Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small electric device having a built-in rechargeable battery, and takes measures to recover the rechargeable battery.

[0002]

2. Description of the Related Art In recent years, rechargeable batteries such as Ni-Cd batteries have become mainstream in rechargeable electric razors and various other small electric devices because they can be repeatedly used as the power source compared to dry batteries. Since toxic substances such as cadmium are used, it is not preferable to dispose of the whole equipment everywhere anywhere in terms of pollution prevention, and it should be noted from the viewpoint of effective utilization of rare metals. Therefore, at the time of disposal, it is necessary to remove the rechargeable battery from the device and collect it.

[0003]

However, unlike the dry battery, the rechargeable battery cannot be easily taken out from the device. If the contact terminal plate such as a coil spring or leaf spring is used as the rechargeable battery is stored in the device,
The contact resistance increases with the lapse of time and the characteristic of the rechargeable battery that a large current can be taken out cannot be exhibited. Therefore, the rechargeable battery must be firmly connected and fixed to the circuit in the device by soldering or the like. In such a mounted state of the rechargeable battery, the rechargeable battery cannot be taken out from the device unless the soldered portion is removed or the lead wire is cut with a blade or the like.

Further, since it is difficult to know from which part of the device the rechargeable battery is housed, it is necessary to break the entire device when taking it out, but such destruction is not an easy task. In particular, when the rechargeable battery is taken out by an actual general user, not by a service person of the equipment, it does not have a special removing jig, which is extremely difficult. Further, if the rechargeable battery is accidentally taken out while the device is connected to a commercial AC power source and being charged, there is a risk of electric shock.

The present invention solves the above-mentioned conventional problems,
The purpose of the present invention is to facilitate the taking out of the rechargeable battery and thus contribute to the facilitation of the recovery work. It is another object of the present invention to prevent electric shock when taking out the rechargeable battery and enhance the safety of taking out the rechargeable battery.

[0006]

In order to achieve the above object, in the rechargeable small electric device of the present invention, the main body case containing the rechargeable battery has a removable connection portion for connection with a commercial AC power supply at the time of charging. It is characterized by being attached.

[0007]

When the rechargeable battery is taken out of the main body case for disposal, it can be easily taken out by removing the connecting portion from the main body case. When the rechargeable battery is taken out, the connection part is removed in this way, so the connection with the commercial AC power supply can be cut off, and an electric shock accident can be prevented.

(First Embodiment) A first embodiment in which the present invention is applied to a rechargeable electric shaver will be described with reference to FIGS. 1 to 3. In FIGS. 1 and 2, a rectangular tubular body case 1 for an electric razor is provided with a razor blade unit 2 at its upper portion and a charging plug 3 at its bottom portion which can be operated to move in and out. A razor blade driving motor M (see FIG. 3), a wiring board 4, and the like are housed and arranged inside the main body case 1. On one side surface 1a of the main body case 1, there is provided a plug blade exit / exit 6 through which the plug blade 5 of the charging plug 3 exits / retracts, and a case opening 7 is arranged in the vicinity of the plug blade exit / entrance 6 to form the case. One side face 1a is opened over three faces, namely, a front face 1b and a rear face 1c intersecting with the one side face 1a.

On the wiring board 4, a pattern corresponding to the circuit shown in FIG. 3 is formed, and a rechargeable battery 8 such as a Ni-Cd battery, a transformer 9 and a switch 11 are mounted. As shown in FIG. 2, the rechargeable battery 8 has a negative / anode terminal 12.1.
3 is connected and fixed to the lead pieces 14 and 15 on the substrate 4 by soldering or the like. At least the rechargeable battery 8 on the wiring board 4 is arranged so as to face the case opening 7. The rechargeable battery 8 is detachably attached to the wiring board 4. For example, at least the peripheral portion 4a of the terminal connecting portion of the wiring board 4 that is connected to the terminal of the rechargeable battery 8 is folded along the fold line 16 formed by a large number of small holes or grooves.

A battery lid 17 having a U-shaped cross section, which constitutes a part of the case of the main body case 1, is attached to the case opening 7 so as to be opened in the same direction A as the protruding direction of the plug blade 5. The battery lid 17 has a finger slip prevention portion 10 and a predetermined number of elastically deformable engagement claws 18,
Utilizing this elasticity, the claw 18 can be freely engaged with and disengaged from the edge of the case opening 7. The battery lid 17 maintains the closed state of the case opening 7 by engaging the engaging claw 18 with the edge of the case opening 7, and the battery lid 17 holds the finger slip prevention portion 10 by hand. When pulled in the direction A, the engagement of the engagement claw 18 with the edge of the case opening 7 is released, and the engagement claw 18 is removed from the main body case 1. The battery lid 17 is provided with a window 19 through which the presence of the rechargeable battery 8 can be visually recognized even from the outside.

