Description

Technical Field

[0001] This application relates to the field of viscosity measuring equipment, and more particularly to a rotational viscosity measuring device. Background Technology

[0002] Viscosity is one of the important physicochemical indicators of e-cigarette atomizing fluids. The viscosity directly affects the performance of the atomizing fluid; for example, too high a viscosity can reduce the fluid's flowability, potentially leading to poor wicking within the device, while too low a viscosity may cause leakage. Atomizing fluids with appropriate viscosity can provide a better taste and throat hit. Therefore, measuring the viscosity of atomizing fluids is crucial.

[0003] In related technologies, a rotational viscometer is generally used to determine the viscosity of the atomizing liquid. After the test is completed, the outer cylinder containing the atomizing liquid needs to be cleaned. Because the open outer cylinder has a certain depth, it is easy for cleaning to be incomplete. Incomplete cleaning will result in residual liquid droplets on the base of the outer cylinder, and the residual liquid will affect the viscosity measurement of the next atomizing liquid.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0038] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0039] To address the technical problem in existing rotary viscometers where inadequate cleaning of the outer cylinder can lead to residual liquid, affecting subsequent viscosity measurements of the atomized liquid, this application provides a rotary viscosity measuring device that enables convenient cleaning, improves cleaning efficiency, avoids residual liquid, and ensures that no residual liquid will affect the next viscosity measurement.

[0040] Figures 1 to 3 A rotational viscosity measuring device provided in this application includes a support 1, a rotor suspended on the support 1, and a liquid storage container 4 for containing the liquid to be tested. The liquid storage container 4 includes a sleeve 41 and a base 42. The sleeve 41 has openings at both ends, and the base 42 is detachably connected to the bottom end of the sleeve 41 to form a receiving cavity 4A for containing the liquid to be tested.

[0041] It is understood that the bracket 1 provides an installation position for the rotor. The rotor can be inserted into the receiving cavity 4A of the liquid storage container 4 from the top of the sleeve 41 to measure the viscosity of the liquid to be tested in the receiving cavity 4A. After the viscosity test is completed, the liquid in the receiving cavity 4A is poured out, and then the liquid storage container 4 is cleaned. In this application, the liquid storage container 4 includes a sleeve 41 and a base 42, and the sleeve 41 and the base 42 are detachably connected. Thus, when cleaning the liquid storage container 4, the sleeve 41 and the base 42 can be separated for separate cleaning. The separated base 42 and sleeve 41 are easy to clean and can improve the cleaning effect of the sleeve 41 and the base 42, avoiding liquid residue in the sleeve 41 and the base 42, and ensuring that no residual liquid will affect the next viscosity measurement.

[0042] Rotational viscosity measuring devices can detect viscosity through the rotational method, which is a method to determine fluid viscosity by measuring the viscous torque generated by the interaction between the fluid and the object or the rotational hysteresis of the object.

[0043] For example, the rotor can be a rigid object such as a cylinder, cone, sphere, or pointer.

[0044] When the rotational viscosity measuring device is working, the liquid storage container 4 contains the liquid to be tested, and the rotor is inserted into the receiving cavity 4A from the open end of the sleeve 41. The rotor can be rotated by a motor to drive the liquid to be tested to rotate. Due to the viscosity of the liquid, the rotation of the rotor is delayed. This delay can be converted into the torque of another component (the hairspring). The viscosity is calculated by detecting this delay.

[0045] It should be noted that the connection method of the rotor, motor and hairspring in the rotational viscosity measuring device can adopt a known structure, and this application does not improve the rotational viscosity measuring method.

[0046] like Figure 1 As shown, in some embodiments of this application, the rotational viscosity measuring device further includes a mounting base 3, which is located below the rotor; the mounting base 3 has a mounting groove 3A on the side facing the rotor; the liquid storage container 4 is detachably installed in the mounting groove 3A; wherein, the outer wall of the sleeve 41 abuts against the side wall of the mounting groove 3A, and the base 42 abuts against the bottom wall of the mounting groove 3A.

