Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a no-day type vacuum cleaner equipped with a one-touch mechanism for a dust collection lid.

BACKGROUND OF THE INVENTION Handheld vacuum cleaners have become popular in recent years because they are convenient to use, but it is desired to be able to easily dispose of dust in a dust collection box.

By the way, a conventional hand-held vacuum cleaner is constructed as shown in FIG. That is, it consists of a main body 13 that incorporates a suction mechanism such as a motor 14, and a dust collection box 19 that is equipped with a filter 17 and is joined to the end of the main body 13. The part 16 is configured such that the receiver provided below the main body joint part engages with the part 16, and the upper part of the joint part of the dust collection box 19 is connected by a locking mechanism provided at the upper part of the main body joint part. has been done.

Specifically, the above-mentioned locking mechanism is constructed as follows.In other words, a protrusion 21 is provided at the front end of the handle 24 at the upper part of the main body joint, and protrudes from the surface of the joint. Dust collection box 19
An engaging recess 2 into which the protrusion 21 fits is provided at the upper part of the joint.
o is formed, and the main body 13 and the dust collection box 19 are coupled by locking by fitting the protrusion 21 and the engagement recess 20 together. A buckle 23 for unlocking is attached to the front of the handle 24. In the figure, 18 is a connection port for a hose provided in the dust collection box 19, 22 is a switch, and 26 is a circuit component. Note that the reference numeral 20 is an engaging concave portion, which also serves as a grip portion of the dust collection box 19 when performing dust disposal.

Problems to be Solved by the Invention However, in the conventional vacuum cleaner described above, the main body 13 and the dust collection box 19 are separated, and when handling dust, it is necessary to use both hands, making it difficult to use. It was bad.

The present invention solves these conventional problems, and has a simple configuration that automatically opens the dust collection lid with one touch, thereby making it possible to easily dispose of dust with one hand. It provides an opportunity for

Means for Solving the Problems In order to solve the above problems, the present invention pivots the dust collection lid to the main body by a shaft fixed to the upper part of the joint on the main body side, and connects the lower engaging part to the end of the main body. It can be freely engaged with the engaging part on the lower part of the part. The shaft of the dust collecting lid is inserted into a long hole provided in the main body, and is movable in a direction away from the end of the main body.

Furthermore, a spring with a shaft that biases the shaft toward the main body and a lid biasing spring that biases the dust collection lid upward to rotate are provided, and the spring is pressed at the upper part of the main body joint and at the front position of the handle. A buckle is provided for operating the shaft in a direction away from the main body.

Effect With the above structure, when opening the dust collection lid, pressing the buckle pushes the shaft forward, and at the same time the dust collection lid is also pushed forward, disengaging the main body from the lid, and pressing the lid. The spring automatically opens the lid.

Conversely, when closing the dust collection lid, the engaging portion at the tip is engaged with the main body by pressing the front of the lid, and the shaft is pushed toward the main body by the shaft biasing spring to maintain the engaged state.

Embodiment A vacuum cleaner according to an embodiment of the present invention has a structure as shown in FIGS. 1 to 3. In other words, there is a dust collection box 3 in the front.
The main body 1 has a built-in suction mechanism such as a motor 2 at the rear.
and a dust collection lid 5 that opens and closes the dust collection box 3, which is opened at the front and upper side. Totomoto,
The lower engaging portion 6' is configured to be able to freely engage with the engaging portion 1' at the lower end of the main body 1. Furthermore, the shaft 6 of the dust collecting lid 5
a spring 8 with a shaft, which is inserted into a long hole 7 provided in the main body 1 and is movably provided in a direction away from an end of the main body 1, and biases the shaft 6 toward the main body; A lid spring 9 is provided which urges the dust collecting lid 6 to rotate upward. In addition, at the upper part of the main body joint and at the front position of the handle 12, the part that comes into contact with the shaft 6 has an inclined surface, and a buckle that operates the shaft 6 in the direction away from the main body 1 when pressed. 1° is set. In addition, in the figure, 4 indicates a suction port, and 11 indicates a switch.

In the opening/closing operation of the dust collection lid 5 in the above configuration, by pushing the buckle 1o downward, the shaft 6 is pushed forward by the inclined surface of the buckle 1o, and at the same time, the dust collection lid 5 is also pushed forward. As a result, the engagement between the main body locking pawl 1' and the dust collection lid locking pawl 6' is disengaged, and the dust collection lid 5 is automatically opened upward by the spring force of the lid attachment spring 9.

Next, when closing the dust collection lid 5, by pushing the dust collection lid 6 downward, the main body locking claw 1' and the dust collection lid locking claw 5' are engaged, and the shaft biasing spring 8 The shaft 6 is pushed toward the main body and the engagement is maintained.

Effects of the Invention As is clear from the description of the embodiments above, the vacuum cleaner of the present invention has a simple structure consisting of three points: the shaft, the elongated hole, and the engaging part, so that the dust collection lid can be opened automatically with one hand or with a single touch. It can be opened and dust can be easily cleaned with one hand. Furthermore, when closing the dust collection lid, the lid can be easily closed by pressing the lid lightly, thereby realizing an easy-to-use, hand-held vacuum cleaner that can be used to dispose of dust with one touch.
