Description

Technical Field

[0001] This invention relates to a vacuum cleaner performance testing system, and more particularly to a system for testing the allergen removal rate of a vacuum cleaner. Background Technology

[0002] Vacuum cleaners are one of the most commonly used household cleaning appliances. In daily use, they are primarily used to clean dust and dirt from surfaces such as floors and carpets. However, due to the dense pile of carpets, dust and allergens easily get trapped inside, making them difficult to clean thoroughly. This makes the dust and allergens contained in carpets a potential source of air pollution. To address this issue, some vacuum cleaners on the market have made improvements in adsorbing dust and allergens, but the allergen protection functions of these products still need further refinement and validation.

[0003] Developing a system for testing the allergen removal rate of vacuum cleaners is urgently needed to address the aforementioned issues. This system should be able to assess the effectiveness of vacuum cleaners in removing dust and allergens from carpets, furniture, and other interior surfaces, providing consumers with more comprehensive and accurate product information. It should also encourage vacuum cleaner manufacturers to improve and enhance the allergen protection capabilities of their products, ultimately reducing air pollution and the occurrence of allergies.

[0031] This technical solution provides a system for testing carpet adsorption and anti-allergy performance to evaluate the performance of existing vacuum cleaners. The system utilizes a sampling component to collect dust and allergen-laden particles from carpets and then uses an antigen reagent kit to test the sampled filter paper. This assesses the vacuum cleaner's adsorption and anti-allergy performance, providing consumers with a reference for choosing the best vacuum cleaner. The introduction of this technical solution is expected to further improve the adsorption effect and allergen protection function of vacuum cleaners, increasing consumer trust and purchase rates.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0033] The system for testing the allergen removal rate of a vacuum cleaner in this invention includes a test chamber 1, a test carpet 2, an allergen distribution component, a test transport cart, and a test sampling component, as detailed below. Figures 1 to 3 The volume of test chamber 1 is 25 to 60 cubic meters, and a door 16 that can be opened and closed is provided on one side of test chamber 1.

[0034] The test carpet 2 is placed in the test chamber 1; the allergen distribution component is placed on the test chamber 1 to evenly distribute allergen dust onto the test carpet 2. The allergen dust consists of pre-prepared test dust and allergen powder.

[0035] In this technical solution, to simulate a real dust and allergen dust environment, test dust and allergen dust need to be pre-configured. The specific configuration process is as follows:

[0036] Preparation of test dust: Dust samples from different sources are collected and processed through screening, drying, and sealing to obtain pure, impurity-free dust samples. The test dust must meet international standards to ensure the accuracy and repeatability of its particle size distribution and chemical composition. During testing, the prepared test dust is sprayed onto the surface of the test carpet to simulate real dust content.

[0037] Preparation of allergen dust: Allergen dust samples from different sources, such as pollen and dust mites, are collected and processed through screening, drying, and sealing to obtain pure, impurity-free allergen dust samples. The type and particle size of the allergen dust must meet the requirements of the corresponding allergen test. During the test, the prepared allergen dust is sprayed onto the surface of the test carpet to simulate the actual allergen dust content.

[0038] In summary, the dust and allergen dust used for testing require strict control over collection, preparation, screening, drying, and sealing to ensure the accuracy and repeatability of their particle size distribution and chemical composition. Only in this way can the actual dust and allergen dust environment be simulated and used to test the adsorption effect and anti-allergy performance of vacuum cleaners.

[0039] A test transport cart is located inside the test chamber 1 and is used to transport the vacuum cleaner 4 to be tested. A test sampling component is mounted on the test transport cart and is used to sample the test carpet 2 after the vacuum cleaner 4 has absorbed the air. UWB base stations 3 are located at the four corners of the test chamber 1. The test transport cart is equipped with UWB tags 14 that match the UWB base stations 3. The test carpet 2 is fixed to the floor of the test chamber 1 using clips 5.

