Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] This utility model relates to a flushing sensor device, including a water pipe 100 and a connecting component 300.

[0033] like Figure 1 and Figure 2 As shown, a solenoid valve assembly 200 is installed on the water pipe 100. The solenoid valve assembly 200 controls the opening and closing of the water pipe 100 and operates according to the sensing module 630 on the flushing sensor. The connecting assembly 300 includes a flexible connector 310, a connecting seat 320, and a fastener 330. The flexible connector 310 is a flexible pipe fitting. One end of the flexible connector 310 is inserted into the connecting seat 320, and the flexible connector 310 and the connecting seat 320 are fastened and fixed together by the fastener 330. Connecting assemblies 300 are installed at both ends of the water pipe 100, and the connecting assemblies 300 are connected to the water pipe 100 through the flexible connector 310. In actual use, the flushing sensor is applied to a urinal. Figure 7As shown, the external water inlet pipe 510 is connected with the fixing seat of one of the connection assemblies 300, and the fixing seat and the water inlet pipe 510 can be connected by threads or the like. The fixing seat connects the water inlet pipe 510 with the corresponding flexible connection 310. The water inlet pipe 510 is connected to the water supply pipeline. The external water outlet pipe 520 is connected with the fixing seat of the other connection assembly 300. The fixing seat and the water outlet pipe 520 can be connected by threads or the like. The fixing seat connects the water outlet pipe 520 with the corresponding flexible connection 310. The water outlet pipe 520 is connected to the flushing pipe of the urinal. The tap water is discharged to the urinal through the water inlet pipe 510, the connection assembly 300, the water passing pipe 100, the connection assembly 300, and the water outlet pipe 520 in sequence. During installation, the water inlet pipe 510 and the water outlet pipe 520 can be pre-buried in the wall or installed in other ways. The water inlet pipe 510 is fixed relative to the water supply pipeline, and the water outlet pipe 520 is fixed relative to the urinal. The flushing sensor device is connected with the water inlet pipe 510 and the water outlet pipe 520 through the flexible connection 310, which greatly reduces the difficulty of installation and effectively solves the problem of installation caused by environmental restrictions or size deviation.

[0034] In an embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the connection seat 320 can be provided in a cylindrical structure, and the inside of the connection seat 320 is hollow to form a plug-in cavity 321. The plug-in cavity 321 is open at both ends. A through slot 322 is formed on the side wall of the connection seat 320 and communicates with the plug-in cavity 321. The outer wall of the flexible connection 310 is provided with a clamping groove 311, which extends in a ring shape along the circumference of the outer wall of the flexible connection 310. A part of the flexible connection 310 is plugged into the plug-in cavity 321, and the clamping groove 311 is opposite to the through slot 322 after being inserted. The fastener 330 can be provided in a U-shaped structure, and the fastener 330 is provided with a clamping arm 331. The fastener 330 is sleeved on the connection seat 320, the clamping arm 331 is arranged in the through slot 322, and the clamping arm 331 is clamped on the clamping groove 311, so as to fix the connection seat 320 and the flexible connection 310 in the axial direction. Two through slots 322 can be provided on the connection seat 320, and two clamping arms 331 are correspondingly provided on the fastener 330. The two clamping arms 331 are respectively arranged in the two through slots 322 and clamped in the clamping groove 311. The two clamping arms 331 also have a certain radial clamping force on the clamping groove 311, so as to prevent the fastener 330 from being pulled out of the connection seat 320. During maintenance, the fastener 330 can be easily assembled and disassembled, so that the water inlet pipe 510 and the water outlet pipe 520 can be quickly assembled and disassembled relative to the flushing sensor device, without the need to remove the ceramic body of the urinal, and the after-sales maintenance is more convenient.

[0035] Further, as shown in Figure 3As shown, the soft connection 310 is provided with a plurality of clamping grooves 311. The clamping grooves 311 are sequentially distributed along the axial direction of the soft connection 310. A part of the clamping grooves 311 are provided with sealing rings 400. When the soft connection 310 is inserted into the connecting seat 320 or the water pipe 100, the sealing ring 400 abuts against the inner wall of the connecting seat 320 or the water pipe 100, thereby sealing the connection between the connecting seat 320 and the soft connection 310 or the connection between the water pipe 100 and the soft connection 310, so as to prevent water leakage. The part of the soft connection 310 inserted into the connecting seat 320 is provided with at least one clamping groove 311 without the sealing ring 400, which is used for clamping and fixing the buckle 330.

