[0023] Hereinafter, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some, not all, of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0024] In addition, the present disclosure may repeat reference numerals and / or reference characters in different examples.

In addition, the present disclosure provides examples of various specific processes and materials, but those skilled in the art can recognize the application of other processes and / or the use of other materials.

[0025] Hereinafter, the present disclosure will be described with reference to specific embodiments in conjunction with the drawings.

[0026] Embodiments of the present disclosure provide a wastewater detection device. As shown in Figures 1 to 8, the wastewater detection device includes a housing 100, a detection pipe 200, and a detection assembly 300. A housing chamber is provided inside the housing 100, and the housing 100 is provided with a water inlet 111, a drain outlet 112, and a wiring hole 113 that communicate with the housing chamber. The detection pipe 200 is installed inside the housing chamber, and both ends of the detection pipe 200 communicate with the water inlet 111 and the drain outlet 112, respectively. The detection assembly 300 is installed inside the housing chamber and includes a transmitter 310, a receiver 320, a circuit board 330 connected to the transmitter 310 and the receiver 320, and a wire harness connected to the circuit board 330. The transmitter 310 and the receiver 320 are installed opposite each other on both sides of the detection pipe 200. The wire harness extends to the outside of the housing 100 through the wiring hole 113.

[0027] In the wastewater detection device of this disclosure, as shown in Figures 1 to 8, the wastewater detection device is connected in series to the wastewater pipeline via the water inlet 111 and wastewater inlet on the housing 100, that is, wastewater in the wastewater pipeline can be detected. The wastewater detection device is easy to install and apply in cleaning equipment. At the same time, the wastewater detection device seals the detection tube 200 and detection assembly 300 in a containment chamber via the housing 100, creating a stable and clean detection environment in the containment chamber, preventing dust and water vapor from entering the containment chamber and contaminating the detection tube 200 or interfering with the detection signal of the detection assembly 300, thereby ensuring the accuracy and stability of detection by the wastewater detection device. Furthermore, the detection tube 200 and detection assembly 300 are protected, further preventing damage to the detection tube 200 and detection assembly 300, and extending the service life of the wastewater detection device.

[0028] In some embodiments, as shown in Figures 1 to 5, the water inlet 111 and wastewater inlet on the housing 100 may be connected in series within the wastewater pipeline, so that wastewater can enter the detection pipe 200 inside the containment chamber via the water inlet 111. At the same time, the transmitter 310 and receiver 320 of the detection assembly 300 are positioned opposite each other on both sides of the detection pipe 200 so as to detect the wastewater flowing through the detection pipe 200 and obtain the cleanliness of the wastewater.

[0029] In some embodiments, as shown in Figures 3 to 5, the detection assembly 300 is a detection assembly 300 that can be used to detect parameters such as the turbidity of wastewater, such as an optical detection assembly 300, an electrical signal detection assembly 300, or an ultrasonic detection assembly 300.

[0030] As one selectable embodiment, as shown in Figures 1 to 5, the detection assembly 300 is a photodetection assembly 300. Translucent surfaces 210 are provided on at least two opposing sides of the detection tube 200. The transmitter 310 and receiver 320 correspond to the translucent surfaces 210.

[0031] In some embodiments, as shown in Figures 1 to 5, a light-transmitting surface 210 is provided on at least two opposing sides of the detection tube 200, and the transmitter 310 and receiver 320 are installed opposite each other on both sides of the detection tube 200, with the transmitter 310 and receiver 320 corresponding to the light-transmitting surfaces 210, respectively. At the same time, the detection assembly 300 is a photodetection assembly 300, meaning that the transmitter 310 transmits (emits) detection light rays, and the receiver 320 is used to receive (receive) the detection light rays after they have passed through the detection tube 200. When the detection light rays pass through the detection tube 200, a portion of the detection light rays is scattered by the influence of the wastewater inside the detection tube 200, changing the propagation direction, and the receiver 320 can receive only a portion of the detection light rays transmitted from the transmitter 310. The detection assembly 300 can obtain the amount of foreign matter in the wastewater inside the detection tube 200 based on the amount of light loss received by the receiver 320, and determine the cleanliness of the wastewater.

