[0002] The reactor is an important component of the heat pump electronic control system. It can convert the alternating current in the heat pump circuit system into direct current to obtain a more stable circuit system, thereby allowing the heat pump to work in a more stable circuit system.

[0003] Existing heat pumps usually place the reactor in a closed compressor cavity, or additionally place a closed electrical box in the heat pump to place the reactor, thereby improving the waterproofness of the reactor. However, the reactor is large in size and heavy in weight, and it also generates a lot of heat during operation. The closed structure of the electrical box or compressor cavity is not conducive to the heat dissipation of the reactor, and may even affect the reliability and life of the reactor. Therefore, the temperature rise problem of the reactor in the heat pump is a difficult problem that needs to be solved in this field. Utility Model Content

By arranging the reactor on the side of the mounting frame away from the fan, the reactor is counterweighted with the two fans to improve the stability of the mounting frame. At the same time, the operation of the fan causes the air behind the fan to flow quickly through the reactor, taking away the heat generated by the reactor, and then convecting with the fan air and the external air to continuously dissipate the heat on the surface of the reactor, effectively accelerating the heat dissipation of the reactor, and allowing the reactor to work stably in a low-temperature environment.

The second air guiding members protrude outside the anti-reactive cover. The second air guiding member includes a second louver and a second through hole. The second through hole penetrates the side surface of the anti-reactive cover and communicates with the second louver.

[0015] Further, a wire passing hole and a wire pressing portion are provided on the side surface of the anti-reactive cover. The wire passing hole allows the wire connecting the reactor to pass through. The wire pressing portion is fixedly provided on the side surface of the anti-reactive cover and is located below the wire passing hole. The wire forms a bend through the wire pressing portion; a waterproof plug is installed in the wire passing hole.

[0016] Further, the outer diameter of the fan is greater than the width of the mounting frame.

[0017] Further, the mounting frame includes a first connecting portion, a second connecting portion, columns and a connecting frame. There are at least two columns. At least two columns are relatively spaced and connected between the first connecting portion and the second connecting portion. The fan is fixedly provided on the columns through the connecting frame. The outer diameter of the fan is greater than the width and / or length of the support frame; the base is fixedly provided on the side of the column away from the fan and is located between two adjacent support frames.

[0018] On the other hand, the present invention also provides a heat pump including the above-mentioned reactor heat dissipation and waterproof structure.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) By separately arranging the reactor and the fan on both sides of the mounting frame, the reactor and the fan are weighted, so that the overall center of gravity of the mounting frame is centered, the stability of the mounting frame is increased, and the overall center of gravity of the heat pump is more stable and reliable;

[0021] (2) By arranging the reactor behind the fan, when the fan rotates, the air flows through the reactor and then enters the fan or convects with the air generated by the fan, accelerating the heat dissipation of the reactor; further, by arranging the reactor between two fans, that is, at the position where the air circulation of the mounting frame or the heat pump is the largest, the heat dissipation problem can be solved to the greatest extent;

[0022] (3) By providing a first through hole for air outlet on the base and a second through hole for air inlet on the reactor cover, when the fan operates, the air inside the reactor cover flows out from the first through hole of the base, and the external air flows into the reactor cover through the second through hole of the reactor cover. Through the exchange of internal and external airflows, the surface heat of the reactor can be continuously taken away, accelerating heat dissipation;

At the same time, by setting the air outlet directions of the first louver and the second louver, the airflow entering the reactor cover can contact the reactor inside the reactor cover to the greatest extent, taking away the surface heat of the reactor, further improving the heat dissipation effect, and preventing the water vapor in the airflow and the water vapor outside the reactor cover from entering the inside of the reactor cover, improving the waterproofness of the reactor;

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "bottom", "inner", "outer", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, unless otherwise specified, "multiple" means two or more.

