Description

Technical Field

[0001] The present invention belongs to the technical field of air-conditioning equipment, and specifically provides an air-conditioning drainage structure for a recreational vehicle. Background Art

[0002] As people's demand for driving comfort continues to increase, in-vehicle air conditioning has become an essential feature of the car cockpit. However, during the cooling process, due to the low temperature of the condenser, water in the air inside the cockpit will condense on the surface of the condenser after entering the indoor unit. This water will then flow along the condenser surface into the air conditioner chassis connected to the condenser. To prevent water in the chassis from flowing into the cockpit, it is necessary to provide a drain hole in the chassis that connects to the outside of the cockpit, allowing the condensed water to flow out of the cockpit through the drain hole. However, simply providing a drain hole in the chassis does not allow for quick and effective drainage of the water.

[0003] Some existing air conditioners have a slope structure on the chassis of the air conditioner, and a drainage hole is provided at the bottom of the slope, so that water flows to the drainage hole under the action of gravity and flows out through the drainage hole.

[0004] However, the existing air-conditioning drainage structure ignores the fact that during the operation of the vehicle, the condensed water inside the air-conditioning will also shake due to the shaking of the vehicle body, resulting in the condensed water not being able to be discharged quickly through the drainage hole. In addition, due to the shaking of the vehicle, the condensed water may fall off from the surface of the condenser or the water on the air-conditioning chassis may splash. Finally, the fallen or splashed condensed water is blown into the cockpit by the action of the air-conditioning cooling fan, reducing the user experience.

[0005] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above technical problem at least to a certain extent, that is, to solve the problem in the prior art that the air conditioner cannot quickly and effectively discharge the condensed water inside the air conditioner.

[0007] To this end, a first aspect of the present invention provides an air conditioning drainage structure for a recreational vehicle, comprising a chassis, a cover body sealed and connected to the upper part of the chassis, and a condenser installed on the chassis, the condenser being located between the chassis and the cover body, a baffle, the baffle being installed on the chassis, the outer edges of the baffle being sealed and connected to the chassis and the cover body respectively, the chassis and the cover body forming a accommodating area through the baffle, the condenser being located in the accommodating area, a first air outlet, the first air outlet being arranged on the baffle, the first air outlet having a first preset distance relative to the chassis, a first air inlet, the first air inlet being arranged at a second preset distance relative to the chassis, the first air inlet and the first air outlet being respectively located on opposite sides of the condenser, and a drainage hole, the drainage hole being arranged on the chassis and on both sides of the condenser.

[0008] When the above technical solution is adopted, a baffle is provided inside the air conditioner, and the outer edge of the baffle is sealed with the cover body and the chassis, so that the chassis and the cover body form a storage area through the baffle, and the condenser is arranged in the storage area. Through the above structure, the air entering the air conditioner from the cockpit can flow along the baffle and fully contact the condenser, thereby increasing the cooling efficiency of the condenser for the air. At the same time, the condensed water condensed on the surface of the condenser and on the surface of the baffle close to the condenser will be blocked in the storage area. Even if the condensed water shakes or splashes due to vehicle acceleration, braking, turning or bumping, the condensed water will be blocked in the storage area under the action of the baffle, and the condensed water will be discharged through the drain hole, effectively reducing the risk of condensed water entering the cockpit due to vehicle acceleration, braking, turning or bumping.

[0009] In the above-mentioned specific embodiment of the air conditioning drainage structure for RVs, the first air outlet is an air outlet tube, the tube wall of the air outlet tube is horizontally placed and protrudes a third preset distance from the baffle surface, and the top edge of the tube wall is formed into an inverted V shape.

[0010] When adopting the above technical solution, the first air outlet is configured as a horizontally placed air outlet tube, and the tube wall of the air outlet tube protrudes from the baffle surface by a third predetermined distance. This allows condensed water condensed on the baffle surface to be blocked outside the protruding tube wall as it flows downward along the baffle surface. The condensed water continues to flow downward along the top edge of the inverted V-shaped tube wall, ultimately flowing onto the receiving chassis and draining out of the cockpit through the drain hole. The use of a tube wall structure can effectively reduce the risk of condensed water entering the cockpit through the air outlet.

