A cosmetic brush, its water-guiding structure, and its water-guiding core Technical Field
[0001] This invention relates to the technical field of cosmetic brushes, and particularly to a cosmetic brush, its water-guiding structure, and its water-guiding core. Background Technology
[0002] Makeup brushes are tools used for applying makeup, and they come in various types and have different uses. They are typically used to draw and modify facial features, such as lips, eyelids, and eyebrows. One type of makeup brush is the TANK brush, which uses a liquid formula and employs capillary action, where a core acts as a guide for the liquid. Specifically, one end of the core contacts the liquid in the brush barrel, and the other end contacts the brush tip. This allows the liquid to be guided from the barrel to the tip, enabling the brush to be used to draw on the skin. However, with advancements in technology, to enhance the appearance of the makeup, pearlescent powder is often added to the liquid. This pearlescent powder can easily clog the core, preventing the liquid or pearlescent powder from reaching the brush tip properly. Summary of the Invention

In a preferred embodiment of the present invention, the inner diameter of the connecting section is larger than the inner diameter of the water inlet section, and the thickness of the second protrusion is smaller than the depth of the second water inlet channel, thereby avoiding interference of the second protrusion with the flow of liquid.
[0024] The second objective of this invention is to provide a water-guiding structure for a cosmetic pen. By setting up water-guiding groove one and water-guiding groove two, liquid containing pearlescent powder can move along water-guiding groove one and water-guiding groove two from one end of the water-guiding core to the other end until the pen tip, thereby avoiding clogging. Thus, it solves the problem that liquid containing pearlescent powder can easily cause clogging of the water-guiding core.
[0025] The second objective of this invention is achieved as follows:
[0026] The water-guiding structure for a cosmetic pen includes a water-guiding core and a diverter seat. The diverter seat has a channel in the middle, and the inner wall of the channel is provided with several protrusions. A water-guiding groove is provided between two adjacent protrusions.
[0027] The water-guiding core includes a connecting post and a connecting part disposed on the connecting post. The connecting part is used to connect with the pen tip, and the connecting part has a second water-guiding channel corresponding to the first water-guiding channel. The connecting post is located in the channel to prevent the first water-guiding channels from communicating with each other.
[0028] Preferably, the channel includes a water intake section and a connecting section, and the water intake section is provided with a first protrusion and a first water intake groove, and the inner wall of the connecting section is provided with a plurality of second protrusions. The bottom of the connecting part abuts against the first protrusion, and the second protrusions are staggered with the first protrusion and located in the second water intake groove.
[0029] Preferably, the inner diameter of the connecting section is larger than the inner diameter of the water intake section, and the thickness of the second protrusion is smaller than the depth of the second water intake channel.
[0030] Preferably, the connecting part has a gathering part at one end near the pen tip, and the connecting part has a plurality of protruding strips three on the outer side below the gathering part, and a water channel two is provided between two adjacent protruding strips three.
[0031] Preferably, the third protrusion includes a gathering section and an installation section, and the installation section is located in the channel and abuts against the first protrusion. The thickness of the gathering section is less than the thickness of the installation section and gradually decreases towards the pen tip.
[0032] Preferably, the flow divider seat has several flow divider plates on its outer side, and a groove is provided between two adjacent flow divider plates. The flow divider seat also has a channel rail for connecting the several grooves and a side opening for connecting the channel rail and the channel.
[0033] Preferably, it also includes a pen barrel, and the pen barrel is provided with an inner rod, one end of which is located inside the pen barrel and is provided with a tail plug, and the other end of which is provided with a pen tip, a water guide core is provided between the pen tip and the inner rod, a diverter seat is provided between the water guide core and the inner rod, and a pen tip sleeve is provided between the pen tip and the inner rod.
[0034] Preferably, it also includes a cap and an inner rod disposed on the pen barrel, and a pen tip is disposed on the inner rod, and a water inlet is disposed between the pen tip and the inner rod, and a diverter is disposed between the water inlet and the inner rod;
[0035] The cap is fitted onto the outer side of the top of the inner rod, and the cap contains a movable inner cap. The pen tip is located inside the inner cap, and a spring is provided between the inner cap and the cap, so that the inner side of the inner cap fits against the outer side of the inner rod through the spring.
