DETAILED DESCRIPTION

[0057] In the case of no conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other, and the detailed description in the specific embodiments should be understood as the explanation and illustration of the purpose of the present application, and should not be regarded as improper limitation on the present application.

[0058] It should be noted that in the embodiments of the present application, down refers to the direction in which the ground is located, and up is opposite to down. In the embodiments of the present application, the up, down, left, right, front and back directions or positional relationships are based on the directions or positional relationships shown in the drawings. It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0059] It should be noted that in the embodiments of the present application, multiple includes two and more than two.

[0060] Please refer to Figures 1 to 4 , the electric control box 1 is used to provide control functions for electrical equipment, for example, the electric control box 1 can control the electrical equipment to turn on or off or mode selection and the like. The electrical equipment includes but is not limited to the heat pump water heater 100. It can be understood that the electric control box 1 can also be used for electrical equipment other than the heat pump water heater 100, for example, a heat pump air conditioning device. The embodiments of the present application take the heat pump water heater 100 as an example for description.

[0061] Please refer to Figures 2 to 4 , the present application provides a handpiece assembly 20, the handpiece assembly 20 includes the electric control box 1 in any one of the embodiments of the present application.

[0062] The handpiece assembly 20 can be used for the heat pump water heater 100, and the handpiece assembly 20 can integrate at least part of the electrical components in the heat pump water heater 100.

[0063] Please refer to Figures 1 to 19 , the present application provides a heat pump water heater 100, the heat pump water heater 100 includes the handpiece assembly 20 in any one of the embodiments of the present application. That is, the electric control box 1 provided by the embodiments of the present application can be used for the heat pump water heater 100.

[0064] The heat pump water heater 100 can also be a variable frequency heat pump water heater, that is, the control mainboard can be provided with a frequency converter, for example, the compressor 25 can be a variable frequency compressor, and the frequency converter can adjust the frequency of the variable frequency compressor.

[0065] In the related art, the electric control box includes an upper cover and a lower cover. The upper cover and the lower cover are buckled to define a mounting cavity. An electric control mainboard is located in the mounting cavity and connected with the upper cover. A rotating shaft is mounted on the upper cover. The lower cover has an opening slot for accommodating the rotating shaft. The rotating shaft enters the opening slot through the opening of the opening slot to realize the rotating connection between the upper cover and the lower cover. Since the conductive wires need to be electrically connected with the devices outside the electric control box, that is, one end of the conductive wires needs to be fixed outside the electric control box, the terminals of the conductive wires need to be inserted into the electric control mainboard first, and then the upper cover can be assembled to the lower cover. During the assembly of the electric control box, the rotating shaft enters the opening slot through the opening of the opening slot. Since the included angle between the upper cover and the lower cover is greater than 90°, the rotating shaft is easily separated from the opening slot, causing the upper cover to fall. Therefore, the upper cover needs to be rotated to an included angle less than 90° with the lower cover, and a tool is used to support the upper cover. During the assembly of the conductive wires to the electric control mainboard, the upper cover needs to be manually held to avoid the upper cover rotating away from the lower cover to cause the included angle to be greater than 90°. This assembly method is inconvenient to operate, and the production efficiency is relatively low. The tool is needed to support the upper cover, increasing the production cost. The operator is also prone to misoperation, causing the upper cover to fall, damaging the electric control mainboard or other structural parts, and causing losses.

[0066] Please refer to Figure 3 The electric control box 1 includes a cover assembly 11, an electric control mainboard 13 and a box body assembly 12.

[0067] The electric control mainboard 13 is a key component of the electric control box 1. The electric control mainboard 13 provides control functions. The electric control mainboard 13 can be a circuit board provided with circuits and electrical elements.

[0068] The electric control mainboard 13 can be electrically connected with electrical components of an electric appliance through conductive wires to control the electrical components. The electrical components include, but are not limited to, at least one of a motor, a compressor 25, a throttling device, an electric control switch, a display panel and a sensor.

