Abstract

According to the front shell assembly and the electrical oil heater, the cover body is arranged at the opening of the mask, so that the cover body is matched with the mask to provide effective protection for the front side of the heater body. The blocking rib is arranged at one end, far away from the cover main body, of the cover body in the second direction, and the blocking rib protrudes along one side, far away from the cover main body, of the cover body in the second direction, so that when the front shell assembly is assembled on the heater body and the cover body is located above the heater body, the blocking rib protruding along the second direction can shield the heater body; water is effectively prevented from directly dripping or permeating between the heater body and the cover body, and then the water is prevented from flowing into the front shell assembly. In addition, due to the fact that the blocking ribs extend in the first direction, the blocking ribs can effectively shield the part, in the first direction, of the heater body, and meanwhile water dripping on the blocking ribs can be drained to the two sides of the heater body in the first direction conveniently. In addition, the retaining ribs are arranged on the cover body, so that the structural strength of the cover body is enhanced, the deformation of the cover body is reduced, and the gap between the cover body and the heater body is improved.

[0041] Electric oil heaters are widely loved by users because of their good heating effect and convenient heating. They usually use electric heating tubes to heat the heat-conducting oil inside the cavity of the heat sink, and use the heat sink to transfer heat to the outside to achieve the heating effect. At the same time, electric oil heaters are usually equipped with a front shell component that integrates functions such as circuit control and temperature regulation to achieve intelligent control. The front shell component is generally set on the body of the electric oil heater to protect the front side of the body. However, in traditional electric oil heaters, water seepage is prone to occur between the front shell component and the top of the body, causing electrical components in the front shell component to malfunction due to water ingress, reducing the safety of the use of the electric oil heater.

[0042] Based on this, please refer to Figures 1 to 4The present application provides a front shell assembly 100 for assembly on a radiator body 200 of an electric oil heater. The front shell assembly 100 includes a mask 10, a cover body 20 and a retaining rib 30. The mask 10 includes a mask body 11 and side portions 12 disposed on both sides of the mask body 11 along a first direction. An opening 16 is formed between one end of each side portion 12 along a height direction Z of the front shell assembly 100 and one end of the mask body 11. The cover body 20 covers the opening 16. The retaining rib 30 is disposed at one end of the cover body 20 along a second direction Y and away from the mask body 11. The retaining rib 30 protrudes on the cover body 20 along a side away from the mask body 11 and extends along the first direction X. The first direction X, the second direction Y and the height direction Z intersect in pairs, and the three directions are not coplanar.

[0043] The front shell assembly 100 is provided with a cover body 20 at the opening 16 of the mask 10, so that the cooperation between the cover body 20 and the mask 10 provides effective protection for the front side of the mask body 200. Since the retaining rib 30 is provided at one end of the cover body 20 along the second direction Y and away from the mask body 11, and the retaining rib 30 is raised along the second direction Y and along the side away from the mask body 11, when the front shell assembly 100 is assembled on the mask body 200 and the cover body 20 is located above the mask body 200, the retaining rib 30 protruding along the second direction Y can provide shielding for the mask body 200, effectively preventing water from directly dripping or penetrating between the mask body 200 and the cover body 20, and further preventing water from flowing into the interior of the front shell assembly 100. Since the retaining ribs 30 are arranged to extend along the first direction X, the retaining ribs 30 can effectively shield the portion of the radiator body 200 along the first direction X, and at the same time, it is convenient for water dripping on the retaining ribs 30 to be drained to both sides of the radiator body 200 along the first direction X. In addition, the retaining ribs 30 are arranged on the cover body 20, which is convenient for strengthening the structural strength of the cover body 20, reducing the deformation of the cover body 20, and improving the gap between the cover body 20 and the radiator body 200. With such a design, the introduction of the retaining ribs 30 is conducive to reducing the risk of water entering the front shell assembly 100, thereby improving the safety of the electric oil heater.

[0044] It should be noted that when the front shell assembly 100 is assembled on the body 200, the mask 10 is fitted on the front side of the body 200, and the cover body 20 is located above the body 200. Since the retaining rib 30 is raised on the side of the cover body 20 away from the mask body 11, there is a certain drop between the retaining rib 30 and the side of the body 200 facing the mask 10 in the second direction Y, that is, the retaining rib 30 exceeds the side of the body 200 facing the mask 10, providing shielding for the gap between the body 200 and the cover body 20, reducing the risk of water entering the interior of the front shell assembly 10. At the same time, the retaining rib 30 extends along the first direction X, which can increase the shielding range of the body 200 in the first direction X, and also facilitates the drainage of water to both sides of the body 200.

