[0063] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0064] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0065] In view of this, please refer to Figures 3 to 9 This utility model provides a heat exchange unit 100, which is suitable for air handling equipment such as air conditioners and dehumidifiers. It includes a heat exchange component 110, a first water collection tray 120, a first heat insulation part 130, and a clamping member 140. The heat exchange component 110 has a heat exchange pipe 111 for transmitting the heat exchange medium, enabling efficient heat exchange with the external environment. The heat exchange pipe 111 can be made of metal materials such as copper or aluminum to ensure good thermal conductivity. The first water collection tray 120 is connected to the heat exchange component 110 and has an opening 122 facing the first water collection cavity 121 of the heat exchange component 110. This cavity collects condensate generated during the heat exchange process, ensuring that the condensate does not drip onto other components, causing damage or reduced efficiency. For ease of understanding, the direction from the heat exchange component 110 to the first water collection tray 120 is defined as the first direction X. Thus, condensate can drip along the first direction X into the first water collection cavity 121.

[0066] It should be noted that the actual relative position of the heat exchange component 110 and the first water receiving tray 120 depends on the usage scenario of the heat exchange component 110. In some embodiments, after the heat exchange component 110 is installed, the first direction X can be vertical. In this case, the first water receiving tray 120 is located below the heat exchange component 110 to collect the condensate dripping from the heat exchange component 110 along the first direction X. In other embodiments, after the heat exchange component 110 is installed, the first direction X may be horizontal. In this case, the heat exchange component 110 may also include another water receiving container, which can be located on the side of the heat exchange component 110 perpendicular to the vertical direction, so that the other water receiving container is used to collect the condensate dripping from the heat exchange component 110. For ease of description, the following example illustrates the scenario where the heat exchange component 110 is installed, the first direction X is vertical, and the first water receiving tray 120 is located below the heat exchange component 110.

[0067] To improve the overall thermal insulation performance, a first heat insulation part 130 is connected to the side wall of the first water receiving tray 120 away from the first water receiving cavity 121. The first heat insulation part 130 effectively prevents heat exchange between the side wall of the first water receiving tray 120 away from the first water receiving cavity 121 and the surrounding air, thereby reducing condensate buildup on this side wall and preventing secondary contamination of the equipment, thus improving system stability and service life. The connection method between the first heat insulation part 130 and the first water receiving tray 120 includes, but is not limited to, adhesive bonding and snap-fit ​​connections, to ensure a secure connection and easy installation. The clamping member 140 includes a first clamping part 141 and a second clamping part 142, with one end connected and the other end spaced apart. This allows a portion of the first heat insulation part 130 and a portion of the first water receiving tray 120 to be securely clamped between the first clamping part 141 and the second clamping part 142, increasing the stability and reliability of the entire device.

[0068] In some embodiments, the clamping member 140 may be designed with an elastic connection between the first clamping portion 141 and the second clamping portion 142, so as to adapt to heat exchange components 110 and water receiving trays of different sizes during installation, ensuring a tight clamping and preventing loosening. In other embodiments, the first clamping portion 141 may rotate relative to the second clamping portion 142 and be able to engage with the first water receiving tray 120. Specifically, the first clamping portion 141 may rotate in a direction closer to or farther from the second clamping portion 142, thereby reducing or increasing the distance between the two, thus facilitating flexible installation.

[0069] Compared to related technologies that use adhesive to fix the insulation layer to the drip tray, the clamping member 140 in this application effectively avoids fixation failure caused by adhesive aging, significantly improving the durability and safety of the device. Furthermore, the number of clamping members 140 can be flexibly adjusted according to the shape of the first drip tray 120 and the size of the first insulation part 130, ensuring that each part is effectively fixed, ensuring connection reliability while improving flexibility. In addition, the clamping member 140 used to fix the first insulation part 130 in this application also effectively improves the convenience of later maintenance. When the first insulation part 130 needs to be replaced, it can be easily disassembled simply by loosening the clamping member 140. Compared to adhesive connections, the operation is simpler, greatly shortening maintenance time and reducing maintenance costs. At the same time, no adhesive residue is left on the surface of the first drip tray 120, maintaining the cleanliness and aesthetics of the equipment, while ensuring that the replaced first insulation part 130 can effectively contact the first drip tray 120, ensuring the insulation effect and improving the user experience.

