Description

Technical Field

[0001] This utility model belongs to the field of textile technology, specifically relating to a device for demonstrating the waterproof and breathable properties of fabrics. Background Technology

[0002] Water resistance and breathability are two important indicators for evaluating fabric properties. Currently, related technologies only allow for the testing of fabric's water resistance and breathability using specialized instruments, followed by descriptions of these properties based on the test data. This method is cumbersome and not convenient for demonstrating the fabric to consumers.

[0003] To address the aforementioned issues, patent document CN201796518U discloses a waterproof and breathable demonstration cup for showcasing fabric properties. This waterproof and breathable demonstration cup comprises an upper cup and a lower cup, both made of transparent material. The upper cup has a water injection hole at its bottom, and the lower cup has a circular base with a diameter larger than the bottom of the lower cup, ensuring greater stability. An air inlet is located on the wall of the lower cup, and a movable gate-shaped support is mounted thereon, with a fastening screw at the top of the gate-shaped support. The transparent material of this waterproof and breathable demonstration cup allows for a clear and intuitive demonstration of the properties. Due to its upper and lower cup structure, the upper cup can be filled with water, and the lower cup can be inflated by an external air pump, simultaneously demonstrating both waterproof and breathable properties. This waterproof and breathable demonstration cup has a simple structure, is small in size, and lightweight, making it widely applicable for demonstrations in various situations. However, this waterproof and breathable demonstration cup is not suitable for waterproof demonstrations using thicker fabrics. If the fabric thickness is greater than or equal to 1mm, the fit between the fabric and the waterproof and breathable demonstration cup is poor, resulting in poor sealing and easy water seepage at the edges, leading to unsatisfactory demonstration results. In other words, this waterproof and breathable demonstration cup cannot meet the waterproof demonstration needs of fabrics of different thicknesses. Utility Model Content

[0004] In view of this, the present invention provides a fabric waterproof and breathable performance demonstration device to solve the technical problem that the upper waterproof and breathable demonstration cup cannot meet the waterproof demonstration needs of fabrics of different thicknesses.

[0005] To achieve the above solution, the technical solution of this utility model is as follows:

[0006] This utility model provides a device for demonstrating the waterproof and breathable performance of fabrics, comprising:

[0007] The demonstration chamber includes a lower chamber and an upper chamber detachably placed on the lower chamber. The bottom of the upper chamber and the top of the lower chamber are both open. A water inlet is provided at the top of the upper chamber, and an air inlet is provided on the side wall and bottom wall of the lower chamber.

[0008] Two fasteners, located on either side of the demonstration cavity, are used to secure the upper and lower cavities during the demonstration; and

[0009] Two sealing gaskets.

[0010] The principle of this utility model's fabric waterproof and breathable performance demonstration device is as follows: by adding two sealing gaskets, the gaps between the bottom opening of the upper cavity and the fabric, and between the top opening of the lower cavity and the fabric can be sealed during the demonstration. This improves the fit and sealing between the fabric and the demonstration device during the demonstration, avoiding problems such as poor fit and sealing between the fabric and the waterproof and breathable demonstration cup, easy water seepage at the edges, and poor demonstration effect in the prior art.

[0011] In one example of the waterproof and breathable performance demonstration device for the fabric of this utility model, the surface of the sealing gasket is coated with a hydrophobic coating.

[0012] Specifically, this invention prevents water stains from remaining on the surface of the sealing gasket by coating it with a hydrophobic coating, thus avoiding the negative effects of water stains on the sealing gasket, such as aging, oxidation, and reduced sealing performance.

[0013] In one example of the waterproof and breathable performance demonstration device for fabric of this utility model, the surface of the sealing gasket is provided with several receiving grooves so that the two sealing gaskets can be bonded together with the fabric by the adhesive contained in the receiving grooves.

[0014] Specifically, this invention provides several receiving grooves on the surface of the sealing gaskets, allowing adhesive to be added into the grooves. The adhesive in the grooves bonds the two sealing gaskets to the fabric, improving the sealing performance between the sealing gaskets and the fabric, and further enhancing the demonstration effect.

[0015] In one example of the waterproof and breathable performance demonstration device for the fabric of this utility model, the sealing gasket is made of an elastomer with a Shore A hardness of 33-37HA.

