Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, specifically to an automatic vacuuming device that facilitates the replacement of vacuum bags. Background Technology

[0002] In the production process of bearings, a series of steps such as forging, heat treatment, and grinding are required. The grinding operation of bearings usually uses a grinding machine to grind the bearing surface. During the grinding process, a lot of metal chips and dust are generated. In order to keep the production environment clean, these metal chips and dust need to be treated by a dust collection device.

[0003] In the prior art, patent CN216320618U discloses a dust removal device that facilitates the replacement of dust collection bags. The device includes a housing that moves via rollers, with an air pump installed at the lower right end of the housing and a motor bolted to the upper rear end. It also includes a storage frame embedded in the bottom of the housing, with an air extraction pipe engaged at the right end of the frame, and the right end of the air extraction pipe bolted to the left end of the air pump; and a dust collection bag body placed inside the storage frame, with a limiting mechanism on the upper side of the dust collection bag body, the limiting mechanism including a limiting element, a threaded rod, a mounting plate, and a guide rod.

[0004] This type of dust collection device, which facilitates the replacement of dust bags, has the following disadvantages: the screw rotates to drive the limiting component to move, thereby fixing the dust bag in conjunction with the mounting plate. When replacing the dust bag, the screw needs to be rotated repeatedly, which is cumbersome. At the same time, the screw is prone to blockage after prolonged use inside the box, resulting in poor practicality. Therefore, we propose an automatic dust collection device that facilitates the replacement of dust bags. Utility Model Content

[0005] The technical problem this utility model aims to solve is to overcome the existing defects and provide an automatic vacuuming device that facilitates the replacement of vacuum bags. Through a fixing mechanism, the movable seat presses against the connecting rod two, thereby driving the sliding rod two to move, which in turn moves the connecting rod one, and in turn drives the sliding rod one to move. This allows the semi-circular clamping rod and the semi-circular rubber pad to work with the support block to fix the vacuum bag. The vacuum bag can be disassembled and assembled by moving the movable seat a short distance. The operation is simple, the response speed is fast, and the practicality is good. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic vacuum cleaner that facilitates the replacement of vacuum bags, comprising a base, a vacuum cylinder fixedly connected to the left side of the upper surface of the base, a suction pipe fixedly connected to the left side of the outer surface of the vacuum cylinder, a vacuum head fixedly connected to the left end of the suction pipe, a support block fixedly connected inside the vacuum cylinder, a through hole opened inside the support block, a vacuum bag fitted on the lower side of the outer surface of the support block, and a fixing mechanism;

[0007] The fixing mechanism includes a fixed base, a sliding rod, a semi-circular clamping rod, and a semi-circular rubber pad. The fixed base is fixedly connected to the front and rear sides of the inner surface of the vacuum cleaner. The sliding rod is slidably connected inside the fixed base. A semi-circular clamping rod is fixedly connected to the end of the sliding rod near the middle of the vacuum cleaner. A semi-circular rubber pad is fixedly connected to the inner arc surface of the semi-circular clamping rod. Through the fixing mechanism, the movable base presses the connecting rod, thereby moving the sliding rod, which in turn moves the connecting rod, which in turn moves the sliding rod. The semi-circular clamping rod and the semi-circular rubber pad, together with the support block, fix the vacuum bag. The vacuum bag can be disassembled and assembled by only moving the movable base a short distance. The operation is simple, the response speed is fast, and the practicality is good.

[0008] Furthermore, the feature is that a control switch is fixedly connected to the front surface of the vacuum cleaner, and the input end of the control switch is electrically connected to an external power source to control the operation of the electrical appliances.

[0009] Furthermore, the fixing mechanism also includes a second slide rod, a first connecting rod, a first spring, and a movable seat. The second slide rod is slidably connected to the front and rear sides of the inner surface of the vacuum cleaner. The side of the second slide rod near the middle of the vacuum cleaner is rotatably connected to the lower surface of the first slide rod on the same side. The upper surface of the second slide rod is fixedly connected to the lower surface of the fixed seat on the same side. The two second slide rods are fixedly connected to each other. The lower surface of the vacuum cleaner is slidably connected to the movable seat, which is installed in conjunction with the second connecting rod to transmit driving force.

[0010] Furthermore, the fixing mechanism also includes a slider, three springs, and a limiting groove. The slider is slidably connected to the inside of the movable seat. Symmetrically distributed three springs are fixedly connected between the stepped surface of the slider and the inner wall of the movable seat. A limiting block is fixedly connected to the lower surface of the slider. A limiting groove is opened on the lower surface of the inside of the dust collection tube. The limiting block is engaged in the limiting groove to lock the movable seat.

[0011] Furthermore, a fan is fixedly connected to the right side of the upper surface of the base. The air inlet of the fan is connected to the dust collection cylinder through an exhaust pipe. A filter screen is fixedly connected to the left end of the exhaust pipe. The input end of the fan is electrically connected to the output end of the control switch, so that negative pressure is generated inside the dust collection cylinder to suck in debris and dust.

