Description

Technical Field

[0001] This invention relates to the field of water supply and drainage technology, and more specifically, to a toilet flush switch, a toilet flush control device, and a toilet. Background Technology

[0002] A toilet is a sanitary facility primarily used for excretion at home or in public places. A toilet's design typically includes a seat, a tank, and a flushing system. The flushing system uses a flush control device to activate the toilet's flushing function, releasing water from the tank into the bowl to flush away waste. The flushing function is primarily activated by pressing a button, which is usually embedded in an opening in the toilet bowl. Typically, the button is located on the toilet tank lid, on the side of the tank, or at the bottom of the toilet. A button located at the bottom of the toilet is a foot-operated flush switch.

[0003] A Chinese utility model patent, CN212534450U, was published on February 12, 2021. The patent describes a foot-kick switch, including a transmission mechanism comprising a fixed shaft, a first leg, and a second leg. The first and second legs rotate relative to the fixed shaft. The first leg is positioned on the movement trajectory of the button, while the second leg is linked to a pull cord. One end of the button is located inside the housing, and the other end is linked to one end of the transmission mechanism. The other end of the transmission mechanism is connected to the pull cord. The transmission mechanism converts the pressing force of the button into a pulling force, which in turn pulls the cord. This foot-kick switch provides convenient control of the toilet, improving the user experience.

[0004] The aforementioned utility model patent uses a transmission mechanism to control the toilet switch. Because the transmission mechanism activates the extension and retraction of the pull cord by rotating the first and second legs on a fixed axis, the transmission mechanism is relatively large, its structure is not compact, and it is inconvenient for installation, disassembly, and maintenance. Summary of the Invention

[0005] To address the technical problem of excessively large toilet flush switches being difficult to repair, this solution provides a toilet flush switch, a toilet flush control device, and a toilet. The drive component in this solution uses gears to adjust the displacement direction of the rack and pinion assembly, resulting in a more compact structure, smaller size, and easier installation.

[0006] To achieve the above objectives, the technical solution provided by the present invention is as follows: A toilet flush switch, including A housing assembly having an internal cavity; A drive assembly, connected to the inner cavity, includes a gear and a rack assembly meshing with the gear. The gear adjusts the displacement direction of the rack assembly to pull a rope connected to the rack assembly to extend or retract.

[0007] During use, pressing the toilet button triggers a series of actions: the button's pressure moves one end of a rack assembly along the direction of pressure. The gears alter the rack assembly's direction of movement, ensuring it aligns with the toilet button's movement, thus pulling the connected cord. This gear-driven design allows for a reduction in the drive assembly's lateral dimensions without interfering with the cord's extension and retraction. The drive assembly's width can be set smaller than the opening size of the toilet button, facilitating installation and removal, and simplifying maintenance and repair.

[0008] In a toilet flush switch provided in this application, the rack assembly further includes a driving rack and a driven rack. One end of the pull cord is fixed to the driven rack. The driving rack and the driven rack are staggered and meshed on both sides of the gear, so that the driving rack and the driven rack move synchronously in opposite directions. When the driving rack is subjected to force, it moves along the length of the rack assembly, while the driven rack moves in the opposite direction under gear adjustment. The driven rack then drives the pull cord to extend or retract, so that the rack assembly remains consistent with the movement direction of the toilet button.

[0009] In a toilet flush switch provided in this application, the active rack further includes a first slider and a drive arm with one end fixed to the first slider. The other end of the drive arm passes through the housing assembly and extends outside the housing assembly. When the drive arm is subjected to force, it drives the first slider to move along the length direction of the housing assembly. The drive arm, as the force-bearing end, extends outside the housing assembly at one end, which facilitates the force it receives.

[0010] In a toilet flush switch provided in this application, the first slider further includes a first tooth facing the gear, the first tooth meshing with the gear; the upper and lower ends of the first slider are respectively provided with first sliding grooves, the first sliding grooves being connected to the housing assembly, so that the first slider can move along the length direction of the housing assembly. The presence of first sliding grooves at both the upper and lower ends of the first slider increases the stability of the first slider sliding within the housing assembly.

