In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] like Figure 1-5 As shown, an embodiment of the present invention provides a nozzle detection system, which includes a mounting base 1, a detection water tank 2, a collecting water tank 3, a nozzle 5 and a plugging member 8. The detection water tank 2 is mounted on the mounting base 1, a drainage hole is provided at the bottom of the detection water tank 2, the collecting water tank 3 is detachably mounted on the mounting base 1, the collecting water tank 3 is located below the detection water tank 2, the nozzle 5 is used to spray water onto the inner wall of the detection water tank 2, the plugging member 8 is located above the collecting water tank 3, and the plugging member 8 can move relative to the detection water tank 2, so that the plugging member 8 can selectively connect or disconnect the drainage hole with the collecting water tank 3.

[0044] The nozzle 5 is used to spray water onto the inner wall of the detection water tank 2. The quality of the nozzle 5 can be tested based on the height and strength of the water spray. The plugging member 8 is in a position to connect the drain hole with the collection water tank 3. The water in the detection water tank 2 flows into the collection water tank 3 through the drain hole. The nozzle 5 can continue to spray water into the detection water tank 2 to continuously test the quality of the nozzle 5. When the water in the collection water tank 3 needs to be cleaned, the plugging member 8 is moved to disconnect the drain hole from the collection water tank 3. The water in the detection water tank 2 cannot flow into the collection water tank 3 through the drain hole. At this time, the collection water tank 3 is disassembled and the water in the collection water tank 3 is processed in time. Since the drain hole of the plugging member 8 is disconnected from the collection water tank 3, the nozzle 5 can continue to spray water for testing during the process of processing the water in the collection water tank 3.

[0045] Exemplarily, the mounting base 1 is L-shaped, and the water collecting tank 3 is pullably mounted on the mounting base 1 along a first horizontal direction. Specifically, a pull-out groove is provided on the mounting base 1, and the water collecting tank 3 is pullably disposed in the pull-out groove along a first direction.

[0046] Furthermore, the projection of the drainage hole on the horizontal plane is the first projection, the projection of the top opening of the collection water tank 3 on the horizontal plane is the second projection, and the first projection is located inside the second projection.

[0047] The first projection is located inside the second projection, so that the water sprayed into the detection water tank 2 by the nozzle 5 can flow into the collection water tank 3 through the drainage hole in time, thereby preventing the water in the detection water tank 2 from accumulating due to failure to flow out in time and affecting the detection result of the nozzle 5.

[0048] Furthermore, if Figure 2As shown, a groove 10 is provided on the upper surface of the mounting base 1 , a through hole is provided at the bottom of the groove 10 , the upper surface of the mounting base 1 supports the lower bottom wall of the detection water tank, and the through hole is connected to the top opening of the collection water tank 3 .

[0049] The upper surface of the mounting base 1 is provided with a groove 10, and the bottom of the groove 10 is provided with a through hole, which is connected with the top opening of the collecting water tank 3. The water in the detection water tank 2 flows into the groove 10 through the drainage hole, and the water in the groove 10 flows into the collecting water tank 3 through the through hole. The groove 10 has a certain depth and can accumulate a certain amount of water. The plugging member 8 is in a position to disconnect the drainage hole from the collecting water tank 3. During the period when the water in the collecting water tank 3 is cleaned, the nozzle 5 can continue to spray water into the detection water tank 2 to ensure that the water in the detection water tank 2 is discharged into the groove 10 in real time. Since the accumulation of a certain amount of water in the detection water tank 2 will affect the detection result of the nozzle 5, the groove 10 can temporarily store the water flowing out of the detection water tank 2, ensure that there is less water in the detection water tank 2, improve the detection effect of the nozzle 5, and facilitate the detection of the quality of the nozzle 5.

[0050] Preferably, the drainage hole is directly opposite to the through hole, and the first projection is located inside the projection of the through hole on the preset plane.

[0051] Furthermore, the nozzle detection system also includes a driving unit, which has a first output end and a second output end. The first output end can be raised and lowered in a vertical direction, the first output end is connected to the nozzle 5, and the second output end is connected to the blocking member 8.

