Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a vacuum cleaner with an extendable suction inlet. Background Art

[0002] A vacuum cleaner is a widely used household appliance primarily used to remove dust and debris from floors, furniture surfaces, and other hard-to-reach areas. It uses a fan driven by an electric motor to generate a powerful airflow that sucks in dust and debris and collects it in a removable container or bag.

[0003] Most vacuum cleaners are designed for home use, and their cleaning range is adequate for the average household size. However, when faced with cleaning larger areas, existing vacuum cleaner designs have limitations. Since most common vacuum cleaners on the market only have one suction port, users need to frequently move the device to ensure every area is effectively cleaned. This not only reduces cleaning efficiency but also increases the user's physical burden and fatigue.

[0004] Therefore, in order to solve this problem, there is an urgent need to develop a vacuum cleaner with an extendable suction port to improve cleaning efficiency, reduce the labor intensity of users, and enhance the overall user experience. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a vacuum cleaner with an extendable suction port to improve cleaning efficiency, reduce the labor intensity of users, and enhance the overall user experience.

[0006] The technical solution is as follows: A vacuum cleaner with an extendable suction inlet includes a mounting plate, casters, a handle, a vacuuming assembly, a first vacuum housing, hinges, a second vacuum housing, a locking plate, a mounting base, a plug rod, and a first elastic element.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example: A vacuum cleaner with an extendable suction inlet, such as Figures 1-4As shown, the vacuum cleaner includes a mounting plate 1, casters 2, a handle 3, a vacuuming assembly 4, a first vacuuming housing 5, a hinge 6, a second vacuuming housing 7, a locking plate 8, a mounting base 9, a plug rod 10, and a first elastic element 11. A caster 2 is mounted on each of the four sides of the bottom of the mounting plate 1. A handle 3 is also mounted on the mounting plate 1, and the vacuuming assembly 4 for driving the overall operation of the vacuum cleaner is mounted on the handle 3. A dust box is mounted on the mounting plate 1, and the dust box is connected to the vacuuming assembly 4 by a connecting pipe. A first vacuuming housing 5 is also mounted at the front end of the mounting plate 1. In summary, the vacuum cleaner mainly consists of the aforementioned mounting plate 1, casters 2, a handle 3, a vacuuming assembly 4, a first vacuuming housing 5, a hinge 6, a second vacuuming housing 7, a locking plate 8, a mounting base 9, a plug rod 10, and a first elastic element 11. The vacuum cleaner is composed of basic components such as mounting plate 1, casters 2, handle 3, suction assembly 4, dust box, and first suction shell 5. Mounting plate 1 serves as the basic support platform for the entire vacuum cleaner. The casters 2 mounted around its bottom assist in the overall movement of the vacuum cleaner. The handle 3 makes the vacuum cleaner more comfortable to use. The suction assembly 4 drives the vacuum cleaner, allowing the first suction shell 5 to collect dust and grime into the connecting pipes and then into the dust box. Both ends of the first vacuum chamber 5 are equipped with hinges 6, and the other end of each hinge 6 is equipped with a second vacuum chamber 7. This allows the second vacuum chamber 7 to rotate via the hinges 6, forming a flexible suction inlet that can be unfolded or folded. When space needs to be expanded, the suction inlet area of ​​the first vacuum chamber 5 can be extended using the second vacuum chambers 7 on both sides, thus expanding the suction range to accommodate cleaning operations in large spaces. The two second vacuum chambers 7 and the first vacuum chamber 5 are connected to the vacuum assembly 4 via separate connecting pipes. The two second vacuum chambers 7 are closer to the first vacuum chamber 5... A retaining plate 8 is provided at one end, and mounting bases 9 are fixedly provided at both ends of the first vacuum cleaner shell 5. Each mounting base 9 has a through-hole and slidably provided insert rod 10 that engages with the adjacent retaining plate 8. Two slots for inserting the insert rod 10 are symmetrically provided on the retaining plate 8 to fix the position of the second vacuum cleaner shell 7 in both open and closed states, ensuring that the position of the second vacuum cleaner shell 7 is stable in each form. A first elastic element 11 is provided between the insert rod 10 and the corresponding mounting base 9. In this embodiment, the first elastic element 11 is a spring, which can provide elastic support for the reset operation of the insert rod 10.

[0020] like Figure 4 As shown, it also includes a baffle 12, which is slidably disposed through the side wall of the second vacuum housing 7. The baffle 12 is used to block the suction port of the corresponding second vacuum housing 7 and can control the opening and closing of the suction port.

[0021] like Figure 4As shown, it also includes a sliding plate 13, a guide rod 14, a stop plate 15, and a second elastic member 16. Sliding plates 13 are fixedly arranged on both the left and right sides of the baffle 12. The sliding plates 13 and the corresponding baffles 12 slide together through the second dust collection shell 7. A slot is provided in the middle of the sliding plate 13. The guide rods 14 are symmetrically arranged in the slot of the sliding plate 13. The stop plate 15 is slidably arranged between the guide rods 14 on the same side. The stop plate 15 protrudes towards the second dust collection shell 7 and is engaged with the second dust collection shell 7. The stop plate 15 slides through the corresponding sliding plate 13. The sliding plate 13 has a groove 18 to facilitate the movement of the stop plate 8. The second elastic member 16 is provided between the stop plate 15 and the sliding plate 13 on the same side. In this embodiment, the second elastic member 16 is a spring. By utilizing the synchronous operation of the baffles 12 and the sliding plates 13, the stop plate 15 can be driven into the second dust collection shell 7 to achieve the effect of fixing the position of the baffles 12.

[0022] like Figure 3 As shown, it also includes a support wheel 17. The rear side of the second vacuum cleaner shell 7 is provided with a support wheel 17 for auxiliary support. When the second vacuum cleaner shell 7 is in the unfolded state, the support wheel 17 can play an auxiliary support role, reduce ground friction, and make the vacuum cleaner easier to push.

[0023] When performing vacuuming, the size of the cleaning area should be considered to determine whether to extend the second vacuum shells 7 on both sides. If extension is required, firstly, the insert rods 10 on both sides should be moved to slide on the mounting base 9. At this time, the first elastic element 11 deforms, causing the insert rods 10 to disengage from the retaining plate 8. Next, the second vacuum shells 7 on both sides should be lowered so that they are flush with the first vacuum shell 5. Then, the insert rods 10 should be released, the first elastic element 11 should be reset, and the insert rods 10 should re-engage into the corresponding retaining plates 8, thereby fixing the position of the second vacuum shells 7. This expands the suction inlet area of ​​the first vacuum shell 5, increasing the cleaning coverage. After completing the above operations, the vacuuming assembly 4 can be activated. The first vacuum shell 5 and the second vacuum shell 7 work together to effectively adsorb dust from the ground and transport the dust to the dust box through the connecting pipe.

[0024] If it is necessary to block the suction inlet of the second vacuum housing 7 on one side, simply push the matching baffle 12 into the second vacuum housing 7. When the baffle 12 moves, it drives the abutment 15 and the sliding plate 13 into the additional vacuum housing together. As the baffle 12 is pushed forward, the abutment 15 contacts and is pressed against the second vacuum housing 7, sliding on the guide rod 14. At the same time, the second elastic member 16 deforms, ensuring that the abutment 15 smoothly enters the second vacuum housing 7. Finally, the baffle 12 is firmly abutted against the second vacuum housing 7, achieving effective sealing of a specific area.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
