In addition, the water pump 32 is generally electrically connected with the control panel 9, and the working personnel can randomly switch the working state of the water pump 32 between opening and closing by operating the control panel 9, so as to quickly meet the current use demand.

[0070] In a specific application scenario, as shown in the accompanying drawings, Figure 1As shown, the inner walls on the left and right sides of the impurity removal chamber 11 are generally symmetrically provided with waste liquid discharge valves 14, the number of which is four, and the number and position of the waste liquid discharge device 5 correspond to those of the waste liquid discharge valves 14. Such a design can improve the speed of waste liquid discharge, thereby improving work efficiency to a certain extent. In addition, the waste liquid discharge valves 14 are generally electrically connected with the control panel 9. The operator can randomly switch the working state of the waste liquid discharge valves 14 between opening and closing by operating the control panel 9, thereby quickly meeting the current use demand. Of course, the user can make appropriate adjustments to the number and position of the waste liquid discharge valves 14 according to his own needs, and the corresponding content will not be described here.

[0071] In a specific application scenario, the waste liquid discharge device 5 is provided with a waste liquid guide groove 51, which is arranged on the side of the outer wall of the shell 1, and the position of the waste liquid guide groove 51 corresponds to that of the waste liquid discharge valve 14. When the waste liquid discharge valve 14 is opened, the waste liquid can flow out through the waste liquid guide groove 51. Such a design can provide a flow guide effect for the direction of the waste liquid, providing a prerequisite for easy collection and treatment of the waste liquid.

[0072] Further, the waste liquid discharge device 5 is also provided with a waste liquid collection container 52. In a specific application scenario, the discharge end of the waste liquid guide groove 51 is provided with a waste liquid collection container 52. Such a design can prevent waste liquid from overflowing and reduce the difficulty of waste liquid treatment.

[0073] In a specific application scenario, as shown in FIG. 4, the waste liquid discharge device 5 is provided with a waste liquid collection container 52, and the waste liquid guide groove 51 is arranged on the side of the waste liquid collection container 52. Such a design can prevent waste liquid from overflowing and reduce the difficulty of waste liquid treatment. Figure 1 As shown, the foregoing filter device 2 is provided with a first filter member 21, which is generally arranged in the middle of the impurity removal chamber 11. The first filter member 21 includes a first hinged piece 211, a first filter plate 212, and a first blocking assembly 213, etc. The first hinged piece 211 is arranged on the side of the inner wall of the impurity removal chamber 11, and the side of the first hinged piece 211 is provided with the first filter plate 212. As shown in FIG. 5, the first hinged piece 211 is provided with a first blocking assembly 213, and the first blocking assembly 213 is arranged on the side of the first hinged piece 211. Figure 1 , and Figure 2 and Figure 3As shown, the bottom of the first filter plate 212 has two generally symmetrically arranged first protrusions (not shown in the figure), and the two sides of the first protrusions have two generally symmetrically arranged first grooves (not shown in the figure), which are formed on the first filter plate 212; the bottom wall of the impurity removal chamber 11 is provided with a first blocking assembly 213. In use, the first hinge 211 can rotate the first filter plate 212 counterclockwise or clockwise, and the angle formed by the first filter plate 212 moving from the initial position to the end position is approximately 90°, and the first filter plate 212 will not collide with the spraying component 34 of the cleaning device 3; in two cases, the first hinge 211 will stop rotating: first, the first filter plate 212 moves to the first blocking assembly 213; second, the top of the first filter plate 212 is generally parallel to the top of the housing 1; this design can reduce the workload of the first hinge 211, thereby extending the service life of this embodiment to a certain extent. In addition, the first hinge 211 is generally electrically connected to a control panel 9. By operating the control panel 9, the operator can freely control the rotation state of the first hinge 211, that is, rotate it from the initial position to the end position and from the end position to the initial position, thereby quickly meeting the current usage requirements.

[0074] Furthermore, as shown in the appendix Figure 3 As shown, the first blocking component 213 mainly includes a first protrusion 2131 and a first blocking block 2132; the bottom end of the first protrusion 2131 is connected to the bottom wall of the impurity removal chamber 11, and the first protrusion 2131 is adapted to the first protrusion; the first blocking blocks 2132 are arranged symmetrically on both sides of the first protrusion 2131, and the first blocking blocks 2132 are adapted to the first groove. This design can further prevent the first filter plate 212 from leaving the preset movement space, and at the same time, the first blocking component 213 can offset part of the impact force generated by the cleaning device 3.

