[0002] Air filters are an important component used in many air handling systems, such as air circulation systems, fresh air systems, air conditioning, and automotive air intake systems.

[0003] Under the same filtration capacity, the air resistance of an air filter directly affects the energy consumption and other performance characteristics of the filtration product using that filter. Generally, with the same filtration capacity, the lower the air resistance of the filter, the lower the relative energy consumption of the filtration product using that filter, and the more energy-efficient it is.

[0004] However, air filter elements produced by different manufacturers have different air resistance performance. In order to help customers have a more intuitive understanding of the air resistance performance of different air filter elements and to help them accurately select a suitable low-energy-consumption air filter element, this filter element performance demonstration device has been specially developed.

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] See Figure 1-7 This utility model discloses a filter performance demonstration device, which can be used to demonstrate and test the air resistance performance of different air filter elements 300.

[0030] This filter performance demonstration device includes a mounting body 100, a blower 200, an air filter 300, a differential pressure sensor 400, a display 600, and a control module 700. The mounting body 100 has a ventilation channel 105, with an air inlet 106 and an air outlet 107 both connected to the outside of the mounting body 100. The blower 200 is located at one end of the ventilation channel 105 to introduce outside air into the ventilation channel 105 through the air inlet 106. The air filter 300 is detachably mounted in the ventilation channel 105. The differential pressure sensor 400 has a first air pressure acquisition unit 401 and a second air pressure acquisition unit 402, which can collect air pressure at corresponding locations. The pressure value is processed by the differential pressure sensor 400 to obtain the pressure difference value. The differential pressure sensor 400 is installed on the mounting body 100. The air pressure acquisition unit 1 401 and the air pressure acquisition unit 2 402 are both installed in the ventilation channel 105, respectively on both sides of the air filter element 300. The display 600 is installed on the mounting body 100. The control module 700 is installed on the mounting body 100 and connected to the differential pressure sensor 400 and the display 600. The control module 700 can read the information of the differential pressure sensor 400 and display it on the display 600.

[0031] During the demonstration, the filter performance demonstration device of this utility model places the air filter element 300 to be tested in the ventilation channel 105, then starts the blower 200, which introduces air from the air inlet 106 into the air supply channel and continuously and stably pushes it towards the air outlet 107. During this process, the air pressure difference before and after passing through the air filter element 300 can be acquired by the differential pressure sensor 400 and displayed visually on the display 600 under the control of the control module 700. This achieves the purpose of testing the air resistance of the air filter element 300.

[0032] When testing various air filters 300, since the air filters 300 are detachably installed in the ventilation channel 105, it is only necessary to replace the different air filters 300 accordingly for testing and demonstration comparison to draw conclusions about the air resistance performance of these filters and to know the energy-saving performance of the air filters 300 (the smaller the pressure difference measured by the differential pressure sensor 400, the smaller the air resistance of the air filter 300, and the more energy-efficient it is to use).

[0033] Example 1

[0034] In this embodiment of the disclosure, such as Figure 5 and Figure 7 As shown, the filter performance demonstration device includes: a mounting body 100, which has a ventilation channel 105, with an air inlet 106 and an air outlet 107 connected to the outside of the mounting body 100; a blower 200, located at one end of the ventilation channel 105, for introducing outside air into the ventilation channel 105 from the air inlet 106; an air filter 300, detachably mounted in the ventilation channel 105; and a differential pressure sensor 400, which has a wind pressure acquisition unit 401 and a wind pressure sensor. The second data acquisition unit 402 and the differential pressure sensor 400 are mounted on the mounting body 100. The first air pressure acquisition unit 401 and the second air pressure acquisition unit 402 are both located in the ventilation channel 105, respectively on both sides of the air filter element 300. The display 600 is mounted on the mounting body 100. The control module 700 is mounted on the mounting body 100 and connected to the differential pressure sensor 400 and the display 600. The control module 700 can read the information from the differential pressure sensor 400 and display it on the display 600.

