Description

Technical Field

[0001] This utility model relates to the technical field of thermos cup cleaning equipment, and in particular to a device for cleaning the inner wall of a thermos cup. Background Technology

[0002] Over time, insulated cups often accumulate limescale, tea stains, and other grime on their inner walls. These stains not only affect the cup's appearance but can also breed bacteria, posing a potential health threat to the user. However, due to the small opening and elongated inner cavity of insulated cups, traditional manual cleaning methods often fail to thoroughly remove these stains, making cleaning quite inconvenient.

[0003] The applicant disclosed a thermos cup cleaning device in patent publication number CN220344344U, including a base, a first driving assembly, at least two slider assemblies, at least two scissor assemblies, and at least two cleaning strips; the two scissor assemblies are disposed on both sides of the base, and the two cleaning strips are mounted on the two scissor assemblies; the scissor assembly includes a first link, a second link, a third link, and a fourth link, the two ends of the cleaning strips are respectively hinged to one end of the first link and the second link, the middle part of the first link and the middle part of the second link are coaxial and rotatably sleeved on the slider assembly, the ends of the first link and the second link away from the cleaning strips are respectively hinged to one end of the third link and the fourth link, and the other ends of the third link and the fourth link are coaxially hinged to the base; the first driving assembly is used to drive the slider assembly to move in a first direction, so that the two scissor assemblies can drive the two cleaning strips to move away from or towards each other.

[0004] As can be seen from the patent above, although this thermos cup cleaning device can effectively improve the cleaning efficiency of thermos cups by using two cleaning strips and does not require continuous manual application of large force, thus reducing labor intensity, the applicant found in subsequent production and use that the two cleaning strips need to be moved closer or further apart by two scissor assemblies. The scissor assembly has a relatively complex structural design, which not only increases the manufacturing cost but also makes it inconvenient to disassemble and assemble, reducing production efficiency. Furthermore, one end of the first link and the second link in the scissor assembly are respectively hinged to the two ends of the cleaning strip, making it difficult for the cleaning strip to clean the bottom of the thermos cup, thus reducing the reliability and convenience of use. Utility Model Content

[0005] The main purpose of this utility model is to provide a device for cleaning the inner wall of a thermos cup, which aims to solve the problems of existing thermos cup cleaning devices having complex structural designs, which not only increase manufacturing costs, but also make it inconvenient to disassemble and assemble, reducing production efficiency, and making it difficult to clean the bottom of the thermos cup, thus reducing reliability and convenience of use.

[0006] To achieve the above objectives, this utility model provides a device for cleaning the inner wall of a thermos cup, including a handle, several scissor assemblies, and a cleaning strip. The several scissor assemblies are evenly and spaced along the circumference of the handle and are used to install the cleaning strip. Each of the several scissor assemblies includes a fixed seat, a movable seat, a first connecting rod, and a second connecting rod. The fixed seat is detachably installed at the end of the handle, and the movable seat is movably and limitably installed on the handle. One end of the first connecting rod and the second connecting rod are respectively hinged to the fixed seat and the movable seat, and the other end of the first connecting rod and the second connecting rod are both hinged to one end of the cleaning strip, so that the cleaning strip can be moved closer to or away from the handle through the first connecting rod and the second connecting rod.

[0007] Preferably, any of the scissor lift assemblies further includes a flexible connector, on the side of the flexible connector away from the handle member on which a cleaning strip is detachably mounted, and on the other side of the flexible connector near the top position, a lug is formed, and the ends of the first link and the second link away from the fixed seat and the movable seat are hinged to the lug.

[0008] Preferably, a boss is formed on the side of the movable seat away from the fixed seat, and a plurality of locking members are detachably installed on the outer wall of the boss, the plurality of locking members being evenly and spaced apart along the circumference of the handle.

[0009] Preferably, a flat surface is formed on the outer wall of the handle for the locking member to abut against.

[0010] Preferably, the handle has an adjustment groove along its extension direction, and a locking member passing through the adjustment groove is detachably installed on the movable seat.

[0029] Example 1:

[0030] This utility model proposes a device for cleaning the inner wall of a thermos cup.

