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 heater is widely loved by users due to its good heating effect, convenient heating and other characteristics. It usually uses an electric heating tube to heat the heat-conducting oil inside the cavity of the heat-dissipating fin, and uses the heat-dissipating fin to transmit heat outward to achieve the effect of heating. At the same time, the electric oil heater is usually provided with a front shell assembly integrated with functions such as circuit control and temperature adjustment to realize intelligent control. The front shell assembly is generally arranged on the body of the electric oil heater to protect the front side of the body. However, in the traditional electric oil heater, water seepage phenomenon often occurs between the front shell assembly and the top of the body, which causes the electrical elements in the front shell assembly to malfunction due to water ingress, reducing the safety of the electric oil heater.

[0042] Based on this, please refer to Figures 1 to 4The application provides a front shell assembly 100 for assembling on a heater body 200 of an electric oil heater, the front shell assembly 100 comprising a mask 10, a cover 20 and a blocking rib 30. The mask 10 comprises a mask main body 11 and side portions 12 provided on the mask main body 11 along two sides of the mask main body 11 in a first direction X, each side portion 12 is provided with an opening 16 between one end of the side portion 12 along a height direction Z of the front shell assembly 100 and one end of the mask main body 11, and the cover 20 is provided on the opening 16. The blocking rib 30 is provided on one end of the cover 20 away from the mask main body 11 along a second direction Y, and the blocking rib 30 is protruded on a side of the cover 20 away from the mask main body 11 and extends along a first direction X, the first direction X, the second direction Y and the height direction Z are perpendicular to each other and are not coplanar.

[0043] The front shell assembly 100 described above, the cover 20 is provided on the opening 16 of the mask 10, so that the cover 20 cooperates with the mask 10 to effectively protect the front side of the heater body 200. Since the blocking rib 30 is provided on one end of the cover 20 away from the mask main body 11 along the second direction Y, and the blocking rib 30 is protruded on the side of the cover 20 away from the mask main body 11 along the second direction Y, when the front shell assembly 100 is assembled on the heater body 200 and the cover 20 is located above the heater body 200, the blocking rib 30 protruded along the second direction Y can shield the heater body 200, effectively prevent water from directly falling or seeping between the heater body 200 and the cover 20, and further prevent water from flowing into the inside of the front shell assembly 100. In addition, since the blocking rib 30 extends along the first direction X, the blocking rib 30 can effectively shield part of the heater body 200 along the first direction X, and also facilitate the water falling on the blocking rib 30 to flow to the two sides of the heater body 200 along the first direction X. In addition, the blocking rib 30 provided on the cover 20 also facilitates to strengthen the structural strength of the cover 20, reduce the deformation of the cover 20, and improve the gap between the cover 20 and the heater body 200. The design of introducing the blocking rib 30 is beneficial to reduce the risk of water entering the inside of 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 heater body 200, the mask 10 cooperates with the front side of the heater body 200, and the cover 20 is located above the heater body 200. Since the blocking rib 30 is protruded on the side of the cover 20 away from the mask main body 11, the blocking rib 30 and the side of the heater body 200 facing the mask 10 have a certain difference in the second direction Y, that is, the blocking rib 30 protrudes beyond the side of the heater body 200 facing the mask 10, thereby shielding the gap between the heater body 200 and the cover 20 and reducing the risk of water entering the inside of the front shell assembly 100. At the same time, the blocking rib 30 extends along the first direction X, which can increase the shielding range of the heater body 200 along the first direction X, and also facilitate the water to flow to the two sides of the heater body 200.

[0045] The fixing mode of the blocking rib 30 on the cover body 20 is various, such as but not limited to welding, clamping, riveting, bolt connection and the like; the blocking rib 30 and the cover body 20 can also be designed as an integrated structure, for example, by using injection molding, die casting or 3D printing to be integrally formed. Meanwhile, the fixing mode of the cover body 20 at the opening 16 of the mask 10 is also various, such as bolt connection, clamping, magnetic attraction and the like.

[0046] It should be noted that when the cover body 20 is covered at the opening 16, the cover body 20 is fixed with the two side portions 12, so that the two sides of the cover body 20 are relatively large in stress, resulting in slight deformation of the middle portion of the cover body 20 in the first direction X, thereby increasing the gap between the cover body 20 and the tank body 200. At this time, water can penetrate from the deformation, thereby causing the risk of water entering the inside of the front shell assembly 100. Therefore, the blocking rib 30 is arranged at the end of the cover body 20 away from the mask main body 11, and the blocking rib 30 extends along the first direction X, so that the structural strength of the cover body 20 between the two side portions 12 is enhanced, the deformation of the cover body 20 is improved, and the probability of water entering the inside of the front shell assembly 100 is further reduced.

