Description

Technical Field

[0001] The present invention relates to the technical field of hand dryers, and more specifically, to an anti-theft hand dryer. Background Art

[0002] A hand dryer is a sanitary ware electrical appliance used to dry hands in a bathroom, which is divided into an induction automatic hand dryer and a manual hand dryer. It is mainly used in places such as hotels, restaurants, research institutions, hospitals, public entertainment venues, and bathrooms in each family. Due to the large number of people and miscellaneous eyes in public places, the hand dryer directly hung and installed at the bathroom door is easily removed and stolen by miscreants. If a lock is set on the hand dryer, a key is required to disassemble it during disassembly and maintenance. If the key is not brought, it cannot be disassembled, which is very troublesome. Summary of the Invention

[0003] In summary, in order to overcome the deficiencies of the prior art, the present invention provides an anti-theft hand dryer that is simple to install, can prevent theft, and does not require a key for disassembly.

[0004] To achieve the above object, the present invention provides the following technical solution: An anti-theft hand dryer includes a hand dryer assembly. The hand dryer assembly is provided with a rear cover, and further includes an installation device. The installation device includes a main frame, a cover plate, a clamping table, and a first reset member. The main frame is provided with a plurality of table grooves. One side of the clamping table facing the hand dryer is provided with a guiding inclined surface. The clamping table is provided with a sliding table adapted to the table grooves. A baffle for preventing the clamping table from sliding out is provided at the outlet of the table grooves. The first reset member is located between the clamping table and the table grooves. The rear cover is provided with a connection groove adapted to the installation device. A clamping groove adapted to the clamping table is provided at a position corresponding to the table grooves in the connection groove. An opening and closing hole is provided on the outer wall of the rear cover at a position corresponding to the clamping groove. The opening and closing hole is provided with an opening and closing button. A connection hole penetrating through the clamping groove is provided at the bottom of the opening and closing hole. The clamping groove is provided with a pushing plate. The pushing plate includes a main pushing plate and a retaining table pushing plate. The pushing plate is provided with a connecting rod adapted to the connection hole. The opening and closing button is connected to the connecting rod. When the opening and closing button reaches the bottom of the opening and closing hole, the main pushing plate is located at the opening of the clamping groove. The thickness of the retaining table pushing plate is equal to the depth of the clamping groove.

[0005] Set up like this. When installing, align the connection slot on the hand dryer with the installation device on the wall and press it in. The side of the connection slot will press the clamping platform into the table slot along the guiding inclined surface of the clamping platform. When the clamping slot is pressed in, the first resetting member will be compressed. When the hand dryer is fully pressed in, the clamping slot will move to the position of the table slot. The unobstructed clamping platform will bounce out of the table slot under the action of the first resetting member and insert into the clamping slot until the sliding platform of the clamping sleeve is blocked by the baffle and cannot continue to bounce out. At the position of the clamping slot with the retaining platform push plate, the clamping platform will press against the retaining platform push plate. At this time, the hand dryer will be clamped by several clamping platforms inserted into the clamping slot and hung on the wall. Since there is no guiding inclined surface on the back of the clamping platform, the hand dryer cannot be directly removed, reducing the possibility of being stolen. When it is necessary to remove the hand dryer for maintenance, just press the opening and closing button at the position of the clamping slot without the retaining platform push plate and press it to the bottom of the opening and closing hole. The main push plate connected to the opening and closing button will just push the clamping platform in the clamping slot out of the clamping slot without entering the table slot. At this time, the hand dryer can be directly removed. People who don't know which buttons are set with the retaining platform push plate will press the retaining platform push plate. When the retaining platform push plate is pressed, the retaining platform push plate will be pressed into the table slot. At this time, although the clamping platform is pushed out of the clamping slot, the hand dryer will be stuck by the retaining platform push plate in the table slot and still cannot be removed. The disassembler only needs to know which opening and closing buttons to press to disassemble, without taking a key. Even if they forget, they can call someone who knows to find out the opening method.

