Description

Technical Field

[0001] The present invention relates to an electric toilet, in particular to an electric toilet with an improved cover plate structure, the IPC classification of which belongs to A47K13 / 12. Background Art

[0002] The cover of an existing toilet is usually flipped by a hinge mechanism. The structure of this type of toilet is shown in the prior patent application with publication number CN207492721U, and the patent name is: A flip cover device for a toilet, which includes a flip cover, a shell with a through hole and a hinge mechanism for connecting the flip cover and the toilet body. The hinge mechanism includes a hinge body with a straight portion, which passes through the through hole of the shell, and its straight portion is fixed by screws and embedded in the nut of the flip cover mounting hole.

[0003] The technical problems existing in the flap device of the existing toilet are:

[0004] 1. The flip cover is connected to the hinge via a nut embedded in its mounting hole via screws. After repeated opening and closing, the nut is easily loosened, causing the flip cover to separate from the hinge and fall off;

[0005] 2. When the flip cover needs to be electrically flipped, the span of the two hinges is large, and the axis of the two is prone to deviation. Using double-sided motors or single-sided motor drive is prone to force imbalance, affecting opening and closing, especially when the plastic parts are deformed. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides an electric toilet with an improved cover structure.

[0007] The technical solution adopted in the present invention is:

[0008] An electric toilet with an improved cover structure comprises a base, a casing fixedly mounted on the base, a seat ring, a bracket, a cover plate and a hinge device. The bracket is injection-molded and fixed to the cover plate, and comprises a support portion and a connecting portion extending from the end of the support portion and forming an angle therewith. The casing is provided with a recessed portion on a side away from the seat ring, and the side wall of the recessed portion is provided with a through hole for the hinge device to pass through. The cover plate and the bracket are limited by the hinge device and are rotatably mounted in the recessed portion. When the cover plate is closed, the casing, the seat ring and the transition connection between the two are covered underneath.

[0009] The electric toilet with an improved cover structure of the present invention utilizes a bracket inserted into a mold as an injection molding component, centrally securing it to the cover. This enhances the strength of the connection between the bracket and the cover, preventing it from becoming loose during use. The bracket is a separate component, and the hinges on either side are spaced relatively close together, minimizing axial deviation and ensuring balanced force, making assembly easier and ensuring smooth opening and closing. Furthermore, the through-holes for the hinges are concealed in the sidewalls of the recessed portion, making them less susceptible to damage from external impacts and preventing water droplets, dust, and other particles from entering the housing.

[0010] Furthermore, the hinged device includes a connecting sleeve, a drive motor fixedly mounted on the housing, a shaft seat, and a bracket hole provided on the connecting portion. The connecting sleeve includes a first connecting sleeve and a second connecting sleeve. The first connecting sleeve has a shaft hole for inserting the drive motor shaft, the second connecting sleeve has a cylindrical rotating shaft, and the shaft seat has a shaft seat hole for inserting the cylindrical rotating shaft. This design allows the cover to be electrically flipped, and the connecting sleeve, with a larger load-bearing area, is mounted on the bracket hole, preventing direct contact between the drive motor shaft and the bracket hole, which could cause wear and tear, thereby extending the service life of the cover.

[0011] Furthermore, a notch is provided at one end of the bracket hole, and the second connecting sleeve is provided with a boss that snaps into the notch. A mounting hole is provided on the cylindrical surface at the other end of the bracket hole, and the first connecting sleeve is provided with a connecting hole. The first connecting sleeve is then mounted on the bracket by screws passing through the mounting hole and the connecting hole. This design facilitates installation, removal, and maintenance of the cover.

[0012] Furthermore, the shaft hole is a stepped hole. Through this design, the lubricating oil can be stored in the stepped hole near the motor, preventing the driving motor lubricating oil from losing too quickly, playing the role of reducing wear and reducing noise.

[0013] Furthermore, the outer circumference of the rotating shaft of the second connecting sleeve is provided with a notched cylinder; the shaft seat comprises a cylindrical body with a shaft seat hole, and the outer circumference of the cylindrical body is provided with radially raised ribs. The cylindrical body is sleeved within the cylindrical body, and the ribs are located within the notch of the cylinder to act as a limiter. This design allows the flip cover to be positioned when opened, preventing the cover from opening too far and colliding with objects behind it, causing damage.

