Description

Technical Field

[0001] This utility model relates to the technical field of atomizer testing equipment, and in particular to a device for fixing, timing, and alarming atomizer accelerated aging test. Background Technology

[0002] Nebulizers, as a commonly used medical device, are widely used in the treatment of respiratory diseases. Accelerated aging testing is a crucial step in the research and development and production of nebulizers, assessing product reliability and durability. Currently, nebulizers mainly consist of an atomizer and an atomizing cup, with the atomizer responsible for providing electrical power and controlling the atomization process.

[0003] In the prior art, atomizers are typically fixed using a specific support structure. For example, patent document WO2025139492A1 discloses a main unit and an atomizer, wherein the main unit includes a bottom shell, a cover, and a support. The support is located within a receiving cavity and has a receiving groove. The side wall of the receiving groove has an air inlet and an air outlet for mounting the atomizer. While this structure allows for the mounting of the atomizer, it does not consider the specific requirements of accelerated aging tests.

[0004] Regarding the monitoring function of atomizers, patent document CN212088086U discloses an electronic atomization device, including a battery rod and an atomizer. The battery rod is equipped with a weighing sensor and an alarm device. When the weighing sensor detects that the weight of the atomizer is less than a preset threshold, the control component controls the alarm device to sound an alarm. This technical solution mainly addresses the detection of insufficient e-liquid and does not cover comprehensive detection of atomizer malfunctions.

[0005] The existing technology has the following shortcomings: First, it lacks a dedicated fixing device suitable for accelerated aging tests of nebulizers, failing to meet the requirement that nebulizers cannot be placed upright and require a specific tilt angle; second, during the 58-day accelerated aging test, the nebulizer needs to be removed multiple times a day to replenish saline solution and be turned on for testing, and the existing technology lacks an effective timer reminder function, which can easily lead to testers forgetting the operation time points; third, the existing technology lacks an automatic detection and alarm mechanism for malfunctions of the nebulizer during the test, making it impossible to detect and record faults in a timely manner; fourth, the existing support structure is not convenient for testing multiple products simultaneously, reducing testing efficiency; finally, the existing devices generally lack a design that can withstand the conditions of high-temperature and high-humidity environmental chambers, failing to meet the special environmental requirements of accelerated aging tests. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the shortcomings of existing technologies in the accelerated aging test of atomizers, such as cumbersome operation, difficult placement, lack of timed reminders and abnormality detection functions.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] According to one aspect of this utility model, a device for fixing, timing, and alarming an atomizer during accelerated aging testing is provided, comprising: a support body having a plurality of atomizer receiving units, each atomizer receiving unit being an inclined slot matching the shape of the atomizer, the bottom of the slot having an atomizer fixing groove; an environmentally resistant shell covering the outside of the support body, made of a high-temperature and high-humidity resistant material; a timing control module integrated inside the shell, containing a built-in timer and a buzzer alarm; and a function detection module including electrode contacts located at the bottom of the slot for detecting the atomizer's on / off status.

[0009] Optionally, the tilt angle of the inclined slot is 15°-30°, and the slot is provided with an anti-slip silicone layer.

[0010] Optionally, the main body of the support is made of transparent material, and the outer shell has several transparent observation windows, each corresponding to one of the atomizer housing units of the main body of the support.

[0011] Optionally, the timing control module includes: a time setting unit for presetting the number of tests per day and the interval time; and a cycle triggering unit connected to a buzzer alarm and an indicator light.

[0012] Optionally, the cyclic triggering unit is connected to the wireless communication module for sending reminder signals to external terminals.

[0013] Optionally, the function detection module may further include a current detection circuit that monitors the atomizer's operating current via electrode contacts.

[0014] Optionally, the function detection module is connected to the anomaly recording unit. When an abnormal current is detected, it triggers an audible and visual alarm and stores the fault time point.

[0015] Optionally, the device also includes an environmental enclosure embedded mounting structure, including a magnetic base located at the bottom of the housing.

[0016] Optionally, the environmentally resistant housing is coated with a hydrophobic coating, and the internal circuitry is encapsulated using a sealing potting process.

[0017] The advantages of this invention are as follows: A specially designed support structure solves the fixation problem in accelerated aging tests of atomizers, allowing the atomizer to be stably placed in the environmental chamber; a timed reminder function ensures that testers remove the atomizer for functional testing on time, improving the standardization and accuracy of the test; an abnormal alarm function can promptly detect and record atomizer malfunctions, improving test reliability; the support can simultaneously fix multiple atomizer products, improving test efficiency; and the support material can withstand the high temperature and humidity environment of the environmental chamber, ensuring test stability and reliability. Compared with existing technologies, this invention specifically addresses the special needs of accelerated aging tests of atomizers, providing a comprehensive solution integrating fixation, timed reminders, and abnormal alarm functions, effectively solving several technical challenges faced by accelerated aging tests of atomizers in existing technologies.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] like Figure 1 and Figure 2 As shown, an atomizer accelerated aging test fixing, timing, and alarm device includes a support body, an environmental tolerance shell, a timing control module, and a function detection module.

