Description

Technical Field

[0001] The utility model relates to the field of small household appliances, in particular to a novel wire winding mechanism and a range hood. Background Art

[0002] In some small household appliances, there are situations where two parts need to move relative to each other during use. At this time, since the two parts are electrically connected, the power cord connecting the two parts is prone to entanglement or random movement, resulting in blocked movement. Although a wire winding mechanism can be used to reasonably arrange the power cord between the parts, the existing wire winding mechanisms have complex structures, large volumes, and are inconvenient to install. They are not suitable for installation between parts and have low usability in small devices such as household appliances.

[0003] According to the above, the structure of the existing wire winding mechanism needs to be further improved. Summary of the Utility Model

[0004] The first object of the utility model is to overcome the deficiencies of the existing wire winding mechanism with complex structure and large space occupation, and provide a novel wire winding mechanism. Through the combination of two wire protection grooves and the fixed shaft and movable shaft arranged on the wire protection grooves, by sliding to control the distance between the wire protection grooves and between the two shafts, the movement speed of the two shafts is the same as that of the wire protection grooves, so that both can move smoothly. Thus, the power cord wound around the two shafts always remains taut, achieving the effects of non-entanglement and non-random movement of the power cord.

[0005] To achieve the above object, the utility model adopts the following technical solution: A novel wire winding mechanism, comprising a first moving structure and a second moving structure. The first moving structure is slidably arranged within the second moving structure. A fixed shaft is provided on the first moving structure, and a movable shaft is slidably provided on the second moving structure. The power cord winds back and forth around the fixed shaft and the movable shaft.

[0006] Through the cooperation of the wire protection grooves with the fixed shaft and the movable shaft, when the wire winding mechanism is stretched, through the sliding between the wire protection grooves and the sliding of the movable shaft, the moving-away speed of the wire protection grooves is equal to the approaching speed between the two shafts. When the wire winding mechanism contracts, through sliding, the approaching speed of the wire protection grooves is equal to the moving-away speed between the two shafts. That is, the change in the distance between the two shafts is always opposite and equal to the change in the distance between the wire protection grooves. Then, the movement speed of the power cord wound between the two shafts is synchronized with that of the wire protection grooves, and both can move smoothly, avoiding the situation of messy and knotted power cords. Compared with the prior art, the novel wire winding mechanism of the utility model has a simple structure, occupies less space, is suitable for small devices with moving mechanisms such as household appliances, and keeps the power cords in the device neat and orderly.

[0007] Preferably, the first moving structure includes a first wire groove protector which is formed by enclosing a first bottom plate and a first side plate. The second moving structure includes a second wire groove protector which is formed by enclosing a second bottom plate and a second side plate. At least a part of the outer wall of the first bottom plate coincides with at least a part of the inner wall of the second bottom plate, and at least a part of the outer wall of the first side plate coincides with at least a part of the inner wall of the second side plate. The first wire groove protector and the second wire groove protector are both enclosed by three sides and at least partially coincide, which can limit the movement direction of the second wire groove protector and make the second wire groove protector slide accurately along the extension direction of the first wire groove protector.

[0008] Preferably, the fixed shaft is arranged on the first side plate and located at the end of the first wire groove protector.

[0009] Preferably, an activity groove is provided on the second side plate, and the activity shaft is slidably arranged on the activity groove, and shaft caps are arranged on both sides of the activity shaft. When the wire winding mechanism stretches, the wire groove protector moves away, and the activity shaft moves on the activity groove in the direction close to the fixed shaft. The cap shaft can prevent the activity shaft from swaying left and right.

[0010] Preferably, the power cord includes a first line segment, a second line segment, a third line segment, a first arc segment and a second arc segment. One end of the first line segment is connected to one end of the second line segment through the first arc segment wound around the fixed shaft. The other end of the second line segment is connected to the third line segment through the second arc segment wound around the activity shaft. The other end of the first line segment and the other end of the third line segment extend outward respectively.