[0070] Please see Figure 5 and Figure 8 The first water receiving tray 120 includes a first side plate 123, with an opening 122 formed on one side of the first side plate 123 along the first direction X, allowing condensate to flow smoothly into the first water receiving cavity 121 through the opening 122, and also facilitating the installation of the heat exchange assembly 110. The first heat insulation part 130 includes a first layer 131, which can be connected to the side wall of the first side plate 123 away from the opening 122 by means including but not limited to adhesive bonding, to provide additional heat insulation protection. Specifically, one of the first clamping part 141 and the second clamping part 142 abuts against the side of the first layer 131 away from the first side plate 123, while the other passes through the opening 122 and abuts against the side of the first side plate 123 away from the first layer 131. That is, the edge of the first side plate 123 facing the opening 122 and the edge of the first layer 131 near the opening 122 are clamped between the first clamping part 141 and the second clamping part 142, thereby ensuring a tight bond between the first layer 131 and the first side plate 123 and effectively improving the heat insulation effect.

[0071] Please see Figure 5To ensure effective contact between air and the heat exchange component 110, in some embodiments, the first water collection tray 120 not only collects condensate but also guides airflow. Specifically, the first water collection tray 120 has an air guide hole 124 extending through the first direction X. Airflow can then pass through this air guide hole 124 and contact the heat exchange component 110, thereby achieving sufficient heat exchange and improving heat exchange efficiency. To ensure effective collection of condensate, the first water collection cavity 121 is arranged around the air guide hole 124 to ensure that condensate falling from the heat exchange component 110 is effectively collected and does not flow into the air guide hole 124, affecting airflow. The first side plate 123 is located between the first water receiving cavity 121 and the air guide hole 124, so that the condensate will not be affected by the wind force during the air guiding process. At the same time, the design of the air guide hole 124 also avoids the airflow from directly impacting the water receiving cavity, ensuring the smooth collection of condensate and the uniform distribution of airflow. That is, the first side plate 123 not only plays a separating role, but also enhances the structural strength.

[0072] The first layer 131 is connected to the side wall of the first side plate 123 facing the air guide hole 124. Thus, the clamping member 140 can be clamped at the end edge of the first side plate 123 near the air guide hole 124. Compared with the clamping member 140 being located away from the air guide hole 124, this avoids positional interference between the clamping member 140 and the outer shell 210 of the heat exchange unit 100, avoids unnecessary contact and friction, reduces losses caused by friction, extends the service life of the device, and maintains the compactness and aesthetics of the overall structure.

[0073] Please see Figure 6 and Figure 8 Specifically, the water receiving tray also includes a base plate 125 opposite to the opening 122, with a protrusion 1251 on the side of the base plate 125 facing away from the opening 122. The first heat insulation part 130 includes a second layer 132, which is connected to the side wall of the base plate 125 facing away from the opening 122. The first clamping part 141 and the second clamping part 142 respectively abut against the protrusion 1251 on both sides perpendicular to the first direction X, and at least part of the second layer 132 is clamped between the clamping part 140 and the protrusion 1251. That is, the first heat insulation part 130 can also cover the side of the base plate 125 facing away from the water receiving cavity to further improve the heat insulation effect. The protrusion 1251 not only enhances the support of the base plate 125, but also provides a stable force point for the clamping member 140, ensuring that the second layer 132 can be firmly clamped by the first clamping part 141 and the second clamping part 142, preventing it from shifting during use, further enhancing the stability of the first heat insulation part 130, thereby effectively isolating heat transfer and improving the overall thermal protection performance of the device.

[0074] In some embodiments, the second layer 132 covers the protrusion 1251, and at least a portion of the second layer 132 is clamped between the first clamping portion 141 and the protrusion 1251, while at least a portion is also clamped between the second clamping portion 142 and the protrusion 1251. Thus, under the combined action of the protrusion 1251, the first clamping portion 141, and the second clamping portion 142, the second layer 132 is doubly clamped, effectively resisting external vibrations and impacts, ensuring the stability of the insulation layer during use, and further improving the durability and safety of the device.

