Description

TECHNICAL FIELD

[0001] The utility model relates to the field of domestic appliance noise test, concretely relates to a water pick noise test load. BACKGROUND

[0002] GB / T 19606 "domestic and similar use appliance noise limit" is the domestic appliance noise national standard, and the approximate content of its "appendix B" oral hygiene appliance noise test method is as follows:

[0003] "For the oral irrigator which is placed on the table during normal use: place its main machine on the rubber mat floor, and use a clamp to clamp the nozzle hand holding part, so that the nozzle bottom end is 25cm above the main machine upper end and runs in a horizontal state. For other types of oral irrigators, as well as electric toothbrushes, use a clamp to clamp the appliance hand holding part, so that the bottom end is 25cm above the ground and runs in a horizontal state. The clamp base is placed on a 5mm-10mm thick elastic rubber pad, and it is ensured that the use of the clamp has no effect on noise test."

[0004] For the noise test of oral hygiene appliances, the noise test of the water pick is involved. In the above-mentioned noise test method of oral hygiene appliances, the test load of the water pick is not specified. According to the test requirements, the water pick to be tested is placed in a semi-anechoic chamber during testing, and then direct testing is performed. This will have the following disadvantages:

[0005] 1. During the test, the water pick sprays water column horizontally forward when working, and the spraying distance is about 2-3m, and the end of the water column spray is in a scattering state. This will easily spray and scatter onto the sound-absorbing cotton of the wall of the semi-anechoic chamber and the test sensor, causing damage to the sound-absorbing cotton wall and the test sensor and affecting the test.

[0006] 2. The water pick has no corresponding load, and the water column is directly sprayed outward, which makes the sound of water spraying obvious, affecting the test of the sound of the water pick itself running, and this also has certain differences from actual use. When actually used, the nozzle of the water pick is contained in the user's mouth, and there is no obvious sound of water spraying.

[0007] Therefore, the present inventors set up a corresponding noise test load for the noise test of the water pick, which can collect the water column sprayed when the water pick works and eliminate the sound of water spraying as much as possible. UTILITY MODEL CONTENT

[0008] The utility model aims to provide a water pick noise test load which can avoid the water column sprayed by the water pick from spraying onto the sound-absorbing cotton of the wall of the semi-anechoic chamber and the test sensor during testing, and the noise test result is more in line with the actual use.

[0009] The utility model discloses a technical scheme that follows realizes the purpose:

[0010] A oral irrigator noise test load, characterized in that: including support, load body and water jar, load body installs on the support, the inside of load body is equipped with the chamber for simulating oral cavity, the front of chamber is equipped with the insertion port for the nozzle of oral irrigator inserts, is equipped with a row of the baffle for simulating tooth in the chamber, the bottom of chamber is equipped with the drain, and the drain is connected with water jar through water pipe.

[0011] The utility model further discloses a technical scheme: the insertion port is circular, and the inner ring of insertion port is equipped with soft rubber strip.

[0012] The utility model further discloses a technical scheme: be equipped with the lifting frame that can adjust height along the up and down of support, and load body is fixed and is established on the lifting frame.

[0013] The utility model further discloses a technical scheme: the baffle is arranged in arc shape, thereby simulating tooth shape.

[0014] The utility model further discloses a technical scheme: the support includes base and straight pole, and straight pole is vertically fixed on the upper surface of base.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] When testing, the nozzle of oral irrigator will be inserted into the chamber of load body of the utility model, simulates oral cavity through load body, as the load of oral irrigator, and the water column that oral irrigator sprays will be sprayed into the chamber of load body, and is discharged to water jar through drain, realizes the collection of water. In the testing process, do not need to worry about that the water column sprays on the sound absorption cotton of the wall surface of half sound attenuation chamber and test sensor, and because the nozzle is in load body, the sound of water spraying is also basically eliminated, in the noise test process, more close to actual use situation, and the noise test result is more in line with the noise size under actual use state.
