Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a closed-lid flushing structure for a smart toilet and a smart toilet. Background Technology

[0002] Smart toilet seats are a modern home appliance that offers many convenient and hygienic features, such as automatic flushing, warm air drying, and heated seats. However, these smart features may be affected during power outages, preventing users from fully enjoying the convenience of a smart toilet seat.

[0003] In the event of a power outage, the automatic flushing function of smart toilet seats typically fails because they rely on the household's power supply. In this case, users need to take alternative measures to flush. A common practice is to manually flush the toilet using bottled water. While this solves the problem, it is clearly inconvenient and unhygienic, as it requires the user to manually carry the water bucket and flush.

[0004] Another solution is to have a separate flush button on the smart toilet's control panel that can be manually activated during a power outage. This button would be powered by an independent source, such as a battery. This way, even during a power outage, the user can still flush manually by operating this button. However, this approach may increase operational complexity, as the user needs to remember to use this manual button during a power outage, and the additional button might affect the aesthetic design of the smart toilet seat, making it look less neat and modern.

[0016] Another type of smart toilet is provided, which has the closing flushing structure of the smart toilet described above.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model provides a flushing structure for a smart toilet with a closed lid. Compared with the prior art, this utility model has at least the following technical effects: 1. By setting a sensing device and a triggering device at the connection between the toilet seat body and the top cover, and driving the triggering device through the rotating shaft connecting the toilet seat body and the top cover, the triggering device can trigger the sensing device to perform flushing when the top cover is closed, so that flushing can be performed even in the event of a power outage. The operation is simple and convenient, and there is no need to press an additional button to flush. Moreover, the triggering sensing device and the triggering device are integrated at the connection between the top cover and the toilet seat body, eliminating the need for a separate flushing button on the control panel and not affecting the appearance of the seat. 2. By closing the top cover, the rotating shaft is driven to rotate, which in turn moves the trigger rod to trigger the sensing device. There is no need to set a separate flushing button on the control panel, meeting the flushing needs when the water supply is interrupted. 3. A guide sleeve is provided to guide the movement of the trigger rod, so that when the lid is closed, the rotating shaft can push the trigger rod to move along the guide sleeve to accurately trigger the sensing device. 4. A first handle is provided on the rotating shaft, and a second handle is provided on the trigger rod. These two handles cooperate to facilitate the rotating shaft driving the trigger rod to move when the cover is closed, completing the flushing operation in the power-off state. 5. When the trigger rod is activated, the distance between the contact point of the first handle and the axis of the rotating shaft is greater than or equal to the distance between the far end of the second handle and the axis of rotation of the rotating shaft, so that the first handle and the second handle abut against each other. This allows the first handle to contact the second handle and push it to move when the rotating shaft rotates, thus triggering the sensing device to flush. 6. A clearance hole is provided on the guide sleeve to facilitate the second handle extending and contacting the first handle; a guide groove is provided inside the guide sleeve, and a guide block is provided on the trigger rod to ensure smooth and stable sliding of the trigger rod. 7. A reset component is provided on the trigger rod to drive it back to its initial position, ensuring that it is in a position capable of driving the rotating shaft when the cover is closed next time.

[0019] This invention provides a smart toilet with a closed-lid flushing structure. Compared to existing technologies, this invention offers at least the following technical advantages: 1. By incorporating a sensor and a trigger device at the connection between the toilet seat body and the top cover, and driving the trigger device via a rotating shaft connecting the toilet seat body and the top cover, the trigger device can activate the sensor to perform flushing when the top cover is closed. This allows for flushing even during power outages, simplifying operation and eliminating the need for additional button presses. Furthermore, the integrated sensor and trigger device at the connection between the top cover and the toilet seat body eliminates the need for a separate flushing button on the control panel, preserving the seat's appearance. 2. A guide sleeve guides the movement of the trigger rod, enabling the rotating shaft to push the trigger rod along the guide sleeve to accurately trigger the sensor when the lid is closed. A first shaft handle is provided on the rotating shaft, and a second shaft handle is provided on the trigger rod. These two handles work together to facilitate the rotating shaft driving the trigger rod to move when the top cover is closed, completing the flushing operation even during power outages.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1 to 8 A smart toilet with a closed-lid flushing structure includes an upper cover 2 rotatably mounted on a toilet seat body 1, and a switch assembly disposed on the toilet seat body 1. The switch assembly includes a sensing device 3 and a triggering device 4. The upper cover 2 is rotatably connected to the toilet seat body 1 via a rotating shaft 5. The sensing device 3 and the triggering device 4 are disposed at the connection between the upper cover 2 and the toilet seat body 1. The triggering device 4 is drively connected to the rotating shaft 5, and the rotating shaft 5 drives the triggering device 4 to trigger the sensing device 3. By installing a sensor 3 and a triggering device 4 at the connection between the toilet seat body 1 and the upper cover 2, and driving the triggering device 4 via a rotating shaft 5 connecting the toilet seat body 1 and the upper cover 2, the triggering device 4 can activate the sensor 3 to perform flushing when the upper cover 2 is closed. This allows for flushing even during power outages, making operation simple and convenient without the need for additional button presses. Furthermore, the triggering device 3 and triggering device 4 are integrated at the connection between the upper cover 2 and the toilet seat body 1, eliminating the need for a separate flushing button on the control panel and preserving the appearance of the seat. The triggering device 4 and sensor 3 are located adjacent to the rear shell bushing 6 of the toilet seat body 1. The rotating shaft 5 can be an ivory shaft.