[0032] In some embodiments, the detection assembly 300 may be provided with at least two sets of transmitters 310 and receivers 320, where one set of transmitters 310 and receivers 320 is used for detection and the other set of transmitters 310 and receivers 320 is used for blank reference.

[0033] The detection assembly 300 is a photodetection assembly 300, and the light-transmitting surface 210 of the detection tube 200 is highly susceptible to environmental influences. In the embodiments of the present disclosure, by installing the detection tube 200 and the detection assembly 300 in a sealed containment chamber, it is possible to prevent dust, water vapor, etc. from entering the containment chamber and contaminating the detection tube 200 or interfering with the detection assembly 300, thereby improving the detection accuracy of the wastewater detection device.

[0034] As one possible embodiment, as shown in Figures 3 to 5, at least the light-transmitting surface 210 of the detection tube 200 is perpendicular to the detection ray transmitted from the photodetection assembly 300.

[0035] In some embodiments, as shown in Figures 3 to 5, by orienting at least the translucent surface 210 of the detection tube 200 perpendicular to the detection ray transmitted from the detection assembly 300, phenomena such as refraction generated when the detection ray passes through the translucent surface 210 of the detection tube 200 can be avoided to some extent, which affects the transmission path of the detection ray. As a result, after the detection ray has passed through the detection tube 200 and the wastewater inside the detection tube 200, the remaining detection ray maintains its basic transmission path and is received and detected by the receiver 320. Based on the intensity of the received detection ray, the amount of foreign matter in the wastewater inside the detection tube 200 is obtained, and the cleanliness of the wastewater is determined.

[0036] As one possible embodiment, the detection tube 200 is manufactured from a light-transmitting material, as shown in Figures 3 to 6.

[0037] In some embodiments, as shown in Figures 3 to 6, the detection tube 200 may be manufactured using a light-transmitting material. For example, the detection tube 200 may be manufactured using quartz glass, transparent plastic, etc., so that the detection tube 200 has a light-transmitting surface 210 used for detection. The detection tube 200 may be manufactured separately from the housing 100. The separately manufactured detection tube 200 is installed in the housing chamber, so that both ends of the detection tube communicate with the water inlet 111 and the wastewater inlet, respectively, and when wastewater flows through the housing chamber, it passes only through the detection tube 200 and does not affect the detection assembly 300 inside the housing chamber. At the same time, selectively, the housing 100 may be manufactured using a metal material or separately using a plastic material as required by the design. For example, the housing 100 is individually manufactured by an injection molding process to form a housing chamber within the housing 100 having a water inlet 111, a drain outlet 112, and a wiring hole 113, thereby allowing the detection tube 200 and the detection assembly 300 to be installed in the housing chamber of the housing 100.

[0038] In some embodiments, sealing materials such as sealants can be used to improve the sealing (sealability) of the detection pipe 200 in communication with the water inlet 111 and the wastewater outlet, thereby preventing wastewater from leaking out of the water inlet 111 and the drain outlet 112.

[0039] In some other embodiments, for example, if the light transmittance of the detection tube 200 is not required in the detection process of the detection assembly 300, the detection tube 200 itself may have light-shielding properties.

[0040] In one selectable embodiment, the housing 100 and the detection tube 200 are two-color injection molded, with the housing 100 employing a light-shielding injection molded material and the detection tube 200 employing a light-transmitting injection molded material. Alternatively, the housing 100 includes a housing 100 body and a light-shielding layer installed on the housing 100 body, with the housing 100 body and the detection tube 200 being integrally injection molded, and both the housing 100 body and the detection tube 200 employing a light-transmitting injection molded material.

