Description
本发明涉及小家电领域，特别涉及一种用于海帕自清洁式吸尘器的风道快速切换结构。The invention relates to the field of small household appliances, and in particular to a quick-change structure of an air duct for a Hypa self-cleaning vacuum cleaner.
吸尘器的工作原理是，利用电动机带动叶片高速旋转，在密封的壳体内产生空气负压，吸取带有尘屑的地毯、地板、墙体等物体表面，而尘屑随着空气被一同吸入尘气分离组件中后，尘屑被尘气分离组件中的海帕所过滤并被集尘桶所收集，过滤后的洁净空气则被排除吸尘器机体外。The working principle of a vacuum cleaner is to use a motor to drive the blades to rotate at a high speed, generating negative air pressure in a sealed housing, and sucking the surfaces of carpets, floors, walls and other objects with dust, and the dust is sucked into the dust with the air. After separating the components, the dust is filtered by the Hypa in the dust separation component and collected by the dust collecting bucket, and the filtered clean air is excluded from the outside of the vacuum cleaner.
海帕在工作一段时间后，其位于集尘桶一侧的表面上吸附有大量尘屑，尘屑大量附着在海帕表面会将海帕表面的微小过滤筛孔堵塞，进而影响海帕的过滤能力，目前市场上的吸尘器产品存在以下几个问题：一方面，现有的吸尘器缺少对海帕进行自清洁的功能，一般发生海帕堵塞问题后，要么拆机后对海帕进行拍打除屑，要么拆机后直接对海帕进行换新，无论哪种方式都将花费大量清理时间，而后者将直接导致耗材的替换成本；另一方面，现有的吸尘器即使设有海帕自清洁功能，也是采用的电磁继电器结构，即采用机械式敲打海帕，使得海帕表面的尘屑抖落至集尘桶中，这种除屑方式使得海帕表面的尘屑清理得不彻底，产品结构较复杂，且使用成本较高。After working for a period of time, Hypa has attracted a large amount of dust on its surface on the side of the dust collector. A large amount of dust adhered to the surface of Hypa will block the tiny filtering sieve on the surface of Hypa, which will affect the filtration of Hypa Capacity, the current vacuum cleaner products on the market have the following problems: On the one hand, the existing vacuum cleaners lack the function of self-cleaning Hypa. Generally, after the Hypa clogging problem occurs, the Hypa will be beaten to remove debris. Either replace the Hypa directly after disassembling it, either way will take a lot of cleaning time, and the latter will directly lead to the replacement cost of consumables; on the other hand, the existing vacuum cleaner even has Hypa self-cleaning function The structure of the electromagnetic relay is also adopted, that is, mechanically hitting the Hypa, so that the dust on the surface of the Hypa is shaken into the dust collecting bucket. This kind of debris removal method makes the dust on the surface of the Hypa not completely cleaned, and the product structure It is more complicated and the use cost is higher.
为此，我司开发了一种自清洁式吸尘器，其采用两个风道及两个电动机，将海帕一分为二，两个电动机同时工作，使得一半的海帕在正向抽风过滤尘屑时，另一半的海帕则进行反向吹风除尘，而现有风道切换结构，一方面体积臃肿、结构复杂，另一方面，使得风道在切换过程中风能损耗过大，导致噪音大、风力小等问题。有鉴于此，实有必要开发一种用于海帕自清洁式吸尘器的风道快速切换结构，用以解决上述问题。To this end, our company has developed a self-cleaning vacuum cleaner, which uses two air ducts and two motors to divide the Hypa into two. The two motors work at the same time, so that half of the Hypa is filtering air in the forward direction to filter the dust. At the time of cutting, the other half of the Hypa will perform reverse blowing dust removal, and the existing air duct switching structure is bloated and complex on the one hand, and the wind energy is excessively lost during the air duct switching process, resulting in loud noise. , Small wind and other issues. In view of this, it is really necessary to develop a fast air duct switching structure for a Hypa self-cleaning vacuum cleaner to solve the above problems.

参照图2及图3，左导流风道1312在其风道末端处的口径尺寸小于前壁板1351与后壁板1352之间的间距，以使得左挡风板181向左导流风道1312内部转动的趋势被左导流风道1312所限制。2 and 3, the diameter of the left diversion duct 1312 at the end of the duct is smaller than the distance between the front wall panel 1351 and the rear wall panel 1352, so that the left wind deflector 181 directs the left diversion duct. The tendency of internal rotation of 1312 is restricted by the left diversion duct 1312.