[0012] Furthermore, a sealed access door is hinged to the left side of the outer surface of the base. A sealing rubber gasket is fixedly connected to the connection between the outer surface of the sealed access door and the dust collection cylinder. A fixing block is fixedly connected to the rear side of the sealed access door. A slot is provided on the upper side of the inside of the fixing block. An insert block is slidably connected to the inside of the dust collection cylinder. The insert block is inserted into the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic vacuum cleaner device that facilitates the replacement of vacuum bags has the following advantages:

[0015] The fixed mechanism causes the movable seat to press the connecting rod 2, thereby moving the sliding rod 2, which in turn moves the connecting rod 1, which in turn moves the sliding rod 1. This allows the semi-circular clamp and the semi-circular rubber pad to work with the support block to fix the dust bag. The dust bag can be assembled and disassembled by simply moving the movable seat a short distance. The operation is simple, the response is fast, and it is very practical.

[0024] 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.

[0025] Please see Figure 1-7This embodiment provides a technical solution: an automatic vacuum cleaner with a convenient dust bag replacement, including a base 1, a vacuum cylinder 2 fixedly connected to the left side of the upper surface of the base 1, a suction pipe 3 fixedly connected to the left side of the outer surface of the vacuum cylinder 2, a suction head 4 fixedly connected to the left end of the suction pipe 3, a support block 17 fixedly connected inside the vacuum cylinder 2, a through hole opened inside the support block 17, a vacuum bag 15 fitted on the lower side of the outer surface of the support block 17, and a control switch 16 fixedly connected to the front surface of the vacuum cylinder 2. The input terminal of control switch 16 is electrically connected to an external power source. A fan 11 is fixedly connected to the right side of the upper surface of the base 1. The air inlet of the fan 11 is connected to the dust collection cylinder 2 through an exhaust pipe 6. A filter screen 10 is fixedly connected to the left end of the exhaust pipe 6. The input terminal of the fan 11 is electrically connected to the output terminal of control switch 16. Place the dust collection head 4 in a suitable position, operate control switch 16, and start the fan 11. The vortex fan 11 draws out the air inside the dust collection cylinder 2 through the exhaust pipe 6, causing the air inside the dust collection cylinder 2 to be drawn out. A negative pressure is generated, which draws dust and debris through the suction head 4, through the suction pipe 3, and into the dust bag 15. A sealed access door 5 is hinged to the left side of the outer surface of the base 1. A sealing rubber gasket is fixedly connected to the connection between the outer surface of the sealed access door 5 and the dust collection cylinder 2. A fixing block 12 is fixedly connected to the rear side of the sealed access door 5. A slot is provided on the upper side of the interior of the fixing block 12. An insert block 13 is slidably connected inside the dust collection cylinder 2 and is inserted into the slot. The upper surface of the insert block 13... A spring 14 is fixedly connected between the surface and the inner wall of the dust collection cylinder 2. When the dust inside the dust collection bag 15 accumulates to a certain extent, the insert block 13 is pushed upward, the spring 14 retracts, the insert block 13 leaves the slot, and the fixed block 13 is pulled, so that the sealed inspection door 5 rotates around the hinge, thereby opening the sealed inspection door 5. A protective shell 7 is fixedly connected to the right side of the upper surface of the base 1. A handle 8 is fixedly connected to the right side of the upper surface of the protective shell 7. An air outlet is opened on the front surface of the protective shell 7, and a fixing mechanism 9 is also included.

