Description
Vynález sa týká rotujúcej kefy, u ktorej sa rieší usporiadanie jej ochranného krytu,The present invention relates to a rotating brush in which its protective cover is provided,
Sú známe rflzne vyhotovenie rotujúoioh kief, pričom, akaú vybavené ochranným krytom, tento alúži ako bezpečnostný prvok zabraňujúci xnežiaducemu styku a vlaemi kefy, resp. sa využívá ako čaať zariadenia na odstraňovenie činnoaťou kefy vznikajúcich produktov, napr. odsáváním, pre přívod čistiaceho média a podobna. V případe kefy a radiálně amerujúcimi vlaami zakrýva ochranný kryt celý obvod kefy okrem činnéj časti a jeho priemer je vfičší než priemer opisovaný koncaml vlaaov. Vzhladom k rozmarom napr. čiatenej plochy je takto uaporiadaná kefa nevýhodné velká a nemožno ju použiť v menej přístupných miestach.Various embodiments are known for rotating brushes, which, provided with a protective cover, serve as a safety feature to prevent undesired contact with the brushes or the brushes. is used as a teat stripping device for emerging products, e.g. suction, for supply of cleaning medium and the like. In the case of a brush and radially extending trains, the protective cover covers the entire circumference of the brush except the active part, and its diameter is larger than the diameter described by the ends of the trains. Due to the whims of e.g. the brushed surface is thus disadvantageously large and cannot be used in less accessible places.
Vyššia uvedené nedostatky aú odstránené ochranným krytom rotujúcej kefy podlá vynálezu, ktorého podstatou je, že ochranný kryt, ktorý zakrýva celý obvod kefy okrem Činnéj-časti, pričom velkost Činnéj časti je možné menlť, je usporiadaný na priemere menšom než je priemer rotujúcej kefy bez krytu.The aforementioned drawbacks have been eliminated by the rotating brush guard according to the invention, which consists in that the guard covering the entire circumference of the brush except the active part, the active part size being smaller, is arranged on a diameter smaller than the diameter of the rotating brush without the cover. .
Vytvořením takto usporiadaného krytu sa docieli zmenšenie celkových rozmerov kefy, zmenšenie rozmerov a hmotnosti krytu, výhodný poměr medzi rozmerml napr. čiatenej plochy a T*o?«?rml vlastněj kefy, zlepší aa použitie kefy v menej přístupných miestach a je možné dosiahnuť aamočistieci účinok vlaaov kefy.By designing the cover so arranged, the overall dimensions of the brush, the dimensions and the weight of the cover are reduced, the preferred ratio between the dimensions of e.g. the brushed area and the T * o? rml of the actual brush, will improve the use of the brush in less accessible areas, and it is possible to achieve the cleansing effect of the brushes.
Na pripojenom výkrese sú znázorněné dva příklady vyhotovenia rotujúcej kefy podlá vynálezu, kde na obr. 1 je znázorněná čistiaca kefa s nastavitelnou činnou časťou a na obr. 2 rotujúca kefa a pevným krytom v činnosti.In the accompanying drawing, two exemplary embodiments of a rotating brush according to the invention are shown. 1 shows a cleaning brush with an adjustable working part, and FIG. 2 a rotating brush and a fixed cover in operation.
Okolo rotoru 1 / obr. 1 / neaúcaho vlasy 2 je umiestnaný kryt 3 a jeho pohyblivá čaať 4 tak, Že ich vzájomná poloha sa dá meniť v určitom rozsahu natáČaním pohyblivej časti £ krytu 2 okolo oai rotora 1. Kryt 3 je uložený na poloměre menšom než je poloměr obrysu 8 volnaj kefy. Vzájomná poloha Jerytu 3 a pohyblivej časti 4 vytvára medzi náběžnou hranou g a úbežnou hranou 6 rdzne velký činný profil % vytvořený vlaami 2. V případe použitia iba neděleného kry tu 3 / obr. 2 / sa činný profil vytvára polohou nábežnej hrany § a úbežnej hrany 6. Nábežná hrana 5 alúži pri rotácli kefy podía vyznačenéj šipky na usmernenie vlaaov 2 pod kryt 2» respektive i ne člatenie vlaaov 2 a úbežná hrana 6 na vypúšťanie vlaaov 2 spod krytu 3, respektive i na nanášanie inej, látky na vlasy 2. Ich funkcia sa mdže navzájom meniť změnou zmysluAround the rotor 1 / fig. 1 / not wearing hair 2, the cover 3 and its movable wait 4 are positioned so that their relative position can be changed to a certain extent by pivoting the movable part 6 of the cover 2 around the rotor 1 and 1. The cover 3 is mounted on a radius smaller than the radius 8 brush. The relative position of the Jeryt 3 and the movable portion 4 forms a differently large active profile formed by the waveguides 2 between the leading edge g and the leading edge 6. 2 / the active profile is formed by the position of the leading edge 6 and the leading edge 6. The leading edge 5 is also used when the brush is rotated according to the arrow to guide the trains 2 under cover 2 ». or for the application of another hair cloth 2. Their function can change with each other by changing the sense

Výhodná jo aplikácia pre elektricky poháftanú rotujúcu zubnú kefku, pretože použitím rotujúcej kefy podlá vynálezu sa dosiahne přesná ohraničenle čistenej plochy zubu pri výhodě malých rozmerov a správného Slstiaceho pohybu vlasov kefy. Použitie vynálezu je výhodná aj v priemysle pri Sletění ohraničených pldoh najmě s využitím pohyblivej časti krytu, napr· ako přídavné zariadenie k pneumatickým, Si elektrickým ručným bráškem, vrtačkám a podobna· Kryt vyhotovený podl*a vynálezu je možné použit aj u iných než rotačných kief.The preferred application is for an electrically powered rotating toothbrush, since the use of the rotating brush according to the invention achieves an accurately bounded brushed tooth surface, with the advantage of small dimensions and proper fusing brush hair movement. The use of the invention is also advantageous in the industry for splicing limited enclosures using, in particular, a movable part of the housing, e.g. as an add-on to pneumatic, Si electric handbrakes, drills and the like. .
