Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, and in particular relates to a testing device for a vacuum cleaner water strip. Background Technology

[0002] The water spray nozzle is an important component of a wet vacuum cleaner. It is mainly used to spray water or cleaning solution during the cleaning process to achieve better cleaning results and reduce dust flying.

[0003] Current testing methods for vacuum cleaner nozzle strips have significant shortcomings in their positioning structures. For nozzle strips with complex nozzle layouts or non-standard shapes, existing positioning devices may not provide stable fixation, leading to nozzle displacement or vibration during testing and affecting the accuracy and reliability of the test. This positioning problem not only increases the difficulty of testing but may also result in poor repeatability of test results, failing to meet the needs of large-scale production and quality control. Utility Model Content

[0004] The purpose of this invention is to address the issue that existing positioning devices may not provide stable fixation for water strips with complex nozzle layouts or non-standard shapes, leading to displacement or vibration of the water strip during testing, thus affecting the accuracy and reliability of the test. This positioning problem not only increases the difficulty of testing but may also result in poor repeatability of test results, failing to meet the needs of large-scale production and quality control. Therefore, this invention proposes a testing device for vacuum cleaner water strips.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a testing device for a vacuum cleaner water strip, comprising:

[0006] The workbench is equipped with several linear motors, a support plate, and an airtightness tester. A telescopic cylinder is mounted on the support plate, and a movable plate is located at the bottom of the telescopic cylinder. Several positioning components are mounted on the movable plate.

[0007] The water outlet bar positioning fixture is slidably connected to the linear motor at its bottom, and several positioning components are located directly above the water outlet bar positioning fixture.

[0008] As a further description of the above technical solution:

[0009] The water outlet positioning fixture includes a sliding plate and a positioning platform. The positioning platform is connected to the sliding plate, the bottom of the sliding plate is connected to the linear motor, and a positioning groove is provided on the positioning platform.

[0010] As a further description of the above technical solution:

[0011] The workbench is equipped with a waste trough, and a waste bin is placed inside the waste trough. The waste trough is located between the two linear motors.

[0012] As a further description of the above technical solution:

[0013] The support plate is provided with a guide rail, and the movable plate is provided with a guide groove, which is slidably connected to the guide rail.

[0014] As a further description of the above technical solution:

[0015] The worktable is provided with a limiting groove, and the bottom of both sides of the sliding plate is provided with limiting blocks, which are slidably connected in the limiting groove.

[0016] As a further description of the above technical solution:

[0017] The air tightness tester is equipped with an inflation port and an air outlet port.

[0018] As a further description of the above technical solution:

[0019] The positioning element includes a stud and an abutment frustum, the stud passing through the movable plate and connected to the abutment frustum.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. In this utility model, by setting several positioning components on the moving plate, the positioning components include studs and abutment truncated cones. The studs pass through the moving plate and connect to the abutment truncated cones, and the abutment truncated cones abut against the water outlet strip. When encountering water outlet strips of different shapes or complex structures, several connecting holes are set on the moving plate, and several positioning components can be installed on the moving plate at intervals according to the shape of the vacuum cleaner water outlet strip, thereby avoiding conflicts between protrusions or test inlets on the water outlet strip. This structure can be used to position water outlet strips of different structures and improve test accuracy.

[0022] 2. In this utility model, the water outlet positioning fixture is slidably connected to a linear motor, and the positioning component is connected to a moving plate. The moving plate is continuously raised and lowered under the drive of a telescopic cylinder. When testing is required, the vacuum cleaner water outlet strip is placed in the positioning groove, and the telescopic cylinder drives the moving plate to move down, so that the abutting platform abuts against the top of the vacuum cleaner water outlet strip. The interfaces on the water outlet strip are respectively connected to the inflation interface and the air outlet interface of the air tightness tester. The air tightness tester is used to inflate the water outlet strip and observe the change in air pressure inside, thereby testing whether the water outlet strip meets the standard.

[0023] 3. In this utility model, by setting up a waste bin, when the test fails, it can be directly put into the waste bin for recycling. Attached Figure Description
