Description

Technical Field

[0001] The embodiments disclosed herein generally relate to mixers. Background Technology

[0002] Blenders are widely used in daily life to pulverize and / or blend food. Blenders are typically equipped with blades to cut and pulverize solids and / or liquids within the blending jar. A lid is fitted to the top of the blending jar to prevent food from splashing out during blending. The blending jar also usually has an airlock to prevent the formation of an overpressure environment inside.

[0003] Existing blenders use air plugs composed of multiple components, resulting in a complex structure. For example, CN 215305235U discloses a spill-proof food processor with a steam hole in the lid, a steam plug within the steam hole, and multiple ventilation channels in the steam plug. CN205903194U discloses a high-speed blender with a feeding hole on the lid. The blender includes a material hole cover that can be placed over the feeding hole, and the material hole cover has ventilation channels. Traditional air plug structures are complex, and there is a desire to further simplify the air plug structure. Summary of the Invention

[0004] Embodiments of this disclosure provide a mixer designed to further simplify the structure of the mixer and thereby reduce its cost.

[0005] According to a first aspect of this disclosure, a mixer is provided. The mixer includes: a base housing a motor; a mixing cup mounted on the base, the mixing cup having mixing blades adapted to be driven by the motor and an opening at its top; and a lid adapted to cover the opening, the lid including a pressure relief device disposed on its top surface, the pressure relief device including a pressure relief orifice allowing communication between the interior of the mixing cup and the environment, the pressure relief device being integrally formed with the lid.

[0006] In some embodiments, the pressure relief device may include a cylindrical body integrally formed with the cup lid and a pair of ribs protruding from the inner wall of the cylindrical body, the inner wall of the cylindrical body defining the pressure relief orifice in a longitudinal direction, and the pair of ribs extending at least partially laterally from opposite inner wall surfaces of the cylindrical body to at least partially block the pressure relief orifice.

[0007] In some embodiments, the pair of ribs may be shaped such that the projection of the pair of ribs in the longitudinal direction completely covers the aperture of the pressure relief orifice.

[0008] In some embodiments, the pair of ribs may be offset from each other by a distance in the longitudinal direction.

[0009] In some embodiments, the pair of ribs may include a first rib and a second rib arranged opposite to the first rib, the first rib including a first edge connected to an inner wall surface and a second edge opposite to the first edge, the second rib including a third edge connected to an inner wall surface and a fourth edge opposite to the third edge, the second edge and the fourth edge being aligned in the longitudinal direction.

[0010] In some embodiments, the first rib and the second rib may be fin-shaped and extend horizontally.

[0011] In some embodiments, the top surface of the cup lid may be partially recessed at the location where the pressure relief device is provided, and the pressure relief device protrudes longitudinally away from the recessed top surface.

[0012] In some embodiments, the top surface of the cup lid may also include a surrounding member that projects longitudinally from the recess, the surrounding member longitudinally surrounding the pressure relief device.

[0013] In some embodiments, the surrounding member may include a bottom edge connected to the recess and a top edge away from the recess, the pressure relief device being connected to the surrounding member at the top edge and disposed within the hollow cavity of the surrounding member.

[0014] In some embodiments, the cup lid and the pressure relief device may be injection molded from plastic.

[0015] According to this disclosure, the pressure relief device is integrally molded with the cup lid, which can significantly reduce the manufacturing cost of the cup lid and prevent the pressure relief device from being lost. Attached Figure Description

[0016] The above and other objects, features, and advantages of embodiments of the present disclosure will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings. Several embodiments of the present disclosure are illustrated in the drawings by way of example and not limitation.

[0021] In the various figures, the same or corresponding reference numerals indicate the same or corresponding parts. Detailed Implementation

[0022] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0023] The term "comprising" and its variations as used herein signify an open-ended inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". Terms such as "upper", "lower", "front", "rear", "lateral", "bottom", etc., indicating placement or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are used only for the purpose of describing the principles of this disclosure, and are not intended to indicate or imply that the elements referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0024] Figure 1 A general schematic diagram of a mixer according to an embodiment of the present disclosure is shown. Figure 2 An exploded view of a mixer according to an embodiment of the present disclosure is shown. Figure 1 and Figure 2 As shown, the mixer 1 includes a base 10, a mixing cup 20, and a lid 30. A motor (not shown) is housed inside the base 10. The housing of the base 10 may be provided with an operation panel 15 for user operation, and the operation panel 15 may be provided with controls for starting the motor, stopping the motor, and / or adjusting the motor. In some embodiments, the controls may be in the form of buttons or knobs; in some embodiments, the controls may be in the form of a touch screen.

[0025] A mixing cup 20 is mounted on a base 10. The mixing cup 20 defines a food mixing chamber, and an opening 22 is provided at the top of the mixing cup 20. Ingredients can be placed into the mixing cup 20 through the opening 22. The blender 1 also includes a mixing unit 25, which includes mixing blades 24. The mixing unit 25 can be coupled to a motor disposed within the base 10. A lid 30 is used to cover the opening 22 to prevent food inside the mixing cup 20 from splashing out through the opening 22 during operation of the blender 1.

[0026] The lid 30 also includes a pressure relief device 40, for example, in the form of a pressure relief hole. This pressure relief hole can communicate with the external environment. During blender 1 operation, the pressure generated inside the blending cup is released via the pressure relief device 40. However, the presence of a pressure relief hole poses a risk that food may splash out of the blending cup during blending. Therefore, the structure of the pressure relief device 40 has a significant impact on the performance of the blender.

