Detailed Implementation
[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] To simplify the fixing structure between the treatment head and the handle, and to avoid an unstable fixing structure, this utility model provides a treatment device, such as... Figure 1 As shown, it includes:
[0036] First elastic element 10;
[0037] Treatment head 20, the treatment head 20 includes a connecting part 21;
[0038] The handle 30 includes a housing 31 and a mounting portion 32. The connecting portion 21 is adapted to be inserted into the mounting portion 32 in a first direction so that the mounting portion 32 is sleeved on the connecting portion 21.
[0039] The first stop portion, the first elastic member 10 is located on one of the handle 30 and the treatment head 20, and the first stop portion is located on the other of the handle 30 and the treatment head 20. When the connecting portion 21 is inserted into the mounting portion 32, the first elastic member 10 can deform and cooperate with the first stop portion to limit the movement of the treatment head 20 relative to the handle 30 in the first direction.
[0040] In the above technical solution, the outer shell 31 and the mounting part 32 are first assembled, then the connecting part 21 is inserted into the mounting part 32, and then the treatment head 20 and the handle 30 are fixed by the cooperation of the first elastic member 10 and the first stop. This solution uses the setting of the first elastic member 10 and the first stop to fix the treatment head 20 and the handle 30, thus simplifying the fixing structure between the treatment head 20 and the handle 30. At the same time, due to the setting of the first elastic member 10, the fixing structure between the treatment head 20 and the handle 30 is more solid.
[0041] In one specific embodiment, the first elastic element 10 is located on the handle 30, and the first stop is located on the treatment head 20. The first elastic element 10 has an elastically switchable protruding state and a retracted state. During the assembly of the treatment head 20 and the handle 30, the first stop on the treatment head 20 presses against the first elastic element 10, causing it to switch from the protruding state to the retracted state. After the treatment head 20 and the handle 30 are in place, the first elastic element 10, based on elastic deformation, switches from the retracted state to the protruding state, thus locking and fixing the treatment head 20 and the handle 30, preventing the treatment head 20 from moving relative to the handle 30 along a first direction. In this embodiment, the first direction is the axial direction of the handle 30. Figure 1 As shown. Furthermore, if it is necessary to disassemble the treatment head 20 and the handle 30, firstly, the first elastic element 10 and the handle 30 are separated, thereby allowing the first stop on the treatment head 20 to release the elastic clamping force provided by the first elastic element 10 based on the protruding state, allowing the treatment head 20 to move along the first direction, thus separating the treatment head 20 and the handle 30 (i.e., disassembly is complete). In another specific embodiment, the first elastic element 10 is located on the treatment head 20, and the first stop is located on the handle 30. The first elastic element 10 has an elastically switchable protruding state and a retracted state. During the assembly of the treatment head 20 and the handle 30, the first stop on the handle 30 presses against the first elastic element 10, causing it to switch from the protruding state to the retracted state. After the treatment head 20 and the handle 30 are installed in place, the first elastic element 10 switches from the retracted state to the protruding state based on elastic deformation, clamping and fixing the treatment head 20 and the handle 30 to prevent the treatment head 20 from moving relative to the handle 30 along the first direction. In this embodiment, the first direction is the axial direction of the handle 30. Figure 1 As shown. In addition, if it is necessary to disassemble the treatment head 20 and the handle 30, firstly separate the first elastic member 10 from the treatment head 20, so that the first stop on the handle 30 can release the elastic clamping force provided by the first elastic member 10 based on the protruding state, allowing the handle 30 to move in the first direction, so that the treatment head 20 and the handle 30 can be separated (i.e., disassembly is completed).
