The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
Taking an anion generating device such as an electric hair dryer as an example, the currently used industry standard version is QB/T1876-2010. However, the current testing technology cannot accurately determine the capability of the devices for generating negative ions; for example, what is a device nominally an anion blower, is the concentration of anions produced able to meet national standards? It can be understood by those skilled in the art that the device under test referred to in the embodiments of the present disclosure may be any device capable of generating negative ions. For the purpose of illustration only, the electric blower is taken as an example of the device to be tested in the embodiments of the present disclosure.
In the disclosed embodiment, the device for receiving negative ions may be a metal grid, or a metal plate, or a non-metal grid, or a non-metal plate, or any appropriate shape. The device for receiving negative ions is used for receiving negative ions, and therefore the shape and material of the device for receiving negative ions are not limited in the embodiments of the present disclosure. For the purpose of illustration only, the metal induction plate is taken as an example of a device for receiving negative ions in the embodiments of the present disclosure.
To solve the above technical problem, an embodiment of the present disclosure provides a testing apparatus, see fig. 1, including a detecting device and a grounding device 20. Wherein, the detection device comprises a metal induction plate 10 provided with a grounding terminal; the metal induction plate 10 is connected with the grounding device 20 through a grounding terminal, and is used for inducing the content of negative ions in the outlet air 40 of the tested blower 30, and the content of the negative ions is used for calculating the concentration of the negative ions in the outlet air. It can be seen that, in the embodiment of the present disclosure, by setting the grounding device in the testing apparatus, the grounding device is connected to the metal induction plate in the detecting device, so that the static electricity on the metal induction plate can be guided to the ground, thereby preventing the static electricity stored in the metal induction plate from affecting the detection result, and facilitating the improvement of the accuracy of the negative ion concentration.
Wherein, the distance D is set between the tested blower 30 and the metal induction plate 10. The set distance D is a distance between a first plane and a second plane, wherein the first plane is a plane where an air outlet of the tested blower is located, and the second plane is a plane where a surface of the metal induction plate, which is close to the tested blower, is located. The set distance D can be between 5 and 20 cm. In consideration of the use habits of users, in one example, the set distance can be 10cm, so that the real distance between the hair and the tested hair dryer can be simulated, and the accuracy of obtaining the concentration of the negative ions can be improved.
In one embodiment, the detection device may comprise a DLY-3 anion concentration detector or a KEC990M II anion concentration detector. A technician may select the above-mentioned one detector to detect the concentration of the negative ions according to the requirement of a specific scenario on the detection accuracy, which is not limited herein.
In an embodiment, with continued reference to fig. 1, the test device further comprises a power supply device 40, which power supply device 40 may be a mobile power supply, or a power outlet connected to a power grid. When the tested blower is connected to the power supply device 40, the power supply device 40 can supply power to the tested blower, so as to ensure that the tested blower operates at the rated voltage and the rated power.
In one embodiment, with continued reference to fig. 1, the testing apparatus further includes a fixing frame 60, wherein the fixing frame 60 is used for fixing the tested blower 30 and enabling the fixed tested blower to be spaced from the metal induction plate by a set distance. In this embodiment can avoid it to rock through fixed being surveyed the hair-dryer and influence the anion concentration of gathering at every turn, be favorable to improving the degree of accuracy of anion concentration.
In one embodiment, with continued reference to FIG. 1, the test apparatus further includes a test platform 70. The surface of the test platform 70 is covered with an insulating layer (not shown) for placing the testing device and the tested blower 30. Like this, in this embodiment, test platform can not absorb the anion, is favorable to guaranteeing the degree of accuracy of measuring anion concentration.
In practical application, the diffusion speed of negative ions is high, so that the concentration of the collected negative ions is low in a laboratory environment or a non-laboratory environment. Wherein the laboratory environment refers to temperature (20 +/-3) DEG C, humidity: 50 percent; and no convection wind exists. To this end, in one embodiment, a relatively closed environment is constructed to mitigate the diffusion of negative ions. Referring to fig. 2 and 3, the test apparatus further includes an insulating protective cover 80. The opposite sides of the insulating protection cover 80 are respectively provided with an opening (left side and right side in fig. 2) to form an inner cavity with two open ends and a closed side, the inner cavity is used for placing the tested blower 30 and the metal induction plate 10, and the tested blower 30 and the metal induction plate 10 are distributed along the axial direction formed between the two openings; i.e. the blower 30 being tested is close to one opening and the metal sensing plate 10 is close to the other opening. Alternatively, the insulating protective cover 80 defines a passage between two openings, and air can enter the tested hair dryer through one opening to generate an air flow, and the air flow flows to the metal induction plate and flows out through the other opening.
Thus, the insulating protective cover 80 can block the airflow diffused to the periphery, so that the airflow is converged to the opening close to the metal induction plate 10, that is, the negative ions flow to the metal induction plate 10 as much as possible, which is beneficial to reducing the error of the collected negative ion concentration and improving the accuracy of the detection result.
In this embodiment, the insulating protection cover 80 may be made of an insulating material. Alternatively, the insulating protective cover 80 may include a cover body and an insulating layer provided on a surface of the cover body. Wherein, the cover body is made of rigid material and can form an inner cavity. The inner surface of the cover body can be provided with an insulating layer, and the outer surface can be selected according to specific scenes to determine whether the insulating layer is arranged.
