[0038] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0039] like Figure 1-Figure 21 As shown, a disinfection equipment with a sewage tank is mainly composed of a panel 1, a disinfection liquid tank 2, a frame 3, a fan 6, a spray and suction head 7, a sewage tank 4, and a water pump 12, wherein the frame is used to support the entire disinfection equipment, the panel is used to control the disinfection equipment, the disinfection liquid tank is mainly used for the preparation of disinfectant and the temporary storage of the prepared disinfectant, the sewage tank is mainly used for recovering the used disinfectant, the spray and suction head is mainly used for spraying the disinfectant onto the objects that need to be disinfected and can recover the sprayed disinfectant, the fan is arranged at the bottom of the sewage tank 4 mainly for keeping the sewage tank at a negative pressure, so that the sewage tank can recover the used disinfectant, wherein the spray and suction head adopts the existing technology, which will not be repeated here.

[0040] The cleaning liquid tank 2 is provided with a first liquid level sensor for detecting the height of the cleaning liquid in the cleaning liquid tank 2 and a first emptying sensor for detecting whether there is cleaning liquid in the cleaning liquid tank 2. The cleaning liquid tank 2 is provided with a first liquid inlet 2a for allowing the cleaning liquid to enter and connected to the first liquid inlet pipe 8, and a first liquid outlet 2b for allowing the cleaning liquid to flow out and connected to the first liquid outlet pipe 9. A second liquid level sensor for detecting the height of the cleaning liquid in the cleaning tank 4 and a second emptying sensor for detecting whether there is cleaning liquid in the cleaning tank 4 are arranged on the sewage tank 4. At the same time, a second liquid inlet 4a for recovering the cleaning liquid and connected to the discharge channel of the spray and suction head and a second sewage outlet 4b for discharging the cleaning liquid and connected to the second liquid discharge pipe 17 are arranged on the sewage tank 4. Water pumps 12 for realizing liquid flow are arranged on the first liquid inlet pipe 8, the first liquid outlet pipe 9 and the second liquid discharge pipe 17, wherein the water pump on the first liquid inlet pipe 8 is marked as 12a, the water pump on the first liquid outlet pipe 9 is marked as 12b, and the water pump on the second liquid discharge pipe 17 is marked as 12c.

[0041] Due to the coordinated use of the first liquid level sensor and the water pump on the first liquid inlet pipe, the operation in the cleaning liquid tank during use is as follows: when the liquid level in the cleaning liquid tank reaches a low preset value, the corresponding water pump works to allow cleaning liquid to enter the cleaning liquid tank; when the liquid level in the cleaning liquid tank reaches a high preset value, the corresponding water pump stops working and stops the liquid inlet into the cleaning liquid tank, thereby realizing automatic inflow and outflow of cleaning liquid in the cleaning liquid tank, and maintaining the liquid level in the inlet tank between the low preset value and the high preset value, thereby ensuring that the cleaning liquid tank can always supply the normal use of the spray and suction head. When used for the first time, cleaning can only be performed when the liquid level in the cleaning liquid tank reaches the low preset value.

[0042] In the present application, since the sewage tank is in a negative pressure state during the disinfection, in order to ensure the normal discharge of the disinfection liquid in the sewage tank, part of the disinfection liquid is retained in the second drain pipe after the second drain pipe is drained. At this time, the disinfection liquid in the second drain pipe is connected with the disinfection liquid in the sewage tank, so that the drainage of the second drain pipe is not affected by the negative pressure in the sewage tank. Specifically, the operation of the sewage tank is as follows: under the condition that there is no disinfection liquid in the second drain pipe, that is, when the disinfection equipment is used for the first time, when the disinfection liquid in the sewage tank reaches a low predetermined value, the entire disinfection equipment is suspended. The suspension here refers to the suspension of the fan and the water pump on the first liquid outlet pipe, so that the air pressure in the sewage tank is restored from below atmospheric pressure to atmospheric pressure, and then the water pump on the second liquid outlet pipe works, so that there is disinfection liquid in the entire second drain pipe, and the fan and the water pump on the first liquid outlet pipe continue to work until the disinfection liquid in the sewage tank is lower than the low predetermined value, and the water pump on the second liquid outlet pipe stops working. Under the condition that there is disinfectant in the second drain pipe, when the disinfectant in the sewage tank is higher than the lower preset value, the water pump on the second drain pipe works to discharge the disinfectant in the sewage tank through the second drain pipe. When the disinfectant in the sewage tank is lower than the lower preset value, the water pump on the second drain pipe stops working. When the height of the disinfectant in the sewage tank reaches the higher preset value, the disinfection equipment automatically stops disinfection to protect the fan.

