Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
It should be noted that all the directional indicators (such as up, down, left, right, front, back, 8230; \8230;) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise explicitly specified or limited. For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or through an intervening medium, or through internal communication between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1-2, the improved structure for preventing liquid leakage of the water outlet of the hand washing machine of the embodiment includes a water tank water outlet 1 and a main unit water inlet 2, the water tank water outlet 1 is inserted into the main unit water inlet 2, the outer wall of the water tank water outlet 1 is provided with a raised rib portion 11, the inner wall of the main unit water inlet 2 is provided with a recessed notch 21, and the rib portion 11 is arranged in the notch 21.
The outer wall of water tank faucet 1 is equipped with sealing washer recess 12, is equipped with sealing washer 3 in the sealing washer recess 12, and it is sealed through sealing washer 3 between water tank faucet 1 and the host computer intake opening 2, and the downside that sealing washer 3 is close to rib portion 11 and notch 21 junction sets up to shorten the distance that sealing washer 3 breaks away from 2 inner walls of host computer intake opening as far as possible.
As shown in fig. 3-4, the main body inlet nozzle 2 includes a water pump inlet 22, a water pump outlet 23, a water outlet cavity 24 and a foam outlet 25, the water pump inlet 22 is connected to the water inlet end of the water pump 4, the water pump outlet 23 is connected to the water outlet end of the water pump 4, and two ends of the water outlet cavity 24 are respectively connected to the water pump outlet 23 and the foam outlet 25.
A through water outlet channel 13 is arranged in the water outlet nozzle 1 of the water tank, one end of the water outlet channel 13 is connected with the water tank 6 through a hose 5, and the other end of the water outlet channel is connected with a water inlet 22 of the water pump.
When the water tank water outlet nozzle is used, the water tank water outlet nozzle 1 is inserted into the main machine water inlet nozzle 2, and the main machine water inlet nozzle and the main machine water outlet nozzle are sealed through the sealing ring 3. When the water pump 4 works, the hand sanitizer in the water tank 6 is pumped into the water pump 4 through the hose 5, the water outlet channel 13 and the water inlet 22 of the water pump, and is mixed with air in the water pump 4 to form foam, and the foam enters the water outlet cavity 24 through the water outlet 23 of the water pump and finally is discharged through the foam outlet 25 for a user to wash hands.
When the hand sanitizer in the water tank 6 is insufficient, the hand sanitizer needs to be supplemented, and the water outlet nozzle 1 of the water tank needs to be pulled out of the water inlet nozzle 2 of the main machine during the supplementation. Because the water pump 4 is in a sealed state and the inside of the channel formed by the hose 5, the water outlet channel 13, the water inlet 22 of the water pump and the water inlet end of the water pump 4 is filled with liquid in the working process, in the process of pulling out the water outlet nozzle 1 of the water tank, a negative pressure is formed between the water outlet nozzle 1 of the water tank and the water inlet nozzle 2 of the main machine due to the existence of the sealing ring 3 in the traditional sealing structure, and the liquid in the water pump 4 is sucked out to wet the main machine shell.
And this patent is because the cooperation of muscle portion 11 and notch 21 between water tank faucet 1 and the host computer intake nozzle 2, and the distance of 3 distance two junctions of sealing washer is very close, consequently in the twinkling of an eye of extracting water tank faucet 1, the very first time entering of air is by hose 5, exhalant canal 13, the airtight passageway that the end constitutes of intaking of water pump water inlet 22 and water pump 4, balance this passageway internal pressure and outside atmospheric pressure, thereby avoid leading to the liquid outflow in the water pump 4 to pollute the host computer because of inside and outside pressure differential, the user experience of hand washer has been improved.
In addition, in the process of outwards pulling out the water tank faucet 1, the rib parts 11 can also prevent the sealing ring 3 from falling off from the sealing ring groove 12 due to extrusion and friction, and therefore the sealing ring 3 can be limited.
The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