[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] Further, please refer to Figure 4 The blocking rib 30 includes a main body portion 31 and a drainage portion 32 arranged at each end of the main body portion 31 along the first direction X, and the drainage portion 32 is bent relative to the main body portion 31 along the height direction Z and towards one side of the mask 10. As can be seen, when the mask 10 is covered on the tank body 200, and the cover body 20 is located above the tank body 200, the drainage portion 32 is bent relative to the main body portion 31 towards one side of the tank body 200, so that the water falling on the main body portion 31 is more likely to flow to the drainage portion 32. Since the two drainage portions 32 are located at the two ends of the main body portion 31 along the first direction X, the water on the drainage portion 32 is more likely to fall from one side of the tank body 200 along the first direction X, effectively reducing the probability of water flowing into the inside of the front shell assembly 100 from the middle position of the tank body 200, and improving the safety of the electric heating oil heater.

[0049] It should be noted that the two drainage portions 32 are respectively located at the two ends of the main body portion 31 along the first direction X, so that when the cover body 20 is located above the tank body 200, it can be ensured that the end of each drainage portion 32 away from the main body portion 31 can extend out of one side of the tank body 200 along the first direction X, so that the drained water will not fall on the tank body 200. 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 tank body 200 along the first direction X, or is flush with the corresponding side of the tank body 200 along the first direction X.

[0050] Meanwhile, the drainage portion 32 is bent relative to the main body portion 31 along the height direction Z and towards one side of the mask 10, which can be understood as that when the front shell assembly 100 is assembled on the shell body 200, the drainage portion 32 is bent relative to the main body portion 31 along the ground, so that the water falling on the main body portion 31 is drained towards the ground. The drainage portion 32 can be designed as a circular arc structure, and the concave surface thereof is arranged towards one side of the mask 10. Alternatively, 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 portion 31.

[0051] Alternatively, the connection mode between each drainage portion 32 and the main body portion 31 can be various, such as but not limited to adhesion, clamping, riveting, welding, etc. Alternatively, each drainage portion 32 and the main body portion 31 are integrated.

[0052] In some embodiments, please refer to Figure 5 The length of the blocking rib 30 in the first direction X is L, where 8mm≤L≤12mm. It can be known that if the length of the blocking rib 30 in the first direction X is too long, the blocking rib 30 is easy to break when falling due to the lack of supporting structure. If the length is too short, it cannot effectively block. Therefore, the length of the blocking rib 30 in the first direction X is controlled between 8mm and 12mm in the present application, such as but not limited to 8mm, 9mm, 10mm, 11mm, 12mm, etc. Such design reasonably controls the size of the blocking rib 30 in the first direction X, which is conducive to taking into account the structural stability and shielding effect of the blocking rib 30.

[0053] In some embodiments, please refer to Figure 6 and Figure 7 The cover body 11 is provided with a first folding edge 111 protruding towards the opening 16 at one end, the cover body 20 is provided with a plug-in part 21 on the side surface thereof towards the opening 16, the plug-in part 21 and the cover body 20 have a plug-in gap 22 therebetween, and the first folding edge 111 is inserted into the plug-in gap 22. It can be known that in the assembly process, the plug-in gap 22 of the cover body 20 can be aligned with the first folding edge 111, and then the cover body 20 is pushed along the second direction Y, so that the first folding edge 111 is inserted into the plug-in gap 22, and the cover body 20 is quickly assembled at the opening 16, improving the assembly efficiency.

[0054] It should be noted that the number of plug-in parts 21 can be one or multiple. When the plug-in parts 21 are multiple, the plug-in gaps 22 on each plug-in part 21 can be inserted into the same first folding edge 111, which can increase the combination points between the cover body 20 and the cover body 11, and is conducive to improving the structural stability of the front shell assembly 100.

[0055] The first folding edge 111 can extend along the first direction X on the cover main body 11, so that the cover body 20 has an overlapping part with the first folding edge 111 when the first folding edge 111 is inserted into the insertion gap 22, reducing the gap between the cover main body 11 and the cover body 20, and improving the waterproof performance of the structure. Meanwhile, the connection mode of the insertion part 21 on the cover body 20 has various modes, 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 With Figure 8 At least one side part 12 is provided with a second folding edge 121 protruding towards the opening 16, and the second folding edge 121 and the cover body 20 are provided with a buckle groove 122 and a clamping piece 23 matched with the buckle groove 122, respectively. Therefore, when the cover body 20 is covered at the opening 16, the cover body 20 can be quickly clamped on one end of the side part 12 by the cooperation of the buckle groove 122 and the clamping piece 23.