[0045] There are many ways to fix the rib 30 on the cover 20, such as but not limited to welding, clamping, riveting, bolting, etc.; the rib 30 and the cover 20 can also be designed as an integrated structure, such as injection molding, die casting, 3D printing, etc. At the same time, there are also many ways to fix the cover 20 at the opening 16 of the mask 10, such as bolting, clamping, magnetic attraction, etc.

[0046] It should also be noted that when the cover body 20 is covered at the opening 16, the cover body 20 will be fixed to the two side portions 12. Therefore, the force on both sides of the cover body 20 is relatively large, resulting in a slight deformation of the middle part of the cover body 20 in the first direction X, thereby increasing the gap between the cover body 20 and the cover body 200. At this time, water will penetrate from the deformation, thereby causing the risk of water entering the front shell assembly 100. For this reason, the present application sets a retaining rib 30 at one end of the cover body 20 away from the cover body 11, and the retaining rib 30 extends along the first direction X, which can enhance the structural strength of the cover body 20 between the two side portions 12, improve the problem of deformation of the cover body 20, and further reduce the probability of water entering the front shell assembly 100.

[0047] In addition, in some embodiments, the first direction X, the second direction Y, and the height direction Z are perpendicular to each other.

[0048] For further information, please refer to Figure 4 The retaining rib 30 includes a main body 31 and drainage portions 32 respectively arranged at both ends of the main body 31 along the first direction X. The drainage portion 32 is bent relative to the main body 31 along the height direction Z and toward one side of the mask 10. It can be seen that when the mask 10 is covered on the radiator body 200 and the cover body 20 is located above the radiator body 200, the drainage portion 32 is bent relative to the main body 31 toward one side of the radiator body 200, so that water dripping on the main body 31 is more likely to flow to the drainage portion 32. Since the two drainage portions 32 are located at both ends of the main body 31 along the first direction X, the water on the drainage portion 32 is more likely to drip from one side of the radiator body 200 along the first direction X, which effectively reduces the probability of water flowing from the middle position of the radiator body 200 into the interior of the front shell assembly 100, thereby improving the safety of the electric oil heater.

[0049] It should be noted that the two drainage portions 32 are respectively located at the two ends of the main body 31 along the first direction X, so that when the cover 20 is located above the tread 200, it can be ensured that the end of each drainage portion 32 away from the main body 31 can extend out of the side of the tread 200 along the first direction X, so that the drained water will not drip on the tread 200. Specifically in some embodiments, the projection of the drainage portion 32 along the height direction Z of the front shell assembly 100 exceeds the corresponding side of the tread 200 along the first direction X or is flush with the corresponding side of the tread 200 along the first direction X.

[0050] At the same time, the drainage portion 32 is bent relative to the main body 31 along the height direction Z and toward one side of the mask 10. It can be understood that when the front shell assembly 100 is assembled on the body 200, the drainage portion 32 is bent relative to the main body 31 toward the ground, so that the water dripping on the main body 31 is drained to the ground. The drainage portion 32 can be designed as an arc structure, with its concave surface facing one side of the mask 10; or the drainage portion 32 can also be designed as an inclined structure, and a certain angle is formed between the drainage portion 32 and the main body 31.

[0051] Optionally, there are various ways to connect each drainage portion 32 with the main body portion 31, such as but not limited to bonding, clamping, riveting, welding, etc.; or, each drainage portion 32 and the main body portion 31 are an integrated structure.

[0052] In some embodiments, please refer to Figure 5 , the length of the retaining rib 30 in the first direction X is recorded as L, wherein 8mm≤L≤12mm. It can be seen from this that if the length of the retaining rib 30 in the first direction X is too long, it is easy to break when falling because the retaining rib 30 has no supporting structure; if it is too short, it cannot play an effective shielding role. For this reason, the application controls the length of the retaining rib 30 in the first direction X to be between 8mm and 12mm, for example: it can be but not limited to 8mm, 9mm, 10mm, 11mm, 12mm, etc. With such a design, the size of the retaining rib 30 in the first direction X is reasonably controlled, which is conducive to taking into account both the structural stability and shielding effect of the retaining rib 30.