[0011] In a toilet flush switch provided in this application, the drive arm further includes a first arm, one end of which is fixedly connected to the end of the first slider, and the other end passes through the housing assembly and extends to the outside of the housing assembly.

[0012] In a toilet flush switch provided in this application, the drive arm further includes a reinforcing member connected to the first support arm to enhance its strength. The first support arm, as a direct stress point, is prone to damage due to excessive or uneven stress. The reinforcing member improves the strength of the first support arm and extends its service life.

[0013] In a toilet flush switch provided in this application, the reinforcing member further includes a slide rod with one end connected to a first support arm. One end of the slide rod passes through the end of the housing assembly and extends into the housing assembly. The slide rod can change the stress point of the first support arm, reducing its bending moment and lowering the risk of breakage under stress.

[0014] In a toilet flush switch provided in this application, the slide rod has a cross-section in the shape of a cross. The cross-section of the cross can simultaneously improve the lateral and longitudinal strength of the slide rod, reducing the risk of breakage due to uneven stress.

[0015] In a toilet flush switch provided in this application, the reinforcing member further includes a triangular reinforcing block connected to the first support arm. Adding the triangular reinforcing block directly to the side of the first support arm makes it easier to integrally process and mold, reducing production costs.

[0016] In a toilet flush switch provided in this application, the driven rack includes a second slider and a fixed rope portion connected to one end of the second slider, the fixed rope portion being fixed to one end of the pull rope.

[0017] In a toilet flush switch provided in this application, a maintenance port is further provided on the housing assembly opposite the rope fixing part, and a flip cover is detachably connected to the maintenance port. In use, the pull rope can be easily and quickly installed simply by opening the flip cover.

[0018] In a toilet flush switch provided in this application, the second slider is provided with a second tooth on the side facing the gear, the second tooth meshing with the gear, and the upper and lower ends of the second slider are respectively provided with second sliding grooves, the second sliding grooves being connected to the housing assembly so that the second slider can move along the length direction of the housing assembly.

[0019] In a toilet flush switch provided in this application, the rope securing part has a cylindrical protrusion and a through groove at the center of the protrusion. A rope groove communicating with the through groove is provided on the side wall of the protrusion, and the opening of the rope groove extends through the end of the protrusion. In use, the end of the pull rope can be directly installed into the through groove of the protrusion through the opening of the rope groove, making installation convenient and quick.

[0020] In a toilet flush switch provided in this application, the housing assembly is fitted into an opening in the toilet. The housing assembly is elongated, and its maximum outer contour size is not greater than the size of the opening. Because the housing assembly is elongated and its maximum outer contour size is not greater than the size of the opening, it can be directly disassembled for inspection and maintenance.

[0021] In a toilet flush switch provided in this application, the housing assembly further includes an upper housing and a lower housing, which together form the inner cavity. A first shaft is fixedly connected in the inner cavity, and the gear is rotatably connected to the first shaft.

[0022] In a toilet flush switch provided in this application, a support body is further connected to the exterior of the upper shell and the lower shell. The support body includes two semi-circular and parallel circular plates, with at least one vertical plate vertically connected between the two circular plates. The height of the vertical plate is flush with the outer perimeter of the circular plates. The support body can strengthen the upper and lower shells and prevent them from twisting and deforming under stress.

[0023] In a toilet flush switch provided in this application, a first track and a second track are further provided on both sides of the inner cavity along its length direction. Each of the first and second tracks includes an upper track and a lower track. The upper track is fixed to the upper shell, and the lower track is fixed to the lower shell. The upper and lower tracks are arranged opposite to each other to form a gap for the rack assembly to slide within the inner space. Since the first or second slider has first and second teeth arranged on its side, it needs to mesh with gears. Therefore, the first and second tracks ensure stable sliding of the slider in a specified direction without interfering with gear transmission.

