DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In the related art, there is a problem that the crushing effect of the juicer is poor.

[0025] In view of this, the present application embodiment proposes a tool assembly 10, such as Figure 1-4 As shown, the tool assembly 10 includes a fixing member 101, a first blade 102, a second blade 103 and a third blade 104. The fixing member 101 is a columnar structure that provides mounting support for the first blade 102, the second blade 103 and the third blade 104. The two ends of the fixing member 101 are respectively a first end and a second end. The first end and the second end refer to the opposite ends of the fixing member 101. Figure 1 , which are the upper and lower ends of the fixing member 101. The first blade 102 includes a first mounting portion 1021, a first side portion 1022, and a second side portion 1023. The first mounting portion 1021 has a central opening, and the first mounting portion 1021 is sleeved on the fixing member 101 through the hole. The first side portion 1022 and the second side portion 1023 are respectively connected to the two sides of the first mounting portion 1021. The first side portion 1022 extends obliquely from the first mounting portion 1021 in a direction away from the first end. A first inclination angle is formed between the first side portion 1022 and the first mounting portion 1021, which is α in the figure. A second inclination angle is formed between the second side portion 1023 and the first mounting portion 1021, which is β in the figure. The size of the first inclination angle is not fixed. Preferably, the first inclination angle is 15 to 30 degrees. In the present embodiment, the first inclination angle is preferably 15 degrees. The size of the second inclination angle is not fixed. Preferably, the second inclination angle is 45 to 90 degrees. In the present embodiment, the second inclination angle is preferably 85 degrees. In terms of technology, the first inclination angle and the second inclination angle are both bending angles, which are formed after a bending process. The first inclination angle and the second inclination angle are different in angles. Compared with the existing symmetrical blades, the turbulence area formed by the symmetrical blades is concentrated and confined to the middle part, and the crushing effect and wall breaking effect on the middle food are poor, and residues are easily formed. Since the first inclination angle and the second inclination angle are different in angles, the food residues after preliminary crushing will not gather in the middle position, but will be led to both ends by the eddy current, so that the food residues are fully crushed and the crushing effect and wall breaking effect are improved.

[0026] Please continue reading Figure 1In the figure, the second blade 103 is obliquely extended from the fixing member 101 along the direction away from the second end. Specifically, the second blade 103 includes a second mounting portion 1031, a third side portion 1032 and a fourth side portion 1033. The second blade 103 is sleeved on the fixing member 101 through the second mounting portion 1031, and the third side portion 1032 and the fourth side portion 1033 are respectively connected to both sides of the second mounting portion 1031. The third side portion 1032 and the fourth side portion 1033 are symmetrical about the fixing member 101. There is a gap between the third side portion 1032 and the fourth side portion 1033 and the second mounting portion 1031. The angle is preferably 45 degrees in the present embodiment. When the second blade 103 rotates forward or reversely, the food can be stirred from the bottom, so that the first blade 102 and the third blade 104 can better cut the food forward and reversely. From the axial direction of the fixing part 101, the extension directions of the first blade 102 and the second blade 103 are opposite. The food residues after cutting by the third blade 104 will be drained to both ends by the vortex formed by the first blade 102 and the second blade 103, which effectively avoids the food residues after the initial crushing from being concentrated in the middle position, thereby improving the crushing effect and the wall breaking effect.

[0027] Please continue reading Figure 1 The third blade 104 includes a third mounting portion 1041 , a toothed portion 1042 and an arc-shaped portion 1043 . The third blade 104 is sleeved on the fixing member 101 through the third mounting portion 1041, the toothed portion 1042 is smoothly connected to the third mounting portion 1041, and the arc portion 1043 is smoothly connected to the end of the toothed portion 1042 away from the fixing member 101. In fact, the toothed portion 1042 is closer to the fixing member 101 than the arc portion 1043. When the tool assembly 10 is working, the fixing member 101 is connected to the motor transmission, and the third blade 104 will make a circular motion around the fixing member 101. It can be seen from the linear velocity formula that V=W*R, W is the angular velocity, and R is the rotation radius. It can be seen that the linear velocity at the toothed portion 1042 is greater than the linear velocity of the arc portion 1043. Therefore, the toothed portion 1042 can specifically crush larger food, while smaller food residues are specifically crushed and broken by the arc portion 1043.

[0028] Furthermore, there is a certain angle between the arc-shaped portion 1043 and the tooth-shaped portion 1042. In the present embodiment, the angle is preferably 90 degrees, so that relatively large and relatively hard food can be crushed and cut when the third blade 104 rotates forward or reversely.

[0029] Furthermore, the width of the arc portion 1043 gradually decreases from the tooth-shaped portion 1042 in the direction away from the fixing member 101. It can be seen from the figure that the end of the arc portion 1043 is pointed, and the edges of the arc portion 1043 are all sharpened. The edges of the arc portion 1043 can cut food, and the arc design can also avoid stress concentration during cutting.

