DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] See also Figures 1 to 13 The present invention provides a technical solution: a gas cylinder quick cleaning device, comprising a cleaning rod 2, wherein the cleaning rod 2 is inserted into the gas cylinder 1, and a side cleaning component for cleaning the inner wall of the gas cylinder 1 is horizontally slidably arranged on the inner side of the cleaning rod 2, and an adjusting component for adjusting the position of the cleaning component is rotatably arranged in the cleaning rod 2, and the adjusting component is in contact and cooperate with the side cleaning component. When the adjusting component rotates, the adjusting component drives the side cleaning component to move horizontally toward the inner wall of the gas cylinder 1 to meet the cleaning needs of gas cylinders 1 with different inner wall sizes, and an arc cleaning component for cleaning the top of the inner wall of the gas cylinder 1 is connected above the side cleaning component, and a support component is rotatably connected to the side of the side cleaning component close to the back of the arc cleaning component. When the side cleaning component is expanded outward, the support component supports the back side of the arc cleaning component, so that the arc cleaning component is in more complete contact with the top of the inner wall of the gas cylinder 1.

[0031] In actual use, in the initial state, the side cleaning component and the curved cleaning component are located inside the cleaning rod 2; when the inner wall of the gas cylinder 1 needs to be cleaned, the adjusting component is rotated, and the adjusting component drives the side cleaning component to expand outward from the cleaning rod 2, and the side cleaning component gradually contacts and fits with the inner wall of the gas cylinder 1, and then the cleaning rod 2 is rotated to drive the side cleaning component to clean the inner wall of the gas cylinder 1. By controlling the rotation of the adjusting component, the distance that the side cleaning component moves outward from the cleaning rod 2 is changed, so that the side cleaning component can clean gas cylinders 1 with different inner wall sizes; since the top of the inner wall of the gas cylinder 1 is a curved surface, this part is extremely difficult to clean, resulting in incomplete cleaning of the inner wall of the gas cylinder 1, When the side cleaning assembly moves toward the outside of the cleaning rod 2, it drives the arc surface cleaning assembly to move out of the cleaning rod 2, and the arc surface cleaning assembly gradually contacts and fits with the top of the inner wall of the gas cylinder 1, and under the rotation of the cleaning rod 2, the top of the inner wall of the gas cylinder 1 is cleaned, so that the cleaning strip 7 can effectively clean the arc surface of the upper end of the inner wall of the gas cylinder 1, which is extremely difficult to clean. At the same time, the side cleaning assembly drives the supporting assembly to rotate upward, so that the supporting assembly supports the arc surface cleaning assembly upward from the back side, and the arc surface cleaning assembly contacts the upper end of the inner wall of the gas cylinder 1 more fully, avoiding insufficient contact between the middle position of the arc surface at the top end of the inner wall of the gas cylinder 1 and the arc surface cleaning assembly, resulting in incomplete cleaning of the inner wall of the gas cylinder 1, thereby improving the cleaning efficiency.

[0032] As an embodiment of the present invention, Figure 1-Figure 8 , Fig.13 As shown, placement grooves 201 for placing side cleaning components are vertically opened on both sides of the cleaning rod 2, and fixed blocks 4 are horizontally fixed at the upper and lower ends of the placement grooves 201. The side cleaning component includes a cleaning plate 6, and soft brushes are distributed and arranged on the side of the cleaning plate 6 close to the inner wall. The upper and lower ends of the cleaning plate 6 are horizontally slidably matched with the placement grooves 201, and the cleaning plate 6 is elastically connected to the bottom end of the placement grooves 201. A sliding block 5 is horizontally fixed on the side of the cleaning plate 6 close to the fixed block 4, and a second sliding groove 502 is horizontally opened on one end of the sliding block 5 close to the fixed block 4. The fixed block 4 is slidably matched with the second sliding groove 502, and the sliding block 5 is slidably sleeved on the outside of the fixed block 4. A push plate 501 is vertically fixed to the bottom end of the sliding block 5 close to the placement groove 201, and the push plate 501 contacts and cooperates with one end of the adjusting component.

