However, the infrared sensor is usually disposed in an additional space of the urinal, and the wiring layout and other factors need to be considered, and in addition, the sensing flushing device has a high flushing noise and no economical and effective anti-siphon function, which brings a bad use experience to users.

From this, this disclosure aims at providing a response bath device with prevent siphon function, through integrated response module and prevent siphon module, when realizing that the accuracy is washed by water in order using water wisely, provides low noise and washes water and prevent that sewage from flowing back to effect such as pipeline. Herein, the sensing module is described in the form of infrared sensing, but does not exclude conductive sensing, capacitive sensing, etc. suitable for combination, so that the sensing urinal of the present disclosure is suitable for various occasions based on different needs.

Fig. 1 illustrates an embodiment of an inductive urinal 100, for example made of ceramic, and including a urinal body 110, although the structure/size/shape is not intended to be limiting. Referring to fig. 3, the inductive urinal with an automatic flushing function is formed with an inner chamber 111 for receiving liquid, an opening is formed on an inner wall of the inner chamber 111 for mounting a flushing nozzle 130, and an opening is formed at a bottom end to provide a receiving cavity for receiving a control assembly. In the illustrated embodiment, the receiving cavity 112 extends from the bottom to the top of the urinal body 110 to accommodate an induction flushing device, and in some cases a bottom cover plate may be provided to open or close the receiving cavity 112. Herein, the back of the urinal means the side of the urinal for mounting to a wall, the front means the side facing the user, and the inner wall means the side facing the inside of the chamber when describing the inner chamber 111 and the receiving cavity 112.

Referring to fig. 2 to 4, the induction flushing device is installed in the accommodating cavity 112 and includes a water inlet and outlet assembly, a water discharge assembly 150, a solenoid valve assembly 160 and a power supply assembly 170. The electromagnetic valve assembly 160 controls the on/off of the water path, and includes an electromagnetic valve, and a water inlet connector and a water outlet connector connected to the electromagnetic valve. The power supply assembly 170 is an external ac power supply or a dc battery box, and is connected to the solenoid valve assembly 160 through a wire to provide power. The water inlet and outlet assembly includes a water inlet pipe (not shown) and a water outlet pipe 133, and the water outlet pipe 133 has a water inlet 132 connected to the water inlet pipe and a water outlet connected to the flush head 130. In the illustrated embodiment, the flush head 130 is advantageously positioned above the inlet pipe, i.e., above the urinal 100. In this way, the flushing port 131 of the flushing nozzle can be arranged towards the lower inner chamber 111 to achieve a complete flushing of the inner wall of the inner chamber 111.

The drain assembly 150 includes a water inlet port 151, a drain port 152, and a trap 153 connected therebetween, wherein the water inlet port 151 is hermetically connected to the outside of the drain pipe port of the urinal and is generally provided with a sealing film, and the trap 153 is used for storing water to perform a deodorizing function. The drain port 152 of the drain assembly 150 extends through a mounting plate 154 to communicate with an external drain, the mounting plate 154 being secured to the wall, such as by fasteners such as screws.

In some embodiments, as shown in fig. 1 and 2, the sensing module is an infrared sensing assembly, and includes an infrared sensing controller 180 connected to the solenoid valve assembly 160, and an infrared sensing head lead 143 connected to the infrared sensing controller 180, the infrared sensing head lead 143 being attached to the water inlet and outlet assembly. Specifically, the ir sensor head wire 143 has a power supply end 142 connected to the wire, and a sensing end 141 attached to the flush head 130, wherein the flush head 130 is provided with a notch for exposing the sensing end 141 to provide a sensing window in the ir sensing mode.

In this embodiment, since the sensing end of the infrared sensor head wire is integrated at the flush head and does not interfere with the outlet pipe 133 during installation and use, the space at the flush head and in the receiving cavity of the urinal is advantageously utilized without affecting the flush performance, and no additional installation space for the infrared sensor head is required. In addition, the position of the infrared induction head is corresponding to the conventional use position of a user, so that the induction detection is more accurate, and the mistaken flushing is prevented. After the sensing signal is sent to the infrared induction controller, the infrared induction controller sends a signal to the electromagnetic valve assembly connected with the infrared induction controller, and then the electromagnetic valve assembly controls the opening or closing of flushing, so that the urinal in the existing infrared induction mode is improved at the most economic cost.

The induction flushing device of the present disclosure is further provided with an anti-siphon module 190, wherein the anti-siphon module 190 is associated with the water inlet and outlet assembly and is arranged above the water inlet and outlet assembly. More specifically, the anti-siphon module 190 is disposed at an upper portion of the receiving cavity 112 above the head 130, and the outlet pipe 133 is connected to the head 130 via the anti-siphon module 190. Advantageously, the anti-siphon module 190 is configured to communicate the path of the water inlet and outlet assembly when the flush is turned on and to block the path of the water inlet and outlet assembly when the flush is turned off.

