Abstract

The utility model discloses a sweeper with a function of filter core protection in a damp environment. The sweeper comprises a chassis with a driving device, an electric control box, a power supply, a centrifugal fan work unit, a sweeping brush, a filtering and dust collecting box and a filter core, wherein an exhaust opening of the centrifugal fan work unit is connected with the filtering and dust collecting box, the filter core is arranged in the filtering and dust collecting box, the power supply is connected with the electric control box, the electric control box is connected with the sweeping brush, the centrifugal fan work unit and the driving device on the chassis, a function switch is connected between the electric control box and the centrifugal fan work unit in series, and the function switch is an independent toggle switch or a humidity control switch which can be automatically switched off when humidity is larger than a preset humidity value. When water is accumulated on the ground, the filter core can be protected by the means that the function switch is prodded by an operator or the humidity control switch is automatically switched off under the control of a humidity controller, so that the filter core is protected, and the service life of the filter core is prolonged.

Description

Has the sweeper of crossing the filter core defencive function in the wet environment

Technical field

The utility model relates to a kind of floor cleaning equipment, refers to a kind of sweeper of crossing the filter core defencive function in the wet environment that has that can effectively remove dust adsorbed on the filter core especially.

Background technology

Sweeper in the course of the work; for the gas that prevents to suck in dust-absorbing filtering and the caisson is continued to extract out by the centrifugal blower working cell; the air inlet port of being located in the disposal box in the centrifugal blower working cell goes out to be provided with the filter core of crossing that is used to filter dust usually; the filter core excessively of sweeper all is that the cross section is jagged barrel-like structure; and material normally has the fiber of water absorption character; in the time of sweeper work; running into ground sometimes has the situation of ponding; because present sweeper is in work; sweep brush and the continuous operation always of centrifugal blower working cell; the powerful inhalation power that the centrifugal blower working cell produces can be drawn into water droplet crossing on the filter core of sweeper; this can cause sweeper to cross the damage of filter core; and this damage is difficult to recover; this has just caused bigger loss to the user; cause customer using cost to increase; therefore be increased in wet environment or when the wetland general work to crossing the defencive function of filter core; most important for sweeper, also there is not such sweeper to occur in the market.

The utility model content

Technical purpose of the present utility model is for a kind of sweeper with mistake filter core defencive function in the wet environment that can shake dust on the core wall of removing filter core effectively by active is provided.

To achieve these goals, this Floor-sweeping device of the utility model adopts following technical scheme, comprise chassis, electric control box, power supply, centrifugal blower working cell, sweep brush, the filtration disposal box that has drive unit and cross filter core, inlet scoop, centrifugal blower working cell is connected, crosses filter core with the filtration disposal box and is located in the filtration disposal box, power supply is connected with electric control box, this electric control box and sweep brush, centrifugal blower working cell are connected with drive unit on the chassis, are in series with a functional switch between electric control box and centrifugal blower working cell.

Of the present utility model have in the wet environment in the sweeper of crossing the filter core defencive function, and described functional switch is toggle switch independently.

Of the present utility model have in the wet environment in the sweeper of crossing the filter core defencive function, and described functional switch is the humidity gauge tap, this humidity gauge tap in humidity automatic disconnection during greater than default humidity value.

Of the present utility model have in the sweeper of crossing the filter core defencive function in the wet environment, and the scope of described default humidity value is 70%RH-99%RH.

Of the present utility model have in the sweeper of crossing the filter core defencive function in the wet environment, and the scope of described default humidity value is 95%RH-99%RH.

The utlity model has the sweeper advantage compared with prior art of crossing the filter core defencive function in the wet environment is; the functional switch of between electric control box and centrifugal blower working cell, having connected; this functional switch can be arranged on the function control panel of sweeper; or a kind of humidity gauge tap is set; the humidity sensor of humidity gauge tap is arranged near the sweep brush; when there is ponding on ground; operating personnel can be by stirring functional switch; or under the control of humidity controller automatic disconnection humidity gauge tap; playing the purpose of protecting filter core, thereby the life-span of the use of filter core can be prolonged effectively.

For ease of explanation detailed content and the technology relevant, below describe with regard to conjunction with figs. now with the utility model.

Description of drawings

Fig. 1, be the circuit theory diagrams that have in the wet environment sweeper of crossing the filter core defencive function of first kind of embodiment of the utility model;

Fig. 2, be the circuit theory diagrams that have in the wet environment sweeper of crossing the filter core defencive function of second kind of embodiment of the utility model.

The specific embodiment

Please refer to illustrated in figures 1 and 2; be two kinds of preferred embodiments of the present utility model; in the present embodiment; sweeper with mistake filter core defencive function in the wet environment of the present utility model comprises the chassis that has drive unit; electric control box; power supply 100; centrifugal blower working cell 102; sweep brush; filter disposal box and cross filter core; the inlet scoop of centrifugal blower working cell 102 is connected with the filtration disposal box; crossing filter core is located in the filtration disposal box; power supply is connected with electric control box; this electric control box and sweep brush; centrifugal blower working cell 102 is connected with drive unit on the chassis, is in series with a functional switch between electric control box and centrifugal blower working cell 102.This functional switch can be toggle switch 101 independently, this toggle switch 101 is arranged on the function control panel of sweeper, operation with the handled easily personnel, when on the ground of work ponding being arranged, close this toggle switch 101, under moist environment,, therefore only keep the sweep brush rotation just can clean the road surface because there is not dust.

Further, described functional switch also can be humidity gauge tap 103, or adopt the Temperature and Humidity Control switch to substitute, when around ambient humidity during greater than the default default humidity value of this humidity gauge tap 103, these humidity gauge tap 103 meeting automatic disconnections, to disconnect the work of centrifugal blower working cell, the scope 70%RH-99%RH of the default humidity value of common this humidity gauge tap 103, in order to guarantee that this humidity gauge tap 103 in use has higher sensitivity, the default humidity value of humidity gauge tap 103 is controlled between the 95%RH-99%RH, in order to reflect real external environment condition situation, this humidity gauge tap is separated humidity sensor 106 separately usually, near and being arranged on the sweep brush of this sweeper, so that the true environment situation in the reflection external world that can be sensitiveer.
