The cosmetic bottle to be sampled and detected is a canned cosmetic bottle, the upper end opening of the cosmetic bottle is large, and meanwhile, a large amount of samples exist in the same plane for cosmetics inside, so that multiple points inside the cosmetic bottle need to be sampled respectively.

The sampling assembly 5 comprises an outer tube 51 slidably connected in the upper housing 2, and an inner rod 52 slidably connected in the outer tube 51 in a sealing manner along the up-down direction; the lower end of the inner wall of the outer tube 51 is provided with a sampling opening 511 communicated with the outer wall of the outer tube 51; each outer tube 51 in the upper shell 2 is distributed and arranged at equal intervals along the circumferential direction, so that samples can be taken from different positions of the same depth, the sporadic nature of the samples is reduced, and the detection accuracy is further improved.

When the synchronizing bolt 56 is inserted into the valve plate 53, the upward sliding of the valve plate 53 causes the inner rod 52 to slide upward, the sample is drawn into the outer tube 51, the synchronizing bolt 56 slides into engagement with the outer tube 51, the downward sliding of the valve plate 53 causes the valve plate 53 to close the sampling opening 511, and the inner rod 52 does not slide.

When the synchronizing bolt 56 is inserted into the outer tube 51, the upward sliding of the valve plate 53 causes the valve plate 53 not to close the sampling opening 511, the synchronizing bolt 56 is slid into engagement with the valve plate 53, the downward sliding of the valve plate 53 causes the inner rod 52 to slide downward, and the sample in the outer tube 51 is extruded.

The inner wall of the valve plate 53 is formed with a synchronous jack 531 which can be inserted into the synchronous plug pin 56 to enable the valve plate 53 and the inner rod 52 to slide synchronously; the inner wall of the outer tube 51 is formed with a fixing insertion hole 512 which can be inserted into the synchronizing pin 56 to fix the inner rod 52 and the outer tube 51 relatively; when the valve plate 53 is positioned at the upper limit position relative to the outer tube 51, the axes of the synchronizing jack 531, the fixing jack 512 and the synchronizing bolt 56 are collinear.

The outer wall of the switching tube 54 is fixedly connected with a magnet 541 which is eccentrically arranged and can magnetically attract the synchronous bolt 56 so as to enable the synchronous bolt 56 to slide; the synchronizing bolt 56 is made of magnetic metal, such as iron, and can be magnetically attracted by the magnet 541 to slide.

When the synchronizing bolt 56 is inserted into the synchronizing receptacle 531, the upward sliding of the valve plate 53 causes the synchronizing bolt 56 to slide into the fixed receptacle 512, the downward sliding of the valve plate 53 causes the switching tube 54 to rotate a half turn, and the magnet 541 rotates to a limit position close to the synchronizing receptacle 531.

When the synchronizing bolt 56 is inserted into the fixed insertion hole 512, the upward sliding of the valve plate 53 causes the synchronizing bolt 56 to slide into the synchronizing insertion hole 531, the downward sliding of the valve plate 53 causes the switching tube 54 to rotate for half a turn, and the magnet 541 rotates to a limit position close to the fixed insertion hole 512.

A driving tube 55 is rotatably connected to the outer periphery of the outer tube 51 above the switching tube 54; a section of spiral groove 551 which is spirally arranged is formed on the inner wall of the driving pipe 55, and a driving sliding column 532 which is in sliding connection with the spiral groove 551 is fixedly connected with the outer wall of the valve plate 53; sliding of the valve plate 53 causes the drive spool 532 to move within the helical groove 551, and the drive tube 55 to rotate; the rotation direction of the driving tube 55 is synchronously changed with the sliding direction of the valve plate 53.

The upper end of the switching tube 54 is fixedly connected with a driven ratchet 542 with an axis coincident with the rotating shaft of the switching tube 54, and the lower end of the driving tube 55 is fixedly connected with a driving ratchet 552 with an axis coincident with the rotating shaft of the driving tube 55 and connected with the driven ratchet 542 in a unidirectional transmission manner.

