Detailed Description

The following specific embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can modify the present embodiments as required after reading the present specification without any inventive contribution, but only protected by the patent laws within the scope of the appended claims.

The scheme is realized by the following technical means:

example (b): the embodiment provides a contact-free hand disinfection device, which comprises a steel mounting bracket 1, wherein the mounting bracket 1 can be divided into a support base plate 1a fixedly placed on the ground and a mounting platform 1b arranged above the support base plate 1a, the two parts are in a flat plate state, the support effect of the support base plate 1a relative to the ground and the stable support effect of the mounting platform 1b relative to the upper part arranged on the support base plate can be realized, the support base plate 1a and the mounting platform 1b are connected and fixed through a support column 1c extending along the vertical direction, and all parts of a set of pressure type disinfectant spraying system 2 are respectively fixedly arranged at different positions of the mounting bracket 1.

The biggest difference between the pressure type disinfectant spraying system 2 in the non-contact hand disinfecting and killing device in the scheme and the conventional disinfectant spraying and disinfecting device in the whole structure is that the device adopts a mode of mutually separating in space to set different working units, namely, a pressurizing driving unit 3 in one set of pressure type disinfectant spraying system 2 is arranged on a support base plate 1a close to the ground, a disinfecting and killing spraying unit 4 is arranged on a mounting platform 1b with a higher height position, and meanwhile, the two units are mutually connected through a hollow air guide hose 2a and a disinfectant storage tank 5 is arranged at the disinfecting and killing spraying unit 4.

Specifically, the pressurizing drive unit 3 provided here includes a drive pedal 3a to be stepped on by a user and a squeeze cylinder 3b in the pressurizing drive unit 3. One end of the driving pedal 3a is fixedly connected with the support base plate 1a in a hinged mode, a return spring 3c supported between the driving pedal 3a and the support base plate 1a is fixedly installed below the driving pedal 3a, and the return spring 3c is a compression spring and can provide reverse acting force to enable the driving pedal 3a to reversely rotate and return to the original position after being stepped and rotating around a fixed hinged central point. The squeezing type air cylinder 3b used here comprises a main cylinder body and a piston rod and works in a reciprocating type telescopic motion mode, and the device is mature and the component is not improved and optimized in the scheme, so that the details are not repeated. In the pressurizing drive unit 3, the squeeze cylinder 3b is laid on the aforementioned holder base plate 1a, and one end of a piston rod in the squeeze cylinder 3b faces the drive pedal 3a side and is connected to the upper end of the aforementioned drive pedal 3a by a connecting rod. It should be noted here that both ends of the connecting rod are also movably connected with the end of the piston rod and the upper end of the driving pedal 3a in a hinged manner, so that the driving pedal 3a can carry the piston rod to reciprocate when rotating in the forward and reverse directions, and further drive the extrusion type air cylinder 3b to work.

The rear part of the extrusion type air cylinder 3b is the air outlet end of the main cylinder body, and compressed air generated by the operation of the extrusion type air cylinder 3b is conveyed upwards to the position of the sterilizing and spraying unit 4 by a hollow air guide hose 2a made of rubber. Because the air guide hose 2a is made of soft material and is easy to swing unstably in the process of conveying air, the air guide hose 2a can be clamped and fixed on the supporting column 1c through a binding buckle 201. For example, the lashing buckle 201 may be a steel semicircular arc sheet, which is formed with a closing section having a width smaller than the radial dimension of the support column 1c and has excellent elastic deformation performance, and the air guide hose 2a and the support column 1c can be quickly connected and fixed only by pressing and buckling.

The disinfecting and sterilizing spraying unit 4 arranged on the mounting platform 1b mainly comprises a disinfecting and sterilizing box 4a with a hollow interior, an opening for the hand of the medical staff to extend into is arranged on one side of the disinfecting and sterilizing spraying unit, and a disinfecting liquid spraying head with a downward opening is arranged at the top of the inner cavity of the disinfecting and sterilizing box 4 a. A series of pipeline structures are formed above the sterilizing box 4a and are used for completing the disinfectant spraying action on the hands of the medical personnel by taking compressed air transmitted by the lower extrusion type air cylinder 3b through the air guide hose 2a as power.