[0057] Among them, the buckle groove 122 can be arranged on the second folding edge 121, and the clamping piece 23 is arranged on the cover body 20; or the clamping piece 23 is arranged on the second folding edge 121, and the buckle groove 122 is arranged on the cover body 20. In some embodiments, the buckle groove 122 is arranged on the second folding edge 121, and the clamping piece 23 is arranged on the cover body 20. When the cover body 20 is covered at the opening 16, the clamping piece 23 is inserted into the buckle groove 122 and clamped on the periphery of the buckle groove 122.

[0058] Meanwhile, when both of the two side parts 12 are provided with the second folding edge 121, the cover body 20 is clamped on the two second folding edges 121 by the cooperation of the clamping piece 23 and the buckle groove 122. Such design can further improve the stability of the structure of the front shell assembly 100.

[0059] Optionally, the connection mode of the clamping piece 23 on the cover body 20 or the second folding edge 121 has various modes, 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 With Figure 7The cover body 20 is provided with a clamping piece 23 and a plug-in piece 21, and the plug-in piece 21 has a plug-in gap 22 with the cover body 20. The cover body 11 is provided with a first folding edge 111 protruding towards the opening 16, and at least one side part 12 is provided with a second folding edge 121 protruding towards the opening 16, and the second folding edge 121 is provided with a buckle groove 122. 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 folding edge 111, so that the first folding edge 111 is inserted into the plug-in gap 22; then, the cover body 20 is pressed down so that the clamping piece 23 is clamped into the buckle groove 122, so that the cover body 20 is clamped on the side part 12. This design not only improves the assembly convenience of 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, referring to Figure 2 The front shell assembly 100 further comprises 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, and the protective cover 14 is covered on the through hole 13, and a side of the protective cover 14 away from the cover body 20 is provided with a ventilation opening 141 communicating with the through hole 13. It can be seen that, since the ventilation opening 141 is arranged on the side of the protective cover 14 away from the cover body 20, when the front shell assembly 100 is assembled on the body 200, the ventilation opening 141 is arranged towards the ground, so that the water falling or flowing from the cover body 20 is prevented from entering the through hole 13 through the ventilation opening 141, thereby achieving effective waterproofing. At the same time, the ventilation opening 141 and the through hole 13 are kept in communication, which ensures sufficient air exchange between the inside of the front shell assembly 100 and the outside, thereby improving the thermal efficiency.

[0062] It should be noted that the through hole 13 can be arranged on one of the side parts 12; or can be arranged on the two side parts 12 respectively; of course, it can also be arranged on the cover body 11 alone, etc. In some embodiments, the two side parts 12 are each provided with a through hole 13, and the protective cover 14 is covered on each through hole 13. Among them, on each side part 12, the number of through holes 13 can be multiple, and the distribution of each through hole 13 on the side part 12 has multiple modes, such as: all the 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 be further noted that the protective cover 14 has multiple fixing modes on the through hole 13, such as: bolt connection, clamping, welding, etc.; or can be fixed on the through hole 13 by one-piece forming.

[0064] In some embodiments, referring to Figures 9 to 11The front shell assembly 100 further comprises a panel 40 and a switch component 50. The panel 40 is embedded on the cover main body 11, and the panel 40 is provided with a mounting hole 42. The switch component 50 is embedded in the mounting hole 42 and is clamped with the panel 40. In this way, when assembling, the switch component 50 can be embedded in the mounting hole 42, and the switch component 50 is stably clamped on the panel 40 in a clamping manner, which not only improves the assembly efficiency, but also improves the installation stability of the switch component 50.

[0065] It should be noted that there are various clamping modes between the switch component 50 and the panel 40, such as: a spring structure can be provided on one of the switch component 50 and the panel 40, and the spring structure is used to elastically clamp the switch component 50 on the panel 40; or a groove structure can be provided on one of the switch component 50 and the panel 40, and a convex structure matched with the groove structure is provided on the other one of the switch component 50 and the panel 40.

