Technical Field
[0001] This utility model relates to the technical field of toothpaste production and research and development, and in particular to a staining mechanism and temperature control equipment. Background Technology
[0002] With the increasing health awareness and changing consumption concepts in modern society, consumers are paying more and more attention to oral care, which has driven the rapid development of the toothpaste market. Toothpaste varieties are becoming increasingly diversified, and consumers' functional demands for toothpaste are also becoming more varied. Toothpaste has a teeth-whitening effect. In the toothpaste production process, tooth samples need to be stained, and then a toothbrush with toothpaste is used to rub the tooth samples, simulating brushing, to determine the whitening effect of the toothpaste.
[0003] Currently, conventional tooth samples are typically soaked in a staining solution to stained them before being used in brushing tests. However, existing staining methods cannot simulate the oral cavity environment. Soaking tooth samples in the staining solution results in a significant color difference between the stained samples and actual teeth, making them unsuitable for subsequent brushing tests. Summary of the Invention
[0004] The purpose of this invention is to improve the problem that existing tooth samples cannot be used for brushing experiments after staining, and to provide a staining mechanism.
[0005] The technical solutions for achieving the above objectives include the following:

[0007] The device includes a drive assembly, a support member, a rotating shaft, and a dyeing rack. The drive assembly is mounted on the first end of the support member, the first end of the rotating shaft is mounted on the output end of the drive assembly, and the second end of the rotating shaft is rotatably disposed on the second end of the support member.
[0008] The staining rack is mounted on a rotating shaft, and the staining rack has a sample placement chamber in its circumferential direction; the support has a staining solution tank, which is located below the staining rack, and the staining rack is at least partially located inside the staining solution tank;
[0009] The dyeing rack has a through hole, and the dye bath is connected to the chamber through the through hole.
[0010] In one embodiment, the staining rack includes a first support plate, a second support plate, and a sample container. The first support plate and the second support plate are respectively sleeved on both ends of the rotating shaft, and the first support plate and the second support plate are arranged opposite to each other. Both the first support plate and the second support plate are circular in shape. The two ends of the sample container are detachably engaged with the first support plate and the second support plate, respectively.
[0011] The sample container has a chamber for placing the sample, and the through hole is formed on the sample container.
[0012] In one embodiment, the sample container includes a shell and two support arms, which are respectively installed at both ends of the shell. The first support plate and the second support plate have circumferential grooves, and the two support arms are respectively used to engage with the grooves of the first support plate and the second support plate.
[0013] The through hole extends from the inside of the housing to the outside of the housing, and the support arm has an opening that communicates with the chamber.
[0014] In one embodiment, the through holes are multiple and are distributed in a matrix along the length of the outer shell.
[0015] In one embodiment, the diameter of the through hole is 2 to 10 millimeters.
[0016] In one embodiment, the sample containers are multiple, and the first support plate and the second support plate have multiple slots in their circumference. The slots of the first support plate correspond to the slots of the second support plate, and the multiple sample containers are distributed along the circumference of the first support plate and the second support plate.
[0017] In one embodiment, the support includes a first base, a second base, and a base, wherein the first base and the second base are respectively installed at both ends of the base, and a U-shaped structure is formed between the first base, the second base, and the base.
[0018] The drive assembly is installed in the first seat, one end of the rotating shaft is rotatably connected to the second seat, and the staining rack is located between the first seat and the second seat.
[0019] In one embodiment, the drive assembly includes a motor, a reducer, and a coupling. The motor and the reducer are both mounted in a first housing. The first end of the reducer is mounted to the output end of the motor. The first end of the coupling is mounted to the second end of the reducer, and the second end of the coupling is mounted on a rotating shaft.
[0020] This utility model also proposes a temperature control device, including a box, a sealing door, a heating element, and a dyeing mechanism as described above. The sealing door is fitted with the box, the heating element is installed inside the box, and the dyeing mechanism is movably disposed inside the box.
[0021] In one embodiment, the temperature control device further includes a dye solution container, a connecting pipe, and a shut-off valve. The dye solution container is installed on the housing.

[0022] The technical solution provided by this utility model has the following advantages and effects:
[0023] As the staining rack rotates, the sample is immersed in the staining liquid. As the rack continues to rotate, the sample is separated from the staining liquid, preventing it from remaining continuously immersed. Each rotation of the rack results in one contact between the sample and the staining liquid. The frequency of this contact can be set based on the rotational speed of the shaft. This method simulates the frequency of tooth contact with saliva in the oral cavity, allowing the tooth sample to mimic this frequency. Using this staining method, the stained sample is then used in a brushing experiment to determine the whitening effect of the toothpaste. Attached Figure Description

[0032] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.
[0033] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.
[0034] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.
[0035] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.
