[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0040] The first aspect of the present application provides a motor assembly 2000, combined with Figures 1 to 5 As shown, the motor assembly 2000 includes a core component 2200 and a terminal block 2400 . The core component 2200 includes a core 2210 and a core support 2220 . The core 2210 is disposed on the core support 2220 , and the terminal block 2400 is connected to the core support 2220 .

[0041] The core bracket 2220 provides a connection structure for the installation of the terminal block 2400. When assembling the motor assembly 2000, the terminal block 2400 and the core component 2200 can be assembled together first, or the core component 2200 and the terminal block 2400 can be assembled in sequence. The terminal block 2400 is supported by the core component 2200. Based on the fixed design of the core component 2200, the terminal block 2400 can be fixed.

[0042] The motor assembly 2000 will be described below in conjunction with the water pump 100. Specifically, the structure of the water pump 100 is as follows: the water pump 100 includes a pump body 1000 and a motor assembly 2000 that are connected to each other. The pump body 1000 includes a pump cover 1100, a pump housing 1200, a primary impeller 1410, and a secondary impeller 1420. The pump cover 1100 is connected to one side of the pump housing 1200, a primary cavity 1310 is formed between the pump cover 1100 and the pump housing 1200, and the primary impeller 1410 is rotatably disposed in the primary cavity 1310. The motor assembly 2000 is connected to the other side of the pump housing 1200, a secondary cavity 1320 is formed between the motor assembly 2000 and the pump housing 1200, and the secondary impeller 1420 is rotatably disposed in the secondary cavity 1320.

[0043] The motor assembly 2000 includes a rotor component 2300, a core component 2200, a shielding sleeve 2100 and a terminal block 2400. The rotor component 2300 and the core component 2200 are respectively installed on the shielding sleeve 2100. The shielding sleeve 2100 is generally made of insulating material. The core component 2200 is fixed relative to the shielding sleeve 2100, and the rotor component 2300 is rotatable relative to the shielding sleeve 2100. When the core component 2200 is energized, it can drive the rotor component 2300 to rotate. The connection between the motor assembly 2000 and the pump body 1000 is specifically achieved through the connection between the shielding sleeve 2100 of the motor assembly 2000 and the pump casing 1200 of the pump body 1000. There are various ways to connect the shielding sleeve 2100 and the pump casing 1200. For example, bolt holes are respectively provided on the periphery of the pump casing 1200 and the periphery of the shielding sleeve 2100, and the connection is achieved by passing bolts through the bolt holes. Furthermore, the pump cover 1100, the pump casing 1200, the shielding sleeve 2100 and the base 3000 described below can be respectively provided with bolt holes, and the various components can be fastened together by passing bolts through the bolt holes.

[0044] The rotor component 2300 can cooperate with the first-stage impeller 1410 and the second-stage impeller 1420, so as to drive the first-stage impeller 1410 and the second-stage impeller 1420 to rotate. The cooperation between the rotor component 2300 and the first-stage impeller 1410 and the second-stage impeller 1420 can be referred to the relevant technology and will not be described in detail here. The pump cover 1100 is provided with a water inlet interface 1110, which is communicated with the primary cavity 1310. The pump housing 1200 is provided with a water outlet interface 1120, which is communicated with the secondary cavity 1320. The core component 2200 of the motor assembly 2000 is energized to drive the rotor component 2300 to rotate, and the rotor component 2300 drives the primary impeller 1410 and the secondary impeller 1420 to rotate. Water enters the primary cavity 1310 from the water inlet interface 1110, enters the secondary cavity 1320 after being pressurized by the primary impeller 1410, and is discharged from the water outlet interface 1120 after being pressurized by the secondary impeller 1420. The water head is greatly provided through the action of the primary impeller 1410 and the secondary impeller 1420.

[0045] The core support 2220 includes an iron core 2210, an iron core support 2220 and a coil winding (not shown in the figure), the iron core 2210 is arranged on the iron core support 2220, and the coil winding is wound on the iron core support 2220. Generally speaking, the coil winding is not directly wound on the iron core 2210, but through the arrangement of the iron core support 2220, the coil winding is directly wound on the iron core support 2220 and thus indirectly wound on the iron core 2210, so as to prevent the iron core 2210 from damaging the insulation of the coil winding.