[0011] In the above-mentioned specific embodiment of the air conditioning drainage structure for RVs, the drainage structure also includes a water collecting plate arranged on the surface of the baffle, the water collecting plate is located on the side away from the condenser, and the water collecting plate is sealed to the cylinder wall and / or the baffle; a water inlet is provided on the baffle, and the lower edge of the water inlet is flush with the upper end surface of the water collecting plate. After entering the water collecting plate, the condensed water flows into the side of the baffle close to the condenser through the water inlet.

[0012] When the above technical solution is adopted, a water collecting plate is provided on the surface of the baffle away from the condenser, and the two sides of the water collecting plate are sealed with the cylinder wall or the baffle, so that the condensed water flowing down the surface of the baffle away from the condenser can be collected by the water collecting plate, and the collected condensed water can flow back to the accommodating area through the water inlet on the baffle, thereby collecting the condensed water on the surface of the baffle away from the condenser and discharging it to the outside of the cockpit through the drainage hole, reducing the risk of the condensed water flowing down the surface of the baffle away from the condenser being brought into the cockpit by the blown air.

[0013] In the above-mentioned specific embodiment of the air conditioning drainage structure for RVs, the chassis has an inclined surface in the accommodating area, the condenser is installed at the highest point of the inclined surface, and the drainage hole is located at the lowest point of the inclined surface.

[0014] When the above technical solution is adopted, an inclined surface is provided on the chassis, and the condenser is placed at the highest point of the inclined surface, and the drain hole is placed at the lowest point of the inclined surface. This structure enables the condensed water flowing down the surface of the condenser to quickly flow to the drain hole through the inclined surface, and then the condensed water is discharged from the drain hole to the outside of the cockpit, thereby speeding up the discharge speed of the condensed water and reducing the risk of condensed water accumulation inside the chassis.

[0015] In the above-mentioned specific embodiment of the air conditioning drainage structure for RVs, the drainage structure also includes a partition installed on the chassis, and the chassis and the cover plate are separated into a cooling area and a heat dissipation area by the partition, and the accommodating area is located in the cooling area.

[0016] In the above-mentioned specific implementation of the air conditioning drainage structure for RVs, the drainage structure further includes a cooling fan installed on the chassis, and the cooling fan is located on the chassis between the partition and the baffle.

[0017] In the above-mentioned specific implementation of the air conditioning drainage structure for RVs, a second air outlet is provided on the cover body, and the second air outlet is located above the cooling fan.

[0018] In the above-mentioned specific embodiment of the air conditioning drainage structure for RVs, the drainage structure also includes a cooling fan fixedly mounted on the chassis of the heat dissipation area, and a second air inlet and a third air outlet located on the chassis are respectively provided on both sides of the cooling fan.

[0019] In the above-mentioned specific embodiment of the air conditioning drainage structure for RVs, the drainage structure also includes a sealing gasket installed at the second air inlet, which is located outside the chassis and is used to be sealed with the vehicle body. The sealing gasket isolates the second air inlet and the drainage hole to prevent water flowing out of the drainage hole from entering the interior of the air conditioner through the second air inlet.

[0020] Another aspect of the present invention provides an air conditioner for a recreational vehicle, which adopts the drainage structure for the recreational vehicle air conditioner described in the above embodiment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may adjust them as needed to suit specific applications. For example, although the specification describes the drainage structure of a parking air conditioner, the present invention can obviously be applied to various other forms of refrigeration equipment having a condenser, as long as the condenser has the drainage structure of the present invention.