[0036] The outstanding and beneficial technical effects of the water-guiding structure for cosmetic brushes of the present invention compared with the prior art are:
[0037] By placing the connecting post inside the channel, the connection between the water inlet channels is prevented, thus making each water inlet channel independent. Through the arrangement of water inlet channels one and two, the liquid containing pearlescent powder can move from one end of the water inlet core to the other end and to the pen tip along water inlet channels one and two, thereby avoiding clogging.
[0038] The third objective of this invention is to provide a water-guiding core. By setting a connecting column, the structure of the lower end of the water-guiding core is simplified. At the same time, the setting of the gathering part and the variation of the thickness of the protrusion make the water-guiding core not a column, but a pointed one, which facilitates the insertion with the pen tip. Secondly, the setting of the water-guiding groove allows the liquid containing pearl powder to move along the water-guiding groove to the pen tip, thereby avoiding clogging. Thus, it solves the problem of unstable connection of the water-guiding core as a column and is adapted to the diverter seat with water-guiding function and liquid containing pearl powder.
[0039] The third objective of this invention is achieved as follows:
[0040] A water-conducting core includes a connecting post and a connecting portion disposed on the connecting post, the connecting portion being used to connect to a pen tip:

The thickness of the protruding strips gradually decreases in the direction away from the connecting post.
[0042] Preferably, the connecting part has a plurality of protruding strips 2 on the outer side below the protruding strip 1, and the protruding strips 2 correspond one-to-one with the protruding strip 1, and a water inlet trough 2 communicating with the water inlet trough 1 is provided between two adjacent protruding strips 2.
[0043] Preferably, the thickness of the second protrusion is greater than the thickness of the first protrusion, and the outer side of the top of the second protrusion is formed with a bevel.
[0044] Preferably, the horizontal cross-sectional area of the gathering portion gradually decreases in the direction away from the connecting column, and the gathering portion is planar at the end away from the connecting column.
[0045] Preferably, the protrusion includes a gathering section and a connecting section, and the thickness of the gathering section is less than the thickness of the connecting section and gradually decreases in the direction away from the connecting post.
[0046] Preferably, the horizontal cross-sectional area of the connecting column is greater than the horizontal cross-sectional area of the central column of the connecting part.
[0047] The outstanding and beneficial technical effects of the water-guiding core of the present invention compared with the prior art are:
[0048] The design of the connecting post simplifies the structure of the lower end of the water inlet core. The design of the gathering part and the variation in the thickness of the protrusion make the water inlet core not a column, but a pointed one, which facilitates the insertion with the pen tip. Secondly, the design of the water inlet channel allows the liquid containing pearlescent powder to move along the water inlet channel to the pen tip, thus avoiding clogging.

Detailed Implementation
[0064] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0065] As shown in Figures 1-10, a cosmetic pen includes a pen barrel 1 and a cap 2 disposed at one end of the pen barrel 1. A pen tip 3 is disposed inside the cap 2 at the end of the pen barrel 1, and a water guide core 4 is disposed between the pen tip 3 and the pen barrel 1. A diverter seat 5 is sleeved on the outside of the water guide core 4.
[0066] Meanwhile, a channel 51 is provided in the middle of the diverter seat 5, and a number of protrusions 52 are provided on the inner wall of the channel 51. A water inlet groove 53 is provided between two adjacent protrusions 52. The water inlet core 4 includes a connecting post 41 and a connecting part 42 provided on the connecting post 41. The connecting part 42 is used to connect with the pen tip 3. A water inlet groove 43 is provided on the connecting part 42 corresponding to the water inlet groove 53. The connecting post 41 is located in the channel 51 to avoid communication between the water inlets 53.
[0067] Therefore, in actual use, the connection post 41 is located in the channel 51 to avoid communication between the water inlet troughs 53, so that each water inlet trough 53 is independent. Through the arrangement of water inlet troughs 53 and water inlet trough 43, the liquid with pearlescent powder can move from one end of the water inlet core 4 to the other end and to the pen tip 3 along the water inlet troughs 53 and water inlet 43, thus avoiding clogging.
