Abstract

PURPOSE:To select a jet stream corresponding to the region and state of the body and to prevent the shock caused by the sudden change of the jet stream by making it possible to select three kinds of jet stream emitting controls of 'weak', 'strong' and 'intermittent' by main body push button switches and setting the operation order of the jet stream to 'weak' 'strong' 'intermittent'. CONSTITUTION:When a push button 29 is pushed, a display lamp 32 of 'weak' lights and a jet stream of 'weak' is emitted from a jet stream orifice 21. When the push button 29 is further pushed, a display lamp 33 of 'strong' lights to emit a jet stream of 'strong'. When the push button 29 is furthermore pushed, a display lamp 34 of 'intermittent' lights to emit a jet stream repeating 'strong' and 'weak'. When the push button 29 is further pushed, operation is stopped. By this method, the jet stream corresponding to the region and state of the body can be used and, at the same time, the shock caused by the sudden change of the jet stream is relieved in bodily sensation. Since the jet stream is not interrupted by intermittent operation, the start current of a motor 14 is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bubble massager used in a bathtub, which has a structure in which three types of bubble jets can be discharged and selected, and an operation mode can be displayed. .

[Conventional technology]

As described in Utility Model Application Publication No. 59-3875, conventional bubble massagers have only one type of bubble jet, and it is not possible to select and use the jet according to the body part and condition. Ta.

[Problem to be solved by the invention]

The above conventional technology does not consider the type and selection of the bubble jet, that is, the jet (jet force) depending on the body part and condition (stiffness, muscle pain, etc.), and only a certain jet is used. There was a problem in that it was not possible to select the jet stream according to the body part and condition.

The present invention controls the ejection of a jet according to the body part and condition,
To provide a bubble massager which allows a user to select and display the operation mode of the jet being used.

[Means to solve the problem]

In order to achieve the above purpose, three types of weak, strong, and intermittent (pulsating)
Different types of jets can be controlled and selected using a single push button switch on the main body. Furthermore, in order to soften the shock caused by sudden changes in the body sensation caused by jet flow switching, a control system was adopted in which the jet types are ejected in the order of weak → strong → intermittent. In addition, the intermittent jet flow is repeated between strong and weak jets to prevent the jet from stopping, which alleviates the stress when starting the motor and reduces the starting current. Furthermore, in order to display the operating mode of the jet, the device has a structure that includes a case that does not come into contact with the indicator lamp (LED) on the main body substrate and that houses the main body substrate and a light guide that can be sealed with water.

[Effect]

It controls the discharge of three types of jets: weak, strong, and intermittent, and can be selected sequentially in the order of weak → strong → intermittent (strong ← weak repeat) with a single push button switch on the main body. This makes it possible to use a jet stream that is appropriate for the part and condition of the body, and at the same time, by starting from a low level, it is possible to soften the shock caused by sudden changes. In addition, the intermittent operation is repeated from strong to weak, so that the jet flow is not interrupted. In other words, by not stopping the motor, the stress at the time of starting the motor is alleviated, and the starting current is reduced.

Furthermore, in order to display the operating mode of the jet flow, the structure is such that it has a case that does not make contact with the indicator lamp (LED) on the main body board, houses the main body board, and a light guide that can be sealed with water.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 1 shows the main body structure that is the basis of the present invention. Main case 4 consisting of front case 1, rear case 2 and base 3
The battery 7 is stored in the lower chamber of an inner case 6, which is water-sealed into two upper and lower chambers with lead wire packing 5, and the battery 7 is sealed with rubber packing 8 and battery cover 9. The control circuit 10 is arranged in the room, and the battery 7
A circuit cover 12 equipped with a terminal 11 for charging the battery and a rubber packing 13 are used to seal the battery. Furthermore, a motor case 15 equipped with a pump motor 14 is attached, and the inner case 12 is sealed from the outside with a packing 16.

At the bottom of the motor case 15, there is a water seal formed by an oil seal 17, and an impeller 18 rotated by a pump motor.
is provided, and together with a pump power bar 20 equipped with a suction joint 19, forms a spiral pump section, and the bubble jet port 21 of the pump section is connected to a nozzle 22, a diffuser 23, and an intake port 24.
An intake pipe 25, an intake switching valve 26, and an intake ball 27 are installed in the intake port 24 to guide air from the outside. Further, the circuit force bar 12 is provided with a push button 29 containing a magnet 28, and operation (jet flow switching) and stop are performed by turning on and off a reed switch 30 provided in the control circuit 10. This device is used inside a bathtub, and the intake ball 27 and intake pipe 31 for sucking air are placed outside the bathtub, and the pump operates to suck in water and air from each part, and the diffuser section 23 pumps out the water. and air are mixed and a bubble jet is discharged from the bubble jet port 21, and the bubble jet provides a massage effect.

The main body control circuit 10 shown in FIG. 5 controls the discharge of three types of jets: weak, strong, and intermittent.
Sequential selection is possible in the order of strong → intermittent (repetition of strong → weak). For intermittent jets, a strong HI of 1 or less was repeated, so that the jets would not be interrupted. The push button 29, indicator lamps 32, 33, 34, and types of jets are as follows (Fig. 3).

When the push button 29 is pressed for the first time, the "weak" indicator lamp 32 lights up and a weak jet comes out from the jet port 21 (Fig. 3(a)).
．． Furthermore, when the push button 29 is pressed (for the second time), the display lamp 33 of ``strong'' lights up and the jet becomes ``strong'' (Fig. 3 (b).
)). Furthermore, when the push button 29 is pressed (for the third time), the "intermittent" indicator lamp 34 lights up, and the jet becomes a jet that repeats "strong" and "weak" (FIG. 3(C)). Furthermore, push button 29
Pressing (fourth time) stops operation (Fig. 3 (d)). FIG. 4 shows an embodiment in which the jet operation mode can be displayed. A case (circuit cover) 12 in which the light guides 32, 33, 34, which serve as indicator lamps on the outer surface, are made non-contact with the indicator lamps, that is, LEDs 35, 36, 37 on the control circuit 10, and which houses the control circuit 1o. The display is made possible by sealing water with an O-ring 38 and clamping and fixing it between the front case 1 and the circuit cover 12.

Reference numeral 39 indicates a plaque.

〔Effect of the invention〕

According to the present invention, body parts/conditions (stiffness, muscle pain, etc.)
At the same time it is possible to choose the jet flow depending on
By starting from a low level, you can physically soften the shock caused by sudden changes. By repeating intermittent operation from strong to weak, the motor does not stop running, thereby alleviating stress when starting the motor and reducing starting current.

In addition, the structure has a case that houses the control circuit and a water-sealable light guide (indicator lamp on the outer surface) that does not make contact with the indicator lamp (LED) on the control circuit, so the operation mode can be changed easily. Now you can check.
