Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a miniaturized food processing machine. Background Art

[0002] When the food processor adopts a separate main unit and cup body, the cup body is provided with an upper coupler and the main unit is provided with a lower coupler. After the cup body is placed in place, the electrical connection between the cup body and the main unit can be achieved through plug-in coupling of the upper and lower couplers.

[0003] In order to meet the requirements of safety distance, the routing of the existing lower coupler's plug spring is mostly parallel to the coupling stroke direction, which results in the lower coupler height being increased to meet the national standard requirements of creepage distance, resulting in the axial height of the whole machine being increased, affecting the shape of the whole machine and increasing costs.

[0004] In order to achieve compression of the axial space of the main machine, patent CN219613707U discloses a food processing machine, which reduces the overall height of the lower coupler assembly and the motor combination by reducing the distance between the bottom surface of the lower coupler and the top surface of the motor, and at the same time, the wiring harness assembly that cooperates with the lower coupler plug spring is led out from the plug spring bracket and then bent to the side of the lower coupler assembly through the bending part and led out to the side of the lower coupler assembly.

[0005] Although the above scheme can reduce the height of the whole machine to a certain extent, the wiring harness connected to the plug spring passes through the bottom of the plug spring bracket and then bends to the side, which is still not conducive to further compression of the height of the lower coupler assembly. In addition, there is a section of the wiring harness parallel to the extension direction of the plug spring. The wiring harness is likely to produce a pulling force on the spring leaf of the plug spring. During the operation of the machine, under the influence of the high-frequency vibration impact of the motor, the plug spring is easily affected by the external force caused by the pulling of the wiring harness, which will increase the risk of spring leaf breakage. The consequence is failure of the upper and lower electrical coupling and loss of function of the whole machine, thus reducing the reliability and life of the product. Utility Model Content

[0006] In order to solve the technical problems in the prior art that the overall height of the lower coupler assembly is relatively high, which is not conducive to the compression of the axial height of the whole machine, and the plug spring is easily pulled by the wire harness connected to it, which increases the risk of spring breakage, the utility model provides a miniaturized food processing machine.

[0011] A limiting member is provided at the bottom of the accommodating groove, which is used to limit the travel of the first spring piece in the lateral direction when it is installed into the accommodating groove.

[0012] The limiting member includes a stopper extending along the width direction of the accommodating groove and a limiter vertically connected to the stopper.

[0013] An installation gap is provided between the limiting block and the bottom wall of the containing groove, and the bottom wall of the first spring sheet is interference-fitted with the installation gap.

[0014] The bottom of the accommodating groove is provided with a boss protruding outward toward one side of the opening, and the lower end of the lower coupler shell is provided with a notch to avoid the boss.

[0018] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0019] 1. The miniaturized food processing machine of the utility model has a side-outlet wiring harness, which does not need to be bent, and can reduce the overall height of the lower coupler, thereby reducing the assembly height of the entire machine, making the center of gravity of the entire machine lower and more stable; the wiring harness is perpendicular to the coupling direction, that is, the wiring harness is perpendicular to the extension direction of the spring sheet that cooperates with the plug pin, and the plug spring is not easily affected by the external force of the wiring harness pulling, thereby preventing the plug spring spring sheet from breaking, and improving the reliability of the electrical coupling of the upper and lower couplers. In addition, the plug spring is inserted horizontally through the side opening, which is more convenient, and compared with vertical insertion, it can better ensure that multiple plug springs are at the same height, which can avoid the inconsistent heights of multiple plug springs causing poor contact between the upper and lower couplers, and further improve the reliability of electrical coupling.

[0020] 2. As a preferred embodiment, the plug spring includes a first spring piece that cooperates with the pin of the upper coupler and a second spring piece for fixing the wire harness, the second spring piece is connected to the bottom side of the first spring piece, and one end of the wire harness is wrapped inside the second spring piece. By arranging the second spring piece laterally to the first spring piece, conditions are provided for the side outlet of the wire harness, and the second spring piece wraps the wire harness to ensure the reliability of the wire harness connection, and the second spring piece provides a certain support for the wire harness, which can prevent the wire harness from sagging and pulling the first spring piece, increasing the risk of the first spring piece breaking.

