Description

Technical Field

[0001] This utility model relates to the field of wireless vacuum cleaner technology, and in particular to a device that facilitates cleaning and dust removal in hotels. Background Technology

[0002] A cordless vacuum cleaner is a new type of vacuum cleaner that can perform vacuuming tasks without a power cord. Like a mobile phone, it operates via a charger, typically requiring 4-10 hours to fully charge and providing 20-30 minutes of continuous use. The cordless vacuum cleaner has a built-in drive motor; simply turn it on and it will drag itself to clean, freeing you from the constraints of a power cord. Whether cleaning floors, window crevices, or even a car, it offers complete freedom of movement.

[0003] A Chinese patent discloses a handheld vacuum cleaner (authorization announcement number CN202173358U). This patented technology features a dust collection box with the dust emptying button located near the handle of the casing. Simply pressing the dust emptying button near the handle will open the dust collection box, making it convenient to open and allowing for one-handed operation.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing dust removal devices generally lack effective extension or telescopic function design in practical applications. When users need to clean the surface of objects located at higher positions, since the equipment itself cannot freely extend to the required height, users have to use external auxiliary tools such as ladders and scaffolding to climb up and reach and clean these high areas. This situation brings great inconvenience to users and significantly increases safety risks. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology lacks an effective extension or telescopic function design. When users need to clean the surface of objects located at high positions, they need to use external auxiliary tools to climb up, which poses a safety hazard. Therefore, we propose a dust removal device that is convenient for hotel cleaning.

[0006] To achieve the above objectives, this application adopts the following technical solution: a dust removal device for easy hotel cleaning, comprising a dust collection container, a driving device installed at one end of the dust collection container, an adsorption connector installed at the other end of the dust collection container, a handle installed at the bottom of the dust collection container, a sleeve fitted around the outer diameter of the handle, an inner core rod installed on one side of the sleeve, an outer cylinder fitted around the end of the inner core rod away from the sleeve, and a shell installed at the bottom of the sleeve;

[0009] Preferably, the fixing assembly includes connecting plates disposed on both sides of the housing. A plug rod is installed on the side of the connecting plate near the housing. A slot for cooperating with the plug rod is opened on the surface of the handle. The plug rod is slidably connected to the inner diameter of the slot through a sleeve. A first trapezoidal block is installed on the opposing surfaces of the connecting plates. The first trapezoidal block is located at the end of the connecting plate away from the plug rod. A second trapezoidal block for cooperating with the first trapezoidal block is installed inside the housing. A control rod is installed on the side of the second trapezoidal block away from the first trapezoidal block. A control block is installed through the housing at the end of the control rod away from the second trapezoidal block. Sliding rods are installed on both sides of the housing. A sliding hole for cooperating with the sliding rod is opened on the surface of the connecting plate. A limit plate is installed at the end of the sliding rod away from the housing. A limit spring is sleeved on the surface of the sliding rod. The end of the limit spring near the limit plate is fixed to the limit plate, and the end of the limit spring away from the limit plate is fixed to the housing.

[0010] Preferably, a first spring is sleeved on the surface of the control rod, with one end of the first spring near the control rod fixed to the control rod and the other end of the first spring away from the control rod fixed to the outer diameter of the housing.

[0011] Preferably, the front and rear ends of the second trapezoidal block are each equipped with a first slider, and the front and rear ends of the inner cavity of the housing are each provided with a first groove that cooperates with the first slider.

[0012] Preferably, the limiting component includes a cavity formed on the surface of the inner core rod, a limiting post slidably connected inside the cavity, a second spring installed inside the cavity, the other end of the second spring being fixed to the limiting post, and a plurality of limiting through holes for cooperating with the limiting post being formed on the surface of the outer cylinder.

[0013] Preferably, the front and rear ends of the limiting post are each equipped with a second slider, and the front and rear ends of the inner cavity are each provided with a second sliding groove that cooperates with the second slider.