[0066] Specifically, in some embodiments, please refer to Figure 12 and Figure 13 The opposite sides of the switch component 50 are provided with clamping springs 56. The clamping spring 56 comprises an elastic portion 561 and a clamping portion 562 connected with the elastic portion 561. The elastic portion 561 and the clamping portion 562 are sequentially distributed along the insertion direction of the switch component 50. The two ends of the elastic portion 561 and the clamping portion 562 away from each other are respectively connected to the switch component 50. The distance between the elastic portion 561 and the switch component 50 gradually increases from one end of the elastic portion 561 away from the clamping portion 562 to the other end of the elastic portion 561 close to the clamping portion 562. In this way, when the switch component 50 is inserted into the mounting hole 42, the elastic portion 561 gradually deforms in abutment with the hole wall of the mounting hole 42 until the abutment portion abuts with the hole wall of the mounting hole 42 to complete the elastic clamping of the switch component 50.

[0067] Meanwhile, there are various fixing modes of the panel 40 on the cover main body 11, such as: but not limited to clamping, riveting, bolt connection, etc. When the panel 40 is fixed on the cover main body 11 in a clamping manner, the assembly efficiency of the panel 40 on the cover main body 11 can be improved. Specifically, in some embodiments, the cover main body 11 is provided with a fixing hole 15, and the panel 40 is provided with a buckling piece 41. The buckling piece 41 is used to stably and quickly fix the panel 40 on the cover main body 11.

[0068] Further, please refer to Figure 13The switch component 50 comprises a base 51, a gland 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 is clamped to the panel 40. The waterproof cap 53 is arranged on one end of the base 51 outside the mounting hole 42. The gland 54 is sleeved outside the waterproof cap 53 and is clamped to the base 51. One end of the gland 54 abuts against the panel 40. Therefore, when the base 51 is embedded in the mounting hole 42, the waterproof cap 53 can be arranged on one end of the base 51 to seal one end of the base 51. At the same time, the waterproof cap 53 is clamped to the base 51 by the gland 54, so that the waterproof cap 53 is tightly combined with the base 51 to provide a sealed environment for the switch element 52 in the base 51, thereby achieving effective waterproof. At the same time, one end of the gland 54 abuts against 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 the gland 54 can be connected with the waterproof cap 53 when it is sleeved outside the waterproof cap 53, so as to increase the connection between the gland 54 and the waterproof cap 53. For example, the gland 54 and the waterproof cap 53 can be connected in a clamping manner. At the same time, the installation of the gland 54 on the panel 40 can also be in a clamping manner, or the gland 54 can be fixed on the panel 40 in an interference fit manner, for example, the panel 40 is provided with a groove structure, and the gland 54 is interference-fitted in the groove structure.

[0070] In addition, the front shell assembly 100 further comprises a thermostat 55 and an internal wiring 60. The thermostat 55 can be arranged on the panel 40, and the internal wiring 60 is located in the mask 10. At the same time, the switch element 52 refers to the control of the power supply of the electric oil heater, which can be but is not limited to a rocker switch.

[0071] In some embodiments, please refer to Figure 13The compression cover 54 comprises a compression portion 541 and a first surrounding edge portion 542 surrounding the compression portion 541, and the waterproof cap 53 comprises a cap body 531 and a second surrounding edge portion 532 surrounding the cap body 531. The cap body 531 covers one end of the base 51, and the second surrounding edge portion 532 surrounds the outer periphery of the base 51. The compression portion 541 is sleeved outside the cap body 531 and compresses the cap body 531 on the base 51. The first surrounding edge portion 542 surrounds the second surrounding edge portion 532, and the second surrounding edge portion 532 extends out of the first surrounding edge portion 542. Therefore, when the first surrounding edge portion 542 and the second surrounding edge portion 532 are pressed on the panel 40, the second surrounding edge portion 532 extends out of the first surrounding edge portion 542, so that the second surrounding edge portion 532 is preferentially abutted with the panel 40 and deformed. When the first surrounding edge portion 542 is abutted on 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 tightly expanded between the first surrounding edge portion 542 and the base 51, thereby increasing the engagement force between the compression cover 54 and the base 51, improving the bonding force of the waterproof cap 53 between the compression cover 54 and the base 51, and further facilitating the safety pull test of the waterproof cap 53. In addition, the deformed second surrounding edge portion 532 is tightly abutted on the panel 40, which can further improve the bonding force between the waterproof cap 53 and the panel 40, and is beneficial to improve the waterproof performance.

[0072] It should be noted that, in order to facilitate the cap body 531 to be more stably abutted on the base 51, the cap body 531 can comprise a covering portion 53a and a connecting portion 53b connected to the covering portion 53a in a circumferential direction, and the second surrounding edge portion 532 is connected to the connecting portion 53b. The compression portion 541 compresses the connecting portion 53b on the base 51.