[0047] Understandably, the mounting slot 3A of the mounting base 3 is adapted to the shape of the liquid storage container 4. The mounting slot 3A is used to place the liquid storage container 4, providing installation positioning for it. Furthermore, the mounting base 3 improves the positional stability of the liquid storage container 4, preventing leakage caused by it being knocked over. The mounting base 3 is placed on an external workbench or on the support 1. During viscosity measurement, neither the mounting base 3 nor the liquid storage container 4 rotates. After the viscosity measurement is completed, the liquid storage container is removed, the liquid inside is poured out, and then the container can be cleaned.

[0048] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the sleeve 41 is cylindrical, and the inner wall surface of the bottom end of the sleeve 41 is provided with internal threads; the base 42 is provided with external threads, and the base 42 and the sleeve 41 are connected by internal and external thread engagement.

[0049] It is understandable that the sleeve 41 and the base 42 are detachably connected by a threaded connection, which is simple in structure, easy to disassemble and stable in connection.

[0050] In some other embodiments of this application, the bottom end of the sleeve 41 and the base 42 can also be detachably connected by an interference fit. In this case, the base 42 is inserted into the sleeve 41 from the bottom end of the sleeve 41. To improve the sealing performance, a sealing ring is fitted on the part of the base 42 inserted into the sleeve 41. The sealing ring is squeezed by the outside of the base 42 and the inner wall of the sleeve 41 to form an interference fit.

[0051] When cleaning the liquid storage container 4, the sealing ring can be cleaned for reuse. Of course, the sealing ring can also be replaced each time a viscosity measurement is performed.

[0052] like Figure 3 As shown, in some embodiments of this application, the base 42 includes a base body 421 and a connecting boss 422. The base body 421 is cylindrical and abuts against the bottom end of the sleeve 41. The connecting boss 422 is located on the side of the base body 421 facing the sleeve 41 and has an external thread. The connecting boss 422 is inserted into the sleeve 41 and threadedly connected to the sleeve 41. Thus, the connection between the base 42 and the sleeve 41 is achieved through the threaded connection between the connecting boss 422 and the sleeve 41. The base body 421 is located outside the sleeve 41 and can provide a force application point so that rotating the base body 421 can drive the connecting boss 422 to rotate, thereby assembling and disassembling the base 42 and the sleeve 41. During the assembly process, when the base body 421 abuts against the bottom end of the sleeve 41, it indicates that the base 42 and the sleeve 41 are assembled in place.

[0053] To improve the sealing performance of the sleeve 41 and the base 42, in some embodiments of this application, the sleeve 41 is provided with a sealing groove on the side facing the base body 421, and a sealing element is provided in the sealing groove. The sealing groove extends annularly along the axis surrounding the sleeve 41, and the sealing element is annular.

[0054] In some embodiments of this application, a sealing groove is provided on the side of the base body 421 facing the sleeve 41; a sealing element is provided in the sealing groove. The sealing groove extends in a ring along the axis surrounding the sleeve 41 to form a ring, and the sealing element is ring-shaped.

[0055] In some embodiments of this application, a sealing groove is provided on the side of the sleeve 41 facing the base body 421, and a sealing groove is also provided on the side of the base body 421 facing the sleeve 41. The sealing grooves on the sleeve 41 and the sealing grooves on the base body 421 can be correspondingly arranged and are also spaced apart; a sealing element is provided in the sealing groove. The sealing groove extends in a ring along the direction surrounding the axis of the sleeve 41 to form a ring, and the sealing element is ring-shaped.

[0056] like Figure 1 As shown, in some embodiments of this application, the rotational viscosity measuring device further includes a control box 21. The control box 21 is mounted on the support 1, located above the liquid storage container 4, and connected to the rotor. The control box 21 can provide a human-machine interface. It is understood that the control box 21 can automate viscosity measurement and analysis.

