Description

Technical Field

[0001] The utility model relates to the technical field of facial mask testing, in particular to a water absorption tester. Background Art

[0002] Moisturizing properties and water absorption are important metrics for facial masks. Therefore, when developing facial masks, the water absorption of the membrane fabric must be tested. This test typically involves dripping essence onto the membrane fabric and observing whether it drips from a suspended cotton cloth. While this method can measure the moisture absorption of the membrane fabric based on the amount of essence dripped in, the adsorption capacity of the membrane at a certain location reaches saturation during the dripping process, resulting in dripping. Consequently, existing methods for testing water absorption have low accuracy. Utility Model Content

[0003] The utility model provides a water absorption tester to solve the above-mentioned deficiencies in the prior art and the problem of low accuracy in detecting the moisture retention of membrane cloth, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A water absorption tester includes a base plate, a lower cover is placed on the base plate, a connecting tube is provided on the lower cover, and a conical bucket is provided at the upper end of the connecting tube. The conical bucket and other components are used to receive dripping essence and facilitate the weighing of the dripping amount, so as to accurately know the moisture absorption effect of the membrane cloth.

[0006] A pair of vertical arms are mounted on the base plate. The upper ends of the vertical arms are openly formed with grooves. A rectangular block is positioned within the grooves. Limiting plates are positioned on the inner and outer sides of the rectangular block. The vertical arms are positioned on the inner and outer sides of the limiting plates. An external wire rod is mounted on the rectangular block. An inner plate is pivotally mounted on the inner end of the external wire rod. A clamp is mounted on the inner plate. An external arm is positioned on the inner plate. The external arm passes through the grooves. An L-shaped arm is positioned within the grooves. A rectangular frame is positioned on the inner end of the L-shaped arm. The clamp can clamp the ends of the membrane cloth. The lower end of the rectangular frame acts on the membrane cloth. During testing, a certain amount of essence can be dropped into the rectangular frame. The essence will then be absorbed by the membrane cloth. When saturated, the essence will drip into a conical bucket. The conical bucket can then be weighed to determine the amount of dripping. The ratio of the dripping amount to the total amount can be used to determine the moisture absorption properties of the membrane cloth.

[0007] Furthermore, an end cap is provided at the outer end of the outer drawing rod to facilitate the rotation of the outer drawing rod.

[0008] Furthermore, the clamp includes an inner convex plate arranged on the inner wall of the inner plate, a pair of vertical plates are provided on the inner convex plate, and rotating columns are respectively rotatably provided at the upper and lower ends of the vertical plates, and a convex pressure plate is provided on the outer periphery of the rotating column. A pair of vertical guide holes are respectively opened at the two ends of the inner plate, and screws are passed through the vertical guide holes. The inner ends of the screws are provided with clamping plates, which are located on the upper and lower sides of the inner convex plate, and the outer ends of the convex pressure plates act on the outer wall of the clamping plates. When clamping, the rotating column can be rotated to make the inner pressure plate act on the clamping plate, and then the two ends of the membrane cloth are clamped by the clamping plates.

[0009] Furthermore, a holding rod is provided on the outer periphery of the rotating column to facilitate the rotation of the rotating column.

[0010] Furthermore, in order to ensure the stability of the rectangular frame after placement, a pair of transverse side plates are provided at the outer ends of the L-shaped arms, and the transverse side plates are located at the inner and outer sides of the vertical arms.

[0011] The advantages of the above technical solution are:

[0012] The utility model can accurately and objectively reflect the moisture absorption performance of the membrane cloth and improve the accuracy of detection. BRIEF DESCRIPTION OF THE DRAWINGS
