Abstract

(57) [Abstract] [Purpose] To provide a structure that prevents excess detergent solution from dripping after supplying detergent solution in an automatic detergent solution supply device that automatically supplies detergent solution by infrared sensing. The purpose is to make it possible to save on usage. [Configuration] Pour the detergent solution into the upper case 11 of the case 10, and
A motor 32 mounted in the press 12 is actuated by infrared sensing to rotate a pressing body 34 having a plurality of pressing rollers 344. A pressure roller 344 presses a transport pipe 33 whose both ends are connected to the detergent liquid outlet 112 of the upper case 11 and the detergent liquid outlet 122 at the bottom of the lower case 12. As the pressing body 34 rotates, each pressing roller 344 sequentially pushes the detergent liquid in the transport pipe 33 to the flow port 122 and causes it to flow out. When the motor 32 is stopped, at least one pressure roller 344 stops while pressing the transport pipe 33, so that the outflow of the detergent liquid is immediately blocked.

[Conventional technology]

Public toilets located in general department stores, hotels, or transportation stations The hand-washing detergent dispenser installed in the From the one where the detergent liquid flows out when you press the push button by hand, to the current infrared ray The sensor rotates the motor to drive an eccentric wheel and press the detergent bottle open/close switch. It has even evolved into an ``automatic detergent dispenser'' that drains the detergent solution. This kind of subordination The new ``detergent liquid automatic supply device'' uses infrared sensing to fully automatically control the flow of detergent liquid. It can be trolled, making it even more convenient for users. But long This type of automatic feeder uses the principle of infrared sensing control to rotate the motor. Theoretically, the timing of the rotation of the motor and the outflow or blockage of the detergent solution are The timing of the shutoff should coincide, but in reality, the timing of the detergent solution stopping should match. The timing may be slightly delayed. This means, for example, that the motor rotates during use. After driving the eccentric wheel and pressing the switch to let the detergent liquid flow out, turn the motor off. This is because the eccentric still slightly presses the switch when stopped, which causes the detergent to The outflow of liquid does not stop immediately, and some of it drips and is washed away, resulting in waste and being useless. You may feel stool.

[Means to solve the problem] In order to achieve the above purpose, this invention uses a motor that rotates by sensing infrared rays. Distributed at substantially equal intervals near the periphery of the rotary disk that is rotated by a motor. As the multiple pressure rollers move in the rotational direction as the rotary disk rotates, The detergent liquid transport pipe is pressed, and the detergent liquid in the transport pipe is directed to the flow port located in front of the rotation direction. The structure is such that the liquid is extruded in the opposite direction and flows out from the flow port.

[0005] In a preferred embodiment, a storage chamber is formed inside to accommodate the detergent solution. At the same time, the upper case has an outlet at the bottom and the inner case is screwed onto the upper case. In addition to forming a storage chamber in the lower part, the lower part has a flow opening at the bottom, and the upper part of the upper part is covered. A case body formed from a lid; an electric circuit board attached to the bottom inside the lower case, and a flow port. An electronic circuit means formed by conducting with an infrared sensor installed nearby; and a lower case. The motor is connected to the base fixed inside the base and connected to the electric circuit board, and the motor is connected to the base fixed inside the base. Both ends are connected to the outlet of the upper cabinet and the outlet of the lower cabinet, respectively, so as to touch the peripheral wall surface. A transport pipe consisting of an elastic hose that transports the detergent liquid is extended, and a pressure-welded rod is attached to the rotary disk. Each of the pressing rollers is intermittently transported by the rotational movement of the pressing body formed with rollers. Pressing the pipe in one direction from the inner circumference causes the pipe wall of the transport pipe to pulsate repeatedly, allowing the detergent solution to flow into the flow port. The detergent solution in the transport pipe is made to flow out from the flow port by means of transport for transporting the detergent to the pipe. . Further, the pressing body has a fitting hole in the center and is fitted onto the rotating shaft of the motor. The pressure contact rollers are distributed at equal intervals near the periphery of the upper surface of the rotary disk. There are five shaft pins each rotatably fitted with a pressure contact roller, and It may also be structured to cover with a covered rotary disk.

With this device configured as described above, when you reach out your hand below the flow opening, you will see a red As the motor rotates from sensing the external wire, the multiple pressure rollers also rotate. Several pressure rollers press the transport pipe and direct the detergent liquid in the transport pipe to the flow port. Let it flow out. On the other hand, when the motor stops rotating, the pressure roller also stops; One or more pressure rollers then press against the transport tube. This allows the washing The outflow of the chemical solution is immediately stopped and further dripping does not occur. The above and other objects, features and advantages of this invention will be explained below with reference to the drawings.

The pressing body 34 is the axis When the body is fitted onto the rotating shaft of the motor 32, several pressure rollers 344 are The force contacts the transport pipe 33, and as the pushing body 34 rotates by the motor 32, the transport pipe 33 is sequentially pushed. Pressure is applied to send the detergent solution toward the flow port 122 and from there.

0010 FIG. 4 shows a state in which the pressing body 34 presses the transport pipe 33 and causes the detergent liquid to flow out. As shown in the figure, the pressing body 34 is rotated by the drive of the motor 32, and the pressing body 34 is rotated by the driving of the motor 32. When the roller 344 reaches the position between A and C, it pushes the transport pipe 33 against the inner peripheral wall of the base 31 with an appropriate force. It will put pressure on you. When the motor 32 continues to operate, each The pressure roller 344 sequentially presses the transport pipe between A and C and sends the detergent liquid in the rotational direction C. It flows out from the point A to C, that is, in the direction of the flow port 122. And once motor 32 When stops rotating, there is at least one pressure contact between A and C, as can be seen from the diagram.

Then, the motor 32 starts operating. When stopped, each pressing roller 344 also stops together with the pressing body 34, and at this time, 1 or 1 Since the pressure rollers 344 press against the transport pipe 344, the detergent solution can be immediately prevented from flowing out. will be stopped. That is, when the rotation of the motor 32 stops, the detergent solution stops flowing out at the same time. No additional detergent drips.

0012 Also, the pressure roller 344 of the pressing body 34 is rotatably fitted onto the shaft pin 343. When the pressing body 34 is rotated by the drive of the motor 32, a pressure roller is pressed against the transport pipe 33. Each of the pipes 344 reduces friction with the transport pipe 33 by rotating itself. Ru. Therefore, the friction between the pressure roller 344 and the transport pipe 33 causes the pressure body 34 to rotate. It is not difficult to do so.
