Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a handy type vacuum cleaner, and particularly to a gripping structure for a case body constituting a vacuum cleaner body.

(Prior Art) Conventionally, in this type of handy-type vacuum cleaner, for example, a suction port is opened on the entire surface side, an electric blower is built in, and a dust collection part that communicates with the suction port and the electric blower is installed inside. A handle extending in the front-rear direction for gripping the main body case is integrally and fixedly provided on the rear side of the upper surface of the main body case.

(Problems to be solved by the invention) In the above conventional structure of the handy type vacuum cleaner,
Since the handle is integrally and fixedly provided to the main body case, if this handle is tilted forward and upward with respect to the longitudinal axis of the main body case, it will be lower than the gripping position of the handle. When cleaning from below, the handle is almost horizontal, making it easy to hold; however, when cleaning from approximately the same height as the gripping position, or slightly above, the handle must be held at an angle, making your wrists tiring and making it difficult to hold for long periods of time. There was a problem that it was difficult to clean.

In addition, if the handle is tilted downward toward the front with respect to the axis of the main body case, it will be easier to clean the area slightly above the handle position, but It becomes difficult to clean the area below the grip position of the handle, including cleaning by connecting the extension pipe or the suction port in the axial direction of the main body case.

Furthermore, when cleaning a fairly high place such as a lintel, it is easier to hold the handle with it tilted downward toward the rear, so it is easier to hold the handle tilted downward toward the front with respect to the axis of the main body case. The bent handle makes cleaning difficult.

Therefore, some vacuum cleaners have a handle that is parallel to the axis of the main body case, but this results in a handle that is half-finished, making it difficult to clean both below and above the grip position of the handle. be.

The present invention provides a first case body provided with a suction port,
By rotatably connecting the second case body provided with the handle, it can be used at any height, including when connecting an extension pipe or suction port body to the suction port. To provide a handy type electric vacuum cleaner whose handle can be held in a state with the least strain even when cleaning.

Furthermore, as described above, the present invention includes a first case body and a second case body rotatably connected to the first case body, and includes a battery and an electric blower driven by the battery. To provide a handy type vacuum cleaner in which the heavy battery is disposed in a second case body provided with a handle, thereby reducing the burden when holding the case body. It is something to do.

(Means for Solving the Problems) The handy type vacuum cleaner of the present invention includes a first case body having a suction port opened on the outside surface and a dust collection portion communicating with the suction port formed therein; a second case body rotatably connected to the first case body and provided with a handle; and the second case body is held in a predetermined position within a predetermined rotation angle range with respect to the first case body. An electric blower driven by a battery is disposed inside the first case body, and the battery is disposed inside the second case body.

(Function) The handy type vacuum cleaner of the present invention is rotatably connected to a first case body having a suction port and a dust collection portion communicating with the suction port. By rotating the second case body having the handle within a predetermined rotation angle range, the second case body is held at a desired rotation angle with respect to the first case body by the holding means. . For example, even when cleaning an area slightly above the gripping position of the handle, or cleaning an area below the gripping position of the handle, including when an extension pipe or a suction port body is connected to the suction port. In the first case, the handle can be held in a substantially horizontal position, and when cleaning a fairly high position such as a lintel, the handle can be held in a downwardly tilted position. The positional relationship between the body and the second case body having a handle for gripping the case body can be changed.

Further, by disposing an electric blower driven by a battery inside the first case body and a battery inside the second case body, the burden when holding the case body can be reduced.

As shown in Fig. 1, the suction port 2 of the dust collection case 3
When cleaning the floor 39 etc. by sequentially connecting the extension pipe 37 and the suction port body 38 to the
is connected in the same direction as the longitudinal axis of the first case body 1, so that the first case body 1 is inclined downwardly toward the front. Then, the engagement protrusion 30 of the convex part 29 of the second case body 4 is engaged with the engagement groove 6 of the concave part 5 of the main case 2 of the holding means, and the second case body 4 is connected to the main case 2. It is held at a predetermined rotation angle position. Therefore, if the second case body 4 is rotated downward relative to the first case body 1, the handle 33 becomes approximately horizontal, and even if you hold the handle 33 for a long time while cleaning, it will not strain your wrist. There is no need to bend over, reducing fatigue.

As shown in FIG. 2, when cleaning a vertical surface such as a wall surface 40 or an inclined surface 40a, when the suction port 20 of the dust collection case 3 is opposed to the wall surface 40, the first case body 1 is approximately becomes horizontal. Therefore, if the second case body 4 is rotated upward with respect to the first case body 1, the second case body 4 is held at this rotation angle position by the holding means, and the handle 3
3 is in a substantially horizontal position, and the holding means allows for easy cleaning without putting too much strain on the wrist.

In addition, as shown in FIG. 3, when cleaning a corner 41 between a floor surface 39 and a wall surface 40, for example, when the suction port 20 is opposed to the corner 41, the first case body 1 is in a state where it is tilted downward toward the front. Therefore, if the second case body 4 is rotated downward with respect to the first case body 1,
The second case body 4 is held in this rotational angular position by the holding means, and the handle 33 becomes approximately horizontal.

Furthermore, as shown in FIG. 5, when cleaning a fairly high place such as the lintel 42, it is easier to hold the handle 33 by tilting it downward toward the rear. 4 is rotated downward with respect to the first case body 1, the second case body 4 is held in this rotational angular position by the holding means, and the first case body 1 is held in a substantially horizontal position. Since the suction port 20 can be placed close to the lintel 42, etc., cleaning efficiency is increased.

In this way, by rotating the second case body 4 with respect to the first case body 1, the second case body 4 is held at this rotational angular position by the holding means. Even when cleaning a place, the handle 33 can be held with the least strain.

Further, although the battery 35 has a considerable weight, since the battery 35 is disposed below the handle 33 within the second case body 4, the battery 35 has a considerable weight.
5 can minimize the burden when gripping due to the weight of the first case body 1, and the suction port 20 of the first case body 1 can be
When cleaning by moving the
Since the weight is concentrated near the handle 33, which serves as the pivot point, it does not put a strain on the wrist and is easy to clean.Furthermore, since the first case body 1 is lighter, the grip of the second case body 4 stabilizes the holding of the first case body 1.

(Effects of the Invention) According to the present invention, the second case body having the handle is rotatably connected to the first case body having the suction port, and the second case body is connected to the first case body with respect to the first case body. Since a holding means is provided to hold the handle in a predetermined position within a predetermined rotation angle range, when cleaning by gripping the handle, even when cleaning above the gripping position of the handle, or by extending it to the suction port. Even when cleaning below the gripping position, including when cleaning by connecting a pipe or suction port body, the handle can be kept in a substantially horizontal position, and when cleaning a fairly high place such as a lintel. , the handle can be tilted downward toward the rear, and the suction port can be brought close to the lintel, and each of these positions can be held by a holding means, so that it can be cleaned at any height. Even when cleaning, the handle can be held with the least amount of strain, allowing efficient cleaning.

Furthermore, in a vacuum cleaner that has a battery and an electric blower driven by the battery, the battery, which has a considerable weight, is attached to a second case body that is rotatably connected to the first case body and provided with a handle. With this arrangement, the burden on the handle due to the weight of the battery can be reduced.
