Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a quick-release structure for a smart toilet seat, a smart toilet seat with a quick-release structure, and a smart toilet. Background Technology

[0002] Currently, smart toilets on the market typically consist of a smart seat and a ceramic body. The smart seat is usually bolted to the ceramic body. While this design ensures installation stability, it reveals significant maintenance challenges in daily use. Because the bolts are usually hidden inside the smart seat or in a recessed area at the rear, users need to bend over or even use tools to remove them, which is not only laborious but can also scratch the ceramic surface due to the complex structure. Especially during deep cleaning, the narrow gap between the rear of the ceramic body and the wall easily accumulates dirt, but the cumbersome steps of removing the smart seat deter many people from thorough cleaning, potentially leading to bacterial growth over time. Furthermore, for repairs such as replacing the filter or checking the circuitry, technicians often have to spend time disassembling the entire smart seat, increasing service costs and time.

[0003] As can be seen from the above, the smart covers currently on the market are difficult to disassemble, difficult to clean, and difficult to repair. In view of this, the designer of this utility model designed and developed this utility model. Utility Model Content

[0004] The main purpose of this utility model is to provide a quick-release structure for an intelligent cover, which is easy to disassemble, clean, and repair.

[0005] Another objective of this invention is to provide an intelligent cover with a quick-release structure.

[0006] Another objective of this utility model is to provide a smart toilet.

[0007] To achieve the above objectives, the present invention adopts the following solution:

[0008] A quick-release structure for an intelligent cover includes: a base plate, a sliding plate, a pulling component, and a positioning component. The positioning component is inserted through the base plate, and the sliding plate is slidably installed on the base plate. The sliding plate is provided with a locking component, which can unlockably lock the positioning component. The pulling component selectively pulls the sliding plate away from the positioning component, thereby releasing the locking component from locking the positioning component.

[0009] Furthermore, the limiting buckle has a locking opening, the positioning member is provided with a locking groove, and the inner side of the locking opening is provided with a locking edge. When the locking member moves to the locking position, the locking edge engages with the locking groove. When the locking member moves to the unlocking position, the locking edge exits the locking groove.

[0010] Furthermore, the base plate is provided with a first slide rail, the limiting buckle is housed in the first slide rail, the outer end of the limiting buckle is provided with a first hook, the outer end of the first slide rail is recessed with a limiting groove, and the first hook slides along the limiting groove.

[0011] Furthermore, the pulling assembly includes a steel wire rope and a compression spring. The base plate is provided with a limiting seat, the compression spring is disposed between the limiting seat and the slide plate, the steel wire rope extends through the compression spring, and the head of the steel wire rope is installed inside the slide plate. As the steel wire rope pulls the slide plate, the compression spring will be compressed and deformed.

[0012] Furthermore, the skateboard is also provided with a spring-loaded fastener, and the base plate is also provided with a second slide rail. The spring-loaded fastener is housed within the second slide rail. The spring-loaded fastener has a second hook protruding from the wall of the second slide rail, and the end of the spring-loaded fastener has a locking portion protruding from the positioning member. The inner wall of the second slide rail is provided with a locking slot. When the locking member moves to the unlocked position, the positioning member abuts against the locking portion, causing the spring-loaded fastener to deform outward, and the second hook will then hook into the locking slot. When the positioning member separates from the spring-loaded fastener, the spring-loaded fastener resets, causing the second hook to disengage from the locking slot.

[0013] Furthermore, the limiting seat has a first limiting groove recessed in the lower part, a fixing block is detachably installed on the limiting seat, the fixing block has a second limiting groove recessed in the lower part, the wire rope has a rope sleeve, the head of the rope sleeve is fixed between the first limiting groove and the second limiting groove; the head of the wire rope is a locking block, a chamber is provided below the sliding plate, the locking block is detachably installed in the chamber, the chamber has a through hole, and the wire rope passes through the through hole.

[0014] Furthermore, a quick-release structure for an intelligent cover also includes a button box, which has a button and a swing block. One end of the swing block is driven by the button, and the other end is driven by at least one of the pull components. When the button is pressed, the swing block pulls the pull component, causing the pull component to pull the slide away from the positioning member, and the locking member releases the locking of the positioning member. When the button is released, the locking member resets the locking of the positioning member.

