Description

Technical Field

[0001] The present invention relates to the technical field of water supply and drainage, and more specifically, to a toilet flushing switch, a toilet flushing control device, and a toilet. Background Art

[0002] A toilet is a sanitary facility mainly used for people to excrete at home or in public places. The design of a toilet usually includes a seat ring, a water tank, and a drainage system. In the drainage system, the flushing function of the toilet is controlled by a toilet flushing control device to discharge the water in the water tank into the toilet bowl to flush away the dirt. The drainage function is mainly activated by pressing a button, and these buttons are usually embedded in the openings of the toilet. Usually, the button installation position is on the toilet tank lid, the side of the water tank, or the bottom of the toilet. The button located at the bottom of the toilet is a foot-kick toilet flushing switch.

[0003] A Chinese utility model patent disclosed a foot-kick switch on February 12, 2021, with the publication number CN212534450U, which includes a transmission mechanism. The transmission mechanism includes a fixed shaft, a first foot, and a second foot. The first foot and the second foot rotate relative to the fixed shaft. The first foot is located on the movement track of the button, and the second foot is linked with a pull rope. One end of the button is located inside the housing, and the other end is linked with one end of the transmission mechanism. The other end of the transmission mechanism is connected to the pull rope. The transmission mechanism converts the pressing force of the button into a pulling force to pull the pull rope. This kind of foot-kick switch can conveniently control the switch of the toilet and improve the use experience.

[0004] In the above-mentioned utility model patent, the toilet switch is controlled by a transmission mechanism. Since the transmission mechanism starts the telescopic movement of the pull rope by the fixed-axis rotation of the first foot and the second foot, the transmission mechanism has a large volume, the structure is not compact enough, and it is not convenient for installation and disassembly and maintenance. Summary of the Invention

[0005] Aiming at the technical problem that the volume of the toilet flushing switch is too large and not easy to maintain, this solution provides a toilet flushing switch, a toilet flushing control device, and a toilet. In this solution, the driving component provided adjusts the displacement direction of the rack group through a gear, making its structure more compact, the volume smaller, and it is more convenient for installation.

[0064] To further understand the content of the present invention, the present invention will be described in detail in combination with the accompanying drawings and embodiments. Embodiment 1

[0065] As Figure 1-2 shown, the present invention provides a toilet flushing switch, which includes a housing assembly 100 having an inner cavity 110. A driving assembly 200 is connected in the inner cavity 110, which includes a gear 210 and a rack group 220 meshing with the gear 210. The gear 210 adjusts the displacement direction of the rack group 220 to pull the pull cord 600 connected to the rack group 220 to stretch and contract.

[0066] During use, pressing the button 320 of the toilet will trigger a series of actions: Pressing the button 320 pushes one end of the rack group 220 to move along the pressing direction. Through the action of the gear 210, the movement direction of the rack group 220 can be changed to keep the rack group 220 in the same movement direction as the toilet button 320, thereby pulling the connected pull rope 600. This design of adjusting the movement direction of the rack group 220 through the gear 210 allows the lateral dimension of the drive assembly 200 to be reduced without interfering with the telescopic movement of the pull rope 600. The width of the drive assembly 200 can be set to be smaller than the opening size of the toilet button 320, making it convenient to install and remove from the opening and facilitating its maintenance and repair.

[0067] The housing assembly 100

[0068] The housing assembly 100 is fixed in an opening (not shown in the figure) provided on the toilet, and the inner cavity 110 formed therein is used to connect the drive assembly 200. The housing assembly 100 is in a long strip shape, and its maximum outer contour dimension is not greater than the opening size. The housing assembly 100 is in a long strip shape and can be directly disassembled for repair with its maximum outer contour dimension not greater than the opening size.

[0069] As Figure 3 and Figure 6 shown, specifically, the housing assembly 100 includes an upper shell 140 and a lower shell 150. The upper shell 140 and the lower shell 150 are covered to form the structure of the housing assembly 100 with the inner cavity 110. The upper shell 140 and the lower shell 150 are detachably connected by snap fasteners or screws.

[0070] As Figure 2 shown, one end of the housing assembly 100 is connected with a support body 170. The support body 170 includes two semi-circular and parallelly arranged circular plates 171, and the two circular plates 171 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 circumference of the circular plate 171. A support body 170 is connected to both the upper shell 140 and the lower shell 150, and the support body 170 connected to the upper shell 140 and the support body 170 connected to the lower shell 150 are arranged oppositely. The support body 170 can strengthen the strength of the upper shell 140 body and the lower shell 150 body, and prevent the upper shell 140 body and the lower shell 150 body from being distorted and deformed under force.

[0071] As Figure 6 shown, a first shaft column 160 is fixed in the inner cavity 110 of the housing assembly 100. One end of the first shaft column 160 is fixed on 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.