[0028] It should be noted that, in the description of the present invention, the terms "upper", "lower", "inner", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0029] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] See first Figure 1The figure shows the drainage structure of the RV air conditioner 1, which includes a chassis 14, a cover 11 sealedly connected to the upper portion of the chassis 14, and a condenser 13 mounted on the chassis 14. The condenser 13 is located between the chassis 14 and the cover 11, and a baffle 12 mounted on the chassis 14. The outer edges of the baffle 12 are sealedly connected to the chassis 14 and the cover 11, respectively, so that the chassis 14 and the cover 11 form a storage area through the baffle 12, and the condenser 13 is accommodated in the storage area. It should be noted that in some embodiments, the baffle 12 is integrally connected to the chassis 14. Specifically, the portion of the baffle 12 extending into the chassis 14 is integrally connected to the entire chassis 14. After the cover 11 is sealedly connected to the chassis 14, the inner wall of the cover 11 is sealedly connected to the outer edge of the remaining portion of the baffle 12. However, this is not restrictive, and those skilled in the art can also make the baffle 12 and the chassis 14 adopt other forms of connection structures, such as the baffle 12 and the chassis 14 have a split structure, and the outer edge of the lower end of the baffle 12 has a matching shape with the inner wall of the chassis 14. After the cover body 11 and the chassis 14 are sealed together, the inner wall of the cover body 11 can match with the outer edge of the baffle 12 and achieve a sealed connection. After the cover body 11 and the chassis 14 are sealed together, the outer edge of the remaining part of the baffle 12 can also achieve a sealed connection with the inner wall of the cover body 11. Alternatively, the baffle 12 can also be installed on the cover body 11 in a manner similar to the manner in which the baffle 12 is installed on the chassis 14, which will not be repeated here. This adjustment does not deviate from the principle of the present invention and, therefore, will fall within the scope of protection of the present invention. Based on this, the above-mentioned sealed connection structure is adopted so that the air entering the interior of the air conditioner 1 needs to be discharged through the first air outlet 121 provided on the baffle 12. Please continue to refer to Figure 1 The first air outlet 121 of the present invention is located in the lower-middle portion of the baffle 12. Specifically, the upper edge of the first air outlet 121 is spaced a first predetermined distance from the chassis 14. This ensures that air entering through the first air inlet 112 comes into contact with the condenser 13 as much as possible, thereby enhancing the cooling effect of the air conditioner 1. In practice, the first predetermined distance can be adjusted based on actual needs. The purpose of setting this first predetermined distance is to reduce the risk of condensed water on the chassis 14 being shaken or splashed and subsequently discharged from the first air outlet 121 due to vehicle acceleration, braking, cornering, or jolting.

[0031] Please continue reading Figure 1A first air inlet 112 is provided on the side wall of the cover body 11, wherein the first air inlet 112, the condenser 13 and the first air outlet 121 are located in the same space, and the condenser 13 is located between the first air inlet 112 and the first air outlet 121. Based on this, after the air inside the cockpit enters the air conditioner 1 through the first air inlet 112, it needs to pass through the condenser 13 first, and then be discharged through the first air outlet 121 after being cooled by the condenser 13. Through the above process, the air conditioner 1 realizes cooling of the cockpit air.

[0032] It will be understood by those skilled in the art that although the above Figure 1 The first air inlet 112 is described as being provided on the side wall of the cover 11, but this is not restrictive, and those skilled in the art may also provide the first air inlet 112 on the flange of the chassis 14 as needed, and such adjustment does not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention. It should be noted that in order to improve the condensation effect of the condenser 13 of the air conditioner 1, in some embodiments, the condenser 13 is provided with a preset height, and the upper edge of the condenser 13 is provided above the upper edges of the first air inlet 112 and the first air outlet 121, so that after the air in the cockpit enters the interior of the air conditioner 1 through the first air inlet 112, it can flow along the surface of the condenser 13 under the action of the baffle 12, so that the air can fully contact the surface of the condenser 13, so that the condenser 13 can cool the air in contact with it. It can be understood that the larger the area of contact between the air and the condenser 13, the better the effect of the condenser 13 on cooling the air. Based on this, the cooling effect of the condenser 13 on the air can be adjusted by adjusting the height difference between the upper edge of the first air inlet 112 and the first air outlet 121 and the upper edge of the condenser 13. This adjustment does not deviate from the principle of the present invention and therefore will fall within the scope of protection of the present invention.

