Background
The induction soap dispenser generally senses the hand position of a human body through an induction transmitter and an induction receiver, and supplies soap liquid to a user in a manner of controlling the driving of a soap liquid pump, but because a soap liquid outlet of the existing induction soap dispenser is generally of a simple pipeline type, part of soap liquid is easily left in the soap liquid outlet after the soap liquid is output, the moisture of the soap liquid is easily evaporated to form lumps and adhere to the inner wall of the soap liquid outlet, the blockage of the soap liquid outlet is caused, the extrusion flow of the soap liquid is seriously influenced, the soap liquid lumps formed by the lumps on the inner wall of the soap liquid outlet are easily flushed out of the soap liquid outlet along with the soap liquid, so that the solidified soap lumps and the liquid state soap liquid are taken by the user to rub the hand part and other places, the liquid state soap liquid can be foamed quickly and stains can be removed, the solidified soap lumps can be dissolved after absorbing the moisture, and therefore the soap lumps are difficult to adhere to the skin to rub, inconvenience is brought to the use of the user, and the use experience of the user is seriously influenced.
Disclosure of Invention
Based on the above problems, the present invention is directed to a pulsating type induction soap dispenser, which is not easy to leave residual soap at a soap dispenser and can prevent or reduce the caking of soap.
Aiming at the problems, the following technical scheme is provided: a pulsation type induction soap dispenser comprises a shell, wherein the shell is provided with a detachable soap liquid storage part, a soap liquid pump used for extracting soap liquid from the soap liquid storage part is arranged in the shell, the shell is also provided with a battery bin, an induction transmitter and an induction receiver, the battery bin, the induction transmitter and the induction receiver are used for storing a battery, a circuit board connected with the battery, the induction transmitter, the induction receiver and the soap liquid pump is arranged in the shell, the top of the shell is provided with a starting switch, a soap liquid flow channel is arranged on the shell, a liquid outlet of the soap liquid pump is connected with the soap liquid flow channel, a detachable silica gel membrane is arranged at an outlet of the soap liquid flow channel, and a slit is formed in; the liquid outlet is connected to the soap liquid flow channel in a vertically upward or inclined upward mode, an elastic volume expansion device is arranged at the upstream position of the soap liquid flow channel, when the soap liquid pump works, the pressure between the liquid outlet and the soap liquid flow channel rises to enable the elastic volume expansion device to expand and accumulate pressure in the direction connected with the atmosphere, the volume of the liquid outlet and the pressure in the soap liquid flow channel are increased at the same time, when the pressure between the liquid outlet and the soap liquid flow channel rises to the slit opening pressure threshold value of the silica gel membrane, the soap liquid pushes the silica gel membrane to deform under the output of the soap liquid pump to open the slit, the soap liquid is sprayed out from the soap liquid flow channel through the silica gel membrane, when the soap liquid pump finishes one pump liquid beat to stop pumping, the elastic volume expansion device recovers the original shape under the elasticity of the elastic volume expansion device to enable surplus soap liquid generated by expansion and accumulation to be sprayed out from the slit together, and at the moment, the pressure between the liquid outlet of the silica gel membrane and the soap liquid The slit is undisturbed and closed; the expansion volume of the elastic volume expansion device is smaller than the liquid outlet volume output by the soap liquid pump in a single liquid pumping beat.
In the structure, according to the problem that the residual soap liquid in the existing soap liquid outlet is easy to agglomerate, the silicone membrane sheet in the prior art is used as an opening and closing element of the soap liquid flow passage and is arranged in the soap liquid flow passage (the silicone membrane sheet structure refers to the structure of a bottle cap of a squeal sports beverage produced by farmer mountain spring), as the working condition of the silicone membrane sheet needs to meet certain pressure, a slit can be opened, the slit is opened under pressure, the soap liquid is sprayed out in a spraying state, and the slit can be closed in time and quickly cut off the soap liquid when the pressure is reduced to a certain threshold value, the situation that the adhesion and accumulation of the soap liquid at the outlet of the soap liquid flow passage cause the evaporation of water and the hardening and agglomeration is avoided; however, in the actual research and test process, the requirement that the soap solution is not completely adhered cannot be met by the silica gel film in the prior art, and the specific reasons are as follows: the pressure conditions of the using positions of the silica gel membranes are different, when the silica gel membrane is used for a common beverage plastic bottle, the slit is opened by increasing the pressure in the bottle by extruding the bottle body, after the slit of the silica gel membrane is opened, the pressure for opening the slit is kept to be smaller than the pressure at the moment of opening the slit, therefore, the pressure can be accumulated by utilizing the self space of the bottle body when the bottle body is extruded, the slit is kept to be continuously opened by the accumulated pressure, after the accumulated pressure