2. It is composed of a sprinkler plate 95 with bristle bundles planted on the outer periphery and a water spout 96 on the inner periphery side of the bristle bundle group, and a brush stand 97 with bristle bundles planted on one side.

The brush stand 97 is connected to the rotary disk 92 via a rotating shaft 93, and the water flow introduced from the inlet 91 applies rotational force to the rotary disk 92 via the impeller 94, and the bristles are sent through the spout 96. By being supplied to the bundle group, washing can be performed while rotating.

(Problem to be solved by the invention) In the conventional rotating fountain brush shown in FIG.
Since the brush stand 97 is directly connected to the brush stand 97, it is necessary to introduce a large amount or high pressure of water in order to increase the rotation speed of the brush stand 97, which has increased in weight due to water content, to an appropriate rotation speed for cleaning. .

It is characterized in that the discharge port 12, the water channel 13, and the jet port 31 form, in this order, a flow path for water that drives the rotary disk.

In other words, the idea was that the rotational energy obtained from the water flow could be effectively transmitted to the brush stand via gears.

Although various forms of this gear can be considered, we adopted a planetary gear that can effectively accommodate a plurality of gears in a limited space.

(Operation) The water flow introduced into the pedestal collides with the impeller provided on the outer periphery of the rotary disk housed in the pedestal, and a thrust force is applied thereto to rotate the rotary disk. The rotary disk meshes with the planetary gear train through a spur gear provided on the rotating shaft, and the planetary gear train is further connected to the brush stand through its revolving shaft.
The rotational force of the rotary disk is easily transmitted to the brush stand.

(Example) An example of this invention will be described based on FIGS. 2 to 5.

FIG. 2 is a perspective view showing the structure of one embodiment of the present invention.

In Fig. 2, 1 is a pedestal, 2 is a rotary disk, 3 is a watering plate, 4 and 5 are planetary gear trains, 6 is a gear pedestal, and 7
is a brush stand.

The pedestal 1 is a housing part for the rotary disk 2, and because it derives rotational force from the water flow, there is no need to particularly change the structure of the pedestal of the prior art.

The rotary disk 2 has an overall disk shape (more specifically, an upside-down silk hat) and has one rotating shaft at its center. The rotating shaft 20 protrudes by an appropriate length in the vertical direction of the disk surface, and a spur gear is attached to the upwardly protruding portion (when the rotating shaft is fixed to the rotating disk; conversely, If the spur gear is integrally molded with the rotary disk, the rotary shaft may be inserted into a hole provided in the center of the two former parts, and the downwardly protruding portion connects to the pedestal. Attached to the center (tubular receiving member 16 provided at the center of the pedestal)
). A large number of impellers 22 are installed at the lower part of the outer periphery of the rotary disk 2 (corresponding to the brim of a silk hat).
(The impeller is vertically disposed radially around the rotation axis at a portion corresponding to the brim, forming a turbine blade).

The sprinkler plate 3 has a disk shape and has a hole 30 in the center of the bottom surface large enough for the spur gear 21 attached to the rotating shaft 21 to pass through, and its purpose is to serve as a brush stand 7.
There is no need to particularly change the prior art sprinkler plate and its structure because of the provision of a supply path for washing water to the sprinkler plate.

The planetary gear train 4 consists of one gear fixed platen 40 and three gears 41 of the same size. The gear fixing plate 40 is disc-shaped and has a hole 42 in its center.
A spur gear 43 having a shaft hole with the same diameter in the center as this perforation 42 is fixed to the gear fixing plate above the gear fixing plate with the same shaft center. Three protruding shafts 44 of appropriate length are arranged on the lower surface of the gear fixing plate at the vertices of an equilateral triangle whose center is the center of the perforation 42. Further, a shaft hole 45 having a diameter slightly larger than the diameter of the protruding shaft 44 is provided at the center of each gear 41, and by fitting this shaft hole to the protruding shaft 44 on the gear fixing plate 40, the gear 41 can be fixed as a gear. It is attached to a fixed platen 40.

Similarly to the planetary gear train 4, the planetary gear train 5 is also
One gear fixed plate 50 and three gears 51 of the same size
It consists of A protruding bar 52 having an appropriate length and a hexagonal cross section is provided on the center upper surface of the gear fixing plate 50. A hole 53 having a diameter slightly larger than the rotating shaft 20 of the rotary plate 2 is provided at the lower center of the protruding bar 52 . Further, three protruding shafts 54 are provided on the lower surface of the gear fixing plate 50, and the three protruding shafts 54 are similarly arranged in an equilateral triangular distribution with the center of the perforation 53 as the center. The structure of the three gears 51 is the same as that of the planetary gear train 4 described above, and is attached to the protruding shaft 54 of the gear fixing plate 50 in a fitting structure.

The gear pedestal 6 has a silk hat shape, and teeth 61 of an internal gear are installed on the inner surface of the peripheral wall 60.
At the center of the gear pedestal 6, there is one perforation 62 having a diameter slightly larger than the protruding bar 52 of the gear fixing plate 50.

There is a hexagonal perforation 70 in the center of the brush stand 7. The shape of the perforation 70 is made to match the cross-sectional shape of the above-mentioned protruding bar 52, and the protruding bar 52 is inserted into this perforation 70 and the brush stand is removed. can be fixed to the planetary gear train 5. Incidentally, a bundle of brush bristles is attached to the upper surface of the brush stand 7 and used for cleaning.

