Description

Technical Field

[0001] The utility model relates to the technical field of knob screens, and in particular to a touch screen with a touch-controlled knob. Background Art

[0002] With the rapid development of the electrical appliance industry, knob screens are widely used in many products such as washing machines, microwave ovens, etc.

[0003] A knob screen device is proposed in the utility model patent with announcement number CN 213426130 U. The knob screen device includes: a transparent window, a display panel, a panel support frame, a rotating housing, a main board and a base, and the main board is provided with a Hall sensor, a magnet and a roller. Through the above method, the knob screen device can be made compact, easy to operate and responsive.

[0004] However, in actual use of the above case, since touch screens with touch knobs are usually used in equipment such as washing machines and coffee machines, and there is a certain gap between the touch screen and the rotating shell, during the use of the touch screen, external water vapor can easily enter the circuit elements inside the touch screen through the gap, which can easily cause a short circuit in the circuit elements. For this reason, the present application proposes a touch screen with a touch knob. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a touch screen with a touch knob to solve the problem that the existing touch screen with a touch knob is usually used in equipment such as washing machines and coffee machines, and there is a certain gap between the touch screen and the rotating shell, so that during the use of the touch screen, external water vapor can easily enter the circuit elements inside the touch screen through the gap, which can easily cause a short circuit in the circuit elements.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A touch screen with a touch knob comprises a mounting seat, wherein a touch screen body is mounted inside the mounting seat by bolts, and a rotating frame is rotatably connected to the outside of the mounting seat; a sealing component is used to improve the sealing performance between the touch screen body and the rotating frame, and the sealing component is connected to the mounting seat.

[0008] Optionally, the sealing assembly includes four clamping parts which are equidistantly fixedly connected to the outside of the mounting seat, and four clamping grooves which are matched with the four clamping parts are formed on the inner wall of the rotating frame.

[0009] Optionally, the clamping part includes two No. 1 spring pieces fixedly connected to the outer wall of the mounting seat, a No. 2 spring piece is provided at the outward ends of the two No. 1 spring pieces, a No. 3 spring piece is fixedly connected above the junction of the two No. 1 spring pieces and the No. 2 spring pieces, and a weakening groove is provided on the inner wall of the No. 2 spring piece.

[0010] Optionally, a limiting groove is provided at the top of the inner cavity of the rotating frame, and one side of the limiting groove is an inclined surface.

[0011] Optionally, a sealing ring is provided between the touch screen body and the rotating frame, and one side of the sealing ring contacts the inclined surface of the limiting groove.

[0012] Optionally, the bottom of the sealing ring is a semicircular protrusion, and the semicircular protrusion of the sealing ring is in conflict with the sealing assembly.

[0013] Optionally, the clamping member is made of elastic material and is integrally formed.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, by setting the clamping parts and the sealing gasket, when the touch screen body does not need to be rotated by the rotating frame, it can effectively prevent external substances such as dust and moisture from entering the gap between the touch screen body and the rotating frame, thereby improving the reliability and durability of the device. When the rotating frame is needed to rotate the touch screen body, the clamping parts (including the first spring clip, the second spring clip and the third spring clip) will be deformed, allowing the sealing gasket (or called the sealing gasket) to move downward without hindering the rotation of the rotating frame, thereby ensuring the smoothness and convenience of the operation.

[0016] By providing an inclined limiting groove and a sealing gasket adapted thereto, the inclined limiting groove design enables the sealing gasket to fit along the inclined surface more easily when under pressure, forming a tighter sealing structure, and the design of the inclined surface enables the sealing gasket to produce a certain self-locking effect when under pressure, further reducing the risk of leakage, and the tightly fitting sealing structure can reduce the wear and aging of the sealing gasket, thereby extending its service life. At the same time, since the risk of leakage is reduced, the possibility of damage to the touch screen body and the rotating frame due to the intrusion of external substances can also be reduced.

[0017] The design of the entire sealing assembly is relatively simple, and the clamping parts are made of elastic material and are integrally formed, which reduces the production cost and makes installation and maintenance more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a touch screen with a touch knob, including a mounting base 2, a touch screen body 3 is installed inside the mounting base 2 by bolts, and a rotating frame 1 is rotatably connected to the outside of the mounting base 2. During the installation process, the touch screen body 3 is installed inside the mounting base 2 by bolts, and a roller structure is installed outside the mounting base 2 to enable the rotating frame 1 to slide smoothly.

