[0027] Refer to Figure 1 According to the hand dryer for reducing water droplet splashing of the embodiment of the utility model, including shell 100 and air supply device 200, shell 100 is provided with hand drying space 110, and the inner wall of one side of hand drying space 110 is provided with water collecting groove 120;Air supply device 200 is arranged in shell 100, and air supply device 200 has air outlet 221 and air inlet 222;Wherein, air outlet 221 is arranged on the opposite two side inner walls of hand drying space 110 one by one corresponding to water collecting groove 120, and air inlet 222 is arranged on the inner wall of one side of hand drying space 110.

[0028] The hand dryer provided by the utility model can be used in the specific use process, and then the air supply device 200 blows air from the air outlet 221 to dry the hands of people, and part or all of the water droplets blown off from the hands of people are received by the water collecting groove 120 opposite to the air outlet 221, so that the splashing of water droplets in the hand drying process is reduced, and at the same time, the air inlet 222 is arranged on the inner wall of one side of the hand drying space 110 to form air backflow in the hand drying space 110, compared with the air blown out by the air outlet 221 in the prior art, which is easy to cause the splashing of water droplets, the air backflow has smaller effect on the splashing of water droplets, so that the splashing of water droplets is further reduced, in addition, the air sucked by the air outlet 221 can flow over the hands of people to take away part of the water vapor on the hands of people, so that the hand drying speed can be improved, and under the blocking effect of the side wall of the hand drying space 110 and the hands of people, the suction of external matters from the air inlet 222 can also be reduced.

[0029] According to some embodiments of the utility model, the air supply device 200 is located on the side of the hand drying space 110 away from the water collecting groove 120, and the air inlet 222 and the air outlet 221 are arranged on the same side inner wall of the hand drying space 110. By adopting the above arrangement, the air supply device 200 is more easily assembled in the shell 100.

[0030] It is conceivable that, in other embodiments, the air inlet 222 may also be provided on the inner wall of the hand drying space 110 opposite to the inlet and outlet 111 of the hand drying space 110 .

[0031] According to some embodiments of the present invention, the hand-drying space 110 has an inlet and outlet 111 for hand entry and exit. The inlet and outlet 111 is located between the water receiving trough 120 and the air supply port 221. The air inlet 222 is located on the side of the air supply port 221 facing away from the inlet and outlet 111. Therefore, during the hand-drying process, the air delivered by the air supply port 221 is outside the air drawn in by the air inlet 222. The air delivered by the air supply port 221 forms a wind wall to further reduce the possibility of external debris being drawn into the air inlet 222.

[0032] According to some embodiments of the present invention, an air supply device 200 includes a fan 210 and a duct member 220 that cooperates with the fan 210. An air inlet 222 and an air outlet 221 are provided on the duct member 220. One end of the internal flow channel of the fan 210 is connected to the air inlet 222 and the other end is connected to the air outlet 221. The fan 210 is used to pump air from the air inlet 222 into the air outlet 221. This makes the entire air supply device 200 simpler in structure and easier to assemble.

[0033] According to some embodiments of the present invention, the air supply device 200 also includes a filter module 230, which is detachably inserted into the housing 100, and part or all of the filter module 230 is located on the flow channel between the fan 210 and the air inlet 222. Thus, the air inhaled by the air supply device 200 can be filtered by the filter module 230, and the filter module 230 is easy to replace.

[0034] In some embodiments, the filter module 230 and the air inlet 222 are disposed on the same inner wall of the hand drying space 110 .

[0035] like Figure 1 As shown, in the specific implementation process, the rear side of the casing 100 is used to be installed on the wall, the inlet and outlet 111 of the hand drying space 110 is located on the front side of the casing 100, the water receiving tank 120 is located on the lower inner wall of the hand drying space 110, and the air supply port 221, the air inlet 222 and the filter module 230 are arranged on the upper inner wall of the hand drying space 110.

[0036] In a specific implementation process, the air inlet 222 includes one or more air inlet holes 2221 , and the air supply port 221 includes one or more air supply holes 2211 .

[0037] It is conceivable that, in other embodiments, the air inlet 222 and the air supply outlet 221 may be provided on different components. In this case, the control panel 300 may be installed between the air inlet 222 and the air supply outlet 221 .

[0038] According to some embodiments of the present invention, a control panel 300 is included. The control panel 300 is electrically connected to the air supply device 200 and is installed on one inner wall of the hand drying space 110. The control panel 300 is used to control the operation of the air supply device 200 to facilitate the staff to control the hand dryer.

[0039] According to some embodiments of the present invention, the control panel 300 and the air outlet 221 are arranged on the same inner wall of the hand drying space 110. Therefore, the control panel 300 and components of the air supply device 200 such as the air duct member 220 are assembled in one place, making the hand dryer more convenient to assemble.

[0040] According to some embodiments of the present invention, the air supply device 200 is equipped with a heating element 400 for heating air. This allows the hand dryer to use hot air to dry hands, improving the hand-drying speed. The air supply port 221 delivers hot air to the hand-drying space 110, while the air inlet 222 draws air from the hand-drying space 110 to recover heat. This reduces heat waste and the total power consumption of the heating element 400 during the hot air drying process, thereby achieving energy savings.

[0041] According to some embodiments of the present invention, the control panel 300 is provided with a main power switch 310, a hot and cold air switch 320, and a sensor element 330. The sensor element 330 is used to detect a human hand to control the start or stop of the air supply device 200, and the hot and cold air switch 320 is used to control the start or stop of the heating element 400. Thus, the control panel 300 centrally provides the main power switch 310, the hot and cold air switch 320, and the sensor element 330, simplifying the internal circuitry of the hand dryer and facilitating the control of the hand dryer's operation.

[0042] Among them, the staff can control the main power on and off of the entire hand dryer through the main power switch 310, so that the hand dryer is in an overall power-off state or standby state. In the standby state, if a hand reaches into the hand drying space 110, the sensing element 330 can detect the hand and send a signal to the control panel 300. The control panel 300 controls the air supply device 200 to automatically start or stop working according to the signal detected by the sensing element 330. The hot and cold air switch 320 controls whether the heating element 400 works during the operation of the air supply device 200, thereby realizing the switching between the cold air drying and hot air drying modes.

[0043] Some embodiments of the present invention include a water tray 500 located on the side of the water trough 120 facing away from the hand drying space 110. The water tray 500 is detachably connected to the housing 100 and communicates with the water trough 120. Consequently, water received by the water trough 120 is stored in the water tray 500, which is concealed within the housing 100. This eliminates the need for the water trough 120 to store water, preventing the water from becoming contaminated by external debris while stored in the water tray 120, which could negatively impact the user's visual experience. After the hand dryer has been used for a period of time, the water tray 500 can be removed from the housing 100 to discard the water inside.

[0044] Of course, in other embodiments, the water receiving tank 120 may also be connected to a hose, and the water in the water receiving tank 120 may be discharged to other places through the hose.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
