Description

Technical Field

[0001] This application belongs to the technical field of electrical appliances, and particularly relates to a heat exchange component and an air conditioner. Background Art

[0002] With the improvement of modern living standards, air conditioners have become one of the indispensable electrical appliances in people's daily lives. An air conditioner adjusts the indoor temperature by circulating a refrigerant (such as a refrigerant) in the refrigeration cycle system between the indoor and outdoor units. However, during the long-term operation of the air conditioner, due to various reasons (such as equipment aging, improper installation, improper use, etc.), the refrigerant in the refrigeration cycle system may leak. Refrigerant leakage not only causes a decline in the cooling effect of the air conditioner, increases energy consumption, but also pollutes the environment and may even pose a potential hazard to human health. However, in the prior art, it is impossible to determine whether the refrigerant leaks. Summary of the Utility Model

[0006] Since the heat exchange box body includes a middle partition and the heat exchanger is disposed in the heat exchange box body, the heat exchange box body accommodates the heat exchanger so that the air flow can exchange heat with the heat exchanger in the heat exchange box body to ensure the normal progress of heat exchange. At the same time, the heat exchange box body can protect the heat exchanger from being collided by external sundries and ensure the safety of the heat exchanger. Since the first refrigerant detector is disposed in the heat exchange box body and mounted on the middle partition, the middle partition supports the first refrigerant detector to ensure the stability of the installation of the first refrigerant detector. When refrigerant leaks in the heat exchange box body, the leaked refrigerant can be detected by the refrigerant detector, and it can be detected that the refrigerant leaks. Moreover, since the first refrigerant detector is mounted on the middle partition, the position of the first refrigerant detector is relatively fixed. Whether the heat exchange box body is horizontally installed (the air inlet direction of the heat exchange component is horizontal) or vertically installed (the air inlet direction of the heat exchange component is vertical), the leaked refrigerant will diffuse around from the leakage point, so that the leaked refrigerant will pass through the middle partition and thus be detected by the first refrigerant detector, enabling the first refrigerant detector to detect that the refrigerant leaks.

[0007] In some embodiments, the heat exchanger has a first side and a second side disposed opposite to each other, and the first refrigerant detector is located between the first side and the second side to further ensure that the first refrigerant detector can detect refrigerant leakage.

[0008] In some embodiments, the heat exchange assembly further includes: a pipe assembly communicating with the heat exchanger; a second refrigerant detector disposed in the heat exchange box body and on the same side of the heat exchanger as the pipe assembly and / or the bent portion of the coil of the heat exchanger to ensure detection efficiency and detection accuracy.

[0009] In some embodiments, the heat exchanger has a first side and a second side disposed opposite to each other, the pipe assembly and the second refrigerant detector are located on the first side; the distance between the first refrigerant detector and the first side is greater than or equal to the distance between the first refrigerant detector and the second side to further ensure detection efficiency and detection accuracy.

[0010] In some embodiments, the heat exchange assembly further includes a support plate connected to the heat exchanger and the heat exchange box body, the support plate and the pipe assembly and / or the bent portion of the coil of the heat exchanger are on the same side of the heat exchanger, the heat exchange box body includes a first side plate, and the pipe assembly passes through the first side plate; wherein, the second refrigerant detector is disposed between the support plate and the first side plate to improve detection efficiency and detection accuracy.

[0011] In some embodiments, the second refrigerant detector is disposed on the support plate or the first side plate to facilitate the installation of the second refrigerant detector.

[0012] In some embodiments, the heat exchange assembly further includes: a controller electrically connected to the first refrigerant detector and the second refrigerant detector; an alarm electrically connected to the controller; wherein, when the refrigerant concentration detected by the first refrigerant detector and / or the second refrigerant detector is greater than a first set concentration value within a set time or instantaneously greater than a second set concentration value, the alarm gives an alarm.

[0013] In some embodiments, the first refrigerant detector and the electronic control component are on the same side of the heat exchanger to facilitate wiring.

[0014] In some embodiments, along the air outlet direction, the projection of the first refrigerant detector and the driver on the middle partition at least partially overlaps to facilitate the installation of the first refrigerant detector.

