Description

Technical Field

[0001] This utility model relates to a small household appliance, and in particular to a handheld blender. Background Technology

[0002] In the structural design of handheld mixers, the installation method of the buttons directly affects the structural complexity of the casing, production efficiency and manufacturing cost. Currently, there are two main installation schemes in the industry for handheld mixers with buttons installed on the side of the mixer, but both have obvious defects.

[0003] The first design adopts a split housing structure, which consists of two shells. The buttons are fixed to the shells with screws. The main purpose of designing the housing into two shells is to facilitate the screws that fix the buttons. However, the split structure inevitably requires a complex mating structure at the joint of the shells, which not only increases the design difficulty of the housing but also increases the processing complexity of the mold. At the same time, the assembly process of the two shells requires additional positioning and fixing steps, which reduces production efficiency. Furthermore, the product stability may be affected by loosening at the joint during long-term use.

[0004] The second option adopts an integrated housing structure, where the housing is a single, complete shell. The connection between the buttons and the housing is achieved through a snap-fit ​​mechanism. This requires a hook on the button and a corresponding hook hole on the housing. While this option avoids the assembly problems associated with separate housings, the hook holes on the housing undoubtedly increase the design complexity of the parts, leading to increased difficulty in mold processing. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a handheld mixer.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A handheld mixer includes a one-piece molded housing, which is a hollow structure with openings at both ends. A stirring blade driven by a motor is installed at the front end of the housing. A control board electrically connected to the motor is installed inside the housing. A button holder is slidably inserted into the rear end of the housing. A button for cooperating with a switch on the control board is installed on the button holder. An end cap for preventing the button holder from loosening is installed at the rear end of the housing. A first through hole for exposing the button is provided on the side wall of the housing.

[0007] The rear end of the housing is provided with a rib, which forms a groove with the inner wall of the housing. The button fixing bracket is provided with a sliding part corresponding to the groove, and the sliding part is slidably inserted into the groove.

[0008] The rear end of the button holder is provided with a limiting part, which abuts against the end of the rib.

[0009] The end cap is provided with an abutting part along the sliding direction of the button fixing bracket, and the abutting part abuts against the limiting part.

[0010] The button holder is provided with a snap-fit ​​hole, and the button is provided with a snap-fit ​​part corresponding to the snap-fit ​​hole, and the snap-fit ​​part is snapped into the snap-fit ​​hole.

[0011] The button is provided with an insert strip, and the buckle part is located at the end of the insert strip. The insert strip can be movably inserted into the buckle hole.

[0012] The button has a center post for pressing the switch on the control panel. The button mounting bracket has a second through hole corresponding to the abutment post, and the abutment post can be movably inserted into the second through hole.

[0013] The beneficial effects of this utility model are as follows: A stirring blade driven by a motor is installed at the front end of the casing. A control board electrically connected to the motor is installed inside the casing. A button mounting bracket is slidably inserted into the rear end of the casing, and a button for use with the switch on the control board is installed on the button mounting bracket. An end cap for preventing the button mounting bracket from loosening is installed at the rear end of the casing. Installation is simple, the fixing is reliable, and product quality is guaranteed. The side wall of the casing has a first through hole for exposing the button. Compared to conventional mixers, the casing of this application only needs to have a first through hole for exposing the button, eliminating the need for additional complex structures such as snap-fit ​​holes for fixing the button. This makes the overall structure of the casing simpler, significantly reducing the injection molding cycle and mold structure difficulty. Furthermore, by eliminating structures such as snap-fit ​​holes, the first through hole can be made into more shapes, thus eliminating restrictions on the appearance of the button.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0018] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0019] Reference Figure 1-6 A handheld mixer includes a one-piece molded casing 1, which is a hollow structure with openings at both ends. A stirring blade 3 driven by a motor 2 is installed at the front end of the casing 1. A control board 4 electrically connected to the motor 2 is installed inside the casing 1. A button mounting bracket 5 is slidably inserted at the rear end of the casing 1. A switch (such as a joystick) for connecting to the control board 4 is mounted on the button mounting bracket 5. Figure 2 , 6 As shown in Figure A, the button 6 is used in conjunction with the housing 1. The rear end of the housing 1 is equipped with an end cap 7 to prevent the button fixing bracket 5 from loosening. The installation is simple and the fixing is reliable, which can ensure product quality. The side wall of the housing 1 is provided with a first through hole 8 for exposing the button 6. Compared with conventional mixers, the housing 1 of this application only needs to be provided with the first through hole 8 for exposing the button 6. There is no need to design additional complex structures such as snap-fit ​​holes to fix the button 6, making the overall structure of the housing 1 simpler and significantly reducing the injection molding cycle and mold structure difficulty of the housing 1. In addition, after eliminating the snap-fit ​​hole and other structures, the first through hole 8 can be set to more shapes (for conventional mixers, due to the presence of snap-fit ​​holes and other structures, these structures are closely related to the first through hole in space. From the perspective of mold processing, when such fixing structures and the first through hole exist on the housing at the same time, the mold needs to form these structures at the same time. If the shape of the first through hole is set arbitrarily, it may lead to the complexity of the mold cavity structure, increasing the processing difficulty and cost), thereby eliminating the appearance restrictions on the button.

