Hand sanitizer dispenser

Abstract

This invention is a hand sanitizer dispenser including a hand sanitizer bucket, a storage chamber, a liquid suction pipe, a push-type liquid suction pump, a liquid outlet pipe, a support base, a hollow vertical pole, a transmission rod assembly and a pedal mechanism; the push-type liquid suction pump is arranged at an upper end of the hollow vertical pole; pedal operation of the pedal mechanism can drive the transmission rod assembly to push up and press the push-type liquid suction pump, thereby causing the push-type liquid suction pump to suck the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe and spray it out through the liquid outlet pipe. It prevents the user from directly touching the device when getting the hand sanitizer, which can further prevent cross-infection among users, thus ensuring hygiene and health.

What is claimed is: 
     
         1 . A hand sanitizer dispenser, characterized in that: it comprises a hand sanitizer bucket, a storage chamber, a liquid suction pipe, a push-type liquid suction pump, a liquid outlet pipe, a support base, a hollow vertical pole, a transmission rod assembly and a pedal mechanism; the hollow vertical pole and the storage chamber are both arranged on the support base; the hand sanitizer bucket is stored in the storage chamber; the hand sanitizer bucket is filled with hand sanitizer; the liquid suction pipe has a first end which communicates with the hand sanitizer bucket and a second end which communicates with a liquid inlet of the push-type liquid suction pump; the push-type liquid suction pump is arranged at an upper end of the hollow vertical pole; the liquid outlet pipe has a first end which communicates with a liquid outlet of the push-type liquid suction pump and a second end which is exposed outside the hollow vertical pole; the transmission rod assembly is arranged in the hollow vertical pole in a vertically movable manner; the transmission rod assembly has an upper end which abuts against the push-type suction pump in transmission and a lower end which cooperates with the pedal mechanism in transmission; the pedal mechanism is arranged on the support base, and pedal operation of the pedal mechanism can drive the transmission rod assembly to push up and press the push-type liquid suction pump, thereby causing the push-type liquid suction pump to suck the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe and spray it out through the liquid outlet pipe. 
     
     
         2 . The hand sanitizer dispenser as in  claim 1 , wherein it further comprises a pressing handle rotatably pivoted on a side of an upper part of the hollow vertical pole; the pressing handle has a first end which extends into the hollow vertical pole to cooperate with the transmission rod assembly in transmission and a second end which is a pressing end and is exposed outside the hollow vertical pole; pressing operation of the pressing end of the pressing handle can also drive the transmission rod assembly to push up and press the push-type liquid suction pump, thereby causing the push-type liquid suction pump to suck the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe and spray it out through the liquid outlet pipe. 
     
     
         3 . The hand sanitizer dispenser as in  claim 1 , wherein the push-type liquid suction pump comprises a pump body, a plunger, a plunger spring, and a pump cover; the pump body is provided with a pump cavity with an upward opening; the liquid inlet of the push-type liquid suction pump is arranged at a lower end of the pump body and communicates with the pump cavity; the plunger spring is arranged in the pump cavity, and a lower end of the plunger extends into the pump cavity and abuts against the plunger spring; an upper end of the plunger is exposed outside the pump cavity; the liquid outlet of the push-type liquid suction pump is arranged at an insertion end of the plunger and communicates with the pump cavity; a liquid outlet channel connecting the liquid outlet and the liquid outlet pipe is formed in the plunger; the pump cover covers the upward opening of the pump body and can prevent the plunger from being axially separated from the pump cavity; the upper end of the transmission rod assembly abuts against the pump body; when the transmission rod assembly pushes upward and abuts against the pump body, the pump body moves upward relative to the plunger and squeezes out air in the pump cavity; when the transmission rod assembly returns downwards, the pump body returns downwards under action of the plunger spring and sucks the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe to spray it out through the liquid outlet pipe. 
     
     
         4 . The hand sanitizer dispenser as in  claim 3 , wherein the hollow vertical pole has an open top end which is equipped with a top cover; the upper end of the hollow vertical pole is also provided with an opening for the liquid outlet pipe to be exposed; an inner end of the liquid outlet pipe is connected with an abutment cap abutting against a lower end of the top cover; the upper end of the plunger abuts against the abutment cap. 
     
     
         5 . The hand sanitizer dispenser as in  claim 3 , wherein the transmission rod assembly comprises an upper transmission rod, a lower transmission rod and an intermediate connecting disc; the upper transmission rod has an upper end which abuts against the pump body and a lower end which abuts against the intermediate connecting disc; the lower transmission rod has an upper end which abuts against the intermediate connecting disc and a lower end which cooperates with the pedal mechanism in transmission; the second end of the liquid suction pipe which corresponds to the push-type liquid suction pump passes through the intermediate connecting disc and the upper transmission rod to communicate with the liquid inlet of the push-type liquid suction pump. 
     
     
         6 . The hand sanitizer dispenser as in  claim 5 , wherein a stand is provided on the support base, and a lower end of the hollow vertical pole is fixed on the stand; the pedal mechanism comprises a pedal and a pedal reset spring, and the pedal is hinged on the stand; the pedal has a first end which extends into the hollow vertical pole to cooperate with a bottom end of the lower transmission rod in transmission, and a second end which is a stepping end and is exposed outside the hollow vertical pole. 
     
     
         7 . The hand sanitizer dispenser as in  claim 6 , wherein the bottom end of the lower transmission rod is fixedly connected with a transmission abutting member, and two bottom sides of the transmission abutting member are respectively provided with a first abutting mating surface and a second abutting mating surface, each of which has a concave arc-shaped structure; the pedal has an inserting end which is provided with a left abutting block and a right abutting block, each of which has a concave arc-shaped structure; the left and right abutting blocks are in abutting cooperation with the first abutting mating surface and the second abutting mating surface. 
     
     
         8 . The hand sanitizer dispenser as in  claim 6 , wherein a guide pole is provided in the hollow vertical pole, and a lower end of the guide pole is fixed on the stand; the lower transmission rod is slidably sleeved on the guide pole in a vertically movable manner. 
     
     
         9 . The hand sanitizer dispenser as in  claim 1 , wherein the hollow vertical pole has an outer wall which is provided with a liquid receiving box below and corresponding with an outlet of the liquid outlet pipe; the upper end of the hollow vertical pole is also fixedly provided with a billboard on a side facing away from the liquid outlet pipe; the support base is provided with fixing holes for fixed connection with an external supporting surface.
