Abstract

The present invention relates to a mop drying mechanism by centrifugation comprising a set of reduction gears. It is actuated by vertical descending pulses that are applied to the mop (1) and push the basket (2). Consequently, the basket (2) drives the rack system (3), which activates the bevel gear (4). This changes the rotational movement to the horizontal, thus causing the engagement of the lower spur gear (5). The ratchet system (7) is incorporated in the connection between this and the upper spur gear (6), limiting the upper spur gear (6) to a unidirectional rotation. The toothed shaft (8) of the latter is connected to the basket (2) and limits the basket (2) to a vertical translational movement, allowing it to rotate simultaneously, and closing the mechanism. This mechanism can be fabricated since it is mainly composed of injected plastic parts.

Estado da técnica State of the art

As esfregonas têm como finalidade limpar e remover líquidos, sujidade e poeiras, de superfícies. Sendo este utensílio muito usado no meio industrial e doméstico. É um produto que tem sofrido constantes melhoramentos, tanto a nível tecnológico, nos mecanismos de secagem da esfregona e nos próprios filamentos da esfregona que absorvem a água, como nos custos de produção.  Mops are intended to clean and remove liquids, dirt and dust from surfaces. Being this utensil much used in the industrial and domestic environment. It is a product that has undergone constant improvements, both technologically, in the drying mechanisms of the mop and in the mop filaments themselves that absorb water, as well as in production costs.

Atualmente, o mecanismo de secagem de esfregonas mais eficaz e eficiente atua por cent ifugação, pela rotação da esfregona e dc balde a velocidades elevadas. Quando comparado cora mecanismos anteriores, como espremer a esfregona manualmente ou torcê-la e comprimi-la através do cabo contra um espremedor, esta solução implica menos força de atuação e possibilita maior rapidez e eficácia para secar a esfregona. Este mecanismo possibilita também uma maior higiene e segurança, afastando o utilizador do contacto direto com químicos dos produtos de limpeza e com a sujidade a limpar, como por exemplo, objetos cortantes que estejam nos filamentos. Adicionalmente, os custos de produção do mecanismo são inferiores aos custos dos produtos já existentes no mercado. Currently, the most effective and efficient mop drying mechanism operates by centrifugation, by rotating the mop and bucket at high speeds. When compared to previous mechanisms, such as squeezing the mop manually or twisting it and compressing it through the cable against a wringer, this solution implies less force of actuation and allows for greater speed and effectiveness to dry the mop. This mechanism also enables greater hygiene and safety by removing the user from direct chemical contact with cleaning products and dirt to be cleaned, such as sharp objects in the filaments. In addition, the production costs of the are lower than the costs of products already on the market.

Existem já vários tipos de mecanismos de secagem de esfregonas por centrifugação. No caso do produto descrito no pedido de patente N° US2012192373AÍ, o mecanismo de rotação está situado no interior do cabo da esfregona e é composto por diversos componentes, em que o principal responsável pela rotação é um veio roscado. Este mesmo mecanismo já sofreu posteriores melhoramentos com a adição de engrenagens desmultiplícadoras, com o objetivo de reduzir a carga a aplicar no seu funcionamento. Exemplos destes são os modelos de utilidade N° CN202235236U e N CN205458515U. Contudo, este tipo de mecanismo, mesmo na sua forma mais básica, ainda tem custos de produção elevados para o mercado onde está inserido. Estes custos devem-se aos materiais usados e, principalmente, ao elevado custo de montagem.  There are already several types of mechanisms for drying mops by centrifugation. In the case of the product described in the patent application No. US2012192373A, the rotation mechanism is located inside the mop handle and is composed of several components, the main one responsible for the rotation being a threaded shaft. This same mechanism has already undergone further improvements with the addition of gearing gears, in order to reduce the load to be applied in its operation. Examples of these are Utility Models No. CN202235236U and N CN205458515U. However, this type of mechanism, even in its most basic form, still has high production costs for the market where it is embedded. These costs are due to the materials used and, mainly, to the high cost of assembly.

