Technical Field
[0001] The utility model relates to the technical field of vacuum cleaners, and more specifically, to a dust cup and HEPA connection structure of a handheld vacuum cleaner. Background Art
[0002] The vacuum cleaner is a widely used cleaning tool. The working principle of the vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generating negative air pressure in the sealed shell, thereby sucking up dust. Common vacuum cleaners can be divided into horizontal, vertical, handheld, etc. according to their structure.
[0003] In the prior art, since the dust cup directly filters the inhaled debris through the HEPA during work, larger debris such as hair, coarse particles, etc. are easily attached to the surface of the HEPA. Therefore, after the vacuum cleaner has been working for a period of time, the HEPA is easily blocked, resulting in reduced filtering effect. It is necessary to stop using the vacuum cleaner and clean the HEPA inside it in time. The dust cup of vacuum cleaners on the market is usually connected to the outer shell of the vacuum cleaner, and the HEPA is usually connected to the end cover of the vacuum cleaner motor. When the user removes the dust cup to clean the garbage, after removing the dust cup, the HEPA needs to be removed from the motor end cover. The whole operation steps are relatively cumbersome.
[0004] Therefore, it is necessary to provide a handheld vacuum cleaner dust cup and HEPA connection structure to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a handheld vacuum cleaner dust cup and HEPA connection structure to solve the problems raised in the above background technology.
[0006] The above technical objectives of the utility model are achieved through the following technical solutions:
[0007] A handheld vacuum cleaner dust cup and HEPA connection structure includes a vacuum cleaner shell, a dust cup and a HEPA assembly, wherein an air inlet is provided at one end of the dust cup away from the vacuum cleaner shell, a plurality of air outlets are provided at one end of the vacuum cleaner shell away from the dust cup, the dust cup is detachably connected to the vacuum cleaner shell, the HEPA assembly is located in the dust cup and abuts against one end of the vacuum cleaner shell facing the dust cup, and the HEPA assembly is prevented from moving away from the vacuum cleaner shell by the dust cup.
[0008] The technical solution of the utility model is further configured as follows: the HEPA assembly includes a fixing plate, a HEPA and a limiting bracket, the limiting bracket is detachably connected to the fixing plate and the HEPA is located between the two, a supporting platform for abutting against the fixing plate is fixedly connected inside the dust cup, and there is a distance between the supporting platform and one end of the dust cup facing the vacuum cleaner housing.
[0009] The technical solution of the utility model is further configured as follows: a plurality of slots are provided at the spacing, a motor end cover is fixedly connected to the vacuum cleaner housing, the motor end cover abuts against the fixing plate, and a plurality of clips matching the plurality of slots are fixedly connected to the motor end cover.
[0010] The technical solution of the utility model is further configured as follows: the limiting bracket is provided with a plurality of through holes distributed in a circular array, the fixing plate is hollow, the motor end cover is provided with a plurality of ventilation holes penetrating therethrough, and the through holes, the fixing plate and the ventilation holes together form an air intake channel.
[0011] The technical solution of the utility model is further configured as follows: a support ring is fixedly connected to the fixing plate, the limiting bracket has elastic deformation performance, and the inner diameter of the limiting bracket facing one end of the fixing plate is smaller than the outer diameter of the support ring.
[0012] The technical solution of the utility model is further configured as follows: a plurality of guide plates distributed in a ring array are fixedly connected to the outer peripheral wall of the support ring, and a plurality of embedding grooves corresponding to the plurality of guide plates are opened on the limiting bracket.
[0013] The technical solution of the utility model is further configured as follows: a plurality of clamping plates alternately arranged with a plurality of the guide plates are fixedly connected to the fixed plate, the clamping plates have elastic deformation properties, a plurality of the clamping plates are arc-shaped and there are gaps between the clamping plates and the support rings, and the thickness of the limiting bracket toward one end of the fixed plate is greater than the gap between the clamping plates and the support rings.
[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0015] Through the structural setting, the position of the HEPA component can be restricted while the dust cup is installed on the vacuum cleaner housing, so that the HEPA component can be stably filtered in the dust cup, and when the dust cup is removed for cleaning, the HEPA component will be directly detached from the vacuum cleaner housing without the need for additional disassembly, which simplifies the operation steps and makes cleaning more convenient and quick.
[0016] Through the structural setting, the limiting bracket can utilize the embedding groove to be inserted into the outer wall of the support ring along the guide plate, and through the elastic performance of the limiting bracket, the limiting bracket clamps the support ring, thereby achieving the fixing effect of the limiting bracket. This plug-in and pull-out method makes the disassembly and installation of the limiting bracket and the fixing plate more convenient, and the HEPA can be quickly taken out for cleaning or replacement.

