Description
Technical field
The utility model relates to a kind of dust catcher, relates in particular to a kind of alternating current-direct current dual-purpose dust catcher.
Background technology
In the prior art, dust catcher generally all is the dust catcher that power line is arranged, AC power is connected in the motor of dust catcher by power line, make dust catcher work, but this dust catcher is owing to be subjected to the restriction of power line length, thereby being limited in scope of dust suction activity, power line also can be subjected to the winding of furniture etc., uses and inconvenient.
The dust catcher of energy storage type has appearred in market recently, and battery provides energy to direct current generator, but is limited to the volume of dust catcher, the charge capacity of batteries is limited, service time is shorter, even can't continue to finish household cleaning one time, and needing charging midway to use also has inconvenience.
The utility model content
Technical problem to be solved in the utility model provides a kind of alternating current-direct current dual-purpose dust catcher, and two kinds of power supply modes can be provided, and solves the shortcoming that existing dust catcher scope of activities is little and service time is short.
For solving the problems of the technologies described above, the utility model provides a kind of alternating current-direct current dual-purpose dust catcher, comprising:
Housing and place dust collection mechanism, motor of dust collector, power module, the battery module in the described housing and be used to select the mode selection circuit of power supply Alternating Current Power Supply or battery direct current supply;
The output of described power module connects the input of described battery module; The output of described power module and described battery module is connected the input of described mode selection circuit respectively; The output of described mode selection circuit connects the input of described motor of dust collector; The output of described motor of dust collector connects described dust collection mechanism.
The input of described mode selection circuit has a switch, and the other end of described switch is connected with the output of described power module or described battery module.
Described alternating current-direct current dual-purpose dust catcher also comprises an indicator lamp that is arranged in the storage battery power supply loop.
The utility model can make dust catcher have power supply Alternating Current Power Supply or battery direct current supply dual mode by said structure, solves the shortcoming that existing dust catcher scope of activities is little and service time is short.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is an embodiment of structure of the present utility model;
Fig. 2 is a circuit working functional-block diagram of the present utility model;
Fig. 3 is an embodiment of mode selection circuit of the present utility model.
Reference numeral is among the figure, 1, absorbent brush; 2, dust bag; 3, housing; 4, motor of dust collector; 5, power module; 6, battery module; 7, mode selection circuit.
The specific embodiment
As shown in Figure 1, alternating current-direct current dual-purpose dust catcher of the present utility model comprises: housing 3 and place absorbent brush 1, dust bag 2, motor of dust collector 4, power module 5, the battery module 6 in the described housing 3 and be used to select the mode selection circuit 7 of power supply Alternating Current Power Supply or battery direct current supply.
As shown in Figure 2, the output of the power module of alternating current-direct current dual-purpose dust catcher connects the input of battery module; The output of power module and battery module is the input of connection mode selection circuit respectively; The output of mode selection circuit connects the input of motor of dust collector; The output of motor of dust collector connects dust collection mechanism.
When the input of the power module of dust catcher connected external ac power source, its output was that battery module charges.
This moment, the power supply mode of mode selection circuit setting was a power supply Alternating Current Power Supply pattern, was the motor power supply of dust catcher by external power source directly then, further controlled dust collection mechanism and carried out dedusting.The motor of energy storage type dust catcher generally adopts direct current generator, and then the alternating current in the power module at first need carry out " AC-DC " conversion.
When the input of the power module of dust catcher unsettled, when being the deenergization line, the power supply mode of mode selection circuit setting is a battery direct current supply pattern, and then the battery module by inside is the motor power supply of dust catcher, further controls dust collection mechanism and carries out dedusting.
The input of mode selection circuit has a switch, and the other end of this switch is connected with the output of power module or battery module, thereby realizes the switching of above-mentioned two kinds of mode of operations.
Alternating current-direct current dual-purpose dust catcher of the present utility model can also comprise an indicator lamp that is arranged in the storage battery power supply loop, and being used to indicate described dust catcher is power supply Alternating Current Power Supply or battery direct current supply.
Be an embodiment of mode selection circuit of the present utility model as shown in Figure 3.
Ui1 is the input voltage of power module, and Ui2 is the input voltage of battery module, and Uo is the output voltage of mode selection circuit, directly controls motor of dust collector work.When switch S 1 disconnected, the Uo output voltage was 0, and motor of dust collector is not worked.When the S1 switch was selected the input voltage Ui2 of battery module, by the input voltage Ui2 control motor of dust collector work of battery module, this moment, indicator lamp L1 lighted, and showed that present mode is a battery direct current supply pattern.When the S1 switch is selected the input voltage Ui1 of power module, by the input voltage Ui1 control motor of dust collector work of power module.
Above embodiment only is used for illustrating the implementation method of mode selection circuit of the present utility model, is not to restriction of the present utility model, at the circuit structure shown in Fig. 2, the design of other physical circuits can also be arranged according to the utility model.