[0031] In one embodiment of this utility model, a thermos cup inner wall cleaning device includes a handle 1, a plurality of scissor assemblies 2 and a cleaning strip 3. The plurality of scissor assemblies 2 are evenly and spaced along the circumference of the handle 1 and are used to install the cleaning strip 3. Each of the plurality of scissor assemblies 2 includes a fixed seat 4, a movable seat 5, a first connecting rod 6 and a second connecting rod 7. The fixed seat 4 is detachably installed at the end of the handle 1, and the movable seat 5 is movably and limitably installed on the handle 1. One end of the first connecting rod 6 and the second connecting rod 7 is hinged to the fixed seat 4 and the movable seat 5 respectively, and the other end of the first connecting rod 6 and the second connecting rod 7 is hinged to one end of a cleaning strip 3, so that the cleaning strip 3 can be moved closer to or away from the handle 1 by the first connecting rod 6 and the second connecting rod 7.

[0032] Specifically, if Figures 1 to 4 As shown, in the thermos cup inner wall cleaning device of this utility model, since several scissor assemblies 2 are evenly and spaced along the circumference of the handle 1 and cleaning strips 3 are installed, the user can hold the handle 1 and insert the cleaning strips 3 into the thermos cup to clean the stains on the inner wall of the thermos cup evenly and thoroughly. It is simple and convenient to use. Furthermore, since the fixed seat 4 in the scissor lift assembly 2 is detachably installed at the end of the handle 1, and the movable seat 5 is movably installed on the handle 1, the detachable installation of the fixed seat 4 and the handle 1 can be achieved by a threaded connection, which is convenient for disassembly and assembly. The movable installation of the movable seat 5 and the handle 1 can be achieved by a sliding snap-fit, that is, the movable seat 5 is sleeved on the handle 1 and can be fixed by a snap-fit ​​or other components. At the same time, since one end of the first connecting rod 6 and the second connecting rod 7 in the scissor lift assembly 2 is hinged to the fixed seat 4 and the movable seat 5 respectively, and the other end is hinged to the cleaning strip 3, when it is necessary to clean thermos cups of different sizes, the user can adjust the installation position of the movable seat 5 on the handle 1, so that the first connecting rod 6 and the second connecting rod 7 extend or retract relative to each other, thereby driving the corresponding cleaning strip 3 to move closer to or away from the handle 1, thus enabling the inner wall cleaning of thermos cups of various sizes, improving applicability and flexibility, and facilitating storage.

[0033] Understandably, in the actual manufacturing process of this thermos cup inner wall cleaning device, workers can sequentially install the movable seat 5, the second connecting rod 7, the fixed seat 4, and the first connecting rod 6 onto the handle 1, and hinge the ends of the first connecting rod 6 and the second connecting rod 7 away from the fixed seat 4 and the movable seat 5 to the cleaning strip 3, thereby completing the overall assembly of this utility model. Compared with the prior art, this utility model, while ensuring the cleaning of stains on the inner wall of the thermos cup, omits unnecessary connecting rods and other components, thus not only facilitating disassembly and assembly by workers and improving production efficiency. In addition, since both the first link 6 and the second link 7 are hinged to one end of the cleaning strip 3, the cleaning strip 3 can be made of plastic cleaning strips, rubber cleaning strips, etc. (the cleaning strip 3 can be selected according to the type of stains to be cleaned and the material of the inner wall of the thermos). When the bottom of the cup needs to be cleaned, the user continues to insert the handle 1 into the bottom of the cup so that the cleaning strip 3 is elastically deformed and bent. That is, the end of the cleaning strip 3 away from the first link 6 and the second link 7 gradually moves toward the handle 1. As the handle 1 is continuously inserted into the thermos, the fixing seat 4 on the end of the handle 1 can press down the ends of several cleaning strips 3. At this time, the user can rotate the handle 1 to clean the stains attached to the bottom of the cup, which not only expands the scope of use, but also improves the reliability and convenience of use.

