[0002] With technological advancements and increasing demands, consumer electronics products such as smartwatches and smart bracelets require waterproof testing. Currently, the primary method for determining water leakage is through airtightness testing. This involves placing the electronic product in a sealed container, then filling the container with gas to create a specific pressure. The pressure change within the container is then used to determine if a leak has occurred. While this method achieves the purpose of waterproofing, it cannot pinpoint the exact location of the leak. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof testing device, which aims to solve the problem that it is impossible to determine the location of leakage when testing whether electronic products leak water through air tightness tests.

[0004] This utility model discloses a waterproof testing device, which includes a water flow channel and a water flow detection structure disposed on the bottom surface of the water flow channel. The water flow detection structure is provided with multiple water tanks arranged side by side, the water tanks being arranged along the extension direction of the water flow channel. It also includes a water supply structure for supplying water to the water inlet end of the water flow channel and a transfer structure for placing electronic products on top of the water flow detection structure.

[0005] As an improvement, the water supply structure includes a water supply tank provided at the inlet end of the water flow channel, the water supply tank having an elongated water outlet adapted to the width of the water flow channel, and a water storage tank provided at the outlet end of the water flow channel, and a water pump for drawing water from the water storage tank to the water supply tank.

[0006] As an improvement, the water pump is installed inside the water storage tank, and a connecting pipe is connected between the water pump outlet and the water supply tank.

[0007] As an improvement, the connecting pipe is connected to the upper part of the water supply tank.

[0008] As an improvement, the water supply tank is located above the water flow channel, the water storage tank is located below the water flow channel, an inclined inflow channel is provided between the elongated water outlet and the inlet end of the water flow channel, and an inclined outflow channel is provided between the outlet end of the water flow channel and the water storage tank.

[0009] As an improvement, the inflow channel, the flow channel, and the outflow channel are connected as one unit; a carrier plate is provided on the side of the inflow channel away from the flow channel, and a cylindrical shell is fixed on the upper side of the carrier plate, forming the water supply tank between the cylindrical shell and the carrier plate; a support frame is provided on the side of the outflow channel away from the flow channel, and the edge of the tank opening of the water storage tank is fixedly connected to the support frame.

[0010] As an improvement, the water flow detection structure is a water flow detection plate; or, the water flow detection structure includes multiple protruding ridges arranged side by side on the bottom surface of the water flow channel, the protruding ridges being arranged along the extension direction of the water flow channel.

[0011] As an improvement, the transfer structure includes a bracket disposed on the side of the water channel, a translation drive mechanism fixed to the bracket, and a lifting drive mechanism fixed to the output of the translation drive mechanism, wherein a clamping structure is fixed to the output of the lifting drive mechanism.

[0014] As the above technical solution is adopted, the waterproof testing device of this utility model includes a water flow channel and a water flow detection structure set on the bottom surface of the water flow channel. The water flow detection structure is provided with multiple water tanks arranged side by side, which are arranged along the extension direction of the water flow channel. It also includes a water supply structure for supplying water to the water inlet end of the water flow channel and a transfer structure for placing electronic products on the water flow detection structure. During testing, water is continuously supplied from the water supply structure to the inlet of the water flow channel, forming a water flow inside the channel. Once the water flow stabilizes, it becomes a laminar flow. The electronic product is placed on a transfer structure, which then places it above the water flow detection structure and submerges it in water. The shape of the water flow in the channel is then observed. If the water flow is laminar, it indicates that the electronic product is not leaking. If the electronic product has a leakage problem, water will pass through the leak point and enter the interior of the electronic product, causing turbulence at the leak point. Leakage can be detected by observing whether turbulence occurs, and the location of the leak can be determined by the location of the turbulence. This solves the problem that it is impossible to determine the location of a leak by testing the airtightness of an electronic product. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Figure 1 and Figure 2 This is a schematic diagram of the waterproof testing device of this utility model, wherein, Figure 1 A schematic diagram of the waterproof testing device of this utility model is shown. Figure 2 A three-dimensional structural diagram of the product transfer mechanism of the waterproof testing device of this utility model is shown. For ease of description, only the parts relevant to this utility model are shown in the figure.