[0024] In a toilet flush switch provided in this application, a limiter is further fixed to the tail of the driving rack and the driven rack. The limiter restricts the movement distance of the driving rack and the driven rack within the inner cavity, preventing them from disengaging from the track.

[0025] In a toilet flush switch provided in this application, an external component is further included. This external component has a fixing sleeve and a button. The fixing sleeve is fitted over the housing assembly to fix the housing assembly inside the toilet opening. The button is fitted onto the rack assembly. The external component connects the housing assembly and the toilet opening, allowing the housing assembly to be easily and quickly removed from the toilet for replacement and maintenance.

[0026] In a toilet flush switch provided in this application, the fixed sleeve includes a cylindrical column and retaining rings and a flat opening respectively connected to both ends of the column. The outer periphery of the column is provided with external threads for threaded connection with the opening. The inner wall of the flat opening is provided with a support column, which is supported on the outer wall of the housing assembly.

[0027] In a toilet flush switch provided in this application, a return spring is further included. The return spring is fitted inside or outside the housing assembly to support the rack assembly in resetting after sliding under force. The return spring can be installed at any position in the entire drive assembly, and only needs to reset it after the rack assembly has been displaced.

[0028] In a toilet flush switch provided in this application, the toilet flush switch is further described as a foot-kick switch, which is fixed to the side of the bottom of the toilet. The foot-kick switch makes it more convenient to use the toilet flush switch and avoids getting your hands dirty.

[0029] In a toilet flush switch provided in this application, the rack assembly further includes a drive rack, a thin rope, and a pulley. The drive rack meshes with the gear. The pulley is coaxially fixedly connected to the end of the gear. The pulley rotates with the gear, causing the thin rope wound around it and the pull cord connected to one end of the thin rope to extend and retract. During operation, the drive rack drives the gear to rotate, and the gear synchronously drives the pulley to rotate. The thin rope then winds around the pulley, pulling the pull cord to retract and complete the toilet flush.

[0030] This application provides a toilet flushing control device, including... Toilet flush switch; A flushing device, which is connected to the toilet flush switch via a pull cord.

[0031] In a toilet flushing control device provided in this application, the flusher further includes a main body and a button, the button being used to open the flushing valve on the main body; The pull cord includes a core and a loop wrapped around the core. The end of the loop, away from the toilet flush switch, is fixed to the button. After fixing the loop to the button, the core can be fixed to any suitable position, either on the main body or elsewhere. When the core is pulled and retracted, the loop at the button's end displaces from the core, shortening the distance between their ends. Since the core end is fixed, the loop can pull the button, causing it to press and initiate a flush, achieving a loop-push button effect. This loop-push button technology utilizes the button's inherent function to achieve flushing, resulting in a more stable flushing structure and greater selectivity in flushing methods.

[0032] In a toilet flushing control device provided in this application, the flusher further includes a main body and a button. The button is used to open the flush valve on the main body. The button is provided with a spring-loaded cover, which, when subjected to force, drives the button to move downward. The spring-loaded cover can push the button downward after being subjected to force, thus also achieving the flushing operation. In the event of a malfunction of the toilet flush switch, flushing can be achieved using the spring-loaded cover and the button in conjunction, without affecting the normal use of the toilet.

[0033] A toilet, wherein the toilet flush switch is provided.

[0034] In a toilet provided in this application, further including A flushing device, which is connected to the toilet flushing switch via a pull cord, has a main body and a button, the button being used to open the flushing valve on the main body; The pull cord includes a core and a loop wrapped around the core, with the end of the loop away from the toilet flush switch fixed to the button.