[0053] In some embodiments, please refer to Figure 6 and Figure 7 , a first folded edge 111 is provided on one end of the cover body 11 and protrudes toward the opening 16, a plug-in component 21 is provided on one side of the cover body 20 facing the opening 16, and an insertion gap 22 is provided between the plug-in component 21 and the cover body 20, and the first folded edge 111 is inserted into the insertion gap 22. It can be seen that during the assembly process, the insertion gap 22 of the cover body 20 can be aligned with the first folded edge 111; then the cover body 20 is pushed along the second direction Y so that the first folded edge 111 is inserted into the insertion gap 22, so that the cover body 20 can be quickly assembled at the opening 16, thereby improving the assembly efficiency.

[0054] It should be noted that the number of connectors 21 can be one or more. When there are more than one connectors 21, the insertion gaps 22 on each connector 21 can be inserted into the same first folded edge 111, which can increase the connection points between the cover body 20 and the cover body 11, and is beneficial to improving the structural stability of the front shell assembly 100.

[0055] The first folded edge 111 can extend along the first direction X on the cover body 11, so that when the first folded edge 111 is inserted into the insertion gap 22, the cover body 20 and the first folded edge 111 have an overlapping portion, which reduces the gap between the cover body 11 and the cover body 20 and improves the waterproof performance of the structure. At the same time, there are many ways to connect the plug-in 21 to the cover body 20, such as but not limited to bolt connection, clamping, riveting, welding, etc.; of course, the two can also be set as an integrated structure.

[0056] In some embodiments, please refer to Figure 7 and Figure 8 At least one side portion 12 is provided with a second folded edge 121 protruding toward the opening 16, and one of the second folded edge 121 and the cover body 20 is provided with a buckle groove 122, and the other is provided with a snap-fitting member 23 that snaps with the buckle groove 122. It can be seen that when the cover body 20 is covered at the opening 16, the buckle groove 122 can be matched with the snap-fitting member 23, so that the cover body 20 can be quickly snap-fitted on one end of the side portion 12.

[0057] The buckle groove 122 may be provided on the second folded edge 121, and the clamping member 23 may be provided on the cover body 20; or the clamping member 23 may be provided on the second folded edge 121, and the buckle groove 122 may be provided on the cover body 20. In some embodiments, the buckle groove 122 is provided on the second folded edge 121, and the clamping member 23 is provided on the cover body 20. When the cover body 20 is covered at the opening 16, the clamping member 23 is inserted into the buckle groove 122 and clamped on the periphery of the buckle groove 122.

[0058] Meanwhile, when both side portions 12 are provided with second folded edges 121, the cover body 20 is engaged with the buckle groove 122 through the clamping member 23 and is clamped on the two second folded edges 121. Such a design can further improve the stability of the structure of the front housing assembly 100.

[0059] Optionally, there are various ways to connect the clamping member 23 to the cover body 20 or the second folded edge 121, such as but not limited to bolt connection, clamping, riveting, welding, etc.; of course, the two can also be set as an integrated structure.

[0060] In addition, in some embodiments, please refer to Figure 6 and Figure 7, the cover body 20 is provided with a snap-in piece 23 and a plug-in piece 21, and a plug-in gap 22 is provided between the plug-in piece 21 and the cover body 20. The cover body 11 is provided with a first folded edge 111 protruding toward the opening 16, and at least one side portion 12 is provided with a second folded edge 121 protruding toward the opening 16, and a buckle groove 122 is provided on the second folded edge 121. In this way, when the cover body 20 is covered at the opening 16, the plug-in gap 22 can be aligned with the first folded edge 111, so that the first folded edge 111 is inserted into the plug-in gap 22; then, the cover body 20 is pressed down so that the snap-in piece 23 is snapped into the buckle groove 122, so that the cover body 20 is snapped onto the side portion 12. Such a design not only improves the assembly convenience between the cover body 20 and the mask 10; but also further improves the bonding force between the cover body 20 and the mask 10, thereby improving the structural stability of the front shell assembly 100.