[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The reactor is an important component of the heat pump electronic control system. It can convert the alternating current in the heat pump circuit system into direct current to obtain a more stable circuit system, thereby allowing the heat pump to work in a more stable circuit system. Existing heat pumps are usually equipped with a fan cavity and a compressor cavity. The fan cavity is equipped with a grid to improve the heat dissipation efficiency, and the compression cavity is set as a closed structure to prevent water from entering the fan cavity through the grid. In order to prevent water from entering the fan cavity through the grid and affecting the operation of components such as the compressor, existing heat pumps usually set the reactor in a closed compressor cavity, or set an additional closed electrical box in the heat pump to place the reactor. However, the reactor is large in size and heavy in weight, and it also generates a lot of heat during operation. Therefore, the closed structure of the electrical box or compressor cavity is not conducive to the heat dissipation and maintenance of the reactor, and may even affect the reliability and life of the reactor. Therefore, the reactor in the heat pump has the problem of poor heat dissipation conditions.

[0040] Based on this, the utility model provides a reactor heat dissipation and waterproof structure, which arranges the reactor on the side of the mounting frame away from the fan, so that the reactor and the two fans are counterweighted, thereby improving the stability of the mounting frame. At the same time, the operation of the fan causes the air behind the fan to flow quickly through the reactor, taking away the heat generated by the reactor, and then convects with the fan air and the external air to continuously dissipate the heat on the surface of the reactor, effectively accelerating the heat dissipation of the reactor, and enabling the reactor to work stably in a low-temperature environment.

[0041] See also Figure 1An embodiment of the present application provides a reactor heat dissipation and waterproof structure, including a mounting frame 10 and a fan 20, wherein the fan 20 is fixedly mounted in the middle of the mounting frame 10; a reactor 30 is fixedly mounted on a side of the mounting frame 10 away from the fan, and the projections of the reactor 30 and the fan 20 on the mounting frame 10 at least partially do not overlap.

[0042] Compared with the prior art in which the reactor is arranged in a closed compressor cavity, in the embodiment of the present application, the fan 20 and the reactor 30 are respectively arranged on both sides of the mounting frame 10, so that the fan 20 and the reactor 30 are counterweighted, thereby making the center of gravity of the mounting frame 10 more stable and reliable. At the same time, when the fan 20 rotates, the air behind the fan 20 first flows through the reactor 30 and takes away the heat generated by the reactor 30 through convection heat exchange in the process of flowing toward the fan 20, and then enters the fan 20 or convects with the air supply of the fan 20, thereby improving the heat dissipation efficiency of the reactor 30. In addition, the operation of the fan 20 can form a negative pressure in the rear area of the fan 20, accelerate the flow speed of the air behind the fan 20, and further improve the heat dissipation efficiency of the reactor 30.

[0043] See also Figure 2 Further, in some embodiments, at least two fans 20 are spaced apart along the length direction of the mounting frame 10, and the reactor 30 is located between the two fans 20, so that the air flowing through the reactor 30 can have air convection with the air supplied by the two fans 20. In some embodiments, the reactor 30 is located at the upper end or the lower end of at least two fans 20, and mainly has air convection with the air supplied by one of the fans 20.

[0044] See also Figure 2-3 Furthermore, in some embodiments, the fan 20 includes a first fan 201 and a second fan 202, and the first fan 201 and the second fan 202 are respectively fixed to the upper and lower ends of the mounting frame 10 along the length direction of the mounting frame 10.

[0045] As an example, the reactor 30 is located above the first fan 201 and / or below the second fan 202 , so that air flowing through the reactor 30 undergoes air convection with wind generated by the first fan 201 and / or the second fan 202 .

[0046] As an example, the height of the reactor 30 is located between the first fan 201 and the second fan 202, so that the air flowing through the reactor 30 can enter the first fan 201 and / or the second fan 202, or have an air convection with the air generated by the rotation of the first fan 201 and / or the second fan 202. Among them, the projection of the reactor 30 on the mounting bracket 10 does not overlap at least partially with the first fan 201 or the second fan 202, or the projections of the reactor 30 on the mounting bracket 10 with the first fan 201 and the second fan 202 do not overlap. Preferably, the height of the reactor 30 is located in the middle of the heights of the first fan 201 and the second fan 202, and the projection of the reactor 30 on the mounting bracket 10 overlaps partially with the first fan 201 and / or the second fan 202. By setting the height of the reactor 30 between the first fan 201 and the second fan 202, the reactor 30 is located at the position with the largest air flow on the mounting bracket 10, so that the air flowing through the reactor 30 has a convection with the air generated by the rotation of the first fan 201 and the second fan 202, and is carried away from the mounting bracket 10 by the air generated by the rotation of the first fan 201 and the second fan 202, thus solving the heat dissipation problem of the reactor 30 to the greatest extent and making the reactor 30 work more stably.

