[0027] Example 1

[0028] like Figures 1 to 3 The present embodiment discloses a hand-held blender, comprising a housing 10, a rotating shaft 20 disposed in the housing 10, and a blending blade 30 fixed to the lower end of the rotating shaft 20, the rotating shaft 20 is sleeved with a connecting piece 40, the upper end of the connecting piece 40 cooperates with the housing 10, and the lower end is connected to an inner pot 50, the blending blade 30 is located in the inner pot 50, and the inner pot 50 is connected to a flexible blade cover 60, which covers the outer side and the bottom of the inner pot 50.

[0029] The hand-held blender of the present embodiment can be used in conjunction with a driving device such as a motor (not shown). The rotating shaft 20 is connected to the output end of the driving device by transmission. The rotating shaft 20 is driven to rotate by the driving device, and then the stirring blade 30 is driven to perform a stirring action. The stirring blade 30 is inserted into a container containing liquid food or solid food. The stirring blade 30 is used to stir and mix liquid food such as dairy products, thick soup, rice paste, eggs, etc., or to crush solid food such as fruits, peanut kernels, walnut kernels, etc.

[0030] A connecting piece 40 is sleeved on the rotating shaft 20, the upper end of the connecting piece 40 cooperates with the outer shell 10, and the lower end is connected to the inner shell 50. The stirring blade 30 is located in the inner shell 50, and the stirring blade 30 is protected by the inner shell 50 to prevent the stirring blade 30 from hitting the container when rotating, causing damage to the container, and has a good protective effect; and the outer shell 10 and the inner shell 50 are assembled by the connecting piece 40, which can be disassembled and assembled compared with the traditional one-piece molding structure. If some parts are damaged, the parts can be quickly disassembled and replaced, thereby extending the service life and reducing the difficulty of disassembly and cleaning.

[0031] Usually, in order to improve the structural stability of the inner liner 50 and avoid deformation of the inner liner 50, so that a stable stirring space is formed inside the inner liner 50, the inner liner 50 is usually made of a material with higher hardness, such as stainless steel. However, if the inner liner 50 is directly exposed to the outside, for some containers with coatings, the edges and corners of the inner liner 50 are easy to scratch the container coating. Based on this problem, the inner liner 50 of this embodiment is connected to a flexible knife cover 60. The flexible knife cover 60 is made of a flexible material, such as silicone, and has a good elastic anti-collision effect. The outer side and the bottom of the inner liner 50 are covered by the flexible knife cover 60, thereby avoiding the exposure of the harder surface of the outer side and the bottom of the inner liner 50. When stirring, the flexible knife cover 60 contacts the inner wall of the container without damaging the inner wall coating of the container.

[0032] For further information, please refer to Figure 3 At least one scraper 61 is connected to the outside of the flexible knife cover 60. The scraper 61 is used to scrape the food located on the side and bottom of the container to prevent the food from piling up on the side and bottom of the container. The shape of the scraper 61 is designed according to the shape of the inner cavity of the container. The scraper 61 of this embodiment adopts a fish fin scraper, which can be suitable for containers with curved bottoms. The curvature and size of the fish fin scraper are not limited and are designed accordingly according to the specific model of the container.

[0033] Of course, the use of a fish fin scraper is only a preferred implementation of the scraper 61. In other embodiments, the scraper 61 can also be a straight scraper, a flat scraper, etc., and is not limited to a fish fin scraper.

[0034] It should be noted that scrapers 61 of different shapes can be arranged on the same flexible knife cover 60 at the same time. For example, a fish fin scraper, a straight scraper and a flat scraper can be arranged on the same flexible knife cover 60 at the same time. The user can choose to use a fish fin scraper, a straight scraper or a flat scraper to scrape the sides and bottom of the container according to the shape of the inner cavity of the container. To choose a fish fin scraper, a straight scraper or a flat scraper, just turn the handheld blender so that the fish fin scraper, the straight scraper or the flat scraper is facing the sides and bottom of the container. The conversion operation is also relatively simple.

