Description

Voice controlled smart wheelchair

The present invention relates to a voice-controlled smart wheelchair, and in particular, to a voice-controlled smart wheelchair that assists handicapped persons with mobility impairments by controlling alcohol spray at any time to disinfect their hands through voice control.

According to the general situation, disabled people who are wheelchair users often use their own hands to push the wheelchair forward, which often results in dirt and bacteria on their hands. Furthermore, disabled people spend most of their time in a sitting position, making it difficult to find alcohol spray bottles. If the hand disinfection is carried out at the appropriate placement position, if the bacteria on the hands are unconsciously infiltrated into the human body while eating, the disabled person will be at risk of contracting the disease or other bacterial infections.

In view of the above phenomenon, the creator of this case invented the best practical invention based on many years of production experience.

That is, the main purpose of the present invention is to provide a voice-controlled smart wheelchair; the problem it intends to solve is that it is difficult for disabled people to find the location of the alcohol spray bottle to carry out hand movements because they spend most of their time in a sitting position. Disinfection, if the bacteria on the hands can easily infiltrate into the human body unconsciously while eating, causing the risk of epidemics or other bacterial infections for the disabled, it should be improved and broken;

Its technical features to solve the problem include a wheelchair with a push rod on the rear side, one or two front wheels and two rear wheels on the bottom of the wheelchair, a seat at an appropriate position, and a disinfection unit at opposite sides of the seat. , the sterilization unit includes two opposite armrests, each armrest has a chamber embedded inside, and the chamber is filled with liquid content. There is a filling hole on the back side of the chamber, and the filling hole is upright and opened upward. The filling hole A lock cover is provided at the top of the lock, and an electric cylinder is provided at the other end of the chamber. One end of the electric cylinder is connected to a nozzle through a pipeline, so that the nozzle is exposed outside the handrail; a voice control unit is located therein A predetermined position on one side of the armrest, the voice control unit has a voice input module, the voice input module is respectively coupled to the electrical cylinders of the two disinfection units through a transmission line, and the preset is input through the voice input module The voice message is used to activate the action of the voice control unit, and the activation message is sent to the electric cylinders of the two sterilization units through each transmission line, so that the liquid content is sprayed out from the nozzle.

In this way, the present invention uses the wheelchair to perform hand disinfection actions through the alcohol of the voice-controlled disinfection unit. The disinfection unit of the present invention is hidden and does not take up space, and the voice control unit is also lightweight and attached to the position opposite the armrest. The user By placing your hands against the handrails, you can disinfect your hands and reduce the risk of infection for people with disabilities who have limited mobility.

Figure 3: This is the second action diagram of the voice-controlled smart wheelchair of the present invention, which shows that the nozzle has been activated.

Please refer to Figures 1 to 3, which are the preferred implementations of the voice-controlled smart wheelchair of the present invention. Examples, however, these examples are for illustrative purposes only and are not limited by this structure in patent applications, including:

A wheelchair 10 is provided with a push rod 11 on the rear side. The bottom of the wheelchair 10 is provided with one or two front wheels 13 and two rear wheels 12. A seat 14 is provided at an appropriate position. A disinfection unit 20 is provided at opposite positions on both sides of the seat 14. , the sterilization unit 20 includes two opposite armrests 21, each armrest 21 has a chamber 22 embedded inside, and the chamber 22 is filled with liquid content, wherein the inner chamber 22 of the armrest 21 of the sterilization unit 20 provides The liquid content is alcohol for disinfection. A filling hole 23 is provided on the rear side of the container 22. The filling hole 23 is upright and opens upward. A lock cover 231 is locked at the top of the filling hole 23 to replenish the alcohol. For liquid contents, the other end of the chamber 22 is provided with an electric cylinder 24. One end of the electric cylinder 24 is connected to a nozzle 26 through a pipeline 25, so that the nozzle 26 is exposed outside the handrail 21. The preferred implementation is as follows The nozzle 26 is located at the front end of the handrail 21;

A voice control unit 30 is provided at a predetermined position on one side of one of the handrails 21. The voice control unit 30 has a voice input module 31. The voice input module 31 is respectively coupled to the two disinfection units through a transmission line 27. The electric cylinder 24 of 20 inputs a preset voice message through the voice input module 31 to activate the voice control unit 30. The preset voice message can be "disinfect" or "hand disinfection", and The activation message is sent to the electric cylinders 24 of the two disinfection units 20 through each of the transmission lines 27, so that the liquid content is sprayed out from the nozzle 26, so that the user of the wheelchair 10 for the disabled can spray alcohol out through voice control. Those who perform hand disinfection.

In this way, the wheelchair 10 performs hand disinfection through the alcohol of the voice-controlled disinfection unit 20. The disinfection unit 20 of the present invention is concealed and does not take up space, and the voice control unit 30 is also lightweight and attached to the opposite position of the armrest 21. , when the user's hands are pressed against the handrail 21, the hands can be disinfected and the risk of infection of the disabled person with reduced mobility can be reduced.

To sum up the above description, the above-mentioned structure of the present invention can effectively overcome the shortcomings faced by conventional inventions, and further has the above-mentioned numerous advantages and practical value. Therefore, the present invention is an excellent creative structure, and has not been used in the same technical field. I have seen the invention or public use of identical or similar products, so this invention has met the requirements of "novelty" and "progress" for an invention patent, and the application is filed in accordance with the law.