[0015] In some embodiments, the heat exchange box body further includes a chassis, and the first refrigerant sensor is located between the heat exchanger and the chassis to improve detection efficiency and detection accuracy.

[0036] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0037] The following describes the present application in conjunction with the accompanying drawings and with reference to specific embodiments:

[0038] A heat exchange component and an air conditioner provided in this embodiment are intended to at least solve the technical problem of being unable to determine whether the refrigerant leaks to a certain extent.

[0039] Figure 1 is a schematic structural diagram of an air conditioner for some embodiments; Figure 2 is Figure 1 a top view of the air conditioner in Figure 3 is Figure 1 an installation schematic diagram of the first refrigerant detector of the air conditioner in Figure 1 、 Figure 2 andFigure 3 , the heat exchange component of the embodiment of the present application includes: a heat exchange box body 10, a heat exchanger 20, and a first refrigerant detector 30. The heat exchange box body 10 includes a middle partition plate 101. The heat exchanger 20 is arranged inside the heat exchange box body 10. The first refrigerant detector 30 is arranged inside the heat exchange box body 10 and is installed on the middle partition plate 101.

[0040] The heat exchanger 20 can be an evaporator.

[0041] Since the heat exchange box body 10 includes the middle partition plate 101 and the heat exchanger 20 is arranged inside the heat exchange box body 10, the heat exchange box body 10 accommodates the heat exchanger 20, so that air flow can exchange heat with the heat exchanger 20 inside the heat exchange box body 10 to ensure the normal progress of heat exchange. At the same time, the heat exchange box body 10 can protect the heat exchanger 20 and prevent the heat exchanger 20 from being collided by external sundries, ensuring the safety of the heat exchanger 20. Since the first refrigerant detector 30 is arranged inside the heat exchange box body 10 and is installed on the middle partition plate 101, the middle partition plate 101 supports the first refrigerant detector 30 to ensure the stability of the installation of the first refrigerant detector 30. When refrigerant leaks inside the heat exchange box body 10, the leaked refrigerant can be detected by the refrigerant detector, and the refrigerant leakage can be detected. Moreover, since the first refrigerant detector 30 is installed on the middle partition plate 101, the position of the first refrigerant detector 30 is relatively fixed. Whether the heat exchange box body 10 is horizontally installed (the air inlet direction of the heat exchange component is horizontal) or vertically installed (the air inlet direction of the heat exchange component is vertical), the leaked refrigerant will diffuse around from the leakage point, so that the leaked refrigerant will pass through the middle partition plate 101 and thus be detected by the first refrigerant detector 30, enabling the first refrigerant detector 30 to detect the refrigerant leakage.

[0042] In some embodiments, in order to further ensure that the first refrigerant detector 30 can detect refrigerant leakage, the heat exchanger 20 has a relatively arranged first side and a second side, and the first refrigerant detector 30 is located between the first side and the second side.

[0043] In some embodiments, the refrigerant leakage points are generally located on both sides of the heat exchanger 20. The first refrigerant detector 30 is located between the first side and the second side. That is to say, whether the heat exchanger 20 is horizontally installed (the air inlet direction of the heat exchange component is horizontal) or vertically installed (the air inlet direction of the heat exchange component is vertical), when refrigerant leaks from any one of the two sides of the heat exchanger 20, the refrigerant diffuses from the leakage point to any one of the two sides of the heat exchanger 20, so that the leaked refrigerant will pass through the middle partition plate 101 and thus be detected by the first refrigerant detector 30, enabling the first refrigerant detector 30 to detect the refrigerant leakage.

[0044] Combined with Figure 1 and Figure 2, in some embodiments, to ensure the detection efficiency and detection accuracy, the heat exchange assembly further includes: a pipe assembly 40 and a second refrigerant detector 50. The pipe assembly 40 is communicated with the heat exchanger 20. The second refrigerant detector 50 is arranged in the heat exchange box body 10 and is on the same side of the heat exchanger 20 as the coiled pipe bending part of the pipe assembly 40 and / or the heat exchanger 20.