[0027] This problem is more pronounced when the blender is a personal blender. Specifically, personal blenders have less headroom compared to standard household blenders, increasing the risk of splattering during blending. For example, a standard household blender has a headroom of 75mm, while a personal blender has only 45mm, significantly less. Here, "headroom" refers to the space above the blending cup 20 when the maximum permissible amount of food is contained within the cup. Considering the limitations of blender portability and storage convenience, the goal is to improve blender performance while minimizing the overall height of the device.

[0028] As described in the background section, conventional pressure relief devices 40 are implemented as air plugs detachable from the lid 30. The air plug may be made of plastic, for example, and is detachably attached to the lid 30. Considering the need to design and manufacture each component independently, and then assemble them together, this detachable structure increases both the manufacturing and maintenance costs of the blender, as the risk of loss of the air plug is high once it is separated from the lid. Loss of the air plug severely impacts the blender's performance. This means the user must either purchase a new air plug or continue using the blender with the defective one, which is undesirable for the user. According to this disclosure, the pressure relief device 40 is integrally molded with the lid 30. In some embodiments, the pressure relief device 40 and the lid 30 are injection molded from plastic. This significantly reduces the manufacturing cost of the lid 30 and prevents the pressure relief device 40 from being lost.

[0029] The following is combined Figure 3 , Figure 4 The structural details of the pressure relief device 40 according to an embodiment of the present disclosure are described in detail. Figure 3 A perspective view of a cup lid as seen from the top side, according to an embodiment of the present disclosure. Figure 4 A cross-sectional schematic diagram of a cup lid according to an embodiment of the present disclosure is shown. Figure 3 , Figure 4 As shown, the pressure relief device 40 may include a cylindrical body 44 integrally formed with the cup lid 30 and a pair of ribs 46a, 46b protruding from the inner wall of the cylindrical body 44.

[0030] In some embodiments, such as Figure 4 As shown, the cylinder 44 may be a substantially hollow structure, with its inner wall defining a longitudinally (i.e., vertically) extending pressure relief port 42. It should be understood that the cylinder 44 here need not be a cylindrical shape. In other embodiments, the cylinder 44 may also be a rectangular cylinder, or a cylinder of other shapes. A pair of ribs 46a, 46b extend at least partially laterally from opposite inner wall surfaces of the cylinder 44 to at least partially block the pressure relief port 42.

[0031] Since ribs 46a and 46b at least partially block the pressure relief hole 42, during the operation of the mixer 1, the liquid splashed from the cavity of the mixing cup will collide with ribs 46a and 46b during the splashing process, so as to at least partially prevent the liquid from splashing out of the mixing cup through the pressure relief hole 42.

[0032] In some embodiments, such as Figure 4 As shown, ribs 46a and 46b extend at least partially laterally from opposite inner wall surfaces of the cylinder 44. In some embodiments, as Figure 4 As shown, ribs 46a and 46b may extend horizontally. In other embodiments, ribs 46a and 46b may extend obliquely.

[0033] In some embodiments, ribs 46a and 46b are fin-shaped. For example, when the pressure relief orifice 42 is a circular orifice, ribs 46a and 46b may be semi-circular fin-shaped. It should be understood that ribs 46a and 46b may be any other suitable shape.

[0034] In some embodiments, such as Figure 4 As shown, a pair of ribs 46a and 46b are shaped such that the longitudinal projection of the pair of ribs 46a and 46b completely covers the aperture of the pressure relief orifice 42. In this case, the pressure relief orifice 42 is completely blocked in the horizontal projection plane to ensure that liquid cannot splash through the pressure relief orifice 42.

[0035] In some embodiments, such as Figure 4 As shown, a pair of ribs 46a and 46b include a first rib 46a and a second rib 46b arranged opposite to the first rib 46a. The first rib 46a includes a first edge 462 connected to the inner wall surface and a second edge 464 opposite to the first edge. The second rib 46b includes a third edge 466 connected to the inner wall surface and a fourth edge 468 opposite to the third edge. The second and fourth edges are aligned longitudinally. In this configuration, it can be ensured that liquid cannot splash through the pressure relief hole 42.

[0036] In some embodiments, a pair of ribs 46a, 46b are longitudinally offset from each other by a distance. This has advantages in terms of using a mold to form the pressure relief device 40. In particular, when the ribs 46a, 46b are shaped such that the longitudinal projection of the pair of ribs 46a, 46b completely covers the aperture of the pressure relief hole 42, the longitudinal offset arrangement of the pair of ribs 46a, 46b facilitates demolding of the pair of ribs 46a, 46b during injection molding.

[0037] In some embodiments, such as Figure 4 As shown, the top surface of the cup lid 30 is partially recessed at the location where the pressure relief device 40 is provided, and the pressure relief device 40 protrudes longitudinally away from the top surface from the recess 32. This reduces the height by which the pressure relief device 40 protrudes from the top surface of the cup lid 30. This is advantageous in miniaturizing the mixer 1.

[0038] In some embodiments, such as Figure 4 As shown, the top surface of the cup lid 30 also includes a surrounding member 34 projecting longitudinally from the recess 32. The surrounding member 34 longitudinally surrounds the pressure relief device 40. The surrounding member 34 can be of various shapes. In some embodiments, such as Figure 3 As shown, the surrounding component 34 can be in the form of a rib. It should be understood that... Figure 3 The illustrated embodiment is merely exemplary, and the surrounding member 34 can be any other suitable shape. By providing the surrounding member 34, effective protection can be provided for the pressure relief device 40, preventing its exposure.

[0039] In some embodiments, such as Figure 4 As shown, the surrounding member 34 includes a bottom edge 342 connected to the recess 32 and a top edge 344 away from the recess 32. The pressure relief device 40 is connected to the surrounding member 34 at the top edge and is arranged in the hollow cavity of the surrounding member 34.

Rather, the specific features and actions described above are merely illustrative examples of implementing the claims.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