[0075] In other embodiments, the second layer 132 is located on one side of the protrusion 1251. Specifically, the second layer 132 includes a side portion connected to one side of the protrusion 1251. One of the first clamping portion 141 and the second clamping portion 142 abuts against the side portion opposite to the protrusion 1251, and the other abuts against the side of the protrusion 1251 opposite to the side portion. That is, the second layer 132 only contacts one side of the protrusion 1251, which improves the ease of installation, reduces the complexity of the installation process, and ensures effective coverage and fixation of the insulation layer.

[0076] Please see Figure 8 In some embodiments, the first water receiving tray 120 includes a first side plate 123, one end of which is connected to a base plate 125 along a first direction X, and an opening 122 is formed on the side facing away from the base plate 125. The first heat insulation part 130 includes a first layer 131 and a second layer 132. The first layer 131 is connected to the side wall of the first side plate 123 facing away from the opening 122, and the second layer 132 is connected to the side wall of the base plate 125 facing away from the opening 122. Furthermore, the first layer 131 is fixed to the first side plate 123 by a clamping member 140, and the second layer 132 is fixed to the protrusion 1251 by the clamping member 140, so that the outer wall of the first water receiving tray 120 can be covered by the first heat insulation part 130, effectively isolating internal and external heat exchange and ensuring stable internal temperature of the device.

[0077] The first layer 131 and the second layer 132 can be designed as a single piece to reduce seams and improve thermal insulation. Alternatively, the first layer 131 and the second layer 132 can be separate pieces, with the edges of the first layer 131 and the second layer 132 overlapping or staggered at the junction to ensure thermal insulation.

[0078] Please see Figure 7To ensure the clamping member 140 effectively secures the first heat insulation portion 130 while minimizing its impact on the heat exchange unit 100 system, in some embodiments, the dimensions of the first clamping portion 141 and the second clamping portion 142 are not equal along the first direction X. For ease of description, an example is given where the first clamping portion 141 abuts against the first water receiving tray 120 and the second clamping portion 142 abuts against the first heat insulation portion 130. Specifically, the length of the first clamping portion 141 from the end connecting to the second clamping portion 142 to the end away from the second clamping portion 142 is L1, which is the length of the first clamping portion 141 along the first direction X. The length of the second clamping portion 142 from the end connecting to the first clamping portion 141 to the end away from the first clamping portion 141 is L2, which is the length of the second clamping portion 142 along the first direction X. Where L1≤L2, the length of the first clamping part 141, which is inserted into the opening 122 and abuts against the first water receiving tray 120, is shorter, reducing the impact of the first clamping part 141 on the capacity of the first water receiving cavity 121. Meanwhile, the length of the second clamping part 142, located on the side of the first heat insulation part 130 opposite to the first water receiving tray 120, is longer, increasing the contact area between the second clamping part 142 and the first heat insulation part 130, ensuring a stable clamping of the first heat insulation part 130.

[0079] It should be noted that if the first clamping part 141 is too long, it may guide the liquid in the first water receiving cavity 121. That is, under the action of surface tension, the liquid may easily flow out through the gap between the first clamping part 141 and the first water receiving tray 120, resulting in condensate leakage and affecting the normal operation of the equipment.

[0080] In some embodiments, in order to further enhance the stability and reliability of the clamping member 140, anti-slip textures or a material layer with a high coefficient of friction, including but not limited to rubber, can be provided on the inner side of the first clamping part 141 and the second clamping part 142 to effectively prevent the clamping member 140 from slipping relative to the first water receiving tray 120 or the first heat insulation part 130 due to the presence of condensate.

