The sucked dust passes through the extension tube 1 and is accommodated in the dust collecting portion 23 in the handle portion 3 .

In addition, the dust collection part 23 may be the structure provided with the dust collection bag, for example, and may be the structure provided with the cyclone type dust collection part.

As described above, an electric vacuum cleaner is formed.

Next, the configuration of the suction tool 2 of the electric vacuum cleaner will be described with reference to FIGS. 2 to 5 .

Furthermore, in the following, for example, as shown in the paper surface of FIG. 2 , the side on which the extension tube connecting portion 6 of the inhalation tool 2 is disposed is referred to as the rear or upper side. side, and the opposite side is described as the front or the bottom. In addition, as shown in the paper surface of FIG. 3 etc., the left side when seeing the inhalation tool 2 from the front is demonstrated as a left side, and the right side is a right side. However, when the user holds the handle portion 3 while cleaning, when the user sees the handle portion 3, the above-mentioned right corresponds to the left side, and the left side corresponds to the right side.

FIG. 2 is a side view of the inhalation device 2 shown in FIG. 1 . FIG. 3 is a top view of the inhalation device 2 shown in FIG. 2 . FIG. 4 is a bottom view of the inhaler 2 . FIG. 5 is a perspective view of the inhaler 2 .

As shown in FIGS. 2 and 3 , the inhaler 2 of the present embodiment has an inhaler body 4 , a rotating body 5 , an extension tube connection portion 6 , and the like. The rotating body 5 is behind the inhalation tool body 4 and is rotatably connected to the inhalation tool body 4 . The extension pipe connecting portion 6 is fitted with a gap so as to be rotatable with respect to the rotating body 5 . Moreover, the extension pipe connection part 6 is to which the extension pipe 1 of a vacuum cleaner is detachably connected.

The inhaler body 4 is provided with a mound 7, the surface of the upper side of the mound 7 is formed from the front end to the middle part by a curved surface that gradually protrudes, and the part connected to the rotating body 5 from the middle part is formed at a predetermined height. formed.

Moreover, as shown in FIG. 4 , the inhaler 2 has a suction port 9 formed on the lower surface side of the approximate center (including the center) of the inhaler body 4 for inhaling dust.

Furthermore, the inhalation tool body 4 of the inhalation tool 2 of the present embodiment shown in FIG. 5 is, for example, about 16 cm in the longitudinal direction (front-rear direction), and about 6 cm in length in the short-side direction (left-right direction). form. again, inhale The device main body 4 has, for example, an arc-shaped recess formed in a range of about 3 cm in length from one rear end surface in the longitudinal direction toward the inside of the inhaler 2 . The rotating body 5 is arranged in the recessed part. Therefore, in the present embodiment, the upper part from the recessed part is referred to as "the rotating body arrangement space 10" and described below. In addition, the above-mentioned length is only an example, and it goes without saying that it can be designed with different lengths.

The inhaler main body 4 has a first concave portion 11 having a curved cross section below the rotating body arrangement space 10 . The first concave portion 11 includes flange-shaped seat portions 12 on both left and right sides. In this way, the rotating body 5 is rotatably connected to the first concave portion 11 at the rear end portion of the hill portion 7 of the inhaler body 4 .

Also, the side surfaces in the left-right direction of the rotating body 5 are formed with curved surfaces. Thereby, the rotating body 5 can slide on the curved surface of the first concave portion 11 of the inhaler body 4, or have a slight gap with the first concave portion 11, so that it can be rotatably connected. That is, the rotary body 5 is connected so as to be rotatable in the left-right direction of the inhaler main body 4 . That is, the rotating body 5 becomes capable of rotating from the direction of the arrow A to the direction of the arrow B shown in FIG. 5 , or from the direction of the arrow B to the direction of the arrow A. As shown in FIG.

Furthermore, as mentioned above, the rotating body 5 is rotatably connected to the extension tube connecting portion 6 . The extension tube connection portion 6 will be described in detail later. In this case, also in FIG. 5 , it can be seen that one end of the extension pipe connection portion 6 is arranged in the rotating body arrangement space 10 of the inhaler main body 4 .

As described above, the suction tool 2 of the electric vacuum cleaner is constituted.

Then, for the action of the rotating body 5 of the inhalation tool 2 (active ) will be described with reference to Fig. 6 to Fig. 8 .

FIG. 6 is a perspective view showing a state in which the rotary body 5 of the inhalation tool 2 shown in FIG. 5 is rotated in the arrow B direction. FIG. 7 is a perspective view showing a state in which the rotating body 5 of the inhalation tool 2 shown in FIG. 5 is rotated in the direction of the arrow A. As shown in FIG. FIG. 8 is a perspective view showing the operation of rotating the rotating body 5 of the inhaler 2 in the arrow C direction and the arrow D direction.