[0025] The main body of the stand features multiple atomizer housing units, each a tilted slot that matches the shape of the atomizer. These tilted slots have an angle of 15°-30°, ensuring both stability and easy observation of the atomizer during placement. The inner wall of the slots has a non-slip silicone layer, enhancing friction between the atomizer and the slot and preventing slippage during testing. The bottom of the slots has a recessed atomizer fixing groove for precise positioning, ensuring stability during testing. The entire stand body is made of transparent material, allowing direct observation of the atomizer's operating status.

[0026] The environmentally resistant housing, made of high-temperature and high-humidity resistant materials, encases the main support structure, maintaining structural stability and functional integrity under harsh conditions during accelerated aging tests. A hydrophobic coating extends the device's lifespan. Several transparent observation windows are provided on the housing, each corresponding to a nebulizer housing unit on the main support, allowing for direct observation of the nebulizer's status. The internal circuitry of the environmentally resistant housing is encapsulated using a sealed potting process, further enhancing the circuitry's waterproof and moisture-proof performance.

[0027] The timing control module is integrated inside the housing, featuring a built-in timer and buzzer alarm. The module includes a time setting unit and a cycle triggering unit. The time setting unit presets the number of tests per day and the interval, allowing for flexible adjustment of the test frequency and duration according to different testing requirements. The cycle triggering unit connects to the buzzer alarm and indicator lights; when the preset time point is reached, it triggers an audible and visual alarm to remind the operator to check the atomizer status or perform corresponding operations. The cycle triggering unit also connects to a wireless communication module to send reminder signals to external terminals such as mobile phones and computers, enabling test personnel to be aware of the test status even when not on-site.

[0028] The functional detection module includes electrode contacts located at the bottom of the slot for detecting the atomizer's power-on / off status. When the atomizer is inserted into the slot, the electrode contacts contact the atomizer's power interface, forming a detection circuit. The functional detection module also includes a current detection circuit that monitors the atomizer's operating current via the electrode contacts. This current detection circuit can monitor current changes in the atomizer in real time during operation to determine if the atomizer is functioning correctly. The functional detection module is connected to an anomaly recording unit. When an abnormal current is detected, it triggers an audible and visual alarm and stores the fault time point for subsequent analysis of the atomizer malfunction cause and occurrence time.

[0029] In a preferred embodiment, the device further includes an embedded mounting structure within an environmental chamber, comprising a magnetic base located at the bottom of the housing. The magnetic base can firmly adhere to the metal surface inside the environmental chamber, ensuring the device remains in a stable position within the chamber and does not change position due to vibration or movement, thus ensuring the stability and consistency of the testing process.

[0030] When the device is in operation, the atomizer is first placed in the tilted slot, with the bottom of the atomizer fitting snugly against the fixing groove, and the electrode contacts making contact with the atomizer's power interface. The test frequency and time interval are set via the time setting unit, and the device begins operation. When the preset time point is reached, the cycle trigger unit activates the buzzer alarm and indicator light, and simultaneously sends a reminder signal to an external terminal. The operator checks the atomizer status or performs corresponding operations based on the reminder. During the test, the functional detection module continuously monitors the atomizer's current status; once an abnormality is detected, an alarm is immediately triggered and the fault time point is recorded. Throughout the entire test, the environmentally resistant casing protects the internal circuitry and structure from the effects of high temperature and high humidity, ensuring long-term stable operation of the device.

[0031] Example 2:

[0032] The accelerated aging test process and principle of the atomizer are as follows:

[0033] Test Objective: Accelerated aging testing involves placing the atomizer in a high-temperature environment and calculating the accelerated testing time based on parameters such as the accelerated testing model, acceleration factor, and nominal service life. During the accelerated aging test, the device is functionally tested daily to confirm it remains in good condition. The test results are observed to evaluate whether the atomizer has reached its standard service life.

[0034] Experimental Method: Based on the pre-set shelf life of the atomizer, the accelerated aging period under working conditions was calculated to be 58 days. The atomizer was accelerated aging for 3 hours at 40℃ and 80% humidity from Monday to Friday, and for 16.5 hours at 55℃ and 80% humidity. On Saturdays and Sundays, it was accelerated aging for 24 hours at 55℃ and 80% humidity.

[0035] After the accelerated aging test, the following tests were performed:

[0036] 1. The atomizer should have a clean appearance, uniform color, and no defects such as scratches, cracks, etc. The text and markings on the panel should be clearly visible.

[0037] 2. The atomizer plastic parts are free from bubbles, foaming, cracking, deformation, and overflow of filling material.

[0038] 3. The atomizer's control mechanism is securely and reliably installed, with no loose fasteners.

[0039] If the above test results meet the requirements, the rationality of the pre-set validity period is verified, and the product validity period is at least 2 years.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