[0047] Please refer to Figure 4-5 , further, in some embodiments, the reactor 30 includes a heating element 31 and a base 32. The heating element 31 is fixedly arranged on the base 32, and the base 32 is fixedly arranged on the side of the mounting bracket 10 away from the fan 20, that is, the first fan 201, the base 32 and the second fan 202 are arranged at intervals along the length direction of the mounting bracket 10.

[0048] Further, a plurality of first air guiding members 33 are formed on the base 32. The first air guiding members 33 protrude towards the mounting bracket 10. By arranging the first air guiding members 33, the air flowing through the reactor 30 can pass through the first air guiding members 33 and enter the fan 20 or have an air convection with the air generated by the rotation of the fan 20. Preferably, the heating element 31 is fixedly arranged in the middle of the base 32, and the first air guiding members 33 are arranged at the edges of the base 32.

[0049] Further, the first air guiding member 33 includes a first louver 331 and a first through hole 332. The first through hole 332 penetrates through the base 32 and communicates with the first louver 331. The first louver 331 is arranged perpendicular to the tangential direction of the fan 20, and the air outlet direction of the first louver 331 is opposite to the rotation direction of the adjacent fan 20.

[0050] By way of example, the height of the reactor 30 is located above the first fan 201 or below the second fan 202. The air outlet directions of the first louvers 331 are the same, and are opposite to the rotation directions of the adjacent first fan 201 or second fan 202. Specifically, when the first fan 201 and the second fan 202 are operating, they both rotate clockwise. The first louver 331 and the first through hole 332 of the reactor 30 disposed above the first fan 201 form an air flow path extending horizontally to the left from the inside to the outside, and the first louver 331 and the first through hole 332 of the reactor 30 disposed below the second fan 202 form an air flow path extending horizontally to the right from the inside to the outside.

[0051] By way of example, the height of the reactor 30 is located between the first fan 201 and the second fan 202. A plurality of first air guiding members 33 are provided at the upper and lower ends adjacent to the first fan 201 and the second fan 202 on the base 32. The air outlet directions of the plurality of first air guiding members 33 adjacent to the first fan 201 are opposite to the rotation direction of the first fan 201, and the air outlet directions of the plurality of first air guiding members 33 adjacent to the second fan 202 are opposite to the rotation direction of the second fan 202.

[0052] Further, when the first fan 201 and the second fan 202 are operating, they both rotate clockwise. The first louver 331 and the first through hole 332 of the first air guiding member 33 adjacent to the first fan 201 form an air flow path extending horizontally to the right from the inside to the outside, while the first louver 331 and the first through hole 332 of the first air guiding member 33 adjacent to the second fan 202 form an air flow path extending horizontally to the left from the inside to the outside. The first fan 201 and the second fan 202 form an air convection at their middle positions, forming the position with the largest overall air circulation of the mounting frame 10. The reactor 30 is disposed at this position, which can improve the heat dissipation efficiency of the reactor 30. At the same time, the air outlet of the base 32 forms a convection with the air supply of the first fan 201 and the second fan 202, further improving the heat dissipation efficiency of the reactor 30. Preferably, the plurality of first louvers 331 adjacent to the first fan 201 are parallel to each other, and the plurality of first louvers 331 adjacent to the second fan 202 are parallel to each other.

[0053] It can be understood that the position of the mounting frame 10 can be set according to specific requirements. In some embodiments, the mounting frame 10 is horizontally arranged, the fan 20 and the reactor 30 are arranged at intervals along the length direction of the mounting frame 10, and at least part of the projections of the reactor 30 and the fan 20 on the horizontal plane do not overlap.