[0061] In some embodiments, please refer to Figure 2 The front shell assembly 100 also includes a protective cover 14. At least one of the cover body 11 and the two side parts 12 is provided with a through hole 13. The protective cover 14 is provided on the through hole 13, and a vent 141 communicating with the through hole 13 is provided on the side of the protective cover 14 facing away from the cover body 20. It can be seen that since the vent 141 is provided on the side of the protective cover 14 facing away from the cover body 20, when the front shell assembly 100 is assembled on the cover body 200, the vent 141 is provided toward the ground, so that the water dropped or drained from the cover body 20 will not enter the through hole 13 through the vent 141 under the protection of the protective cover 14, thereby achieving effective waterproofing. At the same time, the vent 141 is kept in communication with the through hole 13 to ensure sufficient air exchange between the inside of the front shell assembly 100 and the outside world, thereby achieving improved thermal efficiency.

[0062] It should be noted that the through hole 13 can be provided on one of the side portions 12; can also be provided on both side portions 12; of course, can also be provided separately on the cover body 11, etc. Specifically in some embodiments, both side portions 12 are provided with through holes 13, and each through hole 13 is covered with a protective cover 14. Among them, on each side portion 12, the number of through holes 13 can be multiple, and the distribution of each through hole 13 on the side portion 12 can be multiple, for example: all through holes 13 are distributed at intervals along the height direction Z; or, distributed at intervals along the second direction Y, etc.

[0063] It should also be noted that there are many ways to fix the protective cover 14 on the through hole 13, such as bolt connection, clamping, welding, etc.; the protective cover 14 can also be fixed on the through hole 13 by an integral molding method.

[0064] In some embodiments, please refer to Figures 9 to 11The front housing assembly 100 further includes a panel 40 and a switch component 50. The panel 40 is embedded in the housing body 11. The panel 40 is provided with a mounting hole 42. The switch component 50 is embedded in the mounting hole 42 and is snap-fitted with the panel 40. With such a design, during assembly, the switch component 50 can be embedded in the mounting hole 42 and snap-fitted to the panel 40 stably, which not only improves assembly efficiency but also improves installation stability of the switch component 50.

[0065] It should be noted that there are various ways of snapping the switch component 50 and the panel 40. For example, a spring structure may be provided in one of the switch component 50 and the panel 40, and the switch component 50 may be elastically snapped onto the panel 40 by utilizing the spring structure. Alternatively, a groove structure may be provided in one of the switch component 50 and the panel 40, and a convex structure cooperating with the groove structure may be provided in the other of the switch component 50 and the panel 40.

[0066] For specific embodiments, please refer to Fig.12 and Fig.13 , the switch component 50 is provided with a snap-on spring piece 56 on opposite sides, and the snap-on spring piece 56 includes an elastic portion 561 and a snap-on portion 562 connected to the elastic portion 561, and the elastic portion 561 and the snap-on portion 562 are sequentially distributed along the plugging direction of the switch component 50, and the two ends of the elastic portion 561 and the snap-on portion 562 that are away from each other are respectively connected to the switch component 50, and the distance between the elastic portion 561 and the switch component 50 gradually increases from the end of the elastic portion 561 away from the snap-on portion 562 to the end of the elastic portion 561 close to the snap-on portion 562. In this way, when the switch component 50 is inserted into the mounting hole 42, the elastic portion 561 gradually abuts against the hole wall of the mounting hole 42 and deforms until the abutting portion abuts against the hole wall of the mounting hole 42, so as to complete the elastic snap-on of the switch component 50.

[0067] At the same time, there are also many ways to fix the panel 40 on the cover body 11, such as but not limited to clamping, riveting, bolting, etc. When the panel 40 is fixed to the cover body 11 in a clamping manner, the assembly efficiency of the panel 40 on the cover body 11 can be improved. Specifically, in some embodiments, the cover body 11 is provided with a fixing hole 15, and the panel 40 is provided with a buckle 41, and the buckle 41 is used to fix the panel 40 on the cover body 11 stably and quickly.