is smaller than the pressure for maintaining the opening of the slit, the slit can be instantly closed, if the slit needs to be opened for the second time, the bottle body needs to be extruded again to increase the accumulated pressure, but when the silica gel membrane is used for a soap liquid dispenser, as the condition for accumulating pressure does not exist between the liquid outlet of the soap liquid pump and the soap liquid flow passage, under the condition that the soap liquid is filled in the liquid outlet and the soap flow, the soap is discharged from the slit of the silicone membrane, and there is no pressure difference between the opening moment of the silicone membrane and the opening state of the silicone membrane, which can cause the silicone membrane to reset to drive the slit to close after the pressure accumulation is reduced, because the volumes of the liquid outlet and the soap flow channel cannot be adjusted, the soap can continuously extrude a small amount of soap from the slit under the resetting and extrusion of the silicone membrane, so that the soap is not easily intercepted, and the soap is accumulated on the outer side of the silicone membrane to cause the phenomenon of drying and caking The volume of the compressed space (namely the compression sensitivity is insufficient), and meanwhile, the compressed space is an independent space body, and the space body is internally provided with compressible air, so that the situation that the volume of the air in the space body is changed due to the change of temperature and air pressure, and unstable factors are generated to cause liquid leakage and leakage of the silica gel membrane is caused; after a large number of tests are carried out, a second scheme is selected, namely, a condition which is communicated with the atmosphere and can change the volume is created, the problem of liquid leakage and leakage of the silicone membrane caused by the change of temperature and air pressure can be effectively solved, the expansion volume of the elastic volume expansion device is smaller than the liquid outlet volume output by the soap pump in a single pumping beat, and the silicone membrane can be opened on the premise that the liquid outlet volume of the soap liquid of the soap pump meets the volume of the soap liquid required by the expansion and pressure accumulation of the elastic volume expansion device when the soap pump outputs in a working beat; the liquid outlet is connected to the soap lye flow passage in a vertical upward or inclined upward manner, so that bubbles in the liquid outlet and the soap lye flow passage can float upward and be discharged or are discharged first, air in the liquid outlet and the soap lye flow passage can be discharged as far as possible, and the liquid leakage condition of the liquid leakage of the silica gel membrane caused by the change of temperature and air pressure can be reduced.
The invention is further arranged that one end of the soap liquid flow channel back to the liquid outlet extends vertically upwards or extends obliquely upwards to the highest point, the end part of the soap liquid flow channel is arranged close to the highest point and is obliquely downwards or vertically downwards, and the silica gel membrane is positioned at one end of the soap liquid flow channel, which is obliquely downwards or vertically downwards, and is arranged close to the end part of the soap liquid flow channel.
In the structure, the bubbles which accidentally enter the soap liquid flow passage can be accumulated at the highest point of the soap liquid flow passage, so that the bubbles can be discharged first when the slit of the silica gel membrane is opened.
The invention is further arranged that the slit opening pressure threshold of the silica gel membrane is greater than the pressure threshold for maintaining the slit open state.
In the above structure, the characteristic that the slit opening pressure threshold of the silica gel diaphragm is larger than the pressure threshold for maintaining the slit opening state is that the silica gel diaphragm is in the prior art.
The invention is further arranged in such a way that an expansion cavity is arranged at the upstream position of the soap liquid flow channel, which is provided with the silica gel membrane, an expansion window is arranged on the expansion cavity, and the elastic volume expansion device is an elastic rubber membrane arranged on the expansion window.
Among the above-mentioned structure, because the single pump liquid beat of soap lye pump belongs to the output process of a continuity, consequently the single output volume is great, need improve the soap lye storage volume when holding pressure through setting up the inflation chamber, the inflation chamber sets up the position preferred near the silica gel diaphragm, can make the elastic rubber membrane more sensitive to the extrusion dynamics of soap lye when the shrink after outside inflation pressure-holding, reduces the influence that the soap lye caused because of fluid resistance in the soap lye runner.
The invention is further arranged such that the opening of the expansion window faces the ground when the soap flow passage is inclined.
In the structure, the bubble in the soap liquid can be prevented from gathering in the elastic rubber film due to upward bulging when the elastic rubber film expands, and the bubble in the soap liquid can be guided to gather towards the highest position of the soap liquid flow passage.
The invention is further arranged that one surface of the elastic rubber film, which is back to the inner cavity of the soap liquid flow channel, is adhered with a plurality of uniformly distributed one-way expansion columns, and the one-way expansion columns are arranged closely and mutually abutted before the elastic rubber film expands and deforms.