[0035] Compared with the prior art, the technical solution provided by this invention has the following advantages: In the toilet flush switch provided by this invention, pressing the toilet button triggers a series of actions during use: the button press pushes one end of a rack assembly to move along the pressing direction. The movement direction of the rack assembly can be changed through the action of gears, keeping it aligned with the movement direction of the toilet button, thereby pulling the connected pull cord. This design, which adjusts the movement direction of the rack assembly through gears, allows for a reduction in the lateral dimension of the drive assembly without interfering with the extension and retraction of the pull cord. The width of the drive assembly can be set to be smaller than the opening size of the toilet button, facilitating installation and removal from the opening, and simplifying maintenance and repair.

[0036] (2) This application provides a toilet flushing control device, wherein the flusher has a main body and a button, the button being used to open the flushing valve on the main body; the pull cord includes a core and a loop wrapped around the core, the end of the loop away from the toilet flushing switch being fixed to the button. After the loop is fixed to the button, the core can be fixed at any suitable position on or outside the main body. When the core is pulled and contracted, the loop fixed to the button and the core are displaced, shortening the distance between their ends. Since the end of the core is fixed, the loop can pull the button, causing the button to be pressed to perform a flushing operation, achieving the effect of the loop pushing the button. The loop pushing button technology can utilize the button's own function to achieve the flushing operation, making the flushing structure more stable and providing more choices for the flushing method.

[0040] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. Example 1

[0041] like Figure 1-2 As shown, the present invention provides a toilet flush switch, including a housing assembly 100 having an inner cavity 110. A drive assembly 200 is connected to the inner cavity 110, and includes a gear 210 and a rack assembly 220 meshing with the gear 210. The gear 210 adjusts the displacement direction of the rack assembly 220 to pull a pull cord 600 connected to the rack assembly 220 to extend or retract.

[0042] During use, pressing the toilet button 320 triggers a series of actions: the pressure of the button 320 pushes one end of the rack assembly 220 to move in the pressing direction. The gear 210 changes the direction of movement of the rack assembly 220, ensuring it aligns with the direction of movement of the toilet button 320, thereby pulling the connected pull cord 600. This design, using the gear 210 to adjust the direction of movement of the rack assembly 220, allows for a reduction in the lateral dimension of the drive assembly 200 without interfering with the extension and retraction of the pull cord 600. The width of the drive assembly 200 can then be set smaller than the opening size of the toilet button 320, facilitating installation and removal through the opening and simplifying maintenance and repair.

[0043] Housing assembly 100 The housing assembly 100 is fixed within an opening (not shown) on the toilet, and the resulting inner cavity 110 is used to connect the drive assembly 200. The housing assembly 100 is elongated, and its maximum outer contour dimension is no larger than the opening size. Because the housing assembly 100 is elongated and its maximum outer contour dimension is no larger than the opening size, it can be directly disassembled for inspection and maintenance.

[0044] like Figure 3 and Figure 6 As shown, specifically, the housing assembly 100 includes an upper shell 140 and a lower shell 150, which together form a housing assembly 100 structure having an internal cavity 110. The upper shell 140 and the lower shell 150 are detachably connected by snaps or screws.

[0045] like Figure 2 As shown, a support body 170 is connected to one end of the housing assembly 100. The support body 170 includes two semi-circular, parallel circular plates 171, which are vertically connected to the housing assembly 100. At least one vertical plate 172 is vertically connected between the two circular plates 171, and the height of the vertical plate 172 is flush with the outer periphery of the circular plates 171. A support body 170 is connected to both the upper shell 140 and the lower shell 150, and the support bodies 170 connected to the upper shell 140 and the lower shell 150 are arranged opposite to each other. The support body 170 can strengthen the upper shell 140 and the lower shell 150, preventing them from twisting and deforming under stress.

[0046] like Figure 6 As shown, a first shaft post 160 is fixed inside the cavity 110 of the housing assembly 100. One end of the first shaft post 160 is fixed to the end face of the upper shell 140 or the lower shell 150 and is perpendicular to the upper shell 140 or the lower shell 150.

