[0041] Example 1:

[0042] like Figures 1 to 4 As shown, the control handle includes a handle body 1, a button assembly 2, a control assembly 3, and a seal 4. The handle body 1 has an inner cavity 11 and a button hole 12 communicating with the inner cavity 11. The button assembly 2 includes a control button 21 and a button lever 22. The button lever 22 is connected to the control button 21 and extends into the inner cavity 11 through the button hole 12. The control button 21 can be raised, lowered, and rotated relative to the handle body 1. The control assembly 3 includes an encoder 31, which is disposed in the inner cavity 11 and connected to the button lever 22. The seal 4 is disposed on the handle body 1 and / or the button assembly 2 to prevent external fluid from entering the inner cavity 11 through the button hole 12.

[0043] The control handle is connected to the encoder 31 of the control assembly 3 through the key rod 22, and when control is needed, the circumferential rotation of the key rod 22 can be driven by rotating the control knob 21, or the axial movement of the key rod 22 can be driven by pressing the key rod 22, so that different motion signals can be given to the encoder 31, and a plurality of key instructions can be combined through different combinations of the two actions, so that a plurality of control modes can be combined through the two actions of pressing and rotating the key, and control is facilitated.

[0044] As shown in Figure 2 , the handle body 1 also has a retaining ring 13, which is arranged around the outer periphery of the key hole 12 to enclose it. The control knob 21 is grooved, and the key rod 22 is connected to the bottom of the groove. The control knob 21 is buckled onto the retaining ring 13, so that the key rod 22 extends into the inner cavity 11 through the key hole 12 to connect the encoder 31. The control knob 21 can be lifted and rotated relative to the retaining ring 13. The inner groove wall of the control knob 21 is provided with a dustproof rubber layer 5, which isolates the inner groove wall of the control knob 21 from the outer side wall of the retaining ring 13, preventing external debris from entering the gap between the two, and the dustproof rubber layer 5 can also isolate part of the fluid.

[0045] Further, as shown in Figure 2 and Figure 4 , in the current embodiment, the control knob 21 is also provided with a limiting ring 23, which is arranged at the bottom of the groove of the control knob 21. The key rod 22 is located in the ring of the limiting ring 23. The limiting ring 23 is inserted together with the key rod 22 through the key hole 12. The sealing element 4 seals the gap between the limiting ring 23 and the retaining ring 13. Since the dustproof rubber layer 5 cannot isolate all fluids, the fluid is isolated at the sealing element 4, preventing the fluid from entering the inner cavity 11 through the key hole 12, and protecting the control assembly 3 and the like in the inner cavity 11. In the current embodiment, the sealing element 4 is an IPX7 sealing ring. Illustratively, the limiting ring 23 is provided with a plurality of embedding grooves 26 in the direction of entering and exiting the key hole 12, and the sealing element 4 is embedded in the embedding grooves 26; or the retaining ring 13 is provided with a plurality of embedding grooves 26 in the direction of entering and exiting the key hole 12, and the sealing element 4 is arranged on the retaining ring 13; or both have embedding grooves 26 and sealing elements 4.

[0046] It should be noted here that since the encoder 31 is provided with a potshaped piece, it can accumulate part of the potential energy when the control knob 21 is pressed. The encoder 31 can be a shaft type encoder 31 or a shaft sleeve type encoder 31, both of which are prior art and will not be described further. That is, the restoring force of the control knob 21 can be provided by the encoder 31 itself when it is pressed. Continue as Figure 2As shown, since the control knob 21 is buckled on the retaining ring 13, in order to avoid the control knob 21 from being separated from the handle body 1, the limiting ring 23 is provided with a first limiting groove 24, the first limiting groove 24 is arranged along the circumference of the limiting ring 23, the hole wall of the keyhole 12 is embedded in the first limiting groove 24, that is, the handle body 1 forming the hole wall of the keyhole 12 is embedded in the first limiting groove 24, the groove width of the first limiting groove 24 along the direction of the keyhole 12 is greater than the hole wall depth of the keyhole 12, so that the hole wall part of the keyhole 12 can move in the first limiting groove 24, providing stroke space for pressing and recovering; further, the groove wall of the first limiting groove 24 can limit the pressing distance of the control knob 21 by abutting against the handle body 1, which can avoid excessive pressing on one hand, and avoid the control knob 21 from being separated on the other hand.

[0047] As shown in the figure, Figure 1 In addition, in the current embodiment, the control assembly 3 also includes a control board 32 (PCB board) connected to the encoder 31, the control board 32 is arranged in the inner cavity 11, and the control board 32 is connected to the motor and the driving shaft and other components in the inner cavity 11.

[0048] In the current embodiment, the control knob 21 is provided with a rotary scale, so that the rotary angle of the control knob 21 can be timely limited through the rotary scale, so that different control modes can be formed according to different rotary angles, and the control is more intuitive.

In the current embodiment, the second limiting groove 25 is arranged along the circumference of the key lever 22, further avoiding interfering with the rotation of the key lever 22.

[0051] In the current embodiment, the sealing element 4 seals the gap between the key lever 22 and the hole wall of the keyhole 12, and the sealing element 4 can still adopt the IPX7 sealing ring. Similarly, a embedding groove 26 can be arranged on the key lever 22 and / or the hole wall of the keyhole 12 to accommodate the sealing element 4, which will not be described in detail.

[0052] Further, as shown in the figure, Figure 6As shown, the metal ring 7 is embedded in the key hole 12, the key rod 22 is a metal rod, the key rod 22 penetrates the metal ring 7, and the sealing element 4 is arranged between the key rod 22 and the inner wall of the metal ring 7, so that by embedding the metal ring 7 in the key hole 12, the strength of the overall structure is improved, the deformation of the key rod 22 and the inner wall of the key hole 12 after long-term use is avoided, and the accuracy of control is ensured. When the metal ring 7 is arranged, the snap spring 8 is arranged on the metal ring 7; for example, the metal ring 7 is provided with a mounting groove 27, and the snap spring 8 is fixed in the mounting groove 27.

[0053] Continue as Figure 6 As shown, in the current embodiment, the elastic element 6 is arranged between the retaining ring 13 and the key hole 12, the elastic element 6 can be stretched and contracted in the direction of entering and exiting the key hole 12, one end of the elastic element 6 is connected to the control knob 21 or the handle body 1, so that the compressible distance of the elastic element 6 adjusts the force of the control knob 21 pressing the encoder 31, so as to avoid over-pressing the encoder 31 as much as possible, and prolong the service life thereof; and the elastic element 6 is connected to the control knob 21 or the handle body 1 at only one end, so as to avoid hindering the rotation of the control knob 21. For example, the elastic element 6 is a spring, and the spring is sleeved on the key rod 22.
