Abstract:
1. A skin-stimulation unit, comprising: a striking member configured to exert impact on skin by reciprocating in a linear manner, the striking member comprising a hollow portion; a cap part into which the striking member is slidably inserted; a connecting rod, connected at a front end of the connecting rod to the striking member and connected at a rear end of the connecting rod to an external power source, to reciprocate the striking member in a linear manner; and a connector between the striking member and the connecting rod configured to separably connect the striking member and the connecting rod, wherein a front end of the connector is inserted into the hollow portion of the striking member which maintains an airtight state between the connector and the striking member and the front end of the connector is removably snap-engaged with a connecting hole of the striking member, wherein the striking member comprises a plurality of protrusions formed on a front end of the striking member to stimulate the skin, wherein the striking member is formed from elastic material, wherein each of the plurality of protrusions comprises a hollow portion to buffer impact when the front end of the striking member strikes the skin, wherein the connector comprises a projecting part which is formed adjacent to the front end of the connector, and wherein a rear end of the connecting hole of the striking member is coupled to a groove formed between the front end of the connector and the projecting part so that when the striking member strikes the skin the rear end of the connecting hole of the striking member is supported by the projecting part to maintain the hollow portion.