[0043] In this embodiment, two fans 6, two spraying and suction heads 7 and two sewage boxes 4 are provided, each spraying and suction head 7 is correspondingly placed in an accessory box 5 provided on the frame 3, and the two accessory boxes 5 are respectively provided on the left and right sides of the frame 3, and the two sewage boxes 4 are arranged side by side at the upper front position of the frame 3, the cleaning liquid box 2 is provided in the frame 3 and is located at the rear side of the sewage box 4, and the cleaning liquid box 2 and the two sewage boxes 4 are provided between the two accessory boxes 5, and the panel 1 is provided on the top surface of the frame 3. In order to ensure that the two spraying and suction heads work independently, the water pumps on the two second liquid discharge pipes 17 are provided separately, and at the same time, two first liquid outlets 2b connected to the corresponding first liquid outlet pipes 9 are provided on the cleaning liquid box 2, and each first liquid outlet pipe 9 is provided with a corresponding water pump 12.

[0044] In order to facilitate the removal and use of the spray head in the accessory box, an accessory box door 11 is hinged on the left and right sides of the panel 1 at positions corresponding to the accessory box 5, and a door handle 11a is provided on the accessory box door 11 for easy opening.

[0045] The first liquid inlet 2a is arranged near the upper end of the cleaning liquid tank 2, and the two first liquid outlets 2b are arranged at intervals at the bottom of the cleaning liquid tank 2. To ensure that the two first liquid outlet pipes can discharge liquid normally when the cleaning equipment is tilted, the two first liquid outlet pipes 9 are connected through the intermediate pipe 10 between the water pump 12 and the cleaning liquid tank 2. To facilitate the inflow and outflow of liquid from the sewage tank, the second liquid inlet 4a is arranged at the upper position of the front side of the sewage tank 4, and the second sewage outlet 4b is arranged on the corresponding bottom surface of the sewage tank 4.

[0046] In this embodiment, two liquid inlet interfaces 1a for connecting to the water inlet channel in the spray and suction head are arranged at intervals on the left and right sides on the front side of the panel 1, and the end of each first liquid outlet pipe 9 is respectively connected to the corresponding liquid inlet interface 1a. For the convenience of use, a control panel is also provided on the panel 1, and two first buttons for respectively realizing the operation or suspension of the two spray and suction heads, a second button for realizing the emptying of the disinfectant liquid, and a third button for realizing the emptying of the sewage tank are provided on the control panel, and a controller for receiving sensor signals and controlling whether the water pump 12 and the fan 6 are working is provided below the control panel.

[0047] After pressing any of the first buttons, when the corresponding spray and suction head enters the disinfection stage, the disinfection liquid tank and the corresponding sewage tank both work according to the above process, and at the same time, the water pump on the corresponding first liquid outlet pipe and the fan on the corresponding sewage tank both work. After pressing any of the first buttons, when the corresponding spray and suction head enters the pause disinfection stage, the corresponding sewage tank stops discharging liquid, and at the same time, the water pump on the corresponding first liquid outlet pipe and the fan on the corresponding sewage tank both stop working, so that the corresponding spray and suction head stops disinfection. Only when the two second buttons are pressed at the same time, so that the two spray and suction heads enter the pause disinfection stage, the disinfection liquid tank stops filling liquid.

