Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of kitchen appliances, and in particular to a handheld blender. Background Art

[0002] Traditional hand-held blenders are only equipped with a single-layer blade assembly to blend ingredients.

[0036] Below, the embodiment of the present utility model is described in detail with reference to the accompanying drawings.

[0037] like Figure 1 、 Figure 2 As shown, the embodiment of the present invention provides a hand-held blender, comprising:

[0038] Host 1;

[0039] The stirring shell includes a hollow connecting rod 2 and a stirring cover 3;

[0040] A first stirring assembly is disposed in the stirring housing, comprising a first rotating shaft assembly and a first blade assembly 5 located in the stirring cover 3. When the main unit 1 is docked with the stirring housing, the power output end of the main unit 1 is correspondingly engaged with the first rotating shaft assembly;

[0041] A second stirring assembly is disposed in the stirring housing, the second stirring assembly comprising a second rotating shaft assembly sleeved on the first rotating shaft assembly and a second blade assembly 7 located in the stirring cover 3, the second blade assembly 7 being located above the first blade assembly 5, and the second rotating shaft assembly and the first rotating shaft assembly being connected in a manner that can rotate synchronously and generate relative motion in the axial direction;

[0042] The adjusting mechanism is provided on the connecting rod 2, and the adjusting mechanism includes a sliding member 9 capable of axial movement and a driving member 8 for driving the sliding member 9 to move axially. The first rotating shaft assembly or the second rotating shaft assembly is connected to the sliding member 9 for relative movement driven by the sliding member 9 to adjust the distance between the first knife assembly 5 and the second knife assembly 7.

[0043] Based on the above, it can be seen that this embodiment, by providing two mutually nested stirring components, provides the blender with upper and lower blade assemblies. Furthermore, by providing an adjustment mechanism, the relative distance between the upper and lower blade assemblies can be adjusted by driving the rotating shafts within the different stirring components up and down, allowing the blender to switch between single-layer and double-layer cutting modes, thereby achieving the desired effect of stirring different types of ingredients. Furthermore, by adjusting the relative distance, the height of the components within the stirring housing 3 can be adjusted to control the size of the cut food particles. Furthermore, this embodiment uses the first stirring component to drive the second stirring component, thus achieving dual-axis drive based on the same main unit 1, which is cost-effective.

[0044] In one embodiment, the first rotating shaft assembly includes a first rotating shaft 4 and a first bearing assembly, the first knife assembly 5 is arranged at the lower end of the first rotating shaft 4, the first bearing assembly is sleeved on the first rotating shaft 4, and allows the first rotating shaft 4 to rotate relative to the first bearing assembly, but prohibits the first rotating shaft 4 from moving up and down relative to the first bearing assembly.

[0045] Specifically, the first bearing assembly includes a first bearing 10 and two shaft-mounted retaining rings 11 located on the upper and lower sides of the first bearing 10, respectively. The first rotating shaft 4 is provided with two slots. The first bearing 10 is sleeved on the first rotating shaft 4 at a position between the two slots. The two shaft-mounted retaining rings 11 are respectively disposed in the two slots, so that the first bearing 10 and the first rotating shaft 4 are fixed in the axial direction. That is, the two form a whole and cannot move relative to each other in the axial direction, but only allow relative rotation. The location of the first bearing assembly on the first rotating shaft 4 is not fixed and can be determined according to the need to drive the shaft body to move up and down.

[0046] The host 1 is provided with a driving mechanism, such as a motor, and a connecting portion is provided on the top of the first rotating shaft 4. The first rotating shaft 4 passes through the connecting rod 2, and the top end extends out of the connecting rod 2 for detachable connection with the power output end of the driving mechanism.

[0047] Furthermore, the second rotating shaft assembly includes a hollow second rotating shaft 6, a second bearing 12 and a transmission member 13, the second knife assembly 7 is arranged at the lower end of the second rotating shaft 6, the hollow second rotating shaft 6 is sleeved on the first rotating shaft 4, the second bearing 12 is sleeved on the second rotating shaft 6, the transmission member 13 is sleeved on the first rotating shaft 4, and is connected to the second rotating shaft 6 to transmit and connect the first rotating shaft 4 and the second rotating shaft 6 so that they can rotate synchronously.

[0048] In one embodiment, if Figure 3 and Figure 4 As shown, the transmission member 13 is hollow cylindrical, and the second rotating shaft 6 is fixedly sleeved on the outside of the transmission member 13. The transmission member 13 is sleeved on the first rotating shaft 4. The transmission member 13 and the first rotating shaft 4 are respectively provided with a slide groove and a slider along the axial direction. The slider is limited in the slide groove and can move along the slide groove when the first rotating shaft 4 moves up and down. At the same time, it can generate a radial force with the slide groove when the first rotating shaft 4 rotates, thereby driving the second rotating shaft 6 to rotate synchronously. In other words, the first rotating shaft 4 can move axially relative to the transmission member 13 within a certain range based on the sliding relationship between the slide groove and the slider, but cannot rotate relative to the transmission member 13. The transmission member 13 and the first rotating shaft 4 can only rotate synchronously. Therefore, based on this arrangement, the effect of using the host 1 to drive the first rotating shaft 4 and the first rotating shaft 4 to drive the second rotating shaft 6 can be achieved, that is, the effect of achieving dual-axis drive based on a single host 1 is achieved.

