Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a flow guiding casing mechanism for a vacuum cleaner motor. Background Technique

[0002] A vacuum cleaner motor is equivalent to a motor with a load, and is composed of two parts: an electric device and a suction device. The electric device is the same as a general motor, mainly composed of a stator, an armature, carbon brushes, a casing, and a casing cover, and the electric components inside the electric device are protected through the casing.

[0003] For example, a motor casing with high heat dissipation efficiency disclosed in CN204408076U, which includes a casing; there are heat dissipation fins, bolt grooves, and placement platforms on the casing; the motor casing is mainly square, and the edges of the motor casing are slightly arc-shaped and protrude outward; multiple axial heat dissipation fins are arranged along the circumferential direction on the outer wall of the casing; four axial bolt grooves are arranged at the four corners of the casing, and end cover fixing through holes are arranged along the axial direction of the bolt grooves on the casing; the heat dissipation fins on the outer wall of the casing are designed in a T shape; there is a rectangular placement platform on one surface of the outer wall of the casing.

[0004] Among them, the following technical problems exist in the above-mentioned prior art: the main heat dissipation means of the existing motor casing depends on the heat dissipation fins on the outer wall when in use. Although the heat dissipation fins can play a certain heat dissipation effect, when the motor is in an overheated state during long-term operation, relying solely on a single heat dissipation fin is likely to reduce the heat dissipation efficiency of the motor itself. At the same time, the heat dissipation fins and the motor casing are of an integrally formed structure. When rust appears or damage occurs on the surface of the heat dissipation fins, it is not convenient to replace a certain one or several heat dissipation fins separately.

[0005] Therefore, we propose a flow guiding casing mechanism for a vacuum cleaner motor to facilitate solving the problems raised above. Content of the Utility Model

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Embodiment 1: Please refer to Figures 1-6 , the heat dissipation fins and the motor housing are of an integrally formed structure. When rust appears or damage occurs on the surface of the heat dissipation fins, it is not convenient to replace one or several heat dissipation fins separately. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0036] A flow - guiding housing mechanism for a vacuum cleaner motor, comprising a motor housing body 1, and heat - dissipating guide fins 2 for heat exchange with the outside air are circumferentially installed on the motor housing body 1; a plug - in slot 3 for facilitating the insertion of the heat - dissipating guide fins 2 is circumferentially provided on the motor housing body 1, and an inner concave portion 4 is formed by inward depression on the surface of the end of the heat - dissipating guide fin 2 away from the motor housing body 1. A connection slot 5 is provided on the heat - dissipating guide fin 2, and the heat - dissipating guide fin 2 is fixed to the motor housing body 1 by a locking bolt 6; a plurality of heat - dissipating guide fins 2 are evenly distributed at equal angles circumferentially on the motor housing body 1, and each heat - dissipating guide fin 2 is inserted into the plug - in slot 3 provided on the surface of the motor housing body 1, and a flow - guiding channel is formed between adjacent heat - dissipating guide fins 2. The outer wall of the lower end of the heat - dissipating guide fin 2 fits with the inner wall of the plug - in slot 3, and a plurality of inner concave portions 4 are evenly distributed on the heat - dissipating guide fin 2. Threaded holes for cooperating with the locking bolts 6 are provided on the surface of the motor housing body 1, and a plurality of locking bolts 6 are provided on the heat - dissipating guide fin 2, and the locking bolts 6 and the heat - dissipating guide fin 2 are in threaded connection.

[0037] When the motor housing body 1 generates heat, the heat of the motor housing body 1 can be absorbed by the heat - dissipating guide fins 2, and the heat - dissipating guide fins 2 contact the outside air for heat exchange to cool the motor housing body 1. The plug - in slots 3 and the connection slots 5 are evenly distributed on the heat - dissipating guide fins 2. The use of the plug - in slots 3 and the connection slots 5 can increase the contact area between the heat - dissipating guide fins 2 and the outside air, thereby improving the heat - exchange effect. Since the heat - dissipating guide fin 2 and the motor housing body 1 are connected to each other by the locking bolt 6, when the heat - dissipating guide fin 2 is damaged, the locking bolt 6 is unscrewed from the heat - dissipating guide fin 2 to release the fixation between the heat - dissipating guide fin 2 and the motor housing body 1, and then the heat - dissipating guide fin 2 is pulled out from the plug - in slot 3 on the motor housing body 1, so as to facilitate the replacement of the heat - dissipating guide fin 2.

[0038] Embodiment Two: The technical content disclosed in this embodiment is a further improvement based on the above - mentioned Embodiment One. The main heat - dissipating means of the existing motor housing relies on the heat - dissipating fins on the outer wall during use. Although the heat - dissipating fins can achieve a certain heat - dissipating effect, when the motor works for a long time and is in an overheated state, relying solely on a single heat - dissipating fin is likely to reduce the heat - dissipating efficiency of the motor itself. To further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 1-3 - Figure 6 shown;

[0039] One end of the motor housing body 1 is inlaid with a shunt ring 7, and the other end of the motor housing body 1 is inlaid with a current collecting ring 8. The current collecting ring 8 and the shunt ring 7 are connected to each other through a convection pipe 9, and the convection pipe 9 is located inside a receiving groove 10 which is opened on the motor housing body 1. A liquid infusion pipe 11 is fixedly connected to the side of the shunt ring 7, and a liquid discharge pipe 12 is fixedly connected to the side of the current collecting ring 8. The longitudinal sections of the shunt ring 7 and the current collecting ring 8 are both arranged in an annular structure, and the shunt ring 7, the current collecting ring 8 and the convection pipe 9 are all made of heat-conducting materials. A plurality of convection pipes 9 are installed between the shunt ring 7 and the current collecting ring 8, and the interiors of the shunt ring 7 and the current collecting ring 8 are both hollow structures, and the interiors of the shunt ring 7 and the current collecting ring 8 are communicated with each other through the convection pipe 9. The convection pipes 9 and the receiving grooves 10 are in one-to-one correspondence, and the outer wall of the convection pipe 9 fits against the inner wall of the receiving groove 10.

[0040] When the motor housing body 1 gets severely heated, water source is injected into the interior of the shunt ring 7 through the liquid infusion pipe 11. The water source inside the shunt ring 7 enters the interior of the current collecting ring 8 through the convection pipe 9. The flowing water source in the shunt ring 7, the convection pipe 9 and the current collecting ring 8 can exchange heat with the motor housing body 1, so as to accelerate the heat dissipation and cooling effect of the motor housing body 1 and prevent the motor housing body 1 from being in an overheated state.

[0041] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0042] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacement on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