In the structure, the unidirectional expansion columns are radially separated from each other and are expanded by the spacing distance when the elastic rubber film expands and deforms and protrudes outwards, so that the expansion of the elastic rubber film is not restricted, when the liquid pumping of the soap pump is finished, the elastic rubber film extrudes the pressure-accumulated soap liquid during the expansion under the action of the elasticity of the elastic rubber film out of the slit, and the soap pump does not work again for a long time or the soap liquid flows back due to a small amount of leakage inside the soap pump, a certain probability of negative pressure exists between the liquid outlet and the soap liquid flow passage, so that the elastic rubber film is sunken towards the inner wall direction of the soap liquid flow passage, and the unidirectional expansion columns can mutually extrude and abut against each other when the elastic rubber film is sunken towards the inner wall direction of the soap liquid flow passage to restrict the inward concave deformation of the elastic rubber film, so as to avoid the increase of the volume of the soap liquid required by the elastic rubber film in the pressure-accumulated state when the soap pump works again, the problem that the liquid cannot be discharged after pressing is easily induced.
The invention is further arranged that the cross section of the unidirectional expansion column is circular, isosceles triangle, square or hexagon.
In the above-mentioned structure, the preferred circular of one-way expansion post cross-section is cellular arrangement each other, can produce certain space between the circular one-way expansion post is adjacent and hold dust impurity, reduces between the one-way expansion post because of there being dust impurity and cause one-way expansion post can't draw close each other and lead to appearing influencing the elastic rubber membrane and reset the possibility not in place.
The invention is further arranged that the silica gel membrane is clamped at the outlet of the soap flow channel through a clamping ring.
In the structure, the silicon rubber diaphragm is convenient to replace when damaged.
The invention has the beneficial effects that: according to the problem that soap liquid remained in an existing soap liquid outlet is prone to caking, a silicon membrane sheet in the prior art is arranged in a soap liquid flow channel as an opening and closing element of the soap liquid flow channel (the structure of the silicon membrane sheet refers to the structure of a bottle cap of a Shai sports beverage produced by farmer mountain spring), as the working condition of the silicon membrane sheet needs to meet certain pressure, a slit can be opened, the slit is opened under pressure, the soap liquid is sprayed out in a spraying state, and the slit can be closed in time to cut off the soap liquid rapidly when the pressure is reduced to a certain threshold value, the situation that the adhesion and accumulation of the soap liquid at the outlet of the soap liquid flow channel cause water evaporation and hardening caking is avoided; however, in the actual research and test process, the requirement that the soap solution is not completely adhered cannot be met by the silica gel film in the prior art, and the specific reasons are as follows: the pressure conditions of the using positions of the silica gel membranes are different, when the silica gel membrane is used for a common beverage plastic bottle, the slit is opened by increasing the pressure in the bottle by extruding the bottle body, after the slit of the silica gel membrane is opened, the pressure for opening the slit is kept to be smaller than the pressure at the moment of opening the slit, therefore, the pressure can be accumulated by utilizing the self space of the bottle body when the bottle body is extruded, the slit is kept to be continuously opened by the accumulated pressure, after the accumulated pressure is smaller than the pressure for maintaining the opening of the slit, the slit can be instantly closed, if the slit needs to be opened for the second time, the bottle body needs to be extruded again to increase the accumulated pressure, but when the silica gel membrane is used for a soap liquid dispenser, as the condition for accumulating pressure does not exist between the liquid outlet of the soap liquid pump and the soap liquid flow passage, under the condition that the soap liquid is filled in the liquid outlet and the soap flow, the soap is discharged from the slit of the silicone membrane, and there is no pressure difference between the opening moment of the silicone membrane and the opening state of the silicone membrane, which can cause the silicone membrane to reset to drive the slit to close after the pressure accumulation is reduced, because the volumes of the liquid outlet and the soap flow channel cannot be adjusted, the soap can continuously extrude a small amount of soap from the slit under the resetting and extrusion of the silicone membrane, so that the soap is not easily intercepted, and the soap is accumulated on the outer side of the silicone membrane to cause the phenomenon of drying and caking The volume of the compressed space (namely the compression sensitivity is insufficient), and meanwhile, the compressed space is an independent space body, and the space body is internally provided with compressible air, so that the situation that the volume of the air in the space body is changed due to the change of temperature and air pressure, and unstable factors are generated to cause liquid leakage and leakage of the silica gel membrane is caused; after a large number of tests are carried out, a second scheme is selected, namely, a condition which is communicated with the atmosphere and can change the volume is created, the problem of liquid leakage and leakage of the silicone membrane caused by the change of temperature and air pressure can be effectively solved, the expansion volume of the elastic volume expansion device is smaller than the liquid outlet volume output by the soap pump in a single pumping beat, and the silicone membrane can be opened on the premise that the liquid outlet volume of the soap liquid of the soap pump meets the volume of the soap liquid required by the expansion and pressure accumulation of the elastic volume expansion device when the soap pump outputs in a working beat; the liquid outlet is connected to the soap lye flow passage in a vertical upward or inclined upward manner, so that bubbles in the liquid outlet and the soap lye flow passage can float upward and be discharged or are discharged first, air in the liquid outlet and the soap lye flow passage can be discharged as far as possible, and the liquid leakage condition of the liquid leakage of the silica gel membrane caused by the change of temperature and air pressure can be reduced.