[0041] In some embodiments, the housing 100 and the detection tube 200 may be manufactured by a two-color injection molding process, wherein the housing 100 is made of a light-shielding injection-molded material and the detection tube 200 is made of a light-transmitting injection-molded material. After being manufactured by the two-color injection molding process, the entire detection tube 200 is light-transmitting, thereby meeting the light-transmitting requirement of the photodetection assembly 300, while the entire housing 100 is light-shielding, thereby preventing ambient light from entering the containment chamber within the housing 100 and preventing ambient light from interfering with the detection results of the photodetection assembly 300.

[0042] In some other embodiments, the housing 100 body and the detection tube 200 may be manufactured by an integral injection molding process. The housing 100 body and the detection tube 200 may be made of a light-transmitting injection molded material. After being manufactured by the integral injection molding process, the entire housing 100 body and the detection tube 200 are light-transmitting. Selectively, a light-shielding layer can be installed on the housing 100 body to prevent ambient light from entering the containment chamber within the housing 100 and interfering with the detection results of the photodetection assembly 300, thereby preventing ambient light from entering the containment chamber within the housing 100.

[0043] In the above embodiment, the housing 100 may be made of PET (polyester resin) material and injected.

[0044] As one possible embodiment, as shown in Figures 1 to 6, a water supply fitting 1111 is provided at the water inlet 111 and a drain fitting 1121 is provided at the drain outlet 112.

[0045] In some embodiments, as shown in Figures 1 to 6, a water supply fitting 1111 is provided corresponding to the water inlet 111, and a drain fitting 1121 is provided corresponding to the drain outlet 112, so that the water supply fitting 1111 and the drain fitting 1121 protrude from the housing 100 and can be easily connected to the sewage pipe.

[0046] In some embodiments, as shown in Figures 1 to 6, the water supply fitting 1111 may be provided with a protruding anti-detachment ring that projects from the outer wall of the water supply fitting 1111, thereby preventing the wastewater pipe from becoming detached from the water supply fitting 1111 after it has been connected to the wastewater pipe. Similarly, the drain fitting 1121 may be provided with a protruding anti-detachment ring that projects from the outer wall of the drain fitting 1121, thereby preventing the wastewater pipe from becoming detached from the drain fitting 1121 after it has been connected to the wastewater pipe.

[0047] As one possible embodiment, as shown in Figures 1 to 6, a connector 114 is provided on the outside of the housing 100, and the connector 114 is used to connect to a cleaning device.

[0048] In some embodiments, as shown in Figures 1 to 6, the housing 100 may be provided with a connecting portion 114, which is used to connect to a cleaning device, thereby fixing the wastewater detection device to the cleaning device. For example, the connecting portion 114 protrudes from the housing 100, and a through hole is provided in the connecting portion 114, and a connecting member 122 such as a screw passes through the through hole and is screwed to the cleaning device, thereby fixing the housing 100 to the cleaning device, which is equivalent to fixing the entire wastewater detection device to the cleaning device.

[0049] As one selectable embodiment, as shown in Figures 1 to 8, the housing 100 includes a first housing 110 and a second housing 120, the second housing 120 engaging with the first housing 110 to form a housing chamber.

[0050] In some embodiments, as shown in Figures 1 to 8, the housing 100 may include a first housing 110 and a second housing 120. The second housing 120 can be formed surrounding the housing chamber by engaging it with the first housing 110. In some cases, the first housing 110 may serve as the main housing, with the detection tube 200 and detection assembly 300 being installed and relatively fixed within the first housing 110, and the second housing 120 engaging with the first housing 110 as a housing cover.

[0051] In some embodiments, as shown in Figures 1 to 8, the second housing 120 may be in the form of a plate when it serves as a housing cover. The plate-shaped second housing 120 can be placed over the first housing 110, forming a sealed housing chamber with the first housing 110.

