Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0070] The embodiments of the utility model installation structure, head shaking mechanism and electric appliance device will be described below in combination with Figures 1-12d

[0071] According to the embodiments of the utility model, an installation structure is provided, which is applied to a head shaking mechanism, the head shaking mechanism comprising a support 1 and a friction piece 2, and the installation structure comprising a rotating clamping mechanism, the rotating clamping mechanism being arranged on the support 1 and the friction piece 2, and the friction piece 2 being installed on the support 1 through the rotating clamping mechanism.

[0072] The installation structure only needs to be clamped through rotating operation without additional assembly parts, greatly reduces the installation parts, makes the installation of the friction piece 2 and the support 1 more stable and reliable, improves the stability and firmness of the friction piece 2 and the support 1 after installation, can simplify the installation operation, improves the installation efficiency and production efficiency, and thus reduces the product cost.

[0073] The installation structure of the embodiments is applied to a head shaking mechanism, and the head shaking mechanism is used to drive a rotatable device to swing. For example, when the head shaking mechanism is applied to an electric heater, the rotatable device is the main part of the electric heater, and the head shaking mechanism drives the main part of the electric heater to swing in the horizontal direction.

[0074] The head shaking mechanism comprises a support 1 and a friction piece 2, the support 1 is used for bearing and supporting, and other structures of the head shaking mechanism can be arranged or installed on the support 1. The friction piece 2 is also called a friction plate, and the friction piece 2 is mainly used to provide and adjust friction, plays the roles of anti-skid, transmission and shock absorption, and thus controls the running state and heat energy conversion efficiency of the electric heater.

[0075] In the embodiments, the installation structure comprises a rotating clamping mechanism, that is, the installation structure is clamped through rotating operation, and thus the installation of the friction piece 2 and the support 1 is realized. The installation structure is simple, has no redundant parts, has good reliability, is not easy to loosen, and is very convenient to install, which can improve the production efficiency and reduce the product cost.

[0076] Further, the rotating clamping mechanism comprises a first direction limiting structure, which is used to limit the friction piece 2 in the first direction after the friction piece 2 and the support 1 are installed. ​

[0077] The rotating clamping mechanism comprises a first direction limiting structure, which can limit the friction piece 2 in the first direction after the friction piece 2 is installed on the support 1. In the embodiment, the first direction is the axial direction of the rotating mechanism, as shown by the arrow a-a'. Figure 10 The first direction limiting structure can limit the loosening or shifting of the friction piece 2 in the axial direction, improve the structural reliability, and realize the self-locking of the friction piece 2 in the first direction, thereby improving the reliability and firmness of the installation of the friction piece 2 on the support 1.

[0078] Further, the first direction limiting structure comprises a first clamping part 301 and a second clamping part 302, one of which is arranged on the support 1, and the other is arranged on the friction piece 2. The first clamping part 301 is clamped into the second clamping part 302, and the second clamping part 302 limits the first clamping part 301 in the first direction. This first direction limiting structure is relatively simple and easy to manufacture, which is conducive to simplifying the installation structure and reducing the manufacturing cost.

[0079] In the embodiment, the first clamping part 301 is arranged on the friction piece 2, and the second clamping part 302 is arranged on the support 1. By rotating the first clamping part 301 or the second clamping part 302, the first clamping part 301 is clamped into the second clamping part 302, thereby realizing the installation of the friction piece 2 on the support 1. At the same time, the second clamping part 302 limits the first clamping part 301 in the first direction, and the friction piece 2 is self-locked.

[0080] As shown in Figure 4a and Figure 5 In the embodiment, the first clamping part 301 protrudes from the outer wall of the friction piece 2, and at least two first clamping parts 301 are arranged on the friction piece 2. Specifically, the first clamping part 301 is an arc-shaped protruding block structure, which has sufficient structural strength to realize the installation of the friction piece 2 on the support 1 and to realize the self-locking of the friction piece 2. In the embodiment, three first clamping parts 301 are arranged on the friction piece 2, and the three first clamping parts 301 are uniformly spaced along the circumference of the friction piece 2.

