Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a dust cup and a vacuum cleaner. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in a sealed shell, and absorb dust.

[0003] Existing vacuum cleaners are provided with a dust cup for collecting dust, and a filter screen and a filter hepa are provided in the dust cup. After the dust-laden gas enters the dust cup, the dust in the dust-laden gas will adhere to the outer wall surface of the filter screen and the filter hepa under the action of negative pressure suction. After the vacuum cleaner has been used for a period of time, the impurities in the dust cup increase, and the volume of the dust cup is relatively fixed, so the impurities in the dust cup cannot be compressed, thereby speeding up the frequency of cleaning the impurities in the dust cup. Summary of the invention

[0004] In order to solve the technical problem that after a vacuum cleaner has been used for a period of time, the impurities in the dust cup increase, and the volume of the dust cup is relatively fixed, so the impurities in the dust cup cannot be compressed, thereby speeding up the frequency of cleaning the impurities in the dust cup, an object of the present invention is to provide a dust cup and a vacuum cleaner.

[0005] To achieve the above objectives, an embodiment of the present invention provides a dust cup, including a cup body with open ends and an air inlet; a telescopic component arranged at one end of the cup body; and a filter component arranged at the other end of the cup body.

[0006] By fixing the telescopic component and the filter component at both ends of the cup body, the filter component can filter the impurities entering the cup body. When the cup body is full of impurities, there is no need to remove the filter component to pour out the impurities inside the cup body. The impurities inside the cup body can be compressed by pushing the telescopic component, thereby extending the time for cleaning the impurities inside the cup body and reducing the frequency of cleaning the impurities inside the cup body.

[0007] In addition, the dust cup and the vacuum cleaner in the above embodiments provided by the present invention may also have the following additional technical features: In the above technical solution, the telescopic assembly includes a telescopic part, which is fixedly connected to the end of the cup body away from the filter assembly, and a accommodating cavity is provided inside the telescopic part, and an annular groove is spaced apart outside the telescopic part; an elastic plate is fixedly connected to the end of the accommodating cavity away from the filter assembly.

[0008] By fixing a telescopic piece at one end of the cup body away from the filter assembly, the telescopic piece can be pushed into the interior of the cup body so that the elastic plate fixedly connected to the accommodating cavity can compress the impurities inside the cup body and the volume of the impurities. When the impurities inside the cup body can no longer be compressed, the impurities inside the cup body can be cleaned, thereby reducing the frequency of cleaning the impurities. In addition, the telescopic piece can be extended and retracted. When the cup body is transported, the telescopic piece can be pushed into the cup body, thereby reducing the space occupied during transportation and increasing space utilization.

[0009] In the above technical solution, the telescopic member is made of soft material.

[0010] By using a soft material for the telescopic part, it can be ensured that the telescopic part can deform normally.

[0011] In the above technical solution, a handle is fixedly connected to one end of the telescopic member away from the filter assembly.

[0012] By fixing a handle at one end of the telescopic member away from the filter assembly, the user can easily pull the telescopic member outward from the inside of the cup body, thereby reducing the difficulty of operation for the user.

[0013] In the above technical solution, the filter assembly includes a bracket, which is fixedly connected to one end of the cup body away from the telescopic part, and the bracket is ring-shaped; a filter net, which is fixedly connected to one end of the bracket close to the telescopic part; and a HEPA, which is fixedly connected to one end of the bracket away from the telescopic part.

[0014] A bracket is fixedly connected to one end of the cup body away from the telescopic member. The bracket is annular, and a filter screen and a HEPA are fixedly connected to both ends of the inner wall of the bracket to filter impurities so that the impurities remain inside the cup body.

[0015] In the above technical solution, a sealing ring is provided on the outside of the bracket.

[0016] By sleeved a sealing ring on the outside of the bracket, the sealing ring can seal the bracket to prevent impurities from being discharged to the outside of the cup body through the gap between the bracket and the inner wall of the cup body.

[0017] The invention provides a vacuum cleaner, comprising the dust collecting cup.

[0018] Additional aspects and advantages of the present invention will become apparent from the following description or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0022] Refer to the following Figures 1 to 6 A dust cup and a vacuum cleaner according to some embodiments of the present invention are described.

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a dust cup and a vacuum cleaner, including a cup body 1, a telescopic assembly and a filter assembly.