Now, to charge this device, as shown in FIG. 1, the plug blade 5 is operated to project so as to be inserted into the outlet 20 attached to the wall or the outlet at one end of the power cord. In such a charging state, the outlet 20 is present close to the opening direction A of the battery lid 17, so that the battery lid 17 cannot be opened because the outlet 20 is an obstacle. Therefore, during this charging, the rechargeable battery 8 is not accidentally taken out, which is safe. However, when not charging, the battery lid 17
Since the battery can be removed, the rechargeable battery 12 can be taken out from the wiring board 4 by breaking it along the break line 16. It should be noted that the charging plug 3 may be of a type that can be freely retracted and retracted by a well-known rotating operation, in addition to the form of being freely retractable and retractable by the above-described sliding operation.

(Second Embodiment) FIGS. 4 and 5 show a second embodiment of the present invention. In this embodiment, a case opening 7 is provided on the bottom side of the main body case 1, and the wiring board 4 in the main body case 1 is filled in with the folding points 4a and 4a projecting so as to be folded toward the case opening 7. The battery 8 is mounted and the socket pin 21 mounted on the board 4 is projected toward the case opening 7. A battery lid 17 is removably attached to the case opening 7. In this case, the battery lid 17 has the plug 23 of the power cord 22 inserted / removed so as to be a connection portion for connection with a commercial AC power source during charging. An engaging claw 18 which has a charging plug receiving port 24 and a window 19 for visualizing a rechargeable battery, and is elastically deformable
By having the claw 18 engageably and disengageably with the rim of the case opening 7, the closed state of the case opening 7 is maintained. When the battery lid 17 is closed, the socket pin 2
1 rushes into the charging plug receptacle 24.

In such a structure, when the plug 23 of the power cord 22 is inserted into the plug receiving opening 24 during charging, the plug 23 becomes an obstacle and urges the removal prevention of the battery lid 17, therefore, In this case, the rechargeable battery 8 cannot be taken out by mistake, and there is no risk of electric shock.
Since the battery lid 17 can be removed while the plug 23 is being pulled out from the charging plug receiving port 24, the rechargeable battery 8 can be taken out from the wiring board 4 by this removal. At this time, since the battery cover 17 is removed, the connection with the AC commercial power source can be cut off, and an electric shock accident can be prevented.

(Third Embodiment) FIG. 6 shows a third embodiment of the present invention. In this embodiment and the second embodiment, the case opening 7 is provided on the bottom side of the main body case 1, and the rechargeable battery 8 is mounted on the wiring board 4 in the main body case 1 along the fold lines 16 so that the rechargeable battery 8 can be folded. Is exposed to the case opening 7, and a battery lid 17 constituting a connecting portion with a commercial AC power source is detachably attached to the case opening 7 at the time of charging,
Both of them are common to each other, but they are different in that the former is configured as a connection portion in which the charging plug 3 is provided on the battery lid 17 so as to be freely retractable. In the case of such a configuration, at the time of charging, the charging plug 3 is inserted into the outlet 20 in the same manner as the charging mode in the case of the first embodiment, and therefore the battery lid 17 cannot be removed at this time, and the rechargeable battery 8 is It cannot be accidentally taken out. When the battery is not charged, the battery lid 17 can be removed so that the rechargeable battery 17 can be taken out, and the connection with the commercial AC power supply can be cut off at the time of taking out the battery as in the first and second embodiments. It is the same.

(Fourth Embodiment) FIG. 7 shows a fourth embodiment of the present invention. This embodiment is basically the same as that of the second embodiment, but in the case of the second embodiment, the socket pin 21 is provided on the main body case 1 side,
In this embodiment, the socket pin 21 is a charging plug receptacle 2 of the battery lid 17 which constitutes a connection portion with a commercial AC power source during charging.
The only difference is that the one end 21a of the socket pin 21 is inserted into and connected to the pin hole 31 on the substrate 4 when the battery lid 17 is attached to the case opening 7 provided on the No. 4 side.

(Fifth Embodiment) FIGS. 8 to 10 show a fifth embodiment of the present invention. In this embodiment, a case opening 7 is provided on one side surface of the main body case 1, and a charging plug receiving port 24 is provided on the bottom side surface thereof.
The battery lid 17 is removably attached to the. When the plug 23 on the power cord side is inserted into the charging plug receptacle 24 between the battery lid 17 and the charging plug receptacle 24, the battery lid 17 is locked and cannot be opened. A lid lock means that enables opening is provided. As the lid locking means, the main body case 1
The first lock piece 26 having an L-shaped cross section is vertically movably installed in the guide groove 25 formed between the case opening 7 and the charging plug receptacle 24, and the one end 2 of the first lock piece 26 is
6a is projected into the charging plug receptacle 24, and the other end 26b
As shown in FIG. 9, only when the first locking piece 26 is raised, the first locking piece 26 projects into the case opening 7 and engages with the notch 27 on the battery lid 17 side.

In addition to the lid locking means, the battery lid 1
A charging blocking means is provided to prevent the plug 23 from being inserted into the charging plug receptacle 24 when the plug 7 is opened. This charge blocking means is provided with a second lock piece 29 having an L-shaped cross section in a guide groove 28 formed between the case opening 7 of the main body case 1 and the charge plug receiving port 24 so as to be slidable in the horizontal direction.
It is assumed that the tip end 29a of the second lock piece 29 slides vertically to open and close the upper end opening of the guide groove 25 that faces the case opening 7.

