Technical Field
[0001] This utility model relates to the field of hand dryer technology, specifically a hand dryer with a mobile phone holder. Background Technology
[0002] In modern life, hand dryers, as a common bathroom appliance, are widely used in various settings such as hotels, restaurants, research institutions, hospitals, public entertainment venues, and home bathrooms. Their main function is to quickly dry hands after washing by delivering warm or high-speed air, effectively avoiding the cross-infection problems that can occur with towel drying and greatly improving the hygiene of the environment. With technological advancements and the diversification of people's needs, some hand dryers have begun to be equipped with phone holders, allowing users to place their phones while drying their hands, providing greater convenience.
[0003] However, existing hand dryers with phone holders have revealed many problems in actual use. For example, in special environments such as construction sites, after workers wash their hands, there are often impurities such as sand and gravel left on their hands. When using a hand dryer, the air blown out by the hand dryer will cause these sand and gravel to fly around. Since the design of the phone holder on the traditional hand dryer does not take this situation into full consideration, the sand and gravel may be blocked by the phone holder and fly back into the hand dryer. Over time, this will not only affect the normal operation of the blower components and other parts inside the hand dryer, leading to a decrease in the performance of the hand dryer, but may even cause damage to the hand dryer, increasing maintenance costs and the frequency of equipment replacement.
[0004] In public places with high foot traffic, such as shopping malls, the traditional hand dryer has a flawed design in terms of the gap between the phone holder and the air outlet due to the large number of people using it. The gap is too small, causing the airflow and heat from the hand dryer to concentrate between the two. When users dry their hands, their hands will heat up quickly, causing discomfort. They have to frequently put their hands in and out of the gap, which seriously affects the comfort and convenience of the hand drying experience. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a hand dryer with a mobile phone holder, which solves the problem that the mobile phone holder on traditional hand dryers is difficult to adjust the tilt angle according to different mobile phone placement conditions or usage environments.
[0006] To achieve the above objectives, this utility model provides a hand dryer with a mobile phone holder, including a housing, a blower assembly disposed inside the housing, and a holder disposed outside the housing. The top wall of the housing has an air outlet. The holder is composed of a base plate and a support plate. The base plate and the support plate are perpendicular to each other and connected. The support plate is positioned above the air outlet, and the bottom wall of the support plate and the top wall of the housing are fitted together to form a hand drying area for external users to place their hands. The top wall of the support plate has a placement groove for placing an external mobile phone. The base plate and the support plate are detachably connected to an adjustment structure for adjusting the relative tilt angle between the base plate and the support plate in different usage environments to adapt to different mobile phone placement conditions.
[0007] The advantages of adopting the above technical solution are as follows: By designing the bracket as consisting of a base plate and a support plate, and setting a detachable adjustment structure between the base plate and the support plate, the relative tilt angle between the base plate and the support plate can be flexibly adjusted according to different usage environments and mobile phone placement conditions. For example, in a construction site environment, the angle can be adjusted to reduce the obstruction of sand and gravel by the bracket, preventing sand and gravel from flying back into the hand dryer and ensuring the normal operation of the hand dryer; in shopping malls and other places with high traffic, the angle can be adjusted to increase the space of the hand drying area, optimize the airflow distribution, reduce the discomfort caused by concentrated airflow and heat on the hands, and improve the hand drying experience. At the same time, the placement slot on the support plate facilitates the placement of mobile phones, making the hand dryer both practical and convenient, meeting the diverse needs of users.
[0008] The present invention further comprises: a protrusion at the top of the substrate; two adjusting plates opposite each other at the ends of the support plate; the two adjusting plates being disposed at both ends of the protrusion; adjusting holes being provided on both end faces of the protrusion; the two adjusting holes being coaxially arranged; mating holes being provided on both adjusting plates; the two mating holes being coaxially aligned with their respective adjacent adjusting holes; the adjusting structure comprising two adjusting shafts being disposed at both ends of the protrusion; a first toothed groove being provided circumferentially on the inner peripheral wall of the adjusting hole; a second toothed groove being provided circumferentially on the inner peripheral wall of the mating hole; the adjusting shafts being respectively fitted into the adjusting hole and the mating hole; and a third toothed groove being provided on the outer peripheral wall of the adjusting shaft for meshing with the first toothed groove and the second toothed groove respectively when the adjusting shaft is fitted into the adjusting hole and the mating hole.