[0069] Please refer to Figures 3 to 8 The cover assembly 11 includes a cover main body 111 and a first plug-in piece 112. The electric control mainboard 13 is arranged on the cover main body 111. The box body assembly 12 includes a box body main body 121 and a second plug-in piece 122. The cover main body 111 has an open state of unfolding relative to the box body main body 121 and a buckled state of buckling the box body main body 121. When the cover main body 111 is in the open state, the first plug-in piece 112 is inserted into the second plug-in piece 122. When the cover main body 111 is in the buckled state, the first plug-in piece 112 and the second plug-in piece 122 are disengaged.

[0070] Please refer to Figure 6When the box cover body 111 is in the open state, for example, the included angle between the box cover body 111 and the box body 121 is greater than 0°, in other words, the box cover body 111 is in the standing posture, the box cover body 111 does not close the upward opening of the box body 121, and the internal structure of the box body 121 can be exposed.

[0071] When the box cover body 111 is in the open state, the electric control mainboard 13 remains in the standing posture with the box cover body 111, and the electric control mainboard 13 can face the operator to facilitate the operator to assemble the conductive wire to the electric control mainboard 13.

[0072] Please refer to Figure 5 and Figure 8 When the box cover body 111 is in the closed state, for example, the included angle between the box cover body 111 and the box body 121 can be equal to 0°, in other words, the box cover body 111 is in the prone posture, the box cover body 111 closes the upward opening of the box body 121, and the internal structure of the box body 121 cannot be exposed.

[0073] When the box cover body 111 is in the closed state, the electric control mainboard 13 remains in the prone posture with the box cover body 111, and the electric control mainboard 13 can face the box body 121, and the electric control mainboard 13 is contained in the placement cavity defined by the box cover body 111 and the box body 121.

[0074] The first plug-in part 112 and the second plug-in part 122 remain plugged, so that the box cover body 111 can remain in the open state. The first plug-in part 112 and the second plug-in part 122 are unplugged, so that the box cover body 111 can close the box body 121, and the box cover body 111 closes the upward opening of the box body 121.

[0075] As an example, during the assembly of the electric control box 1, that is, during the production process of the electric control box 1, the first plug-in part 112 can be inserted into the second plug-in part 122, the box cover body 111 can remain in the open state, and the box cover body 111 can be stably kept in the standing posture without falling. The operator does not need to hold the box cover body 111 with one hand, and can not need to additionally increase the tool to support the box cover body 111. The operator can assemble the conductive wire to the electric control mainboard 13 provided on the box cover body 111 with both hands, and the operation is simple.

[0076] The electric control box 1 is provided in the embodiment of the application. The first plug-in part 112 can be inserted into the second plug-in part 122. The box cover body 111 can be kept in an open state. The box cover body 111 can be stably kept in an upright posture without falling. An operator can not need to hold the box cover body 111 with one hand, and can not need to additionally increase a tool to support the box cover assembly 11. The operator can assemble the conductive wire to the electric control mainboard 13 arranged on the box cover body 111 with both hands. The operation is simple, the difficulty of wire assembly is reduced, the production efficiency is improved, and the risk of product damage caused by falling of the box cover body 111 is also reduced.

[0077] In some embodiments, referring to Figures 3 to 6 , the back surface 132 of the electric control mainboard 13 can face the box cover body 111, and the front surface 131 of the electric control mainboard 13 can be away from the box cover body 111. The electrical elements can be fixed on the front surface 131 of the electric control mainboard 13. Referring to Figures 3 to 4 , the front surface 131 of the electric control mainboard 13 can face downward when the box cover body 111 is in the buckling state, and the electrical elements are located in the placement cavity.

[0078] In this embodiment, the front surface 131 of the electric control mainboard 13 has an angle greater than 0° with the horizontal plane when the box cover body 111 is in the open state. Preferably, the angle between the front surface 131 of the electric control mainboard 13 and the horizontal plane can be not less than 60° and not greater than 120°. For example, the angle between the front surface 131 of the electric control mainboard 13 and the horizontal plane can be 90°. In this way, the front surface 131 of the electric control mainboard 13 can generally face the operator, so that the operator can easily check the installation position of the conductive wire on the electric control mainboard 13. The front surface 131 of the electric control mainboard 13 can face downward when the box cover body 111 is in the buckling state, and the electrical elements arranged on the front surface 131 are also located below the electric control mainboard 13.

