Description

Technical Field

[0001] This utility model relates to the field of motor accessories, and in particular to a connection structure for a stirring motor. Background Technology

[0002] In electric sprayers, a stirring motor is typically connected to a stirring blade to agitate the liquid medicine in the sprayer's tank and prevent sedimentation.

[0003] To connect the mixing motor, one existing solution is to connect the mixing motor to a motor mounting plate, which is then connected to the main body of the electric sprayer. The connection between the mixing motor and the motor mounting plate is typically a screw connection.

[0004] Because the mixing motor is small in size, the screws connecting the mixing motor and the motor connecting plate must be of a smaller size. Small screws not only make assembly difficult and time-consuming, but also increase the risk of stripping the threads, resulting in an unreliable connection. Utility Model Content

[0028] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0029] This utility model embodiment provides a connection structure for a stirring motor, such as... Figure 1-7 As shown, it includes a stirring motor 1 and a motor connecting plate 2, wherein:

[0030] A first positioning structure 3 is provided on the front end face of the stirring motor 1, and a second positioning structure 4 is provided on the rear end face of the motor connecting plate 2. The front end face of the stirring motor 1 in this invention refers to the end face where the output shaft 5 of the stirring motor 1 is located; correspondingly, the rear end face of the stirring motor 1 refers to the end face opposite to the end face where the output shaft 5 of the stirring motor 1 is located. Similarly, the orientation definitions of the front end face and the rear end face of the motor connecting plate 2 are consistent with the orientation definitions of the front end face and the rear end face of the stirring motor 1.

[0031] The rear end face of the motor connecting plate 2 contacts the front end face of the stirring motor 1, and the first positioning structure 3 and the second positioning structure 4 cooperate to restrict the relative movement of the stirring motor 1 and the motor connecting plate 2 along the circumference of the stirring motor 1.

[0032] The motor connecting plate 2 is provided with a side wall positioning structure 6 that contacts the side wall of the stirring motor 1. The side wall positioning structure 6 restricts the relative movement of the stirring motor 1 and the motor connecting plate 2 along the radial direction of the stirring motor 1.

[0033] The motor connecting plate 2 is provided with an end face positioning structure 7 that contacts the rear end face of the stirring motor 1. The end face positioning structure 7 restricts the relative movement of the stirring motor 1 and the motor connecting plate 2 along the axial direction of the stirring motor 1.

[0034] This invention achieves the connection between the motor connecting plate 2 and the stirring motor 1 through the arrangement of a first positioning structure 3, a second positioning structure 4, a side wall positioning structure 6, and an end face positioning structure 7, and restricts the relative movement of the two in the circumferential, radial, and axial directions, thus fixing the motor connecting plate 2 and the stirring motor 1. All the aforementioned positioning structures of this invention are contact-type positioning structures, without the use of screws. This invention avoids the existing technology of connecting the motor connecting plate 2 and the stirring motor 1 with screws, making assembly simple, convenient, and the connection reliable.

[0035] As an example, one of the first positioning structure 3 and the second positioning structure 4 is a positioning post and the other is a positioning hole. The positioning post is inserted into the positioning hole, and the positioning post is adapted to the cross-sectional shape of the positioning hole.

[0036] When the cross-sectional shape of the positioning pin and positioning hole is circular, there are at least two sets of positioning pins and positioning holes. The circumferential movement is restricted by the cooperation of the two sets of positioning pins and positioning holes.

[0037] When the cross-sectional shape of the positioning pin and the positioning hole is non-circular, the number of positioning pins and positioning holes is at least one set. The circumferential movement is restricted by the cooperation of the non-circular positioning pins and positioning holes.

[0038] Preferably, the first positioning structure 3 is a positioning hole and the second positioning structure 4 is a positioning post. The screw holes that exist on the existing stirring motor 1 can be used as positioning holes directly, without the need to redesign the structure of the stirring motor 1.

[0039] Furthermore, the side wall positioning structure 6 is a positioning plate set on the rear end face of the motor connecting plate 2. The inner wall of the positioning plate has a contact surface that is adapted to the shape of the side wall of the stirring motor 1, thus restricting radial movement.

[0040] There is at least one positioning plate. When there are multiple positioning plates, they are distributed around the circumference of the stirring motor 1. Whether there is one or multiple positioning plates, all positioning plates need to surround more than half of the side wall of the stirring motor 1 in the circumference, that is, surround it by more than 180 degrees.

[0041] As a preferred embodiment, there are four positioning plates, arranged with their centers spaced 90° apart. Alternatively, there may be only one positioning plate, which is a complete annular positioning plate that surrounds the sidewall of the stirring motor 1 in a 360° direction.

[0042] The aforementioned end-face positioning structure 7 includes a barb structure, which is connected to the motor connecting plate 2 via a connecting part 8. The barb structure hooks onto the rear end face of the stirring motor 1, restricting axial movement. For a secure connection, at least two barb structures are used.

[0043] The connecting part 8 can be a connecting plate. The barb structure can be connected to the rear end face of the motor connecting plate 1 or to the positioning plate via the connecting plate. The inner wall of the connecting plate can have a contact surface adapted to the shape of the side wall of the stirring motor 1.

[0044] With the connection structure described above, it is only necessary to clip the stirring motor 1 onto the motor.

[0045] The motor connecting plate 2 has a through hole 9 for the output shaft 5 of the stirring motor 1 to pass through, and the front end face of the motor connecting plate 1 is provided with a main body connection structure for connecting with the main body of the electric sprayer. The main body connection structure may include screw holes 10 and connecting grooves 11, etc.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