[0014] Furthermore, the hinged device includes a coupling, a drive motor fixedly mounted on the housing, an axle seat, and a bracket shaft mounted on the connecting portion. The axle seat has an axial axle seat hole. One side of the bracket shaft is connected to the drive motor via the coupling, and the other side is inserted into the axle seat hole. This design allows the cover to be electrically flipped, and the connection between the parts is simple and reliable.

[0015] Furthermore, the electric toilet with an improved cover structure also includes an upper protective cover and a lower protective cover. The upper and lower protective covers are mounted on the cover to form a receiving cavity, and the connecting portion is accommodated within the receiving cavity. This design accommodates the connecting portion of the bracket within the receiving cavity, preventing dust from accumulating on the connecting portion and making the toilet structure neater.

[0016] Furthermore, the electric toilet with the improved cover structure also includes a display screen. The housing has a display hole between the lower recess and the seat ring, and the display screen is mounted on the display hole. This design allows the electric toilet information to be displayed on the display screen, allowing users to quickly and intuitively obtain toilet status information through the display screen.

[0017] Furthermore, the bracket's support portion features a light-transmitting hole. The cover is injection-molded to form a hollow cover boss that surrounds the hole. A light-transmitting plate is mounted on this boss, and when the cover is closed, the light-transmitting plate sits above the display screen. This design allows users to view information about the electric toilet even when the cover is closed. Furthermore, the light-transmitting plate is mounted on the cover boss, which is injection-molded around the light-transmitting hole. This strengthens the mounting area for the light-transmitting plate, preventing cracking between the light-transmitting plate and the cover panel due to deformation when a person sits on the cover.

[0018] Furthermore, the electric toilet with the improved cover plate structure further includes a pressing ring, which presses the light-transmitting plate tightly against the cover plate boss. This design facilitates the removal and installation of the light-transmitting plate.

[0019] Furthermore, the lower concave portion includes a curved surface and a sidewall connected to the curved surface. A water guide hole is provided on the curved surface, and a through hole is provided on the sidewall. The distance from the bottom end of the through hole to the horizontal plane is greater than the distance from the top end of the water guide hole facing the through hole to the horizontal plane. This design can guide water accumulated in the lower concave portion to a designated part of the electric toilet for drainage, preventing water from seeping into the casing through the through hole and damaging internal components.

[0020] For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See Figure 2 and Figure 8 The present invention provides an electric toilet with an improved cover structure, which includes a base 100, a housing 200 fixedly mounted on the base, a seat 300, a bracket 400, a cover 500 and a hinge device. Figure 10 As shown, it includes a supporting portion 410 for supporting the cover plate 500 and a connecting portion 420 extending from the end of the supporting portion and forming an angle with the supporting portion 410. Figure 11 The cover plate 500 and the bracket 400 are integrally injection molded. During production, the bracket 400 is placed as an insert into the mold. After injection molding, the bracket 400 is fixed to the cover plate 500. As a specific embodiment, the bracket 400 is a strong plastic bracket or a metal bracket.

[0040] Implementation method one:

[0041] See Figure 1 、 Figure 2 、 Figure 5 、 Figure 9 and Figure 10The hinge device includes a bracket hole 430 fixedly arranged on the connecting portion 420, a shaft 730, and a bearing (not shown). The housing 200 is provided with a lower recess 210 on the side away from the seat ring 300. The wall of the lower recess 210 is provided with a through hole 220 for the shaft 730 to pass through. The shaft 730 is inserted into the bracket hole 430 after passing through the through hole 220, and the bracket 400 and the cover plate 500 are rotatably mounted on the lower recess 210. When the cover plate 500 of the electric toilet is in the closed state, the cover plate 500 covers the housing 200, the seat ring 300, and the transition connection part between the seat ring 300 and the outer shell 200 under the cover plate 500. See Figure 2 In specific implementations, the transitional connection includes a transitional connection L1 where the raised portion of the seat rim's top meets the housing, a transitional connection L2 where the side of the seat rim meets the housing, and a transitional connection L3 where the top of the seat rim meets the housing. Covering these transitional connections with a cover effectively prevents water and dust from falling from above the electric toilet from accumulating in the transitional connection, reducing the risk of dirt and bacteria growing on the toilet.