[0024] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example
[0025] like Figures 1 to 6 As shown, the utility model provides a handheld vacuum cleaner dust cup and HEPA connection structure, comprising a vacuum cleaner shell 1, a dust cup 2 and a HEPA assembly, an end of the dust cup 2 away from the vacuum cleaner shell 1 is provided with an air inlet 3, an end of the vacuum cleaner shell 1 away from the dust cup 2 is provided with a plurality of air outlet holes 4, the dust cup 2 is detachably connected to the vacuum cleaner shell 1, the HEPA assembly is located in the dust cup 2 and abuts against the end of the vacuum cleaner shell 1 facing the dust cup 2, and the HEPA assembly is prevented from being away from the vacuum cleaner shell 1 by the dust cup 2.
[0026] like Figures 1 to 6As shown, the HEPA assembly includes a fixing plate 5, a HEPA 6 and a limiting bracket 7, the limiting bracket 7 is detachably connected to the fixing plate 5 and the HEPA 6 is located therebetween, a bearing platform 8 for abutting against the fixing plate 5 is fixedly connected inside the dust cup 2, there is a gap between the bearing platform 8 and the end of the dust cup 2 facing the vacuum cleaner housing 1, a plurality of card slots 9 are provided at the gap, a covering member for shielding part of the card slots 9 is detachably connected to the dust cup 2, a motor end cover 10 is fixedly connected to the vacuum cleaner housing 1, the motor end cover 10 abuts against the fixing plate 5, a plurality of clips 11 matching the plurality of card slots 9 are fixedly connected to the motor end cover 10, a plurality of through holes distributed in a circular array are provided on the limiting bracket 7, the fixing plate 5 is hollow, a plurality of air vents 12 passing through the motor end cover 10 are provided, and the through holes, the fixing plate 5 and the air vents 12 together form an air intake passage.
[0027] By matching the card slot 9 on the dust cup 2 with the card connector 11 on the motor end cover 10, the effect of installing and removing the dust cup 2 from the vacuum cleaner housing 1 is achieved. In this process, due to the existence of the motor end cover 10, the fixing plate 5 will move toward the inside of the dust cup 2, thereby abutting against the supporting platform 8. When the dust cup 2 is installed on the vacuum cleaner housing 1, the fixing plate 5 will be restricted by the supporting platform 8 and the motor end cover 10 and cannot move in the dust cup 2, thereby achieving the fixing effect thereof, ensuring that during the vacuuming process, the HEPA 6 between the limiting bracket 7 and the fixing plate 5 can stably perform the filtering work. When you want to remove the HEPA 6 for cleaning, you only need to remove the dust cup 2 from the vacuum cleaner housing 1 to release the restriction on the fixing plate 5, which is convenient for cleaning the HEPA 6 and the operation method is relatively simple.
[0028] like Figures 1 to 6 As shown, a support ring 13 is fixedly connected to the fixing plate 5, the limiting bracket 7 has elastic deformation performance, the inner diameter of the limiting bracket 7 facing the fixing plate 5 is smaller than the outer diameter of the support ring 13, and a plurality of guide plates 14 distributed in a ring array are fixedly connected to the outer peripheral wall of the support ring 13, and a plurality of embedding grooves 15 corresponding to the plurality of guide plates 14 are provided on the limiting bracket 7, and a plurality of clamping plates (not shown in the figure) alternately arranged with the plurality of guide plates 14 are fixedly connected to the fixing plate 5, and the clamping plates have elastic deformation performance, and the plurality of clamping plates are arc-shaped and have gaps with the support ring 13, and the thickness of the limiting bracket 7 facing the fixing plate 5 is greater than the gap between the clamping plates and the support ring 13.
[0029] The limiting bracket 7 can be aligned with the guide plate 14 on the support ring 13 through the embedding groove 15 provided at one end thereof and the limiting bracket 7 can be mounted on the support ring 13 along the guide plate 14. Since the limiting bracket 7 has elastic deformation properties and the inner diameter of the limiting bracket 7 facing the fixed plate 5 is smaller than the outer diameter of the support ring 13, the support ring 13 can exert a spreading force on the inner wall of the limiting bracket 7, thereby achieving the effect of fixing it. A clamping plate can also be added to the fixed plate 5 to clamp the outer wall of the limiting bracket 7 through the clamping plate to further ensure the fixing effect. When you want to disassemble the HEPA 6 for cleaning, you can also directly pull out the limiting bracket 7, and the operation method is relatively simple.
[0030] like Figures 1 to 6 As shown, after the vacuum cleaner has been used for a period of time, since the debris in the dust cup 2 will continue to accumulate, it is necessary to disassemble the dust cup 2 to clean the inside of the dust cup 2 and the HEPA 6. At this time, the connection between the clamp 11 and the slot 9 can be manually released to allow the dust cup 2 to be detached from the vacuum cleaner housing 1. The HEPA component is located on the supporting platform 8 in the dust cup 2 and can be taken out by tipping or carrying. Finally, you only need to unplug the limiting bracket 7 from the fixing plate 5 to replace or clean the HEPA 6 to complete the cleaning operation of the vacuum cleaner. There is no need to disassemble the HEPA component additionally, and the operation is relatively simple and convenient.
[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
