Description

Technical Field

[0001] The present application relates to the technical field of smart toilets, and in particular to a wire-controlled drainage switch. Background Art

[0002] A smart toilet is a bathroom device that integrates modern technology with traditional toilet functions, providing users with a more convenient, comfortable and hygienic experience.

[0003] Smart toilets are usually equipped with backup batteries to ensure that they can still flush normally in the event of a power outage. They are usually built into the control box of the smart toilet. When the main power is cut off, the backup battery will automatically take over the power supply to ensure the normal use of the smart toilet. When the smart toilet is used less frequently, the backup battery is sufficient to support the normal use of the smart toilet until the main power is restored; however, if the power of the backup battery is consumed to a certain extent, the solenoid valve will not be opened and closed to complete the flushing action, which limits the normal use of the smart toilet in the event of a power outage.

[0004] The existing Chinese utility model patent with publication number CN219909210U discloses a wire-controlled drainage switch, including: a pull rope, a connector, a spring mechanism and a handle, the handle is connected to the first end of the spring mechanism, the second end of the spring mechanism is connected to the first end of the connector, the second end of the connector is connected to the first end of the pull rope, the second end of the pull rope is used to connect to the drainage valve, and the drainage valve can be controlled to open for flushing by pulling the handle outward. The utility model patent has a simple structure and labor-saving operation, and can realize manual flushing when the smart toilet is powered off, and the number of uses is not limited.

[0005] However, since the pull rope is immersed in water for a long time and will be pulled during use, the rope loop on its surface that protects it is easily damaged by water erosion, bending and deformation after long-term use. In addition to being pulled, the pull rope is also easily affected by water erosion, and may even break, resulting in the wire-controlled drainage switch being unable to continue to be used.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-6 This application is described in further detail.

[0047] Embodiment 1:

[0048] Reference Figure 1 The embodiment of the present application discloses a wire-controlled drain switch, which is applied to a smart toilet and installed on a water tank of the smart toilet. When the smart toilet cannot flush normally due to a power failure of the main power supply and the backup power supply is exhausted, the wire-controlled drain switch can be used to control the opening and closing of the drain valve 7 to realize the flushing function of the smart toilet.

[0049] Reference Figure 2 and Figure 3 The wire-controlled drain switch includes a pull cord 1, a connector 2, a bouncing mechanism 3, a handle 4 and a housing 5. The handle 4 is connected to one end of the bouncing mechanism 3, the other end of the bouncing mechanism 3 is connected to one end of the connector 2, the other end of the connector 2 is connected to one end of the pull cord 1, and the other end of the pull cord 1 is used to connect the drain valve 7; the housing 5 is convenient for the wire-controlled drain switch to be installed on the water tank of the smart toilet, the connector 2 and the bouncing mechanism 3 are integrally installed inside the housing 5, and the handle 4 is partially located inside the housing 5 and its end away from the bouncing mechanism 3 is located outside the housing 5.

[0050] When in use, the wire-controlled drain switch is installed in the water tank of the smart toilet. After pressing the handle 4 in the direction close to the bouncing mechanism 3, the bouncing mechanism 3 will extend and pop out the handle 4. At this time, the handle 4 can be pulled outward, and the handle 4 drives the pull rope 1 to pull the drain valve 7 so that the drain valve 7 is opened to flush. After the wire-controlled drain switch is used, press the handle 4 again, the bouncing mechanism 3 will shorten and the handle 4 will be reset. Repeat the previous operation when it is needed next time.

[0051] In this embodiment, the pull rope 1, the connecting part 2, the bouncing movement 3, the handle 4 and the shell 5 are preferably the same as the structures disclosed in the patent document with application number CN202321470271.4, and the patent name is a wire-controlled drainage switch, automatic flushing device for toilet, toilet cover and toilet; since the above structures are all prior arts in this field, they are not described in detail here, and the above structures are only briefly represented in the drawings.

[0052] Reference Figure 3 and Figure 4 The wire-controlled drainage switch also includes a protective pipe 6 for protecting the pull rope 1. The protective pipe 6 is sleeved outside the pull rope 1 and can separate the pull rope 1 from the water in the smart toilet tank to reduce the impact of water erosion on the pull rope 1 and extend the service life of the pull rope 1, thereby effectively improving the stability of normal use of the wire-controlled drainage switch.

[0053] The protective pipe 6 includes a plurality of hoses 61 and two connecting components 62. The protective pipe 6 mainly protects the pull rope 1 through the plurality of hoses 61; the connecting component 62 is used to connect the protective pipe 6 with the connecting component 2 and the drain valve 7.

[0054] Reference Figure 4 and Figure 5 The hose 61 is in a cylindrical structure as a whole, and has a certain elastic deformation capability. In this embodiment, the hose 61 is preferably made of a rubber material with a waterproof effect.