[0034] In one embodiment, any scissor lift assembly 2 further includes a flexible connecting seat 8, on the side of the flexible connecting seat 8 away from the handle 1, a cleaning strip 3 is detachably mounted, and a lug is formed on the other side of the flexible connecting seat 8 near the top. The ends of the first connecting rod 6 and the second connecting rod 7 away from the fixed seat 4 and the movable seat 5 are hinged to the lug. Specifically, as Figures 1 to 4 As shown, the detachable installation method of the cleaning strip 3 and the flexible connecting seat 8 can be a sliding groove snap-fit, which facilitates the disassembly, replacement, and cleaning of the cleaning strip 3. Furthermore, the flexible connecting seat 8 can be made of materials such as plastic or rubber, as is currently available in the technology. This allows the flexible connecting seat 8 to elastically deform and bend under the pressure of the handle 1, thereby causing the cleaning strip 3 to bend synchronously, thus satisfying the cleaning operation of the cup bottom. Understandably, since the first connecting rod 6 and the second connecting rod 7 are hinged to the lugs on the flexible connecting seat 8, the movable seat 5 can move the flexible connecting seat 8 closer to or away from the handle 1 via the first connecting rod 6 and the second connecting rod 7 when sliding. This allows the cleaning strip 3 to adapt to various inner wall sizes of insulated cups, resulting in a simple and reasonable structural design.

[0035] In one embodiment, a boss 9 is formed on the side of the movable seat 5 away from the fixed seat 4. A plurality of locking members 10 are detachably mounted on the outer wall of the boss 9. The locking members 10 are evenly and spaced apart along the circumference of the handle member 1. Specifically, as shown... Figure 1 and Figure 4As shown, all locking elements 10 can be knobs as in the prior art, and the detachable installation method of the locking elements 10 and the boss 9 can be a threaded connection, allowing the user to adjust the installation position of the movable seat 5 on the outer wall of the handle 1 by turning the locking elements 10, which is simple and convenient to operate. Furthermore, since the locking elements 10 are evenly and spaced along the circumference of the handle 1, they can achieve multi-point limiting of the movable seat 5, preventing the movable seat 5 from rotating or moving when the user turns the handle 1, thus improving the installation stability of the movable seat 5.

[0036] In one embodiment, specifically, as Figure 1 , Figure 3 and Figure 4 As shown, a flat surface 11 is formed on the outer wall of the handle 1 for the locking member 10 to abut against, thereby increasing the contact area between the end face of the locking member 10 and the outer wall of the handle 1, and further improving the installation stability of the movable seat 5.

[0037] In another embodiment, the handle 1 has an adjustment groove along its extending direction, and a locking member 10 passing through the adjustment groove is detachably mounted on the movable seat 5. It can be understood that, as Figure 1 and Figure 4 As shown, the locking component 10 can be a bolt connection as in the prior art. That is, when the movable seat 5 is moved and adjusted to the position, the user can tighten the nut of the bolt connection (which can be a wing nut) to achieve the limiting and fixing of the movable seat 5. The structure is simple and easy to operate.

[0038] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, a sleeve 12 is detachably mounted on the end of the handle 1 away from the fixed base 4, and anti-slip textures are formed on the outer wall of the sleeve 12. Specifically, the detachable mounting method of the handle 1 and the sleeve 12 can be a threaded connection, which facilitates the disassembly and assembly of the sleeve 12; at the same time, the sleeve 12 makes it easier for the user to hold and rotate the handle 1, making operation more convenient. Furthermore, since the anti-slip textures are formed on the outer wall of the sleeve 12, the friction between the user's hand and the sleeve 12 is increased, which facilitates the rotation of the sleeve 12 and improves the user experience.

[0039] In another embodiment, the end of the handle 1 furthest from the fixed base 4 is connected to an external drive mechanism. Understandably, the external drive mechanism can be a motor or similar device found in the prior art, allowing the handle 1 to rotate under its influence. The user only needs to adjust the cleaning strips 3 according to the dimensions of the thermos's inner wall, without manually rotating the handle 1. This reduces the user's workload, makes it more convenient to use, improves the cleaning efficiency and effectiveness of the thermos's inner wall, and ensures reliable operation.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