[0020] It should be noted that if the directional indications (such as up, down, front, back, etc.) involved in this utility model are only used to explain the relative positional relationship between the components in a certain specific posture, the directional indications will change accordingly if the specific posture changes; if the descriptions of "first", "second", etc. involved in this utility model are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0021] Depend on Figure 1 and Figure 2It is understood that the waterproof testing device of this utility model includes a water flow channel 10 and a water flow detection structure disposed on the bottom surface of the water flow channel 10. The water flow detection structure is provided with multiple water tanks arranged side by side, the water tanks being arranged along the extension direction of the water flow channel 10. It also includes a water supply structure for supplying water to the water inlet end of the water flow channel 10 and a transfer structure for placing the electronic product 80 above the water flow detection structure.

[0022] During testing, water is continuously supplied from the water supply structure to the inlet of the water flow channel 10, forming a water flow inside the channel 10. After the water flow inside the channel 10 stabilizes, it becomes a laminar flow. The electronic product 80 is placed on the transfer structure, which then places it above the water flow detection structure and immerses it in water. The shape of the water flow in the channel 10 is then observed. If the water flow is laminar, it indicates that the electronic product 80 does not leak. If the electronic product 80 has a leakage problem, water will pass through the leak location and enter the interior of the electronic product 80, causing turbulence at the leak location. Leakage of the electronic product 80 can be detected by observing whether turbulence occurs, and the location of the leak can be determined by the location of the turbulence. This solves the problem that the location of the leak cannot be determined by testing the airtightness of the electronic product 80.

[0023] In this invention, the water supply structure includes a water supply tank 31 located at the inlet end of the water flow channel 10, an elongated water outlet 311 adapted to the width of the water flow channel 10, and a water storage tank 32 located at the outlet end of the water flow channel 10.

During testing, water is filled into the water storage tank 32, and the water pump 33 is started to draw water from the water storage tank 32 to the water supply tank 31. The water drawn into the water supply tank 31 flows into the water flow channel 10 through the elongated water outlet 311, and then flows into the water storage tank 32 from the outlet end of the water flow channel 10, forming a cycle that allows for water reuse.

[0024] Specifically, the water pump 33 is installed inside the water storage tank 32, and a connecting pipe 34 is connected between the outlet of the water pump 33 and the water supply tank 31. Usually, the connecting pipe 34 is connected to the upper part of the water supply tank 31.

This facilitates the smooth flow of water from the water supply tank 31 into the water flow channel 10 and the smooth flow of water from the water flow channel 10 into the water storage tank 32, preventing backflow that could affect the water flow inside the water flow channel 10.

The protruding ribs 22 are disposed along the extension direction of the water flow channel 10, and a water trough is formed between adjacent protruding ribs 22.

[0028] In some other embodiments, the water flow detection structure includes multiple protruding ribs 22 arranged side by side on the bottom surface of the water flow channel 10. The protruding ribs 22 are arranged along the extension direction of the water flow channel 10, that is, the water flow detection structure and the water flow channel 10 are integrated into one structure.

[0030] Specifically, the bracket 40 is fixedly connected to the water flow channel 10, and the translation drive mechanism 50 is set along the extension direction of the water flow channel 10.

[0031] like Figure 2 As shown, the clamping structure 70 includes a base 71 fixed to the output part of the lifting drive mechanism 60. A slot 711 is provided on one side of the base 71. A first through hole 712 and a second through hole 713 communicating with the slot 711 are respectively provided on the upper and lower sides of the base 71. It also includes a pressure block 72 that engages inside the slot 711 and a sliding drive mechanism 73 for driving the pressure block 72 to move towards / away from the bottom surface of the slot 711. When placing the electronic product 80, the electronic product 80 is passed through the first through hole 712 and the second through hole 713. Then, the sliding drive mechanism 73 drives the pressure block 72 to move towards the bottom surface of the slot 711, clamping the electronic product 80 between the pressure block 72 and the bottom surface of the slot 711.

[0032] Specifically, an arc-shaped groove 714 is provided on the bottom surface of the slot 711 between the first through hole 712 and the second through hole 713.