Existe também outro importante tipo de mecanismo de rotação, que inclui um pedal como atuador de engrenagens desmultiplícadoras impulsionadoras da rotação do cesto e da esfregona. Exemplos destes são o pedido de patente N° US20100064469A1 e o modelo de utilidade N° CN203987918U. Na sua forma mais básica, este tipo de mecanismo de rotação melhora os custos de montagem em relação ao mecanismo anteriormente descrito. No entanto, o seu manuseamento por pedal não é o mais acessível a qualquer utilizador, exigindo algum equilíbrio. Outros fatores negativos são o espaço exterior ao balde que é ocupado pelo pedal, dificultando a arrumação em espaços mais reduzidos, assim como o facto de ser mais propício a tombar durante os acíonamentos do pedal, se o balde não estiver devidamente cheio, There is also another important type of rotation mechanism, which includes a pedal as a multi-engined gearing actuator driving the rotation of the basket and the mop. Examples of these are the patent application No. US20100064469A1 and the utility model No. CN203987918U. In its most basic form, this type of rotation mechanism improves assembly costs relative to the previously described mechanism. However, its pedal handling is not the most accessible to any user, requiring some balance. Other negative factors are the space outside the bucket that is occupied by the pedal, making it difficult to tidy up in smaller spaces, as well as being more likely to tip over during pedal acceleration if the bucket is not properly filled,

A presente invenção proporciona a redução dos custos de produção, contendo na sua maioria peças fabricadas por injeçâo plástica e proporcionando uma fácil montagem do mecanismo de rotação, podendo ser quase totalmente montada pelo próprio utilizador. O mecanismo ocupa uma área bastante reduzida, situando-se apenas no interior do balde, debaixo do cesto. 0 seu manuseamento é bastante simplificado, tendo o utilizador apenas que aplicar carga no cabo da esfregona no sentido descendente. As engrenagens desmult iplicadoras resultam numa carga de atuação inferior â dos mecanismos já existentes . The present invention provides for the reduction of production costs, most of which are made by plastic injection and providing an easy assembly of the rotation mechanism, and can be almost completely assembled by the user. The mechanism occupies a very small area, located only inside the bucket, under the basket. Its handling is greatly simplified, with the user only having to apply load on the mop handle in the downward direction. The demultiplexing gears result in a lower operating load than that of the existing mechanisms.

Sumário da invenção SUMMARY OF THE INVENTION

A presente invenção refere-se a um mecanismo de secagem de uma esfregona por centrif gação motora. Este mecanismo inclui uma esfregona (1), uma base do mecanismo (9), um cesto (2), um sistema de cremalheira (3), uma engrenagem cónica (4), uma engrenagem cilíndrica inferior (5), uma engrenagem cilíndrica superior (6) e um sistema de roquete (7). O movimento descendente da esfregona (1) empurra o cesto (2) para baixo. Consequentemente, o cesto (2) aciona o sistema de cremalheira (3) que por sua vez está ligado à engrenagem cónica (4). A engrenagem cónica (4) altera o movimento de rotação da vertical para a horizontal, provocando assim, o engrenamento da engrenagem cilíndrica inferior (5). Na ligação entre a engrenagem cilíndrica inferior" (5) e a engrenagem cilíndrica superior (6) está incorporado o sistema de roquete (7), limitando a engrenagem cilíndrica superior (6) a uma rotação unidirecional . A engrenagem cilíndrica superior (6) está ligada ao cesto (2), fechando o mecanismo de secagem de uma esfregona por centrifugação motora. Esta ligação é feita pelo veio dentado (8) que limita o cesto (2) a um movimento translacionai vertical, permitindo a sua rotação em simultâneo. Todo o mecanismo, à exceção da esfregona (1) e do cesto (2), é compactado no interior do balde (10) . A complexa desmultíplicação das engrenagens é inevitável para que o cesto (2) gire o suficiente para realizar a secagem dos filamentos da esfregona, com poucos movimentos descendentes da esfregona com uma baixa carga de atuação para os efetuar. The present invention relates to a mechanism for drying a mop by motor centrifugation. This mechanism includes a mop 1, a base of the mechanism 9, a basket 2, a rack system 3, a bevel gear 4, a lower cylindrical gear 5, an upper cylindrical gear (6) and a ratchet system (7). The downward movement of the mop (1) pushes the basket (2) downwards. Consequently, the basket (2) drives the rack system (3) which in turn is connected to the bevel gear (4). The conical gear 4 alters the rotation movement from the vertical to the horizontal, thus causing the engagement of the lower cylindrical gear 5. In the connection between the lower cylindrical gear "5 and the upper cylindrical gear 6 the ratchet system 7 is incorporated, limiting the upper cylindrical gear 6 to a unidirectional rotation. The upper cylindrical gear 6 is connected to the basket 2, closing the drying mechanism of a mop by motor centrifugation.This connection is made by the toothed shaft 8 which limits the basket 2 to a vertical translational movement, allowing it to rotate simultaneously. the mechanism other than the mop 1 and the basket 2 is compacted within the pail 10. The complex demultiplexing of the gears is unavoidable so that the basket 2 rotates sufficiently to effect the drying of the filaments of the mop, with few descending movements of the mop with a low actuation load to effect them.

