Description

Technical Field

[0001] The invention relates to a testing device, and in particular to a humidifier testing device and a testing method thereof. Background Art

[0002] A humidifier is a household appliance that can increase the humidity in a room. It can humidify a designated room, or it can be connected to a boiler or central air conditioning system to humidify the entire building. Among humidifiers, ultrasonic oscillation humidifiers are the main ones. Ultrasonic humidifiers use ultrasonic high-frequency oscillations of 2 million times per second to atomize water into ultrafine particles of 1 to 5 microns and negative oxygen ions, thereby achieving uniform humidification, refreshing the air, improving health, removing the heat of winter heating, and creating a comfortable living environment.

[0003] Before the humidifier leaves the factory, various performance tests must be carried out, and it can only leave the factory after passing the tests. When testing the performance of the humidifier, it is usually not necessary to test the whole machine with a water tank. It is sufficient to use the base (host) for testing, because the performance of the humidifier is mainly reflected by the base (host). In the prior art, for the factory test of the humidifier, it is necessary to restore the normal use state of the humidifier for testing, that is, add water to the water tank (when the humidifier is in normal use, there must be water in the water tank), and let the humidifier switch between different working modes in turn. The power meter obtains the various test electrical signals on the humidifier main control circuit board in real time, and judges whether the various performances of the humidifier are qualified based on these test electrical signals. In the existing test method, water needs to be added to the water tank before testing. After the test is completed, the water needs to be poured out, cleaned, wiped, and blown dry. For large-scale humidifier testing in factories, the total amount of work of adding water, pouring water, cleaning, wiping, and blowing dry is very large, and a large amount of labor is required to complete these tasks, which greatly affects the test efficiency. Moreover, the noise generated during drying is very loud, which is a major obstacle to the noise reduction of the factory environment. Moreover, since the internal structure of the water tank is not flat and there are many channels and corners, it is not convenient to clean and wipe. In short, the existing humidifier test equipment and test methods need to be improved, the test efficiency needs to be improved, and the automation / intelligence level of the test is still low.

The pressing cylinder 40 is fixed on the crossbeam of the gantry 22 and can move downward to press the humidifier (specifically the humidifier base 100) and fix it on the workstation 211. The clamping finger cylinder 50 is fixed on the base plate 21 and is used to clamp the float 101 on the base 100. The power tester 60 is connected to the control circuit and can obtain the electrical signal on the control circuit; wherein, the side of the base plate 21 facing the gantry 22 is the front side of the base plate 21, and the side of the base plate 21 facing away from the gantry 22 is the back side of the base plate 21.

[0032] In this embodiment, the clamping finger cylinder 50 is arranged on the back side of the base plate 21, and a second through hole 212 is provided on the base plate 21. The fingers of the clamping finger cylinder 50 pass through the second through hole 212 from the back side of the base plate 21 to the front side of the base plate 21 to clamp the float 101 of the base on the work station 211.

[0033] The humidifier testing device further includes a key-operated cylinder assembly 70 , which includes a plurality of cylinders for pressing keys on the base 100 , so as to simulate the operation of the keys on the humidifier base 100 by a human hand.

[0034] Usually, the humidifier base 100 also includes a fan for blowing out water mist, which is used to blow the water mist generated by the vibration out of the humidifier. Therefore, in order to test the air outlet performance of the fan, the test device also includes an air volume sensor 80 for sensing the air volume of the fan. The air volume sensor 80 is fixed on the bottom plate 21 and installed corresponding to the position of the fan outlet nozzle 104. In this embodiment, the air volume sensor 80 is a thermal-sensitive air volume sensor. The bottom plate 21 is provided with a first through hole 213. The air outlet nozzle 104 of the fan on the base passes through the first through hole 213 from the front side of the bottom plate 21 to the back side of the bottom plate 21. The air volume sensor 80 is arranged on the back side of the bottom plate 21 and is arranged corresponding to the fan outlet nozzle 104.

[0035] The test device also includes a central control terminal 90 with a processor, the rotary cylinder 10, the pressing cylinder 40, the clamping finger cylinder 50, and the key-operated cylinder assembly 70 are all connected to the central control terminal 90 and controlled by the command action of the central control terminal 90, the power tester 60 is also electrically connected to the central control terminal 90 to send the measured data to the central control terminal 90, and the air volume sensor 80 is electrically connected to the central control terminal 90 and can feed back the measured signal to the central control terminal 90. The central control terminal 90 can be any one of a laptop computer, a desktop computer, and an industrial computer.

