As shown in fig. 1 to 8, the invention relates to a sewage suction device, which comprises a sewage tank 1, a tank cover 11 and a tank body 12, wherein a sewage cavity 14 for accommodating sewage is formed in the tank body 12, an opening 13 communicated with the sewage cavity 14 is arranged at the upper part of the tank body 12, and the tank cover 11 covers the opening 13 of the tank body 12; the air suction mechanism 2 comprises a fan 21 and an air filter 22, wherein the fan 21 is communicated with the sewage cavity 14 through the air filter 22 so as to generate negative pressure in the sewage cavity 14; and the sewage suction mechanism 3 comprises a water suction rake assembly, a filtering assembly 31 and a sewage suction pipe 32, wherein the filtering assembly 31 comprises a filtering basket 311 arranged at the opening 13 of the box body 12 and a basket cover 312 for covering the filtering basket 311, one end of the sewage suction pipe 32 is communicated with the inside of the filtering basket 311, and the other end of the sewage suction pipe is communicated with the water suction rake assembly so as to transmit negative pressure in the sewage cavity 14 to the water suction rake assembly.
In the invention, when the sewage suction device works, the fan 21 is started to enable the sewage cavity 14 in the box body 12 to be in a negative pressure state, the negative pressure state is transmitted to the water suction raking assembly through the sewage suction pipe 32 to suck sewage and domestic garbage on the ground through the water suction raking assembly, the sewage enters the sewage cavity 14 through the sewage suction pipe 32, the domestic garbage is filtered in the filter basket 311 to realize the separation of the sewage and the domestic garbage, the domestic garbage is prevented from entering the sewage cavity 14, and the basket cover 312 can prevent the sewage from splashing to the bottom of the box cover 11, so that the subsequent cleaning work can be facilitated, and the blockage of a sewage discharge pipeline can be prevented; simultaneously, the air cleaner 22 that sets up between fan 21 and the sewage chamber 14 can absorb the steam in the sewage chamber 14 at fan 21 operation in-process, reduces the steam that gets into fan 21, avoids fan 21 to receive the corruption, guarantees fan 21's life.
In this embodiment, the lower portion of the basket cover 312 is provided with a water baffle 3121 protruding toward the bottom of the filter basket 311, a side wall of the filter basket 311 opposite to the water baffle 3121 is provided with a through hole 3111 through which one end of the soil suction pipe 32 passes, and one end of the soil suction pipe 32 is disposed toward the water baffle 3121.
The through-hole 3111 that the soil pick-up pipe 32 passes through the filter basket 311 lateral wall stretches into in the filter basket 311, soil pick-up pipe 32 is towards breakwater 3121, when soil pick-up pipe 32 spun sewage strikes on breakwater 3121, the most sputter of sewage is regional in basket cover 312 lower part, and the steam that produces after the sputtering can condense into the drop of water in basket cover 312 lower part, can reduce the production of steam, also reduce steam diffusion to in the sewage chamber 14, and then reduce the steam that gets into in the air cleaner 22, be favorable to increasing the life-span of air cleaner 22, need not frequent change air cleaner 22, the use cost of consumptive material has also been saved.
In other embodiments, the water baffle 3121 may be curved to guide the sewage sprayed from the sewage suction pipe 32, so as to reduce the splashing degree of the sewage when the sewage collides with the water baffle 3121, thereby reducing the generation of water vapor after splashing, and facilitating the improvement of the service life of the air filter 22 and the fan 21.
One side area of the basket cover 312 is downwards recessed to form a groove 3122, the other side area of the basket cover 312 is upwards raised to form a boss 3123, the stepped wall where the groove 3122 and the boss 3123 are intersected forms a water baffle 3121, the lower portion of the basket cover 312 and the side position corresponding to the boss 3123 are provided with a vertical positioning plate 3124, and one end of the vertical positioning plate 3124 is correspondingly attached to the end of the water baffle 3121. The vertical positioning plate 3124 may be disposed on only one side of the boss 3123, or may be disposed on both sides of the boss 3123.
The one side region of basket cover 312 upper portion undercut forms recess 3122, and the other side region is upwards protruding and forms boss 3123, and this embodiment is through the breakwater mode of the whole undercut of one side of basket cover 312 and the formation of epirelief, and the breakwater belongs to a part of the recess lateral wall, can receive the support of adjacent recess lateral wall at least, and compare with the mode that directly sets up the monolithic breakwater in the lower part of basket cover 312, the anti sewage attack ability is stronger. Through the setting of vertical locating plate 3124, vertical locating plate 3124 corresponds the effect that plays the stopping at the both ends of breakwater 3121 to reduce the outside sputter of sewage, in further reducing steam diffusion to sewage chamber 14, thereby increase air cleaner 22 and fan 21's life.
In addition, one side region of the basket cover 312 is recessed downward to form a groove 3122, and the other side region of the basket cover 312 is raised upward to form a boss 3123, which can form a structure convenient for the user to grasp, so as to facilitate the later opening of the basket cover 312 by the user.
Installing port 111 that is located opening 13 is seted up on box 12 upper portion, the interior week of installing port 111 is equipped with first step 112, the periphery on straining basket 311 upper portion is equipped with outer edge 3112, strain basket 311 embedding installing port 111 in, and the lower part of straining basket 311 stretches into the sewage intracavity of box 12, strain outer edge 3112 butt of basket 311 on first step 112, basket lid 312 imbeds in installing port 111, and then can convenience of customers take out straining basket 311, so that the rubbish of straining basket 311 is strained to the clearance, two vertical locating plate 3124 outsides of basket lid 312 lower part correspond and are close to the inboard of straining basket 311, and simultaneously, the lateral wall correspondence of lower boss 3125 is pressed close to with straining basket 311, so as to play limiting displacement for basket lid 312 on straining basket 311, make basket lid 312 can stably cover and establish on straining basket 311 upper portion.
The bottom wall of the filter basket 311 is opened with a filter hole 3113, and the side wall of the filter basket 311 is opened with an air hole 3114, specifically, the filter hole 3113 may be a circular hole, and the air hole 3114 may be a waist-shaped hole.
Set up the round hole bottom straining basket 311 and can prevent that the rubbish of straining basket 311 bottom from getting into in the sewage chamber 14 because of gravity, the waist type hole is in order to reduce the resistance of breathing in, ensure the negative pressure state in straining basket 311, in order to ensure the negative pressure state of suction pipe 32, and, because rubbish can drop to straining basket 311 bottom under the effect of gravity, so rubbish is difficult for falling out from the waist type hole, what more, because breakwater 3121 blocks the effect, can let rubbish drop in straining basket 311 middle part region after blockking, make rubbish more difficult to get into in the sewage chamber 14 through the waist type hole.
In this embodiment, the filter assembly 31 and the air filter 22 are located at one side region of the upper opening 13 of the case 12, and the other side region of the upper opening 13 of the case 12 forms a purge port.
That is, by integrating the filter assembly 31 and the air filter 22 at one side of the upper opening 13 of the foul water tank and the other side being the cleaning opening of the tank body 12, the aperture of the cleaning opening can be greatly increased to facilitate the cleaning of the foul water chamber 14 by the user at a later stage.