In connection with the embodiment shown in fig. 5 and 6, the anti-siphon module 190 is configured as a receiving chamber including an inlet end 191 connected to the outlet pipe 133 and an outlet end 192 connected to the flush head 130, and an anti-siphon pad 193 is disposed in the receiving chamber. In this manner, when the flush is open, inlet port 191 and outlet port 192 communicate, and when the flush is closed, inlet port 191 and outlet port 192 are blocked by siphon-proof gasket 193. In other words, the anti-siphon pad 193 can move between the first position at the top of the receiving chamber and the second position at the bottom of the receiving chamber under the control of the inlet water pressure of the outlet pipe 133 or its own weight. Wherein in the first position, the anti-siphon pad 193 exposes the outlet end 192 to communicate with the inlet end 191 and the outlet end 192 to communicate the path of the water inlet and outlet assembly; in the second position, the anti-siphon pad 193 closes the outlet end 192 and blocks the inlet end 191 and the outlet end 192, thereby blocking the path of the water to and from the water assembly.

As described above, the anti-siphon module 190 is disposed above the flush head 130, and in order to effectively obtain the anti-siphon function, the anti-siphon module is disposed at a position at least 25mm, i.e., about 1 inch, from the upper end of the water inlet and outlet assembly. As shown in fig. 6, the distance D is specifically the distance between the outlet end 192 of the anti-siphon module and the flush head 130. Also, a draft tube 194 is provided between the outlet end 192 and the flush head 130 in order to introduce water flow from the outlet end 192 to the flush head 130.

Advantageously, the anti-siphon module 190 is a vacuum breaker valve. In some embodiments, the anti-siphon module further comprises a valve cover 195 adjacent the outlet end 192, the valve cover 195 being provided with an air inlet 196, the air inlet 196 communicating with the outlet end 192 when flushing is closed.

The operation of the induction flushing device with an anti-siphon function of the present disclosure will be described with reference to fig. 5 and 6.

Referring first to fig. 5, when the sensing module senses that a human body or an object is approaching for a period of time and moving away from the sensing module, a signal is sent to the solenoid valve assembly connected with the sensing module, the solenoid valve assembly controls to open the flush, when the water outlet pipe 133 is filled with water, the anti-siphon pad 193 moves upward to the first position under the pressure of the water flow flowing out from bottom to top in the water outlet pipe 133, at this time, the inlet end 191 and the outlet end 192 of the anti-siphon module are communicated, and the anti-siphon pad 193 seals the air inlet 196. In this manner, the water flow is directed in the direction of the arrow through the path of the outlet tube 133, outlet end 192, drain tube 194 and flush head 130 to flush the inner wall of the urinal cavity. Because the setting of drainage tube 194, there is baffling passageway in rivers from exit end 192 to the route of bath shower nozzle 130, this also makes and to reduce water pressure and velocity of flow relatively when washing by water, and then reduces the noise of washing by water, promotes user's use and experiences.

The flush time may be achieved by setting the solenoid valve assembly, for example, 3 to 5 seconds. After the flush has been performed for a predetermined time, the solenoid valve assembly controls the flush to be turned off, and the water flow in the outlet pipe 133 stops from bottom to top, so that a certain degree of negative pressure is formed below the anti-siphon pad 193, and at the same time, the anti-siphon pad 193 moves downward to the second position under the gravity of the anti-siphon pad 193 itself. At this time, as shown in fig. 6, the outlet end 192 of the anti-siphon module is communicated with the air inlet 196 and is blocked from the inlet end 191, and the external air enters the upper part of the accommodating cavity through the air inlet 196 as shown by an arrow, so that the external air pressure inside the accommodating cavity is kept consistent, the negative pressure is eliminated, the path of the water inlet and outlet assembly is blocked, and the sewage backflow at the flushing nozzle 130 is prevented. Similarly, the outlet end 192 is higher than the position of the flushing nozzle 130 and the drainage tube 194, so that the situation that water possibly existing in the accommodating cavity flows back to the water outlet pipe is further avoided, and the anti-siphon performance is stable and reliable.

The response bath device of this disclosure is through integrated response module and anti-siphon module to arrange the anti-siphon module in business turn over water assembly's top, open or close the in-process of washing by water according to the inductive signal control, anti-siphon module realizes the intercommunication and the blocking of business turn over water assembly's route. When the exit end of anti-siphon module communicates with outside atmosphere via the air inlet, to the negative pressure that produces in the outlet pipe, can directly inhale outside air and offset the negative pressure, effectively play anti-siphon effect, avoid bath shower nozzle department sewage backward flow to pollute pipeline water. This response bath device overall structure is exquisite, and the stable performance just reduces the bath noise. In addition to the urinal application illustrated herein, the present invention may be adapted for use in a variety of other suitable applications.
