Description

DETAILED DESCRIPTION OF THE INVENTION Various types of blow heads are available for use in showers that produce pulsating mist.

For example, such heads are disclosed in US Pat. No. 1,446,887, US Pat. No. 1,609,047, US Pat.
No. 3587 and No. 3762648. Although most of the patents listed here only produce a pulsating mist, some can be adjusted to produce a steady spray or a pulsating mist. In this case, the spray head becomes complicated and adjustment to select a desired spray may be difficult depending on the usage conditions. This invention aims at improving a pulsating jet type shower light fog head, and its objects are as follows. First, a new hand-engaging handle circle with an exposed periphery that is easy to rotate relative to the housing of the spray head to produce a coarse pulsating mist or a steady fine spray. When using the board, provide a fog head.

Second, the water is rotated to drive a rotor with a novel configuration that has an open part and a closed part that sequentially passes through a ring-shaped jet boat, discharging the water intermittently or in a pulsating manner. To provide a lantern head that

Third, the means for generating a fine spray pattern, such as a mist head for other purposes, is affected by the movement of the rotor, but the provision of multiple passages minimizes pulsations. To provide a counterfeit head having a direction.

Fourthly, as a mist head for the above-mentioned purpose, a fine mist passage is formed by a series of nest-like rings, each having a set of circumferential grooves covered by the opposite walls of the next ring; To provide a mist head in which each ring is easily separated for washing rice bran.

Referring first to FIGS. 1-5, a pulsating jet mist head has a housing 1 which, in the configuration shown in FIG.

The housing forms a chamber 3, the central axle 4 of which is secured by a mounting bolt 5. The front leg of the chamber 3 is closed by a plate 6 with a peripheral edge 7 heat-sealed or otherwise fixed to the housing.

The plate 6 has a radially inner set of holes 8 and a radially outer set of holes 9, each set having three holes in the illustrated configuration. A set of holes 8 inside the plate 6 corresponds to a spray supply boat, and a set of holes 9 outside the plate 6 corresponds to a jet spray supply boat.

The plate 6 has a flat outer surface, on which the handle disk 10 is mounted.

The wall 11 of the disk 10 faces the plate 6 and is sealed thereto by a circumferential sealing ring 12. The circumferential green 13 of the handle disc projects radially beyond the plate 6 and the front end of the housing 1. The drop edge 13 also extends to the front side of the wall 11. A groove 13a (shown in FIG. 3) is provided in this green circumference, and the handle disc 1 is
Grab the 0 and make it easier to turn. The armpit 11 is provided with a set of radially inner holes 14 positioned to align with the holes 8 .

This is the spray nozzle. The shaft 11 is also provided with a set of radially outer holes 15 in alignment with the radially outer holes 9 . Hole 15 forms a jet nozzle. The central part of the wall 11 surrounding the hole 8 forms a recessed area 16 with a tapered peripheral wall 17 .

Akebono disks 18 and 19 that overlap in the axial direction
, 20 cover the recessed area 16. A ring-shaped groove 21 extending in the axial direction is provided on the outer periphery of each disk, whereas the wall facing it is smooth, so that the groove 21 has the same diameter.
form a ring-shaped spray nozzle. The mounting bolt 5 passes through the wall 11 and the inner nut 22 and washer 23 are fitted.

As a result, the wall 11 is attached to the plate 6, and the housing 1
A predetermined degree of resistance to the rotation of the handle disk 10 against the rotation of the handle disk 10 is obtained. The mounting bolt 5 also has an outer nut 24 which engages the radially inner atomizer disk 20 to hold it in place. In order to limit the rotation of the handle disc 10 with respect to the housing 1, an arcuate slot 25 is provided in the circumferential green 7 of the plate 6, and an arcuate projection 26 shown in FIG. 2 is provided in the corresponding area of the handle disc. establish.

A rotor 27 is installed inside the chamber 3.

The rotor 27 has a base plate 28 and its hub 29 is loosely supported on the central axle 4 between opposite shoulders 4a, 6a. The base plate 28 is also connected to the hub 29 and three circumferential walls extending in the same direction, the hub and the walls being connected by a radial impeller web 31. The substrate is provided with an arcuate hole 32 radially overlapping the outer hole 15 and partially overlapping the inner hole 14 .