[0046] For example, Figure 6 and Figure 7 The core bracket 2220 shown includes a first bracket 2221 and a second bracket 2222. The first bracket 2221 is contoured to one axial end of the core 2210, and the second bracket 2222 is contoured to the other axial end of the core 2210. The so-called contouring means that the shapes are similar. In this way, the first bracket 2221 can be sleeved on one axial end of the core 2210, and the second bracket 2222 can be sleeved on the other axial end of the core 2210, thereby wrapping the core 2210. Of course, the core bracket 2220 can also realize the integral injection molding wrapping of the core 2210 as a whole, and then the coil winding is wound on the core bracket 2220 to realize the winding of the core 2210.

[0047] In order to realize power supply to the core component 2200, that is, to realize power supply to the coil winding, a terminal block 2400 is provided, the coil winding is electrically connected to the terminal block 2400, and the terminal block 2400 is electrically connected to an external power supply through a power line. In the related art, the terminal block 2400 is fixed only by the part of the coil winding connected to the terminal block 2400 and the aforementioned power line for restraint and fixation, but this method has a relatively poor fixing effect on the terminal block 2400. For this reason, in this embodiment, the terminal block 2400 and the core bracket 2220 are connected to achieve fixation.

[0048] The core component 2200 is fixed in the motor assembly 2000, that is, the core support 2220 is fixed. After the terminal block 2400 and the core support 2220 are connected, the core support 2220 is also fixed. The core support 2220 is fully utilized as a structural component. There is no need to design a structure connected to the terminal block 2400 on other components, thereby avoiding affecting the assembly of the core component 2200 and other components.

[0049] For example, when assembling the motor assembly 2000, the core component 2200 can be first installed on the shielding sleeve 2100 and then the terminal block 2400 can be installed on the core support 2220, or the core component 2200 and the terminal block 2400 can be first assembled with each other and then installed on the shielding sleeve 2100, and there is no need to set a structure for fixing the terminal block 2400 on the shielding sleeve 2100. Since the core component 2200 needs to be installed on the shielding sleeve 2100, if a structure for fixing the terminal block 2400 is set on the shielding sleeve 2100, then the structure is easy to interfere with the installation of the core component 2200, and in this embodiment, this is effectively avoided by connecting the terminal block 2400 to the core support 2220. The core support 2220 supports the terminal block 2400, avoids the position of the terminal block 2400 from changing arbitrarily, is conducive to the realization of the assembly process of the motor assembly 2000, and can prevent the terminal block 2400 from moving when it is vibrated and causing the failure of the electrical connection.

[0050] Combination Figures 6 to 9 As shown, in some embodiments of the present application, the core bracket 2220 is provided with a positioning column 2241 and a claw 2242, and the terminal block 2400 is provided with a positioning hole 2411 and a stop position 2412, the positioning hole 2411 is used to correspond with the positioning column 2241, and the stop position 2412 is used to correspond with the claw 2242, so that quick and stable assembly can be achieved when the terminal block 2400 is installed on the core bracket 2220.

[0051] Specifically, the cooperation between the positioning hole 2411 and the positioning column 2241 plays a role of preliminary positioning constraint, and the cooperation between the stop position 2412 and the claw 2242 plays a role of further locking. In the process of connecting the terminal block 2400 to the core bracket 2220, the positioning hole 2411 is aligned with the positioning column 2241, so that the positioning column 2241 is inserted into the positioning hole 2411. At this time, the position of the terminal block 2400 relative to the core bracket 2220 is initially constrained and fixed to achieve rapid position cooperation. The terminal block 2400 is then controlled to move relative to the core bracket 2220 until the claw 2242 hooks the stop position 2412, thereby achieving locking between the terminal block 2400 and the core bracket 2220. The terminal block 2400 is not easy to separate from the core 2200. It can be seen that the terminal block 2400 does not need to be connected to the core bracket 2220 with the help of external tools, which is convenient and quick.

[0052] Furthermore, for better fixing effect, in some embodiments of the present application, the positioning column 2241 is used to be inserted into the positioning hole 2411 on one side of the terminal block 2400, and the claw 2242 is used to be hooked to the stop position 2412 on the other side of the terminal block 2400.