[0047] like Figure 6 As shown, the housing assembly 100 has a first track 181 and a second track 182 on both sides along its length. Both the first track 181 and the second track 182 include an upper track and a lower track. The upper track is fixed to the upper shell 140, and the lower track is fixed to the lower shell 150. The upper and lower tracks are arranged opposite each other, with a gap between them. Since the first slider 2211 or the second slider 2221 has a first tooth 2213 and a second tooth 2223 arranged on its side, it needs to mesh with the gear 210. Therefore, the first track 181 and the second track 182 are provided to ensure stable sliding of the slider in a specified direction without interfering with the gear 210 transmission.

[0048] like Figure 6As shown, limiters 190 are fixed to the tails of the driving rack 221 and the driven rack 222, limiting the movement distance of the driving rack 221 and the driven rack 222 within the inner cavity 110. The limiter 190 can be a stop fixed to the housing assembly 100 or other structures that limit the movement distance of the driving rack 221 or the driven rack 222. Driver Component 200

[0049] like Figure 3-5 As shown, the drive assembly 200 includes a gear 210 and a rack assembly 220. The gear 210 is rotatably connected to the first shaft 160, and the rack assembly 220 is connected to the side of the gear 210. The rack assembly 220 includes a driving rack 221 and a driven rack 222. The driving rack 221 is slidably connected to the first track 181 and slides along the length of the first track 181. The driving rack 221 meshes with the side of the gear 210, and when the driving rack 221 slides on the first track, it drives the gear 210 to rotate. The driven rack 222 is slidably connected to the second track 182 and slides along the length of the second track 182. The driven rack 222 meshes with the other side of the gear 210, and when the gear 210 rotates, it drives the driven rack 222 to slide on the second track. The driving rack 221 and the driven rack 222 are connected in a staggered manner on both sides of the gear 210, so that the driving rack 221 and the driven rack 222 can move in opposite directions along the length of the housing assembly 100 in the inner cavity 110.

[0050] like Figure 4 As shown, the active rack 221 includes a first slider 2211 and a drive arm 2212 with one end fixed to the first slider 2211. The other end of the drive arm 2212 passes through the housing assembly 100 and extends outside the housing assembly 100. When the drive arm 2212 is subjected to force, it drives the first slider 2211 to move along the length direction of the housing assembly 100. The drive arm 2212 serves as the force-bearing end, with one end extending outside the housing assembly 100, which facilitates the force it receives.

[0051] The first slider 2211 includes a first tooth 2213 on its side, which faces and meshes with the gear 210. The first slider 2211 has first grooves 2214 at its upper and lower ends, the size of which is adapted to the first guide rail. The presence of first grooves 2214 at both ends of the first slider 2211 increases the stability of its sliding within the housing assembly 100. Specifically, the upper half of the first track 181 engages in the first groove 2214 at the top of the first slider 2211, and the lower half engages in the first groove 2214 at the bottom of the first slider 2211. The upper and lower halves of the first track 181 engage the first slider 2211 within the gap between them, making the sliding of the first slider 2211 more stable and smooth.

[0052] like Figure 4 As shown, the drive arm 2212 includes a first arm 2215, one end of which is fixedly connected to the end of the first slider 2211, and the other end passes through the housing assembly 100 and extends to the outside of the housing assembly 100. The cross-sectional shape of the first arm 2215 is adapted to the shape of the first connecting hole opened at the end of the housing assembly 100.

[0053] The drive arm 2212 includes a reinforcing member 223, which is connected to the first support arm 2215 to strengthen the first support arm 2215. The first support arm 2215, as a direct load-bearing point, is prone to damage due to excessive or uneven stress. The reinforcing member 223 improves the strength of the first support arm 2215 and extends its service life.