[0024] Specifically, both ends of the cup body 1 are set to be open, and an air inlet 2 is opened on the cup body 1; a telescopic component is arranged at one end of the cup body 1; and a filter component is arranged at the other end of the cup body 1.

[0025] After the vacuum cleaner sucks the gas containing impurities into the vacuum cleaner, the gas containing impurities enters the cup body 1 through the air inlet 2 opened on the cup body 1. After entering the cup body 1, the gas containing impurities moves toward the filter component. The filter component fixedly connected to one end of the cup body 1 filters the impurities, and clean air is discharged from the cup body 1. As the cup body 1 continues to work, the impurities in the cup body 1 gradually increase. When the cup body 1 is full of impurities, the telescopic component fixedly connected to the end of the cup body 1 away from the filter component can be pushed into the cup body 1. The telescopic component can compress the impurities in the cup body 1, and then the telescopic component is pulled to the outside of the cup body 1, so that the telescopic component is located at the open end of the cup body 1 away from the filter component. , and then the cup body 1 can continue to work until the impurities inside the cup body 1 can no longer be compressed, and then the telescopic component can be pulled to the end away from the filter component to form a space between the telescopic component and the cup body 1, thereby increasing the capacity of the cup body 1, and the cup body 1 can continue to work until the space enclosed by the telescopic component and the cup body 1 can no longer be squeezed. At this time, the sealing component can be removed, and the impurities inside the cup body 1 can be poured out, and then the sealing component can be installed inside the cup body 1 and it can be used again. In the above process, by continuously squeezing the impurities, the frequency of cleaning the impurities inside the cup body 1 can be reduced. At the same time, by adopting the telescopic component, when the cup body 1 is transported, the telescopic component can be pushed into the cup body 1 to improve the utilization of the space.

[0026] like Figures 1 to 4 As shown, in one embodiment of the present invention, the telescopic assembly includes a telescopic member 3, which is fixedly connected to the end of the cup body 1 away from the filter assembly, and a accommodating cavity 4 is provided inside the telescopic member 3, and an annular groove 5 is spaced apart outside the telescopic member 3; an elastic plate 6 is fixedly connected to the end of the accommodating cavity 4 away from the filter assembly.

[0027] The telescopic member 3 is made of soft material.

[0028] In the initial state, one end of the telescopic part 3 is open and fixedly connected to the end of the cup body 1 away from the sealing assembly, and the other end of the telescopic part 3 is arranged outside the cup body 1 and is in a closed state, thereby forming a accommodating cavity 4 inside the telescopic part 3. When the impurities inside the cup body 1 are compacted and cannot carry more impurities, the cup body 1 can continue to work and the impurities can enter the accommodating cavity 4, and the telescopic part 3 has the effect of increasing the storage space for impurities.

[0029] When the telescopic member 3 is in working state, it is necessary to push the telescopic member 3 toward the inside of the cup body 1. Since the telescopic member 3 is made of soft material, the telescopic member 3 can be pushed toward the inside of the cup body 1. Since annular grooves 5 are spaced apart on the outside of the telescopic member 3, the annular grooves 5 divide the telescopic member 3 into a plurality of telescopic sub-members. When the telescopic member 3 is pushed to the opening of the cup body 1 away from the bracket 8 at one end, the position of each annular groove 5 is flush with the opening of the cup body 1 away from the bracket. At this time, the middle of the cross section of the telescopic sub-member is in a folded state. Then, the power is turned on, and the gas containing impurities from the outside enters the cup body 1 through the air inlet 2. Then, the gas containing impurities passes through the filter assembly. The filter assembly filters the impurities, and the impurities remain in the cup body 1, and the clean gas is discharged from the cup body 1.