[0026] Fixing mechanism 9 includes a fixing base 901, a sliding rod 902, a semi-circular clamping rod 903, and a semi-circular rubber pad 904. The fixing base 901 is fixedly connected to the front and rear sides of the inner surface of the vacuum cleaner 2. The sliding rod 902 is slidably connected inside the fixing base 901. The semi-circular clamping rod 903 is fixedly connected to one end of the sliding rod 902 near the middle of the vacuum cleaner 2. The semi-circular rubber pad 904 is fixedly connected to the inner arc surface of the semi-circular clamping rod 903. Fixing mechanism 9 also includes a second sliding rod 905, a connecting rod 906, a spring 907, and a movable base 908. The second sliding rod 905 is slidably connected to the front and rear sides of the inner surface of the vacuum cleaner 2. (The second sliding rod 905 is slidably connected to the rectangular...) Inside the slide groove, a telescopic rod can be provided between the upper end of the slide rod 2 905 and the bottom surface of the vertically adjacent fixed seat 901. The telescopic rod is located inside the spring 1 907. The telescopic rod ensures that the distance between the upper end of the slide rod 2 905 and the bottom surface of the vertically adjacent fixed seat 901 changes, while also effectively limiting the vertical extension and retraction of the spring 1 907. A connecting rod 1 906 is rotatably connected between the side of the slide rod 2 near the middle of the vacuum cleaner 2 and the lower surface of the slide rod 1 902 on the same side. A spring 1 907 is fixedly connected between the upper surface of the slide rod 2 905 and the lower surface of the fixed seat 901 on the same side. A connecting rod 2 is fixedly connected between the two slide rods 2 905. A movable seat 908 is slidably connected to the lower surface of the vacuum cleaner 2. Installed in conjunction with connecting rod 2, the fixing mechanism 9 also includes a slider 909, a spring 910, and a limiting groove 911. The slider 909 is slidably connected to the inside of the movable seat 908. Symmetrically distributed springs 910 are fixedly connected between the stepped surface of the slider 909 and the inner wall of the movable seat 908. A limiting block is fixedly connected to the lower surface of the slider 909. A limiting groove 911 is opened on the lower inner surface of the vacuum cleaner 2. The limiting block is engaged in the limiting groove 911. Pulling the slider 909 upward causes the spring 910 to relax, causing the limiting block to separate from the limiting groove 911. At this time, pulling the movable seat 908 to the left (the right side of the upper surface of the movable seat 908 is inclined) causes the movable seat 908 to move to the left because the connecting rod 2 is close to the lower surface of the movable seat 908. During the operation, connecting rod 2 moves downward, causing sliding rod 2 905 to move downward. Spring 1 907 relaxes, and under the action of connecting rod 1 906, sliding rod 1 902 moves away from the center of the vacuum cleaner 2, causing semi-circular clamping rod 903 and semi-circular rubber pad 904 to move. At this time, semi-circular rubber pad 904 is no longer in close contact with vacuum bag 15, and vacuum bag 15 falls downward under gravity. Then, vacuum bag 15 is removed, and a new vacuum bag 15 is placed on the lower side of the outer surface of support block 17. At this time, the movable seat 908 is pushed backward, causing the upper surface of the movable seat 908 to press against connecting rod 2. Connecting rod 2 moves upward, causing sliding rod 2 905 to move upward. Spring 1 907 contracts, causing sliding rod 1 902 to move towards the center of the vacuum cleaner 2.The semi-circular clamping rod 903 and the semi-circular rubber pad 904 are moved towards the center of the vacuum cleaner cylinder 2, causing the semi-circular rubber pad 904 to fit tightly against the outer surface of the vacuum bag 15, thus securing the vacuum bag 15. The slider 909 is then released, the spring 910 retracts, causing the slider 909 to move downwards, driving the limiting block into the limiting groove 911, thus securing the movable seat 908, thereby completing the replacement of the vacuum bag 15.

[0027] The working principle of the automatic vacuum cleaner with convenient dust bag replacement provided by this utility model is as follows: When using this automatic vacuum cleaner with convenient dust bag replacement for vacuuming operations, place the vacuum head 4 in a suitable position, operate the control switch 16, and start the fan 11. The vortex fan 11 draws the gas out of the vacuum cylinder 2 through the exhaust pipe 6, creating a negative pressure inside the vacuum cylinder 2, thereby sucking dust and debris through the vacuum head 4, and then through the exhaust pipe 3 and the through hole into the vacuum bag 15. When the dust inside the vacuum bag 15 accumulates to a certain level... Pushing the insert block 13 upwards causes the spring 14 to retract, disengaging the insert block 13 from the slot. Pulling the fixing block 13 causes the sealed access door 5 to rotate around the hinge, thus opening the sealed access door 5. Pulling the slider 909 upwards causes the spring 910 to relax, separating the limit block from the limit groove 911. At this time, pulling the movable seat 908 to the left (the right side of the upper surface of the movable seat 908 is inclined) causes the connecting rod 2 to move downwards as the movable seat 908 moves to the left, due to the connecting rod 2 being close to the lower surface of the movable seat 908. This causes the sliding rod 905 to move downwards. As the cylinder moves downwards, spring 907 relaxes, and under the action of connecting rod 906, slide rod 902 moves away from the center of the vacuum cleaner cylinder 2, causing semi-circular clamping rod 903 and semi-circular rubber pad 904 to move. At this time, semi-circular rubber pad 904 is no longer in close contact with the vacuum bag 15, and the vacuum bag 15 falls downwards due to gravity. Then, the vacuum bag 15 is removed, and a new vacuum bag 15 is placed on the lower side of the outer surface of the support block 17. At this time, the movable seat 908 is pushed backwards, causing the upper surface of the movable seat 908 to press against connecting rod 2, and connecting rod 2 moves upwards, carrying... When the sliding rod 2 905 moves upward, the spring 1 907 contracts, causing the sliding rod 1 902 to move towards the center of the vacuum cleaner 2. This moves the semi-circular clamping rod 903 and the semi-circular rubber pad 904 towards the center of the vacuum cleaner 2, thus making the semi-circular rubber pad 904 tightly adhere to the outer surface of the vacuum bag 15, thereby fixing the vacuum bag 15. When the slider 909 is released, the spring 3 910 contracts, causing the slider 909 to move downward, causing the limiting block to insert into the limiting groove 911, fixing the movable seat 908, thereby completing the replacement of the vacuum bag 15.

[0028] It is worth noting that the fan 11 disclosed in the above embodiments is GHBH-003-34-1R7, and the control switch 16 is provided with a control button corresponding to the vortex fan 11 and used to control its switch.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