[0079] The connection mode of the electric control mainboard 13 and the box cover body 111 is not limited. The electric control mainboard 13 and the box cover body 111 can be detachably connected or non-detachably connected. The detachable connection includes but is not limited to clamping and / or fastener connection and the like. The non-detachable connection includes but is not limited to bonding and / or welding and the like.

[0080] The fastener includes but is not limited to a screw or a bolt and the like.

[0081] The connection mode of the conductive wire and the electric control mainboard 13 is not limited. The conductive wire can be plugged into or clamped to the electric control mainboard 13 through a wire terminal or the like.

[0082] In some embodiments, referring to Figure 3 and Figure 5The electric control box 1 comprises a heat dissipation fin 15, one end of the heat dissipation fin 15 can be fixed on the front face 131 of the electric control main board 13, and the other end of the heat dissipation fin 15 can extend to the outside of the electric control box 1. For example, the other end of the heat dissipation fin 15 can extend to the lower side of the box body main part 121. The heat dissipation fin 15 can transfer the heat generated by the electric control main board 13 and the electrical elements to the outside environment of the electric control box 1, so as to reduce the temperature of the electric control main board 13 and the electrical elements, and achieve the purpose of heat dissipation and cooling.

[0083] The heat dissipation fin 15 can be made of a good thermal conductor material such as aluminum or copper.

[0084] In some embodiments, referring to Figure 3 and Figure 5 , the box body main part 121 is placed horizontally. That is, the surface with the largest area of the box body main part 121 is substantially parallel to the horizontal plane, and the thickness direction of the box body main part 121 is perpendicular to the horizontal direction.

[0085] In some embodiments, referring to Figures 3 to 19 , the second plug-in part 122 forms a slot 122a, the first plug-in part 112 is inserted into the slot 122a when the box cover main part 111 is in the open state (see Figure 7 ), and the first plug-in part 112 is out of the slot 122a when the box cover main part 111 is in the buckling state (see Figure 9 ).

[0086] The insertion of the first plug-in part 112 into the slot 122a makes the first plug-in part 112 and the second plug-in part 122 remain plugged.

[0087] The out of the slot 122a of the first plug-in part 112 makes the first plug-in part 112 and the second plug-in part 122 unplug.

[0088] When the box cover main part 111 needs to be placed vertically, the box cover main part 111 containing the electric control main board 13 can be lifted, and the first plug-in part 112 is inserted into the slot 122a. In this way, the first plug-in part 112 and the second plug-in part 122 remain plugged, and the box cover main part 111 can remain in the open state.

[0089] In this embodiment, when the first plug-in part 112 is inserted into the slot 122a, the wall surface of the slot 122a limits the first plug-in part 112, so that the box cover main part 111 can be stably kept in the open state. When the first plug-in part 112 is out of the slot 122a, the first plug-in part 112 and the second plug-in part 122 unplug, the wall surface of the slot 122a no longer limits the first plug-in part 112, and the box cover main part 111 can be buckled to the box body main part 121.

[0090] It is to be understood that the size of the portion of the first connector 112 inserted into the slot 122a can be smaller than the size of the slot 122a. For example, the width of the first connector 112 can be smaller than the width of the slot 122a, the thickness of the first connector 112 can be smaller than the thickness of the slot 122a, and the length of the first connector 112 can be equal to or greater than the depth of the slot 122a. Thus, the first connector 112 can be inserted into the slot 122a.

[0091] In some embodiments, referring to Figures 12 to 19 , the second connector 122 includes a surrounding plate 1221 extending along the outer circumferential surface of the box body 121 and defining the slot 122a.