[0021] As a preferred embodiment of the present embodiment, the second spring piece includes two second sub-spring pieces arranged opposite to each other and a supporting spring piece connecting the two second sub-spring pieces, and the wiring harness is supported by the supporting spring piece and clamped by the two second sub-spring pieces. By bearing the weight of the wiring harness by the supporting spring piece, the wiring harness can be prevented from generating a force pulling the first spring piece to increase the risk of the first spring piece breaking, and at the same time, the wiring harness is clamped by the two second sub-spring pieces, which can improve the firmness and reliability of the wiring harness connection.

[0022] 3. As a preferred embodiment, a limiter is provided at the bottom of the receiving groove to limit the travel of the first spring piece in the transverse direction when it is inserted into the receiving groove. Therefore, when installing the spring, the first spring piece is abutted against the limiter to determine the horizontal travel of the first spring piece, providing a feel that the first spring piece is installed in place, ensuring the accurate installation position of the first spring piece, and also facilitating improving installation efficiency.

[0023] Furthermore, the limiting member includes a stopper extending along the width direction of the receiving groove and a limiter connected vertically to the stopper, and the first spring piece is installed in place when the end of the first spring piece toward the stopper abuts against the stopper, and the limiter is inserted into the inner side of the first spring piece to limit the movement of the first spring piece along the width direction of the receiving groove. After the insertion spring is installed in place, the stopper and the limiter form a limit for the first spring piece in three directions, which improves the stability of the position of the first spring piece, and can ensure the effective insertion of the upper and lower couplers, thereby ensuring the normal operation of the machine.

[0024] Furthermore, an installation gap is provided between the limit block and the bottom wall of the receiving groove, and the bottom wall of the first spring piece is interference-fitted with the installation gap. The bottom wall of the first spring piece is interference-fitted with the installation gap, which limits the movement of the first spring piece in the vertical direction, and can prevent the first spring piece from moving up and down when the upper coupler is plugged in and out, causing its position to be unstable and affecting the plugging effect with the upper coupler, and further ensures the effective plugging of the upper and lower couplers.

[0025] 4.

When the lower coupler housing is covered on the outside of the lower coupler bracket, the lower coupler housing closes the opening and the notch is snapped onto the top of the boss. The lower coupler housing closes the opening so that the plug spring is located in the closed cavity, which has a waterproof effect. The notch can avoid the wiring harness, making the lower coupler housing cover more smooth. After the lower coupler housing is covered, the outer wall of the lower coupler housing is flush with the outer end face of the boss, which can improve the aesthetics.

[0026] 5. As a preferred embodiment, the lower coupler further comprises a sealing member covered on the top of the lower coupler housing, and the sealing member is provided with a plug hole corresponding to the receiving groove for the insertion of the pin of the upper coupler. By providing the sealing member, when the upper coupler is not inserted, the plug hole is naturally closed under the action of elasticity, which can prevent water from entering and improve the safety of use.

[0027] 6. As a preferred embodiment, two mounting holes are provided on two opposite side walls of the lower coupler housing for plugging and mating with the mounting posts on the host bracket, and the diameters of the two mounting holes are not equal. The two mounting holes are provided with different sizes to form a foolproof design, which can prevent the lower coupler from being installed in the wrong direction and affecting the electrical coupling.

[0045] like Figures 1 to 6 As shown, the present application provides a miniaturized food processing machine, including a main machine and a cup body installed on the main machine, an upper coupler is provided at the bottom of the cup body, a lower coupler 10 coupled with the upper coupler is provided on the top of the main machine, the lower coupler 10 includes a lower coupler bracket 11, a lower coupler shell 12 covered on the outside of the lower coupler bracket 11, a plug spring 13 installed inside the lower coupler bracket 11 and a wiring harness 14 connected to the plug spring 13, the lower coupler bracket 11 is provided with a receiving groove 111 extending along the coupling direction, the receiving groove 111 is laterally provided with an opening 112, the plug spring 13 is transversely installed in the receiving groove 111 through the opening 112, the wiring harness 14 is located on the outside of the opening 112 and the wiring harness 14 is arranged perpendicular to the coupling direction.

