Description

[Detailed Description of the Invention] Industrial field of use [Technical Field] The present invention relates to an oral cavity cleaner that discharges water by a diaphragm valve system for cleaning the oral cavity.

2. Description of the Related Art Oral cleaners that use water pressure to discharge water into the oral cavity for cleaning the oral cavity, diaphragm valve pump system, air pump system, cylinder / piston system,
Various types are known, including a piezoelectric vibration type.

Of the above, the one using the diaphragm system is
For example, there is Japanese Utility Model Laid-Open No. 56-116017. In the invention of this publication, when converting the rotational motion of the motor into a linear reciprocating motion by the drive rod via the eccentric mechanism, the drive rod is divided into a main link rod and a follower rod via a hinge and a follower rod. Is fitted into the guide cylinder to change the movement of the follower rod directly connected to the diaphragm into an accurate linear reciprocating motion, thereby preventing the diaphragm from being damaged.

Japanese Unexamined Patent Publication No. 56-72860 also discloses an oral irrigator adopting a diaphragm system, and discloses a mechanism capable of continuously changing the stroke range of the operating rod.

Problems to be solved by the invention The diaphragm method is not required to have water pressure, the device is relatively simple, it is hard to cause a failure, and there is no phenomenon in which discharge due to air entrapment is impossible. It is considered that there are many advantages over other methods.

However, in the conventional diaphragm type oral cleaners such as those disclosed in Japanese Utility Model Laid-Open No. 56-116017 and Japanese Patent Application Laid-Open No. 56-72860, the stroke of the drive rod is set to obtain a strong ejection force. It must be made large, but if it is designed that way, the diameter of the diaphragm,
It cannot fully meet the demands for compactness of the eccentric mechanism, drive rod, etc., and because the discharge water is limited to the pulse flow, it is easy to use, removes dirt between teeth and stimulates gums. There were problems such as not being completely satisfied with the points.

The present invention has been achieved as a result of intensive studies aimed at eliminating the drawbacks of the diaphragm valve system while making the most of it.

Means for Solving the Problems The oral lavage device of the present invention converts the rotational movement by the motor (1) into the linear reciprocating movement by the drive rod (3) through the eccentric mechanism (2), and the drive rod (3 ) Of the diaphragm valve (4) disposed on the other end side of the cleaning device to discharge the cleaning water by the vibration operation, the first driving rod (3) as the driving rod (3).
a) and a plurality of rods composed of a second drive rod (3b) are used, and the first diaphragm valve (4a) and the second diaphragm valve (4a) corresponding to the drive rods (3a) and (3b) are used as the diaphragm valve (4).
It is characterized by using a plurality of valves consisting of a diaphragm valve (4b).

The present invention will be described in detail below.

In the present invention, as in the conventional diaphragm valve type oral lavage device, the rotary motion by the motor (1) is changed to the eccentric mechanism (2).
Is converted into a linear reciprocating motion by the drive rod (3) via. A diaphragm valve (4) is arranged on the other end side of the drive rod (3), and washing water is discharged by vibrating the diaphragm valve (4).

For the power source, it is desirable to use both a home power source and a battery, and a transformer (5) is provided for the former.

According to a characteristic construction of the present invention, a plurality of rods including a first drive rod (3a) and a second drive rod (3b) are used as the drive rod (3), and the drive rod (3a) is used as a diaphragm valve (4). ), (3
The purpose is to use a plurality of valves including a first diaphragm valve (4a) and a second diaphragm valve (4b) corresponding to each of b).

Then, in this case, the vibration operation of the first diaphragm valve (4a) by the first drive rod (3a) and the vibration operation of the second diaphragm valve (4b) by the second drive rod (3b) are mutually synchronized or non-synchronized. Or set to be switchable between tuning and non-tuning.

As washing water, in addition to washing, deodorant, fragrance, germicide,
Water to which a mouthwash or the like is added is used. Wash water
Place it directly in the suction port (6) of the washer while it is in the tank, or in the cup etc.
Contact (6) with a hose.

In order to discharge the wash water into the oral cavity, a flexible hose (8) is attached to the discharge port (7), and a handle portion is attached to the tip of the hose (8).
(9) is provided, and the handle (9) is provided with a nozzle (10). nozzle
It is desirable that (10) be prepared so that it can be replaced with several kinds having various diameters.

The action and the effect of the invention The rotary motion by the motor (1) is the first through the eccentric mechanism (2).
It is transmitted to the drive rod (3a) and the second drive rod (3b).

By the reciprocating operation of the first drive rod (3a), the first diaphragm valve (4
a) oscillates and the second drive rod (3b) reciprocates to move the second
The drive rod (3b) vibrates.

When the vibration operation of the first diaphragm valve (4a) by the first drive rod (3a) and the vibration operation of the second diaphragm valve (4b) by the second drive rod (3b) are synchronized, the drive rod (3a ), (3b) Even if the stroke is small, a strong ejection force can be obtained as a pulsed flow. Since the stroke can be reduced, the required output can be obtained even if the diameter of the diaphragm, the eccentric mechanism, the driving rod, and the like are reduced, and the cleaner can be made compact.

By providing a time lag for these vibration operations and setting them in a non-synchronized state, a pulsating flow can be obtained, so that a feeling of use different from that of a pulsed flow, dirt removability, or gingival irritation can be obtained.

Particularly, when the vibration operation is configured to be switchable between tuning and non-tuning, the user can select the pulse flow or the pulsating flow according to the purpose of use, so that the function can be expanded.