[0014] Preferably, a third slider is installed at both the top and bottom of the inner core rod, and a third groove is provided at both the top and bottom of the outer cylinder to cooperate with the third slider.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In this invention, when a user needs to clean the surface of an object located at a high position, the handle is inserted into the inside of the sleeve, and then the handle is fixed by the fixing component. The extension length of the inner core rod is adjusted by the sliding connection between the inner core rod and the outer cylinder, and then limited by the limiting component, thereby playing an extension role.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Reference Figures 1-6As shown, this utility model provides a technical solution: a dust removal device for easy hotel cleaning, including a dust collection container 1, a driving device 2 installed at one end of the dust collection container 1, an adsorption connector 3 installed at the other end of the dust collection container 1, a handle 4 installed at the bottom of the dust collection container 1, a sleeve 5 fitted around the outer diameter of the handle 4, an inner core rod 6 installed on one side of the sleeve 5, an outer cylinder 7 fitted around the end of the inner core rod 6 away from the sleeve 5, a housing 8 installed at the bottom of the sleeve 5, a fixing component for fixing the handle 4 installed inside the housing 8, and a limiting component for limiting the outer cylinder 7 installed at the end of the inner core rod 6 away from the sleeve 5. When the user needs to clean the surface of an object located at a high position, the handle 4 is inserted into the inside of the sleeve 5, and then the handle 4 is fixed by the fixing component. The extension length of the inner core rod 6 is adjusted by the sliding connection between the inner core rod 6 and the outer cylinder 7, and then limited by the limiting component, thereby achieving an extension function, allowing the user to work at heights without the need for external tools, reducing safety hazards.

[0026] Reference Figure 2As shown, in this embodiment: the fixing component includes connecting plates 9 disposed on both sides of the housing 8. A rod 10 is installed on the side of the connecting plate 9 closest to the housing 8. A slot 11 for cooperating with the rod 10 is opened on the surface of the handle 4. The rod 10 passes through the sleeve 5 and is slidably connected to the inner diameter of the slot 11. A first trapezoidal block 12 is installed on the opposing surfaces of the connecting plates 9, located at the end of the connecting plate 9 away from the rod 10. A second trapezoidal block 13 for cooperating with the first trapezoidal block 12 is installed inside the housing 8. A control rod 14 is installed on the side of the second trapezoidal block 13 away from the first trapezoidal block 12. A control block 15 is installed through the housing 8 at the end of the control rod 14 away from the second trapezoidal block 13. Slide rods 16 are installed on both sides of the housing 8. A sliding hole 17 for cooperating with the slide rod 16 is opened on the surface of the connecting plate 9. A limit plate 18 is installed at the end of the slide rod 16 away from the housing 8. A limit spring 19 is sleeved on the surface of the slide rod 16, located near the limit plate 18. One end of the limiting spring 19 is fixed to the limiting plate 18, and the other end of the limiting spring 19 away from the limiting plate 18 is fixed to the housing 8. Before the handle 4 is inserted into the sleeve 5, the control block 15 is pressed, causing the control rod 14 to drive the second trapezoidal block 13 to squeeze the first trapezoidal block 12. This causes the first trapezoidal block 12 to drive the insertion rod 10 to move along the slide rod 16 through the connecting plate 9. At the same time, the limiting spring 19 stores force. When the connecting plate 9 is about to contact the limiting plate 18, the handle 4 is inserted into the sleeve 5. In the middle, adjust the position, and then pull the control block 15, so that the control lever 14 drives the second trapezoidal block 13 to disengage from the first trapezoidal block 12. When the second trapezoidal block 13 disengages from the first trapezoidal block 12, the rebound force released by the limit spring 19 causes the connecting plate 9 to drive the insertion rod 10 to be inserted into the slot 11, thereby fixing the position of the grip 4. By setting the fixing component, it is convenient for the user to quickly assemble the sleeve 5 and the grip 4, thereby improving the overall work efficiency.