[0052] The first output end and the second output end share a driving unit, which can simultaneously control the lifting of the nozzle 5 and the movement of the blocking member 8, thereby reducing the number of driving units and saving costs. The first output end can adjust the lifting of the nozzle 5, and is used to adapt and detect the spray intensity and spray distance of different models of nozzles 5 at different heights. The second output end can control the movement of the blocking member 8 relative to the mounting seat 1, and is used to connect or disconnect the drainage hole with the collection tank 3.

[0053] It should be noted that different types of nozzles 5 have different parameters such as size and atomization pressure, so it is necessary to appropriately adjust the height of the nozzle 5 relative to the detection water tank 2. In the process of adapting different types of nozzles 5, it is necessary to ensure that the blocking member 8 cannot completely block the drainage hole. When the water in the collection water tank 3 needs to be cleaned, the blocking member 8 blocks the drainage hole. Although the nozzle 5 is lifted and lowered and the blocking member is moved by a driving unit, the height of the nozzle 5 will change accordingly, but the change in the height of the nozzle 5 has a negligible effect on its detection result.

[0054] Exemplarily, the test water tank 2 is a transparent water tank with scales. During the test of the nozzle 5, the operator judges the quality of the nozzle 5 by observing the angle, distance and other parameters of the water mist sprayed by the nozzle 5.

[0055] Furthermore, a mounting groove 9 is provided on the mounting seat 1 , and a blocking member 8 is slidably disposed in the mounting groove 9 along a first horizontal direction. A sealing member is provided between the mounting groove 9 and the blocking member 8 , and the sealing member is used to seal the opening side of the mounting groove 9 .

[0056] A seal is provided between the mounting groove 9 and the sealing member 8, and the seal is used to seal the opening side of the mounting groove 9, so as to prevent the water in the detection water tank 2 from flowing into the mounting groove 9 through the drainage hole and then into the mounting base 1 equipped with the drive unit, thereby effectively avoiding malfunction of the drive unit.

[0057] Exemplarily, the opening direction of the mounting groove 9 is opposite to the opening direction of the pull-out groove, so that the driving unit can be prevented from affecting the pulling out of the collection water tank 3. It should be noted that the opening of the pull-out groove can also be opened on the side wall of the mounting base 1 adjacent to the side where the driving unit is located.

[0058] like Figure 2 As shown, the mounting seat 1 includes a first mounting seat 101 and a second mounting seat 102. The first mounting seat 101 is an L-shaped structure. The first mounting seat 101 includes a connected vertical end 1011 and a horizontal end 1012. The second mounting seat 102 is arranged on the horizontal end 1012 and supported by the horizontal end 1012. The structure between the bottom wall of the groove 10 and the upper inner wall of the draw-out groove forms a mounting structure. One end of the mounting groove 9 is arranged in the mounting structure, and the other end extends to the end face of the vertical end 1011 facing the second mounting seat 102. One end of the through hole extends to the bottom wall of the groove 10, and the other end extends to the upper inner wall of the draw-out groove. The blocking member 8 is slidably arranged in the mounting groove 9. By controlling the movement of the blocking member 8 in the mounting groove 9, the blocking member 8 can cut off the through hole, so that the groove 10 and the collecting water tank 3 below are not connected, and the continuous detection of the nozzle 5 can be ensured. Such arrangement makes the mounting base 1 have a relatively high integration level, a relatively simple structure and a low cost.

[0059] Furthermore, the mounting groove 9 is provided with a first inclined surface, which is arranged along the first horizontal direction between the drainage hole and the bottom wall of the mounting groove 9, and the first inclined surface is arranged on the lower side wall of the mounting groove 9. From top to bottom, the first inclined surface gradually approaches the drainage hole.

[0060] The water in the detection water tank 2 flows into the installation groove 9 through the drainage hole. The installation groove 9 is provided with a first inclined surface so that the water in the installation groove 9 can flow into the collection water tank 3 along the first inclined surface. This can prevent water from accumulating in the installation groove 9 for a long time and generating odor, thereby affecting the detection experience of the nozzle detection system.

[0061] Furthermore, if Figure 3As shown, the driving unit includes a driving motor 12, a lead screw 13 and a slider 14. The driving motor 12 is installed on the mounting base 1, the lead screw 13 is connected to the output shaft of the driving motor 12, the slider 14 is threadedly connected to the lead screw 13 and is restricted from rotating relative to the mounting base 1, and the slider 14 forms a first output end, which is connected to the second output end through a transmission unit.