[0075] Furthermore, as shown in the appendix Figure 1 As shown, a second filter component 22 is disposed on the front side of the first filter component 21. The second filter component 22 is located inside the impurity removal chamber 11, and there is a space for movement between the second filter component 22 and the first filter component 21, meaning that the movements of the first filter component 21 and the second filter component 22 will not interfere with each other. The second filter component 22 includes components such as a second hinge 221, a second filter plate 222, and a second blocking assembly 223. The second hinge 221 is disposed on the side of the inner wall of the impurity removal chamber 11, and the second filter plate 222 is disposed on the side of the second hinge 221. (See attached diagram.) Figure 1 Appendix Figure 2 and appendix Figure 3As shown, the second filter plate 222 has two symmetrically arranged second protrusions on both sides of its bottom end, and two symmetrically arranged second grooves on both sides of the second protrusions. The second grooves are formed on the second filter plate 222. The bottom wall of the impurity removal chamber 11 is provided with a second blocking assembly 223. In use, the second hinge 221 can rotate the second filter plate 222 clockwise or counterclockwise. The angle formed by the second filter plate 222 moving from the initial position to the end position is approximately 90°, and the second filter plate 222 will not collide with the spraying component 34 of the cleaning device 3. In two cases, the second hinge 221 will stop rotating: first, the second filter plate 222 moves to the second blocking assembly 223; second, the top of the second filter plate 222 is approximately parallel to the top of the housing 1. This design can reduce the workload of the second hinge 221, thereby extending the service life of this embodiment to a certain extent. In addition, the second hinge 221 is generally electrically connected to a control panel 9. By operating the control panel 9, the operator can freely control the rotation state of the second hinge 221, that is, rotate it from the initial position to the end position and from the end position to the initial position, thereby quickly meeting the current usage requirements.

[0076] Furthermore, as shown in the appendix Figure 3 As shown, the second blocking component 223 mainly includes a second protrusion 2231 and a second blocking block 2232; the bottom end of the second protrusion 2231 is connected to the bottom wall of the impurity removal chamber 11, and the second protrusion 2231 is adapted to the second protrusion; the second blocking blocks 2232 are arranged symmetrically on both sides of the second protrusion 2231, and the second blocking blocks 2232 are adapted to the second groove. This design can further prevent the second filter plate 222 from leaving the preset movement space, and at the same time, the second blocking component 223 can offset part of the impact force generated by the cleaning device 3.

[0077] It should be noted that the mesh count of the second filter plate 222 is greater than that of the first filter plate 212. If the current impurity removal requirements are not high, the second filter plate 222 can be rotated to a position parallel to the top of the housing 1, i.e., the end position of the second filter plate 222. If the current impurity removal requirements are high, the first filter plate 212 and the second filter plate 222 can be lowered simultaneously, so that both the first filter plate 212 and the second filter plate 222 are in their initial positions, as shown in the attached diagram. Figure 1As shown; furthermore, when the operator needs to clean the filter device 2, the first filter plate 212 and the second filter plate 222 should be placed alternately. That is, when cleaning the first filter plate 212, place it in the initial position and the second filter plate 222 in the final position; when cleaning the second filter plate 222, place it in the initial position and the first filter plate 212 in the final position. This design can improve the cleaning effect of the filter device 2. Of course, users can adjust the number of filter components and the mesh size of the filter plates according to their own needs, as long as their purpose is achieved.

[0078] In a specific application scenario, as shown in the appendix Figure 4 As shown, the sealing device 6 mainly includes a cover plate 61 and a handle 62; the cover plate 61 is disposed at the top of the housing 1 along its own length direction, and the handles 62 are arranged symmetrically on both sides of the top of the cover plate 61. If the staff wants to check the condition of the cleaning chamber 11, they can hook the handle 62 with a crane; then, start the crane to remove the cover plate 61, as shown in the attached figure. Figure 5 As shown, this design can prevent cleaning water from splashing out from the top of the housing 1, and also reduce the pollution of gasoline by the external environment. Therefore, the sealing device 6 cannot be removed from the top of the housing 1 when performing the gasoline impurity removal process and the cleaning process of the filter device 2.

[0079] Furthermore, a sealing ring (not shown in the figure) is provided at the position where the bottom of the cover plate 61 contacts the top of the housing 1. This design can prevent cleaning water from overflowing from the gap between the cover plate 61 and the housing 1.

[0080] To achieve intelligent operation in this embodiment, the housing 1 is provided with the aforementioned control panel 9. In a specific application scenario, as shown in the attached... Figure 2 As shown, the control panel 9 is located on the left side of the housing 1. Of course, users can adjust the position of the control panel 9 according to their needs, and the relevant details will not be elaborated here.

In addition to the components in the aforementioned embodiment 1, it also includes a monitoring device 4. The operator can check the cleaning status of the filter device 2 without opening the aforementioned sealing device 6, which improves the user experience of this embodiment and thus enhances the working performance of the aforementioned embodiment 1.

[0083] In a specific application scenario, as shown in the appendix Figure 2As shown, the monitoring devices 4 are arranged symmetrically on the front and back sides of the inner wall of the impurity removal chamber 11, and the number of the monitoring devices 4 is four; generally, the position of the monitoring devices 4 is higher than the spraying member 34 in the embodiment 1, and such design can reduce the negative influence of the cleaning water on the monitoring devices 4; wherein, the monitoring devices 4 are generally electrically connected with the control panel 9 in the embodiment 1, and the image information recorded by the monitoring devices 4 can be displayed on the screen of the control panel 9, and such design can save the step of moving away the sealing device 6, thereby improving the work efficiency. Of course, the user can make appropriate adjustment on the number and position of the monitoring devices 4 according to the own needs, and the corresponding contents are not described here.

[0084] Further, the monitoring devices 4 are micro cameras; wherein, the micro cameras have the advantages of small size and convenient installation.