[0015] A smart cover with a quick-release structure, comprising the quick-release structure of the aforementioned smart cover.

[0016] A smart toilet includes: a ceramic body and the aforementioned smart seat, wherein the base plate, sliding plate, and pull assembly are mounted on one of the ceramic body and the smart seat, and the positioning member is mounted on the other of the smart seat and the ceramic body, such that the smart seat is detachably mounted on the ceramic body.

[0017] Furthermore, the quick-release structure of the smart cover also includes a micro switch. The ceramic body is equipped with a transmission component and a liftable guide post. The smart cover is installed on the guide post. The pulling component is linked with the micro switch. The micro switch drives the transmission component to work, causing the guide post to rise and lift the smart cover. The transmission component includes a meshing rack and an output gear. The micro switch controls the output gear to rotate, and the rack drives the guide post to move up and down.

[0018] As can be seen from the above technical solution, this utility model, through the cooperative structure of the base plate, slide plate, pulling component, and positioning component, allows users or technicians to install the base plate, slide plate, and pulling component onto the ceramic body or smart cover, and the positioning component onto the smart cover or ceramic body. The locking component on the slide plate locks the positioning component, thus fixing the smart cover to the ceramic body and ensuring normal use. When users or technicians need to disassemble, repair, or clean, they can pull the slide plate away from the positioning component using the pulling component, causing the locking component to release its lock on the positioning component. This allows the smart cover to be quickly removed from the ceramic body or quickly unlocked, allowing the lifting device to lift the smart cover, achieving the characteristics of easy disassembly, convenient cleaning, and easy repair.

[0049] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0050] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0051] Reference Figures 1-9 As shown, this utility model discloses a quick-release structure for an intelligent cover plate 2, including: a base plate 21, a sliding plate 22, a pulling component 24, and a positioning component 11. The positioning component 11 is inserted through the base plate 21, and the sliding plate 22 is slidably installed on the base plate 21. The sliding plate 22 is provided with a locking component, which can unlockably lock the positioning component 11. The pulling component 24 selectively pulls the sliding plate 22 away from the positioning component 11, thereby releasing the locking component from locking the positioning component 11.

[0052] The locking mechanism can restore the locking of the positioning component 11. It can be restored by manual installation or by setting an automatic reset structure to allow the locking mechanism to restore the locking of the positioning component 11. In the embodiment shown in the figure, the locking mechanism is restored to the locking of the positioning component 11 by setting an automatic reset structure.

[0053] Therefore, through the cooperative structure of the base plate 21, the slide plate 22, the pulling component 24, and the positioning component 11, this utility model allows users or technicians to install the base plate 21, the slide plate 22, and the pulling component 24 onto the ceramic body 1 or the smart cover 2, and to install the positioning component 11 onto the smart cover 2 or the ceramic body 1. The locking component on the slide plate 22 locks the positioning component 11, thus achieving the installation and fixation of the smart cover 2 and the ceramic body 1, ensuring normal use by the user. When users or technicians need to disassemble, repair, or clean, they can pull the slide plate 22 away from the positioning component 11 by using the pulling component 24, thereby releasing the locking component from the positioning component 11. This allows the smart cover 2 to be quickly removed from the ceramic body 1 or to be quickly unlocked so that the lifting device can lift the cover 2, achieving the characteristics of easy disassembly, easy cleaning, and easy repair.

[0054] In this embodiment, the locking component is a limiting buckle 221, which has a locking opening 222. The positioning component 11 is provided with a locking groove 111. The inner side of the locking opening 222 is provided with a locking edge 2221. When the locking component moves to the locking position, the locking edge 2221 engages with the locking groove 111. When the locking component moves to the unlocking position, the locking edge 2221 disengages from the locking groove 111. Thus, by utilizing the structural cooperation between the inner side of the locking opening 222 and the locking groove 111, the locking component can quickly lock the positioning component 11. However, this is not a limitation, and other locking structures can also be used, such as a locking pin and a locking hole.

