Description

Technical Field

[0001] The invention relates to the technical field of bathroom equipment, and in particular to a wire-receiving mechanism and bathroom equipment having the wire-receiving mechanism. Background Art

[0002] With the popularity of smart homes, various wires of electrical appliances have brought great troubles to people's lives: longer wires are more likely to get tangled, and it takes time to straighten them out every time the appliance is used or disassembled, affecting the experience; shorter wires are troublesome to disassemble, affecting installation and replacement.

[0003] The same problem also exists in bathroom equipment such as smart toilets or hidden water tanks. In particular, most smart toilets are currently equipped with functional components such as heating elements or sensing elements on their covers, which usually require various control lines to connect to the control board. In the existing structure, one end of these control lines is passed through the shaft hole provided on the rotating shaft of the toilet cover and then connected to the control board. During the process of disassembling and cleaning the toilet cover, the length of the wire affects the cleaning of the dead corners of the upper cover or the seat ring.

[0004] In order to automatically retract the length of the wires, there are some automatic wire retracting structures on the market to straighten the wires. However, the existing automatic wire retracting structures either automatically retract the wires after they are pulled out and cannot limit the length of the pulled wires, which is inconvenient to install, or they can determine the length of the pulled wires, but when they are retracted, they need to press a button to automatically retract, which increases the operation steps and is not convenient and concise to use.

[0055] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0056] First embodiment (the return wheel reciprocates and drives the limiting body to reciprocate):

[0057] like Figure 1 and Figure 2 As shown, a line-reeling mechanism of the first embodiment of the present invention includes a return wheel 33, a first elastic reset member 35 and a limiting body 20. The line 50 is wound around the return wheel 33. The return wheel 33 rotates forwardly under the external force of the line 50 to overcome the elastic force of the first elastic reset member 35.

[0058] In this embodiment, the limiting body 20 has a third position and a fourth position. The external force of the wire 50 drives the return wheel 33 and drives the limiting body 20 through the return wheel 33 so that the limiting body 20 reciprocates between the third position and the fourth position.

[0059] When the limiting body 20 is in the third position, the limiting body 20 cooperates with the return wheel 33 to prevent the return wheel 33 from rotating in the opposite direction; when the limiting body 20 is in the fourth position, the limiting body 20 is separated from the return wheel 33, the return wheel 33 is released from the limit, and the return wheel 33 automatically rotates in the opposite direction and resets under the action of the first elastic reset member 35, and drives the line 50 to automatically reel in. This cycle repeats.

[0060] In this embodiment, the return wheel 33 is rotatably mounted in the return wheel installation box 30, the line 50 extends out of the return wheel installation box 30, the first elastic reset member 35 is arranged in the return wheel installation box 30, the line 50, the return wheel 33, the first elastic reset member 35 and the return wheel installation box 30 are assembled as a whole, the return wheel installation box 30 is slidably mounted in the wire take-up box 10, and the return wheel installation box 30 and the limiting body 20 are both arranged in the accommodating cavity of the return box 10. The limiting body 20 is specifically a limiting slider, and the return wheel 33 drives the limiting body 20 to slide in the return box 10.

[0061] Wherein, the return wheel installation box 30 drives the limiting body 20 under the external force of the line 50 so that the limiting body 20 reciprocates between the third position and the fourth position; Figure 3As shown, the return wheel installation box 30 is provided with a clearance opening 37, and the limiting body 20 and the return wheel 33 are limited and matched via the clearance opening 37. Specifically, the take-up box 10 is provided with a slide rail 13, and the return wheel installation box 30 slides along the slide rail 13; the first elastic reset member 35 is a torsion spring, one end of which is connected to the return wheel 33, and the other end is connected to the return wheel installation box 30. The return wheel installation box 30 can be provided with a slide groove (not shown) that slides with the slide rail 13, or can directly slide with the slide rail 13 through the bottom surface of the return wheel installation box 30.

[0062] like Figure 8 As shown, the outer circumference of the return wheel 33 is provided with a plurality of spaced limiting teeth 34; or, the return wheel 33 adopts a ratchet, and the outer circumference of the ratchet is provided with a plurality of spaced limiting teeth 34; the return wheel 33 is limitedly matched with the limiting body 20 through the limiting teeth 34. Moreover, when the limiting body 20 and the return wheel 33 are limitedly matched, the return wheel 33 is unidirectionally rotated relative to the limiting body 20; that is, the return wheel 33 can rotate forward relative to the limiting body 20, and the limiting body 20 limits the reverse rotation of the return wheel 33; an inclined surface is provided between two adjacent limiting teeth 34 on the return wheel 33, and the inclined surface enables the return wheel 33 to achieve unidirectional rotation when it is limitedly matched with the limiting body 20. When the return wheel 33 rotates, the inclined surface moves against the outer end of the limiting body 20.