[0042] The electric toilet with an improved cover structure of the present invention utilizes a bracket inserted into a mold as an injection molding component, centrally securing it to the cover. This enhances the strength of the connection between the bracket and the cover, preventing it from becoming loose during use. The bracket is a separate component, and the hinges on either side are spaced relatively close together, minimizing axial deviation and ensuring balanced force, making assembly easier and ensuring smooth opening and closing. Furthermore, the through-holes for the hinges are concealed in the sidewalls of the recessed portion, making them less susceptible to damage from external impacts and preventing water droplets, dust, and other particles from entering the housing.

[0043] Implementation method 2:

[0044] See Figure 6 、 8 To extend the life of the cover plate by electrically flipping and lifting the cover plate, the electric toilet of this embodiment, unlike the first embodiment, uses an electrically powered hinge mechanism. Specifically, the hinge mechanism includes a bracket hole 430 fixedly disposed on the connecting portion 420, a connecting sleeve mounted on the bracket hole 430, and a drive motor 700 and a shaft seat 800 fixedly mounted on the housing. Figure 7 、 12 13, the connecting sleeve includes a first connecting sleeve 610 and a second connecting sleeve 620. The first connecting sleeve 610 is cylindrical, with an axial shaft hole 611 at one end for inserting the drive motor shaft 710, and a radial connecting hole 612 on the cylindrical surface of the other end. The second connecting sleeve 620 includes a cylindrical bottom 624 and a cylindrical rotating shaft 621 axially protruding from the bottom. Figure 14The shaft seat 800 comprises a base 830 and a cylindrical body 820 protruding axially from the base. The cylindrical body has a shaft seat hole 810 on its axial surface for inserting the cylindrical rotating shaft 621. During assembly, the first and second connecting sleeves 610 and 620 are respectively inserted into the bracket hole 430. The rotating shaft 621 of the second connecting sleeve 620 is then inserted into the shaft seat hole 810 of the shaft seat. The shaft seat 800 is then secured to the housing 200 with screws. Finally, the drive motor shaft 710 is inserted into the shaft hole 611 of the first connecting sleeve, and the drive motor 700 is secured to the housing 200 using the motor bracket 720. Because the bracket 400 is fixed to the cover plate 500 by injection molding, this design avoids direct contact between the smaller diameter drive motor shaft and the bracket hole, which could cause wear. During operation, the force transmitted by the drive motor shaft is primarily concentrated on the shaft hole of the first connecting sleeve. If the first connecting sleeve becomes damaged or slips, it can simply be replaced, reducing maintenance costs. Of course, as another embodiment, the connecting sleeve may be eliminated, and the drive motor shaft 710 may be directly inserted into the bracket hole 430 , and the drive motor 700 may be rotated to drive the bracket 400 and the cover plate 500 to rotate.

[0045] See Figure 7 and Figure 12 In order to prevent the lubricating oil of the driving motor from being lost too quickly, reduce the wear of the driving motor and reduce the noise of the driving motor during operation, the shaft hole 611 is a stepped hole in which lubricating oil is stored.

[0046] To facilitate the processing of parts and the installation, removal and maintenance of the cover, see Figure 10 As shown, a notch 431 is provided at one end of the bracket hole 430 of the bracket, and a mounting hole 432 is provided on the cylindrical surface at the other end. Figure 12 and 13 The first connecting sleeve 610 is installed on the bracket 400 by screws through the mounting hole 432 and the connecting hole 612. The bottom 624 of the second connecting sleeve 620 is radially protruding to engage the boss 622 of the notch 431. Furthermore, in order to prevent the cover from being damaged by colliding with objects behind it when it is turned over, Figure 13 and Figure 14 The second connecting sleeve 620 is provided with a notched cylinder 623 on the outer periphery of the rotating shaft 621, and the side of the cylindrical body 820 of the shaft seat 800 is provided with radially raised ribs 821. During assembly, the cylindrical body 820 is inserted into the hole of the cylinder 623. The notch in the cylinder 623 limits the rotation angle of the rib 821, thereby limiting the tilting angle of the cover plate 500.