[0068] The widths of the openings of the first water inlet 53, the first protrusion 52, and the second water inlet 43 can all be adjusted according to actual conditions to accommodate liquids of different concentrations. Similarly, the depths of the first and second water inlets 53 and 43 can also be adjusted to accommodate liquids of different concentrations. Furthermore, the water inlet core 4 and the pen tip 3 are connected by an insert, and the shape of the water inlet core 4 can be varied, not limited to the shape shown in the attached diagram. That is, the connecting post 41 and the connecting part 42 can be integrally formed or separately assembled. The shapes of the first water inlet 53 and the first protrusion 52 are not limited to straight lines; other shapes are possible, but straight lines are preferred because they are easier to process.
[0069] As shown in Figures 7-9, the channel 51 includes a water intake section 512 and a connecting section 511. The inner wall of the water intake section 512 is provided with a first protrusion 52 and a first water intake channel 53. The inner wall of the connecting section 511 is provided with a plurality of second protrusions 56. The bottom of the connecting part 42 abuts against the first protrusion 52, and the second protrusions 56 are staggered with the first protrusion 52 and located in the second water intake channel 43.
[0070] Therefore, in actual use, by placing the connecting post 41 inside the channel 51 and abutting the bottom of the connecting part 42 against the first protrusion 52, the second protrusion 56 is adapted to the second water inlet channel 43, thereby realizing the connection between the water inlet core 4 and the diverter seat 5.
[0071] Furthermore, the protrusion 56 prevents relative rotation between the water inlet core 4 and the diverter seat 5, thus avoiding mismatch between the water inlet channel 56 and the water inlet channel 43. The bottom of the connecting part 42 abuts against the protrusion 52, thereby limiting the height position.
[0072] Meanwhile, to avoid interference with the flow of liquid caused by the second protrusion 56, the inner diameter of the connecting section 511 is set to be larger than the inner diameter of the water inlet section 512, and the thickness of the second protrusion 56 is set to be smaller than the depth of the water inlet channel 43.
[0073] As shown in Figure 10, the structure of the connecting part 42 is as follows: First, the connecting part 42 has a gathering part 47 at one end near the pen tip 3, and the horizontal cross-sectional area of the gathering part 47 gradually decreases towards the pen tip 3, thus facilitating insertion with the pen tip 3. Moreover, the structure of the second water channel 43 is as follows: First, the connecting part 42 has several protruding strips 44 on the outer side below the gathering part 47, and the second water channel 43 is provided between two adjacent protruding strips 44.
[0074] Meanwhile, the structure of the protrusion 3 44 is as follows: First, the protrusion 3 44 includes a gathering section 45 and an installation section 46, and the installation section 46 is located in the channel 51 and abuts against the protrusion 1 52. The thickness of the gathering section 45 is less than the thickness of the installation section 46 and gradually decreases towards the pen tip 3.
[0075] As shown in Figures 7-9, the structure of the diversion seat 5 is as follows: First, several diversion plates 57 are provided on the outside of the diversion seat 5, and a groove 58 is provided between two adjacent diversion plates 57. The diversion seat 5 is provided with a groove rail 59 for connecting several grooves 58, and the diversion seat 5 is provided with a side opening 55 for connecting the groove rail 59 and the channel 51.
[0076] The side opening 55 is used for the flow of liquid and gas, thereby balancing the air pressure inside and outside the flow divider 5 and allowing the liquid to be divided along the flow divider plate 57. In addition, the flow divider 5 is also provided with a second groove 50, which is used to connect several grooves 58. The second groove 50 is adapted to the grooves 58 and the first groove 59 to better balance the air pressure inside and outside the flow divider 5 and to divide the flow.
[0077] As shown in Figures 2-4, the pen barrel 1 has the following structure: First, an inner rod 6 is provided on the pen barrel 1, and one end of the inner rod 6 is located inside the pen barrel 1 and is provided with a tail plug 7. The other end of the inner rod 6 is provided with a pen tip 3, and a water guide core 4 is provided between the pen tip 3 and the inner rod 6.
[0078] Meanwhile, the structure between the inner rod 6 and the pen barrel 1 is as follows: First, a convex ring 61 and a convex edge 62 are provided on the outer side of the inner rod 6, and the bottom of the convex edge 62 abuts against the top of the pen barrel 1, and a slot 11 is opened on the inner wall of the pen barrel 1 corresponding to the convex ring 61.