[0092] The outer circumferential surface of the box body 121 refers to the surface of the box body 121 surrounding a straight line extending in the up-down direction.

[0093] In this embodiment, a portion of the outer circumferential surface of the box body 121 can be used as the wall surface of the slot 122a, thereby simplifying the structure of the second connector 122.

[0094] As an example, the second connector 122 can be a metal structure. The metal structure refers to a structure made of a metal material.

[0095] In some embodiments, referring to Figure 15 and Figure 19 , the at least one second connector 122 includes a bent edge 1222 connected to the lower end of the surrounding plate 1221 and bent toward the lower portion of the slot 122a.

[0096] The at least one second connector 122 including the bent edge 1222 means that one second connector 122 can have the bent edge 1222, while the at least one second connector 122 does not have the bent edge 1222. Alternatively, all second connectors 122 can have the bent edge 1222.

[0097] In this embodiment, the bent edge 1222 can be used to support the first connector 112 upward when the first connector 112 is inserted into the slot 122a.

[0098] In some embodiments, referring to Figures 12 to 17 , the electric control box 1 includes a support plate 14 for supporting the box body 121, and a portion of the support plate 14 extends to the lower portion of the at least one slot 122a.

[0099] The portion of the support plate 14 extending to the lower portion of the at least one slot 122a means that one slot 122a can have a portion of the structure of the support plate 14 at the lower portion, while the at least one slot 122a does not have the structure of the support plate 14 at the lower portion. Alternatively, all slots 122a can have a portion of the structure of the support plate 14 at the lower portion.

[0100] In this embodiment, when the first plug-in part 112 is inserted into the slot 122a, the part of the structure of the supporting plate 14 below the slot 122a can be used to support the first plug-in part 112 upward.

[0101] In some embodiments, referring to Figures 12 to 19 , the number of the second plug-in parts 122 is two, one of which includes the folded edge 1222, and the other of which has the part of the structure of the supporting plate 14 below the slot 122a.

[0102] In some embodiments, referring to Figure 7 , the second plug-in part 122 forms a boss 1223, which is located on the side of the slot 122a away from the box body 121, and the box cover body 111 abuts against the boss 1223 when the box cover body 111 is in the open state. Specifically, the boss 1223 extends upward from the second plug-in part 122.

[0103] When the box cover body 111 is in the open state and the first plug-in part 112 is inserted into the slot 122a, the box cover body 111 abuts against the boss 1223.

[0104] In this embodiment, when the box cover body 111 is in the open state and the box cover body 111 abuts against the boss 1223, the boss 1223 can provide support for the box cover body 111, not only lengthening the support arm to reduce the shaking of the box cover body 111, but also reducing the risk of deformation of the box cover body 111.

[0105] The first plug-in part 112 can be an integrally formed structure, for example, the first plug-in part 112 can be a sheet metal structure formed by sheet metal processing. Alternatively, the first plug-in part 112 can be a plastic structure integrally formed by injection molding.

[0106] The second plug-in part 122 can be an integrally formed structure, for example, the second plug-in part 122 can be a sheet metal structure formed by sheet metal processing. Alternatively, the second plug-in part 122 can be a plastic structure integrally formed by injection molding.

[0107] In some embodiments, referring to Figures 12 to 19 , the first plug-in part 112 and the second plug-in part 122 are both metal structures. Metal structures have good structural strength.

[0108] In order to facilitate processing and manufacturing, the first plug-in part 112 can adopt a sheet metal structure. The second plug-in part 122 can adopt a sheet metal structure.

[0109] Sheet metal structure refers to a structure formed by cold working such as stamping, shearing or bending of a metal plate. That is, the second plug-in part 122 is a structure formed by cold working such as stamping, shearing or bending of a metal plate.

[0110] In some embodiments, referring to Figures 1 to 11 The first connector 112 and the second connector 122 are both plastic structures. Plastic structures are lighter in weight and relatively lower in cost.

[0111] To improve the fireproof effect, at least one of the first connector 112 and the second connector 122 can be made of flame-retardant plastic.