The upward sliding of the valve plate 53 only drives the driving tube 55 to rotate forward, and the downward sliding of the valve plate 53 to the lower limit position makes the driving tube 55 drive the switching tube 54 to rotate reversely and synchronously for half a turn.

The upper housing 2 is cylindrical, and a plurality of outer tube sliding grooves 22 which are arranged along the radial direction and are respectively connected with the corresponding outer tubes 51 in a sliding manner are formed in the bottom of the upper housing 2, and each outer tube 51 can only slide in the corresponding outer tube sliding groove 22 and cannot rotate.

An upper rotary table 3 which is arranged with a rotary shaft overlapped with the axis of the upper shell 2 is connected with the upper shell 2 in a rotary way; the upper turntable 3 is formed with a plurality of inclined adjusting sliding grooves 31 which are respectively connected with the corresponding outer tube 51 in a sliding manner.

During the rotation of the upper rotating disc 3, the adjusting chute 31 pushes the outer tube 51 to slide in the outer tube chute 22, the distance between the outer tube 51 and the axis of the upper housing 2 is changed, and the sampling opening 511 on each outer tube 51 horizontally moves at the same depth in the cosmetic bottle, so that the outer tube 51 can sample from any position at the same depth.

A lower supporting disc 1 which can be placed at the opening of the cosmetic bottle is connected below the upper shell 2 in a sliding manner; a compression spring 12 for pushing the upper shell 2 to move upwards and reset relative to the lower support disc 1 is arranged between the lower support disc 1 and the upper shell 2; a blocking disc 71 capable of abutting against the upper shell 2 to prevent the outer tube 51 from continuing to slide downwards is arranged above the lower abutting disc 1; a threaded hole is formed in the center of the blocking disc 71, and a screw rod 72 in transmission connection with the threaded hole is rotatably connected to the inside of the lower supporting disc 1; a transmission gear 73 in transmission connection with the screw rod 72 is rotatably connected inside the lower support plate 1, and a lower swivel 4 for driving the transmission gear 73 to rotate is rotatably connected outside the lower support plate 1; the inner wall of the lower swivel 4 is formed with an inner gear ring 41 which is arranged along the circumferential direction and is in driving connection with the driving gear 73.

When the upper housing 2 abuts against the blocking plate 71, the outer tube 51 cannot slide down further, and each outer tube 51 samples the depth at which the sampling opening 511 is located.

When the upper housing 2 abuts against the blocking disc 71 at different positions, the sliding distance of the upper housing 2 relative to the lower supporting disc 1 is different, and the depth of the sampling opening 511 is different, so that cosmetics at different depths in the cosmetic bottle can be sampled.

A lifting disc 6 which can drive the valve plate 53 to slide upwards relative to the outer tube 51 is connected in the upper shell 2 in a sliding manner along the up-down direction; a tension spring is arranged between the valve plate 53 and the outer tube 51 to drive the valve plate 53 to slide downwards relative to the outer tube 51.

The lower end of the lifting disc 6 is fixedly connected with a plurality of lower supporting columns 62 which are arranged at equal intervals along the circumferential direction and can support against the upper end of the blocking disc 71, and the lower supporting columns 62 extend out of the lower end face of the upper shell 2, so that in the downward movement process of the upper shell 2, the lower supporting columns 62 are contacted with the blocking disc 71 firstly, and then the upper shell 2 is contacted with the blocking disc 71.

The downward sliding of the upper housing 2 can drive the lower abutment post 62 to abut against the blocking disc 71, so that the lifting disc 6 slides upwards relative to the upper housing 2; a return spring 63 is arranged between the lifting disk 6 and the upper housing 2 to drive the lifting disk 6 to slide downwards relative to the upper housing 2.

When the lower abutment post 62 abuts against the blocking disc 71, the downward sliding of the upper housing 2 causes the lifting disc 6 to slide upward relative to the upper housing 2, and the valve plate 53 to slide upward relative to the outer tube 51.

When the upper housing 2 abuts against the blocking disc 71, the lifting disc 6 is located at an upper limit position with respect to the upper housing 2, and the valve plate 53 is located at an upper limit position with respect to the outer tube 51.