[0016] Specifically, this invention uses an elastomer with a Shore A hardness of 33-37HA as the material for the sealing gasket, which balances sealing and deformability, making the demonstration device compatible with a variety of fabric materials.

[0017] In one example of the waterproof and breathable performance demonstration device for the fabric of this utility model, the thickness of the sealing gasket is 1.5-3mm.

[0018] In one example of the fabric waterproof and breathable performance demonstration device of this utility model, the fabric waterproof and breathable performance demonstration device further includes a pressure sensor, which is signal-connected to the fastener.

[0019] Specifically, by adding a pressure sensor and connecting the pressure sensor to the fastener signal, this utility model can monitor the pressure during the fastening process through the pressure sensor, thereby regulating the applied pressure and avoiding damage to the fabric and water seepage at the edges caused by excessive pressure [1].

[0020] In one example of the waterproof and breathable performance demonstration device for the fabric of this utility model, the pressure sensor is used to transmit the monitored pressure data to the control terminal via radio.

[0021] In one example of the waterproof and breathable performance demonstration device for the fabric of this utility model, the air inlet is connected to an air pump, and the air pump is connected to a wireless charging power supply.

[0022] Specifically, by connecting the air pump to the wireless charging power supply, this invention avoids the problems of poor flexibility in store display and high cost caused by pipeline connections in the prior art.

[0023] In one example of the waterproof and breathable performance demonstration device for the fabric of this utility model, the air pump and the wireless charging power supply are connected via a magnetic interface.

[0024] In one example of the demonstration device for the waterproof and breathable performance of the fabric of this utility model, the air pump is equipped with an output gas flow regulating valve. Attached Figure Description

[0045] The existing waterproof and breathable demonstration cup is not suitable for waterproof demonstrations using thicker fabrics. If the fabric thickness is greater than or equal to 1mm, the fit between the fabric and the waterproof and breathable demonstration cup is poor, resulting in poor sealing and easy water seepage at the edges, leading to unsatisfactory demonstration results. In other words, this waterproof and breathable demonstration cup cannot meet the waterproof demonstration needs of fabrics of different thicknesses.

[0046] To address the above problems, one embodiment of this utility model proposes a device for demonstrating the waterproof and breathable performance of fabrics, comprising:

[0047] The demonstration chamber includes a lower chamber 11 and an upper chamber 12 detachably placed on the lower chamber 11.

A water inlet 121 is provided at the top of the upper chamber 12, and an air inlet 111 is provided on the side wall or bottom wall of the lower chamber 11.

[0048] Two fasteners 13 are located on both sides of the demonstration cavity, respectively, for securing the upper cavity 12 and the lower cavity 11 during the demonstration; and

[0049] Two sealing gaskets 14 are provided. The surface of the sealing gaskets 14 is coated with a hydrophobic coating 141.

The thickness of the sealing gaskets 14 is 1.5-3mm, and the material of the sealing gaskets 14 is an elastomer with a Shore A hardness of 33-37HA.

[0050] In another embodiment of this utility model, an air pump 3 is connected to the air inlet, the air pump 3 is provided with an output gas flow regulating valve 31, the air pump 3 is connected to a wireless charging power supply 4, and the air pump 3 and the wireless charging power supply 4 are connected through a magnetic interface.

[0051] In another embodiment of this utility model, the fabric waterproof and breathable performance demonstration device further includes a pressure sensor 5, which is signal-connected to the fastener 13. The pressure sensor 5 is used to transmit the monitored pressure data to the control terminal via radio.

[0052] The present invention will be described in detail below through specific examples and embodiments. It should also be understood that the following embodiments are only for specific illustration of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made by those skilled in the art based on the above description of the present invention are within the scope of protection of the present invention. The specific process parameters, etc., in the following examples are merely examples within a suitable range; that is, those skilled in the art can make appropriate selections within the appropriate range based on the description herein, and are not intended to be limited to the specific values ​​in the examples below.

[0053] Example 1

[0054] This embodiment provides a fabric waterproof and breathable performance demonstration device, which is used to demonstrate the waterproof and / or breathable performance of a fabric to consumers and other audiences. Figures 1 to 3 This is a schematic diagram of the structure of the fabric waterproof and breathable performance demonstration device provided in Embodiment 1 of this utility model. The fabric waterproof and breathable performance demonstration device provided in Embodiment 1 of this utility model includes a demonstration chamber, two fasteners 13 and two sealing gaskets 14.

