Description

[Detailed description of the invention] Industrial applications The present invention is a dust collector that can be attached and detached from the upper opening of the dust collection chamber.

This reminds me of a vacuum cleaner with a lid.

As shown in the structure of the conventional example and its problems, there is a dust collection chamber 3 with an upward opening in which a dust collection bag 2 is installed in the front part of the lower body 1, and a dust cover that can be opened and closed at the opening of the dust collection chamber 3. 4, and a buckle 6 for locking the M4 in the closed state.

In addition, the lower body 1 and the dust lid 4 each have a handle, 7
It is possible to carry it by forming a
By doing so, it forms a handle that serves as the main body of the vacuum cleaner.

In the above configuration, when storing the dust M4 in the lower part 1 of the main body, misalignment often occurs in the left-right direction or front direction, making installation difficult, and air leakage occurs at the joint between the dust cover 4 and the lower part 1 of the main body. There was a problem that performance deteriorated.

Furthermore, when carrying a wooden vacuum cleaner, if a load is applied to the handle 7 on the dust lid 4 side, the handle 7 may be misaligned, resulting in decreased performance or, in some cases, problems such as hands being caught.

In addition, in order to solve the above problem, a large number of hoops are inserted into the inner surface of the dust collection chamber to regulate the position, but there are many fitting parts, making it difficult to attach and detach the dust cover. Ta.

OBJECTS OF THE INVENTION The present invention solves the problems of the conventional vacuum cleaner, and provides a vacuum cleaner with improved handling and performance of the dust cover.

Structure of the Invention The vacuum cleaner of the present invention includes a substantially cylindrical button on the inner surface of the front part of the dust l that is biased downwardly by a spring and is slidable up and down, and a substantially cylindrical button that accommodates and holds the button and the spring. By arranging a cylindrical guide, facing the button, and arranging a protruding body inscribed in the substantially cylindrical guide under the main body, the position of the dust lid is regulated, and the handling of the dust lid is improved.
and improved performance.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 8, 2o is the lower part of the main body, which has an upwardly-opening dust collection chamber 21 on the front side and an electric blower chamber 24 containing an electric blower 23 on the rear side, which is partitioned by a partition wall 22.

A front cover 25 is disposed at the front of the dust collection chamber 21 and fixed to the lower part 20 of the main body, and has a suction port 27 to which a hose 26 is connected.

A dust collection bag 28 is attached to the dust collection chamber 21, and a removable dust bag M29 is attached to the upper opening thereof, and is locked with a buckle 30.

A dust indicator 31 for detecting the amount of collected dust is arranged at the rear of the dust lid 29, and a handle 32 for carrying the dust lid 29 is formed at the front, which fits into a handle 33 formed at the front of the lower body 20. By fitting the dust cover 29 to the lower part 20 of the main body, a handle is formed as the main body of the vacuum cleaner.

An upper main body 34 is attached to the rear upper part of the lower main body 20 to house a stain moving air blower 24 and a cord winding device (not shown). 136 is a bumper, which includes the lower body 20, the upper body 34, and the dust cover 2.
It is located between 9 rooms.

36.37 is a tanano nozzle placed on the upper part of the lower body 34,
The gap nozzle is further covered with a cuff nozzle 38 that can be opened and closed, and the upper surface is configured to be a clean surface without any irregularities.

Reference numerals 39 and 40 are front wheels and rear wheels for movement disposed at the lower part of the lower body 20.

41 is located at the upper front part of the dust collection chamber 21, and the dust cover 29
It is a vertically slidable button arranged on the inner surface of the button, and is biased downward by a coil spring 42.

43 is a substantially cylindrical guide that holds the button 41 and the coil spring 42.

Reference numeral 44 denotes a protruding body formed of cross-shaped ribs disposed inside the dust collection chamber 21 of the lower body 20, and is located at a position corresponding to the button 41 and guide 43 disposed on the inner surface of the dust lid 29. They are designed to fit together.

41a is a protrusion formed on the circumferential surface of the button 41;
The button 41 is fitted and slid into a square hole 43a provided in the guide 43 by the force of the coil spring 42.
This is to prevent it from flying away.

Next, to explain the operational aspect, normally, as shown in FIG.
4 pushes up the button 41, the protruding body 44 is inscribed in the guide, and each cross-shaped surface is fitted into the guide 43 with some clearance.

When the buckle 3o is unlatched to discard the dust collection bag 28, the front part of the dust cover 29 is lifted up by the action of the coil spring 42 and the button 41, as shown in FIG. 5, and the handle 32 can be easily held. Remove the dust collection bag 28, insert a new dust collection bag, and attach the dust M29 again as shown in Fig. 4.

When attaching the dust cover 29, hold the handle 33 and set it, but make sure that the button 41 is in contact with the protrusion 44 so that your hand does not get caught between the handle 32 and the handle 33 of the lower body 20. Next, when the upper surface of the dust cover M29 is pushed, it is locked and fixed by the buckle 30, and the protrusion 44 enters into the guide 43, preventing the dust cover 29 from shifting.

Effects of the Invention As described above, in the measures of the present invention, the dust lock of the buckle can be removed from the outside fTt. The usability of the dust lid is improved by forming a protruding body that abuts on and fits inside the guide, and the button serves as a guide when installing the dust lid,
There is no need to get your hands caught between the handles, which improves safety.

Furthermore, the fitting between the guide and the protruding body prevents air leakage caused by misalignment when attaching the dust cover or misalignment of the handle when carrying the vacuum cleaner, and eliminates performance deterioration. This provides a highly efficient vacuum cleaner.

In addition, the button is located on the dust lid side, and if the button is damaged and comes off, there is a risk of danger when the dust lid is opened. Since there is no possibility of being hit, safety is guaranteed.