[0009] The advantages of adopting the above technical solution are as follows: The adjustment structure in the above technology uses a toothed meshing design of adjustment shaft, adjustment hole, and mating hole, which makes the angle adjustment operation between the substrate and the support plate simple and stable. Through the engagement of the third toothed groove with the first and second toothed grooves respectively, the support plate can be reliably fixed on the substrate after adjustment to a suitable angle, preventing angle deviation caused by external force or vibration during use. This design not only ensures the stability of the phone placement but also ensures the relative fixation of the hand-drying area space. Regardless of the usage environment, users can place their phones and dry their hands normally with confidence, effectively improving the reliability and user experience of the hand dryer. At the same time, the above technology can flexibly adjust the relative tilt angle between the substrate and the support plate according to different usage environments and phone placement conditions.
[0010] The present invention further comprises: the radial cross section of the outer peripheral wall of the protrusion is arranged in an arc shape; the end face of the support plate and the bottom wall of the support plate are connected by a smooth arc surface and form a self-aligning arc surface; the self-aligning arc surface is abutted against the outer peripheral wall of the protrusion.
[0011] The advantages of adopting the above technical solution are: the arc-shaped setting of the outer peripheral wall of the protrusion, combined with the self-aligning arc surface at the end of the support plate, makes the angle adjustment of the substrate and the support plate smoother. The smooth arc connection reduces the frictional resistance when the two rotate relative to each other, allowing users to easily and quickly complete the angle adjustment. At the same time, the abutting fit between the self-aligning arc surface and the outer peripheral wall of the protrusion further enhances the stability after angle adjustment, preventing the use from being affected by the difficulty of fine-tuning the angle or the loosening after adjustment.
[0012] This utility model further comprises: two connecting posts opposite each other on the back of the housing; connecting holes are provided on the base plate corresponding to the positions of the two connecting posts; each of the two connecting posts is inserted into its corresponding connecting hole; a plurality of deformable parts are arranged circumferentially at the beginning of the connecting posts; adjacent deformable parts are fitted with a gap and form a deformable groove; a through hole is passed through the connecting post along its axial direction; a connecting shaft is inserted into the through hole; the plurality of deformable grooves are connected to the through hole; threaded grooves are provided on the inner walls of the plurality of deformable parts; the plurality of threaded grooves are combined to form a first thread for threaded connection with the connecting shaft; the connecting shaft and the through hole cooperate to apply force to the inner wall of the deformable part so that the outer wall of the deformable part is tightly fitted with the inner peripheral wall of the connecting hole.
[0013] The advantages of adopting the above technical solution are: the unique design of the connecting hole between the connecting column and the substrate in the above technology, through the threaded connection between the connecting shaft and the deformation part, realizes the expansion and tightening fit between the connecting column and the substrate. This connection method is not only convenient for installation and disassembly, but also can firmly fix the bracket to the shell, ensuring the stability of the overall structure of the hand dryer. During use, even if it is subjected to external force collision or vibration, the bracket is not easy to loosen or fall off, effectively avoiding the impact of the hand dryer's use caused by the bracket's insecure connection. At the same time, it also extends the service life of the hand dryer and improves product quality and user satisfaction.
[0014] The present invention further includes: a damping pad is attached to the outer wall of the deformable part, the damping pad is made of elastic material, and the outer peripheral wall of the damping pad is tightly fitted with the inner peripheral wall of the connecting hole.
[0015] The advantages of adopting the above technical solution are as follows: The vibration damping pad on the outer wall of the deformable part, made of elastic material, effectively buffers vibration and external impact when the connecting column and connecting hole are tightened together. On the one hand, it reduces noise caused by vibration, creating a quieter operating environment for users; on the other hand, it reduces the risk of loosening or damage to parts due to vibration during operation, protecting internal components such as the blower assembly and extending the service life of the hand dryer. Simultaneously, the tightening of the vibration damping pad further enhances the stability of the connection between the bracket and the shell, ensuring reliable operation of the hand dryer in various usage scenarios.
