Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a locking structure for a dust cup assembly of a horizontal vacuum cleaner. Background Art

[0002] A vacuum cleaner uses an electric motor to drive the blades to rotate at high speed, creating negative air pressure in a sealed shell to absorb dust.

[0003] The dust cup assembly locking structure of the dust cup type horizontal vacuum cleaner currently on the market uses a hook to lock the dust cup assembly in the up and down directions. To achieve locking in the front and back directions at the same time requires a larger space, which affects the space that the dust cup assembly can accommodate dust. There is room for improvement in the prior art. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a locking structure for the dust cup assembly of a horizontal vacuum cleaner, which realizes the locking effect of the dust cup assembly in the up and down and front and back directions through a hook within a limited space, thereby greatly increasing the space that the dust cup assembly can accommodate dust and increasing the dust holding capacity of the vacuum cleaner.

[0005] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows: a locking structure of a dust cup assembly of a horizontal vacuum cleaner, comprising a body assembly, a middle frame assembly and a dust cup assembly, wherein a card-embedded assembly for fixing the dust cup assembly is arranged between the dust cup assembly and the body assembly, and the card-embedded assembly comprises a release button, a button lever and a spring sheet for supporting the button lever; the cross-section of the button lever is an L-shaped structure, comprising a horizontal surface abutting against the spring sheet and a vertical surface abutting against the dust cup assembly, and the horizontal surface is rotatably connected to the middle frame assembly; the release button comprises a column passing through the horizontal surface, a press cap and a hook are arranged at one end of the column, and the hook is clamped on the middle frame assembly; a positioning point for clamping the dust cup assembly is arranged on the body assembly, and the dust cup assembly has an abutment block arranged corresponding to the vertical surface and a clamping groove arranged corresponding to the positioning point, and the abutment block is clamped between the middle frame assembly and the vertical surface.

[0006] By adopting the above technical solution, when assembling the components, first install the spring sheet and the button lever into the middle frame assembly so that the spring sheet abuts against the horizontal plane, then install the release button on the middle frame assembly, make the column pass through the horizontal plane, and then fix the middle frame assembly to the body assembly; when the dust cup assembly has not been assembled, the hook is in a state of hooking the middle frame assembly, at this time, the button lever is in a tilted state under the action of the spring sheet, and when the dust cup assembly is installed in the whole machine, the dust cup assembly abuts against the vertical surface, causing the button lever to rotate, and at the same time the column and the spring sheet move downward The movement allows the dust cup assembly to move downward smoothly. When the card slot of the dust cup assembly is placed on the positioning point, the hook of the dust cup release button moves upward and hooks the middle frame assembly again. At the same time, the button lever rebounds to a tilted state under the action of the spring so that the vertical surface remains in contact with the dust cup assembly, thereby clamping the dust cup assembly. The locking structure in this scheme is more compact, and a card hook is used to achieve the locking effect of the dust cup assembly in the up and down and front and back directions within a limited space, which greatly increases the space that the dust cup assembly can accommodate dust and increases the dust holding capacity of the vacuum cleaner.

[0007] The present invention is further configured such that: the push cap includes an extension portion abutting against the horizontal plane.

[0008] By adopting the above technical solution, the user can press the button lever in the tilted state by squeezing the push cap, thereby assisting the dust cup assembly in squeezing the button lever, thereby facilitating the dust cup assembly to enter the body assembly.

[0009] The present invention is further configured as follows: the dust cup assembly includes a cup body and a cup cover, and the abutment block includes a first abutment block integrally formed with the cup body and a second abutment block integrally formed with the cup cover.

[0010] By adopting the above technical solution, the cup body and the cup lid are separately arranged to facilitate users to clean the dust inside the cup body, and the cup body and the cup lid are respectively kept in contact with the button lever through the first abutment block and the second abutment block, ensuring that the cup lid can be fixed on the cup body, preventing the risk of separation of the cup lid and the cup body during use.

[0011] The present invention is further configured as follows: the cross section of the spring sheet is in a V-shaped structure, one side of the spring sheet abuts against the middle frame assembly, and the other side abuts against the horizontal plane.

[0012] By adopting the above technical solution, the V-shaped spring piece can provide elastic force to the button lever by twisting, which can reduce the space occupied by the spring piece in the middle frame body and further reduce the space occupied by the locking structure in the middle frame assembly.

[0013] The present invention is further configured such that: the angle of the spring piece is between 45° and 65°.

[0014] By adopting the above technical solution, an angle of not less than 45° can ensure that the button lever has a sufficient tilting angle to ensure that the button lever can press against the dust cup assembly; an angle of not more than 65° can avoid the button lever from tilting too much to avoid the button lever from flipping over when the dust cup assembly enters.

[0015] The present invention is further configured as follows: ribs extend from the column, and the ribs are respectively located on both sides of the hook.

[0016] By adopting the above technical solution, the ribs improve the structural strength of the column, avoiding the separation of the hook and the middle frame assembly due to deformation of the column caused by movement and vibration of the body assembly during use, thereby greatly improving the stability of the locking structure.

[0017] The present invention is further configured such that: the spring sheet is provided with a first passage for the column to pass through.

[0018] By adopting the above technical solution, interference between the spring piece and the column is avoided, and the space utilization rate of the locking structure is further improved. During use, the column can also limit the displacement of the spring piece.

[0019] The present invention is further configured as follows: a second channel in a cross-shaped structure is provided on the horizontal plate.