[0036] In an embodiment, as shown in Figure 3 The soft connection 310 includes a first pipe body 312, a second pipe body 313 and an adapter 314. The first pipe body 312 and the second pipe body 313 are formed at two ends of the adapter 314. The first pipe body 312 and the second pipe body 313 are flexible pipe bodies. One of the first pipe body 312 and the second pipe body 313 is connected with the connecting seat 320, and the other is connected with the end of the water pipe 100. The adapter 314 serves as an intermediate connecting component of the first pipe body 312 and the second pipe body 313, and the first pipe body 312 and the second pipe body 313 are communicated through the adapter 314. Meanwhile, the adapter 314 can be made of hard material, and the adapter 314 is difficult to deform. The adapter 314 is arranged according to the relative installation positions of the water pipe 100, the water inlet pipe 510 and the water outlet pipe 520. For example, the installation direction of the water pipe 100 is horizontal, and the installation direction of the water inlet pipe 510 and the water outlet pipe 520 is vertical, and the adapter 314 is arranged in L shape, so that the first pipe body 312 and the second pipe body 313 are distributed in L shape, so as to adapt to the relative installation positions of the water pipe 100, the water inlet pipe 510 and the water outlet pipe 520. Meanwhile, the soft connection 310 can be fixed to the installation environment through the adapter 314. For example, the fixing plate 315 is extended from the adapter 314, and the mounting hole 316 is formed in the fixing plate 315. The soft connection 310 is fixed in the installation environment through the mounting hole 316.

[0037] In some embodiments of the utility model, as Figure 8As shown, the flushing induction device further comprises a fixing frame 610 and a control box 620. The water pipe 100, the electromagnetic valve assembly 200 and the connecting assembly 300 are mounted on the control box 620, and the control box 620 is further provided with an induction module 630. The induction module 630 controls the work of the electromagnetic valve assembly 200 by inducting the human body. The control box 620 and the fixing frame 610 do not need to be pre-buried in the installation environment. When installing, the fixing frame 610 is installed on the plane of the ceramic body of the urinal, then the control box 620 is quickly connected to the fixing frame 610, and the control box 620 and the fixing frame 610 are fixed by mutual buckling. Most of the problems that cannot be installed due to insufficient wall space size and the cavity space of the ceramic body can be solved.

[0038] In some embodiments of the utility model, such as Figure 2 and Figure 5As shown, the electromagnetic valve assembly 200 comprises an electromagnetic valve body 210 and a water pressure self-compensating mechanism 220. The water passing pipe 100 comprises the water inlet section 110 and the water outlet section 120 in sequence. The water passing opening 130 is arranged between the water inlet section 110 and the water outlet section 120. The water inlet section 110 and the water outlet section 120 are communicated through the water passing opening 130. The water pressure self-compensating mechanism 220 is installed on the water passing pipe 100, and the water pressure self-compensating mechanism 220 comprises a springing head 230 and a first flow channel 221. The springing head 230 is elastically moved on the water pressure self-compensating mechanism 220, and the moving position has a first position and a second position relative to the water passing opening 130. Under the action of water pressure, the springing head 230 tends to be elastically moved to the first position. When the springing head 230 is at the first position, the springing head 230 blocks the water passing opening 130. When the water inlet section 110 is filled with water, the springing head 230 can be moved to the second position under the action of water pressure of the water inlet section 110, and the springing head 230 is away from the water passing opening 130 at the second position. The second flow channel 231 is arranged on the springing head 230. The water inlet section 110, the second flow channel 231, the first flow channel 221 and the water outlet section 120 are communicated in sequence. The electromagnetic valve body 210 is installed on the water pressure self-compensating mechanism 220, and the opening and closing of the first flow channel 221 are controlled through the electromagnetic valve body 210. Under normal circumstances, the electromagnetic valve body 210 closes the first flow channel 221, and at this time, the water in the water inlet section 110 enters the first flow channel 221 through the second flow channel 231, and the springing head 230 is kept at the first position by cooperating with the water pressure on the side of the first flow channel 221, thereby blocking the water passing opening 130. When flushing is needed, the electromagnetic valve body 210 is opened, the first flow channel 221 is opened, the water in the first flow channel 221 is discharged to the water outlet section 120 to release pressure, and the springing head 230 is moved to the second position under the action of water pressure of the water inlet section 110. The water passing opening 130 is opened, and the water in the water inlet section 110 flows to the water outlet section 120 through the water passing opening 130, and then is discharged through the connecting assembly 300 and the water outlet pipe 520 to flush. After a period of flushing, the electromagnetic valve body 210 closes the first flow channel 221. The first flow channel 221 is gradually recharged and pressurized through the second flow channel 231. When the water pressure of the water inlet section 110 is large, the first flow channel 221 is quickly recharged, and the springing head 230 is quickly moved to the first position. When the water pressure of the water inlet section 110 is small, the first flow channel 221 is relatively slowly recharged, and the time for moving to the first position is long, thereby increasing the flushing time.