[0081] To improve the ease of installation of the clamping component 140, please refer to [link / reference]. Figure 7 In some embodiments, along the direction from the end of the first clamping portion 141 connecting to the second clamping portion 142 to the end away from the second clamping portion 142, the end of the first clamping portion 141 away from the second clamping portion 142 is bent in a direction gradually away from the first water receiving tray 120. Therefore, during the installation of the clamping member 140, the bent end of the first clamping portion 141 can smoothly avoid the edge of the first water receiving tray 120, reducing installation obstacles and ensuring that the clamping member 140 is quickly and accurately positioned, thereby improving the assembly efficiency and stability of the overall device.

[0082] In other embodiments, the end of the second clamping portion 142 away from the first clamping portion 141 is bent away from the first clamping portion 141. This bend effectively avoids the edge of the first heat insulation portion 130, further reducing frictional resistance during installation and ensuring a tight fit between the clamping member 140 and the heat insulation portion, thus improving the stability and sealing of the overall structure. Furthermore, the bend at the end of the second clamping portion 142 effectively prevents deformation or damage to the edge of the first heat insulation portion 130 during installation, or even detachment from the first water receiving tray 120. This reduces installation difficulty, and the bend design also facilitates quick disassembly and reinstallation during maintenance, reducing maintenance costs and time.

[0083] Furthermore, in order to improve the fit between the second clamping portion 142 and the first heat insulation portion 130, in some embodiments, please refer to... Figure 7 Along the direction from the end of the second clamping part 142 connecting to the end of the first clamping part 141 away from the first clamping part 141, the end of the second clamping part 142 away from the first clamping part 141 is bent towards the first heat insulation part 130. This increases the contact area and pressure distribution between the clamping part 140 and the sponge layer, allowing the bent end of the second clamping part 142 to fit tightly against the surface of the first heat insulation part 130, enhancing the clamping effect. In some embodiments, the first heat insulation part 130 includes a sponge layer, so the bent end of the second clamping part 142 can be embedded in the sponge layer, forming a more robust clamping structure, effectively preventing displacement of the heat insulation material, further improving the heat insulation effect and the overall operational stability of the device. Furthermore, the sponge layer provides a certain cushioning effect, and in some applications, it can absorb condensate, preventing direct dripping and further protecting internal components and extending service life. In other applications, a waterproof coating can be applied to the surface of the sponge layer to prevent condensate from seeping into the sponge layer, thereby maintaining its heat insulation performance.

[0084] In some embodiments, the first heat insulation part 130 can be bonded to the first drip tray 120. This bonding method not only simplifies the manufacturing process but also ensures a tight fit between the two, avoiding loosening caused by vibration or temperature changes. Simultaneously, the clamping member 140 connects the edge of the first heat insulation part 130 to the edge of the first drip tray 120, preventing the first heat insulation part 130 from separating from the first drip tray 120 after long-term use or under the influence of airflow, thus preventing a decrease in heat insulation effect. Specifically, high-temperature resistant, high-adhesion adhesive or double-sided tape can be used for bonding to ensure that detachment does not occur during long-term operation.

[0085] The first heat insulation part 130 can also be designed as a multi-layer structure. In some embodiments, the first heat insulation part 130 includes a metal layer and a sponge layer stacked on top of each other, wherein the metal layer is connected to the first water receiving tray 120, and the sponge layer covers the metal layer to form a composite heat insulation structure. The metal layer not only provides effective support strength but also effectively reflects heat, while the sponge layer provides good heat insulation. The two work together to significantly improve the heat insulation performance. To improve the heat insulation effect, a high-efficiency heat insulation material, including but not limited to aerogel board or ceramic fiber felt, can be placed between the metal layer and the sponge layer to form a multi-layer composite heat insulation structure, significantly reducing heat loss.

[0086] In some embodiments, the first clamping part 141 and the second clamping part 142 can be manufactured using integral forming methods, including but not limited to stamping, bending, or laser cutting, to ensure structural strength, reduce assembly steps, and minimize seams between components. This reduces the risk of corrosion or damage caused by condensation or other impurities entering the gaps, thereby improving overall stability. It is understood that the clamping member 140 can be made of a metal material with excellent elasticity, including but not limited to stainless steel and spring steel, to ensure good clamping force and elastic recovery during long-term use, further extending the service life of the device.