[0081] In other embodiments, the first clamping part 301 can be arranged on the support 1, and the second clamping part 302 can be arranged on the friction piece 2, as long as the first clamping part 301 and the second clamping part 302 can be clamped and rotated in cooperation. In addition, the number of first clamping parts 301 can also be two, four, five, etc. Moreover, at least two first clamping parts 301 can be unevenly spaced, as long as it does not affect the installation of the first clamping part 301 and the second clamping part 302.

[0082] Further, the side of the support 1 facing the friction member 2 is provided with a mounting surface 1011 perpendicular to the first direction, and the second clamping portion 302 cooperates with the mounting surface 1011 to limit the first clamping portion 301 in the first direction.

[0083] As shown in Figure 4a , the side of the support 1 facing the friction member 2 is provided with a mounting surface 1011 perpendicular to the first direction, and after the first clamping portion 301 is clamped into the second clamping portion 302, the second clamping portion 302 limits the first clamping portion 301 in one direction (as indicated by arrow a in Figure 10 ) of the first direction, and the other direction (as indicated by arrow a' in Figure 10 ) of the first direction is limited by the mounting surface 1011, so as to realize that the second clamping portion 302 cooperates with the mounting surface 1011 to limit the first clamping portion 301 in two directions of the first direction.

[0084] In other embodiments, the second clamping portion 302 can be directly formed with a clamping groove, and the extension direction of the clamping groove is consistent with the rotation direction of the first clamping portion 301, and at this time, after the first clamping portion 301 is clamped into the second clamping portion 302, the two side walls of the clamping groove can limit the first clamping portion 301 in two directions of the first direction.

[0085] Further, the side of the support 1 facing the friction member 2 is provided with a mounting wall 1012, the height direction of the mounting wall 1012 is consistent with the first direction, the second clamping portion 302 is arranged on the inner wall of the mounting wall 1012, and the second clamping portion 302 protrudes from the inner wall of the mounting wall 1012, and the second clamping portion 302 is provided in at least two, and the at least two second clamping portions 302 are arranged at intervals along the circumference of the support 1.

[0086] As shown in Figure 4a , the side of the support 1 facing the friction member 2 is provided with a mounting groove 101, the groove bottom of the mounting groove 101 is a mounting surface 1011, the side wall of the mounting groove 101 is a mounting wall 1012, the height direction of the mounting wall 1012 is consistent with the first direction, and the cross-sectional shape of the mounting groove 101 perpendicular to the first direction is circular, so the mounting wall 1012 is a cylindrical surface structure.

[0087] The second clamping portion 302 is arranged on the side wall of the mounting wall 1012, and the second clamping portion 302 protrudes from the inner wall of the mounting wall 1012 to form a clamping block structure, and the second clamping portion 302 is arranged along the inner wall of the mounting wall 1012 in the circumferential direction, so the second clamping portion 302 is an arc-shaped clamping block structure. The number and position of the second clamping portion 302 match the number and position of the first clamping portion 301, and in this embodiment, the second clamping portion 302 is provided in three, and the three second clamping portions 302 are uniformly and spacedly arranged along the circumference of the support 1.

[0088] In other embodiments, the number of second snap-fit ​​portions 302 can be two, three, five, etc., as long as it does not affect the installation of the first snap-fit ​​portions 301 and the second snap-fit ​​portions 302. Furthermore, the number of first snap-fit ​​portions 301 can be greater than, equal to, or less than the number of first snap-fit ​​portions 301, as long as the installation firmness after the first snap-fit ​​portions 301 and the second snap-fit ​​portions 302 are rotated and snapped together is ensured.

[0089] To ensure reliable support of the first latching part 302 by the second latching part 302, the height dimension of the second latching part 302 in the height direction (first direction) is greater than or equal to 3.5mm, so as to ensure the structural strength of the second latching part 302.