[0063] In this embodiment, Figure 2 and Figure 7 As shown, it also includes a first positioning mechanism 40 for positioning the limiting body 20. Each time the return wheel 33 drives the limiting body 20, the first positioning mechanism 40 alternately positions the limiting body 20 at the third position and the fourth position, so that the limiting body 20 reciprocates between the third position and the fourth position. The first positioning mechanism 40 includes a limiting rod 41 of the first positioning mechanism and a limiting body track groove 21 provided on the limiting body 20. The limiting body track groove 21 is provided with a first limiting step 22 of the limiting body and a second limiting step 23 of the limiting body. When the limiting rod 41 of the first positioning mechanism is hooked and engaged with the first limiting step 22 of the limiting body, the limiting body 20 is positioned at the third position. When the limiting rod 41 of the first positioning mechanism is hooked and engaged with the second limiting step 23 of the limiting body, the limiting body 20 is positioned at the fourth position.

[0064] like Figures 9 to 11As shown, in this embodiment, the return wheel 33, the first elastic reset member 35 and the limit body 20 are all installed in the wire take-up box 10. The limit rod 41 of the first positioning mechanism includes a limit end 411 and a mounting end 412, the mounting end 412 is rotatably mounted on the wire take-up box 10, and the limit end 411 slides along the corresponding track groove 21 of the limit body 20. When the track groove 21 drives the limit body 20, the limit end 411 of the limit rod 41 moves in the same direction of the track groove 21.

[0065] Furthermore, a first elastic stopper 431 acting on the stopper 20 is provided between the stopper 20 and the wire take-up box 10, and the first elastic stopper 431 applies an elastic force to the stopper 20 in the direction of the stopper matching with the return wire wheel 33. The first positioning mechanism 40 also includes a second elastic stopper 42 provided between the stopper rod 41 of the first positioning mechanism and the wire take-up box 10, and the second elastic stopper 42 applies an elastic force to the stopper end 411 of the stopper rod 41 of the first positioning mechanism in the direction of the correspondingly matched track groove 21, so that the stopper end 411 of the stopper rod 41 can slide against the bottom surface of the track groove 21 on the stopper 20, thereby ensuring that the stopper end 411 of the stopper rod 41 moves in the same direction of the track groove 21. The second elastic reset member 36 is also included. The return wheel 33 moves toward the limiting body by overcoming the elastic force of the second elastic reset member 36 to drive the limiting body 20 so that the limiting body 20 moves between the third position and the fourth position. After the external force of the line 50 is removed, the second elastic reset member 36 drives the return wheel 33 to reset. The second elastic reset member 36 is specifically elastically pushed between the return wheel installation box 30 and the take-up box 10. In this embodiment, the first elastic limit member 431, the second elastic limit member 42, and the second elastic reset member 36 are all compression springs.

[0066] like Figure 3 , Figure 4 and Fig.10 As shown, when the line 50 is pulled out for the first time, the line 50 drives the return wheel 33 to rotate forward and slide toward the side of the limiting body 20 at the same time. The limiting body 20 overcomes the elastic force of the first elastic limiting member 431 under the push of the return wheel 33 and slides relative to the limiting rod 41. After the external force of pulling the line 50 is released, the return wheel 33 is reset under the action of the second elastic reset member 36, and the limiting body 20 is extended under the action of the first elastic limiting member 431. At this time, the limiting end 411 of the limiting rod 41 is hooked with the first limiting step 22 of the limiting body 20, and the limiting body 20 is in the third position, thereby cooperating with the limiting tooth 34 of the return wheel 33 to prevent the return wheel 33 from rotating in the opposite direction, so that the length of the line 50 pulled out is fixed.

