Acne extractor

This creation is about a skin conditioning tool, especially an acne extractor.

Acne, also known as acne vulgaris, is a condition in which the skin has long-term blackheads, whiteheads (white or milky white thorny papules), acne, oily skin, or stubble. Most people have experience with long acne, and many people handle it by squeezing the affected part with a finger to push the pus in the acne or hair follicle out of the hair follicle. However, human fingers often carry many germs (especially in nail sutures), and if they are squeezed directly with a finger without being cleaned, it is very likely to cause infection and cause skin inflammation or even cellulitis.

Therefore, there are many devices on the market that replace the squeezing or plucking of acne. For example, a device commonly known as an acne stick or a youthful stick mainly presses an affected part with a ring to generate an average pressure around the affected part, and the acne or pus is pushed out from the hair follicle. In addition, as disclosed in Taiwan's new patent publication No. 489612 "Piece acne extractor": a cylinder block, one end of which is connected with the suction head, and the shaft pivot is at the center of the front end of the main body, and the other end is sleeved with a sleeve, and the sleeve is centrally pivoted. There is a piston shaft extending into the cylinder body to have a slidable tendency, the sleeve side wall is provided with a sliding button protruding outside the main body, and the main body side jaw wall is formed with a sliding slot corresponding to the sliding button. The utility model mainly drives the sliding button toward the rear end, and simultaneously drives the piston shaft to slide toward the rear end of the cylinder block to generate a negative pressure in the cylinder body to assist the acne or pus discharge.

However, the above-mentioned acne acne extractor can mechanically generate a negative pressure to assist the acne or pus and blood discharge, but when used, the tip must be placed around the affected part, and the plucking device is pressed toward the skin, and then the acne is pressed against the skin. The slider is pushed backwards to drive the piston shaft to slide toward the rear end of the cylinder block to generate a negative pressure, which is inconvenient to use. Therefore, the creator believes that there should be a more intuitive and fast acne extractor.

In view of the deficiencies of the prior art, the creator has created an acne extractor which defines the acne extractor as one of the human skin when it is in use, which includes a sleeve and a threaded a telescopic rod assembly in the sleeve, the lower end of the sleeve is provided with a suction section, the telescopic rod assembly comprises a mast with a lower section located in the suction section, and the mast is sealed with the suction section a ring plug; the telescopic rod assembly further includes a pressing rod extending through the upper end wall of the sleeve, the pressing rod and the mast being driven by the pressing rod and the mast movable in the opposite direction of the axial direction The transmission combination is formed, so that when the pressure lever is axially moved downward in the use state, the mast is simultaneously moved axially upward, thereby generating a negative pressure inside the suction section.

When the pressing rod is pressed toward the human skin, the pressing rod is simultaneously retracted into the sleeve downward, and the mast is moved in the opposite direction to make the entire telescopic rod assembly compressed. The airtight ring is inserted into the airtight space between the skin of the affected part to generate a negative pressure to further provide the suction force of the acne outward, so that the acne is more easily removed from the hair follicle. The main advantage of this creation is that the acne extractor only needs to press the pressure bar around the affected part, which can simultaneously produce the effect of "squeezing" and "sucking" on the affected part to remove acne. The process is easier to operate and convenient.

The construction, features and embodiments of the present invention will be described with the aid of the drawings, and the reviewers will have a better understanding of the present invention.

Please refer to the first figure. As shown in the second and third figures, this creation is about an acne extractor (A), which is mainly used to press around the affected part of the acne and simultaneously generate negative pressure to assist the acne to discharge the hair follicle. Among them, the acne refers to the skin secretions, metabolic waste, dust, pus and blood accumulated in the hair follicles, commonly known as whitehead acne, blackhead acne, acne and other skin diseases.

The acne extractor (A) is defined as one side facing the human skin in the state of use, and includes a sleeve (1), and a telescopic rod assembly (2) disposed in the sleeve (1) The lower end of the sleeve (1) is provided with a suction section (11), and the telescopic rod assembly (2) The mast (21) of the lower section (21A) located in the sucking section (11) is included, and a gas tight loop plug (211) is interposed between the mast (21) and the sucking section (11). As shown in the third figure, the inner edge of the airtight ring plug (211) can be tightly fixed to the lower portion (21A) of the mast, and the outer edge thereof is tightly and airtightly formed with the inner wall of the suction section (11). In order to form an airtight space between the airtight ring plug (211) and the affected part skin (B). In addition, the implementation of the airtight ring plug (211) is not limited thereto. Referring to the sixth figure, the airtight ring plug (211) may also be implemented as: the airtight ring plug (211) is clamped to a pad. The sheet (111) and the upper end of the sucking section (11) form a tight joint with the sucking section (11), and the inner edge thereof is tightly and airtight with the outer wall of the mast (21) to be in use. At the same time, the airtight ring plug (211) forms an airtight space between the skin of the affected part.