[0033] Of course, the present invention does not specifically limit the number of the first air outlet 121, and one or more first air outlets 121 may be provided. When multiple first air outlets 121 are provided, continue to refer to FIG. Figure 1 and Figure 2 and Figure 3In some embodiments, to achieve better cooling efficiency for the air conditioner 1, the condenser 13 is configured in a U-shape and positioned close to the sidewalls of the chassis 14 and the cover 11. The baffle 12 also has a U-shaped structure that matches the condenser 13. This allows air entering the air conditioner 1 through the first air inlet 112 to fully contact the condenser 13 under the action of the baffle 12, thereby enhancing the condensation efficiency of the air conditioner 1. It is understood that the baffle 12 can be a U-shaped plate structure or a U-shaped plate with a flanged edge, but this is not restrictive, as long as the baffle 12 can achieve a sealed connection with the cover 11 and chassis 14. Based on this, the present invention can provide multiple first air inlets 112 on three sides of the cover 11 or chassis 14 located in the cooling zone, and multiple first air outlets 121 on the U-shaped baffle 12 to increase the ventilation volume of the air conditioner 1 during the cooling process, thereby improving the condensation efficiency of the air conditioner 1.

[0034] Please continue reading Figure 1 In some embodiments, a drainage hole 141 is provided on the chassis 14. Of course, the present invention does not specifically limit the number of the drainage holes 141. One or more drainage holes 141 may be provided. When multiple drainage holes 141 are provided, please continue to refer to Figure 3 Drain holes 141 are provided on both sides of the condenser 13 to allow condensed water flowing down the surface of the condenser 13 and the baffle 12 to drain out of the cockpit through the drain holes 141. In some embodiments, to ensure that condensed water on the chassis 14 flows quickly to the drain holes 141 and is discharged out of the cockpit through the drain holes 141, the surface of the chassis 14 in the air receiving area is configured as a sloped surface 144. The lowest points of the sloped surface 144 are located at the junction of the chassis 14 surface with the chassis 14 sidewalls and at the junction of the chassis 14 surface with the baffle 12, respectively. The condenser 13 is mounted at the highest point of the sloped surface 144. The drain holes 141 are provided at the lowest points on both sides of the sloped surface 144. This allows the condensed water on the surfaces of the condenser 13 and the baffle 12 to quickly flow to the drain holes 141 under the action of gravity and be discharged out of the cockpit through the drain holes 141, thereby improving the drainage efficiency of the air conditioner 1.

[0035] It will be understood by those skilled in the art that although the above Figure 1The description is that inclined surfaces 144 are provided on both sides of the condenser 13, and the condenser 13 is located at the highest point of the inclined surfaces 144, and the drainage holes 141 provided on both sides of the condenser 13 are located at the lowest point of the inclined surfaces 144, but this is not restrictive. Those skilled in the art can also set the inclined surfaces 144 from the connection between the baffle 12 and the chassis 14 to the connection between the chassis 14 and the edge of the chassis 14 from high to low or from low to high as needed, and the condenser 13 is set in the middle of the inclined surface 144. At this time, those skilled in the art can set the drainage hole 141 at the lowest point of the inclined surface 144 in order to increase the strength of the chassis 14, and provide a groove for the condensed water to pass through at the connection between the condenser 13 and the chassis 14, so that the condensed water can flow along the inclined surface 144 to the drainage hole 141, and finally be discharged to the outside of the chassis 14 through the drainage hole 141. This adjustment does not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0036] In addition, in the present invention, the condenser 13 is located in the accommodating area formed by the baffle 12, the cover 11 and the chassis 14. In order to increase the cooling efficiency of the air conditioner 1, the distance between the baffle 12 and the condenser 13 is made closer. Then, under the influence of the low temperature of the condenser 13, the baffle 12 will make the temperature of the baffle 12 lower than the temperature of the air inside the cockpit, and may even make the temperature of the baffle 12 lower than the temperature of the air discharged from the first air outlet 121. In this case, condensed water will also condense on the inner surface (the surface close to the condenser 13) and the outer surface (the surface away from the condenser 13) of the baffle 12. If the condensed water condensed on the inner and outer surfaces of the baffle 12 flows downward under the action of gravity, then when the condensed water passes through the first air outlet 121, it may be brought into the cockpit by the air discharged from the first air outlet 121, thereby increasing the humidity in the cockpit and reducing the user experience. In order to reduce the possibility of such a situation, the present invention sets the first air outlet 121 as a horizontally placed air outlet duct, and the tube wall 124 of the air outlet duct protrudes a third preset distance from the inner and outer surfaces of the baffle 12. In order to enable the condensed water flowing to the tube wall 124 of the air outlet duct to flow down faster, the top edge of the tube wall 124 of the air outlet duct is set to an inverted V-shaped inclined surface, but this is not restrictive. In order to make the cooling water on the top edge of the tube wall 124 flow down quickly, those skilled in the art may also set the top edge of the tube wall 124 to a circular arc surface that gradually decreases in height from the middle to both sides. This adjustment does not deviate from the principle of the present invention and therefore will fall within the scope of protection of the present invention.

