Description

  The present invention provides a design of a rechargeable dust collector, and particularly refers to a rechargeable dust collector that extends the usage time of the dust collector by operating voltage distribution technology and does not break the rechargeable battery.

  Many of the power supply parts of rechargeable dust collectors currently on the market are designed in combination with an electric motor (motor) using a set of batteries. When the switch is turned on, the batteries output electric energy in series (for example, in a certain dust collector) Four 1.2V, 1300mA batteries are attached, and when it is turned on, it outputs 4.8V power) to drive the motor, and the purpose of dust absorption is achieved through the discharge operation of this battery set. FIG. 1 shows a well-known electronic circuit of a rechargeable dust collector. The power supply circuit includes a set of battery sets used to supply power to the motor, and charging and discharging of the battery set (to the motor). A changeover switch is included to complete the changeover between The usage time of the dust collector is determined by dividing the amount of electricity in the battery by the electric current of the motor, but in this way, this type of rechargeable dust collector can only use one set of batteries, so the usage time is relatively short and constantly charged. Otherwise, it cannot be used continuously. Compared to this type of rechargeable dust collector power supply system, only a few manufacturers in the market can use the dust collector through a reduction in the power output to the motor (using resistors) under the condition of using a set of batteries. However, such an improvement method cannot solve the problem that the battery life is substantially short.

  In addition, some manufacturers have adopted power supply with one or more batteries to extend the usage time of the dust absorber. FIG. 2 shows a conventional mother-child type dust absorber, which mainly employs two sets of batteries 6 and 5 and is attached to the main body and the separate child machine, respectively, and the mother and child machines are used in an integrated manner. In this case, it simultaneously feeds power from the two sets of batteries to drive the motor, and when the slave unit is detached from the mother unit and used alone, completes power feeding work from the battery set 5 of the slave unit. In this way, when the slave unit is used for a certain period of time and then combined with the mother unit again, the amount of electricity of the mother unit battery set 6 and that of the slave unit battery set 5 are different, leading to a change in output voltage. Then, the battery set with a high amount of electricity is charged to the battery set with a low amount of electricity. Therefore, not only the purpose of extending the use time of the dust absorber cannot be achieved, but also the two batteries are charged with each other and the battery set is broken. FIG. 3 shows a generally well-known dust absorber, and also uses two battery sets 7 and 8 to supply power. Although it is not a separate type of mother-child type dust absorber as shown in FIG. The amount of electricity of each battery set does not always match, which leads to charging from a battery set with a high amount of electricity to a battery set with a low amount of electricity, and the battery is broken.

  The present invention has been completed to solve the above-mentioned problems. The purpose of the present invention is to provide a silicon stack or a diode between at least two battery sets through operation of voltage distribution technology, and to supply power through at least two battery sets. Thus, it is possible to provide a rechargeable dust collector that extends the use time and charges and discharges each other due to the uneven electric quantity of the two batteries, thereby preventing the battery from being broken.

  The purpose of the present invention is to provide a rechargeable dust collector design, which mainly uses voltage distribution technology on a minimum of two sets of existing rechargeable dust collector batteries to increase the usage time of the rechargeable dust absorber. However, the operating time is extended under the condition that the motor is not changed and the output voltage is not changed, and the charging and discharging processes are controlled to avoid the damage of the battery.

In order to achieve the above-described object, the rechargeable dust collector of the present invention includes a dust collector body, a minimum of two sets of rechargeable batteries used for driving an electric motor in the dust absorber, and a power supply control unit.
Among them, the power supply control unit, the rechargeable battery set, and the electric motor are connected to each other to supply power to the electric motor from the battery set with a high voltage, and the set with a low electric quantity from the battery with a high electric quantity. It is used to prohibit charging the battery.

  Among them, the power supply control unit, the rechargeable battery set, and the electric motor are connected to each other when the positive electrode of the rechargeable battery set is connected to one end of the electric motor through the power supply control unit. This means that the negative electrode of the rechargeable battery set is connected to the other end of the electric motor.

  In order to achieve the above object, the rechargeable dust collector of the present invention further includes a charging unit and a changeover switch. The charging unit and the power supply control unit are connected to each other, and the rechargeable battery described above is connected to the power supply control unit. Completing charging to the set, one end of the changeover switch is connected to the negative electrode of the above-mentioned rechargeable battery, and the other end is connected to the above-mentioned charging unit or the above-mentioned electric motor to complete switching between charging and discharging of the rechargeable battery To do.

The aforementioned power supply control unit includes a silicon stack or a diode, and the silicon stack is a bridge type rectifier.
The effects of the present invention are as follows. In the situation where the number of battery sets is increased, the voltage distribution technology can be used in the dust collector power supply circuit to effectively extend the usage time of the dust collectors, and to perform overall management for charge / discharge of each battery set. Even if the amount of electricity stored in the battery set is different, it can be powered simultaneously when used together, or it can be powered from a battery set with a high voltage but without charging each other, extending the usage time of the dust collector, The battery will not be damaged.

Hereinafter, a power supply method according to an embodiment of the present invention will be described in detail with reference to the drawings. However, since the operation of the dust absorber itself is the same as that of the existing dust absorber, it will not be described in detail here.
The purpose of the present invention is as follows. Operate the voltage distribution technology in the dust absorber, and manage the charge / discharge of each battery group under the condition that the number of battery groups is increased, and (1) use a single power supply alone, (2) two sets (3) When the power storage amount of each power source is non-uniform but used together, the power sources can be supplied at the same time, but the purpose of not charging each other is achieved.