[0040] During actual runtime:

[0041] First, by tracking the real-time position and trajectory of the test vehicle using UWB technology, the motion controller can precisely control the Mecanum wheels, thereby enabling fine-tuning and control of the test vehicle's direction, speed, and trajectory. The motion controller uses a microcontroller or one of the following processor architectures: x86, ARM, or RISC-V.

[0042] During the test, the test carpet was secured to the floor of the test chamber with clips, and the test transport trolley moved automatically within the chamber. When the position of the test transport trolley changed, the motion controller received the updated trolley position information under the signal of the UWB base station and adjusted the Mecanum wheels in real time to achieve full adhesion of the test carpet 2.

[0043] The motion controller can also adjust and correct the trajectory of the test vehicle in the test chamber in real time based on feedback signals. If there is a problem with the contact between the test vehicle and the carpet surface or if the movement of the vehicle is abnormal, the motion controller will use its feedback control algorithm to make real-time adjustments and corrections to ensure that the test vehicle can move along the predetermined trajectory and achieve full coverage adsorption of the carpet area.

[0044] The allergen distribution assembly includes a pulse pump 6, a feed pipe 7 connected to the pulse pump 6, and a nozzle 8 located at the end of the feed pipe 7. The end of the feed pipe 7 away from the nozzle 8 is provided with a feeding port 9, and the feeding port 9 is provided with a feeding cap.

[0045] The nozzle 8 has a trapezoidal cross-section, and the area of ​​the lower surface of the nozzle 8 is 3 to 20 times that of the feed pipe 7. The lower surface of the nozzle 8 is provided with multiple sieve holes, and allergen dust is flushed out of the nozzle 8 by the pulse airflow output by the pulse pump 6.

[0046] The test transport trolley includes a trolley body 9 and an elastic clamping assembly disposed on the trolley body 9; the test sampling assembly is disposed on the trolley body 9. The elastic clamping assembly includes a fixing block 10 and a pressure plate 11 disposed on the trolley body 9. The fixing block 10 has a through hole, and a spring is disposed in the through hole. One end of the spring is connected to the inner wall of the through hole. The pressure plate 11 is connected to the other end of the spring. One end of the pressure plate 11 is provided with a rubber pad. The pressure plate 11 achieves the clamping of the vacuum cleaner 4 rod part through the rubber pad.

[0047] Two pairs of elastic clamping components are provided, which respectively clamp the vacuum cleaner 4 at two points on the handle, position the vacuum cleaner 4, and allow the suction part of the vacuum cleaner 4 to slide along the ground. The test sampling component includes a suction pump 13, a suction hood 12 connected to the suction pump 13 through a suction pipe, and a filter box 15 located at the suction inlet of the suction pump 13, wherein the filter box 15 contains sampling filter paper.

[0048] In this technical solution, the test sampling component is a device mainly used to collect dust and allergen dust on the carpet. Its specific working principle is as follows:

[0049] The suction pump 13 is the main suction device, used to suck up dust and allergen dust from the carpet surface and draw them into the suction hood 12.

[0050] The inhalation mask 12 is the main part of the sampling assembly. It contains sampling filter paper to filter and collect inhaled dust and allergen dust.

[0051] While the suction pump 13 is drawing in air, dust and allergen dust in the air are drawn into the suction hood 12, filtered by the filter paper, and the dust and allergen dust are collected on the sampling filter paper.

[0052] The filter box 15 serves as a protective device for the sampling filter paper, preventing dust and allergen dust from entering the suction pump 13 and affecting its service life.

[0053] After sampling, the collected filter paper is removed and tested using a dedicated antigen kit. The specific testing method can be selected based on the different allergens, such as rapid immunological reagent testing methods.

[0054] In summary, the testing sampling component is a crucial part for collecting dust and allergen particles from carpets. Through the coordinated work of multiple components, including a suction pump, sampling hood, filter cartridge, and sampling filter paper, it collects and stores sampling data. Subsequent testing of the sampling filter paper allows for the evaluation of the vacuum cleaner's filtration efficiency and the dust and allergen content on the carpet surface, thereby determining the vacuum cleaner's adsorption capacity and anti-allergy performance, such as its allergen removal rate.

It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