[0049] The second bearing 12 is fixed in the connecting rod 2 and adjacent to its lower end area to prevent the second rotating shaft 6 from moving up and down, and only allows it to rotate. Sealing rings are provided between the connecting rod 2 and the second rotating shaft 6, and between the second rotating shaft 6 and the first rotating shaft 4. The first bearing assembly is arranged on the first rotating shaft 4 outside the adjustment mechanism and is connected to the sliding member 9. The first rotating shaft 4 moves up and down relative to the second rotating shaft 6 through the transmission of the first bearing assembly, thereby achieving adjustment of the relative position between the first knife assembly 5 and the second knife assembly 7. That is, in this embodiment, the distance adjustment between the two knife assemblies is achieved by driving the first rotating shaft 4 up and down. In this embodiment, the length of the second rotating shaft 6 can be set shorter to save costs.

[0050] When applied, for example Figure 3 As shown, the first rotating shaft 4 is driven to move so that the first knife assembly 5 is separated from the second knife assembly 7 with a certain interval, and the double knife cutting mode can be realized at this time. Figure 4 As shown, the first rotating shaft 4 is driven to move so that the first knife assembly 5 and the second knife assembly 7 are close to each other and almost integrated into one, so that a single-knife cutting mode can be realized, and the user can flexibly switch the mode according to actual cutting needs.

[0051] In another embodiment, Figure 5 As shown, the adjustment mechanism also includes a stirring rod connector 14 installed at the upper end of the connecting rod 2 for receiving the main unit 1, that is, the stirring shell is connected to the main unit 1 through the stirring rod connector 14. In this embodiment, the adjustment mechanism is entirely located at the top of the connecting rod 2. The adjustment mechanism is hollow as a whole. The first rotating shaft 4 passes through the stirring rod connector 14, that is, it passes through the entire adjustment mechanism to connect with the main unit 1. The first bearing assembly is fixed in the stirring rod connector 14, that is, in this embodiment, the first bearing assembly is fixed on the first rotating shaft 4 located in the adjustment mechanism and is fixedly connected to the corresponding stirring rod connector 14 so that the axial position of the first rotating shaft assembly as a whole is fixed. The transmission member 13 is fixedly connected to the sliding member 9. The second rotating shaft 6 moves up and down relative to the first rotating shaft 4 along with the sliding member 9 through the transmission member 13, thereby adjusting the relative position between the first knife assembly 5 and the second knife assembly 7. That is, in this embodiment, the distance between the two knife assemblies is adjusted by driving the second rotating shaft 6 up and down. In this embodiment, the length of the second rotating shaft 6 needs to be set slightly longer to facilitate the connection between the transmission member 13 and the sliding member 9 .

[0052] Furthermore, if Figure 6As shown, the stirring rod connector 14 includes a hollow connecting portion for the main unit 1 and a mounting portion connected to the connecting portion. The connecting portion for the main unit 1 is hollow, bowl-shaped, and may also be other shapes to match the main unit 1. The connecting portion for the main unit 1 extends beyond the connecting rod 2 and is located outside the upper end of the connecting rod 2. The mounting portion is hollow, cylindrical, and inserted into the connecting rod 2. The sliding member 9 is slidably connected to the mounting portion, and the driving member 8 is mounted on the connecting portion for the main unit 1 and connected to the sliding member 9.

[0053] Specifically, the sliding member 9 is a sliding sleeve that is sleeved on the mounting portion. The sliding member 9 and the mounting portion are respectively provided with a guide groove 16 and a guide rail 15 located in and capable of sliding along the guide groove 16 in the axial direction. The guide groove 16 and the guide rail 15 are used to limit the axial movement direction and movement distance of the sliding member 9.

[0054] The upper end of the sliding member 9 is provided with an external thread, and the driving member 8 is annular, one end of which matches the outer shape of the connecting part of the main unit 1, and the other end is provided with an internal thread, which extends into the connecting rod 2 and is threadedly connected to the sliding member 9. One end of the driving member 8 is sleeved on the outside of the connecting part of the main unit 1, and an annular groove and an annular protrusion are provided between the connecting part of the main unit 1 to achieve the effect of being able to rotate relative to the connecting part of the main unit 1. When the user wants to adjust the positional relationship between the two knife assemblies, the sliding member 9 can be moved up and down by rotating the driving member 8, thereby achieving position adjustment between the two knife assemblies. That is, the driving member 8 is equivalent to an adjustment knob, and rotating the knob can achieve height adjustment of the knife assembly, which is simple and convenient, and has outstanding effects.

[0055] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