[0039] Further, as Figure 5 and Figure 6As shown, the elastic head 230 comprises a shaft body 240. The second flow channel 231 is formed in the shaft body 240 along the axial direction of the shaft body 240. The shaft body 240 is provided with a water passing hole 241 along the radial direction. The second flow channel 231 is communicated with the water inlet section 110 through the water passing hole 241. The shaft body 240 is sleeved with an elastic ring 250. The elastic ring 250 is aligned with the water passing hole 241, and the elastic ring 250 shields the water passing hole 241. The elastic ring 250 will be elastically deformed according to the water pressure in the water inlet section 110, and the size of the elastic deformation will change the shielding area of the water passing hole 241. When the water pressure in the water inlet section 110 is large, the deformation amount of the elastic ring 250 is large, and the shielding area of the water passing hole 241 is reduced, so that water can quickly pass through the water passing hole 241, the first flow channel 221, and supplement to the second flow channel 231, thereby accelerating the moving speed of the elastic head 230 to the first position. When the water pressure in the water inlet section 110 is relatively small, the deformation amount of the elastic ring 250 is small, and the shielding area of the water passing hole 241 by the elastic ring 250 is small, thereby slowing down the supplement speed of water passing through the water passing hole 241, the first flow channel 221, and the second flow channel 231, and thereby slowing down the moving speed of the elastic head 230 to the first position, and lengthening the drainage time of the water inlet section 110 through the water outlet 130 to the water outlet section 120.

[0040] Based on the above embodiment, the shaft body 240 comprises a first shaft section 242 and a second shaft section 243 coaxially arranged. The outer diameter of the first shaft section 242 is smaller than the outer diameter of the second shaft section 243. The water passing hole 241 is formed on the first shaft section 242, and the elastic ring 250 is sleeved on the first shaft section 242 and abuts against the second shaft section 243. The water in the water inlet section 110 acts on the elastic ring 250 to extrude the elastic ring 250 in the direction of the second shaft section 243, and the end of the second shaft section 243 supports the elastic ring 250, so that the elastic ring 250 is deformed under different water pressures.

[0041] Further, the water pressure self-compensating mechanism 220 further comprises a base body 260, which can be provided as a box-shaped structure. An elastic diaphragm 270 and an elastic member 280 are arranged between the elastic pressing head 230 and the base body 260. The elastic member 280 can be a spring. The elastic member 280 exerts an elastic force on the elastic pressing head 230, which tends to move to the first position. The elastic diaphragm 270 and the base body 260 define a water passing cavity 261. The elastic member 280 can be located in the water passing cavity 261, and one end of the elastic member 280 abuts against the base body 260, and the other end abuts against the elastic pressing head 230. The first flow channel 221 is arranged on the base body 260. The first flow channel 221 is in communication with the second flow channel 231 through the water passing cavity 261. Water is stored in the water passing cavity 261 through the second flow channel 231, so as to increase the water storage on the side of the first flow channel 221 of the elastic pressing head 230. When the elastic pressing head 230 moves, the elastic diaphragm 270 deforms along with the elastic pressing head 230. When the elastic pressing head 230 moves from the second position to the first position, the elastic diaphragm 270 deforms, and the volume of the water passing cavity 261 increases.
