The above arrangement prevents liquid from entering the interior of the drive housing 602 and thus into the power compartment 500 for waterproofing purposes.

The consumable 300 comprises a shell 302 and a buckle joint 702, the buckle joint 702 is arranged at the tail end of the shell 302, an annular table structure is arranged at the tail end of the buckle joint 702, a through middle-through structure which is communicated with the middle of the shell 302 and enables the telescopic rod 301 of the consumable 300 to penetrate is arranged between the buckle joint 702 and the shell 302, and the middle-through structure is coaxial with the shell.

The telescopic rod 301 is sleeved with a spring, one end of the telescopic rod is connected with a transmission device, and the telescopic rod 301 is elastically telescopic in the middle through structure under the cooperation of the transmission device and the spring.

The tail end of the telescopic rod 301 is connected with a transmission bayonet joint, and a transmission guide ring 701 is clamped between the transmission bayonet joint and the annular table structure. The transmission guide ring 701 is a key to ensuring the linear motion in the reciprocating motion of the instrument transmission structure 700, and plays a role in keeping the coaxial motion of the transmission structure 700.

An inner core fastener 703 is sandwiched between the annular table structure and the housing. The core fastener 703 engages the snap joint as a key to limit the travel distance of the snap joint.

As shown in fig. 3, the outer wall surface of the snap joint 702 near the front end of the casing is provided with threads, and the snap joint 702 is screwed with the inner wall surface of the adjusting nut 200. The head end of the telescopic rod 301 is connected with the needle head, the penetration stretches out and draws back in the whole telescopic space of the shell 302, the telescopic space is of a step hole structure, one end of a protective sleeve 303 is sleeved at the needle head shell, and the other end of the protective sleeve is sleeved at the step hole structure, so that liquid is prevented from entering the equipment through a through cavity in the shell.

When a customer uses the instrument, after the instrument is started by pressing the power button 401, the motor 503 starts to rotate under the action of current, so as to drive the transmission head 504 to rotate, and because the transmission head 504 is an inclined plane, when the motor 503 rotates the highest point of the inclined plane of the transmission head 504, the transmission rod 601 can be stably pushed forward for a certain distance under the action of a spring; the transmission bayonet is connected to the transmission lever 601, and the transmission bayonet is connected with the push rod on the consumable 300, so that the product of the physiotherapy consumable 300 can be pushed forward for a certain distance. When the motor 503 drives the transmission head 504 to rotate to the lowest point of the inclined plane, under the action of the elastic force of the spring, the transmission rod 601 drives the transmission bayonet and the physiotherapy consumable 300 connected with the transmission bayonet to move backwards for a certain distance, so that the transmission system is converted from rotary motion to linear reciprocating motion. During the straight reciprocating motion, the skin care essence is slowly introduced into the skin by needling the product of the physiotherapy consumable 300, so that the skin absorption into the essence is better promoted.