[0031] Please see Figures 1 to 8 Preferably, the triggering device 4 includes a trigger rod 41, and the rotating shaft 5 is tractively connected to the trigger rod 41. The rotation of the rotating shaft 5 drives the trigger rod 41 to move and contact the sensing device 3. By closing the upper cover 2 to drive the rotating shaft 5 to rotate, thereby moving the trigger rod 41 to trigger the sensing device 3, there is no need to set a separate flush button on the operation panel, which meets the need for flushing when the water supply is interrupted.

[0032] Please see Figures 1 to 8Preferably, the triggering device 4 includes a guide sleeve 42, which is installed on the toilet seat body 1. The trigger rod 41 is disposed in the guide sleeve 42 and can slide within the guide sleeve 42. The sensing device 3 is opposite to one end of the guide sleeve 42. The guide sleeve 42 guides the movement of the trigger rod 41, so that when the lid is closed, the rotating shaft 5 can push the trigger rod 41 to move along the guide sleeve 42 to accurately trigger the sensing device 3. Preferably, the sensing device 3 is a micro switch, and the contacts of the micro switch are opposite to the trigger rod 41. The micro switch is connected to the main board of the toilet seat body 1, and the flush port on the main board is powered by either AC power or dry cell batteries. The toilet seat body 1 is a main board. The flushing port on the main board is powered by either AC power or dry cell batteries. In this embodiment, the dry cell battery is used, so that flushing can be triggered when the AC power fails. The main board program is designed so that the toilet automatically flushes when AC power is on, and flushes when the AC power fails by triggering a sensor when the lid is closed. The main board program control is existing technology and will not be described in detail.

[0033] Please see Figures 1 to 8 Preferably, the triggering device 4 further includes a first shaft 43 and a second shaft 44. The first shaft 43 is located at the end of the rotating shaft 5, and the second shaft 44 is located on the trigger rod 41. The first shaft 43 rotates synchronously with the rotating shaft 5, and the first shaft 43 can actuate the second shaft 44 to drive the trigger rod 41 to move along the guide sleeve 42 to trigger the sensing device 3. The second shaft 44 is perpendicular to the trigger rod 41, and the sensing device 3 is located on the movement path of the trigger rod 41. The first shaft 43 is located on the rotating shaft 5, and the second shaft 44 is located on the trigger rod 41. The two cooperate with each other to facilitate the rotating shaft 5 driving the trigger rod 41 to move when the top cover 2 is closed, thus completing the flushing operation in the power outage state.

[0034] Please see Figures 1 to 8 Preferably, when the trigger lever 41 is in its initial or reset state (e.g. Figure 6 As shown), the contact end of the first shaft handle 43 does not contact the second shaft handle 44, and the contact end of the first shaft handle 43 is disengaged from the second shaft handle 44; when the trigger rod 41 is in the triggered state, the distance between the contact point of the first shaft handle 43 and the axis of the rotating shaft 5 is greater than or equal to the distance from the end of the contact end of the second shaft handle 44 to the axis of rotation of the rotating shaft 5 so that the first shaft handle 43 and the second shaft handle 44 abut against each other, the contact end of the first shaft handle 43 contacts the second shaft handle 44 and moves the second shaft handle 44, so that when the rotating shaft 5 rotates, the first shaft handle 43 can contact the second shaft handle 44 and push the second shaft handle 44 to move, that is, the trigger rod 41 moves to trigger the sensing device 3 to flush.

[0035] Please see Figures 1 to 2 , Figures 6 to 8 Preferably, the guide sleeve 42 has a clearance hole 421 on its side wall, through which the second shaft 44 passes; the guide sleeve has a guide groove 422 on its inner wall, and the trigger rod 41 has a guide block 411 on its circumferential surface, the guide block 411 being located in the guide groove 422. The clearance hole 421 on the guide sleeve 42 facilitates the extension of the second shaft 44 to contact the first shaft 43; the guide groove 422 inside the guide sleeve 42 and the guide block 411 on the trigger rod 41 ensure smooth and stable sliding of the trigger rod.