[0035] Please refer to Figure 1 and Figure 2A protrusion 62 is connected to the inner side of the flexible knife cover 60, and the protrusion 62 extends into the inner pot 50. By setting the protrusion 62, when the food in the inner pot 50 is stirred, the food at the edge collides with the protrusion 62, which changes the flow direction of the food and improves the mixing effect of the food.

[0036] Please refer to Figure 2 The protrusion 62 is snap-connected with the inner liner 50, and the upper end of the flexible knife cover 60 is threadedly connected with the outer shell 10. Through such a connection method, the flexible knife cover 60 can be quickly installed, and the structural stability of the flexible knife cover 60 after installation is good.

[0037] Furthermore, in other embodiments, the flexible knife cover 60 can also be designed as a fully covering structure, so that the flexible knife cover 60 covers the inner side of the inner liner 50 to provide anti-collision protection for the inner side of the inner liner 50, and the flexible knife cover 60 forms a sealed socket structure with the rotating shaft 20 to prevent liquid from entering the interior of the outer shell 10, thereby improving the sealing performance.

[0038] Please refer to Figure 2 The connecting member 40 includes a sleeve 41 sleeved on the rotating shaft 20, a sleeve 42 sleeved on the outside of the sleeve 41 and a seat 43 sleeved on the outside of the sleeve 42. The upper end of the sleeve 42 cooperates with the outer shell 10, and the upper end of the inner tank 50 is clamped and fixed by the sleeve 42 and the sleeve 41. Through such a connection method, the sleeve 41, the sleeve 42 and the seat 43 can be quickly disassembled and assembled, which is convenient for installation, maintenance or deep cleaning.

[0039] Furthermore, in order to prevent food from entering the inner side of the sleeve 41 through the gap between the sleeve 41 and the rotating shaft 20, a first sealing ring 44 is provided on the inner side of the sleeve 41. The first sealing ring 44 can be made of a material with good elasticity such as silicone. The first sealing ring 44 is sleeved on the rotating shaft 20 and has a good sealing effect.

[0040] Furthermore, in order to prevent food from entering the inner side of the outer shell 10 through the gap between the sleeve 41 and the inner pot 50, a second sealing ring 45 is provided between the sleeve 41 and the inner pot 50. The second sealing ring 45 can be made of a material with good elasticity such as silicone and has a good sealing effect.

[0041] The conventional rotating shaft 20 does not have a buffering function along the axial direction. The stirring blade 30 is prone to get stuck when it collides with harder food. In order to solve this problem, the present embodiment further provides a buffer member 70 in the sleeve 41. The buffer member 70 includes two baffles 71 fixed on the rotating shaft 20 and a core barrel 72 provided between the rotating shaft 20 and the sleeve 41. The rotating shaft 20 can move axially on the core barrel 72. An elastic member 73 is provided between the baffle 71 and the core barrel 72. Under the elastic action of the elastic member 73, the rotating shaft 20 and the stirring blade 30 have a certain buffer space along the axis to prevent the stirring blade 30 from getting stuck.

[0042] In addition, a plurality of notches 51 are provided on the inner pot 50 and the flexible knife cover 60, and liquid food or solid food can enter and exit through the notches 51, which is convenient for mixing or crushing.

[0043] Example 2

[0044] Please refer to Figure 4 The hand-held blender disclosed in this embodiment uses a straight scraper and can be suitable for cylindrical or square containers. The length and size of the straight scraper are not limited and can be designed according to the specific model of the container.

[0045] Example 3

[0046] Please refer to Figure 5 The hand-held blender disclosed in this embodiment adopts a flat scraper with a protruding tip at the bottom, which can be suitable for cylindrical or conical containers. The curvature of the upper end surface and the overall size of the flat scraper are not limited and are designed accordingly according to the specific model of the container.

[0047] The preferred implementation methods of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
