Description

Technical Field

[0001] This utility model relates to the field of cosmetic sample collection technology, specifically a sample extraction device for cosmetic testing. Background Technology

[0002] Cosmetics are applied directly to the skin and body, so their ingredients and quality are crucial to the safety and health of users.

[0003] Traditional sampling and testing devices require cosmetics to be stored in storage tanks after production. Sampling is then performed inside these tanks. However, with traditional equipment, workers must manually enter the storage tanks with a sampler, which is cumbersome, inefficient, and poses safety risks due to the close proximity to the tank's interior. This makes manual sampling extremely inconvenient and difficult to achieve convenient sample collection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sample extraction device for cosmetic testing, which has the advantages of convenient, safe and fast sampling, and solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a sample extraction device for cosmetic testing, comprising a sampling tube, a pull rod movably sleeved in the inner cavity of the sampling tube, a sealing plug fixedly fitted on the outer wall of the pull rod, a moving plate fixedly fitted on the outer wall of the pull rod, a drive rod fixedly fitted on the outer wall of the moving plate, a toothed plate fixedly fitted on the outer wall of the drive rod, a support base fixedly fitted on the outer wall of the sampling tube, an installation base fixedly fitted on the outer wall of the sampling tube, a drive motor fixedly fitted in the inner cavity of the installation base, a drive gear fixedly fitted on the power output shaft of the drive motor, a fixing base fixedly fitted on the outer wall of the sampling tube, a lifting plate movably sleeved in the inner cavity of the fixing base, a clamping plate fixedly fitted on the outer wall of the lifting plate, a fixing rod fixedly fitted on the top of the fixing base, a drive spring movably sleeved on the outer wall of the fixing rod, a connecting tube fixedly fitted on the outer wall of the sampling tube, and a storage cylinder threadedly connected to the outer wall of the connecting tube.

[0006] As a preferred technical solution of this utility model: the inner cavity of the support seat is movably sleeved with a driving rod, and the outer wall diameter of the sealing plug is equal to the inner wall diameter of the sampling tube.

[0007] As a preferred technical solution of this utility model: the outer wall of the drive gear meshes with the outer wall of the toothed plate, and the inner wall shape of the clamping plate matches the outer wall shape of the drive rod.

[0008] As a preferred technical solution of this utility model: there are two drive rods, and the two drive rods are respectively installed on both sides of the outer wall of the moving plate.

[0009] As a preferred technical solution of this utility model: the outer wall of the fixed rod passes through the inner cavity of the lifting plate, and the inner cavity of the lifting plate passes through the inner cavity of the fixed seat and contacts the outer wall of the drive rod.

[0010] As a preferred technical solution of this utility model: the two ends of the outer wall of the drive spring are in contact with the outer wall of the lifting plate and the outer wall of the fixing rod, respectively, and the drive spring is made of high carbon steel.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This sample extraction device for cosmetic testing allows cosmetics from the storage container to enter the sampling tube through a sampling tube. By moving the sealing plug, the cosmetics can then flow along the connecting tube into the storage container. After sampling, the sealing plug is moved forward to disconnect the connecting tube, thus enabling the sampling of cosmetics. This avoids the need for manual operation of the sampler in traditional equipment, making sampling more convenient and improving the overall safety of use.

[0013] 2. This sample extraction device for cosmetic testing uses a fixed seat on the outer wall of the sampling tube and a lifting plate on the outer wall of the fixed seat. The outer walls of the lifting plate and the clamping plate contact the drive rod, and the lifting plate and the clamping plate can lock the outer wall of the drive rod, so that the drive rod, the pull rod and the sealing plug cannot move, ensuring that the cosmetic in the sampling tube cannot enter the connecting tube, thus achieving better sealing of the sampling tube.

[0021] Please see Figure 1 - Figure 5 A sample extraction device for cosmetic testing includes a sampling tube 1, a pull rod 2 movably sleeved inside the sampling tube 1, a sealing plug 3 fixedly mounted on the outer wall of the pull rod 2, a moving plate 4 fixedly mounted on the outer wall of the pull rod 2, a drive rod 5 fixedly mounted on the outer wall of the moving plate 4, a toothed plate 6 fixedly mounted on the outer wall of the drive rod 5, a support seat 7 fixedly mounted on the outer wall of the sampling tube 1, an installation seat 8 fixedly mounted on the outer wall of the sampling tube 1, a drive motor 9 fixedly mounted inside the installation seat 8, a drive gear 10 fixedly mounted on the power output shaft of the drive motor 9, a fixed seat 11 fixedly mounted on the outer wall of the sampling tube 1, a lifting plate 12 movably sleeved inside the fixed seat 11, a clamping plate 13 fixedly mounted on the outer wall of the lifting plate 12, a fixed rod 14 fixedly mounted on the top of the fixed seat 11, a drive spring 15 movably sleeved on the outer wall of the fixed rod 14, a connecting tube 16 fixedly mounted on the outer wall of the sampling tube 1, and a storage cylinder 17 threadedly connected to the outer wall of the connecting tube 16.