The first connector 112 is connected to both the first side wall 11111 and the second side wall 11112, and when the first connector 112 is connected to the second connector 122, the force of the operator installing the electric control main board 13 and the conductive wire is transmitted to the connection between the first connector 112 and the first side wall 11111 and the second side wall 11112, which can improve the stress capacity, effectively enhance the connection strength of the first connector 112, and reduce the risk of the first connector 112 falling off.

[0116] In some embodiments, the surrounding plate 1221 includes a groove-shaped plate and two supporting plates, the groove-shaped plate and the box body 121 together define a slot 122a, and the two supporting plates are connected to two ends of the groove-shaped plate, one of which is connected to the first side wall 11111, and the other of which extends from the first side wall 11111 to the second side wall 11112. That is, the other supporting plate is connected to the first side wall 11111 and the second side wall 11112.

[0117] In some embodiments, referring to Figures 13 to 16The number of the first plug-in members 112 is two.

The two first plug-in members 112 are respectively connected to the same first side wall 11111 and the two second side walls 11112.

[0118] In this embodiment, the two first plug-in members 112 can be respectively arranged at two ends of the metal box cover 1111. The two first plug-in members 112 are more balanced in force, and the box cover body 111 is more stably kept in the open state.

[0119] For example, in some embodiments, the first side wall 11111 and the second side wall 11112 are welded with the first plug-in member 112. In some embodiments, the first side wall 11111 and the second side wall 11112 are connected with the first plug-in member 112 through fasteners.

[0120] In some embodiments, the number of the first plug-in members 112 is one. The metal box cover 1111 comprises two second side walls 11112, which are respectively connected to two ends of the first side wall 11111 and extend in the same direction. The first plug-in member 112 can be connected to the first side wall 11111 and the two second side walls 11112.

[0121] It can be understood that the number of the first plug-in members 112 can also be more than two.

[0122] In some embodiments, referring to Figures 13 to 16 The box body 121 comprises a metal box body 1211. The metal box body 1211 comprises a third side wall 12111 and a fourth side wall 12112. The fourth side wall 12112 is connected to the third side wall 12111 and extends away from the third side wall 12111. The second plug-in member 122 is connected to both the third side wall 12111 and the fourth side wall 12112.

[0123] The metal box body 1211 is a metal structure made of metal material.

[0124] The third side wall 12111 and the fourth side wall 12112 are connected and intersected. The third side wall 12111 and the fourth side wall 12112 can be two side walls of a circumferential wall of the metal box body 1211.

[0125] In this embodiment, the metal box body 1211 can improve the fireproof performance of the box body 121. The second connector 122 is connected with both the third side wall 12111 and the fourth side wall 12112. When the first connector 112 is connected with the second connector 122, the force applied by the operator to install the electric control main board 13 and the conductive wire is transmitted to the connection between the second connector 122 and the third side wall 12111 and the fourth side wall 12112, which can improve the stress capacity, effectively enhance the connection strength of the second connector 122, and reduce the risk of falling of the second connector 122.

[0126] In some embodiments, referring to Figures 13 to 16 , the number of the second connectors 122 is two, the metal box body 1211 includes two fourth side walls 12112, the two fourth side walls 12112 are respectively connected with two ends of the third side wall 12111, the two fourth side walls 12112 extend in the same direction, and the two second connectors 122 are respectively connected with the same third side wall 12111 and the two fourth side walls 12112.

[0127] In this embodiment, the two second connectors 122 can be respectively arranged at two ends of the metal box body 1211, and the two second connectors 122 are more balanced in stress, thereby more stably maintaining the box cover body 111 in the open state.

[0128] For example, in some embodiments, the third side wall 12111 and the fourth side wall 12112 are welded with the second connector 122. In some embodiments, the third side wall 12111 and the fourth side wall 12112 are connected with the second connector 122 by fasteners.