[0030] Furthermore, the first blade 102, the second blade 103 and the third blade 104 are arranged at intervals along the circumference of the fixing member 101. The intervals between the first blade 102, the second blade 103 and the third blade 104 can guide the food to different areas while the surfaces of the first blade 102, the second blade 103 and the third blade 104 can all contact the surface of the food. Compared with an overlapping blade combination, the contact area can be effectively increased, thereby improving the crushing and wall-breaking effects of the food.

[0031] When the juicer is in use, if the food is not broken up, the blade may get stuck due to the large size of the food.

[0032] To address this problem, an embodiment of the present application further provides a forward and reverse rotation device, which can solve the problem of the blade getting stuck when the food is not broken.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the forward and reverse rotation device includes a power member 4, a tool assembly 10 described in any one of the above items, and a controller 2. The power member 4 is a motor, which can rotate forward and reverse, and the type of the motor is not fixed. The power member 4 is connected to the tool assembly 10 described in any one of the above items in a transmission manner. In fact, in this embodiment, the fixed member 101 in the tool assembly 10 is connected to the power member 4 in a transmission manner, and the fixed member 101 drives the first blade 102, the second blade 103 and the third blade 104 to move. The controller 2 is electrically connected to the power member 4, and the controller 2 has a built-in control circuit, which controls the power member 4 to rotate forward and reverse. For example, when food is placed in the juicer, at the beginning, the resistance encountered by the tool assembly 10 is less than the set value, the power piece 4 rotates forward, and the tool assembly 10 rotates forward accordingly. When the tool assembly 10 is stuck by food, the resistance encountered by the tool assembly 10 is greater than the set value, and the control circuit controls the power piece 4 to reverse, at which time the tool assembly 10 also reverses accordingly. If the resistance encountered by the tool assembly 10 during both forward and reverse rotations is greater than the set value, the tool assembly 10 is stuck both forward and reverse, and at this time the control circuit controls the power piece 4 to stop working to prevent damage to the power piece 4 and the tool assembly 10.

[0034] It should be supplemented that the setting of the first inclination angle and the second inclination angle enables the first side portion 1022 and the second side portion 1023 to bevel the food when the power member 4 rotates forward and reversely, so that the food can be chopped more quickly.

[0035] like Figure 1-4 As shown, an embodiment of the present application further provides a juicer, which includes the above-mentioned housing 3 and the above-mentioned forward and reverse rotation device arranged in the housing 3.

[0036] As can be seen from the figure, a charging port 322 is provided on the outer surface of the housing 3. The housing 3 includes a base 31, a bottom shell 33 and a housing body 32. The base 31 is located at the top of the housing 3 and is used to fix one end of the power part 4 (i.e., the motor). A waterproof ring 16 is embedded on the inner surface of the base 31. The waterproof ring 16 is attached to the upper surface of the forward and reverse rotation device to prevent the leakage of food juice in the juicer. Figure 1-4 The first blade 102, the second blade 103 and the third blade 104 are fixed to the fixing member 101 by screws 105. The outer surface of the shell body 32 is provided with a button hole 321 and a charging port 322. The button 17 is adapted to the button hole 321. The button 17 is electrically connected to the controller 2 for manually controlling the direction and speed of the forward and reverse device. The shading sponge 9 is used to block sunlight. The shape of the shading sponge 9 is adapted to the shape of the button hole 321 and is arranged at the button hole 321. The charging port 322 is located below the button 17. The type of the charging port 322 is not fixed and can be a USB, Type-C interface, etc. The button cap 12 and the button sub-plate 11 are arranged in the shell body 32.

[0037] The juicer also includes a motor bracket 6, which provides support for the power part 4. The motor plug 18 fixes the power part 4 to the motor bracket 6, and the motor bracket 6 is fixed to the bottom shell 33. The bottom of the bottom shell 33 is affixed with dust-proof silicone 7. Furthermore, the juicer also includes a light guide ring 14 and a light ring 13. The light ring 13 is electrically connected to the controller 2. The light ring 13 is embedded in the light guide ring 14. The light guide ring 14 is clamped in the shell 3 to indicate the working status of the juicer. The light guide ring 14 is clamped on the bottom shell 33.

[0038] The juicer further includes a bottom cover 19, which is disposed at the bottom of the bottom shell 33. The anti-skid pad 15 is attached to the bottom cover 19 by adhesive to provide a stable working state for the motor when it is working.

[0039] In addition, the juice extractor further comprises a battery 5 , which provides power for the entire juice extractor and is stored in the housing body 32 .

[0040] It should be noted that the control circuit for the forward and reverse rotation of the tool assembly 10 and the circuit for the light ring 13 to display the state change involved in the controller 2 in the present application are conventional technical means and will not be described in detail here.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0042] It should also be noted that, in this article, the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations, nor can they be understood as indicating or implying relative importance.
