Description

Technical Field

[0001] The utility model relates to the production and processing field of water flossers, in particular to an operating life tester for a pulse water flow water flosser. Background Art

[0002] The core components of the air-powered pulse water water flosser are an air pump, a solenoid valve and a silicone sheet. During use, the air pump is used to inflate the silicone sheet, causing the elastic bulge of the silicone sheet to deform and squeeze from a downward concave state to an upward convex state. Then, the piston column arranged on the elastic bulge instantly pushes the water inside the column when the elastic bulge is deformed, causing the water to generate instantaneous high pressure and spray out of the nozzle in the form of pulses, thereby achieving the purpose of flushing. After the water inside the column is sprayed out, the solenoid valve opens, the air pressure of the silicone sheet is released, and the silicone sheet returns to its initial state under the action of its elasticity. Therefore, In order to ensure the service life of the pulse water irrigator, the air pump, solenoid valve and silicone sheet need to be tested for operation. To achieve the purpose of the test, the industry standard requires that the air pump, solenoid valve and silicone sheet be tested for up to 250,000 cycles, from the air pump to the pressurization of the silicone sheet, and the solenoid valve to the pressure relief of the silicone sheet. If the product engineering prototype is used for testing, the air pump, solenoid valve and silicone sheet need to be assembled on the internal bracket of the oral irrigator. The assembly is troublesome, and the test process requires power replenishment and the product PCBA cannot work for a long time, making it difficult to achieve the purpose of the test for the product's service life. Utility Model Content

[0003] The utility model aims to provide a pulse water flow water irrigator operating life tester, by quickly integrating the core components of the water irrigator, an air pump, a solenoid valve and a silicone sheet on the tester, and controlling the air pump to pressurize the silicone sheet and the solenoid valve to release the pressure on the silicone sheet through the tester to perform a cycle test, thereby avoiding the problem of the life test of the water irrigator needing to be assembled on an internal bracket, and avoiding the problem of the need for power replenishment during the test process and the product PCBA being unable to work for a long time, thereby solving the life test of the pulse water flow water irrigator.

[0004] In view of this, the technical solution provided by the utility model is: a pulse water flow water flosser operation life tester, including a power socket, a table panel is provided on the upper part of the power socket, and the table panel is provided with two groups of test stations arranged opposite to each other, each group of test stations includes a silicone sheet fixing plate and a cylinder frame, and a row of multiple ventilation grooves for positioning the silicone sheet are provided on the silicone sheet fixing plate, and a clamping cylinder is provided on the cylinder frame, and a pressing plate is provided at the end of the telescopic rod of the clamping cylinder, and the pressing plate is movable above the silicone sheet fixing plate, and a bulging groove corresponding to the ventilation groove is provided on the pressing plate, and the silicone sheet positioned on the ventilation groove is compressed and sealed by the upper part of the pressing plate by the clamping cylinder, and the table panel is provided with multiple A positioning groove for fixing the solenoid valve, the positioning groove corresponds one-to-one with the ventilation groove, the table panel is provided with an air pump seat on one side of the silicone sheet fixing plate, the air pump seat is provided with a plurality of plug holes for plugging in the air pump, the plug holes correspond one-to-one with the ventilation groove, the side wall of the ventilation groove is provided with a pair of air guide tubes, one of the air guide tubes is used to connect the solenoid valve, and one of the air guide tubes is used to connect the air pump, after the solenoid valve and the air pump are connected to the ventilation groove through the air guide tube, the air pump is turned on to blow and press the ventilation groove, so that the elastic bulge of the silicone sheet changes from a downward concave state to an upward convex state, and then the silicone sheet is elastically restored to a downward concave state through the deflation of the solenoid valve, thereby realizing the operation test of the solenoid valve, the air pump and the silicone sheet.

[0005] Furthermore, the bulge groove is in a spherical arc shape. When the silicone sheet changes from a downward concave state to an upward convex state, the spherical arc shape of the bulge groove can completely fit the elastic bulge of the silicone sheet after it is completely deformed, thereby preventing the silicone sheet from being deformed too much.

[0006] Furthermore, a piston post hole corresponding to the piston post is provided at the top of the spherical arc of the bulge groove, and the piston post hole and the piston post are clearance-matched. The piston post hole limits the activity of the piston post, thereby preventing the silicone sheet from twisting during the elastic deformation process.

[0007] Furthermore, the ventilation groove is provided with a top column at the bottom center thereof, and the height of the top column protruding from the bottom thereof is lower than the opening surface of the ventilation groove. By providing the top column, the elastic bulge of the silicone sheet in the initial state positioned on the ventilation groove can be supported by the top column, thereby preventing the silicone sheet from transitionally deforming when returning to the downward concave state when the electromagnetic valve deflates the ventilation groove.

[0008] Furthermore, the number of the ventilation grooves is set to 3-8.

[0021] The following is a brief description of the implementation of the present utility model in conjunction with the accompanying drawings.

[0022] The core components of the air-powered pulse water water flosser include an air pump 7, a solenoid valve 6 and a silicone sheet 8. The air pump 7 and the solenoid valve 6 are common product structures. The air pump 7 is used to inflate and pressurize the silicone sheet 8, and the solenoid valve 6 is used to release the pressure after the silicone sheet 8 is inflated and pressurized. The silicone sheet 8 is integrally injection molded. Its structure is as shown in FIG. Figure 4 , Figure 5 The silicone sheet 8 includes a skirt 81 for sealing connection, an elastic bulge 82 is arranged in the center of the silicone sheet 8, and a protruding piston column 83 is arranged in the center of the elastic bulge 82. When the silicone sheet 8 is in the initial state, the elastic bulge 83 is concave downward. When the elastic bulge 82 of the silicone sheet 8 is subjected to pressure, the elastic bulge 82 is lifted up and then becomes an upward convex shape. Therefore, the piston column 83 of the silicone sheet 8 instantly pushes the water inside the pipe column during the elastic change of the elastic bulge 82, so that the water generates instantaneous high pressure and is sprayed out of the nozzle in the form of pulses, thereby achieving the purpose of flushing teeth.
