[0035] The utility model proposes a testing device for a dirty sensor assembly of a cleaning device, referring to Figure 1 The dirt sensor assembly 200 includes a sewage box and a dirt sensor. The dirt sensor is arranged on the sewage box. The sewage box includes an inlet and an outlet. The test equipment includes:

[0036] The base 100 is used to carry the dirt sensor assembly;

[0037] A water tank, used for containing the test liquid and connected to the inlet and outlet of the sewage box through a water pipe;

[0038] A water pump, one end of which is connected to the water tank and the other end is connected to the sewage box, used to push the test liquid into the sewage box;

[0039] The gas source is connected to the sewage box and is used to release high-pressure gas to push the test liquid out of the sewage box;

[0040] The upper computer is electrically connected to the dirt sensor, the water pump and the air source, and is used to control the water pump and the air source to be turned on or off, and to judge whether the dirt sensor component is qualified according to the dirt value measured by the dirt sensor.

[0041] The main function of the base 100 is to provide a stable support platform to ensure that the dirt sensor assembly can be stably placed on it for testing. The top of the base 100 is usually a solid planar structure, and the size of the base 100 can be adjusted as needed to place different types of dirt sensor assemblies 200. A clamp can be set on the top of the base 100 to fix the dirt sensor assembly 200. At the same time, since some test liquid will still remain in the sewage box after the test is completed, it is easy for the test liquid to flow onto the base 100 when the sewage box is taken out and placed. Therefore, the interior of the base 100 can be set as a cavity, and a water receiving device can be placed in the cavity. At the same time, grooves and through holes are set on the top of the base 100 to guide the test liquid to flow in, so as to prevent the test liquid from flowing to other workstations or the ground and affecting the normal work of the staff. Preferably, the base 100 is made of a plastic or alloy with high pressure resistance and anti-aging properties, and the top of the base 100 is anti-slip treated, which can effectively prevent the dirt sensor assembly 200 to be tested from sliding; and height-adjustable foot spikes can be installed on the bottom edge of the base 100, so that the base 100 can be set on an uneven ground, thereby improving its applicability.

[0042] The dirt sensor assembly 200 is an assembly comprising a sewage box and a dirt sensor mounted on the box. The dirt sensor is typically a photoelectric sensor and consists of two parts, mounted on two opposing outer surfaces of the box. The first part emits light, acting as a light emitter, while the second part receives the light emitted by the first part, acting as a light receiver. The dirt sensor determines the degree of water contamination by detecting changes in light after it passes through the sewage. For example, the dirt sensor detects contamination of test liquid passing through the sewage box. Under normal circumstances, if the test liquid in the sewage box is relatively dirty, the dirt sensor will detect a higher contamination value. If the test liquid in the sewage box is relatively clean, the dirt sensor will detect a lower contamination value. The dirt sensor assembly 200 is typically mounted on the base 100 using an appropriate fixing device to ensure that the dirt sensor under test does not move during testing.

[0043] The water tank is a container for holding the test liquid. This test liquid is a standard test liquid, that is, it has a specific contamination value (standard contamination value). During the test, the water tank is connected to the inlet and outlet of the sewage box via water pipes. A water pump draws the test liquid from the water tank and flows it through the sewage box, through the sewage, and finally back to the water tank, recycling the test liquid. During this process, the contamination sensor measures the test liquid flowing through the sewage box to obtain the contamination value. The air source is a device that provides high-pressure gas and is connected to the sewage box. After the test is completed, the high-pressure gas is used to drain the test liquid from the sewage box and water pipes, or through the water pipes and back to the water tank. It is understood that the test liquid in the water tank can be replaced as needed, or multiple water tanks can be used, each storing test liquid with different levels of contamination (or different colors), to obtain multiple sets of test data and improve the accuracy of the test results.

[0044] The host computer is a computer device electrically connected to the dirt sensor, water pump, and air source, and is used to control and monitor the testing process. It is responsible for controlling the opening and closing of the water pump and air source to automate the test. It also receives data measured by the dirt sensor and analyzes and determines whether the dirt sensor assembly 200 is qualified. The judgment process involves comparing the dirt value measured by the dirt sensor assembly 200 with the dirt standard value corresponding to the test liquid in the water tank. If the difference is significant, the dirt sensor assembly 200 fails; otherwise, it passes. Of course, personnel can also perform independent data analysis and judgment, with the host computer serving as the data collector and organizer.

[0045] The actual testing process is as follows:

[0046] First, a dirtiness standard value of the test liquid in the water tank is determined. The dirtiness standard value is measured by a standard dirtiness sensor assembly 200 .