[0006] Further, at least one step groove is provided on the side of the opening and closing button facing the connection hole. A positioning platform is provided at the bottom of the opening and closing hole. The height of the positioning platform is equal to the distance from the end face of the connection hole to the bottom of the step groove. The push plate further includes a secondary push plate. The thickness of the secondary push plate is greater than that of the main push plate. The thickness difference between the thickness of the secondary push plate and the thickness of the main push plate is equal to the depth of the step groove.

[0007] Set up like this. When the step groove rotates out of the position of the positioning platform, the opening and closing button will first contact the positioning platform when pressed, reducing the moving distance of the opening and closing button. At this time, the main push plate will not be able to push the clamping platform out of the clamping slot. Since the secondary push plate is thicker than the main push plate and the thickness difference is the same as the depth of the step groove, the secondary push plate will just push the clamping platform out of the clamping slot. When the step groove rotates to the position of the positioning platform, since the height of the positioning platform is equal to the distance from the end face of the connection hole to the bottom of the step groove, the positioning platform will not block the contact between the opening and closing button and the bottom of the opening and closing hole. In this way, the opening and closing button has a state with the number of step grooves plus one, and a disassembly password with several times greater difficulty can be set.

[0008] Further, the opening and closing button is provided with an indicating needle.

[0009] Set up like this. The position of the step groove can be judged through the indicating needle, without continuous trial, simplifying the operation.

[0010] Further, a chamfer is provided on the side of the push plate facing the hand dryer assembly.

[0011] With such arrangement, when a portion of the main push plate enters the table groove due to processing error or when the opening and closing button rotates and changes the movable distance when the connecting column rod and the opening and closing button are threadedly connected, the hand dryer can still be removed along the chamfer.

[0012] Furthermore, a second restoring member is provided between the opening and closing button and the opening and closing hole.

[0013] With such arrangement, when the hand dryer is removed, the second reset member will push the on / off buttons at all positions to the same position, making it impossible for others to judge which positions are provided with the main push plate, which positions are provided with the auxiliary push plate, and which positions are provided with the retaining platform push plate from the degree of depression of the on / off buttons.

[0014] Furthermore, the opening and closing button is provided with a reset groove, and the diameter of the reset groove is clearance-matched with the outer diameter of the second reset member.

[0015] With such arrangement, the second reset member, such as a compression spring or other parts, can support the entire end surface of the opening and closing button in the reset groove instead of being more stable because the step groove only contacts a part of the end surface.

[0016] Furthermore, the side wall of the opening and closing button is provided with auxiliary grip teeth.

[0017] With this arrangement, when the opening and closing button is rotated, the hand contacts the auxiliary grip teeth, which increases friction and makes it easier to turn.

[0018] Furthermore, the main frame is provided with an alarm module, the switch of the alarm module is located at the bottom of the table groove, and a pressing column is provided on the side of the card table facing the switch of the alarm module, and when the opening and closing button is located at the bottom of the opening and closing hole, the pressing column contacts the switch of the alarm module.

[0019] With such arrangement, if an unscrupulous person wants to steal, he will press the opening and closing button with the platform blocking push plate, and then the platform blocking push plate will push the card table into the deep of the table slot. When the push plate of the opening and closing button is pressed to the bottom, the pressing column on the card table will press the switch of the alarm module, activate the alarm, and remind the owner of the hand dryer.

[0020] Furthermore, at least one table groove is respectively provided on both sides of the main frame, and at least one main pushing plate is respectively provided in the table grooves on both sides of the main frame.

[0021] With such arrangement, at least one card stand is inserted into the card slot on each side of the rear cover of the hand dryer for positioning, and the hand dryer is more firmly connected.

[0022] Furthermore, four table grooves are respectively provided on both sides of the main frame.

[0023] With such a setting, the four table grooves on both sides correspond to the four fingers of both hands except the thumbs. The hand dryer is more firmly connected, and more types of passwords can be set. Description of the Drawings
