housing 10 so as to effectively isolate the drive shaft 60 from the outside of the housing 10 through the sealing element, so as to prevent water inside the housing 10 from flowing out and causing adverse effects on the drive shaft 60 and the corresponding drive mechanism.

[0082] Understandably, the above solution, by adjusting the output power of the control motor, can correspondingly adjust the rotational speed of the drive shaft 60 and the rotating component 20 to achieve different water spray patterns, allowing for convenient adjustment based on user habits. Furthermore, compared to directly pushing the push rod 30 back and forth via electrodes, driving the push rod 30 through the rotating component 20 obviously allows for faster response and high-speed switching, and also allows the control motor to be located externally to the water spray mechanism 1.

[0083] This application also provides a smart toilet, please refer to [link / reference]. Figure 13 , Figure 13 This is a schematic diagram of a framework of one embodiment of the smart toilet of this application. In this embodiment, the smart toilet 70 includes: a water spraying mechanism 71 and a water storage mechanism 72.

[0084] Specifically, the water spraying mechanism 71 further includes a first water inlet pipe 711, which is connected to the water storage mechanism 72 so that the water stored in the water storage mechanism 72 can be introduced into the housing of the water spraying mechanism 71 and then sprayed out.

[0085] Specifically, the water spraying mechanism 71 is the water spraying mechanism 1 as described in any of the preceding items; please refer to [link / reference needed]. Figures 1-12 The relevant textual content will not be repeated here.

[0086] The beneficial effects of this application are as follows: Unlike the prior art, the water spraying mechanism provided in this application has a receiving cavity inside its housing. A first inlet pipe and a first outlet pipe are respectively provided on the adjacent first and second sides of the housing. A rotating component is disposed within this receiving cavity. The angle between the third side of the rotating component facing the first outlet pipe and the set direction is an acute angle; that is, the third side of the rotating component is specifically an inclined plane relative to the opening of the first outlet pipe. One end of the push rod abuts against the third side of the rotating component, and its other end extends along the set direction to allow the rotating component to rotate around the set direction. During rotation, the distance between the area on the third side of the rotating component corresponding to the push rod and the opening of the first water outlet pipe changes continuously with the rotation. This allows the push rod to extend back and forth into the first water outlet pipe in a set direction, constantly adjusting the depth of the push rod's insertion into the first water outlet pipe. This enables the water to be introduced from the first water inlet pipe into the internal cavity of the housing and sprayed out from the first water outlet pipe, rapidly changing the water outlet cross-section to produce different water spray patterns. Furthermore, the periodic back-and-forth movement of the push rod driven by the uniformly rotating component also creates a pulse effect. Compared to directly driving the push rod with a separate power unit, using the rotating component to drive the push rod obviously simplifies the overall structure of the water spray mechanism, makes it easier to install, and reduces implementation costs.

[0087] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