[0047] Subsequently, the dirt sensor assembly 200 to be tested is placed on the base 100, and the test liquid in the water tank is pushed into the sewage box by a water pump; at this time, the dirt sensor collects the dirt value of the test liquid entering the sewage box; after the test is completed, the dirt sensor uploads the measured dirt value to the host computer, and the host computer compares the dirt value with the standard dirt value stored in itself. If the difference is large (exceeds the predetermined value), the dirt sensor assembly 200 is judged to be unqualified, otherwise it is qualified.

[0048] Finally, after the test is completed, the test liquid in the sewage box is pressed out by using an air source, thereby emptying the sewage box, making it easier for the tester to remove the dirt sensor assembly 200 from the base.

[0049] The above method can be used to test the dirt sensor assembly 200 under test, accurately testing and simulating it to ensure its normal operation and performance. The host computer greatly simplifies the testing process and reduces the workload of testers. Its data analysis and judgment functions can help determine whether the dirt sensor assembly 200 meets the requirements, thereby improving the factory quality of the cleaning equipment and effectively reducing the rework rate.

[0050] like Figure 1 As shown, in some embodiments, the testing device further includes:

[0051] A water inlet connector 300, one end of which is movably connected to the inlet and the other end is connected to the water pipe; and / or,

[0052] The water outlet joint 400 has one end movably connected to the outlet and the other end connected to the water pipe.

[0053] The water inlet connector 300 is positioned between the sewage box inlet and the water pipe, typically having a tubular structure. Interoperable clips or threads can be provided on the water inlet connector 300 and the sewage box inlet, significantly enhancing the seal of the connection. Preferably, one end of the water inlet connector 300 is connected to the sewage box inlet in a flexible manner, allowing the water inlet connector to rotate or move, making it easier to align with the sewage box inlet and replace the dirt sensor assembly 200 that needs testing. The water outlet connector 400 is similar to the water inlet connector and will not be described in detail here.

[0054] like Figure 1 As shown, in some embodiments, the water inlet connector 300 is connected to a movable cylinder 110, which is disposed on the base 100 and electrically connected to the host computer for controlling the water inlet connector 300 to connect or disconnect the sewage box, and / or,

[0055] The water outlet joint 400 is connected to a movable cylinder 110 . The movable cylinder 110 is provided on the base 100 and is electrically connected to a host computer for controlling the water outlet joint 400 to connect or disconnect the sewage box.

[0056] The movable cylinder 110 is a pneumatic device. The water outlet connector 400 or the water inlet connector 300 is connected to the movable cylinder 110 and can be driven by the movable cylinder 110 to perform reciprocating motion.

[0057] In this embodiment, the sewage box's inlet faces upward, and the movable cylinder 110 is positioned perpendicular to the box, driving the water inlet connector 300 up and down, thereby connecting and disconnecting the sewage box. The sewage box's outlet faces rightward, and the movable cylinder 110 is positioned parallel to the box, driving the water outlet connector 400 left and right. As will be appreciated, since different sewage boxes have different outlets and inlets, the installation positions of the water outlet connector 400 and the water inlet connector 300 also vary, and the position of the movable cylinder 110 must be adjusted based on actual conditions.

[0058] In some embodiments, the moving cylinder 110 connected to the water inlet connector 300 and the moving cylinder 110 connected to the water outlet connector 400 may be the same, especially when the inlet and outlet of the sewage box face the same direction.

[0059] In some embodiments, the movable cylinder 110 connected to the water inlet connector 300 and the movable cylinder 110 connected to the water outlet connector 400 may be two independently provided movable cylinders 110 , especially when the inlet and outlet of the sewage box face different directions.

[0060] In some embodiments, a sealing ring is provided at the interface where the water inlet connector 300 and / or the water outlet connector 400 is connected to the sewage box.

[0061] The sealing ring is generally made of a corrosion-resistant, wear-resistant, soft and durable material, such as rubber (such as silicone rubber, nitrile rubber), polymer (such as polytetrafluoroethylene), or special sealing materials, depending on the properties of the test liquid in the water tank. The sealing ring is usually in the shape of a ring to adapt to the external shape of the connection interface of the water inlet connector 300 and / or the water outlet connector 400. For example, the outlet of the sewage box is made into a protruding cylindrical shape so that the outlet can be just accommodated in the outlet valve, and then grooves are provided at corresponding positions on the outer wall of the outlet of the sewage box and the inner wall of the outlet valve to accommodate the sealing ring, which can enhance the sealing performance of the connection and ensure that no test liquid flows out. Similarly, the sealing ring can also be other shapes that can fit the connection between the water inlet connector or the water outlet connector and the sewage box, as long as it is ensured to have good sealing properties.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments, a fixing assembly 500 is provided on the base 100 , and the fixing assembly 500 is used to fix the dirt sensor assembly 200 .

