Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of product testing, in particular, especially relates to a test method of a handheld massager. BACKGROUND

[0002] The suction type structure is widely used in consumer products such as handheld massagers. The testing and standard design of such products have attracted more and more attention. The traditional suction type handheld massager structure is shown in patents CN214049649U and CN214049650U, which generally includes a motor and a connecting rod connected by an eccentric structure. The other side of the connecting rod is connected to an air chamber. Specifically, the motor rotates to drive the connecting rod to push to the far end side, causing the volume of the air chamber to be compressed, so that the pressure in the air chamber increases. When the connecting rod moves to the near end side, the volume of the air chamber increases, causing the pressure in the air chamber to decrease.

[0003] In actual production, the qualification test of the suction type handheld massager product is generally carried out by manual operation. Such manual test has the characteristics of inaccuracy. At the same time, the manual test can only test one handheld massager at a time, which has the problem of low efficiency. In the case of manual test, there is no unified judgment standard, and the single instrument is tested separately, which may also cause some massage instruments to be missed, undetected, or incorrectly detected.

[0004] Since the manual test method cannot provide accurate data for product qualification test, there may be corresponding system errors in the test process. Such errors cannot be avoided in the operation process, but always exist, so a more accurate test method is needed to test the product more accurately, and the test data is presented by data to reflect the qualification degree of the product. SUMMARY

[0027] Third, set T2 as the product's pause time; the product's pause time is calculated by the following formula,

[0028] T2 = T Sn / fc(T2 < t g ), wherein: t g is the maximum value of the product's pause time set according to the product mode.

[0029] Fourth, compare the T1 and T2 values calculated by the test with the pre-stored mode values to obtain the working mode of the product.

[0035] Figure 1 : A flowchart of a preferred embodiment of the present invention. Detailed Implementation

[0036] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0037] like Figure 1 As shown, this invention discloses a testing method for a suction-type handheld massager, comprising the following steps:

[0038] Step S1: Start the motor of the suction-type handheld massager and measure the air pressure value in the air chamber through the air pressure sensor. The air pressure sensor model is MP3H6115A.

[0039] The pressure value is converted into an electrical signal according to the following formula, where the electrical signal is the output voltage.

[0040] V OUT =V S *(0.009*P n –0.095), where V OUT V is the output voltage. S =3.0±0.3VDC, P n The current test reads the air pressure value inside the chamber; simultaneously, the electrical signal is corrected according to a temperature compensation algorithm;

[0041] Step S2: Filter and shape the electrical signal;

[0042] Step S3: Extract the frequency, amplitude, and period of the electrical signal, and determine the working speed, working mode, and working duration of the motor of the suction-type handheld massager accordingly;

[0043] Step S4, charging and discharging detection steps for the power module. For example: 1. Charging detection: The charging status of the product can be determined by the current value of the charging circuit, whether it is charging or fully charged. 2. Discharging detection: The discharging time of the product can be calculated based on the cumulative working time of the product in a fully charged state.

[0044] In step S3, specifically, the operating speed fm of the motor is obtained by testing according to the following formula.

[0045]

[0046] Where: P G : Set air pressure threshold; P n : The air pressure value currently being tested and read from the air chamber; fc: Sampling frequency;

[0047] T Tn =P n -P G T Tn >0, the cumulative number of times the current air pressure value has exceeded the air pressure threshold.

[0048] T Bn =P G -P n T Bn >0, the cumulative number of times the current air pressure value is less than the air pressure threshold.

[0049] T Cn =P G -P n T Cn =0, the current air pressure value is equal to the cumulative number of times the air pressure threshold is reached.

[0050] Wherein: T Tn +T Bn T represents the total number of air pressure measurements collected within the counting period. Cn / 2 represents the number of revolutions of the motor. Based on the sampling frequency fc, the average motor speed can be calculated. Multiplying this by 60 gives the motor speed (unit: revolutions per minute).

[0051] The motor operating time Tm is obtained by testing using the following formula: Tm = (T Tn +T Bn The operating time of the motor can be calculated by dividing the cumulative number of samples by the sampling frequency.

[0052] Where: P G : Set air pressure threshold; P n : The air pressure value currently being read from the air chamber; fc: Sampling frequency.

[0053] The motor's operating mode was determined by testing the following steps:

[0054] First, let T1 be the working time of the product, T1 = Tm;

[0055] The second step is to calculate the cumulative number of times the read air pressure value does not change, TSN.

[0056] T Sn =P n -P n-1 T Sn =0; where P n The current air pressure value read in P. n-1 The air pressure value read from the last sampling;

[0057] The third step is to let T2 be the product's downtime; this is calculated using the following formula.

[0058] T2 = T Sn / fc(T2 <t g ), where: t g This is the maximum product pause time set according to the product model.

[0059] The fourth step is to compare the calculated T1 and T2 values ​​with the pre-stored mode values ​​to determine the product's operating mode. For example, T1:T2 = 2:1 indicates a shortwave mode; T1:T2 = 1:1 indicates a mediumwave mode; and T1:T2 = 1:3 indicates a longwave mode.

[0060] Preferably, in step S3, the set air pressure threshold P G The specific steps are as follows: read the air pressure value in the product's air chamber over a period of time, find the dividing point where the air pressure value changes from high to low or from low to high, and the average value of the air pressure value at multiple dividing points is the air pressure threshold. In step S3, if the output voltage does not change within a set time period, it means that the motor has stopped working.

[0061] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