[0030] When the cup body 1 is full of impurities, the telescopic member 3 is pushed toward the filter assembly. In the process of the telescopic member 3 entering the cup body 1, an elastic plate 6 is fixedly connected to the end of the telescopic member 3 away from the bracket 8. In the initial state, the elastic plate 6 is limited by the inner wall of the telescopic member 3, and both ends of the elastic plate 6 are in a bent state. When the telescopic member 3 enters the cup body 1, the elastic plate 6 is no longer limited by the telescopic member 3, and the elastic plate 6 recovers its deformation and becomes straight, so that the elastic plate 6 can compress the impurities in the cup body 1. The impurities are compacted, and then the telescopic part 3 is pulled back to the open end of the cup body 1 away from the bracket 8. Then the cup body 1 continues to work until the impurities inside the cup body 1 can no longer be compressed. The telescopic part 3 is pulled away from the bracket 8, and the accommodating cavity 4 inside the telescopic part 3 can store impurities again, thereby increasing the storage space for impurities again. Until the accommodating cavity 4 in the telescopic part 3 is also full of impurities and can no longer be compressed, the filter assembly is disassembled, the impurities in the cup body 1 are poured out, and then the filter assembly is installed in the cup body 1.

[0031] Through the above process, the telescopic part 3 can continuously compact impurities, thereby reducing the frequency of users cleaning impurities. In addition, since the telescopic part 3 can be deformed, when the cup body 1 needs to be transported, the telescopic part 3 can be pushed into the cup body 1, thereby reducing the space of the cup body 1 and improving space utilization.

[0032] It should be noted that the telescopic member 3 is fixedly connected to the cup body 1, and the fixed connection method can be ultrasonic welding or fixing by snaps, screws, glue, etc. The cup body 1 and the telescopic member 3 can be made into an integral part, so that the cup body 1 and the telescopic member 3 have strong integrity and do not require secondary assembly; the sealing is strong, and there is generally no risk of gas leakage. In addition, the shape of the telescopic member 3 can be cylindrical, conical, truncated cone, or rectangular parallelepiped. The present application uses a truncated cone. When the telescopic member 3 is completely outside the cup body 1, the size of the telescopic member 3 gradually increases from the direction close to the sealing component, which can facilitate the user to push the telescopic member 3 into the cup body 1 and reduce the resistance of the telescopic member 3. The cone needs to be set as an open bottom surface away from the vertex. Other cylindrical and rectangular parallelepiped shapes only need to be set as open at one end.

[0033] like Figures 1 to 4 As shown, in one embodiment of the present invention, a handle 7 is fixedly connected to one end of the telescopic member 3 away from the filter assembly.

[0034] By fixing a handle 7 at one end of the telescopic member 3 away from the filter assembly, it is convenient for the user to pull the telescopic member 3 outward from the inside of the cup body 1, thereby reducing the difficulty of operation for the user.

[0035] like Figure 5 to Figure 6 As shown, in one embodiment of the present invention, the filter assembly includes a bracket 8, which is fixedly connected to the end of the cup body 1 away from the telescopic part 3, and the bracket 8 is ring-shaped; a filter net 9, which is fixedly connected to the end of the bracket 8 close to the telescopic part 3; and a HEPA 10, which is fixedly connected to the end of the bracket 8 away from the telescopic part 3.

[0036] The bracket 8 is fixedly installed in the cup body 1 at the end away from the telescopic part 3 by a buckle. The bracket 8 is annular. A filter screen 9 and a HEPA 10 are fixedly connected to the inner wall of the bracket 8 near the telescopic part 3 and the end away from the telescopic part 3 respectively. The filter screen 9 is made of stainless steel. The filter screen 9 and the HEPA 10 are used to filter impurities so that the impurities remain in the cup body 1. When the cup body 1 is full of impurities, the buckle is removed, the filter assembly can be taken out of the cup body 1, and the impurities in the cup body 1 can be poured out. Then the bracket 8 is installed in the cup body 1 by the buckle. The entire filter assembly and the connection method between the filter assembly and the cup body 1 here are prior art and will not be described in detail here.

[0037] like Figure 5 to Figure 6 As shown, in one embodiment of the present invention, a sealing ring 11 is sleeved on the outside of the bracket 8 .

[0038] By sleeved a sealing ring 11 on the outside of the bracket 8 , the sealing ring 11 can seal the bracket 8 , thereby preventing impurities from being discharged to the outside of the cup body 1 through the gap between the bracket 8 and the inner wall of the cup body 1 .

[0039] The present invention provides a vacuum cleaner comprising the dust collecting cup as described above.

[0040] The present invention has the following advantages: By adopting the telescopic component, impurities can be squeezed out, and the frequency of cleaning impurities inside the cup body 1 can be reduced. At the same time, by adopting the telescopic component, when the cup body 1 is transported, the telescopic component can be pushed into the cup body 1 to improve the utilization of space.