[0037] Furthermore, despite the above Figure 1The described air outlet wall 124 is arranged in a horizontal direction, but this is not restrictive. In some embodiments of the present invention, in order to reduce the risk of condensed water detaching from the surface of the baffle 12 or the surface of the condenser 13 due to sudden vibration of the vehicle body and being brought into the cab under the action of the wind force of the air outlet, the first air outlet 121 of the air outlet located in the accommodating area can be set downward, and the lower edge of the air outlet wall 124 of the downward first air outlet 121 can be made to have a fourth preset distance from the chassis 14. While preventing the condensed water on the chassis 14 from being sucked up by the wind force of the downwardly arranged first air outlet 121, the water droplets of condensed water in the air can be accelerated downward under the action of gravity and wind force, and the falling water droplets can continue to fall to the surface of the chassis 14 at a speed that is not affected by the wind force when they fall to the position of the lower edge of the air outlet wall 124, thereby reducing the risk of condensation being brought into the cab due to the action of the wind force of the first air outlet 121. Such adjustments do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0038] Please continue reading Figure 1 The drainage structure of the present invention also includes a water collecting plate 122 disposed on the outer surface of the baffle 12. Both sides of the water collecting plate 122 are sealed with the cylinder wall 124 and / or the baffle 12 to collect the condensed water flowing down the outer surface of the baffle 12. This reduces the possibility of the condensed water flowing down the outer surface of the baffle 12 being carried into the cockpit by the wind blown by the cooling fan 15, and also reduces the risk of the condensed water flowing down the outer surface of the baffle 12 entering the refrigeration motor and damaging the refrigeration motor. Please continue to read Figure 1 In order to prevent the condensed water flowing down the outer surface of the baffle 12 from being collected by the water collecting plate 122 and causing the condensed water to overflow the water collecting plate 122, a water inlet 123 is opened on the baffle 12, and the lower edge of the water inlet 123 is flush with the upper end surface of the bottom plate of the water collecting plate 122, so that the condensed water entering the water collecting plate 122 can flow into the inner surface of the baffle 12 through the water inlet 123, and flow along the inner surface of the baffle 12 to the drain hole 141, and finally be discharged to the outside of the cockpit through the drain hole 141. In some embodiments, in order to make the water collecting plate 122 have a better water collecting effect, the water collecting plate 122 can be an L-shaped water collecting plate 122, or a bending portion bent toward the baffle 12 is provided on the top of the L-shaped water collecting plate 122 to reduce the risk of condensed water inside the water collecting plate 122 overflowing from the water collecting plate 122 due to acceleration, braking, turning or bumps of the vehicle. This adjustment does not deviate from the principle of the present invention and, therefore, will fall within the scope of protection of the present invention.