[0042] In one specific embodiment, the first stop is a protrusion, with one of the protrusion and the first elastic member 10 located on the connecting part 21 and the other on the mounting part 32. The following example illustrates this with the protrusion on the connecting part 21 and the first elastic member 10 on the mounting part 32. During assembly, as the connecting part 21 is inserted into the mounting part 32 along the first direction, the bottom surface of the protrusion first abuts against the first elastic member 10. After abutment, the first elastic member 10 undergoes elastic deformation, retracting to allow the connecting part 21 to insert along the first direction. Once the connecting part 21 is fully inserted, the first elastic member 10, located on the top surface of the protrusion, returns to its protruding state, locking the treatment head 20 and the handle 30 in place. Of course, if the protrusion is on the mounting part 32 and the first elastic member 10 is on the connecting part 21, the fixing principle for the treatment head 20 and the handle 30 is the same, and will not be elaborated upon here.
[0043] In another specific embodiment, such as Figure 2 and Figure 3 As shown, the first stop portion includes a first groove 22 located on the connecting portion 21. An opening 33 is provided on the mounting portion 32. A first elastic member 10 is located between the outer shell 31 and the mounting portion 32, and at least partially exposed in the opening 33. The first elastic member 10 is used to cooperate with the first groove 22 for stopping. In this technical solution, the first elastic member 10 exposed in the opening 33 and the first groove 22 serve as a limiting fit. During the installation of the treatment head 20 and the handle 30, the first elastic member 10 exposed in the opening 33 switches from a protruding state to a retracted state. After the treatment head 20 and the handle 30 are installed in place, the first elastic member 10 switches from a retracted state to a protruding state based on elastic deformation, thus locking the treatment head 20 and the handle 30. Preferably, the middle end of the first elastic member 10 is exposed within the opening 33. Figure 5 and Figure 6 A schematic diagram showing the treatment head 20 and handle 30 after assembly.
[0044] To optimize the above technical solution and further ensure the stability of the fixing structure between the treatment head 20 and the handle 30 after they are installed in place, and to prevent shaking, as follows: Figure 5 and Figure 6As shown, there are two openings 33, and the number of first grooves 22 matches the number of openings 33. The first elastic member 10 is U-shaped and is sleeved on the outside of the mounting part 32, with its two ends located in the two openings 33 respectively. Specifically, the two openings 33 and the two first grooves 22 are symmetrically arranged. By using the two ends of the U-shaped first elastic member 10 to cooperate with the corresponding openings 33 and the corresponding first grooves 22 respectively, the treatment head 20 and the handle 30 are fixed. At the same time, the symmetrical arrangement of the openings 33 and the first grooves 22 ensures that the fixed treatment head 20 and handle 30 are subjected to balanced forces and are not easily dislodged.
[0045] Optimize the above technical solutions, such as Figure 6 As shown, the first groove 22 is a tapered groove (the tapering direction is from the outside of the treatment head 20 radially toward its inside), and the opening 33 is a tapered opening (the tapering direction is from the outside of the handle 30 radially toward its inside). This design facilitates the assembly and fixation of the first elastic element 10 and allows the treatment head 20 to be easily inserted and removed without affecting its fixation strength.
[0046] In one of the alternative technical solutions, such as Figure 2 and Figure 4 As shown, to further secure the treatment head 20 and handle 30 and prevent them from wobbling, the handle 30 also includes a bracket 34 and a hook structure 35. The hook structure 35 is rotatably connected to the bracket 34. A second stop 23, which cooperates with the hook structure 35, is provided on the connecting part 21. The hook structure 35 is used to limit the engagement with the second stop 23. The hook structure 35 can rotate in the second direction to lock and unlock the treatment head 20 and handle 30. In use, after the treatment head 20 and handle 30 are secured by the first elastic member 10 and the first stop, when it is necessary to lock the treatment head 20 and handle 30, the hook structure 35 rotates counterclockwise in the second direction. After rotation to the desired position, the hook structure 35 engages with the second stop 23 to achieve the locking purpose. Figure 7 and Figure 8 As shown. When it is necessary to unlock the treatment head 20 and the handle 30, the latch structure 35 rotates clockwise in the second direction. After rotating a certain angle, the unlocking is achieved. The locked treatment head 20 and handle 30 are as follows: Figure 7 and Figure 8 As shown.