[0087] To improve the installation stability of the clamping member 140, in some embodiments, the first clamping part 141 is provided with a barb structure 143 on the side facing the second clamping part 142. The barb structure 143 can be located at the edge or middle of the end of the first clamping part 141 away from the second clamping part 142. Specifically, the barb structure 143 is integrally formed with the first clamping part 141, and it can be formed by bending or stamping processes. The barb structure 143 can apply additional pressure to the first water receiving tray 120 to ensure that the two fit tightly and prevent loosening due to vibration or temperature changes.

[0088] In other embodiments, the second clamping part 142 has a barb structure 143 on the side facing the first clamping part 141. Its position and shape can be similar to the barb structure 143 of the first clamping part 141, and it is also formed by an integral molding process. When the barb structure 143 of the first clamping part 141 is located at its edge away from the end of the second clamping part 142, the barb structure 143 of the second clamping part 142 is located at the middle position of its end away from the first clamping part 141. This avoids interference between the barb structure 143 of the first clamping part 141 and the barb structure 143 of the second clamping part 142, ensuring that they function independently and enhancing clamping stability. The tip of the barb structure 143 of the second clamping part 142 faces the first clamping part 141, effectively embedding into the surface of the first heat insulation part 130 to form a firm mechanical lock. This further prevents displacement or loosening of the clamping part due to external factors during long-term use, thereby ensuring the stability and reliability of the entire device.

[0089] To improve maintenance convenience, a quick release mechanism, including but not limited to a button or pull ring, can be provided at the end of the first clamping part 141 away from the second clamping part 142 and the end of the second clamping part 142 away from the first clamping part 141. This allows users to easily detach the barbed structure 143 from the first water receiving tray 120 or the first heat insulation part 130, facilitating disassembly and reinstallation and improving maintenance efficiency.

[0090] To improve the applicability of heat exchange unit 100, please refer to Figure 3 and Figure 4 In some embodiments, the heat exchange unit 100 further includes a second water receiving tray 150 and a second heat insulation portion 160. The second water receiving tray 150 is located on one side of the heat exchange assembly 110 along the second direction Y. The second water receiving tray 150 has a second water receiving cavity 151, which is used to collect condensate falling from the heat exchange assembly 110 along the second direction Y. The second heat insulation portion 160 is attached to the side wall of the second water receiving tray 150 away from the second water receiving cavity 151 to ensure the heat insulation effect of the second water receiving tray 150, prevent heat from being transferred to the external environment, and improve heat exchange efficiency.

[0091] Specifically, the first water collection tray 120 is located on one side of the heat exchange component 110 along the first direction X, while the second water collection tray 150 is located on the other side of the heat exchange component 110 along the second direction Y. Thus, the heat exchange component 110 has two installation states. Specifically, when the first direction X is parallel to the vertical direction, the condensate generated by the heat exchange component 110 can be collected by the first water collection tray 120. When the second direction Y is parallel to the vertical direction, the condensate generated by the heat exchange component 110 is collected by the second water collection tray 150. This ensures effective collection of condensate generated by the heat exchange component 110 and improves the installation flexibility of the heat exchange unit 100. Users can choose the appropriate installation method according to their actual needs, meeting the usage requirements in different scenarios, further enhancing the practicality and adaptability of the heat exchange unit 100.

[0092] It is understood that the heat exchange unit 100 includes multiple clamping members 140. Some clamping members 140 can be used to fix the first heat insulation part 130 to the first water receiving tray 120, while some clamping members 140 can be used to fix the second heat insulation part 160 to the second water receiving tray 150. To ensure the reliable connection between the second heat insulation part 160 and the second water receiving tray 150, the second water receiving tray 150 may have a protrusion 1251 similar to that of the first water receiving tray 120. At least a portion of the second heat insulation part 160 covers at least one side of the protrusion 1251. The clamping members can firmly clamp the covered portion of the second heat insulation part 160 onto the protrusion 1251, preventing it from sliding or falling off, and ensuring that the heat insulation effect is not affected.