[0079] Furthermore, the structure between the inner rod 6 and the diverter seat 5 is as follows: First, the inner wall of the inner rod 6 is provided with a step 63 and a convex ring 64, and the bottom of the diverter seat 5 abuts against the convex ring 64. Additionally, the outer side of the diverter seat 5 is provided with a protrusion 54, and the top of the protrusion 54 abuts against the step 63.
[0080] Therefore, in actual use, the position of the diverter seat 5 is limited by the setting of step 63 and convex ring 64.
[0081] Furthermore, a pen tip sleeve 8 is provided between the pen tip 3 and the inner rod 6, and the pen tip sleeve 8 is fitted on the outside of the pen tip 3, with the bottom of the pen tip sleeve 8 fitted on the top outside of the diverter seat 5. Therefore, in actual use, the pen tip sleeve 8 is used to connect the pen tip 3 and the diverter seat 5, thereby stabilizing the connection between the pen tip 3 and the water inlet core 4.
[0082] The pen tip sleeve 8 has a side groove 81 on the outside to facilitate the flow of gas and thus balance the air pressure inside and outside the inner rod 6.
[0083] As shown in Figures 2-4, the structure of the cover 2 is as follows: First, an inner rod 6 is provided on the pen barrel 1, and one end of the inner rod 6 is located inside the cover 2 and is provided with a pen tip 3. A water guide core 4 is provided between the pen tip 3 and the inner rod 6.
[0084] Meanwhile, the cover 2 has a movable inner cover 9 inside, and the pen tip 3 is located inside the inner cover 9. A spring 10 is provided between the inner cover 9 and the cover 2. The spring 10 makes the inner side of the inner cover 9 fit with the outer side of the inner rod 6, thereby ensuring the stability and sealing of the connection.
[0085] The range of movement of the inner cover 9 is as follows: First, the inner wall of the cover 2 is provided with a protrusion 21, and the outer side of the inner cover 9 is provided with a protrusion 91 and a protrusion 92 respectively, and the protrusion 21 is located between the protrusion 91 and the protrusion 92 and moves between the protrusion 91 and the protrusion 92.
[0086] Furthermore, the structure between the cover 2 and the inner rod 6 is as follows: First, a convex ring 65 is provided on the outer side of the inner rod 6, and a slot 22 is provided on the inner wall of the cover 2 corresponding to the convex ring 65. The structure of the spring 10 is as follows: First, a mounting part 94 is provided on the top of the inner cover 9, and the spring 10 is sleeved on the outer side of the mounting part 94.
[0087] The following is a detailed description of an embodiment of the water-guiding structure of the present invention for a cosmetic brush.
[0088] The water-guiding structure for a cosmetic pen includes a water-guiding core 4 and a diverter seat 5. A channel 51 is provided in the middle of the diverter seat 5, and a number of protrusions 52 are provided on the inner wall of the channel 51. A water-guiding groove 53 is provided between two adjacent protrusions 52.
[0089] Meanwhile, the water-guiding core 4 includes a connecting post 41 and a connecting part 42 disposed on the connecting post 41. The connecting part 42 is used to connect with the pen tip 3. The connecting part 42 is provided with a second water-guiding groove 43 corresponding to the first water-guiding groove 53. The connecting post 41 is located in the channel 51 to avoid communication between the first water-guiding grooves 53.
[0090] Therefore, in actual use, the connection post 41 is located in the channel 51 to avoid communication between the water inlet troughs 53, so that each water inlet trough 53 is independent. Through the arrangement of water inlet troughs 53 and water inlet trough 43, the liquid with pearlescent powder can move from one end of the water inlet core 4 to the other end and to the pen tip 3 along the water inlet troughs 53 and water inlet 43, thus avoiding clogging.
[0091] The widths of the openings of the first water inlet 53, the first protrusion 52, and the second water inlet 43 can all be adjusted according to actual conditions to accommodate liquids of different concentrations. Similarly, the depths of the first and second water inlets 53 and 43 can also be adjusted to accommodate liquids of different concentrations. Furthermore, the water inlet core 4 and the pen tip 3 are connected by an insert, and the shape of the water inlet core 4 can be varied, not limited to the shape shown in the attached diagram. That is, the connecting post 41 and the connecting part 42 can be integrally formed or separately assembled. The shapes of the first water inlet 53 and the first protrusion 52 are not limited to straight lines; other shapes are possible, but straight lines are preferred because they are easier to process.