[0047] See Figure 4 and Figure 8The electric toilet with an improved cover structure also includes an upper protective cover 11 and a lower protective cover 12. The connecting portion 420 is exposed on the cover 500. The upper and lower protective covers 11 and 12 are mounted on the cover 500 to form a receiving cavity 10, which accommodates the connecting portion 420. This design allows the connecting portion of the bracket to be accommodated in the receiving cavity, preventing dust from accumulating on the connecting portion and keeping the toilet cleaner.

[0048] See Figure 4 and Figure 8 The electric toilet with an improved cover structure also includes a display screen 900. The housing 200 has a display hole 230 defined on the surface between the lower recess 210 and the seat 300, and the display screen 900 is mounted on the display hole 230. This design allows the electric toilet to display information on the display screen, allowing users to quickly and intuitively obtain toilet status information.

[0049] As a preferred embodiment of the present invention, the electric toilet with improved cover structure further includes a display screen upper shell 910, a display screen lower shell 920 and a sealing strip 930. Figure 4 The sealing strip 930 is disposed between the housing 200 and the upper display housing 910. The upper display housing 910 covers the display hole 230 and, when assembled with the lower display housing 920, forms a display housing cavity 20. The display 900 is disposed within this cavity 20. This design provides better waterproofing for the display, preventing water from dripping directly onto the display from above the housing and causing damage.

[0050] Preferably, see Figure 4 、 8 , 10, and 11, the electric toilet with the improved cover structure also includes a light-transmitting plate 940. A light-transmitting hole 411 is provided on the support portion of the bracket. The cover 500 is injection-molded to form a hollow cover boss 510 that surrounds the peripheral wall of the light-transmitting hole 411. The light-transmitting plate is mounted on the cover boss 510. When the cover 500 is closed, the light-transmitting plate 940 is located directly above the display screen 900. This design allows the user to view information about the electric toilet even when the cover is closed. Furthermore, the light-transmitting plate is mounted on the cover boss with a through hole, which is injection-molded around the light-transmitting hole. This design improves the strength of the light-transmitting plate mounting point, preventing cracking between the light-transmitting plate and the cover due to deformation when a person sits on the cover.

[0051] See Figure 4 In order to facilitate the installation, removal and replacement of the light-transmitting plate, the electric toilet with the improved cover plate structure also includes a pressing ring 950, which is buckled and fixed on the cover plate boss and presses the light-transmitting plate 940 at the same time.

[0052] See Figure 9The lower recess 210 of the housing includes a curved surface 211 and a sidewall 212 connected to the curved surface. A water guide hole 213 is provided on the curved surface 212, and a through hole 220 is located on the sidewall 212. The distance H1 from the bottom of the through hole to the horizontal plane is greater than the distance H2 from the top of the water guide hole 213 facing the through hole 220 to the horizontal plane. This design guides water accumulated in the lower recess to a designated area of the electric toilet for drainage, preventing water from seeping into the housing through the through hole and damaging internal components.

[0053] Implementation method three:

[0054] See Figures 15 to 17 In order to realize the electric flipping of the cover and simplify the connection structure between parts, the electric toilet of this embodiment is distinguished from the second embodiment by adopting a different structure of the bracket 400' and an electric hinge device. Figure 15 As shown, the bracket 400' of this embodiment is also fixed on the cover plate 500 by injection molding, and includes a support portion 410' and a connecting portion 420' extending from the end of the support portion and forming an angle with the support portion 410'. Figure 16 and 17 The hinge device of this embodiment includes a coupling 600, a drive motor 700 fixedly mounted on the housing 200, an axle seat 800, and a bracket shaft 430' disposed on the connecting portion 420'. The axle seat 800 is provided with an axial axle seat hole 810. During installation, one side of the bracket shaft 430' is connected to the drive motor 700 via the coupling 600, while the other side of the bracket shaft 430' is inserted into the axle seat hole 810 mounted on the axle seat. Of course, in other embodiments, the bracket shaft can also be designed to pass through the through hole in the lower recess to connect to the hinge device disposed in the housing.

[0055] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications of the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims of the present invention and equivalent technologies, the present invention is also intended to include these changes and modifications.
