Description

[Detailed description of the invention] Industrial applications The present invention relates to a floor nozzle for a vacuum cleaner.

This type of conventional floor nozzle body is easy to clean and dust-collecting for various surfaces to be cleaned such as floors, tatami mats, and carpets. In order to improve efficiency, the dust collection zone such as the plan is placed on the underside of the floor nozzle body so that the amount of the dust can be freely selected in several stages. Here, a conventional example of a configuration in which a dust collection band such as a plan can be moved up and down will be explained below.
As shown in FIG. 6, 1 is a floor nozzle body formed by combining upper and lower body parts 2 and 3, 4 is a dust collection band, a driving body, an operation knob 5, a dust collection band guide groove 6, However, a greasy elastic claw part 7 is formed, which is held at the top and bottom by the upper body member 2 and the lower body part 3, and is slidable in the direction of the arrow (horizontal direction). The dust collection band movable body 4 is fixed at each position by a resin elastic claw part 7.
The engagement 11 of the rib 8 formed on the upper body portion lA2 and the concave portion 9
10 is a dust collection band in which one end of the brush bristles 11 made of nylon or the like is sandwiched between sheet metals to eliminate the holding part 12. .13 is a dust collection belt holding frame which has a U-shaped cross section and holds and fixes the dust collection belt 10.The dust collection belt 10 is attached to the dust collection belt holding frame 1
The holding part 12 of the dust collection belt 10 is inserted from the side in the longitudinal direction of the dust collection belt 10, passing over the individual fixing claws 14 and slidingly inserted between the U-shaped lower surface part and the plurality of fixing lips 15. Immediately before the end of the holding part 12 contacts the fixing claw 14 on the opposite side from the insertion position, the terminal end of the holding part 12 passes over the fixing claw 14 and the insertion and fixation of the holding part 12 is completed.

The sliding holes 16 formed at both ends of the dust collection cloth holding frame 13
is fitted into a guide boss 17 formed on the upper body part 2,
It can be slid up and down. Reference numeral 18 denotes a sliding boss, which is slidably fitted into the dust collection band guide groove 6, and which prevents the dust collection cloth holding frame 13, i.e. the dust collection band, from moving horizontally when the dust collection phase drive body 4 moves. 10 is configured to move up and down.

The problem here is that when using the floor nozzle body 1, the user may drop the floor nozzle body 1 from a certain height onto the surface to be cleaned, or The movement of hitting the mask against pillars, walls, etc. was done unconsciously. However, shocks of various sizes are applied to the floor nozzle body 1 each time, and in particular, the dust collection zone 10 receives the most impact.

As described in the above configuration, the dust collection strip 10 and the dust collection cloth holding frame 13 are held and fixed in the longitudinal direction by the low-height fixing claws 14 that hold the end of the holding portion 12 of the dust collection strip 10. Moreover, when the end of the holding part 12 is cut with a knife, as shown in FIG. 6, the tip is generally pointed like the prow of a ship. Therefore, when an impact is applied to the floor nozzle main body 1, especially from the side, the tip of the holding part 12 scrapes the fixed claw 14 and gets over the guide boss 1.
7) (as shown in Fig. 6), this is a fatal malfunction for the floor nozzle body 1 in which the dust collection band 1° does not move up or down even if the operating knob 5 is operated. There was a problem. Furthermore, if the floor nozzle body 1 is dropped with the floor nozzle body 1 horizontal, the entire dust collection belt 10 will absorb the impact force, but if it is dropped at an angle, the impact force will be concentrated on both ends of the dust collection belt 1o. , causing extreme deformation of both ends of the brush bristles 11. Otherwise, there were problems such as damage to the sliding hole 16.

Purpose of the Invention The present invention solves these conventional problems.
The purpose of the present invention is to provide a structure that securely holds and fixes the dust collection band and also alleviates the impact force applied to both ends of the dust collection band.

Structure of the Invention The present invention is a floor nozzle body having a structure in which the protrusion length 3 of the dust collection band from the bottom surface of the floor nozzle body can be optimally selected for the surface to be cleaned, and the dust collection band and the dust collection band guide groove are held and fixed. The dust collecting band is press-fitted from the opening, that is, the upper surface, of the dust collecting cloth holding frame, which has a U-shaped cross section. By forming a space at both ends where the dust collection band fits, that is, by recessing both longitudinal ends of the U-shaped groove of the dust collection cloth holding frame, the impact force applied to the end of the dust collection band can be reduced. The dust collection belt is designed to allow absorption by moderately bending the ends of the dust collection belt, which prevents the dust collection belt from coming off in the longitudinal direction, and at the same time prevents deformation of the brush bristles at both ends of the dust collection belt, and dust collection examples. DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments thereof will be described based on the accompanying drawings. In FIGS. 7 to 13, 19 indicates the upper and lower body members 2.
