Detailed Implementation

[0042] Example 1

[0043] The following is combined with Figures 1-14 This utility model will be described in detail.

[0044] A toilet cleaning device includes a main body and a guide vane 30. The main body has a water inlet channel 101, and the guide vane 30 is connected to the main body. The gap between the guide vane 30 and the main body forms a spray channel 40, which faces the urinal wall adjacent to the main body. The water inlet channel 101 communicates with the spray channel 40, thereby reducing blind spots in cleaning the urinal wall. Simultaneously, the main body has a mounting position 2011 with an opening at one end. The mounting position 2011 is used to fix the position between the main body and the urinal, and there is an adjustable gap between the mounting position 2011 and the urinal to accommodate different types of urinals. Specifically, as shown... Figure 1 and Figure 2 As shown, the base body 20 has wing plates 201 on both sides, and mounting positions 2011 on the wing plates 201. The mounting position 2011 is an elongated hole with an opening at one end. The elongated hole forms an adjustment gap, so that the body can be adjusted along the elongated hole, thereby adapting to different types of urinals or offsetting errors caused by manufacturing precision.

[0045] like Figure 11 and Figure 14 As shown, the water-passing area of ​​the jet channel 40 gradually increases along the water outlet direction, thereby expanding the flushing area of ​​the urinal 701 and improving the cleaning effect. Specifically, the expansion angle β of the water outlet end of the jet channel 40 is 124°, but it is not limited to this. Figure 6 The water outlet of the jet channel 40 is shown to have a guide surface 303, which guides the water flow towards the wall of the urinal near the main body. Specifically, the guide surface 303 is located on the guide vane 30, and the angle α between the guide surface 303 and the bowl 701 of the urinal is 24°, but it is not limited to this. Figure 11 and Figure 13 As shown, a water-blocking protrusion 301 is provided in the center of the spray channel 40, making the water passage area in the middle of the spray channel 40 smaller than the water passage area on both sides of the spray channel 40. Furthermore, the water-blocking protrusion 301 is located on the side of the guide plate 30 facing the nozzle body 10. When the water pressure is low, the water flow on both sides of the spray channel 40 is increased to prevent water from flowing directly out from the middle, thus expanding the cleaning range. In addition, the water flow velocity in the middle of the spray channel 40 is increased to improve the flushing force on the wall surface and ensure that the wall surface is basically clean.

[0046] like Figure 4As shown, the main body includes a base body 20 and a nozzle body 10 connected to the base body 20. Mounting positions 2011 are provided on both outer sides of the base body 20. The nozzle body 10 has a water inlet channel 101, and a guide vane 30 is connected to the nozzle body 10. The base body 20 has a first buckle 202, and the nozzle body 10 has a first slot 102. The nozzle body 10 is connected to the base body 20 through a snap-fit ​​connection between the first buckle 202 and the first slot 102. An adjustment space 50 exists between the first buckle 202 and the first slot 102 to accommodate urinals with different porcelain thicknesses, such as... Figure 9 As shown. The base body 20 is provided with ribs 203. When the nozzle body 10 is connected to the base body 20, the ribs 203 abut against the nozzle body 10 to limit the relative displacement between the base body 20 and the nozzle body 10. In other embodiments, the base body 20 may be provided with a first slot 102, and the nozzle body 10 may be provided with a first buckle 202 and ribs 203.

[0047] Figure 11 The guide vane 30 is shown to have several first positioning parts. Figure 10 The nozzle body 10 is shown to have a second positioning part. When the guide vane 30 is connected to the nozzle body 10, the first positioning part and the second positioning part are paired and connected one-to-one to improve the installation efficiency of both. Specifically, the first positioning part is a positioning groove 302, and the second positioning part is a positioning protrusion 103.

[0048] like Figure 4 As shown, the cleaning device also includes a control device and a sensing device electrically connected to the control device. The sensing device is detachably connected to the nozzle body 10. The control device controls whether water flows out of the spray channel 40 based on whether the sensing device detects that someone is using the urinal. The control device includes, but is not limited to, PLA, PLC, and microcontroller. The sensing device includes a sensing window 601 and a sensor 603 connected to the sensing window 601. The sensing window 601 is detachably connected to the nozzle body 10 for easy disassembly for maintenance or replacement. The nozzle body 10 is provided with a clearance hole 104 to allow space for the sensor 603. The sensor 603 is connected to the controller, which is connected to a control valve that opens and closes the water inlet channel 101. When the sensor 603 is activated, the controller operates the control valve to open the water inlet channel 101 based on the activation information of the sensor 603, so that water flows out of the spray channel 40 to flush and clean the urinal.

[0049] The sensor window 601 is provided with a plurality of second latches, including second latch A6021, second latch B6022 and second latch C6023. The nozzle body 10 is provided with second slots A1051, second slot B1052 and second slot C1053 corresponding to the second latches A6021, second latch B6022 and second latch C6023, respectively as follows:Figures 5 to 7 As shown.

[0050] Figure 9 The sensor window 601 is shown to have a receiving groove 6011, and the sensor 603 is encapsulated in the receiving groove 6011 with potting compound to improve the waterproof performance of the sensor 603.