The telescopic rod assembly (2) further includes a pressing rod (23) extending through the upper end wall (12) of the sleeve (1), the pressing rod (23) and the mast (21) passing the pressing rod (23) and the mast (21) is movable in the opposite direction of the axial direction to form a transmission coupling, so that when the lever (23) is operatively moved axially downward in use, the vehicle is simultaneously driven The mast (21) moves axially upwards, thereby creating a negative pressure inside the suction section (11).

As shown in the fourth figure, the acne extractor (A) is used to apply the lower end of the sucking section (11) to the skin around the skin (B) of the human acne and is applied to the pressure bar (23). The pressure toward the direction of the human skin (defined as the lower side) causes the acne to be squeezed outward due to the pressure on the surface of the skin around the affected part. With the setting of the swaying element (22), when the pressing rod (23) is pressed toward the human skin, it is simultaneously retracted downward into the sleeve (1), and the mast (21) is interlocked in the opposite direction. (moving away from the direction of the human skin, defined as the upper side) moves, so that the entire telescopic rod assembly (2) is in a compressed state, thereby causing a negative pressure in the airtight space between the airtight ring plug (211) and the affected part skin (B) To further provide the external suction of the acne, so that the acne is more easily removed from the hair follicle. The main part of this creation The utility model has the advantages that: when the acne extractor (A) is used, only the pressing rod (23) needs to be pressed toward the surrounding part of the affected part, so that the effect of "squeezing" and "sucking" can be simultaneously generated on the affected part to remove the acne extractor (A). The acne process is easier to handle and convenient.

In a preferred embodiment, a spring (232) is disposed outside the pressing rod (23), the upper end of the spring (232) abuts the upper end block (231) of the pressing rod, and the lower end abuts against the sleeve (1) The upper end wall (12). Thereby, when the pressing rod (23) is forced downward to make the telescopic rod assembly (2) as a whole compressed state, the original tension state can be restored by the restoring force of the spring (232). In this way, when the creation is used, it can be automatically restored to the stretched state after one press, and the next press can be used immediately, so that the use process of the creation is faster and more convenient.

In a preferred embodiment, the suction section (11) is operatively screwed to the lower end of the sleeve (1) to allow the suction section (11) to be removed for cleaning or to be replaced with a different size. The lower section (21A) of the mast is preferably operatively coupled to the remainder of the mast (21). The top end of the mast lower portion (21A) is provided with a tenon (215), and the bottom end of the remaining portion of the mast (21) is provided with a pair of holes (216) which should be convex (215) to make the mast The lower section (21A) was replaced. The above settings allow the user to replace the suction section (11) and the lower section of the mast (21A) according to the situation (such as wear, dirt or size mismatch). For example, pustules formed by acne are usually larger than whitehead acne, and can be replaced with a larger suction section (11) and a mast (21) to treat pustules of acne.

In a preferred embodiment, the swaying element (22) includes a hollow spiral body (221), and the upper portion of the spiral body (221) is opposite to and spirally connected to the lower portion (if the upper portion is left-handed, the lower portion) The part is right-handed, and so on.) The spiral body (221) relatively defines a screw groove (221A) above the upper section and a screw below the lower section. Ditch (221B).

The sleeve (1) has a straight hole unit (10) along the axial direction of the tube wall, and a first pin member (230) is disposed at the lower end portion of the sleeve (23) and is disposed at the same time. In the straight hole unit (10), a second pin member (210) is disposed at the upper end portion of the mast (21) and is inserted into the lower screw groove (221B) and the straight hole unit (10). When the pressing rod (23) is forced to move in the axial direction, the straight hole unit (10) can provide the pressure rod (23) and the limit rotation direction of the mast (21), so that the first pin The piece (230) moves along the straight hole unit (10) to rotate the screw body (221) for a hoop movement, thereby axially pushing the second pin member (210) to move the mast (21) in the opposite direction. . The embodiment of the straight hole unit (10) is not limited to a continuous straight hole as shown in the figure, but may also be implemented by a discontinuous straight hole.

