DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0032] Reference Figure 1-6A high-pressure steam cleaning device for trash cans includes a cleaning box 1 with an inlet and outlet 13 on one side that matches the trash can. An outer cleaning mechanism 2 is located at the upper portion of the inner chamber of the cleaning box 1, and an inner cleaning mechanism 3 is located at the lower portion. A sewage discharge mechanism 4 is located below the inner cleaning mechanism 3. The outer cleaning mechanism 2 cleans the outside of the trash can, while the inner cleaning mechanism 3 cleans the inside of the trash can. The dirt removed by the cleaning falls into the sewage discharge mechanism 4, which is collected and discharged.
[0033] The outer cleaning mechanism 2 and the inner cleaning mechanism 3 are both provided with two layers of wind knife assemblies 21 and corresponding lifting assemblies for driving the wind knife assemblies 21 to rise and fall. The wind knife assemblies 21 include multiple wind knifes 211 and corresponding connecting pipes 212. The multiple wind knifes 211 in the outer cleaning mechanism 2 are provided corresponding to the outer wall of the trash can, blowing air inward to clean the outer wall of the trash can; the multiple wind knifes 211 in the inner cleaning mechanism 3 are provided corresponding to the inner wall of the trash can, blowing air outward to clean the inner wall of the trash can. In this technical solution, four wind knifes 211 are provided in one layer of wind knife assembly 21, which are respectively provided corresponding to each side wall of the trash can to ensure the cleaning effect of the trash can. During cleaning, the wind knife assembly 21 is driven up and down by the lifting assembly to comprehensively clean each side wall of the trash can.
[0034] The connecting pipe 212 of one layer of the air knife assembly 21 is connected to the steam supply device and the compressed air supply device, and the connecting pipe 212 of the other layer is connected to the coating agent supply device, respectively used for cleaning and coating the trash can. The steam supply device delivers steam to the air knife 211. A high-pressure blower vortex air pump can also be added between the steam supply device and the connecting pipe 212 to ensure steam pressure. The air knife sends high-pressure steam to blow the side walls of the trash can, stripping away dirt and coatings attached to the surface of the trash can, ensuring the complete cleaning of the trash can surface and improving the cleaning ability of the high-pressure steam. To prevent the trash can from deforming due to heat, the steam temperature is controlled at 60-80°C.
[0035] Based on the above technical solution, when using this equipment to clean a trash can, use an automatic loading device such as a trash can clamping device, a flipping device, or use manual loading to invert the trash can and send it into the cleaning equipment, and keep the trash can in the position between the outer cleaning mechanism 2 and the inner cleaning mechanism 3. First, steam is sent out through the wind knife assembly 21 to blow the trash can, and the lifting assembly drives the wind knife assembly 21 to move vertically on both sides of the inside and outside of the trash can for comprehensive blowing, so as to peel off and remove the dirt and film adhering to the surface of the trash can.
[0036] After the purging is completed, the steam supply is switched to compressed air supply, and reciprocating purging is performed again. The compressed air is used to blow away the residual water vapor on both sides of the trash can, which facilitates the subsequent laminating process and ensures the laminating effect.
[0037] After the interior and exterior of the trash can are purged and water is removed, the air knife assembly 21 switches to another layer. Air knife 211 delivers atomized coating agent, spraying it onto both sides of the trash can to reduce the adhesion of dirt to the trash can. A suitable amount of detergent can also be added to the coating agent to enhance the decontamination effect during steam decontamination. To ensure the coating effect, a silicone emulsion is used as the coating agent.
[0038] To facilitate observation while cleaning the trash can, an observation window 11 is embedded in the side wall of the cleaning box 1. To enhance the overall strength of the cleaning box 1, a frame 12 is provided inside the cleaning box 1, ensuring both strength and lightweight. To facilitate entry and exit of the trash can, a guide plate 131 is provided at the entrance and exit 13 to guide the entry and exit of the trash can, ensuring efficient entry and exit of the trash can.
[0039] In this technical solution, if Figure 1-6 As shown, a mounting bracket 22 for securing the air blades 211 is provided between the two layers of air knife assemblies 21 and is connected to a lifting assembly. The lifting assembly includes linear motors 23 vertically positioned on the front and rear sides of the air knife assemblies 21, and an electric strut 33 vertically mounted on the bottom of the cleaning box 1. The slide on the linear motor 23 is connected to the mounting bracket 22 in the outer cleaning mechanism 2, and the telescopic end of the electric strut 33 is fixedly connected to the mounting bracket 22 in the inner cleaning mechanism 3. The linear motor 23 drives the outer cleaning mechanism 2 up and down to clean the outside of the trash can, while the electric strut 33 drives the inner cleaning mechanism 3 up and down to clean and coat the inside of the trash can, ensuring effective cleaning and coating of both the inside and outside of the trash can.
[0040] In this technical solution, if Figure 1-3 As shown, slide rods 232 are vertically mounted on either side of the electric linear motor 23. Slide sleeves 231 are slidably mounted on the slide rods 232. Slide sleeves 231 are fixedly mounted on the outside of the mounting bracket 22 in the outer cleaning mechanism 2. The mounting bracket 22 is equipped with multiple temperature sensors to facilitate steam temperature monitoring and maintain a stable steam temperature to prevent deformation of the trash can due to excessive steam temperature. The arrangement of the slide rods 232 and the slide sleeves 231 enhances the stability of the outer cleaning mechanism 2 and ensures the effective lifting and lowering movement of the outer cleaning mechanism 2.
[0041] In this technical solution, if Figure 1-5As shown, the outer cleaning mechanism 2 further includes two first lid cleaning air knives 24 provided corresponding to the bin lid and corresponding first branch pipes 241. The two first branch pipes 241 are respectively connected to the two layers of connecting pipes 212 of the outer cleaning mechanism 2. Due to the design of the first lid cleaning air knives 24, they move up and down with the outer cleaning mechanism 2. When they move to the top of the bin lid, the first lid cleaning air knives 24 clean and coat the outer side of the bin lid, ensuring that the trash can is thoroughly cleaned.
[0042] In this technical solution, if Figure 1-6 As shown, the inner cleaning mechanism 3 is further provided with a second bucket cover cleaning air knife 34 and a corresponding second branch pipe 341. The two second branch pipes 341 are respectively connected to the two layers of connecting pipes 212 of the inner cleaning mechanism 3. Through the design of the second bucket cover cleaning air knife 34, the bucket cover is cleaned and coated from the bottom of the bucket cover. The first bucket cover cleaning air knife 24 and the second bucket cover cleaning air knife 34 are used to synchronously steam purge the inside and outside of the bucket cover, thereby preventing the bucket cover from turning over due to steam purge, and ensuring stable cleaning of the bucket cover.
[0043] In this technical solution, if Figure 1-3 As shown, the sewage discharge mechanism 4 includes a collection hopper 41 provided at the bottom of the cleaning box 1, a sewage discharge pipe 411 connected to the discharge end of the collection hopper 41, and a vacuum negative pressure sewage discharge pump 42 provided in the cleaning box 1. The sewage and dirt in the collection hopper 41 are discharged by the vacuum negative pressure sewage discharge pump 42, realizing vacuum negative pressure self-absorption sewage collection and discharge, ensuring the sewage discharge effect of strongly adherent dirt.
[0044] In this technical solution, if Figure 1-3 As shown, a plurality of supporting rods 5 are provided horizontally at the lower end of the corresponding bucket cover in the cleaning box 1. The bucket cover is supported to ensure that the bucket cover is opened and in a suitable position, thereby ensuring comprehensive cleaning and laminating effect on the trash can and the bucket cover.
[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