进一步地，右导流风道1322在其风道末端处的口径尺寸小于前壁板1351与后壁板1352之间的间距，以使得右挡风板182向右导流风道1322内部转动的趋势被右导流风道1322所限制。Further, the caliber size of the right diversion air duct 1322 at the end of the air duct is smaller than the distance between the front wall plate 1351 and the rear wall plate 1352, so that the right wind deflector 182 rotates inside the right diversion air duct 1322. The trend is limited by the right diversion duct 1322.
在优选的实施方式中，前壁板1351的顶部开设有第一左安装槽1351a及第一右安装槽1351b，后壁板1352的顶部开设有第二左安装槽1352a及第二右安装槽1352b，所述左转轴及右转轴分别架设于第一左安装槽1351a与第二左安装槽1352a之间及第一右安装槽1351b与第二右安装槽1352b之间。In a preferred embodiment, the top of the front wall plate 1351 is provided with a first left mounting groove 1351a and a first right mounting groove 1351b, and the top of the rear wall plate 1352 is provided with a second left mounting groove 1352a and a second right mounting groove 1352b. The left and right rotating shafts are respectively erected between the first left mounting groove 1351a and the second left mounting groove 1352a, and between the first right mounting groove 1351b and the second right mounting groove 1352b.
工作原理：working principle:
参照图2，左导流风道1312中的气流沿箭头A方向流动，右导流风道1322中的气流沿箭头B方向流动，左挡风板181及右挡风板182在未受到气流推动作用时，均呈自由下垂之势，而同一时间只允许左导流风道1312中的气流流动或者右导流风道1322中的气流流动，参照图3，左导流风道1312的风道末端分别设有左前限位板1354及左后限位板1356，左挡风板181在自然下垂时，其向左旋转的趋势被左前限位板1354及左后限位板1356所限制；右导流风道1322的风道末端分别设有右前限位板1355及右后限位板1357，右挡风板182在自然下垂时，其向右旋转的趋势被右前限位板1355及右后限位板1357所限制。2, the airflow in the left airflow duct 1312 flows in the direction of arrow A, the airflow in the right airflow duct 1322 flows in the direction of arrow B, and the left air baffle 181 and the right air baffle 182 are not pushed by the airflow. When acting, they are all free to sag, and only the airflow in the left diversion air duct 1312 or the air flow in the right diversion air duct 1322 is allowed at the same time. Referring to FIG. 3, the air duct of the left diversion air duct 1312 The front end is provided with a left front limit plate 1354 and a left rear limit plate 1356. When the left windshield 181 sags naturally, its leftward rotation tendency is restricted by the left front limit plate 1354 and the left rear limit plate 1356. Right The air duct ends of the diversion air duct 1322 are respectively provided with a right front limit plate 1355 and a right rear limit plate 1357. When the right windshield 182 sags naturally, its rightward rotation trend is determined by the right front limit plate 1355 and the right rear Limited by limit plate 1357.
以右导流风道1322与汇流口1353相连通为例来进一步阐述。参照图3， 左导流风道1312没有气流流动，左挡风板181呈自然下垂之势，右导流风道1322的气流沿箭头B方向流动，右挡板182被右导流风道1322的气流推动至水平状态，而左挡风板181因为其向左旋转的趋势被左前限位板1354及左后限位板1356所限制，使得左导流风道1312被左挡风板181所封堵，流入风道切换通道135的气流被左挡风板181所阻挡，只能流入汇流口1353中。左导流风道1312与汇流口1353相连通的原理与上述类似，在此不再赘述。Take the right diversion duct 1322 and the junction 1353 as an example to further explain. Referring to FIG. 3, the left diversion duct 1312 has no air flow, the left wind deflector 181 has a natural drooping tendency, the air flow of the right diversion duct 1322 flows in the direction of arrow B, and the right baffle 182 is deflected by the right diversion duct 1322 The airflow is pushed to a horizontal state, and the left wind deflector 181 is restricted by the left front limit plate 1354 and the left rear limit plate 1356 because of its tendency to rotate to the left, so that the left diversion air duct 1312 is left by the left wind deflector 181. The airflow flowing into the air channel switching channel 135 is blocked by the left wind deflector 181 and can only flow into the confluence port 1353. The principle that the left diversion duct 1312 communicates with the junction 1353 is similar to the above, and is not repeated here.
