Description

A fabric breathability demonstration device Technical Field

[0001] This utility model relates to a fabric function display device, belonging to the technical field of demonstration tools. Background Technology

[0002] Whether a fabric is breathable affects the comfort of clothing. Consumers often lack a direct understanding of fabric breathability when purchasing clothing, thus requiring a device to demonstrate this function. Current technology typically involves nesting a cylindrical object inside a cup, with the bottom of the cylindrical object wrapped with fabric. The breathability is then demonstrated by observing whether moisture in the cup can permeate the fabric into the cylindrical object. However, this method lacks a direct visual comparison and is inconvenient to operate. Summary of the Invention

[0003] In view of the above-mentioned defects in the prior art, the present invention aims to provide a fabric breathability display device to solve the problems of lack of breathability comparison and low ease of operation of the display device.

[0004] The technical solution of this utility model is as follows: A fabric breathability display device includes a base, a first lower display cylinder, a second lower display cylinder, a first upper display cylinder, and a second upper display cylinder. A water vapor generator is provided inside the base. The first lower display cylinder and the second lower display cylinder are arranged side by side on the base. The lower ends of the first lower display cylinder and the second lower display cylinder are connected to the base. The water vapor generated by the water vapor generator enters through the lower ends of the first lower display cylinder and the second lower display cylinder. The first upper display cylinder is stacked on top of the first lower display cylinder, and the second upper display cylinder is stacked on top of the second lower display cylinder.

[0005] Furthermore, in order to improve the stability of the device during display, the first upper display tube and the first lower display tube are connected by a snap-fit ​​connection, and the second upper display tube and the second lower display tube are connected by a snap-fit ​​connection.

[0006] Furthermore, the latch is a quick-release latch.

[0007] Furthermore, in order to improve the ease of operation while maintaining aesthetics, annular support plates are provided at the upper end of the first lower display tube, the upper end of the second lower display tube, the lower end of the first upper display tube, and the lower end of the second upper display tube.

[0008] Furthermore, the first lower display tube, the second lower display tube, the first upper display tube, and the second upper display tube are all transparent.

[0009] Furthermore, the base is connected to the first lower display tube and the base is connected to the second lower display tube via an airflow transition chamber. The airflow transition chamber is provided with a water vapor channel connecting the first lower display tube and the base, the second lower display tube and the base. An observable impeller is rotatably installed in the water vapor channel.

[0010] Furthermore, lighting devices are provided on the first and second upper display tubes.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] This invention features two lower display tubes arranged side-by-side on a base, through which water vapor rises, facilitating the comparative display of fabrics with different breathability properties. The upper and lower display tubes are stacked, and the fabric is fixed between them by joining the two tubes, making the operation convenient. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments, but this is not intended to limit the present invention.

[0018] Example 1, referring to Figures 1 and 2, describes a fabric breathability display device, including a base 100, a first lower display cylinder 101, a second lower display cylinder 102, a first upper display cylinder 103, and a second upper display cylinder 104. A water vapor generator 105 is installed inside the base 100, generating water vapor for display purposes. The water vapor generator 105 and its associated water storage chamber are fixedly installed in the base 100.

[0019] Two display tubes, a first lower display tube 101 and a second lower display tube 102, are fixedly connected to the base 100. They are arranged side-by-side for easy comparison and observation by the audience. In a preferred embodiment, both the first lower display tube 101 and the second lower display tube 102 are made of transparent material, allowing for easy demonstration of the rising process of water vapor. It is easily understood that the first lower display tube 101 and the second lower display tube 102 can also be made partially transparent.

[0020] Both the first lower display tube 101 and the second lower display tube 102 are cylindrical with openings at the top and bottom. The base 100 has through holes. The lower end of the first lower display tube 101 is connected to the base 100 through the through holes, and the lower end of the second lower display tube 102 is also connected to the base 100 through the through holes. Therefore, the water vapor generated by the water vapor generator 105 can enter the first lower display tube 101 from the lower end and enter the second lower display tube 102 from the lower end.

