Referring to fig. 1, the present application provides a blowdown filtering device comprising: a housing assembly 10 and a filter element disposed within the housing assembly 10; the housing assembly 10 is provided with a total water outlet 10a and a total water inlet 10b.
The cartridge includes a first filter structure 22 and a second filter structure 26; the first filtering structure 22 includes a flow guiding portion 220 and a water filtering portion 240; the water filtering part 240 is provided with a filter element water outlet 240a communicated with the total water outlet 10a; the diversion section 220 is provided with a plurality of diversion water outlets 220a and a filter core water inlet 220b communicated with the total water inlet 10b.
A flow passage communicated with the water filtering part 240 and the split water outlet 220a is formed between the inner wall of the shell assembly 10 and the first filtering structure 22; the second filtering structure 26 is located in the flow passage and is disposed between the water filtering portion 240 and the split water outlet 220 a.
The opening side of the diverting outlet 220a is oriented toward the direction of gravity.
For example, the opening side of the diversion water outlet 220a is flush with the surface of the diversion portion 220, or protrudes downwards from the surface of the diversion portion 220 in the vertical direction, so that the opening side of the diversion water outlet 220a is biased towards the gravity direction, and further, impurities in the water flow can be prevented from flowing back into the diversion portion 220 from the diversion water outlet 220a under the action of gravity.
The first filter structure 22 and the second filter structure 26 in the cartridge may be integrally formed or may be separate pieces that interface with each other. The first filtering structure 22 including the flow guiding portion 220 and the water filtering portion 240 may be a columnar component, one end of which is the flow guiding portion 220, and the other end of which is the water filtering portion 240. For example, a diversion baffle 220c may be disposed in the diversion portion 220 and located at the diversion water outlet 220a to form a diversion surface, preferably an inverted cone type "V" diversion baffle 220c, so as to reduce the resistance to water, so that the water flow can flow out of the diversion water outlet 220a more smoothly. For example, when water flow (as indicated by the arrow in fig. 1) enters the total water inlet 10b, it flows out into the inflow channel from the split water outlet 220a of the diversion portion 220. Because the second filtering structure 26 is located between the water filtering portion 240 of the first filtering structure 22 and the split water outlet 220a and is located in the flow channel, the water flow can flow out after being filtered by the second filtering structure 26, the water flow needs to change the direction of the water flow to enter the water filtering portion 240 from the flow channel, and the water flow speed is slowed down, so that impurities in the water flow are more favorable to be blocked outside the water filtering portion 240 again, and then the water flows out from the water outlet 240a of the filter element of the water filtering portion 240 and the total water outlet 10 a.
In the blowdown filtering device of the embodiment of the application, the filter element arranged in the shell assembly 10 comprises a first filtering structure 22 and a second filtering structure 26; the first filter structure 22 includes a flow guiding portion 220 and a water filtering portion 240. And a flow passage communicated with the water filtering part 240 and the diversion water outlet 220a is formed between the inner wall of the shell assembly 10 and the first filtering structure 22, wherein the second filtering structure 26 is arranged between the water filtering part 240 and the diversion water outlet 220a and is positioned in the flow passage, and the opening side of the diversion water outlet 220a faces to the direction of deflection gravity. When the water flows from the main water inlet 10b to the split water outlet 220a and enters the flow passage, the water is filtered by the second filtering structure 26 under the blocking of the second filtering structure, then enters the water filtering part 240 in the first filtering structure 22 through the flow passage for secondary filtration, and then flows out through the filter element water outlet 240a and the main water outlet 10 a. In the blowdown filtering device of the embodiment of the application, the water flow passes through the second filtering structure 26 in the flow passage under the action of the flow guiding part 220 and then enters the water filtering part 240, so that the flow velocity of the water flow is slowed down, impurities in the water flow are filtered out of the water filtering part 240 of the first filtering structure 22 while the cleanliness of the flow passage at the other side of the second filtering structure 26 is further improved. The application effectively optimizes the filtering effect of the sewage discharging and filtering device, improves the water filtering and purifying capability, has simpler structure, is easy to realize, has lower cost, and is convenient to be applied to most water using equipment, such as wall hanging furnaces, water heaters and the like.
Referring to fig. 1, in a specific embodiment, the second filter structure 26 is sleeved on the first filter structure 22, and the second filter structure 26 forms a predetermined angle with the first filter structure 22; the predetermined angular range is [80 °,100 ° ].
For example, the predetermined angle is, for example, 85 ° or 95 °, preferably 90 °, i.e. the first filter structure 22 and the second filter structure 26 may be perpendicular to each other.
According to the sewage draining and filtering device provided by the embodiment of the application, after the water flow passes through the second filtering structure 26 in the flow channel at a certain flow speed to finish one-time filtering, the water flow direction is changed to enter the water filtering part 240 of the first filtering structure 22, so that the flow speed of the water flow is slowed down, and impurities in the water are filtered out of the filter element. In the embodiment of the application, the preset angle range is reasonable and moderate, so that the structural installation and arrangement between the first filtering structure 22 and the second filtering structure 26 are stable and firm, and water flow can be effectively and smoothly passed, the water filtering capacity is improved, and the water quality purifying effect is optimized.
Referring to fig. 1 and 2, in a specific embodiment, the filter cartridge further comprises: umbrella-type baffle 30; umbrella baffle 30 is positioned between diverter outlet 220a and cartridge inlet 220b.

Further, the umbrella baffle 30 also slows the flow of water, helping to further filter out impurities from the second filter structure 26. The umbrella-shaped baffle 30 is relatively perfect in structure and easy to realize, impurities and moisture in water flow can be effectively layered, and the filtering water purifying capacity of the sewage draining and filtering device is improved.

At this time, as shown in fig. 5, the first sealing ring 50 may be separated from the trapway along with the check valve 40, the trapway is in an open state, and the filtered impurities 300 may be discharged from the trapway. When the sewage is not required, the first clamping portion 40a of the check valve 40 is moved from the transverse portion 108c to the longitudinal portion 104c, and the check valve 40 can be pulled in the longitudinal direction by an external force until the sewage channel is sealed by the first sealing ring 50, as shown in fig. 4.

A resilient member 60 is disposed in the trapway between the outer wall of the check valve 40 and the inner wall of the housing assembly 10 to urge the check valve 40 through the first seal 50 to seal the trapway.
For example, during the sewage draining, the check valve 40 can be pushed toward the inside of the housing assembly 10, at this time, one end of the elastic member 60 abuts against the sewage draining port on the sewage draining channel near the diversion water outlet 220a, and at the same time, the first sealing ring 50 is in a compressed state under the reaction force of the sewage draining port and the check valve 40, at this time, the first sealing ring 50 is separated from the sewage draining channel, and the sewage draining and filtering device is in an open state (as shown in fig. 5) for draining sewage.
