Description

Technical Field

[0001] The present application relates to the technical field of electric shavers, and in particular to a floating shaver head. Background Art

[0002] Electric shavers are cosmetic appliances that use electricity to drive blades to shave beards and sideburns. Electric shavers are divided into two types according to the blade action mode: rotary and reciprocating. The former has a simple structure, low noise, and moderate shaving force; the latter has a complex structure, high noise, but high shaving force and high sharpness.

[0003] In order to better fit the user's face, the existing electric shaver is designed to have a floating part where the blade head is located. Relevant prior art, such as the Chinese patent application "Razor Floating Blade Head", application number: CN201210339806.4; discloses an outer blade holder, an outer blade mesh frame, an outer blade assembly, an inner blade assembly, an inner blade bracket, a floating support frame, a floating support frame and a driving connection device; the inner blade assembly is placed on the inner blade bracket; the outer blade assembly is placed outside the inner blade assembly; the outer blade mesh frame is placed outside the outer blade assembly and is clamped with the inner blade bracket; the inner blade bracket is installed on the outer blade holder and rotates; the floating support frame is movably matched with the inner blade bracket; the floating support frame is plugged with the floating support frame, and the upper end of the floating support frame is in contact with the inner blade bracket; the driving connection device is plugged with the inner blade assembly and rotates. The floating blade head of the razor in the above patent application has a simple structure, and its floating structural characteristics make the blade head close to the face, which can reduce the number of times the razor head moves in the same part, greatly improve the shaving efficiency, and is comfortable and convenient to use.

[0004] Another example is the Chinese patent application "A floating blade net structure for a razor", application number: CN202111261333.6; it discloses a blade net, a blade net frame, a head cover, a spring piece and a positioning frame, wherein the blade net frame is installed on the head cover, the blade net is installed in the blade net frame, the spring piece is installed in cooperation with the head cover and floatingly supports the blade net, and the positioning frame and the head cover are connected by a rotating buckle to limit and fix the spring piece. The present invention also provides a razor, including the above-mentioned floating blade net structure for a razor. The above-mentioned patent application directly adopts a spring piece to floatingly support the blade net, and then uses a positioning frame to limit and fix the spring piece, and directly connects it with the head cover through a rotating buckle, thereby eliminating the support ring and the knob, reducing the number of parts, and reducing labor costs and mold costs; the present invention has simple structural features, and has good floating effect and better veneer effect under the premise of reducing processing costs.

[0005] With the development of society, it is very important to reduce manufacturing costs and improve market competitiveness while meeting the needs of use. There are many ways for existing shavers to achieve head floating, such as a petal-shaped blade mesh seat that can float up and down with the outer side near the center end as a pivot, and a floating bracket that can achieve blade mesh seat floating. However, the floating assembly components of the shaver head in these two ways have more structural parts, complex assembly, and high manufacturing costs, so improvements are needed. Utility Model Content

[0006] The technical problem to be solved by the present application is to provide a floating razor head, which achieves the purpose of floating the blade mesh seat through floating spring pieces and supporting points on the head cover, simplifies the assembly steps and reduces the manufacturing cost.