Descrição detalhada da invenção Detailed description of the invention

A presente invenção, representada nas figuras de 1 a 8, refere-se a um mecanismo de engrenagens desmultiplicadoras para a secagem da esfregona por centrifugação e o seu método de funcionamento. Uma das suas vantagens é a possibilidade de acionar o mecanismo de rotação da esfregona (1) através do cabo (11) , estando este na sua totalidade no interior do balde (10), o que facilita a sua arrumação. Isto só é possível pela inovadora junção de um sistema de cremalheira (3) vertical, engrenagens cilíndricas e cónicas desmultiplicadoras e de um sistema de roquete (7), num só mecanismo. A desmultiplicação de cargas nas engrenagens reduz a carga necessária para se atingir a velocidade rotacional do cesto (2) necessária para a secagem da esfregona (1). Existe ainda uma redução dos custos de produção pela fácil e eficiente montagem do mecanismo, reduzindo o tempo e custo de mão-de-obra, assim como pelo tipo de componentes integrantes do mecanismo, sendo na sua maioria peças facilmente fabricadas por injeção plástica. Como representado nas Figuras de 1 a 8, este mecanismo inclui: balde (12), cesto (2), travão do cesto (13), base da esfregona (14), suporte da peça rotativa da esfregona (15), peça rotativa da esfregona (16), peça de encaixe do cabo (17), junção peça rotativa-peça de encaixe macho (18), junção peça rotativa-peça de encaixe fêmea (1.9), cremalheira (20), peça de guia da cremalheira (21), junção pinhão-roda cónica (22), junção carreto cónico-roda cilíndrica inferior (23), junção carreto cilíndrico inferior-roquete (24), um ou mais trincos (25), roda cilíndrica superior (26), junção carreto cilíndrico superior-veio dentado (27), tampa de suporte do mecanismo (28), base do mecanismo (9), peça de suporte do pinhão (29), peça de suporte da engrenagem cónica (30), peça de suporte do sistema de roquete (31) , peça de suporte do carreto cilíndrico superior (32), veio do pinhão (33), veio do carreto cónico (34), veio do roquete (35), parafusos (36), rebite (37), esfera (38), rolamento de esferas (39), rolamento de agulhas (40) e mola de compressão. O travão do cesto (13) é montado por encaixes ou por parafusos (36) no cesto (2) . The present invention, shown in Figures 1 to 8, relates to a gear reducer mechanism for drying the mop by centrifugation and its method of operation. One of its advantages is the possibility of activating the rotation mechanism of the mop (1) through the cable (11), which is in its entirety inside the pail (10), which facilitates its storage. This is only possible by the innovative coupling of a vertical rack system (3), cylindrical and bevelling gears and a ratchet system (7), in a single mechanism.

