[0039] Figure 2 is a structural diagram of a ventilation module according to an exemplary embodiment. As Figure 2As shown, the ventilation module includes a first ventilation plate 5 and a second ventilation plate 8. The first ventilation plate 5 and the second ventilation plate 8 are both used to blow air to the faucet handle 2, so that the faucet handle 2 can be moved in a touchless manner. The first ventilation plate 5 can be arranged at a starting position of the faucet handle 2, and the second ventilation plate 8 can be arranged at an ending position of the faucet handle 2. The starting position of the faucet handle 2 may, for example, refer to a state in which a valve core of the faucet is in a closed state. At this time, the first ventilation plate 5 can be arranged on the lower side of the faucet handle 2 when the faucet is closed. The ending position of the faucet handle 2 refers to the position of the faucet handle 2 after the faucet is opened. The second ventilation plate 8 can be arranged on the upper side of the faucet handle 2 when the faucet is opened. Specifically, the faucet handle 2 is arranged between the first ventilation plate 5 and the second ventilation plate 8. During the test of the faucet handle 2, the faucet can not be connected to a water source. The starting position and the ending position of the faucet handle 2 are not limited in the utility model, and the starting position of the faucet may, for example, be 0°, and the ending position can be the position at which the faucet handle 2 is fully opened. At this time, the faucet handle 2 can be 90°, and the angle between the first ventilation plate 5 and the second ventilation plate 8 can be arranged to be between 0° and 90°.

[0040] In a possible implementation, the ventilation module further includes a first ventilation box 4 and a second ventilation box 1. The first ventilation plate 5 is fixedly connected to the first ventilation box 4, and the second ventilation plate 8 is fixedly connected to the second ventilation box 1. Specifically, the first ventilation plate 5 is arranged on the first ventilation box 4, and the second ventilation plate 8 is arranged on the second ventilation box 1. The first ventilation box 4 and the second ventilation box 1 are both arranged in a sealed structure, which is used to prevent external gas or liquid from entering the inside of the box body.

[0041] In a possible implementation, the faucet test device further includes a gas source conveying end. The gas source conveying end is used to provide a gas flow and a gas pressure to the first ventilation box 4 and the second ventilation box 1 in the faucet test device. The gas source conveying end can be a compressed air tank, a gas compressor or other gas sources capable of providing a stable gas flow. The utility model does not limit this.

[0042] The faucet test device further includes a first pipeline and a second pipeline. The first pipeline is a pipeline connecting the gas source conveying end and the first ventilation box 4. The second pipeline is a pipeline connecting the gas source conveying end and the second ventilation box 1. Specifically, one end of the first pipeline is connected to the gas source conveying end, and the other end is sealingly connected to the air inlet hole of the first ventilation box 4. One end of the second pipeline is connected to the gas source conveying end, and the other end is sealingly connected to the air inlet hole of the second ventilation box 1.

[0043] The air inlet hole of the first ventilation box 4 can be arranged on the side away from the faucet handle 2, and the air inlet hole of the second ventilation box 1 can also be arranged on the side away from the faucet handle 2.

[0044] Figure 3 is a structural diagram of a venting plate according to an exemplary embodiment. As shown in Figure 3 The first venting plate 5 and the second venting plate 8 are respectively provided with a plurality of venting holes 9, and the number of the venting holes 9 is not limited in the utility model. Preferably, the number of the venting holes 9 on the first venting plate 5 and the number of the venting holes 9 on the second venting plate 8 are both set to 28, the aperture of the venting hole 9 can be set to 3 mm, the air pressure delivered by the air source delivery end can be set to 0.4 MPa, and then the thrust generated by each venting hole 9 can be calculated as 0.4 MPa x the area of the venting hole 9; and then the thrust generated by each venting hole 9 can be calculated as 0.2826 N; and further, the total thrust of each venting plate can be determined to be about 7.9128 N. The utility model does not limit this, and the thrust generated by the venting module can be adjusted by changing the air pressure output by the air source delivery end or the number and aperture of the holes.

[0045] In a possible implementation, the faucet testing device further comprises a gas sensor. The gas sensor is a device capable of detecting the presence, concentration or composition of a specific gas. The gas sensor can be an infrared gas sensor, a semiconductor gas sensor or an electrochemical gas sensor, and the type of the gas sensor is not limited in the utility model. The gas sensor is connected to the faucet testing system corresponding to the faucet testing device. The gas sensor is arranged at both ends of the first pipeline and both ends of the second pipeline. Specifically, the gas sensor is connected to the transmission interface of the air source delivery end, and the gas sensor is also connected to the venting holes 9 of the first venting box 4 and the second venting box 1, for monitoring the air pressure conditions at the connection between the first pipeline and the air source delivery end and the first venting box 4, and the air pressure conditions at the connection between the second pipeline and the air source delivery end and the second venting box 1. The gas sensor transmits the air pressure conditions to the faucet testing system corresponding to the faucet testing device. The faucet testing system receives the air pressure conditions and analyzes them. If the air pressure conditions are greater than the first preset air pressure, it indicates that the pipeline leaks.

[0046] In a possible implementation, a corresponding buzzer alarm can be arranged on the faucet testing device. In the case of a gas leak, the faucet testing system sends an alarm instruction to the buzzer alarm. After receiving the alarm instruction, the buzzer alarm immediately sounds an alarm, so that the operator can check and replace the leaking component in time, thereby improving the detection efficiency of the faucet testing device.

[0047] Figure 4 is a structural diagram of a venting module according to an exemplary embodiment. As shown in Figure 4As shown, the ventilation module is further provided with a rotating frame 10, and the first ventilation box 4 and the second ventilation box 1 are both arranged on the rotating frame 10. Exemplarily, the first ventilation box 4 and the second ventilation box 1 can be integrally arranged with the rotating frame 10, and the utility model does not make limitation on this. The rotating frame 10 is used to drive the first ventilation box and the second ventilation box to reciprocate around the rotating frame 10 in the circumferential direction.

