Technical Field

[0001] This utility model relates to the technical field of plasma cleaners, and more particularly to a handheld plasma cleaner. Background Technology

[0002] Plasma cleaners, also known as plasma cleaning machines or plasma surface treatment devices, are a new surface treatment technology that uses plasma to deeply clean the surface of objects. They can achieve results that conventional cleaning methods cannot. They are highly automated and do not create a damaging layer on the surface, ensuring surface quality and making them increasingly widely used in various industries.

[0003] Existing handheld plasma cleaners mainly consist of a plasma unit and a plasma nozzle. The plasma unit generates plasma, which is then ejected from the plasma nozzle to treat the surface of the workpiece. However, because the plasma nozzle of a handheld plasma cleaner is relatively heavy, operators are prone to fatigue after prolonged use, making it difficult to control the distance between the nozzle and the workpiece. This affects the cleaning effect and can easily lead to danger. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a handheld plasma cleaner that supports the plasma nozzle, assisting workers in holding the nozzle and reducing their workload, ensuring effective surface cleaning of workpieces, and improving safety during extended work periods.

[0006] Furthermore, a flexible hose is connected between the handheld nozzle and the plasma host, and several clamps are provided on the side of the auxiliary support arm, with the flexible hose being detachably installed inside the clamps.

[0007] Furthermore, the auxiliary support arm includes a mounting base fixedly installed on the top of the plasma host and a support rod assembly rotatably hinged to the mounting base, with the elastic clamp hinged to the end of the support rod assembly.

[0008] Furthermore, the support rod assembly includes at least two connecting rods, each connecting rod having a hinge seat rotatably mounted at both ends, and two adjacent connecting rods being hinged together through the hinge seats. The elastic clamp and the mounting base are rotatably connected to the hinge seats of the starting and ending connecting rods, respectively.

[0009] Furthermore, the connecting rod is a telescopic rod.

[0010] Furthermore, locking bolts for locking are provided at the hinge positions of two adjacent hinge seats.

[0011] Furthermore, the elastic clip has an opening on its side wall, and a sealing bolt for closing the opening is provided at the opening location.

[0012] Furthermore, the top of the handheld nozzle is provided with a mounting groove, and the elastic clip is engaged in the mounting groove.

[0013] Furthermore, the handheld nozzle has a nozzle at its bottom for ejecting plasma, and a gripping part is provided near the handheld nozzle, with a shielding part at the bottom of the gripping part for shielding.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model sets an auxiliary robotic arm on the plasma host and sets an elastic clamp at the end of the auxiliary robotic arm. At the same time, the handheld nozzle is detachably installed on the elastic clamp. When the operator cleans the surface of the workpiece, the handheld nozzle can be installed on the elastic clamp and supported by the auxiliary robotic arm, which can reduce the operator's hand burden and ensure the surface cleaning effect of the workpiece.

[0016] 2. This utility model improves the stability of the handheld nozzle when the user operates it for cleaning by setting an auxiliary robotic arm to install the nozzle, thereby further improving the cleaning effect of the workpiece.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 3 As shown, a handheld plasma cleaner includes a plasma unit 1 and a handheld nozzle 2. The operator can hold the handheld nozzle 2 and aim it at the workpiece, thereby cleaning the workpiece surface using plasma generated by the plasma unit 1. In this embodiment, the plasma unit 1 has an auxiliary support arm 3 on its top, which supports the handheld nozzle 2, assisting the operator in holding the nozzle and reducing workload, ensuring effective surface cleaning, and improving safety during extended work periods.

[0026] Specifically, such as Figure 2As shown, the auxiliary support arm 3 in this embodiment has an elastic clip 4 at its end. The handheld nozzle 2 is detachably installed in the elastic clip 4, allowing the worker to fix the handheld nozzle 2 to the auxiliary support arm 3 when cleaning the workpiece. This supports the handheld nozzle 2, effectively reducing the worker's grip pressure and fatigue from prolonged work, thus ensuring cleaning effectiveness. Simultaneously, the support arm 3 also improves the stability of the handheld nozzle 2, reducing vibration during operation and further enhancing cleaning efficiency while ensuring work safety. Furthermore, the auxiliary support arm 3 can fix the handheld nozzle 2 at a fixed height, allowing automatic cleaning of the workpiece surface after it passes through the nozzle. This facilitates automatic cleaning and enables both handheld and automatic working modes, providing a rich set of functions.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the elastic clip 4 in this embodiment has a cylindrical structure. A vertically arranged opening 41 is provided on the side wall of the elastic clip 4, allowing it to be disassembled into two parts. This facilitates the installation of the handheld nozzle 2 by engaging it through the opening 41. It also facilitates the installation and fixation of handheld nozzles 2 of various sizes, making it widely applicable. Furthermore, the top of the handheld nozzle 2 in this embodiment has a mounting groove 21. When the handheld nozzle 2 is installed on the auxiliary support arm 3, the elastic clip 4 can engage within the mounting groove 21, improving the stability of the handheld nozzle 2 installation.

[0028] Furthermore, to ensure the handheld nozzle 2 is stably installed within the elastic clip 4 and to prevent it from detaching during operation, this embodiment also includes a sealing bolt 42 that passes laterally through the opening 41 of the elastic clip 4. After the handheld nozzle 2 is installed into the elastic clip 4, the sealing bolt 42 can pass laterally through the opening 41 to close it, thus locking the two halves of the elastic clip 4 together and ensuring stable installation of the handheld nozzle 2. Specifically, the elastic clip 4 in this embodiment has a protruding connecting piece at the opening 41 with a connecting hole. The sealing bolt 42 passes through the connecting hole and is connected to the other side by a nut, thereby closing the opening 41. Additionally, both the sealing bolt 42 and the nut in this embodiment are butterfly-shaped, facilitating manual operation to close or open the opening 41, thus enabling the installation or removal of the handheld nozzle 2 without the need for tools, making operation convenient.