[0052] In some embodiments, the shape and volume of the first housing 110 can be set based on the size specifications of the detection tube 200 and the detection assembly 300. This satisfies the requirement that the detection tube 200 and the detection assembly 300 be housed in a chamber mainly formed by the first housing 110.

[0053] In some embodiments, for example, as shown in Figures 1 to 8, the first housing 110 may be provided with screw holes, and correspondingly, the second housing 120 may have through holes. The second housing 120 can be engaged with and fixed to the first housing 110 by a screw passing through the through hole as a connecting member 122 and connecting to the screw holes. Alternatively, the first housing 110 may be provided with through holes, and correspondingly, the second housing 120 may have screw holes. The second housing 120 and the first housing 110 can be engaged with and fixed by a screw passing through the through hole and connecting to the screw holes. Optionally, as shown in Figures 1, 2, and 7, a connecting gasket 123 may be provided below the connecting member 122, thereby improving the effectiveness of the fastening connection of the connecting member 122 between the first housing 110 and the second housing 120 and preventing the connecting member 122 from rotating and falling off.

[0054] In one selectable embodiment, as shown in Figures 1 to 8, a sealing rubber sleeve 1131 is provided in the wiring hole 113, and a sealing pad 121 or a sealing ring is provided on one side of the second housing 120 facing the first housing 110.

[0055] In some embodiments, as shown in Figures 3 and 6, a sealing rubber sleeve 1131 is provided in the wiring hole 113. The sealing rubber sleeve 1131 ensures that the gap between the wiring hole 113 and the wire harness is sealed when the wire harness passes through the wiring hole 113, thereby preventing dust, water vapor, etc. from entering the housing chamber of the housing 100 through the wiring hole 113.

[0056] In some embodiments, as shown in Figures 1 and 8, a sealing pad 121 or sealing ring is provided on one side of the second housing 120 facing the first housing 110. When the second housing 120 is engaged with the first housing 110, the sealing pad 121 or sealing ring is positioned at the contact point between the second housing 120 and the first housing 110, and when the second housing 120 is connected to the first housing 110 via a fixing member such as a screw, the second housing 120 can be pressed against the first housing 110. In addition, the gap between the first housing 110 and the second housing 120 is sealed via the sealing pad 121 or sealing ring, preventing dust, water vapor, etc. from entering the housing chamber of the housing 100 through the wiring hole 113.

[0057] In the wastewater detection device of this disclosure, by installing sealing structures such as a sealing rubber sleeve 1131, a sealing pad 121, and a sealing ring, gaps or through holes on the housing 100 can be sealed, keeping the containment chamber clean and dry, thereby ensuring that the outside of the detection tube 200 is kept clean and that the detection assembly 300 is kept clean and dry. This ensures the detection effect of the detection assembly 300 while simultaneously protecting the detection tube 200 and the detection assembly 300, thereby extending the service life of the detection assembly 300 and the wastewater detection device.

[0058] In some embodiments, the sealing pad 121 may include a foam layer. The seal between the first housing 110 and the second housing 120 is achieved through the deformation of the foam layer.

[0059] As one optional embodiment, as shown in Figures 3 to 6, a fixing portion 115 and / or a positioning portion 116 are provided inside the housing 100. The fixing portion 115 is used to fix the circuit board 330, and the positioning portion 116 is used to position the circuit board 330.

[0060] In some embodiments, as shown in Figures 3 to 6, a fixing portion 115 may be provided inside the housing 100. To fix the position of the circuit board 330 within the housing chamber, the circuit board 330 can be fixed inside the housing chamber via the fixing portion 115. For example, the fixing portion 115 is a screw hole installed at the bottom of the first housing 110. Correspondingly, a fixing hole 333 is provided on the circuit board 330, and a connecting member 122 such as a screw passes through the fixing hole 333 on the circuit board 330 and is connected to the screw hole, thereby fixing the circuit board 330 to the bottom of the first housing 110.