[0046] In the miniaturized food processing machine of the present application, the wiring harness 14 is a side outlet, and the wiring harness 14 does not need to be bent, which can reduce the overall height of the lower coupler 10, thereby reducing the assembly height of the whole machine, making the center of gravity of the whole machine lower and more stable; because the wiring harness 14 is perpendicular to the coupling direction, that is, the wiring harness 14 is perpendicular to the extension direction of the spring sheet that cooperates with the pin, the plug spring 13 is not easily affected by the external force pulled by the wiring harness 14, thereby preventing the spring sheet of the plug spring 13 from breaking, and improving the reliability of the electrical coupling between the upper and lower couplers. In addition, the plug spring 13 is inserted horizontally through the side opening 112, which is more convenient, and compared with vertical insertion, it can better ensure that multiple plug springs 13 are at the same height, which can avoid the inconsistent heights of multiple plug springs 13 causing poor contact between the upper and lower couplers, and further improve the reliability of electrical coupling.

[0047] like Figure 2 and Figure 3 As shown, the lower coupler bracket 11 is provided with a vertically extending accommodating groove 111, the coupling direction is parallel to the extending direction of the accommodating groove 111, the coupling direction is the plug-in direction of the upper coupler, and the upper coupler is plugged and unplugged along the vertical direction to cooperate with the lower coupler 10. The wire harness 14 of the present application extends horizontally without bending. Compared with the prior art in which the wire harness 14 vertically passes through the bottom of the lower coupler bracket 11 and then bends, the overall height of the lower coupler 10 of the present application is further compressed, which is conducive to the axial miniaturization of the entire machine.

[0048] Two adjacent accommodating grooves 111 are arranged to be separated from each other, and a single accommodating groove 111 has only a lateral opening 112 and an open top. After the plug spring 13 is installed in place, the lower coupler housing 12 is installed on the outer side of the lower coupler bracket 11, and a sealing member 16 is provided on the top of the lower coupler housing 12 to place the plug spring 13 in a closed cavity, which has good waterproof performance.

[0049] As a preferred embodiment, the plug spring 13 includes a first spring leaf 131 that cooperates with the pin of the upper coupler and a second spring leaf 132 for fixing the wiring harness 14. The second spring leaf 132 is connected to the bottom side of the first spring leaf 131, and one end of the wiring harness 14 is wrapped around the inner side of the second spring leaf 132.

[0050] like Figure 2 , Figure 4 or Figure 5 As shown, by arranging the second reed 132 laterally on the first reed 131, conditions are provided for the side outlet of the wire harness 14, and the second reed 132 wraps the wire harness 14 to ensure the reliability of the connection of the wire harness 14, and the second reed 132 provides a certain support for the wire harness 14, which can prevent the wire harness 14 from sagging and pulling the first reed 131, increasing the risk of the first reed 131 breaking.

[0051] As a preferred embodiment of the present embodiment, the second spring piece 132 includes two second sub-spring pieces 1321 arranged opposite to each other and a support spring piece 1322 connecting the two second sub-spring pieces 1321. The wire harness 14 is supported by the support spring piece 1322 and clamped by the two second sub-spring pieces 1321. The weight of the wire harness 14 is carried by the support spring piece 1322, so that the wire harness 14 is prevented from generating a force that pulls the first spring piece 131 and increases the risk of the first spring piece 131 breaking. At the same time, the wire harness 14 is clamped by the two second sub-spring pieces 1321, so that the firmness and reliability of the connection of the wire harness 14 can be improved.

[0052] It can be understood that the second spring leaf 132 is provided with at least one group. In order to improve the supporting effect of the wire harness 14, in a preferred example, the second spring leaf 132 is provided with multiple groups, and the multiple groups of second spring leaves 132 are arranged at intervals along the extension direction of the wire harness 14, such as Figure 2 A solution with two groups of second reeds 132 is shown.

[0053] As a preferred embodiment, a limiting member 15 is provided at the bottom of the receiving groove 111 to limit the travel of the first spring piece 131 in the lateral direction when it is inserted into the receiving groove 111. Therefore, when the insertion spring 13 is installed, the first spring piece 131 is abutted against the limiting member 15 to determine the horizontal travel of the first spring piece 131, providing a feel that the first spring piece 131 is installed in place, ensuring that the first spring piece 131 is installed in an accurate position, and also facilitating improving the installation efficiency.

