Therefore, they should not be construed as limitations on the invention. Furthermore, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc., are understood to exclude the stated number, while "above," "below," "within," etc., are understood to include the stated number. If "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0033] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0034] The following is for reference. Figure 1 and Figure 2 This invention describes a mobile spray testing device and testing method according to embodiments of the present invention.

[0035] The mobile spray testing device according to a first aspect of the present invention includes a mobile base 100, a spray chamber, a return water tank 200, and a spray assembly.

[0036] Reference Figure 1The mobile base 100 is equipped with a set of wheels at the bottom, which may include four casters 110, which are respectively located at the four corners of the mobile base 100. In addition, the mobile base 100 may also be equipped with handles, grips or other gripping components to facilitate workers to push or pull the mobile base 100.

[0037] The right side wall of the spray room has a first opening for installing the air conditioner casing 500; the first opening can simulate the structure on the side wall of the electrical cabinet for installing the cabinet air conditioner, so that the air conditioner casing is installed in the first opening to simulate the actual working state.

[0038] The return water tank 200 is located at the bottom of the spray chamber and connects the movable base 100 to the spray chamber. The right end of the return water tank 200 has a protrusion 230 extending out of the spray chamber, and the top of the protrusion 230 has a collection tank 231, which communicates with the return water tank 200. Understandably, during the testing process, water entering the air conditioner casing will drip downwards. As the testing equipment moves, the dripping water will spill extensively into the production workshop, affecting the production environment. In this embodiment, by setting up the collection tank 231, the water dripping from the air conditioner casing installed at the first opening can be collected by the collection tank 231 and flow into the return water tank 200 for reuse in the spray testing. The return water tank 200 can be configured with a first through hole at its bottom, and the top wall of the protrusion 230 can have a second through hole overlapping the first through hole, thus enabling communication between the collection tank 231 and the return water tank 200.

[0039] The spray assembly includes a nozzle 630 located inside the spray chamber and facing the first opening, a return water pipe 610 located in the return water tank 200, and a pump 620 connecting the return water pipe 610 and the nozzle 630. The nozzle 630 can spray water onto the air conditioner casing installed in the first opening for spray testing. The spilled water is collected by the return water tank 200, and the pump 620 pumps the water in the return water tank 200 to the nozzle 630 to achieve water recycling. This allows the mobile spray testing equipment to be used without constantly connecting to an external water source, i.e., without connecting to an external water pipe.

[0040] The mobile base 100 can also be equipped with testing instruments, a control unit, and a battery. The battery powers the spray assembly, testing instruments, and control unit, eliminating the need for a constant external power supply or external power cord, making the mobile spray testing equipment more flexible and convenient to move. The testing instruments include a main body and a humidity sensor. After installing the air conditioner casing in the first opening, the humidity sensor can be installed inside the casing. The instrument main body can then determine the waterproof performance of the air conditioner casing by acquiring the humidity signal detected by the humidity sensor.

[0041] In use, the mobile spray testing equipment is moved to the side of the end of the production line of the previous process. The air conditioner casing is retrieved from the previous production line and installed at the first opening. The mobile spray testing equipment is then started to perform the spray testing. During the testing process, the mobile spray testing equipment can be moved to the side of the beginning of the second production line. After testing, the air conditioner casing installed at the first opening is removed and moved to the beginning of the second production line for subsequent assembly. The entire testing process involves only one installation and one disassembly operation, which is relatively simple, reduces the labor intensity of personnel, and helps improve production efficiency.

[0042] In some embodiments of the present invention, the spray chamber is provided with a spray surface parallel to the first opening; the spray assembly includes a plurality of nozzles 630, all of which are disposed on the spray surface and spaced apart from each other. This allows for more uniform spraying of the air conditioner casing.

[0043] In some embodiments of the present invention, reference is made to... Figure 2 The spray chamber is equipped with a reciprocating mechanism, which includes two reciprocating seats 650 that are slidably disposed laterally within the spray chamber, and a second drive mechanism 651 for driving the two reciprocating seats 650 to move closer to or further away from each other. Each reciprocating seat 650 is equipped with a nozzle 630. This dynamically simulates wind and rain in nature, subjecting the air conditioner casing to multi-angle and variable-intensity impacts, making the test results more reflective of the sealing performance of the air conditioner casing under real-world usage conditions. The second drive mechanism 651 includes a bidirectional screw and a second motor for driving the bidirectional screw to rotate. The bidirectional screw has a first threaded section and a second threaded section with opposite directions of rotation. The two reciprocating seats 650 are threadedly connected to the first threaded section and the second threaded section, respectively. The second drive mechanism 651 can also be a linear motor, an electric push rod, or other linear actuator.

[0044] In some embodiments of the present invention, each reciprocating seat 650 is provided with a plurality of nozzles 630 arranged at vertical intervals. This allows for more uniform spraying of the air conditioner casing.