[0062] The drive motor 12 is turned on, and the output shaft of the drive motor 12 starts to rotate, and the output shaft drives the lead screw 13 to rotate, and the lead screw 13 drives the slider 14 to rotate. Since the slider 14 is restricted from rotating relative to the mounting seat 1, the slider 14 rises and falls in the vertical direction with the rotation of the lead screw 13, and the slider 14 forms a first output end. The slider 14 is connected to the second output end through a transmission unit, and the lifting of the slider 14 can drive the second output end to move relative to the mounting seat 1. The slider 14 drives the nozzle 5 to rise and fall, and the lifting of the nozzle 5 can be controlled by the drive motor 12, and the detection results of the nozzle 5 at different lifting heights can be detected. At the same time, the second output end can control the movement of the blocking member 8, which is used to connect or disconnect the drain hole with the collection tank 3 to ensure that the nozzle 5 can be continuously detected.

[0063] Furthermore, the driving unit is installed in the mounting base 1 , the mounting base 1 is provided with a lifting hole 11 , one end of the slider 14 passes through the lifting hole 11 in the horizontal direction, and the slider 14 is slidably connected with the lifting hole 11 in the vertical direction.

[0064] Under the action of the lead screw 13, the slider 14 will rotate along the circumferential direction of the lead screw 13. Since one end of the slider 14 passes through the lifting hole 11, the lifting hole 11 and the slider 14 slide together in the vertical direction, which can limit the slider 14 from rotating along the circumferential direction of the lead screw 13, so that the slider 14 can be lifted and lowered in the vertical direction.

[0065] Exemplarily, the slider 14 is provided with a convex portion along the first horizontal direction, the convex portion passes through the lifting hole 11 , and the inner wall of the lifting hole 11 contacts the convex portion, thereby limiting the slider 14 from rotating along the circumferential direction of the lead screw 13 .

[0066] Furthermore, the transmission unit includes a first rack 140, a first gear 141, a first bevel gear 142, a second bevel gear 144, a first pulley 145, a second pulley 147, a second gear 149 and a second rack 151. The first rack 140 is installed on the slider 14, the first gear 141 is meshed with the first rack 140, the first bevel gear 142 and the first gear 141 are both fixed to the first shaft 143, the first shaft 143 is rotatably connected to the mounting base 1, the second bevel gear 144 is meshed with the first bevel gear 142, the first bevel gear 142 is transmission-connected to the second gear 149, the second rack 151 is installed on the sealing member 8, and the second gear 149 is meshed with the second rack 151.

[0067] The drive motor 12 is turned on, and the output shaft of the drive motor 12 rotates to drive the lead screw 13 to rotate, and the lead screw 13 drives the slider 14 to rise and fall, and the first rack 140 rises and falls with the slider 14, and the first rack 140 drives the first gear 141 to rotate, and the first gear 141 rotates coaxially with the first bevel gear 142 through the first shaft 143, and the first bevel gear 142 drives the second bevel gear 144 to rotate. Since the second bevel gear 144 is connected to the second gear 149 by transmission, the second bevel gear 144 drives the second gear 149 to rotate, and the second gear 149 is meshed with the second rack 151, and the second rack 151 will move along the first horizontal direction, thereby driving the blocking member 8 to move along the first horizontal direction. The blocking member 8 can connect or disconnect the drain hole with the collection tank 3, to ensure that the nozzle 5 detection and wastewater treatment can be carried out at the same time, thereby improving the detection efficiency of the nozzle 5.

[0068] like Figure 3-5 As shown, the transmission unit also includes a second shaft 146, a first pulley 145 and a second pulley 147. The first pulley 145 is located below the second bevel gear 144. The first pulley 145 and the second bevel gear 144 are both fixed to the second shaft 146. The second shaft 146 is rotatably connected to the mounting base 1. The second pulley 147 is horizontally spaced from the first pulley 145. The first pulley 145 is connected to the second pulley 147 through a conveyor belt 148. The second bevel gear 144 rotates coaxially with the first pulley 145 through the second shaft 146. The first pulley 145 drives the second pulley 147 to rotate through the conveyor belt 148. The second pulley 147 rotates coaxially with the second gear 149 through the third shaft 150. The second gear 149 drives the second rack 151 to move along the first horizontal direction. In other embodiments, the first pulley 145 and the second pulley 147 can also be replaced by gears.