[0022] In the above structure, by adjusting the positions of the pull rod 2 provided in the inner cavity of the sampling tube 1 and the sealing plug 3 provided on the outer wall of the pull rod 2, the sealing plug 3 can be moved to the side closer to the moving plate 4, thereby enabling the inner cavity of the connecting tube 16 to communicate with the inner cavity of the sampling tube 1 at the end away from the connecting tube 16.

[0023] In a preferred embodiment: the inner cavity of the support 7 is movably fitted with a drive rod 5, and the outer diameter of the sealing plug 3 is equal to the inner diameter of the sampling tube 1.

[0024] In the above structure, the support seat 7 provided on the outer wall of the sampling tube 1 can restrict the outer wall of the drive rod 5 under the action of the support seat 7, so that the drive rod 5 can move in the inner cavity of the support seat 7, thereby moving the outer wall of the sealing plug 3 to the position of the inner cavity of the sampling tube 1 close to the connecting tube 16, so that the sample can enter the inner cavity of the connecting tube 16 through the inner cavity of the sampling tube 1.

[0025] In a preferred embodiment, the outer wall of the drive gear 10 meshes with the outer wall of the toothed plate 6, and the inner wall shape of the clamping plate 13 matches the outer wall shape of the drive rod 5.

[0026] In the above structure, the drive motor 9 installed in the inner cavity of the mounting base 8 and the drive gear 10 provided on the outer wall of the drive motor 9 can drive the drive gear 10 under the action of the drive motor 9, so that the drive gear 10 can drive the drive rod 5 during rotation, thereby driving the pull rod 2 to move along the inner cavity of the sampling tube 1 to release the sample.

[0027] In a preferred embodiment, there are two drive rods 5, and the two drive rods 5 are respectively installed on both sides of the outer wall of the movable plate 4.

[0028] In the above structure, the drive rods 5 installed on both sides of the outer wall of the moving plate 4, and the drive motor 9 and drive gear 10 installed in the inner cavity of the mounting base 8, can drive the drive rods 5 under the action of the drive motor 9, thereby moving the position of the pull rod 2 and the sealing plug 3, so as to better realize the sampling of cosmetic samples.

[0029] In a preferred embodiment: the outer wall of the fixed rod 14 passes through the inner cavity of the lifting plate 12, and the inner cavity of the lifting plate 12 passes through the inner cavity of the fixed seat 11 and contacts the outer wall of the drive rod 5.

[0030] In the above structure, the lifting plate 12 is provided in the inner cavity of the fixed seat 11, so that the outer wall of the lifting plate 12 contacts the outer wall of the drive rod 5. Thus, the lifting plate 12 restricts the outer wall of the drive rod 5, so that the drive rod 5 cannot move, and thus the sealing plug 3 cannot move in the inner cavity of the sampling tube 1, thereby locking the sealing plug 3.

[0031] In a preferred embodiment, the two ends of the outer wall of the drive spring 15 are in contact with the outer wall of the lifting plate 12 and the outer wall of the fixing rod 14, respectively, and the drive spring 15 is made of high carbon steel.

[0032] In the above structure, the drive spring 15 provided on the outer wall of the fixed rod 14 can drive the outer wall of the lifting plate 12 under the action of the drive spring 15, so that the outer wall of the lifting plate 12 contacts the outer wall of the drive rod 5, thereby fixing the drive rod 5, preventing the drive rod 5 from moving in the inner cavity of the support seat 7, and preventing the cosmetics from detaching from the inner cavity of the sampling tube 1 and the connecting tube 16.

[0033] Working Principle: During operation, when sampling cosmetics is required, the sampling tube 1 is installed outside the cosmetic storage container. Pulling the lifting plate 12 upward compresses the drive spring 15, causing the lifting plate 12 to move the outer wall of the clamping plate 13 upward. This causes the outer wall of the clamping plate 13 to detach from the outer wall of the drive rod 5. Starting the drive motor 9 rotates the drive gear 10, which in turn drives the drive rod 5. This causes the pull rod 2 and the sealing plug 3 to move along the inner cavity of the sampling tube 1. When the outer wall of the sealing plug 3 exceeds the connecting tube 16 during its movement, the cosmetics inside the storage container are sampled. The sample enters the inner cavity of the sampling tube 1 through the inner cavity of the connecting tube 16 and then into the inner cavity of the storage cylinder 17, thus collecting the sample for testing. After the sample collection is completed, the drive motor 9 is started again. Under the action of the drive motor 9 and the drive gear 10, the pull rod 2 and the sealing plug 3 move to the end of the inner cavity of the sampling tube 1 away from the connecting tube 16, thereby sealing the connecting tube 16 and preventing the sample from entering the inner cavity of the connecting tube 16. Then, the lifting plate 12 is released. Under the action of the drive spring 15, the lifting plate 12 is driven, so that the outer wall of the lifting plate 12 and the clamping plate 13 contacts the outer wall of the drive rod 5, locking the drive rod 5 and preventing its movement, thereby sealing the inner cavity of the sampling tube 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