[0093] Please see Figure 1 and Figure 2 A second aspect of this invention also provides a heat exchange module 200, which includes a heat exchange unit 100 as described in any of the above embodiments and a housing 210, wherein the heat exchange unit 100 is disposed inside the housing 210. The housing 210 is designed to protect the heat exchange unit 100 from external environmental factors, such as dust, moisture, and other contaminants. The housing 210 may be made of materials including but not limited to metals to ensure good mechanical strength and corrosion resistance, thereby ensuring stability during long-term use.

[0094] The outer casing 210 may include four side shells. An air inlet is provided on one side of the outer casing 210 along the first direction X, and an air outlet is provided on the opposite side. A first water receiving tray 120 is located on one side of the air inlet of the outer casing 210. The first water receiving tray 120 has multiple air guide holes 124. After air enters the outer casing 210 through the air inlet, it can pass through the first water receiving tray 120 through these air guide holes 124 and contact the heat exchange assembly 110, thereby performing heat exchange. The internal cavity shape of the outer casing 210 matches the heat exchange unit 100, ensuring a tight fit between the two while leaving sufficient gaps for airflow to achieve efficient heat exchange. The outer casing 210 is also equipped with necessary interfaces and channels for connecting external pipes, power cords, and other auxiliary equipment. For example, water inlet pipes and water outlet pipes can be easily connected to the heat exchange assembly 110. Furthermore, for ease of maintenance and repair, the outer casing 210 is typically designed for easy disassembly, such as using quick-release clips or screws for fixation.

[0095] Please see Figure 1 and Figure 2 A third aspect of this invention also provides an air handling unit 300, which includes a heat exchange module 200 and a drive module 310 as described in any of the above embodiments. The drive module 310 is responsible for generating airflow for heat exchange with the heat exchange assembly 110, thereby heating or cooling the air. In some embodiments, the drive module 310 includes one or more fans driven by electric motors, capable of operating at different speeds to adapt to different operating requirements. The position and number of fans are determined according to the specific design of the heat exchange module 200 to ensure optimal airflow distribution and heat exchange efficiency. Specifically, to optimize the airflow path, air guides or shrouds can be reasonably arranged around the heat exchange assembly 110 to guide the airflow evenly through the heat exchange pipe 111, thereby improving heat exchange efficiency.

[0096] The air handling unit 300 may also include an air guide module 320, which can adjust the direction and speed of the airflow generated by the drive module 310 to ensure uniform airflow distribution and improve heat exchange efficiency.

[0097] In some embodiments, the air guide module 320 and the drive module 310 are integrated within the housing 210 and are closely connected to the heat exchange module 200 to form a compact integrated structure. Specifically, the heat exchange module 200 is disposed within the housing 210 on one side near the air inlet, while the drive module 310 is located on the other side of the housing 210. The two are connected through the air guide module 320 to form a highly efficient heat exchange system.

[0098] In other embodiments, the heat exchange module 200 and the drive module 310 are independently configured and connected via the air guide module 320. Thus, driven by the drive module 310, the airflow, after being heated or cooled by the heat exchange module 200, is precisely guided to the target area via the air guide module 320, ensuring uniform heat distribution and improving overall thermal efficiency. Furthermore, the independent configuration facilitates modular maintenance, reduces repair costs, and enhances system flexibility.

[0099] It should be noted that the drive module 310 may include a motor and a fan assembly, with the motor driving the fan assembly to generate directional airflow. The drive module 310 may also include a control module for adjusting the motor speed and fan angle, precisely controlling airflow parameters, and optimizing heat exchange. The air guide module 320 may include an air guide duct and air guide blades. The air guide blade angle is adjustable to adapt to different environmental requirements, ensuring uniform airflow coverage of the target area and further improving heat exchange efficiency. The air guide duct may adopt a streamlined design to reduce airflow resistance and optimize the airflow path. The air guide blades can be adjusted manually or electrically; electric adjustment can be remotely controlled via the control system. A turbulence device may be added inside the air guide duct to further optimize airflow distribution, reduce eddy currents, and improve heat exchange efficiency.

[0100] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0101] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