[0045] In some embodiments, since the coiled pipe bending parts of the pipe assembly 40 and the heat exchanger 20 are key nodes of the refrigerant circulation and also potential refrigerant leakage risk points, due to the complex structure, stress concentration of the coiled pipe bending parts of the pipe assembly 40 and the heat exchanger 20, and the physical property changes of the refrigerant under high pressure or low temperature conditions, the leakage risk is relatively high. Therefore, the second refrigerant detector 50 is on the same side of the heat exchanger 20 as the coiled pipe bending part of the pipe assembly 40 and / or the heat exchanger 20. When refrigerant leakage occurs at the coiled pipe bending part of the pipe assembly 40 and / or the heat exchanger 20, the leaked refrigerant can be immediately detected by the second refrigerant detector 50, and the refrigerant leakage can be detected in time, improving the detection efficiency and also the detection accuracy.

[0046] In some embodiments, the pipe assembly 40 includes a refrigerant inlet pipe and a refrigerant outlet pipe. The refrigerant inlet pipe is communicated with the coiled pipe of the heat exchanger 20 to realize the input of the refrigerant, and the refrigerant outlet pipe is communicated with the coiled pipe of the heat exchanger 20 to realize the output of the refrigerant.

[0047] In some embodiments, to further ensure the detection efficiency and detection accuracy, the heat exchanger 20 has a first side and a second side arranged oppositely, and the pipe assembly 40 and the second refrigerant detector 50 are located on the first side. The distance between the first refrigerant detector 30 and the first side is greater than or equal to the distance between the first refrigerant detector 30 and the second side.

[0048] In some embodiments, since the pipe assembly 40 and the second refrigerant detector 50 are located on the first side, when refrigerant leakage occurs at the coiled pipe bending part of the heat exchanger 20 on the first side of the heat exchanger 20, the leaked refrigerant can be immediately detected by the second refrigerant detector 50, and the refrigerant leakage can be detected in time, improving the detection efficiency and also the detection accuracy. That is to say, the refrigerant leakage at the coiled pipe bending part of the heat exchanger 20 on the first side of the heat exchanger 20 can be detected by the second refrigerant detector 30. Since the distance between the first refrigerant detector 30 and the first side is greater than or equal to the distance between the first refrigerant detector 30 and the second side, that is to say, the first refrigerant detector 30 is closer to the second side. Therefore, when refrigerant leakage occurs at the coiled pipe bending part of the heat exchanger 20 on the second side of the heat exchanger 20, the leaked refrigerant can quickly diffuse to the first refrigerant detector 30 to be detected by the first refrigerant detector 30, and the refrigerant leakage can be detected in time, improving the detection efficiency and also the detection accuracy.

[0049] In some embodiments, the water pump of the air conditioner is located on the first side, and the distance between the first refrigerant detector 30 and the first side is greater than or equal to the distance between the first refrigerant detector 30 and the second side, which can also prevent the first refrigerant sensor 30 from occupying the installation space of the water pump, facilitating the installation of the water pump.

[0050] Figure 4 For Figure 1 Schematic diagram of the installation of the second refrigerant detector of the air conditioner on the first side plate; Figure 5 For Figure 1 Schematic diagram of the cooperation between the heat exchanger and the support plate of the air conditioner; Figure 6 For Figure 6 Schematic diagram of the installation of the second refrigerant detector of the air conditioner on the support plate. Combining Figure 4 , Figure 5 and Figure 6 In some embodiments, in order to enable the second refrigerant detector 50 to detect refrigerant leakage in a timely manner, the heat exchange assembly further includes a support plate 60 connected to the heat exchanger 20 and the heat exchange box body 10. The support plate 60 and the bent portion of the coil of the pipe assembly 40 and / or the heat exchanger 20 are on the same side of the heat exchanger 20. The heat exchange box body 10 includes a first side plate 102, and the pipe assembly 40 passes through the first side plate 102. Among them, the second refrigerant detector 50 is arranged between the support plate 60 and the first side plate 102.

[0051] Combining Figure 5 and Figure 6 In some embodiments, when the heat exchanger 20 is arranged in the heat exchange box body 10, the heat exchanger 20 can be supported by the support plate 60 to ensure the stability of the installation of the heat exchanger 20.

