Problems solved by technology

[0004] Based on this, it is necessary to solve the problem that the oil-stained hand of the user touches the on-off of the range hood to solve the problem that the remote control of the range hood touch switch cannot be realized sensitively and conveniently in the prior art, and to provide a It can control the on-off of the touch switch from a distance, which can avoid the range hood with low touch sensitivity when the user directly controls the on-off of the touch switch with greasy hands

Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom", "top" and similar expressions...

Abstract

The invention relates to an extractor hood. The extractor hood comprises a shell, a touch control switch and an indication panel. The touch control switch and the indication panel are oppositely arranged and are located on the two sides of the shell correspondingly. The touch control switch comprises a key circuit board, a plurality of trigger pieces arranged on the key circuit board, and a plurality of conductive execution pieces corresponding to the trigger pieces in a one-to-one manner. The key circuit board is provided with a touch induction circuit. The trigger pieces sense the control actions on the indication panel side and output corresponding manipulation signals. The touch induction circuit correspondingly receives different manipulation signals and output different control signals. The conductive execution pieces receive the different control signals and execute the corresponding control actions. The extractor hood can achieve the isolated-space touch control switch on-off state control, and the touch control sensitivity is high.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a range hood. Background technique [0002] In the prior art, touch switches of many electronic products are realized by the principle of capacitive sensing. Specifically, a thin plate of non-metallic material is arranged in front of the touch switch, and the thin plate is generally made of materials such as glass, plastic and acrylic. Touch the corresponding position on the non-metal thin plate with human fingers to realize the on-off control of the touch switch. [0003] Among them, the touch switch of the range hood is also designed using the principle of capacitive sensing, that is, the on-off control can be realized by directly touching the corresponding position of the touch switch with a finger. However, during the cooking process, the user's hands are often sticky with oil or water, making it inconvenient to touch. In order to overcome this defect, a gesture c...