[0069] It should be noted that the transmission ratio set by the transmission unit is greater than 5, so that the ratio of the horizontal movement speed of the blocking member 8 to the lifting speed of the slider 14 is greater than 5, thereby greatly reducing the lifting height of the slider 14 when the blocking member 8 opens and closes the drainage hole.

[0070] Furthermore, the nozzle detection system also includes a reset member 15, which is connected to the blocking member 8. The reset member 15 can provide an axial force along a first horizontal direction to the blocking member 8, so that the blocking member 8 has a tendency to move toward the side connected to the drainage hole and the collection water tank 3.

[0071] Exemplarily, the reset member 15 is a tension spring, located at the opening side of the mounting groove 9, one end of the reset member 15 is connected to the blocking member 8, and the other end is connected to the mounting seat 1. In other embodiments, the reset member 15 is a compression spring, the blocking member 8 is arranged between the reset member 15 and the driving unit along the first direction, one end of the reset member 15 is connected or abutted to the mounting seat 1, and the other end is connected or abutted to the blocking member 8.

[0072] Preferably, two groups of reset members 15 are provided, and the two groups of reset members 15 are located at both ends of the blocking member 8 in the second horizontal direction, so that the blocking member 8 can be effectively reset when switching between the connection and disconnection of the drain hole and the collection water tank 3 .

[0073] Furthermore, the nozzle detection system also includes a fixing member 4 , which is connected to the slider 14 , and the nozzle 5 is detachably mounted on the fixing member 4 , so as to facilitate replacement of different types of nozzles 5 .

[0074] Furthermore, the nozzle detection system also includes a liquid level detection unit and a reminder unit. The liquid level detection unit is installed in the collection tank 3. The liquid level detection unit is used to detect whether the liquid level in the collection tank 3 reaches a preset liquid level. The reminder unit is used to remind the user that the liquid level in the detection tank 2 has reached the preset liquid level.

[0075] The nozzle detection system also includes a controller, and the liquid level detection unit and the reminder unit are both connected to the controller in communication. The liquid level in the collection tank 3 can be detected by the liquid level detection unit. If the liquid level reaches a preset level, the liquid level detection unit transmits a signal to the controller, and the controller controls the plugging member 8 to disconnect the drain hole from the collection tank 3. The controller also transmits a signal to the reminder unit, and the reminder unit sends a reminder signal to facilitate the staff to deal with the water in the collection tank 3 in time. Exemplarily, the liquid level detection unit is a liquid level sensor.

[0076] Continue as Figure 1-3 As shown, the water in the water storage tank 7 is transported to the nozzle 5 through the water pipe 6 by the water pump, and the water is sprayed into the inner wall of the detection water tank 2 under the pressure of the nozzle 5, and the spraying intensity and spraying distance of the water sprayed by the nozzle 5 in the detection water tank 2 are detected. The driving motor 12 is started to drive the slider 14 to rise and fall, and the slider 14 drives the nozzle 5 to rise and fall, so that the spraying intensity and spraying distance of the nozzle 5 at different heights can be detected. The lifting of the slider 14 drives the blocking member 8 to move along the first horizontal direction, so that the blocking member 8 connects or disconnects the drainage hole with the collection water tank 3. When the drain hole is connected to the water collection tank 3, the water in the detection water tank 2 can flow into the water collection tank 3 in time, ensuring that the nozzle 5 continuously sprays water into the detection water tank 2; when the water flowing into the water collection tank 3 reaches the preset liquid level, the plugging member 8 is in a position to disconnect the drain hole from the water collection tank 3, and the reminder unit sends a reminder signal to remind the user to clean the water in the water collection tank 3 in time. Since the mounting seat 1 is provided with a groove 10, a certain amount of water can be accumulated. During the cleaning of the water in the water collection tank 3, it is ensured that the nozzle 5 can continue to spray water into the detection water tank 2, and the spraying intensity and spraying distance of the nozzle 5 are continuously tested. After the cleaned water collection tank 3 is inserted into the mounting seat 1, the plugging member 8 is moved to connect the drain hole with the water collection tank 3, and the water accumulated in the groove 10 is drained to the water collection tank 3, and the cycle is repeated.

[0077] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