[0072] As Figure 6As shown in the figure, on both sides of the housing assembly 100 along its length direction, there are a first track 181 and a second track 182. Both the first track 181 and the second track 182 include an upper half track and a lower half track. The upper half track is fixed on the upper shell 140, and the lower half track is fixed on the lower shell 150. The upper half track and the lower half track are arranged oppositely, and there is a gap between the upper half track and the lower half track. Since the side parts of the first slider 2211 or the second slider 2221 are provided with a first tooth part 2213 and a second tooth part 2223, they need to mesh with the gear 210. Therefore, the first track 181 and the second track 182 are provided to ensure that the slider slides stably in the specified direction while not interfering with the transmission of the gear 210.

[0073] As Figure 6 As shown in the figure, limiters 190 are fixed to the tails of the driving rack 221 and the driven rack 222. The limiters 190 limit the moving distances of the driving rack 221 and the driven rack 222 within the inner cavity 110. The limiters 190 can be stoppers fixed on the housing assembly 100 or other structures that limit the moving distances of the driving rack 221 or the driven rack 222.

[0074] Drive assembly 200

[0075] As Figure 3-5 As shown in the figure, the drive assembly 200 includes a gear 210 and a rack group 220. The gear 210 is rotatably connected to the first shaft column 160, and the rack group 220 is connected to the side of the gear 210. The rack group 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 direction of the first track 181. The driving rack 221 meshes with the side of the gear 210. When the driving rack 221 slides on the first guide rail, it drives the gear 210 to rotate. The driven rack 222 is slidably connected to the second track 182 and slides along the length direction of the second track 182. The driven rack 222 meshes with the other side of the gear 210. When the gear 210 rotates, it drives the driven rack 222 to slide on the second guide rail. 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 direction of the housing assembly 100 within the inner cavity 110.

[0076] As Figure 4 As shown in the figure, the driving rack 221 includes a first slider 2211 and a driving arm 2212 fixed to one end of the first slider 2211. The other end of the driving arm 2212 passes through the housing assembly 100 and extends outside the housing assembly 100. The driving arm 2212 drives the first slider 2211 to move along the length direction of the housing assembly 100 when it is stressed. The driving arm 2212 serves as the stressed end, and one end of it extends outside the housing assembly 100, which is convenient for it to be stressed.

[0077] The first slider 2211 includes a first tooth portion 2213 on its side surface. The first tooth portion 2213 faces the gear 210 and meshes with the gear 210. First sliding grooves 2214 are respectively provided at the upper and lower ends of the first slider 2211, and the sizes of the first sliding grooves 2214 are adapted to the first guide rails. The upper and lower ends of the first slider 2211 both have the first sliding grooves 2214, which can increase the sliding stability of the first slider 2211 within the housing assembly 100. Specifically, the upper half of the first track 181 is engaged within the first sliding groove 2214 at the top of the first slider 2211, and the lower half of the first track 181 is engaged within the first sliding groove 2214 at the bottom of the first slider 2211. The upper half and the lower half of the first track 181 clamp the first slider 2211 within the gap between the upper half and the lower half, making the sliding of the first slider 2211 more stable and smooth.

[0078] As Figure 4 shown, the driving arm 2212 includes a first branch arm 2215. One end of the first branch arm 2215 is fixedly connected to the end of the first slider 2211, and the other end passes through the housing assembly 100 and extends outside the housing assembly 100. The cross-sectional shape of the first branch arm 2215 is adapted to the shape of the first connection hole provided at the end of the housing assembly 100.

[0079] The driving arm 2212 includes a strengthening member 223. The strengthening member 223 is connected to the first branch arm 2215 to strengthen the strength of the first branch arm 2215. The first branch arm 2215 is the direct force-bearing point, and it is prone to damage due to excessive or uneven force. The strengthening member 223 can enhance the strength of the first branch arm 2215 and improve the service life of the first branch arm 2215.

[0080] As Figure 4 shown, the strengthening member 223 can be a sliding rod 2231 with one end connected to the first branch arm 2215. One end of the sliding rod 2231 passes through the end of the housing assembly 100 and extends into the housing assembly 100. The sliding rod 2231 can change the force-bearing point of the first branch arm 2215, reduce its bending moment, and lower the risk of its being broken by force. The cross-sectional shape of the sliding rod 2231 is adapted to the shape of the second connection hole provided at the end of the housing assembly 100. The cross-sectional shape of the sliding rod 2231 can be circular or rectangular. Preferably, the cross-sectional shape of the sliding rod 2231 is a "cross" shape. The "cross" - shaped cross-section can simultaneously improve the transverse and longitudinal strength of the sliding rod 2231 and reduce the risk of the sliding rod 2231 being broken due to uneven force.

[0081] As Figure 5As shown in the figure, the driven rack 222 includes a second slider 2221 and a rope fixing part 2222 connected to one end of the second slider 2221.