As shown in Figure 6, when the rotating body 5 is rotated in the direction of arrow B, the extension tube connecting portion 6 abuts against a seat portion 12 of the first concave portion 11 (in FIG. The pedestal portion 12 near the inner side (left side). Thereby, further rotation of the rotating body 5 in the B direction is restricted.

Also, as shown in FIG. 7, when the rotating body 5 is rotated in the direction of arrow A, the extension tube connecting portion 6 abuts against another pedestal portion 12 of the first concave portion 11 (in FIG. The pedestal portion 12 on the front side (right side) in the left-right direction). Thereby, further rotation of the rotating body 5 in the direction A is restricted.

That is, the rotating body 5 is from the state shown in FIG. 6 to the state shown in FIG. 7, or from the state shown in FIG. 7 to the state shown in FIG. move. Therefore, the rotating body 5 is connected to the inhaler main body 4 with an axis (not shown) extending in the front-rear direction of the inhaler 2 as a rotation axis. Thereby, the rotating body 5 rotates within an angle range of about 180 degrees in the left-right direction of the inhaler 2 with the rotating shaft as a fulcrum.

In addition, as shown in FIG. 8, the rotating body 5 has a rotating body opening 8, and the aforementioned rotating body opening 8 is opened from the rear of the rotating body 5 (shown in FIG. 8 ). Arrow D direction) opens to the front of the rotating body 5 (arrow C direction shown in FIG. 8 ). The extension tube connection portion 6 has a substantially hemispherical (including hemispherical) front end portion 6a (a portion of the extension tube connection portion 6 on the inhalation tool body 4 side). In addition, as long as the front-end part 6a of the extension pipe connection part 6 is rotatable, it can also be formed in substantially spherical shape (including spherical shape). Further, the rotating body 5 has a space formed inside to accommodate the substantially hemispherical (including hemispherical) tip portion 6a of the extension tube connection portion 6 so as to be fitted with a gap. In addition, in this embodiment, below, this space is called "the 2nd recessed part 13" and is demonstrated.

That is, the distal end portion 6 a of the extension tube connection portion 6 is fitted into the second concave portion 13 with a gap. Therefore, the extension tube connecting portion 6 is rotatable in the front-rear direction of the inhaler 2, that is, in the direction from the arrow C shown in FIG. 8 toward the arrow D, or in the direction from the arrow D toward the arrow C. Dynamically embedded with gaps.

In addition, in the above, although the front-end|tip part 6a of the extension pipe connection part 6 is made into the 2nd recessed part 13 of the rotating body 5 with a gap and demonstrated as an example, it is not limited to this. For example, other configurations may be used as long as the front end portion 6 a of the extension tube connection portion 6 is rotatably connected to the rotating body 5 .

Specifically, when the extension tube connecting portion 6 is rotated in the direction of the arrow C shown in FIG. 8 , as shown in FIG. 5 , the extension tube connecting portion 6 becomes approximately 90 degrees (including 90 degrees) The angle of the upright setting state. That is, by the rotation of the extension pipe connection part 6, the side surface of the front side of the extension pipe connection part 6 abuts against the front side of the opening part 8 of the rotating body. end 8a. Thereby, the extension tube connecting portion 6 is restricted from further turning in the direction of the arrow C shown in FIG. 8 at an angle exceeding approximately 90 degrees with respect to the inhaler main body 4 .

On the other hand, when the extension tube connecting portion 6 is rotated in the direction of the arrow D shown in FIG. The state of being inclined at an angle of about 40 degrees counterclockwise with respect to the ground (refer to FIG. 9 ). That is, by turning the extension pipe connection portion 6 in the direction of arrow D, the rear side surface of the extension pipe connection portion 6 abuts against the end of the rotation body opening 8 provided on the rear side of the rotation body 5 8b. Thereby, the extension tube connecting portion 6 is restricted from further rotation in the direction of the arrow D in FIG. 8 at an angle exceeding approximately 140 degrees relative to the inhaler main body 4 .

Furthermore, in the above-mentioned embodiment, although the example of restricting the rotation of the extension pipe connection part 6 relative to the inhalation tool body 4 exceeding approximately 140 degrees in the direction of the arrow D in FIG. 8 is described, the angle It is not limited to this, and it is also possible to make a structure which restricts a rotation in another angle range.

As mentioned above, the suction tool 2 and the electric vacuum cleaner provided with the suction tool 2 of this embodiment arrange|position the rotating body 5 in the rotating body arrangement|positioning space 10 of the suction tool main body 4. As shown in FIG. In addition, an extension pipe connection portion 6 is fitted into the rotating body 5 with a gap. Therefore, when the user holds the handle part 3 and pushes the suction device 2 of the electric vacuum cleaner forward, the user's force will definitely move towards the extension tube 1, the extension tube connection part 6, the rotating body 5 and the suction tool body 4. convey. Thereby, it is easy to push the inhalation tool 2 forward, and it is easy to clean electric vacuum cleaner.