[0054] like Figure 4 As shown, the reinforcing member 223 can be a slide rod 2231 with one end connected to the first support arm 2215. One end of the slide rod 2231 passes through the end of the housing assembly 100 and extends into the housing assembly 100. The slide rod 2231 can change the stress point of the first support arm 2215, reduce its bending moment, and lower its risk of breakage under stress. The cross-sectional shape of the slide rod 2231 is adapted to the shape of the second connecting hole opened at the end of the housing assembly 100. The cross-sectional shape of the slide rod 2231 can be circular or rectangular. Preferably, the cross-sectional shape of the slide rod 2231 is cross-shaped. The cross-shaped cross-section can simultaneously improve the lateral and longitudinal strength of the slide rod 2231, reducing the risk of breakage due to uneven stress on the slide rod 2231.

[0055] like Figure 5 As shown, the driven rack 222 includes a second slider 2221 and a rope-fixing portion 2222 connected to one end of the second slider 2221. The second slider 2221 includes a second tooth 2223 on its side, which faces and meshes with the gear 210. The top and bottom of the second slider 2221 are respectively provided with second grooves 2224, the size of which is adapted to the second guide rail. Specifically, the upper half of the second track 182 engages in the second groove 2224 at the top of the second slider 2221, and the lower half engages in the second groove 2224 at the bottom of the second slider 2221. The upper and lower half of the second track 182 engage the second slider 2221 in the gap between the upper and lower half of the track, making the sliding of the second slider 2221 more stable and smooth.

[0056] like Figure 5As shown, the rope securing part 2222 includes a cylindrical protrusion 2225, with a through groove 2226 at its center. A rope groove 2227, communicating with the through groove 2226, is formed on the side wall of the protrusion 2225, passing through the end of the protrusion 2225. In use, the end of the pull rope 600 can be directly installed into the through groove 2226 of the protrusion 2225 through the opening of the rope groove 2227, making installation convenient and quick.

[0057] A return spring (not shown in the figure) is fitted inside or outside the housing assembly 100 to support the rack assembly 220 in resetting after sliding under force. Specifically, the return spring can be fitted onto the slide rod 2231, with one end pressing against the end of the drive arm 2212 and the other end pressing against the outer end of the housing assembly 100. The return spring can also be located between the toilet button 320 and the outer end of the housing assembly 100. There are no specific restrictions on the installation position of the return spring; it can be installed at any position in the entire drive assembly 200, as long as it can reset the rack assembly 220 after displacement.

[0058] External component 300 The external component 300 connects the housing assembly 100 to the toilet opening, allowing the housing assembly 100 to be easily and quickly removed from the toilet for replacement and repair.

[0059] like Figure 7 As shown, the external assembly 300 includes a fixing sleeve 310 and a button 320. The fixing sleeve 310 is used to fix the housing assembly 100 and the drive assembly 200 to the opening of the toilet. The fixing sleeve 310 includes a cylindrical column 311 with an external thread 314 on its outer periphery, which can be threaded into the opening of the toilet. A retaining ring 312 is fixedly connected to one end of the column 311, and a square flat opening 313 is fixedly connected to the other end. The housing assembly 100 is fitted inside the column 311, with one end protruding from the flat opening 313 and the other end protruding from the retaining ring 312. A support post (not shown in the figure) is provided on the inner wall of the flat opening 313, and the support post supports the outer wall of the housing assembly 100. The support post can reduce the contact area between the fixing sleeve 310 and the housing assembly 100 when fixing the housing assembly 100, making it easier for the housing assembly 100 to be pulled out from the fixing sleeve 310.

[0060] The toilet button 320 is typically a cylindrical housing assembly 100, with an integrally formed arc-shaped end cap at one end. The end cap has a recess inside for engaging the end of the drive arm 2212. The button 320 can push the drive arm 2212, thereby moving the entire drive rack 221.

[0061] The toilet flush switch is a foot-operated switch, which is fixed to the side of the bottom of the toilet. The foot-operated switch makes it more convenient to use the toilet flush switch and keeps your hands clean.