[0055] The multiple hoses 61 can be connected end to end to form an integrated pipe section, and the hoses 61 are detachably connected to each other. The hose 61 includes a pipe body 611 , two clamping parts 612 and two locking parts 614 .

[0056] The tube body 611 is a cylindrical structure obtained by extending a circular ring along an arc trajectory. At this time, the outer surface and the inner surface of the tube body 611 have arc-shaped concave surfaces and arc-shaped convex surfaces of the same size, and when the outer side of the tube body 611 is an arc-shaped concave surface at the same position, the inner side is an arc-shaped convex surface. It is convenient for the tube body 611 to bend and deform after being subjected to force, and effectively improves the adaptability of the tube body 611 to bending and deformation. The minimum inner diameter size of the tube body 611 under normal conditions is not less than the radial size of the pull rope 1. In this embodiment, it is preferred that the minimum inner diameter size of the tube body 611 under normal conditions is equal to the radial size of the pull rope 1.

[0057] The two clamping parts 612 are respectively located at the two ends of the axial direction of the tube body 611. The clamping parts 612 are annular in structure as a whole. The two clamping parts 612 are respectively located at the inner side and the outer side of the tube body 611, and the two clamping parts 612 are aligned along the axial direction of the tube body 611. A clamping groove 613 matching with the clamping part 612 is formed between the clamping part 612 located at the inner side of the tube body 611 and the inner side surface of the tube body 611, and a clamping groove 613 matching with the clamping part 612 is also formed between the clamping part 612 located at the outer side of the tube body 611 and the outer side surface of the tube body 611. When the two hoses 61 are connected end to end, the adjacent clamping parts 612 on the two hoses 61 will be respectively clamped and matched with the adjacent clamping grooves 613 of each other to form a connection.

[0058] The locking portion 614 is also an annular structure as a whole. The two locking portions 614 are respectively located on the two clamping portions 612. The inner side of the locking portion 614 is fixedly connected to the side of the corresponding clamping portion 612 away from the tube body 611. The locking portion 614 is located in the corresponding clamping groove 613, and a locking groove 615 adapted to the positioning portion is formed in the corresponding clamping groove 613 between the locking portion 614 and the corresponding clamping portion 612. When the two hoses 61 are connected end to end, the adjacent locking portions 614 on the two hoses 61 will also be clamped and matched with the adjacent locking grooves 615 of each other, and the two positioning portions will keep in contact with each other. In this embodiment, the radial extension direction of the locking portion 614 is preferably inclined relative to the axial direction of the tube body 611, and is inclined outward along the axial direction of the tube body 611.

[0059] Of the two locking parts 614 on the same hose 61, one locking part 614 has a plurality of positioning blocks 616 on one side surface close to the corresponding locking groove 615, and the plurality of positioning blocks 616 are evenly distributed in a circumferential array on the locking part 614 with the axis of the locking part 614 as the axis; the other locking part 614 has a plurality of positioning grooves 617 adapted to the positioning blocks 616 on one side surface close to the corresponding locking groove 615, and the plurality of positioning grooves 617 are evenly distributed in a circumferential array on the locking part 614 with the axis of the locking part 614 as the axis. When the two hoses 61 are connected end to end, the plurality of positioning blocks 616 on one locking part 614 on one hose 61 can be plugged and matched with the plurality of positioning grooves 617 on the adjacent locking part 614 on the other hose 61. In this embodiment, the positioning blocks 616 are preferably hemispherical in shape.

[0060] At this time, after the two hoses 61 are connected end to end, the two adjacent clamping parts 612, the two locking parts 614, and the several positioning blocks 616 and the several positioning grooves 617 on the two locking parts 614 can all play a waterproof effect between the two hoses 61, so that the gap between the two hoses 61 has sufficient sealing properties.

[0061] Moreover, the two hoses 61 can be connected by simply fitting their ends together, so that the user can choose a suitable number of hoses 61 according to the length of the pull rope 1 and connect them end to end to obtain a pipe section for protecting the pull rope 1, thereby facilitating the user to complete the installation of the protective pipe 6 of the wire-controlled drainage switch.

[0062] Reference Figure 3 and Figure 4 The radial dimension of the inner space of the connecting component 62 is also not less than the radial dimension of the pull rope 1, and the connecting component 62 includes a fixing member 621, a movable member 622 and an elastic member 623. In this embodiment, the radial dimension of the inner space of the connecting component 62 is preferably greater than the radial dimension of the pull rope 1.

[0063] The fixed part 621 and the movable part 622 are both cylindrical structures as a whole. One end of the movable part 622 in the axial direction is located inside the fixed part 621 and is movably connected to the fixed part 621. The moving direction of the movable part 622 is parallel to the axis of the fixed part 621, and the axis of the movable part 622 remains coincident with the axis of the fixed part 621 during the movement.