[0011] When the wire winding mechanism stretches, the second wire groove protector moves away from the first wire groove protector. Since the second line segment and the third line segment are sequentially connected to both sides of the activity shaft and the two line segments are connected by the second arc segment, according to the principle of the pulley group structure, the total advancing distance of the second line segment and the third line segment is equal to the distance that the wire groove protector moves away. The advancing distance of the second line segment and the third line segment respectively is half of the distance that the wire groove protector moves away, that is, the approaching speed between the fixed shaft and the activity shaft is half of the moving away speed of the wire groove protector. At this time, the activity shaft is made to approach the fixed shaft at half of the moving away speed of the wire groove protector, so that the approaching speed between the two shafts is equal to the moving away speed between the two wire groove protectors. When the wire winding mechanism contracts, the second wire groove protector approaches the first wire groove protector, and the third line segment extending on the second wire groove protector advances following the second wire groove protector. According to the principle of the pulley group structure, at this time, the reduced length of the third line segment is equal to the increased length of the second line segment, that is, the moving speed of the activity shaft is consistent with the moving speed of the first wire groove protector. Then, the moving away speed between the two shafts is equal to the approaching speed between the two wire groove protectors. In these two cases, since the moving speed between the two shafts is equal to the moving speed between the two wire groove protectors, the moving speed of the power cord wound between the two shafts is equal to the moving speed between the two wire groove protectors, so that the power cord maintains dynamic balance, does not wind, does not move randomly, and is always taut between the two shafts.

[0012] Preferably, a limiting groove is provided on the first bottom plate, and a limiting pin is provided on the second bottom plate. The limiting pin is slidably arranged on the limiting groove. The limiting pin and the limiting groove are respectively arranged on the second wire protection groove and the first wire protection groove to limit the movement direction of the first wire protection groove, so that the first wire protection groove will not shake left and right.

[0013] Preferably, a first limiting part and a second limiting part are respectively provided on the upper and lower parts of the first side plate. The widths of the first limiting part and the second limiting part are greater than the width from the first bottom plate to the movable groove. A sliding part is provided in the middle of the first side plate, and the width of the sliding part is less than the width from the first bottom plate to the movable groove.

[0014] The first limiting part and the second limiting part are used to limit the movement range of the movable shaft when the wire winding mechanism contracts or stretches. When the wire winding mechanism contracts, the second wire protection groove slides upward. At this time, the overlapping area of the first side plate and the second side plate gradually increases. Since the width of the first limiting part is greater than the width from the first bottom plate to the movable groove, as the first limiting part overlaps with the movable groove, the upper part of the movable groove is gradually blocked, and the upper movement range of the movable shaft is limited. When the wire winding mechanism stretches, the second wire protection groove slides downward, and the second limiting part at the bottom gradually approaches the movable groove. Since the width of the second limiting part is greater than the width from the first bottom plate to the movable groove, as the second limiting part overlaps with the movable groove, the lower part of the movable groove is gradually blocked, and the lower movement range of the movable shaft is limited. When the sliding part overlaps with the movable groove, since the width of the sliding part is less than the width from the first bottom plate to the movable groove, the movement range of the fitting part of the sliding part and the movable groove is not limited.

[0015] Preferably, a first mounting plate is provided on the upper side of the first bottom plate. The first mounting plate, the first bottom plate and the first side plate enclose. A second mounting plate is provided outside the second bottom plate, and the second mounting plate is located below the second bottom plate. The mounting plate is used to respectively mount the left and right sides of the wire winding mechanism on different parts.

[0016] Preferably, a first mounting hole is provided on the first mounting plate, and a second mounting hole is provided on the second mounting plate.

[0017] Another object of the present invention is to provide a range hood, including a machine body, a pull-out plate and the novel wire winding mechanism of the above solution. The pull-out plate is arranged in the machine body through a slide rail. The first wire protection groove is arranged on the machine body, and the second wire protection groove is arranged on the pull-out plate, so that the power cord is at least isolated from the slide rail. Compared with the prior art, since the above solution is applied to the range hood of the present invention, when the pull-out plate is slid up and down, the power cord connecting the pull-out plate and the machine body does not affect each other with the slide rail, is not entangled, and is neat and orderly.

