DETAILED DESCRIPTION

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] Reference Figure 1-4 As shown, a homogenizer for preparing food samples comprises a base 1, a motor 2 slidably arranged above the base 1, a cutter head 4 installed on the output end of the motor 2, and a driving rod 3 fixed to the end of the cutter head 4, and a power component for driving the motor 2 to move up and down is arranged on the side of the top surface of the base 1;

[0023] The power component includes a transmission screw 6 that rotates vertically on the top surface of the base 1 and a movable seat 5 that is threadedly connected to the rod of the transmission screw 6. The movable seat 5 is fixedly connected to the outer wall of the motor 2, and telescopic rods 7 are fixed between both ends of the movable seat 5 and the base 1.

[0024] Through the arrangement of the power component, the motor 2, the drive rod 3 and the cutter head 4, when in use, the container containing the material to be processed is placed on the top surface of the base 1 in advance, so that the container corresponds to the cutter head 4, and then the knob transmission screw 6 is turned to prompt the movable seat 5 to slide down along the rod of the transmission screw 6 under the threaded structure. During this process, the motor 2, the drive rod 3 and the cutter head 4 are synchronously displaced in the same direction as the movable seat 5 as a whole until the cutter head 4 penetrates into the container, and then the motor 2 is turned on, and the output end of the motor 2 can drive the drive rod 3 and the cutter head 4, causing the cutter head 4 to stir the material in the container at high speed to achieve a homogenization effect.

[0025] However, in practice, the above embodiment lacks a protective design for the cutter head 4, so that the cutter head 4 is directly exposed to the outside, and when taking or placing a container on the base 1, the cutter head 4 is very likely to scratch a person, which is dangerous.

[0026] For this purpose, refer to Figure 2 and Figure 3 As shown, it is worth noting that it also includes a protective component for hiding the cutter head 4;

[0027] The protection component includes a protective cover 8 sliding on the rod body of the driving rod 3 and a clamping plate 13 fixed to the bottom end of the protective cover 8 in a circular shape. The cutter head 4 is located below the inner side of the protective cover 8 and corresponds to the inner cavity of the clamping plate 13. A reset assembly is provided on the rod body of the driving rod 3.

[0028] By setting the protective component, when the power component is used to drive the rod 3 and the cutter head 4 to be inserted into the container as a whole, the clamping plate 13 in the protective component can contact the container opening in advance, and then when the cutter head 4 is further extended into the container, the clamping plate 13 and the protective cover 8 remain fixed as a whole and slide along the rod body of the driving rod 3, so as not to hinder the entry of the cutter head 4 into the container, and the protective cover 8 can be pressed against the container opening under the elastic force of the reset component to ensure the sealing inside the container and ensure that the material will not splash out when the cutter head 4 is homogenized in the container. On the contrary, when the homogenization process is completed and the cutter head 4 is withdrawn from the container, the protective cover 8 and the clamping plate 13 can be quickly reset as a whole under the elastic force of the reset component to hide the protective cover 8, thereby avoiding being scratched by the protective cover 8 when manually taking and placing the container on the base 1.

[0029] Further, refer to Figure 3 As shown, it is worth noting that the reset assembly includes two fixing plates 9 symmetrically fixed to the rod body of the driving rod 3 and in contact with the inner wall of the top end of the protective cover 8, a guide rod 10 is fixed to the top surface of the fixing plate 9, the end of the guide rod 10 passes through the protective cover 8 and is fixed with a positioning plate 11, and a compression spring 12 is sleeved on the rod body of the guide rod 10 located between the positioning plate 11 and the protective cover 8;

[0030] When the cutter head 4 extends toward the interior of the container, the clamping plate 13 and the protective cover 8 remain fixed as a whole and slide along the shaft of the driving rod 3, the protective cover 8 can simultaneously compress the clamping spring 12, causing the clamping spring 12 to deform. In this way, the elastic force of the clamping spring 12 can be used to make the protective cover 8 close to the container opening to ensure the sealing of the interior of the container. Conversely, when the cutter head 4 withdraws from the interior of the container, the protective cover 8 is quickly reset under the elastic force of the clamping spring 12 to hide the protective cover 8.

[0031] Further, refer to Figure 3 and Figure 4 As shown, it is worth noting that the outer periphery of the clamping plate 13 is sleeved with an increase panel 14, a fixing block 15 is fixed on the inner wall of the increase panel 14, a slot matching the fixing block 15 is opened on the outer wall of the clamping plate 13, a contraction groove 16 is opened on the innermost inner wall of the slot, and a self-locking card is arranged in the contraction groove 16;

[0032] By setting the additional panel 14 and the self-locking clip, the additional panel 14 is mounted on the outside of the clamping plate 13, and the fixing block 15 is aligned and inserted into the slot and fixed by the self-locking clip. In this way, the additional panel 14 can be fixedly installed on the outside of the clamping plate 13, expanding the surface area of ​​the clamping plate 13, so that the clamping plate 13 and the additional panel 14 as a whole can be used to cover containers with larger openings, thereby enhancing the applicability of the device.

[0033] Further, refer to Figure 4 As shown, it is worth noting that the self-locking card includes a positioning block 17 in a right-angle trapezoidal shape and slidably arranged in the contraction groove 16, a fixing groove is opened on the side wall of the fixing block 15, one end of the positioning block 17 is inserted into the fixing groove, and a return spring 18 is fixed between the other end of the positioning block 17 and the innermost inner wall of the contraction groove 16;

[0034] When the fixing block 15 is inserted into the slot, the fixing block 15 can contact the bevel of the positioning block 17 in advance, so that the positioning block 17 is squeezed to shrink toward the inside of the shrinkage groove 16 and squeeze the return spring 18 to deform. In this way, after the fixing block 15 is fully inserted into the slot, the positioning block 17 can be quickly reset under the elastic force of the return spring 18 to penetrate into the fixing groove and lock the fixing block 15.

[0035] Further, refer to Figure 4 As shown, it is worth noting that the outer sliding sleeve of the protective cover 8 is provided with a slide plate 19, a pull rope 20 is fixed on the bottom surface of the slide plate 19, and the end of the pull rope 20 is inserted into the contraction groove 16 and fixedly connected with the positioning block 17;

[0036] By sliding the slide plate 19 upward, the positioning block 17 can be withdrawn from the fixing groove under the pulling force of the pull rope 20, thereby releasing the fixing effect on the fixing block 15 and the added panel 14, and facilitating the removal of the added panel 14.

[0037] Further, refer to Figure 4 As shown, it is worth noting that two pad blocks 21 are symmetrically fixed on the bottom surface of the slide 19;

[0038] By setting the pad block 21, when the sliding of the slide 19 is released, the pad block 21 can prevent the slide 19 from sliding down and directly contacting the surface of the clamping plate 13, so that a certain gap is retained between the clamping plate 13 and the slide 19, thereby facilitating manual lifting of the slide 19 later.