Thus, as shown in FIG. 8, when the plug 23 on the power cord side is not inserted into the charging plug receptacle 24, that is, when the charging is not performed, the first lock piece 2
6 descends in the guide groove 25 due to its own weight or downward spring biasing force, and the second lock piece 29
Is pushed against the spring 30 by the battery lid 17. Therefore, at this time, the battery lid 17 can be taken out from the case opening 7. However, as shown in FIG. 9, when the plug 23 on the power cord side is inserted into the charging plug receptacle 24, the first lock piece 26 is raised by the plug 23 and its one end 26b is engaged with the cutout portion 27 of the battery lid 17. Therefore, the battery lid 17 cannot be removed.

To take out the rechargeable battery 8, the battery lid 17 is removed under the condition shown in FIG. 8. As shown in FIG. 10, the second lock piece 29 is projected by the spring 30 to close the guide groove 25 and close the first groove. A state in which the rise of the lock piece 26 is regulated is obtained. Therefore, at this time, even if an attempt is made to insert the plug 23 on the power cord side into the charging plug receptacle 24, the one end 26a of the first lock piece 26 interferes with the insertion, that is, the charging cannot be performed. This is safe because it is possible to prevent an erroneous operation of charging the battery 8 when taking it out.

(Sixth Embodiment) FIGS. 11 to 13 show a sixth embodiment of the present invention. This embodiment shows a modification of the fifth embodiment, and is similar to the fifth embodiment in that the first lock piece 26 is incorporated between the battery lid 17 of the main body case 1 and the charging plug receptacle 24. However, the specific mechanism of the charge blocking means by the second lock piece 29 is different from that. That is, the second lock piece 29 of this embodiment is formed in a U-shaped cross section so that it can be slid horizontally in the guide groove 28 formed between the case opening 7 of the main body case 1 and the charging plug receptacle 24. The lock piece 29 is assembled via a spring 30, and one end 29a and the other end 29b of the lock piece 29 are slidably movable to and from the case opening 7 and the charging plug receptacle 24, respectively. Thus, as shown in FIG. 11, when the plug 23 on the power cord side is not inserted into the charging plug receptacle 24, that is, when the charging is not performed, the first lock piece 26 is descending in the guide groove 25. The second lock piece 29 is pushed by the battery lid 17 against the spring 30. Therefore, at this time, the battery lid 17 can be taken out from the case opening 7.

However, as shown in FIG. 12, when the plug 23 on the side of the power cord is inserted into the charging plug receptacle 24, the first lock piece 26 is raised by the plug 23 and its one end 2
Since 6b is engaged with the cutout portion 27 of the battery lid 17, the battery lid 17 cannot be removed. To take out the rechargeable battery 8, when the battery lid 17 is removed under the state shown in FIG. 11, the second lock piece 29 causes the spring 30 to move as shown in FIG.
And the charging plug receptacle 24 is closed at its one end 29b. Therefore, at this time, the plug 23 on the power cord side cannot be inserted into the charging plug receptacle 24, and charging is impossible.

(Seventh Embodiment) FIG. 14 shows a seventh embodiment of the present invention. In this embodiment, a case opening 7 is provided on one side surface of the main body case 1, and a charging plug receptacle 24 is provided on the bottom side surface thereof. It is assumed that the case opening 7 is opened by sliding on the outer surface of 1 in the orthogonal direction, and at the same time, the charging plug receptacle 24 is closed by the lid 17. The battery lid 17 cannot be returned in the opposite direction once it is moved in the B direction as described above. Therefore, the battery lid 17
Is moved to the side of the charging plug receptacle 24, the case opening 7 is opened, and the charging plug receptacle 24 is closed, the rechargeable battery 8 can be taken out. There is no. Of course, in this case
Instead of the charging plug receptacle 24, the plug blade outlet / retract opening 6 shown in the first embodiment may be closed.

(Other Embodiments) In each of the above-described embodiments, as means for removing the rechargeable battery 8 from the wiring board 4, in addition to the above-described embodiment, for example, the terminals of the rechargeable battery 8 and the wiring board 4 can be removed. The lead wire or the lead piece for connecting to the pattern is weakly structured by perforation or the like, and the rechargeable battery 8
May be pulled from the wiring board 4 so that the weak wire structure portion of the lead wire or the lead piece can be torn off. Further, according to the present invention, the rechargeable battery 8 is provided on the wiring board 4.
The same applies not only to the case where two or more pieces are mounted. Furthermore, the rechargeable battery 8 is not limited to being directly mounted on the wiring board 4, but can be similarly applied to a normal accommodating form such as being sandwiched by holding ribs protruding from the inner wall of the main body case 1.

[0024]

In the rechargeable small-sized electric device of the present invention, the connecting portion connected to the commercial AC power supply can be detached from the main body case at the time of charging, so that it is unreasonable to break the main body case unnecessarily. The rechargeable battery can be easily taken out from the main body case by removing the connecting portion without doing the above. In addition, since the connection portion is removed in such a manner when the rechargeable battery is taken out, the connection with the commercial AC power supply can be cut off, and an electric shock accident can be prevented, which is safe.
