Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaners for coating machines, specifically a vacuum cleaner for coating machines with replaceable vacuum heads. Background Technology

[0002] A coating machine vacuum cleaner is a machine used to clean the inside of a coating machine. By assembling different replacement heads, different cleaning methods can be performed. The stability of the assembly between the replacement head and the suction pipe can be improved by setting a corresponding assembly structure. However, during use, it is inconvenient to control the assembly stability, which can easily cause the replacement head to fall off.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN202220488921.7, filed on 2022-03-08) provides a replaceable industrial vacuum cleaner. When the connecting tube is connected to the first mounting component via a connector and a fixed tube, the handheld vacuum stick can be operated during vacuuming, allowing the replacement head to vacuum the processing area or locations inaccessible to the vacuum cleaner. When the connecting tube is connected to the second mounting component via a connector and a fixed tube, the floor vacuum box can be used to vacuum the floor, and pushing the vacuum cleaner can continuously suck up dust from the floor. In actual use, the handheld vacuum stick or the floor vacuum box can be replaced according to cleaning needs. Although the prior art allows for assembly, the replacement head is prone to falling off during operation due to prolonged movement, and it is inconvenient to control the stability of the replacement head assembly, affecting the vacuuming effect and easily damaging other machines inside the coating machine.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing coating machine vacuum cleaners with replaceable suction heads. Utility Model Content

[0005] The purpose of this utility model is to provide a coating machine vacuum cleaner with a replaceable vacuum head, so as to solve the problems mentioned in the background art, that the replaceable head is prone to falling off during long-term movement, and that it is inconvenient to control the stability of the replaceable head assembly, which affects the vacuuming effect and is prone to damaging other machines inside the coating machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating machine vacuum cleaner with a replaceable vacuum head, comprising a vacuum tube and a sealing ring assembled on the inner surface of the vacuum tube; including: a nested tube, nested and connected to the inner surface of the vacuum tube, with a nested ring installed at the outer end of the nested tube, and a positioning block one installed on the outer surface of the nested ring, which engages with the inner surface of the sealing ring; a positioning block two installed on the outer surface of the nested tube, which limits and engages with the inner surface of the vacuum tube; a fixing plate, installed on the left side of the outer surface of the vacuum tube, with an anti-detachment ring slidably connected to the outer surface of the vacuum tube, and a spring two elastically connected between the anti-detachment ring and the fixing plate; and a compression ring installed on the inner surface of the anti-detachment ring, which is nested on the lower left side of the compression plate.

[0007] Preferably, the nested tube forms a nested engagement structure with the vacuum tube through a nested ring and a positioning block one, and the nested tube forms a nested structure with the vacuum tube through a positioning block two, and the positioning blocks one and two are set at equal angles about the central axis of the nested tube.

[0008] Preferably, a replacement head is installed on the outer surface of the nested tube, and a limiting ring is installed on the outer surface of the replacement head. The limiting ring is nested on the outer end of the vacuum tube. A squeezing plate is rotatably connected to the outer surface of the vacuum tube. A locking block is installed on the outer end of the squeezing plate and is locked in the limiting ring. A spring is installed on the right side between the squeezing plate and the vacuum tube.

[0009] Preferably, the nested tube, the replacement head, and the limiting ring form an integrated structure, and the limiting ring and the vacuum tube form an embedded structure. The vacuum tube and the extrusion plate form an elastic rotation structure through a spring, and the extrusion plate and the limiting ring form a limiting engagement structure through a locking block.

[0010] Preferably, the suction pipe and the fixing plate form an integrated structure, and the fixing plate forms an elastic telescopic structure with the second spring and the anti-detachment ring, and the anti-detachment ring and the suction pipe form a nested sliding structure. At the same time, the anti-detachment ring forms a compression limiting structure with the compression ring and the compression plate.

[0011] Preferably, the inner surface of the anti-detachment ring is rotatably slidably connected to a slider, and the outer surface of the slider is equipped with a rotating ring. A spring is elastically connected between the anti-detachment ring and the slider. At the same time, an unlocking block is installed on the outer surface of the rotating ring and connected to the outer surface of the extrusion plate.

[0012] Preferably, the anti-detachment ring forms an elastic limiting sliding structure with the rotating ring through the spring, the slider, and the rotating ring forms a compression unlocking structure with the compression plate through the unlocking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This coating machine vacuum cleaner with replaceable vacuum heads is equipped with a nested tube for nested assembly of the vacuum hose, and a replacement head and limiting ring installed on the nested tube. It can be stably nested at the vacuum end of the vacuum hose, and the stability of the replacement head assembly can be controlled. In conjunction with the elastically assembled locking block on the outside of the vacuum hose, the stability of the replacement head assembly is controlled. The use of an anti-detachment ring improves the anti-detachment effect, and the rotating ring nested with the anti-detachment ring facilitates quick disengagement during later unlocking.