[0129] In some embodiments, the number of the second connectors 122 is one, the metal box body 1211 includes two fourth side walls 12112, the two fourth side walls 12112 are respectively connected with two ends of the third side wall 12111, the two fourth side walls 12112 extend in the same direction, and the second connector 122 can be connected with the third side wall 12111 and the two fourth side walls 12112.

[0130] It can be understood that the number of the second connectors 122 can also be more than two.

[0131] In some embodiments, referring to Figure 9 , the first connector 112 is formed with a first hole 112a and a second hole 112b, the opening direction of the first hole 112a is opposite to the opening direction of the second hole 112b, and the first hole 112a and the second hole 112b are arranged in a staggered manner. Specifically, the first hole 112a and the second hole 112b are both blind holes.

[0132] The first hole 112a and the second hole 112b are misaligned, which means that the projections of the first hole 112a and the second hole 112b in the depth direction do not overlap, for example, when the box cover body 111 is in the buckled state, the horizontal plane is the projection plane, and the projection of the first hole 112a and the projection of the second hole 112b do not overlap.

[0133] In this embodiment, the first hole 112a and the second hole 112b can improve the structural strength of the first plug-in part 112, and the first plug-in part 112 can more stably support the box cover body 111. Even if the operator does not hold the box cover body 111, the box cover body 111 and the electric control mainboard 13 can maintain an upright posture, reducing the shaking of the box cover body 111 and the electric control mainboard 13.

[0134] In some embodiments, the first plug-in part 112 can be a metal structure, and the first hole 112a and the second hole 112b can be formed by stamping or other processes.

[0135] In some embodiments, the first plug-in part 112 can be a plastic structure, and the first hole 112a and the second hole 112b can be formed by injection molding or other processes.

[0136] In some embodiments, please refer to Figure 10 and Figure 11 The box cover body 111 includes a metal box cover 1111 and a plastic box cover 1112, the metal box cover 1111 covers the outside of the plastic box cover 1112, and the metal box cover 1111 includes an extension part 11113 covering at least part of the surface of the first plug-in part 112.

[0137] The plastic box cover 1112 can improve the insulation performance of the box cover body 111, and the metal box cover 1111 can improve the fireproof performance of the box cover body 111.

[0138] The metal box cover 1111 covers the outside of the plastic box cover 1112 means that the metal box cover 1111 covers at least part of the outer surface of the plastic box cover 1112, for example, the metal box cover 1111 covers the entire outer surface of the plastic box cover 1112 or covers part of the outer surface of the plastic box cover 1112.

[0139] As an example, the shape of the metal box cover 1111 can be adapted to the shape of the plastic box cover 1112, and the metal box cover 1111 can be nested with the plastic box cover 1112 to form a double-layer structure.

[0140] In this embodiment, the extension 11113 covers at least part of the surface of the first connector 112. The extension 11113 can improve the structural strength of the first connector 112. The extension 11113 and the first connector 112 can jointly provide a supporting force. The extension 11113 and the first connector 112 can more stably support the box cover body 111. Even if the worker does not hold the box cover body 111, the box cover body 111 and the electric control mainboard 13 can maintain an upright posture, and the shaking of the box cover body 111 and the electric control mainboard 13 is reduced.

[0141] In some embodiments, the extension 11113 can be a single-layer sheet structure. In other words, the extension 11113 can be a single-layer structure in which the metal box cover 1111 extends to the first connector 112.

[0142] In some embodiments, referring to Figure 11 , the extension 11113 is folded into a multi-layer structure. In other words, the extension 11113 can be a multi-layer structure in which the metal sheet of the metal box cover 1111 extends to the first connector 112 is repeatedly folded. The extension 11113 has better structural strength.

[0143] In some embodiments, referring to Figure 7 , the box body 121 includes a metal box body 1211 and a plastic box body 1212. The metal box body 1211 covers the outside of the plastic box body 1212. The box body 121 includes a force-bearing rib 1213 arranged below the second connector 122. The metal box body 1211 includes a folded edge 12113 located on the side of the force-bearing rib 1213 close to the plastic box body 1212. The folded edge 12113 is used to abut against the force-bearing rib 1213.

