Description

Technical Field

[0001] This invention relates to the field of diaper technology, specifically to a device for testing the breathability of diapers. Background Technology

[0002] Currently, with changing consumption concepts and improved living standards, diapers have gradually become a daily necessity for infants and young children. The market is flooded with diaper brands, making the selection of a suitable diaper a challenge for consumers. When choosing diapers, consumers consider safety and cleanliness, as well as sufficient absorbency and good breathability. Breathable diapers greatly improve the comfort of infants and young children, effectively preventing skin allergies and diaper rash. Consumers often believe that thinner diapers are more breathable, but in actual use, the absorbent material inside the diaper may block the air channels after it absorbs moisture, reducing or even eliminating breathability.

[0003] In response, Chinese patent application number CN208109655U discloses a diaper breathability testing device, including a base with at least two parallel lower cavities on the base. Each lower cavity is connected to a pressure device. An upper cavity is provided on top of each lower cavity. A connected rubber gasket is provided at the upper end of the lower cavity and the lower end of the upper cavity. The front sidewalls of the lower and upper cavities are connected by fasteners, and the rear sidewalls of the lower and upper cavities are connected by hinges. The base, upper cavity, and lower cavity are all transparent. The device is simple to operate, provides clear observations, has a good sealing effect, and is not prone to air leakage. It can test at least two diapers simultaneously, making it easy for consumers to intuitively reflect the breathability of different diapers before and after absorbing water.

[0004] However, existing diaper breathability testing devices rely on adding liquid to the top of the diaper and observing the formation of bubbles to determine breathability, which is a crucial factor during diaper use. This method may result in diapers that cannot be used properly, thus increasing costs.

[0005] Therefore, in order to solve the above problems, a device for testing the breathability of diapers is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a device for testing the breathability of diapers, in order to solve the problem mentioned in the background art of the prior art where the breathability of diapers is a crucial factor during use. In existing devices, the breathability is determined by adding liquid to the top of the diaper and observing the generation of bubbles. This structure may result in the tested diapers being unusable, thereby increasing costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a diaper breathability testing device, comprising: a support leg and a worktable, the upper end of the support leg being provided with the worktable, the worktable being provided with a testing mechanism, the testing mechanism having an upper cavity, the upper cavity having rotating shafts on both sides, the rotating shafts having threaded rods, the threaded rods having threaded sleeves, and a fan being provided at the upper end of the upper cavity, the fan having a protective cover, and a positioning mechanism being provided on the worktable, the positioning mechanism having a lower cavity, the lower cavity having clamping plates on both sides, and a connecting tube being provided on one side of the lower cavity, the positioning mechanism being used to position the diaper, and the testing mechanism being used to test the diaper.

By setting this component, the diaper can be positioned by the positioning mechanism 3, and the diaper can be tested by the testing mechanism 4.

[0029] As a further step of the present invention, a pressure booster 34 is provided at one end of the connecting pipe 33. The pressure booster 34 is fixedly installed on the workbench 2 and is connected to the lower cavity 31 through the connecting pipe 33. By setting this component, gas can be transported to the lower cavity 31 through the connecting pipe 33 via the pressure booster 34.

[0030] As a further step of the present invention, a hinge 35 is fixedly installed on one side of the lower cavity 31, and the lower cavity 31 is connected to the upper cavity 41 through the hinge 35. The filter disc 36 is fixedly installed inside the lower cavity 31. By setting this component, the upper cavity 41 can be opened and closed by the action of the hinge 35.

[0031] As a further step of the present invention, a limiting disk 37 is fixedly installed in the middle of the filter disk 36, and a sealing ring 38 is detachably installed on the lower cavity 31. By setting this component, the gas can be filtered through the filter disk 36.

[0032] As a further step of the present invention, the upper cavity 41 is movably mounted on the lower cavity 31 via a hinge 35, and the rotating shaft 42 is fixedly mounted on the upper cavity 41. By setting this component, the threaded rod 43 can be moved via the rotating shaft 42.

[0033] As a further step of the present invention, one end of the threaded rod 43 is fixedly mounted on the rotating shaft 42, the threaded sleeve 44 is threadedly mounted on the threaded rod 43, the fan 45 is fixedly mounted on the upper cavity 41, and the protective cover 46 is fixedly mounted on the outside of the fan 45. By setting this component, the threaded rod 43 can be limited on the clamping plate 32 by the threaded sleeve 44 on the threaded rod 43.

[0035] Working principle: When the diaper breathability testing device is needed, simply support the device with the support leg 1, power it with the existing power supply, place the diaper in the lower cavity 31, and open and close the upper cavity 41 via the hinge 35. The threaded rod 43 on the bearing 42 is then engaged with the clamping plate 32, and the threaded rod 43 is fixed to the clamping plate 32 via the threaded sleeve 44, thus sealing the upper cavity 41 and lower cavity 31. This process can be achieved by sealing the cavity with the sealing ring 38. Then, the pressurizer 34 is activated to deliver gas to the lower cavity 3 through the connecting pipe 33. The gas is then filtered by the filter disc 36 before being delivered to the diaper. At this point, observe whether the fan 45 is rotated by the gas permeating the diaper. If the fan rotates, the diaper's breathability is good; otherwise, it is not. This completes the testing process.
