Ambient Temperature	27.4 °C
Initial State	Full charge (满电)
Run Condition	Continuous operation from power-on to battery exhaustion
Data Collected	Temperature change data sampled throughout discharge cycle (see sibling sheet: 温升变化数据)
Test Photos	Internal wiring (内部接线); in-operation thermal image (温升运行中)

Test Procedure

Pre-test: Confirm sample battery is fully charged. Record ambient temperature (27.4 °C). Prepare temperature measurement equipment and assign sample IDs (4#, 5#).
Setup: Place samples in ambient environment. Attach or position temperature probes at three measurement points: motor, battery, and air outlet.
Operation: Power on sample at room temperature in full-charge state. Allow continuous operation without interruption.
Data Collection: Record temperature readings at each measurement point throughout the run. Capture thermal images during operation (温升运行中).
End Condition: Test concludes when battery is fully depleted and device shuts off.
Post-test: Record peak temperatures and calculate temperature rise (K) for each measurement point by subtracting ambient temperature from the peak reading.
Acceptance Criteria: Evaluate performance stability of temperature variation. Results in this report are classified as For Reference Only (供参考) — no pass/fail threshold applied.

Test Data & Results

Sample ID	Measurement Item	Motor (°C / K)	Battery (°C / K)	Air Outlet (°C / K)	Ambient Temp (°C)
HB1-4#	Peak Temperature (°C)	43.1	34.2	32.4	27.4
HB1-4#	Temperature Rise (K)	15.7	6.8	5.0	—
HB1-5#	Peak Temperature (°C)	38.4	32.4	32.6	27.4
HB1-5#	Temperature Rise (K)	11.0	5.0	5.2	—

Observations: HB1-4# recorded a higher motor peak temperature (43.1 °C, +15.7 K) compared to HB1-5# (38.4 °C, +11.0 K), a difference of 4.7 K at the motor point. Battery and air outlet temperature rises were comparable across both samples, all remaining below 7 K above ambient. Detailed time-series temperature change data is available in the companion sheet (温升变化数据). Note from report: test data is on the next sheet.

Frequently Asked Questions

What does the HB1 air pump thermal rise test measure?

The test measures peak temperatures and temperature rise (in Kelvin) at three points — the motor, battery, and air outlet — while the HB1 runs continuously from a full charge until the battery is depleted. This evaluates thermal stability and heat dissipation performance under a realistic worst-case discharge scenario.

What were the highest temperatures recorded for the HB1 during thermal testing?

With an ambient temperature of 27.4 °C, the motor on sample HB1-4# reached the highest recorded temperature of 43.1 °C (a rise of 15.7 K). Sample HB1-5# peaked at 38.4 °C at the motor (rise of 11.0 K). Battery and air outlet temperatures on both samples rose less than 7 K above ambient.

Did the HB1 pass the thermal rise test?

This test cycle was classified as For Reference Only (供参考) — no formal pass/fail threshold was applied. The data is intended for engineering evaluation of thermal stability and heat dissipation rather than compliance certification.

Where can I find the full time-series temperature data for the HB1 thermal test?

The complete temperature change data recorded throughout the discharge cycle is available in the companion sheet 温升变化数据 from the same Excel workbook (HB1吹气泵-温升报告-2025.7.24.xlsx). A cross-linked article covering that dataset is listed in the Related Products section below.
