Description

Technical Field

[0001] This utility model relates to a hair clipper and shaving machine, and more particularly to a multifunctional hair removal device structure. Background Technology

[0002] The market offers a wide variety of hair-cutting, shaving, and beard-shaving products. One type is the bald head shaver, which, as the name suggests, provides deep hair removal. However, this type of product has relatively few applications and its functions are quite limited. Furthermore, most of the aforementioned bald head shavers have a disc-shaped contact cutting surface, making it difficult to thoroughly clean specific areas or hard-to-reach corners. There is a lack of a multi-functional product that can meet the needs of various usage scenarios, thereby increasing product utilization and relatively reducing operating costs. Utility Model Content

[0016] Figure 2 This is an exploded structural diagram of the present invention;

[0017] Figure 3 This is a schematic diagram of the transmission structure of this utility model. Detailed Implementation

[0018] like Figures 1-3 As shown, a multifunctional hair removal device structure includes a base 1. The lower part of the base 1 has a lower blade head 2 for shaving human hair, and the upper part of the base 1 has an upper blade head 3 for shaving human hair. The bottom of the upper blade head 3 has a connecting part 4 connecting to the base 1. The base 1 has a connecting component 5 corresponding to the connecting part 4, and an eccentric transmission component 6 is provided between the connecting part 4 and the base 1. The base 1 contains an upper motor that is linked to the eccentric transmission component 6 and a lower motor that connects to the lower blade head 2. In this embodiment, the lower blade head 2 is used for smooth haircutting, but this is not its only limitation. The upper blade head 3 is a razor or electric hair clipper head. The connecting part 4 and the connecting component 5 are designed to facilitate the replacement of different haircutting and shaving heads, and the eccentric transmission component 6 improves transmission efficiency. This embodiment uses a dual-blade design to meet the needs of large-area and localized haircutting or shaving, and different blade heads can be replaced as needed.

[0019] The base 1 is composed of an upper shell 7, a middle shell 8, and a lower shell 9. An upper and lower interlayer are formed between the upper shell 7 and the middle shell 8, and between the middle shell 8 and the lower shell 9, respectively. The upper motor is located in the upper interlayer, and the lower motor is located in the lower interlayer. This interlayer design facilitates full utilization of space and ensures structural strength, while also isolating interference and component operation conflicts. The connecting part 4 has abutment surfaces 10 on opposite sides, and a positioning groove 11 on the side adjacent to the abutment surfaces 10. The connecting assembly 5 includes a positioning seat 12, which has a mating groove 13 with an opening in its top wall. The positioning groove 11 has a positioning protrusion 15 that engages with the mating groove 13. The opening of the mating groove 13 allows the positioning protrusion 15 to engage; other forms of engagement, such as blocking and limiting, are also possible but will not be elaborated upon or limited here. The abutment surface 10 ensures a stable installation of the connecting part 4, and the cooperation between the mating groove 13 and the positioning protrusion 15 further guarantees a secure connection. The split installation structure of the base 1 facilitates disassembly and assembly, and can also reduce the failure rate or increase service life. The abutment surface 10 is provided with a positioning strip 16, and the mating groove 13 is provided with a slot 17 for the positioning strip 16 to be inserted. The design of the positioning strip 16 further strengthens the positioning connection on adjacent surfaces, complementing the location of the positioning protrusion 15.

[0020] The eccentric transmission assembly 6 includes an eccentric seat 18, a linkage seat 19, a connecting seat 22, and an eccentric shaft 23 arranged sequentially along the same axis. The eccentric seat 18 has a connecting groove 13 on its upper part, and the linkage seat 19 has a connecting block 14 corresponding to the size and shape of the connecting groove 13 on its lower part. The connecting groove 13 and the connecting block 14 are engaged in a circumferential linkage. The design of the connecting block 14 and the connecting groove 13 is generally triangular, suitable for torsional transmission, eliminating the need for keyways or other structures, thus meeting design requirements, but this is not the only limitation. The lower part of the eccentric seat 18 also has a sleeve directly connected to the motor output shaft; the specific connection method varies, and here the sleeve is offset relative to the axis of the eccentric seat 18. The connecting seat 22 and the linkage seat 19 are axially engaged, and their circumferential rotational engagement is firm and reliable. The eccentric shaft 23 corresponds to the eccentric seat 18, and the eccentric design ensures reliable and smooth transmission and a relatively tight connection.

[0021] The upper part of the linkage seat 19 is provided with a protrusion 20, and the lower part of the connecting seat 22 is provided with a slot 21 for the axial insertion of the protrusion 20. This is one type of snap-fit ​​connection, not the only one, which facilitates disassembly and replacement. The eccentric shaft 23 includes a concentric part 24 at the lower part and an eccentric part 25 at the upper part, which is somewhat similar to the design of the eccentric seat 18. The eccentric part 25 continues to transmit power through plug-in or other connection methods, which will not be elaborated or limited here. The positioning seat 12 is provided with a groove 26 on the relatively outer side that connects to the inner side. A spring 27 is provided at the groove 26. The installation of the spring 27 here gives the positioning seat 12 a certain elastic force, which is used to reduce shock and enhance the contact, and also helps to clamp and assist in the positioning of the central mounting component of the positioning seat 12. The grooves 26 are arranged in pairs on both sides of the positioning seat 12, and the spring 27 has a U-shaped structure.