[0048] When the second button is pressed, the water pump on the first liquid inlet pipe and the water pumps on the two first liquid discharge pipes work, so that the cleaning liquid in the cleaning liquid tank is discharged. At this time, in order to prevent pollution, the spray head is directly inserted into the foldable sewage bag. When the first emptying sensor detects that the cleaning liquid tank is empty, the water pump on the first liquid inlet pipe and the water pumps on the two first liquid discharge pipes stop working. The first emptying sensor may not be provided, and the water pump on the first liquid inlet pipe and the water pump on the two first liquid discharge pipes can be directly stopped after working for a period of time. When the third button is pressed, the fan of the sewage tank stops working, and the water pumps on the two second liquid discharge pipes work at the same time. When the second emptying sensor detects that the cleaning liquid in the corresponding sewage tank is empty, the water pumps on the two second liquid discharge pipes stop working. The second emptying sensor may not be provided, and the water pumps on the second liquid discharge pipes can be directly stopped after working for a period of time.

[0049] Since the cleaning liquid tank does not need to maintain negative pressure, in the present application, an opening communicating with the outside is provided at the top of the cleaning liquid tank. At the same time, to facilitate the preparation of the cleaning liquid, an inlet for adding cleaning powder or cleaning liquid is provided at the position corresponding to the opening 2c on the panel 1. A filter 13 and a cover plate 14 are provided at the inlet. The filter is inserted at the inlet, and the cover plate covers the filter. A handle is provided at the upper end of the filter for convenient removal of the filter for cleaning. To prevent the cleaning liquid from spilling, the bottom of the panel can just fit tightly against the top of the cleaning liquid tank.

[0050] In order to facilitate temporary support of the spray head during use, two telescopic rods 15 are arranged at intervals on the left and right sides near the front side of the frame 3. They are mainly composed of a number of telescopic units that are sequentially socketed from the outside to the inside. In order to achieve the function of fixing the telescopic rod 15 and supporting the disinfection spray head, a fixing seat 15-4 for fixing the telescopic rod is provided at the lower end of the outermost telescopic unit, and a support block 15-5 for supporting the disinfection spray head is provided at the upper end of the innermost telescopic unit.

[0051] The specific structure of the telescopic unit includes an outer tube 15-1 and an inner tube 15-2 that can move and rotate axially in the outer tube 15-1. The outermost inner tube serves as the outer tube of the next telescopic unit. A locking assembly is provided at the lower end of the inner tube 15-2 for locking the inner tube 15-2 after it is extended to any height. A limiter 15-3 is provided at the upper end of the outer tube 15-1 for preventing the inner tube 15-2 from separating from the outer tube 15-1. A fixing seat 15-4 is provided at the lower end of the outermost outer tube 15-1, and a support block 15-5 is provided at the upper end of the innermost inner tube 15-2.

[0052] The specific structure of the locking assembly includes an extrusion block 15-6 and a rotating block 15-7 fixed at the lower end of the inner tube 15-2. A cylindrical first mating surface 15-7a is arranged on the outer side of the rotating block 15-7, and the axis of the first mating surface 15-7a does not coincide with the axis of the inner tube 15-2. A second mating surface 15-6a matching the first mating surface 15-7a is arranged on the inner side of the extrusion block 15-6. The extrusion block 15-6 is movably sleeved outside the first mating surface 15-7a, that is, the extrusion block is eccentrically sleeved outside the rotating block. In order to ensure that the extrusion block can achieve tension between the inner tube and the outer tube under the action of the rotating block, the sum of the maximum distance between the first mating surface 15-7a and the axis of the inner tube 15-2 and the maximum distance between the second mating surface 15-6a and the outer side of the extrusion block 15-6 is set to be greater than the inner radius of the outer tube 15-1.

[0053] When not locked, the end with the largest distance between the first mating surface 15-7a and the inner tube 15-2 and the end with the largest distance between the second mating surface 15-6a and the outer side surface of the extrusion block 15-6 are located on both sides of the axis of the inner tube 15-2, and a gap is left between the outer side surface of the extrusion block 15-6 and the inner side of the outer tube 15-1, so that the inner tube 15-2 can be extended or retracted. When the inner tube 15-2 is rotated to reach the locked state, the end with the largest distance between the first mating surface 15-7a and the inner tube 15-2 and the end with the largest distance between the second mating surface 15-6a and the outer side surface of the extrusion block 15-6 are both located on the same side of the axis of the inner tube 15-2, and the end with the largest distance between the second mating surface 15-6a and the outer side surface of the extrusion block 15-6 is interference fit with the inner side of the outer tube 15-1, so that the inner tube 15-2 and the outer tube 15-1 are locked. In this embodiment, the outer side surface of the rotating block and the outer side surface of the extruding block are both configured as cylindrical surfaces that coincide with the axis of the inner tube.