[0090] Furthermore, the second snap-fit ​​portion 302 is spaced apart from the mounting surface 1011, and the gap between the second snap-fit ​​portion 302 and the mounting surface 1011 forms a snap-fit ​​groove, in which the first snap-fit ​​portion 301 snaps into the snap-fit ​​groove.

[0091] The second snap-fit ​​portion 302 is spaced apart from the mounting surface 1011 by a certain distance, i.e., there is a gap, which forms a snap-fit ​​groove. After installation, the first snap-fit ​​portion 301 snaps into the snap-fit ​​groove. Understandably, in order to make the first snap-fit ​​portion 301 more stable and not loose after being installed in the snap-fit ​​groove, the gap between the second snap-fit ​​portion 302 and the mounting surface 1011 should match the height dimension of the first snap-fit ​​portion 301 along the first direction. For example, the first snap-fit ​​portion 301 can be interference-fitted with the snap-fit ​​groove.

[0092] Specifically, on the mounting wall 1012, there is a gap between adjacent second snap-fit ​​portions 302, and the size of the gap should be larger than the size of the first snap-fit ​​portion 301. During installation, the first snap-fit ​​portion 301 is first inserted into the gap between adjacent second snap-fit ​​portions 302, and then the friction member 2 or the rotating bracket 1 is rotated so that the first snap-fit ​​portion 301 is engaged in the snap-fit ​​groove between the second snap-fit ​​portion 302 and the mounting surface 1011. At this time, the second snap-fit ​​portion 302 and the mounting surface 1011 cooperate to jointly limit the first snap-fit ​​portion 301 in the first direction.

[0093] like Figure 3 As shown, three arc-shaped holes 202 are also provided on the bracket 1. The positions of the arc-shaped holes 202 correspond to the positions of the second snap-fit ​​portion 302. The function of the arc-shaped holes 202 is to facilitate the demolding of the second snap-fit ​​portion 302 of the bracket 1 during manufacturing. The arrangement of the arc-shaped holes 202 does not affect the fact that the first snap-fit ​​portion 301 is confined between the second snap-fit ​​portion 302 and the mounting surface 1011. For example, the circumferential dimension of the first snap-fit ​​portion 301 is larger than the circumferential dimension of the arc-shaped holes 202, so that the first snap-fit ​​portion 301 can be reliably confined between the second snap-fit ​​portion 302 and the mounting surface 1011.

[0094] Further, the rotating clamping mechanism further comprises a second direction limiting structure for limiting the friction piece 2 in the second direction after the friction piece 2 is installed on the support 1, and the second direction is arranged at an angle with the first direction.

[0095] In order to further ensure the stability of the friction piece 2 after installation, the rotating clamping mechanism further comprises a second direction limiting structure for limiting the friction piece 2 in the second direction after the friction piece 2 is installed on the support 1, and the second direction is arranged at an angle with the first direction, and the included angle between the first direction and the second direction can be an acute angle, a right angle, an obtuse angle, etc. In the embodiment, the first direction is perpendicular to the second direction, the first direction is the axial direction, and the second direction is the radial direction, so that the friction piece 2 is more stable after installation. Figure 10 Taking the angle of view as an example, the second direction is the direction indicated by the arrow b-b'.

[0096] After the first clamping part 301 is clamped with the second clamping part 302, the first clamping part 301 is limited in the clamping groove, and the first clamping part 301 is further limited in the second direction by the second direction limiting structure, so that the installation of the first clamping part 301 is more stable, and the friction piece 2 is more stable and reliable after installation.

[0097] Further, the second direction limiting structure comprises an installation wall 1012, and the first clamping part 301 abuts against the installation wall 1012 after the friction piece 2 is installed on the support 1.

