Description

Vacuum cleaner

The present invention relates to a kind of vacuum cleaner, it has first parts that are removably installed in second parts, first parts are designed to hand-held device, include an electric fan, a dust storage tank and the circuit that can be switched to power supply by cable, second parts then are designed to the long handle shape, and its upper end is a handle, its lower end then is the suction nozzle that has electronic brush roll or like parts, and handle and suction nozzle interconnect by a middleware.

The multipurpose vacuum cleaner is known, referring to US 5524321, this vacuum cleaner with two separate parts both can be used as common upright vacuum cleaner, and after taking parts away, can be used as canister type vacuum cleaner again, every class vacuum cleaner all has its advantage.Parts of this canister type vacuum cleaner have a dust storage tank and an electric fan, be used as dust collect plant and vacuum source is provided under upright vacuum cleaner or canister type vacuum cleaner pattern, and another parts have a long handle that is hinged on the suction nozzle chamber.Have a motor-driven brush roll in the suction nozzle chamber, motor links to each other with public access mouth in the suction nozzle chamber.Under vertical pattern, the public access mouth interacts with maternal interface in canister type vacuum cleaner, maternal interface then by the circuit communication in canister type vacuum cleaner to external power.Though multipurpose is installed and may be brought advantage when carrying out common cleaning, to carry out when picking up the interim operation of particle in a small amount or dust, installment work is not suitable especially, because vacuum cleaner is very big and very difficult manipulation.In addition, when being mounted to canister type vacuum cleaner, flexible pipe, extension spray lance and suction nozzle must be linked in jar chamber, and this is pretty troublesome and time-consuming.

As everyone knows, when carrying out interim cleaning, adopt hand-held vacuum cleaner.This hand-held vacuum cleaner is small and exquisite, be easy to handle, and has the motor fan parts of battery or power supply power supply.

Also have wireless hand-held vacuum cleaner on the market, see EP 267056, it has independently brush suction nozzle parts, and these parts have a battery that leans against in the hand-held device to drive motor-driven brush roll.This wireless hand-held vacuum cleaner can also change into so-called stick type vacuum cleaner, sees US 4766638, by adding a long handle and traditional suction nozzle that does not have brush roll gets final product.A kind of similar vacuum cleaner that had gone on the market in last year has a wireless handheld component, and it is removably mounted on the long handle.There is a handle upper end of long handle, and there is the suction nozzle of a band brush roll lower end, and when this assembly was fixed on the long handle, brush roll can be by the battery powered motor-driven in handheld component, and dust can be drawn onto in the dust storage tank from the suction nozzle of long handle spare.In this structure, adopted the contact counterpart so that electric current is transported to brush roll from battery between two parts.

The power consumption that the above-mentioned shortcoming that has by battery-driven design is blower motor and brushroll motor must be limited, because the effective electric weight of battery is not very high.

One of purpose of the present invention just provides a kind of cheap vacuum cleaner, the handheld component that both can be used as no brush roll, can be used as the stick type vacuum cleaner that has brush roll again, simultaneously, vacuum cleaner when working with all strength, and power supply electric power can both reach traditional vacuum cleaner level to the treatment effeciency that makes suction and brush roll greatly.Can also use cheap part and simple, safe in the design of being recommended between the contact that has formed between vacuum cleaner two parts.This can be achieved by the device with feature in the claims.

Here describe one embodiment of the present of invention with reference to the accompanying drawings, wherein:

Fig. 1 is the side view under the upright vacuum cleaner pattern,

Fig. 2 is the cutaway view of first parts,

Fig. 3 then is the local amplification view of vacuum cleaner.

As shown in Figure 1, vacuum cleaner has the hand-held device of one first parts 10 forms, and these first parts 10 removably are connected with second parts 11.

These first parts 10 as shown in Figure 2, it has a motor room 12 that removably is connected on the dust storage tank 13.There is a handle 14 this motor room 12, includes a fan part 15, by driving by transformer 17 and the direct current of the electric current power supply of rectifier 18 or the motor 16 of alternating current generator.Transformer will be converted to by the general alternating current at 100～250 volts that cable 19 is supplied from power supply and be lower than 50 volts voltage, and rectifier then becomes alternating current the direct current that is used for above-mentioned purpose.Also have a nozzle openings 20 to form the gas access 21 of a tubulose in the dust storage tank 13, the air that is full of dust flows to dust-storage chamber 13 by this inlet 21.

Dust-storage chamber 13 separates by filter 22 and the inlet 23 that leads to fan assembly.When emptying filter 22, it can be pulled down in dust-storage chamber 13.A control knob 24 is arranged in the motor room, and motor 16 can obtain connecting by it, can contact control knob from handle 14.There is a locking shoulder 25 this motor room, is fixed on second parts 11 by these shoulder 25 first parts 10.First parts also have an interface 26 opening, that have Metal Contact device 27 outwardly, and low-voltage DC can pass to Electical connector 27 through transformer and rectifier by conductor 28.

Second parts 11 are long handle shapes, and its upper end has a handle 29, and when contact to earth in lower end 30, the position height of handle 29 can be very comfortable so that handle vacuum cleaner.Two parts connect by the middleware 31 of a prolongation up and down.There is a chamber 32 lower end 30, includes a nozzle openings 33 and the brush roll 34 in the face of the floor.This chamber 32 is connected rotationally with middleware 31, can be rotated the angle with respect to its qualification.Suction nozzle 33 links to each other by the outlet (not shown) of a passage 35 in chamber 32 with the lower end 16 of the middleware of the nozzle openings 20 of close first parts 10, and this outlet can be used as a bearing of the nozzle openings 20 of first parts 10.Also have a direct current generator 37 in this chamber 32, can drive brush roll 34 by a belt 38.This motor 37 leans against conductor 39 (not shown) on the middleware 31 and is switched on the Metal Contact device 40 on the shoulder 41 that is positioned on middleware 31 sides, so that first parts 10 are when being installed on second parts 11, the Metal Contact device 27 of first parts 10 fits on the Metal Contact device 40 of middleware in the face of first parts 10 for it.This middleware also has a shoulder 42, and it has a lock-button 43 of linking on the stop pin (not shown), and stop pin can connect locking shoulder 25 so that first parts 10 are fixed on second parts 11.

This device is operated by following mode.When vacuum cleaner was used to clean the floor, first parts 10 were fixedly mounted on second parts 11.Cable 19 is received on the flush receptacle, opens control knob 24 afterwards, so that electric current passes to blower motor 16 and transformer 17, also is that low-voltage AC passes to rectifier 18.The electric current that flows out rectifier 18 is supplied with brushroll motor 37 by Metal