[0063] The fixing assembly 500 is used to secure the dirt sensor assembly 200 to the base 100, ensuring that the dirt sensor assembly 200 remains stable during testing or when connecting the water inlet connector 300 and the water outlet connector 400. The fixing assembly 500 can be secured to the dirt sensor assembly 200 in a variety of ways, such as by snap-fitting. A groove or snap-fitting notch is provided on the base 100, and a corresponding protrusion or snap is provided on the sewage box. Inserting the sewage box into the base 100 or snapping the snap onto the snap securely secures the dirt sensor assembly 200 to the base 100, facilitating quick assembly and disassembly. Alternatively, a threaded fastening method can be employed. Matching threads are provided on the base 100 and the dirt sensor assembly 200, and the dirt sensor assembly 200 is secured to the base 100 by rotating it. This provides a more secure connection than a snap-fit ​​connection and significantly reduces the impact of vibration caused by the test liquid flowing through the sewage box on the connection. Magnetic components can also be installed on the base 100 and the sewage box to allow them to attract each other and maintain a fixed position, which is very simple to operate. Different fixing methods can be used for sewage boxes of different sizes and shapes. In this embodiment, a clamping method is preferred. A clamping device is provided on the base 100, and the sewage box is clamped manually or automatically to fix the dirt sensor assembly 200 to the base 100.

[0064] like Figure 2 As shown, in some embodiments, the fixing assembly 500 includes:

[0065] The bracket 510 is provided on the base 100 and is used to carry the dirt sensor assembly 200;

[0066] The bracket 510 generally has an appropriate shape and size to facilitate placement of the dirt sensor assembly 200. For example, a groove may be provided on the upper surface of the bracket 510 to accommodate the dirt sensor assembly 200, or the upper surface of the bracket 510 may be flat and anti-slip to support the dirt sensor assembly 200. Preferably, a sensor may be provided on the bracket 510 to detect whether the dirt sensor assembly is properly installed.

[0067] like Figure 2 As shown, in some embodiments, the fixing assembly 500 further includes:

[0068] The pressing module includes a transmission member 520 and an abutment member 530 fixedly connected to the transmission member 520;

[0069] The transmission member 520 drives the abutting member 530 to rise or fall. When the transmission member 520 falls, the abutting member 530 presses the sewage box onto the bracket 510 .

[0070] The sewage box of the dirt sensor assembly 200 is relatively large. Therefore, for convenience, a pressing module is used to press the sewage box against the bracket 510, ensuring that the sewage box does not move when the test liquid flows through it, thereby ensuring that the entire dirt sensor assembly 200 does not move. The transmission member 520 is part of the pressing module and can be controlled manually or by an additional electric, pneumatic, or hydraulic mechanism to achieve up and down movement. This simultaneously drives the abutment member 530 to rise or fall, thereby pressing or releasing the dirt sensor assembly 200. When the transmission member 520 descends, the abutment member 530 contacts the sewage box and applies pressure, pressing the sewage box against the bracket 510 and preventing it from accidentally moving or shaking. The arrangement of the transmission member 520 and the abutment member 530 makes the pressing effect of the pressing module controllable, allowing the dirt sensor assembly 200 to be pressed or released as needed, making it easier for personnel to remove and place the dirt sensor assembly 200.

[0071] like Figure 2 As shown, in some embodiments, a plurality of limiting posts 511 and / or a plurality of limiting blocks 512 are provided on the top of the bracket 510. The limiting posts 511 are provided to fit the contour of the sewage box, and the limiting blocks 512 are provided to correspond to the bottom grooves of the sewage box.

[0072] Among them, several limiting posts 511 limit the sewage box to a certain range to facilitate accurate testing, while the limiting blocks 512 correspond to the bottom groove of the sewage box. The cooperation between the two ensures that the sewage box is accurately positioned and maintained in the appropriate position. It is understandable that the number and shape of limiting posts 511 and limiting blocks 512 corresponding to different models and types of sewage boxes are also different, and can be set according to actual conditions. Preferably, the limiting posts 511, limiting blocks 512 and bracket 510 are made of one-piece molding. The one-piece design is generally more stable because the limiting posts 511 and limiting blocks 512 are integrated with the bracket 510, reducing the possibility of movement or loosening between the two. It can withstand the vibration and impact that may be caused by the dirt sensor assembly 200 during testing and is more durable, which helps ensure that the dirt sensor assembly 200 maintains the accurate position and direction during testing. In addition, the one-piece design avoids the assembly process, saving time and labor costs.

[0073] Preferably, in this embodiment, since the sewage box is in the shape of a rectangular parallelepiped as a whole, there are four limiting columns 511, which are symmetrically arranged in pairs on the top of the bracket 510, and there are two limiting blocks 512, corresponding to the two grooves at the bottom of the sewage box, to complete the fixation of the sewage box.