[0036] Please see Figures 1 to 8 Preferably, the contact ends of the first shaft 43 and the second shaft 44 are arc-shaped; or the contact ends of the first shaft 43 and the second shaft 44 are polygonal; or the contact ends of the first shaft 43 and the second shaft 44 are arc-shaped, wherein the contact length between one side of the first shaft contact end and the contact end of the second shaft 44 is less than that of the other side. The shapes can be any and are not limited thereto, as long as they can contact each other to achieve pushing. See Appendix. Figure 2 , Figure 6 , Figure 7 , Figure 8 The first shaft 43 has a more convex arc on one side and a more inward curve on the other side, so that the contact time between the first shaft 43 and the second shaft 44 is shorter, which can shorten the stroke of the trigger sensing.

[0037] Please see Figures 1 to 2 , Figures 6 to 8 Preferably, the triggering device 4 further includes a reset member, which is disposed between the trigger rod 41 and the guide sleeve 42, for resetting to the initial position after the trigger rod 41 triggers the sensing device 3. The reset member on the trigger rod 41 drives the trigger rod 41 to reset to the initial position, ensuring that it is in a position capable of transmitting power with the rotating shaft 5 during the next closing of the cover.

[0038] Please see Figures 1 to 2 , Figures 6 to 8Preferably, the reset component includes a first spring 45 and a second spring 46. The first spring 45 is installed on the side of the trigger rod 41 near the sensing device 3, and the second spring 46 is installed on the side of the trigger rod 41 away from the sensing device 3. The trigger rod 41 is provided with an abutment portion 412. One end of the first spring 45 and the second spring 46 abuts against the abutment portion 412, and the other end of the first spring 45 abuts against the inner end of the guide sleeve 42 near the sensing device 3. The other end of the second spring 46 abuts against the inner end of the guide sleeve 42 away from the sensing device 3. With the first spring 45 and the second spring 46 respectively provided at both ends of the trigger rod 41, the trigger rod 41 is in a balanced state under the action of the springs at both ends.

[0039] Another smart toilet is provided, which features the closing flushing structure described above. This closing flushing structure incorporates a sensor 3 and a triggering device 4 at the connection between the toilet seat body 1 and the upper cover 2. The triggering device 4 is driven by a rotating shaft 5 connecting the toilet seat body 1 and the upper cover 2, allowing the triggering device 4 to activate the sensor 3 to perform flushing when the upper cover 2 is closed. This enables flushing even during power outages, simplifying operation and eliminating the need for additional button presses. Furthermore, the sensor 3 and triggering device 4 are integrated into the connection between the upper cover 2 and the toilet seat body 1, eliminating the need for a separate flushing button on the control panel and preserving the appearance of the seat.

[0040] The working principle of this utility model is as follows:

[0041] When a power outage occurs, during the closing process, the upper cover 2 drives the rotating shaft 5 to rotate, which in turn drives the first shaft 43 on the rotating shaft 5 to rotate to the right, applying force to the second shaft 44 of the trigger rod 41. This overcomes the resistance of the first spring 45, causing the trigger rod 41 to move to the right and touch the micro switch to close. The micro switch sends a command to the flushing port to issue a flushing command, so that the flushing function can be triggered even in the event of a power outage.

[0042] During the process of continuing to close the cover until it is completely closed, the first shaft 43 continues to rotate to the right until it disengages from the second shaft 44. When it disengages from the second shaft 44, the first spring 45 drives the trigger rod 41 to move in the opposite direction to the micro switch. The trigger rod 41 returns to its initial position and no longer contacts the micro switch.

[0043] When the top cover 2 is flipped up, the first shaft 43 of the rotating shaft 5 of the top cover 2 rotates to the left and applies force to the second shaft 44. The trigger rod 41 moves in the opposite direction to the micro switch and does not touch the micro switch to work.

[0044] When the top cover 2 continues to flip up, the rotating shaft 5 of the top cover 2 continues to drive the first shaft 43 to rotate in the opposite direction. The first shaft 43 and the second shaft 44 disengage. The second spring 46 drives the trigger rod 41 to stop moving in the opposite direction and move towards the micro switch. However, due to the obstruction of the first spring 45, it can only return to the initial position and cannot contact the micro switch.

[0045] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0046] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0047] Finally, the above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.

[0048] It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this utility model should also be considered within the scope of protection of this utility model.