[0048] In a possible implementation, the faucet testing device further comprises a rotary cylinder 3. The rotary cylinder 3 is a mechanical device that converts linear motion into rotary motion. The working principle of the faucet testing device is that, in the rotary cylinder 3, the piston reciprocates along the cylinder axis under the action of gas pressure. This linear motion is converted into rotary motion output through a certain conversion mechanism, such as a crankshaft.

[0049] In a possible implementation, the rotary cylinder 3 comprises a cylinder body, a piston and an output shaft. The cylinder body is the main part of the rotary cylinder 3 and contains the piston inside; the piston is tightly fitted with the inside of the cylinder body, used to divide different pressure areas and prevent gas leakage through the seal on it; one end of the output shaft is connected with the piston, and the other end is connected with the ventilation module. When the piston moves, the output shaft rotates, thereby driving the ventilation module to reciprocate within a set range. Exemplarily, the rotary cylinder 3 is a pneumatic or hydraulic actuator that converts gas pressure or hydraulic pressure into mechanical energy, thereby generating rotary motion. Further, the output shaft, i.e. the piston rod, drives the rotating frame 10 connected thereto to reciprocate, i.e. to reciprocate between the starting position and the end position of the faucet handle 2.

[0050] In a possible implementation, the rotary cylinder 3 is further provided with a throttle valve, which is arranged at the air inlet of the piston. By limiting the flow of gas, the throttle valve can control the movement speed of the piston.

[0051] The faucet testing system can control and adjust the movement speed of the rotary cylinder 3 by controlling the gas flow of the throttle valve. Exemplarily, when the rotation speed of the ventilation module needs to be slowed down, the faucet testing system can control the valve port of the throttle valve to be reduced, thereby reducing the gas flow, so as to slow down the movement speed of the piston, and further, the rotation speed of the rotating frame 10 can be slowed down. Conversely, when the rotation speed of the ventilation module needs to be accelerated, the faucet testing system can control the valve port of the throttle valve to be enlarged, thereby increasing the gas flow, so as to speed up the movement speed of the piston, and further, the rotation speed of the rotating frame 10 can be accelerated.

[0052] In a possible implementation, during the life test of the faucet handle 2, when the faucet is at the starting position, for example, at the 0° position, the gas source delivery end supplies gas to the first aeration box 4, which is discharged to the faucet handle 2 through the plurality of aeration holes 9 on the first aeration plate 5, thereby pushing the faucet handle 2 to rotate. At the same time of blowing, the rotary cylinder 3 is opened, and the output shaft drives the rotating frame 10 to rotate along the circumferential direction thereof to the second aeration plate 8, and then the first aeration plate 5 moves to the end position of the faucet handle 2. After the faucet handle 2 moves to the end position, the gas source delivery end stops supplying gas to the first aeration box 4, at this time, the rotary cylinder 3 drives the rotating frame to move along the circumferential direction thereof to the first aeration plate 5, that is, the first aeration plate 5 is turned to the starting position. Further, the gas source delivery end supplies gas to the second aeration box 1, thereby pushing the faucet handle 2 to return to the starting position.

[0053] In a possible implementation, the faucet test device can also be provided with an angle sensor, which can be arranged on the side of the faucet handle 2 and connected with the faucet test system, and is used for monitoring the rotation angle of the faucet handle 2. The angle sensor monitors the moving range of the faucet handle 2 in real time, and when it is monitored that the faucet handle 2 reaches the starting position or the end position, for example, the faucet handle 2 is at 0° or 90°, the utility model does not make a limitation on this. At this time, the angle sensor sends the angle information to the faucet test system, and after the faucet test system receives the angle information, the moving angle of the faucet handle 2 is immediately analyzed, and in the case that the faucet handle 2 moves to the end position, the gas source delivery end is controlled to stop aeration to the first aeration box 4, and at the same time, the rotary cylinder 3 is controlled to reverse, that is, the rotating frame is controlled to rotate along the direction of the first aeration box. In the case that the first aeration box 4 moves to the starting position, the gas source delivery end is immediately controlled to aerate the second aeration box 1, at this time, the second aeration plate 8 blows the faucet handle 2 to move from the end position to the starting position.

[0054] In a possible implementation, the faucet test device further comprises a counter, which is connected with the faucet test system and is used for recording the number of actions of the faucet handle 2, wherein one action of the faucet handle 2 is from the starting position to the end position and then from the end position to the starting position. The faucet test system can set a corresponding test number, for example, five thousand times, and the utility model does not make a limitation on the test number. When the number recorded by the counter reaches the test number, the rotary cylinder 3 and the gas source delivery end are immediately stopped to work. The operator detects the faucet handle 2 to judge whether the faucet handle 2 can be normally used.

[0055] In a possible implementation, the faucet testing device is further provided with air pressure detection sensors, which can be arranged on the first air plate 5 and the second air plate 8. The air pressure detection sensors are used to detect whether the air pressure of the air blown from the first air plate 5 and the second air plate 8 meets a preset air pressure. In the case that the air pressure of the blown air does not meet the preset air pressure, the air pressure of the air source delivery end is increased, so that the air pressure generated by the first air plate 5 and the second air plate 8 can push the faucet handle 2 to move.

[0056] In a possible implementation, the faucet testing device is further provided with a faucet base and a cylinder base 6, the faucet is arranged on the faucet base 7, the rotary cylinder 3 is arranged on the cylinder base 6, and the cylinder base 6 is arranged on the faucet base 7, thereby improving the reliability and firmness of the faucet testing device.