A plurality of guide slide grooves 61 which are respectively overlapped with the outer pipe slide grooves 22 in the up-down direction are formed on the lifting disk 6; the upper end of the valve plate 53 is fixedly connected with a valve plate sliding column 534 which is in sliding connection with the guide chute 61, and the upper end of the valve plate sliding column 534 is fixedly connected with a synchronous plate 533 which is propped against the upper end of the lifting disc 6; the width of the guide sliding groove 61 is equal to the diameter of the valve plate sliding column 534, and the width of the guide sliding groove 61 is smaller than the diameter of the synchronizing plate 533, so that when the lifting disk 6 moves upward, the upper end of the lifting disk 6 abuts against the lower end of the synchronizing plate 533 and pushes the valve plate 53 upward.

The sampling opening 511 communicates with the side wall of the outer tube 51, not with the lower end of the outer tube 51; the lower end of the outer tube 51 is formed with a material stirring inclined plane 513 which is obliquely arranged; the direction of inclination of the kick-out ramp 513 is opposite to the direction of the sampling opening 511.

In the process of downward movement of the outer tube 51, the material-pulling inclined plane 513 contacts with the cosmetics and pushes the cosmetics away from the sampling opening 511, so as to prevent the cosmetics on the upper layer from being pressed into the sampling opening 511, and prevent the cosmetics attached to the outer wall of the outer tube 51 from entering the outer tube 51 along the outer wall of the outer tube 51, thereby affecting the sampling result.

A plurality of cleaning sliding grooves 11 which are respectively overlapped with the outer pipe sliding grooves 22 in the vertical direction are formed in the bottom of the lower supporting plate 1, and a cleaning sleeve 57 for removing cosmetics attached to the outer wall of the outer pipe 51 is connected in a sliding manner in the horizontal direction in each cleaning sliding groove 11.

The cleaning sleeve 57 is made of an elastic material such as rubber, and the cleaning sleeve 57 is closely attached to the outer wall of the outer tube 51 and scrapes off the attached cosmetics when the outer tube 51 is moved from the cleaning sleeve 57, and the cleaning sleeve 57 can be re-closed when the outer tube 51 is moved from the cleaning sleeve 57.

The upper end and the lower end of the inner wall of the cleaning chute 11 are formed with ribs for restricting the movement of the cleaning sleeve 57, so that the cleaning sleeve 57 can only slide in the cleaning chute 11 in the horizontal direction but cannot slide up and down along with the outer tube 51.

During the upward movement of the outer tube 51, the outer tube 51 having the cosmetics thereon is rubbed against the cleaning sleeve 57, and the cosmetics attached to the outer tube 51 are separated from the outer tube 51, thereby preventing the cosmetics in the non-sampling area from being mixed into the sample and affecting the result.

The lower extreme shaping of upper turntable 3 has a plurality of rotation stopping bayonet socket 32 that set up along circumference equidistant, the inner wall fixedly connected with of upper casing 2 can with the rotation stopping bayonet socket 32 joint's the rotation stopping card post 21 that is made by elastic material.

When the upper turntable 3 is stressed to rotate, the rotation stopping clamping column 21 is not clamped with the rotation stopping bayonet 32; when the upper housing 2 slides downwards, the anti-rotation clamping posts 21 are clamped with the anti-rotation clamping bayonets 32, so that the upper turntable 3 cannot rotate relative to the upper housing 2, and the outer tubes 51 cannot slide relative to the upper housing 2.

The upper end of the inner wall of the outer tube 51 is formed with a rotation stopping hole 514 with a non-circular cross section, and the upper end of the inner rod 52 is fixedly connected with a rotation stopping column 521 with the same cross section as the rotation stopping hole 514.

The outer wall of the outer tube 51 is fixedly connected with a rotation stopping slide block 515 which is in sliding connection with the outer tube chute 22; the rotation stop slide 515 is non-circular in cross section such that the outer tube 51 can only slide along the outer tube chute 22 and cannot rotate.