[0062] Example 2 like Figure 8 As shown, based on Embodiment 1, the reinforcing member 223 includes a triangular reinforcing block 2232 connected to the first support arm 2215. An opening adapted to the triangular reinforcing block 2232 is provided at the end of the housing assembly 100, allowing the first rack to provide support when sliding into the housing assembly 100. The triangular reinforcing block 2232 effectively improves the overall structural strength of the drive arm 2212, making it less prone to breakage under stress. Furthermore, adding the triangular reinforcing block 2232 to the side of the first support arm 2215 makes it easier to integrally machine the two components, reducing production costs.

[0063] Example 3 Based on Embodiment 1, the driven rack 222 is eliminated. The rack assembly 220 includes a driving rack 221, a thin rope, and a pulley. The driving rack 220 meshes with the gear 210. The pulley is coaxially fixedly connected to the end of the gear 210. The pulley rotates with the gear 210, causing the thin rope wound around it and the pull rope 600 connected to one end of the thin rope to extend and retract. During operation, the driving rack 221 drives the gear 210 to rotate, and the gear 210 synchronously drives the pulley to rotate. The thin rope then winds around the pulley, pulling the pull rope 600 to retract and complete the toilet flushing.

[0064] Example 4 like Figure 3 As shown, to facilitate the installation of the pull rope 600, an inspection port 120 is provided on the housing assembly 100, with the inspection port 120 positioned directly opposite the rope fixing part 2222 at the end of the driven rack 222. A flip cover 130 is snapped or slidably connected to the installation port. In use, simply opening the flip cover 130 allows for convenient and quick installation of the pull rope 600.

[0065] Example 5 like Figure 9As shown, this application provides a toilet flushing control device, including a toilet flushing switch and a flusher 500, which is connected to the toilet flushing switch via a pull cord 600. The flusher 500 is normally installed inside the toilet tank and has a flushing valve that controls the flow of water to the toilet bowl. The flusher 500 is a prior art device, and its specific structure will not be described in detail. In the toilet flushing control device provided in this application, the flusher 500 further includes a main body 510 and a button 520, which is used to open the flushing valve on the main body 510; the pull cord 600 includes a cord core 610 and a cord sleeve 620 wrapped around the cord core 610, with the end of the cord sleeve 620 away from the toilet flushing switch fixed to the button 520. After securing the loop 620 to the button 520, the rope core 610 can be fixed to the main body 510 or any suitable position outside the main body 510. When the rope core 610 is pulled and retracted, the loop 620 fixed to one end of the button 520 and the rope core 610 are displaced, shortening the distance between their ends. Since the end of the rope core 610 is fixed, the loop 620 can pull the button 520, causing the button 520 to be pressed and initiate a flushing operation, achieving the effect of the loop 620 pushing the button 520. This loop 620 pushing the button 520 technology utilizes the button 520's own function to achieve a flushing operation, resulting in a more stable flushing structure and providing more choices in flushing methods.

[0066] The flushing device 500 has a main body 510 and a button 520. The button 520 is used to open the flush valve on the main body 510. The button 520 is equipped with a spring-loaded cover (not shown in the figure). When the spring-loaded cover is subjected to force, it drives the button to move downward. The spring-loaded cover can push the button downward after being subjected to force, which can also realize the flushing operation. In the event that the toilet flush switch is damaged, the spring-loaded cover and the button 520 can be used together to flush without affecting its use.

[0067] Based on this, this application provides a toilet, which includes a toilet flush switch or a toilet flush control device.

[0068] Specifically, the toilet includes a flushing device 500, which is connected to the toilet flush switch via a pull cord 600. The flushing device 500 has a main body 510 and a button 520, which is used to activate the flush valve on the main body 510. The pull cord 600 includes a cord core 610 and a cord sleeve 620 wrapped around the cord core 610. The end of the cord sleeve 620 away from the toilet flush switch is fixed to the button 520.