[0027] Reference Figure 2 As shown in this embodiment: a first spring 20 is sleeved on the surface of the control rod 14. The end of the first spring 20 near the control rod 14 is fixed to the control rod 14, and the end of the first spring 20 away from the control rod 14 is fixed to the outer diameter of the housing 8. When the control block 15 drives the second trapezoidal block 13 to disengage from the first trapezoidal block 12 through the control rod 14, the thrust generated by the first spring 20 limits the position of the control block 15, preventing the second trapezoidal block 13 from squeezing the first trapezoidal block 12 when the dust collection container 1 is in use, causing the insertion rod 10 to disengage from the slot 11, and causing the handle 4 to disengage from the sleeve 5.

[0028] Reference Figure 4As shown in this embodiment: the front end and the rear end of the second trapezoidal block 13 are both equipped with a first slider 21, and the front end and the rear end of the inner cavity of the housing 8 are both provided with a first sliding groove 22 that cooperates with the first slider 21. When the second trapezoidal block 13 moves, the sliding connection between the first slider 21 and the first sliding groove 22 plays a role in limiting and guiding the movement of the second trapezoidal block 13, preventing the second trapezoidal block 13 from deviating when it moves.

[0029] Reference Figure 5 and Figure 6 As shown in this embodiment, the limiting component includes a cavity 23 formed on the surface of the inner core rod 6. A limiting post 24 is slidably connected inside the cavity 23. A second spring 25 is installed inside the cavity 23, and the other end of the second spring 25 is fixed to the limiting post 24. Several limiting through holes 26 are formed on the surface of the outer cylinder 7 to cooperate with the limiting post 24. By pressing the limiting post 24, the limiting post 24 is inserted into the cavity 23, and at the same time, the second spring 25 is charged. When the inner core rod 6 is adjusted to a suitable position, the rebound force generated by the second spring 25 drives the limiting post 24 to be inserted into the limiting through hole 26, thereby fixing the position of the inner core rod 6. This makes it easier for the user to make corresponding adjustments according to different usage scenarios, thus making it more convenient to use.

[0030] Reference Figure 6 As shown in this embodiment: the front end and the rear end of the limiting post 24 are both equipped with second sliders 27, and the front end and the rear end of the cavity 23 are both provided with second sliding grooves 28 that cooperate with the second sliders 27. Through the sliding connection between the second sliders 27 and the second sliding grooves 28, the movement of the limiting post 24 is limited, preventing the second spring 25 from pushing the limiting post 24 to move and causing it to disengage from the inside of the cavity 23.

[0031] Reference Figure 1 As shown in this embodiment: the top and bottom of the inner core rod 6 are both equipped with a third slider 29, and the top and bottom of the outer cylinder 7 are both provided with a third sliding groove 30 that cooperates with the third slider 29. The sliding connection between the third slider 29 and the third sliding groove 30 prevents the inner core rod 6 from disengaging from the inside of the outer cylinder 7 during adjustment.

[0032] Working principle: When the user needs to clean the surface of an object located at a high position, the handle 4 is inserted into the sleeve 5. Before the handle 4 is inserted into the sleeve 5, the control block 15 is pressed, causing the control lever 14 to drive the second trapezoidal block 13 to squeeze the first trapezoidal block 12. This causes the first trapezoidal block 12 to drive the insertion rod 10 to move along the slide rod 16 via the connecting plate 9. At the same time, the limit spring 19 is charged. When the connecting plate 9 is about to contact the limit plate 18, the handle 4 is inserted into the sleeve 5 and the position is adjusted. Then, the control block 15 is pulled, causing the control lever 14 to disengage the second trapezoidal block 13 from the first trapezoidal block 12. When the two parts come into contact, the rebound force released by the limiting spring 19 causes the connecting plate 9 to drive the insert rod 10 into the slot 11, thereby fixing the position of the handle 4. By setting the fixing component, the user can quickly assemble the sleeve 5 and the handle 4, thereby improving the overall work efficiency. Then, by pressing the limiting post 24, the limiting post 24 enters the cavity 23, and at the same time, the second spring 25 stores force. When the inner core rod 6 is adjusted to the appropriate position, the rebound force generated by the second spring 25 drives the limiting post 24 to enter the limiting through hole 26, fixing the position of the inner core rod 6. This allows the user to make corresponding adjustments according to different usage scenarios, making it more convenient to use.