[0053] Specifically, see Figure 6 In the orientation shown, the wiring board 2400 is located above the core component 2200, and the wiring board 2400 is installed on the core bracket 2220 from top to bottom. When the wiring board 2400 moves from top to bottom, the positioning hole 2411 is aligned with the positioning column 2241. As the wiring board 2400 moves to the limit position, the positioning column 2241 is inserted into the positioning hole 2411 (that is, the positioning column 2241 is inserted into the positioning hole 2411 from the lower side of the wiring board 2400), and the wiring board 2400 is restricted in the radial direction of the positioning column 2241. At the same time, the claw 2242 is hooked to the stop position 2412 on the upper side of the wiring board 2400, so that the wiring board 2400 cannot move upward to make the positioning hole 2411 separate from the positioning column 2241. Through such cooperation, the wiring board 2400 is constrained in three-dimensional space, thereby achieving effective fixation of the wiring board 2400.

[0054] It is understandable that in order to realize the hooking of the claw 2242 on the stop position 2412, the claw 2242 needs to be configured to be elastically deformable. Figure 6 The orientation shown is for reference. When the terminal block 2400 is installed from top to bottom to the core bracket 2220, the terminal block 2400 touches the claw 2242. At this time, the claw 2242 undergoes elastic deformation to prevent the terminal block 2400 from moving. When the terminal block 2400 is installed from top to bottom to the extreme position, the claw 2242 is reset and hooked on the stop position 2412.

[0055] Combination Figure 6and Figure 8 As shown, in some embodiments of the present application, the stopper 2412 constitutes a notch structure located at the edge of the wiring board 2400. It is understandable that the stopper 2412 has various forms, for example, the stopper 2412 is a clamping hole structure, the clamping hole structure includes a clamping hole and a clamping hole edge surrounding the clamping hole, when the wiring board 2400 is connected to the core bracket 2220, the clamping claw 2242 needs to be aligned with the clamping hole and inserted into the clamping hole and hooked on the clamping hole edge. In the present embodiment, the stop position 2412 is a notch structure, which includes a notch 24121 arranged on the edge of the terminal block 2400 and a notch edge 24122 corresponding to the notch 24121. It can be understood that the so-called notch 24121 is open. Since the positioning is achieved by plugging the positioning hole 2411 with the positioning column 2241, the present embodiment uses the notch structure, which is a card hole structure relative to the stop position 2412, to effectively reduce the difficulty of aligning the claw 2242 with the notch structure. The claw 2242 is inserted into the notch 24121 and hooked onto the notch edge 24122.

[0056] It is precisely because the stop position 2412 is a notch structure that when the claw 2242 hooks the stop position 2412, at least a portion of the claw 2242 can be embedded in the terminal block 2400 along the plane of the terminal block 2400, thereby reducing the space occupied and limiting the claw 2242 in the direction of the plane of the terminal block 2400 (i.e., the radial direction of the positioning column 2241), further improving the fixing effect of the terminal block 2400.

[0057] Combination Figure 8 As shown, the terminal block 2400 is also provided with a slot 2420, which is arranged at the edge of the terminal block 2400, and the slot 2420 is used for the power line clamping. The coil winding needs to be electrically connected to the terminal block 2400, and the terminal block 2400 is electrically connected to a power line connected to an external power source. In order to facilitate the electrical connection between the coil winding and the terminal block 2400, and the electrical connection between the power line and the terminal block 2400, the part of the coil winding connected to the terminal block 2400 has a redundant length, and the part of the power line connected to the terminal block 2400 has a redundant length. In order to avoid the part of the coil winding connected to the terminal block 2400 and the part of the power line connected to the terminal block 2400 from being loose, the corresponding part of the coil winding and the corresponding part of the power line (collectively referred to as the wire) can be inserted into the slot 2420 to achieve position limiting, so as to avoid messy wiring. Of course, other wires in the motor assembly 2000 can also be inserted into the slot 2420 to achieve position limiting, so as to optimize the arrangement of the wires.

[0058] Furthermore, the slot 2420 is connected to the notch structure. As mentioned above, the notch structure includes a notch 24121 and a notch edge 24122. The slot 2420 is connected to the notch structure, that is, the slot 2420 is connected to the notch 24121. Since the slot 2420 is connected to the notch structure, the notch 24121 and the slot 2420 can be processed synchronously on the edge of the wiring board 2400. Synchronization means that after the processing of the notch 24121 is completed, the processing tool can then enter the processing program for the slot 2420 without having to leave the wiring board 2400 and then find the corresponding position of the wiring board 2400 for processing. It is more consistent. If the slot 2420 and the notch 24121 are arranged at intervals, then after the processing tool processes the notch 24121, the processing tool needs to first exit the wiring board 2400 and then move to a suitable position to process the slot 2420. It can be understood that the notch structure can be formed after the notch 24121 is processed.