  FIG. 4 is a circuit diagram showing an electric circuit using a voltage distribution technique according to an embodiment of the present invention. As shown in the drawing, the positive electrodes of the two sets of rechargeable batteries BT1 and BT2 are connected to one end of the electric motor through the power supply control unit (including a silicon stack or a diode), and the rechargeable battery sets BT1 and BT2 The negative pole is connected to the other end of the motor. In addition, it includes a charging unit (charging circuit) and a changeover switch SW, and the charging unit is connected to the above-described power supply control unit, and charging to the above-described charging batteries BT1 and BT2 is completed through the power supply control unit. . One end of the changeover switch SW is connected to the negative electrode of the above-described charging battery set, and the other end is connected to the above-mentioned charging unit or electric motor M, thereby completing the switching between charging and discharging of the charging batteries BT1 and BT2. When the voltage of the rechargeable battery BT1 is higher than that of the other set of rechargeable batteries BT2, the voltage at the end of the silicon stack 2 is higher than the voltage at the 3 end, so that the diode at the 3 end exhibits a cut-off state and the voltage of the rechargeable battery BT1. Thus, no power is supplied to the rechargeable battery BT2. When the voltage of the rechargeable battery BT2 is higher than that of the rechargeable battery BT1, the voltage at the end of the silicon stack 2 is higher than the end, and the diode at the end is cut off and the rechargeable battery BT1 is not supplied with the voltage of the rechargeable battery BT2. Is done. When the voltage of the rechargeable battery BT1 is equal to the rechargeable battery BT2, the diode has a voltage drop of 0.7-1.1V, so that the function of supplying power simultaneously but not charging each other is achieved.

As can be seen from the above, when the dust suction device is started, the voltage distribution circuit achieves the purpose of supplying power on average by switching between the battery sets that are continuously in charge by the voltages of the two sets of batteries, and the same at the time of charging.
FIGS. 5 and 6 are schematic views showing a mother-child dust absorber according to an embodiment of the present invention. The mother-child dust absorber includes a mother machine body A and a separate child machine B, and connection terminals 9, 10. The sub-unit B and the main body A of the dust absorber are connected to a power source, and the two sets of rechargeable batteries 5 and 6 are attached to the separate sub-unit and the main unit main body, respectively, and are assembled so as to surround the outside of the electric motor. When the mother and child devices are combined and used, power is supplied from two sets of batteries at the same time. When the child device is separated and used alone, the rechargeable battery set 5 of the child device is operated independently of the motor. When the slave unit is used for a certain period of time and is used in combination with the mother unit again, a set of batteries with a higher voltage is used preferentially due to the action of the silicon stack, so the voltage drop Accordingly, two sets of batteries are constantly switched, and the purpose of extending the use time using the two sets of batteries is achieved.

  Further, as a feature of the mother-child dust absorber of the present embodiment, since two sets of rechargeable batteries 5, 6 are located in the child device B and the mother device A, when the child device B is taken out and used alone, the mother device A The rechargeable battery set 6 is still fully satisfied. When the handset B is returned to the main unit A, the design of the distribution circuit preferentially uses the rechargeable battery 6 of the main unit. The characteristics of 5 and 6 can be sufficiently exhibited.

  FIG. 7 shows a general-type dust absorber that is operated using two sets of batteries. The general-type dust collector is not divided, and two sets of batteries 7 and 8 are attached to the same body, and through the connection line 11. Connected to each other, the control circuit board (not shown in the drawings) controls the power supply from the first or second set of batteries to the motor. The dust absorber cannot guarantee that the electric quantities of the two rechargeable batteries 7 and 8 are consistent throughout the operation process. If the electric quantities are not equal, the electric power feeding control unit ( The purpose of supplying power from the high voltage pair in the two sets of batteries through the action of the silicon stack or the diode, or simultaneously supplying them, or charging each other, extending the usage time of the dust collector, and not destroying the batteries Achieved.

Furthermore, as a feature of the general dust absorber of this embodiment, since two sets of batteries are used, a power source in which one set of batteries is arranged in parallel may be adopted for the motor used, and the distribution technology is operated. If two sets of batteries are used, twice the usage time can be obtained.
The silicon stack mentioned above refers to a bridge type rectifier, and its purpose is as follows. It can be charged with two sets of batteries, but it does not charge any one set of batteries in the reverse direction, it can achieve the effect with a reverse peak of only 50V, so it can be completed even with a diode. Can do. The charging circuit described above has no special requirements and can be charged with a linear or switch transformer.

8 to 11 are schematic views showing a control PCB (printed circuit board) of a mother-child dust absorber and a general dust absorber according to an embodiment of the present invention, and a power supply control unit of the rechargeable dust absorber can be provided in the control PCB. .
In summary, the rechargeable dust collector of the present invention uses voltage distribution technology for the dust collector, increases the usage time of the dust collector with spare parts, and the DC dust collector supplies power from a set of series batteries. The purpose of increasing the usage time can be achieved by using two sets of series batteries. On such a basis, the rechargeable dust collector of the present invention is controlled by supplying two sets of batteries continuously with the power supply control unit as a controller and supplying power to the motor, and the principle is to operate the voltage drop. Two sets of batteries were fed to the motor on average. If it is used in a general dust collector, a relatively long operating time can be obtained by using a motor with a relatively low voltage as the power and operating the above principle. It can also be used in charging situations.