[0052] In some embodiments, the second refrigerant detector 50 is arranged between the support plate 60 and the first side plate 102. That is to say, the second refrigerant detector 50 and the bent portion of the coil of the pipe assembly 40 and / or the heat exchanger 20 are in the same area of the heat exchange box body 10. The second refrigerant detector 50 is close to the bent portion of the coil of the pipe assembly 40 and / or the heat exchanger 20. When refrigerant leakage occurs at the bent portion of the coil of the pipe assembly 40 and / or the heat exchanger 20, the leaked refrigerant can be immediately detected by the second refrigerant detector 50, enabling timely detection of refrigerant leakage, improving the detection efficiency and also improving the detection accuracy.

[0053] In some embodiments, holes are formed in the first side plate 102, and the pipeline assembly 40 passes through the holes and is connected to the outdoor unit of the air conditioner. When refrigerant leaks at the connection between the pipeline assembly 40 and the outdoor unit of the air conditioner, the refrigerant can enter the heat exchange box body 10 through the holes. That is to say, the refrigerant can reach between the support plate 60 and the first side plate 102. At this time, the second refrigerant detector 50 can detect the refrigerant entering the heat exchange box body 10 in time, improving the detection efficiency and the detection accuracy.

[0054] Combined with Figure 5 and Figure 6 , in some embodiments, for the convenience of installing the second refrigerant detector 50, the second refrigerant detector 50 is arranged on the support plate 60.

[0055] In some embodiments, there is a gap between the support plate 60 and the first side plate 102. When installing the second refrigerant detector 50 on the support plate 60, this gap serves as the installation space for the second refrigerant detector 50, facilitating the operation of the staff and the installation of the second refrigerant detector 50. Moreover, the support plate 60 is connected to the heat exchange box body 10, the heat exchanger 20, and the second refrigerant detector 50. That is to say, the support plate 40 has no connection relationship with other components in the heat exchange assembly. There is sufficient space on the support plate 60 to install the second refrigerant detector 50, further facilitating the installation of the second refrigerant detector 50 and avoiding the second refrigerant detector 50 interfering with the installation and operation of other components in the heat exchange box body 10, improving the overall performance and reliability of the heat exchange assembly, and ensuring the stable operation of the heat exchange assembly.

[0056] Combined with Figure 4 , in some embodiments, for the convenience of installing the second refrigerant detector 50, the second refrigerant detector 50 is arranged on the first side plate 102.

[0057] In some embodiments, there is a gap between the first side plate 102 and the heat exchanger 20. When installing the second refrigerant detector 50 on the first side plate 102, this gap can serve as the installation space for the second refrigerant detector 50, facilitating the operation of the staff and the installation of the second refrigerant detector 50. Moreover, the pipeline assembly 40 passes through the first side plate 102, and the second refrigerant detector 50 is connected to the first side plate 30. That is to say, the support plate 40 has no connection relationship with other components in the heat exchange box body 10. There is sufficient space on the first side plate 102 to install the second refrigerant detector 50, further facilitating the installation of the second refrigerant detector 50 and avoiding the second refrigerant detector 50 interfering with the installation and operation of other components in the heat exchange box body 10, improving the overall performance and reliability of the heat exchange assembly, and ensuring the stable operation of the heat exchange assembly.

[0058] Combined with Figure 4, in some embodiments, for the convenience of installing the second refrigerant detector 50, the first side plate 102 includes a main body 1021 and a folded edge 1022 that is angularly connected to the main body 1021. The second refrigerant detector 50 is disposed on the folded edge 1022.

[0059] In some embodiments, since the pipe assembly 40 needs to pass through the main body 1021 and be connected to the outdoor unit of the air conditioner, in order to prevent the second refrigerant detector 50 from occupying the installation space of the pipe assembly 40, the second refrigerant detector 50 is disposed on the folded edge 1022 to avoid spatial conflict between the installation of the second refrigerant detector 50 and the pipe assembly 40, facilitating the installation of the pipe assembly 40 and the second refrigerant detector 50. At the same time, the space occupied by the second refrigerant detector 50 can be minimized, improving the overall space utilization rate.