In the initial state, the upper housing 2 is located at an upper limit position relative to the lower support plate 1, the lifting plate 6 is located at a lower limit position relative to the upper housing 2, the synchronizing bolt 56 is inserted into the synchronizing jack 531, and the magnet 541 is located at one side close to the fixed jack 512.

Along with the improvement of living standard, cosmetics are also continuously popularized, and necessary detection work is indispensable because the cosmetics are in direct contact with human skin; in order to improve the accuracy of detection, cosmetics at each point in a cosmetic bottle are often sampled, and the existing sampling equipment samples by extending a needle into different depths, in the sampling process, the cosmetics at the upper layer can be pressed into the needle to influence the detection result, and meanwhile, most of sampling equipment cannot adjust the size according to the cosmetic bottle, so that the universality is low; for this purpose, a device is needed which is capable of adjusting the sampling area and sampling only the sampling area.

When the utility model is used, the handle 20 is held by one hand, the upper rotary table 3 is held by the other hand and rotated, the rotation of the upper rotary table 3 drives each adjusting chute 31 to rotate, the inner wall of each adjusting chute 31 is extruded by the corresponding adjusting chute 31 to extrude the corresponding outer tube 51, the outer tube 51 moves in the corresponding outer tube chute 22, namely, the outer tube 51 slides relative to the upper shell 2, and the interval between the two adjacent outer tubes 51 is adjusted; in the rotating process of the upper turntable 3, the inner wall of the rotation stopping bayonet 32 presses the rotation stopping clamping column 21 to enable the rotation stopping clamping column 21 to deform and not be clamped with the rotation stopping bayonet 32, when the upper turntable 3 rotates until the next rotation stopping bayonet 32 is aligned with the rotation stopping clamping column 21, the rotation stopping clamping column 21 is restored and clamped with the rotation stopping bayonet 32 which is aligned at the moment.

When the position of each outer tube 51 meets the sampling requirement, the rotation of the upper rotary table 3 is stopped, and the rotation stopping clamping columns 21 and the rotation stopping clamping openings 32 are clamped at the moment, so that each outer tube 51 cannot slide relative to the upper shell 2; each outer tube 51 is then brought into facing relation with the opening of the cosmetic bottle and the lower support plate 1 is placed over the opening of the cosmetic bottle.

Then the hand which originally holds the upper turntable 3 moves to hold the lower swivel 4 and rotates, the rotation of the lower swivel 4 drives the inner gear ring 41 to rotate so that the transmission gear 73 rotates, the rotation of the transmission gear 73 drives the synchronous belt to rotate so that the screw rod 72 rotates, and the rotation of the screw rod 72 drives the blocking disc 71 to slide because the blocking disc 71 only slides up and down relative to the lower supporting disc 1 and cannot rotate relatively.

Then, the hand which originally holds the lower swivel 4 is moved to hold the cosmetic bottle, and then the other hand presses the handle 20 downwards, the movement of the handle 20 drives the upper shell 2 to synchronously move downwards, and the compression spring 12 contracts to store the force; since the outer tube 51 can only slide in the horizontal direction relative to the upper housing 2, the downward movement of the upper housing 2 drives each outer tube 51 to move downward synchronously, the lower end of the outer tube 51 extends out from the lower end of the lower support plate 1 and into the cosmetic bottle, and at this time, the lifting plate 6 is kept at the lower limit position relative to the upper housing 2 under the action of the return spring 63, and the valve plate 53 keeps closing the sampling opening 511.

After the outer tube 51 moves downwards until the stirring inclined plane 513 contacts with the cosmetics, the continuous downwards movement of the outer tube 51 enables the stirring inclined plane 513 to push the cosmetics to move, so that the cosmetics on the upper layer cannot be extruded and accumulated on the outer wall of the outer tube 51, the cosmetics pushed by the stirring inclined plane 513 move in the direction away from the sampling opening 511, even if partial cosmetics remain on the stirring inclined plane 513, the sampling of the sampling opening 511 on the other side cannot be influenced, the mixing of the cosmetics on the upper layer is avoided, the accuracy of the sampling result is prevented from being influenced,