[0068] For further information, please refer to Fig.13The switch component 50 includes a base 51, a pressure cover 54, a waterproof cap 53 and a switch element 52 arranged on the base 51. The base 51 is embedded in the mounting hole 42 and clamped with the panel 40. The waterproof cap 53 is covered at one end of the base 51 outside the mounting hole 42. The pressure cover 54 is sleeved outside the waterproof cap 53 and presses the waterproof cap 53 on the base 51, and one end of the pressure cover 54 abuts on the panel 40. It can be seen that when the base 51 is embedded in the mounting hole 42, the waterproof cap 53 can be covered on one end of the base 51 to close one end of the base 51. At the same time, the waterproof cap 53 is pressed on the base 51 by the pressure cover 54, so that the waterproof cap 53 and the base 51 are closely combined, providing a closed environment for the switch element 52 in the base 51, and achieving effective waterproofing. At the same time, one end of the pressure cover 54 abuts on the panel 40, which can also seal the gap between the base 51 and the hole wall of the mounting hole 42.

[0069] It should be noted that when the pressure cover 54 is sleeved outside the waterproof cap 53, it can also be connected to the waterproof cap 53 to increase the connection between the pressure cover 54 and the waterproof cap 53, for example, the pressure cover 54 and the waterproof cap 53 can be connected by a snap-fit ​​method. At the same time, the pressure cover 54 can also be installed on the panel 40 by a snap-fit ​​method; it can also be fixed on the panel 40 by an interference fit method, such as the panel 40 is provided with a groove structure, and the pressure cover 54 is interference fit in the groove structure.

[0070] In addition, the front housing assembly 100 further includes a thermostat 55 and an in-machine wiring 60. The thermostat 55 may be disposed on the panel 40, and the in-machine wiring 60 is located in the mask 10. Meanwhile, the switch element 52 refers to the control of disconnecting or connecting the power of the electric oil heater, which may be, but is not limited to, a rocker switch.

[0071] In some embodiments, please refer to Fig.13The pressure cover 54 includes a pressing part 541 and a first surrounding edge part 542 arranged around the pressing part 541. The waterproof cap 53 includes a cap body 531 and a second surrounding edge part 532 arranged around the cap body 531. The cap body 531 covers one end of the base 51. The second surrounding edge part 532 is arranged around the outer periphery of the base 51. The pressing part 541 is sleeved outside the cap body 531 and presses the cap body 531 onto the base 51. The first surrounding edge part 542 is arranged around the second surrounding edge part 532, and the second surrounding edge part 532 extends out of the first surrounding edge part 542. It can be seen that when the first surrounding edge part 542 and the second surrounding edge part 532 are both pressed onto the panel 40, since the second surrounding edge part 532 extends out of the first surrounding edge, the second surrounding edge part 532 is preferentially abutted against the panel 40 and undergoes structural deformation. When the first surrounding edge portion 542 abuts against the panel 40, one end of the second surrounding edge portion 532 is deformed, so that the deformed end of the second surrounding edge portion 532 is expanded and tightened between the first surrounding edge portion 542 and the base 51, increasing the bite force between the pressure cover 54 and the base 51, thereby improving the bonding force between the pressure cover 54 and the base 51 of the waterproof cap 53, thereby facilitating meeting the safety tensile test of the waterproof cap 53. In addition, the deformed second surrounding edge portion 532 is tightly abutted against the panel 40, which can further improve the bonding force between the waterproof cap 53 and the panel 40, which is conducive to improving the waterproof performance.

[0072] It should be noted that, in order to facilitate the cap body 531 to abut against the base 51 more stably, the cap body 531 may include a covering portion 53a and a connecting portion 53b circumferentially connected to the covering portion 53a, and the second surrounding edge portion 532 is connected to the connecting portion 53b. The pressing portion 541 presses the connecting portion 53b onto the base 51.

[0073] For further information, please refer to Fig.13 , the dimension of the second surrounding edge portion 532 extending outside the first surrounding edge portion 542 is recorded as h, where 4mm≤h≤8mm. It can be seen from this that in order to prevent contact with the switch element 52 on the base 51, the waterproof cap 53 should meet the safety tensile requirements. For example: in the experiment, a tensile force is applied to the waterproof cap 53 and lasts for 10s. The tensile force can meet 30N to determine whether the waterproof cap 53 is pulled out. If the dimension of the second surrounding edge portion 532 extending outside the first surrounding edge portion 542 is shorter, the bite force between the pressure cover 54 and the base 51 will be too small, resulting in the tensile test of the waterproof cap 53 not meeting the safety tensile requirements. If it is extended too long, the waterproof cap 53 and the pressure cover 54 cannot be effectively installed on the panel 40.