[0060] In some embodiments, the heat exchange box body 10 has an air outlet, and the folded edge 1022 and the air outlet are located on the same side of the heat exchange box body 10. The second refrigerant detector 50 can be installed and maintained through the air outlet without removing the chassis or the top cover 103 of the heat exchange box body 10, and the operation is simple.

[0061] In some embodiments, the included angle between the main body 1021 and the folded edge 1022 can be an acute angle, a right angle or an obtuse angle. Among them, when the main body 1021 is perpendicular to the folded edge 1022, the perpendicular relationship between the main body 1021 and the folded edge 1022 is not an absolute perpendicular in the geometric sense, and the angular relationship between the main body 1021 and the folded edge 1022 can be in the range of 90±3°.

[0062] In some embodiments, to further ensure the detection accuracy of the second refrigerant detector 50, the second refrigerant detector 50 is located between the heat exchanger 30 and the chassis of the heat exchange box body 10. When refrigerant leakage occurs, under the action of gravity, the refrigerant falls towards the chassis. During the falling process, the second refrigerant detector 50 detects the leaked refrigerant, and the refrigerant leakage can be detected in time, improving the detection efficiency and the detection accuracy.

[0063] In some embodiments, to prompt the user of the refrigerant leakage condition of the heat exchange component, the heat exchange component further includes: a controller (not shown in the figure) and an alarm (not shown in the figure). The controller is electrically connected to the first refrigerant detector 30 and the second refrigerant detector 50. The alarm is electrically connected to the controller. Among them, when the refrigerant concentration detected by the first refrigerant detector 30 and / or the second refrigerant detector 50 is greater than the first set concentration value within a set time or instantaneously greater than the second set concentration value, the alarm gives an alarm.

[0064] In some embodiments, the first refrigerant detector 30 detects the first refrigerant concentration value in the heat exchange box body 10 and sends the first refrigerant concentration value to the controller. The second refrigerant detector 50 detects the second refrigerant concentration value in the heat exchange box body 10 and sends the second refrigerant concentration value to the controller. The controller compares the first refrigerant concentration value and the second refrigerant concentration value with the first set concentration value. If any one of the first refrigerant concentration value and the second refrigerant concentration value continuously exceeds the first set concentration value within the set time, it indicates that there is a refrigerant leak in the heat exchange box body 10. At this time, the controller controls the alarm to alarm to remind the user that there is a refrigerant leak.

[0065] In some embodiments, the first refrigerant detector 30 detects the first refrigerant concentration value in the heat exchange box body 10 and sends the first refrigerant concentration value to the controller. The second refrigerant detector 50 detects the second refrigerant concentration value in the heat exchange box body 10 and sends the second refrigerant concentration value to the controller. The controller compares the first refrigerant concentration value and the second refrigerant concentration value with the second set concentration value. If any one of the first refrigerant concentration value and the second refrigerant concentration value instantaneously exceeds the first set concentration value, it indicates that there is a refrigerant leak in the heat exchange box body 10. At this time, the controller controls the alarm to alarm to remind the user that there is a refrigerant leak.

[0066] Combined with Figure 1 and Figure 2 , in some embodiments, for the convenience of wire routing, the air conditioner further includes an electric control component 80, and the electric control component 80 and the second refrigerant detector 30 are located on the same side of the heat exchanger 20. Among them, the electric control component 80 includes a controller.

[0067] In some embodiments, compared with the electric control component 80 and the second refrigerant detector 50 being respectively located on the opposite sides of the heat exchanger 20, the electric control component 80 and the second refrigerant detector 50 are located on the same side of the heat exchanger 20, so that the second refrigerant detector 50 is close to the electric control component 80, reducing the distance between the second refrigerant detector 50 and the electric control component 80, facilitating the electrical connection between the second refrigerant detector 50 and the electric control component 80 and facilitating wire routing.

[0068] Combined with Figure 1 and Figure 2 , in some embodiments, the heat exchange box body 10 includes a second side plate 103 opposite to the first side plate 102. Compared with the first refrigerant detector 30 being installed on the second side plate 103, the first refrigerant detector 30 is installed on the middle partition plate 101, so that the first refrigerant detector 30 is close to the electric control component 80, reducing the distance between the first refrigerant detector 30 and the electric control component 80, facilitating the electrical connection between the first refrigerant detector 30 and the electric control component 80 and facilitating wire routing.