[0067] like Figure 5 , Figure 6 and Fig.11 As shown, when the line 50 is pulled out again, the line 50 drives the return wheel 33 to rotate forward again and slide toward the side of the limiting body 20 at the same time. The limiting body 20 overcomes the elastic force of the first elastic limiting member 431 again under the push of the return wheel 33 and slides relative to the limiting rod 41, and the limiting end 411 of the limiting rod 41 moves along the track groove 21. After releasing the external force of pulling the line 50, the return wheel 33 is reset under the action of the second elastic reset member 36, and the limiting end 411 of the limiting rod 41 is hooked with the second limiting step 23 of the limiting body 20, so that the limiting body 20 retracts to the fourth position, thereby separating from the return wheel 33, and the return wheel 33 is released from the limit. The return wheel 33 rotates in the opposite direction and resets under the torque of the first elastic reset member 35. During the process of the return wheel 33 rotating in the opposite direction and resetting, the line 50 is retracted to the initial length. By pulling the line 50 in this way, the line 50 can be alternately pulled out of the positioning length or retracted to the initial length.

[0068] In this embodiment, it can also be replaced by:

[0069] The return wheel 33 and the return wheel mounting box 30 do not slide, and the return wheel 33 rotates in place under the pull of the line 50. A convex portion (not shown) is provided on the return wheel 33, and the convex portion rotates with the return wheel 33. When the convex portion rotates to cooperate with the limit body 20, the convex portion drives the limit body 20 to slide once, so that the limit body 20 moves alternately between the third position and the fourth position. This is also feasible.

[0070] Second embodiment (return wheel reciprocates, and the limiting body remains stationary):

[0071] A wire-reeling mechanism of a second embodiment of the present invention not shown in the figure is different from the above-mentioned embodiment in that, in this embodiment, the return wheel 33 has a first position and a second position, while the limiting body 20 remains stationary and does not have a third position and a fourth position.

[0072] Specifically, the external force of the line 50 drives the return wheel 33 so that the return wheel 33 reciprocates between the first position and the second position; when the return wheel 33 is in the first position, the limiting body 20 cooperates with the return wheel 33 to prevent the return wheel 33 from rotating in the opposite direction; when the return wheel 33 is in the second position, the limiting body 20 is separated from the return wheel 33, and the return wheel 33 automatically rotates in the opposite direction and resets under the action of the first elastic reset member 35 and drives the line 50 to automatically reel in.

[0073] The return wheel 33 is installed in the return wheel installation box 30, and the return wheel installation box 30 reciprocates between the first position and the second position under the external force of the line 50, so that the return wheel 33 reciprocates between the first position and the second position.

[0074] Correspondingly, in this embodiment, since the limiting body 20 is immovable, the first positioning mechanism 40 and the first elastic limiting member 431 acting on the limiting body 20 are not required, and instead, a second positioning mechanism (not shown) is provided to position the return wheel 33, and the second positioning mechanism is similar to the first positioning mechanism described above. Each time the wire 50 drives the return wheel 33, the second positioning mechanism alternately positions the return wheel 33 at the first position and the second position, so that the return wheel 33 reciprocates between the first position and the second position. Wherein, the second positioning mechanism includes a limiting rod of the second positioning mechanism and a track groove of the return wheel (not shown) provided on the return wheel 33 or on a component (such as the return wheel mounting box 30) assembled with the return wheel 33, and the track groove of the return wheel is provided with a first limiting step of the return wheel and a second limiting step of the return wheel; when the limiting rod of the second positioning mechanism is hooked and engaged with the first limiting step of the return wheel, the return wheel 33 is positioned at the first position, and when the limiting rod of the second positioning mechanism is hooked and engaged with the second limiting step of the return wheel, the return wheel 33 is positioned at the second position. This embodiment also includes a second elastic reset member 36, and the return wheel 33 moves toward the direction of the limiting body 20 by overcoming the elastic force of the second elastic reset member 36, that is, the second elastic reset member 36 applies a force on the return wheel 33 to move away from the limiting body 20.

[0075] As in the first embodiment, in this embodiment, the limiting rod of the second positioning mechanism also includes a limiting end 411 and a mounting end 412, wherein the mounting end 412 is rotatably mounted on the wire take-up box 10, and the limiting end 411 slides along the corresponding track groove of the return wheel. When the return wheel 33 reciprocates between the first position and the second position, the limiting end 411 of the limiting rod 41 moves in the same direction of the track groove 21. The second positioning mechanism also includes a second elastic limiting member 42 disposed between the limiting rod of the second positioning mechanism and the wire take-up box 10, wherein the second elastic limiting member 42 applies an elastic force to the limiting end 411 of the limiting rod of the second positioning mechanism in the direction of the track groove of the corresponding return wheel, so that the limiting end 411 of the limiting rod 41 can slide against the bottom surface of the track groove 21 of the return wheel, thereby ensuring that the limiting end 411 of the limiting rod 41 moves in the same direction of the track groove 21.