[0035] Meanwhile, the control module 700 also connects to and controls the blower 200 to adjust its speed. A wind speed sensor 500 is also installed on the air outlet side of the blower 200 in the ventilation duct 105, and the wind speed sensor 500 is connected to the control module 700. The wind speed can also be displayed on the display 600 based on the detection of the wind speed sensor 500. By adjusting the speed of the blower 200, the resistance of the air filter 300 under different wind speeds and air volumes can be observed. The speed of the blower 200 can be adjusted by the control module 700 or by a dedicated controller. With the wind speed sensor 500 installed, the same wind speed and wind speed variation test environment can be adjusted for different air filters 300, making the demonstration process more reliable and comprehensive, and ensuring the accuracy of the test results.

[0036] Specifically, the blower 200 is located at one end of the ventilation duct 105 near the air inlet 106, the air filter 300 is located at one end of the ventilation duct 105 near the air outlet 107, the first air pressure acquisition unit 401 is located between the air filter 300 and the air outlet 107, and the second air pressure acquisition unit 402 is located between the air filter 300 and the blower 200. Filter screens 108 are installed at both the air inlet 106 and the air outlet 107.

[0037] Example 2

[0038] In this embodiment of the disclosure, such as Figure 6 As shown, the difference from Embodiment 1 is that one end of the mounting body 100 along its length is provided with a caster 111 for support, and the other end is provided with a pull rod 112 or a handle 113, or both a pull rod 112 and a handle 113 are provided at the same location. Furthermore, a storage battery 800 is provided on the mounting body 100, which is used to power the control module 700.

[0039] When movement is required, the casters 111 can be used for support, and then the device can be dragged by hand using the lever 112 or handle 113, just like moving a suitcase. This saves time and effort and is very convenient for use in trade shows (for demonstrating to customers or for buyers looking for suitable air filter 300 products). Furthermore, the inclusion of the battery 800 greatly facilitates the application of this filter performance demonstration device.

[0040] Example 3

[0041] In this embodiment of the disclosure, such as Figures 1-4 ,and Figure 7 As shown, the filter performance demonstration device includes: a mounting body 100, which has a ventilation channel 105, with both the air inlet 106 and the air outlet 107 of the ventilation channel 105 connected to the outside of the mounting body 100; a blower 200, located at one end of the ventilation channel 105, for introducing outside air into the ventilation channel 105 from the air inlet 106; an air filter 300, detachably mounted in the ventilation channel 105; and a differential pressure sensor 400, which can be selected from the SP50 series products of Shanghai Mengxi Sensor Technology Co., Ltd., and has wind pressure acquisition capabilities. The unit 401 and the air pressure acquisition unit 402 are respectively located on both sides of the air filter element 300. The differential pressure sensor 400 is mounted on the mounting body 100. The air pressure acquisition unit 401 and the air pressure acquisition unit 402 are both located in the ventilation channel 105. The display 600 is mounted on the mounting body 100. The control module 700, which can be a PLC module, is mounted on the mounting body 100 and connected to the differential pressure sensor 400 and the display 600. The control module 700 can read the information from the differential pressure sensor 400 and display it on the display 600.

[0042] The mounting body 100 includes a housing 101 and a cover 103. One side of the housing 101 is not closed, and the cover 103 is located on the unclosed side of the housing 101. One side of the cover 103 is hinged to the housing 101. The cover 103 can swing to close the housing 101 and then be connected to the housing 101 by a latch. One end of the housing 101 is provided with a caster 111 for support, and the other end is provided with a pull rod 112. The housing 101 contains a mounting body 114 and a battery 800. The battery 800 is located at the bottom of the housing 101. The mounting body 114 is located inside the housing 101 and is fixedly connected to it. A ventilation channel 105 is located on the mounting body 114. An air inlet 106 and an air outlet 107 are respectively located at both ends of the mounting body 114. The housing 101 has a clearance opening 102 opposite to the air inlet 106 and the air outlet 107.

