Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view, part of which is shown as a cross-section, to show a schematic internal structure of a bubble whisk 1 according to the present invention. In the figure, a foaming device 1 is a detergent for filling a casing 2 with a detergent liquid, that is, a soap liquid and high-pressure carbon dioxide gas, and for ejecting soap bubbles from a nozzle 3 serving as the bubble ejection port. A liquid cylinder, that is, a soap liquid cylinder 4 is stored. The soap liquid cylinder 4 has a well-known gas cylinder structure in which soap bubbles are ejected from the bubble outlet 4a by pressing the head of the soap liquid cylinder 4, and is sandwiched between the mounting table 5 and the pressing portion 6 for use. With this, when the soap liquid inside becomes empty, it can be replaced with a new soap liquid cylinder.

The pressing portion 6 that presses the head of the soap liquid cylinder 4 has a tubular insertion portion 6 a formed therein, and one end of the insertion portion 6 a connects the foam outlet 4 a of the soap liquid cylinder 4 to the foam outlet 4 a. The cover and the other end are connected to the nozzle 3 via a flexible hose 6b. Further, the pressing rod 6 has a projecting rod 7 connected to the upper surface thereof. The projecting rod 7 penetrates the partition wall 8 and projects to a position where it comes into contact with a rotating cam 9 described later, and its head is formed in a smooth hemispherical shape. Reference numeral 7a is a panel provided around the projecting rod 7 and is engaged with the flange-shaped locking member 7b and the partition wall 8 to urge the projecting rod 7 and the pressing portion 6 connected thereto upward. is doing.

Reference numeral 10 denotes a coin insertion slot, and coins inserted from the coin insertion slot 10 are stored in the coin storage unit 11. A switch mechanism 12 as the coin detecting unit for detecting the inserted coin is provided inside the coin storing unit 11. The inserted coin falls on the upper surface of the switch mechanism 12. By doing so, the switch is turned on to detect the insertion of a coin, and this detection signal is sent to the counter section described later. Reference numeral 13 is a substrate on which a control element such as the counter portion is mounted and attached to the inner surface of the housing 2, and 14 is a limit switch for detecting the rotation of the cam 9. Further, a cylinder empty display lamp 15 as the soap liquid cylinder empty display section for indicating that the soap solution cylinder 4 has been emptied by use is disposed on the front surface of the housing 2 and, as will be described later, It lights up when a predetermined number of coin insertions are detected, and indicates that the soap liquid cylinder 4 is empty.

FIG. 2 is an external perspective view showing only the cam 9, the motor 16 for rotating the cam 9, and the gear portion 17 in an extracted manner. In the figure, the cam 9 has a radial notch 9a, which is a semicircular notch from the peripheral edge of the cam 9 toward the center in the radial direction, and a thickness of the peripheral edge of the cam 9 that is about half the thickness in the thickness direction. Thus, a thickness direction notch 9b is formed by cutting out toward the center in a crescent shape. Then, as shown in FIG. 1, the projecting rod 7 is positioned at a notched semicircular 9a ′ portion of the radial cutout 9a, and the projecting rod 7 is cammed by the rotation of the cam 9. The thickness of the peripheral edge of 9 is pressed, and the pressure of the projecting rod 7 causes the bubbles of soap solution to be ejected from the soap solution cylinder 4. Further, a limit switch 14 is disposed in the thickness direction cutout portion 9b, the arm 14a of the limit switch 14 extends to the cutout thickness 9b 'portion, and the minute rotation of the cam 9 causes the thickness 9b' portion to move to the arm portion. 14a is stopped, and the limit switch 14 is turned on by stopping the arm 14a. The cam 9 is rotated by the rotation of the motor 16 via the gear portion 17, and the rotation speed of the cam 9 is set so as to rotate at a predetermined speed by the intervention of the gear portion 17.