[0020] By adopting the above technical solution, the position of the horizontal plate is further limited by the column and the rib plate to prevent the button lever from being separated from the middle frame assembly.

[0021] The present invention is further configured as follows: a guide groove is provided on the middle frame assembly, and a clamping block corresponding to the guide groove is provided on the dust cup assembly.

[0022] By adopting the above technical solution, the dust cup assembly can be guided into the middle frame assembly and the body assembly through the guide groove and the block, and a limiting effect can be achieved.

[0023] The present invention is further configured as follows: the guide groove is arranged obliquely, the clamping block and the guide groove are arranged obliquely correspondingly, and the inclination angle between the guide groove and the vertical plane is between 5 and 10 degrees.

[0024] By adopting the above technical solution, the dust cup assembly moves toward one side of the button lever while squeezing the button lever downward, and forms a horizontal limit after the hook is fixed on the middle frame assembly again.

[0025] In summary, the present invention has the following technical effects:

[0026] 1. The space occupied by the locking structure of the dust cup assembly is greatly reduced, the capacity of the dust cup assembly is greatly increased, and the number of times the user cleans the dust cup assembly is reduced;

[0027] 2. Greatly improve the space utilization of horizontal vacuum cleaners and reduce the space occupied by the locking structure;

[0028] 3. It is convenient for users to disassemble and install the dust cup assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] A locking structure for a dust cup assembly of a horizontal vacuum cleaner, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a body component, a middle frame component and a dust cup component. A card embedding component for fixing the dust cup component is provided between the dust cup component and the body component. Figure 4 and Figure 8 As shown, the card embedding assembly includes a release button, a button lever and a spring for supporting the button lever; the cross-section of the button lever is an L-shaped structure including a horizontal surface abutting against the spring and a vertical surface abutting against the dust cup assembly, and the horizontal surface is rotatably connected to the middle frame assembly through a rotating shaft; Figure 7 As shown, the release button includes a column passing through the above-mentioned horizontal plane, one end of the column is provided with a button cap and a hook, and the hook is connected to the middle frame assembly; Figure 6 As shown, the body assembly is provided with a positioning point for clamping the dust cup assembly, combined with Figure 5 As shown, the dust cup assembly has an abutment block arranged corresponding to the vertical surface and a card slot arranged corresponding to the positioning point, and the abutment block is clamped between the middle frame assembly and the vertical surface; when assembling the components, first install the spring sheet and the button lever into the middle frame assembly so that the spring sheet abuts against the horizontal surface, and then install the release button on the middle frame assembly so that the column passes through the horizontal surface, and then fix the middle frame assembly to the body assembly; when the dust cup assembly has not been assembled, the card hook is in a state of hooking the middle frame assembly, and at this time, the button lever is in a tilted state under the action of the spring sheet, and when the dust cup assembly is installed into the whole machine, the dust cup assembly abuts against the vertical surface, causing the button lever to rotate, and at the same time, the column and the spring sheet move downward to make the dust cup assembly move downward smoothly, and when the card slot of the dust cup assembly is sleeved on the positioning point, the hook of the dust cup release button moves upward and hooks the middle frame assembly again, and at the same time, the button lever rebounds to a tilted state under the action of the spring sheet so that the vertical surface remains in contact with the dust cup assembly, thereby clamping the dust cup assembly.

[0042] Furthermore, in order to facilitate squeezing the button lever when installing the dust cup assembly and make it easy for the dust cup assembly to enter the body assembly, the push cap includes an extension portion that abuts the horizontal plane. When the user squeezes the extension portion downward, it can press down the button lever in the tilted state, thereby assisting the dust cup assembly to squeeze the button lever, making it easier for the dust cup assembly to enter the body assembly.

[0043] In this solution, the dust cup assembly includes a cup body and a cup lid. The user can clean the dust in the cup body after opening the cup lid. The abutment block includes a first abutment block integrally formed with the cup body and a second abutment block integrally formed with the cup lid. The cup body and the cup lid can be fixed after the button lever abuts against the abutment block, so that the cup lid can only be opened after the dust cup assembly falls off the body assembly, thereby avoiding the risk of the cup lid falling during use.

[0044] like Fig. 9As shown, in order to make the structure of the embedded component more compact, the cross-section of the spring sheet is V-shaped, one side of the spring sheet abuts against the middle frame component, and the other side abuts against the horizontal plane; the angle of the spring sheet is between 45 and 65°, and an angle of not less than 45° can ensure that the button lever has a sufficient tilting angle to ensure that the button lever can be tightly pressed against the dust cup component; an angle of not more than 65° can avoid the button lever from tilting too much, and avoid the button lever from flipping over when the dust cup component enters.

[0045] like Figure 7 As shown, in order to provide structural strength for the column in this solution, ribs are extended on the column, and the ribs are respectively located on both sides of the hook. The load strength of the column is increased by the ribs to prevent the hook from being separated from the middle frame assembly due to shaking or deformation of the column.

[0046] In order to make the structure of the embedded component more compact, a first channel for the column to pass through is opened on the spring sheet; and a second channel in a cross-shaped structure is opened on the horizontal plate.

[0047] In order to reduce damage to the embedded components caused by human operational errors, a guide groove is opened on the middle frame assembly, and a card block corresponding to the guide groove is provided on the dust cup assembly; the above-mentioned guide groove is inclined, and the card block and the guide groove are inclined correspondingly, and the inclination angle between the guide groove and the vertical plane is between 5 and 10°.

[0048] It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