[0074] like Figure 1 and Figure 2As shown, in some embodiments, the transmission member 520 includes a mounting frame 521, a handle 522 and a slide rod 523. The mounting frame 521 is set on the base 100, the handle 522 is rotatably connected to the mounting frame 521, the slide rod 523 is slidably connected to the mounting frame 521, the handle 522 is rotatably connected to one end of the slide rod 523, and the abutment 530 is set at the other end of the slide rod 523; when the handle 522 is rotated, the slide rod 523 drives the abutment 530 to slide up and down.

[0075] The mounting bracket 521 is part of the transmission member 520. It is mounted on the base 100 and provides support and positioning for the handle 522 and slide bar 523, ensuring they can execute correct movements. The slide bar 523 is a long rod that is slidably connected to the mounting bracket 521. The lower end of the slide bar 523 is connected to an abutment 530, which contacts and applies pressure to the sewage box, thereby securing the dirt sensor assembly 200 to the bracket 510. The connection between the slide bar 523 and the mounting bracket 521 can be achieved in various ways, such as by providing a slide rail or channel on the mounting bracket 521 within which the slide bar 523 can slide to achieve vertical movement. The handle 522 is used to drive the slide bar 523 up and down. Because the handle 522 is connected to the mounting bracket 521 through a rotational connection, the handle 522 can rotate about the connection. Therefore, when the handle 522 rotates, the handle 522 transfers the motion to the slide bar 523, thereby driving the slide bar 523 up and down. It is worth mentioning that the sliding connection method between the handle 522 and the slide bar 523 can be selected as needed, such as a pin connection. Preferably, in this embodiment, the slide bar 523 near the handle 522 is provided with two connecting posts protruding, and the end of the handle 522 near the slide bar 523 is divided into two curved plates with holes. The two connecting posts pass through the holes of the two curved plates respectively to achieve a movable connection between the handle 522 and the slide bar 523. Preferably, the handle end of the handle 522 can be provided with an anti-slip sleeve or anti-slip texture to increase friction and facilitate use by testers.

[0076] It is worth mentioning that the movement directions of the handle 522 and the slide bar 523 can be the same or opposite. For example, when the handle 522 is directly connected to the mounting frame, pressing down one end of the handle 522 will cause the slide bar 523 connected to the other end of the handle 522 to rise, driving the abutment 530 to rise. At this time, the movement directions of the handle 522 and the slide bar 523 are opposite. Figure 2 As shown, the handle 522 is connected to the mounting frame 521 through a connecting plate, wherein the two ends of the connecting plate are rotatably connected to the mounting frame 521 and the handle 522 respectively. At this time, when one end of the handle 522 is pressed down, the slide bar 523 will also drop down, so that the movement direction of the handle 522 and the slide bar 523 are the same, reducing the possibility of misoperation by the staff.

[0077] like Figure 1As shown, in some embodiments, the upper surface of the bracket 510 is inclined, and the height of the bracket 510 increases from the end close to the water inlet connector 300 to the end close to the water outlet connector 400 .

[0078] On the one hand, the tilted upper surface of the bracket 510 ensures that the test liquid in the sewage box naturally flows toward one end of the water inlet connector 300. This helps the test liquid drain out of the sewage box through the inlet after the test is completed, ensuring that the test liquid in the sewage box does not remain after the test, thereby reducing the need for cleaning and maintenance. On the other hand, the tilt angle is determined based on the actual installation angle of the dirt sensor assembly 200 in the cleaning equipment, ensuring that the test environment is consistent with the actual operating environment, thereby improving the accuracy of the test results.

[0079] like Figure 1 and Figure 2 As shown, in some embodiments, the lower surface of the abutment member 530 is parallel to the upper surface of the bracket 510 .

[0080] Since the upper surface of the bracket 510 is tilted, when the dirt sensor assembly 200 is placed on the upper surface of the bracket 510, the upper surface of the sewage box is usually also tilted. In order to make the pressing more snug, the lower surface of the abutment 530 is set parallel to the upper surface of the bracket 510, so that the pressure when the abutment 530 presses the sewage box is evenly distributed, avoiding deformation of the sewage box, thereby improving the accuracy of the test.

[0081] The utility model uses a water pipe to connect the water tank and the dirt sensor assembly 200, and under the action of a water pump, the test liquid in the water tank flows through the sewage box in the dirt sensor assembly 200, thereby obtaining the dirtiness value of the test liquid by the dirt sensor of the dirt sensor assembly 200, and the upper computer or staff makes a judgment, thereby simply and conveniently realizing the test of the dirt sensor assembly 200, and ensuring the quality of the cleaning equipment when it leaves the factory.

[0082] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
