DETAILED DESCRIPTION
[0039] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.
[0040] The present application discloses a hand washer. In some examples, the hand washer disclosed in the present application includes a housing 11, a partition 12, a delivery pump 13, a storage tank 14, an annular foaming chamber 2, a detection sensor 3 and an air pump 4. The shape of the housing 11 is as follows: Figure 1 As shown, the shell 11 has two functions. The first function is to be installed on a door or a wall in order to provide a suitable operating height and avoid contact with flat surfaces such as countertops; the second function is to provide a working environment for the delivery pump 13, the storage tank 14, the annular foaming chamber 2 and the detection sensor 3.
[0041] See also Figure 2 The partition 12 is located in the shell 11, dividing the space in the shell 11 into an operating space and a storage space. The delivery pump 13 is fixedly installed in the shell 11. Generally, the delivery pump 13 is deployed in the storage space. The input end of the delivery pump 13 is located in the storage space, and the output end is located in the operating space.
[0042] The storage tank 14 is fixedly installed in the storage space and connected to the input end of the delivery pump 13. The annular foaming chamber 2 is fixed in the operating space and connected to the output end of the delivery pump 13. The delivery pump 13 delivers the liquid (hand sanitizer, hand sanitizer with disinfection function or special function) stored in the storage tank 14 into the annular foaming chamber 2.
[0043] The detection sensor 3 is installed in the operating space. In terms of position, the detection sensor 3 is located behind the annular foaming chamber 2 in the direction close to the back of the shell 11. Here, the back of the shell 11 refers to the surface of the shell 11 that is in direct contact with the door or wall.
[0044] The air pump 4 is also installed in the operating space. The air pump 4 is connected to the annular foaming chamber 2 and has the function of sending air into the annular foaming chamber 2 for foaming with the liquid.
[0045] Figure 2 The thick solid lines in the figure represent pipelines, including gas pipelines and liquid pipelines.
[0046] In some possible implementations, the detection sensor 3 uses a laser sensor, which includes a receiver and a transmitter. If the signal emitted by the transmitter is detected by the receiver, it means that no one is using it at this time, otherwise it means that someone is using it, such as Figure 3 and Figure 4 shown.
[0047] The function of the detection sensor 3 is to transmit an opening signal and a closing signal.
[0048] In combination with a specific usage process, the user moves the hand to the front of the operating space, and then extends the hand into the operating space. At this time, the detection sensor 3 senses the entry of the hand, and the delivery pump 13 and the air pump 4 are started to deliver liquid and air into the annular foaming chamber 2 at the same time.
[0049] The user's hand passes over the detection sensor 3 and extends into the annular foaming chamber 2. The foam produced by the annular foaming chamber 2 falls evenly on the user's hand. During the forward and backward movement, the user's hand is fully covered by the foam.
[0050] The above process can achieve full coverage of the cleaning area. At the same time, the handwashing machine in this application does not have any contact with the user's hands during the entire process, which not only ensures the cleaning requirements, but also avoids potential cross-infection that may occur when different users use it.
[0051] For some examples, see Figure 5 The annular foaming chamber 2 includes an annular foaming ring 21, a liquid delivery channel 22, a return channel 23, a gas delivery channel 24 and a foaming member 25. The annular foaming ring 21 is fixed inside the operating space, and the liquid delivery channel 22 and the gas delivery channel 24 are both located inside the annular foaming ring 21.
[0052] There are a plurality of foaming pieces 25 , which are evenly arranged on the annular foaming ring 21 . The foaming pieces 25 are connected to the liquid delivery channel 22 and the gas delivery channel 24 .
[0053] In some possible implementations, the number of foam parts 25 is six or eight.
[0054] The two ends of the return channel 23 are connected to the liquid delivery channel 22 and the storage tank 14 respectively, so as to keep the liquid in the liquid delivery channel 22 in a continuous flow state.
[0055] It should be understood that the function of the liquid delivery channel 22 is to provide liquid to multiple foaming parts 25 at the same time. Therefore, the liquid in the liquid delivery channel 22 needs to be in a continuous flow state during use, with part of the liquid entering the foaming part 25 and part returning to the storage tank 14.
[0056] In this way, the pressure at various locations in the liquid delivery channel 22 can be made uniform, and the amount of foam provided by the foaming member 25 can also be made consistent.
[0057] For some examples, see Figure 6 The foaming member 25 includes a main body 251, a foaming chamber 252, a foaming net 253, a first channel 254 and a second channel 255. The main body 251 is connected to the annular foaming ring 21 in a detachable manner, such as a threaded connection.
[0058] The foaming chamber 252 is located in the main body 251 . A foaming net 253 is provided in the foaming chamber 252 . When the liquid and the gas pass through the foaming net 253 , the two can be fully mixed to generate foam.
[0059] The two ends of the first channel 254 are respectively connected to the liquid delivery channel 22 and the foaming chamber 252, and the function is to provide liquid to the foaming chamber 252. The two ends of the second channel 255 are respectively connected to the gas delivery channel 24 and the foaming chamber 252, and the function is to provide gas to the foaming chamber 252.
[0060] The first channel 254 and the second channel 255 are both located on the same side of the foaming net 253 .
[0061] In some possible implementations, there are two foaming nets 253 and there is a gap between the two foaming nets 253 in order to achieve more sufficient foaming.
[0062] In some possible implementations, the pore size of the first foaming net 253 tends to decrease in the direction away from the first channel 254 and the second channel 255, in order to block the liquid when not in use and prevent the liquid from entering the foaming chamber 252.
[0063] Furthermore, in the direction away from the first channel 254 and the second channel 255 , the pore size of the second foaming net 253 remains unchanged.
[0064] Furthermore, in a direction away from the first channel 254 and the second channel 255 , the pore size of the second foaming net 253 is equal to the minimum pore size of the first foaming net 253 .
[0065] Regarding the control of the delivery pump 13 and the air pump 4, the specific implementation method is: the delivery pump 13 and the air pump 4 are connected to the power supply through a relay, and the detection sensor 3 is connected to the control end of the relay to generate high level and low level. The high level and low level can control the attraction and disconnection of the relay, thereby realizing the simultaneous startup and shutdown of the delivery pump 13 and the air pump 4.
[0066] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