[0059] Combination Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the claw 2242 and the positioning column 2241 are defined as the first connecting component 2240, the stop position 2412 and the positioning hole 2411 are defined as the second connecting component 2410, the number of the first connecting components 2240 is multiple (multiple means two or more, the same below), the number of the second connecting components 2410 is also multiple, and the second connecting components 2410 correspond one-to-one to the first connecting components 2240.

[0060] Specifically, the terminal block 2400 has an appropriate size. For this reason, in the present embodiment, the number of the first connecting components 2240 and the number of the second connecting components 2410 are designed to be multiple, and the multiple first connecting components 2240 are distributed at intervals, and the multiple second connecting components 2410 are distributed at intervals. In this way, the terminal block 2400 is constrained in a larger range, thereby improving the fixing effect of the terminal block 2400.

[0061] Furthermore, the multiple first connecting components 2240 are designed to be non-collinearly arranged. Since the first connecting components 2240 correspond one-to-one to the second connecting components 2410, the multiple second connecting components 2410 are also correspondingly non-collinearly arranged. The non-collinearity here can be based on the connection line of the positioning columns 2241 of the multiple first connecting components 2240. Through the non-collinear arrangement of the multiple first connecting components 2240, the constraints on the terminal block 2400 are achieved in multiple directions, further improving the fixing effect of the terminal block 2400.

[0062] For example, the plurality of first connection components 2240 are designed to be arranged in an arc shape along the circumference of the motor component 2000, and the circumference of the motor component 2000 refers to the direction around the rotation axis of the water pump 100 (the rotation axis of the water pump 100 is the rotation axis of the rotor component 2300). It can be understood that the core component 2200 is in a ring shape around the rotation axis of the water pump 100, and the plurality of first connection components 2240 are designed to be arranged in an arc shape, so that the distribution of the plurality of first connection components 2240 fully utilizes the space occupied by the core component 2200.

[0063] Combination Fig. 9 As shown, in some embodiments of the present application, the core support 2220 is provided with a first limiting assembly 2230, and the limiting assembly 2230 includes a first stopper 2231 and a second stopper 2232, both of which are convexly arranged along the axial direction of the motor assembly (the axial direction of the motor assembly is the extension direction of the rotation axis of the water pump 100), and the first stopper 2231 is correspondingly arranged on the inner side of the core support 2220, and the second stopper 2232 is arranged on the outer side of the core support 2220, the inner side of the core support 2220 is the side close to the rotation axis of the water pump 100, and the outer side is the side away from the rotation axis of the water pump 100. When the coil winding is wound between the inner side and the outer side of the core support 2220, this part of the coil winding can be located between the first stopper 2231 and the second stopper 2232, and the first stopper 2231 and the second stopper 2232 realize the limiting of the coil winding.

[0064] Furthermore, combined with Fig. 9 As shown, the first connecting component 2240 is arranged on the first stop block 2231 or the second stop block 2232, that is, the positioning column 2241 and the claw 2242 are simultaneously arranged on the first stop block 2231 or the second stop block 2232, so that the positioning column 2241 and the claw 2242 can be relatively close to each other, and the positioning column 2241 and the claw 2242 are arranged close to each other, and the positioning column 2241 and the claw 2242 cooperate with each other to form an effective constraint on the terminal block 2400 in a smaller range (three-dimensional space constraint), and then a large range of constraints can be formed on the terminal block 2400 in a larger range through multiple first connecting components 2240. It can be understood that when multiple first connecting components 2240 are included, the first connecting components 2240 can be respectively arranged on multiple second blocks 2232.

[0065] For example, the positioning column 2241 and the claw 2242 are arranged on the second stopper 2232. When the terminal block 2400 is connected to the core support 2220, the terminal block 2400 is controlled to move toward the core support 2220 until the limit, the positioning column 2241 is inserted into the positioning hole 2411, the terminal block 2400 abuts against the second stopper 2232, and the claw 2242 is locked to the stop position 2412. Due to the effect of the second stopper 2232, the space between the terminal block 2400 and the core 2210 is convenient for wiring arrangement, and also reduces the direct impact of the heat of the coil winding on the terminal block 2400.

