Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The invention provides a filtering device, which is provided with a sealed cavity, wherein the sealed cavity is provided with a water inlet, a water outlet and a sewage discharge outlet, a filtering unit is arranged at the water outlet, a sewage draining outlet is arranged close to the water inlet side of the filtering unit, the sewage draining outlet of the sealed cavity is sealed by a switch component, water enters the sealed cavity and is discharged after being filtered by the filtering unit, the filtered impurities are accumulated above the filtering unit, when the filtering unit is blocked due to the excessive accumulated impurities, when the internal pressure of the sealed cavity is overlarge, the switch component opens the sewage draining port, impurities are discharged out of the filtering device through the sewage draining port under the flushing of water flow, when the pressure in the sealed cavity is reduced, the switch component seals the sewage draining port, and the filtration and collection of impurities are continuously carried out, thereby realizing the automatic collection and the clearance of impurity, having made things convenient for user's use greatly, effectively preventing filter equipment's jam.
The first embodiment is as follows:
The embodiment provides a filtering device, as shown in fig. 1, the filtering device has a sealed cavity 1, a water inlet 2 is opened at one side of the sealed cavity 1, a sewage outlet 3 is opened at one side of the sealed cavity 1 opposite to the water inlet 2, a water outlet 4 is also opened at the bottom of the sealed cavity 1, and a filtering unit 5 for filtering water, such as a filter screen and a filtering membrane, is arranged at the water outlet 4.
The drain 3 is sealed through switch module, and in this embodiment, switch module includes baffle 6 and sets up in the outside first spring 7 of seal chamber 1, and it is fixed that support 8 is passed through to first spring 7 one end, and other end connection baffle 6, under the spring action of first spring 7, baffle 6 seals drain 3.
And a reverse flow prevention device is also arranged at the water inlet 2 to prevent water entering the sealed cavity 1 from flowing backwards. In this embodiment, the backflow prevention device is an elastic hose 9 with high recovery deformation capability, and the open end of the backflow prevention device keeps the inner wall of the hose attached together in a state that water does not flow out, so that a sealed state is formed, and water cannot flow back even under the action of high pressure; when water is discharged, the hose is deformed by the pressure of water inside the hose, and the inner walls of the hose are separated to form passages, so that the water passes through the passages.
This filter equipment's working process does, water gets into seal chamber 1 by water inlet 2 in, discharge by delivery port 4 after filter unit 5 filters, and filterable impurity is amasss there is filter unit 5's top, when filter unit 5 top accumulated impurity leads to filter unit 5 to block up too much, water reenters seal chamber 1 in, and can not flow back under the effect of anti-reflux device, make the pressure in seal chamber 1 too big, when pressure is greater than first spring 7 when the elasticity of baffle 6, first spring 7 produces deformation under the effect of pressure, baffle 6 opens drain 3, impurity is through drain 3 discharge filter equipment under the washing away of rivers, thereby make the pressure in seal chamber 1 reduce, baffle 6 gets back to drain 3 department under the effect of the elasticity of first spring 7, seal drain 3, continue to carry out filtering work.
in order to facilitate the discharge of impurities, the filtering unit 5 is obliquely arranged and one end close to the sewage draining outlet 3 is lower than one end far away from the sewage draining outlet 3, and the upper surface of one end, close to the sewage draining outlet 3, of the filtering unit 5 is flush with the bottom edge of the sewage draining outlet 3, so that high-pressure water in the sealed cavity 1 is flushed along the inclined plane of the filtering unit 5, and the impurities are cleaned more thoroughly.
In order to prevent the filtering device from flushing the baffle 6 by the water flow of the water inlet 2 when the filtering device is normally used for filtering, the water inlet 2 and the sewage discharge outlet 3 are arranged in a staggered way.
The upper surface of one end of the filtering unit 5 close to the sewage draining exit 3 is not limited to be flush with the bottom edge of the sewage draining exit 3, and can also be positioned between the top edge and the bottom edge of the sewage draining exit 3, so that impurities can be smoothly discharged; the backflow preventing means is not limited to the elastic hose 9, but may be other means for preventing the backflow of water, such as a check valve, etc.
Example two:
The embodiment provides a filtering device, as shown in fig. 2, the structure of the filtering device is basically the same as that of the embodiment, the filtering device is provided with a sealed cavity 1, one side of the sealed cavity 1 is provided with a water inlet 2, one side of the sealed cavity 1 opposite to the water inlet 2 is provided with a sewage discharge outlet 3, the bottom of the sealed cavity 1 is also provided with a water outlet 4, a filtering unit 5 for filtering water is arranged at the water outlet 4, and the sewage discharge outlet 3 is closed through a switch assembly.
The difference lies in that the switch assembly of this embodiment is including setting up in solenoid valve 10 of drain 3 department and setting up the pressure switch in seal chamber 1, and when the pressure in seal chamber 1 reached a definite value, pressure switch control opened solenoid valve 10, opened drain 3 and carried out the blowdown. In this embodiment, the pressure switch includes a second spring 11 with one end fixed on the inner side of the top wall of the sealed cavity 1, a reed 12 is sleeved in the second spring 11, the live wire 13 of the electromagnetic valve 10 is arranged above the reed 12, and the reed 12 leaves the live wire 13 of the electromagnetic valve 10 under the elastic force of the second spring 11.
This filter equipment's working process is similar to the embodiment, and when the pressure in seal chamber 1 was too big, second spring 11 produced deformation under the effect of pressure, and the live wire 13 of switch-on solenoid valve 10 is moved up on reed 12, and solenoid valve 10 opens, opens drain 3 and carries out the blowdown to make the pressure in seal chamber 1 reduce, reed 12 leaves live wire 13 under second spring 11's the elastic force effect, closes solenoid valve 10, continues to carry out filtering work.
The pressure switch can also be replaced by a pressure sensor, the pressure sensor and the solenoid valve 10 are connected to a controller, a preset pressure is set in the controller, the controller controls the solenoid valve 10 to be opened when the pressure value detected by the pressure sensor is higher than the preset pressure, and the controller controls the solenoid valve 10 to be closed when the pressure value detected by the pressure sensor is equal to or lower than the preset pressure.
example three:
the present embodiment provides a washing machine, as shown in fig. 3, which includes a cabinet 14, an outer tub 15 and an inner tub 16 provided in the cabinet 14, a circulation pump 17, and a filter device 18 as described in the first or second embodiment. The outer cylinder 15 is provided with a water inlet pipe 19.
