Description

Ceiling fan switch housing

The invention relates to a ceiling fan switch housing.

The form of one known ceiling fan assembly is shown among Fig. 1 to Fig. 3 of accompanying drawing.

It comprises a motor case 1, this motor case hangs under ceiling and has among the flabellum 2(figure and only illustrates one), one comprises the switching device 3 that is used to control motor operated switching mechanism, as the lighting apparatus 4 of a ceiling fan assembly part, because such ceiling fan assembly normally is contained in the place of lighting apparatus.

In detail referring to Fig. 2 and Fig. 3, switch comprises upper case part 30, its becomes put upside down a glass figure and comprise switching mechanism 32, having some electrical wires 33 to pass hollow shaft sleeve 35 from switching mechanism 32 upwards stretches, with connection motor and power supply, and this hollow shaft sleeve 35 is positioned at the center of top of whole casing body 30.The bottom 31 of switching device 3 removably is fixed in the bottom of upper case body 30 with at least one fixed screw 41, need receive device 3 or can contact the inside of device when installing 3 separation when needing to repair with convenient switching mechanism 32 or when lighting apparatus.Being electrically connected between motor case 1 and the switch 3 more permanently fixed during fabrication by the producer.Install then together with motor case and the switching device that fixed and be supplied to retailer or user.Because being electrically connected between them so just is not easy to separate.

Above device has some shortcomings.At first, suppose device as shown in Figure 1, be installed on the ceiling, in the time need overhauling the inside of switch-box, must remove bottom 31 could carry out work to its inside, and vertical like this its inside of looking up is hard especially and inconvenient; Perhaps, also can move whole device (remember motor case and switching device are not be designed to can be segregative) from ceiling, clearly be inconvenient but do like this.

Second shortcoming is exactly, if desired lighting device is received on the device that is fixed on the ceiling or from being fixed on the device on the ceiling lighting apparatus is removed following time, just must do together with the switching device that still is fixed in motor case, the result, the people who does this work has run into above-described connection and the problem of separating relevant electrical wire again, and also wants him to support the weight of lighting apparatus simultaneously.This means, may need another person to help him to carry out this work.When in addition, lighting device being installed must when setter is careless, safety problem can take place to dump.

The 3rd, because motor case and switching device comparatively permanently are connected to each other them together by the producer, and a certain stage on the such assembly line of switching device in its manufacture process just can not handle individually, and in fact individual processing is comparatively ideal.In addition,, wasted packing and storage area, can greatly increase the ultimate cost of product like this because the global shape of motor case that has assembled and switching device is very big.

All these problems for many years make the people who makes ceiling fan feel headache, and basic goal of the present invention are will overcome these shortcomings or alleviate these shortcomings at least always.

According to the present invention, one ceiling fan switch housing is arranged, comprise by one can be fixed in motor case and have or be connected with comprise first wire element with the upper case part and that connects said motor and power supply hold motor switch mechanism and easily by the user being connected to said upper case partly or the lower case part of partly removing from said upper case, said lower case partly has second wire element, so that said switching mechanism is connected to motor and power supply, said second wire element can easily be connected to said first wire element or be removed following from said first wire element by the user.

Can overcome or lower at least whole shortcomings of above-mentioned existing apparatus according to switching device of the present invention.

The first, hold the lower case part of switching mechanism and can easily partly remove from upper case.For example, at first unclamp a fixed screw and easily separate the said first and second lead original papers then, so that can handle the switching mechanism that is in the lower case part on the ground, for example on a table top.The second, for the lower case part after such separation, the user can be easy to connect a last lighting apparatus or take off a lighting apparatus above it.The 3rd, because the user can be connected to each other the upper and lower housing parts of switch and separate simply, comprise switching mechanism lower case part can by the producer after a while in before fabrication stage carry out individual processing, then together with but the motor case and the upper case part of having separated be packaged in abreast in the rectangular cardboard box, lower case is partly placed the corner of cardboard box, otherwise, this corner has been the space that slatterns, thereby lowered the necessary height of cardboard box, so that save storage area and freight.

The 4th, owing to itself be the use of the separate type socket that encases of insulated body, setter and power supply are isolated fully, have reduced Danger Electric shock risk.The 5th, because this switching device can be handled separately, improve the production work efficiency, work employee simultaneously can increase by 30% output in the same time.

More preferably, said first and second wire elements are terminated at corresponding single electrical cnnector, and the preferred shape of plug and socket is respectively and is easy to connect and separate.

Embodiments of the invention will and be narrated with reference to the accompanying drawings by example.

These accompanying drawings are:

Fig. 1 is the side view of traditional ceiling fan of narrating;

Fig. 2 is the side view of the switching device of device shown in Figure 1;

Fig. 3 demonstrates the released state of the switching device upper and lower housing parts of Fig. 2, and the scarce part of going is to show its inside;

Fig. 4 is the side view of switching device lower case of the present invention;

Fig. 5 is similar in appearance to Fig. 3, but is switching device of the present invention, and its underpart housing parts then is shown in Fig. 4.

The prior art ceiling fan of Fig. 1 to Fig. 3 was narrated in the above, so will no longer narrate.

Referring now to Figure 4 and 5, be depicted as switching device of the present invention, it comprises upper and

lower housing parts

50 and 51, they are with the same manner of as shown in Figure 1 to Figure 3 device, can be connected with lighting apparatus 4 with motor case 1, by using a fixed screw 41 to connect upper cases part and motor cases, or with other traditional connection means (not shown) connection lower case part 51 and lighting apparatus.The method that the switching mechanism 53 of switching device is connected to motor and power supply is then fully different, and this will narrate below.

Switching mechanism 53 is installed in the lower case 51, and lower case part 51 is made cup-shaped basically, and is used for switching mechanism is connected to motor and all terminates in a single plug 55 to the wire element 56 of power supply.50 shapes of making the lid of cup-shaped lower case part 51 of upper case part, wire element 57 connects motor and power supply and is terminated at single electrical socket 54 by hollow shaft housing 58.Plug 55 and socket 54 are just as upper and

lower housing parts

50 and 51 easy connections and separation, and the advantage that has the front to narrate.

Lower case part 51 has a ring that is made of the radial drawing deep trouth 52 that stretches, deep trouth has ventilation gaps 59 in its radiation direction, make air by switching device flow to the top and by the roof of upper case part 50 another ring (not shown) with aperture flow out.Because the top surface of upper case part 50 is never for the user sees, need not applies plating to it; And can varnish with lacquer simply to prevent corrosion, this is certainly than electroplating considerably cheaper.