[0045] In some embodiments of the present invention, the spray booth is provided with a translation mechanism, which includes a translation seat 640 slidably disposed laterally in the spray booth and a first drive mechanism 641 for driving the translation seat 640 to move back and forth. The nozzle 630 is connected to the translation seat 640. This allows the position of the nozzle 630 to be adjusted so that the nozzle 630 is aligned with the air conditioner casing. The translation seat 640 is slidably disposed on the left wall of the spray booth via a guide rail slider mechanism or other sliding mechanism. The first drive mechanism 641 is a mechanism in which a motor drives a lead screw nut; the first drive mechanism 641 can also be a linear motor, an electric push rod, or other linear actuator. When a reciprocating mechanism is provided, two reciprocating seats 650 are slidably disposed on the translation seat 640 via a guide rail slider mechanism or other sliding mechanism, and the second drive mechanism 651 is also disposed on the translation seat 640.

[0046] In some embodiments of the present invention, a tooling plate 311 is detachably covered by a first opening, and the tooling plate 311 has a second opening for mounting an air conditioner housing. Multiple quick-clamping clamps 312 are provided along the edge of the first opening, pressing the edge of the tooling plate 311 against the edge of the first opening to achieve detachable installation of the tooling plate 311. By making the tooling plate 311 detachable, replacing the corresponding tooling plate 311 allows the testing equipment to be adapted to air conditioner housings of different sizes, improving the applicability of the testing equipment.

[0047] In some embodiments of the present invention, the sprinkler chamber includes a main body 300, a right wall 310, and a first flexible sealing sleeve 320 connecting the main body 300 and the right wall 310. The right wall 310 is fixedly connected to the return water tank 200, and a first opening is provided in the right wall 310. An elastic mechanism connects the main body 300 and the return water tank 200. The left edge of the first flexible sealing sleeve 320 is fixedly and sealed to the main body 300, and the right edge of the first flexible sealing sleeve 320 is fixedly and sealed to the right wall 310. The return water pipe 610 and the pump 620, as well as the pump 620 and the sprinkler head 630, are connected by flexible pipe fittings. The first drive mechanism 641 and the second drive mechanism 651 are respectively electrically connected to the main control unit via flexible wires. It is understood that although a reciprocating mechanism and a translation mechanism are provided, the movement trajectory of the sprinkler head 630 is still a certain regular trajectory, which cannot simulate the real environment of irregular spraying. In this embodiment, by setting a first flexible sealing sleeve 320 and an elastic mechanism, the main body 300 of the room and the movable base 100 are flexibly connected. When the staff pushes or pulls the movable base 100, it is inevitable to accelerate, decelerate or turn. The main body 300 of the room will sway irregularly relative to the right wall 310 of the room, further simulating the environment of irregular spraying.

[0048] Furthermore, components such as the return water tank 200, pump 620, and air conditioner casing are rigidly connected to the movable base 100, resulting in a large inertia for the movable base 100. This minimizes the impact of shaking of the main body 300 on the movement of the testing equipment, allowing for stable movement. A transparent observation window 301 is provided on the front wall of the main body 300 to facilitate external observation of the nozzle 630's operation. An electrical box 400 is located on the right wall 310 and the rear of the first flexible sealing sleeve 320, fixedly mounted on the movable base 100. Electrical components, including the control unit, are located within the electrical box 400. The pump 620 is located behind the return water tank 200, preventing the main body 300 from colliding with the electrical box 400 and the pump 620.

[0049] In some embodiments of the present invention, a drain outlet is provided at the bottom of the spray chamber, and a return water outlet is provided at the top of the return water tank 200. A second flexible sealing sleeve 220 is connected between the drain outlet and the return water outlet. This can prevent water in the spray chamber and the return water tank 200 from spilling out due to the shaking of the main body 300 and the movement of the detection equipment.

[0050] In some embodiments of the present invention, the elastic mechanism includes multiple elastic elements, which are arranged sequentially and at intervals around the outer side of the second flexible sealing sleeve 220. The elastic elements may be vertically arranged springs 210, with the top and bottom of the springs 210 fixedly connected to the main body 300 and the return water tank 200, respectively. This structure is simple and compact, avoids contact between the elastic elements and water, and improves service life.

[0051] The detection method of the second aspect of the present invention uses the above-mentioned mobile spray detection equipment to perform spray detection on the air conditioner casing. The detection method includes the following steps:

[0052] Step S100: Move the mobile spray testing equipment to the side of the end of the first production line;

[0053] Step S200: Obtain the air conditioner casing from the end of the first production line and install it into the first opening; start the mobile spray testing equipment to perform spray testing.

[0054] Step S300: Move the mobile spray testing equipment to the side of the beginning of the second production line;

[0055] In step S400, the air conditioner casing installed at the first opening is removed and moved to the beginning of the second production line.

[0056] By using the aforementioned mobile spray testing equipment, the entire testing process involves only one installation and one disassembly operation, which is relatively simple, reduces the labor intensity of personnel, and helps improve production efficiency.

[0057] In some embodiments of the present invention, step S300 further includes: moving the mobile spray testing device to a spray area for placement. In some cases, the testing time required for spray testing is relatively long, exceeding the time required to move the testing device from the first production line to the second production line. In such cases, the testing device can be moved to a specially designated spray area for placement, and then moved to the second production line after the testing is completed; charging and water replenishment can also be performed during the placement process.

[0058] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