O método de funcionamento do mecanismo compreende as seguintes etapas: é exercido um movimento descendente no cabo (11) que consequentemente aciona a base da esfregona (14) contra o cesto (2) . O contacto entre a esfregona (1) e o cesto (2) acontece entre o encaixe da base da esfregona (50) e o encaixe do cesto (51). A esfregona (1) tem livre rotação, de modo a acompanhar a rotação do cesto (2), sendo aplicada em simultâneo uma carga descendente no cabo (11). Entre a base da esfregona (14) e a peça rotativa da esfregona (16) deve haver um rolamento de esferas (39) para diminuir o atrito. O cesto (2) está centralizado com o orifício do balde (52), com a junção carreto cilíndrico s perior-veio dentado (27} e com o veio da cremaiheira (42). O movimento descendente do cesto (2) faz com que o veio incorporado no cesto (53) acione a cremaiheira (20) pelo contacto com o veio da cremaiheira (42). Entre o veio incorporado no cesto (53) e o veio da cremaiheira (42) existe uma esfera (38), de forma a diminuir o atrito no contacto. Entre a cremaiheira (20) e a base do mecanismo (9) deve também haver uma mola de compressão, de forma a auxiliar o recuo da cremaiheira (20) . A cremaiheira (20) está posicionada na vertical e é engrenada com o pinhão (41) . A junção pinhão-roda cónica (22) gira em torno do veio do pinhão (33) e assim é acionado o engrenamento da roda cónica (43) com o carreto cónico (44) . A relação entre a roda e o carreto resulta na desraultiplicação do engrenamento. Na engrenagem cónica (4) é alterado o movimento de rotação do eixo horizontal para vertical. A junção carreto cóníco-roda cilíndrica inferior (23) gira em torno do veio do carreto cónico (34), acionando assim o engrenamento entre a roda cilíndrica inferior (45) e o carreto cilíndrico inferior {46} . Na ligação entre a engrenagem cilíndrica inferior (5) e a engrenagem cilíndrica superior (6) está incorporado o sistema de roquete (7), que limita a engrenagem cilíndrica superior (6) a uma rotação unidírecional , pelo engrenamento de um ou mais trincos (25) no círculo com dentado interior (49) coaxial e cavado na roda cilíndrica superior (26) . A junção carreto cilíndrico inferior-roquete (24) e a roda cilíndrica superior (26) giram em torno do veio do roquete (35) e, quando ativado o sistema de roquete (7), a partir do engrenamento dos trincos (25) no círculo com dentado interior (49), é acionado o engrenamento entre a roda cilíndrica superior (26) e o carreto cilíndrico superior (47) . A junção carreto cilíndrico superior-veio dentado (27) está diretamente ligada ao cesto (2), fechando o mecanismo. Esta ligação é feita através do engrenamento do veio dentado (8) com o cesto (2) restringindo-o a um movimento translacional vertical, provocando a sua rotação em simultâneo e a rotação da base da esfregona (14) . A junção carreto cilíndrico superior-veio dentado (27) é mantida no eixo vertical com o auxílio da peça de suporte do carreto cilíndrico superior (32) e da tampa de suporte do mecanismo (28). A tampa de suporte do mecanismo (28) é fixada à base do mecanismo (9) por encaixes ou por parafusos (36) . A peça de suporte do carreto cilíndrico superior (32) também é fixada à tampa de suporte do mecanismo (28) por encaixe ou por parafusos (36) . No interior da peça de suporte do carreto cilíndrico superior (32) deve ser acrescentado o rolamento de agulhas (40), de modo a diminuir o atrito na rotação entre a junção carreto cilíndrico superior-veio dentado (27) e a peça de suporte do carreto cilíndrico superior (32) . A peça de suporte do carreto cilíndrico superior (32) é separada da tampa de suporte do mecanismo (28) para facilitar o seu fabrico por injeção plástica. A peça de suporte do pinhão (29) e a peça de suporte da engrenagem cónica (30) auxiliam a montagem do veio do pinhão (33), facilitando também o fabrico da base do mecanismo (9) por injeção plástica. A peça de suporte da engrenagem cónica (30) suporta o veio do carreto cónico (34) . A peça de suporte do sistema de roquete (31) é separada da base do mecanismo (9) para facilitar o seu fabrico por injeção plástica. A tampa de suporte do mecanismo (28) constringe a nulo o movimento da peça de suporte do pinhão (29) , da peça de suporte do sistema de roquete (31), do veio do carreto cónico (34) e do veio do roquete (35) . A peça de suporte do sistema de roquete (31) suporta o veio do roquete (35) . Todo o mecanismo de rotação é compactado no interior do balde (10) . A complexa desmultiplicação das engrenagens é necessária para que o cesto (2) gire o suficiente para realizar a secagem dos