[0043] During the demonstration, the lid 103 was in the position as follows: Figure 1 With the air filter 300 to be tested in the open position as shown, place it in the ventilation channel 105, then start the blower 200. The blower 200 draws air from the air inlet 106 into the ventilation channel and continuously and stably pushes it towards the air outlet 107. During this process, the air pressure difference before and after passing through the air filter 300 can be acquired by the differential pressure sensor 400 and displayed visually on the display 600 under the control of the control module 700. This serves the purpose of testing the air resistance of the air filter 300.

[0044] When testing various air filters 300, since the air filters 300 are detachably installed in the ventilation channel 105, it is only necessary to replace the different air filters 300 accordingly for testing and demonstration comparison to draw conclusions about the air resistance performance of these filters and to know the energy-saving performance of the air filters 300 (the smaller the pressure difference measured by the differential pressure sensor 400, the smaller the air resistance of the air filter 300, and the more energy-efficient it is to use).

[0045] Normally, when the box body 101 and the lid 103 are closed, the effect is as follows: Figure 4 The combination of the box body 101 and the box cover 103 provides excellent protection for all the functional components inside. Furthermore, with the pull rod 112 installed, it can be supported on the ground by the casters 111 and then dragged by hand using the pull rod 112, which is very convenient and labor-saving.

[0046] Furthermore, to facilitate lifting, handles 113 are provided on one side of the box body 101 in the width direction and on the side in the direction of the pull rod 112.

[0047] The battery 800 is a rechargeable battery 800, and it can also be equipped with a matching external charging plug for charging or plugging into an external power source when the battery is low.

[0048] In order to facilitate observation of the demonstration process on the display 600, the display 600 is set on the side of the mounting body 114 near the opening of the housing 101.

[0049] To facilitate the removal and replacement of the air filter 300, a perforated mounting port 109 is provided on one side of the ventilation channel 105, and U-shaped grooves 110 extending from the mounting port 109 to the bottom of the ventilation channel 105 are provided on both sides of the ventilation channel 105. During installation, the air filter 300 is inserted into the mounting port 109 and the two sides of the air filter 300 are embedded in the U-shaped grooves 110. If replacement is required, the air filter 300 can be simply pulled out from the mounting port 109 and another air filter 300 can be inserted.

[0050] The ventilation duct 105 is equipped with a blower 200 located at one end near the air inlet 106, an air filter 300 located at one end near the air outlet 107, a pressure sensor 401 located between the air filter 300 and the air outlet 107, and a pressure sensor 402 located between the air filter 300 and the blower 200. Similarly, a wind speed sensor 500 is also installed in the ventilation duct 105. The wind speed sensor 500 can be a product from the SF46 series of Shanghai Mengxi Sensor Technology Co., Ltd. Located between the air filter 300 and the blower 200, the wind speed sensor 500 is connected to the control module 700. Under the processing of the control module 700, the current wind speed and airflow are displayed on the display 600.

[0051] Both the air inlet 106 and the air outlet 107 are equipped with filter screens 108 for filtering and protecting the ventilation channel 105.

[0052] In addition, such as Figure 2 As shown, a storage compartment 104 can also be provided in the lid 103, which can be used to collect and store the air filter 300.

[0053] In summary, this filter performance demonstration device can be widely used to demonstrate its use to customers at exhibitions, client meetings, and other similar occasions. By comparing different air filters, and assuming the same filtration capacity (which is typically assessed and evaluated by a professional third-party testing organization), a superior air conditioning filter exhibits lower air resistance, resulting in lower relative energy consumption and greater energy efficiency for filtration products using that air filter 300. This provides customers with a more intuitive understanding of the air resistance performance of different air filter 300s, helping them accurately select a suitable, low-energy-consumption air filter 300.