[0054] Further, the number and positions of the fans 20 and the reactors 30 can be set according to specific requirements. Preferably, the reactor 30 is arranged between any two adjacent fans 20, so that the reactor 30 is located at the place where the air circulation of the entire mounting frame 10 is the largest, and the heat dissipation problem of the reactor 30 is solved to the greatest extent. In other embodiments, other heat dissipation elements can be arranged between any two adjacent fans 20.

[0055] Further, the first louver 331 is provided with a first air guiding portion 333 and a second air guiding portion 334. The first air guiding portion 333 is parallel to the base 32. The second air guiding portion 334 is connected to the first through hole 332 and the first air guiding portion 333. The second air guiding portion 334 has an arc-shaped structure to guide the gas flowing through the first louver 331. By setting the second air guiding portion 334 to have an arc-shaped structure, it can guide the air flow flowing through the second air guiding portion 334, reduce the resistance of the second air guiding portion 334 to the air flow, and improve the heat dissipation effect of the reactor 30. At the same time, the water vapor located above the first louver 331 falls along the arc-shaped second air guiding portion 334 under the action of gravity, and will not enter the reactor 30 through the first through hole 332. More preferably, the area of the first air guiding portion 333 is smaller than the area of the first through hole 332, so that the first louver 331 does not block the air flow, thereby reducing the resistance of the first louver 331 to the air flow and improving the heat dissipation effect of the reactor 30.

[0056] Please refer to Figure 4-7 , further, in some embodiments, the reactor cover 34 includes a side wall 341, a top plate 342, and a bottom plate 343. The top plate 342 is connected to the top end of the side wall 341, and the bottom plate 343 is connected to the bottom end of the side wall 341. The side wall 341 includes a first side plate 344, a second side plate 345, and a third side plate 346 connecting the first side plate 344 and the second side plate 345. A plurality of second air guiding members 35 are provided on the first side plate 344, the second side plate 345, and / or the third side plate 346. The second air guiding members 35 protrude from the first side plate 344, the second side plate 345, and / or the third side plate 346. The second air guiding members 35 include second louvers 351 and second through holes 352. The second through holes 352 penetrate through the side wall 341 of the reactor cover 34 and communicate with the second louvers 351. When the fan operates, the wind wheel of the fan rotates rapidly to form a negative pressure behind the fan. Part of the air enters the reactor cover 34 through the second air guiding members 35 on the left side, right side, and / or rear side of the reactor cover 34, flows through the reactor 30, and then flows out from the first air guiding member 33 of the base 32, and forms a convection with the air supply of the first fan 201 and / or the second fan 202, so as to dissipate heat.

[0057] Further, at least one second air guiding member 35 is located below the reactor 30, so that the contact area between the air flow flowing through the second air guiding member 35 and entering the reactor cover 34 and the reactor 30 is the largest, thereby enhancing the heat dissipation effect.

[0058] Please refer to Figure 3 Furthermore, in some embodiments, a wire passing hole 348 is provided in the side wall 341 of the reactance cover 34 for the reactance wire 36 connecting the reactor 30 to pass through. Specifically, a waterproof plug is installed in the wire passing hole 348. The waterproof plug includes a support ring and a plurality of flexible waterproof parts circumferentially arranged inside the support ring. By providing a waterproof plug in the wire passing hole 348, moisture outside the reactance cover 34 is prevented from entering the interior of the reactance cover 34 through the wire passing hole 348.

[0059] Furthermore, the reactance wire 36 of the reactor 30 is connected to the electric control box and / or other components through the wire passing hole 348. In some embodiments, the reactance wire 36 is tied together with the motor wire of the fan and returns to the interior of the electric control box along the mounting bracket. The wire tying is beautiful, which can avoid the wire harness affecting the operation of other components and also avoid the interference between strong and weak electricity affecting the electromagnetic compatibility (EMC) test, improving the anti-interference ability of the structure.