[0076] When in use, the line 50 is pulled out for the first time, and the line 50 drives the return wheel 33 to rotate forward and slide toward the side of the limiting body 20 at the same time. The return wheel 33 overcomes the elastic force of the second elastic reset member 36 and slides relative to the limiting rod 41. After the external force of pulling the line 50 is released, the limiting end 411 of the limiting rod 41 hooks with the first limiting step 22 of the return wheel, and the return wheel is in the first position. The limiting teeth 34 of the return wheel 33 are limited by the limiting body 20 and cannot rotate in the opposite direction, so that the length of the line 50 pulled out is fixed.

[0077] When the wire 50 is pulled out again, the wire 50 drives the return wheel 33 to rotate forward again and slide toward the side of the limiting body 20 at the same time. The return wheel 33 overcomes the elastic force of the second elastic reset member 36 again and slides relative to the limit rod 41, and the limit end 411 of the limit rod 41 moves along the track groove 21. After releasing the external force of pulling the wire 50, the return wheel 33 is reset under the action of the second elastic reset member 36, and the limit end 411 of the return wheel 33 is hooked with the second limit step 23 of the limit body 20, and the return wheel 33 is in the second position, thereby separating from the limit body 20. The return wheel 33 is released from the limit and rotates in the opposite direction to reset under the torque of the first elastic reset member 35. During the process of the return wheel 33 rotating in the opposite direction to reset, the wire 50 is retracted to the initial length. By pulling the wire 50 in this way, the wire 50 can be alternately pulled out to the positioning length or retracted to the initial length.

[0078] The other structures of this embodiment are the same as those of the above two embodiments and will not be described again here.

[0079] The third embodiment (the return wheel and the limiting body perform reciprocating motion respectively):

[0080] A third embodiment of the present invention, not shown in the figure, is a line-retracting mechanism, which is a combination of the first embodiment and the second embodiment, that is, the limiting body 20 has a third position and a fourth position, and the return wheel 33 has a first position and a second position, that is, the return wheel 33 and the limiting body 20 reciprocate between their two positions respectively.

[0081] Correspondingly, this embodiment includes the first positioning mechanism 40 for positioning the limiting body 20 at the third position and the fourth position in the first embodiment and the second positioning mechanism for positioning the return wheel 33 at the first position and the second position in the second embodiment.

[0082] The external force of the line 50 drives the return wheel 33 so that the return wheel 33 reciprocates between the first position and the second position, and at the same time, the line 50 drives the limiting body 20 through the return wheel 33 so that the limiting body 20 reciprocates between the third position and the fourth position. When the return wheel is in the first position and the limiting body 20 is in the third position, the limiting body 20 and the return wheel 33 are close to each other so as to cooperate in limiting position to prevent the return wheel 33 from rotating in the opposite direction; when the return wheel 33 is in the second position and the limiting body 20 is in the fourth position, the limiting body 20 is separated (moved away) from the return wheel 33, thereby releasing the limit on the return wheel 33, and the return wheel 33 automatically rotates in the opposite direction and resets under the action of the first elastic reset member 35 and drives the line 50 to automatically reel in.

[0083] The other structures and usage processes of this embodiment are the same as those of the above two embodiments and will not be repeated here.

[0084] In addition, this embodiment also provides a bathroom device, which includes any of the above-mentioned wire collection mechanisms. Figure 12 to Figure 13 As shown, the bathroom equipment is a toilet cover, which includes a cover and a rear shell 70, the rear end of the cover is rotatably attached to the rear shell 70, the wire take-up mechanism is fixedly arranged on the rear shell 70, and the wire 50 led out from the wire take-up mechanism is connected to the cover; in this embodiment, the cover includes an upper cover (not shown in the figure) and a heating seat ring 60, the rear end of the heating seat ring 60 is provided with a first shaft sleeve 61, the rear shell 70 is provided with a second shaft sleeve 71, the second shaft sleeve 71 corresponds to the position of the first shaft sleeve 61, the wire take-up mechanism is fixedly arranged on the rear shell 70, and the wire 50 led out from the wire take-up mechanism passes through the second shaft sleeve 71 and the first shaft sleeve 61 and then is connected to the heating seat ring 60.