7A and 7B are schematic diagrams showing the relative positions of the upper and lower spiral grooves (221A, 221B) and the straight hole unit (10) of the present invention in a laterally expanded manner into a two-dimensional plane. Referring to FIG. 7A, the portion indicated by the solid line is the straight hole unit (10), the first pin member (230), and the second pin member (210) in the compressed state of the telescopic rod assembly (2). ) the relative position of the upper threaded groove (221A) and the lower threaded groove (221B) (which is originally a spiral shape and the lower spiral groove is imaginarily expanded laterally and becomes a straight oblique groove); a position of the first and second pin members (230', 210') and the upper and lower thread grooves (221A', 221B') in a stretched state with respect to the compressed state; the upper thread groove ( The helix angle of 221A) is β ₁ , and the helix angle of the lower spiral groove (221B) is β ₂ (the helix angle is defined as the acute angle between the tangent of the helix and the axial straight line).

When the pressing rod (23) is pressed axially downward into the sleeve (1), the first pin member (230) is driven to move downward along the straight hole unit (10) (moved from 230' to 230) ),Simultaneously The upper thread groove (221A) converts the axial linear thrust received by the pressing rod (23) into a moment that forces the spiral body (221) to rotate in a ring direction (as shown in the figure, the upper and lower thread grooves are The broken line positions 221A', 221B' push the lateral forces of the solid line positions 221A, 221B). At this time, the lower spiral groove (221B) also simultaneously converts the moment received by the spiral body (221) into pushing the second pin member (210) to move upward along the straight hole unit (10). The axial linear thrust moves the mast (21) upward, thereby causing the telescopic rod assembly (2) to form a compressed state as a whole (as shown in the fourth figure).

With the above arrangement, the spiral body (221) utilizes two counter-rotating spiral configurations and causes the axial movement of the pressing rod (23) and the mast (21) in a twisting manner, thereby The telescopic rod assembly (2) can form a relative compression or stretch in a small space. In this way, the acne extractor (A) can form an elongated pen-like shape as a whole, which is not only easier to grasp and is more convenient to carry around.

See Figure VII B, in a preferred embodiment, the lower spiral groove (221B) of the helix angle (β ₂₎ is smaller than the upper spiral groove (221A) of the helix angle (β _1), in order to make the When the first pin member (230) rotates the spiral body (221), the moving distance of the second pin member (210) is greater than the moving distance of the first pin member (230). In this way, the mast (21) can be moved up faster than the presser (23) is pressed during use, so that the use of the creation is more time-saving.

Referring to the first figure, in conjunction with the second and fourth figures, in a preferred embodiment, a shell tube (3) is sleeved on the outside of the pressing rod (23) and the sleeve (1). The upper end of the shell tube (3) is closed and abuts against the end block (231) above the pressing rod (23). By the arrangement of the shell tube (3), not only the overall shape of the creation is more beautiful, but also because the upper end is pressed against the pressing rod (23), it can be held by the user in the state of use, and is directly pressed against the skin. It can produce the effect of squeezing and sucking.

The side wall of the shell tube (3) is provided with a pressing member (31) for operatively pressing radially inwardly against the outer side wall of the sleeve (1). Thereby, when the telescopic rod assembly (2) is in a compressed state as a whole, the pressing member (31) can be pressed against the outer side wall surface of the sleeve (1), so that the sleeve (1) and the shell tube ( 3) Sliding interference is formed, and the telescopic rod assembly (2) is maintained in a compressed state to maintain a negative pressure state inside the suction section (11). In this way, the user can press the pressing member (31) as needed to maintain the negative pressure state, and pull the acne extractor (A) outward to provide a more intense plucking effect.

Referring to the sixth figure, when the telescopic rod assembly (2) is in a relatively stretched state, the lower end of the mast (21) is relatively bare from the lower end of the suction section (11). With this arrangement, when the acne in the affected part hair follicle is smoothly pulled out and left in the sucking section (11), the mast (21) is in the process of returning the stretched state of the telescopic rod assembly (2). At the same time, the foreign matter remaining in the sucking section (11) can be pushed out of the sucking section (11) to maintain the cleaning of the sucking section (11).

The lower end portion of the mast (21) is provided with a recessed groove (212) with an opening facing downward. The opening of the recessed groove (212) is provided with a bead body (213), and an elastic element is disposed in the recessed groove (212). 214) Abutting the top end of the recessed groove (212) and the bead body (213), the elastic member (214) may be a spring to retract the concave groove (212) when the bead body (213) is pressed. )Inside. This arrangement can provide cushioning when the lower end surface of the mast (21) bare from the lower end of the sucking section (11) touches the affected part of the skin acne without directly pressing the affected part to cause discomfort.