[0092] The channel 51 includes a water intake section 512 and a connecting section 511. The inner wall of the water intake section 512 is provided with a first protrusion 52 and a first water intake channel 53. The inner wall of the connecting section 511 is provided with a plurality of second protrusions 56. The bottom of the connecting part 42 abuts against the first protrusion 52. The second protrusions 56 are staggered with the first protrusion 52 and located in the second water intake channel 43.
[0093] Therefore, in actual use, by placing the connecting post 41 inside the channel 51 and abutting the bottom of the connecting part 42 against the first protrusion 52, the second protrusion 56 is adapted to the second water inlet channel 43, thereby realizing the connection between the water inlet core 4 and the diverter seat 5.
[0094] Furthermore, the protrusion 56 prevents relative rotation between the water inlet core 4 and the diverter seat 5, thus avoiding mismatch between the water inlet channel 56 and the water inlet channel 43. The bottom of the connecting part 42 abuts against the protrusion 52, thereby limiting the height position.
[0095] Meanwhile, to avoid interference with the flow of liquid caused by the second protrusion 56, the inner diameter of the connecting section 511 is set to be larger than the inner diameter of the water inlet section 512, and the thickness of the second protrusion 56 is set to be smaller than the depth of the water inlet channel 43.
[0096] The structure of the connecting part 42 is as follows: First, the connecting part 42 has a gathering part 47 at one end near the pen tip 3, and the horizontal cross-sectional area of the gathering part 47 gradually decreases towards the pen tip 3, thereby facilitating insertion with the pen tip 3. Moreover, the structure of the second water channel 43 is as follows: First, the connecting part 42 has several protruding strips 44 on the outer side below the gathering part 47, and the second water channel 43 is provided between two adjacent protruding strips 44.
[0097] Meanwhile, the structure of the protrusion 3 44 is as follows: First, the protrusion 3 44 includes a gathering section 45 and an installation section 46, and the installation section 46 is located in the channel 51 and abuts against the protrusion 1 52. The thickness of the gathering section 45 is less than the thickness of the installation section 46 and gradually decreases towards the pen tip 3.
[0098] The structure of the diversion seat 5 is as follows: First, several diversion plates 57 are provided on the outside of the diversion seat 5, and a groove 58 is provided between two adjacent diversion plates 57. The diversion seat 5 is provided with a groove rail 59 for connecting several grooves 58, and the diversion seat 5 is provided with a side opening 55 for connecting the groove rail 59 and the channel 51.
[0099] The side opening 55 is used for the flow of liquid and gas, thereby balancing the air pressure inside and outside the flow divider 5 and allowing the liquid to be divided along the flow divider plate 57. In addition, the flow divider 5 is also provided with a second groove 50, which is used to connect several grooves 58. The second groove 50 is adapted to the grooves 58 and the first groove 59 to better balance the air pressure inside and outside the flow divider 5 and to divide the flow.
[0100] It also includes a pen barrel 1, and an inner rod 6 is provided on the pen barrel 1. One end of the inner rod 6 is located inside the pen barrel 1 and is provided with a tail plug 7.

Furthermore, the outer side of the diverter seat 5 is provided with a protrusion 54, and the top of the protrusion 54 abuts against the step 63.
[0103] Therefore, in actual use, the position of the diverter seat 5 is limited by the setting of step 63 and convex ring 64.
[0104] Secondly, the pen tip sleeve 8 is fitted onto the outside of the pen tip 3, and the bottom of the pen tip sleeve 8 is fitted onto the top outside of the diverter seat 5. Therefore, in actual use, the pen tip sleeve 8 is used to connect the pen tip 3 and the diverter seat 5, thereby stabilizing the connection between the pen tip 3 and the water inlet core 4.
[0105] Furthermore, a side groove 81 is provided on the outer side of the pen tip cap 8 to facilitate the flow of gas and thus balance the air pressure inside and outside the inner rod 6.
[0106] It also includes a cover 2 and an inner rod 6 disposed on the pen barrel 1, and a pen tip 3 is disposed on the inner rod 6, and a water guide core 4 is disposed between the pen tip 3 and the inner rod 6, and a diverter seat 5 is disposed between the water guide core 4 and the inner rod 6.