[0098] In the embodiment, the first clamping part 301 is limited by the installation wall 1012, which fully utilizes the structure, so that the installation wall 1012 can not only be provided with the second clamping part 302, but also limit the first clamping part 301 in the second direction.

[0099] After the first clamping part 301 is clamped with the second clamping part 302, the first clamping part 301 is limited in the clamping groove in the first direction, and the outer edge of the first clamping part 301 can abut against the inner wall of the installation wall 1012, so that the first clamping part 301 cannot move in the second direction, thereby ensuring the stability of the installation of the friction piece 2.

[0100] Further, the rotating clamping mechanism further comprises a second direction limiting structure for limiting the friction piece 2 in the second direction after the friction piece 2 is installed on the support 1, and the second direction is arranged at an angle with the first direction.

[0101] The rotating clamping mechanism further comprises a driving piece 4, and the installation structure further comprises a driving piece installation and positioning mechanism, and the driving piece 4 is installed on the support 1 through the driving piece installation and positioning mechanism.

[0102] Further, the driving member mounting positioning mechanism comprises the mounting column 5 and the mounting plate 6 which are mounted in cooperation, one of the mounting column 5 and the mounting plate 6 is arranged on the support 1, and the other is arranged on the driving member 4.

[0103] In the embodiment, the mounting column 5 is arranged on the support 1, and the mounting plate 6 is arranged on the driving member 4, and in order to ensure the stability of the mounting of the driving member 4, two mounting columns 5 are arranged at a distance, and correspondingly, two mounting plates 6 are arranged at a distance, and the arrangement positions of the mounting plates 6 correspond to the arrangement positions of the mounting columns 5.

[0104] Specifically, the mounting column 5 is arranged on the side of the support 1 which faces the driving member 4, the length direction of the mounting column 5 is parallel to the first direction, the mounting plate 6 is arranged on the outer wall of the driving member 4, and the mounting plate 6 protrudes outwardly from the outer wall of the driving member 4, the plane on which the mounting plate 6 is arranged is perpendicular to the first direction (the plane on which the mounting plate 6 is arranged is parallel to the second direction), so as to facilitate the cooperation of the mounting column 5 and the mounting plate 6.

[0105] In other embodiments, the mounting column 5 can also be arranged on the driving member 4, and the mounting plate 6 can be arranged on the support 1, as long as the mounting column 5 and the mounting plate 6 can be mounted correspondingly.

Figure 11 As shown in the angle, the first end 1601 of the rib 16 is the upper end, and the second end 1602 is the lower end. The rib 16 is inclined from the first end 1601 to the second end 1602 towards the driving member 4, so that the rib 16 as a whole is similar to a triangular structure.

[0144] The driving member 4 is connected with the friction member 2 through a transmission assembly, and the avoiding gap 1501 of the rib plate 15 in the protection structure is used for avoiding the transmission assembly, so that the structure of the head shaking mechanism is more reasonable and compact, and the structure layout is facilitated.

[0145] The installation process of the head shaking mechanism of the embodiment will be described below with reference to the drawings:

[0146] Firstly, the friction piece 2 is placed into the accommodating space of the rotating disc 7, and the friction piece 2 is fixed with the rotating disc 7 by using three fourth screws 14, as shown in Figure 8 ;

[0147] Then, the support 1 is close to the friction piece 2, the connecting column 201 is passed through the limiting hole 102, and meanwhile each first clamping part 301 is inserted into the gap position between the adjacent second clamping parts 302 on the support 1, until the first clamping part 301 is beyond the second clamping part 302, then the support 1 or the combination of the friction piece 2 and the rotating disc 7 is rotated, so that the first clamping part 301 is rotated and clamped into the second clamping part 302, the first clamping part 301 is limited in the clamping groove between the second clamping part 302 and the mounting surface 1011, the limitation of the first clamping part 301 in the first direction and the second direction is realized, and meanwhile the self-locking of the friction piece 2 is realized, as shown in Figure 9 ;

[0148] Then, the two mounting plates 6 of the driving piece 4 are respectively butted with the two mounting columns 5 on the support 1, the positioning column 501 is inserted into one positioning hole 601, the quick positioning of the mounting plate 6 and the mounting column 5 is realized, and then the other positioning hole 601 is fastened and connected with the mounting column assembly hole 502 by using the first screw 11.

