[0029] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0030] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0031] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0032] The embodiment of the present utility model provides a water channel air tightness testing device for an electric control box, such as Figure 3-6 As shown, it includes a bottom plate 100, a positioning assembly 200 disposed on the bottom plate 100, a lower sealing assembly 300 disposed on the bottom plate 100, multiple faucet plugging assemblies 400 disposed on the bottom plate 100, a bracket 500 disposed on the bottom plate 100, and an upper sealing assembly 600 disposed on the bracket 100. The upper box 10 to be tested is used to be placed on the bottom plate 100, and the positioning assembly 200 is used to position the upper box 10 so that the upper box 10 can be stably maintained on the bottom plate 100 and its position is not easily changed, which facilitates the lower sealing assembly 300, the faucet plugging assembly 400, and the upper sealing assembly 600 to dock with it.

[0033] The faucet sealing assembly 400 is used to seal the faucet so that the faucet is airtight. The upper sealing assembly 600 includes an upper block 610 and an upper sealing ring 620 arranged on the bottom surface of the upper block 610, and the lower sealing assembly 300 includes a lower block 310 and a lower sealing ring 320 arranged on the top surface of the lower block 310. Since the upper water tank 12 and the lower water tank 13 are both stepped grooves, that is, the diameters of the openings of the upper water tank 12 and the lower water tank 13 are enlarged to form a stepped structure. The upper block 610 is used to be inserted into the upper water tank, and the upper sealing ring 620 is used to abut the inner wall of the stepped surface of the upper water tank to effectively seal the upper water tank. The lower block 310 is used to be inserted into the lower water tank, and the lower sealing ring 320 is used to abut the inner wall of the stepped surface of the lower water tank to effectively seal the lower water tank. Therefore, this embodiment can seal all openings of the water channel, and then perform an airtightness test on the water channel through an airtightness testing device, so that the test results will not be inaccurate due to leakage at the openings, thereby improving the accuracy of the airtightness test.

[0034] In some embodiments, the upper sealing assembly 600 further includes an upper actuator 630 fixed to the bracket 500. The upper actuator 630 is connected to the upper block 610 and is used to drive the upper block 610 to move vertically. When testing is required, the upper actuator 630 drives the upper block 610 downward. The upper block 610 is used to be inserted into the upper water tank. The upper sealing ring 620 is used to abut the inner wall of the stepped surface of the upper water tank to seal the upper water tank. At the same time, the compression force provided by the upper block 610 enables the lower sealing ring 320 to tightly abut the inner wall of the stepped surface of the lower water tank. When the test is completed, the upper actuator 630 drives the upper block 610 upward to remove the upper water tank, so that the tested upper box can be removed to facilitate testing of the next upper box.

[0035] Furthermore, a guide rod 640 extending vertically is fixed to the upper block 610. The bracket 500 is provided with a through-hole adapted to accommodate the guide rod 640. The guide rod 640 is inserted into and movable within the through-hole. The movement of the guide rod 640 along the through-hole provides guidance for the upper block 610, enabling stable vertical movement of the upper block 610.

[0036] In this embodiment, the upper driver 630 may be a cylinder or other driving mechanism.

[0037] In some embodiments, the faucet sealing assembly 400 includes a support block 410 fixed to the base plate 100, a side actuator 420 fixed to the support block 410, a connection block 430 connected to the side actuator 420, a pressure block 440 connected to the connection block 430, and a sealing gasket 450 fixed to the side of the pressure block 440. During testing, the side actuator 420 is used to drive the pressure block 440 toward the faucet and make the sealing gasket 450 abut the end face of the faucet. The sealing gasket 450 is made of a soft material, such as elastomeric, which can be deformed to completely seal the faucet. After the test is completed, the side actuator 420 is used to drive the pressure block 440 away from the faucet.

[0038] Furthermore, the pressing block 440 and the connecting block 430 are slidably connected along the driving direction of the side driver 420, and a spring 460 is provided between the pressing block 440 and the connecting block 430, with the two ends of the spring 460 respectively abutting the pressing block 440 and the connecting block 430. When the side driver 420 drives the pressing block 440 toward the faucet and causes the sealing gasket 450 to abut the end face of the faucet, the pressing block 440 will retract relative to the connecting block 430, and the elastic force of the spring 460 will push the pressing block 440, so that the sealing gasket 450 can tightly abut the end face of the faucet. The purpose of this arrangement is to prevent the faucet from being damaged due to excessive driving force from the side driver 420.

[0039] The pressure block 440 may be connected to a crossbar extending in the driving direction of the side driver 420. The connecting block 430 may be provided with a connecting hole adapted to fit the crossbar. The crossbar is inserted into the connecting hole and can slide along the connecting hole, thereby achieving a sliding connection between the pressure block 440 and the connecting block 430 in the driving direction of the side driver 420. The spring 460 may be sleeved on the outside of the crossbar.

[0040] Furthermore, the support block 410 is provided with a guide hole that passes through the support block 410 along the driving direction of the side driver 420. The connecting block 430 is passed through the guide hole and can slide in the guide hole to guide the movement of the connecting block 430 so that it moves stably along the driving direction of the side driver 420.

[0041] In this embodiment, the side actuator 420 may be a cylinder or other drive mechanism. A connecting pipe may be provided on the top of one of the pressure blocks 440. A first air vent is provided on the side of the pressure block 440. A sealing gasket 450 on the pressure block 440 is provided with a second air vent that interfaces with the first air vent. The connecting pipe is used to connect to an external air tightness test device, thereby performing an air tightness test on the waterway.

[0042] In some embodiments, the positioning assembly 200 includes a plurality of limit blocks 210 disposed around the upper box to be tested. The limit blocks 210 are used to abut against the side surfaces of the upper box to be tested to limit the lateral movement of the upper box on the bottom plate 100 .

[0043] Furthermore, the positioning assembly 200 further includes a plurality of positioning posts 220 , which are used to be inserted into positioning holes on the lugs of the upper box to be tested, so as to further position the upper box and keep it in a set test position.

[0044] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