[0015] 2. The coating machine vacuum cleaner with replaceable vacuum head is equipped with a nested positioning block 1 for easy internal installation, which can control the positioning and nesting between the sealing ring and the nested tube. The positioning block 2 assembled through the nested tube can control the stability of the independent connection between the end of the replacement head and the vacuum tube. The cooperation of the limiting ring and the locking block improves the locking stability. Furthermore, the compression plate installed on the locking block is set at an angle with elasticity to prevent the locking structure from disengaging.

[0016] 3. This coating machine vacuum cleaner with a replaceable vacuum head is equipped with an anti-detachment ring for sliding connection of the vacuum tube. The elastic setting between the two, together with the spring, allows the control squeezing ring to lift the rear end of the squeezing plate after the locking block is engaged. The locking block installed at the front end will stably engage in the limiting ring, improving the engagement stability. In addition, the rotating ring on the anti-detachment ring, together with the installed unlocking block, controls multiple sets of squeezing plates to disengage synchronously, improving the convenience of unlocking and replacement.

[0025] 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.

[0026] Please see Figures 1-7 The present invention provides the following technical solution: a coating machine vacuum cleaner with a replaceable vacuum head, wherein a vacuum tube 1 and a sealing ring 2 assembled on the inner surface of the vacuum tube 1 are provided.

[0027] Example 1: As Figures 1-4 The technical solution shown is provided by this utility model as follows: A coating machine vacuum cleaner with a replaceable vacuum head, comprising: a nested tube 3, nested and connected to the inner surface of a vacuum tube 1, and a nested ring 4 installed at the outer end of the nested tube 3; a positioning block 5 is installed on the outer surface of the nested ring 4, and the positioning block 5 is engaged with the inner surface of a sealing ring 2; simultaneously, a positioning block 6 is installed on the outer surface of the nested tube 3, and the positioning block 6 is limited and engaged with the inner surface of the vacuum tube 1; as shown... Figure 3 As shown, the nested tube 3 forms a nested engagement structure with the vacuum tube 1 through the nested ring 4 and the positioning block 1 5, and the nested tube 3 also forms a nested structure with the vacuum tube 1 through the positioning block 2 6. Furthermore, the positioning blocks 1 5 and 2 6 are set at equal angles about the central axis of the nested tube 3. Figure 3 and Figure 4 As shown, a replacement head 7 is installed on the outer surface of the nested tube 3, and a limiting ring 8 is installed on the outer surface of the replacement head 7. The limiting ring 8 is nested at the outer end of the suction tube 1, and a squeezing plate 9 is rotatably connected to the outer surface of the suction tube 1. At the same time, a locking block 10 is installed at the outer end of the squeezing plate 9, and the locking block 10 is limited and engaged in the limiting ring 8. A spring 11 is installed on the right side between the squeezing plate 9 and the suction tube 1. Figure 3 and Figure 4As shown, the nested tube 3, the replacement head 7, and the limiting ring 8 form an integrated structure, and the limiting ring 8 and the vacuum tube 1 form an embedded structure. The vacuum tube 1 and the extrusion plate 9 form an elastic rotation structure through the spring 11, and the extrusion plate 9 and the limiting ring 8 form a limiting engagement structure through the locking block 10.

[0028] In use, the anti-detachment ring 14 on the vacuum tube 1 is squeezed to the left, causing the rotating ring 17 to rotate synchronously. The unlocking block 19 controls the locking block 10 installed on the squeezing plate 9 to lift, thus controlling the nested tube 3 installed on the replacement head 7 to be stably nested in the vacuum tube 1. The nested ring 4 installed on the left end of the nested tube 3, and the equidistant positioning blocks 1 and 5, are also stably nested on the sealing ring 2, thereby controlling the stability of the nested tube 3 assembly. When the positioning block 1 and 5 of the nested tube 3 are positioned and nested, they cooperate with the positioning block 2 and 6 installed on the outside of the nested tube 3 to stabilize it. The replacement head 7 is nested inside the right end of the vacuum tube 1, improving the stability of the connection between the vacuum tube 1 and the nested tube 3. This, in turn, improves the stability of the assembly of the replacement head 7 installed on the nested tube 3. In conjunction with the limiting ring 8 installed on the replacement head 7, it is effectively nested outside the right end of the vacuum tube 1, improving the stability of the nested assembly and preventing it from falling off. Panasonic also squeezes the squeezing plate 9 of the rotating assembly of the vacuum tube 1. The right side of the squeezing plate 9 will elastically contract and reset with the spring 11, controlling the locking block 10 installed on the squeezing plate 9 to stably engage in the limiting ring 8, improving the engagement stability and increasing the assembly stability.

