Description

Bathroom heater switch with switching device

Technical Field

The invention relates to the field of switches, in particular to a bathroom heater switch with a switching device.

Background

The bathroom heater is an electrical appliance commonly used in our home life. Especially in recent years, the air heating bath warmer is not dazzling like light heating, does not have explosion danger like lamp heating, has more sufficient hot air, enables the bath and warming of the bathroom to be more convenient and safer, and is widely popular with consumers.

The common bathroom heater is characterized in that two motors work and drive respectively for blowing and ventilating, but a single-motor air-heating bathroom heater is provided, namely, the motor is used for blowing and ventilating, the motor is arranged above a heating tube (wire), the motor realizes two functions of blowing and ventilating through positive rotation and reverse rotation, the heat of the heating tube (wire) can be blown down by positive rotation blowing for heating, and the air polluted by indoor moisture can be exchanged with outdoor air by reverse rotation ventilating. The single-motor bath heater only uses one motor, so the structure is simpler and more durable than that of a double-motor bath heater, and the cost is lower.

However, the single-motor bath heater also has some problems, and the switch corresponding to the single-motor bath heater is relatively complex in design and is more troublesome to use than the double-motor bath heater switch. Because the blower and the ventilation share one motor, the blower and the ventilation function cannot be arranged on two keys on a common switch, otherwise, the two keys are easy to press simultaneously, and the shared motor cannot work or even burn.

In order to solve the problem, the current solution is to arrange the air blowing and the air exchange on the same switch key, so that the air blowing or the air exchange is respectively carried out when the switch is pressed down, and the misoperation can never occur. The solution is to solve the problem that the single motor bath heater can not operate by mistake when the blower and the ventilation positive and negative rotation motor rotate, but a power switch key must be additionally arranged, otherwise, one of the blower and the ventilation always works. When the air blowing and ventilating switch is used, the power key must be pressed firstly, the motor key is electrified, one function is started firstly, then the motor key is pressed to switch air blowing and air exchanging from top to bottom, the use is complicated, and the consumer experience is not good.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 shows a bathroom heater switch with a switching device of the present invention, which comprises a ventilation button 1, a blowing button 2 and a button support 3, wherein the ventilation button 1 and the blowing button 2 are arranged on the button support 3; as shown in fig. 2, the device further includes a switching device 4, the switching device 4 is disposed on the key holder 3, and the ventilation key 1 and the blower key 2 cannot be closed at the same time by the switching device 4.

As shown in fig. 3-4, a positioning clip 5 is disposed on the key holder 3, the switching device 4 is fixed on the key holder 3 via the positioning clip 5, and the switching device 4 is a spring leaf, preferably, the spring leaf is V-shaped; one end of the spring piece is arranged at the inner side of the ventilation key 1, and the other end is arranged at the inner side of the blowing key 2. When the ventilation key 1 is pressed down, one end of the switching device 4 is pressed down, and meanwhile, the other end of the spring piece can be tilted up to drive the blowing key to be disconnected due to the lever principle; the same principle, when pressing the button of blowing, make the button of taking a breath disconnection through the spring leaf transmission.

The on and off positions of the switch can be changed only by changing the wiring mode of the electric wire, so the installation position of the switching device 4 is not limited, one end of the switching device 4 is arranged at the inner side of the ventilation key 1, the other end of the switching device 4 can be arranged at the inner side of the same end of the blowing key 2 relative to the ventilation key 1, and of course, the other end of the switching device can also be arranged at the inner side of the opposite end of the blowing key 2 relative to the ventilation key 1.

In order to make the relative movement of the end part of the switching device 4 smoother when the ventilation key 1 or the blowing key 2 is pressed down, arc-shaped structures are arranged at two ends of the switching device 4, and because the contact surfaces of the arc-shaped structures and the keys are always smooth, phenomena such as blocking, unsmooth switching and the like cannot occur.

The switching device 4 is fixed on the key support 3 through the positioning card 5, the switching device 4 can clamp the convex shaft 6 in the positioning card 5 by arranging the convex shaft 6, the movable connection between the switching device 4 and the positioning card 5 is realized, and the switching device can swing by taking the convex shaft 6 as a center.

As shown in fig. 5-7, the switching device 4 is disposed on the same side of the ventilation button 1 and the blowing button 2, when in use, the buttons are in the state shown in fig. 5, and when the ventilation button 1 needs to be pressed, the ventilation button 1 only needs to be pressed, and the state shown in fig. 6 is reached. At this time, if the blowing button 2 needs to be opened, one end of the switching device 4 is pressed down and the other end is lifted up while the blowing button 2 is pressed down, so that the ventilation button 1 is lifted up, namely, is disconnected, as shown in fig. 7. When both functions are required to be closed, the other end of the opened key is pressed to close the two functions.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, for example, the positioning clip 5 for fixing the switching device 3 may be configured as a link shaft type clip slot; it is intended that the following claims be interpreted as including all such alterations, modifications, and equivalents as fall within the true spirit and scope of the invention.