[0149] Finally, the end of the connecting rod 8 away from the crank 9 is fastened and connected with the connecting column 201, and thus the installation of the swing mechanism is completed.

[0150] After the driving piece 4 is installed on the support 1, the side of the shell 402 of the driving piece 4 facing the support 1 is abutted with the step 17, the step 17 limits the side of the shell 402 facing the support 1, and the side wall of the shell 402 is abutted with the rib plate 15 or the rib strip 16, the rib plate 15 and the rib strip 16 limit the side wall of the shell 402, so that the support and protection of the protection structure to the shell 402 are realized. In the process that the output shaft 401 of the driving piece 4 drives the friction piece 2 to rotate through the transmission assembly, the output shaft 401 will bear a certain bending moment and torque, due to the arrangement of the protection structure, the shell 402 is limited in the protection structure, the protection structure provides strong protection and support to the shell 402, the influence of the bending moment and the torque on the shell structure of the driving piece is weakened, the shell 402 of the driving piece 4 is not easy to be deformed, and even more not to be burst, the occurrence of the warping phenomenon is greatly reduced, the fatigue life of the shell of the driving piece is prolonged, the reliability and stability of the operation of the driving piece 4 are ensured, and the safety of the whole swing mechanism is improved.

[0151] Further, after the friction piece 2 is installed with the support 1 through the rotating clamping mechanism, the rotating clamping mechanism can limit the friction piece 2 in the first direction, limit the movement of the friction piece 2 in the axial direction, constrain the axial pulling action of the friction piece 2 on the output shaft 401, make the transmission assembly only move in the radial direction, and play another protective role on the shell 402 of the driving piece 4, further avoid the warping phenomenon of the driving piece shell structure due to the bending moment and torque, and reduce the possibility of overall structure instability. In this way, the protection structure and the mounting structure cooperate to double-protect the driving piece 4.

[0152] The embodiment also provides an electric appliance device comprising the above-mentioned swing head mechanism.

[0153] The electric appliance device realizes the installation of the friction piece 2 and the support 1 and the installation of the driving piece 4 and the support 1 in the swing head mechanism through the mounting structure of the embodiment, so that the friction piece 2, the driving piece 4 and the like do not have problems such as loosening and poor sealing caused by insufficient connection strength and fatigue deformation of the mounting structure during the working process of the electric appliance device, the installation difficulty of the swing head mechanism is reduced, the installation efficiency is improved, and the product cost is reduced. Further, the protection structure of the electric appliance device effectively supports and protects the driving piece shell, so that the shell 402 is not easy to deform and burst, the fatigue life of the driving piece shell is prolonged, and the safety of the entire swing head mechanism is improved.

[0154] In the embodiment, the electric appliance device is an electric heater, and the electric heater main body part can swing through the swing head mechanism to realize the function of blowing warm air in a large range.

[0155] Of course, the electric heater of the embodiment also has other structures and components that the existing electric heaters have, for example, when the electric heater is a voice electric heater, it also has a voice collection module and a control module, which will not be described in detail.

[0156] As shown in Figure 12a As shown in Figure 12b As shown in Figure 12c As shown in Figure 12dAs shown, when the connecting column 201 is moved to the other end of the limiting hole 102 under the driving of the connecting rod 8, the right swing angle of the electric heater body part is 40°. Thus, under the driving of the driving member 4 and under the constraint of the connecting rod 8 and the crank 9, the moving range of the friction member 2 is limited in the range of 0-80° (or expressed as -40°-40°), and the electric heater body part realizes the horizontal left-right swing function.