[0074] To this end, in this embodiment, the dimension of the second peripheral edge portion 532 extending outside the first peripheral edge portion 542 is controlled to be between 4 mm and 8 mm, for example, but not limited to 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc. In this way, the waterproof cap 53 can be effectively installed and fixed while also meeting the safety tensile test requirements.

[0075] In some embodiments, please refer to Fig.11 and Fig.13 , a recessed groove 43 is provided on the panel 40, and the mounting hole 42 is provided on the bottom wall of the recessed groove 43. One end of the pressure cover 54 and the waterproof cap 53 are both in contact with the bottom wall of the recessed groove 43 located at the outer periphery of the mounting hole 42, and the side of the pressure cover 54 facing away from the waterproof cap 53 is in contact with the side wall of the recessed groove 43. It can be seen that the recessed groove 43 is provided on the panel 40, so that the pressure cover 54 and the waterproof cap 53 are fixed in the recessed groove 43. At the same time, the pressure cover 54 is stably fixed in the recessed groove 43 in an interference fit manner, thereby improving the stability of the switch component 50 installed on the panel 40.

[0076] In some embodiments, please refer to Fig.14 The present application provides an electric oil heater, which includes a heater body 200 and a front shell assembly 100 as described above. The mask 10 is disposed on one side of the heater body 200 along the second direction Y, and the cover body 20 is located above the heater body 200 along the height direction Z of the front shell assembly 100.

[0077] The above-mentioned electric oil heater adopts the above-mentioned front shell assembly 100, and the cover body 20 is arranged at the opening 16 of the mask 10, so that the cooperation between the cover body 20 and the mask 10 provides effective protection for the front side of the heater body 200. Since the retaining rib 30 is arranged at one end of the cover body 20 along the second direction Y and away from the cover body 11, and the retaining rib 30 is raised along the second direction Y and along the side away from the cover body 11, therefore, when the front shell assembly 100 is assembled on the heater body 200, and the cover body 20 is located above the heater body 200, the retaining rib 30 protruding along the second direction Y can provide shielding for the heater body 200, effectively preventing water from directly dripping or penetrating between the heater body 200 and the cover body 20, and further preventing water from flowing into the interior of the front shell assembly 100. Since the retaining ribs 30 are arranged to extend along the first direction X, the retaining ribs 30 can effectively shield the portion of the radiator body 200 along the first direction X, and at the same time, it is convenient for water dripping on the retaining ribs 30 to be drained to both sides of the radiator body 200 along the first direction X. In addition, the retaining ribs 30 are arranged on the cover body 20, which is convenient for strengthening the structural strength of the cover body 20, reducing the deformation of the cover body 20, and improving the gap between the cover body 20 and the radiator body 200. With such a design, the introduction of the retaining ribs 30 is conducive to reducing the risk of water entering the front shell assembly 100, thereby improving the safety of the electric oil heater.

[0078] It should be noted that the electric oil heater also includes a heating component 300 and a stopper, and the heating component 300 is used to heat the inside of the heater body 200. At the same time, the electric oil heater may also include a rolling component 400, which is arranged at the bottom of the heater body 200 to make the electric oil heater move smoothly.

[0079] For further information, please refer to Fig.15 The body 200 includes a plurality of heat sinks 210 sequentially arranged along the second direction Y, the heat sink 210 includes a first heat sink 211 located at one end of the second direction Y, the mask 10 is disposed on one side of the first heat sink 211, the cover 20 is located above the first heat sink 211, and the end of the retaining rib 30 away from the cover body 11 exceeds the top of the first heat sink 211 in the second direction Y. It can be seen that the end of the retaining rib 30 away from the cover body 11 exceeds the top of the first heat sink 211 in the second direction Y, providing shielding for the body 200, effectively preventing water from directly dripping or penetrating between the body 200 and the cover 20, and further preventing water from flowing into the interior of the front shell assembly 100.

[0080] It should be noted that the structure of the first heat sink 211 introduced in this embodiment is the same as that of the heat sink 210 , and this concept is introduced to facilitate distinguishing the heat sink 210 assembled in the front housing assembly 100 .

[0081] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