[0144] The plastic box body 1212 can improve the insulation performance of the box body 121, and the metal box body 1211 can improve the fireproof performance of the box body 121.

[0145] The metal box body 1211 covering the outside of the plastic box body 1212 means that the metal box body 1211 covers at least part of the outer surface of the plastic box body 1212, for example, the metal box body 1211 covers the entire outer surface of the plastic box body 1212 or covers part of the outer surface of the plastic box body 1212.

[0146] As an example, the shape of the metal box body 1211 can be adapted to the shape of the plastic box body 1212. The metal box body 1211 and the plastic box body 1212 are nested to form a double-layer structure.

[0147] In this embodiment, the overlapping edge 12113 and the force bearing rib 1213 are arranged in opposite positions. When the first connector 112 is connected to the second connector 122, for example, when the first connector 112 is inserted into the slot 122a, the force generated by the assembly of the conductive wire to the electric control mainboard 13 causes the force bearing rib 1213 to move towards the overlapping edge 12113. If the force bearing rib 1213 abuts against the overlapping edge 12113, it can prevent the force bearing rib 1213 from directly abutting against the plastic box body 1212 to a certain extent, thereby reducing the risk of damage to the plastic box body 1212 and the metal box body 1211.

[0148] In some embodiments, the overlapping edge 12113 can have a single-layer sheet structure. In other words, the overlapping edge 12113 can be a single-layer structure formed by folding a metal sheet extending from the metal box body 1211 once.

[0149] In some embodiments, the overlapping edge 12113 can be folded into a multi-layer structure. In other words, the overlapping edge 12113 can be formed by repeatedly folding a metal sheet extending from the metal box body 1211 into multiple layers.

[0150] In some embodiments, the second connector 122 and the force bearing rib 1213 can be plastic structures. For example, the second connector 122, the force bearing rib 1213, and the plastic box body 1212 can be an integrally formed structure.

[0151] In some embodiments, referring to Figure 7 , the plastic box body 1212 is formed with a reinforcing rib 12121, and the reinforcing rib 12121 and the overlapping edge 12113 are located on opposite sides of the same side wall of the plastic box body 1212.

[0152] In this embodiment, the reinforcing rib 12121 can be located inside the plastic box body 1212. The reinforcing rib 12121 can improve the structural strength of the portion of the plastic box body 1212 corresponding to the overlapping edge 12113, thereby reducing the risk of local damage to the plastic box body 1212 caused by the transmission of force to the plastic box body 1212 when the force bearing rib 1213 abuts against the overlapping edge 12113.

[0153] As an example, the first connector 112 is a plastic structure. In the case where the box cover body 111 includes a plastic box cover 1112 and a metal box cover 1111, the metal box cover 1111 can form a first avoiding opening, and the first connector 112 and the plastic box cover 1112 can be an integrally formed structure. The first avoiding opening is used to avoid the first connector 112.

[0154] As an example, the second connector 122 is a plastic structure, in the case where the box body 121 includes a plastic box body 1212 and a metal box body 1211, the metal box body 1211 can form a second avoiding opening, and the second connector 122 and the plastic box body 1212 can be an integral structure, and the second avoiding opening is used to avoid the second connector 122.

[0156] In this embodiment, the box cover body 111 is in a buckled state, the connecting piece is arranged through the through hole 112c and the fastening hole 122b, the first connector 112 and the second connector 122 can be connected through the connecting piece, so that the connection stability between the box cover body 111 and the box body 121 can be enhanced.

[0157] The connecting piece includes but is not limited to a screw or a bolt, etc.

[0158] As an example, the connecting piece can be a screw, the fastening hole 122b can form an internal thread, and the connecting piece can pass through the through hole 112c and be screwed with the fastening hole 122b.

[0159] As an example, the connecting piece can also include a bolt and a nut, the bolt can pass through the through hole 112c and the fastening hole 122b and be screwed with the nut.

