Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a floor nozzle for electric/claw cleaners equipped with a rotating bluff.

Conventional configuration and its problems Conventionally, in this type of bed nozzle, -ε rotating brushes have generally had brush bristles planted on the outer circumferential surface of the rotor.
The overall diameter was quite large. Therefore, the height of the floor nozzle inevitably becomes large, which becomes an obstacle when cleaning underneath furniture and the like. In order to solve this problem, I am thinking of shortening the length of the 127 hair, but this lifting platform has a plano/puffer effect (127
There was a fundamental problem as a floor nozzle: the elasticity of the bristles reduced the ability to scrape up the carpet surface, reducing cleaning performance.

Purpose of the Invention The present invention overcomes these conventional drawbacks.
While maintaining a good plano/puffer effect, the rotating brush and eventually the floor nozzle are made smaller, and the brushing action (brushing action ``1'') is expanded.

Structure of the Invention The present invention provides a rotor with a concave groove formed in the longitudinal direction ('C), a groove bottom 1 with round bristles, and an external surface other than the groove at both ends of the rotor. A rotary brush is constructed by installing each of the 'C secondary brushes/', and the rotary brush diameter is made smaller by the length of the king brush bristles facing inside the concave flange, and the plan is sufficient for the brushing action. In addition to ensuring the length of the bristles, the brushing action is also performed at both ends of the rotating plan.

Example Examples thereof will be described below with reference to the accompanying drawings.

In Figures 1 to 3, floor nozzle 4: body 16-i bumper 2
It is obtained by joining the upper and lower body members 3 and 4 through a The turbine chamber 7 is separated from the I suction chamber 6 by a partition wall 8.
The rear part with the trench opening 9 is set in an arc shape.

A rotating brush 12 is provided on both side walls of the suction chamber 6, with a part of the main brush bristle 11 and the brush bristle 11' implanted at 10' projecting to the outside through the suction port 5, Both III of the rotating brush 10-・Protruding 1llll
12', a fixed brush 13 installed parallel to the rear of the suction port 5, and 14.15 installed at the front and rear of the floor nozzle body 1 in order to position the suction port 6 at a constant distance from the surface to be cleaned. It is a wheel installed on the

Reference numeral 16 denotes a substantially semi-cylindrical suction joint that rotatably slides on the rear inner surface of the turbine chamber 7, and the connection port 17 (i) is formed from a part of the peripheral wall of the suction joint 16. 16 protrudes outward from its side wall, and an fc shaft 18 and a hollow shaft 19 are pivotally supported on both side walls of the turbine chamber 70.The suction joint 1e rotates while closing the rear opening 9 of the turbine chamber 7. However, due to this, connection port 17

22 is a turbine installed in the turbine chamber 7, with a part of the outer periphery surrounded by the suction joint 16, and from -01II there is a shaft body that penetrates through the hollow single shaft 19 of the suction joint 16 and protrudes outside the turbine chamber. 23 is integrally provided. 24 is a bearing of the shaft body 23 fixed to the floor nozzle body 1, and 25 is a small pulley 26 provided at the tip of the shaft body 23 and the rotation plan 10.
This is a power transmission belt stretched between the dog pulley 27 provided in the That is, the rotation of the turbine 22 is slowed down and transmitted to the rotating blade 10.

Further, the turbine 22 is provided offset to one side of the turbine chamber 7 (right side in FIG. 1). 28 and 29 are two ventilation holes formed in the partition wall 8, and one of the ventilation holes 28 is for the turbine 2.
The other vent port 29 is located opposite the lower half of the turbine 22 and directly faces the connection port 17 of the suction joint 16, not facing the turbine 22. 3o is a switching lever KL biased in one direction by a spring 31;
An opening 33 is formed in the partially protruding shielding plate 32, which communicates with either one of the ventilation holes 28 and 29. 34 is a knob of the switching lever 30, and 35 is a leaf spring that cooperates with a protrusion 36 formed on the switching lever 30 to maintain the operating state of the switching lever 30 against the spring 31.