[0054] To ensure that the extrusion block can move together with the inner tube and the rotating block when they move together in the outer tube, the first mating surface 15-7a is set in the middle of the rotating block 15-7 and is formed by the inward depression of the outer surface of the rotating block 15-7. The diameter of the outer surface of the rotating block 15-7 at the upper and lower ends of the first mating surface 15-7a is larger than the diameter of the second mating surface 15-6a. To facilitate the installation of the extrusion block in the middle of the rotating block, an opening 15-6b is vertically arranged on the extrusion block 15-6, and the extrusion block is made of a material with a high elastic coefficient.

[0055] Since the first mating surface and the second mating surface are both set as cylindrical surfaces, locking can be achieved by rotating the inner tube clockwise or counterclockwise during rotation. However, in order to unify the locking direction of all inner tubes, a limiting protrusion 15-7b is set on the first mating surface 15-7a, and a limiting groove 15-6c is set on the extrusion block 15-6, which is misaligned with the opening 15-6b, and the central angle of the limiting groove 15-6c is less than 180°. At the same time, the limiting protrusion 15-7b extends into the limiting groove 15-6c, so that when the inner tube is rotated, locking can only be achieved when it is rotated in one direction. When rotating in the opposite direction, due to the cooperation between the limiting protrusion and the limiting groove, the extrusion block rotates synchronously, and locking cannot be achieved.

[0056] To facilitate installation, the extrusion block is set in an unlocked state, and the limiting groove 15-6c is set at the upper end of the extrusion block 15-6. At the same time, an indicating groove 15-6d is located below one end of the limiting groove 15-6c on the extrusion block 15-6 and is recessed from the inner side of the extrusion block 15-6 to the outside, wherein one end of the limiting groove refers to the end with the largest distance between the second mating surface and the outer side surface of the extrusion block. When the indicating groove 15-6d is aligned with the limiting protrusion 15-7b, the locking assembly is in an unlocked state.

[0057] To facilitate the installation of the rotating block at the lower end of the inner tube, a mounting protrusion 15-7c that can be inserted into the inner hole of the inner tube 15-2 is provided at the upper end of the rotating block 15-7, and a mounting through hole 15-7d perpendicular to the axis of the inner tube 15-2 is provided on the mounting protrusion 15-7c. To reduce the overall weight, a weight-reducing hole 15-7e is provided in the mounting protrusion 15-7c.

[0058] The limiting member 15-3 includes a limiting section 15-3a at the upper end and an insertion and installation section 15-3b at the lower end, the inner diameters of the limiting section and the insertion and installation section are both between the outer diameter of the inner tube and the outer diameter of the rotating block, wherein the outer diameter of the insertion and installation section 15-3b is smaller than the inner diameter of the outer tube 15-1, and a circle of clamping protrusions 15-3c with an outer diameter larger than the inner diameter of the outer tube 15-1 is provided at the lower end of the insertion and installation section 15-3b, and the lower end of the clamping protrusion 15-3c is provided as a cone with a larger upper part and a smaller lower part, and at the same time, a circle of clamping grooves 15-1a with a height not lower than the height of the clamping protrusion 15-3c is provided on the inner side of the outer tube 15-1, and the distance between the upper side surface of the clamping groove 15-1a and the upper side surface of the outer tube 15-1 is not greater than the distance between the upper side surface of the clamping protrusion 15-3c and the lower end of the limiting section 15-3a. In order to facilitate the insertion of the clamping protrusion into the outer tube, a plurality of vertical installation notches 15-3d are arranged at intervals on the clamping protrusion 15-3c.