[0061] In some embodiments, as shown in Figures 3 to 6, the transmitter 310 and receiver 320 are generally installed on a circuit board 330, and therefore the requirements for the installation position of the circuit board 330 are relatively high. In the wastewater detection device of this disclosure, a positioning section 116 is provided inside the housing 100, so that the circuit board 330 can be positioned by the positioning section 116, thereby improving the accuracy of the mounting position of the transmitter 310 and receiver 320 within the housing chamber. For example, the positioning section 116 is a positioning column installed at the bottom of the first housing 110 and protruding from the bottom of the first housing 110. Correspondingly, a positioning hole 334 is provided in the circuit board 330, and after aligning the positioning hole 334 on the circuit board 330 with the positioning column, the circuit board 330 can be installed at the bottom of the first housing 110.

[0062] As one selectable embodiment, as shown in Figures 3 to 5, the circuit board 330 includes a circuit board, a transmitting end circuit module 331 including a transmitter 310 mounted on the circuit board, and a receiving end circuit module 332 including a receiver 320. The transmitting end circuit module 331 and the receiving end circuit module 332 are either mounted on the same circuit board or on two separate circuit boards.

[0063] In some embodiments, as shown in Figures 3 to 5, in the detection assembly 300, the transmitter 310 is installed in the transmitting end circuit module 331 and the receiver 320 is installed in the receiving end circuit module 332, and the transmitting end circuit module 331 and the receiving end circuit module 332 may be installed on two circuit boards, respectively. For example, as shown in Figures 3 to 5, the two circuit boards may be installed opposite each other on both sides of the detection tube 200, so that the transmitter 310 and the receiver 320 are positioned opposite each other on both sides of the detection tube 200. In this embodiment, the two boards can be attached relatively easily to both sides of the detection tube 200 in the housing chamber, and there are no special requirements regarding whether or not there is a gap between the detection tube 200 and the first housing 110, or the size of the gap.

[0064] In some other embodiments, in the detection assembly 300, the transmitter 310 is installed in the transmitting end circuit module 331 and the receiver 320 is installed in the receiving end circuit module 332, and the transmitting end circuit module 331 and the receiving end circuit module 332 may be installed simultaneously on a single circuit board. The entire circuit board may be placed at the bottom of the first housing 110, and the transmitter 310 and the receiver 320 may be positioned on opposite sides of the detection tube 200. Since the transmitting end circuit module 331 and the receiving end circuit module 332 are installed on the same circuit board, the overall size of the circuit board is relatively large, which makes the installation of the detection assembly 300 relatively complex. In this embodiment, the detection tube 200 may be manufactured separately so that the detection assembly 300 is installed in the housing chamber before the detection tube 200 is installed in the housing chamber, thereby adjusting the installation order of the detection tube 200 and the detection assembly 300.

[0065] Based on the same inventive concept, embodiments of the present disclosure further provide a cleaning apparatus, the cleaning apparatus including the wastewater detection device.

[0066] Since the cleaning apparatus provided in this disclosure includes the wastewater detection device of the aforementioned technical proposal, the cleaning apparatus provided in this disclosure has all the beneficial effects of the aforementioned wastewater detection device, and such explanation is omitted here.

[0067] In some embodiments, the cleaning device may be a device that generates wastewater during the cleaning process, such as a handheld cleaning device, a cleaning robot, or a cleaning base station.

[0068] Unless otherwise specified or limited in this disclosure, the first feature may include direct contact between the first and second features, either "above" or "below" the second feature, or it may further include contact between the first and second features via another feature between them, without direct contact. Furthermore, "above," "above," and "on the top surface" of the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is greater than that of the second feature. "Below," "below," and "on the bottom surface" of the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0069] In this disclosure, unless otherwise specified and limited, terms such as “connection” and “fixed” should be understood in a broad sense.