[0069] Combined with Figure 1 and Figure 2, in some embodiments, to further facilitate the installation of the first refrigerant detector 30, along the air outlet direction, the projections of the first refrigerant detector 30 and the driver 701 on the middle partition 101 at least partially overlap, and the first refrigerant detector 30 and the driver 701 are respectively located on two opposite sides of the middle partition 101. Wherein, the driver 701 is the motor of the fan assembly 70.

[0070] In some embodiments, the driver 701 is installed on the middle partition 101, and the middle partition 101 supports the driver 701. To ensure the stability of the middle partition 101 in supporting the driver 701, a relatively large installation area needs to be planned on the middle partition 101 to install the driver 701. The first refrigerant detector 30 and the driver 701 are respectively located on two opposite sides of the middle partition 101. Along the air outlet direction, the projections of the first refrigerant detector 30 and the driver 701 on the middle partition 101 at least partially overlap. That is to say, the first refrigerant detector 30 can make full use of the installation area of the driver 701, improving the space utilization rate.

[0071] In some embodiments, to improve the detection efficiency and accuracy, the heat exchange cabinet 10 further includes a chassis. The first refrigerant sensor 30 is located between the heat exchanger 20 and the chassis. When refrigerant leakage occurs in the heat exchange cabinet 10, under the action of gravity, the refrigerant will fall towards the chassis. During the falling process, the first refrigerant sensor 30 can detect the leaked refrigerant, enabling timely detection of refrigerant leakage, improving the detection efficiency and also the detection accuracy.

[0072] Based on the same inventive concept, the present application also proposes an air conditioner that employs the above-mentioned heat exchange assembly. The specific structure of the heat exchange assembly refers to the above embodiments. Since all the technical solutions of the above embodiments are adopted, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0073] In some embodiments, the air conditioner can be a duct machine, a wall-mounted air conditioner, a ceiling-mounted air conditioner, etc. The present application does not make any restrictions.

[0074] Combined Figure 1 and Figure 2 , in some embodiments, the air conditioner includes a fan assembly 70 and a compressor. The controller is electrically connected to the fan assembly 70 and the compressor. When the alarm goes off, the controller controls the fan assembly 70 to operate at the maximum wind speed and controls the compressor to stop running. At this time, the fan assembly 70 can blow out the refrigerant in the heat exchange cabinet 10 to prevent the refrigerant from accumulating in the heat exchange cabinet 10 and ensure user safety.

[0075] In some embodiments, when the fan assembly 70 is operating, even if there is a refrigerant leakage, the fan assembly 70 can blow out the refrigerant in the heat exchange box 10 to prevent the refrigerant from accumulating in the heat exchange box 10 and ensure user safety. At this time, the first refrigerant detector 30 and the second refrigerant detector 50 may not perform detection. When the fan assembly 70 stops operating, the first refrigerant detector 30 and the second refrigerant detector 50 are started so that the first refrigerant detector 30 and the second refrigerant detector 50 detect the refrigerant to determine whether there is a refrigerant leakage.

[0076] In some embodiments, after the repair of the refrigerant leakage is completed, the fan assembly 70 stops operating, and the first refrigerant detector 30 and the second refrigerant detector 50 are started. The first refrigerant detector 30 detects the concentration value of the third refrigerant in the heat exchange box 10 and sends the concentration value of the third refrigerant to the controller. The second refrigerant detector 50 detects the concentration value of the fourth refrigerant in the heat exchange box 10 and sends the concentration value of the fourth refrigerant to the controller. The controller compares the concentration value of the third refrigerant and the concentration value of the fourth refrigerant with the third set concentration value. If within the set time, either the concentration value of the third refrigerant or the concentration value of the fourth refrigerant continuously is less than the third set concentration value, it indicates that there is no refrigerant leakage in the heat exchange box 10, and the controller can control the compressor to start so that the air conditioner can perform normal refrigeration or heating work.

[0077] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0078] In addition, in the present application, the descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.