[0039] Please continue reading Figure 1The drainage structure of the present invention also includes a partition 16 installed on the chassis 14, and the partition 16 is arranged so that when the cover 11 is sealed with the chassis 14, the partition 16 separates the air conditioner 1 into a cooling zone and a heat dissipation zone, that is, the cooling zone is located inside the cockpit and the heat dissipation zone is located outside the cockpit through the partition 16. Specifically, the cooling zone is communicated with the cockpit so that the cooling zone cools the air inside the cockpit, and the heat dissipation zone is communicated with the outside of the cockpit so that the air in the heat dissipation zone circulates with the air outside the cockpit, thereby dissipating heat from the equipment installed in the heat dissipation zone. In some embodiments, in order to speed up the circulation speed of the air in the heat dissipation zone and the air outside the cockpit, a cooling fan 17 is installed on the chassis 14 located in the heat dissipation zone, and a second air inlet 143 connected to the outside of the cockpit is provided on the chassis 14 on one side of the cooling fan 17, and a third air outlet 142 connected to the outside of the cockpit is provided on the chassis 14 on the other side of the cooling fan 17. When the cooling fan 17 is working, the air in the heat dissipation zone is discharged to the outside of the cockpit through the third air outlet 142 due to the rotation of the fan blades of the cooling fan 17. At this time, the air pressure in the space in the heat dissipation zone is lower than the air pressure outside the cockpit. Therefore, under the action of the air pressure difference, the air outside the cockpit enters the heat dissipation zone through the second air inlet 143, thereby speeding up the circulation of the air in the heat dissipation zone and the air outside the cockpit, and further speeding up the heat dissipation speed of the heat dissipation zone.

[0040] Please continue reading Figure 1 In some specific embodiments, a cooling fan 15 is installed in the cooling area to allow the air inside the cockpit to enter the cooling area of the air conditioner 1 through the first air inlet 112, and under the action of the cooling fan 15, the cooled air is discharged from the inside of the air conditioner 1 and enters the inside of the cockpit, that is, the low-temperature air in the air conditioner 1 is circulated with the air in the cockpit through the cooling fan 15, thereby cooling the air in the cockpit. In some embodiments, the cooling fan 15 is installed on the chassis 14 between the partition 16 and the baffle 12, so that the blades of the cooling fan 15 are docked with the first air outlet 121. When the cooling fan 15 is working, the blades of the cooling fan 15 generate negative pressure at the first air outlet 121, which is used to suck out the low-temperature air on the other side of the air outlet and blow the sucked-out low-temperature air upward so that the low-temperature air enters the cockpit, thereby achieving the purpose of cooling the temperature of the air in the cockpit. It can be understood by those skilled in the art that although the above is combined with Figure 1The cooling fan 15 is described as being mounted on the chassis 14, but this is not restrictive. A person skilled in the art may also install the cooling fan 15 at the first air inlet 112 as needed. The cooling fan 15 installed at the first air inlet 112 provides power for air to enter and exit the air conditioner 1, so that the air conditioner 1 cools the air inside the cockpit. This adjustment does not deviate from the principles of the present invention and, therefore, falls within the scope of protection of the present invention. In some embodiments, a second air outlet 111 is provided on the upper portion of the cover 11, and the second air outlet 111 is located above the cooling fan 15 installed on the chassis 14, so that the cool air blown out by the cooling fan 15 can quickly enter the cockpit through the second air outlet 111.

[0041] Please continue reading Figure 1 In some embodiments, the drainage structure further includes sealing gaskets (not shown) installed at the second air inlet 143 and the third air outlet 142. These gaskets are located on the exterior of the chassis 14 and are sealed against the vehicle body, thereby reducing the risk of condensed water flowing out of the drainage holes 141 entering the heat dissipation area through the second air inlet 143 and allowing air exhausted through the third air outlet 142 to be directly discharged outside the cockpit. The chassis 14 of the present invention is also provided with a support gasket (not shown) on the exterior for supporting the chassis 14. These support gaskets are used to stably secure the chassis 14 to the bottom of the cockpit.

[0042] It should be noted that the present invention is not limited thereto. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions shall fall within the scope of protection of the present invention.