[0160] In some embodiments, the fastening hole 122b can be arranged apart from the slot 122a along the first direction, the boss 1223 is located on the side of the slot 122a away from the box body 121, and in the case where the box cover body 111 is in a buckled state, the first connector 112 and the slot 122a are at least partially misaligned along the first direction. In this way, the through hole 112c and the fastening hole 122b can be aligned, and the first connector 112 and the boss 1223 do not interfere.

[0161] In some embodiments, referring to Figures 3 to 9 , the number of the first connectors 112 is multiple, and the multiple first connectors 112 are all connected with the same second connector 122.

[0162] In this embodiment, the first connector 112 is multiple, and the second connector 122 can be one, and the multiple first connectors 112 are all connected with the same second connector 122, which can take into account the manufacturing requirements and assembly requirements.

[0163] In some embodiments, referring to Figures 3 to 8The second plug-in piece 122 is located at a position of the box body main part 121 close to the middle along the first direction, and the two first plug-in pieces 112 are arranged at intervals along the first direction on the box cover main part 111. The first direction is perpendicular to the horizontal direction. In this way, the size of the second plug-in piece 122 can be relatively small, which is easy to manufacture.

[0164] In some embodiments, referring to Figures 12 to 19 The number of the first plug-in pieces 112 and the second plug-in pieces 122 is multiple, and each first plug-in piece 112 corresponds to a second plug-in piece 122.

[0165] In this embodiment, each first plug-in piece 112 corresponds to a second plug-in piece 122, and the structure of a single first plug-in piece 112 and a single second plug-in piece 122 can be simple and easy to manufacture, and the first plug-in piece 112 and the second plug-in piece 122 can be arranged more flexibly.

[0166] In some embodiments, referring to Figures 12 to 19 The two second plug-in pieces 122 are arranged at the two ends of the box body main part 121 along the first direction respectively, and each first plug-in piece 112 corresponds to a second plug-in piece 122. In this way, the stress of the two second plug-in pieces 122 is more balanced.

[0167] In some embodiments, referring to Figures 3 to 5 The handpiece assembly 20 includes the air guide shell 21, the electric control box 1 is connected with the air guide shell 21, and part of the box cover main part 111 is supported above the air guide shell 21 in the open state.

[0168] The electric control box 1 is connected with the air guide shell 21, and the air guide shell 21 can provide support force for the electric control box 1. For example, the supporting plate 14 can be fixed to the upper end of the air guide shell 21.

[0169] In this embodiment, in the production line production process, the box body main part 121 can be assembled to the air guide shell 21 first, the first plug-in piece 112 and the second plug-in piece 122 are plugged in, and then the electric control box 1 and the conductive wire are assembled. Part of the box cover main part 111 is supported above the air guide shell 21, which can further support the box cover main part 111 by using the air guide shell 21, thereby reducing the stress between the first plug-in piece 112 and the second plug-in piece 122.

[0170] As an example, referring to Figures 3 to 5 The first plug-in piece 112 can be located at a position of the box cover main part 111 close to the middle along the first direction. In this way, when the box cover main part 111 is in the open state, the first plug-in piece 112 does not interfere with the part of the box cover main part 111 supported above the air guide shell 21.

[0171] In some embodiments, the heat sink 15 can be located on the side of the control mainboard close to the air guide shell 21, and when the box cover body 111 is in the open state, the part of the box cover body 111 where the heat sink 15 is located is supported above the air guide shell 21. The mass of the heat sink 15 is relatively large, and the side of the box cover assembly 11 close to the heat sink 15 is heavy, and when the box cover body 111 is in the open state, the part of the box cover body 111 where the heat sink 15 is located is supported above the air guide shell 21, thereby reducing the strength requirement of the first plug-in part 112 and the second plug-in part 122.

[0172] In some embodiments, referring to Figures 3 to 5 , the head assembly 20 includes a fan wheel and a heat exchanger 22, and the fan wheel and the box body 121 are located on opposite sides of the heat exchanger 22.

[0173] The fan wheel is used to drive the airflow to flow.