[0055] like Figures 1 to 3 As shown, the demonstration chamber includes a lower chamber 11 and an upper chamber 12 detachably placed on the lower chamber 11. Both the bottom of the upper chamber 12 and the top of the lower chamber 11 are open; in other words, the bottom of the upper chamber 12 has no bottom cover, and the top of the lower chamber 11 has no top cover. The specifications of the opening at the bottom of the upper chamber 12 are the same as the specifications of the opening at the top of the lower chamber 11. A water inlet 121 is provided at the top of the upper chamber 12. An air inlet 111 is provided on the side wall of the lower chamber 11. The size of the water inlet 121 is not limited; it can be a hole or an opening covering the top surface of the upper chamber 12. If the water inlet 121 is an opening covering the top surface of the upper chamber 12, the fabric waterproof and breathable performance demonstration device also includes a top cover (not shown) placed on the upper chamber 12. The water inlet 121 is used to inject water into the demonstration chamber during the demonstration to facilitate the demonstration of the fabric's waterproof performance. The air inlet 111 is used to introduce pressurized gas into the demonstration chamber during the demonstration to improve the breathability of the fabric. Both the lower chamber 11 and the upper chamber 12 are made of transparent material, such as glass.

[0056] like Figures 1 to 3As shown, two fasteners 13 are located on both sides of the demonstration cavity, used to secure the upper cavity 12 and the lower cavity 11 during demonstration. Specifically, the two fasteners 13 are fixedly installed on both sides of the demonstration cavity. In other words, during demonstration, the upper cavity 12 and the lower cavity 11 are secured by the fasteners 13 on both sides. Each fastener 13 includes a first element and a second element that mates with the first element. One of the first and second elements is fixedly installed on the upper cavity 12, and the other is fixedly installed on the lower cavity 11. Examples of fasteners 13 include spring clips. Spring clips are prior art and will not be described further here.

[0057] like Figures 4 to 5 As shown, two sealing gaskets 14 are used to seal the gaps between the bottom opening of the upper cavity 12 and the fabric 2, and between the top opening of the lower cavity 11 and the fabric 2, respectively, during the demonstration. The surface of the sealing gaskets 14 is coated with a hydrophobic coating 141, and the surface of the sealing gaskets 14 has several receiving grooves 142 to facilitate bonding the two sealing gaskets 14 to the fabric 2 using adhesive contained within the receiving grooves 142. Specifically, all receiving grooves 142 are located at the edges of the sealing gaskets 14. The thickness of the sealing gaskets 14 is 1.5-3 mm, and the material of the sealing gaskets 14 is an elastomer with a Shore A hardness of 33-37 HA. Examples of elastomers include silicone rubber and silicone. There are no restrictions on the material of the hydrophobic coating 141; examples include organosilicon (such as polydimethylsiloxane, fluorosilane modified materials), fluorocarbon polymers (such as polytetrafluoroethylene, fluorinated nano-silica), and modified polymer materials (such as organosilicon side-chain modified polyester resin).

[0058] Specifically, this embodiment prevents water stains from remaining on the surface of the sealing gasket 14 by applying a hydrophobic coating 141, thus avoiding negative impacts such as aging, oxidation, and reduced sealing performance caused by water stains. This embodiment also provides several receiving grooves 142 on the surface of the sealing gasket 14, allowing adhesive to be added into these grooves. The adhesive then bonds the two sealing gaskets 14 to the fabric 2, improving the seal between the sealing gaskets 14 and the fabric 2, thereby further enhancing the demonstration effect. Finally, this embodiment uses an elastomer with a Shore A hardness of 33-37 HA as the material for the sealing gasket 14, balancing sealing and deformability, making the demonstration device compatible with various fabric materials.

[0059] The principle of the fabric waterproof and breathable performance demonstration device in this embodiment is as follows: by adding two sealing gaskets 14, the gaps between the bottom opening of the upper cavity 12 and the fabric 2 and the top opening of the lower cavity 11 and the fabric 2 can be sealed during the demonstration. This improves the fit and sealing between the fabric 2 and the demonstration device during the demonstration, avoiding problems such as poor fit, poor sealing, easy water seepage at the edges, and poor demonstration effect in the prior art.