[0031] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by "upper", "lower", "left", "right", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0032] Embodiment 1:

[0033] See Figures 1 to 2 , this embodiment discloses a novel wire winding mechanism 1, which includes a first moving structure 2 and a second moving structure 3. The first moving structure 2 is slidably arranged in the second moving structure 3. A fixed shaft 4 is arranged on the first moving structure 2, and a movable shaft 5 is slidably arranged on the second moving structure 3. A power cord 6 is wound back and forth around the fixed shaft 4 and the movable shaft 5. Through the mutual sliding between the first moving structure 2, the second moving structure 3, and the movable shaft 5 in the novel wire winding mechanism 1 of this solution, the distance between the two shafts changes with the change in the distance between the two moving structures. Under this synchronous movement, the power cord 6 wound between the two shafts can maintain dynamic stability and always remain in a taut state without entanglement.

[0034] See Figures 1 to 7 , to make the second moving structure 3 move along the extending direction of the first moving structure 2, the first moving structure 2 includes a first wire groove 21, which is enclosed by a first bottom plate 22 and a first side plate 23.

An activity groove 331 is arranged on the second side plate 33, and the movable shaft 5 is slidably arranged on the activity groove 331. Shaft caps are arranged on both sides of the movable shaft 5. The activity groove 331 in this solution can adjust the distance between the two shafts according to the relative position of the wire grooves, so that the change in the distance between the two shafts is synchronized with the change in the distance between the wire grooves.

[0036] See Figure 8, the power cord 6 includes a first line segment 61, a second line segment 62, a third line segment 63, a first arc segment 64, and a second arc segment 65.

The other ends of the first line segment 61 and the third line segment 63 extend outward respectively. The power cord 6 in this solution is wound around the fixed shaft 4 and the movable shaft 5 in a certain winding manner, so that the power cord 6 has a certain degree of freedom of movement, can move correspondingly following the movement of the cable duct, maintain dynamic balance and tightness, and prevent the power cord 6 from being wound or moving randomly.

[0037] See Figures 1 to 7 , a limiting groove 221 is provided on the first bottom plate 22, and a limiting pin 321 is provided on the second bottom plate 32. The limiting pin 321 is slidably arranged on the limiting groove 221. The limiting pin 321 and the limiting groove 221 in this solution are respectively arranged on the second cable duct 31 and the first cable duct 21 to limit the movement direction of the first cable duct 21, so that the first cable duct 21 will not shake left and right.

[0038] See Figures 1 to 4 , in order to correspondingly limit the movement range of the movable shaft 5 in different states of the wire winding mechanism 1, a first limiting part 231 and a second limiting part 232 are respectively provided on the upper and lower parts of the first side plate 23. The widths of the first limiting part 231 and the second limiting part 232 are greater than the width from the first bottom plate 22 to the movable groove 331, and a sliding part 233 is provided in the middle of the first side plate 23. The width of the sliding part 233 is less than the width from the first bottom plate 22 to the movable groove 331.

[0039] See Figures 4 to 5 , a first mounting plate 7 is provided on the upper side of the first bottom plate 22. The first mounting plate 7 is enclosed by the first bottom plate 22 and the first side plate 23.

A first mounting hole 71 is provided on the first mounting plate 7, and a second mounting hole 81 is provided on the second mounting plate 8. The first mounting plate 7 and the second mounting plate 8 in this solution are used to respectively mount the wire winding mechanism 1 on two parts, so that the wires between the two parts connected by the power cord 6 are not wound.

[0040] The novel wire winding mechanism 1 of the present utility model, through the combination of two wire protection grooves and the fixed shaft 4 and the movable shaft 5 arranged on the wire protection grooves, controls the distance between the wire protection grooves and between the two shafts by sliding, so that the moving speeds of the two shafts are the same as that of the wire protection grooves, and both can move smoothly. Thus, the power cord 6 wound around the two shafts always remains taut, achieving the effects that the power cord 6 does not get entangled or move randomly. Compared with the prior art, the novel wire winding mechanism 1 of the present utility model has a simple structure and occupies a small space, and is applicable to small devices with moving mechanisms such as household appliances, keeping the power cord 6 in the device neat and orderly.

The first wire protection groove 21 is arranged on the machine body 91, and the second wire protection groove 31 is arranged on the pull-out plate 92, so that the power cord 6 is at least isolated from the slide rail. Compared with the prior art, since the above solution is applied to the oil fume machine 9 of the present utility model, when the pull-out plate 92 moves, the power cord 6 also moves on the wire winding mechanism 1, preventing the power cord 6 from being wound around the slide rail. Therefore, the power cord between the pull-out plate 92 and the machine body 91 remains neat and orderly.
