Description

[0001] This invention claims priority to Chinese Patent Application No. 202111532116.6, filed with the Chinese Patent Office on December 14, 2021, entitled "A Hot and Cold Shaver", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention belongs to the technical field of razors, specifically relating to hot and cold razors. Background Technology

[0003] Shaving, commonly known as shaving, involves removing hair from the surface of an object using a razor. Beard generally refers to the hair growing on a man's upper lip, chin, cheeks, jaw, or neck. However, when people pick up a razor, the psychological satisfaction can be accompanied by physical pain, as the blade leaves a bloody cut. Now, these problems are entirely manageable. Over the past 150 years, people have developed safety razors, detachable blades, electric razors, and shaving cream.

[0004] When an electric shaver is working, the blades in the cutting unit rotate and rub against each other at high speed, generating a lot of heat that raises the temperature of the cutting unit. When the skin comes into contact with the cutting unit, this high temperature can cause discomfort to the skin.

[0005] Before shaving, a warm compress is needed to soften the beard and skin, making shaving easier. During and after shaving, an ice pack is applied to harden the beard and reduce pain. However, most razors on the market do not offer both warm and cold compresses, failing to meet users' shaving needs and resulting in a mediocre user experience. Furthermore, manual razors are cumbersome to assemble, with the razor head composed of multiple parts, leading to poor stability, inconvenient disassembly, and a complicated manufacturing process.

For example, without departing from the scope of the invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0073] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0074] Example 1

[0075] For ease of description, unless otherwise stated, the terms "up" and "down" in the following text refer to the same direction as "top" and "bottom". Figure 7 Its vertical direction is consistent with the horizontal direction mentioned below. Figure 7 Its left-right direction is consistent, and the front-back direction mentioned below is consistent with... Figure 8Its left and right directions are consistent.

[0076] like Figures 1 to 9 As shown, a hot and cold shaver includes a head 10, a handle 11, a blade assembly 13, a touch sensor 14, a heat transfer block 15, and an energy module 16. The energy module 16 is a semiconductor capable of generating heat and cooling. The blade assembly 13 includes multiple blades arranged in sequence.

[0077] The blade assembly 13 is detachably fixed to the outside of the shaving head 10 for easy assembly and replacement. The energy module 16 is disposed inside the shaving head 10 via a tactile plate 14; the tactile plate 14 is disposed on the side of the energy module 16 closest to the blade assembly 13, and the heat transfer block 15 is disposed on the other side of the energy module 16; the shaving head 10 is connected to the handle 11. The tactile plate 14, energy module 16, and heat transfer block 15 are stacked sequentially on the shaving head 10, making the overall space more compact. The tactile blocks 141 of the blade assembly 13 and the tactile plate 14 are located on the same surface of the shaving head 10. When shaving, the tactile blocks 141 of the tactile plate 14 abut against the skin. One side of the energy module 16 is connected to the tactile plate 14, and the other side of the energy module 16 is connected to the heat transfer block 15, which can transfer heat from the other side of the energy module 16 to the handle 11. When the touch-sensitive pad 14 is used for cooling, the heat transfer block 15 transfers heat from the other side to the handle 11, which facilitates heat dissipation from the energy module 16, raising the temperature of the handle 11 to warm the hands and fully utilize energy. The heat transfer block 15 is a semiconductor, which has excellent thermal conductivity, facilitating heat transfer. It also conducts heat away from the other side of the energy module 16, achieving a balance between heat generation and dissipation, thus maintaining normal operation. Before shaving, the energy module 16 heats the touch-sensitive pad 14 against the skin, opening pores and softening hair. After shaving, the energy module 16 cools the touch-sensitive pad 14, tightening the skin, shrinking pores, and relieving tingling.

[0078] In one embodiment, the support frame 111 of the handle 11 includes an upper housing 112 and a lower housing 113, which are detachably connected and form a hollow structure. Both the upper housing 112 and the lower housing 113 are provided with an extension hole 116 and a support hole 118.

The fixing cover 101 is installed in the groove. The support block 107 engages with the first fitting groove 1015 to support the fixing cover 101. The anti-detachment block 108 engages with the second fitting groove 1016 to fix the cutter head body 102 relative to the fixing cover 101. By applying external force to cause the anti-detachment block 108 to undergo elastic deformation, the cutter head body 102 can be separated from the fixing cover 101. The blade assembly 13 is detachably fixed to the outside of the fixing cover 101. The outside of the fixing cover 101 is provided with a blade groove 1012, and the blade assembly 13 is installed in the blade groove 1012.
