[0002] In dental medical equipment, since most dentists need to hold mobile phones with different functions with both hands, if they need to control the water and gas volume of the dental chair or the mobile phone, they often need to use a foot control device to handle it.

[0003] Most existing foot control devices include a foot mounting box, on which a movable pedal for operation control is mounted, and a plurality of push-type movable buttons are arranged on the surface of the foot mounting box. Dentists can adjust and control the dental chair or dental mobile phone by stepping on the corresponding movable pedal or movable button with their feet.

[0004] When the movable pedal is stepped on, the existing foot control device contacts the air valve in the foot mounting box through the movable pedal to achieve adjustment control. However, in the prior art, the movable pedal directly contacts the air valve, which easily causes the precision seal on the air valve to be misaligned, thereby greatly reducing the service life of the foot control device, so improvement is needed.

[0021] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