[0060] Furthermore, the reactor 30 further includes a wire pressing part 37. The wire pressing part 37 includes a first assembly part 371 and a second assembly part 372. The first assembly part 371 is connected to the reactance wire 36, and the second assembly part 372 is fixed outside the reactance cover 34 and is located below the wire passing hole 348, causing the reactance wire 36 to form a bend outside the reactance cover 34. By forming the bend, moisture outside the reactance cover 34, especially the water above the wire passing hole 348, is prevented from flowing along the reactance wire 36 into the interior of the reactance cover 34 under the action of gravity. Specifically, the first assembly part 371 is an assembly hole, and the reactance wire 36 passes through the assembly hole to connect the wire pressing part 37 and the reactance wire 36. The second assembly part 372 is locked to the side wall 341 of the reactance cover 34 through a locking member. Preferably, two wire pressing parts 37 are provided. One of the wire pressing parts 37 is arranged below the wire passing hole 348 and is located on the left or right side of the other wire pressing part 37, so that the reactance wire 36 forms a return bend outside the reactance cover 34. In other embodiments, more than two wire pressing parts 37 can be provided, and some of the wire pressing parts 37 are fixed on the mounting bracket 10 to connect the reactance wire 36 and the motor wire to the mounting bracket 10.

[0061] Furthermore, the wire passing hole 348 is opened at the upper end of the side wall 341 of the reactance cover 34 and is located above the second air guiding member 35. Preferably, the wire passing hole 348 is provided on the first side plate 344 or the second side plate 345, so that the reactance wire 36 is close to the mounting bracket 10, with beautiful wiring and avoiding interference with the operation of other components.

[0062] Furthermore, the outer edge of the fan 20 protrudes from both ends of the mounting bracket 10, that is, the outer diameter of the fan 20 is greater than the width of the mounting bracket 10, so that the air behind the fan 20 can enter the fan 20 from the areas where the fan 20 protrudes from both ends of the mounting bracket 10, promoting the formation of a negative pressure on the side of the mounting bracket 10 away from the fan 20 and improving the heat dissipation efficiency of the reactor 30.

[0063] Further, the mounting frame 10 includes a first connecting portion 11, a second connecting portion 12, and columns 13. There are at least two columns 13, and the at least two columns 13 are connected to each other at intervals between the first connecting portion 11 and the second connecting portion 12. Preferably, the at least two columns 13 are perpendicularly connected to the first connecting portion 11 and the second connecting portion 12, that is, the first connecting portion 11 and the second connecting portion 12 are parallel.

[0064] Further, the mounting frame 10 further includes at least two support frames 14. The at least two support frames 14 are fixedly provided on the at least two columns 13 along the length direction of the mounting frame 10. The outer diameter of the fan 20 is greater than the width and / or length of the support frame 14, so that the air behind the fan 20 can enter the fan 20 from the outside of the support frame 14, which is more conducive to the heat dissipation of the reactor 30 behind the fan 20. The base 32 is fixedly provided on the at least two columns 13, and the orthographic projections of the base 32 and the support frame 14 on the plane where the at least two columns 13 are located do not overlap. The support frame 14 and the at least two columns 13 can be fixedly connected by welding, or directly locked by a locking member.

[0065] Further, the fan 10 is composed of a wind wheel and a motor. The motor is arranged on the mounting frame 10 through the support frame 14. Specifically, the motor is locked to the support frame 14 by a locking member. The edge of the support frame 14 is bent towards the mounting frame 10 to form a bending portion, and the bending portion is fixedly connected to the mounting frame 10.

[0066] Please refer to Figure 4 , further, in some embodiments, there are a pair of columns 13, and the left and right edges of the base 32 are bent towards the mounting frame 10 to form a first bending portion 321.

[0070] Please refer to Figure 8 , The present utility model further provides a heat pump, which includes a chassis 40, fins 41, a middle partition plate 42, and the above-mentioned reactor heat dissipation and waterproof structure. The middle partition plate 42 is fixedly arranged at the bottom of the chassis 40, dividing the interior of the chassis 40 into a fan chamber and a compression chamber, and the reactor heat dissipation and waterproof structure is arranged in the fan chamber.