FIG. 3 is a diagram showing a control configuration of the bubble extractor 1. In the figure, a contact 12 'is a contact of the switch mechanism 12 for detecting the coin insertion shown in FIG. 1, and when the coin is inserted, the contact 12' is turned on. Further, the contact 14 'is also the contact of the limit switch 14 shown in FIG. 1, and as described above, the minute rotation of the cam 9 causes the notched thickness 9b' of the cam 9 to stop the arm 14a. As a result, this contact 14 'is turned on. An RC integrating circuit is formed between the contact 12 'and the contact 14' by a resistor R and a capacitor C, and the output of this circuit is input to the base of an NPN transistor T. The motor 16 shown in FIG. 1 is connected to the collector of the transistor T, and a voltage of 3 V is applied to the motor 16. D is a diode for preventing surge current.

Reference numeral 19 denotes a counter section, which inputs a pulse generated each time the contact 12 ′ of the switch mechanism 12 is turned on, through a noise prevention gate circuit 18, and counts the number of input pulses. I do. The counter unit 19 is composed of an 8-bit counter, which counts up each time a coin is inserted, and when 32 pulses, that is, 32 coins are inserted, the empty cylinder display as the end signal is displayed. The lighting of the lamp 15 is controlled.

In the bubble dispenser 1 configured as described above, first, when a coin (not shown) is inserted from the coin insertion slot 10 shown in FIG. 1, the inserted coin drops on the switch mechanism 12. This drop of the coin turns on the contact 12 'shown in FIG. 3, and this ON operation causes the RC integrator circuit to output a pulse to the base of the transistor T. The transistor T receives the output of this pulse and becomes conductive, and the conduction of the transistor T causes the motor 16 to operate. This operation is an instantaneous operation of only the pulse, but the cam 9 makes a minute rotation by this instantaneous operation of the motor 16, and the minute rotation of the cam 9 causes the arm 14a of the limit switch 14 shown in FIG. The cam 9 is pressed against the notch thickness 9b '. The contact 14 'of the limit switch 14 is turned on by the pressing of the arm 14a. Electric power is continuously supplied to the motor 16 by the ON of the contact 14 ', so that the motor 16 continuously rotates.

The rotation of the motor 16 is reduced by the gear portion 17, and the cam 9 connected to the gear portion 17 rotates at a predetermined speed. The thick peripheral portion of the rotating cam 9 presses the head of the projecting rod 7, and by this pressing, the projecting rod 7 and the pressing portion 6 connected thereto are pushed downward and moved by this movement. Bubbles of the soap liquid cylinder 4 Bubbles of the soap liquid are ejected from the nozzle 3 from the outlet 4a via the hose 6b. During this time, since the arm 14a of the limit switch 14 is in contact with the peripheral thickness portion of the cam 9, the contact 14 'remains in the ON state, the motor 16 continues to rotate, and the soap bubbles continue to be ejected from the nozzle 3. In this embodiment, the bubble is jetted for 5 seconds.

When the cam 9 makes one rotation and returns to the position shown in FIG. 1, the projecting rod 7 and the pressing portion 6 connected thereto rises by the urging force of the spring 7 a, which causes the soap liquid cylinder 4 to move. Since the pressed state of the head is released, the ejection of bubbles of soap solution also stops. At the same time, when the cam 9 rotates to this position, the arm 14a of the limit switch 14 comes out of contact with the thickness portion of the peripheral edge of the cam 9 so that the contact 14 'becomes OF F and the rotation of the motor 16 is stopped. To do.

The contact 12 'shown in FIG. 3 is the contact of the switch mechanism 12 for detecting the insertion of a coin as described above, and this ON signal is generated every time the contact 12' is turned on when a coin is inserted. Is sent to the counter section 19 through the noise prevention gate circuit 18 and the number of coin injections is counted. As described above, the counter unit 19 is composed of an 8-bit counter and controls the lighting of the cylinder empty display lamp 15 by inserting coins 32 times, that is, by inputting 32 pulses. 15 is lit to indicate that the soap liquid cylinder 4 is empty.

The empty soap liquid cylinder 4 is replaced. By replacing the soap liquid cylinder 4, the cylinder empty display lamp 15 is turned off and the count number of the counter section 19 is reset to return to the initial state.