[0029] Example 2: Figure 5 The technical solution shown, based on Embodiment 1, further discloses the stability of the assembly and locking positioning, and improves the convenience of subsequent unlocking, solving the problem that the replacement head 7 is prone to falling off during long-term movement. Its specific content is as follows: A fixing plate 12 is installed on the left side of the outer surface of the vacuum tube 1, and an anti-detachment ring 14 is slidably connected to the outer surface of the vacuum tube 1. A spring 13 is elastically connected between the anti-detachment ring 14 and the fixing plate 12. Simultaneously, a compression ring 15 is installed on the inner surface of the anti-detachment ring 14, and the compression ring 15 is nested on the lower left side of the compression plate 9; Figure 5 As shown, the vacuum tube 1 and the fixing plate 12 form an integrated structure, and the fixing plate 12 forms an elastic telescopic structure with the spring 13 and the anti-detachment ring 14. The anti-detachment ring 14 and the vacuum tube 1 form a nested sliding structure, and the anti-detachment ring 14 forms a compression limiting structure with the compression ring 15 and the compression plate 9.

[0030] When replacement is needed, hold the vacuum hose 1 steadily with one hand, and use another finger to control the anti-detachment ring 14 to slide to the left side of the vacuum hose 1. This controls the spring 13 between the anti-detachment ring 14 and the fixing plate 12 to retract, and moves the compression ring 15 installed on the anti-detachment ring 14 away from the underside of the compression plate 9. This makes it easier to unlock the compression plate 9 later. After replacement, loosen the anti-detachment ring 14. At this time, the anti-detachment ring 14 will unfold due to the elasticity of the spring 13. Control the anti-detachment ring 14 to slide to the right, thereby moving the compression ring 15 installed on the anti-detachment ring 14 to the underside of the compression plate 9. This fills the gap between the left side of the compression plate 9 and the vacuum hose 1, preventing the compression plate 9 from disengaging and improving the stability of the assembly after replacement.

[0031] Example 3: Figure 6 and Figure 7 The technical solution shown, based on Embodiment 2, further discloses that after unlocking, multiple locking mechanisms can be simultaneously adjusted by one hand to control the ease of locking assembly. This solves the problems of inconvenient control over the stability of replacement head assembly, affecting dust collection performance, and easily damaging other machines inside the coating machine. The specific details are as follows: A slider 16 is rotatably and slidably connected to the inner surface of the anti-detachment ring 14, and a rotating ring 17 is installed on the outer surface of the slider 16. A spring 18 is elastically connected between the anti-detachment ring 14 and the slider 16. Simultaneously, an unlocking block 19 is installed on the outer surface of the rotating ring 17 and connected to the outer surface of the extrusion plate 9; Figure 6 and Figure 7 As shown, the anti-detachment ring 14 forms an elastic limiting sliding structure with the rotating ring 17 through the spring 18 and the slider 16, and the rotating ring 17 forms a compression unlocking structure with the compression plate 9 through the unlocking block 19.

[0032] During unlocking, the leftward sliding of the anti-detachment ring 14 will synchronously drive the rotating ring 17 to move synchronously. When multiple sets of extrusion plates 9 need to be unlocked simultaneously, the slider 16 installed on the rotating ring 17 is controlled to nest and rotate on the anti-detachment ring 14, and the spring 18 between the slider 16 and the anti-detachment ring 14 is compressed and contracted. This controls the unlocking block 19 installed on the rotating ring 17 to compress the left side of the extrusion plate 9, controlling multiple sets of extrusion plates 9 to be simultaneously positioned and rotated outside the vacuum tube 1. The locking block 10 installed on the left side of the extrusion plate 9 is disengaged from the limiting ring 8 for replacement of the new replacement head 7. After the replacement head 7 is assembled, the rotating ring 17 is loosened to cause the extrusion plate 9 to elastically contract and lock. The anti-detachment ring 14 is loosened to fill the gap and limit the extrusion plate 9 in the locked state, preventing it from falling off, improving the stability of the locking, and preventing the locking from disengaging.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