The rotation range of the suction joint 16 relative to the floor nozzle body 1 is regulated by the distance between the stoppers 37 and 38 formed respectively. When sliding to the right in FIG. 1 and making the opening 33 of the a-shield 32 communicate with one of the vents 28, the suction air flowing from the suction port 5 to the suction chamber 6 to the vent 28 flows into the turbine 22. and then the suction joint 16
It flows through the connection port 17 - connection tube 20 - extension pipe - hose and reaches the vacuum cleaner. Therefore, the turbine 22
rotates, and its rotational force is transferred to the rotating bra/10 after deceleration.
: Reached.

Furthermore, when the opening 33 of the shield plate 32 is communicated with the other vent 29 via the switching lever 30, the suction air flows through the turbine chamber 7 regardless of the turbine 22 and reaches the suction joint 16. Therefore, the turbine 22 and the rotating plano 10 do not rotate.

During cleaning work, the floor nozzle body 1 can move up and down with respect to the suction joint 16, that is, it can be raised and lowered, so no matter what the worker's posture is, the suction port 5 of the floor nozzle body 1
is opposed to the surface to be cleaned and ensures dust collection.

Now, as mentioned earlier, the rotating brush 1Q has a rotor 10'
The main 797 hairs 11' and the sub plan 11' are implanted in the rotor 10', and its structure (4 m39 is formed in the longitudinal direction of the rotor 10', and the main 197 hairs are installed at the bottom of this groove 39). 11
It is the same as the one planted with. Of course, king brush hair 1
1 protrudes from the outer circumferential surface of the rotor 711'. Also, the auxiliary planar bristles 11' are implanted on the outer circumferential surface of the rotor 10' at both ends of the grooves other than the three concave grooves. To explain further, since the royal brush bristles 11 have shafts 12' embedded in the center of both ends of the rotor 11', the shafts 12'
Both ends R(, (r, r
However, due to the same 1II1h12', the planting depth is extremely shallow f:r, and the main brush bristles 11 cannot be used substantially.

Therefore, if there is only the main 797 bristles 11, there will be areas without brush bristles at both ends of the rotor 10', and the rotation plan 1o
The plano 7 nog width is narrower than the length.

However, in the above embodiment, the sub-brush bristles 11' are implanted on the outer periphery of the rotor io' except for the concave grooves 39 at both end portions. Here, even if the secondary bra/bristle 11' is planted halfway to the center of the rotor 10' from the position where the concave groove 39 does not exist, the planting depth will be sufficient. With the above configuration), the diameter of the partial rotary plug 10 facing into the concave groove 39 of the main brush bristles 11 can be changed (and the overall length of the regenerative bluff bristles 11 is the same as the conventional one). The brushing effect can also be improved since sufficient amount can be removed in the same way as in the case of cleaning.Furthermore, the sub-plan bristles 11' allow brushing to be carried out over the entire length of the rotating brush 10, thereby removing uncleaned areas. can be eliminated.

In the above embodiment, a turbine was used to drive the rotating brush, but it is also possible to use a motor, and the drive source is not specified.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention includes forming grooves in the rotor, and forming royal brush bristles on the bottom of the grooves, and sub-brushes on the outer peripheral surface other than the grooves at both ends of the rotor. By using a rotary plan that has been installed, the following excellent effects can be expected. It can be easily cleaned even under furniture, etc., and the cleaning ability of the floor nozzle is improved to eliminate defects.

11 The length of the main 197 hair itself is sufficient, and a better plano/puffer effect can be obtained.

■1 The small rotation plan diameter allows the rotation torque to be reduced. Therefore, the drive source that rotates it only needs to be of low output, and as a result, the floor nozzle can be made even thinner and more compact, which is also very advantageous in terms of cost and weight reduction.

■ The subplan bristles make use of the entire length of the rotor to create a plano 7 link, which ensures that no cleaning residue is left behind.
Allows for efficient cleaning.