3A is a perspective view of the planetary gear train 5 assembled into the gear pedestal 6, and FIG. 3B is a perspective view of the planetary gear train 4 assembled into the gear pedestal 6, viewed from below in FIG. be.

The combination of the planetary gear trains 4, 5 and the gear pedestal 6 is an important part of the present invention, and the method of assembling it will be described in detail below.

As shown in FIG. 3A, the protruding bar 52 of the gear fixing plate 50 is connected to a perforation 62 provided at the center of the gear pedestal 6.
and attach the gear fixing plate 50 to the inside of the gear pedestal 6, which is turned upside down from the state shown in FIG. 2, so that both plate surfaces are tightly attached. Further, three gears 51 are respectively attached to three protruding shafts 54 on the gear fixing plate 50. At this time, the teeth of the three gears 51 are connected to the internal gears 6 provided on the inner peripheral surface of the gear pedestal 6, respectively.
It must be installed so that it meshes well with tooth 1. In this manner, when the gear fixing plate 50 rotates around the protruding bar 52, the three gears 51
It revolves in accordance with this (the locus drawn by the protruding shaft 54 becomes the orbit of the gear group - apart from the width).
Moreover, the three gears 51 are the internal gears 61 of the gear pedestal 6.
Because it is interlocked with the Earth, it also rotates on its axis at the same time as it revolves. This completes the planetary gear pattern.

When the assembly of the planetary gear train 5 is completed, as shown in FIG. and the teeth of the three gears 51 of the planetary gear train 5 mesh well with each other. In this manner, when the gear fixing plate is turned, three gears 51
rotates on its own axis via the spur gear 43 and revolves by meshing with the internal gear 61, and as a result, the gear fixing plate 50
also rotates at the same time. Furthermore, if the three gears 41 are respectively attached to the three protruding shafts 44 of the gear fixing plate 40 in the above-described manner so that the teeth of the three gears mesh well with the teeth of the internal gear 61 on the inner periphery of the gear pedestal, The gear group can simultaneously revolve (the locus drawn by the protruding shaft 44 is the orbit of the gear group, apart from the width) and rotate.

FIG. 4 is a cross-sectional view of a state in which the gear pedestal 6 incorporating the planetary gear trains 4 and 5 and the brush pedestal 7 are coupled.

The cross sections of the protruding bar 52 of the gear fixing plate 50 and the perforation 70 of the brush stand 7 are both hexagonal so that they can be fitted into each other. 52), and the brush stand 7 also rotates accordingly.

FIG. 5 is a perspective view of a state in which the rotary disk 2 and the sprinkler disk 3 are assembled on the pedestal 1.

Finally, the part shown in FIG. 4 and the part shown in FIG. 5 are joined in the following manner.

The rotating shaft 20 of the rotary disk 2 is connected to two gear fixed plates 40.
and 50 into the boreholes 42 and 53 (the shaft is inserted into the borehole). In addition, a rotary plate 2 protrudes through a perforation 30 provided at the center of the sprinkler plate 3.
The teeth of the spur gear 21 and the three gears 4 of the planetary gear train 4
Make sure it meshes well with tooth 1. Then, when the turntable 2 rotates (that is, the spur gear 21 rotates), the spur gear 21 rotates between the three gears 41
The gear fixing plate 40 can be rotated by causing the gear group to rotate on its own axis and further to revolve the gear group by meshing with the gear group and the internal gear 61.

When using the rotary fountain brush of this embodiment, water is introduced from the inlet 11 of the base 1 (the introduced water is ejected in the tangential direction of the rotary disk 2. Water pressure is applied to the impeller 22 of the rotary disk 2). It works, and thrust is generated there.
The rotary disk 2 rotates. When the rotary disk 2 rotates due to this hydraulic action, the spur gear 21 on it revolves the three gears 41, and thus the gear fixed disk 40
starts rotating. The three gears are gear pedestal 6
Since the three gears are meshed with the internal gear 61, the three gears rotate while revolving. Similarly, when the gear fixed plate 40 rotates, the three gears 51 can be made to revolve and rotate by the spur gear 43, and the gear fixed plate 50 is further rotated, thereby simultaneously rotating the brush stand 7. I come to do it.

Although the above embodiment uses two sets of planetary gear trains, it is of course possible to use only one set of planetary gear trains. however,
The effectiveness is inferior to that using two sets of planetary gear trains. Also, of course, more than one set of planetary gear trains can be used. Although the effect would be better, the structure was too complicated, so the inventor adopted two sets of planetary gear trains and was able to obtain a satisfactory and considerable effect.

In addition, the water poured from the inlet 11 of the pedestal 1 is
After applying rotational force to the rotary disk 2 via the impeller 22, it passes through the discharge port 12 and enters the water channel 13 defined by the inner circumferential wall 14 and outer circumferential wall 15 of the pedestal 1 and the bottom circumference of the sprinkler disk 3. Through the spout 31 provided to open into the water channel, the hair is supplied to the brush stand 7 and the groups of hair planted in the holes 33 on the upper surface of the peripheral part 32 of the sprinkler plate 3, and used for cleaning. .

[Effects of the invention] In the present invention, the rotational force of the rotary disk 2 is effectively transmitted to the brushes 7 by the action of the planetary gear train, so high water pressure is not required to drive the brush stand 7, and the amount of water used is reduced. This results in a reduction in water consumption and a water saving effect.