[0033] As an embodiment of the present invention, Figure 1-Figure 2 , Figure 4-Figure 6 , Figure 8 , Fig.13 As shown, the adjustment assembly includes a first drive shaft 3, which is vertically rotatably connected to the center of the cleaning rod 2. A cam 301 is horizontally fixed on one side of the first drive shaft 3 close to the push plate 501, and the cam 301 is in contact with the push plate 501.

[0034] During actual use, in the initial state, the cleaning plate 6 is located in the placement groove 201, and the short axis part of the cam 301 is in contact with the push plate 501; when the first drive shaft 3 rotates, the cam 301 is driven to rotate, and the cam 301 pushes the push plate 501 toward the outside of the placement groove 201, driving the sliding block 5 to move toward the outside of the cleaning rod 2. At this time, the sliding block 5 slides on the outside of the fixed block 4, so that the cleaning plate 6 moves toward the inner wall of the gas cylinder 1 and contacts and fits the inner wall; the rotation angle of the cam 301 is controlled by the first drive shaft 3. At this time, the distance between the cleaning plate 6 and the inner wall can be adjusted according to the diameter of the inner wall of the gas cylinder 1, so that the brush on the cleaning plate 6 is completely in contact with the inner wall, thereby improving the cleaning efficiency.

[0035] As an embodiment of the present invention, Figure 1-Figure 13 As shown, the side wall of the cleaning rod 2 located above the placement groove 201 is vertically opened with a first sliding groove 202, and the side wall of the first sliding groove 202 is vertically opened with a first guide groove 203, and the arc surface cleaning component includes a cleaning strip 7, and soft brushes are distributed and arranged on the side of the cleaning strip 7 close to the inner wall, and guide blocks 701 are vertically fixed on both sides of the cleaning strip 7, and the guide blocks 701 are slidably matched with the first guide groove 203, and the lower end of the cleaning strip 7 is fixedly connected to the cleaning plate 6, and the cleaning strip 7 is made of soft material, and the upper end of the cleaning strip 7 is elastically connected to the top of the first sliding groove 202.

[0036] As an embodiment of the present invention, Figure 4-Figure 6 , Figure 8-Figure 12 As shown, the sliding block 5 at the upper end of the cleaning plate 6 is rotatably connected to the supporting assembly, a second guide groove 402 is horizontally penetrated on one side of the fixed block 4 at the upper end of the placement groove 201 near the sliding block 5, and a first rotation groove 401 is vertically penetrated in the middle of the second guide groove 402, a rack 403 is vertically fixed on the upper side of the fixed block 4, a round rod 503 is horizontally rotatably connected in the second sliding groove 502, first gears 504 are fixed at both ends of the round rod 503 near the side wall of the second sliding groove 502, the first gear 504 is meshed with the rack 403 for transmission, the round rod 503 is slidably matched with the second guide groove 402, a second rotation groove 507 is vertically penetrated in the second sliding groove 502, and the second rotation groove 507 corresponds to the first rotation groove 401, the supporting assembly is rotatably connected to the middle of the round rod 503, and the supporting assembly rotates around the round rod 503 in the first rotation groove 401 and the second rotation groove 507.

[0037] In actual use, in the initial state, the cleaning strip 7 is located in the first sliding groove 202, and the supporting assembly is in a horizontal state; when the cleaning plate 6 approaches the inner wall, the upper end of the cleaning plate 6 drives the cleaning strip 7 to slide outward from the first sliding groove 202 until the brush on the outer side of the cleaning plate 6 is in contact with the inner wall. At this time, the brush on the outer side of the cleaning strip 7 is in contact with the arc surface of the upper end of the inner wall of the gas cylinder 1, and the cleaning rod 2 is rotated so that the cleaning strip 7 can effectively clean the arc surface of the upper end of the inner wall of the gas cylinder 1, which is a very difficult part to clean; 7 is straight under the stretching of the cleaning plate 6. When the curvature of the top end of the inner wall of the gas cylinder 1 changes, the middle position of the curved surface is not in sufficient contact with the cleaning strip 7, resulting in incomplete cleaning of the curved surface. Therefore, when the cleaning plate 6 approaches the inner wall, the rack 403 drives the first gear 504 to rotate, drives the round rod 503 to rotate, and drives the supporting assembly to rotate upward, so that the supporting assembly supports upward from the back side of the cleaning strip 7, avoiding insufficient contact between the middle position of the curved surface of the top end of the inner wall of the gas cylinder 1 and the curved surface cleaning assembly, resulting in incomplete cleaning of the inner wall of the gas cylinder 1, thereby improving the cleaning efficiency.

