Description

Technical Field

[0001] The invention relates to the technical field of underarm odor treatment, and in particular to an underarm odor hair follicle extraction device. Background Art

[0002] Hair follicles are sac-like tissues surrounding the roots of hair, mainly composed of epithelial cells and connective tissue. They are extremely important for the growth of hair, are the place where hair is produced and grows, and can provide nutrients for hair.

[0003] Underarm odor refers to the secretion of sweat with a special odor or the odor produced by sweat after decomposition. The existing treatment methods for underarm odor include topical medication, injection therapy and surgical treatment. Among them, topical medications such as aluminum chloride solution can reduce sweat secretion and bacterial growth, but the effect is not long-lasting; injection therapy inhibits sweat gland secretion by injecting botulinum toxin into the armpit, which can last for a period of time. In surgical treatment, traditional surgery directly removes the axillary apocrine tissue, which is more traumatic and takes a long time to recover; minimally invasive surgery such as small incision apocrine removal can remove apocrine glands with less trauma, and the postoperative scar is smaller. In this regard, in the prior art, the secretion of sweat can be reduced by removing the axillary odor hair follicles. In the prior art, the hair follicle extraction device mostly uses a rotary drill to cut the hair follicles from the surrounding skin tissues, and then uses tweezers to separate the hair follicles from the sebaceous glands to remove the hair follicles. The above device extracts the hair follicles, but it is necessary to use tweezers to remove the hair follicles later, and the steps are cumbersome. At the same time, the tweezers will carry part of the subcutaneous tissue in the process of removing the hair follicles, which causes great damage to the subcutaneous tissue. Summary of the invention

[0004] In view of this, the present invention proposes an underarm odor hair follicle extraction device to improve the efficiency of extracting hair follicles and reduce damage to subcutaneous tissue.

Two rotary cutters 25 are symmetrically and rotatably provided at the lower end of the inner cylinder 22. A driving module is provided on the outer wall of the inner cylinder 22. The power output end of the driving module is respectively connected to the driving input end of the two rotary cutters 25. The driving module drives the two rotary cutters 25 to rotate towards each other so as to extend out of the inner cylinder 22 and gather together to form an inner opening cutting and separation structure or extend into the inner cylinder 22 and gather together to form an outer opening tightening structure. A filter element 23 is detachably provided at the upper end of the inner cylinder 22. The extractor 10 has a negative pressure adsorption port, and the adsorption port is connected to an adsorption tube 30. The negative pressure adsorption end of the adsorption tube 30 extends into the filter element 23. The outer cylinder 21 is sleeved on the inner cylinder 22. An opening for the rotary cutter 25 to extend out of the inner cylinder 22 is provided at the lower end of the outer cylinder 21.

[0029] The present invention discloses a device for extracting hair follicles from underarm odor. When extracting hair follicles, the user holds the extraction pen 20 and places hair within 1 mm in length from the opening into the tightening structure. Then, the driving module is started. The driving module drives the rotary cutter 25 to rotate a certain angle, extend out of the inner cylinder 22, and then gather together to completely separate the hair follicle tissue from the skin tissue. Then, the extractor 10 turns on the negative pressure function to adsorb the hair follicle tissue removed by the rotary cutter 25 into the filter element 23, so that the hair follicle extraction and adsorption are completed in one piece. There is no need to use tweezers to clamp the hair follicles, thereby improving the extraction efficiency. At the same time, the two rotary cutters 25 gather together to form an inner opening cutting and separation structure, which can prevent the negative pressure mechanism of the extractor 10 from absorbing subcutaneous tissue, thereby reducing the damage to the subcutaneous tissue caused by the extracted hair follicles.