Preferably, the substrate is slightly arched and curved away from the annular recess 33 to form an annular side channel opening with the outer periphery of the substrate 28. In the configuration shown in FIGS. 1 to 4, the handle 2 is provided with a supply V supply passage 34, which discharges water into the chamber 3, hits the baffle plate 35, rotates the incoming water, and when rotated, the web 31 to rotate the rotor 27. The operation of the embodiment of the pulsating jet counterfeiting head shown in FIGS. 1-5 is as follows.

When it is desired to use a pulsating jet, the handle disk 10 is set as shown.

That is, as shown in FIG. 3, the radially outer holes 9 align with the radially outer holes or jet holes 15. The rotation of the rotor 27 causes the arcuate slots 32 to pass through the holes 9 one after the other, allowing water to freely pass through the slots 32 and align the holes 9,15.
directly into the water, producing a powerful jet of water. Hole 9
is covered by the substrate 28, direct dispensing is shut off. However, due to the gap between rotor 27 and plate 6, a reduced flow occurs. For this reason, the water exits as a jet continuously, but the force of the jet increases intermittently. When the handle disc 10 is turned and the holes 8, 14 are connected, water is discharged into the recessed area 16 and from there into the spray groove 21.
pass through.

Although some pulsation does occur, it is slight due to the swaying of the flow in the area behind the discs 18, 19, 20 and because of the small size and large number of grooves 21. The pattern of the jet spray is related to the shape of the jet nozzle.

As shown in Figure 3, the discharge end of the jet orifice is
As shown at 6, it can be extended radially inward.
This causes the jet stream to be deflected and scattered slightly radially outward. A small inner boss 37 as shown in FIG. 5 is provided at the outlet end to allow for desired curvature. Additionally, the jet nozzle may be tapered in either direction. Furthermore, each jet stream need not be identical. Thus, it can be seen that it is possible to adjust the pattern of the jet stream in advance to achieve the desired effect. It will be appreciated that some wobbling will occur because the rotor is loosely mounted.

This has been found to be advantageous in altering the jet stream. This oscillation also appears to contribute to damping the pulsations when discharged through the diamond nozzle formed by the discs 18, 19, 20. It will be appreciated that since the handle disc 10 extends radially beyond the housing 1, it is easier to grip and turn the handle disc 10 by its peripheral edge 13. The embodiment shown in has a modified rotor 38.

Rotor 38 has a substrate 39, a hub 40, a peripheral wall 41 and radial webs 42 similar to the corresponding elements of rotor 27. As with rotor 27, webs 42 divide the rotor into eight parts, but instead of arcuate slots 32, six parts have holes 43 and the remaining two parts are closed. , further covered by a shallow arcuate boss 44 with a short radial extension 45 . The rotor 38 is mounted so that the boss 44 approaches the rear wall of the plate 6, as shown in the upper leg portion of FIG. The operation of rotor 38 differs from rotor 27 in that the clearance between boss 44 and radial extension 45 and plate 6 is small, as shown in FIG.

Therefore, at a given point in time, the flow through one hole 9 will be minimal, while the other holes will have full flow. Instead of the baffle plate 35, this variant arrangement is provided with a raised part 46 at the bottom of the chamber 3, and an arcuate slot 47 is formed between the raised part 46 and the wall of the chamber, so that the water can flow into the chamber 3. When it enters, it rotates or turns.

The raised portion 46 also has an elbow passage 48 whose discharge aligns with a tangentially oriented flow rate 49 so that water flows into the chamber 3.
and engages web 42 to keep rotor 38 in rotation. The baffle plate 35 or raised portion 46, arcuate slot 47 corresponds to the means for rotating the water. The housing 1 can be replaced with a housing 50 that is mounted on the wall.

This housing has a chamber 51 corresponding to chamber 3 and a central axle 52 corresponding to central axle 4 and adapted to receive a mounting bolt 5 . The central entrance chamber 53 is the mandrel 5
2 from the chamber 51, which is the rotor 3.
8 so that water hits the web 42.
A journal ring 55 is fitted to the rear end of the housing 50 and a threaded mounting ring 56 engages and seals with the journal ball 57.

The ball has an inlet passageway 58 and a standard fitting 59, partially shown in the figures. This is adapted to be threadedly connected to a wall-mounted supply v-tube, not shown.
The reaction of the rotor 38 to the water exiting the helical passage 54 is caused by the arcuate slots 47 and the tangentially oriented flow passages 4.
This is approximately the same as the rotor reaction to 9.

Although the invention has been described in detail, it is to be understood that the invention is not limited by the details described above, but rather by the scope of the claimed invention.
