[0029] The transparent touch switch 3 includes a transparent touch panel 100 provided with button identifiers. The transparent touch panel 100 is provided with a light source on the side close to the smoke collecting hood 1, which is used to irradiate the emitted light to the button identifiers so that the button identifiers are displayed on the transparent touch panel 100. The range hood with the transparent touch switch 3 of the present utility model includes a smoke collecting hood 1 and a smoke baffle 2. A transparent touch switch 3 is provided on the side of the smoke collecting hood 1 facing the smoke baffle 2. The transparent touch switch 3 includes a transparent touch panel 100 provided with button identifiers. The transparent touch panel 100 is provided with a light source on the side close to the smoke collecting hood 1. The light source is used to provide a display light beam, and at least part of the display light beam is used to be transmitted to at least one button identifier in at least part of the area where the transparent touch panel is located. By adopting the above range hood with the transparent touch switch 3, not only the problem that when the touch switch is in the off state, a black display window appears on the front panel of the white range hood, thereby reducing its aesthetic performance, but also the atmosphere of the white range hood is greatly enhanced.

[0030] Specifically, the range hood further includes a front panel 4.

[0031] In some embodiments, the transparent touch panel 100 includes a touch layer 101, which is used to sense the button pressing action of the user's finger and generate an electrical signal. The touch layer 101 is arranged on the transparent touch panel 100.

[0033] In some embodiments, the touch layer 101 is a transparent conductive film. Setting the touch layer 101 as a transparent conductive film can increase the sensing area, thereby increasing the touchable area of the user, improving the sensitivity of the touch switch. At the same time, the transparent touch panel 100 composed of the transparent conductive film is integrally transparent, which not only does not affect the overall appearance of the white range hood, but also can improve the atmosphere of the whole machine and enhance the user's experience.

[0034] Specifically, the touch layer 101 is an indium tin oxide film.

[0035] In some embodiments, the transparent touch switch 3 further includes a control circuit board 300, which is electrically connected to the light source and the transparent touch panel 100. Connecting the control circuit board 300 electrically to the light source and the transparent touch panel 100 enables the control circuit board 300 to control the lighting and extinguishing of the corresponding button identifiers on the transparent touch panel 100 according to the received electrical signals.

[0036] Specifically, the control circuit board 300 is electrically connected to the range hood. When the user makes a button operation, the control circuit board 300 causes the corresponding button identifier on the transparent touch panel 100 to light up according to the received electrical signal. At the same time, the control circuit board 300 issues a corresponding instruction to the range hood, and the range hood generates a corresponding action for the instruction; the lighting of the corresponding button identifier can prompt the user that the range hood is in the operating state corresponding to the lit button identifier.

[0037] Specifically, the light source is an LED lamp.

[0039] In some embodiments, the transparent touch panel 100 further includes a first transparent film 102 and a second transparent film 103. A first optical adhesive layer is sandwiched between the first transparent film layer 102 and the touch layer 101, and a second optical adhesive layer is sandwiched between the second transparent film layer 103 and the touch layer 101. The first transparent film 102, the second transparent film 103, the first optical adhesive layer, and the second optical adhesive layer in the transparent touch panel 100 are all light-transmissive, making the overall transparent touch panel 100 appear transparent, avoiding the problem that when the touch switch is turned off, a black display window appears on the front panel of the white range hood, thereby reducing its aesthetic performance.

[0040] Specifically, both the first optical adhesive layer and the second optical adhesive layer are formed by curing OCA optical adhesive. The first transparent film layer 102 is bonded to the touch layer 101 through OCA optical adhesive, and the second transparent film layer 103 and the touch layer 101 are bonded through OCA optical adhesive.

[0041] Specifically, the first transparent film 102 includes at least one of a PC film, a PET film, a PP film, and a PVC film, and the second transparent film 103 includes at least one of a PC film, a PET film, a PP film, and a PVC film.

[0042] Specifically, both the first transparent film 102 and the second transparent film 103 are PC films.

[0043] In some embodiments, the transparent touch switch 3 includes a support assembly 200. An installation opening is provided on the smoke collecting hood 1 of the range hood. The support assembly 200 is embedded in the installation opening and fixedly connected to the smoke collecting hood 1.

An outwardly protruding installation groove is provided on the fixed seat 201, and one end of the transparent touch panel 100 is snap-fitted into the installation groove. The snap-fitting of the transparent touch panel 100 and the installation groove makes the disassembly of the transparent touch panel 100 and the support assembly convenient and facilitates installation.

[0046] Specifically, a first through hole for accommodating a fastener is provided on the side wall of one side of the installation groove, and a first blind hole is provided on the side wall of the other side. A second through hole is provided at one end of the transparent touch panel 100 close to the installation groove. The fastener passes through the first through hole and the second through hole and then extends into the first blind hole, and the fixed seat 200 and the transparent touch panel 100 are detachably connected by the fastener.

[0047] Specifically, the fastener can be a mechanical element such as a bolt, a screw, a stud, etc. for connection and fixation.

[0048] In some embodiments, the support assembly 200 includes a rear cover 202. A receiving groove is recessed in the rear cover 202, and the receiving groove is used for installing the control circuit board 300. The control circuit board 300 is installed on the rear cover 202. At this time, the distance between the control circuit board 300 and the transparent touch panel 100 is short, and the control circuit board 300 can better receive the electrical signal transmitted from the touch layer in the transparent touch panel 100, making the transparent touch switch 3 more sensitive.

[0049] In some embodiments, the support assembly 200 further includes a connecting member. An installation hole for accommodating the connecting member is provided in the receiving groove of the rear cover 202, and a first through hole corresponding to the position of the installation hole is provided on the fixed seat 201.

Fixing the rear cover 202 and the fixed seat 201 can improve the stability of the support assembly 200, and further improve the stability of the transparent touch switch 3.

[0050] Specifically, a third through hole corresponding to the position of the installation hole is provided on the control circuit board 300. The connecting member passes through the first through hole, the second through hole and the third through hole in sequence and then extends into the installation hole to connect the rear cover 202, the control circuit board 300 and the fixed seat 201.

[0051] Specifically, the connecting member can be a mechanical element such as a bolt, a screw, a stud, etc. for connection and fixation.

[0052] In some embodiments, a limiting portion protrudes from an end surface of the mounting hole at one end facing away from the rear cover 202, and a positioning portion is provided on the end surface at the other end. A third through hole provided on the control circuit board 300 passes through the limiting portion and then contacts an end surface of one end of the positioning portion of the mounting hole, so as to limit the relative position between the control circuit board 300 and the rear cover 202.

[0053] Specifically, the mounting hole is cylindrical.

[0054] In some embodiments, the transparent touch switch 3 further includes a sealing member 400, and the sealing member 400 is sleeved on the support assembly 200. The sealing member 400 is provided on the transparent touch switch 3 to protect the transparent touch switch 3 from oil pollution, which not only improves the safety performance of the transparent touch switch 3, but also improves the service life of the transparent touch switch 3.
