Description

Split type lower coupler and food preparation machine

Technical Field

The utility model relates to a coupler field, concretely relates to split type lower coupler and food preparation machine.

Background

Along with the improvement of the living standard of people, various small household appliances bring great convenience to consumers, such as a wall breaking machine, a soybean milk machine and the like, and are well loved by the consumers. Taking the wall breaking machine as an example, the wall breaking machine generally comprises a body and a base, wherein an upper coupler (male plug) is arranged on the body, a lower coupler (female plug) and a power socket are arranged on the base, the power socket is used for being externally connected with a power supply, and when the body is placed on the base, the upper coupler on the body and the lower coupler on the base are plugged to form a circuit connection, so that the wall breaking machine is electrified to work; after the food material processing of the wall breaking machine is finished, the body can be taken down from the base so as to be convenient for consumers to use.

Referring specifically to fig. 1 and 1-1, a lower coupler in the prior art is an integrated housing structure, specifically, a jack is provided at the bottom of a housing 1 'to provide a pin, a support 2' is provided at the upper portion of the housing 1', a connection terminal 3' is installed on the support 2', in order to prevent water drops from entering the coupler from the jack to form a circuit fault after the upper coupler is separated from the lower coupler, a waterproof adhesive member 4' is further provided in the lower coupler, and the lower coupler shown in fig. 1 has the following defects: (1) the bottom of the shell is closed (except for the jacks) due to the fact that the shell is of an integrated structure, the waterproof glue piece 4' can only be installed into the assembly cavity 11' of the shell 1' from top to bottom, then the support 2' with wires connected is inserted into the assembly cavity 11', the waterproof glue piece is mainly compressed by the support in the shell in the installation mode, pressing force of the support 2' on the waterproof glue piece 4' is limited, and therefore sealing performance of the waterproof glue piece is poor; (2) in order to improve the sealing performance of the waterproof adhesive piece 4', the waterproof adhesive piece 4' is usually an integral piece and is placed into the assembly cavity 11 'from top to bottom, rather than a waterproof adhesive piece is separately arranged for each jack, so that the assembly cavity 11' of the shell 1 'needs to be designed into a large cavity, the large cavity cannot be divided into a plurality of independent small cavities (otherwise, the waterproof adhesive piece cannot be placed due to the existence of a partition plate), the separation between the wiring terminals 3' is incomplete, the electrical gap and the creepage distance between adjacent wiring terminals are small, and faults are easily caused; (3) as shown in fig. 1 and 1-1, since the assembly chamber 11 'is a large chamber, the bracket 2' has to use an integral structure, that is, a plurality of terminals are simultaneously mounted on one bracket, when a pipeline worker performs wiring, a person is required to simultaneously connect a plurality of lines (6 lines shown in fig. 1), which is easy to connect wrong lines, so that the line sequence of the lines and the terminals is wrong (for example, a red line should be connected to the terminal 1, but the worker may mistakenly connect the red line to the terminal 2), and finally the defective rate of the lower coupler increases; moreover, if the work time needs to be returned due to the wrong wire sequence, a worker needs to take out the whole support, and the wrong wire is detached from the wiring terminal and then is reconnected, so that the operation is troublesome, and the overhaul is difficult.

For this reason, there is a need for improvements and optimizations to existing lower coupler structures.