[0029] like Figures 1 to 2As shown, in this embodiment, the handheld nozzle 2 is mounted on the elastic clip 4, allowing the auxiliary support arm 3 to support the handheld nozzle 2 during operation. This reduces the burden on the operator's hands and improves the stability of the handheld nozzle 2 during cleaning, ensuring effective cleaning. The auxiliary support arm 3 in this embodiment includes a mounting base 31 fixedly mounted on the top of the plasma unit 1 and a support rod assembly 32 hinged to the mounting base 31. The elastic clip 4 is hinged to the end of the support rod assembly 32. After the handheld nozzle 2 is mounted on the elastic clip 4, the support rod assembly 32 can swing and adjust in any direction under the operator's control during cleaning, thus providing real-time support for the handheld nozzle 2. This reduces the operator's hand handling burden, ensures flexibility in handheld cleaning, and improves the overall stability of the handheld nozzle 2, thereby guaranteeing effective cleaning.

[0030] Specifically, such as Figure 2 As shown, the support rod assembly 32 includes at least two connecting rods 321, and in this embodiment, there are three. The two ends of the three connecting rods 321 are respectively rotatably mounted with hinge seats 322. Each connecting rod 321 is sequentially hinged through the hinge seats 322. The elastic clip 4 and the mounting base 31 are respectively connected to the hinge seats 322 of the connecting rods 321 located at both ends. When the user operates the handheld nozzle 2 mounted on the elastic clip 4 for cleaning, each connecting rod 321 can swing in any direction through the hinge seats 322, which realizes the convenience of the staff when cleaning.

[0031] Furthermore, the connecting rod 321 in this embodiment is a telescopic rod, which allows the support rod assembly 32 to extend its overall length through the telescopic rod, thereby expanding the overall swing range of the auxiliary support arm 3 in this embodiment and thus expanding the applicable scenarios of this embodiment.

[0032] To achieve stable support for the handheld nozzle 2, the connection between the connecting rod 321 and the hinge seat 322, as well as the connection between two adjacent hinge seats 322, has a certain degree of damping, thus ensuring the stability of the handheld nozzle 2 after it is mounted on the auxiliary support arm 3. Furthermore, in this embodiment, locking bolts 33 for adjusting the hinge tightness are provided at the hinge positions of two adjacent hinge seats 322, allowing the user to adjust the swing force according to their needs and to fix the handheld nozzle 2 using the locking bolts 33, thereby enabling automatic cleaning.

[0033] Specifically, in this embodiment, the locking bolt 33 passes laterally through the hinge positions of the two hinge seats 322. The other end of the locking bolt 33 is provided with a locking nut threadedly connected to it, allowing the two hinge seats 322 to be locked together via the locking bolt 33 and the locking nut, thus adjusting the damping force. Furthermore, both the locking bolt 33 and the locking nut in this embodiment are butterfly-shaped, facilitating manual adjustment by the operator.

[0034] like Figure 1 As shown, a flexible tube 5 for transmitting plasma is connected between the handheld nozzle 2 and the plasma generator 1. To prevent the flexible tube 5 connected to the handheld nozzle 2 from sagging after it is installed on the auxiliary support arm 3, which would affect plasma transmission and the normal operation of the handheld nozzle 2, this embodiment provides a clamp 6 on the side of the auxiliary support arm 3, specifically on the side wall of the hinge seat 322. When the operator uses the auxiliary support arm 3 to support the handheld nozzle 2, the flexible tube 5 connected to the handheld nozzle 2 can be installed on the clamp 6 on the surface of each hinge seat 322, allowing the flexible tube 5 to be arranged along the auxiliary support arm 3. This not only prevents the flexible tube 5 from sagging but also makes plasma transmission smoother. In addition, the flexible tube 5 in this embodiment is detachably installed in the clamp 6, allowing the operator to remove the flexible tube 5 from the clamp 6 after finishing work or when directly holding the handheld nozzle 2 for cleaning workpieces, thus preventing the auxiliary support arm 3 from jamming the tube and affecting normal operation.

[0035] like Figure 3 As shown, the handheld nozzle 2 in this embodiment has a nozzle for ejecting plasma at its bottom end, and a gripping part 22 is provided near the handheld nozzle 2 to facilitate the operation of the handheld nozzle 2 and improve the gripping comfort of the operator. In addition, the bottom end of the gripping part 22 in this embodiment is also provided with a shielding member 23 for shielding, which can prevent the operator from touching the plasma and causing injury.

[0036] In summary, the working principle of this embodiment is as follows: This embodiment sets an auxiliary robotic arm on the plasma host 1 and sets an elastic clamp 4 at the end of the auxiliary robotic arm. At the same time, the handheld nozzle 2 is detachably installed on the elastic clamp 4. When the worker cleans the surface of the workpiece to be cleaned, the handheld nozzle 2 can be installed on the elastic clamp 4 and supported by the auxiliary robotic arm, which can reduce the worker's hand burden and ensure the surface cleaning effect of the workpiece.

[0037] Furthermore, by installing an auxiliary robotic arm to install the handheld nozzle 2 in this embodiment, the stability of the user's operation of the handheld nozzle 2 during cleaning can be improved, thereby further enhancing the cleaning effect on the workpiece. In addition, the auxiliary robotic arm can also fix the handheld nozzle 2 at a certain height, which facilitates automatic cleaning.

[0038] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