Here, as long as the rotating body 5 slides on the upper surface of the first recess 11 provided behind the inhaler body 4 , the user's force is reliably transmitted from the rotating body 5 to the inhaler body 4 .

On the other hand, if there is a slight gap between the rotating body 5 and the upper surface of the first recess 11 provided behind the inhaler body 4, by making the rotating body 5 with an elastic material such as resin, When the user operates, the user's power will be transmitted to the rotating body 5, and the rotating body 5 will be elastically deformed, so that the rotating body 5 is in contact with the upper surface of the first concave portion 11, and the user's strength will be reduced. It is reliably transmitted from the rotating body 5 to the inhaler body 4 .

Moreover, even if the user holds the handle 3 and exerts a strong force to clean, the rotator 5 will abut against the first recess 11 due to the elastic force of the rotator 5, and the user's strength is not only extended. The connecting portion between the tube connecting portion 6 and the inhalation tool body 4 is also distributed to the first concave portion 11 .

Therefore, it is difficult to apply an excessive load to the connection portion between the extension tube connection portion 6 and the inhalation tool body 4 . As a result, it is possible to significantly suppress the occurrence of damage at the connection portion between the extension tube connection portion 6 and the inhaler main body 4 .

In addition, the suction tool 2 and the electric vacuum cleaner provided with the suction tool 2 of this embodiment also have the following effects.

First, as shown in FIG. 2 , the rotating body 5 is disposed so as not to protrude rearward from the rear portion of the inhaler main body 4 . Therefore, the appearance of the inhaler body 4 is improved.

In addition, the extension pipe connecting portion 6 is connected so as to be rotatable in the front-rear direction of the inhalation tool 2 , that is, in the direction from the arrow C toward the arrow D shown in FIG. 8 . In addition, the extension tube connecting portion 6 is connected so as to be rotatable in the left-right direction of the inhalation tool 2 , that is, in the direction from the arrow A toward the arrow B shown in FIG. 7 . That is, the extension pipe connecting portion 6 is connected to the inhaler main body 4 so as to be rotatable in either the front-rear direction or the left-right direction of the inhaler 2 . Therefore, the user can rotate the inhaler 2 in various directions to clean according to the situation. Thereby, the degree of freedom of operation of the electric vacuum cleaner is significantly improved compared with conventional electric vacuum cleaners.

In addition, the inhaler body 4 has a mound 7 extending from the substantially central portion (including the central portion) in the front-rear direction toward the front end, and the upper surface thereof is formed in a smooth curve. Thereby, even if the hill part 7 of the suction tool main body 4 collides with furniture etc., damage etc. of furniture can be suppressed. Also, the appearance is improved by the curved shape of the mound portion 7 . In addition, the smooth curved shape allows the inhaler body 4 to be easily inserted into a narrow place for cleaning.

Next, the internal configuration of the inhalation tool 2 will be described with reference to FIG. 9 . Fig. 9 is a diagram showing a side cross-section of the inhalation tool 2 of the present embodiment.

As shown in FIG. 9 , the extension tube connection portion 6 has a substantially hemispherical (including hemispherical) front end portion 6 a, and the front end portion 6 a is fitted into the rotating body 5 with a gap. Therefore, the extension tube connecting portion 6 becomes rotatable in the front-rear direction of the inhalation tool body 4 relative to the rotating body 5 .

Also, the rotating body 5 has, for example, a front end portion on the front side. Concavo-convex shaped rotating body fitting part 14 . On the other hand, the inhaler main body 4 of the inhaler 2 is provided with, for example, an inhaler fitting portion 15 in a concavo-convex shape at a portion connected to the front end portion of the rotating body 5 . In addition, the rotating body fitting part 14 and the inhaler fitting part 15 are fitted so as to be rotatable. Thereby, the rotating body 5 becomes rotatable relative to the inhaler main body 4 in the left-right direction of the inhaler main body 4 .

Moreover, the inhaler main body 4 has the inhalation port 9 formed in the bottom surface. In addition, the suction port 9, the flow path 16 in the inhaler body 4, the inside of the rotating body 5, and the inside of the extension tube connecting portion 6 communicate with each other through spaces formed in each. Therefore, the dust sucked from the ground through the suction port 9 passes through these spaces, passes through the space inside the extension pipe 1, and is collected in the dust collecting portion 23 of the handle portion 3 (see FIG. 18 ).

