Device for oral hygiene working with water jet

The invention relates to a device for the oral hygfene for Cleaning the teeth and massaging the palate tissue and in particular an improved device through which an intermittent pulsating water jet is formed.

The use of a water jet with a small cross section and with intermittent pulses has been shown to be effective for removing particles to remove between the teeth and massage the palate tissue. It has proven to be particularly effective here To remove premed materials from the area of the tooth necks. The inventive The device is an improvement on the device of US Pat. No. 3,227,158.

The object underlying the invention is to create an improved device for oral hygiene that works with intermittent liquid impulses.

According to the invention, a corresponding device is created, which has a simple and compact structure, as well as light and accurate can be put together.

The device according to the invention has an improved arrangement through which the abrasion and vibration are held back during operation. ·

Furthermore, the device has an improved fluid connection between a pump and a detachable reservoir

The device according to the invention also has an improved one Arrangement for isolating the motor and the electrically excited parts from the fluid system.

The device according to the invention also has an improved one Arrangement, by which the Y / ffects of incorrect axial alignment and the lateral driving forces of the back and forth moving parts are largely halted. The device according to the invention also has an improved arrangement for controlling the device and for jäins üellen the kinetic energy of the impulses formed by it V / water currents.

Briefly outlined, the inventive device for found hygiene has a main pump unit for the formation of jf-ilissigkeitsimpulses with a speed of about 1200 impulses and with sufficient kinetic energy of each impulse in such a way that the palate tissue is pressed down, with a sufficient aostand between the individual pulses are present in such a way that the tissue can return to its original position. Me pulses are formed by a nozzle whose cross-sectional area is on the order of 0.8 mm. The pump is driven by an electric motor and has a small cylinder with a piston reciprocating therein, which is driven by a scotch yoke drive. A connection is provided between the piston and the drive, by means of which the action of the imprecise lateral and axial direction and the lateral drive forces in vibration are largely stopped, and the unit is controlled by a single handle which is arranged in this way that the motor switch is operated under starting or inoperative etzen the device wad is still arranged so that the pressure of the pump

^The result is that when the lole 25 moves back and forth, the same liquid is sucked in through the inlet opening 30, and when the opposite stroke occurs, the liquid is forced out through the outlet opening 31. The operation of the pump is such that the daily force of the liquid to be dispensed maintains the outward flow during the inlet tube of the piston and liquid is passed through

the inlet port 30 is supplied without the liquid being withdrawn from the outlet port.

The piston 25 is driven by operating a motor 35 with two idols, which are shielded, an oil motor 36 being connected in such a way that it drives a pinion 37 which meshes with a driving gear 38, the one cylindrical extension 4 ^l - which extends through a circular opening in a partition wall or motor plate 41, which is arranged in the interior of the housing 10.

The motor 36 is rotatably arranged on a stationary part 42 on bearings 43 and 44. The lower bearing 44 is rigidly connected to the xtotor and to the xiitzel 37. The stationary / rush 42 extends SiCN by a holder, see the reference numeral 45 "is carried out to the partition wall 41> by the dieseloe at the other end.

The piston 25 is' with aem drive part 46 ÜDer a provided with a head projection 53 ver bound, which is formed on the piston 25 and a complementary Has recess 54 which is formed in the end of the drive part 46. The recess 54 is rit an elongated Schlit2 55, namely at the upper end, as shown in FIG. 3 shows, through which the head part 53 during the assembly of the Mechanism can be used.

such that both lateral and angular movement the axis of the piston 25 with respect to the axis of the drive part 46 are possible. This relative movement is x sufficient to produce a incorrect angular alignment as well as a parallel one, however offset, incorrect alignment between the axis of the bar «« Pump bore 24 and the axis of movement of the drive part 46 compensate. This relative movement is also sufficient to the transmission of noticeable lateral movements from the drive part 46 to prevent the piston 25. As a result, assembly of the pump is made simpler and more efficient Wise care will be given to the required alignment of the piston and the drive part 46 such that a vibration and abrasion are restrained and the pump operates smoothly and reliably.

For example, a pump is shown in the drawings Manner constructed, the cylinder having an inner diameter of about 8 mm, with the other parts practically the in have proportional sizes as shown in the drawings. The diameter of the local cylinder parts of the head 53 amount to 0.8 mm smaller than the width of the corresponding part of the recess 54 and the length of the head of the extension 53 is on the order of 0.13 mm smaller than the depth of the corresponding part of the recess 54. In this arrangement found that the piston did not; the lateral thrust Must be carried by the movement of the bootch-yoke mechanism be generated. Furthermore, the piston is not required to be used as a bearing for the drive mechanism serves.