[0047] In one of the alternative technical solutions, such as Figure 4As shown, the handle 30 also includes a second elastic element 36, which is connected to both the bracket 34 and the hook structure 35. The second elastic element 36 is used to reset the hook structure 35 after it has moved. In this technical solution, the second elastic element 36 ensures that the hook structure 35 automatically resets after it has moved. Furthermore, preferably, the second elastic element 36 is a compression spring, which is a durable and inexpensive industrial product.
[0048] In one of the alternative technical solutions, such as Figure 2 and Figure 4 As shown, the handle 30 includes a button 37, and a corresponding opening 311 is provided on the housing 31. The button 37 is located in the opening 311 and can move along the axial direction of the opening 311. The first end of the latch structure 35 is used to engage with the second stop 23, and the second end of the latch structure 35 is used to abut against the button 37. In use, pressing the button 37 (at this time, the button 37 is displaced from the initial position to the pressed position) controls the first end of the latch structure 35 to engage with the second stop 23 through the second end of the latch structure 35, thereby locking the treatment head 20 and the handle 30. When the button 37 returns to the initial position from the pressed position, the first end of the latch structure 35 is controlled to disengage from the second stop 23 through the second end of the latch structure 35, thereby unlocking the treatment head 20 and the handle 30.
[0049] Optimize the above technical solutions, such as Figure 4 As shown, the handle 30 also includes a third elastic element 38, which is connected to the bracket 34 and the button 37 respectively. The third elastic element 38 is used to reset the button 37 after it has been moved. In this technical solution, the third elastic element 38 allows the button 37 to automatically return to its initial position from the pressed position, so as to complete the locking and unlocking of the treatment head 20 and the handle 30.
[0050] In one of the alternative technical solutions, such as Figure 4 As shown, the handle 30 also includes a top block 39. A third groove 341 is formed on the bracket 34. The top block 39 is slidably disposed within the third groove 341. A third elastic member 38 is disposed between the bottom surfaces of the top block 39 and the third groove 341. The side of the top block 39 facing away from the third elastic member 38 protrudes to form a protrusion 391, which is used for assembly with the button 37. In this technical solution, the third groove 341 can guide the top block 39, ensuring that the button 37 always moves along the axial direction of the third groove 341 during pressing and resetting. Preferably, there are two third elastic members 38, symmetrically arranged within the third groove 341 to provide sufficient elastic restoring force.
[0051] In one of the alternative technical solutions, such as Figure 4As shown, the bracket 34 has a fourth groove 342. The hook structure 35 includes a rotating shaft 351, which is located in the fourth groove 342. The hook structure 35 is used to rotate relative to the bracket 34 via the rotating shaft 351 and the fourth groove 342. In this technical solution, the rotating shaft 351 supports the rotation, allowing the hook structure 35 to rotate relative to the rotating shaft 351. Preferably, the extending direction of the rotating shaft 351 is arranged at a 90-degree angle to the axial direction of the hook structure 35.
[0052] To optimize the above technical solution, the handle 30 further includes a hook-and-press plate 310; the bracket 34 is provided with a fixing part that cooperates with the hook-and-press plate 310, and the hook-and-press plate 310 is used to restrict the rotating shaft 351 to be located in the fourth groove 342. In this technical solution, when in use, after the hook-and-press plate 310 restricts the rotating shaft 351 in the fourth groove 342, it is then fixed with the fixing part. The hook-and-press plate 310 is provided to achieve the pressing of the hook structure 35; specifically, there are two hook-and-press plates 310, and there are also two corresponding fixing parts. One hook-and-press plate 310 is used to restrict one end of the rotating shaft 351 in the fourth groove 342, and the other hook-and-press plate 310 is also used to restrict the other end of the rotating shaft 351 in the fourth groove 342. Preferably, the hook-and-press plate 310 and the fixing part are detachably connected.