[0055] Furthermore, the base plate 21 is provided with a first slide rail 211, and the limiting buckle 221 is accommodated within the first slide rail 211. The outer end of the limiting buckle 221 is provided with a first hook 223, and the outer end of the first slide rail 211 is recessed with a limiting groove 212. The first hook 223 slides along the limiting groove 212, so that when the positioning member 11 is aligned with the locking edge 2221, as... Figure 3 As shown, the locking edge 2221 engages with the positioning element 11. When the intelligent cover 2 of this utility model needs to be disassembled, the pulling component 24 pulls the sliding plate 22 away from the positioning element 11. The positioning element 11 moves from the inside of the locking opening 222 to the outside of the locking opening 222 until it is positioned on the outside of the locking opening 222. Figure 5 As shown, the positioning member 11 releases the lock, the locking edge 2221 exits the locking groove 111, the positioning member 11 can be disengaged from the limiting buckle 221, and the smart cover 2 can be disassembled. The first hook member 223 is restricted by the limiting groove 212 to limit the maximum moving distance that the limiting buckle 221 can be pulled.

[0056] In this embodiment, the pulling component 24 may include a steel wire rope 241 and a compression spring 242. The base plate 21 is provided with a limiting seat 215. The compression spring 242 is disposed between the limiting seat 215 and the slide plate 22. The steel wire rope 241 extends through the compression spring 242. The head of the steel wire rope 241 is installed in the slide plate 22. As the steel wire rope 241 pulls the slide plate 22, the compression spring 242 will be compressed and deformed. Thus, the elastic recovery of the compression spring 242 can be used to restore the locking component 11.

[0057] Furthermore, the skateboard 22 may also be provided with a spring-loaded buckle 224, and the base plate 21 may also be provided with a second slide rail 213. The spring-loaded buckle 224 is accommodated within the second slide rail 213. The spring-loaded buckle 224 has a second hook 226 protruding from the wall of the second slide rail 213, and the end of the spring-loaded buckle 224 has a locking portion 225 protruding from the positioning member 11. The inner wall of the second slide rail 213 is provided with a locking slot 214. When the locking member moves to the unlocked position, the positioning member abuts against the locking portion, causing the spring-loaded buckle to deform outward, thereby releasing the second hook 226. When the positioning member 11 separates from the spring buckle 224, the spring buckle 224 resets, causing the second hook 226 to disengage from the buckle 214. Thus, when the steel wire rope 24 pulls the slide plate 22 to unlock, the spring buckle 224 self-locks and hooks the slide plate 226, preventing the slide plate 22 from returning to its original position under the action of the compression spring 242. This prevents the positioning member 11 from disengaging from the spring buckle 224 before the compression spring 242 elastically recovers, causing the positioning member 11 to be unable to disengage from the limit buckle 221.

[0058] Furthermore, the number of the spring-loaded fasteners 224 can be two, and the locking parts 225 can selectively engage the positioning parts 11, thereby using the locking parts 225 to engage the positioning parts 11 to securely install the smart cover 2 of this utility model with the ceramic body 1.

[0059] In this embodiment, the limiting seat 215 is recessed to form a first limiting groove 216, and a fixing block 23 is detachably installed on the limiting seat 215. The fixing block 23 is recessed to form a second limiting groove 231. The wire rope 241 has a rope sleeve 243, and the head 2431 of the rope sleeve is fixed between the first limiting groove 216 and the second limiting groove 231, thereby protecting the wire rope 241 with the rope sleeve 243. The cooperation between the first limiting groove 216 and the second limiting groove 231 makes it easy to fix the head 2431 of the rope sleeve.

[0060] The fixing block 23 is installed and fixed on the limiting seat 215 by two spaced screws 10; the base plate 21 is also recessed to form an installation chamber 217, the slide plate 22 is disposed in the installation chamber 217, and the installation chamber 217 is located between the limiting seat 215 and the first slide rail 211 and the second slide rail 213.

[0061] Furthermore, to facilitate the installation of the wire rope 241, the head of the wire rope 241 is a locking block 2411, and a chamber 227 is provided below the sliding plate 22. The locking block 2411 is detachably installed in the chamber 227, and the chamber 227 is provided with a through hole 228 through which the wire rope 241 passes. The bottom of the chamber 227 can be open.