[0032] like Figures 1 to 4As shown, the sealing component is used to improve the sealing performance between the touch screen body 3 and the rotating frame 1. The sealing component is connected to the mounting seat 2. The sealing component includes four clamping members 4 equidistantly fixedly connected to the outside of the mounting seat 2. Four card slots 7 adapted to the four clamping members 4 are provided on the inner wall of the rotating frame 1. The clamping member 4 includes two No. 1 spring pieces 401 fixedly connected to the outer wall of the mounting seat 2. The outward ends of the two No. 1 spring pieces 401 are provided with No. 2 spring pieces 402. A No. 3 spring piece 405 is fixedly connected above the junction of the two No. 1 spring pieces 401 and the No. 2 spring pieces 402. A weakening groove 403 is provided on the inner wall of the No. 2 spring piece 402. A limiting groove 5 is provided at the top of the inner cavity of the rotating frame 1, and one side of the limiting groove 5 is an inclined surface. A sealing ring 6 is provided between the touch screen body 3 and the rotating frame 1, and one side of the sealing ring 6 contacts with the inclined surface of the limiting groove 5, and the bottom of the sealing ring 6 is semicircular. The protrusion, the semicircular protrusion of the sealing ring 6 is bonded to the sealing component, the clip 4 is made of elastic material, and the clip 4 is integrally formed. When the rotating frame 1 is in a stationary state, the No. 2 spring pieces 402 of the four clips 4 cooperate with the card groove 7 on the inner wall of the rotating frame 1 to form a stable fixed structure. At the same time, the bottom of the sealing ring 6 contacts the clip 4, and its side is tightly fitted with the inclined surface of the limiting groove 5 at the top of the inner cavity of the rotating frame 1 to form a sealing barrier, which effectively prevents external substances such as dust and moisture from entering the gap between the touch screen body 3 and the rotating frame 1. When the touch screen body 3 needs to be rotated, the user applies a certain force to rotate the rotating frame 1. At this time, the No. 1 spring piece 401 and the No. 2 spring piece 402 of the clip 4 are squeezed by the card groove 7 and deformed at the weakened groove 403, and the No. 3 spring piece 405 also undergoes a certain deformation, so that the clip 4 can slide smoothly along the card groove 7. During this process, the sealing ring 6 is squeezed and its bottom will be temporarily separated from the clamp 4, while the side will slide along the inclined surface of the limiting groove 5. Due to the inclined surface design of the limiting groove 5, the sealing ring 6 can maintain a close fit with the inclined surface during the sliding process, thereby ensuring that it still has a certain sealing effect during the rotation process. In the static state, the second spring piece 402 of the clamp 4 is tightly matched with the clamping groove 7 to form a stable fixed structure. The bottom of the sealing ring 6 contacts the clamp 4, and the side is tightly fitted with the inclined surface of the limiting groove 5 to form a sealing barrier.

[0033] When the rotating frame 1 starts to rotate, the first spring piece 401 and the second spring piece 402 of the clamping part 4 are squeezed by the clamping groove 7 and deformed. At this time, the third spring piece 405 also starts to deform to adapt to the sliding of the clamping part 4 in the clamping groove 7. During the rotation process, the clamping part 4 continues to slide along the clamping groove 7. At the same time, the sealing ring 6 is squeezed, and its bottom is temporarily separated from the clamping part 4. The side of the sealing ring 6 slides along the inclined surface of the limiting groove 5. Due to the design of the inclined surface, the sealing ring 6 can maintain a close fit with the inclined surface. When the rotating frame 1 stops rotating, the clamping part 4 returns to its original state under the action of elastic force and fits tightly with the clamping groove 7 again. The sealing ring 6 also returns to its initial state, with the bottom in contact with the clamping part 4 and the side in close fit with the inclined surface of the limiting groove 5 to form a sealing barrier.

[0034] It should be noted that the above solution has the installation method of the installation base 2 and the touch screen body 3 and the roller structure are all existing technologies, so there is no need to elaborate on them.

[0035] In the workflow provided by the utility model, the clamping member 4 of the sealing assembly is closely matched with the clamping groove 7 on the inner wall of the rotating frame 1 to ensure the sealing performance in static state. The sealing ring 6 is closely fitted with the inclined surface of the limiting groove 5 to form an initial sealing state. When the touch screen body 3 needs to be rotated, the user applies force to make the rotating frame 1 start to rotate. In this process, the first spring piece 401 and the second spring piece 402 of the clamping member 4 are deformed, allowing the rotating frame 1 to rotate relative to the mounting seat 2. The third spring piece 405 is also deformed to adapt to this movement. As the rotating frame 1 continues to rotate, the sealing ring 6 is squeezed and slides along the inclined surface of the limiting groove 5. Due to the design of the inclined surface, the sealing ring 6 can maintain a close fit with the inclined surface, thereby maintaining a certain sealing effect during the rotation process. When the rotating frame 1 stops rotating after reaching the desired position, the clamping member 4 returns to its original state under the action of the elastic force and is closely matched with the clamping groove 7 again. At the same time, the sealing ring 6 also returns to its original state and fits tightly with the inclined surface of the limiting groove 5 again, ensuring the sealing performance between the touch screen body 3 and the rotating frame 1. Through the deformation of the clamping part 4 and the design of the sealing ring 6, the sealing requirement of the touch screen body 3 during the rotation process is achieved, and the smoothness of the rotation is guaranteed.