[0071] The reactor heat dissipation and waterproof structure in this embodiment can have the same structure and achieve the same effect as the reactor heat dissipation and waterproof structure in the above embodiment, and will not be described in detail in this embodiment.

[0072] In some embodiments, a highly integrated pre-installation method is adopted to install the reactor heat dissipation and waterproof structure and / or the heat pump to reduce the installation difficulty and labor cost.

[0073] The working principle of the reactor heat dissipation and waterproof structure of the present utility model is as follows:

[0074] When the heat pump is operating, the first fan 201 and the second fan 202 rotate in the clockwise direction. The rapid rotation of the wind wheels enables air exchange between the inside and outside of the heat pump, and at the same time creates a negative pressure on the side of the mounting bracket 10 away from the fans behind the fans, causing air to move forward rapidly. As a result, the air inside the reactance cover 34 flows out through the first air guiding member 33 and moves to the first fan 201 and / or the second fan 202. The air outside the reactance cover 34 enters the inside of the reactance cover 34 through the second air guiding member 35 and contacts the heating element 31 in the reactance cover 34, taking away the heat generated by the heating element 31. The left, right, and rear sides of the reactance cover 34 intake air, and the base 32 exhausts air. The exchange of internal and external airflows continuously takes away the heat on the surface of the heating element 31, thereby improving the heat dissipation effect of the reactor 30. In addition, the reactor 30 is located between the first fan 201 and the second fan 202, that is, at the position with the best heat dissipation effect in the entire heat pump, causing the hot air flowing out from the first air guiding member 33 to have air convection with the air sent by the first fan 201 and / or the second fan 202, transferring the heat to the air sent by the first fan 201 and / or the second fan 202 and flowing out of the fan cavity, and contacting the external air, further improving the heat dissipation effect of the reactor 30.

[0075] Compared with the prior art, the beneficial effects of the technical solution of the present utility model are as follows:

[0076] (1) By separately arranging the reactor and the fan on both sides of the mounting bracket, the reactor and the fan are counterweighted, making the overall center of gravity of the mounting bracket centered, increasing the stability of the mounting bracket, and making the overall center of gravity of the heat pump more stable and reliable;

[0077] (2) By arranging the reactor behind the fan, when the fan rotates, air flows through the reactor and then enters the fan or has air convection with the air generated by the fan, accelerating the heat dissipation of the reactor; further, by arranging the reactor between the two fans, that is, at the position with the largest air flow in the mounting bracket or the heat pump, the heat dissipation problem can be solved to the greatest extent;

[0078] (3) By providing a first through hole for air exhaust on the base and a second through hole for air intake on the reactance cover, when the fan operates, the air inside the reactance cover flows out through the first through hole of the base, and the external air flows into the reactance cover through the second through hole of the reactance cover. Through the exchange of internal and external airflows, the heat on the surface of the reactor is continuously taken away, accelerating heat dissipation;

[0079] (4) By providing louvers with an arc-shaped structure on the base and the reactance cover, which protrude outside the base or the reactance cover, the airflow passing through the first through-hole and the second through-hole is guided, the resistance of the airflow passing through the louvers is reduced, thereby improving the heat dissipation effect of the reactor. At the same time, by setting the air outlet directions of the first louver and the second louver, the airflow entering the reactance cover can contact the reactor inside the reactance cover to the greatest extent, taking away the surface heat of the reactor, further improving the heat dissipation effect, and preventing the water vapor in the airflow and the water vapor outside the reactance cover from entering the inside of the reactance cover, improving the waterproofness of the reactor;

[0080] (5) By providing a waterproof plug in the wire passing hole and forming a water return bend of the reactance wire outside the reactance cover, it is possible to prevent the water vapor located outside the reactance cover from entering the inside of the reactance cover along the reactance wire through the gap between the wire passing hole and the reactance wire, thereby affecting the waterproofness of the reactor;

[0081] (6) By installing the reactor heat dissipation and waterproof structure and / or the heat pump in a highly integrated pre-installed manner, the installation difficulty and labor cost are reduced.

[0082] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and deformations.