[0057] like Figure 1 As shown, in some embodiments of this application, the bracket 1 includes a support member 11 and an assembly 12. The support member 11 is used to support an external workbench, the assembly 12 is connected to the support member 11 and has a certain height, and the control box 21 is disposed on the assembly 12.

[0058] Understandably, the support member 11 provides support for the assembly 12. The support member 11 and the assembly 12 can be connected integrally or fixed by threaded connection. The assembly 12 provides an installation position for the control box 21 so that the control box 21 has a certain height, allowing the control box 21 and the rotor to be located above the mounting base 3.

[0059] In some embodiments, a horizontal adjustment nut may be provided at the bottom of the support 11, which can be adjusted by the horizontal adjustment thread to achieve "leveling" and eliminate the influence of the bracket 1 or the worktable on the viscosity measurement results.

[0060] In some embodiments, the control box 21 is connected to the bracket 1 via an adjusting seat, allowing the position of the control box 21 on the bracket 1 to be adjusted, thereby adjusting the rotor position. Before viscosity measurement begins, the control box 21 is moved downwards to insert the rotor into the receiving cavity 4A of the liquid storage container 4. After viscosity measurement is completed, the control box 21 is moved upwards to disengage the rotor from the receiving cavity 4A, facilitating subsequent cleaning of the liquid storage container 4.

[0061] In one embodiment, the assembly 12 is provided with a rack, the length of which extends along the height of the assembly 12; the adjusting seat includes a fixing member, a locking member, an adjusting gear, and an adjusting member; the control box 21 is connected to the fixing member; the adjusting member is rotatably connected to the fixing member and is connected to the adjusting gear, which meshes with the rack; the locking member is threadedly connected to the fixing member. The locking member can move to abut against or move away from the assembly 12 to lock or unlock the fixing member and the assembly 12. The axial direction of the locking member is perpendicular to the axial direction of the assembly 12. In other embodiments, the connection between the assembly 12 and the control box 21 is not limited to the rack and gear engagement method; it can also be replaced by a slide rail and slider engagement method, etc.

[0062] When the rotor height needs to be adjusted, rotate the locking member to move it away from the assembly 12, thus unlocking the fixing member from the assembly 12. Then, rotate the adjusting member to drive the adjusting gear. As the adjusting gear rotates, it moves along the length of the rack, thereby raising or lowering the adjusting seat and control box 21 as a whole. When the control box 21 is adjusted to the appropriate position, rotate the locking member to abut against the assembly 12, thus fixing the adjusting seat onto the assembly 12.

[0063] In some embodiments of this application, the rotational viscosity measuring device further includes a temperature control component, which is disposed on the mounting base 3; the temperature control component is used to adjust the temperature of the liquid to be tested in the receiving cavity 4A.

[0064] Understandably, the temperature control component can be used to adjust the temperature of the liquid to be tested in the storage container 4, enabling automated temperature adjustment, accurate temperature control, and improved measurement efficiency.

[0065] It should be noted that the temperature control component is electrically connected to the control box 21, and the operation of the temperature control component can be achieved through the control box 21.

[0066] In some embodiments of this application, the temperature control component includes a heating element disposed on the wall of the mounting groove 3A and abutting against the outer wall of the sleeve 41. Thus, by controlling the heating power of the heating element, the liquid to be tested in the storage container 4 can be adjusted to the required temperature, and can be adjusted to different temperatures according to different needs.

[0067] In some embodiments of this application, the rotational viscosity measuring device further includes a display electrically connected to the control box 21; the display is configured to display the detected viscosity value.

[0068] The display can not only show the detected viscosity value for easy and intuitive display of measurement results, but also display other operation instructions in the viscosity detection process. The display can enable human-machine interaction between the control box 21 and the operator, making operation convenient and realizing automation and intelligence.
