Description

Table type automatic hand sanitizer machine

Technical Field

The utility model relates to a technical field of liquid soap product especially relates to a not only can auto-induction go out foam, liquid soap when not enough but also can conveniently add the desk-top automatic liquid soap machine that can go out the foam automatically after the liquid soap response.

Background

At present, hand sanitizer extruded products for spraying hand sanitizer in the market have the traditional structure of only a hand sanitizer bottle and also have the product structure of a hand sanitizer machine with the hand sanitizer bottle. The traditional liquid soap bottle mainly adopts a hand pressing type structure, liquid can be discharged only by pressing with hands, the discharged liquid is pure liquid and is rubbed into foam by hands, and the discharged liquid is in a foam state. The liquid outlet pump and the like are used for achieving the effect of automatic liquid outlet, so that the liquid washing machine is convenient and direct; however, the existing hand sanitizer machine also has some defects, which are as follows: (1) When liquid needs to be discharged, the liquid discharging pump is still required to be started by manually touching the liquid discharging switch or pressing the liquid discharging switch to achieve automatic liquid discharging, and the effect of automatic liquid discharging without touching the liquid washing machine cannot be achieved (because the traditional liquid washing machine is of a square or cylindrical structure, an induction switch cannot be arranged on the side face, otherwise, the induction switch is triggered by mistake, so that frequent liquid discharging errors are caused, and the induction switch is also easily triggered by the induction switch arranged on the top face, so that liquid discharging errors are caused). (2) When the storage capacity of the hand sanitizer machine is insufficient and hand sanitizer needs to be added, two adding modes are basically provided, wherein one mode is to directly add the hand sanitizer through an adding port on the hand sanitizer machine, and the other mode is to directly disassemble a hand sanitizer bottle or a hand sanitizer tank and the like in the hand sanitizer machine for adding; the first addition mode has the problems that when the adding port is too small, blockage or overflow and the like are easily caused during adding, liquid soap is wasted, the adding speed is slow and inconvenient, when the adding port is larger, moisture of the liquid soap is easily evaporated to cause the concentration of the liquid soap to be increased and sticky, liquid outlet is not smooth and blocked when the adding port is serious, and the like, and if a cover is arranged at the adding port, the problems of not tight sealing, easy deformation and the like of the cover are caused; the second addition method is inconvenient for taking out the liquid soap bottle or the liquid soap pot, because the liquid soap bottle and the like are generally placed inside the liquid soap machine (a hidden design is adopted in consideration of aesthetic property), the corresponding panel of the liquid soap machine needs to be detached, and then the liquid soap pot and the like are directly detached, and the space for tools or hands to enter the liquid soap machine is narrow, so that the liquid soap pot is inconvenient to take out. (3) After the liquid soap dispenser automatically discharges liquid, the liquid discharge pump is closed, certain liquid soap is remained in the liquid discharge pump, and when the liquid soap dispenser is not used for a long time, the remained liquid soap is bonded in the liquid discharge pump to form a colloid or solid and the like, so that a liquid discharge pipeline of the liquid soap is easily blocked; and it is difficult to wash the residual liquid soap in the liquid outlet pump basically under the condition of not disassembling the liquid outlet pump, which causes the difficulty and inconvenient washing of the residual liquid soap.

Therefore, there is a need for improvements in the existing dispenser designs that ameliorate the problems of the prior art.