Furthermore, although not particularly mentioned in the above, it is also possible to arrange the detection dust and have Sensors such as light-emitting elements (light-emitting parts) and light-receiving elements (light-receiving parts) (so-called trash sensors). In this case, for example, a light emitting part composed of an LED (Light Emitting Diode) and that emits light when the sensor detects dust may be provided on the outer surface of the inhaler body 4 . Specifically, the light-emitting part is arranged on the outer surface of the inhaler body 4, such as the mound 7, and a power supply (such as a secondary Battery). Thereby, the user can easily confirm whether the dust has been inhaled into the inhaler body 4 by the light of the light emitting part. Furthermore, as long as the user can identify the position of the light, it will be It is not limited to the mound 7 of the inhalation tool body 4, and the installation position of the light emitting part may be arbitrary.

Furthermore, the sensor is not limited to a sensor that detects the passing of dust between the light-emitting element and the light-receiving element, for example, it may also be configured with a sensor that detects the collision of dust.

As described above, the inside of the inhalation tool 2 is constituted.

Next, the movement (movement) of the inhaler 2 accompanying the turning movement of the handle portion 3 will be described with reference to FIGS. 10 to 12 .

Fig. 10 is a side view of the electric vacuum cleaner. FIG. 11 is a perspective view of a state in which the handle 3 of the electric vacuum cleaner is rotated in the direction of arrow E. FIG. FIG. 12 is a perspective view of a state in which the handle 3 of the electric vacuum cleaner is rotated in the direction of arrow F. FIG.

Specifically, in the state where the user holds the handle part 3, when the handle part 3 is rotated in the direction of the arrow E in FIG. 11, the front side of the inhaler 2 also rotates in the direction of the arrow E (the right side when viewed from the user holding the handle 3).

Specifically, in the state where the user holds the handle part 3, when the handle part 3 is rotated in the direction of the arrow F in FIG. 12, the front side of the inhaler 2 also rotates in the direction of the arrow F (the left side when viewed from the user holding the handle 3).

That is, when the user rotates the handle portion 3 to the right (direction of arrow E), the inhaler 2 also rotates to the right (direction of arrow E). Moreover, when the handle part 3 is rotated to the left (direction of arrow F), the inhaler 2 is also rotated to the left (direction of arrow F). Therefore, the user can rotate the inhalation tool 2 in a desired direction (the same direction as the handle part 3 ) simply by rotating the handle part 3 in the right and left direction.

Hereinafter, the operation of the inhaler 2 when the user grips the handle 3 and turns it in the direction of the arrow F in FIG. 10 will be described in detail with reference to FIGS. 13 to 15 .

12 to 15 are perspective views showing the operation of the inhaler 2 when the handle 3 and the inhaler 2 are rotated toward the arrow G side (the left side as viewed from the user holding the handle 3 ).

First, when the user rotates the handle 3 to the left (direction of arrow F in FIG. 10 ), as shown in FIG. 13 , the extension tube connecting portion 6 is similarly rotated to the arrow G side. At this time, as shown in FIG. 14 , the rotating body 5 rotates in the direction of the arrow H along with the rotation of the extension tube connection portion 6 . In addition, the extension pipe connection portion 6 is swung forward (in the direction of the arrow I) so as to be in contact with the end portion 8a of the rotating body opening portion 8 . Afterwards, when the extension tube connection part 6 is further rotated, as shown in FIG. 15 , the inhalation tool body 4 and the extension tube connection part 6 become approximately perpendicular (including vertical) to each other. That is, the inhalation tool body 4 and the extension tube connection portion 6 are in a substantially L-shape (including the L-shape).

As described above, when the inhalation tool 2 is rotated to the left as viewed from the user holding the handle 3 , the inhalation tool 2 is also rotated to the left.

On the other hand, when the handle 3 is rotated to the right as viewed from the user holding the handle 3, the inhalation tool 2 is similarly rotated to the right. that is, Since the turning of the handle 3 to the right is the same operation as that of turning the handle 3 to the left, description thereof will be omitted.

Next, the external configuration of the handle portion 3 will be described with reference to FIG. 16 .

FIG. 16 is a perspective view of the handle portion 3 . In addition, the handle part 3 is formed with ABS resin, PP (polypropylene) etc. as a whole as above-mentioned.

As shown in FIG. 16 , the handle portion 3 includes an extension pipe connection portion 42 attached to the front end. The extension pipe connecting portion 42 is formed of, for example, an aluminum alloy or the like, and is connected to the extension pipe 1 .

The user usually connects the extension tube 1 to the extension tube connection part 42 to perform cleaning. However, the electric vacuum cleaner of this embodiment can clean only with the handle part 3, even if nothing is connected to the extension pipe connection part 42. As shown in FIG.