filamentos da esfregona, com poucos movimentos descendentes da esfregona e com uma baixa carga de atuação para os efetuar . The method of operation of the mechanism comprises the following steps: a downward movement is exerted on the handle (11) which consequently drives the base of the mop (14) against the basket (2). The contact between the mop (1) and the basket (2) takes place between the mop base engagement (50) and the basket engagement (51). The mop 1 has free rotation so as to follow the rotation of the basket 2, while a downward load on the cable 11 is applied simultaneously. Between the base of the mop (14) and the rotating part of the mop (16) there must be a ball bearing (39) to reduce friction. The basket 2 is centralized with the bore of the bucket 52, with the cylindrical sprocket-to-nozzle 27 joint and with the creamer shaft 42. The downward movement of the basket 2 causes the shaft incorporated in the basket 53 drives the crèche 20 by contact with the crusher shaft 42. Between the shaft incorporated in the basket 53 and the crusher shaft 42 is a ball 38, (20) and the base of the mechanism (9) there should also be a compression spring, so as to assist the indentation of the creamer 20. The creamer (20) is positioned in the groove vertical and is meshed with the pinion 41. The conical pinion wheel joint 22 rotates about the pinion shaft 33 and thus the engagement of the bevel gear 43 with the conical gear 44 is driven. The relationship between the wheel and the carriage results in the de-articulation of the gear unit. In the conical gear (4) the rotation movement of the horizontal axis is changed to vertical. The lower cylindrical conical-wheel gear assembly 23 rotates about the shaft of the conical gear 34, thereby driving the engagement between the lower cylindrical wheel 45 and the lower cylindrical gear 46. In the connection between the lower cylindrical gear 5 and the upper cylindrical gear 6, the ratchet system 7, which limits the upper cylindrical gear 6 to a unidirectional rotation, is engaged by the engagement of one or more latches 25) in the inner toothed ring (49) coaxially and dug in the upper cylindrical wheel (26). The lower cylindrical ratchet gear 24 and the upper cylindrical wheel 26 rotate about the ratchet shaft 35 and, when the ratchet system 7 is activated, from the engagement of the latches 25 in the (49), the engagement between the upper cylindrical wheel (26) and the upper cylindrical gear (47) is actuated. The upper cylindrical gear-toothed gear coupling 27 is directly attached to the basket 2, closing the mechanism. This connection is made by engaging the toothed shaft 8 with the basket 2 restricting it to a translational vertical movement, causing it to rotate simultaneously and rotation of the base of the mop 14. The upper cylindrical gear-toothed gear coupling 27 is maintained on the vertical axis with the aid of the upper cylindrical gear support part 32 and the mechanism support cover 28. The support cover of the mechanism 28 is secured to the base of the mechanism 9 by recesses or screws 36. The support part of the upper cylindrical carriage 32 is also secured to the mechanism support cover 28 by engagement or by screws 36. Inside the upper cylindrical pinion support part (32) the needle bearing (40) must be added so as to reduce the friction in the rotation between the upper cylindrical gear-toothed gear coupling (27) and the upper cylindrical gear support member (32). The upper cylindrical sprocket support member 32 is separated from the support cover of the mechanism 28 to facilitate its manufacture by plastic injection. The pinion support part 29 and the conical gear support part 30 assist in the assembly of the pinion shaft 33, also facilitating the manufacture of the base of the mechanism 9 by plastic injection. The conical gear support part (30) supports the shaft of the conical gear (34). The support part of the ratchet system (31) is separated from the base of the mechanism (9) to facilitate its manufacture by plastic injection. The support cover of the mechanism 28 constrains the movement of the pinion support member 29, the ratchet support member 31, the conical gear shaft 34, and the ratchet shaft to zero. 35). The support part of the ratchet system (31) supports the ratchet shaft (35). The entire rotating mechanism is compacted within the bucket (10). The complex gearing of the gears is necessary so that the basket (2) rotates enough to dry the mop filaments, with few downward movements of the mop and with a low actuation load to effect them.