[0036] This utility model proposes a dyeing mechanism 100, such as Figures 1 to 3 As shown, it includes: a drive assembly, a support 1, a rotating shaft 2, and a staining rack 3. The drive assembly is mounted on the first end of the support 1, the first end of the rotating shaft 2 is mounted on the output end of the drive assembly, and the second end of the rotating shaft 2 is rotatably disposed on the second end of the support 1. The staining rack 3 is mounted on the rotating shaft 2, and the staining rack 3 has a chamber for placing samples in its circumferential direction. The support 1 has a staining solution tank 41, which is disposed below the staining rack 3, and the staining rack 3 is at least partially disposed in the staining solution tank 41. The staining rack 3 has a through hole 333, and the staining solution tank 41 communicates with the chamber through the through hole 333.
[0037] Specifically, the sample is placed in the chamber of the staining rack 3, and the sample can be arranged circumferentially around the staining rack 3. When the drive assembly drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the staining rack 3 to rotate, and the staining rack 3 is at least partially located in the dye bath 41, which contains staining liquid. When the sample is in the dye bath 41, the staining liquid enters the chamber through the through hole 333 and comes into contact with the sample, thereby realizing the staining operation on the sample. Preferably, the sample is a tooth model, such as a tooth made of cow horn.
[0038] As the staining rack 3 rotates, the sample is immersed in the staining liquid. As the rack continues to rotate, the sample separates from the staining liquid, preventing it from remaining continuously immersed. Each rotation of the rack ensures the sample comes into contact with the staining liquid once. The frequency of this contact can be set based on the rotational speed of the shaft 2. This allows the contact frequency to be simulated by the frequency of tooth contact with saliva in the oral cavity, mimicking the normal frequency of tooth contact. Using this staining method, the stained sample is then used in a brushing experiment to determine the whitening effect of the toothpaste.
[0039] In some embodiments, such as Figure 1 As shown, the staining rack 3 includes a first support plate 31, a second support plate 32, and a sample container 33. The first support plate 31 and the second support plate 32 are respectively sleeved on both ends of the rotating shaft 2, and the first support plate 31 and the second support plate 32 are arranged opposite to each other. Both the first support plate 31 and the second support plate 32 are circular in shape. The two ends of the sample container 33 are detachably engaged with the first support plate 31 and the second support plate 32, respectively. The sample container 33 has a chamber for placing samples, and a through hole 333 is opened on the sample container 33. Specifically, the first support plate 31 and the second support plate 32 are used to fix on the rotating shaft 2, and the first support plate 31 and the second support plate 32 are used to support the two ends of the sample container 33. The first support plate 31 and the second support plate 32 can be set to be circular, so that the sample container 33 can be distributed in the circumference of the first support plate 31 and the second support plate 32. Multiple samples can be fixed in the chamber of the sample container 33. When the multiple samples are rotated, any sample is located in the dye bath 41. The dyeing liquid enters into the chamber through the through hole 333 to achieve intermittent contact with the sample, further simulating the staining of the sample in the oral cavity.
[0040] Furthermore, the two ends of the sample container 33 are detachably connected to the first support plate 31 and the second support plate 32, respectively. When placing the sample, the sample container 33 is detached from the first support plate 31 and the second support plate 32. After the sample container 33 is filled with the sample, the two ends of the sample container 33 are fixed to the first support plate 31 and the second support plate 32, respectively.
[0041] Preferred, such as Figure 2 and Figure 3As shown, the sample container 33 includes a shell 331 and two support arms 332, which are respectively installed at both ends of the shell 331. The first support plate 31 and the second support plate 32 have circumferential grooves 311, and the two support arms 332 are respectively used to engage with the grooves 311 of the first support plate 31 and the second support plate 32. A through hole 333 extends from the inside of the shell 331 to the outside of the shell 331. The support arms 332 have openings 334 that communicate with the chamber. Specifically, a tooth sample is inserted into the chamber through the two openings 334 of the sample container 33 and engages with the grooves 311 of the first support plate 31 and the second support plate 32 through the two support arms 332. When the chamber is full of sample, the openings 334 can be sealed with rubber stoppers to improve the stability of the sample within the chamber. Preferably, the diameter of the through hole 333 is 2 to 10 mm. In terms of sample size setting, the width or length of the sample can be greater than the diameter of the through hole 333 to prevent the sample from falling out of the through hole 333 and to prevent the sample from being soaked in the dye bath 41.
[0042] Preferred, such as Figure 2 and Figure 3 As shown, there are multiple through holes 333, which are distributed in a matrix along the length of the outer shell 331. Specifically, the multiple through holes 333 arranged in this way can ensure that the tooth samples in the chamber can all come into contact with the staining liquid in the staining bath 41, thus satisfying the requirement for staining multiple samples along the axial direction of the rotating shaft 2.
