Due to the influence of vehicle exhaust, dust adhesion and other factors, the cleaning of public facilities has become one of the key points of reflecting the appearance of the city, so cleaning and suction trucks have gradually become popular. The cleaning and suction truck is a new type of sanitation vehicle that collects, transfers, cleans and transports sludge and domestic sewage to avoid secondary pollution, and the cleaning truck is loaded with a box body, which stores clean water, as described in the Chinese patent CN210827804U entitled A Dual-Purpose Box for Cleaning and Suction Trucks: The sewage tank is square, and a water inlet three is provided on the top, and a sewage tank cleaning structure is also installed; the above-mentioned existing structure can obviously clean the sewage tank better and facilitate the injection of clean water, but it cannot meet the needs of multiple scenarios. That is, when the sewage tank is full, the above structure can only be discharged through a water pipe. If there are large debris inside the sewage tank, normal sewage discharge cannot be completed, causing trouble in use. For this reason, a multifunctional box for a deep cleaning vehicle is proposed.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a multifunctional box for deep cleaning vehicles, which has the following beneficial effects:

[0016] 1. The multifunctional box for deep cleaning vehicles integrates a sewage tank and a clean water tank. It can meet the clean water needs of deep cleaning vehicles and also provide a cavity for collecting sewage. At the same time, it is equipped with two sewage discharge methods: a discharge butterfly valve and directly opening the tailgate to discharge. Operators can choose the way to discharge sewage according to local conditions to avoid secondary pollution caused by inappropriate sewage discharge methods; at the same time, if there are large debris inside the sewage tank that blocks the discharge butterfly valve, the box can also be transported to the designated area and the tailgate can be opened for sewage discharge, which is more flexible.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A multifunctional box for deep cleaning vehicles includes an integrated box. A clean water tank 1 and a sewage tank 3 are arranged inside the integrated box. A sewage suction pipe 4 for entering sewage is fixedly installed on the input end of the sewage tank 3. A fan 5 is fixedly installed on the top of the sewage tank 3, and the fan 5 blows air upward. An isolation component is arranged at the position between the fan 5 and the sewage suction pipe 4 inside the sewage tank 3. A float switch 7 electrically connected to the fan 5 is arranged on the inner wall of the top of the sewage tank 3, and the float switch 7 is suspended inside the sewage tank 3. The clean water tank 1 is used to provide clean water required for the operation, and the sewage tank 3 is used to temporarily store sewage generated during the operation. When the fan 5 is started, a negative pressure cavity will be formed inside the sewage tank 3. The isolation component can isolate solid debris and even sewage from entering the inside of the fan 5 to cause damage to it. When the water level inside the sewage tank 3 reaches a certain height, the float switch 7 is triggered, and the fan 5 stops working to prevent the sewage water level from exceeding the upper end of the sewage suction pipe 4, causing sewage backflow.

[0025] Furthermore, the isolation component includes a waterproof rubber 9 and an air suction vent mesh 8, the air suction vent mesh 8 is located at the top of the sewage tank 3, and the position of the air suction vent mesh 8 corresponds to the position of the air suction vent of the fan 5. The waterproof rubber 9 is located on the inner wall of the sewage tank 3, and the waterproof rubber 9 isolates the inlet of the fan 5 from the outlet of the sewage suction pipe 4 to prevent the fan 5 from directly sucking sewage during the operation process, so that the sewage is sucked into the fan 5 and causes damage. The air suction vent mesh 8 mainly prevents large pieces of garbage from being sucked into the fan 5.

[0026] Furthermore, a water inlet 2 is fixedly installed inside the integrated box, and a water inlet pipe is provided inside the clean water tank 1, and the water inlet pipe is connected to the water inlet 2. An external water source is connected to the clean water tank 1 through the water inlet 2 to meet the need of injecting clean water.

[0027] Furthermore, a tailgate 11 is provided on one side of the integrated box body, and the bottom inner wall of the sewage tank 3 is an inclined wall surface inclined toward the tailgate 11 , so that the sewage inside the sewage tank 3 can be directly discharged by opening the tailgate 11 .

[0028] Furthermore, a discharge butterfly valve 12 is fixedly installed on the tailgate 11. When the working environment is an area such as a square where it is not suitable to directly discharge sewage, the discharge butterfly valve 12 can be opened to connect the water pipe and discharge the sewage directly into the sewer pipe. At the same time, a sewage tank spray rod 10 is arranged inside the sewage tank 3, and the sewage tank spray rod 10 is used to flush the sewage tank 3 after the operation. In addition, a hose reel 6 is fixedly installed inside the integrated box, and the hose reel 6 is located at the top of the sewage tank 3, so as to facilitate the connection of a spray gun or other manual operations.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