[0021] Both the first upper display tube 103 and the second upper display tube 104 are cylindrical with openings at the top and bottom. The first upper display tube 103 has the same diameter as the first lower display tube 101, and the second upper display tube 104 has the same diameter as the second lower display tube 102. When demonstrating the breathability function, the first upper display tube 103 is stacked on top of the first lower display tube 101, and a first fabric 106 is secured between the lower end of the first upper display tube 103 and the upper end of the first lower display tube 101. It should be noted that the first fabric 106 should cover the entire upper opening of the first lower display tube 101. The second upper display tube 104 is stacked on top of the second lower display tube 102, and a second fabric 107 is secured between the lower end of the second upper display tube 104 and the upper end of the second lower display tube 102. It should be noted that the second fabric 107 should cover the upper opening of the second lower display tube 102. In this way, the water vapor generated by the water vapor generator 105 rises in the first lower display cylinder 101 and the second lower display cylinder 102. The corresponding upper display cylinder containing the fabric with better breathability among the first fabric 106 and the second fabric 107 (the first fabric 106 corresponds to the first upper display cylinder 103, and the second fabric 107 corresponds to the second upper display cylinder 104) will generate water vapor more quickly, thereby demonstrating the breathability of the fabric.

[0022] Example 2, as shown in Figures 3 and 4, involves a fabric breathability display device, including a base 200, an airflow transition chamber 201, a first lower display cylinder 202, a second lower display cylinder 203, a first upper display cylinder 204, and a second upper display cylinder 205. A water vapor generator 206 is installed inside the base 200, generating water vapor for display purposes. The water vapor generator 206 and its associated water storage chamber are fixedly installed in the base 200. An LED strip 207 can be installed around the base 200 to enhance aesthetics.

[0023] An airflow transition chamber 201 is mounted on the base 200. Two display tubes, a first lower display tube 202 and a second lower display tube 203, are fixedly connected to the top of the airflow transition chamber 201, arranged side-by-side for easy comparison and observation by the audience. A water vapor channel 201a is provided inside the airflow transition chamber 201 for water vapor circulation. An impeller 208 is rotatably mounted inside the water vapor channel 201a, and the lower end of the water vapor channel 201a is connected to the base 200. When water vapor passes through the impeller 208, it drives the impeller 208 to rotate. The airflow transition chamber 201 is made of transparent material, allowing the impeller 208 to be directly observed, enabling the audience to intuitively perceive the water vapor flow through the rotation of the impeller 208.

[0024] Both the first lower display tube 202 and the second lower display tube 203 are cylindrical with openings at the top and bottom. The lower ends of the first lower display tube 202 and the second lower display tube 203 are connected to the top of the water vapor channel 201a. Therefore, the water vapor generated by the water vapor generator 206 can enter the first lower display tube 202 from the lower end and enter the second lower display tube 203 from the lower end.

[0025] Both the first upper display tube 204 and the second upper display tube 205 are cylindrical with openings at the top and bottom. Annular support plates 209 are provided at the upper ends of the first lower display tube 202, the second lower display tube 203, the lower ends of the first upper display tube 204, and the lower ends of the second upper display tube 205. When the first upper display tube 204 is stacked on top of the first lower display tube 202, the annular support plates 209 of both tubes hold the first fabric 210. When the second upper display tube 205 is stacked on top of the second lower display tube 203, the annular support plates 209 of both tubes hold the second fabric 211. Thus, during display, the fabric does not need to extend beyond the outer wall of the display tube, and the fabric can be made to approximate the shape of the annular support plates 209, only needing to cover the central hole of the annular support plates 209. This further improves operational convenience. Similar to Embodiment 1, the first lower display tube 202, the second lower display tube 203, the first upper display tube 204, and the second upper display tube 205 are all transparent (this transparency is not shown in Figure 3).

[0026] To ensure the stability of the first upper display tube 204 stacked on the first lower display tube 202, and to ensure the stability of the second upper display tube stack 205 stacked on the second lower display tube 203, quick-release buckles 212 are correspondingly provided on the outer walls of the first upper display tube 204 and the first lower display tube 202, and quick-release buckles 212 are also correspondingly provided on the outer walls of the second upper display tube 205 and the second lower display tube 203, and the connection is completed by the quick-release buckles 212.

[0027] The method for demonstrating the breathability of the fabric using the fabric breathability demonstration device in this embodiment is the same as that in Embodiment 1, and will not be repeated here. However, in order to make the moisture that has passed through the fabric easier to observe, lighting fixtures 213, such as light strips, can be installed on the top of the first upper display cylinder 204 and the second upper display cylinder 205 to illuminate the moisture.