[0043] Preferred, such as Figure 1 As shown, there are multiple sample containers 33. The first support plate 31 and the second support plate 32 have multiple slots 311 circumferentially. The slots 311 of the first support plate 31 correspond to the slots 311 of the second support plate 32. The multiple sample containers 33 are distributed circumferentially along the first support plate 31 and the second support plate 32. Specifically, among the multiple slots 311, two slots 311 opposite each other axially on the rotating shaft 2 can be used to hold one sample container 33. The multiple slots 311 are distributed circumferentially on the first support plate 31 and the second support plate 32. Preferably, they can be equidistant, allowing multiple sample containers 33 to be arranged circumferentially on the first support plate 31 and the second support plate 32. Adjacent sample containers 33 can be arranged parallel to each other. When the rotating shaft 2 rotates, the multiple sample containers 33 contact the dyeing liquid in the dye bath 41 one by one, realizing the dyeing operation of large batches of samples and further improving dyeing efficiency.
[0044] Preferred, such as Figure 1As shown, the support member 1 includes a first base 11, a second base 13, and a base 12. The first base 11 and the second base 13 are respectively installed at both ends of the base 12, and a U-shaped structure is formed between the first base 11, the second base 13, and the base 12. The drive assembly is installed inside the first base 11, and one end of the rotating shaft 2 is rotatably connected to the second base 13. The dyeing rack 3 is located between the first base 11 and the second base 13. The first base 11 is used to support or fix the drive assembly, the second base 13 is used to support one end of the rotating shaft 2, and the base 12 is used to connect the first base 11 and the second base 13, thereby improving the overall stability of the support member 1.
[0045] In some embodiments, the dyeing mechanism 100 further includes a dyeing basin 4, which is placed on the base 12 and located below the dyeing rack 3. A dyeing tank 41 is formed inside the dyeing basin 4, so that there is no need to open the dyeing tank 41 on the base 12. When cleaning is required, the dyeing basin 4 can be removed from the base 12 to facilitate cleaning of the dyeing tank 41.
[0046] Preferably, the drive assembly includes a motor, a reducer, and a coupling 5. Both the motor and reducer are mounted within the first housing 11. The first end of the reducer is mounted to the output end of the motor (not shown in the figure), the first end of the coupling 5 is mounted to the second end of the reducer, and the second end of the coupling 5 is mounted on the rotating shaft 2. Specifically, the motor provides power to drive the rotating shaft 2 to rotate, while the reducer adjusts the rotational speed of the rotating shaft 2, thereby controlling the contact frequency between the sample and the staining liquid on the staining rack 3. The coupling 5 connects to the rotating shaft 2, serving as a mechanical component to connect two shafts (driving shaft and driven shaft) in different mechanisms, allowing them to rotate together to transmit torque. In high-speed, heavy-load power transmission, the coupling 5 also provides buffering, vibration damping, and improved dynamic performance of the shaft system. In this embodiment, the connection relationship between the motor, reducer, and coupling 5 in the drive assembly is a conventional technical means. The drive assembly can be purchased commercially, and other power systems can also drive the rotating shaft 2 to rotate; no particular limitation is made here.
[0047] This utility model also proposes a temperature control device 200, such as... Figure 4 As shown, the system includes a housing 201, a sealed door 202, a heating element (not shown), and a staining mechanism 100 as described above. The sealed door 202 cooperates with the housing 201, the heating element is installed inside the housing 201, and the staining mechanism 100 is movably disposed inside the housing 201. Specifically, the staining mechanism 100 is placed inside a sealed temperature control device 200. The heating element heats the staining liquid, causing it to evaporate and keeping the temperature control device 200 in a humid state. The temperature generated by the heating element creates a humid and hot environment inside the housing 201, simulating the temperature and environment of the sample in the oral cavity, further improving the realism of the sample staining operation.
[0048] Preferably, the temperature control device 200 further includes a dyeing solution container 203, a connecting pipe 204, and a shut-off valve 205. The dyeing solution container 203 is installed on the housing 201. The first end of the connecting pipe 204 is connected to the dyeing solution container 203, and the second end of the connecting pipe 204 is connected to the dyeing solution tank 41 of the dyeing mechanism 100. The shut-off valve 205 is installed on the connecting pipe 204. Specifically, when the heating element heats, the dyeing liquid evaporates in the dyeing solution tank 41, reducing the amount of dyeing liquid. By placing the dyeing solution container 203 on the housing 201, connecting the dyeing solution container 203 to the dyeing solution tank 41 via the connecting pipe 204, and controlling the flow through the shut-off valve 205, the dyeing liquid in the dyeing solution container 203 can be transported to the dyeing solution tank 41, thus replenishing the dyeing liquid in the dyeing solution tank 41 inside the housing 201 from outside the housing 201.