[0107] Meanwhile, the cover 2 is fitted on the outer side of the top of the inner rod 6, and the cover 2 has a movable inner cover 9 inside. The pen tip 3 is located inside the inner cover 9, and a spring 10 is provided between the inner cover 9 and the cover 2. The spring 10 makes the inner side of the inner cover 9 fit with the outer side of the inner rod 6, thereby ensuring the stability and sealing of the connection.
[0108] The range of movement of the inner cover 9 is as follows: First, the inner wall of the cover 2 is provided with a protrusion 21, and the outer side of the inner cover 9 is provided with a protrusion 91 and a protrusion 92 respectively, and the protrusion 21 is located between the protrusion 91 and the protrusion 92 and moves between the protrusion 91 and the protrusion 92.
[0109] Furthermore, the structure between the cover 2 and the inner rod 6 is as follows: First, a convex ring 65 is provided on the outer side of the inner rod 6, and a slot 22 is provided on the inner wall of the cover 2 corresponding to the convex ring 65. The structure of the spring 10 is as follows: First, a mounting part 94 is provided on the top of the inner cover 9, and the spring 10 is sleeved on the outer side of the mounting part 94.
[0110] An embodiment of the water-drawing core of the present invention will be described in detail below with reference to Figures 11-14.
[0111] As shown in Figures 11-14, a water-guiding core includes a connecting post 11 and a connecting part 12 disposed on the connecting post 11, and the connecting part 12 is used to connect with the pen tip.
[0112] Meanwhile, the connecting part 12 is provided with a gathering part 121 at the end away from the connecting post 11, and the connecting part 12 is provided with a number of protrusions 122 on the outer side below the gathering part 121, and a water channel 123 is provided between two adjacent protrusions 122, and the thickness of the protrusions 122 gradually decreases in the direction away from the connecting post 11.
[0113] Therefore, in actual use, the structure of the lower end of the water-guiding core is simplified by setting the connecting column 11. At the same time, the setting of the gathering part 121 and the change of the thickness of the protrusion 122 result in the water-guiding core not being a column, but having a pointed tip, which facilitates the insertion with the pen tip. Secondly, the setting of the water-guiding groove 123 allows the liquid with pearlescent powder to move along the water-guiding groove 123 to the pen tip, thereby avoiding clogging.
[0114] The structure of the connecting part 12 is as follows: First, the connecting part 12 has several protrusions 124 on the outer side below the protrusion 122, and the protrusions 124 correspond one-to-one with the protrusion 122. A water channel 125 communicating with the water channel 123 is provided between two adjacent protrusions 124.
[0115] Therefore, in actual use, the main purpose of the second protrusion 124 and the second water channel 125 is to connect the water core and the diversion seat and to make the water core and the diversion seat correspond. Moreover, the second water channel 125 is used to match the protrusion on the diversion seat, thereby restricting the relative rotation between the diversion seat and the water core.
[0116] Meanwhile, the thickness of the second protrusion 124 is greater than the thickness of the first protrusion 122, and the top outer side of the second protrusion 124 is formed with a bevel.
[0117] Therefore, in actual use, the design with different thicknesses and the bevel design increases the contact area between the pen tip and the pen tip, thus making the connection more stable.
[0118] Furthermore, the protrusion 122 includes a gathering section 126 and a connecting section 127, and the thickness of the gathering section 126 is less than the thickness of the connecting section 127 and gradually decreases in the direction away from the connecting post 11.
[0119] Therefore, in actual use, the different thicknesses increase the contact area between the pen tip and the pen tip, thus making the connection more stable.
[0120] Secondly, the horizontal cross-sectional area of the gathering part gradually decreases in the direction away from the connecting column 11, and the gathering part 121 is a plane at the end away from the connecting column 11.
[0121] Therefore, in actual use, the flat surface design avoids sharp corners or points, thus preventing scratches.
[0122] Furthermore, the horizontal cross-sectional area of the connecting column 11 must be greater than the horizontal cross-sectional area of the central column of the connecting part 12. The central column refers to the portion remaining after removing components such as the protruding strip 122. The overall shape of the water-conducting core can also be varied, not limited to the appearance shown in the attached diagram. The width of the water-conducting channel opening and the width of the protruding strip can be adjusted according to actual conditions to accommodate liquids of different concentrations. The depth of the water-conducting channel can also be adjusted according to actual conditions to accommodate liquids of different concentrations.

However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