[0036] In this embodiment, the humidifier testing device also includes a mobile frame 200 with wheels to facilitate the displacement of the humidifier testing device. The rotating cylinder 10, the testing frame 20, the power tester 60 and the central control terminal 90 are all arranged on the mobile frame 200.

[0037] The humidifier testing method, based on the above-mentioned humidifier testing device, specifically includes the following testing steps:

[0038] Step 1: water is poured into the water storage pipe 30, but the water does not fill the entire water storage pipe 30, so as to provide a mist outlet for the water mist generated by the oscillation in the following step 3. In order to facilitate observation of whether the mist is discharged normally, the water storage pipe 30 is a transparent pipe;

[0039] Step 2, the humidifier base 100 is placed upside down on the station 211 of the bottom plate 21 (i.e., the bottom of the humidifier base 100 faces upward), so that the nozzle of the water storage pipe 30 is aligned with and covers the oscillation plate 102, and the float 101 falls under the action of gravity;

[0040] Step 2, start the pressing cylinder 40 to press the base 100 against the workstation 211 to ensure that the base 100 does not move when the test frame 20 is turned over in step 3, and start the clamping finger cylinder 50 to clamp the float 101 so that the float 101 remains in the position when there is water in the water tank;

[0041] Step 3, start the rotating cylinder 10 to flip the test frame 20 180 degrees, and at the same time drive the base 100 and the water storage pipe 30 to flip 180 degrees. At this time, the water storage pipe 30 is located above the base 21, and the water in the water storage pipe 30 contacts the oscillation plate 102 due to gravity, that is, the water in the water storage pipe 30 provides the oscillation plate 102 with the water source required for oscillation, and the oscillation mist can be achieved without adding water to the water tank 103, that is, the design of the water storage pipe 30 replaces the condition that the water tank 103 must be added with water for atomization. The position where the float 101 is maintained simulates the position of the float 101 when there is water in the water tank 103, and the humidifier is in a normal working position after being flipped;

[0042] Step 4, turn on the humidifier. The humidifier determines that there is water in the water tank 103 according to the position of the float 101, and then starts working. The oscillation plate 102 causes the water in the water storage pipe 30 to oscillate and mist. The cylinder assembly 70 is operated by pressing the buttons on the base 100 to switch the different working modes of the humidifier. The power tester 60 obtains the test signal of the humidifier in different working modes, and the air volume sensor 80 obtains the air volume of the fan in different working modes of the humidifier; at the same time, the central control terminal 90 reads the data of the power tester 60 and the air volume sensor 80 and determines the various items of the humidifier according to the data. Whether the performance meets the requirements; from this step, it can be seen that the function of the water storage pipe 30 is to store water, and the water in the water storage pipe 30 is used to come into contact with the oscillation plate 102 to be oscillated and atomized, thereby simulating the state of the humidifier being atomized. A sealing ring can be provided at the pipe mouth of the water storage pipe 30 to seal between the pipe mouth and the oscillation plate 102, so that a closed space is formed between the water storage pipe 30 and the oscillation plate 102 to prevent the water in the water storage pipe 30 from leaking out and wetting the water tank 103. The water mist generated by the oscillation in the water storage pipe 30 is eventually gathered into liquid water and continues to stay in the water storage pipe 30 for recycling.

[0043] Step 5, when the humidifier test is completed, the clamping finger cylinder 50 releases the float 101, and the float 101 falls under the action of gravity. At this time, the position of the float 101 simulates the position of the float 101 when the water tank 103 lacks water. The humidifier determines that the water tank 103 lacks water based on the position of the float 101 and automatically stops working. From then on, the entire test process is completed.

[0044] Through the above test steps, it can be seen that the test device and method described in this case can complete the test of multiple humidifiers by injecting a small amount of water into the water storage pipe at one time, without repeatedly adding water to and pouring water from the water tank to complete the test as in the existing test. Therefore, the test device and method described in this case are a technical means to subvert the tradition in the field of humidifier testing, which greatly improves production efficiency.

[0045] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