[0073] Further, referring to Figure 13 The size of the second surrounding edge portion 532 extending out of the first surrounding edge portion 542 is h, and 4mm≤h≤8mm. Therefore, in order to prevent the waterproof cap 53 from contacting the switch element 52 on the base 51, the waterproof cap 53 should meet the safety pull requirement, for example, in the experiment, a pull force is applied to the waterproof cap 53 and lasts for 10s, and the pull force can meet 30N to determine whether the waterproof cap 53 is pulled out. If the size of the second surrounding edge portion 532 extending out of the first surrounding edge portion 542 is too short, the engagement force between the compression cover 54 and the base 51 will be too small, which will cause the pull test of the waterproof cap 53 to not meet the safety pull requirement. If the size is too long, the waterproof cap 53 and the compression cover 54 cannot be effectively installed on the panel 40.

[0074] Therefore, in this embodiment, the size of the second surrounding edge portion 532 extending out of the first surrounding edge portion 542 is controlled to be between 4mm and 8mm, for example, but not limited to, 4mm, 5mm, 6mm, 7mm, 8mm, etc. In this way, the waterproof cap 53 can meet the effective installation and fixation while also meeting the safety pull test requirement.

[0075] In some embodiments, referring to Figure 11 With Figure 13 , the panel 40 is provided with a sink 43, and the mounting hole 42 is arranged on the bottom wall of the sink 43. The gland 54 and one end of the waterproof cap 53 abut against the part of the bottom wall of the sink 43 located outside the periphery of the mounting hole 42, and the side of the gland 54 away from the waterproof cap 53 abuts against the side wall of the sink 43. Therefore, the sink 43 is arranged on the panel 40, so that the gland 54 and the waterproof cap 53 are fixed in the sink 43. At the same time, the gland 54 is stably fixed in the sink 43 in an interference fit manner, improving the stability of the installation of the switch component 50 on the panel 40.

[0076] In some embodiments, referring to Figure 14 The application provides an electric oil heater, which comprises: a heater body 200 and a front shell assembly 100 according to any one of the preceding embodiments. The cover 10 is arranged 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 electric oil heater described above adopts the front shell assembly 100 described above, and the cover body 20 is arranged at the opening 16 of the cover 10, so that the cooperation of the cover body 20 and the cover 10 effectively protects the front side of the heater body 200. Since the blocking rib 30 is arranged at one end of the cover body 20 away from the cover main body 11 along the second direction Y, and the blocking rib 30 protrudes along the second direction Y and away from the cover main body 11, 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 blocking rib 30 protruding along the second direction Y can shield the heater body 200, effectively preventing water from directly dripping or seeping between the heater body 200 and the cover body 20, thereby preventing water from flowing into the inside of the front shell assembly 100. Since the blocking rib 30 extends along the first direction X, the blocking rib 30 can effectively shield part of the heater body 200 along the first direction X, and also facilitates the water dripping on the blocking rib 30 to flow to both sides of the heater body 200 along the first direction X. In addition, the blocking rib 30 arranged on the cover body 20 also facilitates the strengthening of the structural strength of the cover body 20, the reduction of the deformation of the cover body 20, and the improvement of the gap between the cover body 20 and the heater body 200. The design of introducing the blocking rib 30 is conducive to reducing the risk of water entering the inside of the front shell assembly 100, thereby improving the safety of the electric oil heater.

[0078] It should be noted that the electric oil heater further comprises a heating assembly 300 and a stopper, and the heating assembly 300 is used for heating the inside of the heater body 200. Meanwhile, the electric oil heater can further comprise a rolling assembly 400 arranged at the bottom of the heater body 200 to enable the electric oil heater to move stably.

[0079] Further, referring toFigure 15 The fin body 200 includes a plurality of heat dissipation bodies 210 arranged in sequence along the second direction Y, and the heat dissipation body 210 includes a first heat dissipation body 211 at one end of the second direction Y. The cover 10 is arranged on one side of the first heat dissipation body 211, and the cover body 20 is arranged above the first heat dissipation body 211. The end of the blocking rib 30 away from the cover body 11 exceeds the top of the first heat dissipation body 211 in the second direction Y. Therefore, the end of the blocking rib 30 away from the cover body 11 exceeds the top of the first heat dissipation body 211 in the second direction Y, which provides shielding for the fin body 200, effectively prevents water from directly falling or seeping between the fin body 200 and the cover body 20, and further prevents water from flowing into the inside of the front shell assembly 100.

[0080] It should be noted that the first heat dissipation body 211 introduced in the embodiment has the same structure as the heat dissipation body 210, which is introduced as a concept to distinguish the heat dissipation body 210 assembled in the front shell assembly 100.

[0081] The technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.

[0082] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, some modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