[0060] Example 2

[0061] This embodiment provides a device for demonstrating the waterproof and breathable performance of fabrics.

[0062] like Figure 6 As shown, the difference between the fabric waterproof and breathable performance demonstration device of Embodiment 2 and Embodiment 1 is that: the air inlet 111 is located on the bottom wall of the lower cavity 11 and is connected to an air pump 3. The air pump 3 is equipped with an output gas flow regulating valve (not shown). The air pump 3 is connected to a wireless charging power supply 4, and the air pump 3 and the wireless charging power supply 4 are connected through a magnetic interface. There are no restrictions on the model of the air pump 3, such as a 370W vortex air pump fan. There are no restrictions on the model of the wireless charging power supply 4, such as a 403090P lithium polymer battery. The air pump 3 and the wireless charging power supply 4 are located in a housing 6. The material of the housing 6 can be metal, etc. The housing 6 is located on the bottom side of the lower cavity 11, and the bottom side of the housing 6 is fixedly installed on the base 7.

[0063] Specifically, this embodiment connects the air pump 3 to the wireless charging power supply 4, avoiding the problems of poor flexibility in store display demonstrations and high costs caused by pipeline connections in the prior art. Furthermore, by setting the connection between the air pump 3 and the wireless charging power supply 4 via a magnetic interface, this embodiment further avoids the problems of poor flexibility in store display demonstrations and high costs caused by pipeline connections in the prior art.

[0064] Example 3

[0065] This embodiment provides a device for demonstrating the waterproof and breathable performance of fabrics.

[0066] like Figure 7 As shown, the difference between the fabric waterproof and breathable performance demonstration device of Embodiment 3 and Embodiment 2 is that it also includes a pressure sensor 5. The pressure sensor 5 is signal-connected to the fastener 13. The pressure sensor 5 is used to transmit the monitored pressure data to a control terminal (e.g., a mobile phone) via radio (e.g., Bluetooth). The range of the pressure sensor 5 can be 0-5N, and the accuracy is at least ±0.05N. There are no restrictions on the model of the pressure sensor 5, such as an MS5803-14BA pressure sensor.

[0067] Specifically, this embodiment adds a pressure sensor 5 and connects the pressure sensor 5 to the fastener 13. The pressure sensor 5 can monitor the pressure during the fastening process and adjust the applied pressure to avoid damage to the fabric and water seepage at the edges caused by excessive pressure.

[0068] In this embodiment, the fabric waterproof and breathable performance demonstration device is operated by adding adhesive to the receiving grooves 142 of both sealing gaskets 14 and curing them at room temperature. Then, one sealing gasket 14, fabric 2, and another sealing gasket 14 are stacked in sequence, and the adhesive in the receiving grooves 142 is used to bond the sealing gasket 14, fabric 2, and another sealing gasket 14 together. The side of the sealing gasket 14 with the receiving groove 142 is adjacent to the fabric 2. The stacked body is placed on the opening at the top of the lower cavity 11, and the opening at the bottom of the upper cavity 12 is placed on the other side of the stacked body, that is, the side away from the opening at the top of the lower cavity 11. The upper cavity 12 is fastened to the lower cavity 11 by manually driving the fastener 13. During this process, the pressure data monitored by the pressure sensor 5 is viewed through the control terminal. If the pressure data is too high (for example, exceeding 3N), the force is reduced.

[0069] Water is injected into the upper cavity 12 through the water inlet 121, and the water in the upper cavity 12 is observed to see if it can seep down through the fabric 2, thus visually demonstrating the waterproofness of the fabric 2.

[0070] To demonstrate the breathability of the fabric, the air pump 3 needs to be started, and gas with a certain pressure (e.g., 150 Pa) (flow rate of 0.8-1.2 m³ / min) is injected into the lower cavity 11 through the air inlet 111. Observe whether the gas in the lower cavity 12 can pass through the fabric 2 and enter the upper cavity 12, thereby causing the water in the upper cavity 12 to generate bubbles. If bubbles can be generated, the fabric 2 is breathable; if bubbles cannot be generated, the fabric 2 is not breathable.

[0071] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