The disinfection box is characterized in that an inverted disinfection liquid storage tank 5 with a downward opening is fixedly mounted above the disinfection box, and the disinfection liquid storage tank 5 is fixedly mounted above the disinfection box through a thread screwing structure 5a for convenient disassembly and replacement. The opening of the disinfectant storage tank 5 extends to the upper part of the disinfectant spraying head through the hollow fluid guide channel 4c and is communicated with the disinfectant spraying head, and a disinfectant temporary storage cavity 4b which is larger than the radial dimension of the fluid guide channel 4c is arranged above the disinfectant spraying head. Meanwhile, the air guide hose 2a is also connected to the temporary disinfectant storage chamber 4b, and a first one-way air valve 7 which can be opened only under a certain pressure is arranged at the tail end of the air guide hose 2 a.

Under this structure, the disinfection solution in the disinfection solution storage tank 5 will flow first and fill the disinfection solution temporary storage cavity 4b, and meanwhile, as the opening of the disinfection solution sprinkler head is small, no dripping phenomenon occurs in a non-use state. At this time, the medical staff, as a user, first inserts his or her hand into the sterilizing chamber 4a and then steps on the aforementioned driving pedal 3a, so that the pressurized air generated by the squeeze air cylinder 3b is delivered to the disinfectant temporary storage chamber 4b through the air guide hose 2 a. Along with the squeezing and treading of the user, the first one-way air valve 7 is opened at a certain moment, so that the disinfectant is sprayed and disinfected to the hands of the medical staff through the disinfectant spraying head under the action of the pressurized air to complete the disinfection work.

Furthermore, due to the limitation of the overall volume and size of the device, the inner diameter of the liquid guiding channel 4c connected to the disinfectant storage tank 5 cannot be set too large, and at this time, the situation that the disinfectant is not smoothly circulated in the liquid guiding channel 4c or even cannot fill the disinfectant temporary storage cavity 4b occurs. In consideration of the situation, an auxiliary channel 4d communicated with the outside is also connected and led out in the temporary disinfectant storage cavity 4b, and a second one-way air valve 5b which plays a role of compensating air suction into the disinfectant storage tank 5 is arranged at the bottom of the disinfectant storage tank. At the moment, the two ends of the disinfection solution in the pipeline are communicated with the outside, so that smooth flowing work of the disinfection solution can be ensured.

In this case, however, leakage of the disinfecting liquid from the auxiliary passage 4d may occur due to the hydraulic pressure inside the disinfecting liquid storage tank 5. Therefore, further, a switch assembly 6 is also provided above the sterilization case. The switch assembly 6 comprises a control member 6b, the control member 6b is arranged in a cavity, the upper part of the cavity is communicated with the air guide branch pipe 6a, a supporting spring 6c is arranged below the control member 6b, a through hole 601 capable of being communicated with the auxiliary channel 4d sections at two sides is formed in the upper part of the control member 6b, the control member 6b can move up and down under the combined action of the pneumatic action of the air guide branch pipe 6a and the supporting spring 6c, and the opening or the closing of the auxiliary channel 4d is controlled. It should be noted that the opening air pressure of the first one-way air valve 7 is greater than the air pressure when the air branch tube 6a drives the control member 6b to move down to make the auxiliary channel 4d enter the closed state. Under the structure, when a user steps on the driving pedal 3a, before disinfectant is sprayed outwards through the disinfectant spraying head, the air pressure generated by the air guide branch pipe 6a can drive the control component 6b to move downwards and close the auxiliary channel 4d, so that a closed state is formed inside the pipeline, at the moment, the first one-way air valve 7 can be opened only by continuously stepping on the driving pedal to realize disinfectant spraying action, and a reliable and stable leakage-proof effect is realized by utilizing a simple design.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