[0038] As an embodiment of the present invention, Figure 4-Figure 6 , Figure 8-Figure 12 As shown, the support assembly includes a first support plate 505, one end of the first support plate 505 close to the round rod 503 is rotatably connected to the round rod 503, and the end of the first support plate 505 away from the round rod 503 is rotatably connected to a second support plate 506, the second support plate 506 is arc-shaped, and the second support plate 506 is elastically connected to the first support plate 505.

[0039] In actual use, in the initial state, the first support plate 505 is parallel to the cleaning rod 2; when the cleaning plate 6 moves toward the inner wall of the gas cylinder 1, the rack 403 drives the first gear 504 to rotate, drives the round rod 503 to rotate, drives the first support plate 505 to rotate upward, drives the second support plate 506 to contact and squeeze the cleaning strip 7 upward, and the top arc surface of the inner wall of the gas cylinder 1 is completely in contact with the brush on the outside of the cleaning strip 7, thereby improving the cleaning efficiency; when the top arc surface of the inner wall changes, in order to adapt to the arc surface of the inner wall of the gas cylinder 1 of different sizes, when the second support plate 506 squeezes the cleaning strip 7 to fit the arc surface, the arc surface and the cleaning strip 7 reversely squeeze the second support plate 506, so that the second support plate 506 rotates toward the first support plate 505 and squeezes the spring, which not only makes the second support plate 506 applicable to the inner wall arc surfaces of different sizes, but also protects the second support plate 506 from being reversely squeezed and broken by the arc surface and the cleaning strip 7 when the arc surface changes.

[0040] As an embodiment of the present invention, Figure 1-Figure 2 , Figure 4 ,as well as Figure 7As shown, a control box 8 is provided at the upper end of the cleaning rod 2, and the lower end of the control box 8 is rotatably connected to the cleaning rod 2. A first motor 801 and a second motor 802 are fixed to the upper end of the control box 8, and the lower end of the first motor 801 is rotatably connected to the upper end of the first driving shaft 3. The upper end of the cleaning rod 2 is located in the control box 8 and a second gear 803 is fixed thereto, and the lower end of the second motor 802 is rotatably connected to the second driving shaft 805, and a third gear 804 is fixed to the outer side of the second driving shaft 805, and the second gear 803 and the third gear 804 are meshed with each other.

[0041] Working principle: After the cleaning rod 2 is inserted into the gas cylinder 1, the cleaning plate 6 is operated to move toward the inner wall of the gas cylinder 1 and contact and fit the inner wall, and the rotation angle of the cam 301 is controlled by controlling the first motor 801, and the distance between the cleaning plate 6 and the inner wall is adjusted according to the diameter of the inner wall of the gas cylinder 1, so that the brush on the cleaning plate 6 is completely in contact with the inner wall, thereby improving the cleaning efficiency; when the cleaning plate 6 moves toward the inner wall of the gas cylinder 1, the cleaning plate 6 drives the brush on the outer side of the cleaning strip 7 to contact and fit the arc surface of the upper end of the inner wall of the gas cylinder 1, and under the rotation of the cleaning rod 2, the cleaning strip 7 effectively cleans the arc surface of the upper end of the inner wall of the gas cylinder 1, which is extremely difficult to clean; when the cleaning plate 6 moves toward the inner wall While approaching, the first support plate 505 drives the second support plate 506 to contact and squeeze the cleaning strip 7 upward, so that the curved surface at the top end of the inner wall of the gas cylinder 1 is completely in contact with the brush on the outside of the cleaning strip 7, thereby improving the cleaning efficiency and avoiding incomplete cleaning of the curved surface due to insufficient contact between the middle position of the curved surface and the cleaning strip 7 when the curvature of the top end of the inner wall of the gas cylinder 1 changes; in order to adapt to the change of the curved surface at the top end of the inner wall, the first support plate 505 and the second support plate 506 are rotatably connected and a spring is added in the middle, which not only makes the second support plate 506 applicable to the curved surfaces of the inner wall of different sizes, but also protects the second support plate 506 from being broken by the reverse extrusion of the curved surface and the cleaning strip 7 when the curved surface changes.