[0062] In this embodiment, the quick-release structure of the smart cover 2 of this utility model further includes a button box 12. The button box 12 is provided with a button 121 and a swing block 122. One end of the swing block 122 is driven by the button 121, and the other end is driven by at least one of the pulling components 24. The tail of the rope loop 243 is fixedly installed in the button box 12. When the button 121 is pressed, the swing block 122 pulls the pulling component 24, causing the pulling component 24 to pull the slide plate 22 further away. When the button 121 is pressed, the swing block 122 pulls the steel wire rope 241, causing the steel wire rope 241 to pull the slide plate 22 away from the positioning member 11; when the button 121 is released, the locking member resets its locking on the positioning member 11. Thus, by utilizing the cooperation of the button 121, the swing block 122 and the pulling assembly 24, it is possible to easily control the pulling assembly 24 to pull the slide plate 22 away from the positioning member.

[0063] Furthermore, there are two pulling components 24 and one button 121. When the button 121 is pressed, the swing block 122 pulls the two pulling components 24 at the same time. The pulling components 24 are respectively arranged on the left and right sides of the smart cover 2, which facilitates the secure installation of the smart cover 2 and the ceramic body 1, and facilitates unlocking by controlling the button 121, thus simplifying the structure.

[0064] Furthermore, this utility model also discloses a smart cover plate 2 with a quick-release structure, including the aforementioned quick-release structure of the smart cover plate 2.

[0065] In addition, this utility model also discloses a smart toilet 01, including: a ceramic body 1 and the aforementioned smart seat 2, wherein the base plate 21, the sliding plate 22, and the pulling component 24 are installed on one of the ceramic body 1 and the smart seat 2, and the positioning component 11 is installed on the other of the smart seat 2 and the ceramic body 1, so that the smart seat 2 is detachably installed on the ceramic body 1.

[0066] The button box 12 can be disposed on the ceramic body 1; in the embodiment shown in the figure, the base plate 21, the slide plate 22, and the pull component 24 are installed on the smart cover plate 2, and the positioning component 11 is installed on the ceramic body 1; the positioning component 11 adopts a positioning pin, and the positioning pin is fixed to the ceramic body 1 by screwing.

[0067] like Figures 7-10 As shown, the smart toilet of this utility model also includes a micro switch 123, which is located inside the button box 12. The ceramic body 1 is provided with a transmission component 13 and a liftable guide post 14. The smart toilet seat 2 is installed on the guide post 14. The pulling component 24 is linked with the micro switch 123. When the swing block 122 pulls the pulling component 24 until the swing block 122 contacts the micro switch 123, the micro switch 123 drives the transmission component 13 to work, causing the guide post 14 to rise and lift the smart toilet seat 2. This improves the convenience for users or technicians to remove the smart toilet seat 2 from the ceramic body 1, and enables one-button unlocking and lifting of the smart toilet seat 2.

[0068] Furthermore, the transmission assembly 13 includes a meshing rack 131 and an output gear 132. The micro switch 123 controls the output gear 132 to rotate, and the rack 131 drives the guide column 14 to move up and down.

[0069] The transmission component 13, the liftable guide column 14, and the micro switch 123 of this utility model constitute a lifting device.

[0070] In summary, in the initial state, under the action of the compression spring 242, the upper limit buckle 2214 of the slide plate 22 is inserted into the locking groove 111 on the positioning member 11. At this time, the slide plate 22 is locked by the positioning member 11, and the smart cover 2 cannot be lifted, thus being in a locked state. When unlocking, the mechanical limit of the smart cover 2 must be unlocked first, and then the lifting of the smart cover 2 can be initiated. This avoids forcibly lifting the smart cover 2 when the front end is not unlocked. Specifically, pressing the button 121 on the button box 12 on the smart cover 2 drives the steel wire rope 241 to pull the slide plate. 22. The spring buckle 224 of the lower layer of the slide plate 22 deforms and expands outward due to being blocked by the positioning member 11. The second hook 226 on the spring buckle 224 hooks the slot 214 of the base plate 21 to achieve self-locking and prevent the slide plate 22 from returning to its original position under the action of the compression spring 242. When the smart cover 2 is lifted, the slide plate 22 leaves the positioning member 11, the lower layer spring buckle 221 of the slide plate 22 deforms and recovers, the second hook 226 on the spring buckle 224 no longer hooks the slot 214 of the base plate 21, and returns to its initial position under the action of the elastic restoring force of the compression spring 242.

[0071] It should be understood that the various examples described above can be utilized in multiple directions, such as tilted, inverted, horizontal, vertical, etc., and in multiple configurations, without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and this invention is not limited to any specific details of these embodiments.

[0072] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