[0020] The rear end of the housing 1 is provided with a rib 9, which forms a groove 10 with the inner wall of the housing 1. The button fixing bracket 5 is provided with a sliding part 11 corresponding to the groove 10. The sliding part 11 slides into the groove 10. The assembly process does not require complicated tools, can be quickly positioned and installed, and can also ensure the installation accuracy of the button fixing bracket 5 in the housing 1 and avoid shaking.

[0021] Furthermore, a limiting part 19 is provided at the rear end of the button fixing bracket 5. The limiting part 19 abuts against the end of the rib 9 and is used to position the sliding position of the button fixing bracket 5 to ensure that the button 6 can be adapted to the switch on the control board 4 after the button fixing bracket 5 is installed.

[0022] Furthermore, the end cover 7 is provided with an abutting part 12 along the sliding direction of the button fixing bracket 5. The abutting part 12 abuts against the limiting part 19. When the end cover 7 is installed, it will restrict the button fixing bracket 5 within the sliding groove 10 and prevent it from retracting, thereby completing the fixing of the button fixing bracket 5.

[0023] The button fixing bracket 5 is provided with a snap-fit ​​hole 13, and the button 6 is provided with a snap-fit ​​part 14 corresponding to the snap-fit ​​hole 13. The snap-fit ​​part 14 is snapped into the snap-fit ​​hole 13.

[0024] Furthermore, the button 6 is provided with an insert strip 15, and the latching part 14 is provided at the end of the insert strip 15. The insert strip 15 can be movably inserted into the latching hole 13. When the button 6 is completed, the button 6 can move along the length direction of the insert strip 15, that is, the button 6 can be pressed normally.

[0025] During installation, the button 6 needs to be installed on the button holder 5 first. Then, adjust the positions of the button holder 5 and the button 6 so that the button 6 is at the top. At this time, the button 6 sinks to the lowest point due to gravity. Then, the button holder 5 can be slid into the slide groove 10. When installing the control board 4, the housing 1 needs to be adjusted so that the button 6 is at the bottom. At this time, the button 6 protrudes from the first through hole 8 due to gravity. After the control board 4 is installed, the side of the button 6 on the surface protrudes from the first through hole 8, while the side of the button 6 on the bottom surface is restricted by the control board 4, preventing the button 6 from exiting from the first through hole 8. That is, at this time, the first through hole 8 restricts the movement of the button 6 along the sliding direction of the button holder 5, thereby limiting the button holder 5. At this time, the limitation of the button holder 5 is only the limitation of the button 6 by the first through hole 8, and the strength is low. Only after the end cover 7 is installed can the button holder 5 form sufficient fixing strength.

[0026] The button 6 has a center with an abutment post 16 for pressing the switch on the control board 4. The button mounting bracket 5 has a second through hole 17 corresponding to the abutment post 16, and the abutment post 16 can be movably inserted into the second through hole 17.

[0027] This application also includes conventional accessories such as a stirring splash guard 18 for preventing water or food from splashing during stirring by the stirring blades 3.