after the upper shell 2 moves downwards until the lower supporting column 62 on the lifting disk 6 abuts against the blocking disk 71, the lifting disk 6 cannot move downwards continuously, and at this time, the sampling openings 511 on the outer tubes 51 are positioned on the same horizontal plane with the cosmetics to be detected; subsequently, the handle 20 is continuously pressed downwards, the upper shell 2 continuously moves downwards, at this time, the lifting disk 6 slides upwards relative to the upper shell 2, the restoring spring 63 contracts to store force, the sliding of the lifting disk 6 drives each synchronizing plate 533 to move upwards, so that each valve plate 53 moves upwards relative to the corresponding outer tube 51, and the tension spring stretches to store force.

Because the synchronous plug pin 56 is inserted into the synchronous jack 531 at this time, the sliding of the valve plate 53 drives the inner rod 52 to synchronously slide upwards relative to the outer tube, the valve plate 53 does not close the sampling opening 511 any more, the sliding of the inner rod 52 plays a role of a piston, so that the pressure in the outer tube 51 is reduced, and the cosmetics outside the sampling opening 511 are sucked into the outer tube 51; meanwhile, the sliding of the valve plate 53 drives the driving sliding column 532 to move in the spiral groove 551, so that the driving tube 55 rotates in the forward direction, at this time, the driving ratchet 552 does not drive the driven ratchet 542 to rotate, and the switching tube 54 remains stationary.

When the upper shell 2 moves to prop against the blocking disc 71, the valve plate 53 moves to an upper limit position relative to the outer tube 51, at this time, the synchronizing bolts 56 on each inner rod 52 are opposite to the fixed jacks 512, the synchronizing bolts 56 move to be spliced with the fixed jacks 512 under the magnetic attraction of the magnet 541, the synchronizing bolts 56 are not spliced with the synchronizing jacks 531, and at this time, the inner rods 52 are fixed relative to the outer tube 51; at the same time, a sufficient amount of cosmetic in the cosmetic bottle is sucked into the outer tube 51, completing the sampling.

According to the different positions of the blocking disc 71, the distance that the upper housing 2 moves relative to the lower supporting disc 1 is different, so that the moving depth of the outer tube 51 is changed, and cosmetics with different depths in the cosmetic bottle can be sampled.

Then the handle 20 is released, the upper shell 2 moves upwards under the action of the elastic force of the compression spring 12, and in the upward movement process of the upper shell 2, the lifting disc 6 still keeps abutting against the blocking disc 71 under the action of the elastic force of the return spring 63, namely, at the moment, the lifting disc 6 moves downwards relative to the upper shell 2; meanwhile, the upward movement of the upper housing 2 drives each outer tube 51 to move upward, at this time, the valve plate 53 moves downward relative to the outer tube 51 under the action of the elastic force of the tension spring, while the inner rod 52 and the outer tube 51 remain fixed, and the inner rod 52 does not move downward; when the lifting disk 6 moves to the lower limit position with respect to the upper housing 2, the valve plate 53 closes the sampling opening 511, and the sample is stored in the outer tube 51 without contact with the cosmetic in the cosmetic bottle.

In the process of moving downwards relative to the outer tube 51, the valve plate 53 drives the sliding column 532 to move in the spiral groove 551 so that the driving tube 55 rotates, at this time, the rotation of the driving tube 55 drives the driving ratchet 552 to rotate so that the driven ratchet 542 rotates, and the rotation of the driven ratchet 542 drives the switching tube 54 to rotate so that the magnet 541 moves; when the valve plate 53 moves to the lower limit position with respect to the outer tube 51, the magnet 541 moves to a side close to the synchronizing receptacle 531.

The upward movement of the upper shell 2 drives the lifting disk 6 to move upward synchronously, each outer pipe 51 moves upward synchronously, and each cleaning sleeve 57 in the lower supporting disk 1 rubs with the outer wall of each outer pipe 51 respectively in the outer pipe 51 moving process, so that cosmetics attached to the outer wall of the outer pipe 51 are scraped off, and the cosmetics are prevented from being attached to the outer wall of the outer pipe 51, so that the subsequent detection process is influenced, or bacteria are caused to grow.