[0066] Combination Figure 5 As shown, in some embodiments of the present application, the water pump 100 also includes a base 3000, the shielding sleeve 2100 of the motor assembly 2000 is provided with a second cavity 2102, the core component 2200 and the terminal block 2400 are both required to be arranged in the second cavity 2102, the base 3000 is connected to the shielding sleeve 2100 to enclose the second cavity 2102, and the terminal block 2400 is located between the core component 2200 and the base 3000, and the water pump 100 can be installed to the target area through the base 3000.

[0067] Specifically, the core component 2200 and the terminal block 2400 are electrical components, and the second cavity 2102 is provided in the shielding sleeve 2100, and the base 3000 encloses the second cavity 2102, so that preliminary protection can be formed for the core component 2200 and the terminal block 2400. Since the terminal block 2400 is located between the core component 2200 and the base 3000, if the terminal block 2400 fails, the terminal block 2400 can be repaired when the base 3000 is removed, which is convenient and quick, and the terminal block 2400 is closer to the base 3000 than the core component 2200, so the power line connected to the terminal block 2400 can pass through the area where the base 3000 is located and connect to the external power supply through a shorter path, reducing the complexity of the wiring.

[0068] For example, the shielding cover 2100 is the main structural component of the motor assembly 2000, which supports the core component 2200 and the rotor component 2300 and provides a basis for the operation of the motor assembly 2000. Generally speaking, the shielding cover 2100 is made of plastic material. Of course, the shielding cover 2100 can also be made of other materials. The shielding sleeve 2100 is provided with a first cavity 2101 and a second cavity 2102. The first cavity 2101 is open toward the pump body 1000, and the second cavity 2102 is open away from the pump body 1000. When assembling the motor assembly 2000, the rotor component 2300 can be conveniently inserted into the first cavity 2101 through the open end of the first cavity 2101, and the core component 2200 can be conveniently inserted into the second cavity 2102 through the open end of the second cavity 2102, so that the core component 2200 surrounds the rotor component 2300, and then the terminal block 2400 is connected to the core bracket 2220, and finally the base 3000 is connected to the shielding sleeve 2100. Since the second cavity 2102 is open away from the pump body 1000, it is difficult for water to enter the second cavity 2102 and cause damage to the water pump 100.

[0069] Combination Figure 5 As shown, in some embodiments of the present application, along the axial direction of the motor assembly, the projection area of ​​the wiring board 2400 is less than half of the projection area of ​​the shielding sleeve 2100, for example Figure 5 The terminal block 2400 shown is only a part of a roughly arc-shaped structure, which can effectively reduce the space occupied by the terminal block 2400, making it easier for staff to grab the terminal block 2400, thereby more conveniently installing the terminal block 2400 to the core bracket 2220. Since the size of the terminal block 2400 is reduced, the material cost can also be effectively reduced.

[0070] The second aspect of the present application discloses a water pump 100, which includes the above-mentioned motor assembly 2000, the motor assembly 2000 includes a core component 2200 and a terminal block 2400, the core component 2200 includes a core 2210 and a core bracket 2220, the core 2210 is arranged on the core bracket 2220, and the terminal block 2400 is connected to the core bracket 2220. The core bracket 2220 provides a connection structure for the installation of the terminal block 2400. When assembling the motor assembly 2000, the terminal block 2400 and the core component 2200 can be assembled together first or the core component 2200 and the terminal block 2400 can be assembled in sequence, and the terminal block 2400 is supported by the core component 2200. Based on the fixed design of the core component 2200, the terminal block 2400 can be fixed. It is understandable that the motor assembly 2000 of the water pump 100 adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0071] The third aspect of the present application further discloses a water heater, for example, the water heater is a gas water heater, the water heater includes a water pump 100, and the water flow is pressurized by setting the water pump 100. The water pump 100 includes a motor assembly 2000, the motor assembly 2000 includes a core component 2200 and a terminal block 2400, the core component 2200 includes a core 2210 and a core bracket 2220, the core 2210 is arranged on the core bracket 2220, and the terminal block 2400 is connected to the core bracket 2220. The core bracket 2220 provides a connection structure for the installation of the terminal block 2400. When assembling the motor assembly 2000, the terminal block 2400 and the core component 2200 can be assembled together or the core component 2200 and the terminal block 2400 can be assembled in sequence.