[0064] The elastic member 623 is installed inside the fixed member 621, and the two ends of the elastic member 623 are respectively fixedly connected to the fixed member 621 and the movable member 622, and the elastic member 623 has a tendency to drive the movable member 622 to move to the extreme position in the direction close to the fixed member 621. In this embodiment, the elastic member 623 is preferably a tension spring.

[0065] In the two connecting components 62, the ends of the two fixing members 621 away from the corresponding movable members 622 are respectively fixedly connected to the ends of the connecting member 2 away from the bouncing mechanism 3 and the drain valve 7, and the ends of the two movable members 622 away from the corresponding fixing members 621 are respectively fixedly connected to the two ends of the integrated pipe section formed by connecting multiple hoses 61 end to end. In this embodiment, preferably, during the use of the wire-controlled drain switch, there is a margin of movement between the movable member 622 and the corresponding fixing member 621, and at this time, the integrated pipe section formed by connecting multiple hoses 61 end to end is kept in a stretched and taut state under the action of the two elastic members 623. In this embodiment, preferably, on the two hoses 61 at both ends of the pipe section, the ends thereof fixedly connected to the movable member 622 do not have structures such as the clamping portion 612 and the locking portion 614.

[0066] When the integrated pipe section formed by connecting multiple hoses 61 end to end is kept in a stretched and taut state, the connection stability between two adjacent hoses 61 is higher, so that the sealing between two adjacent hoses 61 is better; at the same time, the deformation and wear of part of the hose 61 caused by the bending deformation of the pipe section will be reduced, thereby reducing the probability of excessive bending on part of the hose 61 and causing damage to the hose 61 when the pipe section is bent and deformed.

[0067] When the pull cord 1 breaks due to pulling during the use of the online drain switch, the online drain switch can still be used normally. After the user pulls the handle 4, he can still pull the drain valve 7 open through the connecting pipe to complete the flushing, thereby improving the stability of the online drain switch in achieving the flushing effect.

[0068] The implementation principle of a wire-controlled drainage switch in the embodiment of the present application is:

[0069] When the smart toilet cannot flush normally because the main power supply is cut off and the backup power supply is exhausted, the user controls the handle 4 to pop out and pull the handle 4 to control the drain valve 7 to open through the pull cord 1 to complete the flushing;

[0070] During the use of the wire-controlled drainage switch, the protective pipe 6 can maintain the protection of the pull rope 1, so that the pull rope 1 is separated from the water in the smart toilet tank, thereby reducing the probability of the pull rope 1 being corroded by water, and thus the wire-controlled drainage switch can be stably provided for manual flushing by the user for a long time;

[0071] When the pull cord 1 breaks due to pulling or other reasons, the handle 4 can still be connected to the drain valve 7 through the protective pipe 6. The user can still control the drain valve 7 to open and complete flushing through the protective pipe 6 in a short period of time; after the main power supply or backup power supply of the smart toilet is restored, the user can repair or replace the wire-controlled drain switch.

[0072] Embodiment 2:

[0073] Reference Figure 3 and Figure 6 The difference between this embodiment and embodiment 1 lies in the hose 61.

[0074] In order to facilitate the user to connect multiple hoses 61 end to end to form an integrated pipe section, the outer surface of the tube body 611 is preferably evenly distributed with convex grooves 618 to increase the friction between the hand and the outer surface of the tube body 611, so as to facilitate the user to control one hose 61 to rotate relative to the other hose 61 after fitting the ends of the two hoses 61 so that the multiple positioning blocks 616 are respectively plugged into and fitted with the multiple positioning grooves 617.

[0075] Furthermore, during the use of the wire-controlled drain switch, when flushing is not required, the pull cord 1 will be in a vertical or nearly vertical state in the water tank for a long time; when flushing is required, the pull cord 1 will be bent and deformed after being pulled, but the overall state is also relatively close to the vertical state.

[0076] Therefore, the integrated pipe section formed by connecting multiple hoses 61 end to end will be in a vertical or nearly vertical state for a long time in the water tank. During the flushing process, the force of the water flow on the surface of the hose 61 is intensified, which aggravates the wear of the hose 61. In order to reduce the wear of the hose 61 during the flushing process, the convex groove 618 is preferably extended on the outer surface of the tube body 611 along the arc extension trajectory of the tube body 611.

[0077] The implementation principle of a wire-controlled drainage switch in the embodiment of the present application is:

[0078] During the flushing process, the convex groove 618 can guide the water flow, allowing the water flow to pass quickly from the outside of the hose 61; at the same time, it can effectively reduce the impact force of the water flow on the convex groove 618, thereby effectively reducing the probability of the water flow causing wear on the surface of the tube body 611 and the convex groove 618.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
