Description

Technical Field

[0001] This utility model relates to the field of noise detection technology, and more specifically, to a vacuum cleaner noise detection chamber. Background Technology

[0002] Vacuum cleaners are cleaning tools, mostly used indoors. Therefore, noise levels are often a consideration when choosing vacuum cleaners for indoor use.

[0003] Existing noise detection methods are mostly conducted in quiet environments at night. However, for devices that cannot be remotely controlled, these methods often require operators to manually turn the device on and off. During this process, operators will receive noise from the vacuum cleaner. When dealing with high-powered vacuum cleaners, frequent noise exposure can be inconvenient for operators.

[0004] Therefore, a new solution is needed to supplement the existing categories of noise detection products. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum cleaner noise detection chamber.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vacuum cleaner noise detection chamber, comprising a soundproof chamber and sound-absorbing material disposed on the inner wall of the soundproof chamber, a support net disposed in the soundproof chamber, a bearing plate fixedly disposed on the support net, and a vertical rod fixedly disposed on the bearing plate, two sets of clamps disposed at the end of the vertical rod away from the bearing plate, and a pressing element disposed on one set of clamps, a decibel meter disposed in the soundproof chamber, and a control device disposed outside the soundproof chamber, the control device being connected to the pressing element and the decibel meter by signal communication.

[0007] The present invention is further configured such that: the pressing component is an electric push rod and a sensor, both of which are movably mounted on the upright; the sensor detects pressure on the electric push rod; and the control device receives signals from the sensor and the electric push rod and controls the electric push rod.

[0008] The present invention is further configured such that the supporting plate is configured as multiple pieces that can be arranged in a mutually complementary manner.

[0009] The present invention is further configured such that: the support plate has multiple through holes, and the through holes of adjacent support plates are interconnected, and a connecting rod is slidably provided in the through hole area of ​​the support plate.

[0010] The present invention is further configured such that the cross-section of the connecting rod is elliptical, and the connecting rod is capable of abutting against the inner wall of the through hole of the bearing plate.

[0011] The present invention is further configured such that the connecting rod is made of plastic material.

[0012] In summary, this utility model has the following beneficial effects: after the operator has adjusted the clamp and pressing parts, the test equipment can be controlled from outside the soundproof room, and the operator can test the noise level from outside the soundproof room, thus minimizing noise interference.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A vacuum cleaner noise testing chamber, such as Figures 1-4As shown, the system includes a soundproof chamber 1 and sound-absorbing material 2 installed on the inner wall of the soundproof chamber 1. A support mesh 3 is installed inside the soundproof chamber 1, and a support plate 4 is fixedly installed on the support mesh 3. A vertical rod 5 is fixedly installed on the support plate 4. Two sets of clamps 8 are installed at the end of the vertical rod 5 away from the support plate 4, and a pressing element is installed on one set of clamps 8. When items and the support plate 4 are inside the soundproof chamber 1, they are placed on the support mesh 3 to prevent the items from damaging the sound-absorbing material 2 on the inner wall of the soundproof chamber 1. The uprights 5 on the carrier plate 4 are used to fix the vacuum cleaner. The pressing mechanism is used to control the vacuum cleaner's power button. Different models of vacuum cleaners have different structures and switch positions. The clamp 8 is used to hold the handle of some vacuum cleaners with power buttons, thus allowing the pressing mechanism to operate the vacuum cleaner on and off. It also facilitates changing the position of the pressing mechanism. A decibel meter 6 is installed inside the soundproof chamber 1, and a control device 7 is installed outside the soundproof chamber 1. 7 establishes signal communication with the pressing component and the decibel meter 6 respectively. The decibel meter 6 measures the noise level, and the measured noise value is transmitted to the control device 7 and recorded. Operators outside the noise testing room can operate the pressing component through the control device 7. The pressing component consists of an electric push rod 9 and a sensor 10. Both the electric push rod 9 and the sensor 10 are movably mounted on the upright 5. The sensor 10 detects the pressure of the electric push rod 9. The control device 7 receives signals from the sensor 10 and the electric push rod 9 and controls the electric push rod 9. For some devices that cannot be operated by remote control, the electric push rod 9 is used to push the vacuum cleaner button. The sensor 10 calculates the force of the electric push rod 9 after its extended part comes into contact with the vacuum cleaner. After reaching a threshold, the sensor controls the electric push rod 9 to return, thus forming a single press of the button on the vacuum cleaner. The threshold of the sensor 10 is calculated in advance by the tester to ensure that the electric push rod 9 can press the vacuum cleaner.

[0020] The support plates 4 are configured as multiple plates that can be arranged in a mutually complementary manner. The operator can set the number of support plates 4 as required to match the area of ​​the support plates 4 with the vacuum cleaner, which helps to reduce noise rebound and make noise measurement more accurate. The upright rod 5 and the pressing component are all set on one of the support plates 4. The support plates 4 have multiple through holes 12, and the through holes 12 of adjacent support plates 4 are interconnected. Connecting rods 13 are slidably arranged in the through hole 12 area of ​​the support plates 4. The through holes 12 on the support plates 4 are designed for the connecting rods 13 to pass through, thereby allowing multiple support plates 4 to be arranged in a mutually complementary manner. After the positions are determined, the positions of the support plates 4 can be locked by the connecting rod 13, preventing unnecessary movement of the support plates 4 when people walk or move the vacuum cleaner. The cross-section of the connecting rod 13 is elliptical, and the connecting rod 13 can abut against the inner wall of the through hole 12 of the support plate 4. The connecting rod 13 is made of plastic material. After the connecting rod 13 is installed in the support plate 4, the operator can rotate the connecting rod 13 to form a locking between the connecting rod 13 and the through hole 12 of the support plate 4, thereby fixing the two support plates 4 to each other.