[0054] Furthermore, the limiting member 15 includes a stopper 151 extending along the width direction of the accommodating groove 111 and a limiter 152 vertically connected to the stopper 151. When the end of the first spring leaf 131 toward the stopper 151 abuts against the stopper 151, the first spring leaf 131 is installed in place, and the limiter 152 is inserted into the inner side of the first spring leaf 131 to limit the movement of the first spring leaf 131 along the width direction of the accommodating groove 111.

[0055] like Figure 2 , Figure 4 and Figure 6 As shown, the limiting member 15 is T-shaped, the first spring leaf 131 is approximately U-shaped, the bottom of the limiting block 152 is higher than the bottom wall of the accommodating groove 111, and when the first spring leaf 131 moves inward through the opening 112, the bottom wall of the first spring leaf 131 moves below the bottom of the limiting block 152. After the plug spring 13 is installed in place, the stopper 151 and the limiting block 152 form limits on the first spring leaf 131 in three directions, which improves the stability of the position of the first spring leaf 131, and can ensure the effective insertion of the upper and lower couplers, thereby ensuring the normal operation of the machine.

[0056] Furthermore, an installation gap 153 is provided between the limit block 152 and the bottom wall of the receiving groove 111, and the bottom wall of the first spring leaf 131 is interference-fitted with the installation gap 153. Figure 4 As shown, the bottom wall of the first spring piece 131 is interference-fitted with the installation gap 153, which limits the movement of the first spring piece 131 in the vertical direction. This can prevent the first spring piece 131 from moving up and down when the upper coupler is plugged in or out, causing its position to be unstable and affecting the plug-in effect with the upper coupler, further ensuring the effective plug-in of the upper and lower couplers.

[0057] As a preferred embodiment, the bottom of the accommodating groove 111 is provided with a boss 113 protruding outward toward the side of the opening 112, and the lower end of the lower coupler shell 12 is provided with a notch 121 for avoiding the boss 113. When the lower coupler shell 12 is covered on the outside of the lower coupler bracket 11, the lower coupler shell 12 closes the opening 112 and the notch 121 is snapped onto the top of the boss 113.

[0058] By closing the opening 112 of the lower coupler shell 12, the plug spring 13 can be located in the closed cavity, which has a waterproof effect. The notch 121 can avoid the wiring harness 14, making the installation of the lower coupler shell 12 smoother. After the lower coupler shell 12 is installed, the outer side wall of the lower coupler shell 12 is flush with the outer end surface of the boss 113, which can improve the aesthetics.

[0059] like Figure 2 , Figure 5 and Figure 6 As shown, the lower coupler bracket 11 is provided with a buckle 114 on the outer wall between the two bosses 113, and the lower coupler housing 12 is correspondingly provided with a slot 122, and the reliability of assembly can be improved by the cooperation between the buckle 114 and the slot 122.

[0060] As a preferred embodiment, the lower coupler 10 further comprises a sealing member 16 which is covered on the top of the lower coupler housing 12 , and the sealing member 16 is provided with a plug hole corresponding to the receiving groove 111 for the insertion of the pin of the upper coupler.

[0061] like Figure 2As shown, by providing the sealing member 16, when the upper coupler is not inserted, the jack is naturally closed under the action of elasticity, which can prevent water from entering and improve the safety of use. The jack is, for example, a common straight-shaped jack, a cross-shaped jack, etc., which has a good self-sealing effect.

[0062] As a preferred embodiment, two mounting holes 17 are provided on two opposite side walls of the lower coupler housing 12 for mating with the mounting posts on the host bracket, and the diameters of the two mounting holes 17 are not equal. Figure 2 As shown, the two mounting holes 17 are set in different sizes to form a fool-proof design, which can prevent the lower coupler 10 from being installed in the wrong direction and affecting the electrical coupling.

[0063] As a preferred implementation, a motor 18 is provided in the main machine, the lower coupler 10 is provided above the motor 18 , and the horizontal projection of the lower coupler 10 falls within the horizontal projection range of the motor 18 .

[0064] like Figure 1 As shown, in some embodiments, by making the horizontal projection of the lower coupler 10 fall within the horizontal projection range of the motor 18, the radial volume of the host can be reduced, which is conducive to the miniaturization of the host. Of course, in other embodiments, the lower coupler 10 and the motor 18 can also partially overlap in the radial direction, which is still conducive to reducing the radial volume of the host compared to arranging the two in parallel in the horizontal direction.

[0065] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