It should be noted that, in combination with the laboratory environment or the non-laboratory environment and the insulating protective cover, the detection environment in this embodiment may include the following three types: a laboratory environment, a laboratory environment with an added insulating protective cover, and a non-laboratory environment with an added insulating protective cover. The skilled person can select at least one of the three detection environments to detect the concentration of the negative ions according to a specific scenario, and the related scheme falls within the scope of the present disclosure.
The steps of detecting the concentration of negative ions are described in conjunction with the test apparatus shown in fig. 1 to 3:
(1) the detection environment is determined.
One of the three detection environments may be selected. The detection environment is selected in this example: and increasing the laboratory environment of the insulating protective cover.
(2) And connecting the tested blower to the power supply equipment, and switching to a specified mode. Wherein the specified mode may be one of: a high speed natural wind mode, a low speed natural wind mode, or a specified wind speed mode. The air outlet speed under the designated air speed mode is 0.2-0.5 m/s, and in one example, the air outlet speed is 0.3 m/s.
The natural wind is cold wind. The natural wind is selected in this example because: the relationship between temperature and anion concentration is: the negative ion concentration is affected from high to low with temperature from high to low, but not to a great extent (about 10%). That is, the concentration of negative ions tested in hot air is about 10% higher than that tested in cold air. In other words, the negative ion concentration is tested more strictly under cold wind, so that the natural wind test is beneficial to improving the detection accuracy.
(3) And starting the tested blower and enabling the tested blower to work to a stable state. Wherein the steady state comprises: the tested blower works in the designated mode for a set time, and the variation of the concentration of the negative ions in the air outlet of the tested blower is within the preset range. The set time period may be between 5 and 15 minutes, in one example 10 minutes. The preset range can be expressed by proportion, the values are [ -5%, 5% ], and the preset range can be adjusted according to specific scenes.
(4) In a steady state, obtaining at least one set of initial concentrations representing the concentration of negative ions in the outlet air of the tested blower may include the following steps:
in a first mode
And acquiring initial concentrations according to preset intervals in a first preset time to obtain a group of initial concentrations. The first preset time can be 1-3 minutes, and the preset interval can be the same as or multiple times of the acquisition period of the detection device. Then, the peak concentration and the bottom concentration in the set of initial concentrations are obtained. Then, the average concentration of the peak concentration and the bottom concentration is obtained and used as the detection concentration. Wherein, the calculation formula of the anion concentration is as follows:
Cion＝(Cmax+Cmin)/2；
cion represents the average value of the anion concentration, and Cmax represents the peak concentration of the anion concentration within a first preset time period; cmin represents the valley concentration of the negative ion concentration within a first preset time period of the test, and the unit is as follows: ten thousand per cm 3.
For example, a set of 6 initial concentrations can be obtained by taking the initial concentrations at preset intervals of 10 seconds over a period of 1 minute. Then, peak and valley concentrations were extracted from the 6 initial concentrations. Then, the average value of the peak concentration and the bottom concentration (i.e., the average concentration) is calculated and the average concentration is set as the detection concentration of the present detection. As another example, a set of 60 initial concentrations may be obtained by collecting the initial concentrations every second over a 1 minute period. Then, peak concentrations and bottom concentrations were extracted from the 60 initial concentrations. Then, the average value of the peak concentration and the bottom concentration (i.e., the average concentration) is calculated and the average concentration is set as the detection concentration of the present detection.
Mode two
And acquiring initial concentrations according to preset intervals in a second preset time length to obtain a group of initial concentrations. Then, repeating the preset times to obtain multiple groups of initial concentrations. Wherein the preset times can be 2-10 times. After that, the average concentrations of the respective sets of initial concentrations were obtained, and the average value of all the average concentrations was obtained as the detection concentration.
For example, a set of 10 initial concentrations can be obtained by collecting the initial concentrations at preset intervals of 30 seconds over a period of 5 minutes. The average concentration of the set of 10 initial concentrations was calculated. Repeating the steps for 3 times, and calculating the average value of 3 average concentrations, wherein the average value is the detection concentration in the test process.

In practical applications, from the viewpoints of manufacturing, using, offering for sale, selling, importing and the like, the devices of the test apparatus in fig. 1 to 3 may be recombined to obtain a test apparatus with different structural compositions, and the obtained test apparatus falls within the protection scope of the present disclosure.

Thus, the insulating protective cover 80 can block the airflow diffused to the periphery, so that the airflow is converged to the opening close to the metal induction plate 10, that is, the negative ions flow to the metal induction plate 10 as much as possible, which is beneficial to reducing the error of the collected negative ion concentration and improving the accuracy of the detection result.
In this embodiment, the insulating protection cover 80 may be made of an insulating material. Alternatively, the insulating protective cover 80 may include a cover body and an insulating layer provided on a surface of the cover body.

Thus, in the present embodiment, by grounding the metal sensing plate 10, the static electricity on the metal sensing plate 10 can be guided to the ground, thereby preventing the static electricity stored in the metal sensing plate 10 from affecting the detection result, and facilitating the improvement of the accuracy of the negative ion concentration.
